Description

[Technical field]

[0001] This specification discloses a reel loader and a feeder preparation system. [Background technology]

[0002] Conventionally, a device has been proposed that automatically attaches and detaches a reel around which a tape containing parts is wound from a feeder. For example, Patent Document 1 describes a device that stores a reel removed from a feeder in a reel storage, and attaches a reel removed from a reel storage to a feeder. This allows reel replacement work to be performed without bothering an operator. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-197594 A Summary of the Invention [Problem to be solved by the invention]

[0004] Promoting automation of the reel replacement work described above is an important issue for increasing production efficiency. Here, since the number of feeders that can be fitted with reels is limited and feeders are often reused, it is necessary to first remove the reel that is attached to the feeder when installing a new reel. In this case, the tape must be properly disposed of when the removed reel is removed so that the efficiency is not reduced the next time the reel is automatically installed.

[0005] A primary object of the present disclosure is to more appropriately remove a reel in an automatic reel attachment / detachment device. [Means for solving the problem]

[0006] In order to achieve the above-mentioned main object, the present disclosure has adopted the following means.

[0007] The reel attachment / detachment device of the present disclosure is A reel attachment / detachment device that attaches and detaches a reel around which a tape containing components is wound to a feeder that feeds the components by driving a delivery section, the reel comprising: a feeder set unit in which the feeder is set so as to be capable of driving the delivery section; a reel transfer unit having a rotating part for rotating the reel around an axis and capable of transferring the reel by moving relatively to the feeder set unit; a holding portion capable of holding the tape of the reel attached to the feeder; A cutting portion capable of cutting the tape; a control device that executes removal control to control the feeder set unit and the reel transfer unit to drive the delivery unit and the rotating unit so that the tape is rewound and wound around the reel when the feeder to which the reel is attached is set in the feeder set unit, and then drive the holding unit and the cutting unit so that the tape is held and cut at the portion to which the components have been supplied, thereby removing the reel from the feeder; and The gist of the project is to provide the following:

[0008] In the reel attachment / detachment device of the present disclosure, the feeder is set in the feeder set unit so that the tape delivery section can be driven, so that the tape can be quickly rewound when the reel is removed. Also, the rotating section of the reel transfer unit allows the tape to be properly rewound onto the reel. Also, by rewinding the tape to the portion where components have already been supplied and cutting it, it is possible to prevent the components from being affected when the tip of the tape is processed when the next reel is attached. As a result, the reel can be more properly removed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, an embodiment for carrying out the present disclosure will be described with reference to the drawings. FIG. 1 is a schematic diagram of a component mounting system 1 according to the present embodiment. The component mounting system 1 includes a mounting line 10 for mounting components on a board, a preparation line 20 for preparing the supply of components, and a management device 2 for managing the entire system, which are installed in a factory or the like. The management device 2 is configured as a computer including a CPU, ROM, RAM, and HDD (not shown), and outputs mounting-related information and instructions to each device on the mounting line 10, and outputs preparation-related information and instructions to each device on the preparation line 20. In this embodiment, the left-right direction (X-axis), front-back direction (Y-axis), and up-down direction (Z-axis) are as shown in FIG. 1.

[0011] As shown in FIG. 1, the mounting line 10 includes a printing device 12 that prints solder on a board, a print inspection device 14 that inspects the state of the printed solder, and a mounting device 16 that mounts components on the board. The mounting devices 16 are arranged in a line along the board transport direction (X-axis direction), and multiple feeders 100 for supplying components can be attached to the front of the mounting devices 16. Each mounting device 16 is configured to pick up components supplied from the attached feeder 100 and mount them on the board. The mounting line 10 also includes a feeder storage area 18 installed between the mounting device 16 that is the most upstream in the board transport direction among the multiple mounting devices 16 and the print inspection device 14, and a loader 19 that moves in front of the multiple mounting devices 16 and in front of the feeder storage area 18 along the board transport direction. An AGV (automated guided vehicle) 4 or a worker stores the necessary feeders 100 in the feeder storage area 18 and collects unnecessary feeders 100 from the feeder storage area 18. Moreover, the loader 19 is configured to take out necessary feeders 100 from the feeder storage area 18 and supply them to the mounting devices 16, and to collect unnecessary feeders 100 from each mounting device 16 and return them to the feeder storage area 18. In addition to these, the mounting line 10 may also include a reflow device that performs a reflow process on the boards on which components are mounted.

[0012] 2 is a schematic diagram of the feeder 100. In the feeder 100, a reel 120 around which a tape 130 containing components is wound is detachably attached to a main body 101, and the feeder supplies the components by feeding out the tape 130. Note that a label 122 indicating the ID of the reel 120 and information on the type of components contained in the tape 130 is attached to the reel 120. The tape 130 is composed of a bottom tape 132 in which a plurality of cavities (recesses) are formed at predetermined intervals in the longitudinal direction and in which components are contained in each cavity, and a cover tape 134 attached so as to cover the surface of the bottom tape 132. Note that the tape 130 has engagement holes formed at equal intervals in the longitudinal direction.

[0013] The feeder 100 includes a main body 101, a tape feeding section 102, a tape guide 104, a reel cover 106, a connector 108, a positioning pin 109, a tape recovery section 110, and a control section (not shown).

