Definitions

  • the invention relates to a band storage machine for the intermediate storage of band-shaped material in continuously operated processing lines, for example when feeding band plates to pipe welding machines, with two concentrically arranged roller baskets for winding the band and removing the band via a lateral offset guide arranged in the inner basket.
  • Tape stores serve the purpose of allowing the next tape to be steadily attached to the end of the previous tape without stopping the processing line.
  • this involves welding a new coil to the end edge of a coil being processed, e.g. B. in the manufacture of longitudinally welded pipes.
  • the preparation of the strip ends and the welding of a new coil takes about 2 - 4 minutes, during which the joint and welding point must not move significantly.
  • Older known tape storage devices are designed as a loop pit, loop scaffold or loop carriage, which among other things has the disadvantage of requiring a large amount of space.
  • a tape storage device with a lying tape guide, i. H. the tape rests on a long edge in the memory.
  • the storage device has the shape of a standing cylinder, in which the band forms a spiral.
  • a so-called driver is provided for transporting the belt, which feeds the belt in a sliding manner into the cylinder.
  • This requires a corresponding stiffness of the strip material, so that there are limits to the strip thickness downwards.
  • the band edge lying on it is often damaged and that relative movements take place between the individual band windings.
  • a number of disadvantages of the aforementioned known tape storage devices are avoided by a tape storage machine which has become known as a free loop tape storage device.
  • This type has the generic features mentioned at the outset, namely two concentrically arranged roller baskets, which in the known machine are fixedly arranged around a horizontal central axis, so that it is a lying drum which does not move itself.
  • the tape is pushed into the memory by a driver, first on the inside of the outer roller basket, where it forms a tape roll that grows outwards.
  • the belt merges freely via one running ribbon loop to the outside of the inner roller basket and also forms a ribbon roll there.
  • the belt leaves the store via the lateral offset guide arranged in the inner basket and runs from there to the processing machine.
  • This known type of tape storage has a comparatively large storage capacity in relation to its space requirement.
  • the sliding feeding of the tape into the memory is and remains a disadvantage, so that with certain tape data it is not possible to avoid the tape breaking out or being compressed laterally.
  • the invention has for its object to provide a tape storage machine of the type specified, in which the tape is transported by pulling and is treated particularly gently on the whole.
  • the advantage of a large storage capacity in a small space should be retained.
  • the invention has the advantage that the tape during the time in which storage is not required because the end of the coil is not yet present, with the exception of the necessary lateral offset guidance can run in a straight line by crossing the two roller baskets in the so-called bypass. This is associated with a very important protection of the tape, which is reflected in the quality of the product made from the tape. It is equivalent to the fact that the tape is only pulled through the memory, both in the bypass mode and in the memory mode. As a result, the strip material is also stressed considerably less than in the known storage devices. In addition, this type of treatment can also process tapes with critical data, which has not previously been the case to the same extent. This is a consequence of the rotating outer roller basket acting as an active loading basket. The effort for a driver corresponding to the known free loop tape storage is eliminated.
  • a strip storage machine 10 which is connected to a strip steel processing line, the other components of which are not shown in the drawing, is set up on a factory floor 11 and works in the drawing in the direction of the arrow 12 from left to right.
  • an unwinding device 13 for steel strip coils 14 from which a strip 15 to be processed is drawn off, passed through the machine 10 and transported according to arrow 12 to the next station of the processing line.
  • the strip 15 reaches beyond the arrow 12 to a pulling device, not shown, which provides the tensile force for transporting the strip 15 through the strip storage machine 10.
  • the machine 10 has a base frame 16 on which two roller baskets are mounted, namely an outer or loading basket 17 and an inner basket 18. While the inner basket 18 is stationary, i. H. is arranged non-rotatably, the outer basket 17 can rotate about the inner basket 18 by being rotatably mounted accordingly.
  • the common center axis of both baskets 17, 18 runs horizontally, which results in an upright arrangement of the tape store and the tape 15 is guided lying flat.
  • the roller baskets consist of circular base plates and rollers attached to them at right angles along a circular line, which run on corresponding axle bolts.
  • the outer basket 17 has an annular base plate 19 which encloses a circular disk-shaped base plate 20 of the inner basket 18 with its central opening. Both base plates 19, 20 are arranged in alignment with one another.
  • the base plate 19 of the outer or loading basket 17 carries a ring of, for example, twenty-four support rollers 21, of which only eleven are shown in the drawing for the sake of simplicity, and also a loading roller 22 which has a larger diameter than the support rollers 21.
  • the base plate 20 of the inner basket 18 is equipped with, for example, thirteen (here seven) support rollers 23 and a support and deflection roller 24, the latter taking a fixed position, which will be explained later.
