EP3024771B1 - Moving walkway pallet - Google Patents

Description

The invention relates to a moving walk according to the preamble of claim 1. Such a moving walk is off US2007 / 036626 A1 disclosed. The pallet band of a moving walk can be entered via access areas that connect to the two deflection areas. Moving walks usually have due to the construction of their deflection on a large starting height of their entrance areas. So that the users do not have to run over a too large or too long ramp to the starting height, a pit is provided in the ground at least in the deflection. In these pits, the largest part of the deflection can be sunk, so that the pallet band can be entered almost at ground level. The pallet belt usually has two link chains serving as traction means, between which the traveling platform pallets are arranged. These link chains are guided in the deflection over Umlenkkettenräder. The large starting height of the deflection regions is due in particular to the required pitch circle diameter of the Umlenkkettenräder, thereby avoiding the known problem of polygonal effect of chain drives. The polygon effect in a chain deflection is limited according to the textbook (Dubbel Taschenbuch für Maschinenbau 17th edition, page G108 to G109) to a tolerable level when the sprockets have a minimum of 17 teeth, which determines the deflection radius at a certain chain link length. This measure severely limits the spatial design. Especially in the field of escalators and moving walks, whose chain link length is usually given by pallet length, the condition of a minimum of 17 teeth means an extremely inconvenient restriction. It limits, for example, with a chain link length of 200 mm, as is quite common in traction means of pallet bands, the deflection radius towards the bottom to about 540mm.

Although reveals the EP 1 876 135 B1 Solutions to eliminate the polygon effect on sprocket diameters below the required diameter. However, the length of the chain links of the traction means limits the minimum possible pitch diameter due to the minimum required chain pitch, so that always at least one chain link is in engagement with the sprocket.

To overcome this problem suggests the WO2006 / 003238 A2 a flat-building moving walkway, in which the moving pallets are deflected in a turning area, instead of providing deflection areas with the conventional deflection of the pavement pallets by 180 °. In order for the pavement pallets to be diverted to have a sufficient payload at an intended width of the pallet band, they are very long in relation to the intended direction of travel. The in the WO2006 / 003238 A2 However, the proposed solution has the disadvantage that the mechanical components of the pallet band in the deflection areas can be subjected to enormous acceleration and deceleration forces. As a result, they are considerably more stressed than in a conventional deflection of the moving pallets. Furthermore, the abrupt change of direction of the moving pallets in the turning areas can lead to an uneven running of the entire pallet band. In addition, the proposed turning region of the pavement pallets requires separate tracks of the leading rollers to the trailing rollers of a pavement pallet to control the passage of each pavement pallet through the turning area. As a result, the overall width of the moving walk is increased or the conveying width of the pallet band is limited.

Object of the present invention is to obtain a flat-building moving walkway, which has a quiet ride, which builds slim in relation to the width of its pallet band and the pallet band components are moderately stressed in the deflection.

This object is achieved by a moving walk with two deflection areas and with a circumferentially arranged between the deflection pallet band, which has two traction means and a plurality of identical pavement pallets. The pavement pallets are hinged to each other and arranged between the two traction means. The mutually following pavement pallets are pivotable relative to each other about their pivot axes in the deflection. Each of the pavement pallets includes at least one body extending continuously between the traction means. Under the feature continuously extending body is a body to understand that extends without interruption between the two traction means, so is self-supporting and not just a local reinforcement of the pavement pallet serves. A continuously extending body does not necessarily have may be one piece, but may also consist of several assembled components. The main body has a base surface for attachment of at least one Trittelements, wherein the base length of the base surface in the intended direction of travel of the moving pavement pallet extends and the width of the base surface extends orthogonal to the intended direction. Due to the articulated connection to an immediately following moving pavement pallet, a pivot axis extending in the width is defined for the base body. This pivot axis is arranged in a plane containing the base surface or above the side of this plane facing away from the base body. Furthermore, the base body along its width on a base body cross-section, the geometric center of gravity is arranged below the base surface.

The basic bodies are articulated to each other by means of the traction means, wherein the traction means can have the articulation points which include the pivot axes.

