Description
Den foreliggende oppfinnelse vedrører en maskinsag medThe present invention relates to a machine saw with
ett eller flere sagblader for kløyving av en stokk og én eller flere delekniver anordnet etter sagbladene. one or more saw blades for splitting a log and one or more cutting knives arranged after the saw blades.
Man kjenner for tiden til festeanordninger i maskinsager hvori styreanordninger, sagbladene og deleknivene er fast for-bundet i maskinsagen. Problemet med slike utførelser er at avstanden mellom de faststående styrepunkter som bearbeider treet, sett i sageretningen, blir så stor at saging i bue ikke lenger er mulig. Sagbladet eller -bladene følger således ikke treets lengdekrumning, men sager stokken etter den linje som de er per-manent montert i. Dette reduserer trevirkets utnyttelsesgrad betydelig. Fastening devices in machine saws are currently known in which the control devices, the saw blades and the cutting knives are firmly connected to the machine saw. The problem with such designs is that the distance between the fixed control points that process the wood, seen in the sawing direction, becomes so large that sawing in an arc is no longer possible. The saw blade or blades thus do not follow the longitudinal curvature of the tree, but saw the log along the line in which they are permanently mounted. This significantly reduces the utilization rate of the wood.
Formålet med oppfinnelsen er å avhjelpe den ovenfor anførte ulempe og frembringe en ny type maskinsag. The purpose of the invention is to remedy the above-mentioned disadvantage and to produce a new type of machine saw.
Maskinsagen ifølge oppfinnelsen er kjennetegnet ved at både sagbladene og deleknivene befinner seg i en separat enhet som er leddforbundet med maskinsagens ramme og som følger stokkens lengdekrumning. Sagenhetens leddforbindelse muliggjør saging i bue til og med ved saging av stokker med stor diameter, på grunn av at avstanden mellom de stasjonære styrepunkter i sageretningen er tilstrekkelig kort som følge av leddforbindelsen, The machine saw according to the invention is characterized by the fact that both the saw blades and the cutting knives are located in a separate unit which is articulated with the frame of the machine saw and which follows the longitudinal curvature of the log. The joint connection of the saw unit enables sawing in an arc even when sawing logs with a large diameter, due to the fact that the distance between the stationary control points in the sawing direction is sufficiently short as a result of the joint connection,
og sagbladene og delekniven kan under sagingen bedre følge treets lengdekrumning. and the saw blades and the dividing knife can better follow the longitudinal curvature of the wood during sawing.
Oppfinnelsen vil bli nærmere forklart i det etterfølgende under henvisning til den medfølgende tegning, hvor: Fig. 1 viser i sideriss en stokk som ligger mellom maskinsagens skjær og styreanordninger. Fig. 2 viser det samme som fig. 1, men med en annen utførel-sesform av sageenheten. The invention will be explained in more detail in what follows with reference to the accompanying drawing, where: Fig. 1 shows a side view of a stick which lies between the machine saw blade and control devices. Fig. 2 shows the same as fig. 1, but with a different embodiment of the sawing unit.
Maskinsagen omfatter, regnet i materetningen, trekkehjulThe machine saw includes, calculated in the feed direction, traction wheels
1, et selvsentrerende styreskinnesystem 2, barkeskjær 3, 4 som 1, a self-centering guide rail system 2, bark shears 3, 4 which
er roterbare om en horisontal aksel og en vertikal aksel, styreruller 5 samt en sageenhet 6. Sagblader 7 og delekniver 8 befinner seg i sageenheten 6 som er leddforbundet med maskinsagens ramme 9 og derved følger stokkens lengdekrumning. are rotatable about a horizontal axis and a vertical axis, guide rollers 5 and a sawing unit 6. Saw blades 7 and cutting knives 8 are located in the sawing unit 6 which is articulated with the machine saw's frame 9 and thereby follows the longitudinal curvature of the log.
I utførelsesformen i fig. 2 hører det til maskinsagen styreruller 10 som er anordnet foran sagbladene 7. Disse styreruller styrer sageenheten 6 i overensstemmelse med stokkens 11 lengdekrumning. Sageenheten 6 er leddforbundet til maskinsagens ramme 9 om en horisontal aksel 12, og den kan dessuten være leddforbundet svingbart om en vertikal akse 13 som er angitt med stiplet linje i fig. 2. In the embodiment in fig. 2 belong to the machine saw guide rollers 10 which are arranged in front of the saw blades 7. These guide rollers guide the saw unit 6 in accordance with the longitudinal curvature of the log 11. The saw unit 6 is articulated to the frame 9 of the machine saw about a horizontal shaft 12, and it can also be articulated pivotably about a vertical axis 13 which is indicated by a dashed line in fig. 2.
Som følge av bevegelsesmuligheten som sageenhetens 6 leddforbindelse medfører lykkes krum saging av stokken også med sir-kelsagblader 7 med stor diameter. As a result of the possibility of movement that the joint connection of the saw unit 6 entails, curved sawing of the log is also successful with circular saw blades 7 of large diameter.
Det.er klart for en fagmann i bransjen at oppfinnelsens forskjellige utførelsesformer kan variere innenfor rammen av de etterfølgende krav. Således kan sagbladenes 7 og deleknivenes 8 antall variere fra ett til flere. Avhengig av rettlinjetheten respektivt lengdekrumningen til stokken som skal sages kan sagbladet 7 og delekniven 8 under sagingen ifølge eksempelet ligge på linje med barkeskjærene 3, 4, som barker stokkens sider, eller de kan ligge på forskjellige linjer, dvs. at delekniven 8 er leddforbundet i forhold til sagbladet 7. It is clear to a person skilled in the art that the various embodiments of the invention may vary within the scope of the following claims. Thus, the number of saw blades 7 and cutting knives 8 can vary from one to several. Depending on the straightness or the longitudinal curvature of the log to be sawn, the saw blade 7 and the dividing knife 8 during the sawing according to the example can lie in line with the bark cutters 3, 4, which bark the sides of the log, or they can lie on different lines, i.e. the dividing knife 8 is articulated in relation to the saw blade 7.
