Description
i 148137and 148137
Opfindelsen angår en kædetransportør af den i indledningen til krav 1 angivne art. Sådanne transportører, der er konstrueret til transport af flasker, dåser og lignende beholdere kendes f.eks. fra beskrivelsen til det 5 amerikanske patentskrift nr. 3 262 550. For at hindre at de kendte transportørers kædeled i brug løftes af sporet på bøjningens yderside på grund af trækkraften i kæden, er der dannet styreflader på kædeleddene under disses bæreflader, hvilke styreflader divergerer bort fra 10 bærefladen og samvirker i bøjningerne med tilsvarende styreflader i nærheden af sporet.The invention relates to a chain conveyor of the type specified in the preamble of claim 1. Such conveyors designed for transporting bottles, cans and similar containers are known e.g. from the description of U.S. Pat. No. 3,262,550. from the bearing surface and cooperates in the bends with corresponding guide surfaces near the track.
Sådanne mekaniske organer til at holde en transportkæde fladt på sporet i et sving medfører en række ulemper.Such mechanical means for keeping a conveyor chain flat on the track in a turn entails a number of disadvantages.
Faktum er, at foruden de uundgåelige styreorganer på spo-15 rets svingstrækninger, kræver de på den ene eller anden måde, at der tilvejebringes lateralt fremspringende eller hældende styreflader på alle kædeled. Især ved metalled medfører dette behov for en yderligere operation, hvilket gør leddene relativt dyre. Ydermere svækkes leddene be-20 tydeligt. Spor for kædetransportører af den nævnte art er nemlig standardiseret i høj grad, dvs. i praksis har den korteste afstand mellem de to skinner, der udgør sporet, en fast værdi, nemlig omkring 44 mm. Hængselforbin-delsen mellem kædens naboled tilvejebringes ved hjælp af 25 en hængselbolt, der omsluttes af to øjer, der er forbundet med ét led, og et øje på et nærliggende led, hvilket øje er beliggende midt mellem nævnte to øjer. For at kæden skal kunne bevæges gennem et sving, må hængselforbindelsen naturligvis tillade, at leddene drejer relativt i 30 transportplanet.The fact is that in addition to the unavoidable guide means on the pivotal trajectories of the track, they require in one way or another that laterally projecting or inclined guide surfaces be provided on all chain links. Especially with metal joints, this entails the need for further surgery, which makes the joints relatively expensive. Furthermore, the joints weaken significantly. Tracks for chain conveyors of the kind mentioned are in fact standardized to a great extent, ie. in practice, the shortest distance between the two rails that make up the track has a fixed value, namely about 44 mm. The hinge connection between the adjacent members of the chain is provided by means of a hinge bolt enclosed by two eyes connected by one joint and an eye on a nearby joint, which eye is located midway between said two eyes. In order for the chain to be able to move through a turn, the hinge connection must of course allow the joints to rotate relatively in the transport plane.
I de i beskrivelsen til det amerikanske patentskrift nr.In those in the specification of U.S. Pat.
3 262 550 beskrevne kædeled, er de laterale endeflader på hvert hængsels ydre øje udformet som styreflader, der divergerer nedad og bort fra bærefladen, således at hængs- 2 T48137 lets bunddel, dvs. den del af hængslet der ligger længst væk fra bæreflader, er bredest. For at hængslet skal kunne passere mellem sporets skinner i dettes lige strækninger, må den bredeste del af hængslet derfor ikke være 5 bredere end omkring 42 mm. Dette betyder imidlertid, at ved forbindelsespunktet, dvs. ved det punkt hvor hængselsforbindelsen overfører kraft til naboleddets bsreflade, er hængslet mindre end 42 mm bredt. I praksis medfører dette i sammenligning med kæder, der er konstrueret ude-10 lukkende til lige baner, og som derfor ikke kræver styreflader for at holde kæden fladt i sving, en svækkelse på omkring 20% med hensyn til den maksimalt tilladelige trækkraft i kæden.3 262 550, the lateral end faces of the outer eye of each hinge are formed as guide surfaces which diverge downwards and away from the support surface, so that the bottom part of the hinge, i.e. the part of the hinge that is furthest away from the bearing surfaces is widest. In order for the hinge to be able to pass between the rails of the track in its straight stretches, the widest part of the hinge must therefore not be 5 wider than about 42 mm. However, this means that at the connection point, i.e. at the point where the hinge connection transmits force to the bearing surface of the adjacent joint, the hinge is less than 42 mm wide. In practice, in comparison with chains which are designed exclusively for straight tracks and which therefore do not require guide surfaces to keep the chain flat in swing, this results in a weakening of about 20% with regard to the maximum permissible traction in the chain.
