BACKGROUND OF THE INVENTION AND PRIOR ART AND ITS PROBLEMS In conventional low-mix high-volume production, it is common to connect tanks to each other with pipes. As a result, many complicated pipes are laid and the pipes are cleaned. However, problems such as elimination of contamination remained. On the other hand, recently, demand has been diversified and individualized, and each company has been further diversifying its products in order to respond to them. As a result, conventional low-mix high-volume Multi-variable production is becoming mainstream.

[0003] That is, a wide range of consumers who want more individual and functional products than conventional general-purpose products using various additives and coloring agents as well as a large number of raw materials and auxiliary materials. In order to meet the needs, the product concept has been individualized, highly functional, high-performance, and high-grade, and there is an increasing tendency to produce new brands of the same product with different specifications and functions to cultivate new demand. . In order to respond to such social trends and demands, development of a new multi-product small-quantity production and multi-product variable production system has been in progress for a long time. It is said to be the most desirable production method that satisfies needs and is efficient, and a production method similar to this is partially adopted in a limited manner.

That is, in the above-described production system, the tank is placed or loaded on an automatic transport trolley, transported to a number of stations, and the tank is transferred to each station to perform a predetermined operation, and the operation is completed. At this time, the tank is returned from the station to the automatic transport carriage and transported to another station to perform another operation sequentially. However, these transfer and return devices are conventionally mostly used for roller conveyors and chain conveyors. It was a method. However, in these roller conveyor and chain conveyor systems, it is necessary to provide a conveyor driving source at each station, and the capacity of the tank is limited by weight, and it is difficult to accurately position the tank.
