Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a coin sorting device for sorting and classifying a plurality of types of coins having different diameters.

[Conventional technology]

As one of the conventional coin sorting devices of this type, coins placed on a rotating disk are sent out from a coin delivery port into a linear passageway and moved on this passageway, and the opening width is set in this passageway. Some coins are provided with a plurality of coin drop ports having different diameters, and as coins of different diameters move on the passage, they fall from each coin drop port sequentially according to diameter.

However, if the passage for coin sorting is formed in a straight line like this, the entire device becomes large-sized, and moreover, the li! If the coins shift in the width direction of the passage, the sorting of the coins becomes uncertain, and there are problems such as the need to transport and guide the coins to prevent such shifts.

For this reason, as shown in, for example, TiTIB1155-28113, a passage is formed in the circumferential direction along the outer periphery of the rotating disk, and a coin drop opening is provided in this passage, thereby making the device more compact. In addition, there are devices that utilize centrifugal force to provide a coin guiding effect.

This device is schematically shown in FIGS. 6(a) and 6(b). In other words, a peripheral wall 102 is arranged above the periphery of the rotating circle llA101, and a coin C inserted into the peripheral wall 102
is fed and taken out from the coin sending port 103, and the rotating circle? A circumferential passage 104 facing the outer periphery of the rotating circle 1101 is formed around the ll
5 are arranged along the circumferential direction, and a guide plate 106 is provided on the outer peripheral side of the passage 104. Then, the hard coin 11C sent from the coin delivery port 103 to the passage 104 is transferred by the rotation of the rotating disk 101 while straddling the outer circumference of the rotating disk 101 and the rail 107 below the inner circumferential side of the guide plate 106. At the same time, the width of the coin drop port 105 (the distance between the rotating disk 101 and the guide plate 106) is expanded toward the front in the transfer direction, so that the coin C falls into a predetermined coin drop port 105 according to its type. Rotating circle W101 when reached
The various coins fall from each coin drop opening 105 in descending order of diameter.

[Problem to be solved by the invention]

According to the above device, the coin C on the passage 104 is
01, but a predetermined V1v4 drop port 10
5, it is necessary for the coin C to separate from the rotating disk 106. Therefore, the coin C being transferred is placed on the rotating disk 101 only a little, and the rotational force of the rotating disk 101 is sufficient for the coin C. It is difficult to reach. Therefore, coin slipping occurs, reducing the coin transfer ability, and variations in coin movement speed occur.As a result, coin sorting becomes uncertain due to pressure contact between coins during transfer, and high-speed processing becomes difficult. vAli.

Further, in this device, the coin C on the passage 104 is picked up by the guide plate 106 by centrifugal force, and furthermore, the coin C on the passage 104 is picked up by the guide plate 106, and
By making the coin C lower than the rotating disk 101 and tilting the coin C, the force of gravity is also applied toward the guide plate side. It is not possible to sufficiently prevent a situation in which the coin C floats up or shifts inward in the passage 104 when vibration occurs. When such a situation occurs, a coin C to be passed through a certain coin drop opening 105 may fall on the guide plate 1 as shown in FIG. 6(b).
The coins separate from the rail 107 on the 06 side and fall, making it impossible to sort coins correctly.

In view of these circumstances, the present invention aims to make the device more compact by sorting the coins while moving them in the circumferential direction, and also improves the efficiency of the sorting process by increasing the coin transfer capacity. The present invention provides a coin sorting device that can also increase the reliability of coin sorting.

[Means to solve the problem]

In order to achieve the above objects, the device of the present invention includes a rotating disk located below the coin slot and rotating in a fixed direction, and a device provided on a part of the surrounding wall surrounding the rotating disk to rotate the disk. A coin sending port that sends out coins one by one from the disk to the outside of the surrounding wall, a coin sorting passage arranged circumferentially around the surrounding wall, and a coin transfer mechanism that moves the coins on the coin sorting passage. The coin sorting passage has a guide wall protruding upwardly on the outer side of a coin supporting surface that supports the coins sent out from the coin sending port, and the coin sorting passage has a guide wall protruding upward on the outer side of the coin supporting surface that supports the coins sent out from the coin sending port, and a plurality of types of coins are arranged on the coin supporting surface. The coin transport mechanism has a plurality of coin drop openings arranged in the coin movement direction so as to sort and drop coins by diameter, and whose opening range in the width direction sequentially changes, and the coin transfer mechanism holds the coins above the coin supporting surface. The rotating member has an annular rotating member that rotates in a fixed direction, and the rotating member is provided with a coin feeding portion made of an elastic material and facing the coin supporting surface such that its lower end abuts the coin on the coin supporting surface. It is something that

In this device, it is desirable that the lower end of the coin feeding portion of the rotating member in the coin transfer mechanism be formed in a shape that is inclined or curved toward the outer circumferential side of the coin sorting passage.

