CONSTITUTION:A control system of a coin packaging machine is constructed of a rotary encoder 14, a coin packaging control mechanism 50, a packed-bar quantity-counting means 51, a memory 52 for storing reference data classified by kinds of coins, a memory 53 storing permissible values, a data operating part 54, a part 55 judging comparison within allowance, a memory 56 storing detecting data and an over-and-short detection control part 57. In the case where the data detecting accumulated height of packed coins (the amount of movement of a compacting claw detected by the rotary encoder 14) exceeds continuously the allowable limit set for the reference data, a judgement is made that the position of the compacting claw is slipping off by some reasons including replacement or adjustment of the compacting claw. Then the reference data are corrected, based on the detected data, for succeeding operations.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excess and deficiency detection mechanism for a coin wrapping machine, which prevents a erroneous determination that a predetermined number of normally packed coins are abnormally packed coins.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Laid-Open No. 3-612, when a wrapping paper is wrapped around a predetermined number of coins (for example, 50 coins) and wrapped by a coin wrapping machine, some kind of coin wrapping is performed. A coin excess / deficiency detection device that prevents the packed coins (for example, 49-pack, 51-pack, etc.) having an excess or deficiency in the predetermined number due to the above from being discharged from the chute as the normal packaging coins having the predetermined number of packages. Is provided. In the device described in the above publication, after wrapping the wrapping paper around the accumulated coins,
A rotary encoder detects the amount of movement of the crimping claws that crimp the upper and lower edges of the wrapping paper close to the upper and lower ends of the stacked coins, and compares the detected value of the moving amount with a prestored reference value. Thus, it is possible to detect whether or not a predetermined number of coins have been wrapped.

[0003]

However, in the conventional coin wrapping machine described above, when a crimping claw that has become unusable due to, for example, wear is replaced with a new crimping claw, the exchanged crimp The disposition position of the claw may be slightly different from the regular position. When the position of the crimping pawl is deviated from the normal position in this way, the detected value of the amount of movement of the crimping pawl by the rotary encoder is within the allowable range with respect to the reference value, although a predetermined number of coins are packed. As a result, there is a problem that a normal packaged coin packed in a predetermined number of sheets is erroneously determined as an abnormal packaged coin.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an excess / deficiency detection mechanism for a coin wrapping machine, which prevents a problem of erroneously determining a normal packaging coin having a predetermined number of packaging as an abnormal packaging coin.

[0005]

In order to achieve the above-mentioned object, the present invention provides a wrapping film having a width larger than the height of the accumulated coins around a predetermined number of accumulated coins. In a coin wrapping machine for forming a packaging coin by holding a stacked coin by a pair of crimping claws that are movable so as to be close to each other Detecting means for detecting the cumulative height of the packaging coins as the amount of movement of the crimping claws; storage means for storing in advance reference data corresponding to the cumulative height of the normal packaging coins packed by a predetermined number; and the detecting means. When the detected data exceeds the allowable range for the reference data at least twice in succession, the reference data stored in the storage device is compared with the reference data stored in the storage device. Characterized by comprising the excess detection control means for correcting, based on the output data.

[0006]

According to the present invention, when the detection data of the cumulative height of the packaging coin exceeds the allowable range with respect to the reference data at least twice or more in succession, for example, replacement or adjustment of the caulking claw is performed. It is determined that the position of the crimping claw has been displaced due to the cause of the above, and then the reference data is corrected based on the detected data, so it is always possible to accurately determine and process whether there is excess or deficiency in the packaging coins. it can. As a result, as in the conventional case, when the position of the crimping claw is deviated from the normal position, a normal packaging coin that has been packaged a prescribed number of coins despite being packaged with a prescribed number of coins is mistaken as an abnormal packaging coin. It is possible to eliminate the determination problem.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an excess / deficiency detection mechanism of the coin wrapping machine of this embodiment, in which the detection data of the cumulative height of the packaging coins (movement amount of the crimping claws detected by a rotary encoder described later) is within an allowable range with respect to the reference data. If it exceeds continuously, it is judged that the position of the caulking claw has shifted due to some cause such as replacement or adjustment of the caulking claw, and then the reference data is corrected based on the detected data. In this way, it is possible to prevent a problem that a normal packaged coin, which has been packaged in a predetermined number as in the conventional case, is erroneously determined as an abnormal packaged coin.

