Abstract

PURPOSE:To reduce the labor of an operating person and enhance the efficiency of operation of a paper handling device, by using a send-out mechanism so that paper on a table is automatically sent out therefrom. CONSTITUTION:Paper 3 discharged from a printer 1 goes to a paper handling device 4 through a tractor 2, and is folded on the rest 12 of a paper guide 7 through between cutter rollers 5 and feed rollers 8 by piling blades 10. After some work, the paper 3 is cut off along a perforation by a cutter. A discharge mechanism 12A is then driven to discharge the cut-off paper 3 onto a table 14. When a prescribed quantity of the paper 3 is accumulated on the table 14, the paper discharge belt 18 of a paper send-out means 45 is operated and a guide plate 19 is moved, so that the paper 3 is sent out from the table while being guided by the plate 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper processing device that loads, folds, cuts, and feeds sheets of paper continuously discharged from a printer onto a table and out of the table.

As a conventional paper processing apparatus of this type, there is one shown in FIG. 1, for example.

In the figure, 1 is a printer, and the paper 3 that is continuously ejected from this printer 1 according to the job is the tractor 2 of the printer 1.
and sent to the paper processing device 4. In the paper processing device 4, the paper 3 is first bitten by the cutter roller 5, guided by the feed roller 8 of the paper guide section 7, bitten by the feed roller 8, and then swung and rotated according to the length of the paper 3 and the feeding N of the paper 3. By swinging the fins 9 from side to side, the sheets are correctly folded and stored on the three-sheet tray 12 by the pile fins 10.

When the printing of one job is completed, the feeding of the paper 3 is temporarily stopped when the perforation of the last printed page of the job reaches the cutter part 6. When the paper processing device 4 receives the cut command, the cutter 6 is driven and the feed roller 8 is also driven. After the cut paper 3 is sent out onto the pedestal 12 by the feed roller 8, the discharge mechanism 12A is driven by the microswitch 11 for descending instructions, and the paper 3 is discharged onto the table 14.

As soon as the ejection mechanism 12A is opened and the paper 3 is ejected onto the table 14, the pedestal 12 is raised to the position of the upper limit detection micro switch 3, and when the upper limit is detected, the upward drive of the pedestal 12 is stopped and the ejection mechanism 12A is closed. When it is detected that the ejection mechanism 12A is closed, the paper processing device 4
notifies printer 1 that it is now possible to resume paper feeding. When the above operations are repeated, sheets 3 accumulate on the table 14. Then, it is detected by the table lowering detection photosensor 16, the table 14 gradually lowers, and the lower limit state is detected by the lower limit detection microswitch 15.

After confirming that the table 14 has reached the lower limit position, the operator pulls the table 14 out of the paper processing device 4 and takes out the paper 3.

However, in the conventional paper processing device 4, if the operator does not take out the paper 3 from the table 4, the paper holder 12 and the table 14 will be full of paper 3, and the paper processing device 4 will operate. This resulted in requests for operator intervention, reducing operational efficiency.

The present invention eliminates the above-mentioned conventional drawbacks by providing a mechanism for automatically sending paper on the table out of the table, and by providing means for controlling this mechanism, reducing the burden on the operator, and The purpose of the present invention is to provide a paper processing device that improves operational efficiency. Specifically, it includes a paper guide unit that attaches paper continuously fed from the printer, folds the paper, cuts the paper into bins at predetermined locations, and discharges the paper, and a table that stores the discharged paper. It is an object of the present invention to provide a paper processing device comprising a paper delivery mechanism that automatically discharges the stored paper to the outside of the table.

The details of the present invention will be explained below based on the drawings.

In the following description, parts that are the same as or similar to those of the prior art will be denoted by the same reference numerals, and redundant description will be omitted.

FIG. 2 is a diagram showing an embodiment of the present invention. In the figure, 40 is a paper processing device related to Himi 8AK, 45 is a paper feeding mechanism,
A discharge belt 18 for discharging the paper 3 accumulated on the table 14, a guide plate for guiding the paper 3 when discharging the paper 3] 9, a micro switch 17 for detecting the end of the guide plate 19; Micro switch 20. The sensor 21 is provided at the lower part of the paper guide section 7.

The paper 3 ejected from the printer 1 passes through the tractor 2 to the paper processing device 4, passes through the cutter roller 5 and the feed roller 8, and is folded onto the pedestal 12 of the paper guide section 7 by the pile fin 10. .

Upon completion of the job, the paper 3 is cut at the perforations by the cutter 6, and this is confirmed by the photo sensor 21 for paper cutting confirmation. Then, the ejection mechanism 12A is driven and the paper 3 is ejected onto the table 14.

The table 14 descends depending on how much paper 3 accumulates.
When the lower limit is detected by the lower limit detection microswitch 15, the ejection belt drive motor 26 (not shown in FIG. 2) is driven to operate the paper ejection bell (18) and at the same time drive the guide plate. A motor 30 (not shown in FIG. 2) is driven in the feed direction. Paper 3 is sent out,
When the end of the guide plate 19 is detected by the microswitch 17 for detecting the end, the ejection operation of the paper 3 is stopped and the guide plate drive motor 30 is driven in the retracting direction.

When the starting edge of the paper guide plate 19 is detected by the microswitch 20, the drive of the guide plate drive motor 30 is stopped, and the table 14 is then moved to the position detected by the table lowering detection photosensor 16. raise.

FIG. 3 is a block diagram of one embodiment of the present invention shown in FIG. 2, and the control of the sheet feeding operation in the above embodiment will be explained.

When the lower limit of the table 14 is detected by the lower limit detection microswitch 15, a pulse signal is generated in the differentiating circuit 23, and the discharge belt drive flip-flop 24 and the guide plate delivery direction drive flip-flop 27 are set. The outputs of these seven lip-flops 24 and 27 operate the discharge belt drive circuit 25 and guide plate drive circuit 29, and drive the discharge belt drive motor 26 and guide plate drive motor 30, respectively.

Next, when the end of the guide plate is detected by the microswitch 17 for detecting the end of the guide plate, the discharge belt drive flip-flop 24 and the guide plate feed-out direction drive flip-flop 27 are reset. Thereafter, the guide plate retraction direction drive flip-flop 28 is set, the guide plate drive motor 30 is driven in the opposite direction, and the guide plate 19 is retracted into the table 14. When the guide plate start end detection microswitch 20 detects the start end of the guide plate 19', the guide plate retraction direction drive flip-flop amplifier 28 is activated.
is reset, the drive of the guide plate drive motor 30 is stopped, and the -stroke is completed. During this time, the operator's intervention is highly required.

Since the paper processing apparatus according to the present invention is as described above, it has the great effect of reducing the burden on the operator and providing a paper processing apparatus with high operational efficiency.
