DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for detecting an excess or deficiency of a coin wrapping machine which prevents a problem that a predetermined number of normal wrapped coins are erroneously determined as abnormal wrapped coins.

[0002]

2. Description of the Related Art Conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 3-612, when a wrapping paper is wound around a predetermined number of coins (for example, 50 coins) by a coin wrapping machine and wrapped, some sort of operation is performed. A coin excess / deficiency detection device that prevents a predetermined number of wrapped coins (for example, 49 wraps, 51 wraps, etc.) from being released from a chute as a normal wrapped coin wrapped in the predetermined number of sheets due to the above reason. Is provided. In the device described in the publication, after wrapping the wrapping paper around the stacked coins,
The amount of movement of the caulking claw for caulking the upper and lower edges of the wrapping paper close to the upper and lower ends of the coin is detected by a rotary encoder, and the detected value of the movement is compared with a previously stored reference value. Thus, whether or not a predetermined number of coins are wrapped is detected.

[0003]

However, in the conventional coin wrapping machine described above, when a caulking claw that has become unusable due to, for example, abrasion is replaced with a new caulking claw, the replaced caulking claw is replaced. The arrangement position of the claws may be slightly different from the normal position. When the disposition position of the caulking claw deviates from the normal position in this way, the detection value of the amount of movement of the caulking claw by the rotary encoder is within an allowable range with respect to a reference value, even though a predetermined number of coins are packed. As a result, there is a problem that a normal wrapped coin wrapped in a predetermined number is erroneously determined as an abnormal wrapped coin.

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

[0005]

In order to achieve the above-mentioned object, the present invention relates to a method of forming a wrapping film having a width larger than the height of a stack of coins around a predetermined number of stacks of coins, In a coin wrapping machine which forms a wrapped coin by winding a stack of coins by a pair of caulking claws made movable so as to be close to each other after being wound so as to remain, and caulking the caulked portion. Detecting means for detecting the cumulative height of the wrapped coins as the amount of movement of the caulking claw; storage means for storing in advance reference data corresponding to the cumulative height of normal wrapped coins wrapped in a predetermined number of coins; Is compared with the reference data stored in the storage means, and the detected data is within an allowable range for the reference data.
The excess or deficiency detection control means that corrects the reference data in the storage means based on the detection data when the value exceeds the upper limit or lower limit side at least two times consecutively.

[0006]

According to the present invention, the detection data of the accumulated height of the wrapped coins is set such that the allowable range with respect to the reference data is on the upper side or
If it exceeds the lower limit continuously at least twice or more, it is determined that the position of the caulking claw has shifted due to some cause, for example, replacement or adjustment of the caulking claw, and thereafter, the reference is determined based on the detection data. In order to correct the data, it is always possible to accurately determine and process whether or not there is no excess or deficiency in the wrapped coins.
As a result, when the disposition position of the caulking claw is deviated from the normal position as in the related art, even though a predetermined number of coins are wrapped, a normal wrapped coin wrapped by the predetermined number is mistaken as an abnormal wrapped coin. The problem of the determination can be solved.

[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 the present embodiment. The detection data of the accumulated height of the wrapped coins (the amount of movement of the caulking claw detected by a rotary encoder described later) indicates an allowable range with respect to the reference data. If it exceeds continuously, for example, it is determined that the position of the caulking pawl has shifted due to some reason such as replacement or adjustment of the caulking claw, and thereafter, the reference data is corrected based on the detection data. In addition, a problem of erroneously determining a normal wrapped coin wrapped in a predetermined number of sheets as an abnormal wrapped coin as in the related art is prevented.

A roll discriminating / counting unit (not shown) discriminates and counts the authenticity and denomination, sorts only coins of the denomination to be packed, and sends a predetermined number of coins to a coin stacking unit (not shown) to accumulate the rolls. The coin 1 is placed on a support bar 2 and transferred to a packaging position of a coin packaging unit. Thereafter, the film 3 is sandwiched and rotated by three wrapping rollers (not shown), and the wrapping film 3 having a width larger than the height of the stacked coins is obtained.
The coins are supplied by a packaging film supply means (not shown) so as to leave the crimped portions 4 and 5 above and below the stacked coins, and are wound around the coins. The coin wrapping machine crimps the upper and lower crimping portions 4 and 5 of the packaging film 3 to form the upper crimping claw 6 and the lower crimping claw 7 for packing the accumulated coins 1 in a roll shape with the packaging film 3. The upper caulking claw 6 and the lower caulking claw 7 are fixed to one end 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 by guide rods 10 and 11 in the vicinity of the other end so as to be vertically movable, that is, to be able to approach or separate from each other.

