Description

The present invention relates to a coin sorting device for a coin processing machine.

[Conventional technology]

In a coin processing machine, it is usually required to sort out coins containing various denominations supplied for each denomination,
Generally, a coin sorter is provided. As such a coin sorter, a coin sorter that sorts coins supplied in a state in which various denominations are mixed is widely used by utilizing that the outer diameter of the coin is different for each denomination. According to Japanese Patent Application No. 62-252202, the applicant first selects a coin having a larger outer diameter than a coin to be sorted (hereinafter referred to as "set coin") (hereinafter referred to as "large-sized coin"). By removing, and then removing a coin with an outer diameter smaller than the set coin (hereinafter referred to as "small coin"),
It proposes a coin sorting device configured to effectively sort only set coins.

FIG. 3 is a schematic plan view of a coin sorting device proposed by Japanese Patent Application No. 62-252202, and FIG. 4 is a schematic front view thereof. As shown in FIG. 3 and FIG.
In the coin sorting apparatus 1 according to No. 252202, the coins fed from the rotary disc 2 are conveyed to the guide passage portion 4 by the coin conveying belt 3. The guide passage portion 4 includes a guide plate 5 and a coin guide member 6, and the coin guide member 6 is
It has an inclined surface 7 that rises in the coin advancing direction, a horizontal surface 8 that is continuous with the inclined surface 7, a side surface 9, and a curved surface 10 that is continuous with the side surface 9. The side surface 9 is arranged in parallel with the guide plate 5 at an interval equal to the outer diameter of the set coin. further,
A coin passage restricting arm 12 is provided so as to be swingable around a shaft 11 and covers the inclined surface 7. arm
The spring 12 is biased counterclockwise in FIG. 3 by the spring 14, and its position is regulated by contacting the pin 22 so that the linear portion 13 is on the same straight line as the side surface 9. There is. Since the widths of the straight part 13 and the side surface 9 of the arm 12 and the straight part 15 of the guide plate 5 are the same as the outer diameter of the set coin, the set coin and the small coin have the side face 9 and the guide plate 5.
The coins are conveyed by the coin conveying belt 3 along the direction, the conveying direction is changed through the curved surface 10, and the coin conveying belt 16 guides the coins to the coin accommodating means 17. Here, the set coin is guided to the coin guide portions 18a and 18b having the same width as the outer diameter of the set coin and is stored in the set coin storage portion (not shown), while the small coin is the coin guide portions 18a and 18b. The coin is dropped into the hollow portion 19 having a width slightly larger than the outer diameter of the small-sized coin formed in the middle thereof and is stored in the small-sized coin storing portion (not shown). on the other hand,
The large-sized coin guided to the guide passage portion 4 contacts the linear portion 13 of the arm 12 while keeping one side in contact with the linear portion 15, but the arm 12
Since the interval between the straight line portion 15 and the straight line portion 15 is set to be equal to the outer diameter of the set coin, the large-diameter coin is shown in FIG.
11 Swing clockwise around. The large-diameter coin further rides on the horizontal plane 8 through the inclined surface 7 on the other side while keeping one side in contact with the straight line portion 15, and is conveyed by the coin conveying belt 3 in the inclined state. Since one side of the large-sized coin rides on the horizontal plane 8, the traveling direction of the large-sized coin cannot be changed by the curved surface 10, and the large-sized coin is transported over the curved surface 10 by the coin transport belt 3 and dropped into the large-sized coin discharge port 20. Then, the coin is stored in a large coin storage section (not shown) below the large coin discharge port 20. Arm 12 has a large-diameter coin
After passing the end point 21 of 13, the elastic force of the spring 14 returns the initial position, that is, the position where the linear portion 13 is on the same straight line as the side surface 9, and the set coin or the small-diameter coin rides on the inclined surface 7, and the coin remains as it is. The conveyor belt 3 is configured to prevent accidental conveyance to the large-diameter coin discharge port 20.

[Problems to be solved by the invention]

In this coin passage restriction arm 12, only large-sized coins ride on the horizontal plane 8 via the inclined surface 7 on one side,
The purpose is to allow the coin transfer belt 3 to convey the coins to the large-diameter coin discharge port 20 in an inclined state without changing the traveling direction of the large-diameter coins. , When the set coin or the small-diameter coin is conveyed after passing the end point 21 of the coin passage restriction arm 12 and the arm 12 returns to the initial position, the set coin or the small-diameter coin is transferred to the inclined surface 7. Although it is possible to prevent riding up, the arm 12 cannot return to the initial position until the large coin passes through the end point 21 of the linear portion 13 of the arm 12, so that the arm 12 is in the original position. Before returning to, if the set coin or the small coin is continuously conveyed immediately after the large coin, the set coin or the small coin is transferred together with the large coin by the coin passage restriction arm 12.
The transport path is guided without being restricted, and the limited coin or the small-diameter coin rides on the inclined surface 7, and the coin-transport belt 3 passes through the horizontal plane 8 and the large-diameter coin outlet 20 as it is. There was a problem that it might be transported to.