[0014] The tape feed unit 102 includes a sprocket having a protrusion on its outer periphery that engages with an engagement hole in the tape 130, and a motor 103 (see FIG. 6) that drives the sprocket. With the tape 130 engaged with the sprocket, the tape feed unit 102 rotates the sprocket intermittently by forward rotation of the motor, thereby pitch-feeding the tape 130 toward the component supply position. The tape feed unit 102 can also rewind the tape 130 toward the reel 120 by reverse rotation of the motor. The tape guide 104 is provided on the upper part of the main body 101, and guides the cover tape 134 peeled off from the tape 130 so that it turns back toward the tape recovery unit 110, and also guides the bottom tape from which the cover tape 134 has been peeled off to the component supply position. The tape guide 104 is configured to be slightly movable up and down (opening and closing) relative to the main body 101. The reel cover 106 is provided at the lower edge of the main body 101 so as to be openable and closable, and when closed, covers the reel 120 to prevent it from falling off, and when open (as shown in FIG. 2), exposes the reel 120 so that it can be detached. The connector 108 and the positioning pin 109 are provided so as to protrude from the end face of the main body 101. Although not shown, the feeder table such as the mounting device 16 and the feeder storage area 18 is provided with a connector to which the connector 108 can be connected and a pin hole to which the positioning pin 109 can be engaged. Therefore, when the feeder 100 is attached to the feeder table, the connector 108 is connected to the connector of the feeder table and the positioning pin 109 is engaged with the pin hole. A control unit (not shown) of the feeder 100 can communicate with a control unit of the mounting device 16 and the like through the connection of the connector, and controls the tape feed unit 102 to pitch-feed the tape 130 upon receiving a component supply instruction.

[0015] The tape recovery unit 110 recovers the cover tape 134 peeled off from the tape 130, and as an example, a type (first type) in which the cover tape 134 is recovered while being wound using a recovery drum 115 is shown. The tape recovery unit 110 includes a drum shaft 111 to which the annular recovery drum 115 is detachably attached and which is rotated by a motor (not shown), and a plurality of guide pins 113 that form a guide path for guiding the cover tape 134 folded back by the tape guide 104 to the recovery drum 115. FIG. 3 is a schematic diagram of the recovery drum 115, and the recovery drum 115 includes a connection tape 116 extending from an annular drum main body 115a. The connection tape 116 includes a fixed piece 117 fixed to a tip, a U-shaped loop 118 having both base ends attached to the end faces of the fixed piece 117, and a slide piece 119 attached slidably along the extension direction of the loop 118 (the direction of the arrow in FIG. 3). As described below, the sliding of the slide piece 119 connects the loop 118 of the connection tape 116 with the cover tape 134. The tape recovery unit 110 rotates the drum shaft 111, to which the recovery drum 115 is attached, by driving a motor, thereby winding up and recovering the cover tape 134 together with the connection tape 116. Note that there is another type (second type) in which, for example, a pair of gears rotate holding the cover tape 134 in between, thereby recovering the cover tape 134 while pulling it in, but this is a well-known configuration and will not be described here.

[0016] As shown in Figs. 1 and 4, the preparation line 20 includes an automatic reel storage 22, a reel transfer robot 24, a reel storage area 25, a feeder storage 26, a feeder storage area 28, a loader 29, and a reel mounting / removal device 30. The automatic reel storage 22 is configured to automatically store the reel 120 placed on a receiving platform 22a provided in the front and store it in the storage, and to automatically take out a necessary reel 120 from the storage and place it on the receiving platform 22a. The reel transfer robot 24 includes a vertical articulated robot arm. The reel transfer robot 24 transfers the reel 120 placed in the reel storage area 25 by an operator to the receiving platform 22a of the automatic reel storage 22, and transfers the reel 120 dispensed to the receiving platform 22a into the reel mounting / removal device 30. The AGV 4 or a worker returns the feeder 100 collected from the mounting line 10 to the feeder storage area 28, or takes out a necessary feeder 100 from the feeder storage area 28 and stores it in the feeder storage area 18 of the mounting line 10. The loader 29 moves in front of the multiple feeder storage cabinets 26 and in front of the feeder storage areas 28, and takes out the feeder 100 from the feeder storage areas 28 and stores it in the feeder storage cabinet 26, or takes out the feeder 100 from the feeder storage cabinet 26 and stores it in the feeder storage area 28. The loader 29 also transfers the feeder 100 to be detached from the reel 120 into the reel attachment / detachment device 30. Note that FIG. 1 illustrates two reel storage areas 25: a storage area for used (out-of-parts) reels 120 and a storage area for new reels 120.

[0017] The reel mounting / removing device 30 comprises a reel set table 35, a control device 39, a feeder set unit 40, a cover opening / closing unit 50, a reel transfer unit 60, a drum set unit 70, and a tape cutting unit 90, which are mounted on a base 31.

