Component Mounting Device FIG. 1 is a plan view schematically illustrating a partial configuration of a component mounting device. In the figure and the figures shown below, an XYZ orthogonal coordinate system including the substrate transport direction X, the width direction Y, and the vertical direction Z is shown as appropriate. The X-axis arrow side is referred to as one side, and the opposite side of the X-axis arrow is referred to as the other side as appropriate. The component mounting apparatus 1 has a schematic configuration in which a component supplied by a component supply unit 3 is transferred by a head unit 4 to a board loaded in a transport lane 2. More specifically, two transport lanes 2 extending in parallel with the substrate transport direction X, and two component supply units 3 provided on each side of the transport lane 2 in the width direction Y, The component mounting apparatus 1 includes four head units 4.

Each of the two transport lanes 2 has a common configuration, and carries a substrate into the substrate from the upstream side in the substrate transport direction X and stops at a predetermined stop position 20 (dashed line in FIG. 1); A board unloading operation for unloading the board that has received the component mounting at the stop position 20 to the downstream side in the board transport direction X is executed. At this time, each transport lane 2 has a configuration capable of stopping the substrate at each of two different stop positions 20 in the substrate transport direction X, for example. Each of the two transfer lanes 2 includes two transfer conveyors 21 extending in parallel with the board transfer direction X. In the component mounting apparatus 1, the four transfer conveyors 21 are arranged in the width direction Y. Out of the four transport conveyors 21, the outer two are fixed conveyors fixed in the width direction Y, and the inner two are movable conveyors movable in the width direction Y. Therefore, by moving the movable conveyor 21 in the width direction Y, the width of the transport lane 2 can be adjusted according to the width of the substrate.

Incidentally, the mode of substrate transfer in the two transfer lanes 2 is not limited to that illustrated in FIG. That is, FIG. 1 illustrates a case where two stop positions 20 are set in each of the two transfer lanes 2 and the substrate is transferred while setting a total of four stop positions 20. It is also possible to set one stop position 20 for each conveyance lane 2 and set a total of two stop positions 20. In addition, when the substrate width cannot be simultaneously executed in the two transfer lanes 2 due to the wide substrate width, the substrate transfer is executed only in one of the two transfer lanes, and the substrate is transferred in the other. Does not have to be executed.

The two component supply units 3 are arranged in the board conveyance direction X on each side of the conveyance lane 2 in the width direction Y, and the component mounting apparatus 1 is provided with a total of four component supply units 3. Each component supply unit 3 has a configuration in which a plurality of tape feeders 31 are arranged in the substrate transport direction X. Each tape feeder 31 has a schematic configuration in which a tape for storing small electronic components such as an integrated circuit (IC), a transistor, and a capacitor is wound around a reel, and the electronic components are intermittently fed from the reel. Supply electronic components. The type of feeder constituting the component supply unit 3 is not limited to a tape-type feeder, and may be a tray-type feeder that supplies electronic components while being placed on a tray.

Each of the four head units 4 has three mounting heads 5 arranged in the X direction, and a component supplied by the component supply unit 3 by sucking the component with a nozzle at the tip of each mounting head 5 Is transferred to the substrate which stops at the stop position 20. Further, the component mounting apparatus 1 is provided with a head driving mechanism 6 for moving the head unit 4. Specifically, four head drive mechanisms 6 are provided corresponding to the four component supply units 3 described above, and each head drive mechanism 6 has a corresponding component supply unit 3 on the inner side in the Y direction ( Adjacent from the transportation lane 2 side). The four head driving mechanisms 6 each drive one head unit 4.

Each head driving mechanism 6 has a configuration in which an X-axis beam 61 extending in the X direction while supporting the head unit 4 movably in the X direction is supported movably in the Y direction. An X-axis ball screw 62 attached to the head unit 4 and extending in the X direction and an X-axis servo motor 63 that rotationally drives the X-axis ball screw 62 are attached to the X-axis beam 61. When the X-axis servomotor 63 rotates the X-axis ball screw 62, the head unit 5 moves along the X-axis beam 61 in the X direction. Each head driving mechanism 6 includes a Y-axis ball screw 64 that is attached to the X-axis beam 61 and extends in the Y direction, and a Y-axis servo motor 65 that rotationally drives the Y-axis ball screw 64. Then, when the Y-axis servomotor 63 rotationally drives the Y-axis ball screw 64, the X-axis beam moves in the Y direction along with the head unit 5.

Each head drive mechanism 6 configured in this manner is in charge between the corresponding component supply unit 3 and the substrate at the stop position 20 by appropriately rotating the X-axis servo motor 63 and the Y-axis servo motor 65. The head unit 4 to be moved can be moved. As a result, the head unit 4 can pick up the components supplied by the component supply unit 3 with the mounting head 5 and transfer them to the substrate stopped at the stop position 20.

Also, for each of the four component supply units 3, a camera 68 and a nozzle changer 7 are disposed adjacent to each other from the inside in the Y direction (conveyance lane 2 side). Thus, the camera 68 and the nozzle changer 7 are provided between the component supply unit 3 and the transport lane 2 (in other words, the movement path of the head unit 4). The camera 68 is arranged in parallel with the vertical direction Z and faces upward, and is held by the head unit 4 passing through the upper side, or a position recognition mark member 41 (described later) attached to the head unit 4. 3). The nozzle changer 7 replaces nozzles attached to the mounting heads 5 of the head unit 4, and details thereof will be described later.

FIG. 2 is a side view showing an example of a head unit provided in the component mounting apparatus of FIG. 3 is a partial cross-sectional view in the X direction showing an example of a head unit provided in the component mounting apparatus of FIG. Next, the configuration of each head unit 4 will be described in detail with reference to FIGS. Since the four head units 4 have the same configuration, only one head unit 4 will be described here.

The head unit 4 includes three mounting heads 5 arranged in a straight line at a predetermined arrangement pitch Lh in the X direction. Each of the three mounting heads 5 has a schematic configuration in which a nozzle N is mounted on the lower end portion of the shaft 50 extending in the Z direction. Specifically, the mounting head 5 has eight shafts 50 arranged at an arrangement pitch equal to the circumferential direction centered on a central axis C51 parallel to the Z direction, and nozzles provided at the lower ends of the shafts 50. The nozzle N is detachably attached to the attachment portion 51.

