  • the reel holder 40 also has a reel holder 41 that rotatably holds the tape reel 3, and further has a collection box 42, a peeling portion 46, a second sprocket 43, and a gear 44.
  • the reel holder 41 and the collection box 42 are integrated in a reel holder 40 that can be attached and detached to the feeder body 30. For this reason, for example, when the feeder 20 runs out of parts during board production, the reel holder 40 can be removed from the feeder body 30, and the tape reel 3 that has run out of parts and the collection box 42 that is full of cover tape 2b can be simultaneously separated from the feeder body 30, including the drive unit 31, second drive source 37, and control unit 39, and collected together. Also, by attaching the reel holder 40 to the feeder body 30, a new tape reel 3 and an empty collection box 42 without cover tape 2b can be simultaneously integrated into the feeder body 30.
  • the reel holder 40 does not incorporate the drive unit 31, the second drive source 37, and the control unit 39. Therefore, the reel holder 40 itself is less expensive than the entire feeder 20 including the feeder body 30. Therefore, even when it is necessary to prepare surplus equipment, for example, in consideration of a setup change, it is not necessary to prepare the entire feeder 20 including the feeder body 30 as surplus equipment, and it is sufficient to prepare the reel holder 40 as surplus equipment. This makes it possible to keep the equipment costs for feeder operation lower than when the entire feeder 20 including the feeder body 30 is prepared as surplus equipment. In addition, the space for storing surplus equipment in an external setup area, etc., can be limited to the reel holder 40. This makes it possible to save space in storing the feeder 20.
  • the reel holder 40 is provided with a peeling section 46 that peels the cover tape 2b from the base tape 2a of the carrier tape 2.
  • the peeling section 46 has a folding section that folds back the cover tape 2b that has been peeled off from the base tape 2a of the carrier tape 2 that has been pulled out from the tape reel 3 held by the reel holder 41.
  • the handling of the cover tape 2b that has been peeled off from the base tape 2a can be completed within the reel holder 40.
  • the tip of the cover tape 2b peeled off from the base tape 2a at the peeling section 46 can be held by the tip holder 47, and when the cover tape 2b is held, the tip of the base tape 2a engages with the upper external teeth of the second sprocket 43.
  • the reel holder 40 since it is possible to hold the respective tips of the base tape 2a and cover tape 2b of the carrier tape 2 within the reel holder 40, the reel holder 40 can be transported or attached to the feeder body 30 while holding the base tape 2a and the cover tape 2b peeled off from the base tape 2a.
  • the second drive source 37 In the feeder 20, the second drive source 37 generates a recovery drive force for recovering the cover tape 2b in the recovery box 42, and at the same time generates an auxiliary force for assisting in the feeding and transporting of the carrier tape 2 pulled out from the tape reel 3.
  • the second drive source 37 is disposed in the feeder body 30, and the force generated by the second drive source 37 is transmitted to the reel holder 40 side using a gear 38 and a second sprocket 43.
  • the cover tape 2b peeled off from the base tape 2a of the carrier tape 2 pulled out from the tape reel 3 held in the reel holder 41 of the reel holder 40 can be guided to the collection box 42 within the reel holder 40 without passing through the feeder body 30.
  • the base tape 2a from which the cover tape 2b has been peeled off can be given an auxiliary force for feeding and transporting by the second drive source 37, the carrier tape 2 on the reel holder 40 side can be automatically guided to the component supply position S on the feeder body 30 side immediately after the reel holder 40 is attached to the feeder body 30. Furthermore, since the base tape 2a engages with the external teeth of the first sprocket 34 when it reaches the component supply position S, the feed drive force can then be applied to the base tape 2a by the first drive source 32, and the base tape 2a can be fed and transported sequentially.
  • the feeder information of the feeder body 30 and the reel holder 40, as well as the feeder information of the tape reel 3, is read, and the feeder information is associated with each other and stored in a storage unit such as a host computer. Then, after the feeder information is stored, the setting of the feeder 20 into the slot 11 of the component mounting machine 1 is controlled based on the feeder information. Therefore, one reel holder 40 can be selected from multiple types of reel holders 40, and the feeder 20 attached to the feeder body 30 can be appropriately associated with the built-in carrier tape 2, and the mounting of components on the board in the component mounting machine 1 can be appropriately performed.
  • the reel holder 40 when the reel holder 40 is removed from the feeder body 30 of the feeder 20, the feeder information of the feeder body 30, the reel holder 40, and even the tape reel 3 is read, and the feeder information is deleted from the memory unit. Therefore, the association between the feeder 20 and the carrier tape 2 can be dissolved after the reel holder 40 is removed from the feeder body 30, and it is possible to avoid the association continuing for an unnecessarily long period of time.
  • the cover tape 2b of the carrier tape 2 is completely peeled off from the base tape 2a at the peeling portion 46, and the reel holder 40 has a recovery box 42 for recovering the cover tape 2b.
  • the present disclosure is not limited to this, and the cover tape 2b may be so-called partially peeled off from the base tape 2a, and after the components are removed from the component storage section in this partially peeled state, the cover tape 2b may be rejoined to the base tape 2a and discharged together with the base tape 2a to the outside of the feeder.
  • control unit 39 controls the driving of both the first driving source 32 and the second driving source 37.
  • control unit 39 may control the driving of only the first driving source 32.
