Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double adsorption detection device in a banknote counting machine.

In other words, in a banknote counting machine in which a suction shaft sucks and counts banknotes one by one from a group of banknotes loaded in a holder, a light beam is transmitted through the banknotes to be sucked and counted by the suction shaft, and double If it is suction, it is checked by the amount of transmitted light so that it can be detected and notified or the counting can be stopped.In particular, the suction shaft can accurately project light onto the banknotes that are being turned over, and if the banknotes that have been turned up are not being rubbed by the banknotes, etc. This is to ensure that Zuko's seed counting machine can be used in a reliable manner.

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

Figure 1 shows a plan view of the main parts of a banknote counting machine,
is a rotating cylinder, 2 is a suction shaft, 2a is a suction surface with a suction port, 3
is a holder, 4 is a banknote bundle, 5 is a presser bar, and 6 is a tension spring.

1, 7 is a motor, 8 is a belt, 9 is a detection switch, 10 is a vacuum switch, 11 is a gate circuit, 12 is a counter, and 13 is a display section, each of which has the same structure as the conventional structure.

In the block diagram shown in FIG. 5, 14 is an amplifier circuit;
5 is a comparison circuit, 16 is a gate circuit, 17 is a drive circuit, 1
8 is a lamp, 19 is an alarm circuit, and 20 is a monostable circuit.

A indicates a reflector such as a prism or a reflector, and the reflector A is fixed above the upper surface of each suction shaft 2. The reflectors A are each mounted on the suction shaft 2 so that the direction in which the light beam A projected onto the body A is reflected by the reflector A in a 90 degree direction and exits is perpendicular to the suction surface 2a of the suction shaft 2.

B is a light emitter that serves as a light source, C is a light receiver that serves as a light receiving element,
As shown by the arrow, the suction shaft 2 rotated by the rotary cylinder 1 contacts one banknote 4a on one side of the banknote bundle 4, and the suction surface 2a attracts and peels it off, as shown in FIGS. As shown in FIG. 4, the light receiver C is fixed at that position so that it can receive the light ray A emitted from the reflector A when it is turned over approximately 90 degrees, and the light ray A is projected in that way. The light emitter B is fixedly installed at a position perpendicular to the light receiver C so that it can emit light.

As shown in each figure, when the banknote bundle 4 set in the holder 3 is at the counting position, the vacuum switch 10 is turned on and the rotary tube 1 rotates in the direction of the arrow, and each suction shaft 2 is rotated. When it rotates in the convex direction of the arrow, the suction shaft 2 comes into contact with the outer surface of the tip of the banknote bundle 4, and the suction surface 2a attracts one banknote 4a and turns it over while being supported by the presser bar 5 and pushes it apart until it bends and turns it one after another. The sample is displayed on the display section 13 and counted.

By the way, if the bill 4a to be sucked is normal and there is only one bill,
As shown in FIGS. 3 and 4, the portion of the banknote 4a that is attracted by the suction surface 2a is about 90 degrees with respect to the longitudinal direction of the banknote bundle 4.
At the point in time when the bill is bent into a state close to 90 degrees, the light beam A from the projector B is reflected by the reflector A in the 90 degree direction, passes through the banknote 4a as it is, and is received by the receiver C, but the output associated with the reception of the light is is amplified by the amplifier circuit 14 and input to the comparator circuit 15 for comparison, and if the circuit is configured so that if they match, no output signal is generated, then the signal is not input to the gate circuit 16, and on the other hand, the gate circuit 1171 ), the monostable circuit 20 is operated by the output signals from the gate circuit 16, and an output is issued to the gate circuit 16 for a certain period of time. However, since no output is issued from the comparator circuit 15, no output is issued from the gate circuit 16, and the drive circuit 17 is not activated, the lamp 18 is not lit, and the alarm circuit 19 does not issue an alarm, that is, the normal state is maintained.

Well, as mentioned above, the banknote 4a that is @ and N is abnormal and 2
When the number of banknotes reaches two banknotes, the amount of transmitted light is attenuated as the light ray A reflected by the reflector A passes through the two banknotes 4a. When this attenuation output is input to the comparator circuit 15, the circuit 15 outputs a mismatch signal. On the other hand, the output signal from the gate circuit 11 is input to the gate circuit 16 for a certain period of time in the same manner as described above, so the gate opens and the lamp 18 is turned on. It lights up and the alarm circuit 19 also operates to issue an alarm to notify the occurrence of an abnormality.

Note that it is also possible to configure the circuit to be configured to stop counting when such an abnormal situation occurs.

As described above, the present invention provides a banknote counting machine in which a suction shaft sucks and counts banknotes one by one from a group of banknotes loaded into a holder, and a reflector such as a prism or a reflector is provided on the top of each suction shaft. are attached respectively, and the transmitted light from the banknotes attracted to the suction shaft is projected in the refracting direction through the reflector, and the amount of transmitted light passing through the banknotes is adjusted to 2.
Since we have made it possible to check whether or not the suction shaft has double suction, it can be checked by analyzing the amount of transmitted light to notify you or stop counting, so that you will not be able to count one piece by mistake. In particular,
The suction shaft allows the light to be accurately projected and transmitted through the banknotes being turned over, and the light can be projected accurately without being interfered with by the banknotes being turned over, making it possible to reliably perform well with this type of counter. It has the characteristics of being able to