[0018] 5, the reel setting table 35 includes a base 36 and a support pin 37. The base 36 is a flat plate-like member fixed to stand vertically on the upper plate 32 of the base 31. The support pin 37 is an axial member that stands vertically from the plate surface of the base 36 on the right side in the figure and can be inserted into a central hole of the reel 120. The reel 120 is detachably set on the reel setting table 35 by the reel transfer robot 24 or the reel transfer unit 60 such that the support pin 37 is inserted into the central hole of the reel 120.

[0019] In the feeder set unit 40, the feeder 100 to which the reel 120 is to be attached or detached is transferred by the loader 29 to the base 40a fixed to the upper plate 32 of the base 31. The base 40a is provided with a connector to which the connector 108 of the feeder 100 can be connected and a pin hole to which the positioning pin 109 can be engaged, similar to the feeder table of the mounting device 16 and the like. Therefore, the control device 39 can communicate with the control unit of the feeder 100 attached to the feeder set unit 40 via the connection of the connector, and control the tape feeding unit 102.

[0020] As shown in FIG. 6, the feeder set unit 40 includes a guide opening / closing section 42, a tape drawing section 44, and a tape connection section 46. Although not shown, the guide opening / closing section 42 includes a clamp for clamping the tape guide 104 from the left and right, an opening / closing cylinder for opening and closing the clamp, and an elevation cylinder for raising and lowering the clamp, and the clamp clamps the tape guide 104 from the left and right and raises and lowers it up and down. The tape drawing section 44 includes a clip for gripping the tip of the cover tape 134 of the reel 120 attached to the feeder 100, a moving section for moving the clip, and an actuator for opening and closing the clip via a wire connected to the clip. The tape drawing section 44 inserts the clip into the tape guide 104 with the tape guide 104 positioned at the top by the guide opening / closing section 42, grips the tip of the cover tape 134, and withdraws the clip, thereby drawing out the cover tape 134.

[0021] FIG. 7 is a schematic diagram of the tape splicing section 46. The tape splicing section 46 includes a fixed clamp section 47, a movable clamp section 48, and a slide section 49. The fixed clamp section 47 includes a pair of clamp members 47a, 47b that clamp the fixed piece 117 of the splicing tape 116, and a clamp cylinder 47c that clamps and releases the clamp by raising and lowering the clamp member 47a. The movable clamp section 48 includes a pair of clamp members 48a, 48b that clamp the slide piece 119 of the splicing tape 116, and a clamp cylinder 48c that clamps and releases the clamp by raising and lowering the clamp member 48a. The slide section 49 includes a slide block 49a connected to the clamp cylinder 48c of the movable clamp section 48, and a slide cylinder 49b that slides the movable clamp section 48 together with the slide block 49a. As shown in Fig. 7A, the tape connection section 46 is in a state where the fixed clamp section 47 clamps the fixed piece 117 and the movable clamp section 48 clamps the slide piece 119. In this state, the feeder set unit 40 inserts the tip of the cover tape 134 pulled out by the tape pull-out section 44 into the loop 118. Then, as shown in Fig. 7B, the tape connection section 46 moves the movable clamp section 48 toward the tip of the loop 118 by operating the slide cylinder 49b to contract the loop 118, thereby connecting the cover tape 134 to the loop 118 so that the cover tape 134 does not come off. In this way, the connection tape 116 and the cover tape 134 are connected (see Fig. 8).

[0022] As shown in FIG. 9, the cover opening / closing unit 50 includes a base 50a, a support 52, a rotating plate 53, a suction pad 54, a motor 55, and a pulley 56. Here, an opening 32a (see FIG. 4) is formed in the upper plate 32 of the base 31 on the front side (right side) of the feeder set unit 40. The cover opening / closing unit 50 is disposed below the upper plate 32 by fixing four support columns 52 erected at the four corners of the rectangular flat base 50a to the edges of the opening 32a. The rotating plate 53 is formed in a substantially T-shape, and the base end is rotatably supported by the base 50a, and the suction pads 54 are attached to both ends of the tip end. The motor 55 is attached to the base 50a, and transmits a driving force via the pulley 56 to rotate the rotating plate 53. The suction pad 54 is connected to a negative pressure source such as a vacuum pump via a tube, and switches between suction and non-suction depending on whether the vacuum pump is activated or not. When the cover opening / closing unit 50 rotates the rotating plate 53 by the forward rotation of the motor 55 until it is approximately perpendicular to the base 50a, the suction cup 54 comes into contact with the reel cover 106 of the feeder 100. In this state, the cover opening / closing unit 50 operates the vacuum pump to cause the suction cup 54 to suck the reel cover 106, and then rotates the motor 55 in the reverse direction to rotate the rotating plate 53, thereby opening the reel cover 106 so as to fit it within the opening 32a.

