Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a counting control device for a coin wrapping machine that prevents erroneous counting of coins.

[Prior Art] A coin wrapping machine automatically wraps coins in groups of, for example, 50 coins after counting them, and is mainly used in banking and other operations.

By the way, in this coin wrapping machine, if the coins are not aligned or the coins are over-counted,
Coins other than those that have been stacked and packaged in a predetermined number are rejected into a rejection box.

[Problem that the invention seeks to solve]

However, with the above-mentioned coin wrapping machine, there is a problem in that the value of the total counter that counts the total number of wrapped coins and coins in the middle of wrapping differs from the total number of coins that are actually wrapped or in the middle of being wrapped. occurred.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin wrapping machine that can completely grasp the number of coins that have been wrapped and are being wrapped when the coins are removed to a rejection box.

[Means for solving problems]

Therefore, the present invention provides a counter that counts the number of coins supplied to the coin stacking cylinder separately from the conventional total counter, and furthermore, makes both counters capable of adding and subtracting, and when the above problem occurs, , the supply of coins is immediately stopped, and a subtraction pulse is sent to the total counter and the counting counter at the same time, and subtraction is performed until the value of the counting counter becomes "0".

[Effect]

The coin wrapping machine configured as described above simultaneously performs coin removal processing and total counter subtraction processing, thereby making the count data of the total counter match the actual count value, regardless of the state. It is also possible to fully grasp the number of coins.

〔Example〕

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

FIG. 1 is a perspective view showing the main parts of one embodiment.
In the figure, reference numeral 1 is a rotating plate on which coins such as 100 yen coins are placed. This rotary plate 1 rotates in the direction of arrow A and sequentially introduces coins into the passage 2 side. A guide belt 3 is disposed above the passage 2 and rotates in the direction of arrow B while coming into contact with coins introduced into the passage 2. This guide belt 3 moves the coins in the direction of arrow C and supplies the coins to the coin stacking cylinder 4. Also, on the side of the passage 2, photo sensors 5a, 5b,
A stop shaft 6 is provided.

The photo sensors 5a and 5b receive light from light emitting diodes (not shown) disposed above them, and detect coins introduced into the passage 2 by blocking this light. be. The stop shaft 6 is rotatably attached to the passage 2 and is driven by a rotary solenoid 7 to open and close the passage 2 to stop or supply coins to the coin stacking cylinder 4.

The coin accumulating cylinder 4 is for accumulating coins supplied from the passage 2 side, and a shutter 8 is disposed at the bottom thereof. The shutter 8 is opened by moving a lever 8a in the direction of arrow D using an electromagnetic solenoid (not shown), etc., and the coins in the coin accumulation tube 4 fall from the bottom onto the coin support lever 9. There is.

Further, holes 10a and 10b are formed in the side wall surface of the coin accumulating tube 4, facing upward at a predetermined height from the shutter 8 provided at the bottom of the coin accumulating tube 4. are a light emitting diode 10c, a phototransistor 10d, etc. (not shown)
is installed. These light emitting diodes 1
0c, the phototransistor 10d is the coin accumulating tube 4
This is to detect irregularities in the coins in the coins.

In this way, when a predetermined number of coins are evenly stacked in the coin stacking tube 4, the shutter 8 is opened and a predetermined number of stacked coins are dropped onto the holder 9a of the coin support lever 9. A predetermined number of stacked coins are gradually lowered while the coin support lever 9 maintains this state, and are positioned between the wrapping rollers 11, 11, 11.

The wrapping rollers 11, 11, 11 are arranged radially from the axis E of the coin stacking cylinder 4 and are arranged movably in the direction of the axis E. These wrapping rollers 11, 11, 11 can pinch a predetermined number of coins stacked on the pedestal 9a while rotating in the direction of arrow F.
A wrapping paper 12 is interposed between the coin and the coin on the holder 9a to wrap the coin.

On the sides of these packaging rollers 11, 11, 11, paper feed detection sensors 13a, 13b, a cutter 14, and a paper feed roller 15 are sequentially arranged.

The paper feed roller 15 feeds the wrapping paper 12 held between the paper feed roller 15 and the pinch roller 16 in the direction of arrow H along a curved guide plate (not shown), and is driven by a drive mechanism (not shown) to a predetermined direction. It is sequentially rotated in the direction of arrow I in accordance with the timing of . Further, the rotation speed of the paper feed roller 15 is set lower than the rotation speed of the wrapping rollers 11, 11, 11, and the wrapping paper 12 is
A predetermined number of coins rotatably held by 1, 11, and 11 are wrapped tightly around each other with a constant tension. snow,
Wrapping paper 12 of a length suitable for the coin is cut and supplied.

