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, there is known a component mounting device that manufactures a mounted board 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. Since a tape feeder draws in and transports the carrier tape that is unwound from a reel, the component mounting device requires a reel holding device that holds the reel. The reel holding device can usually hold a refill reel that is a refill reel in addition to a current reel that is a reel that unwinds the carrier tape being transported by the component supply unit (for example, see Patent Document 1 below).

[0003] In the reel holding device described in the above Patent Document 1, the current reel is installed at a position on the far side as viewed from the worker, and the refill reel is installed at the near side as viewed from the worker. 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 on the spot to pay out the carrier tape. When all the carrier tape is pulled out, the part supported by the reel holding device is no longer present, and the reel automatically falls and is discharged to the outside. When the used reel is discharged, the component supply unit switches the target for pulling the carrier tape to the carrier tape of the refill reel. The refill reel is pulled by the component supply unit and rolls from the standby position, moving to the location where the original current reel was located, and the wound carrier tape is supported by the reel holding device, so that the reel is automatically replaced.

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

[0005] However, in a configuration in which the reel is supported via the carrier tape, as in the reel holding device described in the above patent document, the entire weight of the reel acts on the carrier tape, so there is a risk that a great deal of friction acts on the surface of the carrier tape pulled out from the reel, causing parts to break, or that parts may be damaged by static electricity generated by friction. In addition, there is a risk that the feed motor of the part supply unit that pulls in the carrier tape may break down due to an excessive load, or that its useful life may be shortened. In particular, the problem tends to become more apparent in reels with large outer diameters, since they are heavy. In addition, when a new reel is set to the standby position, it is necessary to perform a parts matching operation to confirm that the parts on the reel match the parts on the discharged used reel. However, in the reel holding device described in the patent document, the used reel automatically falls, so that the worker may not notice the discharge of the used reel. For this reason, there is a problem that if a worker tries to perform parts matching and there are other empty reels of different types mixed in the reel discharge section, the worker may lose sight of the reel to be matched, and accurate parts matching may not be performed.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a reel holding device and a component mounting device which prevent damage to the carrier tape wound around the reel and are also suitable for component verification operations. [Means for solving the problem]

[0007] The reel holding device of the present invention is a reel holding device used in conjunction with a component supply unit that holds a reel containing a carrier tape in which components are enclosed, and supplies components to a work head while feeding the carrier tape unwound from the reel in a first direction, and is equipped with a first reel holding portion that holds the reel, a contact portion that abuts against the portion of the outer periphery of the reel held in the first reel holding portion that is on the first direction side when viewed from the central axis of the reel, and an operating means that moves the abutment portion in a direction opposite to the first direction to eject the reel held in the first reel holding portion from the first reel holding portion.

[0008] The component mounting device of the present invention is a component mounting device comprising a reel holding device which holds a reel containing a carrier tape in which components are enclosed, a work head which removes components from the carrier tape and mounts them on a substrate, and a component supply unit which supplies components to the work head while feeding the carrier tape unwound from the reel in a first direction, wherein the reel holding device comprises a first reel holding portion which holds a reel, a contact portion which abuts against a portion of the outer periphery of the reel held in the first reel holding portion that is on the first direction side when viewed from the central axis of the reel, and an operating means which moves the contact portion in a direction opposite to the first direction to eject the reel held in the first reel holding portion from the first reel holding portion.

[0011] An embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a component mounting device 1 in one embodiment of the present invention. The component mounting device 1 is a device that mounts components BH on 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 board transport section 11, a work head 12, and a head moving mechanism 13. The board transport section 11 includes a pair of transport conveyors 11a that are spaced apart in the left-right direction of Fig. 1 and extend in a direction perpendicular to the paper surface of Fig. 1, and the pair of transport conveyors 11a transport the board KB and position it at a predetermined work position. From here on, for convenience, the transport direction of the board KB by the board transport section 11 is referred to as the X direction (front-rear direction), and the up-down direction is referred to as the Z direction. In addition, the direction perpendicular to both the X direction and the Z direction is referred to as the Y direction (front-rear direction). Furthermore, in the Y direction, the right side in Fig. 1 is referred to as the front (first direction), and the left side in Fig. 1 is referred to as the rear.

