BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin wrapping machine, and in particular, it guides an inserted coin into a coin passage to sort coins of a preset denomination, and then counts the sorted coins. A predetermined number of accumulated coins are accumulated in the accumulating unit, the accumulated predetermined number of accumulated coins are guided to the wrapping unit, and the wrapping paper is wound around the accumulated coins by the operation of the wrapping mechanism, and The present invention relates to a coin wrapping machine that forms a wrapping coin by swaging an end portion with a swaging claw.

[0002]

2. Description of the Related Art Conventionally, as this type of coin wrapping machine, one disclosed in Japanese Patent Laid-Open No. 3-612 is known. In the coin packaging machine shown in this publication, the packaging mechanism is
A crimping claw for crimping the upper and lower ends of the wrapping paper wound around the accumulated coins, an upper arm with an upper crimping claw inside the crimping claw attached, and an upper swing for vertically moving the upper arm. A moving arm, an upper crimping cam (first cam) for swinging the upper swinging arm, a lower arm to which a lower crimping claw of the crimping claws is attached, and the lower arm moving vertically A lower swing arm, a lower swaging cam (second cam) that swings the lower swing arm, and two pulleys supported between the upper arm and the lower arm,
A common spring for urging the upper arm downward and the lower arm upward is provided.

Explaining this packaging mechanism in a little more detail, the upper arm having the upper crimping claw attached thereto is supported so as to be placed on the roller at the swinging tip of the upper swinging arm, while the upper swinging is carried out. The arm is configured so that the cam follower attached to the intermediate position thereof abuts on the upper cam surface of the upper crimping cam. As a result, when the cam surface of the upper crimping cam is lowered, the upper swinging arm is swung downward, and as a result, the upper arm is lowered, and the upper crimping claw is placed at the upper end of the wrapping paper wrapped around the accumulated coins. It comes in contact with the part. Then, when the cam surface of the upper crimping cam further lowers, the upper crimping claw continues to descend by the urging force of the spring until it comes into contact with the upper surface of the accumulated coins and the lowering movement is restricted, whereby the wrapping paper is The upper end of is to be crimped by the upper crimping claw.

At this time, since the upper arm is only in contact with and supported on the swing tip of the upper swing arm,
While the lowering is restricted together with the upper caulking claw, the upper swing arm continues to further descend due to its own weight according to the cam surface of the caulking cam.

Further, the lower arm to which the lower crimping claw is attached is urged upward by the urging force of a common spring so as to come in contact with the lower end of the oscillating tip of the lower oscillating arm below the roller, and the lower oscillating arm is moved. The arm is configured so that the cam follower at the intermediate position thereof abuts the lower cam surface of the lower crimping cam. As a result, when the cam surface of the lower crimping cam rises, the lower swing arm can swing upward, and as a result, the lower arm is raised by the urging force of the shared spring, and the lower crimping claws accumulate coins. It is designed to come into contact with the lower end of the wrapping paper wrapped around. Then, when the cam surface of the lower crimping cam further rises, the lower crimping claw continues to ascend by the biasing force of the common spring until it comes into contact with the lower surface of the accumulated coins and the upward movement is restricted. The lower end of the paper will be crimped by the lower crimping claw.

At this time, when the lower arm is restrained from rising, the lower swing arm is in contact with the upper surface of the lower arm regardless of the urging force of the spring to raise the lower swing arm. The ascending movement can be stopped with. As a result, the cam follower of the lower swing arm and the lower crimp cam do not come into contact with each other.

[0007]

By the way, in the coin wrapping machine having the wrapping mechanism configured as described above, the upper spring is provided with the upper spring and the lower spring is provided with the upper crimp claw. It is necessary to generate a force that urges downward and a force that urges the lower crimp claw upward,
A load such as the weight of the lower arm to which the lower caulking claw is attached and the weight of the lower swing arm with which the roller at the swing tip contacts the upper surface of the lower arm is applied.
That is, the shared spring needs to generate an urging force that only applies these forces.

