DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an overall configuration diagram of a paper sheet processing apparatus to which the present invention is applied. That is, as shown in FIG. 1, the housing 1 is provided with an operation panel 2, and by operating a switch SW on the operation panel 2, the start and stop of the operation of the sheet processing apparatus is controlled. .

Further, in the housing 1, there is provided a paper feed table 3 into which paper sheets (not shown) to be processed are loaded and deposited, and the paper sheets deposited and deposited in the paper feed tray 3 are provided. A take-out device 4 including a roller for separating and taking out the pieces one by one is provided.

The paper sheets taken out by the take-out device 4 are sent out to the belt-shaped first conveying path 18 provided in the housing 1 and conveyed,
The passage is checked by the first paper sheet passage check sensor 5 and the information is read by the information reading means 6 and 8 and then sequentially conveyed to the first sorting machine 9.

The first sorting machine 9 is the information reading means 6
So that the first paper sheet whose information cannot be read accurately by means of 8 and 8 and the specially selected second paper sheet are conveyed to the second sorting machine 10 via the second conveying path 19. Sort into.

The second sorting machine 10 sorts the first paper sheets so that they are conveyed to the first stacking section 12 and the second paper sheets to the second stacking section 11. The first sorter 9 is a paper sheet other than the first and second paper sheets, that is, a paper sheet whose information is accurately read by the information reading means 6 and 8 or a paper sheet which cannot be specially selected. Many third paper sheets including paper are sorted so as to be transported to the third sorting machine 13 via the third transport path 20.

It is assumed that there are two types of paper sheets of different sizes (however, the amount of information is different) as the paper sheets processed in this embodiment. The larger one of these is fed to the third stacking unit 21 by the third sorting machine 13.
The sheets are distributed so as to be conveyed between them, and the smaller paper sheets are similarly distributed so as to be conveyed to the fourth stacking units 141 and 142.

In this experimental example, the fourth accumulation units 141, 14
The same two as 2 are prepared, and when one stacking unit 141 becomes full by the fifth sorting machine 15, it is distributed to the other stacking unit 142.

Further, the partition paper feeding device 16 is adapted to feed the partition paper to the stacking section 141 or 142 for each specific partition of small paper sheets. The control device 17 includes a CPU, etc., as shown in FIG.
It controls the entire sheet processing apparatus and includes the operation panel 2 and the first sheet passing check sensor 5 (including sensors provided at other places) and information reading means 6 and 8. It also has a role of transferring predetermined information to an external host device and the like while being connected to an external host device or the like.

FIG. 2 shows a concrete example of the paper feed table 3 and the take-out device 4. That is, as shown in FIG. 2, the upper end detection unit 3 a provided on the upper portion of the paper feed tray 3 detects the sheets stacked on the uppermost portion of the paper feed tray 3 and is provided on the lower portion of the paper feed tray 3. By controlling the vertical movement of the backup plate 3b, the uppermost paper sheet is always the roller 4a of the take-out device 4.
Thus, it is sent out in the direction of the transport path 18.

By the way, regarding the takeout of the paper sheets from the paper feed table 3 as described above, there are two kinds of paper sheets handled by the paper sheet processing apparatus, which are large and small. It is necessary to take out at two kinds of take-out speeds in relation to the processing time in the information reading means 6 and 8.

In this case, the take-out speed of the take-out device 4 is determined by the number of rotations by the motor 4b (see FIG. 3) that rotationally drives the roller 4a. Therefore, in the present invention, as shown in FIG. 3, the paper sheet conveyed by the control device 17 to the inverter 21 as the rotation speed changing means of the motor 4a in response to the check signal from the first paper sheet passage check sensor 5. The control system is configured to supply a rotation speed switching signal according to the size of the class.

In this case, the inverter 21 outputs a motor drive signal of a low frequency for low speed (for example, 30 Hz) to a large paper sheet (for example, 110 mm × 280 mm), and a small paper sheet (for example, 56 mm × 76 mm). Is configured to output a motor drive signal of high frequency for high speed (for example, 60 Hz).

Next, a specific example of changing the take-out speed will be described with reference to the flowchart shown in FIG. When the operation of the paper sheet processing device is started, the control device 17 supplies the inverter 21 with a command signal for driving the motor 4b at a high speed regardless of the size of the paper sheet on the paper feed tray 3. .

As a result, the motor drive signal having a predetermined frequency for high speed is output from the inverter 21 to the motor 4b, and as a result, the take-out device 4 picks up the first sheet from the paper feed table 3 with a high take-out speed. It is taken out and sent out on the conveying path 18 (step S1).

As soon as the first sheet of paper is sent out onto the conveying path 18, the first sheet of paper passage check sensor 5 detects it.
Checked in 1 through the control device 17
It is determined whether the first sheet is a large sheet or a small sheet (step S2).

When it is determined in step S2 that the first sheet is a large sheet, the control device 17 supplies a command to the inverter 21 for changing the rotation speed of the motor 4b to a low speed (step). S3).

As described above, when the sheet speed is changed to low, or when it is determined in step S2 that the first sheet is a small sheet, two sheets are fed from the paper feed tray 3 while the motor speed is kept high. The paper sheets after the eyes are taken out.

That is, the second and subsequent sheets are taken out at the normal take-out speed, and the information reading means 6 and 8 are taken.
Therefore, the paper is fed at an accurate take-out conveyance interval. In this type of paper sheet processing apparatus, it is rare that different kinds of paper sheets are mixed on the paper feed tray 3, and normally, for example, only large paper sheets are concentrated and processed in a certain period. However, when that is done, it will take the sole form of concentrating and processing small paper sheets in the next period.

However, in the apparatus according to the present invention as described above, the processing can be performed at an appropriate take-out speed according to the size of the paper sheet regardless of whether the apparatus is single or mixed.

Incidentally, as shown in FIGS.
The speed V _B and the final speed V _R1 when the paper sheets are peeled off the take-out device 4 are V _R1 ≈V _B at the time of high-speed take-out (when taking out small paper sheets).

When the take-out device 4 is set to the final speed V _R2 when the paper sheets are peeled at the time of low-speed take-out (when taking out large paper sheets), V _R2 <V _B.

That is, both speeds V _B and V _R1 during high-speed extraction
Since the paper paths are substantially equal to each other, the paper sheets can be smoothly drawn into the conveyance path 18, and the paper path does not bend because the conveyance path V _B is larger than V _R2 when the paper is taken out at a low speed. As described above, since the sheet is forcibly drawn into the conveying path 18, the conveying path 1 is surely obtained in any case.
8 will be sent out.

According to the paper sheet processing apparatus of the present invention as described above, the take-out speed of the paper sheet is set so that one apparatus can process the paper sheet at an appropriate processing speed according to various kinds of paper sheets. Can be changed easily and automatically.

[0035]

Therefore, according to the present invention as described in detail above, a paper sheet that can be easily and automatically changed to an appropriate processing speed according to various kinds of paper sheets and processed. It is possible to provide a similar processing device.
