Closure checking apparatus for bagged goods

摘要

An apparatus checks a closure on an end of a bag having loosely packed goods contained therein. A first conveyor extends the length of the apparatus. Second and third conveyors are positioned adjacent one side of the first conveyor. A gap is defined between the second conveyor and the third conveyor. Adjacent portions of the first conveyor and second conveyor are coplanar to define a first surface moving in the same direction at the same speed that fully supports the bag moving thereon. Adjacent portions of the first conveyor and the third conveyor are coplanar to define a second surface moving in the same direction at the same speed as the first surface that also fully supports the bag moving thereon. The first conveyor partially supports the bag such that the end thereof and a portion of the loosely packed goods contained in the bag are unsupported by the first conveyor in the area of the gap. A plate is mounted above the first conveyor for applying a downward friction pressure to the bag as the bag moves on the first conveyor in the area of the gap. As a result, the bag is caused to rotate and a portion of the goods fall out of the end of the bag if the closure is not secure. A detector is arranged in the area of the gap for detecting any goods falling out of the end of the bag. An ejector is coupled to the detector for removing any failed bag from the second surface in response to a reject signal from the detector.
