Problems to be solved by the invention

However, in general, in the component mounter, a plurality of feeders are used for component feeding, and if the feeders are individually fed with components, the operation efficiency is not necessarily good, and the above-described technique cannot sufficiently cope with this.

The present invention has been made in view of the above problems, and an object thereof is to provide a technique capable of efficiently replenishing components to a feeder.

Means for solving the problems

The component replenishment support device according to the present invention comprises: a storage unit that stores a production plan for producing a board on which components are mounted by a component mounter in which a plurality of feeders each having a mounting portion are arranged in a component supply unit, the plurality of feeders supply components stored in component storage members mounted to the respective mounting portions, and a mounting head mounts the components supplied by the feeders to the board; and a calculation unit that calculates a preparation plan indicating component housing members to be held in the holding units of the replenishment carriages for preparation of the replenishment, based on the production plan, wherein the replenishment carriage having a plurality of holding units corresponding to the plurality of feeders is mounted to the component supply unit, and the component housing members held in the holding units corresponding to the plurality of replenishment feeders are collectively mounted to the mounting positions of the plurality of replenishment feeders.

The component replenishment support method according to the present invention comprises: a step of acquiring a production plan for producing a substrate on which components are mounted by a component mounter in which a plurality of feeders each having a mounting portion are arranged in a component supply portion, the plurality of feeders supply components stored in component storage members mounted to the respective mounting portions, and a mounting head mounts the components supplied by the feeders to the substrate; and calculating a preparation plan indicating component housing members to be held in holding parts of the replenishment carriage for preparation of a collective supply for collectively mounting the component housing members held in the holding parts corresponding to the plurality of replenishment feeders among the plurality of feeders on the mounting positions of the plurality of replenishment feeders by mounting the replenishment carriage having the plurality of holding parts corresponding to the plurality of feeders to the component supply part on the basis of the production plan.

In the present invention (component replenishment support device, component replenishment support method) configured as described above, component replenishment can be efficiently performed for a component mounter in which a plurality of feeders each having a mounting portion are arranged in a component supply portion, and the plurality of feeders supply components stored in component storage members mounted to the respective mounting portions. Specifically, a replenishment carriage is used for replenishing components to a feeder of a component mounter. The replenishment carriage has a plurality of holding portions corresponding to the plurality of feeders, respectively. Further, by mounting the replenishment carriage to the component supply section of the component mounter, it is possible to perform collective replenishment in which component housing members held in the holding sections corresponding to the respective plural replenishment target feeders among the plural feeders are collectively mounted to the mounting positions of the respective plural replenishment target feeders. In particular, a preparation plan indicating the component housing members to be held in the holding portion of the replenishment carriage for preparation of the replenishment at the same time is calculated based on the production plan for producing the substrate on which the components are mounted. Therefore, in parallel with component mounting by the component mounter, the component storage parts are prepared on the replenishment carriage based on the production plan, and the replenishment is performed at the timing when the replenishment is required, so that the component storage parts can be replenished to the plurality of replenishment object feeders. In this way, in the present invention, component replenishment to the feeder can be efficiently performed.

The component replenishment support device may be configured to: the preparation plan display unit is also provided for displaying the preparation plan to the operator. In this configuration, the operator can prepare the component housing member on the replenishment carriage while checking the preparation plan displayed on the preparation plan display unit.

The component replenishment support device may be configured to: the component housing member is provided with component information indicating information related to the component housed in the component housing member, and the control unit issues a warning to the operator when the result of acquiring the correspondence between the holding unit and the component information of the component housing member held in the holding unit does not conform to the preparation plan. In this configuration, when an error occurs in the preparation work of the component housing member for the replenishment carriage, a warning can be given to the operator.

The component replenishment support device may be configured to: the component housing part is provided with component information indicating information related to components housed in the component housing part, the feeder is provided with feeder information indicating information related to the feeder, and the control part obtains a correspondence between the component information of the component housing part held by the holding part and the holding part, and a correspondence between the holding part and the feeder information of the feeder corresponding to the holding part, and when the replenishment carriage is mounted to the component supply part, the component feeder information indicating the component information of the component housing part held by the holding part and the feeder in association with each other is generated for the holding part and the feeder corresponding to each other. In this configuration, component feeder information is generated in association with the mounting of the replenishment carriage to the component supply section, the component feeder information being represented by the component information of the component housing member held in the holding section and the feeder information of the feeder. Therefore, the arrangement state of the component housing member after component replenishment with respect to the feeder can be accurately grasped from the component feeder information.

The component replenishment support device may be configured to: the plurality of feeders have a detecting unit that detects the mounting of the component housing member to the mounting portion of each of the plurality of feeders, and when the replenishment trolley is mounted to the component supplying unit, the control unit generates component feeder information for the replenishment target feeder in which the mounting of the component housing member to the mounting portion is detected, and does not generate component feeder information for the replenishment target feeder in which the mounting of the component housing member to the mounting portion is not detected, among the plurality of replenishment target feeders. In this configuration, for example, when a failure occurs in the mounting of the component housing member to the replenishment target feeder due to a trouble in the transportation of the replenishment carriage, appropriate component feeder information reflecting the failure can be generated.

The component replenishment support device may be configured to: the control unit, after the replenishment trolley is mounted on the component supply unit, issues a warning to the operator when it is confirmed that there is a replenishment target feeder in which the arrangement of the component housing member to the mounting position is not detected. In this configuration, for example, when a failure occurs in the mounting of the component housing member to the replenishment target feeder due to a trouble in the transportation of the replenishment carriage, a warning can be given to the operator.

The component replenishment support device may be configured to: the plurality of feeders have a detection unit that detects the attachment of the component housing member to each attachment portion of the plurality of feeders, and the control unit gives a warning to the operator when the attachment of the component housing member to the attachment portion of the feeder other than the replenishment target feeder among the plurality of feeders is detected in association with the attachment of the replenishment carriage to the component feeding unit. In this configuration, when the component housing member is erroneously mounted to a feeder different from the feeder to be replenished, a warning can be given to the operator.

The component replenishment support device may be configured to: the component supply unit includes a reading unit that reads the identifier attached to the component supply unit, and the control unit issues a warning to the operator when the combination of the component supply unit and the component supply unit indicated by the identifier read by the reading unit is not appropriate. In this configuration, the replenishment carriage can be prevented from being attached to the wrong component supply site.

The component replenishment support device may be configured to: the component housing means is a component supply tape for housing components, a preceding tape placing unit and a subsequent tape placing unit for holding the component supply tape are capable of being engaged with and disengaged from the feeder, and when one of the preceding tape placing unit and the subsequent tape placing unit is engaged with the feeder, the component supply tape held by the one tape placing unit is mounted on a mounting portion of the feeder, the subsequent tape placing unit is mounted on the holding portion of the replenishment carriage, the component supply tape held by the subsequent tape placing unit is held by the holding portion, and when the replenishment carriage having the subsequent tape placing unit mounted on a component holding position corresponding to the replenishment feeder is mounted on the component supply portion, the preceding tape placing unit is pushed out while the preceding tape placing unit is pushed out, and is engaged with the replenishment feeder while the preceding tape placing unit is disengaged from the feeder. In this configuration, by the operation of attaching the replenishment carriage to the component supply section, the tape placement unit attached to the replenishment target feeder is replaced with the subsequent tape placement unit from the preceding tape placement unit, and the component supply tape held by the subsequent tape placement unit can be easily attached to the replenishment target feeder.

The component mounting system according to the present invention includes: the above-mentioned component supplies the supporting device; and a component mounting machine in which a plurality of feeders each having a mounting portion are arranged in the component supply portion, the plurality of feeders supply components housed in component housing members mounted to the respective mounting portions, and a mounting head mounts the components supplied by the feeders to a substrate. Therefore, the component replenishment to the feeder can be efficiently performed.

Effects of the invention

According to the present invention, the component replenishment to the feeder can be efficiently performed.

Detailed Description

Fig. 1 is a plan view schematically showing an example of a component mounter according to the present invention. Fig. 1 shows an XYZ rectangular coordinate system composed of a Z direction parallel to the vertical direction, and X and Y directions parallel to the horizontal direction. The component mounter 1 includes a pair of conveyors 12, 12 provided on a base 11. The component mounter 1 mounts components on a substrate B carried in from the upstream side in the X direction (substrate conveying direction) to a work position (position of the substrate B in fig. 1) by the conveyor 12, and carries out the substrate B after the component mounting from the work position to the downstream side in the X direction by the conveyor 12.

The component mounter 1 is provided with a pair of Y- axis rails 21, 21 extending in the Y-direction, a Y-axis ball screw 22 extending in the Y-direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 22, and a nut fixed to the Y-axis ball screw 22 in a state of being supported by the pair of Y- axis rails 21, 21 so as to be movable in the Y-direction. The head support member 23 is mounted with an X-axis ball screw 24 extending in the X-direction and an X-axis motor Mx for rotationally driving the X-axis ball screw 24, and the head unit 3 is fixed to a nut of the X-axis ball screw 24 in a state of being supported by the head support member 23 so as to be movable in the X-direction. Therefore, the head unit 3 can be moved in the Y direction by rotating the Y-axis ball screw 22 by the Y-axis motor My, or the head unit 3 can be moved in the X direction by rotating the X-axis ball screw 24 by the X-axis motor Mx.

Two component supply units 25 are arranged in the X direction on both sides of the pair of conveyors 12, 12 in the Y direction, and a plurality of tape feeders 4 are arranged in the X direction in each component supply unit 25. Each tape feeder 4 has a component feeding position 40 at a front end portion on the conveyor 12 side, and supplies components stored in a component feeding tape TP (fig. 2 and 3) to the component feeding position 40. The component supply tape TP accommodates components in each of a plurality of pockets arranged in a row at equal intervals, and the tape feeder 4 intermittently feeds the component supply tape TP in the Y direction at the intervals, thereby supplying the components to the component supply position 40. The component accommodated in the component supply tape TP is, for example, a chip-like electronic component such as an integrated circuit, a transistor, or a capacitor.

The head unit 3 has a plurality of (4) mounting heads 31 arrayed in the X direction. Each mounting head 31 has a long shape extending in the Z direction (vertical direction), and can suck and hold a component by a suction nozzle detachably mounted at the lower end thereof. That is, the mounting head 31 moves upward of the tape feeder 4, and adsorbs the components supplied from the tape feeder 4 to the component supply position 40. Next, the mounting head 31 moves upward of the substrate B in the working position to release the suction of the component, thereby mounting the component on the substrate B. In this way, the mounting head 31 performs component mounting that suctions components supplied to the component supply position 40 by the tape feeder 4 and mounts the components onto the substrate B.

Fig. 2 is a side view schematically showing an example of the structure and operation of the tape feeder. In this drawing and the following drawings, the feeding direction Df (parallel to the Y direction) in which the component feeding tape TP is fed out by the tape feeder 4 is appropriately shown, and the arrow side of the feeding direction Df is treated as "front" of the feeding direction Df, and the opposite side of the arrow of the feeding direction Df is treated as "rear" of the feeding direction Df. That is, the conveyance direction of the component supply tape TP corresponds to the front side (the other side), and the opposite side to the conveyance direction corresponds to the rear side (the one side). In order to distinguish between two component supply tapes TP that can be mounted on the tape feeder 4, different reference numerals TP1 and TP2 are appropriately used for the carrier tapes in this drawing and the following drawings.

