1. Field of the Invention
The present invention relates to a coin-separating and feeding device for sorting a plurality of denominations of coins different in diameter individually to feed them to a subsequent process step.
Incidentally, the term “coin” used in this specification includes a coin which is currency, a token, a medal and the like, and the shape thereof also includes a circular shape and polygonal shape.
2. Description of Related Art
As a first prior art, in a coin processing device which is configured such that, after coins are individually sorted by holding them in sorting recesses arranged on an upper face of a rotating disk, they are delivered to a coin transporting device. A coin feeding device of the coin processing device is configured such that the sorting recesses of the rotating disk are formed in a fan shape opened on an upper face side of the rotating disk and opened on a peripheral face side of the rotating disk, each sorting recess has a coin pushing part at its portion. A mover member forming a portion of the sorting recess and movable in a diametrical direction of the rotating disk is provided in the sorting recess, and the mover member is positioned lateral to the coin pushing part at a coin receiving time, while the mover member is moved to the opened side of the peripheral face when a coin is delivered to the coin transporting device as known (for example, in U.S. Pat. No. 7,255,639).
As a second prior art, a device configured such that a selecting plate having a peripheral edge formed with a semi-circular notch is disposed on an upper side of a partition wall arranged in an inclination fashion, a dispending body reciprocating elastically and linearly from the bottom portion of the notch toward an opening at a peripheral edge of the selecting plate is disposed. A coin is sorted into its corresponding denomination by flipping the coin held at the notch at a predetermined position corresponding to a diameter of the coin in a peripheral direction by linear movement of the dispenser as known (for example, U.S. Pat. No. 1,813,296.
In the first prior art, the mover member unit is rotated about a pivoting shaft and a coin is thrown by partial pivoting of the mover member unit about the pivoting shaft to be delivered to a guide of the coin transporting device.
Therefore, after the coin is thrown, it collides against the guide. In other words, since the coin is thrown toward the guide, it may be jumped up by its reaction to a collision against the guide. The lighter a coin having a small diameter, the larger the amount of the lumping height becomes.
When a coin jumps up against the guide, a problem of erroneous detection occurs because a position of the coin relative to a sensor for detecting physical information regarding the diameter or the quality of the coin, the sensor being arranged based upon the guide, is different from a standard state. For example, there is such a problem that when a coin jumps against the guide, a diameter sensor makes erroneous discrimination such that the coin is a large diameter coin having a diameter larger than a true diameter of the coin, and when a coin to be detected is a bimetal coin, a quality sensor makes erroneous discrimination because a portion of the coin which should basically correspond to a central core portion thereof corresponds to a rim portion of the coin which is positioned at a peripheral portion of the coin.
In the second prior art, also, since a coin is basically flipped out by an elastic linear motion caused by an elastic body of the dispenser, the coin which has been flipped out collides against the guide positioned in the circumferential direction to rebound, so that there is a problem of erroneous discrimination similar to the first prior art.
Further, by combining the first prior art and the second prior art with each other, a coin can be flipped out by moving the mover member unit in the first prior art by the elastic linear motion caused by the elastic body in the second prior art, but even in this case, since the coin is flipped out of the sorting recess, it collides against the guide at the next step to rebound, such a problem as erroneous discrimination occurs like the first prior art.
In order to solve these problems, it may be though that a guide can be extended so that the diameter sensor or the quality sensor is disposed in a region where, even if a coin collides against the guide to rebound, the rebounding of the coin stops and the coin then moves while contacting with the guide. In this case, however, since the guide becomes longer, a problem occurs in that the device itself becomes large in size.
A first object of the present invention is to prevent erroneous detection due to jumping of a coin against the guide by preventing a coin from colliding against the guide when the coin is delivered from the coin-separating and feeding device to the guide of a coin discriminating device.
A second object of the present invention is to manufacture a device of the first object inexpensively.
In order to achieve the above objects, a coin-separating and feeding device according to a first aspect of the present invention is configured in the following manner.
A coin-separating and feeding device where, after coins are sorted individually by holding the coins in sorting recesses opened on an upper side and a peripheral edge side thereof on an upper face of a rotating disk arranged in an inclination state, the coins are fed out to a coin discriminating device. Each of the sorting recesses have a peripheral opening and an upper face opening formed by a sorting recess groove extending from approximately the center of the rotating disk toward an outer peripheral edge thereof. A mover member is disposed so as to reciprocate linearly between a sorting position on a bottom portion of the sorting recess groove and a pushing-out position on a peripheral edge side of the rotating disk within the sorting recess groove. The mover member has a pushing edge facing the peripheral opening, and forms a portion of a holding recess surrounded by a left side wall and a right side wall of the sorting recess. An arc-shaped restrictor surrounds an outer periphery of the rotating disk, and the sorting recess, holding a coin, is configured, in dimensions, such that when the mover member is positioned at the sorting position, only one of the largest coins can be positioned in the holding recess and two smallest coins cannot be positioned therein in a parallel fashion, wherein, after the mover member is moved linearly toward the pushing-out position on the peripheral edge side in a predetermined phase of the rotating disk and after the mover member stays at the pushing-out position for a predetermined period of time, the mover member is driven by a driving device for moving the mover member back to the sorting position linearly. A driving device comprises a ring-like plate-shaped cam fixedly arranged adjacent the rotating disk, and a pair of cam followers are positioned inside and outside the plate-shaped cam and integrally mounted on the mover member.
With this configuration, coins can be received in the sorting recesses one by one to be sorted individually according to the rotation of the rotating disk. Specifically, since the sorting recess is a recess configured such that only one of the plurality of coins to be sorted can be held by the pushing edge of a pusher, a left side wall, and a right side wall of the recess in dimensions so that even if the coin is the smallest coin, two of them are prevented from being held within the sorting recess.
When the pusher is moved to the pushing-out position, which is a delivery position to the coin discriminating device, the mover member is positioned at the sorting position on the bottom of the sorting recess groove and is moved linearly toward the pushing-out position in a direction of the peripheral edge side of the rotating disk, namely, in a radial direction, and the mover member is moved such that the coin is pushed out of the sorting recess by the arc-shaped pushing edge of the mover member. By this movement of the mover member, the coin is securely pushed out in the peripheral direction of the rotating disk to be delivered to the coin discriminating device.
Further, the mover member is moved by the driving device composed of the ring-like plate-shape cam and the pair of cam followers positioned inside and outside of the plate-shape cam, respectively. In other words, the moving velocity of the mover member can be carefully controlled by the profile of the plate-shaped cam.
Therefore, by setting the profile of the plate-shaped cam appropriately, a coin which has been pushed out by the mover member can be prevented from jumping up at such a degree that it collides against the guide of the coin discriminating device to affect q detection of the coin. By controlling the moving velocity (acceleration) of the mover member when being moved to the pushing-out position at such a velocity that the coin does not collide against the guide, any jumping-up of the coin due to collision against the guide or the like is prevented, so that an appropriate discrimination about a coin can be made possible.
