The thickness direction dimension of the base portion 41 substantially coincides with the thickness direction of the carrier tape 17, and the rear end surface of the base portion 41 is formed in a flat shape.

When the peeling assist tool 40 is attached to the leading portion of the carrier tape 17, the operator OP cuts the leading portion of the carrier tape 17. At this time, the leading portion 22S of the cover tape 22 that has been peeled off from the base tape 21 in advance is set to protrude from the leading portion 21S of the base tape 21 so as to extend (FIG. 7A). By peeling from the base tape 21 in advance, the position accuracy at which the peeling member 37 enters (interrupts) between the base tape 21 and the cover tape 22 is compared with the method of directly peeling the leading portion of the carrier tape 17. Is not required, and peeling can be facilitated.

After cutting the tip of the carrier tape 17, the operator OP rolls up the head portion 22S of the cover tape 22 (warps it upward), and then attaches the peeling assist tool 40 to the end surface of the head portion 21S of the base tape 21. The rear end faces are brought into contact with each other. Then, the adhesive tape NT is attached so as to straddle the upper surface of the base 41 of the peeling auxiliary tool 40 and the upper surface of the base tape 21 (FIG. 7 (b) → FIG. 8 (a)). As a result, the peeling auxiliary tool 40 is connected to the leading portion 21S of the base tape 21. In this way, the peeling auxiliary tool 40 can be easily connected to the carrier tape 17.

When the peeling auxiliary tool 40 is connected to the leading portion 21S of the base tape 21, the cover tape 22 is returned to its original state (FIG. 8 (b)). At this time, since both ends of the cover tape 22 ride on the upper surfaces of the two cover tape support portions 42, the head portion 22S of the cover tape 22 that has been peeled off from the head portion 21S of the base tape 21 is in a lifted state with respect to the base 41. It will be in a state of being supported by. As a result, the upper surface of the base 41 of the peeling auxiliary tool 40 and the cover tape 22 are kept separated from each other, and as a result, the peeling member 37 is separated between the base tape 21 and the cover tape 22 at the leading portion of the carrier tape 17. A gap SP is formed so that the tip portion 37H of the above can enter (FIGS. 9 (a) and 9 (b). Gap forming step).

As described above, in the present embodiment, the peeling auxiliary tool 40 attaches the base 41 connected to the leading portion 21S of the base tape 21 and the leading portion 22S of the cover tape 22 previously peeled from the base tape 21 to the base 41. The cover tape support portion 42 is provided to support the carrier tape 17 in a lifted state and to form a gap SP for allowing the release member 37 to enter between the base tape 21 and the cover tape 22 when the carrier tape 17 runs in the tape feeder 16.

The through groove 43 is formed in the outer peripheral teeth (feed sprocket outer peripheral teeth 33T, secondary sprocket outer peripheral teeth 34T) of the sprocket (feed sprocket 33, secondary sprocket 34 and main sprocket 35) on which the tape feeder 16 allows the carrier tape 17 to travel in the tape feeder 16. And functions as an interference avoidance unit for avoiding interference with the main sprocket outer peripheral teeth 35T). Therefore, even if the peeling auxiliary tool 40 is attached to the leading portion of the carrier tape 17, the feeding operation of the carrier tape 17 by the sprocket is not affected.

When the leading portion of the carrier tape 17 to which the peeling assist tool 40 is attached is inserted into the tape passage 32 of the main body 31 from the tape inlet 32a of the tape feeder 16, the feed sprocket 33 rotates and the carrier tape 17 travels forward. The carrier tape 17 traveling forward in the tape passage 32 is pitch-fed by the secondary sprocket 34 when the feed hole 24 reaches a position where it can engage with the secondary sprocket outer peripheral teeth 34T. When the carrier tape 17 is pitch-fed by the secondary sprocket 34, the feed operation of the carrier tape 17 by the feed sprocket 33 is stopped, and thereafter, the feed sprocket 33 is in a state of being rotated by the carrier tape 17.

When the carrier tape 17 starts to be pitch-fed by the secondary sprocket 34, the leading portion of the carrier tape 17 approaches the tip portion 37H of the peeling member 37. Then, the tip portion 37H of the peeling member 37 enters the gap SP between the base tape 21 and the cover tape 22 (FIGS. 10 (a) → 10 (b) and 11 (a) → 11 (b)). . Entry process).

When the carrier tape 17 is further pitch-fed by the secondary sprocket 34 with the tip 37H of the peeling member 37 entering the gap SP between the base tape 21 and the cover tape 22, the tip 37H of the peeling member 37 becomes the base tape. It enters between the cover tape 21 and the cover tape 22, and the cover tape 22 is peeled off from the base tape 21 (FIG. 12).

As described above, in the present embodiment, while the carrier tape 17 is running in the tape feeder 16, the peeling member 37 is inserted between the base tape 21 and the cover tape 22 to peel the cover tape 22 from the base tape 21. The cover tape peeling method is adopted. Then, in this cover tape peeling method, the peeling auxiliary tool 40 is connected to the leading portion 21S of the base tape 21, and the leading portion 22S of the cover tape 22 previously peeled from the base tape 21 is connected to the cover tape supporting portion of the peeling auxiliary tool 40. A step of forming a gap SP between the upper surface of the base 41 and the leading portion 22S of the cover tape 22 by being supported by the 42 (the above-mentioned gap forming step) and a step of running the carrier tape 17 in the tape feeder 16 to run the carrier tape 17 on the base 41. It has a step (the above-mentioned entry step) of inserting the peeling member 37 into the gap SP formed between the upper surface and the leading portion 22S of the cover tape 22.

The component storage portion 23 of the base tape 21 which was pitch-fed by the secondary sprocket 34 and the main sprocket 35 and from which the cover tape 22 was peeled off was opened upward when it was located at the component supply position 16K of the tape guide 36 (FIG. FIG. 6 (b)), the component PT can be picked up by the suction nozzle 13a. The base tape 21 is discharged from the tape outlet 32b of the main body 31 after the component storage portion 23 has passed the component supply position 16K. On the other hand, the peeled cover tape 22 advances forward together with the base tape 21 while being rolled or crushed in the width direction in the space between the base tape 21 and the tape guide 36, and the tape guide 36 It is discharged from the tip.

After the tail of the carrier tape 17 is pitch-fed by the main sprocket 35, the carrier tape 17 loses the driving force for traveling forward. The carrier tape 17 (referred to as a leading carrier tape) that has lost the driving force that the tape feeder 16 travels in advance and travels forward is subjected to the carrier tape 17 that is subsequently pitch-fed by the tape feeder 16. It is extruded and discharged from the tape outlet 32b. In this case, as shown in FIG. 13, the subsequent carrier tape 17 has a contact portion 44 (FIG. 3 (b)) at the tip of the peeling auxiliary tool 40 attached to the front portion thereof and a tail portion of the preceding carrier tape 17A. Is brought into contact with the tape and pressed toward the tape outlet 32b.
