Opfindelsen angâr en styrebjælke til transport0rer af den i krav 11 s indledning angivne art.The invention relates to a guide beam for conveyors of the kind specified in the preamble of claim 11.

Sâdanne styrebjælker kendes f.eks. fra GB-PS nr. 1.131.332. I dette skrift er det ikke oplyst, hvorledes de formstofstrim-5 1er, der er anbragt pâ bæreflangerne, er forhindret i at kom-me 10s af bæreflangerne, hvad der dels kan ske pâ grund af de formændringspâvirkninger, soin strimlerne udsættes for under normal drift, dels pâ grund af gods, der f0res pâ tværs hen over transport0ren pâ en sâdan mâde, at der sker en util-10 sigtet sideværts pâvirkning af strimlerne, hvorved disse kan skubbes af. Desuden kan strimlerne let falde af pâ de ste-der, hvor transport0ren er b0jet i sideretningen.Such guide beams are known e.g. from GB-PS No. 1,131,332. In this document, it is not disclosed how the plastic strips placed on the support flanges are prevented from entering 10s of the support flanges, which can partly be due to the deformation effects to which the strips are exposed during normal operation. , partly because of goods being transported across the conveyor in such a way that there is an unintended lateral influence of the strips, thereby allowing them to be pushed off. Furthermore, the strips can easily fall off at the points where the conveyor is bent in the lateral direction.

Det kan selvsagt tænkes, at formstofstrimlerne er fastgjort ved klæbning, men dette ville medf0re ulemper bâde ved pâ-15 sætningen og ved udskiftningen af éventuelle slidte strimler - fraset den kendsgerning, at fastklæbning af formstofdele til métal normalt indebærer betydelige problemer med hensyn til holdbarhed og modstandsdygtighed imod vand, olie m.v..Of course, it is conceivable that the plastic strips are attached by adhesive, but this would cause drawbacks both in the application and in the replacement of any worn strips - with the exception that the adhesion of plastic parts to metal usually poses considerable problems in durability and water resistance, oil, etc.

Styrebjælken if0lge opfindelsen er ejendommelig ved den i 20 krav 11 s kendetegnende del angivne udformning. Herved op-nâs, at strimlerne - ogsâ i éventuelle kurver - fastholdes mekanisk formsluttende pâ bæreflangerne, hvad der imidlertid ikke er til hinder for, at de let kan udskiftes ved blot at âbne strimlerne, sâledes at indgrebsdelene pâ strimlerne og 25 bæreflangerne frig0res fra hinanden.The guide beam according to the invention is peculiar to the design according to the characterizing part of claim 20. Hereby it is achieved that the strips - also in optional curves - are kept mechanically molded on the support flanges, which, however, does not prevent them from being easily replaced by simply opening the strips, so that the engagement parts of the strips and the supporting flanges are released from each other .

Ved den i krav 2 angivne udf0relsesform undgâs svækkelse af bæreflangerne, idet éventuelle fordybninger i disse selvsagt ville forringe deres mekaniske styrke. 'In the embodiment set out in claim 2, weakening of the support flanges is avoided, since any recesses in these would obviously impair their mechanical strength. '

Opfindelsen vil blive nærmere forklaret i det f01gende under 30 henvisning til tegningen, der viser et snit gennem en bjælke 1, som har ensartede 0vre og nedre dele. Bjælken er forsynet med flanger 2, som strækker sig fra en kropdel 3 indad mod glide- - - 2The invention will be explained in more detail below with reference to the drawing, which shows a section through a beam 1 having uniform upper and lower parts. The beam is provided with flanges 2 which extend from a body part 3 inwards towards the slide - - - 2

ne 4 er fastgjort til et endel0st trækkabel 6 . Glideorganerne 4 er f-orsynet med fxemspring 7 pâ begge sider. Disse frem-sprüng er indrettet til at gribe ind i et drivtandhjul eller lignende.ne 4 is attached to an endless traction cable 6. The sliding members 4 are provided with projections 7 on both sides. These protrusions are arranged to engage a drive gear or the like.

5 If01ge opfindelsen hviler glidepladerne 5, som vist pâ tegnin-gen, i den 0vre stilling pâ en formstofstrimmel 8. Denne form-stofstriimnel kan fremstilles i meget lange længder, og den skubbes ind pâ flangen 2, hvorved enhver samling af strimmelen kan undgâs. For at sikre, at striinmelen holdes sikkert pâ plads, 10 er den forsynet med en fordybning 9, som samvirker med et til-svarende fremspring pâ flangen.5 According to the invention, the sliding plates 5, as shown in the drawing, rest in the upper position on a plastic strip 8. This plastic strip can be made for very long lengths and it is pushed into the flange 2, thereby avoiding any assembly of the strip. To ensure that the streamer is securely held in place, it is provided with a recess 9 which cooperates with a corresponding projection on the flange.

Nâr glideorganerne gâr tilbage, som vist pâ den nedre del af tegningen, vil de hænge pâ den indvendige side af bjælken mod formstofstrimmelen. Da formstofstrimmelen er st0ddæmpende , vil 15 enhver raslen være undgâet.When the sliding members return, as shown in the lower part of the drawing, they will hang on the inner side of the beam against the plastic strip. Since the plastic strip is shock absorbing, any rattle will be avoided.

¥âr sporet skal bue mod en af siderne, vil glideorganerne 4 presse mod kanten af flangen 2. Da ogsâ denne kant er forsynet med friktionsreducerende formstofmaterialef vil friktionen ogsâ i kurverne blive sâ lille, at der i mange tilfælde ikke er 20 behov for at anvende afb0jningshjul.When the groove is to bend to one of the sides, the sliding means 4 will press against the edge of the flange 2. Since this edge is also provided with friction reducing plastic material, the friction will also be so small in the curves that in many cases there is no need to use afb0jningshjul.

Med den foreliggende opfindelse opnâs en meget pâlidelig trans-port0r med et meget lavt lydniveau, og ved hvilken der ikke er risiko for, at glidepladerne skal hænge fast.The present invention provides a very reliable conveyor with a very low sound level and at which there is no risk of the sliding plates being stuck.

Monteringen af formstofstrimlerne er let udf0rt pâ grund af 25 snaplâsen. De er desuden fastlâst i stilling ogsâ af glideorganerne pâ grund af disses udformning.The mounting of the plastic strips is easily accomplished due to the 25 snap lock. In addition, they are fixed in position also by the sliding members due to their design.

Claims