[0023] As shown in Fig. 10, the reel transfer unit 60 includes a slide base 60a, a support pin 61, an expanding cylinder 61a, a motor 62, a push plate 63, a push cylinder 63a, a chuck 64, a chuck cylinder 64a, a guide pin 65, a cutter 66, and a cutter cylinder 66a. The slide base 60a is slidable in the X-axis direction and the Y-axis direction by a slide unit 33 disposed on the upper plate 32. The slide unit 33 is a well-known configuration including a slide rail laid in the sliding direction and a slider that slides along the slide rail by driving an actuator such as a motor. The support pin 61 is, for example, a pin formed into a cylindrical shape by combining two semi-cylindrical members having a semicircular cross section, and can be inserted into the center hole of the reel 120 in a cylindrical state. In addition, when the two semi-cylindrical members move away from each other by the operation of the diameter-enlarging cylinder 61a and the outer diameter is enlarged, the support pin 61 fits into the center hole of the reel 120 to hold the reel 120 so as not to fall off. The driving force of the motor 62 is transmitted to the support pin 61 via a pulley (not shown) to rotate around the axis. The push-in plate 63 is a flat plate member formed to cut out the placement portion of the support pin 61, and moves along the extension direction of the support pin 61 by the operation of the push-in cylinder 63a to push the reel 120 into the feeder 100 or the like and attach it. The chuck 64 holds the tip of the tape 130 of the reel 120 by the operation of the chuck cylinder 64a. The guide pin 65 guides the tip of the tape 130 of the reel 120 so that it faces the chuck 64 side. The cutter 66 cuts the tip of the tape 130 by the operation of the cutter cylinder 66a.

[0024] The reel transfer unit 60 is configured such that the push-turning plate 67 shown in FIG. 11 can be attached to and detached from the support pin 61. The push-turning plate 67 is a disk-shaped member used when pushing and turning the reel 120, into whose center hole the cylindrical support pin 61 can be inserted, and a plurality of buffer members 68 are provided on the surface of the plate. The buffer member 68 is a rectangular parallelepiped member formed of, for example, urethane rubber or sponge, and is provided so that its longitudinal direction extends in the radial direction. When the outer diameter of the support pin 61 is expanded by the operation of the diameter expansion cylinder 61a, the support pin 61 fits into the center hole of the push-turning plate 67 and can rotate integrally with the push-turning plate 67. Although not shown, a place for the push-turning plate 67 is provided at a predetermined position on the upper plate 32, and the reel transfer unit 60 can move to the place to attach the push-turning plate 67 to the support pin 61 or remove the push-turning plate 67 from the support pin 61.

[0025] As shown in Fig. 5 and Fig. 12, the drum set unit 70 includes a fixed unit 71 having a fixed base 71a fixed to stand on the upper plate 32, and a moving unit 81 having a slide base 81a slidable in the X-axis direction and the Y-axis direction by a slide unit 34 arranged on the upper plate 32. As shown in Fig. 13, the fixed unit 71 includes a Y-axis slider 72, a motor 73 (see Fig. 6), a pulley 74, a Z-axis slider 75, a motor 76, a pulley 77, a chuck 78, and a chuck cylinder 78a. The Y-axis slider 72 moves along the Y-axis direction (front-back direction) on the front surface of the fixed base 71a (right surface in Fig. 13) by transmitting the driving force of the motor 73 arranged on the back surface of the fixed base 71a (left surface in Fig. 13) via the pulley 74. Z-axis slider 75 is provided on Y-axis slider 72, and moves in the Z-axis direction (up and down) along the front surface of Y-axis slider 72 as the driving force of motor 76 is transmitted via pulley 77. Chuck 78 is provided on Z-axis slider 75, and holds connecting tape 116 on collection drum 115 by operation of chuck cylinder 78a.

[0026] As shown in Fig. 12 and Fig. 14, the moving unit 81 includes a rotating transfer table 82, a motor 83, a drum chuck 84, a chuck cylinder 84a (see Fig. 6), a guide pin 85, a pin cylinder 85a (see Fig. 6), a tape chuck 86, a chuck cylinder 86a, a motor 87, and a pulley 88. The rotating transfer table 82 is a disk-shaped member having a support shaft 82a to which the drum body 115a of the collection drum 115 is detachably attached, and is capable of rotating the drum body 115a by being rotated by the drive of the motor 83. The rotating transfer table 82 is also formed with a plurality of (for example, three) elongated holes 82b extending in the radial direction at equal intervals in the circumferential direction. The drum chuck 84 has a plurality of (three) chuck claws that move in the elongated hole 82b by the operation of the chuck cylinder 84a, and each chuck claw opens and closes by the operation of the chuck cylinder 84a to grip and release the collection drum 115. A plurality of guide pins 85 are provided so as to stand from the left side surface of the moving unit 81 toward the fixed unit 71. The plurality of guide pins 85 are provided at positions corresponding to at least the guide pins 113 so as to be able to form a path similar to the guide path that guides the cover tape 134 to the collection drum 115 in the feeder 100. Therefore, the drum set unit 70 can guide the connection tape 116 to crawl on the guide pins 85 by moving the chuck 78 holding the tip of the connection tape 116 along the path formed by the guide pins 85 by the Y-axis slider 72 and the Z-axis slider 75, thereby forming a path similar to the guide path in the feeder 100. Further, some of the guide pins 85 are moved by driving the pin cylinder 85a, so that the guide pins 85 can hold the connecting tape 116. The tape chuck 86 can hold the leading end of the connecting tape 116 that has formed a guide path by operating the chuck cylinder 86a, and the driving force of the motor 87 is transmitted via a pulley 88 to move in the Y-axis direction, so that the position of the leading end of the held connecting tape 116 can be adjusted.

