Definitions

  • the invention relates to a guide device for a rail-guided vehicle with a chassis, which has a chassis body with guide rollers with a vertical axis of rotation, which roll laterally on the rails, and a switching element, which is located in the direction of travel in front of the guide rollers and an operating device by a vertical axis is pivotable in the manner of a cantilever, in order to select the direction of travel when branching the rails, wherein at these branches between two rail sections formed with a U-profile, the vehicle is arranged in opposite directions and can be pivoted about a vertical axis, which are switched by the switching element and in their rest in both end positions on a side wall of the rail.
  • the invention relates to a guide device for single-track vehicles as used, for example, in rack-type conveyors. It is known to mount a floor rail and a top rail in one aisle, a rack operating device running in the rails having a chassis with a lifting frame on which a lifting or rack operating device can be moved up and down.
  • the rack operating device is provided with a cabin from which the up and down movement and the forward and backward travel of the rack operating device can be controlled.
  • a rail system is also known, in which guide rails are provided at the branching points in addition to an actual guide rail.
  • the vehicle is steered by inserting various guide rollers of the vehicle into the guide rail.
  • a middle guide roller is constantly engaged, while a left or right guide roller is alternately engaged with the associated guide rail when cornering.
  • straight driving or cornering is initiated by swiveling the guide flags.
  • the guide flag is swiveled directly from the device via the switching element.
  • DE-PS 497 725 describes a trolley which has switching elements with which guide vanes arranged at branches of the rails can be pivoted. In order to enable the pivoting, there must always be a gap between the tip of the guide vane and the edge of the U-shaped rail.
  • Such a switch circuit cannot be used in a rack operating device because of the high load that occurs.
  • a guide device for a rail-guided vehicle in which guide flags are provided at the branch points, which optionally release one of two rails.
  • Wedge-shaped switching elements are provided on the chassis body, which, like the guide vanes, can be pivoted about a vertical axis and which are controlled directly from the vehicle. The wedge-shaped switching elements switch the guide vanes from one position to the other.
  • the object of the invention is to provide a similar guiding device for rail-guided vehicles, in particular for storage and retrieval machines, with which the vehicle can be guided outside the branching points on a conventional rail, for example a railroad rail.
  • the guide vanes have a part which projects upwards over the side webs of the rails, on which the switching element engages when switching over, and in that the switching element is arranged above the side webs of the rails, in that the rails unite before and after the branches laterally free rail head and that the guide rollers, which are height-adjustable, roll in these areas on the rail head flanks and the rails between them and that ramps are arranged in front of the branches on both sides of the free rail head, to the open with the top Guide U-shaped rail section, the guide rollers are raised along the ramps, so that the guide rollers run in the area of the branches on the inside of the side webs.
  • the guide vanes can rest on the rail walls, the necessary stability is given when the guide rollers touch it.
  • the front guide roller which is located on the same side as the guide vane, hits the tip of the guide vane frontally if the latter is at a small distance from the side wall of the rail. This would result in the guide device breaking.
  • An embodiment of the invention provides that bearing axes of the guide rollers bear with their lower ends on the ramps, the Bearing axles are advantageously pressed down by springs so that guidance on the running rail is ensured even when driving straight.
  • the guide rollers can also be lowered by gravity.
  • a locking device may be provided.
  • the switching element protrudes laterally beyond the side webs of the guide rails in the switching position.
  • the part of the guide vane protruding from the rails is advantageously formed by a bolt which is arranged at the free end of the guide vane.
  • the bolt can carry a role.
  • FIG. 1 shows schematically a view of a rack operating device with a guide device according to the invention
  • Fig. 2 also shows schematically a side view of a branch point
  • Fig. 3 shows schematically a plan view of a branch point according to Fig. 2
  • Fig. 4 shows a section along line AA of FIG. 3
  • FIG. 5 shows a section along line BB of FIG. 3
  • FIG. 6 shows a side view of the branching point analogous to FIG. 2, the vehicle being shown when entering the branching point 7 shows the same branching point with the same vehicle position in a top view, with the guide vane and the switching element in the position for driving straight ahead
  • FIGS. 8 to 10 show top views of the branching point in different stages of cornering.
  • the shelf operating device shown in FIG. 1 has a lower undercarriage 1, a lifting mast 2 and an upper tail unit 3 in a conventional manner.
  • the lifting carriage 14 is mounted on the lifting mast 2 in a vertically movable manner. In the lifting carriage 14 there is also the operating cabin from which the control of the control device takes place.
  • the tail unit 3 of the upper guide device has upper guide rollers 4 which are guided in an upper guide rail 5.
  • the special type of upper guide at the branching points is not dealt with in the context of this description.
  • the undercarriage 1 has one undercarriage body 6 each at the front and rear, which in the exemplary embodiment carries one roller 7 and four guide rollers 8.
  • the undercarriage body 6 can be mounted on the undercarriage 1 both rigidly and also laterally displaceably or rotatably.
  • the guide rollers 8 are guided along a lower rail 9.
  • the lower rails 9 are usually formed by conventional railroad tracks outside the branching points, and the guide rollers 8 run to the left and right of the rail head 10 on the rail head flanks. The vehicle is thus safely guided on the rail 9.
  • the rails are designed as a U-profile. H. lateral guide walls 17 are provided, on which the guide rollers 8 now run off on the inside. Horizontal side webs 18 are provided on the side of the rail head 10, as can be seen from FIG. -5.
  • Oblique ramps 16 lead to the horizontal side webs 18.
  • the ramps 16 raise the guide rollers 8, which are mounted on axles 19, so that the undercarriage body 6 can move freely into the U-profile area of the rails 9.
  • the railroad track that forms the travel rail 9 is continuous and is supplemented by the side webs 18 in the region of the branching point.
  • the axes 19 of the guide rollers 8 can be acted upon, for example, by springs 20, which press them down when leaving the branch point.
  • the chassis bodies 6 are provided with wedge-shaped switching elements 11, which are located in front of the foremost guide rollers 8 in the direction of travel.
  • the guide flag 12 is shown in the position that would require the rack operating device to be driven straight ahead.
  • the rack operating device which runs on two undercarriage bodies 6, is guided on the running rail 9 by means of the guide rollers 8.
  • the guide rollers are raised by the ramps 16 and the lateral guidance of the undercarriage body 6 is now taken over by the side walls 17 of the U-shaped area of the running rail 9.
  • the switching element 11 is brought into position, as shown in FIG. 8.
  • the switching element 11 protrudes laterally beyond the web 17 of the rail 9 in the U-profile area.
  • the switching element 11 is arranged above the running rail 9.
  • the front control surface 13 of the switching element 11 presses against the bolt 15, which is arranged at the tip of the guide vane 12 and also protrudes beyond the side webs 17 of the travel rail 9.
  • the guide vane 12 is thereby pivoted until it rests against the opposite web 17 and is supported on it.
  • the shelf operating device now moves around the curve, as shown in FIG. 10. It is important that the guide vane 12 can rest snugly against the web 17 and also not move away from it when the first chassis body 6 passes is driving. There is therefore no hitting of the guiding flags 12.
  • the second chassis body 6 of the rack operating device follows the first chassis body 6 without further measures.
  • a dead center lock can be provided for the guide vanes 12, which ensures that they remain in the respectively set position.