A vertically extending rack 12 is fixed to the upper arm 8 to which the upper caulking claw 6 is fixed, while the rack 12 is fixed to the lower arm 9 to which the lower caulking claw 7 is fixed.
Is rotatably mounted to form a rack-and-pinion mechanism. An absolute root type rotary encoder 14 is connected to the pinion 13. Reference numeral 15 denotes a guide roller that guides 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. A roller 32 attached to the tip of an upper swing arm 31 that can swing about a shaft 30 in a vertical plane is in contact with the lower surface of the upper arm 8 near the guide rods 10 and 11, and the upper swing 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, 1
1, a roller 37 attached to the tip of a lower swing arm 36 that can swing in a vertical plane around the axis 30
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
Abuts against a cam lobe of a first cam 41 rotatable about a cam shaft 40, and a cam follower 38 of a lower swing arm 36 rotates a second cam rotatable about the cam shaft 40.
The first cam 41 and the second cam 41
The cams 42 are connected to each other and rotate as a unit. The cam profiles of the first cam 41 and the second cam 42 are located at positions 180 degrees apart from each other.
The cam follower 33 of the upper swing arm 31 has a cam lobe having the largest distance from 0 and a cam lobe having the smallest distance.
When the cam follower 38 of the lower swing arm 36 is in contact with the cam lobe having the largest distance from the cam shaft 40, the upper caulking claw 6 is at the uppermost position, and the caulking claw 7 is at the lowermost position, that is, The cam follower 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 FIG. 6 is in contact with the cam lobe whose distance from the camshaft 40 is the smallest, the upper caulking claw 6 is set at the lowest position, and the lower caulking claw 7 is set at the highest position. ing.

Here, the lowermost position of the upper caulking claw 6 and the uppermost position of the lower caulking claw 7 are set at the upper caulking when coins of a predetermined number of coins having a minimum thickness are packed. The former is set to be further lower and the latter is set to be further higher than the position where the claw 6 and the lower caulking claw 7 can pinch the stacked coins 1. That is, when the upper caulking claw 6 and the lower caulking claw 7 hold the stacked coins to be packed, that is, when the upper caulking claw 6 and the lower caulking claw 7 reach the caulking position, the normal state is attained. In this case, the upper caulking claw 6 does not move down any further, and the lower caulking claw 7 does not move up any further. However, for some reason, one of the upper caulking claw 6 and the lower caulking claw 7 is in a predetermined position. If it does not move, the other caulking claw further moves, thereby causing the upper caulking claw 6 and the lower caulking claw 7 to move.
Thus, the accumulated coins can be pinched and the excess or deficiency of the accumulated coins 1 to be packed can be reliably detected.

Therefore, in the normal state, the upper swing arm 3
Before the first cam follower 33 and the cam follower 38 of the lower swing arm 36 come into contact with the cam lobe having the smallest distance from the cam shaft 40, the upper caulking claw 6 is placed on the upper surface of the top coin of the stacked coins to be wrapped, and , The lower caulking pawl 7 abuts against the lower surface of the lowermost coin of the stack of coins to be packed, so that the upper caulking pawl 6, the lower caulking pawl 7, and the upper arm 8
When the lower arm 9 does not move any further and the first cam 41 and the second cam 42 rotate further, the cam follower 33 of the upper swing arm 31 is in contact with 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 first cam 41 and the upper arm 8 are engaged via the upper swing arm 31, and the second cam 42 and the lower arm 9 are swinged by the lower swing arm. The engagement via 36 is released.

