Description
15 20 25 30 35 18008193-8 _Fig. 1 från sidan visar en såganordning enligt uppfinningen och :Fig. 2 visar densamma uppifrån. 15 20 25 30 35 18008193-8 _Fig. 1 shows from the side a sawing device according to the invention and: FIG. 2 shows the same from above.
Den visade sågmaskinen tjänar till att med hjälp av sågblad V5, vilka är anordnade med inbördes axiella avstånd på en gemensam axel 4, producera lamellerat sâggods och utnyttja likaxligt till sågbladen anordnade spånverktyg 6, vilka för- vandlar de eljest kvarblivande, oregelbundna arbetsstycke- sidorna till för cellulosaframställning lämpad flis med med ytan parallell fiberriktning.The sawing machine shown serves to produce, with the aid of saw blades V5, which are arranged with mutual axial distances on a common axis 4, lamellar sawdust and to use chip tools 6 arranged on the same axis as the saw blades, which transform the otherwise remaining, irregular workpiece sides into chips suitable for cellulose production with a fiber direction parallel to the surface.
I detalj har sågmaskinen följande konstruktion: I-en maskinkropp 1 är inbyggda flera undre matarvalsar 2, vilka är lokalt fast anordnade, och övre, vertikalt rörliga matarvalsar 3. De undre matarvalsarnas 2 mantelytor bildar ett gemensamt transportplan 12 för bearbetade arbetsstycken W, av vilka ett i sitt före införandet i sâgmaskinen visade ändavsnitt i fig. 1 har förtydligats med en skraffering. Étt sådant arbetsstycke antyds i fig. 2 med streckade linjer.In detail, the sawing machine has the following construction: In a machine body 1 several lower feed rollers 2 are built in, which are locally fixedly arranged, and upper, vertically movable feed rollers 3. The outer surfaces of the lower feed rollers 2 form a common transport plane 12 for machined workpieces W, of which an end section shown in Fig. 1 in its pre-insertion in the sawing machine has been clarified with a hatching. One such workpiece is indicated in Fig. 2 by broken lines.
I maskinkroppens 1 centrum befinner sig en verktygsaxel 4, på vilken såväl cirkelsågblad 5 som spånverktyg 6 är anord- nade. Spånverktygen 6 bildar verktygssatsens högra och vänstra avslutning. Arbetsstyckena W förflyttas i den vid 7 antydda matningsriktningen genom maskinen, varvid verktygens rota- tionsriktning 8 motsvarar medmatningsbearbetningsprincipen.In the center of the machine body 1 there is a tool shaft 4, on which both circular saw blades 5 and chip tools 6 are arranged. The chip tools 6 form the right and left ends of the tool set. The workpieces W are moved in the direction of feed indicated by 7 through the machine, the direction of rotation 8 of the tools corresponding to the feed-in machining principle.
Denna medmatning betyder, att sågbladens 5 och spånverk- 'tygens 6 axel A är anordnad ovanför arbetsstyckenas trans- portplan 12 och att löpriktningen 8 för de snittstället 11 lâmnande sågbladen i dessas under axeln liggande avsnitt överensstämmer med arbetsstyckets W matningsriktning 7.This entrainment means that the axis A of the saw blades 5 and the chip tools 6 is arranged above the transport plane 12 of the workpieces and that the running direction 8 of the saw blades leaving the cutting point 11 in their sections below the shaft corresponds to the feed direction 7 of the workpiece W.
För att på fullgott sätt uppfånga flisningskrafterna, är direkt före verktygssatsen 4¿L6 anordnad en mottrycksanord- ning i form av en roterande eller fast mottrycksbalk 9. -v _- -»-- -_.__s ... . 10 15 8008193-8 Denna mottrycksanordning 9 sträcker sig parallellt med axelns 4 rotationsaxel A över maskinkroppens 1 hela bredd och be- finner sig i omedelbar närhet av snittlinjen 10 mellan rotationscirkeln 13 för spânverktygens 6 samtliga skärorgan 14 och arbetsstyckenas transportplan 12. Genom detta arrange- mang uppkommer den fördelen, att mottrycksbalken 9 kan verka väsentligen mot skärkrafterna.In order to fully absorb the chipping forces, a counter-pressure device in the form of a rotating or fixed counter-pressure beam 9. -v _- - »- -_.__ s ... is arranged directly before the tool set 4¿L6. 8008 8008193-8 This counterpressure device 9 extends parallel to the axis of rotation A of the shaft 4 over the entire width of the machine body 1 and is located in the immediate vicinity of the section line 10 between the rotation circle 13 of all cutting tools 6 of the chipping tools 6 and the transport plane 12. The advantage arises that the counterpressure beam 9 can act substantially against the shear forces.
I det visade utföringsexemplet uppvisar spån- eller flis- ningsverktygen 6 ett flertal växentligen radiella enskilda skärorgan 14, som inbördes har lika ingreppsdistans 15, vilken motsvarar den eftersträvade flislängden, som överens- stämmer med den parallellt med den uppstående flisens yta riktade träfiberlängden. Härur uppkommer den fördelen, att flisen i efterföljande bearbetnings- och upparbetningsförlopp på grund av den gynnsamma fiberlängden av 1-5 cm kan vidare- transporteras utan väsentlig andel av icke bearbetbart av- fall. Denna flis kan lätt avledas, så att den förblir skild från det av cirkelsågbladen 5 alstrade sågspånet.In the exemplary embodiment shown, the chip or chipping tools 6 have a plurality of substantially radial individual cutting members 14, which mutually have an equal engaging distance 15, which corresponds to the desired chip length, which corresponds to the wood fiber length directed parallel to the surface of the rising chip. This has the advantage that the chips in subsequent processing and reprocessing processes due to the favorable fiber length of 1-5 cm can be transported without a significant proportion of non-processable waste. This chip can be easily diverted so that it remains separate from the sawdust generated by the circular saw blades 5.
