Description

TECHNICAL AREA

[0001] The present invention relates to a method for assembling a modular track system by providing and connecting at least two longitudinal section modules of the track system, wherein the track system is provided in a modular configuration with at least three separate longitudinal section modules consisting of two end modules and at least one intermediate module, wherein the modules are advantageously arranged relative to one another and then connected to each other. Furthermore, the present invention relates to a track system with a structural design of the support structure adapted to this method, particularly with regard to module-specific support of the support structure on the ground. Finally, the present invention also relates to the use of assembly aids optimized for the modular assembly and process on one or more of the components preferably provided for numerous assembly steps.usable assembly line. In particular, the invention relates to a device and a method according to the preamble of the respective independent claim. BACKGROUND OF THE INVENTION

[0002] When constructing escalators and similar passenger transport systems, a relatively high degree of flexibility and variability is desired, both in terms of design and processes. At the same time, standardization is essential, particularly with regard to manufacturing costs, especially when large production runs are required. This applies especially to the load-bearing support structure of escalators.

[0003] Previously, the time required to manufacture each escalator was comparatively long, particularly in connection with several successive assembly and disassembly processes. These included, for example, test runs, commissioning, precise positioning and alignment, adjustment of components, transportability and on-site installation options for the entire escalator, and other similar constraints. Such intermediate steps were required more frequently in the value chain than desired or conducive to an efficient value creation process. This also resulted in a comparatively large space requirement for handling and (interim) storage of the escalators or the components and semi-finished products intended for them.This too has had a noticeably negative impact on the goal of achieving the leanest possible process and a cost-efficient and variable escalator design, and these disadvantages have not yet been easily overcome.

[0004] For example, when installing escalators or their components, the components to be mounted in the escalator's head sections typically have to be installed at an angle, especially when the escalator's supporting structure has already been erected and extends along its entire intended length, and the angular orientation of the intermediate section between the head modules relative to the head modules is already predefined—that is, when the intended incline / gradient of the escalator has already been structurally implemented. A large portion of the assembly work is usually carried out under these conditions, requiring cranes, support arms, and similar assembly aids designed for heavy loads.

[0005] The disadvantages and high costs described here arise primarily in connection with the construction of the load-bearing support structure of escalators, which is typically built in a truss-like structure, at least in sections, at least on the side levels. Attempts are made to make the joining of individual load-bearing components as efficient as possible through processes that can be at least partially automated, usually using several successive joining devices. The fact that reducing complexity is not trivial is demonstrated by the efforts required, particularly in connection with the most precise possible arrangement and alignment of the components with minimal tolerances.

[0006] Examples include publications EP 3 426 588 B1 and EP 3 426 589 B1, which describe a device and a method for manufacturing a passenger transport system based on several joining steps. EP 3 724 118 B1 can also be cited, which outlines measures intended to facilitate order picking or other preparatory manufacturing steps, as well as the manufacturing process itself, particularly for escalators. Furthermore, the following publications can be mentioned, which describe support structure modules that rest on assembly aids during handling or assembly: JP 2006 213470 A, US 2019 / 134753 A1.

[0007] According to the current state of the art, it is usually necessary to adapt the assembly process to each individual escalator design to a considerable extent. On the one hand, there is an interest in minimizing this type- and application-specific effort. On the other hand, based on the current state of the art, there is also a need for easier standardization of manufacturing steps, including individual assembly steps, and for more general, predefined workflows along the entire process chain, all the way to the fully assembled escalator. Finally, particularly with regard to the flexibility and complexity of the workflows, there is also an interest in a process that is as safe and reliable as possible, and which can be easily implemented largely independently of local conditions or the machinery of a production facility. SUMMARY OF THE INVENTION

[0008] The task is to provide a method and a corresponding device-related or structural design with which escalators, or more generally, travel path devices, can be assembled in the simplest possible way, particularly with regard to final assembly. It is also a task to design a concept for the process flow in the manufacture of travel path devices with the simplest and most standardizable assembly process possible, such that the travel path devices can be manufactured with the highest possible degree of standardization and efficiency, as well as with the highest possible variability and accuracy.

[0009] This problem is solved by a method according to claim 1 and by a device according to the dependent device claim. Advantageous embodiments of the invention are explained in the respective dependent claims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0010] A method is provided for assembling a modular track system by providing and connecting at least two longitudinal section modules of the track system with a coordinated arrangement and alignment of the longitudinal section modules relative to each other, wherein the track system is provided in a modular configuration with at least three separate longitudinal section modules consisting of two head modules and at least one intermediate module, wherein, prior to the connection / marriage of load-bearing support structures of the longitudinal section modules (final assembly of the modularly provided support structures to form the entire support structure of the track system), the support structure of at least one of the head modules, in particular initially the intended lower head module,in an orientation and / or arrangement corresponding to the orientation / arrangement of the supporting structure of the at least one intermediate module (which is preferably horizontally oriented) and is optionally also aligned (particularly in connection with prior or simultaneous individual module-wise assembly measures carried out on individual longitudinal section modules at the time of the respective relative position of the respective module), especially with its end section / platform section in a horizontal orientation. This also promotes a high degree of process variability and enables the realization of a process-oriented mirroring of a modular constructive concept, even in terms of process engineering, up to a phase of final assembly. According to the invention, it is therefore proposed thatThe assembly should initially be carried out module by module, coordinating with the module-specific optimization of the installation / assembly of further components into the respective module, whereby the individual modules can already be arranged in an advantageous orientation at this phase (i.e. before final assembly), namely in such a way that final assembly or the connection of the individual modules to each other can then take place without great handling effort.

[0011] Advantageously, the individual modules are provided or held in a horizontal orientation (i.e., the end section or platform section of the head modules is also horizontally oriented). Not only is the installation of components in the modules advantageous in such a horizontal orientation of the corresponding longitudinal section, but so is the application of sheet metal connections intended to join adjacent support structures, particularly for preferably force-fit sheet metal connections applied using screws or locking bolt connections (or rivets), for example, exclusively manually with a manually applied assembly tool.

[0012] Particularly in connection with the finding that track devices can be manufactured or assembled in a particularly advantageous modular or module-by-module manner (at least as far as the installation of further components into the supporting structure is concerned), the present invention provides an advantageous process and an advantageous device-technical setup for downstream steps relating to the assembly of all longitudinal section modules of the respective track device, in particular such that the respective longitudinal section module can be arranged in a predefined / predefinable manner with respect to the relative position to at least one further longitudinal section module (in particular with reference to several module-specific reference points) and can also be connected or joined in the further course of the assembly process.This can be supported, ensuring a comparatively high degree of accuracy in positioning relative to each other.

[0013] This facilitates the handling and mounting of the individual modules on the one hand, and on the other hand, it also simplifies the process of connecting / marrying pairs of modules, especially when arranged in a straight line on an assembly line from the point at which the module-specific equipment is completed with built-in components such as a drive unit on the upper head module, particularly when the respective end section of the head modules is (initially) horizontally aligned and also when the intermediate module is horizontally aligned.

[0014] The concept according to the invention can therefore also be described as follows: Instead of assembling complete travel systems (e.g., escalators), the separate assembly of longitudinal section modules offers significant advantages, particularly with regard to ergonomics, occupational safety, assembly efficiency, and space utilization. The process described here can minimize the effort required for handling and positioning the modules, especially during the phase in which they are joined to form a complete unit (with the supporting structure extending over the entire length of the travel system). The positive aspects of modular assembly are not diminished in this process. Preferably, the modules are already fed to a final assembly line in the correct orientation and sequence (especially in the sense of "just-in-sequence" provision).(correctly sequentially); after separate / module-specific assembly of the modules, these are connected to each other in a longitudinal section module connection arrangement. This significantly minimizes handling effort, especially with regard to positioning effort before connection (for example, the modules can be held in the same clamp or aligned very precisely with unchanged storage / support, e.g., by supporting them at module-specific integral reference points on the side walls of the respective support structure).

[0015] For the purposes of this disclosure, the general term "travel device" refers primarily to escalator devices (in particular including moving walkways) and moving walkways (the latter especially in stepless configurations with at least an approximately level orientation or negligible gradient), as well as related passenger transport devices with an endlessly circulating transport mechanism. A travel device comprises, for example, segments or units forming the transport mechanism, in particular steps or pallets, which are connected to driven chains or comparable traction elements and guided in guide rails. The guide rails, as well as a chain (or a similarly acting traction element) and other components of the travel device, are, for example, located within load-bearing structures extending substantially laterally in the axial direction.Supporting structures are typically formed from two opposing side wall units connected by crossbeams and optionally a base unit, and may also include truss-like struts. The term "track system" also refers specifically to modular track systems, which are modularly constructed from several longitudinal sections or modules, each with its own individually designed or longitudinally specific supporting structure, and can be assembled / mounted module by module.

[0016] Therefore, the travel path devices described here can also include moving walkway devices, i.e., travel path devices oriented at least approximately horizontally without steps but with individual travel path elements which are not intended to overcome a gradient, but rather form a largely level track; in this respect, a reference to a kink or a sloping section is to be understood here as meaning that the corresponding section is described largely independently of any / the actually realized incline.

