Description

[Detailed Description of the Invention] The present invention relates to a coin sorting device, and is particularly effective in a coin sorting device that electronically or electromagnetically discriminates coins from a coin slot.

In other words, the coin sensor detects the presence or absence of an inserted coin between the coin input slot and the coin discrimination unit that determines the authenticity of the coin (genuine coin or counterfeit coin). A vibrator is provided to control the transfer operation of moving coins, so that even if coins are continuously inserted into the coin input slot, the coins guided to the coin discriminating section will be divided into the first coin and the subsequent coins as in the conventional case. The structure is such that the coins do not roll together with subsequent coins, but are always guided one by one at a predetermined distance apart according to the insertion order, so no matter what insertion operation is performed, the coins are To provide an excellent coin sorting device in which the discrimination operation performed by a separate section does not cause erroneous discrimination, and the gate can also operate the coin sorting operation controlled by these coin discrimination sections. It is something.

In this respect, in conventional electronic or electromagnetic coin sorting devices, coins simply inserted through the coin slot are not subjected to any control and are rolled on the coin rail while being sorted by the coin discrimination section. Therefore, if coins are continuously inserted into the coin slot mentioned above, the coins will be guided in a band shape according to the order of insertion, so the reliability may be affected. Even if a coin is equipped with a high-quality coin recognition unit, the shape and size of the coin will be recognized by the coin recognition unit as a deformed pattern, so no matter how genuine the coin is, it is generally known as a counterfeit coin. There was a risk that this would lead to the undesirable result of being led to death.

Therefore, the present invention was developed in order to solve these problems.

Furthermore, another purpose of the present invention is that when the input coins are continuously guided to the coin discriminating section, the coin distribution is also guided to the gate in a similar manner, so that the gate is connected to the coin discriminating section. Even if the coins from the two rolling mills that cannot keep up with the discrimination operation are counterfeit coins, they should be taken into the genuine coin passage as genuine coins, or the coins that are separated by the two millstones should be caught at the gate. There was a risk that the decision to do so would lead to undesirable results.

In other words, since the first coin is a genuine coin, the gate will naturally open for distribution, but if the coins in the second mortar are counterfeit coins, the coin handler 1 will be able to prevent the counterfeit coins from leaving the coin discrimination section. At the same time, the currency is determined to be counterfeit and a blockage signal is output to the gate.

However, by this time, the counterfeit coins have already reached the top of the gate, so even if the gate is immediately blocked, the counterfeit coins will either be taken into the genuine currency passageway45 or the counterfeit coins will be caught at the gate. Therefore, for the manufacturers of these coin sorting devices, in anticipation of these defects, the coins input to the coin sorting unit have been continuously rolling. Sometimes all the coins (whether genuine or counterfeit) are returned to the return slot.
Currently, we are taking this approach.

However, even though I had put in specie coins at great length, I had to return these coins because I was continuously inserting coins.
5 has the drawback that users of automatic vending machines equipped with these coin sorting devices have to double the effort of inserting coins.

Furthermore, even if all of the above-mentioned inconveniences were solved, the coins that are routed to the specie passage beyond the gate would be placed in the respective safes corresponding to these coins, generally known as change pipes. As a method for taking the change into the change pipes when the coins are drawn into the coins, there is a well-known method of sorting the coins into these change pipes, that is, a hole slightly larger than the outer shape of each coin is made at the top of each change pipe in correspondence with the change pipe. When a coin suitable for taking in rolls around, it is taken in through which hole, but as mentioned above, if consecutive coins are taken in through the gate, the first coin will be taken in. Even while the change is being taken into the change pipe, subsequent coins try to climb over these taken-in coins and roll toward the corresponding pipe, so at this point the coins overlap each other and cause a coin jam. This also happened.

Therefore, the present invention focuses on this point and attempts to solve these points as well.

In other words, even if coins are continuously inserted as described above, the coins guided to the coin discriminating section always roll at a predetermined distance from subsequent coins, so it is difficult to use them in any condition. Not only can a reliable discrimination operation be obtained even when the coins are sorted, but also the coins that are guided to the gate and the window sorter on the change pipe are all rolled at a predetermined distance apart due to the influence of the vibrator mentioned above. Therefore, the gate can reliably sort the coins according to the discrimination operation of the coin discrimination section.

