観点から好ましくない。As a switching device for the multipoint pipeline, for example,
Japanese Patent Publication No. 35309 and Japanese Patent Publication No. Sho 50-1089 have been proposed. However, it is necessary to clean liquid dripping that occurs when the pipeline is switched, and this cleaning liquid is necessary for controlling the drive unit that drives the rocking plate. It is very difficult to switch the connection of the multipoint pipeline by centralized management by a remote device because it is likely to be scattered on the electrical wiring, the supporting mechanism of the rocking plate, various instrumentation devices and the like and cause a malfunction or malfunction. On the other hand, human manual cleaning is not preferable from the viewpoint of sanitary properties and microbial contamination of liquid processing plants for foods, chemicals and the like.

切換装置。1. One end of four pipes through which a processing liquid and a fluid for washing and sterilizing a pipe line flow are disposed concentrically on a fixed plate and at equal intervals in a circumferential direction, and are mounted by opening one end. An oscillating plate having two U-shaped connecting tubes open at both ends facing two adjacent openings of these tubes is inserted through the axial center portion of the fixed plate so as to be able to reciprocate linearly and oscillate rotationally. Attached to the tip of the swing shaft, the drive unit drives the swing shaft to linearly reciprocate and rotate the swing plate relative to the fixed plate, so that two adjacent openings in the fixed plate are mutually connected. In the automatic line switching device in the liquid processing plant that switches to be connected, the rocking plate includes a cleaning device for cleaning liquid dripping at the line connection portion, and is provided on the side of the fixed plate near the line connection portion. A cover covering the pipe connection section and the washing device, A fluid pressure cylinder and the swing actuator constituting the driving portion on the opposite side of the road connecting portion, respectively provided, automatic switching apparatus of the conduit in a liquid treatment plant, characterized in that.