  • a side offset guide 25 in the form of an obliquely to the center axis of the roller baskets 17, 18 in the direction of the arrow 12 towards the pin of a comparatively large diameter, around which the band 15 is looped once, so that it is displaced towards the open side of the roller baskets (FIG. 2), to such an extent that the band 15 emerges from the ring of rollers 21, 23.
  • a cross cutting and welding machine 31 is set up in front of the machine 10 for the production of the belt connection, and an auxiliary roller 26 with a belt stopper 27 is arranged on the machine 10, between which the tape runs through.
  • Such an auxiliary roller can also be provided on the opposite side of the outer basket 17, but this is not necessary in the exemplary embodiment shown in the drawing.
  • an electric motor (not shown) is provided, which is located on the rear of the machine 10 and is controlled in a manner to be described.
  • the rollers 21, 22, 23, 24 and 26 are as such not driven, but rotate under the action of the belt 15 running over them.
  • the lateral offset guide 25 also does not have its own drive. Finally, this also applies to the unwinding device 13 with coil 14.
  • each roller of these baskets can move to a certain extent along a radial line on the relevant base plate 19, 20 , so that the increasing diameter of the tape wraps on the reel baskets are taken into account appropriately.
  • the spreading of the rolls can be carried out, for example, by means of pneumatic devices, the rolls 21, 22, 23, 24 corresponding to the increasing inside diameter of the tape roll.
  • the wall thickness of the strip sheets to be processed is usually above 0.2 mm. In the case of a pipe mill, speeds of between 25 and 180 m / min are used depending on the sheet thickness. The speed of feeding the tape into the tape storage device can currently reach 500 m / min. Up to about 1,000 m of tape can be accommodated in a tape storage device of the present type. 4th
  • FIG. 1 represents the ready position of the tape store. In this position, the tape 15 is pulled off the coil 14 practically directly from the coil 14 without the roller baskets 17, 18 functioning; the tape 15 is simply pulled through the machine 10. This ensures maximum protection of the belt and storage machine as well as a corresponding energy saving.
  • the loading basket 17 is rotated, namely counterclockwise as shown in FIG. 1, whereupon the store is loaded with tape supply.
  • the loading roller 22 lies from above on the belt 15 and pulls it down between the auxiliary roller 26 and the support and deflection roller 24 (see FIG. 4) and to the left in a circle both on the outside of the support rollers 21 of the outer or loading basket 17 as well as on the outside of the support rollers 23 of the inner basket 18 along, so that with several revolutions of the loading basket 17 with loading roller 22, a band wrap 28, 29 forms on both baskets, the number of band layers in the two windings always being the same and - Which is an important advantage - there is no relative movement between the individual belt layers.
  • the tape 15 is removed from the storage device in the direction of the arrow 12 via the support and deflection roller 24 from the inside of the tape roll 29, which is located on the inner basket 18. Since the loading basket 17 continuously winds up further layers of tape from the outside onto the inner tape roll 29 via the loading roll 22, the outside diameter of this roll increases continuously. The internal diameter of the winding 29, which also increases due to the continued strip removal in the direction of the arrow 12, is compensated for by the pneumatic spreading of the support rollers 23 of the inner basket 18 already mentioned.
  • the diameter of the outer tape roll 28, which is located on the support rollers 21 of the outer basket 17, also increases, because the layers applied to the inner tape roll 29 from the outside by the loading roller 22 are removed from the inside of the tape roll 28 of the loading basket 17, whereas Additional tape layers can be applied from the coil 14 to the outside of the tape roll 28 via the auxiliary roller 26.
  • the support rollers 21 and the loading roller 22 can also be pneumatically expanded. .
  • the propulsion begins of the loading basket 17 is switched off automatically, ie the storage has now reached its highest filling level.
  • the stopper 27 is activated and holds the rest of the strip 15 coming in from the now empty coil 14 so that the beginning of the next coil can be welded on.
  • the unwinding device 13 is conventionally set up in such a way that it keeps the new coil ready when the old strip is nearing its end.
  • a new coil 30 is arranged in FIG.
  • the new coil 30 has different values, in particular different thickness and different inside diameter of the coil, only the setting values for the storage connection, for the propulsion and braking moments of the loading basket 17 and for the spreading pressures of the rollers of the roller baskets 17, 18 need to be changed , which can easily be done using the table already mentioned. If the bandwidth also changes, the side guide rollers (not shown in the drawing) must also be adjusted in a conventional manner. The time required for a complete changeover is still only about ten minutes.
  • the L adekorb tape storage machine 10 may compared with the representation in Figures 1 - 3 are carried out with the reverse working direction, the tape transport to the processing machine that is from right to left, so that the rotating load basket 17 during the filling of the memory rotates counterclockwise.
  • the directional arrows at the three positions of the loading roller 22 indicate the direction in which the loading basket 17 rotates with the loading roller 22 in the respective phase of the memory game.
