Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a coin stacking device used in a coin processing machine such as a coin packaging machine or a circulation type coin depositing / dispensing machine. The present invention relates to a coin stacking device for vertically stacking coins conveyed one by one on a coin passage surface by a transfer means in a coin stacking space portion at the end of a coin passage.

(Prior Art) Conventionally, for example, in the case of a coin wrapping machine, after counting a predetermined number of coins, the coins are introduced into a coin aligning cylinder as a coin stacking device to be in a stacking state and then delivered to a wrapping unit and wrapped with wrapping paper. It is designed to do.

The coins are introduced into the aligning cylinder so that the coins introduced from the upper opening of the aligning cylinder are stacked on the receiving plate closing the lower end opening of the aligning cylinder while falling. .

Also, in the case of the circulation type coin depositing / dispensing machine, the depositing coins or the supplementary coins for dispensing are sorted and stored in the respective denomination aligning cylinders facing the respective sorting holes in the coin passage. The coin-type arranging cylinders are provided with ejection plates at their lower openings, and coins fed into the arranging cylinders are dropped by their own weight and stacked on the ejection plates.

In each of the above-mentioned related arts (hereinafter referred to as the first related art), since there is a problem described later, a receiving plate that is moved up and down by a cam is provided in the coin aligning cylinder so that coins can enter the coin aligning cylinder. Then, the receiving plate is sequentially lowered to form a constant space between the coin passage surface and the upper surface of the stacked coins, thereby facilitating the feeding of coins. There is).

(Problems to be solved by the invention) In the first prior art described above, however, when the stacking amount of coins is set to be large, the falling distance of the coins becomes large, and the coins fall between the aligned cylinders while falling. When it hits the inner peripheral surface, it becomes an upright posture, a so-called cylinder standing phenomenon occurs, it is difficult to obtain a good stacking posture, and there is a problem that the subsequent packaging process cannot be performed normally.

The second prior art is made in order to eliminate the problems of the first prior art. However, in the second prior art, the receiving plate is obtained by electrically detecting the entrance of coins into the coin aligning cylinder. It is necessary to electrically control the descent of the coins, and if the feeding speed of the coins into the aligning cylinder is increased, the responsiveness deteriorates, and there is a problem that defective coin stacking frequently occurs.

Further, in each of the above-mentioned conventional techniques, since coins are stacked below the coin passage surface, there is a drawback that the installation position of the coin stacking device is restricted when applied to a coin wrapping machine. The discharging position of the packed coins of the coin packing machine is at a very lower position, which makes it difficult to carry out.

Therefore, the coin stacking space portion is formed above the coin stacking surface portion that is formed at substantially the same height as the coin passage surface, and the leading edge of the coin fed into the coin stacking space portion by the coin transfer means. The leading edge abutting portion of the coin with which the abutting contacts the trailing edge of the coin that displaces the trailing edge of the coin in the coin stacking direction by contacting one surface of the coin when the abutting portion is pushed by the abutting coin. We have developed a coin stacking device equipped with a coin feeding member in which a plurality of displacement parts are provided alternately, and both parts alternately appear and disappear in the coin stacking space part. Even if the problems of the first and second prior arts are solved, the stacking failure of coins may occur during the stacking operation of coins in the stack space of coins. The occurrence of stacking failure causes a problem that the coins are immediately jammed, and when the coins are jammed, it becomes difficult to discharge the jammed coins.

The present invention has been made for the purpose of providing a coin stacking apparatus capable of solving the above-mentioned problems in the developed technology as well as the problems in the first and second conventional technologies.

[Constitution of device]

(Means for Solving Problems) In order to solve the above problems of the prior art, the present invention provides a coin weight for vertically stacking coins conveyed one by one on a coin passage by a coin transfer means. In the stacking device, a coin stacking surface portion that faces the end of the coin passage, is formed at substantially the same height as the passage surface, and forms a bottom portion of the coin stacking space portion,
A plurality of coin stacking space forming members forming upward coin stacking space portions on the stacking surface portion, and coins with which the leading edges of the coins fed into the coin stacking space portion by the coin transfer means come into contact. Tip edge abutting part, and coin rear end edge that when pressed by an abutting coin, contacts the lower surface of the coin and displaces the coin rear end edge upward from the upper surface of the coin stacking surface part. A plurality of displacement parts are provided alternately, and both parts move alternately into and out of the coin stacking space part, and at least one of the coin stacking space forming members is moved in the diameter expansion direction. An electric drive unit, a detection unit provided facing the coin passage, for detecting the stoppage of the flow of coins during the coin counting operation, and the coin stacking surface portion and the coin feeding member are retracted from the lower part of the coin stacking space. Second electric drive unit and coin by the detection means Is characterized in that it comprises a control unit for actuating the second electrical drive unit in the mixture was allowed to operate the first electric drive unit when the flow stop detection coins in several operations.

