Patent ID: 11179826

Abstract:
A shot treatment apparatus and a shot treatment method that can efficiently detect operational abnormalities and signs of operational abnormalities, and that can further take countermeasures based on the detected signs of operational abnormalities. This shot treatment apparatus is provided with a storage portion, a nozzle, a transport path, a compressed-air supply portion, a negative pressure gauge, an abnormality detection unit, an abnormality response unit, and a control unit. Shot material is transported to the nozzle by negative pressure generated in the interior of the nozzle. The negative pressure gauge is disposed on the transport path by which the shot material is transported. The abnormality detection unit detects “operational abnormalities” and “signs of operational abnormalities” based on detection results from the negative pressure gauge. The abnormality response unit operates based on the detection results from the abnormality detection unit. The control unit controls the operations of this abnormality response unit.
