Definitions
- the invention relates to a device for continuously measuring the respective position of a rail vehicle in motion on a rail path by means of a measuring path arranged parallel to the rail path, on which the position of each rail vehicle is measured and which feeds the measured position of each rail vehicle to a computer which controls the drive means of material handling equipment.
- the invention has for its object to provide a device for continuously measuring the respective position of a rail vehicle in motion, which provides flawless measurement results and which can still be produced inexpensively.
- switching elements are arranged in the measuring section distributed over their length, which consist of mechanically actuable electrical switches provided with an elastic switching flag,
- switching flags are designed and / or arranged so that - even with maximum sinus travel and considerable wear of the wheel and / or the rail - one from the circumferential surface of the wheel, that is to say the tread or the flanged wheel moving rail vehicle are touched and pressed down, - that the switching flags are designed and / or arranged in such a way that they extend almost to the head of one of the two rails of the rail path,
- the design and / or the arrangement of the switching flag and the small distance between the individual switching elements from one another ensures a very precise, continuous detection of the position of the rail vehicle, on the basis of which the drive means of the changeover Impact devices can be controlled so that the handling devices are each with high accuracy in the right place in relation to the rail vehicle in question and move synchronously at the right speed.
- the switching lugs assigned to the switching elements can be mounted on the switching elements themselves or independently of them.
- the device according to the invention can be produced particularly inexpensively in that commercially available switches can be used as switching elements, which are to be provided with a special switching flag or to which a switching flag can be assigned.
- the switching elements - individually or combined into segments - are elastically supported.
- the switching elements are arranged below the rail head level, so that damage is largely excluded.
- the measuring section is formed by at least one circuit board on which the switching elements are soldered.
- the measuring section can be formed by at least one sheet metal plate onto which the switching elements are screwed, riveted or glued.
- the measuring section is formed by at least one connector strip, into which the switching elements by means of the electrical Connection pin connectors are inserted.
- the switching elements can easily be replaced individually, so that the maintenance and repair of the measuring section also requires only very low costs.
- the switching flag is designed and / or arranged in such a way that it can also absorb lateral forces. This prevents the switching flag from being displaced in the longitudinal direction of the rail by the wheel traveling over it.
- a particularly expedient embodiment of the object of the invention consists in that the switching flag is provided with a crank at its end facing the switching element.
- the switching elements are covered by a U-shaped sheet. This prevents damage and contamination of the switching elements.
- cranking of the switching flag is directed downward and engages in the cranking of one of the legs of the U-shaped plate covering the switching element.
- the service life of the switching flag can also be increased in that the switching flag is provided with a roller in the area in which there is contact with the wheel flange or the wheel flange of the rail vehicle.
- the transverse forces acting on the bearing of the switching flags are reduced as a result.
- the measuring accuracy of the device according to the invention is independent of the length of the measuring section and depends only on the mounting distance of the switching elements from one another. In the case of switching elements arranged directly next to one another with a width of, for example, 6.5 mm, the measurement accuracy is also 6.5 mm. According to a further feature of the invention it is therefore provided that the distance of the individual switching elements from one another corresponds at least to the thickness of a switching element.
- Fig. 1 to 3 each have a half cross section through the upper
- the device according to the invention essentially consists of the measuring section shown in FIGS. 1 to 6, which is formed from a plurality of switching elements 1 arranged one behind the other.
- Each switching element 1 is assigned a switching lug 2, which extends from the circumferential surface of the wheel 3 - that is to say the wheel flange 3L (FIGS. 1 to 3) or the wheel flange 3S (FIGS. 4 to 6) - of a rail vehicle traveling over it on rails 4 is touched and pressed down.
- the switching flag 2 pivots about a pivot point 5, so that a switching button 6 provided on the switching element is actuated and a signal is thereby triggered.
- the triggered signal is fed to a computer, not shown, which controls the drive means of a handling device, also not shown.
- the switching elements 1 which form the measuring section and are arranged one behind the other are plugged into a plug connector 8 by means of pin plugs 7, the pin plugs 7 effecting the electrical connection.
- the switching elements 1 can also be fastened to a circuit board with solder connections or screwed, riveted or glued onto a sheet metal plate.
- the switching flag 2 has a downward offset 9 and the switching elements 1 are covered by a U-shaped plate 10. One of the legs of the U-shaped plate 10 engages in the crank 9 of the switching flag 2.
- the switching flag 2 In the area in which the switching flag 2 touches the wheel flange 3L or the wheel flange 3S of the wheel 3 takes place, the switching flag 2 is provided with a roller 11 (Fig. 3) or with a roller 11 '(Fig. 4).
