DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin feeding device for feeding coins one by one using a rotating disk.

[0002]

2. Description of the Related Art A conventional coin feeding device is disclosed in, for example, Japanese Patent Application Laid-Open No. 7-296213, in which a coin on a rotating disk is rotated at a constant rotation speed of the rotating disk. Is moved along a peripheral wall provided around the rotating disk, passes one by one under a reverse rotation roller provided above the rotating disk, and is fed one by one to the outside of the rotating disk.

[0003] As described in Japanese Utility Model Publication No. 3-30932, coins on a rotating disk are rotated on a rotating disk at a constant rotation speed to a peripheral wall disposed around the rotating disk. The paper is moved one by one under the thickness regulating member disposed above the rotating disk, and is fed one by one to the outside of the rotating disk.

[0004]

However, in the conventional coin feeding device, coins continuously moving along the peripheral wall by the rotation of the rotating disk pass under the reverse rotation roller and the thickness regulating member. In this case, even if the coins fed outward from the rotating disk are fed continuously in a continuous state, or if the intervals of the fed coins are large, the intervals are not constant and vary. Coins that are fed from the coin feeding device perform processing such as identification and classification in the downstream area, but in the state where coins are continuously connected, defective identification or classification failure occurs. There is a problem in that it is necessary to provide an interval between coins fed from the coin feeding device in the middle of conveyance, and a configuration for that is required.

[0005] When a plurality of coins are jammed under the reverse rotation roller or the thickness regulating member and jammed, for example, the coin feeding operation is stopped, and the rotating disk is rotated in reverse to catch the coins. However, if a deformed coin or a large-diameter coin larger in diameter than the coin to be processed is mixed in coins to be fed from the coin feeding device, the rotating disk is reversed unless these coins are removed. Even if the coin feeding operation is resumed after the biting is temporarily eliminated, the coins are immediately bitten, so that the coin feeding operation is frequently stopped and the coin feeding processing efficiency is reduced.

Further, when the rotating disk has a small diameter or when the rotating speed of the rotating disk is low, the centrifugal force acting on the coin cannot be sufficiently obtained by the rotation of the rotating disk, so that the coin remains on the rotating disk. And there is a problem that the feeding efficiency is lowered.

[0007] The present invention has been made in view of such a point, and can stably pay out coins one by one at a fixed interval, and can rotate the rotating disk even if a coin is bitten. It is an object of the present invention to provide a coin dispensing device that can automatically cancel while continuing to operate.

The width of the transport surface 53 is formed to be wider than the diameter of the largest coin to be processed, and a reference wall 59 on one side continuous with the guide wall 55 contacts the peripheral edge of the coin C transported in the coin transport path 14.
However, a regulating wall 60 is formed on the other side.

A transport belt 61 for transporting the coin C toward the downstream side while moving the coin C toward the reference wall 59 is rotatably disposed above the transport surface 53. A plurality of pins 62 protrude from the transport belt 61 at equal intervals in opposition to the transport surface 53, and receive and transport coins C fed one by one from the gate portion 25 of the rotating disk 11 between adjacent pins 62. I do. The rotation of the conveyor belt 61 is configured to synchronize with the rotation of the rotating disk 11 so as to receive between the adjacent pins 62 coins C fed one by one from the gate portion 25 of the rotating disk 11.

A distribution roller 63 for distributing coins C between the coin transport path 14 and the rotating disk 11 is rotatably disposed at a starting end position facing the rotating disk 11 on the regulating wall 60 side of the transport surface 53.

At the entrance side of the transport surface 53, an exclusion port 64 is formed with reference to the reference wall 59.
A passage shifting lever 65 is pivotally supported on the swing shaft 66 as a fulcrum on the side 60 and is urged in a direction of entering the passage by a spring (not shown). The coin C to be processed conveyed in the coin conveyance path 14 is brought into contact with the passage approach lever 65 and brought into contact with the reference wall 59, and is pushed over the passage approach lever 65 to pass over the removal port 64. Foreign matter, coins smaller in diameter than the coin C to be processed, and the like are guided to the rejection port 64 by the passage approach lever 65 and dropped and eliminated.

In the downstream area of the coin transport path 14, for example, a coin identifying section for identifying a denomination and the like, a coin sorting section for classifying by denomination, and the like are provided.

As shown in FIG. 7, the rotating disk 11, the motor 23, the introduction plate 52 of the coin transport path 14, and the like are provided on an opening / closing support plate 68 which can be opened and closed about a support shaft 67 as a fulcrum. ing. The opening / closing support plate 68 is capable of swinging between a dispensing position at which coins C can be dispensed and an opening position which has been swung downward, and by swinging to the opening position, foreign matter remaining on the rotating disk 11 69 can be removed, coin jams can be cleared, and maintenance can be performed.

