Selling commodity claiming mechanical hand

Abstract

The invention discloses a selling commodity claiming mechanical hand. A motor is in driving connection with a nut block. The nut block is provided with a pair of rollers and a door opener. The rollerslift a suction cup through a winding rope. The rollers and the rope are arranged in a clutch mode. The nut block is integrally provided with the door opener and the rollers and suction cup lifted through the winding rope, so that the mechanical hand can have the functions of opening and closing a door and the function of grabbing, and the commodity selling claiming process can be achieved just through one set of the structure. The motion type door opening and closing process has the advantages that the stability is good, the opening and closing degree of cabinet doors is adjustable, the replacement and maintenance cost is low, the adjusting process difficulty is low, meanwhile, the three-dimensional movable grabbing mechanism replaces the motor to drive a commodity pushing mechanism to push out commodity bar structures, the process of grabbing commodities by imitating human hands is achieved, multiple motors do not need to be arranged, commodities cannot cause friction with a bar channel, and the commodities are protected against injuries so that the commodity integrity can be ensured.

Description

technical field [0001] The invention belongs to the field of vending equipment, and in particular relates to a manipulator for automatically taking out commodities from a vending machine. Background technique [0002] Self-service vending equipment is mainly used in office buildings, stations, commercial centers and other places with a large flow of people to provide self-service sales of goods, which not only provides more convenient services for people to buy goods, but also reduces the labor intensity of personnel and saves The cost of sales also brings more profits to merchants. [0003] At present, when the self-service vending machines used in the market need to obtain the commodities stored in the machine, the commodities must be taken out by opening the door and grabbing. There are two common methods for the existing picking parts: one is to configure two sets of power control mechanisms to separately control the opening and closing of the freezer door and to absorb...

AI Technical Summary

Problems solved by technology

There are two common methods for the existing picking parts: one is to configure two sets of power control mechanisms to separately control the opening and closing of the freezer door and to absorb and grab the goods, but there are three disadvantages in this control method: 1. Two sets Power control, the equipment cost is relatively high; 2. Two sets of power drive require two sets of control motors, which takes up a lot of space; 3. The programming of the two sets of power control is relatively complicated

However, this control method has the following problems: when the equipment opens the freezer door, the Z-axis needs to move downwards, and at the same time drives the transmission rope and the suction cup mechanism to move downward. At this time, the position of the suction cup mechanism needs to be moved to the lower part of the freezer door. Interfering with the freezer, it is necessary to reserve space for the suction cup mechanism, which increases the overall size of the equipment and takes up a lot of space
