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.
Claims26
A system for preparing winding mandrels with winding cores inserted thereover on which to form reels of web material, the system comprising:
- a robot;
- a cutting unit for cutting a tube for forming tubular winding cores of settable axial length;
- a station for mutually axially distancing the tubular winding cores inserted on a winding mandrel;
- an insertion unit for inserting the winding mandrels into a series of previously cut and axially aligned tubular winding cores, wherein said robot is arranged and controlled for:
- extracting said mandrel from previously formed reels of web material;
- inserting said mandrel in a set of said previously cut and axially aligned tubular winding cores;
- transferring said winding mandrel with said previously cut and axially aligned tubular winding core inserted thereover into a rewinding machine to form said reels of web material around said previously cut and axially aligned tubular winding cores.
A method for preparing winding mandrels, whereon are inserted and locked tubular winding cores, the method comprising the steps of:
- axially approaching tubular winding cores to each other;
- 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;
- after inserting said winding mandrel into said tubular winding cores, mutually distancing said winding cores before insertion into a rewinding machine, and transferring said winding mandrel with said tubular winding cores inserted thereof into the rewinding machine to form reels of web material around said tubular winding cores, wherein said winding mandrel is extracted from said previously formed reels of web material and inserted in said tubular winding cores via a handling robot.
A system, comprising:
- a rewinding machine;
- a winding mandrel removably connected to one or more previously formed reels of web material;
- a robot, said robot removing said wind mandrel from said one or more previously formed reels of web material;
- a tube;
- a cutting unit, said cutting unit receiving said tube and cutting said tube to form cut tubular winding cores;
- an insertion unit, said insertion unit receiving said cut tubular winding cores, wherein said cut tubular winding cores are axially arranged via said insertion unit to form cut and axially arranged tubular winding cores, said robot inserting said winding mandrel in said cut and axially arranged tubular winding cores at said insertion unit;
- a station, said station receiving said winding mandrel with said cut and axially arranged tubular winding cores connected to said winding mandrel, wherein one or more of said cut and axially arranged tubular winding cores on said winding mandrel are moved in an axial direction of said winding mandrel via said station to form cut, axially arranged and axially moved tubular cores, said robot transferring said winding mandrel, with said cut, axially arranged and axially moved tubular winding cores connected to said winding mandrel, into said rewinding machine to form new reels of web material about said cut, axially arranged and axially moved tubular winding cores.