A disk 45 having a light transmitting hole 46 is provided coaxially with the cam shaft 40 and rotatable together with the upper caulking pawl cam 41 and the lower caulking pawl cam 42. Photosensors 47 and 48 each including a light emitting element and a light receiving element are provided. Photo sensor 4
7, 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 lobes whose distance from the cam shaft 40 of the first cam 41 and the second cam 42 is the largest. The light emitted from the light emitting element is disposed at a position where the light receiving element can receive the light through the light transmitting hole 46. The photo sensor 48 is configured such that the cam follower 33 of the upper swing arm 31 is a cam shaft of the first cam 41. 40
When it is in contact with the smallest cam lobe,
The light emitted from the light emitting element is disposed at a position where the light receiving element can receive the light through the light transmitting hole 46.
5 are provided at positions 180 degrees apart from each other in the rotation direction.

Therefore, the photo sensor 47 can detect that the upper caulking claw 6 and the lower caulking claw 7 are located at the retracted position, and the cam follower 33 of the upper swing arm 31 can When the distance between the first cam 41 and the cam shaft 40 is in contact with the smallest cam lobe, the upper caulking claw 6 must be always on the upper surface of the uppermost coin of the stacked coins to be wrapped, and the lower caulking claw 7 must be wrapped. Since the upper crimping claw 6 and the lower crimping claw 7 are located at the crimping positions, that is, in contact with the lower surface of the lowermost coin of the stacking coin, the upper crimping claw 6 and the It can be detected that the lower caulking claw 7 is located at the caulking position.

As described above, the upper caulking claw 6 and the lower caulking claw 7 are used to wrap one roll-shaped coin 1 in the first direction.
When the cam 41 and the second cam 42 make one rotation, they are moved from the retracted position to the caulking position, and then returned to the retracted position. Accordingly, the upper arm 8 and the lower arm 9 are also moved up and down. Move in the direction. As a result, the pinion 13 rotatably attached to the lower arm 9 by the rack 12 fixed to the upper arm 8 rotates by an amount corresponding to the vertical movement of the upper caulking claw 6 and the lower caulking claw 7. It is made to be made. Here, the absolute type rotary encoder 14 connected to the pinion 13 can output coded absolute position data of a predetermined number of bits in accordance with its rotational position. Based on the output absolute position data, the amount of vertical movement of the upper caulking claw 6 and the lower caulking claw 7 can be detected. For example, when a pinion 13 having a diameter of 24 mm and an 8-bit rotary encoder 14 are used,
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 of the present embodiment. The rotary encoder 14, the coin wrapping control mechanism 50, the number-of-processes counting means 51, the denomination reference data storage unit 52, Value storage unit 53, data operation unit 54, acceptable comparison determination unit 55, detection data storage unit 5
6. It is composed of an excess / deficiency detection control section 57.

The coin wrapping control mechanism 50 controls the entire coin wrapping machine, and performs the normal coin wrapping processing described above, detects the presence / absence of unwrapped coins, and sets a predetermined number of wrapped sheets (for example, 50). Elimination of abnormally wrapped coins (roll clear), counting the number of roll clears (including sporadic ones), counting the number of continuous roll clears, alarm control to generate an alarm, detection of the opening and closing of the body door, An instruction to start the above-described caulking data correction (reference data correction) operation or the like is issued. The processing number counting means 5
1 indicates the number of wraps when the coin wrapping control mechanism 50 starts the caulking data correcting operation and performs the caulking data correcting operation based on the detection data (accumulated height) of a predetermined number (for example, four) of wrapped coins. Is counted. The denomination reference data storage unit 52 stores, for each denomination, reference data for comparing and determining data detected by the rotary encoder 14 (denomination data).

The permissible value storage section 53 stores 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 determined at the time of normal determination (see step SA4 in FIG. 3), and the second and subsequent comparison determinations of the caulking data correction operation. Time (see FIG. 4), and is used in a narrow range (for example, when converted to mm,
± 0.75 mm), and the range d2 is used at the time of the first comparison determination of the caulking data correcting operation, and is set to a wider range (for example, ± mm when converted to mm).
2.5 mm). The reason why the wider range is set is to take into account the possibility that the arrangement position of the caulking claw is shifted due to replacement / adjustment of the caulking claw.

