Definitions
- the invention relates to a moving walk according to the preamble of claim 1. Such a moving walk is already from the DE-A-2 223 823 is known.
- rollers i.e. either the pallet chain rollers, the guide rollers of the pallets as well as the drag rollers over which the opposite one End of the pallet is guided, to be equipped with plastic.
- rollers i.e. either the pallet chain rollers, the guide rollers of the pallets as well as the drag rollers over which the opposite one End of the pallet is guided.
- plastic rollers is slightly larger than that of metallic rolls.
- the Rolling friction of rolling bearings, such as ball bearings is slightly less than that of plain bearings.
- the invention is therefore based on the object of a moving walk according to the preamble of claim 1 to create the is improved in terms of running properties, wherein the construction effort is nevertheless reduced.
- the existing ones are provided Omit drag rollers and replace the pallet instead To link driving elements directly to pallet chain links.
- this allows the running properties improve, because there are less friction generating Roles available.
- the leadership is improved because that Driving element is supported by the associated chain link not just on one, but on the two neighboring ones - provided anyway - pallet chain rollers, so that these are used twice. In this context it is particularly cheap if the driving element is pretty much in the middle of the pallet chain links is supported by one to achieve uniform loading of the two adjacent roles.
- the solution according to the invention also has the advantage that the Inversion points can be constructed more simply.
- the as Handlebar trained driving elements becomes the required Length compensation guaranteed on the bypass bends. It is preferred that the positioning of the bearing points of the driving elements takes place so that the driving elements with just guided Pallet about 5 to 6 ° inwards, i.e. to the middle of the pallet are inclined. Then they are in the bypass tilted outward about the same amount.
- the necessary chain tensioner are the pallet chains tightened in every situation so that the pallets do not collapse can.
- the guide rollers and the pallet chain also uses commercially available parts can be. It only needs every second inner flap the pallet chain with a corresponding hole for provide the mounting of the bearing pin for the driving element his.
- the bearing pin is non-rotatable connected to the inner plate and the driving element rotates itself on the bearing pin, which thus has a large bearing surface provides low surface pressure. Because of the low Deflection according to the invention is particularly favorable that with simple plain bearings can be worked, so that expensive and additional ball bearings are unnecessary.
- FIG. 1 One shown in Fig. 1 only in the form of a small section Moving walk 10 has a pallet 12, which on a Pallet chain 14 is guided.
- the pallet 12 opens Guide rollers 16, which are integrated into the pallet chain 14 are, as is known per se.
- the pallet chain has two rollers or chain rollers 18 on the same distance from each other and from the Guide roller 16 and also the guide roller 16 of the next one Pallet are spaced.
- the pallet is on both sides a pallet chain is provided, only one side in FIG. 1 is shown.
- the pallet 12 is on both sides at its front end Guide roller 16 and a hollow axis 17 on the pallet chains 14, of which the right-hand pallet chain 14 is shown in FIG. 1 is supported.
- the pallet is at its rear end 12 supported according to the invention on the pallet chain 14, and via pallet support elements, in particular pallet bolts 20, and driving elements 22. Accordingly, separate Rails for the drag rollers that are otherwise required and all chain rollers 18 and guide rollers 16 can run in succession on a common rail.
- the takeaway elements 22 is designed so that it is not only the support in the pallet advance, but also the suspension of the Pallets in the pallet return enabled.
- the pallet 12 is accordingly at four points on the pallet chains 14 supported on both sides and is therefore precise and managed safely.
- the Pallet bolt 20 laterally to the pallet chain 14 from the Pallet 12 out.
- the pallet is preferably made of die-cast aluminum formed and the pallet pin 20 is cast in. It runs in a bearing recess or bore 24 of the Driving element 22, so that the driving element 22 around the Axis of the pallet pin 20 is pivotable.
- the driving element 22 extends fairly widely over almost the entire width between inner plates 26 of the pallet chain 14. Instead of attaching to outer plates 36, it is preferred, the storage of the driving element 22 on inner tabs 26 made after this from the geometry of the chain drive are more suitable here.
