Description

The present invention relates to a coin transport device that transports and releases coins that are sent one by one to a predetermined position, and a coin payout device that transports and discharges coins stacked one by one to a predetermined position. . Specifically, the present invention relates to a coin transport device and a coin payout device that are preferably used when processing a plurality of types of coins having different diameters.
Note that “coin” used in the present specification includes coins as currency, substitute money such as medals and tokens of game machines, and the like.

  There are several types of coins with different diameters, and various types of so-called size-free devices that can handle these types of coins (ie, multiple denominations) have been proposed in the past. Yes. For example, there are coin hopper devices disclosed in Patent Literature 1 and Patent Literature 2 for coin feeding devices that separate and send coins in a stacked state one by one.

  In the devices disclosed in Patent Document 1 and Patent Document 2, a circular support shelf that protrudes in the center of the rotating disk is arranged on the upper surface of the rotating disk that is inclined upward, and the coins are locked radially from the supporting shelf side. The coin is pushed by the coin locking body while being supported by the support shelf, and is sent out in the circumferential direction of the rotating disk by the coin receiving means arranged at a predetermined position. Patent Document 3 discloses an improved version of the coin hopper device of Patent Document 2.

  On the other hand, there are cases in which coins sent out from a coin sending device are transported to a predetermined position in a change machine, a vending machine, a game machine, etc. For example, Patent Document 4 discloses a coin sending method having a coin guide passage called an escalator. An apparatus is disclosed. Patent Document 5 discloses a coin lifting device using a spiral body (also referred to as a screw), and the coin lifting device also supports a plurality of denominations.

  However, in the apparatus disclosed in Patent Document 4, since the coins in the escalator are conveyed while the lower coins push the upper coins in an aligned state, they cannot cope with denominations having different diameters. That is, the inner dimension of the coin passage formed in the escalator must be adapted to the denomination to be conveyed, and the range of the coin diameter to be adapted is small. For example, even when trying to transport a coin with a small diameter relative to the inner dimension of the coin path, the coin cannot be properly aligned in the escalator and becomes zigzag-shaped, increasing the frictional resistance during transport and increasing the stability of the coin. Transport and release is difficult. Also, when coins with different thicknesses are mixed even if the diameter is the same, the thickness of the coin path is set corresponding to the coin with the maximum thickness, so in the case of thin coins, the movement range in the thickness direction is large, The upper end of the upper coin cannot be pushed up by the upper end of the lower coin, and the upper end and the lower end overlap with each other, so that the coin cannot be moved in the coin path, so-called coin clogging occurs.

  Furthermore, in the apparatus of Patent Document 4, since coins cannot be conveyed unless there are coins in the hopper and escalator, the coins remain in the hopper and escalator, and the escalator is configured to remove the remaining coins. There is also a problem that the cover plate to be removed must be removed. Techniques for solving this problem have been proposed in the past. For example, in a coin delivery device disclosed in Patent Document 6, an open / close gate is provided on the side wall of a coin passage, and a hopper and a gate are provided via an open gate. Coins remaining in the escalator are discharged to the collection port.

  In the improved apparatus of Patent Document 6, since the coins remaining in the hopper and the escalator are discharged to the collection port, there is a problem that all the coins inserted into the hopper cannot be conveyed to a predetermined position. In other words, in order to transport a predetermined number of coins to a predetermined position, it is necessary to insert extra coins into the hopper in consideration of the number of remaining coins (that is, the number of coins to be ejected). Furthermore, there is a need for a collecting device for collecting the remaining coins, and there is a problem that the size of the device is increased to provide a collecting port.

  In the apparatus disclosed in Patent Document 5, although it is easy to cope with denominations having different diameters or thicknesses, the larger the coin diameter, the easier the outer peripheral surface of the coin is detached from the outer peripheral surface of the spiral body, and the larger diameter coin In this case, a coin is caught between the spiral body and the guide passage, and so-called biting occurs. Therefore, in reality, it is necessary to exchange the spiral body in accordance with the coin diameter, and there is a problem that the diameter range that can be handled is insufficient. Furthermore, since the spiral body slides the coin, there is a problem that it is easy to wear and the durability is inferior.

  Therefore, there is a demand for a new coin transport device that can handle coins of various denominations that have a wide range of coin diameters or thicknesses that can be handled, and that is compatible with size free. If this new coin transport device is realized, for example, a coin payout device compatible with size free can be realized by combining with the coin delivery device of Patent Document 2.

  By the way, the coin transport distance by the coin transport device varies depending on the device to which it is applied. In particular, a large game machine may transport coins to a height of 2 meters or more. As described above, in the apparatus of Patent Document 4, since the lower coin in the escalator is conveyed by pushing the upper coin, the weight of all coins in the escalator is added to the lowest coin. Therefore, as the transport distance increases, the number of coins in the escalator also increases, and a great driving force is required to move the lowest-order coin. Although it is possible to transport to a certain height if a high output driving device is used, there is a problem that the height is limited and it is difficult to obtain a desired transport distance. Furthermore, since a great load is applied to the driving device, there is a problem that durability is lowered.

  Further, in the device of Patent Document 5, the length of the spiral body in the rotation axis direction is set according to the coin transport distance, but when the transport distance is long, for example, exceeding 50 cm, the entire spiral body is integrated. If it forms, it will become difficult to ensure processing accuracy, and a manufacturing cost will also increase. Therefore, a method of configuring a spiral by connecting a plurality of spiral members manufactured in a predetermined length in series in the direction of the rotation axis can be considered. However, when a spiral body having a configuration in which a plurality of spiral body members are connected in series is used, slight gaps or steps in the connection portion of the spiral body member are caused by variations in processing accuracy of the spiral body member itself or assembly accuracy when connecting the spiral body member. Is likely to occur. In other words, it is extremely rare for the spiral surfaces of adjacent spiral members to be completely continuous at the connecting portion of the spiral member, and usually there are gaps and displacements around the rotation axis of the spiral surface due to the displacement of the spiral surface in the rotation axis direction. A level difference is caused. For this reason, when such a gap or level difference exceeds a predetermined amount, there is a problem in that coins being conveyed are caught between the spiral body and the guide on the way, and coin clogging is likely to occur. In order to prevent coin clogging, it is necessary to adjust the gap or step of the spiral surface to be a predetermined value or less, the work is complicated, and the desired conveyance distance cannot be easily obtained. is there.

Other objects of the present invention which are not specified here will be apparent from the following description and the accompanying drawings.

In order to achieve this object, the present invention is configured as follows.
(1) The coin transport device of the present invention is a coin transport device that receives coins sent one by one at the entrance and transports them to the exit, and includes first and second guide surfaces that guide the peripheral surface of the coin; A coin guide passage extending from the entrance to the exit, and from the entrance to the exit. A plurality of turntables arranged in a predetermined order and rotating around corresponding rotation axes substantially perpendicular to the third and fourth guide surfaces, and the plurality of turntables projecting into the coin guide passage A coin pusher that is provided on each of the above and rotates around the corresponding rotation axis to push the coin in the coin guide passage, and is driven by a driving device, and each of the plurality of turntables A drive connection mechanism for dynamically connecting and rotating one and the other of the pair of adjacent rotating disks in the rotating directions opposite to each other among the plurality of rotating disks; and the predetermined rotating disk among the plurality of rotating disks An auxiliary drive device that rotationally drives the coin transport device.

