Disclosure of Invention

The carrier tape used in the tape feeder is shipped from the manufacturer in a state of being wound around a reel, but an area (terminal remainder) containing no component is provided on the terminal side of the carrier tape. This is mainly due to a technical factor for manufacturing the carrier tape by winding the carrier tape around the reel in a roll form by the manufacturer, but in the automatic loading feeder for automatically loading the carrier tape for replenishment after the preceding carrier tape is discharged, if the terminal remaining portion is long, the time required for the preceding carrier tape to be discharged becomes long, and it takes time until the carrier tape for replenishment is loaded. There is thus currently a need for a carrier tape reel (carrier tape that has been wound in a roll form) that implements a termination process that removes the remainder of the termination to fit into an automatic loading feeder.

Accordingly, an object of the present invention is to provide a carrier tape roll body manufacturing apparatus capable of easily manufacturing a carrier tape roll body subjected to a termination process, a component supply apparatus for supplying a component from a carrier tape roll body, a component mounting system for supplying a component from a carrier tape roll body, and a carrier tape roll body manufacturing method.

The component supply device of the present invention supplies components to a component mounter that mounts components on a substrate, wherein the component supply device supplies components from a carrier tape roll manufactured by the carrier tape roll manufacturing apparatus of the present invention described above.

The component mounting system of the present invention includes at least one component mounter having a component supply device that supplies components from the carrier tape roll body manufactured by the carrier tape roll body manufacturing apparatus of the present invention, and a mounting head that mounts components supplied from the component supply device on a substrate.

The carrier tape roll manufacturing method of the present invention is a method for manufacturing a carrier tape roll using the carrier tape roll manufacturing apparatus of the present invention, wherein the carrier tape roll manufacturing method includes: a pulling-out step of pulling out the carrier tape wound on the original reel to a terminal; a terminal processing step of removing a terminal remainder, which is a region of the terminal side of the carrier tape pulled out by the pulling-out step, that is, a region not containing a component; and rewinding the carrier tape from the new terminal side with respect to the carrier tape subjected to the removal processing of the terminal remainder by the terminal processing step.

According to the present invention, a carrier tape roll body subjected to termination processing can be easily manufactured.

Detailed Description

(embodiment 1)

Fig. 1 shows a component mounting system 1 of embodiment 1 of the present invention. The component mounting system 1 is a system for manufacturing a mounting board KBJ by mounting components BH on a board KB, and includes a solder printer 1A, at least one component mounter 1B, and an inspection machine 1C. The solder printer 1A prints solder on the substrate KB and carries out the solder to the downstream component mounter 1B, and the component mounter 1B mounts a component BH on the substrate KB and carries out the component mounter 1B to the downstream inspection machine 1C (the component mounter 1B in the case where the component mounter 1B is disposed downstream). The inspection machine 1C inspects the component BH mounted on the substrate KB, and carries out the component BH to other devices on the downstream side.

Fig. 2 is a main part side view of the component mounter 1B provided in the component mounting system 1. As shown in fig. 2, the component mounter 1B includes a base 11, a substrate conveying section 12, a feeder carriage 13, a tape feeder 14 as a component supply device, a mounting head 15, and a head moving mechanism 16. The substrate conveying section 12 conveys the substrate KB by a pair of conveyor mechanisms 12a extending in the horizontal direction, and positions the substrate KB at a predetermined working position.

In fig. 2, the feeder carriage 13 is provided with a feeder base 13B at an upper portion, and a plurality of reels RL are supported at a lower portion of the feeder carriage 13. The feeder carriage 13 is coupled to the base 11 by an operator OP performing a traveling operation on the floor surface. A carrier tape CT is wound around each reel RL. A plurality of components BH (details will be described later) are housed in a row in the carrier tape CT.

In fig. 2, the tape feeder 14 is detachably attached to a feeder base 13B of the feeder carriage 13. A plurality of tape feeders 14 can be mounted on the feeder base 13B. A conveyance path 14L for the carrier tape CT is provided inside the tape feeder 14, and a tape insertion port 14G is provided at the end of the rear side (the side of the operator OP in fig. 2).

The tape feeder 14 is an automatic loading feeder, and when the carrier tape CT is inserted from the tape insertion port 14G, a plurality of sprockets (not shown) provided inside are operated to automatically pull in the carrier tape CT and load the carrier tape CT. After the carrier tape CT is loaded, the carrier tape CT is fed at intervals by a sprocket, and the component BH is intermittently supplied to the component supply position 14K.

In fig. 2, the mounting head 15 includes a plurality of nozzles 15N extending downward. Each nozzle 15N can perform a lifting operation with respect to the mounting head 15 and a rotating operation about an up-down axis. The mounting head 15 is capable of vacuum sucking the member BH at the lower end of each nozzle 15N. The head moving mechanism 16 moves the mounting head 15 in the in-plane direction.

When the component mounter 1B mounts components BH onto the substrate KB, first, the substrate conveyance unit 12 is operated to carry in the substrate KB conveyed from the upstream side (the solder printer 1A or the upstream side component mounter 1B) and position the substrate KB at the operation position. The tape feeder 14 is operated and supplies the component BH to the component supply position 14K after positioning the substrate KB, and the mounting head 15 is reciprocated between an upper region of the tape feeder 14 and an upper region of the substrate KB by the head moving mechanism 16.

In this reciprocation, the mounting head 15 repeatedly performs an operation of picking up the component BH supplied from the tape feeder 14 by the nozzle 15N and mounting the component BH at a predetermined position of the substrate KB. Thus, after the component BH to be mounted is mounted on the substrate KB, the substrate conveying section 12 conveys the substrate KB to the downstream side (the component mounter 1B or the inspection machine 1C on the downstream side).

Fig. 3 is a perspective view showing a part of the carrier tape CT used in the component mounter 1B together with the tape feeder 14 and the reel RL. As shown in fig. 3, the carrier tape CT conveyed by the tape feeder 14 on the conveying path 14L naturally comes off the reel RL when reaching the terminal CTs thereof, but in embodiment 1 (and the same applies to embodiments 2 to 4 described later), a region (referred to as "terminal remainder SJ") on the terminal CTs side of the carrier tape CT, which does not include the component BH, is removed, and the tape feeder 14 has a structure without waste for feeding the terminal remainder SJ of the carrier tape CT on the conveying path 14L.

