DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a predetermined processing such as counting or packaging coins, and more particularly to a coin processing machine having a rotating disk for separating and feeding out inserted coins one by one. .

[0002]

2. Description of the Related Art In a coin processing machine having a rotating disk which separates and feeds out inserted coins one by one by rotating, most of the jams generated when coins are fed by the rotating disk are mostly removed from the rotating disk. This is a coin jam that occurs in the vicinity of a coin outlet for paying out coins. When such a coin jam occurs, the rotation of the rotating disk is restricted or overloaded, and a state in which coins are not fed occurs. . As a countermeasure against the occurrence of such a jam, a coin detecting means for detecting a flow of coins fed from a rotating disk is provided, as in a coin processing machine disclosed in Japanese Patent Application Laid-Open No. 57-153395. When the coin detecting means does not detect a coin for a predetermined time at the time of feeding, the driving of the rotating disk in the direction of feeding coins is stopped, and then, the coin is rotated in a direction opposite to the direction of feeding coins. There are things that eliminate jams in coins. However, in this case, even if the jam can be actually eliminated, the rotating disk continues to be driven from the occurrence of the jam until the coin detecting means stops detecting the feeding of the coin for a predetermined time. There is a problem that a large load is applied to a mechanism related to driving of the rotating disk or a place where a jam occurs, and damage or the like is likely to occur. As a solution to such a jam of coins, as disclosed in Japanese Utility Model Laid-Open No. 49-120295, a rotating disc and a motor serving as a drive source for rotating the rotating disc are connected to each other as in a coin sorting and counting apparatus disclosed in Japanese Utility Model Laid-Open No. 49-120295. Between the main spindle
By providing a clutch that causes a slip on the drive of the motor when the rotation of the rotating disk is overloaded due to jammed coins, it is possible to prevent damage to each mechanism when a jam occurs. Therefore, by applying such a clutch to the coin processing machine described above, it is also possible to prevent damage and the like.

[0003]

However, in the case of the above construction, the clutch slips even when the rotating disk is rotated in the reverse direction, even if the jam is eliminated by rotating the rotating disk in the reverse direction. Therefore, the problem that the rotating disk cannot be rotated in the reverse direction and the jam cannot be eliminated was expected. Therefore, it is an object of the present invention to prevent overloading of each mechanism related to payout when a jam of a coin occurs and to prevent the damage, and then to eliminate the jam by reverse rotation of the rotating disk. It is to provide a coin processing machine that can do it.

[0004]

According to a first aspect of the present invention, there is provided a coin processing machine in which coins are inserted and the inserted coins are separated one by one by rotating forward. Rotating disc and motor rotation
And a drive unit for forward and reverse rotation of the rotary disk with a force, the driving unit, the possible drive torque transmission during forward rotation to the rotating disk of the rotary disk is capable of transmitting to the rotating disk at the time of reverse rotation coin processor odor ing is smaller than the torque
The driving unit generates a slip when a predetermined driving torque smaller than a driving torque that can be transmitted to the rotating disk is generated between the rotating disk and the rotating disk during normal rotation of the rotating disk by the motor. And transmission preventing means for preventing further driving torque from being transmitted to the rotating disk, the transmission preventing means being configured to reversely rotate the rotating disk by the motor.
During rotation, the rotational force from the motor is
Transmission to the rotating disk, and winding around the pulley
The contact area of the driven belt is increased,
When the rotating disk rotates forward, the one-way clutch
The rotation from the motor without transmitting the torque from the belt
By transmitting the rolling force to the rotating disk with a single belt,
And the contact area of the belt wound around the pulley
It is characterized by being made smaller . This allows
Since the driving torque that the driving unit can transmit to the rotating disk during the normal rotation of the rotating disk is small, a large driving torque is not transmitted to each mechanism related to the feeding when a coin jam occurs. On the other hand, since the driving torque that can be transmitted to the rotating disk by the drive unit when the rotating disk is rotated in the reverse direction is large, the rotating disk can be rotated in the reverse direction even when a jam occurs. When a predetermined driving torque is generated between the rotating disk and the rotating disk during the forward rotation of the rotating disk, the transmission preventing means of the driving unit generates a slip, thereby reducing the driving torque to the rotating disk. Further, at the time of the reverse rotation of the rotating disk, it is possible to transmit a driving torque exceeding the predetermined driving torque, so that the driving torque to the rotating disk can be increased.

