Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a paper folding device.

(Prior Art) As is well known, a paper folding device is composed of a plurality of folding rollers and a buckle, and when the leading edge of the paper fed into the buckle hits a stopper in the buckle, A folding roller absorbs the resulting deflection, thereby creating a fold.

By the way, the accuracy of folding by such a paper folding device is greatly influenced by the straightness of the introduction part of the bundle and the positional relationship between the introduction part and the roller. Therefore, in order to improve the folding accuracy, the positional accuracy of the introduction part is important.

On the other hand, in conventional paper folding apparatuses, the buckle is usually removable in order to avoid paper jams within the buckle or at the folding rollers, or transportation problems. However, in the past, the buckle and the introduction part were constructed as one piece, so when the buckle was removed, the introduction part could hit something and become distorted or damaged. As a result, folding accuracy may deteriorate or paper jams may occur.

(Problem that the invention attempts to solve) This invention allows the buckle to be removed freely,
The purpose of this is to prevent the positional accuracy of the introduction portion from decreasing even with this, and thereby to prevent the folding accuracy from decreasing.

(Means for solving the problem) A mounting base that removably supports the buckle is fixed to a fixed plate, and the tip of the mounting base is connected to a parallel plate fixed to the mounting base. Thus, an introduction section is formed, and the tip of this introduction section is disposed close to the group of folding rollers supported by the fixed plate.

(Function) Since the mount, the introduction section, and the folding roller group are attached to the same fixed plate, their relative positional relationship is constant regardless of the presence or absence of the buckle supported by the mount. Therefore, even when the buckle is removed or attached, the positional accuracy of the introduction part is not impaired.

(Example) An example of this invention will be described with reference to the drawings. Reference numeral 1 denotes a group of folding rollers, and here an example is shown in which the folding rollers are composed of three folding rollers 2 to 4. Each roller is rotatably supported by a fixed plate 5. Reference numeral 6 denotes a buckle, into which paper is fed into a gap 7. Then, the leading edge of the fed paper abuts against the stopper 8, and the creases formed thereby are gripped by the folding rollers 3 and 4, forming a fold. These configurations are not particularly different from ordinary devices of this type. Note that 9 is a knob used to adjust the position of the stopper 8.

According to this idea, a mounting stand for buckle 10
is prepared and fixed to the fixing plate 5 with screws 11 or the like. The mounting base 10 has a step 12 on which the lower end of the buckle 6 rests, thereby determining the position of the mounting point. At that position, it is removably fixed to the mounting base 10 by the mounting screws 13.

Reference numeral 14 denotes an introduction part for introducing paper into the buckle 6. This is constituted by a distal end 15 of a mounting base 10 and a parallel plate 17 arranged in parallel with the distal end 15 with a gap 16 in between. Note that the parallel plate 17 is fixed to the mounting base 10 with rivets 18.
The tip of the introduction part 14 is placed sufficiently close to the folding roller group 1.

In the above configuration, if a paper jam occurs or during transportation, the bag 6
If it becomes necessary to remove the mounting screw 13,
The buckle 6 can be removed from the mounting base 10 by loosening it. Due to this removal, the introduction section 14
remains fixed by the fixing plate 5.

Also, attach the detached buckle 6 to the mounting base 10 again.
In order to attach the buckle 6, the lower end of the buckle 6 may be placed on the stepped portion 12 of the mounting base, and the buckle 6 may be fixed at that position with the mounting screw 13. Due to this, this buckle 6
It becomes possible to reliably attach it to the position it was in before it was removed. As a result of the above, even if the buckle 6 is removed or attached, the positional accuracy of the introduction part 14 is not impaired in any way.

(Effects of the invention) As detailed above, according to this invention, the positional accuracy of the paper introduction part of the buckle is not impaired in any way even when the buckle is attached and removed, so there is no decrease in folding accuracy. This has the effect of reliably preventing the problem.