Next, an apparatus and a method for manufacturing a roll (carrier tape roll CTR) of the carrier tape CT with such a terminal residual portion SJ removed will be described.

Fig. 4 and 5 show a carrier tape roll manufacturing apparatus 18 according to embodiment 1 of the present invention. The carrier tape roll manufacturing apparatus 18 is an apparatus that pulls out a carrier tape CT wound around a raw reel 20 to a terminal CTs, performs a terminal process on the carrier tape CT, and then, rolls back the carrier tape CT from the terminal CTs side to manufacture a carrier tape roll CTR. Here, "original reel 20" refers to a reel that is commercially available, i.e., shipped from a component manufacturer. The "termination process" is a process of removing the termination residue SJ of the carrier tape CT.

Before explaining the structure of the carrier tape roll body manufacturing apparatus 18, first, a raw reel 20 will be explained. Fig. 6 is a perspective view of a raw reel 20 used in the carrier tape roll body manufacturing apparatus 18. As shown in fig. 6, the original reel 20 includes a pair of disk-shaped flange portions (referred to as "reel flanges 21") and a cylindrical reel portion 22 sandwiched between the two reel flanges 21. The winding core 22 is provided with a slit 23 having a width slightly larger than the width of the carrier tape CT, and the carrier tape CT is wound around the winding core 22 with the terminal CTs inserted (locked) into the slit 23.

In fig. 6, a rotary shaft insertion hole 24 is provided in the reel core 22 so as to penetrate the center in the axial direction of the original reel 20 (the direction in which the two reel flanges 21 face each other, the front-rear direction, and the X direction). A key groove (original reel key groove 24K) protruding in a direction away from the central axis of the rotation shaft insertion hole 24 is formed in the rotation shaft insertion hole 24.

In fig. 6, the carrier tape CT is configured to have a base tape BT and a cover tape TT.

The rewinding portion 43 is located between the left and right container holding portions 44. In fig. 5 and 8, a vertical tape guide 45 and a component counter 46 are provided at a position on the left side of the base portion 41 in the middle portion in the vertical direction (Z direction) of the base portion 41.

The pull-out unit 42 is a portion of the working unit 32 that pulls out the carrier tape CT from the reel 20 to the terminal CTs. As shown in fig. 5 and 8, the drawer 42 includes a first rotary shaft 51 protruding toward the front side of the base 41, and a first motor 52 provided on the back side of the base 41 and rotating the first rotary shaft 51 (see also fig. 9). The first motor 52 is controlled by the first motor control section 34a of the control device 34.

The rewinding unit 43 is a portion of the working unit 32 from which the carrier tape CT pulled out to the terminal CTS by the pull-out unit 42 is rewound. As shown in fig. 5 and 8, the rewinding part 43 includes a second rotation shaft 53 protruding toward the front side of the base part 41, and a second motor 54 provided on the back side of the base part 41 and rotating the second rotation shaft 53. The second motor 54 is controlled by the second motor control section 34b of the control device 34.

In fig. 8, a drawer winding core 61 is detachably attached to the first rotary shaft 51 of the drawer 42. The pull-out portion core 61 constitutes a pull-out portion core unit 64 (fig. 8, 9, 10A, and 10B) together with a pair of flange portions 62 and a width adjustment member 63. Fig. 10A and 10B are a rear view and a side view of the drawer core unit 64, respectively.

In fig. 8, 9, 10A, and 10B, the two flange portions 62 each have a disk-like shape, and the two flange portions 62 are provided so as to sandwich the pull-out portion winding core 61 from the deep side and the near side. The width adjusting member 63 is formed as a whole of a cylindrical member, and is inserted into the drawer winding core 61. The width adjustment member 63 is located on the near side of the flange portion 62 on the near side of the two flange portions 62, and is provided integrally with the flange portion 62 on the near side.

In fig. 9, 10A, and 10B, a first rotation shaft insertion hole 65 through which the first rotation shaft 51 is inserted is formed in the pullout portion winding core 61. Fig. 11 is a side view of the pull-out portion 42. When the drawer core 61 is attached to the first rotary shaft 51, the first rotary shaft 51 is inserted into the first rotary shaft insertion hole 65 (fig. 9 to 11) provided in the drawer core 61.

The front end 51S of the first rotary shaft 51 inserted through the first rotary shaft insertion hole 65 protrudes from the end of the pull-out unit winding core 61 on the near side (fig. 11), and a stopper member 66 is screwed into the protruding front end 51S of the first rotary shaft 51. The stopper member 66 serves to prevent the width adjustment member 63 from coming out of the pull-out portion core 61.

In fig. 9, 10A, and 10B, a key groove (pull-out key groove 67) connected to the first rotation shaft insertion hole 65 is formed in the flange portion 62 on the deep side (base portion 41 side) of the pull-out portion winding core 61. Fig. 12 is a perspective view of the first rotation shaft 51 provided in the drawer 42. As shown in fig. 9 and 12, a key portion (first rotation shaft key portion 51K) is provided at the root portion of the first rotation shaft 51 so as to protrude outward from the outer peripheral surface of the first rotation shaft 51.

When the first rotation shaft 51 is inserted into the first rotation shaft insertion hole 65 of the pull-out unit core 61, the first rotation shaft key portion 51K is fitted into the pull-out unit key groove 67. Thereby, the relative rotation of the pull-out unit winding core 61 with respect to the first rotation shaft 51 is restricted, and when the first rotation shaft 51 is rotated, the pull-out unit winding core 61 rotates integrally with the first rotation shaft 51.

In fig. 9, 10B, and 11, a slit-shaped carrier tape insertion port 61S extending in the axial direction is provided in the pullout portion winding core 61. A leading end CTT (fig. 6) of the carrier tape CT to be pulled out from the original reel 20 is inserted into the carrier tape insertion port 61S.

