DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet sorting system used in, for example, a postal service or the like, for separating a plurality of sheets of mail, etc., which have been bundled and put into one at a time. The present invention relates to a sheet sorting control method and apparatus for sorting sheets and sorting them in a predetermined order (assembly of directions).

[0002]

2. Description of the Related Art In recent years, a mail sorting function has been provided which has a recognition function for reading a bar code attached to a mail or a character recognition function for reading address information such as a postal code, and automatically sorts and processes mail based on the address information. The device has been put to practical use. In such a paper sheet sorting apparatus for mails and the like (hereinafter referred to as "paper sheets"), a plurality of paper sheets in a jurisdiction delivery area which are carried from the outside are put together, and the paper sheets are inputted. In the separation and supply unit, the separation is performed one sheet at a time, and the sheets are sequentially sent downstream. Then, based on data (bar-coded) such as a postal code and an address number, the data is sorted into a plurality of sorting ports prepared on the downstream side according to a predetermined algorithm, and the sheet sorting operation is performed. ,
That is, a route assembling process is performed.

[0003] In the conventional route assembling process, conveyed paper sheets are grouped by delivery section unit or by delivery time unit, and are combined into one processing unit (hereinafter referred to as "unit").
The sorting operation is executed twice (that is, two passes) or more for each unit, and rearranged in a predetermined order (assembly of directions). In a mail sorting apparatus of such a system, for example, when a three-pass system is adopted, one-pass, two-pass
Assuming that the number of pass divisions is 20, 20 ×
20 = 400 delivery points can be stored.

In general, when one unit (delivery zone) is conventionally completed, when a preceding delivery zone 1 and a subsequent delivery zone 2 are adjacent to each other, as shown in FIG. A method has been adopted in which separate mouths are secured one by one and distributed to different mouths. This method
There is an advantage that the work after the pass is simplified because the delivery zone is divided in units of the division mouth.

[0005]

However, when the preceding delivery zone 1 and the later delivery zone 2 are adjacent to each other, the method of sorting the delivery zones into separate sorting ports requires a paper sheet in the sorting port of the preceding delivery port 1. Is distributed halfway and moves to the next delivery zone 2, as shown in FIG. 7, an empty portion is created between the delivery zone 1 and the delivery zone 2, and the efficiency of use of the division mouth is increased. Decrease. This is good when there is a margin in the number of divided ports, but causes a problem when there is no margin.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to share and effectively use divided ports when the number of divided ports is not sufficient, and to eliminate the sharing when there is enough to perform post-operation. The present invention is to provide a method and apparatus for controlling the sorting of paper sheets, which can simplify the method.

A second partition table prepared in advance, and the first partition table and the second partition table can be selected and used. Accordingly, when the sorting process is performed using the first sorting table, the sheets are stored in the sorting port in a state where the sheets are densely packed without forming a gap with the unit. In this storage state, although the work after the pass is troublesome, it is advantageous in increasing the use efficiency of the sorting port. On the other hand, when the sorting process is performed using the second sorting table, the use efficiency of the sorting port is reduced. Work can be simplified because all the paper sheets can be scraped out. As described above, in the present invention, the two methods can be properly used each time according to the situation.

Further, the paper sheet sorting control method of the present invention calculates a sorting port required in the preceding unit sorting operation and a maximum total sorting port number required in the succeeding unit sorting operation, and When there is room, the sorting operation is performed using the second partition table, and when there is no room for the number of sorting ports, the sorting operation is performed using the first partition table. As a result, the maximum total number of divisions is derived by calculation, and when there is room for the number of divisions, the division operation using the first division table, which is easy to perform after the pass, is performed. Although it is troublesome, the sorting operation using the first sorting table which can increase the use efficiency of the sorting port can be performed.

Further, the paper sheet sorting control device of the present invention comprises:
A reading unit that reads code data that is pre-assigned to sheets that are sequentially sent one by one; a plurality of sorting ports that can receive the sheets that have been read by the reading unit; A system control means for analyzing the read code data, performing a sorting operation (pass) for sorting the paper sheets to the sorting mouth based on the analysis result, and controlling a series of operations until a calculation of a route assembly is performed; In the case where the paper sheets are divided into delivery section units, a first section table in which a certain delivery section and the next delivery section are continuously allocated in one section, A second sorting table for providing a new sorting port adjacent to the sorting port without being shared with the sorting port, wherein when the sorting operation is performed, one of the first table and the second table is selected. It is characterized in performing Te. Accordingly, when the sorting process is performed using the first sorting table, the sheets are stored in the sorting port in a state where the sheets are densely packed without forming a gap with the unit. In this storage state, although the work after the pass is troublesome, it is advantageous in increasing the use efficiency of the sorting port.
On the other hand, when the sorting process is performed using the second sorting table, the use efficiency of the sorting port is reduced. Because you can scrape all the papers,
Work becomes easier. As described above, in the present invention, the two methods can be properly used each time according to the situation.

