Counterbalanced Servo End Seal Carriages

摘要

A sealing machine having a movable carriage assembly which utilizes a counterbalance and two servo motors is disclosed. The counterbalance allows high throughput operation without excessive mechanical vibration. The use of two servo motors allows independent control of the horizontal movement of the movable carriage assembly and the vertical movement of the jaws. The use of two servo motors also allows adaptation to articles or packages of various dimensions. In some embodiments, an optical sensor is used to detect the position of the package to be sealed, and the movement of the movable carriage assembly and the jaw is altered based on the detected position.
