Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coin wrapping machine, and particularly to a coin wrapping machine in which the wrapping paper is wrapped around stacked coins in a wrapping section where the wrapping paper is wrapped around stacked coins. The present invention relates to a method for releasing wrapping paper from being caught in the wrapping paper.

[Prior art and its problems]

In conventional coin packaging machines, a plurality of packaging rollers, at least one of which is a movable packaging roller and at least one of which is a driven rotary packaging roller, are provided between the packaging rollers. The wrapping unit has a wrapping section equipped with a paper guide, and the plurality of wrapping rollers pinch and rotate the stacked coins, and at a predetermined time before and after the pinching, the tip of the wrapping paper is connected between the stacked coins and the wrapping rollers. A device is generally used that has a structure in which wrapping paper is wound around the circumferential surface of stacked coins through a plurality of wrapping rollers and a paper guide between the wrapping rollers.

However, in such a lever device, when the wrapping paper is fed toward the wrapping section, a guiding defect occurs in which the leading edge of the wrapping paper is guided diagonally upward or diagonally downward, and as a result, the stacked coins are separated by the wrapping roller. When the wrapping paper is wrapped around the circumferential surface, it may be guided in a direction that is inclined to the circumferential direction of the stacked coins, and may enter between the wrapping roller and the paper guide.

In addition, even if the leading edge of the wrapping paper is fed into the wrapping section normally, it will continue to advance through the gap between the circumferential surface of the stacked coins and the paper guide.
The leading edge of the wrapping paper may be curved and deformed at the stage leading to the next wrapping roller.
The leading edge of the wrapping paper is not guided between the wrapping roller and the circumferential surface of the stacked coins, but stays between the circumferential surface of the stacked coins and the paper guide, and the trailing portion of the wrapping paper is also fed into the gap. , a portion of the stagnant wrapping paper gets stuck between the wrapping roller and the paper guide.

In this way, when the wrapping paper enters between the wrapping roller and the paper guide, the wrapping roller pushes the inserted wrapping paper deeper by forced drive or by rotation following the rotation of the stacked coins.
This results in the paper being caught between the wrapping roller and the paper guide.

This occurrence of wrapping paper getting caught applies a braking force to the wrapping roller, and the wrapping roller stops due to the braking force, and slips between it and the circumferential surface of stacked coins that are being rotated by other wrapping rollers. resulting in damage to the wrapping rollers and coins.

Furthermore, if the packaging roller that is stopped by the braking force is a driven rotating packaging roller, seizure may occur in the drive transmission system or the drive motor.

Furthermore, the occurrence of the wrapping paper getting caught deforms the paper guide, and if the gap between the wrapping roller and the paper guide becomes larger due to the deformation, the wrapping paper will be caught more often when wrapping the wrapping paper later.

Therefore, in conventional coin wrapping machines, when wrapping paper gets caught as described above, the operator immediately stops the machine and manually releases the multiple wrapping rollers that pinch the stacked coins. After releasing the unwrapped stacked coins, the stuck wrapping paper is removed.

However, the work of removing the wrapping paper is difficult because the hand must be inserted into the narrow packaging area, and furthermore, the wrapping paper that is caught between the wrapping roller and the paper guide cannot be easily removed. Therefore, the current situation is to manually shake the packaging roller in the forward and reverse directions, and remove the trapped wrapping paper by picking it up with your fingers or by poking it with the tip of a screwdriver or the like.

If you are unable to remove the stuck wrapping paper, you will need to remove the paper guide, remove it, and then reinstall the paper guide. However, if the paper guide is located deep inside the machine, It has drawbacks such as being very difficult to install and remove.

[Purpose of the invention]

In view of this, the present invention aims to eliminate the drawbacks of the conventional coin packaging machine by releasing the jammed wrapping paper by reversing the wrapping roller and eliminating the paper jam. This provides a cancellation method.

[Summary of the invention]

In order to achieve the above object, in the present invention,
It has a wrapping section including a plurality of wrapping rollers, at least one of which is a movable wrapping roller, and a paper guide provided between the wrapping rollers, and the plurality of wrapping rollers pinch and rotate duplicate coins. At the same time, the tip of the wrapping paper is guided between the stacked coins and the wrapping roller at a predetermined time before and after the pinching, so that the wrapping paper passes through the multiple wrapping rollers and the paper guide between the wrapping rollers to wrap the stacked coins. In a coin wrapping machine, the wrapping paper is wound around the circumferential surface of the wrapping paper, and the wrapping paper is driven by the wrapping detection unit signal generated by the wrapping paper biting detection unit in the wrapping unit when it detects an abnormal decrease in rotational speed or stoppage of the wrapping paper. control unit and packaging cycle operating unit to stop normal rotation of all packaging rollers when the wrapping paper is detected to be caught, and to start the packaging cycle in which the wrapping paper was caught at a predetermined time after the detection. The present invention is characterized by a release method in which, when the wrapping cycle is stopped, all the wrapping rollers in the stopped state are driven in the reverse direction to release the wrapping paper from being caught. As a result, the wrapping paper that was caught between the wrapping roller and the paper guide is returned to the wrapping space by rotating the wrapping roller in the opposite direction.
When the leading end of the wrapping paper is released, the grip is released.

[Embodiments of the invention]

The present invention will be described below with reference to embodiments shown in FIGS. 1 to 7.

(Configuration of entire coin packaging machine) Fig. 1 shows an example of a coin packaging machine used to carry out the present invention, and shows a storage hopper section A for storing input coins, and coins sent out from this storage hopper section A. Rotating disk part B that sends out by centrifugal force
, a coin passage section C that aligns and conveys the coins sent out from the rotating disk section B, a coin counting section D provided at the end area within the coin passage section C, and a coin passage section C that counts coins in the coin counting section D. a coin stacking section E that stacks coins sent out from the coin stacking section E; a packaging section F that receives and packages the number of stacked coins stacked in the packaging unit E; and a packaging section F that sends wrapping paper to the packaging section F. It consists of a paper feed section G that supplies paper, and a discharge section H that corrects the posture of the packaged coins dropped from the packaging section F and guides and releases them into a storage box.