By this body with high scheduled pivot axis in the plane of the base surface or above the base surface, a pavement pallet can be created, the tread element can be deflected when circulating in the deflection on the pitch circle of the Umlenkkettenrades or even on a smaller circular path than the pitch circle. Regardless of whether a Umlenkkettenrad without compensation of the polygon effect or a Umlenkkettenrad according to the EP 1 876 135 B1 is used with a compensation of the polygon effect can be reduced even more by the basic body according to the invention, the starting height between serving as a foundation or foundation ground and the tread element located in the entrance area.

The main body may have a width extending body cross-section with an outer contour, which is adapted to the position of the pivot axis of the body, and based on each existing spaces of the deflection, by the outer contours of the same shape body cross sections of an immediately preceding and immediately following, pivoted in the deflection basic body the pallet band is limited. As a result, the main body has a basic body cross-section extending over its width, which has the highest possible moment of resistance in terms of bending and torsion of the basic body, without obstructing the deflection of the moving-platform pallets in the deflection region.

In order to create a sufficient clearance for pivoting the pavement pallets and to maximize the moment of resistance of the body, the body cross-section is preferably triangular or trapezoidal. In conventional widths of the pavement pallet of 800mm to 1500mm and a pitch diameter of the Umlenkkettenrades from 200mm to 400mm, a sufficient modulus can be achieved if starting from the base surface, the base height of the triangular or trapezoidal body cross section is 0.5 to 2.5 times the base body length of the base surface. A particularly good matching of the basic body cross section to the existing space in the deflection region is given when the basic body height of the triangular or trapezoidal basic body cross section is 0.65 to 1.5 times the basic body length of the base surface. The larger the ratio of the main body height to the main body length, the further the geometric center of gravity of the main body cross-section is arranged away from the base surface.

The triangular or trapezoidal body cross-section preferably has an internal angle between 35 ° and 85 °. This inner angle lies between a first side limb adjoining the base surface and a second side limb adjoining the base surface, wherein the side limbs are arranged tapering starting from the base surface. In order to make the best possible use of the available space in the deflection region in order to achieve a high resistance torque, it is particularly preferable to choose an internal angle of 50 ° to 65 °.

With respect to the outer contour of the basic body cross-section, the two side legs can be designed differently long. But they can also be arranged mirror-symmetrically to a central longitudinal plane which extends in width and orthogonal to the base surface and the base surface cuts in the middle. Due to the mirror-symmetrical arrangement, the main body can be inserted into the pallet band without regard to the running direction. The two side legs must be starting from the base surface, not necessarily straight, they may also be concave or convex.

So that the individual base bodies are as light as possible, the widthwise extending side surfaces of the side legs and / or the base surface may have recesses.

The main body can be cast, for example, or made of an extruded profile.

In one embodiment of the invention, the base body is made of a metal sheet. The sheet may be, for example, aluminum, steel, brass, copper, bronze or stainless steel. The settlement of the body is first cut or punched out of the sheet, which also equal to the recesses can be made. If the development is punched, their recesses can be provided with circumferential collar, and other areas are reinforced by beads. Thereafter, the triangular or trapezoidal body cross-section can be formed by means of extending parallel to the width of the base surface extending bends.

The widthwise extending sheet metal end edges of the above-described body made of sheet metal, for example, may be arranged overlapping each other and having an interconnected area. To connect the Blechendkanten are all known types of welded joints, but also a crimping of Blechendkanten or a compound thereof by clinching. Since the base body is a bending support and, when used as intended, its base surface assumes the function of an upper belt of the bending beam, the area of the triangular or trapezoidal cross-section which is farthest from the base surface serves as a lower belt. Due to the trapezoidal or triangular cross-section of the body of this lower chord is significantly shorter than the upper chord. Therefore, the arrangement of the interconnected Blechendkanten in the region of this lower chord is particularly advantageous because the overlapping of Blechendkanten at this point a load-bearing material accumulation is created. Furthermore, the side legs and / or the sheet metal end edges of the main body can also be connected by further parts such as frames, intermediate plates and the like.

Of course, the widthwise extending sheet metal end edges of the main body can also protrude into the inside of the main body to increase, for example, the dimensional stability of the base surface. Another possibility is that the widthwise extending Blechendkanten are arranged in the base surface. At least one tread element can be fastened to the base body, wherein the tread element length extends analogously to the base body length of the base surface in the intended running direction of the moving walkway pallet. If the basic body length of the base surface corresponds to 0.6 to 0.95 times the tread element length of the at least one tread element to be fastened, a meshing overlap can be created between the tread elements. As a result, in the accessible area of the pallet conveyor, dangerous gaps that are narrowing over the accessible transport path of the moving walkway between adjacent moving walkway pallets can be avoided.

