} the principles in the innovation wrapping machine

An apparatus is provided for wrapping a load with packaging material, according to the invention. As displayed in Fig. 1, the apparatus for wrapping a lot with product packaging material involves stretch wrapping apparatus 100.

A dispenser is provided for dispensing and stretching packaging material, according to the present invention. As displayed in Fig. 1, the dispenser consists of stretch wrap dispenser 102, together with a mast 104, a roll carriage 106, and a motor and belt travel 108 for up and down placing roll dispenser 106 on mast 104 to spirally wrap the stress. Roll carriage 106 might include a framework 110, a film roll help 112 and a variety of rollers 114, probably such as prestretch rollers, to placement, distribute, and stretch a packing material this kind of stretch wrap film 116 being dispensed from stretch wrap film roll 118. Many other packaging resources for example banding, netting and strapping or tape bring nicely.

The apparatus includes means for providing relative rotation between the dispenser and the load to wrap packaging material around the load, according to the present invention. As shown in Fig. 1, the path for delivering general rotation features a motor unit driven turntable 120 installed on basic 122 to spin fill 124 of weight devices 126 about a top to bottom axis 128.

Otherwise, the method for delivering comparable rotation involving the dispenser along with the weight can include an set up wherein the film dispenser involves the stress, so the dispenser might be maintained by way of a engagement ring or arm or any other layout. The relative rotation may occur about a vertical axis as shown for pallet loads, or may occur around a horizontal axis for bundling operations.

A retainer is provided for holding a leading end of the packaging material while initially wrapping the load, and for automatically releasing the packaging material in response to unpowered actuation, according to one aspect of the invention.

As demonstrated in Fig. 1, the retainer features a gripper clamp 130, which happens to be shown in more detail by Figs. 2 through 5. Gripper clamp 130 can be seen to feature an elongated associate for example tube 132 using a leading dish 133 welded to just one end of tube 132 to form 1 jaw bone 134, as well as a rod 131 slidable inside of tube 132 and welded to a secondly platter 135 to create a secondly mouth 136 such that jaws 134 and 136 have opposite surfaces that could clamp wrapping material between them preventing activity of the wrapping material relative to the jaws.

Tube 132 carries a pivot 138 say for example a pin or bolt, having a pivot axis 140, enabling tube 132 to pivot relative to basic 142 involving the typically horizontal placement shown in Fig. 2, with jaws 134 and 136 inside the open up place, with an intermediate situation shown in Fig. 3, for the typically straight position displayed in Fig.

4, using the jaws 134 and 136 within a closed placement.
