Roller cage for a profiling line

Abstract

A roller cage for a profiling line, comprising: a support frame (F 1 ); a first motor equipped with a first substantially horizontal spindle ( 12 ) that projects in a cantilever fashion externally to a shoulder (S 1 ) of the support frame (F 1 ) into an operating space of the line; a first transverse roller ( 13 ), assembled directly on the first spindle ( 12 ); a movable frame (F 2 ), with which an upright first roller ( 33 ) is associated, rotating about a first shaft ( 32 ) which projects in a cantilever fashion from the movable frame (F 2 ); the movable frame (F 2 ) is movable between an operating position, in which the first shaft ( 32 ) assumes a substantially vertical position, and a non-operating position, in which the first shaft ( 32 ) assumes a substantially horizontal position and is facing the same way as the first spindle ( 12 ), towards the operating space of the line.

1 . A roller cage for a profiling line, characterised in that it comprises:
 a support frame (F 1 );   a first motor associated with a first substantially horizontal spindle ( 12 ) that projects in a cantilever fashion externally to a shoulder (S 1 ) of the support frame (F 1 ) into an operating space of the line;   a first transverse roller ( 13 ), assembled directly on the first spindle ( 12 );   a movable frame (F 2 ), with which an upright first roller ( 33 ) is associated, rotating about a first shaft ( 32 ) which projects in a cantilever fashion from the movable frame (F 2 );   
       the movable frame (F 2 ) is movable between an operating position, in which the first shaft ( 32 ) assumes a substantially vertical position, and a non-operating position, in which the first shaft ( 32 ) assumes a substantially horizontal position and is facing the same way as the first spindle ( 12 ), towards the operating space of the line. 
     
     
         2 . The cage according to  claim 1 , comprising a second upright roller ( 43 ), rotatably associated with a second shaft ( 42 ), substantially parallel to the first shaft ( 32 ) and projecting in a cantilever fashion from the movable frame (F 2 ). 
     
     
         3 . The cage according to  claim 1 , wherein the movable frame (F 2 ) comprises a cross member ( 30 ) which can rotate about an axis between the operating position and the non-operating position, and wherein the first shaft ( 32 ) is connected in a cantilever fashion to the cross member ( 30 ). 
     
     
         4 . The cage according to  claim 1 , wherein the movable frame (F 2 ) comprises a cross member ( 30 ) which can rotate about an axis between the operating position and the non-operating position, and wherein the first shaft ( 32 ) and the second shaft ( 42 ) are connected in a cantilever fashion to the cross member ( 30 ). 
     
     
         5 . The cage according to  claim 1 , wherein the movable frame (F 2 ) is placed next to the load-bearing frame (F 1 ). 
     
     
         6 . The cage according to  claim 1 , comprising a second motor associated with a second spindle ( 22 ) that projects in a cantilever fashion externally to the shoulder (S 1 ) of the support frame (F 1 ); a second transverse roller ( 23 ) mounted directly on the second spindle ( 22 ). 
     
     
         7 . The cage according to  claim 1 , wherein the support frame (F 1 ) comprises two shoulders (S 1 , S 2 ) between which a non-operating space is defined, and wherein the first roller ( 13 ) and, if present, the second roller ( 23 ), are located externally to the frame (F 1 ), i.e. they are on the side of the shoulder (S 1 ) that is not facing towards the other shoulder (S 2 ). 
     
     
         8 . The cage according to  claim 1 , wherein the position of each motor is adjustable along a vertical direction and/or along a horizontal direction. 
     
     
         9 . The cage according to  claim 1 , wherein each motor is a permanent magnet motor, preferably of the torque type. 
     
     
         10 . A profiling line, comprising a plurality of roller cages (G) according to  claim 1 , aligned along a longitudinal direction (Y). 
     
     
         11 . The profiling line according to  claim 10 , comprising a changing device ( 50 ), configured for replacing each roller ( 13 , 23 , 33 , 43 ) of the cages (G) with another roller. 
     
     
         12 . The profiling line according to  claim 11 , wherein the changing device ( 50 ) comprises an operating head ( 51 ), movable in the space so as to be able to reach each roller ( 13 , 23 , 33 , 43 ) of the cages (G). 
     
     
         13 . The profiling line according to  claim 12 , wherein the operating head ( 51 ) is equipped with a means for disassembling and reassembling a roller ( 13 , 23 , 33 , 43 ) on the respective spindle or shaft. 
     
     
         14 . The profiling line according to  claim 11 , comprising a magazine ( 60 ) for a plurality of rollers (R) interchangeable with the rollers ( 13 , 23 , 33 , 43 ) of the cages (G).
