Definitions

  • Such a decoiler is e.g. made of steel and iron 103 (1983) No. 7, pages 31 to 36.
  • the decoiler will there with a so-called pre-winding reversing system or coil box used.
  • the object of the present invention is a decoiler to provide an instant start reeling is possible.
  • the object is achieved in that the top frame on his the coil side facing a coil opener for opening the Has federal and that the top frame towards the reel is movable.
  • the decoiler for bundles with different Diameters can be used.
  • a driven pressure lever unit is arranged on the base frame is the upper one via an attachment arranged on the stack frame Pushing the driving roller and the upper straightening roller onto the base frame, the drive for the driven swivel lever unit is particularly suitable be dimensioned small.
  • pressure lever unit should be - preferably pressure and position-controlled hydraulic cylinder units be.
  • the pivot lever units and the pressure lever unit are constructive particularly easy to design if they each have a left and there are swivel or pressure levers on the right of the base frame.
  • the two levers of a lever unit be coupled together, e.g. via a spline or Cross strut to ensure a synchronous movement of the respective pair of levers ensure.
  • the rollers of the roller conveyor are usually driven. This especially applies to the lower driving and straightening roll.
  • the drive for this role is particularly easy to design, if it is driven by an electric motor and the lower drive axle with the electric motor via at least one deflection unit, e.g. a bevel gear or a chain drive.
  • an unwinding station or uncoiler 1 has one Bundling system (or compound winding reversing system) two unwinding rolls 2 on. These carry and turn a coil wound into a bundle 3 Volume 4.
  • the diameter of the collar can be between that of the Federal 3 and that of the federal 3 'vary.
  • the Bundle 3 By turning the Bundle 3, the tape 4 is coiled.
  • a roller conveyor 5 is arranged behind the uncoiler 1.
  • the roller conveyor 5 has a base frame 6 and an attachment frame 7.
  • Base frames are a lower drive and leveling roller 8 and transport rollers 9 arranged.
  • In the top frame 7 are an upper drive roller 10 with an upper drive shaft 11 and an upper straightening roller arranged.
  • the top frame 7 has the uncoiler on it 1 facing side, a collar opener 13 for opening the collar 3.
  • Hydraulic motor 19 actuated.
  • the hydraulic motor 19 operates via a chain drive 20 the collar opener 13 and pivots this way about a pivot axis 21 from its rest position shown in FIG in its operating position shown in Figures 2 and 3.
  • the pivot axis 21 coincides with the upper drive axis 11.
  • the hydraulic motor 19 is pressure controlled and end position controlled.
  • the Hydraulic cylinders 14, 16 are pressure and position controlled.
  • the collar opener 13 is light with the hydraulic cylinder 16 Pressure pivoted against the collar 3 or 3 'to be opened. Then the unwinding rollers 2 are rotated such that the beginning of Band 4 on the pivoted collar opener 13 opens. By further Turning the unwinding rolls 2 then moves the belt 4 under the Bund opener 13 forward and reaches the upper drive roller 10 and upper straightening roller 12. From this point the hydraulic cylinders 16 retracted. At the same time, the collar opener 13 is opened by the Hydraulic motor 19 pivoted back into its rest position. By the retraction of the hydraulic cylinders 16 and the associated Lowering the top frame 7, the band 4 between the drive and Straightening rolls 8, 10, 12 performed. By pivoting the coil opener 13 in its rest position, a loop formation of the Band 4 between the unwinding rollers 2 and the roller conveyor 5 allows.
  • the Hydraulic cylinder 14 extended. Shortly before fully retracting the hydraulic cylinder 16 sets the pressure lever unit 15 on one Approach 22 of the top frame 7 and thereby presses the upper one Driving roller 10 and the upper straightening roller 12 towards the base frame 6. Simultaneously with the placement of the pressure lever unit 15 on the Approach 22, the hydraulic cylinder 16 to an opposite Pressure control reversed, so that it is the pressure by the Counteract pressure lever unit 15.
  • the pressure lever unit 15 and however, the hydraulic cylinders 14 assigned to it are designed in such a way that they exert a greater force on the top frame 7 than the pivot lever unit 17 and the hydraulic cylinders assigned to it 16.
  • the hydraulic cylinders 14 dominate over the Hydraulic cylinder 16. This type of control now ensures connection with the drive of the drive and straightening rollers 8, 10, 12 for the desired Driving and straightening effect.
  • the pivot lever unit 17 consists of a left and to the right of the lower drive and straightening roller 8 arranged swivel lever 23.
  • the pivot levers 23 of the driven pivot lever unit 17 are coupled together by a spline shaft.
  • the pressure lever unit 15 from one left and one on the right of the base frame of the arranged pressure lever 26 exists.
  • the pressure lever 26 also coupled, namely via a cross strut 27.
  • FIG. 4 shows just like the driven one Swivel lever unit 17 one left and right of the lower drive and Straightening roller 8 arranged pivot lever.
