ABSTRACT:
An automatic grocery bag opener automatically opens plastic and polyethylene bags with forced air in produce departments and at checkout counters of grocery stores. Bags are held in position from any of several different types of hangers on the front of the enclosure. The outside bag is forced and held open by the forced airstream from the air supply. The bag can then be filled with the grocery items. Once the bag is filled, it is removed from the hangers and the next bag is automatically blown and held open. As long as the motion sensor sees movement, the blower stays on. If no movement is seen by the motion sensor, the motion sensor ends an electric signal, thus turning off the blower. In turn, if the motion sensor sees a motion, an electric signal is sent to the blower and turns the bagger back on.
