DEVICE FOR FEEDING LIQUID TO INKJET HEAD AND DEVICE FOR WIPING INKJET HEAD

摘要

A device for feeding liquid to inkjet heads. The device is configured, without causing liquid feeding pipe lines to be complex, so that gas does not remain in the pipe lines when a liquid material is fed to the inkjet heads, and is devised so that the pressure of the liquid material fed to each inkjet head is uniform. Liquid material feeding pipe lines (3) individually communicating with inkjet heads (4) are connected to a common liquid feeding pipe line (2) communicating with a single ink tank (1) for containing one kind of liquid material. Gas flow pipe lines (19) are connected to a bypass pipe line (18a) (common gas flow pipe line (18) openable and closable against the air, and the gas flow pipe lines (19) individually communicate with connection sections between the common liquid feeding pipe line (2) and the liquid feeding pipe lines (3) or with the inkjet heads (4) or with both the connection sections and the inkjet heads (4).
