And the height of the roller 18 are set. Furthermore, the lower surface of the first overhanging plate 30 and the lower surface of the second overhanging plate 32 have the same height, and the height of the lower surface is set at a position higher than the height of the cutter 20 or the roller 18. In FIG. 1, a tape guide 34 is provided at a position close to the facing surface 28 and at a position opposite to the cutter 20 with the roller 18 interposed therebetween. This tape guide 34
Is to prevent the adhesive tape 14 from shifting upward.

Next, a method of using the device 10 will be described.
A description will be given based on FIGS. 4 and 5. The packaging member 36 wraps the laminated paper inside, and the material may be paper or a resin film. As shown in FIG.
The packaging member 36 is placed on a rigid support member 37, and a rigid pressing plate 38 is placed on the top surface of the packaging member 36. The wrapping member 36 supports the supporting member 37 so that the paper laminated inside is parallel to the supporting member 37 and the holding plate 38.
Put on top. Then, the device 1 is placed on the side of the packaging member 36.
0 opposing surfaces 28 are brought into contact. When the opposing surface 28 of the device 10 is in contact with the side surface of the packaging member 36, the device 10 is moved so that the lower surface of the first overhanging plate 30 and the lower surface of the second overhanging plate 32 contact the upper surface of the holding plate 38. And the height of the packaging member 36 are set. That is, the packaging member 36 is sandwiched between the support member 37 and the holding plate 38.

In a state where the opposing surface 28 of the apparatus 10 is in contact with the side surface of the packaging member 36, as shown in FIG. 5, the protrusion length of the cutter 20 is adjusted in advance so that the cutter 20 pierces the packaging member 36. Keep it. When the opposing surface 28 of the device 10 is in contact with the side surface of the packaging member 36, the rollers 18 projecting outward from the opposing surface 28 of the housing 12.
Is pushed to the same plane position as the facing surface 28 by the packaging member 36. As a result, the adhesive tape 14 wound around the roller 18 comes into contact with the packaging member 36.

As a result, as shown in FIG. 5, the cutter 20 cuts the packaging member 36 to form a cut portion 40 in the packaging member 36. The roller 18 immediately contacts the cut portion 40, and the cut portion 40 is adhered by the adhesive tape 14. That is, this device 1
0 is the cutting section 40 on the packaging member 36 covering the laminated paper.
Is formed, and the cut portion 40 is sealed with the adhesive tape 14. In some cases, the cutter 20 may pass through the packaging member 36 to reach the stacked paper, but since the cutter 20 moves parallel to the stack, the paper is not damaged. Further, since the cutter 20 and the roller 18 are arranged close to each other, the cut portion 40 is formed on the packaging member 36, and the cut portion 40 is immediately adhered with the adhesive tape 14, so that the paper jumps out of the packaging member 36. There is no. When the cutting portion 40 is formed on the packaging member 36 by the device 10 and the adhesive tape 14 is adhered, the packaging member 3
6 is sandwiched between the support member 37 and the holding plate 38, so that the formation of the cut portion 40 and the adhesion of the adhesive tape 14 can be performed smoothly.

The cutting portion 40 is formed at a position close to either the upper side or the lower side of the stack, of the height of the side surface of the packaging member 36. It is desirable to form a continuous cut portion 40 on three of the four side surfaces of the packaging member 36 and close the cut portion 40 with the adhesive tape 14. However, at least two sides are sufficient. Further, a continuous cut portion 40 may be formed over four side surfaces, but in that case, a part of one side surface is not cut.

Next, in order to open the packaging member 36 in which the cut section 40 is closed with the adhesive tape 14, as shown in FIG.
Remove 4 Thereby, the cut portion 40 is exposed on the side surface of the packaging member 36. For example, in a state where the cut portions 40 are exposed on the three side surfaces of the packaging member 36, the upper surface and the lower surface of the packaging member 36 are pulled with one hand from the direction B where the cut portions 40 are not provided in FIG. The removed paper can be easily removed. That is, even with one hand, the stacked paper can be easily taken out of the packaging member.

[0016]

As described above, according to the apparatus and method according to the present invention, a cutting portion is formed in a packaging member containing stacked paper sheets in a state parallel to the lamination surface by a cutter.
In addition, the cut portion is immediately bonded with an adhesive tape. Thus, the cut portion can be easily formed on the packaging member without damaging the paper, and the cut portion can be easily sealed without the paper jumping out of the packaging member. As a result, when the adhesive tape adhered to the packaging member is removed, the cut portion is exposed on the side surface of the packaging member, and the paper can be easily taken out from the packaging member with one hand.