En anden ulempe ved mekaniske kædestyr af nævnte art, i 15 hvilke der i svingene på den ene eller anden måde er anbragt en styreflade på hvert kædeled under en tilsvarende styreflade på sporet, er, at forureninger,, som f.eks. hårde og ru partikler fra knuste flasker, lander på skinnerne og trænger ind mellem styrefladerne og beskadiger de på-20 gældende flader, især hvis disse er fremstillede af bløde, syntetiske plastmaterialer, der er udvalgt på grund af deres lave friktionsegenskaber.Another disadvantage of mechanical chain guides of the kind mentioned, in which in the turns a guide surface is arranged in one way or another on each chain link under a corresponding guide surface on the track, is that contaminants, such as e.g. hard and rough particles from broken bottles, land on the rails and penetrate between the guide surfaces and damage the applicable surfaces, especially if these are made of soft, synthetic plastic materials selected due to their low friction properties.
Fra det tyske fremlæggelsesskrift 1 556 183 er det kendt at anbringe magneter under en transportbane. Det primære 25 formål i dette skrift er at tilvejebringe et spredningsfelt til at fastholde genstande på transportørens kædeled. Magnetfeltet strækker sig over transportbanens fulde længde og medfører derfor en stor friktionsmodstand.It is known from German Offenlegungsschrift 1,556,183 to place magnets under a conveyor belt. The primary purpose of this document is to provide a spreading field for holding objects on the chain link of the conveyor. The magnetic field extends over the full length of the transport path and therefore causes a large frictional resistance.
Formålet med opfindelsen er at angive en kædetransportør, 30 som hindrer, at kædeleddene løftes i de udvendinge zoner i et spors sving. Teoretisk skulle kædeleddene i et fladt sving ikke blive løftet. Men i praksis har det vist sig, at blot en ubetydelig uregelmæssighed er tilstrækkelig 148137 3 til at løfte leddene i de ydre zoner i et fladt sving.The object of the invention is to provide a chain conveyor which prevents the chain links from being lifted in the turning zones in a turn of a track. Theoretically, the chain links in a flat turn should not be lifted. But in practice it has been found that merely an insignificant irregularity is sufficient to lift the joints in the outer zones in a flat turn.
Dette formål opnås ifølge opfindelsen ved, at kædetransportøren er udformet som angivet i den kendetegnende del af krav 1. Virkningen af det angivne anker i et par mag-5 neter er, at magnetfeltet på magneternes overflade bli ver meget kompakt og fladt, med andre ord koncentreret i et område, som kædetransportøren skal passere, når den bevæges gennem et sving. Eftersom næsten hele magnetfeltet herved anvendes til at frembringe den ønskede nedtræknings-10 kraft på kædeleddene, er et felt med lille magnetisk potentiale, som producerer et minimum af friktion, tilstrækkelig til opnåelse af dette. I tilfælde af akkumulering af snavs på sporet, løftes kæden over dette snavs, men er stadig påvirket af magnetfeltet, så at vipning eller af-15 sporing hindres. Efter passage af forureningerne trækkes kæden igen fast ned !på sporet.This object is achieved according to the invention in that the chain conveyor is designed as stated in the characterizing part of claim 1. The effect of the stated anchor in a pair of magnets is that the magnetic field on the surface of the magnets becomes very compact and flat, in other words concentrated in an area that the chain conveyor must pass when moving through a bend. Since almost the entire magnetic field is thereby used to produce the desired pull-down force on the chain links, a field with small magnetic potential which produces a minimum of friction is sufficient to achieve this. In case of accumulation of dirt on the track, the chain is lifted over this dirt, but is still affected by the magnetic field, so that tilting or derailment is prevented. After passing the contaminants, the chain is pulled down firmly on the track again.
Opfindelsen vil blive nærmere beskrevet i det følgende under henvisning til tegningen, hvor fig. 1 er et planbillede af en svingstrækning af transpor-20 tøren ifølge opfindelsen, fig. 2 er et tværsnit i større målestok langs pilene II-JI, og fig. 3 er et tværsnit analogt med fig. 2 og viser en anden udførelsesform af opfindelsen.The invention will be described in more detail in the following with reference to the drawing, in which fig. 1 is a plan view of a turning section of the conveyor according to the invention, fig. 2 is a cross-section on a larger scale along the arrows II-JI, and fig. 3 is a cross section analogous to FIG. 2 and shows another embodiment of the invention.
