BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorting / sorting machine which separates coins mixed with various denominations for each denomination.

[0002]

2. Description of the Related Art Conventionally, as a coin sorting / sorting machine for separating coins of various denominations into coins of each denomination, Japanese Patent Laid-Open No. 59-20 is known.
Those disclosed in Japanese Patent No. 8684 can be cited.
This coin sorting / sorting machine conveys multi-denomination mixed coins one by one while pressing them against guide rollers, which are guide members, and sorts coins by denomination by a plurality of holes arranged in the conveying direction. Then, the sorted coins are dropped into the storage corresponding to the holes for classification, and the plurality of holes are separated from the guide rollers by a predetermined amount at the positions of the guide rollers. The position on the side opposite to the guide roller and the distance between the guide roller and the guide roller are configured such that the distance to the downstream side in the conveying direction becomes larger according to the diameter of the coin to be selected.

Then, when the coin pressed against the guide roller is, for example, a one-yen coin having the smallest diameter, the one-yen coin is provided on the side opposite to the guide roller of the hole at the most upstream side in the conveying direction. Since it will pass inside the position (guide roller side), it falls into this hole and enters the storage
When a coin having a diameter larger than this passes through the hole for the one-yen coin, the coin will pass outside the position of the hole for the one-yen coin opposite to the guide roller. Does not fall, but passes through the hole, reaches a predetermined hole that can be dropped, and drops. In this way, coins having different diameters are dropped from the corresponding holes and separated.

[0004]

However, in the coin sorting / sorting machine having the above-mentioned structure, when coins are scratched or dust adheres to the coins and the outer peripheral surface of the coins cannot contact the guide rollers, Depending on the size of scratches, dust, and the like, coins that do not correspond to the holes can be inserted (that is, erroneously selected) from the guide roller side of the hole located at a predetermined distance from the guide roller. Then, the misselected coins are dropped from the holes that do not correspond and are stored in the storage, so it is very difficult to find the misselected coins from the storage. It was

Therefore, an object of the present invention is to provide a hole at a position separated from the guide member by a predetermined amount from the guide member side,
Even if a coin that does not correspond to the hole may enter, a coin that prevents the missorted coin from falling through the hole and eliminates the need to perform a very complicated work of finding the missorted coin from the storage box. It is to provide a sorting and classifying machine.

[0006]

In order to achieve the above object, a coin sorting and classifying machine according to claim 1 of the present invention conveys coins of different denominations one by one while being pressed against a guide member. , A position on the side of each of the guide members is separated from the guide member by a predetermined amount, and a distance between the position on the side opposite to each of the guide members and the guide member is a downstream side in the transport direction according to the diameter of the coin to be selected. The coins are sorted by a plurality of holes that become larger, and the sorted coins are dropped into the storage corresponding to the holes to sort the coins. It is characterized in that a drop restricting means for restricting the falling of the coin from the is provided.

The coin sorting and classifying machine according to a second aspect of the present invention is, in addition to the coin sorting and sorting machine according to the first aspect, provided with detection means for detecting the presence or absence of coins whose falling is regulated by the fall regulating means. It is characterized by

DESCRIPTION OF THE PREFERRED EMBODIMENTS A coin sorting / sorting machine according to an embodiment of the present invention will be described below with reference to FIGS.

The overall construction of the coin sorting and classifying machine of this embodiment is as follows.
This is almost the same as the coin sorting / classifying machine described in Japanese Patent Application Laid-Open No. 63-250792, which the applicant of the present invention has previously filed. That is, as shown in FIG.
A turntable 1 rotatably provided in a clockwise direction and a counterclockwise direction by driving a motor (not shown) and coins C (not shown in FIG. 1) fed one by one from the turntable 1 are inserted. It has a discriminating path 3 which has an inlet 2 and whose downstream side in the coin conveying direction is curved in a substantially right angle direction, and a sorting path 4 which is provided on the downstream side of the discriminating path 3 in the coin conveying direction.

