Abstract
PURPOSE: To provide an automatic marking device for marking of tubing for special application, to which inscription and painting are not applicable, by employing sand blast method in which a work is able to be marked without receiving damage on the surface.
CONSTITUTION: A tubing 7 to be marked is held by a chuck 5, fed into a container 32, rotated and advanced by step by step as prescribed. A control circuit 6 is provided in advance with a prescribed input signal for issuing a command to a motor 51 for step-by-step rotation and also a command to an electromagnetic valve 23 for jetting of compressed air. Fine particles 6 are absorbed into a pressurized pipe 11 and strongly jetted out of a nozzle 13 onto the surface of a pipe 7 and then marking is made on the pipe surface. The pipe 7 is to become provided with prescribed mark one after another by aforementioned step-by-step advancing and rotation.
