Next, the operation of this embodiment will be described.

Coins in a mixed state of multiple denominations to be sorted are thrown in through the upper opening 11 of the hopper 3 and stored on the conveyor 4 at the bottom of the hopper 3.

When the motor 111 is driven, the conveyor belt 34, the reverse rotation roller 36, and the holding belt 83 of the conveyor 4 are rotated in conjunction with each other.

As the first conveyor area 34a of the conveyor 4 moves in the coin sending direction F1, coins in the hopper 3 are sent out toward the obliquely upper outlet 21 and the gate section 5 causes the coins in the radial and thickness directions. Passage 6
Sent out to

When the coin passes through the gate portion 5, the coin is reduced to a single coin in the radial direction between the two regulating walls 22, and when the coin passes below the reverse roller 36, the coin directly contacts the conveyor 4. The coins on the coins to be returned are returned into the hopper 3 and made into one piece in the coin thickness direction, so that the coins are made one piece in the radial direction and the thickness direction and sent out to the passage portion 6.

Here, as shown in FIG. 11 (in the figure, S indicates a horizontal plane; the same applies hereinafter), when the conveyor zone 34a moves, a standing rotating coin C leaning against the side wall of the hopper 3 is generated. When the standing rotating coin C rotates rearward (to the left) in the coin delivery direction of the hopper 3 due to the inclination of the conveyor area 34a, the coin C is moved to the conveyor area 34a by the rear side wall portion 17b as shown in FIG. While the direction is changed to the center in the width direction, the coin C is temporarily lifted on the coin loading upper surface portion 19, and the moving force from the conveyor area 34a is cut off.
As shown in FIG. 13, the coin C is
Is changed so as to face the width direction of the conveyor area 34a, and the coin C slides down on the coin loading upper surface portion 19, falls on the conveyor area 34a, and is sent out by the conveyor area 34a.

The coins fed into the passage 6 through the gate 5 are sandwiched between the conveyor belt 34 and the pressing rollers 43 and 44, and come into contact with the guide edge 41a of the coin reference edge member 41. It is moved along the edge 41b.

In this passage section 6, intermittent coin sending means
By 45, coins sent from the gate unit 5 are spaced. That is, when coins are sent out through the gate portion 5 into the passage portion 6 while the lever portion 50 of the coin locking member 46 is being lowered toward the conveyor 4 by the bias of the spring 54, FIG. As shown in FIG. 17 (a), coins C (1
A), the coin C (1B) sent to one side in the width direction of the passage also comes into contact with the lever portion 50 and is stopped.

Then, at a predetermined pitch synchronized with the coin feeding speed of the conveyor 4, the cam 56 is moved to the receiving plate portion 53 of the coin locking member 46.
Is pressed downward, and as shown in FIG.
Is raised to a height position larger than the coin thickness. Therefore, as shown in FIG. 14 and FIG.
The suspension of the coin C (1A) that has been in contact with
As shown in (1C), it is sent downstream through the lower side of the lever unit 50.

Further, since the rising period of the lever portion 50 is set to the coin sending distance of the conveyor 4 corresponding to the distance smaller than the coin diameter, as shown in FIG. 15 and FIG. Before the coin C (1D) passes under the lever portion 50, the lever portion 50 descends and comes into contact with the upper surface of the coin C (1D). Even if the lever 50 contacts the upper surface of the coin C (1D), the frictional resistance between the transport belt 34 and the coin C (1D) is greater than the frictional resistance between the lever 50 and the coin C (1D). Since it is large, the coin C (1D) is sent out as it is.

Then, as shown in FIGS. 16 and 17 (e), when the coin C (1E) passes the position of the lever portion 50,
Since the lever portion 50 is located closer to the other side than the center in the width direction of the passage, the coin C (1E) and the following coin C (2B) fall between the peripheral edge and the other side, and the subsequent coin C (2B) Is stopped.

Therefore, only the preceding coin C (1E) is sent to the downstream side, and the coin C (1F) is clamped between the transport belt 34 and the clamping belt 83 by the reverse transport section 7.

