Definitions

  • the invention relates to a strip storage for a continuous operation of rolling mills, in particular a loop-forming strip storage for sheet metal strips in strip processing systems, consisting of a sling carriage that can be moved on guides in the sense of a sling change with at least one deflection roller for a sling and with the sling carriage by tension members such as ropes, chains or The like connected, with at least one support roller for the tape also movable on guides, as well as with at least one feed roller and a discharge roller for the tape.
  • Strip storage for rolled strips is required in order to be able to operate the rolling stands in rolling mills continuously, even if individual bundles which have to be connected to one another before being introduced into the rolling stand are to be fed to the rolling mill or rolling stand and rolled by the latter.
  • a loop storage device and a loop former of some form must be provided which have a capacity is designed in such a way that the strip can also be fed continuously to the roll stand or rolling mill when the individual bundles are prepared or welded to one another.
  • pickling plants or annealing furnaces that are operated continuously and in which the different incoming strip speeds have to be compensated for.
  • sling towers sling pits or horizontal sling pullers are used.
  • Horizontal loop pullers or horizontally arranged tape storage devices are known from the prior art, in particular from DE-OS 1 953 169, AT-PS 299 103 and from European patent application 0 110 864.
  • the horizontal loop puller according to DE-OS 1 953 169 for tape processing systems with loop carriage and idlers is characterized in that the idlers are mounted in several so-called followers that are movable in the horizontal direction.
  • the ropes connecting the trailer and the sling carriage are wound on rope drums and are kept constantly tensioned by the drive of the rope drums. Since the sling carriage pushes the follower in front of it in the sense of shortening the storage sling, the restoring force via the cable drum drives only has the task of keeping the connecting cables taut so that the following sliders are only moved by the loop carriage when the rope length between the sling wagon and the following successor is used up. If the cable drum is driven by a spring drum, the springs only have a short service life of a few months. Is the cable drum driven? electrical, each motor must have its own control and its own energy supply. Both are disadvantageous.
  • the horizontal strip store for sheet metal strips according to AT-PS 299 103 contains a movable loop carriage, which can preferably be driven with a constant torque in the sense of an enlarged loop, and several support carriages which can be moved along guide rails.
  • An endless rope, which is guided around pulleys, is connected to the sling carriage and the support carriage. From this rope, the drive for the support car is derived via take-off rollers with the interposition of reduction gears in such a way that the support cars are at the same distance from one another when the sling car moves.
  • a particular disadvantage of this tape storage device can be seen in the fact that a different transmission ratio is necessary for each carriage and that a high risk of contamination of the drive pinion and the rack does not lead to exact drive and transmission ratios.
  • the horizontal belt store according to EP-OS 0 110 864 also shows a movable loop carriage to which individual support carriages are coupled with the aid of flexible tension members which can be pulled out against a restoring force.
  • These tension members should be elastically stretchable at least in some areas. They are designed, for example, as rubber ropes or the like and are looped around deflection rollers. This training is intended to effect a bumpless drive of the support car from the loop car while maintaining a uniform distance between the individual support cars.
  • a disadvantage of this band storage device is that the flexible or elastic rubber ropes age relatively quickly and become brittle and therefore wear out uncontrollably and at different speeds can and that rubber ropes in the rough rolling mill environment can be easily damaged, so that there is also a risk of tearing the rubber ropes.
  • the tape storage of the type mentioned is characterized by a arranged at least on each support carriage with a torque resistor cooperating cam drum, on the drum shell as a tension member runs a traction rope, the torque resistor is a torque motor with constant torque.
  • the advantages of the band storage device according to the invention are that both when filling and when emptying the storage device, the sheet metal strip is carried optimally and continuously by support rollers of the support car, that no jolting load is transferred to the support car when moving the sling car, and that the use of heavy-duty steel cables is the arrangement of the cam drum and the preferred use of a torque motor lead to a very high reliability of the system.
  • the torque motor can be designed to be relatively small, since it only has to overcome the frictional moments. Even when the sling carriage is moved back, the support carriages keep the same as one another due to the inventive measures Distances.
  • the combination of a torque motor and a cam drum achieves a cable pull that is directly proportional to the cable length.
  • the further embodiment of the invention shows a cam drum with an increasing contour, on which the tension member is wound or unwound during a process of the loop carriage.
  • a contour preferably a conical drum
  • the cam drum consists of a short cylindrical section with a subsequently rising drum contour.
