Definitions

  • the invention relates to a band storage device, in particular for sheet metal strips, consisting of a movable loop carriage with at least one deflection roller for a supply loop of the band and of support carriages which have support rollers for the at least one upper loop center and with each other and with the loop carriage through flexible, against one Retractable pull-out tension members are connected.
  • the tension members are formed from chains or ropes, so that when the loop carriage is moved in the sense of a loop formation, the individual support carriages are pulled along by the loop carriage when the chains or ropes stretch between the support carriage and the loop carriage.
  • the high accelerations of the support carriages that occur when tensioning the tension members result in shock-like loads when starting each support carriage, which should be avoided as far as possible.
  • the band is supported unevenly in the area of the upper loop center because the distance between two adjacent support cars is determined either by the tensioned chain or by the support cars pushed together.
  • the invention is therefore based on the object to avoid this effort, so that even when driving the support car via flexible tension members, a bumpless drive of the support car can be ensured from the loop car, while maintaining a uniform distance between the individual support cars.
  • tension members are at least partially elastically extensible, for example as rubber ropes or the like, and are preferably looped around deflection rollers.
  • each tension member can advantageously be looped around deflection pulleys, so that much greater elongation lengths are ensured.
  • the elongation length of the individual tension members corresponds to only a fraction of the travel distance of the loop carriage because all tension members are loaded equally and stretch the same way with the same restoring forces.
  • the support carriages are usually connected to one another on both long sides by tension members.
  • tension members have the disadvantage that if a tension member is torn on one long side, there is a risk that the support carriages concerned will cross because of the then one-sided load.
  • the tension members can engage with their two ends on a support carriage and be guided around at least one deflection roller on the adjacent support carriage.
  • this design always ensures the same tensile stresses on both long sides of the support car.
  • a greater stretch length is ensured without additional loop formation.
  • the pretension of the elastically stretchable tension members can be adjustable, so that the restoring force for the tension members is certainly greater than the driving resistance of the support car train.
  • the preload can be adjusted in a simple manner via a tensioning device for the stretchable tension members.
  • the tape store shown consists essentially of a loop carriage 1 and support carriage 2 which can be moved with the aid of the loop carriage 1 and which are guided on rails 3 with the loop carriage 1.
  • the support carriages 2 have support rollers 4 for the respective upper run 5 of two storage loops 6, which are each guided around a deflection roller 7 of the loop carriage 1. While the lower run 8 of the outer supply loop is supported on stationary rollers 9 in the region of the carriageway 10 carrying the rails 3, the lower run 11 of the inner of the two supply loops 6 rests on support rollers 12 of the support carriage 2.
  • the individual support wagons 2 are connected to one another by tension members 13, the connection of the support wagon 2 directly adjacent to the loop wagon 1 with the loop wagon 1 and the support wagon 2 of the support wagon train facing a fixed drainage point 14 with the fixed drainage point 14 likewise being effected via tension members 13.
  • the tension members 13 are formed by rubber bands or ropes which can be pulled out with respect to their length. The arrangement is such that the tension members 13 engage with their two ends on a support carriage and are guided around deflection rollers 15 of the adjacent support carriage 2.
  • deflection rollers 15 and on the loop carriage 1 are provided at anchor points 14 in order to ensure a corresponding tension member connection between the end support carriage of the support carriage train and the discharge point 14 on the one hand and the loop carriage on the other.
  • the tension members 13 are tensioned at the shortest distance between the support carriages 2, the tension members 13 have to be pulled out against the elastic restoring force when the loop carriage 1 is being moved in the sense of an enlargement of the loop. Since the restoring force of the tension members 13 is selected to be greater than the running resistance of the support car train, all the tension members 13 are pulled out at the same time, which not only ensures a smooth start of the support car 2, but also ensures a uniform distribution of the support car 2 over the loop length. If the loop carriage is moved in the sense of a loop reduction, the support carriages 2 are pulled against one another and against the drain point 14 via the restoring forces of the tension members, so that the support carriages 2 are evenly distributed over the loop length.
  • the tension members 13 can be provided with tensioning devices by means of which the restoring forces are adjusted and coordinated with one another.
  • the tension members In order that corresponding elongation lengths can be achieved for the tension members, the tension members must have a certain minimum length, whereby the length of the tension member determined due to the given smallest distance between the support carriages 2 cannot always be subordinated to the demand for a desired expansion length. In order to remedy this, the tension members 13 according to FIG. 3 in the form of an additional loop 16 are guided back and forth between the deflection rollers 15, so that a sufficient length is achieved in any case with this loop formation.
  • the elastically stretchable tension members 13 could be replaced by inextensible tension members which are wound on spring-loaded storage drums and pulled out of these stores against a corresponding restoring force. It is crucial for a uniform distribution of the support car 2 over the loop length that the tension members can be pulled out evenly against a restoring force, it being immaterial whether these restoring forces are achieved via the elastic expansion behavior of the tension members or via separate return springs.