  In the coin transfer device of the present invention, a coin guide passage extending from the entrance to the exit, a plurality of rotating disks arranged in a predetermined order from the entrance to the exit of the coin guide passage, and protruding into the coin guide passage A coin pusher provided on each of the plurality of turntables, a drive connection mechanism that drives and connects the plurality of turntables, and an auxiliary drive device that rotationally drives a predetermined one of the plurality of turntables And comprising. The guide passage has first and second guide surfaces that guide the peripheral surface of the coin, and third and fourth guide surfaces that guide one of the front and back surfaces of the coin, respectively. The plurality of turntables rotate around corresponding rotation axes that are substantially perpendicular to the third and fourth guide surfaces. Along with the rotation of these rotating disks, the coin pusher circulates around the corresponding rotation axis. The drive coupling mechanism rotates one and the other of the adjacent pair of rotating disks in opposite directions of rotation. For this reason, the coin pusher of one rotary disk and the coin pusher of the other rotary disk orbit around the corresponding rotation axis while maintaining a predetermined rotational phase difference, and the coin pusher of one rotary disk If the rotation phase difference is set so that a rotational position where the coin pusher of the other rotary disk is almost opposed to each other is obtained, the coin that has been pushed by the coin pusher of the one rotary disk is removed from the other rotary disk. The coin can be subsequently pushed by the coin pusher. Therefore, the coins received at the entrance of the coin guide passage are sequentially pushed by the circulating coin pusher and moved toward the exit along the coin guide passage.

  In this manner, the coin whose circumferential surface is guided by the first and second guide surfaces and whose front or back surface is guided by the third and fourth guide surfaces is pushed by the coin pusher that circulates around the rotation axis. Then, when the coin is moved, the range of the diameter or thickness of the coin that can be transported becomes wide. That is, since the coin pusher projecting into the coin guide passage is disposed between the first and second guide surfaces, the coin pusher is larger than the interval between the first and second guide surfaces and the coin pusher, and If the coin has a diameter smaller than the interval between the first and second guide surfaces, the coin can be moved and supported while being supported by either the first or second guide surface and the coin pusher. . Therefore, the diameter range of the coins that can be conveyed is widened. On the other hand, since coins are pushed and conveyed one by one by the coin pusher, adjacent coins do not overlap in the coin guide passage. Therefore, even if the distance between the third and fourth guide surfaces is set wide, coin clogging does not occur, and the range of the thickness that can be conveyed is widened. Therefore, a plurality of types of coins having different diameters or thicknesses can be transported.

  Further, since the coin is pushed and conveyed by the rotation of the coin pusher, no coin remains as in the prior art device that pushes and conveys the upper coin with the lower coin. Therefore, it is not necessary to collect residual coins. Further, all the coins received from the entrance of the coin guide passage can be discharged from the exit of the coin guide passage without remaining.

  In the coin transport device of the present invention, the auxiliary driving device rotationally drives a predetermined rotating plate among the plurality of rotating plates. As described above, the plurality of turntables are drive-coupled by the drive coupling mechanism. Therefore, the driving force of the auxiliary driving device that rotates the predetermined rotating disk is transmitted to the drive coupling mechanism. In other words, the drive device and the auxiliary drive device cooperate to drive the drive coupling mechanism. Therefore, the number of rotating disks can be increased without increasing the driving force of the driving device, and a desired transport distance can be obtained without requiring a high-power driving device. Furthermore, since the load on the drive device does not increase even if the number of rotating disks is increased in order to extend the transport distance, durability is improved. In addition, since it is only necessary to set the number of turntables according to the transport distance and add an auxiliary driving device as appropriate, a desired transport distance can be easily realized.

  In the present invention, the “guide surface” includes a material that substantially functions as a surface. For example, a linear body may be arranged in parallel to function as a surface. Further, “rotation axis” means a straight line that becomes the center of rotation, and “circulates around the rotation axis” means that an object that is away from the rotation axis rotates around the rotation axis.

  (2) In the coin transport device of the present invention, it is preferable that the drive coupling mechanism has a plurality of gears that rotate integrally with the corresponding rotating disk, and the adjacent gears mesh with each other. In this case, one and the other of the pair of adjacent turntables automatically rotate in opposite directions of rotation. Moreover, all of the plurality of turntables rotate in synchronization. Accordingly, while having a simple structure, the coin pusher of one adjacent rotary disk and the coin pusher of the other rotary disk are in opposite directions around the corresponding rotation axis while maintaining a predetermined rotational phase difference. It can be circulated.

  (3) In the coin transport device of the present invention, the coin guide passage corresponds to at least one of a plurality of coin guide passage portions obtained by dividing the coin guide passage in the extending direction, and an inlet and an outlet of the plurality of coin guide passage portions. Each of the plurality of coin guide passage portions, and a plurality of coin transport units in which the corresponding rotating discs are disposed in each of the plurality of coin guide passage portions. It is preferable that a coin transport unit is connected. In this case, the transfer distance in the coin transfer device can be changed by appropriately setting the number of the connected coin transfer units. Further, by preparing in advance a plurality of types of the coin transport units having different numbers of the rotating disks to be arranged and appropriately combining them, an arbitrary transport distance can be obtained stepwise. That is, the transfer distance can be easily changed by appropriately setting the type and number of the coin transfer units to be connected.

  (4) A coin payout device according to the present invention includes a coin delivery device that separates and feeds coins in a stacked state one by one, and a coin transport that receives the coin sent from the coin delivery device at the entrance and transports it to the exit. A coin payout device for paying out coins to a predetermined place, wherein the coin delivery device is tilted upward at a predetermined angle with a holding bowl for holding coins in a stacked state, and A circular support shelf is formed at the center of the upper surface, and has a plurality of coin locking bodies that are equally spaced and radially extend from the support shelf side in the circumferential direction, and are retained in the retaining bowl. The coin is brought into surface contact with the holding surface between the plurality of coin locking bodies and received one by one, and the coin is pushed by the plurality of coin locking bodies while being supported by the support shelf and the holding surface. A disk, coin receiving means extending from the vicinity of the support shelf in the circumferential direction of the rotating disk, receiving the coins pushed by the rotating disk, and feeding the coins one by one in the circumferential direction of the rotating disk; and the rotating disk A driving device for rotationally driving, wherein the coin conveying device guides one of the first and second guide surfaces for guiding the peripheral surface of the coin, and one of the front surface and the back surface of the coin, respectively. A coin guide passage extending from the entrance toward the exit, and arranged in a predetermined order from the entrance toward the exit, and substantially perpendicular to the third and fourth guide surfaces. A plurality of turntables rotating around corresponding rotation axes, and the corresponding rotation axes provided on the plurality of turntables so as to protrude into the coin guide passages. A coin pusher that pushes the coin in the coin guide passage around the circumference and is driven by the drive device of the coin delivery device, and drivingly connects the plurality of rotating disks, and A drive coupling mechanism for rotating one and the other of the pair of adjacent rotary disks in a rotating direction opposite to each other among the plurality of rotary disks, and an auxiliary drive for rotating the predetermined rotary disk among the multiple rotary disks A coin payout device including the device.

  In the coin payout device of the present invention, the coin delivery device has a holding bowl that holds coins in a stacked state, is inclined upward at a predetermined angle, and a circular support shelf is formed at the center of the upper surface thereof, and is equidistant. In addition, the rotary disk having a plurality of coin locking members extending radially from the support shelf side in the circumferential direction, coin receiving means extending from the vicinity of the support shelf in the circumferential direction of the rotary disk, and the rotary disk are driven to rotate. And a driving device. The rotating disk rotated by the driving device receives coins one by one by bringing the coins into surface contact with the holding surfaces between the plurality of coin locking bodies. Since the plurality of coin locking bodies extend radially from the support shelf side in the circumferential direction, a plurality of types of coins having different diameters are received between the plurality of coin locking bodies. Then, the coin receiving means receives the coin pushed by the plurality of coin engaging members while being supported by the support shelf and the holding surface, and sends it out to the outside in the circumferential direction of the rotating disk. Therefore, the coin delivery device can reliably deliver a plurality of types of coins having different diameters even if they are put into the holding bowl.