Of course, the base body can also be made of fiber composites and, for example, carbon fibers, aramid fibers and / or glass fibers. A manufactured from fiber composites base body is wound or woven and therefore has a continuous outer contour with a triangular or trapezoidal cross-section. As a result, an extremely lightweight and durable base body can be produced. The feature of a continuous outer contour is to be understood as meaning a tubular cross section of the basic body, wherein this tubular basic body may have exemptions and recesses. Such a base body could be wound on a mandrel, wherein the recesses are produced by a suitable guidance of the fibers in the base surface and / or in the side surfaces of the side legs.

A large number of identical pavement pallets of the moving walkway according to the invention is arranged between the two traction means and articulated to each other via connection points with the traction means and thereby formed with the traction means a pallet strip. As a result of the articulated connections, pavement pallets arranged below one another are pivotable relative to one another about their pivot axes in the deflection regions. Each of these moving pavement pallets contains at least one main body extending continuously between the two traction means of the pallet strip. The main body has a base surface for attachment of at least one Trittelements, wherein the base length of the base surface in the intended direction of travel of the moving pavement pallet extends and the width of the base surface extends orthogonal to the intended direction. Due to the articulated connection to an immediately following moving pavement pallet, a pivot axis extending in the width is defined for the base body. The pivot axis is in one containing the base surface Plane or above the, the main body facing away from this level arranged. The main body has along its width a base body cross-section, the geometric center of gravity is arranged below the base surface. Furthermore, each traveling platform pallet comprises at least one tread element which is fastened on the base surface of the basic body.

The pallets described above can be used not only in new, flat-building moving walkways, but also in conventional driving platforms with pits. Of course, an old moving walkway can also be modernized and its running rails and deflection areas optionally adapted to the new pallet band.

The at least one tread element may have projections formed on the tread elements, which projections project into the base body through recesses in the base surface after the tread element has been placed on the base surface. The at least one tread element can be fastened to the base body by at least one of the following fastening options, such as by caulking or riveting the projections, by means of screws, by means of clinching or by means of an adhesive. Particularly suitable adhesives are pasty or liquid one-component adhesives / sealants based on silane-modified polymers which crosslink by atmospheric moisture to form an elastic product. These are used, for example, in body and vehicle construction, wagon construction and container construction and in metal and apparatus engineering.

A particularly simple fastening variant of the tread plates on the base body is that on at least one tread element projections are formed which protrude after placing the Trittelements on the base surface by recesses in the base surface and the tread element is fixed by means arranged on the projections spring washers on the base body. Preferably, the position of the recesses described above in the side surfaces of the side legs is matched to the position of the projecting through the base surface projections. Although the size of the recesses is matched to the diameter of the spring discs, the projections can be fitted through the recesses through the spring discs.

FIG. 1 shows in side view in a schematic representation of a moving walkway 10, which is arranged on a supporting structure 50. As a supporting structure 50 is for example a floor or concrete foundation, which has sufficient strength. Of course, a steel frame, a steel beam, a concrete ramp and the like may serve as a supporting structure. The floor has receptacles 51 to which the components of the moving walk 10 are attached. These components include a first deflection region 11 and a second deflection region 12, as well as between the deflection 11, 12 arranged support structures 13, rails 14, balustrades 15 and a pallet 16. In the deflection 11, 12 are Umlenkkettenräder 19, 20 rotatably mounted and the Pallet strip 16 is circulating around this Umlenkkettenräder 19, 20 guided. Accordingly, the pallet band 16 forms a user-accessible forerunner 21 and a return 22 for returning the moving-platform pallets. Further, the deflection areas 11, 12 then ramps 17, 18 are arranged, via which the user can reach the entrance height H and enter the pallet band 16 or leave. From the FIG. 1 is clearly seen that in the absence of pit in the supporting structure 50, the distance or the starting height H between the supporting structure 50 and the lead 21 of the pallet strip directly affects the slope and the length of the ramps 17, 18 and thus, of course, the user comfort.

