Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin dispensing device consisting of a hopper and a dispensing device main body provided below the hopper, and is used in, for example, a currency exchange machine, a change dispensing machine, a vending machine, etc. It handles coins and coins that are gaming media for gaming machines.

"Prior art" As a conventional coin sending device, for example,
Some of these are disclosed in Japanese Patent Application Laid-Open No. 49-70696 and Japanese Patent Application Laid-Open No. 49-34895.

That is, Japanese Patent Application Laid-open No. 49-70696 discloses a device that continuously aligns and transfers coins on a rotating disk, the rotating disk rotates only in the forward rotation direction, and a corresponding processing flow path is provided. something is disclosed.

Further, Japanese Patent Application Laid-Open No. 49-70696 discloses a technique for reversing a rotating disk by operating a manual switch after receiving a coin jam signal.

``Problems to be Solved by the Invention'' However, with such conventional coin dispensing devices, when coins are processed continuously, there is a risk that concentrated coins may stick together and cause a so-called bridge phenomenon. Once the bridging phenomenon occurs, it is not easy to eliminate it simply by reversing the rotating disc, and in some cases requires disassembly and repair. There was a problem that the operating rate of machines etc. decreased.

The present invention has been made by focusing on such conventional problems, and provides a coin dispensing device that can input and process a large amount of coins at once, and that can be easily recovered even if a bridge occurs. It is intended to.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is, in a coin dispensing device comprising a hopper and a dispensing device main body provided below the hopper, said dispensing device main body. has a rotating disk supported horizontally or at a slight inclination, and a discharge passage facing the outer periphery of the rotating disk and disposed substantially tangentially and sealed to such an extent that coins do not fly out; A reversing disc is provided which rotates integrally with the reversing disc, and a reversing mechanism is provided which temporarily engages the outer periphery of the reversing disc to rotate it in the opposite direction, and the reversing disc is operated by temporarily stopping the rotating disc. This coin dispensing device is characterized by being able to freely rotate and then reverse rotation.

"Operation" A coin put into the hopper is ejected onto the rotating disk, and the coin moves to the outer periphery of the rotating disk due to rotational force and centrifugal force.

The coins that have moved to the outer periphery are aligned, guided to the discharge path, and discharged.

If a bridging occurs, the rotating disk is temporarily stopped and allowed to rotate freely. It absorbs the repulsive force of the coin that is bridled during this free rotation, and when the reversing mechanism is operated, it rotates extremely smoothly in the reverse direction.
A portion of it temporarily engages the reversing disk to reverse the rotation.

As a result, the rotating disk is reversed, and the rotating disk is displaced in the opposite direction to the direction in which the bridging occurred, so that the bridging is resolved and collapsed.

Even if the operation of the reversing mechanism is stopped and the rotating disk is driven in the normal rotation direction, the once collapsed bridge will not be reproduced and it will be able to operate smoothly again.

Since the reversing mechanism does not engage with the rotating disk when it is not being operated, it does not interfere and create resistance.

"Embodiments" Various embodiments of the present invention will be described below based on the drawings. Note that similar parts in each embodiment are designated by the same reference numerals, and redundant explanation will be omitted.

1 and 2 show one embodiment of the invention.

The coin dispensing device 10 consists of a hopper 20 and a dispensing device main body 30 below it.

The hopper 20 is funnel-shaped with an opening 21 opening upward, and the upper part forms a storage space 22 in which coins A are stored.

A guide surface 24 that directs the flow of coins A toward one side wall 23 is provided at the bottom of the storage space 22, and a flow path extending from the guide surface 24 to a flow path cover 24a that is slightly higher forms a first flow path 25. A second flow path 26 is formed diagonally downward from the side wall 23, and a discharge port 27 is provided at the end of the second flow path 26. The flow of coin A is now regulated.

The rotating disk 40 has an outer diameter slightly smaller than the inner circumference of the peripheral wall 32 of the housing 31. A friction plate 41 is attached to the center of the surface, and a hub 42 formed on the back side is connected to the drive shaft 36 of the motor 35. It is fixed in. A belt hook groove 43 is provided on the periphery of the rotating disk 40.
is engraved, and a belt 43a that distributes driving force to a discharge path (not shown) is wound around it. Further, the rotating disk 40 is supported pivotably at an angle of 0 degrees (horizontal) to approximately 30 degrees.

The discharge port 27 of the hopper 20 is open toward one side of the surface of the rotating disk 40, and the valve spring 2 blocks the discharge port 27 and regulates the flow of the coins A.
7a is arranged, facing the discharge direction of the discharge port 27,
A baffle plate 28 is fixed to the lower surface of the guide surface 24.

A locking protrusion 44 protruding from the center of the rotating disk 40
The base of the stirring rod 45, which is elastically deformable, is solidified, extends into the first flow path 25 in the hopper 20, and its tip is locked to a locking bracket 45a fixed to the hopper 20. An opening through which a stirring rod 45 passes is formed in the channel cover 24a.

