DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a coin processing device incorporated in an automatic vending machine or the like for sorting and storing inserted coins.

(Prior Art) Conventionally, a coin processing device of this type has a coin sorting device on an upper side and a coin storage tube vertically installed on a lower side, and the coins sorted by denomination by the sorting device. Is provided with a plurality of coin passages that lead to the corresponding storage cylinders. Further, when paying out the change, the change-back mechanism arranged below the storage cylinder is activated, and the coin is controlled to be paid out from the storage cylinder according to the change amount. Furthermore, if the amount of coins paid out as change is large,
An overflow mechanism provided for each storage cylinder works to guide coins inserted thereafter to the safe through the safe passage.

FIG. 2 is a sectional view showing the above-mentioned overflow mechanism. In the figure, 201 is a coin passage and 204 is a distribution piece. The distribution piece 204 is located above the storage cylinder 202 and in the coin passage 201.
It is arranged between an opening 205 for receiving coins dropped from the outlet 201a and a coin passage 203, and is slidably supported by a shaft 206. When the storage cylinder 202 is not full of coins, the weight 207 attached to the lower end portion 204a of the sorting piece 204 causes the upper end portion 204b of the sorting piece 204 to open.
It abuts on a locking piece 208 provided on the edge of the coin passage 203 side of the 205. As a result, coins dropped from the coin passage 201 pass through the opening 205 and are stored in the storage cylinder 202. Also, the storage cylinder
When the coins are fully stacked on 202, the coins come into contact with the lower end portion 204a of the distribution piece 204 as shown by the chain double-dashed line. As a result, the distribution piece 204 rotates about the shaft 206 in the counterclockwise direction in the figure, and the upper end portion 204b of the distribution piece 204 opens from the storage tube 202 to the opening 2.
It contacts the side wall 202a reaching 05. Coin passage 201 to storage cylinder 2
The falling path to 02 is blocked by the distribution piece 204, and coins falling from the coin passage 201 are guided to the safe passage through the coin passage 203 along the slope formed by the distribution piece 204. ing.

(Problems to be solved by the invention) However, in the conventional coin processing device, dust and an adhesive substance enter together with the coin, and the rotation operation of the sorting piece 204 and the slip of the coin become slow, and the coin is jammed in the overflow mechanism. Occurs. For example, when a child throws in a coin with a sticky hand with a candy or the like, the coin is clogged. Therefore, there is a problem in that coins accumulate in the coin passage extending from the coin slot to the overflow mechanism and the function of the coin processing device is stopped.

In view of the above problems, an object of the present invention is to provide a coin processing device that does not stop its function even when a coin jam occurs in the overflow mechanism.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a selection means for detecting coins inserted from a coin insertion slot, determining the authenticity and denomination of the coins, and allocating the coins. A plurality of storage cylinders corresponding to the denominations of coins, a plurality of coin passages for guiding the coins determined to be true by the sorting means to the corresponding storage cylinders, and the false passages by the sorting means. A coin passage that guides the determined coin to the counterfeit coin chute that communicates with the return port, and a coin dropping path that is located above the storage cylinder and from the outlet of the coin passage to the storage cylinder. In a coin processing device having a plurality of overflow mechanisms that guide coins to a safe passage that communicates with the safe when the coin is full, a coin jam is detected in the vicinity of each outlet of the coin passage and the sorting means is detected. Outputs a clogging detection signal A coin detecting means is provided, and the sorting means is a coin for which the coin jam is detected when the insertion of a coin from the insertion slot is detected while the jam detecting signal is being output from the jam detecting means. Proposing a coin processing device characterized in that coins of a denomination corresponding to a passage are distributed to the false coin passage, and coins of a denomination corresponding to a coin passage in which the coin jam is not detected are distributed to the coin passage. To do.

(Operation) According to the present invention, when the coin is fully stored in the specific storage cylinder, the coin of the denomination corresponding to the storage cylinder is normally guided to the safe passage by the overflow mechanism. Also,
When coins are jammed in the overflow mechanism, the coins that are inserted subsequently accumulate in the overflow mechanism.When the coins reach the vicinity of the exit of the coin passage corresponding to the overflow mechanism due to the accumulation of coins. Then, the jam detection means detects the jam of coins. Furthermore, based on the detection result of the clogging detection means, when a coin of a denomination corresponding to the overflow mechanism in which the clogging of the clogging has occurred by the sorting means is inserted from the insertion port,
The coin is returned without being accepted. Further, if the coin inserted from the insertion slot is a coin other than the denomination corresponding to the overflow mechanism in which the jam occurs, the coin is accepted and stored in the storage cylinder through the coin passage or the safe through the safe passage. .