Next, the dimensional relationships of the coin feeding device will be described.

As shown in FIG. 4, a gap h1 between the rotating disk 11 and the regulating protrusion 45 of the fixed guide portion 43 is formed to have such a size that only one coin C to be processed can enter in the thickness direction. . For example, the maximum thickness coin of 500 yen is 1.8m
m, the minimum thickness coins of 1, 5, and 10 yen are 1.
In the case of 5 mm, the gap h1 is set to 2.2 mm which is larger than the thickness of the maximum thickness coin and smaller than the thickness of the minimum thickness coin.

As shown in FIG. 11B, the gap b between the rotating disk 11 and the concave portion 46 of the fixed guide portion 43 allows the passage of the coin C, which has risen by the dimension of the step 56 on the introduction surface 51. Acceptable dimensions, that is, the maximum thickness coin to be processed is
When the coin is raised on the step 51 by the dimension of the step 56, a gap is formed between the coin and the fixed guide portion 43 so that the coin does not come into contact with the coin. The width w between the inner peripheral side of the recess 46 and the inner peripheral side of the introduction surface 51 is such that the outer end side of the coin C is more than half loaded on the introduction surface 51 and the inner end side of the coin C is lifted upward from the rotating disk 11. In order to avoid contact with the fixed guide portion 43 at this time, the coin is formed to have a size of at least half the diameter of the largest coin to be processed.

The distance between the protruding portion 24 of the rotating disk 11 and the fixed guide portion 43 is such that the coin C cannot enter and the minimum thickness coin to be processed does not pass through and the eccentricity of the rotating disk 11 is taken into consideration. It is formed to the size of the interval. This interval is preferably as narrow as possible in order to leave small foreign substances mixed with coins C on the rotating disk 11 on the rotating disk 11 without feeding them out to the coin transport path 14. For example, the rotating disk When the vertical vibration due to the rotation of 11 is 0.5 mm, the size is obtained by adding a slight gap to the 0.5 mm.

The maximum width in the radial direction of the protrusion 24 and the fixed guide portion
43 is formed to have substantially the same width as the radial width. The maximum radial width of the protruding part 24 is
Since the diameter from the center of 11 to the protruding portion 24 is reduced, the centrifugal force acting on the coin C by the rotation of the rotating disk 11 is reduced, and the coin C may remain on the rotating disk 11.
Therefore, it is formed in a size up to about the diameter of the largest diameter coin to be processed. If the width of the rear end portion 27 of the protruding portion 24 is too small, the durability is likely to be reduced and the rear end portion 27 may be damaged.

The step 56 in the portion after the start end 51a of the introduction surface 51
Is a dimension capable of restricting the rising of the coin C from the portion after the starting end 51a, and is formed, for example, to about 1.5 mm, which is equivalent to the thickness of the minimum diameter coin to be processed.

Next, the coin feeding operation by the coin feeding device will be described.

First, the normal operation will be described.

A coin C is put into the guide body 12, and a rotating disk
Guided on 11.

The motor 23 is driven to rotate forward, and the rotating disk 11 is rotated in the feeding rotation direction F. By the rotation of the rotating disk 11,
While the coin C on the rotating disk 11 rotates with the rotating disk 11, the coin C is gradually moved to the peripheral portion of the rotating disk 11 by receiving centrifugal force. At this time, the friction member 38 in the central area of the upper surface of the rotating disk 11
Thus, the rotational force of the rotating disk 11 can be reliably transmitted to the coin C in contact with the friction member 38, and the coin C can be reliably moved to the periphery of the rotating disk 11. Further, in the central region of the rotating disk 11, the eccentric cap 35 rotates eccentrically and the stirring rod 36 having different projection lengths at both ends rotates eccentrically, so that the coin C inserted into the guide body 12 is broken and scattered around. Can be.

Among the coins C moved to the peripheral portion of the rotating disk 11, the coins which enter between the rotating disk 11 and the fixed guide portion 43 in a single layer state and abut on the guiding portion 33 of the projecting portion 24. C is guided to the rear end 27 side along the guiding portion 33, and the feeding rotation direction F
Is guided to the next gate section 25 following.

