5 Opfindelsen angår kardankædeled til transportører af den i krav l's indledning angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to cardan chain links to conveyors of the kind set forth in claim 1.

Sådanne transportører anvendes i meget stor udstrækning f.eks. i produktionsindustrien til transport af 10 varer, d.v.s. både råvarer, halvfabrikata og færdigvarer .Such conveyors are widely used, e.g. in the manufacturing industry for the transport of 10 goods, i.e. raw materials, semi-finished products and finished goods.

Kædeleddene i sådanne transportører er almindeligvis fremstillet ved støbning af kunststof, f.eks. ved 15 sprøjtestøbning af egnede plastmaterialer såsom Acetal, Acetal med tilsætning af selvsmørende additiver,The chain links in such conveyors are generally made by molding plastic, e.g. by injection molding of suitable plastic materials such as Acetal, Acetal with the addition of self-lubricating additives,

Nylon eller lignende plastmaterialer. Kædeleddene kan dog også være fremstillet af metal, f.eks. stål, eller være sammensat af plast og stål.Nylon or similar plastic materials. However, the chain links may also be made of metal, e.g. steel, or be made of plastic and steel.

De kendte transportører af denne art er almindeligvis udformet af kædeled, der er lukket ovenpå, d.v.s., at i hvert fald det stykke af benene, som er beliggende nærmest leddelen med kardanleddet, har en topplade, 25 almindeligvis udformet ud-i-et med benene og leddelen. Herved fremkommer der et hulrum under toppladen, som er vanskeligt at rengøre effektivt. En effektiv rengøring af en transportør er imidlertid et krav, hvis transportøren anvendes i en levnedesmiddel- el-30 ler nydelsesmiddel-virksomhed, hvor der er meget strenge krav til hygiejnen. Dette er især vigtigt, hvis transportøren anvendes til transport af råvarer eller uemballerede færdigvarer, hvilket f.eks. er tilfældet på slagterier, mejerier, konservesvirksom-The known conveyors of this kind are generally formed of chain links which are closed on top, that is, at least the piece of the legs which is closest to the articulated joint with the cardan joint has a top plate, usually formed in one with the legs. and the joint. This creates a cavity beneath the top plate which is difficult to clean effectively. However, efficient cleaning of a conveyor is a requirement if the conveyor is used in a food or delicatessen business where there are very strict hygiene requirements. This is especially important if the carrier is used for the transport of raw materials or unpackaged finished goods, which e.g. is the case at slaughterhouses, dairies, canning companies

2 heder, dybfrostvirksomheder, m.v.2 heaths, deep-frozen establishments, etc.

Fra svensk fremlæggelsesskrift nr. 437.649 kendes et kardanled af den i krav l's indledning angivne art, 5 men hvor den krumme leddel ikke har nogen fast topplade. Kædeleddet er indrettet til at påmonteres en udskiftelig topplade, der klemmes fast indvendigt mellem benene. Presset på benene fra overdelen udlignes af en trækbjælke umiddelbart ved den krumme led-10 del, hvilken trækbjælke også kan være indrettet til at fastholde toppladen. Et sådant kædeled kan kun rengøres tilstrækkeligt ved at aftage toppladen, hvorfor sådanne kardankæder af denne type ikke anvendes som transportører i virksomheder, hvor der stil-15 les strenge krav til hygiejnen.From Swedish Patent Specification No. 437,649, a cardan joint of the kind specified in the preamble of claim 1 is known, but where the curved joint portion has no fixed top plate. The chain link is arranged to be mounted on a replaceable top plate which is clamped internally between the legs. The pressure on the legs from the top is offset by a drawbar immediately at the curved link portion, which drawbar can also be arranged to hold the top plate. Such a chain link can only be adequately cleaned by removing the top plate, which is why such chain chains of this type are not used as conveyors in companies where strict hygiene requirements are imposed.

Formålet med opfindelsen er at angive et kardankæde-led til transportører udformet således, at en totalrengøring af kædeleddene kan udføres, uden at dette 20 på nogen måde forringer transportørens funktion.The object of the invention is to provide a chain link joint for conveyors designed so that a total cleaning of the chain links can be carried out without in any way impairing the function of the conveyor.

