Liimauspuristin - Limningspress ' Tåinå keksintd koskee laitetta liimapalkkiaihioiden purista- 5 miseksi liimauksen ajaksi liimapalkkien muodostamiseksi.The present invention relates to an apparatus for pressing glue beam blanks during gluing to form glue beams.
Liimapalkilla tarkoitetaan tåsså yhteydesså pååasiassa useammasta sahatavarakappaleesta poikkileikkaukseltaan joko suorakaiteen tai lopullista profiilia vastaavaan muotoon 10 håylååmållå ja liimaamalla valmistettuja mååråpituisia "palkkeja". Tåmåntyyppisille liimapalkeille pyritåån yleenså aikaansaamaan estettlsesti virheeton ulkonåko. Nåistå liima-palkeista voidaan esimerkiksi valmistaa ns. liimalevyjå, jolloin liimapalkista vannehalkaisusahalla viipaloidaan lii-15 malevyjå.Glulam in this context means mainly "beams" of several lengths made of several pieces of lumber with a cross-section, either rectangular or in the shape corresponding to the final profile, by means of a rake and gluing. For these types of adhesive beams, the aim is usually to achieve an unobstructedly flawless appearance. From these glue beams, for example, so-called glue sheets, in which case glue-15 is sliced from the glue beam with a band-splitting saw.
Liimapalkkien valmistuksessa raakasahatavarasta poistetaan viat katkaisemalla ja nåin saadut virheettdmåt kappaleet jatketaan sormiliimausliitosta kåyttåen ja katkaistaan måå- 20 råpituisiksi, jotka kappaleet sitten h6ylåtåån ja liimataan lappeelta aihioiksi. Nåiden aihioiden liimauksessa kåytetåån usein l-tasoisia puristimia vanhojen sakara- ja kolmiolii- mauspuristinten ohessa ja tehoa yritetåån lisåtå suurtaa- juus- tai muuta låmmitystå apuna kåyttåen. Sakara- ja kol- 25 mioliimauspuristimet, jotka ovat ns. pyoriviå, ovat hankalia siksi, ettå liimoitettujen tyfikappaleiden ladonta niihin ja liimautuneiden aihioiden poisto niistå tapahtuu kåsin, koska nåiden tyovaiheiden jårjeståminen koneellisesti tapahtuvaksi on vaikea toteuttaa. Kåsin ladonta ja liimattujen aihioiden 30 poisto on fyysisesti rasittavaa ja aikaa viepåå ja siksi . . liimaustehot edellå kuvatuissa puristimissa jååvåt pieniksi.In the manufacture of glued beams, defects are removed from the raw sawn timber by cutting and the defect-free pieces thus obtained are extended using a finger-gluing joint and cut to length, which pieces are then discarded and glued from the flap to blanks. In the gluing of these blanks, L-level presses are often used in addition to the old square and triangular gluing presses, and attempts are made to increase the power by using high-frequency or other heating. Squeegee and triangular gluing presses, which are so-called round, are cumbersome because the stacking of the glued nitrogen pieces in them and the removal of the glued blanks from them takes place manually, because it is difficult to arrange these work steps to take place mechanically. Manual stacking and removal of glued blanks 30 is physically strenuous and time consuming and therefore. . the gluing powers in the presses described above remain small.

Eråån edullisen sovellutusmuodon mukaan jokaista puristuskitaa rajoittaa ensimmåinen kiinteå vaste ja puristuselin, joka esimerkiksi voi kåsittåå letkun, jolla puristuspaine aikaansaadaan paineilmaa tai painevettå kåyttåen, jolloin 20 mainittu letku on sovitettu toisen kiinteån vasteen ja liik-kuvan vasteen våliin, joka liikkuva vaste vaikuttaa aihio-pinkan uloimpaan kappaleeseen. Tåll6in kidan vålin muodostaa ensimmåinen kiinteå vaste ja liikkuva vaste.According to a preferred embodiment, each compression die is limited by a first fixed response and a compression member, which may, for example, comprise a hose for applying compression pressure using compressed air or pressurized water, said hose being fitted between the second fixed response and the moving response. to the outermost paragraph. In this case, the first fixed response and the moving response form between the gills.