A coin discriminating and counting unit (not shown) discriminates and counts authenticity and denomination, selects only coins of denominations to be packed, sends out a predetermined number of coins to a coin accumulating unit (not shown), and accumulates them. The coins 1 in the shape of a circle are placed on the support rods 2 and transferred to the packaging position of the coin packaging unit. After that, the packaging film 3 having a width larger than the height of the accumulated coins is nipped by three packaging rollers (not shown) and rotated,
The accumulated coins are supplied by a packaging film supply means (not shown) so as to leave the crimped portions 4 and 5 above and below, and the coins are wound around them. The coin wrapping machine crimps the upper and lower crimping portions 4 and 5 of the packaging film 3, and includes an upper crimping claw 6 and a lower crimping claw 7 for packaging the accumulated coin 1 with the packaging film 3 in a roll shape. The upper caulking claw 6 and the lower caulking claw 7 are fixed to one ends of an upper arm 8 and a lower arm 9 extending in the horizontal direction, respectively. The upper arm 8 and the lower arm 9 are supported in the vicinity of the other ends by the guide rods 10 and 11 so as to be movable in the vertical direction, that is, to be able to approach or separate from each other.

A rack 12 extending vertically is fixed to the upper arm 8 to which the upper crimping claw 6 is fixed, while a rack 12 is fixed to the lower arm 9 to which the lower crimping claw 7 is fixed.
A pinion 13 that engages with is rotatably attached to form a rack and pinion mechanism. An absolute type rotary encoder 14 is connected to the pinion 13. Reference numeral 15 is a guide roller for guiding the rack 12 to ensure the engagement between the rack 12 and the pinion 13. The upper arm 8 and the lower arm 9 are connected by a spring 22 wound around pulleys 20 and 21, and the upper arm 8 is urged downward and the lower arm 9 is urged upward by the spring 22. ing. On the lower surface of the upper arm 8 in the vicinity of the guide rods 10 and 11, a roller 32 attached to the tip of an upper swing arm 31 capable of swinging around a shaft 30 in a vertical plane is in contact, so that the upper swing is performed. A cam follower 33 is rotatably supported at a substantially intermediate portion between the shaft 30 of the arm 31 and the roller 32. On the other hand, the guide rods 10 and 1 of the lower arm 9
On the upper surface in the vicinity of 1, a roller 37 attached to the tip of a lower swing arm 36 that can swing in a vertical plane around the shaft 30.
And a cam follower 38 is rotatably supported at a substantially intermediate portion between the shaft 35 of the lower swing arm 36 and the roller 37.

The cam follower 33 of the upper swing arm 31
Is in contact with a cam lobe of a first cam 41 rotatable about a cam shaft 40, and a cam follower 38 of the lower swing arm 36 is a second follower rotatable about a cam shaft 40.
The first cam 41 and the second cam are brought into contact with the cam lobes of the cam 42.
The cams 42 are connected to each other so as to rotate as a unit. The cam profiles of the first cam 41 and the second cam 42 are located at positions separated from each other by 180 degrees, and
The cam follower 33 of the upper swing arm 31 has a cam lobe with a maximum distance from 0 and a cam lobe with a minimum distance.
When the cam follower 38 of the lower swing arm 36 is in contact with the cam lobe having the maximum distance from the cam shaft 40, the upper caulking pawl 6 is at the uppermost position, and the caulking pawl 7 is at the lowermost position, that is, The cam followers 33 of the upper swing arm 31 and the lower swing arm 3 are located at the respective retracted positions.
When the cam follower 38 of No. 6 is in contact with the cam lobe with the minimum distance from the cam shaft 40, the upper crimping claw 6 is set to the lowermost position and the lower crimping claw 7 is set to the uppermost position. ing.

