Reciprocate.

[0006] In the front half of the upper slider 116, a round hole 120 for dropping coins downward is formed corresponding to each of the holding cylinders 102. In the round hole 120, each change slider 118 slides from behind. It comes to face freely. A round hole 1 is provided at the front end of the upper slider 116.
Corresponding to 20, there is provided a slide projection 121 for pulling out coins one by one from each holding cylinder 102. The movement of the slider body 114 is performed by moving the coin into the slit 1 of the holding cylinder 102.
The moving stroke is to pull out about 2/3 from 07, and the coin is dropped from the round hole 120 by pulling out the coin from the holding cylinder 102 by 2/3. In this case, when the change slider 118 is not restricted by the stopper pin of the selection device, the upper and lower sliders 116,
117, the coin is dropped from the round hole 120. When the coin is restricted by the stopper pin, the coin is left unmoved and acts to close the round hole 120 so that the coin is prevented from dropping. Has become.

On the other hand, the wiper 115 has a base end engaged with a long groove 122 formed in the lower cover 106 and an intermediate portion rotatably supported by a pin 123 projecting from a lower surface of the lower slider 117. In conjunction with the reciprocating movement of the slider body 114, the slider body is irregularly rotated on the lower cover 106 between a position facing the front-rear direction and a position facing the left-right direction.
That is, in this conventional example, coins of four holding cylinders 102 out of the five holding cylinders 102 are replaced with slider body 114.
And the remaining coins in the rightmost storage cylinder 102 are dropped on the lower cover 106 and then paid out by the rotation of the wiper 115.

The lower cover 106 is provided with the four holding cylinders 10.
A payout slot 124 into which the second coin is directly dropped,
And a receiving portion 125 into which coins of the storage cylinder 102 at the right end are dropped. A guide wall 126 is formed on the receiving portion 125 along a rotation locus of the wiper 115.

Next, the operation of dispensing change will be briefly described with reference to FIGS. To explain an example of paying out coins in the rightmost holding cylinder 102 shown in the drawing by a change command, first, the motor 110 of the driving device 104 starts rotating, and among the stopper pins of the selection device, the leftmost holding cylinder Other stopper pins protrude except for the stopper pin corresponding to. As the rotation of the motor 110 proceeds, the top 113 makes the slider body 114 move backward from the steady state, and the wiper 115 is turned to the horizontal position via the slider body 114. With the forward movement of the slider body 114, the slide protrusion 121 of the slider body 114 catches the lowermost coin, and the holding cylinder 102
It operates so that it may be pulled backward from the slit 107 of FIG.
At this time, due to the action of the stopper pin of the selection device, only the change slider 118 corresponding to the rightmost holding cylinder 102 moves together with the upper and lower sliders 116 and 117, and the other change sliders 118 partially move with the bottom plate of the holding cylinder 102. Left behind in the same state. Therefore, the rightmost holding cylinder 10
Only two coins are dropped into the receiving portion 125 of the lower cover 106 from the opening 109 of the bottom base 103 (FIG. 1).
1).

When the rotation of the motor 110 further advances, the slider body 114 shifts from the forward movement to the backward movement by the action of the top 113, and once the holding cylinder 102 other than the rightmost holding cylinder 102 is pulled out of the slit 107 to the middle. Return the coins to their original positions. At the same time, the coins dropped from the storage cylinder 102 at the right end are dropped into the payout opening 124 by the rotation of the wiper 115 so as to be flipped (the state of FIG. 12).

[0011]

In such a conventional coin processing apparatus, a cam mechanism for reciprocating the slider 105 includes a rotating cam projection 121 and a one-character cam groove 1.
In the reciprocating operation of the slider 105, the transition from the forward movement to the backward movement is continuously performed, and the reciprocating rotation of the wiper 115 is also continuously changed from the forward movement to the backward movement. It is done on a regular basis. Therefore, when trying to increase the coin payout speed, the round hole 12
The coin dropped from zero bounces on the receiving portion 125 of the lower cover 106, and the wiper 115 moves forward before the bound cannot be accommodated, and the wiper 115 passes under the coin. is there. In such a state, coin dispensing mistakes occur, the device is damaged, coins are jammed, and the like, and in practice, a certain limit is imposed on the coin dispensing speed.

