The present invention relates to a coin sorting device that sorts a plurality of coins having different diameters by type.
The present invention also relates to a coin sorting / counting apparatus that sorts a plurality of coins having different diameters for each type and detects the number of sorted coins.
Specifically, the present invention relates to a coin sorting device and a coin sorting and counting device that can sort and count coins having different diameters at high speed.
Furthermore, the present invention relates to a coin sorting device and a coin sorting and counting device capable of sorting and counting high-speed and small coins having different diameters for each type.
In this specification, “coin” is a general term for coins as currency, medals of game machines, tokens, and the like.

As a first conventional technique, a coin is placed on the upper surface and rotated manually or by drive means, and has a coin intake from the outer periphery of the rotatable disk, and is provided along the outer periphery of the rotatable disk. Are arranged in a substantially arc-shaped coins transportation path and coins transportation path, and can be sorted and dropped from small diameter coins to large diameter coins in order from upstream to downstream A plurality of sorting holes, and a circle in a plan view that is arranged above the outer periphery of the rotating disk, rotates in synchronization with the rotation of the rotating disk, and conveys coins while pressing the coins toward the coin conveying path surface Coin discrimination for determining the number and diameter of coins that are arranged in the coin transfer path between the annular transfer belt, the coin intake and the most upstream sorting hole in the transfer direction hand And a control unit for calculating a measurement result by the coin determination unit, and a display unit for displaying a counting result such as a quantity and a total quantity of each type of the passed coins. Is known (for example, see Patent Document 1).
As a second prior art, a coin on a rotating disk is given a centrifugal force by the rotation of the rotating disk, and the coin is fed to the outlet of each denomination formed on the stationary peripheral surface by the centrifugal force and sorted by denomination. Is known (for example, see Patent Document 2).

Patent No. 3863490 (Figures 1-9, pages 3-10) Japanese Patent No. 2636505 (Figure 2-16, pages 4-7)

In the first conventional technique, coins transported by the frictional force of the transport belt with reference to the inner peripheral edge of the arc-shaped coin transport path are matched to the diameters of the denominations and formed in the sorting holes formed in order from the smallest diameter to the largest diameter. It is selected for each denomination by dropping it.
Since this method follows the inner peripheral edge with the coin as a reference by the pressing force of the transport belt, if the speed of the transport belt is increased to improve the sorting ability, the centrifugal force overcomes and the coin moves away from the inner peripheral edge, and the predetermined There is a problem that it cannot be dropped into the sorting hole.
In other words, the first prior art has a limit in improving the sorting ability.
There is a similar problem when the first prior art is used in a coin sorting and counting apparatus.

In the second prior art, since the coin is guided to the outlet for each denomination by the centrifugal force of the coin, the coin guiding path connected to the outlet must be arranged in the circumferential direction of the rotating disk, and there is a limit to downsizing.
There is a similar problem when the second prior art is used in a coin sorting and counting apparatus.

A first object of the present invention is to provide a coin sorting device that can increase the number of sorted coins per unit time.
A second object of the present invention is to provide a coin sorting device that is small in size and can increase the number of sorted coins per unit time.
A third object of the present invention is to provide a coin sorting / counting apparatus capable of increasing the number of sorted coins per unit time.
A fourth object of the present invention is to provide a coin sorting / counting apparatus that is small in size and can increase the number of sorted coins per unit time.

In order to achieve this object, a coin sorting device according to the present invention is configured as follows.
In a coin sorter that sorts coins of different diameters by diameter, a flat base plate, a reference rim having a predetermined radius from the rotation axis, extending from the reference rim in the circumferential direction, and coins one by one A rotating body having a feed blade to be conveyed and rotating on the upper side of the base plate, an outer side of the reference peripheral edge of the base plate, an inner guide edge located slightly outside the reference peripheral edge, and a radial direction from the reference peripheral edge A plurality of sorting holes having outer reference edges formed at intervals slightly smaller than the diameter of coins corresponding to the order of small coins to large coins, and smaller than the target coins downstream; A carp that is transported by the feed blades with a predetermined force toward the reference peripheral edge at a position beyond the outer reference edge of the hole. Pushing device, for biasing the a coin sorting apparatus characterized by having a.

  According to a second aspect of the present invention, there is provided the coin sorting device according to the first aspect, further comprising a drop assist device that presses a coin sent by a feed blade from the upper side of the sorting hole toward the sorting hole.

  According to a third aspect of the present invention, in the coin sorting device according to the first aspect, the pressing device is translated with respect to the reference peripheral edge by a parallel movement mechanism.

  According to a fourth aspect of the present invention, there is provided a coin sorting apparatus that sorts a plurality of types of coins having different diameters according to diameter, and has a flat base plate, a reference peripheral edge having a predetermined radius from the rotation axis, and extends in a circumferential direction from the reference peripheral edge. A rotating blade that rotates on the upper side of the base plate, an inner guide edge that is located slightly on the outer periphery of the reference peripheral edge, and A plurality of sorting holes having outer reference edges that are formed such that the radial distance from the reference peripheral edge is slightly larger than the diameter of coins corresponding to the order of small-diameter coins to large-diameter coins, and is smaller than the downstream target coins. The feed blades with a predetermined force toward the reference peripheral edge beyond the outer reference edge of the sorting hole on the base plate. Pushing device for biasing the coins to be conveyed Te, a coin sorting counting device being characterized in that a sensor is provided for detecting a fall to the sorting hole.

  According to a fifth aspect of the present invention, in the coin sorting device according to the second aspect, the drop assisting device is a roller that is disposed above the sorting hole and elastically pushes down the coin toward the sorting hole. .

  A sixth aspect of the present invention is the coin sorting device according to the fifth aspect, wherein a plurality of the rollers are provided.

