And Similarly, the packaging sheet bag affixed at the nth position is designated as a packaging sheet bag 54n, the upper packaging sheet is designated as 53n, the lower packaging sheet is designated as 52n, and the built-in filter paper is designated as 51n. .
[0028]
Peeling step 1. When the operating means 14 is operated so that the pin 24 reaches the lowest point, the lower sheet winding means 11 and the upper sheet winding means 6 rotate by a certain angle. Accordingly, the adhesive tape 7 and the adhesive tape 1 are pulled, and the lower wrapping sheet peeling means 10, the upper wrapping sheet peeling means 5, the adhesive tape applying pressure means 9, the adhesive tape pressing means 4, and the adhesive tape sending means 8 are also provided. The adhesive tape sending means 2 also starts rotating.
[0029]
1. Peeling step When the pressure-sensitive adhesive tape pressing means 4 rotates, the pin 24 moves with it and reaches the lowest point, and the spring 23 expands.
[0030]
2. Peeling step Then, the pressure-sensitive adhesive tape pressing means 3 presses the surface of the separated pressure-sensitive adhesive tape 1 on which the pressure-sensitive adhesive is applied, against the upper packaging sheet 53a of the packaging sheet bag 54a sent out from the packaging sheet bag sending means 12.
[0031]
Peeling step 4. When the operating means 14 is operated so that the pin 24 reaches the uppermost point, the packaging sheet bag 54a attached to the adhesive tape 1 is separated from the packaging sheet bag sending means 12, and the packaging sheet bag sending means 12 is By the action, the packaging sheet bag 54b is sent out.
[0032]
Peeling step 5. The following steps are performed while repeating the peeling steps 1 to 4.
[0033]
Peeling step 6. The packaging sheet 54a attached to the adhesive tape 1 starts to reach the adhesive tape pressurizing means 4, and the adhesive tape 7 passed through the adhesive tape applying pressure means 9 starts to be attached to the lower packaging sheet 52a. (FIG. 4)
[0034]
Peeling step 7. Then, the packaging sheet bag 54a is sandwiched between the pressure-sensitive adhesive tape pressing means 4 and the pressure-sensitive adhesive tape applying pressure means 9, and the upper packaging sheet 53a and the lower packaging sheet 52a forming the packaging sheet bag 54a are made of adhesive. The tape 1 and the adhesive tape 7 are completely attached. (FIG. 5)
[0035]
Peeling step 8. The packaging sheet bag 54a completely adhered to the adhesive tape 1 and the adhesive tape 7 moves between the upper packaging sheet peeling means 5 and the lower packaging sheet peeling means 10.
[0036]
Stripping step 9. The upper wrapping sheet 53a and the lower wrapping sheet 52a of the wrapping sheet bag 54a are formed by the winding action of the upper sheet winding means 6 and the lower sheet winding means 11 and the adhesive force of the adhesive tape 1 and the adhesive tape 7. Then, peeling of the upper wrapping sheet 53a and the lower wrapping sheet 52a starts, and the filter paper 51a contained in the wrapping sheet bag 54a is exposed. (FIG. 6)
[0037]
Peeling step 10. The exposed filter paper 51a is picked up with tweezers or the like.
[0038]
Peeling step 11. The peeled upper packaging sheet 53a and lower packaging sheet 52a move while being adhered to the adhesive tape 1 and the adhesive tape 7, respectively.
As described above, the filter paper 51n can be obtained from the packaging sheet bag 54n.
[0039]
