摘要:
A system for maintaining a desired sealing force is provided, which incorporates a closed loop control system. The system includes a platen (18), which has a surface for making contact with one or more items to be sealed, a motor (14) for producing a linear movement, a linkage (20) coupled to the platen (18) and the motor (14) for transferring the linear movement produced by the motor (14) to the platen (18), and a transducer (22) coupled between the linkage (20) and the platen (18) for measuring the force applied to the platen (18) via the linkage (20) through the linear movement of the motor (14) and producing a signal representative of the force measured. A motor controller (12) produces a motor control signal, which is supplied to the motor (14) for controlling the same. The motor control signal is used to control the linear movement produced by the motor (14). The motor controller (12) further receives the feedback signal from the transducer (22), and correspondingly adjusts the value of the control signal used to control the magnitude of the linear movement.
