Description

[Technical Field]

[0001] The present invention relates to a reel holding device that holds a reel that houses a carrier tape in which components are enclosed, and a component mounting device that is configured to include this reel holding device. [Background technology]

[0002] Conventionally, component mounting devices are known that manufacture mounted boards by supplying components using a component supply unit and transferring the components to a board using a work head. There are various types of component supply units, but a tape feeder type that transports a carrier tape containing components and supplies the components to a component supply port is widely used. Because a tape feeder draws in and transports the carrier tape unwound from a reel, the component mounting device requires a reel holding device that holds the reel. The reel holding device can typically hold a current reel, which is the reel from which the carrier tape is being unwound while being transported by the component supply unit, as well as a refill reel, which is a reel for refilling (see, for example, Patent Document 1 below).

[0003] In the reel holding device described in Patent Document 1, the current reel is installed at a position farther back from the worker's perspective, and the replenishment reel is installed at a position closer to the worker's perspective. The current reel has the wound carrier tape directly supported by the reel holding device, and when the carrier tape is pulled by the component supply unit, it rotates in place to unwind the carrier tape. When the entire carrier tape is unwound, it is no longer supported by the reel holding device and automatically drops and is ejected to the outside. When the used reel is ejected, the component supply unit switches to pulling in the carrier tape from the replenishment reel. The replenishment reel is pulled by the component supply unit and rolls from its standby position to the location of the original current reel, and the wound carrier tape is supported by the reel holding device, automatically replacing the reel.

[0004] [Patent Document 1] International Publication No. 2017 / 061042 Summary of the Invention [Problem to be solved by the invention]

[0005] In a reel holding device, when a new replenishment reel is set to the standby position, a component matching operation is required to confirm that the components on the replenishment reel match the components on the previously set reel. However, in the reel holding device described in Patent Document 1, the reel (current reel) after the component supply unit begins retracting is located further back than the installation position of the replenishment reel. Therefore, in order to perform component matching on the current reel, the worker must remove the current reel, which is located further back, making the component matching operation difficult. This problem tends to become more apparent, particularly in the case of reels with large outer diameters, as it is difficult to remove the reel.

[0011] An embodiment of the present invention will be described with reference to the drawings. Figure 1 shows a component mounting device 1 according to one embodiment of the present invention. The component mounting device 1 is a device for mounting components BH onto a board KB, and includes a mounting device main body 1A, a component supply device 1B, and a reel holding device 1C.

[0012] In FIG. 1, the mounting device main body 1A includes a substrate transport unit 11, a work head 12, and a head moving mechanism 13. The substrate transport unit 11 includes a pair of transport conveyors 11a spaced apart in the left-right direction of FIG. 1 and extending perpendicular to the plane of FIG. 1. The pair of transport conveyors 11a transport the substrate KB and position it at a predetermined work position. From here on, for convenience, the transport direction of the substrate KB by the substrate transport unit 11 will be referred to as the X direction (front-to-back direction), and the up-to-down direction will be referred to as the Z direction. The direction perpendicular to both the X and Z directions will be referred to as the Y direction (front-to-back direction). Furthermore, the right side of the Y direction in FIG. 1 will be referred to as the front (first direction), and the left side in FIG. 1 will be referred to as the rear.

[0013] The work head 12 is equipped with a nozzle 12N that extends downward, and picks up the component BH by supplying vacuum pressure to the nozzle 12N. The head movement mechanism 13 is made up of, for example, an XY table mechanism, and moves the work head 12 in the XY plane.

[0014] The component supply device 1B includes a feeder cart 21 and a component supply unit 22. The feeder cart 21 is equipped with wheels and is movable on the floor surface FL, and includes a block-shaped feeder base 21F on its upper portion that extends in the X direction (see also FIG. 2).

[0015] The component supply unit 22 is composed of a tape feeder and is detachably mounted on the feeder base 21F. The component supply unit 22 transports the carrier tape CT supplied from the reel holding device 1C forward in the Y direction. The carrier tape CT individually contains a plurality of components BH arranged in a line, and the component supply unit 22 transports the carrier tape CT to continuously supply the components BH to the component supply port 22K.

[0016] After positioning the board KB using the board transport unit 11, the mounting device main body 1A moves the work head 12 using the head movement mechanism 13 to repeatedly perform a component transfer operation in which components BH supplied by the component supply device 1B are transferred onto the board KB. The component transfer operation consists of an operation in which the nozzle 12N picks up the components BH supplied by the component supply unit 22, and an operation in which the picked-up components BH are placed at the target placement position on the board KB. By repeating this component transfer operation, a mounted board is manufactured in which components BH are placed on the board KB.

[0017] Next, the reel holding device 1C will be described. The reel holding device 1C is a device that holds a plurality of reels RL around which carrier tape CT is wound, and is used while connected to a feeder cart 21. A component supply unit 22 attached to the feeder cart 21 draws in and transports the carrier tape CT that is unwound forward (in a first direction) from the reel RL held by the reel holding device 1C, and supplies components BH to the loading device main body 1A.

