Description
Verfahren und Vorrichtung zur automatischen Schnellvulkanisation von Gummipreßartikeln Die Erfindung bezieht sich auf ein Verfahren und aut Vorrichtungen zur automatishcen Schnellvulkanistation von Gummipßartikeln. Es ist bereits vorgeschlagen worden, die Vulkanisation von Gummipreßartikeln nicht mehr wie bisher in schweren, großen, hydraulisch betriebenen Pressen, sondern in automatischen Vorrichtungen vorzunehmen, die in Form eines Karussells oder nach Art eines Waffelbackautomaten ausgeführt waren. In diesen Automaten kamen hauptsächlich cinkalibrige Formen zur Verwendung, deren Eigenart darin besteht, daß bei ihnen mit verhältnismäßig geringem Druck gearbeitet wird. Dies war deshalb notwendig, weil bei den automatischen Maschinen nicht Iiolre Drücke angewendet werden können, zumal diese Maschinen nicht so schwer und massiv zu bauen sind.Method and device for the automatic rapid vulcanization of Rubber molded articles The invention relates to a method and devices for the automatic rapid vulcanization of rubber molded articles. It's already suggested been, the vulcanization of rubber molded articles no longer as before in heavy, large, hydraulically operated presses, but in automatic devices make that in the form of a carousel or in the manner of a waffle maker were executed. In these machines mainly cincaliber forms were used Use, the peculiarity of which is that with them with relatively little Pressure is being worked on. This was necessary because of the automatic machines Iiolre pressures cannot be applied, especially since these machines are not that heavy and are massive to build.
Diese Vorrichtungen haben sich jedoch bisher in der Technik nicht bewährt, weil die an Automaten zu stellenden hohen Leistungen wegen der großen Vulkanisationsdauer nicht erreicht werden konnten. So zeigte sich, daß bei einem zwölfteiligen Karussell und bei einer Gummimischung von 6 Minuten Vulkanisationsdauer die Vorrichtung in der Minute einen einzigen, höchstens jedoch I½ Gummipreßteile lieferte, was der Zahl von 90 Stück in der Stunde entspricht. However, these devices have heretofore not proven themselves in the art Tried and tested because of the high performance to be provided on machines because of the long duration of vulcanization could not be reached. So it turned out that with a twelve-part carousel and with a rubber mixture of 6 minutes vulcanization time the device in the minute delivered a single, but at most 1½ rubber molded parts, which the Number of 90 pieces per hour.
Erfindungsgemäß werden diese Nachteile vermieden und gleichzeitig eine sehr rationelle Arbeitsweise ermöglicht, indem die bisher bei Automaten verwendete thermoelektrische Widerstandsheizung, oder Dampfbeheizung durch eine Hochfrequenzbeheizung ersetzt wird. Die hierbei mögliche kurze Vulkanisationszeit gestattes es, einen Automaten mit denkbar vollkommener zeitliecher Ausnutzung zu betreilben. Bisher was die Langsamkeit der Arbeitsweise vov Vulkanisierpressen ein Hindernis für das Einführen der Hochfrequenzbeheizung. So hatte es keinen Zweck, eine hydraulische Presse mit einer Hochfrequenczbeheizung auszustatten und die Vulkanisationsdauer von 6 auf 0,6 Minnten herabzusetzen, wenn gleichzeitig die Zeit für die Beschickung der Presse nicht unter 2 Minuten gesekt werden konnte. Darüber hinaus waren die robust gebauten Pressen für den Einbau der mehr oder weinger diffizilen elektrischen Einrichtungen für die Hochfrequenzbcheizung ungeeignet. According to the invention, these disadvantages are avoided and at the same time allows a very efficient way of working by using the one previously used in machines thermoelectric resistance heating, or steam heating using high-frequency heating is replaced. The short vulcanization time possible here allow it is to operate an automaton with a conceivably perfect temporal utilization. So far, the slowness of the vulcanizing presses has been an obstacle for the introduction of high frequency heating. So there was no point in being a hydraulic one To equip the press with high frequency heating and the duration of vulcanization from 6 to 0.6 minutes, if at the same time the time for loading the press could not be sparkling for less than 2 minutes. In addition, they were robustly built presses for the installation of the more or less difficult electrical ones Equipment unsuitable for high-frequency heating.
Nach der Erfindung ist es erforderlich, die Vorrichtung der Eigenart der Hochfrequenzbeheizung anzupassen, was durch Herstellung aus drei Teilen erreicht wird. Der obere und untere Teil besteht aus Stahl und ist gegenüber dem karusselltisch elektrisch isoliert, während der mittlere Teil aus keramischem Werkstoff hergestellt ist und an einer der Stahplatten so befestigt ist, daß zwischen dieser stahlpatte und dem Keramikteil kein Zwischenraum frei bleibt, hin welchen beim Prcssen Kautschuk eindringen kann, der das Herausuelument des Preßartikels aus der Form erschwere würde. According to the invention it is necessary to use the device of the characteristic adapt to the high-frequency heating, which is achieved by manufacturing from three parts will. The upper and lower part is made of steel and is opposite the carousel table electrically isolated, while the middle part is made of ceramic material is and is attached to one of the steel plates so that between this steel plate and the ceramic part does not have a gap which, in the case of rubber, is pressed can penetrate, which make it difficult to remove the pressed article from the mold would.
