Abstract

A device for securing sawn timber as it is trimmed in length or divided, comprising a supplementation of the feed system by a similar system of securing elements, turned inside out towards the dogs of the drive mechanism and coupled together with the feed system in such a way that the securing chains are able to go forwards at the same or lower speed than the feed system but absolutely no quicker. The timber is thereby clamped between the dogs of the feed system and the securing elements. <IMAGE>

Description

PROBLEMSTÄLLNING Föreliggande uppfinning avser utrustning för att hålla fast virket vid bearbetning, automatiskt justerande till alla i sortimentet förekommande dimensioner. PROBLEM STATEMENT The present invention relates to equipment for holding the wood during processing, automatically adjusting to all dimensions present in the range.

PROBLEMLÖSNING Den till grund för uppfinningen liggande målsättningen uppnås om den inledningsvis antydde anordningen kännetecknas därav att fasthållningskedjan är drivbar av det av kedjesystemet frammatade virket och att drivanordningen innefattar en backspärr, vilken är anordnad att hindra att fasthållnings- kedjan går fortare än kedjesystemet men att tillåta att den står stilla eller går saktare än kedjesystemet.TROUBLESHOOTING The object underlying the invention is achieved if the device initially indicated is characterized in that the retaining chain is drivable by the timber fed by the chain system and that the drive device comprises a backstop, which is arranged to prevent the retaining chain from moving faster than the chain. it is stationary or slower than the chain system.

RITNINGAR Uppfinningen skall beskrivas närmre under hänvisning till bifogade ritningar på vilka: Fig l visar en schematisk sidovy av uppfinningsföremålet och Fig 2 visar uppfinningsföremålet schematiskt uppifrån.DRAWINGS The invention will be described in more detail with reference to the accompanying drawings, in which: Fig. 1 shows a schematic side view of the object of the invention and Fig. 2 shows the object of the invention schematically from above.

FÖREDRAGEN UTFÖRINGSFORM Anordningen består av ett vanligt kedjesystem l, för fram- tagning, kompletterad med kedjor med fasthållningsdon, 3, kallade fasthållningskedjor, 2. Dessa fasthållningskedjor är relativt korta. Avsikten är att förhindra kast vid själva bearbetningen av virket.PREFERRED EMBODIMENT The device consists of a standard chain system 1, for development, supplemented with chains with holding devices, 3, called holding chains, 2. These holding chains are relatively short. The intention is to prevent throws during the actual processing of the wood.

Från drivstation för frammatningskedjorna 4, utgår drivning av fasthållningskedjorna 2, på sådant sätt att fasthållnings- kedjorna 2, kan stanna eller gå saktare eller lika framåt som *Y 3 drivkedjorna men inte fortare framåt.From the drive station for the feed chains 4, drive of the retaining chains 2 starts in such a way that the retaining chains 2 can stop or go slower or as forward as the * Y 3 drive chains but not faster forward.

Detta kan t ex åstadkommas medelst backspärr 5. Fasthàll- ningskedjorna kan bromsas eller växlas så att önskat grepp erhålles.This can be achieved, for example, by means of backstop 5. The retaining chains can be braked or shifted so that the desired grip is obtained.
