Description

Technical area

The present invention relates to a method for producing a component of a guideway device, in particular an escalator device. Furthermore, the present invention relates to a component of a guideway device produced according to such a method and to a guideway device with such a component.

Background of the invention

Guideway devices, in particular escalator devices, are generally known from the prior art. In such guideway devices, support structures form the outer supporting structure for components of the guideway device, such as guides with steps/pallets embedded therein, drives and electrical systems as well as for attachment and cladding elements, and are usually made up of two side wall units that are opposite one another and connected via cross beams. The side wall units usually have profiles welded to one another as structural elements, from which lattice-like side walls and an upper and lower chord are formed.

The disadvantage is that welding is very labor intensive. In addition, the support structures described above have relatively large manufacturing tolerances, which are caused in particular by the welding of the profiles. Components of the guideway device that are attached to the support structure must therefore be positioned and/or aligned using very complex positioning processes with appropriate assembly aids before they are attached to the support structure. For this purpose, appropriate fastening means are designed for variable positioning/alignment of the component in relation to the support structure and/or must be created manually after positioning and/or alignment, which is a laborious process.

Out of EP 1 321 424 B1 A supporting structure for an escalator or moving walkway is known, which has a lattice element that is designed as a single piece and as a flat, unprofiled, cut plate. The welding work required to build the supporting structure is thus reduced.

Description of the invention

Based on this situation, it is an object of the present invention to enable a simplified and safe positioning/alignment of components of a guideway device and in particular to reduce the workload in the manufacture of a guideway device.

The object of the invention is achieved by the features of the independent main claims. Advantageous embodiments are specified in the subclaims. If technically possible, the teachings of the subclaims can be combined as desired with the teachings of the main and subclaims.

In particular, the object is accordingly achieved by a method for producing a component of a guideway device, in particular an escalator device, wherein at least one recess is formed on at least one element of the component by means of a laser cutting tool, wherein before, during or after the formation of the at least one recess, at least one piece of information for carrying out a weld seam is applied/introduced to the element by means of the laser cutting tool, and wherein the element is connected to other elements of the component and/or other components of the guideway device by carrying out the weld seam in accordance with the applied/introduced information.

It is preferred that the order of process steps can be varied, unless technically required in an explicit order. However, the above-mentioned order of process steps is particularly preferred.

Advantageous aspects of the claimed invention are explained below and preferred modified embodiments of the invention are described further below. Explanations, in particular regarding advantages and definitions of features, are basically descriptive and preferred, but not limiting examples. If an explanation is limiting, this is expressly mentioned.

In the sense of the present disclosure, the general term "guideway device" refers primarily to escalator devices and moving walkway devices (the latter in particular in a stepless design in an at least approximately flat alignment or with a negligible gradient) as well as related passenger transport devices with a continuously rotating transport device. A guideway device comprises, for example, segments or units forming the transport device, in particular steps or pallets, which are connected to driven chains or comparable drive means and guided in guides. The guides as well as a/the chain (or a comparable traction device) and other components of the guideway device are held, for example, within support structures extending longitudinally essentially laterally therefrom, which are usually formed from two side wall units lying opposite one another and connected to one another via crossbeams and optionally also a floor unit. The term "guideway device" also refers in particular to modularly constructed guideway devices which are modularly constructed from several longitudinal sections or longitudinal section modules, each with an individual or individually created support structure, and which can be assembled/mounted in modules.

The supporting structure of the guideway device or the respective module is preferably formed essentially by opposing side wall units and cross members (also referred to as crossbars) connecting them, wherein a respective side wall unit is formed by at least one side wall and in particular by an upper flange and/or a lower flange. The modular manufacturing process described here can also include the connection of a base unit to the side wall units, but it has been shown that such a base unit does not necessarily have to fulfill a supporting function, but is designed, for example, with regard to the function of collecting oil from a/the drive and, if necessary, or is designed in an optimized manner with regard to coverage and/or accessibility from below to the supporting structure or the guideway device; in this respect, the floor unit is to be understood as an optional structural unit which can also be functionally provided separately from the supporting structure, but which can optionally also take on an additional supporting load-bearing function if desired in individual cases.

