CLASS INTERNATIONAL SWEDISH B27 I38 1: 1 PATENT AND REGISTRATION AGENCY Ans. 11 049/1960 received on 16/11 1960 taken on 14/6 196 E RUPPERT ocx S KASTENMULLER, SA.UERLACH, THE FEDERAL REPUBLIC OF GERMANY Barking tax for barking machines Priority requested before 18 November 1959 (Federal Republic of Germany) The present invention relates to a barking invention. especially leaner logs.

Barkningsmaskiner aro kanda, vilka barka timmer med ett verktyg bestaende av en kedja (katting) med lankar av rundmaterial. Med sadana kedjor kan man emellertid endast tillfredsstallande barka rundtimmer av grovre dimensioner och likasa ar en renputsning mojlig endast pa friskt men inte pa torrt timmer, vid vilket senare bark och bast sarskilt starkt hafta vid traet. Barking machines aro kanda, which bark timber with a tool consisting of a chain (katting) with links of round material. With such chains, however, it is only possible to satisfactorily bark round timber of coarser dimensions, and likewise a clean-up is possible only on fresh but not on dry timber, in which case the later bark and bark are particularly strongly adhered to the wood.

Uppfinningen har till an dam M upphavandet av dessa nackdelar. Till losande av uppgiften. aro ett fiertal kattingar spanda i jamn delning mellan tva motordrivna och kring en mot arbetsstyeket tvarstalld axel roterbara skivor, varvid kattingen bestar av lankar av kantigt profilmaterial. Sarskilt lamplig har en fyrkants- till sexkantssektion visat sig. The invention has, for example, the origin of these disadvantages. To solve the task. a number of kittens spand in an even division between two motor-driven and about a disk rotatable towards the workpiece axis, the kitten consisting of ridges of angular profile material. A square to hexagonal section has proved to be particularly suitable.

Vid en foredrageii utforingsform aro Iankarna cirkelrunda och rtirligt hoplankade, sa att de under barkningen kunna vrida sig gentemot varandra. In a preferred embodiment, the anchors are circular and vertically joined together, so that during barking they can turn towards each other.

Pa bifogade ritning askadliggores schematiskt en barkningsanordning for rundtimmer enligt uppfinningen, varvid fig. 1 visar en frontvy, fig. 2 en sidovy, fig. 3 en del av en barkningskedja och fig. 4 en avskuren kedjelank. In the accompanying drawing, a debarking device for round timber according to the invention is schematically damaged, Fig. 1 showing a front view, Fig. 2 a side view, Fig. 3 a part of a debarking chain and Fig. 4 a cut chain link.

Barkningskedjor 2 aro spanda mellan tva gavlar 3 till bildande av en trumma 1. Gavlarna 3 aro vridbara kring en axel 4 och stocken som skall barkas infores i trummans tvarriktning. Kedjorna 2 aro med lika delning utbytbart fasta utefter cirkellinjer pa gavlarna 3. Barkningstrumman 1 roterar normalt i pilens F riktning och stocken utfor en langd rorelse i pilens P riktning. Pa ber8rings- och barkningsstallet blir det darfor motriktad rOrelse. Mojlighet finns emellertid ()Asa att arbeta med en med timrets rorelse medriktad rotation. av trumman enligt den streckade pilen, om rotationshastigheten är tillrackligt hog. Stocken 5 kan forutom sin langdrorelse aven ha en vridningsrorelse, t. ex. i pilens D riktning, kring sin Iangdaxel A. Vid det visade exemplet transporteras stocken pa rullar 6. Barkningstrumman 1 ar hojdinstallbar och svangbart lagrad i bararmar 7, varigenom anpassning till stockens tjocklek och erforderligt arbetstryck kan astadkommas. Drivningen sker med en rem 8 och remskiva 9. Barking chains 2 are stretched between two ends 3 to form a drum 1. The ends 3 are rotatable about a shaft 4 and the log to be barked is inserted in the transverse direction of the drum. The chains 2 are with equal division interchangeably fixed along circular lines on the ends 3. The barking drum 1 normally rotates in the direction of the arrow F and the log performs a long movement in the direction of the arrow P. At the touch and barking stall, there is therefore a counter-movement. However, it is possible () Asa to work with a rotation oriented with the movement of the timer. of the drum according to the dashed arrow, if the rotational speed is sufficiently high. The log 5 may, in addition to its longitudinal movement, also have a torsional movement, e.g. in the direction of the arrow D, around its longitudinal axis A. In the example shown, the log is transported on rollers 6. The barking drum 1 is height-adjustable and pivotally mounted in bar arms 7, whereby adaptation to the log thickness and required working pressure can be achieved. The drive is done with a belt 8 and pulley 9.

Enligt uppfinningen besta barkningskedj orna av lankar av kantigt profilmaterial. I fig. 4 visas en kedjelank 10 av fyrkantsmaterial, och lankarna aro enligt fig. 3 cirkelrunda och sit hoplankande, att de aro utan fast forbindelse med varandra och darfor rorliga inbi5rdes. Darigenom kunna lankarna under barkningen vrida sig sit att ojamn slitning forebygges. Genom lankarnas runda form \dunes framfOr alit att aven fordjupningar i rundvirket bear-betas och barkas fullstandigt rena. De kantiga kedjelankarna angripa, nar de traf fa ytterytan pa rundvirket, med sina skarpa kanter barken och basten effektivt, sit att bark och bast aven vid torrt virke battre och snabbare kunna avlagsnas Iran stocken. Kedjorna enligt uppfinningen sdkerstalla ocksa att de under i basten ofta befintliga anhopade trafibrerna, som for den vidare bearbetningen jute aro onskvarda, likaledes avlagsnas, sit att traet battre an hittills kan renputsas och sax-skill val kommer att lampa sig fOr pappersoch cellulosaindustrin. 2 Uppfinningen är inte begransad till det visade utforingsexemplet. Man kan i stallet for kedjelankar av fyrkantsmaterial aven anvanda sadana av annat kantigt material. Aven orunda lankar, t. ex. ovala eller i ovrigt Fangstrackta, kunna anvandas. According to the invention, the barking chains consist of strands of angular profile material. Fig. 4 shows a chain link 10 of square material, and the links are according to Fig. 3 circular and planking together, that they are without fixed connection with each other and therefore movable. As a result, the flaps can be twisted during barking to prevent uneven wear. Due to the round shapes of the lanes, it is important that depressions in the round timber are also processed and barked completely clean. The angular chain anchors attack, when they hit the outer surface of the round timber, with their sharp edges the bark and the bark effectively, so that the bark and bark even with dry wood can be better and faster removed from the Iran log. The chains according to the invention also ensure that the accumulated fibrils, which are often present in the bast, which for further processing are jute, are also removed, so that the wood can hitherto be cleaned better and scissors-skill choices will be suitable for the paper and cellulose industry. The invention is not limited to the exemplary embodiment shown. Instead of chain anchors of square material, such other angular material can also be used. Aven orunda lankar, t. Ex. oval or otherwise Captive, can be used.