The discriminating path 3 is provided between a pair of guide plates 5 and 6 extending in parallel with each other. In the discriminating path 3, a material sensor 7 such as a magnetic sensor or a conductive sensor for detecting the material of coins passing between the guide plates 5 and 6, and a photo array for detecting the diameter of the passing coin C, a CCD. A diameter sensor 8 such as a sensor or an image line sensor is sequentially provided along the conveyance direction, and a downstream side of the diameter sensor 8 in the conveyance direction is driven by a solenoid (not shown) to project into the determination path 3 and pass therethrough. A stopper 9 for restricting the movement of the coin C to be tried is provided. An opening / closing plate 10 that is opened and closed by being driven by a motor (not shown) is provided in the determination path 3 at the position where the stopper 9 is provided. The opening / closing plate 10 should be opened by driving the motor (not shown). Thus, the coin C, the movement of which is restricted by the stopper 9, on the opening / closing plate 10 slides down into the reject storage (not shown). A guide plate 11 having a substantially arc shape that changes the moving direction of the coin C by about 90 ° is provided on the downstream side of the guide plate 5 on the left side in FIG.
The discriminating path 3 is curved by 1 and is connected to the sorting path 4.

2 is separated by a predetermined amount and is parallel to the side portion 19,
The distance between the side portion 20 on the side opposite to the reference guide plate 12 and the reference guide plate 12 is larger on the downstream side in the transport direction according to the diameter of the coin C to be selected. That is, for example, the hole 15 on the most upstream side in the transport direction is formed such that the distance between the side portion 20 and the reference guide plate 12 is slightly larger than the diameter of the smallest yen coin and smaller than other coins. Of the coins that are conveyed in contact with the reference guide plate 12, only one-yen coins enter the side portion 20 and fall, and other coins pass through. In this way, the hole 16 is a fifty-yen coin, the unillustrated hole on the downstream side of the hole 16 is a five-yen coin, and the unillustrated hole on the further downstream side is a hundred-yen coin in this order along the carrying direction. Further, a hole (not shown) on the further downstream side can drop a ten-yen coin and a hole (not shown) further downstream can drop a five hundred-yen coin. Each of the holes 15 and 16 is provided with a storage box (not shown) for separately storing the coin C falling from the corresponding hole.

Further, above the discriminating path 3 and the sorting path 4, there is provided a feed belt 21 which is driven by a motor (not shown) and conveys the coin C from the discriminating path 3 to the sorting path 4 (see FIG. 9). .. The portion of the feed belt 21 on the sorting path 4 is pushed along the conveyance direction in order to convey the coins C one by one while sequentially pressing them against the reference guide plate 12.
It is inclined to approach.

In the present embodiment, the holes 15, 1
6 is a bracket 22 which is a drop restricting means for restricting the fall of the coin C from the side portion 19 on the reference guide plate 12 side.
Is provided. This bracket 22 is shown in FIGS.
As shown in FIG. 2, when the mounting plate 23 is attached to the rear surface side of the sorting path 4 so as to correspond to the holes 15 and 16, almost half of the semicircular hole portions 18 of the holes 15 and 16 on the upper side in FIG. 2 for closing the main semi-circular hole closing portion 24 and the lower half of the semi-circular hole portion 18 in FIG.
The main rectangular hole closing portion 25 that closes the reference guide plate 12 side of No. 7 such that the closing area becomes smaller (although it does not become 0) from the substantially intermediate position between the side portions 19 and 20 toward the downstream side in the transport direction. And has a main square hole closing portion 25.
Since the surface portion 26 of the positively regulates the falling of the coin C,
It is inclined so that its position becomes lower as it goes toward the reference guide plate 12 side (see FIG. 4).