The term "side wall" refers to a side structure that, for example, runs flat in only one side plane at least in sections, but is alternatively or additionally formed and/or reinforced at least in sections by profiles, struts or supports that extend beyond one/the side plane. In general, the side wall is made up of structural elements or structural sections that, as flat structural sections, absorb forces in several directions and/or, as rod-shaped or strut-like structural elements/sections, absorb the respective forces only along the longitudinal extension specified by the orientation (tension or compression). The side wall is therefore designed, for example, as a closed surface, as a pure framework or as a structure with parts of closed surfaces and parts with a framework structure. Optionally, at least some of the structural elements/sections of the side wall are made of flat material, in particular sheet metal, e.g. structurally flat sections or stiffening (in particular) curved L- or U-profile sections in the area of welded connections to other structural elements/sections.

According to the understanding of the present disclosure, a "side wall unit" comprises the side wall described above and belts assigned to this side wall as further structural elements/sections, in particular an upper belt and a lower belt, wherein the belts can be formed integrally with the side wall, integrated or separate from one another. These belts are alternatively also referred to as bands. The respective side wall/unit can also be understood as a side wall/unit provided in modules, depending on the reference to a/the respective phase of the manufacturing process of the individual modules or the entire guideway device. In this respect, the term side wall unit can refer to the entire side structure comprising the upper and lower belts, and the term side wall can refer to the side structure arranged between the upper and lower belts.

The terms upper chord and lower chord, which are also referred to together as belts, refer to structural elements or structural sections extending longitudinally in the area of an upper edge or a lower edge of the side wall for absorbing loads in the longitudinal direction of the guideway device, in particular bending loads, which primarily lead to tensile stresses in the lower chord and to compressive stresses in the upper chord. The belts are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles or hollow profiles, and thus have a favorable area moment of inertia for absorbing the bending loads. The belts therefore stiffen the support structure and form outer corner points, with the belts and/or the side walls optionally serving to attach further components of the guideway device. The belts can also be designed as components separate from the side wall; however, at least some of the belts are preferably formed integrally with the side wall, for example by bending the side wall. The upper chord is particularly preferably designed as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two more of the walls being formed by a flat material component that is also L-shaped and separate from the side wall. The lower chord is also preferably designed in a similar way as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two walls being formed by the base unit that is also L-shaped and made from flat material in this area. The components forming the walls are preferably welded to one another. The upper chord and/or the lower chord can also be provided entirely in one piece with the side wall or entirely separately from the side wall (particularly in the sense of a process variation).

The general term "components" refers to all parts of the respective guideway devices, in particular the supporting structure, the side wall unit, a side wall, an upper chord, a lower chord, a structural post and elements to be mounted in the supporting structure of the guideway device or the respective modules of the guideway device, e.g. relating to electrics, drive, guidance, attachment/cladding elements or the like.

A structural post is, for example, a structural element that runs along the side wall in a vertical direction and is preferably arranged at recurring intervals along the longitudinal extension of the side wall. In particular, the structural post serves to stiffen the side wall or the support structure and/or to support loads on the side wall or the support structure. For example, a support element for supporting components on the support structure extends vertically from the side wall and forms a structural post designed as a hollow profile with an L-angle welded to the support element and the side wall. For this purpose, the side wall, the support element and/or the L-angle each have recesses and projections that engage with one another for positioning.

An element of a component is, for example, the component itself, in particular insofar as the component is formed in one piece. An element is also, for example, one of several parts from which a component is composed, in particular from a bent or non-bent flat material. For example, this is a part of a belt or a part of a structural post, such as an L-shaped bent flat material component of a belt as described above, an L-angle of the structural post, a support element and/or the side wall. Furthermore, for example, the element can also be a profile forming a belt, in particular a hollow profile.

If a recess is formed by means of laser cutting or by means of a laser cutting tool, the material is severed by a correspondingly aligned and designed laser beam. A (corresponding) laser cutting tool is designed in particular for processing from one direction, with a laser head aligned perpendicular to the workpiece and designed to be movable relative to the workpiece in a plane parallel to the workpiece. The laser cutting tool is then preferably intended for processing flat material, with the laser head also being able to be aligned in a manner deviating from its vertical orientation. A laser cutting tool can also comprise a laser head that is spatially movable around a workpiece, in particular the profile, with the profile being particularly advantageously cut from any spatial direction and independently of the Recesses can be made in the geometry of the profile. It is also possible to make recesses in a wall of a profile with opposing walls, such as a hollow profile, without the laser beam damaging the wall behind the wall in its direction. Laser cutting of profiles with opposing walls, particularly hollow profiles, is also known as tube laser cutting. If information is to be applied to the surface of an element by means of laser cutting, the laser is preferably set in such a way that it only affects the material of the element superficially.