In view of this point, the present invention prevents a set coin or a small-diameter coin from riding on the inclined surface 7, and can reliably select the set coin from the coins supplied to the coin processor. The purpose is to provide a sorting device.

[Means for solving the problem]

The object of the present invention is that the coin sorting device of the coin processor, in place of the coin passage restriction arm 12, is reciprocally movable in a direction substantially perpendicular to the guide plate and is urged toward the guide plate.
On the bottom surface immediately before the inclined surface or on the inclined surface, the distance between the lower surface and the bottom surface immediately before the inclined surface or the inclined surface is smaller than the thickness of the smallest coin, and The distance from the straight line portion is achieved by providing a projecting portion that is settable below the outer diameter of the coin to be sorted.

According to the present invention, the conventional coin passage restriction arm 12 cannot reliably prevent the set coin or the small-diameter coin that is continuously conveyed immediately after the large-diameter coin from riding on the inclined surface 7 because the arm 12 has a straight line. Since the portion 13 contacts the large-diameter coin, the arm 12 cannot return to its initial position until the large-diameter coin has finished passing through the end point 21 of the linear portion 13, and therefore returns to the initial position. This is based on the finding that it cannot be reliably guided by the previously set coins or small-diameter coins.

In a preferred embodiment of the present invention, the horizontal surface further has a protrusion that protrudes toward the guide plate from the position before the end point of the guide plate to between the bent surfaces,
The distance between the lower surface of the protruding portion and the bottom surface of the guide passage portion is set to be equal to or greater than the thickness of the thickest coin among the set coins and the small diameter coins.

With this configuration, even when there is not much difference in the outer diameters of the coins, it is possible to more effectively prevent the set coins and the small coins from riding on the inclined surface and being mistakenly sent to the large coin ejector. It becomes possible to prevent.

[Action]

According to the present invention, the large-sized coin is prevented from coming into contact with the linear portion of the arm, and the large-sized coin is only brought into contact with the portion provided in the projecting shape, so that the set coin or the small-sized coin should be mounted on the inclined surface. Also, it is pushed out in the direction of the guide plate by the projection provided on the bottom surface immediately before the inclined surface or on the inclined surface, and the distance between the side surface of the coin guide member and the linear portion of the guide plate is outside the set coin. Since the diameter is set to be equal to or smaller than the diameter, the set coin or the small-sized coin is directly conveyed to the guide passage portion. On the other hand, since the outer diameter of the large-diameter coin is larger than the distance between the protruding portion and the straight portion of the guide plate, the large-sized coin conveyed while in contact with the guide plate moves the protruding portion away from the guide plate. It is rocked, rides on the inclined surface, and is stored in the large-diameter coin storage means. After the passage of the large coin, the protruding portion immediately returns to the initial position, that is, the position on the same side as the side surface of the coin guide member, and the inclination of the set coin or the small coin conveyed continuously immediately after the large coin. It is possible to prevent riding on the surface. Further, since the distance between the lower surface of the protruding portion and the inclined surface is smaller than the thickness of the coin having the smallest thickness, the coin does not enter below the protruding portion and ride on the inclined surface. It becomes possible to separate the diameter coin from the set coin and the small coin.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.
Add a detailed description.

FIG. 1 is a schematic plan view of a coin sorting device according to an embodiment of the present invention, and FIG. 2 is a schematic front view thereof.

In FIG. 1 and FIG. 2, the coins sent from the rotary disc 2 are guided by the coin conveying belt 3 to the guide passage portion 4.
Be transported to. The guide passage portion 4 includes a guide plate 5 and a coin guide member 6, and the coin guide member 6 includes an inclined surface 7 that rises in the coin advancing direction, a horizontal surface 8 that is continuous with the inclined surface 7, a side surface 9, and a side surface 9. It has a continuous curved surface 10. The side surface 9 is arranged in parallel with the guide plate 5 at an interval equal to the outer diameter of the set coin. Further, the coin sorting device 31 according to the embodiment of the present invention has a coin passage restricting member 32 instead of the conventional coin passage restricting arm, and the coin passage restricting member 32 can rotate the roller 33 at one end. And an arm 35 that is pivotally supported around the shaft 34 at the other end. The arm 35 is biased in the counterclockwise direction in FIG. 1 by the spring 36. When the arm 35 does not come into contact with the coin, the stopper pin 37 causes the peripheral surface of the roller 33 and the linear portion 15 of the guide plate 5 to move. The position is regulated so that the interval is the same as the outer diameter of the set coin and the roller 33 is on the inclined surface 7. As shown in FIG. 2, the distance between the lower surface of the roller 33 and the inclined surface 7 is set to be smaller than the thickness of the coin having the smallest thickness.

When the set coin or the small-sized coin sent from the rotary disc 2 comes into contact with the roller 33, the roller 33 based on the spring 36
The counterclockwise urging force of the guide plate 5 pushes the guide plate 5 toward the guide plate 5, and the guide plate 5 does not ride on the inclined surface 7.
Is conveyed by the coin conveying belt 3 between the linear portion 15 and the side surface 9 of the coin guide member 6, and is guided to the set coin accommodating portion or the small diameter coin accommodating portion, respectively.

