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 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, whereby the discs are attached to the reel ends when the plastic coating on the reel end discs, placed against the reel ends, melts on heating of the press faces of the end presses, whereupon the end presses are shifted apart from each other and the wrapped reel moves away from between the end presses and a new roll is shifted to the position between the end presses for application of the reel end discs.
  • the reel end discs are attached to the ends of the reel to be wrapped by using end presses, but the reel end discs are separate from each other, and they must be fitted onto the press faces of the end presses as well as be aligned in the correct position, for example, manually.
  • the reel end discs are separate discs apart from each other. It is an object of the present invention to make the said inconvenient working step automatic, and this is achieved in an automatic reel wrapping line by, among other things, using reel end discs arranged in the form of a band.
  • 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 are grasped by means of transfer devices and, by means of the transfer devices and 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 the basic positions, the first reel end discs are cut loose from the reel end discs placed in the 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, the transfer devices release their grip and move further to their basic positions.
  • 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 were 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 band of reel end discs is pulled by means of pulling rolls 8 until the aligning means 9 indicate that the first reel end discs 4 are in their basic positions. At that time the pulling rolls 8 stop.
  • the aligning of the reel end discs 4 in the basic position by means of the photocells and light detectors takes place at the corner 11 formed at the edge of the narrow section 10 connecting the reel end discs 4.
  • 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 carrier roll reeler 12 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 roll 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.
  • the reel end discs 4 that were sucked onto the press faces 6 of the end presses 3 are pressed against the ends 2 of the reel 1 to be wrapped.
  • the faces of the reel end discs 4 that are to be placed against the ends 2 of the reel to be wrapped have been coated with a hot-melt agent suitable for the purpose.
  • the press faces 6 of the end presses 3 are heated, whereby the hot-melt layers on the reel end discs 4 melt and the reel end discs 4 adhere to the ends 2 of the reel 1 to be wrapped.
  • the end presses 3 are shifted apart from each other by means of shifting means, and the wrapped reel 1 moves away from between the end presses 3, and a new reel moves to the position between the end presses 3 for the application of the reel end discs 4.
