DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin handling machine such as a circulating coin depositing and dispensing machine for reusing coins stored in a depositing process for a dispensing process, and more particularly to a coin storing device using a rotating cylinder. Related to the device.

[0002]

2. Description of the Related Art Conventionally, a circulating coin dispensing and dispensing machine has a coin receiving and dispensing section for separating and dispensing mixed coins which are collectively inserted in a coin receiving slot in a non-aligned state one by one, and one coin dispensed. A coin discriminating unit for discriminating authenticity and the like while transporting each coin, a coin sorting unit for sorting discriminated coins while transporting them, and a coin type coin storing unit for storing the classified coins by denomination; It has a coin-type coin feeding unit for feeding coins one by one from a coin-type coin storage unit to a coin outlet in accordance with a throw-out command in the gold processing.

[0003] Recyclable coin depositing and dispensing machines installed at store cash registers and at the counters of financial institutions require the installation of a cash register machine and the like, so that the height of the circulation coin dispensing and dispensing machine itself is increased. There is a particular demand for reductions. For example, as described in Japanese Unexamined Patent Publication No. Hei 4-111090, the coin storing / feeding unit is constituted by a feeding belt in which the bottom surface of the coin storing unit is stretched up and inclined, as in the prior art. It is known that the height of the device can be suppressed as compared with the case where coins stacked and stored using a coin storage tube (coin tube) in a vertical position (vertical posture) are thrown out from the lowest position of the tube. Have been.

[0004] However, the coin storage and dispensing device using the above-described dispensing belt having an upward slope has the following problems.

At the time of deposit processing, coins classified on the payout belt of the coin storing / feeding section by denomination are simply thrown in at random and are not aligned but are in a state of random piles.
That is, since the coins are the non-aligned storage portion, a gap is formed between the coins, the coin storage efficiency is low, and an increase in the storage capacity leads to an increase in the size of the device.

[0006] Further, since the coin storage capacity varies depending on the state of the pile of coins, the coin storage capacity is an indefinite number of coin storage sections, and it is necessary to provide some storage space for the variation in the number of stored coins.

At the time of dispensing processing, the feeding belt is driven for the first time in accordance with the ejection command, and non-aligned coins in a heap of miscellaneous piles are rearranged one by one on the feeding belt while being crushed one by one by a separation roller (reverse roller). The unwinding coins are fed out of the belt end one by one from the belt. Therefore, to unwind coins in the falling posture from various storage modes of unaligned coins, pay out coins per sheet by the influence of the coin bridge etc. Variations inevitably occur with the same denomination at time. For this reason, the payout of the required number of sheets must always allow for extra time.

In addition, since coins are regulated in a single row by the separation roller and are successively fed out, coins of different denominations have different diameters of coins. . In particular, small 1-yen coins (diameter
26.2mm) and 500 yen coin (34.5mm in diameter)
There is a noticeable time difference in coin payout per sheet.

In order to solve the above-mentioned problems, the present applicant has already disclosed a coin-type coin storing and feeding device in Japanese Patent Application No. 7-319923.

[0010] The principle of this coin-type coin storing and feeding device will be described. As shown in FIGS. 14 (a) and 14 (b), a coin CN receives a coin through a coin input chute 25 into a coin receiving port X of the rotary cylinder 10 in an inclined posture. When the coin is guided and sent, the falling coin C is usually in a state of falling to the bottom 10a of the inner peripheral surface of the cylinder.
N, but since the rotating cylinder 10 is rotating,
The coin CN in the lying posture tries to be inverted from the bottom 10a to the ceiling side together with the inner peripheral surface rotated by the contact friction with the inner peripheral surface, but the laterally oriented coin CN is not completely inverted and slightly reversed. Since it is likely to be reversed in an imbalanced left and right posture, a drag in the direction of twisting the coin surface acts from the inner peripheral surface of the rotating cylinder 10 and a part of the peripheral edge of the twisted coin at the time of the inversion. Although the reversal force of the coin CN weakens due to the re-contact of the inner peripheral surface of the rotating cylinder 10, the rotational torque for rubbing the coin rim in the tangential direction acts to some extent continuously. Therefore, FIG.
As shown in (d), the rotation of the rotating cylinder 10 is normally performed about once or twice, and the reversal of the coin CN is stopped, and the coin CN becomes a forward independent posture due to the rotational inertia. In other words, the independent coin CN '
Starts rotating in synchronization with the rotating cylinder 10 in a state where the coin periphery is in contact with the bottom side of the inner peripheral surface of the rotating cylinder 10.

However, since the rotating cylinder 10 is arranged at a certain degree of inclination, as shown in FIG.
The synchronously rotating forward freestanding coin CN 'descends while sliding from the higher side to the lower side along the generatrix of the bottom side 10a of the inclined inner peripheral surface of the cylinder, stops at the lower end Y, and is stacked there. When the lower end of the rotary cylinder 10 is closed, the lowering of the free standing coin CN 'is stopped here, and coins to be successively inserted are similarly stacked in the free standing posture. Since the rotating cylinder 10 has a certain length, a large number of free standing coins CN 'can be stacked and stored.

As described above, since the rotating cylinder 10 as a coin storage cylinder is not vertically oriented but is substantially oriented horizontally (horizontal posture), constant storage of stacking alignment can be achieved, and the height of the storage unit is increased. Can be greatly suppressed. Further, the drive system for rotating the rotary cylinder 10 can be constituted by a gear mechanism, a friction wheel, or the like, which can simplify the mechanical system as compared with the case where a feeding belt is used for the coin storage unit, and further, the width of the coin storage unit. It also contributes to downsizing. In addition, since the coins are arranged, the coin payout time can be shortened.

[0013]

However, in the coin storing and feeding device using the rotating cylinder 10 disclosed in Japanese Patent Application No. 7-313923, the coin falls down due to the contact friction between the coin and the inner peripheral surface of the rotating cylinder. A coin is given a rotational moment around the edge of the coin, and once self-sustained, it is slid and self-propelled, and stacked and stored in an upright posture. If the friction is intermittent, the falling coin is difficult to stand on its own and tends to slide down on the inner peripheral surface. On the other hand, if the contact friction is too large, the coin will continue to rotate and stop in a state of lying down on the inner peripheral surface in the vicinity of the coin insertion position and sticking to the ceiling side, and will not be able to stand on its own. Therefore, in the self-sustaining process, the strength of the frictional force must be set delicately.

Next, in the skidding process after the self-sustaining, the smaller the frictional force, the easier the skidding. However, the larger the tilt angle of the rotating cylinder, the more difficult the skidding in the self-sustaining posture. Further, when the friction is large, the rotating cylinder cannot be placed horizontally.