[0005] A coin processor according to a second aspect of the present invention relates to the coin processor according to the first aspect, wherein the coin is processed when the rotating disk is rotated forward.
The belt that transmits dynamic torque to the rotating disk is a round belt
The drive torque is applied to the rotating disk during the reverse rotation of the rotating disk.
The belt to be transmitted to the disk is the round belt and the V belt.
It is characterized by that.

FIG. 1 shows a first embodiment of the present invention.
This will be described below with reference to FIGS. The coin processing machine according to the first embodiment, for example, accumulates a predetermined number of coins of a specified single denomination, and performs a packaging process for packaging the accumulated coins and a denomination specified without performing the packaging process. 1 and FIG. 2 below the hopper (not shown) into which coins are inserted from the outside. The coin supply device 11 shown is provided.

The coin supply device 11 performs a feeding process in which a large amount of coins are inserted, and the inserted coins are separated one by one and fed out. A support member 12 is provided on an unillustrated body side of the coin processing machine.
The support member 12 supports a rotary shaft 15 rotatably about a vertical axis via an upper large-diameter bearing 13 and a lower small-diameter bearing 14. The rotating disk 16 fixes the center position of the rotating disk 15 to the rotating shaft 15 in a state where the rotating disk 16 is horizontally arranged above the supporting member 12.

A mounting member 18 is fixed to the lower side of the support member 12, and a motor 19 is mounted on the mounting member 18 so that a drive shaft 20 can rotate about a vertical axis. A drive shaft 20 of the motor 19 has a gear 21
The gear 21 is engaged with a gear 22 fixed to a portion of the rotating shaft 15 below the rotating disk 16.

An annular guide 24 having an arc shape in a plan view is fixed to the support member 12 so as to be coaxial with the rotating disk 16 on the outer periphery of the rotating disk 16. Around the rotating disk 16 except for the annular guide 24, a thickness regulating plate 25 having an arc shape in a plan view is fixed to the support member 12 so as to be coaxial with the rotating disk 16. The thickness regulating plate 25 has a feeding outlet 26 having a height corresponding to the thickness of one coin in a predetermined range in a state where the position of the upper surface 16a of the rotating disk 16 and the lower edge thereof are aligned. It is formed through. Here, the annular guide 24 and the thickness regulating plate 25 have the same height position at the upper end, and these two are cylindrical.

On the side opposite to the rotating disk 16 of the thickness regulating plate 25, that is, outside, a coin passage 28 substantially tangential to the rotating disk 16 has a passage surface 28a formed on the lower edge portion of the outlet 26 of the thickness regulating plate 25. Are provided in a state in which they are matched.
A transport belt 29 is stretched over the passage surface 28a.

Then, the operator inserts coins on the upper surface 16a of the rotating disk 16 inside the annular guide 24 and the thickness regulating plate 25, and in this state, the motor 1
When 9 rotates the drive shaft 20, the rotation is transmitted via the gears 21 and 22, and the rotation shaft 15 and the rotating disk 16 are rotated.

Here, the rotating disk 16 is rotated in a direction in which coins are fed to the coin passage 28 (clockwise direction in FIG. 2; hereinafter, the rotating disk 16 and the motor 1 at this time).
9, the rotation direction of the drive shaft 20 is normal rotation, and the reverse direction is reverse rotation), the centrifugal force of the rotation causes the coin to move along the annular guide 24 which is the outer periphery thereof, and the thickness regulating plate 2
5, only one coin passes through the outlet 26 of coin 5 and the coin passage 2
It is fed out to 8. The coins fed out one by one in this manner are sequentially conveyed through the coin passage 28 by the conveyance belt 29.

Next, a control system of the coin supply device 11 will be described. A coin detecting means 31 for detecting coins fed out and conveyed from the rotating disk 16 is provided at an intermediate position of the coin passage 28 (see FIG. 3). As the coin detecting means 31, for example, an optical sensor including a light emitting element and a light receiving element for detecting a coin when the optical path is interrupted by a coin moving in the coin path 28 is adopted.

In the vicinity of the rotating disk 16, there is provided a residual coin detecting means 32 for detecting whether or not there is a coin remaining on the rotating disk 16. The residual coin detecting means 32 detects a coin by interrupting the optical path with at least one coin present on the rotating disk 16, for example, and moves the optical path horizontally so as to pass within the height range of one coin. An optical sensor or the like including a light emitting element and a light receiving element arranged in the same is employed.

