Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a coin hopper used for supplying coins for change in a vending machine, a ticket vending machine, a ball rental machine in a pachinko game, and the like.

(Prior Art) In a conventional coin hopper of this type, a disc having a hole for accommodating coins is rotatably supported on a bottom surface of a hopper body by a motor or the like so that one coin is ejected to one coin. Is configured.

The accommodation holes formed in the disk are formed at equal intervals on the circumference.

(Problems to be Solved by the Invention) In the above-mentioned conventional coin hopper, the accommodating holes formed in the disk mounted in the hopper main body are provided at equal intervals on the circumference. Coins are continuously discharged at regular intervals.

Therefore, when the coins discharged from the coin hopper are transported to another place by a coin transport elevator or the like, it is very difficult for the coin transport elevator or the like to receive the coins discharged at regular intervals with good timing, Once the timing is out of order, the conveyance becomes impossible, and there is a problem that the operation must be stopped once and the tent adjustment must be performed.

The present invention has been made in view of the problems of the conventional technology as described above, and its purpose is to smoothly transfer coins discharged from a coin hopper to other transporting means, and An object of the present invention is to provide a coin hopper that can easily perform timing adjustment.

Another object of the present invention is to provide a coin hopper in which the supply of coins to the coin hopper is automatically performed efficiently by detecting the remaining amount.

(Means for Solving the Problems) In order to achieve the above object, a coin hopper according to the present invention attaches a hopper body having a downwardly inclined bottom surface to a gantry, and drops a coin to an uppermost position on the bottom surface of the hopper body. A hole is formed on the bottom surface at a predetermined interval on the circumference for accommodating coins which are divided into one piece and accommodated therein, and a hole is provided between a starting end and an end of the accommodating hole. A disk provided with a non-hole portion wider than the opening pitch of the accommodation hole is rotatably mounted and made rotatable by a power source such as a motor,
Further, a baffle plate is mounted in the hopper main body so as to be rotatable up and down while being separated from the disk, and a detection sensor for detecting the amount of stored coins is provided on the peripheral wall of the hopper main body.

The mounting of the hopper body to the gantry may be fixed in a predetermined state, but the hopper body is mounted so as to be able to pivot up and down with respect to the gantry so that coins in the coin hopper can be easily removed. Is also good.

(Operation) According to the above means, the coin supplied to the hopper main body is restricted from flowing toward the disc by the baffle plate, and is properly accommodated in the accommodation hole of the disc. Then, the coin is ejected one by one from the coin drop hole due to the rotation of the disc, but since a non-porous portion is provided between the start end and the end of the accommodation hole formed in the disc, the circle is removed. A time for temporarily stopping the discharge of coins for each rotation of the plate is secured.

Further, since a detection sensor for detecting the amount of stored coins (remaining amount) is provided on the peripheral wall of the hopper main body, the supply amount of coins is controlled by the operation of the detection sensors.

(Effect of the Invention) Since the coin hopper of the present invention has the above-described structure, one of the discs for discharging coins from the hopper one by one.
With each rotation, a period of time during which coin ejection is paused is formed,
This makes it easy to adjust the timing at which coins discharged from the coin hopper are transferred to other transporting means, etc., and even if the timing is incorrect,
Since there is no coin ejection time for each rotation of the disc, adjustment can be performed easily.

In addition, since a baffle plate is provided in the hopper to restrict the flow toward the disk, the coins are securely stored in the storage holes of the disk, and the coins can be efficiently discharged.

Further, since a detection sensor for detecting the amount of stored coins is provided on the peripheral wall of the hopper main body, it is possible to supply coins by opening and closing a gate for supplying coins to the hopper based on a detection signal of the detection sensor. The quantity can be managed and controlled automatically.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a hopper body having a downwardly inclined bottom surface 2, and a peripheral wall facing the bottom surface 2 is also inclined toward the lowest point side of the bottom surface 2, and coins are positioned at the highest point of the bottom surface 2 of the hopper body 1. A disc in which a coin drop hole 3 slightly larger in diameter than the diameter of the coin a is opened and accommodating holes 5 for separating and accommodating coins a by one on the bottom surface 2 are provided at predetermined intervals. 4 is rotatably supported.

The hopper body 1 is fixedly joined to an inclined surface 6 'of a mounting frame 6 having a substantially triangular side surface, and both lower portions of the mounting frame 6 are rotatably moved up and down on shafts 8 and 8' on a frame 7. A locking means is provided which is supported and maintains the upright and down position.

In the locking means, an inverted L-shaped locking hole 9 is formed in the left and right side plates 7 ′ of the gantry 7, while a long hole 10 is formed in the side surface of the mounting frame 6.
A locking rod 11 is inserted transversely across the locking hole 9 and the elongated hole 10, and a spring hook engaged with the locking rod 11 and the rear portion of the mounting frame 6. A coil spring 13 is stretched across the rod 12.

Therefore, when the locking rod 11 is engaged with the rear end of the horizontal hole 9 ′ of the locking hole 9, the hopper body 1 is held upright,
11 is positioned at the upper end of the vertical hole 9 ″ of the locking hole 9 against the tensile force of the coil spring 13, and in this state, the mounting frame 6 is
Rotating downward around 8 ', the locking rod 11 is inserted into the vertical hole 9 ".
When the hopper main body 1 is engaged with the lower end of the hopper, the hopper main body 1 is held down in the state of the imaginary line in FIG.

A motor 14 is mounted on the back surface of the mounting frame 6, and the rotational force of the motor 14 is transmitted to a shaft 4 'fixed to the disk 4 via sprockets 15, 15' and a chain 16. Thus, the disk 4 is driven and rotated.

The disk 4 of the hopper body 1 perforates the accommodation holes 3 at predetermined intervals along the outer peripheral edge. A wide non-porous portion 17 is provided.

Above the disk 4, a baffle plate 18, which cuts off a part of the peripheral edge and forms an opening with the peripheral wall of the hopper main body 1, is mounted so as to be able to move up and down, thereby being supplied to the hopper main body. It is controlled that the coins a piled up become difficult to enter the accommodation hole 3 of the disk 4 as a pile.

Further, a plurality of through holes 19 are formed in the peripheral wall of the hopper body 1 in the depth direction, and a detection for detecting the remaining amount of the coin a supplied into the hopper body 1 is provided outside the through holes 19. A sensor 20 is provided, and the opening and closing of a gate (not shown) for supplying coin a to the coin hopper is controlled by a detection signal of the detection sensor 20.

In the figure, reference numeral 21 denotes a communication passage frame for transferring the coin a discharged to one sheet to another transportation means.

With the above configuration, the coin a supplied to the hopper main body 1 can be easily taken out by moving the hopper main body 1 relative to the gantry 7.
