Definitions
- the invention relates to steps or pallets with special step cheeks or cheeks for driving devices according to the preamble of claim 1 and driving devices with such steps or pallets according to claim 12.
- Driving devices in the context of the invention which can also be referred to as conveyors, are escalators and moving walks with a plurality of tread units or moving-platform pallets which are connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they walk on the pavement pallets in the same direction of movement as the driving devices drive or move.
- the tread units form escalator steps, hereafter referred to as steps, and for ride surfaces, the tread units form pavement pallets, hereafter referred to as pallets.
- Escalators overcome with relatively large inclination greater differences in height as entire floors. Moving walkways, on the other hand, run horizontally or slightly at an angle, but generally with lower angles of inclination than escalators.
- such driving devices include drive trains, which are designed as stepped or pallet chains.
- drive trains are driven to move the steps or pallets in the conveying direction, and they are provided according to the prior art at equal intervals with so-called rollers.
- rollers These casters travel along dedicated or dedicated lanes Tracks.
- the drive trains run with the rollers around deflection wheels (eg sprockets) and thus make a change of direction.
- deflection wheels eg sprockets
- the sliders or rollers run or chain rollers
- the sliders or rollers are attached directly to a step chain or pallet chain that serves as a drive train, as described above.
- step or pallet chains including the sliding or rolling elements attached thereto, two further rollers are required per step or pallet, which are referred to as towing rollers and roll or drive along separate guide rails.
- the stages or pallets have been relatively expensive to manufacture or to pour and also expensive, since they must be very stable and torsionally rigid.
- the steps or pallets must be made very accurately to ensure a smooth, smooth running.
- An essential element of the steps or the pallets are the lateral cheeks or step cheeks, which have an essential supporting function. So far, step cheeks or cheeks are typically made of aluminum, which leads to a low weight, but brings high costs, since the molds or die casting molds are very expensive.
- partially step cheeks or cheeks are used, which are screwed together from several different sheet metal parts and different castings or pressed parts. These cheeks or cheeks are usually about twice as heavy as an aluminum (stepped) cheek.
- the JP 2004/292106 A describes a step for a driving device, which has side cheeks. These have a three-dimensional shape with partially encircling board.
- this document can be found in the features of the preamble of claim 1.
- Fig. 1 is in Figs. 7 and 12 of this document in the side cheeks to see a circle as Cheek eye can be interpreted.
- this circle is not designated and not explained in the description. In any case, the location of the circle excludes that a chain pin axis can be stored there.
- the JP 01308388 A or the equivalent GB 2216825 A shows in Fig. 1 a step with side cheeks, which have a two-dimensional shape and are designed without a peripheral edge.
- This formed of thick material side cheeks store in the usual way chain pin axes and tow roller axles.
- Fig. 18 side cheeks can be seen, which are formed of thin sheet with partially circumferential edge. However, these side cheeks have no eyes that could serve for the storage of chain pin axles or tow roller axles. These axles are obviously stored on more stable components that need to be connected to these cheeks.
- the DD 69443 relates to a step for escalators, wherein the side cheeks are integrally connected to a front part.
- the front part is covered by a setting element.
- a tread element covering the step has a bend which closes off the step on the side opposite the setting element.
- the front part and the cheeks are flat, in which no eyes are provided for receiving axles. Again, the axes are probably stored in more stable components that need to be connected to the cheeks.
- Step cheeks or cheeks according to the invention are specially designed for use in a driving device which have a plurality of steps or pallets, each step or pallet having two lateral step cheeks or cheeks which are substantially perpendicular to a tread element or a tread surface and in one Stage also to a setting element or a setting surface or riser.
- middle step cheeks or cheeks can also be provided between the two lateral step cheeks or cheeks.
- the step cheek or cheek consists of a one-piece, deep-drawn sheet metal, wherein the sheet has a three-dimensional shape with an at least partially encircling board.
- the step cheek or cheek on a stepped eye or pallet eye, which by Deep drawing is formed.
- the stepped eye or pallet eye of the step cheek or cheek is enclosed or surrounded by the sheet or steel sheet or NIROSTA sheet.
- the step cheek or cheek comprises with the step eye or pallet eye a chain pin axis of a chain or conveyor chain.
