Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for coin dispensing in a coin sorting and dispensing machine.

The coin sorting and dispensing machine is a device that sorts and stores coins of many denominations by denomination, and dispenses only the required amount based on a dispensing counter from a dispensing command unit (not shown). be.

In the above-mentioned sorting and dispensing machine, the amount of stored coins required for dispensing must be secured. If the dispensing operation was enabled or disabled depending on the presence or absence of coins in the storage cylinder as in the past, when the amount of coins replenished was small, the operation would immediately become impossible again, making it impossible to perform continuous dispensing operations. It's inconvenient.

Therefore, an object of the present invention is to provide an effective control device for the dispensing operation.

The present invention will be specifically explained below.

First, the outline of the coin sorting and dispensing machine on which the present invention is based will be explained based on FIG.

The coin sorting and dispensing machine 1 includes a coin supply section 2, a coin sorting section 3, a coin storage section 4, and a coin dispensing section 5.

The coin supply unit 2 sequentially sends out coins □ of various denominations from the supply port side by centrifugal force caused by the rotation of the rotating disk 6.

Although not shown, the rotating disk 6 has a pair of electrodes as coin detection means on its coin storage surface, and is driven by a motor IT.
The pair of electrodes detects the presence of the coin 7 on the rotating disk 6 using the conductivity of the coin T. The coin sorting section 3 has the function of sorting the sent coins T of various denominations by denomination.

The coins □ are sequentially sent through a sorting passage 8 having a concave cross section by a group of feeding rollers 9. Here, the feed roller 9 is not perpendicular to the feed direction, and presses the coin T against one side of the sorting path 8 by the lateral force of its rotation. And sorting passage 8
has a sorting hole 101 on its bottom surface starting from one side,
102...105. These sorting holes 101, 102...10 become larger in the direction of coin □ feeding, and correspond to the coin diameters of 1 day, 50 yen, 5 yen, 100 yen, and 10 yen, respectively. are doing. The coin storage section 4 is located below the sorting passage 8 and stores sorted coins 7.

Therefore, the above-mentioned screening holes 101, 102...105
Storage cylinders 111, 112, . . . , 115 are erected for each. In addition, the storage tubes 111, 112...
In order to store coins that can no longer be stored in 115,
Gold boxes 121, 122, . . . , 125 are attached to each denomination. The coin dispensing section 5 includes each storage tube 111, 112.
. . . Based on a dispensing signal from a dispensing command section (not shown) located at the lower part of the cylinder 115, the required amount of coins 7 are dispensed from the cylinder.

Then, a guide switching plate 13 is placed in the falling path of the coins 7 of each denomination listed below.
1,132...135 are rotatably supported by a support shaft or the like.

These guide switching plates 131, 132...135
are each operated by an electromagnetic plunger or the like. Moreover, each of the storage cylinders 11. , 112...11, are overflow detection means 141, 142...145 for detecting the maximum stacked amount of coins 7, and coin sufficiency detection means 151, 152... to be described later. ...155 and coin shortage detection means 161, 162, which will be described later...16. A
- have.

These means include, for example, a pair of electrodes provided at the bottom of the storage cylinder and at each detection position. In that case, when the coin 7 contacts the upper electrode, the electrode (not shown) at the bottom of the storage cylinder is electrically closed through the upper electrode and the stacked coins 7, so a predetermined signal is generated between these pair of electrodes. do. Of course, these detection means may be constituted by optical means using a light emitting element and a photoelectric element, or mechanical means using a micro switch. Now, when coins 7 of various denominations are inserted into the rotating disk 6, the coin detection means (not shown) detects the coins and starts the motor 17, and as a result, the rotating disk 6
rotates, and the coins 7 thereon are sequentially sent out from the supply port side to the sorting passage 8.

The coins 7 of various denominations in the sorting passage 8 are moved while being pressed against one side of the sorting passage 8 by the rotation of the feed roller 9. During the movement, the 1 yen coin 7 with the smallest diameter is placed in the sorting hole 1.
0t). Next, the other 50 yen, 5 yen, 100 yen and 10 yen coins 7 are sequentially placed in the corresponding sorting holes 10, 1.
Falling from 03...10. In this way, the coins 7 of various denominations are sorted sequentially, and each storage tube 111,
112...11,. Here, the guide switching plates 131, 132...13,
When the coins in the storage tube 11 are not piled up to the position of the overflow detection means 14, they fall to the left, so the classified coins 7 are stored in each storage tube 111, 112, etc.
・You will be inside 115. For example, when the storage cylinder 111 is detected by the overflow detection means 141 and the electromagnetic plunger at that position is activated, the guide switching plate 13
1 rotates clockwise, then the coin 7 is placed in the money box 1.
Enter 21. Next, the dispensing control device 21 of the present invention will be specifically explained.

The dispensing control device 21 includes the previously described coin sufficiency detection means 151,
152...155 Coin shortage detection means 161,1
62...165, and storage control circuits 221, 222...225, lock means 29, and alarm means 28 are added to these.

The functions of each of the above parts are as follows.