The present invention has been made in view of the above problems, and has as its object to provide a coin payout apparatus which can pay out coins reliably even when the payout speed is increased.

[0013]

In order to achieve the above object, the present invention provides a holding cylinder for holding coins in a stacked state, a coin receiving tray for receiving coins dropped from the holding cylinder, and an extension of the coin receiving tray. A payout port provided at the set end, a wiper member slidably facing the surface of the coin receiver, and configured to be reciprocally rotatable between a return position and a payout position, and a reciprocating motion for operating the wiper member. Means and the forward movement of the wiper member,
Dropping means for dropping the coins in the holding cylinder into the coin receiving tray, the reciprocating means for moving the wiper member to the payout position, then returning to the return position, and the wiper member In the coin dispensing device in which the upper coin is kicked into the payout slot, the wiper member engages with the reciprocating means between the turning base and the kicking end, and at the dispensing position, the turning base has A braking member that is loosely engaged with the coin tray and that brakes the movement of the kick end of the wiper member when the wiper member transitions from forward movement to backward movement is provided on the surface of the coin tray. It is characterized by the following.

In this case, the braking member is an elastic body slightly projecting from the surface of the coin receiver, and it is preferable that at least a part of the elastic body is disposed facing the falling area of the coin.

[0015]

When the wiper member is reciprocated to the payout position (forward rotation) by the reciprocating means, the coins in the holding cylinder are dropped onto the coin receiving tray by the dropping means, and subsequently, the return position. Is moved back (return), the wiper member kicks the coin on the coin receiving plate into the payout slot. in this case,
The wiper member is engaged with the reciprocating means between the pivot base and the kick-in end, and in the payout position, is loosely engaged with the coin tray at the pivot base, and is also provided on the surface of the coin tray. When the wiper member transitions from the forward movement to the reverse movement, the braking member that brakes the movement of the kick end of the wiper member is provided when the wiper member transitions from the forward movement to the backward movement. The kicking end of the wiper member is braked, and the recoil thereof causes the pivot base, which is located on the opposite side of the reciprocating means, to move slightly by the amount loosely engaged with the coin receiving tray. Then, the kicking operation (movement) of the wiper member is instantaneously stopped. Thereby, even if the speed of the reciprocating rotation of the wiper member is increased, it is possible to sufficiently secure the time for the bouncing of the coin dropped on the coin receiving tray to settle.

Further, in this case, the braking member is an elastic body slightly projecting from the surface of the coin receiving table, and at least a part of the elastic body is disposed so as to face the coin falling area. The kicking end of the member is braked when riding on the elastic body, and the elastic body buffers the coin from falling. Therefore, the kick-in timing of the wiper member can be slightly delayed, and the bouncing of coins can be suppressed as much as possible.

A slit (opening) 22 for pulling down from b is formed. The bottom plate portion 22a of the slit 22 is formed in an arc shape corresponding to the outer peripheral edge of the coin to be stored, and when the coins in the storage cylinders 7a and 7b are pulled out rearward by about 2/3, they fall downward. It has become. A cutout opening 23 is formed in the bottom plate 21 of the holding cylinders 7a and 7b so as to extend across the bottom plate 21 in the front-rear direction to the slit 22. A slide protrusion 68 of the slider 12 described later is formed in the cutout opening 23. It is slidable.