- An inventive driving device has at least one such step or pallet.
- a deep-drawn eye is sufficiently stable that the bearing for the chain pin axis can be accommodated therein directly.
- the production is of course much easier, but the step cheek or cheek can be made from a single part by deep drawing. Considering that the entire driving force is transmitted through these chain pin axes, this is by no means obvious.
- driving device 1 is an escalator, which connects a lower level E1 with an upper level E2.
- the driving device 1 has lateral balustrades 4 and base plates 3 and an endless conveyor with drive trains.
- drive trains are typically two mutually parallel step chains or conveyor chains with chain rollers used to enable the stages 2 in motion.
- an endless handrail 10 is provided.
- the handrail 10 moves in solidarity or slightly leading with the drive trains or chain strands and the steps 2 or pallets.
- the supporting or truss and the reference numeral 3 denotes the base plate of the driving device 1.
- the endless conveyor of the driving device 1 essentially comprises a plurality of tread units (steps 2), as well as the two laterally arranged drive trains, respectively step chains, between which the steps 2 are arranged and with which the steps 2 are mechanically connected.
- the endless conveyor comprises a drive, not shown, as well as an upper deflection 12 and a lower deflection 13, which are located in the upper or lower end region of the driving device 1.
- the steps 2 have tread elements 9 (treads).
- stages 2 are now used which, instead of the usual step cheeks, have deep-drawn stepped cheeks 20 with attached tow rollers or rollers 6.
- These rollers 6 are mechanically connected to the respective step cheeks 20 and designed so that they drive or roll in the lead area along a first guide rail 5.1, when the endless conveyor of the driving device 1 is in motion, as in Fig. 2 can be seen.
- the first guide rails 5.1 are referred to in the present context as Vorlauf arrangementsschienen to highlight their function.
- the course, respectively the position of the step chain with the chain rollers is in Fig. 2 indicated only by the line 8.
- Fig. 3A is a perspective view of a complete stage 2 with two inventive step cheeks 20.1, 20.2 shown. Seen in the direction of travel, when the steps 2 move from the plane E1 to the plane E2, the step cheek 20.1 is arranged on the right and the step cheek 20.2 on the left of the tread element 9.
- Each step cheek 20.1, 20.2 has a drag roller 6.1, 6.2 and a chain axle 21.1, 21.2.
- the step cheek 20.1 and 20.2 is at least one central recess 29, or breakthrough, available.
- This sheet metal plate 26 extends substantially perpendicular to the surface of the step cheek 20.1 and the step cheek 20.2.
- the sheet metal shelf 26 does not necessarily have to run along the entire step cheek 20.1 or 20.2. He can only partially or be available in sections. Good to see the rotating sheet metal 26 in the Figures 4B and 5D ,
- the substructure includes, in addition to the aforementioned step cheeks 20.1 and 20.2, for example, also a rear cross member 22, a front cross member 24 and a middle side member 23 (center support or center support). These carriers 22, 23, 24 may be made of deep-drawn sheet metal.
- the support and the step cheek together form the substructure of the step or the so-called support frame or the support frame.
- the tread element 9 and the setting element 14 are attached.
- Fig. 3B Further details of the substructure or the support frame can be seen.
- the carriers 22, 23, 24 and the step cheeks 20.1, 20.2 are welded together or riveted or connected or screwed or glued or clinched. Preferably spot welds are made to connect these support elements or components or elements with each other.
- FIGS. 4A and 4B Further details of a left step cheek 20.2 can be seen.
- the step cheek 20.2 is "equipped" with all elements and can be incorporated or welded in the form shown in the substructure. It can be seen that in the region of a stepped eye 32 (also referred to as chain pin eye) a chain pin axle 21.2 or chain roller axle 21.2 is inserted or inserted.