The storage hopper section A is composed of a funnel-shaped hopper wall surface 1 that slopes downward, and a coin supply disk 2 facing the lower opening at the lower end of the hopper wall surface 1. The coins that have been accumulated are sent out one by one by the rotation of the disc 2 and fed into the rotating disc part B.

The rotating disk portion B includes a rotating disk 3 that sends out coins by centrifugal force, peripheral wall portions 4, 4, and a coin thickness regulating member 5.
The coins fed onto the rotating disk 3 are moved to the peripheral edge by centrifugal force, and during the movement, the coins are made into a single layer in the coin thickness direction by the coin thickness regulating member 5 and sent to the coin passage section C.

The coin passage section C has a passage width determined by a fixed passage width 6 and a movable passage width member 7.
A sorting slot is formed in the central part of the passage bottom plate on which the members slide on the upper surface, and the sorting shelf member fixed to the lower surface of each member 6, 7 and protruding inward in the width direction of the passage within the sorting slot The sorting slot width is determined.
The passage width and sorting slot width are adjusted to correspond to the diameter of the denomination coin to be processed by moving the movable passage width member 7 in the passage width direction using the passage width cam 8. As a result, the coins sent out from the rotary disk 3 are conveyed in a line through the coin passage section C, and coins having a diameter smaller than that of the denomination coin are removed into the sorting slot. Further, a transfer belt 9 is provided at the upper part of the passage for forcibly conveying coins.

The coin counting section D includes a sensor 10 that counts the number of coins, and a stopper 11 that is activated when counting the number of coins in a packaging unit and locks subsequent coins. The driving of the conveyor belt 9 and rotating disk 3 is temporarily stopped.

The coin stacking section E includes a pair of stacking belts 12, 12.
A coin piling space is formed by a plurality of guide members 13, 13, 13 provided on the sides of both belts 12, 12, and coins fed into this space are transported from the outer surface of the piling belts 12, 12. The coins are stacked on the protruding coin supports 12a, 12a at symmetrical positions, and the stacking operation of the coins is continued by lowering each stacking belt 12, 12 by a certain pitch each time a coin is introduced. The coin stacking section E is further provided with an opening/closing shutter 14 at its lower end, and is arranged in a direction in which the stacking belts 12, 12 are peeled from each other when the packaging unit number of coins is counted by the coin counting section D and fed into the coin stacking section E. After the coin support parts 12a, 12a have received the coins, they are returned to the stacking start position from the opposing outer peripheral surfaces of the stacking belts 12, 12. As a result, the number of stacked coins placed on the coin supports 12a, 12a is placed on the opening/closing shutter 14. This opening/closing shutter 14 is released at a predetermined time after the packaging section F starts the packaging cycle (the rotation of the camshaft 29, which will be described later, starts from a fixed position).
The stacked coins of the packaging unit number are sent to the packaging section F, where the coins are packaged.

(Configuration of Packaging Unit) Next, the packaging unit F to which the present invention is applied will be explained. As shown in FIGS. 1 and 2, three packaging rollers 15, 16, 17 are provided, among which The rollers 15 and 16 are fixed-position wrapping rollers, and the wrapping roller 17 is a movable roller that moves in the coin radial direction to pinch stacked coins.

17. A packaging space 25 is formed by paper guides 18, 19, 20, and 21. Note that the paper guide 19
is formed only in the central region in the axial direction of the wrapping roller 15, and guides the protruding V-shaped tip of the wrapping paper being fed. The reason for this is that the winding hooks 26, 26 are located at the upper and lower positions of the paper guide 19, that is, at the upper and lower positions of the paper guide 19 in the axial direction of the packaging roller 5. . The upper and lower protruding edges of the wrapping paper that is being wrapped around the circumferential surface of the piled coins are tightened, and after the tightening is completed, they move in directions away from each other and then return to the radial side of the space 25. . Further, a stacked coin support rod 28 is provided at the lower side of the space 25, and at a predetermined time after the start of the packaging cycle, it first moves in the radial direction to reach a position directly below the space 25, and then moves upward. It reaches the lower part of the opening/closing shutter 14 of the stacked coin section E. Immediately after that, the opening/closing shutter 14 is opened and the stacked coins are transferred onto the stacked coin support rod 28. The stacked coin support rod 28 is vertically lowered with the stacked coins placed thereon, and the stacked coin support rod 28 is lowered in the vertical direction with the stacked coins placed on top, so that the packaging position of the space 25 (the vertical position of the stacked coins is in the width direction of the wrapping paper fed into the space 25). The support rod 28 is temporarily stopped at a height position corresponding to the position, and immediately after that, the packaging roller 1 is
5, 16, and 17 sandwich the stacked coins, and the rotation of wrapping rollers 15, 16, and 17 gives rotation. This support rod 28 has upper and lower protruding edges of the wrapping paper wrapped around the periphery of stacked coins.
Immediately after the coins are crimped by , 16, 17 are prepared for falling and releasing the wrapped coins when the clamps are released.

A camshaft 29 is provided as a packaging cycle actuator (FIG. 7, 102) for determining one packaging cycle, and one packaging cycle is performed by one rotation of this camshaft 29 from a normal position. The cam shaft 29 includes a cam 30 for moving the packaging roller 17, a vertically moving cam 31 and a radial moving cam 32 for the retracting hooks 26, 26, a vertically moving cam (not shown) for the stacked coin support rod 28, and A radial moving cam (not shown), a cam (not shown) for operating a roller drive period setting switch that determines the rotational drive period of the packaging rollers 15, 16, and 17 within one packaging cycle, and a camshaft fixed position detection switch. A cam, a cam for operating a paper feed start switch, a cam for a paper cutting timing switch, etc. are fixed. This camshaft 29 is a camshaft motor
M ₁ , a gear 34 fixed to the motor shaft 33;
It is driven through an intermediate gear 35 and a gear 36.