- the driving element 22 is pivotable on the pallet chain 14 via a bearing pin 28 stored.
- the bearing pin 28 is non-rotatable on the inner plates 26 and cannot be lost held, preferably by means of one in one Groove 30 introduced bearing rings, not shown, and one shown retaining clip 32.
- the driving element 22 is on the bearing pin 28 is pivotally mounted. So that results a double swiveling mounting of the handlebar trained driving element 22 after both bearing axles extend horizontally.
- This storage allows the pallet 12 to be moved without problems on the reversing sheets, shown in Fig. 1 horizontal position of the pallets, in which they are in the Operating position, the pallet pin 20 of the associated Guide roller 16 is slightly closer to the same pallet 12 than the bearing pin 28.
- the driving element 22 is thus somewhat towards the center of the pallet inclined, and the swivel mobility is fully sufficient, for shortening by the kind of a tendon Acting pallet 12 in the area of the transfer bends to wear.
- the driver element 22 is preferably quite small and very large compact and solid. For example, there is a center distance between the pallet pin 20 and the bearing pin 28 of 3 cm completely adequate. The construction is as compact as possible with a width of the driving element 22 between the inner plates 26 of about 3 cm. The driving element 22 is thus very stable against canting and has a close guide for the pallet 12. The pallet bolt extends accordingly 20 just a little above the inner plates 26.
- bearing pin 28 is approximately extends in the middle of the inner tabs 26. Then about half load acting on the driving element 22 from the neighboring one Chain roller 18 and the other half of the load of the guide roller 16 of the following range added. Surprisingly, this configuration is particularly favorable for a quiet and precise run when plastic or Rubber rollers are used.
- the guide roller 16 is preferred harder, so it consists of a harder one Plastic on its surface, while the guide roller 18th as well as the idle, removed from the driving elements 22
- Guide roller 18 made of a softer plastic exists in which also the ball bearing in question directly is embedded.
- All rollers i.e. the guide rollers 16 and the chain rollers 18 are in the moving walk 10 according to the invention with ball bearings 34 equipped. This results in a light and quiet Run and secure support.

Abstract
Description
Die Erfindung betrifft einen Fahrsteig gemäß dem Oberbegriff von Anspruch 1. Ein derartiger Fahrsteig ist bereits aus der DE-A-2 223 823 bekannt.The invention relates to a moving walk according to the preamble of claim 1. Such a moving walk is already from the DE-A-2 223 823 is known.
Bei derartigen Fahrsteigen, aber auch bei Fahrtreppen, werden Paletten über Führungsrollen, die auf Schienen laufen, mittels beidseitig laufender Palettenketten bewegt. Die Paletten sind über Hohlachsen mit den Führungsrollen verbunden, die über Wälzlager, üblicherweise über Kugellager, an den Kettengelenken gelagert sind.With such moving walks, but also with escalators Pallets over guide rollers that run on rails by means of Pallet chains running on both sides moved. The pallets are connected via hollow axles to the guide rollers, which via Rolling bearings, usually via ball bearings, on the chain links are stored.
Damit Fahrtreppen, insbesondere aber Fahrsteige, die häufig im Dauerbetrieb laufen und sehr lang sein können, möglichst wenig Energie verbrauchen, ist es wichtig, die Reibung bereits im Bereich des Antriebs der Paletten möglichst gering zu halten. Dennoch ist ein präzise geführter Lauf der Paletten unabdingbar, allein schon um den geforderten geringen Spalt seitlich zwischen Paletten und Begrenzungssockel einzuhalten.So escalators, but especially moving walks, which are often in the Run continuously and can be very long, as little as possible Consuming energy, it is important to reduce the friction already in the Keep the area of the drive of the pallets as small as possible. Nevertheless, a precisely guided run of the pallets is essential just by the required small gap on the side between pallets and delimitation base.
