DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin separating apparatus for separating coins from coins such as numbered tickets.

[0002]

2. Description of the Related Art Heretofore, as this type of coin separating apparatus, for example, there is a coin separating apparatus for separating coins from rearranging tickets such as buses. That is, as shown in FIG. 6, a pair of separation rollers 52 and 53 that are inclined with respect to the horizontal direction are rotatably provided in the coin separation device 51.
Both separation rollers 52 and 53 can be approached and separated.
The two separation rollers 52, 53 are located at the approach position (the position indicated by the solid line in FIG. 6).
The contact is made so that there is no gap between them, and only the numbered ticket 54 can pass. Further, the separation rollers 52 and 53 are arranged at the separated position (the position indicated by the two-dot chain line in FIG. 6).
4 and the coin 55 can pass through. A coin identification sensor 56 for identifying the type of the coin 55 is provided below each of the separation rollers 52 and 53. At the center of the coin identification sensor 56, a detection passage 56a through which the coin 55 passes is formed.

When the numbered ticket 54 and the coin 55 drop onto the upper part of the separation rollers 52 and 53, the numbered ticket 54 passes between the separation rollers 52 and 53. On the other hand, the coin 55 does not pass between the separation rollers 52 and 53, but rolls downward along the passage portion 57 surrounded by the outer peripheral surface between the separation rollers 52 and 53 and moves toward the coin identification sensor 56. Thereby, the numbered ticket 54 and the coin 55 are separated. Thereafter, the separated coin 55 is supplied to the detection path 56 of the coin identification sensor 56.
By passing through a, the type of the coin 55 is identified. When the coin 55 or the numbered ticket 54 is caught between the separation rollers 52 and 53 and jammed, a jam detection sensor (not shown) detects the jam and the separation roller 5
2, 53 are separated. As a result, the jammed coin or numbered ticket 54 falls down, thereby eliminating the jam.

[0004]

However, in the above-described coin separating apparatus 51, when a large number of coins 55 are rolling in the passage portion 57 when the two separating rollers 52, 53 are separated from each other, the coins are separated in the vertical direction. Do not fall straight down. That is, since the coin 55 has momentum in the rolling direction, it falls obliquely with respect to the vertical direction. For this reason, the coin may be put on the upper surface of the coin identification sensor 56 and block the detection passage 56a. Therefore, after the separation rollers 52 and 53 return to the approach position again from the separation position, the sorted coins 5
5 has a problem that the coin 55 cannot pass through the detection path 56a of the coin identification sensor 56 and cannot be identified.

Accordingly, an object of the present invention is to prevent a coin from being put on a coin identification sensor when the separation roller is separated.

[0006]

According to the first aspect of the present invention, a pair of separation rollers for separating a coin and a coin are provided so as to be able to approach and separate so as to be inclined with respect to the horizontal direction. A coin identification member for identifying the type of separated coin is provided below, and both separation rollers are approached when separating a coin from a coin, and when a ticket or coin is jammed in both separation rollers, both separation rollers are In the coin separating apparatus, the coin separating means is provided to prevent coins from being placed on the coin identifying member as the two separating rollers are separated from each other.

[0007] The invention according to claim 2 is characterized in that the coin removing means inclines the coin discriminating member with respect to the horizontal direction. The gist of the invention described in claim 3 is that the coin removing means is an interlocking mechanism for preventing coins from being placed on the coin identification member in conjunction with the separation of the two separation rollers. .

The invention according to a fourth aspect is characterized in that the interlocking mechanism tilts the coin identifying member with respect to the horizontal direction by its own weight.

A movable separation roller 18 is provided inside the support frame 17 so as to be inclined with respect to the horizontal direction, and both ends thereof are rotatably supported by both ends of the support frame 17. That is,
The axes of the separation rollers 15 and 18 are parallel to the inclination direction. And, with the movement of the movable frame 13,
The separation rollers 15 and 18 are adapted to approach or separate from each other. When the two separating rollers 15 and 18 are close to each other, there is a groove-shaped passage portion A surrounded by the outer peripheral surfaces of the respective separating rollers 15 and 18.