In fig. 9, 10B, and 11, a grip lever 70 is provided at an axial end of the pull-out unit core 61. A gripping mechanism (not shown) including two members capable of performing an opening and closing operation (gripping operation) by an operation of the gripping operation lever 70 is provided inside the drawer core 61.

The operator OP can clamp the leading end CTT of the carrier tape CT inserted from the carrier tape insertion port 61S by the clamping operation of the clamping mechanism by the clamping lever 70. When the first rotation shaft 51 is driven to rotate the drawer core 61 in a state where the leading end CTT of the carrier tape CT is held by the holding mechanism, the carrier tape CT is wound around the outer periphery of the drawer core 61.

In fig. 11, 13A, and 13B, a lock knob 63L that is manually operated is provided to the width adjustment member 63. The operator OP slides the width adjustment member 63 relative to the drawer core 61 in the axial direction (X direction) of the drawer core 61, and engages an engagement piece (not shown) provided in the lock knob 63L with one of the plurality of recesses 68H of the locked portion 68 at a desired position, whereby the width adjustment member 63 can be locked relative to the drawer core 61. Thus, the width of the pull-out unit winding core 61 (the distance WD. between the two flange portions 62, fig. 11) can be adjusted in accordance with the size of the width of the carrier tape CT to be wound around the pull-out unit winding core 61 (fig. 13A and 13B).

In fig. 11, 13A, and 13B, a display portion 69 is provided on the surface of the pullout portion core 61. A plurality of characters (e.g., numerals) NB corresponding to the plurality of recesses 68H of the locked portion 68 (i.e., corresponding to the width dimension of the carrier tape CT) are displayed on the display portion 69, and the operator OP can lock the width adjustment member 63 at an appropriate position in the width dimension (distance WD between the two flange portions 62) by determining the position of the width adjustment member 63 with respect to the drawer winding core 61 using the characters NB displayed on the window portion 63W of the width adjustment member 63 as a reference.

Fig. 14 is a perspective view of the working unit 32 provided in the carrier tape roll body manufacturing apparatus 18. Fig. 15 and 16 are a partially exploded side view and a side view, respectively, of the rewinding section 43 provided in the carrier tape roll manufacturing device 18. In fig. 14, the original reel 20 is first assembled to the second rotation shaft 53 of the rewinding unit 43 (at the time of pulling out the carrier tape CT by the pulling-out unit 42). As shown in fig. 14, 15, and 16, a key portion (second rotation shaft key portion 53K) is provided at the root portion of the second rotation shaft 53 so as to protrude outward of the outer peripheral surface of the second rotation shaft 53.

When the second rotation shaft 53 is inserted into the primary reel 20, the secondary rotation shaft key 53K is fitted into the primary reel key groove 24K (fig. 15 to 16). Thereby, the relative rotation of the original reel 20 with respect to the second rotation shaft 53 is restricted, and when the second rotation shaft 53 is rotated, the original reel 20 rotates integrally with the second rotation shaft 53.

After the original reel 20 is mounted on the second rotation shaft 53 of the rewinding unit 43, the operator OP pulls the leading end CTT of the carrier tape CT upward from the original reel 20. Then, the gripping lever 70 is operated, and the leading end CTT of the carrier tape CT is inserted into the carrier tape insertion port 61S of the pull-out unit core 61, thereby gripping the gripping mechanism. As a result, the carrier tape CT wound around the original reel 20 is connected to the pull-out unit core 61 (fig. 17). Fig. 17 is a perspective view of the working unit 32.

Here, as described above, the width of the pull-out unit winding core 61 can be adjusted in accordance with the width of the carrier tape CT by changing the distance WD between the two flange portions 62 of the pull-out unit winding core 61. Therefore, it is not necessary to replace the pull-out portion winding core 61 itself with respect to the first rotation shaft 51 according to the width of the carrier tape CT to be pulled out.

After the carrier tape CT wound around the original reel 20 is connected to the pullout portion core 61 as described above, the operator OP operates the pullout switch 33a from the operation portion 33 (fig. 7). When the pullout switch 33a is operated, the first motor control unit 34a operates the first motor 52 to rotate the first rotary shaft 51, and the second motor control unit 34b operates the second motor 54 to rotate the second rotary shaft 53 in the same direction as the first rotary shaft 51.

Therefore, the pullout portion core 61 rotates in the same direction as the original reel 20, and the carrier tape CT wound around the original reel 20 is wound around the pullout portion core 61 (fig. 18A to fig. 18B to fig. 18C). Fig. 18A to 18C are diagrams showing a case where the carrier tape CT is pulled out from the original reel 20 by the pulling-out portion 42. Then, the carrier tape CT is pulled out to the terminal CTs by the pulling-out section 42 (pulling-out step). In this way, the first motor 52 of the pullout portion 42 drives the pullout portion core 61 in the pullout step, and the carrier tape CT is wound around the pullout portion core 61 from the original reel 20.

The carrier tape CT moving between the rewinding portion 43 (the original reel 20) and the pulling-out portion 42 (the pulling-out portion core 61) is arranged to pass through a predetermined detection position. Here, the detection position is set to a position between the two tape guides 45 and the component counter 46, which are arranged in the up-down direction on the base portion 41.

The component counter 46 detects the component BH passing the detection position and counts the number thereof. The position calculating unit 34c of the control device 34 calculates the positions of the start CTT and the end CTs of the carrier tape CT (the length from the detection position to the start CTT of the carrier tape CT and the length from the detection position to the end CTs of the carrier tape CT) based on the number of parts BH counted by the part counter 46 and other information stored in advance in the control device 34.

As described above, in the present embodiment, the component counter 46 and the position calculating unit 34c of the control device 34 serve as the tape end position detecting unit TK (fig. 7) that detects the position of the end (the terminal CTs or the start CTT) of the carrier tape CT that moves between the pull-out unit 42 and the rewinding unit 43.