However, since the self-sustaining process of coins must be given priority first, no frictional force can be set for skidding, and the inclination angle of the rotating cylinder can only be slightly changed. In each process, the contact friction between the inner peripheral surface of the rotating cylinder and the coin is deeply involved, so the optimization of the contact friction is the most important. However, this also involves the selection of materials, securing of friction resistance, and the inner peripheral surface of the cylinder. Roughness, maintenance of frictional force when foreign substances such as moisture and dust are mixed, etc. are obstacles to practical use, and various uncertainties make it impossible to reliably assure the standing up process and the independent side slip process of the falling coin.

In view of the uncertainty of the self-sustained and self-propelled coins, an object of the present invention is to reliably change the posture of a falling coin at a predetermined position to a forward standing posture. It is an object of the present invention to provide a coin handling machine capable of substantially stacking and storing the coins horizontally.

[0017]

Means for Solving the Problems To solve the above-mentioned problems, first, the means taken by the present invention eliminates the self-sustaining operation and the side-slip operation of the independent posture, and first, the inserted coin is roughly fixed in the rotating cylinder in the falling state. By sliding at a substantially constant speed while maintaining the posture, by hitting an obstacle such as a posture change member or the like, the vehicle is forcibly turned up and brought to a forward standing posture, and at the same time, the standing posture is maintained. That is, the present invention relates to a coin handling machine provided with a rotating cylinder having a tilted posture or a substantially horizontal posture in which the upper end opening is a coin receiving slot, wherein the rotating cylinder extends along a helical winding on an inner peripheral surface thereof. It has a coin feeding ridge provided continuously or discretely, and has a coin contact receiving means in the middle of the hollow or at the lower end of the rotary cylinder.
You. Here, in the case of a rotating cylinder having a completely horizontal posture, there is no distinction between the upper side and the lower side, and any end opening can be used as a coin receiving port. The coin receiving means may be an end wall that rotates integrally with the rotating cylinder itself to close the hollow, or a lever that does not rotate integrally with the rotating cylinder but is inserted into an end opening. It can be an insert. Further, the spiral coin feeding ridge is not limited to one formed continuously, and may be provided discontinuously or discretely.

In the present invention, assuming that the diameter of the coin to be handled is d, the thickness of the coin is t, the inside diameter of the rotating cylinder is D, and the height of the coin feeding projection is h, {d ² + t ² } ^1/2 + h <D <｛(d + t) ² + d ² /
It is preferable to satisfy the following condition: 4｝ / (d + t).

The lead angle β of the coin feeding ridge on the vine winding
Is not too small, not too large, and around 45 ° is appropriate. A rotating cylinder formed with a lead changing type coin feeding protrusion in which the lead angle β monotonically changes (monotonically increases or monotonically decreases) along the axial direction of the inner peripheral surface may be used. Further, the pitch P of the coin feeding ridge is preferably substantially equal to or larger than the coin diameter d in order to make the ridge-to-ridge valley a seating surface for the falling coin. Further, the projection height h of the coin feeding ridge may be about １ ／ of the thickness t of the coin of the rotating cylinder. However, if it is too high, the inner diameter D becomes large and a coin bridge easily occurs.

The spiral coin feeding ridge is not limited to one,
A multi-coin feeding ridge may be provided on the inner peripheral surface. That is, the relationship of L = nP (n: number of lines) is established between the lead L and the pitch P.

In particular, it is preferable to provide two coin feeding ridges on the inner peripheral surface of the rotating cylinder. That is, the two coin feed ridges include a first (front) coin feed ridge and a phase difference of 180 from the first coin feed ridge to the coin receiving side.
And a second (rear) coin feeding ridge adjacent by less than 0 °.

Here, the adjacent interval between the first coin feeding ridge and the second coin feeding ridge on the coin receiving side is a narrow interval smaller than the diameter of the handled coin, and the second coin feeding ridge is provided. The adjacent interval between the coin and the first coin feeding ridge on the coin receiving side is a wide interval larger than the diameter of the handled coin. The lead angle of the coin feed ridge is approximately 45 °, and the phase difference between the first coin feed ridge and the second coin feed ridge on the coin receiving port side is 100 ° to 140 °. preferable.

The cross-sectional shape of the coin feeding ridge is preferably a rectangular shape having an edge in order to hook and push the periphery of the coin, but may be a stepped shape or a cross-sectional shape having a slightly rounded contour. The coin feed ridge is not limited to one integrally formed with the inner peripheral surface of the rotary cylinder, but may be, for example, a spiral metal wire material inserted into the hollow of the rotary cylinder and fixed to the inner peripheral surface. In order to facilitate replacement and positioning of the spiral metal wire material, a winding-shaped positioning groove may be formed on the inner peripheral surface of the rotating cylinder.

As a structure for supporting the long rotary cylinder, a rotary support mechanism that makes rolling contact with the outer periphery of one end and the other end of the rotary cylinder can be employed.

Further, it is possible to use a rotary drive mechanism for rotating the rotary cylinder via a driven wheel provided on the outer periphery of the rotary cylinder. In particular, it is preferable that the rotation drive mechanism is arranged on the coin receiving side.

Further, according to the present invention, in the vicinity of the coin receiving means, one standing coin is stored in synchronization with the rotation of the rotary cylinder.
It is characterized by comprising coin feeding means for feeding out one by one to the outside. The coin dispensing means may have a configuration including coin flipping and discharging means.

It is preferable that the coin storage device having the rotating cylinder has a cassette type structure that can be attached to and detached from the body of the coin handling machine.

[Operation] For example, when a coin is inserted into a coin receiving port of a rotating cylinder having a slightly inclined posture, the coin is inserted between adjacent coin feeding protrusions on the bottom side of the inner peripheral surface of the cylinder near the coin receiving port. A coin is placed on the valley section (seat) in a prone position. Where,
Both ends of the periphery of the falling coin are in contact with the surface of the ridge valley at points farther to the left and right with respect to the cylinder axis direction, and are supported in a cross-linked manner. The rear portion is received by the rotating coin feeding ridge, and is guided and fed in an axially rearward rising posture along the bottom side. In the axial feeding process of the falling coin by the coin feeding ridge, the component force in the rotating direction is also applied, so even if the inner peripheral surface of the rotating cylinder is a smooth surface, the coin in the falling posture rides slightly on the coin feeding ridge at the rear. One shoulder up in the rotation direction. When the inner peripheral surface of the rotating cylinder has roughness, the frictional force increases the state of the one-sided rising coin.

The falling coin which is slid and sent in the axial direction in such a posture collides with coin receiving means provided in the middle of the hollow of the rotating cylinder or at the lower end.

