Next, the operation of the ejection device will be explained with reference to the operation flow of the control circuit 45 shown in FIG. Pull out shelf 2... backwards, insert it, and store it in its original position.

Note that since the release position of the cylindrical coins 3 is at the front of the coin storage section 1, it is possible to replenish the empty storage shelf 2 with the cylindrical coins 3 when the cylindrical coins 3 are discharged.

The cylindrical coins 3 for normal exchange are discharged from the lowermost storage shelf 2.

At the start of operation after storing the cylindrical coins 3 in each storage shelf 2..., the lowest storage shelf 2 is in a retracted state, and the dog unit 17 is at the lowest position detected by the fourth switch 57. Waiting in position.

Alternatively, the dog unit 17 may be raised by one step to make the lowest storage shelf 2 protrude and stand by.

When a customer's money exchange operation (or a money exchange command) is input, the number of cylindrical coins 3 to be exchanged is preset in the counter 55.

When the forward rotation finger ♦ is input to the first motor drive circuit 47, this circuit 47 drives the first motor 46 in the forward rotation, thereby rotating the first chain 20.

This rotation causes the dog unit 17 to rise, and the first dog 21 comes into contact with the operation part 16 of the stopper lever 11 of the lowest storage shelf 2 and pushes it up, causing the first locking piece 7 of the storage shelf 2 to
and the rear end 12 of the stopper lever 11,
The storage shelf 2 projects to the extraction position due to its own weight, and the second locking piece 8 engages with the stopper piece 13 to maintain that position.

When the first dog 21 described above finishes the operation of protruding the storage shelf 2, the position detection switch 44 detects this, a stop command is input to the first motor drive circuit 47, and the first motor 46 is stopped.

Next, a forward rotation command is input to the second motor 1 drive circuit 49t, and this circuit 49 drives the second motor 48 in intermittent forward rotation.
The second chain 39 rotates intermittently so that the side facing the coin storage section 1 faces upward.

The take-out hanger 38 fixed to the chain 39 mentioned above extracts the cylindrical coin 3 upward from between the support rods 6, 6 of the storage shelf 2 at the lowest stage and transfers it upward. When the coins are removed from the storage shelf 2, this storage shelf 2 stores the subsequent cylindrical coins 3.
rolls to the 6°6 side of the front support rod under its own weight.

The cylindrical coin 3 taken out by the take-out hanger 38 is ejected from the chute 42. At this time, the ejection detection switch 56 detects the ejection of the cylindrical coin 3 and outputs a signal. Based on this detection signal, the counter 55 is activated. Subtracted.

When the count value of the counter 55 reaches zero and a discharge completion signal is output, a stop command is input to the second motor drive circuit 49 based on this signal, the second motor 48 is stopped, and the cylinder The dispensing of coin 3 is completed.

The ejection of the cylindrical coins 3 as described above is carried out every time money is exchanged, and when the cylindrical coins 3 on the lowest storage shelf 2 run out, the next upper storage shelf 2 is projected to the extraction position.

That is, the coin detector 35 is provided so as to detect the cylindrical coin 3 supported at the tip of the support rod 6 of the storage shelf 2 (the cylindrical coin 3 supported on the take-out hanger 33).
(not detected).

Therefore, when the last cylindrical coin 3 stored in the lowest storage shelf 2 is removed, the coin detector 35 detects the cylindrical coin 3.
Outputs a signal indicating that it is no longer available.

Based on this signal, a forward rotation command is input to the first motor drive circuit 47, the first motor 46 rotates forward, and the first chain 20 is driven.

Therefore, the dog unit 17 moves upward and the first dog 21
Operation part 1 of the stopper lever 11 of the next storage shelf 2
6 is pushed up to release the first locking piece 7 from the rear end 12 of the stopper lever 11, and the storage shelf 2 is projected to the extraction position.

When this operation is completed, a signal is output from the dog position detection switch 44, and based on this signal, a stop command is input to the first motor drive circuit 47, and the first motor 4
6 is stopped, and the upward movement of the dog unit 17 is also stopped.

This kind of protruding operation of the storage shelves 2 causes the cylindrical coins 3 in each shelf 2 to
As the number disappears, the steps are performed sequentially toward the upper stage.

