Abstract

An amount of timber of the required size is collected in a compartment. The base of the compartment is then lowered to a transporter beneath the compartment so that the timber may be moved away. A component which seals the bottom of each compartment follows the bottom when it moves upwards and downwards. In the bottom lower position, the component is freed from it, allowing discharge of the timber from the compartment on to the transporter.

Description

453 645 För att avhjälpa ovan nämnda olägenheter är förfarandet enligt uppfinningen kännetecknat därav, att ett organ/ organ slutande varje facks botten bringas att följa bottnen då bottnen rör sig uppåt och nedåt och i bott- nens nedre läge frigöras från bottnen så, att virkespar- tiet kan lossas ur facket till transportören genom utrymmet mellan fackets vägg och transportören, där såsom i sorteringsanläggningen i det finska patentet 45155, fackens bottnar är anordnade att i enlighet med den uppsamlade virkesmängden sänka sig nedåt och då ett virkesparti av önskad storlek har uppsamlats nedsänkas till en nedanför belägen transportörs nivå eller under denna. På detta sätt åstadkommes ett varsamt lossande av virket från fackets botten, bullerstörningar minimeras och styckena lossas i en tämligen bra ordning. 453 645 In order to remedy the above-mentioned disadvantages, the method according to the invention is characterized in that a member / means closing the bottom of each compartment is caused to follow the bottom as the bottom moves up and down and in the lower position of the bottom is released from the bottom so that can be released from the compartment to the conveyor through the space between the compartment wall and the conveyor, where as in the sorting plant in Finnish patent 45155, the bottoms of the compartments are arranged to lower downwards in accordance with the collected amount of wood and when a timber batch of desired size has been collected a conveyor level below or below it. In this way a careful unloading of the wood from the bottom of the compartment is achieved, noise disturbances are minimized and the pieces are unloaded in a fairly good order.

Anordningen enligt uppfinningen är kännetecknad därav, att i samband med varje facks botten åtminstone ett slu- tarorgan är anordnat som är fästat i uppåt och nedåt rörliga leder och som är funktionsmässigt förenat med bottnen så, att bottnen då den rör sig uppåt och nedåt även förflyttar slutarorganet och i_ sitt nedre läge frigör slutarorganet så, att det fritt kan vrida sig runt sin led.The device according to the invention is characterized in that in connection with the bottom of each compartment at least one shutter member is arranged which is fastened in upwardly and downwardly movable joints and which is functionally connected to the bottom so that the bottom as it moves upwards and downwards also moves the shutter member and in its lower position releases the shutter member so that it can rotate freely around its joint.

Uppfinningen och dess funktion beskrivs härefter i detalj under hänvisning till den bifogade ritningen som visar ett utföringsexempel, till vilket uppfinningen inte skall begränsas.The invention and its function are hereinafter described in detail with reference to the accompanying drawing which shows an exemplary embodiment, to which the invention is not to be limited.

Figur 1 visar en sidovy av en sorteringsanläggning i vilken förfarandet och anordningen enligt uppfinningen tillämpas. 453 645 Figur 2 visar anordningens konstruktion i detalj.Figure 1 shows a side view of a sorting plant in which the method and the device according to the invention are applied. 453 645 Figure 2 shows the construction of the device in detail.

Figur 3 visar ett snitt längs linjen I - I i figur 2.Figure 3 shows a section along the line I - I in Figure 2.

