Abstract

PURPOSE:To sort of the number of copies more than the number of bins by binding papers sorted to be received in the respective bins by a stapler to successively discharge the bound papers to a paper stock part. CONSTITUTION:The papers sorted to be received in the bins 2b of a sorter 2 are bound by a stapler 2d to be discharged to a paper stock part 5 by a discharge means 6. Therefore, when the sorting number of copies are more than the number of the bins 2b, the papers are sorted to be once received in all of the bins 2b and bound by the stapler 2d to be discharged to the paper stock part 5 and the residual papers are again sorted to be received in the respective bins 2b and bound by the stapler 2d to be discharged to the paper stock part 5. This operation is repeated. By this constitution, even when the sorting number of copies of the papers is at the most with respect to the number of the bins 2b, sorting processing can be performed.

Description

Detailed Description of the Invention (a) Industrial Application Field This invention is mainly used as an accessory to an image forming apparatus such as an electrophotographic copying machine, and is used to sort or fold paper on which images have been formed. Alternatively, the present invention relates to a paper processing device that performs a binding process.

(B) Conventional technology Conventionally, in this type of paper processing apparatus, a sorter is used to sort paper ejected from an image forming apparatus into a plurality of bins;
Some devices are known that are equipped with staples for binding sheets sorted into each bin.

(c) Since there is only a problem to be solved by the invention, the conventional paper processing apparatus of this type has the problem that it can only sort as many copies as there are bins.

This invention was made in consideration of the above circumstances, and is a paper processing method that enables sorting of more copies than the number of bins by temporarily docking the sorted paper from the bins to the paper stock section. It provides equipment.

(d) Means for Solving the Problems The present invention provides a paper processing device that is equipped with a sorter that sorts sheets ejected from an image forming device into a plurality of bins, and a stapler that binds the sheets sorted into each bin. a paper stock section installed between the forming device and the sorter;
A paper transport path that connects the paper output port of the image forming apparatus and the paper feed port of the sorter, a discharge means that takes out paper from the bin and discharges it to the paper stock section, and a movement means that sequentially moves each bin to the discharge means. The paper processing apparatus is characterized in that the paper sorted into each bin of the sorter is bound by a stapler and then sequentially discharged to the paper stock section.

Further, the present invention provides a paper processing device that includes a sorter that sorts sheets ejected from an image forming device into a plurality of bins, and a staple that binds the sorted sheets in each bin. a paper stock section and a paper folding section installed in the paper stock section, a paper transport path that connects the image forming apparatus and the sorter via the paper folding section, a discharge means that takes out the paper from the bin and discharges it to the paper stock section; A sheet of paper comprising a moving means for sequentially moving the bins to a discharge means, and after sorting the sheets folded in a paper folding section into respective bins of a sorter, they are stapled by a stapler, and then sequentially discharged to a paper stock section. It is a processing device.

It is preferable that the above-mentioned ejecting means ejects the paper in each bin to the paper stock section only when the paper is closed by the staple.

(e) Operation The sheets sorted into the bins of the sorter are bound by staples and discharged to the paper stock section by the discharge means.

Therefore, if the number of copies to be sorted is greater than the number of bins, the sheets are sorted into all the bins at one end, the sheets in each bin are stapled using staples, the sheets are then ejected to the paper stock section, and the remaining sheets are placed again into each bin. After sorting and binding with staples, the paper is discharged to the paper stock section. By repeating this operation, it becomes possible to sort sheets no matter how many copies there are for the number of bins.

is a scraping member that sequentially discharges the sorted sheets from the bins 2b to the sheet stock section 5 through the discharge port 2g.

FIG. 2 is a top sectional view of the main part of FIG. 1, in which 6a is a shaft that rotatably supports the scraping member 6, 6b is a motor that rotates the shaft 6a, and 7 is a shaft through which the scraping member 6 passes. 8 is a notch provided in the bottle 2b, and 8 is a notch provided in the bottle 2b.
A notch is provided for directly taking out the sorted sheets from b by hand, and the scraping member 6 is made of a flexible plate such as a rubber plate.

The main operations in such a configuration will be explained next.

