Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin wrapping machine which winds and wraps a predetermined number of strips of wrapping paper around a predetermined number of coins.

[0002]

2. Description of the Related Art Conventionally, a coin wrapping machine described in, for example, Japanese Patent Publication No. 1-34846 is known. This type of coin wrapping machine accumulates a predetermined number of coins (generally 50 coins), holds them between three rollers called wrapping rollers, and rotates the rollers to form a strip of wrapping paper around the coins. Coins are wrapped by winding the upper and lower ends of the wrapped wrapping paper with a winding needle.

The supply of the wrapping paper is performed by feeding the strip-shaped wrapping paper drawn from the wrapping paper roll by the supply roller to the wrapping portion along the non-linear wrapping paper guide passage, and the tip of the wrapping paper fed to the wrapping portion. Is sandwiched between the three rollers that are rotated and the coins that are nipped and rotated by these rollers, so that a sudden tension is applied to the wrapping paper, and the wrapping paper is placed on the orbit of the wrapping paper in the tensioned state. The cutter is pressed against a cutter protruding in a V shape in the feeding direction and cut, and the cut wrapping paper piece is wound around the peripheral surface of the accumulated coins.

In addition, when a new wrapping paper roll is set or when a wrapping paper roll whose leading end does not have a V-shaped projection in the feeding direction due to cutting with scissors or the like is used, The tip of the paper is sent to the wrapping paper guide passage, and the wrapping paper is pressed against the cutter and cut by pulling the tip of the wrapping paper by an operator's manual operation to make it tense, and the tip protrudes in a V shape in the feeding direction. The unwrapped wrapping paper piece is removed, and the tip of the remaining wrapping paper is projected in a V-shape in the feeding direction.

The reason why the leading end of the wrapping paper is formed in a V-shape is that when the wrapping paper is not V-shaped, one end in the width direction of the wrapping paper is gripped first and is slanted. This is because a feeding failure or winding failure such as feeding or winding the coin diagonally occurs.

[0006]

In the conventional coin wrapping machine, an operator manually pulls the tip of the wrapping paper and cuts it with a cutter in order to make the tip of the wrapping paper project in a V-shape. Therefore, there is a problem that it takes time and effort to set the wrapping paper.

Therefore, the present invention has been made in view of the above point, and automatically cuts the leading end portion of the wrapping paper and eliminates the cut wrapping paper piece only by a simple operation of setting the wrapping paper. Then, an object of the present invention is to provide a coin wrapping machine that can make the tip of the remaining wrapping paper into a predetermined shape.

[0008]

According to the present invention, there is provided a first wrapping paper feeding means 26 for feeding and feeding a band-shaped wrapping paper, and a second wrapping paper provided at a predetermined distance from the first wrapping paper feeding means 26. Of the wrapping paper feeding means 51, the guiding means 39 for guiding the wrapping paper P non-linearly between the first and second wrapping paper feeding means 26, 51, and the first and second wrapping paper feeding means 26. , 51 and a cutter 43 that cuts the wrapping paper P by coming into contact with the wrapping paper P when the wrapping paper P is pulled and linearly displaced due to the difference in the feeding speed of the coins 51. In a coin wrapping machine that winds and wraps a band-shaped wrapping paper P having a predetermined length on a winding position for guiding the wrapping paper P delivered from the second wrapping paper feeding means 51 to the periphery of the coin. A paper guide member 61 provided so as to be movable between two positions, that is, an exclusion position for guiding to the exclusion unit 71; When the paper guide member driving means RSD for driving the paper guide member 61, the switch means SW1 for outputting a cutting command signal, and the leading end of the wrapping paper P supplied to the first wrapping paper feeding means 26 are set. In response to a signal from the switch means SW1, the paper guide member driving means RSD is operated to move the paper guide member 61 to the exclusion position, and the first and second wrapping paper feeding means 26, 51 are operated. And a control unit 91 for controlling to cut the wrapping paper P and remove the cut leading end.

[0009]

In the present invention, when the front end of the wrapping paper P is set to the first wrapping paper feeding means 26, when the wrapping paper P is set, a signal from the switch means SW1 causes the paper guide member driving means RSD to guide the paper. The member 61 is moved to the exclusion position, and the first and second wrapping paper feeding means 26, 51 are activated. Due to the difference in feed speed between the first and second wrapping paper feeding means 26, 51, when the wrapping paper P is pulled and linearly displaced, it contacts the cutter 43 and is cut. The cut wrapping paper piece of the wrapping paper P is excluded by the paper guide member 61.
Eliminated to 71.
