[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin wrapping machine in which a wrapping paper is wound around a circumference of a coin by rotating while holding a stack of coins with three wrapping rollers. The present invention relates to a stacked coin shortage detection device in a coin wrapping machine that detects whether a predetermined number of stacked coins are stacked.

[0002]

2. Description of the Related Art Conventionally, a coin wrapping machine capable of detecting whether or not a predetermined number of coins to be wrapped are stacked has been disclosed in, for example, Japanese Utility Model Publication No. 58-56165. Has been adopted. In this coin wrapping machine, a predetermined number of coins, for example, 50 or 25 stacked coins are stacked in the coin stacking section, and the lower surface of the stacked coins is supported by a vertically movable support rod, and the coin is stacked in a packing section having three packing rollers. After moving down, at least one of the three wrapping rollers is moved inward, and then the three wrapping rollers are used to hold the stacked coins and rotate the stacked coins by rotating the wrapping rollers. While wrapping, the wrapping paper is wound around the circumference of the stacked coins, and the both ends of the wrapping paper are wound by the winding hook to perform the wrapping.

In the conventional coin wrapping machine, coins have different thicknesses depending on denominations, the height of stacked coins changes for each denomination, and coins having different heights are wrapped with common wrapping paper. Therefore, when the stacked coin is lowered from the coin stacker to the wrapping unit by the support rod and positioned between the wrapping rollers, the center in the height direction of the stacked coin is substantially coincident with the center in the width direction of the wrapping paper. A structure like that was adopted.

On the other hand, for example, as described in Japanese Utility Model Laid-Open No. 64-35808, it is determined whether or not a predetermined number of stacked coins are stacked, that is, whether the number of wrapped coins is too small or too small. There is known an apparatus for detecting whether or not an error has occurred. This device detects the relative amount of movement of the upper and lower winding hooks when winding both ends of the wrapping paper wound around the coins as the rotation amount of the rotary encoder by the interlocking mechanism of the rack and the pinion. However, a structure is employed in which whether the number of stacked coins is too small or too large is detected depending on whether the rotation amount is larger or smaller than the rotation amount obtained when a predetermined number of coins are stacked.

[0005]

[Problem to be solved by the present invention]
In the device described in Japanese Patent Application Publication No. 808, which detects the excess or deficiency of the number of stacked coins, the relative amount of vertical movement of the upper and lower hooks of the coin wrapper is converted into the amount of rotation. In addition, an interlocking mechanism with a rack and pinion is provided,
A rotary encoder for detecting the amount of rotation is required, and expensive parts must be used.

Further, the conventional apparatus is capable of detecting excess or deficiency of stacked coins, that is, whether the number of coins is larger or smaller than a predetermined number. It is an abnormality that coins fall while moving the coins from the wrapping part to the packaging part, in most cases that the coins are insufficient than a predetermined number, and it is also possible to detect when the coins are more than a predetermined number Has little meaning, and only causes high costs.

Further, in the above-described conventional apparatus, the timing at which the number of coins can be detected is either the time when the winding hook completes the winding, that is, the time when the packaging is completed. There is a problem in that the wrapping paper is created and wasted, and the wrapping paper must be broken. Also, if you leave the wrapping paper of the abnormal number of wrapped coins unbroken,
There was a risk that the coin was incorrectly used as a normal wrapped coin.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a shortage detecting device for a coin wrapping machine capable of detecting shortage of a stacked coin with a simple configuration before starting packaging. Things.