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

[0014] The component supplying device 1B includes a feeder cart 21 and a component supplying unit 22. The feeder cart 21 is equipped with wheels and can move freely on a floor surface FL, and includes a block-shaped feeder base 21F extending in the X direction on its upper portion (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. A plurality of components BH are individually enclosed in the carrier tape CT 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 working head 12 using the head moving mechanism 13 to repeatedly perform a component transfer operation to transfer the components BH supplied by the component supply device 1B to the board KB. The component transfer operation consists of an operation of picking up the components BH supplied by the component supply unit 22 using the nozzle 12N, and an operation of mounting the picked-up components BH at the target mounting position on the board KB. By repeating this component transfer operation, a mounted board is manufactured in which the components BH are mounted 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 a carrier tape CT is wound, and is used in a state where it is connected to a feeder cart 21. The component supply unit 22 mounted on 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 mounting 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 reel for replenishing, 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 storing a carrier tape CT and supplies components BH to the work head 12 while feeding the carrier tape CT unwound from the reel RL forward (in a first direction).

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

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

[0022] 3, 4, and 5, the cart 31 is provided with a connecting bar 46 extending in the left-right direction. The connecting bar 46 connects the left and right cart bases 41 at the middle between the left and right cart bases 41. A pair of left and right chuck mechanisms 47 protruding 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 cart 31 is equipped 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 to each other, and the second support bar 49 connects the middle parts of the left and right rear supports 44 in the height direction to each other.

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

[0025] 3, 4, and 5, the cart 31 has left and right alignment parts 55. Each alignment part 55 is attached to the inner surface (facing surface) of the front end of each of the left and right cart bases 41, and has a shape that protrudes inward (facing side). The distance between the inner surfaces of the left and right alignment parts 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 a current reel RLA, and the second reel holding section 62 has a function of holding a 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. In detail, the two spacer members 72 are provided in front of the pair of guide members 71, side by side in the vertical direction. The spacer members 72 connect the pair of guide members 71 at a distance in the X direction that is slightly larger 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 in 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 a posture (upright posture) that is substantially parallel to the vertical plane. Furthermore, the first reel holding portion 61 holds the reel RL in a rotatable state. As a result, when the component supply unit 22 draws 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] As described above, in this embodiment, the first reel holding portion 61 has guide members 71 arranged at a distance capable of storing the reel RL, and is configured to hold the reel RL between this pair of guide members 71.

[0029] 6, the first reel holding part 61 has a hook-shaped first engagement part 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 part of the first reel holding part 61. A base part 73a of the first engagement part 73 and a base part 74a of the stopper 74 are each attached by being sandwiched between the pair of guide members 71. The first engagement part 73 engages with the first support bar 48 from above. Therefore, the first reel holding part 61 can swing around the first support bar 48 along a vertical plane (YZ plane) along 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, a plurality of 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 plurality of reel receiving sections 82 are made up of a cylindrical first spacer 82a and a second spacer 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 at a distance in the X direction that is slightly larger than the width dimension of the reel RL. Therefore, the second reel holding section 62 can hold the reel RL within a 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. In addition, the second reel holding part 62 holds the reel RL in a rotatable state. As a result, when the component supply unit 22 reels in 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 portion 62, a reel receiving portion 82 consisting of three spacers (a first spacer 82a, a second spacer 82b, and a third spacer 82c) abuts against the reel RL positioned between a pair of guide plates 81, thereby supporting the reel RL within the second reel holding portion 62. In the second reel holding portion 62, the space surrounded by the pair of guide plates 81 and the reel receiving portion 82 consisting of three spacers (the first spacer 82a, the second spacer 82b, and the third spacer 82c) is a reel mounting space HRS that opens upward and receives a 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 sufficient to store the reel RL, 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 multiple reel receiving portions 82.

[0034] 6 and 7, the rear end side (the side facing the operator) of the reel operation unit 83 is fixed to the lower part of the guide plate 81, and the front end side (the side facing the component supply device 1B) protrudes forward of the guide plate 81 and extends into the space sandwiched between the pair of guide members 71. The portion of the reel operation unit 83 protruding 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 freely swingable) to the guide member 71 of the first reel holding unit 61 by a connecting portion 84 extending 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). A tip portion 83S of the protrusion 83T extending in a direction away from the second reel holding portion 62 beyond the connecting portion 84 enters an area above the stopper 74 in the space sandwiched between the pair of guide members 71.

