Definitions

  • the invention relates to a vertical belt store for bridging interruptions in the belt run in continuous belt systems, such as continuous annealing lines or the like, consisting of a support frame forming a loop tower, in which the belt is guided in loops around deflection rollers mounted on upper and lower horizontal roller bridges, their vertical spacing and thus the length of the tape stored in the loops can be changed by moving one of the roller bridges vertically, the dead weight of the mobile roller bridge being compensated for by counterweights.
  • continuous belt systems such as continuous annealing lines or the like
  • Vertical belt stores of the type described which are also known as loop towers or loopers, are used in belt systems to maintain the continuous process speed during coil handling, ie when changing the coil and / or welding the beginning of the coil to the end of the belt.
  • Large lengths of tape can be temporarily stored in them by increasing the loops in which the tape is guided alternately around the upper and lower deflection rollers of the roller bridges. This is done, for example, by moving the upper roller bridge upward in the supporting frame when the lower roller bridge is stationary, so that the length of the strip stored between the roller bridges increases.
  • counterweights on the side outside the supporting frame to be arranged, which are connected to the movable roller bridge by means of ropes or chains and compensate for their own weight.
  • the known construction has disadvantages, which can be seen in particular in the unusually high outlay and the material costs for the weight compensation of the movable roller bridge.
  • threading the tape after a tape tear which is sometimes unavoidable in such systems, is very time-consuming and personnel-intensive, since the beginning of the tape of the tape to be threaded must be laboriously threaded around the upper and lower deflection rollers of the roller bridges moved next to each other.
  • the weight compensation is very costly simply because the enormous weights of the roller bridge have to be balanced and the material value for the counterweights alone is considerable.
  • there are the deflection devices in connection with the counterweight suspensions which make the entire system more expensive.
  • the two roller bridges in the support frame are guided in synchronism towards and away from one another and the dead weight of one roller bridge serving as counterweight compensates for the dead weight of the other roller bridge.
  • the one roller bridge is articulated on the upward run and the other roller bridge is articulated on the downward run of common, vertically deflected cable or chain drives driven at the same speed, the deflection rollers of which are mounted in the upper region of the supporting frame.
  • the chains or ropes ensure synchronism of the upper and lower roller bridge and are easily synchronously drivable, for example if, according to a further feature of the invention, in the case of chain drives the deflection rollers are designed as pinions which can be synchronously driven in the chains.
  • the cable or chain drives are endlessly guided around the deflection rollers in the upper area of the support frame and deflection rollers in the lower area of the support frame.
  • the drive can take place from a common drive motor via transfer case.
  • a particularly favorable embodiment of the invention is characterized in that the roller bridges for threading the band into the middle of the supporting frame can be moved into a position in which the upper and lower deflection rollers for the band alternately reach behind each other so comb-like that between the upper and the lower guide rollers remain a passage for a band to be threaded horizontally, on the lower side of which the guide rollers of the upper and on the upper side the guide rollers of the lower roller bridge are arranged. That way it can Belt is pushed horizontally between the upper and lower pulleys, a procedure that can be carried out semi-automatically. After threading the tape, the upper and lower deflection rollers are positioned so that the loops are automatically formed when the roller bridges move apart.
  • Shortening the threading times after tape breaks means a significant reduction in production downtime and thus an increase in production volume due to the higher availability of the system.
  • the present invention offers a solution by simplifying the construction of the vertical belt store, which on the one hand enables significant cost savings in the manufacture of the system and increases the cost-effectiveness of the system by reducing idle time in production.
  • roller bridges are self-propelled, drive elements engaging on both sides of the roller bridge in a form-fitting manner being provided, which are fed by a drive traveling on the roller bridge.
  • the drive takes place, for example, via moving drive units, which engage pinions in toothed racks arranged vertically on both sides of the supporting frame and move the respective roller bridge.
  • Spindle or drive shaft drives are also possible.
  • the travel speed of both roller bridges is synchronized, if necessary by an electrical shaft. It is also possible to provide only the lower roller bridge with a corresponding drive unit, while the upper roller bridge is tracked via the rope or the chain.
  • FIG. 2 the support frame of a vertical belt store according to the prior art, designated 1, is shown roughly schematically.
  • An upper roller bridge 3 can be moved up and down in the vertical direction in the support frame 1 on rollers 2.
