Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention uses centrifugal force to move coins supplied to the upper surface of a rotating disk to the periphery and outward from the periphery of the rotating disk. The coins are fed into a coin passage provided towards the coin passage, and the coins are fed into the coin passage by a conveyor belt located at the top of the coin passage. The present invention relates to a coin feeding device that can prevent clogging in the coin feeder.

(Prior Art) In a conventional coin feeding device, an entrance part of a coin passage is formed at the starting ends of the first and second passage members, and a pulley on the starting end side of the conveyor belt is located at this entrance part. The first,
Each starting end of the second passageway member is located. When two coins enter the entrance of the coin passage in a state where they collide in the radial direction, the first and second passage members are in fixed positions and the conveyor belt feeds the coins into the coin passage. As a result, the two coins colliding with each other are moved as if they were interlocked, causing a coin jam at the entrance of the coin passage.

Therefore, in the past, an arm was provided along the circumferential direction of the rotating disk from the entrance of the coin passage, and this arm was configured to be moved inward of the rotating disk by a driving means such as a solenoid. When a coin jam occurs, the operator can visually check the condition and press the clear button, or a detection switch installed at the entrance of the coin passage detects this and moves the arm inward to the rotating disk. By doing so, the coins were pushed out, thereby releasing the coin jam.

(Problem to be solved by the invention) However, in the conventional device described above, the coin is cleared after the coin becomes stuck at the entrance of the coin passage. It is inevitable that the supply of coins will be stopped for the time required to process the coins, and in recent years there has been a growing demand for coins to be processed at particularly high speeds, so the above-mentioned loss time has become a major problem.

In view of this, the present invention has been devised for the purpose of providing a coin feeding device that can automatically eliminate coin jams that occur at the entrance of a coin passage.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, the present invention is arranged on the upstream side in the rotational direction with respect to the coin delivery peripheral area of the rotating disk and is swingable around a pivot point on the starting end side in the coin passage direction. a swinging member having a guide edge that guides the coin from the periphery of the rotating disk into the coin passage;
The conveyor belt has a starting end pulley located on the side of the guide side edge of the swinging member, a starting end located near the starting end pulley, and a side edge continuous with the guide side edge of the swinging member. A first passage member for regulating the width of the coin passage, and a starting end having a sliding part such as a rotor located downstream from the starting end of the first passage member in the direction of the coin passage, and both starting ends serve to control the width of the coin passage. a second passage member that opposes the first passage member and regulates the width of the coin passage; The structure includes a biasing spring means and an engaging portion that restricts the swinging of the swinging member due to the biasing force of the spring means.

(Function) With the above configuration, when two coins enter the entrance of the coin passage at the same time, the outer circumferential surface of the coin pushes open the swinging member, and the coin is conveyed by the conveyor belt, and the outer circumference of the coin being conveyed. The other coin is pressed against the sliding portion and is repelled onto the rotating disk.

(Embodiments) The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a plan view showing an embodiment of the present invention. In the figure, 1 is a rotating disk, and a coin passage 2 is provided in the tangential direction of the disk.

The coin passage 2 has left and right first and second passage members 3, 4 that determine the width of the passage, and engagement edges 5, 6 protruding from the lower portions of opposing side edges of these passage members 3, 4. The upper surface is used as a coin sliding surface, and the gap between the engaging edges 5 and 6 is used as an exclusion groove 7 for dropping and ejecting coins having a smaller diameter than a predetermined coin.

The entrance portion 2A of the coin passage 2 formed at the starting ends of the first and second passage members 3 and 4 has a surface that is the same as the upper surface of the peripheral edge of the rotating disk 1 and the upper surface of the engaging edges 5 and 6. A bottom plate 8 is provided.

Further, a swinging member 10 is provided on the upstream side in the rotational direction with respect to the coin sending peripheral area of the rotating disc 1 (a peripheral part of the rotating disc that sends out coins to the entrance portion 2A of the coin passage 2). Side edge 10A
(the side edge that serves to guide coins to the entrance portion 2A)
is provided.