Furthermore, the respective window holes on the change pipe allow coins to be reliably taken in without jamming.

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are boards of a coin sorting device M that are arranged side by side with a gap 3 sufficient for transferring or moving coins C to be inserted; 4 is a board of a coin sorting device M; Coin input slot; 5 is a coin rail protruding from the base plate 2 into the gap 3 and inclined so that the input coins roll; 6 is a hardening rail 5;
The detection element 6 is a detection element of a coin discriminating section embedded in the substrate 2 in order to discriminate the authenticity (genuine coin or counterfeit coin) of the input coin C rolling above. The coin discriminating section is configured to discriminate the authenticity of a coin based on a phase change of voltage or current on the secondary side of the electromagnetic coil.

Reference numeral I designates a coin distribution gate that operates freely to move forward and backward into the gap 3 according to the discrimination control operation of the coin discrimination section.

8 is a specie passageway for taking specie coins into a safe (not shown), etc.; 9
is a counterfeit currency passage for guiding counterfeit coins to a return slot (not shown);
Reference numeral 10 denotes a coin sensor embedded in the substrate 2 to detect the presence or absence of an inserted coin above the coin rail 5, and the coin sensor is composed of an electromagnetic coil similar to the coin detection element 6 described above or a well-known phototransistor. ing.

Reference numeral 11 denotes a vibrator using an electromagnet or the like, and the vibrator is located above the coin sensor 10, and protrudes toward the coin path side, that is, the gap 3 side, and repeatedly performs a vibrating operation at least while the coin sensor 10 is detecting the inserted coin C. The inserted coin is stopped a plurality of times once it reaches the coin detection element 6.

Next, the operation of the device according to the present invention will be briefly described with reference to FIG. When this is confirmed, the protrusion 11' of the vibrator 11 that had been retracted to the board 2 side
immediately protrudes toward the coin passage side and repeats the vibrating operation in such a way as to press the coin C' detected by the coin sensor 10 toward the substrate 1. Then, the coin C' is affected by the vibrator 11 and moves normally. The transfer behavior is different from the transfer speed of .

In other words, the speed becomes low.

Next, when the coin C' rolls on the coin rail 5 due to its own weight and rolls away from the vibrator 11 and toward the coin discriminating section 6, the coin sensor 10 no longer detects the presence of the coin. The vibrator 11 also stops its operation, and the protruding portion 11' is retracted to the original substrate 2 side to enter a standby state.

Next, when the coin C' rolls to the coin detection element 6, the coin discrimination section determines the authenticity of the coin, and if it is a genuine coin, the coin distribution is Game) 7. A signal to evacuate from the passage side to the board 2 side is issued, the gate 7 is evacuated, and the discriminated coin C2 is transferred to a designated safe (not shown) or the like in the genuine coin passage 8.
Import via.

If the coin is a counterfeit coin, the coin discrimination section does not output a gate evacuation signal, so that the coin does not roll on the gate I and is guided to a return port (not shown) via the counterfeit coin path 9.

When coins are continuously inserted in such a state, the coin transfer speed of the input coins is controlled by the vibrator 11 at any time, so that the coin discriminator and the gate 7 can operate reliably. becomes.

Incidentally, it is preferable that the distance between the coins rolling from the vibrator 11 in the direction of the coin detection element 6 is determined by the performance of the game (game) 7. Generally speaking, the desired value is approximately the distance between the coins. It seems better to separate it by about 800m5eC.

Since the present invention has the above-described structure, even if coins are continuously inserted into the coin slot, the coin detection element and the sorting will not be transferred to the gate or the window sorting hole on the change pipe. The coins that come in always roll at a predetermined distance apart, so the coin discriminator and distribution are done by a gate, and the window on the change pipe is used to sort the coins through a window hole on the change pipe for reliable discrimination and distribution. It can be said that this is an excellent coin sorting device that is capable of taking in coins into a pipe.