At the time of the collision, the falling coin abuts against the coin contact receiving means at the front portion of the periphery thereof. Immediately before the collision, the falling coin is slightly raised in the rotational direction, and the rear portion of the coin has a coin feeding protrusion. Therefore, when the vehicle collides, the coin feed ridge slides relatively to the front of the back side of the colliding coin, and when the coin is raised forward, a component force in the rotational direction is applied from the coin feed ridge, and The rear portion (lower portion) of the coin periphery is received by the coin feeding protrusion adjacent to the rear side. For this reason,
The collided coins are relatively turned upside down by the coin receiving means, and the lower part of the coin periphery is moved to the end from the coin feeding ridge on the rear side, so that the falling coins are received by the coin receiving means. The posture is forcibly changed to the forward standing posture.

At the same time as the upright posture, the upright coin rotates synchronously with the rotating cylinder by contact with the bottom side of the rotating cylinder or by contact with coin rotating receiving means which rotates synchronously.
Even in the case of a rotating cylinder having a horizontal posture, the upright coin is hardly fallen to the hollow side of the rotating cylinder due to the acquired rotational inertia. This is even more so when the rotating cylinder is inclined and the upright coin leans against the coin receiving means. Here, the coin that rises and rotates rides on the coin feed ridge every time the rotating cylinder rotates, so that the rotating coin is accompanied by vertical vibration in the creepage direction, but only a slight flutter occurs due to the rotational inertia. And never fall.

In this way, when the first coin stands on the coin receiving means side of the rotating cylinder, this first coin becomes the coin receiving means for the next arriving falling coin,
The falling coins placed on the protruding valley collide with the standing coins and stand up and rotate. For this reason, a large number of falling coins inserted into the coin receiving slot of the rotating cylinder are stacked and stored sideways while forcibly rotating in the coin receiving and receiving means side.

In the present invention, as described above, the coefficient of friction between the coin and the inner peripheral surface of the rotating cylinder does not become a factor that introduces uncertainty into the upright rotation of the coin. Since the coin slides in the rotating cylinder in the axial direction, it is preferable that the coefficient of friction is low for the purpose of reducing wear.

Even if the coefficient of friction is low, the one-sided up posture of the falling coin occurs to some extent. If you increase the rotation speed of the rotating cylinder,
As the transport speed of the falling coins increases, the posture of the falling coins rising one shoulder increases. For this reason, the time for stacking coins can be shortened.

The length of the rotating cylinder naturally needs to be equal to or greater than the pitch P of the coin feeding ridge, but if the length of the rotating cylinder is, for example, a short cylinder of about 2 to 3 P, the inserted coin is placed on the ridge valley near the coin receiving port. There may be a case where the coin directly and violently collides with the coin receiving means or the upright stored coin. This is likely to occur when the coin insertion speed or the tilt angle of the rotating cylinder is large. But,
As long as the coins are not thrown in quickly, no bridging or interference between the coins will occur, so even if the thrown coins collide directly with the coin receiving means or the coins that have been stored upright, they will end up as either seat due to recoil. Because it fits in the ridge and valley,
Thereafter, the coins are changed to an upright posture by re-collision with coin receiving means and the like, and are stacked while rotating.

When the rotating cylinder rotates with the front edge of the falling coin resting on the coin feeding ridge, the coin feeding ridge slips away from below the falling coin, so that the periphery of the falling coin is moved. The cover on the front part disappears and naturally fits in the ridge. Conversely, when the rotating cylinder rotates with the rear edge of the falling coin riding deeply on the coin feeding ridge, the coin feeding ridge puts the falling coin and turns it, so the coin has an inclined posture on the side, Overcoming the coin feed ridge, it will fit into the next ridge.

When the rotating cylinder is a long cylinder, the function of stacking upright coins in a horizontal direction (alignment storage function) is sufficiently exhibited,
It has significance as a coin storage tube (coin tube). In such a case, since the rotating cylinder is not in the vertical direction but in the horizontal direction, stacking and stacking of coins and constant storage can be achieved, and the height of the coin storage unit can be significantly reduced. 1 °
Only a slight inclination angle is required, and a substantially horizontal posture is also possible,
A device height dimension (several cm) that is about twice the coin diameter can also be realized. Further, the configuration of the drive system for rotating the rotary cylinder can be simplified as compared with the case where the feeding belt is used for the coin storage unit, and further contributes to the reduction of the width of the coin storage unit.

As described above, since the stacked coins that rise and rotate ride on the coin feeding ridge every time the rotary cylinder rotates, a wave of vertical vibration is generated in the horizontally stacked coin group. Such vertical vibration of the coin is released from the pressing force due to the accumulated load of the coins (decreases as the inclination angle is reduced) for the endmost standing coin on the side of the coin contact receiving means, so to speak in the direction along the surface of the coin. This is helpful in achieving synchronous coin dispensing. In addition, the foreign substances such as dust attached to the coins are rubbed by the coins, and the coins are cleaned and the coin feeding operation of the endmost standing coin is smoothly performed.

Here, when the inner diameter D of the rotating cylinder becomes very large compared to the diameter d of the coin, the frequency of occurrence of bridges between coins (T-shaped bridge of standing coins and falling coins) due to the rapid or simultaneous insertion of coins increases. However, it is desirable to use a rotating cylinder having an inner diameter D and a projection height h that satisfies the following conditional expression.

｛D ² + t ² ｝ ^1/2 + h <D <｛(d +
t) The ^{2 + d 2/4} /} (d + t) such conditions, it is possible to prevent the bridge of coins each other in the rotating cylinder.

The lead angle of the coin feeding ridge is β = tan ⁻¹ (L
/ ΠD), but when the lead angle β is reduced,
Since the lead L is shortened, the transport speed is reduced, and since the component force in the rotation direction is small, the one-side-up posture is weak. Therefore,
It is necessary to increase the rotation speed. Conversely, if the lead angle β is increased, the lead L becomes longer, so that the carrying capacity increases,
In addition, since the component force in the rotation direction is large, the posture of raising one shoulder is strong. The rotating cylinder can be driven at low speed rotation. Usually, the lead angle β is neither too small nor too large, and it can be said that around 45 ° is appropriate.