The tape feeder 4 includes a feeder body 41 as a mechanical structure and motors Mf and Mb for driving the feeder body 41. The feeder main body 41 has a flat-shaped case 42 that is thin in the X direction and long in the feeding direction Df. A feeder ID421 composed of a bar code is attached to the side surface of the case 42. The feeder ID421 is unique and can be used to individually identify the tape feeder 4 to which the feeder ID421 is attached. The tape insertion port 43a (indicated by a broken line) extending in the Z direction is opened at the rear end of the housing 42 in the feeding direction Df, and the above-described component supply position 40 is provided on the front upper surface of the housing 42 in the feeding direction Df. The tape feeding path 43b from the tape insertion port 43a to the component feeding position 40 is provided in the feeder main body 41. The feeder body 41 receives the driving force of the motors Mf, mb and feeds the component supply tape TP inserted from the tape insertion port 43a to the tape conveying path 43b in the feeding direction Df, thereby supplying the components to the component supply position 40.

Specifically, the feeder main body 41 includes, in the case 42, a sprocket 44 disposed adjacent to the tape insertion port 43a above the tape conveying path 43b, and a gear 45 for transmitting the driving force of the motor Mb to the sprocket 44, and the sprocket 44 is rotated by the driving force of the motor Mb. The feeder main body 41 further includes a bracket 411 that can be engaged with the tape placement unit 5. The tray 411 is provided at a rear end portion of the feeder main body 41 so as to extend in the feeding direction Df and protrude rearward, and a lower side of the tray 411 serves as an arrangement space for the tape placing unit 5 engaged with the tray 411. The tape placing unit 5 engaged with the bracket 411 is opposed to the sprocket 44 from below, and the component supply tape TP is engaged with the sprocket 44 by sandwiching the component supply tape TP between the tape placing unit 5 and the sprocket 44. In this way, the component supply tape TP can be mounted on the mounting portion 441 between the sprocket 44 and the tape placing unit 5. In addition, the sprocket 44 rotates while engaging with the component tape TP, thereby enabling the component tape TP to be fed in the feeding direction Df. The feeder main body 41 includes a sprocket 47 disposed at a front end portion thereof and adjacent to the tape conveying path 43b from below, and a gear 48 for transmitting a driving force of the motor Mf to the sprocket 47, in the case 42, and the sprocket 47 is rotated by the driving force of the motor Mf. Therefore, the sprocket 47 intermittently rotates while engaging with the component tape TP, and thereby intermittently conveys the component tape TP in the feeding direction Df.

The feeder body 41 has a cutter that contacts the component tape TP on the upstream side in the feeding direction Df of the component feeding position 40. The cutter cuts the cover tape of the component supply tape TP intermittently fed in the feeding direction Df at the center and winds up the cover tape on both sides, thereby exposing the components supplied to the component supply position 40. The structure for exposing the element in this way is the same as that described in, for example, japanese patent application laid-open No. 2015-053320. However, the specific structure of exposing the element is not limited to this example. That is, the adhesive portions to which the cover tape is adhered are provided on both sides in the width direction (direction orthogonal to the longitudinal direction) of the component supply tape TP so as to sandwich the component housing portions (pockets). The components may also be exposed by peeling one of the adhesive portions while the other adhesive portion remains, and rolling up the cover tape.

Step S11 corresponds to a state in which the component supply tape TP1 is used for component mounting by the mounting head 31. That is, the component supply tape TP1 is inserted into the feeder main body 41 along the tape conveying path 43B, and the sprocket 47 intermittently conveys the component supply tape TP1 in the feeding direction Df, thereby supplying the component to be mounted on the substrate B to the component supply position 40. Further, in step S11, the front end of the component supply tape TP2 for component mounting following the component supply tape TP1 is mounted between the sprocket 44 and the tape placing unit 5. In this way, the component supply tape TP2 to be used next stands by at the rear end portion of the feeder main body 41.

As shown in step S12, when the component in the component supply tape TP1 is exhausted and the tape feeder 4 discharges the component supply tape TP1, the loading shown in step S13 is performed. Specifically, the sprocket 44 starts to rotate, and the component tape TP2 is fed out in the feeding direction Df toward the component feeding position 40, so that the tip end of the component tape TP2 engages with the sprocket 47. Next, in step S14, for example, when the operator removes the tape placing unit 5 from the housing 42, the component supply tape TP2 is separated from the sprocket 44 and falls down toward the tape conveying path 43 b. Thus, the sprocket 47 can intermittently feed the component feeding tape TP2 in the feeding direction Df and feed the components in the component feeding tape TP2 to the component feeding position 40. Incidentally, intermittent conveyance of the component supply tape TP may be performed in a state where the tape placing unit 5 is mounted to the housing 42. Specifically, the sprocket 44 may be provided with a one-way clutch that rotates in response to movement of the component supply tape TP to the front side in the feeding direction Df when the motor Mb is stopped, and that restricts movement of the component supply tape TP to the rear side in the feeding direction Df.

Fig. 3 is a diagram schematically showing a relationship between the component supply reel holding the component supply tape and the tape feeder. The component supply reel 6 has an axial center 61 and two side plates 62 sandwiching the axial center 61 from both sides, and supports the component supply tape TP wound around the axial center 61 from both sides via the side plates 62. The component supply reel 6 has a reel ID63 and a component ID64 each formed of a bar code on the side plate 62. The reel ID63 is unique and can be used to individually identify the component supply reel 6 to which the reel ID63 is attached. The component ID64 indicates information (type, number, etc. of components) related to the components stored in the component supply tape TP of the component supply reel 6 to which the component ID64 is attached. The reel ID63 and the component ID64 are not necessarily constituted by separate bar codes, and may be constituted by one bar code.

In this way, the two component supply reels 6 are disposed with respect to the one tape feeder 4, and the two component supply tapes TP pulled out from the two component supply reels 6 can be attached to the one tape feeder 4. Of these two component supply reels 6, one component supply reel 6 is held at a lower holding position Ll, and the other component supply reel 6 is held at an upper holding position Lu above the lower holding position Ll.

In contrast, the component mounter 1 includes: a feeder mount carriage 7 that holds the component supply reel 6 at a lower holding position Ll; and a component replenishment carriage 8 that holds the component supply reel 6 at the upper holding position Lu. The specific structures of the feeder shoe 7 and the component replenishment shoe 8 will be described later, and these are schematically and simplified in fig. 3. The feeder mount carriage 7 and the component replenishment carriage 8 are detachably mounted to the component supply section 25. As described later, the tape feeder 4 is detachably mounted to the feeder mount carriage 7, and the feeder mount carriage 7 functions to hold the tape feeder 4 in addition to the function of holding the component supply reel 6. The feeder mount carriage 7 is mainly used for preparation work for disposing the tape feeder 4 and the component supply reel 6 in the component supply section 25, and the component replenishment carriage 8 is mainly used for replenishment work for replenishing the component supply reel 6 to the component supply section 25.

Note that, all the tape feeders 4 mounted on the component supply unit 25 are not limited to the type shown in fig. 2 (referred to as "self-loading type" in this specification). Therefore, a part of the tape feeders 4 of the component supply section 25 may be of a type capable of mounting only a single component supply tape TP. The component supply reel 6 around which the component supply tape TP mounted on the tape feeder 4 of this type is wound is held by the feeder mount carriage 7, but is not held by the component replenishment carriage 8.

Fig. 4 and 5 are right rear perspective views of the feeder shoe and the component replenishment carriage, as viewed from the right obliquely rear, and fig. 6 is a left rear perspective view of the feeder shoe and the component replenishment carriage, as viewed from the left obliquely rear. In fig. 4, a state in which the tape feeders 4 and the component supply reels 6 are removed from the feeder mount carriage 7 and the component supply reels 6 are removed from the component supply carriage 8 is shown, in fig. 5, a state in which the plurality of tape feeders 4 and one component supply reel 6 are held in the feeder mount carriage 7 and the plurality of component supply reels 6 are held in the component supply carriage 8 is shown, and in fig. 6, a state in which one tape feeder 4 is held in the feeder mount carriage 7 and the component supply reel 6 is removed from the feeder mount carriage 7 and the component supply carriage 8 is shown.

The feeder mount carriage 7 has a horizontally arranged bottom plate 711 and two side wall plates 712 vertically erected from both ends of the bottom plate 711 in the X direction. The bottom plate 711 has a peripheral edge formed of two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is rectangular in plan view. The side wall plates 712 are mounted to the bottom plate 711 in parallel with the feeding directions Df and Z. In addition, the feeder mount carriage 7 has a beam 713 extending in the X direction between the two side wall plates 712. The beam 713 is erected between the upper ends of the both side wall plates 712 at the front ends of the both side wall plates 712.

The feeder mount carriage 7 further includes casters 714 attached to four corners of the lower surface of the base plate 711, and these casters 714 support the base plate 711 on the ground (the installation surface of the feeder mount carriage 7). Therefore, the feeder attachment cart 7 can move the casters 714 while rotating according to an external force from an operator, an unmanned transport vehicle, or the like. In particular, handles 715 protruding obliquely upward and rearward are provided on the two side wall plates 712, respectively, and an operator can move the feeder attachment cart 7 by operating the handles 715.

The feeder mount carriage 7 has a mount plate 716 mounted on the upper end of the beam 713, and two side plates 717 mounted on both ends of the mount plate 716. The mounting plate 716 is disposed horizontally, and each side plate 717 protrudes from the mounting plate 716 toward the front side in the feeding direction Df. The feeder mount carriage 7 further has a support plate 718 extending in the X direction between two side plates 717. The support plate 718 is erected between the lower ends of the two side plates 717 and horizontally disposed.

The feeder mount carriage 7 has two engagement protrusions 719a, 719b arranged parallel to the feeding direction Df on the inner side of the side plate 717. These engagement projections 719a, 719b protrude inward from the inner wall of the side plate 717 (i.e., toward the space sandwiched by the two side plates 717 in the X direction). The engagement protrusion 719a is disposed further to the rear than the engagement protrusion 719b in the feeding direction Df.

The feeder mount carriage 7 has a feeder mount portion 73 disposed between two side plates 717 and above a support plate 718, and the feeder mount portion 73 is supported by the two side plates 717 and the support plate 718. In the feeder mounting portion 73, a plurality of feeder slots 731 (placement positions S) are arranged in the X direction, and the tape feeders 4 can be detachably mounted in the respective feeder slots 731.

The feeder mount carriage 7 further includes a reel holding portion 75 disposed between the two side wall plates 712 and above the bottom plate 711, and the reel holding portion 75 is supported by the two side wall plates 712. In the reel holding portion 75, a plurality of reel holders 751 (reel holding positions) are arranged in the X direction, and the component supply reel 6 can be detachably attached to each of the reel holders 751. Each of the reel holders 751 holds the mounted component supply reel 6 at the lower holding position Ll (fig. 3).

In the feeder mount carriage 7, a plurality of reel holders 751 are provided corresponding to the plurality of feeder slots 731, respectively. That is, the component supply tape TP pulled out from the component supply reel 6 held by one reel holder 751 is mounted on the tape feeder 4, and the tape feeder 4 is mounted to the feeder slot 731 corresponding to the one reel holder 751.

The feeder mount carriage 7 has a discard box 77 placed on the upper surface of the bottom plate 711 below the feeder mount section 73 and the reel holding section 75. The component supply tape TP discharged from the tape feeder 4 is discarded to the discard box 77.

The component replenishment carriage 8 has a bottom plate 811 and an insertion plate 812 each arranged horizontally. The bottom plate 811 has a peripheral edge formed of two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is rectangular extending in the X direction in a plan view. The insertion plate 812 has a peripheral edge formed of two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and has a rectangular shape extending in the feeding direction Df in a plan view. The insertion plate 812 is attached to the bottom plate 811 so as to protrude from the center of the bottom plate 811 in the X direction toward the front side in the feeding direction Df.

The component replenishment carriage 8 has two side wall plates 813 erected perpendicularly from both ends of the bottom plate 811 in the X direction. Each side wall plate 813 is attached to the bottom plate 811 in parallel with the feeding direction Df and the Z direction. The component replenishment carriage 8 further includes a beam 814 extending in the X direction between the two side wall plates 813. The beam 814 is erected between the upper ends of the side wall plates 813 at the rear ends of the side wall plates 813.