[0017] For the purposes of this disclosure, the general term "assembly" or the more specific term "final assembly" generally refers to the assembly of the entire / complete supporting structure of the track system, which may also include all longitudinal section modules intended for use (two end modules and at least one intermediate module); this final assembly is also described here as a pairwise modular connection / marriage of the supporting structures of at least two longitudinal section modules, or encompasses at least this connection step. Alternatively, the term "assembly" may also include preparatory steps such as picking / providing / keeping components available for a respective longitudinal section.Modules or the entire travel path device; according to the present disclosure, the invention primarily relates to steps and aspects that are downstream of order picking, i.e., do not include order picking in the narrower sense.

[0018] In contrast, the term "modular assembly" (or synonymously "modular / modular / module-specific assembly") refers specifically to the assembly of only certain individual modules or their components within the corresponding module, for example, specifically in the case of a head module, where, for example, components of a drive are installed in the upper head module, or guides, rails, cladding parts or balustrade components are (pre-)assembled in only one of the modules.Depending on the design of the manufacturing process, the assembly of components can take place, at least partially, in a phase where the modules are still handled separately from each other, or in a phase where the modules are already joined together; this possibility of variation applies, for example, to the individual steps / pallets; therefore, the use of the term "assembly" should not be understood as restrictive with regard to specific phases of the creation process of the complete track system or its supporting structure.

[0019] According to the present disclosure, "marrying" is to be understood as the process of finally attaching the individual modules to one another, within the context of creating the entire supporting structure of the complete track system.

[0020] For the purposes of this disclosure, the term "longitudinal section module" is to be understood generally as a load-bearing longitudinal module of the track system, i.e., a module that forms a longitudinal or length section of the track system and provides the supporting structure for it (i.e., a structurally complete component of the track system in the corresponding length range). This term therefore encompasses the terms "head module" and "intermediate module." The term "head module" refers to a module located at one end of the track system and optionally refers to both types of head modules (upper and lower head module, also referred to as upper and lower sections); thus, this term can equally refer to the module at the upper or lower end of the track system.In escalator systems, the end modules typically extend across the entire angle of inclination of the system, thus spanning the kink or transition from the inclined longitudinal section to the respective horizontal longitudinal section. In this context, the term "platform section" refers to the portion of the respective end module that, in its intended configuration, is aligned at least approximately in a horizontal plane. Therefore, when describing the arrangement / alignment of the respective end module, reference is also made to the orientation of this platform section (or its main plane of extension), particularly when the absolute length of the platform section is greater than the absolute length of the inclined section.The term "connecting inclined section" (also referred to as a "stub" in technical literature) refers specifically to the inclined section intended for connecting / marrying another longitudinal section module. This inclined section can be of varying length depending on the function of the respective head module. This implies that the individual modules are intended to be connected to each other within the area of ​​the intended inclined longitudinal section. If several intermediate modules are provided, depending on the process priority, either the intermediate modules are connected / married to each other first, or each head module and intermediate module are connected first. The general term "longitudinal section" can refer either to a longitudinal section module or to a specific longitudinal section, particularly of the head module (i.e., the platform section or the inclined section).

[0021] The term "longitudinal section", which is even more general than the term "longitudinal section module", refers, unless further specified, equally to the head sections and the at least one intermediate section and is used according to the present disclosure when modularity or a modular design or a strictly modular process is not necessarily required or can also be varied or modified according to the invention, or when reference is made to a process or a device-related state which is still prior to the intended modular construction of the individual modules, e.g. concerning the joining of individual longitudinal sections of a head module to form the entire head module.In other words: If, according to the present disclosure, individual longitudinal sections are mentioned without explicitly designating them as longitudinal section modules, then not only the individual modules but also longitudinal sections of a single module may be affected, in particular a platform section (e.g. first longitudinal section) and an inclined section (e.g. second longitudinal section) of a head module, for which a specific connection process may be provided (especially in the area of ​​the bend); for example, individual longitudinal sections of a module may be positioned relative to each other by means of form-fitting contours, e.g. in connection with a material-bonded connection of these longitudinal sections to create the entire supporting structure of the respective module.

[0022] The supporting structure of a travel path device or of a respective module can essentially be formed by opposing side wall units and connecting crossbeams (also referred to as cross members), wherein a side wall unit is formed by at least one side wall and, in particular, by a top chord and / or a bottom chord; the modular manufacturing process described here can also include the connection of a base unit with the side wall units; however, it has been shown that such a base unit does not necessarily have to fulfill a load-bearing function, but is designed, for example, to collect and, if necessary, drain oil from a drive, or to provide a cover and / or access from below to the supporting structure.is designed to be optimized for the roadway device; in this respect, the ground unit is to be understood as an optional component which can also be functionally separate from the supporting structure, but which can optionally also assume an additional supporting load-bearing function if desired in individual cases.

[0023] The term "side wall" refers to a side structure that, for example, extends at least partially across a single plane, but is alternatively or additionally reinforced at least partially by profiles, struts, or beams extending beyond one or more of the planes. Generally, the side wall is formed from structural elements or sections that, as planar structural sections, absorb forces in multiple directions and / or are rod-shaped or...Strut-like structural parts / sections / elements absorb the respective forces only along the longitudinal extent determined by the orientation (tension or compression); such components of the load-bearing structure can also be referred to by the English terms "truss member" or "truss section," whereby, according to the present disclosure, a truss-like structure is not necessarily required; the term "truss" can nevertheless be considered appropriate here, since the side wall usually has a truss-like structure, at least in sections, i.e., the force transmission is intended to occur in structurally predefined directions. The side wall is thus designed, for example, as a closed surface, as a pure truss, or as a structure with portions (or sections) of closed surfaces and portions with a truss structure.Optionally, at least some of the load-bearing structural parts / sections of the side wall are formed from flat material, in particular sheet metal, e.g., structurally planar sections or stiffening (in particular) curved L- or U-profile sections in the area of ​​welded connections to other structural parts / elements / sections. According to the understanding of this disclosure, a "side wall unit" comprises the side wall described herein as well as the flanges associated with this side wall, in particular a top flange and a bottom flange, wherein the flanges may be integral with the side wall, integrated, or formed separately from one another. These flanges 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 track system.Therefore, the term side wall unit can refer to the entire side structure encompassing the upper and lower chords, and the term side wall can refer to the side structure arranged between the upper and lower chords.

[0024] The terms top chord and bottom chord, which together are also referred to as chords, denote structural components / elements or corresponding load-bearing sections extending longitudinally in the area of ​​an upper or lower edge of the side wall, respectively, for absorbing loads in the longitudinal direction of the track system, in particular bending loads, which primarily lead to tensile stresses in the bottom chord and compressive stresses in the top chord. The chords are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles, or hollow profiles, and thus exhibit a favorable area moment of inertia for absorbing the bending loads. The chords stiffen the supporting structure and form external corner points, with the chords and / or the side walls optionally serving for attaching further components of the track system.The chords can still be designed as components separate from the side wall; however, preferably at least a portion of the chords is formed integrally with the side wall, for example by bending the side wall. Particularly preferably, the top chord is designed as a hollow profile with four walls, wherein two walls are formed by the L-shaped bent side wall, which in this area is made of flat material, and two further walls are formed by a flat material component, also L-shaped and separate from the side wall. Similarly, the bottom chord is preferably designed as a hollow profile with four walls, wherein two walls are formed by the L-shaped bent side wall, which in this area is made of flat material, and two walls are formed by the bottom unit, which is also L-shaped and made of flat material. The components forming the walls are preferably welded together.The upper chord and / or the lower chord can also be provided entirely as a single piece with the side wall or entirely separately from the side wall (especially also in the sense of a procedural variation).

[0025] A "structurally resilient" point or component of the supporting structure is understood to be one that is temporarily capable of absorbing at least the forces resulting from the self-weight of the track system or the corresponding module, for example, in connection with individual assembly steps. This term is used, for example, with regard to the reference points described here.

[0026] In this context, "load-bearing" refers to a component or part (section) of the supporting structure which is designed to withstand the prevailing static and dynamic forces and moments during the intended use of the track system, even under continuous load for several years.

[0027] For the purposes of this disclosure, the term "fastener" refers specifically to a screw connection or a rivet connection, particularly a so-called locking ring bolt connection, especially in connection with the joining of modules. The person skilled in the art may specify whether such a preferred rivet connection or locking ring bolt connection should be replaced by, for example, a screw connection in individual cases or at individual connection points. Preferably, the rivet connection or locking ring bolt connection includes at least one visual inspection mark, particularly one that removes material. The fasteners are preferably applied in conjunction with force-fit metal sheet connections to the supporting structures of adjacent modules.

