Werkwijze voor het beiei den van vellen met veelkleurige repen van thermoplastmaterialen.Method for providing sheets with multicolored strips of thermoplastic materials.
De onderhavige uitvinding heeft betrekking op een werkwijze voor het bereiden van vellen met veelkleurige repen van thermoplastmaterialen, die op zich een reeks zeer belangrijke voordelen biedt ten opzichte van de modernste 5 techniken die op het ogenblik in gebruik zijn en zijn ontwikkeld op dat industriële gebied.The present invention relates to a method of preparing sheets with multicolored strips of thermoplastic materials, which in itself offers a series of very important advantages over the most modern techniques currently in use and developed in that industrial field.
In de huidige praktijk bestaat een werkwijze of proces, verklaard in de Franse octrooiaanvrage 8515621, welke een bepaalde werkwijze definieert voor het verkrijgen 10 van versierde vellen, die bepaalde problemen hebben bij de praktische verwerkelijking daarvan tengevolge van de kruip van sommige lagen van kunststof samen met andere, hetgeen tot gevolg heeft de migratie van repen boven op andere wanneer verschillende kleuren van repen worden gebruikt.In current practice, a method or process, disclosed in French Patent Application 8515621, defines a particular method of obtaining decorated sheets, which has certain difficulties in its practical realization due to the creep of some layers of plastic together with others, resulting in the migration of bars on top of others when different colors of bars are used.
15 Daarom is het doel van de onderhavige uitvinding de bereiding van onder invloed van warmte geconformeerde vellen met een grote zekerheid en kwaliteit van bereiding, ondanks het feit dat het variëren van de omstandigheden van het extruderen of thermoconformeren op geen enkele manier 20 kritisch is, zoals wel het geval is bij andere toegepaste werkwi j zen.Therefore, the object of the present invention is to prepare heat-conforming sheets with a high degree of certainty and production quality, despite the fact that varying the extruding or thermoconforming conditions is not critical in any way, such as this is the case with other applied methods.
Het verkregen gerede produkt bestaat uit een kunststoflaag waar bovenop gelegen aanwezig zijn in de lengterichting lopende banden van onderscheiden breedte 25 waarop een bovenlaag van doorschijnende en glanzende kunststof is gelegen.The finished product obtained consists of a plastic layer on top of which there are present longitudinal conveyor belts of different width on which a top layer of translucent and glossy plastic is situated.
De fasen, van de werkwijze die het doel is van de uitvinding zijn de volgende:The stages of the method which is the object of the invention are the following:
In de eerste plaatst wordt het smelten en extru-30 deren van het thermoplastmateriaal in evenveel extrudeerinrichtingen als onderscheiden typen en kleuren van kunststof worden gebruikt, uitgevoerd, dat wil zeggen, als een basislaag, zes tussenliggende lagen van kleuren en een bovenste laag van doorschijnende kunststof worden genomen, moeten 35 acht extrudeermachines worden geplaatst, dat wil zeggen één voor elk type gebruikte kunststof. De kunststof die het gangbaarst wordt gebruikt tengevolge van zijn kwaliteiten 8702162 ï -2- / 4 en kenmerken zal het polystyreen zijn, omdat dit, wat de vorm heeft van grondstof, de fundamentele kenmerken voor de configuratie en kleuring ervan zal hebben.First, the melting and extruding of the thermoplastic material in as many extruders as different types and colors of plastic are used is performed, that is, as a base layer, six intermediate layers of colors and a top layer of translucent plastic eight extruders must be installed, ie one for each type of plastic used. The plastic most commonly used due to its grades 8702162 -2- / 4 and characteristics will be the polystyrene, because it, having the form of raw material, will have the basic characteristics for its configuration and coloring.
Dit kunststofmateriaal verkrijgt zijn weekheid 5 vanaf 90° of 100°C waarbij het zal beginnen te vervormen, teneinde de temperatuur ervan te verhogen tot een konstant niveau in die werkwijze van bij benadering 210°C, waarbij zij varieert tussen grenzen van 190° tot 300° in de vornier kop van die vellen.This plastic material acquires its plasticity from 90 ° or 100 ° C where it will begin to deform to raise its temperature to a constant level in that process of approximately 210 ° C, varying between limits of 190 ° to 300 ° in the front of those sheets.
