(54) Pladetransportbånd, navnlig til personbefordring.(54) Plate conveyor belts, in particular for passenger transport.
Opfindelsen vedrører et pladetransportbånd, navnlig til personbefordring, med efter hinanden anbragte, sammenhængslede plader, der drives sammen, og som danner et endeløst transportbånd, der udviser en vejstrækning, der mindst omfatter ét hældende plan, der er forbundet med et andet plan gennem en konveks, cirkelbueformet kurve.BACKGROUND OF THE INVENTION The invention relates to a plate conveyor belt, in particular for passenger transport, with consecutive, interconnected plates which are driven together and which form an endless conveyor belt showing a road section comprising at least one inclined plane connected to another plane through a convex , circular arcuate curve.
Ved de fleste kendte pladetransportbånd, navnlig sådanne som tjener til persontransport fra et horisontalt plan til et andet S horisontalt plan, sker kun forbindelsen mellem den skrå del af ^ transportbåndets nyttestrækning med det øverste plan gennem en kurve, v) Overgangen fra det nederste plan til det skrå plan gennemføres i almindelighed ved hjælp af en fast kamplade, der i det mindste del-In most known plate conveyor belts, especially those which serve for passenger transport from one horizontal plane to another S horizontal plane, only the connection between the inclined portion of the conveyor belt's utility line with the upper plane passes through a curve; v) The transition from the lower plane to the oblique plane is generally accomplished by means of a fixed camplate which is at least partially

[- έ 3 2 144330 vis har en hældning svarende til transportbåndets. En sådan indretning tilfredsstiller de bestående sikkerhedsforskrifter med hensyn til transportbånd, som transporterer personer, der medfører genstande i transportmidler, således som det f.eks. er tilfældet i selvbetjeningsbutikker, hvor kunderne anvender indkøbsvogne.[- έ 3 2 144330 has a slope corresponding to that of the conveyor belt. Such a device satisfies the existing safety regulations with regard to conveyor belts which carry persons carrying articles in means of transport, such as for example. is the case in self-service stores where customers use shopping carts.
Ved disse transportbånd bæres pladerne, der har en lastbærende, plan flade, ofte ved den ene af deres ender af en af de aksler, der forbinder to endeløse drivelementer, f.eks. kæder,med hinanden og har løberuller, ved hjælp af hvilke transportbåndet løber rundt på styreskinner. Da pladerne i forhold til drivelementeme er anbragt relativt højt, bliver de faste gelændere med almindelige håndlister i almindelighed anbragt ved siden af transportbåndet på en sådan måde, at der er et lille horisontalt spillerum mellem sokkelpladen for hvert gelænder og den tilsvarende side af transportbåndet.In these conveyor belts, the plates having a load bearing, flat surface are often carried at one of their ends by one of the shafts connecting two endless drive elements, e.g. chains, with one another and having rollers, by means of which the conveyor belt runs around on guide rails. Since the plates relative to the drive elements are positioned relatively high, the solid handrails with ordinary handrails are generally placed adjacent to the conveyor belt in such a way that there is a small horizontal clearance between the base plate for each handrail and the corresponding side of the conveyor belt.
Da transportbåndets sider ved de fleste indretninger bevæger sig i en lige linie, skulle det horisontale spil mellem transportbåndet og sokkelpladen for hvert gelænder i det mindste teoretisk set være uforandret ved denne anbringelse af gelænderne ved siden af transportbåndet. En sådan anbringelse har imidlertid visse ulemper. Således kan små genstande, som falder ned på transportbåndet, let glide ned mellem det kørende transportbånd og en af sokkelpladerne for gelænderet. Det synlige mellemrum kan da forlede brugeren til at forsøge at få fat på genstanden igen med fare for at få fingeren i klemme og dermed beskadige denne. Ved anlæg med større pladelængde forøges denne fare yderligere, da den mindste hældning af pladen med akslen, der bærer pladens ender, hvilken hældning kan være fremkaldt af tilfældige fabrikationsunøjagtigheder eller uens slid, kan bevirke en væsentlig sideforskydning af pladen ved dens anden ende. Det horisontale spillerum mellem transportbåndet og gelænderets sokkelplade kan således forøges unormalt, gøres mindre eller sågar helt forsvinde.Since, in most devices, the conveyor sides move in a straight line, the horizontal clearance between the conveyor belt and the base plate for each handrail should be at least theoretically unchanged in this arrangement of the handrails next to the conveyor belt. However, such an arrangement has certain disadvantages. Thus, small objects falling onto the conveyor belt can easily slide down between the moving conveyor belt and one of the railing plates for the railing. The visible gap can then lead the user to try to grab the object again with the danger of pinching his finger and thus damaging it. For larger plate length systems, this danger is further increased, as the smallest inclination of the plate with the shaft bearing the ends of the plate, which may be caused by accidental fabrication or uneven wear, can cause a significant lateral displacement of the plate at its other end. Thus, the horizontal clearance between the conveyor belt and the railing base plate can be increased abnormally, reduced or even completely disappeared.