In the invention of claim 1, the coins are slid on the base plate one by one by the feeding blades of the rotating body.
The sliding coin moves while being pressed with a predetermined force against the reference peripheral edge of the rotating body against the centrifugal force by the pressing device.
In the sorting hole, the inner edge of the coin is slid on the inner guide edge. Further, the outer edge of the coin slides on the outer reference edge in the selection hole of the coin having a smaller diameter than the corresponding denomination. When facing the sorting hole of the corresponding denomination, the pressing device does not come closer to the reference peripheral edge side than the outer reference edge of the sorting hole, so that the force pressing the coin against the reference peripheral edge is rapidly reduced. As a result, the outer edge of the corresponding coin that slides on the inner edge cannot be supported by the outer reference edge on the lower surface, so that it falls into the sorting hole by its own weight and / or urging force from above.
In the present invention, since the coin is pressed against the reference peripheral edge of the rotating body by the pressing device and dropped downward, the size can be reduced.
In addition, even if the rotational speed of the rotating body is increased, it is pressed against the reference periphery by the pressing device, so that the coin peripheral surface does not leave the reference periphery and can be reliably dropped into the corresponding denomination selection hole, so that high-speed selection is possible. Is possible.

In the invention of claim 2, the coin fed by the feed blade is pressed toward the sorting hole by the drop assist device.
Even if the moving speed of the coin increases and it cannot be dropped into the sorting hole by gravity alone, it can be surely dropped into the sorting hole, and even if the speed is increased, it can be surely dropped into the small sorting hole.
Therefore, even if it is small, coins can be sorted at high speed.

According to a third aspect of the present invention, the pressing device translates with respect to the reference peripheral edge by the translation mechanism.
As a result, the force for pressing the coin against the reference peripheral edge can be made substantially uniform as compared with the method of pressing with a lever rotating around the fulcrum, and the coin can be reliably pressed against the reference peripheral edge with a smaller force.
Further, even if the coin tries to push back the pressing device, the urging force is applied from the opposite direction to the pressing direction of the coin, so that the coin can be pressed against the reference peripheral edge with a small force, and the coin does not fall accidentally.
Further, the problem that the coin does not fall into the sorting hole due to the holding force by the pressing device can be solved.

In the invention of claim 4, the coins are slid on the base plate one by one by the feeding blades of the rotating body.
The sliding coin moves while being pressed with a predetermined force against the reference peripheral edge of the rotating body against the centrifugal force by the pressing device.
In the sorting hole, the inner edge of the coin is slid on the inner guide edge.
Further, the outer edge of the coin slides on the outer reference edge in the selection hole of the coin having a smaller diameter than the corresponding denomination. When facing the sorting hole of the corresponding denomination, the pressing device does not come closer to the reference peripheral edge side than the outer reference edge of the sorting hole, so that the force pressing the coin against the reference peripheral edge is rapidly reduced.
As a result, the outer edge of the corresponding coin that slides on the inner edge cannot be supported by the outer reference edge on the lower surface, so that it falls into the sorting hole by its own weight and / or urging force from above.
In the present invention, since the coin is pressed against the reference peripheral edge of the rotating body by the pressing device and dropped downward, the size can be reduced.
Further, even if the rotational speed of the rotating body is increased, the pressing device presses against the reference periphery, so that the coin peripheral surface does not leave the reference periphery and can be reliably dropped into the corresponding denomination sorting hole.
Furthermore, since it has the sensor of the coin which fell, since the number of selection coins according to the denomination can be counted, it is possible to realize a small coin selection and counting device with high selection capability.

In the invention of claim 5, the coin rotated by the rotating body is elastically pushed down toward the sorting hole by a roller disposed on the upper side in the sorting hole.
Therefore, the coin to be dropped is forcibly dropped into the sorting hole by this push-down force and sorted into an appropriate sorting hole.
Since it is a roller that pushes down the coin, the frictional force with the coin is extremely small. In other words, the rotational resistance of the rotating body is small.
Therefore, even if the moving speed of the coin is high, it can be quickly dropped into a predetermined sorting hole, so that there is an advantage that sorting can be performed reliably even if the speed is increased.

In the invention of claim 6, the coin moved by the rotating body is elastically pushed down toward the sorting hole by a plurality of rollers arranged on the upper side in the sorting hole.
When the coin is pushed down by the plurality of rollers, the coin is pushed down by the surface, so that the coin is moved downward in parallel.
This has the advantage that coins can be dropped into the sorting hole more smoothly than a single roller, and further high-speed sorting can be performed.

  The best mode of the present invention is a coin sorting apparatus that sorts coins of different diameters according to diameter, and has a flat base plate, a reference periphery having a predetermined radius from the rotation axis, and from the reference periphery in the circumferential direction. A rotating body that extends and conveys coins one by one, and rotates on the upper side of the base plate; on the outer side of the reference peripheral edge of the base plate; A plurality of selections having outer reference edges formed such that the radial distance from the reference peripheral edge is slightly larger than the diameter of coins corresponding to the order of small-diameter coins to large-diameter coins and smaller than the target coins downstream. The feed blade with a predetermined force toward the reference peripheral edge at a position beyond the outer reference edge of the sorting hole on the base plate Therefore, a pressing device that biases the coins to be conveyed, and a drop assist device that presses the coins that are fed from the upper side of the sorting hole toward the sorting hole by a feeding blade, and the pressing device is configured to move the reference peripheral edge by a parallel movement mechanism. It is a coin sorter characterized by being moved in parallel.

A coin sorting and counting apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS.
The coin sorting / counting device 100 roughly includes a coin sorting device 102 and a coin counting device 104.
The coin sorting and counting apparatus 100 has a function of sorting a plurality of denomination coins having different diameters for each denomination and counting coins for each sorting denomination.

First, the coin sorting device 102 will be described with reference to FIGS.
The coin sorting device 102 has a function of sorting coins into denominations.
The coin sorting device 102 includes a base 106, a coin aligning device 108, and a coin sorting device 112.