The component replenishment carriage 8 further includes: casters 815 mounted on both ends of the bottom plate 811 in the X direction; and casters 815 attached to both sides in the X direction at the front end of the insertion plate 812 in the feeding direction Df, and these casters 815 support the bottom plate 811 and the insertion plate 812 on the ground. Therefore, the component replenishment carriage 8 can move the casters 815 while rotating according to an external force from an operator, an unmanned carrier, or the like. In particular, the beam 814 functions as a handle, and the operator can move the component replenishment carriage 8 by operating the beam 814.

The component replenishment carriage 8 has two side plates 816 attached to the upper ends of the two side wall plates 813, respectively. Each side plate 816 protrudes from the side wall plate 813 toward the front side in the feeding direction Df. A slit 817 extending parallel to the feeding direction Df is provided at the front end of each side plate 816. The slits 817 are opened forward in the feeding direction Df and are arranged at the same height as the engaging protrusions 719a, 719b of the feeder shoe 7.

The component replenishment carriage 8 has a unit mounting portion 83 arranged so as to be sandwiched between two side plates 816, and the unit mounting portion 83 is supported by the two side plates 816. In the unit mounting portion 83, a plurality of unit slots 831 (placement positions S) are arranged in the X direction, and the tape placement unit 5 can be detachably mounted to each of the unit slots 831. The plurality of unit slots 831 are provided corresponding to the plurality of feeder slots 731 in the feeder mount carriage 7, respectively. In particular, as described later, in a state where the component replenishment carriage 8 is mounted on the feeder mount carriage 7, one unit insertion slot 831 and one feeder insertion slot 731 that are mutually corresponding are positioned at the same position (placement position S) in the X direction.

The component replenishment carriage 8 further includes a reel mounting table 85 disposed so as to be sandwiched between the two side plates 816, and the reel mounting table 85 is supported by the two side plates 816 at a rear side in the feeding direction Df from the unit mounting portion 83. The spool mount 85 has a concave shape recessed downward, has a front inclined plate 851 climbing toward the front side at the front end, and has a rear inclined plate 852 climbing toward the rear side at the rear end. The spool mounting table 85 further includes a mounting plate 853 provided between the front swash plate 851 and the rear swash plate 852 in the feeding direction Df, and the component supply spool 6 can be mounted on the mounting plate 853.

The component supply tape TP pulled out from the component supply reel 6 held on the reel mounting table 85 can be held by the tape placement unit 5 attached to the unit attachment portion 83. As described below, the component replenishment carriage 8 is detachably attached to the feeder attachment carriage 7, and the reel mounting table 85 holds the component supply reel 6 mounted on the mounting plate 853 at the upper holding position Lu (fig. 3) in a state where the component replenishment carriage 8 is attached to the feeder attachment carriage 7.

Fig. 7 to 10 are diagrams showing the mounting operation of the component replenishment carriage on the feeder mounting carriage. In particular, fig. 7 is a side view showing a state before the component replenishment carriage 8 is mounted away from the feeder-mounting carriage 7, fig. 8 is a side view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage, fig. 9 is a bottom view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage, and fig. 10 is a perspective view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage.

The component replenishment carriage 8 is moved toward the feeder attachment carriage 7 from a state (state shown in fig. 4 to 7) in which the two side plates 816 face the inner sides of the two side plates 717 of the feeder attachment carriage 7 in the X direction as viewed from the feeding direction Df. As shown in fig. 7 to 8, the operation of the component replenishment carriage 8 up to the feeder attachment carriage 7 is as follows.

Each side plate 816 of the component replenishment carriage 8 is located above the reel holding portion 75, and as the component replenishment carriage 8 moves toward the feeder attachment carriage 7, each side plate 816 passes above the reel holding portion 75 (and the component supply reel 6 held by the reel holding portion 75). The insertion plate 812 of the component replenishment carriage 8 is positioned below the bottom plate 711 of the feeder carriage 7, and the insertion plate 812 is inserted between the bottom plate 711 and the floor surface.

In the Z direction, the width of each slit 817 of the component replenishment carriage 8 is the same as the width (including play) of the engagement projections 719a, 719b, and the slit 817 engages (fits) with the engagement projection 719a and then engages (fits) with the engagement projection 719 b. Thereby, the position of the side plate 816 of the component replenishment carriage 8 is restrained and positioned in the horizontal direction with respect to the position of the side plate 717 of the feeder attachment carriage 7.

In the X direction, the distance between the inner wall surfaces of the two side plates 717 of the feeder shoe 7 is the same as the distance (including play) between the outer wall surfaces of the two side plates 816 of the component replenishment shoe 8, and the two side plates 816 of the component replenishment shoe 8 are engaged (fitted) between the two side plates 717 of the feeder shoe 7. Thereby, the position of the unit mounting portion 83 of the component replenishment carriage 8 is restricted and positioned in the X direction with respect to the position of the feeder mounting portion 73 of the feeder mounting carriage 7. As described above, the plurality of unit slots 831 respectively correspond to the plurality of feeder slots 731. Therefore, in a state of being positioned in the X direction, one unit slot 831 and one feeder slot 731 corresponding to each other (i.e., located at the same placement position S) are opposed in the feeding direction Df.

As shown in fig. 9, two guide members 72 are provided on the bottom surface of the bottom plate 711 in front of the feeding direction Df of the two casters 714, and these guide members 72 also perform a positioning function. That is, the two guide members 72 are provided so as to extend parallel to the feeding direction Df and face each other with a gap corresponding to the width of the insertion plate 812 therebetween in the X direction. Therefore, when the insertion plate 812 advancing forward in the feeding direction Df is inserted between the two guide members 72 through between the two casters 714, the two guide members 72 restrict the position of the insertion plate 812 from both sides in the X direction. Thereby, the feeder mount carriage 7 and the component replenishment carriage 8 are positioned with each other in the X direction, and one unit slot 831 and one feeder slot 731 corresponding to each other are opposed in the feeding direction Df.

Then, finally, as shown in fig. 8 to 10, the bottom plate 811 of the component replenishment carriage 8 abuts against the bottom plate 711 of the feeder attachment carriage 7. Thus, the component replenishment carriage 8 is mounted on the feeder mounting carriage 7.

In addition, with the above-described mounting work, a unit replacement is performed in which the tape placement unit 5 mounted on the tape feeder 4 is replaced. Next, after explaining the structure of the tape placement unit 5, unit replacement will be described.

Fig. 11 is a perspective view showing the structure of the tape placing unit, fig. 12A is a side view showing the structure of the tape placing unit, fig. 12B is a cross-sectional view showing the structure of the tape placing unit, fig. 13 is a plan view showing the structure of the tape placing unit, and fig. 14 is a front view showing the structure of the tape placing unit.

The tape placement unit 5 includes: a base frame 51; a support frame 52 opposed to the base frame 51 from above; and a plurality of (two) compression coil springs 53 disposed between the base frame 51 and the support frame 52. The plurality of compression coil springs 53 are arranged in the feeding direction Df, and apply a biasing force (elastic force) to separate the base frame 51 and the support frame 52 from each other in the Z direction to the base frame 51 and the support frame 52.

The base frame 51 has a base body 511 extending in the feeding direction Df. The susceptor body 511 has a bottom surface 511a formed flat. In addition, the base frame 51 has: an upward extending portion 512 extending upward from a front end of the feeding direction Df of the susceptor body 511; and a front projection 513 projecting forward of the feeding direction Df from an upper end of the upward extending portion 512. The base frame 51 further includes a side wall plate 514 extending in the feeding direction Df at one end of the upper surface of the base body 511 in the X direction. The side wall plate 514 protrudes upward from the base body 511.

The support frame 52 has a support main 521 extending in the feeding direction Df. The support body 521 is opposed to the base body 511 of the base frame 51 from above, and the support body 521 overlaps the base body 511 in a plan view from above. The support main 521 has a horizontally formed tape mounting portion 521a on its upper surface, and the component supply tape TP can be mounted on the tape mounting portion 521 a. That is, the support frame 52 supports the component supply tape TP placed on the tape placement portion 521a of the support body 521. Further, an engagement hole 521b penetrating in the X direction is formed in the support body 521.

In addition, the support frame 52 has: a downward extending portion 522 extending downward from a front end of the support main 521 in the feeding direction Df; and a rear projection 523 projecting rearward in the feeding direction Df from a lower end of the downward extending portion 522. The rear projection 523 of the support frame 52 is opposed to the front projection 513 of the base frame 51 from below. In addition, the support frame 52 has: a downward extending portion 524 extending downward from a rear end of the support main 521 in the feeding direction Df; and a rear projection 525 projecting rearward in the feeding direction Df from a lower end of the downward extending portion 524.

The tape placement unit 5 further includes a rear frame 54 disposed rearward of the base body 511. The rear frame 54 has a rear body 541 attached to a rear end of the base body 511 in the feeding direction Df. The rear body 541 extends in the Z direction and protrudes upward from the susceptor body 511, and the bottom surface 541a of the rear body 541 and the bottom surface 511a of the susceptor body 511 are included in the same plane (i.e., coplanar). The rear frame 54 further includes a front projection 542 projecting forward in the feeding direction Df from the upper end of the rear body 541. The front projection 542 of the rear frame 54 is opposed to the rear projection 525 of the support frame 52 from above.

The plurality of compression coil springs 53 are arranged between the upper extending portion 512 of the base frame 51 and the lower extending portion 524 of the support frame 52 in the feeding direction Df. The lower end of each compression coil spring 53 is in contact with the upper surface of the base body 511 of the base frame 51, and the upper end of each compression coil spring 53 is in contact with the lower surface of the support body 521 of the support frame 52. Accordingly, the support frame 52 is biased in a direction (Z direction) away from the base frame 51 by the compression coil springs 53. In contrast, the front projections 513 and 542 face the rear projections 523 and 525 provided on both sides of the feeding direction Df of the support frame 52 from above. Accordingly, in a state where no external force is applied against the biasing force of each compression coil spring 53, the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front Fang Tuqi and the front projection 542, respectively, by the biasing force of each compression coil spring 53, and the support frame 52 is stationary with respect to the base frame 51 at the uppermost point.

The compression coil springs 53 are fitted to support rods 531 protruding upward from the upper surface of the base body 511. The support bar 531 is provided to extend parallel to the Z direction and is attached to the upper surface of the susceptor body 511. On the other hand, the support body 521 is provided with an insertion hole into which the support bar 531 can be inserted in the Z direction, and the support bar 531 enters the insertion hole of the support body 521 as the base frame 51 approaches the support frame 52.

The tape placement unit 5 includes a lever 55 rotatably attached to a side wall plate 514 of the base frame 51. The lever 55 has a lever frame 551 disposed between the side wall plate 514 and the support frame 52 in a plan view. A long hole 551a is penetrated in the X direction at the front end of the lever frame 551, a bolt 56 having a head portion larger than the width of the long hole 551a is inserted into the long hole 551a from the opposite side of the side wall plate 514, and the bolt 56 is screwed with the side wall plate 514. In this way, the lever 55 is rotatably attached to the side wall plate 514 around a bolt 56 (rotation axis) parallel to the X direction. The lever 55 further includes an engagement projection 552 projecting in the X direction from the lever frame 551. The engagement projection 552 is inserted into the engagement hole 521b of the support frame 52.