Further, in such a packaging mechanism, the distance between the upper crimping claw and the lower crimping claw is measured to detect the excess or deficiency of the packed coins that have been packaged. The rack was equipped with a pinion meshing with the rack and a rotary encoder connected to the pinion on the other side. For this reason, the shared spring that is stretched between the upper arm and the lower arm is further loaded, and the mechanism around the upper arm and the lower arm is complicated. Further, since the rotary encoder is supported by an upper arm or a lower arm that moves up and down and left and right, it is necessary to consider the arrangement and durability of signal lines for transmitting signals from this to the control unit.

The present invention has been made in view of the above circumstances, and reduces the load applied to the spring for urging the upper arm or the lower arm and simplifies the mechanism around the upper arm and the lower arm. It is an object of the present invention to provide a coin wrapping machine which is capable of achieving high durability and is excellent in durability.

[0010]

In order to achieve the above object, the invention according to claim 1 is to select and count the denominations of a plurality of inserted coins, and then stack them vertically in a stacking unit. A coin is formed by forming a stack of coins consisting of a predetermined number of coins, wrapping the wrapping paper around the circumference of the stacking coin in the packaging unit, and crimping the upper and lower ends of the wrapping paper with a pair of upper and lower crimping claws. In a coin wrapping machine, an upper arm and a lower arm, each of which has a pair of upper and lower crimping claws attached to its tip, are arranged to be linearly movable in the vertical direction, and an upper swing arm arranged to be swingable in a vertical plane. And a lower swinging arm, and a first connecting means for connecting the upper arm and the upper swinging arm and moving the upper arm up and down by constantly interlocking with the swinging motion of the upper swinging arm. Second connecting means for connecting the lower arm and the lower swing arm and moving the lower arm up and down by constantly interlocking with the swing motion of the lower swing arm; the upper swing arm and the lower section; Any one of the upper swing arm and the lower swing arm, which is connected to a swing arm, and which is always linked so that the upper swing arm and the lower swing arm swing in opposite directions. One of the upper arm, the lower arm, the upper swing arm, and the lower swing arm is attached to the drive means for swinging one side in the vertical direction, and the upper arm is moved downward or the lower arm. It proposes a coin wrapping machine including an urging means for urging the coin upward.

According to a second aspect of the invention, in the coin packaging machine, a swing amount detecting means for detecting a swing amount of either the upper swing arm or the lower swing arm,
An excess / insufficiency determination means for determining excess or deficiency of the number of coins included in the packaged coin based on the detection signal from the swing amount detection means, and the excess or deficiency determination means determines that the coin has excess or deficiency. In this case, a coin wrapping machine having at least an alarm means for issuing an alarm is proposed.

According to a third aspect of the present invention, the drive means includes a pulse motor driven by a drive pulse,
The swivel amount detection means comprises a swaging claw cam that is driven to rotate by the pulse motor and has a cam surface that follows a cam follower provided on either the upper swing arm or the lower swing arm. An initial position setting means for setting the initial position of the caulking claw cam by associating the rotation angle of the caulking claw cam with the drive pulse to the pulse motor at the time when the maximum swing amount or the minimum swing amount is detected. We propose a coin packaging machine equipped with it.

Further, the invention according to claim 4 proposes a coin wrapping machine provided with a wrapping position adjusting means for adjusting the height position of the accumulated coins to be packed in the wrapping section according to the denomination of the coins. ing.

[0014]

According to the coin wrapping machine of the first aspect of the present invention, the coins that have been inserted are counted after the denominations have been sorted out and stacked in the stacking unit to form stacked coins. The formed coins are sent to the wrapping unit, the wrapping paper is wrapped around the wrapping unit, and the upper and lower ends of the wrapping paper are crimped to form the wrapping coin.

In this case, the upper arm and the lower arm to which the crimping claws for crimping the upper and lower ends of the wrapping paper are attached to the upper swing arm and the lower swing arm via the first and second connecting means. , And the upper swing arm and the lower swing arm are linked by link means so that they are always linked, so that when the drive means is actuated, As a result of either the upper swing arm or the lower swing arm to which the means is attached being moved up and down, the other swing arm is moved up and down in the opposite direction in conjunction with this.

