Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a mechanism for preventing coins from remaining in a coin feeding device that scoops up and sends out a large number of coins one by one that are received in bulk.

"Prior Art" Generally, in coin deposit machines, etc., a coin feeding device is used for the purpose of feeding a large number of mixed coins received at once to a coin discriminating section, etc., where they are discriminated, counted, etc. one by one. It is provided.

Conventionally, coin feeding devices have, for example, formed a hopper with a rotating disk in an inclined state and a hopper liner that covers the upper surface of the hopper, and transferred a large number of coins received into the hopper to a protrusion disposed on the periphery of the rotating disk. It is designed to scoop up each piece one by one and send it out.

``Problem that the invention aims to solve'' However, if the hot para liner that covers the rotating disk becomes statically charged, or if sticky foreign matter gets mixed in and adheres to the bottom of the hot para liner, small diameter coins such as one yen coins , a phenomenon in which lightweight coins are easily attracted to the surface of the hopper liner and remain at the bottom of the hopper without being retained by the protrusions of the rotating disk. In this case, it is possible to reduce the gap between the rotating disk and the hopper liner at the bottom of the hopper so that the coins can easily come into contact with the rotating disk, but if there are a large number of coins in the hopper, the coins may get stuck in the gap. A so-called jam is likely to occur, which may cause a decrease in supply capacity.

The purpose of the present invention is to provide a coin remaining prevention mechanism that can prevent coins from adsorbing to the hot paraliner, efficiently guide coins to the protrusions of a rotating disk, and improve the feeding capacity of a coin feeding device. shall be.

``Means for Solving the Problems'' The present invention involves receiving a large number of coins on a rotating disk arranged in an inclined state in a hopper, and using protrusions arranged on the periphery of the rotating disk to collect coins. A coin feeding device configured to scoop up and feed out coins one by one, comprising: a hotspar liner that covers the upper surface of the rotating disk; and a hotspar liner disposed below the hotspar liner so as to face the peripheral edge of the rotating disk. a plurality of through holes; a plurality of pin-shaped coin tipping members each having a spherical tip and inserted into each of the through holes so as to be able to move forward and backward toward the inside of the hopper; and each of the coin tipping members. an elastic member biasing the member from its rear end in a direction that causes the member to protrude into the hopper, and each of the coin knocking members has a distal end facing the rotating disk passing through a lower end of the rotating disk. It is characterized in that it is movably disposed until it protrudes from a vertical line toward the rotating disk.

"Function" In a coin feeding device having such a mechanism for preventing coins from remaining, when a large number of coins are put into the hopper, the weight of the stacked coins as they slide down to the bottom of the hopper causes the coin tipping member to is pressed and is moved back from inside the hopper while elastically deforming the elastic member, and when the number of coins in the hopper becomes small, the elastic member restores itself according to the weight of the coin that contacts the coin knocking member. A coin knocking member projects inward of the hopper and guides the coin toward the rotating disk. In this case, the coin tipping member moves until its tip protrudes toward the rotating disk from a vertical line passing through the lower end of the rotating disk, and pushes the upper part of the coin supported by the lower end of the rotating disk further than the lower end of the rotating disk. Guide it by turning it to the side. In this way, the coin knocking member is moved back and forth into the hopper as the number of coins increases or decreases in the hopper, and the distance between the rotating disk and the hopper liner is corrected to allow the rotating disk to smoothly scoop up coins. be.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

This coin feeding device has a hopper 3 that receives a large number of coins C, using a rotating disk 1 that is arranged in an inclined state with respect to the main body of a coin deposit machine, etc., and a hopper liner 2 that covers the upper surface of the rotating disk 1. The coins C received therein are sent out one by one by a rotating disk 1 and supplied to a coin discriminating section 4 and the like. That is, the rotating disk 1 is
A thin stepped portion 1a is provided on its peripheral edge, and protrusions 5 are provided on the surface of the stepped portion 1a at equal pitches in the circumferential direction to catch the coin C and scoop it up along the stepped portion 1a. It is made up of multiple locations. The height of the protrusion 5 is made smaller than the thickness of the coin C so that the protrusion 5 can catch the coins C one by one. On the other hand, the Hotsuparaina 2 is
The upper part of the hopper 3 has an opening 6 for receiving and sending out coins C, and the bottom part has an opening 6 for discharging deformed coins, etc., and covers the upper surface of the rotating disk 1, and the peripheral edge of the hopper 3 covers the upper surface of the rotating disk 1. The space between these peripheral edges is smaller than the outer diameter of the coin C, and the coins C are formed in a size that allows a plurality of coins C to be inserted in a stacked state parallel to the rotating disk 1. .

