Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a coin feeding stop device in a coin processing machine, and relates to a coin feeding stopping device for a coin processing machine, which is used in a coin counting machine, a coin sorting machine, a coin wrapping machine, etc. This relates to a device that stops feeding when the number of coins reaches a set number.

(Prior Art) In general, in this type of coin processing device, when counting the number of coins, a star-shaped counting wheel is placed on the coin path, and the counting wheel is sequentially set in a predetermined manner by coins passing on the coin path. It was configured to rotate at an angle. Then, the number of coins is counted based on the amount of rotation of this counting wheel, and when this number reaches a preset number, the feeding of coins is stopped. As this feeding stopping means, a hole is provided in a gear interlocked with the counting wheel, and a stopping plate is inserted into the hole to prevent rotation of the gear, thereby stopping rotation of the counting wheel and preventing coin feeding. It was hot.

However, it is impossible to increase the counting speed by rotating the star-shaped counting wheel by the coin itself.

Therefore, as shown in JP-A-51-134698, for example, a detection device that detects the passing of coins without contacting them, such as a proximity switch or a photo sensor, is used, and the device is placed facing the coin path. A system was devised that could detect the number of coins passing through the system. In this case, when the number of passing coins reaches a set number, a coin passage blocking member or the like is projected into the coin passage to stop the coins from being fed out.

(Problems to be Solved by the Invention) However, even with this configuration, the counting speed cannot be made very high. This is because, as mentioned above, when the number of detected coins reaches a set number, the coin passage blocking member is projected onto the coin path and stops the coin feeding.At this time, the passage of coins is stopped instantly. If the counting speed is high, the coins will go backwards due to the recoil. Then, since the coins are transported again to the coin passage blocking member by the conveyor belt or the like, the detection device generates a detection output again, which may result in erroneous counting.

In order to prevent this, it is possible to cut off the detection output and prevent the coins from being counted after the set number of coins has been reached, but if this is done, the operation of the coin passage blocking member will be delayed for some reason and the setting will be delayed. Even if more coins are sent out, this cannot be detected and the actual number of coins sent out cannot be known.

Furthermore, it is possible to reduce the conveyance speed and accurately stop the conveying speed by counting several sheets before reaching the set number, but this would require processing time and result in a decrease in performance.

The present invention has been made in view of the above-mentioned points, and enables accurate feeding of coins at a high counting speed, and even if the coins are not fed out reliably, the coins actually sent out can be It is an object of the present invention to provide a coin feeding stop device in a coin processing device that can confirm the number of coins.

[Structure of the invention]

(Means for Solving the Problems) The coin feeding stop device in the coin processing device of the present invention is arranged in sequence along the conveying device 20 for conveying the coins 12 on the coin passage 14 and the conveying direction of the coins 12. First and second detection devices 25, 2 each producing a detection output each time a coin 12 passes.
6, a first counting and comparison device 35 that counts the detection output of the first detection device 25 and outputs a coincidence signal when the detected output reaches a preset value, and the first and second detection devices 25 and 26. A coin passage blocking device 28 is provided between the coin passage blocking device 28, which is operated by a coincidence signal from the first count comparison device 35, and blocks passage of the coin 12; A counter disabling circuit 39 that disables the detection output of the first detection device 25 and a counting invalidation circuit 39 that counts the detection output of the second detection device 26 and, when the detection output of the second detection device 26 reaches the same set value as the first count comparison device 35, the transfer device 2
It is equipped with a second count comparison device 42 that generates an output signal to stop zero, and a display 44 that displays the count value counted by the second count comparison device 42.

(Function) When the count value of the first detection device 25 reaches a set number, the coin feed stop device in the coin processing device of the present invention operates the coin passage prevention device 28 and outputs the detection output of the first detection device 25. is made uncountable, and the number of coins 12 actually sent out is displayed based on the detection output of the second detection device 26, and when the count value of the second detection device 26 reaches the set number, the conveying means 20 is stopped.