Furthermore, it is desirable that the guide wall of the coin sorting passage and the rotary member are arranged such that the rotary member approaches the guide wall toward the front in the coin transport direction, at least within the range where the coin drop ports are arranged.

[Effect]

According to the above configuration, while the coins are moving along the guide wall on the coin sorting path, the coins with the smallest diameter fall into each coin drop slot and are sorted.
The coin feeding portion of the rotating member reliably transports coins, and also has the effect of inhibiting coins from floating up or moving toward the inside of the passage.

In particular, if the lower end of the coin feeding portion is formed in a shape that is inclined or curved toward the outer circumferential side of the coin sorting passage, the effect of inhibiting the movement of coins inward of the passage is enhanced. Furthermore, if the guide wall of the coin sorting passage and the rotating member are arranged such that the rotating member approaches the guide wall toward the front in the coin transport direction at least within the range where the coin drop openings are arranged, the coins will be removed as they are transported. The effect of pressing against the guide wall is increased by -II.

〔Example〕

Embodiments of the present invention will be described based on FIGS. 1 to 5.

Reference numeral 1 denotes a fixed base, which is fixed within a casing (not shown) that houses the coin sorting device. A rotating disk 2 is provided above the fixed base 1.

This rotary disk 2 is rotatably supported by a fixed support W1 via a bearing 3, and is connected at its center to a drive shaft 4, so that power from a motor 5 is transmitted to the drive shaft 4. The rotating disk 2 is configured to rotate in a fixed direction (arrow A in FIG. 1). This rotating circle a2 is located below a hopper (coin input port, not shown) provided above the casing, and multiple types of coins C with different diameters are thrown into the rotating circle 111 from the hopper. It has become.

The rotating circle above! 12, there is an enclosure I! fixed on the fixed word 11 and surrounding the rotating circle a2! 6 is provided. A part of this surrounding wall 6 is opened, and an upper wall 7 of the outlet is provided in this open part at a constant interval with respect to the upper surface of the rotating disk 2, so that there is a gap between the upper wall 7 of the outlet and the rotating circle I12. , a coin delivery port 8 for delivering coins one by one from the rotating disk 2 to the outside of the surrounding wall 6 is formed.

A plate 9 forming a coin sorting passage 10 is arranged outside the surrounding wall 6, and this plate 9 is fixed on the fixed base 1. A certain area of the plate 9 around the surrounding wall 6 is approximately at the same height as the rotating disk 2, and a coin supporting surface 11 is formed by this area.

The coin support surface 11 has a circular outer shape concentric with the rotating circle 12, and a guide wall 12 that projects upward in a stepped manner is provided on the outer periphery of the coin support surface 11.

An auxiliary feeding mechanism such as a belt 13 is provided on the starting end side of the coin sorting passage 10 corresponding to the coin discharging opening 8 in order to assist in sending out coins from the coin dispensing opening 8 to the coin sorting passage 10. A delivery guide piece 14 is provided that extends from both sides of the coin delivery port 8 of the surrounding wall 6 toward the guide wall 12.

A plurality of coin drop ports 15a, 15b, . . . are opened in the coin support surface 11 of the coin sorting passage 10 for sorting and dropping a plurality of types of coins C according to their diameters. Six coin drop ports 15a to 15f are opened to correspond to six denominations of coins. These coin drop ports 158 to 15f are arranged in the direction of arrow B) in the coin movement direction, and the width of the opening is sequentially expanded toward the inner side of the passage so that coins with smaller diameters are dropped in order. The outer side of each coin drop port 158 to 15f and the guide wall 12
A coin support surface 11 of a narrow constant width is left between the coin support surface 11 and the coin support surface 11. In addition, chutes 16 are provided below each of the coin drop ports 15a to 15f, and each coin drop 0.
Coins falling from 158 to 15f are sent through the chute 16 to a classified coin storage section (not shown).

