Shot-blasting device, inspection method, and computer-readable storage medium recording inspection program

A shot-blasting device comprising:

• at least one impeller each of which has at least one motor and projects a blasting medium to at least one projection target object;
• a memory which stores a threshold and a determination condition for use in an inspection process, and records a determination result, and
• at least one processor,
• the at least one processor carrying out a first inspection process and a second inspection process after a device is activated and before the blasting medium is projected to the at least one projection target object,
• the first inspection process being a process in which, in a state where no blasting medium is supplied to the at least one impeller while the at least one motor is rotating, the at least one processor reads a first threshold from the memory, the at least one processor determines whether a current value supplied to each of the at least one motor of the at least one impeller is not more than the first threshold, and the at least one processor stores a result of the determination as a first inspection result in the memory,
• the second inspection process being a process in which, in a state where the at least one impeller is projecting the blasting medium, the at least one processor reads a second threshold from the memory, the at least one processor determines whether the current value supplied to each of the at least one motor of the at least one impeller is not less than the second threshold, and the at least one processor stores a result of the determination as a second inspection result in the memory,
• the at least one processor reading the first inspection result and the second inspection result from the memory,
• the at least one processor carrying out a display process for displaying, on a display, at least one of (1) the result of the determination, given by the at least one processor, of the first inspection process and the result of the determination, given by the at least one processor, of the second inspection process or (2) a determination result obtained by the at least one processor generalizing the result of the determination, given by the at least one processor, of the first inspection process and the result of the determination, given by the at least one processor, of the second inspection process,
• the first inspection process carrying out an inspection for a defect in the at least one motor or a part involved in driving of the at least one motor,
• the second inspection process carrying out an inspection as to an amount of supply of the blasting medium to the at least one impeller, and
• in a case where the current value supplied to each of the at least one motor of the at least one impeller is lower than the second threshold, the at least one processor is configured to cause an increase in the amount of supply of the blasting medium to the at least one impeller.