In the nozzle mounting portion 51, a leaf spring 52 whose lower end is bent toward the shaft 50 is opposed to the outer periphery of the lower end of the shaft 50 with a gap. Then, when the nozzle N is pushed upward with respect to the nozzle mounting portion 51 in a state where the top of the nozzle N is fitted to the shaft 50 from the outside while the tip of the nozzle N is directed downward, the engagement provided on the outer periphery of the nozzle N The mating protrusion Ne enters the gap between the shaft 50 and the leaf spring 52 while pushing the lower end of the leaf spring 511 outward. As a result, the outer peripheral projection Ne of the nozzle N is engaged with the lower end portion of the leaf spring 52, and the nozzle N is mounted on the nozzle mounting portion 51 with its tip directed downward. The nozzle N thus mounted on the nozzle mounting portion 51 is held on the nozzle mounting portion 51 by the elastic force of the leaf spring 511. On the other hand, it is possible to remove the nozzle N from the nozzle mounting portion 51 by pulling the nozzle N mounted on the nozzle mounting portion 51 downward against the elastic force of the leaf spring 51. The nozzle N is formed with a flange Nf that protrudes laterally between the engagement protrusion Ne and the lower end (tip) of the nozzle N. The function of this Nf will be described later together with the nozzle changer 7.

A vent passage 53 extending in the Z direction from the nozzle mounting portion 51 is formed at the center of each shaft 50, while a nozzle hole Nv penetrating in the Z direction is formed at the center of the nozzle N, and the nozzle mounting The nozzle hole Nv of the nozzle N attached to the part 51 communicates with the air passage 53. Therefore, it is possible to cause the mounting head 51 to perform component mounting while adjusting the air pressure of the nozzle hole Nv through the air passage 53. Specifically, when holding the component supplied by the component supply unit 3, negative pressure is applied to the nozzle hole Nv while the tip of the nozzle N is in contact with the component, and the component is adsorbed to the tip of the nozzle N. Can do. Further, when placing a component on the substrate, a positive pressure is applied to the nozzle hole Nv, and the component can be instantaneously transferred from the nozzle N to the substrate. The mounting head 51 can raise and lower the eight shafts 50 individually. Therefore, the holding of the component from the component supply unit 3 and the placement of the component on the board can be executed by selectively raising and lowering the shaft 50 on which the nozzle N as the execution subject is mounted. Further, the mounting head 51 is a rotary mounting head that can integrally rotate the eight shafts 50 around the central axis C51. Therefore, the position of the nozzle N can be adjusted by appropriately rotating the eight shafts 50.

The rod-shaped position recognition mark members 41 extending in the Z direction are arranged on both outer sides in the X direction of the three heads 5 configured as described above. Each mark member 41 is fixed to the head unit 3 and is imaged by the camera 68 and used for position recognition of the head unit 3. Furthermore, the head unit 3 has a camera 43 that captures an image of a component adsorbed by the nozzle N, and an illumination 45 that illuminates the field of view of the camera 43. The camera 43 (the optical system 431 thereof) opposes the tip of the nozzle N mounted on the mounting head 5 from the Y direction, and images the component adsorbed by the nozzle N from the Y direction. Thus, the camera 43 is arranged on the Y direction side of the mounting head 5. Further, a rod-like reflecting member 47 is provided at the center of the eight nozzles N arranged in a circumferential shape in the mounting head 5. The light from the illumination 45 is reflected by the reflecting member 47, and the field of view of the camera 43 can be illuminated more brightly.

Nozzle changer The above is the outline of the component mounting apparatus 1. Next, the nozzle changer 7 will be described in detail. FIG. 4 is a perspective view showing an example of a nozzle changer. FIG. 4 shows a state in which the nozzles N are stored in all the nozzle storage portions of the nozzle changer 7. The nozzle changer 7 performs a mounting operation for mounting the nozzle N stored in the nozzle stocker 7 on the mounting head 5 and a storing operation for storing the nozzle N mounted on the mounting head 5 in the nozzle stocker 7. Specifically, four nozzle stockers 8 having a common configuration are arranged at an equal pitch in the Y direction on the upper part of the nozzle changer 7, and each nozzle stocker 8 performs a mounting operation and a storing operation. Is possible.

FIG. 5 is a perspective view showing an example of a nozzle stocker provided in the nozzle changer of FIG. FIG. 6 is a plan view showing an example of a nozzle stocker provided in the nozzle changer of FIG. The nozzle stocker 8 will be described with reference to FIGS. The nozzle stocker 8 has a rectangular parallelepiped stocker body 80 extending in the X direction, and a nozzle storage portion 81 that opens upward on the upper surface of the stocker body 80, and the nozzle N is inserted into and removed from the vertical direction Z. Store in the storage unit 81. Specifically, the nozzle N with the lower side (front end side) of the nozzle Nf inserted into the nozzle storage portion 81 and the upper side of the nozzle N protruding from the nozzle storage portion 81 (FIG. 4). The storage unit 81 stores the nozzle N. As shown in FIG. 5 and FIG. 6, on the upper surface of the stocker body 80, one nozzle storage unit 81U is configured from eight nozzle storage portions 81 arranged circumferentially at an equal pitch, and three more Nozzle storage units 81U are arranged in a straight line at an equal pitch in the X direction. The arrangement of the nozzle storage portions 81 corresponds to the arrangement of the nozzle mounting portions 51 in the head unit 4.

FIG. 7 is a diagram schematically showing the correspondence between the arrangement of nozzle mounting portions in the head unit and the arrangement of nozzle storage portions in the nozzle stocker. In the upper column of the figure, the arrangement of the nozzle mounting portions 51 in the head unit 4 is shown as viewed from below. In the lower column of the figure, the arrangement of the nozzle storage portions 81 in the nozzle stocker 8 is shown upward. The state seen from is shown. In the figure, a state in which the rotation angles of the respective mounting heads 5 are adjusted to be equal to each other is shown, and the nozzle mounting portion 51 is represented by a circular shape of the shaft 50 on which the nozzle N is mounted.

As described above, in the head unit 4, the three mounting heads 5 are linearly arranged in the X direction with the arrangement pitch Lh. Further, in each mounting head 5, eight nozzle mounting portions 51 are arranged circumferentially at an arrangement pitch Lo in the circumferential direction. The circumference O51 in which the eight nozzle mounting portions 51 are arranged has a radius Ro. Here, the circumference O51 is a virtual circle passing through the tip of the nozzle N mounted on each of the eight nozzle mounting portions 51.