Zur Reduzierung der von dem Fahrsteig abgegebenen Geräusche ist es ferner bekannt geworden, die Laufrollen, d.h. sowohl die Palettenketten-Laufrollen, die Führungsrollen der Paletten als auch die Schlepprollen, über welche das gegenüberliegende Ende der Palette je geführt ist, mit Kunststoff auszurüsten. Hierdurch ergibt sich tatsächlich eine reduzierte Geräuschemission, wobei jedoch die Rollreibung von Kunststoffrollen etwas größer als diejenige von metallischen Rollen ist. Die Rollreibung von Wälzlagern, wie beispielsweise Kugellagern, ist etwas geringer als die von Gleitlagern.To reduce the noise emitted by the moving walk it has also become known to use rollers, i.e. either the pallet chain rollers, the guide rollers of the pallets as well as the drag rollers over which the opposite one End of the pallet is guided, to be equipped with plastic. This actually results in a reduced noise emission, however, the rolling friction of plastic rollers is slightly larger than that of metallic rolls. The Rolling friction of rolling bearings, such as ball bearings, is slightly less than that of plain bearings.
Daher liegt der Erfindung die Aufgabe zugrunde, einen Fahrsteig gemäß dem Oberbegriff von Anspruch 1 zu schaffen, der hinsichtlich der Laufeigenschaften verbessert ist, wobei dennoch der bauliche Aufwand reduziert ist. The invention is therefore based on the object of a moving walk according to the preamble of claim 1 to create the is improved in terms of running properties, wherein the construction effort is nevertheless reduced.
Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen von Anspruch 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by the characterizing part of claim 1. Advantageous further developments result from the subclaims.
Erfindungsgemäß ist es vorgesehen, die bislang vorhandenen Schlepprollen wegzulassen und anstelle dessen die Palette über Mitnahmeelemente unmittelbar an Palettenkettengliedern anzulenken. Überraschend lassen sich hierdurch die Laufeigenschaften verbessern, denn es sind insgesamt weniger Reibung erzeugende Rollen vorhanden. Die Führung ist verbessert, denn das Mitnahmeelement stützt sich über das zugehörige Kettenglied nicht nur auf einer, sondern auf den beiden benachbarten - ohnehin vorgesehenen - Palettenketten-Laufrollen ab, so daß diese doppelt ausgenutzt werden. In diesem Zusammenhang ist es besonders günstig, wenn das Mitnahmeelement ziemlich genau in der Mitte der Palettenkettenglieder gelagert ist, um eine gleichmäßige Belastung der beiden benachbarten Rollen zu erzielen.According to the invention, the existing ones are provided Omit drag rollers and replace the pallet instead To link driving elements directly to pallet chain links. Surprisingly, this allows the running properties improve, because there are less friction generating Roles available. The leadership is improved because that Driving element is supported by the associated chain link not just on one, but on the two neighboring ones - provided anyway - pallet chain rollers, so that these are used twice. In this context it is particularly cheap if the driving element is pretty much in the middle of the pallet chain links is supported by one to achieve uniform loading of the two adjacent roles.
Der bauliche Aufwand im Rückführungsbereich ist signifikant reduziert, denn die für Schlepprollen erforderlichen Führungsschienen können vollständig entfallen. Auch an den Umkehrstellen können zusätzliche Zwangsführungen entfallen, nachdem die Paletten im Rücklauf von den Palettenketten getragen werden. Die Höhenjustierung der Paletten zueinander ist vereinfacht, denn die Mitnahmeelemente können ziemlich kurz, massiv und spielarm gelagert sein, so daß sich bereits durch die richtige Längenwahl die automatische Höhenanpassung zueinander benachbarter Paletten ergibt.The construction effort in the return area is significant reduced because the guide rails required for drag rollers can be completely eliminated. Even at the reversal points additional forced guidance can be omitted after the Pallets in the return are carried by the pallet chains. The height adjustment of the pallets to each other is simplified, because the driving elements can be quite short, massive and be stored with little play so that it is already correct Length selection the automatic height adjustment of adjacent to each other Pallets results.