It is desirable that the inner diameter D of the rotary cylinder satisfies the above-mentioned conditional expression. However, when the lead angle β = 45 °, L = πD, and the coin diameter of one yen is 20 mm and the coin diameter of 50 yen is 21 mm.
mm, 5 yen coin diameter 22mm, 100 yen coin diameter 22.6mm, 10 yen coin diameter 23.
With reference to 5mm, 500 yen coin diameter 26.5mm, lead L is 10c
The length will be around m. Pitch P in one coin feed ridge
= L, the pitch P is too long, and a large play of about 2d in the axial direction can be performed on the falling coins placed on the protruding valleys as seats, and a plurality of lodging coins are placed on the protruding valleys. The probability increases, mutual interference occurs during the coin standing process at the time of collision with the coin receiving means, and the standing operation may fail. For this reason, instead of one coin feed ridge, 2
When a rotating cylinder having a plurality of coin feeding protrusions is used, the number of coins riding on the valleys of the protrusions is reduced, so that the rising operation at the time of collision with the coin receiving means is ensured. In the case of multiple lines, L = nP = πD. Assuming that the pitch P is about the coin diameter d, when the lead L is about 10 cm, the number of strips n is 2 to 2.
About 6 is appropriate.

However, limiting the number of coins placed in the ridge valley means increasing the number of seats in the ridge valley, lengthening the rotating cylinder, and dispersing the number of coins put in a lump. In addition, the processing time (total number of rotations) required to raise all of the plurality of coins that have been put together is increased.

When the falling coin collides with the coin receiving means due to the coin feeding ridge, the above-mentioned manner of raising the colliding coin is determined by setting the front of the coin in the front-up position from below so that the colliding coin is turned over. The coin contact receiving means (surface) is moved upward and the back side of the falling coin overlaps the coin contact receiving means. Here, in addition to the function of feeding the falling coin in the axial direction, when the front portion of the falling coin collides with the coin receiving means, the coin feeding ridge applies a component in the rotating direction to the falling coin and simultaneously moves the colliding side. It has the function of floating. Then, a coin feeding ridge adjacent to the rear side receives the rear portion (lower portion) of the coin and moves to the end. For this reason, when there are multiple coins on the ridge, only the bottom coin that has climbed up on the coin feed ridge is kept in the restraint of forced posture, and the bottom coin rises forward. In the posture, the coins stacked on the coins are in an unconstrained state, so that the coins are fed back to the rear protruding valleys, and it is difficult to realize a large number of coins standing together. In addition, after the front coin feeding ridge has a forward rising posture, the rear portion is brought to the end with the rear coin feeding ridge, so it is difficult to stand up if the forward rising posture is insufficient. However, it is necessary to increase the protrusion height h of the coin feeding ridge to some extent, but the margin of the inner diameter D of the rotating cylinder that can prevent bridging between coins becomes narrower, and the vertical vibration generated in the horizontally stacked coin group is intensified, A new problem such as a point where noise or the like occurs occurs, and it is not preferable to increase the projection height h.

Therefore, the second means of the present invention focuses on the point that two coin feeding ridges adjacent to each other cooperate to erect a collision coin. A second (rear) coin feeding ridge adjacent to the coin receiving port side with a phase difference of less than 180 ° from the first coin feeding ridge is provided on the inner peripheral surface of the rotating cylinder.

When the falling coin is fed in the axial direction with the rear part riding on the first coin feeding ridge, the second coin adjacent to the rear side is fed.
Since the coin feeding ridge has a small phase difference and is close to each other, the rear portion of the falling coin is simultaneously fed in the axial direction while riding on the second coin feeding ridge. That is, the first coin feeding ridge contacts the upper edge of the rising edge of the coin in the rearward rising position, and the second coin feeding ridge continues to contact below the lower edge of the coin. The lower part of the periphery is in contact with the protruding valley. When the front portion of the coin rising rearward in this posture collides with the coin receiving means, the left and right rear portions of the coin are raised upward by the first and second coin feeding ridges with the front portion of the coin as the lower base point, and the upper portion of the coin is raised. Strikes against the coin contact receiving means, the lower part of the coin is edged by the second coin feeding ridge, and the surface of the falling coin overlaps with the coin receiving means. Therefore, even when a plurality of falling coins are conveyed in the axial direction, the coins are flipped at the same time as the collision. Realize.

The upright posture change in which the back side of the rising coin is overlapped with the coin contact receiving means when the distance between adjacent coin feeding ridges is large compared to the coin diameter is easy to occur. The change of the inverted posture, in which the surface side of the falling coin is inverted and then overlapped upon collision with the coin contact receiving means, is likely to occur when the interval between adjacent coin feeding ridges is smaller than the coin diameter. However, if the adjacent distance between the second coin feeding ridge and the first coin feeding ridge on the coin receiving side is smaller than the coin diameter, the second coin feeding ridge and the second coin feeding ridge on the coin receiving side may be used. When there is a case where the falling coins are put on the coin feeding ridge, there is a case where the coins collide in the forward rising posture and the erect posture is changed.

Therefore, the adjacent interval between the first coin feeding ridge and the second coin feeding ridge on the coin receiving side is set to a narrow interval smaller than the diameter of the coin to be handled, and the second coin feeding ridge is If the interval between the coin receiving side and the first coin feeding ridge is set to a wide interval larger than the diameter of the handling coin, coin feeding is performed in a backward rising position in many cases. It does not happen at all and can be stored upright by changing the inverted posture.
In such a case, a large number of sheets can be stored in an upright state, and the rotating cylinder can be shortened or the rotation speed can be reduced.

Next, when a spiral metal wire material that can be externally attached is used as the coin feeding ridge, wear of the ridge can be suppressed due to mutual friction with the coin, and even if worn, the ridge can be used. Can be exchanged, so that maintenance and management costs can be reduced.

As a structure for supporting a long rotating cylinder,
A rotation support mechanism that makes rolling contact with the outer periphery of one end and the other end of the rotating cylinder can be employed. As the length becomes longer, the rotation support of the rotary cylinder becomes easier without eccentricity.

When a rotary drive mechanism for rotating the rotary cylinder through a driven wheel provided on the outer peripheral surface of the rotary cylinder is used, the configuration of the drive system can be simplified. In particular, when a plurality of rotating cylinders are arranged side by side and driven to rotate at once, the rotational force can be transmitted to an adjacent rotating cylinder via a driven wheel provided on the outer peripheral surface. For example, the driving system can be greatly simplified as compared with a case where a common timing belt is wound around all the rotating cylinders arranged side by side and driven to rotate.
In particular, in a structure in which the rotary drive mechanism is arranged on the coin receiving side, the space between the bottom surface of the machine and the coin receiving side of the inclined rotating cylinder can be used as a storage space for the driving source. Therefore, there is no adverse effect that the height of the apparatus is consumed.

