Using a feeding device that feeds out coins one by one, the coins are taken into the linear conveyance path of the sorting device, and then the coins are sorted through sorting holes (also called slits) arranged in a straight line in the order of the small diameter of the coins provided in the conveyance path. ) to sort coins by diameter size.

[Problem to be solved by the invention]

In the prior art described above, the sorting holes corresponding to the outer shape of the coins are arranged in a straight line, resulting in a device that is quite elongated in the straight direction. Further, since the outlet of the feeding device faces in the tangential direction of the hopper and the linear sorting device is simply connected to this outlet, it is difficult to miniaturize the device in this respect as well.

In order for the coins to pass through the sorting hole at the correct position, a coin rail is required to guide the coins and convey them using a belt, and it is difficult for the coins to be conveyed while always wandering around the coin rail.

The gates are respectively provided in the coins, and the gates of the corresponding denominations are opened by a coin receiving gate solenoid in response to a signal from an electronic coin validation sensor.

In the coin sorting device according to invention 10, in the invention 1, the feeding mechanism includes a hopper, a feeding disk that is arranged under the hopper, is rotationally driven, and has a feeding hole, and a fixed side that is in contact with the bottom of the feeding disk. a delivery plate provided with a hole; the feeding disk rotates synchronously with the taking-in disk on the same axis, close to the same axis, or tilted; and the feeding hole has a size that can take in coins with a maximum diameter. The passing hole is located at the taking-in position and has a position for passing the coin in the feeding hole and delivering it to the taking-in hole.

[Effect]

In invention 1, the coin taken into the take-in hole is pushed by the rear contour of the take-in hole while being in contact with the outer periphery of the fan-shaped take-in hole due to centrifugal force, and is conveyed on the conveying face plate. At this time, since the outer periphery coincides with that for conveyance, the coin is conveyed while being inscribed for virtual conveyance. In addition, the corner formed between the rear contour and the outer periphery is made small so that even a coin with the smallest diameter can be pressed by the rear contour and simultaneously contact the outer periphery, so that coins can be conveyed while being inscribed in the same manner. will be done.

If the coin is larger than the corresponding sorting hole, it will pass through, and since the coin has a width slightly larger than the diameter of the coin in the corresponding sorting hole, it will fall through the sorting hole and be placed in a container for each denomination. Since the sorting holes are arranged in order from the smallest diameter of the coin to the largest, the coins are eventually sorted by diameter size. Since the coins are sorted by the width of the sorting hole, the length in the transport direction only needs to be larger than the corresponding coin diameter, and may be longer in the circumferential direction.

In invention 2, the mixed coins thrown into the hopper fit into the payout hole of the payout disk, and the coins in the payout hole at a position on the bottom plate do not fall and rotate as they are.

When the payout hole of the payout disk and the take-in hole of the take-in disk, which rotate synchronously, reach the take-in position and overlap, the coin falls from the pay-out hole into the take-in hole and is taken in.

The coins taken into the receiving hole are then sorted as described in the detailed description of the invention above.

In invention 3 or 4, foreign objects or counterfeit money that are smaller (larger) than the minimum diameter of the target coin are taken out from the return hole.

In invention 5, the pinch roller pushes the coin through the corresponding sorting hole, causing the coin to fall quickly in addition to falling under its own weight.

When the pinch roller makes contact with the coin and rolls, the coin is mechanically directed toward the fan-shaped outer periphery of the take-in hole by making the direction of rolling to be approximately tangential to the conveyance direction or outward from this direction. Since the coins are subjected to force, the coins are reliably inscribed on the outer periphery, that is, for transportation, even by a force other than the centrifugal force, and the predetermined sorting in the sorting holes can be performed more correctly.

If the pinch roller is located ahead of the sorting hole in the transport direction,
There is a risk that the tip of the coin that is supposed to pass through the sorting hole will be pushed diagonally and get caught in the sorting hole, but since the coin is located at a distance smaller than the radius of the corresponding coin from the rear outline of the sorting hole, such a catch may occur. It's fleeting.

In invention 6, the rear contour of the intake hole, which is inclined in the conveying direction from the outer circumferential side to the inner circumferential side, has a component force that directs the coins outward from the conveying connection, so that the coins can correctly pass through the sorting hole. This eliminates erroneous selection. By using a pinch roller, it can be quickly dropped through the sorting hole.

In invention 7, the coins conveyed through the intake hole are maintained horizontally by the conveying face plate on the lower surface and the presser plate on the upper surface, pass through the sorting hole horizontally, and are correctly sorted and fall into the corresponding sorting hole.