The lever 55 further has a hood 553 attached to the rear end of the lever frame 551 in the feeding direction Df. The tape cover 553 has: a side wall plate 553a extending upward from the rear end of the feed direction Df of the lever frame 551; an abutting plate 553b extending in the X direction from the side wall plate 553a toward the opposite side of the side wall plate 514; and a side wall plate 553c extending downward from an end portion of the abutting plate 553b on the opposite side of the side wall plate 514. The abutting plate 553b spans the rear end portion of the support frame 52 and the front end portion of the rear frame 54 in the X direction, and the side wall plates 553a and 553c are located on both sides of the rear end portion of the support frame 52 and the front end portion of the rear frame 54 in the X direction. Further, the tape cover 553 has an abutment portion 553d protruding inward (i.e., side wall plate 553c side) from the front end of the side wall plate 553 a.

The tape placement unit 5 includes a bracket 57 disposed behind the rear frame 54. The carriage 57 has a carriage main body 571 mounted to a rear end of the rear frame 54 in the feeding direction Df. The bracket main body 571 is erected in the Z direction and protrudes upward from the rear frame 54, and the bottom face 571a of the bracket main body 571 and the bottom face 541a of the rear main body 541 are included in the same plane (i.e., coplanar).

The bracket 57 further has a unit engagement protrusion 572 provided at an upper end of the bracket main body 571. The unit engagement protrusion 572 is located at the uppermost portion of the tape placing unit 5. The unit engagement protrusion 572 has: an upward extending portion 572a extending upward from an upper end of the bracket main body 571; and flanges 572b and 572c protruding from the upper end of the upward extending portion 572a to both sides in the X direction, the unit engagement protrusion 572 having a T-shape when viewed from the feeding direction Df. These flanges 572b and 572c are each provided to extend in the feeding direction Df.

The bracket 57 has a unit engagement hole 573 provided at the lower end of the bracket main body 571. The unit engagement hole 573 has: an upward extending hole 573a extending upward from a lower end of the bracket main body 571; and grooves 573b, 573c protruding from the upper end of the hole 573a toward both sides in the X direction, the unit engagement hole 573 being configured in a T-shape when viewed from the feeding direction Df. These grooves 573b, 573c extend in the feeding direction Df. The unit engagement holes 573 are opened on both sides (front and rear sides) in the feeding direction Df. The unit engagement hole 573 and the unit engagement protrusion 572 have the same shape and size as viewed from the feeding direction Df, and are congruent.

The carriage 57 further has a tape introduction hole 574 penetrating the carriage main body 571 in the feeding direction Df. Thus, a tape guide path is formed from the tape guide hole 574 to the tape mounting portion 521a of the support frame 52 via the upper surface of the rear frame 54. Next, a tape placement operation for causing the tape placement unit 5 to hold the component supply tape TP will be described.

Fig. 15 is a perspective view showing a first step of a tape placement operation to a tape placement unit, fig. 16A is a side view showing a first step of a tape placement operation to a tape placement unit, fig. 16B is a cross-sectional view showing a first step of a tape placement operation to a tape placement unit, fig. 17 is a perspective view showing a second step of a tape placement operation to a tape placement unit, fig. 18A is a side view showing a second step of a tape placement operation to a tape placement unit, fig. 18B is a cross-sectional view showing a second step of a tape placement operation to a tape placement unit, fig. 19A is a side view showing a third step of a tape placement operation to a tape placement unit, and fig. 19B is a cross-sectional view showing a third step of a tape placement operation to a tape placement unit. Further, the tape placement work is performed by an operator.

As shown in fig. 15, 16A, and 16B, in the first step of the tape placing operation, the component supply tape TP is placed on the tape placing portion 521a of the support frame 52. In fig. 15, 16A and 16B, only a part of the component supply tape TP (the vicinity of the tape mounting portion 521 a) is shown. The component tape TP is placed by inserting the front end of the component tape TP through the tape introduction hole 574 in the rear direction of the feeding direction Df, and introducing the component tape TP to the tape placement portion 521 a. At this time, the support frame 52 rises relative to the base frame 51 to the uppermost point where the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front projection 513 and the front projection 542, respectively. Therefore, the lever 55 engaged with the engagement hole 521b of the support frame 52 via the engagement projection 552 is stationary in a state rotated upward as the support frame 52 rises toward the topmost point.

As shown in fig. 17, 18A, and 18B, in the second step of the tape placing operation, the operator presses the tape cover 553 of the lever 55 against the urging force of each compression coil spring 53. Thereby, the lever 55 rotates downward, and the support frame 52 is pressed by the lever 55 via the engagement projection 552 engaged with the engagement hole 521b, and moves downward. Then, when the lower portion of the lever 55 abuts against the base frame 51, the rotation of the lever 55 is stopped. In this state, the elongated hole 551a is extended in the direction parallel to the feeding direction Df. The tape cover 553 covers the component supply tape TP from the tape introduction hole 574 to the tape mounting portion 521 a. Specifically, the abutting plate 553b of the tape cover 553 abuts on the upper surface of the component supply tape TP to restrain the component supply tape TP (tape restrained state). By this tape restraining state, the movement of the component supply tape TP is hindered. Side wall plates 553a and 553b of tape cover 553 sandwich component supply tape TP from the X direction.

In the third step of the tape laying operation, the operator pushes out the lever 55, which has stopped rotating, forward in the feeding direction Df. That is, since the rod 55 is screwed to the bolt 56 via the long hole 551a, the rod 55 can be displaced in the feeding direction Df with respect to the bolt 56 in a state where the long hole 551a is parallel to the feeding direction Df. Further, in this third step, the rotation of the lever 55 can be restricted against the urging force of the compression coil spring 53. That is, as shown in fig. 19A and 19B, the front projection 551B projects forward from the front end of the lever frame 551 of the lever 55 in the feeding direction Df. In contrast, a limiting plate 554 having a predetermined thickness is disposed at the front end portion of the upper surface of the base frame 51. As will be described later, the front projection 551b of the lever 55 functions as a rotation restriction key, and the restriction plate 554 functions as a rotation restriction stopper, and the front projection 551b contacts (engages) the restriction plate 554, thereby restricting the rotation of the lever 55.

As shown in fig. 18B, before the rotation of the lever 55 is stopped and the operator pushes out the lever 55, the bolt 56 is brought into contact with the tip of the long hole 551a in the feeding direction Df, and the lever 55 is positioned at the retracted position Le1 where the front protrusion 551B of the lever 55 is retracted rearward in the feeding direction Df from the restriction plate 554. The lever 55 is rotatable in a state where the lever 55 is located at the retracted position Le1. On the other hand, as shown in fig. 19B, after the operator pushes out the lever 55, the lever 55 is located at a contact position Lc where the bolt 56 contacts the rear end of the long hole 551a in the feeding direction Df and the front protrusion 551B of the lever 55 contacts the upper surface of the restriction plate 554. In a state where the lever 55 is located at the contact position Lc, the downward movement of the front projection 551b accompanying the rotation of the lever 55 is restricted by the restricting plate 554 contacting the front projection 551b from the lower side. That is, the rotation of the lever 55 is restricted by the restricting plate 554.

In this way, the tape placement unit 5 holding the component supply tape TP can be attached to the tape feeder 4 (fig. 20A, 20B, and 21). Fig. 20A is a side view showing a state of the tape placement unit when the tape feeder is mounted, fig. 20B is a side view showing a state of the tape placement unit when the tape feeder is mounted, and fig. 21 is a perspective view showing a state in which the tape placement unit is mounted. As shown in fig. 20B, when the tape placement unit 5 is mounted on the tape feeder 4, the lever 55 is returned to the rear in the feeding direction Df with respect to the restricting plate 554 by a function of a lever release boss 41e (fig. 25B, 27B, 29B, etc.), which will be described later, and is retracted from the contact position Lc to the retracted position Le2. The front projection 551b of the lever 55 located at the retracted position Le2 is retracted from the restricting plate 554 to the rear side in the feeding direction Df. Thereby, the lever 55 can be rotated by the urging force of the compression coil spring 53, and the belt-restrained state is released.

The retreat position Le2 is located between the contact position Lc and the retreat position Le1 in the feeding direction Df, in other words, is located on the rear side of the contact position Lc and on the front side of the retreat position Le 1. Fig. 20B shows a state immediately before the rotatable lever 55 is positioned at the retracted position Le2, and in this state, a gap Δ is provided between the front end (right end in fig. 20B) of the long hole 551a in the feeding direction Df and the bolt 56. As described later, the gap Δ is provided to ensure a movement amount of the tape placement unit 5 (further, a member other than the lever 55) required to separate from the tape feeder 4 by pressing the tape placement unit 5 attached to the tape feeder 4 toward the front side in the feeding direction Df, and corresponds to a distance between the retracted position Le1 and the retracted position Le2. In this way, in a state where the tape placing unit 5 is attached to the tape feeder 4, the lever 55 is positioned at the retreat position Le2, and a gap Δ is secured between the front end of the long hole 551a and the bolt 56.

As shown in fig. 21, a feeder engagement hole 412 is provided at the rear end of the carrier 411 of the tape feeder 4 in the feeding direction Df. Specifically, the bracket 411 has: a tray main body 411a having a rectangular parallelepiped shape extending in the feeding direction Df; and a tray protruding portion 411b protruding downward from the tray main body 411a at a rear end of the tray main body 411a in the feeding direction Df. The feeder engaging holes 412 are provided so as to penetrate the tray protruding portion 411b in the feeding direction Df, and thereby open at both ends of the tray protruding portion 411b in the feeding direction Df. The feeder engagement hole 412 has: an upward extending hole 412a extending upward from the lower end of the bracket 411; and grooves 412b, 412c protruding from the upper end of the hole 412a to both sides in the X direction, the feeder engaging hole 412 being formed in a T shape. These grooves 412b and 412c extend in the feeding direction Df. The feeder engagement holes 412 are opened on both sides (front side and rear side) in the feeding direction Df. The feeder engaging hole 412 and the unit engaging protrusion 572 have the same shape and size as viewed from the feeding direction Df, and are congruent. Therefore, the worker can attach the tape placement unit 5 to the tape feeder 4 by inserting the unit engagement protrusion 572 of the tape placement unit 5 that holds the component supply tape TP into the feeder engagement hole 412 of the tape feeder 4 from the rear in the feeding direction Df. In this way, in the tape placement unit 5 (i.e., the tape placement unit 5 attached to the tape feeder 4) in which the unit engagement protrusion 572 is engaged with the feeder engagement hole 412 at the engagement position Lg, the lever 55 is located at the retracted position Le2 as described above.

As described above, with the attachment of the subsequent tape placement unit 5 to the tape feeder 4, the replacement of the unit in which the preceding tape placement unit 5 is detached from the tape feeder 4 can be performed using the component replenishment carriage 8.

Fig. 22 is a perspective view showing a preparation operation performed on the component replenishment carriage by the operator for replacement of the unit, fig. 23A is a partial horizontal cross-sectional view showing a locking mechanism provided in the component replenishment carriage, fig. 23B is a partial vertical cross-sectional view showing a locking mechanism provided in the component replenishment carriage, and fig. 23C is a view schematically showing a locking mechanism provided in the component replenishment carriage in a vertical cross-section. Fig. 23C is a schematic diagram, and is different from fig. 23A and 23B in terms of size. As described above, in the unit mounting portion 83 of the component replenishment carriage 8, the plurality of unit slots 831 are arranged in the X direction. Each of the unit insertion grooves 831 is a T-shaped engagement protrusion having the same shape and size as the above-described unit engagement protrusion 572, and an operator can attach the tape placement unit 5 to the unit insertion groove 831 by inserting the unit engagement hole 573 of the tape placement unit 5 into the unit insertion groove 831 from the feeding direction Df.

