As shown in FIG. 2, the feeder 10 is detachably set on the main body 10 a of the feeder and reel 11 around which the component housing tape A is wound, a feed mechanism 12 that feeds the component housing tape A in the transport direction, A peeling part 13 for peeling the cover tape C as the second tape in the component housing tape A from the carrier tape B as the first tape, and a collection reel 14 for collecting the cover tape C peeled off by the peeling part I have.
The feeder 10 feeds (conveys) the component housing tape A wound around the reel 11 by the feeding mechanism 12 in the conveying direction (see the arrow in FIG. 2), and the carrier at the peeling portion 13 in the middle of the conveying. The cover tape C is peeled off from the tape B by winding it on the collection reel 14. The peeled cover tape C is sequentially collected on the collection reel 14 by being wound around the collection reel 14. The carrier tape B is conveyed below the feeder 10 main body and discharged to the outside of the feeder 10.

  As shown in FIGS. 3 to 5, the peeling portion 13 includes an adjustment piece 15 as a first peeling member provided in the main body portion 10 a, an advance / retreat piece 16 as a second peeling member, and the like.

The adjustment piece 15 is provided so that its tip end portion 15a is directed in the direction in which the component housing tape A is conveyed (the direction of the arrow a in the figure). The adjustment piece 15 is formed with a long hole 15b in the longitudinal direction of the feeder 10 and along the direction in which the component housing tape A is conveyed. The adjustment piece 15 is fixed by a set screw 15c inserted through the long hole 15b. Is fixed to the main body 10a.
That is, the adjustment piece 15 is provided so as to be moved in the longitudinal direction of the feeder 10 with respect to the main body portion 10a of the feeder so that the arrangement position thereof can be adjusted.

The advancing / retreating piece 16 is provided in the main body 10 a via a fixing member 17.
The fixing member 17 has an arrangement groove 17a in which the advance / retreat piece 16 is arranged on one end side, and the other end side is fixed to the main body portion 10a of the feeder by a set screw 17c.

Depending on the thickness of the cover tape C passing through the gap, the thickness of the connection tape affixed by “splicing”, the size of the electronic component D accommodated in the component accommodation tape A, etc. Can be widened or narrowed.

Further, with such advancing / retracting piece 16 of the peeling portion 13, when the cover tape C increased in thickness by the thickness of the connection tape applied by “splicing” reaches the gap of the peeling portion 13, the advance / retreat piece 16 is moved forward and backward. Since the piece 16 can move in a direction to widen the gap of the peeling portion 13, the thick cover tape C smoothly passes through the peeling portion 13, and the component housing tape A is suitably transported. Therefore, the feeder 10 can stably supply the electronic component D to the electronic component supply apparatus 1.
Since the advance / retreat piece 16 is elastically supported so as to be movable in a direction away from the adjustment piece 15, after the gap is widened, the advancement / retraction piece 16 can return to the original arrangement, and the width of the gap of the adjusted separation portion 13 can be restored. Can be maintained.

Further, with such an advance / retreat piece 16 of the peeling portion 13, when the electronic component D accommodated in the component accommodation tape A (carrier tape B) is caught in the gap of the separation portion 13, the advance / retreat piece 16. Can move in the direction of widening the gap of the peeling portion 13, so that the component housing tape A can be sent out so that the electronic component D is smoothly conveyed. Moreover, it can reduce and prevent that the electronic component D is damaged by widening the clearance gap between the peeling parts 13. Therefore, the feeder 10 can stably supply the electronic component D to the electronic component supply apparatus 1.
Since the advance / retreat piece 16 is elastically supported so as to be movable in a direction away from the adjustment piece 15, after the gap is widened, the advancement / retraction piece 16 can return to the original arrangement, and the width of the gap of the adjusted separation portion 13 can be restored. Can be maintained.

  The fixing member 17 including the adjusting piece 15 and the advancing / retracting piece 16 of the peeling portion 13 is provided to be replaced with the main body portion 10a of the feeder by set screws 15c and 17c, respectively. Since the peeling unit can be exchanged according to the electronic component D, the adjusting piece 15 and the advancing / retreating piece 16 having various shapes and sizes are prepared to correspond to various component receiving tapes A and electronic components D. By exchanging as described above, the component housing tape A can be sent out (conveyed) more stably and the electronic component D can be supplied.

  In the above-described embodiment, the peeling unit 13 is provided with the adjustment piece 15 and the advancing / retreating piece 16 (fixing member 17) so that the adjustment piece 15 turns back the cover tape C peeled from the carrier tape B. However, the present invention is not limited to this, and a reverse arrangement may be adopted in which the arrangement is changed so that the advance / retreat piece 16 turns back the cover tape C.