Further, the paper sheet sorting control device of the present invention calculates the number of sorting ports required for the sorting operation of the preceding unit and the maximum total number of sorting ports required for the sorting operation of the succeeding unit, and The system control unit further includes a determination unit that determines whether there is a margin in the number of divisions without using the division table, and the system control unit determines whether there is a margin in the number of divisions without using the first division table. The second
The partitioning operation is performed by using the partitioning table, and the partitioning operation is performed by using the second partitioning table when there is not enough room for the number of partitions without using the first partitioning table. It is. As a result, the maximum total number of divisions is derived by calculation, and when there is room for the number of divisions, the division operation using the first division table, which is easy to perform after the pass, is performed. Although it is troublesome, the first is to increase the efficiency of using the division mouth

The code analyzer 15 analyzes the postal code and the lot number of the destination from the barcode data, and specifies the destination information (BC value). In addition to the destination information, various programs and processing data executed in the system control unit 20 are stored in the memory 16, and a first sorting table created as needed for sheet sorting control. 21 and a second sorting table 22 are stored. Further, the first section table 21 and the second section table 22 each store a table in which a barcode is associated with a delivery area, a delivery location, and a section opening.

In each of the path operations including the first sorting operation (hereinafter, referred to as one-pass operation; hereinafter, also referred to as two-pass and three-pass), the route assembling operation unit 17 starts with a random operation. The paper sheets supplied in order are rearranged (assembly of a route) according to a predetermined algorithm, and when the sorting operation starts from one pass operation and ends the three pass operation, it is scheduled (or assumed). Can be reordered. Normally, in this processing, the delivery area of the paper sheet and each time to go to the delivery are summarized as one processing unit, and this processing unit is one unit (in the present embodiment, the “delivery area” is one unit). Therefore, in the following description, one unit is referred to as a “delivery zone”, and the respective delivery zones are distinguished by attaching reference numerals to the delivery zone 01 and the delivery zone 02, respectively.) Then, in the operation of the first pass, the entire route of one delivery zone 01 is assembled using the sorting table for the first pass. In the operation of the second pass, the entire delivery zone 01 after the operation of the first pass is completed
The directions are assembled using the sorting table for the pass, and in the operation of the third pass, the delivery zone 01 after the operation of the second pass is completed.

The system control unit 20 performs control operations of the entire system, such as barcode reading and analysis, various operations for assembling directions, and command transmission for drive control, which are necessary for sheet sorting. Also,
The system control unit 20, for example, when the delivery zone 01 completes the sorting operation of three passes and subsequently enters the sorting operation of the first pass of the delivery zone 02, calculates the maximum total sorting number required for the next sorting operation. Switching between performing the partitioning operation using the first partitioning table 21 and performing the partitioning operation using the second partitioning table 22, and performing the partitioning in a manner according to the table selected by the switching. Perform operation processing.

The operation of the sorting machine having such a configuration will be described below. The sorting machine in the present embodiment is a case where the sorting machine is implemented in three-pass route assembly. First, a mechanical part will be described. In this sorting machine, paper sheets in a delivery area selected by an operator are transported to the paper sheet supply unit 1, and the paper sheets are fed out by the paper sheet separation and supply device 9. When the operation of the first pass of feeding one sheet at a time from the position 8 toward the reading unit 2 is started, the reading unit 2 reads a bar code, that is, reads a postal code. The code data of the one sheet thus read is analyzed by the code analysis unit 15, and based on the analysis result, the system control unit 20 recognizes the postal code and the lot number information obtained by analyzing the bar code data. Then, based on this information, the division port 3 classified in one-pass operation
a is determined. Next, the system control unit 20 records the recognized postal code and the lot number information (BC value) and the sorting port data in the one-pass operation obtained by the determination operation in a one-pass log. Next, it is checked whether or not reading of all the sheets has been completed, and if not, the reading operation of the next sheet is performed. When all the sheets have been read, the one-pass operation of the sheet sorting control ends. When the sheet reading operation is completed in this way, the system control unit 20 creates the BC values and sorting port data for all the sheets. On the other hand, the paper sheets sorted by the code data are sent to the corresponding sorting ports 3a, respectively, and are sequentially accumulated in the corresponding sorting ports 3a. When the operation of one pass is completed, the sheets are transferred to the storage shelf 5 and stored while maintaining the state of being accumulated in each sorting port 3a. After the operation of the first pass is completed, the sheet is then conveyed to the sheet feeding unit 9 in the same manner as the operation of the first pass, and the sorting operation is started in the second pass, the third pass, and arranged in a predetermined order. In other words, the directions are assembled. After that, it shifts to delivery work.

