The Roll Handler grips the inside of fibreboard or plastic roll cores. The roll is gripped and tilted 90 degrees pneumatically. The roll handler shown is mounted on a manipulator, but it can also be hung from a crane.
Handling rolls with a manipulator is very convenient because the roll can be brought to a perfect horizontal or vertical position regardless of the size or weight of the roll.
When the roll handler is hung from a crane and 90 degree tilting is required, a load leveller can be added depending on the size and weight of the roll.
Rolls can be picked up vertically ("eye-to-the-sky") or horizontally. Rolls can be pulled from a mandrel or set on a mandrel.
The weight and size of roll that can be picked up is limited only by the inside diameter of the roll relative to its length. If air pressure is lost while the roll is hung vertically, a pilot-operated check valve will hold the load for long enough to bring it to the floor.
The length of the roll handler's shaft can be varied by pulling a pin and swapping shafts.