[0018] 1, the reel holding device 1C holds a current reel RLA and a replenishment reel RLB. The current reel RLA is a reel that pays out the carrier tape CT being transported by the component supply unit 22. The replenishment reel RLB is a replenishment reel, that is, a reel that pays out the carrier tape CT to the component supply unit 22 as a new current reel RLA after the current reel RLA runs out of components.

[0019] Thus, in this embodiment, the reel holding device 1C is used in conjunction with a component supply unit 22 that holds a reel RL containing a carrier tape CT and feeds the carrier tape CT unwound from the reel RL forward (in the first direction) while supplying components BH to the work head 12.

[0020] 3, 4, and 5, the reel holding device 1C includes a carriage 31 and a reel holding unit 32. The carriage 31 includes a pair of carriage bases 41 on the left and right. Each carriage base 41 extends in the Y direction (front-to-back direction). Wheels 42 are provided on the underside of the front and rear of each carriage base 41, and the reel holding device 1C can run on the floor surface FL using these four wheels 42. A pair of front support columns 43 on the left and right extends upward from the middle of each of the left and right carriage bases 41, and a pair of rear support columns 44 on the left and right extends upward from the rear end of each of the left and right carriage bases 41.

[0021] 3, 4, and 5, the carriage 31 is provided with a pair of left and right arms 45 extending in the front-to-rear direction. Each arm 45 extends to connect the upper ends of two pairs of left and right front support columns 43 and rear support columns 44 positioned opposite each other in the Y direction.

[0022] 3, 4, and 5, the carriage 31 is provided with a connecting bar 46 extending in the left-right direction. The connecting bar 46 connects the left and right carriage bases 41 at their intermediate portions. A pair of left and right chuck mechanisms 47 extending forward is provided on the connecting bar 46. Each of the left and right chuck mechanisms 47 is provided with a pair of gripping members 47S that grip the connecting pin 21P (see FIG. 10) on the feeder cart 21 side that is inserted into a groove that opens forward. These two gripping members 47S are biased in a direction in which they press against each other (X direction) by a spring member (not shown) built into the chuck mechanism 47.

[0023] 3, 4, and 5, the carriage 31 is provided with a first support bar 48 and a second support bar 49 extending in the X direction. The first support bar 48 connects the front ends of the left and right arms 45, and the second support bar 49 connects the middle parts of the left and right rear supports 44 in the height direction.

[0024] 3 and 5, the carriage 31 is provided with a discharge section 51 into which a used, empty reel RL that has run out of parts is discharged. The discharge section 51 has both ends in the X direction connected to the left and right carriage bases 41 and has a groove-like shape recessed downward.

[0025] 3, 4, and 5, the carriage 31 has left and right alignment sections 55. Each alignment section 55 is attached to the inner surface (facing surface) of the front end of each of the left and right carriage bases 41, and has a shape that protrudes inward (facing each other). The distance between the inner surfaces of the left and right alignment sections 55 is slightly larger than the distance between the outer surfaces of the feeder cart 21.

[0026] 3, 4 and 5, the reel holding unit 32 is configured to include a first reel holding section 61 and a second reel holding section 62 (see also FIG. 6). The first reel holding section 61 has a function of holding the current reel RLA, and the second reel holding section 62 has a function of holding the refill reel RLB.

[0027] 5 and 6, the first reel holding section 61 includes a pair of plate-shaped guide members 71 facing each other in the X direction and two spacer members 72 extending in the X direction. Each of the two spacer members 72 has a cylindrical shape and is provided between the pair of guide members 71. Specifically, the two spacer members 72 are provided in front of the pair of guide members 71, aligned substantially vertically. The spacer members 72 connect the pair of guide members 71, spaced apart in the X direction by a distance slightly greater than the width dimension of the reel RL (the dimension of the reel RL in the X direction). Therefore, the first reel holding section 61 can hold the reel RL within a space surrounded by the two spacer members 72 and the pair of guide members 71. The pair of guide members 71 are parallel to a vertical plane (YZ plane) along the feed direction (Y direction) of the carrier tape CT. Therefore, the first reel holding section 61 can hold the reel RL in an attitude (upright attitude) substantially parallel to the vertical plane. The first reel holding portion 61 also holds the reel RL in a rotatable state. As a result, when the component supply unit 22 pulls in the carrier tape CT that is unwound from the reel RL held in parallel by the first reel holding portion 61, the reel RL rotates while being held by the first reel holding portion 61.

[0028] In this embodiment, the first reel holding section 61 has guide members 71 arranged at a distance that allows the reel RL to be stored therein, and is configured to hold the reel RL between this pair of guide members 71.