  Further, the coin transport device has the same configuration as the coin transport device of (1) above. Therefore, as described in (1) above, the range of the diameter or thickness of the coins that can be transported is widened, and a plurality of types of coins having different diameters or thicknesses can be transported. Further, it is not necessary to collect the remaining coins, and all the coins received from the entrance of the coin guide passage can be discharged from the exit of the coin guide passage without remaining. Furthermore, a desired transport distance can be obtained without requiring a high-power drive device, durability can be improved, and the desired transport distance can be easily realized.

  Therefore, in the coin payout device of the present invention, coins stored for a plurality of types of coins having different diameters can be separated one by one and then conveyed to a predetermined position for payout. Further, the range of the diameter or thickness of the coins that can be paid out becomes wider. Further, all the coins inserted into the coin sending device can be released without remaining, and the remaining coins need not be collected. Moreover, a desired payout position can be easily obtained and durability is high. Furthermore, a desired payout position can be obtained without requiring a high-power drive device.

  (5) In the coin payout device of the present invention, it is preferable that the drive coupling mechanism has a plurality of gears that rotate integrally with the corresponding rotating disk, and the adjacent gears mesh with each other. In this case, as described in the above (2), the coin pusher of one adjacent rotary disk and the coin pusher of the other rotary disk can be handled while maintaining a predetermined rotational phase difference, while having a simple structure. It is possible to circulate around the rotating axis in a direction opposite to each other.

  (6) In the coin payout device of the present invention, the coin guide passage corresponds to at least one of a plurality of coin guide passage portions obtained by dividing the coin guide passage in the extending direction, and an inlet and an outlet of the plurality of coin guide passage portions. Each of the plurality of coin guide passage portions, and a plurality of coin transport units in which the corresponding rotating discs are disposed in each of the plurality of coin guide passage portions. It is preferable that the coin transport device is configured by connecting a coin transport unit. In this case, as described in (3) above, the transfer distance can be easily changed by appropriately setting the type and number of the coin transfer units to be connected. That is, the coin payout position can be easily changed.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  1 and 2 show a coin payout device 1 according to an embodiment of the present invention. This coin payout device 1 has a function of paying out coins stacked one by one to a predetermined payout position, and is roughly configured to include a coin sending device 10 and a coin transport device 20. The coin payout device 1 can pay out a plurality of types (that is, denominations) of coins having different diameters or thicknesses, and functions as a so-called size-free coin payout device.

(Coin delivery device)
First, the coin sending device 10 will be described with reference to FIGS. The coin sending device 10 has a function of separating and sending out coins in a stacked state one by one, and a holding bowl 102 for holding a large number of coins, and an attachment for supporting and fixing the holding bowl 102 inclined upward. A base 104, a rotating disk 106 for sorting coins one by one, a driving device 108 for driving the rotating disk 106, a coin receiving means 112 for receiving coins from the rotating disk 106, and a coin dropping means 118 are provided.

(Holding bowl)
The holding bowl 102 has a function of holding a large number of coins in a stacked state and feeding them to the rotating disk 106. The storage bowl 102 projects forward (right side in FIG. 3) from the mounting base 104 and increases in depth as it approaches the rotating disk 106, in other words, the bottom wall 122 is inclined downward toward the rotating disk 106. The head portion 102 </ b> A, a coin insertion slot 102 </ b> B for inserting coins, and an exterior portion 102 </ b> C that is in close contact with the mounting base 104 and surrounds at least the lower outer periphery of the rotating disk 106.

  The inclination of the bottom wall 122 is an angle at which a coin can slide down to the rotating disk 106 side by its own weight. The head portion 102 </ b> A has a so-called saddle shape in which the rotating disk 106 side is opened, and an open end portion thereof is closely fixed to the mounting base 104. As shown in FIG. 5, a narrow vertical groove 124 is formed in front of the lower portion of the rotary disk 106 so that a dropped coin can easily stand. The vertical groove 124 is formed by a vertical wall 126 inclined to the rotating disk 106 side with respect to a perpendicular line substantially parallel to the rotating disk 106 formed subsequent to the exterior part 102C, the rotating disk 106, and the exterior part 102C. In this case, the distance between the upper surface of the rotating disk 106 and the vertical wall 126 of the holding bowl 102 is set to be smaller than the diameter of the minimum coin and 5 to 10 times the thickness of the maximum thickness coin. The interval is set to be wider toward the downstream side in the rotation direction. This is because the coin is stood and further tilted toward the rotating disk 106 so that the coin can be paid out by being locked to a coin locking body 128 described later until the last one.

  The exterior portion 102 </ b> C has a cylindrical ring shape, and is disposed close to the outer periphery of the rotating disk 106. Therefore, coins having different diameters are retained in a stacked state in the retaining bowl 102, slide down on the inclined bottom wall 122 due to their own weight, and are fed into the rotating disk 106. Further, the coins rotated by the rotating disk 106 are guided by the exterior portion 102C so as to remain on the rotating disk 106.

(Mounting base)
The mounting base 104 has a function of rotatably supporting the rotating disk 106 and fixing the storage bowl 102. The mounting base 104 includes two horizontal mounting bases 104A, a first mounting part 104B inclined with respect to the mounting base 104A, a second mounting part 104C extending vertically upward from the upper end of the first mounting part 104B, and a mounting base 104B. It includes support side walls 104L and 104R which are erected substantially at right angles to the mounting portion 104A. The mounting table portion 104A has a rectangular flat plate shape and is formed integrally with the supporting side walls 104L and 104R. The first mounting portion 104B has a flat plate shape and is inclined at an upward angle of about 60 degrees with respect to the mounting table portion 104A. The rotating disk 106 is disposed on the upward upper surface 104U side, and the driving device 108 is disposed on the rear surface side. Is installed. The inclination angle of the first mounting portion 104B is preferably in the range of 50 degrees to 70 degrees. This is because when the angle is smaller than 50 degrees, the amount of coins to be retained decreases, and when the angle is larger than 70 degrees, the coins easily fall from a coin locking body 128 described later. The second attachment portion 104C is formed integrally with the first attachment portion 104B and supports the coin transport device 20.

(Rotating disc)
The rotating disk 106 has a function of sorting coins with different diameters one by one and conveying them to the coin receiving means 112. The rotating disk 106 is a disc, and has a circular central protrusion 132 at the center, a ring-shaped holding surface 134 around the central protrusion 132, and a coin locking body 128 radially formed on the holding surface 134. Is disposed close to the upward upper surface 104U. The rotating disk 106 is inclined upward and rotated counterclockwise in FIG. It is preferable to form a protrusion 133 on the upper surface of the central protrusion 132 and thereby stir the coin.

  The outer periphery of the central protrusion 132 is a support shelf 136, the support shelf 136 is substantially perpendicular to the holding surface 134, and the amount of protrusion from the holding surface 134 is set lower than the thickness of the thinnest coin expected to be used. ing. The support shelf 136 has a function of holding only one coin on the holding surface 134 between the coin locking bodies 128. This is because two coins are not supported by the support shelf 136.

  The holding surface 134 has a function of holding a coin in surface contact with one surface of a coin whose peripheral surface is supported by the support shelf 136. The holding surface 134 is a ring-shaped flat surface formed on the outer periphery of the central protrusion 132 and is inclined about 60 degrees with respect to the horizontal plane.

