Production line is in a certain line on the continuous transport of goods handling machinery, also known as the transmission line or conveyor. According to the delivery series of products can be roughly divided into: belt assembly line, plate chain line, multiple chain line, plug-in line, net belt line, suspension line and drum assembly line these seven kinds of assembly line. It generally includes traction, bearing member, driving device, tensioning device, reversing device and supporting parts, etc. Pipeline conveying capacity, long distance, but also in the conveying process to complete a number of process operations, so the application benefits are very extensive. With the use of assembly line from product development and design, production and manufacturing to sales of the whole process should be standardized, scientific, institutionalized; The introduction of assembly line, through the change of production process, promote the rapid flow operation, not only improve the production efficiency, but also reduce the cost of operation, improve the efficiency of enterprise management! A form of production organization in which products are processed and produced sequentially through various workplaces continuously. It is the further development of the object specialized organization form, is a kind of production organization form with fine division of labor and high production efficiency. Each process has a specific person to complete, step by step processing. Each person does a specific job. The advantage is that it's faster to produce, because everyone only has to do one thing and they're very familiar with what they're doing The main production mode of assembly line is to make the production process of field frequency better meet the requirements of continuity, balance, proportion and balance. Productivity is high, can provide the product of market demand in a timely manner. The adoption of a dedicated professional production, assembly line equipment and process equipment, as well as the mechanized transport device, so can improve labor productivity, shortening production cycle, reduce the workload, wip footprint and transportation to accelerate the capital turnover, reduce the production cost, also can JHF production management work, promote enterprise production technology preparation and production services.