Et forsøg på at indskrænke de ovenfor nævnte risici består i at anbringe de faste gelændere over transportbåndet, hvorved i dette tilfælde det nødvendige spillerum mellem den lastbærende flade af pladerne og underkanten af gelænderets sokkelplade bliver lodret.An attempt to mitigate the above-mentioned risks consists in placing the fixed handrails over the conveyor belt, in which case the necessary clearance between the load-bearing surface of the plates and the lower edge of the railing base plate becomes vertical.
En sådan løsning har ganske vist i forhold til den forrige betydelige fordele i tilfælde af en udelukkende horisontal nyttestrækning for transportbåndet. Den er dog vanskelig anvendelig ved transportbånd, der udviser en hældende og ved en kurve med et 3Such a solution, admittedly, has significant advantages over the previous case in the case of a purely horizontal utility line for the conveyor belt. However, it is difficult to use with conveyor belts exhibiting a slope and a curve with a 3

vandret plan forbundet nyttestrækning, da det lodrette spillerum ved kurvedele af vejstrækningen varierer i afhængighed af kurveradius og pladelængde. Det for de lige dele af vejstrækningen beregnede normale spillerum kan også i de konvekse kurver forøges væsentligt ved plademidten. Som i den foran nævnte løsning består der altså også her en vis fare for brugeren.horizontal plane associated utility stretching, as the vertical clearance at curve sections of the stretch of road varies depending on curve radius and plate length. The normal clearance for the equal parts of the stretch of road can also be significantly increased in the convex curves at the plate center. As in the solution mentioned above, there is also a certain danger here for the user.
Med opfindelsen tilsigtes der tilvejebragt et pladetransport-bånd, der gør anbringelsen af gelænderne over disse mulig, hvor der, under bibeholdelse af tilladelige værdier, såvel for de lige dele som for vejstrækningens kurveformede dele kan opnås lodrette spillerum af tilnærmelsesvis lige stor størrelse.The invention is intended to provide a plate conveyor belt which makes it possible to place the handrails over these, where, while maintaining permissible values, vertical space of approximately equal size can be obtained for both the straight and curved parts of the road section.
Dette opnås ifølge opfindelsen ved, at hver plade i sit bevægelsesplan og symmetrisk i forhold til sit midterplan har en geometrisk konveks, lastbærende flade, hvis tværsnit følger en cirkelbueformet kurve, hvis radius er større end radius for den af transportbåndet gennemløbne kurve. Spillerummet vil ganske vist her have forskellige værdier ved pladekanten og ved plademidten på de lige strækninger, men ved kurvestrækninger vil forskellene ikke være så store, som ved de kendte konstruktioner.This is achieved according to the invention in that each plate in its plane of motion and symmetrical with respect to its center plane has a geometrically convex, load-bearing surface, whose cross section follows a circular arcuate curve whose radius is greater than the radius of the curve passed by the conveyor belt. The game room will have different values here at the plate edge and at the plate center on the straight lines, but for curve stretches the differences will not be as great as with the known constructions.
Opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor der vises to udførelsesformer for opfindelsen, og hvor fig. 1 skematisk viser en af pladerne i et almindeligt pladetransportbånd, fig. 2 skematisk en af pladerne i en første udførelsesform for et pladetransportbånd ifølge opfindelsen på en kurvedel af vej strækningen, fig. 3 skematisk pladen i fig. 2 på en lige del af vejstrækningen, fig. 4 skematisk en plade i en anden udførelsesform for pladetransportbåndet ifølge opfindelsen, og fig. 5 og 6 en del af pladetransportbåndet ifølge opfindelsen i længdesnit på den lige del og på en kurvedel af vejstrækningen.The invention will be explained in more detail below with reference to the drawing, in which two embodiments of the invention are shown, and in which fig. 1 schematically shows one of the plates in a conventional plate conveyor belt; FIG. 2 schematically shows one of the plates in a first embodiment of a plate conveyor belt according to the invention on a curve part of the road section; FIG. 3 schematically shows the plate of FIG. 2 on an equal part of the road section; FIG. 4 schematically shows a plate in another embodiment of the plate conveyor belt according to the invention, and FIG. 5 and 6 show a portion of the plate conveyor belt according to the invention in longitudinal section on the straight portion and on a curve part of the road section.
