DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin stacking device for feeding stacked coins to a coin wrapping machine or the like,
The present invention relates to a coin accumulating device capable of effectively detecting occurrence of jam of coins fed from a coin passage when coins are accumulated.

[0002]

2. Description of the Related Art Conventionally, as a coin stacker for detecting a jam of a coin of this kind, a "coin stacker in a coin wrapping machine" disclosed in Japanese Patent Publication No. 5-12213 is known. The coin stacking device disclosed in this publication is an end portion of a coin passage in which coins are horizontally conveyed one by one, and an upper portion of a stacking portion in which coins conveyed by the coin passages are vertically stacked one by one. The coin holding member is fixed at the position, and the coin holding member prevents the coin conveyed through the coin passage from going straight and jumping out.

The stacking section of the coin stacker stacks coins between a pair of stacking drums, and each time coins are fed between the stacking drums, the position of a shelf supporting the stacking coins is increased. In this case, the coin holding member contacts the coin to determine whether or not there is a coin that does not descend from the upper end of the accumulation unit even if the accumulation drum is driven. In addition, if the conduction of the coin is detected by the coin holding member, it is determined that the coin is in a jam state, and the pulse motor is driven to thereby detect the conduction of the coin. Is lowered more than usual.

However, since the above-described coin holding member is provided at the end of the coin passage, the coins that have moved straight through the coin passage are normally accumulated in the accumulation portion in contact with the coin holding member. This is a normal stacking operation, and it is determined that the jam has occurred even though it is not a jam, and the shelves are lowered by more than the set amount. As a result, the upper end of the stacked coins and the coins When a coin is unreeled from the coin passage to the stacking portion in this state, the coin is stood on the top of the stacking coin, and this is the jam. There was a problem that caused the occurrence.

On the other hand, as a technique in which a member (operating member) corresponding to the above-described coin holding member is made movable vertically, a coin accumulating device disclosed in Japanese Patent Application Laid-Open No. Sho 59-51020 is known. This coin accumulating device is configured to push up an operating member when coins conveyed through a coin passage and accumulated in an accumulating portion are higher than a predetermined position. By detecting the upward movement of the member, it is detected that a jam has occurred in the stacking unit, and based on this jam detection, the shelf of the stacking unit is lowered by a predetermined amount.

[0006]

However, in the latter coin accumulating device disclosed in Japanese Patent Application Laid-Open No. Sho 59-51020, when a jam actually occurs and the operating member is lifted, the shelves of the accumulating portion are raised. In this way, an erroneous operation in which the shelf of the stacking unit is lowered despite the absence of a jam as described in Japanese Patent Publication No. Hei 5-12213 is avoided. You can,
On the other hand, at the time of normal accumulation processing,
There is a case that the coin moving up the operating path may be lifted upward by a coin traveling straight on the moving path. There was a risk of causing jamming.

The present invention has been made in view of the above circumstances, and prevents coins from jumping out by a coin holding member during normal stacking, and also prevents jamming of the coins. It is an object of the present invention to provide a coin stacking device that can reliably detect a jam when a jam occurs in the stacking section and immediately lower the stacking section of the stacking section.

[0008]

In order to achieve the above object, according to the present invention, there is provided a conveyor belt stretched from a coin passage to a stacking portion by a pair of pulleys, and the conveyor belt is provided with coins on the coin passage. When the coins are conveyed in the direction of the leading end of the coin path, and the coins are normally accumulated, a driving signal corresponding to the thickness of one coin is output every time the coin counting unit counts the conveyed coins. Is driven, the support position of the stacked coins is lowered in the vertical direction, the coins fed to the stacking unit are stacked one by one, and when a jam occurs in the upper portion of the stacking unit, a jam clearing signal is output, and the stacked coins are output. In a coin stacking device having a control unit for lowering a support position more than normal, a coin holding member provided at an end of a coin passage and at an upper position of the stacking unit to prevent the coin from jumping out of the stacking unit When As well as a rotatable about one end, and a support arm for supporting the pulley of the integrated portion to the other end, are pushed up before <br/> Symbol support arm by the coin jam occurs in the stacking unit upper And a jam detection unit that outputs a jam detection signal by contacting the support arm, and when the control unit receives the jam detection signal of the jam detection unit, outputs a jam clearing signal to the integrated motor. The integrated motor is driven.

[0009]

According to the present invention, coins can be prevented from jumping out and coins can be prevented from being jammed during normal stacking by the coin holding member. Further, when a jam occurs in the stacking unit, the pulley side of the support arm is pushed up by a coin , which is detected by the jam detection unit, and further, when the control unit receives a jam detection signal of the jam detection unit, the stacking motor causes the jam to occur. A jam clearing signal is output to lower the stacking unit shelf, thereby clearing the jam. That is, according to the coin accumulating device of the present invention, during normal accumulation, coins are prevented from jumping out by the coin holding member, and the jam of the coins is prevented beforehand, and when a jam occurs in the accumulating portion. According to the first aspect, the jam detecting section can accurately and reliably detect the jam, and can immediately lower the shelf of the accumulation section.

The number is set in terms of the number of pulse signals supplied to the integrated motor 35 (for example, the number of pulses per coin is 5). Here, the descending amount data will be described with a specific example. Various numbers of pulses indicating the descending amount data are set based on the relationship between the number of coins stacked and the supporting position of the shelves 10. For example, in a case where 100-yen coins are accumulated, it is assumed that the inclination of the thirteenth coin is almost equal to the inclination of the shelves 10 and 10 and the descending amount data corresponding to the coin having the inclination is output. 13
As the coins thereafter increase, the inclination of the coins becomes gentler each time the number of stacked coins is increased, and the descending amount data corresponding to each inclination is output. That is, a predetermined number (for example, 13