The bottom base 9 is made of resin or the like.
Receiving part 3 for holding cylinders 7a, 7b in the first half with partition 31
2, an attachment portion 33 for the drive device 10 and the selection device 11 is formed in the rear half, and an opening 34 for dropping coins is formed below the partition 31. Opening 34
Extends below the slits 22 of the holding cylinders 7a and 7b, and the coins dropped from the slits 22 pass directly through the openings 34 and are dropped further downward. A slide rail 35 is formed in the receiving portion 32 so as to match with the notch opening 23 of the holding cylinders 7a and 7b, and the slider 12 facing the notch opening 23 is formed.
The slide projection 68 is guided by the slide rail 35 and is slid in the front-rear direction.
The upper surface of the receiving portion 32 and the lower surface of the mounting portion 33 have a step in which the slider 12 is sandwiched. Etc. are formed.

On the other hand, the mounting portion 33 of the bottom base 9 has
Screw holes for mounting the drive device 10 and fitting grooves for mounting the selection device 11 (both not shown)
Are formed, and a pair of rectangular openings 36, 36 into which respective frames 43 of the driving device 10 described later are inserted, and five small holes 37, 37, into which respective stopper pins 52 of the selecting device 11 described later are inserted. 37, 37, 37 are formed.

The drive unit 10 includes a motor 41 as a drive source of the slider 12, a reduction gear train 42 for reducing the rotation of the motor 41 and dividing the rotational power into two, and a reduction gear train 4
It is composed of a pair of frames 43, 43 for converting two rotations into reciprocating motion. The reduction gear train 42 includes a driving gear 44 of the motor 41 and a first intermediate gear 45 meshing with the driving gear 44.
And a pair of second intermediate gears 46, 46 meshing with the first intermediate gear 45, respectively, and a pair of output gears 47, 47 meshing with the second intermediate gears 46, and are accommodated in a gear box (not shown). . Shaft 47a of each output gear 47
Is fixed to a frame 43 inserted from below.
A cam projection 43a is formed on the periphery of the lower surface of the top 43, and this cam projection 43a is adapted to engage with a cam groove 66 of the slider 12 described later. That is, when the motor 41 is driven, both the frames 43, 43 rotate simultaneously, and the slider 12 reciprocates once for each rotation of the both frames 43, 43.

The selection device 11 includes five solenoids 51, 51, 51, 51, 51 corresponding to the respective holding cylinders 7a, 7b.
And five stopper pins 52, 52, 52, 52, 52 that move up and down by each solenoid 51. The tip of each stopper pin 52 penetrates each small hole 37 of the bottom base 9, and projects downward from the lower surface of the bottom base 9 by excitation and demagnetization of the solenoid 51. When the stopper pin 52 projects,
It engages with the rear end of the change slider 65 of the slider 12, which will be described later, to restrict the movement of the change slider 65. When the slider 12 is immersed, it acts to release this restriction. That is, based on the change command, the solenoid 51 is selectively energized, and the specific change slider 65 is immobilized against the movement of the slider 12 so that change other than the desired denomination can be prevented from falling. It has become.

The slider 12 comprises a slider body 61 and a wiper (wiper member) 62 which rotates in conjunction with the slider body 61. The slider body 61
The wiper 62 is provided so as to be inserted between the upper surface of the receiving portion 32 of the bottom base 9 having a step and the lower surface of the mounting portion 33. It is provided in a gap constituted by the upper surface. In this embodiment, the coins in each of the holding cylinders 7a and 7b are paid out through the payout port 14 of the lower cover 13 by the reciprocating movement of the slider body 61, but only the coins in the spare holding cylinder 7b are dispensed. Once the lower cover 1
3, and then the payout port 1 is
It drops to 4.

The slider main body 61 is configured so that a change slider 65 is sandwiched between an upper slider 63 and a lower slider 64, and the bottom base 9 is formed as a whole.
The change slider 65 is slidable with respect to the upper slider 63 and the lower slider 64.