Here, the lowermost position of the upper crimping claw 6 and the uppermost position of the lower crimping claw 7 are upwardly crimped when a coin 1 in which a predetermined number of coins of a denomination having a minimum thickness are stacked is packed. The former and the latter are set so that the former and the latter are located above and below the position where the stacked coins 1 can be held. That is, when the upper crimping claw 6 and the lower crimping claw 7 hold the stacked coins to be packed, that is, when the upper crimping claw 6 and the lower crimping claw 7 reach the crimping position, the normal state is obtained. Then, although the upper crimping claw 6 does not descend further and the lower crimping claw 7 does not rise further, for some reason, one of the upper crimping claw 6 and the lower crimping claw 7 is in the predetermined position. When it does not move to the upper side, the other caulking claw further moves, so that the upper caulking claw 6 and the lower caulking claw 7 are moved.
Thus, the stacked coins can be sandwiched and the excess or deficiency of the stacked coins 1 to be wrapped can be reliably detected.

Therefore, in the normal state, the upper swing arm 3
Before the cam follower 33 of 1 and the cam follower 38 of the lower swing arm 36 come into contact with the cam lobe with the minimum distance from the cam shaft 40, the upper crimping claw 6 is placed on the upper surface of the uppermost coin of the coins to be packed, and , The lower crimping claw 7 abuts on the lower surface of the lowermost coin of the integrated coin to be packed, respectively, and as a result, the upper crimping claw 6 and the lower crimping claw 7 and the upper arm 8 are provided.
Further, the lower arm 9 does not move any further, and when the first cam 41 and the second cam 42 further rotate, the cam follower 33 of the upper swing arm 31 contacts the cam lobe of the first cam 41, but the roller 32 Is separated from the lower surface of the upper arm 8, while the roller 37 of the lower swing arm 36 is in contact with the upper surface of the lower arm 9, but the cam follower 38
Is separated from the cam lobe of the second cam 42, the engagement of the first cam 41 and the upper arm 8 via the upper swing arm 31, and the lower swing arm of the second cam 42 and the lower arm 9. The engagement via 36 is designed to be released.

A disc 45 is provided coaxially with the cam shaft 40 so as to be rotatable together with the upper caulking claw cam 41 and the lower caulking claw cam 42 and having a light transmitting hole 46 formed therein. Further, photosensors 47 and 48 each including a light emitting element and a light receiving element are provided. Photo sensor 4
7 indicates that when the cam follower 33 of the upper swing arm 31 and the cam follower 38 of the lower swing arm 36 are in contact with the cam lobe of the first cam 41 and the second cam 42 that is the largest distance from the cam shaft 40, The photo sensor 48 is arranged at a position where the light receiving element can receive the light emitted from the light emitting element through the light transmitting hole 46. Further, the photo sensor 48 has the cam follower 33 of the upper swing arm 31 and the cam shaft of the first cam 41. 40
When it is in contact with the cam lobe with the minimum distance from
The light emitted from the light emitting element is arranged at a position where the light receiving element can receive the light through the light transmitting hole 46.
5 are provided at positions separated from each other by 180 degrees with respect to the rotation direction.

Therefore, the photo sensor 47 can detect that the upper crimp claw 6 and the lower crimp claw 7 are located at the retracted position, and the cam follower 33 of the upper swing arm 31 can be detected. When the first cam 41 is in contact with the cam lobe with the minimum distance from the cam shaft 40, the upper crimp claw 6 should be wrapped on the upper surface of the uppermost coin of the coins to be wrapped, and the lower crimp claw 7 should be wrapped. Since the upper crimping claw 6 and the lower crimping claw 7 are located at the crimping positions, that is, the upper crimping claw 6 and the lower crimping claw 7 are in contact with the lower surface of the lowest coin of the accumulated coins, respectively. It can be detected that the lower crimp claw 7 is located at the crimp position.

