BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin wrapping machine, and more particularly to a coin wrapping machine that cuts wrapping paper when the number of stacked stacked coins is excessive or insufficient.

[0002]

2. Description of the Related Art A coin wrapping machine which cuts a wrapping paper that wraps the accumulated coins when the number of accumulated coins is excessive or insufficient has been disclosed in Japanese Patent Laid-Open No. 175956/1995. Things are known. This device discriminates the authenticity and denomination of inserted coins, and a coin discriminating and counting means for counting the number of coins, a coin accumulating means for accumulating a predetermined number of coins of a denomination to be packed, and a predetermined number of coins. Wrapping means for wrapping a wrapping paper having a width wider than the height of the accumulated coin around the accumulated coin so that a crimped portion for crimping the accumulated coin remains on the accumulated coin; A pair of upper and lower crimping claws that are movable and are moved so as to be close to each other, sandwich the accumulated coins therebetween, and swage the crimped portion of the wrapping paper to generate a wrapped coin; An excess / deficiency detection means for detecting whether or not there is an excess or deficiency in the number of accumulated coins after winding the wrapping paper around the accumulated coins, and the accumulated coins when it is detected that the number of accumulated coins is insufficient. Wrapping paper cutting hand to cut wrapping paper It is provided with a door. The wrapping paper cutting means is provided with a cutter and a solenoid for advancing and retracting the cutter fixed to the tip of the movable portion toward the packaging coin.

According to this coin wrapping machine, after the inserted coins are discriminated and counted, a predetermined number of coins are stacked in the stacking unit and conveyed to the wrapping unit, and the wrapping paper is sandwiched by a plurality of wrapping rollers in the wrapping unit. By being wrapped and the upper and lower ends of the wrapping paper are crimped by the pair of upper and lower crimping claws,
Wrapping coins are generated. At this time, the height of the stacked coins to be wrapped is calculated based on the amount of movement of the crimp claws, and it is determined whether or not the number of stacked coins is excessive or insufficient.

As a result, if there is no excess or deficiency in the number of stacked sheets,
While the packaging roller is opened and the packaging coins are collected,
When it is determined that the number of stacked sheets is excessive or insufficient, the cutter is caused to project toward the packaging coin by the operation of the solenoid. Since the wrapping coin is rotated around its vertical axis while being held by the wrapping roller, the cutter blade edge is brought into contact with the wrapping paper of the rotating wrapping coin to cut the wrapping paper in the circumferential direction. Thus, the packaging coins having an excess or deficiency in the number of accumulated coins can be distinguished from the regular packaging coins.

[0005]

However, in the above conventional coin wrapping machine, the cutter for cutting the wrapping paper is
Since the movable part of the solenoid is instantly advanced and the blade edge of the cutter fixed to the movable part is brought into contact with the wrapping paper of the rotating packaging coin, the wrapping paper is cut. It is conceivable that the blade edge of the cutter will be heavily loaded by the force and will be worn or damaged early.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to suppress the occurrence of abrasion or damage in a cutter that cuts the wrapping paper of packaging coins having an excess and deficiency in the number of stacked sheets and surely wraps the wrapping paper. It is an object of the present invention to provide a coin packaging machine capable of cutting a coin.

[0007]

In order to achieve the above object, the present invention selects a predetermined number of coins by stacking them up and down in a stacking unit after selecting and counting the denominations of a plurality of inserted coins. Forming a columnar integrated coin consisting of, and wrapping the wrapping paper around the peripheral surface of the integrated coin while rotating by sandwiching the integrated coin by a plurality of wrapping rollers from the outside in the radial direction in the wrapping section, and A coin wrapping machine for forming a packaging coin by crimping the upper and lower ends with a pair of upper and lower crimping claws, and detecting whether there is an excess or deficiency in the number of accumulated coins in the packaging coin. Means and wrapping paper cutting means for cutting the wrapping paper of the wrapping coin when it is detected by the excess / deficiency detecting means that there is an excess or deficiency in the number of stacked coins. Cutting paper And a drive means for moving the cutter back and forth toward the packaging coin rotated between the packaging rollers based on the detection result of the excess and deficiency detection means, the cutter being the packaging coin. We propose a coin wrapping machine that is rotatably supported around an axis parallel to the axis of rotation. Also, the packaging roller
Then, at the middle position in the longitudinal direction of one of the packaging rollers,
The drive is supported so as to be rotatable around the axis of the packaging roller.
A rotation that is rotated by a means over a predetermined angle range.
A moving member is provided, and the cutter is attached to the rotating member.
It is configured.

