Machine for winding a wire from a rolling mill into a coil

Abstract

A machine for winding a wire from a rolling mill into a coil contains spindle with a seat for threading the head end of the wire with related binding devices. The threading seat and the binding devices are linked to an independent cover module that is coupled moveably to the spindle.

1 - 10 . (canceled) 
     
     
         11 . A machine for winding a wire from a rolling mill into a coil, the machine comprising:
 binding means;   an independent cover module; and   a spindle having a seat for threading a head end of the wire with said binding means, said seat and said binding means are linked to said independent cover module connected moveably to said spindle.   
     
     
         12 . The machine according to  claim 11 , further comprising a movement structure, said independent cover module is supported by said movement structure cooperating with said spindle to move said independent cover module between a coupled operating position for rotation with said spindle for forming coils, and a non-operating position removed from said spindle for removing the coil formed. 
     
     
         13 . The machine according to  claim 12 , wherein said independent cover module is supported by said movement structure in a rotating and pivoting manner. 
     
     
         14 . The machine according to  claim 13 ,
 further comprising a motor;   further comprising a pair of lateral support pillars;   further comprising a pair of lateral hydraulic actuators; and   wherein said movement structure has a base bearing a track and a frame on said track controlled by said motor to move forwards and backwards in directions of an arrow, said track connected pivotally at a rear to said pair of lateral support pillars, while at a front said track is connected pivotally to said pair of lateral hydraulic actuators which are in turn connected pivotally to said base.   
     
     
         15 . The machine according to  claim 14 , wherein said independent cover module is supported in front of said frame and is engaged by rotation around said spindle, in an easily removable manner. 
     
     
         16 . The machine according to  claim 15 , further comprising a male male-female joint and said independent cover module is coupled to said spindle using said male male-female joint. 
     
     
         17 . The machine according to  claim 16 , wherein said male male-female joint has a male element, connected axially to said spindle, and a matching female element having an inside body, and disposed centrally on said independent cover module, which rotates inside said body of said female element. 
     
     
         18 . The machine according to  claim 17 , further comprising pairs of arms, said independent cover module is mounted on a free end of said frame, in a self-centering and pivoting manner, by means of said pairs of arms, said arms are connected pivotally at one end to said frame, and at an opposite end, to said body of said female element of said male male-female joint connecting said independent cover module to said spindle. 
     
     
         19 . The machine according to  claim 15 ,
 wherein said independent cover module has underlying elastic pins;   further comprising diametrically opposed pairs of hydraulic actuators; and   further comprising a pivoting disk, said independent cover module is linked, at a top, to said pivoting disk supported by said frame by said diametrically opposed pairs of hydraulic actuators, said diametrically opposed pairs of hydraulic actuators are connected pivotally to said frame and to said pivoting disk and cooperate with said underlying elastic pins of said independent cover module, acting on top coils of the wire to prevent any hindrance when removing said independent cover module from said spindle.   
     
     
         20 . The machine according to  claim 11 , further comprising an annular collar disposed underneath said independent cover module and defining said seat being an annular seat for threading and binding a first coil of the wire against said binding means being wedge-shaped surfaces defined by an underside of said independent cover module itself, and by an internal surface of said annular collar.
