The position of F with respect to the peeling member 37 is the same.

  In the cover tape peeling method using the peeling member 37, first, the tip 43 is inserted between the base tape 21 and the cover tape 22 with respect to the carrier tape 17 running on the tape path 32 (FIG. 12A). Then, one end of the cover tape 22 in the width direction of the cover tape 22 (here, the end on the end of the base tape 21 and referred to as an outer end) is separated from the base tape 21 (separation step, FIG. 13A). (FIG. 13 (b)). Specifically, while the cover tape 22 is lifted with respect to the base tape 21 by the upper surface of the distal end portion 43 of the peeling member 37, the adhesive portion at the outer end portion of the cover tape 22 is formed by the edge on the outer end portion side of the distal end portion 43. 22T is peeled off from the base tape 21 (FIG. 13B).

  When the outer end portion of the cover tape 22 is separated from the base tape 21 by the front end portion 43, the outer end portion of the cover tape 22 separated from the base tape 21 is pressed against the carrier tape 17 running on the tape path 32. After being pushed down by 42 (FIGS. 12B and 13C), the cover tape 22 is pressed in the width direction by the pressing surface 42 and the other end of the cover tape 22 (of the base tape 21) is pressed. The end on the center side is referred to as the inner end. In this process, the cover tape 22 is compacted by pressing in the height direction at the ceiling portion 36a of the tape guide 36 (pressing process; FIG. 14 (a) → FIG. 14 (b) → FIG. 14 (c)). .

  In the pressing step, the cover tape 22 whose outer end portion is peeled off by the peeling member 37 maintains the state where the inner end portion is adhered to the base tape 21, while the inner end portion side of the cover tape 22 (base tape side). 21 (the central part side) 21 (FIG. 13 (c) → FIG. 14 (a) → FIG. 14 (b) → FIG. 14 (c)). At this time, the portion on the outer end portion side of the cover tape 22 is guided to the upper surface (concave surface) of the concave surface portion 45 of the peeling member 37 and is rolled on the lower surface side of the cover tape 22. In the process of being moved toward the side (the central portion side of the base tape 21), a roll-shaped lump 22G (FIGS. 12C, 14C, and 15) is formed. As a result, each component storage portion 23 of the carrier tape 17 is opened when it reaches the component supply position 16K of the tape feeder 16, and the component PT can be picked up (sucked) by the suction nozzle 13a.

  Since the other end portion (inner end portion) side of the cover tape 22 after being peeled is kept attached to the base tape 21, the cover tape 22 after being peeled is discharged together with the base tape 21. Can do. Here, the roll-shaped lump 22G of the cover tape 22 remaining on the base tape 21 not only has a compact shape suitable for discharge, but also an adhesive portion at the end (outer end) on the side separated from the base tape 21. Since 22T is wound inside, the adhesive portion 22T does not adhere to the member on the tape passage 32 of the tape feeder 16 (here, the inner surface of the tape guide 36), and the cover tape 22 can be smoothly discharged. is there. Moreover, since it is not necessary to provide a space in the height direction as compared with the peeling method of folding the cover tape 22 after peeling, the tape feeder 16 can be reduced in size.

  As described above, in the tape feeder 16 in this embodiment (and the cover tape peeling method in the tape feeder 16), one end portion (outer end portion) of the cover tape 22 peeled from the base tape 21 is peeled off. After being pushed downward by the pressing surface 42 of the member 37, the cover tape is moved toward the other end side (inner end side) of the cover tape to cover the adhesive portion 22T on the side of the cover tape 22 separated from the base tape 21. The tape 22 is wound inside. Since the adhesive portion 22T of the cover tape 22 is immediately exposed to the inside of the cover tape 22 without being exposed to the outside immediately after the cover tape 22 is peeled off, the cover tape 22 is discharged together with the base tape 21. Therefore, the cover tape 22 after peeling can be smoothly discharged without being attached to the member on the tape passage 32.

  Provided are a tape feeder and a cover tape peeling method in the tape feeder that can prevent the adhesive portion of the peeled cover tape from adhering to a member on the tape path and smoothly discharge the cover tape.