(Operation) With the above-described configuration, the coins fed into the coin stacking space by the coin transfer means are sequentially stacked upward in the order of coin feeding through the coin feeding member. Further, when the coin counting operation is detected by the detection means for detecting the stoppage of the flow of coins when the coins flow through the coin passage, it is judged that the coin stacking is defective and the coin stacking space is formed. By moving at least one of the members in the radial expansion direction and then retracting the coin stacking surface portion and the coin feeding member, the defective stacking coin is automatically excluded from the coin stacking space portion.

FIG. 20 shows a control block diagram, which has a control unit 100 for controlling the drive motor of each unit, and this control unit 100 detects abnormality of the counting sensors S ₁ , S ₂ , sensors S ₃ , S ′ ₃ . It is connected to an abnormality detecting unit 101 for detecting a signal, and when these sensors detect an abnormality, it causes the control unit 100 to operate each unit as follows. The sensors S ₁ and S ₂ and the abnormality detection unit 101 constitute the detection means in the present invention.

1) When counting 50 coins When the sensor S ₁ counts 50 coins, the stopper 16 protrudes to stop the subsequent coins, but a predetermined time has elapsed after the sensor S ₁ outputs a stop signal for counting 50 coins. Even when the sensor S ₂ is blocked by the coin, it is determined that the signal is a stacking failure signal, and the abnormality detection unit 101 outputs the signal to the control unit 100.

2) During counting operation (while counting 1 to 50 sheets) When _{one of} the sensors S ₁ and S ₂ is blocked by a coin for a predetermined time, the abnormality detection unit 101 sends a stacking fault signal to the control unit 100.
Output to.

3) Same as above When the counts of the sensors S ₁ and S _{2 do} not match during counting operation (during chattering), the abnormality detection unit 101 also outputs a stacking failure signal to the control unit 100.

When the above-mentioned stacking failure occurs, 1) The reverse rotation of the motor M ₃ causes the reverse rotation of the conveyor belt 21 for a predetermined time. If the stopper 16 is protruding, retract the stopper.

2) Rotate the denomination setting motor Mc to open the packaging roller and coin passage to the maximum.

3) While the coin feeding member 24 is normally rotated through the motor M ₄ , the moving motor M ₁ of the moving table 27 is rotated to move the moving table 27 out, and the coin is removed and then returned.

In addition, a buzzer alarm or the like is given to the operator if necessary.

Next, the operation of the above embodiment will be described.

When the denomination of the coin to be handled is set by the selection button, the denomination setting motor Mc is rotated, the movable passage member 19 is moved by the rotation of the cam 18 of the denomination setting shaft 4, and the passage width of the coin passage 15 is the denomination. While the width is set to be suitable for passing coins, the cam surface 47A corresponding to the set denomination of the denomination-based height setting cam 47 faces above the roller 46. The cam of the denomination setting axis 4
If the coin to be handled is a large-diameter coin through 18A, the arm 58 is swung as shown in FIG. 11 to move the packaging roller 11 on the movable passage member 19 side in the direction away from the coin stacking space 9. The space portion 9 is expanded, and in the case of a small-diameter coin, the packaging roller 11 approaches and the stacking space portion 9 is reduced as shown in FIG. At this time, since the packaging control cam shaft 43 is stopped at the fixed position, the packaging roller 10 is stopped at the same position in FIGS. 11 and 13, and the packaging roller 12 is a position fixing roller, so the position is It is in a fixed state.

Regarding the stacking of large-diameter coins corresponding to FIG. 11, the motors M ₂ and M ₃ are rotated to rotate the rotating disk and the conveyor belt 21. By the rotation of the rotary disk 13, coins supplied on the rotary disk 13 are aligned in a row along the peripheral wall 14 by centrifugal force, and are further layered by a thickness regulating member (not shown) and then fed into the coin passage 15. When the coin C is sent by the conveyor belt 21 and reaches the end of the coin passage 15 (FIG. 15 (A)), the leading edge of the coin C is brought into contact with the coin leading edge contact portion 24 of the coin feeding member 24.
When the coin hits A, the coin feeding member 24 advances while rotating clockwise in the figure as shown in FIG. 15 (B). At this time, the shaft 26A is in a rotation stopped state, and only the coin feeding member 24 rotates via the one-way clutch 26B. At this time, one end of the coin C is moved to the side of the packaging roller 12 whose position is fixed by the guide plate 62A, and the position of the packaging roller 12 side is regulated by the guide member 64 to proceed.

