Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is used in coin mechanisms used in vending machines, etc., to replenish coins into the change storage cylinder especially when the change storage cylinder is short of coins. The present invention relates to a coin collecting device with a coin mechanism equipped with a replenishing device.

(b) Prior Art Such a coin mechanism is disclosed in Japanese Patent Application Laid-open No. 50-66298, and the configuration of this type of device will be explained with reference to FIG. 1. After the coins inserted through the coin input port 7 are sorted by a sorting section 8, proper coins are introduced into the change storage cylinder 1, and non-proper coins are introduced into a return passage 9. The coins in the change storage tube 1 are dispensed as change by the change dispensing device 2, and the change dispensing device 2 is driven to dispense coins even when coins are collected. Incidentally, the supply tube 10 of the supply device 4 is prepared with coins of a type frequently used as change, and when the number of coins stored in the change storage tube 1 is less than a predetermined number and the change is insufficient, the change detection device 3 is used. When detected, the replenishing device 4 is driven to replenish coins into the change storage tube 1 via the replenishing passage 11. If the amount of coins stored in the change storage tube 1 does not recover to the predetermined number or more even if the replenishment device 4 is driven, the replenishment tube 10 will also be out of coins and the replenishment device 4 will stop operating thereafter.

When collecting coins with the above configuration, when the collection switch 5 is operated to drive the change dispensing device 2, the coins in the change storage tube 1 are collected, and each time the number of stored coins is less than a predetermined number, the coins are moved to the replenishment tube 1 as appropriate. Since the coins inside are introduced into the change storage tube 1, all the coins held in the change storage tube 1 and the supply tube 10 are collected by the change dispensing device 2.

However, in the above collection operation, if the change dispensing speed of the change dispensing device 2 is faster than the coin replenishing speed of the replenishing device 4, the supply of coins cannot keep up and the number of coins stored in the change storage cylinder 1 gradually decreases. This results in a situation where the replenishment operation does not recover the number of sheets beyond the predetermined number. In this case, the replenishment device 4 ends its operation even if there are coins left in the replenishment tube 10, and it becomes impossible to collect all the coins from the replenishment tube 10 and the change storage tube 1. Therefore, if the coin replenishment speed is set faster than the change dispensing speed, the replenishment speed will become extremely fast and there is a risk that the replenishment passage 13 will become clogged. Furthermore, even if a separate circuit is used to continue the replenishment operation regardless of the state of the change detection switch 3 only when collecting coins, if the change dispensing speed is even slightly faster, the amount of change in the change storage cylinder 1 will decrease despite replenishment. A situation may arise in which the coins eventually run out and remain only in the supply cylinder 10. In this case, the coins introduced from the replenishing device 4 are immediately dispensed from the change dispensing device 2, but if the timing of introduction and the operation timing of the change dispensing device 2 do not match, the coins are withdrawn by the change dispensing device 2. There is a risk of getting stuck.

Therefore, it is desirable to make the change dispensing speed and the replenishment speed completely match, but this requires complicated control due to the structural differences between the two. Therefore, Japanese Utility Model Application Publication No. 55-169771 discloses a configuration in which the change dispensing speed is lower than the normal dispensing speed and slower than the replenishment speed only when collecting coins, thereby leaving coins in the replenishing cylinder 10. It can be collected without any problems, and clogging during collection can be prevented.

(c) Problems to be solved by the invention However, the above method has the drawback that the coin dispensing speed at the time of collection is slow, so that the collection operation takes time.

The present invention was developed in view of the above points, and by switching the coin dispensing speed to a low speed only when there are few coins left in the change storage tube during collection, the change storage tube of the replenishing device and coin mechanism can be stored. To provide a device that can reliably collect coins in a short time.

(d) Means for Solving the Problems In order to solve the above problems, the coin collecting device for a vending machine according to the present invention includes a change storage cylinder, a change dispensing device that dispenses coins from the change storage cylinder. a change detection switch that detects when the change coins in the change storage cylinder are out of change based on a predetermined number of coins; a replenishing device that introduces a specified number of coins into the change storage cylinder when the change coins run out; a collection switch that drives the change dispensing device; a first power source that energizes the replenishment device and the change dispensing device; and a second power source that energizes the change dispensing device for low-speed driving.
a first switching device that connects the change dispensing device to the first power source and switches from a first switching mode to a second switching mode in response to an operation of the collection switch; A first switching mode in which the first switching device is connected to the change dispensing device when the first switching device is in the second switching mode, and connects the change dispensing device to the first power source in response to detection of out of change by the change dispensing device. and a second switching device that switches from the change dispensing device to a second switching mode that connects the change dispensing device to the second power source.

(e) Effect When the recovery operation is activated by operating the recovery switch,
The first switching device switches to the second switching mode. At this time, if there are more than a predetermined number of coins in the change storage tube,
Since the second switching device connects the change dispensing device to the first power source, the change dispensing device dispenses coins from the change storage cylinder at a normal dispensing speed. Then, when the number of coins stored in the change storage tube becomes low and the change detection switch is activated and the replenishing device is powered by the first power source and driven to replenish the change into the change storage tube, the change dispensing device is activated. , for the second switching device to switch to the second switching mode and be connected to the second power source;
Switched to slow payout. However, when the change dispensing speed decreases and the number of coins stored in the change storage cylinder exceeds the specified number due to replenishment, the change detection switch becomes inoperable and the second switching device switches to the first switching mode, and normal dispensing is resumed. Coins are collected at speed.