[0027] 15 and 16, the tape cutting unit 90 includes a base 90a, a cutting table 91, a tape feed section 92, a first tape cutter 95, a second tape cutter 96, a third tape cutter 97, and a slider 98. The tape feed section 92 includes a sprocket 93 having a protrusion on its outer periphery that engages with an engagement hole in the tape 130, and a motor 94 that drives the sprocket 93. With the tape 130 fed from the reel 120 of the reel transfer unit 60 with reference to the right end of the cutting table 91 engaged with the sprocket 93, the tape feed section 92 rotates the sprocket 93 by forward rotation of the motor 94 to feed the tape 130 toward the cutting position.

[0028] The first tape cutter 95 has a scissors-shaped cutting blade arranged in a direction perpendicular to the feed direction of the tape 130, and is actuated by driving the cutter cylinder 95a to cut the tape 130. The second tape cutter 96 has a cutting blade arranged diagonally to the feed direction of the tape 130, and cuts the right side of the leading edge of the tape 130 in a tapered shape by driving the cutter cylinder 96a. The third tape cutter 97 has a cutting blade arranged diagonally to the feed direction of the tape 130, and cuts the left side of the leading edge of the tape 130 in a tapered shape by driving the cutter cylinder 97a. The third tape cutter 97 is provided on a slider 98 that slides in the X-axis direction (left-right direction) above the cutting table 91, and is movable left and right. Therefore, the tape cutting unit 90 can cut the left side of the leading edge of the tape 130, which is fed based on the right end of the cutting table 91, in a tapered shape by adjusting the position of the third tape cutter 97 according to the width of the tape 130. It should be noted that by cutting the leading end of tape 130 (cover tape 134) into a tapered shape, the leading end can be inserted smoothly into loop 118 without getting caught (see FIG. 7).

[0029] The control device 39 includes a CPU 39a, a ROM 39b, a RAM 39c, and the like. Status information and the like are input to the control device 39 from each unit of the reel mounting / removal device 30, and status information of the reel transfer robot 24 and the loader 29 and instructions for mounting / removing the reel 120 are input from the management device 2. The control device 39 outputs a control signal to each unit of the reel mounting / removal device 30 based on the information and the mounting / removal instructions, and performs mounting / removal of the reel 120 to / from the feeder 100 set in the feeder set unit 40. In addition to these components, the reel mounting / removal device 30 may include a camera capable of capturing an image of the label 122 of the reel 120 attached to the feeder 100. In addition, the reel mounting / removal device 30 may include a temporary fixing unit that fixes the tape 130 with a temporary fixing tape when removing the reel 120 from the feeder 100 set in the feeder set unit 40, and may include a peeling unit that peels off the temporary fixing tape when attaching the reel 120.

[0030] The operation of the reel mounting / removing device 30 thus configured will be described below. FIG. 17 is a flow chart showing an example of a reel removal process. This process is executed by the control device 39 when the feeder 100 from which the reel 120 is to be removed is set in the feeder set unit 40. First, the control device 39 controls the cover opening / closing unit 50 to open the reel cover 106 (S100). As described above, the cover opening / closing unit 50 holds the reel cover 106 in the opening 32a, so that the open reel cover 106 does not interfere with the movement or work of other units. Next, the control device 39 controls the slide unit 33 to move the reel transfer unit 60 to the feeder set unit 40 (S105). Note that the reel transfer unit 60 is in a state in which the push-rotating plate 67 is attached to the support pin 61. Next, the control device 39 controls the feeder 100 and the reel transfer unit 60 set in the feeder set unit 40 so as to secure a predetermined length and rewind the tape 130 (S110). In S110, the control device 39 controls the tape feed section 102 of the feeder 100 to rotate in the reverse direction, and controls the reel transfer unit 60 so as to push and turn the reel 120 in the reverse direction with the push-turning plate 67. After S110 is completed, the control device 39 controls the reel transfer unit 60 to remove the push-turning plate 67 from the support pin 61.

[0031] Here, in the first type feeder 100 using the collection drum 115, the tip of the cover tape 134 is connected to the connection tape 116 when the reel 120 is next attached (see FIG. 8), so the length of the tape 130 (cover tape 134) that needs to be secured when removing the reel 120 can be short. On the other hand, in the second type feeder 100 using the winding gear, etc., it is necessary to secure the length required for the cover tape 134 to reach the winding gear when the reel 120 is next attached. In this embodiment, in order to be able to handle whatever type of feeder 100 the reel 120 is attached to next, a predetermined length is secured in S110 according to the type that requires the most length (here, the second type).

[0032] When the tape 130 is rewound, the control device 39 controls the reel transfer unit 60 to cut the tape 130 and remove the reel 120 from the feeder 100 (S115). The reel transfer unit 60 causes the cutter 66 to enter the feeder 100 to cut the tape 130. Next, the control device 39 controls the slide unit 33 to move the reel transfer unit 60 to the reel set table 35 (S120), and controls the reel transfer unit 60 to set the removed reel 120 on the reel set table 35 (S125). If there are any remaining parts on the tape 130, the reel 120 set on the reel set table 35 is transferred to the receiving table 22a of the automatic reel storage 22 by the reel transfer robot 24. Furthermore, reels 120 with no remaining parts are transferred to a used reel storage area 25 by a reel transfer robot 24, or are discharged from a discharge port (not shown) formed in the upper plate 32.