The motor 19 drives the rotary disk 16, ie, the drive shaft 20, to rotate forward when a normal drive signal is input from the control unit 33, and rotates the rotary disk 16 when a reverse drive signal is input. 16 that drives the drive shaft 20 to rotate in the reverse direction, and further has a drive main unit 34 that stops driving the rotating disk 16, that is, the drive shaft 20 when no forward drive signal and reverse drive signal are input. In addition, a sensor including a disk-shaped member having slit holes formed at equal intervals and fixed to rotate integrally with the drive shaft 20, and a light emitting element and a light receiving element for detecting the presence or absence of the slit hole in the disk-shaped member And a rotary encoder (detection means) 35 for detecting the rotation speed of the drive shaft 20. Note that when the drive main unit 34 switches from a state where a forward drive signal or a reverse drive signal is input to a state where it is not input, the drive main unit 34 rotates the drive shaft 20 with its inertia force without braking.

In the first embodiment, when the control unit 33 rotates the rotary disk 16 forward from one stop to the next stop (hereinafter, this is referred to as one normal rotation of the rotary disk 16). ), A positive drive signal is sent to the drive main unit 34, as shown in FIG.
As shown, the output of the constant output time T ₁ and (ON) and stop certain stopping time T ₂ (OFF) is adapted to intermittently output so as to be alternately repeated. In this case, the output time T ₁ is set to be slightly shorter than the stopping time T _2. Thus, at one forward rotation,
By outputting the positive drive signal to the drive main unit 34 so that the output of the output time T ₁ and the stop of the stop time T ₂ are alternately repeated, the drive main signal is output as compared with the case where the positive drive signal is always output. The drive torque can be reduced without lowering the number of rotations of the unit 34 per unit time.

Also, when the control unit 33 reversely rotates the rotary disk 16 from one stop to the next stop (hereinafter, this is referred to as one reverse rotation of the rotary disk 16), the drive main unit 34 a drive signal, as shown in FIG. 4 (b), and stopping the constant stop time T ₄ outputs a constant output time T ₃ (oN) (oF
And F) are output intermittently so as to be alternately repeated. In this case, the output time T ₃ is equal to the stop time T ₄
It is set to be much longer. The first
In the embodiment, the output time T ₁ of the forward drive signal is shorter than the output time T ₃ of the reverse drive signal.

Further, the ratio T ₁ / T ₂ of the output time T ₁ for the stop time T ₂ of the forward drive signal is small relative to the rate T ₃ / T ₄ output time T ₃ for stop time T ₄ of the reverse drive signal Is set. By setting in this manner, the driving torque generated by the driving main unit 34 during the reverse rotation is made larger than that during the normal rotation, that is, the driving torque can be transmitted from the driving main unit 34 to the rotating disk 16 during the normal rotation. It is possible to make the necessary drive torque smaller than the drive torque that can be transmitted from the drive main part 34 to the rotating disk 16 during the reverse rotation without changing the number of rotations per unit time. In the first embodiment, the motor 19 and the gears 21 and 22 are
A driving unit 36 for rotating the rotating disk 16 forward and backward is configured.

Next, the contents of control relating to coin feeding processing by the control unit 33 of the first embodiment having the above-described configuration will be described below with reference to the flowchart shown in FIG. When the start operation of the coin feeding process is performed from the operation section (not illustrated), the driving portion 36 drive the main portion 34 in the forward drive signal to a predetermined output constant output time T ₁ as described above downtime T ₂ The rotation disk 16 is rotated intermittently so that the stop operation is alternately repeated (step SP).
At the same time as 1), a timer (not shown) is turned on to start counting the time t (step SP2).

As described above, when the rotating disk 16 rotates forward and coins are fed out to the coin passage 28, the state of the rotating speed of the rotating disk 16 is monitored from the detection signal from the rotary encoder 35, and the rotation speed is monitored. It is determined whether or not there is a rotation abnormality based on whether or not the rotation is equal to or less than a predetermined value (step SP3).

If the rotation speed of the rotary disk 16 is equal to or lower than the predetermined value in step SP3, it is determined that there is a rotation abnormality and a jam such as a jam of coins has occurred, and the drive main unit 34 is directly driven. signal completely stopped (OFF) the output (step SP4), then the reverse drive signal to the drive main portion 34 and the output of the constant output time T ₃ as described above and the stopping certain stopping time T ₄ is A jam clearing operation is performed in which the rotation disk 16 is intermittently output so as to be alternately repeated and reversely rotates the rotating disk 16 for a predetermined time (step SP5).

