[0002]
[Prior art]
The conventional technology will be described with reference to FIGS. FIG. 3 is a longitudinal sectional view of a conventional coin discharge device. 4 is a BB-BB arrow view when a hopper case described later in FIG. 3 is removed.
[0003]
In the figure, a conventional coin discharge device 101 includes a hopper case 109 for storing coins, and an opening 106 that is disposed on a hopper base upper surface plate portion 102A and rotates in a horizontal plane (or in an inclined plane). A carrying disk 107. Two gate pins 103 project from the hopper base upper surface plate portion 102A. A groove (not shown) in the bottom of the carrying disc 107 is machined so as not to interfere with the gate pin 103.
[0004]
The coins stored in the opening 106 of the carrying disk 107 are rotated in a horizontal plane by the carrying disk 107, hit the gate pin 103, the direction is regulated, and the coin is discharged from the hopper case 109 in a predetermined direction. The rotation of the carrying disk 107 is given by the motor 105 via the gear head 104. On the surface of the carrying disc 107 on the hopper case 109 side, a jam release jig insertion hole 107A is formed.
[0005]
In this coin discharge device 101, coins in the opening 106 of the carrying disc 107 may be sandwiched between the gate pin 103 and the carrying disc 107, and as a result, the carrying desk 107 cannot be rotated. The so-called coin biting phenomenon sometimes occurred. If this bite occurs, the coin bite state can be changed by inserting the claw 120A (see FIG. 5) of the jam release jig 120 into the jam release jig insertion hole 107A and reversing the carrying desk 107. It can be canceled.

When a coin is bitten, a driver (jig) is inserted into the driver insertion slot 221A, and the release roller 221 is forced in the direction of the arrow shown in FIG. 6 (the direction opposite to the biting direction). It was also performed to release the coin bite.
[0007]
[Problems to be solved by the invention]
In the conventional technology as described above, a jig for releasing the coin biting is required, and the jig may be lost. In addition, since it is physically possible to rotate the carrying desk in the biting direction, force is further easily applied in the biting direction, and the biting is strengthened and the biting release operation becomes difficult. was there.
[0008]
According to the method using the jam releasing jig of the prior art, in order to perform the biting release operation, it is necessary to take out all the coins in the hopper case, and the biting release operation takes time. It is complicated. In some cases, coins were lost while coins were being taken out.
[0009]
Therefore, the invention of the present application can easily remove the bite of the coin without removing the coin from the hopper case, simplify the bite release operation, or can reliably release the bite without using a jig or the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a longitudinal sectional view of a coin discharging device according to the present invention, and FIG. 2 is an enlarged view taken along the line AA-AA in FIG. 1 of the coin discharging device with a hopper case removed.
[0016]
The coin discharging device 1 has a hopper base 2 that supports the entire coin discharging device 1, and a gate pin for discharging the coins after separating the coins from the coin discharging device 1 to the hopper base upper surface plate portion 2A. 3 is attached by being urged from the bottom to the top in the longitudinal direction of the gate pin 3 by a leaf spring (not shown). A motor 5 as a drive source of the present invention having an output shaft on both sides is attached to the hopper base 2 via a gear head 4.
[0017]
The configuration around the motor 5 will be described with reference to FIG. The motor shaft 5A passing through the rotor 5D of the motor 5 has two shaft end portions 5B and 5C, and one of the two shaft end portions 5B and 5C has a shaft end portion 5C for reducing the rotation speed. The shaft end 4E of the input shaft 4C of the high speed gear 4A of the gear head 4 is connected by a coupling 21, and the hopper base upper surface plate 2A is connected to the shaft end 4H of the output shaft 4D of the low speed gear 4B of the gear head 4. The shaft end 7B of the rotating shaft 7A of the disc-shaped carrying disk 7 that penetrates (see FIG. 1) is connected by a coupling 22.
