JPH069134A - Carrying control device for paper sheet - Google Patents

Abstract

PURPOSE:To provide a general-purpose carrying control device for sheets of paper, which can reduce photoelectric switches in number over a carrying path and concurrently can be adapted to any kind of means only with a basic action pattern changed. CONSTITUTION:When paper sheets pass through a photoelectric switch 1 over a path 3, an action pattern write section 4 to which signals from a photoelectric switch amplifier 2 and the recognition codes of running papers are inputted, allows the action patterns of points 11a and 11b over the path in accordance with the recognition codes to be written in a memory section 5 on the basis of present time given by an interval timer 7. A read control section 8 reads the action information of the points 11a and 11b, which corresponds to the present time given by the interval timer, out of the memory section 5 so as to be stored in a register 9. Information stored in the register 9 is turned out to be open/close information for the respective points 11a and 11b by a point driver 10.

[0003]

The above-described conventional paper sheet conveyance control device requires a large number of photoelectric switches and photoelectric switch amplifiers in order to detect the position of the paper sheet on the conveyance path so as to absorb the speed fluctuation. Met. In addition, the position and identification code of each paper sheet are managed in real time, the branching condition at the branching point is constantly checked, and the rolling is controlled. Since it is necessary to change the design every time, there is a drawback that the device scale is large and complicated and lacks flexibility.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore an object of the present invention is to provide a novel paper sheet conveyance control capable of solving the above-mentioned drawbacks inherent in the prior art. To provide a device.

In order to achieve the above object, a paper sheet conveyance control device according to the present invention includes a photoelectric switch disposed on a conveyance path and a switch for a branch point on the conveyance path. A storage unit that stores an operation pattern, a writing unit that writes the operation pattern of the switch at each branch point to the storage unit based on the signal of the photoelectric switch, and a pulse that generates a pulse that follows the transport speed. A generator, an interval timer that operates by a signal from this pulse generator, a read control unit that reads the contents of the storage unit, a register that stores the operation information of the switch and a switch driver.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings with reference to the accompanying drawings.

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

Referring to FIG. 1, when a paper sheet passes through the photoelectric switch 1 on the conveying path 3, an operation pattern in which a signal from the photoelectric switch amplifier 2 and an identification code of the paper sheet in transit are input. The writing unit 4 writes the operation patterns of the switching devices 11a to 11e on the conveying path according to the identification code in the storage unit 5 based on the current time from the interval timer 7.

The interval timer 7 operates by a signal from the pulse generator 6 which outputs a pulse according to the transport speed, and outputs a read signal at a fixed time.

The read control unit 8 includes an interval timer 7
The operation information of the switching devices 11a to 11e corresponding to the present time is read from the storage unit 5 and stored in the register 9. At this time, the operation information corresponding to the same time is deleted from the storage unit 5.

The information stored in the register 9 becomes the opening / closing information of each of the point switches 11a to 11e by the point switch driver 10.

Next, the storage unit 5 will be described with reference to FIGS.
Will be described in detail.

When a sheet reaching the stacking unit A arrives at the photoelectric switch 1 at time t0 in FIG. 1, the operation pattern writing unit 4 writes the contents as shown in FIG. . In FIG. 2A, the tumbler 11a moves from time t5 to t.
Operates for 7. This is because the time is determined by the speed of the transport path 3 and the distance from the photoelectric switch 1 to each of the tumblers. In particular, since the conveyance speed is fed back to the interval timer 7 by the pulse generator 6, the operation of the tumbler is executed at an appropriate timing even if the speed changes. In the present embodiment, the time shown in FIG. 2 is set by considering that the time from the photoelectric switch 1 in FIG. 1 to the switch 11a is 5 and the time to the switch 11e is 13.

Next, when the time elapses and the sheets for the stacking unit B reach the photoelectric switch 1 at time t6, the contents of the storage unit 5 are updated as shown in FIG. 2 (b). In this case, the time from the photoelectric switch 1 to the rolling device 11b is set to 7. Therefore, in FIG. 2B, the rolling device 11b is set at the time t1.
It operates from 3 to t15. FIG. 2B shows that only the rolling device 11a is operating at the current time t6.

Since the time of the interval timer 7 is configured as an endless counter and used as address information of the storage unit 5, the storage unit 5 functions as an endless buffer. The capacity of the storage unit 5 is determined by the resolution of the interval timer 7, the number of switch devices, and the time from the photoelectric switch 1 to the switch device having the longest distance.

[0016]

As described above, according to the present invention,
By storing the operation patterns of the turning device at each branch point on the transport path in advance in the storage unit according to the identification code, after the photoelectric switch that serves as the reference, transport is performed without detecting the movement of the paper sheet and checking the branch. You can control. At this time, the operation pattern of the switching device corresponding to each identification code can be determined by the reference photoelectric switch, the distance between each switching device, and the conveyance speed, and only by changing the reference pattern given to the operation pattern writing section. It can be easily applied to all types of equipment. Furthermore, by adopting a pulse generator that outputs a signal that follows the transport speed as the reference clock of the interval timer, it is possible to absorb dynamic fluctuations of the transport path and fluctuations due to aging, so stable rolling control is possible. Is.

Therefore, according to the present invention, it is possible to drastically reduce the number of photoelectric switches on the transport path and to provide a versatile transport control device that can be applied to any device by simply changing the reference operation pattern. can get.
