Abstract
An automatic bag opening device includes a housing having a bag intake opening for receiving a filled shipping bag. A bag assist plate forms a chute, allowing the bag to slide down and rest on a bag rest. A hollow penetrator penetrates the bag to hold it in place while a bottom of the bag is cut. The bag rest moves away from the bottom of the bag, allowing the contents of the bag to spill out. An air blast through the penetrator helps the bag empty. Additional air blasts hit and shake the bag, knocking the contents loose. A bag pusher pushes the empty bag into a set of rollers, folding the empty bag in half, and discharging the bag outside the housing. A dust collector within the housing collects loose dust, thereby enhancing safety and cleanliness of the workplace.