As described above, the upper crimping claw 6 and the lower crimping claw 7 are the first when the one roll-shaped integrated coin 1 is packaged.
When the cam 41 and the second cam 42 rotate once, the cam 41 and the second cam 42 are moved from the retracted position to the caulking position, and further returned to the retracted position. As a result, the upper arm 8 and the lower arm 9 are also vertically moved. Move in the direction. As a result, the rack 12 fixed to the upper arm 8 causes the pinion 13 rotatably attached to the lower arm 9 to rotate by an amount corresponding to the amount of vertical movement of the upper caulking claw 6 and the lower caulking claw 7. It is supposed to be done. Here, since the absolute type rotary encoder 14 connected to the pinion 13 can output the encoded absolute position data of a predetermined number of bits according to the rotational position, the rotary encoder 14 Based on the output absolute position data, the vertical movement amount of the upper crimp claw 6 and the lower crimp claw 7 can be detected. For example, when using a pinion 13 having a diameter of 24 mm and an 8-bit rotary encoder 14,
It is possible to obtain absolute position data with a resolution of 0.29 mm.

FIG. 2 is a diagram showing the configuration of the control system of the coin wrapping machine according to the present embodiment. The rotary encoder 14, the coin wrapping control mechanism 50, the number-of-processes counting means 51, the denomination-based reference data storage 52, and the allowance. Value storage unit 53, data calculation unit 54, within-permissible comparison determination unit 55, detection data storage unit 5
6. It comprises an excess / deficiency detection control unit 57.

The coin wrapping control mechanism 50 controls the entire coin wrapping machine and includes the normal coin wrapping process described above, detection of the presence of unwrapped coins, and excess or deficiency of a predetermined number of wrapping coins (for example, 50 pcs.). Occurrence of abnormal number of packaging coins (roll clear), counting the number of roll clears (including sporadic ones), counting the number of continuous roll clears, alarm control that generates an alarm, detection of opening and closing the machine door, An instruction to start the above-described tightening data correction (reference data correction) operation is given. The processing number counting means 5
1 is the number of packages when the coin packaging control mechanism 50 enters the crimping data correction operation and performs the crimping data correction operation based on the detection data (cumulative height) of a predetermined number (for example, 4) of packaging coins. Is designed to count. The denomination-specific reference data storage unit 52 stores reference data for denominations for comparing and determining the detection data (denomination data) detected by the rotary encoder 14.

The permissible value storage unit 53 is adapted to store permissible range data when comparing the detected data with the reference data. In the present embodiment, there are two types of the allowable range, a range d1 and a range d2, and the range d1 is compared at the time of normal determination (see step SA4 in FIG. 3) and the second and subsequent comparison determinations of the crimping data correction operation. It is used at the time (see FIG. 4), and when it is converted to a narrow range (for example, when converted to mm,
(± 0.75 mm), and the range d2 is used for the first comparison judgment of the crimping data correction operation, and is a wider range (for example, when converted to mm, ±
2.5 mm). The reason why the wider range is set is to take into consideration the possibility that the disposition position of the caulking claw is displaced due to replacement or adjustment of the caulking claw.

The data calculation unit 54 calculates various data related to coin packaging control, and sets the reference range by adding the allowable range to the reference data, calculates the difference between the data, and calculates the data. The average value is calculated. The within-permissible comparison determination unit 55 is configured to determine whether or not the detection data is within the reference range (permissible range) set by the data calculation unit 54.
The detection data storage unit 56 includes the rotary encoder 14
The detection data (absolute position data) output from is stored. The excess / deficiency detection control unit 57 determines whether or not the number of packaged coins is a predetermined number, and determines whether or not the number of coins is normal, and crimps after a continuous abnormality in which the detected data continuously exceeds the allowable range. The operation control such as data correction is performed.

By the way, in the coin packaging machine of this embodiment, as described above, the detection data of the cumulative height of the packaging coins (the amount of movement of the caulking claws detected by the rotary encoder 14) continues within the allowable range with respect to the reference data. If it exceeds the limit, the reference data is corrected based on the detected data, and the basis for correcting the reference data when, for example, three or more consecutive abnormalities occur is as follows. That is, if the first packaging coin is 49 coins, the
One coin is added to the next accumulated coin and the second packed coin is 51
Although there are many patterns of single-packed coins, if the third packaged coin is abnormal, the reference data is modified from the viewpoint that it is not a problem of merely increasing or decreasing the number of coins. In this case, it is possible to determine up to the number of packages based on the detection data. Therefore, when the first packaging coin is 49 coins and the second packaging coin is 49 coins, and when the first packaging coin is 51 coins, It is also possible to immediately proceed to the reference data correction operation when the first wrapped coin is 51 coins.