The coin C that has reached the next gate 25 following the payout rotation direction F through the guide portion 33 of the protrusion 24 is brought into contact with the protrusion 24 that has been guided until then and the next coin following the payout rotation direction F. It enters the gate portion 25 between the protrusions 24 and the next protrusion
24 and the gate portion 25 is
If the rotary position is opposed to 47, the rotary disk 11 orbits with the rotating disk 11 while sliding against the peripheral wall 47. At this time, the subsequent coin C guided along the guiding portion 33 of the protruding portion 24 in the feeding rotation direction F is the coin C that has entered the gate portion 25.
The coins C that have entered the gate portion 25 also act so as to be pushed outward.

The coin C which has entered the area of the gate section 25 without being guided by the guide section 33 of the projecting section 24 is pushed inside the sorting section 28 of the next projecting section 24 following the feeding rotation direction F. Abuts,
It is flipped in the inner diameter direction and returned to the center side of the rotating disk 11.

When the gate portion 25 reaches the rotation position facing the pay-out opening portion 48 of the peripheral wall 47, the coin C having entered the gate portion 25 is displaced by the centrifugal force caused by the rotation of the rotary disk 11. Through the coin transport path 14.

That is, as shown in FIG.
Reaches the rotation position facing the payout opening 48 of the peripheral wall 47, the outer end side of the coin C in the gate portion 25 enters the introduction surface 51 from the start end 51a of the introduction surface 51 through the payout opening 48. At the same time, the coin C comes into contact with the guide wall 55, and in this state, the coin C moves while being pushed by the outer pushing portion 31 of the projecting portion 24.

Subsequently, as shown in FIG. 10, when the coin C passes through the starting end 51a of the introduction surface 51 and reaches a position after the starting end 51a, the outer end of the coin C is higher than the rotating disk 11 by a step. The coin C is lifted on the introduction surface 51 having 56, and the coin C is obliquely straddling between the rotating disk 11 and the introduction surface 51. In this state, the coin C is pushed by the outer pushing portion 31 of the projecting portion 24. Move while being.

As shown in FIG. 11, when the coin C reaches the position below the roller 57, the coin C is held under the roller 57 and pressed against the introduction surface 51, and the inner end side of the coin C is turned on the rotating disk. The coin C rises from the top 11 and completely rises on the introduction surface 51, and in this state, the coin C moves while being pushed by the outer pushing portion 31 of the projecting portion 24.

As shown in FIG. 12, the coin C passing through the lower position of the roller 57 is rotated in synchronization with the rotating disk 11 while being pushed by the outer pushing portion 31 of the projecting portion 24. The transport belt 61 enters between the adjacent pins 62 of the transport belt 61 and is transported by the transport belt 61 to the downstream side of the coin transport path 14 in a holding state sandwiched between the pins 62.

As shown in FIG. 13, the coin C that has entered the gate portion 25 does not sufficiently move to the outer diameter side, and the outer end side of the coin C rises on the introduction surface 51, but the guide wall 55 When the player enters the lower position of the roller 57 without touching the coin C, the coin C
Of the coin C by the outer end side of the
Of the coin C is swung toward the outer diameter side with the portion where the coin C is held as a fulcrum, and is conveyed to the reference wall 59.

Further, as shown in FIG. 14, after the gate portion 25 has passed the starting end 51a of the introduction surface 51, the gate portion 25
Comes into contact with the step 56 and is circulated as it is without rising on the introduction surface 51.

The coin C following the coin C to be fed out
Has already entered the gate section 25,
Is disengaged from the feeding opening 48 and faces the peripheral wall 47, and the subsequent coin C is circulated with the rotating disk 11 without being fed.

The gate of such a rotating disk 11
The operation of dispensing the coin C from the coin 25 is sequentially performed at each of the gate portions 25 provided at three places of the rotating disc 11.
Each time one turns, three coins C are paid out. Therefore, even if coins C having different diameters are mixed, the coins can be fed out one by one at substantially constant intervals.

The rotating disk 11 during coin feeding is controlled by a control unit.
By the control by 39, as shown by a solid line in FIG. 8, a time zone of a constant rotation speed, a time zone of decreasing the rotation speed, and a time zone of increasing the rotation speed are controlled in series within one feeding period x. Thus, while the payout period x of the coin C is kept constant, the rotation speed V2 in the time zone where the rotation speed is the fastest is set.
However, as shown by the broken line in FIG. 8, a rotation speed higher than the average rotation speed V1 when the rotation speed is constant is obtained.

