Can be connected. After the supply of the liquid is completed, the flexible 27, 28
Then, the receiving port 16 and the discharging port 17 are separated from the supply port 9 and the liquid receiving port 12, respectively, and may be rotated with respect to a pipe to be connected next. The rotation direction of the connecting pipes 6 and 7 may be horizontal, but it is necessary to provide a sufficient margin for the wiring for operating the cylinders 29 and 30.
In FIG. 7, connecting pipes 6 and 7 are rotary joints 13.
Although FIG. 6 shows the case where the connecting pipes are rotatable, the same structure can be applied even when the connecting pipes 6 and 7 are separated and rotatable as shown in FIG. If the receiving port 16 and the discharge port 17 of the connecting pipe 6 and the connecting pipe 7 are made expandable and contractible, it is not necessary to move the supply pipe 4 and the liquid receiving pipe 5 up and down. The operation and stop of the cylinders 26, the cylinders 29, 30 and the like shown in the second and third embodiments are managed by a control device together with the entire operation mechanism.

In the above description of each embodiment, the number of supply pipes 4 and liquid receiving pipes 5 is eight, but the number can be changed according to the type of liquid used. The number of the supply pipes 4 and the liquid receiving pipes 5 does not need to be the same in the vertical direction.