On the other hand, in the nozzle stocker 8, three nozzle storage units 81U are linearly arranged in the X direction at an arrangement pitch equal to the arrangement pitch Lh. Further, in each nozzle storage unit 81U, eight nozzle storage portions 81 are arranged in the circumferential direction at an arrangement pitch equal to the arrangement pitch Lo. The circumference O81 where the eight nozzle storage portions 81 are arranged has the same radius as the radius Ro. Here, the circumference O81 is a virtual circle passing through the tip of the nozzle N accommodated in each of the eight nozzle mounting portions 81. Incidentally, when the nozzle storage portions 81 are arranged in this way, the nozzle storage portions 81 belonging to different nozzle storage units 81U adjacent in the X direction and having the same arrangement in each nozzle storage unit 81U have an arrangement pitch Lh in the X direction. Arranged in

As described above, the arrangement of the nozzle mounting portions 51 in the head unit 4 and the arrangement of the nozzle storage portions 81 in the nozzle stocker 8 are associated with each other. Therefore, if the rotation angle of each mounting head 5 of the head unit 5 is adjusted to match the arrangement angle of the nozzle mounting portion 51 and the arrangement angle of the nozzle storage portion 81 as shown in FIG. By making the nozzle stocker 8 face each other in the Z direction, the nozzle mounting portions 51 and the nozzle storage portions 81 can face each other in the Z direction in a one-to-one correspondence relationship. The above is an explanation of the correspondence between the arrangement of nozzle mounting portions in the head unit 4 and the arrangement of nozzle storage portions in the nozzle stocker 8. Returning to FIGS. 4 to 6, the description of the nozzle stocker 8 will be continued.

On the upper surface of the stocker body 80, bearing holes 801 that are recessed in a substantially disk shape are formed around each nozzle storage unit 81, and the eight nozzle storage portions 81 open at the bottom of the bearing holes 801. An annular shutter 82 having an outer diameter substantially the same as or slightly smaller than the inner diameter of the bearing hole 801 is fitted into each bearing hole 801 and provided to each nozzle housing unit 81U. In each nozzle storage unit 81, the center of the circumferential arrangement of the plurality of nozzle storage portions 81, the circular center of the bearing hole 801, and the center of the annular shape of the shutter 82 coincide with each other. 82 is rotatable around the nozzle housing unit 81 </ b> U while sliding between the inner wall of the bearing hole 801. In addition, on the upper surface of the stocker body 80, a presser plate 803 that protrudes to the inside of the bearing hole 801 and presses the shutter 82 from above is screwed around each bearing hole 801, and the shutter 82 falls off from the bearing hole 801. Is prevented.

Thus, the shutter 82 is provided for each of the three nozzle storage units 81U. Each shutter 82 has the following configuration, thereby restricting the insertion and removal of the nozzles N with respect to the eight nozzle storage portions 81 of the corresponding nozzle storage unit 81U. That is, the shutter 82 includes an annular peripheral portion 821 and eight projecting portions 822 that protrude inward from the peripheral portion 821. The peripheral edge portion 821 has an inner diameter larger than the diameter of a circumscribed circle circumscribing the eight nozzle storage portions 81 constituting the nozzle storage unit 81U, and surrounds the nozzle storage unit 81U from the outside. The eight protrusions 822 are arranged circumferentially at an equal pitch along the inner wall of the peripheral edge 821. That is, the same number of protrusions 822 are provided around the eight nozzle storage portions 81 constituting the nozzle storage unit 81U, and the eight nozzle storage portions 81 and the eight protrusion portions 822 are provided. It is associated. When the shutter 82 is rotated, each projection 822 is inserted into and removed from the insertion / removal restriction position Pr protruding from the insertion / removal path of the nozzle N with respect to the corresponding nozzle storage part 81 and the insertion / removal permission position Pp deviating from the insertion / removal path. Rotate between. Each protrusion 822 restricts insertion / removal of the nozzle N with respect to the corresponding nozzle storage portion 81 at the insertion / removal restriction position Pr, while permitting insertion / removal of the nozzle N with respect to the corresponding nozzle storage portion 81 at the insertion / removal permission position Pp. . 5 and 6, each protrusion 822 is located at the insertion / removal restriction position Pr.

Since the shutter 82 has the above-described configuration, by restricting or rotating the shutter 82 as appropriate, the insertion / removal of the nozzles N is collectively controlled with respect to the eight nozzle storage portions 81 corresponding to the shutter 82. be able to. That is, when the shutter 82 takes a rotating state (insertion / removal restriction state) in which each protrusion 822 is located at the insertion / removal restriction position Pr, the eight nozzle storage portions 81 corresponding to the shutter 82 have no nozzles. N insertion / removal is regulated collectively. On the other hand, when the shutter 82 takes a rotating state (insertion / removal permitted state) in which each protrusion 822 is positioned at the insertion / removal permission position Pp, the nozzles corresponding to the eight nozzle storage portions 81 corresponding to the shutter 82 are not nozzles. N insertion / removal is permitted at once.

Such rotation of the shutter 82 is performed via a crank plate 83 provided for each shutter 82 on the upper surface of the stocker body 80. That is, the shutter 82 has a pin 823 that protrudes upward from the peripheral edge 821. On the other hand, the crank plate 83 is provided adjacent to the bearing hole 801 in which the shutter 82 is fitted, and is configured to be rotatable while being engaged with the pin 823 of the shutter 82. Specifically, the crank plate 83 has an engaging portion 831 protruding inside the bearing hole 801, and engages with the pin 823 by a long hole 832 that penetrates the engaging portion 831 in the Z direction. Therefore, when the crank plate 83 rotates, the shutter 82 rotates in conjunction with the crank plate 83. The length of the long hole 832 is longer than the outer diameter of the pin 823, and play is provided between the long hole 832 and the pin 823 so that the shutter 82 can be smoothly interlocked with the crank plate 83. Has been.

Thus, on the upper surface of the stocker body 80, the shutter 82 and the crank plate 83 are provided for each of the three nozzle storage units 81U. Further, the nozzle stocker 8 has a mechanism for collectively switching the state of the three shutters 82 to either the insertion / removal restricted state or the insertion / removal permitted state by rotating the three crank plates 83 at a time. It has. That is, the guide groove 805 extending in the X direction is formed on the side surface in the Y direction of the stocker body 80. The guide groove 805 extends from directly below the shutter 82 located at one end (left side in FIG. 5) in the X direction, and opens at the end of the stocker body 80 on the other side (right side in FIG. 5) in the X direction. . A slider 84 that is longer than the guide groove 805 in the X direction is fitted into the guide groove 805. The slider 84 is provided so as to be movable in the X direction along the guide groove 805 while partially protruding from the end of the guide groove 805 on the other side in the X direction (right side in FIG. 5).

Furthermore, the slider 84 has a pin 841 protruding upward, which is disposed below each of the three crank plates 83 arranged in the X direction. Thus, each of the three pins 841 arranged in the X direction engages with a notch 833 formed in the clamp plate 83 positioned above. Therefore, when the slider 84 is moved in the X direction, the three crank plates 83 that engage with the slider 84 via the three pins 841 rotate at once, and the three shutters 82 rotate at the same time. Move. By moving the slider 84 in the X direction in this way, the three shutters 82 interlocked with the slider 84 are rotated at once, and the three shutters 82 are set in either the insertion / removal restricted state or the insertion / removal permitted state. The state can be switched at once.

