The
Assembly Line operation is either fast or good. Its action must be of added value, so it depends on whether its action is simple and concise. Therefore, the concept of action economy principle is required. In short, the action of human hand can be divided into movement, grip, release, front, assembly, use and decomposition. There is also a psychological mental function, in which only two actions are strictly attached Added value: set up and use, so other actions shall be eliminated or simplified as far as possible under the condition that production requirements can be met. The principles are as follows:
1. Moving: make the material automatically reach the desired position, shorten the moving distance, reduce the weight of the items to be moved, avoid things around the moving path that will hinder the movement, make the material box oblique to shorten the distance around the edge, etc.
2. Gripping: the materials in the material box shall be arranged as orderly as possible, and the space for gripping shall be reserved for the things that are not convenient to take.
3. Front end: as with holding, the materials in the material box can be neatly discharged, and do not pile up disorderly.
4. Assembly: replace manual operation with fixture and tool.
5. Use: make the machine fully automatic, etc.
6. Mental function: use machinery to replace human judgment, reduce the operator's eye movement, etc.
Precautions for assembly line installation:
The graphic design of the assembly line shall ensure the shortest transportation route of the parts, convenient operation of the production workers, convenient work of the auxiliary service department, the most effective use of the production area, and consider the connection between the assembly line and installation. In order to meet these requirements, we should consider the form of the assembly line and the arrangement method of the assembly site.
When the assembly line is installed, the arrangement of working places shall conform to the process route. When there are more than two working places in the process, the arrangement method of working places in the same process shall be considered. Generally, when there are two or more even working places of the same kind, double row arrangement shall be considered, and they shall be listed in two cases of transportation route. However, when one worker is in charge of multiple devices, it is necessary to consider the shortest distance for workers to move.