(Example) Hereinafter, the configuration of an example of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 11 denotes a rotary disk for sending out coins, and its rotation causes coins 12 thrown in from a hopper (not shown) to be sequentially arranged along a regulating plate 13 provided around the circumference by centrifugal force. Then, the coins are fed into one piece in the thickness direction onto the coin passage 14 outside the rotary disk 11 via a guide member (not shown).

The coin passage 14 is for arranging the coins 12 sent out from the rotary disk 11 in a line, and is composed of a fixed guide plate 15 and a movable guide plate 16 arranged in parallel. Shoulder portions 15a and 15b are formed over the entire length of the opposing sides of both guide plates 15 and 16, respectively, and the coin 12 moves on these shoulder portions 15a and 16a. Therefore, coins having a smaller diameter than the opposing distance between the shoulders 15a and 16a fall from above the coin passage 14. Further, the movable guide plate 16 is configured to be movable in a direction perpendicular to its length direction in order to change the distance from the fixed guide plate 15, and is always moved in the enlarged direction, that is, to the right in the figure, by means of a spring or the like (not shown). I receive strength from someone. and,
18 is a cam plate for setting the interval, which is connected to the movable guide plate 1.
The rotation of the movable guide plate 16 moves the movable guide plate 16 according to the height of the cam ridge, and sets the distance between the movable guide plate 16 and the fixed guide plate 15 arbitrarily.

Further, 20 is a conveyance device, which includes pulleys 21 and 22 arranged at both ends in the length direction of the coin passage 14,
It is composed of a belt 23 stretched between these pulleys 21 and 22. Then, by rotating the pulleys 21 and 22 clockwise as shown in the figure by a drive mechanism such as a motor (not shown) and driving the belt 23 in the same direction, the coins 12 aligned in a line on the coin passage 14 are moved in the alignment direction. Convey it along the line toward the front in the figure.

Reference numeral 25 indicates a first detection device, and reference numeral 26 indicates a second detection device, which are sequentially arranged along the coin passage 14 in the direction in which the coins 12 are conveyed. These detection devices 25 and 26 generate detection outputs each time the coin 12 passes over the opposing coin path 14. Although various detection devices 25 and 26 are possible, a proximity switch is used in this embodiment.

Reference numeral 28 denotes a coin passage blocking device, which includes a blocking rod 2 disposed between the first and second detection devices 25 and 26.
9 and a solenoid 30 that drives this blocking rod 29.
It consists of Here, the blocking rod 29 has an intermediate portion rotatably attached near the side of the coin passage 14,
Moreover, the lower end is connected to the plunger 31 of the solenoid 30. Accordingly, the plunger 31 rotates counterclockwise in the drawing due to the suction operation caused by the excitation of the solenoid 30, and its tip protrudes onto the coin passage 14 to prevent the coin 12 from passing through, that is, from being fed out. Note that when the solenoid 30 is not energized, the tip of the blocking rod 29 escapes from the coin passage 14 by a spring or the like (not shown).

Next, the configuration of the control circuit will be explained with reference to FIG.

In the figure, 35 is a first count comparison device, which inputs the detection output from the first detection device 25,
The fall of the coin, that is, the first detection device 25
The point at which the object passes through is captured and counted. Then, this counted value is compared with a value preset by a separate sheet number setting device 36, and if the two match, a match signal _a1 is generated. The output terminal of this first count comparison device 35 is connected to the input terminal of the solenoid drive circuit 37, and therefore, the solenoid drive circuit 37
The solenoid 30 is activated by the coincidence signal _a1 generated by the counting comparison device 35, but once the coincidence signal is
When _a1 is input, the solenoid 30 is kept energized until a start command c, which will be described later, is input. Although not shown, the number of sheets setting device 36 uses a numeric keypad provided on the operation desk to set the number of sheets, or to set one of a plurality of preset sheet values. The selection may be made using a number setting knob or the like.

