Abstract
Description
15 20 25 512, 40,3 2 Dessa syften uppnås genom ett sätt för framställning av takstolar och en anordning för användning vid det inledningsvis angivna sättet, genom de särdrag som anges i de bifogade patentlcaven. 512, 40.3 2 These objects are achieved by a method of manufacturing trusses and an apparatus for use in the method initially set forth, by the features set forth in the appended patents.
Enligt uppfinningen åstadkoms med enkla medel en anordning som kan användas vid dubbelkapning, företrädesvis av takstolselement, som väsentligt ökar noggrann- heten i kapningen av sådana takstolselement samt reducerar bearbetningstiden.According to the invention, a device is provided by simple means which can be used for double cutting, preferably of truss elements, which significantly increases the accuracy in the cutting of such truss elements and reduces the machining time.
Konstruktionen enligt uppfinningen möjliggör en mycket eñektiv operation som är lämpad för en hög grad av automatisering.The design according to the invention enables a very efficient operation that is suitable for a high degree of automation.
Uppfinningen beskrivs i det följande närmare med hjälp av ett på bifogade ritning visat utföringsexempel, där: fig. l är en perspektivvy av anordningen enligt uppfinningen, fig. 2 är en perspektivvy av en sågenhet enligt uppfinningen, där inmamings- och unnamingsmekanismer för ämnen/element har utelämnats, och fig. 3 är en perspektivvy som visar de i fig. 2 utelämnade mekanismema.The invention is described in more detail below with the aid of an exemplary embodiment shown in the accompanying drawing, in which: fi g. l is a perspective view of the device according to the invention, fi g. 2 is a perspective view of a saw unit according to the invention, in which feeding and removing mechanisms for blanks / elements have been omitted, and fi g. 3 is a perspective view showing the i fi g. 2 omitted the mechanisms.
Fig. 1 visar en utföringsform med två sågenheter 1 och 2, i form avi och för sig kända sågenheter, anordnade bredvid varandra och förbundna medelst en räls 13, varvid en av sågarna 2 är stationär medan den andra sågen 1 är rörlig i sidled relativt sågen 1 och således möjliggör enkel inställning av den önskade kapningslängden hos ett takstolselement.Fig. 1 shows an embodiment with two saw units 1 and 2, in the form of saw units known per se, arranged next to each other and connected by means of a rail 13, one of the saws 2 being stationary while the other saw 1 is movable laterally relative to the saw 1 and thus enables easy adjustment of the desired cutting length of a truss element.
Sågenhetema l och 2 har ett vridbord 3 for inställning av kapningsvinkeln (ï9()°) med ett sågblad som kan tippas 45°. Vridbordet 3 kan vridas l80° med hjälp av ett verktyg (ej visat) som är anbringat i lämpliga hål i vridbordet för manuell eller mo- toriserad rotation/utställning av kapningsvinkeln. Ett övre skydd 4 med sugfunktion är anbringat ovanför vridbordet 3, varvid det övre skyddet 4 är höj- och sänkbart monterat på en låskropp 5, som via en arm 6 är monterad vid ett höm eller en kant 10 20 25 512 403 3 på sågen. På motsatta sidor av sågama 1 och 2 finns hållare 7 för fasthållning av elementämnet mot en skena 8 som är justerbart anordnad på arbetsbordet, och vida- re finns utmatningsmekanismer 9 i form av höj- och sänkbara rullufansportörer för automatisk utmaming av färdiga takstolar från arbetsbordet till ett område bakom sågama. Skenan 8, som är försedd med ett stopp 10 för anliggning mot elementet, och som samverkar med hållaren 7 för att låsa elementärnnet, kan ställas in med hjälp av en arm 11 för att uppnå korrekt centmmavstånd. För placering av elemen- tärnnena i längdrikmingen finns ett ställbart stopp 14 mitt emot skenan 8. Vidare avlägsnas ändkapstycken och liknande automatiskt med hjälp av en pneumatiskt dri- ven anordning 15, som ”borstar” arbetsbordet, företrädesvis vid sågenheten 1.The saw units 1 and 2 have a turntable 3 for setting the cutting angle (ï9 () °) with a saw blade that can be tilted 45 °. The turntable 3 can be turned 180 ° by means of a tool (not shown) which is mounted in suitable holes in the turntable for manual or motorized rotation / setting of the cutting angle. An upper cover 4 with suction function is arranged above the turntable 3, the upper cover 4 being height-adjustably mounted on a locking body 5, which is mounted via an arm 6 at a corner or an edge 10 of the saw. On opposite sides of the saws 1 and 2 there are holders 7 for holding the element blank against a rail 8 which is adjustably arranged on the work table, and furthermore there are discharge mechanisms 9 in the form of height-adjustable roller conveyors for automatic unloading of finished trusses from the work table to an area behind the sawmills. The rail 8, which is provided with a stop 10 for abutment against the element, and which cooperates with the holder 7 for locking the element rail, can be adjusted by means of an arm 11 to achieve the correct centimeter distance. To place the elements in the longitudinal groove, there is an adjustable stop 14 opposite the rail 8. Furthermore, end cap pieces and the like are removed automatically by means of a pneumatically driven device 15, which “brushes” the work table, preferably at the saw unit 1.