In invention 8, since it has a presser plate and a pinch roller, it has the same effect as inventions 5 and 7, and the coin is conveyed horizontally by the presser plate, and is actively inscribed for conveyance by the pinch roller,
In addition, in the corresponding sorting hole, it quickly falls down due to its own weight and the force of the pinch roller and is sorted.

With this configuration, since there is a presser clamp, the pinch roller can be placed anywhere inside the sorting hole, and the length of the sorting hole in the conveying direction is increased and the intake disk is rotated at high speed, allowing processing to be carried out. Speed can be increased.

In invention 9, the electronic coin validation sensor detects the denomination, the corresponding gate is opened by the coin acceptance solenoid, and coin sorting is performed.

In invention 10, when the coin in the dispensing hole of the dispensing disk coaxially with, close to coaxially with, or tilted to the dispensing disk comes to the dispensing position, the coin passes through the passing hole of the delivery disk to the dispensing hole of the dispensing disk. be taken in. The delivery disk can also have the function of the holding plate of the seventh invention, and can also be provided with pinch rollers.

FIG. 9 is a plan view of the screening hole of Example 2, and FIG.
The figure is a plan view of the intake hole of the third embodiment, and FIG. 11 is an exploded perspective view of the sorting mechanism of the fourth embodiment.

FIG. 1 to FIG. 8 showing Example 1 relate to Inventions 1 to 5. The lower end of a hopper 1 into which multiple types of coins are mixed and thrown in at once is rotatably driven by a drive machine 2.
A bottom plate on which a feeding disk 4 is located, which has a plurality of fan-shaped (or circular) feeding holes 3 large enough to take in the coins with the largest diameter among the coins to be sorted, and below which is provided an arc-shaped missing portion 5a. 5 is provided on the fixed side to constitute a feeding mechanism 6.

Fan-shaped intake hole 1 large enough to accept coins of maximum diameter
A plurality of intake disks 12 are disposed so as to partially overlap the feed disk 4 and adjacent to the missing portion 5a of the bottom plate 5. - Each one of the sets of synchronizing gears 7a and 7b meshes with the tooth profile 12g of the intake disc 12 and the tooth profile 4g of the delivery disc 4, so that when the drive machine 2 is rotated, the delivery disc 4 and It rotates in synchronization with the intake disk 12 as shown by the arrow. Note that synchronization means that the output hole 3 and the intake hole 11 match at the intake position Wps, and if the numbers of both holes are equal, the rotational speeds will also be different. In addition, the synchronization gears 7a, 7b and the tooth profile 4
Instead of using gear g, a gear may be fixed to the central solid lower end of the feed-out disk 4 and meshed with the tooth profile 12g of the intake disk 12. At this time, although the rotational speed is different, feeding hole 3 and intake hole 1
The number of 1's may be changed to synchronize at the capture position.

4g may be used instead of 12g.

From FIG. 3 to FIG. 5, the feeding operation situation (p, , Pz , P3 ) in which the coin C in the feeding hole 3 is taken into the feeding hole 11 in the feeding disk 4 and the taking-in disk 12 that rotate synchronously is shown. In the state of the linear take-in position P3 connecting the rotation centers of both the disks 4.12, the feeding hole 3 and the take-in hole 11 overlap to the maximum, and the coin C is taken into the take-in hole 11. It will be done. Note that the bottom plate 5 holds the coins C in the payout hole 3 in the hopper 1 at a location other than the receiving disk 12.

Note that, instead of the feeding mechanism 6, a known feeding mechanism shown in the prior art may be combined.

Next, a mechanism for sorting the coins taken into the taking-in hole 11 of the taking-in disk 12 according to their diameter will be explained. The coin sorting device is composed of the feeding mechanism 6, the taking-in disk 12, and a conveying face plate 14 having sorting holes 13 (L3a-13f) corresponding to the diameter of the coins.

As already explained, the intake hole 11 of the intake disk 12 is fan-shaped and is large enough to accept coins of the maximum diameter. The fan-shaped outer periphery 11a of the intake hole 11 coincides with a circle concentric with the rotation center of the mounting disk 12 (hereinafter referred to as a conveyance circle 15). Rear contour 1 of the intake hole 11 in the conveyance direction
The corner 11c formed between 1b and the outer periphery 11a is made small enough to allow a coin of the smallest diameter to contact the outer periphery 11a and the rear contour 11b at the same time. For example, if corner 11c is an arc, it should be an arc smaller than the radius of the coin with the smallest diameter (corner 11c in Figure 10).
1c etc.).

As a result, as shown in FIG.
It is conveyed on the conveyance face plate 14 while contacting with. That is, all coins are conveyed while being inscribed in the conveyance circle 15.