The support rod 23 that supports the packaging roller 17 is formed with forked portions 23a and 23b.
3a is loosely supported on a support shaft 37 so as to be able to swing around this support 37, and a roller 38 is pivotally supported on the forked portion 23b, and this roller 38 is connected to one end of a lever 39. It is loosely fitted into the elongated hole 40 of. The lever 39 is supported so as to be able to swing around a support shaft 41. A follower 42 that contacts the cam 30 is pivotally supported at the other end of the lever 39, and a tension spring 43 prevents the follower 42 from coming into contact with the cam 30. is guaranteed.

The packaging rollers 15, 16, and 17 are three co-driven rotary packaging rollers, and are connected to a motor _M2 and a motor shaft 4.
4, a friction disk 45 fixed to the shaft 44, and the motor shaft 44 are free to rotate, and the shaft 4 is fixed to the friction disk 45.
A pulley 46 that is pressed by springs (not shown) in four directions to make frictional contact and normally rotates integrally with the friction disk 45 due to the frictional contact; a belt 47 that has one end wound around the pulley 46; belt 47
A pulley 48 around which the other end is wound, and a gear 5 on a pulley shaft 49 to which this pulley 48 is fixed.
0,51, and gears 52,5 that mesh with this gear 51.
The packaging rollers 15, 16 are driven by
The wrapping roller 17 is driven through 58.

A detection disk 59 is fixed to the pulley 46, and a detector 60 consisting of a proximity switch, a light emitter/receiver, or the like faces the periphery of the detection disk 59. The detector 60 detects the jamming of wrapping paper and stacked coins in the packaging space 25 during one packaging cycle, and when the detection disc 59 is rotating integrally with the friction disc 45 and pulley 46, Continuous pulses are detected by the uneven portion formed at a constant pitch along the entire periphery of the detection disk 59, and if the wrapping paper and stacked coins are caught in the wrapping space 25, the wrapping rollers 15, 16 ,1
When braking force is applied to either of the pulleys 46 and the detection disk 59, the rotational speed of the pulley 46 and the detection disk 59 decreases or stops rotating, and the pulley 46 and the rotating friction disk 4
5, a slip occurs between the two. This detection disk 59
Due to the speed reduction or rotation stop, the detector 60 does not detect continuous pulses at constant time intervals, but detects the occurrence of wrapping paper and stacked coins being caught.

Note that the driving rotation period of the packaging rollers 15, 16, 17, that is, the rotation period of the motor _M2 is the same as that of the camshaft 2.
This is a predetermined period of time during one rotation of coins 9, and specifically, from a point slightly earlier than when the wrapping rollers 15, 16, and 17 start moving to pick up stacked coins, the top and bottom of the wrapping paper that is wrapped around stacked coins is This is the period immediately after the end of crimping of the protruding edge (see Figure 6).

(Structure of Paper Feeding Section) The paper feeding section G includes a disk 62 on which the lower edge of the wrapping paper roller 61 wound into a roller shape is placed, and a disk 62 fixed at the center of the disk 62 and holding the wrapping paper roller 61. A wrapping paper roll support part consisting of a support shaft 63 inserted into the winding core hole is provided, and a predetermined braking force is applied to the disc 62 in the winding direction of the wrapping paper roll 61 by a mechanism not shown, and the wrapping paper roll When the wrapping paper No. 61 is stretched, inertial rotation due to the pulling force is prevented. The wrapping paper portion pulled out from the wrapping paper roller 61 is clamped between paper feed rollers 64 and 65. At least one of the paper feed rollers 64 and 65,
That is, in this example, the paper feed roller 64 is a driven roller driven by a paper feed motor _M3 , and is driven and rotated at a predetermined time of one packaging cycle to perform a paper feeding operation.

The paper feed path 66 includes a fixed guide 68 that guides the wrapping paper from the positions of the paper feed rollers 64 and 65 to the side position of the cutter 67, a curved guide plate 69 provided following the fixed guide 68, and a guide plate 69 that is provided following the fixed guide 68. It consists of a fixed guide 70 provided following the plate 69 and a machine top surface 71 that is flat and at the same height as the top surface of the disk 62. The guide plate 69 has one end near the cutter 67 pivoted by a support shaft 72, and the guide plate 69 is normally located at the solid line position in FIG. ,
Alternatively, when repairing or inspecting the paper feed passage 66 or the like, it can be opened and stopped at the position shown by the dashed line in FIG. Note that the fixed guide 70 is a common member and serves as the paper guide 18.

The cutter 67 cuts the wrapping paper portion pulled out from the wrapping paper roll 61 to form a wrapping paper piece of a predetermined length, and has a sharp mountain-shaped blade with a protruding edge at the vertical center position.

A plate spring 73 is fixed to the surface of the cutter 67 on the fixed guide 68 side, and the tip of the protruding V-shaped wrapping paper that is cut by the cutter 67 and newly formed is separated from the cutter 67 by the plate spring 73. and is deflected by the fixed guide 68. A movable paper guide 74 is pivotally supported on the shaft of the packaging roller 15.
It is positioned at the solid line position in FIG. 2 by a stopper and tension spring (not shown). This movable paper guide 74 prevents the leading edge of the wrapping paper from separating from the guide plate 69 and the fixed guide 70 due to curling when it is fed along the guide plate 69 and the fixed guide 70, and cooperates with the fixed guide 70 to prevent the wrapping paper from separating from the guide plate 69 and the fixed guide 70. It has the role of guiding the leading end between the fixed guide 70 and the packaging roller 15. Also, when the stacked coins are clamped and rotated by the wrapping rollers 15, 16, and 17, the tip of the wrapping paper is fed into the wrapping roller 15 and the circumferential surface of the stacked coins, and the wrapping paper is sequentially attached to the circumferential surface of the stacked coins. As the wrapping paper is wound, the trailing portion of the wrapping paper that was aligned with the guide plate 69 and the fixed guide 70 is gradually tensioned, and with this tension, the movable paper guide 74 is moved against the tension spring (not shown) to the wrapping roller 15. It is rotated clockwise in the figure around the axis. When this movable paper guide 74 is rotated to the position indicated by the dashed-dotted line in FIG.
When the wrapping paper returns to the solid line position in FIG. 2, the trailing portion of the wrapping paper is pushed back toward the fixed guide 70.