25 Keksinnon mukaisesti aihiopinkkojen liimoitus ja ladonta tehdåån itse liimauspydrån puristinkitojen ulkopuolella, mikå mahdollistaa liimauslaitteen automatisoinnin.According to the invention, the gluing and stacking of the blank stitches is carried out outside the press stitches of the gluing machine itself, which enables the automation of the gluing device.
Keksintoå kuvataan seuraavassa låhemmin viittaamalla ohei-30 seen piirustukseen, jossa kuvio 1 esittåå pystyleikkauskuvaa keksinndn mukaisesta lii-mauspuristimesta ja kuvio 2 esittåå samaa rakennetta kuin kuvio 1 pååltåpåin 35 katsottuna.The invention will now be described in more detail with reference to the accompanying drawing, in which Fig. 1 shows a vertical sectional view of a gluing press according to the invention and Fig. 2 shows the same structure as Fig. 1 seen from above.
Kuvioissa on 6-kulmainen 1iimauspy6rå merkitty viitenumerol- la 1. Liimauspydrå 1 on pydritettåvisså vaakasuoran akselin • · 92026 3 ympåri ja sen pituus vastaa pååasiassa valmistettavan liima-palkin pituutta. 6-kulmaisen liimauspydrån 1 jokaisessa ul-kokulmassa on poikkileikkaukseltaan kolmion muotoinen kiin-teå vaste 5 ja 6. Liimoitettu aihiopinkka 2 on tarkoitus 5 sovittaa puristuskitaan 3, jota rajoittaa kiinteå vaste 5 ja liikkuva vaste 7. Liikkuvan vasteen 7 ja toiseii kiinteån vasteen 6 våliin on sovitettu letku, esimerkiksi paloletku 4, jolla puristuspaine aikaansaadaan paineilmaa tai paine-vettå kåyttåen. Letkun 4 ohella voidaan kåyttåå myås muun 10 tyyppisiå puristuselimiå.In the figures, a 6-angle gluing wheel is marked with the reference number 1. The gluing wheel 1 can be rotated about a horizontal axis • · 92026 3 and its length corresponds mainly to the length of the gluing beam to be manufactured. Each ul-corner of the 6-angle gluing bath 1 has a triangular cross-sectional fixed stop 5 and 6. The glued preform 2 is intended to fit a compression die 3 bounded by a fixed stop 5 and a movable stop 7. Between the movable stop 7 and the second fixed stop 6 is provided with a hose, for example a fire hose 4, with which the compression pressure is provided using compressed air or pressurized water. In addition to hose 4, other 10 types of compression members can also be used.
Keksinn6n mukaisen liimauspuristimen toimintaa kuvataan lå-hemmin seuraavassa.The operation of the gluing press according to the invention is described in more detail below.
15 Liimauspyorån 1 kidan 3 tyhjennys ja tåytto jårjestetåån liimauspydrån ala-asennossa olevasta kidasta 3 ja kitaan 3 yhden tai kahden saksilavan 9 påålle asetetun, låhes kitavå-lin levyisen kuljetushihnan 8 avulla. Tåmån hihnan 8 lii-mauspy6rån 1 etupuolella oleva osa muodostaa liimoitus- ja 20 ladonta-aseman (ei esitetty kuviossa) ja liimauspyorån 1 alla oleva osa tyhjennys- ja tåyttoosan.The emptying and filling of the grid 3 of the gluing wheel 1 is arranged from the grid 3 in the lower position of the gluing ladder and the groove 3 by means of a conveyor belt 8 of almost one groove width placed on top of one or two scissor blades 9. The part of this belt 8 in front of the gluing wheel 1 forms a gluing and stacking station (not shown in the figure) and the part below the gluing wheel 1 forms a emptying and filling part.