[0028] It is worth noting that the present invention is based in particular on the concept that at least a substantial portion of a side wall, a top flange, a bottom flange, and / or the entire side wall unit, which defines the overall shape, is made of flat material, in particular sheet metal, wherein at least one reference point is preferably defined on the flat material. Using processing methods available today for flat materials, in particular laser cutting, reference can be made to at least one reference point during the subsequent assembly of the track system, so that assembly can be carried out with very small tolerances and the track system can be manufactured with advantageously high dimensional accuracy.In this way, the comparatively precise relative or absolute positioning of individual components of the travel path device with respect to at least one reference point can be enabled, and further measures for aligning and positioning the components, especially relative to each other, can be largely dispensed with. The invention particularly preferably comprises the teaching of introducing further references, in particular corresponding recesses (in the sense of additional component-specific mounting reference points), on the flat material in addition to the at least one reference point, which is arranged particularly in the corresponding side wall, using the same machining method. These further references allow additional components to be arranged directly on the recesses and thus in a defined position relative to the at least one (master) reference point with high accuracy.Reference recesses are also incorporated, in particular, in areas of the flat material that can be subjected to further processing steps, especially bending processes, following laser cutting. This allows the referencing concept described here to be implemented for multidimensional positioning in space with respect to at least two or all three spatial directions. Furthermore, the invention includes the teaching that the reference point is defined by, for example, a circular recess or by its center point, at which further positioning devices (i.e., assembly aids such as side support units) can be clamped for positioning individual longitudinal sections or components. In particular, the respective component with the reference point, or the entire module, or even the entire travel device, is lifted at the at least one reference point or supported around a reference axis formed by several reference points.B. also suspended or lifted from it or tilted around this axis. At least a significant portion of a top chord or a bottom chord can also be formed from a profile, whereby appropriate machining processes, in particular tube laser cutting processes, for forming a reference point and / or further references are also available for profiles.

[0029] The general term "components" refers to components to be installed in the respective track systems or modules of the track systems, e.g., relating to electrical systems, drives, guides, or the like. If a structural component is required to perform a load-bearing function, particularly for the intended continuous load, it is referred to as "load-bearing components" or structural parts / elements / sections in connection with the supporting structure.

[0030] For the purposes of this disclosure, the term "coordinated arrangement and alignment" means that the individual modules are already pre-assembled in such a way that no additional assembly aids are required for lifting, positioning, and / or aligning the modules in order to join them together as intended. Preferably, purely form-fit metal sheet connections are applied for joining / marrying by means of force-fit / form-fit fasteners, in particular in at least two fastening levels per metal sheet connection.

[0031] Personalized terms, unless explicitly formulated in the neuter form, may refer to all genders within the context of this disclosure. Any English terms or abbreviations used herein are standard industry terms and are familiar to those skilled in the art in English.

[0032] According to one embodiment, before connecting / joining the support structures of the at least three longitudinal section modules, the two end modules with their support structures are arranged and aligned in an orientation and / or configuration for final assembly (particularly for module-specific assembly with advantageous accessibility) that corresponds to the orientation of the at least one intermediate module provided between the end modules, in particular by aligning a platform section of the respective end module at least approximately horizontally and tilting a connecting inclined section of the respective end module (thereby) obliquely upwards or downwards. This also minimizes the handling effort with regard to comparatively voluminous and massive support structure sections. Connecting / joining can, for example,This can also be achieved in a purely form-fit / force-fit manner, which makes the assembly process even more flexible and variable, and which also allows a sequential manufacturing method to be implemented in a comparatively simple way with minimized storage and space requirements.

[0033] According to the invention, each longitudinal section module is arranged and supported by means of at least one support and movement device in a module-specific manner and is supported at reference points integrally provided on the supporting structure of the longitudinal section module. This also enables comparatively precise alignment with minimized handling effort. The reference points can form a reference axis about which the travel path device can be tilted.

[0034] The track device is supported in structurally load-bearing reference recesses integrally incorporated into the side wall units of the supporting structure of the respective longitudinal section module, on at least one support and movement device.

[0035] It is worth noting that the support and movement devices described here, by means of which the individual modules can be arranged, positioned, and aligned, can also be provided by so-called trolleys or carts, which are available in many machine halls or production facilities, especially if the trolleys or carts have integrated height and / or lateral adjustment. Accordingly, it has been shown that the positioning accuracy described here can be achieved not only by means of the reference hole grids described here in predefined / standardized positioning devices (compare the disclosure regarding positioning units equipped with standardized guides or plug connections on alignment plates), but also by means of comparatively simple trolleys or carts, which, for example,These components can be used in conjunction with a crossbeam placed on top of them. For example, the respective crossbeam is provided by two L-brackets welded together from 8mm steel sheet (especially for the respective upper head module), whereby laser-cut reference recesses or corresponding coupling holes may be provided / incorporated in the L-brackets. The respective lower head module and the respective intermediate module are, for example, mounted on U-profiles made of 8mm laser-cut sheet metal, which form the crossbeam. Flat bars may be welded to one of the L-brackets or to the respective U-profile.The crossbeams described here as double L-brackets or U-profiles, preferably made of 8 mm steel sheet (laser-cut), can each be arranged and secured on the respective support and movement device by means of brackets and supports (in this respect, the positioning units described here can be characterized by these features). For example, each bracket is screwed onto a support to prevent it from slipping out. A side support unit can also be provided by a preferably laser-cut and welded L-bracket made of 8 mm sheet, which can be screwed to the respective crossbeam. The through-bolts described here, in conjunction with relative positioning by utilizing the reference recesses in the respective side wall, can also be applied to side support units designed in this way.

[0036] An absolute (lateral) position reference, particularly in the transverse direction, can be provided, for example, by a tree (beam, vertical support) or point in a machine hall (e.g., also a door frame), from which a geometric definition of at least individual sections of the assembly line can be specified, e.g., using at least one dimensionally stable profile (e.g., L-profile) which is fixed to the floor in a strictly axial orientation (or a differently defined fixed bearing side; compare the disclosure regarding the optionally usable side stop), possibly also using optical assembly aids such as a laser beam or a planar laser beam plane.

[0037] According to one embodiment, at least one of the head modules is tilted from a horizontal orientation of the pedestal section of the head module, selected for the upstream assembly, to an inclined orientation of the pedestal section, so that a connecting inclined section of the head module is horizontally aligned and aligned with the longitudinal orientation of the intermediate module (arranged in a straight line). The tilting movement is preferably carried out by means of a tilting device / tilting kinematics, and is preferably performed after the module-specific assembly from module to module and immediately before the modules are connected. This also allows for an advantageous arrangement / orientation of the respective end / pedestal section over a long phase of the manufacturing process. The tilting device / tilting kinematics can, for example, be...It can also be integrated into the respective support and movement device on which the module can be arranged. The tilting movement can be achieved by support on the module's own reference axes, i.e., by tilting around reference points / axes or reference recesses arranged in the side wall units of the supporting structure.

[0038] According to one embodiment, after the modular assembly of each longitudinal section module (particularly in the aforementioned coordinated arrangement and orientation), the supporting structures of adjacent longitudinal section modules are connected / married together in pairs (final assembly). The sequence of this paired connection is variable; it has been found to be particularly advantageous to first connect the lower end module to the corresponding intermediate module. The modules can already be arranged in the line relative to each other in the configuration in which the connection is to be made, for example, by simply positioning the modules axially relative to each other and, if necessary, tilting them about a (reference) axis.

[0039] According to one embodiment, each longitudinal section module is arranged and supported by means of a support and movement device and is / remains optionally movable relative to the ground by means of the support and movement device, wherein the support and movement device is configured for the horizontal alignment of a platform section and / or an inclined section of the head module, and wherein a support and movement device is preferably configured for tilting / tipping the head module by a minimum tilting angle (in particular with the minimum tilting angle corresponding to a structurally predetermined inclination angle of the travel device), so that a platform section and an inclined section (if required or at the given process time) change their inclination / orientation in a mirror image (in particular from a horizontal orientation to an inclined orientation and vice versa).This design also facilitates a variation in orientation, particularly with regard to good accessibility of the platform section or the sloping section.

[0040] According to one embodiment, the respective head module is arranged and supported by means of a support and movement device, which is designed such that a platform section of the head module can be tilted from a horizontal orientation to an inclined orientation, so that a connecting inclined section of the head module is / becomes horizontally aligned and is / becomes aligned with the longitudinal direction of the intermediate module (falling in a line). This allows the transition from a module-specific manufacturing phase to a manufacturing phase affecting the entire track system to be achieved with a comparatively small displacement or a relatively easy-to-use tilting device, for example, without having to change the arrangement or relative position of the respective module in the longitudinal or transverse direction.

[0041] According to one embodiment, at least one of the head modules, with its platform section, is tilted towards the ground and aligned such that the platform section of the head module is arranged in an inclined orientation with the predefined angle of inclination (α) at ​​least below the alignment / support plane of the (horizontally oriented) intermediate module, optionally below the subsurface / ground, e.g., in a pit. This also makes it possible to keep the intermediate module in at least an approximately horizontal orientation.

[0042] An arrangement / extension of the platform section of the upper head module in a pit or the like is not necessarily required, but can be advantageous, for example, if the intermediate module is to be aligned as strictly horizontally as possible and also be arranged relatively close to the ground, i.e., flat just above the ground.

[0043] According to one embodiment, the head modules and the at least one intermediate module of the track system to be assembled are stored, supported, and aligned one after the other in the intended sequence, module by module, whereby the longitudinal alignment of the modules can also be pre-aligned. This facilitates an assembly process that requires little space and only relatively slim assembly aids.