The component replenishment carriage 8 has a locking mechanism 87 shown in fig. 23A to 23C. The lock mechanism 87 includes: a plurality of locking keys 871 provided in correspondence with the plurality of unit slots 831, respectively; and a lever 873 extending in the X direction, and a plurality of lock keys 871 are attached to the lever 873. The lever 873 is supported so as to be movable in the X direction with respect to the unit mounting portion 83, and an operator can switch between the "unlocked state" and the "locked state" shown in fig. 23A to 23C by operating a handle 875 provided at one end of the lever 873 in the X direction to move the lever 873 in the X direction.

The unit slot 831 has: an upper extension portion 831a extending in the Z direction; and flanges 831b and 831c protruding from the upper end of the upper extension portion 831a toward both sides in the X direction, the unit insertion groove 831 is configured to have a T-shape when viewed from the feeding direction Df. These flanges 831b and 831c are each provided to extend in the feeding direction Df. In addition, the inside of the upper extension portion 831a is partially formed to be hollow, and the unit socket 831 has a hollow portion 831d inside the upper extension portion 831 a. The hollow 831d is opened downward and to one side in the X direction. In contrast, the lever 873 extends in the X direction below the bracket 57 of the tape placing unit 5 attached to the unit insertion groove 831, and the lock key 871 extends from the lever 873 into the hollow 831d through the opening below the hollow 831d.

In addition, the bracket 57 of the tape placing unit 5 has a hollow portion 575 inside, and in a state where the bracket 57 of the tape placing unit 5 is attached to the unit socket 831, the hollow portion 575 of the bracket 57 and the hollow portion 831d of the unit socket 831 are adjacent to each other in the X direction to communicate with each other. In the "unlocked state", the lock key 871 is stored in the upper extension 831a and retreats from the hollow 575. Therefore, the tape placing unit 5 can be detached from the unit insertion groove 831. On the other hand, in the "locked state", the lock key 871 protrudes from the upper extension 831a toward the hollow 575. As a result, the lock key 871 engages with the hollow 575 of the tape placing unit 5, and removal of the tape placing unit 5 from the unit slot 831 is inhibited.

Therefore, when the tape placing unit 5 is mounted in the unit insertion groove 831, the operator appropriately operates the handle 875 to retract the lock key 871 from the hollow portion 575 (unlocked state), and inserts the unit engagement hole 573 of the tape placing unit 5 into the unit insertion groove 831. Next, the operator operates the handle 875 to engage the lock key 871 with the hollow 575 of the tape placing unit 5 (locked state).

In fig. 22, the component supply tape TP is omitted, but the operator mounts the tape placement unit 5 holding the component supply tape TP pulled out from the component supply reel 6 in the unit insertion slot 831. Accordingly, the operator mounts the component supply reel 6 on the reel mounting table 85, and the component supply reel 6 is wound with the component supply tape TP held by the tape mounting unit 5 attached to the unit slot 831. Thus, the preparation work for the component replenishment carriage 8 is completed. In fig. 22, a case is shown in which a pair of tape placement units 5 and component supply reels 6 are placed on the component replenishment carriage 8, but an operator can appropriately place a plurality of pairs of tape placement units 5 and component supply reels 6 on the component replenishment carriage 8.

Fig. 24 to 32C are diagrams showing operations performed in connection with replacement of the unit. In these figures, a preceding tape placement unit 5 attached to the tape feeder 4 before replacement is denoted as a tape placement unit 5A, and a subsequent tape placement unit 5 attached to the tape feeder 4 after replacement is denoted as a tape placement unit 5B. In order to clearly show the state of the tape placement unit 5 within the range hidden by the side wall of the tape feeder 4, the side wall is appropriately shown in perspective. As shown in fig. 22, this unit replacement is performed by attaching the component replenishment carriage 8, to which the tape placement unit 5 and the component supply reel 6 are attached, to the feeder attachment carriage 7 in the same manner as the above-described attachment operation.

At the start time of the mounting operation, the unit engagement protrusion 572 of the preceding tape placement unit 5A is located at an engagement position Lg (i.e., a position of the feeder engagement hole 412) with the feeder engagement hole 412 of the tape feeder 4, and the preceding tape placement unit 5A is mounted to the bracket 411 (fig. 21 and 24) of the tape feeder 4. As shown in fig. 25B, the tape feeder 4 is provided with a support boss 4e (support portion), and the tape placement unit 5 is provided with a support slit 5e (supported portion) that opens forward in the feeding direction Df, and the support slit 5e engages (is fitted) with the support boss 4e from the rear side in the feeding direction Df. That is, the support boss 4e of the tape feeder 4 supports the tape placing unit 5 (the preceding tape placing unit 5A) attached to the tape feeder 4 by engaging with the support slit 5e of the tape placing unit 5. In this way, the tape placement unit 5 attached to the tape feeder 4 (feeder main body 41) can be firmly supported by the support boss 4 e. From this state, the subsequent tape placement unit 5B attached to the component replenishment carriage 8 moves in the feeding direction Df toward the engagement position Lg in accordance with the attachment operation (fig. 24 to 26). Then, the front end of the subsequent tape placing unit 5B contacts the rear end of the preceding tape placing unit 5A (fig. 27A, 27B).

The feeder main body 41 of the tape feeder 4 includes a lever release boss 41e. In contrast, in the process of attaching the preceding tape placement unit 5A to the tape feeder 4, the lever 55 of the tape placement unit 5A is brought into contact with the lever release boss 41e, and is pushed rearward by the lever release boss 41e with respect to the restricting plate 554. Thereby, the state of the tape placing unit 5 shifts from the state of fig. 18B described above to the state of fig. 20B. Accordingly, the preceding tape placing unit 5A shown in fig. 25B is in the state of fig. 20B.

When the subsequent tape placing unit 5B in contact with the preceding tape placing unit 5A is further advanced toward the front side, the preceding tape placing unit 5A is pushed out toward the front side. However, the lever 55 of the preceding tape placement unit 5A abuts against the lever release boss 41e, and the movement of the front side of the lever release boss 41e is restricted by the lever release boss 41e. Accordingly, in the state where the lever 55 is retained, the member other than the lever 55 in the preceding tape placement unit 5A moves forward, and the unit engagement protrusion 572 of the preceding tape placement unit 5A is pulled out (withdrawn from the engagement position Lg) forward from the feeder engagement hole 412. The gap Δ between the distal end of the long hole 551a and the bolt 56 is set to be equal to or greater than the distance that the unit engagement protrusion 572 moves to remove the unit engagement protrusion 572 from the feeder engagement hole 412.

As described above, when the subsequent tape placing unit 5B moves in the feeding direction Df, the preceding tape placing unit 5A is pushed out by the subsequent tape placing unit 5B, and the unit engaging protrusion 572 of the preceding tape placing unit 5A is withdrawn from the engaging position Lg forward of the feeding direction Df and pulled out from the feeder engaging hole 412 (fig. 28A and 28B). As a result, the preceding tape placement unit 5A is separated from the tray 411 of the tape feeder 4 and falls down by its own weight (fig. 28A to 30B). Specifically, when the unit engagement protrusion 572 of the preceding tape placement unit 5A is pulled out from the feeder engagement hole 412 toward the front in the feeding direction Df, the rear end of the preceding tape placement unit 5A falls down while rotating about the support boss 4e in a state where the support slit 5e of the preceding tape placement unit 5A is engaged with the support boss 4e (fig. 28B). Then, as the preceding tape placing unit 5A falls down, the support slit 5e of the preceding tape placing unit 5A is disengaged from the support boss 4e of the tape feeder 4. In this way, the preceding tape placement unit 5A is detached from the tape feeder 4. In addition, the detached preceding tape placement unit 5A is in the state of fig. 12B.

As described above, the feeder main body 41 of the tape feeder 4 has the lever release boss 41e, and the abutment portion 553d located at the front end of the tape cover 553 of the advanced tape placement unit 5A attached to the feeder main body 41 abuts against the lever release boss 41 e. On the other hand, as described above, the lever 55 is attached to the base frame 51 by the bolt 56 inserted into the long hole 551 a. Therefore, in the above-described process in which the preceding tape placing unit 5A is pushed out by the following tape placing unit 5B, in a state in which the movement of the lever 55 of the preceding tape placing unit 5A in the feeding direction Df is impeded by the feeder main body 41, the (member other than the lever 55 of the) preceding tape placing unit 5A is moved in the feeding direction Df, and the tape restraining state of the preceding tape placing unit 5A is continuously released.

Next, as shown in fig. 31, the unit engagement protrusion 572 of the subsequent tape placement unit 5B enters the engagement position Lg from the rear in the feeding direction Df. At this time, the subsequent tape placing unit 5B maintains the tape restraining state until the subsequent tape placing unit 5B is mounted to the tray 411 of the tape feeder 4. On the other hand, as shown in fig. 31, as the unit engagement protrusion 572 of the subsequent tape placement unit 5B enters the engagement position Lg, the abutment portion 553d of the tape cover 553 of the lever 55 provided in the subsequent tape placement unit 5B abuts against the lever release boss 41e of the feeder main body 41. Then, in a state where the movement of the lever 55 in the feeding direction Df is blocked by the feeder main body 41, (the members other than the lever 55) of the tape placing unit 5 are moved in the feeding direction Df. Accordingly, the lever 55 is pushed out relatively from the contact position Lc to the retracted position Le2 by the feeder main body 41, and the front projection 551B of the feeder main body 41 is disengaged from the restricting plate 554 (fig. 32B). As a result, the lever 55 is rotated upward by the biasing force of the compression coil spring 53, the tape restraining state is released, the component tape TP is pressed against the sprocket 44, and the hole of the component tape TP is fitted with the tooth of the sprocket 44, and the component tape TP can be fed in the feeding direction Df. In this way, the unit engagement protrusion 572 of the subsequent tape placement unit 5B engages with the feeder engagement hole 412 at the engagement position Lg, and the subsequent tape placement unit 5B is attached to the tray 411 (fig. 32A and 32B) of the tape feeder 4, whereby the unit replacement is completed. Then, as shown in fig. 32C, when the component replenishment carriage 8 is pulled out from the feeder attachment carriage 7 to the rear in the feeding direction Df, the subsequent tape placement unit 5B attached to the tape feeder 4 is detached from the component replenishment carriage 8 and retained in the tape feeder 4.

Fig. 33 is a block diagram showing a configuration of a component mounting system including the component mounter. In fig. 33, the component replenishment carriage 8 detached from the component supply section 25 of the component mounter 1 is shown separately from the component mounter 1. The component mounting system 9 includes the component mounter 1 and the component replenishment support device 91. The electrical structure of the component mounting system 9 will be mainly described with reference to fig. 33.

As shown in fig. 33, the tape feeder 4 has a tape sensor 491. The tape sensor 491 detects the component supply tape TP attached to an attachment portion 441 (fig. 2 and 3) between the tape placement unit 5 engaged with the bracket 411 and the sprocket 44. The feeder mount carriage 7 has a reader 78 for reading the replenishment carriage ID86 attached to the component replenishment carriage 8. The replenishment carriage ID86 is composed of a bar code and is unique, and can be used to individually identify the component replenishment carriage 8 to which the replenishment carriage ID86 is attached. The reader 78 is attached to a position facing the replenishment carriage ID86 of the component replenishment carriage 8 in a state where the component replenishment carriage 8 is attached to the feeder attachment carriage 7. That is, the reader 78 reads the replenishment carriage ID86 of the component replenishment carriage 8 attached to the feeder-attaching carriage 7 by scanning the replenishment carriage ID86. The structures of the replenishment trolley ID86 and the reader 78 are not limited to this example, and may be, for example, RFID (Radio Frequency Identifier: radio frequency identifier).