FIG. 8 is a plan view showing an example of the switching operation between the insertion / removal restriction state and the insertion / removal permission state, and illustrates a state in which the nozzle N is stored in each nozzle storage unit 81 of the nozzle storage unit 81U. In the figure, the configuration related to one nozzle storage unit 81U is representatively shown, but the configuration related to three nozzle storage units 81U belonging to the same nozzle stocker 8 performs the same operation collectively. .

As shown in the upper column of the figure, in the insertion / removal restricted state, the pin 841 is moved to one side Xl in the X direction along with the slider 84. Therefore, the crank plate 83 is in a state of being rotated clockwise Rf, and the shutter 82 is in a state of being rotated counterclockwise Rb. As a result, each protrusion 822 is positioned at the insertion / removal restriction position Pr protruding in the insertion / removal path of the nozzle N with respect to the nozzle storage portion 81, and restricts the insertion / removal of the nozzle N into the nozzle storage portion 81. In particular, as shown in FIG. 8, when the nozzle N is inserted into the nozzle storage portion 81, each protrusion 822 positioned at the insertion / removal restriction position Pr is a width of the nozzle Nf of the nozzle N stored in the nozzle storage portion 81. Positioned immediately above, the removal of the nozzle N from the nozzle storage portion 81 is restricted.

As shown in the lower column of the figure, in the insertion / removal permission state, the pin 841 is moved to the other side Xr in the X direction along with the slider 84. Therefore, the crank plate 83 is in a state of being rotated counterclockwise Rb, and the shutter 82 is in a state of being rotated clockwise Rf. As a result, each protrusion 822 is positioned at an insertion / removal permission position Pp that deviates from the insertion / removal path of the nozzle N with respect to the nozzle storage unit 81, and permits insertion / removal of the nozzle N into / from the nozzle storage unit 81. In particular, as shown in FIG. 8, when the nozzle N is inserted into the nozzle storage portion 81, each protrusion 822 positioned at the insertion / removal permission position Pp is the width of the nozzle N stored in the nozzle storage portion 81. The nozzle N is removed from just above, and the removal of the nozzle N from the nozzle storage portion 81 is permitted.

As described above, in the nozzle stocker 8, the sliders 84 are moved to the X1 side or the Xr side in the X direction, whereby the shutters 82 can be collectively rotated to the counterclockwise side Rb or the clockwise side Rf. . Therefore, by simply operating the slider 84, switching from the insertion / removal permitted state to the insertion / removal prohibited state or switching from the insertion / removal prohibited state to the insertion / removal permitted state can be performed collectively for each shutter 82. it can.

Returning to FIGS. 4 to 6, the description will be continued. The stocker body 80 incorporates an elastic member (not shown) such as a spring for urging the slider 84 to one side in the X direction (left side in FIG. 5), and each shutter 82 is inserted and removed by this elastic member. It is urged in the rotation direction Rb that is in the restricted state. On the other hand, the slider 84 has a shutter operation portion 843 protruding upward at a portion protruding from the stocker body 80 to the other side in the X direction (right side in FIG. 5). Therefore, by operating the shutter operation unit 843, the slider 84 can be moved in the X direction against the urging force of the elastic member. However, the stocker body 80 includes a stopper 85 provided on the moving path of the slider 84 on the other side in the X direction of the slider 84 (the right side in FIG. 5). Therefore, when the slider 84 hits the stopper, further movement of the slider 84 against the urging force is restricted. In addition, a ring 84a that is rotatable about a rotation axis parallel to the Y direction is attached to the end of one side Xl of the slider 84 in the X direction. Therefore, the slider 84 can be moved to the other side Xr in the X direction by pressing the ring 84a to the other side Xr in the X direction.

The slider 84 is formed thick in the Y direction in the thick portion 845 provided with the pins 841. The thick portion 845 protrudes from the guide groove 805 in the Y direction, and moves as the slider 84 moves. On the other hand, a cover member 807 that covers the guide groove 805 is screwed to the side surface of the stocker body 80 while avoiding the movement range of the thick portion 845 of the slider 84. The cover member 807 prevents the slider 84 from falling off the guide groove 805.

By the way, by using the nozzle take-out device 9 (FIG. 13) described later, the nozzles N can be taken out from the nozzle storage portion 81 of the nozzle stocker 8 in a lump. Therefore, guide holes 86 extending in the Z direction are formed at both ends of the nozzle stocker 8 in order to facilitate the mutual positioning of the nozzle stocker 8 and the nozzle extraction device 9 during the nozzle extraction operation.

The above is the details of the configuration of the nozzle stocker 8 provided in the nozzle changer 7 of FIG. Next, a stocker lifting mechanism 71 that lifts and lowers the nozzle stocker 8 will be described with reference to FIGS. 4, 9, and 10. Here, FIG. 9 is a side view showing an example of the nozzle changer of FIG. 4, and FIG. 10 is a front view showing an example of the nozzle changer of FIG. On the upper surface of the base 70 of the nozzle changer 7, four stocker raising / lowering mechanisms 71 having a common configuration are arranged at equal pitches in the Y direction, and four nozzles are disposed above the stocker raising / lowering mechanism 71. Stockers 8 are arranged at equal pitches in the Y direction. The arrangement pitch of the stocker elevating mechanism 71 and the arrangement pitch of the nozzle stocker 8 are equal to each other, and the four stocker elevating mechanisms 71 and the four nozzle stockers 8 are associated with each other. And each stocker raising / lowering mechanism 71 raises / lowers the nozzle stocker 8 just provided correspondingly.

The support frame 710 that forms the skeleton of the stocker lifting mechanism 71 is erected on the base 70 and extends in the Z direction. The stocker elevating mechanism 71 includes a Z-axis cylinder 712 fixed to the lower portion of the support frame 710 and an elevating plate 713 provided on the upper portion of the support frame 710 so as to be movable up and down. The Z-axis cylinder 712 is a rod cylinder (air cylinder) that advances and retracts the cylinder rod 712a in the Z direction by air. The Z-axis cylinder 712 is supplied with air from an air supply device 701 housed in the lower part of the base 70 via an air hose 702. The cylinder rod 712a is moved up and down. The elevating plate 713 is supported by a guide member 714 fixed to the upper part of the support frame 710 so as to be movable up and down. The upper part of the cylinder rod 712 a of the Z-axis cylinder 712 is attached to the lift plate 713 by a joint 715. Therefore, the elevating plate 713 can be moved up and down by the Z-axis cylinder 712. The stocker elevating mechanism 71 has a support bottom plate 716 that supports the nozzle stocker 8 from below, and the upper portion of the elevating plate 713 is fixed to the support bottom plate 716. Therefore, the nozzle stocker 8 moves up and down together with the lift plate 713.