10 Al deze gesmolten kunststofmaterialen komen uit de extrudeerinrichtingen, bereiken een eerste plaat, die daarbij een verdeling aanbrengt door afzonderlijke horizontale kanalen, die elk drager zijn van één van de kunststofmaterialen. Uit deze plaat wordt een andere verdeler, 15 die door middel van de vereiste ligging in de geconformeerde van van de ene en de andere kleur verdeeld over die hoogte via een leiding die de gewenste kleur in het middelpunt stelt teneinde uiteindelijk een centrale plaatsing van gewenste kleuren te bereiken, die extraheerbaar zijn door 20 middel van de overeenkomstige leidingen ervan. Voor de conformering in banden zijn deze dragende leidingen van de onderscheiden kleuren zodanig gemaakt dat zij een stuk bereiken in een kamvorm waarin het kunststofmateriaal stroomt door de driehoekige gedeelten ervan vanaf de top naar het 25 uitgangsgedeelte waarin het tegelijkertijd wordt verenigd met de andere zijbanden. Tegelijkertijd wordt het basismateriaal en de bovenliggende doorschijnende kunststof, verdeeld door respektievelijk de onderste en bovenste kanalen, voorwat betreft de eerste van hen gestuurd door de 30 onderste zone van de kop en de tweede door het bovenste gedeelte tot het enige punt van vereniging met de tussenliggende kleurbanden, terwijl alle zijn verenigd in dezelfde zone waarmee ondanks het bezit van onderscheiden vloeibaarheden, fysische eigenschappen of drukken, genoemde kenmerken 35 in evenwicht worden gehouden, waarbij geen afwijkingen, migraties van de ene naar de andere band optreden, noch vanaf de ene laag naar de andere tengevolge van de vereniging van alle in hetzelfde punt van de kop.All these molten plastic materials come from the extruders, reach a first plate, which thereby distributes them by separate horizontal channels, each of which is carrier of one of the plastic materials. From this plate another divider, which by means of the required location in the conformed van of one color and the other, is distributed over that height via a pipe which focuses on the desired color in order to ultimately have a central placement of desired colors. which are extractable by means of their corresponding conduits. For tire conformation, these carrier lines of the distinct colors are made to reach a piece in a comb shape in which the plastic material flows through its triangular portions from the top to the exit portion in which it is simultaneously joined with the other side bands. At the same time, the base material and the upper translucent plastic, divided by the lower and upper channels, respectively, as far as the first of them is directed through the lower zone of the head and the second through the upper part to the only point of union with the intermediate color bands, while all are united in the same zone with which, despite possessing distinct fluids, physical properties or pressures, the said characteristics are balanced, with no deviations, migrations from one band to another, nor from one layer to the other due to the union of all in the same point of the heading.
De dikte van de banden wordt gereguleerd doordat 40 de stroom van kunststof zich uitstrekt naar de kop, waardoor 8702162 -3- een kleine stroom verplicht tot de vorming van een fijne band en een bovenste stroom tot een dikkere band.The thickness of the straps is regulated by the flow of plastic extending to the head, whereby a small stream obliges 8702162-3 to form a fine band and an upper stream to form a thicker band.
De rechtvaardiging van die variatie van dikte van de tussenliggende kleurband is toe te schrijven aan het feit, 5 dat wanneer de vaten die uit die plaat komen, conformeren, als een band van geringe dikte wordt gebruikt in een sterke kleur het gevoel van zwakheid zal worden gegeven omdat de inhoud van het inwendige ervan, omdat de steunlaag wit is, doorschijnend zou worden tengevolge van deze geringe dikte van 10 de kleurband, waardoor in de sterke kleuren een dikte van de tussengelegen kleurband gewoonlijk iets groter is dan in zwakke kleuren.The justification for that variation of thickness of the intermediate color band is due to the fact that when the barrels emerging from that plate conform, if a band of low thickness is used in a strong color the sense of weakness will become given that the contents of its interior, because the backing layer is white, would become translucent due to this small thickness of the color band, whereby in the strong colors a thickness of the intermediate color band is usually slightly greater than in weak colors.