First, in the electrophotographic copying machine 1, copied sheets are conveyed through the sheet conveyance path 4, and at the same time, the bins 2b of the sorter 2 are repeatedly raised and lowered from the position shown in FIG. 1 to sort the copy sheets. When the sorting operation is completed, the sheets in each bin are closed by the stapler 2b. Further, punching is performed by the punching device 2e as needed. When those processes are finished, bin 2
b rises to the position shown by the dashed line in Fig. 1, and the motor 6
b (Fig. 2) is driven, and the scraping member 6 starts rotating. As shown in FIGS. 3 to 7, when the scraping member 6 rotates, the bin 2b is placed in a position facing the discharge port 2g.
of paper is scraped out by the scraping member 6, and the paper is scraped out by the scraping member 6.
The paper is discharged to the paper stock section 5 via g. Bin 2b is lowered one by one and this operation is repeated,
All the closed sheets of the bin 2b are discharged to the stock section 5. Next, when the bin 2b descends and returns to the home position shown in FIG. 1, the above-described operation is repeated again. Therefore, even if the number of copies set in the electronic copying machine l is greater than the number of bins 2b, the paper sorting work can be performed without any inconvenience. Note that when the paper copied by the electrophotographic copying machine 1 is folded by the paper folding device 3, the copy paper is similarly conveyed from the electrophotographic copying machine 1 to the sorter 2 via the paper folding device 3. , sorting is performed in the same way as described above.

FIG. 8 is a flowchart comprehensively explaining the operation of this embodiment. If normal copying is set in step 101, the electrophotographic copying machine will copy the copy and the second paper will be transferred from the paper ejection port 1a. The paper is directly discharged to the paper stock section 5 via the paper transport path 4a (step 102). In step 101, if it is not a normal copy, that is,
When sorting, stapling, or punching is required, if the bin 2b has not returned to its home position (the position shown by the solid line in FIG. 1), the bin 2b is moved to its home position (step 104). ), the paper conveyance motor (not shown) is driven (Step 05)
. Then, when the paper folding mode is set (step 106), the paper folding device 3 performs a two-fold operation (steps 107, 108) or a half-fold operation (step 1).
09, 110) etc. are executed. In step 12, if the sort mode is not set, the paper folded by the paper folding device 3 is discharged to the top of the bin 2b via the paper feed port 2a of the sorter 2 (step +12
). If the sort mode is set in step 111, the bins 2b are raised one after another, sheets are discharged into each bin, and the sorting operation is executed (step +12). Then, the conveyance of the paper is stopped on -th (
Step If3) If the mode is in which the sheets sorted into the bin 2b are automatically stapled, that is, the auto stipple mode (step 114), the sheets sorted into the bin 2b are automatically stapled by the stapler 2d. (step 115), and when the operation of the stapler 2d is completed, the bin 2b rises to the position shown by the dashed line in FIG.
The sheets in the bins 2b are sequentially discharged to the sheet stock section 5 (step 117). Here, if the number of copies is larger than the number of bins, step l again.
The operations from 04 to 117 are repeated. Note that in step +14, if the automatic stipple mode is not in effect, the lifting operation of the bin 2b is prohibited. This is bottle 2b
This is because when unbound sheets are discharged to the paper stock section 5, the sheets fall apart. Therefore, if the sheets are not bound, the operator must insert his/her hand into the notch 8 (FIG. 2) and take out the sheets sorted into each bin 2b.

The settings for each mode in FIG. 8 are made using a keyboard (not shown) provided in the electrophotographic copying machine 1. Further, according to the above embodiment, the paper stock section 5
Since it is installed above the paper folding device 3 and the paper conveyance path 4, it is easy for the operator to take out the stocked paper and it is convenient to use.

(G) Effects of the Invention According to the present invention, there is provided a paper processing device that can sort sheets without any trouble even when the number of sheets is greater than the number of bins of a sorter, and the sheets bound by a stapler can be Once the paper is discharged to the paper stock section installed between the image forming device and the sorter, the worker can take out the paper from a position close to the image forming device, making it easier to perform continuous work and improving work efficiency. An excellent paper handling device is provided.