Such a stocker raising / lowering mechanism 71 can raise and lower the corresponding nozzle stocker 8 by moving the cylinder rod 712a of the Z-axis cylinder 712 forward and backward in the Z direction. In the nozzle changer 7, a stocker lifting mechanism 71 is individually provided for each of the four nozzle stockers 8. Therefore, the four nozzle stockers 8 can be raised and lowered individually.

Furthermore, the nozzle changer 7 has a shutter operation mechanism 73 for operating the shutter 82 of the raised nozzle stocker 8 by operating the shutter operation portion 843 of the raised nozzle stocker 8 among the four nozzle stockers 8. The shutter operation mechanism 73 is disposed on the other side in the X direction of the four nozzle stockers 8 (the right side in FIG. 10), and is attached to the support frame 710 via the connection frame 75. As will be described below, the shutter operation mechanism 73 has a schematic configuration in which a clutch member 731 facing the shutter operation portion 843 of the nozzle stocker 8 from above is driven in the X direction by an X-axis cylinder 732.

The connection frame 75 includes a mounting plate 75a provided parallel to the YZ plane on the other side in the X direction of the four nozzle stockers 8 and the support frame 710 (right side in FIG. 10), and both sides of the mounting plate 75a in the Y direction. There are two bent flat plates 75b bent in the X direction toward the support frame 710, and these bent flat plates 75b are screwed to the support frames 710 located at both ends in the Y direction. The frame member 730 of the shutter operation mechanism 73 is attached to the upper end of the attachment flat plate 75a and protrudes from the attachment flat plate 75a to the other side in the X direction (the right side in FIG. 10). The frame member 730 has a flat plate shape parallel to the XY plane, and is positioned at the center of the arrangement of the four nozzle stockers 8 in the Y direction.

The clutch member 731 is attached to the upper surface of the frame member 730 via the X-axis guide mechanism 733, and is movable in the X direction. Specifically, the X-axis guide mechanism 733 includes an X-axis rail 733a fixed to the upper surface of the frame member 730, and an X-axis slider 733b movable in the X direction along the X-axis rail 733a. A clutch member 731 is screwed to the shaft slider 733b. The clutch member 731 includes a first extending plate 731a, a second extending plate 731b, and an engaging claw 731c. The first extending plate 731a is a plate extending in the X direction from the X-axis slider 733b toward the nozzle stocker side 8, and is bent in a stepped manner at a portion protruding from the X-axis slider 733b. The second extending plate 731b is a plate extending in the X direction from the first extending plate 731a to above the four nozzle stockers 8. The second extending plate 731b has a width wider than the arrangement of the four shutter operation units 843 in the Y direction, and faces the four shutter operation units 843 arranged in the Y direction from above. The engaging claw 731c is bent downward from the tip in the X direction on the nozzle stocker side 8 of the second extending plate 732b, and has the same width as the second extending plate 731b in the Y direction.

The X-axis cylinder 732 is attached to the lower surface of the frame member 730 and has a cylinder rod 732a extending in the X direction toward the nozzle stocker 8 side. The cylinder rod 732a extends through the through hole (not shown) provided in the attachment flat plate 75a of the connection frame 75 in the X direction and extends from the attachment flat plate 75a to the nozzle stocker 8 side. The X-axis cylinder 732 is a rod cylinder (air cylinder) that advances and retracts the cylinder rod 732a in the X direction by air, and receives supply of air from the air supply device 701 housed in the lower part of the base 70 via the air hose 703. To move the cylinder rod 732a. The tip of the cylinder rod 732 a on the nozzle stocker 8 side is connected to an engagement flat plate 735 that engages with the clutch member 731. Specifically, rod members 736 that are spaced apart in the X direction and extend in the Y direction are fixed to the bottom surface of the clutch member 731, and the engaging flat plate 735 is free to play between the rod members 736. And is engaged with the clutch member 731. Therefore, by moving the cylinder rod 732a of the X-axis cylinder 732 forward and backward in the X direction, the clutch member 731 can be moved in the X direction and brought into contact with and separated from the nozzle stocker 8.

The thus configured clutch member 731 of the shutter operation mechanism 73 selectively engages with the shutter operation portion 843 of the nozzle stocker 8 raised by the stocker elevating mechanism 71, and the shutter 82 of the nozzle stocker 8 raised. Can be operated. Such an operation will be described with reference to FIGS. 11 and 12 together. Here, FIG. 11 is a perspective view illustrating a state where one nozzle stocker 8 is selectively raised, and FIG. 12 is a front view illustrating a state where one nozzle stocker is selectively raised. is there. In the example shown in FIGS. 11 and 12, only the leftmost nozzle stocker 8 in FIG. 4 is raised, the other nozzle stockers 8 are lowered, the cylinder rod 732a extends to the nozzle stocker 8 side, and the clutch member 731 is Close to the nozzle stocker 8.

The above-described stocker raising / lowering mechanism 71 raises and lowers the nozzle stocker 8 between the raised position Pu and the lowered position Pd below the raised position Pu. On the other hand, the second extending plate 731b of the clutch member 731 faces the operation portion 843 of each of the four nozzle stockers 8 from above. The height of the clutch member 731 is set to a height at which the second extending plate 731 is positioned slightly above the upper end of the operation portion 843 of the nozzle stocker 8 at the raised position Pu. Specifically, a clearance less than the length of the engaging claw 731c of the clutch member 731 is vacant between the upper end of the operation portion 843 of the nozzle stocker 8 at the raised position Pu and the second extending plate 731b of the clutch member 731. ing. Further, in a state where the cylinder rod 732a is extended, the engaging claw 731c of the clutch member 731 is located on the one side Xl in the X direction further than the operation portion 843 pushed to the one side Xl in the X direction by the urging force. . Accordingly, the operation portion 843 of the nozzle stocker 8 located at the raised position Pu is located at the lowered position Pd while the engaging claw 731c of the clutch member 731 is engaged on one side Xl in the X direction. The engaging claw 731c of the clutch member 731 is disengaged downward from the operation portion 843 of the nozzle stocker 8 and is not engaged.