Die erfindungsgemäße Lösung bietet zudem den Vorteil, daß die Umkehrstellen einfacher aufgebaut sein können. Mit den als Lenker ausgebildeten Mitnahmeelementen wird der erforderliche Längenausgleich an den Umführungsbögen gewährleistet. Es ist bevorzugt, daß die Positionierung der Lagerstellen der Mitnahmeelemente so erfolgt, daß die Mitnahmeelemente bei gerade geführter Palette etwa 5 bis 6° nach einwärts, d.h. zur Palettenmitte hin, geneigt sind. Im Umführungsbogen sind sie dann etwa um den gleichen Betrag nach auswärts geneigt. Durch eine erforderliche Kettenspannvorrichtung werden die Palettenketten in jeder Situation gestrafft, so daß die Paletten nicht kollabieren können.The solution according to the invention also has the advantage that the Inversion points can be constructed more simply. With the as Handlebar trained driving elements becomes the required Length compensation guaranteed on the bypass bends. It is preferred that the positioning of the bearing points of the driving elements takes place so that the driving elements with just guided Pallet about 5 to 6 ° inwards, i.e. to the middle of the pallet are inclined. Then they are in the bypass tilted outward about the same amount. By a The necessary chain tensioner are the pallet chains tightened in every situation so that the pallets do not collapse can.
Besonders günstig ist es auch, daß für die Führungsrollen und die Palettenkette im übrigen auf handelsübliche Teile zurückgegriffen werden kann. Es muß lediglich jede zweite Innenlasche der Palettenkette mit einer entsprechenden Bohrung für die Aufnahme des Lagerbolzens für das Mitnahmeelement versehen sein. In an sich bekannter Weise ist der Lagerbolzen drehfest mit der Innenlasche verbunden und das Mitnahmeelement dreht sich auf dem Lagerbolzen, der somit eine große Lagerfläche mit geringer Flächenpressung bereitstellt. Aufgrund der geringen Auslenkung ist es erfindugnsgemäß besonders günstig, daß mit einfachen Gleitlagern gearbeitet werden kann, so daß teure und zusätzliches Gewicht bedingende Kugellager entbehrlich sind.It is also particularly favorable that for the guide rollers and the pallet chain also uses commercially available parts can be. It only needs every second inner flap the pallet chain with a corresponding hole for provide the mounting of the bearing pin for the driving element his. In a manner known per se, the bearing pin is non-rotatable connected to the inner plate and the driving element rotates itself on the bearing pin, which thus has a large bearing surface provides low surface pressure. Because of the low Deflection according to the invention is particularly favorable that with simple plain bearings can be worked, so that expensive and additional ball bearings are unnecessary.

Ein in Fig. 1 lediglich in Form eines kleinen Ausschnitts dargestellter
Fahrsteig 10 weist eine Palette 12 auf, die an einer
Palettenkette 14 geführt ist. Die Palette 12 läuft auf
Führungsrollen 16, die in die Palettenkette 14 integriert
sind, wie es an sich bekannt ist. Zusätzlich zu den Führungsrollen
16 weist die Palettenkette je zwei Lauf- oder Kettenrollen
18 auf, die in gleichem Abstand voneinander und von der
Führungsrolle 16 und auch der Führungsrolle 16 der nächstfolgenden
Palette beabstandet sind. Beidseitig der Palette ist je
eine Palettenkette vorgesehen, wobei in Fig. 1 nur eine Seite
dargestellt ist.One shown in Fig. 1 only in the form of a small
Die Palette 12 ist an ihrem vorderen Ende beidseitig über eine
Führungsrolle 16 und eine Hohlachse 17 an den Palettenketten
14, von denen die rechte Palettenkette 14 in Fig. 1 dargestellt
ist, abgestützt. An ihrem hinteren Ende ist die Palette
12 erfindungsgemäß auf der Palettenkette 14 abgestützt, und
zwar über Palettenstützelemente, insbesondere Palettenbolzen
20, und Mitnahmeelemente 22. Dementsprechend entfallen separate
Schienen für die Schlepprollen, die ansonsten erforderlich
wären, und alle Kettenrollen 18 und Führungsrollen 16
können auf einer gemeinsamen Schiene hintereinander laufen.The
Dies gilt gleichermaßen für den Palettenrücklauf, bei dem die
Paletten unter der Oberfläche zurückgeführt werden. Das Mitnahmeelemente
22 ist so ausgebildet, daß es nicht nur die Abstützung
im Palettenvorlauf, sondern auch die Aufhängung der
Paletten im Palettenrücklauf ermöglicht.This also applies to the pallet return, where the
Pallets can be returned below the surface. The
Die Palette 12 ist dementsprechend an vier Punkten auf den Palettenketten
14 beidseitig abgestützt und ist somit präzise
und sicher geführt.The
Wie es besser aus Fig. 2 ersichtlich ist, erstreckt sich der
Palettenbolzen 20 seitlich zu der Palettenkette 14 hin aus der
Palette 12 heraus. Die Palette ist bevorzugt aus Aluminium-Druckguß
ausgebildet und der Palettenbolzen 20 ist mit eingegossen.