(Embodiment) FIG. 1 (a) is a simplified front view of a coin processing device according to an embodiment of the present invention, and FIG. 1 (b) is II of FIG. 1 (a).
It is a detailed sectional view of a line arrow direction. In the figure, reference numeral 1 denotes a coin sorting device, which is located below the sorting device 1 for storing coins A, B,
C, D, fake coin chute E and auxiliary storage cylinders F, G are arranged.

The sorting apparatus 1 has a hopper-shaped coin input port 2 on the upper side, and a chute 3 for the input coin passage, a coin inspection coil 4, and three sorting gates 5, 6, and 7 are installed inside the sorting device 1. Coin passages 3A, 3B, 3C, 3D, 3E are branched from the distribution gates 5, 6, 7 toward the respective storage cylinders A, B, C, D and the fake coin chute.

The coin inspection coil 4 magnetically detects the material, shape, and the like of the coins passing over the chute 3 to determine their authenticity and denomination. The sorting gates 5, 6, 7 switch the passages by solenoids 9, 10, 11 to transfer coins to the coin passages 3A, 3B, 3 according to the denomination.
Distribute to C, 3D, 3E.

The storage cylinders A, B, C, and D are elongated tube shapes with an inner diameter corresponding to the outer shape of coins of each denomination, and are arranged corresponding to the outlets of the coin passages 3A, 3B, 3C, and 3D, respectively. It stores Yen coins, 50 Yen coins, 100 Yen coins, and 500 Yen coins. The auxiliary storage cylinders F and G are
Coins for change are arranged side by side on both sides of the storage cylinders A, B, C.
Mainly 10 yen coins can be supplied manually. The counterfeit coin chute E has its upper end arranged corresponding to the exit of the counterfeit coin passage 3E and its lower end communicating with a coin return port (not shown).

Under the storage cylinders A, B, C, D and the auxiliary storage cylinders F, G, a known change return mechanism 13 is disposed, and in the storage cylinders A, B, C, D and the auxiliary storage cylinders F, G. Stacked coins can be sent as change from the bottom to the return port. Also, storage cylinders A, B,
Overflow mechanism 14A, 14B, 1 on top of each of C, D
4C and 14D are provided, and when coins are fully stacked in each storage cylinder, coins of the same denomination inserted later are inserted into the coin passages 3a, 3b,
It leads to the safe passage 15 through 3c and 3d.

The overflow mechanism 14C described above is configured by using the distribution piece 101 as shown in FIG. 1B, for example. The sorting piece 101 is disposed above the storage cylinder C and between the coin passage 3c and the opening 103 for receiving the coin dropped from the outlet 102 of the coin passage 3C, and is swingably supported by the shaft 104. ing. When the storage cylinder C is not full of coins, the weight 105 attached to the lower end 101a of the sorting piece 101 causes the upper end 101b of the sorting piece 101 to move toward the coin passage 3c side of the opening 103. Coins that have come into contact with the locking piece 106 on the edge and have fallen from the coin passage 3C are stored in the storage cylinder C through the opening 103.
Also, when coins are fully stacked in the storage cylinder C, the sorting piece 10
When a coin comes into contact with the lower end portion 101a of 1, the sorting piece 101 rotates counterclockwise about the shaft 104, and the upper end portion 101b of the sorting piece 101 reaches the side wall 107 from the storage cylinder C to the opening 103. Is held in contact with. As a result, the coins subsequently sent to the storage cylinder C are guided to the coin passage 3c along the slope formed by the sorting piece 101. Other overflow mechanisms 14
A, 14B, and 14D have the same structure.

Also, at the exits of the coin passages 3A, 3B, 3C, 3D,
For example, a jam detection sensor 16A, 16B, 16C, 16D using a coin detection device disclosed in Japanese Patent Application Publication No. 58-501344.
Is installed. These clogging detection sensors 16A, 16
When B, 16C and 16D are clogged with coins at the respective outlets of the coin passages 3A, 3B, 3C and 3D, the coins are detected and a clogging detection signal is sent to the sorting device 1. The sorting device 1 is a clogging detection sensor 16A, 16
While receiving a jam detection signal from any of B, 16C, and 16D, if a coin of the denomination corresponding to the coin passage where the coin is jammed is inserted, this coin is distributed to the false passage 3E. , Through the fake coin shoot E, and is led to the return port.