The above is the general flow of processing in this sorting machine. FIG. 4 is a flow chart conceptually summarizing the overall flow of the processing. That is, in FIG.
When the paper arrives (arrival of the flight), the operation preparation for sorting operation is started. In this work preparation, for example, delivery zone 0
1, 02, 03,... Are usually sorted and processed for each delivery zone (unit). Then, the first sorting operation (one-pass work) of the delivery zone 01 is performed, and when the one-pass work is completed, the paper sheets that have completed this pass are moved to a position different from the sorting port. Post-pass work (post-pass work) is performed. Subsequently, a second sorting operation (two-pass work) is performed. When the two-pass work is completed, a post-pass work such as relocating the paper sheet having completed this pass to a position different from the sorting port. (Post-pass work) is performed. Subsequently, a third sorting operation (3-pass operation) is performed.

When the sorting operation of the third pass of the delivery zone 01 is started, the preparation for the sorting operation of the first pass of the delivery zone 02 in which the sorting operation is performed is started. The operator starts the first pass of the delivery zone 02 (may be the second pass or the third pass if the first pass of the delivery zone 02 has already been completed) by operating a key (not shown) of the input operation unit 12b. Instruct. Then, the system control unit 20 calculates the maximum total number of divisions required when the sorting operation of the third pass of the delivery zone 01 is completed and subsequently the sorting operation of the first pass of the delivery zone 02 is started. At the same time, it is determined whether or not the number of sorting ports 3a in the paper sheet sorting unit 3 has room. In this determination, when there is no margin in the number of divisions, the division operation using the first division table 21 is performed, and when there is a margin in the number of divisions, the division operation using the second division table 22 is performed.

Here, the contents of the first sorting table 21 are shown in FIG. 5A, and when the sorting process is performed using the first sorting table 21 in FIG. Part 3 shows an example of a state in which the paper sheets are actually sorted into the sorting openings. That is, in the first sorting table 21,
The sorting process of the third pass of the delivery zone 01 is completed, and then the sorting port used in the sorting process of the first pass of the delivery zone 02
The division port scheduled for the division port adjacent to the division port of the delivery zone 01 is set to be shared with the division port of the delivery zone 01. More specifically, in the table of FIG. 5A, the sheet delivered to the delivery location BC550 of the delivery district 01 is stored in the sorting port 02 where the paper is stored, and delivered to the delivery locations BC551 and BC552 of the delivery district 02. Paper sheets are stored. Therefore, when the sorting process is performed using the first sorting table 21, no gap is created between the delivery zone 01 and the delivery zone 02, and the sharing of the sorting port improves the efficiency of using the sorting port. be able to. When the mode using the first sorting table 21 is selected, the signal card 23 decorated with a color whose surface is conspicuous, for example, serves as a mark of the boundary prior to the insertion of the paper sheets in the delivery area 02. It is thrown. Then
The signal card 23 is automatically sorted and stored between a boundary portion, that is, the delivery point BC550 of the delivery zone 01 and the delivery location BC551 of the delivery zone 02 in this embodiment. FIG. 5B shows this state. In the case of this mode, while the sorting process of the first pass of the delivery zone 02 is being performed, the paper sheets after the sorting process up to the third pass are taken out from the sorting port, and if necessary, From the class sorting section 3, the sheet is transferred to the storage shelf 5 via the sheet transporting means 4, and then the delivery is started. In addition, in the division mouth shared with the delivery zone 02, the signal card 23
Is marked as a boundary mark, so that only the sheets in the delivery zone 01 can be scraped out from the sorting port and taken out using the signal card 23 as a mark in the sorting port where the signal card 23 is inserted. During this time, the sorting operation of the delivery zone 02 is in progress, and the delivery zone 0 is in progress.
When three passes are completed in the same manner as in 1, and the sorting operation is performed for the next delivery zone 03, the processing is performed in the same manner as in the case of the delivery zone 02.

