CONTINUOUS BLASTING DEVICE OF TROUGH TYPE AND CONTINUOUS BLASTING METHOD OF TROUGH TYPE

摘要

PROBLEM TO BE SOLVED: To provide a method for continuous blasting and an improved device therefor capable of automatically grinding/polishing/cleaning the peripheral surface of a workpiece uniformly and performing a grinding/polishing/cleaning process of a number of workpieces continuously.;SOLUTION: A belt 13 is set over around five rollers 11a-11e, and the section where the belt is stretched between the rollers 11a and 11b is depressed by a side disc 12 to form a trough (recess) 14. The belt 13 moves round in the direction of Arrows g, f, k, and the workpiece fed in the direction of Arrow g falls into the trough 14 and rolls as shown by Arrow i. From a projector 6, grinding/polishing/cleaning material is projected (Arrow b) to the workpiece 5 which is rolling, and the whole outer peripheral surface is ground/polished/cleaned uniformly. A carryout spoon 17 is attached to the belt 13 and moves round in association with the belt moving round. Advancing into the trough, as shown in Fig. (B), the spoon 17 scoops the workpiece 5 up as shown by Arrow j, and carries it out as shown by Arrow k.;COPYRIGHT: (C)2010,JPO&INPIT