The first motor control unit 34a controls the operations of the first motor 52 and the second motor based on the position of the terminal CTs of the carrier tape CT calculated by the tape end position detection unit TK. The determination unit 34d of the control device 34 determines whether or not the pull-out unit winding core 61 reaches the stop position at which the winding of the carrier tape CT should be stopped, based on the position of the terminal CTs of the carrier tape CT detected by the tape end position detection unit TK.

When it is detected that the carrier tape CT wound around the original reel 20 is pulled out by the pull-out unit 42 and the pull-out unit core 61 approaches the stop position, the first motor control unit 34a decelerates the rotation of the first motor 52. Then, when the carrier tape CT is further pulled out by the pulling-out portion 42 (fig. 18C) and it is determined by the determination portion 34d that the pulling-out portion core 61 reaches the stop position, the first motor control portion 34a stops the rotation of the first rotation shaft 51 (that is, the rotation of the pulling-out portion core 61) (fig. 19). Fig. 19 is a perspective view of the working unit 32.

In this way, the carrier tape roll manufacturing apparatus 18 includes the determination unit 34d that determines whether or not the pull-out unit core 61 has reached the stop position at which the winding of the carrier tape CT is stopped based on the position of the terminal CTs of the carrier tape CT detected by the tape end position detection unit TK, and the first motor control unit 34a stops the operation of the first motor 52 when it is determined by the determination unit 34d that the pull-out unit core 61 has reached the stop position. When the approaching of the pull-out unit core 61 to the stop position is detected based on the position of the terminal CTs of the carrier tape CT detected by the tape end position detecting unit TK, the first motor control unit 34a decelerates the rotation of the first motor 52.

In this way, when the carrier tape CT is wound by the pullout portion core 61 by the pullout portion 42, the first motor control portion 34a controls the rotation of the first motor 52 by the speed control, and the second motor control portion 34b controls the second motor 54 by the torque control for generating the torque in the direction opposite to the winding direction based on the first motor 52 and maintaining the tension of the carrier tape CT.

Fig. 20A and 20B are explanatory views of the terminal end and the remaining part of the carrier tape CT pulled out by the pulling-out section 42. After the pull-out unit 42 pulls out the carrier tape CT from the reel 20 to the terminal CTs, the operator OP performs terminal processing (terminal processing step) of the carrier tape CT. Here, the term "termination processing" means processing for removing the termination residue SJ of the carrier tape CT (the region of the carrier tape CT on the side of the termination CTs that does not include the member BH) as described above, and the cutting processing is performed by cutting the termination residue from the carrier tape CT by a cutting mechanism (e.g., scissors) (fig. 20A to 20B).

Fig. 21 is a view showing a state in which the terminal end of the carrier tape CT pulled out by the pulling-out section 42 is attached to the reel body 81. Fig. 22 is a front view of the working unit 32. Fig. 23 is a diagram showing a state in which the terminal end of the carrier tape CT pulled out by the pulling-out section 42 is attached to the reel body 81. After the end processing of the carrier tape CT pulled out by the pulling-out unit 42, the operator OP removes the empty raw reel 20 from the second rotation shaft 53, and mounts the wound body 80 on the second rotation shaft 53. The roll 80 is a member detachably attached to the second rotation shaft 53 as a roll holding portion for rewinding the carrier tape CT pulled out from the reel 20 by the pull-out portion 42.

As the roll 80, for example, an empty reel RL that supplies the carrier tape CT to the tape feeder 14 and runs out of components, and a raw reel 20 that is pulled out by the pull-out portion 42 and becomes empty (collectively referred to as a reel body 81, fig. 21) are used. As described in the explanation of the original reel 20, the reel body 81 includes the reel flange 21 and the reel core 22, and the reel core 22 includes the slit 23 and the rotation shaft insertion hole 24.

When the reel body 81 is used as the winding body 80, the reel body 81 is mounted on the second rotation shaft 53 (fig. 22). The procedure for assembling the reel body 81 to the second rotary shaft 53 is the same as that for assembling the original reel 20 to the second rotary shaft 53. When the empty reel of the original reel 20 is used as the reel body 81, the empty reel may be used as it is without being removed from the second rotary shaft 53.

After the reel body 81 is assembled to the second rotation shaft 53, the terminal CTs of the carrier tape CT in the pulled-out state of the pull-out portion 42 is then connected to the reel core 22 of the reel body 81 by the adhesive tape NT (fig. 21 and 23). The adhesive force of the adhesive tape NT used here is a relatively weak adhesive force that the terminal end CTs of the carrier tape CT does not slip with respect to the winding core 22 when the winding reel body 81 starts winding the carrier tape CT, and that the terminal end CTs of the carrier tape CT can be separated from the winding core 22 without resistance when the carrier tape CT is pulled out to the terminal end CTs.

After the terminal CTs of the carrier tape CT is connected to the winding core 22 of the winding body 81 by the adhesive tape NT as described above, the operator OP operates the rewind switch 33b (fig. 7) from the operation unit 33. When the rewind switch 33b is operated, the second motor control unit 34b operates the second motor 54 to rotate the second rotary shaft 53, and the first motor control unit 34a operates the first motor 52 to rotate the first rotary shaft 51 in the same direction as the second rotary shaft 53.

Therefore, the reel body 81 and the drawer core 61 rotate in the same direction, and the carrier tape CT wound around the drawer core 61 is wound around the core 22 of the reel body 81 (fig. 24A to 24B to 24C). Fig. 24A to 24C are diagrams showing a case where the carrier tape CT is rewound from the pull-out portion 42 by the rewinding portion 43. The carrier tape CT is thus rewound onto the reel body 81, which is the winding body 80 (rewinding step). In this way, the second motor 54 of the rewinding unit 43 rolls the carrier tape CT wound around the pullout portion core 61 of the pullout portion 42 in the rewinding step.

When the carrier tape CT is rewound onto the reel body 81, the tape end position detecting section TK detects the leading end CTT of the carrier tape CT. The second motor control unit 34b decelerates the rotation of the second motor 54 when the tape end position detection unit TK detects that the reel body 81 is close to the winding stop position, which is the position at which the rewinding operation of the carrier tape CT should be stopped, and then stops the rotation of the second motor 54 when the reel body 81 is detected to reach the winding stop position.