The invention according to a second aspect is directed to the coin-separating and feeding device according to a first aspect of our invention, wherein the mover member includes a pushing part having a pushing edge facing the peripheral opening and a guided portion extending from an intermediate portion of the pushing part toward the rotating disk and then further extending toward the peripheral opening. The guided portion is slidably disposed within a radial linear guide hole formed on an upper face of the rotating disk from adjacent a rotating axis of the rotating disk to extend radially to a periphery of the rotating disk.
With this configuration, the mover member has the pushing part and the guided portion formed integrally, and the guided portion is guided by the guide hole formed in the rotating disk, so that the pushing part is linearly moved in the sorting recess to push and move the coin. Therefore, by forming the guide hole in the rotating disk and integrally constituting a guided portion which is guided according to the guide hole in the mover member, the number of parts can be reduced, which results in a reduction of manufacturing cost.
The invention according to a third aspect is directed to the coin-separating and feeding device wherein the mover member is formed in such a V shape that a mover member bottom edge positioned on the opposite side of the pushing edge gradually comes close to the peripheral edge side from a central portion toward an end portion, and a bottom edge of the sorting recess groove is formed into a similar V shape to the mover member bottom edge.
With this configuration, since the bottom edge of the mover member on the opposite side is formed in the V shape, and it is formed in a similar shape to the bottom edge of the sorting recess groove, even if the bottom edge of the mover member contacts with the bottom edge of the sorting recess, the mover member is still guided to the central portion by the V shape of the bottom edge, so that a problem of a coin drawback occurring due to collision of a coin against an unpredictable portion is removed.
The invention according to a fourth aspect is directed to the coin-separating and feeding device wherein the mover member at the pushing-out position is guided by an upper outer face cam of the plate-shaped cam, while the mover member at the sorting position is guided by a lower inner face cam of the plate-shaped cam.
With this configuration, when the mover member is positioned at the pushing-out position, the mover member is guided by the upper outer face cam of the plate-shaped cam. Specifically, when the mover member is positioned on the upper side of the inclination of the rotating disk, the mover member necessarily contacts with the upper outer face cam of the plate shaped cam by gravity. Therefore, since the pushing-out position of the mover member is restricted by the outer face cam, the pushing-out position of the mover member can be restricted with high accuracy, so that a merit can be obtained in that an unpredictable problem such as collision of the mover member against another part can be avoided. Especially, the pushing and moving position of the mover member at which a coin is delivered to the coin discriminating device is important for each secure delivery of a coin.
Since restriction is performed by the outer face cam constituting the upper side of the plate-shaped cam contacting with the mover member necessarily, the position of the mover member, and therefore, the coin is necessarily restricted by the upper outer face cam of the plate-shaped cam provided in a fixed state. This position can be reproduced accurately each time, and delivery to a coin discriminating device is securely performed each time, so that discrimination of the coin can be made smoothly.
Further, the mover member is guided at the sorting position on the lower side by the lower inner face cam of the plate-like cam. Since the mover member is moved downward by gravity, the mover member contacts with the lower inner face cam of the plate-shaped cam and the position thereof is restricted by the lower inner face cam so that the mover member cannot move below the lower inner face cam. Therefore, the position of the pushing edge of the mover member is restricted by the lower inner face cam of the plate-shaped cam, and a largest diameter of a coin which can be positioned in the sorting recess can be restricted by a distance between the pushing edge and the arc-shaped restrictor arranged adjacent to the outer periphery of the rotating disk. Since the plate-shaped earn is fixed, the pushing edge is prevented from being positioned below a position corresponding to the lower inner face cam, and a proper sorting recess can be formed by arranging the position of the lower inner face cam properly, so that such coins to be sorted can be sorted individually.
Our invention according to a fifth aspect is directed to a coin-separating and feeding device, where, after coins are sorted individually by holding the coins in sorting recesses disposed on an upper face of a rotating disk arranged in an inclination state and having an upper opening and a peripheral opening, the coins are fed to a coin discriminating device. Each of the sorting recesses have a groove-like sorting recess groove extending linearly from adjacent the center of the rotating disk toward an outer peripheral edge thereof. A mover member will reciprocate linearly between a sorting position close to a bottom of the sorting recess groove and a pushing-out position on the periphery side of the sorting recess groove.
Disposed within the sorting recess groove, the mover member has a pushing edge facing the peripheral opening and forms a holding recess surrounded by a left side wall and a right side wall of the sorting recess groove. An inner peripheral face of an arc-shaped restrictor surrounds an outer periphery of the rotating disk, and the holding recess is formed such that when the mover member is positioned at the sorting position, only one largest coin can be positioned in the holding recess but two smallest coins cannot be positioned therein in a parallel fashion, wherein the pushing edge of the mover member is formed in a recessed shape in such a manner that, when the mover member is positioned at the sorting position, the pushing edge is formed in a semi-circular shape slightly larger than the diameter of the largest coin in cooperation with the left side wall and the right side wall such that only one largest coin can be positioned in the semi-circular shape but two smallest coins cannot be positioned therein. After the mover member is moved linearly toward the pushing-out position on the peripheral edge side in a predetermined phase of the rotating disk and subsequently after the mover member stays at the pushing-out position for a predetermined period of time, the mover member is driven by a driving device for linearly moving the mover member back to the sorting position.
The driving device comprises a ring-like plate-shaped cam fixedly arranged on the rotating disk, and a pair of cam followers positioned inside and outside the plate-shaped cam, and integrally mounted on the mover member.
With this configuration, when the mover member is positioned at the pushing-out position, the mover member is guided by the upper outer face cam of the plate-shaped cam. Specifically speaking, when the mover member is positioned on the upper side of the inclination of the rotating disk, the mover member necessarily contacts with the upper outer face cam of the plate-shaped cam by gravity. Therefore, since the pushing-out position of the mover member is restricted by the outer face cam, the pushing-out position of the mover member can be restricted with high accuracy, so that such a merit can be obtained, that an unpredictable problem such as collision of the mover member against another part can be avoided. Especially, the pushing and moving position of the mover member at which a coin is delivered to the coin discriminating device is important for each secure delivery of a coin, and since restriction is performed by the outer face cam constituting the upper side of the plate-shaped earn contacting with the mover member necessarily, the position of the mover member, therefore, the coin is necessarily restricted by the upper outer face cam of the plate-shaped can provided in a fixed state, the position is reproduced accurately each time, and delivery to the coin discriminating device is securely performed each time, which results in such a merit that discrimination of the coin can be made smoothly. Further, the mover member is guided at the sorting position on the lower side by the lower inner face cam of the plate-like cam.
Since the mover member is moved downward by gravity, the mover member contacts with the lower inner face cam of the plate-shaped earn necessarily, and the position thereof is restricted by the lower inner face cam so that the mover member cannot move below the lower inner face cam. Therefore, the position of the pushing edge of the mover member is restricted by the lower inner face cam of the plate-shaped cam, and a largest diameter of a coin which can be positioned in the sorting recess can be restricted by a distance between the pushing edge and the arc-shaped restrictor arranged adjacent to the outer periphery of the rotating disk. Since the plate-shaped cam is fixed, the pushing edge is prevented from being positioned below a position corresponding to the lower inner face cam, and a proper sorting recess can be formed by arranging the position of the lower inner face cam properly, so that such a merit can be obtained that coins to be sorted can be sorted individually.
