Description

[Detailed Description of the Invention] The present invention relates to a paper holding device used in bins of collating machines, paper discharge trays of copying machines, and the like.

Conventionally, this type of paper holding device was mainly used in copying machines,
It is known to be installed in a bin of a collating machine (hereinafter referred to as a sorter) used in a printing press or the like. As an example, the sorter described in Japanese Patent Publication No. 55-11589 is equipped with rotatable paper pressers on the bin entrance side and on the bin end side, respectively, in order to prevent the copy sheets in the bin from floating up. A static eliminating brush is fixed between the paper pressers to eliminate static electricity from the copy paper. When using this sorter, the copy paper conveyed to the bin flips up the paper presser on the entrance side by the conveyance force, enters the bin while contacting the static elimination brush, and pushes up the paper presser on the end side of the bin. contained in a bottle.

However, in this configuration in which a large number of paper pressers, static eliminating brushes, etc. are installed in the copy paper conveyance path, the resistance applied to the conveyed copy paper increases, making it more likely to cause paper jams in the bin, and the static eliminating brushes are installed in a fixed manner. Because of this, there may be cases where the paper does not come into contact with the copying paper, which has the disadvantage that the transmission action is unstable.

The purpose of this invention is to solve these conventional drawbacks,
To provide a paper holding device having a simple structure and being inexpensive, capable of preventing copy paper sent into a sorter from floating up, preventing paper jamming in a bin, and reliably removing electricity from copy paper.

In order to achieve this purpose, the paper pressing device of the present invention is used in a paper storage shelf of a collating machine, a copying machine, a printing machine, etc., in which the paper pressing device is integrally attached to a support and this support. The present invention is characterized in that the support body and the brush-like static eliminating member are attached so as to be able to swing integrally.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the paper pressing device of the present invention will be described in detail below with reference to the drawings. The sorter shown in FIG. 1 has a plurality of bins 2 partitioned by a plurality of partition walls 1. A bent portion 1a is formed on the bottle end side of the partition wall 1 forming the lower wall of the bottle 2, and protruding ears 3 are provided on the bottom side of the upper partition wall 1 forming the upper wall of the bottle 2 on the bottle entrance side and the bottle end side. A paper presser member 5 is pivotably attached to the prong 3 by a mounting pin 4. A conveyor belt 7, a guide pawl 8, and a conveyor roller 9 are provided to convey copy paper 6 discharged from a copying machine (not shown) into the bin 2. A suction box 10 is arranged at the rear.

FIG. 2 shows a first embodiment of the paper pressing member 5.
is its front view, and b is its side view. The paper pressing member 5 is composed of a support 5a pivotally connected to the protrusion 3 and a static elimination brush 5b integrally fixed to the support. A hole 11 for inserting the pin 4 is provided at the upper end of the support body 5a. Support body 5a, static elimination brush 5
b, the pin 4 and the partition wall 1 are made of conductive material.

Next, the operation of the paper pressing member 5 in the sorter shown in FIG. 1 will be described in detail. Copy paper 6 discharged from a copying machine (not shown) is attracted to a conveyor belt 7 by a suction box 10 and conveyed downward along the conveyor belt 7.
When the copy paper 6 is conveyed by the conveyor belt 7 to the position of the guide pawl 8 corresponding to a predetermined bin 2, it is fed into the bin 2 by the conveyance roller 9 via the guide pawl 8. The copy paper 6 fed into the bin 2 is further moved to the back of the bin 2 while rotating the paper presser member 5 on the entrance side upward by the conveyance force of the conveyor roller 9, and moves the paper presser member 5 on the end side upward. After being rotated, it comes into contact with the bent portion 1a constituting the end of the bottle 2, stops, and is housed in the bottle 2. Since the paper holding member 5 is always in contact with the copy paper 6 when fed into the bin 2, when the paper holding member 5 of the first embodiment shown in FIGS. 2a and 2b is used in a sorter, During this time, the static eliminating brush 5b is always in contact with the copy paper 6, so that the copy paper 6 is always neutralized. Further, after the copy paper 6 comes into contact with the folded portion 1a and stops, the paper pressing member 5 rotates due to its own weight and pushes the copy paper 6 into the bin 2.
The copy paper 6 is pressed against the lower wall to prevent the copy paper 6 from floating up.

