Apparatus for transporting printing paper rolls

Abstract

An apparatus for transporting printing paper rolls includes a main frame and a satellite frame. The main frame is movable in a first direction along a press, either on its own or together with the satellite frame. The satellite frame is movable in a second direction, approximately perpendicular to the first direction, and independently of the main frame. A lifting device is arranged in the main frame to lift the satellite frame accommodated in the main frame off a floor. The lifting device is constructed such that a satellite frame can be lifted by the main frame to a level above a satellite frame positioned on the floor.

1 . An apparatus for transporting printing paper rolls in a press, comprising: 
 a main frame and a satellite frame, said main frame being movable in a first direction along the press with or without said satellite frame, said satellite frame being movable in a second direction approximately perpendicular to said first direction, independently of said main frame; and    a lifting device in said main frame, said lifting device being arranged and dimensioned for lifting the satellite frame, when said satellite frame is accommodated in said main frame, from a first position in which said satellite frame is on a floor beneath said main frame to a second position in which said satellite frame is at a level above said satellite frame in the first position.    
     
     
         2 . The apparatus of  claim 1 , wherein said main frame comprises vertical beams, said lifting device being lifted and lowered in the vertical direction along said vertical beams of said main frame.  
     
     
         3 . The apparatus of  claim 1 , wherein said lifting device includes lifting platforms arranged on both sides of said satellite frame for receiving said satellite frame thereon when said satellite frame is accommodated in said main frame.  
     
     
         4 . The apparatus of  claim 3 , further comprising lifting cylinders connected in said main frame between said main frame and respective ones of said lifting platforms for lifting and lowering said lifting platforms.  
     
     
         5 . The apparatus of  claim 3 , wherein main frame comprises vertical beams and lifting frames arranged on said vertical beams, said lifting platforms are mounted via said lifting frames on said vertical beams.  
     
     
         6 . The apparatus of  claim 4 , wherein main frame comprises vertical beams and lifting frames arranged on said vertical beams, said lifting platforms are mounted via said lifting frames on said vertical beams, wherein said lifting cylinders act on said lifting frames.  
     
     
         7 . The apparatus of  claim 3 , wherein said lifting platforms are synchronously raised and lowered.  
     
     
         8 . The apparatus of  claim 3 , wherein said lifting platforms are also movable in a horizontal direction.  
     
     
         9 . The apparatus of  claim 8 , wherein the lifting platforms are synchronously movable in the horizontal direction.  
     
     
         10 . The apparatus of  claim 5 , wherein said lifting platforms are lifted and lowered in the vertical direction together with said lifting frames, and said lifting platforms are movable in a horizontal direction with respect to said lifting frames when the satellite frame is lifted off the floor beneath said main frame.
