Abstract
The present invention provides a packaging system that includes a beak-shaped hopper, a pair of opening and closing bars, and a sensor for sensing a limitless opening and closing movement of the opening and closing bars. The beak-shaped hopper and the pair of opening and closing bars are operable to move in unison back and forth along a main travel path. The main travel path leads to a rotary vacuum packaging device having a pressure resistant chamber. The beak-shaped hopper is dimensioned to convey packaging bags into the pressure resistant chamber. The opening and closing bars are dimensioned to detect a bag on the hopper by opening towards both sides immediately after a bag has been conveyed into the pressure resistant chamber. A pushing bar is dimensioned to convey an item to be packaged into the bag when the bag is detected on the hopper by the opening and closing bars. The opening and closing bars contact a sensor for detecting movement of the opening and closing bars when a bag is not on the hopper.