As described above, by changing the rotation speed of the rotating disk 11 and setting the time zone of the rotation speed V2 higher than the average rotation speed V1, the coins that stop on the rotating disk 11 and receive the static friction force C is easy to move, coin C
When the moves, it receives a kinetic friction force, and by changing from the static friction force to the kinetic friction force, the friction coefficient decreases. Therefore, the coin C can easily move in the outer diameter direction due to the centrifugal force, the coin C can be prevented from remaining on the rotating disk 11, and the coin C can be stably fed.

Next, the case where the coin C is bitten will be described.

As shown in FIGS. 15A and 15B, the outer end of one coin C enters between the rotating disk 11 and the fixed guide portion 43, and the lower side of the inner end of the coin C is inserted. , Another coin C enters,
When the coin C is caught in a wedge shape, the fixed guide portion 43 is fixed and does not rotate.
The coin C also stops moving in the feeding rotation direction F, and slips on the rotating disk 11.

As shown in FIG. 15C, the rotation of the rotary disk 11 causes the distribution portion of the next protrusion 24 following the rotation direction F to be fed out.
The inner pushing portion 32 of 28 collides with the biting coin C, the biting coin C is flipped in the inner diameter direction, and the biting is automatically canceled.

Even when only a part of the deformed coin enters between the rotating disk 11 and the fixed guide portion 43 and cannot enter completely, the inner pushing portion 32 of the distribution portion 28 of the projecting portion 24 is deformed. When the coin collides with the coin, the deformed coin is flipped in the inner diameter direction, and the rotating disk 11
Is returned to the central area. In addition, a large-diameter coin having a diameter larger than the coin to be processed cannot pass through the gate unit 25 and stops on the rotating disk 11. Also, coins that are thicker than the coin to be processed,
It cannot enter between the rotating disk 11 and the fixed guide portion 43, and stops at the central area of the rotating disk 11. Therefore, even if deformed coins, thick coins, large-diameter coins, and the like are mixed in the inserted coin C, these coins are not fed out, and these coins are placed on the rotating disk 11 without causing the coins to be clogged. Can be left.

As described above, the inner pushing portion 32 facing the inner diameter side of the gate portion 25 of the sorting portion 28 allows, for example, a coin C following the coin C entering the gate portion 25, a biting coin, and a deformed coin. A coin C that cannot enter the gate portion 25 can be pushed into the inner diameter direction and pushed out from the gate portion 25. Even when coins are clogged at the gate portion 25, the rotation of the rotating disk 11 can be prevented. It can be canceled automatically while continuing.

The normal biting can be automatically canceled while the rotation of the rotary disk 11 is continued. However, when the rotation of the rotary disk 11 is stopped due to the strong engagement of the coin C, the forward rotation of the motor 23 is stopped. Is stopped and switched to reverse rotation drive. At this time, the biting coin C is gradually pushed in the inner diameter direction of the rotating disk 11 by the guiding portion 33 of the projecting portion 24, and the biting is canceled. After the reverse drive of the motor 23 is continued for a predetermined time, the drive is returned to the forward drive and the coin feeding operation is continued.

As shown in FIG. 7, when the foreign matter 69 that cannot be fed out remains on the rotating disk 11, the opening / closing support plate 68 is swung to the lower open position,
The foreign matter 69 remaining on the rotating disk 11 can be removed. Since the introduction plate 52 is also opened by opening the opening and closing support plate 68, coin jamming on the introduction surface 51 can be eliminated.

Further, when a foreign object such as a clip or a washer is sent out to the coin transport path 14, the foreign object can be guided to the exclusion opening 64 by the passage pulling lever 65 and dropped and eliminated.

As described above, by the rotation of the rotating disk 11,
The coins C are inserted one by one in the thickness direction between the periphery of the upper surface of the rotating disk 11 and the fixed guide portion 43, and the rotating disk 11
The coins C enter one by one in the radial direction into the gate portion 25 provided at a position where the protruding portion 24 is not protruded in the peripheral portion of the upper surface of
While the gate portion 25 faces the peripheral wall 47, the passage of coins C from the gate portion 25 is restricted, and when the gate portion 25 faces the payout opening portion 48 provided in a part of the peripheral wall 47, Since the passage of the coins C from the gate portion 25 is allowed and the coins C are fed out one by one, the coins C can be fed out one by one at a fixed interval with the rotation of the rotating disk 11,
Coins C according to the rotation speed of the rotating disk 11 and the number of gates 25
Can be set arbitrarily.

