1. Embodiment 1-1. Configuration example of setup device 10a The reel loading device 80 loads the reel 70 around which the carrier tape 72 is wound, into the feeder 60. The reel loading device 80 can be applied to the setup device 10a, for example. The setup device 10a automatically loads the reel 70 into the feeder 60 so that the feeder 60 can supply the components 100. The setup device 10a can take various forms as long as it can automatically load the reel 70.

As shown in Figures 1 to 3, the setup device 10a of the embodiment includes a reel attachment/detachment section 20, a reel supply section 30, a reel transfer mechanism 40, and a feeder supply section 50. For ease of explanation, in these figures, the facing direction of the feeder 60 and the reel 70 when the reel 70 is attached to or detached from the feeder 60 is referred to as the first direction (arrow X direction). In addition, within the first direction (arrow X direction), the direction (side) from the feeder 60 toward the reel 70 is referred to as one end side of the first direction (arrow X1 direction), and the direction (side) from the reel 70 toward the feeder 60 is referred to as the other end side of the first direction (arrow X2 direction).

Furthermore, as shown in FIG. 3, the direction perpendicular to the first direction (arrow X direction) in the horizontal plane and the sliding direction of the feeder 60 in the slot 21b is defined as the second direction (arrow Y direction). In addition, within the second direction (arrow Y direction), the sliding direction (side) when the feeder 60 is removed is defined as one end side of the second direction (arrow Y1 direction), and the sliding direction (side) when the feeder 60 is attached is defined as the other end side of the second direction (arrow Y2 direction).

The reel attachment/detachment unit 20 is assembled with various members inside the first housing 11. The first housing 11 is a rectangular parallelepiped case, and is partially open on the other end side in the first direction (arrow X2 direction) and one end side in the second direction (arrow Y1 direction). The reel supply unit 30 is attached to one end side in the second direction (arrow Y1 direction) of the reel attachment/detachment unit 20. The reel supply unit 30 is formed on a box-shaped base 12 that is smaller than the first housing 11. The reel transfer mechanism 40 is provided on a plate seat 12b that extends from the bottom of the base 12 to the other end side in the first direction (arrow X2 direction). The feeder supply unit 50 is attached to the other end side in the first direction (arrow X2 direction) of the reel attachment/detachment unit 20. The feeder supply unit 50 is attached to various members inside the second housing 13 that is smaller than the first housing 11 and has a storage space 13a at the top.

The reel attachment/detachment unit 20 includes a feeder holding unit 21, a reel attachment mechanism 22, and a reel removal mechanism 23. As shown in FIG. 2, the feeder holding unit 21 is disposed inside the first housing 11 at the other end side in the first direction (arrow X2 direction) and one end side in the second direction (arrow Y1 direction). The feeder holding unit 21 holds the feeder 60 in a vertical position at the work execution position. As shown in FIG. 3, the feeder holding unit 21 includes a bottom plate 21a, a slot 21b, and a support plate 21c. The slot 21b is formed in the bottom plate 21a in the shape of a groove extending along the second direction (arrow Y direction). The feeder 60 is inserted from one end side in the second direction (arrow Y1 direction) of the slot 21b toward the other end side in the second direction (arrow Y2 direction) and is held at the work execution position. The support plate 21c is provided to stand up from the bottom plate 21a and contacts the side surface of the other end side in the first direction (arrow X2 direction) of the feeder 60 at the work execution position. The support plate 21c supports the pressing load toward the other end of the first direction (in the direction of the arrow X2) that occurs when the reel 70 is attached to the feeder 60.

The feeder 60 is detachably mounted on the component mounting machine. As shown in FIG. 3, the feeder 60 has a main body 71 to which a reel 70 with a carrier tape 72 wound thereon is attached, and transports the carrier tape 72 to supply the components 100. Each reel 70 is provided with an identification code for identifying the reel 70. The feeder 60 is formed in a flat box shape. The feeder 60 is provided with a reel holding shaft 61 that protrudes from a side plate at the other end side in the first direction (arrow X2 direction) to one end side in the first direction (arrow X1 direction) at a roughly central position when viewed in the first direction (arrow X direction). The reel holding shaft 61 is inserted into a central hole formed in the center of the reel 70 to detachably and rotatably hold the reel 70.

As shown in Figures 4 and 5, the carrier tape 72 includes a base tape 72a, a cover tape 72b, and a bottom tape 72c. The base tape 72a is the base of the carrier tape 72, and is provided with a number of storage sections 72d and a number of feed holes 72e. Each of the multiple storage sections 72d stores a component 100. As shown in Figure 4, a predetermined number of storage sections 72d (e.g., three in this figure) from the tip side of the carrier tape 72 are empty storage sections 72d1 that do not store a component 100. The multiple storage sections 72d are provided at regular intervals (predetermined pitch intervals) in the longitudinal direction of the carrier tape 72 in the center of the width of the base tape 72a.