The data calculation section 54 calculates various data related to coin packaging control. The data calculation section 54 sets a reference range by adding an allowable range to the reference data, calculates a difference between the data, and calculates the data. Calculation of an average value and the like are performed. The in-permissible comparison determination unit 55 determines 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 a normal number of wrapped coins to determine whether or not the number of wrapped wrapped coins is a predetermined number, and caulking after a continuous abnormality in which the detection data continuously exceeds an allowable range. Operation control such as data correction is performed.

By the way, in the coin wrapping machine of the present embodiment, as described above, the detection data of the accumulated height of the wrapped coins (the amount of movement of the caulking claw detected by the rotary encoder 14) continuously falls within the allowable range with respect to the reference data. If it exceeds the limit, the reference data is corrected based on the detection data thereafter. For example, the grounds for correcting the reference data when three or more consecutive abnormalities occur are as follows. That is, if the first wrapped coin is wrapped in 49 sheets, the missing 1
Is added to the next coin and the second wrapped coin is 51
There are a lot of patterns to be wrapped, but if the third wrapped coin is abnormal, the reference data is modified from the viewpoint that it is not merely a matter of increasing or decreasing the number of coins. In this case, it is possible to determine up to the number of wrapped sheets based on the detection data, so that the first wrapped coin is 49 sheets and the second wrapped coin is 49 sheets, and the first wrapped coin is 51 sheets and 2 sheets. It is possible to immediately proceed to the reference data correcting operation when the number of the wrapped coins is 51.

Next, the "normal operation for detecting excess or deficiency" and the "operation at the time of correcting caulking data" in the coin wrapping machine of the present embodiment configured as described above will be described with reference to FIGS.

"Normal excess / deficiency detection operation" (FIG. 3) In the process of FIG. 3, the number of roll clear operations (including one-off operations) is counted, and the clear box for storing the removed abnormally wrapped coins is full. (When the number of clears is M), the process shifts to an alarm process in order 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 consecutive clearing operations reaches N times (for example, two times), it is determined that the position of the caulking claw has deviated from the normal position, and the wrapped coin removed in the clear box. In order to make the operator confirm the state of the alarm, the process proceeds to an alarm process. When the alarm processing is completed, the caulking data correction operation is started immediately, and thereafter, a plurality of wrapped coins (the number is four in this embodiment, of course, the larger the number, the better). The detected data is used for correcting reference data. Hereinafter, the details of the normal excess / deficiency detection operation will be described.

When a predetermined number of coins of a denomination to be wrapped are received from the coin determination and counting unit (step SA1), the coin wrapping unit of the coin wrapping machine winds the wrapping film around the stacked coins by the above-described wrapping operation. (Step SA2), the upper and lower caulking portions 6 and 7 are caulked at the upper and lower caulking portions of the packaging film (step SA3). When the caulking operation is completed, it is determined whether or not the predetermined number of wrapped coins have been properly caulked (step SA4).
On the other hand, when the process proceeds to A10 and subsequent steps, if the wrapped coins are swaged by a predetermined number, the wrapped coins are discharged to the normal wrapped 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 is an unwrapped coin (step S)
A7). If there are unwrapped coins, the flow returns to the process of step SA1 to wait for the wrapped coins, while if there are no unwrapped coins, it is determined whether or not the count value of the clearing process has been reset (step SA8) and reset. If this is the case, the process is terminated, while if it is not reset, an alarm is activated (step SA9).