  The coin locking body 128 is in contact with the circumferential surface of the coin and has a function of pushing the coin. The coin locking body 128 is a rib-like ridge formed in a fixed state radially at equal intervals with respect to the rotation axis of the rotary disk 106. In this embodiment, the coin locking body 128 has a trapezoidal trapezoidal shape when viewed from the front, and pushes the coin by the pushing edge 138 at the front end in the rotational direction. The pushing edge 138 extends vertically upward with respect to the holding surface 134, and the height from the holding surface 134 may be a height that can push the coin. However, when the height of the pushing edge 138 is low, the contact pressure per unit length when pushing the coin increases, so it is preferable that the pushing edge 138 be as high as possible. On the other hand, when the height of the pushing edge 138 is higher than a predetermined amount, the length of the climbing slope 142 for the coin receiving means 112 described later becomes long, and the coin with the smallest diameter is pushed by the pushing edge 138. Sometimes it is pushed up by the climbing slope 142, and the coin with the smallest diameter is easily dropped from the coin receiving means 112. Therefore, it is preferable that the pushing edge 138 is formed as high as possible within a range in which the coin having the smallest diameter is pushed by the pushing edge 138 and is not pushed up by the riding slope 142. According to experiments, when a coin having a diameter of 20 mm or more is targeted, the height of the pushing edge 138 is preferably about 2 mm.

  As shown in FIG. 4, the rotation direction downstream edge 144 of the coin locking body 128 is a pushing edge so that the entire length of the receiving edge 146 of the coin receiving body 145 constituting the coin receiving means 112 is simultaneously close to the holding surface 134. It is preferable to form it inclined with respect to 138. This is because when the coin receiver 145 comes close to the holding surface 134, no coin is sandwiched between the holding surface 134 and the coin receiver 145. The top portion 147 and the downstream edge 144 of the coin locking body 128 are formed on a stepped slope 149. One surface of the coin is held in surface contact with the holding surface 134 between the adjacent coin locking bodies 128. Therefore, the distance between the pushing edge 138 and the downstream edge 144 on the holding surface 134 is such that the support shelf 136 side is narrow and gradually expands toward the periphery of the rotating disk 106, and the holding surface 134 has a central protrusion 132. In contrast, it exhibits an inverted trapezoid. When one of the minimum diameter coins expected to be used is supported on the support shelf 136, the other minimum diameter coin is set not to be supported by the support shelf 136. In other words, the two coins having the smallest diameter are set so as not to come into surface contact with the holding surface 134 at a position close to the support shelf 136. This is to prevent two coins from being continuously paid out.

  The climbing slope 142 has a function of pushing up the end of the receiving edge 146 of the coin receiving body 145 on the support shelf 136 side from the holding surface 134 along this end. As shown in FIG. 4, the climbing slope 142 is formed at a corner formed by the support shelf 136 and the pushing edge 138, and slopes from the holding surface 134 to the top 147 of the coin locking body 128, and has a minimum diameter. When coins are in contact with the support shelf 136 and the pushing edge 138, they are preferably formed in a triangular space formed by them. This is because, when the climbing slope 142 is too large, a part of the coin is placed on the climbing slope 142 in a state where the coin is guided to the receiving edge 146, and the coin easily falls from the receiving edge 146.

(Driver)
The driving device 108 has a function of rotating the rotating disk 106 at a predetermined speed. In this embodiment, the driving device 108 includes an electric motor 152 and a speed reducer 154. A reduction gear 154 is fixed to the back surface of the first mounting portion 104B, and an output gear (not shown) of an electric motor 152 fixed to the reduction gear 154 is engaged with the input gear. An output shaft (not shown) of the speed reducer 154 passes through the first mounting portion 104B, and is tightly inserted and fixed in a fitting hole (not shown) in the center of the rotary disk 106.

  The driving device 108 has an overload prevention function. That is, when the drive device 108 is overloaded due to an abnormality such as a coin jam, a reverse polarity current flows through the electric motor 152 by a control device (not shown) and the rotating disk 106 is rotated in reverse. As a result, when the abnormality is resolved and the load state of the drive device 108 becomes normal, the rotating disk 106 is rotated forward again by the control device.

(Coin receipt means)
The coin receiving means 112 has a function of moving the coins that are divided and sent one by one by the rotating disk 106 in the circumferential direction of the rotating disk 106 and performing an escaping movement with respect to the coin locking body 128. In this embodiment, the coin receiving means 112 is a pentagonal plate body, the receiving edge 146 is formed with a straight receiving edge 146 facing the pushing edge 138, and the other end is movably supported by the floating support means 174. In addition, the coin receiving member 145 is urged toward the rotary disk 106 by a biasing means (not shown) at the intermediate portion.

  When the receiving edge 146 extends in a straight line from the vicinity of the support shelf 136 in the circumferential direction of the rotary disk 106 and is opposed to the pushing edge 138 (when a coin is positioned therebetween), the extension line of the edges is It is formed to make an acute angle. In other words, as shown in FIG. 4, the receiving edge 146 is offset upward with respect to the center of the rotary disk 106 and faces the entire length of the holding surface 134 in the circumferential direction.

  The floating support means 174 has a function of supporting the coin receiving means 112 so that the posture can be changed in any direction, up, down, left, and right within a predetermined range. Specifically, the coin receiving means 112 can move so as to get over the coin locking body 128 while being in contact with the climbing slope 142 and the position where the receiving edge 146 is close to the holding surface 134. The floating support means 174 has the same configuration as that of the above-described Patent Document 2 (Japanese Patent Laid-Open No. 2008-97322), and the description of the specific configuration is omitted here.

(Coin dropping means)
The coin dropping unit 118 has a function of dropping a coin placed on the coin held in contact with the holding surface 134 so that the overlapping coins do not reach the coin receiving unit 112. The coin dropping means 118 is disposed above the axis of the rotating disk 106 and relative to the periphery of the rotating disk 106. In other words, the coin dropping means 118 is at a position of about 2 o'clock with respect to the rotating disk 106, and as shown in FIG. 4, the coin dropping means 118 is moved forward and backward in a plane parallel to the holding surface 134 of the rotating disk 106. It is configured to be possible. The coin dropping means 118 has the same configuration as that of Patent Document 2 (Japanese Patent Laid-Open No. 2008-97322) described above, and detailed description thereof is omitted here.

  The heights of the coin pushers 550A and 550B of the turntable 501 and the turntable 502 (in other words, the protruding length from the surface of the turntable) are the heights of the coin pushers 550A and 550B of the turntable 503 to the turntable 548. On the other hand, it is set to be large. This is because, in order to convey a coin while changing the advancing angle of the coin, it is necessary to reliably push the coin even when the coin is inclined. The heights of the coin pushers 550A and 550B of the turntable 503 to the turntable 548 are the same.

  The coin pushers 550A and 550B may be formed integrally with the turntables 501 to 548, or may be formed separately by being fixed to the turntables 501 to 548 by an appropriate method. In this embodiment, they are integrally formed from the viewpoint of reducing manufacturing costs. Further, the coin pushers 550A and 550B may be columnar bodies, or may be a rotatable roller type in which a support shaft is covered with a cylindrical collar. In the case of the roller type, there is an advantage that wear of the coin pushers 550A and 550B is suppressed and durability can be enhanced.

  As described above, the rotation axes 702 to 748 are alternately arranged in a zigzag manner on the first and second axis arrangement lines 312 and 314.

A shaft insertion hole 560 shown in FIG. 11 is formed in each of the turntables 502 to 548 and the gears 902 to 948. Corresponding support shafts 802 to 848 are inserted into the shaft insertion holes 560, respectively. The gears 902 to 948 may be formed integrally with the turntables 502 to 548, or may be formed separately by being fixed to the turntables 502 to 548 by an appropriate method. It is only necessary that the rotating plates 502 to 548 and the gears 902 to 948 can rotate integrally. In this embodiment, they are integrally formed from the viewpoint of reducing manufacturing cost and improving coaxial accuracy.