Each of the multiple feed holes 72e is a through hole and is used when transporting the carrier tape 72 in the transport direction (the other end side of the second direction (arrow Y2 direction)). The multiple feed holes 72e are provided at a predetermined pitch interval in the longitudinal direction of the carrier tape 72 at one end side of the width direction of the base tape 72a. The cover tape 72b closes the storage section 72d of the base tape 72a. The cover tape 72b is attached to the upper surface of both ends of the base tape 72a in the width direction, for example, by adhesive 72f, heat pressing, etc. The bottom tape 72c is attached to the lower surface of the base tape 72a, for example, by adhesive 72f, heat pressing, etc., and prevents the components 100 stored in the storage section 72d from falling off.

The side plate 62 at one end of the feeder 60 in the first direction (the direction of the arrow X1) has an open center to facilitate attachment and detachment of the reel 70. There are multiple types of reels 70 that differ in at least one of the material of the carrier tape 72, the width of the carrier tape 72, the width of the reel 70, and the diameter of the reel 70, and there are multiple types of feeders 60 that correspond to the multiple types of reels 70. The feeder 60 is equipped with a collection position 63, a drive sprocket 64a, and a peeling blade 66.

The pick-up position 63 is provided on the other end side in the second direction (arrow Y2 direction) of the upper surface of the feeder 60, and the component mounting machine picks up the component 100 at the pick-up position 63. The drive sprocket 64a is provided rotatably on the one end side in the second direction (arrow Y1 direction) of the pick-up position 63. The teeth of the drive sprocket 64a engage with the feed hole 72e of the carrier tape 72. The drive sprocket 64a is driven intermittently by a drive motor and transports the carrier tape 72 at a constant pitch. The peeling blade 66 peels the cover tape 72b from the base tape 72a just before the pick-up position 63, allowing the component 100 to be removed. After passing the pick-up position 63, the carrier tape 72 is cut by a tape cutting device provided in the component mounting machine.

Each feeder 60 is provided with an identification code that identifies the feeder 60. The feeder 60 is also provided with a feeder control unit. The feeder control unit stores the identification information of the feeder 60 and the identification information of the reel 70, and controls the component supply operation. When the feeder 60 is held in the feeder holding unit 21, the connectors of both units are engaged, and the feeder control unit is connected to the setup device 10a so as to be able to communicate with it.

The reel attachment mechanism 22 is provided at one end side in the first direction (arrow X1 direction) of the feeder holding section 21. The reel attachment mechanism 22 uses the reel transfer mechanism 40 to change the reel 70 from a horizontal position to a vertical position and attaches the reel 70 to the feeder 60 at the work execution position. The reel attachment mechanism 22 includes a pair of

guide rails

22a, 22a, a moving platform 22b, an attachment material 22c, a placement area 22d, and a temporary placement area 22e. Note that the reel attachment mechanism 22 may be separated into a mechanism for changing the reel 70 from a horizontal position to a vertical position and a mechanism for attaching the reel 70 from the vertical position to the feeder 60.

The pair of

guide rails

22a, 22a extend along the first direction (arrow X direction) at approximately the center of the first housing 11 in the second direction (arrow Y direction) and are arranged parallel to each other at a distance from each other. The movable platform 22b extends along the second direction (arrow Y direction) and is provided so as to straddle the upper side of the pair of

guide rails

22a, 22a. As shown in Figures 1 and 2, the movable platform 22b moves along the pair of

guide rails

22a, 22a and reciprocates between a standby position provided at one end of the first direction (arrow X1 direction) and the feeder holding section 21 provided at the other end of the first direction (arrow X2 direction).

The mounting material 22c is formed in a square rod shape and is provided so as to extend upward from the movable base 22b. The mounting material 22c faces the reel holding shaft 61 of the feeder 60 at the work execution position. Specifically, the mounting material 22c is provided at a position spaced a predetermined distance from the tip of the reel holding shaft 61 toward one end side of the first direction (arrow X1 direction). The mounting material 22c swings between an upright position shown in FIG. 1 and FIG. 2 and a horizontal position leaning toward the other end side of the first direction (arrow X2 direction) around a swing shaft 22c1 provided on the movable base 22b side (arrow SW1 in FIG. 1). A collection section 22c2 is provided at the end of the mounting material 22c on the side opposite to the end on the swing shaft 22c1 side. The collection section 22c2 detachably collects the reel 70. The collection unit 22c2 can use a claw portion that is inserted into the center hole of the reel 70, a gripping mechanism that grips the periphery of the reel 70, or a suction mechanism that uses negative pressure to suction the reel 70.

The placement area 22d is provided on one end side of the pair of

guide rails

22a, 22a in the first direction (arrow X1 direction). In the placement area 22d, the reel 70 to be attached is placed in a horizontal position. The temporary placement area 22e is provided on the other end side of the pair of

guide rails

22a, 22a in the first direction (arrow X2 direction) of the placement area 22d. In the temporary placement area 22e, when the reel attachment mechanism 22 changes the use order of the reels 70, the reels 70 are temporarily placed in a horizontal position to change the use order of the reels 70. The temporary placement area 22e has an area secured so that multiple reels 70 can be temporarily placed. The moving platform 22b and the attachment material 22c move above the placement area 22d and the temporary placement area 22e.

