In this case, when the coins conveyed by the common conveyance mechanism are sorted to the outlet corresponding to the denomination, there is a button that causes a gap in the switching operation.

In consideration of the above points, the present invention is designed to reliably detect conveyance errors such as abnormalities in the switching operation of the conveyance path, thereby further improving the reliability of the coin dispensing machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings, assuming that it is applied to a money dispensing machine having a money conveyance mechanism of the above-mentioned conveyance type.

There is.

Further, a delivery side guide roller sb is placed in rolling contact with the delivery side roller Rb of the belt v, and the roller sb and the belt V
In relation to this, a guide plate A is provided at a clockwise or counterclockwise rotation position as shown by arrow 5, and is rotated by a separate drive means (not shown), and the guide plate A rotates in the clockwise direction. position, the conveyed coins C conveyed by the belt v are sent out by the belt v and the roller sb to the coin holding box E1 arranged at the first outlet position, whereas the guide plate A is rotated counterclockwise. When it is in the rotating position in the direction, its lower end protrudes below the belt ■, so that the coin C is held and guided by the guide plate A and the roller sb, and the coin holding box is placed at the second outlet position. It is designed to be sent to E2.

Although not shown in FIG. 1, it is assumed that the belt V is cut out at the center in the width direction so that the lower end of the guide plate A can protrude downward.

In this embodiment, a first detection means consisting of a currency passage detector Dl is provided at a currency feeding side position of the currency transport path of the transport mechanism 1, for example, at an open position of the roller Ra and the suction head H. 1 is provided at the coin sending side position, for example, the position between the roller Rb and the box E11, and the position between the roller Sb and the box E2.
2 is provided in the second detection means consisting of the money passage detectors D2 and D3, respectively, at two positions.

Here, the detector D1. As D2 and D3, an optical detector consisting of a light projecting element a and a light receiving element can be used.

As shown in FIG. 2, the money conveyance error detection device of this embodiment is designed to obtain a verification signal of a scheduled pulse width after a scheduled time elapses from the time when the output signal of the first detection means Kl is obtained. It has a verification signal generation circuit 10 and a verification circuit 11 that verifies whether or not the second detection output is generated in the second detection means within a time interval corresponding to the pulse width of the verification signal.

The verification signal generation circuit 10 has a delay circuit T with a delay time r1, and provides the detection means with an output pulse d1 (d1 in FIG. 3) of 1 to the pulse generation circuit P via the delay circuit T. As shown in FIG. 3P, an output pulse P having a pulse width γ2 is obtained when a time γ1 has elapsed from the falling point of the output pulse d1, and this output pulse P is outputted via the output NAND gates G1 and G2. It is done like this.

Here, the delay time r of the delay circuit T is such that during the normal transport operation of the transport mechanism 1, the currency C passes through the sending-side passage detector D1 position and then passes through the sending-side passage detector D2 or D3 position. The value is preselected to be slightly smaller than the time required to carry out the transport (hereinafter referred to as normal transport time).

In addition, the pulse width γ2 is such that after the coin C reaches the sending-side passage detector D2 or D3, the pulse width γ2 is
If necessary, the value is preselected to be slightly larger than the time γ3 (d3 in FIG. 3) required to pass through the position.

In the case of this embodiment, the normal transport time to the detector D2 position and the normal transport time to the detector D3 position are made almost equal to each other, and accordingly, the normal transport time for these two transport paths is It is designed to form verification conditions.

That is, the generation circuit 10 has three R-S flip-flop circuits F 1 + circuits 2 and F3 and first and second differentiating circuits DF1 and DF2, and the differentiating circuit DPI detects the rising edge of the output pulse d1. The differential pulse df, (third
df1) and convert it into the Q of the flip-flop circuit F2.
The output is received as an open signal and applied to the set input terminal S of the flip-flop circuit F1 via an ant game (Ant-G) G3, while a differential pulse df2 (Fig. 3 df2) is obtained at the falling edge of the output pulse dl in the differentiating circuit DF2. This is then applied to the set input terminal S of the flip-flop circuit F2.

fmll. ■2 and ■3 are inverters.

On the other hand, the flip-flop circuit F3 transfers the transported coins to the outlet E1.
or B2, and its set input terminal S is provided in connection with, for example, a drive means (not shown) for guide plate A (FIG. 1). The switching output O8 of the switching signal generation circuit O8 is connected to the circuit F2.
The Q output of the gate is given as an open signal via an ant game (G4).

