A 300 automatic pallet wrapping machine
The applicant has recognized the limitations and shortcomings of the previous extensional packaging machines, including the inability to pack long items, high cost, large space utilization, and lack of flexibility due to the inability to move. In addition, many stretch wrapper machines have limitation on the weight of at least one size and the load to be packed. The invention provides a track stretching winding machine, which overcomes most of these limitations, if not all.
More specifically, the invention provides a kind of rail stretching winding machine, which includes a stretching packing distributor around a load in a packaging plane, and can be moved in the direction of travel usually in the direction of the packing plane transverse. This enables the machine to pack the loads of different sizes. The machine does not support the load, so the machine is not limited by the weight of the load. Besides, because the distributor can move along the stroke direction, the load length is not the limit of the machine.
In one embodiment of the invention, the distributor is mounted on a revolving ring, and the load is extended to the ring for packaging. The ring defines the packing plane and is mounted on the track to move in the moving direction. The only limitation on the size of the load is that it must be suitable for the loop.
By moving the packing ring back and forth on the track, the machine can wrap up any material that has the smallest or no movement of the material handling equipment. If the load is very long (longer than the ring in the orbit), additional orbit can be added, and the invention can pack almost unlimited length of load without moving the load.
Therefore, the machine moves the load of packaging material on horizontal axis and vertical axis, and does not move load. The weight of the load is instantaneous to the machine. If the material handling equipment can increase the load, the machine can pack it.
