2. Description of the Related Art Conventionally, as a paper sheet processing apparatus, a route assembling machine for assembling a route for a mail item has been known. The route assembly machine accommodates a plurality of mail items and supplies the mail items to the predetermined take-out position one by one, a take-out unit for taking out the mail items fed to the take-out position, and the taken-out mail items. A reading unit that reads address information from the device, a conversion unit that converts the read address information into a preset route number, a sorting unit that sorts and collects mail items according to the route number, a take-out unit, a reading unit, and And a transport path extending through the sorting / collecting unit. The sorting / collecting unit has a plurality of sorting pockets along the conveying path, and all the mail pieces are sorted into predetermined sorting pockets according to the route number.

When the postal items are rearranged by the route assembling machine thus constructed to assemble the route, it is necessary to supply the postal items to the route assembling machine a plurality of times according to the number of digits of the route number. For example, if a mail item is given a three-digit route number, the mail item must be fed to the route assembler at least three times.

In the first supply, the mail information taken out by the take-out section has its address information read by the reading section, and this address information is converted into a route number by the conversion section. Then, the mail items are sorted and collected in a predetermined sorting pocket according to the first digit of the route number.

And are connected.

Next, the operation of the route assembling machine 1 configured as described above will be described. Before that, as an example of the route assembling method of the mail, for example, a route assembling machine having 10 division pockets (other configurations are the same as the above-described route assembling machine 1) is used to randomly arrange 1000 items. A method of rearranging ordinary mail items according to the route will be described with reference to FIGS. 4 and 5. In this case, the address information attached to the postal matter is the three-digit decimal number (000-9
99) and the mail is fed to the route assembler three times for sorting.

As shown in FIG. 4, in the first supply, mail items with 1's place of 0 are accumulated in the leftmost division pocket (1) according to the 1's place of the route number, and the next division pocket. Mail items with 1's place are accumulated in (2), and ... Mail items with 1's place are accumulated in the rightmost sorting pocket (10). Then, after the first supply is completed, all the mail pieces are transferred by the transfer mechanism 30 without changing the order thereof.
Transfer to.

In the second feeding, the mail items are sorted and accumulated in the sorting pockets (1) to (10) in the same manner as in the first feeding described above in accordance with the tens digit of the route number and are fed without changing the order. Transferred to Part 2. Then, in the third supply, in accordance with the 100th place of the route number, as in the first and second supply described above, each of the division pockets (1) to (1).
Sort and collect mail items to 0). As described above, by supplying three times, all 1000 mail items are sorted in the order of the route number.

However, when the destinations of the mails are partially concentrated at an address, the corresponding division pockets may overflow and the mails cannot be route-assembled. Hereinafter, a case where one division pocket overflows will be described.

For example, as shown in FIG. 5, address information [3
2-1], when 100 mails are concentrated at the address,
When the route number [002] preset according to this address is distributed to the 100 mail items, the route number [002] is added to all 100 mail items. As a result, in the first supply, the number of postal items having the first digit of the route number of 2 exceeds 100, and overflow occurs in the third sorting pocket (3), so that the postal items cannot be route-assembled.

Therefore, when overflow occurs in the sorting pocket (3), the route assembly of the mail is stopped and the mode is switched to the pre-supply mode. That is, when the switch 45 of the overflow pocket (3) is actuated and the overflow is determined, only the address information is read from the postal matter taken out by the takeout section 4 and the RAM 50 is read.
Buffered in. Then, the mail items whose address information has been read are sequentially accumulated in the vacant sorting pockets. The pre-supply mode described in the detailed description and claims of the invention is a mode in which only the address information is read in advance from all the mail items before the route assembly of the mail items is started and the address information is buffered. And the ROM 43
It is stored as control data in the.

When the address information of all mails is buffered and the pre-supply is completed, a new route number (section number) considering overflow is set based on this address information. It should be noted that this route number is set in consideration of overflows in the second and third supply.

For example, in the example shown in FIG. 5, 100 pieces of mail having address information [3-2-1] are [00
3] to [101] are given consecutive new route numbers. As a result, mail is not concentrated in one sorting pocket, and overflow is prevented.

Then, according to the new route number, all the postal items are supplied to the route assembly machine 1 three times (main supply) to complete the route assembly of the postal items. If the postal matter does not overflow in the sorting and accumulating unit 20 in the first supply, the first supply is continued without switching to the pre-supply mode, and then the second and third supply is performed. .