The component mounter 1 further includes a control unit 101, a storage unit 102, and a communication unit 103. The control unit 101 is a processor including a CPU (Central Processing Unit: central processing unit), for example, and executes overall control of the component mounter 1. The storage unit 102 is configured by, for example, an HDD (Hard Disk Drive), and stores component feeder information Ipf described later. The communication unit 103 performs communication between the component mounter 1 and the component replenishment support device 91. Similarly, the component replenishment carriage 8 is also provided with a communication unit 803 for performing communication between the component replenishment carriage 8 and the component replenishment support device 91.

The component replenishment support device 91 includes an arithmetic unit 911, a storage unit 912, a communication unit 913, and a user interface 914, and is configured by, for example, a personal computer. The computing unit 911 is a processor composed of, for example, a CPU, and performs the computing function of the component replenishment support device 91. The storage unit 912 is configured by, for example, an HDD, and stores component correspondence information Ip and feeder correspondence information If described later. The communication section 913 performs communication with the control section 101 of the component mounter 1 and communication with the communication section 803 of the component replenishment carriage 8. The user interface 914 is constituted by an input device such as a mouse or a keyboard, and a display device such as a display. The component replenishment support device 91 further includes a reader 915 that reads the feeder ID421, the reel ID63, the component ID64, and the like. The specific configuration of the component replenishment support device 91 is not limited to this example, and may be a portable tablet terminal, for example.

The component replenishment support device 91 provided in the component mounting system 9 functions to support replenishment of components to the tape feeder 4 by using the component replenishment carriage 8. In particular, the component replenishment support device 91 can support the operation of collectively replenishing components to the plurality of replenishment target tape feeders 4 to be subjected to component replenishment among the plurality of tape feeders 4 of the component supply unit 25. This will be described below.

As shown in step S13 of fig. 2, when loading of the component supply tape TP attached to the attachment portion 441 of the tape feeder 4 is performed and the tip end of the component supply tape TP is fed out to the sprocket 44, unit replacement (attachment operation) shown in fig. 24 to 32C can be performed. In the present specification, a case where the component tape TP for component feeding is mounted to the mounting portion 441 after the component tape TP for component feeding is mounted by such replacement of the unit is referred to as a preset period, and a period from a time point when the component tape TP mounted to the mounting portion 441 of the tape feeder 4 is mounted to engage with the sprocket 44 by being mounted until the component tape TP runs out of components is referred to as a presettable period.

When all of the tape feeders 4 mounted on one component feeder 25 reach the presettable period, the component supply reels 6 around which the component supply tapes TP for component supply by the tape feeders 4 are wound are transferred from the reel mounting table 85 of the component replenishment carriage 8 to the reel holding portion 75 of the feeder mounting carriage 7, whereby the component replenishment carriage 8 can be detached from the feeder mounting carriage 7. The tape placement unit 5 engaged with the tape feeder 4 is disengaged from the unit insertion groove 831 of the component replenishment carriage 8 and is stopped in a state engaged with the tape feeder 4 in association with the removal of the component replenishment carriage 8. As a result, for example, a state of the feeder attachment carriage 7 before the component replenishment carriage 8 is attached, that is, a state in which the component supply reel 6 around which the component supply tape TP attached to the attachment portion 441 of the tape feeder 4 is wound is held by the feeder attachment carriage 7 is realized as shown in fig. 24.

Therefore, the worker can perform component replenishment (total replenishment) at one time by simultaneously performing the unit replacement shown in fig. 24 to 32C for these tape feeders 4 which reach the presettable period. In particular, in the present embodiment, the component replenishment support device 91 supports the component replenishment so that the operator can prepare the component replenishment carriage 8 for the component replenishment before the component replenishment.

Fig. 34 is a flowchart showing an example of the component replenishment support performed by the component replenishment support apparatus. The flowchart is executed by the operation of the operation unit 911 of the component replenishment support device 91.

In step S101, the computing unit 911 obtains a production plan for producing the board B (component mounting board) on which the components are mounted using the component mounter 1, and stores the production plan in the storage unit 912. The production plan is acquired by, for example, an input operation performed by an operator via the user interface 914. Specifically, the production plan indicates the types of substrates to be produced in association with the number of sheets. The computing unit 911 obtains the progress status (production progress) of the production plan from the component mounter 1 (step S102). That is, the type and number of substrates that have been produced at the current time in the production plan, in other words, the type and number of substrates that have been produced at the current time, are obtained as progress status. The computing unit 911 acquires substrate data for controlling the component mounter 1 based on the production plan from the component mounter 1 (step S103). The substrate data is a program for controlling the component mounter 1 so that components are mounted onto the substrate B in the order according to the production plan, and the control unit 101 of the component mounter 1 controls operations of the conveyor 12, the tape feeder 4, the mounting head 31, and the like based on the substrate data, thereby mounting components onto the substrate B.

In step S104, the supply number Nc for identifying the plurality of (4 in the example of fig. 1) component feeders 25 of the component mounter 1 is reset to 0, and in step S105, the supply number Nc is incremented. In step S106, the feeder number Nf of each tape feeder 4 attached to the component feeder 25 corresponding to the current feeder number Nc (nc=1) is identified and reset to 0, and in step S107, the feeder number Nf is incremented.

Then, in step S108, it is determined whether or not the tape feeder 4 of the feeder number Nf in the component feeder 25 of the feeder number Nc, that is, the tape feeder 4 to be set is the self-charging type tape feeder 4. When the tape feeder 4 to be set is of the automatic loading type (yes in step S108), the time until the tape feeder 4 to be set reaches the preset period is calculated based on the production progress and the substrate data (step S109), and the process proceeds to step S110. Specifically, the time is calculated from the result of simulation of the case where the tape feeder 4 as the object is fed with the components based on the substrate data, starting from the current production progress.

That is, as illustrated in fig. 9 and the like of WO2018/135446, the production plan obtained by the operation unit 911 indicates the number of production sheets and the production order of the substrates for each type of substrate, and indicates the number of components required for producing one substrate of that type for each component name. The calculation unit 911 can obtain the cycle time, which is the time required for the component mounter 1 to mount all components on one substrate when the production plan is executed according to the substrate data. The computing unit 911 also stores the remaining number of components in the component supply tape TP held in the reel ID63 in the storage unit 912 in association with the reel ID 63. Therefore, the timing at which one component supply tape TP runs out of components and the next component supply tape TP is loaded, that is, the start time of the preset period can be calculated from the remaining number of components in one component supply tape TP to be used for component supply, the number of components mounted on one substrate, and the cycle time of the component.

On the other hand, when the tape feeder 4 to be set is not of the automatic loading type (no in step S108), the process proceeds to step S110 without going through step S109.

In step S110, the time until the remaining number is warned is calculated. Specifically, the number of components (i.e., the number of components remaining) stored in all the component supply tapes TP mounted on the tape feeders 4 to be subjected to the process is calculated based on the production progress and the substrate data as described above, and the time to reach the warning remaining number is calculated. The warning remaining number provides a timing for warning the operator, and the component mounter 1 reports a warning to the operator when the component remaining number of the tape feeder 4 reaches the warning remaining number.

In step S111, the time until the remaining number stops is calculated. Specifically, the time for the remaining number of components of the tape feeder 4 to be subjected to the calculation to reach the stop remaining number is calculated based on the production progress and the substrate data as described above. In addition, the stop remaining number is a value smaller than the warning remaining number, and timing to stop the component supply by the tape feeder 4 is provided, and when the component remaining number of the tape feeder 4 reaches the stop remaining number, the component mounter 1 stops the component supply by the tape feeder 4.

In step S112, the time until the feeder shoe carriage 7 is replaced is calculated. That is, when the type of the substrate to be produced according to the production schedule is changed, the arrangement is changed. Thus, the time until the arrangement change is calculated.

In step S113, it is checked whether or not the feeder number Nf reaches the maximum value Nfx (corresponding to the number of tape feeders 4 in the supply unit number Nc), and steps S107 to S112 are performed until the feeder number Nf reaches the maximum value Nfx. Thus, steps S107 to S112 are performed for all the tape feeders 4 of the component supply unit 25 of the supply unit number Nc.

In step S114, it is checked whether or not the supply unit number Nc reaches the maximum value Ncx (corresponding to the number of supply unit numbers Nc in the component mounter 1), and steps S105 to S113 are performed until the supply unit number Nc reaches the maximum value Ncx. Thus, steps S105 to S113 are performed for all the component supply units 25 of the component mounter 1.

Incidentally, a component mounter 1 is described here. However, in a production line in which a plurality of component mounters 1 are arranged in series, when the substrate B is sequentially fed to the plurality of component mounters 1 and the component mounters 1 perform component mounting on the substrate B, steps S102 to S114 are performed for the plurality of component mounters 1, respectively. In addition, when each component mounter 1 has a plurality of lanes (for example, two lanes), steps S102 to S114 are performed for each of the plurality of lanes. If a plurality of production lines are provided, steps S101 to S114 are executed for each of the plurality of production lines.

In step S115, the computing unit 911 calculates the schedule based on the results of the operations in steps S101 to S114. The schedule indicates the occurrence time of each event of the tape feeders 4 calculated in steps S109 to S112 for each tape feeder 4, and indicates, for example, a presettable period of the tape feeders 4 for each tape feeder 4 to be automatically loaded.

In step S116, the computing unit 911 calculates the replenishment timing of the components to the tape feeder 4. In particular, the computing unit 911 determines the timing at which the above-described one-time replenishment can be performed for each of the plurality of component supply units 25. Specifically, the period in which the presettable period of each of the plurality of tape feeders 4 included in the component supply unit 25 is repeated is calculated as a collectively-feedable period (replenishment timing). The one-time replenishment period corresponds to a period in which all the component supply reels 6 held by the component replenishment carriage 8 of the feeder mount carriage 7 mounted to the component supply section 25 are transferred from the component replenishment carriage 8 to the feeder mount carriage 7, and the component replenishment carriage 8 can be detached from the feeder mount carriage 7. The calculation of the collectively available replenishment period is performed for each of the plurality of component supply units 25.

Here, the plurality of component supply units 25 correspond to the plurality of component supply units 25 included in the object of the component replenishment management support. For example, in the case where one component mounter 1 is targeted, the plurality of component feeders 25 corresponds to all the component feeders 25 included in the component mounter 1, and in the case where a production line in which the plurality of component mounters 1 are arranged in series is targeted, the plurality of component feeders 25 corresponds to all the component feeders 25 included in the production line.

In step S117, the components fed to the tape feeder 4 by the lump-sum feeding executed during the lump-sum feeding enabled period are determined. Specifically, the replenishment target tape feeder 4 to be a target of component replenishment among the plurality of tape feeders 4 of the automatic loading type provided in the component supply section 25 is specified. For example, when the number of components stored in the component supply tape TP mounted on the tape feeder 4 is equal to or greater than the number of components to be supplied by the tape feeder 4 based on the production schedule when the presettable period is reached, the components do not need to be supplied to the tape feeder 4. Therefore, the tape feeder 4 is excluded from the objects to be replenished with components. The replenishment elements for the thus-determined plurality of replenishment target tape feeders 4 are determined.

In step S118, the result of the determination in step S117 is displayed as a replenishment list T on the display of the user interface 914. Fig. 35 is a diagram showing an example of the replenishment list T. In the replenishment list T, the total replenishment period is indicated by a start time and an end time (for example, ts1 to te 1). The replenishment list T also shows the component supply unit 25 that can be replenished together in the one-time replenishment period, and the components (P1 a, P1b … …, etc.) that are supplied to the respective feeders 4a, 4b, 4c, 4d, … … of the component supply unit 25 by one-time replenishment. The components P1a, P1b, … … are displayed for each of the replenishment target tape feeders 4 in the plurality of tape feeders 4 included in the target component supply unit 25, and "-" indicating that no component should be replenished is displayed for the tape feeders 4 other than the replenishment target tape feeder 4.