[0035] In this manner, in this embodiment, the first reel holding portion 61 and the second reel holding portion 62 are directly connected to each other 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 FIG. 5, the reel holding unit 32 includes a supported portion (first engagement portion 73 and second engagement portion 85) supported by the reel holding unit supporting portion (first support bar 48 and second support bar 49). The reel holding unit 32 is supported by engaging the supported portion (first engagement portion 73 and second engagement portion 85) with the reel holding unit supporting portion (first support bar 48 and second support bar 49) from above. Specifically, the reel holding unit supporting portion (first support bar 48 and second support bar 49) supports the reel holding unit 32 by engaging the first engagement portion 73 with the first support bar 48 and the second engagement portion 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 having no irregularities on the outer circumference, and the supported parts (the first engagement part 73 and the second engagement part 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 part (the first support bar 48 and the second support bar 49). In other words, the reel holding unit support part (the first support bar 48 and the second support bar 49) can support the multiple reel holding units 32 in a state in which they can slide freely in the arrangement direction (the direction of the 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 part (the first support bar 48 and the 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 holds a plurality of reel holding units 32 arranged in a 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, from above with the first support bar 48 and the second support bar 49.

[0040] Conventionally, the mounting position of the reel holding unit 32 in the reel holding unit support section (first support bar 48 and second support bar 49) was limited to a plurality of mounting slots partitioned in the X direction, and when changing the mounting position, it was necessary to remove the reel holding unit 32 from the existing mounting slot and remount it in another 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 is easy to perform operations such as changing the position or temporarily shifting the position for inspection and confirmation. Therefore, it is possible to provide a reel holding device 1C that is easier to operate than conventional devices.

[0041] In Fig. 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 about the connecting part 84 due to its own weight, and is in a position in which the tip part 83S of the reel operation part 83 faces downward. The position of the reel holding unit 32 in this manner, in which the second engagement part 85 of the second reel holding part 62 engages with the second support bar 49 and the reel operation part 83 faces downward (the position shown in Fig. 7), will be referred to below as the "first position". Also, the position of the second reel holding part 62 in which the tip part 83S of the reel operation part 83 faces downward (Fig. 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 and upward (arrow P1 shown in FIG. 8) from a state in which the reel holding unit 32 is located in the first position (FIG. 7), the second engagement part 85 of the second reel holding part 62 comes off the second support bar 49, and the first reel holding part 61 is pulled up rearward and upward by the second reel holding part 62 via the connection 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 cannot be pulled up any further (FIG. 8).

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

[0044] When the operator lowers the rear end of second reel holding part 62 downward (arrow P2 shown in FIG. 9) from a state in which reel holding unit 32 is located in the "second position" (FIG. 8), reel operation part 83 abuts against second support bar 49 from above, and then reel operation part 83 swings in the rearward downward direction about connecting part 84 while maintaining abutment against second support bar 49. Then, when stopper 74 and reel operation part 83 assume a position in which second support bar 49 is sandwiched between them, the operator is unable to lower 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) is hereinafter referred to as the "third position." Also, when the reel holding unit 32 is in the third position, the second reel holding portion 62 is in a position in which the tip portion 83S of the reel operation portion 83 faces upward. The position of the second reel holding portion 62 in which 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) is hereinafter referred to as the "upward position."

[0046] 2, the feeder cart 21 of the component supplying device 1B has a receiving space 21S in its center that is open to the rear. The feeder cart 21 also has a horizontal bar portion 21B extending in the X direction at its rear, and the pair of left and right connecting pins 21P protruding downward are provided on the lower surface of the horizontal bar portion 21B.