Description
Die Erfindung betrifft Stufen bzw. Paletten mit speziellen Stufenwangen bzw. Wangen für Fahreinrichtungen nach dem Oberbegriff des Anspruchs 1 und Fahreinrichtungen mit solchen Stufen bzw. Paletten gemäß Anspruch 12.The invention relates to steps or pallets with special step cheeks or cheeks for driving devices according to the preamble of
Fahreinrichtungen im Sinne der Erfindung, die auch als Fördereinrichtungen bezeichnet werden können, sind Fahrtreppen und Fahrsteige mit einer Vielzahl von Tritteinheiten oder Fahrsteigpaletten, die zu einem Endlosförderer verbunden sind. Benutzer der Fahreinrichtungen stehen auf Trittflächen der Tritteinheiten oder sie gehen auf den Fahrsteigpaletten in gleicher Bewegungsrichtung, wie die Fahreinrichtungen fahren bzw. sich fortbewegen.Driving devices in the context of the invention, which can also be referred to as conveyors, are escalators and moving walks with a plurality of tread units or moving-platform pallets which are connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they walk on the pavement pallets in the same direction of movement as the driving devices drive or move.
Bei Fahrtreppen bilden die Tritteinheiten Fahrtreppenstufen, im Weiteren als Stufen bezeichnet, und bei Fahrsteigen bilden die Tritteinheiten Fahrsteigpaletten, im Weiteren als Paletten bezeichnet. Fahrtreppen überwinden mit relativ grossem Neigungswinkel grössere Höhenunterschiede wie ganze Stockwerke. Fahrsteige hingegen verlaufen horizontal oder leicht schräg, aber im Allgemeinen mit geringeren Neigungswinkeln als Fahrtreppen.For escalators, the tread units form escalator steps, hereafter referred to as steps, and for ride surfaces, the tread units form pavement pallets, hereafter referred to as pallets. Escalators overcome with relatively large inclination greater differences in height as entire floors. Moving walkways, on the other hand, run horizontally or slightly at an angle, but generally with lower angles of inclination than escalators.
Typischerweise umfassen solche Fahreinrichtungen Antriebsstränge, die als Stufen- oder Palettenketten ausgebildet sind. Im Folgenden ist der Einfachheit halber lediglich von Antriebssträngen die Rede. Diese Antriebsstränge werden angetrieben, um die Stufen oder Paletten in Förderrichtung zu bewegen, und sie sind gemäss Stand der Technik in gleichmässigen Abständen mit so genannten Laufrollen versehen. Diese Laufrollen fahren bzw. rollen entlang von dedizierten bzw. vorgesehenen Laufschienen. Im Bereich der Enden der Fahreinrichtungen laufen die Antriebsstränge mit den Laufrollen um Umlenkräder (z.B. Kettenräder) herum und vollziehen so einen Richtungswechsel. Anstatt der Laufrollen oder Kettenrollen können auch Gleitelemente eingesetzt werden. Die Gleitelemente oder die Rollelemente (Lauf- oder Kettenrollen) sind unmittelbar an einer Stufenkette oder Palettenkette befestigt, die als Antriebsstrang dient, wie weiter oben beschrieben wurde.Typically, such driving devices include drive trains, which are designed as stepped or pallet chains. In the following, for the sake of simplicity, only drive trains are mentioned. These drive trains are driven to move the steps or pallets in the conveying direction, and they are provided according to the prior art at equal intervals with so-called rollers. These casters travel along dedicated or dedicated lanes Tracks. In the area of the ends of the driving devices, the drive trains run with the rollers around deflection wheels (eg sprockets) and thus make a change of direction. Instead of the rollers or chain rollers and sliding elements can be used. The sliders or rollers (run or chain rollers) are attached directly to a step chain or pallet chain that serves as a drive train, as described above.
Zusätzlich zu den Stufen- oder Palettenketten samt der daran befestigten Gleit- oder Rollelemente sind pro Stufe bzw. Palette zwei weitere Rollen erforderlich, die als Schlepprollen bezeichnet werden und entlang separater Führungsschienen rollen bzw. fahren.In addition to the step or pallet chains, including the sliding or rolling elements attached thereto, two further rollers are required per step or pallet, which are referred to as towing rollers and roll or drive along separate guide rails.