The reel removal mechanism 23 is provided at one end side in the first direction (the direction of the arrow X1) of the feeder holding section 21, and is positioned above the reel attachment mechanism 22. The reel removal mechanism 23 removes the reel 70 from the feeder 60 at the work execution position. The reel removal mechanism 23 includes a guide rail 23a, a movable platform 23b, a removal material 23c, and a collection box 23d.

The guide rail 23a is provided near the ceiling of the first housing 11 and is formed to extend along the second direction (arrow Y direction). The movable platform 23b is formed to extend along the first direction (arrow X direction) and is provided below the guide rail 23a. As shown in Figures 1 and 2, the movable platform 23b moves along the guide rail 23a and reciprocates between a standby position provided at the other end of the second direction (arrow Y2 direction) and the feeder holding section 21.

The detachable member 23c is formed of a thick plate-like member that is longer than the movable platform 23b, and is provided so as to extend along the first direction (arrow X direction) below the movable platform 23b. The detachable member 23c oscillates between the horizontal position shown in FIG. 1 and FIG. 2 and the vertical position in which it is tilted downward, centering on the swing shaft 23c1 provided at the other end side of the movable platform 23b in the first direction (arrow X2 direction) (arrow SW2 in FIG. 1). The end of the detachable member 23c on the side different from the end on the swing shaft 23c1 side is provided with a collection section 23c2. The collection section 23c2 collects the reel 70 in a detachable manner. The collection method of the collection section 23c2 may be the same as or different from that of the collection section 22c2 of the reel attachment mechanism 22.

The collection box 23d is arranged to be located below the detachable material 23c when the movable platform 23b moves to the standby position. The collection box 23d collects the multiple reels 70 that have been removed. The collection box 23d is formed in a box shape that opens upward. Therefore, the collection box 23d can collect the falling reels 70 by the collection section 23c2 of the detachable material 23c releasing the reels 70.

The reel supply unit 30 includes a reel holder 31 that is detachably provided. A pair of

guide plates

12a, 12a extending along the second direction (arrow Y direction) are provided on the upper surface of the base 12 at one end side in the first direction (arrow X1 direction) and the other end side in the first direction (arrow X2 direction). The reel holder 31 is placed between the pair of

guide plates

12a, 12a of the base 12. As shown in FIG. 2, the pair of

guide plates

12a, 12a have tapered surfaces facing each other at one end side in the second direction (arrow Y1 direction), and the distance between the pair of

guide plates

12a, 12a at one end side in the second direction (arrow Y1 direction) is longer than the other end side in the second direction (arrow Y2 direction). This makes it easier to insert the reel holder 31 from one end side in the second direction (arrow Y1 direction) toward the base 12.

The reel holding section 31 holds multiple reels 70 stacked sideways. The reels 70 are not limited to unused reels, and may be used reels with the carrier tape 72 partially used. The reel holding section 31 has a horizontally arranged disk-shaped holding plate 31a and a round bar-shaped holding shaft 31b that is arranged upward from the center of the holding plate 31a and passes through the center hole of the reel 70. Therefore, even if reels 70 with at least one different diameter and width are mixed, the reel holding section 31 can hold multiple reels 70 with the holding shaft 31b passing through the center holes of the multiple reels 70, making it easy to remove the reels 70. An identification code 31c is attached to the top surface of the holding plate 31a. The identification code 31c includes information that identifies the reel holding section 31.

For example, a worker procures multiple reels 70 and performs stacking work by stacking the multiple reels 70 on the reel holding section 31 based on the work instruction data. The work instruction data instructs the work content of the setup work to be performed by the setup device 10a. In other words, the work instruction data associates type information of the multiple reels 70 required as the production of board products by the component mounting machine progresses with type information of the multiple feeders 60 that can be applied to the reels 70. Note that the multiple reels 70 can also be transported using a known unmanned guided vehicle, etc.

The reel transfer mechanism 40 is provided on a plate seat 12b that extends from the bottom of the base 12 to the other end side in the first direction (arrow X2 direction). The reel transfer mechanism 40 includes a support 41, an arm 42, and a collection section 43. The support 41 stands upright vertically upward at the other end side in the second direction (arrow Y2 direction) of the plate seat 12b. The arm 42 is provided so that it can be raised and lowered relative to the support 41. Furthermore, the arm 42 is provided so that it can rotate in a horizontal plane around a rotation axis 44 that is close to the support 41.

The collection unit 43 is provided so as to be extendable and retractable relative to the arm 42. The collection unit 43 collects the reel 70 in a detachable manner. The collection method of the collection unit 43 may be the same as or different from that of the collection unit 22c2 of the reel attachment mechanism 22 and the collection unit 23c2 of the reel removal mechanism 23. The collection unit 43 is also provided with a code reader. The code reader reads the identification code 31c of the reel holding unit 31. Furthermore, the code reader can read the identification code of the top reel 70.

The reel transfer mechanism 40 functions as part of the reel attachment mechanism 22. Specifically, the reel transfer mechanism 40 removes the reel 70 from the reel holding section 31 by driving the arm 42 and the collection section 43. Furthermore, the reel transfer mechanism 40 places the removed reel 70 in a horizontal position in the placement area 22d or the temporary placement area 22e by driving the arm 42 and the collection section 43. The reel transfer mechanism 40 uses the multiple reels 70 stacked in the reel holding section 31 in order, starting from the top.

