Definitions

  • the invention relates to an infeed rail for escalators or moving walks, which is designed to support a step chain with inner rollers and rollers arranged on the outside when it enters a chain wheel. Furthermore, the invention relates to a passenger conveyor device, in particular an escalator or a moving walk, with at least one step chain, at least one chain wheel and at least one inlet rail, the step chain comprising protective rollers arranged on the inside and running rollers arranged on the outside.
  • Such infeed rails serve in particular to reduce vibrations of the step chain of a passenger conveyor when it enters the respective chain wheel and thereby in particular to increase the smoothness of the passenger conveyor.
  • the chain pitch increases, which is particularly attractive for reasons of cost, the problem of the step chain vibrating when it enters a sprocket increases.
  • rollers outside of the chain links By arranging the rollers outside of the chain links, the replacement of such rollers is significantly simplified and possible within significantly shorter times than with internal rollers. This significantly reduces possible downtimes as a result of the need to replace rollers.
  • Track rollers arranged outside the chain links are also not used for engaging the chain wheels. This is done by means of the protective rollers on the inside.
  • the additional rollers outside the chain links advantageously reduce the wear on the inner protective rollers of a step chain.
  • Such a step chain with rollers arranged on the outside and protective rollers arranged on the inside which can be used particularly advantageously together with the present invention, is for example in FIG DE 10 2015 212 031 A1 described.
  • a passenger conveyor device in which a step chain with inner rollers arranged on the inside and rollers arranged on the outside is supported when it enters a chain wheel.
  • a first running surface is provided on which the rollers roll between the chain wheels.
  • an inlet rail is provided which has a second running surface which the protective rollers support when they run into the chain wheel.
  • the support of the rollers changes into support of the protective rollers when they enter a chain wheel. The occurrence of vibrations of the step chain when running into a chain wheel is not completely prevented.
  • the protective rollers are more stressed by the support.
  • the present invention is based on the object of further reducing the occurrence of vibrations in a step chain with protective rollers arranged on the inside, i.e. inside the chain links, and running rollers on the outside, i.e. outside the chain links, when entering a sprocket.
  • the proposed solution provides an inlet rail for escalators or moving walks, which is designed to support a step chain with protective rollers arranged on the inside and rollers arranged on the outside when it enters a chain wheel.
  • the inlet rail has a first support surface for supporting the protective rollers and a second support surface for supporting the running rollers.
  • the second support surface is arranged next to the first support surface.
  • a roller is usually not arranged at every connection point of the chain links and the number of rollers is thus less than the number of protective rollers. If the rollers were exclusively supported, the step chain would therefore vibrate comparatively strongly in the area between two rollers. In particular, this leads to an unsteady run-in of the step chain into the sprocket.
  • the first support surface thus ensures a reduction in vibrations and improved smoothness. At a If only the protective rollers were to be supported, they would be more stressed. It is therefore advantageous that the rollers are also supported when they run into the sprocket.
  • the first support surface has a smaller width than the second support surface.
  • the sprocket width and the width of the first support surface are advantageously adapted to the step chain in such a way that the protective rollers of the step chain can run into the sprocket and can be supported laterally by the first support surface of the inlet rail.
  • the first support surface therefore does not support the protective rollers in particular over the entire roller width.
  • the protective rollers are only supported on one side area.
  • the protective rollers do not protrude beyond the chain links of the step chain.
  • the protective rollers in particular have a diameter that is equal to or less than the height of the link plates.

  • the protective rollers are each supported by means of the first support surface in such a way that the protective rollers supported by the first support surfaces are in parallel engagement with the sprocket, in particular in the area of the top dead center of the sprocket.
  • the protective rollers can advantageously contact both the chain wheel and the first support surface, in particular in the area of the top dead center of the chain wheel.
  • the protective rollers are not released by the first support surface, in particular not in sections, but are still loaded in engagement with the sprocket, in particular up to the top dead center of the sprocket, in particular at the top dead center of the sprocket.
  • the first support surface is in particular not provided to avoid contact between the chain wheel and the protective roller supported by the first support surface.
  • the first support surface advantageously stabilizes the running-in of the protective rollers into the chain wheel and advantageously leads to reduced oscillation of the step chain.
  • the first support surface is made shorter than the second support surface of the inlet rail.
  • the first support surface of the inlet rail does not protrude beyond the dead center of the chain wheel, whereas it can be provided that the second support surface protrudes beyond the dead center of the chain wheel.
  • the inlet rail has a length between 200 mm and 500 mm, in particular between 300 mm and 400 mm.
  • the longitudinal extent of the second support surface of the total length of the Infeed rail corresponds.
  • the longitudinal extent of the first support surface can in particular correspond to 50% to 80% of the total length of the inlet rail.
  • the first support surface is made of a first material and the second support surface is made of a second material.
  • the first material is advantageously more resilient than the second material.