Further, a distributing portion 28 is provided at an end of the protruding portion 24 facing the gate portion 25 in the feeding rotation direction F, and an outer pushing portion 31 of the distributing portion 28 facing the outer diameter side of the gate portion 25 is provided. , Gate part 25
The coin C that has entered into the gate portion 25 can be pushed out in the outer diameter direction and reliably fed out, and the coin C can be completely inserted into the gate portion 25 by the inner pushing portion 32 facing the inner diameter side of the gate portion 25 of the sorting portion 28. A force that abuts against the coin C and tries to push it back in the inner diameter direction can be given, and even when the coin C is bitten between the rotating disk 11 and the fixed guide portion 43, the rotation of the rotating disk 11 is continued. The bite can be automatically eliminated as it is.

Also, the starting end 51 of the introduction surface 51 of the coin transport path 14
The height of a is such that the coin C can be received from the gate portion 25 of the rotating disk 11 onto the introduction surface 51, and the starting end side of the introduction surface 51
The height after 51a extends from the gate 25 of the rotating disk 11 to the introduction surface 51.
Since the height has the step 56 that regulates the acceptance of the coin C upward, the coin C is received on the introduction surface 51 only at the start end 51a of the introduction surface 51, and the coin C enters from the middle of the introduction surface 51. Coin C between the rotating disk 11 and the coin transport path 14
Of the coin C can be prevented, and the coin C can be reliably fed.

Further, the coin C entering the gate 25 is regulated to one sheet in the thickness direction by the regulating protrusion 45 provided on the inner peripheral side of the stationary guide 43 facing the rotating disk 11, and then the fixed guide 43 is fixed. The coin C placed on the introduction surface 51 can be allowed to pass through the recessed portion 46 provided on the outer peripheral side facing the rotating disk 11 of 43.

Further, since the width of the recess 46 in the radial direction is formed to be at least half the diameter of the largest coin to be processed, the coin C whose half or more of the diameter has entered the introduction surface 51 is placed on the introduction surface 51. Tolerable to go up.

Further, above the introduction surface 51 of the coin transport path 14,
By the roller 47 arranged rotatably in the direction of the coin transport path,
The coin C remaining on the rotating disk 11 that is not sufficiently placed on the introduction surface 51 is gripped, and the coin C can be guided to be placed on the introduction surface 51 with the gripped portion as a fulcrum.
The coin C can be prevented from being caught between the coin and the coin transport path 14, and the coin C can be reliably fed out. When the roller 57 is driven to rotate, the action of guiding the coin C to be placed on the introduction surface 51 as in the case where the roller C is rotatable is not obtained, and the coin C is moved between the projecting portion 24 and the distribution roller 63. Clogging is likely to occur and clogging is likely to occur.

Further, in order to change the rotation speed of the rotating disk 11 in each paying cycle while keeping the payout cycle of the coin C by the rotation of the rotating disk 11 constant, for example,
The coin C can be fed out by centrifugal force by changing the relationship between the rotating disk 11 and the coin C from static friction to kinetic friction, even if the diameter of the rotating disk 11 is small or the rotating speed of the rotating disk 11 is low and sufficient centrifugal force cannot be obtained. Coin C on the rotating disk 11
Can be prevented, and the coin C can be stably fed out.

Note that the payout interval of the coins C from the coin feeding device can be set according to the rotation speed of the rotating disk 11 and the number of gates 25. For example, as shown in FIG. 16, by providing two projections 24 and two gates 25 each,
It can be set so that two coins C are sequentially fed out one by one at a constant interval by one rotation of the rotating disk 11. When the diameter of the rotating disk 11 is large, the protrusion 24 and the gate 25
May be provided three or more.

When the diameter of the rotating disk 11 is small,
With the coin C hitting the tip 26 of the projection 24, the rotating disk 11
Although the coin C may remain at that position despite the rotation, the friction member 38 is not provided near the tip end portion 26 of the protrusion 24. In such a case, instead of disposing the annular friction member 38 on the upper surface of the rotating disk 11, a belt-shaped friction member is
This can be dealt with by arranging radially except for the vicinity of 26.

The distribution part 28 of the protruding part 24 may be triangular or semicircular, and the guiding part 33 may be linear.
In each case, the same operation and effect can be obtained.

Although the gate 25 is composed of the rotating disk 11 and the fixed guide portion 42 of the guide body 12, the rotating disk 11 itself may be provided with a gate through which coins C can pass one by one. In this case, the same operation and effect can be obtained.

Further, when the transport belt 61 having the pins 62 is used as the transport belt 61 for transporting the coins C in the coin transport path 14, the transport of the coins C can be ensured. When a round belt without the pins 62 is used, it is not necessary to synchronize the round belt with the rotating disk 11, and the configuration can be simplified.