As the coin feeding member 24 rotates, the coin rear end edge displacement portion 24B of the coin feeding member 24 hits the rear lower surface of the coin C and pushes it up (FIG. 15 (C)), and the coin feeding member 24 The contact portion 24A of 24 is rotated by pushing the pressing roller 53 of the pressing mechanism 51. Then, the displacement portion 24B of the coin feeding member 24 is the coin C.
The rear end of the coin C is shifted, and at the same time, the upper surface of the coin C is pressed by the pressing mechanism 51.
It is held down by the roller 53 (Fig. 15 (E)).

Before the first coin C hits the striking plate 60 and stops, the next coin C hits the coin tip edge contact portion 24A of the coin feeding member 24,
In the same manner as above, the contact portion 24A is pushed to push the coin feeding member 2
Since 4 is rotated, the tip of the abutting portion 24A sends the coin C ahead of it further forward (FIG. 15 (F)), and the tip edge of the coin C abuts against the abutting plate 60. The next-ranked coin advances under the condition that it goes under the preceding coin C (Figs. 15 (G) to (H)).

In this way, as shown in FIGS. 15 (J) and 15 (K), the coins are sequentially stacked from below, and as the stacking height gradually increases, the roller 53 of the coin pressing mechanism 51 pressing the upper surface thereof is pushed up. , When the stack height reaches a specified value,
Since it exceeds the speculation point, the lever 52 falls outward as shown by the chain line in FIG. 15 (K), the pressing roller 53 retreats from the upper surface of the coin C, and is retained by the pin 27a of the moving table 27. . After that, the weight of the stacked coins is stabilized in place of the pressing roller 53, and finally, a fixed number (for example, 50) of coins are stored in the packaging roller as shown in FIG. 15 (L). They are stacked side by side along the striking plate 60.

In FIG. 15 (L), when the 50th coin is detected by the sensor S ₁ , the stopper 16 advances into the passage to stop the subsequent coins and the forced rotation of the conveyor belt 21 is cut off. The second coin is the inertial movement of the coin itself and the conveyor belt 21.
The coin feeding member 24 is rotated by the inertial rotation of to dig into the underside of the 49th coin. However, if the amount of rotation of the coin feeding member 24 is not sufficient, the 50th coin (the lowest coin in FIG. 15 (L)) sneaks into the underside of the 49th coin and stops halfway. Becomes Then, when the sensor S ₁ detects the 50th coin, the motor M ₄ is temporarily driven to rotate the shaft 26A, and the one-way clutch 26B is driven to rotate to temporarily rotate the coin feeding member 24, As shown in FIG. 15 (M), the 50th coin is also completely fed to the abutting plate 60 position.

When the stacking of a certain number of coins (for example, 50 coins) is completed,
The packaging motor is rotated by a signal from the counting unit in FIG. 20, the rotation of the packaging motor is rotated by the cam shaft 43 for performing one packaging cycle in one rotation in FIG. 1, and the rotation of the packaging motor is performed by the packaging roller 10, Drive 11 and 12 to rotate. This camshaft
The rotation of the cam 44 of 43 causes the arm 40 to swing in the upward direction by the force of the spring 45, and the roller 46 of this arm 40 causes the cam surface 47 of the cam 47 to move.
When the arm 40 comes into contact with A, the swinging of the arm 40 in the upward direction is stopped.

The swinging motion of this arm 40 in the upward
The lower support rod 37 is raised via the protruding arm 38 on the top 41, the lower surface of the stacked coin is supported, and the stacked coin is packed at the packaging position (15th position).
(M) A stacking coin position indicated by a two-dot chain line in FIG.