  The gears 902 to 948 mesh with each other adjacent to each other. For example, the gear 903 meshes with the gears 902 and 904, and the gear 905 meshes with the gears 904 and 906. Similarly, the gear 945 meshes with the gears 944 and 946, and the gear 947 meshes with the gears 946 and 948. Therefore, as shown in FIG. 10, the rotating disks 502, 504, 506, 508, 510, 512, 514, 516, 518, 520, 522, 524, 526, 528, 530, 532 belonging to the first rotating disk group. 534, 536, 538, 540, 542, 546, 548 rotate counterclockwise, and turntables 503, 505, 507, 509, 511, 513, 515, 517, 519 belonging to the second turntable group, 521, 523, 525, 527, 529, 531, 533, 535, 537, 539, 541, 543, 545, 547 rotate in the clockwise direction. That is, the rotating disks 502, 504, 506, 508, 510, 512, 514, 516, 518, 520, 522, 524, 526, 528, 530, 532, 534, 536, 538, belonging to the first rotating disk group, 540, 542, 546, and 548, and rotating plates 503, 505, 507, 509, 511, 513, 515, 517, 519, 521, 523, 525, 527, 529, 531, 533 belonging to the second rotating plate group. 535, 537, 539, 541, 543, 545, and 547 rotate in directions opposite to each other. Therefore, the coin pushers 550A and 550B belonging to the first pusher group and the coin pushers 550A and 550B belonging to the second pusher group circulate in opposite directions.

  In a pair of adjacent ones of the rotary disks 502 to 548, the coin pushers 550A and 550B are arranged so as to maintain a predetermined rotational phase difference. For example, the coin pushers 550A of the adjacent turntable 502 and turntable 503 are arranged so as to maintain a predetermined rotational phase difference. Similarly, coin pushers 550B of adjacent turntable 502 and turntable 503 are arranged so as to maintain a predetermined rotational phase difference. Specifically, as shown in FIG. 10, when a plane P including the rotation axes 702 and 703 is defined, when the coin pusher 550A of the turntable 502 reaches the plane P, the coin pusher 550A of the turntable 503 is reached. , The coin pusher 550A of the turntable 502 and the coin pusher 550A of the turntable 503 are arranged so that they reach a position before ½ of the gear pitch with respect to the plane P. Similarly, when the coin pusher 550B of the turntable 502 reaches the plane P, the coin pusher 504B of the turntable 503 reaches a position in front of the plane P by 1/2 of the gear pitch. A coin pusher 550A of the turntable 502 and a coin pusher 550A of the turntable 503 are arranged. The same applies to each of the turntable 503 and the turntable 504, the turntable 504 and the turntable 505,..., The turntable 546 and the turntable 547, and the turntable 547 and the turntable 548.

  As described above, the coin pushers 550A and 550B of the rotary disks 502 to 548 circulate around the corresponding ones of the rotation axes 702 to 748 synchronously while maintaining a predetermined rotational phase difference. In addition, among the coin pushers 550A and 550B of the turntables 502 to 548, those adjacent to each other in the rotation axis circulate in directions opposite to each other.

  A gear 612 having a spur gear portion 622 and a bevel gear portion 626 is coaxially provided on the back surface of the rotating disk 501. A gear 614 having a spur gear portion 624 and a bevel gear portion 628 is coaxially provided on the back surface of the gear 902 of the rotating disk 502. These two gears 612 and 614 have the same shape, and the bevel gear portions 626 and 628 each have a cone angle of about 30 degrees. In other words, the bevel gear portions 626 and 628 each have a cone angle corresponding to the angle α formed by the rotation axis 701 and the rotation axis 702.

  The bevel gear portion 626 of the gear 612 and the bevel gear portion 628 of the gear 614 mesh with each other. Therefore, the turntable 501 and the turntable 502 rotate in directions opposite to each other. That is, as shown in FIG. 10, the turntable 501 rotates clockwise and the turntable 502 rotates counterclockwise. Accordingly, the coin pushers 550A and 550B of the rotary disk 501 and the coin pushers 550A and 550B of the rotary disk 502 circulate in directions opposite to each other. Also in the rotary plates 501 and 502, the coin pusher 550A of the rotary disc 501 and the coin pusher 550A of the rotary disc 502 are arranged so as to maintain a predetermined rotational phase difference, and the coin pusher 550B of the rotary disc 501 and the rotary disc. The coin pusher 550B 502 is arranged so as to maintain a predetermined rotational phase difference. As a result, the coin pushers 550A and 550B of the turntable 501 and the coin pushers 550A and 550B of the turntable 502 are synchronized while maintaining a predetermined rotational phase difference around the corresponding rotation axes 701 and 702 in opposite directions. And go around.

  As described above, the bevel gear portions 626 and 628 have a cone angle corresponding to the angle α formed by the rotation axis 701 and the rotation axis 702. Therefore, the rotating disks 501 and 502 can be rotationally driven in a state where the angle α formed by the rotation axes 701 and 702 is formed, with a simple configuration in which the gears 612 and 614 are engaged with each other.

  The spur gear portion 622 and the bevel gear portion 626 may be formed integrally, or may be formed separately and fixed to each other by an appropriate method. In this embodiment, they are integrally formed from the viewpoint of reducing manufacturing cost and improving coaxial accuracy. The same applies to the spur gear portion 624 and the bevel gear portion 628. The gear 612 can be formed integrally with the rotating disk 501, and the gear 614 can be formed integrally with the gear 902. When formed integrally, it is advantageous to reduce the manufacturing cost and increase the coaxial accuracy. In this embodiment, it is formed integrally. However, it is formed integrally by fixing them separately by an appropriate method. Of course, it is also possible. Any configuration may be used as long as the turntables 501 and 502 and the gears 612 and 614 can rotate integrally.

  As described above, the gears 612 and 614 and the gears 902 to 948 drive and connect the rotary plates 501 to 548 and rotate one and the other of the pair of adjacent rotary plates of the rotary plates 501 to 548 in mutually opposite rotational directions. A drive coupling mechanism 950 is configured.

(Driving force transmission mechanism)
As shown in FIGS. 17 to 19, the driving force transmission mechanism 600 is provided coaxially with the gear 602 disposed on the back side of the rotating disk 106 of the coin delivery device 10, the gear 604 that meshes with the gear 602, and the gear 604. In addition, a gear 610 to which a torque limiter 611 is attached, a gear 606 that meshes with the gear 610, and a gear 608 that is coaxial with the gear 606 are included. The gear 602 is fixed to the rotating disk 106, and the gear 608 meshes with the spur gear portion 622 of the gear 612.

  When the rotating disk 106 is rotated by the driving device 108 of the coin delivery device 10, the gear 602 rotates integrally with the rotating disk 106, and the rotational driving force is transmitted to the gear 612 via the gears 604, 610, 606 and 608. Is done. The gear 612 to which the rotational driving force is transmitted rotates, and the rotational driving force is transmitted to the gears 902 to 948 via the gear 614. In other words, the drive coupling mechanism 950 is driven by the drive device 108, and all of the rotating disks 501 to 548 rotate.

  The driving force transmission mechanism 600 is configured such that the rotating disk 106 of the coin delivery device 10 and the rotating disk 501 of the coin transport device 20 have a predetermined rotational speed difference. That is, the rotational speeds of the rotating disk 106 and the rotating disk 501 are set so that the rotating disk 501 rotates 180 degrees every time the rotating disk 106 rotates 45 degrees. By setting the rotation speed in this way, when each of the eight pushing edges 138 of the rotating disk 106 cooperates with the coin receiving means 112 to send out a coin, the coin pushing body 550A of the turntable 501; 550B moves to the optimum position for pushing each of the sent coins. In other words, all the coins sent out by each of the eight pushing edges 138 of the rotating disk 106 can be reliably pushed by any one of the coin pushing bodies 550A and 550B of the rotating disk 501. Become.