Also, by moving the dog unit 17 upward, the second
The dog 25 comes into contact with the support rods 6, 6 of the empty storage shelf 2 and is pushed into the standby position by its upper edge 26.

The first locking piece 7 of the pushed-in storage shelf 2 is locked with the rear end 12 of the stopper lever 11, and the storage shelf 2 is stopped at the standby position.

The protrusion operation of each storage shelf 2 is performed sequentially, and the two from the top shelf are
When the storage shelf 2 of the third stage is projected to the extraction position, the plate 18 of the dog unit 1γ turns on the first switch 32.

Based on the signal from the first switch 32, a drive command is input to the forecast alarm drive circuit 50, and the forecast lamp or buzzer 51 is operated. Replenishment of 3 coins.

This plum payment is performed by exchanging an empty storage shelf 2 with a storage shelf preloaded with cylindrical coins.

Further, when the coin detector 35 detects that the cylindrical coin 3 stored in the second storage shelf 2 from the top is gone, the FF 54 is set, and the FF 54 outputs a command to search for supply coins. Ru.

Based on this search command, a normal rotation command is input to the first motor drive circuit 47, the first motor 46 rotates in the normal direction, the dog unit 17 is once moved to the upper end, and the second stage and the lower stage mentioned above are moved to the upper end. The storage shelf 2 is retracted to the standby position by the second dog 25.

Note that the first step is to move the dog unit 17 to the upper end.
The uppermost storage shelf 2 is once projected to the extraction position by the dog 21, but is also retracted to the standby position by the second dog 25.

When the dog unit 17 reaches the upper end, the second switch 3
3 detects this, and based on this detection signal, a reverse rotation command is input to the first motor drive circuit 4γ, and the first motor 46
is reversed, and the dog unit 17 is continuously moved to the lowest end.

At this time, the first dog 21 comes into contact with the operating portion 16 of the stopper lever 11, but the first dog 21 rotates upward to avoid it, and is returned to its original position by the spring 24.

When the dog unit 17 is further moved to the lower end, the fourth switch 57 detects this, and based on this detection signal, a normal rotation command is input again to the first motor drive circuit 47, and the first motor 46 is rotated in the normal direction. The dog unit 17 moves upward.

This upward movement is controlled to be stopped one by one from the lower to the upper tier of the storage shelf 2 by the dog position detection switch 44, and the supply of cylindrical coins 3 is checked by the coin detector 35 one by one.

The above-mentioned coin detector 35 (Thus, when the supply of cylindrical coins 3 is detected, the above-mentioned FF 54 # is reset by inputting the reset signal, stopping the search for supply coins, and detecting the supply of cylindrical coins 3. The cylindrical coin 3 is taken out from the stored storage shelf 2.

The uppermost storage shelf 2 (the stored cylindrical coins 3 are placed there as a spare).

When the search for supply coins is performed up to the second storage shelf 2 from the top and no supply coins are detected, the top storage shelf 2 placed as a reserve is projected to the extraction position by the dog unit 17. , the cylindrical coin 3 is taken out from the storage shelf 2.

The above-mentioned FF 54 is reset when the uppermost storage shelf 2 protrudes and the coin detector 35 detects the cylindrical coin 3 on this shelf 2.

When the above-mentioned dog unit 17 causes the uppermost storage shelf 2 to protrude, this protrusion occurs when the first switch 32 is turned on and the uppermost storage shelf 2 in one set of three stages of the dog position detection switch 44 is turned on.
is detected by the detection signal.

When the third switch 34 detects that the number of cylindrical coins 3 stored in the uppermost storage shelf 2 is running low, a drive command is input to the remaining alarm drive circuit 52, and the remaining lamp or buzzer 53 is activated. When activated, a warning is given that the storage amount of the cylindrical coins 3 is low, and the clerk replenishes the cylindrical coins 3 in response to this warning.

A reset signal for the forecast and low remaining alarm drive circuits 50, 52 is inputted by a switch (not shown) operated by an attendant at the time of replenishing the cylindrical coins 3, and the operation of the lamps or buzzers 51, 53 is stopped.