The base 106 is described with reference to FIGS.
The base 106 has a function of supporting the coin alignment device 108, the coin sorting device 112, and the like.
The base 106 includes a left side frame 114 having a trapezoidal shape in a side view, a right side frame 116, and stays 118 and 122 connecting the both.
A base plate 124 is inclined and fixed to the upper ends of the base left side frame 114 and the right side frame 116.
A coin aligning device 108, a coin sorting device 112, and the like are attached to the base plate 124.

Next, the coin alignment device 108 will be described with reference to FIGS.
The coin aligning device 108 has a function of sorting and sending out a plurality of types of loose coins having different diameters one by one.
The coin aligning device 108 is not limited to the embodiment, and other similar devices can be used.
The coin aligning device 108 of this embodiment includes a base plate 124, a rotating disk 126, and a storage bowl 128.

First, the base plate 124 will be described.
The base plate 124 has a function of supporting the lower surface of the coin that is dropped into the through hole 132 of the rotating disk 126 and pushed by the rotating disk 126.
The base plate 124 has a rectangular flat plate shape, and since the coin slides, the base plate 124 is preferably made of a metal such as stainless steel so as not to be worn.

Next, the rotating disk 126 will be described.
The rotating disk 126 has a function of stirring coins held in a loose state in the holding bowl 128, sorting them one by one, and sending them out one by one.
The rotating disk 126 has a disk shape, and a plurality of circular through holes 132 are formed on the periphery of the coins to drop coins at equal intervals.
The through-hole 132 is a circular hole having a diameter slightly larger than the maximum diameter coin to be selected.
The rear peripheral surface 134 at the rear side in the rotation direction on the upper surface side of the through-hole 132 is formed obliquely and formed in a mortar shape.
Coin pushing ridges 138 and 142 are formed on the lower surface of the rib 136 between the through holes 132 of the rotating disk 126.

The rotating disk 126 is concentrically disposed in a guide hole 146 of a guide ring 144 that surrounds approximately three quarters of a thin plate slightly thicker than the maximum coin thickness fixed to the upper surface of the base plate 124.
The rotating disk 126 is selectively forwardly or reversely rotated through a speed reducer 152 by an electric motor 148 disposed in an inverted state on the side.
In the present embodiment, forward rotation is clockwise rotation in FIG. 3, and reverse rotation is counterclockwise rotation.
A frustoconical stirring body 154 is formed at the center of the rotating disk 126.

Next, the holding bowl 128 will be described.
The holding bowl 128 has a function of holding a large number of coins in a loose state.
The storage bowl 128 is a vertical cylindrical body, the lower end 156 is formed in a circle slightly larger than the rotating disk 126, the upper end 158 is formed in a rectangular shape in plan view, and the lower end and the upper end are connected by a slope 162. ing.
The retaining bowl 128 is detachably fixed to the upper surface of the base plate 124 by hooking a latching hook (not shown) at the lower end to the latching hole 160 of the base plate 124 and fixing the opposite side with the fixing device 161. The
The rotating disk 126 is disposed at the bottom of the lower end 156 of the storage bowl 128.

Various coins stacked in the holding bowl 128 are agitated by the rotation of the rotating disk 126.
More specifically, the coin on the rotating disk 126 falls into the through hole 132, rides on the rib 136, and is stirred by the top slope of the stirring member 154.
When the coin C falls into the through hole 132 in parallel with the pace plate 124 by this stirring, the lower surface of the coin C is supported on the upper surface of the base plate 124.
In other words, the coins C are classified one by one.
Further, since the peripheral edge of the coin is pushed by the pushing ridges 138 and 140, the coin C is rotated by the rotating disk 126 while being guided by the inner peripheral surface of the guide hole 146 of the guide ring 144.
The coin C to be rotated is guided in the circumferential direction by the restriction pins 160 and 161 that elastically protrude upward from the base plate 124 at the sending-out portion 159, and is sent out one by one.
The pace plate 124 can be arranged horizontally, but when tilted, there are advantages that the coin load on the rotating disk 126 can be reduced and the lower space can be used effectively.

Next, the coin sorting device 112 will be described with reference to FIGS.
The coin sorting device 112 has a function of sorting coins by denomination, more specifically, a function of mechanically sorting coins by diameter using a difference in coin diameter.
The coin sorter 112 includes a rotating body 164, a first sorting hole 166, a second sorting hole 168, a third sorting hole 172, a fourth sorting hole 174, and a first pressing device 176 provided corresponding to each sorting hole, A second pressing device 178, a third pressing device 180, and an upper surface regulating body 182 are included.

First, the rotating body 164 will be described.
The rotating body 164 has a function of receiving the coins C sent out one by one by the coin aligning device 108 and sequentially transporting them from the first sorting hole 166 to the fourth sorting hole 174.
The rotator 164 has a disc shape, and has the same number as the arc-shaped reference peripheral edge 184 formed at a predetermined radius from the rotation axis 183 and the through holes 132 of the rotary disk 126 protruding in the radial direction from the reference peripheral edge 184. , Feed blades 186 provided at equal intervals.
The holding recess 188 between the feeding blades 186 is formed to a size that does not hold one maximum diameter coin and two minimum diameter coins.

The rotating body 164 is rotated from a driving source of the rotating disk 126 via gear means (not shown) in a plane having a distance equal to or less than the thickness of the thinnest coin C with respect to the upper surface of the base plate 124, and is counterclockwise in FIG. The direction of rotation is synchronized with the rotating disk 126.
Since the reference peripheral edge 184 is located on the same radius, it moves on the same circle even if the rotating body 164 rotates.
The feed blades 186 are formed to have the same radius, and the tip is set so as to pass below the rotary disk 126.
As a result, the coin C sent out in the circumferential direction by the restriction pins 160 and 161 by the rotation of the rotary disk 126 is received by the feed blade 186 and then conveyed through the sorting passage 190 while being pushed by the feed blade 186.

