Description

[Detailed Description of the Invention] Field of the Invention The present invention relates to a coin processing device in a vending machine or the like. The present invention relates to an improvement in a coin processing device having a temporary pooling means for temporarily pooling coins that have been used for a next transaction until the first coin for the next transaction is inserted.

Prior Art and its Problems A coin processing device 1 in a vending machine or the like as shown in FIG. A sorting means 5 having sorting and denomination passages 5a, 5b, and 5c temporarily stores the sorted coins 3 until the first coin for the next transaction is inserted, and also issues a sales cancellation command. a pooling means 7 for returning the coins to the receiving tray 6 when the coins are changed; a storing means 8 for storing the coins from the pooling means 7 as change; and a change conveyor such as a belt conveyor for conveying the coins from the storing means 8 to the receiving tray 6 as change. Means 9, and recovery means 1 for finally recovering coins
0 etc. are provided.

By the way, as shown in FIG. 2, the pool means 7 has storage sections 7a, 7b and 7c in accordance with the denominations in the pool block 7A, and the coins 3 are stored in storage chutes 7f and 7c as needed. 7g, 7h
A bottom plate 7B is provided for sorting to the return chute 7p, 7q, and 7r. As shown in FIG. 3, this bottom plate 7B protrudes at both ends through the substantially semicircular notches 11 shown in FIG. 4 provided in the partition plates 7M and 7N of the pool block 7A, Outside of frame 7C, the fifth
As shown in the figure, the disk plate 12 is rotated by a bottom plate rotating motor 14 via a drive shaft 13 about one upper corner 11a of the notch 11 as a fulcrum. This bottom plate 7B temporarily stores the coins used for the previous transaction until the first coin for the next transaction (hereinafter referred to as the first coin) is inserted into the coin slot 2. The limit switch SW1 is in a horizontal state as shown by the two-dot chain line in FIG. . In this state, when the detector 16 installed immediately after the coin input slot 2 shown in FIG. The bottom plate 7B is rotated in the direction of the arrow 17 (see Fig. 5), and the bottom plate 7B is moved to the storage side chute 7f, 7g, 7h via a roller 12a that is supported on the tip of the roller 12a.
It is rotated so that it opens. At this time, when the disk plate 12 hits the limit switch SW2, it is activated, and the power supply to the bottom plate rotation motor 14 is stopped, and the concave portion 1 formed in the disk plate 12 is stopped.
5 engages with a protrusion 18a of a leaf spring 18 attached to the frame 7C, thereby preventing movement of the bottom plate 7B. Then, after a time sufficient for the coins to fall into the storage chute 7f, 7g, 7h, which is measured by a timer (not shown), the bottom plate rotation motor 14 is driven in the opposite direction to move the coin to the storage chute 7f, 7g, 7h.
Disc plate 1 in the opposite direction of arrow 17 to close
Rotate 2. At this time, the engagement between the recess 15 of the disk plate 12 and the plate spring 18 is controlled by the bottom plate rotation motor 14.
is released by the rotational force of the disc plate 1.
The disk plate 12 is rotated until the roller 12b, which is rotatably supported by the disk plate 2, comes into contact with the upper end of the bottom plate 7B, and is further rotated until the bottom plate 7B becomes horizontal. When the limit switch SW1 detects that the recess 15 has returned to the home position, the power supply to the bottom plate rotation motor 14 is stopped, and the disk plate 12 is locked using a mechanical locking means similar to the leaf spring 18 (not shown). Depending on the bottom plate 7
B remains horizontal. Therefore, preparations for temporarily pooling the first coin and subsequent coins through the coin checking means 4 and the sorting means 5 are completed.

However, in such a pool means, the motor for rotating the bottom plate is stopped in the standby state for opening the storage chute or the return chute, so the leaf spring that maintains the bottom plate in an inclined state is Not only does this require a mechanical locking means, which complicates the structure, but it also takes a long time to restore the bottom plate to its horizontal state, including the time it takes for the disk plate to come into contact with the top edge of the bottom plate, and the time it takes to make the bottom plate horizontal after contact. Therefore, when the bottom plate rotating motor is operated at high speed, there is a problem that overrun occurs when the bottom plate returns to the horizontal position.

Purpose of the invention The present invention temporarily solves the problem of the pooling means in the conventional coin processing device, and uses an unreliable mechanical lock such as a leaf spring to maintain the bottom plate in an inclined state. It is an object of the present invention to provide a coin processing device having a pooling means that simplifies the configuration by eliminating the means, allows the bottom plate to be restored quickly, and prevents overrun when the bottom plate is restored horizontally. .

Means for Solving the Problems The present invention includes a storage section that temporarily holds the inserted coins on the bottom plate, and a constant biasing of the bottom plate in a direction that prevents the bottom plate from rotating toward the storage-side chute and the return-side chute. a spring, and a pooling means for rotating a bottom plate to sort coins into a storage side and a return side, the pooling device having a spring when the disk plate and the bottom plate are connected to the shaft thereof. , a motor for controlling the rotation of the bottom plate, a stopper for stopping the operation of the motor via the disk plate when the bottom plate is opened by driving the motor, a limit switch for detecting the position of the disk plate stopped by the stopper, and a first limit switch. a motor control means that receives a coin insertion signal and energizes the motor to rotate the bottom plate to bring the disk plate into contact with the stopper, and receives a limit switch signal and stops energizing the motor after a predetermined delay time; It is characterized by comprising the following.

Operation According to the present invention having such features, once the pooling means drives the motor in response to the first coin input signal, the disk plate and the bottom plate connected to the shaft thereof are rotated until they come into contact with the stopper. Then, even after the contact, the current is continued so that the coins held in the storage section are thrown into the storage chute or the return chute. The motor control means is supplied with an output from a limit switch which operates when the disk plate reaches a stop position by the stopper. Then, the motor control means controls the motor to stop energizing after the predetermined delay time has elapsed. When the motor is de-energized, the spring immediately returns the bottom plate to its original position.

Effects of the invention Therefore, according to the invention, since the motor continues to be energized when the storage section is opened, the bottom plate can be rotated without using a mechanical locking means such as a leaf spring. The lock mechanism can be simplified. Furthermore, since the motor is stopped when the bottom plate returns, overrun of the motor at the restoring position can be prevented. Furthermore, since it is returned by a spring, the return action can be made faster.
The effect is that the reliability of the pooling means can be improved once.

A spring 32 is provided that constantly biases the .

In the initial state of the coin processing device having the pooling means 7 having such a structure, the coins 3 used in the previous transaction are temporarily stored in each storage section 7a of the pooling means 7.
7b and 7c, the bottom plate 7B is held horizontally as shown by the solid line in FIG.
It is in a state where it is detected that the limit switch SW1 is at the home position of the disk plate 12. When a coin 3 for sale of the next product is inserted into the input slot 2 and the detector 16 detects the first coin, the signal shown in FIG. 10a is sent from the detector 16 to the input terminal 22 in FIG. A signal is inputted to the S input terminal of the RS type flip-flop via the Q output, and the bottom plate rotating motor 14 is driven via the driver 30 as shown in FIG. 10(d). At this time, the disk plate 12 reaches the solid line position in FIG.
It rotates against the spring 32 shown in FIG.
When the bottom plate 7B is rotated with the rotation of the disk plate 12 until it comes into contact with the stopper 21, the disk plate 12 operates the limit switch SW2.
