Definitions

  • the invention relates to a support structure for use in a vertical belt storage according to the preamble of claim 1, such a vertical belt storage both according to the preamble of claim 6 and according to the preamble of claim 8, as well as a method for storing a metal strip in a vertical band storage according to the preamble of claim 15.
  • prior art vertical strip accumulators are known.
  • a support frame forming a sling tower is used, in which the metal strip is guided in loops around deflection rollers mounted on upper and lower horizontal roller bridges or traverses whose vertical distance and thus the length of the metal strip stored in the loops can be reduced by vertical movement of at least one the trusses can be changed.
  • Vertical belt stores of the type described also known as a loop tower or looper, are used in belt plants to maintain the continuous process speed during coil handling, ie coil-changing and / or welding the coil start to the belt end.
  • large lengths of tape can be temporarily stored by increasing the loops in which the metal band alternately passes around the upper and lower pulleys of the roller bridges or trusses. This happens, for example, in that when the lower traverse is stationary, the upper traverse in the supporting frame is moved upwards, so that the strip length stored between the roller bridges increases.
  • a vertical tape storage comprising a support structure for a liftable over his in the manner of a pulley and provided with a counterweight storage trolley, which is equipped with pulleys, which deflect in conjunction with fundamental stationary stationary pulleys the incoming and / or outgoing metal strip and to lead.

  • a movable storage cart is guided within this support structure between the two columns, wherein the storage trolley is supported with guides on the inside of the tower or the opposite inner sides of the columns.
  • the counterweights are outside, ie arranged outside the columns.
  • This known steel support structure requires due to the unfavorable force for the carriage guide, the carriage drive and the leadership of the balance weights a relatively heavy and bulky design.
  • a further disadvantage is that the dimensions of the storage wagon, and thus the maximum achievable capacity for this vertical storage, is limited because of the guidance of the storage wagon between the columns.
  • the invention has the object, a support structure for use for a vertical tape storage with simple means cheaper and to provide for such a vertical tape storage a larger tape storage capacity and within it a more precise tape guide.
  • a support structure according to the present invention is formed in the form of a particular vertical column, and is used for a vertical band storage.
  • This support structure comprises at least one double-T-beam, which runs along the longitudinal axis of the support structure and is arranged adjacent to an outer side of the support structure.
  • a guide rail for a traverse of the vertical belt storage is attached to a flange of the double-T-beam.
  • This embodiment of such a supporting structure according to the invention using a double-T-beam is based on the essential knowledge that the double-T-beam forms an essential supporting structural element for the vertical column, and in this case is arranged adjacent to an outer side of the column.
  • a guide rail serves, for example, as a running surface for a traverse of a vertical belt storage, which in a known manner in the vertical direction along the support structure or an associated column is moved back and forth to change the storage capacity of the vertical band memory.

  • These double-T beams are expediently arranged in each case along the longitudinal axis of the supporting structure or of the column, and preferably extend completely along the longitudinal axis of the supporting structure.
  • the individual double-T beams can be connected together by a suitable support structure.
  • the central webs of the individual double-T-beams are each arranged parallel to each other.
  • a vertical band memory serves to store a metal band.
  • the vertical belt storage comprises a support structure with two vertical columns, and a traverse, which is movably guided on the columns in the vertical direction, wherein the traverse is equipped with pulleys, in conjunction with oppositely arranged pulleys facing the incoming and / or expiring metal strip divert and lead.
  • the traverse is guided on the vertical columns such that the lateral ends of the traverse are outside the columns. In other words, the lateral ends of the crossbar protrude beyond the vertical columns to the side.
  • the above-mentioned embodiment of a vertical belt storage according to the invention is based on the essential realization that a total width of the traverse, which is guided on the two vertical columns of the support structure, compared to conventional vertical band storage can be larger, because the lateral ends of the traverse outside the vertical column are located or protrude laterally beyond.
  • the last-mentioned embodiment of the vertical belt store according to the invention can advantageously be further developed in that the supporting structure also has three or more columns which are arranged in line with the two first-mentioned columns.

Between the second and third pillar, a further second traverse is displaceably guided in the vertical direction, the second traverse having deflection rollers which, in interaction with deflection rollers arranged opposite thereto, deflect and guide the incoming and / or outgoing metal strip.
  • the vertical belt storage according to the invention comprises two (or more) trusses which are movably guided between the associated columns in the vertical direction, it is expedient that these traverses run synchronously with one another are. This means that the trusses are guided between the columns so that they always occupy a same horizontal position in comparison to each other. This ensures a uniform storage of metal strip in the vertical band storage.

  • at least one traverse is guided on or between columns in the vertical direction, wherein the traverse is equipped with pulleys, which deflect in conjunction with opposite arranged in particular stationary pulleys, the incoming and / or expiring metal strip and lead.
  • This method is characterized in that a horizontal position of the traverse is continuously detected or monitored, with a possible deviation of the traverse is corrected by the horizontal position automatically. This ensures that the movable in the vertical direction traverse is always exactly horizontal on or between the columns. Said automatic leveling of the horizontal position can also be carried out for a plurality of traverses, which are movably guided between a plurality of columns in the vertical direction.
  • a horizontal position change of a traverse which may possibly be caused by a rope extension due to a rope elongation, can be detected by suitable sensors or displacement sensors, which are mounted or installed, for example, in the area of the columns or on the traverse. These sensors or displacement sensors can also be connected to the control device by signal technology. This makes it possible to compensate for any changes in the traverse with respect to their horizontal position automatically by controlling the servo drives by means of the control device, with the result that the traverse is always exactly horizontally aligned at or between the columns up or down.
  • Distance measuring devices in the form of laser distance sensors can be used for measuring the distance of the traverse - if two such laser distance sensors are installed in the area of the columns of the vertical belt memory, the deviation or the horizontal position change of the traverse can be determined therefrom.
  • it may be provided to mount on the traverse an electronic spirit level, which is suitably connected to a power supply or radio link.
  • the support structure according to one of claims 1 to 5 is expediently used. Compared to the support frames of conventional tape storage hereby a mechanically simple and robust design for the support structure can be achieved, at the same time low production costs.