(F) Embodiment An embodiment of the present invention will be explained with reference to Fig. _2.L1 is a common line, _L2 is a power supply for normal speed rotation,

Ry ₃ is a replenishment control relay connected between L ₁ and L ₂ through relay contacts R _2-1 and R _3-2 .
CS ₁ and CS ₂ are cam switches associated with the drive motor M ₂ respectively, and the drive motor M ₂ is connected between L ₁ and L ₂ through the cam switch CS ₂ to form a self- _energizing circuit; Relay contact between ₂
R _2-1 , cam switch CS ₁ a contact, relay contact
Connected through R _3-1 to form a starting circuit. And relay Ry ₃ has a relay contact between L ₁ and L ₂
R _2-1 and cam switch CS ₁ b contact and relay contact
Connected through a parallel circuit of R _3-2 . The drive motor _M1 is connected to a change dispensing switch 12 which is closed in response to a predetermined change dispensing command and a parallel circuit 13 of a relay contact _R1-1 , and is connected to a parallel circuit 13 of a relay contact _R1-2 which is a first switching device. Relay contact R _1-2
B contact/second switching device, relay contact R _2-2
is connected between L ₁ and L ₂ through the a contact of
Between L ₁ and L ₂ , parallel circuit 13 / relay contact R _1-2
Connected through the b contact of relay contact R _2-2 . In this way, when the relay contact R _1-2 , which is the first switching device, switches to the a contact, it becomes the first switching mode that connects the drive motor M ₁ of the change dispensing device to the power source L ₂ , and when it switches to the b contact, it becomes the first switching mode. drive motor
The second switching mode connects M ₁ to relay contact R _2-2 . Also, the relay contact which is the second switching device
When R _2-2 switches to the A contact, it becomes the first switching mode that connects the drive motor M ₁ to the power supply L ₂ , and when it switches to the B contact, it becomes the second switching mode that connects the drive motor M ₁ to the power supply L ₃ . becomes.

First, the normal change dispensing operation in the above configuration will be explained. In this case, when the change dispensing switch 12 is closed for a predetermined change dispensing period in response to the change dispensing command, the relay contact R _1-2 is closed to the a contact, and the drive motor M ₁ is switched to L ₁ , L ₂ connected to
The change dispensing device 2 dispenses change at a normal dispensing speed. However, during the change dispensing period of the lever, the change storage cylinder 1
When the number of coins stored in the coins is less than the predetermined number and the change is out, the change detection switch 3 closes, the relay is activated.
Since Ry ₂ is excited and relay contact R _2-1 is closed, drive motor M ₂ is connected to L ₁ and L ₂ through the a contact of cam switch CS ₁ and relay contact R _3-1 , and replenishment device 4 starts replenishment operation. Start. and drive motor
When M ₂ is driven, cam switch CS ₂ is closed for a certain period of time to form a self-energizing circuit, and cam switch CS ₁ is also driven by drive motor M ₂ to close contact b, so relay Ry ₃ is energized and the contact is closed. Self-maintaining due to R _3-2 . Thereafter, when the drive motor _M2 is driven for a predetermined period of time and a specified number of coins are replenished into the change storage tube 1, the cam switch _CS2 is opened and the replenishment operation is completed. Due to this replenishment operation, the change storage tube 1
When the number of stored change exceeds a predetermined number and change detection switch 3 is opened, relay Ry ₂ is demagnetized, so relay Ry ₃ is also demagnetized, and when the number of stored change is less than a predetermined number, the same operation is started again. However, when the supply device 4 runs out of coins, although the drive motor _M2 is driven, the change storage tube 1 does not recover to the predetermined number of coins, the change detection switch 3 remains closed, and the relay Ry ₃ is continuously energized. . Therefore, in this case, since the relay contact R _3-1 is opened, a self-energizing circuit for the drive motor M ₂ is not formed, and no replenishment operation is performed thereafter.

Next, the collection operation will be explained. When the recovery switch 5 is operated, the relay Ry ₁ is connected between the lines L ₁ and L ₂ and energized, and the drive motor M ₁ connects the relay contact R _1-1 , the b contact of the relay contact R _1-2 , and the relay contact R _2. The change dispensing device 2 is connected to and driven between L ₁ and L ₂ through the a contact of _-2 , and the change dispensing device 2 dispenses coins from the change storage cylinder 1 at a normal change dispensing speed. Then, when the number of stored coins falls below a predetermined number, the relay Ry ₂ is energized in the same manner as described above, so that the change storage tube 1 is replenished with coins from the replenishment device 4. However, during this replenishment, the relay contact R _2-2 of the drive motor M ₁ is switched to the B contact due to the excitation of the relay Ry 2 and is connected to L ₃ , so _the change dispensing device 2 dispenses coins at a low speed. However, when the number of stored coins reaches a predetermined number or more due to replenishment and the relay Ry ₂ is demagnetized, the relay contact R _2-2 returns to the a contact, so that coins are dispensed at the normal speed again. If all the coins in the supply device 4 are introduced into the change storage tube 1, and the number of coins stored is less than the predetermined number,
The change dispensing device 2 dispenses the remaining coins at a low speed,
At the end of dispensing, the collection switch 5 is reset and the relay is activated.
Demagnetize Ry ₁ and complete the collection operation.

(g) Effect of the device According to the device detailed above, the collection switch can be
When the out-of-change switch detects that change is out while it is turned on, the coin dispensing speed of the change dispensing device is switched to a speed lower than the normal speed, so that all the coins in the replenishing device can be collected. Also, since the payout is performed at a low speed only when the number of coins stored in the change storage cylinder is less than a predetermined number, the collection time is almost the same compared to collecting all coins at the normal payout speed. remains unchanged. Moreover, when the replenishing device operates, the change dispensing speed is lower than the replenishing speed, so that stable collection processing is performed without causing coins to become jammed in the device.