  A rotation shaft 604a of a gear 604 is connected and fixed to a central shaft 611a that is an input shaft of the torque limiter 611, and a fitting hole (not shown) of the gear 610 is formed on an outer peripheral surface 611b that is an output shaft of the torque limiter 611. Is inserted and fixed. As a result, when an excessive torque greater than or equal to a predetermined value is applied to the gear 604, the torque is interrupted and the gear 604 idles. In other words, when excessive rotation resistance of a predetermined value or more is applied to the rotating plates 501 to 548 due to the occurrence of coin biting in the coin transport device 20, the input shaft and the output shaft of the torque limiter 611. The rotational force is released between the two and the rotating disks 501 to 548 are prevented from forcibly rotating. Thereby, since an excessive load is not applied to related parts, there is an advantage that durability is improved.

  As shown in FIG. 19, a rotation monitoring sensor 650 for monitoring the rotation state of the rotating disks 501 to 548 is provided on the rotation shaft 606 a of the gear 606. The rotation monitoring sensor 650 includes an encoder disk 652 fixed to the lower end of the rotation shaft 606a and a transmission type photoelectric sensor 654. The encoder disc 652 is formed with a plurality of through holes (not shown) arranged at equal intervals along the periphery. The photoelectric sensor 654 includes a light projector (not shown) that emits light toward the through hole of the encoder disk 652 and a light receiver (not shown) that receives the light from the light projector and generates an electrical signal. Is done. When the turntables 501 to 548 rotate, the rotation monitoring sensor 650 outputs a pulse signal synchronized with the rotation angle. By monitoring the state of this pulse signal, the operating state of the torque limiter 611 can be detected. That is, when the torque limiter 611 is inactive, a pulse signal having a predetermined cycle is output from the rotation monitoring sensor 650, and when the torque limiter 611 is in an operating state, a pulse signal having a cycle longer than the predetermined cycle is output from the rotation monitoring sensor. Since the output is 650, the non-operation / operation state of the torque limiter 611 can be detected by measuring the period of the pulse signal. When the torque limiter 611 is activated, the electric motor 152 is stopped and the rotation of the rotary disk 106 is stopped. As a result, the coin feeding from the coin sending device 10 is stopped and the coin is prevented from continuing to be supplied to the coin transport device 20 where the coin is biting, so that an unnecessary load is applied to the related parts. Can be prevented, and durability is improved.

  As the torque limiter 611, for example, a known one such as a torque limiter having a steel ball and a concave groove disclosed in Japanese Patent Application Laid-Open No. 2001-263364 can be used, and in particular, a pair facing each other across the rotation axis. Those having a concave groove are preferred. In that case, the non-operating state of the torque limiter 611 (that is, the state in which the steel ball is locked in the concave groove) is generated at a rotation angle of 180 degrees. The rotational phase difference with the 20 turntables 501 is maintained.

The flip roller 232 is exposed to the outlet passage region 220 of the third coin guide passage portion 210C through an arc-like flip roller slot 236 formed in the third top plate portion 400C. The coin releasing means 230 is attached to the third coin transport unit 23 by fixing the frame 231 to the third base portion 300C with screws (not shown) penetrating the third top plate portion 400C.

  The coin payout detection sensor 240 is disposed so as to straddle the exit passage area 220 of the third coin guide passage portion 210 </ b> C immediately before the exit 204. The coin payout detection sensor 240 is a photoelectric sensor that has a channel-shaped resin-made outer case 242 and has a projector built in one of the two columnar portions 244 and a light receiver built in the other, and is opposed to each other. . When the coin passes between the two columnar portions 244 in the exit passage region 220, the optical path is blocked, and the coins are detected one by one by the detection signal output based on the light path.

When the gear 904 and the gear 905 are engaged with each other, the gear 904 is set so that the above-described predetermined phase difference is generated between the coin pushers 550A and 550B of the rotary disc 504 and the coin pushers 550A and 550B of the rotary disc 505. , 905 to adjust the position of the teeth. When the coin transport unit 22 is pressed against the coin transport unit 21 in this state, the gear 904 and the gear 905 are engaged with each other, and the end surface 322B of the connection portion 261B comes into contact with the end surface 322A of the connection portion 251 to stop the insertion. . In other words, the end surface 322A and the end surface 322B function as a butting surface for positioning. Further, screws (not shown) inserted into the screw insertion holes 256 of the connection portion 251 and the screw insertion holes 269 of the connection portion 261B are screwed into the screw holes 257 of the connection portion 251. Similarly, screws (not shown) inserted into the screw insertion holes 266 of the connection portion 261B and the screw insertion holes 259 of the connection portion 251 are screwed into the screw holes 267 of the connection portion 261. Thereby, the coin transport unit 22 is fixed to the coin transport unit 21.

  When the intermediate coin transport unit 22 and the coin transport unit 23 are connected, a gear 910 exposed from the opening 263 of the connection portion 261A of the coin transport unit 22 and a gear 911 exposed from the opening 263 of the connection portion 261B of the coin transport unit 23. Are inserted into the groove 265 of the connection portion 261B of the coin transport unit 23, and the protrusion 258 of the connection portion 261B of the coin transport unit 23 is inserted into the coin. It is inserted into the groove portion 265 of the connection portion 261A of the transport unit 22. When the gear 910 and the gear 911 are meshed with each other, the gear 910 is set so that the above-described predetermined phase difference is generated between the coin pushers 550A and 550B of the turntable 510 and the coin pushers 550A and 550B of the turntable 511. , 911 tooth position is adjusted. When the coin transport unit 23 is pressed against the coin transport unit 22 in this state, the gear 910 and the gear 911 are engaged with each other, and the end surface 322B of the connection portion 261B of the coin transport unit 23 is the end surface of the connection portion 261A of the coin transport unit 22. The insertion is stopped in contact with 322B. In other words, the end surface 322B of the coin transport unit 22 and the end surface 322B of the coin transport unit 23 function as a butting surface for positioning. Further, screws (not shown) inserted into the screw insertion holes 266 and the screw insertion holes 269 of the connection portions 261A and 261B of the coin transport units 22 and 23 are screwed into the screw holes 267 of the connection portions 261A and 261B. Thereby, the coin transport unit 23 is fixed to the coin transport unit 22. The intermediate coin transport units 23 to 28 are also connected in the same manner as described above.

  When the intermediate coin transport unit 28 and the uppermost coin transport unit 29 are connected, the gear 946 exposed from the opening 263 of the connection portion 261A and the gear 947 exposed from the opening 273 of the connection portion 271 are engaged with each other. The protrusion 278 of the portion 271 is inserted into the groove portion 265 of the connection portion 261A, and the protrusion 268 of the connection portion 261A is inserted into the groove portion 275 of the connection portion 271. When the gear 946 and the gear 947 are engaged with each other, the gear 946 is set so that the above-described predetermined phase difference is generated between the coin pushers 550A and 550B of the rotary disc 546 and the coin pushers 550A and 550B of the rotary disc 547. , 947 teeth position is adjusted. When the coin transport unit 29 is pressed against the coin transport unit 28 in this state, the gear 946 and the gear 947 are engaged with each other, and the end surface 322C of the connection portion 271 contacts the end surface 322B of the connection portion 261A to stop the insertion. . In other words, the end surface 322B and the end surface 322C function as a butting surface for positioning. Further, screws (not shown) inserted into the screw insertion holes 266 of the connection portion 261A and the screw insertion holes 279 of the connection portion 271 are screwed into the screw holes 267 of the connection portion 261A. Similarly, a screw (not shown) inserted into the screw insertion hole 276 of the connection portion 271 and the screw insertion hole 269 of the connection portion 261A is screwed into the screw hole 277 of the connection portion 271. Thereby, the coin transport unit 29 is fixed to the coin transport unit 28.

