Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a counting control method in a banknote tilt counting machine, that is, a banknote tilt counting machine configured to count a group of banknotes loaded in a holder while being suctioned one by one by a suction shaft. Conventionally, when the suction shaft finishes sucking up the last banknote, atmospheric pressure enters the suction port of the next rotating suction shaft, and as a result, the vacuum switch is activated to control the input signal to the counter circuit. Therefore, depending on the operating time of the vacuum switch, it is often possible to start counting after the counting is completed, so it has been impossible to speed up counting beyond a certain limit.

The present invention has been made to eliminate the above-mentioned drawbacks, and is aimed at preventing erroneous counting due to increased speed.

Next, the embodiment shown in the drawings will be described.

Reference numeral 1 denotes a holder for a bundle of banknotes 3, which is connected via an interlocking rod 5 to a rotating body 4 driven by a holder motor (not shown), and opens and closes along a guide 2.

It is constructed by being pulled from the other side by a tension spring 6, and a holding rod 7 is erected on the other side.

Further, a suction shaft 10 having a suction port 9 is provided around the rotary cylinder 8 so as to rotate with the rotation of the rotary cylinder. Due to the planetary movement and suction action of this suction shaft 10, banknotes are drawn as shown in the second figure. Needless to say, a vacuum pump is acting on this suction shaft 10, and iron pieces 11 are arranged at regular intervals around the rotating cylinder 8, and on the sides of the rotating cylinder 8, iron pieces 11 are arranged at regular intervals. A non-contact switch 12 is provided, and a rotary cylinder 8 is rotated by a motor 13.The above structure is the same as that of the conventional structure.

The present invention uses an optical projector 14 as a detector.
A light receiver 15 is installed in this counting device, but a light emitter 14 is installed.
is fixed to the upper side of the rotary barrel 8, and the light receiver 15 is fixed to the upper side of the guide 2. As long as there is a remaining banknote group 3 that is turned over by the suction shaft 10 during counting, the light from the projector 14 will be applied to the banknotes. When the light is blocked, the light is turned over and bent to one side, the light is projected from the light projector 14 to the light receiver 15.

3 shows a block diagram, 20 is a vacuum switch, 23 is an input gate circuit, 24 is a counter, 2
5 is a display circuit, and 26 is a detection amplification circuit, and the detection amplification circuit 26 is configured to be activated when the light receiver 15 receives light.

When counting, the banknote group 3 is loaded with the holder 1 open to the position shown by A, and when the banknote group 3 is pushed by the interlocking rod 5 by the switch operation and set as shown in Fig. 1, the banknote group 3 is loaded. 3 is held by a holding rod 7.

At this time, the light from the light projector 14 is blocked by the banknote group 3 and does not reach the light receiver 15.

When counting is started and the rotary tube 8 rotates in the direction of the arrow port and each suction shaft 10 rotates in the direction of the arrow, the suction shaft 10 in contact with the banknotes rotates and receives 1. The sheets are peeled off one by one by suction, and as shown in FIG. 2, they are bent to one side from the support of the holding rod 7, and the non-contact switch 12 is activated to perform counting.

That is, when the vacuum switch 20 operates, the motor 13 rotates, and a signal from the non-contact switch 12 is input to the input gate circuit 23.
A signal from the vacuum switch 20 is also input to 3, and when the gate is opened and counted by the counter 24,
The result is displayed on the display circuit 25.

When the last sheet is reached, the suction shaft 10 turns over the last sheet while rotating in the direction of the arrow and rotating in the direction of the arrow C. When the suction shaft 10 turns over the last sheet, the light emitted from the emitter 14 is transmitted to the receiver. 15, the photoreceiver 15 immediately activates the detection amplification circuit 26 and immediately closes the input gate circuit 23.

Therefore, as soon as the last sheet is counted, the light receiver 15 receives the light and the input can be controlled immediately.

Regarding the necessity of detection according to the present invention, in actual operation mode, the relationship is as shown in the fourth diagram.

That is, in the fourth diagram, the AB line is the detector line, and the CD line is the detector line.
The line indicates the set suction pressure, and W indicates the operating line for bill suction counting.

When the suction pressure reaches the reference value of the CD line due to the operation of the vacuum pump, the suction operation begins, and each time this suction is turned over, it is counted, and this operation becomes the waveform of the W line. A count is made for each pitch of this waveform curve.While there are banknotes to be counted in the holder, this waveform curve is repeatedly drawn on line AB, but as soon as there are no banknotes left. Waveform W from line AB
This is because the object to be sucked disappears and the atmosphere flows in from the suction port, so the suction pressure also decreases greatly and the waveform W decreases.The present invention is designed to eliminate this suction of banknotes. This is sometimes very effective, that is, even if there are no more banknotes to count, immediately after that, the runt is corrected due to the existing operating inertia, and the W waveform also falls, and the CD line continues to draw the waveform. The problem is the positive count immediately after the banknotes run out, which results in a miscount that is slightly more than the actual number of bills. Although there is no need to count, since the operation is actually carried out at a considerable speed in all cases, the number of pitches between PQ in Figure 4 will inevitably result in a value that is counted more than the actual number. In reality, various inconveniences occur when the banknotes are counted, but according to the present invention, as soon as it is detected that the banknotes to be counted are missing, the counting is immediately stopped and the suction pump is also stopped, thereby eliminating the above-mentioned inconveniences. This invention has been highly evaluated in terms of its practical use, since the purpose of this type of equipment is money processing, which does not allow even the slightest error or miscount. It can be said that it is deservedly given.

As described above in detail, the bill counter of the present invention is configured such that a suction shaft that moves planetarily moves the bills of a bundle of bills held in a holder and flips them up one by one while attracting them, and counts the results of the flipping. A detector is set in the machine to detect when the last bill among the bills being counted is turned over, and the input signal to the counting circuit is controlled by the detection signal emitted by the detector. As soon as the last sheet is turned over, the input can be controlled by emitting light from the emitter to the receiver, achieving faster counting and preventing erroneous counts compared to the conventional device mentioned above. It also has the characteristics of greatly shortening the counting and piercing time and achieving it with a simple structure.In this example, an optical detection method was described as a detector, but it is also possible to detect the presence or absence of banknotes and output an output signal. It goes without saying that other suitable sources, such as ultrasonic waves, may be used as long as they emit light.
