Definitions

  • the trolleys usually have a drive wheel placed above the rail and bucking rollers place below it. Adherence of the powered upper wheel on the monorail is generally sufficient for level movement and along slight rises.
  • the general object of the present invention is to obviate the above mentioned drawbacks by supplying a transportation system of the self-powered type which would allow ascending and descending ramps with relatively steep slopes with trolleys of limited size and complexity free from swinging and with thrust of the drive wheel on the rail substantially a function of the slope negotiated.
  • a suspended rail system for the transportation of loads hung on trolleys each having an upper drive wheel and a plurality of lower bucking rollers running on the upper surface and on the lower surface respectively of the rail, said rail having level sections and sloped sections, and characterized in that in combination the upper wheel and the lower rollers are rigidly connected to each other, the wheel, rollers and point of application of the load bearing on the trolley are mutually arranged so that, when running in sloping sections, the straight line of application of the total weight bearing on the trolley does not pass through the centre of the wheel, to produce a rotation moment opposed by at least one of said plurality of wheels.
  • the rail has uniform thickness substantially equal to the distance between the rollers and the wheel in the horizontal sections and in sloped straight sections, in curved sections with upward convexity decreasing in thickness in a filleted manner to maintain contact between the rollers and the wheel and the respective surfaces of the rail along said curved sections with minimal play and no interference.
  • FIG. 1 shows schematically a sloping section of a system provided in accordance with the innovative principles claimed herein and indicated generally by reference number 10 with independently powered trolleys running on a rail 11.
  • Each trolley comprises an upper wheel 13 for drive and support and kinematically connected to an electric motor 14 and a pair of lower bucking idling rollers 15 and 16.
  • the lower idling rollers and the upper wheel are supported on the trolley frame rigidly so as to be positioned at the angles of an imaginary, invariable and substantially isosceles triangle.
  • idling rollers 18 for guiding along the side profile of the rail.
  • the trolley 12 comprises articulated means of support 17 on which to hang transported loads, e.g. automobiles parts along an assembly line.
  • the point of application of the total load bearing on the trolley, the rollers 15, 16 and the wheel 13 are mutually arranged so that when running in the sloping sections the vertical straight line passing through the centre of gravity of the load does not pass through the centre of the wheel.
  • said straight line passes upstream of the upper wheel and of the lower wheel further downstream, with reference to the inclination of the rail and hence, in the case of the annexed figure, passes to the left of the wheel and the roller 16.
  • said centre of gravity is substantially arranged on the vertical of the upper wheel.
  • the rail has a uniform thickness "a" equal to the distance between the lower rollers and the upper wheel.
  • the rail decreases in thickness in a filleted manner so as to maintain contact between the rollers and the wheel with the respective surfaces of the rail with minimum play and without the interference which there would be otherwise, The reduced thickness can be obtained simply by milling a normal rail with uniform thickness.
  • the rail increases in thickness in a filleted manner so as to recover the play which there would otherwise be between the lower rollers and the rail.
  • the variation in thickness can be obtained starting with a rail with uniform thickness by fixing thereto appropriate shimming.
  • the figure shows in broken lines the development of a rail of the know art with uniform thickness.
  • the exact shape of the rail in accordance with the present invention is easily obtained with trajectories described by the rollers and by the wheel during movement of the trolley along a line representing its path.
  • trolleys Running on rises is thus assured with a very simple mechanical embodiment of the trolleys which is small and truly economical.
  • the trolleys are prevented from any swinging movement in the direction of travel, whether in level or rising travel, allowing processing of the objects transported at any point of the path even with the trolley moving.
  • the physical structure of the trolleys can be different from that shown by way of example, e.g. the rollers could be in a number different from that shown; it is sufficient that during ascending travel the straight vertical line passing through the centre of gravity of the total weight bearing on the trolley does not pass through the centre of the upper wheel and that at least one lower roller be in a position such as to oppose the moment thus generated in such a manner as to increase the thrust of the wheel on the rail.
  • the point of application of the load transported on the trolley must be selected to supply the arm "b" at least enough to produce the necessary adherence of the wheel according to the slope of the rail.
  • the joint to which the trolley load is hung could be placed at a greater distance downward from the lower rollers.
  • FIG. 2 shows a construction variant of the trolley which furnishes an arm b' greater than the arm b of FIG. 1 without substantially increasing the overall vertical dimension of the trolley.
  • the trolley 12' (otherwise similar to the trolley 12 of FIG. 1) is equipped at the bottom with two pins 23 24 respectively arranged in a plane parallel to the rail.
  • a reticulated structure 25 bearing at the bottom a support 26 for the load to be transported.
  • the plane containing the pins is horizontal and the reticulated structure rests on the pins 23 and 24 with the inside of the edges 27 and 28 respectively. In this position the vertical passing through the centre of gravity of the load is substantially on the centre line between the two pins.