Further, the present invention is characterized in that it is provided with coin feeding means for feeding out the standing stored coins one by one in synchronization with the rotation of the rotary cylinder in the vicinity of the coin receiving means. The upright coin at the lower end in the rotating cylinder is eccentric and rotates with some play space, and is accompanied by periodic vertical vibration. Further, since the weight of the stacked coins is hardly applied to the horizontally rotating cylinder, the synchronous feeding operation of one piece per rotation can be easily achieved by utilizing the rotating force of the rotating cylinder itself. By flipping the upright rotated coins with the coin flip-up and ejection means, it is possible to recover the falling difference of the rotating cylinder where the jumping coins are inclined without using special transport means, and reacquire the potential for dropping into the coin outlet it can.

Further, when the coin storage device having the rotating cylinder has a cassette type structure which can be attached to and detached from the body of the coin handling machine, collective collection of coins and improvement of workability at the time of failure / inspection are to be achieved. Can be.

Rotating cylinder 28a of coin storing and feeding section D by denomination
28f are arranged side by side in the same direction of rotation. In order to balance the rotational inertia, the rotating cylinders 28a to 28f
May be rotated in the opposite direction. And
The upper roller support mechanism S1 is composed of three idle rollers R that make rolling contact with the flanged rolling raceway surface L on the outer peripheral surface of the rotating cylinder 28 at three equal points, and these are rotatably supported by a bracket (not shown). Have been. The lower roller support mechanism S2 also includes three idle rollers R that make rolling contact with the flanged rolling track surface L on the outer peripheral surface of the rotating cylinder at three equal points, and these are rotatably supported by the bracket 1a. Have been. Each rotating cylinder 28a to 28f (28)
Has a coin feeding ridge S having a rectangular cross section provided continuously along the vine winding on the inner peripheral surface thereof as shown in FIG. 6, and the lower side end Y of the rotating cylinder 28 is provided with a coin. It is closed by an end pressing plate 41 as a receiving means. As shown in FIG. 6, the rotating cylinder 28 of the present embodiment has a left-handed coin feeding ridge (screw) S continuously provided along the vine winding on the inner peripheral surface thereof.

The rotation drive mechanism G includes a single output spur gear g ₀ of the drive motor M disposed in a space between the bottom of the body and the coin receiving port X of the inclined rotation cylinder 28, and each rotation cylinder 28. a driven spur gear g provided on the upper side of the roll track surface L side of the has an intermediary spur gears g ₁ for rotary transmission between the driven spur gear g, the rotation of the output spur gear g ₀ is one end the rotational force transmitted meshes with the driven spur gear g cylinder 28a, the rotational force is adapted to be transmitted to the driven spur gear g of the subsequent rotary cylinder 28f through the intermediary spur gears g _1. Only the drive motor M is required, which helps to simplify the drive system.

The coin feeding mechanism 36 includes a coin feeding starting solenoid 38, a coin flip-up claw 40 which appears and retracts on the inner periphery of a lower end of the rotary cylinder 28 by a plunger thereof, and an end portion serving as a coin receiving means. The coin flip-up passage 41a of the holding plate 41 has a rubber coin flip-up impeller 42 for feeding the coin CN flipped up to a position above the coin flip-up claw 40 upward and assisting the same. Coins can be easily flipped upward by the coin flip-up claws 40 one by one for each rotation. This is because the stored coins are stacked sideways, so that the lowermost coin is not so much loaded. Therefore, without using a special conveying means, the head of the rotating cylinder in which the jumping coin is inclined can be recovered, and the coin outlet 43 can be recovered.
You can re-acquire the potential to drop into Reference numeral 37 denotes a counting sensor for detecting the passage of the coin CN being fed.

As shown in FIGS. 6 (a-1) to (a-3), when a coin CN is inserted into the coin receiving port X of the rotary cylinder 28 in the inclined posture via the coin input chute 25, the coin receiving is performed. On the bottom side of the inner peripheral surface of the cylinder near the entrance X, the coin CN is placed in the falling posture on the valley section (seat) T sandwiched between the adjacent coin feeding ridges S, S. In such a state, the peripheral edge of the falling coin CN contacts the surface of the protruding ridge T at left and right distant points p, p with respect to the cylinder axis direction, and is supported in a cross-linked manner. Since the rotary cylinder 28 is rotating in the direction of the arrow in such a state that the left and right ends are supported, the rear two points or 1
The point Q comes into contact with the rotating coin feeding ridge S, receives a pushing force F in the normal direction, and is guided and fed along the bottom side by the axial component force.

In the process of feeding the falling coin CN in the axial direction by the coin feeding ridge S, a component force in the rotating direction is also applied. Therefore, even if the inner peripheral surface of the rotating cylinder 28 is a smooth surface, FIGS.
As shown in -3), the coin CN in the lying posture is slightly up in the rotation direction. If the inner peripheral surface of the rotating cylinder has roughness, the frictional force increases the state of the one-sided rise of the falling coin CN. The falling coin CN which is slid in the axial direction in such a posture is the lower end Y of the rotary cylinder 28.
Will collide with the end holding plate 41 provided in the above.

As shown in FIGS. 6 (c-1) to 6 (c-3), at the time of this collision, the falling coin CN comes into contact with the end holding plate 41 at the front part of the periphery thereof. CN
Is slightly elevated in the rotation direction, and the rear edge of the coin is in a state of climbing over the coin feeding ridge S, so when colliding, the coin feeding ridge S slides into the front side on the back side of the colliding coin, At the same time as the colliding coin is in the forward rising posture, a component in the rotational direction is applied from the coin feeding ridge S, and the rear (lower) portion of the coin periphery is received by the coin feeding ridge S adjacent on the rear side. For this reason, the collision coin CN is relatively turned upside down by the end pressing plate 41, and FIG.
As shown in FIG. 7A, the rear portion of the coin periphery is moved closer to the edge than the coin feeding ridge S, so that the falling coin CN is forcibly raised by the end pressing plate 41 as shown in FIG. Changed to posture.

At the same time as the upright posture is set, the upright coin CN 'is brought into contact with the bottom side of the rotating cylinder 28 so that
The coins CN 'hardly fall to the hollow side of the rotating cylinder 28 due to the acquired rotational inertia even in the case of the rotating cylinder 28 in the horizontal posture. Standing coin CN '
This is all the more so in the state where is leaning on the end pressing plate 41. Here, the coin CN 'which rises and rotates rises on the coin feed ridge S every time the rotary cylinder 28 rotates, so that the rotating coin is accompanied by a vertical vibration in the creeping direction. It only sticks and does not fall.

When the first coin stands up on the end holding plate 41 of the rotary cylinder 28 in this way, the first coin serves as coin receiving means for the next arriving falling coin CN, and the ridge and valley is formed. The falling coin CN on T is the standing coin C
The vehicle collides with N 'and stands up and rotates. For this reason,
As shown in FIG. 7C, the coin receiving port X of the rotating cylinder 28
The large number of lodging coins CN inserted in the
It is stored sideways while standing and rotating on the side.