The feeder supply unit 50 includes a detachable feeder storage unit 51 and a feeder transport unit 52. As shown in FIG. 2, the storage space 13a at the top of the second housing 13 is open at one end in the second direction (the direction of the arrow Y1), and can store multiple (for example, two in the figure) feeder storage units 51 lined up along the first direction (the direction of the arrow X). As shown in FIG. 1, the bottom surface that partitions the storage space 13a is provided with multiple roller conveyors 13b extending along the first direction (the direction of the arrow X), facilitating the storage operation of the feeder storage units 51.

The feeder accommodating section 51 is formed in a box shape with one end side in the second direction (arrow Y1 direction) open. A plurality of slots of the same shape as the slots 21b of the feeder holding section 21 are formed on the bottom surface of the feeder accommodating section 51. The feeder accommodating section 51 can accommodate a plurality of feeders 60 in a vertical position lined up along the first direction (arrow X direction). When the plurality of feeders 60 are accommodated in the feeder accommodating section 51 and the feeder accommodating section 51 is properly stored in the storage space 13a, the feeders 60 and the feeder accommodating section 51 have their connectors fitted together, and the plurality of feeder control sections are connected to the setup device 10a so as to be able to communicate with each other.

The feeder storage unit 51 is provided with an identification code that identifies the feeder storage unit 51. For example, a worker procures multiple feeders 60 to be used based on the work instruction data, and performs storage work to store them in the feeder storage unit 51. The number of feeder storage units 51 that can be stored in the storage space 13a may be one, or three or more. In addition, a publicly known unmanned transport vehicle or the like may be used to transport the multiple feeders 60.

A guide rail 13c is provided at the bottom of one end side in the second direction (arrow Y1 direction) of the storage space 13a of the second housing 13. The guide rail 13c is provided over substantially the entire storage space 13a in the first direction (arrow X direction), and is provided so as to extend to one end side in the second direction (arrow Y1 direction) of the feeder holding unit 21. In addition, a feeder conveying unit 52 is provided on the guide rail 13c. The feeder conveying unit 52 moves along the guide rail 13c, reciprocating between the feeder storage unit 51 and the feeder holding unit 21.

The feeder conveying unit 52 is formed in a box shape with an opening at the other end side in the second direction (arrow Y2 direction). The feeder conveying unit 52 has an internal space that temporarily contains the feeder 60, and a feeder operation mechanism that transports the feeder 60 into the internal space or transports the feeder 60 out of the internal space via the opening. Therefore, the feeder conveying unit 52 can transport the feeder 60 out of the feeder accommodation unit 51 and the feeder holding unit 21, and can transport the feeder 60 into the feeder accommodation unit 51 and the feeder holding unit 21. An openable safety fence is provided at one end side in the second direction (arrow Y1 direction) of the reel supply unit 30 and the feeder supply unit 50, preventing workers from approaching the reel supply unit 30 and the feeder supply unit 50.

1-2. Example of Control of Setup Device 10a The setup device 10a controls the feeder transport unit 52 to transport the feeder 60 corresponding to the uppermost reel 70 of the reel holding unit 31 (step S1 shown in FIG. 6). The feeder transport unit 52 pulls out the feeder 60 from the feeder storage unit 51 and stores it therein, moves to the feeder holding unit 21, and inserts the stored feeder 60 into the feeder holding unit 21. As a result, the feeder 60 is held at the operation position, and the identification code of the feeder 60 is read.

If there is no feeder 60 applicable to the top reel 70 of the reel holding section 31, the reel 70 is placed in the temporary placement area 22e by the reel transfer mechanism 40. The above placement is repeated until an applicable feeder 60 is found, and the feeder 60 corresponding to the top reel 70 of the reel holding section 31 is inserted into the feeder holding section 21. After the control shown in step S1, the setup device 10a executes a first series of controls shown in steps S2 to S5 and a second series of controls shown in steps S11 to S14 in parallel.

In the first series of control, the setup device 10a checks the state of the reel 70 based on the read identification code of the feeder 60 or the identification code of the reel 70, and changes the control according to the state of the reel 70 (step S2). Specifically, if the feeder 60 has been used in a component mounting machine beforehand, the feeder 60 may be equipped with an in-use reel 70 in which the carrier tape 72 has been partially used. In this case, the setup device 10a performs a fastening process to fix the tip of the carrier tape 72 with tape or the like to suppress slack in the carrier tape 72 (step S3). At this time, the setup device 10a can wind the carrier tape 72 onto the reel 70 as necessary.

