Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a coin dispensing device, and more particularly, to a device for dispensing coins, medals, etc. one by one.

(Prior Art) As a conventional coin dispensing device of this type, for example, the structure described in Japanese Patent Publication No. 55-48634 is known. In this structure, a coin feed disk, which has multiple coin feed circular holes formed on the same circumference at the center, is fixed to a rotating shaft protruding from the base plate by screwing from the center shaft hole, and the coin feed disk is fixed to the rotating shaft protruding from the base plate. The annular ring is fixed to the base plate by engagement with the protrusion and the engagement hook,
The coins supplied into the ring by the rotation of the disk are dropped into the circular hole of the disk, and the coins are pushed by a pushing protrusion formed on the lower surface of the disk, and then released from the ejection opening formed in the ring. A structure is adopted to derive coins.

(Problems to be Solved by the Invention) The conventional device described above has a structure in which the ring is fixed to the base plate by engagement with the protrusion and the engaging hook part, and the coin feed disk is fixed and supported on the rotating shaft. If multiple coins enter the coin feeding circular hole of this coin feeding disk in an inclined manner, the coins will be caught between the base plate and the coin feeding disk, easily deforming the coin feeding disk, and damaging the entire device. In addition, the distance between the base plate and the disk and the height of the coin ejection opening of the ring are limited to a certain value. Yen coin dispenser, 100 yen coin dispenser, and
In order to change the distance between the base plate and the disk and the height of the coin ejection opening, such as in a 500 yen coin dispenser, the disk and ring must be changed depending on the type of coin, which reduces productivity. However, it has the problem of lacking versatility.

The present invention has been made in view of the above-mentioned problems, and is made by deforming the coin feeding disk due to the weight of the coins on the coin feeding disk and obliquely entering a plurality of coins into the coin feeding circular hole of the coin feeding disk. This is a highly versatile coin dispensing device that prevents deformation of the coin feeding disk, eliminates the risk of damage to the entire device, and can be applied to various types of coins with simple adjustments depending on the thickness of the coin. The purpose is to provide.

[Structure of the invention]

(Means for Solving the Problems) The coin dispensing device of the present invention includes a base plate, a rotating shaft rotated by an electric motor, a coin feeding disk, a lower ring, and an upper ring, A rotating shaft is provided on the base plate side, and the coin feeding disk has a plurality of circular holes for coin feeding, the centers of which are formed on the same circumference, and is connected to the rotating shaft in the direction of rotation thereof. The lower ring is disposed between the coin feeding disk and the base plate and is in contact with the outer periphery of the lower surface of the coin feeding disk to rotate the coin feeding disk. A coin dispensing port is formed in the circumferential surface of the coin feeding disk for rotatably supporting a plurality of rollers rotated by the rotation and for discharging coins fed through the coin feeding circular hole of the coin feeding disk, and the upper ring is connected to the coin feeding disk. The rollers of the lower ring and the upper ring are rotatably supported by a plurality of rollers which are disposed on the upper part of the coin feed disk and are in contact with the outer periphery of the upper surface of the coin feed disk and are rotated by the rotation of the coin feed disk. a coupling means for coupling the lower ring and the upper ring so as to rotatably sandwich the coin feeding disc between the rollers; fixing means for fixing the upper ring and/or the lower ring to the base plate; and the lower part. The present invention is characterized by comprising an adjusting member selectively interposed between the ring and the base plate and capable of adjusting the gap between the base plate and the lower ring.

(Function) In the coin dispensing device of the present invention, when the rotating shaft is rotated by the drive of the electric motor, the coin feeding disk rotates while being sandwiched between the rollers supported by the upper ring and the lower ring, respectively, and the coin feeding disk rotates. The coin on the disk falls into the circular hole and enters the gap between the coin feed disk and the base plate.The coin is moved by the rotation of the coin feed disk, and when it reaches the position of the coin ejection port, the coin is removed from the coin ejection port. Sent out. Even if the weight of the coin supplied to the coin feeding disk is large, or even if the coin enters the circular hole of the coin feeding disk diagonally, the coin feeding disk will be held between the rollers of the upper ring and the lower ring. Since the coin feeding disc is rotated by the coin feeder, the coin feeding disc does not deform.Furthermore, an adjusting member can be selectively inserted between the lower ring and the base plate to adjust the distance between the base plate and the disc and the height of the ejecting port. The thickness can be adjusted according to the thickness of the coin.