[0025] Each time performing the jam release processing operation in steps SP5, and adding the count C ₁ of a counter (not shown) from 1 by 1 are sequentially (step SP6), and a predetermined number of times C that predetermined this count C ₁ compared to (step SP7), the count C ₁ returns to step SP1 does not reach the predetermined number of times C. If the count C ₁ has reached the predetermined number C, it is determined that the jam has not been resolved, despite the fact that the jam clearing operation of step SP5 has been performed only the predetermined number C, and an alarm is generated in either voice or display. Then, the drive of the drive main unit 34 of the motor 19 is completely stopped (step SP8).

On the other hand, in step SP3, when it is determined that the rotational speed of the rotary disk 16 is at a level exceeding a predetermined value and there is no abnormal rotation, the coin detecting means 31 it is determined whether the coin of the coin passage 28 is detected (step SP9), if the coin has been detected, the timer count time t, the value of the count C ₁ and later counts C ₂ counter to 0 The timer is cleared (step SP10), and then the timer is turned on again to start timing (step SP11), and the process returns to step SP3.

In step SP9, if it is determined from the detection signal from the coin detecting means 31 that the coin detecting means 31 has not detected the coin in the coin passage 28, the timer time t is set to a predetermined time. determines whether reached T ₅ (step SP 12), if not reached the predetermined time T _5, with the flow returns to step SP3, when it reaches the predetermined time T _5, the feeding of the coin of the coin passage 28 It is determined that the operation has not been performed, the time count t of the timer is cleared to 0 (step SP13), and the output of the positive drive signal to the drive main unit 34 is completely stopped (OFF) (step SP14). a reverse drive signal to the drive main portion 34 intermittently is output to the output of the constant output time T ₃ and the stop fixed stopping time T ₄ are alternately repeated as described above, the rotation circle A jam clearing operation is performed to reversely rotate the board 16 for a predetermined time (step SP15).

Next, it is determined from the detection signal from the remaining coin detecting means 32 whether or not there is any remaining coin on the rotating disk 16 (step SP16). If no coin is detected by the remaining coin detecting means 32, the rotating disk 16 is detected. It is determined that there is no remaining coin, and the coin feeding process ends. On the other hand, step S
In P16, if the coins remaining coin detection means 32 is detected, it is determined that there is a residual coins rotating disk 16, the count C ₂ of a counter (not shown), the step SP
One from 1 per the order of performing the jam release processing operation 15 is added (step SP17), compares the predetermined number of times C that predetermined this count C ₂ (step S
P18), the count C ₂ returns to step SP1 does not reach the predetermined number of times C. Further, if the count C ₂ has reached the predetermined number C, despite was jam release processing operation in steps SP15 predetermined number of times C, as the jam persists, caused the alarm, driving the main portion of the motor 19 34 is completely stopped (step SP
8).

According to the coin processing machine described above, the control unit 33 outputs the positive drive signal so that the output and the stop of the positive drive signal are alternately repeated during one forward rotation of the rotating disk 16 (specifically, the control unit 33). , So that the output of the fixed output time T ₁ and the stop of the fixed stop time T ₂ are alternately repeated). By intermittently setting the stop time, the driving torque of the driving unit 36 can be reduced without lowering the rotation speed of the rotating disk 16. Accordingly, the driving torque that can be transmitted to the rotating disk 16 by the driving unit 36 during the forward rotation of the rotating disk 16 can be reduced. Therefore, when a coin jam occurs, the rotating speed is reduced and the rotating disk 16 is stopped in the worst case. Since the torque applied by the drive unit 36 is also reduced, each mechanism unit such as the drive unit 36 and the rotary disk 16 relating to the feeding of coins from the rotary disk 16 is not overloaded, and these damages can be prevented.

On the other hand, the ratio T ₃ / T ₄ output time T ₃ for stop time T ₄ of the reverse drive signal is large relative to the ratio T ₁ / T ₂ of the output time T ₁ for the stop time T ₂ of the positive drive signal When the rotating disk 16 is rotated in the reverse direction,
The drive torque that can be transmitted to the rotary disk 16 by the rotary disk 6 is increased, so that the rotary disk 16 can be rotated in the reverse direction even when a jam occurs. Therefore, the jam can be reliably eliminated. In addition, there is no need to provide a clutch or the like only to prevent damage to each mechanism when a jam occurs, so that the overall size is not increased. In addition, since the rotation speed of the rotating disk 16 is not reduced, the speed of coin feeding processing is not reduced.