Further, at the outer bottom of the hopper 3, a hopper gate 8 for opening and closing the discharge port 7 is rotatably supported by a shaft 9. The hopper gate 8 has a link 10 integrally provided therein and a block 12 rotated by a drive motor 11 as shown by arrow A in FIG.
The pin 12b, which is provided eccentrically with respect to a, is slidably fitted into the elongated hole 10a of the link 10 and connected, so that the shaft 9 can be rotated in the direction shown by the arrow B in FIG. It is designed so that it can be rotated by rotating disk 1, and defective coins such as deformed coins are
When the coins remain at the bottom of the hopper 3 without being scooped up by the coins, the drive motor 11 is brought into operation to open the discharge port 7 to allow the defective coins to fall and be removed from the hopper 3.

A plurality of through holes 13 facing the peripheral edge of the rotary disk 1 are arranged in the lower part of the hotspara liner 2, and pin-shaped coin knocking members 14 are inserted into these through holes 13 so as to be able to move forward and backward. ing.
As shown in FIGS. 3 and 4, these coin knocking members 14 have their distal ends formed into spherical surfaces, and their proximal ends integrally connected to the outside of the hopper liner 2 by a plate 15. It is prevented from coming off inward, and is urged in the direction of protruding into the hopper 3 by an elastic member 17 such as a leaf spring fixed to the hopper gate 8 via a spacer 16 while in contact with the plate 15. . In the example shown in FIG.
It is made to protrude toward the rotating disk 1 side from a vertical line X passing through the lower end of.

In the coin feeding device configured in this way,
When a large number of coins C are inserted into the hopper 3, the coins C
A part of them forms a stack and falls to the bottom of the hopper 3. When these coins C come into contact with the coin folding member 14 protruding from the hot paraliner 2, the coin folding member 14 is pressed by the weight of the coins C, etc., and elastically deforms the elastic member 17 as shown in FIG. By retreating from inside the hopper 3 to the position indicated by the chain line, the movement of the coin C falling between the rotating disk 1 and the hopper liner 2 is not hindered, and the coin C is almost parallel to the rotating disk 1. I was guided to. On the other hand, when the number of coins C falling between the rotating disk 1 and the hopper liner 2 decreases, the weight of the coins decreases, and the coin knocking member 14 is pushed back by the restoring force of the elastic member 17 and moves toward the inside of the hopper 3. The coin C can be pushed toward the rotating disk 1 as shown by the arrow in FIG. That is, in this way, the coin knocking member 1 is adjusted according to the increase or decrease of the coins C in the hopper 3.
4 is moved forward and backward, the coin C is guided to the rotary disk 1 while correcting the distance between the rotary disk 1 and the hot paraliner 2 by the coin tilting member 14.

"Effects of the Invention" As explained above, according to the coin remaining prevention mechanism in the coin feeding device of the present invention, the following effects can be achieved.

(i) A through hole was provided in the lower part of the hopper liner facing the peripheral edge of the rotating disk, and a coin knocking member biased by an elastic member in the direction of protruding into the hopper was inserted into the through hole so as to be able to move forward and backward. from,
Since the coin knocking member is moved forward and backward into the hopper while elastically deforming the elastic member according to the weight of the coin pressing the coin knocking member, the distance between the rotating disk and the hopper liner can be adjusted according to the increase or decrease of coins in the hopper. The coins can be reliably guided to the rotating disk through correction by the coin tipping member, and the coins can be scooped up smoothly by the rotating disk, thereby improving the coin supplying ability. in this case,
The coin tipping member moves until its tip protrudes toward the rotating disk from a vertical line passing through the lower end of the rotating disk, thereby tipping the upper part of the coin supported by the lower end of the rotating disk toward the rotating disk from the lower end. In this way, coins can be reliably guided.

() Even if static electricity such as hot paraliner or sticky foreign matter is mixed in,
The coin knocking member protruding into the hopper can contact the coin and prevent the coin from adhering to the lower surface of the hopper liner, and can forcefully guide the coin toward the rotating disk.

() Furthermore, it is possible to prevent coin jamming at the bottom of the hopper, and also to prevent coins from adhering to the hopper liner side.

() Also, since the structure is such that the coin tipping member is only held down from the rear end by an elastic member,
The biasing mechanism for the coin knocking member can be simplified and the size can be reduced.
