INK JET PRINTING DEVICE FOR STRAW TO CONTAIN BIOLOGICAL FLUID

摘要

PURPOSE: To improve straw loading, unit pickup and longitudinal feed capacity by perfectly integrating advance straws with a high speed roller group by the viewpoint of the unit pickup or simple adhesion of straws fed in successively through a distribution passage. CONSTITUTION: An ink jet printing device is constituted of the means 50 combined with an ink jet printing machine 10 and controlled by an automaton 40 and introducing straws, a unit pickup member 60 and a conveyor 70 passing taken-up straws through a printing head 11 to feed them and delivering the fed straws. In this constitution, pref. arranged negative pressure is set and straws are taken up one by one by the output of a flow passage on one side and straws are fixed on the other hand by the adhesion to a series of feed roller groups.