In such a nozzle changer 7, the shutter operation mechanism 73 can operate the nozzle stocker 8 at the raised position Pu via the clutch member 731. That is, when the shutter operating mechanism 73 operates the X-axis cylinder 732 and contracts the cylinder rod 732a, the operation portion 843 of the nozzle stocker 8 is pulled to the other side Xr in the X direction by the clutch member 731. As a result, the slider 84 moves to the other side Xr in the X direction, and the shutters 82 of the nozzle stocker 8 are collectively switched from the insertion / removal prohibited state to the insertion / removal permitted state. Further, when the shutter operating mechanism 73 operates the X-axis cylinder 732 and extends the cylinder rod 732a, the slider 84 is moved in one direction in the X direction by the urging force as the clutch member 731 moves to one side X1 in the X direction. Moving to the side Xl, the shutters 82 of the nozzle stocker 8 are collectively switched from the insertion / removal permitted state to the insertion / removal prohibited state. Thus, the clutch member 731 can switch the shutters 82 of the nozzle stocker 8 at the raised position Pu between the insertion / removal permitted state and the insertion / removal prohibited state. On the other hand, the operation portion 843 of the nozzle stocker 8 at the lowered position Pd does not engage with the clutch member 731. Therefore, the shutters 82 of the nozzle stocker 8 at the lowered position Pd are maintained in the insertion / removal prohibited state regardless of the operation of the shutter operation mechanism 73.

That is, the nozzle changer 7 can not only simply move the nozzle stocker 8 up and down by the stocker lifting mechanism 71 but also control the formation and blocking of the power transmission path between the shutter 82 of the nozzle stocker 8 and the shutter operation mechanism 73. it can. That is, if the nozzle stocker 8 is raised to the raised position Pu by the nozzle stocker lifting mechanism 71, a power transmission path between the nozzle stocker 8 and the shutter operation mechanism 73 can be formed. Further, if the nozzle stocker 8 is lowered to the lowered position Pd by the nozzle stocker raising / lowering mechanism 71, the power transmission path between the nozzle stocker 8 and the shutter operation mechanism 73 can be interrupted.

Nozzle removal device The above is an example of the component mounting device 1 including the nozzle changer 7. Next, the nozzle take-out device used when taking out the nozzle N accommodated in the nozzle changer 7 from the nozzle changer 7 will be described. FIG. 13 is a perspective view showing an example of a nozzle take-out device to which the present invention can be applied. FIG. 14 is a plan view of the nozzle take-out device shown in FIG. FIG. 15 is a bottom view of the nozzle take-out device shown in FIG.

The nozzle take-out device 9 has a schematic configuration in which an engagement member 91 that is detachably engaged with the nozzle N is supported by a rectangular parallelepiped support member 90 that is long in the longitudinal direction Dx and short in the width direction Dy. Yes. The operator brings the nozzle take-out device 9 closer to the nozzle stocker 8 from the engagement / disengagement direction Dz and engages the engagement member 91 of the nozzle take-out device 9 with the nozzle N accommodated in the nozzle stocker 8. The nozzle N can be taken out from the nozzle stocker 8 by separating the nozzle take-out device 9 from the nozzle stocker 8 in the engaging / disengaging direction Dz. 13 to 15 and the drawings shown below, the side on which the nozzle take-out device 9 is moved when the nozzle take-out device 9 is brought close to the nozzle stocker 8 is represented as the approach side Dz (+) in the engagement / disengagement direction Dz. The side on which the nozzle take-out device 9 is moved when the nozzle take-out device 9 is moved away from the nozzle stocker is represented as a separated side Dz (−) in the engagement / disengagement direction Dz. In addition, an orthogonal coordinate system including a longitudinal direction Dx, a width direction Dy, and an engagement / disengagement direction Dz is shown as appropriate.

On the approaching side Dz (+) surface of the support member 90, three recesses 901 are arranged in a straight line at equal pitches in the longitudinal direction Dx. Further, the support member 90 is formed with a cutout portion 902 cut out in the width direction Dy in the middle of the longitudinal direction Dx, specifically, between the concave portion 901 at one end and the concave portion 901 at the center. The recess 901 has a circular shape in a plan view and opens on the approaching side Dz (+) in the engagement / disengagement direction Dz. In the recess 901, eight engaging members 91 are arranged at equal pitches around the circumference to constitute an engaging unit 91U. Since the engaging units 91U are provided in the respective recesses 901, three engaging units 91U are linearly arranged at equal pitches in the longitudinal direction Dx on the surface on the approaching side Dz (+) of the support member 90. Will be. Such an arrangement of the engaging members 91 corresponds to the arrangement of the nozzle storage portions 81 in the nozzle stocker 8.

That is, as described above with reference to FIG. 7, in the nozzle stocker 8, three nozzle storage units 81U are linearly arranged in the X direction with the arrangement pitch Lh. Further, in each nozzle storage unit 81U, eight nozzle storage portions 81 are arranged circumferentially at an arrangement pitch Lo in the circumferential direction. The circumference O81 in which the eight nozzle storage portions 81 are arranged has a radius Ro. On the other hand, in the nozzle take-out device 9, as shown in FIG. 14, three engagement units 91U are linearly arranged in the X direction at an arrangement pitch equal to the arrangement pitch Lh. Further, in each engagement unit 91U, eight engagement members 91 are arranged in the circumferential direction with an arrangement pitch equal to the arrangement pitch Lo. The circumference O91 where the eight engaging members 91 are arranged has the same radius as the radius Ro. Here, the circumference O91 is a virtual circle passing through the tip of the nozzle N engaged with each of the eight engaging members 91.

As described above, the arrangement of the nozzle storage portions 81 in the nozzle stocker 8 and the arrangement of the engaging members 91 in the nozzle take-out device 9 are associated with each other. Therefore, the engaging member 91 and each nozzle housing are accommodated by making the approaching side Dz (+) of the nozzle take-out device 9 face the upper surface of the nozzle stocker 8 while making the engaging / disengaging direction Dz of the nozzle take-out device 9 parallel to the Z direction. The portions 81 can be opposed to each other in the Z direction with a one-to-one correspondence. Furthermore, the nozzle storage device 81 of the nozzle stocker 8 is brought closer to the nozzle stocker 8 from the engagement / disengagement direction Dz by making the engagement members 91 and the nozzle storage portions 81 face each other. The engaging members 91 of the nozzle take-out device 9 can be collectively engaged with the nozzles N accommodated therein. The above is the description of the correspondence between the arrangement of the nozzle storage portions 81 in the nozzle stocker 8 and the arrangement of the nozzle storage portions in the nozzle take-out device 9.

A rubber member 92 having a circular shape in plan view is screwed to the center of each recess 901 of the support member 90. The rubber member 92 has a smaller diameter than the inscribed circle of the plurality of engaging members 91 arranged in a circumferential shape, and the eight engaging members 91 surrounding the rubber member 92 and the rubber member 92 are included. There is a gap between them. The rubber member 92 slightly protrudes toward the approach side Dz (+) in the engagement / disengagement direction Dz with respect to the recess 901. The engagement member 91 protrudes greatly toward the approaching side Dz (+) in the engagement / disengagement direction Dz with respect to the recess 901 and the rubber member 91, respectively.