De breedte van de banden worden gereguleerd door het stuk in de vorm van driehoekige kammen waarin afhankelijk 15 van de breedte ervan of het gedeelte van de uiteindelijke opbrengst, de omvang van het vel in banden min of meer breed wordt uitgevoerd.The width of the tapes is regulated by the piece in the form of triangular ridges in which, depending on its width or the portion of the final yield, the size of the sheet in tapes is made more or less wide.
Het onder invloed van warmte geconformeerde vel wordt in totale dikte gereguleerd in de afvoer ervan door middel 20 van de vervorming van de afvoerlip van het matrixstuk of conformatiespindop; door middel van een insnoering in de dikte van de afvoer ervan zal de eenmaal tot stand gebrachte band een totale breedte hebben die wordt begrensd door de gebruikte spindop, waarbij de grootte is vastgelegd voor 25 elke spindop terwijl de totale dikte van het vel zou kunnen variëren tussen 0,6 en 2,4 mm, waarbij de verhouding van de configuratie-elementen qua dikte wordt gegeven in percentages van; - 3,5 tot 6% in de bovenste laag, doorschijnend en 30 glanzend, 40 tot 60% van dikte in de kleurbanden, en - 56,5 tot 34% in dikte van het basismateriaal.The heat conformed sheet is controlled in total thickness in its discharge by deformation of the discharge lip of the matrix piece or conformation spinneret; by constricting the thickness of its drain, the tape once created will have an overall width limited by the spinneret used, the size being fixed for each spinneret while the total thickness of the sheet could vary between 0.6 and 2.4 mm, the ratio of the configuration elements in terms of thickness being given in percentages of; - 3.5 to 6% in the top layer, translucent and 30 glossy, 40 to 60% in thickness in the color bands, and - 56.5 to 34% in thickness of the base material.
De snelheid van vorming van die vellen is bij voorkeur 7-11 meter per minuut, waarbij een configuratie van die vel-35 len in een stabiele en juiste vorm deze waarden weergeven, terwijl deze afvoersnelheid wordt verkregen door middel van de aanpassing van de extrudeerinrichtingen die zodanig zijn dat zij de stuwing van het kunststofmateriaal in de configuratie ervan te weeg brengen.The speed of formation of those sheets is preferably 7-11 meters per minute, with a configuration of those sheets in a stable and correct shape representing these values, while this discharge speed is obtained through the adjustment of the extruders which be such as to effect the propulsion of the plastic material in its configuration.
40 Bij de afvoer van de kop of configureringsspindop 8702162 * -4- wordt het vel geleid door koelwalsen, die op een kon-stante temperatuur worden gehouden door een inwendige koeling door water ervan, teneinde naar het einde ervan te gaan, om te worden verzameld voor opspoelen in cilindrische 5 windingen.40 At the discharge of the head or configuration spinneret 8702162 * -4-, the sheet is passed through cooling rollers, which are kept at a constant temperature by an internal cooling by water thereof, to go to the end of it, to be collected for winding in cylindrical 5 turns.
Als eindbewerking van genoemde werkwijze wordt het overlangs in repen snijden uitgevoerd door middel van een in repensnijder die de bijzonderheid heeft dat hij de scheiding van kleuren detecteert door middel van toepassing 10 van foto-elektrische cellen die de in repensnijder besturen.As a final operation of said method, the longitudinal cutting is performed by means of a strip cutter which has the special feature of detecting color separation by using photoelectric cells controlling the strip cutter.
Anderzijds kan de breedte van de banden die de vellen hebben, variëren tussen 3 en 600 mm, waarbij die variatie ontstaat door de configuratie van het stuk in de tussenliggende kamvorm.On the other hand, the width of the belts the sheets have can vary between 3 and 600 mm, the variation being due to the configuration of the piece in the intermediate comb shape.