In the coin wrapping machine, the excess / deficiency detecting means detects the moving amount of the pair of upper and lower crimping claws, and the detected moving amount of the crimping claws and the regular number of sheets. It is effective to include a comparison / determination means for comparing the standard value of the movement amount with the accumulated number of sheets to determine whether or not there is an excess or deficiency.

Furthermore, the cutter, but it may also be constituted by a disc-shaped cutter which is rotatably supported about its centerline arranged cutting edges on the periphery.

Further, it is more effective if the cutter is arranged so as to be brought close to the surface of the wrapping paper from the rear side in the rotation direction of the wrapping paper.

[0011]

According to the coin wrapping machine 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. Also,
The longitudinal direction of any one of the packaging rollers
Is rotatably supported around the axis of the packaging roller at an intermediate position of
Hold and rotate by drive means over a predetermined angle range
Is provided with a rotating member, and the cutter is attached to the rotating member.
If it is attached, it will rotate by the operation of the drive means.
When the member is rotated, it is attached to the rotating member.
The cutter is brought close to the peripheral surface of the packaging coin at a shallow angle.
It For this reason, the cutting edge of the cutter suddenly bites into the wrapping paper.
Is avoided, and excessive load due to the wrapping paper's rotating force
It is possible to prevent the sharp application to the cutter.
It

Then, by the operation of the excess / deficiency detecting means,
Whether or not there is an excess or deficiency in the number of accumulated coins inside the packaging coin is detected, and when it is detected that there is an excess or deficiency, the wrapping paper cutting means is activated and the wrapping paper of the packaging coin is cut. It In this case, the cutter constituting the wrapping paper cutting means is advanced and retracted toward the peripheral surface of the rotating packaging coin by the operation of the driving means, but can be rotated about the axis parallel to the rotation axis of the packaging coin. Supported by
When the blade edge is brought into contact with the wrapping paper, it is rotated following the moving direction of the wrapping paper. As a result, the load applied to the blade edge of the cutter by the rotating force of the packaging coin is alleviated.

Further, in the above coin wrapping machine, the excess / deficiency detection means detects the movement amount of the pair of upper and lower crimping claws, and the detected movement amount of the crimping claws and the movement amount in the regular number. If it is constituted by a comparison and determination means for comparing the standard value with whether or not there is an excess or deficiency in the number of accumulated coins, the number of accumulated coins in a packed state can be used when performing the crimping work by the crimping claws. It is possible to detect, and the packaging coins having the regular stacking number and the packaging coins having an excessively short stacking number are efficiently classified.

Further, if the cutter is constituted by a disc-shaped cutter which has a blade edge on its peripheral edge and is rotatably supported around its center line, when the blade edge of the cutter comes into contact with the rotating wrapping paper, the wrapping paper is The cutter is rotated so that the cutter is also caught up following the rotation of. As a result, it is possible to avoid applying an excessive load to the cutting edge of the cutter, and the blade edges arranged at the periphery are continuously brought into contact with the wrapping paper, so that the wrapping paper can be reliably cut. Becomes

[0015]

Furthermore, when the cutter is brought closer to the wrapping paper, the cutter is brought closer to the peripheral surface of the rotating packaging coin from the rear side in the rotation direction of the wrapping paper, so that the cutting edge of the cutter comes into contact with the wrapping paper. In doing so, the relative speed between the two becomes smaller than the peripheral speed of the wrapping paper, and the load applied to the cutting edge of the cutter is reduced.