Next, the "normal excess / shortage detection operation" and the "operation when the crimping data is corrected" in the coin wrapping machine of the present embodiment configured as described above will be described with reference to FIGS.

"Normal Over / Under Detection Operation" (FIG. 3) In the processing of FIG. 3, the number of roll clear operations (including one-time operation) is counted, and the clear box for storing the removed abnormal packaging coins is full. If (the number of times of clearing is M times), the alarm process is performed to prompt the operator to collect coins in the clear box. In addition, the number of continuous clearing operations is counted, and when the number of continuous clearing operations reaches N times (for example, 2 times), it is determined that the position of the crimping claw is deviated from the regular position, and the packaging coin removed in the clear box. In order to let the operator confirm what kind of state is in, the process shifts to alarm processing. When the alarm process is completed, the crimping data correction operation is immediately started, and a plurality of packaged coins (the number is four in this embodiment, however, the larger the number, the better) will be processed thereafter. The detection data of is used for correcting the reference data. The details of the normal excess / deficiency detection operation will be described below.

When the coin wrapping unit of the coin wrapping machine receives a predetermined number of coins of the denomination to be wrapped from the coin judging and counting unit (step SA1), the wrapping film is wound around the accumulated coins by the above-mentioned wrapping operation. (Step SA2), the upper and lower crimping portions of the packaging film are crimped by the upper crimping claw 6 and the lower crimping claw 7 (step SA3). Upon completion of the crimping operation, it is determined whether or not the predetermined number of packaging coins have been normally crimped (step SA4). If the predetermined number of packaging coins have not been crimped, step S described later is performed.
On the other hand, when the process proceeds to the processing of A10 and thereafter, when a predetermined number of the packed coins are crimped, the packed coins are discharged to the normal packed coin storage box (step SA5). Next, after resetting the count value of the continuous clear operation (step SA
6), it is determined whether or not there are unwrapped coins (step S
A7). If there are unwrapped coins, the process returns to step SA1 to wait for the packed denomination coins, while if there are no unwrapped coins, it is determined whether the count value of the clearing process has been reset (step SA8) and reset. If yes, the present process is terminated, while if not reset, an alarm is activated (step SA9).

On the other hand, if it is determined in step SA4 that the predetermined number of packaged coins have not been crimped, an abnormal number of packaged coins are removed (roll clear) (step SA10), and the number of roll clearing operations ( (Including a one-time event) is counted up (step SA11). Then, it is determined whether or not the number of roll clear operations reaches a predetermined number M, that is, whether or not the clear box for storing the rejected abnormal packaging coins is full (step S
A12) If the clear box is not full, the process proceeds to step SA19 and subsequent steps described later, while if the clear box is full, the alarm is stopped (step SA13), and then the door of the machine is opened. It is determined whether it has been done (step SA14). When the door is not opened, the process returns to step SA13, while when the door is opened, the operator takes out the clear roll from the clear box (step SA15). Next, it is determined whether the door is closed (step SA16), and when the door is closed, the alarm is released (step SA1).
7) After resetting the number of roll clear operations (step SA18), the process returns to step SA1.

On the other hand, if the clear box is not full in the judgment at step SA12, the number of continuous clear operations is counted (step SA19), and the number of continuous clear operations is N times (for example, twice in this embodiment). ) Has been reached (step SA20), and if the number of consecutive clear operations has not reached N times, the process returns to step SA1 while the number of consecutive clear operations reaches N times. Judges that the position of the caulking claw is deviated from the regular position, and after stopping the alarm (step SA21),
It is determined whether or not the door is opened (step SA2
2). When the door is not opened, the above step SA2
On the other hand, when the door is opened while returning to step 1, the operator takes out the clear roll from the clear box (step S
A23). Next, it is determined whether or not the door is closed (step SA24), the alarm is released when the door is closed (step SA25), the number of continuous clearing operations is reset (step SA26), and the caulking data is corrected. After activating the flowchart (Fig. 4) for use (step SA2
7) Then, the process returns to step SA1.

