Abstract
An improved apparatus and method are disclosed for winding and wrapping rolls of web material or other objects, in which the roll (10) is wrapped prior to removal from the turret winding machine (96). A roll (16) of stretch wrap material is traversed, swiveled and tilted beside the rotating roll (10) or other object to be wrapped under the control of a traverse motor (144), swivel motor (178) and tilt motor (192) which are actuated in proportion to the speed of rotation of roll (10). For improved accuracy of wrapping, roll (16) of wrap material preferably is located along the swivel axis of the apparatus.
Claims15
Apparatus for winding and stretch wrapping rolls of web material, comprising:
- a rotatable turret assembly;
- a plurality of first means, mounted at circumferentially spaced locations on said turret assembly, for independently supporting and rotating at each of said locations a core on which said web material is to be, is being or has already been wound;
- second means, positioned in proximity to said turret assembly, for applying a stretch wrap to a first roll while said first roll is supported and rotated by one of said first means;
- and
- third means, operatively connected to said turret assembly and said first and second means, for causing said first roll to be wound by one of said first means, for thereafter rotating said turret assembly to position said first roll at said second means and to position a core for winding of a second roll at another of said first means, and for thereafter (a) actuating said one of said first means and said second means to rotate and wrap said first roll and (b) actuating said another of said first means to wind said second roll while said first roll is being rotated by said one of said first means and wrapped by said second means.
A method for winding and stretch wrapping rolls of web material, comprising the steps of:
- providing a rotatable turret assembly;
- providing a plurality of first means, mounted at circumferentially spaced locations on said turret assembly, for independently supporting and rotating at each of said locations a core on which said web material is to be, is being or has already been wound;
- providing second means, positioned in proximity to said turret assembly, for applying a stretch wrap to a first roll while said first roll is supported and rotated by one of said first means;
- winding said first roll of such web material on one of said first means;
- after said winding, rotating said turret assembly to position said first roll at said second means and to position a core for winding of a second roll on another of said first means;
- after rotating said turret assembly, applying stretch wrap to said first roll while rotating said first roll with said one of said first means;
- and
- winding said second roll on said another of said first means while said first roll is being rotated by said one of said first means and wrapped by said second means.
In an apparatus for stretch wrapping a body having a side surface extending between end surfaces, said apparatus being of the type including means for supporting and rotating said body about a first longitudinal axis thereof, a roll of stretch wrap material having a second longitudinal axis, means for supporting said roll of wrap material for rotation about said second longitudinal axis, means for traversing said means for supporting said roll of wrap material along a path substantially parallel to said first longitudinal axis, means for moving said means for supporting said roll of wrap material about a swivel axis substantially perpendicular to said path and means for moving said means for supporting said roll of wrap material about a tilt axis substantially perpendicular to said swivel axis and to said second longitudinal axis, whereby said stretch wrap material can be applied in a spiral pattern around said side surface and across said end surfaces while said body is rotated about said first longitudinal axis and said means for supporting said roll of wrap material is moved along said path, about said swivel axis and about said tilt axis, the improvement comprising:
- a swivel bearing having said swivel axis;
- first means for mounting one race of said swivel bearing to said means for traversing;
- a frame member;
- second means for mounting the other race of said swivel bearing to said frame member;
- third means for mounting said means for supporting said roll of wrap material on said frame member to position said roll of wrap material along said swivel axis with said swivel axis passing through said roll of wrap material;
- and
- said means for moving about said swivel axis being operatively connected to rotate said frame member of said swivel bearing about said swivel axis.
