Thin metal strip winding method and thin metal strip winding system

Abstract

A thin metal strip winding method includes: a step of causing a thin metal strip to fly from a flight tube; a cutting and grasping step of cutting and grasping any portion of the thin metal strip flying from the flight tube; a thin metal strip connecting step of connecting the any portion of the thin metal strip cut and grasped in the cutting and grasping step and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.

What is claimed is: 
     
         1 . A thin metal strip winding method comprising:
 a step of causing a thin metal strip to fly from a flight tube;   a cutting and grasping step of cutting and grasping any portion of the thin metal strip flying from the flight tube;   a thin metal strip connecting step of connecting the any portion of the thin metal strip cut and grasped in the cutting and grasping step and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and   a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.   
     
     
         2 . A thin metal strip winding system comprising:
 a flight tube which causes a thin metal strip to fly;   a winding roll rotation unit on which a winding roll with a thin metal strip remaining thereon is set;   a cutting-grasping unit which cuts and grasps any portion of the thin metal strip flying from the flight tube;   a connecting unit which connects the any portion of the thin metal strip cut and grasped by the cutting-grasping unit and a leader as a ribbon, the leader being a to-be-connected portion of the thin metal strip remaining on the winding roll; and   a winding unit which winds up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.   
     
     
         3 . The thin metal strip winding system according to  claim 2 , wherein
 the cutting-grasping unit has
 a cutter which cuts the ribbon; and 
 a stopper which holds the ribbon in a state where the ribbon is disposed so as to surround the cutter, and 
   the cutting-grasping unit cuts the ribbon by moving the cutter with the ribbon held by the stopper.   
     
     
         4 . The thin metal strip winding system according to  claim 3 , wherein
 the connecting unit is configured to connect the leader and the ribbon in a state where the leader and the ribbon are disposed vertically, and   the cutting-grasping unit cuts the ribbon near the connecting unit and places one end portion of the cut ribbon around a remaining tip portion of the leader.   
     
     
         5 . The thin metal strip winding system according to  claim 3 , wherein
 the connecting unit is configured to connect the leader and the ribbon in a state where the leader and the ribbon are disposed horizontally, and   the cutting-grasping unit cuts the ribbon near the connecting unit and places one end portion of the cut ribbon around a remaining tip portion of the leader.