Reference numeral 39 denotes a count invalidating circuit, which operates by inputting the coincidence signal _a1 from the first count comparator 35, and provides a reset signal b to the counting section of the first count comparator 35. The first count comparison device 35 sets the value of the counter to zero by inputting the reset signal b, and also causes the first detection device 25 to generate a detection output while the reset signal b is input. The system is configured so that the counting is not performed. The reset signal b generated by the counting invalidation circuit 39 continues until a start command c from a start command device 40, which will be described later, is input.

Reference numeral 42 denotes a second counting/comparing device which inputs the detection output of the second detection device 26 and counts the falling edge thereof. Then, while outputting the count signal d, this count value and the number setting device 3
6, and if they match, a match signal _a2 is output. Here, the count signal d is applied to the display drive circuit 43,
The signal is output to the display 44 as a numerical display signal. Furthermore, the coincidence signal a ₂ is transmitted to the transport device 20 shown in FIG.
Used as a stop command. Furthermore, if the coins 12 sent out are to be wrapped by a wrapping mechanism,
It can also be used as a start command to the packaging mechanism.

As the start command device 40, for example, a push button switch is used, and its output signal, that is, the start command c, is applied as a reset signal to the solenoid drive circuit 37, the count invalidation circuit 39, and the second count comparator 42, respectively.

Next, the operation of this embodiment will be explained.

When the start command device 40 shown in FIG. 2 is turned on, an operation control circuit (not shown) operates to rotate the turntable 11 shown in FIG.
Activate the transport device 20. For this reason, the coins 12 supplied onto the rotary disk 11 from a hopper (not shown)
are aligned by the regulating plate 13 and guided into the coin passage 14 as one sheet in the thickness direction by a guiding member (not shown). In the coin passage 14, a fixed guide plate 15 and a movable guide plate 16 are set at a predetermined interval from a cam plate 18, and coins 12 having an outer diameter approximately equal to or smaller than this interval are fed onto the coin passage 14. It will be done. Then, this coin 12 is conveyed along the coin passage 14 by the belt 23 of the conveying device 20,
Only coins having an outer diameter approximately equal to the distance between the guide plates 15 and 16 are sent out toward a coin box or coin wrapping mechanism (not shown) provided at the end of the coin passage 14.

When the coin 12 is sent out, the first and second detection devices 25 and 26 generate detection outputs each time the coin 12 passes through the opposing portions of the coin passage 14, and this is caused by the first and second detection outputs. count comparison device 35,
It is counted at 42. Here, the count signal d of the second count comparison device 42 is outputted to the display 44 via the display drive circuit 43, and the display number of the display 44 is updated every time the coin 12 passes, and the actual number of coins 12 is sent out. Display the number of sheets.

In this way, the coins 12 are counted sequentially, and the first
When the count comparison device 35 outputs the coincidence signal _a1 when it has counted the number of sheets set by the sheet number setting device 36, for example, 50 sheets (at this time, the display on the display 44 has not yet reached "50"). , this match signal
_A1 causes the solenoid drive circuit 37 to operate and keep the solenoid 30 energized. Therefore, the plunger 31 shown in FIG. 1 is attracted to the right in the drawing, rotates the blocking rod 29 counterclockwise in the drawing, and causes its tip to protrude above the coin passage 14 to prevent the coin 12 from being sent out. Further, the coincidence signal _a1 is applied to the count invalidation circuit 39, which gives a reset signal b to the first count comparator 35 to make the count value zero, and from then on until the reset signal b disappears.
Counting of the detection output from the first detection device 25 is disabled. Therefore, due to the reaction of the sudden blocking action of the blocking rod 29, the coin 12 returns once and moves to a position facing the first detecting device 25 again, so that the first detecting device 25 generates a detection output. However, since this detection output is not counted, the count value of the first count comparison device 35 will not become an incorrect value.

After the coincidence signal a ₁ is output from the first count comparison device 35, the coincidence signal a ₂ is output when the second count comparison device 42 counts 50 sheets set by the sheet number setting device 36. arise. By outputting this coincidence signal _a2 , the conveyance device 20 shown in FIG. 1 is controlled to stop, and, for example, the wrapping operation of the coin wrapping mechanism is started.

