Description

The present invention relates to an apparatus for counting the number of coins in a coin mechanism having a cassette type coin tube.

(B) Prior Art A coin mechanism arranged in a vending machine for performing operations related to coin processing is provided with a coin tube for holding coins for change. As the coin tube, a cassette type in which a coin tube main body is detachable from a coin mechanism in order to facilitate supply of change and maintenance and inspection of a coin dispensing mechanism is conventionally known. In order to detect the number of coins held in the coin tube, a counter is provided. With this counter, the number of inserted coins stored in the coin tube is added and counted, and the number of coins paid out from the tube is subtracted and counted. Conventionally, in the case of the above-mentioned cassette type, when the coin tube is removed and coins are manually collected or replenished, the number of coins held is not counted and the counter is not removed. However, there is a problem that the counting of the number of coins held is excessive or deficient because the contents of (1) are maintained.

For this reason, Japanese Utility Model Publication No. Sho 62-27945 discloses an attachment detecting means for detecting whether or not a coin tube is attached at a predetermined position, and based on the output of the attachment detecting means, when removing or attaching the coin tube. A configuration is shown in which the content of a counter for counting the number of coins held according to at least one of the times is initialized to a predetermined value.

(C) Problems to be Solved by the Invention According to the above-mentioned prior art, the content of the counter is initially set to a predetermined value when the coin tube is removed (or attached), so that the coin tube is removed. When the number of coins in the tube changes to “0” or an appropriate value other than “0” due to the collection of coins (and then manual replenishment), the contents of the counter are set to a certain initial value, Thereafter, the number of coins held in the coin tube can be effectively detected.

However, in this prior art, when the coin tube is removed or attached, the counter is always preset to a predetermined value.Therefore, when an operation other than adjusting the number of coin tubes held to this predetermined value is performed, the counter is not counted. The number of holdings goes wrong. For example, if the content of the counter is set to “10” when installing the coin tube, collect all the coins when removing the coin tube and re-attach the coin to “0”. Nevertheless, the count of the counter is “1”
When the coin tube is reattached without removing and replenishing the coin even if the coin tube is removed, the counter is counting the correct number of coins and the wrong number is displayed. Are preset.

Therefore, the present invention determines whether or not there is a coin in a coin tube when a coin tube is attached, and determines whether or not to perform presetting on a counter, and also determines the value when presetting the coins. An apparatus is provided.

(D) Means for Solving the Problems In order to solve the above problems, a coin counting device for a coin mechanism according to the present invention includes: a mounting detection device for detecting mounting of a coin tube on a coin mechanism;
Add the number of coins introduced into the coin tube,
A counter for counting the number of coins held by subtracting the number of coins paid out from the coin tube, and detecting the presence or absence of coins in the coin tube when the coin tube is attached to the coin mechanism. A coin detecting device, and a preset device that presets the counter based on a mounting signal generated by the mounting detecting device and the presence or absence of a coin by the coin detecting device based on the detection force. When the output of the coin detection device switches from a signal indicating the absence of a coin to a signal indicating the presence of a coin after the occurrence, the content of the counter is preset to a predetermined value, and after the occurrence of the mounting signal, the coin detection device is reset. Outputs a signal indicating that there is no coin, clears the contents of the counter, and before the occurrence of the mounting signal The coin detecting device after the fine generation is configured to hold the contents of the counter and outputs a signal indicating that there is a coin.

(E) Action After the coin tube is removed from the coin mechanism and all coins are collected and re-attached, when the attachment detection device outputs the attachment signal, the preset device detects that there is no coin Clear the contents of the counter to output the indicated signal. Also, when the coin tube is removed from the coin mechanism and refilled after coins are replenished to the specified number of holdings,
Before and after the mounting detector outputs the mounting signal, the output of the coin detector switches from a signal indicating the absence of a coin to a signal indicating the presence of a coin. Is preset by the counter. Then, although removed from the coin mechanism, neither replenishment nor recovery of the coin is performed, and if the coin tube is attached again with the coin present,
Before and after the generation of the mounting signal of the mounting detection device, the coin detection device outputs a signal indicating the presence of a coin. At this time, the preset device does not act on the counter, and in this case, the counter is the number of coin tubes held. Is held as it is.

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

In FIG. 1 and FIG.
Consists of a plurality of coin storage coin tubes 2 having openings at the upper and lower ends, and coins of different denominations are retained. These tubes 2 are juxtaposed and formed integrally.

At the lower part of the coin tube main body 1, a coin receiving stand 4 is provided which can be freely opened and closed with a pair of left and right pins 3, 3 attached near the entire lower surface on both sides. The coin receiving tray 4 can store a predetermined number of coins M.

Locking pieces 5a, 6a are provided on the left and right sides of the back of the coin receiver 4.
A pair of hooks 5 and 6 are attached so that they face each other inward.

