Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a metal supply device for a metal rental machine that sells metal used in game equipment at game centers and the like.

<Prior art> Conventionally, the metal feeding device of this type of metal rental machine that is commonly used has a hopper at the top of the vertical casing (body), and the metal flowing out from the bottom end of the funnel is distributed downward. The structure is such that the metal is supplied to the metal feeding device. For this reason, as a metal feeding means in normal use, for example, metal packed in bags must be lifted up to the top of the machine body one by one to be filled, resulting in a heavy load and poor workability. Moreover, since this aircraft is usually a rectangular vertical type, placing heavy objects at the top lacks physical stability, which could lead to unexpected accidents in the event of an earthquake or other disaster. .

<Problems to be solved by the invention> In view of the above-mentioned circumstances, the present invention aims to provide a metal feeding device for a metal rental machine that facilitates metal loading and provides a stable aircraft. .

<Means for solving the problem> The present invention is a metal rental machine equipped with a hopper type metal supply tank, in which the hopper is installed at the lower end of the metal rental machine body, and one side wall surface formed at the bottom of the hopper is installed at the lower end of the metal rental machine body. A clogging prevention horizontal rod is provided on the sloping bottom surface facing toward the side, and the tip thereof can be freely fed out to an outlet section 8 bored in one side wall, and a baffle plate is attached to the upper part of the hopper, and a receiving tank is connected to the outlet section. The lower end of a bucket-shaped inclined belt conveyor is provided with flight sections protruding at regular intervals, and the chute provided at the back of the top of the inclined belt conveyor faces a centrifugal metal feeding device. It is something.

<Function> Due to the above structure, when supplying metal, simply open the front door of the main body, and the hopper is located at the lower end of the door, so you can open the metal such as a bag. Of course, this hopper is located at the lower end, so
The shape of the hopper itself is also larger than that of the upper end type. In addition, since this metal is moved continuously by a bucket-shaped inclined belt conveyor with a predetermined intermittent drive, there is no need to supply more than necessary to the centrifugal metal feeding device that is the pumping destination. Nor. Furthermore, in this case, since the lower end of the hopper has a horizontal rod to prevent the hopper from clogging, there is no problem with pumping up the inclined belt conveyor, and the technical problem has been solved.

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

Reference numeral 1 denotes a metal lending machine main body in which a currency exchange mechanism 2, a banknote detection mechanism 3, and a control unit 4 are arranged on the upper part, and a metal ejection mechanism 5 is provided in the middle position, which reaches the bottom of the main body 1 which is a vertical casing. A hopper 7 with a replenishment door 6 disposed on the front surface of the upper part is installed at the lower end 1a position. The configuration of this hopper 7 is that it has an inclined bottom surface 7b so that the valley faces toward the one side wall surface 7a, and an outlet portion 8 is bored at the lower end of the one side wall surface 7a in the lower surface of the inclined bottom surface 7b.
a horizontal stabbing rod 9 for preventing clogging, the tip of which is guided by;
A small horizontal thrusting rod 9' branched from the base of the horizontal thrusting rod 9.
, and a plurality of baffle plates 10 protruding from the side wall are arranged above. 11 is the exit part 8 of the hopper 7
It is a bucket-shaped inclined belt conveyor that stands up with its lower end facing a receiving tank part 12 connected to the side of the belt. A belt body 1 has a number of integrally protruding flight parts 15 having the same width and a certain length.
6, and the entire belt body 16 is housed in a housing 17. Reference numeral 18 denotes a chute inclined to one side provided on the top rear surface of the inclined belt conveyor 11, and the metal discharging mechanism 5 includes a guide path 19 end continuous with the chute 18 provided in the middle stage of the main body 1, and is a known centrifugal type metal feeding device. It's like heading towards 20.

To explain this operation now, first, a predetermined amount of metal A is filled into the hopper 7, which serves as a metal supply tank.

