Definitions

  • a widely used handling system for its good stepped slope travel characteristics is the one in which the idling trucks, or hangers, are made to run while suspended from a rail by means of a powered tow chain.
  • Said systems are relatively easy to provide, low in cost, and allow the use of the conveyance line even in environments containing potentially corrosive or explosive mixtures such as for example in paint lines or environments with relatively high temperatures as with foundry conveyance.
  • chain systems have problems of high noise and low conveyance speed, generally less than 5m per minute.
  • This embodiment suffers from problems generated by the use of a chain system as the conveyance line on which the powered trucks are run.
  • the rail of the load is provided with two facing C section bars between which run both the idling truck wheels and the powered tractive truck wheels.
  • the section bars are supported at the ends by horse-shoe arms arranged surrounding a passage for the chain-sliding rail.
  • This arrangement keeps the height occupied relatively low but is severely penalised for entry and exit of the tractive trucks at the beginning and end of the section bars where they are used. In addition, it is difficult to disassemble a tractor from the line in case of failure.
  • the general purpose of the present invention is to obviate the above mentioned shortcomings by supplying an suspended conveyance system which would provide, with limited cost and encumbrance, optimal conveyance flexibility characteristics together with high speed and low noise.
  • a conveyance system with suspended supporting rail on which run a plurality of idling trucks for load conveyance, each idling truck being attachable to a powered tractive truck running on said supporting rail and characterised in that the supporting rail has a cross section generally in the shape of the letter I, the idling trucks have running wheels arranged in contact with the upper surface of the I, and each of the tractive trucks has a drive wheel arranged in contact with the upper surface of the supporting rail and thrust rollers in contact with the lower surface of the supporting rail, at least one of the thrust rollers being thrust elastically against the supporting rail with thrust means operated by the hooking of the idling truck to the tractor.
  • fig. 1 shows a powered truck provided in accordance with the present invention and indicated generally by reference number 10.
  • Said truck comprises a powered or tractive part 11 and a load supporting bar or hanger 12, both running on an I-shaped supporting rail 15.
  • the load supporting part comprises an idling truck with rollers or wheels 13, 14 running on top of the rail and supporting a platform 16 to which is hung the load 19, e.g. an automobile body, by means of supports 17, 18.
  • the load truck comprises also side rollers 28 for guidance along the side ribs of the rail.
  • the tractor 11 comprises a frame 20 which rests above on the rail by means of a wheel 21 powered by a motor 22.
  • Side guide rollers 23 ensure guidance of the tractor along the rail for support on its side edges.
  • the frame 20 supports also thrust rollers 24, 25 arranged against the lower surface of the rail.
  • the front roller 25 has its own pin 27 sliding vertically in a support 29 containing a thrust spring 26 for the roller against the rail.
  • Connecting means comprise a rocker arm 30 pivoted at 31 to the tractor frame and bearing at the rear a hooking tooth 32 for a pawl 33 pivoted at 34 to the front part of the hanger.
  • the front part of the hanger 12 supports also an idling caster 34 for running on a handling arm 36 of the hanger, projecting beyond the tooth 32.
  • the pawl 33 has a free end folded downward and is freely moving between the horizontal position shown in solid lines and the inclined position shown in broken lines.
  • the tooth 32 has a flat inclined surface 37 so that, as the hanger draws near the tractor, the free end of the pawl runs on the inclined plane 37 and engages with the tooth 32 as shown in fig. 3. Simultaneously the caster 35 runs along the arm 36, pushing it downward.
  • the rocker arm 30 rotates thus around the pivot 31 and with its opposite end 38, supporting a running roller 39, further loads the thrust spring 26 of the roller 25 against the rail.
  • Fig. 4 shows a rear view of the tractor along plane of cut IV-IV of fig. 2.
  • I shape of the rail and a C-shaped arm 40 connected laterally to the web of the rail and supporting said rail from the ceiling.
  • the pawl 33 has a release rod 41 operated for example through cams 42 arranged along the path.
  • the free end of the rod is raised by a cam 42, the pawl rises beyond the tooth 32 and the truck is separated from the tractor.
  • the supports 40 of the rail 15 can also support an auxiliary rail 43 on which run trucks 44 supporting below a powered chain 45.
  • the chain 45 has below at appropriately spaced intervals fingers 46 for engagement in striker means or elements 47.
  • the engagement means comprise two arms 48, 49 inclined toward each other and pivoted to arrange themselves due to their dead weight in the position shown in the figures also being capable of lowering for rotation around their own pivot. In this manner, the arms can be lowered upon running on their upper surface of a finger 46 to insert itself between their facing ends.
  • the front arm 48 constitutes a striker for the finger of the chain, which then tows the truck.
  • the rear arm 49 simultaneously prevents the truck from moving forward due to inertia and withdrawing from the finger.
  • the hangers 12 with the load are hooked to the tractors 11 and are towed thereby along the rail 15. This permits transfers at high speed with minimal noise.
  • Fig. 6 shows a possible embodiment by way of example of a mixed system part in accordance with the present invention.
  • switch stations 50, 51 from which additional rails, the same as the rails 15, enter and exit and are only used for running of the tractors, as is clarified below. Between the switching stations runs a chain 45 parallel to the rail 15.
  • Figs. 7 and 8 show the possible embodiment of a switching station 50 or 51.
  • the switching station comprises a fixed frame 53 in which runs a moving frame 54, translatable between the two end positions shown in Figs. 7 and 8 by a motor 55 and a crank mechanism 56.
  • the moving frame 54 supports a straight rail section 57 and a curved rail section 58.
  • the straight rail section 57 constitutes a connecting section between the rail 15 upstream and downstream from the switching station.
  • the curved rail section 58 constitutes a connecting section between the rail 15 and the rail 52 upstream and downstream from the switching station.
  • a cam 42 executes release of the tractor from the hanger.
  • the switch is in the meantime placed in the position of fig. 8 so that the tractor can continue its travel along the rail 52.
  • the switch returns to the position of fig. 7 so that the hanger, hooked by the chain 45, can continue along the rail 15.
  • the chain conveyance zone and the tractor conveyance zone are slightly superimposed so that the hanger abandoned by the tractor can be recovered by the chain.
  • the hangers can thus complete their travel by chain while the free trucks without preloading can travel over a completely different path along the tracks 52 and be sent to a switching station 51 constituting the end of a chain movement section.
  • the switch upon arrival of a tractor 11, the switch is moved into the position of fig. 8 so that it permits passage and stopping of the tractor on the rail 15 immediately downstream from the station 51.
  • the switch then moves into the position of fig. 7 so that upon arrival of a hanger from the chain section it hooks to the tractor as explained above and it can tow it along the section 15 downstream from the station while the chain moves away from the track so that the hooking finger slides laterally out of the coupling 47.
  • the path of chain sections and tractor sections can be complicated.
  • the track sections for running only tractors can naturally also be arranged to pick up the trucks at the beginning of a chain section and send them to the end of a different chain section, depending on necessity and optimization of the lengths of the various tracks.
  • If there is need for greater motive force on the tractor path e.g. to climb a rising slope of a certain significance