The first sorting hole 166, the second sorting hole 168, and the third sorting hole 172 will be described.
The first sorting hole 166, the second sorting hole 168, and the third sorting hole 172 have a function of dropping a coin C having a predetermined diameter.
Since the first sorting hole 166, the second sorting hole 168, and the third sorting hole 172 have the same basic structure, the first sorting hole 166 will be described as a representative.

As shown in FIG. 6, the first selection hole 166 is an arc-shaped long hole formed by an arc-shaped inner edge 192 that is an inner guide edge and an arc-shaped outer edge 194 that is an outer reference edge formed in the base plate 124.
The arc-shaped inner edge 192 has a predetermined radius that is slightly larger than the reference peripheral edge 184 around the rotation axis 183 of the rotating body 164.
In other words, an arc-shaped inner coin guide 195 is formed between the reference peripheral edge 184 and the arc-shaped inner edge 192.
The arcuate inner edge 192 is preferably about 1 mm or more larger than the reference peripheral edge 184.
This is because the coin C to be sorted (dropped) easily falls. However, if the difference in radius is too small, there is a risk of misselection, and if it is too large, the coin C will not easily fall, so about 1 to 3 mm is preferable.
In other words, the width of the inner coin guide 195 is preferably about 1 mm or more.
Further, in order to reduce the resistance to the falling coin C, the arc-shaped inner edge 192 is preferably chamfered and then buffed and formed smoothly.
The arc-shaped outer edge 194 may be formed on the base plate 124, but in this embodiment, it is constituted by a slide plate 198 fixed to the base plate 124.

A rectangular slide hole 200 is formed in the base plate 124 radially outward of the arc-shaped outer edge 192, and the slide plate 198 is fitted so as to be slidable in the radial direction of the reference peripheral edge 184.
In other words, the slide plate 198 can be translated by the right edge 202 and the left edge 204 of the slide hole 200 while keeping the arcuate outer edge 194 concentric with the reference peripheral edge 184.
The right edge 202 and the left edge 204 are slide plates 198, specifically guide devices 206 for the arcuate outer edge 194.
The guide device 206 can be changed to a device having the same function in place of the present embodiment.

Next, the fixing device 208 for the slide plate 198 will be described with reference to FIGS.
The fixing device 208 has a function of fixing the slide plate 198 to the base plate 124 at an appropriate position, and includes a support plate 212 and bolts 214.
The support plate 21 2 has a rectangular shape, and long holes 216 (four in the embodiment) that extend in the radial direction with respect to the reference peripheral edge 184 are formed in the side edges protruding from the slide plate 198.
The inner edge 213 facing the reference peripheral edge 184 of the support plate 21 2 is formed with the same curvature as the arc-shaped outer edge 194.
The support plate 21 2 and the slide plate 198 are integrated by a knock pin (not shown) so that the inner edge 213 is located slightly outside the arcuate outer edge 194 with respect to the reference peripheral edge 184, and can be moved together.

The support plate 212 is fixed by screwing into the base plate 124 a bolt 214 that is applied from below the base plate 124 and penetrates the long hole 216.
In other words, the distance between the arcuate outer edge 194 and the reference peripheral edge 184 is set by the fixing position of the support plate 212 with respect to the base plate 124.
The distance between the arc-shaped outer edge 194 and the reference peripheral edge 184 is adjusted according to the diameter of the coin C to be selected.
For example, when selecting 50 yen coins, the 50 yen diameter is 21 mm, but the next smallest 100 yen coin with a diameter of 22.6 mm is set not to fall.
In other words, the distance between the reference peripheral edge 184 and the arcuate outer edge 194 is set in a range exceeding 21 mm and less than 22.6 mm.

  In addition, since the arc-shaped outer edge 194 is uniquely formed at a predetermined radius centered on the rotation axis 183, it is not positioned on the same radius centered on the rotation axis 183. It is determined so as to satisfy the position at the maximum distance from the outer edge 194.

Next, the coin guide plate 218 will be described with reference to FIG.
The coin guide plate 218 has a function of causing the coin C dropped from the first sorting hole 166 to collide and the inertial force due to the centrifugal force to be attenuated, and to drop by gravity in the drooping direction.
The coin guide plate 218 is an arc-shaped plate having a predetermined width, and is fixed to the lower surface adjacent to the inner edge 213 of the support plate 212.
The coin C having centrifugal force that has dropped from the first sorting hole 166 collides with the coin guide plate 218 so that the inertial force in the radial direction is extinguished, and falls downward while slightly rebounding.
As a result, the coin can be dropped almost directly below, which can also reduce the size.

Next, the fourth selection hole 174 will be described.
In the fourth sorting hole 174, the largest 500 yen coin falls.
Therefore, the adjustment mechanism is not necessary as long as the 500-yen coin is dropped.
In this embodiment, the opening is rectangular.

In this embodiment, 10 yen, 50 yen, 100 yen, and 500 yen coins are to be sorted, so the first sorting hole 166, the second sorting hole 168, and the third sorting are arranged at almost equal intervals from the small diameter to the large diameter. A hole 172 and a fourth sorting hole 174 are arranged.
In other words, each reference is such that the smallest 50 yen coin falls in the first sorting hole 166, the second smallest 100 yen coin falls in the second sorting hole 168, and the third smallest 100 yen coin falls in the third sorting hole 172. A distance between the peripheral edge 184 and the arcuate outer edge 194 is set.
The maximum 500 yen coin is set to fall into the fourth sorting hole 174.
The fourth sorting hole 174 is formed larger than the diameter of 500 yen, and is set so that coins exceeding the diameter of 500 yen coins fall.
The coins C that have fallen from the first sorting hole 166, the second sorting hole 168, the third sorting hole 172, and the fourth sorting hole 174 are guided by individual passages and are retained in the collection bags for each denomination.

Next, the first pressing device 176, the second pressing device 178, and the third pressing device 180 will be described with reference to FIGS.
Each pressing device 176, 178, 180 has a function of pressing the coin C, which is slid on the base plate 124 by the feed blade 186, with a predetermined force toward the reference peripheral edge 184 beyond the arcuate outer edge 194 of the corresponding selection hole.
The pressing device can be changed to another device having a similar function.
Since the first pressing device 176, the second pressing device 178, and the third pressing device 180 have the same configuration, the first pressing device 176 will be described as a representative.