Anordningen manövreras med hjälp av ett styrdon 12, anordnat mellan sågenhetema 1 och 2, och bestående av en tvåhandsmanövrerad frigöringsanordning, som medelst PLS-styrdon (ej visat) styr arbetscykeln.The device is operated by means of a control device 12, arranged between the saw units 1 and 2, and consisting of a two-hand-operated release device, which controls the working cycle by means of PLC control devices (not shown).
Framställning av takstolselement eller andra material av trä, där båda ändarna på elementen måste kapas, utförs på följande sätt: Anordningen, som enligt fig. 1 omfattar två halvautomafiska maskiner, företrädesvis sågar av märket Gjerde, där sågbladet är beläget under bordsytan/vridbordet och vid kapning höjs upp genom denna, och där endast inmatning av elementänmena sker på manuell väg, ställs in med avseende på den önskade kapningslängden med hjälp av sågen 1 och i relation till elementets bredd med hjälp av armen 11. Elementämnena fixeras i längdled med hjälp av det inställbara stoppet och matas därefter in kontinu- erligt med hjälp av inmataren till korrekt läge. Den efterföljande arbetscykeln styrs automatiskt med hjälp av den tvåhandsmanövrerade frigöringsanordningen 12. Det elementämne som placerats mot stoppen 10 med hjälp av de pneumatiska hållarna 7, fixeras därefter med hjälp av låsmekanismema 5, samtidigt som de övre skydden 4 sänks ned över kapningszonema. Sågbladen föres upp genom en slits i arbetsbordet, kapar elementämnet och återvänder till utgångsläget. De övre skydden 4, låsmeka- || lll lH ' ll II lll ll lll l lll l lll lll ll llll 10 15 512 403 4 nismema 5 och hållarna 7 återvänder därefter, och elementämnet lyfts med hjälp av rulltransportörema 9 och tippas ut bakom sågenhetema. Slutligen avlägsnas änd- stycken och liknande med hjälp av anordningen 15, företrädesvis på sågenheten 1.The manufacture of truss elements or other materials of wood, where both ends of the elements must be cut, is carried out as follows: The device, which according to fi g. 1 comprises two semi-automatic fi machines, preferably saws of the Gjerde brand, where the saw blade is located below the table surface / turntable and when cut is raised through it, and where only the elements are entered manually, set with respect to the desired cutting length by means of the saw 1 and in relation to the width of the element by means of the arm 11. The element blanks are fi x longitudinally by means of the adjustable stop and are then fed in continuously by means of the feeder to the correct position. The subsequent working cycle is automatically controlled by means of the two-hand operated release device 12. The element blank placed against the stop 10 by means of the pneumatic holders 7 is then x2 by means of the locking mechanisms 5, at the same time as the upper guards 4 are lowered over the cutting zones. The saw blades are brought up through a slot in the work table, cut the element blank and return to the starting position. The upper guards 4, locksmith- || lll lH 'll II lll ll lll l lll l lll lll lll lll llll 10 15 512 403 4 nism 5 and the holders 7 then return, and the element blank is lifted by means of the roller conveyors 9 and tipped out behind the saws. Finally, end pieces and the like are removed by means of the device 15, preferably on the saw unit 1.
Rulltransportören 9, som är anordnad i förlängningen av rälsen 13, gör det möjligt att kapa korta ämnen och att eventuellt åstadkomma både raka och längsgående snitt i form av kilar.The roller conveyor 9, which is arranged in the extension of the rails 13, makes it possible to cut short blanks and to possibly make both straight and longitudinal cuts in the form of wedges.
Maskinerna kan också förses med ytterligare utrustning som ökar automatiserings- graden, med resultat att anordningen kan omvandlas till en programmerbar, hel- automatisk anordning för fiamställning av takstolselement. Detta kan åstadkommas genom t.ex. PC-styrning, och inmatningsvridbord (kapningsvinkel), tippningsmeka- nism för sågbladet, längdinställning samt in- och utmatning av ämnena på pneuma- tisk, hydraulisk eller eleknisk väg.The machines can also be equipped with additional equipment that increases the degree of automation, with the result that the device can be converted into a programmable, fully automatic device for fi adjustment of truss elements. This can be achieved by e.g. PC control, and feed turntable (cutting angle), tilting mechanism for the saw blade, length adjustment and input and output of the blanks by pneumatic, hydraulic or electrical means.
