Shot processing apparatus

A shot processing apparatus, comprising:

• a projection machine configured to project projection media onto a workpiece;
• a plurality of hanger transport devices, each of which, in a hanging state of a member on which a workpiece is set or a hanging state of a workpiece, is movable along a guide path inside the shot processing apparatus, is stoppable, and is configured to provide self-specifying identification information;
• and
• a control unit configured to control operation of the hanger transport devices by outputting, to each of the plurality of hanger transport devices, a control signal that is appropriate to each of the hanger transport devices based on the identification information provided from each of the individual hanger transport devices and based on information related to each of the individual hanger transport devices, the information being stored in advance in association with the identification information,
• wherein:
• the hanger transport devices are movable along the guide path while in a hanging state of a work set jig including a frame body for accommodating a workpiece;
• the guide path includes a curved path that is curved in apparatus plan view;
• the shot processing apparatus further comprises a rail-shaped guide section that is separate from the guide path and that is provided along a part of a transport path along which a workpiece is transported by movement of the hanger transport devices;
• the work set jig includes a guided section that is guided by the guide section;
• the rail-shaped guide section includes a left and right pair of stopping area guide sections that have an entrance corresponding to a terminal end side of the curved path in apparatus plan view and the stopping area guide sections are disposed over a range including a stopping position of the work set jig;
• and
• the control unit is configured to set a movement velocity of the hanger transport devices, at a timing at which the hanger transport devices have been detected by a detection member as passing in a vicinity of a placement position of the detection member, the detection member being arranged in a vicinity of a start end side of the curved path in apparatus plan view, to a movement velocity that enables the guided section to enter between the left and right pair of stopping area guide sections even in a case in which the work set jig sways under centrifugal force.