The control unit 33 determines that the rotational speed of the drive shaft 20, that is, the rotational speed of the rotary disk 16 is reduced to a predetermined value or less by the rotary encoder 35 during one normal rotation for feeding out coins by the rotary disk 16. When it is detected, the output of the drive signal to the drive main unit 34 is completely stopped. Therefore, when a coin jam occurs, the drive unit 3
6 to stop the rotation of the rotating disk 16 in the forward rotation direction.

In addition, the drive main unit 34 drives the rotary disk 16 to rotate in the reverse direction when the reverse drive signal is input, and stops driving the rotary disk 16 when the reverse drive signal is not input. When the rotary encoder 35 detects that the rotation speed of the rotary disk 16 has become equal to or less than a predetermined value during one forward rotation of the rotary disk 16, the control unit 33 performs the above-described operation. Rotating disk 16
After stopping the driving of the normal rotation direction, the reverse drive signal to the drive main portion 34, intermittently to the output of the constant output time T ₃ and the stop fixed stopping time T ₄ are alternately repeated Therefore, if the rotation of the rotating disk 16 in the forward rotation direction is stopped when a jam of a coin occurs, the rotating disk 16 is automatically rotated in the reverse direction, and jams such as jammed coins are caused. Will be resolved. Therefore, it is possible to automatically eliminate a jam such as a jam of coins at the time of occurrence.

In the first embodiment described above,
When to output the reverse drive signal during reverse rotation of the primary, without providing the stop time T _4, it may be continuously output. Also in this case, the ratio T ₃ / T ₄ of the output time T ₃ to the stop time T ₄ is infinite, so that the ratio T ₁ / T ₂ of the output time T ₁ to the stop time T ₂ is set smaller. Will be. Even with this setting, it is possible to increase the drive torque of the drive unit 36 during the reverse rotation as compared with that during the forward rotation without changing the number of rotations per unit time.

Next, a second embodiment of the present invention will be described with reference to FIGS.
With reference to FIG. 9, only differences from the first embodiment will be described below. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. A rotating shaft 15 is rotatably supported around a vertical axis via bearings 13 and 14 of the same diameter on a supporting member 12 fixed to an unillustrated machine side of the coin processing machine. The rotating disk 16 is mounted on the rotating disk 16 via the bearing 40.
Are fixed to the rotating shaft 15.

A pulley 42 is provided on the upper side below the rotating shaft 15.
Are fixed coaxially, and a pulley 44 is coaxially supported on the lower side via a one-way clutch 43. On the drive shaft 20 of the motor 19, a pulley 46 is fixed on the upper side so as to be coaxial with the pulley 42, and a pulley 47 is coaxial and fixed on the lower side with the pulley 44. Is fixed. Here, all the pulleys 42, 44, 46, and 47 have the same outer diameter and the same outer peripheral portion, and as shown in FIG.
A pair of conical surfaces 49 and 5 that are inclined in the opposite directions at the same angle with respect to the axis in the center predetermined range in the axial direction of the outer peripheral portion.
A V-shaped groove portion 51 is formed on the entire circumference by disposing 0 near the small diameter side (only pulleys 46 and 47 on the drive shaft 20 side are shown in FIG. 7).

Then, the upper pulley 42 and the pulley 4
A round belt 53 having the same circular cross section orthogonal to its length direction over the entire length is wound around 6. On the other hand, a V-belt 54 having an isosceles trapezoidal shape having the same cross section orthogonal to the length direction over the entire length is wound around the lower pulley 44 and the pulley 47 with the small width side disposed inside. I have. In this state, the V belt 54
The inclined two-sided portions 55 and 56 are in surface contact with the groove portion 51, so that the contact area between the pulley 44 and the pulley 47 is larger than the contact area between the round belt 53 and the pulley 42 and the pulley 46 which is almost in line contact. Has become.

Here, the one-way clutch 43 is connected to the pulley 47 when the motor 19 rotates the drive shaft 20 forward.
Without transmitting the rotational force transmitted through the V-belt 54 and the pulley 44 in this direction to the rotary shaft 15,
When the drive shaft 20 is rotated in the reverse direction, the rotational force transmitted through the pulley 47, the V-belt 54, and the pulley 44 in this direction is transmitted to the rotary shaft 15.

