Description
115 20 2s_ , 30, 35 1sous297a7o_ som är inrättad att mäta träarbetsstyckenas bredd_före spån- anordningen,>är förskjutbara tvärs matningsriktningen i den önskade brädtjockleken motsvarande steg, så att träarbets- styckena under sin matning blir axelparallellt stegvis av- lplanade av spânverktygen. 1 Med arrangemanget enligt uppfinningen kan sågmaskinens och 'dess spånanordnings drift på enkelt sätt ordnas så att det inbördes avståndet mellan spånskärverktygen ständigt ökas eller _ minskas, så att ständigt väsentligen samma trävolym bortfräses resp. så att väsentligen samma bredd erhålls_på de genom *fräsning alstrade ytorna. Härvid är det utan vidare möjligt, att spånskärverktygens avstånd steglöst anpassas till arbets- styckets koniska form eller i steg, som motsvarar en bräd- tjocklek, anpassas till_koniciteten; K.Ett utföringsexempel på uppfinningen beskrivs i det följande _ under hänvisning till bifogade ritning, på vilken Fig. 1 uppifrån visar en sâgmaskin med två på avstånd från varandra anordnade spånskärande skivor och Fig. 2 visar ett tvärsnitt genom ett med maskinen enligt fig. 1 bearbetat rundträ. Which is arranged to measure the width of the wood workpieces before the chip device, are displaceable across the feed direction in the desired board thickness corresponding step, so that the wood workpieces during their feeding are axially parallel to the planar planes. With the arrangement according to the invention, the operation of the sawing machine and its chip device can be arranged in a simple manner so that the mutual distance between the chip cutting tools is constantly increased or decreased, so that constantly substantially the same volume of wood is milled away resp. so that substantially the same width is obtained on the surfaces generated by milling. In this case, it is readily possible for the distance of the chip cutting tools to be steplessly adapted to the conical shape of the workpiece or in steps corresponding to a board thickness to be adapted to the conicity; An embodiment of the invention is described in the following with reference to the accompanying drawing, in which Fig. 1 shows from above a sawing machine with two spaced-apart chip-cutting discs and Fig. 2 shows a cross-section through one with the machine according to Fig. 1. machined round wood.
Den i detalj icke närmare visade sågmaskinen-uppvisar flera likaxliga sågblad 3, mellan vilka med hjälp av matarvalsar 1 och 2 framförs ett rundvirkesstycke 4; Före detta aggregat är -anordnad en spånanordhing, vilken uppbär på en gemensam rota- tionsaxel 12 parvis anordnade spånskärverktyg 5. Vid passage genom sågbladen 3 uppstår en kantbit med parallella sidoytor 7. Med den tunnare änddelen främst skickas rundvirket 4 i bearbetningsriktning 8 först genom spånanordningen och dess verktyg 5. Därvid avverkar spånskärverktygen 5 från virkets oregelbundna sidkant 11 en trämängd i form av spån av lika fiberlängd, vilken utan sådan förbearbetning skulle ha sågats till bakar 9 av sågbladen 3. ' 10 _15 20 soos297F7 Då sidoavverkningen av spånskärverktygen 5 blir så stor under _bearbetningsförloppet, att denna avverkning tillåter bildan- det av en sidbräda, är anordnad en i form av två avkännarstift 15,16 utformad mätanordning. Denna samarbetar med en icke visad, hydraulisk eller pneumatisk anordning på sådant sätt, att avståndet mellan spänskärverktygen 5 under bearbetnings- förloppet eller passagen genom spånanordningen förstoras med dubbla brädmåttet 9 och dubbla snittfogtjockleken 10.The sawing machine, not shown in detail, has several equal-axis saw blades 3, between which a piece of round timber 4 is advanced by means of feed rollers 1 and 2; The former assembly is provided with a chip device hinge, which carries on a common axis of rotation 12 chip cutting tools arranged in pairs. When passing through the saw blades 3, an edge piece with parallel side surfaces 7 arises. With the thinner end part, the circular timber 4 is first sent through the chip device. and its tools 5. Thereby the chip cutting tools 5 cut from the irregular side edge 11 of the wood a quantity of wood in the form of chips of equal fiber length, which without such pre-processing would have been sawn into bakers 9 by the saw blades 3. When the side felling of the chip cutting tools 5 becomes so large during the processing process, that this felling allows the formation of a side board, a measuring device designed in the form of two sensor pins 15, 16 is arranged. This cooperates with a hydraulic or pneumatic device (not shown) in such a way that the distance between the clamping tools 5 during the machining process or the passage through the chip device is increased by double the board dimension 9 and the double section joint thickness 10.
Vid det visade utföringsexemplet är det så anordnat, att rund- virket 4 sänds.genom bearbetningsmaskinen med sin tunnare än- de främst och att därvid pá de med 6 betecknade ställena det axiella avståndet mellan de båda spânskärverktygen 5 ökas stegvis med varje gång en brädtjocklek 9. På detta sätt hålls träförlusten mycket låg och uppnås en större andel sågat virke.In the embodiment shown, it is arranged that the round timber 4 is sent through the processing machine with its thinner end mainly and that in the places denoted by 6 the axial distance between the two chipping tools 5 is increased stepwise with each time a board thickness 9 In this way, the wood loss is kept very low and a larger proportion of sawn timber is achieved.
En ytterligare väsentlig fördel består däri, att driveffekteni för spånskärverktygen 5 kan hållas förhållandevis låg, i synnerhet som ständigt väsentligen samma trävolym bortfräses och de genom fräsning alstrade ytorna håller väsentligen samma bredd.A further significant advantage consists in that the drive efficiency of the chip cutting tools 5 can be kept relatively low, in particular when substantially the same volume of wood is milled away and the surfaces generated by milling have substantially the same width.
I stället för en mekanisk avkännaranordning 15,16 kan också en kapacitiv gränsavkännare eller en fotooellavkännare vara anordnad.Instead of a mechanical sensor device 15,16, a capacitive limit sensor or a photoelectric sensor can also be provided.
