Definitions

  • the invention relates to a rail system for floor transport systems with at least two wheels having transport units.
  • Such rail systems especially for transport systems inside buildings, preferably production and storage halls, are known in which guide rails are recessed in the corridor or floor level, so that the wheels of non-rail-bound vehicles can run over them smoothly and smoothly. Furthermore, it is known in such rail systems to arrange the current conductors for supplying the drive power in the region of these guide rails, as can be seen, for example, from EP 0 151 982 A3.
  • a generic design according to DE 41 10 381 A1 shows parallel, spaced-apart depressions provided with strip-like current conductors in the corridor or floor level, one of which is designed as a recessed guide channel for the guide elements of the transport units, and vertically running flat side guide surfaces as well basically of the recessed guide channel has a first current conductor for supplying the drive power, and in which a second current conductor for supplying the drive power with the corridor or floor level is finally embedded in the second recess.
  • the object of the invention is to create a simpler design and a more universal usability. This can be made possible by reducing wear and easier interchangeability of the rail elements, as well as simplified branch routes.
  • the depressions are incorporated in a one-piece molded body which consists of an abrasion-resistant, low-wear plastic and which, in the installed state, is finally arranged in an installation channel in the screed with the corridor or floor level and further that the current conductor arranged in the base of the channel engages in undercuts machined on both sides in the side guide surfaces of the molded body.
  • Insulating potting compounds are used to isolate current-carrying conductors from one another; they consist of a castable plastic, which is to prevent voltage flashover by separating the current conductors. Therefore, relatively soft materials also meet these requirements after solidification. Therefore, they have only a low dimensional and abrasion resistance and no favorable sliding properties. Therefore, special guard rails are provided in the prior art, but they can also wear out. For replacement, the entire rail block must first be removed or hewn out of the hall floor screed and then the actual rail block must also be dismantled by destruction in order to remove the guide rails, which are not clearly visible, and replace them with new ones. This work requires long downtimes.
  • the one-piece molded body according to the invention is not produced by casting several individual parts in a mold to form a block, but rather consists of a uniform molded body in which the depressions are incorporated. It is also not poured into the floor screed when the hall floor is being built, but rather into an installation channel that is present in the screed and has been prepared beforehand. In the event of an exchange, it can be removed from the assembly channel at any time without damaging the hall floor.
  • the invention remedies this and provides a rail system of this type, which enables very favorable installation and laying conditions, and is easy to replace provides a high level of operational safety and long-term availability and largely avoids the risk of contamination of the guides.
  • the distance between the channel and the embedded conductor can be kept very small, e.g. be between 10 and 15 mm. This also results in a narrow construction of the entire molded body from a high-quality, largely abrasion-resistant plastic with good sliding properties, in which the two busbars are embedded, and which is removably fastened in an assembly channel.
  • This low-wear, abrasion-resistant plastic of the molded body also forms the vertically running, flat guide surfaces of the channel in which the guide elements of the transport units slide.
  • This compact design also allows a small width of the shaped body, about 100 to 120 mm, and also a thickness between 60 and 80 mm. This is also due to the fact that the channel (for the guide elements) only requires a width between 20 and at most 30 mm.
  • This narrow design which is only 100 to 120 mm wide (compared to 280 mm in the prior art), has the further major advantage that, apart from the very much lower weight, much narrower curve radii can be laid.
  • the measure mentioned appears to be particularly advantageous for operational reliability and interchangeability, in that the current conductor arranged in the base of the channel engages in undercuts in the molded body that are incorporated in the guide surfaces on both sides. It is also proposed that the Shaped bodies are subdivided into adjoining shaped body sections, at the section ends of which the current conductors have connecting straps.
  • This design prevents the build-up of contaminants in the channel. These are "swept clean" continuously by a brush or similar dirt trap on the transport units and get into the openings in the channel, from where they get into the receptacle and can be easily disposed of.
  • each of the Shaped body sections has electrical connection tabs connected to the current conductors, which lead laterally out of the shaped body and into a connection mounting recess in the screed and are used for connection to the power supply cables.
  • a branch switch piece which has a shaped body which is essentially triangular in plan, embedded therein a channel and a branch channel opening into it, and a current conductor running at a distance from the channel, and a branch line running at a distance from the branch channel but ending before the channel. Has current conductor.
  • the branch switch according to the invention is distinguished by the fact that it enables safe path control without an adjustable switch tongue. This eliminates all known difficulties and faults that occur in the case of adjustable switch tongues, in particular as a result of dirt and foreign bodies, which accumulate unobserved in the adjustment area of the switch tongues and obstruct or even block the remote adjustment.
  • This path control can be achieved absolutely operationally and reliably by using at least one in the channel slidably guided and / or side-adjustable guide element of the transport unit, which can be threaded into the branch duct.
  • This remotely operable adjustment of the guide element of the transport unit ensures that it is positioned in the channel either on one guide surface in one direction or on the other guide surface in the other (branch) direction and in each case follows that guide surface on which under the Effect of a low pressure force of the guide element is present.
  • cross or double switches can also be functionally formed if required.
  • the molded body 5 contains the channel 15, in the base of which one current conductor 12 is attached, the channel 15 being delimited by the two opposite guide surfaces 11.
  • the second current conductor 13 just like the first-mentioned, strip-like and of rectangular cross-section, is mounted in the recess 6 at a short distance from the duct 15.
  • the molded body 5 is inserted in the screed 27 into the assembly channel 4 and can if necessary, for example be removed or replaced at any time for repair or overhaul work. 1 that the current conductor 12 engages with undercuts 16 on both sides in undercuts 16 in the molded body 5.
  • the view of the branch switch piece according to FIG. 2 shows that the current conductor 13 has just continued through the switch region, while the branch current conductor 13a is curved at a distance from the branch duct 15a, however only up to the Her Community 26 and not connected to the current conductor 13, but isolated from it.
  • the centerpiece 26 of the switch is not provided with a switch tongue, but ends at an acute angle.
  • FIG. 3 shows a breakthrough 18 through which the current conductor 12 is interrupted and which leaves a passage to a cavity 19 in which a receptacle 21 is inserted for contaminants which fall into the channel 15 from above or collect there.
  • connection tabs 22, 23 of the current conductors 12, 13 are passed laterally through the molded body 5 and out, where they are connected to the power supply cables 24 in a connection mounting recess 25. This measure also serves to facilitate the replacement of the shaped bodies 5.
  • the openings 18 through the recessed conductor 12 have the contour of a parallelogram in plan view, the parallel legs of which are shorter than the angled legs. This prevents the pantographs from getting caught on disruptive edges.
  • FIG. 8 shows a schematic side view of a floor assembly 36 of a transport unit 30.
  • the guide elements 31 run in the channel 15, through which the travel path is predetermined is. At least one guide element 31 can be steered or rotated remotely in a manner not shown; this effects the directional control of turnouts.
  • the current collectors 32, 33 are arranged in an articulated manner on the handlebar levers 35 and pressed onto the current conductors by a spring arrangement (not shown in more detail).
  • 34 denotes a cleaning brush, which runs in the channel 15 and sweeps up accumulating impurities and feeds the openings 18.
  • This invention with the features shown and described here provides a rail system for floor or floor-based transport units which, in a new and surprising way, offers a number of advantages over the prior art and thus provides a step-by-step enrichment of the relevant technology.
