Abstract
A device and a system for positioning work pieces having cylindrical and/or hollow conical bodies, to be processed in workstations. The system comprises at least a first and a second independent positioning devices for positioning and driving in rotation the work pieces to be processed; each positioning device for a base frame provided with two roll groups for supporting the work piece to be processed, each provided with parallely arranged rolls. One or both of roll groups are movable in horizontal and/or vertical direction with respect to the base frame; a gear motor is operatively connected to the roll of at least one of the roll groups for drivingly rotate the work piece to be processed.
Claims10
A positioning device for positioning and driving in rotation a work piece of medium or large dimension to be worked, having a circular shape, characterized by comprising:
- a longitudinally extending base frame;
- first and second spaced apart roll groups on the base frame, each roll group provided with a support roll for the work piece, having a rotational axis, at least one of said roll groups being movably supported in the longitudinal direction of the base frame, at a right-direction to the rotation axis of roll;
- a drive unit operatively connected to the roll of at least one of the roll groups, to drive in rotation the work piece to be processed;
- and
- control means conformed to horizontally and/or vertically move the roll groups in respect to the base frame.
A system for positioning and driving in rotation circular work pieces, according to which at least two work pieces having hollow bodies are supported in an aligned condition and are driven to rotate during processing, the system comprising:
- a plurality of positioning devices, in which each positioning device comprises first and second roll groups each provided with a support roll;
- and control means for horizontally and/or vertically moving at least one of said roll groups;
- a drive unit for rotation of the support roll of at least one of the roll groups of each positioning device;
- and
- an electronic control unit operatively connected to said control means and to the drive units of the positioning devices, said electronic control unit being conformed and programmable for adjusting the horizontal and/or vertical position of the roll groups, respectively the rotation speed of the driven support rolls.