When the work of crimping the wrapping paper by the crimping claws is started, both the crimping claws receive a force such that they are pushed back from the upper and lower end surfaces of the wrapping paper or the accumulated coins with which they are in contact. However, due to the operation of the urging means, the wrapping paper is crimped by the urging force received from the urging means. Here, the upper arm, the lower arm, the upper swing arm and the lower swing arm are connected by the first and second connecting means and the link arm so as to be always interlocked, and the upper arm and the upper swing arm are connected. Since the lower arm and the lower swing arm are always moved in opposite directions, the rotational moment applied to the upper swing arm cancels out the rotational moment applied to the lower swing arm. . Therefore, the urging means only needs to have a urging force for crimping the upper and lower ends of the wrapping paper wound around the accumulated coins.

According to the coin wrapping machine of the second aspect of the invention, the swing amount detecting means only detects the swing amount of either the upper swing arm or the lower swing arm.
The excess / deficiency determination means determines whether the number of coins in the packaged coins is excessive or insufficient by the upper crimping claw and the lower crimping claw, and the alarm means issues an alarm. it can. In this case, it is not necessary to mount the excess / deficiency detection means on the upper arm and the lower arm that move up and down, so that the load applied to the spring that biases the upper swing arm or the lower swing arm is reduced. Is possible.

Further, according to the coin wrapping machine of the third aspect of the present invention, by providing the drive pulse, the pulse motor is driven and the caulking claw cam is rotationally driven by an angle corresponding to the drive pulse. As a result, the cam follower provided on either the upper swing arm or the lower swing arm is driven by the cam surface of the caulking claw cam,
One of the swing arms provided with the cam follower is driven to swing up and down, and in conjunction with this, the other swing arm and the upper and lower arms are moved up and down. On the other hand, the swing amount detecting means provided on the upper swing arm or the lower swing arm detects the swing amount of the swing arm.

In this case, when the initial position setting means is actuated, at the time when the swing amount detected by the swing amount detecting means becomes maximum or minimum, the rotation angle of the caulking claw cam at that time and the drive to the pulse motor. And pulse. That is, the maximum amount of swing detected by the swing amount detecting means is when the cam follower on the cam surface of the caulking claw cam is arranged at the lowest position, and when the swing amount is minimum. , When the cam follower is located at the highest position. Further, the number of drive pulses of the pulse motor required to rotate the caulking claw cam from the initial position to the lowest position or the highest position of the cam surface is known. Therefore, the rocking amount detecting means sets the known driving pulse number at the time when the rocking amount becomes maximum or minimum, whereby the initial position of the caulking claw cam is set.

Further, according to the coin wrapping machine of the fourth aspect of the present invention, the height position of the accumulated coins at the time of wrapping is adjusted by the operation of the wrapping position adjusting means according to the denomination of the coins. When the upper and lower ends of the wrapping paper wrapped around the accumulated coins by the upper and lower crimp claws, the accumulated coins can be swaged without being displaced. As a result, it is possible to prevent the coins forming the accumulated coins from tilting during packaging, and it is possible to obtain an appropriate packaged coin.

It is adapted to be rotationally driven by a cam motor 87 (see FIG. 7) including a motor.

Next, the shapes of these various cams will be described with reference to the cam diagram of FIG. In the figure, 0
The position indicated by ° is the cam shaft 46 to which various cams are fixed.
It indicates the initial position of.

In the post cam 26, the support post 15 reaches the highest point within the range of about 50 to 70 ° of the cam shaft 46 from the initial position and receives the accumulated coins 7 from the accumulating section 4. Further, in the range of about 120 to 270 degrees of the cam shaft 46, the support post 15 remains in the packaging position in the packaging unit 12, and the packaging operation is performed during this period. Also, the cam shaft 46
In the range of about 300 to 330 °, the post cam 26
By moving the support post 15 to the lowest point, the support post 15 is separated from the lower surface of the wrapped packaging coin. In the meantime, the packaging coins can be discharged downward from the packaging section 12 by retracting the support posts in the horizontal direction by the operation of the post relief cam described later.

The post relief cam is formed by the support post 15
While the accumulated coins 7 are being supported by the stacking coins 3 within the range of about 30 to 310 ° of the cam shaft 46 so as not to move the horizontal support position thereof, the packaging rollers 3 directly below the accumulated coins 3 or the three packaging rollers 3 are provided.
It is formed so as to be set at the central position of 6, 37, 38. In addition, about 310 mm across the initial position of the cam shaft 46

It is in a position retracted horizontally between 6, 37 and 38,
It is formed so that it can be moved up and down without performing a packaging operation.