The engagement member 91 is formed with a vent hole 911 penetrating in the engagement / disengagement direction Dz. The air hole 911 communicates with the nozzle hole Nv of the nozzle N that engages with the engaging member 91 through which the air hole 911 passes. Further, in the support member 90, an air blowing port 93 (FIG. 15) communicating with the vent holes 911 of each of the eight engaging members 91 provided in the concave portion 901 is provided in the bottom portion of the concave portion 901. The air outlet 93 is provided for each of the three recesses 901.

Further, the nozzle take-out device 9 is provided at both ends of the support member 90 in the longitudinal direction Dy and protrudes toward the approaching side Dz (+) in the engagement / disengagement direction Dz, or at the end of the support member 90 in the longitudinal direction Dy. An operating member 96 is provided. The guide pins 95 are provided corresponding to the guide holes 86 of the nozzle stocker 8. More specifically, in a state where the nozzle take-out device 9 is opposed to the nozzle stocker 8, each guide pin is opposed to each guide hole 86 and can be inserted and removed in the Z direction. It is provided in the stocker body 80.

The operation member 96 supports the pressing button 961 and the contact lever 962 on the rotating plate 960 while rotatably supporting a flat rotating plate 960 around a rotating shaft C96 provided at the corner of the support member 90. The schematic configuration provided in FIG. The rotating flat plate 960 is a flat plate provided along the surface on the separation side Dz (−) of the support member 90, and has a window 940 a at a portion facing the air outlet 93. The window 960a exposes the air outlet 93 without being hidden by the rotating flat plate 960. The push button 961 is provided on the longitudinal direction Dx side of the rotation axis C96 and faces the notch 902 of the support member 90 from the width direction Dy, and with respect to the notch 902 as the rotating plate 960 rotates. Insert and remove. The contact lever 962 is provided adjacent to the side surface of the support member 90 on the opposite side of the rotation axis C96 in the width direction Dy, and protrudes greatly from the support member 90 to the approach side Dz (+) in the engagement / disengagement direction Dz. Yes. The abutment lever 962 is displaced in the rotation direction Dr along with the rotation of the rotation flat plate 960, thereby being displaced to the inner side Dr (+) of the support member 90 in the longitudinal direction Dx or the outer side of the support member 90. It can be displaced to Dr (-).

Since the contact lever 962 and the press button 961 are connected via the rotating flat plate 960, the press button 961 comes out of the notch portion 902 while the contact lever 962 is displaced inwardly to Dr (+). The pressing member 961 enters the notch 902 in a state where the contact lever 962 is displaced outward Dr (−). Further, the operation member 96 is urged in a direction in which the contact lever 962 is displaced inwardly to Dr (+) by an urging member (not shown) provided on the rotating shaft C96. Therefore, when the operator pushes the pressing button 961 against the urging force into the notch 902, the contact lever 962 is displaced outward Dr (−), while when the operator releases the pressing button 961, the contact lever 962 is moved. It is displaced inward Dr (+) by the urging force.

Then, the nozzle take-out device 9 having the configuration shown in FIGS. 13 to 15 can hold the nozzle N taken out from the nozzle stocker 8 as shown in FIG. FIG. 16 is a cross-sectional view showing a nozzle take-out device in which a nozzle is taken out from the nozzle storage portion. In a state where the nozzle N is housed in the nozzle stocker 8, the tip Nt of the nozzle N faces downward and fits in the nozzle housing portion 81, while the nozzle hole Nv of the nozzle N opens upward on the opposite side of the tip Nt. Yes. Therefore, when the engagement / disengagement direction Dz of the nozzle take-out device 9 is made to coincide with the Z direction, and the nozzle take-out device 9 is brought close to the nozzle stocker 8 from above, the nozzle hole Nv of the nozzle N accommodated in the nozzle stocker 8 becomes the nozzle The engagement member 91 of the take-out device 9 is fitted from the outside. At this time, the nozzle N is sandwiched between the engaging member 91 and the rubber member 92 at the periphery of the nozzle hole Nv, and is pushed to the engaging member 91 by the elastic force of the rubber member 92. As a result, the nozzle N is held by the engaging member 91 by the frictional force acting between the nozzle N and the engaging member 91 and the frictional force acting between the nozzle N and the rubber member 92.

Also, the support member 90 is provided with the air blowing port 93 described above. Specifically, as shown in FIG. 16, the air blowing port 93 includes an opening 931 that opens to the bottom surface (the surface on the separation side Dz (−)) of the support member 90 at the center of the recess 901, and the opening 931 and the engaging member 91. It is comprised with the connection path 932 which connects the vent hole 911. FIG. The connection path 932 extends from the opening 931 toward the engagement / disengagement direction Dz into the support member 90, and then radially diverges in a direction orthogonal to the engagement / disengagement direction Dz to the vent 911 of each engagement member 91. It arrives. In addition, the nozzle hole Nv of the nozzle N engaged with the engaging member 91 communicates with the vent hole 911 of the engaging member 91. Therefore, the operator can perform flushing cleaning for flushing air to the nozzle hole Nv of the nozzle N held by the engaging member 91 by blowing air into the opening 931 of the air blowing port 93 (air blow). it can.

FIG. 17 is a perspective view showing an example of an operation when taking out the nozzle from the nozzle changer using the nozzle take-out device. In the figure, there is a case where the nozzles N stored in the second nozzle stocker 8 from the back are collectively extracted by the nozzle extraction device 9 from the state where the nozzles N are stored in all the nozzle storage portions 81 of the nozzle changer 7. Illustrated. In addition, each process of the figure is performed by the operator.

In the approach step shown at the top of the figure, the operator sets the approach side Dz (+) of the nozzle take-out device 9 to the second nozzle stocker from the back while making the engagement / disengagement direction Dz of the nozzle take-out device 9 parallel to the Z direction. 8 is opposed to the upper surface. Thereby, the nozzle N accommodated in each nozzle accommodating part 81 of the 2nd nozzle stocker 8 and each engaging member 91 of the nozzle taking-out apparatus 9 mutually oppose in a Z direction by the one-to-one correspondence. From the state in which each nozzle N and each engagement member 91 are thus opposed, the operator moves the nozzle take-out device 9 to the approach side Dz (+) in the engagement / disengagement direction Dz and causes the nozzle stocker 8 to move the nozzle take-out device. 9 is approached from the engagement / disengagement direction Dz. As a result, the engaging members 91 of the nozzle take-out device 9 are collectively engaged with the nozzles N stored in the nozzle storing portions 81 of the nozzle stocker 8 as in the engaging step shown in the center of FIG. Match.