Dette opnås ved at udforme kædeleddet ifølge opfindelsen som angivet i krav l's kendetegnende del. Herved fås mulighed for direkte at gennemskylle eller 25 gennemspule kædeleddene fra oversiden, idet der ingen delvis lukkede områder findes, fordi kædeleddene er helt uden topplade. Hvis man blot fjerner toppladen på de kendte kædeled, fås en kraftig forøgelse af friktionen i kardanleddet, fordi drivmotorens træk i 30 kæden vil søge at presse benene sammen, hvorved der sker klemning, både af kardanleddet inde i leddets krumme del og af benenes tryk udvendigt på den krumme del.This is achieved by forming the chain link according to the invention as set forth in the characterizing part of claim 1. This gives the opportunity to directly flush or flush the chain links from the upper side, since no partially closed areas exist because the chain links are completely without top plate. Simply removing the top plate of the known chain links results in a sharp increase in friction in the joint, because the drive of the drive in the chain will try to compress the legs, thereby squeezing, both of the joint in the curved part of the joint and the exterior of the legs. on the curved part.

DK 152689 BDK 152689 B

Med opfindelsen ifølge krav 1 får man således et kar-dankædeled, der er helt åben for rengøring, uden at klemning kan opstå, så kædeleddene bevarer deres fulde drejelighed og kan passere kurver og vendehjul med 5 lille radius helt uden problemer. Totalt kan man også udforme kardanleddet med spinklere dimensioner, så kæden yderligere bliver billigere og lettere.Thus, with the invention according to claim 1, a cart chain link which is fully open for cleaning can be obtained without squeezing, so that the chain links maintain their full rotatability and can pass curves and turning wheels with a small radius without any problems. In total, the cardan joint can also be designed with flatter dimensions, so that the chain is further cheaper and lighter.

Ved at udforme kardankædeleddet ifølge opfindelsen 10 får man en solid forbindelse mellem benene, så forbindelsen både kan optage tryk- og trækspændinger.By forming the cardan chain link according to the invention 10, a solid connection is obtained between the legs, so that the connection can absorb both compressive and tensile stresses.

Desuden muliggøres rengøring med kraftige midler, f.eks. højtryksspuling med vand eller damp, og man får maksimal styrke i tværgående retning for minimalt 15 materialeforbrug. Støttebjælken bør anbringes så langt fra den krumme del som muligt, uden at den kommer i vejen for det næste kardanled i kæden.In addition, cleaning with powerful means, e.g. high pressure flushing with water or steam, and you get maximum strength in transverse direction for a minimum of 15 material consumption. The support beam should be positioned as far from the curved part as possible without interfering with the next universal joint in the chain.

Ved at udforme kardankædeleddet ifølge opfindelsen 20 som angivet i krav 2's kendetegnende del, kan det nye kædeled fremstilles uden forøgede omkostninger, idet støttebjælken kan placeres i støbeformens åbningsplan, så støttebjælken fremstilles samtidig med og ud-i-et med selve kædeleddet.By designing the cardan chain link according to the invention 20 as defined in the characterizing part of claim 2, the new chain link can be manufactured at no increased cost, the support beam being placed in the opening plane of the mold so that the support beam is manufactured simultaneously with and out with the chain link itself.

For fuldstændigt at undgå, at snavs m.v. kan sætte sig fast på eller under støttebjælken, kan denne fortrinsvis være udformet som angivet i krav 3's kendetegnende del. En yderligere forenkling af ren-30 gøringsarbejdet opnås herved.To completely avoid dirt, etc. may be fixed to or below the support beam, it may preferably be configured as specified in the characterizing portion of claim 3. A further simplification of the cleaning work is thereby achieved.

Ved at udforme kardankædeleddet ifølge opfindelsen som angivet i krav 4's kendetegnende del, sikrer man sig at støttebjælken aldrig kommer i kontakt medBy designing the cardan chain link according to the invention as set forth in the characterizing part of claim 4, it is ensured that the support beam never comes into contact with the

4 det/de kædehjul eller medløberhjul, der trækker og fører kæden.4 the sprocket (s) or sprocket (s) that pull and guide the chain.