[0029] 6, the first reel holding portion 61 has a hook-shaped first engagement portion 73 that opens downward at the upper end of a pair of plate-shaped guide members 71, and a protruding stopper 74 at the rear lower portion of the first reel holding portion 61. A base portion 73a of the first engagement portion 73 and a base portion 74a of the stopper 74 are each attached by being sandwiched between the pair of guide members 71. The first engagement portion 73 engages with the first support bar 48 from above. This allows the first reel holding portion 61 to swing about the first support bar 48 along a vertical plane (YZ plane) that is aligned with the feed direction of the carrier tape CT.

[0030] 5 and 6, the second reel holding section 62 includes a pair of guide plates 81 facing each other in the X direction, multiple reel receiving sections 82 provided between the pair of guide plates 81, and a reel operating section 83 attached to the guide plates 81. The multiple reel receiving sections 82 are made up of cylindrical first and second spacers 82a and 82b extending in the X direction, and a rod-shaped third spacer 82c extending in the Y direction. These three spacers (the first spacer 82a, the second spacer 82b, and the third spacer 82c) connect the pair of guide plates 81 while separating them in the X direction by a distance slightly larger than the width of the reel RL. Therefore, the second reel holding section 62 can hold the reel RL within the space surrounded by the three spacers (the first spacer 82a, the second spacer 82b, and the third spacer 82c) and the pair of guide plates 81.

[0031] The pair of guide plates 81 are parallel to a vertical plane (YZ plane) along the feed direction (Y direction) of the carrier tape CT. Therefore, the second reel holding part 62 can hold the reel RL in a position (upright position) that is approximately parallel to the vertical plane along the feed direction of the carrier tape CT. Furthermore, the second reel holding part 62 holds the reel RL in a rotatable state. As a result, when the component supply unit 22 reels the carrier tape CT unwound from the reel RL held by the second reel holding part 62, the reel RL rotates while being held by the second reel holding part 62.

[0032] In the second reel holding section 62, a reel receiving section 82 consisting of three spacers (a first spacer 82a, a second spacer 82b, and a third spacer 82c) abuts against a reel RL positioned between a pair of guide plates 81, thereby supporting the reel RL within the second reel holding section 62. In the second reel holding section 62, the space surrounded by the pair of guide plates 81 and the reel receiving section 82 consisting of three spacers (the first spacer 82a, the second spacer 82b, and the third spacer 82c) is a replenishment reel mounting space HRS that opens upward and receives a replenishment reel RLB (FIG. 6).

[0033] Thus, in this embodiment, the second reel holding portion 62 includes a pair of guide plates 81 arranged at a distance that allows the reel RL to be stored therein, and a plurality of reel receiving portions 82 that abut against the reel RL between the pair of guide plates 81, and is configured to hold the reel RL in the space surrounded by the pair of guide plates 81 and the plurality of reel receiving portions 82.

[0034] 6 and 7, the reel operation unit 83 has a rear end (closer to the operator) fixed to the lower part of the guide plate 81, and a front end (closer to the component supply device 1B) protruding forward of the guide plate 81 and extending into the space sandwiched between the pair of guide members 71. The portion of the reel operation unit 83 that protrudes forward of the guide plate 81 (hereinafter referred to as the "protruding portion 83T") has its middle portion pivotally connected (coupled so as to be swingable) to the guide member 71 of the first reel holding unit 61 by a connecting portion 84 that extends in the X-axis direction. Therefore, the second reel holding unit 62 can swing along a vertical plane (YZ plane) along the feed direction of the carrier tape CT, and therefore the reel operation unit 83 can also swing within that vertical plane (YZ plane). The tip 83S of the protrusion 83T extends in a direction away from the second reel holding portion 62 beyond the connecting portion 84 and enters the space sandwiched between the pair of guide members 71, in an area above the stopper 74.

[0035] In this embodiment, the first reel holding portion 61 and the second reel holding portion 62 are directly connected so as to be freely swingable, and the first reel holding portion 61 and the second reel holding portion 62 form a link mechanism.

[0036] 6 and 7, a hook-shaped second engagement portion 85 that opens downward is formed on the rear lower portion of the pair of guide plates 81. The second engagement portion 85 can be engaged with the second support bar 49 from above (FIG. 7).

[0037] Returning to Figure 5, the reel holding unit 32 has supported portions (first engagement portions 73 and second engagement portions 85) that are supported by the reel holding unit support portions (first support bar 48 and second support bar 49). The reel holding unit 32 is supported by engaging the supported portions (first engagement portions 73 and second engagement portions 85) with the reel holding unit support portions (first support bar 48 and second support bar 49) from above. Specifically, the reel holding unit support portions (first support bar 48 and second support bar 49) support the reel holding unit 32 by engaging the first engagement portions 73 with the first support bar 48 and the second engagement portions 85 with the second support bar 49 from above.