Next, the reel removal mechanism 23 removes the reel 70 from the feeder 60 (step S4). Specifically, the moving platform 23b moves from the standby position to the feeder holding section 21. Then, when the removal material 23c is swung from the horizontal position to the vertical position, the collection section 23c2 abuts against the reel 70 and collects the reel 70. Next, when the removal material 23c returns from the vertical position to the horizontal position, the collection section 23c2 removes the reel 70 from the reel holding shaft 61 and holds it in a horizontal position. At this time, the setup device 10a deletes the identification information of the reel 70 from the memory section of the feeder control section of the feeder 60. Furthermore, the setup device 10a transmits the identification information of the feeder 60 from which the reel 70 has been removed to a higher-level management device. At that time, the setup device 10a may transmit the identification information of the removed reel 70 together with the identification information of the feeder 60 to a higher-level management device.

Next, the reel removal mechanism 23 collects the reel 70 (step S5). Specifically, first, the moving platform 23b moves from the feeder holding section 21 to the standby position. Then, the collection section 23c2 releases the reel 70. As a result, the released reel 70 falls into the collection box 23d and is collected. Once the reel 70 has been collected, the control of the first series goes into a standby state until the control of the second series ends.

It is possible that the feeder 60 is equipped with a used reel 70 whose carrier tape 72 has been completely used (step S2). In this case, the control shown in step S3 is omitted from the first series of control, and the controls shown in steps S4 and S5 are executed. It is also possible that the feeder 60 is not equipped with a reel 70 (step S2). In this case, the control shown in steps S3 to S5 is omitted from the first series of control.

In the second series of control, the reel transfer mechanism 40 uses the collection unit 43 to collect the top reel 70 of the reel holding unit 31 and places it in the placement area 22d (step S11). The reel transfer mechanism 40 then returns the collection unit 43 to above the reel holding unit 31. If there is no applicable feeder 60, the reel transfer mechanism 40 places the reel 70 in the temporary placement area 22e.

Next, the reel attachment mechanism 22 changes the position of the reel 70 in the placement area 22d (step S12). Specifically, first, the attachment material 22c is changed from an upright position to a horizontal position, and the collection unit 22c2 abuts against the reel 70 to collect the reel 70. Then, the attachment material 22c is returned from the horizontal position to an upright position, and the collection unit 22c2 changes the reel 70 from a sideways position to a vertical position and holds it. When the reel 70 in the temporary placement area 22e is used, the moving platform 22b moves a predetermined distance to the other end side of the first direction (arrow X2 direction) before the attachment material 22c moves from an upright position to a horizontal position. The second series of control is in a standby state until the end condition indicating the completion of the first series of control in step S4 is met. This avoids interference between the reel attachment mechanism 22 and the reel removal mechanism 23.

When the above termination conditions are met, the reel attachment mechanism 22 attaches the reel 70 to the feeder 60 (step S13). Specifically, while the collection unit 22c2 holds the reel 70 in a vertical position, the mobile platform 22b moves to the feeder holding unit 21. As a result, the reel 70 moves toward the reel holding shaft 61 and is attached to the reel holding shaft 61. The movement of the mobile platform 22b can be performed simultaneously with the movement of the mobile platform 23b to the standby position.

When the installation of the reel 70 is completed, the setup device 10a stores the identification information of the reel 70 in the feeder control unit of the feeder 60 to which the reel 70 is attached. Furthermore, the setup device 10a transmits the identification information of the feeder 60 and the identification information of the reel 70 mounted on the feeder 60 in association with each other to a higher-level management device. The movable table 22b also returns to the standby position. Next, the setup device 10a feeds the carrier tape 72 until the feed hole 72e of the carrier tape 72 engages with the teeth of the manual sprocket 64b described below (step S14).

When the first and second series of control are completed, the feeder conveying unit 52 pulls out the feeder 60 from the feeder holding unit 21, stores it inside, moves to the feeder storage unit 51, and inserts the stored feeder 60 into the feeder storage unit 51 (step S6). This completes the setup work for one feeder 60. The setup device 10a determines whether the setup work for all feeders 60 is complete (step S7). If the setup work for all feeders 60 is complete (Yes in step S7), the control by the setup device 10a is temporarily terminated. If the setup work for all feeders 60 is not complete (No in step S7), the control by the setup device 10a returns to the control shown in step S1, and the previously described control is repeated until the setup work for all feeders 60 is complete.

When control by the setup device 10a is completed, for example, the worker transports the feeder accommodation section 51 housing the set-up feeder 60 to the component mounting machine and changes the setup of the feeder 60. If a reel 70 is placed in the temporary placement area 22e, the reel 70 becomes usable when the worker stores a feeder 60 applicable to that reel 70 in the feeder accommodation section 51. In addition, the reel 70 that remains unused in the temporary placement area 22e is returned to the reel holding section 31 by the reel transfer mechanism 40 and is collected by the worker. Furthermore, the above-mentioned transport work by the worker can also be automated by using a known unmanned guided vehicle, etc.

1-3. Example of the configuration of the reel loading device 80 When loading the reel 70 into the feeder 60, it is necessary to position the leading end 72t of the carrier tape 72 and the peeling blade 66 that peels off the cover tape 72b. Therefore, the setup device 10a is provided with a reel loading device 80. The reel loading device 80 loads the reel 70 around which the carrier tape 72 is wound into the feeder 60. The reel loading device 80 can also perform the above positioning. As described above, in the setup device 10a, the loading operation of loading the reel 70 into the feeder 60 is also automated.

