Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a counterfeit coin removing device that automatically removes counterfeit coins detected during coin sorting in a mixed coin sorting and counting machine.

<Prior art> Conventionally, the counterfeit coin removal means in a generally used coin sorting and counting machine is based on the function of a coin discrimination sensor placed in a coin passage, and a part of the coin passage is moved to the return side at 1v. It was just a matter of switching.

In other words, to date, this type of counterfeit coin removal has adopted a configuration in which coin feeding is temporarily stopped upon detecting a counterfeit coin, and all coins located in the coin passage (including genuine coins) are dropped into a return box. Not only did this result in a decrease in the efficiency of coin counting, but it was also necessary to select defective coins again from among the rejected coins. This appears as a particular drawback in a mixed coin sorting and counting machine that is equipped with a sorting passage having a chute for different denominations and handles a variety of coins.

<Purpose of the Invention> In view of the above-mentioned circumstances, the present invention aims to provide a counterfeit coin removal device that identifies counterfeit coins mixed during sorting and eliminates only counterfeit coins without affecting the sorting calculation function. This is what I did.

<Structure of the Invention> In the present invention, coins are fed out horizontally one by one using the centrifugal force of a rotary disk serving as a coin supply means, and are provided with a coin passage equipped with a coin sensor and a denomination-specific chute following the coin passage. In the mixed coin sorting and counting machine that leads to the sorting passage, a pair of coin discrimination sensors are placed in a hooked arrangement with the coin passage and the sorting passage facing each other on both sides, and a counterfeit coin return guide is provided at the tip of the coin passage, which is a straight path. is lowered to at least the conveying surface of the coin passage by a solenoid activated by the fake coin signal of the coin discrimination sensor, and only the fake coins are removed straight ahead, and the other genuine coins are moved along the curved wall surface of the guide to the sorting passage side. The structure is such that it can be used and transferred by hooking.

<Example> The present invention will be described below based on the drawings of the example.

Reference numeral 1 denotes a centrifugal force type coin supply unit comprising a rotary disk 2 on which coins A are placed and a cylindrical peripheral wall portion 3 erected on the peripheral edge 2a of the rotary disk 2;
A shutter-cum-guiding bending arm member 5 is provided on the outer side of a feed-out groove 4 having a width approximately the thickness of one coin cut out in the lower part of the peripheral wall portion 3, and which can be opened and closed and can move in and out of the feed-out groove 4 portion. The base of the coin passage 6 faces the tip of the bending arm member 5. This coin passage 6 has a take-in roller 7 at its base on the conveying surface 6a, a pair of endless conveying rollers 8 extending parallel to the conveying surface 6a over the entire area in front of the take-in roller 7, and a pair of endless conveying rollers 8 on both sides of an intermediate position. Opposed coin discrimination sensors 9.9 for detecting fake coins are provided, and a tapered roller 1o for width adjustment is arranged on the upper surface of one of the carrier-side conveyance loaves 8 at the positions of the coin discrimination sensors 9, 9. A fake coin removal device 12 is provided with a guide 11 for returning fake coins that can be freely descended at the tip. In this case, there is a tangential branch to the rotation 112 and 7.
- The wide conveyance surface 6a becomes narrow at the coin discrimination sensor position by the inclined guide portion 13a of the conveyance guide 13 disposed on one side. Reference numeral 14 denotes a sorting passage with a right-angled hooked arrangement on one side of the guide 11 at the tip of the coin passage 6 on the curved end 11a side. Type chute 16 for the number of denominations (1
, 5゜10.50, 100.500 yen coins) are sequentially arranged from the small diameter, and two coins are placed on this conveyance surface 14a.
A pair of transport ropes 17 are stretched in parallel 0, and the transport rope 1
A tapered roller 18 for pressing down coins is provided on the upper surface of the carrier section of the carrier section 17 at the position of each drop port 15, and
The denomination sensor 21 is disposed in front of the denomination 5. 2
Reference numeral 2 denotes an exclusion timing sensor provided on the conveying surface 6a that is the branching position of the coin passage 6 to the sorting passage 14; 23 denotes the guide 1;
This is a confirmation sensor interposed between the straight forward end of 1 and the return box 24 placed ahead of this.

To explain this operation now, first, the coin supply section 1, which serves as a coin supply tank, is filled with coins A group of appropriate denominations, and the rotary disk at the bottom of the coin supply section 1 is rotated. In this case, the solenoid 25 disposed at the base end of the shutter-cum-guiding bending arm member 5 located in the feed-out groove 4 portion of the peripheral wall portion 3 is turned off, and this side surface 5a is a tangent that serves as a feed-out guide for the rotary disk 2. Waiting in the coin passage 6
The counterfeit coin return guide 11, which has a curved wall surface 11b for lateral movement and is located at the straight conveyance end, is turned OFF when the solenoid 26 disposed at the lower end of the guide 11 is turned OFF and at least A protruding shape corresponding to the thickness of the coin is formed on the conveying surface 6a, so that the coin A traveling straight comes into contact with the curved wall surface 11b.

