DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excess / deficiency detection mechanism for wrapped coins, which can reliably detect whether or not a predetermined number (50) of coins is accumulated.

[0002]

2. Description of the Related Art Conventionally, as a mechanism for detecting excess or deficiency of a wrapped coin of this type, one disclosed in Japanese Patent Laid-Open No. 3-612 is known. The device disclosed in this publication is a coin wrapping machine for sorting only coins of a designated denomination and vertically stacking them, then transferring the stacked coins to a packaging unit and wrapping the stacked coins in a rod shape with wrapping paper. And an excess / deficiency detection mechanism for detecting whether or not the number of accumulated coins accumulated by the coin packaging machine is excessive or insufficient, and the excess / deficiency detection mechanism is provided so as to be movable in the vertical direction. , The upper and lower crimping claws for crimping the upper and lower ends of the wrapping paper wound around the stacking coins, the rotary encoder for detecting the vertical movement amount of the vertical crimping claws, and the stacking based on the output of the rotary encoder And a detection unit that indirectly detects the height dimension of the coin and compares the detected height dimension with preset reference data to determine whether or not the number of accumulated coins is a predetermined number. Has been done.

[0003]

By the way, in the excess / deficiency detection mechanism configured as described above, the stacking height of coins is indirectly detected based on the moving amount of the upper and lower crimping claws, and therefore the coin itself. However, there is a problem that the number of coins cannot be accurately measured. That is, coins such as new coins have burrs, and circulating coins are worn. Therefore, the height dimension of the coins measured by the detecting means fluctuates depending on the ratio of the new coins and the circulation coins mixed in the coins. Therefore, the above-mentioned excess / deficiency detection mechanism updates the reference data itself, which is compared with the measured height dimension of the accumulated coins, to the latest average data to constantly respond to fluctuations in the height dimension of the accumulated coins. I had to. Further, the excess / deficiency detection mechanism configured as described above indirectly detects the height dimension of the integrated coins by the upper and lower crimping claws and the rotary encoder, and further includes dimensional errors such as burrs and abrasion. , The accuracy is low because it determines whether or not a predetermined number of coins have been accumulated.
There is a problem in that it is erroneously determined that there is a predetermined number of coins, even though there are not a predetermined number of accumulated coins.

The present invention has been made in view of the above circumstances, and detects the number of accumulated coins by counting the boundary lines of the coins, whereby the influence of burrs, abrasion, etc. is detected. It is an object of the present invention to provide a mechanism for detecting excess or deficiency of packaged coins that can perform excluded detection.

[0005]

In order to achieve the above object, in the first aspect of the present invention, an excess or deficiency detection of packaging coins is performed to detect whether or not there are a predetermined number of coins in the packaging coins wrapped by the transparent packaging paper. A mechanism for irradiating the packaging coin with light in the longitudinal direction, and detecting the light amount of the reflected light reflected from the packaging coin along the length direction of the packaging coin, and the light amount of the reflected light. Based on the detection signal from the reflected light detection sensor and the reflected light detection sensor, the boundary line of the coin in the packaging coin is detected and counted, and the count value of this boundary line is output as detection data. A boundary line counting section,
The detection data output from the boundary line counting unit is compared with reference data stored in advance, and based on the comparison result,
A comparison unit for detecting excess or deficiency of coins in the packaged coins is provided.

In the second invention, the boundary line counting section is made to detect the boundary line of the coin from the waveform data obtained by integrating the detection signal from the reflected light detection sensor.

[0007]

In these inventions, the boundary line counting unit counts the boundary lines of the coins in the packaged coins based on the detection signal from the reflected light detection sensor, thereby substantially counting the number of accumulated coins. This makes it possible for the comparison unit to accurately determine whether or not the number of coins in the wrapped coins is excessive or insufficient. That is, the height dimension of the packaging coins is indirectly detected, and in comparison with a conventional excess / deficiency detection mechanism that detects excess or deficiency of accumulated coins by further including dimensional errors such as coin burr and wear. It becomes possible to accurately detect the excess or deficiency of coins.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a schematic configuration diagram of a coin wrapping machine. In this drawing, reference numeral 1 denotes three wrapping rollers provided rotatably about a vertical axis. These wrapping rollers 1 each have a coin accumulation and packaging portion 2 formed at the center thereof.
Coins are fed inside one by one and accumulated vertically. The accumulated coins 4 accumulated in the coin accumulating and packaging unit 2 are held by the three wrapping rollers 1 in a sandwiched state, and the wrapping rollers 1 and the accumulating coins 4 circle while rotating the wrapping rollers 1. By sandwiching the transparent wrapping paper 3 between itself and the peripheral surface, the transparent wrapping paper 3 is wound around the coins 4. The wrapping roller 1 is located at a position slightly separated from the accumulated coins 4 while coins are accumulated in the coin accumulating and wrapping unit 2, but when the transparent wrapping paper 3 is wound, they are close to each other. The accumulated coins 4 are held between the packaging rollers 1.