This prevents the cam shaft 46 from vibrating due to the backlash of the drive system while the integrated coins 7 are being guided to the packaging portion 12 by the support posts 15 due to the load applied to the entire cam shaft 46. This is to prevent the accumulated coins 7 from collapsing due to this vibration.
In addition, during this operation, the cam shaft 46 can be detected in its initial position, as will be described later, at a position of about 120 ° of the cam shaft 46 in the radial direction of the cam surface 64a of the caulking claw cam 64. The lowest point a having the smallest dimension is formed.

In the cam profile B formed in the range of about 180 to 330 ° of the cam shaft 46, the caulking claw cam 64 has three upper and lower caulking claws 54 and 55 for the packaging rollers 36, 37, and 37. It is arranged between 38 and is configured to be moved up and down in order to perform an actual packaging operation. In the other angle range of the cam shaft 46, the caulking claw cam 6
4, the upper and lower caulking claws 54 and 55 are moved most apart to move between a position arranged between the packaging rollers 36, 37 and 38 and a position retracted from between the packaging rollers 36, 37 and 38. Is formed so that it can be.

The caulking claw escape cam 77 is located above and below the caulking claw 5 within the range of about 170 to 330 ° of the cam shaft 46 during the period in which the upper and lower caulking claws 54 and 55 perform the packaging operation.
4, 55 are formed so as to be positioned between the packaging rollers 36, 37, 38, and in other ranges, the upper and lower crimping claws 54, 55 are horizontally retracted from between the packaging rollers 36, 37, 38. It is formed to let.

Next, regarding the operation of the control device 14,
This will be described with reference to the control block diagram of FIG. Control device 1
4 is a counting motor 81, a counting sensor 82, a stopper 8
3, counting unit mechanism 86 including integrated motor 84 and shutter solenoid 85, cam motor 87, rotary encoder 75, packaging motor 88, packaging paper supply motor 8
9. A packaging unit mechanism 92 including a packaging position adjusting motor 90 and an alarm means 91, a ROM 93 in which reference data such as the diameter and thickness of the coin type of the coins to be handled, an operation program of the entire coin packaging machine, and the like are stored. Coin denomination data set for packaging processing, coin counting data,
A RAM 94 for sequentially storing various data such as accumulated number of pieces of data and operating states of various motors, an operation unit 95 for setting a denomination of coins to be packed, a display for displaying count data of the packed coins, etc. The unit 96 and the CPU 97 that comprehensively controls these units.

The counting motor 81 drives the rotating disc 1 and the conveyor belt 3 in the coin passage 2. The counting sensor 82 is a sensor provided in the coin passage 2 for detecting the number of coins of a set denomination, and further includes a material sensor or the like to configure a coin discriminating unit. Is also good. In the stopper 83, when the number of coins counted by the counting sensor 82 is the packaging unit number (usually 5
When the number of coins reaches 0, it prevents the subsequent coins from passing. The stacking motor 84 rotates the stacking drum 6 of the stacking unit 4 in association with the detection of coins by the counting sensor 82 to stack the coins. The shutter solenoid 85 is for opening and closing the shutter 8 provided directly below the stacking unit 4.

The cam motor 87, as described above,
A motor that drives the cam shaft 46, and is composed of a pulse motor. The wrapping motor 88 is a motor that drives the two fixed wrapping rollers 36 and 37, and rotates at a low speed when the wrapping paper 9 is wound around the accumulated coin 7, and the wrapping paper 9 is rotated around the accumulated coin 7 once or more. After being wrapped, it can be rotated at high speed. The wrapping paper supply motor 89
Is driven so as to wind the wrapping paper 9 around the accumulated coins 7 by about two rotations. The wrapping position adjusting motor 90 adjusts the height position of the post arm 19 at the wrapping position according to the denomination signal of coins to be wrapped. The alarm means 91 is a rotary encoder 7.
As a result of detecting whether there is an excess or deficiency of the number of stacked sheets by 5, the alarm is issued, the operation of each motor is stopped, or a visual alarm is displayed. is there.