Insofar as the element is connected to another element of the component and/or other components of the guideway device by carrying out the weld seam, the elements/components are preferably first positioned on one another by means of corresponding shapes of the elements/components. In particular, one element/component has a recess, in particular a slot, and the other element/component has a projection for engaging in the recess.

The solution to the problem with the aforementioned method now includes the teaching that a component of the guideway device is manufactured from elements with laser-cut recesses, the recesses serving as references when assembling/positioning the elements/components on each other. In this way, particularly dimensionally accurate components are provided, so that it is possible to use these components or recesses therein as references for positioning on other components or for positioning other components on the component itself. Furthermore, the disclosure is based on the teaching that, during processing on a laser cutting tool for the subsequent welding of the dimensionally accurately manufactured elements/components, information for carrying out the weld seam is already applied/introduced to the element. The additional effort required for this during processing with the laser cutting tool remains low and the significant advantage is achieved that during the subsequent welding work, the information can be recognized particularly easily directly on the element and, in the best case, no further consultation of corresponding documentation is necessary or a particularly reliable assignment of the welding point to the correct documentation. This means that the assignment of welding information to a specific weld seam is made much easier during the necessary welding work and welding can therefore be carried out more quickly and with less error.

The present disclosure is based in particular on the concept that at least a significant portion of the side walls, which defines the overall shape, is made of flat material, in particular sheet metal, wherein at least one reference point is defined on the flat material by means of laser cutting. Due to the very small tolerances typical for laser cutting, reference can be made to this at least one reference point in the further course of assembly of the guideway device, so that assembly can be carried out with very small assembly tolerances and the guideway device can be manufactured with advantageously high dimensional accuracy. In this way, the comparatively exact relative or absolute positioning of individual components of the guideway device with respect to the at least one reference point is also made possible and measures beyond referencing for aligning and positioning the components, in particular relative to one another and in particular with assembly aids, can largely be dispensed with. In particular, the invention includes the teaching of introducing further references, in particular corresponding recesses (in the sense of additional component-specific assembly reference points) into the flat material in addition to the at least one reference point arranged in particular in the corresponding side wall during the same processing method, at which further components can be arranged directly and thus in a defined position relative to at least one (master) reference point with high accuracy. The references are also introduced in particular in areas of the flat material which can be subjected to further processing steps, in particular bending processes, following the aforementioned processing method, whereby the referencing concept described here can also be implemented for multi-dimensional positioning in space with respect to at least two or all three spatial directions. The described referencing system with side walls made of flat material also has the advantage of creating a particularly light support structure compared to the usual truss construction.

In one embodiment, the at least one piece of information is applied to a surface of the element by means of laser engraving, in particular as a black engraving. In this way, it is possible to apply a wide variety of information, in particular characters, codes or the like, directly in the area of the relevant welding point without significantly damaging/weakening the material. During welding, the information can then be easily read or scanned and can therefore be recorded and implemented quickly and safely by a person carrying out the welding work.

In a further preferred embodiment, at least one piece of information is introduced by contouring an edge of the element intended for welding. For example, an edge intended for providing a weld seam is visibly contoured, or the edge is formed by alternating projections and recesses, so that only the projections rest against the other element/component and the intended weld seam only extends along the projections. Furthermore, the edge can have a chamfer in areas intended for a weld seam, so that the weld seam or seam material can be introduced in a free space created between the chamfer and the other element/component.

The element is preferably made of a flat material, in particular a metal sheet. Such a flat material can be processed particularly easily, quickly and with great precision using laser cutting. The flat material can be used, for example, to form a belt, a support element, a cross member, a side wall and/or a structural section/structural element of the side wall, such as a structural post. Alternatively, the element is made of a profile, in particular a hollow profile. The laser cutting is then carried out, for example, as tube laser cutting. Even with a profile, processing using laser cutting is possible easily, quickly and with great precision. In particular, the profile is intended to form an upper belt or lower belt.

