The feeder control section stores the identification information of feeder 60 and the identification information of reel 70, and controls the component supply operation. When feeder 60 is held by feeder holding section 21, the connectors are fitted to each other, and the feeder control section is communicably connected to setup device 10a.
[0040] Reel attachment mechanism 22 is provided on the first end side (arrow X1 direction) in the first direction of feeder holding section 21. Reel attachment mechanism 22 changes reel 70 from a horizontal posture to a vertical posture and attaches reel 70 to feeder 60 at the work execution position using reel transfer mechanism 40. Reel attachment mechanism 22 includes pair of guide rails 22a and 22a, moving table 22b, attachment material 22c, placement area 22d, and temporary placement area 22e. Reel attachment mechanism 22 may be configured such that a mechanism that changes reel 70 from the horizontal posture to the vertical posture and a mechanism that attaches reel 70 in the vertical posture to feeder 60 are separated.
[0041] Pair of guide rails 22a and 22a extends along the first direction (arrow X direction) at a substantially central position in the second direction (arrow Y direction) of first housing 11, and is disposed in parallel to be separated from each other. Moving table 22b extends along the second direction (arrow Y direction), and is provided to straddle the upper sides of pair of guide rails 22a and 22a. As illustrated in
[0042] Attachment material 22c is formed in a square bar shape, and is provided to extend upward from moving table 22b. Attachment material 22c faces reel holding shaft 61 of feeder 60 at the work execution position. Specifically, attachment material 22c is provided at a position separated by a predetermined distance from a tip end portion of reel holding shaft 61 toward the first end side (arrow X1 direction) in the first direction. Attachment material 22c swings (arrow SW1 in
[0043] Placement area 22d is provided on the first end side (arrow X1 direction) in the first direction in pair of guide rails 22a and 22a. In placement area 22d, reel 70 to be attached is placed in a horizontal posture. Temporary placement area 22e is provided on pair of guide rails 22a and 22a on the second end side (arrow X2 direction) in the first direction with respect to placement area 22d. In temporary placement area 22e, when reel attachment mechanism 22 changes the use order of reels 70, reels 70 are temporarily placed in the horizontal posture and the use order of reels 70 is changed. In temporary placement area 22e, an area where multiple reels 70 can be temporarily placed is secured. Moving table 22b and attachment material 22c move above placement area 22d and temporary placement area 22e.
[0044] Reel detachment mechanism 23 is provided on the first end side (arrow X1 direction) in the first direction of feeder holding section 21, and is disposed above reel attachment mechanism 22. Reel detachment mechanism 23 detaches reel 70 from feeder 60 at the work execution position.

[0045] Guide rail 23a is provided in the vicinity of the ceiling of first housing 11, and is formed to extend along the second direction (arrow Y direction). Moving table 23b is formed to extend along the first direction (arrow X direction), and is provided below guide rail 23a. As illustrated in
[0046] Detachment material 23c is formed of a thick plate-shaped member longer than moving table 23b, and is provided below moving table 23b to extend along the first direction (arrow X direction). Detachment material 23c swings (arrow SW2 in
[0047] Retrieval box 23d is provided to be positioned below detachment material 23c when moving table 23b is moved to the standby position. Retrieval box 23d retrieves multiple detached reels 70. Retrieval box 23d is formed in a box shape opening upward. Accordingly, retrieval box 23d can retrieve reel 70 that falls off when collection section 23c2 of detachment material 23c releases reel 70.
[0048] Reel supply section 30 includes reel holding section 31 that is detachably provided. Pair of guide plates 12a and 12a extending along the second direction (arrow Y direction) is provided on the first end side (arrow X1 direction) in the first direction and the second end side (arrow X2 direction) in the first direction of the upper surface of base 12. Reel holding section 31 is placed between pair of guide plates 12a and 12a of base 12. As illustrated in
[0049] Reel holding section 31 stacks and holds multiple reels 70 in a horizontal posture. Reel 70 is not limited to an unused reel, and may be a reel in use in which carrier tape 72 has been used halfway. Reel holding section 31 includes circular plate-shaped holding plate 31a provided horizontally, and round rod-shaped holding shaft 31b provided upward from the center of holding plate 31a and penetrating through the center hole of reel 70. Accordingly, reel holding section 31 can hold multiple reels 70 in a state where holding shaft 31b penetrates through the center holes of multiple reels 70 even when reels 70 having at least one of different diameter and different width dimension coexist, and reels 70 can be easily taken out. Identification code 31c is attached to an upper surface of holding plate 31a. Identification code 31c includes information for specifying reel holding section 31.
