Definitions
- the invention relates to a drive system for escalators and moving walks.
- escalators or moving walks are driven indirectly or directly via electric motors.
- at least one reduction gear is provided, and if necessary, transfer gears can also be used in the area in which the components of escalators or moving walkways can be driven together.
- Such components are the step or pallet belt and, if necessary, also the handrail, provided that there are no separate drive means for the same.
- the step or pallet belt is usually moved by means of link chains, the direction of which is changed in the deflection areas via deflection elements provided there as sprockets.
- step or pallet belt can be deflected as far as possible without the desired polygon effects and, when the drive is common, the step or pallet belt and the handrail run synchronously with one another, so that one does not precede the other - or lags behind, so that personal injury cannot always be excluded.
- the Pallet belt link chains are used, which also have a larger division depending on the step or pallet width, for example about 200 or about 400 mm.
- These enlarged chain divisions, which are desirable per se, may, however, cause problems - as far as the polygon effect in the deflection and possibly also synchronous drive mode of the handrail is concerned.
- escalators and moving walks which can be used in interior areas, for example of department stores or the like and which are equipped by means of drive chains, in relation to which relative low forces that interact with the steps or pallets.
- Pallet bolts and rollers are positioned in the respective joint areas of the drive chains.
- the polygon effect which is still present when the deflection chains are deflected - in particular in the case of an enlarged chain pitch - is problematic.
- DE-A 19 849 236 is a method and a device for guiding a chain in the area of chain wheels of a continuous conveyor, in particular an escalator or an escalator, in that the chain is fed straight to the respective chain or drive wheel, whereby according to the Engagement of a first element of a first chain link of the chain center in the chain or drive wheel, a constant adaptation of the effective chain radius is brought about by setting a constant speed in the chain center.
- the chain or drive wheel in particular in the area of its outer diameter, should be made narrow to accommodate the chain bolts, with at least one rail-like guide profile being arranged directly next to the chain or drive wheel in this area.
- a similar device for guiding a belt continuum for escalators or moving walks can be found in DE-A 0 711 725.
- the chain rollers are guided by means of a support rail with one raceway and by means of a compensating rail with one raceway.
- the chain rollers slide from the straight track of the support rail onto the curved track of the compensating rail and from there at a tangent point into engagement with the chain wheel.
- the chain rollers From the running track of the support rail to the tangent point, the chain rollers become perpendicular to the running direction Move direction by a distance to the chain wheel measured transversely to the running direction, which has an advantageous effect on the smooth running of the belt continuum.
- This special curve shape of the connecting part is intended to reduce the polygon effect.
- polygon and deflection effects occur, which have a negative effect in particular on the smooth running of the escalator or escalator.
- the polygon effect is created by the polygonal shape of the chain on the sprocket.
- the effective radius on the sprocket varies, causing the chain speed to fluctuate between a maximum and a minimum value.
- the circulation effect is a consequence of the angular momentum that is transmitted from the sprocket to the chain links and thus the steps or pallets.
- this angular momentum is initially retained by the inertia of the system, which leads to the so-called rolling of the chain.
- the angular momentum is reduced by friction in the chain or, if the chain guide element is present, by impacts between the chain and the guide.
- the aim of the subject matter of the invention is to provide a novel drive system for escalators and moving walks, in particular equipped with link chains with a larger pitch, in which drive chains with normal pitch as well as with enlarged pitch with minimized polygon effect in the area of deflection elements can be changed in their direction of travel. This both in the entry and exit area of the respective drive chain.
- a drive system for escalators and moving walks including at least one drive motor, possibly cooperating with a gear, at least one drive chain designed as a link chain, deflection elements for the drive chain and a device for changing the speed of the drive chain, or components thereof Inlet and / or outlet area, in the vicinity of the respective deflection element.
- the subject of the invention shows how the speed differences between the drive chain and the deflection element, which are to be viewed as critical, can be effectively countered on the one hand in the inlet area and, on the other hand, if necessary also in the outlet area, in that individual or more chain links, or at least one or chain roller of the drive chain before the inlet or after the outlet into or out of the deflection element, which is preferably designed as a chain wheel, is deflected in its running direction.
- the inlet / outlet area is not to be looked at selectively; rather, depending on the chain pitch, it covers a defined area before or after the respective deflection element.
- the speed is influenced due to changes in the radius. There are deviations in the desired constant speed.
- the chain is typically guided over a track before the entry into the chain wheel, which in the prior art has a rather steady curve shape.
- the invention now takes advantage of the fact that the position of the upstream chain links / chain or track rollers is influenced . can be, depending on the phase position of the sprocket. In those positions in which a higher speed is geometrically predetermined by chain engagement, the position of one or more of the mentioned chain links, or respectively track or chain rollers, is to be influenced in their position by the curve shape of the upstream or downstream track, in such a way that it is too A speed reduction A increase, which overall reduces the speed fluctuations in the inlet / outlet area of the drive chain. This goes hand in hand with an equalization of the polygon effect Speed adjustments are no longer perceived by users of the escalator or escalator as bumps.
- the smoothness and the service life of the components of the escalator or moving walk can be increased considerably.
- the subject of the invention largely overcomes the polygon effects caused by enlarged chain divisions of the step chain or pallet chain, which have a negative effect on the deflection element designed as a chain wheel, and possibly also on the handrail wheel.
- the economically positive effects of an increased chain pitch (reduction of the chain price) can thus be effectively integrated into existing drive concepts.
- the chain pitch can be increased in two steps. Given the same conditions (step or pallet tread surface length of about 400 mm), another possible chain division would be 200 mm and 400 mm, i.e. two links per step or pallet or one link per step or pallet.
- the subject of the invention is applicable to all types of escalators or moving walks, but preferably for the drive chains of an escalator or moving walkway that can be used in the interior of buildings. It is therefore not only the effect of the increased chain division, but rather the combination of the same with suitable measures to reduce the polygon effect, which now leads to an economically interesting solution, especially for drives for department store escalators and moving walkways.

- the subject matter of the invention takes advantage of the fact that the position of the upstream chain rollers 2 can be influenced as a function of the phase position of the deflection element 4.
- the position of at least one of the chain rollers 2 should be influenced by the curved elevation 7 of the guideway 6 in such a way that there is a speed decrease or increase, the overall speed fluctuations in the inlet area 8 and thus the polygon effect is reduced.

- the height h of the elevations 9 is a function of the phase angle ⁇ of the chain wheel 4 and simulates the upward and downward movement of the drive chain 1 given by the rolling in of the drive chain 1 in the run-out area 1.
- the height h of individual elevations 9 can vary depending on the angular momentum to be reduced, in the running direction seen the drive chain 1, be different, ie if necessary, it can be reduced in the running direction 'of the drive chain 1.
- the distance I 'of the elevations 9 is matched to the respective chain pitch of the drive chain 1 used.