In the second embodiment, the control unit 33 sends a positive drive signal to the motor 19 during one forward rotation and one reverse rotation of the rotating disk 16.
It is designed to output continuously so as not to stop. The motor 19 drives the rotating disk 16, that is, the drive shaft 20 to rotate forward when the forward driving signal is input from the controller 33, and rotates the rotating disk 16 when the reverse driving signal is input. That is, the drive shaft 20 is driven to rotate in the reverse direction, and further, the drive to the rotating disk 16, that is, the drive shaft 20 is stopped when the normal drive signal and the reverse drive signal are not input, and a rotary encoder is provided. It has not been done (see FIG. 8).

With this configuration, the rotating disk 16
In one forward rotation, the one-way clutch 43
However, the torque transmitted from the motor 19 via the pulley 47, the V-belt 54 and the pulley 44 is not transmitted to the rotating shaft 15, so that the pulley 46, the round belt 53
The rotating shaft 15, that is, the rotating disk 16 is rotated only by the rotating force transmitted through the pulley 42.
The pulley 46 and the round belt 53 having such a small contact area and a small coefficient of friction (that is, easy to cause slip).
Since the driving torque of the motor 19 is transmitted to the rotary disk 16 by the pulley 42 and the driving torque becomes a relatively small predetermined value, the round belt 53 slides on the pulley 46 or the pulley 42, and the round belt 53 further slides. Transmission of the driving torque of the motor. Therefore, the driving torque that can be transmitted to the rotating disk 16 by the driving unit 36 during the forward rotation of the rotating disk 16 can be reduced.

On the other hand, during one reverse rotation of the rotating disk 16, the one-way clutch 43 transmits the rotating force transmitted from the motor 19 via the pulley 47, the V-belt 54 and the pulley 44 to the rotating shaft 15. become. Therefore, the rotational force transmitted via the pulley 46, the round belt 53 and the pulley 42, and the rotational force transmitted via the pulley 47, the V belt 54 and the pulley 44,
5, that is, the rotating disk 16 rotates. When the pulley 47, the V-belt 54 and the pulley 44 are combined with the pulley 46, the round belt 53 and the pulley 42, that is, the contact area is large and the friction coefficient is large (that is, the slip is unlikely to occur). Since the drive torque of No. 19 is transmitted to the rotating disk 16,
Until the driving torque is significantly larger than the predetermined value, the V belt 54 and the round belt 53
A larger driving torque can be transmitted to the rotating disk 16 without causing a slip on the pulley 47 or the pulleys 42 and 46, or without causing a slip even if the maximum possible driving torque is applied.

In the second embodiment, the motor 19, pulleys 42 and 46, round belt 53, pulley 4
4, 47, V-belt 54 and one-way clutch 43
Constitutes a drive unit 36 for rotating the rotating disk 16 in the forward and reverse directions, and the pulleys 42 and 46, the round belt 53, the pulleys 44 and 47, the V belt 54, and the one-way clutch 43 rotate the rotating disk 16 in the forward direction. At the time, when a predetermined driving torque smaller than the driving torque that can be transmitted to the rotating disk 16 at the time of the reverse rotation is generated between the rotating disk 16 and the rotating disk 16, a slip is generated, and the driving torque of the rotating disk 16 is further increased. A transmission preventing means 58 for preventing transmission is provided.

Next, control contents relating to coin feeding processing by the control unit 33 of the second embodiment having the above-described configuration will be described below with reference to a flowchart shown in FIG. When a coin feeding process is started from an operation unit (not shown), the motor 19 of the drive unit 36 continuously outputs a positive drive signal to rotate the rotary disk 16 forward (step SP21). The timer is turned on to start measuring the time t (step SP22).

Next, it is determined from the detection signal from the coin detecting means 31 whether the coin detecting means 31 has detected a coin in the coin passage 28 (step SP23). the measured time t, the value of the count C ₂ of the counter is cleared to 0 (step SP24),
Thereafter, the timer is turned on again to start timing (step SP25), and the process returns to step SP23.

In step SP23, when it is determined from the detection signal from the coin detecting means 31 that the coin detecting means 31 has not detected a coin in the coin passage 28, the timer time t is set to a predetermined time. T ₅
Determines whether reached (step SP26), if not reached the predetermined time T _5, with the flow returns to step SP23, when it reaches the predetermined time T _5, the coin of the coin passage 2
8 is determined not to have been executed, the timer time t of the timer is cleared to 0 (step SP27), and the output of the positive drive signal to the motor 19 is completely stopped (OFF) (step SP28). Thereafter, a jam release processing operation of continuously outputting the reverse drive signal to the motor 19 and reversely rotating the rotating disk 16 for a predetermined time is performed (step SP29).