The first pressing device 176 includes a pressing body 222, a pressing body guide device 224, and an urging means 226.
First, the pressing body 222 will be described.
The pressing body 222 has a generally trapezoidal flat plate shape, and a long edge is formed with a pressing edge 228 for pressing the coin C toward the reference peripheral edge 184.
The pushing edge 228 is formed to have the same curvature as the arcuate outer edge 198, and an upstream end with respect to the rotation direction of the rotating body 164 is formed with a guide edge 232 extending in the direction away from the reference peripheral edge 184 toward the upstream. ing.
The pressing body 222 can slide on the upper surface of the slide plate 198.

Next, the pressing body guide device 224 will be described.
The pressing body guide device 224 has a function of guiding the pressing body 222 so as to move in parallel with respect to the reference peripheral edge 184. In this embodiment, the pressing body guide device 224 is a six-bar parallel mechanism based on a four-bar parallel link mechanism that is a parallel movement mechanism. The link mechanism 228 is used.
This is because, by moving the pressing body 222 in parallel, the collision angle between the coin C moved by the feed blade 186 and the guide edge 232 can be reduced, and the coin C can be prevented from rampage (irregular movement).
The parallel link mechanism 228 has a pair of first support shaft 232F and second support shaft 232S protruding downward in parallel from the back surface of the support plate 212, and one end thereof is supported by the first support shaft 232F or the second support shaft 232S. The first link 234F, the second link 234S, the third link 238F in which the end support shaft 236F is pivotally supported by the bearing at the end of the first link 234F, and the support shaft 236S at the other end of the second link 234S A fourth link 238S that is pivotally supported by the bearings of the first portion, a third link 238F, a bearing 242F that is pivotally supported by the bearings 242F and 242S at the other end of the fourth link 238S, Consists of 244S.

The first link 234F and the second link 234S have the same length, and the third link 238F and the fourth link 238S have the same length.
The support shafts 244F and 244S pass through long holes 246F and 246S formed so as to overlap the slide plate 198 and the support plate 212.
Therefore, the pressing body guide device 224 is disposed on the back side of the base plate 124.
When the pressing body 222 slides on the slide plate 198, the third link 238F, the fourth link 238S, the first link 234F, and the second link 234S rotate equiangularly around the support shaft via the support shafts 244F and 244S, respectively. So move in parallel.

In order to stabilize the moving posture of the pressing body 222, it is preferable to provide the second pressing body guide device 248.
The second pressing body guide device 248 of the embodiment includes a cylindrical guide 252 protruding upward from the upper surface of the slide plate 198 and a rectangular guide hole 254 formed at the center of the pressing body 222.
This is to allow the inner surface of the guide hole 254 to move while being in sliding contact with the outer periphery of the guide 252, thereby restricting the movement of the pressing body 222 in the lateral direction and smoothing the movement of the pressing body 222. .

Next, the biasing means 226 will be described with reference to FIG.
The urging means 228 has a function of urging the pressing body 222 toward the reference peripheral edge 184 with a predetermined force.
The biasing means 228 is a spring 256 that is one of elastic bodies in the embodiment.
One end of the spring 256 protrudes from a latch pin 258 protruding from the lower surface of the support plate 212, and the other end protrudes downward from the lower surface of the pressing body 222 and protrudes from a long hole 262 formed so as to overlap the support plate 212 and the slide plate 198. The pressing body 222 is set to be urged to the reference peripheral edge 184 with a predetermined force by being hooked on the latch pin 264.
The pushing edge 228 of the pressing body 222 is positioned so as to be flush with the arcuate outer edge 194 when the outer edge 260 of the guide hole 254 contacts the outer periphery of the guide 252.
It is preferable to apply a urethane sheet to the outer edge 260 to mitigate the collision impact of the pressing body 222 and prevent bounce.

Next, the upper surface restricting body 182 will be described.
The upper surface regulating body 182 has a function of defining the upper surface of the sorting passage 190.
The upper surface restricting body 182 is disposed in parallel to the base plate 124 at an interval exceeding the maximum coin thickness and not more than two of the thinnest coin thickness.
This is because two coins C pushed by the feed blade 186 do not overlap.
However, it is preferable to set it slightly larger than the thickness of the thickest coin.
This is to stabilize the posture of the coin C to be transferred.
In this case, when the coin C falls into the corresponding sorting hole, the coin C falls so as to rotate around the arcuate inner edge 192, so that the inner edge of the coin C comes into pressure contact with the upper surface regulating body 182 and the coin C falls smoothly. May not.
Therefore, it is preferable to form a relief groove 265 as shown in FIG. 9 in a predetermined range facing the sorting passage 190 of the upper surface regulating body 182 and adjacent to the reference peripheral edge 184.
Since the inner edge of the coin C to be dropped enters the escape groove 265, the drop resistance is reduced, so that the coin C is smoothly dropped.
In this embodiment, the escape groove 265 is formed in a ring shape for convenience of manufacturing, but it may be formed at least at a position corresponding to the selection hole.

Next, the first drop assist device 266, the second drop assist device 268, and the third drop assist device 272 will be described with reference to FIGS.
The drop assist devices 266, 268, and 272 are provided corresponding to the first sorting hole 166, the second sorting hole 168, and the third sorting hole 172, and the coin C corresponding to each sorting hole is surely dropped. Has the function to push C down.
Since the first drop assist device 266, the second drop assist device 268, and the third drop assist device 272 have the same configuration, the first drop assist device 266 will be described as a representative.