Here, as mentioned above, the second count comparison device 4
2, the display 44 displays the actual number of sheets to be sent out (currently "50" is displayed).
Even if the operation of the blocking rod 29 is delayed and more coins 12 than the set number of coins 12 are sent out (that is, the 51st or more coins 12), this can be reliably recognized by the number of coins 12 displayed on the display 44, and the coins 12 are not sent out. Post-processing such as removing more than a set number of coins 12 from among the collected coins 12 can be facilitated.

Next, when restarting, the start command device 40 is turned on again. By this operation, a start command c is applied to the counting invalidation circuit 39, canceling the reset signal b and restoring the counting function of the first counting comparator 35. Further, the start command c is applied as a reset signal to the solenoid drive circuit 37 and the second count comparison device 42, and returns them to their initial states. Then, the rotary disk 11 is rotated by the aforementioned operation control circuit (not shown), the conveyance device 20 is activated, and the same operation as described above is repeated.

Note that the restart command is given by the start command device 40 as described above, but for example, there are a plurality of gold boxes that receive sent coins, and after storing a set number of coins in one gold box, the restart command is given by the start command device 40. If coins are to be sent out continuously by switching the path or moving the gold box, this path switching completion signal or gold box movement completion signal may be used as a restart command. Further, in a coin wrapping machine, a signal obtained when the wrapping mechanism returns to a predetermined position is used as a restart command.

Next, another embodiment shown in FIG. 3 will be described. In addition, parts corresponding to those in Fig. 2 are given the same reference numerals.
The explanation will be omitted.

This embodiment simplifies the comparator circuit of the second count comparator 42 and also provides a function to detect failures of the coin passage blocking device 28 shown in FIG. 1. That is, the second counting comparison device 42 includes a second counting circuit 42A that counts the detection output of the second detection device 26, and a second counting circuit 42A that counts the detection output of the second detection device 26.
A “0” or “5” detection circuit 42B that generates an output signal when the last digit of the count signal d (decimal) output from A is “0” or “5”, and an output signal of this detection circuit 42B. is used as one input, and the AND gate 42c has the output of the solenoid drive circuit 37 as the other input. Here, the above "0"
Alternatively, the reason why the "5" detection circuit 42B is used is that the last digit of the coin number setting value is usually not set to a number other than "0" to "5". Also,
For coin wrapping machines, the set number is 50, for example.
This is because the numbers are usually multiples of 5, such as 1, 40, and 25. This “0” or “5” detection circuit 4
2B, as mentioned above, it is only necessary to compare whether the last digit of the count signal d is "0" or "5", so compared to the case where all the digits of the count signal d are compared, the comparator circuit is significantly required. Can be simplified. Then, by ANDing the output signal of the detection circuit 42B and the output signal of the solenoid drive circuit 37, a coincidence signal a ₂ is obtained as the second count comparison device 42.
is obtained. This coincidence signal _a2 is used to control the stop of the conveyance device 20 and, for example, to control the start of the packaging mechanism.

Further, 48 is a failure detection device, which includes an inverter 49 that inverts the output signal of the "0" or "5" detection circuit 42B, and the solenoid drive circuit 37.
It consists of a delay circuit 50 for delaying the output signal of 49 and 50 for a certain period of time to synchronize it with the second counting/comparing device 42 side, and an AND gate 51 which uses the output signals of both 49 and 50 as input conditions.

Next, the operation of the embodiment shown in FIG. 3 will be explained.