Wegen der von innen heraus entstehenden Wärme als Eigentümlichkeit der Hochfrequenzbeheizung ist man in der Lage, einen Geringeren Druck bei der Vulkanisation zu verwenden, der nur so hoch zu sein brancht. als er eine Blasenbildung mit Sicherheit verhindert. Die Luft entweicht aus der Form biem erfindungsgemäßen Verfahren leichter, weil die Vulkanisation und damit Erhärtung des Gummis im Innern beginnt, während die äußeren Teile iiizwischen noch fließen, so daß die Luftblasen Gelegenheit haben , nach außen abzuwandern. die für die Aufnahme des Drucks bestimmten Teile der Karussell,konstruktion können daher ir'!. leichter als sonst gestaltet werden Xachdem der elektrische Strom selbsttätig abgeschaltet worden und damit die Vulkanisation beendet ist, wird der untere Formteil mit dem Keramikteil durch automatisch einsetzendes Ausfprühen von Wasser gekühlt, um das Herausnehmen zu erleichtern. Because of the warmth that arises from within as a peculiarity the high-frequency heating is able to use a lower pressure during vulcanization to use that branches just so high to be. when he was blistering for sure prevented. The air escapes from the mold more easily in the process according to the invention, because the vulcanization and thus hardening of the rubber begins inside while the outer parts still flow in between, so that the air bubbles have an opportunity to migrate to the outside world. the parts of the carousel intended to take the pressure, construction can therefore ir '!. After that, the electric current will be designed more easily than usual has been switched off automatically and thus the vulcanization has ended, the Lower molded part with the ceramic part by automatically spraying out Water chilled to make it easy to remove.
Dic obere Platte wird dagegen nicht gekühlt , damit das Preßteil an ihr beim herausnehmen zunächst haften bleibt. Im Gegensatz zu dem bisher verwendeten Vulkanisierverfahren ist diese Abkühlung nicht mit einr Verkürzung der darauffolgenden Vulkanisation verknüpft. Das Ablösen des Preßteils von der oberen Platte erfolgt numehr automatisch durch einen einfachen Schiebevorgang.The upper plate, however, is not cooled, so that the pressed part on it initially sticks when you take it out. In contrast to the one previously used In the vulcanization process, this cooling is not accompanied by a shortening of the subsequent one Vulcanization linked. The pressed part is detached from the top plate more automatically by a simple sliding process.
In der nächsten karsussellstellung erfolgt das Einspritzen der Form mit einer Formlösung aus Seife od. dgl. mit Hilfe einer Spritzpistole. Auch dieser Vorgang erfolgt vollautomatisch. Schließlich wird das einfüllen der Form in der letzten ofenenn Stellung des Karussels ebenfalls automatisch mit hilfe einer bekannten Schiebyorrichtung mittels einer Rinne erricht. Anschließend erfolgt die Vulkanisation durch selbsttätiges Eipschalten des Hochfrequenzstroms an isoliert angebrachten Vulkanisierplatten. In the next carousel position, the mold is injected with a mold solution of soap or the like with the aid of a spray gun. Also this one The process is fully automatic. Finally filling the mold in the last oven position of the carousel also automatically with the help of a known one Erect sliding device by means of a gutter. Vulcanization then takes place by automatically switching on the high-frequency current to insulated ones Vulcanizing plates.
Einen noch besseren technischen Erfolg erzielt man bei Vetwendung eines Gummis aus mit Latex versetztem vulkanisiertem Gummischleifmehl. Danach werden aus dem präparierten getrockneten Gummimehl in einem Durchlauf durch ein kombinertes Beschickungs- und Vulkanisierkarussell fertige Preßartikel hergestellt, ohne daß Stanzabfälle entstehen. Even better technical success can be achieved with use a rubber made of vulcanized rubber grinding powder mixed with latex. After that will be from the prepared dried rubber powder in one pass through a combined Charging and vulcanizing carousel produced finished pressed articles without Punching waste is generated.
Diese Bescbickungsvyorrichtung besteht aus einer in der Kunststoffindustrie verwendeten Dosier- und Komprimiervorrichtung. Durch diese Vorrichtung wird eine gleichbleibende, bestimmte Menge des Gummimehls durch einen hin und her gehenden Stempel in die gewünschte Form und Größe des fiir die Vulkanisierform benötigten Rohlings komprimiert.This loading device consists of one used in the plastics industry used dosing and compression device. This device is a constant, specific amount of rubber powder by moving it back and forth Stamp in the shape and size required for the vulcanization mold Compressed blank.
Damit der Rohling hesser zusammenhält. kann vorgewärmtes Gummimeill verwendet werden. Zur besseren Beförderung des gummimehls in den Dosierzylinder wird eine Rühr- und Zerkleinerungsvorrichtung für die Zerkleinetung der biem lagern sich bildenden lockeren Klumpen vorgeschaltet. Diese Vorrichtung arbeitet im gleichen Takt mit dem Vulkanisierkarussell und wird zweckmäßigerweise mit ihm gekoppelt. Die Rohlinge gelangen demnach völlig automatisch aus der Komprimiervorrichtung unmittelbar in die Vulkanisierform.So that the blank holds together hesser. can preheated rubber mill be used. For better conveyance of the rubber powder into the dosing cylinder will store a stirring and crushing device for crushing the biem upstream loose lumps that form. This device works in the same way Clock with the vulcanizing carousel and is expediently coupled with it. Accordingly, the blanks come out of the compression device directly and completely automatically into the vulcanizing mold.
