Abstract

PURPOSE:To correctly count a number of packed coins without being influenced by difference in thickness of coins. CONSTITUTION:A light projection/reception unit 25 has a light source 23 and a light receiving element 24 opposite at a distance for allowing packed coins 22 to pass through in a plane perpendicular to a center axis line of the coins 22. A moving means 30 allows the packed coins 22 to pass through the light projection/reception unit 25 at a relatively constant speed. A peak detection means 36 obtains all peaks with respect to a change in a light amount received by the light receiving element 24 when the packed coins 22 relatively passes through the unit 25. A unit distance setting means sets the minimum distance between the peaks obtained by the peak detection means or a distance corresponding to one coin per coin type as a unit distance. A number calculating means obtains how many times the unit interval the interval between the respective peaks is to calculate a total of the obtained values. Therefore thickness of each coin is detected in a narrow range with little error.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin counting device for counting the number of coins packed in a coin packaging machine or the like so that it can be confirmed whether or not a predetermined number of coins are packed. .

[0002]

2. Description of the Related Art Conventionally, in a coin wrapping machine or the like, 50 or 25 coins are stacked in the thickness direction, and a wrapping paper is wound around the stacked coins and both ends of the wrapping paper are wound. The coins are wrapped in a roll. Although such packaging coins are extremely rare due to counting errors before stacking coins, or deviations in the timing of stopping the division when sending out the specified number of coins while dividing them into counts, the number of packaged coins is excessive or insufficient. May occur. An excess or deficiency in the number of coins in this package will lead to an unreasonable amount and become a serious problem in financial operations such as banks. Therefore, various devices have been proposed for detecting the excess and deficiency of the number of coins in the packaged coin.

For example, the apparatus disclosed in Japanese Patent Laid-Open No. 63-272644 measures the stacking height of coins and compares whether or not the measured value is within an allowable range with respect to a reference value. If the number of coins is within the allowable range, there is no excess or deficiency in the number of coins, and if it is outside the allowable range, it is determined that there is an excess or deficiency.

Further, this device uses the average value of the height data of the wrapped packaging coins as a reference value of the height data of the packaging coins due to the variation of the thickness of the coins so that the error due to the variation of the thickness of the coins does not occur. The method of correction is adopted.

[0005]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the device described in Japanese Patent No. 2644, excess or deficiency of the number of coins in the packaged coins is determined from the total length of the coins in the stacking height direction, and thus 50 coins having originally different thicknesses are stacked. In this case, there is a problem in that it is impossible to determine the exact excess or deficiency due to considerable variation in the total length. Therefore, in the device, in order to solve this problem, by gradually correcting the reference value by the average value of the height data of the wrapped packaging coins, it is possible to cope with the tendency of variation in the thickness of the coins. However, the corrected reference value is only the tendency of the packed coins that have already been packed and does not indicate the variation in the thickness of the currently packed coins. There is a possibility that an error may occur in the number of packages instead of showing variations.

Further, in the above apparatus, when the number of coins to be packaged is small, for example, when the number of coins to be packaged is about one, the reference value cannot be corrected by the average value, and the package of about 2 to 3 coins is also packaged. There is a problem that the tendency due to variations in the length of coins cannot be fully grasped.

Further, the above-mentioned device has a problem that it can only detect whether the number of packaged coins is large or small with respect to a predetermined number of coins, and cannot count the number of packaged coins such as the number of packaged coins.

The present invention has been made in view of the above problems, and provides a coin counting device for packaging coins, which is capable of accurately counting the number of coins of packaging coins without being affected by the variation in the thickness of coins. To do.

In the coin coin counting device of the present invention, the light source of the light emitting / receiving unit is operated when the packaging coin passes between the light source of the light emitting / receiving unit and the light receiving element at a relatively constant speed by the moving means. The light emitted is transmitted through the small gaps between the coins of the packaging coin, and the transmitted light is received by the light receiving element,
The amount of light received by the light receiving element changes for each gap existing between coins.

Then, the peak detecting means obtains all the peaks with respect to the change in the amount of light received by the light receiving element.

On the other hand, the unit interval setting means sets the minimum interval of the peaks obtained by the peak detecting means or an interval corresponding to one coin of a predetermined denomination as the unit interval, and the number calculating means is the peak detecting means. The number of coins can be obtained by obtaining the multiple of the unit interval set by the unit interval setting means and calculating the total value of the obtained values.