  • the band denoted by 6 is guided over the deflection rollers 5, which stand at 4 and project downwards.
  • a second roller bridge 7 is fixedly arranged in the lower part of the support frame 1 and supports, also elevated at 4, the upwardly directed lower deflection rollers 8 for the belt 6, which are alternately diverted around the upper deflection rollers 5 and the lower deflection rollers 8 in loops within of the supporting structure 1 is guided.
  • the upper roller bridge 3 is driven by endless cable or chain drives 13 which are guided in the upper region of the supporting structure 1 via deflecting rollers 14 and in the lower region of the supporting structure via lower deflecting rollers 15, 16 and 17.
  • the upper roller bridge 3 is articulated at 23, counterweights 12 being provided for their own weight compensation, which are also suspended on a chain or a rope 9, which are guided around deflection rollers 11 on the support frame 1 and at 10 on the Roller bridge 3 are attached.
  • the sum of the two counterweights 12 corresponds to the dead weight of the roller bridge 3, so that the cable or chain drives 13 only have to overcome the frictional forces from the loops in which the belt is guided.
  • the vertical tape storage according to the invention is shown, which is significantly simplified compared to the prior art.
  • the support frame is designated 1, in which the band 6 is guided in loops over the upper deflection rollers 5 and the lower deflection rollers 8.
  • the lower roller bridge 7 can also be moved on rollers 2 in the supporting frame 1, namely in synchronism with the upper roller bridge 3.
  • an endlessly circulating cable or chain drive 13 is guided in a vertical direction on each side of the roller bridges 3, 7, the cable or chain drives 13 being guided over the deflection rollers 14 and 15.
  • the lower deflection rollers 15 are connected to gears 18, which are fed by the common drive motor 19 and drive the deflection rollers 15 with changing directions of rotation.
  • the lower roller bridge is articulated to the inner strand of the cable or chain drive 13.
  • the cable or chain drive 13 is driven via the deflection wheels 15, it is ensured that the movements of the roller bridges 3 and 7 take place synchronously, but in opposite directions, the counterbalancing provided at the same time no longer requiring counterweights.
  • FIG. 3 shows how the threading-in process of a new beginning of the tape takes place with the tape store according to the invention.
  • the upper and lower roller bridges 3 and 7 are moved so far into the center of the supporting frame 1 that the upper supporting rollers 5 are positioned laterally below the lower supporting rollers 8.
  • a horizontal passage for the belt 6 is created in the center plane between the upper 5 and lower support rollers 8, which is guided over the deflection rollers 21 and 22 fixed to the support frame 1 and can also be introduced partially automatically.
  • the belt is guided into the desired loops.
  • the tedious threading of a torn band around the upper and lower deflection rollers in conventional systems is greatly simplified by the invention.
  • FIG. 4 shows a variant of the vertical belt store according to the invention, in which no endless cable or chain drive 13 is used for balancing the roller bridges 3, 7, but rather a rope or a chain 24 attached to each of the roller bridges at 28.
  • the rope or chain 24, as in the other solutions, is guided over a deflection roller 14 mounted at the top in the support frame 1, so that the roller bridges 3, 7 are in equilibrium with appropriate dead weights.
  • the drive takes place, for example, via moving drive units 25, which engage with pinions 26 in racks 27 arranged vertically on both sides of the supporting frame 1 and move the respective roller bridge 3, 7.
  • the travel speed of both roller bridges 3, 7 is synchronized, if necessary by an electronic shaft. It is also possible to provide only the lower roller bridge 7 with a corresponding drive unit 25, while the upper roller bridge 3 is tracked via the rope or the chain 24.
  • the alternative solution has the particular advantage that if the upper guide rollers 14 are in turn mounted vertically lowerable in the support frame, for example on a hoist 29 of a crane, then by lowering the guide rollers 14 when roller bridges 3, 7 existing sets can be moved to a position in the scaffolding 1, in which the beginning of the tape can be threaded into the passline of the system.
  • FIG. 5 the same parts being labeled the same.
  • the roller bridges are lowered synchronously by both hoists 29, as a result of which the roller bridges 3, 7 are brought into the desired threading position.
  • the pass line of the system is first left by lifting the deflection rollers 14 via the lifting mechanisms 29, i. H. both roller bridges 3, 7 are raised to the middle position in the support frame 1 and moved apart in the manner described above, so that the belt store is ready for use with the formation of loops.