The invention according to a fifth aspect is directed to a coin-separating and feeding device, where, after coins are sorted individually by holding the coins in sorting recesses disposed on an upper face of a rotating disk arranged in an inclination state and having an upper opening and a peripheral opening, the coins are fed to a coin discriminating device, each of the sorting recess has a groove-like sorting recess groove extending linearly from the center of the rotating disk toward an outer peripheral edge thereof, a mover member reciprocating linearly between a sorting position close to a bottom of the sorting recess groove. A pushing-out position on the periphery side of the sorting recess groove is disposed within the sorting recess groove, the mover member has a pushing edge facing the peripheral opening and forms a holding recess surrounded by a left side wall and a right side wall of the sorting recess groove, and an inner peripheral face of an arc-shaped restrictor surrounding an outer periphery of the rotating disk, and the holding recess is formed such that when the mover member is positioned at the sorting position, only one largest coin can be positioned in the holding recess but two smallest coins cannot be positioned therein in a parallel fashion. The pushing edge of the mover member is formed in a recessed shape in such a manner that, when the mover member is positioned at the sorting position, the pushing edge is formed in a semi-circular shape slightly larger than the diameter of the largest coin in cooperation with the left side wall and the right side wall such that only one largest coin can be positioned in the semi-circular shape but two smallest coins cannot be positioned therein after the mover member is moved linearly toward the pushing-out position on the peripheral edge side in a predetermined phase of the rotating disk and subsequently after the mover member stays at the pushing-out position for a predetermined period of time, the mover member is driven by a driving device for moving the mover member to the sorting position linearly. The driving device comprises a ring-like plate-shaped cam fixedly arranged on the rotating disk, and a pair of cam followers positioned inside and outside the plate-shaped cam, and integrally mounted on the mover member. With this configuration, coins are stirred to be individually sorted into the sorting recesses to be held therein according to rotation of the rotating disk. Specifically, coins are stirred at a position facing a lower portion of the rotating disk by gravity, and are held in the sorting recesses one by one.
The sorting recesses are moved toward the upper portion of the inclination of the rotating disk and after arriving at the uppermost position, the sorting recesses are moved downward. In the course of movement of the mover member to the uppermost position, the cam follower contacts with the outer face cam or the inner face cam of the plate-shaped cam, and it is moved toward the peripheral opening to be sequentially moved from the sorting position to the pushing-out position according to advance to an upper portion of the inclination. At the pushing-out position, the cam follower is guided by the outer face of the plate-shaped cam. The coins sorted into the sorting recesses and held therein are sequentially pushed out of the sorting recesses according to the movements of the mover members so that their positions are defined.
The position of the coin at the pushing-out position of the mover member is a position suitable for delivery of the coin to the coin discriminating device. After the mover member is positioned at the pushing-out position, it is moved downward. The coin which has been pushed out by the mover member is delivered to the coin discriminating device. After release of the coin at the pushing-out position, the mover member is guided by the outer face cam or the inner face cam of the plate-shaped cam, and it is then returned to the lower sorting position while being guided by the lower side inner face cam.
When the cam follower is guided by the lower inner face cam, the pushing edge of the mover member is not moved below the position corresponding to the lower inner face cam. The mover member, when located at the sorting position, hardly changes, so that the size of the sorting recess does not change. Therefore, when the sorting recess is positioned at the lower portion of the rotating disk, the region of the sorting recess is maintained in a proper constant size, so that coins to be sorted can be sorted one by one securely.
Further, since the sorting recess is configured in such a manner that the pushing edge forms a recessed shape such that when the mover member is positioned at the sorting position, the pushing edge takes on a semi-circular shape slightly larger than the diameter of the largest coin in cooperation with the left side wall and the right side wall, therefore, one largest coin can be positioned in the sorting recess but two smallest coins cannot be positioned therein, which results in having coins only sorted into the sorting recesses in a one by one arrangement.
The invention according to a sixth aspect is a coin-separating and feeding device where, after coins are sorted individually by holding the coins in sorting recesses having an upper opening and a peripheral opening on a peripheral side and disposed on an upper face of a rotating disk arranged in an inclination state, the coins are fed to a coin discriminating device. Each of the sorting recesses have a sorting recess groove extending linearly from the center of the rotating disk toward an outer peripheral edge thereof. A mover member can reciprocate linearly between a sorting position close to a bottom of the sorting recess groove and a pushing-out position on a peripheral edge side of the sorting recess groove. The mover member has a pushing edge facing the peripheral opening and forms a holding recess surrounded by a left side wall and a right side wall of the sorting recess. An inner peripheral face of an arc-shaped restrictor surrounds an outer periphery of the rotating disk, and the holding recess is formed such that when the mover member is positioned at the sorting position, only one largest coin can be positioned in the holding recess but two smallest coins cannot be positioned therein in a parallel fashion. In the rotating disk, an upper opening and a peripheral opening, are formed and the sorting recess groove is formed in a groove shape to extend linearly from approximately the center of the rotating disk toward the outer peripheral edge thereof. The rotating disk is constituted by a circular and thick plate-shaped rotating flat circular plate.
A pushing disk is disposed on an inclination upper face of the rotating flat circular plate coaxially with the rotating flat circular plate and forms the sorting recess groove constituted by a left side wall and a right side wall extending from a central portion toward a peripheral direction approximately in parallel with each other, and a bottom edge connecting the left side wall and the right side wall to each other.
When the mover member is positioned at the sorting position, a holding recess at which a coin with a diameter slightly larger than the diameter of a largest coin, to be received can be held, is formed by the pushing edge of the mover member, the left side wall and the right side wall, and the arc-shaped restrictor. A driving device comprises a ring-like plate-shaped cam fixedly arranged adjacent the rotating disk, and a pair of cam followers positioned inside and outside the plate-shaped cam move integrally with the mover member.
With this configuration, coins are stirred to be sorted into the sorting recesses, one by one, according to rotation of the rotating disk. Specifically speaking, coins are stirred at a position facing a lower portion of the rotating disk by gravity, and are positioned and held in the sorting recesses one by one. The sorting recesses are moved toward the upper portion of the inclination according to the rotation of the rotating disk and after arriving at the uppermost position, the sorting recesses are moved downward. In the course of movement of the coins sorted in the sorting recesses to the uppermost position, the cam follower contacts with the outer face or the lower face of the plate-shaped cam and it is sequentially moved from the sorting position to the pushing-out position as the rotating disk advances to the upper portion of the inclination to be finally moved to the pushing-out position.
The pushing-out position is a position suitable for delivering the coin which has been pushed out by the mover member to the coin discriminating device. After the mover member stays at the pushing-out position for a short duration, it is moved downward.
When the mover member is positioned at the pushing-out position, the coin which has been pushed out by the mover member is delivered to the coin discriminating device. After the mover member stays at the pushing-out position, and subsequently after it is moved from the pushing-out position to the sorting position by the outer face cam or the inner face cam of the plate-shaped cam, the mover member is guided by the lower inner face cam and held at the sorting position for a predetermined period of time.