  In this way, the uppermost coin transport unit 21 and the lowest coin transport unit 29 are connected via the intermediate coin transport units 22 to 28, and the states of FIGS. 1 to 3 and FIGS. 7 to 10 are realized. That is, the base body 300 is configured by the first to third base portions 300A to 300C, and the top plate 400 is configured by the first to third top plate portions 400A to 400C. First to third coin guide passage portions 210A to 210C are communicated to form a coin guide passage 210. 7, in the base body 300, the first members 306A to 306C of the first to third base portions 300A to 300C constitute the first member 306, and the first to third base portions 300A to 300C. The second members 308 </ b> A to 308 </ b> C constitute the second member 308.

  That is, the base body 300 includes a structure in which the second member 308 is stacked on the first member 306, and the through hole 315 is formed in the second member 308. The through-hole 315 has a planar shape in which 47 circular holes having the same inner dimensions are connected in a zigzag shape with a part thereof being overlapped, and as shown in FIG. It has the 1st opening 315a with a small internal dimension arrange | positioned at the surface side, and the 2nd opening 315b with a large internal dimension arrange | positioned at the back surface side. The back surface side of the through hole 315 is closed by the second member 308, and a recess 316 is formed in the base body 300.

  The turntables 502 to 548 are accommodated in the first opening 315a. In the second opening 315b, gears 902 to 948L corresponding to the rotary plates 502 to 548 are accommodated. Support shafts 803 to 848 are provided on the bottom surface 318 of the recess 316. As shown in FIGS. 8 and 11, the support shafts 803 to 836 and 838 to 848 are attached to the base body by a fixing screw 310 inserted into the screw hole 340 via the second member 308 from the back surface 304 side of the base body 300. It is fixed to 300.

  The respective surfaces of the turntables 501 to 548 are arranged so as to be substantially flush with the surface 302 of the base body 300. Therefore, the coin pushers 550 </ b> A and 550 </ b> B provided on the respective surfaces of the rotating disks 501 to 548 protrude above the surface 302 of the base body 300. In other words, the coin pushers 550A and 550B protrude into the coin guide passage 210, respectively.

  The coin pushers 550A and 550B protruding into the coin guide passage 210 circulate around the corresponding rotation axes 701 to 748 as the turntables 501 to 548 rotate, and the coins in the coin guide passage 210 are put one by one. Push. The pushed coin is guided in the coin guide passage 210 while the circumferential surface is guided by the first and second guide surfaces 212 and 214 and the front or back surface is guided by the third and fourth guide surfaces 216 and 218. Moved. In this case, the range of the diameter or thickness of the coins that can be conveyed is widened. That is, since the coin pushers 550A and 550B protruding into the coin guide passage 210 are disposed between the first and second guide surfaces 212 and 214, the first and second guide surfaces 212 and 214 and the coin pusher 550A. (In other words, larger than the interval generated between the first and second guide surfaces 212, 214 and the orbit of the coin pushers 550A, 550B), and the first If the coin has a diameter smaller than the distance between the first and second guide surfaces 212 and 214, either one of the first and second guide surfaces 212 and 214 and the coin pusher 550A or the coin pusher 550B It can be transported while being supported. Therefore, the diameter range of the coins that can be conveyed is widened. On the other hand, since coins are pushed and conveyed one by one by the coin pushers 550A and 550B of the rotary plates 501 to 548, adjacent coins do not overlap in the coin guide passage 210. Therefore, even if the distance between the third and fourth guide surfaces 216 and 218 is set wide, coin clogging does not occur. Therefore, the thickness range of the coins that can be conveyed is widened.

  The coin transport device 20 is configured by connecting intermediate coin transport units 22 to 28 between the lowest coin transport unit 21 and the uppermost coin transport unit 29. Therefore, the conveyance distance in the coin conveyance device 20 can be easily changed by appropriately setting the number of intermediate coin conveyance units 22 to 28.

(Auxiliary drive device)
As shown in FIGS. 3 and 20, the auxiliary drive device 30 is attached to the intermediate coin transport unit 27. In the present embodiment, the auxiliary drive device 30 includes an electric motor 661 and a speed reducer 662. The speed reducer 662 is fixed to the back surface of the second member 308B constituting the second base portion 300B of the coin transport unit 27, and the output of the electric motor 661 fixed to the speed reducer 662 is input to an input gear (not shown). A gear (not shown) is engaged. The output shaft 663 of the speed reducer 662 passes through the second member 308 </ b> B and is closely fitted in the fitting hole 837 a of the support shaft 837. In addition, the support shaft 837 is closely fitted into the rotary disk 537 and the shaft insertion hole 560 of the gear 937. Therefore, the output shaft 663, the support shaft 837, the rotating disk 537, and the gear 937 of the speed reducer 662 can rotate together. In other words, the rotating disk 537 and the gear 937 are rotated by the driving force of the electric motor 661. The reduction ratio of the speed reducer 662 is set so that the rotational speeds of the rotary disks 501 to 536 and 538 to 548 and the rotational speed of the rotary disk 537 are substantially the same.

  As described above, the rotating disks 501 to 548 are rotated in a predetermined direction by the drive coupling mechanism 950, and the rotating disk 537 is rotated in the clockwise direction in FIG. The auxiliary drive device 30 rotates the rotating disk 537 and the gear 937 in the same clockwise direction as the rotation direction of the drive coupling mechanism 950. The driving force by the auxiliary driving device 30 is transmitted via the drive coupling mechanism 950. Therefore, the drive device 108 and the auxiliary drive device 30 cooperate to drive the drive coupling mechanism 950 to rotate the rotating disks 501 to 548. In other words, it is possible to drive the lower rotating disk among the rotating disks 501 to 548 by the driving device 108 and rotate the upper rotating disk by the auxiliary driving device 30. As a result, the number of rotating disks can be increased without increasing the driving force of the driving device 108. In other words, the load on the driving device 108 does not increase even if the number of rotating disks is increased in order to extend the transport distance.

  Table 1 shows experimental results showing changes in the current value of the electric motor 152 of the driving device 108 due to the attachment of the auxiliary driving device 30.

  Comparing (1) to (3) in Table 1 above, it can be seen that the load on the driving device 108 is reduced by attaching the auxiliary driving device 30 to the coin transport units 26 and 28. In the case of (4) in which the auxiliary driving device 30 is attached to the coin transport unit 22, the driving efficiency of the driving device 108 and the auxiliary driving device 30 is lowered. The results of Table 1 above show that the driving efficiency is changed by the intermediate coin transport units 22 to 28 to which the auxiliary drive device 30 is attached, and the drive device 108 and the auxiliary drive device 30 are attached to any one of the coin transport units 26 to 28. It shows that the driving efficiency of the auxiliary driving device 30 is improved.

  When the turntables 501 to 548 are rotated at a predetermined number of rotations, the ratings of the outputs of the drive device 108 and the auxiliary drive device 30 (in other words, the current flowing through the electric motor 152 and the electric motor 661) can be used continuously. It is preferable to set a turntable that is rotated by the auxiliary drive device 30 so as not to exceed the value. This is because the durability of the driving device 108 and the auxiliary driving device 30 is improved. More preferably, when the turntables 501 to 548 rotate at a predetermined number of rotations, the sum of the outputs of the drive device 108 and the auxiliary drive device 30 (in other words, the current flowing through the electric motor 152 and the electric motor 661) is minimized. Thus, a turntable that is rotationally driven by the auxiliary drive device 30 is set. This is because the power consumption of the driving device 108 and the auxiliary driving device 30 can be suppressed.

  Generally, when a plurality of gears are sequentially meshed to drive and connect, a transmission loss occurs between adjacent gears, and the transmission loss increases according to the number of gears used. When the high-power electric motor 154 is used for the driving device 108 to compensate for the transmission loss, it is necessary to increase the strength of the gears 602, 604, 606, 608, 610 of the driving force transmission mechanism 600. Larger and heavier. The auxiliary drive device 30 has a function of effectively compensating for the transmission loss, and can prevent the coin delivery device 10 from becoming large and increasing in weight.

