Description of the Related Art When manufacturing a paper box, a carton blank (also referred to as a paper sheet or a blank sheet) is supplied to a folding device, a pre-grooved ruled line portion is bent in a design direction, and a margin of glue is applied. Glue on. The conventional folding device is sequentially provided with a paper feeding unit, a main folding unit, a gluing unit, a guide unit, and a stacker unit (see Japanese Patent Application Publication No. 37460 in 1982).

いてカートンブランクに折りぐせを付けると、カートン
ブランクの罫線部の弾性力は折り込み前のそれと殆ど変
わらない大きさを維持する。そのため、所謂罫線部の腰
が強すぎるので次のような問題がある。When the carton blank is folded using the conventional folding device, the elastic force of the ruled line portion of the carton blank maintains a size substantially the same as that before folding. Therefore, the so-called ruled line portion is too stiff, and there is the following problem.

率が著しく低下する。(1) When a folded carton blank is unfolded, it cannot be unfolded unless a large rising force is applied. Also, even if you get up once, the restoring force is great, so
It becomes difficult to maintain the shape as designed, and it deforms irregularly. (2) When a product is packed in an irregularly deformed paper box using an automatic packing device, troubles frequently occur and work efficiency is significantly reduced.

B1の状態にした。The inventor of the present invention is that the ruled line portion of the carton blank is too stiff because the folding range of the ruled line portion is 18 at maximum.
I thought that there was a cause for being 0 °. Therefore, FIG.
As shown in FIG. 3, the ruled line portion K of the carton blank CB, that is, the bent portion is bent in advance to the outer surface S side, that is, in the direction D2 opposite to the design direction D1 by the bending angle α, to the state of CB2, and then to the inner surface U side, that is, , B in the design direction D1
I made it to B1.

は、上記実験に基づいて本発明を次のように構成した。In this way, the folding range θ of the ruled line portion K
= Fold angle α + fold angle β> 180 °, for example, when the bending range θ = 320 °, the outer surface S of the ruled line portion K
The side and the inner surface U side were subjected to a tensile force and were plastically deformed, and almost no elastic force, that is, restoring force was present on the both surfaces U and S sides. Therefore, the elastic force acts only on the central portion of the ruled line portion K, so that the restoring force is lowered and the strength of the waist is just improved, and the problem of the conventional example is solved. Therefore, the present inventor has configured the present invention as follows based on the above experiment.

ことを特徴とするカートンブランクの折ぐせ方法。A method of folding a carton blank in which a ruled line portion of a carton blank is bent in a design direction; a reverse folding step of bending the ruled line portion in a direction opposite to the design direction, and a normal folding step of bending the ruled line portion in a design direction. A method of folding a carton blank, which comprises:

元力が低下し、腰の強さが丁度良くなる。The folding line portion of the carton blank is bent in the opposite direction to the design direction by the reverse folding means, and then the ruled line portion is folded in the design direction by the normal folding means. Due to the normal folding and the reverse folding, the inner surface side and the outer surface side of the ruled line portion are plastically deformed. for that reason,
Since the elastic force remains only in the central portion of the ruled line portion, the restoring force is reduced and the strength of the waist is just improved.

ブルも発生しない。As described above, according to the present invention, since the ruled line portion of the carton blank is bent in the direction opposite to the design direction and reversely folded, and then folded in the design direction and then forward-folded, the inner surface side and the outer surface of the ruled line portion are The side is plastically deformed by the tensile force. Therefore, compared to the conventional example, the restoring force of the ruled line part is reduced and the waist strength is just improved, so the folded paper box rises and spreads with a small raising force and maintains the box shape as designed. To do. Moreover, since the box shape as designed can be maintained as described above, the product can be inserted smoothly. Therefore, unlike the conventional example, the trouble of the automatic filling device does not occur.