A detection piece 75 is fixed to this movable paper guide 74, and a detector 76 that detects the reciprocating rocking motion of this detection piece 75 detects whether or not the wrapping paper is cut. Note that the detection period by the detector 76 is set as a condition, and whether or not the wrapping paper is cut depends on whether the detector 76 detects the reciprocating swing motion of the detection piece 75 within a predetermined time from a predetermined time in one packaging cycle. It is becoming detected.

(Operation of the entire coin wrapping machine) Next, the operation of the coin wrapping machine as a whole will be explained.

The coins stored in the storage hopper section A of FIG. 1 are sent onto a rotating disk 3 by a disk 2, and are moved to the periphery of the disk 3 by the centrifugal force of the disk 3. During the movement, the coins are further conditioned in the thickness direction by the coin thickness regulating member 5 and sent out, and the sent coins are regulated and aligned in a line at the entrance of the coin passage section C, and are forcibly transferred within the same passage section C by the transfer belt 9. . While the coins are being conveyed, small-diameter coins mixed in with the coins are removed into the sorting slot, and only coins of regular denominations are sent to the coin stacking section E after passing through the sensor 10 of the coin counting section D. , when feeding the coins, the stacking belt 12,1
2 is driven by a predetermined pitch and the coin supporting portion 12
Coins are sequentially stacked on a and 12a. When the coin counting unit D counts the number of coins in a packaging unit, the stopper 11 advances to stop the next coin of that number, and also temporarily stops the rotating disk 3 and the conveyor belt 9. In addition, the counting signal of the number of packaging units from the sensor 10 causes the stacking belts 12, 12 to continuously rotate, and after lowering the opposite inner surface side of the belt, the outer surface side is raised and facing again. Position it at the upper initial position on the inner surface side. The stacked coins placed on the coin supports 12a, 12a are then placed on the opening/closing shutter 14 and held there. Next, the coefficient end signal (S ₁ in FIG. 7) of the number of coins packaged by the coin counting unit D, and the normal position detection signal S ₂ of the normal position detection unit 100 that detects that the camshaft 29 is in the normal position. Both signals of control unit 1
01, the packaging cycle operating section 102
The inner camshaft motor _M1 starts rotating, and the camshaft motor M1 starts rotating.
One rotation of the camshaft 29 completes one cycle of packaging. After the start of one rotation of the camshaft 29, the stacked coin support rod 28 is first moved in the radial direction from the lower side of the space 25 to be directly under the space 25, and then ascends within the space 25 to open/close. It reaches the lower part of the shutter 14. Immediately after that, a cam switch (not shown) on the camshaft 29 is switched to a predetermined angle rotation timing of the camshaft 29, and a shutter solenoid (not shown) is activated to open/close the shutter 14. Let it open. Upon opening, the stacked coins are transferred onto the stacked coin support rod 28, and as the support rod 28 is lowered, the stacked coins are also lowered. When the upper end of the stacked coins moves downward from the opening/closing shutter 14, the cam switch is switched back and the shutter solenoid is deactivated and the opening/closing shutter 1 is turned off.
Close 4. In addition, the coin counting section D is operated by a counting start signal _S3 from a counting start switch (not shown) in the control section 101, which is operated by a cam (not shown) on the camshaft 29, and the stopper 11 is moved out of the course. At the same time, the rotating disk 3 and the transfer belt 9 are driven to restart counting and piling operations.

The stacked coin support rod 28 continues to descend within the space 25, descends to the wrapping position, and is temporarily stopped.

At that time, the follower 42 is displaced from the large-diameter cam surface to the small-diameter cam surface of the cam 30 for moving the packaging roller. This displacement movement of the follower 42 causes the lever 39 to rotate the support rod 23 clockwise about the support shaft 37, thereby bringing the wrapping roller 17 into pressure contact with the circumferential surface of the stacked coins. As a result, the stacked coins on the stacked coin support rod 28 immediately after being lowered to the wrapping position and temporarily stopped are clamped by the wrapping rollers 15, 16, and 17. As a result of this clamping, the wrapping roller 17 is prevented from moving on the circumferential surface of the stacked coins, the support rod 23 and the lever 39 are also prevented from swinging, and the follower 42 is not in contact with the small diameter cam surface of the cam 30. placed in a displaced position.

The movement of the packaging roller 17 to the stacked coin clamping position is performed by the cam plate 24 on the support rod 23 and the follower 2.
2, the paper guide 20 is positioned at a position corresponding to the coin diameter, and the paper guide 19, which is interlocked and moved through the paper guide 20, is also positioned at a position corresponding to the coin diameter. Moreover, since the paper guide 21 also moves integrally with the packaging roller 17, the packaging roller 15,
Paper guides 18, 19, 20, and 21 are positioned at appropriate positions relative to the circumferential surface of the stacked coins to be clamped at 16 and 17 (see FIG. 3).

The wrapping rollers 15, 16, and 17 are rotated slightly earlier than when they start moving to pick up the stacked coins, and at the same time as the wrapping rollers 15, 16, and 17 pick up the stacked coins, the stacked coins are be rotated.
The rotation of the packaging rollers 15, 16, 17 is controlled by a seventh actuation cam (not shown) on the camshaft 29.
The packaging roller drive period setting switch (not shown) in the control unit 101 shown in the figure is switched to rotate the motor _M2 of the packaging roller rotation drive unit 103, causing friction between the motor shaft 44, the friction disc 45, and this disc 45. Pulley 46, belt 47, pulley 48, pulley shaft 49, gears 50, 51, 5 that are rotated in contact with each other
Packaging rollers 15 and 16 are driven and rotated through gears 54 and 55, which mesh with gear 51.
The packaging roller 17 is driven to rotate via 56, 57, 58.