[0038] The first support bar 48 and the second support bar 49 are rod-shaped members with no irregularities on their outer peripheries, and the supported portions (first engagement portion 73 and second engagement portion 85) are slidable along the first support bar 48 and the second support bar 49. Therefore, the reel holding unit 32 supported by the first support bar 48 and the second support bar 49 can move along the first support bar 48 and the second support bar 49 while being supported by the reel holding unit support portions (first support bar 48 and second support bar 49). In other words, the reel holding unit support portions (first support bar 48 and second support bar 49) can support the multiple reel holding units 32 in a state where they can slide freely in the arrangement direction (the direction of arrow W shown in FIG. 4). This allows the operator to change the position of the reel holding unit 32 in the arrangement direction (X direction) without removing it from the reel holding unit support portions (first support bar 48 and second support bar 49).

[0039] As described above, the reel holding device 1C in this embodiment includes a reel holding unit 32 that holds a reel RL, and a reel holding unit support portion (first support bar 48 and second support bar 49) that supports a plurality of reel holding units 32 arranged in the parallel direction in which a plurality of component supply units 22 are arranged in parallel. The reel holding unit support portion is made up of two support bars (the first support bar 48 and the second support bar 49) that extend in the parallel direction of the reel holding units 32, and the reel holding unit 32 is configured to be slidable in the parallel direction of the component supply units 22 by engaging the first engagement portion 73 and the second engagement portion 85, which serve as supported portions, with the first support bar 48 and the second support bar 49 from above.

[0040] In the past, the mounting positions of the reel holding unit 32 on the reel holding unit support section (first support bar 48 and second support bar 49) were limited to a plurality of mounting slots partitioned in the X direction, and changing the mounting position required removing the reel holding unit 32 from the existing mounting slot and remounting it in a different mounting slot. In contrast, the reel holding unit support section (first support bar 48 and second support bar 49) of this embodiment does not have the concept of a slot, so the reel holding unit 32 can be mounted in a convenient position, and since it is supported in a slidable state, even after mounting, it can be easily repositioned or temporarily moved for inspection or confirmation. Therefore, a reel holding device 1C that is easier to operate than conventional devices can be provided.

[0041] In Figure 7, the reel holding unit 32 supported by the reel holding unit support parts (first support bar 48 and second support bar 49) is bent around the connecting part 84 due to its own weight, and is in a position where the tip part 83S of the reel operating part 83 faces downward. The position of the reel holding unit 32 in this manner (the position shown in Figure 7) where the second engaging part 85 of the second reel holding part 62 engages with the second support bar 49 and the reel operating part 83 faces downward will be referred to below as the "first position." Furthermore, the position of the second reel holding part 62 in which the tip part 83S of the reel operating part 83 faces downward (Figure 7) will be referred to below as the "downward position."

[0042] When the operator grasps the rear end of the second reel holding part 62 and pulls it up diagonally rearward (arrow P1 in FIG. 8) while the reel holding unit 32 is in the first position (FIG. 7), the second engagement part 85 of the second reel holding part 62 disengages from the second support bar 49, and the first reel holding part 61 is pulled up rearward by the second reel holding part 62 via the connecting part 84. Then, when the stopper 74 of the first reel holding part 61 abuts against the second support bar 49 from below, the second reel holding part 62 can no longer be pulled up (FIG. 8).

[0043] The position of the reel holding unit 32 in which the second reel holding portion 62 is pulled upward and rearward in this manner and the stopper 74 of the first reel holding portion 61 abuts against the second support bar 49 (FIG. 8) will be referred to hereinafter as the "second position." Note that when the second reel holding portion 62 is positioned in this second position, the second reel holding portion 62 maintains a downward orientation with the tip portion 83S of the reel operating portion 83 facing downward.

[0044] When the operator lowers the rear end of the second reel holding part 62 downward (arrow P2 shown in FIG. 9) from a state in which the reel holding unit 32 is located in the "second position" (FIG. 8), the reel operation part 83 abuts against the second support bar 49 from above, and then the reel operation part 83 swings in the rearward downward direction around the connecting part 84 while maintaining a state of abutting against the second support bar 49. Then, when the second support bar 49 is sandwiched between the stopper 74 and the reel operation part 83, the operator cannot lower the second reel holding part 62 any further (FIG. 9).

[0045] The position of the reel holding unit 32 when the second reel holding portion 62 cannot be lowered any further (FIG. 9) will be referred to below as the "third position." Furthermore, when the reel holding unit 32 is in this third position, the second reel holding portion 62 is in a position where the tip portion 83S of the reel operation portion 83 faces upward. The position of the second reel holding portion 62 when the reel holding unit 32 is in the third position and the tip portion 83S of the reel operation portion 83 faces upward (FIG. 9) will be referred to below as the "upward position."

[0046] 2, feeder cart 21 of component supply device 1B has a receiving space 21S in its center that is open to the rear. Feeder cart 21 also has horizontal beams 21B at its rear that extend in the X direction, and the pair of left and right connecting pins 21P that protrude downward are provided on the underside of horizontal beams 21B.