[0018]
Here, the driving force transmitting member of the present invention includes a motor shaft 5A, a high speed gear 4A, an input shaft 4C, a low speed gear 4B, an output shaft 4D, a rotating shaft 7A, a shaft end portion 5C and a shaft end portion of the motor 5 of both shafts. 4E is a coupling 21 that connects 4E, and a coupling 22 that connects the shaft end 4H and the shaft end 7B. The rotor 5D and the carrying disk 7 of the motor 5 do not correspond to the driving force transmission member.
[0019]
The shaft end portion 5B, the shaft end portion 4F, and the shaft end portion 4G are shafts in which driving force is not transmitted from other driving force transmitting members during normal operation, or driving force is not transmitted to other driving force transmitting members during normal operation. It is an end and corresponds to the free end of the driving force transmission member. Further, the driving force is transmitted to the free end portion of the driving force transmitting member from the shaft end portion 5C and the shaft end portion 4H that transmit the driving force to the other driving force transmitting member during the normal operation, or the other driving force transmitting member. The high-speed gear free end 4I without the shaft end 4E and the shaft end 7B, and the low-speed gear free end 4J are included.
[0020]
The carrying disk 7 is formed with one or more apertures 6 that accept coins one by one. The carrying disk 7 guides the received coins by rotating them toward the gate pins 3 by rotation. The openings 6 are provided on a pitch circle concentric with the rotation center of the carrying disk 7 and have a circular shape. A coin passage (not shown) is formed in the inner wall of the hollow cylinder formed in the carrying disk 7 as an opening 6 in the vicinity of the outer periphery of the carringe disk 7.
[0021]
Although the outer periphery of the carrying disk 7 is the same regardless of the denomination, the carrying disk 7 is classified into three types according to the size of the opening 6. That is, as shown in FIG. 2 for a small size in which four openings for 1 yen and 50 yen are formed, for example, and for a middle size in which four openings for 5 yen, 10 yen and 100 yen are formed, for example, 500 yen For example, it is classified into a large size in which three openings are formed.
[0022]
A jam release knob 8 is attached to the shaft end portion 5B of the motor shaft 5A described above via a one-way clutch 8A that transmits a driving force only in either the clockwise direction or the counterclockwise direction. By rotating the jam release knob 8, a rotational torque for releasing the biting of coins as a second driving force of the present invention can be applied manually. When the one-way clutch 8A is rotated in the same direction as the normal rotation direction of the carrying disk, the one-way clutch 8A rotates idle, and when it is rotated in the opposite direction, the rotational force of the jam release knob 8 is transmitted to the motor shaft. Is attached. Instead of a knob provided with a one-way clutch, a tool having a ratchet mechanism may be used instead.
[0023]
The jam release knob 8 may be attached to the shaft end 4F of the input shaft 4C of the high speed gear 4A or the shaft end 4G of the output shaft 4D of the low speed gear 4B instead of the shaft end 5B of the motor shaft 5A.
[0024]
A hopper case 9 for storing coins is attached to the upper surface of the hopper base upper surface plate portion 2A. An exit opening 9B for discharging coins is formed on the side surface near the bottom of the hopper case 9. A coin guide 10 for restricting the width of the outlet opening 9B of the hopper case is attached to the hopper base upper surface plate portion 2A.
[0025]
The coin guide 10 is a substantially trapezoidal plate shape that regulates the width of the outlet opening 9B of the hopper case 9 corresponding to the size of the coin, and the size and shape differ for each denomination. The structure is such that the movement of the coins to be released is regulated so as to keep the urging force of the spring 11 substantially constant so that the amount of expansion of the spring 11 due to the rotation of the roller 12 is constant.
