Assembly line operation, but not fast is good, its action must be incidental value, so it is still to see whether the action is simple and clear, so the demand for the concept of economic principles of action, in simple terms, human hand movements can be divided into mobile, grip, release, front, set up, use, decomposition, there will be a psychological role of the spirit, in which strictly speaking only two kinds of action has incidental value: set up Therefore, under the condition of meeting the needs of production and manufacturing, other actions should be excluded or simplified as much as possible. The principles are as follows.

1、Movement:to make the material automatically reach the required position, greatly shorten the moving distance, greatly reduce the weight of the items to be moved, move the path around the avoidance of things that will impede the movement, so that the box inclined in order to greatly shorten the distance around the edge, and so on.

2, grip: the material in the box as neatly as possible in an orderly manner, do not clutter the pile, it is not convenient to take things can be reserved for the first grip space.

3, the front: with the same grip, the materials in the box as much as possible neat and orderly discharge, do not messy pile up and so on.

4、Organization:to replace the hand work with the tool.

5、Usage:to make the machinery fully automated.

6, mental role: the full use of machinery and equipment to replace the human factor judgment, greatly reducing the operator's eye movement.

Installation considerations of the assembly line.

The planar design of the assembly line should ensure the shortest transportation route for parts and components, easy and quick operation for manufacturing workers, convenient work for auxiliary service departments, the most effective use of the manufacturing area, and give full consideration to the interconnection between the installation of the assembly line. In order to meet the needs of these needs, in the assembly line layout should consider the form of assembly line, assembly line installation workplace arrangement method and other issues.

Assembly line installation workplace arrangement should be in line with the process route, when the process has more than two workplaces, to fully consider the same process workplace arrangement method. Generally when there are two or more than two even number of the same kind of workplace, to give full consideration to the use of double row arrangement, will be divided into two cases in the transportation route. However, when one worker is supervising several pieces of equipment, due consideration should be given to keeping the distance traveled by the worker as short as possible.