In the control device 14, the initial position setting means for setting the initial position of the cam shaft 46 according to the measurement result from the rotary encoder 75 and the integrated coin 7.
An excess / deficiency determining means for determining excess / deficiency of the accumulated number of sheets is incorporated.

The operation of the coin wrapping machine according to this embodiment having the above structure will be described below. First, when the coin wrapping machine is turned on, the coin wrapping machine initializes the entire device. In this initializing operation, the initial position setting work of the cam shaft 46 is performed by the operation of the initial position setting means incorporated in the control device 14.

That is, an appropriate drive pulse is provided from the control device 14 to the cam motor 87 which is a pulse motor, and the cam motor 87 rotationally drives the caulking claw cam 64 and the like. In this case, when the caulking claw cam 64 is rotated, the upper swing arm 58 having the cam follower 65 in contact with the cam surface 64a is swung up and down. The upper swing arm 58 is provided with a spring 66 that biases the cam follower 65 in close contact with the cam surface 64 a of the swaging claw cam 64. The first connecting member 6 is attached to the tip end of the first connecting member 6 while faithfully following the cam profile of the cam surface 64a.
The upper arm 56 connected through 0, and further,
The caulking claw 54 fixed to the tip end is moved in the vertical direction.

On the other hand, since the lower swing arm 59 is connected to the upper swing arm 58 via the link arm 62, the lower swing arm 59 is surely interlocked with the operation of the upper swing arm 58, and thus the upper swing arm 58 is moved. The arm 58 is moved up and down in the opposite direction. Then, the swing angle of the lower swing arm 59 is detected by the rotary encoder 75 via the rack gear 73 attached to the rear end of the lower swing arm 59 and the pinion gear 74 meshing with the rack gear 73.

In this case, the caulking claw cam 64 includes
Upper and lower crimping claws 54, 55 at a position 120 ° from the initial position
Since the lowest point a that is closest to is provided, the initial position is calculated backward by detecting the lowest point a. That is, the position where the measured value of the rotary encoder 75 becomes maximum or minimum is when the cam follower 65 of the upper swing arm 58 reaches the lowest point a of the caulking claw cam 64. By associating the drive pulse with the rotation angle of the crimping claw cam 64, that is, setting the rotation angle of the crimping claw cam 64 at this point to be 120 °, the cam motor 87 is left with the remaining 240 °. Minute drive pulse,
The cam shaft 46 can be set to the initial position.

At the end of this initializing operation, the operator presets the denomination of coins to be packed, the number of accumulated coins, etc. by the operation unit 95 prior to the operation of the coin wrapping machine (however, in Japan. For coins, set only the denomination. The data such as the set denomination is displayed on the display unit 96, stored in the RAM 94, and the standard value of the stacking height is calculated based on the thickness dimension data of the coins stored in the ROM 93. It When the denomination and the number of accumulated coins are set, the controller 14 sends a signal to the wrapping position adjusting motor 90 of the wrapping position adjusting mechanism 17 so that the wrapping position of the accumulated coins 7 corresponds to the denomination and the number of accumulated coins. The packaging position adjusting mechanism 17 is set so as to be arranged at the height position.

That is, in the crimping mechanism 11, the upper and lower crimp claws 54, 55 are moved by the same distance to crimp the wrapping paper 9, so that the central position of the accumulated coins 7 in the height direction is always maintained. It is necessary to set them at positions equidistant from the upper and lower crimp claws 54 and 55. However, the stacking height varies depending on the number of stacked sheets and denominations having different thicknesses.

