DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product transport device for a vending machine having a mechanism for pushing out and carrying out products stored in a stack.

Structure of the conventional example and its problems FIGS. 6 to 6 show a conventional product delivery device. The configuration of this conventional example will be explained below with reference to FIGS. 5 and 6.

In the figure, reference numeral 1 indicates a plurality of product storage frames arranged side by side, and in each product storage frame, a large number of products 2 are stacked and stored in two rows, front and back. Restricting parts 3 are bent and formed on both sides of the front and rear edges of each product storage frame 1 so as to face each other, and the movement of the product 2 in the front and rear directions is restricted. is a product unloading section 4 through which only the lowest stage of the products 2 can pass.
is notched. This product storage frame 1 is arranged in parallel on the upper plate part 6 of a support frame 5 fixed to the vending machine main body (not shown), and each product is stored in the upper plate part 6 of the support frame 6. A long hole-shaped guide groove 7 is formed in the front and back direction at the center of the frame 1, and a front plate part 8 connects an external connector to first and second connectors 9 and 10, which will be described later. An opening 11 is formed for opening the rear plate portion 12.
An insertion hole 13 is formed in the hole.

Reference numeral 14 designates a product carrying unit covered by a base frame 15, in which an upright part 16 formed at the front part of the base frame 16 is fixed to the front plate part 8 of the support frame 6 with screws 17, and a part at the rear part is fixed to the front plate part 8 of the support frame 6. The support frame 5 is attached to the support frame 5 by inserting the protruding hook portion 18 into the insertion hole 13.

A guide groove 19 similar to the guide groove 7 of the support frame 6 is formed on the upper surface of the base frame 15 at a position below the guide groove 7 of the support frame 6.

A cylindrical cam body 20 is arranged below the guide groove 19 and parallel to the guide groove 19, and has both ends rotatably mounted on the base frame 16. On the outer peripheral surface of the cam body 20, an endless spiral groove is formed, which is composed of a right spiral groove 21 and a left spiral groove 22 that intersects with the right spiral groove 21, and whose both ends are connected by a connecting groove. . This cam body 20 is attached to the base frame 15
It is driven and rotated by a motor 24 as a driving means via a gear interlocking mechanism 23 provided at the rear end.

Reference numeral 26 denotes a movable body, which is formed into an annular body that covers the cam body 2Q, and has a slide provided inside that is connected to the right spiral groove portion 2 of the cam body 23.
1 or the left spiral groove 22. A connecting portion 26 extending through the guide grooves 7 and 19 of the base frame 15 and the support frame 5 extends above K1-1 of this moving body 25,
A product extrusion plate 27, which is located at the lower end of the product storage frame 1 and has a lower height than the product 2 from which the product 2 is carried out, is attached to and detached from the connecting portion 26 through a fitting hole 27a. has been done.

Reference numeral 28 is a lever that connects both ends of the lever body 2o to the base frame 1.
The movable body 25 is mounted on a shaft supported by the movable body 25 so as to move in synchronization with the movable body 25.

Located below this lever 28, a normally closed reciprocating drive microswitch 29 is located at the front end as a first detection element, and a normally open one-way drive microswitch 29 is located in the center as a second detection element. A microswitch 3o is provided.

Next, the operation of the above conventional example will be explained.

The moving body 25 and the lever 28 are located at the front end of the cam body 20 before the operation is started. Therefore, the actuator of the reciprocating drive microswitch 29 is pressed and released by the lever 28, and the one-way drive microswitch 3
The actuator at 0 is not pressed and is open.

First, a case will be described in which two products 2 are carried out in one operation. In this case, connect the external connector to
connector 9 so that only the reciprocating drive microswitch 29 is activated.

Here, when the purchaser performs a predetermined operation, an unloading command signal is issued, the motor 24 is driven, and the cam body 20 is rotated. The rotation of the cam body 2o causes the movable body 26 to move rearward, and the product 2 at the last stage is pushed out from the product delivery section 4 onto the product push-out plate 27. When the movable body 26 reaches the rear end, the spiral groove of the cam body 20 starts to be formed into an endless shape. As the movable body 25 moves forward, the pushing body 27 also moves, and the product 2 at the lowest stage of the front light is carried out to the product carry-out section 4. Further, the lever 28 is also moved forward at the same time as the moving body 25 moves, and when the moving body 25 reaches the front end and completes carrying out the product 2, the lever 28 also reaches the front end like the moving body 26, The actuator of the reciprocating drive microswitch 29 is pressed to open it.

Therefore, the power supply to the motor 24 is cut off, the drive is stopped, and the rotation of the cam body 2o is stopped, so that the movable body 25 is also stopped.

In this way, each time the purchaser performs a predetermined operation, the above operation is repeated to carry out two products 2 at a time.

Next, a case will be described in which the products 2 are carried out one by one in one operation. In this case, connect the external connector to the second
connector 10 so that only the one-way drive microswitch 30 is activated.

Then, when the purchaser performs the predetermined operation, an unloading command signal is issued, and the unloading operation is performed in one direction, and each time the purchaser performs the predetermined operation, the goods are alternately picked up from the front row and the rear row.
Transport them one by one.

However, in the conventional example described above, only one-way and reciprocating driving of the movable body 26 can be performed, so the number of products 2 to be carried out in one predetermined operation by the purchaser is limited to two at most. Moreover, since 202 products are carried out by reciprocating the movable body 26, there is a drawback that it takes twice as long to carry out 2 products as it takes to carry out 1 product.

OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of the above-mentioned conventional example, and aims to allow the number of products to be carried out to be freely selected and to shorten the time for carrying out the products.

Structure of the Invention In order to achieve the above object, the height of the product pushing member and the height of the product delivery section are made variable according to the height of the number of products to be delivered. It is also possible to carry out two or more products at one time by operating the .