On the other hand, in the vicinity of the packaging roller 1,
Upper and lower caulking claws (not shown) for caulking the upper and lower ends of the transparent wrapping paper 3 wound around the coins 4 are provided. The upper and lower crimping claws are provided so as to be close to and away from the accumulated coins 4 accumulated in the coin accumulating and packaging unit 2, and the transparent wrapping paper 3 wound around the accumulating coins 4 at the time of approaching. The upper and lower ends of the transparent wrapping paper 3 are crimped by pressing and pressing the stacking coin 1 to rotate the coins 4 in this state. In addition, in FIG. 2, a rounded portion (a portion indicated by a solid line) near the upper and lower ends of the accumulated coins 4 is a crimped portion 3A of the transparent wrapping paper 3, and a portion extending vertically from the crimped portion 3A (two The part indicated by the dotted line) is the end 3B before the transparent wrapping paper 3 is crimped.
It is. Therefore, the end portion 3B of the transparent wrapping paper 3 wrapped around the circumferential surface of the accumulated coin 4 is configured such that all the portions indicated by the chain double-dashed line are rolled inward by the crimping claws. In the following description, the accumulated coin 4 around which the transparent wrapping paper 3 is wrapped will be referred to as a “wrapping coin M”.

Next, an excess / shortage detecting mechanism for detecting whether or not the number of coins in the wrapped coin M is sufficient or not will be described with reference to FIGS. First, reference numeral 5 shown in these figures denotes a lamp arranged on the front side (the front side of the apparatus) of the coin stacking and packaging portion 2 into which the upper and lower caulking claws enter.
As shown in, the coin stacking unit 2 is provided in the vertical direction. Reference numeral 6 is a CCD that detects reflected light when the packaging coin M is illuminated by the lamp 5 and outputs a detection signal corresponding to the brightness of the reflected light. As shown in FIG. The transparent wrapping paper 3 is provided in the vertical direction along the coin collecting and wrapping portion 2 and is set to have a wider range than the width of the transparent wrapping paper 3 before crimping (width before crimping).

FIG. 3 shows a predetermined number of coins 4 accumulated in the coin accumulation and packaging unit 2 (50 coins in this embodiment).
A control unit for detecting whether or not there is a signal, comprising: an amplifier 7; a boundary line counting unit 8; a reference value storage unit 9;
0. The amplifier 7 amplifies the detection signal output from the CCD 6 and supplies the amplified detection signal to the boundary line counting section 8.

The boundary counting unit 8 integrates the detection signal of the CCD 6 amplified by the amplifier 7, and based on the waveform data (shown by (a) and (b) in FIG. 4), the packaging coin M The counted value is supplied to the comparing unit 10 as detection data. The transparent wrapping paper 3 wrapped around the stacking coin 4 is printed with the denomination, the amount of money, the name of the financial institution, etc. Therefore, when the packaging coin M is detected, it is affected by these printed characters. However, since the CCD 6 directly detects the wrapping coin M rotated by the wrapping roller 1, the detection signals of the CCD 6 are averaged and are not affected by these printed characters.

The reference value storage section 9 stores reference data to be compared with the detection data supplied from the boundary line counting section 8. That is, when the packaging processing is normally performed, the number of the coins of the packaged coin M is 50, so that the boundary line becomes 51 (including the upper and lower ends in the boundary line), whereby the reference value storage unit 9 stores In the table, the number of boundary lines (51 lines) assuming that the packaging process has been performed normally is stored as reference data.

The comparison unit 10 compares the detection data from the boundary line counting unit 8 with the reference data from the reference value storage unit 9,
If they match, a normal signal is output, and if they do not match, an abnormal signal is output. That is, in the comparison unit 10,
It is determined whether or not the detection data supplied from the boundary line counting unit 8 matches the reference data indicating the 51 lines supplied from the reference value storage unit 9, and the determination is made by the boundary line counting unit 8 based on this determination. When the detected detection data indicates 51, a normal signal is determined to be normal, and when the detection data is a value other than 51, an abnormal signal is determined to be abnormal.
Then, the normal signal and the abnormal signal output from the comparison unit 10 are supplied to an output unit (not shown), and the output unit informs the worker that an abnormality has occurred during the packaging of coins based on the abnormal signal. I am trying to do it.

