Abstract: The present invention relates to compact palletizers that include a stretch-wrap operation as the pallet is built. A four-sided compaction mechanism compresses the rough-built load to the final pallet size and then the entire layer is released to the pallet. Individual items or group of items are picked and placed onto a layer support device in a loose orientation. The loose orientation enables a much faster palletizing operation because the robotic arm that pick-and-places the item, the items, or the row of items, can travel much faster as it does not have to precisely locate the item, items, or row of items. During the time that a layer is being loosely constructed on the layer support device concurrent wrapping can occur.

Abstract: The present invention relates to compact palletizers that include a stretch-wrap operation as the pallet is built. Specifically, the present invention uses a robot to place items from a fixed infeed elevation either above or, alternatively, below the height of the finished load. A four-sided compression mechanism compresses the rough-built load to the final pallet size and then the entire layer is released to the pallet. Individual items or group of items are picked and placed onto a layer support device in a loose orientation. The loose orientation enables a much faster palletizing operation because the robotic arm that pick-and-places the item, the items, or the row of items, can travel much faster as it does not have to precisely locate the item, items, or row of items. During the time that a layer is being loosely constructed on the layer support device concurrent wrapping can occur.

Abstract: A load balancing arm is shown and described as having improved control including a programmable control element and electronic air regulation to provide precise and controllable lifting force on a load. The disclosed load balancing arm responds to slight operator applied force to aid in movement of the load in overcoming system hysteresis, friction and load inertia without requiring the operator to apply a sufficiently large magnitude force to overcome such counteracting forces in the system. The disclosed load balancing arm further includes automatic load weight detection sensors for accommodating variation in load weights while applying a lifting force to the load which substantially equals the weight of the load. This allows the operator to move the load freely throughout a work space.
