Roller cage for a profiling line

Abstract

A roller cage for a profiling line, comprising: a support frame (F 1 ) that entirely delimits a non-operating area (A 1 ) which is external to the line; at least a motor ( 11 ) provided with a spindle ( 12 ) protruding externally of the non-operating area (A 1 ); at least a shaped roller ( 13, mounted directly on the spindle ( 12 ) and arranged inside an operating area (B) of the line.

1 . A roller cage for a profiling line, characterized in that it comprises: a support frame (F 1 ) that entirely delimits a non-operating area (A 1 ) which is external to the line; at least a motor ( 11 ) provided with a spindle ( 12 ) protruding externally of the non-operating area (A 1 ); at least a shaped roller ( 13 ), mounted directly on the spindle ( 12 ) and arranged inside an operating area (B) of the line. 
     
     
         2 . The cage according to  claim 1 , wherein the spindle ( 12 ) is supported solely by the motor ( 11 ) and has a free end. 
     
     
         3 . The cage according to  claim 1 , comprising a second motor ( 21 ) provided with a spindle ( 22 ) protruding externally of the non-operating area (Al); a second roller ( 23 ), mounted directly on the spindle ( 22 ) coupled with the second motor ( 21 ) and arranged inside the operating area (B) of the line. 
     
     
         4 . The cage according to  claim 3 , wherein the spindle ( 22 ) is supported solely by the second motor ( 21 ) and has a free end. 
     
     
         5 . The cage according to  claim 1 , wherein the support frame (F 1 ) comprises two shoulders (S 1 ,S 2 ) between which the non-operating area (A 1 ) is defined, and wherein the first roller ( 13 ) and, if present, the second roller ( 23 ), are located externally of the frame (F 1 ), that is, they are located on the side of the shoulder (S 1 ) that is not facing the other shoulder (S 2 ). 
     
     
         6 . The cage according to  claim 3 , wherein the spindles ( 12 , 22 ) of the two motors ( 11 , 21 ) are substantially parallel to each other. 
     
     
         7 . The cage according to  claim 1 , comprising a second support frame (F 2 ), which entirely delimits a non-operating area (A 2 ) external to the line; two motors ( 31 , 41 ) provided with a respective spindle ( 32 , 42 ) protruding externally of the non-operating area (A 2 ); a shaped roller ( 33 , 43 ), directly mounted on each spindle ( 32 , 42 ) and arranged inside the operating area (B) of the line. 
     
     
         8 . The cage according to  claim 7 , wherein the spindles of the motors ( 32 , 42 ) are substantially parallel to each other. 
     
     
         9 . The cage according to  claim 1 , wherein the position of each motor ( 11 , 21 , 31 , 41 ) is adjustable along a vertical direction. 
     
     
         10 . The cage according to  claim 1 , wherein the position of at least one motor ( 11 , 21 , 31 , 41 ) is adjustable along a horizontal direction. 
     
     
         11 . The cage according to  claim 1 , wherein each motor ( 11 , 21 , 31 , 41 ) is a permanent magnet motor. 
     
     
         12 . The cage according to  claim 1 , wherein each motor ( 11 , 21 , 31 , 41 ) is a motor of the torque type. 
     
     
         13 . A profiling line comprising a plurality of roller cages (G) according to  claim 1 , aligned along a longitudinal direction (Y). 
     
     
         14 . The profiling line according to  claim 13 , comprising an automatic alignment device, configured to adjust the position of each shaped roller ( 13 , 23 , 33 , 43 ) relative to the longitudinal direction (Y). 
     
     
         15 . The profiling line according to  claim 13 , wherein each roller cage (G) comprises a dimensional detector, configured to detect one or more dimensions of the profile (P) exiting the roller cage (G), said dimensional detector being connected to the automatic alignment device.