In the component mounting system 9 including the component replenishment support device 91, an operator can perform, at a work place separated from the component supply unit 25 of the component mounter 1, one-time replenishment preparation of the component supply reel 6 (component supply tape TP) corresponding to the component to be replenished by the one-time replenishment after the one-time replenishment, while referring to the replenishment list T of fig. 35, on the component replenishment carriage 8.

Fig. 36 is a flowchart showing an example of the preparation for the total replenishment. The flowchart is executed by the operation of the operation unit 911 of the component replenishment support device 91. In step S201, whether or not there is any designation for replenishment is checked. Specifically, the operator can designate one of the plurality of available one-time replenishment periods shown in the replenishment list T displayed in the user interface 914, and the computing unit 911 determines that preparation for one-time replenishment corresponding to the designated available one-time replenishment period has started.

In step S202, it is checked whether the replenishment trolley ID86 is acquired. Specifically, when the operator reads the replenishment trolley ID86 of the component replenishment trolley 8 for which the collective replenishment preparation is performed by the reader 915, the computing unit 911 determines that the replenishment trolley ID86 read by the reader 915 has been acquired (yes in step S202). Thus, the computing unit 911 can identify the component replenishment trolley 8, which is the object of the replenishment preparation together, by using the replenishment trolley ID86.

Next, the operator takes out the component supply reel 6 to be mounted on the reel mounting table 85 of the component replenishment carriage 8 in the component replenishment preparation from the component library while referring to the replenishment list T, and reads the component ID64 and the reel ID63 attached to the component supply reel 6 by the reader 915. The component ID64 and the reel ID63 read by the reader 915 in this way are acquired by the arithmetic unit 911 (yes in steps S203 and S204).

The operator holds the front end portion of the component supply tape TP pulled out from the component supply reel 6 in the tape placement unit 5, and attaches the tape placement unit 5 to the unit insertion slot 831 of the component replenishment carriage 8. At this time, the operator refers to the replenishment list T and installs the tape placement unit 5 in the unit insertion groove 831 corresponding to the placement position S of the tape feeder 4 to which the components in the component supply tape TP should be replenished. Upon receiving this signal, the communication unit 803 of the component replenishment carriage 8 transmits the placement position S corresponding to the unit socket 831 in which the tape placement unit 5 is mounted to the communication unit 913 of the component replenishment support device 91, and the calculation unit 911 acquires the placement position S received by the communication unit 913 (yes in step S205).

When all the information of the component ID64, the reel ID63, and the placement position S is acquired (yes in step S206), it is determined whether or not the combination thereof matches the substrate data based on the production plan (step S207). Specifically, since the component ID64 to be placed on the tape feeder 4 is set for each placement position S of the tape feeder 4 in the substrate data, it is checked whether or not the component ID64 of the placement position S indicated by the substrate data matches the component ID64 corresponding to the reel ID63 mounted on the placement position S of the feeder mount carriage 7. For example, when the worker mistakes the unit insertion slot 831 in which the tape placement unit 5 is mounted, the combination thereof does not match the substrate data, and the determination in step S207 is no. As a result, a warning that the combination does not match the substrate data is displayed on the user interface 914 (step S208), and the flow advances to step S210. On the other hand, when the combination matches the substrate data (yes in step S207), the computing unit 911 generates the element correspondence information Ip for associating them with each other, and stores the information in the storage unit 912 (step S209), and the flow proceeds to step S210.

Incidentally, in the case where the combination of the component ID64, the reel ID63, and the placement position S matches the substrate data based on the production plan, the operation unit 911 may further perform a replenishment list matching determination in which it is determined whether or not the replenishment list T generated based on the past production progress acquired in step S102 matches the current production progress. That is, when the production is interrupted due to an error or the like in the middle, there is a possibility that the collectively replenishment is not possible in the collectively replenishment period calculated from the progress situation (step S102) obtained for creating the replenishment list T, and the presetting cannot be performed for a part of the tape feeders 4 that are collectively replenishment targets. Accordingly, in the total replenishment-enabled period, the total replenishment may be performed in accordance with the replenishment list T, that is, if the replenishment list T matches the current production progress, the determination may be yes in step S207, and if they do not match, the determination may be no in step S207.

In step S210, it is determined whether or not the one-time replenishment preparation is completed. Specifically, it is determined whether or not the tape placement unit 5 is mounted in all the unit slots 831 corresponding to the placement positions S of all the replenishment target tape feeders 4 that are the targets of the one-time replenishment designated in step S201. In the case where there is a unit slot 831 in which the tape placement unit 5 is not mounted, it is determined that the one-replenishment preparation is not completed (no in step S210), and the flow returns to step S203. On the other hand, when the attachment of the tape placing unit 5 to all the unit slots 831 is confirmed, it is determined that the one-time replenishment preparation is completed (yes in step S210).

In this way, when the preparation for the total replenishment is completed, the element correspondence information Ip shown in fig. 37 is stored in the storage unit 912. Here, fig. 37 is a diagram schematically showing an example of the element correspondence information. In fig. 37, the placement positions S2, S4, S5 hatched with diagonal lines correspond to the placement position S of the replenishment subject tape feeder 4. In this way, for each placement position S of the replenishment subject tape feeder 4, the component correspondence information Ip is generated and stored which associates the placement position S with the component ID64 and the reel ID63 of the component supply tape TP on the tape placement unit 5 corresponding to the placement position S.

The component replenishment carriage 8, which has completed the collective replenishment preparation, is mounted on the feeder mounting carriage 7 of the component supply unit 25 to be subjected to the replenishment. In the preparation work for the feeder-mounting cart 7 performed earlier than the one-time replenishment preparation, the feeder correspondence information If of fig. 38 is generated for the feeder-mounting cart 7 and stored in the storage unit 912 in advance. Here, fig. 38 is a diagram schematically showing the content of feeder correspondence information. As shown in fig. 38, the feeder correspondence information If indicates the placement position S in the feeder-mounting carriage 7 and the feeder ID421 of the tape feeder 4 attached to the placement position S, and the feeder correspondence information If is generated and stored for each of the plurality of placement positions S of the feeder-mounting carriage 7.

When the component replenishment carriage 8 is attached to the feeder attachment carriage 7 of the component supply unit 25, the plurality of tape placement units 5 attached to the component replenishment carriage 8 are engaged with the plurality of replenishment target tape feeders 4, respectively, in the manner shown in fig. 24 to 32C. As a result, the component supply tape TP held by the tape placement units 5 is mounted on the plurality of replenishment target tape feeders 4.

In addition, with the attachment of the component replenishment carriage 8 to the feeder attachment carriage 7, the component correspondence information Ip related to the component replenishment carriage 8 and the feeder correspondence information If related to the feeder attachment carriage 7 are integrated (data combination), and component feeder information Ipf (fig. 39) is generated. Fig. 39 is a diagram schematically showing the content of the component feeder information. As shown in fig. 39, the component feeder information Ipf is represented by associating the feeder ID421, the component ID64, and the reel ID63, which correspond to the same placement position S, with each of the plurality of replenishment target tape feeders 4.

The above-described replenishment list matching determination may be performed before the component replenishment carriage 8 is mounted on the feeder mounting carriage 7 of the component feeder 25. That is, it is possible to perform replenishment list matching judgment with respect to the replenishment list T referred to in preparation for the component replenishment carriage 8 to be mounted later, and to permit mounting of the component replenishment carriage 8 when the replenishment list is matched, and to prohibit mounting of the component replenishment carriage 8 and to give a warning to the operator when the replenishment list is not matched.

In the embodiment described above, in the component mounter 1, the plurality of tape feeders 4 each having the mounting portion 441 are arranged in the component supply portion 25, and the plurality of tape feeders 4 supply components stored in the component supply tape TP mounted to the respective mounting portions 441. In addition, the component mounting machine 1 can be efficiently supplied with components. Specifically, the component replenishment carriage 8 is used for replenishing components to the tape feeder 4 of the component mounter 1. The component replenishment carriage 8 has a plurality of unit insertion grooves 831 corresponding to the plurality of tape feeders 4, respectively. Further, by mounting the component replenishment carriage 8 to the component supply section 25 of the component mounter 1, the component supply tapes TP held in the unit slots 831 corresponding to (in other words, located at the same placement position S) respectively to the plurality of replenishment target tape feeders 4 among the plurality of tape feeders 4 can be collectively mounted to the mounting locations 441 (collectively replenished) of the plurality of replenishment target tape feeders 4. In particular, based on the production plan, a replenishment list T (preparation plan) indicating the component supply tapes TP to be held in the unit slots 831 of the component replenishment carriage 8 for preparation of the collective replenishment is calculated. Accordingly, in parallel with the component mounting by the component mounter 1, the component supply tape TP is prepared in the component replenishment carriage 8 based on the production plan, and the component supply tape TP can be replenished to the plurality of replenishment target tape feeders 4 by executing the replenishment at once at the timing when the replenishment is required. In this way, in the present embodiment, component replenishment to the tape feeder 4 can be efficiently performed.

Further, the system is provided with a user interface 914 for displaying the replenishment list T to the operator. In this configuration, the operator can prepare the component supply tape TP on the component supply carriage 8 while checking the supply list T displayed on the user interface 914.

The component tape TP is provided with component information (reel ID63 and component ID 64) related to the components stored in the component tape TP. On the other hand, when the component correspondence information Ip indicating the correspondence between the component slots 831 and the component information of the component tape TP held in the respective component slots 831 does not match the production plan (no in step S207), the computing unit 911 gives a warning to the operator (step S208). In this configuration, when an error occurs in the preparation work for preparing the component supply tape TP for the component replenishment carriage 8, a warning can be given to the operator.

The tape feeder 4 is provided with feeder information (feeder ID 421) related to the tape feeder 4. In contrast, the computing unit 911 obtains component correspondence information Ip indicating the correspondence between the component slots 831 and the component information of the component tape TP held in the component slots 831, and feeder correspondence information If indicating the correspondence between the component slots 831 and the feeder information of the tape feeders 4 corresponding to the component slots 831. When the component replenishment carriage 8 is mounted on the feeder mounting carriage 7 of the component feeder 25, component feeder information Ipf is generated for the component feeder 4 and the unit slot 831 corresponding to each other (i.e., corresponding to the same placement position S), in which component information of the component feeding tape TP held in the unit slot 831 is expressed in association with feeder information of the tape feeder 4. In this configuration, the component feeder information Ipf is generated in association with the attachment of the component replenishment carriage 8 to the component supply section 25. Therefore, the arrangement state of the component supply tape TP after component replenishment with respect to the tape feeder 4 can be accurately grasped from the component feeder information Ipf.

Further, both the preceding tape placement unit 5A and the following tape placement unit 5B can be engaged with and disengaged from the tape feeder 4. Then, one tape placement unit 5 of the preceding tape placement unit 5A and the subsequent tape placement unit 5B is engaged with the tape feeder 4, and the component supply tape TP held by the one tape placement unit 5 is mounted on the mounting portion 441 of the tape feeder 4. Further, the subsequent tape placing unit 5B can be mounted in the unit slot 831 of the component replenishment carriage 8, and the subsequent tape placing unit 5B is mounted in the unit slot 831, whereby the component supply tape TP held in the subsequent tape placing unit 5B is held in the unit slot 831. When the component replenishment carriage 8 having the subsequent tape placement unit 5B attached to the component supply section 25 is mounted in the unit insertion groove 831 corresponding to the replenishment target tape feeder 4 in a state in which the preceding tape placement unit 5A is engaged with the replenishment target tape feeder 4, the subsequent tape placement unit 5B is engaged with the replenishment target tape feeder 4 while pushing out the preceding tape placement unit 5A to disengage the preceding tape placement unit 5A from the replenishment target tape feeder 4. In this configuration, by the operation of attaching the component replenishment carriage 8 to the component supply section 25, the tape placement unit 5 attached to the replenishment target tape feeder 4 can be replaced with the subsequent tape placement unit 5B from the preceding tape placement unit 5A, and the component supply tape TP held by the subsequent tape placement unit 5B can be easily attached to the replenishment target tape feeder 4.

