Abstract

The present invention relates to a method and to means in sawing, preferably in frame sawing. The method according to the invention is characterized in that the movement of the saw blade is compulsory guided along slides in such a way that the rearward part of the saw blade - seen in the moving direction thereof - is given a movement towards the work piece while the forward part of the blade at the same time is given a movement away from the work piece, at which the ratio between the movement of the saw blade towards respectively from the work piece and the total movement of the sawblade during one sawing cycle is within the range 7:100 - 1:100. The means according to the invention is characterized in at least two pair of slides (3, 4), along which the saw blade (2) is guided during its movement in both sawing directions, the angle between the slides is in the range between 172 DEG and 179 DEG .

Description

459 328 2 Huvudandamålet med föreliggande uppfinning år att åstadkomma en såg- ningsteknik som medger ramsågning av mycket tunna skivor ur ett såg- amne som kontinuerligt matas genom en losram. The main object of the present invention is to provide a sawing technique which allows frame sawing of very thin discs from a sawing blank which is continuously fed through a loose frame.

Ytterligare ett ändamål med uppfinningen är att åstadkomma en sågnings- teknik som medger optimala sågningsbetingelser för olika trädslag. Ännu ett ändamål med föreliggande uppfinning är att åstadkomma en såg- ningsteknik som ger mycket fina snittytor åven vid utsågning av extremt tunna f anérskivor ur ett sågämne.A further object of the invention is to provide a sawing technique which allows optimal sawing conditions for different tree species. Yet another object of the present invention is to provide a sawing technique which provides very fine cutting surfaces even when sawing extremely thin veneer sheets from a saw blank.

De ovan angivna ândamålen med uppfinningen uppnås genom att anord- ningen erhållit det i patentkravet angivna kånnetecknet.The above-mentioned objects of the invention are achieved by the device obtaining the key mark specified in the claim.

Genom att tvângsstyra såghladets rörelse utefter gejdrar på så sätt att bak- re delen av sågbladet - sett i sågbladets rörelseriktning - bibringas en rörelse i riktning mot ságåmnet medan bladets framre del samtidigt bi'- bringas en i huvudsak motsvarande rörelse iriktning från sågamnet. varvid förhållandet mellan sågbladets förflyttningsvåg i riktning mot resp. från såga mnet och sågbladets totala förflyttningsvåg ligger inom intervallet 7 : 100 och I : 100, har det överraskande visat sig möjligt. att ~ med tunna sàgblad utan skrånkriing och med effektiv spåntransport - såga ut extremt tunna skivor ur ett sågämne.By forcibly controlling the movement of the saw blade along guides in such a way that the rear part of the saw blade - seen in the direction of movement of the saw blade - is imparted a movement in the direction of the saw blade while the front part of the blade is simultaneously provided a substantially corresponding movement from the saw blade. wherein the ratio between the displacement wave of the saw blade in the direction of resp. from the saw mnet and the total displacement wave of the saw blade is in the range 7: 100 and I: 100, it has surprisingly proved possible. to ~ with thin saw blades without slanting and with efficient chip transport - saw out extremely thin discs from a saw blank.

Genom att ságningen endast sker utifrân sågämnets yttre begránsningsytor in mot sâgämnets centrum. förhindras effektivt en utfláckning vid såg- bladet utträde ur ämnet- Uppfinningen skall nu beskrivas i anslutning till utföringsexempel visade på bifogade ritningsblad. där Fig. l schematiskt visar ett neutralt utgångsläge av ett sàgblad och ett sâgåmne, Pig. 2 visar sågbladets ena ändiäge under sågning.By sawing only from the outer boundary surfaces of the saw blank towards the center of the saw blank. The invention will now be described in connection with exemplary embodiments shown in the accompanying drawing sheets. where Fig. 1 schematically shows a neutral starting position of a saw blade and a saw blank, Pig. 2 shows one end of the saw blade during sawing.

Fig. 3 visar ságbladets andra ândläge under sågning, och där Pig. 4 visar en perspektivvy av en uppsättning ságblad för en lösram av- sedd att arbeta i enlighet med tekniken enligt denna uppfinning. i fíg. l visas ságamnet l och ságbladet 2. Sâgbladet är styrt på geidrar 3 och 4. vilkas inbördes vinkel ar' mellan 172 0 och 179 O. [figuren har således denna vinkel, i áskâdliggörande syfte, visats starkt överdriven. 459 328 n J l f ig. 2 har sâgbladet 2 intagit ena åndläget samtidigt som sågämnet visats i läge för avverkande bearbetning. Det är således enbart den "bakre" delen av sågbladet 2 som kom mer i kontakt med sågämnet l under avverkning- en.Fig. 3 shows the second end position of the saw blade during sawing, and where Pig. 4 is a perspective view of a set of saw blades for a loose frame intended to operate in accordance with the technique of this invention. i fig. The saw blade 1 and the saw blade 2 are shown. The saw blade is guided on guides 3 and 4, the mutual angles of which are between 172 0 and 179 0. [The figure has thus shown this angle, for illustrative purposes, greatly exaggerated. 459 328 n J l f ig. 2, the saw blade 2 has assumed one breathing position at the same time as the saw blank is shown in the position for felling. It is thus only the "rear" part of the saw blade 2 that came into more contact with the saw blank 1 during the felling.

I fig. 3 visas det andra ändläget. dvs det läge varifrån avverkningen från det andra hållet just skall inledas. Att notera i samband med de olika såg- snittens 5 och 6 utseende. så har det "ideala" läget visats i figurerna. dvs det läge där avverkningen sker likformigt vid de båda snitten. Vid en såg- ning av ett sågämne med större dimension. dvs större mått i höjdled och med sam ma inställning av matningsbordet. kommer sågsnitten att bli olika stora. eftersom sågämnets mittlinie i höjdled kommer att ligga över såg- bladet mittpunkt. när detta befinner sig i ett neutralläge vinkelrätt mot sågämnet. l ändamål att uppnå optimala sågningsbetingelser för flera dim- ensioner, anordnas lämpligen matningsbordet inställbart i flera lägen.Fig. 3 shows the second end position. ie the position from which the felling from the other direction is just to begin. To note in connection with the appearance of the various saw cuts 5 and 6. then the "ideal" position has been shown in the figures. ie the position where the felling takes place uniformly at the two sections. When sawing a saw blank with a larger dimension. ie larger dimensions in height and with the same setting of the feeding table. the saw cuts will be different sizes. since the center line of the saw blank in height will be above the center of the saw blade. when this is in a neutral position perpendicular to the saw blank. In order to achieve optimal sawing conditions for several dimensions, the feeding table is suitably arranged adjustable in several positions.

I f lg. 4 visas en uppsättning sågblad för en lösram avsedd att utfora en sågning i enlighet med föreliggande uppfinning.I f lg. 4 shows a set of saw blades for a loose frame intended to perform a sawing in accordance with the present invention.

Uppf inningen är inte begränsad till ovan beskrivna utföringsexempel. utan modifikationer kan göras inom ramen för det följande angivna patentkra '- et.The invention is not limited to the embodiments described above. without modifications may be made within the scope of the following claims.
