Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a metal discharging device in a metal lending machine used in a game hall or the like.

<Prior Art> Conventionally, as a commonly used metal (coin) dispensing device, for example, a change device disclosed in Japanese Patent Application Laid-Open No. 47-38098 is known. In this system, a coin case equipped with a rotary disk for discharging single coins directly faces directly below the payout end of a coin delivery section consisting of a belt conveyor placed at the bottom end of a funnel-shaped hopper, and one end of the coin case A ratchet wheel having an arc-shaped portion on the outer periphery is attached to the side of the feed mechanism disposed on the drive mechanism, and a rotation detecting section disposed at one end of the ratchet wheel is linked to the counter mechanism.

<Problems to be solved by the invention> Namely, in this type of metal discharging device, a group of metals (coins) are thrown into the hopper all at once, and therefore small wastes such as paper scraps and metal pieces are not collected. These dusts are thrown in together with metal and adhere to machine parts, often interfering with smooth operation and causing breakdowns. In addition, if the metal that has been put into the hopper is to be taken out due to a malfunction or other than the specified count, it is usually necessary to disassemble a part of the mechanism or scoop out the metal group in the hopper one by one. It was a hassle.

The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a metal discharge device for a metal lending machine in which a slanted introduction plate with a freely switchable supply switch is provided between the hopper and the turntable to facilitate removal of metal from inside the hopper in the event of a breakdown, etc., and the slanted introduction plate itself acts as a garbage sieve so that paper, metal pieces, etc. are not guided to the turntable side.

<Means for solving the problem> The present invention introduces a sloping wire-mesh-like bottom with an outlet at both ends, which is also used to remove contaminants, at a position directly below the feeding end of the belt conveyor placed at the lower end of the metal feeding hopper. The plate 3 is installed so that its inclination direction can be changed freely, and a rotary disk for discharging one sheet is provided at the lower part of one inclined end of the inclined introduction plate, and a machine body is installed at the lower part of the other inclined end of the inclined introduction plate. An external discharge port facing the outside is located, and a metal counting star wheel is attached to the side of a conveying passage connected to one end of the rotary disk, which rotates to meet the outer diameter of the metal.

<Operation> Due to the above-described structure, the metal flowing out from the hopper passes through the belt conveyor, falls onto the inclined introduction plate, slides on this slope, and flows into the rotary plate at the lower end of the slope that is always facing. In this case, since at least a portion of the bottom surface of the inclined introduction plate is mesh-shaped, even if there is dirt mixed in when charging the hopper, it falls through the mesh and only metal falls into the rotary disk. Therefore, failures such as clogging will not occur in the conveyance path through which sheets are discharged one by one from the rotary disk. In addition, when it is desired to remove the metal that has been put into the hopper for reasons of counting or due to mechanical failure, the direction of inclination of the inclination introduction plate interposed between the hopper and the rotary plate can be reversed using appropriate means. If so, the other outlet will be lowered to face the external outlet, so it can be easily taken out of the aircraft.

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

1 is a hopper section that stores metal, and a belt conveyor 2 that rotates intermittently is arranged at the bottom end of the funnel.
Directly below the feeding end of the belt conveyor 2, there is provided a see-saw-like inclined introduction plate 3 which is freely movable and whose both ends are outlet ports, serving as a metal supply means. Place. In this case, the structure of the inclined introduction plate 3 is that the bottom surface 3d has a net-like structure with many holes 21, and two support shafts 3a, 3a are provided on the lower surface of the bottom surface 3d.
are inserted into hooked grooves 3b, 3c, respectively, bored in both side walls of the support frame 22, which surrounds the inclined introduction plate 3 and has a U-shaped cross section. ', 3c' are arranged in symmetrical positions, and one support shaft 3a
is located in the hooked part 3c' of one hooked groove 3c, the other support shaft 3a is located in the flat part of the other hooked groove 3c, the bottom surface 3d is tilted to one side, and the support shaft 3a, The inclination can be changed by moving the position of 3a in the opposite direction to that described above (see Figure 2 A and B).