The paper feed detection sensors 13a and 13b are constituted by photo sensors such as light emitting diodes and photodiodes, or ultrasonic sensors, and are arranged so as to sandwich the path through which the wrapping paper 12 passes. And paper feed detection sensor 13a, 1
3b is provided to determine whether or not the wrapping paper 12 is cut within a certain period of time after the supply starts at a predetermined timing.If the wrapping paper 12 is cut within this certain period of time, the wrapping paper 12 is temporarily cut. is no longer detected by the paper feed detection sensors 13a and 13b, and thereby the cutting of the wrapping paper 12 is detected. Moreover, after the cutting of the wrapping paper 12 is detected,
The leading end of the wrapping paper 12 is fed out to the positions of paper feed detection sensors 13a and 13b for the next wrapping.

By the way, the cutter 14, the paper feed roller 15, and the pinch roller 16 are integrally configured to be movable in the direction of arrow G (direction in which they can move forward and backward with respect to the packaging rollers 11, 11, 11). 1
2, the length corresponding to the coin diameter is reliably supplied. Thereafter, both ends of the predetermined number of coins wrapped around the wrapping paper 12 are crimped by a crimping mechanism (not shown) to become wrapped coins. Then, the coin support lever 9 moves to the J state, and the wrapped coins are guided by the gate 17 and fall into the storage box 18 side. This gate 17 is the axis 1
It is pivotably supported by 7a. A crank lever 17b is fixed to one end of the shaft 17a, and an operating piece 17c such as an electromagnetic solenoid (not shown) is pivotally attached to the tip of the crank lever 17b. 17c moves in the direction of arrow K and
7 in the direction of arrow L.

In this coin wrapping machine, during the above-mentioned series of operations, if a predetermined number or more of coins are supplied to the coin stacking tube 4, or if the coins in the coin stacking tube 4 become uneven, or if the coins are When the feeding is not performed normally, the gate 17 is rotated in the direction of arrow L to drop the defective coins to the rejection box 19 side.

FIG. 2 is a block diagram of a control circuit that controls various drive mechanisms based on signals from the various sensors shown in FIG. In the figure, reference numeral 31 is a coin detection section. The coin detection section 31 converts the signals from the photo sensors 5a and 5b into binary logic level signals and sends them to the addition/subtraction determination section 32.

The addition/subtraction determination section 32 sends a counting pulse to the total counter 33 and the counting counter 34 every time a coin passes. That is, the addition/subtraction determining section 32 sends out an addition counting pulse when the guide belt 3 moves the coin in the passage 2 in the direction of arrow C, and also when the guide belt 3 reverses and moves the coin in the direction opposite to the direction of arrow C. , a subtractive count pulse is sent to the total counter 33 and the counting counter 34 via the OR gate 35.

The total counter 33 adds up the wrapped coins and the coins being counted. This cumulative result is sent to the display unit 36 and displayed on an LED or the like.

The counting counter 34 counts the coins supplied to the coin accumulating cylinder 4, and sends the counting result to the comparison coincidence detection section 37 and the overcount detection section 38. Further, all zero information of this counting result is sent to the subtraction pulse generating section 39. The total counter 33 and the counting counter 34 are constructed by cascading a plurality of 4-bit type ICs capable of up-counting or down-counting, for example.

The comparison match detection section 37 and the count over detection section 38 are constructed by cascading a plurality of 4-bit type IC comparators and the like. The output of the counting counter 34 is input to one input terminal group, and the output from the counting number setting section 40 is input to the other input terminal group. When the count of the counting counter 34 and the number of coins to be counted set unit 40 match, the comparison coincidence detection unit 37 sends a coincidence signal to the counting stop device drive unit 43 and the coin feed motor drive unit 44 via OR gates 41 and 42, respectively. Send to. In this case, the counting stop device driving section 43 drives the rotary solenoid 45 to rotate the stop shaft 6 and close the passage 2. The coin feed motor drive unit 44 also operates a coin feed motor 46 that rotates the rotary plate 1 and the guide belt 3.
to stop. Note that a signal from the counting stop control section 47 is input to the other input terminals of the OR gates 41 and 42, and the counting stop control section 47 is connected to the coin detection section 3.
Based on the coin position information from 1, a power outage detection unit 48 or a stop signal is applied via the OR gate 49, and as a result, the rotary solenoid 7 prevents the coin from getting stuck on the passage 2. The stop shaft 6 is operated as follows.

The counting over detecting section 38 sends an over signal to the output selection gate 50 when the value of the counting counter exceeds the set number of sheets to be counted. The output selection gate 50 operates the display blinking operation control section 52 based on the selection signal from the counting/packaging selection section 51, and causes a display such as an IED in the display section 36 to blink.
One output is applied via the OR gate 53 to the subtraction pulse generator 39, the coin removal device drive unit 54, and the removal number counter 55.

