Description
Die Erfindung betrifft ein Verfahren zur Herstellung von technischen Objekten, hergestellt aus chemischen Substanzen, geeignet zur Erzeugung eines Grundmaterials wie z.B. einem geschäumten oder kompakten Duroplast, im Spritz- und/oder Gießverfahren, wobei der chemischen Rezeptur gezielt Additive zur Veränderung farblicher, chemischer und/oder physikalischer Eigenschaften in bestimmten Bereichen des technischen Objekts zugemischt werden. The invention relates to a process for the production of technical objects made of chemical substances suitable for producing a base material such as e.g. a foamed or compact thermosetting plastic, in the injection and / or casting process, wherein the chemical formulation targeted additives are added to change color, chemical and / or physical properties in certain areas of the technical object.
Darüber hinaus betrifft die Erfindung eine Vorrichtung zur Durchführung dieses Verfahrens. Moreover, the invention relates to a device for carrying out this method.
Obwohl die herzustellenden technischen Objekte hierauf nicht beschränkt sind, wird die Erfindung im Folgenden beispielhaft als Verfahren und Vorrichtung zur Herstellung von Schuhteilen, beispielsweise Sohlen, beschrieben. Although the technical objects to be produced are not limited thereto, the invention will be described below by way of example as a method and apparatus for producing shoe parts, for example soles.
Eine derartige Sohle ist heutzutage kein Gegenstand mehr, der als einfarbiges, in seinen Eigenschaften durchgängiges Objekt zu betrachten ist. Gerade aus optischen und modischen Gründen werden heutzutage verschiedenfarbige Sohlen gewünscht, wobei auch innerhalb einer Sohle verschiedene Farben vorgesehen sein sollen. Such a sole is nowadays no longer an object to be regarded as a monochrome object that is consistent in its properties. Especially for visual and fashionable reasons, nowadays different colored soles are desired, wherein also within a sole different colors should be provided.
Darüber hinaus sollen derartige Sohlen spezielle physikalische Eigenschaften aufweisen, was beispielsweise die Abrasion, die Rutschfestigkeit, oder die Beständigkeit gegen gewisse Chemikalien angeht. In addition, such soles should have special physical properties, such as abrasion, skid resistance, or resistance to certain chemicals.
Somit ist eine derartige Sohle, was den Herstellungsprozess angeht, heutzutage immer komplexer geworden. Das gilt natürlich auch für den apparativen Aufwand. So müssen verschiedene Rezepturen bestehend aus einem Grundmaterial und den entsprechenden Additiven mittels unterschiedlicher Aggregate in die Kavität einer Form eingefüllt werden. Oder aber es müssen komplizierte Einspritzdüsen eingesetzt werden, beispielsweise beim so genannten Sandwich-Molding. Thus, as far as the manufacturing process is concerned, such a sole has become more and more complex nowadays. Of course, this also applies to the expenditure on equipment. Thus, different formulations consisting of a base material and the corresponding additives must be filled by means of different aggregates in the cavity of a mold. Or else complicated injection nozzles have to be used, for example in so-called sandwich molding.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art so zu führen, dass mit einem Einfüll-Aggregat gearbeitet werden kann und die Spritzabfolge unterschiedlicher Rezepturen mittels einer intelligenten Steuerung erfolgt. The invention is therefore based on the object to perform a method of the type mentioned so that you can work with a filling unit and the injection sequence of different recipes by means of an intelligent control.
Die Erfindung löst diese Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1 dadurch, dass das herzustellende technische Objekt als Computermodell zunächst virtuell in Sektoren eingeteilt wird, jedem Sektor eine bestimmte Rezeptur aus Grundmaterial und Additiven zugeordnet wird, die einem Mischkopf softwaregesteuert über ein Ventilsystem nacheinander, Sektor für Sektor, zugeführt und dort vermischt wird und diese Mischungen nacheinander in einem Schuss software-gesteuert in eine Formkavität in einer Spritzgießmaschine dem jeweiligen Sektor entsprechend gefördert wird, in der sie aufschäumt und durch Schließen der Kavität in die gewünschte Form gepresst wird. The invention solves this problem according to the characterizing part of
Um beim Beispiel einer Schuhsohle zu bleiben, wird diese Schuhsohle beispielsweise in drei Sektoren eingeteilt, nämlich einen Absatzsektor, einen Mittelfußsektor und einen Fußspitzensektor. Dabei soll beispielsweise der Fußspitzensektor rot, der Mittelfußsektor gelb und der Absatzsektor schwarz ausgebildet werden. Über das Ventilsystem werden dann in der Reihenfolge des späteren Einfüllens die jeweiligen Sektorrezepturen aus Grundmaterial und entsprechenden Additiven nach und nach in den Mischkopf eingegeben, dort vermischt und schließlich in einem Schuss nacheinander in die entsprechenden Sektoren der Formkavität eingefüllt. Sobald der Füllvorgang beendet ist, beginnt die Rezeptur zu reagieren, wonach durch Schließen der Form der Gegenstand, in diesem Fall die Sohle, verpresst wird. For example, to stay with the example of a shoe sole, this shoe sole is divided into three sectors, namely a heel sector, a midfoot sector and a toe sector. For example, the toe sector should be red, the midfoot sector yellow, and the sales sector black. Then, in the order of later filling, the respective sector recipes of base material and corresponding additives are gradually introduced into the mixing head via the valve system, where they are mixed and finally filled in one shot one after the other into the corresponding sectors of the mold cavity. As soon as the filling process is over, the formula begins to react, after which the object, in this case the sole, is compressed by closing the mold.