Alternatively, the crimping claws 21 for the regular number of accumulated coins 7 stored in the ROM 27,
By comparing with the standard value of the linear movement amount of 22, if the difference between the two is not within the predetermined error range, it is determined that the number of accumulated sheets is excessive or insufficient.

The wrapping paper cutting means 13 is shown in FIGS.
As shown in FIG. 5, a rotating member 28 disposed coaxially with the fixed wrapping roller 16 and attached rotatably around the axis of the fixed wrapping roller 16, and the rotating member 28.

Further, in the present embodiment, when the solenoid 29 is operated and the cutter 30 is brought closer to the packaging coin, the cutter 30 is brought closer to the peripheral surface of the packaging coin from the rear side in the rotation direction of the packaging coin. It is like this.

Next, the control device 25 for controlling the operation of each of the above mechanical parts will be described with reference to the control block diagram of FIG. The controller 25 includes a counting unit mechanism 36 including a counting motor 31, a counting sensor 32, a stopper 33, an integrated motor 34, and a shutter solenoid 35, a cam motor 37, a rotary encoder 23, and a packaging motor 3.
8. A packaging unit mechanism 40 including a wrapping paper supply motor 39 and a solenoid 29, a ROM 27 in which reference data such as a diameter and thickness of a coin to be handled, an operation program of the entire coin packaging machine, and the like are stored, A RAM 26 for sequentially storing various data such as coin denomination data set for processing, coin count data, accumulated number data, and operating states of various motors, and a denomination of coins for packaging processing are set. It is composed of an operation unit 41, a display unit 42 that displays the count data of the coins that have been packaged, and a CPU 43 that comprehensively controls them.

The counting motor 31 drives the rotating disc 1 and the conveyor belt 3 in the coin passage 2. The counting sensor 32 is a sensor provided in the coin passage 2 and detects the number of coins of a set denomination. Further, the counting sensor 32 includes a material sensor and the like to configure a coin discriminating unit. Is also good. In the stopper 33, the number of coins counted by the counting sensor 32 is equal to
When the number of coins reaches 0, it prevents the subsequent coins from passing. The stacking motor 34 drives the stacking drum 6 of the stacking unit 4 to rotate in association with the detection of coins by the counting sensor 32, thereby stacking coins. The shutter solenoid 35 opens and closes the shutter 8 provided immediately below the stacking unit 4.

The cam motor 37 is a motor for driving a cam shaft to which a plurality of cams are attached so as to interlock the above-mentioned mechanisms, and is composed of, for example, a pulse motor. The wrapping motor 38 uses one fixed wrapping roller 17
It is a motor that rotates the wrapping paper 9 around the accumulated coins 7.
Is to be rotated at a low speed, and the wrapping paper 9 is wound around the accumulated coin 7 one or more times and then rotated at a high speed. The wrapping paper supply motor 39 is used for the wrapping paper 9
The wrapping paper supply roller 19 is driven so as to wind the coins around the stacking coins 7 for about two rotations.

In FIG. 2, reference numerals 44 and 45 are guide plates for guiding the fed wrapping paper 9 between the wrapping rollers 16, 17, 18 and the accumulated coins 7.

The operation of the coin wrapping machine according to this embodiment having the above structure will be described below. First, when coins are inserted into the rotary disc 1, centrifugal forces generated by the rotary disc 1 cause the inserted coins to be 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 37 is driven and the operation of the support post moving mechanism is started. As a result, the support post 15 is arranged at the standby position immediately below the shutter 8.

Further, the accumulated coins 7 are transferred onto the support post 15 by driving the shutter solenoid 35 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 packaging unit 14 by the support posts 15 being lowered by the operation of the support post moving mechanism, and are arranged at the packaging position between the packaging rollers 16, 17, and 18.