In this way, when the rewinding unit 43 winds the carrier tape CT by the winding body 80 (here, the reel body 81), the second motor control unit 34b controls the rotation of the second motor 54 by the speed control, and the first motor control unit 34a controls the first motor 52 by the torque control for generating the torque in the direction opposite to the winding direction by the second motor 54 and maintaining the tension of the carrier tape CT.

After the carrier tape CT is rewound onto the reel body 81 and the rotation of the second rotation shaft 53 and the first rotation shaft 51 is stopped (fig. 24C), the leading end CTT of the carrier tape CT held by the pull-out unit core 61 is removed from the pull-out unit core 61. After the carrier tape CT is taken out from the pullout portion core 61, the carrier tape roll CTR is manufactured in the reel body 81 on the second rotation shaft 53. After the carrier tape roll CTR is thus manufactured, the operator OP removes the reel body 81 together with the carrier tape roll CTR from the second rotation shaft 53 (fig. 25). Fig. 25 is a perspective view of the working unit 32.

The carrier tape roll manufacturing apparatus 18 includes: a pull-out unit 42 that pulls out the carrier tape CT from the raw reel 20 around which the carrier tape CT is wound to the terminal CTs; and a rewinding section 43 for rewinding the carrier tape CT pulled out by the pull-out section 42 from the terminal CTs side. The carrier tape roll CTR is manufactured by a method (carrier tape roll manufacturing method) including a pulling-out step of pulling out the carrier tape CT from the original reel 20 to the terminal CTs by the pulling-out section 42, a terminal processing step of removing the terminal surplus portion SJ, which is a region on the terminal side of the carrier tape CT pulled out in the pulling-out step and which is a region where no component is included, and a rewinding step of rewinding the carrier tape CT, which has been removed from the terminal surplus portion SJ in the terminal processing step, from the new terminal CTs side by the rewinding section 43. Therefore, the carrier tape roll CTR subjected to the termination process can be easily manufactured.

(embodiment 2)

Next, embodiment 2 is shown. Fig. 26 is a perspective view of a working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 2 of the present invention. Fig. 27A and 27B are perspective views of a replacement winding core 82 included in the carrier tape roll manufacturing apparatus according to embodiment 2 of the present invention. Fig. 28A to 29B are operation explanatory views of the replacement winding core 82. The carrier tape roll manufacturing apparatus of embodiment 2 is similar in structure to that of embodiment 1, except that a replacement core 82 shown in fig. 26 is used as a roll 80. As shown in fig. 27A, 27B, 28A, and 28B, the replacement core 82 includes a base 91, left and right semicircular cylindrical portions 92, a lever 93, and a clamp 94.

In fig. 27A, 27B, 28A, and 28B, an insertion hole 95 into which the second rotation shaft 53 is inserted is provided in the base 91 of the replacement core 82. The insertion hole 95 is formed with a key groove 95M protruding in a direction away from a central axis of the insertion hole 95.

In fig. 27A, 27B, 28A, and 28B, left and right semi-cylindrical portions 92 are arranged on the left and right sides of the base 91. The left and right semicircular cylindrical portions 92 are coupled to the base 91 by left and right swing shafts 96 extending in the Y direction. Therefore, the two semicircular cylinder portions 92 are swingable about the swing shaft 96, and are movable (swingable) between a reference position (fig. 27A, 27B, and 28A) in which the outer peripheral surface is located on the common cylindrical surface and a deformed position (fig. 28B) in which the outer peripheral surface is not located on the common cylindrical surface (narrowed downward). In the deformed position, the lower portions of the two half cylindrical portions 92 move in the approaching direction to each other, and have a downward narrowed shape.

In fig. 28A and 28B, a biasing spring 97 is provided between the lower portion of each of the left and right semi-cylindrical portions 92 and the base 91. The left and right semicircular cylindrical portions 92 are biased in a direction in which the lower portions approach each other (i.e., in a direction that becomes a deformed position) by the left and right biasing springs 97.

In fig. 27A, 28A, and 28B, the lever 93 is constituted by a member having a shape extending in one direction. The lever 93 is coupled at its center to the lower portion of the base 91 by a shaft member 98 extending in the Y direction. The lever 93 is rotatable about the shaft member 98.

In fig. 28A and 28B, an elliptical cam 99 is attached to the lever 93, and rotates integrally with the lever 93 about the shaft member 98. The cam 99 is movable between a winding-time posture (fig. 28A) extending in the horizontal direction and a drawing-time posture (fig. 28B) extending in the vertical direction according to the rotational position of the lever 93 relative to the base 91.

When the cam 99 is in the winding posture, both end portions on the long side of the cam 99 enter between the lower portions of the left and right semi-cylindrical portions 92 and come into contact with each other from the inner surface sides of the left and right semi-cylindrical portions 92. Therefore, the left and right semi-cylindrical portions 92 are expanded between the lower portions against the urging force of the left and right urging springs 97 to become reference positions (fig. 28A).

On the other hand, when the cam 99 is in the withdrawal-time posture, both end portions on the long side of the cam 99 do not come into contact with the inner surfaces of the left and right semi-cylindrical portions 92. Therefore, the left and right semi-cylindrical portions 92 are pulled toward each other by the urging force of the left and right urging springs 92 to be positioned at the deformed position (fig. 28B).

In fig. 28A and 28B, the clamp portion 94 includes a clamp base 94a attached to the lower end of the base 91 and extending upward, a clamp piece 94B attached to the upper end of the clamp base 94a, and a torsion spring 94c interposed between the clamp base 94a and the base 91. The torsion spring 94c is provided to urge the clamp base 94a in a direction in which the clamp piece 94b is abutted against the abutted surface 92P on one upper portion of the left and right semi-cylindrical portions 92.

