Definitions

  • the present invention is concerned with a method for the application of reel end discs in a wrapping line to the ends of a horizontal reel to be wrapped, whereat, for the application of the discs, the reel moves on the wrapping line to the position between end presses and the reel end discs to be applied to the reel ends are fitted onto the faces of the end presses facing towards each other, the end discs being pulled against the faces of the end presses by means of negative pressure, and that the reel end discs are pressed by means of the end presses onto the ends of the reel located between the end presses, and attached to the reel ends, whereupon the end presses are shifted apart from each other and the wrapped reel moves away from between the end presses and a new reel is shifted to the position between the end presses for application of the reel end discs.
  • This method is disclosed in US-A-3 393 492.
  • the method in accordance with the invention is mainly characterized in that the reel end discs are supplied to the end presses from vertical rolls of reel end discs in the form of a band so that the first reel end discs which have been pulled into basic positions by pulling rolls are grasped by means of transfer devices in their basic positions and, by means of the transfer devices and the pulling rolls, the reel end discs whose edge portions are attached to each other, are pulled off the rolls of reel end discs until it is noticed, by means of aligning means, that the next reel end discs are in their basic positions, the first reel end discs are cut loose from the next reel end discs placed in their basic positions, and they are transferred by means of the transfer devices to positions opposite the press faces of the end presses, whereupon, after they have been sucked onto these faces by said negative pressure means, the transfer devices release their grip and move further to their basic positions, and the first reel end discs are attached to the reel ends when the plastic coating on the first reel end discs, placed against the reel ends, melts on heating of the press faces of
  • the wrapping line includes end presses 3, whose press faces 6, facing towards each other, can be heated.
  • the press faces 6 are additionally provided with numerous holes, which are connected to suction channels, through which a negative pressure can be produced at the press faces 6 for the purpose of sucking the reel end discs 4 onto the press faces 6.
  • the end presses 3 can be shifted towards each other to the pressing position and apart from each other to the basic position. Since the end presses 3, their actuating system, the vacuum system, and the system of heating of the press faces 6 involve nothing that was not known in prior art, the end presses 3 have not been illustrated in detail in the drawings, but a highly schematical mode of presentation has been found adequate.
  • the reel wrapping line includes transfer devices 7, by means of which the reel end discs 4 are transferred onto the press faces 6 of the end presses.
  • the transfer device 7 includes a gripper 14, by means of which the edge portion of the reel end disc 4 to be transferred is grasped.
  • the gap of the gripper 14 In the basic position shown in Fig. 2, the gap of the gripper 14 is kept open by a spring 15.
  • the gap of the gripper 14 is closed pneumatically by means of the cylinder- piston device 16.
  • the height position of the gripper 14 has been arranged adjustable. The adjustment of, the height position takes place preferably automatically.
  • the diameter of the reel 1 to be wrapped Preferably, this takes place fully automatically, e.g., by means of a line of photocells.
  • the reel 1 to be wrapped moves to the position between the end presses 3, being supported by the carrier roll reeler 12.
  • the reel 1 to be wrapped moves to the position between the end presses 3, being supported by the carrier roll reeler 12.
  • the reel end discs At both sides of the wrapping line, there are several rolls 5 of reel end discs of different sizes of reel end discs. From among the rolls 5, the correct size of reel end disc is chosen, either manually or by means of some automatic system suitable for the purpose, and the first reel end disc 4 on the 5 is guided around the guide rolls 13 to between the pulling rolls 8.
  • the pulling rolls 8 pull the reel end disc 4 until the aligning means 9 indicate that the first reel end discs 4 are in the basic positions and the pulling rolls stop.
  • the gripper 14 of the transfer device in the basic position is in the open position and, by means of its automatic aligning system, the gripper 14 finds out the correct height position. Once the gap of the gripper 14 is aligned in the correct position, the gripper 14 grasps the edge of the reel end disc 4 pneumatically.
  • the shifting means 13 and the pulling rolls 8 are started and carry the band of reel end discs off the rolls 5 of reel end discs at the same track speed.
  • the pulling rolls 8 stop when the following reel end discs 4 reach their basic positions indicated by their aligning means 9.
