Description

[Detailed description of the invention] The present invention can be used, for example, in an automatic mail processing machine.
The present invention relates to a paper sheet temporary stacking device that temporarily stacks conveyed mail items by arranging them in an upright position.

1 and 2 show, for example, a conventional paper sheet temporary stacking device in an automatic mail processing machine. In the figure, reference numeral 1 denotes a buffer section for temporarily accumulating letters P in an upright position.
is provided to sequentially transfer the letters P brought in from the direction of the arrow a to the one-letter take-out device 4 side arranged in the direction of the arrow b, and also to remove the letters P.
The distal end thereof is aligned in the alignment section 5.

Since it is necessary for the buffer section 1 to carry in and process letters P of various sizes, such as regular letters and non-standard letters, the buffer section 1 has a space that is set according to the maximum size of the letters.

However, in Japan, when collecting New Year's mail, etc., a large amount of letters P are of almost constant size, so the buffer section 1 does not require the conventional space, and the space of the buffer section 1 is limited to the maximum size of the letters P. Because of this setting, the above-mentioned New Year's mail and other regular letters have a long travel distance and collide with the screw roller 2, or they engage with the screw roller 2 and are not fed, resulting in them being screwed as shown in Figure 2. This had some disadvantages, such as the Euroroller 2 tending to fall toward the front side.

The present invention was developed in view of the above circumstances, and its purpose is to provide a temporary stacking method for paper sheets that is suitable for keeping the size of paper sheets almost constant and stacking large quantities of small-sized items. The aim is to provide equipment.

The present invention will be explained below based on an embodiment shown in FIG. However, since the same reference numerals as in FIG. 1 indicate the same parts, the explanation will be omitted. In the figure, a rotatable guide body 11 is attached near the carry-in side of the buffer section 10. That is, one end of the guide body 11 is directly connected to a shaft 13a that projects above the floor 12 from a rotary solenoid 13 provided at the lower part of the floor 12, and is also used to carry paper sheets, such as letters P, into the buffer section 10. A detector 15 for detecting the size of paper sheets is arranged on the front conveyance path 14.

Next, the operation of the present invention based on the above configuration will be explained. When the letters P to be handled are a large amount of New Year's mail or small-sized items that are temporarily stored in the buffer section 10, the rotary solenoid 13 is driven to move the guide body 11 clockwise from the position shown by the solid line to the position shown by the dashed-dotted line. Rotate in the direction to position.

Next, when the letter P is supplied to a supply section (not shown), the letter P is fed into the entrance of the buffer section 10 via the conveyance path 14. At this time, the guide body 11 installed near the entrance of the buffer section 10 is located at the position shown by the dashed line and is designed to guide the letter P, so the letter P enters along the guide body 11. , it is possible to reach the spiral wire 3 while engaging with the screw roller 2. On the other hand, when large letters P with large dimensions are temporarily accumulated in the buffer section 10, by positioning the guide body 11 in advance at the position shown by the solid line, the screw roller 2 can be moved from the entrance of the buffer section 10 as in the conventional case. After that, it reaches the spiral wire 3.

Therefore, when a large amount of New Year's postal mail or a letter P of a certain size is discharged from the entrance of the buffer section 10, it may collide with the screw roller 2 and be bent, or the contact between the entrance and the screw roller 2 may occur. This makes it possible to reliably prevent inconveniences such as falling into the space between the objects.

In addition, the guide body 11 in one embodiment of the present invention
is always attached to the shaft 13a of the rotary solenoid 13, but it may be made removable. Further, the positioning of the guide body 11 is set in advance based on the size of the paper sheet P to be handled, but is not limited to this. For example, as shown in FIG. Part 1
A detector 15 for detecting the size of the paper sheet P is arranged on the front conveyance path 14 of the paper sheet P, and the guide body 11 is actually rotated via the rotary solenoid 13 in response to a detection signal, and is positioned. Alternatively, the same effect as described above can be obtained.

As explained above, according to the present invention, when paper sheets of a certain size and small size are temporarily stacked, they are guided by the guide body, so they collide with parts in the buffer section and are bent, or the paper sheets are not easily stacked. It is possible to reliably prevent defects such as falling down in the internal space, and also has an excellent effect without impairing the original temporary accumulation function.