On the other hand, in the large-diameter coin sent from the rotary disc 2, the distance between the roller 33 and the straight line portion 15 is set to be equal to the outer diameter of the set coin, so one side is in contact with the guide plate 5 and the other side is in contact. The roller 33 in FIG.
Swing clockwise about axis 34. Therefore, with one side of the large-diameter coin in contact with the straight portion 15 of the guide plate 5,
On the other side, it rides on the inclined surface 7 and in an inclined state, it is conveyed by the coin conveyor belt 3 over the horizontal surface 8 over the curved surface 10 to the large-diameter coin outlet 20. When the large-sized coin has finished passing through the roller 33, the roller 33 immediately returns to the original position before the large-sized coin has passed, that is, the tip of the roller 33 is on the same line as the side surface 9 due to the elastic force of the spring 36. Therefore, even when the set coin or the small coin is continuously conveyed immediately after the large coin, the roller 33 already returned to the initial position pushes the coin toward the guide plate 5. Done again, roller 33
Since the gap between the inclined surface 7 and the inclined surface 7 is set to be smaller than the thickness of the coin having the smallest thickness, the coin does not enter between the roller 33 and the inclined surface 7 and can ride on the inclined surface 7. This prevents the coins from being mistakenly conveyed to the large-diameter coin discharge port 20.

Further, in this embodiment, the guide plate 5 on the horizontal plane 8 is used.
A projecting portion 38 is formed in a portion from before the end point to the curved surface 10, and even when the difference in outer diameter between the set coin and the large-diameter coin is small, one end of the protruding portion 38 has an inclined surface 7 Get on
Furthermore, the large-diameter coin that is carried while being supported by the horizontal surface 8 is configured so that the portion on which the large-diameter coin rides is large so that it does not slip off the horizontal surface 8. Here, the lower surface of the protruding portion 38 is set so that the distance from the bottom surface of the guide passage portion 4 is equal to or larger than the thickest coin. Further, a coin guide member 39 having vertical walls is provided on the horizontal side of the horizontal plane 8, and a large-sized coin carried on one side of the horizontal plane 8 and conveyed is accidentally jumped out of the coin guide member 6. To prevent that.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and those modifications are also included in the scope of the present invention. Needless to say.

For example, in the above-described embodiment, the arm 35 is brought into contact with the stopper pin 37 so that the peripheral surface of the roller 33 and the linear portion of the guide plate 5 can be in contact with the coins.
The position is regulated so that the interval with 15 is the same as the outer diameter of the set coin, but the interval may be set smaller than the outer diameter of the set coin, and further, the coin to be selected. It may be set smaller than the minimum value of the outer diameter of. When set in this way, coins other than large-diameter coins can be reliably conveyed by the rollers 33 along the linear portion 15 of the guide plate 5. However, if it is set to be much smaller than the minimum outer diameter of coins to be sorted, the resistance will increase when a large coin passes, so this interval is less than or equal to the outer diameter of the set coin and the outer diameter of the coin to be sorted. It is desirable to set the range to be slightly smaller than the minimum value of.

Further, in the above embodiment, the roller 33 is provided at one end of the arm 35, but a protrusion is provided at one end of the arm 35, whereby when a coin having an outer diameter larger than the set coin is guided. When the arm 35 swings to the side opposite to the guide plate 5 and, on the other hand, the set coin or the small-sized coin is guided, it suffices that it can be pushed in the direction of the guide plate 5, and the roller 33 Alternatively, one end of the arm 35 may be provided with a protrusion having a generally smooth peripheral surface or a protrusion having a smooth peripheral surface on the side where the coin is guided.

Further, in the above-described embodiment, one coin passage restricting member is provided, and the roller 33 supported at one end thereof is arranged along the inclined surface as shown in FIG. It is also possible to arrange a plurality of rollers in parallel and to support the rollers at one end thereof in front of the inclined surface (on the left side of the roller shown in FIG. 2).

Further, in the above-described embodiment, the lower surface of the protruding portion 38 is set so that the gap between the lower surface of the protruding portion 38 and the bottom surface of the guide passage portion 4 is equal to or larger than the thickest coin. The space between the bottom surface of the portion 4 and the bottom surface may be larger than the thicknesses of the set coins and the small-diameter coins, and the coin guide member can be configured such that the space can be adjusted according to the coins to be taken out.

〔The invention's effect〕

The coin passage restricting member in the effect sorting device of the present invention is
Unlike a conventional coin passage restriction arm, it does not come into contact with a large-diameter coin in a straight line portion, so that it immediately returns to its original position after passing a large-diameter coin. Therefore, even when the set coin or the small coin is continuously conveyed immediately after the large coin, the set coin or the small coin can be pushed out to the guide plate side, and the set coin or the small coin is inclined. It is possible to prevent the vehicle from being ridden on the surface and being accidentally guided to the large-diameter coin outlet as it is. Further, if a plurality of coin passage restricting members are provided, the force for pushing the set coin or the small-diameter coin to the guide plate side becomes large, and the conveying direction of the coin is restricted in a wide range, so that the above effect can be more reliably achieved. obtain.
