  Above the substrate transfer device 12, a moving table 18 of the component transfer device 17 is mounted on an elongated slide 16 so as to be movable in the X direction, and the slide 16 is attached to a fixed rail 19 extending in the Y direction perpendicular to the X direction. It is supported so as to be movable in the Y direction. The movement of the moving table 18 and the slide 16 in the X and Y directions is controlled by a servo motor via a ball screw.

  The component transfer device 17 includes a component mounting head 20 that is mounted on a movable table 18 so as to be movable up and down in the Z direction perpendicular to the Y direction and the X direction, and whose elevation is controlled by a servo motor via a ball screw. A cylindrical suction nozzle 21 that protrudes downward from the mounting head 20 and holds an electronic component at the lower end is provided.

  A substrate recognition camera 28 is juxtaposed with the suction nozzle 21 on the movable table 18, and the substrate recognition camera 28 images the substrate B positioned and held on the substrate transport device 12 and transmits image information to the control device 40. The control device 40 corrects the mounting position of the component P on the board B according to the positioning error of the board B based on the image information taken by the board recognition camera 28. The component transfer device 17 sucks the component P supplied to the component supply position 30 by the suction nozzle 21 provided on the component supply device 10 side from the substrate recognition camera 28 and is positioned and held by the substrate transport device 12. It is transported to the mounting position on B and mounted.

  In the electronic component mounting apparatus 11, a component supply apparatus 10 including a plurality of tape feeders 22 is attached to the base 13 on the rear side in the Y direction from the substrate transport apparatus 12. Feeder mounting position identification codes S1 to Sn are attached to the feeder mounting positions 23 to which the tape feeders 22 of the component supply apparatus 10 are mounted, and the feeder identification codes F1 to Fn unique to each feeder are assigned to each tape feeder 22. It is attached.

  As shown in FIG. 2, the tape feeder 22 is provided with a main body 24, a reel mounting portion 26 provided at a rear portion of the main body 24, on which a reel 25 is rotatable and detachably mounted, and mounted on the reel mounting portion 26. A component transfer device 29 is provided for transferring the component P to the component supply position 30 one by one by feeding the component tape 27 holding the plurality of components P from the reel 25 one pitch at a time. The component transfer device 29 includes a guide portion 31 that guides the component tape 27 to a component supply position 30 provided at the distal end portion of the main body 24, and is rotatably supported at the distal end of the guide portion 31. A sprocket 32 that engages with the feed hole that is drilled and a rotation mechanism 34 that rotates the sprocket 32 by one pitch when the feed lever 33 is operated are provided. When the feed lever 33 is operated and the sprocket 32 is rotated by one pitch by the rotation mechanism 34, the component tape 27 is fed by one pitch by the sprocket 32, and the cover tape 27b is peeled off before the component supply position 30. The component P is sent to the component supply position 30 while being stored in the cavity of the carrier tape 27a, and is sucked by the suction nozzle 21 of the component transfer device 17 and mounted on the substrate B. The carrier tape 27a from which the component P has been taken out is collected below the main body 24, and the peeled cover tape 27b is taken up on the collection reel 35.

  The reel 25 in which the component tape 27 wound around the reel 25 is shortened and the number of components P held on the reel 25 is equal to or less than a predetermined number is the reel 25 around which the component tape 27 is wound to the outer diameter portion, That is, it is replaced with a reel 25 full of parts P. In order to prevent the operator from mistakenly replacing the reel 25 and mounting the wrong reel 25 to the reel mounting portion 26 when the reel 25 is replaced, the reel mounting portion 26 holds the reel 25. When the reel confirmation sensor 41 detects that the reel 25 is not held by the reel mounting portion 26 in the reel confirmation sensor 41 to be detected and the two or more tape feeders 22, the execution of the reel 25 replacement operation is rejected. Exchange control means 39 is provided.

