Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a product delivery shelf device for a vending machine.

(B) Conventional technology Conventionally, a large number of product shelves are provided on an endless chain stretched vertically, and the product shelf on the lower side is supported by a guide support rail in a state where products can be placed, and the product is lowered in the conveyance path. There is known a product carry-out shelf device for a vending machine in which support by the guide support rail is released at a predetermined position below and the product is dropped and carried out; ing.

(c) Problems to be Solved by the Invention The product shelves in this type of prior art are constructed with dimensions that allow for easy descent while engaged with the guide support rails. When supported by the guide support rail, it is more likely to take a downward position than a horizontal position.

Therefore, there is a problem in that the products placed and stored on the product shelf tend to protrude forward and fall due to vibrations when the product shelf is moved.

In addition, in order to prevent tampering with the stored products on the lowest product shelf supported by the guide support rail, if a tamper prevention plate is provided in front of the lowest product shelf, the front When the product shelf on which the protruding product is placed descends to the lowest position, the product is latched to the upper end of the tamper prevention plate, and is clamped between the product shelf and the product shelf, resulting in a locked state.

For this reason, the present invention prevents products from protruding from product shelves supported by guide support rails, and
To provide a product conveyance shelf device for a vending machine that does not cause a locked state between it and a mischief prevention plate.

(D) Means for Solving the Problems The present invention provides a large number of product shelves on an endless chain stretched vertically, and supports the product shelves on the descending side by guide support rails in a state where products can be held. descend in the general transportation aisle,
In a vending machine in which the support by the guide support rail is released at a predetermined position below and the product is dropped and carried out, the conveyance is carried out corresponding to the front of the lowest product shelf supported by the guide support rail. A tamper prevention plate is provided to cover the surface of the passage 1iij, and the product shelf is provided with a recess that opens forward at the front end, and a guide is positioned to advance into the recess of each product shelf in the vertical direction supported by the guide support rail. The member is provided on the back side of the front door so as to extend to a position above the tamper prevention plate.

(E) Effect In the present invention having such a configuration, products are placed and stored on a product shelf that descends while being supported by guide support rails in a conveyance path, and the products are moved onto the product shelf by a guide member positioned in a recessed part of the product shelf. It is prevented from protruding from the top and is guided downward so as not to be stopped by the mischief prevention plate at the bottom. The front surface of the conveyance path of the lowest product shelf supported by the guide support rail is covered with a tamper prevention plate11. Mischief to the stored products is prevented.

(F) Embodiment Each figure shows an embodiment of the present invention. 1 is a vending machine main body with a front door 2 that can be opened and closed, and a product delivery shelf device 3 is installed in the main body 1. It is set up.

The product delivery shelving unit @3 has a drive shaft 5.6 at the top and bottom of the base 4, and sprockets 7 at both left and right ends of the drive shaft 5.6.
．． There are 8. and upper and lower sprockets 7.
An endless chain 9, 10 is stretched between the 8 and 8, and is rotated by the drive of a drive motor 11 connected to the drive shaft 5.

Also, chain 9. IOr#X1 is provided with a plurality of product shelves 12 at equal intervals in the vertical direction, with one end rotatably supported by a shaft, thereby forming an endless vertical conveyor.

The product shelf 12 includes a rear shelf board 12A, which is rotatably supported by a chain 9.10, and a front shelf board 12B, which is connected to the shelf board 12A by a hinge connection, which is rotatably connected to the shelf board 12A. Guide rollers 13 are divided into two parts, and are protruded laterally and rotatably supported at both front and rear ends of the rear shelf board 12A and at both front and rear ends of the front shelf board 12+3. At the same time, a recess 14 that opens forward is provided at the front end portion, which is the tip of the front shelf board 12B, approximately in the center.

15.16 and 17.18 are provided in pairs on the lower side of the chains 9 and 1o, facing each other on both side walls 4A and 4B of the base body 4 so as to be located substantially parallel to the chains 9 and 10. The guide roller 13 on the rear side of the rear shelf board 12A is supported in contact with a guide support rail 15, and the guide roller 13 on the front side is supported in contact with a guide support rail 16. Further, the guide roller 13 on the rear side of the front shelf board 12B is supported in contact with a guide support rail 17, and the guide roller 13 on the front side is supported in contact with a guide support rail 18. As each guide roller 13 comes into contact with each guide support rail 15, 16, 17, and 18, the product shelf 12 is supported approximately horizontally so that products can be stored in a position, and the products are placed between the side walls 4A and 4B. It is possible to descend within the conveyance passage 19 that is formed.

In addition, the product 1112 includes each guide support rail 15. ■6.1
7. When the support is released at the lower end of the 18 fl, it rotates downward and becomes a tilted state, and the product A that was placed a is sent out onto the delivery chute 20, and the product A is the product installed in the front door 2. It is designed to be delivered to the outlet 21.

Reference numeral 22 denotes a rack installed between both side walls 4A and 48 so as to cover the front surface of the conveyance path 19 and to correspond to the front of the lowest product shelf 12 supported by each guide support rail 15, 16, 17, 18. This is a prevention plate, and prevents the product A placed and stored on the lowest product shelf 12 from being tampered with by a hand or the like inserted through the product removal port 21.

Reference numeral 23 denotes a guide member provided on the back side of the front door 2 to protrude rearward and extend vertically.When the front door 2 is closed to the main body 1, each guide support rail 15, 16,
17 and 18 to prevent the product A on each product 41112 from protruding forward, and to place the lower end above the upper end of the mischief prevention plate 22. It is extended to the position.

Therefore, since the product A on the product shelf 12 supported by each guide support rail 15, 16, 17° 18 is prevented from protruding forward by the guide member 23, the product shelf 12 moves to the lowest position. Even if the user wants to do so, he or she can move to the lowest position without being stopped by the mischief prevention plate 22.

Moreover, since the front side of the conveyance path 19 is opened by opening the front door 2, the guide member 23 does not interfere with the loading of products onto each product shelf 12.

(g) Effects of the Invention The present invention places and stores products on a product shelf that is supported by guide support rails and descends in a conveyance path, and the products are moved from the product shelf by a guide member positioned in a recessed part of the product shelf. The product shelf at the lowest level is prevented from protruding and is guided downward so as not to be stopped by the tamper prevention plate at the bottom, and is supported by the guide support rail. , Since this is to prevent mischief to the products stored on the shelf, the products stored on the product shelf,
It is possible to prevent products from protruding forward and falling due to vibrations when the product shelves are moved, and to be provided with a tamper prevention plate to prevent mischief to the stored products on the product shelves supported by the guide support rails. In addition, it is possible to prevent the occurrence of a erroneous condition caused by the products on the product shelf being caught on the upper end of the mischief prevention plate.
