Eccentric rotating transition machine

Abstract

This utility model proposes an eccentric rotary transfer machine, relating to the field of skid conveying technology, used in conjunction with a roller bed. It includes: a transfer track, a horizontal transfer mechanism, a rotary transfer mechanism, and a limiting mechanism. The transfer track is horizontally parallel, the horizontal transfer mechanism is bolted to the top of the transfer track, the rotary transfer mechanism is bolted to the inner side of the horizontal transfer mechanism, and the roller bed is bolted to the rotary transfer mechanism. The limiting mechanism controls the horizontal transfer mechanism and the rotary transfer mechanism to cooperate in rotating and adjusting the position of the roller bed. The rotary track has a small arc-shaped track and a large arc-shaped track, ensuring that the rotation center of the conveying roller bed does not coincide with the geometric center of the roller bed.

Description

Technical Field

[0001] This utility model relates to the field of skid conveying technology, specifically to an eccentric rotary transfer machine. Background Technology

[0002] Currently, roller conveyors are widely used in automobile production. They are used to load heavy workpieces. Because roller conveyor lines have low foundation requirements, are easy to install and modify, and are convenient to maintain, and operate intermittently with low energy consumption, they are widely used in automobile production lines. When it is necessary to change the direction of material transport, a combination of a central rotary table and roller conveyors is usually used. The rotation center of the roller conveyor is always located at the center of the central rotary table, and the outer edges of the roller conveyor are equidistant from the rotation center, occupying the same amount of space. This makes them unusable in some situations where space is limited.

[0003] As a transport carrier for vehicle body assemblies, skids are currently the most common type of rotary transfer machine used in the industry, all of which are center-rotating. When space is limited, the rotation process of a conventional center-rotating transfer machine can interfere with surrounding equipment or walls, making it impossible to meet the process layout requirements. Alternatively, additional conveying equipment may be needed to achieve the corresponding function by changing the path, which is costly.

[0004] The existing utility model patent with publication number CN210883957U proposes a central rotating device for a roller conveyor line in automobile production. The roller mounting bracket is made of bent steel plate, which reduces weight, facilitates processing, and reduces energy consumption during equipment operation. The traveling wheel assembly is installed in the bending space of the roller mounting bracket, making the traveling wheel assembly less prone to damage. The mounting hole of the traveling wheel rotation shaft is an open U-shaped hole, which facilitates the installation and maintenance of the traveling wheel and expansion sleeve. However, this utility model adopts central rotation, which requires a large amount of space and has the problem of being unusable in space-constrained areas.

[0005] To solve the above problems, it is urgent to develop an eccentric rotary transfer machine. Utility Model Content

[0044] Example 1

[0045] In this invention, the transfer drive system 3 operates, controlling the transfer drive wheel 4 to rotate via the coupling 9.