When the cam follower is guided by the lower inner face cam, the pushing edge of the mover member is not moved below a position corresponding to the lower inner face cam. Therefore, a position change of the mover member at the sorting position, does not substantially occur, and the size of the sorting recess does not change. Therefore, when the sorting recess is positioned at the lower portion of the rotating disk, the position of the sorting recess is maintained in a proper constant region, so that coins to be sorted can be sorted into the sorting recesses to be held therein.
Further, since the sorting recess is configured in such a manner that the pushing edge forms a recessed shape such that when the mover member is positioned at the sorting position, the pushing edge takes on a semi-circular shape slightly larger than the diameter of the largest coin in cooperation with the left side wall and the right side wall, wherein one largest coin can be held in the sorting recess but two smallest coins cannot be held therein, so that coins to be sorted can be securely sorted into the sorting recesses one by one.
A coin-separating and feeding device is provided where, after coins are sorted individually by holding the coins in sorting recesses having an upper opening and a peripheral opening on a peripheral side and disposed on an upper face of a rotating disk arranged in an inclination state, the coins are fed to a coin discriminating device. Each of the sorting recesses has a sorting recess groove extending linearly from adjacent the center of the rotating disk radially outward toward an outer peripheral edge thereof. A mover member is mounted in the sorting groove and can reciprocate linearly between a sorting position close to a bottom of the sorting recess groove and a pushing-out position on a peripheral edge side of the sorting recess groove.
The mover member has a pushing edge facing the peripheral opening and forms a holding recess between a left side wall and a right side wall of the sorting recess. An inner peripheral face of an arc-shaped restrictor surrounds an outer periphery of the rotating disk, and the holding recess is formed such that when the mover member is positioned at the sorting position, only one largest coin can be positioned in the holding recess but two smallest coins cannot be positioned therein in a parallel fashion, wherein, in the rotating disk, the upper opening and the peripheral opening on the peripheral side are formed and the sorting recess groove is formed in a groove shape to extend linearly from adjacent the center of the rotating disk toward the outer peripheral edge thereof.
The rotating disk is constituted by a circular and thick plate-shaped rotating flat circular plate. A pushing disk is disposed on an inclination upper face of the rotating flat circular plate coaxially with the rotating flat circular plate to form sorting recess grooves constituted by respective left side walls and right side walls extending from a central portion toward a peripheral direction approximately in parallel with each other. A bottom edge connects the left side wall and the right side wall to each other.
When the mover member is positioned at the sorting position, a holding recess is formed with a diameter slightly larger than the diameter of a largest coin to be received. The coin can be held by the pushing edge of the mover member, the left side wall and the right side wall, and the arc-shaped restrictor. A driving device comprises a ring-like plate-shaped cam fixedly arranged on the rotating disk, and a pair of cam followers are positioned inside and outside the plate-shaped cam integrally with the mover member.

Incidentally, in this embodiment, since the storing bowl 124 has a function of storing coins C and a function of forming holding recesses 130 in cooperation with sorting recesses 132 described later, an arc-shaped restrictor 131 is disposed so as to enclose at least a periphery of a lower portion of the rotating disk 122 to form the holding recesses 130. The storing bowl 124 can be configured to be continuous to the arc-shaped restrictor 131 for storing coins C or can be separate components from each other.

Next, the rotating disk 122 will be described mainly with reference to
The rotating disk 122 is composed of a rotating flat circular plate 134 having a predetermined thickness and serving as a base, a pushing disc 138 is fixed on an upper face of 154 of the rotating flat circular plate 134 coaxially with the rotating flat circular plate 134 and comprising a plate formed in a Y shape by three projection portions 136a, 136b, and 136c arranged at equal intervals, see
Incidentally, in the specification, the term “sorting recesses 132a, 132b and 132c” represents individual sorting recesses, while the term “sorting recesses 132” represents all the sorting recesses 132a, 132b and 132c. This also holds true for other constituent elements.
First, the rotating flat circular plate 134 will be described in detail mainly with reference to
The rotating flat circular plate 134 has such a function that it has the pushing disc 138 disposed on the side of an upper face thereof and a plate-shaped cam 146 is disposed on the side of a back face thereof and described later. Circular plate 134 is formed with a driven gear 148 on a peripheral face thereof, and it is formed with guide holes 152 through which the movers 142 are guided.
The rotating flat circular plate 134 has a disc-shaped member with a predetermined thickness, and it is preferably integrally formed of resin having abrasion resistance. This is because, by molding a complicated shape at one time, manufacture at a low cost is achieved while a predetermined precision is being maintained. However, the rotating fiat circular plate 134 can be made of metal in order to further improve abrasion resistance.
The upper face 154 of the rotating flat circular plate 134 is formed as a flat face, so that it can come in direct surface-contact with a face of a coin C. The term “surface-contact” used here means the case where surfaces come in close contact with each other completely but also the case that they come in rough surface-contact with each other so that the upper face 154 can exert such a function that one coin C is sorted into each of the sorting recesses 132.
A peripheral face 156 of the rotating flat circular plate 134 is formed to have a diameter slightly smaller than that of the upper face 154, the driven gear 148 for gear drive is foliated on the peripheral face 156, and the driven gear 148 meshes with a drive gear (not shown) rotated by a reducer 162 (
Next, the pushing disc 138 will be described with reference to
The pushing disc 138 provides the sorting recesses 132 in cooperation with the movers 142 and the rotating flat circular plate 134, and it has a function of moving coins C held in the sorting recesses 132 one by one in a pushing manner.
The pushing disc 138 is formed in a disc shape having a diameter roughly smaller than that of the rotating flat circular plate 134, and is formed in a Y shape by three projection portions 136a, 136b and 136c. The pushing disk 138 is brought in close contact with the upper face 154 of the rotating flat circular plate 134 coaxially with the rotating disk 134 and is fixed thereto by utilizing mount holes 164. Sorting recesses 132a, 132b and 132c are formed between the projections portions 136a, 136b and 136c. The reason why the pushing disc 138 is formed in a Y shape is because three sorting recesses 132 are formed.
Therefore, when two sorting recesses 132 are formed, the pushing disc 138 is formed in a H shape, and when four sorting recesses 132 are formed, the pushing disc 138 is formed in a cross shape. The number of sorting recesses 132 is determined mainly depending on a desired processing rate of coins.
Since the pushing disc 138 stirs coins, to push and move them, it is preferably produced from a metal plate, but it may be molded integrally with the rotating flat circular plate 134 from resin having abrasion resistance or alternatively according to a sintering process.
The thickness of the pushing disc 138 is formed to be slightly thinner than a thinnest coin C of coins C to be treated as true coins. This is because, even if two thinnest coins C overlap with each other, only a coin C positioned on a lower side is supported by the pushing disc 138 while a coin C riding on the former coin is not supported thereby. Since this embodiment is for euro coins, the pushing disc 138 is formed of a stainless steel plate having a plate thickness thinner than a one-cent coin, for example, 1.5 mm.
Since the projection portions 136a, 136b and 136c are formed to extend from a rotating axis 166 of the pushing disc 138 having a disc shape wholly in a peripheral direction at equal intervals of 120° and all of them have the same shape, the projection portion 136a is explained on behalf of the projection portions 136a, 136h and 136c and portions of the projection portions 136b and 136c identical to those of the projection portion 136a are attached with same reference numerals as those of the projection portion 136a and explanation thereof is omitted.
