A mobile robot for automatic loading and unloading of goods

Abstract

The invention belongs to the field of cargo handling equipment and particularly discloses a mobile robot capable of achieving automatic cargo handling. The mobile robot comprises a mobile platform, a grabbing mechanism, a conveying mechanism, a pallet exchanging mechanism and a film winding mechanism, wherein the grabbing mechanism comprises a front manipulator and a rear manipulator, the conveying mechanism is arranged between the front manipulator and the rear manipulator, and the pallet exchanging mechanism comprises a rotating plate module; the film winding mechanism comprises a film drawing module, a film clamping module and a film cutting module, the film drawing module, the film clamping module and the film cutting module are installed on the mobile platform, the film drawing module carries out up-and-down motion relative to the mobile platform in the film winding process, the film clamping module is a split film clamping mechanism, the film clamping module is fixedly connected with the rotating table module and rotates along with the rotating table module in the film winding process, and the film clamping module is separated from the rotating table module after the film is wound; the film cutting module is used for cutting off the film. The mobile robot can effectively solve the problem that an existing cargo handing robot is difficultly applied to narrow spaces, and has the advantages of being small in overall size, convenient to operate, high in applicability and the like.

Description

technical field [0001] The invention belongs to the field of cargo handling equipment, and more specifically relates to a mobile robot for automatically loading and unloading cargo. Background technique [0002] At present, the loading and unloading work of containers or vans is basically done by porters. In order to improve the efficiency of loading and unloading, various types of palletizing robots have appeared on the market, and most of the existing palletizing robots are limited by the space of containers (carriages). Due to the restrictions, it is impossible to complete the loading and unloading of the goods in the container (compartment). The pallet exchange mechanism and the film winding mechanism are important actuators on the loading and unloading robot. The overall structure and size of the above two mechanisms directly affect the overall volume of the loading and unloading robot, which is an important factor that determines whether it can be applied in a narrow s...

AI Technical Summary

Problems solved by technology

[0003] The pallet exchange mechanism in the existing loading and unloading robots generally adopts the form of circular assembly line and vertical assembly line, and the form of circular assembly line has four stations, which occupies space in the length and width directions of the equipment. When the forklift places empty pallets, it needs to be placed In the lower right corner, the pallet full of goods needs to be removed in the lower left corner. During this process, the forklift needs to be translated horizontally, which makes the operation more difficult; there are three vertical stations in the vertical assembly line, which increases the length of the forklift. After the empty pallet is finished, it is necessary to wait for the wrapping of the full pallet to be completed and move from the second station to the third station, which reduces the working efficiency of the forklift. The exchange mechanism also needs a side mechanical arm and its supporting guide rails and other mechanisms , increasing the complexity of the device

[0004] Most of the winding mechanisms in the existing loading and unloading robots are independent products. They work independently in the factory or cooperate with other equipment. There is no size limit for the working space and the structure of the turntable. When working inside the container or when the equipment is integrated, there are the following: Problem: The structural form of the clamping module and the turntable module is fixed, resulting in a large radial size of the turntable, which is easy to interfere with other equipment, which is not conducive to equipment integration; in addition to the mechanical connection between the clamping module and the turntable module, there is also an electrical connection. Increased electrical complexity of the carousel module