[0033] Next, the control device 39 judges whether the feeder 100 is a first type using the collection drum 115 (S130). If the control device 39 judges that the feeder 100 is the first type, the control device 39 controls the slide unit 34 so that the moving unit 81 of the drum set unit 70 moves to the feeder set unit 40 (S135). Next, the control device 39 controls the drum chuck 84 of the moving unit 81 so as to remove the collection drum 115 from the feeder 100 (S140). Then, the control device 39 controls the slide unit 34 so that the moving unit 81 moves to a standby position such as in front of the fixed unit 71 (S145). If the control device 39 judges that the feeder 100 is not the first type in S130, it skips S135 to S145. The collection drum 115 removed in S140 is collected in a dust box or the like from a discharge port (not shown) formed in the upper plate 32 until the moving unit 81 moves to the standby position. In addition, the worker may remove and discard the cover tape 134 from the collection drum 115 collected in the dust box, and the moving unit 81 of the drum set unit 70 may set the collection drum 115 in a predetermined location where it can be received.

[0034] Then, the control device 39 judges whether or not the reel 120 is to be attached to the feeder 100 set in the feeder set unit 40 (S150). If the control device 39 judges that the reel 120 is not to be attached, it controls the cover opening / closing unit 50 to close the reel cover 106 (S155) and ends the reel removal process. On the other hand, if the control device 39 judges that the reel 120 is to be attached, it skips S155 and ends the reel removal process with the reel cover 106 left open.

[0035] Next, the reel mounting process will be described. FIG. 18 is a flow chart showing an example of the reel mounting process. This process is executed by the control device 39 when the feeder 100 to which the reel 120 is to be mounted is set in the feeder set unit 40, for example, when the reel removal process in FIG. 17 is ended with the reel cover 106 open. First, the control device 39 controls the slide unit 33 so that the reel transfer unit 60 moves to the reel set table 35 (S200). Note that the reel transfer unit 60 is in a state in which the push-rotating plate 67 is removed from the support pin 61. Next, the control device 39 controls the reel transfer unit 60 so that it receives the reel 120 set on the reel set table 35 (S205). Next, the control device 39 controls the slide unit 33 so that the reel transfer unit 60 moves to the tape cutting unit 90 (S210). Then, the control unit 39 controls the reel transfer unit 60 and the tape cutting unit 90 so as to feed out a required amount of the tape 130 from the reel 120 and cut the leading end of the tape 130 into a required shape (S215). If the feeder 100 to be attached is the first type using the recovery drum 115, the control unit 39 controls the tape cutting unit 90 so as to cut the leading end of the tape 130 into a tapered shape so as to facilitate insertion into the loop 118 as described above. If such tapered cutting is not required, the control unit 39 controls the tape cutting unit 90 so as to cut only in a direction perpendicular to the longitudinal direction of the tape 130, for example. Note that the leading ends of all the tapes 130 may be cut into a tapered shape. When the tape cutting unit 90 cuts the tape 130, the control unit 39 controls the reel transfer unit 60 so as to rewind the tape 130 and hold the leading end of the tape 130 by the chuck 64.

[0036] Next, the control device 39 controls the slide unit 33 so that the reel transfer unit 60 moves to the feeder set unit 40 (S220). If the reel cover 106 of the feeder 100 set in the feeder set unit 40 is closed, the control device 39 controls the cover opening / closing unit 50 so as to open the reel cover 106 prior to S220. Next, the control device 39 controls the reel transfer unit 60 and the slide unit 33 so that the reel 120 is attached to the feeder 100 set in the feeder set unit 40 and the feeder 100 moves to a predetermined standby position (S225).

[0037] Then, the control device 39 judges whether the feeder 100 is a first type that requires the collection drum 115 (S230). If the control device 39 judges that the feeder 100 is the first type, the control device 39 controls the drum set unit 70 to make the connection tape 116 run along the path formed by the guide pins 85, hold the connection tape 116 between the guide pins 85, and hold the tip of the connection tape 116 by gripping it with the tape chuck 86 (S235). Next, the control device 39 controls the slide unit 34 to make the moving unit 81 move to the feeder set unit 40 (S240). Next, the control device 39 controls the drum set unit 70 to attach the collection drum 115 and the connection tape 116 to the feeder 100 of the feeder set unit 40 (S245). The control device 39 attaches the connection tape 116, which has been laid along the path formed by the guide pins 85, so as to pass it over each guide pin 113 of the feeder 100 as is, and then controls the drum set unit 70 to release the holding of the connection tape 116 by the guide pins 85. This allows the connection tape 116 to be attached so as to follow the guide path of the feeder 100. Furthermore, if the control device 39 determines in S230 that the recovery drum 115 is not required, it skips S235 to S245. The control device 39 may execute S235 to S245 prior to S200 to S215, or may execute S200 to S215 in parallel.

