Vending machine lift and anti-theft pickup structure

Abstract

The invention relates to a vending machine lift. The lift comprises a bottom plate, side plates and belts; the two side plates are arranged at the two side ends of the bottom plate respectively, the two belts are arranged on the side walls of the two sides of a vending machine box body and provided with follower plates, the inner side of each follower plate limits and clamps the side plate at thesame side, and the follower plates can limit the side plates in the vertical direction and the front-rear direction. The installation structure, weighing structure, guiding sliding structure and balance structure of the vending machine lift are improved, and various problems in the prior art are solved; a pickup door of a vending machine can be arranged at any portion of a door body and is in linkage with an anti-theft plate, convenience is provided for manufacturers to carry out assembly and maintenance, and the lift is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of improving the anti-theft and goods-retrieving structure of a vending machine, in particular to a vending machine elevator and an anti-theft and goods-retrieving structure. Background technique [0002] A vending machine is an automatic device for selling goods. Its general structure is: it includes a box body 1, a door body 56, a warehouse 60, a pick-up door 59 and an elevator 61. There are 6 doors at the front opening of the box body. The door panel 58 on the door body is provided with a pick-up door, and the door body on the door panel side is provided with glass 57, and multi-layer warehouses are set from top to bottom in the casing, and commodities are placed in each warehouse. When in use, people first select commodities from the interactive unit on the cabinet and pay for them, then the control unit in the cabinet controls the elevator to rise to the corresponding warehouse, the warehouse pushes the...

AI Technical Summary

Problems solved by technology

[0003] The defects of the structure of the above-mentioned elevator include: 1. The structure of the existing elevator itself is complicated, and installation and maintenance are inconvenient; 2. The elevator has an infrared detection unit, but when in use, once the infrared emitting end is polluted by debris , occlusion, will lead to failure to work normally and affect the detection effect. When multiple objects fall at the same time, the existing infrared detection method cannot effectively identify; 3. There is an auxiliary limit sliding block on the outside of the elevator. It is a cuboid or cube, and its edges and corners are easy to collide with the inner wall and bottom surface of the chute it is embedded in, resulting in large frictional resistance and affecting the service life of the belt drive motor; 4. The elevator itself has a certain weight, and it is pushed to its The goods on the vending machine also have a certain weight, which will affect the service life of the belt when used for a long time, and the manufacturer can only increase the thickness of the belt or use new materials, which will inevitably increase the production cost and is not conducive to the market competition of the vending machine.

[0007] For the above-mentioned patent 2: the anti-theft function cooperates with each other through the anti-theft board bracket 1, the anti-theft board 2, the driving device, the screw rod 7, the screw rod cover 13, the connecting piece 9, the front limit switch 10, and the rear limit switch 8. It can be realized. When it works, the screw rod rotates to drive the anti-theft plate to extend, and then the front and rear limits are realized through the limit switch. From the actual use, the speed of the screw rod is relatively slow, which will cause people to wait for a long time when it moves. time, and the control accuracy is poor, it must cooperate with the front and rear limit switches to realize the front and rear limit, resulting in complex structure and many control parts