Die Stufen bzw. Paletten sind bisher relativ aufwendig zu fertigen bzw. zu gießen und auch teuer, da sie in sich sehr stabil und verwindungssteif sein müssen. Ausserdem müssen die Stufen bzw. Paletten sehr genau gefertigt sein, um einen ruhigen, ruckfreien Lauf zu garantieren. Ein wesentliches Element der Stufen bzw. der Paletten sind die seitlichen Wangen bzw. Stufenwangen, die eine wesentliche Tragfunktion haben. Bisher werden Stufenwangen bzw. Wangen typischerweise aus Aluminium gefertigt, was zwar zu einem geringen Gewicht führt, aber hohe Kosten mit sich bringt, da die Gussformen bzw. Druckgussformen sehr teuer sind. Als Alternative kommen teilweise Stufenwangen bzw. Wangen zum Einsatz, die aus mehreren unterschiedlichen Blechteilen und verschiedenen Guss- bzw. Pressteilen zusammengeschraubt werden. Diese Stufenwangen bzw. Wangen sind üblicherweise ungefähr doppelt so schwer wie eine Aluminium(stufen)wange.The stages or pallets have been relatively expensive to manufacture or to pour and also expensive, since they must be very stable and torsionally rigid. In addition, the steps or pallets must be made very accurately to ensure a smooth, smooth running. An essential element of the steps or the pallets are the lateral cheeks or step cheeks, which have an essential supporting function. So far, step cheeks or cheeks are typically made of aluminum, which leads to a low weight, but brings high costs, since the molds or die casting molds are very expensive. As an alternative partially step cheeks or cheeks are used, which are screwed together from several different sheet metal parts and different castings or pressed parts. These cheeks or cheeks are usually about twice as heavy as an aluminum (stepped) cheek.

Besonders für eine kostengünstigere Erstausrüstung von Fahreinrichtungen besteht der Wunsch, die Stufen und Paletten durch günstigere Teile zu ersetzen, ohne dabei jedoch die Laufruhe, die Fahreigenschaften, die Stabilität, die Robustheit und die Zuverlässigkeit sowie die Standfestigkeit zu beeinträchtigen. Ausserdem soll der Herstellungsprozess vereinfacht und beschleunigt werden.Especially for a more cost-effective original equipment of driving equipment is the desire to replace the steps and pallets with cheaper parts, but without compromising smoothness, ride quality, stability, robustness and reliability and stability. In addition, the manufacturing process should be simplified and accelerated.
Aufgabe der Erfindung ist es daher,
- eine kostengünstigere Stufenwange bzw. Wange für eine Stufe bzw. Palette der eingangs genannten Art zu schaffen, die aber trotzdem sämtlichen Anforderungen bzw. Änforderungsprofilen genügt und einen ruhigen, ruckfreien Lauf ermöglicht, nicht störungsanfällig ist und eine lange Laufzeit bzw. hohe Lebensdauer garantiert. Ausserdem sollen die Wangen bzw. Stufenwangen nicht wesentlich schwerer sein als die gängigen Aluminium(stufen)wangen;
- eine kostengünstigere Fahreinrichtung der eingangs genannten Art zu schaffen, die einen ruhigen, ruckfreien Lauf ermöglicht, nicht störungsanfällig ist und eine hohe Lebensdauer bzw. lange Laufzeit garantiert.
- To create a cheaper stage cheek or cheek for a level or range of the type mentioned, but still satisfies all requirements or Änforderungsprofilen and allows a smooth, smooth running, is not prone to failure and a long life or long service life guaranteed. In addition, the cheeks or step cheeks should not be much heavier than the standard aluminum (stages) cheeks;
- to provide a cheaper driving device of the type mentioned above, which allows a smooth, smooth running, is not prone to failure and guarantees a long life and long life.
