[Problems to be solved by the invention]
However, as in the technique described in Patent Literature 1, when managing a postal matter by reading only a continuous management number added to a postal matter, it is possible to detect that a specific management number has been lost and to manage the postal matter. Although work defects such as missing items or data skipping can be found, if you try to manage postal items due to differences in general or special processing categories depending on the area or delivery conditions, you will need to assign a continuous management number for each processing category. Unless it is necessary to clarify the correspondence between processing categories and control numbers, it is necessary to add postal codes to identify postal codes from control numbers and sort postal items to be conveyed according to the identified postal code divisions. There was a problem that can not be. Similarly, when acquiring the postal code associated with the management number from only the management number, for example, a management file that holds the correspondence between the processing category and the management number for each day is mistaken for another day. There was a problem that such mistakes could not be found.
[0005]
On the other hand, as in the technique described in Patent Literature 2, when managing postal items by reading the postal code itself attached to the postal item, a plurality of postal items with the same postal code are added to the postal item. There is a problem that it is not possible to find work defects such as missing data or data skipping.
Further, if the management number and the postal code in the destination data are to be read simultaneously from the postal matter to which the control number has been added, it is necessary to read two portions from the postal matter. Therefore, there is a problem in that the cost of the apparatus is increased to cope with the problem, and the work efficiency is reduced when one reading unit is used twice to read two portions.
[0006]
The present invention has been made in view of the above problems, and has as its object to provide a mail sorting apparatus and a mail sorting method that can easily and early perform sorting of mail and detection of work defects. And

Next, the operation of the present embodiment will be described with reference to the drawings.
FIG. 2 is a flowchart showing the operation of the mail sorting apparatus according to the present embodiment.
In FIG. 2, first, the matching processing unit 12 of the control unit 1 determines, from the delivery destination information database 11, the number of mails to which the postal code is added for each postal code included in the delivery destination information of the mail, A delivery destination information classification table indicating the association with a range of management numbers uniquely assigned continuously to delivery destination information arranged in the order of postal codes is read (step S1).
FIG. 3A shows an example of a delivery destination information classification table according to the present embodiment. The delivery destination information classification table includes delivery destination information arranged in the order of a postal code, the same postal code number, and a postal code. In addition to the association with the range of the management number that is uniquely assigned consecutively, the classification number assigned to the mail is stored for each mail processing content.
[0026]
When the delivery destination information classification table is read, the mail is loaded on the transport conveyor and transported while counting the number using the counter 2 (step S2).
Then, the management information added to the mail is read by the reader 3 arranged on the transport conveyor (step S3).
FIG. 3B shows an example of management information added to the mail to be conveyed in accordance with the delivery destination information classification table shown in FIG. 3A. The management information is shown in FIG. As shown in the figure, the postal code is stored in the delivery destination information classification table, and is composed of a series of numbers in which a management number continuously and uniquely assigned to the delivery destination information arranged in the order of the postal code is combined.
[0027]
Next, it is determined whether the management information of the mail is read by the reader 3 (step S4).
If the management information of the mail is read by the reader 3 in step S4 (YES in step S4), the collation processing unit 12 of the control unit 1 checks the count value (count result) of the number of mails for the mail. The management information read from the mail is checked against the delivery destination information classification table to check for a work defect such as a missing mail or skipped data and a zip code (step S5). It is determined whether the management information read from the mail by the reader 3 is correct management information expected from the counting result (step S6).
[0028]
If the management information is the expected correct management information in step S6 (YES in step S6), it is determined whether there is a designation to perform postal code sorting or serial number sorting (step S7).
In step S7, if there is a designation to perform postal code sorting or serial number sorting (YES in step S7), based on the delivery destination information classification table, (1) a change in postal code, (2) upper two digits of the postal code Two-digit sorting based on the same, (3) sorting of postal codes such as miscellaneous sorting, or number sorting based on management information and counting results (step S8).
Then, the print processing unit 13 instructs the marker printing machine 4 to print a different marker for each sorted mail (step S9), and the operator separates the mail based on the printed marker and distributes the mail. Turn to
[0029]
In step S7, if there is no designation to perform postal code sorting or serial number sorting (NO in step S7), the print processing unit 13 does nothing, and the worker directly sends the mail to delivery.
