Abstract

(57) [Summary] [PROBLEMS] To efficiently continue a sorting operation even when a sheet conveyance gap is narrow and a gate cannot be switched between the gaps. A feeder (102) for continuously feeding out paper sheets.
It is composed of a reader 105 for reading the sorting information described on the sheet, a plurality of sorting ports 1 to 7, a transport path, and a gate for guiding mail to the sorting port. A reject port RJ is provided at the last end of the transport path. Put the paper that could not be put in the mouth into the reject mouth. When the reject opening RJ is full, the sorting operation is not stopped, and the gate of this sorting opening is fixed so that the sheet destined for the reject opening can be inserted into the preceding sorting opening.

2. Description of the Related Art When separating paper sheets, if the transport gap of the paper sheets is narrow and the gate cannot be switched between the gaps, the two sheets can be transported without switching the gate. Transported to

[0003]

According to the above-mentioned technology, when the reject opening is full, there is no other way to stop the transport path because there is no opening for accommodating a paper sheet with a narrow gap even if the reject opening is further extended. . Even if an attempt is made to use the immediately preceding sorting port as the rejecting port, if the gate is operated for each sheet, there is a disadvantage that the sheet having a narrow gap is jammed here.

[0004] It is an object of the present invention to provide means for solving the above disadvantages.

SUMMARY OF THE INVENTION The present invention relates to a sheet sorting machine for reading information written on a sheet and continuously sorting the sheets, wherein at least a feeder or a sheet for continuously feeding the sheets is provided. It consists of a reader that reads the described sorting information, a plurality of sorting ports for inserting paper sheets, a transport path connecting them, a gate that branches mail from the transport path and leads it to the sorting port, and a reject port at the end of the transport path. When a reject port is full of paper sheets, the previous sorting port on the transport path is set to Handle it as a reject opening, open and fix the gate that guides the paper to this section opening, and insert the paper of the reject opening,
When the paper is removed from the reject mouth and full is released,
The gate is controlled again.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a sheet sorting machine according to the present invention. Reference numeral 101 denotes an operation panel having operation buttons for starting and stopping the sorting of paper sheets and other operations. Reference numeral 102 denotes a sheet feeding unit (feeder), which is used to set a sheet after setting a sheet.
01 By pressing the start button on the operation panel, paper sheets are continuously fed out one by one. Reference numeral 103 denotes a sensor for detecting the size of a paper sheet. For example, a sensor that detects a paper sheet that is too large or too small to enter the sorting port is transported to the storage unit 104. 105 is the classification information described on the paper sheet,
For example, it is a reader for reading a barcode or a character and deciding which storage port to store. RJ is a reject port provided at the rear end of the transport path and stores paper sheets that could not be stored in any of the sorting ports.

FIG. 2 shows the details of this reject port and the one before it, here the seventh port.
Reference numeral 06 denotes a paper sheet transport belt, and the paper sheet 12 has been transported sandwiched between the belts. Reference numeral 107 denotes a guide for guiding the paper sheet to the reject opening RJ, and the paper sheets (12, 13) that have reached this point are all stored in the reject opening RJ. Reference numeral 108 denotes a gate for storing the paper sheet (10) in the sorting port 7. An optical sensor 109 controls the gate 108, and the control method will be described later. 110
Denotes a sensor for detecting the fullness of the reject opening.

FIG. 3 shows a gate 108 using a sensor 109.
6 is a timing chart for controlling the operation of the first embodiment. According to this figure, when the paper sheet 10 passes between the optical sensors 109, the sensor 1
The light 09 is blocked by the paper sheet 10 and becomes dark. At this time, if the paper sheet 10 is to be stored in the sorting port 7, the gate 108 is opened. Thereby, the paper sheet 10 is stored in the sorting port 7. Next, assuming that the paper sheet 11 is to be stored in the reject opening RJ due to some factor, for example, the sorting information could not be read, the gate 108 remains closed even if the sensor 109 is shielded from light, and the paper sheet 11 is closed. The leaf 11 is guided by the guide 107 and stored in the reject opening RJ. Also, the paper sheet 12 is similarly placed in the sorting port 7.
Is stored in.

FIG. 4 shows a state where the gap gp between the sheets is narrow. In this figure, assuming that the paper sheet 10 is put into the sorting port 7 and the paper sheet 11 is put into the reject port, the paper sheet 10 is securely stored in the sorting port 7, but since the paper sheet 11 has a narrow gap gp, Even if the gate 108 is closed and it is attempted to send it to the reject port, the switching is not in time due to the electromagnetic operation delay, and there is a possibility that the gate may be erroneously entered into the division port 7 or jammed by the gate 108. Therefore, in order to solve this, the control is not generally performed as shown in FIG. 4, but as shown in FIG.
When p is narrow, the gate 108 is not moved, and
Both sheets are inserted in the reject opening RJ. By doing so, it is possible to prevent a situation where the user enters the sorting port 7 by mistake or is caught by the gate 108 to cause a jam.

However, when the reject opening RJ is full by the stack mail 13 and the full detecting sensor 110 is working, it is not possible to insert any more paper into the reject opening RJ. That is, in the case as shown in FIG. 5, the paper path is stopped because the paper sheets 10 and 11 cannot be inserted, and the paper sheet is withdrawn from the reject opening RJ, and the full detection sensor 110 waits for recovery. Restart the transport path when it is removed, and reject the mail 10 and 11
It will be stored in. However, in this method, since the transport path is stopped, the sorting operation is stopped during that time, resulting in poor efficiency. As a means for solving this, there is a method of setting the sorting port 7 to a reject port. However, in this method, the control of the gate 108 is performed for each sheet, and the problem of FIG. 4 in which a jam may occur cannot be solved.

FIG. 6 shows a method of controlling the gate 108 according to the present invention. When a narrow gap between sheets is also stored in the sorting port 7, the control of the gate 108 is stopped for each sheet, and the gate 108 is opened and fixed. Can solve it. As a specific method, while the reject opening RJ is being full by the full detection sensor 110, the gate 1 starts when the sheet reaches the sensor 109.
08 may be fixed open. In this way, the gate 108 does not perform gate control for each sheet, but functions as a guide for the paper sheet, and the sorting port 7 can be substituted for the reject port, so that the control problem of FIG. 4 can be solved. Paper sheet 1
3 is withdrawn from the reject opening RJ and full detection 110
Is released before the paper sheet 12 in the example of FIG. 6, when the paper sheet 12 passes through the sensor 19, the gate 10 is released.
Close 8 After that, it is good to return to normal control.
If the sorting is performed in this manner, the paper sheet that should be put in the reject port enters the sorting port 7, and it is necessary to re-sort. For example, the sorting port 7 is also defined as a reject port, and the reject port is 2 It should be treated as if there is one.

[0012]

According to the present invention, even if the reject opening is full, there is no need to stop the transport path, so that the sorting operation can be efficiently continued.
