Abstract
A conveyor system for transporting a plurality of liquid-filled containers each having an open top is set forth. The conveyor system comprises a conveyor for supporting the plurality of liquid-filled containers. The conveyor is driven by a servomotor. A programmable servomotor control system is connected to control movement of the servomotor in indexed steps in accordance with a programmed motion profile. The programmed motion profile includes a move portion and a dwell portion, the move portion being substantially non-jerk limited. The non-jerk limited motion profile may take on many different characteristics. Preferably, the non-jerk limited profile is selected from the group consisting of a non-jerk limited constant acceleration profile having cosinuous acceleration transitions at beginning and end portions thereof, a non-jerk limited ramping acceleration profile, a non-jerk limited, pure cosine acceleration profile, and a non-jerk limited hybrid ramping acceleration profile with a subtractive cosine acceleration component. A method for selecting a motion profile for use in a packaging machine is also set forth herein.
