Abstract

PURPOSE:To improve the operation efficiency of a machine by installing a sorting-signal generating circuit which sends-out a sorting porhibiting signal into a sorting circuit and sends-out a taking-out permission signal into a taking-out circuit, when a full-state is detected by a full-state detecting circuit. CONSTITUTION:The comparator 11 in a measurement part 24 compares the discrimination code 10 with the discrimination code 9 read according to paper 6, and when the both codes coincide, a coincidence signal 12 is outputted. When the paper 6 crosses an optical switch 7, count-up is performed in a counting circuit 5. Said counted value 15-1 is compared with an allowable counted number 17 in a comparator 18, and in case of A>B, a condition coincidence signal 16 as the proof of no-trouble in agglomeration is outputted, and when a full-state is detected in a full-state detecting circuit 4, a taking-out permission signal is outputted into a taking-out circuit 2 of an agglomeration box 1, and a sorting prohibiting signal is outputted into a sorting circuit 3 through OR and AND circuit 22 and 25. Therefore, even if paper is transported to the agglomeration box during the taking-out of the agglomeration box, the presence of the agglomerated paper to be discharged can be obviated.

Description

[Detailed description of the invention] (Technical field to which the invention pertains) The present invention relates to a paper sheet sorting control circuit.

(Prior Art) First, the term "full" used in the present invention is defined to mean "semi-full" which has room for a certain number of accumulations.

Conventional paper sheet sorting control circuits have configured a control circuit in which a full signal from a stacking box in which paper sheets are accumulated is used as an input signal to the sorting control circuit.

Therefore, when a full signal was output from the stacking box, a take-out control signal was immediately output, so even if there were paper sheets that should be stacked in the corresponding stacking box, they could not be stacked because the corresponding stacking box was being taken out, so they had no choice but to stack. They were removed and accumulated in unusable boxes.

This has the disadvantage that when the processing time in the machine becomes long, the number of filter paper sheets that are removed and accumulated reaches a non-negligible number, which deteriorates work efficiency.

(Object of the Invention) The object of the present invention is to solve the above-mentioned drawbacks by suppressing the generation of a take-out signal when paper sheets and the like scheduled to go to a full stacking box are on the conveyance path. Our goal is to provide the following.

(Structure of the Invention) In order to achieve the above object, a sheet sorting control circuit according to the present invention includes a take-out circuit, a sorting circuit, and a full detection circuit. In the paper sheet sorting control circuit that controls the stacking box according to the paper sheets being conveyed, a count is started when the identification code corresponding to the stacking box matches the identification code of the paper sheet being conveyed. , a counting section that counts down when a sorting signal is received from the sorting circuit, and when the value of the counting section is O and a full signal is sent from the full detection circuit, a sorting prohibition signal is taken out to the sorting circuit. It consists of a classification signal generation circuit that sends an extraction permission signal to the circuit.

According to the above configuration, paper sheets are transported to the collection box while the collection box is being taken out, and it is possible to eliminate all paper sheets that cannot be stacked and must be removed and stacked, thereby improving the operational efficiency of the machine. The objectives of the invention are fully achieved.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a circuit block diagram showing an embodiment of a sheet sorting control circuit according to the present invention.

This figure shows a division control circuit corresponding to one accumulation box. The integration box l has a takeout circuit 2, a division circuit 3, and a full detection circuit 4.
It is composed of The take-out circuit 2 is a circuit for taking out the accumulated paper sheets when a take-out permission signal is input.

The sorting circuit 3 is a circuit for taking in conveyed paper sheets. The full detection circuit 4 is a circuit that outputs a full signal when the sorted paper sheets become full.

The measurement unit 24 includes a comparator 11. It is composed of an AND circuit 13 and a counting circuit 5.

The comparator 11 is a circuit for comparing the portrait identification code 12 with the identification code 9 read from the paper sheet 6. Therefore, when the identification code 9 read from the conveyed paper sheet matches the corresponding identification code 12, that is, when the corresponding paper sheet exists in the conveyance path, the coincidence signal 12
Output.

When the paper work 6 crosses a photoelectric switch 7 consisting of a light emitting diode and a phototransistor, a cutoff signal 8 is outputted from the phototransistor.

The AND circuit 13 inputs the match signal 12 and the cutoff signal 8, and generates a signal 14 that causes the counting circuit 5 to count up only when both signals are output.

The counting circuit 5 is an up/down counter, and the one division signal 21 is inputted as a countdown signal.

Therefore, when it is detected and classified by the photoelectric switch 7, it is counted up and then counted down, so the counted value is 10#, and the output signal 15-
1 is the count value, and 'l' is output as the output signal 15-2. This is when there are no paper sheets to be stacked in the corresponding stacking box on the conveyance path. On the other hand, the photoelectric switch 7 However, when there is an unsorted paper sheet, the counted value is 1" or more, and the counted value is output to the output signal 15-1, and 0" is output to the output signal 15-2. be done.

The comparator 18 is a circuit for inhibiting the removal of paper sheets from the stacking box l even when the number of paper sheets present on the conveyance path exceeds a predetermined number.
1 and outputs a condition match signal 16 when conditions A) and B are satisfied. In addition, the output signal 15 of the counting circuit 5
It is a value of -1, and B is a preset allowable number of messages.

The comparator 18 is provided to avoid the large number of paper sheets on the conveyance path, which may cause trouble if all of them are accumulated.

The division signal generation circuit is an OR circuit 22. It is composed of an AND circuit 16 and an inverter.

When the output signal 15-2 of the counting circuit 5 is @1", or when the comparator 18 detects that the allowable number of passes has been exceeded, the OR circuit 22 outputs the condition match signal 16, and the AND circuit 25 outputs the condition match signal 16. The AND circuit 25 outputs a take-out permission signal 19 when the condition matching signal and the full signal match, and the take-out permission signal 19 is sent to an inverter to generate a sorting prohibition signal 2o.

In this example, the case where a photoelectric switch is used to detect paper sheets has been described above, but the method for detecting paper sheets is not limited to photoelectric switches. You can also do that.

In this figure, the classification control circuit for one stacking box is described, but it is possible to configure an apparatus in which dividing control circuits corresponding to the number of stacking boxes are combined.

(Effects of the Invention) As described in detail above, the present invention checks the paper sheets to be accumulated in the corresponding accumulation box when the accumulation box is full, and controls the take-out circuit. It is possible to minimize the amount of paper sheets that go to the machine and realize an efficient conveyance control circuit. In addition, the position and threshold of the photoelectric switch and other detectors can be arbitrarily specified depending on the size of the collection box, the take-out time, and the number of sheets that can be stacked from detection of fullness until stacking becomes impossible, making it easy to configure the device. It is expressed in