The coin shortage detection means 16, 162...165 are connected to the storage tubes 111, 112...11, respectively.
When it is detected that the number of stored coins 7 in 5 has become less than the maximum number of coins to be dispensed at one time, a coin shortage signal S1 is generated. The coin sufficiency detection means 151, 152...155,
The storage tubes 111, 112, . . . generate a coin sufficiency signal S2 when the eleventh stored coin 7 is at the maximum number of coins that can be dispensed several times or more. Locking means 29
functions to stop the operation of the coin sorting and dispensing machine 1 upon receiving the insufficient coin signal S1. Further, the alarm means 28 is
A display element is provided corresponding to each of the storage cylinders to issue a light or sound alarm when the coin shortage signal S1 is generated and to display which storage cylinder is short of coins. And memory control circuit for each denomination ・221222...
225 is a pair of NAND circuits 231, 241, 242, 23 as flip-flop circuits.
It is composed of 5, 24,. Memory control circuits 221, 22
2...225 is set to the initialization reset state by the signal S3 of the initialization circuit 30, and is frozen by the coin shortage signal S1, and is set by the coin sufficiency signal S.
It is reset at 2. Note that the memory control circuits 221 and 222
...Inverter circuit 251 on the Q output side of 225
, 252...255 and display lamps 261, 2
62...26, are attached. The Q outputs of all the memory control circuits 221, 222, .
to go into. Next, the operation will be explained.

When the power is turned on, an initialization reset is applied, and a low level or "L" signal is output to the NAND circuits 231, 232, . . . 235 of the memory control circuits 22, 222, . enters. The coin shortage signal S, is the third
As shown in the figure, the weight of the stored coins T is determined by the coin shortage detection means 16.
When it becomes less than 1,162...165, it outputs an "L" signal, and at other times it outputs a high level, that is, an "H" signal. The coin sufficiency signal S2 indicates, as shown in FIG.
...When it is lower than the position of 155, it outputs an "H" signal, and at other times it outputs an "L" signal. When the initialization reset signal S3 and the ``-q-L'' signal enter the NAND circuits 231, 232, . The Q output of the storage control circuit 22k(1), where S2 is the "..." signal, becomes the "L" signal.

This "L" signal is converted into an "H" signal by the inverter circuit 25k, and lights up the lamp 26k. Also, if even one Q output is an “L” signal, the output of the NAND circuit 21 will be “H”.
” becomes a signal. Due to the presence of this "H" signal, the alarm means 28 and head knock means 29 are activated and an alarm is issued,
And the subsequent throwing operation force is detected. In other words, when the power is turned on, if the accumulated coins T are below the coin sufficiency detection means 15k or are absent,
Only the lamp 26k of the denomination in that state is lit, and at the same time the alarm means 28 and the lock means 29 are activated.
And then coins? The denominations are sorted and placed in the storage tubes 11, 112, . . . , 115 for each denomination.

When the stacked amount of stored coins T for all denominations exceeds the position of the coin sufficiency detection means 151, 152...155, all the storage control circuits 221, 222...
- The Q output of 225 becomes an "H" signal. Therefore, all the lamps 261, 262, .
Therefore, ejection activation is possible from this point on. At this time, the coin shortage signal S1 is an "H" signal, and the coin sufficient signal S1 is an "H" signal.
2 is an "L" signal. By the way, suppose that the dispensing operation is repeated and only the stored coins T, for example, 1 yen, have decreased.

A 1 yen coin? Even if the coin sufficiency signal S2 becomes an "H" signal, the output of the NAND circuit 231 is an "L" signal, so
The Q output of the storage control circuit 22 is also an "H" signal.

However, when the number of coins T decreases further and becomes slightly below the position of the coin shortage detection means 16, the coin shortage signal S,
It becomes an "L" signal. In this way, both of the two input signals of the NAND circuit 24 become "H" signals, so the lamp 261
lights up, and both the lock means 29 and the alarm means 28 are activated. The operator is informed of the shortage of 1 yen coins T by the alarm. Further, the coin dispensing section 5 is locked in a dispensing inoperable state. It should be noted that while the -cycle dispensing operation is in operation, the head knocking means 29 is prevented from being locked by a known means (not shown) before it is completed. After that, when the 1 yen coin 7 is supplied to the storage tube 111 and the coin shortage signal S1 becomes an "H" signal,
The coin sufficiency signal S2 is also an "H" signal. By this time, the "L" signal of the Q output has entered the NAND circuit 23,
The Q output becomes an "L" signal and is stable. Even if the coin shortage signal 'S' becomes an "H" signal, the NAND circuit 23,
The output of is unchanged and remains an "H" signal. Therefore, since the Q output of the storage control circuit 221 is at the level of the "L" signal, the lamp 261 and the locking means 29
and the alarm means 28 are all in the on state. When 1 yen coins T are further replenished into the storage cylinder 111 and stacked higher than the coin sufficiency detection means 15, a coin sufficiency signal S is sent.
2 is the level of the "L" signal.

Then, the Q output becomes an "H" signal and the lamp 26
1. The lock means 29 and the alarm means 28 are all turned off. Therefore, from this point on, the re-throwing operation becomes possible. It is assumed that the coin supply operation is performed independently of the operation of the dispensing mechanism. The present invention has the following effects.

Once the coin shortage detection means detects a coin shortage, unless coins are piled up to the height of the coin sufficiency detection means,
Coins are not dispensed, and therefore continuous dispensing is possible to some extent. In the conventional system, the dispensing mechanism was inactivated only by the absence of coins. In other words, the present invention allows the dispensing mechanism to perform continuous dispensing to some extent, thereby contributing to a reduction in the frequency of on/off control and an increase in the number of consecutive dispensing operations. In addition, if there is a shortage of coins inside the storage tube, the dispenser will be immediately locked unless the -cycle dispensing operation is in progress, making it easy to prevent erroneous dispensing and confirm the missing coin type.