Opfindelsen forklares herefter nærmere under henvis-5 ning til tegningen, der viser en foretrukken udførelsesform for opfindelsen, idet fig. 1 viser kædeled ifølge opfindelsen i aksonometrisk afbildning set skråt oppefra, 10 og fig. 2 viser det samme kædeled som fig. 1, men set skråt nedefra.The invention is then further explained with reference to the drawing which shows a preferred embodiment of the invention, fig. 1 shows a chain link according to the invention in an axonometric view, obliquely from above, and FIG. 2 shows the same chain link as FIG. 1, but seen obliquely from below.

15 På tegningen angiver 1 et kædeled bestående af en krum del 4 med en transportflade 2 og to ben 5, hvis overside (fig. 1) også udgør en transportflade og derfor er udformet ud-i-et med og i samme niveau som transportfladen 2.In the drawing, 1 denotes a chain link consisting of a curved portion 4 with a conveying surface 2 and two legs 5, the upper side of which (Fig. 1) also constitutes a conveying surface and is therefore formed out-of-one with and at the same level as the conveying surface 2 .

20 I den krumme del 4 er der udformet et sædvanligt kar-danled omfattende en drejelig indsats 3, der kan drejes som vist ved den krumme dobbeltpil. Igennem indsatsens tværboring er der ført en aksel 6, der kobler 25 nabokardanled sammen, idet der i den krumme del 4 er udformet et langhul 7 i hver side, og idet der i hvert ben 5 er et hul til akselen 6.In the curved portion 4, a conventional carton member is formed comprising a pivoting insert 3 which can be rotated as shown by the curved double arrow. Through the transverse bore of the insert there is provided a shaft 6, which connects 25 adjacent cardinal joints, in the curved part 4 a long hole 7 is formed on each side, and in each leg 5 there is a hole for the shaft 6.

Sådanne kardanledskæder trækkes af et kædehjul, hvis 30 specielt formede tænder går i indgreb med kardankæ-dens underside, idet tænderne trykker på indsatsens 3 afrundede side, hvis transportørens bevægelsesretning skal være som vist ved pilen 9.Such universal joint chains are pulled by a sprocket whose 30 specially shaped teeth engage with the underside of the universal chain, the teeth pressing on the rounded side of the insert 3 if the direction of movement of the conveyor is to be as shown by arrow 9.

DK 152689 BDK 152689 B

Et langsgående træk i kæden vil søge at tvinge benene 5 mod hinanden med klemning af indsatsen 3 og den krumme dels 4 yderside til følge. Dette hindres af støttebjælken 8, der er støbt ud-i-et med benene 5 og 5 af samme materiale. Bjælken 8 er anbragt vinkelret på transportørens bevægelsesretning 9 og har en glat, afrundet overflade, f.eks. ved at være udformet cylindrisk med cirkulært tværsnit og med en diameter på 2-5 mm, fortrinsvis 3 mm.A longitudinal pull in the chain will seek to force the legs 5 towards each other with the clamping of the insert 3 and the outer surface of the curved part 4 as a result. This is prevented by the support beam 8, which is molded out-in-one with the legs 5 and 5 of the same material. The beam 8 is perpendicular to the direction of movement of the conveyor 9 and has a smooth, rounded surface, e.g. by being cylindrical in circular cross section and having a diameter of 2-5 mm, preferably 3 mm.

10 I øvrigt viser tegningen et eksempel på et kardankæ-deled ifølge opfindelsen i det væsentlige i naturlig størrelse.10 The drawing further shows an example of a cardan chain link according to the invention substantially in natural size.

15 Støttebjælken 8 er anbragt i så stor afstand som muligt fra den krumme del 4, som dette er muligt af hensyn til nabokædeleddet, hvilket vil sige, at den fortrinsvis er anbragt nærmere den aksel, der er anbragt i benene end den aksel, der er anbragt i ledde- 20 len. Støttebjælken 8 skal selvfølgelig anbringes således, at trækkædehjul og medløberhjul ikke kommer i kontakt med bjælken.The support beam 8 is spaced as far as possible from the curved portion 4 as this is possible for the sake of the neighbor chain link, i.e. it is preferably located closer to the shaft placed in the legs than the shaft which is placed in the joint. The support beam 8 must, of course, be arranged so that traction sprockets and idler wheels do not come into contact with the beam.