[0050] For example, the worker procures multiple reels 70 based on work instruction data, and executes a stacking work of stacking multiple reels 70 on reel holding section 31. The work instruction data indicates a work content of the setup work executed by setup device 10a. That is, in the work instruction data, type information of multiple reels 70 required with the progress of the production of board products by the component mounter is associated with type information of multiple feeders 60 applicable to reels 70. A known automated guided vehicle or the like may also be used to convey multiple reels 70.
[0051] Reel transfer mechanism 40 is provided on plate base 12b extending from the bottom portion of base 12 to the second end side (arrow X2 direction) in the first direction. Reel transfer mechanism 40 includes support column 41, arm 42, and collection section 43. Support column 41 stands upward in the vertical direction on the second end side (arrow Y2 direction) in the second direction of plate base 12b. Arm 42 is provided to be liftable and lowerable with respect to support column 41. Further, arm 42 is rotatably provided on a horizontal plane around rotation axis 44 close to support column 41.
[0052] Collection section 43 is provided to be extendable and contractible with respect to arm 42. Collection section 43 detachably collects reel 70. The collecting method of collection section 43 may be the same as or different from the collecting method of collection section 22c2 of reel attachment mechanism 22 and collection section 23c2 of reel detachment mechanism 23. Collection section 43 is provided with a code reader. The code reader reads identification code 31c of reel holding section 31. Further, the code reader can read the identification code of uppermost reel 70.
[0053] Reel transfer mechanism 40 functions as a part of reel attachment mechanism 22. Specifically, reel transfer mechanism 40 takes out reel 70 from reel holding section 31 by driving arm 42 and collection section 43. Further, reel transfer mechanism 40 places taken out reel 70 in placement area 22d or temporary placement area 22e in the state of the horizontal posture by driving arm 42 and collection section 43. Reel transfer mechanism 40 sequentially uses multiple reels 70 stacked on reel holding section 31 from the uppermost.
[0054] Feeder supply section 50 includes feeder accommodation section 51 that is detachably provided and feeder conveyance section 52. As illustrated in
[0055] Feeder accommodation section 51 is formed in a box shape whose first end side (arrow Y1 direction) in the second direction is opened. Multiple slots having the same shape as slot 21b of feeder holding section 21 are formed on the bottom surface of feeder accommodation section 51. Feeder accommodation section 51 can accommodate multiple feeders 60 in a vertical posture arranged along the first direction (arrow X direction). When multiple feeders 60 are accommodated in feeder accommodation section 51 and feeder accommodation section 51 is properly stored in storage space 13a, the connectors of feeder 60 and feeder accommodation section 51 are fitted to each other, and multiple feeder control sections are communicably connected to setup device 10a.
[0056] An identification code for identifying feeder accommodation section 51 is attached to feeder accommodation section 51. For example, the worker procures multiple feeders 60 to be used based on the work instruction data, and executes the accommodation work of accommodating feeders 60 in feeder accommodation section 51. The number of feeder accommodation sections 51 that can be accommodated in storage space 13a may be one or three or more. A known automated guided vehicle or the like can also be used to convey multiple feeders 60.
[0057] Guide rail 13c is provided in a lower portion on the first end side (arrow Y1 direction) in the second direction of storage space 13a of second housing 13. Guide rail 13c is provided in storage space 13a over substantially the entire first direction (arrow X direction), and is provided to extend to the first end side (arrow Y1 direction) in the second direction of feeder holding section 21. Guide rail 13c is provided with feeder conveyance section 52. Feeder conveyance section 52 moves along guide rail 13c and reciprocates between feeder accommodation section 51 and feeder holding section 21.