At the coin stacking position (the stacking coin position shown by the solid line in FIG. 15 (M)), the stacking coins that are inclined and shifted stepwise in the coin feeding direction are moved up to the packing position by the lower support rod 37. At times, it is raised along the peripheral surface of the packaging roller 10 and aligned in a columnar shape. Immediately after the lower support rod 37 lifts the stacked coins to the packaging position and stops, the cam 18B of the cam shaft 43 (not shown)
The packaging roller (10) approaches the packaging rollers (11, 12) whose positions are fixed via the arms (57, 57) and clamps the stacked coins. On the other hand, the wrapping rollers 10, 11 and 12 are all forcibly rotated as described above, and the stacked coins are also rotated. On the other hand, the paper feed motor is rotated at a predetermined time, and as a result, the wrapping paper feeding rolls 67 and 68 are rotated to feed the wrapping paper 65 and the leading end of the wrapping paper 65 stopped at the position of the cutter 70 is wrapped. The wrapping paper wound around the stacked coins is wound between the rollers 10 and 11, and the wrapping paper wrapped around the stacked coins is pulled and pressed against the cutter 70 to be cut. The feeding rolls 67 and 68 are
Immediately thereafter, it is stopped by stopping the paper feed motor. During the winding of the wrapping paper 65 around the surface of the stacked coins, the cam shaft
By a group of cams (not shown) 43, the caulking claws 71, 71 are moved in the radial direction of the stacked coin to be positioned above and below the stacked coin, and from that position, they are vertically moved close to each other, and both caulking claws 71 are , 71 is wound around the upper and lower end surfaces of the stacked coin and the upper and lower ends of the wrapping paper are crimped.

On the other hand, the lower support rod 37 is lowered to a fixed position by the cam 44 while the upper and lower ends of the wrapping paper are being crimped by the crimping claws 71, 71, and then the moving base 27 is rotated by the motor M ₁ of the moving mechanism 34 to rotate the crank arm 35 and the link 36. Via the chute 56 as shown in FIGS. 3 and 10 and moved away from the end of the coin passage 15.
Is opened immediately below the packaging unit 25. And caulking claws 71,71
After the caulking operation of the upper and lower ends of the wrapping paper 65 by the above is completed and the retreating of the caulking claws 71, 71 is completed, the packaging roller 10 is retracted by the cam surface K of the cam 18B, the holding of the packaging coin is released, and The coins are stored in the packaging coin box 5 through the chute 56. Immediately after the wrapping roller 10 moves toward the wrapping rollers 11 and 12 side by the cam surface J of the cam 18, the cam shaft 43 makes one rotation and returns to the fixed position, and one wrapping cycle is completed. Then, the movable table 27 is returned to the position shown in FIGS. 1 and 9 again, and when the sensor S ₃ ′ detects it, the counting and multiplying operation is restarted, and thereafter, the same operation is repeated to perform the packaging.
As shown in FIGS. 5 (A) to 5 (C), the link 36 pushes the lever 52 when the movable base 27 moves from the retracted position to the advanced position, and the lever 52 swings through the thought spring 54. The pressing roller 53 is moved and rests on the coin feeding member 24.

Note that the wrapping paper 65 used for wrapping is commonly used for a plurality of denominations and wraps coins having different stacked coin heights. Therefore, as shown in FIG. 15 (M), the height position of the lower surface of the stacked coins (the upper surface of the lower support bar 37) is set to the gold level with respect to the lower edge of the wrapping paper 65 positioned at a constant height position on the machine base 8. The type of stacking coins is changed according to the height. In other words, the stacking coin (height shown in FIG.
In case of H ₁ ), the ascending height of the lower support rod 37 should be small and the machine base 8
The upper position is raised by a distance L _1, and in the case of stacking coins (height H ₂ ) where the stacking coin height is small, the bottom support bar
The ascending height of 37 is large, and the distance L _{2 is} raised above the machine base 8. This change in the amount of lifting of the lower support rod 37 is caused by the above-mentioned cam.
This is done by restricting the rise of the arm 40 by the cam surface 47A of 47. Therefore, the cam surface 47A is an uneven cam surface according to the height of the stacked coins of each denomination.

The change in the amount of rise of the lower support rod 37 is changed according to the denomination, but the stacking coin height is divided into three groups, high, middle, and low, and the lower support rod 37 is placed at a predetermined position for each group.
May be located.

In FIG. 11 and FIGS. 15 (A) to (M) corresponding thereto, in the case of stacking of large-diameter coins, the leading edge of the coin hits the contact portion 24A of the coin feeding member 24. When the coin is fed, the rear end of the coin is not yet separated from the pulley 23, and the coin feeding member 24 is rotated while the conveying force of the belt 21 is applied to the coin. The wrapping roller 11 approaches to the coin, and as shown in FIGS. 16 (A) to 16 (E), the coin is fed at its leading edge by the inertial force applied to the coin when the rear end of the coin is ejected from under the pulley 23. Stacking is performed as the member 24 is rotated.

When packaging large-sized coins, as shown in Fig. 12, and when packaging small-sized coins, as shown in Fig. 14, the packaging roller 10 moves to press and stack the stacked coins against the packaging rollers 11, 12. Packaging is done.