Here, when the rotary disk 2 rotates, the coins A group placed on the rotary disk 2 are distributed to the peripheral side by this centrifugal force and are lined up sequentially along the arc of the peripheral wall 3.
Proceed to the payout groove 4 side, which has a coin thickness width cut out in a part of the
One coin A is guided to the tip of the bending arm member 5 outside the feeding groove 4, and in this state, by pressure rotation of the constantly rotating take-in roller 7 located in the coin passage 6, one coin A is transferred to the conveying surface 6a side. Sent to. The coin A that has proceeded to this coin passage 6 is
The coin A is transported forward at high speed by an endless transport lobe 8 that rotates at a higher speed than the rotation of the take-in roller 7, and is separated from the coin A that follows. In addition, the position of the outer side edge Aa of the coin A advancing to the transport rope 8 is regulated by the inclined guide 13a arranged on one side, and the coin discrimination sensor 9,
At position 9, the inner side edge Ab of the two conveyor rollers 18 pressed against the upper surface of the coin A is moved outward by the taper action of the taper roller 10. That is, since the coin A takes a conveyance position in which the outer side edge Aa is securely in contact with the conveyance guide 13 by the lateral pressing of the tapered roller 10, accurate measurement can be performed by the coin discrimination sensors 9, 9. In this case, the coin discrimination sensor 9.9 uses a known counterfeit coin detection means.

In this state, when the coin A is a genuine coin, the solenoid 26 of the fake coin return guide 11 is not activated, and therefore the coin A that has proceeded through the coin passage 6 is stuck on the curved wall surface 11b of the guide 11.
The coins come into contact with the coins, move laterally along the curved wall surface 11b, proceed to the sorting passage 14 perpendicular to the coin passage 6, and are sent forward at the conveyance loaf 17 of the sorting passage 14. In this sorting passage 14, drop ports 15 corresponding to each denomination are arranged sequentially from the small diameter holes, so that, together with the downward pressure of the push-down tapered roller 18, the drop ports 15 fall into the drop ports 15 according to the denomination. Sorted into chute 16.

Next, when a fake coin is detected at the 9° 9 position of the coin discrimination sensor 9 of the coin passage 6, the shutter solenoid 25 is activated.
N, the bending arm member 5 is rotated to prevent the subsequent coin A from entering the coin passage 6, and then the next operation is started. When the fake coin A' that has passed through the coin discrimination sensors 9 and 9 reaches the removal timing sensor 22, the removal solenoid 26 is turned on and is placed in the machine frame 29 with the upper limit stopper 28 at the height of one coin. Since the regulated counterfeit coin return guide 11 descends so that at least the transport surface 6a and the upper guide surface 11c are on the same plane, the counterfeit coin A' that has advanced on this transport surface 6a has no contact wall. Therefore, it goes straight and falls into the return box 24. At this time, since the confirmation sensor 23 is interposed between the return box 24 and the guide 11, the number of fake coins is counted.

In addition, if two coins mA are jammed in the feeding groove 4 part of the coin supply section 1, and the coin passage time between the coin discrimination sensors 9 and 9 is longer than the setting (for example, 5 seconds),
The shutter solenoid 25 is turned on by the signal from the coin discrimination sensor 9.9, and the hooked base 5b of the bending arm member 5 rotates about the support shaft 30 in conjunction with the suction of the shaft 25a. The member 5 enters the feeding groove 4 at the peripheral edge 2a of the rotating disk 2, and forces the coin A (two coins) stuck horizontally into the feeding groove 4 to the center side of the rotating disk 2. Push it back to remove the bite. This rotation of the bending arm member 5 is performed three times, and the motor (not shown) is stopped one second after the third turn on.

<Effects of the Invention> As described above, the counterfeit coin removal device of the present invention has a coin passage provided with a coin discrimination sensor and a sorting passage connected thereto in a hooked arrangement, and a lateral transfer plate arranged at the tip of the coin passage. By configuring the counterfeit coin return guide, which serves as a contact wall, to be lowered by a solenoid activated by the signal from the coin identification sensor, only counterfeit coins are allowed to travel straight through the lowering of this guide and are automatically removed to the return side. Moreover, genuine coins can be moved to the sorting passage by placing them on the guide, allowing for highly efficient sorting.

Moreover, since the switching means of the present invention has an extremely simple structure, it can cope with high-speed mixed coin sorting and counting machines, and is of a robust type that does not cause failures or malfunctions.
