Conveying unit and reconfigurable and self-adaptive production line consisting of same

Abstract

The invention discloses a conveying unit and a reconfigurable and self-adaptive production line consisting of the same. The conveying unit comprises a frame body, wherein an electric control layer and a conveying layer are arranged on the frame body; and an operation layer and an equipment layer also can be arranged as required. The production line is formed by combining conveying units, and can be formed to different forms according to different demands. The conveying unit has the characteristic of modular design, is short in design time, is short in time of installing, debugging, disassembling and reassembly for a new production line, and has the features of low cost and high adaptability; and once the production line is formed, the unified management can be performed through a master controller, so that the working modes are flexible and varied, and the automation control degree is high.

Description

technical field [0001] The invention relates to the technical field of production lines, in particular to a transfer unit and a reconfigurable and self-adaptive line composed of it. Background technique [0002] In batch industrial manufacturing, production lines are widely used to adapt to standardized production and improve production efficiency, especially suitable for large-volume production of the same model. After long-term development, the topological structure of the existing assembly line can be roughly divided into five forms, namely: 1. One-word line; 2. One-word comb combination line; 3. One-word string and combination line; 4. Ring line; 5. Ring comb combination line. [0003] 1. One word line [0004] The in-line line is the earliest and most commonly used assembly line. The materials to be produced and processed are passed along the line in one direction, and are passed from the starting point to the end point after being processed by each station. One-word...

AI Technical Summary

Problems solved by technology

However, in actual production practice, due to changes in product design and production process, the continuous introduction of new products, and the continuous discovery of problems in production, the transmission path and number of operating stations of the original solidified production line often cannot meet these constantly emerging problems. New needs, and the transmission path requirements in the production of different products are often quite different

These complicated changes make the production factory either choose to still use the existing wire body, which brings about the problem of reducing production efficiency

If you choose to re-purchase new line bodies, the risk is the contradiction between increased investment in fixed assets and uncertain market demand

[0019] 2. The solidified operation sequence makes it difficult to adapt to changing product requirements

For example, a comb-shaped combination line, a certain operation station is set at the shared line position during the design of the line body. Due to the change of the production process of one of the products, it needs to be set at the position of the comb line, while the production process of other products It still needs to be set at the position of the original shared line. In this case, the existing line body can only manually transfer the equipment at this station when switching products. If the equipment installation is complicated, it needs to be re-adjusted every time, which greatly Affected production tangent efficiency

What's more complicated is that if two or more products are required to be produced online at the same time, the existing line arrangement basically cannot meet the requirements.

[0021] 3. The degree of intelligence is poor, and it is difficult to adjust in time when there is a problem, which may easily lead to transmission blockage

Once this happens, it will directly reduce the equipment utilization rate and affect the production efficiency.

[0023] 4. It is not suitable for simultaneous online production of multiple varieties and small batches

For the existing assembly line topology, the one-word comb combination line and the ring comb combination line can theoretically support simultaneous online production of multiple varieties, but once the line body is designed and assembled, it can support the maximum number of simultaneous online production varieties That is, it is limited, and once the operating equipment at each station is in place, assembled and debugged, it is difficult to change its position on the transmission path and work procedures

However, in actual demand, multiple varieties are produced online at the same time, and the on-line time, production quantity, production cycle, transmission path, operation process, and off-line time of different varieties are different. If the topology of the existing line is still used, the complexity of these problems It will make on-site management extremely complicated, so it is almost impossible to solve it completely

[0025] 5. The existing assembly line topology does not adopt a modular structure, which requires non-standard design for different production sites and transmission paths, and it is difficult for users to adjust after installation

This kind of non-standard design, regardless of using any of the above topological structures, the cycle of design, processing, on-site installation and commissioning is very long and the cost is high; and, once the installation is completed, the user needs to make adjustments, such as increasing from 10 stations to 15 stations, or changing from a circular line to a circular comb combination line to meet the needs of emerging product production processes, for users who are only users and not line designers, it becomes almost impossible to complete the task by themselves

Even if the transformation is carried out by the line body designer, it will take a long time and the cost is high, and it cannot meet the increasing rapid production requirements at all.