[0047] When connecting the reel holding device 1C to the feeder cart 21 of the component supplying device 1B, the worker 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 in 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 portion of the reel holding device 1C (leading portions of the left and right cart bases 41) advances 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 of the feeder cart 21 from behind, and the device is positioned in the front-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 inserted 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)). When the carriage 31 is pulled backward away from the feeder cart 21 from the state in which the connecting pins 21P are 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 part 61 of the reel holding unit 32 included 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 part 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 worker causes the reel holding unit 32 to hold the reel RL. To do this, first, of the reel holding unit 32 that is in the first position, the second reel holding portion 62 is raised 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 in the second position, the worker lowers the rear end portion 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 part 62 is in an upward position with the tip 83S of the reel operation part 83 facing upward. When the second reel holding part 62 is in the upward position, a working space SGS on which the reel RL can be placed appears in the area on the second reel holding part 62 between the reel operation part 83 (more specifically, the protrusion 83T) and a part of the reel receiving part 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 work space SGS appears on the reel holding unit 32, the worker places the reel RL that will become the current reel RLA in the work space 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] Thus, in this embodiment, the work space SGS that appears by positioning the reel holding unit 32 in the third position is a work space in which a 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 working 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 working space SGS is pulled forward (towards the component supply unit 22) through the carrier tape CT, and thereafter, that reel RL becomes the current reel RLA.

[0058] The reel RL on the work space SGS that 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 work space SGS. In other words, the second reel holding part 62 maintains a state in which it holds the reel RL on the work space SGS even after the component supply unit 22 starts pulling in the carrier tape CT of the reel RL on the work space SGS.

[0059] After inserting the leading end of the carrier tape CT pulled out from the reel RL (current reel RLA) placed in the working space SGS into the component supply unit 22, the worker 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 to be located in the second position (FIG. 15).

[0060] When the reel holding unit 32 is located in the second position, the second reel holding part 62 is in a downward orientation with the tip 83S of the reel operation part 83 facing downward. When the second reel holding part 62 changes from an upward orientation to a downward orientation, the current reel RLA placed in the working space 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 constitute 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 (spacer member indicated by reference symbol "72a" in FIG. 15) provided in the first reel holding portion 61 (constituting the first reel holding portion 61), and also abuts against the tip portion 83S of the reel operation portion 83. As a result, the current reel RLA is supported by the spacer member 72 and the reel operation 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., in the first direction) when viewed from the central axis of the reel RL.

[0063] Furthermore, in this embodiment, the second reel holding portion 62 can be changed between an upward position (first position) in which the tip 83S of the reel operation portion 83 faces upward relative to the first reel holding portion 61, and a downward position (second position) in which the tip 83S of the reel operation portion 83 faces downward. When the second reel holding portion 62 is in the upward position, it creates a working 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 has begun to pull in the carrier tape CT. When in the downward position, the reel RL placed in the working space SGS is guided by the reel operation portion 83 to be sent to the first reel holding portion 61.

[0064] Therefore, the worker can move the reel RL on the work space 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 to the downward position. In other words, the worker can send the reel RL on the work space SGS to the first reel holding part 61 by his / her own will and operation. Therefore, there is no case where the current reel RLA is moved to the first reel holding part 61 that is out of the worker's reach without the worker noticing.

[0065] The refill reel RLB held in the refill reel mounting space HRS of the second reel holding part 62 maintains its state of being held in the refill reel mounting space HRS even when the reel operation part 83 changes from an upward to a downward position. In detail, when the second reel holding part 62 changes from an upward 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 becomes stationary when it abuts against the first spacer 82a and maintains that state (FIG. 15).

[0066] After the worker has sent the reel RL (current reel RLA) on the work space SGS to the first reel holding part 61 as described above, the worker 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 second engagement part 85 provided on the second reel holding part 62 is engaged with the second support bar 49 of the dolly 31, thereby positioning the reel holding unit 32 in 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 to raise the front end side, and the current reel RLA is placed in a state where a part 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 at 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 in a stable state on the spot.

[0068] Even if 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 maintains a state of being positioned within the replenishment reel mounting space HRS (FIG. 16). When 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 at the first position, and supplies the components BH (FIG. 16). When the component supply unit 22 continues supplying the components BH and the current reel RLA runs out of components, that is, when the carrier tape CT of 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 be drawn 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 starts to pull in the carrier tape CT from the refill reel RLB placed in the refill reel mounting space HRS, the previous refill reel RLB is switched to the current reel RLA. The reel RL that has become the new current reel RLA rotates (rotates in place) within the refill reel mounting space HRS. In other words, the second reel holding section 62 maintains a state in which it holds the reel RL on the refill reel mounting space HRS even after the component supply unit 22 starts to pull in the carrier tape CT from the reel RL on the refill reel mounting space HRS.

