Description

Description: [Industrial field of application] The present invention relates to a coin sorting device for use in vending machines, currency exchange machines, and service equipment.

[Conventional technology]

Generally, a coin sorting device has a complicated coin passage for sorting coins inserted into the device main body into genuine coins and counterfeit coins, and sorting coins regarded as genuine coins by denomination. A coin discriminating device including, for example, an oscillating coil and a receiving coil in a part of the coin passage formed in such a complicated manner,
And, a sorting device such as a plurality of solenoids for allocating coins to a predetermined coin passage is arranged, and while the inserted coin passes through the predetermined coin passage while tumbling and passing, sorting of genuine and false coins and denomination of coins The distribution is performed so that the fake coins are guided to the predetermined coin passages and the true coins are guided to the predetermined coin passages formed by the denominations.

[Problems to be Solved by the Invention]

By the way, as described above, in the coin sorting device, a complicated coin passage is formed in the main body of the device, and since the coin rolls in this coin passage, for example, a soft drink, a detergent, etc. When the liquid is poured, the liquid also flows into the main body of the apparatus along the coin passage. When such a sticky liquid such as detergent flows in the coin passage, the liquid adheres to a sorting device such as a solenoid arranged in the coin passage, causing the operation to be defective and the sorting function to deteriorate. Was invited. In addition, when the sticky liquid attached to these sorters dries, it may lock the operation of these sorters, which not only stops the function of the coin sorter itself, but also extends to the coin tube side. There is also a problem that the liquid flows in and electric parts such as an electronic circuit and a motor are short-circuited to cause malfunction.

In view of the above circumstances, an object of the present invention is to provide a coin sorting device in which liquid introduced through a coin inlet is prevented from adhering to a sorting device or the like arranged in the main body of the device.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, in the present invention, a liquid guide groove having a weir is formed on a wall surface of a coin passage that directly communicates with a coin slot along a substantially vertical lower side of the coin slot, and the coin is provided. A collection unit for liquid that drops along the guide groove is provided below the passage, and a discharge passage that communicates with the collection unit and discharges the liquid collected in the collection unit to the outside of the coin sorting device. I am trying to set it up.

[Action]

According to such a coin sorting device, the liquid poured from the coin input port is guided by a weir that controls the flow of the liquid without entering the complicated sorting coin passage formed in the coin sorting device. The coins are discharged to the outside of the coin sorting device through the groove, the collecting unit, and the discharge passage.

Incidentally, reference numeral 30 in FIG. 8 is a fitting for the tube 21.

〔The invention's effect〕

As described above, in the coin sorting device of the present invention, the side wall of the coin passage that directly communicates with the coin slot is provided with the guide groove for guiding the liquid charged from the coin slot downward in the substantially vertical direction. Since the liquid that has fallen down the guide groove is collected and discharged to the outside of the main body of the device, even if a sticky liquid such as detergent is poured from the coin insertion slot, the liquid will remain inside the main body of the device. Therefore, it is possible to provide a coin sorting device having a stable sorting function, because it does not flow into the passage and does not adhere to various sorting devices arranged in the coin sorting device. Also,
It is possible to effectively protect the coin sorting device against a malicious mischief that pours liquid such as detergent, prevent its function from deteriorating, and prevent damage to the mischief.

In addition, since a weir is installed in the guide groove to control the flow of liquid, the liquid introduced from the coin input port is not abruptly guided to the collection unit, and therefore a large amount of liquid is poured from the coin input port. However, the collecting unit does not overflow and the liquid does not adhere to the coin passage or the like in the coin sorting device.