On the other hand, one regular packaging cycle (excluding the first packaging cycle of stacked coins that is wrapped immediately after the start)
(referring to each subsequent normal packaging cycle), at the beginning of one packaging cycle, that is, when the camshaft 29 is in the fixed position, the tip of the pulled-out portion of the wrapping paper is The wrapping paper part is located at the guide plate 69.
and is in a state where it is deflected by the fixed guide 68.
When one packaging cycle starts, that is, when the rotation of the camshaft 29 starts, a paper feed start switch (not shown) in the control section 101 shown in FIG. 7 is actuated by the cam (not shown) of the camshaft 29. , the number of pulses corresponding to the paper feed length _l1 is applied to the pulse motor _M3 , the motor _M3 of the paper feed roller drive unit 104 is rotated by the corresponding amount, and the wrapping paper is rolled to a predetermined length by the paper feed rollers 64 and 65. Sent for ₁ minute. This paper feeding operation of the predetermined length _l1 is the primary paper feeding operation. As a result, the leading edge of the wrapping paper is deflected by the guide plate 69 and the fixed guide 70 and reaches the Z position shown in FIGS. 2 and 5. At this time, a cam (not shown) on the camshaft 29 switches the paper feed start switch (not shown) in the control unit ₁₀₁ shown in FIG. Paper motion is also paused. As a result, the leading edge of the wrapping paper is temporarily stopped at the Z position, but
At this time, the stacked coins are descending within the space 25 and are not being clamped by the wrapping rollers 15, 16, 17. Next, the stacked coins are wrapped around the wrapping rollers 15, 1.
6, 17, each packaging roller 15, 1
Since the coins 6 and 17 are driven and rotated, the stacked coins are also rotated. Immediately thereafter, the cam of the camshaft 29 switches the paper feed start switch (not shown) in the control section 101 in FIG. 7 again, and the motor _M3 in the paper feed roller drive section 104 in FIG. 7 rotates. is,
The leading edge of the wrapping paper passes through the paper feed rollers 64 and 65.
The coins are moved again from the Z position shown in the figures and FIG. 5 and fed between the circumferential surface of the stacked coins, which are rotated by the wrapping rollers 15, 16, and 17, and the circumferential surface of the wrapping roller 15. This paper feeding operation is a secondary paper feeding operation, and this paper feeding operation continues until the paper cut detector 76 detects the cutting of the wrapping paper, and when the wrapping paper is detected to be cut, the motor M ₃ is stopped and the paper feeding operation is stopped. The process ends when the paper rollers 64, 65 are stopped. In other words, when the leading edge of the wrapping paper is caught between the circumferential surface of stacked coins and the wrapping roller 15, the circumferential speed of the wrapping rollers 15, 16, 17 is much faster than the circumferential speed of the paper feed rollers 64, 65. It is wound around the peripheral surface of the stacked coins through the wrapping roller 15, paper guide 19, wrapping roller 16, paper guide 20, paper guide 21, wrapping roller 17, paper guide 21, and paper guide 18 shown in the second diagram. As a result, the trailing portion of the wrapping paper that was along the fixed guide 70 and the guide plate 69 is gradually stretched between the wrapping roller and the cutter 67, becomes straight, is pressed against the cutter 67, and is cut. By cutting this wrapping paper, the movable paper guide 74 is returned from the solid line position in FIG. be done.

The paper cutting detection signal _S4 from the detector 76 is sent to the control unit 1.
This signal _S4 is input to the control unit 1 during the rotation of the camshaft 29 from a predetermined angle to a predetermined angle.
Only when input to 01 is entered, the post-war 101 disconnects the paper cutting as ``yes'' and the normal steady packaging cycle (shown in FIG. 6a, which will be described later) continues. If the paper cutting detection signal S ₄ from the detector 76 is not input to the control unit 101, or if the detection signal S ₄ is input to the control unit 101 outside the above-mentioned predetermined rotation angle period of the camshaft 29, the control The unit 101 determines that there is no paper cutting, and the motor in the packaging roller rotation drive unit 103
Immediately stop _M2 and wrap the packaging rollers 15, 16,
Stop the rotation of 17. On the other hand, the motor _M1 of the packaging cycle operating section 102 is stopped when the camshaft 29 returns to its normal position. For motor _M3 ,
No rotation is performed for the tertiary feeding operation.

When the control unit 101 determines that the above-mentioned paper cutting is “present”, the control unit 101 first stops the rotation of the motor M ₃ of the paper feed roller drive unit 104 . This ends the secondary paper feeding operation described above, but the amount of paper fed by the paper feed rollers 64 and 65 during the secondary paper feeding operation is _lX (this _lX depends on whether the paper is cut early or late). variable length). Upon completion of this secondary paper feeding operation, the leading edge of the wrapping paper newly formed by being cut by the cutter 67 is
located in position. On the other hand, the wrapping paper pieces that are being wrapped around the periphery of the stacked coins are wrapped around the wrapping rollers 15 and 1.
6 and 17, the coins are further wrapped around the periphery of the coin, and the winding hooks 26,
26 moves in the radial direction of the side of the space 25 to reach above and below the wrapping paper protruding edges protruding from the stacked coins, and then moves in a direction approaching each other to apply the upper and lower wrapping paper protruding edges. Tighten. When the crimping operation is completed, the retracting hooks 26, 26 move in directions away from each other, then move in the radial direction, retreat to the outside of the space 25, and stop. When the tightening operation by the winding hooks 26, 26 is completed, the operating cam (not shown) of the camshaft 29 switches the roller drive period setting switch (not shown) in the control section 101 shown in FIG. The motor _M2 in the packaging roller rotation drive unit 103 in FIG. 7 is rotated, and the packaging rollers 15, 16,
The drive rotation of 17 is stopped. On the other hand, the stacked coin support rod 28 that supported the bottom surface of the stacked coins just before that.
It descends and retreats to the radial side of the space 25.

Next, the large-diameter cam surface of the cam 30 of the camshaft 29 comes into contact with the follower 42, and the packaging roller 17 moves to the solid line position in FIG. 2 through the lever 39 and the support rod 26. By this movement of the wrapping roller 17, the wrapped coin is dropped downward and is ejected to the ejection section H. Immediately after the packaging roller 17 returns to the opening direction, the camshaft 29 returns to the home position by one rotation, and the home position detection unit 100 receives the signal S ₂
is input to the control unit 101, and if the coin counting unit D has finished counting the next packaging unit number of coins at the time of return, the coin counting unit D also sends the signal _S1 to the control unit 101.
, the control unit 101 continues the rotation of the motor _M1 in the packaging cycle operation unit 102, and if the coin counting unit D has not yet finished counting the number of coins in the next packaging unit, the number of coins in the next packaging unit is The motor _M1 is stopped until the signal _S1 is input to the control section 101, and the camshaft 29 is stopped at a fixed position.

