[0039]

Fifth Embodiment In each of the above embodiments, the peeling edge 12 is advanced and the adhesive hand 8 is held by the suction hand 22, and the peeling edge 12 is retracted to sequentially change the peeling position of the adhesive piece 8 while sequentially changing the peeling position. Although the description has been given of the case where the adhesive part 8 is peeled from the adhesive sheet 8, an example in which the adhesive part 8 is peeled from the release paper 9 while the peeling position of the adhesive part 8 is sequentially changed while the peeling edge 12 is fixed will be described.

In the case of this embodiment, a supply reel 10, a guide roller 11 disposed between the supply reel 10 and the release mechanism 6, and a pressing roller 19 And a feed roller 20 connected to a feed motor 30 by a drive belt or a gear mechanism. The supply reel 10 has a slit 40 along the center line as shown in the plan view of FIG. 10A and the cross-sectional view of FIG.
A release paper 9 on which an adhesive component 8 is adhered at a predetermined interval is wound. The peeling edge 121 is fixed to the peeling mechanism 6.
Having. The peeling edge 121 comes into contact with the peeling paper 9 to which the adhesive component 8 has been attached as shown in the plan view of FIG. 11A, the front view of the tip side of FIG. 11B, and the side view of FIG. The top surface is formed flat, and the center of the tip is cut out in a V-shape, and has a first edge 122 and a second edge 123 formed as knife edges on both sides of the V-shape. On the downstream side of the first edge 122 of the peeling edge 121, there is provided a release paper collecting mechanism 71, and the second edge 123
A release paper collecting mechanism 72 is provided on the downstream side. The release paper collecting mechanisms 71 and 72 have a drawing mechanism 41, a guide roller 18 and a collecting reel 21, respectively. Extension mechanism 41
Is composed of, for example, a tension roller, and always applies an appropriate tension to the release paper 9 from which the adhesive component 8 has been released, so that the release paper 9 is adjusted so as not to be loosened.

In the adhesive component supply device 1 configured as described above, when the adhesive component 8 stuck on the release paper 9 is peeled, the feed roller 20 is rotated to rotate the feed roller 20 as shown in FIG. The slit 40 of the release paper 9 is
The release paper 9 to which the adhesive component 8 is attached is sent out while being positioned so as to coincide with the connection point between the first edge 122 and the second edge 123. The sent release paper 9 is a release edge 12
When the sheet is folded at the first edge 122 and the second edge 123, one of the separated release papers 91 separated by the slit 40 is recovered by the release paper recovery mechanism 71, and the other release paper 92 is separated by the release paper 92. Collected by the collection mechanism 72.
When the release paper 9 is separated into the release paper 91 and the release paper 92 at the release edge 121, the first edge 122 and the second edge 123 are formed in a V-shape as a connection point with the center line of the release edge 121. After that, the release paper 9 sent to the release edge 121 is sequentially folded from the center line to the outside by the first edge 122 and the second edge 123. Therefore, the center line of the adhesive component 8 is first separated from the release paper 9, and the separated position sequentially moves to the left and right outer sides, so that the adhesive component 8 can be reliably separated.

Further, since the peeling position is shifted to the left and right sides sequentially from the center line portion of the adhesive component 8 and peeled off, when the adhesive component 8 is peeled, the flat surface on the upper surface of the peeling edge 121 is used. Since the area for holding the component 8 can be increased and held on the left and right outer sides of the adhesive component 8, even if the peeled adhesive component 8 is formed of a flexible member, it is bent or deformed. Can be prevented. As the peeling of the adhesive component 8 progresses, as shown in FIG. 12B, when the peeling area of the adhesive component 8 reaches a predetermined amount, the rotation of the feed roller 20 is stopped and the suction hand 22 is lowered. Then, the adhesive component 8 peeled off by a predetermined amount is held. Since the left and right outer sides of the adhesive component 8 are held by the peeling edges 121 when the adhesive component 8 is sucked and held by the suction hand 22, the adhesive component 8 can be stably sucked and held by the suction hand 22.