Dieser Vorgang lässt sich sowohl im Spritzverfahren als auch im Gießverfahren ausführen. Beim Spritzverfahren gemäß Anspruch 3 ist der Mischkopf horizontal angeordnet, das heißt, dass seine Spritzrichtung parallel zur Kavitätsbodenebene verläuft. Der vom Anspritzpunkt entfernteste Sektor wird dann erreicht, wenn der Materialdurchsatz sehr hoch ist. Durch Verminderung des Materialdurchsatzes werden dann auch die beiden anderen Sektoren mit Material beaufschlagt. This process can be carried out both by spraying and by casting. In the spraying method according to
Bei der Gießmethode befindet sich der Mischkopf in vertikaler Stellung oberhalb der offenen Kavität und wird dabei durchsatzunabhängig entlang einer vorbestimmten Spur über den Kavitätsbereich verfahren, wobei dann die entsprechenden Rezepturen, Sektor für Sektor, eingefüllt werden. In the casting method, the mixing head is in a vertical position above the open cavity and is thereby traversed regardless of throughput along a predetermined track on the Kavitätsbereich, then the corresponding recipes, sector by sector, are filled.
Somit ergeben sich Objekte, in diesem Fall eine Sohle, deren einzelne Sektoren unterschiedlich in der Farbe, der Materialhärte, der Abrasionseigenschaften, Rutschfestigkeit, Dichte, Flexibilität etc. sind. This results in objects, in this case a sole, whose individual sectors are different in color, material hardness, abrasion properties, skid resistance, density, flexibility, etc.
Möglich wird die Führung eines derartigen Verfahrens, bei dem unterschiedliche Bereiche eines herzustellenden Objektes mit einem einzigen Mischkopf und in einem Schuss hergestellt werden können, durch eine Vorrichtung wie sie in Anspruch 8 dargestellt ist. It is possible to guide such a process, in which different areas of an object to be produced can be produced with a single mixing head and in one shot, by a device as described in claim 8.
Bei dem eingesetzten Mischkopf handelt es sich um eine, an sich bekannte, in einem Schneckenraum rotierbar angeordnete Mischschnecke, wobei der Schneckenraum in einer Düse endet und zwar konisch auf diese Düse zulaufend, so dass auch die darin rotierbar angeordnete Schnecke diese Konizität aufweist. Am, der Düsenöffnung gegenüberliegenden, Ende des Schneckenraumes münden Kanäle zum Einbringen des Grundmaterials/ der Grundmaterialien und der jeweils zu verarbeitenden Additive. In diesem Bereich ist radial um den Mischkopf herum eine Ventilanordnung vorgesehen, die die Zuführung des Grundmaterials und der Additive regelt. Die einzelnen Ventile sind mit den Dosiervorrichtungen für die Grundmaterialien und die Additive verbunden. The mixing head used is a mixing screw which is known per se and rotatable in a screw space, with the screw space ending in a nozzle, namely tapering to this nozzle, so that even the rotatably arranged therein screw has this conicity. At the end of the screw space opposite the nozzle opening, channels open for introducing the base material (s) and the respective additives to be processed. In this area, a valve arrangement is provided radially around the mixing head, which regulates the supply of the base material and the additives. The individual valves are connected to the metering devices for the base materials and the additives.
Aufgrund des Computermodells steuert eine intelligente Software die Dosiereinheit und die Ventilanordnung derart, dass für jeden Sektor zum entsprechenden Zeitpunkt die entsprechende Rezeptur in der Schnecke zur Verfügung steht. Due to the computer model, intelligent software controls the dosing unit and the valve arrangement such that the corresponding recipe in the screw is available for each sector at the appropriate time.
Beim oben angegebenen Beispiel werden über das Ventilsystem kurz hintereinander die entsprechenden Rezepturen in der Mischschnecke vermischt und entsprechend dem Programm in einem Schuss in die Kavität eingespritzt bzw. eingegossen. In the example given above, the corresponding recipes are mixed in the mixing screw in quick succession via the valve system and injected or poured into the cavity in a single shot according to the program.