In addition, in the above-mentioned normal steady packaging cycle, at a predetermined time after the paper cut is detected, a paper feed start switch (not shown) in the control unit 101 shown in FIG. Then, the number of pulses corresponding to the predetermined paper feeding length _l2 is applied to the pulse motor _M3 in the paper feed roller drive unit 104, and the motor
Paper feed rollers 64 and 65 are rotated by a predetermined amount of rotation of _M3 .
is rotated by a corresponding amount to perform the tertiary sheet feeding operation. At the end of the above-mentioned secondary paper feeding operation, the cutter 6
The tip of the newly formed wrapping paper cut at 7 is pushed back from the cutter 67 by the leaf spring 73 and moved to the X position (second
With the tertiary sheet feeding operation, the leading end of the wrapping paper is moved along the guide plate 69 to the Y position (shown in FIGS. 2 and 5) and stopped. Then, prepare for the next regular packaging cycle.

(Explanation of the packaging cycle based on the timing table) (1) How to read the timing table Next, referring to the timing table in Figure 6, compare the normal steady packaging cycle a, the regular packaging cycle b at the time of abnormal paper cutting, and the normal first packaging cycle. The cycle c (an abnormal first packaging cycle will also be explained) and the regular packaging cycle d when there is an abnormality in paper jamming will be explained.

The camshaft 29 shown in a, b, c, and d of Fig. 6 is
The rotation period is shown as a line rising above the reference line. The normal rotation period of the packaging rollers 15, 16, and 17 is shown as a rising line above the reference line, and the reverse rotation period is shown as a falling line below the reference line. Or it shows the radial movement of the packaging roller, and more precisely the shape of the cam 30. In other words, the straight line at the top indicates the large-diameter cam surface of the cam 30, and the reference line indicates the small-diameter cam surface of the cam 30.
indicates the rotation period of the paper feed roller 64, and the portion rising above the reference line indicates the rotation time. shows the detection status of the paper cut detector 76, and the rising portion indicates the time when paper cut is detected. Note that the period t ₇ - _{t 6} in a and d and t ₁₃ in c
The period −t ₆ indicates the period during which paper cutting can be detected. Also d
Regarding this, the timing when paper jamming is detected by the wrapping paper jamming detection section 60 is also added, and the part that rises from the reference line indicates the detection timing, t ₁₀ - _{t 6}
The period indicates the period during which wrapping paper can be detected.

Note that the horizontal axis in FIG. 6 indicates time, and for the purpose of explaining the packaging cycle, main times of the packaging cycle are labeled with t ₁ to t ₂₂ . Note that except for c, the progress of time and the rotation angle of the camshaft 29 match, but in the case of c, the camshaft 29 stops rotating midway, so the rotation angle of the camshaft 29 is changed between a and c. I decided to write it down inside.

In the normal stationary packaging cycle of FIG. 6a, the camshaft 29 rotates continuously from time t ₁ to time t ₁₈ , during which it rotates 360°. The correspondence between time and rotation angle is t ₁ (0°), t ₄ (90°), t ₉ (180°), t _1
3
(270°), t ₁₈ (360°). packaging roller 15
，
The rotations 16 and 17 are from time _t3 to time _t14 . The wrapping rollers 15, 16, and 17 move in the radial direction from time _t5 in the stacked coin clamping direction, and come into contact with the periphery of the stacked coins by _t6 . Also, the packaging rollers ₁₅ , 16, and 17 start moving from t 15 (precisely at the time between t ₁₅ and t ₁₇ ),
Returns to initial open position at t ₁₇ . The paper feeding roller 64 performs a first paper feeding operation within a certain period of time from t ₂ to t ₄ and feeds a certain length of paper l ₁ . Further, from _t6 , the second paper feeding operation by the paper feeding roller 64 is started. When the paper cut detection is performed within the paper cut detection possible period from _t6 to _t7 , the rotation of the paper feed roller 64 at that point is stopped, and the secondary paper feed operation is stopped. The start point of the second paper feeding operation of the paper feed roller 64 is constant at _t6 , but the end point is determined by the paper cut detection time, and since it is not a fixed time, the amount of paper fed is l _x (variable value). .

(2) Paper cutting abnormality in normal packaging cycle Cases in which each cutting abnormality occurs in normal packaging cycle are shown in b, but when the paper cutting detector 76 does not detect paper cutting during the detectable period _t6 to _t7 . are the packaging rollers 15, ₁₆ ,
17 is stopped, and the rotation of the paper feed roller 64 is also stopped (the operation is the same as in a until time _t7 in b). However, the camshaft 29 continues for one rotation, and when it reaches the home position, the entire machine stops.