The reel loading device 80 includes a positioning mechanism 83. The reel loading device 80 may also include an operation mechanism 81. The reel loading device 80 may also include a detection mechanism 82. The reel loading device 80 may also include a transport unit 84. As shown in FIGS. 7 to 9, the reel loading device 80 of the embodiment includes an operation mechanism 81, a detection mechanism 82, a positioning mechanism 83, and a transport unit 84. As shown in FIG. 10, the operation mechanism 81 of the embodiment, the moving unit 82c of the detection mechanism 82, and the pressing member driving unit 83b of the positioning mechanism 83 are provided in a non-operation area AR1 where the operator does not operate the feeder 60. FIG. 10 shows a schematic view of the feeder 60 and the reel loading device 80 viewed from above in the vertical direction. As described later, the non-operation area AR1 includes an area where no operation is required when the operator loads the reel 70.

The transport unit 84 can be provided in various control devices, management devices, etc. The transport unit 84 can also be formed on the cloud. As shown in FIG. 7, the transport unit 84 of the embodiment is provided in the control device of the setup device 10a. The reel loading device 80 of the embodiment executes control according to the flowchart shown in FIG. 11. The operation mechanism 81 performs the processes and judgments shown in steps S21 to S24. The detection mechanism 82 performs the judgments shown in step S25. The positioning mechanism 83 performs the processes and judgments shown in steps S26 to S29. The transport unit 84 performs the process shown in step S30.

1-3-1. Operation mechanism 81
12 and 13, the feeder 60 includes a driving sprocket 64a, a manual sprocket 64b, and an operating unit 65. As described above, the driving sprocket 64a drives the carrier tape 72. The manual sprocket 64b is a sprocket provided upstream of the driving sprocket 64a in the transport direction of the carrier tape 72 (corresponding to one end side in the second direction (the direction of the arrow Y1) in the setup device 10a. The same applies below.) Similar to the drive sprocket 64a, the teeth of the manual sprocket 64b engage with the feed holes 72e of the carrier tape 72.

The operating unit 65 refers to a portion where an operator can rotate the manual sprocket 64b. When the operator rotates the operating unit 65, the manual sprocket 64b rotates and the carrier tape 72 can be transported from the manual sprocket 64b to the drive sprocket 64a. As a result, the carrier tape 72 is transported to the peeling blade 66 shown in FIG. 14, which peels off the cover tape 72b. In order to automate the above-mentioned operation by the operator, the reel loading device 80 is provided with an operating mechanism 81.

The operating mechanism 81 rotates the manual sprocket 64b instead of the operator to transport the carrier tape 72 from the manual sprocket 64b to the drive sprocket 64a. The operating mechanism 81 can take various forms as long as it can transport the carrier tape 72 as described above. The operating mechanism 81 of the embodiment includes a convex member 81a, a convex member drive unit 81b, and a detection unit 81c. For example, as shown in FIG. 13, the manual sprocket 64b includes a polygonal hole 64b1. The hole 64b1 is formed, for example, in a hexagonal shape.

In the above embodiment, as shown in Figs. 15 and 16, the operating mechanism 81 may include a convex member 81a and a convex member drive unit 81b. The convex member 81a is a member that can fit into the hole 64b1. For example, if the hole 64b1 is formed in a hexagonal shape, the convex member 81a may be formed in a hexagonal column shape. The convex member drive unit 81b moves the convex member 81a toward the hole 64b1 and rotates it while it is engaged with the hole 64b1, thereby rotating the manual sprocket 64b.

The convex member drive unit 81b may take various forms as long as it can move the convex member 81a and rotate the manual sprocket 64b as described above. The convex member drive unit 81b can move the convex member 81a by means of a cylinder, for example. The convex member drive unit 81b can also rotate the convex member 81a by means of an electric motor, for example. In this way, the carrier tape 72 is transported from the manual sprocket 64b to the peeling blade 66.

If the convex member 81a rotates without being engaged with the hole 64b1, it will spin freely and will not be able to rotate the manual sprocket 64b. Therefore, the operating mechanism 81 may include a detector 81c. The detector 81c detects the engaged state in which the convex member 81a is engaged with the hole 64b1. The detector 81c may take various forms as long as it can detect the engaged state. As shown in Figures 15 and 16, the convex member 81a in this embodiment is provided at the tip of a stepped member 92 that is movable relative to a base 91 fixed to the shaft 81b1 of the convex member drive unit 81b.

The stepped member 92 includes a first member 92a, a second member 92b, and a biasing member 92c. The first member 92a is a member provided on the side of the base portion 91. The second member 92b is a member with a larger diameter than the first member 92a and provided on the side of the convex member 81a. The biasing member 92c is a member that biases the first member 92a, the second member 92b, and the convex member 81a in the direction of the hole portion 64b1. For example, the first member 92a and the second member 92b are made of metal and formed into a cylindrical shape. The biasing member 92c can be a spring member.