Thus, the coin C is intermittently stopped,
As shown in FIG. 17 (f), a predetermined distance T is provided between the preceding coin C (1F) and the following coin (2B).
When the lever is opened, the lever 50 rises and the following coin C
(2B) is sent out.

In the passage 6, the detecting means 61 detects the denomination of the coin intermittently transmitted through the intermittent coin transmitting means 45. That is, as shown in FIG. 18, the coin C intermittently transmitted through the coin
Of the coin comes into contact with the guide edge 41a of the coin reference edge member 41 and is conveyed along the reference edge 41b. At this time, the other edge of the coin C comes into contact with the coin detection pin 62, and the coin detection pin 62
Is rotated counterclockwise in the figure about the central axis 63 as a fulcrum.

The reason why the coin detection pin 62 is most rotated when the coin C passes is that the coin C whose peripheral edge contacts one side of the reference edge 41b.
The part located on the other side of the other side of the periphery of the coin detection pin 62
And corresponds to the diameter of the coin C with reference to the reference edge 41b. Therefore, as shown in FIG. 19, the rotation angle α1 of the coin detection pin 62 is small in the case of the small-diameter coin C1, and the rotation angle α2 of the coin detection pin 62 is large in the case of the large-diameter coin C2. .

The rotation angle of the coin detecting pin 62 is detected by a potentiometer 65, and the detected rotation angle is checked against a predetermined rotation angle for each denomination to determine the denomination. You.

In the passage section 6, when a batch signal or the like is input, the feeding of coins is stopped by the stopping means 71. That is, as shown in FIG.
When the denomination of coin C passing by rotating 62 is determined,
If the denomination of the coin C is counted by a predetermined number, a batch signal is issued, the solenoid 76 of the stopping means 71 is turned on,
The lock lever 72 rotates counterclockwise in the drawing, and the locking portion 73 of the lever portion 74 of the lock lever 72 engages with the coin detection pin 62 that returns to the home position. Therefore, intermittent coin sending means
Even if the other edge of the subsequent coin C intermittently delivered from 45 contacts the coin detection pin 62, the coin detection pin 62 does not rotate, and the coin C is transmitted to the coin reference edge member 41 and the coin detection pin 62. Stopped in contact. Even after the coin C is stopped, the coin C being conveyed downstream of the coin detection pin 62 is conveyed as it is to the coin sorting passage portion 8 through the passage portion 6 and the reversing passage portion 7, and the coin sorting passage. After a predetermined time required for completing the classification in the part 8, the motor 111 is stopped,
Thereafter, processing such as taking out the coin C from the box 101 of the coin sorting and storing section 9 is performed.

When the coins conveyed in the passage 6 reach the reversing conveyance section 7, the coins are held between the conveyance belt 34 and the holding belt 83, and the moving direction of the coins is the coin sending direction F1.
The coin is then reversed in the coin sorting and conveying direction F2 along the coin sorting passage 8 and fed into the coin sorting passage 8.

The coins fed into the coin sorting passage portion 8 through the reversing conveyance portion 7 are sandwiched between the upper surface of the sorting passage plate 91 and the second conveyor area 34b of the conveyor belt 34, and the coin reference The coin 41 is conveyed along the reference edge 95b in contact with the guide edge 95a of the coin reference edge member 95 projecting more toward the center of the passage than the reference edge 41b of the edge member 41. At this time, the reference edge 95b
Since the downstream side is inclined about 0.5 ° toward the center in the width direction of the coin with respect to the coin sorting and conveying direction F2 in which the second conveyor area 34b of the conveyor belt 34 moves, the second conveyor area 34b The conveyed coin is conveyed while maintaining a contact state with the reference edge 95b.

When a coin conveyed by contacting one side of the periphery with the reference edge 95b of the coin reference edge member 95 passes over the classification hole 96, a coin larger in diameter than the corresponding denomination of the classification hole 96 is The coins of the corresponding denomination are passed on the other side by the pressing roller 97 on both sides of the sorting hole 96.
It is dropped into the coin 96 and is stored in a denomination storing section 102 of a box 101 disposed below the coin sorting passage section 8.