In the present embodiment, the coefficient of friction between the inner peripheral surface of the rotary cylinder 28 and the coin CN does not become a subtle factor in the upright rotation of the coin. Since coins slide in the rotating cylinder 28 in the axial direction, it is preferable that the coefficient of friction be low for the purpose of reducing wear. However, it is not a surface contact, but FIGS.
As shown in 3), since the sliding occurs at the point contact of the left and right ends P, P in a supported state, the problem of wear is not serious. Even with a low coefficient of friction, the one-side-up posture of the falling coin CN during sliding occurs to some extent. When the rotation speed of the rotary cylinder 28 is increased, the transport speed of the falling coins CN is increased, and the posture of the falling coins CN is increased by one shoulder. For this reason, the time for stacking coins can be shortened. However, if the coins are rotated at a high speed, the coins may stand on their own, or stick to the inner peripheral surface in a lying posture, and may stop. Therefore, it is necessary to avoid excessive high-speed rotation. Conversely, if the rotation speed is much lower than 1 rps, the collision speed is slow, and the coins during the erecting process are slowed down. .

Here, the length of the rotary cylinder 28 needs to be equal to or longer than the pitch P of the coin feeding ridge S. For example, if the length of the rotating cylinder 28 is a short cylinder of about 2 to 3 P, the inserted coin will A case may occur in which the end pressing plate 41 or the upright stored coin CN 'directly collides vigorously without being placed on the valley T. This is likely to occur when the coin insertion speed or the inclination angle (downward inclination angle) of the rotating cylinder 28 is large. However, as long as the coins are not thrown in early, the bridges and interference between the coins do not occur. Therefore, even if the thrown coins directly collide with the end holding plate 41 or the upright stored coin CN ′, the coins eventually return due to the recoil. Since the coins fit in the protruding valleys T as the seats, the coins are surely changed to the upright posture by re-collision with the end holding plate 41 or the upright stored coins CN ', and are stacked while rotating. .

When the rotating cylinder rotates with the front edge of the falling coin resting on the coin feeding ridge, the coin feeding ridge slips through in a direction away from below the falling coin, so that the peripheral edge of the falling coin is moved. The cover on the front part disappears and naturally fits in the ridge. Conversely, when the rotating cylinder rotates with the rear edge of the falling coin riding deeply on the coin feeding ridge, the coin feeding ridge puts the falling coin and turns it, so the coin has an inclined posture on the side, Overcoming the coin feed ridge, it will fit into the next ridge.

If the rotary cylinder 28 is a long cylinder, the coins CN 'standing upright can be stacked horizontally (alignment storage function).
Is fully exhibited, and the significance as a coin storage cylinder comes out. In such a case, since the rotating cylinder 28 is not in the vertical direction but in the horizontal direction, it is possible to achieve stacking and stacking of coins and to store the constants, and to greatly reduce the height of the coin storage unit.

Further, the rotating cylinder 28 may be in a substantially horizontal posture, and the height of the apparatus about twice the coin diameter can be realized.
Further, the configuration of the drive system for rotating the rotating cylinder can be simplified as compared with the case where a feeding belt is used for the coin storage unit, and also contributes to the reduction in the width of the coin storage unit.

As shown in FIG. 7 (c), the stacking coins which rise and rotate rotate each time the rotary cylinder 28 rotates.
, A vertical vibration wave is generated in the horizontally stacked coin group. Such vertical vibration of the coin CN ′ is released from the pressing force due to the accumulated load of the coins (decreases as the inclination angle becomes gentler) for the endmost standing coin CN ″ on the side of the end pressing plate 41, thereby releasing the coin surface. This helps to achieve synchronous feeding of coins in a manner similar to a creepage in the creepage direction, and also rubs off foreign substances such as dust adhering to the coins CN 'with each other so that the coins can be cleaned and the outermost end. The coin dispensing operation of the upright coin.

Next, the condition of the inner diameter D of the rotating cylinder 28 with respect to the diameter d of the coin to be handled will be examined.

First, as shown in FIG. 8A, in order to prevent the coin from bridging between the top surface of the coin feeding ridge S and the inner peripheral surface of the rotating cylinder 28 facing the coin feeding ridge S, the coin feeding ridge S is required. Assuming that the height of the protrusion of S is h and the thickness of the coin is t, the inequality {d ² + t ² } ^1/2 + h <D. Further, when the inner diameter D increases, the frequency of occurrence of bridges between coins (T-shaped bridges of standing coins and falling coins) as shown in FIG. 7B increases due to the rapid insertion of coins. to bridge does not occur, D <{(d + t ) 2 + d 2/4} / (d + t) ... inequality holds for. After all, the following equation is established from the equation. With ^{{d 2 + t 2} 1/2} + h <D <{(d + t) 2 + d 2/4} / (d + t) ... rotary cylinder 28 this expression is satisfied, it is possible to eliminate the occurrence of coin bridge.

Here, the inner diameter of each coin is calculated assuming that h = t / 2, as follows. The inner diameter D ₁ of the 1 yen coin (20 mm diameter, 1.5 mm thickness) is, 20.8 mm <D ₁ <inner diameter D ₅₀ of 26.2 mm 50 yen coins (21 mm diameter, 1.75 mm thickness) is, 21.9 mm <D ₅₀ <27.6 mm 5 yen coin (22 mm diameter, 1.5 mm thickness) is the inner diameter D ₅ of, 22.8mm <D ₅₀ <inner diameter D ₁₀₀ of 28.6 mm 100-yen coin (22.6 mm diameter, 1.7 mm thickness) is, 23.5mm <D ₁₀₀ <29.6 The inner diameter D ₁₀ of a 10-yen coin (23.5 mm diameter, 1.5 mm thick) is 24.3 mm <D ₁₀₀ <30.5 mm ₅₀₀ The inner diameter D ₅₀₀ of a 2 yen coin (26.5 mm diameter, 1.8 mm thick) is 27.4 mm <D ₅₀₀ <34.5 mm Therefore, as the rotating cylinders 28a to 28e of coins of 1 yen, 50 yen, 5 yen, 100 yen, and 10 yen, the inner diameter is 24.3 mm or more and 2 yen.
A common pipe of 6.2 mm or less can be used. For this reason,
The number of dissimilar parts can be reduced, which contributes to a reduction in the cost of the apparatus and also helps to reduce the size of the width of the cylinders. If the protrusion height h is about 3 mm or more, the common range of the inner diameter is lost, and a common thin tube cannot be obtained. Therefore, the protrusion height h of about t / 2 to 2t is appropriate.

