Abstract

The plant is used for feeding boards of timber (4) to and through a single board feeder (2). It has elongated boards of timber which lie sequentially on a conveyor (1) transversely to the longitudinal axis of the conveyor wherein the conveyor advances the boards to the single-board feeder at a speed Vin. The feeder operates at a board-feeding speed which is lower than Vin. A regulator (5,6) is mounted upstream of the board feeder and the buffer region (3) in the proximity as seen in the conveying direction wherein. The regulator retards the boards advanced on the conveyor to a speed Vreg which is slower than Vin prior to the boards being conveyed further to the board feeder on the conveyor.

Description

15 20 25 30 5 0 7 2 6 5 r 2 exempelvis av den typ som görs till föremål i svenska patentansökningen 9601389-1. 15 20 25 30 5 0 7 2 6 5 r 2 for example of the type made the subject of Swedish patent application 9601389-1.

Transportören 1 förflyttar sålunda tvärs transportriktningen liggande virkesstycken 4 med hastigheten Vin. Normalt är virkesstyckena 4 ej jämnt fördelade på transportören 1 utan kan uppvisa mer eller mindre stora avstånd från varandra. Detta antyds till vänster i figuren.The conveyor 1 thus moves timber pieces 4 lying across the transport direction at the speed Vin. Normally the pieces of wood 4 are not evenly distributed on the conveyor 1 but can have more or less large distances from each other. This is indicated on the left in the figure.

Eftersom enstycksmataren 2 skall mata virkesstycken ett och ett på en medbringarförsedd vidaretransportör, antydd till höger i figuren, måste en viss virkesbuffert 3 föreligga uppströms enstrycksmataren, vilken buffert erhålles genom att V", är större än Vm, som tidigare antytts. Det här beskrivna utgör i sig känd teknik, varför en närmare detaljerad redogörelse härav ej synes nödvändig.Since the one-piece feeder 2 is to feed pieces of wood one by one on a carrier-supplied further conveyor, indicated on the right in the figure, a certain wood buffer 3 must be present upstream of the one-piece feeder, which buffer is obtained by V "being larger than Vm, as previously indicated. technology known per se, so that a more detailed account of this does not seem necessary.

Med hjälp av uppfinningen kan nämnda buffertområde 3 hållas inom en kontrollerad storlek. Framför eller uppströms enstycksmataren 2 är anordnad en regulator med utefter transportörens 1 bredd fördelade, ändlösa band 5, vart och ett styrt över brythjul 6, av vilka ett är drivet. Det ändlösa bandets 5 övre part befmner sig över transportörens 1 övre transportplan och kommer sålunda att ingripa med virkesstyckena 4.By means of the invention, said buffer area 3 can be kept within a controlled size. Arranged in front of or upstream of the one-piece feeder 2 is a regulator with endless belts 5 distributed along the width of the conveyor 1, each controlled over break wheels 6, one of which is driven. The upper part of the endless belt 5 is located above the upper transport plane of the conveyor 1 and will thus engage with the pieces of wood 4.

Som antyds på ritningen skall den övre parten av bandet 5 röra sig i transportörens 1 transportriktning och bandets 5 hastighet är VM, vilken hastighet är mindre än transportörens 1 hastighet Vin. De på transportören 1 transporterade och oregelbundet fördelade virkesstyckena 4 kommer vid transporten att gripas eller bromsas av banden 5, på grund av hastighetsskillnaden mellan Vi, och VM. På bandens 5 övre part kommer sålunda en förbuffert 3' av virkesstycken att byggas upp samtidigt som regulatoranordningen fördröjt kommer att avge de på denna sig samlande virkesstyckena till transportanordningen 1 .före enstycksmataren 2, när dennas buffert 3 så påkallar. Förbufferten 3' kan tillåtas växa eller byggas ut uppströms framför regulatorn till viss grad. Trots att sålunda virkesstyckena vidaretransporteras till enstycksmataren 2 på transportören 1 med hastigheten V-m erhålles i jämförelse med transportörens 1 takt en utjämnad pábyggning av buffertområdet 3 framför enstycksmataren 2, dvs. en påbyggning som håller sig inom största och minsta tillåtna utsträckning. Demia uppbromsning av virkesstyckena och frammatning till enstycksmataren 2 är möjlig genom att utnyttja luckoma mellan virkesstyckena på transportören 1 före regulatoranordningen. Uppfnningen gör det sålunda även möjligt, att under viss kortare tid fortsätta att bygga upp förbufferten 3' liksom bufferten 3 framför enstycksmataren 2, även om denna stoppats exempelvis på grund av produktionsstopp nedströms, efter enstycksmataren. Regulatoranordningen kan göras anpassbar till olika transponhastigheter #507 265 3 hos transportören 1 liksom för olika virkesdirnensioner och kapacitet hos enstycksmataren.As indicated in the drawing, the upper part of the belt 5 should move in the conveying direction of the conveyor 1 and the speed of the belt 5 is VM, which speed is less than the speed Vin of the conveyor 1. The pieces of wood 4 transported on the conveyor 1 and irregularly distributed will during the transport be gripped or braked by the belts 5, due to the speed difference between Vi and VM. Thus, on the upper part of the belts 5, a pre-buffer 3 'of pieces of wood will be built up at the same time as the regulator device will delay the delivery of the pieces of wood collecting on it to the transport device 1 before the one-piece feeder 2, when its buffer 3 so requires. The pre-buffer 3 'can be allowed to grow or expand upstream in front of the regulator to a certain extent. Thus, despite the fact that the pieces of wood are further transported to the one-piece feeder 2 on the conveyor 1 at the speed V-m, in comparison with the conveyor 1's pace, a smoothed build-up of the buffer area 3 in front of the one-piece feeder 2 is obtained, i.e. an extension that stays within the maximum and minimum permitted extent. Demia braking of the timber pieces and feeding to the one-piece feeder 2 is possible by utilizing the gaps between the timber pieces on the conveyor 1 before the regulator device. The invention thus also makes it possible, for a certain shorter time, to continue to build up the pre-buffer 3 'as well as the buffer 3 in front of the one-piece feeder 2, even if this has been stopped, for example due to production stoppage downstream, after the one-piece feeder. The regulator device can be made adaptable to different transpon speeds # 507 265 3 of the conveyor 1 as well as to different timber dimensions and capacity of the one-piece feeder.

Normalt skall regulatorns hastighet VM ligga mellan Vi" och Vw. Genom uppfinningen har sålunda âstadkommits en mycket flexibel anordning, möjlig att installera i befintliga anläggningar för att lösa ett allvarligt problem som föreligger, särskilt vid högproduktiva anläggningar. Banden kan i princip vara av vilken typ och av vilket material som helst, även kedjor med hög friktion, förutsättningen är att de sänker virkesstyckenas hastighet till hastigheten V",Normally the speed VM of the controller should be between Vi "and Vw. The invention has thus provided a very flexible device, possible to install in existing plants to solve a serious problem which exists, especially in highly productive plants. The belts can in principle be of the type and of any material, including high friction chains, provided that they lower the speed of the pieces of wood to the speed V ",