The subtraction pulse generator 39 subtracts the total counter 33 and the counting counter 34 based on the output of the OR gate 53. The subtraction pulse is sequentially applied to the total counter 33 and counting via the OR gate 35 until the counting counter 34 becomes zero. It is sent to the counter 34. At the same time, the coin removal device drive unit 54
drives the gate switching solenoid 56 that rotates the gate 17 in the direction of arrow L, and also controls the shutter 8.
The shutter opening/closing solenoid 57 that opens the shutter is driven. After that, the coin removal device drive section 54 starts the restart signal generation control section 58, and the restart signal from the restart signal generation control section 58 is passed through the OR gate 59 to drive the counting stop device drive section 43 and the coin feed motor. The voltage is applied to the comparison match detection unit 3 through the OR gate 60.
7 and the count over detection section 38.
Note that a start signal or a next count signal is applied to the OR gate 59, so that the above operation is repeated. In addition, the next count signal is detected by the paper feed detection sensors 13a and 13b when the wrapping paper 1 is detected.
This is sent when disconnection of 2 is detected, and OR
The signal is applied to the clear terminal of the counting counter 34 via the gate 61. Note that the clear signal is used to set the initial state of this coin packaging machine, and is used to set the initial state of the coin wrapping machine.
4. Comparison match detection unit 37, counting over detection unit 3
8, furthermore, the guide belt 3 is driven in the reverse direction for a certain period of time by the coin feed motor drive unit 44, and the coin removal device drive unit 54
It is what drives the.

Further, the rejection number counter 55 instructs the alarm unit 62 to take out the coins in the coin rejection box 19 when the number of rejections exceeds a certain value. When a coin is removed from the coin removal box 19, a reset signal is automatically sent and the removal number counter 55 is cleared.

The main signals of the present invention are applied to the OR gate 53, and in addition to the above-mentioned over signal, irregularity detection is performed by a light receiving element and a light emitting element provided in the holes 10a and 10b of the coin stacking tube 4. A misalignment signal from the section and a paper feed failure signal are applied. That is, the misalignment signal has a configuration substantially similar to that of the coin detection section 31, and the coin misalignment detection section converts the signals from the light emitting diodes and phototransistors provided in the holes 10a and 10b of the coin stacking cylinder 4 into binary logic levels. (not shown), and when the coins in the coin stacking cylinder 4 become irregular, the light emitted toward the photo sensor provided in the hole 10b is blocked, so that the irregularity signal is " 1”. As a result, the coin wrapping machine repeats the above-described operation to remove the coins from the coin stacking cylinder 4 and subtracts the number of removed coins from the total counter 33.

The paper feed failure signal is sent when the leading end of the wrapping paper 12 is not properly guided between the stacked coins and the wrapping rollers 11, 11, 11, and therefore the wrapping paper 12 is not cut off by the cutter 14. It is something. That is, paper feed detection sensors 13a, 13b
Normally, the cutting of the wrapping paper 12 by the cutter 14 within a certain period of time after the supply of the wrapping paper 12 was started at a predetermined timing is detected by the fact that the wrapping paper 12 is no longer detected. If the paper cannot be cut out properly or the wrapping paper 12 cannot wrap the coin, the paper feed detection sensor 1
Even if 3a and 13b are removed after a predetermined time, the same wrapping paper 1
2 is detected, this detection signal is sent to the OR gate 53 as a paper feed failure signal.
Even when the paper feed is defective, the same operation as in the case of the irregular signal described above is performed.

Next, the operation of the above configuration will be explained.

First, when a start signal is applied to the OR gate 59, coins are sequentially stacked in the coin stacking cylinder 4. The coin detection unit 31 sequentially detects coins and sends the counting pulses to the total counter 33 and the counting counter 3.
Send to 4. When a predetermined number of coins are accumulated in the coin accumulation tube 4, the stop shaft 6 rotates to stop the supply of coins. When more than a predetermined number of coins are accumulated in the coin accumulation tube 4, the supply of coins is stopped and the shutter 8 is opened to remove the coins from the coin accumulation tube 4.
Close the shutter 8 again and start supplying coins.

If a predetermined number of coins in the coin accumulating tube 4 are out of order, the above operation is repeated, and if they are not out of order, a predetermined number of coins are moved to between the wrapping rollers 11, 11, 11 and wrapping is started. . In this case, if the paper feeding is not successful or if the wrapping paper 12 is not cut by the cutter 14, the above operation is repeated again and the wrapping rollers 11, 11, 11
Eliminate coins in between.

On the other hand, when coins are removed during the above series of operations, the number of removed coins is stored in the counting counter 34, and the subtraction pulse generator 39 continues to perform subtraction counting until the value of the counting counter 34 becomes zero. The pulses are sequentially passed through a total counter 33 and a counting counter 34.
Send to. When the value becomes zero, the counting counter 34 sends all zero information to the restart signal generation control unit 58 to start again.

〔Effect of the invention〕

As explained above, according to the present invention, when an irregularity of coins, an abnormality in paper feeding, and a count over are detected, the coins with the problem are removed and the number of removed coins is calculated from the total counter. Since it is subtracted, it is possible to calculate the cumulative total of the coins being wrapped and the coins that have been wrapped, and even if work is interrupted, the total number of coins can be accurately determined, speeding up the work. I can do it.

It goes without saying that the functions shown in the above block diagram can be implemented under CPU control.
