Definitions

  • the invention relates to a collar transfer device, in particular for transporting metal coils in a coil box.
  • a coil box is a band reeling device which initially bends the metal strip coming from the roughing train by means of rotationally driven bending rolls, so that it winds up in a winding trough formed by supporting rolls to form a metal collar.
  • the band end becomes the band head of the subsequent finish rolling process. As long as the metal collar is in this winding position, the coil box can not accept another tape.
  • the transfer should be as gentle as possible, otherwise damage to the outer layer of the metal collar may occur if, for example, it strikes hard against a stop.
  • the metal collar which usually has a mass of about 10 to 40 t and a relatively high temperature, from about 900 ° C to 1100 ° C, take damage on its outer turn. A piece on the outer circumference is then scrap.
  • the transfer of the metal collar takes place on carrier rollers, the employment of which is predetermined successively with respect to the transport plane in such a way that a roller table depression advancing in the transport direction is formed.
  • the result is a Bewowungs-sequence that resembles a "wandering wave" and moves the metal collar in a "wave valley”.
  • the metal collar is alternately supported by two or three support rollers. In this case, the federal government is supported in a first fret position by means of two arranged on a first frame part support rollers.
  • the collar is moved out of this position by tilting and lowering this frame part at the same time.
  • a smooth transition to the subsequent in the transport direction roller table is possible.
  • the active transfer between the support by two or three support rollers can be made very gentle by appropriate control of the drives. As a result, only relatively small forces act on the outer circumference of the collar and the risk of damage is lower.
  • a stable position of the waistband can be achieved if the waistband is supported in alternating sequence by two or three idlers during the transfer.
  • FIGS. 1 to 7 illustrated sequence of a collar transfer process explained in more detail.
  • like reference numerals designate the same or similar components.
  • a metal collar 4 can be seen, which is located in a winding position 5 of a coil box, not shown.
  • This coil box is arranged between a roughing mill and a finishing mill of a rolling mill.
  • the coil box is used for winding and unwinding of the belt 2.
  • the coming of the Vorstrasse metal strip 2 may have a temperature of the usual way about 900 - 1100 ° C; the fully wound metal collar 4 usually has a mass of about 10 to 40 t.
  • the metal collar 4 is continuously unwound. In this case, the metal collar 4 rolls in each case with its outer turn at the bottom side arranged ground or support rollers 11, 12, 13, 14, 15 from.
  • the support rollers 11, 12 are arranged on a common frame part 29.
  • the support rollers 13 and 14 each on an associated pivot arm.
  • the two pivot arms point to the winding position 5. They are pivotable by means not shown pivot drives each about an associated axis 27 and 28 respectively.
  • FIG. 1 shows a constellation in which the winding is already completed.
  • the band end 2 of the metal collar 4 is already unwound a bit.
  • the tape head of the tape 2 is already supplied to a driver or a finishing mill, not shown.
  • the method according to the invention provides an approach for a gentle transfer of the metal bundle in the coil box.
  • the collar transfer takes place by coordinated adjustment of the axes of adjacent support rollers 11, 12, 13, 14 whereby a progressing in the transfer direction 8 "wave trough" is formed, which forms a Abwickelmulde 32 for the unwinding collar 4.
  • the two support rollers 11, 12 are mounted on a cross member of a first frame member 29 and rotationally driven.
  • the first frame part 29 consists of a crosspiece and a longitudinal piece.
  • the crosspiece and the longitudinal piece are rigidly interconnected.
  • the longitudinal piece of the first frame part 29 is articulated on the end to a second frame part 30.
  • the first frame part 29 and the second frame part 30 together form the support frame 7.
  • the support frame 7 acts as an angle lever: both the first frame part 29 and the second frame part 30 are each pivotable about an associated pivot axis 25 and 26 (in the drawings of the FIG. 1 to FIG. 7 the drives are omitted for clarity).
  • the two rollers 11 and 12 in two degrees of freedom can be adjusted.
  • a constellation is shown in which the two support rollers 11, 12 form an upwardly open trough by their distance from each other, in which the metal collar 4 is received in a stable position.
  • the support frame 7 is tilted and simultaneously lowered. Like from the FIG. 2 can be seen, this tilting and lowering takes place by the first frame member 29 is pivoted in the direction of arrow 18 about the axis of rotation 25, and at the same time the second frame member in the direction of the arrow 17 is pivoted downwards. Due to the force of gravity and the onset of strip tension 3, the metal collar 4 begins to move in the direction of transfer 8. The support roller 13 limits this movement for now. The metal collar 4 is now again stable in a unwinding trough 32, which with respect to the in FIG. 1 a little further to the left. The three rollers 11, 12 and 13 carry the metal collar 4 in this position. The transition to this position was gentle and without unduly high force on the lateral surface of the Federation. 4
  • the first support roller 13 is now pivoted in the direction of the arrow 19 about the axis 27 down, which again due to gravity, the sideways movement of the metal collar 4 in FIG. 3 is continued until the metal collar 4 gently comes to rest in the unwinding trough 32 formed thereby ( FIG. 3 ). In this position, now support two support rollers the metal collar 4, namely the first support roller 13 and the outlet-side support roller 12 of the support frame. 7
  • FIG. 5 Now shows a scenario after a continuation of this principle.
  • the lateral movement is supported by pivoting up the first carrying roller 13 in the direction of the arrow 23.
  • the first support roller 13 and the second support roller 14 support the metal collar 4 in this constellation (FIG. FIG. 5 ).
  • the Bund 4 is also stable again here.
  • the first support roller 13 and the second support roller 14 are pivoted counterclockwise upwards, whereby the metal collar 4 is raised.
  • the transfer of the metal collar 4 is completed.
  • the metal collar 4 is now in the unwinding position 6.
  • a roller 10 acts at this last movement section as a retaining role or support role and prevents the metal collar 4 due to the rigid arrangement of the support roller 15 rolls too far in the direction of the driver.
  • the support or retaining roller 10 along the double arrow 9 in the horizontal direction is variable.
  • the principle of moving a progressive floor sink has the advantage that the metal collar is constantly in a trough, that is in a stable position.
  • the transfer of the metal collar 4 of support roller to support roller can be done comparatively gently by appropriate employment of the support rollers.
  • each of the rollers 11, 12, 13, 14 is rotationally driven.
  • the peripheral speed is set so that no slip occurs between the speed of the belt 2 and the rotational movement of the roller.
  • the speed of rotation of the roller also takes into account the linear speed component resulting from the pivoting movement of the roller.