A cam groove 66 is formed on the rear upper surface of the upper slider 63 to engage with the cam projection 43a of the top 43. The slider 43 is reciprocated by the top 43 (cam projection 43a) and the cam groove 66. A cam mechanism is provided. The cam groove 66 has a flat chevron-shaped contour curve, and the cam mechanism is configured so that a top portion forms a flat displacement curve. That is, when the cam projection 43a makes one reciprocation in the cam groove 66 by one rotation of the top 43, the slider 12 makes one reciprocation between the steady position and the dispensing position. At this time, the slider 12 moves back from the forward movement. The slider 12 is temporarily stopped when shifting to the backward movement and when shifting from the backward movement to the forward movement.

In the first half of the upper slider 63, each holding cylinder 7
Corresponding to a and 7b, a round hole 67 for dropping coins downward is formed, and a slide projection 68 for drawing coins from each of the storage cylinders 7a and 7b is provided at the front side of the round hole 67. The slide projection 68 faces the inside of the holding cylinders 7a, 7b from the cutout openings 23 of the holding cylinders 7a, 7b, and projects into the holding cylinders 7a, 7b slightly smaller than the thickness of the coin. Thereby, the coins in the holding cylinders 7a and 7b are pulled out one by one. An elongated hole 69 is formed at the rear portion of the upper slider 63 in an axial line of each slide projection 68.
The stopper pin 52 of the selection device 11 faces 9. Thus, even if the stopper pin 52 projects, interference between the stopper pin 52 and the upper slider 63 is prevented.

On the other hand, the reciprocating movement of the slider body 61 is such that the moving stroke of pulling out coins from the slits 22 of the holding cylinders 7a and 7b by about 2/3, that is, the holding cylinders 7a and 7b and the round holes 67 of the upper slider 63 match. From the position at which the bottom plate portion 22a of the slit 22 of the holding cylinders 7a and 7b and the front end of the round hole 67 of the upper slider 63 match, and coins are pulled out of the holding cylinders 7a and 7b by 2/3. Thus, the coin is dropped downward from the round hole 67.

Each change slider 65 includes an upper slider 6
3 is guided by the lower surface of the lower slider 64 and the upper surface of the lower slider 64, and slidably faces the round hole 67 of the upper slider 63 from behind. The change slider 65 is disposed such that the upper surface thereof is flush with the upper surface of the bottom plate 21 of the holding cylinders 7a and 7b, and faces the round hole 67 of the upper slider 63.
The coin is prevented from falling from the round hole 67. On the other hand, a hook portion 70 is formed at a central front portion of the change slider 65 by making a cut in a “U” shape. Engages in a click. That is, the change slider 65
In a state where the stopper pin 52 of the selection device 11 is not engaged (submerged state), the lower slider 64 restricts
While retracted from the round hole 67 of the upper slider 63, it reciprocates with the upper and lower sliders 63, 64. On the other hand, in the state where the stopper pin 52 is engaged (projected state), the change slider 65 is restricted by the stopper pin 52 and stops even when the upper and lower sliders 63 and 64 reciprocate. It relatively faces the round hole 67.

As described above, when the change slider 65 reciprocates together with the upper and lower sliders 63 and 64, the round hole 67 is not closed, and the slits 22 of the holding cylinders 7a and 7b are not closed.
The coin pulled out of the coin is dropped downward through the round hole 67. Conversely, when the change slider 65 is stationary, the change slider 65 is moved by the bottom plate 2 of the holding cylinders 7a, 7b when the upper and lower sliders 63, 64 move forward.
1 and supports the coin drawn out of the slits 22 of the holding cylinders 7a and 7b to prevent the coin from falling from the round hole 67. It should be noted that the change slider 65 does not depend on the stopper pin 52 but the engagement groove 7 of the lower slider 64.
Although not shown, a regulating pin facing the elongated hole 69 of the upper slider 63 is provided on the lower surface of the bottom base 9 so as to be able to return to the original position when it deviates from 1. I have.

