Abstract
Description
Sinfärbverfahren für hunststoffe, die zu beliebigen Kunststoffartikeln verarbeitet werden Die Erfindung betrifft ein Einfärbverfahren für Kunststoffe, die unter Verwendung bekannter Kunststoff-Verarbeitungsmaschinen zu beliebigen Kunststoffartikeln verarbeitet werden, Bei der Kunststoff-Verarbeitung werden das Einfärben und das Plastifizieren allgemein als zwei voneinander getrennte Arbeitsvorgänge betrachtet und daher auch es unabhängig voneinander mit besonderen Einrichtungen durchgeführt.Coloring process for plastics, resulting in any plastic article processed The invention relates to a coloring process for plastics, using known plastic processing machines to produce any plastic items When processing plastics, the coloring and the Plasticizing is generally viewed as two separate operations and therefore it also carried out independently of one another with special facilities.
Das Einfärben umfaßt dabei im wesentlichen Dosier- und Mischvorgänge, die mit bestimmten Maßnahmen zur Bevorratung des Mischgutes verbunden sind. Das Plastifizieren besteht im Einziehen und Verarbeiten des Mischgutes0 Diese Arbeitsweise hat den Nachteil, daß besondere Einrichtungen zum Mischen und für die Bevorratung und Zufuhr des Iviiischgutes in die Plastifizier-Einrichtung benötigt werden, die zu-dem vor einem Übergang auf einen anderen Farbstoff in zeitraubender Weise gereinigt werden müssen, Der Erfindung liegt die Aufgabe zugrunde, ein Einfärbverfahren für den eingangs erwähnten Zweck vorzuschlagen, bei dem gesonderte Mischeinrichtungen und Maßnahmen zur Bevorratung des Mischgutes und seiner Zuführung in die Plastifizier-Einrichtung entbehrlich sind, so dae neben einer erheblichen apparativen Vereinfachung auch die zeitraubende Reinigungsarbeit entfällt0 Gelöst wird diese Aufgabe nach der Erfindung bei einem Einfärbverfahren der eingangs erwähnten Art dadurch, daß der Farbstoff ohne jede Vormischung undmittelbar und taktweise in die Plastifizier-Einrichtung einer taktweise arbeitenden Kunststoff-Verarbeitungsinaschine eingeleitet wird, so daß innerhalb j jedes MIlaschinentaktes (Zyklus) eine Barbstoffzugabe erfolgt, Es hat sich gezeigt, daß es möglich ist, ohne getrennte Herstellung eines Farbstoffgemisches außerhalb der Kunststoff-Verarbeitungsmaschine im fertigen Kunststoffartikel eine Farbstoffverteilung zu erzielen, die diewenige sogar qualitativ übertrifft, die das Ergebnis herkömmlicher #is#hverfahren ist, Zweckmäßig ist die Steuerung der Dosiereinrichtung für die Farbstoffzugabe an die Steuerung der Kunst stoff-Verarbeitungsmaschine angeschlossen und erhält von dieser ihre Daktfolge.The coloring essentially comprises dosing and mixing processes, which are associated with certain measures to store the mix. That Plasticizing consists of drawing in and processing the mixed material0 This method of working has the disadvantage that special facilities for mixing and storage and supply of the Iviiischgutes are required in the plasticizing device also cleaned in a time-consuming manner before a transition to another dye Need to become, The invention is based on the object of a coloring process To propose for the purpose mentioned at the beginning, in the case of separate mixing devices and measures for storing the material to be mixed and feeding it into the plasticizing device are dispensable, so that in addition to a considerable simplification of the apparatus, there is also the time-consuming cleaning work is eliminated. This object is achieved according to the invention in a coloring process of the type mentioned at the outset in that the dye without any premixing and directly and intermittently in the plasticizing device an intermittent plastic processing machine is introduced, so that dye is added within j of each machine cycle, It has been shown that it is possible without a separate preparation of a dye mixture outside of the plastic processing machine in the finished plastic article a To achieve dye distribution that even qualitatively surpasses the few the result of conventional # is # h methods, the control of the Dosing device for adding dye to the control of the plastic processing machine connected and receives their Dacts from this.
Ein besonderer Vorteil ist erzielbar, wenn durch ein zwischen die Steuerangen der Dosiereinrichtung für die Barbstoffzugabe und der Kunststoff-Verarbeitungsmaschine eingeschaltetes Vorwahlzählwerk die Farbstoffzugabe in mehrere, über die Plastifizierdauer der Kunststoff - Verarbeitungsmaschine verteilte Teilmengen-Zugaben aufgeteilt wird0 Bei dem beschriebenen Einfwrbverfahren werden somit die Farbstoffe unmittelbar und taktweise in die Plastifiziereinrichtung eingeführt, so daß vor dem Übergang auf einen anderen Farbstoff nur letztere gereinigt zu werden braucht. G#esonderte Misch-, Vorrats- und Zufuhreinrichtungen für die getrennte Herstellung eines Mischgutes entfallen völlig.A particular advantage can be achieved if by a between the Control rods of the dosing device for the addition of dye and the plastics processing machine If the preset counter is switched on, the dye can be added in several steps over the plasticizing time plastic - Processing machine distributed partial additions is divided 0 In the described dyeing process, the dyes Immediately and intermittently introduced into the plasticizing device, so that before the transition to another dye only the latter needs to be cleaned. Separate mixing, storage and supply devices for separate production of a mixed material are completely eliminated.