In such a case, when the height position of the support post 15 during the packaging operation is fixed according to the denomination having the maximum stacking height and the number of stacked sheets, the denomination having the minimum stacking height is provided. When wrapping coins such as the above, the lower crimping claw 55 crimps the lower end portion of the wrapping paper 9 before the upper crimping claw 54 crimps the upper end portion of the wrapping paper 9 and reaches the upper surface of the accumulated coins 7. To reach the lower surface of the stacked coins 7, the stacked coins 7 already wrapped with the wrapping paper 9 are lifted within the wrapped wrapping paper 9, and the horizontally stacked coins are There is the inconvenience of tilting inside. On the other hand, when the height position of the support post 15 during the packaging operation is fixed according to the denomination having the minimum stacking height, when coins of the denomination having the maximum stacking height are packaged. , Lower crimp claw 5
Before the upper end of the wrapping paper 9 reaches the lower surface of the stacking coins 7, the upper swaging claw 54 presses the upper end of the wrapping paper 9 to reach the upper surface of the stacking coins 7. The stacked coins 7 with the paper 9 being wound are pushed down in the wrapped wrapping paper 9, so that the stacked coins 7 are pressed against the support posts 15 that already support the stacked coins 7 and are stacked horizontally. There is an inconvenience that the coins that are tilted in the wrapping paper 9.

For this reason, the operator presets the denomination of coins and the number of accumulated coins before the actual packaging work, and the packaging position of the accumulated coins 7 is set at an appropriate position according to the denomination and the accumulated number of coins. It is supposed to be set to. As a result, the upper and lower crimping claws 54 and 55 can crimp the wrapping paper 9 so that they reach the upper and lower ends of the accumulated coins 7 at the same time.

Next, when coins are put into the rotary disc 1,
Due to the centrifugal force generated by the rotating disc 1, the inserted coins are fed into the coin passage 2 one by one. In the coin passage 2, while being conveyed by the feed belt 3, it is determined whether or not the coin is a coin of a set denomination. As a result, coins other than the set denomination are ejected, and when the coin is the set denomination, the number of coins is counted.

The coins conveyed through the coin passage 2 are successively supplied to the stacking drum 6, and are stacked in a stack by the stacking drum 6 which is rotationally driven in synchronization with this supply. When a predetermined number of coins are accumulated by the accumulating drum 6, the accumulating drum 6 is further rotated and the accumulating coins 7 are placed on the shutter 8 arranged below the accumulating drum 6. On the other hand, when the counting of the predetermined number of coins in the coin passage 2 is completed, the cam motor 87 is driven, the operation of the integrated coin guide mechanism 13 is started, and the operation of the support post moving mechanism 16 causes the support post 15 to move the shutter 8 to the shutter 8. It is placed in the standby position just below.

Further, the accumulated coins 7 are transferred onto the support post 15 by driving the shutter solenoid 85 to open the shutter 8 on condition that the accumulated coins 7 are placed on the shutter 8. Be done. Then, the accumulated coins 7 are conveyed to the wrapping unit 12 by the operation of the accumulated coin guide mechanism 13 to lower the supporting posts 15, and the wrapping rollers 36, 37, which are set by the operation of the wrapping position adjusting mechanism 17. It is placed in the packaging position between 38.

At this time, the caulking claws 54, 55 are moved by the operation of the caulking claw escape cam 77 so that the packaging rollers 36, 37,
It is arranged at a position horizontally separated from 38.
In addition, since the caulking claw cam 64 is actuated to move it up and down without actually performing the packaging work, vibrations due to the backlash of the drive system are accumulated while the accumulated coins 7 are being conveyed by the support posts 15. The application to the coins 7 is avoided, and the accumulated coins 7 are stably supported on the support posts 15.

When the accumulated coins 7 are placed at the wrapping position, the roller opening / closing cam 47 presses the wrapping roller 38 via the cam follower 45, the first and second actuating plates 43, 44 and the swing lever 40. Two fixed packaging rollers 3
The coins 7 are horizontally moved in the directions of 6, 37, and the accumulated coin 7 is sandwiched between these three packaging rollers 36, 37, 38. At this time, the stacked coins 7 are sandwiched between the packaging rollers 36, 37, 38, and at the same time, the swing lever 40 for supporting the pressing and packaging roller 38 and the first operating plate 43 connected thereto.
The horizontal swinging motion of is restricted. The horizontal swinging motion of the second operating plate 44 is further continued according to the unevenness of the cam surface 47a of the roller opening / closing cam 47.
The difference between the horizontal swing amounts of 3 and 44 is absorbed by the compression spring 48.