Thus, in the present embodiment, the component mounting system 9 corresponds to an example of the "component mounting system" of the present invention, the component mounter 1 corresponds to an example of the "component mounting machine" of the present invention, the component supply unit 25 corresponds to an example of the "component supply unit" of the present invention, the tape feeder 4 corresponds to an example of the "feeder" of the present invention, the mounting portion 441 corresponds to an example of the "mounting portion" of the present invention, the mounting head 31 corresponds to an example of the "mounting head" of the present invention, the board B corresponds to an example of the "board" of the present invention, the component replenishment carriage 8 corresponds to an example of the "replenishment carriage" of the present invention, the unit slot 831 corresponds to an example of the "holding unit" of the present invention, the component replenishment support device 91 corresponds to an example of the "component support device" of the present invention, the operation unit 911 corresponds to an example of the "operation unit" of the present invention, the storage unit 912 corresponds to an example of the "storage unit" of the present invention, the user interface 914 corresponds to an example of the "preparation plan display unit" of the present invention, the replenishment list T corresponds to an example of the "preparation plan" of the present invention, the IDs of the "preparation plan ID and the component 63 corresponds to an example of the information of the reel 421 of the present invention.

The present invention is not limited to the above-described embodiments, and various modifications can be made to the above-described embodiments without departing from the gist thereof. Fig. 40 is a flowchart showing a modification of the co-feeding. The flowchart is executed by the operation of the operation unit 911 of the component replenishment support device 91.

In step S301, it is checked whether or not the replenishment carriage ID86 of the component replenishment carriage 8 is acquired by the reader 78 of the feeder attachment carriage 7 as the component replenishment carriage 8 is attached to the feeder attachment carriage 7 of the component supply section 25. When the replenishment carriage ID86 is acquired (yes in step S301), it is determined whether or not the replenishment carriage ID86 is appropriate, that is, whether or not the replenishment carriage ID86 is the replenishment carriage ID86 of the component replenishment carriage 8 to be mounted in the component supply unit 25 for the purpose of replenishment together (step S302).

When the replenishment carriage ID86 is not appropriate (no in step S302), the user interface 914 displays a warning indicating that the combination of the component replenishment carriage 8 and the component supply section 25 is not appropriate (step S303).

When the replenishment carriage ID86 is appropriate (yes in step S302), the tape sensor 491 determines whether or not the component supply tape TP held by the component replenishment carriage 8 is attached to the attachment portion 441 of the tape feeder 4 to which the tape sensor 491 belongs. That is, when the unit replacement is performed, the component supply tape TP is dropped from the mounting portion 441, and then the subsequent component supply tape TP enters the mounting portion 441, and therefore, the presence of the component supply tape TP in the mounting portion 441 is changed in the order of the component supply tape TP, the non-component supply tape TP, and the component supply tape TP. Accordingly, the tape sensor 491 can confirm the attachment of the component supply tape TP held by the component replenishment carriage 8 to the attachment site 441 based on the change.

This mounting confirmation is individually performed in each of the plurality of tape feeders 4 held in the feeder-mounting carriage 7. Then, with respect to the tape feeder 4 in which the mounting of the component supply tape TP is detected, it is checked whether or not the detection portion is appropriate, that is, whether or not the placement position S of the tape feeder 4 coincides with the placement position S of the replenishment target tape feeder 4 (step S305). The data is integrated with the tape feeder 4 determined to be appropriate (yes) for the detection portion in step S305 as shown in fig. 39, and the component feeder information Ipf is generated (step S306). On the other hand, the user interface 914 displays a warning that the tape feeder 4 is not appropriate as to the mounting destination of the component supply tape TP held in the component replenishment carriage 8, with respect to the tape feeder 4 whose detection portion is determined to be inappropriate in step S305, without integrating the data (step S303).

In step S307, it is checked whether or not the mounting of the component supply tape TP held by the component replenishment carriage 8 is detected for all of the replenishment target tape feeders 4 that are collectively replenished. When the mounting of the component supply tape TP is not detected for all the replenishment target tape feeders 4 (no in step S307), the user interface 914 displays that there is a replenishment target tape feeder 4 for which no component supply tape TP is present.

In this modification, the plurality of tape feeders 4 include tape sensors 491 that detect the attachment of the component supply tapes TP to the respective attachment sites 441. In contrast, when the component replenishment carriage 8 is mounted on the component supply unit 25, the computing unit 911 generates the component feeder information Ipf for the replenishment target tape feeder 4 in which the mounting of the component supply tape TP to the mounting portion 441 is detected, among the plurality of replenishment target tape feeders 4, and does not generate the component feeder information Ipf for the replenishment target tape feeder 4 in which the mounting of the component supply tape TP to the mounting portion 441 is not detected (steps S304 to S306). In this configuration, for example, when the component supply tape TP fails to be mounted on the replenishment target tape feeder 4 due to a failure such as detachment of the tape placement unit 5 from the component replenishment carriage 8 during conveyance of the component replenishment carriage 8, appropriate component feeder information Ipf reflecting the failure can be generated.

When it is confirmed that the replenishment belt feeder 4 to which the component supply tape TP is not disposed to the mounting portion 441 is present after the component replenishment carriage 8 is mounted to the component supply portion 25 (no in step S307), the computing portion 911 issues a warning to the operator (step S303). In this configuration, for example, when the component supply tape TP fails to be mounted on the replenishment target tape feeder 4 due to a trouble in the transportation of the component replenishment carriage 8, a warning can be given to the operator.

When the component supply tape TP is detected to be mounted to the mounting portion 441 of the tape feeder 4 other than the replenishment target tape feeder 4 among the plurality of tape feeders 4 along with the mounting of the component replenishment carriage 8 to the component supply unit 25 (step S305), the computing unit 911 gives a warning to the operator (step S303). In this configuration, when the component supply tape TP is erroneously attached to the tape feeder 4 different from the replenishment target tape feeder 4, a warning can be given to the operator.

The component replenishment carriage 8 is attached with a replenishment carriage ID86 for identifying the component replenishment carriage 8, and the feeder mount carriage 7 of the component feeder 25 has a reader 78 for reading the replenishment carriage ID86 attached to the component replenishment carriage 8 mounted on the feeder mount carriage 7. On the other hand, when the combination of the component replenishment carriage 8 and the component supply unit 25 indicated by the replenishment carriage ID86 read by the reader 78 is not appropriate (in the case of no in step S302), the calculation unit 911 gives a warning to the operator (step S303). In this configuration, the component replenishment carriage 8 can be prevented from being attached to the wrong component supply unit 25.

Further, modifications different from the modification examples shown here can be added to the above-described embodiments. For example, the feeder to be fed together is not limited to the belt feeder, and may be a tray feeder as shown in fig. 41. Fig. 41 is a diagram schematically showing a structure of a tray feeder to be collectively replenished.

As shown in fig. 41, the component mounter 120 mounts components mounted on a tray 121 on a board B, and has a plurality of shelves 123 (component supply sections) stacked in the Z direction. The plurality of shelves 123 corresponds to a "feeder", and each shelf 123 has a bottom surface 123a to which the tray 121 is attached. Each rack 123 receives and delivers the tray 121 from the bottom surface 123a to a tray drawing member (not shown), and the mounting head mounts the components on the tray 121 supplied from the rack 123 via the tray drawing member to the substrate B. The component mounter 120 further includes a tray collection unit 125 for collecting empty trays 121 below the plurality of racks 123.

On the other hand, the component replenishment carriage 8 has a plurality of tray insertion grooves 87 corresponding to the plurality of racks 123. Then, in step S401, the component replenishment carriage 8 holding the tray 121 in each tray slot 87 corresponding to each replenishment target shelf 123 (empty shelf 123) among the plurality of shelves 123 is transported toward the component mounter 120. Then, the component replenishment carriage 8 reaches the component mounter 120 (step S402), and the tray pushing members 871 provided in the respective tray insertion grooves 87 are moved to the component mounter 120 side (step S403), whereby the component replenishment carriage 8 is mounted to the component supply section (i.e., the plurality of shelves 123) of the component mounter 1. Thus, the tray slots 87 are mounted on the plurality of replenishment object shelves 123, respectively, and the replenishment is completed at once. The above embodiment can be similarly applied to such a configuration.

Further, a modified example in which the operation unit 911 repeatedly executes the component replenishment support shown in fig. 34 is also considered. In this modification, for example, each time the execution time set at a predetermined interval is reached, the acquisition of the production plan, the acquisition of the production progress, and the acquisition of the substrate data are executed (steps S101, S102, S103), and the replenishment list T is generated based on the real-time production progress at the execution time.

Further, the timing at which the one-time replenishment is performed need not be represented as a one-time replenishment-enabled period having a width in time. That is, as the timing of performing the collective replenishment, the time at which the collective replenishment is possible (for example, the start time of the collective replenishment period) can be displayed to the operator. In this case, as shown in fig. 42, the replenishment list T may be deformed.

Fig. 42 is a diagram schematically showing a modification of the replenishment list. In the replenishment list T of fig. 42, whether or not the replenishment can be performed at the time of being possible to perform the replenishment together, whether or not the replenishment is necessary, and whether or not the replenishment is performed (no use/execution/impossible) are shown for each of the tape feeders 4 placed at the placement positions S1, S2, … …. Here, the term "no replenishment need be performed (" replenishment is performed "in the column" no need "), which means that although the target tape feeder 4 can be pre-set, the production plan can be completed by using the components remaining in the component supply tape TP attached to the tape feeder 4, and thus the components do not need to be replenished to the tape feeder 4, and thus the component replenishment to the tape feeder 4 does not need to be performed. The execution of replenishment ("replenishment execution" is "execution" in the column) means that the tape feeder 4 to be subjected to replenishment can execute the replenishment, and the production plan cannot be completed by the components remaining in the component supply tape TP attached to the tape feeder 4, and the replenishment of components to the tape feeder 4 is required to continue the production plan, so that the replenishment of components to the tape feeder 4 is executed. The inability to supply ("the" execution of supply "is" unable ") means that the production plan cannot be completed by the components remaining in the component supply tape TP mounted on the target tape feeder 4, and that the components need to be supplied to the tape feeder 4 in order to continue the production plan, but the presetting to the tape feeder 4 cannot be executed, and thus the component supply to the tape feeder 4 cannot be executed.

According to this example of the replenishment list T, at the time of the replenishment together, the tape feeder 4 at the placement position S1 cannot be preset, and replenishment of components is not required. As a result, it is not necessary to perform replenishment at the time when replenishment is possible for the tape feeder 4 at the placement position S1. The tape feeder 4 at the placement position S2 can be preset at the same time of replenishment, and a replenishment element is required. As a result, the replenishment is performed at the timing at which the replenishment can be performed at the same time for the tape feeder 4 at the placement position S2. In addition, the replenishment of the components is required at the time of the batch replenishment for the tape feeder 4 at the placement position S3, but the presetting cannot be performed. As a result, the replenishment cannot be performed for the tape feeder 4 at the placement position S3.

Alternatively, the feeder engaging portion is constituted by the engaging hole (feeder engaging hole 412), while the unit engaging portion is constituted by the engaging protrusion (unit engaging protrusion 572). However, the feeder engaging portion may be constituted by an engaging projection, and the unit engaging portion may be constituted by an engaging hole. Other engagement holes and engagement projections may be appropriately replaced.

The component replenishment carriage 8 may be carried by an unmanned carrier instead of the operator. Alternatively, the robot may be used appropriately in preparation for the collective replenishment of the component replenishment carriage 8.
