CONSTITUTION:When the first paper sheet 10 intercepts light of a sensor 1 between its light emitting and receiving parts, a conveying path sorter plate driving part 6 is driven by a detection signal from a point end detecting part 4. Next, this driving part 6 receives from a drive direction detecting part 7 a drive direction command data, stored in a drive direction data storage part 8, of a conveying path sorter plate 3 for the first paper sheet 10, driving the conveying path sorter plate 3 in a predetermined direction. This first paper sheet 10, when its rear end passes through a position of the sensor 1, is detected by a rear end detecting part 5 outputting its detecting signal to the drive direction detecting part 7 being started. Next, this detecting part 7 adds 1 to an accumulated number of the possessing paper sheets 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a conveying device for paper sheets, and particularly to a sorting device for a conveyance path.

[Prior Art] Conventionally, this type of conveyance path sorting device detects the leading edge of a sheet, recognizes that a sheet has passed, and operates a conveyance path distribution plate to sort the sheets into a predetermined position. They were trying to sort it out to the transport route.

[Issue to be solved] Is it the conventional paper sheet conveyance path distribution mentioned above? Since the operation of the transport path distribution plate is determined by detecting the leading edge of the paper sheet, the drive circuit of the transport path distribution plate may pick up electrical noise or detect small pieces of paper sheets. There is a problem in that the passage of a paper sheet may be mistakenly recognized as the leading edge of a paper sheet, and the same operation as when one paper sheet passes may be performed, causing the conveyance path distribution plate to malfunction.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a conveyance path sorting device for paper sheets that does not malfunction due to electrical noise, passage of small pieces, etc.

[Means for Solving the Problems] In order to achieve the above object, a conveyance path sorting device for paper sheets according to the present invention has a conveyance path distribution plate, and distributes and conveys paper sheets to a plurality of destinations. In the conveying device, the paper!
a sensor for detecting the presence or absence of passage of paper sheets; a conveyance path distribution plate that is driven by a conveyance path distribution plate drive unit to rotate in forward and reverse directions and distributes the paper sheets to respective predetermined conveyance destinations; a leading edge detection unit that detects the passing timing of the leading edge of the paper sheet when the paper sheet passes through the sensor position; a trailing edge detection unit that detects the passage timing of the trailing edge; a drive direction data storage unit that stores directions in which the conveyance path distribution plate should be driven in the order in which paper sheets pass through the sensor position; A drive that determines the drive direction data to be extracted from the drive direction data storage section by detecting the rear end of the paper sheet by the rear end detection section, and drives the conveyance path distribution plate drive section in the forward and reverse directions based on the drive direction data. This configuration includes a direction detection section.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the figure, 1 is a sensor, and this sensor 1 detects whether or not paper sheets are passing. Specifically, it consists of appropriate light emitting and receiving parts,
When the paper sheet 1O blocks light between the light emitting and receiving parts, the output becomes 1", and when the paper sheet 1O does not block light, the output becomes "0" (see FIG. 2).

The conveyance path distribution plate 2 is driven by the conveyance path distribution plate drive unit 6 to rotate forward and backward in the direction of the arrow in the figure, and distributes the conveyance destinations of the paper sheets 1O to be conveyed. The conveyance path 3 is divided into two conveyance routes 3a and 3b on the conveyance tip side, and one paper sheet 10 is allocated to one of these two conveyance routes 3a and 3b by the conveyance path distribution plate 2. It looks like this.

In the figure, 4 is the tip detection section, and this tip detection section 4 is the sensor 1.
The passing timing of the leading edge of the paper sheet 10 when the paper sheet 10 passes through the position is detected.

Further, in the figure, reference numeral 5 denotes a trailing edge detection section, and this trailing edge detection section 5 detects the passing timing of the trailing edge of the paper sheet 10 when the paper sheet 10 at the position of the sensor 1 passes.

The conveyance path distribution plate drive unit 6 drives the conveyance path distribution plate 3 in the forward and reverse directions designated based on the command from the drive direction detection unit 7 . The drive direction detection unit 7 detects paper sheets 10 that have passed through the sensor 1.
It has a total number of sheets, and detects the forward/reverse driving direction of the conveyance path distribution plate 3 corresponding to this total number of sheets. As shown in FIG. 1, the drive direction data storage section 8 stores the direction in which the conveyance path distribution plate 3 should be driven for each number of sheets 10 that pass through the sensor l.

In the figure, each block (1) to (n) of the drive data storage section 8
``r positive 1'' or ``r reverse'' shown in

FIG. 2 is a graph showing a method for detecting the trailing edge of the paper sheet 10 in the trailing edge detection section 5 described above.

The output waveforms 9a and 9b are the output waveforms of the trailing edge detection unit 5 when the paper sheet 1o passes the position of the sensor 1. The timing for detecting the rear end is when the output of the sensor l changes to "0" after maintaining the state of "1" for a certain period of time. In the example shown in the figure, this certain period of time is set to time T. .Therefore,
At detection timing 11 of the output waveform 9a, it is detected that the rear end of the paper sheet 10 has passed the position of the sensor l, but at detection timing 12 of the output waveform 9b, the rear end of the paper sheet lO has passed the position of the sensor l. It will not be detected that it has been done.

Next, the operation of this embodiment will be explained.

When the −th paper sheet lO blocks light between the light emitting and receiving parts of the sensor l, the conveyance path distribution plate drive unit 6 is driven by the detection signal from the leading end detection unit 4, and the conveyance path distribution plate drive unit 6 is Receives drive direction instruction data for the transport path distribution plate 2 for the first sheet 10 stored in the drive direction data storage unit 8 from the drive direction detection unit 7, and controls the transport path distribution plate 2 to a predetermined position. Move W in the direction of .

When the trailing edge of the first paper sheet 10 passes the position of the sensor l, the trailing edge detector 5 detects this, outputs a detection signal to the drive direction detector, and activates the drive direction detector l. . The driving direction detection unit 7 detects the cumulative number of paper sheets 10 held by r.