Next, the processing contents of the detection signal in the boundary line counting section 8 will be described with reference to FIG. The boundary line counting unit 8 integrates the detection signal of the CCD 6 amplified by the amplifier 7, and as a result, obtains waveform data shown in FIGS. The waveform data of reference numeral (a) is before the transparent wrapping paper 3 is crimped by the upper and lower crimping claws, and the waveform data of reference numeral (b) is that the transparent wrapping paper 3 is crimped by the upper and lower crimping claws. It is the latter one. Then, in the waveform data (a) before crimping the transparent wrapping paper 3, the reflected light is reflected from the end portion of the transparent wrapping paper 3 (the portion indicated by the chain double-dashed line 3B in FIG. 2) as indicated by the reference numeral (c). Therefore, both ends of the waveform are H, while in the waveform data (b) after the transparent wrapping paper 3 is crimped, the ends of the transparent wrapping paper 3 are bent (see FIG. 2). 3A), reflected light from the transparent wrapping paper 3 is not obtained, and therefore, both ends of the waveform are L as shown by the symbol (d).

Although the transparent wrapping paper 3 is formed of a transparent plastic sheet, the transparent wrapping paper 3 is not in close contact with the cylindrical surface of the stacked coins 4, that is,
In the portion 3B indicated by the two-dot chain line in FIG. 2, irregular reflection of light occurs on the surface, and the waveform data (a) becomes H level as shown by (c). On the other hand, when the transparent wrapping paper 3 is in close contact with the cylindrical surface of the coins 4, the light does not reflect on the surface, and the light passes through the transparent wrapping paper 3 as indicated by reference numerals (A) and (B). Then, the light is reflected by the cylindrical surface of the integrated coin 4 which is in close contact with the transparent wrapping paper 3.

Waveform data (a) and (b) in FIG.
The range shown in (B) will be described. These (A)
The range shown in (B) shows the waveform data of the portion where the integrated coins 4 are wrapped by the transparent wrapping paper 3, and the place where “H” is shown in these (A) and (B) is Indicates that the light of the lamp 5 has passed through the transparent wrapping paper 3 and has been reflected by the cylindrical surface of the stacked coins 4. On the other hand, the light "L" indicates that the light of the lamp 5 has passed through the transparent wrapping paper 3. It shows that the coins 4 have been absorbed between the coins (that is, the boundary line). Note that light is also absorbed at the upper and lower ends of the coins located at the upper and lower ends of the stacked coins 4, whereby “L” as indicated by reference numerals (a) and (b) is obtained.
Level. In the boundary line counting section 8, the waveform data (a) and (b) (a) and (b) are also included in the boundary line of coins.

In the boundary line counting section 8, "L" in the range shown by (A) and (B) in the waveform data (a) and (b) is a number representing the boundary between coins of the stacked coins 4. As the detection data.
0, and the comparing section 10 determines whether or not the number of coins 4 is normal based on the detection data.

As described in detail above, in the excess and deficiency detection mechanism for packaged coins according to the present embodiment, the boundary line counting section 8 counts the boundary lines of the coins in the packaged coins M, so that the coins are substantially coined. Can be counted, whereby the comparison unit 10 can accurately determine whether or not the number of coins in the wrapped coins M is excessive or insufficient. That is, as compared with the conventional excess / deficiency detection mechanism which detects the excess / deficiency of the accumulated coins by indirectly detecting the height dimension of the packaging coin M and further including the dimensional error such as burrs and wear of the coins. The effect that the excess / shortage of coins can be accurately detected is obtained.

Incidentally, the waveform data (a) is shown in FIG. 4 of the present embodiment.
As shown in (b), the pulsed “L” signal is obtained before the transparent wrapping paper 3 is crimped by the upper and lower crimping claws and after the transparent wrapping paper 3 is crimped by the upper and lower crimping claws. Since it is effectively detected, the timing of detecting the reflected light by the CCD 6 and the timing of counting the boundary line by the boundary line counting unit 8 are determined before and after the transparent wrapping paper 3 is crimped.
It may be set to any value after crimping. Further, in the present embodiment, the number of coins accumulated is set to 50,
The number of sheets can be arbitrarily set by changing the setting of the reference data in the reference value storage unit 9.
Furthermore, in this embodiment, the excess / deficiency detection mechanism of the packaging coin M is
The case where the coin is packed in the coin wrapping machine between the wrapping rollers 1 has been described, but the present invention is not limited to this. For example, coins stacked by an independent stacking mechanism may be inserted between the wrapping rollers. It may be incorporated into a coin wrapping machine that sends in and winds and wraps the transparent wrapping paper.

As is apparent from the above description, in these inventions, the boundary line counting unit counts the boundary line of coins in the packaging coin based on the detection signal from the reflected light detection sensor. It is possible to substantially count the number of coins accumulated, thereby enabling the comparing unit to accurately determine whether the number of coins in the wrapped coins is excessive or insufficient.
That is, the height dimension of the packaging coins is indirectly detected, and in comparison with a conventional excess / deficiency detection mechanism that detects excess or deficiency of accumulated coins by further including dimensional errors such as coin burr and wear. The effect that the excess / shortage of coins can be accurately detected is obtained.