Figures 17 and 18 show the wrapping section, and Figure 17 shows the stacking of coins of the smallest diameter (note that this corresponds to Figure 13, but Figure 13 shows the height range of the coin passage 15). On the other hand, FIG. 17 shows the height range in which the packaging rollers 10, 11 and 12 are provided.)
FIG. 18 shows a state in which the coin stacking space forming member is moved in the radial direction when a stacking failure occurs. At the time of stacking in FIG. 17, the wrapping roller 11 has the cam surface A'of the cam 18A.
Is placed at the stacking position corresponding to the minimum coin diameter.
Further, since the paper guide plate 59A fixed to the arm 57 is at a fixed position in the adjustment movement of the packaging roller 11, the paper guide plate 61 is positioned at a position corresponding to the coin diameter through the follower 61a that abuts against it. A follower 63B is moved through an arm 58A fixed to 58, and the arm 63A is adjusted and moved around the axis of the packaging roller 12.

In this state, the coin counting and stacking operation is performed by the rotation of the motors M ₂ and M ₃ , but when the stacking abnormality detection signal from the abnormality detection unit 101 is input to the control unit 100, the motor of the cam shaft 4 is driven. When Mc rotates, as shown in FIG. 18, the cam surfaces G and G'for maximum opening of the cams 18 and 18A come to the positions corresponding to the rollers 19B and 11B, the passage width takes the maximum opening position, and coin stacking occurs. The wrapping roller 11 and the paper guide plate 61 as the space forming member are most retracted, and the paper guide plate 63 is also moved in the radial direction, so that the wrapping rollers 10, 11, 12 and the movable paper guide plate 59A are moved as shown in the eighteenth illustration. , Paper guide plates 59B, 61, 63, coin feeding member 2
4, the coin stuck between the guide plates 62A and 62B, the abutting plate 60, and the guide member 64 is released, and then the motor M ₁ rotates to move the 19th coin.
As shown in the figure, the moving table 27 moves out, the stacked coins are discharged, and the defective stacking of coins is eliminated.

In addition, even when the moving base 27 moves out, the motor M ₄
19 As the coin feeding member 24 is rotated as shown in the figure, the stacking coins can be removed by moving the moving table 27 without causing coin jams.

Although the coin feeding member 24 in the above embodiment is shown as a case having a ratchet wheel structure formed by an integrally molded product,
This has a belt structure as schematically shown in FIG. 21. Coin tip edge contacting portions 24A, 24A ... Are provided on the peripheral surface of the belt 72 at regular intervals, and a leading portion is provided between these contacting portions. The adjacent inclined portions may be used as coin rear end edge displacement portions 24B, 24B ...

Further, in the above embodiment, the case where the coin feeding member 24 is structured to be supported by the horizontal shaft has been described.
As shown in the figure, the structure is such that it rotates in a horizontal plane, and one side of the claw portions 24C, 24C, which are provided to project in the radial direction, is a contact portion 24A, and the upper surface extending to the other side is a displacement portion 24B. It is also possible to stack them sequentially.

Other than that, the following embodiments can be considered for each part.

The coin transfer means may be a belt 21 or a roller, and the coin passage 15 is not limited to a horizontal passage and may be an inclined coin passage. Further, the coin passage is not limited to a straight coin passage, and may be a coin passage bent in the middle.

In the illustrated embodiment, the coin stacking space portion 9 is provided in the end area of the coin passage 15, but it is located outside the coin passage and its entrance is faced to the end of the coin passage 15. You can also Further, since the coin stacking space portion 9 is partially shared with the coin wrapping portion, a packaging roller or the like is used as a coin stacking space forming member, but when it is desired to share it with the coin wrapping portion, a dedicated coin stacking portion is used. A product space forming member may be used.

Further, the coin feeding member 24 is configured to be rotated by the coin itself, and for example, the coin feeding member 24 is forcedly rotated by the motor only for the 50th coin,
Not limited to this, in order to ensure smooth rotation of the coin feeding member 24, it is possible to consider forcibly rotating the coin when the flow of the coin is stagnant. Although the counting sensors are used as the sensors S ₁ and S ₂ constituting the detecting means in the present invention, a dedicated detecting sensor other than the counting sensor may be provided.

[Effect of device]

As described above, according to the present invention, since coins are piled up by the coin feeding member, the entrance of the coins into the coin aligning cylinder is electrically detected and the receiving plate is lowered as in the conventional case. If the feeding speed of coins is increased as in the case of electrically controlling the coins, the responsiveness does not deteriorate, and the coins do not collapse easily and can be piled up in an orderly manner. There is an excellent effect that can be eliminated.