  As shown in FIG. 3, the reel mounting portion 26 has an arm 42 that supports a support shaft 36 that fits in the center hole of the reel 25 and rotatably supports the reel 25, and a normal operation position 37 and a reel replacement position 38. It is mounted so that it can swing between the two. A reel confirmation sensor 41 is attached to the arm 42 so as to face the boss portion 25 a of the reel 25. Since the boss portion 25a exists over the entire circumference, when the reel 25 is supported by the support shaft 36, the reel confirmation sensor 41 mounts the reel 25 on the reel mounting portion 26 regardless of the rotation position of the reel 25. It is detected that As the reel confirmation sensor 41, a reflective sensor having a light source that emits light toward the boss portion 25a of the reel 25 and an optical sensor that detects reflected light from the boss portion 25a may be used. In addition, the reel confirmation sensor 41 may be attached to the arm 42 so as to face the rim portion 25b existing over the entire outer periphery of the reel 25.

  In FIG. 4, the substrate transfer device 12, the component transfer device 17, the component supply device 10, the reel confirmation sensor 41, and the like are connected to the control device 40, and the input device 43, the display device 44, and the like are connected to the control device 40. Device 47 is connected wirelessly. As shown in the correspondence table T of FIG. 5, the storage device 45 of the control device 40 is mounted at each feeder mounting position 23 corresponding to the position numbers S1 to Sn of the feeder mounting positions 23 of the component supply device 10. The identification codes F1 to Fn of the feeders attached to the tape feeders 22 being identified, the identification codes R1 to Rn attached to the reels 25 attached to the respective tape feeders 22, and wound around the reels 25. The types P1 to Pn of the parts P (hereinafter referred to as the parts P held on the reels 25) held on the part tape 27, the remaining numbers A1 to An of the parts P held on each reel 25, etc. It is remembered. Further, in the storage device 45, the reel replacement instruction program executed when the component tape 27 wound around the reel 25 is shortened and the remaining number A of the components held on the reel 25 becomes a predetermined number or less, and the component supply A mounting program or the like for storing the component P transferred to the position 30 by the suction nozzle 21 and mounting it on the substrate B is stored.

  Next, the operation of the present embodiment will be described. When the component P is mounted on the board B, when the mounting start switch is pushed by the operator, the microcomputer of the control device 40 executes the mounting program, and each device operates based on the control signal from the control device 40. Is done. That is, the substrate transfer device 12 carries the substrate B to a predetermined position, and is positioned and held by the clamp device at that position. The substrate recognition camera 28 is moved onto the substrate transport device 12 by the movable table 18, images the substrate B that has been positioned and held, and transmits image information to the control device 40. Based on this image information, the control device 40 corrects the mounting position of the component P on the board B according to the positioning error of the board B. The suction nozzle 21 is positioned at the component supply position 30 of the tape feeder 22 that stores the component P placed on the substrate B by the movement of the moving table 18, and the component transfer device 17 supplies the component by the suction nozzle 21. The component P supplied to the position 30 is sucked, moved to the mounting position on the board B, and mounted on the board B. When the component transfer device 17 sucks the component P of the identification code Pi supplied to the component supply position 30 by the suction nozzle 21, the remaining amount Ai of the component P of the identification code Pi of the correspondence table T is decremented by 1 (Ai -1).

  The mounting of the component P onto the substrate B by the component transfer device 17 is continuously executed, and the component P held by the component tape 27 wound around the reel 25 mounted on the tape feeder 22 is stored. When the remaining number A falls below the predetermined number Al and the reels 25 need to be replaced, only one tape feeder 22 at a time allows the reels 25 to be removed from the reel mounting portion 26 and allowed to be replaced by splicing. The reel replacement instruction program shown in FIG. 6 is executed.

  In step S1, the control device 40 searches the correspondence table T for the identification code Rc of the reel 25 in which the remaining number A of the parts P is equal to or less than the predetermined number Al, and displays it on the display device 44 as the replacement reel Rc. The tape feeder Fc to which the reel Rc is mounted and the feeder mounting position Sc to which the tape feeder Fc is mounted are retrieved from the correspondence table T and displayed on the display device 44 (step S1). Here, the reel 25 with the identification code Rc is called the reel Rc. Similarly, the identification code Fc, the position number Sc, the type Pc, the tape feeder 22, the feeder mounting position 23, and the component P are the tape feeder Fc and feeder, respectively. It is referred to as position Sc and component Pc. Since the feeder mounting position Sc of the tape feeder Fc on which the replacement reel Rc is mounted is displayed on the display device 44, the operator can specify the tape feeder Fc and one reel that needs to be replaced. In the tape feeder Fc, a splicing operation is performed to replace the replacement reel Rc with a replenishment reel Rc1 around which the component tape 27 holding the component Pc is wound to the outer diameter portion.

