Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a medal feeding device in a medal dispensing machine that dispenses a large number of medals and coins one by one in order to count them.

<Prior art> As a medal feeding device for a conventionally used medal dispensing machine, for example,
2. Description of the Related Art A coin feeding device as disclosed in the above publication is known. That is, in this coin feeding device, a rubber-like supply tube (control tube) made of a separate rubber material is attached to the bottom of a hopper fixed to the machine frame, and a rotary plate is installed below the supply tube with a certain gap between them. , a work ring (regulating plate) which is pressed by a spring is separately arranged on the outer periphery of the lower edge of the supply cylinder, and this works to push the supply cylinder apart and prevent the work ring from floating. Together, these are the basis for sorting medals (coins) into single pieces and sending them out.

<Problems to be solved by the invention> However, this combination of the hopper, the lower supply cylinder, and the work ring has a complicated structure and is of course expensive; The movement is unreasonable, and the jam (biting phenomenon) still cannot be eradicated.

In view of the above circumstances, the present invention aims to provide a medal feeding device for a medal dispensing machine that solves the above problems by making the hopper itself movable without disposing a means for regulating the outer peripheral position of the feeding tube. It is something.

<Means for Solving the Problems> The present invention places a rotating plate directly below a hopper with a lapper-like supply cylinder at its lower end, and uses the centrifugal force of the rotating plate to guide medals to the periphery one by one. In the medal feeding device that feeds out the medals in the direction, the upper periphery of the funnel-shaped hopper body is supported by a plurality of support columns, and the support shaft passing through the upper periphery is
A buffer spring is installed to suppress the upper surface of the upper peripheral edge, and the trumpet-shaped supply tube is integrally formed with the hopper body.

<Function> Due to the above configuration, the medal group put into the hopper is sequentially broken down by the centrifugal force caused by the high speed rotation of the rotary plate installed at the lower end, and moved toward the outer circumference, and then the medals are fed into the hopper-shaped supply cylinder at the bottom. It feeds out one sheet at a time through the gap at the lower end of the sheet. In this case, if two or more sheets enter the gap and a large load is applied to the supply cylinder, the supply cylinder and the hopper body are integrally structured, so the entire hopper body will be forced to press the upper restraining spring. It moves upward against the pressure, lifts the lower edge of the interlocking supply cylinder, and eliminates the jam.

<Example> Hereinafter, the present invention will be explained based on the drawings of the example.

Reference numeral 1 denotes a funnel-shaped hopper body made of hard rubber or the like, and a trap-shaped supply tube 2 that opens in reverse is integrally and continuously formed at the bottom of the hopper body 1. 3
is an upper peripheral edge portion that becomes a flange formed at the upper end of the hopper body 1, and is supported at appropriate locations (four locations in the illustration) on the upper peripheral edge portion 3 by the top portion 5a of a support column 5 installed in the fuselage body 4. At the same time, a support shaft 6 protruding from the center of the top 5a of the support column 5 is attached to the upper peripheral edge 3.
A restraining spring 8 whose upper end that presses the upper surface 3a of the upper peripheral edge portion 3 is locked is attached to the supporting shaft portion 6 which penetrates through the receiving hole 7 and which protrudes from the upper peripheral portion 3. Reference numeral 9 denotes a rotary plate installed below the supply cylinder section 2 at the lower part of the hopper main body 1 with a certain gap a therebetween. 10 is a rotating shaft, and 11 is a cylindrical peripheral wall that becomes a separation ring.

To explain this effect now, first, if an appropriate amount of medals A is put into the hopper body 1, the medals A
The group is appropriately packed so that it bulges on the rotary plate 9 at the lower end.

Here, if the rotary plate 9 serving as the bottom is rotated at high speed, the medal group A on the rotary plate 9 will be sequentially broken down by centrifugal force and will move from the periphery to the outer periphery of the rotary plate 9, and The gap a is regulated by the lower edge of
One sheet enters the inside and is appropriately sent along the peripheral wall 11 to a feeding port (not shown).

In this case, the medals A entering the gap a of the supply cylinder 2 may be
A so-called jam may occur in which two or three sheets overlap in a wedge shape and enter at once. However, the supply tube 2 has a rigid structure that is integrated with the hopper body 1, and the support point of the hopper body 1 is Since the upper peripheral edge 3 of the hopper main body 1 is simply placed on the support column 5, the incoming pressure (load) at this time acts as an upward force, and the upper peripheral edge 3 of the hopper body 1 is attached to the upper restraining spring 8. The supply cylinder 2 is also moved along with this, and the stacked medals A are broken by this partial movement. That is, the supply tube 2 serves as a kind of work ring that tilts as a whole, thereby preventing the medal A from jamming.

<Effects of the Invention> As described above, the medal feeding device in the medal dispensing machine of the present invention has a hopper main body and a flap-like supply cylinder integrally configured, and the upper peripheral edge of the hopper main body is placed on a support column, and the upper peripheral portion of the hopper main body is Since the medals are held down by a spring, the medals on the rotary plate are fed out one by one due to centrifugal force. In this case, even if a jam occurs, the hopper main body is lifted against the spring and the supply cylinder is also moved, thereby reliably eliminating the jam. Moreover, since the present invention has a simple structure consisting of only an integrated hopper body and a supply cylinder, it does not require a dedicated work ring like conventional products, and can be provided at low cost. Of course, since the structure is simple, it has a practical effect that does not cause malfunctions or failures during use.
