  Next, a mounting operation of the tape feeder 60 on the mounting portion 51 by the operator will be described. First, the control device 3 displays on the display device 4 (see FIG. 1) the identification number of the tape feeder 60 having the electronic components mounted in the current process and the identification number of the slide portion 52 to which the tape feeder 60 is mounted. . Then, only the magnetic device 80 of the slide unit 52 is turned on to switch from the non-magnetized state to the magnetized state, and the magnetic devices 80 of the other slide units 52 remain off (non-magnetized state).

  The operator reads the identification number of the tape feeder 60 displayed on the display device 4, and replaces the tape feeder 60 with the read identification number with a feeder shelf or carriage in which a plurality of types of tape feeders 60 are stored. Select from. In addition, when the tag with which the barcode was described is affixed on the tape feeder 60, the barcode reader connected to the control apparatus 3 is applied to a tag, and the identification number of the tape feeder 60 is read, and applicable. Whether or not the tape feeder 60 is used can be selected by displaying it on the display device 4.

  Then, the operator reads the identification number of the slide unit 52 displayed on the display device 4, holds the selected tape feeder 60, and touches the lower edge 67 of the tape feeder 60 with the read identification number of the slide unit 52. Close to the neighborhood. As a result, the attracted member 68 formed on the lower edge portion 67 of the selected tape feeder 60 is attracted only to the magnetic device 80 of the slide portion 52 having the read identification number. Even if 52 is hidden behind the tape feeder 60 and cannot be seen, the introduction end of the lower edge portion 67 of the selected tape feeder 60 can be reliably introduced into the introduction port of the slide portion 52 of the identification number. This is particularly effective in the case of a wide tape feeder 60 having large electronic components.

  When the member to be attracted 68 formed on the lower edge portion 67 of the selected tape feeder 60 is a magnet, the magnetic pole of the magnetic device 80 of the slide portion 52 having the read identification number is attracted to the member to be attracted 68. The magnetic poles of the magnetic device 80 of the adjacent slide portions 52 may be reversed. As a result, the attracted member 68 formed on the lower edge portion 67 of the selected tape feeder 60 is attracted to the magnetic device 80 of the slide portion 52 having the read identification number, and is attracted to the magnetic device 80 of the adjacent slide portion 52. On the other hand, since it is repelled, the introduction end of the lower edge portion 67 of the selected tape feeder 60 can be easily introduced into the introduction port of the slide portion 52 having the identification number.

  Then, the operator slides the lower edge portion 67 of the tape feeder 60 along the guide groove 541 of the slide portion 52. At this time, since the plurality of magnetic devices 80 embedded in the guide groove 541 are turned on and switched from the non-magnetized state to the magnetized state, the lower edge portion 67 of the tape feeder 60 has the plurality of magnetic devices 80. Are sequentially sucked and maintained in a state parallel to the guide groove 541. Thereby, the lower edge portion 67 of the tape feeder 60 can be smoothly slid along the guide groove 541 of the slide portion 52. Further, since the lower edge portion 67 of the tape feeder 60 is attracted by the plurality of magnetic devices 80, the operator removes the tape feeder 60 from the tape feeder 60 before the lower edge portion 67 enters the retaining groove 542 of the slide portion 52. Even if the hand is released, the tape feeder 60 can be prevented from falling off from the slide portion 52.

  Then, the operator slides the lower edge portion 67 of the tape feeder 60 along the retaining groove 542 of the slide portion 52, and the pin 65 and the connector 66 of the tape feeder 60 are moved to the concave portion 55 and the connector 56 of the standing surface portion 53. Insert. At this timing, the control device 3 switches the magnetic device 80 of the slide unit 52 from on (magnetized state) to off (non-magnetized state). Thus, the mounting operation of the tape feeder 60 to the mounting portion 51 by the operator is completed. As described above, the component supply device 50 can easily perform the mounting operation of the tape feeder 60 on the mounting portion 51, can reduce the replacement time of the tape feeder 60, and can reduce the man-hours of the operator. Reduction can be achieved.

  In the above-described embodiment, the plurality of magnetic devices 80 are embedded in the bottom surface portion 541a of the guide groove 541 at a predetermined interval. However, when the tape feeder 60 is attached to the attachment portion 51, the feeder main body 62 is provided. Therefore, it is possible to adopt a configuration in which one magnetic device 80 is embedded in the introduction port of the lower edge portion 67 of the feeder main body 62 in the bottom surface portion 541a of the guide groove 541.

  Further, the lower edge portion 67 of the feeder main body 62 is formed so that the cross-sectional shape is inverted T-shaped, and the retaining groove 542 of the slide portion 52 is inverted T-shaped so that the lower edge portion 67 can be fitted. However, the lower edge 67 of the feeder main body 62 is formed in a so-called arigata so long as the effect of guiding and retaining when the tape feeder 60 is attached to and detached from the mounting portion 51 can be obtained. The retaining groove 542 of 52 may be formed in a so-called rim groove. Further, since the lower edge portion 67 of the feeder main body 62 is attracted by the magnetic device 80 and can be easily introduced into the groove portion 54, the groove portion 54 is configured only by the retaining groove 542 without providing the guide groove 541. Also good.

  In addition, the suctioned member 68 made of a magnetic material such as iron or a ferrite magnet is formed at the lower end of the lower edge portion 67 of the feeder main body 62, but the lower edge portion 67 is made of a magnetic material. Since the magnetic device 80 can be attracted, the attracted member 68 may not be formed. In addition, the magnetic device 80 is configured to be switched to one of the magnetic state and the non-magnetic state by the control device 3, but may be configured to be switched by an operator operating a separately provided switch.

  Further, although the electromagnet is embedded in the bottom surface portion 541a of the guide groove 541 as the magnetic device 80, for example, a magnet that can be switched between a magnetic state and a non-magnetic state by a lever or the like is provided on the bottom surface portion 541a of the guide groove 541. It is good also as an embedded structure. In this case, the lever is automatically switched by a separate operating device, or the lever is manually switched by an operator.