On the other hand, the conveyance face plate 140 sorting holes 13a to 13f each have a diameter slightly larger than the diameter of the corresponding coin,
The coins are inscribed in the conveyance circle 15 and arranged in order from the smallest diameter to the largest coin diameter. Here, a slightly larger diameter is synonymous with being larger than the diameter of the corresponding coin and smaller than the diameter of the next largest coin. For example, the reference outer diameter of ¥5 is 22 meters, and the reference outer diameter of the next size ¥100 is 22.6 m, so the diameter corresponding to ¥5 is approximately 22.2+n, which is slightly larger than 22-u. Good.

However, the selection hole is not necessarily circular, and Example 2 shown in FIG.
Like the sorting holes 33 (33a to 33f), the length in the conveying direction is sufficiently larger than the diameter of the corresponding coin, and the width (equivalent to the diameter of 13) is slightly larger than the diameter of the coin. It may be something that is inscribed.

Sorting holes I3 or 33 arranged in such order of size
The coins that are taken into the intake hole 11 of the intake disk 12 and are conveyed inscribed in the conveyor 15 fall from the corresponding sorting hole I3 or 33 and are sorted by denomination. It fits into the container 16.

Figures 6 and 7 show situations Q and Q in which a coin (¥10) C falls into the corresponding sorting hole 13e, and Figure 7 shows that the coin (¥500) c is larger than the sorting hole 13e. Shows the situation when passing through a lever hole.

As related to Invention 3 or 4, Embodiment 1 includes a return hole smaller than 13a behind the sorting hole 13a (or 33a) in the conveyance direction for the minimum diameter of coins to be sorted (for example, the diameter of ¥1). 17. or by providing a return hole 17L larger than the sorting hole 13f (or 33f) with the largest diameter (for example, 500 yen) to sort defective coins by diameter. A return hole may be provided at a location where the difference in diameter between the diameter layers of normal coins is large.

According to the fifth aspect of the present invention, in the first embodiment, a pinch roller 19 biased from above by a spring 18 is attached to a fixed plate 20 corresponding to each sorting hole 13, and the coins fall by their own weight in the corresponding sorting hole 13. In addition to doing so, quickly drop the coin. This is also utilized in the second embodiment shown in FIG.

The position of the pinch roller 19 is such that the contact surface with the coin is in the sorting hole 13.
, and in the case of Fig. 9, the sorting hole 33
The position is a distance smaller than the radius of the corresponding coin from the rear contour 33X.

If the coin is located ahead of this position in the transport direction, there is a risk that the tip of the coin to be passed through the sorting hole 13 (or 33) will be pushed and become diagonal and get caught in the sorting hole.

The direction in which the pinch rollers 19 roll is approximately tangential to the conveyance direction or outward from this direction. As shown in state Qz in FIG. 6, the pinch roller 19 rolled over the coin Ce has width and friction, so the movement of the coin is dynamically restricted in the rolling direction F of the pinch roller. As a result, the tangential direction of the contact point between the outer periphery 11a of the intake hole 11 and the coin Ce and F are at an angle θ
occurs, and even if the coin is away from the outer periphery 11a, the coin tries to contact the outer periphery 11a, and the coin is actively inscribed in the above-mentioned conveying inside 15, and the centrifugal force is added to the sorting hole 1.
3 (or 33) in the correct position.

Even if the rolling direction F of the pinch roller is tangential to the transport direction, θ will occur depending on the diameter of the coin, so it may be directed inward in the tangential direction within the range of θ, and in that sense, it is called the ``tangent direction.''
That's what it means. Note that instead of the pinch roller, a temporary spring or the like may be used to push the coin with a tip material that has a low friction coefficient and wear to help the coin fall, but there is no force to inscribe the coin within the conveyance.

Now, the description has been given from FIGS. 1 to 8 showing the first embodiment with a part of the description of the screening hole 33 in FIG. 9 showing the second embodiment.

Sorting holes 33 (33a to 33f) of the conveyance face plate 34 in FIG. 9
As mentioned above, since it is inscribed in the conveying inner part 15 and is elongated in the conveying direction, when the coin falls from the taking-in hole 11 to the sorting hole 33 (also when using the pinch roller 19), the horizontal direction velocity due to inertia is increased. to overcome this and prevent accidental passing. Therefore, it is suitable for high-speed processing.

If the drive unit 2 is a step motor, the screening holes may be circular even at high speeds, and the screening holes 13 are close to each other so that the entire inside of the conveyor, etc., has a small diameter.

Figure 10 shows the intake circle +7i4 with the intake hole 41 of Embodiment 3.

1b, the inner circumference side is inclined by θ2 in the conveying direction than the outer circumference side, so the force F2 pushing the coin C actively pushes the coin C toward the outer circumference 41.
a, that is, inside the conveyance, to ensure sorting.

