Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a product dispensing device for a spiral type vending machine arranged vertically.

(B) Conventional technology Conventionally, this type of product delivery device has a drive shaft with a spiral member wrapped inside a product storage column that has an opening for loading products on the front and an outlet for delivering products on the bottom. It is generally known that the product is placed in the vertical direction, the product is inserted and supported from the front opening into the gap between the spiral members, and the product is moved downward by a predetermined rotation of the drive shaft and delivered from the lower end of the spiral member through the delivery port. For example, Utility Model No. 57-137079
It is shown in the publication No.

(C) Problems to be Solved by the Invention The spiral type product delivery device having such a configuration has a structure in which the product is inserted and supported in the gap formed between the helical sides of the helical spiral member. is housed and supported in the gap between the spiral members in an inclined state so that one end is directed downward toward the outlet. Further, since the spiral member is formed of a wire-like member and the gap interval is wider than the thickness of the product, the product can move very freely within the gap. That is, since the spiral member is uniquely formed in a spiral shape, the gap is narrow on the drive shaft side and widens outward from the drive shaft side. Therefore, since the distance between the helical sides must be made sufficiently larger than the thickness of the product, the stored product has a large degree of freedom within the gap, and this degree of freedom tends to increase as the product to be stored becomes larger. It is in. If this degree of freedom is large, there is a drawback that the product stored and supported in the lowest gap is easily pulled out of the delivery port, and may fall due to vibration or the like and be delivered incorrectly. Therefore, it is not possible to store and sell large products using a spiral type product delivery device, and the sale of large products requires the use of a complicated and expensive chain elevator type product delivery device.

In view of the above, the present invention provides a device that can reliably prevent tampering even with large products and can reliably deliver the products.

(d) Means for Solving the Problems To explain the present invention, a product from the spiral member 8 is transferred to a lower position of the spiral member 8 and placed and supported, and the product is transferred to the delivery port 3 by rotation of the drive shaft 6. A delivery board 11 is provided which sends out the product by opening the delivery board 11, and is provided at an intermediate portion between the delivery board 11 and the spiral member 8, and is pressed and rotated by the product placed on the delivery board 11 to send out the product. This configuration includes a regulating member 14 that opens the outlet 3 and locks the outlet 3 in a closed state when the pressure from the product is released by opening the outlet 3 of the outlet plate 11.

(E) Function In the present invention, the delivery plate opens the delivery port by the rotation of the drive shaft and delivers the product on the delivery plate, and after the delivery plate returns to rotation, the product is transferred from the lower end of the spiral member onto the delivery plate. At the same time, when the delivery port is opened by the delivery plate, the delivery port is closed by the regulating member.

(F) Embodiment The drawing shows a product dispensing device according to an embodiment of the present invention, in which 1 is a substantially box-shaped product storage column provided inside the vending machine main body, and has an opening 2 for loading products on the front side.

This is a delivery plate that is rotatably supported on a shaft 12 installed between A and 1B, and can open and close the delivery port 3, and the support member 10 extends into the delivery port 3 to open and close the bottom surface 11A of the delivery plate 11. By being positioned corresponding to , downward rotation is prevented and supported in a substantially horizontal state.

13 is provided across the front and rear walls 1A and 1B,
As shown in FIG. 2, this is a partition plate that substantially closes the area below the spiral member 8 on the right side of the drive shaft 6, except for the movable range of a locking member 20, which will be described later.

Reference numeral 14 designates a regulating member as a theft prevention plate provided at an intermediate portion between the spiral member 8 and the delivery plate 11, and includes a closing portion 14A that closes the delivery port 3 and a regulating portion 14B that abuts against the stopper portion 13A of the partition plate 13. The regulating portion 14B is rotatably supported by a shaft 15 at an intermediate portion thereof, and is supported by a spring 16 provided on the shaft 15.
is urged in the direction of contacting the stopper portion 13A. With the regulating portion 14B in contact with the stopper portion 13A, the closing portion 14A extends substantially horizontally into the outlet 3 to close the outlet 3. Further, a shaft 17 is provided at the other end of the regulating portion 14B.
The locking plate 18 is rotatably supported via the shaft 17.
The locking plate 18 and the regulating portion 14B are biased by a spring 19 provided at the portion so that the locking plate 18 and the regulating portion 14B are approximately perpendicular to each other.