  In one tape feeder Fc that requires reel replacement, the arm 42 of the reel mounting portion 26 is rotated to the reel replacement position 38, and the replacement reel Rc is removed from the reel mounting portion 26 (step S2). When the reel confirmation sensor 41 detects that the reel Rc has been removed from the reel mounting portion 26 (step S3), the identification code Rc1 of the supplementary reel 25 is read by the code reader 46 (step S4). The code reader 46 is connected to a terminal device 47 that is carried by an operator and can communicate with the control device 40 wirelessly. It is determined whether or not the reel confirmation sensor 41 of the other tape feeder 22 detects that the reel 25 has been removed from the reel mounting portion 26 (step S5). If it is detected, that is, if the reel confirmation sensor 41 detects that the reel 25 is not held by the reel mounting portion 26 in the two or more tape feeders 22, the controller 40 determines that an error has occurred, and so on. The execution of the splicing operation is rejected, and the termination of splicing is displayed on the terminal device 47 (step S6).

  If the reel 25 is not removed from the reel mounting portion 26 in the other tape feeder 22, the type of the component P held on the supplementary reel Rc1 matches the type Pc of the component P held on the replacement reel Rc. Is determined (step S7). In the storage device 45, the identification code Ri of the reel 25, the type Pi of the component P held on the reel Ri, and the initial number Afi of the component Pi held on the reel Ri in the initial state are associated with each other. And remembered. If the type of the component P held on the replenishing reel Rc1 does not match the type Pc of the component P held on the replacement reel Rc, the control device 40 determines that there is an error and refuses to execute the subsequent splicing operation ( Step S6). If they match, the operator performs a splicing operation to connect the rear end of the component tape 27 removed from the replacement reel Rc to the front end of the component tape wound around the replenishing reel Rc1, and the replenishing reel Rc1 is connected to the tape feeder Fc. The reel mounting unit 26 is mounted, and the reel mounting unit 26 is returned to the normal operation position. (Step S8). When the reel confirmation sensor 41 detects that the replenishment reel Rc1 is mounted on the reel mounting portion 26 of the tape feeder Fc (step S9), the control device 40 selects the reel corresponding to the feeder mounting position Sc in the correspondence table T. Is the value obtained by adding the initial number Afc of the component Pc held on the supplementary reel Rc1 to the remaining number Ac of the component Pc held on the reel Rc at that time. (Step S10). It is determined whether there are other reels 25 in which the remaining number A of the parts P is equal to or less than the predetermined number Al (step S11). If there are any, the steps S1 to S10 are repeatedly executed. To do. When this reel replacement instruction program and control device 40 detects that the reel 25 is not held by the reel mounting portion 26 in the two or more tape feeders 22, the reel confirmation sensor 41 detects that the reel 25 is replaced. The exchange control means 39 which refuses is comprised.

  In the first embodiment, a reel 25 around which a component tape 27 that holds a plurality of components P is wound is a component holder that holds a plurality of components, and a reel mounting portion 26 to which the reel 25 is mounted includes: It is a holder mounting part to which a component holder is mounted, and the tape feeder 22 is a component supply unit. A reel confirmation sensor 41 that detects that the reel 25 is held by the reel mounting portion 26 is a detection device that detects that a component holder is mounted on the holder mounting portion, and two or more tapes When the reel confirmation sensor 41 detects that the reel 25 is not held by the reel mounting portion 26 in the type feeder 22, the replacement control means 39 that rejects the replacement operation of the reel 25 includes two or more component supply units. When the detection device detects that the component holder is not held in the holder mounting portion, the replacement control means rejects execution of the component holder replacement operation.