A pair of left and right hook levers 7 and 8 provided with substantially L-shaped locking pieces 7a and 8a facing outward are provided with leaf spring washers 9 and 10 at the lower rear portion of the coin tube body 1. Mounted using. The hooks 7a, 8a of the hook levers 7, 8 made of an elastic member are attached to the hooks 5a,
Normally, the coin receiver 4 can be kept in a closed state by engaging with the coins 6a. When the coin receiving tray 4 is opened, the hook levers 7, 8 of the elastic member are pushed inward as shown by arrows in FIG. 2 to release the engagement with the hooks 5, 6.

Since the coin base 4 is provided at the lower portion of the coin tube main body 1 so that the entire base can be freely opened and closed, dirt on the base part due to coins can be easily cleaned by opening the coin base 4.

In addition, by providing the coin receiving tray 4, coins can be taken out from the lower side of the coin tube main body 1, so that the retrievability of coins is improved and the required amount of coins in the coin holding tube 2 can be taken out freely. Can be.

By the way, an opening 11 for dispensing change is formed below the coin holding tube 2 at a lower rear portion of the coin receiver 4, and a change dispensing mechanism can be operated at the bottom of the coin receiver 4. Groove 12 is formed in the front-rear direction. When paying out the coins held in the coin tube main body 1, the change payout plate 13 shown in FIG.
Is reciprocated in the direction of the arrow by using a driving force of a gear motor or a solenoid plunger, so that the coin located at the lowermost portion of the coin receiving tray 4 can be dispensed on the change dispensing plate.
13, the coin can be pushed out and discharged from the opening 11 having a height of approximately one coin.

Next, check if there is a coin in the coin tube 2,
That is, a coin detecting device 42 for detecting whether or not a predetermined number of coins are held in the coin receiving tray 4 will be described with reference to FIGS. Here, the predetermined number is
For example, in the case of setting the price in increments of 10 yen, if the change amount of at least 90 yen for the input of 100 yen is left in the coin receiving tray 4, it is possible to prepare for the next sales state. Equivalent to nine images. It is sufficient that the coin receiving tray 4 can store a slightly larger number of coins than the minimum change number.

In the rear wall surface of the coin receiver 4 closed at the lower part of the coin tube main body 1, through holes 21 are formed at coin holding positions corresponding to the predetermined number. Also, slider 22
By the action of a rotor 30 that converts the rotational motion of a gear motor (not shown) into a linear motion, for example, the rotor approaches or retreats in the direction of the plurality of coin tubes 2 arranged in parallel. The driving force of the rotor 30 is transmitted to the change dispensing plate 13 via the connecting member 31.

The detecting member 25 is a through hole 21 formed in the wall surface of the coin receiving tray 4.
Through the coin receiver 4. The detection member 25 has a base portion locked in the slider 22 and is supported by a spring. The slider 22 includes a switch that is biased by the detection member 25. When the slider 22 is moved closer to the coin tube main body 1, the detecting member 25 advances into the coin receiving tray 4, and when a coin is present in the coin receiving tray 4, the detecting member 25 comes into contact with the coin and the spring contracts due to the reaction. Therefore, the switch is turned on by the detection member 25. However, if there is no coin corresponding to the position where the detection member 25 advances, the switch is not turned on because the spring is not biased by the detection member 25. Like this slider 22
When the switch is brought close to the coin tube body 1
By determining ON or OFF, the presence or absence of a predetermined number of coins in the coin tube 2 can be accurately detected.

Next, a mechanism that makes the coin tube main body 1 detachable from a coin mechanism that performs all operations related to coin processing in a vending machine will be described with reference to FIG.

A pair of bosses 14 and 15 are vertically provided on the lower side of both side walls of the coin tube main body 1, respectively. Fitting grooves 17 and 18 are cut out on both side surfaces of the housing of the coin mechanism 16 so that the bosses 14 and 15 of the coin tube main body 1 can be fitted into the fitting grooves 17 and 18 or not. By unwinding, the coin tube main body 1 can be detachably attached to the coin mechanism 16. The coin mechanism 16 is provided with a switch 38 on the surface facing the mounted coin tube main body 1, and on the back of the coin tube main body 1 is provided with a projection 39 which engages with the switch when mounted. When the tube body 1 is mounted on the coin mechanism 16, the switch 38
Is turned on.

Furthermore, the coin mechanism 16 has a coin receiving port 35 at the top,
A coin discriminating unit 36, a change dispensing mechanism unit 37, and the like are provided below. After each coin tube 2 of the coin tube main body 1 has a coin discriminated by the coin discriminating unit 36,
Automatic replenishment is provided.