Dabei ist die Formkavität gemäß dem behandelten Beispiel (Herstellung einer Sohle) durch zwei Formseitenteile und einen Bodenstempel gebildet, wobei die Seitenteile vor dem Füllvorgang zusammengefahren werden und der Bodenstempel nach Füllen und Aufschäumen von unten zur Verkleinerung des Kavitätsvolumens zugefahren wird, wodurch das Material verpresst wird. Dabei ist das die Kavität nach oben verschließende Element im vorliegenden Beispiel ein mit einem Schaft bezogener Leisten, wodurch beim Verpressvorgang die Sohle mit dem Schaft verbunden wird. In this case, the mold cavity according to the example treated (production of a sole) is formed by two mold side parts and a bottom punch, the side parts are collapsed before the filling and the bottom punch is closed after filling and foaming from below to reduce the Kavitätsvolumens, whereby the material is pressed , In the present example, the element which closes the cavity upwards is a strip which is related to a shaft, whereby the sole is connected to the shaft during the pressing process.
Die Erfindung ist wie oben bereits ausgeführt jedoch auf diese Ausführungsform nicht beschränkt. The invention is as stated above, however, not limited to this embodiment.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist für jedes Additiv ein mobiles Gestell vorgesehen, in dem eine Pumpe, ein Druckbehälter, eine Temperierung für den Druckbehälter, eine Steuerung für die Dosierung des jeweiligen Additivs sowie eine Verbindung zur Ventilanordnung vorgesehen. According to a preferred embodiment of the invention, a mobile frame is provided for each additive, in which a pump, a pressure vessel, a temperature control for the pressure vessel, a control for the metering of the respective additive and a connection to the valve assembly provided.
Dieses Gestell kann auf Rädern verfahrbar sein. Durch die Auslagerung der kompletten Hardware, die normalerweise in der Schuhmaschine verbaut wäre und dadurch, dass die auf dem Wagen angeordnete Anlage lediglich bezüglich der Stromversorgung und der Kommunikation von der Maschine abhängig ist, ansonsten aber autark ist, ist ein derartiges Additivgestell sehr flexibel, so dass es mit dem entsprechenden Softwarepaket und Hardwareerweiterung für die Dosierung jeweils eines Additivs zuständig ist. Dabei wird eine hochpräzise Spezialpumpe eingesetzt, insbesondere für niedrige Viskosität, welche eine Magnetkupplung zur Trennung von Fördermedium und Antrieb aufweist sowie einen Frequenzumrichter für eine sehr genaue Dosierung der Additive. This frame can be moved on wheels. By outsourcing the complete hardware that would normally be installed in the shoe machine and the fact that the system arranged on the carriage depends solely on the power supply and the communication of the machine, but otherwise is self-sufficient, such an additive rack is very flexible, so that it is responsible with the appropriate software package and hardware extension for the dosage of each additive. In this case, a high-precision special pump is used, in particular for low viscosity, which has a magnetic coupling for the separation of fluid and drive and a frequency converter for a very accurate metering of the additives.
Darüber hinaus ist für flüchtige Additive ein speziell konzipierter Druckbehälter vorgesehen, der über eine Flüssigtemperierung verfügt und über eine am Gestell untergebrachte Temperiereinheit geregelt wird. In addition, a specially designed pressure vessel is provided for volatile additives, which has a liquid temperature control and is regulated by a temperature control unit housed on the frame.
Durch die Konzeption dieser „Additivwagen“ ist es möglich, möglichst unabhängig von der Spritzgießmaschine selbst die jeweils benötigten Additive schnell zur Verfügung stellen zu können. Der für das jeweilige Additiv zuständige Wagen (Gestell) benötigt lediglich die Stromversorgung durch die Maschine bzw. eine Schnittstelle zur Kommunikation mit derselben. Durch die auf dem Gestell angeordnete Hardware sind schnell und zuverlässig Additive mit verschiedensten Eigenschaften exakt dosiert und über das Ventilsystem am Mischkopf demselben zuzuführen. Due to the design of this "additive car", it is possible, as independent as possible from the injection molding machine itself, to be able to quickly provide the additives required in each case. The responsible for the respective additive carriage (frame) only requires the power supply through the machine or an interface for communication with the same. Due to the hardware arranged on the frame, additives with a wide variety of properties can be dosed quickly and reliably and fed to it via the valve system on the mixing head.
Durch die exakte und schnelle Dosierung, Mischung im Schneckenraum und Ausbringung der entsprechenden Rezepturen im so genannten FIFO-Verfahren (first in-first out) ist es möglich, ein technisches Objekt (beispielsweise Sohle) in einem Schuss herzustellen, wobei eine relativ exakte Sektorentrennung eingehalten wird. Das heißt, dass die für den jeweiligen Sektor gewählten Eigenschaften im Großen und Ganzen auch nur in diesem verwirklicht sind. Due to the exact and rapid dosing, mixing in the screw space and application of the corresponding formulations in the so-called FIFO process (first in-first out), it is possible to produce a technical object (for example, sole) in one shot, with a relatively exact sector separation observed becomes. This means that the properties chosen for the respective sector are, on the whole, only realized in this sector.