The stirring rod 45 is a tightly wound coil spring, and is set to have enough elasticity to swing around among the many coins A in the hopper 20, rather than simply rotating around the central axis. Stirring rod 45
The middle part is bent into a substantially C-shape to form a stirring part 46.

Various selection plates (not shown) are installed facing the outer edge of the rotating disk 40, and then the rotating disk 4
A discharge path (not shown) is provided in a substantially tangential direction of zero.

A reversing mechanism 50 is provided for the rotating disk 40.

In the reversing mechanism 50, a reversing disk 51 is fixed to the drive shaft 36 of the motor 35.
6 and the swing lever 52 that is loosely fitted into the swing lever 52.
A claw lever 53 and a handle lever 54 are respectively connected to the ends of the claw lever 53 and a handle lever 54, and a connecting lever 5 is connected to the other end of the claw lever 53 and the handle lever 54.
A four-bar linkage mechanism 56 consisting of 5 is provided.

A knurling 51a is carved on the outer periphery of the reversing disc 51, and a pawl 53a at the tip of the pawl lever 53 faces the knurling 51a.

The four-bar link mechanism 56 is biased in one direction by a tension spring 57, and has an operating handle 54a at the end of the handle lever 54, and when the operating handle 54a is opened, the claw 53a of the claw lever 53 is arranged so as to be spaced apart from the knurling 51a of the reversing disc 51.

Next, the action will be explained.

When the motor 35 is started, the rotating disk 40 is driven to rotate in the forward direction shown by the solid line in FIG.
3a drives the belt conveyor in the discharge path in the feeding direction. The reversing mechanism 50 is not operated as long as the rotary disk 40 is rotating smoothly, and the claw 5 of the claw lever 53 is moved by the biasing force of the tension spring 57.
3a is held apart from the knurling 51a of the reversing disc 51, and does not interfere with or create resistance.

When a coin A is inserted through the opening 21 of the hopper 20, the coin A is temporarily stored in the storage space 22, passes through the first channel 25 on the guide surface 24, heads toward the side wall 23, bends there, and enters the second channel. 26, the coin A is discharged from the discharge port 27 onto the upper surface of the rotating disk 40 while the momentum of the flow is suppressed.

Inside the hopper 20, the stirring rod 45 rotates into the rotating disk 40.
The coin A is swung around at the same rotational speed to prevent the coin A from bridging, and the coin A is continuously sent to the discharge port 27 without causing a breathing phenomenon. At the outlet 27, a valve spring 27a regulates the flow of coins A.

The discharged coin A is repelled outward by centrifugal force on the upper surface of the rotating disk 40 and moves around on the rotating disk 40. While moving around, the coins A reach the selection plate, are aligned toward the discharge path, are conveyed, and are discharged.

When trouble occurs in the bridge, the rotating disk 40 is temporarily stopped and allowed to freely rotate.

When the operating handle 54a of the handle lever 54 of the reversing mechanism 50 is pulled forward, the connecting lever 55 is displaced, and the pawl 53a of the pawl lever 53 moves forward while approaching the knurl 51a of the reversing disc 51, temporarily. to engage. When the pawl 53a is further displaced, the reversing disk 51 rotates as shown by the broken line in FIG. 1, and the rotating disk 40 also rotates in the reverse direction as shown by the broken line.

Rotating disk 4 in the opposite direction to the direction in which the bridging occurred.
Since 0 is displaced, the coins that were bitten are pulled apart, and the bridge is broken and resolved. Since bridging occurs due to chance factors, it does not return to the state before the bridging, and the rotating disk 40
Even if the bridge is driven in the normal rotation direction, the once collapsed bridge will not be reproduced and it can be operated smoothly again.

When the operating handle 54a is released, the reversing mechanism 50 returns to its original state due to the biasing force of the tension spring 57, and as described above, the pawl 53a of the pawl lever 53 is maintained in a state separated from the knurling 51a of the reversing disc 51. be done.

When the coin dispensing device 10 is operating smoothly, the claw portion 62 of the operating lever 60 is connected to the reversing disk 51.
It is spaced apart from the knurling 51a. If bridging occurs, when the operating handle 61 is held and the operating lever 60 is rotated, the pawl portion 62 engages with the knurling 51a of the reversing disc 51 to reverse the reversing disc 51, thereby rotating the rotating disc 40. It is a reversal.

FIG. 5 shows a third embodiment, in which the claw portion 62 of the operating lever 60 is replaced with an engaging surface 62a that engages with the knurl 51a of the reversing disc 51. When the operating lever 60 is operated, the engaging surface 62a comes into pressure contact with the knurl 51a of the reversing disc 51 and rotates it.