[0047] When connecting the reel holding device 1C to the feeder cart 21 of the component supply device 1B, the operator first positions the reel holding device 1C behind the feeder cart 21, as shown in Fig. 10. At this time, the reel holding unit 32 is positioned at the first position.

[0048] After positioning the reel holding device 1C behind the feeder cart 21, the worker moves the reel holding device 1C closer to the feeder cart 21 (Fig. 11(a) → Fig. 11(b)). As a result, the leading portions of the reel holding device 1C (leading portions of the left and right carriage bases 41) move toward the inside of the feeder cart 21 with the inner surfaces of the left and right alignment portions 55 being guided by the outer surfaces of the feeder cart 21.

[0049] As the reel holding device 1C advances toward the inside of the feeder cart 21, the leading end of the reel holding device 1C is positioned in the lateral direction (X direction) relative to the feeder cart 21 by the left and right alignment units 55. Then, as the reel holding device 1C advances further, the connecting bar 46 of the carriage 31 abuts against a predetermined position on the feeder cart 21 from behind, and the device is positioned in the front-to-rear direction (Y direction).

[0050] When the carriage 31 is positioned in the Y direction relative to the feeder cart 21, the left and right connecting pins 21P provided on the feeder cart 21 are wedged between the left and right gripping members 47S of the left and right chuck mechanisms 47 provided on the reel holding device 1C. As a result, the left and right connecting pins 21P are chucked by the left and right chuck mechanisms 47 (FIG. 12), and the reel holding device 1C is connected to the feeder cart 21 (FIG. 11(b)). Note that when the carriage 31 is pulled rearward away from the feeder cart 21 with the connecting pins 21P chucked by the chuck mechanisms 47 in this manner, the left and right gripping members 47S are pushed open by the connecting pins 21P, the chucks are released, and the carriage 31 can be separated from the feeder cart 21.

[0051] 2, when the reel holding device 1C is connected to the feeder cart 21, the front part of the first reel holding portion 61 of the reel holding unit 32 provided in the reel holding device 1C is located within the receiving space 21S of the feeder cart 21. In addition, the rear part of the first reel holding portion 61 is located behind the feeder cart 21.

[0052] Once the reel holding device 1C is connected to the feeder cart 21 as described above, the operator causes the reel holding unit 32 to hold the reel RL. To do this, first, the operator lifts the second reel holding portion 62 of the reel holding unit 32, which is positioned in the first position, upward and rearward (FIG. 7 → FIG. 8), thereby positioning the reel holding unit 32 in the second position (FIG. 8). Then, once the reel holding unit 32 is positioned in the second position, the operator lowers the rear end of the second reel holding portion 62 (FIG. 8 → FIG. 9), thereby positioning the reel holding unit 32 in the third position (FIGS. 9 and 13).

[0053] 13, when the reel holding unit 32 is in the third position, the second reel holding portion 62 is in an upward position with the tip portion 83S of the reel operation portion 83 facing upward. When the second reel holding portion 62 is in this upward position, a work space SGS on which the reel RL can be placed appears in the area on the second reel holding portion 62 between the reel operation portion 83 (more specifically, the protrusion 83T) and a part of the reel receiving portion 82 (the first spacer 82a) (FIG. 13).

[0054] When the reel holding unit 32 is positioned in the third position (the second reel holding portion 62 is placed in an upward position) and a workspace SGS appears on the reel holding unit 32, the worker places the reel RL that will become the current reel RLA in the workspace SGS, and places the reel RL that will become the replenishment reel RLB in the replenishment reel placement space HRS (Figure 13).

[0055] After placing the reel RL in the work space SGS, the worker pulls out the carrier tape CT from the reel RL and inserts the leading end of the pulled-out carrier tape CT into the tape insertion opening 22G at the rear of the component supply unit 22 mounted on the feeder base 21F of the feeder cart 21 (FIG. 14).

[0056] In this embodiment, the work space SGS that appears when the reel holding unit 32 is positioned in the third position is a work space where the worker can place the reel RL, pull out the carrier tape CT from the placed reel RL, and insert it into the component supply unit 22.

[0057] When the leading end of the carrier tape CT pulled out from the reel RL placed in the work space SGS is inserted into the tape insertion port 22G of the component supply unit 22, the component supply unit 22 starts pulling in the carrier tape CT. As a result, the reel RL on the work space SGS is pulled forward (towards the component supply unit 22) through the carrier tape CT, and thereafter the reel RL becomes the current reel RLA.

[0058] The reel RL on the workspace SGS, which has become the current reel RLA, rotates as the carrier tape CT is pulled forward by the component supply unit 22, but because the tip 83S of the reel operation part 83 faces upward, the current reel RLA rotates (rotates in place) on the reel operation part 83, i.e., on the workspace SGS. In other words, the second reel holding part 62 maintains the state in which it holds the reel RL on the workspace SGS even after the component supply unit 22 starts to pull in the carrier tape CT of the reel RL on the workspace SGS.