FIGS. 3a and 3b are diagrams showing a second embodiment of the paper pressing member 5. FIG. In the first embodiment of the paper pressing member 5 shown in FIGS. 2a and 2b, a support 5a is provided halfway from the attachment part of the paper pressing member 5,
The static elimination brush 5b sandwiched between the two parts a protrudes from the middle to the tip, but this second
In this embodiment, the charge eliminating brush 5b is sandwiched between the supports 5a from the attachment part to the middle of the paper presser member 5, and the charge remover brush 5b is made to protrude from the middle to the tip of the paper presser member 5. When the paper holding member 5 is installed in the sorter, the upper part of the support 5a facing the upper wall of the bin 2 is
It extends from the attachment part to the tip, and is formed in a comb-like shape from the middle to the tip.

In the paper pressing member of this second embodiment, the upper part of the support 5a extends to the tip of the paper pressing member 5, so that when a bendable material such as carbon fiber is used as the material of the static elimination brush 5b, Also, the distal end of the paper presser member 5 prevents the charge eliminating brush 5b from bending, thereby eliminating instability in the paper press action and the charge remover effect.

Note that when a strong material such as metal wire is used for the static elimination brush 5b, these problems do not occur even in the configuration shown in the first embodiment.

FIG. 4 is a diagram showing a third embodiment of the paper pressing member 5. In this embodiment, the static elimination brush 5b is sandwiched between the supports 5a from the attachment part to the middle of the paper pressing member 5, and the static eliminating brush 5b is made to protrude from the middle to the tip of the paper pressing member 5. The lower part of the support body 5a, which faces the lower wall of the bin 2 when the paper presser member 5 is installed in the sorter, extends from the attachment part of the paper presser member 5 to the tip. The lower portion of the support 5a may extend over the entire lower side of the static eliminating brush 5b. Alternatively, it may have a comb-teeth shape as shown in the second embodiment. The static eliminating brush 5
If it is provided on the entire lower side of the brush 5b, the tips of the static eliminating brush 5b will be held with an extremely small distance between them.

In this third embodiment, the tip of the support 5a directly contacts the copy paper 6, and the neutralization brush 5b is not interposed between the paper 6 and the copy paper 6, so that the paper press effect of the paper press member 5 is ensured, and the copy paper Depending on the charged state of the static electricity removal brush 5b, the charge may be larger if the tips of the static eliminating brush 5b are not brought into direct contact as shown in the first and second embodiments, but are spaced apart at an extremely small interval as shown in FIG. It has advantages such as the ability to eliminate static electricity.

As described in detail above, the paper pressing device of the present invention integrates the static eliminating member and the paper pressing member into a single member, which were conventionally installed separately to obtain a static eliminating function and a paper pressing function, and were an obstacle to paper conveyance. This reduces paper conveyance resistance and reduces paper jams, and since the static eliminating member is always in contact with or close to the paper, a stable static neutralizing effect can be obtained.Furthermore, the simple structure makes it easy to manufacture. This paper holding device has various advantages such as being inexpensive.

Note that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the utility model registration claims. As an example, in the above embodiment, the static eliminating member is a static eliminating brush, but the present invention is not necessarily limited to this. For example, the tip of the paper pressing member may be sharpened to have a static eliminating effect. Furthermore, although paper holding members are placed at two locations, one on the entrance side and the other on the end side of the bottle, it is not necessarily necessary to have two paper holding members, and depending on the size of the paper used, the angle of inclination of the bin partition, etc., it is sufficient to place only on the entrance side. In this case, there is an advantage that the resistance to conveying the paper due to the contact of the paper pressing member is further reduced.

Further, the paper holding device of the present invention is not limited to the sorter shown in the above-mentioned embodiments, but can be used, for example, in a copying machine,
Of course, it can also be applied to paper receiving trays in printing machines and the like.