The holding piece 94B that is brought into contact with the abutted surface 92P is separated from the abutted surface 92P against the urging force of the torsion spring 94c, and the carrier tape CT is inserted between the holding piece 94B and the abutted surface 92P and then released, whereby the carrier tape CT can be sandwiched (held) between the holding piece 94B and the abutted surface 92P (fig. 29A to 29B). This allows the terminal CTs of the carrier tape CT pulled out from the original reel 20 by the pull-out unit 42 to be connected to the replacement core 82. The replacement core 82 may hold a plurality of kinds of carrier tapes CT having different width dimensions, but a plurality of kinds of replacement cores 82 having the most suitable axial length may be prepared in advance according to the width dimensions of the carrier tapes CT.

Fig. 30 is a perspective view of a working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 2 of the present invention. When the replacement core 82 is used for the wound body 80, first, the replacement core 82 is attached so that the second rotation shaft 53 of the rewinding part 43 is inserted into the insertion hole 95 provided in the base 91 (fig. 30). When the second rotation shaft 53 is inserted into the insertion hole 95, the second rotation shaft key 53K is fitted into the key groove 95M of the replacement winding core 82. After the replacement core 82 is assembled to the second rotating shaft 53, the terminal CTs of the carrier tape CT pulled out by the pull-out portion 42 is held between the holding portion 94 and the abutted surface 92P, whereby the carrier tape CT is connected to the replacement core 82 (i.e., the rewind portion 43) (fig. 30).

Fig. 31A to 31C are diagrams showing a case where the carrier tape CT is rewound from the pull-out unit 42 by the rewinding unit 43 of the carrier tape roll manufacturing device according to embodiment 2 of the present invention. After connecting the terminal CTs of the carrier tape CT to the replacement winding core 82, the operator OP operates the rewind switch 33b from the operating unit 33. When the rewind switch 33b is operated, the second motor control unit 34b operates the second motor 54 to rotate the second rotary shaft 53. The first motor control unit 34a operates the first motor 52 to rotate the first rotary shaft 51 in the same direction as the second rotary shaft 53. As a result, the replacement core 82 and the drawer core 61 rotate in the same direction, and the carrier tape CT wound around the drawer core 61 is pulled out toward the rewind portion 43 side and wound around the replacement core 82 (specifically, the outer peripheral surfaces of the two semicircular cylindrical portions 92) (fig. 31A to 31B to 31C, the rewind step).

When the carrier tape CT is wound around the replacement core 82 (rewound to the rewinding unit 43), the position of the leading end CTT of the carrier tape CT is detected by the tape end position detecting unit TK, as in the case of embodiment 1. When the determination unit 34d detects that the winding stop position of the replacement core 82 is reached, the second motor control unit 34b starts decelerating the second motor 54, and then, when the determination unit 34d detects that the winding stop position of the replacement core 82 is reached, the second motor 54 is stopped.

In the process of stopping the second motor 54, the second motor 54 is decelerated and stopped based on the position of the leading end CTT of the carrier tape CT detected by the tape end position detecting unit TK, as in the case of embodiment 1. In addition, when rewinding the carrier tape CT to the winding body 80 (here, the replacement core 82), the second motor control unit 34b controls the rotation of the second motor 54 by speed control, and the first motor control unit 34a performs the rotation of the first motor 52 by torque control, as in the case of embodiment 1.

After the carrier tape CT is rewound to the replacement core 82 and the rotation of the second rotation shaft 53 and the first rotation shaft 51 is stopped (fig. 31C), the leading end CTT of the carrier tape CT held by the pullout core 61 is removed from the pullout core 61. After the carrier tape CT is removed from the pullout portion core 61, the carrier tape roll CTR is manufactured on the replacement core 82. After the carrier tape roll CTR is thus manufactured, the operator OP removes the replacement core 82 from the second rotation shaft 53 for each carrier tape roll CTR (fig. 32). Fig. 32 is a perspective view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 2.

The operator OP removes the replacement core 82 from the second rotation shaft 53 for each carrier tape roll CTR, and then pulls out the replacement core 82 from the carrier tape roll CTR. In this case, the operator OP rotates the rod 93 of the replacement core 82 about the shaft member 98, and sets the winding posture to the extraction posture (fig. 28A to 28B). As a result, the left and right semicircular cylindrical portions 92 of the replacement core 82 swing in the direction in which the lower portions approach each other, and are deformed so as to be narrowed downward (fig. 28B), so that the replacement core 82 can be easily pulled out from the carrier tape roll CTR (fig. 32). In this way, in the carrier tape roll manufacturing apparatus 18, the replacement roll core 82 is deformed so as to be able to be pulled out from the center portion (circular hole portion) of the carrier tape roll CTR constituted by the rewound carrier tape CT.

In embodiment 2, the end process of removing the end surplus portion SJ of the carrier tape CT pulled out by the pull-out portion 42 can be performed and the rewinding is performed by the rewinding portion 43, so that the carrier tape carrier CTR subjected to the end process can be easily manufactured.

Embodiment 3

Next, embodiment 3 is shown. Fig. 33 is a perspective view of a working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 3 of the present invention. Fig. 34A and 34B are explanatory views of a storage container 83 provided in the carrier tape roll body manufacturing apparatus according to embodiment 3 of the present invention. In embodiment 3, the replacement winding core 82 shown in embodiment 2 is used as the winding body 80, and the storage container 83 shown in fig. 33 is used at the same time.

As shown in fig. 33, 34A, and 34B, the storage container 83 includes two side plates 101 and a circular arc-shaped frame 102 located between the two side plates 101, and has an opening 103 at the upper side. An arc-shaped shutter 104 that moves along the inner surface of the frame 102 is provided inside the storage container 83.

The shutter 104 can be located at either one of an open position (fig. 34A) where the opening 103 is opened and a closed position (fig. 34B) where the opening 103 is closed. The gate 104 is provided with an operation lever 104L, and the operator OP switches the position of the gate 104 by operating the operation lever 104L.

In fig. 33, 34A, and 34B, core holes 105 into which the replacement cores 82 can be inserted are provided in both side plates 101. The inner diameter of the core hole 105 is slightly larger than the outer diameter of the replacement core 82 (the outer diameter of the replacement core 82 when the two half cylindrical portions 92 are positioned at the reference position).