An annular rotating member 20 constituting a coin transfer mechanism is provided above the coin sorting passage 10.

This rotating member 20 consists of a metal ring 21 having a pulley portion 21a at the top, and a coin feeding belt (coin feeding portion) 22 fixed to the lower end of this ring 21.
Shafts 2 erected at multiple locations inside the coin sorting passage 10
The ring 21 is held rotatably above the coin support surface 11 by being locked to the O-ra 24 at the upper end of the coin support surface 11. A transmission belt 26 is passed between the pulley portion 21a of the ring 21 and a pulley 25 located outside the coin sorting passage 10, and the power transmitted from the motor 5 moves the coins in a fixed direction. The rotating member 20 is configured to rotate.

The coin feeding belt 22 is made of an elastic material such as rubber,
The lower end faces the coin support surface 11 so as to elastically abut the coin on the coin support cylinder 11. In particular, in the case of five coins, the lower end 122a of the coin feeding belt 22 is formed to be inclined or curved toward the outer circumferential side of the coin sorting passage.

In addition, in the case of five coins, the guide W112 of the coin sorting passage 10 and the rotating member 20 are arranged so that the rotating member 20 becomes closer to the guide wall toward the front in the coin transfer direction at least in the range where the coin drop ports 15a to 15f are arranged. 12, that is, the guide walls 1
The rotating member 20 is arranged such that the rotation center 02 of the rotating member 20 is shifted in a predetermined direction from the curvature center 01 of the rotating member 2 (see FIG. 4).

In addition, the above rotation circle%! 2, the rotating member 20, and the belt 13 of the auxiliary feeding mechanism are simultaneously driven by one motor 5. That is, in the example shown in the figure, the power from the motor 5 attached to an appropriate location such as the lower surface of the fixed base 1 is transmitted to the relay pulley 28 via the belt 27, and is further transmitted to the belt from the pulley 29 coaxial with this pulley 28. 30, the rotation is transmitted through the pulleys 31, 32, and the belt 33 to the pulley 34 provided on the drive shaft 4 of the same rotation circle N2, while the rotation is transmitted from the pulley 25 coaxial with the pulleys 28, 29 through the belt 26 to the rotating member. Rotation is transmitted to 20.

In addition, the belt 13 of the auxiliary feed mechanism is also equipped with a transmission belt (not shown).
According to the coin sorting device having the structure described above, a large number of coins of different types with different diameters are thrown onto the rotating disk 2. At the same time, by driving the coin R1, the coins C are sent out one by one from the coin delivery port 8 to the coin sorting passage 10 by the centrifugal force caused by the rotation of the rotating circle W2, and the coins C are sent out one by one to the coin sorting passage 10 on the outer circumferential side of the coin sorting passage 10. , and enters between the coin supporting surface 11 and the lower end 22a of the coin feeding belt 22 of the rotating member 20. The movement of the coin C at this time is assisted by the belt 13 of the auxiliary feeding mechanism.

The coin C moved to the coin sorting passage 10 is guided! 12
move in the circumferential direction along the In this case, the coins C are transported by the coin transport belt 22 of the annular rotating member 20 corresponding to the coin sorting passage 10, and the coin transport capacity is sufficiently increased to accommodate high-speed processing. Further, centrifugal force acts on the hard g4C moving in the circumferential direction on the coin sorting passage 10, and this centrifugal force causes the coin C to move toward the guide wall 12.
At the same time, the lower end of the coin feeding belt 22 comes into elastic contact with the upper surface of the coin C, thereby suppressing the floating of the coin C or movement toward the inside of the passage due to vibrations or the like.

In particular, in the case of five coins, the lower end 22a of the coin feeding belt 22
is formed in a shape that is inclined or curved toward the outer circumferential side of the coin sorting passage, as shown in Fig. 3, it does not prevent the movement of the coin C toward the outer circumferential side of the passage due to centrifugal force, but it A restoring force due to the deformation of the belt lower end 22a as shown by the two-dot chain line acts on the movement of the coin C in this direction. Therefore, the effect of suppressing the shift of the coin C toward the inside of the passage is enhanced.