That is, the compression spring 48 at this time
The elastic force of the pressing wrapping roller 38 fixes the wrapping roller 3
The pressing force is applied to 6, 37. Therefore,
When the wrapping operation is not performed, the spring 4 that separates the pressing wrapping roller 38 from the fixed wrapping rollers 36 and 37.
In No. 9, the elastic force is small, and the load applied to the cam shaft 46 is also small.

After this, the controller 14 outputs an operation command to the wrapping paper supply motor 89 and the wrapping motor 88 which drive the wrapping paper supply roller 80. As a result, the wrapping paper 9
Is supplied between the wrapping rollers 36, 37, 38 and the accumulated coins 7 and is wound around the cylindrical surface of the accumulated coins 7 by the rotation of the wrapping rollers 36, 37, 38.

Further, the rotation of the cam motor 87 activates the caulking claw escape cam 77, and the lower swing arm 53 swings the upper and lower caulking claws 54 and 55 to the positions where they are arranged above and below the stacking coin 7, respectively. To be Then, by the operation of the caulking claw cam 64, the upper swing arm 58 is swung downward to lower the upper arm 56, and the lower swing arm 59 connected by the link arm 62 is swung upward. Then, the lower arm 57 is raised.

In this case, the upper swing arm 58
Is constantly urged downward by the spring 66, the cam follower 65 attached to the upper swing arm 58 follows the shape of the cam surface 64a of the caulking claw cam 64 faithfully following the shape of the upper swing arm. 58 is moved up and down. On the other hand, since the lower swing arm 59 is also connected to the upper swing arm 58 via the link arm 62, the lower swing arm 59 is always interlocked with the vertical movement of the upper swing arm 58, and thus the upper swing arm 5 is moved.
8 is moved up and down in the opposite direction.

Here, the weight of the upper arm 56 is applied to the upper swing arm 58 in addition to its own weight, while the own weight and the weight of the lower arm 57 are applied to the lower swing arm 59. However, since the swing arms 58 and 59 are connected via the link arm 62, most of the rotational moment due to the weight of the structural member applied to the swing arms 58 and 59 is offset. And then
The spring 6 urging the upper swing arm 58 downward.
It will be avoided that an excessive load is applied to 6.

Therefore, the spring 66 has the caulking claw 5
When the upper and lower ends of the wrapping paper 9 are crimped by the wrapping paper 9, the upper and lower crimping claws 54, 55 resist the force received from the wrapping paper 9, and these crimping claws 54, 55 are attached to the end surface of the coin stack 7. It suffices to generate an urging force for moving the coin toward the head, and compared with the conventional coin wrapping machine in which the spring 66 also receives the weight of the structural member, it can be used more durable. .

In this way, the packing coins are completed by crimping the wrapping paper 9 at the upper and lower ends of the stacking coins 7 by bringing the upper and lower crimping claws 54 and 55 close to each other in the vertical direction of the stacking coins 7. Become. In this case, when the caulking claws 54 and 55 come into contact with the upper and lower end surfaces of the coin stack 7, the vertical movement thereof is further restricted and the biasing force of the spring 66 holds the caulking claws 54 and 55 at that position.

At this time, the swing motions of the upper and lower swing arms 58 and 59 are also stopped, and the measured value of the rotary encoder 75 connected to the lower swing arm 59 is also kept constant. become. Then, the excess / deficiency discriminating means incorporated in the control device 14 compares the measured value with the standard value of the accumulated coins 7 in the accumulated number of the denominations, which has been calculated in advance, and is packaged. Determine whether there is an excess or deficiency in the number of packaging coins,
If there is an excess or deficiency, the alarm means 91 will be activated.

Further, according to the coin wrapping machine of this embodiment, the operation of the wrapping position adjusting mechanism 17 causes the accumulated coins 7
The packaging position is adjusted so that the center position in the height direction of the coin is equidistant from both the crimping claws 54 and 55, and both the crimping claws 54 and 55 are close to the end surface of the coin 7 at the same speed. Since it is configured so that both caulking claws 54, 55
Are brought into contact with the upper and lower end surfaces of the coins 7 at the same time. Therefore, the accumulated coins 7 are not moved in the vertical direction in the wrapping paper 9, and the packaging work is performed while the horizontal accumulated state is maintained.