In
The proximal end portion 168a has a rectangular plate shape having a constant first width Wa and a left side edge 174l thereof which constitutes a linear right bottom edge 176r positioned on the right side of a sorting recess groove 182c, to be described later, while a right side edge 174r constitutes a linear left bottom edge 176l positioned on the left side of a sorting recess groove 182a. The right side edge 174r and the left side edge 174l have the same length and they constitute a bottom edge 184a of the sorting recess groove 182a formed into a V shape for forming an angle of about 120°.
The distal end portion 172a is formed in a fan shape gradually expanded. Thereby, a right base wall 188r is continuous at an obtuse angle regarding the left side edge 174l and a left base wall 188l are formed to be at a predetermined angle with a center line Ca. The left base wall 188l and the right base wall 188r are formed to be bilaterally symmetrical to the center line Ca.
An outer peripheral edge 194a of the distal end portion 172a is formed in an arc shape having its center at the rotating axis 166, and provides a structure where an arc-shaped outer peripheral upper face 195 having a predetermined width is exposed between the outer peripheral edge 194a and an outer peripheral edge of the rotating flat circular plate 134.
The outer peripheral upper face 195 enables a coin to be smoothly delivered to a knife 196, described later, by an arrangement that a distal end of the knife 196 is caused to overlap with the outer peripheral upper face 195, thus, the distal end of the knife 196 overlaps with an upper side of the outer peripheral upper face 195. A detection guide 107 is formed so as to follow the knife 196.
A circular hole 202 is formed on the rotating flat circular plate 134 about the rotation axis line thereof so as to correspond to a circular hole 198 of the pushing disc 138 about the rotating axis 166, so that the pushing disc 138 is rotatably attached to a fixing shaft (not shown) via a bearing.
A slot 175a is formed to extend from a boundary between a left curved wall 1921 and a left distal end side wall 201l positioned close to the outer peripheral edge 194a of the distal end portion 172a in parallel with a tangential line of the outer peripheral edge 194a, and a projection for lifting up 193a is formed on the side of the outer peripheral edge 194a from the slot 175a, and a distal end of the lifting-up projection 193a is bent so as to be elevated from the upper face 154. By the lifting-up projection 193a, a coin C riding thereon is promoted to drop to provide a separation effect of the coin C, in other words, such an effect that sorting of the coin C is enhanced.
Next, the sorting recess groove 182a will be described.
The sorting recess groove 182a is a recess groove where the mover 142a is movable towards the peripheral direction of the rotating disk 122, and it forms the sorting recess 132a in cooperation with the mover 142a. The sorting recess groove 182a is defined by a bottom edge 184, a left side wall 200l, and a right side wall 200r. The left side wall 200l is composed of the left base wall 188l, the left curved wall 192l, and the left distal end side wall 201l, while the right side wall 200r is composed of the right base wall 188r, the right curved wall 192r, and right distal end side wall 201r.
The left side wall 200l is composed of a left curved wall 192l that is curved at a curvature slightly larger than the diameter of the largest coin to be received. The left base wall 188l and the left distal end side wall 201l are formed in parallel with the left base wall 188l following the left curved wall 192l.
The right side wall 200r is composed of the right curved wall 192r formed to have the same curvature as that of the left curved wall 192l. The right base wall 188r and the right distal end portion 200r are formed in parallel with the right base wall 188r following the right curved wall 192r. Therefore, the sorting recess groove 182a is formed to have a symmetrical shape regarding the center line Ca.
The left side wall 200l is composed of the left base wall 188l, the left curved wall 192l, and the left distal end wall 201l, while the right side wall 200r is composed of the right base wall 188r, the right curved wall 192r, and the right distal end wall 201r, so that the sorting recess groove 182a is formed in an arrow shape in the direction toward the rotating axis 166 in appearance by the bottom edge 184, the left side wall 200l, and the right side wall 200r.
Since this embodiment is for euro coins, the left curved wall 1921 and the right curved wall 192r are set to have a curvature corresponding to 27 mm of a diameter slightly larger than 25.75 mm which is the diameter of the two-euro coin which has the largest diameter, but the curvature can be set properly if the function of the sorting recess groove 132a can be exerted.
The reason why the left distal end side wall 201l and the right distal end side wall 201r are formed to be parallel with each other is because a coin C can be smoothly pushed out of the sorting recess 132a.
Next, the guide hole 152a for the mover 142a will be described.
The guide hole 152a has a function of guiding the mover 142a so as to move linearly in parallel with the axis of the sorting recess groove 182a, therefore the center line Ca. The guide hole 152a is formed as an elongated hole so as go through the rotating flat circular plate 134 vertically and extend from the rotating axis 166 radially such that a long axis thereof extends on the center line Ca. In this embodiment, as shown in
The guide groove 152 includes mover guide longholes 206a, 206b, and 206c formed linearly on the center lines Ca. Since these mover guide longholes 206a, 206b, and 206c all have the same structure, the mover guide longhole 206a is explained on behalf of these longholes, and portions of the mover guide longholes 206b, and 206c corresponding to those of the mover guide longhole 206a are attached with the same reference characters and their explanation thereof is omitted.
The mover guide longhole 206a has a function of moving the mover 142a along the sorting recess groove 182a, more specifically, a function of linearly moving the mover 142 along the sorting recess groove 182a from a sorting position sp near a bottom edge 184 of the sorting recess groove 182a toward a pushing-out position pp and guiding the mover 142 such that the mover 142 returns from the pushing-out position pp to the sorting position sp linearly.
The mover guide longhole 206a is arranged such that an extending direction of the sorting recess groove 182a coincides with the longitudinal direction of the mover guide longhole 206a in an intermediate portion (center portion) of the sorting recess groove 182a. Such an arrangement is adopted so that a longhole center line of the mover guide longhole 206a overrides the center line Ca going through the top of the bottom edge 184 constituting the sorting recess groove 182a.
As shown in
The lower side groove 212a is formed and defined between a lower side left side wall 212l and a lower side right side wall 212r formed parallel to each other, and a distance between the lower side left side wall 212l and the lower side right side wall 212r is a third width Wu. The second width Wb of the upper side groove 208a is larger than the third width Wu of the lower side groove 212u, and a left guide face 216l and a right guide face 216r parallel with the upper face 154 are formed between the upper side groove 208a and the lower side groove 212u.
The pushing disc 138 is fixed to the upper face 154 of the rotating flat circular plate 134 by screws 140 penetrating the rotating flat circular plate 134 coaxially, so that the pushing disc 138 and the rotating flat circular plate 134 are integrated with each other.
Next, the mover 142 will be described with reference to
The mover 142 has a function of pushing and moving a coin C held in the sorting recess 132 in a radial movement towards the peripheral direction of the rotating disk 122, specifically, a function of, when the mover 142 is positioned at the sorting position sp, forming the sorting recess 132 in cooperation with the sorting recess groove 182 and further forming the holding recess 130 in cooperation with the arc-shaped restrictor 131 arranged near the outer periphery of the rotating disk 122.