The first drop assist device 266 includes a holding body 274, a pressing roller 276, and an urging means 278.
The holding body 274 is fixed to the upper surface of the upper surface regulating body 182, and a support shaft 282 is supported so as to be movable in a long hole 284 extending in a direction orthogonal to the upper surface regulating body 182 formed on the left and right side walls.
A pressing roller 276 is rotatably mounted on the support shaft 282, and a lower end circumferential surface thereof is positioned in the sorting passage 190 through a rectangular opening 286 formed in the upper surface regulating body 182.
A support shaft 286 is attached to the holding body 274 in parallel with the support shaft 282, and a spring 288 is wound around, and its free ends are locked to both ends of the support shaft 282, and a biasing force toward the base plate 124 is applied to the support shaft 282. is doing.
In other words, the coin C moving in the sorting passage 190 is pressed against the base plate 124 by the pressing roller 276, and the 50 yen coin C is pushed down into the first sorting hole 166 and dropped.

When a coin C that is not selected passes through the first sorting hole 166, for example, when a 100-yen coin passes through the first sorting hole 166, the diameter of the 100-yen coin is larger than the 50-yen coin. It is pressed against the reference peripheral edge 184 by 222.
The pressing body 222 is pressed by the 100-yen coin C, translated by the translation mechanism 228, and separated from the reference peripheral edge 184.
Thus, an arc-shaped outer coin guide 290 is formed between the pushing edge 228 of the pressing body 222 and the arc-shaped outer edge 194.
Therefore, the 100-yen coin C is supported by the inner coin guide 195 on the inner lower surface and the outer coin guide 290 on the outer lower surface. Therefore, even if the 100 yen coin C is pressed by the pressing roller 276 of the first drop assist device 266, Pass without falling.
At this time, since the pressing roller 276 is pushed up by these coins C, the support shaft 282 is moved in the direction away from the base plate 124 along the long holes 284, thereby allowing the coins C to pass.
Similarly, 10-yen and 500-yen coins C move without falling while being pressed against the inner coin guide 195 and the outer coin guide 290.

Next, the coin counting device 104 will be described with reference to FIG.
The coin counting device 104 has a function of counting the number of coins C received for each denomination.
Therefore, it is not limited to an Example, It can change into the other mechanism which has the same function.
The coin counting device 104 according to the embodiment faces the sorting passage 190 and is disposed between the first sensor 292 disposed immediately before the first sorting hole 166 and between the first sorting hole 166 and the second sorting hole 168. 2 sensor 294, third sensor 296 disposed between second sorting hole 168 and third sorting hole 172, fourth sensor 298 disposed between third sorting hole 172 and fourth sorting hole 156, fourth A fifth sensor 300 and a microprocessor 302 provided in the sorting hole 174 are included.

In the embodiment, the first to fifth sensors are reflective sensors that detect the reflected light from the coin C and detect the passage of the coin C.
However, a transmissive sensor, a mechanical sensor, or the like can be used.

The first sensor 292, the second sensor 294, the third sensor 296, the fourth sensor 298, and the fifth sensor 300 output detection signals to the microprocessor 302.
The microprocessor 302 processes the detection signal from each sensor based on a program stored in a ROM (not shown), confirms whether a coin of a predetermined denomination has dropped into a predetermined sorting hole, and selects a selected coin. Has the function of counting numbers.

Specifically, if the detection signal is not output from the second sensor 294 within a predetermined time from the detection signal of the first sensor 292, it is determined that 50 yen coins have fallen into the first sorting hole 166 and Count 1
When a detection signal is not output from the third sensor 296 within a predetermined time after a detection signal is output from the second sensor 294 within a predetermined time from the first sensor 292, a 100 yen coin has dropped into the second sorting hole 168. Judge 1 thing for 100 yen coins.
A detection signal is output from the second sensor 294 within a predetermined time from the first sensor 292, a detection signal is output from the third sensor 296 within a predetermined time, and a detection signal is output from the fourth sensor 298 within a predetermined time. Is not output, one 10-yen coin is counted as 10-yen coins falling into the third sorting hole 172.

A detection signal is output from the second sensor 294 within a predetermined time from the first sensor 292, a detection signal is output from the third sensor 296 within a predetermined time, and a detection signal is output from the fourth sensor 298 within a predetermined time. Is output and a detection signal is output from the fifth sensor 300, one 500-yen coin is counted as a 500-yen coin selected.
The predetermined time may be replaced by attaching an encoder to the rotating disk 126 or the rotating body 164 and determining that the number of pulse signals output from the encoder has reached a predetermined number.

Next, the movement guide device 304 will be described with reference to FIGS.
The movement guide device 304 has a function of smoothly guiding the coins C having different diameters to the first pressing body 222.
The movement guide device 304 rotates the roller 306 disposed on the side of the sorting passage 190 between the rotary disk 126 and the first pressing body 222, the lever 308 that supports the roller 306, and the lever 308 in FIG. Includes spring 312 to let you.

The lever 308 is attached to a support shaft 314 protruding from the back surface of the base plate 124 so as to be rotatable in the middle.
It is fixed to one end of the lever 308 and is rotatably attached to the tip of a support shaft 318 that passes through the long hole 316 of the base plate 124.
One end of the spring 312 is hooked to a hooking body (not shown) protruding from the base plate 124, and the other end is hooked to a hooking hole (not shown) of the lever 308. In FIGS. Giving to Leva 308.
The roller 306 is disposed at a position where it comes into contact with the coin C when a coin other than the smallest 50 yen coin passes.
However, the roller 306 may be disposed so as to contact all coins of 50 yen to 500 yen.
This is to prevent the coin C from being exposed by being pressed against the reference peripheral edge 184 by the roller 306 before being pressed against the reference peripheral edge 184 by the pressing body 222.

Next, the operation of this embodiment will be described.
Place 10 to 500 yen coins C into the holding bowl 128 in a stacked state.
As the rotating disk 126 rotates, the coins C are agitated and fall into the through hole 132, guided by the regulation pins 160 and 161, and sent one by one in the circumferential direction of the rotating disk 126.
The coin C sent out to the rotation path of the feed blade 186 is received by the feed blade 186, slides on the base plate 124, and is transferred through the circular sorting passage 190.

