ABSTRACT

A suspendable apparatus for the lifting, rotating and transferring of
essentially smooth-walled cylindrical objects, where such apparatus is
preferably an air cylinder. The apparatus comprises a vertically oriented
lifting mechanism consisting of a lifting chamber fixed at its upper end and
movable at its lower end, with power to the air cylinder in the chamber.
Additionally, there is a rotating mechanism for gripping and rotating the
cylindrical object, such as a drum or paper roll. The rotating mechanism is
mounted on a fixed arm secured to the lower end for movement therewith. The
rotating mechanism further includes a housing having a fixed end secured to
the fixed arm and a second end remote therefrom. The second end includes a
pair of movable gripping arms mounted for rotational movement about the second
end, where the arms include at least two arcuate shaped cups positioned to
apply a vacuum against the wall of the cylindrical object. Finally, a
fail-safe sensing system is incorporated herein which detects a pre-determined
weight of the cylindrical object, whereby at a value above this pre-determined
weight, the lifting and vacuum gripping system hereof cannot be inadvertently
or manual terminated.