On the other hand, the contents of the second section table 22 are shown in FIG.
6 (a), and FIG. 6 (b) shows a state in which the paper sheets are actually sorted into the sorting port in the paper sheet sorting unit 3 when the sorting processing is performed using the second sorting table 22. An example is shown. That is, in the second sorting table 22, the sorting process of the third pass of the delivery zone 01 is completed, and then the sorting ports of the delivery zone 01 among the sorting ports used in the sorting process of the first pass of the delivery zone 02. The division port scheduled for the division port adjacent to is set to a division port different from the division port of the delivery zone 01. More specifically, in the example of FIG. 6, the sorting port 02 in which the paper sheets to be delivered to the delivery location BC550 of the delivery area 01 are stored halfway, and even if there is still room for storage, The paper sheets sorted to the delivery location BC551 of the delivery zone 02 to be sorted are set so as to be sorted to the sorting port 03 prepared next. Therefore, in the case where the sorting process is performed using the second sorting table 22, a gap (empty) is created between the delivery zone 01 and the delivery zone 02, and the sorting is performed as compared with the case where the first sorting table 22 is used. Mouth efficiency is reduced. But,
In the case where the second sorting table 22 is used, since the delivery zone is divided for each sorting mouth, the work after the pass is simplified, and it is not necessary to insert a signal card into the sorting mouth. In the case of this mode, while the sorting process of the first pass of the delivery zone 02 is being performed, the paper sheets after the sorting process up to the third pass are taken out from the sorting port, and if necessary, It is transferred from the classifying section 3 to the storage shelf 5 via the sheet transporting means 4 and heads for delivery (delivery). During this time, the sorting operation of the delivery zone 02 is in progress, and the three passes are completed as in the case of the delivery zone 01. When the sorting operation of the next delivery zone 03 is performed, the processing is performed in the same manner as in the case of the delivery zone 02. I do.

More specifically, the system control unit 20
However, the determination as to which of the first partition table 21 and the second partition table 22 is to be selected is made, for example, as follows. First, in this example, a three-pass route assembly is performed by a sorting machine having 30 valid sorting ports, and the maximum total number of delivery points = 30 × 30 × 30 = 2700000 The number of first-passing points in the third pass = 30 × Assuming that 30 = 900, in the next case A, the sorting operation is performed using the first sorting table 21, and in the case B, the sorting operation is performed using the second sorting table 22.

(Case A): When the number of delivery sections = 16 and the number of points in each section = 910, the total number of delivery points = 910 × 16 = 14560, which can be realized by the sorting operation using the first sorting table 21, In the operation using the second sorting table 22, one mouth of each section is insufficient, and 30 mouths cannot be realized. Therefore, in this case A, the system control unit 2
0 uses the first sorting table 21 and employs a sorting operation using a method of continuously allocating delivery locations without gaps when the delivery zone changes.

(Case B): When the number of delivery sections = 14 and the number of points in each section = 910, the total number of delivery points = 910 × 14 = 12740, which can be realized by the sorting operation using the first sorting table 21. Even in the operation using the second partition table 22, one port in each section is insufficient, so two ports are allocated, and a total of (14 × 2 = 28) ports are required, but this is feasible. Therefore, in this case B, the system control unit 2
0 uses the second sorting table 22 with good workability, and adopts a sorting operation using a method of moving to the next sorting port even if the previous sorting port has room in the delivery section when the delivery area changes. .

In the above embodiment, the case where the pass is performed three times has been described. However, any number of passes may be used as long as the number is two or more. Also, a case has been described in which one processing unit (unit) is divided for each delivery zone, but other processing units (units) may be divided for each delivery time. Further, switching between the first sorting table 21 and the second sorting table 22 is performed by the system controller 2.
Although the description has been given of the case where the switching is performed with 0, the switching instruction may be given by the operator using, for example, a key or the like of the input operation unit 12B.

[0034]

As described above, according to the present invention,
A sheet sorting control device having the following excellent effects can be provided. -The first sorting table and the second sorting table are prepared in advance and can be selected. When the sorting process using the first sorting table is performed, the use efficiency of the paper sheet is reduced. When the sorting process is performed using the second sorting table, the use efficiency of the sorting mouth is reduced, but the work after the pass is not performed because the delivery area (unit) is divided by the sorting mouth unit. The effect of being simple can be expected. That is, when there is room in the number of divisions, the division operation is performed using the second division table, and when there is no room, the division operation is performed using the second division table. Sorting processing can be performed. In the case of using the first sorting table and arranging the sheets continuously in the delivery section, the signal card is arranged as a mark of the border at the border, so that the delivery section is used. The boundary between (unit) and (unit) can be immediately known, and workability can be improved. -If the signal card is inserted prior to the paper sheet, the signal card is automatically sorted and arranged at the boundary, so that the signal card can be easily arranged.