When the accumulated coins 7 are placed at the wrapping position, the pressing wrapping roller 18 moves the fixed wrapping rollers 16, 1.
The accumulated coins 7 are nipped between the packaging rollers 16, 17, and 18 by being moved in a direction in which they approach each other. In accordance with this, operation commands are output to the wrapping paper supply motor 39 and the wrapping motor 38, and the wrapping paper supply roller 1
9 and the packaging roller 17 are rotationally driven. As a result, the wrapping paper 9 is supplied between the wrapping rollers 16, 17, 18 and the stacking coins 7 and wound around the stacking coins 7.

After that, the caulking mechanism 11 is operated, and the upper and lower ends of the wrapping paper 9 are paired with the upper and lower caulking claws 21 and 21.
A wrapping coin is completed by being crimped by 2. In this case, the linear movement amount of the crimping claws 21 and 22 for crimping the upper and lower ends of the wrapping paper 9 is, for example, the upper and lower crimping claws 2.
It is measured by the rotary encoder 23 from the initial position where 1 and 22 are maximally separated to the position where they contact the upper and lower end surfaces of the coins 7. Then, the measured value is the CPU 43.
In the comparison and determination means 24 incorporated in the ROM
27 or the standard value stored in the RAM 26, and it is determined whether or not the number of accumulated sheets is excessive or insufficient.

As a result, when it is determined that there is an excess or deficiency in the number of stacked stacked coins 7, the solenoid 2
A drive signal is sent to 9 and, as shown in FIG.
The solenoid 29 is operated, and the cutter 30 is brought into contact with the wrapping paper 9 of the packaging coin through the rotation of the rotating member 28. In this case, since the cutter 30 is rotatably supported around an axis parallel to the rotation axis of the rotating packaging coin, when the cutter 30 receives the rotational force of the packaging paper 9 due to the contact with the packaging paper 9, It can be rotated in a direction that allows the rotational force to escape. This prevents an excessive load from being applied to the cutting edge of the cutter 30.

Further, since the cutter 30 of this embodiment is formed in a disk shape having a cutting edge over the entire circumference, when the cutter 30 comes into contact with the wrapping paper 9 to start cutting, it receives the rotational force of the wrapping paper 9. When it is rotated by being rotated, the cutting is continuously performed so as to be wrapped around the wrapping paper 9. As a result, the wrapping paper 9 can be reliably cut.

Further, the cutter 30 is attached to a rotating member 28 arranged coaxially with the fixed packaging roller 16, and is moved by drawing an arcuate locus by the operation of a solenoid 29 to move its cutting edge. It comes into contact with the peripheral surface of the packaging coin. Therefore, the cutter 30 uses the wrapping paper 9
Since it is made to approach the wrapping paper 9 at a shallow angle, that is, at an acute angle with respect to the tangent to the peripheral surface of the wrapping paper 9, the wrapping paper 9 is gradually cut. As a result, it is possible to prevent an excessive load from being instantaneously applied to the cutting edge of the cutter 30.

Moreover, since the cutter 30 is arranged so as to be brought close to the wrapping paper 9 from the rear in the direction of rotation of the packaging coins, the cutter 30 and the wrapping paper 9 when coming into contact with the wrapping paper 9 are separated from each other. The relative speed will be reduced. As a result, the load applied to the cutting edge of the cutter 30 is also reduced.

Therefore, the cutter 3 for cutting the wrapping paper 9
Since the load due to the rotational force of the wrapping paper 9 applied to the blade edge of 0 is effectively reduced, it is possible to prevent the blade edge of the cutter 30 from being worn or damaged early. Further, the wrapping paper 9 of the packaging coins having the excess and deficiency in the number of accumulated coins can be surely cut, and such an incorrect packaging coin can be reliably distinguished from the regular number of the accumulated coins.

As a result of the judgment by the comparison judging means 24, when it is judged that there is no excess or deficiency in the number of accumulated coins inside the packaging coin, the wrapping paper cutting means 13 is not operated and the wrapping roller 16 is not operated. , 17, 18 are separated from each other, and the completed proper packaging coin is discharged to a roll chute (not shown).