First, a case where 50 yen coins are sent to the sorting passage 190 will be described.
The 50-yen coin is guided by the roller 306 by the rotation of the rotating body 164, or reaches the guide edge 232 of the pressing body 222 without being guided, and is guided to the reference peripheral edge 184 side by the guide edge 232, and subsequently pushed. It is guided by the edge 228 to the reference peripheral edge 184 side.
Since the distance between the reference peripheral edge 184 and the pushing edge 228 is slightly larger than the diameter of the 50 yen coin, the 50 yen coin is transported through the sorting passage 190 by the feed blade 186 in contact with the pushing edge 228 by centrifugal force. The
In the first selection hole 166, the lower surface on the reference peripheral edge 184 side of the 50-yen coin C is supported by the inner coin guide 195, but the lower surface on the arcuate outer edge 198 side is not supported by the outer coin guide 290.
Further, the pressing roller 276 is pressed down with a predetermined force.
Thereby, the 50-yen coin C is pushed down by the roller 276 and falls into the first sorting hole 166 (see FIG. 11).
On the other hand, the 50-yen coin C is detected by the first sensor 292 before reaching the first sorting hole 166.
However, since the second sensor 294 does not detect within a predetermined time, the microprocessor 302 counts 50 yen as 1.

Next, a case where 100 yen coin C is sent out will be described.
First, the 100-yen coin C collides with the roller 306, moves to the reference peripheral edge 184 side, and is pressed against the reference peripheral edge 184.
Next, the first sorting hole 166 is reached, but since the diameter is larger than the 50-yen coin, the pressing body 222 is pushed away from the reference peripheral edge 184.
As a result, the upper surface of the slide plate 198 appears between a position farther from the reference peripheral edge 184 than the arc-shaped outer edge 198 of the slide plate 198 and the pushing edge 228. It passes through the first selection hole 166 while being pushed by the first drop assist device 266 while being supported by the coin guide 290 (see FIG. 6).
Next, the 100 yen coin C reaches the second sorting hole 168.
Since the second sorting hole 168 is a hole through which the 100-yen coin C is dropped, it is dropped into the second sorting hole 168 in the same manner as the 50-yen coin.
On the other hand, after the second sensor 294 outputs the detection signal within a predetermined time after the coin detection by the first sensor 292, the detection signal of the third sensor 296 is not output within the predetermined time. Count as 1.

Next, a case where a 10 yen coin C is sent out will be described.
First, the 10-yen coin C collides with the roller 306, moves to the reference peripheral edge 184 side, and is pressed against the reference peripheral edge 184.
Next, the first sorting hole 166 is reached, but since the diameter is larger than the 50-yen coin, the pressing body 222 is pushed away from the reference peripheral edge 184.
Thus, the 100 yen coin C passes through the first sorting hole 166 while being pressed by the pressing device 176 while being supported by the inner coin guide 195 and the outer coin guide 290 on the lower surface.
Next, the 10-yen coin C reaches the second sorting hole 168.
Since the 10-yen coin C is larger than the 100-yen coin, it similarly passes through the second sorting hole 168.
Next, the 10 yen coin C reaches the third sorting hole 172.
Since the third sorting hole 172 is a hole through which the 10-yen coin C is dropped, it is dropped into the third sorting hole 172 as in the case of the 50-yen coin.
On the other hand, after the second sensor 294 outputs the detection signal within a predetermined time after coin detection by the first sensor 292, the third sensor 296 outputs the detection signal within the predetermined time, and the fourth sensor 298 outputs the predetermined time. Since the detection signal is not output, the microprocessor 302 counts 10 yen as 1.

Next, a case where a 500 yen coin C is sent out will be described.
The 500-yen coin C first collides with the roller 306 and is moved to the reference peripheral edge 184 side, and is pressed against the reference peripheral edge 184.
Next, the first sorting hole 166 is reached, but since the diameter is larger than the 50-yen coin, the pressing body 222 is pushed away from the reference peripheral edge 184.
Thus, the 100 yen coin C passes through the first sorting hole 166 while being pressed by the pressing device 176 while being supported by the inner coin guide 195 and the outer coin guide 290 on the lower surface.
Next, the 500 yen coin C reaches the second sorting hole 168.
Since the 500 yen coin C is larger than the 100 yen coin, it similarly passes through the second sorting hole 168.
Next, the 500 yen coin C reaches the third sorting hole 172.
Since the 500 yen coin C is larger than the 100 yen coin, it similarly passes through the third sorting hole 172.
Next, the 500 yen coin C reaches the third sorting hole 172.
Since the third sorting hole 172 is larger than the 500 yen coin C, the 500 yen coin C falls into the third sorting hole 172.
On the other hand, after the second sensor 294 outputs a detection signal within a predetermined time after coin detection by the first sensor 292, the third sensor 296 outputs a detection signal within the predetermined time, and the fourth sensor 298 within the predetermined time. Since the fifth sensor 301 further outputs a detection signal after outputting the detection signal, the microprocessor 302 counts 500 yen as 1.

When this sorting and counting operation is continuously performed, all the coins C in the holding bowl 128 are counted, and when the first sensor 292 does not output a detection signal for a predetermined time or more, it is assumed that all the coins C have been counted. Is stopped.
Note that when the count value of coins reaches a predetermined value, for example, 1000, the coin may be stopped.

Next, different embodiments of the drop assist device will be described with reference to FIGS.
The drop assist devices 320A to 320D of the present embodiment have the same basic concept of pushing down the coin C by the elastically biased roller 322 as in the previous embodiment, but there are a plurality of rollers 322, three in the embodiment. The difference is that it is composed of rollers.
The same parts as those in the previous embodiment are denoted by the same reference numerals, and different configurations will be described.
The drop assist devices 320A to 320D are respectively disposed above the first sorting hole 166, the second sorting hole 168, the third sorting hole 172, and the fourth sorting hole 174, respectively.
Since the drop assist devices 320A to 320D have the same configuration, the first drop assist device 320A shown in FIGS. 14 and 15 will be described as a representative.