In this embodiment, when the guide plate A is in the counterclockwise rotation position and the conveyed currency C is conveyed to the holding box E2, the generating circuit O8 is activated at a scheduled timing after the pulse d1 is obtained.
It is assumed that the switching output OS of the HJ level is generated (FIG. 3 OS), and in other cases, the switching output OS of the "L" level is generated.

The Q and Q outputs of the flip-flop circuit F3 are given to the output gates G1 and G2 as horizontal opening condition signals, thus obtaining the horizontal opening output TK2 for the conveyance path to the holding box E2 at the output gate Gl. Also output game) G 2
The horizontal opening output TKl for the conveyance path to the holding box E1 is obtained at .

The verification circuit 11 includes NAND circuits G7 and G8 for abnormal verification, which correspond to the transport paths to the holding boxes E1 and E2, respectively, and NAND circuits G9 and GIO for normal verification, each having a similar configuration. The output pulse d2 of the detector D2 is applied to the circuits G7 and G9, the output pulse d3 of the detector D3 is applied to the circuits G8 and Glo, and the lateral opening outputs TK1 and TK2 of the force generating circuit 10 are applied to the circuits G7 and G8, respectively.
The signals are also applied to circuits G9 and GIO through inverters (3) and (4), respectively.

The outputs of the circuits G7 and G8 are outputted as the miss detection signal ER via the output gate G11, and the Q output of the circuit F1 of the generation circuit 10 described above is outputted as the miss detection signal ER via the output gate G11.

On the other hand, the output of the link G9 and GIO is output from the output gate G12.
is applied to the differentiating circuit DF3 via the differentiating circuit DF3.
At step 3, when the output is obtained from the circuit G9 or GIO, a differential pulse df3 is obtained, and this is output as a normality detection signal.

This normality detection signal is applied to flip-flop circuits F2 and F3.
is applied to the reset input terminal R of.

In the above-mentioned configuration, if the guide plate A is in the counterclockwise rotation position and the conveyed coins C are being normally conveyed through the conveyance path to the holding box E2, then at time tx. When the currency C starts passing through the detector D1 position, an output pulse d1 is outputted as shown in FIG. 3 d1.
As a result, as shown in FIG. 3 df1, the button is pressed at time t1 and a pulse df is obtained in the differentiating circuit DF1.

At this time, the circuit F2 is in the reset state as shown in FIG. 3 F2, and the gate G3 is therefore in the closed state, so the circuit F1 remains in the reset state.

Thereafter, when the pulse d1 falls at time t2, the differential circuit DF2 generates a differential pulse df2 as shown in FIG. 3 df2.
is obtained, and thereby the circuit F2 is set as shown in FIG. 3 F2.

Gates G3 and G4 are therefore open after time t2.

When the button is pressed at time t3 after sono and the switching output O8 of "H" level is outputted from the generation circuit O8 as shown in FIG. 3 os,
This is the circuit F as shown in Figure 3 F3 via G4.
Set 3.

Thus, the output game (G) corresponding to the conveyance path to the holding box E2
1 is in the open state.

Thereafter, at time t4, the button is pressed and the generating circuit p is activated as shown in FIG. 3 p.
When an output pulse p is obtained, this is inverted by the gate G1 as shown in FIG.
8 and is inverted again by inverter 4 as shown in FIG.
It is given as K2 to the normal verification circuit G1o.

After that, the button is pressed at time t5, and when the coin C starts passing through the detector D3 position via the conveyance path to the holding box E2, at this time r
3rd in normal verification circuit GIO with HJ level input
An output glO as shown in FIG.
3 resets circuits F2 and F3.

Eventually, at time t6, the output pulse P of the generating circuit P falls, and the system as a whole returns to its original state, waiting for the next feeding of degenerate coins to the transport mechanism 1.

In this way, under normal conditions, the normal transport time of the transported currency C is approximately equal to the delay time of the delay circuit T, so the output pulse d3 generated by the detector D3 when the transported currency C passes the detector D3 position. occurs within the duration τ2 of the pulse p generated by the generating circuit p, while the detection output from the corresponding detector d3 for the circuit G8 and GIO selected by the switching output os of the transport path d3 has occurred, and based on these two conditions, the verification circuit 11 determines that there is no abnormality in the transport mechanism 1.

On the other hand, if there is an abnormality in the ψ conversion operation of the conveyance path,
It will look like this:

That is, in the above description of the normal operation, if the conveyed currency C is erroneously conveyed to the conveyance path to the holding box E1, the third
As shown in the figure, between time points t4 and t6, the horizontal open output TK1 given from the generation circuit 10 to the abnormality verification circuit G7 is [(j, so when the detection pulse d2 is obtained at the detector D2, , immediately the error detection signal ER is output from G7 via Gll.