[0058] Feeder conveyance section 52 is formed in a box shape having an opening portion on the second end side (arrow Y2 direction) in the second direction. Feeder conveyance section 52 includes a built-in space that temporarily incorporates feeder 60, and a feeder operation mechanism that conveys feeder 60 into the built-in space through the opening portion and conveys feeder 60 out of the built-in space. Accordingly, feeder conveyance section 52 can convey feeder 60 out of feeder accommodation section 51 and feeder holding section 21, and can convey feeder 60 into feeder accommodation section 51 and feeder holding section 21. An openable and closable safety fence is provided on the first end side (arrow Y1 direction) in the second direction of reel supply section 30 and feeder supply section 50, and the approach of the worker to reel supply section 30 and feeder supply section 50 is suppressed.
1-2. Control Example of Setup Device 10a
[0059] Setup device 10a causes feeder conveyance section 52 to convey feeder 60 corresponding to uppermost reel 70 of reel holding section 31 (step S1 illustrated in
[0060] When there is no feeder 60 applicable to uppermost reel 70 of reel holding section 31, reel 70 is placed in temporary placement area 22e by reel transfer mechanism 40. The above-described placement is repeated until applicable feeder 60 is present, and feeder 60 corresponding to uppermost reel 70 of reel holding section 31 is inserted into feeder holding section 21. After the control illustrated in step S1, in setup device 10a, a first-series control illustrated in steps S2 to S5 and a second-series control illustrated in steps S11 to S14 are executed in parallel.
[0061] In the first-series control, setup device 10a confirms the state of reel 70 based on the read identification code of feeder 60 or the read identification code of reel 70, and changes the control according to the state of reel 70 (step S2). Specifically, when feeder 60 is used in the component mounter in advance, there is a possibility that reel 70 in use in which carrier tape 72 has been used halfway is provided in feeder 60. In this case, setup device 10a executes a fastening process of fixing the tip end portion of carrier tape 72 with a tape or the like to suppress slack of carrier tape 72 (step S3). At this time, setup device 10a can wind carrier tape 72 on reel 70 as necessary.
[0062] Next, reel detachment mechanism 23 detaches reel 70 from feeder 60 (step S4). Specifically, moving table 23b moves from the standby position to feeder holding section 21. Then, when detachment material 23c is swung from the horizontal posture to the vertical posture, collection section 23c2 comes into contact with reel 70 and collects reel 70. Then, when detachment material 23c returns from the vertical posture to the horizontal posture, collection section 23c2 pulls out reel 70 from reel holding shaft 61 and holds reel 70 in the horizontal posture. In this case, setup device 10a deletes the identification information of reel 70 from the storage section of the feeder control section of feeder 60. Further, setup device 10a transmits the identification information of feeder 60, from which reel 70 has been detached, to a higher-level management device. In this case, setup device 10a may transmit the identification information of detached reel 70 together with the identification information of feeder 60 to the higher-level management device.
[0063] Next, reel detachment mechanism 23 retrieves reel 70 (step S5). Specifically, first, moving table 23b moves from feeder holding section 21 to the standby position. Then, collection section 23c2 releases reel 70. Thus, released reel 70 falls into retrieval box 23d and is retrieved. When reel 70 is retrieved, the first-series control is in a standby state until the second-series control ends.
[0064] There is a possibility that feeder 60 is provided with used reel 70 in which all of carrier tape 72 has been used (step S2). In this case, in the first-series control, the control illustrated in step S3 is omitted, and the controls illustrated in step S4 and step S5 are executed. There is a possibility that feeder 60 is not provided with reel 70 (step S2). In this case, in the first-series control, the controls illustrated in steps S3 to S5 are omitted.
[0065] In the second-series control, reel transfer mechanism 40 collects uppermost reel 70 of reel holding section 31 using collection section 43, and places reel 70 in placement area 22d (step S11). Then, reel transfer mechanism 40 returns collection section 43 to above reel holding section 31. When there is no applicable feeder 60, reel transfer mechanism 40 places reel 70 in temporary placement area 22e.