Incidentally, two guide pins 95 of the guide pin 95 of the nozzle take-out device 9 are inserted into the two guide holes 86 of the nozzle stocker 8 in the middle of the approach of the nozzle take-out device 9 to the nozzle stocker 8. As a result, in the state where the nozzle N of the nozzle stocker 8 and the engagement member 91 of the nozzle take-out device 9 are positioned with respect to each other in the XY plane, the approach / engagement of the engagement member 91 with each nozzle N is executed. Further, the contact lever 962 of the nozzle take-out device 9 contacts a ring 84a provided on the slider 84 of the nozzle stocker 8 from one side Xl in the X direction. At this time, since the urging force for urging the contact lever 96 is set to be larger than the urging force for urging the slider 84, the contact lever 96 pushes the slider 84 to the other side Xr in the X direction. The restriction of insertion / removal of the nozzle N by the shutter 82 is released (that is, the state of the shutter 82 is switched from the insertion / removal restriction state to the insertion / removal permission state). Therefore, in a state where the engagement members 91 are engaged with the nozzles N, the nozzles N can be taken out from the nozzle stocker 8.

Subsequently, the operator moves the nozzle take-out device 9 from the nozzle stocker 8 to the separation side Dz (−) in the engagement / disengagement direction Dz, and separates the nozzle take-out device 9 from the nozzle stocker 8 in the engagement / disengagement direction Dz. As a result, the nozzles N that can be removed from the nozzle accommodating portion 81 are removed from the nozzle accommodating portion 81 of the nozzle stocker 8 while being held by the engaging member 91 as in the separation step shown at the bottom of FIG. It is. Incidentally, the length of the contact lever 96 in the Z direction is set so that the restriction of the insertion / removal of the nozzle N by the shutter 82 is released until the removal of the nozzle N from the nozzle storage portion 81 is completed. In this way, the nozzle extraction operation for extracting the nozzle N from the nozzle exchanger 7 using the nozzle extraction device 9 is completed. As shown in the figure, since the engaging member 91 engages with the nozzle N from the opposite side of the tip Nt, the tip of the nozzle N taken out from the nozzle storage portion 81 and held in the nozzle take-out device 9 is It will be exposed.

FIG. 18 is a perspective view showing an example of work when the nozzle is stored in the nozzle changer using the nozzle take-out device. In the figure, from the state where the nozzles N are not stored in all the nozzle storage parts 81 of the second nozzle stocker 8 from the back of the nozzle changer 7, the nozzles N are collectively added to all the nozzle storage parts 81 of the nozzle stocker 8. The case of storing is illustrated. In addition, each process of the figure is performed by the operator.

In the approach step shown at the top of the figure, the operator sets the approach side Dz (+) of the nozzle take-out device 9 to the second nozzle stocker from the back while making the engagement / disengagement direction Dz of the nozzle take-out device 9 parallel to the Z direction. 8 is opposed to the upper surface. At this time, the nozzle N is previously engaged with each engaging member 91 of the nozzle take-out device 9 by the operator. Thereby, each nozzle accommodating part 81 of the 2nd nozzle stocker 8 and the nozzle N hold | maintained at each engaging member 91 of the nozzle extraction apparatus 9 mutually oppose in a Z direction by the one-to-one correspondence. Thus, from the state in which each nozzle accommodating portion 81 and each nozzle N are opposed to each other, the operator moves the nozzle take-out device 9 to the approaching side Dz (+) in the engagement / disengagement direction Dz and causes the nozzle stocker 8 to move the nozzle take-out device. 9 is approached from the engagement / disengagement direction Dz. As a result, the nozzles N held by the nozzle take-out device 9 are collectively stored in the nozzle storage portions 81 of the nozzle stocker 8 as in the storage process shown in the center of FIG.

Further, in the storing step shown in the figure, after the storage of the nozzle N in the nozzle storing portion 81 is completed, the operator pushes the pressing button 961 into the cutout portion 902 and moves the contact lever 962 to the outer side Dr (−). Displace. As a result, the shutter 82 of the nozzle stocker 8 enters the insertion / removal restriction state, and the removal of the nozzles N stored in the nozzle storage portions 81 from the nozzle storage portions 81 is restricted.

Subsequently, the operator moves the nozzle removal device 9 from the nozzle stocker 8 to the separation side Dz (−) in the engagement / disengagement direction Dz while pushing the push button 961 into the notch 902, and removes the nozzle from the nozzle stocker 8. The device 9 is separated in the engagement / disengagement direction Dz. As a result, as in the separation step shown at the bottom of the figure, each nozzle N that is restricted from being taken out from the nozzle storage portion 81 is detached from the engagement member 91 and remains in the nozzle storage portion 81 of the nozzle stocker 8. Thus, the nozzle storing operation for storing the nozzle N in the nozzle changer 7 using the nozzle take-out device 9 is completed.

As described above, in this embodiment, the nozzle N is extracted using the nozzle extraction device 9 provided with the engagement member 91 that is detachably engaged with the nozzle N.

Therefore, since the tip Nt of the nozzle N taken out by the nozzle take-out device 9 can be visually checked, for example, an appropriate cleaning method can be easily determined according to the state of contamination of the nozzle tip Nt, and convenience for the operator is improved.

Further, the nozzle take-out device 9 is provided with a guide pin 95 that is detachably fitted into a guide hole 86 provided in the nozzle stocker 8. When the guide pin 95 is fitted into the guide hole 86, the engagement member 91 is aligned with the nozzle N stored in the nozzle storage portion 81. In such a configuration, by engaging the guide pin 95 in the guide hole 86 of the nozzle stocker 8, the engagement member 91 can be aligned with the nozzle N stored in the nozzle storage portion 81. The operation of engaging 91 with the nozzle N can be facilitated.

Incidentally, in the nozzle changer 7, the nozzle stocker 8 appropriately regulates the removal of the nozzle N from the nozzle storage portion 81. Specifically, the restriction of the removal of the nozzle from the nozzle storage portion 81 by the nozzle stocker 8 is controlled by the position of the slider 84 (control member). In such a case, it is not possible to remove the nozzle N from the nozzle storage portion 81 unless the removal restriction is released. Therefore, the nozzle take-out device 9 is provided with an operation member 96 for operating the slider 84. The operating member 96 operates the slider 84 until the engaging member 91 engaged with the nozzle N of the nozzle storage portion 81 is separated from the nozzle stocker 8 and the removal of the nozzle N from the nozzle storage portion 81 is completed. Thus, the restriction on the removal of the nozzle N from the nozzle storage portion 81 is released. In such a configuration, until the engagement member 91 engaged with the nozzle N of the nozzle storage portion 81 is separated from the nozzle stocker 8 and the removal of the nozzle N from the nozzle storage portion 81 is completed, the nozzle extraction device By the function of the operation member 96 provided in 9, the restriction of taking out the nozzle N is released. As a result, the worker can take out the nozzle N without releasing the restriction himself, and the workability for the worker is improved.