On the other hand, if it is determined in step SA4 that the wrapped coins have not been swaged by the predetermined number, a process of eliminating the abnormal number of wrapped coins (roll clear) is performed (step SA10), and the number of roll clear operations (step SA10) (Including sporadic ones) is counted up (step SA11). Next, it is determined whether or not the number of roll clear operations has reached a predetermined number of M times, that is, whether or not the clear box for storing the removed abnormally wrapped coins is full (step S).
A12) If the clear box is not full, the process proceeds to the processing from step SA19 to be described later. If the clear box is full, the alarm is stopped (step SA13), and the door of the machine is opened. It is determined whether or not the operation has been performed (step SA14). If the door has not been opened, the process returns to step SA13, while if the door has been opened, the operator removes the clear roll from the clear box (step SA15). Next, it is determined whether or not the door is closed (step SA16). If 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 determination at step SA12, the number of continuous clear operations is counted (step SA19), and the number of continuous clear operations is N (in this embodiment, for example, two). ) Is determined (step SA20). If the number of continuous clear operations has not reached N, the process returns to step SA1. On the other hand, if the number of continuous clear operations has reached N, Is determined that the position of the caulking claw is deviated from the normal position, and after stopping the alarm (step SA21),
It is determined whether the door has been opened (step SA2)
2). If the door is not opened, the above step SA2
When the door is opened while returning to step 1, the operator removes the clear roll from the clear box (step S).
A23). Next, it is determined whether or not the door is closed (step SA24). If the door is closed, the alarm is released (step SA25), the number of continuous clear operations is reset (step SA26), and the caulking data is corrected. (FIG. 4) is started (step SA2).
7), returning to the processing of step SA1.

"Operation at the time of correcting caulking data" (FIG. 4) In the process of FIG.
The process is performed over four wrapped circles. The first process is performed over a wide range obtained by adding the range d2 to the reference data, and the second process is performed over a narrow range obtained by adding the range d1 to the reference data. I have. When the detection data of the wrapped coin exceeds the reference range, the processing number is subtracted by "1", and the detection data of the wrapped coin is reset and deleted from the data. When rewriting the reference data in the denomination reference data storage unit 52, the difference between the old and new reference data is obtained, 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 is also rewritten. Thus, the reference data in which the position of the caulking claw is deviated from the normal position and which is out of order can be collectively corrected for all denominations. In addition, other denominations other than the denomination "1 yen" (5 yen to 5 yen)
The flowchart for rewriting the data of “00 yen” is omitted. Hereinafter, the operation at the time of correcting the caulking data will be described in detail.

Processing for counting the number of wrappings during the caulking data correction operation After resetting the count value of the number-of-packings counting means 51 (step SB1), when the caulking operation of the wrapping coin of denomination "1 yen" is performed. (Step SB2), the number of processed coins is counted up (step SB3). 1
When the detection data A1 of the first wrapped coin is taken in (step SB4), a range d2 is added to the past denomination reference data X1 stored in the denomination reference data storage unit 52 (step SB5). In this case, in each denomination area of the denomination reference data storage unit 52, past denomination reference data (X1 to X6: average value of detection data of 1 yen coin to 500 yen coin) are stored as shown in FIG. The allowable values d1 and d2 have been written. Next, it is determined whether the first data A1 is within the allowable range, that is, whether 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 one-yen denomination area of the denomination reference data storage unit 52 as 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 the other denominations and correcting the reference data (see FIG. 6), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. On the other hand, if the first data A1 is not within the allowable range in the determination at step SB6, the count value of 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.

Next, step SB8, step SB17 described later, or step SB19 described later,
Or, after step SB24 described later, step SB26 described later, step SB30 described later, or step SB32 described later, it is determined whether or not the caulking operation of the denomination “1 yen” wrapped coin has been performed. (Step SB
11) If the caulking operation is performed, the above-described step SB3 is performed.
On the other hand, if the caulking operation is not performed, it is determined whether the denomination is switched from "1 yen" to another denomination and correction of the caulking data is performed (step SB12). When the denomination switching is not performed, the process returns to the determination in step SB11. On the other hand, when the denomination switching is performed, the present process is terminated.

The detection data A2 of the second wrapped coin
Is acquired (step SB13), a 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 the reference data B2 in the one-yen denomination area of the denomination reference data storage unit 52 (step SB16). Further, reference data B1 and reference data B2
, That is, B1-B2 = Y2, and outputs the calculated data Y2 (step SB17). Then, by subtracting the calculated data Y2 from the reference data of other denominations and correcting the reference data (see FIG. 7), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. Thereafter, the process proceeds to the determination at step SB11. On the other hand, if the second data A2 is not within the allowable range in the determination in step SB15, the count value of the processing number counting means 51 is counted down (step SB18), and the second data A2 is reset (step SB19). The process proceeds to the determination in step SB11.