"Operation when the caulking data is corrected" (FIG. 4) In the process of FIG. 4, the caulking data is corrected by, for example, a denomination "1".
It is performed over four "circle" packages, but the first one is performed in a wide range by adding the range d2 to the reference data, and the second and subsequent ones are performed in a narrow range by adding the range d1 to the reference data. There is. When the detection data of the packaged coin exceeds the reference range, the number of processed pieces is subtracted by "1", the detection data of the packaged coin is reset, and the data is deleted from the data. When rewriting the reference data in the denomination-based reference data storage unit 52, the difference between the old and new reference data is calculated, and the difference data is output, so that the data written in other denomination data that is not being processed. Subtract the difference data from
Other denomination data are also rewritten. This makes it possible to collectively correct all the denominations of the reference data that has been misaligned due to the position of the caulking claw deviating from the normal position. In addition, other denominations other than denomination "1 yen" (5 yen to 5
The flowchart for rewriting the data of (00 yen) is omitted. Hereinafter, the details of the operation when correcting the crimping data will be described.

When the crimping operation of the wrapping coin of denomination "1 yen" is performed after resetting the count value of the processing number counting means 51 for counting the number of wrappings in the crimping data correction operation (step SB1). (Step SB2) counts up the number of the processed coins (step SB3). 1
When the detection data A1 of the actual packaged coin is fetched (step SB4), the range d2 is added to the past denomination standard data X1 stored in the denomination standard data storage unit 52 (step SB5). In this case, in each denomination area of the denomination reference data storage unit 52, as shown in FIG. 5, past denomination reference data (X1 to X6: average value of 1-yen coin to 500-yen coin detection data), The allowable values d1 and d2 are written. Next, it is determined whether or not the first data A1 is within the allowable range, that is, whether or not X1-d2 <A1 <X1 + d2 is satisfied (step SB6). If the first data A1 is within the allowable range, the first data A1 is determined. Is written in the 1-yen denomination area of the denomination-based reference data storage unit 52 as the reference data B1 (step SB7). Further, the difference between the past reference data X1 and the new reference data B1, that is, X1−B1 = Y1 is calculated, and the calculated data Y1 is output (step SB8).
Then, by subtracting the calculated data Y1 from the reference data of other denominations to correct the reference data (see FIG. 6), other denomination areas of the denomination-based reference data storage unit 52 are also rewritten. On the other hand, if it is determined in step SB6 that the first data A1 is not within the permissible range, the count value by the processing number counting means 51 is counted down (step S6).
B9) After resetting the first data A1 (step SB10), the process returns to step SB2.

Then, the above-mentioned step SB8, step SB17 described later, or step SB19 described later,
Alternatively, after completion of step SB24 described later, step SB26 described later, step SB30 described later, or step SB32 described later, it is determined whether or not the crimping operation of the packaging coin of the denomination “1 yen” has been performed. (Step SB
11) If the caulking operation is performed, the above step SB3
On the other hand, when the caulking operation is not performed while returning to the process of step 1, it is determined whether the denomination is switched from "1 yen" to another denomination and the caulking data is corrected (step SB12). When the denomination switching is not performed, the process returns to the determination of step SB11, while when the denomination switching is performed, the process is finished.

Further, the detection data A2 of the second wrapped coin
When is taken in (step SB13), the range d1 is added to the reference data B1 (step SB14). Next, it is determined whether or not the second data A2 is within the allowable range, that is, whether or not B1-d1 <A2 <B1 + d2 is satisfied (step SB15). If the second data A2 is within the allowable range, the first data A1 is determined. The average value of the second data A2 is calculated, and the calculated average value is written as reference data B2 in the 1-yen denomination area of the denomination-based reference data storage unit 52 (step SB16). Further, the reference data B1 and the reference data B2
Is calculated, that is, B1-B2 = Y2 is calculated, and the calculated data Y2 is output (step SB17). Then, by subtracting the calculated data Y2 from the reference data of other denominations to correct the reference data (see FIG. 7), the other denomination areas of the denomination-based reference data storage unit 52 are also rewritten. After that, the processing shifts to the determination in step SB11. On the other hand, when the second data A2 is not within the allowable range in the determination of step SB15, the count value by the processing number counting means 51 is counted down (step SB18), and after the second data A2 is reset (step SB19), The process moves to the determination in step SB11.