Since the mover 142 is only required to form the holding recess 130 holding one coin C of a largest coin LC to a smallest coin SC in cooperation with the sorting recess 182 and the arc-shaped restrictor 131 and to push and move the coin C in the peripheral direction of the rotating disk 122, it may be provided with at least an arc-shaped pushing edge 144, and though the shape may have alternative shapes, the mover 142 is formed in an arc shape in plan view.
As shown in
The mover 142a includes a pushing part 219a and a passive 222a. As shown in
The left inner side edge 217l and the right inner side edge 217r constitute a V-shaped mover bottom edge 220. Further, the thickness of the pushing part 219a is formed to have the same thickness as that of the pushing disc 138. Like the pushing disc 138, this is because, when two thinnest coins C are stacked one on each other, an upper side coin C is not supported and is caused to drop by its own weight. However, unless the function of the pushing part 219a is damaged, the thickness thereof can be made thinner than the pushing disk 138.
The left side wall 186l facing the left base wall 188l of the pushing part 219a and the right side wall 186r facing the right base wall 188r are formed to have small angles to the left base wall 188l and the right base wall 188r, respectively, such that a clearance between the left side wall 186l and the right side wall 186r increases according to coming close to a mover bottom edge 220 (bottom edge 184). Thereby, even if the mover 142a is shifted due to a reaction force from a coin C so that the left side edge 186l and the right side wall 186r come in frictional contact with the left base wall 188l or the right base wall 188r, respectively, the mover 142a can move without receiving frictional resistance while a point contact is maintained.
An edge positioned on the opposite side of the left inner side edge 217l and the right inner side edge 217r is formed with an arc-shaped pushing edge 144a. The pushing edge 144a is formed to have a curvature slightly larger than a diameter of the largest coin. LC to be received therein.
Next, the pushing edge 144a will be described.
When the mover 142 is positioned at the sorting position sp, the pushing edge 144a has a function of forming the sorting recess 132a in cooperation with the sorting recess groove 182a and forming the holding recess 130a in cooperation with the arc-shaped restrictor 131 arranged near the outer periphery of the rotating disk 122. The pushing edge 144a is formed in such an arc shape as to be recessed toward a peripheral opening 190.
In this embodiment, since a passive support part 222a is formed from an intermediate portion of the pushing edge 144a to extend downward, the pushing edge 144a is sectioned to a left pushing edge 221l and a right pushing edge 221r at the center thereof, and it is formed to be laterally symmetrical regarding the center of the center line Ca. Therefore, a coin C is pushed and moved by one or both of the left pushing edge 221l and the right pushing edge 221r according to the diameter thereof and the situation thereof.
Next, the passive support part 222a will be described.
The passive support part 222a has a function of supporting a driven device 226a, in other words, a function of transmitting movement of the driven device 226a based upon the plate-shaped cam 146 to the pushing part 219a.
The passive support part 222a is formed so as to project from an intermediate portion of the pushing edge 144a of the mover 142a. The passive support part 222a is formed to have a width slightly narrower than the second width Wb of the upper side groove 208a, so it can be inserted into the upper side groove 208a. A mount part 224a is formed by bending the passive support part 222a from a central portion of the pushing edge 144a of the mover 142a downward such that a length thereof is slightly longer than the thickness of the pushing part 219a and then bending the passive support part 222a in parallel with the pushing part 219a. In other words, the pushing part 219a and the mount part 224a are formed to have a crank shape in a side view, as shown in
Though the pushing part 219a and the passive support part 222a can be integrally formed by a sheet metal forming, they can also be integrally casted or molded from resin having abrasion resistance, and in this case, the pushing edge 144a can be formed into a continuous arc shape.
Next, a driving device 225 for the mover 142a will be explained.
The driving device 225 has a function of positioning the mover 142 to a predetermined position at a predetermined timing. The driving device 225 includes a driven device 226 and the plate-shaped cam 146. First, the driven device 226a will be described. The driven device 226a has a function of moving the mover 142a to a predetermined position at a predetermined timing according to the shape of the plate-shaped cam 146.
In this embodiment, the driven device 226a is a cam follower device 228a integrally provided on the mover 226a, but it is not limited to the cam follower device 228a and any device having the same function can be used as the driven device 226a.
The cam follower device 228a includes a first supporting part 232a extending from the pushing part 219a downward, a second supporting part 234a extending from a distal end portion of the passive support part 222a downward in parallel with the first supporting part 232a, and a first cam follower 236a and a second cam follower 237a attached at distal ends of the first supporting part 232a and the second supporting part 234a.
The first supporting part 232a and the second supporting part 234a are arranged such that their axes are positioned on the center line Ca, and a first intermediate portion 242a of the first supporting part 232a and a second intermediate portion 244a of the second supporting part 234a penetrate the guide hole 152a (the mover guide hole 206a (the upper side groove 208a and the lower side groove 212a)).
The first supporting part 232a will be described mainly with reference to
A first guided part 250a having a diameter slightly smaller than that of the first large-diameter part 248a is formed below the large-diameter part 248a, and it is formed to have a length equal to the depth of the lower side groove 212a. A first shaft part 252a having a diameter slightly smaller than that of the first guided part 250a is formed below the first guided part 250a, and a length thereof is set slightly longer than the thickness of a cam roller 238a which is the first cam follower 236a.
A first retainer attaching part 254a having a diameter equal to that of the first shaft part 252a is formed at a lower end portion of the first shaft part 252a, and a ring-like first retainer attaching groove 256a is formed at the first retainer attaching part 254a, and an inward click of a first retainer 258a which is a known E-type snap ring is retained at the ring-like first retainer groove 256a so that the first cam follower 236a is prevented from dropping off.
The first upper end part 246a is inserted into a first circular hole 262a formed in the mover 142a such that an axial center thereof is positioned on the center line Ca, and it is firmly fixed to the pushing part 219a by such a swaging process that a distal end of the first upper end part 246a is crashed by a punch.
Next, the second supporting part 234a will be described. The second supporting part 234a is formed in a stepped round bar shape, and a second upper end part 264a is formed to have a diameter smaller than a second large-diameter part 266a and it is formed to have a length slightly larger than the thickness of the mover 142a. The second large-diameter part 266a is formed following the second upper end part 264a on a lower side thereof, and the length thereof is set such that a length obtained by adding the thickness of the passive 222a and the thickness of the second large-diameter part 266a is equal to the depth of the upper side groove 208a.
A second guided part 272a having a diameter slightly smaller than that of the second large-diameter part 266a is formed below the second large-diameter part 266a, and it is formed to have a length equal to the depth of the lower side groove 212a. A second shaft part 274a having a diameter slightly smaller than that of the second guided part 272a is formed below the second guided part 272a, and it is formed to have a length slightly longer than the thickness of the cam roller 238a which is the second earn follower 237a. A second retainer attaching part 276a having a diameter equal to that of the second shaft part 274a is formed below the second shaft part 274a, a ring-like second retainer attaching groove 278a is formed on the second retainer attaching part 276a, so that an inward click of a known second retainer 280a is retained at the second retainer attaching part 276a.