A plurality of grooves 19 are formed on the outer peripheral surfaces of the separation rollers 15 and 18 at predetermined intervals in the axial direction. Each of the separation rollers 15, 1 is formed by the groove 19.
The outer peripheral surface of 8 is formed in an uneven shape. Double separation roller 1
When 5,18 are approaching, both 15,18
Is set to 0 to 0.1 mm. One end of each of the separation rollers 15 and 18 is drivingly connected via a gear (not shown), so that the separation rollers 15 and 18 rotate inside them.

As shown in FIGS. 1 and 2, feed rollers 20, 21 have bearings 20a, 21a on the inner surfaces of the fixed and movable frames 12, 13 at the lower side of the separation rollers 15, 18 in the inclination direction. It is rotatably supported through. The two feed rollers 20 and 21 are separated from each other at a predetermined interval. And each feed roller 20, 21 is
One rotates inward and the other rotates outward. That is, both feed rollers 20, 21 rotate in directions opposite to each other.

As shown in FIGS. 2 and 3, a bracket 22 having a U-shape is fastened and fixed to the inner surface of the movable frame 13 below the separation rollers 15 and 18 by screws 23. A sensor holder 24 is provided inside the bracket 22, and a shaft 25 extends through the right end of the sensor holder 24. Then, both ends of the shaft 25 are penetrated and supported by both ends of the bracket 22 so that the sensor holder 24
Is rotatable about a coaxial 25.

As shown in FIGS. 3 and 4, a coin identification sensor 26 as a coin identification member is provided in a concave portion 24a formed on the upper surface of the sensor holder 24. A holding member 27 is fastened and fixed to the left side surface of the sensor holder 24 by a screw (not shown). A claw 27a is provided on the upper surface of the holding member 27 so as to protrude laterally. The claw 27a is locked on the upper surface of the coin identification sensor 26, so that the coin identification sensor 26 is held and held in the sensor holder 24. ing. At the center of the coin identification sensor 26, there is provided a detection passage 26a for passing coins, and a slit 24b is formed in the sensor holder 24 directly below the detection passage 26a. When the coin passes through the detection passage 26a, the type of the coin is identified.

As shown in FIGS. 3 and 5, an engagement pin 28 as an engagement member is protruded from the inner surface of the movable frame 13 at the right edge of the sensor holder 24.
A projection 24c (see FIG. 2) is integrally formed on one side of the sensor holder 24 below the engagement pin 28. A leaf spring 2 having a horizontal L-shape is provided on the left side surface of the projection 24c.
9 is fastened and fixed by mounting screws 30. The leaf spring 29 includes a base portion 29a extending vertically along the left side surface of the protrusion 24c, and an arm portion 29b bent at an obtuse angle with respect to the base portion 29a. The tip of the arm 29b is always pressed against the tip of the engaging pin 28 by its own elastic force. And FIG.
As shown by a two-dot chain line, the sensor holder 24 moves rightward as the two separating rollers 15 and 18 move away from each other, and the movable frame 13 moves rightward. In a state where the sensor holder 24 is in contact with the leaf spring 29, the sensor holder 24 rotates downward about the shaft 25 by its own weight. Accordingly, the rotation of the sensor holder 24 causes the upper surface of the coin identification sensor 26 to be inclined downward with respect to the horizontal direction.

As shown in FIG. 4, a stopper 31 is fastened and fixed to the outer surface of the movable frame 13 corresponding to the bracket 22 by the screw 23.
The tip of the stopper 31 has an inclined portion 31 inclined downward. Then, when the upper surface of the coin identification sensor 26 is inclined, the rotation of the sensor holder 24 is restricted by the outer surface of the sensor holder 24 abutting on the inclined portion 31a of the stopper 31.

