Description
Uppfinnare: V T Niku Prioritet begard frdn den 6 angusti 1957 (Finland) Foreliggande uppfinning hanfor sig till en anordning vid enstocks-barkningsmaskiner, dar hittills losskarningen av barken for framstallning av ren vara har vallat stora svarigheter, till och med i sadan grad att en efterbarkning ofta är nadvandig. Med foreliggande uppfinning kan denna nackdel, som visat sig huvudsakligen hero pa fiberns seghet i sin fiberriktning, d. v. s. i virkets langdriktning, undvikas genom enkla medel. Inventor: VT Niku Priority was applied from 6 August 1957 (Finland). is often present. With the present invention this disadvantage, which has been found mainly due to the toughness of the fiber in its fiber direction, i.e. in the longitudinal direction of the wood, can be avoided by simple means.
Barkningsmaskiner aro aven kanda, som ha med ander eller dylikt forsedda tandhjul, som rotera och satta stocken i rotation. i samma riktning. Vidare finnas olika anordningar for stockens frammatning. Ytterligare en. typ av barkningsmaskin är kind, som har en driven ring, dar med motvikter forsedda klingor med hjalp av centrifugalkraften tvingas mot stocken och en del av klingorna skar barken i spiraler, medan en. annan del av klingorna sedan skrapar bort den i spiral skurna barken. Dessa kanda maskintyper ha emellertid icke tillfredstallande effektivitet. Barking machines are also known as having gears or similar gear wheels, which rotate and set the log in rotation. in the same direction. Furthermore, there are various devices for feeding the log. Further. type of barking machine is the cheek, which has a driven ring, where blades provided with counterweights by means of the centrifugal force are forced against the log and some of the blades cut the bark into spirals, while one. another part of the blades then scrapes off the spirally cut bark. However, these known machine types have unsatisfactory efficiency.
Anordningen enligt uppfinningen Urinetecknas till skillnad haxifran i huvudsak av att i densamma i stockarnas rorelsebana framfor de egentliga barkningsklingorna eller -knivarna aro anordnade en eller flera i forhallande till matningsriktningen tvarstaende, vid en fritt roterande, stocken omslutande ringformig hallare fastsatta skarklingor eller lmivar, som i forhaRande till matningsriktningen aro sa snett anbragta, att stocken vid sin framatghende rorelse bibringar hallaren med knivarna en rotationsrorelse kring stocken, varjamte knivarna aro pa sá satt fjaderpaverkade, att de strava att installa sig och kvarbli i narheten av matningsbanans centrum, for att till Raj d harav skara barken i form av en spiral resp. flera spiraler innan stocken inkommer mellan de egentliga barkningsknivarna far att avbarkas. The device according to the invention is distinguished from the haxifran, mainly in that in it in the path of movement of the logs in front of the actual barking blades or knives there are arranged one or more in the relation to the feeding direction related to the direction of feeding, they are so obliquely arranged that the log, in its forward movement, causes the holder with the knives to rotate around the log, and the knives are so spring-loaded that they strive to position themselves and remain close to the center of the feeding path. of which cut the bark in the form of a spiral resp. several spirals before the log enters between the actual barking knives must be debarked.
Ett utforingsexempel, till vilket uppfinningen dock joke är begransad, visas pa bifogade ritning, dar fig. 1 visar en anordning enligt uppfinningen, sedd i barkningsmaskinens frammatningsriktning, och fig. 2 är en sektion av anordningen enligt fig. 1 och visar tvenne diametralt motsatta knivar eller klingor. An exemplary embodiment, to which the invention is, however, joke limited, is shown in the accompanying drawing, in which Fig. 1 shows a device according to the invention, seen in the feed direction of the debarking machine, and Fig. 2 is a section of the device according to Fig. 1 and shows two diametrically opposite knives or blades.