That is, the passage member 3 is fixed at a position that does not reach the periphery of the rotary disk 1, and the swinging member 10 is positioned between the periphery of the rotary disk 1 and the end of the passage member 3. In this embodiment, the guide side edge 10A and side edge 3A of the swinging member 10 and the first passage member 3 are provided substantially tangentially to the circumferential edge of the rotary disk 1.

The starting end of the other passage member 4 is fixed at the peripheral edge of the rotating disk 1, and a rotor 11 such as a bearing is attached to the starting end to form a sliding part, so that when a coin comes into contact with it, it smoothly slides. The coin passage 2 is made to enter the entrance portion 2A of the coin passage 2. Note that this rotor 11 does not necessarily rotate, but may be a fixed member as long as it allows good sliding with coins.

The swinging member 10 has a pin 12 at the end opposite to the passage member 3 (pivot part on the starting end side in the coin passage direction).
The other end of the swinging member 10 is supported rotatably in a horizontal plane, and a stopper 13 formed integrally with the swinging member 10 is provided at the other end. When engaged by the bias of the spring 14, the swinging member 10
The guide side edge 10A is the side edge 3A of the passage member 3.
It is arranged so that it is placed on the same plane as the

At the upper part of the coin passage 2 along the passage direction, there is a conveyor belt 15 that contacts the upper surface of the coins on the passage 2 and conveys the coins, and a start end pulley 16,
The rear end pulley 17 is wound and tensioned so as to be rotatable. be located. Further, the starting end of the first passage member 3 relative to the starting end side pulley 16 is located near the pulley 16 in the coin passing direction or at a downstream position. The starting end of the second passage member 4 (rotor 11 in the illustrated example) is located downstream from the starting end pulley 16 and the starting end of the first passage member 3.

Next, the operation of the present invention will be explained with reference to FIG.

When the coins supplied onto the rotating disk 1 are aligned with the periphery due to the centrifugal force caused by the rotation of the rotating disk 1 and reach the entrance 2A of the coin passage 2 in an aligned state, the upper surface of the bottom plate 8 and the lower surface of the conveyor belt 15 are aligned. During this time, small diameter coins fall from the sorting groove 7 and are removed, and only the designated coins reach the end of the coin passage 2. transported.

Coins may get jammed when entering the entrance portion 2A of the coin passage 2 from the rotating disk 1. The condition that causes poor flow of coins at the entrance portion 2A is as follows:
Referring to FIG. 2, the center _O1 of the preceding coin _C1 is the center 11a of the rotor 11 and the center of the next coin _C2.
This is the case where the entrance section 2A is placed on the side of the entrance section 2A from the line A connecting with _O2 . In other words, coin C ₂ is transferred to conveyor belt 1
A force acts to force the coin C 1 to enter under the pulley 16 of No. 5 and be conveyed into the entrance section 2A, and since the center O ₁ of the coin C ₁ is on the entrance section 2A side from the line A, this coin C ₁ also enters the entrance section 2A. Although it tries to enter 2A, it hits the side of the conveyor belt 15 and cannot enter, and the flow stops.

Therefore, in the conventional case, the coins C ₁ and C ₂ are stuck against each other and neither can move, and the jammed state cannot be released unless an external force is applied.

However, in this invention, coins are
When C ₁ and C ₂ are pressed against each other, one end of the coin C ₂ hits the side edge 10A of the swinging member 10, and the force of the coin C ₂ being conveyed by the conveyor belt 15 pushes the coin C 2 against the swinging member. 10 is pushed away as shown by the chain line against the spring 14, whereby the coin _C2 is conveyed by the conveyor belt 15 and advances to position B as shown by the chain line. When this state is reached, the center 11a of the rotor 11
Since the center O ₁ of the coin C ₁ is located on the opposite side of the entrance part 2A from the line A′ connecting the center O ₂ of the coin C ₂ and the center O 2 of the coin C 2, the coin C ₁ moves toward the center of the rotating disk 1. Only the coin _C2 is pushed out and enters the entrance portion 2A.

[Effect of idea]

Therefore, according to the present invention, even if two coins enter the entrance of the coin path at the same time, the tension between the coins is automatically released without applying any external operating force, and the tension between the coins is automatically released without applying any external operating force. Since the coins are fed one by one into the coin passage, an excellent effect can be obtained in that the phenomenon of coin jamming at the entrance can be eliminated.