In the coin wrapping machine according to this embodiment,
Although the cutter 30 of the wrapping paper cutting means 13 is brought close to the peripheral surface of the wrapping coin by the rotating member 28 rotatably mounted coaxially on the wrapping roller 16, instead of this,
If space permits, it may be attached by another rotating member arranged independently of the packaging roller or by another moving member. Further, although the disk-shaped cutter 30 is adopted as the cutter 30, instead of this, a cutter having a blade edge that can be swung around an axis parallel to the rotation axis of the packaging coin may be adopted. In this case, it is necessary to provide an arbitrary urging means so as to urge the blade tip toward the wrapping paper while releasing the rotational force from the wrapping paper to the blade tip to some extent.

Further, although the spring return type solenoid 29 is adopted as the driving means, it goes without saying that any other actuator can be adopted instead of this. Further, in the present embodiment, the wrapping paper cutting means 13 is provided with three wrapping rollers 16, 17,
Fixed wrapping rollers 16, 17 whose positions within 18 are fixed
However, the present invention is not limited to this, and the fixed packaging rollers 16 and 17 may be provided together with the pressing packaging roller 18 which can be horizontally contacted and separated.

In addition, the wrapping paper cutting means 13 of this embodiment
Is not limited to the wrapping mechanism 10 in which two of the wrapping rollers 16, 17, 18 are fixed wrapping rollers 16, 17, and one is the holding wrapping roller 18, one fixed wrapping roller and two horizontal wrapping rollers. It is also possible to apply the present invention to a packaging mechanism configured by a movable packaging roller that can be brought into contact with and separated from each other, and further, three moving packaging rollers that can be brought into and out from each other in the horizontal direction.

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 transferred on the support post 15. When a predetermined number of coins are accumulated by the accumulation drum 6 without the
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.

[0050]

As described in detail above, according to the coin wrapping machine of the present invention, when the excess / deficiency detecting means detects that the number of stacked sheets is excessive or insufficient, the coins are rotated between the packaging rollers. By advancing the cutter toward the existing packaging coins, the wrapping paper of the packaging coins is cut, and the regular stacking number of the packaging coins can be clearly distinguished. In this case, the cutter that has come into contact with the wrapping paper is rotated in a direction in which the blade tip escapes with respect to the rotation of the packaging coin, and thus the force that the blade tip receives from the wrapping paper can be sufficiently reduced. As a result, it is possible to reliably prevent the cutting edge from being worn or damaged at an early stage. In addition, one of the packaging rollers
At the midway position in the longitudinal direction of the roller,
And a rotating member that is rotatably supported
By attaching the cutter to the material, the cutter is wrapped
The blade edge to the wrapping paper abruptly.
It is possible to prevent biting. This will
Prevent a large amount of force from being applied to the cutter, and
Can be protected.

Further, if the excess / deficiency detection means is constituted by the comparison / determination means for determining the excess / deficiency of the number of stacked sheets from the movement amount of the pair of upper and lower crimping claws, the excess / deficiency of the stacked sheets can be detected while crimping the packaging paper. , It is possible to efficiently distinguish between the regular number of packaging coins and the improper packaging coins. Further, since it is not necessary to dispose a special sensor or the like, it is possible to save space in the mechanism of the coin packaging machine.

If the cutter is a disk-shaped cutter that is rotatably supported about its center line, the rotational force transmitted from the wrapping paper is released by rotating the cutter, and the cutting edge is applied to the wrapping paper. Is continuously supplied, and the wrapping paper can be reliably cut.

[0053]

Further, when the cutter is brought close to the wrapping paper, the cutter blade edge is brought into contact with the wrapping paper by bringing the cutter close to the peripheral surface of the rotating packaging coin from the rear in the rotation direction of the wrapping paper. In doing so, the relative speed between the two can be made smaller than the peripheral speed of the wrapping paper, and the load applied to the cutting edge of the cutter can be reduced. As a result, the cutting edge of the cutter can be more reliably protected from wear and damage.
