ABSTRACT:
An automatic bag opening apparatus for sequentially opening at least one bag, preferably a mesh bag, comprising a frame, a wicket for holding the bag wherein the mesh bag adjacent the forward end of the wicket is the outermost mesh bag, a first clamp disposed adjacent the forward end of the wicket, an air dam slidably mounted to the frame, an opener clamp slidably mounted to the frame, and a nozzle or other means for directing a pressurized fluid through at least a portion of the first, or outer, side of the outermost mesh bag adjacent its open end and onto the air dam. In operation, the first clamp is positioned in contact with the outermost mesh bag, the air dam is located adjacent the open end of the first side of the outermost mesh bag the pressurized fluid is directed through a portion of the open end of the first side of the outermost mesh bag adjacent its open end and onto the air dam, which causes the portion of the mesh bag through which the pressurized fluid is directed to move towards the air dam. The next step involves moving the opener clamp to grasp the portion of the first side of the outermost bag and then moving the opener clamp a desired distance away from the forward end of the bag holding means, whereby the outermost mesh bag is opened by the opener clamp grasping its first side and the first clamp holding its second side. The present invention also encompasses a second clamp disposed on the frame for use when sequentially opening a plurality of bags.