[0066] Next, reel attachment mechanism 22 changes the posture of reel 70 in placement area 22d (step S12). Specifically, first, attachment material 22c is changed from the upright posture to the horizontal posture, and collection section 22c2 comes into contact with reel 70 and collects reel 70. Then, attachment material 22c is returned from the horizontal posture to the upright posture, and collection section 22c2 changes reel 70 from the horizontal posture to the vertical posture and holds reel 70. When reel 70 in temporary placement area 22e is used, moving table 22b moves to the second end side (arrow X2 direction) in the first direction by a predetermined distance before attachment material 22c shifts from the upright posture to the horizontal posture. The second-series control is in a standby state until an end condition indicating the completion of the control of step S4 of the first-series is satisfied. This avoids interference between reel attachment mechanism 22 and reel detachment mechanism 23.
[0067] When the end condition described above is satisfied, reel attachment mechanism 22 attaches reel 70 to feeder 60 (step S13). Specifically, in a state where collection section 22c2 holds reel 70 in the vertical posture, moving table 22b moves to feeder holding section 21. Accordingly, reel 70 moves toward reel holding shaft 61 and is attached to reel holding shaft 61. The movement of moving table 22b can be performed simultaneously with the movement of moving table 23b to the standby position.
[0068] When the attachment of reel 70 ends, setup device 10a stores the identification information of reel 70 in the feeder control section of feeder 60 to which reel 70 is attached. Further, setup device 10a transmits the identification information of feeder 60 and the identification information of reel 70 provided in feeder 60 to the higher-level management device in association with each other. Moving table 22b returns to the standby position. Next, setup device 10a feeds carrier tape 72 until feed hole 72e of carrier tape 72 engages with the teeth portion of manual sprocket 64b described later (step S14).
[0069] When the first-series control and the second-series control end, feeder conveyance section 52 pulls out feeder 60 from feeder holding section 21, incorporates feeder 60 therein, moves feeder 60 to feeder accommodation section 51, and inserts incorporated feeder 60 into feeder accommodation section 51 (step S6). Thus, the setup work for one feeder 60 ends. Setup device 10a determines whether the setup work for all feeders 60 has ended (step S7). When the setup work for all feeders 60 has ended (Yes in step S7), the control by setup device 10a temporarily ends. When the setup work for all feeders 60 has not ended (No in step S7), the control by setup device 10a returns to the control illustrated in step S1, and the control described above is repeated until the setup work for all feeders 60 ends.
[0070] When the control by setup device 10a ends, for example, the worker conveys feeder accommodation section 51 accommodating feeder 60 that has been set up to the component mounter, and performs the setup change of feeder 60. In a case where reel 70 is placed in temporary placement area 22e, reel 70 becomes usable when the worker accommodates feeder 60 applicable to reel 70 in feeder accommodation section 51. Further, reel 70 left unused in temporary placement area 22e is returned to reel holding section 31 by reel transfer mechanism 40 and retrieved by the worker. Further, the above-described conveyance work performed by the worker can also be automated using a known automated guided vehicle or the like.
1-3. Configuration Example of Reel Loading Device 80
[0071] When loading reel 70 into feeder 60, it is necessary to perform positioning of tip end portion 72t of carrier tape 72 and peeling blade 66 for peeling cover tape 72b. Therefore, setup device 10a is provided with reel loading device 80. Reel loading device 80 loads reel 70, on which carrier tape 72 is wound, into feeder 60. Further, reel loading device 80 can perform the above-described positioning. As described above, in setup device 10a, loading work of loading reel 70 into feeder 60 is also automated.
