Abstract
Disclosed is a system to be combined to one or more rewinding machines (1) for forming reels or logs of web material wound around winding mandrels. The system, whose function is to prepare the winding mandrels with the related winding cores positioned thereon, comprises in combination: a robot (5) for extracting winding mandrels (A) from formed reels (BB); a cutting unit (7) for cutting tubes (T) for forming tubular winding cores (AT) of settable axial length; an insertion unit (9), for introducing the winding mandrels into a set of tubular winding cores.
Claims44
A system for preparing winding mandrels on which to form reels of web material, the system comprising:
- a robot for extracting winding mandrels from formed reels;
- a cutting unit for cutting a tube for forming tubular winding cores of settable axial length;
- an insertion unit for inserting the winding mandrels into a series of tubular winding cores.
A method for preparing winding mandrels, whereon are inserted and locked tubular winding cores, the method comprising the steps of:
- extracting a winding mandrel from previously formed reels of web material;
- inserting said mandrel into a set of tubular winding cores previously cut to size and axially aligned;
- transferring the winding mandrel with the tubular winding cores inserted thereover into a rewinding machine to form reels of web material around said tubular winding cores.
A robot for handling expandable winding mandrels, the robot comprising:
- an arm carrying a head with gripping members for gripping the mandrels and an expansion and contraction member for expanding/contracting the winding mandrels, to lock tubular winding cores on said mandrels and unlock said tubular winding cores therefrom.