Furthermore, the information preferably comprises at least one character and/or a code, in particular a QR code. In particular, the code is a computer-readable code. A person carrying out the welding work can then take the information directly from the element or capture it with a corresponding scanning device, so that, for example, further information for carrying out the associated weld seam is displayed on a monitor. In the latter way, it is particularly possible to display extensive information on the monitor without the information applied to/applied to the element having to be correspondingly extensive. The impairment of the element by the information applied to/applied is therefore advantageously minimal.

The information particularly preferably consists of at least part of a welding process specification. In this respect, for example, properties of the weld seam, properties of the material of the elements/components and/or properties of a welding process to be carried out.

Particularly preferably, the information consists of at least one position marking for positioning the weld seam. The positioning of the weld seam represents central information that should be continuously available to the person carrying out the weld seam while the weld seam is being carried out, so that work can be carried out without interruption. If the position marking is applied to/incorporated into the element, it can be arranged in the field of vision of the person carrying out the welding during the welding process.

The position marking is particularly preferably arranged in the immediate area of the intended weld seam, so that the position marking is changed when the weld seam is carried out. In particular, the position marking extends over the entire length of the intended weld seam. It is then possible to check whether the weld seam has been completely carried out, namely by checking the position marking for changes along its entire length. In the simplest case, the position marking is designed as a lasered line along the intended weld seam, which is passed through the weld seam. is destroyed. The position marking can also be designed as a contour of an edge along the extension of the intended weld seam.

The object is further achieved by a component of a guideway device, in particular an escalator device, wherein the component is manufactured according to a method described above. The component can be manufactured with the advantages described above with regard to the method and is therefore simple, safe and requires little work.

The component is preferably designed, for example, as an upper chord, lower chord, side wall, structural post, floor unit or cross member. In particular, elements are welded together to form profiles. Furthermore, for example, the component is designed as a side wall unit, having an upper chord, a lower chord, and a side wall extending between the upper chord and the lower chord. In particular, the side wall unit is designed in the manner of a plug-in system with recesses and projections, with elements being welded together after being plugged together. Furthermore, for example, the component is designed as a longitudinal section module of a modularly assembled guideway device, having a support structure with two side wall units lying opposite one another and connected via at least one cross member.

The object is ultimately also achieved by a guideway device, in particular an escalator device, having at least one component described above. The guideway device has the advantages described above with regard to the component.

Detailed description of the drawings

The described embodiments are merely examples that can be modified and/or supplemented in many ways within the scope of the claims. Each feature described for a specific embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a specific claim category can also be used in a corresponding manner in an embodiment of another claim category.

The Figures 1a to 1c show several longitudinal section modules 1.1, 1.2, 1.3 of a modularly assembled guideway device 1, namely Figure 1a a first longitudinal section module 1.1 designed as a lower head module, Figure 1b a second longitudinal section module 1.2 designed as an intermediate module and Figure 1c a third longitudinal section module 1.3 designed as an upper head module. The head modules extend beyond bends or have a bent stub. The longitudinal section modules 1.1, 1.2, 1.3 each have a support structure 2 with two side wall units 2.1, 2.2 extending mainly in a longitudinal direction L and cross beams 2.3 extending in a transverse direction Q. Each side wall unit 2.1, 2.2 in turn has a side wall 3, an upper flange 4.1 extending in the longitudinal direction L and a lower flange 4.2 extending in the longitudinal direction L.

The structure of the supporting structures 2 is in the Figure 1d shown in detail. The side wall 3 is made of a flat material in which structural sections 6.1 and structural sections 6.2 are formed by recesses 5. The structural sections 6.1 divide the side wall 3 or the side wall unit 2 into fields. Furthermore, structural posts 7 with support elements 11 arranged thereon and the cross struts 2.3 are arranged or fastened, in particular welded, to the structural sections 6.1.