The detection unit 81c is a proximity sensor that moves with the base portion 91 when the convex member drive unit 81b moves the convex member 81a toward the hole portion 64b1 to fit into the hole portion 64b1, and can detect the second member 92b that is closer than the first member 92a. Specifically, the convex member drive unit 81b moves the convex member 81a toward the hole portion 64b1 (step S21 shown in FIG. 11). When the convex member 81a fits into the hole portion 64b1, the detection unit 81c detects the fitted state by not detecting the second member 92b facing the first member 92a. When the fitting state is detected by the detection unit 81c (Yes in step S22), the convex member drive unit 81b rotates the manual sprocket 64b by rotating the convex member 81a (step S23).

When the convex member 81a is not engaged with the hole 64b1, the biasing member 92c shrinks by the amount that the convex member 81a cannot enter the hole 64b1, and the convex member 81a moves relative to the base 91. As a result, the detection unit 81c can detect a non-engaged state in which the convex member 81a is not engaged with the hole 64b1 by facing the second member 92b and detecting the second member 92b. When the detection unit 81c detects a non-engaged state (No in step S22), the convex member drive unit 81b rotates the convex member 81a to change the rotational position (angle) of the convex member 81a until the detection unit 81c detects an engaged state (step S24).

In this way, when the convex member 81a is engaged with the hole portion 64b1, the detection unit 81c detects the engaged state by not detecting the second member 92b while facing the first member 92a. Also, when the convex member 81a is not engaged with the hole portion 64b1, the detection unit 81c detects the non-engaged state by detecting the second member 92b while facing the second member 92b through relative movement. This allows the convex member drive unit 81b to reliably rotate the manual sprocket 64b with the convex member 81a engaged with the hole portion 64b1.

1-3-2. Detection mechanism 82
The detection mechanism 82 detects a pre-arrival state immediately before the leading end 72t of the carrier tape 72 reaches the blade tip 66a of the peeling blade 66. The detection mechanism 82 may take various forms as long as it is capable of detecting the pre-arrival state.

8 and 9, for example, the detection mechanism 82 includes an imaging device 82a, a detection unit 82b, and a moving unit 82c. The imaging device 82a may be any imaging device capable of imaging the carrier tape 72, and any known imaging device may be used. The imaging device 82a can image the carrier tape 72 from above in the vertical direction. The detection unit 82b processes the image data of the carrier tape 72 acquired by the imaging device 82a to recognize the positional relationship between the tip 72t of the carrier tape 72 and the blade tip 66a of the peeling blade 66, and detects the pre-arrival state based on the recognized positional relationship. The moving unit 82c moves the imaging device 82a above the carrier tape 72 when imaging the carrier tape 72.

As shown in FIG. 14, for example, the tape guide 67 to which the peeling blade 66 is attached has a window 67a that can recognize the feed hole 72e of the carrier tape 72 at a predetermined position upstream of the peeling blade 66 in the transport direction of the carrier tape 72. In this case, when the detection unit 82b recognizes the feed hole 72e of the carrier tape 72 in the window 67a, it can recognize the positional relationship in which the tip 72t of the carrier tape 72 reaches the cutting edge 66a of the peeling blade 66 and detect the pre-arrival state. Note that when the detection unit 82b does not recognize the feed hole 72e of the carrier tape 72 in the window 67a, it can detect the non-pre-arrival state, which is not in the above positional relationship.

The detection mechanism 82 can also include a light projector capable of projecting light onto the carrier tape 72 at a predetermined position upstream of the peeling blade 66 in the transport direction of the carrier tape 72, and a light receiver that receives light projected from the light projector and reflected by the carrier tape 72. In this case, the detection mechanism 82 can determine the presence or absence of the carrier tape 72 based on the intensity of the reflected light received by the light receiver. Therefore, when the intensity of the reflected light received by the light receiver is equal to or greater than a predetermined level, the detection unit 82b can recognize the positional relationship in which the tip 72t of the carrier tape 72 reaches the cutting edge 66a of the peeling blade 66, and detect the pre-arrival state.

1-3-3. Positioning mechanism 83 and conveying unit 84
When loading the reel 70 into the feeder 60, the positioning mechanism 83 positions the peeling blade 66 so that the blade tip 66a of the peeling blade 66 enters the tip 72t of the carrier tape 72 before the tip 72t of the carrier tape 72 reaches the peeling blade 66 that peels off the cover tape 72b. The positioning mechanism 83 may take various forms as long as it can position the peeling blade 66 as described above. For example, the positioning mechanism 83 of the embodiment includes a pressing member 83a, a pressing member driving unit 83b, an adjustment unit 83c, and a confirmation unit 83d.

As shown in Figures 17 and 18, for example, the positioning mechanism 83 includes a pressing member 83a and a pressing member drive unit 83b. The pressing member 83a is a member capable of pressing a specific portion 67b of the tape guide 67 to which the peeling blade 66 is attached. The pressing member drive unit 83b moves the pressing member 83a to the specific portion 67b of the tape guide 67 to press the specific portion 67b. For example, the pressing member 83a is provided so as to be rotatable about a fulcrum 83a1.

