Description
7961457-7 2 ment innefattar uppfinningen vidare ett förfarande som utmärker sig av att man tillför ett från en veckningsmaskin kommande veckat, ban- liknande filtermaterial till en mottagningsram, vilken är utförd som en matris för utskärning av de cirkelskivformiga filterelementen och uppvisar lämpligt över ramens bäryta fördelade cirkelrunda öppningar, att man inspänner den i den på detta sätt utförda mottagningsramen införda filterbanan mellan två 1 mottagningsramen anordnade rörliga mothållarorgan, att man därefter för mottagningsramen med filterbanan över ett skakbord, varvid den inspända, veckade filterbanan med sina veck injusterar sig enligt ett i förväg bestämt veckavstànd, att man efter denna injustering över den första veckbanytans veckkanter pà- spritsar klisterringar pá sådant sätt, att dessa kommer att ligga iinnanför ramens matrisöppningar, att man efter fullbordad pàspritsnin; av dessa klisterringar vrider mottagningsramen l80° för påspritsning , av ytterligare klisterringar på den andra veckbanytan, och att man efter påspritsningen av samtliga klisterringar skär ut cirkelskivfor- miga filterelement ur filtermaterialet medelst en med matrisöppning- arna samverkande hålkniv, varvid klisterringarna innanför skärlinjen på båda sidor låser veckkanterna vid varandra. 7961457-7 2 The invention further comprises a method which is distinguished by adding a pleated, web-folding similar filter material to a receiving frame, which is made as a matrix for cutting out the circular disc-shaped filter elements and has suitably distributed circular openings distributed over the bearing surface of the frame, that it is clamped in the receiving frame designed in this way inserted filter path between two movable arrangements received in the receiving frame holding means, that the receiving frame is then moved with the filter path over a shaking table, the clamped, pleated filter web with its folds adjust according to a predetermined folding distance, that one after this adjustment over the fold edges of the first crease surface on the spritz adhesive rings in such a way that these will lie inside the matrix openings of the frame, that after completion of the spraying; of these adhesive rings rotate the receiving frame 180 ° for spraying, of additional adhesive rings on the other fold surface, and that one after spraying on all the adhesive rings, cut out the circular disc filter elements from the filter material by means of one with a matrix opening cooperating perforated knife, the adhesive rings within the cutting line on both sides the folding edges lock together.
De med uppfinningen uppnådda fördelarna är särskilt att inga avståndshållarorgan som uppfyller veekfickorna erfordras, varför å =na sidan den till förfogande stående, aktiva filterytan ökas väsent- ligt över det vid kända filterelement eljest vanliga måttet och å andra sidan en mindre klistermassa för extra sammanhållning av de bredvid varandra liggande veckkanterna behövs. Dessutom garanteras emellertid även genom det uppfinningsmässiga utförandet av filter- elementet, nämligen genom att klisterringarna pàföres på båda sidor på filterytorna på ett lämpligt nära avstånd från den skärlinje som skall åstadkommas, att det veckade filtermaterialet vid utskärning- en av det cirkelformiga filterelementet, vid skärlinjen icke kan av böjas eller klämmas ut i sidled genom snittrycket, vilket betyder att ett felfritt eirkelformigt filterelement föreligger efter skärningen.The advantages achieved by the invention are in particular that none spacer means that meet the wick pockets are required, why å = the side of the available active filter surface is significantly increased above the otherwise standard measure of known filter elements and å on the other hand a smaller adhesive mass for extra cohesion of the adjacent folding edges are needed. In addition, guaranteed however, also by the inventive embodiment of the filter the element, namely by applying the adhesive rings on both sides on the filter surfaces at a suitably close distance from the cutting line which it must be ensured that the pleated filter material at the cut-out one of the circular filter element, at the cutting line can not off bent or squeezed laterally by the sectional pressure, which means that a flawless non-circular filter element is present after cutting.
Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritning, på vilken fig. 1 visar en schematisk framställning av ett filterelement enligt föreliggande uppfinning, fig. 2 visar en planvy av filterelementet i fig. 1, fig. 3 visar en perspektivvy av en veckad filterbana i en mottagningsram, fig. 4 visar en perspektiv- vy av en del av mottagningsramen, varvid filterbanan för pàspritsning av klisterringar på en första filterbanyta är inspänd mellan två mot- 1991457-1 3 hållarorgan, fig. 5 visar en perspektivvy enligt fig. Ä, varvid mot- tagningsramen för påspritsning av ytterligare klisterringar på den andra filterbanytan är vriden l80°, fig. 6 visar en perspektivvy enligt fiß- 5, varvid en hålkniv skär ut cirkelskivformiga filter- element ur filterbanan.The invention is described in more detail below with reference to attached drawing, in which Fig. 1 shows a schematic representation of a filter element according to the present invention, Fig. 2 shows a plan view of the filter element in Fig. 1, Fig. 3 shows a perspective view of a pleated filter web in a receiving frame, Fig. 4 shows a perspective view of a part of the receiving frame, the filter path for spraying of adhesive rings on a first filter web surface is clamped between two 1991457-1 3 holding means, Fig. 5 shows a perspective view according to Fig. Ä, wherein the the mounting frame for spraying additional adhesive rings on it the second filter surface is rotated 180 °, Fig. 6 shows a perspective view according to fiß- 5, wherein a hollow knife cuts out circular disc-shaped filter elements from the filter path.
Såsom framgår av fig. 1 och 2, består det cirkelskivformiga filterelementet l i huvudsak av veckat filtermaterial, på vilket på över- och undersidan i närheten av ytterkonturen la är anordnade runt- om förlöpande klisterringar 2, vilka ingår i grundlig förening med veckkanten lb.As shown in Figs. 1 and 2, it consists of a circular disc the filter element 1 is mainly made of pleated filter material, on which on the upper and lower sides in the vicinity of the outer contour 1a are arranged round on continuous adhesive rings 2, which are included in thorough association with veckkanten lb.
Fig. 3 visar en veckad filterbana 3, som i pilens A riktning kommer från en icke visad veckningsmaskin, och löper in i en U-formig mottagningsram 4. Mottagningsramen 4 har två rörliga mothàllarorgan 5, mellan vilka filterhanan 3 inspännes i mottagningsramen. Mottag- ningsramen själv uppvisar ett antal cirkelrunda, över dess bäryta 4a fördelade öppningar Mb med motsvarande ytterkontur som filterele- menten l som skall framställas.Fig. 3 shows a pleated filter path 3, as in the direction of the arrow A. comes from a folding machine (not shown), and runs into a U-shaped receiving frame 4. The receiving frame 4 has two movable receiving means 5, between which the filter tap 3 is clamped in the receiving frame. Reception the frame itself has a number of circles, over its bearing surface 4a distributed openings Mb with the corresponding outer contour as filter elements l to be produced.
Fig. 4 visar hur man medelst en spritsanordning 6 påspritsar klisterringar på den första filterbanytan, medan fig. 5 visar mot- tagningsramen 4 med inspänd filterbana 3 =riden 1800 vid pàspritsning av den andra klisterringen på den andra filterbanytan, närmare bestämt den exakt mittemot den första klisterringen liggande klisterringen.Fig. 4 shows how to spray by means of a spray device 6 adhesive rings on the first filter web surface, while Fig. 5 shows the the shooting frame 4 with clamped filter path 3 = ridden 1800 when sprayed on of the second adhesive ring on the second filter web surface, more specifically the adhesive ring located exactly opposite the first adhesive ring.
Klisterringarna 2 utgöres av en tunn klistertràd za, som fungerar som en slags häfttråd.The adhesive rings 2 consist of a thin adhesive thread za, which acts as a kind of staple thread.
Spritsanordningen 6 löper i överensstämmelse med den klister- ring som skall påspritsas cirkelbanformigt över respektive filterban- yta och lägger klistertrâden 2a så på veckkanten lb, att klister- tråden icke tränger in i filterelementets 1 veckfickor la och sätter igenom dessa (fig. l och 2). För att kunna uppnå detta, måste sprits- anordningens 6 cirkelbanhastighet väljas i överensstämmelse därmed.The spraying device 6 runs in accordance with the adhesive ring to be sprayed circularly over the respective filter surface and lays the adhesive thread 2a so on the folding edge 1b that the adhesive the wire does not penetrate into the filter element 1 of the filter element 1a and inserts through these (Figs. 1 and 2). In order to achieve this, alcohol the circular path speed of the device 6 is selected accordingly.
Efter det att bägge sidor av filterbanytan blivit pàförda cirkelringar, placeras en roterande hålkniv 7 ovanför klisterringar- na, och utskäres ett cirkelskivformigt filterelement l i samverkan med matrisöppningarna 4b ur den veckade filterbanan.