Furthermore, by making the guide wall 12 and the rotating member 20 eccentric as described above, the effect of suppressing the displacement of the coin C is enhanced by -II. In other words, the guide wall 12 shown in FIG.
Eccentric arrangement of the rotating member 20 and the distance d1, d2 between the guide wall 12 and the rotating member 20 as you move forward in the direction of movement
... gradually becomes smaller, and as the coin C moves along the guide wall 12, the coin C relative to the rotating member 20
The relative position of is gradually displaced inward. As a result, a restoring force due to the deformation of the lower end portion 22a of the belt as shown by the two-dot chain line in FIG. The cargo C will be pressed against the guide wall 12.

While the coins C move along the guide g12 in this manner, various coins C having different diameters fall into the corresponding coin drop ports 15a to 15b and are sorted. In other words, first, at the first coin drop 015a, the smallest diameter coin C
1 (one yen coin) gets lost, the coin C1 separates from the coin support surface 11 on the inner side of the coin drop port 15a and falls from the coin drop port 15a, as shown by the solid line in FIG. The larger diameter coin C2 passes through the coin drop port 15a by straddling the coin support surfaces 11 on both the inner and outer sides of the coin drop port 15a, as shown by the broken line in FIG.

In this case, 1! to the inside of the aisle! Since the coin shift is suppressed, the coin C2 that should pass through the coin drop port 15a
This prevents the coin from coming off the coin support surface 11 on the outer side of the coin drop opening 15a. Further, the lower end portion 22a of the belt is moved by an elastic pressing force from above.
It also has the effect of accelerating the fall of the coin C1. Below, other coins are created in the same way, starting with the smallest diameter (50 yen coin, 5 yen coin, 100 yen coin, 10 yen coin, 500 yen coin)
The coins fall into the coin drop ports 15b to 15f, respectively.

Further, this coin sorting device can also incorporate a device for counting each sorted coin.

In this case, each coin falling 01 in the coin sorting passage 10
Coin counting mechanisms 35a to 3 are located in front of 58 to 15f, respectively.
5f is provided, the difference between the count values of two successive coin counting mechanisms becomes the number of coins that have fallen into the coin drop openings 158 to 15e located between them, and the final coin counting mechanism 35f. Count value! &Final coin drop opening 1
This is the number of coins that fell on the 5th floor. Therefore, the outputs of each of the counting mechanisms 35a to 35f may be input to a performance processing section (not shown) to calculate the number of coins for each denomination, and then store, total, display, etc.

In addition, as a structure in which the rotating member 20 approaches the guide wall 12 of the coin sorting passage 10 as it approaches the front side in the coin transfer direction in the vA area in which at least the coin drop ports 158 to 15f are arranged, the above-mentioned structure is adopted. Circular guide as in the example! ! 12 and the rotating member 20 are eccentrically arranged relative to each other, the guide! ! 12 may be an ellipse or a cam curve shape in which the curvature of the portion over a predetermined range changes,
Alternatively, the guide wall 12 may be formed into such a shape, and then the rotating member 20 and the guide wall 12 may be arranged eccentrically. Therefore, the coin sorting passage 10 whose outer shape is determined by the guide wall 12 is not necessarily arranged in a perfect circular circumferential shape, but is arranged along the circumferential direction of an ellipse or the like. A coin sorting passage having a coin supporting surface and a guide wall and having a plurality of coin drop openings arranged is provided around the outer circumference of a rotating disk that sends out coins from a coin sending port by centrifugal force. Separately, a coin transport mechanism is provided on the coin sorting passage in which a coin transporting part made of an elastic material is provided on an annular rotating member, and the lower end of the coin transporting part is in contact with the coins. Compared to a system in which coins are transferred using a rotating disk, the coin transfer capacity is improved and the transfer speed can be increased. Furthermore, the coin feeding portion in contact with the top surface of the coin prevents the coin from floating or shifting during vibration, and also has the effect of speeding up the fall of the coin at the predetermined coin drop opening. Therefore, coins can be sorted quickly, efficiently, and accurately.

Furthermore, the lower end of the coin feeding portion is inclined or curved toward the outer circumferential side of the coin sorting passage, and the guide wall of the coin sorting passage and the rotating member are arranged such that at least coin drop openings are arranged. By arranging the rotating member so that it approaches the guide wall toward the front in the coin transport direction, the effect of preventing the coin from shifting during transport will be further enhanced.
The reliability of selection can be increased.