The side wall 3 is also formed integrally with the upper flange 4.1 and the lower flange 4.2. Thus, a first wall 8.1 is formed by the flat material forming the side wall 3 and a second wall 8.2 of the upper flange 4.1 is bent in an L-shape from the first wall 8.1. A third wall 8.3 and a fourth wall 8.4 of the upper flange 4.1 are formed by a further element made from an L-shaped bent flat material and welded to the flat material forming the side wall 3. In the same way, a first wall 9.1 is formed by the flat material forming the side wall 3 and an L-shape bent from the side wall 3 and a second wall 9.2 of the lower flange 4.2 is bent in an L-shape from the first wall 9.1. A third wall 9.3 and a fourth wall 9.4 of the lower chord 4.2 are connected by an L-shaped bent floor unit 10 The elements of the upper chord 4.1 and the lower chord 4.2 are formed in particular according to a method according to the invention and have recesses and projections that correspond to one another.

Again with reference to the Figures 1a to 1c The longitudinal section modules 1.1, 1.2, 1.3 are shown with several components of the guideway device. The lower head module ( Fig. 1a ) a comb plate 12, a base 13, a balustrade 16 with a handrail 17 arranged thereon and several guides 14.1, 14.2, 14.3 for chain rollers, step/pallet rollers and/or a handrail (not shown). Corresponding guides 14.1, 14.2, 14.3, a base 13 and a balustrade 16 are also arranged in the intermediate module (Fig.lb). The guides 14.1, 14.2, 14.3 rest on the support elements 11. The upper head module ( Fig. 1c ) has, in addition to the components already present in the lower head module and/or intermediate module, a drive 15 for driving a chain and/or a handrail circuit. In the illustration of the upper head module, a balustrade 16 provided is not shown.

The longitudinal modules 1.1, 1.2, 1.3 each have reference points 18 on the supporting structures 2, or side wall units 2.1, 2.2, or side walls 3 in the flat material, which in Fig. 1d are shown. In the Figures 1a to 1c the reference points 18 are covered by mounting brackets 19, which in turn are attached to slides 20. By hanging the longitudinal sections 1.1, 1.2, 1.3 on the reference points 18, it is possible to refer to the reference points 18 again and again during assembly and, ideally, only when positioning/aligning components. The reference points 18 are formed on the flat material by laser cutting during the manufacture of the side walls 3, whereby, due to the precision typical for laser cutting, all other recesses or cutouts made in the flat material are positioned exactly opposite the reference points 18 and can therefore serve as references when positioning/aligning components. This applies in particular to connecting means 21 and slots 22 provided for connecting the longitudinal section modules 1.1, 1.2, 1.3 for receiving components of the guideway device 1 such as the support elements 11. By means of the reference points 18 and in particular the suspension of the longitudinal section modules 1.1, 1.2, 1.3, a exact alignment of the longitudinal section modules 1.1, 1.2, 1.3 to each other when they are connected to each other via the connecting means 21.

The Figures 2a to 2c show a side wall 3 of a head module similar to the Figures 1a and 1c shown head modules. with structural sections 6.1, 6.2, wherein in the structural section 6.1 recesses 24 for positioning a Figures 2b and 2c The structural post 7 is provided with a slot in the Figures 2a and 2b projections 7.1 shown as hidden lines, with which it engages in the recesses 24. By forming the recesses 24 and the projections 7.1 by means of laser cutting, the structural post 7 is positioned with high dimensional accuracy on the side wall 3 and by a defined positioning of the recesses 24 relative to a reference point 18 also at the reference point 18. A position marking 25 for a Figures 2b and 2c shown weld seam 26 is arranged. As soon as the structural post 7 is positioned on the side wall 3 by means of the recesses 24 and the projections 7.1, the weld seam 26 is carried out along the position marking so that the position marking 25 is destroyed by the weld seam 26. The length of the position marking 25 specifies the length of the weld seam 26 to be welded.

The Figures 3a to 3c show in a highly simplified representation of elements 27.1, 27.2 to be welded further possible information applied/applied to an element 27.1. For example, the edge of element 27.1 is in Fig. 3a with projections 28.1 and recesses 28.2, whereby only the projections 28.1 are in contact with the element 27.2 and the weld seam 26 is consequently only formed along the contact lines on the projections 28.1. Furthermore, for example, on the edge of the element 27.1 in Fig. 3b a bevel 29 is formed along which the weld seam 26 is to be formed and which serves to receive welding material. Furthermore, for example, in Fig. 3c A code 30 in the form of a QR code is lasered onto the element 27.1, which can be scanned by a person carrying out the weld 26 so that more detailed information on the weld to be made is displayed on a screen.