[0071] When 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 task 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 through 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 the 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 serving as the abutment part (FIG. 18). At the time when the reel holding unit 32 is displaced to the second position, the linear distance connecting the spacer member 72 and the tip part 83S of the reel operation part 83 is smaller than the outer diameter of the reel RL, so that the used reel RL that has moved to the discharge position does not fall but remains at the discharge position.

[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 within 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 takes an upward orientation (FIG. 19).

[0074] When the second reel holding portion 62 is in the upward position, the linear distance connecting the tip portion 83S of the reel operation portion 83 and the spacer member 72 becomes larger than the outer diameter of the reel RL, so that the used reel RL falls downward from the discharge position by 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 backward to move it to the discharge position, and this "backward" 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 in 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 discharged 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 discharged 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 operation 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 for moving the spacer member 72, which serves as the contact portion, rearward to eject the current reel RLA from the first reel holding portion 61. That is, the second reel holding portion 62, which serves as an operating means, swings relative to the first reel holding portion 61, so that 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 moved by the spacer member 72, which serves as the contact portion, to be ejected from the first reel holding portion 61.

[0079] When the used reel RL is discharged to the discharge section 51 by displacing the reel holding unit 32 from the second position to the third position, the worker removes the reel RL that has become the new current reel RLA from the refill reel placement space HRS (arrow L shown in FIG. 19) and places it in the newly appeared working space SGS (FIG. 20). Then, the worker places the new refill reel RLB in the newly vacant refill 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 the component supply operation.

[0080] As described above, the reel holding device 1C in this embodiment comprises a cart 31, a first reel holding section 61 which is mounted so as to be freely swingable relative to the cart 31 and which holds the current reel RLA, and a second reel holding section 62 which is directly connected to the first reel holding section 61 and is freely swingable to hold the reel RLB. When the second reel holding section 62 is operated, the first reel holding section 61 swings relative to the cart 31 in response, thereby ejecting a used reel RL from the first reel holding section 61, or sending the 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, in the reel holding device 1C of this embodiment, the reel RL (current reel RLA) can be easily retrieved at any time even after the reel RL is set in the first reel holding part 61, improving the workability when it becomes necessary to retrieve the reel RL in use, such as during a changeover. Also, the first reel holding part 61 and the second reel holding part 62 form a single reel holding unit 32, and the reel holding unit 32 is configured to be attached to the cart 31, so that the configuration of the reel holding device 1C can be simplified and maintenance can be easily performed.

[0082] 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 part 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 the first reel holding section 61 that holds the current reel RLA, the spacer member 72 as an abutment part that abuts against the outer periphery of the current reel RLA held by the first reel holding section 61, and the second reel holding section 62 as an operation means that moves the spacer member 72 to eject the current reel RLA held by the first reel holding section 61 from the first reel holding section 61. In this embodiment, the abutment part does not abut against the carrier tape CT, so the carrier tape CT is not damaged. This effect is greater for reels RL with larger outer diameters and heavier weights. In addition, since the used reel RL is ejected by the operator's operation at the operator's will, the reel RL will not be ejected without the operator's notice. Therefore, when performing component matching based on the ejected used reel RL, the reel to be matched (used reel RL) is not lost because it is mixed with other reels that have already been ejected, and this is suitable for component matching work.

[0084] Although the embodiment of the present invention has been described so far, the present invention is not limited to the above, and various modifications are possible. For example, in the above embodiment, 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, but 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 around the X-axis independently of the first reel holding portion 61. In the above embodiment, the abutment portion that presses the used reel RL backward constitutes the first reel holding portion 61, so that the abutment portion is moved backward by swinging the first reel holding portion 61 around 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] In the above embodiment, the second reel holding section 62 can be changed between the first position and the second position, but the second reel holding section 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 section 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 was 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 embodiment, the reel holding unit support portion that holds the reel holding units 32 in a direction in which the component supply units 22 are arranged in parallel (parallel direction) is composed 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 extending in the parallel direction of the component supply units 22. And, it is sufficient that the supported portion (the first engagement portion 73 and the second engagement portion 85 in the above embodiment) of the reel holding unit 32 is engaged with the support bar from above.
