Description

[Detailed description of the invention] This invention is a paper sheet counting machine that automatically counts bundles of paper sheets. This invention relates to an abnormality display reset circuit for a paper sheet counter, which aims to improve recovery operations after an abnormality is detected.

Conventional paper sheet counting machines, such as those used in banking, place a stack of paper sheets on a holder and then rotate the paper stack toward the rotating cylinder. It is brought into contact with the suction head, and then the suction head suctions and separates the sheets of the stack one by one and counts them. FIG. 1 shows a counting control circuit of such a paper waste counter, and in the figure, reference numeral 1 is a start switch. This start switch 1 drives the holder device drive control section 2 when a start button provided on the holder is pressed. As a result, the stack of paper sheets placed on the holder is rotated toward the rotary cylinder, and the first sheet of paper is brought into contact with the suction head provided on the rotary cylinder, thereby closing the suction hole. Then, the cover device drive control section 3 closes the protective cover to protect the abnormality detection means of the optical system from external light.

On the other hand, when the start button is pressed, the vacuum pump starts sucking air in the suction hole, and when the vacuum level in the suction hole reaches a predetermined level, the vacuum switch 4 is turned on (signal SI is "1"). ”). As a result, the rotary tube rotates under the condition that the protective cover is closed, and the suction head revolves while rotating, and the paper is separated by suction and counted one by one. The non-contact switch 5 generates a counting pulse S2 every time the rotary cylinder rotates and the suction head adsorbs and separates paper waste.
It functions as a pulse supply means that sends the synchronizing signal TP20 to the sheet number counting section 7 and the timing pulse generation control section 8 via the AND gate 6.

The number counting section 7 counts and displays the number of defective sheets in the bundle of banknotes placed on the holder, and the timing pulse generation control section 8 detects abnormalities during counting, such as mixing of different types of banknotes, poor detection, double feeding, etc. Detection signals TP1, TP21, and TP22 for detecting are sent to the bill type discrimination section 9, the normal bill signal storage section 10, and the abnormality detection section 11, respectively. That is, the dimensions of the paper waste that is being counted are measured by the upper end position detecting section 12 and the lower end position detecting section 13. These measurement results are sequentially sent to the bill type discrimination section 9 in synchronization with the synchronization signal TP1, where they are converted into a denomination signal.
The valid note signal storage unit 10 stores the denomination signal sent from the first defective paper according to the synchronization signal TP21 as a valid note signal, and this valid note signal is sent to the abnormality detection unit 11. be done. The abnormality detection unit 11 sequentially compares the normal bill signal and the denomination signals from the second and subsequent failed sheets using the synchronization signal TP22, and detects the mixing of different types of bills if the comparison results do not match. A detection failure is detected when the shadows of both ends of the paper are not imaged on the upper end position detecting section 12 and the lower end position detecting section 13. In addition, in double feeding, the center transmitted light detection unit 14 measures the amount of transmitted light from the paper defect in the middle of counting, and compares this transmitted light amount with a preset amount of transmitted light from one sheet of paper. 15 and detected by comparison.

If such an abnormality occurs during counting, the abnormality detecting section 11 drives the batch device driving section 16 to stop the counting of paper waste, and causes the abnormal state to be displayed on the abnormality display section 17. The comparison section 18 compares the count value of the sheet number counting section 7 and the preset value of the sheet number setting section 19. If these values match, the holder is transferred via the gate control section 20. A holder release signal is sent to the device drive control section 2. However, only when an abnormality occurs, the abnormality detection section 11 prevents the sending of the holder release signal. The holder is rotated to the mounting position in response to a holder release signal or operation of the clear switch 21. On the other hand, the protective cover opens when the vacuum switch 4 is turned off (signal S1 is "0").

Incidentally, the above-described abnormality detected and stored by the abnormality detection section 11 is reset by a clear signal supplied from the clear switch 21. As a result, the batch device driving section 16 releases the batch device, and the abnormality display on the abnormality display section 17 is also reset.

Conventionally, when an abnormality is detected and counting is interrupted by the operation of a batch device, the operator presses the clear switch 2.
1 was pressed, the stack of paper defects was taken out, and the paper defects determined to be abnormal were inspected and confirmed. However, in this case, since the number of sheets displayed on the sheet number display section 7 is also cleared, the operator must remember the abnormal state and the number of sheets displayed before pressing the clear switch 21, which is inconvenient. , there was a risk of erroneous confirmation.

In view of the above circumstances, this invention provides an abnormality display reset circuit for a paper sheet counter that resets the abnormality display when an abnormality occurs and the sheet count display at that time when the start button is operated. It is something.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of this invention, and in this figure, parts corresponding to those shown in FIG. 1 are given the same reference numerals.

In other words, the difference from the conventional example shown in FIG.
If an abnormality such as mixing of different types of bills, detection failure, or double feeding is detected and the paper count is interrupted, the holder device drive control section 2 and the batch device drive section 16 are reset by the clear switch 21; The point is that the signal generated by operating the start switch 1 is used as a clear signal and is supplied to the sheet number counting section 7 and the abnormality detection section 11 for resetting.

Analyzing this from an ergonomic perspective, first, counting is interrupted when an abnormality is detected. The type of abnormality is then confirmed using the abnormality display section 17. If the abnormality is, for example, the mixing of different types of notes, the holder and batching device are opened by pressing the clear switch 21, and the stack of paper with the different types of notes mixed is taken out. At this time, since the number of defective paper sheets until a different type of ticket is detected is displayed in the number counting section 7, the inspection of the defective paper stack can be omitted up to the displayed number of sheets, and the inspection can be carried out easily and quickly. After completing this inspection, place the paper bundle on the holder,
Press the start button again. The start switch 1 is operated in conjunction with the operation of this start button, and the signal output from the start switch 1 is supplied as a clear signal, thereby resetting the number counting section 7 and the abnormality detection section 11 and starting re-counting. be done. In this way, a series of actions are performed in an orderly manner through simple operations and thinking. However, according to the conventional method, it is necessary to memorize the number of different types of tickets until the time when the clear switch 21 is pressed. Then, the inspection of the paper stack and the storage of the displayed number of sheets are performed at the same time.
It can also cause misunderstandings.

Note that these sheet number counting section 7 and abnormality detection section 1
1 is reset by a single pulse sent out from when the start switch 1 is operated until the transition to counting operation, that is, by a counting start signal sent out at the time when the vacuum switch 4 is turned on. You can also do it.

Note that FIG. 3 is a waveform diagram showing the relationship among the output signal S1 of the vacuum switch 4, the output signal S2 of the non-contact switch 5, and the synchronization signals TP1, TP20, TP21, and TP22.

As explained above, according to this invention, since the abnormality detection part and the number counting part are reset by operating the start switch, the recovery operation after an abnormality is detected becomes smooth. This has the advantage of eliminating the fear of misidentification.