FIG. 6 is a block diagram showing a circuit configuration of one embodiment for achieving the coin holding number counting operation in the coin mechanism 16 having the above configuration. The counter 40 is provided for each coin tube 2, but only one counter is shown in FIG. Then, the counter 40 adds and counts the insertion signal 44a generated in the inserted coin detector 44 when a coin is introduced into the corresponding coin tube 2, and when the change dispensing mechanism 37 pays out coins from the coin tube 2. The number of coins in the coin tube 2 is counted by counting the payout signal 37a outputted to the coin tube 2. When the coin tube main body 1 is mounted on the coin mechanism 16 and the switch 38 is switched from OFF to ON, the mounting detection device 41 gives a mounting signal 41a to the coin detecting device 42 and the preset device 43. It is composed of a vibrator. The coin detecting device 42 is driven by the input of the mounting signal 41a to perform the coin detecting operation in the coin tube 2, but is controlled not only by the mounting signal 41a but also by the control unit 45 of the vending machine to appropriately perform the coin detecting operation. It is supposed to do it. The control unit 45 controls each unit of the vending machine including the change dispensing mechanism unit 37 based on the number of coins counted by the counter 40 and the detection signal of the coin detection device 42, but attaches the coin tube body 1 to the coin mechanism 16 If the switch is incomplete and the switch 38 is OFF, the control operation of the vending machine is stopped. The preset device 43 is a mounting signal 41a.
Is input, the preset of the counter 40 is controlled in accordance with the presence or absence of a coin in the coin tube 2 indicated by the coin detecting device 42.

When the output of the coin detecting device 42 switches from a signal indicating that there is no coin to a signal indicating that there is no coin after the generation of the mounting signal 41a, the preset device 43 indicates to the counter 40 that “1” has been set.
When the coin detection device 42 outputs a signal indicating that there is no coin after presetting “0” and generating the mounting signal 41a, the counter 40 is cleared. Therefore, the preset device 43
If the coin detection device 42 does not continuously output a signal indicating the presence of a coin before and after the generation of the mounting signal 41a, the counter 40 is not preset, and the counter 40 counts the number of coins counted at that time. It will be kept as it is.

FIG. 7 shows a specific example of the preset device 43, in which the coin detecting device 42 outputs a signal 42a indicating that there is no coin.
Is introduced to the set end S of the flip-flop 46, and the signal 42b indicating the presence of a coin is introduced to the reset end R of the flip-flop 46 via the delay circuit 47. The AND gate 48 includes the mounting signal 41a, the signal 42b, and the flip-flop 46.
When a logical product is obtained with the output of (i), a signal is given to the preset data output circuit 49. By inputting this signal, the preset data output circuit 49 sets “10” in the counter 40 as preset data. The AND gate 50 outputs a clear signal to the counter 40 when a logical product is obtained between the mounting signal 41a and the signal 42a. Such a preset device 43 includes a control unit
When 45 detects the presence or absence of a coin in the coin tube 2 by appropriately driving the coil detection device 42, this is stored in the flip-flop 46. Therefore, the coin tube body 1
Immediately after is removed from the coin mechanism 16 and mounted again, the flip-flop 46 holds data indicating the presence or absence of a coin in the coin tube 2 before mounting. When the coin detection device 42 is driven by a mounting signal 41a generated by mounting the coin tube main body 1,
The signal 42a or the signal 42b is output according to the presence or absence of the coin. When the signal 42a is output, a clear signal is generated in the AND gate 50, and the counter 40 is cleared. When the signal 42b is output, a signal is obtained at the AND gate 48, and the counter 40 is preset to "10" by the preset data output circuit 49. This signal 42b is input to the reset end of the flip-flop 46 after the delay time of the delay circuit 47 has elapsed, whereby the flip-flop is inverted and the coin tube 2
Memorizes that there is a coin. In addition, the coin detecting device 41 is driven by the coin detecting device 42,
Loading signal 41 for a period sufficient to detect the presence or absence of coins inside
It is set to output a.

(G) Effect of the Invention According to the present invention, the preset device switches the output of the coin detection device from a signal indicating that there is no coin to a signal indicating that a coin is present after the generation of the mounting signal generated in the mounting detection device. When replaced, the contents of the counter are preset to a predetermined value,
When the coin detection device outputs a signal indicating that there is no coin after the generation of the mounting signal, the contents of the counter are cleared, so the coin tube is removed and the coin is replenished and then mounted. In any case, no replenishment or collection is performed, and before and after the generation of the mounting signal, the coin detection device outputs a signal indicating the presence of a coin without changing the contents of the counter. It can be kept as it is. Therefore, even if the coin tube has a configuration in which a plurality of coin tubes are juxtaposed and integrated, and the processing of replenishment or collection differs for each coin tube when the coin tubes are removed, the respective counters after mounting are not changed. An appropriate initial value can be set, and the degree of freedom in use is improved.