25 På tegningen er der vist en kædetransportør, der omfatter opstående sidevægge 1 og 2, mellem hvilke der er monteret et af skinner 3 og 4 dannet spor. På skinnerne hviler en ledkæde bestående af kædeled 5, idet hvert led på den ene side er forsynet med i indbyrdes afstand liggende hængsel-30 øjer 6 og på den anden side med et centralt placeret hæng- 148137 4 seløje 7. Hængseløjerne 6 og 7 omgiver hver en hængsel-bolt 8 - I den i fig. 1 og 2 viste udførelsesform, er skinnerne 3 og 4 i det mindste i svingstrækningerne forsynet med per-5 manente magneter 9 og 10, der kan være udformet som langstrakte permanente magneter, der hver strækker sig gennem hele svinget; alternativt kan der være anordnet en række korte magnetstykker både i det indvendige sving og det udvendige sving. Magneterne 9 og 10 er anbragt inde i skin-10 nerne 3 og 4, der er hule, og ved deres underside forbundet med en feltstrimmel 11, dvs. en strimmel af et materiale med en stor magnetisk permeabilitet, som f.eks. blødt jern, således at der sammen med kæden af det magnetiserbare materiale, der hviler på skinnerne 3 og 4, dan-15 nes et lukket kraftfelt som vist med stiplede linier.The drawing shows a chain conveyor comprising upright side walls 1 and 2, between which a track formed by rails 3 and 4 is mounted. On the rails rests a hinge chain consisting of chain hinge 5, each hinge being provided on one side with spaced hinge eyes 6 and on the other side with a centrally located hinge eye 7. The hinge eyes 6 and 7 surround each a hinge bolt 8 - In the one shown in fig. 1 and 2, the rails 3 and 4 are provided at least in the pivot lines with permanent magnets 9 and 10, which may be designed as elongate permanent magnets, each extending through the entire pivot; alternatively, a series of short magnetic pieces may be provided in both the inner bend and the outer bend. The magnets 9 and 10 are arranged inside the rails 3 and 4, which are hollow, and at their underside connected to a field strip 11, i.e. a strip of a material with a large magnetic permeability, such as e.g. soft iron, so that together with the chain of the magnetizable material resting on the rails 3 and 4, a closed force field is formed as shown by dashed lines.
Den vandrette styring af kæden foretages af hsngseløjer-ne 6 og 7, der ligger inde i skinnerne 3 og 4, og den lodrette "styring" af magneterne 9 og 10.The horizontal control of the chain is performed by the hinge eyes 6 and 7 located inside the rails 3 and 4, and the vertical "control" of the magnets 9 and 10.
For at reducere den modstand, som kæden skal overvinde ved 20 sin bevægelse over skinnerne, kan der på hver skinne være anbragt en plastliste 12. Gode resultater opnås med en polyethylen med stor molekylevægt, idet denne er et blødt og slidmodstandsdygtigt materiale.In order to reduce the resistance which the chain must overcome by its movement over the rails, a plastic strip 12 can be arranged on each rail. Good results are obtained with a high molecular weight polyethylene, as this is a soft and wear-resistant material.
I en foretrukken udførelsesform af opfindelsen, som vist i 25 fig. 3, er det magnetiske kædestyr for hver svingstrækning dannet af én eller flere sektioner af en enhed, der består af en feltstrimmel 11' med magneter både på over- og undersiden, nemlig magneterne 9 og 9' ved det indvendige sving og magneter 10 og 10' ved det udvendige sving. Her kan der 30 også dannes et lukket kraftfelt ved rigtigt valg af magneternes polaritet, dog i dette tilfælde ikke gennem feltstrimmelen 11', men derimod ved undersiden af returløbet R og ved toppen ved hjælp af kædens trækløb T.In a preferred embodiment of the invention, as shown in fig. 3, the magnetic chain guide for each swing section is formed by one or more sections of a unit consisting of a field strip 11 'with magnets on both the top and bottom, namely the magnets 9 and 9' at the inner swing and magnets 10 and 10. 'at the external turn. Here a closed force field can also be formed by the correct choice of the polarity of the magnets, but in this case not through the field strip 11 ', but instead at the underside of the return run R and at the top by means of the chain drive T.