[0059] The worker inserts the leading end of the carrier tape CT pulled out from the reel RL (current reel RLA) placed in the work space SGS into the component supply unit 22, and then lifts up the second reel holding part 62 (Fig. 14 → Fig. 15). This causes the reel holding unit 32 to swing around the connecting part 84 and take up the second position (Fig. 15).

[0060] When the reel holding unit 32 is in the second position, the second reel holding part 62 is in a downward position with the tip 83S of the reel operation part 83 facing downward. When the second reel holding part 62 changes from an upward position to a downward position, the current reel RLA placed in the workspace SGS moves forward and downward under its own weight while being guided by the reel operation part 83, and is housed between the pair of guide members 71 that make up the first reel holding part 61 (FIG. 15).

[0061] 15, the front portion of the outer periphery of the current reel RLA housed in the first reel holding portion 61 abuts against one of the lower two spacer members 72 (the spacer member designated by the symbol "72a" in FIG. 15) provided in the first reel holding portion 61 (constituting the first reel holding portion 61), and also against the tip portion 83S of the reel operating portion 83. As a result, the current reel RLA is supported by the spacer member 72 and the reel operating portion 83 between the pair of guide members 71 of the first reel holding portion 61 (FIG. 15).

[0062] Thus, in this embodiment, the spacer member 72 serves as an abutment portion that abuts against the portion of the outer periphery of the reel RL held by the first reel holding portion 61 that is forward (i.e., toward the first direction) when viewed from the center axis of the reel RL.

[0063] Furthermore, in this embodiment, the second reel holding section 62 can be changed between an upward position (first position) in which the tip 83S of the reel operation section 83 faces upward relative to the first reel holding section 61, and a downward position (second position) in which the tip 83S of the reel operation section 83 faces downward. When the second reel holding section 62 is in the upward position, it creates a work space SGS in which a reel RL can be placed and which can maintain the state in which the reel RL is held even after the component supply unit 22 begins to pull in the carrier tape CT. When the second reel holding section 62 is in the downward position, the reel RL placed in the work space SGS is guided by the reel operation section 83 and sent to the first reel holding section 61.

[0064] Therefore, the worker can move the reel RL on the workspace SGS to the first reel holding part 61 at any timing by selecting the timing for changing the second reel holding part 62 from the upward position to the downward position. In other words, the worker can send the reel RL on the workspace SGS to the first reel holding part 61 at his / her own will and by his / her own operation. Therefore, there is no chance that the current reel RLA will be moved to the first reel holding part 61 that is out of the worker's reach without the worker realizing it.

[0065] The refill reel RLB held in the refill reel mounting space HRS of the second reel holding portion 62 remains held in the refill reel mounting space HRS even when the reel operating portion 83 changes from an upward position to a downward position. In detail, when the second reel holding portion 62 changes from an upward position to a downward position, the refill reel RLB in the refill reel mounting space HRS moves forward and downward along the third spacer 82c, but comes to a stop when it abuts against the first spacer 82a and remains in that state (FIG. 15).

[0066] After the worker has fed the reel RL (current reel RLA) on the workspace SGS into the first reel holding part 61 as described above, he or she moves the second reel holding part 62 forward and downward so as to approach the first reel holding part 61 (arrow P3 shown in FIG. 16). Then, the worker engages the second engagement part 85 provided on the second reel holding part 62 with the second support bar 49 of the dolly 31, thereby positioning the reel holding unit 32 at the first position (FIG. 16). Due to the movement of the second reel holding part 62 (reel operation part 83) during this time, the first reel holding part 61 swings around the first support bar 48 in a direction raising the front end side, and a part of the current reel RLA, including its front half, is positioned within the receiving space 21S of the feeder cart 21 (FIG. 16).

[0067] When the reel holding unit 32 is located in the first position, the front end of the current reel RLA is supported by an abutment portion made of a spacer member 72 provided on the first reel holding portion 61, and the rear end is supported by the rear end of the concave bottom surface 21M of the feeder cart 21 that forms the receiving space 21S (FIG. 16). In this state, the center of gravity GV of the current reel RLA is located between the abutment portion (spacer member 72) and the rear end of the bottom surface 21M. Therefore, even if the carrier tape CT of the current reel RLA is pulled out by the component supply unit 22 and a rotational force is applied to the current reel RLA by the tension of the carrier tape CT, the current reel RLA rotates stably on the spot.

[0068] Even when the reel holding unit 32 is displaced from the second position to the first position as described above, the replenishment reel RLB in the replenishment reel mounting space HRS remains positioned within the replenishment reel mounting space HRS (FIG. 16). Once the reel holding unit 32 is positioned at the first position, the operator pulls out the carrier tape CT from the replenishment reel RLB and inserts the leading end of the carrier tape CT into the tape insertion port 22G of the component supply unit 22 (FIG. 16).

