Abstract
A centrifugal barrel polishing machine includes a distance measurement sensor 15. When a barrel tank 50 is located in a detection area, a controller 10 determines whether a fixed-state distance is measured by a distance measurement sensor 15, and when the fixed-state distance is not measured, the controller 10 does not permit the rotation of a turret 22.
Claims5
A centrifugal barrel polishing machine comprising:
- a turret rotationally driven around a revolution shaft extending in a horizontal direction;
- a barrel case that is rotationally driven around a rotation shaft that extends in the horizontal direction from a position eccentric from the revolution shaft in the turret;
- and
- a barrel tank housed in the barrel case;
- a fixing member that changes between a fixing form for fixing the barrel tank to the barrel case and a releasing form for releasing the fixation of the barrel tank to the barrel case;
- and
- a distance measurement unit disposed to face in a measurement direction, along a substantially horizontal direction, with respect to a detection area located on a revolution path, of the barrel tank, centered on the revolution shaft;
- and
- a controller,
- wherein the fixing member includes a to-be-measured portion whose position is displaced between the fixing form and the releasing form,
- when the fixing member changes from the fixing form to the releasing form, the to-be-measured portion is displaced from the measurement direction of the distance measurement unit to a direction intersecting the measurement direction, and
- when the barrel tank is located in the detection area, the controller determines whether a fixed-state distance indicating a horizontal distance to the to-be-measured portion is measured by the distance measurement unit, and when the fixed-state distance is not measured, the controller does not permit the turret to rotate.

A centrifugal barrel polishing machine comprising:
- a turret rotationally driven around a revolution shaft extending in a horizontal direction;
- a barrel tank including a barrel body and a barrel lid, the barrel tank being rotationally driven around a rotation shaft that extends in the horizontal direction from a position eccentric from the revolution shaft in the turret;
- and
- a fixing member that changes between a fixing form for fixing the barrel lid to the barrel body and a releasing form for releasing the fixation of the barrel lid to the barrel body;
