Abstract: Automation degree is not high in some enterprise，product transportation and weighing is basically artificially operation.This kind of method by using artificial transportation and measurement need a lot of manpower and material resources，labor intensity of worker is very big，production efficiency is low and not suitable for modern production requirements.This paper puts forward a production line （24 machines position on the production units）carries on the product transportation by chain conveyor closed rail ground transportation，and products in the transport process carries on the automatic metering method.So，consider the production requirement of process and the improvement of the environment and production cost can afford.Save labor intensity，and counting，make for modern computing accurate mass production.