[0044] According to one embodiment, the longitudinal section modules of several guideway devices are stored, supported, and aligned one after the other in the intended sequence along the same assembly line, for example, a first guideway device comprising three longitudinal section modules and a second guideway device comprising four longitudinal section modules. This also facilitates the efficient production of larger quantities without sacrificing the high degree of variability, flexibility, and customizability described here.

[0045] The term "assembly line" can also be understood as meaning that the individual modules are arranged along a line / axis, which can optionally be predefined by rails, a side stop, or similar guide aids. The person skilled in the art can specify which guide aids are particularly suitable in each individual case; in this respect as well, the concept according to the invention offers comparatively large degrees of freedom and is not limited to a specific configuration of an assembly line.

[0046] According to one embodiment, at least one intermediate module of the travel path device to be created is lifted and tilted into such an orientation that the upper head module can be connected to the intermediate module in an arrangement with its platform section in at least an approximately horizontal orientation.

[0047] According to one embodiment, the upper head module with its inclined section is arranged in an at least approximately horizontal orientation such that it can be connected to an intermediate module that is also oriented at least approximately horizontally. This also facilitates a process in which the intermediate module can remain in a horizontal orientation.

[0048] According to one embodiment, the individual longitudinal section modules are transferred to a longitudinal section module connection arrangement, particularly on the same assembly line, wherein the longitudinal section modules can be connected to each other in pairs in the longitudinal section module connection arrangement, particularly purely by force / form fit without material connection, and particularly in an arrangement supported relative to each other in reference axes and reference recesses via the side walls of the support structures. The transfer can be effected, for example, by a pure translational movement, in which the individual modules are moved closer to each other and are, for example, only spaced apart from each other in the longitudinal direction to such an extent that a tilting movement at the respective end module positions the sections of the support structures to be connected relative to each other.Therefore, the assembly line can initially serve only to align the individual modules, and in a downstream longitudinal module connection arrangement, tilting and / or lifting or lowering of the respective module or the entire support structure of the track system can also take place. In this respect, the longitudinal module connection arrangement optionally includes a lifting / tilting kinematic mechanism, at least module-specific for the respective support structure and optionally also for the entire track system, particularly ground-based without additional cranes or similar means that lift the modules from above. Using the longitudinal module connection arrangement, the support structures of the individual longitudinal modules can be positioned relative to each other in such a way that the sheet metal connections described here can be applied to form the respective load-bearing module connection, optionally also manually.

[0049] The aforementioned problem is also solved by a track device according to the corresponding dependent device claim, namely by a track device with at least three interconnected longitudinal section modules consisting of two head modules and at least one intermediate module, manufactured by a method described above, in particular by positive / force-locking pairwise connection of the individual longitudinal section modules in a relative position achieved by aligning and arranging the at least three longitudinal section modules forming the track device on an assembly line (in particular on the same assembly line); wherein the track device can be supported in a load-bearing manner at reference points integrally provided on the supporting structure of one or the respective longitudinal section module on at least one support and movement device and preferably also on side support units supported thereon;This is particularly true when using the assembly aids described here in combination with the reference points / recesses (preferably circular recesses) integrally provided on the supporting structure of each longitudinal section module. This results in the aforementioned advantages, especially with regard to mirroring and coordinating design features and process-related (manufacturing) characteristics and requirements. Advantageously, the side support units provide standardized coupling devices.

[0050] According to one embodiment, the track system can be tilted about at least one reference axis formed by the reference points integrally provided on the supporting structure of each longitudinal section module. This offers advantages both during the module-specific assembly phase and during the assembly phase of the entire track system (joining the supporting structures).

[0051] According to one embodiment, each longitudinal section module has at least one reference axis formed by reference points integrally provided on the supporting structure of the longitudinal section module and load-bearing by the self-weight of the track system. The longitudinal section module can be supported on this axis by at least one support and movement device, in particular with the number of reference axes corresponding to the number of support and movement devices or similar support points used, and especially at least two reference axes per module. This offers advantages both with regard to the optimal alignment of the individual modules and with regard to the relative distance in the longitudinal direction.

[0052] According to the invention, the travel path device is supported in structurally load-bearing reference recesses integrally incorporated into the side wall units of the supporting structure of the respective longitudinal section module, and preferably also tiltable about at least one reference axis formed by the reference recesses. This facilitates (final) assembly in a comparatively streamlined assembly line using relatively slim assembly aids, thereby further reducing the equipment and space requirements for manufacturing. Good accuracy of the reference recesses, and thus also of the arrangement and alignment of the reference axis, can be achieved in particular by laser cutting, especially during the production of the flat material geometry of the respective side wall (unit).

[0053] The reference recesses described here can also be used for arranging adapter plates, particularly in a preparatory phase when positioning two modules end-to-end, before the modules are positively / force-fittedly connected / joined. The adapter plates can be mounted on the reference recesses of a first module and facilitate the aligned docking of the adjacent (second) module, especially by providing corresponding tapered guides (at least one) on each adapter plate; the adapter plates are advantageously mounted on the outside of the respective side wall, particularly at least approximately centrally with respect to the overall height of the cross-section of the supporting structure.A corresponding guide pin can be mounted on the adjacent (second) module, in particular also at at least one reference recess, and especially also in the relative position to the supporting structure described here. Such adapter plates can be provided in a simple and cost-effective manner, especially from sheet metal.

[0054] It is worth mentioning that the adapter plates can facilitate the joining of the modules both when working with a pit (one of the head modules is tilted with its end section below the working level and extends deeper than a machine hall floor into a pit, where it can optionally be supported) and when working without a pit; when working without a pit, the working level for the entire supporting structure (i.e., for all modules to be joined) can be raised, and / or the module can be tilted in such a way that the head module being tilted downwards is positioned with its free end still above the floor of the machine hall; in this phase, at least the head module may be suspended from a crane, so that the adapter plates can facilitate the alignment or at least the guiding of the module as it approaches the adjacent module until it is flush (or until it meets a gap specified / predeterminable by the adapter plate).

[0055] For example, the respective adapter plate is used as follows, here using the example of final assembly of the supporting structure without using a pit: Attaching the adapter plate to the corresponding reference recesses of a / the first module, in particular to at least two reference recesses; at least one bolt is loosened on a / the external support and movement device (e.g., rear carriage) of a / the lower head module (lower part), whereupon the lower head module can be lifted (or pushed upwards) on the platform section and tilted about the reference axis on the inclined section until the inclined section is horizontally aligned (pivot point realized in particular via a pair of bolts); after aligning via the reference recesses, the lower head module (lower part) can be positively / force-fit connected to the adjacent intermediate module (middle part), in particular by riveting; thereupon, the middle part (intermediate module) connected to the lower part (lower head module) can be lifted (or pushed upwards) by a tilting movement about reference recesses of the lower part.(pushed upwards) so that a sufficiently large clearance to the machine hall floor is created to join the upper head module (also in a tilted orientation) with the intermediate module - the pivot point is preferably defined exclusively by a pair of bolts arranged in the corresponding reference recesses on the lower head module; preferably simultaneously, the upper part (upper head module) is lifted (or pushed upwards) by a tilting movement, whereby the upper part rotates about a reference axis arranged in the area of ​​the free end of the platform section, and then the upper part is placed in the adapter plates mounted on the intermediate module, whereby, for axial approximation of the modules, e.g.A clamp or similar tool can also be used to clamp between the modules; after aligning using the reference recesses, the upper head module (top part) can now be positively / force-fit connected to the adjacent intermediate module (middle part), in particular by riveting; .

[0056] The steps outlined here demonstrate that the form-fit / force-fit connection concept for joining the modules can be implemented in a highly flexible and variable manner with high precision and minimal assembly aids, largely independent of location (i.e., both as a preparatory measure at the manufacturer's site and on a construction site for final assembly at the destination). The respective adapter plate can be easily provided regardless of location and can be designed so cost-effectively that even single-use (if not reusable) costs can be factored in without difficulty.

[0057] The aforementioned task is also solved by using assembly aids for forming an assembly line for aligning, arranging, and feeding a support structure of a track device (in particular a track device described above) consisting of at least three longitudinal section modules to be connected to each other to a longitudinal section module connection arrangement, which is intended for connecting the individual longitudinal section modules in pairs (in particular positive / force-fit connection), namely by using module-specific support and movement devices and positioning units for storing and aligning the respective longitudinal section module for carrying out a procedure described above on the same assembly line.wherein each longitudinal section module is arranged and supported in a module-specific manner by means of at least one of the support and movement devices and is supported in reference points integrally provided on the supporting structure of the longitudinal section module, wherein the track device is supported in structurally load-bearing reference recesses integrally incorporated into side wall units of the supporting structure of one or more of the respective longitudinal section modules on at least one support and movement device. This allows the aforementioned advantages to be realized, in particular when referring to reference points integrally provided on the respective module.

