Description

[Detailed description of the invention] When managing a vending machine, it is often necessary to collect coins that have been inserted (so-called inventory operation). For this purpose, the administrator operates the built-in collection switch to dispense the coins accumulated in the change storage pipe using the coin dispensing device, and after collecting the appropriate number of coins or after the change storage pipe is empty. Recovery is performed by returning the recovery switch to the non-operating contact. There is a collection switch like this for each change storage pipe, so when collecting all the coins, the administrator should keep an eye on the change storage pipe and return the collection switch when it is empty and start another collection related to the next pipe. The work becomes very cumbersome as the switch must be operated. In addition, there are occasional work errors where the user forgets to reset the collection switch and leaves the vending machine in the customer waiting state while the switch is left in the operating state.In this case, the coin dispensing device continues to operate even though the change storage pipe is empty. Therefore, if it was an automatic replenishment type, the inserted coins would be paid out and no sales operation would occur.

In order to solve the above-mentioned problems, the present invention provides a device in which when change is collected and dispensed from a certain change storage pipe, the collection and dispensing operation is automatically started for the next change storage pipe, and the collection operation is automatically stopped when all collection operations are completed. It provides: Moreover, according to the present invention, a single automatic return type collection switch is provided, and the change storage pipe to be collected can be selected depending on the number of times the switch is operated.

An embodiment of the present invention will be described in detail below with reference to the drawings.
The figure shows the configuration of a coin pick that performs all operations related to coin processing in a vending machine.
Entrance 13, coin sorting section 14, change storage pipes 1, 2, 3 for each denomination, return passage 15 for coins determined to be counterfeit coins by coin sorting section 14, and coin sending devices 4, 5, 6.
It is composed of. In addition, change detection devices 9, 1
0 and 11 are provided corresponding to change storage pipes 1, 2, and 3, and determine the presence or absence of change based on the maximum number of change required for dispensing change in one sales operation (generally 10). ing. In the case of this example, the coin dispensing devices 4, 5, and 6 are provided for each of the change storage pipes 1, 2, and 3, but the coin dispensing devices 4, 5, and 6 may be commonly used to selectively dispense coins from each pipe.

The recovery switch 7 installed in the upper case of the return path 15 is an automatic return type, and the contact 1 is closed by pressing the switch.
6 is closed, an operating signal A is generated from the OR gate 17. Every time the operation signal A arrives, the collection control device 8 changes the initial state "00" and the change coin storage pipe 1,
It is composed of a two-stage counter and sequentially transitions through the collection states "01", "10", and "11" according to the numbers 2 and 3. And each status output of the recovery control device 8 is “01”
"10" and "11" are input as drive commands to the coin sending devices 4, 5, and 6, respectively, and the change storage pipes 1, 2,
AND gate 18, 1 provided corresponding to 3
9 or 20.
The other of the AND gates 18, 19, and 20 is configured to receive the high-level change detection force from the change detection devices 9, 10, and 11 as input, and the logical product output is passed through the OR gate 21 to the AND gate. 22. timer device
Twelve counters 23 perform a timer operation by counting reference pulses from a reference pulse generator 24 connected to the other side of the AND gate 22. Therefore, the timer operating time is set to a predetermined time period that is slightly longer than the time required to pay out all the remaining standard number of coins after the change detection device 9 detects that there is no change, and the decimal number of the counter 23 is set to the standard number. It is determined by the pulse period and this predetermined time. The carry output B of the counter 23 is connected to be input to the OR gate 17, and is reset by the "00" state output of the collection control device 8.

According to the above configuration, when the collection switch 7 is operated, the collection control device 8 transits from the initial state "00" to the collection state "01" by the operation signal A, and a driving command is given to the coin sending device 4, and the change storage pipe is 1 recovery operation and the AND gate 18 becomes conductive. When there are more than the reference number of change coins in the change storage pipe 1, the change detection device 9 does not generate a high level output, so the AND gate 22 does not output a reference pulse and the counter 23 does not perform a timer operation. However, when the change collecting operation by the coin sending device 4 causes the stored change coins to become less than the reference number, the change detecting device 9 outputs a high level output indicating that there is no change, the AND gate 22 outputs a reference pulse, and the counter 23 performs a counting operation. will start and the timer will operate. Even during the timer operation, the coin dispensing device 4 continues to perform the change collection operation, and after the reference number of change coins has been dispensed, the timer operation ends and a digit output B is generated. When the carry output B is input to the collection control device 8 via the OR gate 17, the collection state changes from "01" to "10" and the coin dispensing device 5
is driven and the change storage pipe 1 is collected.
When the number of change coins stored in the change storage pipe 2 is less than the reference number, an output is obtained to the AND gate 19 and the timer is activated. Similarly, when the digit output B is generated due to the end of the timer operation, the collection state changes from "10" to "11", the coin sending device 6 is driven, and the change storage pipe 3 is in a collection operation. When the number of change coins stored in the change storage pipe 3 is less than the reference number, an output is obtained from the AND gate 20 and a timer operation is performed, and an additional output B is generated when the timer operation ends.
The collection state changes from "11" to the initial state "00" and the collection operation ends. Furthermore, the counter 23 is reset by the "00" state output.

When collecting change coins from all the change storage pipes 1, 2, and 3 as described above, by operating the collection switch 7 once, the collection control device 8 changes and automatically collects coins from all the pipes sequentially. Can be stopped. If you want to collect change coins from a specific pipe, you can do so by operating the collection switch 7 a number of times according to that pipe. For example, if you want to collect change from only the change storage pipe 2, press the collection switch 7 twice to specify the collection operation, and after the collection of the pipe is finished and the state of the collection control device 8 becomes "11", press the collection switch again. All you have to do is press 7 once. In addition, if you want to stop the collection operation midway through leaving a certain number of coins equal to or greater than the reference number in the change storage pipe, if you operate the collection switch 7 at the appropriate time, the collection operation of the pipe concerned will be stopped and the collection operation of the next pipe will be started. can do.

〓〓〓〓〓
According to the present invention described in detail above, the change detection device is used to detect the completion of the collection operation by a timer device, and with a single operation of the collection switch, change coins are automatically removed from all change storage pipes. Since the machine dispenses and stops, operability when collecting change can be improved. Moreover, a single automatic return type collection switch is provided, and a specific change storage pipe can be designated by the number of operations, thereby simplifying the apparatus. By operating the same switch, you can also stop the machine midway, providing a wide range of change collection devices.
