Abstract:
1. A control device of a work positioning apparatus for controlling the work positioning apparatus including a stage for fixing a work, and an inclination shaft, a rotating shaft, and a vertical shaft for securing the fixed work in a predetermined position in a three-dimensional space, comprising: operating limit line storage means for storing position coordinates of an operating limit line that is preset in front of a predetermined obstacle with respect to the work positioning apparatus or the work fixed to the work positioning apparatus; speed reduction zone storage means for storing a width of a speed reduction zone ranging from a reduction start position preset in front of the operating limit line to the operating limit line; check point storage means for storing position coordinates of one or more check points set in the work positioning apparatus or the work fixed to the work positioning apparatus; check point updating means for determining position coordinates of the one or more check points moved in accordance with an operation of the work positioning apparatus by calculation to update position coordinates stored in the check point storage means; in-speed-reduction-zone determining means for determining whether any one of the check points enters the speed reduction zone in accordance with the updated position coordinates of the check points; and work positioning apparatus control means for instructing a work positioning apparatus motor for driving the work positioning apparatus to reduce a speed if any one of the check points is determined to enter the speed reduction zone.