  In the first embodiment, the detection device for detecting that the component holder is mounted on the holder mounting portion is such that the reel confirmation sensor 41 includes the normal operation position 37 and the reel replacement position 38 of the reel mounting portion 26. However, the present invention is not limited to this, but is mounted on the arm 42 that can move between the boss 25a and the rim 25b of the reel 25. As shown in FIG. 7, the main body 24 of the tape feeder 22 is such that the reel confirmation sensor 41 faces the outer peripheral rim portion 25 b of the reel 25 supported by the support shaft 36 on the arm 42 moved to the normal operation position 37. It may be attached to. In this way, the reel confirmation sensor 41 detects the reel 25 held by the reel mounting portion 26 when the reel 25 is held by the arm 42 moved to the normal operation position 37. It is possible to more reliably detect that the reel 25 is not held by the reel mounting portion 26 in the two or more tape feeders 22.

  Further, as shown in FIG. 9, the detection device for detecting that the component holder is mounted on the holder mounting portion has a proximity switch 48 operated by the arm 42 moved to the normal operation position 37. You may comprise by attaching to the main body 24 of the type | formula feeder 22. FIG. Normally, the arm 42 is moved to the normal operation position 37 while the reel 25 is supported by the support shaft 36. Therefore, when the proximity switch 48 detects that the arm 42 has been moved to the normal operation position 37, The fact that the reel 25 is mounted on the reel mounting portion 26 can be indirectly detected.

  As shown in FIG. 9, when the reel 25 is rotatably supported in a reel support case 50 provided at the rear end of the tape feeder 22, the reel confirmation sensor 41 is supported in the reel support case 50. A detection device for detecting that the component holder is mounted on the holder mounting portion is configured by being attached to the reel support case 50 so as to face the boss portion 25a or the rim portion 25b of the reel.

  In the above embodiment, when the reel confirmation sensor 41 detects that the reel 25 is not held by the reel mounting portion 26 in the two or more tape feeders 22, the execution of the splicing operation is rejected. However, in the tape type feeder in which the component tape 27 wound around the replenishing reel Rc1 is loaded into the component transfer device instead of the splicing operation, execution of the tape loading operation is refused.

  That is, for example, as in a tape feeder described in Japanese Patent Application Laid-Open No. 2005-142574, the rear end of the component tape removed from the replacement reel Rc and the front end of the component tape wound around the supply reel Rc1 are connected. When the component tape wound around the replenishing reel Rc1 can be easily loaded into the component transfer device, the tape feeder equipped with the replacement reel Rc in which the remaining number A of the component P is equal to or less than the predetermined number Al. In Fc, following the rear end of the component tape removed from the replacement reel Rc, the tip portion of the component tape wound around the replenishing reel Rc1 may be loaded into the component feeder of the tape feeder. In this case, a reel confirmation sensor 41 for detecting that the reel 25 is held in the reel mounting portion 26 is provided, and it is confirmed that the reel 25 is not held in the reel mounting portion 26 in two or more tape feeders 22. When detected by the sensor 41, the exchange control means 39 refuses to execute the reel exchange operation including the tape loading operation.

  In the component supply apparatus 10 of the above embodiment, the component holder that holds a plurality of components is a reel 25 around which a component tape 27 that holds a plurality of components is wound. However, as shown in FIG. It is good also as the bulk case 60 which accommodates these components. The bulk case 60 is detachably attached to the case attachment portion 62 of the bulk feeder 61. The bulk type feeder 61 includes a main body 63, a case mounting portion 62 provided on an upper portion of the main body 63 to which the bulk case 60 is detachably mounted, and a component transfer device that transfers the component P from the bulk case 60 to the component supply position 64. 65. The component transfer device 65 includes an endless conveyance belt 67 that transfers the component P dropped from the bulk case 60 via the chute 66 to the component supply position 64. The conveying belt 67 is stretched between the driving wheel 68 and the driven wheel 69, and the driving wheel 68 is rotated by the lever 71 and the ratchet mechanism 72 driven by the operation of the feed lever 70, so that the conveying belt 67 is rotated by one pitch. The parts P are moved one by one and transferred one by one to the part supply position 64.

  In this case, a case confirmation sensor 64 for detecting that the bulk case 60 is attached to the case attachment part 62 is provided, and the bulk case 60 is not attached to the case attachment part 62 in the two or more bulk type feeders 61. When detected by the case confirmation sensor 64, the exchange control means 39 rejects the execution of the exchange work of the bulk case 60.