[0072] Reel loading device 80 includes positioning mechanism 83. Reel loading device 80 can also include operation mechanism 81. Further, reel loading device 80 may include sensing mechanism 82. Reel loading device 80 can also include conveyance section 84. As shown in
[0073] Conveyance section 84 can be provided in various control devices, management devices, or the like. Conveyance section 84 can also be formed on a cloud. As illustrated in
1-3-1. Operation Mechanism 81
[0074] As illustrated in
[0075] Operation section 65 is a section where the worker can rotate manual sprocket 64b. When the worker rotates operation section 65, manual sprocket 64b rotates and carrier tape 72 can be conveyed from manual sprocket 64b to drive sprocket 64a. Accordingly, carrier tape 72 is conveyed to peeling blade 66 illustrated in
[0076] Operation mechanism 81 rotates manual sprocket 64b to convey carrier tape 72 from manual sprocket 64b to drive sprocket 64a instead of the worker. Operation mechanism 81 need only be capable of conveying carrier tape 72 as described above, and may take various configurations. Operation mechanism 81 of the embodiment includes protrusion member 81a, protrusion member drive section 81b, and detection section 81c. For example, as illustrated in
[0077] In the above embodiment, as illustrated in
[0078] Protrusion member drive section 81b need only be capable of moving protrusion member 81a as described above and rotating manual sprocket 64b, and may take various configurations. Protrusion member drive section 81b can move protrusion member 81a by, for example, a cylinder. Further, protrusion member drive section 81b can rotate protrusion member 81a by, for example, an electric motor. Accordingly, carrier tape 72 is conveyed from manual sprocket 64b to peeling blade 66.
[0079] When protrusion member 81a rotates in a state of not being fitted into hole portion 64b1, protrusion member 81a idles and cannot rotate manual sprocket 64b. Therefore, operation mechanism 81 may include detection section 81c. Detection section 81c detects a fitted state in which protrusion member 81a is fitted into hole portion 64b1. Detection section 81c need only be capable of detecting the fitted state, and may take various configurations. As illustrated in
[0080] Stepped member 92 includes first member 92a, second member 92b, and biasing member 92c. First member 92a is a member provided on base portion 91 side. Second member 92b is a member having a larger diameter than first member 92a and is provided on protrusion member 81a side. Biasing member 92c is a member that biases first member 92a, second member 92b, and protrusion member 81a in the direction of hole portion 64b1. For example, first member 92a and second member 92b are made of metal and formed in a cylindrical shape. A spring member can be used as biasing member 92c.
[0081] Detection section 81c is a proximity sensor that moves together with base portion 91, when protrusion member drive section 81b moves protrusion member 81a toward hole portion 64b1 to fit protrusion member 81a into hole portion 64b1 and is capable of detecting second member 92b that is closer in distance than first member 92a. Specifically, protrusion member drive section 81b moves protrusion member 81a toward hole portion 64b1 (step S21 illustrated in
[0082] When protrusion member 81a is not fitted into hole portion 64b1, biasing member 92c is contracted by the amount that protrusion member 81a cannot enter hole portion 64b1, and protrusion member 81a undergoes relative movement with respect to base portion 91. Accordingly, detection section 81c can detect the non-fitted state in which protrusion member 81a is not fitted into hole portion 64b1 by facing second member 92b and detecting second member 92b. When the non-fitted state is detected by detection section 81c (No in step S22), protrusion member drive section 81b rotates protrusion member 81a until the fitted state is detected by detection section 81c to change the rotation position (angle) of protrusion member 81a (step S24).
[0083] As described above, when protrusion member 81a is fitted into hole portion 64b1, detection section 81c detects the fitted state by facing first member 92a and not detecting second member 92b. Further, when protrusion member 81a is not fitted into hole portion 64b1, detection section 81c detects the not-fitted state by facing second member 92b due to relative movement and detecting second member 92b. Accordingly, protrusion member drive section 81b can reliably rotate manual sprocket 64b in a state where protrusion member 81a is fitted into hole portion 64b1.
1-3-2. Sensing Mechanism 82
[0084] Sensing mechanism 82 senses a pre-arrival state immediately before tip end portion 72t of carrier tape 72 reaches blade tip portion 66a of peeling blade 66. Sensing mechanism 82 need only be capable of sensing the pre-arrival state, and may take various configurations.
[0085] As illustrated in
[0086] As illustrated in
[0087] Sensing mechanism 82 may include a light projector capable of projecting light to carrier tape 72 at a predetermined position upstream of peeling blade 66 in the conveyance direction of carrier tape 72, and a light receiver that receives reflected light projected from the light projector and reflected by carrier tape 72. In this case, sensing mechanism 82 can determine the presence or absence of 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 higher than a predetermined level, sensing section 82b can also recognize the positional relationship in which tip end portion 72t of carrier tape 72 reaches blade tip portion 66a of peeling blade 66 and sense the pre-arrival state.
