Definitions

  • the invention relates to a supporting roller arrangement for a rack, particularly a large-capacity rack.
  • the repeated overloading of an individual roller can also arise from the fact that a foreign body, for example a paper carton or the contents of a carton, can roll in between the roller track and the roller, whereby the individual roller is destroyed.
  • a foreign body for example a paper carton or the contents of a carton
  • the object of the invention avoids the high point-loadings as a consequence of local unevennesses in the substructure of a rack, which are unavoidable with a welded construction, by making the supporting rollers adapt themselves resiliently to these unevennesses. Equal loads are then achieved even if the foundation subsides locally.
  • a relatively flexible, flat faced hollow member or a fiat bar is adjustable in height, lying on cemented-in screwbolts which form stilts.
  • This adjustable track lie springmembers, which support the individual jack-rollers. These spring-members are pretensioned to about two-thirds their normal carrying capacity, so that at their normal carrying capacity the spring-members are further compressed. At those points where the roller track falls below the specified level, the spring-member can expand itself to its pretensioned position, so that the roller thereafter carries about two-thirds of the normal force. The missing third then distributes itself over the rollers in the vicinity.
  • the spring-member can be made in any desired manner, as for example from leafor cup-springs or even, as shown below, from a rubber Which presses itself elastically into the hollow spaces of a perforated sheet or a corrugated sheet.
  • the spring-member has not only the task of loadequalization, but also, in particular, the task of adapting the roller-axle for the purpose of even loadings with variably inclined roller conveyor tracks, so as thereby to attain an even line-contact for the protection of ball-bearings supporting the roller, the roller circumference itself and the roller track.
  • the object of the invention does away with this lateral drift by means of the fact that the rollers are partially released at the junction between two neighbouring racks, due to the chamfered junctions, so that the jack-roller moves off sideways with its substructure so that any amount of drift, which arises from maladjustment and from the related roller track length from junction to junction, springs back to the original position at the junction.
  • the drift of different neighbouring racks is not additive, so that the amounts of drift and the necessary external guiding forces are kept within acceptable limits.
  • FIGURE 1 shows an example according to the invention in cross section.
  • FIGURE 2 shows the roller body in plan view.
  • FIGURE 3 shows roller conveyor tracks with skids.
  • the adjusting nuts 3 carry a flat bar or a sufficiently elastic hollow, flat member 4.
  • a spring-member consisting, for example, of rubber strips 5, 6, and the perforated sheet 7 and/or the ribs 8 of a corrugated sheet 9, on which are mounted the end-plates 10 of the roller axle 11.
  • the roller 12 flexibly supports the roller track of the rack-substructure.
  • the adjustment and pre-compression is effected with nuts 3 and/or 14.
  • the sidebar 15 secures the roller axle.
  • FIGURE 3 shows roller conveyor tracks with chamfered edges 16 and cup-springs 17 as spring-members.
  • the rollers 12 between the chamfers 16 can relieve the tension at the rack junction points in relation to the lateral elasticity which arises from the drift, in order to prevent the roller from sliding during lateral drift with line contact.
  • the lateral drift is unavoidable.
  • it is absorbed by the elasticity of the stem of the screw-bolt 2 having the free bend-length 20, and partially also by the spring-member 17 for the roller conveyor track section in question, and discharged at the chamfer point 16 where the roller is relieved of its load.
  • the loaded spring-member height is indicated by 21.
  • a supporting roller arrangement for transportable, movable racks comprising rollers and elastic supporting means, including compressed spring supports for the rollers for equalising the load: the improvement of stiltlike supports for the said com-pressed spring supports, the said stilt-like supports being threaded and carrying nuts acting an adjusting members for the height and spring compression of the compressed spring supports.
  • the compressed spring supports comprise a flat member freely mounted and adjustable for height on the stilt-like supports by means of one of the said nuts in each stilt-like support, a compressed spring supported in the fiat memher, and a spring compressing member freely mounted in the stilt-like supports and adjustable therein by one of the said nuts thcreabove in each of the stilt-like supports.