Reference numeral 20 denotes a locking member whose lower end is rotatably supported by a shaft, and whose upper end is provided with a locking portion 20A that can be freely engaged and detached from the locking portion 18A of the locking plate 18. The side surface is urged in a direction to bring the side surface into contact with the support member 10.

Reference numeral 23 denotes a control cam that is provided to rotate with the rotation of the drive shaft 6. As shown in FIGS. The control switch 24 is operated at a position corresponding to 11A to stop the drive motor 4.

Next, the operation of the above configuration will be explained. FIGS. 1 and 2 show the product delivery standby state, and the product A is in each gap 9 of the spiral member 8 and the delivery plate 1.
It is stored on 1. Further, the closing portion 14A of the regulating member 14 is pressed against the side surface of the product A on the delivery plate 11, and the regulating portion 14B is rotated upward against the elasticity of the spring 16.

When the product delivery command is sent to the drive motor 4, the drive motor 4 rotates the drive shaft 6 in the direction of arrow B shown in FIG. Therefore, the products A stored in each gap 9 are gradually transferred downward. on the other hand,
The support member 10 is rotated by the rotation of the drive shaft 6 to move the delivery plate 1
Separation starts from the lower surface 11A of 1. Further, the locking member 20 is pressed and rotated outward about the shaft 21 portion by the support member 10 against the elasticity of the spring 22 . As shown in FIG. 3, when the support member 10 separates from the lower surface 11A of the delivery plate 11, the delivery plate 1
1 is released from support by the support member 10, is rotated downward by the load of the product A, opens the delivery port 3, and sends the product A out. When this product A is dropped and sent out, the regulating member 14, which had been pressed and rotated by the product A, is moved to the shaft 15 by the elasticity of the spring 16.
The regulating portion 14B is brought into contact with the stopper portion 13A, and the closing portion 14A is extended into the outlet port 3. Further, due to the rotation of the regulating member 14, the locking portion 18A of the locking plate 18
The locking member 20 comes into contact with the locking portion 20A of the locking member 20 which has been rotated under pressure, and is positioned below the locking portion 20A by utilizing the elasticity of the spring 19, so that the locking member 20 can be engaged. Therefore, the regulating member 14 has a closing portion 14A.
In the state in which it extends into the delivery port 3, it becomes a locked state, and the delivery port 3 is closed. Therefore, when the delivery plate 11 opens the delivery port 3, the delivery port 3
Even if an attempt is made to tamper with the product A held in each gap 9 of the spiral member 8, the closing portion 14A of the regulating member 14 can prevent this.

On the other hand, at this time, the support member 10 is located on the side opposite to the outlet 3 with the drive shaft 6 interposed therebetween. When the drive shaft 6 further rotates, the tip of the support member 10 presses the hanging delivery plate 11 to return it to a horizontal state, and the lower surface of the delivery plate 11 is supported by the support member 10. As the drive shaft 6 rotates after this supported state, the locking member 20 is released from the pressure applied by the support member 10, and the elasticity of the spring 22 causes the locking portion 20A to be locked on the locking portion 18A of the locking plate 18. It rotates inward from the position where it can be connected and returns to its original position. After the locking member 20 returns to rotation, the product A stored in the lowest gap 9 of the spiral member 8 moves away from the terminal end 8A of the spiral member 8 and moves to the delivery plate 11.
be dropped on top. Therefore, due to this dropped product A, the regulating member 14 is pressed and rotated again.
The closing part 14A is brought into contact with the side surface of the product A, and the regulating part 1
4B and the locking plate 18 are in a state where they are rotated upward. When the state shown in FIGS. 1 and 2 is reached, the control cam 23 operates the control switch 24 to stop the drive motor 4 and enter a standby state.

(G) Effects of the Invention In the present invention, the delivery plate opens the delivery port by the rotation of the drive shaft and delivers the product on the delivery plate, and after the delivery plate returns to rotation, the product is transferred from the lower end of the spiral member onto the delivery plate. Since the product is sent out and the delivery port is closed by the regulating member when the delivery port is opened by the delivery plate, mischief such as unauthorized removal of the product can be reliably prevented, and Products can be sent out.
