Bilateral machine for processing glass panes shaped like a parallelogram with non-right angles

Abstract

A bilateral machine for processing panes shaped like a parallelogram with non-right angles, comprising an input station downstream of which there is a first bilateral unit which leads to an angle transfer assembly which is arranged upstream of a second bilateral unit, the angle transfer assembly comprising elements for rotation on the plane of arrangement of the pane being processed and elements which can be activated selectively for the alignment of the unprocessed edge of the pane being processed.

1 . A bilateral machine for processing panes shaped like a parallelogram with non-right angles, comprising an input station downstream of which there is a first bilateral unit which leads to an angle transfer assembly which is arranged upstream of a second bilateral unit, wherein said angle transfer assembly comprises means for rotation on a plane of arrangement of a pane being processed and means which can be activated selectively for the alignment of unprocessed edges of said pane being processed.  
   
   
       2 . The bilateral machine according to  claim 1 , wherein said angle transfer assembly comprises means for transfer in a direction of motion of the pane on said first bilateral unit which are adapted to provide said means for rotation on the plane of arrangement of the pane being processed.  
   
   
       3 . The bilateral machine according to  claim 2 , wherein said means for transfer in the direction defined by said first bilateral unit comprise belts with variable vertical positioning which are interposed between rollers for the transfer of said pane being processed along a direction which is substantially perpendicular to a transfer direction formed on said first bilateral unit.  
   
   
       4 . The bilateral machine according to  claim 1 , wherein said means for the alignment of the non-processed edge comprise abutment rollers which protrude on command with respect to a plane formed by said belts in order to provide an abutment for said pane being processed upon actuation of said belts in a direction which is opposite with respect to a direction for transfer from said first bilateral unit to said angle transfer assembly.  
   
   
       5 . The bilateral machine according to  claim 4 , further comprising a positioning bar from which said abutment rollers protrude radially, an actuation element being further provided for lowering and lifting said abutment rollers with the rotation of said positioning bar.  
   
   
       6 . A method for processing panes shaped like a parallelogram with non-right angles, comprising the steps of: arranging a pane being processed on a first bilateral unit so that a leading vertex is arranged on an opposite side with respect to an abutment edge formed by processing heads of said first bilateral unit, processing first two sides, transferring the pane onto an angle transfer assembly, provided with belts with a vertically adjustable working surface, making a rear end of the pane being processed pass beyond a processing line of the other edge, which is formed by a second bilateral unit, lifting a plurality of abutment rollers which are mutually aligned, reversing the motion of said belts with rotation by slippage of the pane on the belts with arrangement of the other sides to be processed in alignment with said abutment rollers, lowering said belts below a working surface and transferring said pane onto the second bilateral unit for processing the other two sides.  
   
   
       7 . The method according to  claim 6 , wherein the processing of the short sides of said pane is performed on said first bilateral unit.
