Title:
PALLET LOADING DEVICE CONTROL METHOD
Document Type and Number:
Japanese Patent JPH0543053
Kind Code:
A
Abstract:

PURPOSE: To provide a correct moving/stop position with the elongation of an endless belt taken into account by subtracting inertial travel rotating speed for correction to control the rotating speed of motors, thereby preventing overrun caused by inertial force to allow a load holder to be stopped correctly into a control position, and computing the moving control motor rotating speed required to move the necessary moving distance using the control reference value.

CONSTITUTION: Prior to the start of work, an article holder is moved to store the inertial travel rotating speed from the output of a stop signal to the complete stop of the article holder, and the inertial travel rotating speed is subtracted for correction from the moving control rotating speed computed at an arithmetic unit by the required moving distance to control the rotating speed of motors 1-3. Prior to the start of work, the article holder is moved also by the specified distance, and the rotating speed during that time is counted to compute the control reference value. Using this control reference value, the moving control rotating speed of the motors 1-3 is computed from the required moving distance for determination. As a result, the load holder can be always stopped correctly in a control predetermined position in a pallet loading device.