In embodiment 3, first, the storage container 83 is attached to the base portion 41. When the storage container 83 is attached to the base portion 41, the storage container 83 having the opening 103 oriented upward is held by the left and right storage container holding portions 44 provided at the lower portion of the base portion 41. At this time, the second rotation shaft 53 penetrates the core holes 105 of the two side plates 101. In a state where the storage container 83 is attached to the base portion 41, the second rotation shaft 53 is positioned on a line connecting the centers of the two core holes 105.

After the storage container 83 is attached to the base portion 41 as described above, the operator OP attaches the replacement winding core 82 to the second rotation shaft 53. When the second rotation shaft 53 is inserted into the insertion hole 95 (fig. 27A and 27B) of the replacement core 82, the replacement core 82 is directly fitted to the second rotation shaft 53 by inserting the two core holes 105 provided in the two side plates 101 of the storage container 83 (fig. 35). Fig. 35 is a front view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 3 of the present invention.

Fig. 36A to 36C are diagrams showing a case where the carrier tape CT is rewound from the pull-out unit 42 by the rewinding unit 43 of the carrier tape roll manufacturing device according to embodiment 3 of the present invention. After the replacement core 82 is mounted on the second rotation shaft 53, the terminal CTs of the carrier tape CT in the pulled-out state of the pull-out unit 42 is connected to the replacement core 82 in the same manner as in the case of embodiment 2 (fig. 35). The rewind switch 33b is operated by the operation unit 33. When the rewind switch 33B is operated, the first rotary shaft 51 is rotated in the same direction as the second rotary shaft 53, and the carrier tape CT wound around the pullout portion winding core 61 is wound around the outer peripheral surfaces of the two semicircular cylindrical portions 92 of the replacement winding core 82 (fig. 36A to 36B to 36C), as in the case of embodiment 2 (rewind step).

When the carrier tape CT is rewound onto the replacement winding core 82, the position of the leading end CTT of the carrier tape CT is detected by the tape end position detecting unit TK. The same applies to embodiment 2, in which the second motor control unit 34b starts deceleration of the second motor 54 when the determination unit 34d detects that the winding stop position of the replacement core 82 is reached, and then stops the second motor 54 when the determination unit detects that the winding stop position of the replacement core 82 is reached.

In the process of stopping the second motor 54, the second motor 54 is decelerated and stopped based on the position of the leading end CTT of the carrier tape CT detected by the tape end position detecting unit TK, similarly to the cases of embodiments 1 and 2. When rewinding the carrier tape CT onto the wound body 80 (the replacement core 82), the second motor control unit 34b controls the rotation of the second motor 54 by speed control, and the first motor control unit 34a controls the rotation of the first motor 52 by torque control, as in the case of embodiments 1 and 2.

After the carrier tape CT is rewound to the replacement core 82 and the rotation of the second rotation shaft 53 and the first rotation shaft 51 is stopped (fig. 36C), the leading end CTT of the carrier tape CT held by the pullout core 61 is removed from the pullout core 61. After the carrier tape CT is removed from the drawer core 61, the carrier tape roll CTR is manufactured on the replacement core 82 in the storage container 83.

Fig. 37A and 37B are diagrams showing a procedure of sealing the carrier tape carrier CTR in the storage container 83. After the carrier tape roll CTR is manufactured in this manner, the operator OP stores the leading end CTT of the carrier tape CT in the storage container 83. Then, the shutter 104 is set from the open position to the closed position (fig. 37A to 37B) by operating the operation lever 104L, and the carrier tape roll CTR is sealed in the storage container 83.

Fig. 38 is a perspective view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 3 of the present invention. After sealing the carrier tape roll CTR in the storage container 83, the operator OP removes the replacement core 82 from the second rotation shaft 53 for each carrier tape roll CTR (i.e., for each storage container 83), and then pulls out the replacement core 82 from the carrier tape roll CTR (fig. 38). Thereby, the carrier tape roll CTR stored in the storage container 83 is obtained.

In embodiment 3, the end process of removing the end surplus portion SJ of the carrier tape CT pulled out by the pull-out portion 42 can be performed and the rewinding is performed by the rewinding portion 43, so that the carrier tape carrier CTR subjected to the end process can be easily manufactured.

As a modification of embodiment 3, as shown in fig. 39A and 39B, the second rotation shaft 53 (and hence the replacement winding core 82) may be disposed above the storage container 83 without being disposed in the storage container 83 attached to the base portion 41. Fig. 39A and 39B are perspective views of the working unit 32 of the carrier tape roll body manufacturing apparatus according to a modification of embodiment 3 of the present invention. In this configuration, the carrier tape roll CTR wound around the replacement core 82 is stored in the storage container 83 by its own weight when the replacement core 82 is pulled out from the second rotation shaft 53 (fig. 39A to 39B).

In the above-described configuration, as shown in fig. 39A and 39B, it is preferable that the working unit 32 (i.e., the base unit 41) including the pull-out unit 42 and the rewind unit 43 is inclined from the vertical plane, that is, the elevation angle θ with respect to the horizontal plane is slightly smaller than 90 degrees (for example, θ=60°). In this configuration, the carrier tape carrier CTR slides on the surface of the base portion 41 and is stored in the storage container 83, so that the impact of the carrier tape CT from the storage container 83 side can be relaxed when the carrier tape carrier CTR contacts the storage container 83.

Embodiment 4

Next, embodiment 4 is shown. Fig. 40 is a perspective view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 4 of the present invention. Fig. 41 is an exploded view of a split reel 84 provided in a carrier tape roll body manufacturing apparatus according to embodiment 4 of the present invention. The carrier tape roll manufacturing apparatus of embodiment 4 is similar in configuration to those of embodiments 1 to 3 except that a split reel 84 shown in fig. 40 and 41 is used as a roll 80.

In fig. 41, the split reel 84 has two flange bodies 111 and a carrier tape spool 112 disposed between the two flange bodies 111. The carrier tape core 112 is coupled to one flange 111.