[0069] The component supply device 1B draws in and transports the carrier tape CT from the current reel RLA held by the first reel holding part 61 located in the first position, and supplies the components BH (FIG. 16). As the component supply unit 22 continues to supply the components BH, if the current reel RLA runs out of components, i.e., the carrier tape CT on the current reel RLA runs out, the current reel RLA becomes a used reel RL, and the component supply unit 22 switches the target to draw in to the carrier tape CT being unwound from the replenishment reel RLB placed in the replenishment reel placement space HRS, and continues supplying the components BH (FIG. 17).

[0070] When the component supply unit 22 begins to pull in the carrier tape CT from the refill reel RLB placed in the refill reel placing space HRS, the previous refill reel RLB is switched to the current reel RLA. This reel RL, which has now become the current reel RLA, rotates (rotates in place) within the refill reel placing space HRS. In other words, the second reel holding section 62 maintains its hold on the reel RL in the refill reel placing space HRS even after the component supply unit 22 begins to pull in the carrier tape CT from the reel RL in the refill reel placing space HRS.

[0071] After the worker confirms that the component supply unit 22 has started to retract the carrier tape CT of the current reel RLA on the replenishment reel mounting space HRS, the worker performs the work of ejecting the used reel RL from the first reel holding part 61. To do this, the worker first pulls the second reel holding part 62 upward and rearward (arrow P1 shown in FIG. 18) to displace the reel holding unit 32 to the second position (FIG. 18).

[0072] When the reel holding unit 32 is displaced to the second position, the reel operation part 83 moves rearward and upward together with the second reel holding part 62, and the first reel holding part 61 is also pulled up toward the rear end via the connecting part 84 (FIG. 18). This causes the first reel holding part 61 to swing around the first support bar 48 in a direction lowering its front end, and the used reel RL is moved to the rear of the receiving space 21S of the feeder cart 21, i.e., to the reel discharge position, by the spacer member 72 acting as an abutment (FIG. 18). When the reel holding unit 32 is displaced to the second position, the linear distance connecting the spacer member 72 and the tip end 83S of the reel operation part 83 is smaller than the outer diameter of the reel RL, and therefore the used reel RL that has moved to the discharge position remains at the discharge position without falling.

[0073] Once the used reel RL has moved to the discharge position, the operator moves the rear side of the second reel holding part 62 downward (arrow P2 shown in FIG. 19). This causes the second reel holding part 62 to swing in the YZ plane around the second support bar 49, displacing the reel holding unit 32 to the third position, and the second reel holding part 62 assumes an upward orientation (FIG. 19).

[0074] When the second reel holding portion 62 is in the upward position, the linear distance connecting the tip end 83S of the reel operating portion 83 and the spacer member 72 becomes larger than the outer diameter of the reel RL, so the used reel RL falls downward from the discharge position due to its own weight and is discharged to the discharge portion 51 (FIG. 19). As described above, the spacer member 72 as the abutting portion presses the used reel RL rearward to move it to the discharge position, and this "rearward" means the opposite direction to the forward direction (first direction), which is the feed direction of the carrier tape CT.

[0075] As described above, in the reel holding device 1C of this embodiment, the used reel RL is not automatically discharged, but is discharged by the operator's operation at the operator's discretion.

[0076] As can be seen from the above explanation, when the second reel holding portion 62 is in a downward position (second position), the position of the reel operation portion 83 is a position (first position, Figure 18) that prevents the reel RL held in the first reel holding portion 61 from being ejected from the first reel holding portion 61, and when the second reel holding portion 62 is in an upward position (first position), the position of the reel operation portion 83 is a position (second position, Figure 19) that allows the reel RL held in the first reel holding portion 61 to be ejected from the first reel holding portion 61.

[0077] That is, in the reel holding device 1C of this embodiment, when the reel holding unit 32 is displaced from the second position to the third position and the second reel holding portion 62 changes from a downward posture to an upward posture, the reel operating portion 83 provided on the second reel holding portion 62 is displaced from a position (first position) that prevents the current reel RLA held by the first reel holding portion 61 from being discharged to the discharge portion 51 to a position (second position) that allows the current reel RLA moved by the spacer member 72, which is the abutment portion, to be discharged to the discharge portion 51 (Figure 18 → Figure 19).

[0078] In this embodiment, the second reel holding portion 62 functions as an operating means that moves the spacer member 72, which serves as the abutment portion, rearward to eject the current reel RLA from the first reel holding portion 61. In other words, when the second reel holding portion 62, which serves as the operating means, swings relative to the first reel holding portion 61, the reel operating portion 83 provided on the second reel holding portion 62 is displaced between a first position that prevents the reel RL held by the first reel holding portion 61 from being ejected from the first reel holding portion 61, and a second position that allows the reel RL, which has been moved by the spacer member 72, which serves as the abutment portion, to be ejected from the first reel holding portion 61.