[0026]
The hopper base upper surface plate portion 2A is rotatably attached with a link 13 provided at one end with a feed roller 12 for restricting the coin release and repelling the coin. One end 11A of a spring 11 (pulling coil spring) (indicated by a two-dot chain line in FIG. 2) for biasing the feeding roller 12 is at the tip 13A of the link 13, and the other end 11B of the spring 11 is at the hopper base upper surface plate portion 2A. Suspended by. The link 13 has a substantially “<” shape. The pin 13 </ b> C penetrates the center of the bent portion, and the pin 13 </ b> C is the center of rotation of the delivery roller 12. A feed roller 12 is rotatably attached to a tip 13B opposite to the tip 13A to which one end 11A of the spring 11 of the link 13 is coupled.
[0027]
The delivery roller 12, the link 13, and the spring 11 are common to all denominations. The hopper base 2 is provided with a discharge chute 14 for guiding coins outside the apparatus.
[0028]
Near the inlet opening 9A of the hopper case 9, a pair of full sensors 15A and full sensors 15B for detecting the full state of coins (only the elements are shown in FIG. 1 and lead wires and terminals are omitted. Is attached across the coin storage space of the hopper case 9. One of the full sensor 15A and the full sensor 15B is a transmitter and the other is a receiver. Further, one of the full sensor 15A and the full sensor 15B may be a light emitter and the other may be a light receiver. Since the line connecting the full sensor 15A and the full sensor 15B is located above the hopper case 9, the coins are full when the full sensors 15A and 15B detect the coins.
[0029]
A pair of near full sensor 16A and near full sensor 16B for detecting a full coin notice are attached to the middle of the inlet opening 9A and the bottom of the hopper case 9 with the coin storage space of the hopper case 9 interposed therebetween. Since the line connecting the near sensor 16A and the near sensor 16B is located in the middle of the inlet opening 9A and the bottom of the hopper case 9, the coins are almost full when the near sensors 16A and 16B detect the coin.
[0030]
In the hopper case 9, a near-end sensor 17 </ b> A (only one of the pair is shown in FIG. 1) for detecting that the remaining amount of coins in the hopper case 9 is small is located near the bottom of the carrying disk 7. It is mounted parallel to the surface. Since the line connecting the near-end sensors is close to the bottom of the hopper case, when the near-end sensor does not detect coins, the remaining amount of coins is low. Counting sensors 18A, 18B, 19A, and 19B for counting the number of coins are attached to the discharge chute 14.
[0031]
Next, the operation of the present embodiment will be described. The coins stored in the hopper case 9 are stored one by one in the opening 6 formed in the carrying disk 7. The rotation of the motor 5 generates a rotational torque as the first driving force of the present invention, and this rotational torque is transmitted to the carrying disk 7 via the gear head 4 so that the carrying disk 7 rotates. When the carrying disk 7 rotates, the coin is pushed by the wall portion of the opening 6, so that the coin moves while being guided by the carrying disk 7. The coin guided and moved by the carrying disk 7 contacts the gate pin 3 and is pushed out in the direction of the outlet opening 9B through a passage formed in the inner wall of the opening 6.
[0032]
The gate pin 3 attached through the hopper base upper surface plate portion 2A is in a state of protruding upward from the bottom portion of the carrying disk 7 due to a downward biasing force by a leaf spring. The bottom portion opening 6 of carrying the disc 7 is not present so as not to interfere with the gate pin 3, grooves (not shown) is processed. When a coin is pinched between the gate pin 3 and the bottom of the carrying disk 7, the gate pin 3 overcomes the urging force of the leaf spring, the gate pin sinks, and the bite is easily eliminated.
[0033]
The coin pushed out in the direction of the outlet opening 9B collides with the delivery roller 12, and rotates the delivery roller 12 and the link 13 coupled to the delivery roller 12 against the urging force of the spring 11, and the coin is repelled outside the apparatus. To be released. Therefore, when the opening 6 storing the coin comes to the position of the karate pin 3 due to the rotation of the carrying disc 7, the coin abuts against the gate pin 3 and is pushed out from the passage formed in the inner wall of the carrying disc 7. At this time, coins are detected by shielding the counting sensors 18A, 18B, 19A, and 19B, and the coins are confirmed to be released.