[0058] Summary: When it comes to track systems, it is important to ensure a good compromise between standardizability and variability, especially with regard to the supporting structure.According to the invention, a modular concept is provided with regard to both the structural design and the assembly method for the entire supporting structure of the track device, wherein by providing and connecting at least two longitudinal section modules of the track device, which is provided in a modular configuration with at least three separate longitudinal section modules consisting of two head modules and at least one intermediate module, a connection / marriage of load-bearing supporting structures of the longitudinal section modules of at least one of the head modules, in particular initially the intended lower head module, takes place in an orientation and / or arrangement corresponding to the orientation / arrangement of the supporting structure of the at least one intermediate module, in particular with the platform section of the (respective) head module in a horizontal orientation.This also ensures good accessibility and ergonomics right up to the final assembly phase. The invention further relates to a corresponding guideway device. BRIEF DESCRIPTION OF THE FIGURES

[0060] The invention will first be explained with general reference to all reference numerals and figures. Specific features or individual aspects, or aspects of the present invention that are clearly visible / representable in the respective figure, will be addressed individually in connection with that figure.

[0061] A travel path device 10 (in particular, a moving walkway / escalator device) is provided, comprising at least three longitudinal section modules 11, namely an upper end module 11a and a lower end module 11b, as well as at least one intermediate module (in particular, a straight module without a kink) 11c, to which the end modules are connected. Each end module 11a, 11b has a platform section 11.1 (or landing section, first longitudinal section, or end section) with a horizontal orientation as intended. In a transition area 11.2 (kink), the platform section transitions into an inclined section 11.3 (or second longitudinal section of the respective end module) with an inclined orientation as intended. At the kink, the supporting structure forms an angle of inclination α corresponding to the inclination between the platform section and the inclined section. A free end 11.1a of the platform section marks the beginning or end of the transition area.the end of the guideway device at its respective end face 11.4. Depending on the design of the guideway device 10, several interconnected intermediate modules can also be provided, so that the respective (first) intermediate module is / will be connected to at least one further intermediate module 11c' (advantageous length scaling based on a comparatively short basic module length unit of a standard intermediate module).

[0062] Advantageously, the supporting structure 15 of the respective longitudinal section module 11 is conceptually comparable: Opposing side wall units 17, in particular comprising at least one profile section bent from flat material, are each formed from a side wall 17a, 17b and an upper band (upper chord section) 17.7 and a lower band (lower chord section) 17.9 and are connected to each other by means of crossbeams 16.1 (e.g., crossbeams, especially with hollow profiles). The side walls 17a, 17b are preferably formed largely or optionally entirely from flat material, which may be bent at least in edge areas and welded to further flat material sections. In this respect, any structural element-like design can also be provided from flat material sections, in particular without the need to install semi-finished profile products.This enables, among other things, a kind of standardization of material thicknesses that may be individually preferred in specific cases, also in the area of ​​structural stiffening, which also allows the applied joining technology (be it material joining or force / form joining) to be applied even more precisely, with a view to even higher dimensional accuracy (minimized tolerances).

[0063] Therefore, the supporting structure 15 can also exhibit, at least in sections, a truss-like configuration of individual strut-like structural sections primarily intended for tensile or compressive loads. Such a truss-like design or orientation of the individual sections can also be customized, particularly depending on the selected structural components, especially during a flat material processing phase. Advantageously, a truss-like configuration also comprises, at least partially or even essentially, only flat material sections (instead of profiles predetermined by semi-finished product manufacturing). This design, created at least largely from flat material, has proven particularly advantageous with regard to the modular manufacturing concept described here and the scalability favored in this context, not least with respect to the achievable accuracy.

[0064] Furthermore, the respective longitudinal section module 11 can also include a base unit 14, which, however, does not necessarily have to have a load-bearing function. Optionally, the base unit extends only two-dimensionally and primarily serves as a fascia (whereby the base unit can, for example, also have recesses that facilitate access to the supporting structure), or optionally, the base unit can also include bent profile sections (in particular, L-shaped bent end regions) and be structurally stiffened and connected to the actual supporting structure 15. A person skilled in the art can specify an integration of the base unit into the supporting structure that is suitable for the respective application; the design method according to the invention also offers possibilities for variation in this respect.

[0065] Each completed module 11 may also include a balustrade 12 and a handrail 13 or the corresponding longitudinal section thereof.

[0066] Advantageously, at least one reference point 17.1 is formed in each side wall unit 17, which can be defined by a geometrically predefined (in particular laser-cut) reference recess 17.3 (in particular a material recess created by material processing). A significant portion of the referencing during the relative and / or positioning of the individual components can advantageously be carried out via these reference recesses 17.3, which can, for example, be repeated after a predefined length unit of, say, two or three meters and can therefore be redundantly provided. This also applies, optionally, to all handling and assembly steps downstream of the creation of the reference recesses 17.3, up to the final construction of at least the supporting structure and, optionally, also the entire track system.In this context, further mounting / fastening points for at least one further component to be attached to the supporting structure may also be provided or positioned relative to the corresponding reference point 17.1 (for example, also predefined by laser cutting or a comparably precisely adjustable machining process), in particular with reference to reference points which are arranged in a height or length section of the corresponding flat material section for which a comparatively high (manufacturing) accuracy can be ensured, especially in the context of laser cutting processes.

[0067] The reference points 17.1 can considerably facilitate the storage and handling (especially tilting) of the respective module 11, particularly in connection with paired connection / marriage of the modules, and increase the accuracy achievable to date using comparatively simple and compact assembly aids (especially in coordination with other assembly aids enabling comparably precise storage on the ground 1, such as side support units, by means of which predefined positioned coupling points are provided, via which the modules can be coupled at the reference recesses). Preferably, the individual modules 11 are connected to one another in a plurality of fastening axes 34 by means of positive-locking and / or force-locking (load-bearing) module connections 30 or sheet metal connections 31, while the modules 11 are supported in the reference recesses.This comparatively precise yet easy-to-use connection technology (e.g., also purely manual) is described in more detail elsewhere.

[0068] The following reference numerals denote reference planes or similar geometric features that facilitate the understanding of the present invention: Floor 1 (in particular floor, subfloor, machine hall floor level or the like); floor level E1 (e.g., level of a machine / assembly hall); alignment / support height level Exy of the intermediate module, in particular horizontal; structurally load-bearing reference axis Y17, in particular for tilting movement, provided by means of the side wall units; horizontal longitudinal direction x, transverse direction y, vertical direction z;

[0069] The Figuren 5A bis 5C show several longitudinal section modules 11 of a modularly constructed and modularly assembleable track device 10, namely Figur 5C a longitudinal section module 11b designed as a lower head module, Figur 5B a longitudinal section module 11c designed as an intermediate module, and Figur 5A A longitudinal section module 11a designed as an upper head module. The longitudinal section modules 11 each have a supporting structure 15 with two side wall units 17 and crossbeams 16.1. Each side wall unit 17 structurally comprises at least one side wall 17a, 17b, an upper chord 17.7 and a lower chord 17.9.

[0070] The supporting structure 15 of each module consists largely of side walls or side wall units constructed from flat material. The side wall 17a, 17b is formed essentially from flat material at least in one outer plane and / or at least over a central height section 15.1 (the central height section can constitute at least 75% or even at least 85% of the total height of the corresponding side wall / unit). Structural sections formed by recesses in the flat material act as structural posts and / or as simple diagonal or cross-shaped cross braces are formed in the flat material in the corresponding side wall plane or slightly offset from it. The offset arrangement in several planes can be achieved, for example, by bending the flat material in one piece, either at a single angle or at multiple angles.The structural sections, designed as structural posts, divide the side wall 17a, 17b or the corresponding side wall unit 17 into panels. Furthermore, load-bearing elements and cross braces 16.1 are arranged or attached to the structural sections provided by the flat material, in particular by welding or other means, e.g., by a material bond.

[0071] The respective side wall 17a, 17b is preferably formed integrally, at least in sections, with the corresponding upper chord 17.7 and the lower chord 17.9; in particular, the flat material forming the respective side wall 17a, 17b forms a first wall (or a corresponding section of flat material) and a second wall of the upper chord 17.7 bent in an L-shape from the first wall; a third wall and a fourth wall of the upper chord 17.7 are formed by a further structural element or section formed from an L-shaped bent flat material and welded to the flat material forming the corresponding side wall 17a, 17b. The lower chord 17.9 is formed in the same or a comparable manner.9. A first wall is formed by bending the flat material forming the side wall in an L-shape from the side wall, and a second wall is formed in an L-shape from the first wall; a third wall and a fourth wall of the bottom chord 17.9 are formed by a bottom unit 14 that is bent in an L-shape at least in sections. The structural design of the top and bottom chords can be based on the same design principle, but may differ in details such as the cross-sectional geometry and / or area, especially since the bottom chord is primarily subjected to tensile stress and the top chord is primarily, or at least also to a large extent, subjected to compressive forces. This structural design, in particular the use of flat material bent in an L-shape at least in some sections, which is used to form further profiles, also allows for a good compromise between material usage, strength, variability, and accuracy.It has been shown that a particularly advantageous arrangement can be provided if several (preferably only two) L-shaped flat material sections bent at the end are welded together to form a closed (square) profile.

[0072] The supporting structures of the longitudinal section modules 11 are in the Figuren 5A bis 5C The upper head module 11b is shown in combination with other (installed) components of the track system. The lower head module 11b has a comb plate, a base section, and several guides for chain rollers, step / pallet rollers, and / or handrails. Corresponding guide rails are also arranged on the intermediate module. The guide rails rest on structural sections (especially made of flat material) of the supporting structure. The upper head module has (in addition to the components already present in the lower head module and / or intermediate module) a drive for driving a chain and optionally also a handrail. Furthermore, the upper head module 11a has a balustrade 12 with a handrail 13 mounted on it; the balustrade is connected to the supporting structure, as shown in particular by... Fig. 5B visible.