As shown in FIG. 9, the lead angle of the coin feeding ridge S is given by β = tan ⁻¹ (L / πD). However, when the lead angle β is reduced, the lead L becomes shorter, and the transport speed is reduced. In addition, since the component in the rotation direction is small, the posture of raising one shoulder is weak. Therefore, it is necessary to increase the rotation speed. vice versa,
When the lead angle β is increased, the lead L becomes longer, so that the carrying capacity is increased. In addition, since the component force in the rotating direction is large, the one shoulder rising posture is strong. The rotating cylinder 28 can be driven at low speed rotation. Lead angle β is not too small, not too large, typically 45
° is reasonable.

It is desirable that the inner diameter D of the rotary cylinder 28 satisfies the above equation, but the lead angle β = 45 °
In the case of L = πD, 1-yen coin diameter 20mm, 50-yen coin diameter
21mm, 5 yen coin diameter 22mm, 100 yen coin diameter 22.6mm, 10 yen coin diameter
With reference to 23.5mm, 500 yen coin diameter 26.5mm, lead L is
It will be around 10cm long. Since the pitch P = L in a single coin feeding ridge, the pitch P is too long, and a large play of about 2d in the axial direction can be made on the falling coin placed on the ridge T as a seat. The probability that a plurality of lodging coins will be placed on the valley T increases, and mutual interference occurs during the coin erecting process at the time of collision, and the erecting operation may fail.

For this reason, as shown in FIG. 10, not a single cylinder, but a rotary cylinder 2 having two or more coin feeding projections S.
By using 8, such inconvenience can be solved. In the multiple case, L = nP = πD. If the pitch P is about the coin diameter d, n is suitably about 2 to 6.

The coin feeding ridge S of the rotating cylinder 28 shown in FIGS. 9 and 10 is a spiral metal wire material inserted into the inner peripheral surface of the rotating cylinder 28. Although it is difficult to integrally form the coin feeding ridge S in the rotary cylinder 28 by casting, extrusion, cutting, or the like, when a spiral metal wire material having an outer diameter slightly larger than the inner diameter D is inserted. The rotating cylinder 2 with the coin feeding ridge S can be pressed against the inner peripheral surface by its self-restoring force
8 can be easily obtained. The rubbing of the ridges can be suppressed by mutual friction with coins, and the ridges can be replaced even if worn, so that maintenance management costs can be reduced. Note that a spiral positioning groove may be provided on the inner peripheral surface of the rotating cylinder 28.

Both ends of the elongated rotary cylinder 28 in this example are supported by roller support mechanisms S1 and S2. The longer the rotary cylinder 28 is, the easier the rotary cylinder 28 can be supported for rotation without eccentricity, and is suitable as a support structure.

Each rotary cylinder 28 is driven to rotate via a driven spur gear g provided on its outer peripheral surface. Simplification of the drive system has been achieved. In particular, in this example, since the rotary drive mechanism is arranged on the coin receiving port X side, the motor M and the like are provided in a space between the bottom surface of the body and the coin receiving port X side of the inclined rotating cylinder 28. It can be stored and contributes to effective use of space.

Further, in this embodiment, the coin feeding mechanism 36
Are fed using the rotation of the upright coin CN by the rotation of the rotary cylinder 28, so that the configuration of the mechanism can be simplified. In addition, since the coin CN that has been rotated upright can be ejected so as to be flipped up, the falling difference of the inclined rotating cylinder 28 can be recovered, and the potential for dropping the coin into the coin outlet can be obtained again. For this reason, it is not necessary to use a transport device after feeding.

In addition, since the coin storing / feeding section D by coin type has a cassette type structure that can be attached to and detached from the machine body, it is possible to collectively collect coins and improve workability at the time of failure and inspection.

[Embodiment 2] FIG. 11A is a vertical sectional side view showing a rotary cylinder according to Embodiment 2 of the present invention.
(B) is a front view thereof.

[0087] the inner peripheral surface of the rotating cylinder 48 of the present embodiment, the coin dispensing ridge S _a of the first helical (front), to the coin receiving port X side by the first coin feed protruding S _a Phase difference θ = 120
The spiral second (rear side) coin feed ridge S _b adjacent at °
Is provided, and although the spiral is a double spiral, the phase difference is not 180 ° but an unequal phase difference. The first coin feed ridges S _a and the second coin feed protruding S _b is formed with a helical metal wire material.

[0088] When multiple coins CN to the coin receiving port X of the rotary cylinder 48 is turned, as shown in FIG. 12 (a-1), sandwiched coin dispensing ridges S _b and S _a near coin receiving port X A plurality of coins CN are placed in the raised valley section (seat section) T in a rear-up position in which the coins partially overlap. Axial advance is being, but the second coin feed ridges S _b of the rear adjacent the first coin feed collision at the last coin CN ₀ is a state where the rear is riding on the first coin feed protruding S _a due to the proximity to the strip S _a, the rear portion of the last coin CN ₀ is axial advance in a state of simultaneously riding on the second coin feed ridges S _b. That is, any one of the rear part of the coin CN ₀ among the entered plurality of coins becomes raised position after riding on the first coin feed ridges S _a and the second coin feed ridges S _b, then shoulder up first the upper f ₁ of the side peripheral edge of the coin feeding ridges S _a coin CN ₀ of rising posture contacts the support, the lower f ₂ of the shoulder edge side peripheral edge of the coin CN ₀
In continues to contact the second coin feed ridges S _b, the lower portion of the peripheral edge is in contact with the ridges between the valleys T. Up coin CN ₀ After such posture will convey Te boost a plurality of coin CN partly overlapping in the axial direction.

When the leading coin CN collides with the upright stored coin CN "as a coin receiving means, the stacking margin of the coin group is widely stacked, but is shown in FIGS. 12 (a-2) and (b-2). As shown in FIGS. 12 (a-3) and 12 (b-3), the left and right rear portions of the last coin CN ₀ are formed by the first and second coin feeding ridges S _a S _b with the front portion of the leading coin CN as a lower base point. 12 (a-4) and (b-4).
As shown in the figure, the upper portion of the leading coin CN 'is
N "leans on the coin and the coin is inverted.

Then, the last coin C just before the standing up
N ₀ since the lower portion of 'the edge shifting by the second coin feed ridges S _b, upright housing already coin CN "to the deposited coin is a coin of the surface upright housing already coin CN in conveying overlapping with all upright posture"
Overlaps the surface of.