On the lower surface of the lower slider 64, an interlocking pin 72 for interlocking the wiper 62 with the slider body 61 is provided. The interlocking pin 72 is rotatably engaged with the wiper 62.

As shown in FIGS. 3 and 4, the wiper 62 is formed in a flat bar shape, and a downwardly projecting portion (rotating base) 73 is provided at a base thereof at an intermediate portion between the projecting portion 73 and the kick-in end 74. A pin receiving portion 75 is formed. The protrusion 73 is engaged with a regulating groove 81 formed in the lower cover 13, and the pin receiving portion 75 is engaged with an interlocking pin 72 of the lower slider 64. When the slider body 61 reciprocates, the wiper 6
2 is reciprocally rotated on the lower cover 13 between a horizontal position facing the left-right direction and a vertical position facing the front-rear direction. That is, when the slider main body 61 is at the steady position, the protrusion 73 is regulated by the regulation groove 81 and is shifted toward the right end, and the wiper 62 is in the vertical position (return position) (the state of FIG. 3). When the slider body 61 moves forward to the dispensing position from this state, the protrusion 73 escapes to the left end side of the regulating groove 81, and the wiper 62 rotates to the horizontal position (dispensing position) (state in FIG. 4). Subsequently, when the slider body 61 returns to the normal position, the protrusion 73 is moved to the right end side of the regulating groove 81 so as to be pulled, and the wiper 62 returns to the vertical position (the state of FIG. 3).

In this case, the left end of the regulating groove 81 slightly projects forward, and the wiper 6 in the lateral position
In this lateral position, the second protrusion 73 is in a loosely engaged state in which it can move slightly forward.

The lower cover 13 is formed in a rectangular shape in conformity with the bottom base 9, and has a horizontally elongated outlet 14 on the left side and an inclined portion 82 inclined toward the outlet 14 on the right side of the outlet 14. A flat receiving portion 83 is formed on the right side of the portion 82, and a guide wall 84 is formed at a front portion of the receiving portion 83 so as to extend to the inclined portion 82 along the rotation locus of the wiper 62. The payout opening 14 is arranged corresponding to the three holding cylinders 7a from the left of the four holding cylinders 7a, and the inclined portion 82 is arranged corresponding to the remaining one holding cylinder 7a.
Further, the cradle part 83 is provided corresponding to the spare holding cylinder 7b. That is, the coins in the three holding cylinders 7a are directly dropped into the payout port 14 by the forward movement of the slider body 61, and the coins in the remaining one holding cylinder 7a are
It is dropped into the payout port 14 through the inclined portion 82. On the other hand, the coins in the spare holding cylinder 7b are once dropped on the cradle portion 83 of the lower cover 13 by the forward movement of the slider body 61, and subsequently the kick of the wiper 62 which rotates by the backward movement of the slider body 61. The guide end 84 guides the guide wall 84 so as to be repelled, and is dropped from the inclined portion 82 into the payout opening 14.

On the other hand, as shown in FIGS. 4 and 5, a spring portion 85 is formed in the receiving portion 83 from the kick-in end 74 of the wiper 62 located at the lateral position to the coin falling area. The spring portion 85 is configured such that a “U” -shaped groove is formed in the cradle portion 83 and a half portion is formed to be thin, so that a spring force can be exerted in the vertical direction. The upper surface of the spring portion 85 slightly protrudes from the upper surface of the cradle portion 83,
It is formed in a gentle mountain shape in the longitudinal direction. When the wiper 62 in the horizontal position starts to rotate to the vertical position, the push-in end 74 of the wiper 62 causes the spring portion 8 to move.
Climb up the slope of No. 5 and receive braking force here. on the other hand,
When the coin falls on this portion, the coin hits the spring portion 85, and its falling force is buffered, and the bouncing is suppressed.

Next, the operation of dispensing change will be described step by step with reference to FIGS. When the coin dispensing device 5 is in a steady state, the slider main body 61 is at a steady position where it is moving forward, and the wiper 62 is at a vertical position (return position). From this state, an example will be described in which a 10-yen coin is paid out from the spare holding cylinder 7b at the left end in the drawing according to a change command.