[0073] The longitudinal section modules 11 each have reference points 17.1 or corresponding geometrically predefined (especially circular) reference recesses 17.3 embedded in the flat material on the supporting structures 15 or side wall units 17 or side walls 17a, 17b ( Fig. 5B ). In the Figuren 5A bis 5C The reference points 17.1 are partially covered by side support units 44 predefined / positionable on support and movement devices 40a, 40b, which are connected by means of coupling units 46 shown schematically here ( Fig. 5C ) are connectable to the reference points 17.1 (e.g., by means of plug-in coupling bolts, which connect without tolerance to the corresponding coupling points 45 of the support and movement devices 40a, 40b). By supporting (in particular suspending) the individual longitudinal sections at the corresponding integrally provided reference points 17.1, reference can be made to these positioning reference points 17.1 repeatedly and preferably exclusively, especially in connection with individual assembly and mounting steps, and also when positioning / aligning additional installation components. The reference points 17.1 are preferably formed during the manufacturing process of the side walls 17a, 17b on the corresponding structural section, particularly in the at least single-layer flat material, preferably by laser cutting, whereby, thanks to a comparatively high accuracy (especially with semi- or fully automated in-plane cutting, e.g.,(on a correspondingly precisely aligned worktable, during the material processing process) further recesses or cutouts introduced into the structural sections or the flat material are positioned / positionable with comparatively high accuracy with respect to reference points 17.1 and can therefore (optionally) also serve as a reference for the positioning / alignment of components (however, the first master reference is preferred, described here as the actual original reference points of the respective longitudinal section). This also applies in particular to the positioning of metal sheet connections 31 (. Fig. 5B ), which can be applied with force-fit / form-fit connecting means 37 for pairwise connection of the longitudinal section modules 11 (in particular manually), as well as for slots or the like further recesses for receiving or for predefined arrangement of further components of the track device 10 or further support structure elements (or flat material sections) such as individual support structure sections or support elements or crossbeams, in particular also in an arrangement orthogonal to the side wall plane. By means of the reference points 17.1 and in particular the one described here preferably around a reference axis Y17 formed by at least two of the reference points ( Fig. 5C The tiltable storage or suspension / holding of the longitudinal section modules 11 also ensures a comparatively precise alignment of the longitudinal section modules 11 relative to each other, particularly in connection with the paired connection / marriage of the modules (if their butt planes are aligned parallel to each other, especially in a connection plane predefined by a module connection process arrangement with at least an approximately vertical orientation), which, for example, also significantly facilitates the application of the sheet metal connections described here in combination with, for example, essentially manually inserted force-locking / form-locking connecting elements 37 (especially locking ring bolts) and further improves the feasibility of the modular concept described here.

[0074] The present invention also makes it possible in particular to overcome disadvantages and handling difficulties associated with escalators 3 ( Fig. 1 ) with standard construction, which requires an inclined arrangement / alignment of all longitudinal sections or of the supporting structure already created over the entire longitudinal extent during a comparatively long phase of the manufacturing process.

[0075] Each module can be supported against the ground at module-specific support points 11.11 provided on the supporting structure. These support points 11.11 can, for example, be located on the underside of the respective supporting structure, allowing the longitudinal section module to be placed on or supported independently of the reference points, thus further simplifying handling. For instance, the support points can also be used to temporarily store or transport the entire supporting structure after completion.

[0076] The supporting structure 15, or the corresponding side wall, can be provided with a tolerance-minimized (central, arranged at least approximately centrally between the upper and lower chords) height section 15.1, in which a comparatively high positional accuracy or a comparatively small tolerance can be ensured, particularly if the corresponding supporting structure section is preferably formed in one piece from flat material. In an upper height section 15a of the supporting structure, especially also in the area of ​​the balustrade attachment, a comparatively large tolerance can also be uncritical. This also applies to a lower height section 15b of the supporting structure, especially in the area of ​​a floor unit. In this respect, the present invention is also based on the concept of referencing this central height section 15 during relative and / or absolute positioning.1 to enable this by providing at least one, preferably at least two, structurally load-bearing reference recesses in this middle height section, e.g. designed for support on side support units.

[0077] The supporting structure 15, for example, comprises several structural sections 15.3 (in particular flat material sections) and several supporting structure units 16, each with several profiles 16.1 or profile sections 16.1a with a hollow cross-section (in particular sheet metal profiles or flat material profiles), e.g., square profile sections, L-profile sections, and / or U-profile sections. Individual surface sections or struts of the supporting structure units 16 can also be used to connect opposing side wall units. Optionally, several supporting structure units 16 together form a longitudinal section module, e.g., if the intermediate module is to be composed of several comparably constructed supporting structure units 16 or is to be designed to be scalable and extendable.

[0078] At two adjacent longitudinal sections of the supporting structure, particularly at the bend, recesses 16.2 (or a corresponding free space) can be structurally incorporated in the area of ​​a connection interface / plane. Adjacent side wall sections can preferably be connected to each other in a planar connection interface 18 by coupling corresponding interlocking contours, especially for subsequent material-bonded joining at the connection interface.For example, a positive-locking coupling is provided, in particular for defining a relative position for subsequent welding of adjacent longitudinal sections, by means of a first positive-locking contour on a first longitudinal section and a corresponding second positive-locking contour (in particular a negative form) on a second longitudinal section, whereby several individual flange plate couplings (planar, acting two-dimensionally) can also be provided at each connection interface, especially at the most widely separated vertical positions possible. This promotes high positional accuracy and reduces the risk of tilting / tightening.

[0079] The form-fitting contours described here also make it easier in particular to arrange the corresponding material sections on a worktable unit for the production of the side walls or side wall units or the supporting structure of individual longitudinal sections or modules.

[0080] For paired connection / marriage of the individual longitudinal section modules, a load-bearing module connection 30 is preferably provided, each comprising several sheet metal connections 31 with sheet metal angle units or plate units. The respective sheet metal connections 31 are preferably based on purely force-fit / form-fit connection technology, wherein the resulting holding force is preferably a frictional force, i.e., can be ensured without a form fit. Accordingly, the respective sheet metal connection 31 can, depending on the connection position, comprise one of the following connection components: butt plate 31.1, internal angle or plate 31a (in particular a bent angle piece), angle / angle piece 31b (in particular in a bent design), counter plate 32.The individual connecting components are joined to one another by means of connecting elements 37 (in particular screw connections or rivet connections) in a form-fit / force-fit manner, in particular such that the supporting structures of the adjacent longitudinal section modules are held against each other by friction. For this purpose, fastening axes 34 are provided, which are defined by the sheet metal connection and the supporting structure, in particular by several (through) holes or optionally at least partially also by fastening holes designed as elongated holes (in particular over-dimensioned in the axial longitudinal direction for positional adjustment). Screws and / or rivets (for example in the form of locking ring bolts) are suitable as connecting elements 37, wherein a lock nut or a comparably acting counterpart (e.g. of a locking ring bolt connection) is preferably also provided in each case.

[0081] A longitudinal section module connection arrangement 40 (or module connection process arrangement) enables the individual longitudinal section modules to be connected / married, whereby handling and relative positioning can be advantageously carried out. The respective longitudinal section module can be supported against the ground by means of support and movement devices 40a, 40b or correspondingly acting supports (assembly aids) (in particular first and second support and movement devices 40a, 40b per longitudinal section module), wherein a lifting or...Tilting kinematics 41 can be integrated; a tilting device 42 enables movement in the form of a tilting about a transverse axis for positioning a desired longitudinal section, for example, for aligning a respective platform section at an angle in order to position the corresponding inclined section horizontally against the adjacent intermediate module. The support and movement devices 40a, 40b can be mounted on wheels or rollers 43. The support and movement devices 40a, 40b can preferably also each include side support units 44, by means of which the respective module can be supported and positioned with minimized tolerances via reference recesses provided in the side wall units. For this purpose, predefined coupling points 45 arranged with high accuracy can be provided on the side support unit 44, to which coupling units 46 (e.g., plug-in coupling bolts) can be coupled.Depending on the preferred configuration of the assembly process, the longitudinal section module connection arrangement 40, or a corresponding section of an assembly line 100, can include further positioning units 50 (in particular equipped with guides or plug connections 53 on alignment plates), wherein the respective side support unit 44 preferably couples to a correspondingly provided positioning unit 50 in a standardized manner, optionally directly or via the support and movement devices described here. In other words, the side support units 44 can optionally be designed as comparatively slim side arm levers (e.g., also individually for each type of travel device), and the positioning units 50 can, for example, be provided as largely standardized assembly aids by means of which support is provided on the ground.This further reduces the effort required for any desired type-specific adaptation of assembly aids.