As described above, even when a plurality of the falling coins CN are conveyed in the axial direction, the coins are once inverted and returned to the inverted posture at the same time as the collision. Simultaneously with the reversal operation of the coin CN _0, the stacked coins on the upper side are also reversed, so that a large number of coins are erected at once. Therefore, even if a large number of sheets are loaded at one time, they can be raised at once in an overlapping state, so that the rotating cylinder can be shortened. In addition, in the edge shifting operation after the collision, since the operation can be performed slowly without applying momentum, the rotation speed can be reduced, which leads to low power consumption and low noise.

In the first embodiment, the upright posture is changed so that the back side of the forward rising falling coin is overlapped when it collides with the coin contact receiving means or the like. This is likely to occur when the interval (pitch) between the adjacent coin feeding ridges is larger than the coin diameter d, but in this example, when the front side of the rising and falling coin hits the coin receiving means or the like. This is a change of the inverted posture that is repeated after turning over. This is compared with the coin diameter d and the first coin feeding ridge S _a
It tends to occur when the interval between the second coin feed ridges S _b of the adjacent coin receiving port X side is small and. However, the second coin feed protruding S _b and the first coin feed ridges S _a of the coin receiving port X side
If the adjacent intervals is less than the coin diameter d, a second coin feed protruding S _b and the first coin feed ridges S _a and fallen coin CN straddling the coin receiving port X side rests with At times, the vehicle may collide in a forward rising posture and change the erect posture.

[0093] Therefore, the first coin feed protruding S _a and the second coin feed protruding small closely spaced than the diameter d of handling coins adjacent distance between S _b of the coin receiving port X side, the second when the coin dispensing ridges S _b and the wide-interval greater than the diameter of the adjacent spacing handling coins and the first coin feed ridges S _a of the coin receiving port X side, often, coins rearwardly upwards posture Since the feeding is performed, the upright posture change hardly occurs, and the upright posture can be changed and stored.

In this case, a large number of sheets can be stored in an upright state, and the rotating cylinder can be shortened or the rotation speed can be reduced.

[0095] Normally, coin dispensing ridges S _a, since the lead angle β of S _b are substantially 45 °, of the coin receiving port X side with respect to the first coin feed protruding S _a second coin feed ridges the phase difference between the S _b is suitably 100 ° to 140 °.

In the coin handling machine of the present invention, the coins are not limited to domestic and foreign coins, but include a storage device for stacking medals and the like used in game machines and the like.

Further, the rotating cylinder as the coin storage cylinder according to the present invention is not limited to the horizontal stacking of coins, and it is possible to feed out standing coins immediately before stacking. Function as a standing device,
Further, in a configuration in which the coin receiving means is omitted, the coin functions as a coin conveyor for descending inclined conveyance, horizontal conveyance, and ascending inclined conveyance.

[0098]

As described above, according to the present invention, coins are slid at a substantially constant speed in a substantially horizontal posture in a rotating cylinder in a lying state, and a coin contact receiving means or the like is provided. By hitting an obstacle, the user is brought to an upright or inverted posture, and at the same time, the standing posture is maintained. Therefore, the following effects are obtained.

(1) It is possible to forcibly change the inserted coin from the lying posture to the standing posture without being largely influenced by the delicate value of the friction coefficient between the rotating cylinder and the coin and its fluctuation, and to stack the coins sideways. Storage can be realized. It is possible to realize alignment and storage of a fixed number of sheets, and to significantly reduce the height of the apparatus.

In the horizontally stacked coin group that rotates in the standing posture, the coins are periodically climbed on the rotating coin feed ridge.
Vertically stacked waves are generated in the coins stacked sideways. The vertical vibration helps to achieve synchronous feeding of the endmost standing coin. In addition, foreign objects such as dust attached to the coins are rubbed by the coins, and the coins are cleaned, so that the operation of feeding the endmost standing coins becomes smooth.

(2) {d ² + t ² } ^1/2 + h <D <
^{{(D + t) 2 +} d 2/4} / With rotary cylinder satisfies the formula (d + t), can be prevented coin bridges in the rotary cylinder, it is possible to rapid-fire or batch of insertion of coins, upright housing Efficiency is improved.

(3) The use of a rotating cylinder having a plurality of coin feeding ridges can eliminate the number of falling coins in the valley between the ridges, thereby suppressing interference between coins and increasing the length of the lead. Therefore, the degree of freedom in setting the lead angle is increased, and the upright storage operation can be speeded up.

(4) In a rotating cylinder having a first coin feed ridge and a second coin feed ridge adjacent to the coin receiving port side with a phase difference of less than 180 ° by the first coin feed ridge,
At the time of collision, the surface of the conveyed coin is changed to the inverted posture in which the coin overlaps with the coin contact receiving means and the like, so that the stacked coins can be flipped at a stroke, and the rotating cylinder can be shortened or the rotation speed can be reduced.

(5) In particular, the interval between the first coin feeding ridge and the second coin feeding ridge on the coin receiving side is a narrow interval smaller than the diameter of the handled coin, and the second coin feeding ridge is provided. If the distance between the coin and the first coin feeding ridge on the coin receiving side is a wide distance larger than the diameter of the coin to be handled, the upright posture change is unlikely to occur, the frequency of the inverted posture change is increased, and the upright storage efficiency is increased. Increase.

(6) If an external spiral metal wire is used as the coin feed ridge, the ridge can be prevented from being worn out and can be replaced even if worn out.

(7) As a structure for supporting the rotating cylinder,
When adopting a rotation support mechanism in which one end side and the other end side of the rotary cylinder are in rolling contact with the outer periphery thereof, the longer the rotary cylinder becomes, the easier it becomes to support the rotary cylinder without eccentricity and suitable as a support structure. It will be.

(8) The configuration of the drive system can be simplified by using a rotary drive mechanism that rotates the rotary cylinder via a driven wheel provided on the outer peripheral surface of the rotary cylinder. In particular, in a structure in which the rotary drive mechanism is arranged on the coin receiving side, the space between the bottom surface of the machine and the coin receiving side of the inclined rotating cylinder can be used as a storage space for the driving source. Therefore, there is no adverse effect that the height of the apparatus is consumed.

(9) In the case where a coin dispensing means is provided near the coin receiving means for dispensing upright stored coins one by one in synchronization with the rotation of the rotary cylinder, the rotational force of the rotary cylinder itself is used. Thus, the synchronous feeding operation of one sheet per rotation can be easily achieved. In particular, if the coin that has been turned upright is flipped up by the coin flip-up and ejection means, the jumping coin can recover the falling difference of the inclined rotating cylinder, and the potential for dropping the coin into the coin outlet can be reacquired. Equipment can be eliminated.

(10) When the coin storage device having the rotating cylinder has a cassette type structure that can be attached to and detached from the body of the coin handling machine, it is possible to collectively collect coins and improve workability at the time of failure and inspection. it can.