Er läuft in einer Lagerausnehmung oder Bohrung 24 des
Mitnahmeelements 22, so daß das Mitnahmelement 22 um die
Achse des Palettenbolzen 20 schwenkbar ist.As can be seen better from Fig. 2, the
Pallet
Das Mitnahmeelement 22 erstreckt sich ziemlich breit über nahezu
die gesamte Breite zwischen Innenlaschen 26 der Palettenkette
14. Anstelle der Befestigung an Außenlaschen 36 ist es
bevorzugt, die Lagerung des Mitnahmelements 22 an Innenlaschen
26 vorzunehmen, nachdem diese von der Geometrie des Kettenantriebs
her besser geeignet sind. Das Mitnahmeelement 22 ist
auf der Palettenkette 14 über einen Lagerbolzen 28 schwenkbeweglich
gelagert.The
Der Lagerbolzen 28 ist an den Innenlaschen 26 drehfest und unverlierbar
gehalten, und zwar bevorzugt mittels eines in einer
Nut 30 eingebrachten, nicht dargestellten Lagerrings und einer
dargestellten Haltespange 32. Das Mitnahmeelement 22 ist auf
dem Lagerbolzen 28 schwenkbeweglich gelagert. Damit ergibt
sich eine doppelt schwenkbewegliche Lagerung des als Lenker
ausgebildeten Mitnahmeelements 22, nachdem sich beide Lagerachsen
horizontal erstrecken.The
Diese Lagerung erlaubt die Umführung der Paletten 12 störungsfrei
an den Umkehrbögen, wobei in der Fig. 1 dargestellten
waagerechten Stellung der Paletten, in welcher sie sich in der
Betriebsstellung befinden, der Palettenbolzen 20 der zugehörigen
Führungsrolle 16 der gleichen Palette 12 etwas näher ist
als der Lagerbolzen 28.This storage allows the
Damit ist das Mitnahmeelement 22 etwas zur Palettenmitte hin
geneigt, und die Schwenkbeweglichkeit ist voll ausreichend gegeben,
um der Verkürzung durch die nach der Art einer Sehne
wirkenden Palette 12 im Bereich der Umführungsbögen Rechnung
zu tragen. The
Das Mitnahmeelement 22 ist bevorzugt ziemlich klein und sehr
kompakt und massiv. Beispielsweise ist ein Achsabstand zwischen
dem Palettenbolzen 20 und dem Lagerbolzen 28 von 3 cm
völlig ausreichend. Ein möglichst kompakter Aufbau ergibt sich
bei einer Breite des Mitnahmeelements 22 zwischen den Innenlaschen
26 von ebenfalls etwa 3 cm. Das Mitnahmeelement 22 ist
damit sehr verkantungsstabil und weist eine enge Führung für
die Palette 12 auf. Dementsprechend erstreckt sich der Palettenbolzen
20 auch nur ganz knapp oberhalb der Innenlaschen 26.The
Besonders bevorzugt ist es, wenn sich der Lagerbolzen 28 etwa
in der Mitte der Innenlaschen 26 erstreckt. Dann wird etwa die
halbe Last, die auf das Mitnahmeelemente 22 wirkt, von der benachbarten
Kettenrolle 18 und die andere Hälfte der Last von
der Führungsrolle 16 der nachfolgenden Palette aufgenommen.
