Patent ID: 8499532

Claim:
A system for sealing a packing container, comprising: a conveyor that delivers a container to a sealing station; a sealer at the sealing station that seals the container closed as the container travels through the sealing station; a detector that detects a stalled container in the sealing station, where the detector includes one or more sensors; a sealer lift mechanism that raises the sealer upon detection of a stalled container in the sealing station to relieve the stalled condition of the container so that the container travels through the sealing station and is sealed by the sealer, where the sealer is movable between a lower height position and an upper height position; and a controller connected to the detector and the sealer lift mechanism to control the sealer lift mechanism to raise the sealer based on a signal from the detector that indicates a stalled container in the sealing station; and the controller is operably to control the sealer lift mechanism to move the sealer toward the upper height position when the sealer is not at the upper height position.