[0082] The longitudinal section module connection arrangement 40 is preferably provided as part of an assembly line 100 for the assembly of support structures of modularly constructed travel path devices (in particular, process / production lines), namely in the end area of ​​this assembly line 100, on which the individual longitudinal section modules are preferably already arranged and supported in the intended sequence and optionally also in an orientation optimized for connection during a phase of module-specific assembly. The assembly line 100 can also include one or more alignment devices 101 (e.g., also floor-mounted rails), and / or optionally at least one side stop 101.1. The assembly line 100 has a horizontal support (in a direction transverse to the longitudinal extent of the respective module), which is preferably configured to interact with the side support units 44 (in particular without the need for rails or similar floor-mounted guides), so that positioning in the transverse direction via the module-specific integral reference points can also be achieved using comparatively slim assembly aids. For example, a clamping mechanism (clamping connection) allows individual assembly aids to be temporarily held / fixed. Optionally, the assembly line 100 also includes a spatially planned cavity or...a free space for assembly 110 below the alignment / support plane of the respective intermediate module, in particular a free space below ground level, so that the intermediate modules can also be advantageously arranged flat above the ground when oriented horizontally (both for the module-specific assembly and for completing the entire supporting structure by connecting / marrying the individual modules).

[0083] The following geometric references facilitate the understanding of the present invention: horizontal position / orientation Pxy of the pedestal section of the corresponding head module; inclined position / orientation Pα of the pedestal section of the corresponding head module; distance between the reference point or reference recess and the mounting point (in particular, distance in the side wall plane); butt plane E11; crossbar plane; connection plane E18 defined by the connection interface of coupled modules; connection plane E30 defined by the module connection process arrangement; predefined mounting axis / direction X100 (axial orientation of a mounting line);

[0084] The term "butt plane" refers to an end face of the respective module, defined at least by the load-bearing structural ends, where a connection is provided in a butt joint arrangement with the adjacent module. The term "connection plane," in a narrower sense, also in a mathematical / geometric sense, refers to a plane in which the applied fastener is to be located or at least act. Therefore, multiple fasteners can be provided, axially overlapping the butt plane(s) and arranged in several connection planes, e.g., parallel and / or orthogonal to each other, or acting within these planes.

[0085] The following outlines the individual process steps in a chronology advantageous to the process described here: The material intended for the construction of the supporting structure, particularly in the form of flat material, undergoes material processing (step S1) including the creation of a material recess, especially by laser cutting; this processing step is preferably carried out with the flat material arranged on a worktable. This allows, in particular, the production of the essential sections of the respective side wall (unit). Subsequently, a material-bonded joining process (step S2) is carried out, in particular by welding, with the flat material arranged similarly (on the same worktable).For example, butt welding can also be performed in the area of ​​the bend, particularly after the corresponding adjacent longitudinal sections of the relevant head module have been positively positioned relative to each other using appropriately incorporated positive-locking contours. Subsequently, a module-specific assembly (step S3) of at least the most important supporting structure components (side wall units or at least side walls and crossbeams) can take place, optionally in the same plane or on the worktable (or its extension) that was used for steps S1 and / or S2. Following this, arrangement and alignment (or...) preferably takes place.(a relative positioning) of several modules (step S4) such that the modules can remain in the chosen relative arrangement to each other during the further course of the production process, i.e., they are already arranged in a row in such a sequence that the entire supporting structure can be assembled without further repositioning of the individual modules in the longitudinal direction (no change of sequence along the assembly line). Now, module-specific handling and module-specific assembly can first take place (step . S5 ) of, for example, built-in components, wherein the respective module is advantageously oriented, in particular in a horizontal plane (head modules with their platform section in a horizontal orientation). Subsequently, a preferably positive-locking / force-locking connection of several modules can be achieved (step S6) to form the supporting structure of the entire track system, whereby the head modules are preferably only tilted about a reference axis to align the inclined section of the respective head module in a horizontal plane in which the intermediate module is preferably arranged / remains. Subsequently, the track system can be completed (step S7 ) e.g. by further assembly measures, for example concerning the balustrade or a completion of surrounding drive or handrail components or an installation of the steps (the latter can optionally also be done module-specific).

[0086] Steps S4 to S6, and optionally S7, are preferably carried out in the same assembly line, i.e., with the individual modules in the same order and aligned in the longitudinal direction of the assembly line. Steps S4 to S6 preferably utilize reference recesses integrally provided in the respective module-specific support structure, with these reference recesses preferably being created in step S1, each specific to the module.

[0087] The following section explains special features of the invention with reference to individual figures or embodiments.

[0088] In Fig. 1 Figure 3 illustrates a conventional orientation of an escalator in the shape of a horizontal Z. However, this orientation makes many assembly and handling processes more difficult.

[0089] In the Fig. 2A, 2B The two head modules 11a, 11b of a modularly deployable travel path device are shown in an arrangement supported on support and movement devices 40a, 40b and with the respective platform section 11.1 in at least an approximately, preferably exactly, horizontal orientation (horizontal plane Exy). In this arrangement / orientation, the installation of drive components or other components is considerably facilitated.

[0090] Fig. 3 This illustrates, among other things, the procedural advantage associated with the present invention of an advantageous arrangement / alignment of the individual modules, both during a phase of module-specific assembly / mounting and also already in / for an assembly line 100 for the assembly of the entire support structure or the complete track system. In the Fig. 3 In the relative arrangement shown, the individual modules remain accessible from the front and advantageously aligned (especially exactly horizontally). Nevertheless, the modules can be moved into a final relative position through a comparatively streamlined process involving a relatively short translational movement (x) and a tilting (head modules), particularly around the reference axes (y) provided integrally by the side wall units as described here, and held there with comparative precision (as, for example, in the Fig. 6 (relative position shown).

[0091] From the Fig. 4A, 4B, 4C Further details of the supporting structure 15 of the respective modules 11a, 11b, and 11c are shown. The structural features are already described in detail elsewhere; therefore, no further information regarding the Figuren 4 It should also be mentioned here that the connection of the individual longitudinal section modules to form the entire supporting structure can optionally be carried out in the raw state of the module-specific supporting structures or with already installed components, depending on the desired process configuration. The pairwise connection / marriage of adjacent modules is achieved by means of the sheet metal connections described here, particularly at least in the area of ​​the respective top / bottom chord, preferably in at least two fastening levels, preferably in a form-fit / force-fit manner such that the sheet metal connections connect the modules to each other by friction / force-fit.

[0092] From the Fig. 5A, 5B, 5C Further details regarding the overall structure of the track device and its installation components connected to the support structure 15 are evident with reference to the respective modules 11a, 11b, and 11c. The associated design and procedural advantages of the present invention are already described in detail elsewhere; therefore, with regard to the Figuren 5 It should also be mentioned here that the relative arrangement and alignment of the individual modules for connecting / marrying them can optionally be carried out using the floor-mounted rails 101 shown here, or alternatively using side stop units 101.1 or similar assembly / alignment aids. It is worth noting that assembly aids that extend above the modules in height or are mounted overhead on the ceiling of a machine hall are not necessarily required; that is, the entire supporting structure can be assembled solely on the ground or supported against the ground (see also the description of the longitudinal section module connection arrangement 40).

[0093] Regarding the Figuren 4 and 5It is worth noting that the respective side wall can optionally be designed entirely as a flat material section with recesses incorporated into it (e.g., laser-cut recesses that create an X-arrangement of diagonal strut sections, e.g., a laser-cut X-contour), or it can feature diagonal struts designed as welded profiles (especially bent U-profiles) that interact with the flat material or are integrated into the structure via flat material sections. A combination of these two alternative designs along a single module or individually for each module along the entire track system is also possible. This option for variation also applies in particular to the [specific examples would be inserted here]. Figuren 4B , 5B The illustrated designs and examples shown.

[0094] In Fig. 6 Individual modules 11a, 11b, 11c, 11c' of a travel path device 10 are shown in a phase of the assembly process in which the adjacent and interconnected joint planes are already aligned parallel to each other, in particular by tilting the head modules 11a, 11b about the reference axes integrally provided by the side wall units of the respective module and supported on the support and movement devices 40a, 40b, optionally using a lifting / tilting kinematic 41, which can be activated or actuated, for example, by means of a tilting device 42 provided on the respective support and movement device. Optionally, a hoist can also be provided, depending on the equipment of a machine hall.Advantageously, the tilting device(s) 42 indicated here can ensure handling even without a crane or load transfer devices arranged above the modules; this also increases variability / flexibility and occupational safety, thus reducing the safety requirements placed on the process.

