Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a sorter that sequentially collates sheets discharged from a copying machine into a paper tray.

Conventional technology Conventionally, in a sorter that continuously collates sheets ejected from a copying machine, if a paper jam occurs in the sorter body, a paper path is set to eject the paper carried into the sorter body out of the sorter body. There is something set up. In addition to this paper path, it is also known that a paper path is provided to allow insert paper to be inserted into the main body of the sorter, and an application has already been filed for a paper path that doubles as a paper ejection port and an insertion port. There are (for example, Jitsugyo)
659-158325).

In the above-mentioned application, switching fingers a and b that rotate independently from each other as shown in FIG. With finger a at position a' and finger b at position b', paper c advancing in the direction of arrow d is guided to insertion/ejection port e, and is ejected from the insertion/ejection port e to the outside of the sorter main body. When inserting the insert paper c' into the sorter body, set the switching finger b to the solid line position and move the insert paper c' inserted from the insertion/ejection port e to the horizontal transport means f.
It is configured to send to.

Problems to be Solved by the Invention However, since the conventional sorter described above requires two sets of switching fingers a and b, there is a problem that the mechanism for driving these fingers a and b is complicated and expensive.

This invention was made for the purpose of improving the above-mentioned problems.

Means and Action for Solving the Problems In order to achieve the above-mentioned object, this invention has the following objectives: copy paper conveyed from a copying machine to the sorter main body 1 via the paper inlet 1a, A collation function that sends insert sheets inserted into the sorter main body 1 to each paper tray 5 of the sorter main body 1 via the conveyance means 3 and 4, and a copy function that sends the insert sheets inserted into the sorter main body 1 through the paper inlet 1a from the copying machine to the sorter main body 1. In a sorter equipped with a discharge function for discharging sheets from the paper discharge port 7 of the sorter body 1 to the outside of the sorter body 1 without collating the sheets, the present invention is arranged near the paper insertion port 6 and the paper discharge port 7 and rotates in one direction. one drive roller 8 for the discharge paper and the insert paper, which are arranged opposite to each other on both sides of the drive roller 8, and guide the discharge paper and the insert paper to the outside of the sorter main body 1 and the above-mentioned conveyance means 3, respectively. The guide members 9, 10 and the driving roller 8 are provided.
The paper paths 13 and 14 for the discharge paper and the insert paper formed by It is an object of the present invention to provide a sorter characterized in that a fixed guide 11 for guiding the insert paper to the conveyance means 3 is provided between the sorters.

Embodiment An embodiment of this invention will be described in detail with reference to the drawings. In the figure, 1 is a sorter main body, and a paper inlet 1a is opened at the upper part of the side surface into which paper 2 discharged from a copying machine (not shown) enters. ing. The paper 2 that enters the sorter main body 1 through the paper entry port 1a passes through the horizontal transport means 3 and the vertical transport means 4, each of which is an endless belt, and reaches the entrance 5a of the paper tray 5 provided in multiple stages. The sheets are sequentially carried into each paper tray 5 by a collating mechanism (not shown).

On the other hand, in the upper part of the sorter main body 1, an insertion port 6 and a discharge port 7 for the paper 2 are arranged in parallel at a position close to the paper inlet 1a. Below the insertion port 6 and the discharge port 7, a roller 8 made of an elastic material such as rubber or sponge is provided so as to be rotated in the direction of arrow A, and a pair of fixed guides 9 are provided near the roller 8. , 10 are installed to face each other with the roller 8 in between. Further, a fixed finger 11 is installed below the roller 8. The fixed finger 11 has a substantially triangular shape, and its bottom surface is close to the top surface of the horizontal conveyance means 3, and the end on the side of the paper inlet port 1a is formed in an arc shape. A base portion of a switching finger 12 is rotatably attached to 11a. The tip side of this switching finger 12 protrudes toward the paper entry port 1a, and is at the solid line position in Figure 2 when papers are collated.
The paper 2 carried in through the paper entrance 1a can be transported to the vertical transport means 4 by the upper surface of the horizontal transport means 3.

In addition, if a paper jam occurs in the sorter body 1, the paper is rotated to the position shown in the imaginary line in FIG. It is now possible to switch. The paper 2 that has entered the first paper path 13 reaches between the fixed guide 10 provided below the discharge port 7 and the roller 8, and is discharged from the discharge port 7 to the outside of the sorter main body 1 due to contact friction with the roller 8. It's becoming like that.

On the other hand, when inserting the insert paper 2' during collation, it is sufficient to insert the insert paper 2' through the insertion slot 6. After passing between the guide 9 and the roller 8, the paper is sent to a second paper path 14 provided between the fixed guide 9 and the fixed finger 11 so as to intersect with the first paper path, and from this second paper path 14, the paper is fed horizontally. Directional conveyance means 3
and is inserted into the paper tray 5 via the vertical conveyance means 4.

Note that 15 in the figure indicates a paper guide provided below the insertion port 6 and the discharge port 7.

Effects of the invention As detailed above, this invention
A driving roller 8 for the ejected paper and the insert paper is provided near the ejection port 7 and rotates in one direction, and the ejected paper and the insert paper are guided on both sides of the drive roller 8 to the outside of the tray and to the conveying means 3, respectively. The guide members 9, 10 are arranged opposite to each other with respect to the drive roller 8 to provide a two-way paper path 13, for the ejected paper and the insert paper.
14 are formed to intersect below the drive roller 8, and a fixed guide 11 is provided between the intersection of each paper path 13, 14 and the conveying means 3, and the fixed guide 11 transports the insert paper to the conveying means 3. Since the two paper paths 13 and 14 intersect at only one point and do not have a common path, the insert paper does not pass through the other path between the paper insertion slot 6 and the conveyance means 3. Since there is no need to provide a separate switching mechanism to prevent the insert paper from entering erroneously, the structure of the switching mechanism can be simplified.

In addition, since the two paper paths 13 and 14 are formed to intersect with each other, two paper paths can be used in a limited space.
The curvature of the paper paths 13 and 14 on the two paths can be maximized, and on the downstream side of the guide member 9, the fixed guide 11 moves the insert paper from the intersection of the paper paths 13 and 14 on the two paths to the conveying means 3. Since the guide is designed to guide the insert paper, even if the insert paper is inserted under adverse conditions, such as when the insert paper is inserted diagonally or when the leading edge of the insert paper is folded, there is no possibility of paper jamming in the paper path 14. It never happens.
