Description
Foreliggende oppfinnelse vedrører en fremgangsmåte ved rebondstøping hvori revet skum med lim føres inn i en støpeform samt en støpeform for rebondstøping av skumbiter. The present invention relates to a method for rebond molding in which torn foam with glue is fed into a mold and a mold for rebond molding of foam pieces.
Bakgrunn for oppfinnelsen Background for the invention
I produksjon av møbler benyttes ofte skumprodukter slik som polyuretan (PU) til polstring av møbeldelene, enten uteluk-ket eller i kombinasjon med andre materialer eller komfort-givende deler slik som fjærer. Under bearbeidelse av skum etter støpingen blir det en del avskjær av skum, slik som fra renskjæring, men også etter tilskjæring av skum til diverse møbeldeler. In the production of furniture, foam products such as polyurethane (PU) are often used for padding the furniture parts, either alone or in combination with other materials or comfort-providing parts such as springs. During the processing of foam after casting, there is some off-cut of foam, such as from clean cutting, but also after cutting foam for various furniture parts.
Avskjæret samles og kuttes opp i små biter som senere kan brukes som fyllstoff eller også blandes med lim for å støpes til egne enheter, slik som for eksempel madrasser og puter. Denne metoden kalles "rebond" ettersom den binder sammen avskjærsbiter av støpt skum. For å lime polyuretan benyttes for eksempel prepolymer av polyol og isocyanat. The scrap is collected and cut into small pieces that can later be used as filler or mixed with glue to be molded into separate units, such as mattresses and pillows. This method is called "rebond" as it binds together scrap pieces of molded foam. To glue polyurethane, for example, prepolymer of polyol and isocyanate is used.
Ulempen med metoden er at tettheten av produktene som frem-stilles på denne måten generelt blir relativt lav og ujevn, noe som gjøre at skumproduktet blir relativt mykt og lett faller fra hverandre. Rebondmetoden benyttes derfor fortrinnsvis til produkter som ikke utsettes for stor slitasje av kanter, og/eller produkter som har en enkel form slik som madrasser. The disadvantage of the method is that the density of the products produced in this way is generally relatively low and uneven, which means that the foam product becomes relatively soft and easily falls apart. The Rebond method is therefore preferably used for products that are not exposed to a lot of edge wear, and/or products that have a simple shape such as mattresses.
Imidlertid er den ujevne hardheten av rebondprodukter heller ikke spesielt egnet for madrasser der det stadig stilles høyere krav til komfort og kontroll av mykhetsgrad. However, the uneven hardness of rebond products is not particularly suitable for mattresses where there are increasingly high demands on comfort and control of the degree of softness.
Det er således et behov for andre måter å benytte restskum fra annen skumproduktproduksjon, samt å forbedre rebondmetoden . There is thus a need for other ways of using residual foam from other foam product production, as well as to improve the rebond method.

Detaljert beskrivelse Detailed description
Foreliggende oppfinnelse vil nå bli beskrevet ved en utfør-elsesmåte som ikke begrenser omfanget av oppfinnelsen, som er definert i de vedlagte patentkravene. The present invention will now be described in an embodiment which does not limit the scope of the invention, which is defined in the attached patent claims.
I denne utførelsen produseres en pute, slik som til en skammel eller stol/sofapute. In this version, a cushion is produced, such as for a stool or chair/sofa cushion.
Som nevnt benytter foreliggende fremgangsmåte rester av skum fra øvrig produksjon av skumprodukter enten internt i en produksjon, eller skumrester kan kjøpes fra andre prod-usenter. Fremgangmåten er således miljøvennlig ved at den utnytter avfall eller kan resirkulere skum, slik som poly-uretanskum. As mentioned, the present method uses leftover foam from other production of foam products either internally in a production, or leftover foam can be bought from other production centers. The method is thus environmentally friendly in that it utilizes waste or can recycle foam, such as polyurethane foam.
For å benytte rester av ujevn størrelse rives skummet opp i en granulator, for derved å gi skumbiter av noenlunde samme størrelse. Skumbitene lagres på store oppbevaringstanker og kan mates eller doseres ved en skruemater i bunnen av en slik tank. Ved å skru skumbitene ut i et blanderom med til-førsel av trykkluft kan bitene fluidiseres og transporteres til støpeformen gjennom rørganger. In order to use residues of uneven size, the foam is torn up in a granulator, thereby giving pieces of foam of approximately the same size. The pieces of foam are stored in large storage tanks and can be fed or dosed by a screw feeder at the bottom of such a tank. By screwing the pieces of foam out into a mixing room with a supply of compressed air, the pieces can be fluidized and transported to the mold through ducts.
Fortrinnsvis blandes det inn ca. 10% lim med skumbitene før de blåses eller suges inn i støpeformen. Limet kan sprayes inn i den fluidiserte blandingen og kan være et varmeherd-ende lim. Preferably mix in approx. 10% glue with the foam pieces before they are blown or sucked into the mold. The adhesive can be sprayed into the fluidized mixture and can be a thermosetting adhesive.
Ettersom skumbitene fluidiseres og transporteres med luft kan fyllingen av støpeboksen utføres på særdeles kort tid sammenlignet med tradisjonell støping. I dette eksemplet fylles støpeboksen 1 i fig. 1 på under 1 sekund. As the pieces of foam are fluidized and transported with air, the filling of the molding box can be carried out in an extremely short time compared to traditional molding. In this example, the casting box 1 in fig. 1 in under 1 second.