When the mover 142a is attached to the rotating flat circular plate 134, the attaching is achieved by sequentially inserting the lower portions of the first supporting part 232a and the second supporting part 234a which are not attached with the first cam follower 236a and the second cam follower 237a into the upper side groove 208a and the lower side groove 212a, then fitting the first cam follower 236a and the second cam follower 237a on the first shaft part 252a and the second shaft part 274a, respectively, and thereafter fitting the first retainer 258a and the second retainer 280a into the first retainer attaching groove 256a and the second retainer attaching groove 278a, respectively.
Setting is performed such that the position of the mover 142a to the rotating flat circular plate 134 in a vertical direction is restricted by a back surface of the mover 142a and surfaces of the first cam follower 236a and the second cam follower 237a. Accordingly, the mover 142a is moved in a state where it comes in substantially-close contact with the upper face 154 of the rotating flat circular plate 134.
The position of the mover 142a to the rotating flat circular plate 134 in a normal direction is restricted by the first guided part 250a and the second guided part 272a, and the lower side groove 212a such that the mover 142a is not oscillated substantially from side to side. The mover 142a is reciprocated linearly in the longitudinal direction of the sorting recess groove 182a in a state where it is not substantially moved in a widthwise direction of the sorting recess groove 182a.
A clearance D1 is set between the circumferential faces of the first cam follower 236a and the second cam follower 237a. The plate-shaped cam 146 is disposed in the clearance D1. In other words, the plate-shaped cam 146 is sandwiched between the first cam follower 236a and the second cam follower 237a.
The mover 142a is linearly reciprocated between the sorting position sp and the pushing out position pp at a predetermined timing by the plate-shaped cam 146. The sorting position sp indicates a state where the mover 142a is positioned at a bottom portion of the sorting recess groove 182a, it indicates positions of the movers 142a and 142b in
When the mover 142a is positioned at the sorting position sp, the left pushing edge 221l, the right pushing edge 221r, the left curved wall 192l, and the right curved wall 192r are formed to be approximately positioned on a virtual circle vc. The virtual circle vc has a diameter slightly larger than a diameter of a largest coin to be received. In this case, a peripheral edge of the virtual circle vc positioned on the opposite side of the mover 142a is set to come in contact with an inner edge of the storing bowl 124, therefore, the arc-shaped restrictor 131.
The pushing-out position pp indicates a position at which left and right distal ends of the pushing edge 144a of the mover 142a have come close to an outer circumferential edge of the pushing disc 138 after the mover 142a has been moved along the guide hole 204.
Next, the sorting recess 132a will be described mainly with reference to
When the mover 142a in the sorting recess groove 182a is positioned at the sorting position sp, the sorting recess 132a is a semi-circular recessed portion defined by the pushing edge 144a, the left curved wall 192l, the left distal end side wall 201l, the right curved wall 192r, and the right distal end side wall 201r. Therefore, the sorting recess 132a is a recessed portion having a peripheral opening 190 and an upper face opening 191, and it is formed to have a depth slightly shallower than the thickness of a thinnest coin to be sorted.
The sorting recess 132a constitutes the holding recess 130 in cooperation with the arc-shaped restrictor 131, in this embodiment, an inner face of the storing bowl 124, and only one coin of the largest coin LC to the smallest coin SC to be sorted is held in the holding recess 130.
The expression “a coin is held” means that a surface or a back surface of a coin C is in surface-contact with the upper face 154 in the sorting recess 132a. In other words, two coins are not held in the sorting recess 132a even if they are smallest coins, and they are partially stacked one on another necessarily, so that when the partially stacked coins C are moved upward according to rotation of the rotating disk 122, a coin C of the coins C positioned on the upper side drops due to gravity. The storing bowl 124 is disposed in a range where the mover 142a starts to move from the sorting position sp to the pushing-out position pp. Specifically, the storing bowl 124 (arc-shaped restrictor 131) is disposed around the rotating disk 122 approximately below a horizontal line passing through the axis 166.
Next, the holding recess 130a will be described.
The holding recess 130a is a recessed portion formed on the rotating disk 122 and holding only one coin C to be sorted. As described above, the holding recess 130 is a semi-circular recess which is composed of the sorting recess 132 and the arc-shaped restrictor 131, which has the upper face opening 191 opened at an upper face thereof, whose outer periphery is substantially enclosed by the arc-shaped restrictor 131, and whose lower face is dosed.
Next, the plate-shaped cam 146 will be described with reference to
The plate-shaped cam 146 has a function of moving the mover 142 to a predetermined position at a predetermined timing. The plate-shaped cam 146 in this embodiment is formed in an egg-shaped ring shape and has a predetermined thickness, an end face thereof is fixed to a disc-shaped mount plate 284, and the mount plate 284 is fixed to a fixing portion (not shown) in a parallel arrangement with the rotating disk 122. In other words, the plate-shaped cam 146 is provided in a static state and the rotating disk 122 is rotated relative to the plate-shaped cam 146.
The plate-shaped cam 146 is formed to be laterally symmetrical to a cam center line ccl passing through the rotating axis 166 and inclined slightly leftward in front view. Specifically, a lower inner face cam 288i having a lower first radius r1 and a lower outer face cam 288o having a lower second radius r2 slightly larger than the lower first radius r1 are formed around the rotating axis 166 in a range of a first angle α1 which is positioned below the rotating axis 166. A difference between the lower second radius r2 and the lower first radius r1 is equal to the thickness of the plate-shaped cam 146.
The lower first radius r1 is set such that when the first cam follower 236a comes in contact with the lower inner face cam 288i, the mover 142a is held at the sorting position sp. In other words, when the mover 142a faces a lower portion of the rotating disk 122, namely, the storing chamber 128, it is held at the sorting position sp.
An upper inner face cam 292i having an upper first radium r3 and an upper outer face cant 292o having an upper second radius r4 are formed around the rotating axis 166 in a range of a second angle α2 which is positioned above the rotating axis 166.
A difference between the upper first radius r3 and the upper second radius r4 is equal to the difference between the lower second radius r2 and the lower first radius r1. In other words, the thickness of the plate-shaped cam 146 is set to be equal over a whole circumference.
The upper second radius r4 is set such that when the second cam follower 237a comes in contact with the upper outer face cam 292o, the mover 142a is held at the pushing-out position pp. In other words, when the mover 142a is positioned at an upper portion of the rotating disk 122, namely, near the knife 196, it is maintained at the pushing-out position pp.
Left side ends of the lower inner face cam 288i and the upper inner face cant 292i are connected to a linear left inner face can 294i connecting them gently and the upper inner face cam 292i and the linear left inner face cam 294i are connected by an arc-shape upper connecting inner face cam 295i, while left side ends of the lower outer face cam 288o and the upper outer face cam 292o are connected a left outer face cam 294o connecting them gently and the upper outer face cam 292o and the left outer face cam 294o are connected by an arc-shaped upper connecting outer face cam 295o.
Right side ends of the lower inner face cam 288i and the upper inner face cam 292i are connected to a linear right inner face cam 296i connecting them gently, and the lower inner face cam 288i and the right inner face cam 296i are connected by an arc-shaped lower connecting inner face cam 297i, while right side ends of the lower outer face cam 288o and the upper outer face cam 292o are connected to a linear right outer face cam 296o connecting them gently, and the lower outer face cam 288o and the right outer face cam 296o are connected by an arc-shaped lower connecting outer face cam 287o.