One end of the pressing member 83a is connected to the pressing member drive unit 83b. The pressing member drive unit 83b moves one end of the pressing member 83a vertically upwards, for example, by means of a cylinder. This causes the pressing member 83a to rotate around a fulcrum 83a1. The other end of the pressing member 83a is formed in an L-shape, and the tip can press against a specified portion 67b. This allows the peeling blade 66 to be positioned vertically.

If the detection mechanism 82 detects the pre-arrival state (Yes in step S25 shown in FIG. 11), the positioning mechanism 83 presses a predetermined portion 67b of the tape guide 67 to position the peeling blade 66 (step S26). If the detection mechanism 82 does not detect the pre-arrival state (No in step S25), the operation mechanism 81 rotates the manual sprocket 64b until the pre-arrival state is detected.

The positioning mechanism 83 may also include an adjustment unit 83c. The adjustment unit 83c adjusts the amount of pressure applied when the pressing member 83a presses the specific portion 67b (step S27). The adjustment unit 83c may take various forms as long as it can adjust the amount of pressure. As shown in Figures 19 and 20, for example, the adjustment unit 83c is provided so as to be rotatable by the pressing member drive unit 83b.

The adjustment portion 83c is formed in an elliptical shape when viewed in the direction of the rotation axis, and the amount of descent of the pressing member 83a can be adjusted depending on the rotation position (angle). The pressing member 83a has a protrusion 83a2 that protrudes downward. The protrusion 83a2 descends by the amount of descent adjusted by the adjustment portion 83c, and can press against a specified portion 67b of the tape guide 67.

The positioning mechanism 83 may also include a confirmation unit 83d. The confirmation unit 83d confirms the peeled state in which the cover tape 72b has been peeled off by the peeling blade 66 (step S28). The confirmation unit 83d may take various forms as long as it can confirm the peeled state (the state in which the cover tape 72b has been properly peeled off). As shown in Figures 8 and 9, for example, the confirmation unit 83d may confirm the peeled state using an imaging device 82a. Specifically, the confirmation unit 83d may capture an image of the area through which the peeled cover tape 72b passes using the imaging device 82a. The confirmation unit 83d may then perform image processing on the image data of the area acquired by the imaging device 82a to confirm the peeled state.

If the confirmation unit 83d confirms that the peeled state has occurred (Yes in step S28), the pressing member driving unit 83b stops pressing the predetermined area 67b with the pressing member 83a (step S29). In addition, the conveying unit 84 causes the feeder 60 to convey the carrier tape 72 until the part 100 reaches the pick-up position 63 where the part 100 is picked (step S30). Specifically, the conveying unit 84 rotates the drive sprocket 64a to convey the carrier tape 72.

For example, the transport unit 84 can capture an image of the collection position 63 using the imaging device 82a already described. The transport unit 84 can then process the image data of the collection position 63 captured by the imaging device 82a to confirm the arrival of the part 100. The transport unit 84 can also confirm the arrival of the part 100 using a height sensor provided at the collection position 63. Note that if the peeling state is not confirmed by the confirmation unit 83d (No in step S28), the specified portion 67b continues to be pressed and the manual sprocket 64b continues to rotate until the peeling state is confirmed.

1-3-4. Example of arrangement of reel loading device 80 As shown in FIG. 2, in the embodiment, the feeder 60 is provided inside the first housing 11. Therefore, when loading the reel 70 into the feeder 60, the worker is usually unable to operate the feeder 60. However, for example, if a problem occurs during the loading operation, the setup device 10a may supply only the driving power for driving the feeder 60 and stop the driving power of other mechanisms, implementing safety measures for the worker, and then permitting the worker to continue working.

In this case, the operating mechanism 81 is preferably provided in the non-operation area AR1 where the worker does not operate the feeder 60. Similarly, the moving part 82c of the detection mechanism 82 is preferably provided in the non-operation area AR1. Also, the pressing member driving part 83b of the positioning mechanism 83 is preferably provided in the non-operation area AR1. In either case, the reel loading device 80 can be placed in an area that does not affect the work of the worker.

Specifically, as shown in FIG. 3, the reel 70 is attached to the reel holding shaft 61. Therefore, as shown in FIG. 8 and FIG. 10, the side of the feeder 60 from which the reel holding shaft 61 protrudes corresponds to the operation area AR2 where an operator may operate the feeder 60. Therefore, as shown in FIG. 10, the non-operation area AR1 can be set in the area opposite the side from which the reel holding shaft 61 protrudes. The non-operation area AR1 includes, for example, an area where no operation is required when the operator loads the reel 70.

What has been said above about the non-operation area AR1 is particularly useful when the feeder 60 is exposed and not covered by a housing. For example, it is assumed that the feeder 60 shown in FIG. 8 is provided on a workbench and an operator loads the reel 70 into the feeder 60. Note that the matters described in this specification can be selected and combined as appropriate. For example, in a feeder 60 that does not have a manual sprocket 64b and an operating unit 65, the operating mechanism 81 can be omitted.

2. Example of Effects of the Embodiment According to the reel loading device 80, the peeling blade 66 can be positioned so that the cutting edge 66a of the peeling blade 66 enters the leading end 72t of the carrier tape 72 before the leading end 72t of the carrier tape 72 reaches the peeling blade 66 that peels off the cover tape 72b.
