<p><P>PROBLEM TO BE SOLVED: To shorten a cycle time in an application accompanied with synchronization control. <P>SOLUTION: A conveyer 1 for transporting a box and a conveyer 2 for transporting a bottle are respectively driven along a follow-up target axis and a follow-up axis. The follow-up axis is accelerated from a synchronization start position (point of time a), and when the follow-up axis velocity catches up with the conveyer 1 (point of time b), the follow-up axis performs the constant velocity operation. An advanced operation, performed by an asynchronous axis (moving the bottle closer to the box), is started before synchronization completes (point of time e), and is completed when synchronization completes (point of time b), then immediately an operation by a synchronous axis (follow-up target axis or follow-up axis) is started (insertion operation). The point of time e is determined by processing of the numerical controller, as a point of time T when the time required for the follow-up axis in the current status to reach the synchronization completion status becomes the same as the time required for the advanced operation (preliminarily set). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