(3) Normal initial packaging cycle c indicates a normal initial packaging cycle. Before starting the initial packaging cycle, wrapping paper is set. In other words, when the undrawn part of the wrapping paper roll that has been used until now becomes too small to be fed out, the unrolled part of the wrapping paper roll (the leading end of the wrapping paper is located between the wrapping roller 15 and the cutter 67) ) is rewound and removed from between the paper feed rollers 64 and 65, and then the core is removed from the support shaft 63. Next, the core of a new wrapping paper roll is loaded onto the support shaft 63, the leading edge of the wrapping paper stuck to the outer peripheral surface of the wrapping paper roll is peeled off, and the core is inserted between paper feed rollers 64 and 65. On the other hand, the guide plate 69 is opened and stopped around the support shaft 72 as indicated by the chain line in FIG. Form a protruding V-shaped tip of the wrapping paper that follows the cutting blade surface. The position of the leading end of the wrapping paper at this time is the position X in FIG. 2 near the cutter 67. In some cases, the operator may further pull out the leading end of the wrapping paper and set it at position Y in FIG. In addition, if the wrapping paper is jammed between the wrapping rollers 15, 16, and 17 during a regular wrapping cycle, the leading end of the wrapping paper is pulled out from between the wrapping rollers 15, 16, and 17 at the end of the wrapping cycle. (The packaging cycle in which the wrapping paper jamming abnormality occurred is detailed in d). The tip of the pulled wrapping paper is damaged and wrinkled as a result of the wrapping paper being bitten, and cannot be reused. Therefore, in this case as well, the guide plate 69 is opened and stopped at the position shown by the dashed dot line in FIG. 2, and the wrapping paper is pressed against the cutter 67 to form a new protruding V-shaped leading end portion of the wrapping paper. At this time, the leading end of the wrapping paper is also located at position X in FIG. 2 near the cutter 67, but some operators may pull out the leading end of the wrapping paper further and set it at position Y in FIG. After forming the new wrapping paper leading end as described above, the guide plate 69 is closed to the solid line position in FIG. 2, and the start button (not shown) of the start command section 105 shown in FIG. 7 is pressed. Then, the signal _S5 from the start command section 105 is input to the control section 101 and stored.
As a result, the initial packaging cycle c is a packaging cycle different from the regular packaging cycle a. That is, in the first packaging cycle c, the camshaft 29 of
Pause when it rotates to 115° (at time t ₆ ). The rotation of the packaging roller starts at time _t3 and continues to rotate at time _t6 , and the packaging roller has completed its closing movement at time _t6 . The paper feeding roller 64 also performs the first paper feeding operation from t ₂ to t ₄ in the same manner as in the regular packaging cycle a. The second paper feeding operation of the paper feeding roller 64 is started from time _t6 ,
This continues until paper cut detection is performed. The position of the leading edge of the wrapping paper at the start of the first packaging cycle may be at the Y position or the X position in Figure 2, and the paper cut detection period is set from t ₆ to t ₁₃ . . This period is a period during which it is possible to feed the amount of paper (l ₁ +l ₂ +l _x ) from the position X in FIG. 2 into the wrapping roller space and to cut the paper by wrapping the wrapping paper around the stacked coins.

Therefore, if the leading edge of the wrapping paper is at the Y position in Figure 2 at the start of the first wrapping cycle, the first paper feeding operation feeds l ₁ of paper to reach the Z position, and the second feeding operation (In principle, up to T ₇ ), the leading edge of the wrapping paper is fed into the wrapping roller space. Furthermore, if the leading edge of the wrapping paper is at the position shown in Figure 2 at the start of the first wrapping cycle, it will be moved between the X position and the Y position ( _{l 2 >} l ₁
), and from the second paper feeding operation (l ₂ + l _X )
The amount of paper fed is fed into the packaging roller space from a position intermediate between the X position and the Y position. In both cases, when the leading end of the wrapping paper is fed into the wrapping roller space, the camshaft 29 has stopped rotating at the 115° position, and the wrapping rollers 15, 16, and 17 are in a rotating state where the stacked coins are being clamped. The tip of the wrapping paper fed into the wrapping roller space is wound around the circumferential surface of the stacked coins. As a result, the trailing portion of the wrapping paper is stretched and cut by the cutter 67. Paper cut detection at that time is performed at time _t12 , the paper feed roller 64 is stopped, and the second paper feeding operation is completed. The amount of paper fed in the second paper feeding operation is (l ₁ +l _X ) or (l ₁ +l ₂ +l _X ) shown in FIG. On the other hand, the camshaft 29 resumes rotation from 115° at the same time as paper cutting is detected at time _t12 , and rotates to 360° at time _t22 , thereby completing the first packaging cycle. The operations of the camshaft, packaging roller rotation, and packaging roller movement in the first packaging cycle from t ₁₂ to t ₂₂ are the same as those in the regular packaging cycle a from t ₆ to t ₁₈ , and also in the first packaging cycle. The tertiary paper feeding operation of the paper feeding roller 64 is
The period from t ₁₇ to t ₂₁ (t ₁₁ of the regular packaging cycle of a)
(corresponding to the period from t ₁₆ to t 16), and the paper feed amount l ₂
is carried out, and the leading end of the wrapping paper, which had been located at the cutter 67 position, is positioned at the start position (Y position) of the regular packaging cycle, in preparation for the subsequent regular packaging cycle.

If paper cutting is not detected by time _t13 in the packaging cycle c, the rotation of the packaging roller is stopped at time _t13 , and the rotation of the paper feed roller 64 from _t17 to _t21 is stopped. No paper feeding operation is performed, and the rotation of the camshaft 29 and the movement of the wrapping roller are performed in the same way as in the normal wrapping cycle of c. However, when the camshaft 29 rotates through 360° at time _t22 , the entire machine is stopped and the next regular packaging cycle is not started.

(4) Paper jamming abnormality in a regular packaging cycle Wrapping paper jamming abnormality in a regular packaging cycle is shown as d, and in this cycle, from t ₁
The process up to time _t8 is the same as in case a. However, at time _t8 , the detector 60 in the wrapping paper jamming detection unit ₁₀₆ in FIG. ) The packaging roller rotation drive unit 1 is controlled by the control unit 101.
03 motor _M2 is stopped, and the packaging rollers 15,
The rotations of 16 and 17 are stopped. Furthermore, the tertiary sheet feeding operation of the sheet feeding roller 64 that should be performed thereafter is not performed (because the sheet feeding roller driving section 104 is not operated by the control section 101 in FIG. 7).

_Note that the detectable time for detecting wrapping paper jamming _{in FIG .} Ru. Also, in the packaging cycle d, the camshaft 29 moves from t ₁ to t ₁₈ as in the steady packaging cycle a.
The 360° rotation up to this point continues, but the camshaft 29 is stopped at time _t18 , and even if the coin counting section D and fixed position detection section 100 shown in _{FIG .} , the camshaft 29 will not start rotating for the next packaging cycle. At this time _t18 , the motor _M3 in the packaging roller rotation drive unit 103 is controlled through the control unit 101 in FIG.
is reversed for a predetermined period (period t ₁₈ to t ₁₉ ) and then stops, at which point the entire machine stops.