  • the first support surface has in particular a higher arrangement height than the second support surface.
  • the inlet rail is thus advantageously adapted to the fact that the rollers of the step chain usually have a larger diameter than the protective rollers of the step chain.
  • a first piece of the inlet rail is advantageously a first component which has the first support surface
  • a second piece of the inlet rail is a second component which has the second support surface.
  • this can make it easier to install the inlet rail.
  • the respective component can also be replaced individually.
  • Another advantage is that the height offset described above can be easily adjusted due to the different diameters of the protective rollers and the running rollers.
  • the first component and the second component are connection-free. In such a configuration it is provided in particular that the first component and the second component are not directly connected to one another.
  • the first component is arranged on an element of a passenger conveyor device and the second component is arranged on an element of this passenger conveyor device.

  • the low points are advantageously determined on the basis of a simulation of the theoretical curve profile of those protective rollers that are arranged between two successive rollers when they run into a chain wheel, neglecting the dead weight of the step chain.
  • the arrangement of the first support surface and the formation of the height profile are advantageously carried out in such a way that the protective rollers would contact the support surface at the specific low points.
  • the further first height profile of the first support surface is advantageously determined in such a way that it advantageously remains below the simulated curve shape, preferably 0 mm to 15 mm (mm: millimeter) below the simulated curve shape.

  • This configuration is particularly advantageous when damping elements are inserted between the teeth of the chain wheel. The damping elements are loaded more evenly and wear out more evenly. This further contributes to improved smoothness.
  • the second height profile of the second support surface describes a falling curve starting from the maximum over the vertical projection of the dead center, i.e. in particular beyond the area around the vertical projection of the dead center, the falling curve in particular following the circular path that a roller of the driven step chain covers, in particular would theoretically cover without support by the infeed rail, in particular in the corresponding area in which the second support surface is arranged.

  • the second height profile 16 of the second support surface 12 begins in relation to the illustration in FIG Fig. 3 viewed from left to right, initially flat and rises to a maximum 17 before the dead center of the chain wheel 30 and then follows the circular path that a roller 22 writes when the step chain is in engagement with the chain wheel in the corresponding chain section.
  • the maximum of the second height profile 16 lies in the area of the dead center of the chain wheel 30.
  • Fig. 4 shows an even smaller section 70 of a passenger conveyor device, with the intended inlet rail 10 opposite Fig. 3 is shown enlarged.
  • the inlet rail 10 can have a total length of 350 mm.
  • the step chain of the passenger conveyor is in Fig. 4 not shown, but the curves 51, 52, which would theoretically describe the protective rollers of the step chain arranged between two successive rollers.
  • Fig. 4 it is shown here again how the first support surface 11 of the inlet rail 10 is determined by the low points 50 of the curves 51, 52.
  • a perpendicular 65 running through the center of the first component 13 is shown.
  • the first component 13 and thus in particular also the first support surface 11 are designed mirror-symmetrically with respect to this perpendicular 65.
  • the dead center 31 of the chain wheel 30 is also symbolically represented, the maximum 17 of the second support surface 12 in this exemplary embodiment being located exactly at the vertical projection 60 of the dead center 31 of the chain wheel 30 onto the second support surface 12.
  • the maximum 17 can vary in a region 18 around the vertical projection 60 of the dead center 31 of the chain wheel 30 onto the second support surface 12.
  • the area 18 preferably begins up to 10 mm, in particular up to 5 mm, in front of the vertical projection 60 and ends up to 10 mm, in particular up to 5 mm, behind the vertical projection 60.
  • the protective rollers of a step chain always enter the sprocket 30 at the same height, which benefits the smoothness of running.
  • damping elements 33 which are advantageously inserted between the teeth 32 of the chain wheel 30, are evenly loaded and thus evenly worn, as a result of which the smoothness of operation is increased even further.
  • the infeed rail is designed to support step chains in which only one protective roller is arranged between two successive rollers, but also to support step chains in which three protective rollers are arranged between two successive rollers. This changes, in particular, the first height profile 15 of the first support surface 11. Because a different chain pitch or a different ratio of rollers to protective rollers changes the curves of the protective rollers arranged between the rollers.
  • the first height profile 15 of the first support surface 11 is also determined by the respective low points of the correspondingly changed curve courses, in particular in the manner as explained for the example with two castors lying between two successive rollers, with a higher number of castors correspondingly more Low points are to be considered.