Inventions 7 and 8 will be explained with reference to FIGS. 1 and 7. A presser plate 50, indicated by the dashed line in FIG. 7, is attached to the fixed side on the intake disk 12 with a gap therebetween. Presser plate 50
It is sufficient to cover the upper part of each sorting hole 13 (or 33), but a single plate having a shape similar to the fixed plate 20 may also be used. When the pinch roller 19 is provided, a hole 51 for that purpose is provided.

According to such a structure, the intake disk 12 rotates between the holding plate 50 and the conveyance face plate 14, and the intake hole 11
The coins taken in by the pinch roller 19 are kept horizontal between them, and are not caught diagonally in the sorting hole 13.
When using the pinch roller 1 to quickly drop the material into the sorting hole,
There is also a degree of freedom in that the position of the contact surface between the coin and the coin can be any position within the range inside the sorting hole 13 (or 33).

The sorting mechanism of Example 4 shown in FIG. 11 is related to invention 9,
Components with the same reference numerals as in FIG. 1 have roughly the same functions, and some explanations will be omitted. In the figure, an electronic coin validation sensor 61 is provided on the conveyance face plate 64 to detect the denomination passing therethrough. The gates 62 (62a to 62f) for each denomination do not have size requirements like the aforementioned sorting hole 11, and the electronic coin validation sensor 61

make it work.

Invention 10 will be explained with reference to FIG.

The delivery inner attack 4 is placed coaxially (or close to the cross-axis or slightly tilted) on the intake inner attack 12. A transfer plate with approximately the same diameter as both discs is installed on the fixed side between the two inner plates, and a passage hole is provided at the receiving position P of this transfer plate through which a coin of the maximum diameter can pass (the above-mentioned one that tilts the shaft) (A thin position on the delivery plate is best). The drive machine 2 is disposed under the conveying face plate 14 to rotate the intake inlet 4 and the hopper 1 is disposed above the delivery disk 4. Fixed plate 20, bottom plate 5, synchronization gears 7a, 7b,
Do not use tooth profiles 4g and 12g. If the pinch roller 19 is required, its support column may be made horizontal, the spring 18 may be a leaf spring, and a recess may be provided on the back surface of the delivery plate and incorporated therein. Further, the feeding disk 4 and the receiving inner roller 12 may be driven at different rotational speeds, and the wall of the passage hole in the transport direction is preferably made oblique to match the direction in which coins fall from the feeding hole.

The coins in the feed hole 4 are taken into the take-in hole through the passage hole, and then the same operation as in the implementation 1 is performed. In this structure, the feeding mechanism completely overlaps the taking-in disk coaxially, making the device even more compact, and the transfer plate can also act as the holding plate of the seventh or eighth invention.

〔Effect of the invention〕

In the coin sorting devices of Inventions 1 to 8, the outer periphery of a coin taking-in hole provided in a rotating taking-in disk is inscribed in a conveying circle, and Since the sorting holes are inscribed in the conveying circle and arranged in the order of the diameter of the coins, the coins are inscribed in the conveying circle and sorted from the sorting holes in order of small diameter by centrifugal force, and the coins are sorted from the sorting holes in order of small diameter. The coins are arranged in a circle rather than in a straight line, making the device more compact, and the coins are conveyed while being reliably inscribed in the conveyor circle without using the conventional coin rail, allowing reliable sorting without missorting. effective.

Invention 2 combines a feeding mechanism that synchronously rotates a feeding disk with a feeding hole that partially overlaps the feeding disk and takes coins from the feeding hole to the feeding hole at the feeding position. The insertion disk and the feeding mechanism are arranged so that their circles overlap, which has the effect of making the device more compact.

Invention 3 or 4 provides a return hole after the sorting hole or in the stack, so that foreign objects smaller or larger than the target coin, counterfeit money, etc. can be sorted out.

In invention 5, the pinch roller helps the coins fall into the sorting hole by their own weight, thereby increasing the speed of sorting, and by determining the rolling direction, the effect of centrifugal force on the coins being inscribed in the conveying circle is increased, making the sorting more efficient. Assure.

Invention 6 makes sorting more reliable by inclining the rear contour of the intake hole to generate a component of the conveying force that presses against the conveying circle.

Invention 7 or 8 employs a holding plate, and the taking-in disk rotates so as to be squeezed between the holding plate and the conveying face plate, so that the coins in the mounting hole always remain horizontal and do not get caught in the sorting hole, making it smooth. This has the effect of making it suitable for high-speed sorting.

Invention 9 allows an electronic coin validation sensor to perform denomination discrimination, and has the effect that the electronic coin sorting device is configured in a circular shape, making it easier to maintain the machining dimensional accuracy of the sorting holes and the like.

Invention 10 has the effect that the feeding disk and the taking-in disk are arranged close to the same axis, making it even more compact.
