Abstract:
A revolver-type coiler for winding of a band-type product around one of at least two chucks comprising:a revolving mounting structured to rotate around a central axis on a fixed frame,at least two winding chucks extending cantilever on a same side of the revolving mounting, from a first end embedded on the mounting up to a second opposite end, each chuck having a shaft and rotating on the revolving mounting around an axis, out of center of the revolving mounting and parallel to the central axis,means for selective control of the rotation of one of both winding chucks around a respective axis,means for controlling the rotation of the revolving mounting around said central axis, for selective positioning of a first winding chuck into a first winding starting position, then the switching of the winding chuck from the first position to at least one second position for completion of winding and unloading of the coil, with simultaneous return of the second unloaded chuck from the second position to the first position,and a continuous supporting device of the second end of the shaft of each winding chuck opposite to the revolving mounting from the first starting position to the completion of winding position, said support device comprising at least one rotary removable resting member for said second end of the shaft resting on the fixed frame, and a supporting means installed to rotate together with the revolving mounting around the central axis of the revolving mounting for supporting the at least one rotary removable resting member,said supporting means of the removable resting member comprising:at least one resting stem having a first end embedded in the revolving mounting and extending along a direction parallel to the central axis,at least one supporting arm which is articulated on said at least one resting stem, around an axis parallel to the central axis, and at a distance greater than the width of a coil,and means for controlling the rotation of said at least one supporting arm around said axis between a first engagement position of the removable resting member on the second end of the chuck and a second disengagement position of said resting member,the supporting arm being offset in said second position at an angle with respect to the chucks so that the resting member is moved away sufficiently far from the chucks to enable the unloading of a completely wound coil.