Pa ritningen betecknar 1 en i maskinen framfor de egentliga barkningsknivarna eller -klingorna fast stodring. 2 avser en av ringen 1 stodd, fritt roterande styrning. Ringarna 1 och 2 aro foretradesvis forsedda med styrskenor 3 och ett mot dessa svarande spar 4 och ringen 2 roterar i ringen 1, lagrad i kullager 5. En flans 6, som är fast i ringen 1, hindrar att ringen 2 kan lossna fran ringen 1. I styrringen 2 fir med skruvar fast en fastring 8 for knivarna, och vid denna ring Er i sin tur en fastplatta 9 anbragi (fig. 2). Fastplattan 9 är forsedd med en fjadertapp 10 med ett spar 11, i vilken fjaderns 12 fria ande är anbragt och fastspand med hjalp av en mutter 13 (fig. 2). Fastplattan 9 är dessutom forsedd med ett begransningsanslag 14, som begransar fjaderns 12 rorelse. Fjaderns 12 motsatta ande 15 ar omvriden cirka 90° och i denna ande är en skarklinga eller -kniv 18 fastsatt med skruvar 16 och en fastskiva 17. In the drawing, 1 denotes a fixed support in the machine in front of the actual barking knives or blades. 2 refers to a freely rotating guide supported by the ring 1. The rings 1 and 2 are preferably provided with guide rails 3 and a corresponding groove 4 and the ring 2 rotates in the ring 1, mounted in ball bearings 5. A flange 6, which is fixed in the ring 1, prevents the ring 2 from coming loose from the ring 1 In the guide ring 2 a fastening ring 8 for the knives is fastened with screws, and at this ring a fastening plate 9 is in turn fitted (fig. 2). The fixed plate 9 is provided with a spring pin 10 with a groove 11, in which the free spirit of the spring 12 is arranged and clamped by means of a nut 13 (Fig. 2). The fixed plate 9 is also provided with a limiting stop 14, which limits the movement of the spring 12. The opposite spirit 15 of the spring 12 is rotated about 90 ° and in this spirit a shear blade or knife 18 is fixed with screws 16 and a fixed disc 17.
Fjadrarna 12 kvarhalla knivarna 18 riktade mot styrringens 2 centrum. Yid frammatning av en stock pressas dess ande mot fjadrarna 12, som harvid bojas i matningsriktningen sa att stocken inkommer Indian knivarna 18, som foretradesvis aro anordnade under paverkan av en sadan avpassning av fjadrarnas langd, deras b5jning och/eller fastg5ringsstalle, att knivarna komma att ligga i olika plan i forhallande till matningsriktningen. Knivarna 18 med sina fasten 17 aro sâ snett riktade i forhallande till matningsriktningen, att de vid inmatning av stocken tvinga styrringen 2 att rotera kring stocken pa sã satt, att varje kniv skar sitt spar i barken. The springs 12 retain the knives 18 directed towards the center of the guide ring 2. When advancing a log, its spirit is pressed against the springs 12, which are then bent in the feeding direction so that the log enters the Indian knives 18, which are preferably arranged under the influence of such an adjustment of the length of the springs, their bending and / or fastening stall, that the knives lie in different planes in relation to the feeding direction. The knives 18 with their fasteners 17 are so obliquely directed in relation to the feeding direction that, when feeding the log, they force the guide ring 2 to rotate around the log in such a way that each knife cuts its groove in the bark.
Likasa kunna knivarna 18 fastas vid styva, av fjadrar pfiverkade stanger och uppfinningen. kan awn i ovrigt- forandras I konstruktivt 2— — hanseende, utan att uppfinningens ram darigenom. overskrides. Similarly, the knives 18 can be attached to rigid, spring-loaded rods and the invention. can awn in other- change In constructive 2— - hanseende, without the framework of the invention thereby. exceeded.
I modifierad form kan anordningen enligt uppfinningen naturligtvis A.ven anvandas for sadana barkningsmaskiner, dar stocken vid sin frammatning bringas i rotationsrorelse. In a modified form, the device according to the invention can of course also be used for such debarking machines, where the log is caused to rotate in its feed.
Man kan aven anordna tva eller flera anordningar enligt uppfinningen efter varandra,varyid knivarna i varje ring skara en eller flera spiraler i olika riktningar, varyid barken lossnar Yid barkningsknivarna i form ay sneda rutor. Man kan aven tanka sig, att den bark, som skurits med anordningen enligt uppfinningen i motriktade spiraler, lossnar fran stockytan till fOljd ay krympningen genom torkning da stockarna lagras. One can also arrange two or more devices according to the invention one after the other, varyid the knives in each ring cut one or more spirals in different directions, varyid the bark loosens Yid the barking knives in the form of oblique squares. It is also conceivable that the bark, which is cut with the device according to the invention in opposite spirals, detaches from the log surface as a result of the shrinkage by drying when the logs are stored.