Next, it is determined from the detection signal from the remaining coin detecting means 32 whether or not there is any remaining coin on the rotating disk 16 (step SP30). If no coin is detected by the remaining coin detecting means 32, the rotating disk 16 is detected. It is determined that there is no remaining coin, and the coin feeding process ends. On the other hand, step S
In P30, if the coins remaining coin detection means 32 is detected, it is determined that there is a residual coins rotating disk 16, the count C ₂ of a counter (not shown), the step SP
1 by adding 1 in order for each to perform the jam release processing operation 29 (step SP31), compares the predetermined number of times C that predetermined this count C ₂ (step S
P32), the count C ₂ returns to step SP21 does not reach the predetermined number of times C. Further, if the count C ₂ has reached the predetermined number C, despite was jam release processing operation in steps SP29 predetermined number of times C, as the jam persists, caused the alarm, the motor 19
Is completely stopped (step SP33).

According to the coin processing machine described above, the pulleys 42 and 46 and the round belt 53 of the drive unit 36 for transmitting the rotation during one normal rotation of the rotating disk 16 generate the predetermined driving torque by the rotating disk 16. In this case, a slip is generated to prevent transmission of further driving torque to the rotating disk 16, and the driving torque to the rotating disk 16 can be reduced. Therefore, as in the first embodiment,
When a jam of coins occurs, the torque applied by the drive unit 36 to the rotating disk 16 whose rotation speed is reduced and the worst stop occurs is also reduced, so that the driving unit 36 and the rotating disk 16 relating to the feeding of coins of the rotating disk 16 etc. No overload is applied to each of the mechanism parts, and the damage can be prevented.

When the rotating disk 16 is rotating in the reverse direction, the pulley 4 of the driving unit 36 for transmitting the rotation at this time is used.
6. Since the round belt 53 and the pulley 42 and the pulley 47, the V-belt 54 and the pulley 44 can transmit a driving torque that greatly exceeds the predetermined driving torque due to an increase in their contact area, the rotating disk 16 The driving torque to the motor can be increased. Therefore, even when a jam occurs, the rotating disk 16 can be rotated in the reverse direction, so that the jam can be reliably eliminated. In addition, since the rotation speed of the rotating disk 16 is not reduced, the speed of coin feeding processing is not reduced.

In the second embodiment, the pulleys 42, 4 when the rotary disk 16 rotates forward are mainly used.
6 and the round belt 53, and the difference between the contact area of the pulleys 42, 46 and the pulleys 44, 47 and the V-belt 54 added to the round belt 53 when the rotating disk 16 rotates in the reverse direction. 16 has been described as an example in which the driving torque that can be transmitted to the rotating disk 16 during the reverse rotation is smaller than the driving torque that can be transmitted to the rotating disk 16, but the material and shape of the contact portion are not limited to the contact area.
Alternatively, an appropriate combination of the contact area, material, shape, and the like can be used.

The pulleys 44 and 47 and the V belt 5
As shown in FIG. 10, instead of the pulley 42, a gear 60 is provided below the pulley 42 of the rotating shaft 15 via a one-way clutch 43.
Are coaxially supported, and a gear 6 having the same number of teeth as the gear 60 is provided below the pulley 46 of the drive shaft 20 of the motor 19.
The gear 1 is coaxial and fixed at the same height as the gear 60, and a gear 62 always meshing with the gears 60 and 61 is rotatably fixed at a fixed position on the machine body (not shown) by a support shaft 63. It is also possible to support as described above (third embodiment).

With this configuration, the rotating disk 16
In one forward rotation, the one-way clutch 43
Does not transmit the rotational force transmitted from the motor 19 via the gears 61, 62, 60 to the rotating shaft 15, and therefore, as in the second embodiment, the pulley 46, the round belt 53, and the pulley 42 , The rotating shaft 15, that is, the rotating disk 16 is rotated only by the rotating force transmitted through the rotating shaft 15.