Further, the detection data A3 of the third wrapped coin
When is taken in (step SB20), the range d1 is added to the reference data B2 (step SB21). Then, it is determined whether or not the third data A3 is within the allowable range, that is, whether or not B2-d1 <A3 <B2 + d1 is satisfied (step SB22). If the third data A3 is within the allowable range, the first data A1 is determined. Second data A2, third data A
The average value of 3 is calculated, and the calculated average value is used as the reference data B.
The value of 3 is written in the 1-yen denomination area of the denomination-based reference data storage unit 52 (step SB23). Further, the difference between the old and new reference data B2 and B3, that is, B2-B3 = Y3, is calculated,
The calculated data Y3 is output (step SB24). Then, by correcting the reference data of another denomination based on the calculated data Y3 (see FIG. 8), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. After that, the processing shifts to the determination in step SB11. On the other hand, if it is determined in step SB22 that the third data A3 is not within the allowable range, the count value by the processing number counting means 51 is counted down (step SB25), and the third data A3.
After resetting (step SB26), the process shifts to the determination in step SB11.

Further, the detection data A4 of the fourth wrapped coin
Is taken in, the range d1 is added to the reference data B3 (step SB27). Next, whether or not the fourth data A4 is within the allowable range, that is, B3-d1 <A4 <B
It is determined whether or not 3 + d1 is established (step SB2
8) If it is within the allowable range, the average value of the first data A1, the second data A2, the third data A3, and the fourth data A4 is calculated, and the calculated average value is used as the reference data B4 for the gold type reference data. Write in the 1-yen denomination area of the storage unit 52 (step SB29). Furthermore, the old and new reference data B
The difference between 3 and B4, that is, B3-B4 = Y4 is calculated, and the calculated data Y4 is output (step SB30). Then, by correcting the reference data of another denomination based on the calculated data Y4 (see FIG. 9), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. After that, the processing shifts to the determination in step SB11. On the other hand, if the fourth data A4 is not within the allowable range in the determination at step SB28, the count value by the processing number counting means 51 is counted down (step SB31) and the fourth data A4.
After resetting (step SB32), the process shifts to the determination of step SB11.

As described above, according to the present invention, a packaging film having a width larger than the height of the accumulated coins is provided around a predetermined number of accumulated coins so that the crimped portions remain above and below the accumulated coins. In a coin wrapping machine that forms a wrapping coin by sandwiching an integrated coin by a pair of crimping claws that are movable so as to be close to each other after winding and crimping the crimped portion, Detecting means for detecting the cumulative height as the moving amount of the crimping claw, storage means for storing in advance reference data corresponding to the cumulative height of a normal number of wrapped coins packed in a predetermined number, and detection detected by the detecting means. The data is compared with the reference data stored in the storage means, and when the detection data exceeds the allowable range for the reference data at least twice in succession, the reference data in the storage means is based on the detection data. Because a configuration having a excess or deficiency detection control means for modifying you are, can be obtained the following effects. If the detection data of the cumulative height of the packaging coins exceeds the permissible range for the reference data at least twice in succession, the position of the crimping claw may be changed due to some cause such as replacement or adjustment of the crimping claw. Since it is determined that there is a deviation, and the reference data is then corrected based on the detected data, it is always possible to accurately determine and process whether there is excess or deficiency in the packaging coin. As a result, as in the conventional case, when the position of the crimping claw is deviated from the normal position, a normal packaging coin that has been packaged a prescribed number of coins despite being packaged with a prescribed number of coins is mistaken as an abnormal packaging coin. It is possible to eliminate the determination problem.