When the number of coins 12 to be delivered reaches a set value, for example 50 coins, a coincidence signal _a1 is generated from the first count comparison device 35, and the solenoid 30 is energized via the solenoid drive circuit 37, causing the coins to pass as shown in FIG. Blocking device 2
The operation up to the operation of 8 is the same as in the previous embodiment. Here, the output signal of the solenoid drive circuit 37 is applied to one side of the AND gate 42c. Therefore, after this, the count value of the second counting circuit 42A becomes 50.
(If cumulative counting is performed, 100 coins if the coin is sent out for the second time, 150 coins if it is the third time, etc.), and the "0" or "5" detection circuit 42B generates an output signal. and AND gate 42C conducts,
A coincidence signal a ₂ is produced as a second counting comparator 42 . By outputting this coincidence signal _a2 , the transport device 2
0 stops and, for example, in a coin wrapping machine, coin wrapping starts. Further, the output signal of the solenoid drive circuit 37 is applied to one side of the AND gate 51 via the delay circuit 50 as described above for failure detection. Here, the reason why the delay circuit 50 is interposed is as follows.
At the time when the output signal of the solenoid drive circuit 37 is generated, the count value of the second counting circuit 42A is still "49", and if the output signal is applied to the AND gate 51 at this point, the AND gate 51 will malfunction. This is to delay the time until the count value of the second counting circuit 42A reaches "50". Therefore, if each part of the device shown in FIG. 1 is normal, the count value of the second counting circuit 42A will be "50" at the time when the output signal is generated from the delay circuit 50, and the detection circuit 42B will output the output signal "50". 1'', the AND gate 51 is not conductive and the failure detection signal e
does not occur.

The case where the feed is restarted after stopping is the same as described in the previous embodiment. however,
If you want to display the total number of sheets sent, the second counting circuit 42A should not be reset by the restart command c, and the second counting circuit 42A should be reset by another command c'. good.

On the other hand, if the operation of the coin passage blocking device 28 shown in FIG. ”
The output signal of the detection circuit 42B becomes "0". Therefore, the AND gate 51 becomes conductive and outputs the failure detection signal e. In this case, since the AND condition of the AND gate 42c is no longer satisfied, the coincidence signal _a2 as the second count comparison device 42 also disappears, and no coin wrapping operation is performed in the coin wrapping machine. Of course, if the failure detection signal e is obtained, the coincidence signal
The conveying device 20 is stopped even if _a2 is not obtained. Furthermore, this failure detection signal e is used to cause a failure display, alarm, etc. to be given as appropriate.

Since the failure detection signal is output in this way, it is possible to more accurately notify a failure of the device, and it is also possible to reliably prevent the coin wrapping machine from wrapping the wrong number of coins.

In the above explanation, the set number of coins was set at 50, but this means that the number of coins wrapped in a coin wrapping machine in Japan, that is, the number of coins included in one coin roll, is determined regardless of the gold rights. This is because the number of sheets is constant at 50 pieces. Of course, in foreign countries, the number of packages may vary depending on the gold rights, and even the same gold rights may have different numbers of sheets, such as 40 pieces or 25 pieces. In such a case, as described above, the desired number of sheets can be set using the numeric keypad, the sheet number setting knob, or the like.

Further, in each of the embodiments described above, proximity switches are used as the first and second detection devices 25 and 26, but other non-contact detection devices such as photo sensors may be used. Furthermore, the counts in the first and second count comparators 35 and 42 may be addition or subtraction. Further, although the belt 23 is used as the conveying device 20, it may be one in which a plurality of rollers are lined up.In short, any device that conveys coins may be used.

〔Effect of the invention〕

According to the present invention, when the count value by the first detection device reaches a set value, the coin passage prevention device is activated and the detection output of the first detection device is made uncountable, so that the coins are collected in a preset number. Even when the coin dispensing is stopped, it is possible to accurately dispense coins at a high counting speed, and erroneous counting can be reliably prevented, and the counted value by the second detection device is the same as that by the first detection device. Since the conveyance means stops when the set value is reached, even if the coin passage blocking device is delayed in operation, malfunctions, malfunctions, etc., it will continue to send out more coins than the set value from the coin path. In addition, even if the dispensing is not stopped reliably, the number of coins actually dispensed can be accurately determined by looking at the display that displays the counted value by the second detection device. This allows for easy post-processing.