The horizontal portion 324H of the L-shaped bracket 324 is fixed to the upper surface restricting body 182 to constitute a vertical portion 324V. The suspending means suspending with respect to the upper surface regulating body 182.
One end of a support shaft 326 extending laterally from the vertical portion 324V is fixed.
In other words, the support shaft 326 is arranged in parallel to the upper surface regulating body 182 in a cantilever state.
An upper end of an angle-shaped swing bracket 328 is swingably attached to the support shaft 326.
The lower end 332 of the swing bracket 328 is substantially suspended from the upper surface restricting body 182 and extends along the opening 286.
Specifically, the lower end portion 332 is formed by the central portion 332C, the upstream portion 332U, and the downstream portion 332D, and has an upstream portion with respect to the central portion 332C so as to have the same curvature as the circular path of the coin C transferred through the sorting passage 190. 332U and the downstream portion 332D are bent at an obtuse angle.

With respect to the movement of the coin C in the sorting passage 190, the upstream portion 332U, the central portion 332C, and the downstream portion 332D are arranged in this order.
A lateral upstream support shaft 334U, a center support shaft 334C, and a downstream support shaft 334D are fixed to the upstream portion 332U, the center portion 332C, and the downstream portion 332D, respectively, and the upstream roller 334U is connected to the upstream roller 322U and the center support shaft 334C is connected to the center roller. A downstream roller 322D is rotatably attached to 322C and the downstream support shaft 334D.
The lower ends of the upstream roller 322U, the central roller 322C, and the downstream roller 322D protrude into the sorting passage 190 from the opening 286 that faces each sorting hole.

The intervals between the rotation centers of the upstream roller 322U and the center roller 322C, and the center roller 322C and the downstream roller 322D are set to be the same, and the intervals between the rotation centers are arranged at an interval narrower than the diameter of the smallest coin C to be selected.
In other words, since the distance between the rotation axes of the upstream support shaft 334U and the central support shaft 334C or the central support shaft 334C and the downstream support shaft 334D is smaller than the diameter of the coin to be selected, at least two rollers are simultaneously relative to the upper surface of the coin. It is set so that a positional relationship is generated.

Further, since the upstream portion 332U and the downstream portion 332D are bent at an obtuse angle with respect to the central portion 332C, the upstream roller 322U, the central roller 322C, and the downstream roller 322D are arranged on an arc in accordance with these.
This arc is preferably set so as to roughly match the arc drawn by the center of the coin C moving in the sorting passage 190.
As a result, since the center of the coin C is pushed down, the coin C can be pushed down most effectively.

A spring 344 is locked between a fixed locking portion 338 protruding laterally from the horizontal portion 324H of the bracket 324 and a moving locking portion 342 protruding laterally from the swing bracket 328, and the swing bracket 328 is In FIG. 15B, it is biased clockwise.
A stopper 346 is fixed to the horizontal portion 324H.
In the state where the buffer body 348 made of an elastic body is fixed to the horizontal portion of the swing bracket 328 and the buffer body 348 is locked to the stopper 346, the upstream roller 322U, the center roller 322C, and the downstream roller 322D are placed in the sorting passage 190. It is set to stand vertically.
At this time, the intervals between the lower ends of the upstream roller 322U, the central roller 322C, and the downstream roller 322D and the upper surface of the base plate 124 are set smaller than the thickness of the coin.
In other words, the various coins C moving in the sorting passage 190 are pushed down by the upstream roller 322U, the central roller 322C, and the downstream roller 322D.

In this embodiment, the lower ends of the upstream roller 322U and the central roller 322C, and the central roller 322C and the downstream roller 322D come into contact with the upper surface of the coin C moving in the sorting passage 190 and are simultaneously pushed down.
In other words, since the coin C is simultaneously pushed down by the two rollers, it is pushed down in parallel.
Thereby, since the posture in which the coin C is pushed down is stabilized, the coin C can be smoothly dropped into the corresponding sorting hole.
Therefore, the speed of the feed blade 186, in other words. Even if the sorting speed is increased, there is an advantage that it can be surely dropped into the sorting hole of the corresponding diameter.
In this embodiment, the pitch of the upstream roller 322U and the central roller 322C, the central roller 322C and the downstream roller 322D is set corresponding to the diameter of the 50-yen coin that is the minimum diameter coin to be selected, and all four denominations have the same setting product. By using it, the cost can be reduced.

More preferably, the amount of protrusion to the sorting path 190 is increased in the order of the upstream roller 322U, the central roller 322C, and the downstream roller 322D with respect to the moving direction of the coin C.
In other words, the upstream support shaft 334U, the central support shaft 334C, and the downstream support shaft 334D are preferably arranged on a straight line that is inclined downward with respect to the moving direction of the coin C.
In the sorting hole to be dropped, the coin C is first pushed down by the upstream roller 322U and falls slightly in the city, and then is opposed to the central roller 322C, so if it is at the same position, it may not be pushed down by the central roller 322C. It is.
In order to obtain the same effect, the downstream roller 322D protrudes into the sorting path 190 rather than the central roller 322C.

  In the embodiment of FIGS. 12 to 15, the sensor of the coin C is such that the roller 350 is pushed up by the coin C moving in the sorting passage 190, and a part of the swing lever 352 to which the roller 350 is attached is photoelectrically operated. A mechanical sensor that detects the optical axis of the sensor 354 by blocking the optical axis is used.

The coin sorting / counting apparatus 100 of the present invention can be used, for example, as a sorting / counting machine for collecting coins from a safe provided for each game machine in a game field.
Because it is compact, it can be loaded onto a moving carriage and even a safe with mixed denominations can be sorted and counted for each denomination, so even if multiple denominations are mixed in the safe, it is put into the coin sorting and counting device 100 as it is it can.
