Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sorter, and more specifically, a sheet is pressed against a conveying belt by a pressing sheet, and the sheet is conveyed along the opening of a sorter bin. The present invention relates to a sorter that sequentially distributes data to each sorter bin using an indexer.

[Conventional technology]

Conventional sorters use a pressure sheet made of an insulating sheet such as a polyester sheet or Mylar sheet to press the recorded paper sent from the copier main body onto a conveyor belt made of rubber or the like, and then press the paper. There is a system in which the liquid is conveyed along the opening of the sorter bin and sequentially distributed to each sorter bin by an indexer.

By the way, in such a conventional sorter,
Due to static electricity generated while the paper is being conveyed, the paper is often electrostatically attracted to the pressure sheet, thereby making it impossible to convey the paper.

[Purpose of the invention]

This invention was made in view of the above circumstances,
It is an object of the present invention to provide a sorter that eliminates static electricity that tends to occur during the conveyance of paper, thereby avoiding a situation where the paper is electrostatically attracted to a pressure bonding sheet before reaching an indexer and becomes unable to be conveyed. .

[Structure of the invention]

In order to achieve the above object, the present invention presses a sheet of paper against a conveyor belt with a pressure-bonding sheet, slides the surface of the pressure-bonded sheet by frictional engagement with the conveyor belt, and conveys the paper to the opening of a sorter bin. The sheets are distributed to each sorter bin by an indexer, and the crimping surface of the crimping sheet is made of a conductive material, and a means for grounding the conductive material is provided, and the crimping of the paper is performed by this grounding means. It is designed to remove electric charges existing on the sheet side surface.

〔Example〕

Hereinafter, a sorter according to the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

The sorter 1 of this embodiment includes a horizontal transport section 10, a vertical transport section 20, and a storage section 3.
It is composed of 0, etc.

Of these, the horizontal transport section 10 is composed of a conveyor belt 11, rolls 12, 12 around which the conveyor belt 11 is wound, pressure rolls 13, 13, 13, and guide plates 14, 14, 14, 14. Further, the vertical transport section 20 is
It is composed of a conveyor belt 21, rolls 22, 22 around which the conveyor belt is wound, an indexer 23, a drive section 24 that moves the indexer 23 up and down, a crimping sheet 25, and a grounding means 26. Of these, the drive unit 24 rotates the ball screw 24a with a motor 24b, thereby
Support part 24c screwed into ball screw 24a
It is configured to move up and down. Also, the support part 2
An end of the indexer 23 is fixed to 4c.

On the other hand, the above-mentioned crimping sheet 25 is made of a conductive metal sheet, one of which is attached to the support portion 24c.
The guide 25a is connected to the upper end of the guide 25a, and the other end is wound around the support shaft 25b. As the indexer 23 moves up and down, the portion of the crimping sheet 25 that is wound around the support shaft 25b is pulled out.
It is wound by a reverse means (not shown) installed at b. This reversing means may be configured to store a force for rotating the support shaft 25b clockwise by rotating the support shaft 25b counterclockwise when the indexer 23 is moved up and down using a spiral spring, for example. good. Further, the grounding means 26 is for grounding the crimping sheet 25, for example, by grounding the crimping sheet 25 via a support shaft 25b. As a result, the potential of the crimping surface 25c of the crimping sheet 25 is always maintained at the ground level.

On the other hand, the storage section 30 is composed of a plurality of sorter bins 32 partitioned by a plurality of inclined plates 31. These sorter bins 32 are opened toward the vertical transport section 20, and their inner parts are closed by a plate 33.
Note that the reference numeral 2 is a housing, 3 is a recorded paper sent from the main body of the copying machine (not shown), and 4 is an entrance for carrying the paper 3.

Next, the operation of the above-mentioned embodiment will be explained,
The configuration will also be explained in more detail.

In this sorter 1, the paper 3 carried in through the carry-in port 4 is guided to the horizontal transport section 10,
It is pressed onto the conveyor belt 11 by the roll 13 and sent to the vertical transport section 20 .

The paper 3 sent to this vertical transport section 20 is transferred to the crimping sheet 25 and the crimping sheet 2.
5 is pressed onto the conveyor belt 21 by a supporting roll 25d, and conveyed along the opening of the sorter bin 32. At this time, the surface 3a of the paper 3 on the pressure sheet 25 side is electrically grounded via the pressure sheet 25 and the grounding means 26, and the paper 3 is neutralized. Therefore, the situation where the paper 3 is electrostatically attracted to the pressure bonding sheet 25 before reaching the indexer 23 due to static electricity and becomes unable to be conveyed is eliminated as much as possible.

The paper 3 that has been neutralized in this manner is transferred to an indexer 23 located at the opening of a predetermined sorter bin 32.
and is smoothly accommodated in the sorter bin 32.

In the above embodiment, the crimping sheet 25 is made of a metal sheet, and the crimping surface thereof is a conductive surface. A crimping sheet of any material may be used.

Further, in the above embodiment, the grounding means is used to ground the crimping sheet 25 via the support shaft 25b, but the present invention is not limited to the above embodiment. It goes without saying that the crimping sheet 25 may be brought into contact with the brush and the crimping sheet 25 is grounded via this brush.In short, any means that can maintain the potential of the crimping surface 25c of the crimping sheet 25 at the ground level at all times is sufficient. The grounding means is not particularly limited.

〔Effect of the invention〕

As explained above, the sorter of the present invention eliminates static electricity that tends to occur during conveyance of paper by providing a pressure-bonding sheet whose pressure-bonding surface is made of a conductive material and a means for grounding the conductive material. (It can be said that static electricity itself does not occur), thereby avoiding the situation where the paper is electrostatically attracted to the pressure bonding sheet before reaching the indexer and cannot be transported, and thereby the paper can be reliably stored in the sorter bin. It has an excellent effect.