Sorteringsanordningen för ságvirke enligt figur 1 omfattar en fördelningstransportör 1 och medbringare 2, med vilka virkestyckena förflyttas ovanför sorterings- fack 3a, 3b, 3c - 3j. På tidigare känt sätt nedfälls de med medbringarna 2 förflyttade virkesstyckena av olika sort i var sitt fack 3a - 3j, som begränsas av gedjer eller väggar 4, och vilkas övre yta övervakas t.ex. med en fotocell. Fackens bottnar Sa - Sj sänks i samma mån som virket A samlas i facken 3a - 3j. När ett virkes- parti A av önskad storlek har uppsamlats i ett av facken 3a - 3j, sänks fackets botten Sa - Sj till transportören 9, varvid även det stångformiga slutarorganet 8a - 8j i sina egna gejder lla - llj sänks tillsammans med virket A och med fackets botten. När ledernas gejder lla - llj upphör, stannar de stångformiga slutarorganens 8a - 8j led 12a - l2j. Medan fackets rörliga botten 5a - 5j fortsätter nedåt vrider det stångformiga slutarorganet 8a - 8j sig runt sin led 12a - l2j och efter det att slutarorganet har frigjort sig från styrorganet 7a - 7j på fackets botten är virket A fritt att lossas ur facket genom utrymmet mellan fackets vägg och transportören 9 till en kedjetransportör 9, medelst vilken virket A förs till vidarebehandling t.ex. via en keratt 10. När virket A under facken 3a - 3j har bortförts medelst kedjetrans- portören 9, vrids det stångformiga slutarorganet 8a - 8j till ett vertikalt läge, och då fackets botten Sa - 5j lyfts tar styrorganet pà fackets botten 7a - 7j med sig det stàngformiga slutarorganet och stänger fackets botten. 453 645 Figur 2 visar hur det stängformiga slutarorganet Ba i facket 3a lyfts tillsammans med fackets botten Sa och vrids runt sin led l2a pà grund av styrorganet 7a.The sorting device for sawing timber according to figure 1 comprises a distribution conveyor 1 and carrier 2, with which the timber pieces are moved above sorting compartments 3a, 3b, 3c - 3j. In a previously known manner, the pieces of timber moved with the carriers 2 are folded down into different compartments 3a - 3j, which are limited by goats or walls 4, and whose upper surface is monitored e.g. with a photocell. The bottoms Sa - Sj of the compartments are lowered to the same extent as the wood A is collected in compartments 3a - 3j. When a timber portion A of the desired size has been collected in one of the compartments 3a - 3j, the bottom Sa - Sj of the compartment is lowered to the conveyor 9, whereby also the rod-shaped shutter member 8a - 8j in its own guides 11a - 11j is lowered together with the timber A and with the bottom of the compartment. When the guides lla - llj of the joints cease, the joints 12a - l2j of the rod-shaped shutter members 8a - 8j stop. While the movable bottom 5a - 5j of the compartment continues downwards, the rod-shaped shutter member 8a - 8j rotates around its joint 12a - 12j and after the shutter member has released from the guide member 7a - 7j on the bottom of the compartment, the timber A is free to be released from the compartment through the space between the wall of the compartment and the conveyor 9 to a chain conveyor 9, by means of which the wood A is taken for further processing e.g. via a trough 10. When the timber A under the compartments 3a - 3j has been removed by means of the chain conveyor 9, the rod-shaped shutter member 8a - 8j is rotated to a vertical position, and when the bottom Sa - 5j of the compartment is lifted, the guide member takes the bottom 7a - 7j of the compartment closes the rod-shaped shutter member and closes the bottom of the compartment. 453 645 Figure 2 shows how the closed shutter member Ba in the compartment 3a is lifted together with the bottom Sa of the compartment and rotated around its joint l2a due to the guide member 7a.

I facket 3b visas hur virket A förflyttar det stàngfor- miga slutarorganet Bb längs sin gejd llb ner när fackets botten 5b sänks ned. I facket 3c visas fackets botten 5c i sitt öppningsläge. Det stångformiga slutarorganets Bc led l2c befinner sig i ändan av gejden llc. Styrorganet 7c pà fackets botten 5c frigör det stângformiga slutar- organet 8c och stänger samtidigt utrymmet mellan fackets botten 5c och transportören 9 så att virket A är fritt att lossas till transportören 9.The compartment 3b shows how the timber A moves the rod-shaped shutter member Bb along its guide 11b down when the bottom 5b of the compartment is lowered. In the compartment 3c, the bottom 5c of the compartment is shown in its opening position. The link lcc of the rod-shaped shutter member Bc is located at the end of the guide 11c. The guide means 7c on the bottom 5c of the compartment releases the rod-shaped shutter member 8c and at the same time closes the space between the bottom 5c of the compartment and the conveyor 9 so that the wood A is free to be unloaded to the conveyor 9.

Figur 3 visar en utföringsform av det stàngformiga slutarorganet 8a och dess gejdkonstruktion lla.Figure 3 shows an embodiment of the rod-shaped shutter member 8a and its guide construction 11a.

I utföringsexemplet är väggarna mellan facken eller gedjerna sluttande, men de kan också vara vertikala.In the exemplary embodiment, the walls between the compartments or the goats are sloping, but they can also be vertical.