[0038] Then, the control device 39 controls the feeder set unit 40 to perform the leading end processing of the tape 130 (S250). For example, if the feeder 100 is the first type, the control device 39 controls the feeder set unit 40 to pull out the cover tape 134 and connect it to the connection tape 116. If the feeder 100 is the second type, the control device 39 controls the feeder set unit 40 to pull out the cover tape 134 and send it to the guide path. After the reel 120 is thus attached, the control device 39 controls the cover opening / closing unit 50 to close the reel cover 106 (S255), and ends the reel attachment process. Note that, if the reel attachment / detachment device 30 is equipped with a camera capable of capturing an image of the label 122 of the reel 120, the control device 39 may cause the camera to capture an image of the label 122 before closing the reel cover 106, and may recognize information about the label 122 by processing the captured image. Based on the recognized information, the control device 39 can confirm whether the correct reel 120 has been attached, register it in correspondence with the feeder 100, and transmit the recognized information to the management device 2 along with a notification that the attachment of the reel 120 has been completed.

[0039] Here, the correspondence between the components of this embodiment and the components of this disclosure will be clarified. The reel mounting / removal device 30 of this embodiment corresponds to the reel mounting / removal device of this disclosure, the feeder set unit 40 corresponds to the feeder set unit, the reel transfer unit 60 corresponds to the reel transfer unit, the chuck 64 corresponds to the holding unit, the cutter 66 corresponds to the cutting unit, and the control device 39 corresponds to the control device. The recovery drum 115 corresponds to the drum-shaped recovery unit. The guide pin 85 corresponds to the path forming unit, the chuck 78, the Y-axis slider 72, and the Z-axis slider 75 correspond to the guiding unit, the drum set unit 70 corresponds to the recovery unit set unit, and the tape connection unit 46 corresponds to the connection unit. The reel cover 106 corresponds to the opening / closing cover, and the cover opening / closing unit 50 corresponds to the cover opening / closing unit. Furthermore, the preparation line 20 corresponds to a feeder preparation system, the feeder storage 26 corresponds to a feeder storage section, the loader 29 corresponds to a feeder preparation device, the reel set table 35 corresponds to a reel set table, and the reel transfer robot 24 corresponds to a reel preparation device.

[0040] In the reel mounting / removing device 30 described above, the feeder 100 is set in the feeder set unit 40 so that the tape feed section 102 (sending section) can be driven, so that the tape 130 can be quickly rewound when the reel 120 is removed. Also, the reel transfer unit 60 rotates the push-turning plate 67, so that the tape 130 can be appropriately rewound onto the reel 120. Also, by rewinding the tape 130 to the portion where components have already been supplied and cutting it, it is possible to prevent components from falling off during the end processing of the tape 130 when the reel 120 is next attached. As a result, the reel 120 can be more appropriately removed.

[0041] In addition, since the tape 130 (cover tape 134) is rewound so as to secure a predetermined length, the time required for the process of recovering the cover tape 134 when the reel 120 is next attached can be suppressed. In addition, since the drum set unit 70 attaches the connection tape 116 to the feeder 100 after aligning it along the guide path of the cover tape 134, the recovery drum 115 can be attached efficiently. In addition, since the reel attachment / detachment device 30 performs the removal and attachment of the reel 120 with a common device, it can be configured more compactly than when separate devices are used for the removal and attachment. In addition, since the cover opening / closing unit 50 holds the reel cover 106 in the open state at a position that does not interfere with the movement of other units, the removal and attachment of the reel can be performed more efficiently.

[0042] It goes without saying that the present disclosure is in no way limited to the above-described embodiment, and can be embodied in various forms as long as it falls within the technical scope of the present disclosure.

[0043] For example, in the above-described embodiment, when the reel 120 is removed, the tape 130 is rewound to ensure a predetermined length, but this is not limited to this. For example, the next time the reel 120 is attached, an extension tape of the required length may be added to the end of the tape 130.

[0044] In the above-described embodiment, both the chuck 64 and the cutter 66 are provided in the reel transfer unit 60, but this is not limited to the above, and either one or both may be provided in a location other than the reel transfer unit 60, for example, in the feeder set unit 40.

[0045] In the above-described embodiment, the first type feeder 100 that collects the tape by the collection drum 115 is exemplified, and the drum set unit 70 that attaches and detaches the collection drum 115 and forms a path for the connection tape 116 is provided, but the present invention is not limited to this. For example, the reel transfer unit 60 may remove the collection drum 115 together with the reel 120, instead of the drum set unit 70. Also, the feeder set unit 40 or the reel transfer unit 60 may form a path for the connection tape 116 after the collection drum 115 is attached to the feeder 100. In such a case or when the first type feeder 100 is not handled, the drum set unit 70 may not be provided.

[0046] In the above-described embodiment, the reel cover 106 is attached to the lower edge of the feeder 100 so as to be openable and closable, but this is not limited thereto, and it is sufficient that the reel cover 106 is attached to the feeder 100 so as to be openable and closable, and the opening and closing direction may be the left-right direction.