On the other hand, during one reverse rotation of the rotating disk 16, the one-way clutch 43 applies the rotating force transmitted from the motor 19 via the gears 61, 62, 60 to the rotating shaft 1.
5, the rotation transmitted through the pulley 46, the round belt 53, and the pulley 42;
The rotation transmitted through the gears 61, 62, and 60 causes the rotation shaft 15, that is, the rotation disk 16 to rotate.
In this case, the motor 19, the pulleys 42 and 46, the round belt 53, the gears 60 to 62, and the one-way clutch 4
3 constitutes the drive unit 36, and the pulleys 42 and 46, the round belt 53, the gears 60 to 62 and the one-way clutch 43 constitute the transmission preventing means 58.

Therefore, similarly to the first embodiment, when the rotating disk 16 rotates forward, a predetermined driving torque smaller than the driving torque that can be transmitted to the rotating disk 16 during reverse rotation is applied to the rotating disk 16. When this occurs, a slip can be generated between the rotating disk 16 and the same effect as in the second embodiment can be obtained. in addition,
When the rotating disk 16 rotates in the reverse direction, the gears 61, 62, 6
0 and the one-way clutch 43 cause the driving force of the motor 19 to rotate without causing the rotation of the rotating shaft 15, that is, the rotating disk 1.
6, the rotating disk 16 can be reversely rotated with a driving torque as large as possible in a state where a jam has occurred, so that the jam can be more reliably eliminated.

Further, pulleys 44 and 47, V belt 5
4. Instead of the pulleys 42 and 46 and the round belt 53, as shown in FIG. 11, a gear 64 is coaxially supported by the rotating shaft 15 via a one-way clutch 43, and a torque limiter 65 is provided below the gear 64. At the same time, the drive shaft 20 of the motor 19 is mounted on the torque limiter 65, and the gear 66 having the same number of teeth as the gear 64 is fixed to the drive shaft 20 coaxially. And a gear 67 having the same number of teeth
A gear 68 having the same number of teeth as the gear 66 always meshing with the gear 6 can be rotatably supported at a fixed position on the machine body (not shown) on the other end side (fourth). Embodiment).

In this case, when the driving torque transmitted from the driving shaft 20 to the rotating shaft 15 via the torque limiter 65 becomes a relatively small predetermined value, the torque limiter 65 slips by itself and further increases the driving torque. To the rotating shaft 15 is prevented. And the one-way clutch 43
When the motor 19 rotates the drive shaft 20 forward, the gear 6
6, 68, 67, 64, the drive shaft 19 of the motor 19
When the motor 19 rotates the drive shaft 20 in the reverse direction, the rotational force of the gear 64 transmitted from the motor 19 is not transmitted to the rotary shaft 15. The rotation force transmitted from the drive shaft 20 is transmitted to the rotation shaft 15. In this case, the motor 19, the torque limiter 65, the gears 64, 66 to 68, and the one-way clutch 43 constitute the drive unit 36, and the torque limiter 65, the gears 64, 66 to 68, and the one-way clutch 43 constitute the transmission preventing means. 58.

With this configuration, the rotating disk 16
In the first normal rotation, when the driving torque is smaller than the predetermined value, the rotating shaft 15, that is, the rotating disk 16 is rotated by the driving torque transmitted from the driving shaft 20 of the motor 19 via the torque limiter 65. Will be. Then, when the drive torque reaches the above-mentioned predetermined value, the torque limiter 65 slides by itself, and prevents transmission of further drive torque to the rotating shaft 15. Therefore, the driving torque that can be transmitted to the rotating disk 16 by the driving unit 36 during the forward rotation of the rotating disk 16 can be reduced.

On the other hand, during one reverse rotation of the rotating disk 16, even if the torque limiter 65 exceeds the value at which slippage occurs, the one-way clutch 43 is operated by the gears 66, 68, 6.
The rotational force transmitted through the rotation shafts 7 and 64 is transmitted to the rotation shaft 15. Therefore, a larger driving torque can be transmitted to the rotating disk 16.

Therefore, similarly to the second embodiment, when the rotating disk 16 rotates forward, a predetermined driving torque smaller than the driving torque that can be transmitted to the rotating disk 16 during reverse rotation is applied to the rotating disk 16. When this occurs, a slip can be generated between the rotating disk 16 and the same effect as in the second embodiment can be obtained. in addition,
When the rotating disk 16 rotates in the reverse direction, the gears 64, 66 to 6
8 and the one-way clutch 43 allow the driving force of the motor 19 to rotate without causing the rotation of the rotating shaft 15, that is, the rotating disk 1.
6, the rotating disk 16 can be reversely rotated with a driving torque as large as possible in a state where a jam has occurred, so that the jam can be more reliably eliminated.