[0079] When the reel holding unit 32 is displaced from the second position to the third position and the used reel RL is discharged to the discharge section 51, the worker removes the reel RL that has become the new current reel RLA from the replenishment reel placement space HRS (arrow L shown in FIG. 19) and places it in the newly appeared work space SGS (FIG. 20). Then, the worker places the new replenishment reel RLB in the newly vacant replenishment reel placement space HRS (FIG. 21). This results in the same state as in FIG. 14 described above, so by repeatedly performing the same operations, the component supply unit 22 can continue to supply components.

[0080] As described above, the reel holding device 1C in this embodiment comprises a carriage 31, a first reel holding section 61 that is freely swingable relative to the carriage 31 and holds the current reel RLA, and a second reel holding section 62 that is directly swingably connected to the first reel holding section 61 and holds the replenishment reel RLB. When the second reel holding section 62 is operated, the first reel holding section 61 swings relative to the carriage 31 in response, thereby ejecting a used reel RL from the first reel holding section 61, or sending the replenishment reel RLB placed on the second reel holding section 62 to the first reel holding section 61 as a new current reel RLA.

[0081] Therefore, with the reel holding device 1C of this embodiment, the reel RL (current reel RLA) can be easily retrieved at any time even after it has been set in the first reel holding part 61, improving workability when it becomes necessary to retrieve the reel RL in use, such as during a setup change. Also, the first reel holding part 61 and the second reel holding part 62 form a single reel holding unit 32, and this reel holding unit 32 is configured to be attached to the cart 31, which simplifies the configuration of the reel holding device 1C and makes maintenance easier.

[0082] Furthermore, in this embodiment, a work space SGS is formed that holds the reel RL before it is fed into the first reel holding section 61 and allows the reel RL to rotate on the spot. Therefore, after the worker performs the component matching work in the work space SGS, the worker can feed the reel RL into the first reel holding section 61 at any timing.

[0083] As described above, the reel holding device 1C in this embodiment includes a first reel holding unit 61 that holds the current reel RLA and a second reel holding unit 62 that holds the replenishment reel RLB. The second reel holding unit 62 is capable of shifting between an upward position, in which the tip 83S of the reel operation unit 83 faces upward, and a downward position, in which the tip 83S of the reel operation unit 83 faces downward, relative to the first reel holding unit 61. When in the upward position, the second reel holding unit 62 creates a workspace SGS in which a reel RL can be placed and which can maintain a state in which the reel RL is held even after the component supply unit 22 begins to retract the carrier tape CT. When in the downward position, the reel RL placed in the workspace SGS can be sent to the first reel holding unit 61. This allows the reel RL in the workspace SGS to be sent to the first reel holding unit 61 at any time, facilitating component matching operations for the current reel RLA. When it is necessary to remove the reel RL for component verification, the larger the outer diameter of the reel RL, the heavier it will be, and therefore the effect of this embodiment becomes greater the larger the diameter of the reel.

[0084] While the present invention has been described above with reference to exemplary embodiments, it is not limited to the above and various modifications are possible. For example, in the above-described exemplary embodiments, the abutment portion that abuts against the outer periphery of the current reel RLA held by the first reel holding portion 61 to move the current reel RLA is provided on the first reel holding portion 61. However, the abutment portion does not necessarily have to be provided on the first reel holding portion 61 and may be provided on a mechanism that swings about the X-axis independently of the first reel holding portion 61. In the above-described exemplary embodiments, the abutment portion that presses the used reel RL rearward is a component of the first reel holding portion 61, and therefore the abutment portion is moved rearward by swinging the first reel holding portion 61 about the first support bar 48. However, this is not the case when the abutment portion is not provided on the first reel holding portion 61.

[0085] Furthermore, in the above-described embodiment, the second reel holding portion 62 can be changed between the first position and the second position, but the second reel holding portion 62 may be changed to a position other than the first position and the second position. In other words, it is sufficient that the second reel holding portion 62 can be displaced at least between the first position and the second position.

[0086] Furthermore, in the above-described embodiment, the second reel holding portion 62 is configured to be directly connected to the first reel holding portion 61 so as to be freely swingable, but the second reel holding portion 62 may also be configured to be indirectly connected to the first reel holding portion 61 so as to be freely swingable.

[0087] In the above-described embodiment, the reel holding unit support portion that holds the plurality of reel holding units 32 in a direction in which the plurality of component supply units 22 are arranged side by side (parallel direction) is made up of two support bars (two support bars, the first support bar 48 and the second support bar 49), but the support bar may include at least one support bar that extends in the parallel direction of the plurality of component supply units 22. The supported portion (the first engagement portion 73 and the second engagement portion 85 in the above-described embodiment) of the reel holding unit 32 may be engaged with the support bar from above.
