Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stacking mechanism of a paper sheet sorting device.

Conventionally, paper sheets accumulated in the accumulation chamber of a sorting device are manually taken out for subsequent processing.
This manual intervention reduces the processing capacity of the sorting device.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a paper sheet stacking mechanism that automatically takes out paper sheets stacked in a stacking chamber by a machine in order to improve sorting performance.

The invention will now be described in detail with reference to drawings of embodiments of the invention. FIG. 1 is a diagram showing an embodiment of the present invention, in which five accumulation chambers A, B, C, D, and E are provided. FIG. 1 is a view from above, and in the figure, paper sheets 1 are being carried in through the carry-in path 12.
Let us explain by showing the case where is accumulated in accumulation chamber A. The paper sheet 1 is drawn in by a switch and a drawing belt 5 located at one end of the accumulation chamber A,
Further, it enters the accumulation chamber 4 using the support member 3 as a guide.
At this time, a side plate 7 is provided so that the paper sheets 1 are aligned, and the movement of the drawn paper sheets is stopped. A support member 6 is provided opposite the support member 3 with the paper sheet 1 in between, and moves in the direction of the arrow on the support member 6 each time a paper sheet 1 is inserted. At this time, in addition to the movement of the support member 6, if a transfer belt 14 is provided on the bottom of the stacking chamber 4 and is driven, the sheets can be moved more easily.

The support members 3 and 6 are both connected to a drive mechanism (not shown) through the guide hole 2, and are connected to the loading path 1.
When inserting the paper sheet 1 from 2, the support member 3 does not move. Details of the installation of the support member 3 are shown in FIG. In FIG. 2, a is a top view and b is a side view. a
In this case, the relationship is set so that the retraction belt 5 slightly protrudes toward the accumulation chamber side from the support member 3. For this reason, as shown by b, the support member 3 has a notch 3a in which the belt 5 and rollers 5a can be accommodated.

When a predetermined amount of paper sheets is accumulated between the support members 3 and 6, the support members 3 and 6 sandwich the paper sheets and carry them to a take-out side 13 provided at the other end of the accumulation chamber A. At this time, by driving the bottom surface transfer belt 14, the material can be more easily transported to the take-out side 13. As for the predetermined amount to be accumulated, a detector that detects the amount of paper sheets may be used. If the predetermined amount to be stacked is the amount that occupies the stacking chamber A, the stacked sheets are sandwiched between the supporting members 3 and 6 as described above and sent to the take-out side 13; If it is full, the support member 3 will not move after all,
Only the support member 6 is moved to the take-out side 1 according to the amount of paper sheets.
It will move to 3. On the extraction side, there are vacuum suction chambers 11 corresponding to the respective accumulation chambers A to E,
Surrounding it is an endless perforated belt 10.

When the supporting members 3 and 6 sandwich the sheet of paper or when the supporting member 6 alone reaches the endless perforated belt 10, the supporting member 6 moves into the supporting member lifting hole 8.
It will come directly above. Then, a detector (not shown) detects this, stops the movement of the supporting members 3 and 6, and further lifts the supporting member 6 by a lifting mechanism (not shown) to ensure that the upper surface of the supporting member 6 is aligned with the surface of the substrate 9. lower it until it does. As the support member 6 descends, the paper sheet 1 is sandwiched between the support member 3 and the endless perforated belt 10. Therefore, the belt 10 is driven to periodically drive the vacuum suction chamber 11 corresponding to the accumulation chamber 4 into which the support member 6 has descended, and the support member 3
By applying pressure to the paper sheets 1 by
The belt 10 makes it possible to take it out.
If there is a transfer belt 14 on the bottom surface, pressure is applied by this belt 14 as well as the support member 3.

Figure 3 shows an example of take-out, where a is a top view and b is a top view.
is a side view. FIG. 1A is the opposite direction to that in FIG. 1, and FIG. 1B is a side view seen from the inside of the accumulation chamber. In b, the dashed-dotted line indicates the lowered support member 6.

In FIG. 1, for example, when paper sheets from the stacking chamber C are taken out, the supporting members 6 of the stacking chambers D and E are respectively moved to the vacuum absorption chamber 11 side and are kept in a state where they do not fall, and the belt 10 and the supporting member 6 are moved to the vacuum absorption chamber 11 side. Accumulation room C between
It is used as a conveyance path when taking out paper sheets.

The above-described invention of the stacking mechanism makes it possible to mechanically take out the stacked paper sheets from the stacking chamber of the sorting device, thereby improving the performance of the sorting device.

Claims (1)

[Claims] 1. A paper sheet carrying-in path, a drawing belt that pulls paper sheets from the carrying-in path, a stacking chamber having one end on the drawing belt side for stacking the paper sheets pulled in by the drawing belt, and the stacking chamber. It is equipped with two support members that hold the paper sheets that are drawn in and stacked in an upright position, and a take-out means that is provided at the other end of the accumulation chamber and consists of a perforated belt for taking out the paper sheets and a vacuum suction chamber. As the amount of paper sheets drawn in and accumulated by the drawing belt increases, one of the two support members on the side of the take-out means moves toward the take-out means side, and moves to the side immediately before the perforated belt. 2. A mechanism for accumulating paper sheets, characterized in that the other support member is moved toward the take-out means when the paper sheets are taken out by the take-out means.