In addition, each hole 15, 1 of the main square hole closing portion 25
A magnetic sensor 28, which is a detecting means for detecting the presence or absence of the coin C whose falling is regulated by the bracket 22 and detecting the falling coin C, is provided on the end edge portion 27 facing the upper end 6 of the coin C. It is provided by inclining at a predetermined angle with respect to the falling direction of.

The magnetic sensor 28 does not detect the holes of coins C (five-yen coins and fifty-yen coins) so that each hole 1
When the coin C whose falling is regulated is almost in contact with the side portion 30 on the downstream side of the conveying direction of 5, 5 or each hole 15,
When the coin C dropped inside the coin 16 passes in front of the magnetic sensor 28, the resolution of the portion corresponding to the hole position of the coin C is lowered, and the coin C whose falling is regulated is the side portion 3
0, or when each hole 15, 1
When the coin C dropped in the coin 6 passes in front of the magnetic sensor 28, the resolution of the gap between the coin C and the next coin C is increased. Specifically, FIG.
And a flat ferrite core as shown in FIG. 6, or as shown in FIGS. 7 and 8, a plurality of pot-shaped ferrite cores 31 that are small enough to be arranged at positions where coin hole positions can be ignored ( It is possible to employ a molded product or the like, which is two in the illustrated example. Since the circuit portion (not shown) of the magnetic sensor 28 is a high-frequency circuit, it is built in the bracket 22 as an integrated type with the magnetic sensor 28 and shielded so as not to be influenced by other metals. The bracket 22 does not react with the coins C passing over the holes 15 and 16 at all and falls in a fixed posture with respect to the holes 15 and 16, or the coins C whose dropping is restricted.
The magnetic sensor 28 is attached to the sorting path 4 by adjusting the angle and the like so that only the magnetic sensor 28 is detected.

The magnetic sensor 28 is used in the rotating disk 1
Connected to a drive motor (not shown) and a drive motor (not shown) of the feed belt 21 and the like, which is connected to a control device (not shown) that controls the entire coin sorting / sorting machine. It is designed to output a detection signal.
The controller is connected to the material sensor 7, the diameter sensor 8, the driving solenoid (not shown) of the stopper 9 and the driving motor (not shown) of the opening / closing plate 10, and the alarm device (not shown). Is also connected to.

Next, the operation of the coin sorting / sorting machine having the above construction will be described below. First, when the coin C mixed with various denominations is supplied to the turntable 1 and the coin sorting / sorting machine is started, the turntable 1 rotates counterclockwise in FIG. 1, and the coin C on the turntable 1 is centrifuged. A force is applied to reach the peripheral edge of the turntable 1 and the discs 3 are continuously made one by one from the inlet 2
Send to. Then, the feed belt 21 in the driven state is a coin C.
While passing pressure, the material sensor 7 and the diameter sensor 8 are passed. At this time, the control device compares the data output from the material sensor 7 and the diameter sensor 8 with the reference data of the coin C which is divided and stored in advance for each denomination, and passes through the discrimination path 3. The denomination of the coin C to be processed is determined, and when the passing coin C corresponds to any denomination, the counter provided for each denomination is counted up, and the coin C is kept as it is. Send to the side. On the other hand, when the passing coin C does not correspond to any denomination, the solenoid (not shown) is driven to cause the stopper 9 to project and the motor (not shown) is driven so as to prevent the coin C from being conveyed to the sorting path 4. The open / close plate 10 is driven to open and the coin C stopped by the stopper 9 is stored in the reject storage.