On the other hand, in step S4, when the management information of the mail is not read by the reader 3 (NO in step S4), or when the management information is not the expected correct management information in step S6 (NO in step S6). ), The print processing unit 13 instructs the marker printing machine 4 to print a marker on the defective mail (step S10), and the collation processing unit 12 stops the operation of the mail sorting device (step S11).
Thereafter, the operator corrects the data of the postal matter according to the delivery destination information classification table.
[0030]
As described above, the mail sorting apparatus according to the present embodiment arranges, for example, for each zip code included in the delivery destination information of the mail, the postal number to which the zip code is added and the zip code. A delivery destination information classification table indicating the association between the assigned delivery destination information and the range of the management number uniquely assigned to the delivery destination information is stored in the delivery destination information database 11, and the mail is conveyed while being counted while being read. The management information added from the mail conveyed by the machine 3 is read.
Then, the matching processing unit 12 of the control unit 1 compares the count result and the read management information with the delivery destination information classification table, and checks for a work defect such as a missing mail item or data skipping and a postal code check. It is determined whether the management information read by the reader 3 is correct management information expected from the counting result. Further, the print processing unit 13 controls the marker printing machine 4 to perform marker printing based on the collation result (judgment result).
[0031]
This makes it possible to acquire the postal code and the management number as management information at one time, eliminating the need to provide two readers 3 and performing the reading operation twice, thereby configuring the apparatus at low cost and sorting the mail. And the mail sorting operation can be performed easily and inexpensively.
In addition, according to the postal code and the management number included in the management information, it is possible to simultaneously check for work defects such as missing mail or skipped data and to sort by postal code, thereby improving the efficiency of mail sorting work. The effect is obtained.
[0032]
Further, a modified example of the mail sorting apparatus for obtaining the same effect will be described below.
As a modified example of the postal sorting apparatus, as shown in FIG. 4A, a postal code, the same postal code number, and a set of postal items to which the same postal code is assigned are included in the delivery destination information classification table. In addition to being managed independently for each postal matter, in addition to associating them with a continuous range of management numbers within the same postal code uniquely assigned to the delivery destination information in each set, the The assigned section number is stored.
Also, the management information corresponds to the delivery destination information classification table shown in FIG. 4A, and has the same postal code as the postal code stored in the delivery destination information classification table as shown in FIG. 4B. Is managed independently for each set of postal items to which the postal code is assigned, and is composed of a series of composite numbers of consecutive management numbers within the postal code uniquely assigned to the delivery destination information in each set.
[0033]
Further, as another modified example, as shown in FIG. 5, the management information corresponds to the distribution destination information classification table shown in FIG. It may be composed of a sequence that combines delivery destination information arranged in the order of postal code with a management number uniquely assigned continuously.
In addition, the sorting operation of the mail is not performed by the marker processing based on the collation result (judgment result) of the collation processing unit 12 by the print processing unit 13 and the marker printing machine 4, but the postal matter is put in a pocket provided on the conveyor for conveyance. The mail may be separated based on the collation result (judgment result) by a sorting device (not shown) that separates and accumulates the mail.
[0034]
【The invention's effect】
As described above, according to the present invention, the postal code indicating the delivery destination of the postal matter and the management number uniquely assigned to the postal matter are acquired at a time as the management information, and the acquired postal code and the management number are obtained. The mail can be sorted accurately on the basis of the mail.
Therefore, since the postal code and the management number can be obtained as the management information at one time, there is no need to provide two management information reading means or to perform the reading operation twice. And the mail sorting operation can be performed easily and inexpensively.
[0035]
In addition, according to the postal code and the management number included in the management information, it is possible to simultaneously check for work defects such as missing mail or skipped data and to sort by postal code, thereby improving the efficiency of mail sorting work. The effect is obtained.
Furthermore, when different markings are added to the sorted mail items when sorting the mail items, the effect that a mail sorting device can be realized at a low cost can be obtained, and the mail items into which the mail items are sorted can be obtained. If the objects are separated, the burden on the subsequent work is reduced, and the effect of improving the efficiency of the mail sorting work can be obtained.