Below are the Figures 2 and 3 described together. FIG. 2 shows a schematic representation of the Umlenkkettenrad 20 of the deflection region 12 of the FIG. 1 Each main body 31 has a base surface 33 for attachment of at least one Trittelements 32, wherein the basic body length L of the base surface 33 in the space provided in the side view and a part of the pallet strip 16 with a plurality of pavement pallets 30 shown in section Running direction X of the moving walkway pallet 30 extends. The width B of the base surface 30, shown in the FIG. 3 , extends orthogonal to the intended direction X.

The FIG. 3 shows in three-dimensional view part of the in FIG. 2 shown pallet strip 16 with two traction means 35, on which rollers 37 are arranged in the articulation points described below. The continuously extending main body 31 have frontal connection points 49, through which the base body 31 are connected to the traction means 35.

The moving platform pallets 30 of the pallet band 16 are arranged below one another between the link chains serving as traction means 35 and connected to one another via the traction means 35. Due to the cut representation, is in the FIG. 2 only one of the two traction means 35 visible. The traction means 35 has articulation points 36, wherein in each case one articulation point 36 is arranged between two adjoining traveling-platform pallets 30 and a pivot axis SA, SB is defined by this articulation point 36. The simplest way to explain the assignment of the swivel axes SA, SB using the example of the pavement pallets 30 designated PA and PB. Assuming a running direction X of the moving pavement pallets 30 or a direction of rotation U of the reversing sprocket wheel 20, pavement pallet PB follows the pavement pallet PA. If the pavement pallet PA as shown, the Umlenkkettenrad 20 reached, this is pivoted relative to the moving pavement pallet PB to its associated pivot axis SA. Accordingly, the following pavement pallet PB is associated with a pivot axis SB, which is defined by the hinge point 36 between the moving pavement pallet PB and this subsequent, not shown pavement pallet.

The minimum possible pitch circle diameter D of Umlenkkettenrades 20 should not be exceeded due to the minimum required chain pitch. In order to further reduce the starting height H, the pivot axis SB of the moving pavement pallet PB is arranged at a distance k above a plane containing the base surface 33 of its main body 31. As a result, the base surfaces 33 move in the deflection region 12 on a deflection path whose diameter is smaller than the minimum pitch circle diameter D of Umlenkkettenrades 20. Of course, the distance k can also be 0, wherein the orbit of the base surfaces 33 approximately corresponds to the pitch circle diameter D. Assuming that the tread element thickness v of the tread element is not changed, the starting height H decreases, the greater the distance k is selected. The distance k can be selected by designing the connection points 49 described above.

So that the moving pavement pallet 30 has sufficient flexural stiffness, its main body 31 has, along its width B, a basic body cross section whose geometrical center of gravity S is arranged below the base surface 33 at a center of gravity distance t. Preferably, the center of gravity distance t is as large as possible. This can be achieved by means of a basic body 31, whose main body cross-section extends as far as possible into the space below the base surface 33. As the FIG. 2 shows, this space or free space is limited in particular in the range of Umlenkkettenrades 20. Preferably, the continuously extending main body 31 therefore has a basic body cross section whose outer contour is adapted to the position of the pivot axis SA, SB of the main body 31, and based on each existing spaces of the deflection 11, 12, by the outer contours of the same shape body cross sections of an immediately preceding and immediately subsequent, pivoted in the deflection region 11, 12 basic body 31 of the pallet belt 16 is limited.

The basic body cross section of the in the FIG. 2 illustrated embodiment is Trapezoidal, so that the base body 31 can not collide with an axis 25 or shaft 25 of the Umlenkkettenrades 20 and adjacent, the same shape bodies 31. The trapezoidal cross-section of the main body 31 is formed from a sheet metal by means of bends extending in the width B, whereby a first side limb 41 and a second side limb 42 are formed by the folds, which adjoin the base surface 33 and extend from the base surface 33, extending to each other. The two side legs 41, 42 are arranged in the present embodiment at an internal angle α of about 55 ° to each other. The size of the inner angle α can be dependent on the ratio of the basic body length L to the basic body height N or the standard height N of the basic body cross section and the pitch circle diameter D of the Umlenkkettenrades 20.