The coin C having passed through the opening / closing plate 10 has its conveying direction changed by the feed belt 21 and the guide plate 11.
Further, the sorting belt 4 is conveyed by the feed belt 21 while being pressed against the reference guide plate 12. Then, the coin C pressed against the straight side portion 14 of the reference guide plate 12 and conveyed is the side portion 20 on the side opposite to the reference guide plate 12.
If there is a hole whose distance between the reference guide plate 12 and the reference guide plate 12 does not correspond, it passes over this hole, and as shown in FIGS. 9 and 10, from the hole corresponding to the distance (hole 15 in the illustrated example) to the bracket. It will fall through the opening 32 of 22 into the storage (not shown). At this time, the magnetic sensor 28 detects the falling coin C and outputs the detection signal to the control device. Then, the control device counts down the denomination counter corresponding to the magnetic sensor 28 that has output. When the value of this counter becomes a negative value or becomes a positive value above a predetermined value, it is considered that an abnormal sorting of the coins C has occurred, and for example, the sorting and separating operation is stopped and the feeding belt is stopped. 21 is rotated in the reverse direction to return the coin C in the discrimination path 3 or the like to the turntable 1 side,
Output to an alarm device (not shown) to display an alarm.

Here, in the case where, for example, the coin C is damaged or adheres to dust and cannot be brought into contact with the reference guide plate 12 on its outer peripheral surface, the coin C will be
Also, as shown in FIG. 12, even if the holes (holes 15 in the illustrated example) that do not correspond may enter the hole 15 from the side 19 side of the reference guide plate 12 side, the reference guide plate 12 of this hole 15 Since the side is closed by the bracket 22, the hole 15 cannot fall from the side 19 of the reference guide plate 12 of the hole 15. Then, the coin C in a state in which it cannot be dropped enters the hole 15 on the side of the reference guide plate 12 and is inclined on the side opposite to the reference guide plate 12 on the sorting path 4, and is fed next in this state. It is pushed by the coin C and substantially comes into contact with the side portion 30 of the hole 15. At this time, in the detection signal of the coin C output from the magnetic sensor 28 to the control device, the waveform of the coin detection state does not change for a longer time than usual as shown by g in FIG. 13 (a to f is a waveform when the coin C is normally dropped, g is a waveform when the coin C is regulated to be dropped, and its vertical axis represents the magnitude of the output voltage). When the waveform does not change for a predetermined time, for example, the sorting operation is stopped and the feed belt 21 is rotated in the reverse direction to return the coin C in the discriminating path 3 or the like to the turntable 1 and to an alarm device (not shown). Output and display alarms.

As described above, according to the coin sorting / classifying machine of this embodiment, the holes 1 provided corresponding to all denominations are provided.
Even if the coins C that do not correspond to the holes 15 and 16 may enter the brackets 22 of 5 and 16 from the reference guide plate 12 side of the holes 15 and 16 due to scratches or adhesion of dust on the coins C. Coin C from the reference guide plate 12 side of the holes 15 and 16
Will be regulated. Therefore, since the coin C does not drop from the non-corresponding hole, the coin C can be easily removed from the hole, and it is necessary to perform a very complicated work of finding the misselected coin from the storage. Can be eliminated. Moreover, by the magnetic sensor 28,
The presence or absence of the coin C whose falling is regulated by the bracket 22 can be detected. Therefore, due to the presence of the coin C whose falling is regulated by the bracket 22, it is possible to stop the drive of the coin sorting / sorting machine, generate an alarm, and the like.

In the above embodiment, the guide member using the reference guide plate 12 having the straight side portion 14 has been described as an example. However, the guide member is not limited to this. For example, a plurality of guide rollers may be used. A good effect is exhibited even when using an array or the like. Although the magnetic sensor 28 is adopted as the detecting means, the detecting means may be any sensor as long as it can detect the presence or absence of coins.

As described in detail above, the first aspect of the present invention
According to the coin sorting and classifying machine described above, the drop restricting means provided in each hole may cause coins that do not correspond to the hole to enter from the guide member side of the hole due to scratches or adhesion of dust on the coin. Also regulates the fall of coins from the guide member side of each hole. Therefore, since coins do not drop from the holes that do not correspond, it is possible to easily remove this coin from the hole, eliminating the need for the extremely complicated work of finding a missorted coin from the storage. can do.