[0047] In the above embodiment, the feeder 100 is set so that the feeder set unit 40 can drive the tape feed section 102, but the present invention is not limited to this, and the feeder 100 may be set so that the tape feed section 102 cannot be driven. In addition, the reel transfer unit 60 uses the push-turning plate 67 to push the reel 120, but the reel 120 may be rotated by a method other than pushing it. Alternatively, the reel transfer unit 60 may not rotate the reel 120 (does not have a rotating section). In addition, the control device 39 may drive the chuck 64 (holding section) and the cutter 66 (cutting section) so as to hold and cut the tape 130 at the part to which the components have been supplied, at least when the feeder 100 to which the reel 120 is attached is set in the feeder set unit 40.

[0048] In the above-described embodiment, the preparation line 20 (preparation system) including the loader 29 for setting the feeder 100 in the feeder set unit 40 and the reel transfer robot 24 for setting the reel 120 in the reel set table 35 in addition to the reel mounting / detaching device 30 has been exemplified, but is not limited thereto. The reel mounting / detaching device 30 may be disposed independently, and the setting of the feeder 100 and the setting of the reel 120 may be performed by another device such as an AGV or by an operator. The arrangement of each unit of the reel mounting / detaching device 30 and the function of each unit are merely examples, and it is sufficient that the reel mounting / detaching device 30 as a whole is configured to automatically mount and detach the reel 120 on the feeder 100.

[0049] Here, the reel attachment / detachment device of the present disclosure may be configured as follows. In the reel attachment / detachment device of the present disclosure, the tape has a bottom tape that houses the component and a cover tape that covers the component, and the component can be supplied by peeling off the cover tape. The feeder includes a type having a drum-shaped recovery section that recovers the cover tape while winding it together with a connection tape whose tip is connected to the cover tape, and a type that draws the cover tape to a recovery section different from the drum shape and recovers it. In the removal control, the control device may drive the drive section and the rotation section so that the cover tape is rewound while securing a length that can be used for either type when the reel is next attached to the feeder. In this way, the reel can be appropriately removed in consideration of the case where the reel is next attached. Therefore, the time required for the process of recovering the cover tape when the reel is next attached can be suppressed, and the automatic attachment of the reel can be efficiently performed.

[0050] In the reel attachment / detachment device of the present disclosure, the feeder is provided with a guide path for guiding the cover tape to the collection section, is configured to be movable relative to the feeder set unit, has a path forming section for forming a path along the guide path, and a guide section for guiding the connection tape so as to make it crawl along the path forming section, and is provided with a collection section set unit capable of transferring the drum-shaped collection section, the feeder set unit has a connection section for connecting an end of the connection tape and an end of the peeled cover tape, and the control device may control the collection section set unit to attach the connection tape and the collection section to the feeder set in the feeder set unit after the connection tape is made to crawl along the path forming section in advance by the collection section set unit, and control the feeder set unit to connect the end of the connection tape and the end of the cover tape by the connection section. In this way, the reel and the collection section can be efficiently attached in a feeder that uses a drum-shaped collection section.

[0051] In the reel mounting / removing device of the present disclosure, the control device may execute mounting control to control the feeder set unit and the reel transfer unit so as to mount the reel on the feeder with the feeder from which the reel has been removed set in the feeder set unit, drive the holding section and the rotating section so that the leading end of the tape is sent out from the reel to the delivery section, and drive the delivery section until the leading end of the tape reaches a predetermined position. In this way, the reel can be removed and mounted by a common mounting / removing device, making it possible to configure the mounting / removing device compact.

[0052] In the reel attachment / detachment device of the present disclosure, the feeder may have an openable cover that exposes the reel in an open state so as to be detachable, and may further include a cover opening / closing unit that is configured to be able to open and close the openable cover of the feeder set in the feeder set unit and that holds the openable cover in a position that does not interfere with the relative movement of other units with respect to the feeder set unit. In this way, the reel can be attached and detached more efficiently.

[0053] Another reel mounting / removal device disclosed herein is a reel mounting / removal device that mounts / removes a reel on which a tape is wound to / from a feeder that supplies the components by driving a tape containing the components and feeding the tape by driving a delivery unit, and includes a feeder set unit in which the feeder is set, a holding unit capable of holding the tape of the reel mounted on the feeder, a cutting unit capable of cutting the tape, and a control device that drives the holding unit and the cutting unit to hold and cut the tape at the portion where the components have been supplied, when the feeder to which the reel is attached is set in the feeder set unit. Even in this way, by cutting the tape at the portion where the components have been supplied, it is possible to prevent the components from being affected by the end processing of the tape when the next reel is attached, and therefore it is possible to more appropriately remove the reel in a device that automatically mounts / removes the reel.

[0054] The feeder preparation system of the present disclosure comprises any one of the reel attachment / detachment devices described above, a feeder preparation device capable of transferring the feeders between a feeder storage section that stores a plurality of the feeders and the feeder set unit, and preparing the feeder to be attached / detached to / from the reel, a reel set table on which the reel is set so that the reel transfer unit can transfer it, and a reel preparation device capable of transferring the reel between a reel storage section that stores a plurality of the reels and the reel set table, and preparing the reel to be attached / detached to / from the feeder.

[0055] The feeder preparation system of the present disclosure can more appropriately remove the reel since the reel is automatically attached to and detached from the feeder by any of the reel attachment / detachment devices described above. In addition, the feeder preparation and the reel preparation can be performed automatically, so that the automatic attachment / detachment of the reel can be performed more efficiently.