First, the change command causes the motor 41 of the drive device 10 to start rotating, and the other stopper pins 52 of the selection device 11 except for the stopper pin 52 corresponding to the spare holding cylinder 7b. 52 protrudes. When the rotation of the motor 41 advances, the two pieces 43, 43 move the slider body 61 backward through the reduction gear train 42, and the wiper 62 rotates to the horizontal position (payout position) via the slider body 61. Is done. Along with the forward movement of the slider body 61, the slide projection 68 of the slider body 61 operates so as to catch the coin at the lowermost position and pulls the coin backward from the slit 22 of each of the storage cylinders 7a and 7b. At this time, the stopper pin 5 of the selection device 11
By the action of 2, only the change slider 65 corresponding to the spare holding cylinder 7b moves rearward together with the upper and lower sliders 63, 64, and the other change sliders 65 are left stationary. As a result, only the coins in the spare storage cylinder 7b are dropped onto the receiving portion 83 of the lower cover 13 from the opening 34 of the bottom base 9 (see FIGS. 7 and 9).

Further, when the rotation of the motor 41 advances, the slider body 61 and the wiper 62
After stopping once, it moves from forward movement to return movement. When the slider main body 61 moves back, coins that have been pulled out halfway (about 2/3 of the diameter of the coin) from the slit 22 in the holding cylinders 7a other than the spare holding cylinder 7b are supported by the change slider 65 and then returned. To the position. That is,
The coin is once moved backward by the slider body 61, but is returned to the original position without being dropped. On the other hand, the coin dropped from the spare holding cylinder 7b is
The slider body 61 is guided by the guide wall 84 by the rotation (reverse movement) of the wiper 62 in accordance with the return movement, and is dropped into the payout opening 14 as if being flipped (FIGS. 6 and 8).
reference).

In this case, when the wiper 62 starts to rotate, the kick-in end 74 of the wiper 62 receives a braking force from the slope of the spring portion 85, and the projection 73 of the wiper 62 is caused to react with the braking force by the reaction groove 81. And moves slightly forward and hits the front wall of the restriction groove 81. Here, since the forward movement of the projection 73 is regulated by the regulation groove 81, the kick-in end 74 moves over the spring portion 85 against the braking force of the spring portion 85 and rotates. Go. That is, the coin is kicked out.

As described above, when the wiper 62 linked to the slider body 61 is shifted from the forward movement to the backward movement by the cam mechanism, the wiper 62 is temporarily stopped, and the wiper 62 itself is also moved backward by the spring portion 85. Is stopped instantaneously, so that a sufficient time can be secured for the coin to fall into the cradle portion 83 and stop. In addition, since the coin is restrained from bouncing by the spring portion 85, the coin can be stopped on the cradle portion 83 in a short time. Therefore, even if the payout speed is increased, the coins can be paid out reliably.

Further, since the solenoids 51 are provided corresponding to the respective change sliders 65, the responsiveness is improved, and a complicated power transmission between the solenoids 51 and the change sliders 65 is required. There is no need to provide a mechanism, and a simple structure with less failure can be provided.

In this embodiment, the payout device for coins has been described. However, it is needless to say that the present invention can be applied to a payout device for coins used in game machines and the like, in addition to currency exchange machines. Further, as a braking means, a leaf spring, a sponge,
Rubber or the like may be embedded in the coin receiver and used.

[0044]

As described above, according to the coin dispensing apparatus of the present invention, the wiper member is momentarily stopped by the braking means when shifting from the forward movement to the backward movement. It is possible to secure a sufficient time for the coin dropped in the coin to settle on the coin receiving tray, and to pay out the coin reliably. Therefore, there is an effect that the payout speed of coins can be increased and the coin payout time can be shortened accordingly.