Diese Aufgabe wird erfindungsgemäss gelöst durch die Merkmale des Anspruchs 1 und die Merkmale des Anspruchs 12.This object is achieved according to the invention by the features of
Erfindungsgemässe Stufenwangen bzw. Wangen sind speziell für den Einsatz in einer Fahreinrichtung ausgelegt, die mehrere Stufen oder Paletten aufweisen, wobei jede Stufe oder Palette zwei seitliche Stufenwangen bzw. Wangen hat, die im Wesentlichen senkrecht stehen zu einem Trittelement bzw. einer Trittfläche und bei einer Stufe auch zu einem Setzelement bzw. einer Setzfläche bzw. Setzstufe. Zwischen den beiden seitlichen Stufenwangen bzw. Wangen können natürlich auch noch mittlere Stufenwangen bzw. Wangen vorgesehen sein. Die Stufenwange bzw. Wange besteht aus einem einstückigen, tiefgezogenen Blech, wobei das Blech eine dreidimensionale Form mit einem mindestens teilweise umlaufenden Bord hat. Ausserdem weist die Stufenwange bzw. Wange ein Stufenauge bzw. Palettenauge auf, welches durch Tiefziehen ausgebildet ist. Darüber hinaus ist das Stufenauge bzw. Palettenauge der Stufenwange bzw. Wange von dem Blech bzw. Stahlblech bzw. NIROSTA-Blech umschlossen bzw. umgeben. Die Stufenwange bzw. Wange umfasst mit dem Stufenauge bzw. Palettenauge eine Kettenbolzenachse einer Kette bzw. Förderkette.Step cheeks or cheeks according to the invention are specially designed for use in a driving device which have a plurality of steps or pallets, each step or pallet having two lateral step cheeks or cheeks which are substantially perpendicular to a tread element or a tread surface and in one Stage also to a setting element or a setting surface or riser. Of course, middle step cheeks or cheeks can also be provided between the two lateral step cheeks or cheeks. The step cheek or cheek consists of a one-piece, deep-drawn sheet metal, wherein the sheet has a three-dimensional shape with an at least partially encircling board. In addition, the step cheek or cheek on a stepped eye or pallet eye, which by Deep drawing is formed. In addition, the stepped eye or pallet eye of the step cheek or cheek is enclosed or surrounded by the sheet or steel sheet or NIROSTA sheet. The step cheek or cheek comprises with the step eye or pallet eye a chain pin axis of a chain or conveyor chain.
Eine erfindungsgemässe Fahreinrichtung hat zumindest eine derartige Stufe bzw. Palette.An inventive driving device has at least one such step or pallet.
Überraschenderweise wurde im Rahmen der vorliegenden Erfindung gefunden, dass ein tiefgezogenes Auge ausreichend stabil ist, dass darin direkt das Lager für die Kettenbolzenachse untergebracht werden kann. Dadurch wird die Herstellung natürlich ganz wesentlich erleichtert, kann doch die Stufenwange bzw. Wange aus einem einzigen Teil durch Tiefziehen hergestellt werden. Bedenkt man, dass die gesamte Antriebskraft über diese Kettenbolzenachsen übertragen wird, ist dies keineswegs nahe liegend. Gegebenenfalls kann man das Auge durch ein Schließblech verstärken, aber dies ist immer noch wesentlich einfacher als die Achse in einem zusätzlichen, stabilen und damit schweren Bauteil zu lagern, der dann mit der Wange fest verbunden werden muss.Surprisingly, it has been found within the scope of the present invention that a deep-drawn eye is sufficiently stable that the bearing for the chain pin axis can be accommodated therein directly. As a result, the production is of course much easier, but the step cheek or cheek can be made from a single part by deep drawing. Considering that the entire driving force is transmitted through these chain pin axes, this is by no means obvious. Optionally, you can reinforce the eye by a strike plate, but this is still much easier than the axle to store in an additional, stable and thus heavy component, which then has to be firmly connected to the cheek.
Besonders verblüffend ist, dass dies selbst dann möglich ist, wenn die Kettenbolzenachse eine Kettenbolzensteckachse ist bzw. die Kettenbolzenachsen nicht durchgehend über die gesamte Breite der Fahrtreppe bzw. des Fahrsteiges sind. In diesem Fäll wirken nämlich nicht nur die Vortriebskräfte, sondern auch ganz erhebliche Torsionskräfte auf die Wangenaugen ein, liegen doch die Wangenaugen deutlich innerhalb der beiden Antriebsstränge.It is particularly surprising that this is possible even if the chain pin axis is a chain pin plug axis or the chain pin axes are not continuous over the entire width of the escalator or the moving walk. In this case, not only the propulsive forces, but also very considerable torsional forces act on the cheeks eyes, since the cheeks' eyes lie clearly within the two drive trains.
Bevorzugte Weiterbildungen der erfindungsgemässen Stufenwange bzw. Wange und der Fahreinrichtung sind durch die abhängigen Ansprüche definiert. Insbesondere soll erwähnt werden, dass es natürlich günstig ist, auch die Schlepprollenachsen analog zu befestigen.Preferred developments of the inventive step cheek or cheek and the driving device are defined by the dependent claims. In particular, it should be mentioned that it Of course, it is favorable to attach the tow axles analogously.