[0034]
The full sensors 15A and 15B detect and output that the coins stored in the hopper case 9 are full. The near full sensors 16A and 16B detect and output that the coins stored in the hopper case 9 are almost full. The near-end sensor 17A cooperates with the other near-end sensor (not shown) to detect and output that there are only a few coins stored in the hopper case 9. When coins are caught between the carrying disk 7 and the hopper base upper surface plate portion 2A, the rotation of the carrying disk, that is, the rotation of the motor 5 is inhibited, so that the current value increases and an abnormal current flows.
[0035]
Therefore, when an abnormal current flows through the motor 5, it is determined that a coin is caught between the carrying disk 7 and the hopper base upper surface plate portion 2A. At this time, the polarity of the motor 5 is changed, and the carrying disk 7 is rotated in the reverse direction to try to release the bite. That is, the motor 5 is rotated in the reverse direction for a certain time. After a certain period of time, the polarity of the motor 5 is further changed to perform normal rotation.
[0036]
If an abnormal current is detected at this time, it is determined that the biting has not been released, and the biting is released again. The number of cancellation attempts can be arbitrarily set. Even after trying to release the biting any number of times, an abnormal current is detected, and if it is determined that the biting state has occurred, an error signal is output and the rotation of the motor 5 is stopped. Then, in order to release the bite by human power, the jam release knob 8 is rotated in a predetermined direction, that is, a direction opposite to the rotation direction in the coin separation operation.
[0037]
This rotational force is transmitted to the carrying disc 7 via the motor shaft 5A and the gear head 4, and the carrying disc 7 rotates in the coin releasing direction, so that the coin between the hopper base upper surface plate portion 2A and the carrying disc 7 is moved. Biting can be removed. If it is rotated in the reverse direction by mistake, the jam release knob 8 is idled by the one-way clutch 8A, and the rotational force is not transmitted to the motor shaft 5A, the gear head 4 and the carrying disk 7. Therefore, the carrying disk 7 does not rotate in the direction opposite to the coin biting release direction, and does not deepen the coin biting.
[0038]
Here, “the second driving force can be transmitted to the driving shaft via the free end portion of the driving force transmitting member disposed from the first driving force generating portion to the carrier disk” means “the first driving force This means that the second driving force can be transmitted to the driving shaft from outside the driving force transmission path from the generator to the carrier disk. The “driving force transmission path” means a path along which transmission of driving force such as torque follows from a first driving force generation unit, for example, a rotor of a motor to a carrying disk.
[0039]
Therefore, “from the outside of the driving force transmission path” means a driving force transmission member that is directly involved in the function of transmitting the first driving force to the driving shaft coupled with one shaft end at the rotation center of the carrying disk. And other than the part that transmits the driving force to the other driving force transmission member, or the part other than the part that transmits the driving force from the other driving force transmission member. . Even a portion of a driving force transmission member that does not correspond includes an end portion to which a portion of the corresponding driving force transmission member is attached. This relationship will be described with reference to FIG. 7 as an example. The hatched portion is the driving force transmission path, and the blacked out portion is outside the driving force transmission path.
[0040]
【The invention's effect】
Without removing the coin from the hopper case, it can be rotated in the direction to release the biting of the carrying disk to release the bite of the coin. Since it is possible to apply a force to rotate the carrying disk through the free end of the driving force transmission member from the drive source to the carrying disk, even when a coin discharge device is installed in a limited space Not only can the coin bite be released, but access is facilitated, so that the coin bite can be released without using a jig.
[0041]
Further, if the second driving force can be applied only in the direction in which the biting is released, when the biting of the coin is released, the carrying disk is erroneously rotated in the biting direction, and the biting is performed. It is possible to perform a reliable release work without deepening. Also, coins can be managed reliably without accidentally releasing coins.