Here, the metal dispensing device 20 rotates due to a signal from a banknote or coin slot (not shown) placed on the front of the metal lending machine, and discharges a desired number of metal A from the takeout slot. (Publicly known means). In this state, when the number of metal sheets in the rotating disk tank of the metal feeding device 20 decreases, a predetermined amount detection sensor (not shown) is activated and the inclined belt conveyor 1
1 is driven to rotate the inclined belt conveyor 11 for a certain period of time. When this inclined belt conveyor 11 rotates, metal A group flowing into and clogging the receiving tank 12 at the lower end,
The lifting flight part 15 protruding from the belt main body 16 scrapes up and conveys an appropriate number of sheets, and when in the upper position, the metal A in the lifting flight part 15 falls onto the chute 18 by reversing to the return side. The rotating disk tank of the metal feeding device 20 connected to the chute 18 is filled by the reduced amount. That is, when the sensor of the rotating disk tank detects a predetermined amount, the drive of the motor 21 is stopped in conjunction with this.

On the other hand, if the amount of metal in the receiving tank 12 decreases due to metal pumping up as the inclined belt conveyor 11 rotates, the hopper 7 is The metal A sequentially flows in due to the pressure caused by the funnel inclination, but at this time, the horizontal thrust rods 9 and 9' arranged on the inclined bottom surface 7b of the hopper 7 are interlocked with the crank wheel 23 which is rotated by the drive of the motor 22. It was hit sideways and the receiving tank part 12
Good metal outflow to the side. In this case, the long horizontal thrust rod 9 whose base end is pivotally connected to the crank wheel 23 slides on the support roller 24, and the tip 9a slightly enters the receiving tank section 12 (however, the lifting flight section 15
(to the extent that it does not come into contact with the support roller 24), the small horizontal thrusting rod 9' branched and connected from the middle of the horizontal thrusting rod 9 is connected to the supporting roller 24.
Since it slides on the support roller 25 located higher up, this tip 9a' is pushed up slightly diagonally upward, which prevents arch cavities that are likely to occur with loose materials. In addition, a remaining chute 26 is arranged at a midway position on the return side of the inclined belt conveyor 11,
The chute 26 is configured to return directly to the upper part of the hopper 7. This is because even if the lifting flight part 15, which uses a bucket, moves to the return side, it may become clogged strongly.
The remaining metal A that has not yet fallen off at the top of the return due to pressure contact and sliding with the side wall surface of the housing 17, etc.
It is something that receives. Further, the baffle plate 10 protruding from the vicinity of the valley of the hopper 7 is used to remove unnecessary packing pressure caused when reinforcing metal is introduced or when a large amount of metal is packed.

<Effects of the invention> As mentioned above, the metal feeding device of the metal rental machine of the present invention has a metal hopper at the lower end of the machine body, and a bucket-shaped inclined belt conveyor on the side of the metal hopper, so that the pumped metal can be continuously conveyed. By adopting a structure that allows the metal to be fed to the metal discharge mechanism (centrifugal metal feeding device side), the hopper shape can be made into a large capacity tank (for example, the capacity of the conventional 10,000 metal tank has been reduced to 3. (Can accommodate 1,000,000 pieces), metal replenishment work can be done from a low position in the front, and it is easier to handle without having to lift heavy bags to the top of the machine as in the past. Of course, since the center of gravity of the entire aircraft is lowered and stabilized, it is possible to eliminate the possibility of it toppling over in the event of an earthquake. Furthermore, since this hopper is equipped with a metal horizontal punching rod for punching down, it is possible to smoothly flow out to the inclined belt conveyor side. Furthermore, this conveyor is made of rubber and the orthogonally protruding lifting flight part is integrally formed, so there is no breakage or other failure of the lifting flight part, and there is no unnecessary slippage when scraping metal at the receiving tank position. Reliable pumping is achieved, and the lifting flight section, together with the side wall surface of the housing and the belt surface, forms a kind of bucket structure in the carrier section, and has practical effects such as stable metal transport.