In fig. 41, the two flange bodies 111 are coupled by fitting a plurality of concave portions 113 provided in the carrier tape core 112 of one flange body 111 with a plurality of convex portions 114 provided in the other flange body 111. Therefore, the split reel 84 can be easily split into two parts (one flange body 111 and the other flange body 111). The split reel 84 is configured to be split into two parts here, but may be configured to be split into two or more parts.

Fig. 42 is a perspective view of the split reel 84. In fig. 42, the carrier tape core 112 is provided with a rotary shaft insertion hole 115 penetrating a central portion in a width direction (a direction in which the two flange bodies 111 face each other). A key groove (split-spool key groove 115K) protruding radially outward of the rotary shaft insertion hole 24 is formed in the insertion hole 115.

When the split reel 84 is used as the wound body 80, first, the second rotation shaft 53 is inserted into the insertion hole 115 (fig. 40) of the split reel 84. At this time, the second rotation shaft key 53K is fitted into the split reel key groove 115K. Thereby, the relative rotation of the drawer core 61 with respect to the first rotation shaft 51 is restricted, and when the second rotation shaft 53 is rotated, the split reels 84 rotate integrally with the second rotation shaft 53.

Fig. 43 is a diagram showing a state in which the end of the carrier tape CT pulled out by the pulling-out unit 42 provided in the carrier tape roll body manufacturing apparatus according to embodiment 4 of the present invention is connected to the carrier tape roll core 112 of the split reel 84. Fig. 44 is a front view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 4 of the present invention. After the split reel 84 is mounted on the second rotary shaft 53, the terminal end CTs of the carrier tape CT in the state pulled out by the pull-out portion 42 is then connected to the carrier tape core 112 of the split reel 84 by the adhesive tape NT in the same manner as in the case of embodiment 1 (fig. 43 and 44). After the terminal CTs of the carrier tape CT is connected to the carrier tape reel 112 of the split reel 84 by the adhesive tape NT, the operator OP operates the rewind switch 33b from the operating unit 33. Accordingly, the second rotating shaft 53 rotates in the same direction as the first rotating shaft 51, and the carrier tape CT wound around the pullout portion winding core 61 is rewound onto the split reel 84 (fig. 45A to 45B to 45C, the rewinding step). Fig. 45A to 45C are diagrams showing a case where the carrier tape CT is rewound from the pull-out unit 42 by the rewinding unit 43 of the carrier tape roll manufacturing device according to embodiment 4 of the present invention.

At this time, the tape end position detecting unit TK detects the position of the leading end CTT of the carrier tape CT, and the second motor control unit 34b decelerates and stops the second motor 54, as in the case of embodiments 1, 2, and 3. When the carrier tape CT is wound around the wound body (here, the split reel 84), the second motor control unit 34b controls the rotation of the second motor 54 by speed control, and the first motor control unit 34a controls the rotation of the first motor 52 by torque control, as in the cases of embodiments 1, 2, and 3.

After the carrier tape CT is rewound onto the split reel 84 and the rotation of the second rotation shaft 53 and the first rotation shaft 51 is stopped, the leading end CTT of the carrier tape CT held by the pull-out unit core 61 is removed from the pull-out unit core 61. After the carrier tape CT is taken out from the pullout unit core 61, the carrier tape carrier CTR is manufactured on the split reel 84. After the carrier tape roll CTR is thus manufactured, the operator OP removes the split reel 84 from the second rotation shaft 53 for each carrier tape roll CTR (fig. 46). Fig. 46 is a perspective view of the working unit 32 included in the carrier tape roll body manufacturing apparatus according to embodiment 4 of the present invention.

This results in the carrier tape roll CTR stored in the split reel 84. The operator OP may pull the two flange bodies 111 apart as needed to divide the split reels 84, and use the carrier tape carrier CTR as a single body.

In embodiment 4, the end process of removing the end surplus portion SJ of the carrier tape CT pulled out by the pull-out portion 42 can be performed and the rewinding is performed by the rewinding portion 43, so that the carrier tape carrier CTR subjected to the end process can be easily manufactured.

As described above, the carrier tape roll manufacturing apparatus 18 according to embodiments 1 to 4 includes the pull-out unit 42 that pulls out the carrier tape CT from the original reel 20 to the terminal CTs, and the rewind unit 43 that rewound the carrier tape CT pulled out by the pull-out unit 42 from the terminal CTs side, and after the terminal surplus portion SJ (the area on the terminal CTs side that does not include the member BH) of the carrier tape CT pulled out by the pull-out unit 42 is removed, the carrier tape CT is rewound from the new terminal CTs side. Therefore, according to the carrier tape roll body manufacturing apparatus 18 of embodiments 1 to 4, the carrier tape roll body CTR subjected to the termination process can be easily manufactured.

The embodiments of the present invention have been described above, but the present invention is not limited to the above, and various modifications and the like can be made. For example, the drawing unit 42 may be configured to draw the carrier tape CT from the original reel 20 around which the carrier tape CT is wound to the terminal CTs, and is not limited to the configurations shown in embodiments 1 to 4. The rewinding unit 43 may be configured to rewind the carrier tape CT pulled out by the pulling-out unit 42 from the terminal CTs side to generate a carrier tape roll CTR, which is a roll of the carrier tape CT, and is not limited to the configurations shown in embodiments 1 to 4.

In embodiments 1 to 4, the reel 20 from which the carrier tape CT is pulled out by the pull-out section 42 is held by the second rotating shaft 53 which is a part of the carrier tape roll body manufacturing apparatus 18, and the second rotating shaft 53 which is a winding body holding section is also a holding section for the reel 20, but instead of this, a reel holding section for holding the reel 20 may be provided separately, and the carrier tape CT may be pulled out from the reel 20 held by the pull-out section 42.

In embodiments 1 to 4, the plurality of working units 32 including the pull-out unit 42 and the rewinding unit 43 are provided, but this is an example, and the working units 32 may be one or three or more. When the number of work units 32 is two or more, the plurality of carrier tape reels CTR can be simultaneously manufactured in parallel, but it is preferable to set the optimum number in consideration of the work efficiency of the operator OP, for example.