På den skematiske afbildning i fig. 1 er en af pladetransportbåndets plader betegnet med 1, der alt efter indretningens art bevæger sig i en af de på tegningen angivne pilretninger. Pladen 1 har på sin øverste del en lastbærende flade 1.1, der er placeret i afstanden d fra en lige linie, som i tilfælde af en lige vejstrækning for transportbåndet svarer til underkanten 2.1 af sok- 144330 4 kelpladen for et fast gelænder. Denne underkant 2.1 af sokkelpladen er i tilfælde af et transportbånd, der gennemløber en vejstrækning med konveks kurve, vist ved hjælp af en stiplet buet linie med radius R. Da i praksis den på tegningen med hensigt forstørrede afstand d i sammenligning med pladens længde og med radius for den af transportbåndet gennemløbende konvekse kurve er ringe, kan denne radius såvel i fig. 1 som i de andre figurer betragtes som identisk med radius R for underkanten 2.1 af gelænderets sokkelplade.In the schematic diagram of FIG. 1 is one of the sheet conveyor belt plates designated 1, which, depending on the nature of the device, moves in one of the arrow directions indicated in the drawing. The plate 1 has on its upper part a load-bearing surface 1.1 which is located at the distance d from a straight line, which in the case of a straight stretch of road for the conveyor belt corresponds to the lower edge 2.1 of the socket plate for a fixed handrail. This lower edge 2.1 of the pedestal plate is shown in the case of a conveyor belt that traverses a road with convex curve, by means of a dashed curved line with radius R. Then in practice the distance in the drawing with intentionally enlarged in comparison with the length of the plate and with radius for the convex curve passing through the conveyor belt is low, this radius as well in FIG. 1, which in the other figures is considered identical to the radius R of the lower edge 2.1 of the railing base plate.
Fig. 1 viser ved en kurvedel af en gennemløben vejstrækning, at afstanden d i området ved pladens ender reduceres til dl = d-h, hvor h er den buehøjde, som dannes på kurven med radius R. på korden a, der svarer til længden af pladen 1. Såfremt pladen 1 er således styret, at afstanden d i området ved pladens ender bibeholdes ved passage af kurvedelen, viser fig.l endvidere, at der 1 så fald fremkommer en større afstand d2 = d+h i området ved pladens midte, hvor denne afstand ved lige vejstrækninger vil forekomme på hele længden af pladen 1. Såfremt den lastbærende flade 1.1 på pladen 1 havde et cirkelbueformet konvekst tværsnit, som fulgte en radius svarende til radius R, fremgår det endelig også af fig. 1, at afstanden d ganske vist ville være konstant ved en kurveformet vejstrækning, men at afstanden ved lige vejstrækning imidlertid ville være d2 ved pladens ender.FIG. 1 shows, by a curve part of a continuous stretch of road, that the distance d in the region at the ends of the plate is reduced to d1 = dh, where h is the arc height which is formed on the curve of radius R. on the chord a corresponding to the length of the plate 1. If the plate 1 is so controlled that the distance di the area at the ends of the plate is maintained as the passage of the curve part shows, Fig. 1 also shows that 1 then a greater distance d2 = d + h is obtained in the area at the center of the plate, where this distance at straight road sections will occur on the entire length of the plate 1. If the load-bearing surface 1.1 of the plate 1 had a circular arcuate convex cross-section which followed a radius corresponding to radius R, it is finally also apparent from fig. 1, that the distance d would be constant at a curvilinear stretch, but that the distance at straight stretch would be d2 at the ends of the plate.
På de skematiske figurer 2 og 3 har den øverste del af pladen 1 i sit løbeplan og symmetrisk med sin midterakse en lastbærende flade 1.2 med et tværsnit, der er cirkelbueformet konveks med en radius RI, som er større end radius R for den af transportbåndet gennemløbne kurve. Idet der gås ud fra en passende radius RI, er det på denne måde muligt at reducere forskellen mellem minimalværdien dl og maksimalværdien d2 i væsentlig grad. Fig.In the schematic figures 2 and 3, the upper part of the plate 1 in its running plane and symmetrically with its center axis has a load-bearing surface 1.2 having a cross-sectional convex convex having a radius R1 greater than the radius R of the conveyor belt curve. Assuming an appropriate radius R1, it is thus possible to substantially reduce the difference between the minimum value d1 and the maximum value d2. FIG.