Kun aihioiden liimauksessa kåytetåån PVAC-tyyppistå liimaa, se tarvitsee noin 5 minuutin puristusajan. Kun liimauspyorån 25 1 kidassa 3 asemassa 6. oleva aihiopinkka 2 on liimautunut, .. laskeutuu aseman 1 kohdalla oleva saksilava 9 sen verran, ettå liimauspyorå voi pydråhtåå 60°, jonka pySråhdyksen jål-keen saksilava 9 nousee takaisin ylåasentoon vastaanottamaan liimautuneen aihiopinkan.2, kun kita 3 avautuu. Kitavåli voi 30 esimerkiksi olla noin 600 mm. Tåmån jålkeen saksilava 9 laskeutuu ala-asentoonsa. Hihna 8 kåynnistyy sydttåen liimautuneen aihiopinkan ulos liimauspyfirån 1 alta samalla tuoden uuden aihiopinkan liimauspy6rån 1 alle, avautuneen kidan 3 , kohdalle. Saksilava 9 nostaa liimoitetun pinkan kitaan 3, 35 joka sulkeutuu saksilavan 9 eståesså nurjahduksen seuraavan noin 50 sekunnin ajan, minkå jålkeen se laskeutuu ja nåin toistuu edellinen liikesarja, jolloin koko kierroksen tehnyt aihiopinkka tulee olleeksi puristuksessa 6 x 50 s = 300 s 4 92026 = 5 min tai lyhyemmån/pitemmån ajan liiman ominaisuuksista riippuen. 3 m pitkien ja 200 mm leveiden aihioiden liimauk-sessa on saavutettavissa 15 m3/8 tunnin påivå liimausteho.When a PVAC-type adhesive is used to glue the blanks, it requires a pressing time of about 5 minutes. When the blank stack 2 in the position 6 of the gluing wheel 25 1 is glued, the scissor platform 9 at the position 1 lowers to such an extent that the gluing wheel can rotate 60 °, after which the scissor platform 9 rises to the up position to receive the glue wheel. when other 3 opens. For example, the gap may be about 600 mm. The scissor platform 9 then lowers to its lower position. The belt 8 starts by sucking the glued blank out from under the gluing belt 1 while bringing a new blank under the gluing wheel 1, at the opened groove 3. The scissor platform 9 lifts the glued stack to the jaw 3, 35, which closes when the scissor platform 9 prevents buckling for the next about 50 seconds, after which it lowers and thus repeats the previous series of movements, min or shorter / longer depending on the properties of the adhesive. When gluing 3 m long and 200 mm wide blanks, a gluing capacity of 15 m3 / 8 hours per day can be achieved.
5 Nurjahduksen eston varmistamiseksi puristinkidat 3 voidaan varustaa niiden sisåpuolelle ja pituussuuntaan keskiviivalle asetettavilla tyhjd- eli imukupeilla tai -laatikoilla, jois-ta yksi on katkoviivoin piirretty kuvioon 1 ja merkitty vii-tenumerolla 10. Nåistå imukupeista tai -laatikoista 10 sak-10 silavaa 9 vasten ala-asennossaan olevat imukupit tai -laa- tikko kytkeytyvåt/kytkeytyy tyhjopumppuun juuri ennen saksi-lavan 9 laskeutumista ja kytkeytyvåt/kytkeytyy irti tåyden kierroksen tehneenå saksilavan noustessa vastaanottamaan liimautunutta aihiopinkkaa 2. Mainitut imuelimet 10 voivat 15 olla kytkettynå joko koko pydråhdyksen ajan tai irrota jo aikaisemmin, kun nurjahdusvaara on varmasti ohitettu.5 In order to prevent buckling, the press crystals 3 can be provided with empty or suction cups or boxes placed inside them and longitudinally on the center line, one of which is drawn in broken lines in Fig. 1 and indicated by reference number 10. Of these suction cups or boxes 10 the suction cups or box in their lower position engage / engage in the vacuum pump just before the descent of the scissor platform 9 and engage / disengage after a full revolution of the scissor platform ascending to receive the glued blank 2. Said suction members 10 may either be earlier, when the risk of buckling is certainly passed.
