FleetwoodGoldcoWyard, A Division of Barry-Wehmiller Companies, Inc: FleetwoodGoldcoWyard Introduces New Robotic Unwrapper
The Robotic Unwrapper removes stretch wrap material from a pallet load prior to depalletizing.
The system has the capability of unwrapping virtually any stretch-wrapped load, including glass, plastic bottles and cans as well as shrink-wrapped cardboard boxes. The robot removes the stretch wrap by applying a focused heat-source to the stretch wrap material on the load.
The stream of heated air is directed at the stretch-wrapped load and guided by the robot to assure the correct distance and speed is achieved to weaken the molecular bond of the stretch wrap, causing it to part. A fixed vacuum arm holds one end of the parted wrap as the robot-guided heat gun completely parts the wrap. Once the wrap is parted, the end-of-arm-tooling on the robot clamps the wrap being held by the fixed vacuum arm and places it between a set of rollers. The rollers pinch the wrap, compressing it, and as the pallet rotates, they continue to collect the waste wrap and feed it into the customer’s supplied waste bin or vacuum takeaway system.
The Robotic Unwrapper eliminates the need for an operator to manually cut stretch wrap, unwrap loads and collect and dispose of removed wrap. The Robotic Unwrapper utilizes a very limited amount of floor space and is easier to maintain due to fewer moving parts. Because of the robot’s flexibility and capability, it is able to handle additional over-wrap at the top of the load.