(Operation of coin dispensing device)
Next, the operation of the coin payout device 1 will be described with reference to FIGS. In actual operation, a large number of coins are held to the extent that they are piled up in the holding bowl 102. Here, in order to simplify the explanation, it is assumed that four coins C1 to C4 are held in the holding bowl 102.

  FIG. 21 shows a state in which the coins C1 to C4 are conveyed by the rotating disk 106 of the coin delivery device 10, and the coin C1 is placed on the four holding surfaces 134 of the eight holding surfaces 134 of the rotating disk 106. To C4 (C4 is not shown) are held. Each of the coins C <b> 1 to C <b> 4 is moved by being pushed by the coin locking body 128 of the rotating disk 106 that rotates counterclockwise, and the coin C <b> 1 approaches the receiving edge 146 of the coin receiving means 112.

  When the rotating disk 106 further rotates, as shown in FIG. 22, the coin C <b> 1 is pushed by the coin locking body 128 in contact with the receiving edge 146 of the coin receiving means 112 and moved in the circumferential direction of the rotating disk 106. The Then, in a state where the coin C1 is pushed out of the rotary disk 106, the coin C1 is stopped at a delivery position supported by the tip of the coin locking body 128 and the peripheral wall 184. When the coin pusher 550A of the rotating disk 501 rotating in the clockwise direction comes into contact with the circumferential surface of the coin C1 at the delivery position, the coin C1 is pushed by the coin pusher 550A.

  As the turntable 501 rotates, the coin C1 is pushed by the coin pusher 550A of the turntable 501, and the peripheral surface of the coin C1 is pressed against the peripheral wall 184 as shown in FIG. The coin C1 is guided by the peripheral wall 184 and the first guide surface 212 of the coin guide passage 210 and moved upward, and is introduced into the coin guide passage 210 through the inlet 202. Further, the next coin C <b> 2 pushed by the coin locking body 128 of the rotating disk 106 contacts the receiving edge 146 of the coin receiving means 112.

  As the turntable 501 further rotates, the coin C1 is continuously pushed by the coin pusher 550A, and the circumferential surface of the coin C1 is pressed against the second guide surface 214 of the coin guide passage 210 as shown in FIG. Moved upwards. At this time, the coin pusher 550A of the turntable 502 approaches the coin C1 due to the counterclockwise rotation of the turntable 502. As in the case of the coin C1, the coin C2 pushed out of the rotary disk 106 by the coin locking body 128 and the receiving edge 146 of the coin receiving means 112 is pushed by the coin pusher 550B of the turntable 501. Thus, the peripheral surface is guided by the peripheral wall 184 and moved upward. The next coin C3 pushed by the coin locking body 128 of the rotating disk 106 approaches the receiving edge 146 of the coin receiving means 112.

  Further, as shown in FIG. 25, the coin pusher 550A of the rotary disk 502 comes into contact with the coin C1 to push the coin C1, and the coin C1 moves upward while being guided by the second guide surface 214 of the coin guide passage 210. Moved. The coin C2 pushed by the coin pusher 550B of the turntable 501 is introduced into the coin guide passage 210 through the inlet 202. The coin C3 is pushed by the coin locking body 128 in contact with the receiving edge 146 of the coin receiving means 112 and moved in the circumferential direction of the rotary disk 106.

  In the movement of the coin C1 from FIG. 23 to FIG. 25, the coin C1 is moved from the first guide surface portion 222 of the fourth guide surface 218 to the second guide surface portion 224, and the advancing angle of the coin C1 is relative to the horizontal plane. It changes from about 60 degrees to about 90 degrees. At this time, the coin C1 is guided by the first curved surface portion 226 formed between the first and second guide surface portions 222 and 224 and the second curved surface portion 228 disposed so as to face the coin C1. Gradually changes, so that the coin C1 is smoothly moved in the coin guide passage 210.

  Next, as shown in FIG. 26, the coin C <b> 1 pushed by the coin pusher 550 </ b> A of the turntable 502 is moved upward while being guided by the first guide surface 212 of the coin guide passage 210. The coin pusher 550A of the turntable 503 that rotates clockwise approaches the coin C1. The coin C2 pushed by the coin pusher 550B of the turntable 501 is guided upward by the first and second curved surface portions 226 and 228 while gradually changing the advancing angle as in the case of the coin C1. Moved to. The coin C3 pushed out of the rotary disk 106 is pushed by the coin pusher 550A of the turntable 501. The next coin C4 pushed by the coin locking body 128 of the rotating disk 106 approaches the receiving edge 146 of the coin receiving means 112.

  Next, as shown in FIG. 27, the coin C1 is moved upward by the pushing of the coin pusher 550A of the turntable 503, and the coin C2 is moved upward by the push of the coin pusher 550B of the turntable 502, The coin C3 is moved upward by the pushing of the coin pusher 550A of the rotary disk 501. The coin C4 is pushed by the coin locking body 128 in contact with the receiving edge 146 of the coin receiving means 112 and moved in the circumferential direction of the rotary disk 106.

  Further, as shown in FIG. 28, the coin C1 is moved upward by the pushing of the coin pusher 550A of the rotating disk 505, and the coin C2 is moved upward by the pushing of the coin pushing body 550B of the rotating disk 503. The coin C3 is moved upward by the pushing of the coin pusher 550A of the rotating board 502, and the coin C4 is moved upward by the pushing of the coin pushing body 550B of the rotating board 501.

  The state shown in FIG. 29 is caused by repeating the operation of the coin pushing mechanism 500 described above. When the turntable 548 further rotates counterclockwise from this state, the coin C1 pushed by the coin pusher 550A of the turntable 548 is guided to the second guide surface 214 of the coin guide passage 210 as shown in FIG. As a result, the position of the coin discharge means 230 is reached. When the coin C1 is further pushed by the coin pusher 550A of the turntable 548, the coin C1 contacting the flip roller 232 pushes up the turning lever 233 of the coin ejection means 230 against the urging force of the string spring 234. , Move towards exit 204. When the maximum diameter portion of the coin C1 passes the flip roller 232, the rotation lever 233 returns downward due to the elasticity of the string spring 234, and the coin C1 is flipped toward the outlet 204 by the rotational force at that time. It is. As shown in FIG. 31, the coin C <b> 1 is detected by the coin payout detection sensor 240 immediately after being flipped and then discharged from the outlet 204. Thereafter, the same operation is repeated for the coins C2 to C4, whereby the coins C2 to C4 are discharged from the outlet 204.

(Modification)
In addition, this invention is not limited to said Example, A various change is possible. For example, the conveyance distance can be adjusted by changing the number of intermediate coin conveyance units 22 to 28. In particular, when the number of coin transport units 22 to 28 is increased to extend the transport distance, a plurality of auxiliary drive devices 30 are attached, and the attachment positions of the drive devices 108 and the auxiliary drive devices 30 are set appropriately. The driving efficiency can be optimized.

  Also, the lowest coin transfer unit 21 is provided with turntables 501 to 504, and the intermediate coin transfer units 22 to 28 are turntables 505 to 511, 512 to 518, 519 to 525, 526 to 532, and 533. 539 and 540 to 546 are arranged, and the uppermost coin transfer unit 29 is provided with the rotary plates 547 and 548. However, the number of the rotary plates arranged in the coin transfer units 21 to 29 is appropriately changed. Is possible. Thereby, since the length of a coin conveyance unit can be changed, the coin conveyance apparatus 20 of arbitrary length is obtained in steps by the combination of the coin conveyance unit from which length differs.

  Further, the rotary plates 501 to 548 are provided with a pair of coin pushers 550A and 550B, respectively. However, the present invention is not limited to this, for example, one for each of the rotary plates 501 to 548. It is also possible to provide a coin pusher.