  • the conical part of the drum should preferably have a diameter ratio of 1: 3 to 1: 3.5.
  • the cone-shaped drum contour has helically screwed-in cable grooves, so that an exact guidance of the traction cable on the cone is ensured, as a result of which the predetermined distances between the support carriages are ensured during the process. It is useful here if the drum contour is surrounded by a suitably designed hood at a distance, the traction cable running between the drum contour and the hood. Exact cable guidance on the cam drum can also be achieved in that the cam drum is gearingly connected to a guide device for the traction cable to be guided on the drum contour. Rope displacements, rope entanglements or a rope running over one another on the cam drum are avoided with great certainty. When using heavy-duty steel cables as tension members, the measures described above enable the support carriages to be spaced precisely and very reliably with each other, so that the strip storage works robustly and maintenance-free even in the most difficult operating conditions in the rolling mill.
  • the torque motor and the cam drum connected to it are arranged in the area of the subframe of the support carriage, preferably at the level of the wheel axles of the support carriage, the torque motor making electrical contact with a current-carrying rail arranged in the foundation and between the wheel guides or with a cable garland Has.
  • the cam drum and the torque motor are expediently to be arranged in the middle of the axis, so that the lowest possible lateral forces during the movement act on the support carriages.
  • the band store 1 consists of a loop carriage 2 which is moved on rails 4 by a motor-driven winch 3.
  • the sling carriage 2 carries a deflection roller 5.
  • a feed roller 6 or a discharge roller 7 for the sheet metal strip 8 to be stored is provided at the entrance or exit of the strip store.
  • the support car 9 have wheels 14 which run on the rails 4.
  • a cam drum 15 with a torque motor 16 is arranged in the area of the subframe 29 of each support carriage 9, the torque motor being in contact with a busbar 17 which is arranged between the guide rails 4 in the foundation 18.
  • the torque motor 16 can also receive the power supply via a cable garland, not shown.
  • the cam drum 15 connected to the torque motor 16 - the exemplary embodiment according to FIG. 3 shows a cone 21 - has cable grooves 19 in which a traction cable 20 runs, which forms the connection between loop car 2 and support car 9 and between the support car 9 with one another .
  • the cam drum consists of a short cylindrical drum section 22 with the cone 21 which then rises.
  • the cable grooves 19 are screwed into the cone 21 in a helical manner.
  • the cone is surrounded by a suitably designed hood 24 at a distance, the traction cable 20 running between the cone and hood.
  • the cam drum can be connected in a geared manner with the aid of a toothing 25 and a pinion 26 with a helically grooved pinion shaft 27 to a guide device 28 for the pull rope 20 in order to guide the pull rope on the cone 21 as precisely as possible. This can be done, for example, by providing the guide device 28 with an inner groove corresponding to the pinion shaft 27, so that the guide device is displaced by predetermined paths when the cam drum rotates or when the pinion shaft 27 rotates becomes.
  • the storage of the cam drum and pinion shaft can be carried out by means customary in practice and is not shown for the sake of simplicity.
  • the support carriages 9 and the loop carriage 2 are moved together in the area of the feed roller 6 and the discharge roller 7, respectively.
  • the connecting pull rope 20 is completely wound on the cone 21 for each individual support carriage.
  • the motor-driven winch 3 pulls the sling car 2 against the braking torque of the torque motors 16 onto the winch.
  • the traction cable 20 is unwound from each cam drum by certain amounts which correspond to the travel path of the individual support carriages 9. Since the torque motors 16 are designed in the same way for all support carriages, all support carriages 9 are pulled out against the same braking torque, so that large distances between the support carriages 9 form with respect to the respective travel point of the loop carriage. A cable length-dependent cable pull is therefore achieved.
  • the sling wagon 2 is moved back, whereby the connecting cable between the sling wagon 2 and the support wagon 9 is relieved.
  • the relaxed and shortening pull rope 20 is wound onto the drum contour 23 by amounts by which the distance between the loop carriage 2 and the support carriage 9 decreases.
  • the relief of the traction cable between the sling car and the support car likewise leads to a relief of the connecting traction cable between each support car 9.
  • the relieved and shortening traction cables between the support cars from the individual curve drums In this way, the same distance is always set between the loop carriage 2 and the next support car 9 and between the support car 9 when the tape store is emptied, depending on the respective position of the loop car.
