Definitions

  • connection means compn'ses at least one centering bolt member arranged at the rails of a rail joint, this centering bolt member being displaceable in the direction of the rails and serving to interconnect both rail ends.
  • the present invention relates to a new and improved rail connection arrangement for suspended or overhead conveyors or the like wherein the rail ends are connected with one another by connection members or elements.
  • the track rails are produced by joining together the rail profiles which possess a length determined through their fabrication process.
  • the rail profile typically possesses a travelling flange upon which there is moved with the aid of a suitable drive mechanism the transport unit. Notwithstanding careful laying of the rails it is impossible to prevent non-alignment of the rail ends at a rail joint.
  • the rails are elastically or resiliently suspended at the building or structure in order to prevent the transmission of sound or noises, there cannot be prevented that the travelled (loaded) rail is disposed somewhat lower than the non-travelled or unloaded rail, so that upon crossing from the travelled to the non-travelled rail the travelling carriage or vehicle is subjected to a jolt or impact which is therefore transmitted to the carried load. Consequently, owing to the non-alignment of the ends of the rail flanges, the transport unit and the loads are additionally subjected to impacts.
  • connection means for instance in the form of welded or threaded brackets or plates which are arranged adjacent the actual travelling flange and the remaining components of the rail profile.
  • connection means therefore must be constructed in such a way that they can accommodate the changes in length of the individual rail profiles.
  • Another, more specific object of the present invention relates to an improved rail connection arrangement for suspended or overhead conveyors or the like which can be simply mounted and which does not hinder dismantling and mounting of the rails.
  • Yet a further significant object of the present invention relates to an improved rail connection arrangement for the rails of conveying systems wherein such rail connection arrangement can be easily placed into its rail connecting position and out of such rail connecting position without the use of complicated accessory tools and without requiring a large number of manipulative steps and lengthy and complicated working procedures.
  • inventive rail connection for suspended or overhead conveyors of the present invention is generally manifested by the features that it incorporates at least one centering bolt member arranged at the rails of the rail joint and mounted to be slidable in the direction of the rails and serving to interconnect both rail ends.
  • the centering bolt is arranged in at least one marginal portion of the travelling flange of the rail, this marginal portion possessing a partially open hollow profile and simultaneously forming the travelling track for the travelling rollers of the transportation units. Further, it is advantageous if the centering bolt can be completely displaced into the end region of one of the rails.
  • FIG. 1 is a fragmentary view depicting the rail connection of the present invention for interconnecting two rail ends;
  • FIG. 2 is a sectional view of the rail connection arrangement shown in FIG. 1, taken substantially along the line IIIl thereof.
  • FIG. 1 there are schematically illustrated the adjacent confronting rail ends 10 of two neighboring rail profiles or rails 2, 2, defining therebetween a substantially vertically extending parting plane, and as such for instance are used in suspended or overhead conveyor installations or the like.
  • each such rail for instance looking at the rail profile or rail 2, possesses an actual travelling flange portion 1 at which joins an upstanding web member 2.
  • This web member 2 can be greater in height than shown in FIGS. 1 and 2 and, for instance, can be provided at its upper end with a further flange serving as an attachment flange.
  • the confronting ends 10 of the rail members 2, 2 are arranged from one another at a small spacing 3 serving for compensation of the changes in length of the individual rails 2 and 2'.
  • the rail flange 1 possesses a thickened region 1 1 at the neighborhood of its free marginal end portion 5 and which can serve as the travelling track or surface for both partially illustrated travelling rollers 4 and 4' of a non-depicted transportation unit for carrying a load or the like.
  • a further thickened portion would be arranged symmetrically with respect to the web member 2 and which would then serve for guiding further travelling rollers.
  • the neighboring ends of both rail members 2, 2 are centered by means of a suitable bolt member 6 which extends into recessed or hollow portions 7, 8 of both of the confronting rail ends.
  • the marginal portion 5 forms a hollow profile having a partially circular-shaped cross-sectional configuration.
  • this marginal portion 5 does not define a closed or solid profile, rather the bolt member 6 is not covered towards the outside, as best observed by referring to FIG. 2. Consequently, it is possible to apply to this bolt member 6 a suitable tool in order to drive such bolt member completely into one of the recesses 7 or 8 which possess a suitable length or depth. In this manner it is possible to perform without obstruction the mounting and dismantling operations, so that upon completion thereof the bolt member 6 can again be brought into the position depicted in FIG. 1 in which it serves to center and interconnect both of the rail ends 10.
  • the rail connection of the present invention by means of which the centering bolt member 6 is arranged in the direction of the rails, is not only very simple in construction but also insures for an extremely good alignment of the rail joint since it is arranged in the direct region of the travelling or running track portion of the rail arrangement. Furthermore, when performing assembly and disassembly operations it is possible to easily displace this centering bolt member out of the position shown in FIG. 1 so that it does not get in the way during these operations. Finally, any changes in length of the-rails can be readily compensated without difficulty by this rail connection arrangement of the invention.
  • a rail connection for connecting the confronting ends of adjacent rails of an overhead conveyor system or the like comprising at least one pair of adjacent rails having confronting rail ends, each of said rails incorporating a respective rail traveling flange having a free end equipped with at least one marginal portion providing a rail traveling surface, said confronting ends of adjacent rails forming therebetween a substantially vertically extending parting plane to permit removal of any one given rail without having positionally to alter the next adjacent rail, a single centering bolt means for interconnecting the confronting rail ends with one another arranged at such adjacent rails for sliding movement in the direction of said rails, said single centering bolt means being located at the marginal portion of said flange yet not directly on said traveling surface, at least one of said adjacent rails being equipped with means at the region of its rail end for slidably completely receiving said single centering bolt means, said receiving means comprising a recessed portion provided at s -d rail en 2.
  • a ra i l connec on for connecting the confronting ends of adjacent rails of an overhead conveyor system or the like comprising at least one pair of adjacent rails having confronting rail ends, each of said rails possessing a rail traveling surface, said confronting ends of adjacent rails forming therebetween a substantially vertically extending parting plane to permit removal of any one given rail without having positionally to alter the next adjacent rail, a single centering bolt means for interconnecting the confronting rail ends with one another arranged at such adjacent rails for sliding movement in the direction of said rails, said single centering bolt means being located in the immediate neighborhood of said rail traveling surface yet not directly thereat, at least one of said adjacent rails being equipped with means at the region of its rail end for slidably completely receiving said single centering bolt means, said receiving means comprising a recessed portion provided at said rail end, each of said adjacent rails incorporates a respective rail traveling flange having a free end equipped with at least one marginal portion providing said rail traveling surface, said marginal portion forming a profile member