The plate-shaped cam 146 is disposed to be positioned in a clearance D1 between the first can follower 236a and the second cam follower 237a. In this embodiment, the first cam follower 236a and the second cam follower 237a are set to be guided at predetermined periods by the outer face cam 286o and the inner face cam 286i of the plate-shaped cam 146.
Thereby, when the first cam follower 236a or the second cam follower 237a is selectively guided by the right inner face cam 296i and the right outer face cam 296o, the upper connecting inner face cam 295i and the upper connecting outer face cam 295o, and the lower connecting inner face cam 297i and the lower connecting outer face cam 297o, respectively, the movers 142a to 142c are sequentially moved from the sorting position sp to the pushing-out position pp.
When the first cam follower 236a or the second cam follower 237a is selectively guided by the left inner face cam 294i or the left outer face cam 294o, the upper connecting inner face cam 295i and the upper connecting outer face cam 295o, and the lower connecting inner face cam 297i and the lower connecting outer face cam 297o, respectively, the movers 142a to 142c are sequentially moved from the pushing-out position pp to the sorting position sp.
Therefore, since the first cam follower 236a and the second cam follower 237a can be positioned on a line inclined relative to the plate-shaped cam 146, the clearance D1 is set larger than the thickness of the plate-shaped cam 146 such that smooth guiding can still be performed.
The profile of the plate-shape cam 146 is shown in
First, the first cam follower 236a or the second cam follower 237a is guided at a relatively slow speed by the upper connecting inner face cam 295i or the upper connecting outer face cam 295o, so that the mover 142a is moved from the pushing-out position pp toward the sorting position sp.
Subsequently, since the first cam follower 236a or the second cam follower 237a is guided by the left outer face cam 294o or the left inner face cam 294i, the mover 142 is moved toward the sorting position sp at a constant speed faster than the moving speed in the upper connecting inner face cam 295i or the upper connecting outer face cam 295o.
Next, since the first cam follower 236a or the second cam follower 237a is guided by the lower connecting inner face cam 297i or the lower connecting outer face cam 297o, the mover 142 is moved toward the sorting position sp while it is continuously decelerated from the moving speed of the left outer face cam 294o or the left inner face cam 294i.
Since the first cam follower 236a is guided at the first radius r1 closest to the rotating axis 166 by the lower inner face cam 288i, the mover 142 is rotated in a counterclockwise direction while it maintains the sorting position sp.
Subsequently, the first cam follower 236a or the second cam follower 237a is continuously accelerated by the lower connecting inner face cam 297i or the lower connecting outer face cam 297o to be moved from the sorting position sp toward the pushing-out position pp.
Further, since the first cam follower 236a or the second cam follower 237a is moved with a constant acceleration by the right outer face cam 296o or the right inner face cam 296i, the mover 142 is moved toward the pushing-out position pp at a high speed.
When further rotated, since the first cam follower 236a or the second cam follower 237a is guided by the upper connecting inner face cam 295i or the upper connecting outer face cam 295o, the mover 142a is moved toward the pushing-out position pp by the right outer face cant 296o or the right inner face cam 296i while being decelerated to a slow speed.
When further rotated, the first cam follower 236a or the second cam follower 237a is guided by the upper outer face cam 292, so that the mover 142 is moved in the counterclockwise direction while it maintains the pushing-out position pp.
Next, movement of the mover 142 performed by the plate-shaped cam 146 will be described based upon the case where the mover 142 is positioned at the sorting position sp with reference to
When the rotating disk 122 is rotated, coins c stored in the storing bowl 124 are stirred by steps due to the pushing disc 138 or the like, and after surfaces or back surfaces of the coins C advance from the upper face opening 191 to the sorting recess 132, they come in surface contact with the upper face 154 to be held in the sorting recesses 132a, 132b, and 132c one by one. In other words, coins having a diameter exceeding a diameter to be received cannot come in surface contact with the upper face 154 between an inner edge of the storing bowl 124, and each of the pushing edges 144a, 144b, and 144c, so the they are not held in the respective sorting recesses 132a, 132b, and 132c.
Similarly, smallest coins Sc to be received are not held in the respective sorting recesses 132a, 132b, and 132c two by two in parallel, and one of the two small-diameter (smallest-diameter) coins SC is partially stacked on the other in each of the sorting recesses 132a, 132b, and 132c, so that when each of the sorting recesses 132a, 132b, and 132c is moved upward, the coin SC partially stacked on the coin SC held in each of the sorting recesses 132a, 132b, and 132c cannot be supported by the pushing disc 138, thereby dropping due to its own weight. In other words, coins with a diameter to be sorted are sorted and held in the sorting recesses 132a, 132b, and 132c one by one.
As shown in
When the rotating disk 122 is rotated in the counterclockwise direction while the mover 142a maintains the sorting position sp, a coin C held in the holding recess 130a is pushed and moved by the right curved portion 192r or the right distal end side wall 201r constituting a rear position side of the sorting recess 132a in the rotating direction and is rotated in the counterclockwise direction following the rotation of the rotating disk 122 while being guided by the arc-shaped restrictor 131 (storing bowl 124).
When the rotating disk 122 is further rotated from the state shown in
Even in this case, since the distance D1 between the first cam follower 236a and the second cam follower 237a is wider than the plate-shaped cam 146, the mover 142a is still moved smoothly while being guided by the right inner face cam 296i or the right outer face cam 296o.
When the rotating disk 122 is further rotated, the first cam follower 236a and the second cam follower 237a reach a phase guided by the upper outer face cam 292o of the plate-shaped cam 146, and the mover 142a is positioned at the pushing-out position pp (
In addition, since the position of the mover 142a is held at the pushing-out position pp by the upper outer face earn 292o, the coin C which has been pushed out by the mover 142a takes a position suitable for delivery continuously.
When the rotating disk 122 is further rotated, after the first cam follower 236a and the second cam follower 237a are guided by the upper connecting inner face cam 295i or the upper connecting outer face cam 295o of the plate-shaped cam 146, they are guided by the left inner face cam 294i and the left outer face cam 294o, so that the mover 142a is gradually moved from the pushing-out position pp toward the sorting position sp. Even in this case, since the distance D1 between the first cam follower 236a and the second cam follower 237a is sufficiently wider than the plate-shaped cam 146, the mover 142a is smoothly moved while being guided by the left inner face cam 294i or the left outer face cam 294o.
Next, the operation of this embodiment will be described mainly with reference to
When the rotating disc 122 is rotated from the state shown in
In
When the rotating disk 122 is further rotated in the counterclockwise direction, as shown in
While the coin C maintains the pushed-out position, it is pushed by the impeller 105 to be pushed against the knife 196, and the physical property of the coin C is then detected by a sensor (not shown) while the coin C is being moved along the guide 107. The coin discriminating device 106 performs truth/false discrimination and denomination discrimination of the coin C based upon the detected physical property.
When the rotating disk 122 is further rotated in the counterclockwise direction, the first cam follower 236a and the second cam follower 237a are guided by the upper connecting outer face cam 295o and the upper connecting inner face cam 295i, and the left inner face cam 294i and the left outer face cam 294o to be moved from the pushing-out position pp toward the sorting position sp.