Überraschend ist diese Ausgestaltung besonders günstig für
einen geräuscharmen und präzisen Lauf, wenn Kunststoff- oder
Gummirollen verwendet werden.It is particularly preferred if the
Wie aus Fig. 3 ersichtlich ist, ist die Führungsrolle 16 bevorzugt
härter, besteht also aus einem härter eingestellten
Kunststoff an ihrer Oberfläche, während die Führungsrolle 18
sowie die leerlaufende, von dem Mitnahmeelemente 22 entfernte
Führungsrolle 18 aus einem weicher eingestellten Kunststoff
besteht, in dem zudem das betreffende Kugellager unmittelbar
eingebettet ist.As can be seen from Fig. 3, the
Alle Rollen, also die Führungsrollen 16 und die Kettenrollen
18 sind bei dem erfindungsgemäßen Fahrsteig 10 mit Kugellagern
34 ausgerüstet. Dies ergibt einen leichten und geräuscharmen
Lauf und eine sichere Abstützung. Die Palettenkette ist - wie
es ebenfalls aus Fig. 3 ersichtlich ist - in an sich bekannter
Weise ausgebildet, wobei sie lediglich im Bereich der Innenlaschen
26 mit Bohrungen für die Aufnahme des Lagerbolzens 28
versehen ist. All rollers, i.e. the
Es versteht sich, daß anstelle der dargestellten Ausgestaltung
des Mitnahmeelements 22 auch eine beliebige andere wählbar
ist. Bei der Ausgestaltung mit der Haltespange 32 kann die
Montage des Mitnahmeelements 22 besonders leicht erfolgen. Bei
bereits fertig montierten Paletten und Palettenketten wird das
Mitnahmeelement 22 auf den vorstehenden Palettenbolzen 20 aufgeschoben.
Das Mitnahmeelement 22 wird dann so verschwenkt,
daß der Lagerbolzen 28 durch die Bohrung in den Innenlaschen
26 eingeführt werden kann, was von außen geschehen kann, so
daß die Ausgestaltung insofern montagefreundlich ist. Nach
vollständigem Einschieben wird lediglich noch die Haltespange
32 aufgesetzt, wobei die bevorzugte Ausgestaltung eine solche
Haltespange 32 aufweist, die durch den Lagerbolzen 28 hindurchsteckbar
und in eingestecktem Zustand unverlierbar gehalten
ist.It is understood that instead of the embodiment shown
the driving
Es versteht sich, daß anstelle der dargestellten Ausführungsform
des Mitnahmelements 22 auch eine beliebige andere erfindungsgemäß
möglich ist. Beispielsweise ist eine Schiebeführung
zur Bereitstellung des Längenausgleichs möglich, so daß die
Mitnahmeelemente 22 als Führungsklammern ausgebildet sind, die
die Innenlaschen 26 beweglich umgreifen. Auch kann mit einer
anderen Palettenkette die Abstützung an einer anderen Stelle
an den Innenlaschen 26, oder aber auch an den Außenlaschen 36
oder bei Bedarf auch an dem Gelenk zwischen Innenlaschen und
Außenlaschen erfolgen. Die bevorzugte Ausgestaltung, wie sie
in den Figuren dargestellt ist, bietet jedoch eine breite und
gute Abstützung jeder Palette 12.It is understood that instead of the illustrated embodiment
the driving
Auch ist es möglich, anstelle des Lagerbolzens 28 eine Hohlachse
wie für die Führungsrolle 16 zu verwenden oder auch den
Palettenbolzen 20 entsprechend auszubilden.It is also possible to use a hollow axle instead of the bearing