The detection data A3 of the third wrapped coin is
Is acquired (step SB20), a range d1 is added to the reference data B2 (step SB21). Next, 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
3 is calculated, and the calculated average value is used as the reference data B
3 is written in the one-yen denomination area of the denomination reference data storage unit 52 (step SB23). Further, the difference between the new and old reference data B2, B3, that is, B2-B3 = Y3 is calculated,
The calculated data Y3 is output (step SB24). Then, by modifying the reference data of another denomination based on the calculation data Y3 (see FIG. 8), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. Thereafter, the process proceeds to the determination at step SB11. On the other hand, if the third data A3 is not within the allowable range in the determination in step SB22, the count value of the processing line count means 51 is counted down (step SB25).
Is reset (step SB26), and the routine goes to the determination at step SB11.

The detection data A4 of the fourth wrapped coin is
Is acquired, a 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 3 + d1 holds (step SB2).
8) If it is within the allowable range, the average of the first data A1, the second data A2, the third data A3, and the fourth data A4 is calculated, and the calculated average is used as the reference data B4 as the reference data B4. The data is written in the one-yen denomination area of the storage unit 52 (step SB29). Furthermore, the old and new reference data B
The difference between B3 and B4, that is, B3−B4 = Y4, is calculated, and the calculated data Y4 is output (step SB30). Then, by modifying the reference data of another denomination based on the calculation data Y4 (see FIG. 9), the other denomination areas of the denomination reference data storage unit 52 are also rewritten. Thereafter, the process proceeds to the determination at step SB11. On the other hand, if the fourth data A4 is not within the allowable range in the determination in step SB28, the count value of the processing number counting means 51 is counted down (step SB31).
Is reset (step SB32), and the routine goes to the determination at step SB11.

As described above, according to the present invention, a wrapping film having a width larger than the height of the stacked coins is wound around a predetermined number of stacked coins so that caulked portions are left and below the stacked coins. After winding, in a coin wrapping machine that forms a wrapped coin by clamping a stack of coins with a pair of caulking claws that can be moved close to each other and caulking the caulked portion, Detecting means for detecting the cumulative height as the amount of movement of the caulking claw; storing means for storing in advance reference data corresponding to the cumulative height of normal wrapped coins wrapped in a predetermined number; and detection detected by the detecting means. The data and the reference data stored in the storage unit are compared, and the detection data is set to the upper limit side or the allowable range for the reference data.
In the case of exceeding the lower limit side at least twice consecutively, the excess and deficiency detection control means for correcting the reference data of the storage means based on the detection data is provided, so that the following effects can be obtained. it can. Detection data of the cumulative height of the packaging coins, upper side Oh the allowable range for the reference data
Or, if the value exceeds the lower limit continuously at least twice or more, it is determined that the position of the caulking pawl has shifted due to some cause, such as replacement or adjustment of the caulking pawl, and thereafter, the detection data In order to correct the reference data based on this, it is always possible to accurately determine whether there is no excess or deficiency in the wrapped coins and to process the wrapped coins. As a result, when the disposition position of the caulking claw is deviated from the normal position as in the related art, even though a predetermined number of coins are wrapped, a normal wrapped coin wrapped by the predetermined number is mistaken as an abnormal wrapped coin. The problem of the determination can be solved.

Claims (1)

(57) [Claims] 1. A wrapping film having a width greater than the height of a stack of coins is wound around a predetermined number of stacks of coins so that caulked portions remain above and below the stack of coins, and then moved so as to approach each other. In a coin wrapping machine that forms a wrapped coin by clamping a stack of coins by a pair of enabled staking claws and caulking the swaged portion, the accumulated height of the wrapped coins is determined by the amount of movement of the swaging claw. Detection means for detecting as a reference, storage means for storing in advance reference data corresponding to the cumulative height of normal packaging coins wrapped in a predetermined number of pieces, detection data detected by the detection means and reference data stored in the storage means If the detected data exceeds the allowable range for the reference data at least twice consecutively toward the upper limit or the lower limit at least two times, the reference data in the storage unit is determined based on the detected data.
