Description

[Detailed description of the invention] This invention discharges the product by rotating the operating part in one direction,
This relates to a vending machine that, when rotated in the other direction, ejects the correct coins stored in the coin storage mechanism or the incorrect coins inserted.The product is ejected depending on the rotation state of the operating section provided on the surface of the machine. It is designed to eject the correct coins and incorrect coins that have been inserted.

Therefore, if a product purchaser inserts a valid coin and then cancels the product purchase, or if he or she accidentally inserts an incorrect coin, he or she can immediately eject the inserted coin by rotating the operation unit, and the product can also be removed. It can be discharged with a simple operation.

The present invention will be explained below with reference to the illustrated embodiment.A vending machine has an operating part 2 on the surface of a machine frame 1, a core shaft 3 is horizontally provided inside, and a playable device is mounted on the end of the core shaft 3. The cylindrical shaft 4 and the rotating shaft 5 of the operating section 2 are connected by a rotation transmission mechanism 6.

The rotation transmission mechanism 6 includes a worm gear 7 provided at the tip of the rotating shaft 5 and a worm gear 7 formed on the circumferential surface of one end of the cylindrical shaft 4.
It is shown as a worm wheel 8 meshing with the operating part 2.
When the operating section 2 is rotated in one direction, the cylinder shaft 4 is rotated in one direction via the rotation transmission mechanism 6, and when the operating section 2 is rotated in the other direction, the cylinder shaft 4 is rotated in the other direction.

A coin holding board 9 is provided at the other end of the cylinder shaft 4.

As is well known, this coin holding board 9 is made up of three plate materials stacked together, and coin sockets 10 and 10 are opened on the outer periphery so as to face each other in the radial direction. Stotsuba 11
to protrude.

Then, the locking part 13 of the first locking frame 12, which is pivoted at one end, is made to face the socket 10 that opens above the coin holding board 9, and the socket 10 is connected to a coin sorting machine (not shown). The lower end opening 15 of the falling gutter 14 for the falling proper coins is located.

On the other hand, a ratchet disk 16 and a cam disk 17 are provided at the end of the core shaft 3.
and the eccentric cam disk 18 are fixedly provided, and the ratchet disk 16
Claw receiving pieces 1 6', 1 6' cut and raised on one side of the
face the claws q and 9' provided on one side of the coin holding board 9.

Therefore, the rotation of the coin holding board 9 is such that the claw piece q is rotated by the receiving claw piece 16.
' in the direction of pressing (in the direction of the arrow in Figure 4, hereinafter referred to as the first rotation direction), the holding plate 9 and the ratchet plate 16 are rotated together by the pawl piece 9' and the receiving pawl piece 16', and the center is pressed. By rotating the shaft 3, the rotation of the holding board 9 causes the claw piece 9' to move to the receiving claw piece 16'.
In the direction away from the rotation direction (in the direction of the arrow in FIG. 5, hereinafter referred to as the second rotation direction), the holding plate 9 rotates independently and does not rotate the ratchet plate 16 and the core shaft 3.

A cut arrow part 19.19 is formed on the periphery of the ratchet board 16 at a position corresponding to the socket 10 of the coin retaining board 9, and a stopper 20 is provided protruding from one end of the notch part 19. A locking portion 22 of a second locking frame 21 having one end pivoted thereon faces.

Since the head 23 of the second locking frame 21 is hooked on the first locking frame 12, the second locking frame 21 tilts in the same manner as the first locking frame 12.

Therefore, the ratchet plate 16 is connected to the locking portion 2 of the second locking frame 21.
2 is engaged in the notch 19, it is locked by the stopper 20 and the first ratchet tooth and cannot rotate, but the second
When the locking frame 21 moves upward and the locking portion 22 is disengaged from the cutout portion 19, it can rotate.

The cam disk 17 urges the rotation of the ratchet disk 16 and the core shaft 3, and presses the roller 25 at the tip of the pressing frame 24, which has one end pivoted on the outer edge, and when the core shaft 3 rotates, the roller 25 rotates normally. Stop at the position.

Further, when the core shaft 3 and the eccentric cam disk 18 rotate, they actuate a product discharging mechanism or a change discharging mechanism (not shown).

