Description

[Detailed Description of the Invention] The present invention relates to a processing device for paper sheets that are randomly conveyed in an upright position along a conveyance path, accumulate them, and then feed them to the next stage.

Conventionally, this type of processing equipment was disclosed in Utility Application No. 114789/1989 (
As in Japanese Utility Model Application No. 50-60780), the ends of the stacked paper sheets were cut back using a spiral roller or the like.

As shown in FIG. 1, the helical roller 7 is effective for turning only the lower end of the end of the paper sheet.

However, the lower end of paper sheets is cut back,
The top edge of the end is not cut back, and in the case of weak paper sheets such as airmail, subsequent sheets that are sent collide with the top edge of the end of the already accumulated paper sheets. There were problems such as jams occurring or paper sheets not being stacked correctly.

Therefore, an object of the present invention is to provide a paper sheet processing device that eliminates the above-mentioned problems.

According to the present invention, by installing a detector for detecting paper sheets being conveyed and a paper leaf end holding lever controlled by a signal from the detector in a conventional processing device, paper sheets can be processed easily. A paper sheet processing device is obtained in which the ends of paper sheets are reliably accumulated on the next feeding section side.

Next, the present invention will be described in detail with reference to the drawings showing an embodiment of the present invention.

FIG. 2 is a plan view of an embodiment of the present invention, and FIG. 3 is a perspective view thereof.

In FIGS. 2 and 3, reference numeral 1 indicates a substrate of a paper sheet processing apparatus, and an arm substrate 2 has a rotation center (not shown) near the starting end of a conveyance path 3, and a bearing (not shown) on the substrate 1. It is floated by an arrow A, etc., and is movable in the direction of arrow A, which intersects the direction in which paper sheets are conveyed, and moves according to the amount of paper sheets.

The conveyance path 3 includes rollers 4a, 4b on the arm substrate 2,
4C and transport bells) 5a and 5b.

Further, a sheet end holding lever 6 and a helical roller 7 are installed at the end of the conveyance path.

The paper sheet end holding lever 6 is driven by a drive device such as a rotary solenoid 8.

A detector such as an optical detector 9 is installed along the conveyance path.

The stacking unit 10 includes a movable stacking roller 11 installed on the arm substrate 2 , a stacking pressure detection switch 12 that detects the amount of rotation of the stacking roller 11 , and a guide plate 13 .

The supply unit 14 includes rollers 15a and 1 installed on the substrate 1.
5 b, 15 C1 supply belt 16, main vacuum chamber 17,
It is composed of a sub-vacuum chamber 18 and a pinch roller 19.

The sheets are conveyed in an upright position by conveyor bells 5a and 5b, conveyed by a collecting roller 11, and the leading edges of the sheets are aligned by a guide plate 13.

At this time, the leading edge of the stacked papers is detected by an optical detector 9, and the paper end holding lever 6 is rotated from the solid line position to the broken line position and pulled back based on the detection output of the detector 9.

This is to prevent the leading edge of the paper sheets from colliding with the paper end holding lever and to ensure that the paper sheets are stacked in the stacking section 10.

Next, when paper sheets are accumulated, the paper leaf end holding lever 6
It rotates clockwise, returns from the broken line to the solid line position, and holds the end of the stacked paper sheets on the supply section 14 side.

It is important to hold the ends of the sheets, since the collecting rollers press the leading ends of the sheets against the supply section 14.

At this time, the helical roller 7 is constantly rotating and serves to feed the lower end of the paper sheet toward the supply section.

Therefore, even in the case of weak airmail letters as shown in FIG. 4, both the upper and lower ends of the paper sheet can be completely turned back toward the supply section 14 by the helical roller 7 and the paper end holding lever 6. It is possible to reliably prevent paper sheets that are subsequently stacked from colliding with the upper ends of the ends of paper sheets that have already been stacked, thereby preventing a jam from occurring.

In this way, paper sheets are accumulated one after another, and when the accumulation pressure increases, the accumulation pressure detection switch (not shown) is activated, and the arm board 2 is moved to the right by the drive motor (not shown), and the accumulation pressure increases. Create new space.

Next, the stacked paper sheets are supplied to the next processing device by the supply belt 16 having an intake hole and the negative pressure of the main vacuum chamber 17.

As described above, according to the present invention, it is possible to reliably turn back the ends of even weak paper sheets such as airmail letters, and to provide a processing device that reliably stacks paper sheets.