1-3-3. Positioning Mechanism 83 and Conveyance Section 84
[0088] When loading reel 70 into feeder 60, positioning mechanism 83 positions peeling blade 66 such that blade tip portion 66a of peeling blade 66 enters tip end portion 72t of carrier tape 72 before tip end portion 72t of carrier tape 72 reaches peeling blade 66 for peeling cover tape 72b. Positioning mechanism 83 need only be capable of positioning peeling blade 66 as described above, and may take various configurations. For example, positioning mechanism 83 of the embodiment includes pressing member 83a, pressing member drive section 83b, adjustment section 83c, and confirmation section 83d.
[0089] As illustrated in
[0090] The first end side of pressing member 83a is connected to pressing member drive section 83b. Pressing member drive section 83b moves the first end side of pressing member 83a upward in the vertical direction by, for example, a cylinder. Accordingly, pressing member 83a rotates around fulcrum 83a1. The second end side of pressing member 83a is formed in an L-shape, and the tip end portion can press predetermined portion 67b. Accordingly, the positioning of peeling blade 66 in the vertical direction is performed.
[0091] When the pre-arrival state is sensed by sensing mechanism 82 (Yes in step S25 illustrated in
[0092] Positioning mechanism 83 may include adjustment section 83c. Adjustment section 83c adjusts a pressure amount when pressing member 83a presses predetermined portion 67b (step S27). Adjustment section 83c need only be capable of adjusting the pressure amount, and may take various configurations. As illustrated in
[0093] Adjustment section 83c is formed in an elliptical shape when viewed in the direction of the rotation axis, and an amount of descent of pressing member 83a can be adjusted by the rotation position (angle). Pressing member 83a includes protruding portion 83a2 that protrudes downward. Protruding portion 83a2 descends by the amount of descent adjusted by adjustment section 83c, so that predetermined portion 67b of tape guide 67 can be pressed.
[0094] Positioning mechanism 83 may include confirmation section 83d. Confirmation section 83d confirms a peeled state in which cover tape 72b is peeled off by peeling blade 66 (step S28). Confirmation section 83d need only be capable of confirming the peeled state (the state in which cover tape 72b is appropriately peeled off), and may take various configurations. As illustrated in
[0095] When the peeled state is confirmed by confirmation section 83d (Yes in step S28), pressing member drive section 83b stops pressing of predetermined portion 67b by pressing member 83a (step S29). In addition, conveyance section 84 causes feeder 60 to convey carrier tape 72 until component 100 reaches collection position 63 where component 100 is collected (step S30). Specifically, conveyance section 84 rotates drive sprocket 64a to convey carrier tape 72.
[0096] For example, conveyance section 84 can use imaging device 82a described above to image collection position 63. Then, conveyance section 84 can perform image processing on image data of collection position 63 acquired by imaging device 82a and confirm the arrival of component 100. Conveyance section 84 can also confirm the arrival of component 100 using a height sensor provided at collection position 63. When the peeled state is not confirmed by confirmation section 83d (No in step S28), the pressing of predetermined portion 67b is continued until the peeled state is confirmed, and the rotation of manual sprocket 64b is continued.
1-3-4. Arrangement Example of Reel Loading Device 80
[0097] As illustrated in
[0098] In this case, operation mechanism 81 may be provided in non-operation area AR1 where the worker does not operate feeder 60. Similarly, moving section 82c of sensing mechanism 82 may be provided in non-operation area AR1. Pressing member drive section 83b of positioning mechanism 83 may be provided in non-operation area AR1. In either case, reel loading device 80 can be arranged in an area that does not affect the work of the worker.
[0099] Specifically, as illustrated in
[0100] The above description of non-operation area AR1 is particularly advantageous when feeder 60 is not covered by the housing and is exposed. For example, it is assumed that feeder 60 illustrated in
2. Example of Effects of Embodiment
[0101] With reel loading device 80, peeling blade 66 can be positioned such that blade tip portion 66a of peeling blade 66 enters tip end portion 72t of carrier tape 72 before tip end portion 72t of carrier tape 72 reaches peeling blade 66 for peeling cover tape 72b.