The sheet-metal end edges 38, 39 extending in the width B are arranged overlapping in a plane parallel to the base surface 33 and connected to one another. Preferably, the overlapping Blechendkanten 38, 39 are welded together by spot welding or seam welding. As a result of the overlapping and welding of the sheet metal end edges 38, 39, the basic body 31 subjected to bending is ideally reinforced in its lower belt zone. Due to its profiled tubular body cross section of the base body 31 is extremely resistant to bending and torsion.

From the FIG. 3 It can be seen that the base surface 33 and extending in the width B side surfaces of the side legs 41, 42 have recesses 43 in order to reduce the weight of the main body 31.

It should also be added that in the FIG. 3 shown basic body 30 may also be made of composite materials, in particular fiber composite materials. This would have no overlapping area, as in the FIG. 2 is shown, but a continuous outer contour, without extending in the width end edges. Such a profiled tube-shaped base body could comprise carbon fibers and / or aramid fibers and / or glass fibers. A basic body produced from composite materials may also have a trapezoidal or triangular basic body cross section.

FIG. 4 shows a part of a moving walkway pallet 130 in a three-dimensional bottom view a base body 131 having a triangular, extending in the width cross-section, wherein on the base 131 a tread element 132 is attached. The extending in the width B Blechendkanten 138, 139 of the body 131 are arranged in this embodiment in the base surface 133 of the body 131. Furthermore, projections 145 are formed on the tread element 132, which protrude after the application of the tread element 132 on the base surface 133 through recesses in the base surface 133. The tread element 132 is attached to the main body 131 by means of spring washers 146 arranged on the projections 145, also called spring axial securing devices, circlips or lock washers. Also this main body 131 has for the purpose of weight reduction recesses 147 in the side surfaces 143, 144 of its side legs 141, 142. In order for the spring washers 146 to be mounted, the position of the recesses 147 in the side surfaces 143, 144 coincide with the position of the protrusions 145 projecting through the base surface 133. Furthermore, the size of the recesses 147 is matched to the diameter of the spring discs 146.

FIG. 5 shows a sectional side view of another embodiment of a pavement pallet 230. This has a continuously extending base body 231 with a triangular body cross-section. The sheet-metal edges 238, 239 extending in the width B of the main body 231 protrude into the inside of the main body 231. The two lateral legs 241, 242 are arranged at an internal angle α mirror-symmetrical to a central longitudinal plane MM which extends in the width and orthogonal to the base surface 233 extends and the base surface 233 cuts in the middle.

The at least one tread element 232 has projections 245 formed on the tread elements 232, which protrude into the base body 231 through recesses in the base surface 233 after the application of the tread element 232 on the base surface 233 and position it on the base body 231. The at least one tread element 232 can be fastened to the basic body by various fastening variants, for example by caulking or riveting of the projections, by means of screws or by means of an adhesive. The basic body length L of the base surface 233 preferably corresponds to 0.6 to 0.95 times the tread element length T of the at least one tread element 232 to be fastened, whereby the tread element length T extends analogously to the main body length L of the base surface 233 in the intended running direction X of the moving platform pallet 230. As a result, the outer contour of the body cross-section as in FIG. 2 shown, fill the available space optimally.

Although the invention has been described by way of illustrating specific embodiments, it will be apparent that numerous other embodiments can be provided with the knowledge of the present invention, for example by combining the features of the individual embodiments and / or interchanging individual functional units of the embodiments. For example, per pavement pallet only a tread element may be attached to the base body, which extends over the entire width of the main body, or as from FIG. 3 it can be seen, several tread elements attached to the body. It is also possible that the main body is integrally formed together with the tread plate, for example, as one piece produced by die casting pallets. In this variant, the plane which contains the bottom view of the tread element and from which plane the side legs of the main body cross-section extend, is the basis. Of course, a pavement pallet may also have two continuously extending base body, which are arranged parallel to each other and are connected to each other by means of one or more tread plates.

Furthermore, the Blechendkanten can be connected to each other in all embodiments. Of course, all mentioned attachment variants of the tread elements on the main body can be used in all embodiments. It is also possible that the continuously extending main body has a basic body cross-section which deviates from the trapezoidal or triangular cross-sectional shape, for example by creating a polygonal cross-sectional shape by means of further folds.
