Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet conveying device for conveying mail items sorted by a sorting machine, for example.

In recent years, various automatic mail processing machines have been put into practical use in order to save labor in postal operations, one of which is the automatic postal code reading and sorting machine that automatically reads postal codes and automatically sorts them by address. be.

Conventionally, in this type of device, the collected mail in a group of stacking boxes arranged in multiple stages in the vertical direction is manually taken out by an attendant in each stacking box, and the collected mail is It is now possible to put a destination card on it and bundle it together. Therefore, dedicated staff must be stationed at all times.
Moreover, there was a problem in that the staff had to move over a wide range, which placed an extremely heavy burden on them.

Therefore, in recent years, automatic take-out devices have been installed which can automatically take out the mail items sorted and accumulated in the collection box group and sequentially transfer them to the next process, the destination card attaching device section and the bundling device section. A sorting machine has been developed.

By the way, this sorting machine with an automatic pick-up device requires strict adherence to the amount of items to be processed and the bundling time (for example, in order to prevent late delivery of mail and maintain trust, mail that arrives at 8 a.m. must be processed by 11 a.m.). (There are regulations regarding mail processing that must be completed.) Due to other unavoidable circumstances, the mail may be taken out to the transport path and transported to the bundler section before the predetermined number of mail items are stacked in the collection box. In this case, even if the mail is bundled with the normal binding force depending on its height, the number of mail items is small and the items may become bent or damaged, so the binding force must be weakened. However, there was an inconvenience that the mail would fall apart.

The present invention has been made focusing on the above circumstances,
The purpose of this is to ensure the bundling of paper sheets by transferring those whose stacking amount is less than a predetermined amount from the paper sheets transported by the transport path to the stacking section. Another object of the present invention is to provide a conveyance device for paper sheets that is capable of automatically transferring paper sheets to a conveyance path when the amount of paper sheets accumulated in the stacking section exceeds a predetermined amount.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1 in the figure is a sorting machine, and this sorting machine 1 sorts and collects postal items such as postcards and envelopes into sorting collection boxes based on the postal code as sorting information, and when the appropriate amount of mail is sorted and collected. It is extruded to the rear conveyance path 2 by an automatic extrusion mechanism (not shown). Further, on one side of the conveyance path 2, a plurality of stacking sections 3... are disposed at predetermined intervals, and on the other side of the conveyance path 2, the stacking sections 3... In a state where multiple transfer mechanisms 4...
...is provided.

The moving mechanism 4... and the accumulation section 3... are the third
It is configured as shown in the figure. That is, the moving mechanism 4 is constituted by a rod 5 provided to be able to freely reciprocate and an extruder 6 attached to the tip of the rod 5.

Further, the stacking section 3 has a receiving plate 8 movable upwardly and downwardly within its casing 7, and this receiving plate 8 is connected to a drive belt 10 via a connector 9. The drive belt 10 is spanned between a pulley 12 of a drive motor 11 and a driven pulley 13 provided above the pulley 12, and is configured to run in forward and reverse directions. Furthermore, detectors 14, 14, and 15 are arranged on both sides and the lower part of the stacking section 3. A predetermined amount of mail A accumulated in section 3 is detected. Further, the stacking section 3 is provided with a return mechanism 16. The return mechanism 16 is comprised of a rod 17 that is reciprocally movable and a push-out plate 18 attached to the tip of the rod 17. This return mechanism 16 is adapted to operate when a predetermined amount or more of mail A is accumulated in the accumulation section 3.

Further, a bundle section 19 is provided in the middle of the conveyance path 2, and a paper bill transfer section 20 is provided on the carry-in side of this bundle section 19.

In the above-described configuration, when the sorting machine 1 sorts and accumulates the mail and a predetermined amount of mail is accumulated in the sorting and accumulating box, the mail is automatically transferred from the sorting and accumulating box to the transport path 2.
is extruded. The mail A pushed out to the conveyance path 2 is conveyed by the travel of the conveyance path 2, and if it is stacked a predetermined amount, it is conveyed as it is and a paper bill is placed on the top surface by the paper bill transfer section 20. , After that, they are bundled by the bundler 19 and transported to a predetermined location.

On the other hand, during this transportation, due to strict adherence to the collection time or other unavoidable circumstances, the mail A may be pushed out to the transportation path 2 before the predetermined amount of mail A is accumulated in the sorted collection box. A small amount of mail group A is transferred from the transport path 2 to the stacking section 3 by a predetermined transfer mechanism 4. When this mail group A is transferred, the amount of the transferred mail is detected by the detectors 14 and 1.
4, and the receiving plate 8 is lowered by the operation of the drive motor 11 by an amount corresponding to the transferred amount. This transfer is repeated several times, and when the receiving plate 8 is lowered to a predetermined position and the accumulated amount of mail group A exceeds a predetermined amount, it is detected by the detector 15, and the drive motor 11 is driven in reverse. The receiving plate 8 is raised to the same level as the conveyance path 2, and at this time the return mechanism 1
6 operates to push out the mail group A to the conveyance path 2 again by its pushing plate 18. This mail group A is sent to the paper bill placement section 20, where paper bills are placed thereon, in the same manner as described above, and is also sent to the bundling section 19 where it is bundled.

As explained above, in the present invention, among the paper sheets conveyed by the conveyance path, those whose stacking amount is less than a predetermined amount are transferred from the conveyance path to the stacking section by the transfer mechanism. All of the paper sheets conveyed to the stacking section are stacked in a predetermined amount, so that the paper sheets can be bundled reliably. In addition, when the amount of paper sheets accumulated in the stacking section exceeds a predetermined amount, the return mechanism returns them to the conveyance path, which eliminates the need for workers to take the trouble to collect paper sheets from the stacking section, improving work efficiency. It has the effect of being superior.