After that, the swaging claw cam 64 is actuated to open the swaging claws 54 and 55 in the vertical direction, and the swaging claw escape cam 77 is actuated to move the swaging claws 54 and 55 to the packaging rollers 36, 37 ,. The support post 15 is horizontally retracted from below the packaging coin by the operation of the post cam and the post relief cam. And the roller opening / closing cam 4
By the operation of 7, the pressing and wrapping roller 38, which holds the wrapping coin, is horizontally separated from the fixed wrapping rollers 36 and 37, so that the wrapping coin is arranged below the roll chute (not shown). To release.

If it is determined based on the measurement result of the rotary encoder 75 that there is an excess or deficiency in the number of stacked sheets, a reject box (not shown) different from the roll chute is switched by switching a gate (not shown). In addition, excess and deficient packaging coins will be released.

In the present embodiment, the caulking claw 5
Biasing force when the wrapping paper 9 is crimped by 4, 55
The springs 66 provided to 4, 55 are provided on the upper swing arm 58, but instead of this, the springs 66 are used for the upper arm 56, the lower arm 57, or the lower swing arm 5.
9 may be provided. Further, in this embodiment,
The rack gear 73 is attached to the rear end of the lower swing arm 59, and the rotary encoder 75 is arranged via the pinion gear 74 meshing with the rack gear 73. Instead, the swing encoder 73 swingably supports the upper swing arm 58. The moving shaft 78 may be the input shaft of the rotary encoder 75.

Furthermore, in the present embodiment, the predetermined number of coins accumulated by the accumulating drum 6 are once placed on the shutter 8 and then passed on the support post 15. And a predetermined number of coins are accumulated by the accumulation drum 6, the cam motor 87
Is driven to further rotate the accumulating drum 6 at the timing when the supporting post 15 reaches the standby position directly below the accumulating drum 6, so that the accumulating coins 7 of the accumulating drum 6 are directly received on the supporting post 15. You may hand it over.

[0084]

As described above in detail, according to the coin wrapping machine of the present invention, the upper arm and the lower arm to which the crimping claws for crimping the wrapping paper are attached, and these arms are always moved up and down in opposite directions. Since the upper swing arm and the lower swing arm to be moved are connected by the first and second connecting means and the link means so as to be always interlocked with each other, the drive means for driving them and the attachment at the time of caulking work. It suffices to provide only one urging means for generating power. As a result, it is possible to simplify the mechanism, maintainability, reduce the size of the mechanism by saving space, and reduce the number of parts.

Further, since the upper swing arm and the lower swing arm which are interlocked in this way are always swung in the opposite directions, most of the rotational moment applied to these swing arms is offset. Therefore, the load applied to the biasing means can be reduced only to the biasing force required for the crimping work. As a result, there is an effect that the durability of the biasing means can be improved and the size and weight can be reduced.

According to the coin packaging machine of the present invention,
Since the upper swing arm and the lower swing arm are interlocked with each other, one of the swing amounts is detected by the swing amount detecting means, and the number of coins included in the packaged coin is exceeded based on the detection signal. The shortage can be determined by the excess / deficiency determining means. Then, when it is determined that there is an excess or deficiency of coins, at least an alarm is issued by the alarm means, so that the excess or deficiency of the packaging coins can be distinguished and excluded from the regular number of coins.

Further, according to the coin wrapping machine of the present invention, the driving means is composed of the pulse motor and the caulking claw cam, and the swing amount detecting means causes the maximum swing amount or the minimum swing amount by the operation of the initial position setting means. The initial position of the caulking claw cam can be set by associating the rotation angle of the caulking claw cam with the drive pulse to the pulse motor when the swing amount is detected. With this, the initial position of the caulking claw cam can be set without providing a special detection sensor, so that the mechanism can be further simplified.

According to the coin wrapping machine of the present invention,
Since the height position of the stacked coins to be packed in the packing unit is adjusted according to the denomination of the coins by the operation of the packing position adjusting means, the upper and lower crimping claws simultaneously contact the upper end face of the stacked coins during packing. Can be contacted. As a result, it is possible to prevent the accumulated coins from tilting inside the wrapping paper and to produce an appropriate packaged coin.