The tip of the swinging claw 26 is pressed against the lower outer edge of the coin holding board 9, the base end of the swinging claw 26 is pivoted to one end of the rotating plate 27, and the other end of the rotating plate 27 is linked. A mechanism 28 connects to the lower end of the operating rod 29 .

The upper end of the operating rod 29 is connected to a coin sorter (not shown), and when it descends, it operates the coin sorter and causes the inputted invalid coins to flow down to the discharge port.

Since the present invention is constructed as described above, the following operations are used to discharge products or to discharge valid coins or invalid coins by this vending machine.

When a purchaser inserts a proper coin into the slot to purchase a product, the coin flows out from the lower end opening 15 of the drop gutter 14, passes through the socket 10 of the coin holding board 9, and is held therein.

When a certain number of coins are stored inside, the upper half of the final coin α protrudes from the socket 10 and covers the edge of the stopper 11.

In this state, the purchaser moves the operation unit 2 in one direction (for example, right direction).
When the coin holding plate 9 is rotated in the first rotation direction via the rotation transmission mechanism 6, the ratchet plate 16 is rotated in the same direction due to the contact between the pawl piece 9' and the receiving pawl piece 16' as described above. Rotate in the direction.

Due to the rotation of the coin holding board 9, the locking part 13 slides up the outer circumference of the coin α, the first locking frame 12 moves upward, the locking part 13 passes over the stopper 11, and at the same time, the second locking frame 21 moves up. The locking portion 22 is moved to be located above the stopper 20.

Therefore, the coin holding board 9 and the ratchet board 16 can be largely rotated in the first rotation direction by the operation unit 2,
Moreover, the rotation of the ratchet disk 16 causes the cam disk 17, the eccentric cam disk 18, and the core shaft 3 to rotate.

When the coin storage board 9 rotates 180 degrees in this way, the coins stored inside fall under their own weight and are stored in the safe.
At the same time, products and change are discharged by the core shaft 3 and eccentric cam disk 18.

Further, the roller 25 enters the recessed part of the cam disc 17 to stop the rotation of the ratchet disc 16, etc., and the first locking frame 1
The locking part 13 of the second locking frame 21 locks into the receptacle 10, and the locking part 22 of the second locking frame 21 locks into the notch 19, respectively, to stop the free rotation of the coin retaining board 9 and the ratchet board 16.

On the other hand, if an incorrect coin is inserted into the slot, or if a correct coin is inserted but the purchase of the product is canceled, the operation unit 2 may be rotated in the opposite direction (for example, to the left).

In other words, the incorrect coins inserted remain inside the coin sorter,
Appropriate coins are stored inside the coin storage board 9.

In this state, when the operation unit 2 is rotated in the opposite direction and the coin holding board 9 is rotated in the second rotation direction via the rotation transmission mechanism 6, the stopper 11 is not obstructed by the first locking frame 12, so the coins are held. In the board 9, the claw piece 9' separates from the receiving claw piece 16' and rotates independently, and when it rotates by a certain angle, the appropriate coins inside fall under their own weight and are discharged to a return opening or a product removal opening.

When the coin holding board 9 rotates sufficiently in the second rotation direction, the stopper 11 presses the swinging pawl 26 to rotate the rotating plate 27 (Fig. 5), and the link mechanism 28 lowers the operating rod 29. Then, the unsuitable coins in the coin sorting machine are discharged to the return slot or product takeout slot.

Note that if the operating section 2 is energized so that it rotates back when turned in the second rotation direction, the operating section 2 and the coin holding board 9 will return and rotate as soon as you release your hand from the operating section 2 after the coin is ejected. Then, the claw piece 9' comes into contact with the claw receiving piece 16' and stops, so that the coin receiving opening of the coin holding board is in a condition to accept coins.

As is clear from the above, according to the present invention, when the operating section is rotated in one direction, the product is ejected, and when the operating section is rotated in the other direction, the inserted coins are ejected. Unlike other vending machines, there is no need to provide a coin return lever, which simplifies the internal structure.

In addition, even after inserting a predetermined number of proper coins, if you wish to cancel the purchase of the product, you can eject the proper coins, which is convenient for the product purchaser.
Moreover, it has high practical value because it can be incorporated into any vending machine that handles any kind of product.