Next, the operation of the coin separating apparatus 11 configured as described above will be described below. When separating the numbered ticket J and the coin K, the separation rollers 15, 18 approach each other, and the separation rollers 15, 18 rotate inward, respectively. Then, when a plurality of numbered tickets J and a plurality of coins K shown in FIG.
The numbered ticket J is wrapped around the separation rollers 15 and 18 and sent downward. On the other hand, the coin K is rotated or slipped downward along the passage A of the separation rollers 15 and 18 without being caught between the separation rollers 15 and 18, and the coin feed roller 2 is rotated.
0,21. And the coin K is a double feed roller 2
0 and 21, and is fed downward by the rotational force of both feed rollers 20 and 21. The dropped coin K passes through the detection passage 26a of the coin identification sensor 26 and the slit 24b of the sensor holder 24 and is stored in a collection case (not shown). When passing through the detection passage 26a of the coin identification sensor 26, the type of the coin K is identified.

When the numbered ticket J or the coin K is jammed between the separation rollers 15 and 18, when the movable frame 13 is moved to the right based on a signal from a jam detection sensor (not shown), The separation rollers 15, 18 are separated.
Then, the coin K or the numbered ticket J clogged between the separation rollers 15 and 18 falls downward and is removed.

At the same time, when the movable frame 13 moves rightward, the sensor holder 24 also moves rightward integrally with the movable frame 13. Due to this movement, the position of the arm 29b of the leaf spring 29 and the position of the engagement pin 28 in the sensor holder 24 are relatively shifted. Then, the arm 2 of the leaf spring 29
The sensor holder 24 rotates downward about the shaft 25 by its own weight in a state where 9b is in contact with the engagement pin 28. The outer surface of the sensor holder 24 is
The sensor holder 2 is brought into contact with the inclined portion 31a of the
4 is restricted.

Accordingly, the sensor holder 24 is rotated in conjunction with the separation operation of the separation rollers 15 and 18, and the upper surface of the coin identification sensor 26 is inclined downward with respect to the horizontal direction. or,
When the sensor holder 24 rotates, the sensor holder 24 is moved to the arm 2 of the leaf spring 29 with respect to the engagement pin 28.
9b, the impact force generated when the sensor holder 24 is inclined is reduced.

When a large number of coins K are rolling in the passage A when the separation rollers 15 and 18 are separated from each other, the coins K do not fall in the vertical direction. That is,
Since the coin K has momentum in the rolling direction, the coin K falls obliquely with respect to the vertical direction. However, since the upper surface of the coin identification sensor 26 is inclined with respect to the horizontal direction, the coin K is placed on the coin identification sensor 26. There is no.

After the jam of the numbered ticket J or the coin K sandwiched between the separation rollers 15 and 18 is eliminated, the movable frame 1
3 moves to the opposite side (left direction), the sensor holder 24
Also move to the left. At this time, the arm 29b of the leaf spring 29
Is pressed by the engagement pin 28, the sensor holder 24 rotates in the direction opposite to the above case. And
The sensor holder 24 has a leaf spring 29
Is elastically engaged by the arm portion 29b, the impact force generated when the sensor holder 24 returns to the original position is reduced.

This embodiment has the following effects (1) to (5). (1) The sensor holder 24 is rotated as the separation rollers 15 and 18 are separated from each other, and the upper surface of the coin identification sensor 26 is inclined downward with respect to the horizontal direction. for that reason,
When the separation rollers 15 and 18 are separated from each other, even if the coin K falls toward the coin identification sensor 26, it can be prevented from being put on the upper surface thereof. That is, when the separation rollers 15 and 18 return to the original positions, the detection passage 26a is not blocked by the coin K placed on the coin identification sensor 26. Therefore, the coin K can be reliably passed through the detection passage 26a of the coin identification sensor 26, and malfunction of the coin identification sensor 26 can be prevented.

(2) The coin discrimination sensor 26 is tilted in conjunction with the separating operation of the separation rollers 15, 18. Therefore, for example, as compared with the case where the coin discrimination sensor 26 is tilted after the separation operation of the separation rollers 15 and 18 is completed, a series of operation time from the separation of the separation rollers 15 and 18 to the approach of the coin again. Can be shortened. Therefore, after the rearranging ticket J or the coin K or the like is jammed in the separation rollers 15 and 18, it can be quickly performed until the separation roller J is restored.