Weiters wird der Stufenwange ausreichende Stabilität verliehen, indem zusätzliche Ausformungen 28 sowie zusätzliche Sicken 28 vorhanden sind. Auch der Blechbord 26 verleiht dem dünnen Tiefziehblech sehr hohe bzw. sehr große Stabilität.Furthermore, the step cheek is given sufficient stability by having
Vorzugsweise wird ein H380 oder H400 Tiefziehblech bzw. Blech verwendet, wobei die Zahlen 380, bzw. 400 die Streckgrenze in N/mm2 angeben. Besonders geeignet sind diese Bleche, weil eine Zug-Bruchgrenze von mindestens 900 N/mm2 gegeben ist. Darüber hinaus ist besonders vorteilhaft wenn die Bleche eine Zug-Bruchgrenze von mindestens 1100 N/mm2 aufweisen.Preferably, a H380 or H400 thermoforming sheet or sheet is used, wherein the numbers specify 380 or 400, the yield strength in N / mm 2 . These sheets are particularly suitable because a tensile breaking strength of at least 900 N / mm 2 is given. In addition, it is particularly advantageous if the sheets have a tensile breaking strength of at least 1100 N / mm 2 .
Das verwendete Tiefziehblech hat vorzugsweise eine Dicke zwischen 0,9 mm und 1,9 mm. Besonders bevorzugt ist eine Dicke von 1,5 bis 1,8 mm.The deep drawing sheet used preferably has a thickness between 0.9 mm and 1.9 mm. Particularly preferred is a thickness of 1.5 to 1.8 mm.
Falls das Tiefziehblech entsprechend der obigen Angaben gewählt wird, dann erfüllen die Stufenwangen, respektive die Stufe(n) alle Belastungstests der Norm EN 115: Sicherheitsregeln für die Konstruktion und den Einbau von Fahrtreppen und Fahrsteigen, sowie der AN - American National Standard - ASME A17.1-2004: Safety code for elevators and escalators.If the thermoforming sheet is chosen according to the above information, then the step cheeks, respectively the step (s), will comply with all EN 115: Safety rules for the construction and installation of escalators and moving walkways, as well as the AN - American National Standard - ASME A17 .1-2004: Safety code for elevators and escalators.
Vorzugsweise weist das Tiefziehblech eine Oberflächenbeschichtung auf. Besonders bevorzugt sind Oberflächenbeschichtungen, die durch Tauchlackieren erzeugt werden.Preferably, the deep-drawn sheet has a surface coating. Particularly preferred are surface coatings which are produced by dip coating.
Besonders geeignet ist das kathodische Tauchlackieren (KTL).Particularly suitable is the cathodic dip coating (KTL).
Das Ergebnis der KTL ist eine sehr gleichmäßige Beschichtung des Tiefziehblechs mit gleichmäßigen Schichtdicken und guten Oberflächenqualitäten. Nach der KTL- Behandlung weist das Tiefziehblech eine gleichmässige, durchgehende Lackschicht auf. Besonders gute Ergebnisse werden erzielt, wenn die KTL-Behandlung nach dem Tiefziehen des Blechs angewendet wird.The result of the KTL is a very uniform coating of the deep-drawn sheet with uniform layer thicknesses and good surface qualities. After the KTL treatment, the deep-drawn sheet has a uniform, continuous lacquer layer. Particularly good results are achieved when the KTL treatment is applied after deep drawing of the sheet.
Es ist auch eine Anwendung der KTL- Behandlung vor dem Tiefziehen denkbar. Weiter ist auch ein Gebrauch bzw. eine Anwendung mit (vor)verzinkten Blechen oder NIROSTA-Blechen oder Kupferblechen machbar.It is also an application of the KTL treatment before thermoforming conceivable. Furthermore, a use or an application with (before) galvanized sheets or NIROSTA sheets or copper sheets is feasible.
Wie beschrieben, lässt sich die Erfindung auf Fahrtreppen und Fahrsteige anwenden.As described, the invention can be applied to escalators and moving walks.