To explain this operation now, first, the metal fed into the hopper 1 is transferred to the belt conveyor 2 at the lower end.
are sequentially delivered by the drive of the conveyor belt 2, and are dropped onto the inclined introduction plate 3 directly below the end of the belt conveyor 2. This inclined introduction plate 3 is configured such that the support shafts 3a, 3a are always set to the hooked grooves 3b, 3c so as to face the metal counter 4 side (see Fig. 2A and Fig. 4 solid line). , the metal on the inclined introduction plate 3 slides and flows into the rotary plate 4 at the lower end of the slope. This inclined introduction plate 3
When sliding, since there are many holes 21 on the bottom surface 3d, contaminants, dust, etc. are separated from the metal and fall through the holes 21.

Therefore, only metal is supplied to the rotary disk 8 of the metal counter 4, and the centrifugal force of the rotary disk 8 causes the metal to flow along the partition wall 18 on the outer periphery of the conveying path 1.
1 to the starting end 9. A discharge belt 10 suspended linearly from the circumference of the rotary disk 8 toward the metal discharge port pumps the metal along the passage regulating piece 12 and the guide piece 13, and transfers the metal to the star wheel 14 on the side of the terminal end. Pander to metal. The star wheel 14 rotates in synchrony with the ejection metal, causing rotating vanes (not shown) to rotate. A sensor (not shown) performs counting based on this rotational speed, and the metal that has left the star wheel 14 falls from the discharge section 15 through the discharge port 5 shown in FIG.

Furthermore, if the slope of the inclined introduction plate 3 is switched to the external discharge port 6 side, the metal in the hopper 1 is carried to the belt conveyor 2 and discharged to the external discharge port 6 via the inclined introduction plate 3 (see Fig. 4). In other words, if there is a failure on the metal counter 4 side, or if you want to stop metal counting midway and remove the remaining metal, use the appropriate switching interlocking means (see double-dashed line) installed outside or inside the machine. (not shown) or by grasping and moving the inclined introduction plate 3 itself to move the set position of the support shafts 3a, 3a of the inclined introduction plate 3 relative to the hooked grooves 3b, 3c (see Fig. 2). Like a hook or groove 3
(The support shaft 3a in the hooked part 3b' slides the support shaft 3a in the hooked groove 3c to the flat part at the upper end, and the inclination changes), and the inclination of the inclined introduction plate 3 is changed from the outside. If the belt conveyor 2 is then driven toward the discharge port 6 side, all of the metal in the hopper 1 will be discharged down to the external discharge port 6.

In addition, the belt conveyor 2 disposed directly below the hopper 1 is operated by a limit switch 16 for level detection fixed to the partition wall 18 of the rotary disk 8.
When a certain amount of metal is supplied into the rotary disk 8, the switch is shut off, the belt conveyor 2 is stopped, and the belt conveyor 2 is operated intermittently so that the appropriate amount of metal always remains on the rotary disk 8. Adjust the remaining amount of metal.

<Effects of the invention> As mentioned above, the metal discharging device of the metal rental machine of the present invention has the hopper and counting machine of the metal supply section arranged separately, and the hopper and counting machine of the metal supply section are arranged directly below the intermittent rotating belt conveyor in the middle. By interposing an inclined introduction plate whose inclination can be freely switched between the counter side and the external discharge port side, metal can be easily taken out to the outside as necessary. In other words, when you want to cut off the supply of metal to the rotary disk and take it out of the machine due to machine failure or for counting purposes, the metal that has been fed into the hopper can be taken out of the machine by using a single inclined introduction plate interposed between the hopper and the rotary disk. By simply switching the inclination of the two to the opposite direction and making the other outlet face the external outlet, the outlet can be automatically discharged and taken out, and since a single inclined introduction plate is used, it can be installed compactly. Of course, in this case, the inclined introduction plate has a net structure with holes etc. that should allow debris to fall.
Contaminants and dirt that are mixed with the metal when being fed into the hopper are dropped and removed, the occurrence of failures such as clogging caused by the dirt is minimized, and the metal is clean and hygienic. In addition, the amount of metal supplied to the counting machine is appropriate, and it has practical effects such as being able to supply metal at high speed in proportion to the circumferential speed of the discharging belt of the counting machine.