2 og 3 viser endvidere, at højdeforskellen mellem enderne og midten af den lastbærende flade 1.2 udgør det halve af højdeforskellen h, når denne flades tværsnit er cirkelbueformet konveks med en radius R, dvs. en radius, som svarer til den af transporgbån-det gennemløbne kurve. Såfremt denne afstand antages som minimalafstand, så befinder denne sig ved gennemløb af en kurveformet del af vejstrækningen i området ved enderne, og en maksimalafstand D = d + j på midten af pladen 1 (fig. 2). Ved gennemløb af en lige vejstrækning befinder minimalafstanden d sig derimod i midten og maksimalafstanden D i området ved enderne af pladen (fig.2 and 3 further show that the height difference between the ends and the center of the load-bearing surface 1.2 constitutes half of the height difference h when the cross-section of this surface is circularly convex with a radius R, ie. a radius corresponding to the curve traversed by the transporgbahn. If this distance is assumed to be a minimum distance, it is located at the end of the curve by a curved part of the road section and a maximum distance D = d + j at the center of the plate 1 (Fig. 2). On the other hand, when traversing a straight stretch of road, the minimum distance d is in the center and the maximum distance D is in the area at the ends of the plate (fig.
144330 5 3). På denne måde er det muligt at opnå maksimale og minimale vertikale spillerum af samme størrelse såvel ved lige som ved kurveformede vejstrækninger mellem pladerne 1 og underkanten 2.1 af sokkelpladerne.3). In this way, it is possible to obtain maximum and minimum vertical clearance of the same size, both on straight and curved stretches of road between the plates 1 and the lower edge 2.1 of the plinths.
Ud fra formlen h = R - V? - fremgår det, at ..2 2 4 _ 4h + a R 8hFrom the formula h = R - V? - it appears that ..2 2 4 _ 4h + a R 8h
Radius RI, der er større end R, og som svarer til den halve buelængde bestemmes som følger: Δ 2 2 _ 2n + ar 4h * 2 2 2 2The radius RI greater than R and corresponding to half the arc length is determined as follows: Δ 2 2 _ 2n + ar 4h * 2 2 2 2
Heraf fremkommer forholdet = 4h n-v- -a---^* A_, R1 8h 2h2 + a2 4h2 + 2a2 2 hvilket viser, at jo mere h nærmer sig nul, som dette vil være tilfældet for de fleste indretninger, hvor buehøjden h er forholdsvis ringe, desto mere nærmer forholdet mellem de to radier _R_ 1 RI 2'Hence the ratio = 4h nv- -a --- ^ * A_, R1 8h 2h2 + a2 4h2 + 2a2 2 which shows that the more h approaches zero, as will be the case for most devices where the arc height h is relatively poor, the closer the ratio of the two radii approaches _R_ 1 RI 2 '
Det ligger inden for opfindelsens ramme at forsyne pladerne med en geometrisk konveks lastbærende flade, hvis tværsnit nok tilnærmelsesvis svarer til en cirkelbueformet kurve, hvis radius er større end radius for den af transportbåndet gennemløbne kurve, men som ikke ubetinget er en cirkelbueformet konveks kurve.It is within the scope of the invention to provide the plates with a geometric convex load-bearing surface, whose cross-section is roughly similar to a circular arcuate curve whose radius is greater than the radius of the conveyor belt passed but not necessarily a circular arcuate convex curve.
I den skematiske fig. 4 er den lastbærende flade 1.3 af pladen 1 en af tre planer bestående polygonal konveks flade, der er dannet svarende til en kurveradius R2, der er større end radius R for den af transportbåndet gennemløbne kurve. De ved polygonformen fremkommende kanter kan være afrundede. Den lastbærende flade kan også have et tværsnit med en plan midterdel og cirkelbueformede ender eller omvendt.In the schematic fig. 4, the load carrying surface 1.3 of the plate 1 is one of three planes consisting of a polygonal convex surface formed corresponding to a curve radius R2 which is larger than the radius R of the curve passed through the conveyor belt. The edges of the polygon shape may be rounded. The load bearing surface may also have a cross section with a flat center portion and circular arcuate ends or vice versa.
Fig. 5 og 6 viser i længdesnit en del af et pladetransportbånd med efter hinanden anbragte plader 3, der ved enderne på tværs af løberetningen med ikke viste midler er forbundet med et af leddene 4.1 og 4.2 af en drivkæde 4. Hver af drivkæderne 4 er forsynet med løberuller 5, ved hjælp af hvilke de bevæger sig ad en lige (fig. 5) eller en konveks kurveformet (fig. 6) styreskinne 6. Med 7 angives sokkelpladen af et fast gelænder, der bærer kendte håndlister. Underkanten af denne sokkelplade er med et vist lodret spillerum anbragt over den lastbærende flade 3.1 på pladerne 3.FIG. 5 and 6 show, in longitudinal section, a portion of a plate conveyor belt with successively arranged plates 3 connected at one end to the transverse direction by means not shown by one of the links 4.1 and 4.2 of a drive chain 4. Each of the drive chains 4 is provided with running rollers 5, by means of which they move along a straight (fig. 5) or a convex curved (fig. 6) guide rail 6. By 7, the base plate is indicated by a fixed handrail carrying known handrails. The lower edge of this base plate is provided with a certain vertical clearance over the load-bearing surface 3.1 on the plates 3.