[0095] In Fig. 7 Seven steps of a process for creating a guideway device described herein are explained by way of example, wherein the present invention is primarily based on steps S5, S6, and S7, in particular step S6. First, material processing takes place (step S1 ) comprising a material recess, in particular by laser cutting, especially concerning the essential sections of the respective side wall (unit). This is followed by a material-bonded joining process (step 1). S2) especially of flat material sections. Following this, a module-specific assembly can already begin (step 1). S3 ) at least the most important load-bearing structural components (side wall units or at least side walls and crossbeams). This is preferably followed by the arrangement and alignment (or relative positioning) of several modules (step 1). S4 ) such that the modules can remain in the chosen relative arrangement to each other during the further course of the production process, in particular with the intermediate module and the respective platform section in a precisely horizontal orientation. Now, module-specific handling and module-specific assembly can first be carried out (step S5 ) of, for example, installation components; in particular, drive components and guide rails are mounted. Subsequently, a preferably positive-locking / force-locking connection of several modules (step ) can be achieved. S6) to form the supporting structure of the entire track system, whereby the head modules are preferably only tilted about a corresponding reference axis Y17 to align the joint plane of the respective module, in particular in an at least approximately vertical connection plane. The positive / force-fit connection can be effected by means of optionally pre-assembled sheet metal connections 31, particularly in the area of ​​the respective upper / lower chord 17.7, 17.9; for this process, the respective module can remain arranged on the support and movement devices 40a, 40b of the longitudinal section module connection arrangement 40 described here and be held in position by means of the corresponding lifting / tilting actuators (bearing about the corresponding reference axis Y17). In particular, the head module is first connected to the adjacent intermediate module ( Fig. 8B ), and then at least one more module with this intermediate module ( Fig. 8C ). Following this, the path device can be completed (step 1). S7 ) e.g. by further assembly measures, for example concerning the balustrade or the completion of surrounding drive or handrail components or the installation of the steps.

[0096] Steps S4 to S6 and optionally also S7 are preferably carried out in the same assembly line 100, with the individual modules in the same sequence and aligned in the longitudinal direction X100 of the assembly line, whereby reference is made to the reference recesses provided integrally in the respective module-specific support structure during alignment, support and positioning; in addition to the support and movement devices 40a, 40b described here, the longitudinal section module connection arrangement 40 has, for example, only floor-mounted or otherwise floor-bound guides or side stop units or similar assembly aids for adjusting the aligned longitudinal alignment for all modules.

[0097] Regarding step S6, this step or process can be subdivided into the following steps, which are explained in detail here using the example of final assembly of the support structure without the use of a pit: Step S6.1 (optional: attaching adapter plates), Step S6.2 (arranging / tilting the lower head module), Step S6.3 (optional: inserting / placing the lower head module into adapter plates), Step S6.4 (connecting / marrying the lower head module with the adjacent intermediate module), Step S6.5 (arranging / tilting the lower head module together with the intermediate module), Step S6.6 (arranging / tilting the upper head module with its inclined section aligned with the longitudinal extent of the intermediate module), Step S6.7 (optional: inserting / placing the upper head module into adapter plates on the intermediate module, or vice versa), Step S6.8 (connecting / marrying the upper head module with the intermediate module).

[0098] In the event that a pit can / should be used, the corresponding steps can be varied accordingly, in particular with regard to the orientation of the intermediate module and the height position of the head module; advantageously, only step S6.5 is adapted by arranging the lower head module together with the intermediate module without tilting the lower head module and intermediate module, because the upper head module can be arranged flush (in particular strictly horizontally) with the intermediate module with its inclined section, without having to adjust the orientation of the intermediate module; in this case, the height position of the upper head module does not have to be noticeably changed either.

[0099] From the Fig. 8A, 8B, 8C The individual handling steps for step S6 are shown: the modules 11a, 11b, 11c, which are each mounted in the support and movement devices 40a, 40b aligned in the assembly direction X100 on the assembly line 100, are initially spaced apart from each other. They are then mounted in pairs adjacent to each other by translation and tilting (swiveling) at least the respective head module 11a, 11b about the corresponding reference axes Y17 provided by the side wall units 17, which are specific to the module. The individual support and movement devices 40a, 40b can be positioned axially relative to each other, e.g., by means of spacers; optionally, a transverse alignment is also carried out before or after this, e.g., with reference to a fixed point in the machine hall (e.g., a door frame).

[0100] In Fig. 8C The module connections 30 and the individual sheet metal connections 31 already mounted between head module 11a and intermediate module 11c are indicated. It should merely be mentioned here that the connecting means 37 described here can be mounted manually and / or at least partially with robotic assistance in the direction of the respective mounting axis 34, particularly in at least an approximately horizontal and in an at least approximately vertical direction, e.g., by applying a tool for fixing locking ring bolts.

[0101] In Fig. 9 An assembly line 100 is shown, on which three groups of longitudinal section modules are arranged in a row in the intended sequence. Fig. 9 The diagram therefore shows three phases, whereby the connecting / marrying of the modules (step S6) only takes place in the third phase shown, i.e., after relative arrangement and alignment (step S4) and module-specific assembly (step S5) have been carried out. For step S6, it is advantageous if the head module can be pivoted with its free end into a floor recess or pit 110, especially since the entire horizontal working plane Exy can then remain comparatively low for the entire assembly process (i.e., also for preceding steps).However, such a ground-based device is not necessarily required; alternatively, the support and movement devices 40a, 40b of the longitudinal section module connection arrangement 40 may also have lifting devices which enable the horizontal working plane Exy to be raised, in particular in such a way that the free end of the downwardly pivoted head module remains above the ground.

[0102] In the Figuren 10A bis 10E The individual phases of step S6 are illustrated; first, according to sub-step S6.1, adapter plates are attached, in particular to two reference recesses each, at least on the intermediate module 11c; then, according to sub-step S6.2, Fig. 10A, 10B The lower head module 11b is positioned / tilted until its inclined section is horizontally aligned; then (optionally) according to sub-step S6.3, the lower head module is inserted / placed into adapter plates on the intermediate module 11c, or vice versa – alternatively, this sub-step is performed without the use of adapter plates; then, according to sub-step S6.4, the lower head module 11b is connected / married to the adjacent intermediate module 11c; then, according to sub-step S6.5, Fig. 10C, 10D an arrangement / tilting of the lower head module 11b together with the intermediate module 11c; then, according to sub-step S6.6, Fig. 10D an arrangement / tilting of the upper head module 11a with its inclined section aligned with the longitudinal extent of the intermediate module 11c; then, according to sub-step S6.7, Fig. 10E an insertion / placement of the upper head module 11a into the adapter plates mounted on the reference recesses of the side wall units of the intermediate module on the intermediate module 11c, or vice versa; then proceed according to sub-step S6.8 according to Fig. 10E a connection / marriage of the upper head module 11a with the intermediate module 11c. It is worth mentioning that in sub-step according to Fig. 10D Advantageously, adapter plates can be used which are designed in such a way that guide pins mounted on the corresponding head module can be used as counter-coupling components; in this way, a situation-dependent or process-adapted retrofitting of assembly aids can be carried out on the respective module in a simple manner without elaborate assembly aids, depending on whether it is necessary or advantageous or not (here, for example, depending on whether a pit can / should be used).

[0103] In the Figuren 11A bis 11F An advantageous embodiment of support and movement devices 40a, 40b is described. A traverse boom 51 rests on supports 57, which are positioned on one or more of the respective positioning units 50 by means of mounting brackets 55. The respective traverse boom 51 can advantageously be formed by angle profiles 51.1 (L- or U-profiles), particularly in a welded construction. Structurally reinforcing flat bars 51.3 or similar load-bearing devices (e.g., welded-on 8 mm flat bars) can be provided on the upper side (support) of the respective traverse boom 51.

[0104] For example, the crossbeam arms 51 provided for the respective upper head module are formed from laser-cut L-angles made of 8 mm steel sheet, which are welded together. This design is particularly advantageous in connection with the requirement that the upper head module, due to the downward-facing bevel (kink point), should be arranged higher on the respective positioning unit 50 than the corresponding lower head module and the intermediate module. For the latter, the respective crossbeam arm can advantageously (alternatively) also be formed by a U-profile, in particular from laser-cut 8 mm sheet.

[0105] The respective truss boom rests loosely on the corresponding support 57 without additional fixing; the respective mounting bracket 55 is connected to the support, e.g. screwed on, and prevents the truss boom from slipping / shifting.

[0106] The corresponding side support unit 44 can also be manufactured as a laser-cut L-angle from, for example, 8 mm sheet metal and connected to the crossbeam, in particular by bolting. The through-bolts 46, already described elsewhere, which act in the respective corresponding reference recess 17.3 of the respective module, prevent relative displacement of the respective module.

[0107] The components of the respective positioning unit 50 described here can be provided at advantageously low production costs, especially if these components are all made of, for example, 8mm sheet steel; in this respect, minimal setup effort can also be ensured.

[0108] In the Fig. 12A, 12B, 12C The application of one or more adapter plates 60 is illustrated in detail; each adapter plate 60 is attached to two reference recesses of a respective side wall of the corresponding module by means of paired coupling points, so that the guide 61, which converges / tapers in the longitudinal direction of the module, leads to a / the desired coupling point 65a defined by the end position of the guide; the end position (target position for the corresponding reference recess of the adjacent module or a reference bolt mounted on it) is indicated here by a dashed circle ( Fig. 12C The adapter plates 60 can be used for the desired axial positioning; optionally, the corresponding reference bolts can also have a shoulder or similar reference edge, by means of which a positioning reference can also be provided in the transverse direction, in particular relative to the inside or outside of the adapter plate.

[0109] In particular, when considering the figures together with the present description, the concept according to the invention becomes apparent in the overall context of the manufacture of travel path devices (especially escalators), making it clear how an advantageous symbiosis of process features and design characteristics can be realized, which also facilitates the final assembly and handling of the support structure extending over the entire length of the travel path device in a comparatively streamlined process and with comparatively little equipment-related effort with regard to assembly aids.