The reversal movement of the wrapping rollers 15, 16, 17 from _t18 to _t19 shown in FIG. 6d is carried out for the following purpose. In other words, FIG. 4 shows the state in the middle of the wrapping cycle, and shows the wrapping rollers 15, 16, and 17 rotating to clamp stacked coins (wrapping roller 1
5, 16, and 17 are shown with solid lines; paper guides 19, 20, and 21 are shown with dashed-dotted lines). In this Figure 4, the leading edge of the wrapping paper is connected to the circumferential surface of the stacked coins and the wrapping roller 1.
On the way to the packaging roller 16 passing between the five circumferential surfaces,
It enters between the packaging roller 15 and the paper guide 19,
A solid line indicates a clogged state. In this case, the trailing portion of the wrapping paper is not tensioned, so it is located between the fixed guide 70, the guide plate 69, and the movable paper guide 74 in a wave-shaped state. When wrapping paper is detected, the normal rotation of the packaging rollers 15, 16, 17 is stopped, but since the camshaft 29 continues to rotate until it reaches the fixed position,
When the stacked coin clamps 6 and 17 are released, unwrapped coins are released downward. Note that when a coin is jammed between the wrapping roller 15 and the paper guide 19, the coin remains without being ejected. Then, when the camshaft 29 returns to its normal position, the wrapping rollers 15, 16, and 17 rotate in reverse for a certain period of time from _t18 to _t19 , and as a result, the leading edge of the wrapping paper that has been bitten is moved as shown by the dashed line in FIG. It is pulled out into the space between the wrapping rollers 15, 16, and 17, and becomes free and unrestrained. At this time, the jammed coins are also unjammed and released downward. When the reverse rotation of the wrapping rollers 15, 16, and 17 is completed, the machine stops completely, so the operator opens the guide plate 69 in the direction of the dashed-dotted line in FIG. The packaging roller 15
After pulling it out from between the and fixed guide 70 to the left front side in FIG. 4, it is pressed against the cutter 67 to form a new protruding V-shaped wrapping paper tip. At that time, the tip of the wrapping paper should be
located in position. Depending on the operator, the leading end of the wrapping paper may be pulled out to the Y position for alignment. In this state, the guide plate 69 is closed to the solid line state to prepare for the start of the first packaging cycle (the packaging cycle shown in FIG. 6c).

In addition, the leading edge of the wrapping paper gets caught not only between the wrapping roller 15 and the paper guide 19 described above, but also between the wrapping roller 16 and the paper guide 20, and between the wrapping roller 17 and the paper guide 21 on the lower side in FIG. Packaging roller 1
By reversing steps 5, 16, and 17, it is possible to reliably eliminate wrapping paper jamming at any location. Note that the wrapping paper does not get caught between the wrapping roller 16 and the paper guide 19, and between the wrapping roller 17 and the upper part of the paper guide 21 in FIG. Also, camshaft 2
9, the rotation of the camshaft is interrupted at a predetermined angular position until paper cutting is detected in FIG. 6c. It is conceivable that the rotation of the camshaft is interrupted at a predetermined angular position in the regular packaging cycles a and b to extend the period during which paper cutting can be detected. However, in this case, the waiting time (period from t ₆ to t ₁₃ of c) becomes long for each regular packaging cycle, lengthening the entire packaging operation time and reducing work efficiency. Therefore, in a and b, the rotation of the camshaft 29 is not interrupted at a predetermined angular position.

(5) Modified example of the first packaging cycle Next, as a modified example (1) of _FIG . Rollers 15, 16, 17
There is also a method in which the rotation of the camshaft 29 is stopped after being reversed for a certain period of time, and the camshaft 29 resumes rotation immediately thereafter to return to the home position, thereby stopping the entire machine. In addition, as a modification (2), the camshaft 29 is made to progress in the same packaging cycle as d until the camshaft 29 reaches 270°, and when the camshaft 29 reaches 270°, the rotation of the camshaft 29 is interrupted and the rotation is stopped immediately thereafter. packaging rollers 15, 16,
17 is reversed for a predetermined period of time, and after the reverse rotation has stopped, the camshaft 29 is rotated again while the packaging rollers 15, 16, and 17 are stopped to rotate to a 360° position, and then the entire machine is stopped.

(6) Another example of the detector of the wrapping paper jamming detection unit Next, as another example (1) of the detector 60 of the wrapping paper jamming detection unit 106, the movable wrapping roller 17 is used to clamp stacked coins. There is a method that detects when stacked coins are not moved to the radial position where they should be pinched, and detects when the coins move excessively beyond that radial position, and determines that the wrapping paper is caught in each of these detections. Specifically, this is performed using a detector that detects the swinging position of the support gap 23. In another embodiment (2), for example, the paper guide 20 is made of a conductive material, the support gap 28 is also made of a conductive material, and the paper guide 20 and the support gap 28 are provided with an insulating material interposed therebetween. Furthermore, the packaging rollers 15, 16, and 17 are made of an insulating material. Therefore, under normal packaging conditions, there is no electrical conduction between the paper guide 20 and the support rod 28. However, when a coin collapses and some of the stacked coins come into contact with the paper guide 20, electrical conduction occurs between the paper guide 20 and the support rod 28 via the paper guide 20 - the broken coin - the stacked coins - the support rod 28. . By detecting this conduction, it is possible to detect whether the wrapping paper is caught. These examples directly detect the deformation of stacked coins, but when the coin deforms, the wrapping paper is not wrapped around it, and in most cases the wrapping paper is caught. .

As described above, when the wrapping paper is caught in the wrapping section, all the wrapping rollers are driven in reverse when the wrapping cycle is stopped and the wrapping paper is caught, so that the wrapping paper that has been caught once is also removed. It is pulled back from the gap between the wrapping roller and the paper guide, and the jamming is released.

〔Effect of the invention〕

As explained above, the method of releasing the jammed wrapping paper according to the present invention not only facilitates the removal of the jammed wrapping paper from the packaging section, but also makes it possible to remove all the wrapping rollers from the correct position when detecting the wrapping paper. Since the rolling drive is stopped, there is no further deterioration of the wrapping paper jamming condition, and it has excellent effects such as being able to minimize damage to the wrapping roller, coins, deformation of the paper guide, etc.