Further, the conveyance error detection device of this embodiment can detect the following conveyance errors in addition to the above-mentioned conveyance errors such as an abnormality in the switching operation.

First, if a slip occurs in the transport mechanism 1 and the output pulse d3 of the detector D3 does not occur between the set times t4 and t6, but occurs at a time t7 after the time t6, at this time, the verification circuit G8 Since the inputs to G1 and G1° have already been inverted, the inputs from circuit G8 to G1 as shown in FIG.
A mistake detection signal ER is outputted via 11.

At this time, no output is obtained from circuit G12, so circuits F2 and F3 are not reset.

Such operation is illustrated by dotted lines in FIG.

Furthermore, if a blockage occurs in the conveyance mechanism 1 and the currency C cannot be sent to the holding box E2, the paths F2 and F3 remain set after time t66, as in the case of the first abnormality.
This leaves gates G3 and G4 open.

In this state, the coins following the jammed coins are fed into the conveyance mechanism 1, so that the next output pulse d is generated by the detector D1.
When l is obtained, the differential pulse di1 obtained by the differentiator circuit DPI at the time of its rise is sent to the circuit Fl via G3.
Set.

Therefore, at this time, the four outputs [, J] are outputted as the error detection signal ER through the output gate G11 of the matching circuit 11.

In this case, the circuit F1 is reset by, for example, a manually generated reset signal R8.

In addition, when a plurality of coins are fed into the conveyance mechanism 1 while overlapping each other in a mutually shifted state, the output pulse d of the detector D3
3 rises, for example, at time t5 in Fig. 3, the pulse width corresponds to the total length of the overlapping coins, so the output pulse d3 of the detectors I The falling point is after the time t6 when the output pulse p of the generating circuit p falls.

However, since the horizontal open output TK2 of the circuit 10 for the abnormality checking circuit G8 inverts the rHJ level after time t66,
Eventually, after time t66, the error detection signal ER is output from the path G8 through the path Gll.

If the transported coin C is a damaged coin and has cracks, holes, etc., the output pulse of the detector D1 (d1 in FIG. 3) will be divided into two or more thin pulses.

Therefore, since the circuit F2 is set at the falling edge of the first pulse among these divided pulses, the following second divided pulse sets the circuit F1 via G3.

Thus, in this case, the error detection signal ER is outputted from the collation circuit 11 by the four outputs of the circuit F1.

In addition, regarding the explanation of the above-mentioned operation, the transported currency C is placed in the holding box E.
Although we have described the case of transporting through the transport route to 2,
It is obvious that the same operation will be performed when conveying through the conveyance path to another holding box E1.

As described above, according to the embodiments shown in FIGS. 1 to 3, all kinds of possible conveyance errors can be reliably detected by pressing the button on the conveyance mechanism 1.

In the configuration shown in FIG. 2, the switching signal os from the switching signal generation circuit O8 is applied to the gate G4 to switch the transport path for each denomination.
A coin dispensing machine is equipped with a detector that detects the authenticity of coins, or a detector that detects damaged coins, and the detection signal is used to remove defective coins, or a coin dispensing machine that removes coins of the same denomination as planned. Money dispensing machines that sort money by amount, etc.
It can be applied to various money dispensing machines.

In this case, a detection signal, sorting signal, etc. may be applied to G4 instead of the switching signal os.

Furthermore, in the embodiment shown in FIG. 2, the case was described in which the transportation times to the holding boxes E1 and E2 were made to be approximately equal to each other, but they may be made to be different from each other. Circuit F3 of open signal generation circuit 10, gate Gl! G2
It is only necessary to change the other parts except G4 so that 22 sets are provided.

1,・r Furthermore, for the embodiment shown in FIG. 2, when the transport mechanism 1 is jammed with transport coins C, the passage of the next transport coin C is detected by the detector DI, and this detection output d1 is used. The circuit Fl is set to output the error detection signal ER, but instead of this configuration, the circuit F2 is reset even if a predetermined time has elapsed since it was set at the falling edge of the detection output di. If this is not the case, it may be assumed that a transport error has occurred, and the error detection signal ER may be generated. In this case, for example, a timer circuit activated by the Q output of the circuit F2 is provided, and its timing output is output to the output game). Output via Gll.

In this case, the differential circuit DF1 and gate G11 circuit F in FIG.
1 can be omitted.

As described above, according to the present invention, if the conveyed coin is mistakenly dispensed to a dispensing port other than the dispensing port corresponding to the denomination due to an abnormal switching operation of the conveying path, this can be extremely easily prevented. With this configuration, the reliability of the money dispensing machine can be further improved.