Deretter lukkes kassen og ristes eller vibreres i omtrent 2 sekunder som er tilstrekkelig for å få en jevnere fordeling og/eller pakking av skumbitene og derved også et tettere og fastere produkt. I dette eksempelet er støpekassen 1 i fig. 2 montert på en dreibar flate 20, og en bevegelig leddet arm 21 koblet til et svinghjul 22 rister eller vibrerer kassen 1 når svinghjulet 22 dreies. The box is then closed and shaken or vibrated for approximately 2 seconds, which is sufficient to obtain a more even distribution and/or packing of the foam pieces and thereby also a denser and firmer product. In this example, the casting box 1 in fig. 2 mounted on a rotatable surface 20, and a movable articulated arm 21 connected to a flywheel 22 shakes or vibrates the case 1 when the flywheel 22 is turned.
For å ytterligere øke tettheten av støpeproduktet reduseres deretter volumet av støpeformen for å presse sammen skumbitene, som etter risting eller vibrering ligger bedre pakket og har større kontaktflate og derved bedre potensial for sammenliming. I dette eksempelet er sidekantene 30 i den øvre delen 2 av støpeboksen 1 bevegelige og kan presses innover ved hjelp av stempler 31. For å få en kompakt pute er også bunnen av støpeboksen i dette eksempelet utstyrt med lignende anordninger. I dette eksemplet hever bunnen seg først for å posisjonere og presse skummassen opp i lokkdelen av støpeboksen og deretter presses sidekantene 30 av lokket inn for å få en ekstra høy tetthet i sidekantene på produktet. In order to further increase the density of the cast product, the volume of the mold is then reduced in order to press together the foam pieces, which after shaking or vibrating are better packed and have a larger contact surface and thereby better potential for bonding. In this example, the side edges 30 in the upper part 2 of the mold box 1 are movable and can be pressed inward by means of pistons 31. In order to obtain a compact cushion, the bottom of the mold box in this example is also equipped with similar devices. In this example, the bottom first rises to position and press the foam mass up into the lid part of the mold box and then the side edges 30 of the lid are pressed in to get an extra high density in the side edges of the product.
Etter at volumet i støpeformen er redusert, tilføres damp inn i kassen i ca. 3 sekunder, og skumbitene limes og herdes øyeblikkelig. After the volume in the mold has been reduced, steam is fed into the box for approx. 3 seconds, and the foam pieces are glued and cured instantly.
Deretter kan støpeformen 1 åpnes og produktet 10 fjernes for støping av neste eksemplar. The mold 1 can then be opened and the product 10 removed for casting the next specimen.
En slik prosess tar omtrent 5-10 sekunder å gjennomføre sammenlignet med omtrent 5 minutter tradisjonell støping med flytende skum som ekspanderes og herdes. Such a process takes about 5-10 seconds to complete compared to about 5 minutes of traditional molding with liquid foam that expands and hardens.
I tillegg er fremgangsmåten av foreliggende oppfinnelse spesielt egnet til å støpe inn deler i skummet. I fig. 4 er det vist en kjernedel 40 av hard plast som skal støpes inn i puten. Ved å plassere kjernedelen 40 i støpeformen 1 slik at det er åpninger 42 rundt kjernedelen eller hull 43 i kjernedelen 40 vil skumbitene blåses rundt kjernen 40 og omhylle denne. På denne måten kan kjernedelen enkelt støpes inn i en polstring. Dette er mye raskere og enklere enn å innstøpe kjernedelen ved å benytte flytende ekspanderende skum, eller å produsere to skumdeler som må limes rundt kjernen i etterkant. In addition, the method of the present invention is particularly suitable for molding parts into the foam. In fig. 4 shows a core part 40 of hard plastic which is to be molded into the cushion. By placing the core part 40 in the mold 1 so that there are openings 42 around the core part or holes 43 in the core part 40, the pieces of foam will be blown around the core 40 and envelop it. In this way, the core part can be easily molded into a padding. This is much faster and easier than embedding the core part using liquid expanding foam, or producing two foam parts that must be glued around the core afterwards.
Foreliggende oppfinnelse vedrører derfor også en støpeform for anvendelse i rebondstøping der én eller flere sider av formen kan skyves inn i formen for å sammenpresse skumbiter. Støpeformen har ett innløp for skumbitene eller et lokk slik at skumbiter kan fylles i formen, samt et innløp for damp for å herde limet som binder skumbitene sammen. The present invention therefore also relates to a mold for use in rebond molding where one or more sides of the mold can be pushed into the mold to compress pieces of foam. The mold has one inlet for the foam pieces or a lid so that foam pieces can be filled into the mold, as well as an inlet for steam to harden the glue that binds the foam pieces together.
Fortrinnsvis har støpeformen en riste- eller vibreringsanordning for å pakke skumbitene sammen før herding og eventuelt har støpeformen holde- eller støttepunkter for å plassere en kjerne, slik som en kjerne av hard plast, for fullstendig eller delvis innstøping i skumproduktet. Preferably the mold has a shaking or vibrating device to pack the foam pieces together before curing and optionally the mold has holding or support points for placing a core, such as a hard plastic core, for full or partial embedding in the foam product.

Fremgangmåten og apparatet ifølge oppfinnelsen kan selv-følgelig benyttes til alle typer skum som kan limes på tilsvarende måter. Videre er det forutsett at en rekke additiver kan være innblandet i skumbitene på forhånd eller tilsettes til skumblandingen som går inn i støpeformen. Slike additiver kan være farge, varmereaktive midler (f.eks. lim, bindemidler og herdere), eller brannhemmende midler slik som grafitt. The method and apparatus according to the invention can of course be used for all types of foam that can be glued in similar ways. Furthermore, it is assumed that a number of additives can be mixed into the foam pieces in advance or added to the foam mixture that goes into the mold. Such additives can be colour, heat reactive agents (eg adhesives, binders and hardeners), or fire retardants such as graphite.