Next, based on the above-mentioned route assembling method,
The route assembling operation of the route assembling machine 1 of the present invention will be described with reference to the flowchart shown in FIG. Note that the address information recorded on the first side of each mail is a three-digit route number (serial number) based on the 12-decimal system prepared in advance according to the number of classification pockets 22 (12 excluding reject pockets). To be converted.

First, as shown in step 1, the supply unit 2
The moving mechanism 2a supplies a plurality of (for example, 1000) pieces of postal matter stored in the supply unit 2 to the predetermined take-out position one by one, and starts the first supply. The postal matter supplied to the take-out position is taken out by the take-out section 4 and conveyed on the conveying path 3 and is provided on one side of the conveying path 3, that is, on the side facing the first surface of the conveyed postal matter. It is guided to the scanner 6.

Then, as shown in step 2, the scanner 6 reads the address information recorded on the first side of the mail, the address information is buffered in the RAM 50, and a preset three-digit route is set. Converted to a number.

The postal matter whose address information has been read by the scanner 6 is guided to the reversing mechanism 8, where the direction of the conveying direction is changed by 180 ° by the direction changing section 8a, and the conveyance standard is adjusted by the aligning section 8b, and then the mail is conveyed. And is guided to the sorting and accumulating unit 20.

Further, the postal matter whose address information cannot be read by the scanner 6 is guided by the switching gate 14 and is rejected to the rejection stacking unit 10. The rejected mail pieces are sorted and collected manually in predetermined sorting pockets 22 after the first supply of all the mail pieces is completed.

The postal matter guided to the sorting / collecting unit 20 is sorted and stacked in a predetermined sorting pocket 22 based on the first digit of the route number, as shown in step 3. That is, the switching gate 24 that communicates with the sorting pocket 22 corresponding to the first digit of the route number is switched, the sorting conveyance path 21 is communicated with the predetermined sorting pocket 22, and the mail items are sorted and collected in the predetermined sorting pocket 22. It

During the sorting operation, each sorting pocket 2 is always
Go to switch 45 provided in 2 and step 4
As shown in, it is determined whether or not there is a compartment pocket that has overflowed.

As a result of the judgment shown in step 4, when an overflow occurs in one partition pocket 22 during the first supply, as shown in step 5, the pre-supply mode is switched to stop the sorting operation. If the result of determination is that overflow does not occur in all sorting pockets 22, the supply of mail is continued, all mail is sorted and accumulated, and as shown in step 6, the first supply is completed. .

An overflow occurs in one section pocket 22 and the mode is switched to the pre-supply mode (step 5).
Then, as shown in step 7, only the address information is read from all the mail pieces, the address information is buffered in the RAM 50, and as shown in step 8, the pre-supply is completed.

When the pre-feeding is completed, all the mail pieces are moved by the rotating mechanism 36 of the transfer mechanism 30 into the respective compartment pockets 22.
Bottom plates 32a and 32b are rotated to the positions indicated by broken lines in the figure, and the mail pieces in the respective compartment pockets 22 are transferred to the supply section 2 without changing the order thereof, and as shown in step 9, the first supply preparation Is done. Then, the mail items are sorted based on the first digit of the route number as in step 3, and the first supply of all the mail items is finished as in step 6.

When the first supply of all the mail items is completed as described above, the transfer mechanism 30 transfers the mail items in each sorting pocket 22 to the supply unit 2 without changing the order. As shown in step 10, the second supply preparation is performed.

Then, as shown in step 11, the mail items are sorted and collected based on the second digit of the route number. When the second supply is completed as shown in step 12, all the mail pieces are transferred to the supply section 2 by the transfer mechanism 30 in preparation for the third supply as shown in step 13.

Finally, as shown in step 14, the third sorting operation is executed in the same manner as the first and second sorting operations described above, and all the mail pieces are sorted into the predetermined sorting according to the third digit of the route number. Collected in pockets, step 1
As shown in 5, the third supply is completed. As a result, all the mail items are rearranged in the order of the route numbers, and the route assembly of the mail items is completed as shown in step 16.

As described above, the route assembling machine 1 according to the embodiment of the present invention switches to the pre-supply mode only when an overflow occurs in the sorting / collecting unit 20 in the first supply of mail items. In most cases pre-feeding is unnecessary. For this reason, unlike the conventional route assembly machine, it is not necessary to perform pre-supply each time, and the processing time required for route assembly is shortened. Further, the jam occurrence rate is reduced as the processing time is shortened. Further, by omitting the pre-feeding, the number of times the postal matter is fed to the route assembling machine can be reduced, so that the pain of the postal matter can be minimized. The present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention.