The coin processing device having the above-described configuration operates as follows.

The coin inserted from the coin insertion slot 2 is discriminated between its authenticity and denomination by the coin inspection coil 4 while passing through the chute 3 and depending on the signal from the coin inspection coil 4. The distribution gates 5, 6 and 7 operate in the mode shown in FIG. In FIG. 3, “∘” indicates the solenoid on state, and “x” indicates the solenoid off state. The gate is designed to open when the solenoid is on. Further, the solenoid that has been turned on returns to the off state in a short time. That is, when counterfeit coins are thrown in, all gates are closed, so they fall through the counterfeit coin passage 3E and counterfeit coin chute to the coin return port. When a 500-yen coin is thrown in, the sorting gate 5 is opened and coins fall into the storage cylinder D through the coin passage 3D. When a 100-yen coin is thrown in, the sorting gates 5 and 7 are opened, and coins fall into the storage cylinder C through the coin passage 3C. When a 50-yen coin is thrown in, the sorting gates 5 and 6 are opened, and the coin drops into the storage cylinder B through the coin passage 3B. When a 10-yen coin is thrown in, the sorting gates 5, 6, 7 are opened, and coins fall into the storage cylinder A through the coin passage 3A.

Further, one of the jam detection sensors 16A, 16B, 16C, 16D detects a jam of coins, and the jam detection signal is sent to the sorting device 1
When coins of the denomination corresponding to this coin jam are inserted while outputting to, the sorting gate 5 is closed and the coins are sent to the return port through the false coin passage 3E and the false coin chute E. Sent. For example, if a 100-yen coin thrown in by a child with a sticky hand is slippery and sticks to the sorting piece 101 of the overflow mechanism 14C as shown in FIG. 1 (b), The 100-yen coins that are thrown in later are accumulated in the overflow mechanism 14C. When the coins are accumulated up to the outlet 102 of the coin passage 3C, the jam detection sensor 16C detects the jam of coins in the overflow mechanism 14C. Furthermore, based on the jam detection signal of the jam detection sensor 16C, the sorting device 1 closes the sorting gate 5 and closes the fake coin passage 3E and the fake coin when a 100-yen coin is thrown in while the coin jam is detected. This 100-yen coin is sent to the return port through the currency passage 3E and the fake coin shoot E.
The same operation is performed when the other jam detection sensors 16A, 16B, 16D detect the jam of coins. As a result, even if a coin jam occurs in the overflow mechanism 14A, 14B, 14C, 14D, a large amount of coins will not be accumulated in the coin passages 3A, 3B, 3C, 3D, and the function of the coin processing device will stop. There is no.

In addition, if the coin processing device of the present invention is incorporated into a vending machine for products, even if a coin jam occurs in the overflow mechanism 14A, 14B, 14C, 14D, a denomination other than the denomination causing the coin jam will be generated. Since it is possible to sell products with coins, there is no chance of losing product sales.

In this embodiment, the clogging detection sensors 16A, 16B, 16C, 16
Although the magnetic sensor described above is used for D, the present invention is not limited to this. For example, the same effect can be obtained by using an optical sensor including a phototransistor and an LED.

(Effect of the Invention) As described above, according to the present invention, when a coin jam occurs in the overflow mechanism due to dust or an adhesive substance entering with the coin, this is detected by the jam detecting means, Based on the detection result, when a coin of a denomination corresponding to the overflow mechanism where the clogging of the clogging has occurred by the sorting means is thrown from the slot, the coin is not accepted and returned Coins will not accumulate in the coin passage from the mouth to the storage cylinder. In addition, if the coin inserted from the slot is a coin of a type other than the denomination corresponding to the overflow mechanism in which the clogging has occurred, the coin is accepted,
Since the coin is stored in the storage cylinder through the coin passage or the safe through the safe passage, it is possible to prevent the coin processing device from stopping its function.

Furthermore, if the coin handling device of the present invention is incorporated into a vending machine for goods, even if a coin jam occurs in any of the overflow mechanisms 14A, 14B, 14C, 14D, it can handle the overflow mechanism causing the coin jam. Since it is possible to sell products with coins of denominations other than the denomination, it is possible to prevent loss of product sales opportunities.