(3) As means for inclining the coin discrimination sensor 26 in conjunction with the separating operation of the separation rollers 15, 18, the engagement pin 28 and the leaf spring are not controlled by a microcomputer using a motor or the like as a drive source. 29 and the like. Therefore, the failure location can be easily found by visual inspection, and maintenance can be easily performed.

(4) Since the coin identification sensor 26 is inclined by the weight of the sensor holder 24 and the coin identification sensor 26, no special mechanism or power source for inclining is required. Therefore, since the number of parts of the coin / coin separator 11 can be reduced, the structure can be prevented from becoming complicated, and the production cost can be reduced.

(5) The impact generated when the sensor holder 24 completes the rotation can be reduced by the elastic force of the arm 29b of the leaf spring 29. Therefore, the impact on the coin identification sensor 26 is reduced, and the coin identification sensor 26 can be protected from the impact, which contributes to prevention of failure.

The present invention may be configured as follows in addition to the above embodiment. (A) In the above-described embodiment, the ticket coin separating apparatus 11 for separating the numbered ticket J and the coin K of the bus is embodied. However, a ticket refers to a sheet having a qualification or the like displayed thereon. In addition to the ticket J, it can be embodied to separate the coin K from a bond, a securities, a meal ticket, a betting ticket, a postal ticket and the like.

(B) In the above embodiment, both separation rollers 1
Although the plurality of grooves 19 are formed on the outer peripheral surfaces of the grooves 5 and 18, the grooves 19 may be eliminated. When a separation roller having no groove 19 is used, the outer peripheral surfaces thereof are brought into contact when both separation rollers rotate.

(C) In the above embodiment, both separation rollers 1
Although the coin discrimination sensor 26 is tilted in conjunction with the separating operation of 5, 18, the tilting may not be separately performed in conjunction with the separating operation. Specifically, the coin identification sensor 26 may be tilted after the separation operation of the separation rollers 15 and 18 is completed, or the coin identification sensor 26 may be tilted before the separation operation is performed.

(D) In the above-described embodiment, the mechanism for inclining the coin discrimination sensor 26 has a mechanical structure including the engaging pin 28 and the leaf spring 29. Alternatively, for example, the coin identification sensor 26 may be tilted using a motor as a drive source under microcomputer control or the like.

(E) In the above-described embodiment, the sensor holder 24 is moved in the horizontal direction with respect to the engagement pin 28 in order to tilt the coin identification sensor 26. Or both may be moved in the horizontal direction.

(F) In the above-described embodiment, the coin identification sensor 26 is inclined so that the coin K is not placed on the upper surface of the coin identification sensor 26. Alternatively, for example, the coin identification sensor 26 may be moved upward so that the coin K is not placed on the upper surface thereof.

(G) Instead of interlocking with the separating operation of the separation rollers 15, 18, the coin K is placed on the upper surface of the coin discrimination sensor 26 using an elastic member such as a twist coil spring.
When the coin is placed, the coin identification sensor may be inclined by the weight.

Next, technical ideas other than the claims which can be grasped from the embodiment will be described together with their effects. (A) The coin separating apparatus according to claim 5, further comprising an elastic member (leaf spring 29) between the coin discriminating member and the engaging member. According to this configuration, it is possible to reduce an impact generated when the coin identification member is inclined.

[0037]

According to the first aspect of the present invention, since coins can be prevented from being placed on the coin identification member, malfunction due to the coin identification member can be prevented.

According to the invention described in claim 2, according to claim 1
In addition to the effects of the invention described in (1), coins can be reliably dropped from above the coin identification member. According to the third aspect of the invention, in addition to the effects of the first or second aspect, the coin discriminating member is inclined in conjunction with the separation operation of the separation roller. It is possible to shorten the time from when a ticket or a coin is jammed to when the jam is cleared.

According to the invention described in claim 4, according to claim 3,
In addition to the effects of the invention described in (1), since an extra mechanism is not required to incline the coin discriminating member, the number of parts is reduced accordingly. Therefore, it is possible to reduce the manufacturing cost of the entire coin / coin separator.
