Analysis of Assembly Line Conveyors


Assembly line conveyors complete assembly line operations through the cooperation of humans and machines. They are the most typical combination of humans and machines. Assembly line conveyors have strong flexibility and can meet the assembly needs of various products. Based on the specific assembly process of the product, flow lines and their functions are designed to flexibly cooperate with humans. Their transmission methods also include synchronous or asynchronous transmission, Manual or semi-automatic assembly can be achieved based on the selection of configurations, and different production process requirements can be met by adjusting the conveying speed of the line body, which can be controlled through normal continuous operation, rhythm operation, and variable speed operation. The line body can be selected in forms such as curves, slopes, or straight lines according to local conditions.

Assembly conveyor is a special form of product oriented layout, which refers to a continuous production line connected by some material handling equipment. Assembly conveyor is a very important technology, and it can be said that any final product with multiple components and mass production is to some extent produced using assembly conveyor. Therefore, the layout of the assembly conveyor is influenced by various factors such as assembly equipment, products, personnel, logistics transportation, and production methods.

Usually, it is assumed that the timing of the assembly conveyor is constant, and the processing time of all workstations is basically the same. There are significant differences in assembly types, mainly reflected in:

1. Assembly variety (single or multiple products);

2. Form of rhythm control (mobile, human);

3.The type of production line layout (U type, straight type, branch type)

4. Assembly line conveyor handling equipment (belt or conveyor, trolley)

5.Characteristics of assembly line workstations (workers can sit, stand, follow the assembly conveyor line, or move with the assembly conveyor line, etc.) 5

6. The length of the assembly conveyor conveyor conveyor line (several or many workers).

The dynamic model of the assembly line conveyor system is the foundation of the dynamic design of the assembly conveyor. At present, there are two main methods for dynamic simulation of assembly line conveyors: one is to consider the assembly conveyor system as a whole and establish a continuous belt conveyor model; the other is to use the discrete belt block method to establish a discrete model of the assembly conveyor for solution. Due to the complex electromechanical system of the assembly conveyor system, its continuous model is almost impossible to obtain analytical solutions, and generally only the simplified system equations can be numerically solved. So in practical engineering applications, discrete band blocks are often used

Dynamic simulation of the assembly conveyor system can be carried out using the method. Due to the structural complexity of the assembly conveyor system, it is almost impossible to establish dynamic equations based on the part level, so it is necessary to simplify the assembly conveyor system. Only considering the longitudinal vibration of the conveyor belt, the conveyor belt and materials are evenly distributed along the centerline of the conveyor belt; The mass of the rotating part of the roller is evenly distributed along the centerline of the conveyor belt; The material characteristics of the conveyor belt are linear: there is no slipping between the conveyor belt and the drum, and there is no consideration for the elasticity of the assembly conveyor frame and the roller (drum) group.

If real-time dynamic monitoring of the assembly conveyor system is required, tension sensors can be installed at the head, middle, and tail of the assembly conveyor model, which can not only display the time-varying tension curve of the conveyor belt, but also output and save tension data in the form of a file.