When coins are jammed in the coin sorting passage 8 or during maintenance and inspection, by removing the lock lever 97, as shown by a two-dot chain line in FIG.
By rotating the sorting passage plate 91 downward with the 92 as a fulcrum (which can be performed with the coin sorting storage section 9 removed), it is possible to clear a jam of coins and perform maintenance and inspection.

In the coin sorter configured as described above, the coin sorting passage 8 is disposed below the coin storage 2, and the conveyor 4 is arranged between the coin storage 2 and the coin sorting passage 8. Because of this, it is possible to reduce the size of the coin sorting machine in the horizontal direction and reduce the installation space for the coin sorting machine. In addition, the delivery of coins from the coin storage unit 2 and the transport of coins in the coin sorting passage 8 are performed by one conveyor 4. In addition, the structure can be simplified and the cost can be reduced.

Further, even if the standing area rotating coins which lean on the side wall 15 of the hopper 3 due to the movement of the conveyor area 34a are generated, the coins are rotated to the rear side of the hopper 3 in the coin sending direction. Then, the coins are changed in direction toward the center in the width direction of the conveyor area 34a by the rear side wall portion 17b and the arc guide wall portion 18, and the coins are temporarily lifted on the coin mounting upper surface portion 19 and moved from the conveyor area 34a. When the force is cut off, the coin slides down on the coin loading upper surface portion 19 and is surely dropped onto the upper surface of the conveyor area 34a and is sent out, so that it is possible to prevent the coin from remaining in the hopper 3.

Even if the coins are sent out from the coin storage section 2 and the coins are conveyed in the coin sorting passage section 8 by one conveyor 4, the intermittent coin sending means 45 provided in the passage section 6 is provided.
Thus, the coins are spaced apart from each other, so that erroneous sorting by the detecting means 61 and erroneous sorting in the coin sorting passage section 8 can be prevented. In addition, the intermittent coin sending means 45 makes the conveyor 4
Since the interval between coins can be spaced above, the denomination of coins can be detected at an earlier point in time, so that the coin sorter can be downsized and the processing capacity can be increased.

In the passage section 6, the denominations of the coins spaced by the intermittent coin sending means 45 can be reliably detected by the detecting means 61, and moreover, on the conveyor 4 near the downstream position of the intermittent coin sending means 45. By performing the denomination detection, it is possible to contribute to miniaturization of the coin sorter and improvement of the processing capacity.

Further, in the passage section 6, the coins spaced by the intermittent coin sending means 45 can be reliably stopped by the stopping means 71 via the coin detecting pin 62 of the detecting means 61,
In addition, by stopping the coin on the conveyor 4 near the downstream position of the intermittent coin sending means 45 via the coin detecting pin 62 of the detecting means 61, it is possible to contribute to downsizing of the coin sorting machine and improvement in processing capacity.

According to the coin storing and feeding device of the present invention, even if a standing rotating coin leans against the side wall of the hopper due to the movement of the conveyor area, the standing rotating coin is used as the coin of the hopper. When the coin is rotated to the rear side in the feeding direction, the standing rotating coin is changed in direction by the rear side wall toward the center in the width direction of the conveyor area, and the standing rotating coin is temporarily lifted on the coin loading upper surface to convey the coin. When the moving force from the area is cut off, the coin slides down on the coin loading upper surface portion and is reliably fallen onto the upper surface of the conveyor area and is sent out, so that it is possible to prevent the coin from remaining in the hopper.

According to the coin storing and feeding device of the second aspect, in addition to the effect of the coin storing and feeding device of the first aspect,
The arc guide wall can reliably change the direction of the upright rotating coin toward the center in the width direction of the conveyor area, and the coin can be reliably knocked down in cooperation with the coin loading upper surface provided below the arc guide wall. Can be.
