Movement path drawing device

A movement path drawing device for drawing movement paths of movable parts of a plurality of systems of a machine, the systems being controlled on the basis of control programs for respectively controlling the systems, the movement path drawing device comprising:

• a memory that stores execution times for respective blocks of the control programs;
• and
• a processor configured to:
• create movement command data by analyzing the control programs;
• create the movement paths of the movable parts on the basis of the movement command data;
• perform drawing execution control for drawing further movement paths indicating a positional relationship between the movable parts of the plurality of systems at a predetermined time on the basis of the execution times of the respective blocks of the control programs and the movement paths of the movable parts;
• and
• execute drawing processing for drawing the movable parts of the plurality of systems in accordance with the drawing execution control,
• wherein the processor is configured to perform the drawing execution control relating to execution of a step of temporarily stopping drawing at a time of an execution changeover between blocks of the control programs, and
• wherein the processor is configured to
• create divided paths to be used during the execution of the step of temporarily stopping drawing on the basis of the movement paths of the movable parts, and
• perform the drawing execution control for drawing the further movement paths indicating the positional relationship between the movable parts of the plurality of systems at the predetermined time on the basis of the execution times of the respective blocks of the control programs and the created divided paths.
