Abstract
Description
Die Erfindung betrifft eine Schneidstation zum Zerschneiden eines kontinuierlich auf einem Strang aneinanderstoßender Unterformen von gleicher Länge geförderten Bandes aus plastisch verformbarem Material in einzelne Formstücke an den Enden der Unterformen, wobei zumindest eine Schneideinrichtung an einem reversierend bewegbaren Schlitten angebracht ist und die Unterformen während des Schneidvorgangs durch Führungselemente geführt sind.The invention relates to a cutting station for cutting one continuously colliding on one strand Sub-forms of the same length of conveyed belt plastically deformable material in individual moldings on the Ends of the lower molds, with at least one cutting device is attached to a reversibly movable carriage and through the lower molds during the cutting process Guide elements are guided.
Eine derartige Schneidstation wird beispielsweise bei der Herstellung von Betondachsteinen nach dem Strangpreßverfahren benötigt. Bei diesem Verfahren wird auf einem mit konstanter Geschwindigkeit geförderten Strang von aneinanderstoßenden Unterformen gleicher Länge eine Frischbetonschicht als endloses Band aufgebracht, das auf der Oberseite durch Formwerkzeuge der für Betondachsteine üblichen Oberflächenkontur entsprechend geformt wird. Diese kontinuierlich aufgebrachte Frischbetonschicht wird anschließend in einer Schneidstation jeweils am Ende einer jeden Unterform mittels einer Schneideinrichtung mit einem Messer zerschnitten, so daß jede Unterform einen einzelnen Formkörper trägt, hier einen Betondachsteinrohling. Dazu ist es erforderlich, daß das Messer stets exakt an der Stoßstelle zwischen zwei Unterformen in die Frischbetonschicht eingeführt wird. Üblicherweise bewegt sich der Strang in horizontaler Richtung und das Messer in vertikaler Richtung.Such a cutting station is used, for example, at Manufacture of concrete roof tiles using the extrusion process needed. This method is based on a constant Speed promoted strand of abutting Subforms of equal length as a fresh concrete layer Endless tape applied through the top Forming tools of the usual for concrete roof tiles Surface contour is shaped accordingly. This continuously applied fresh concrete layer then in a cutting station at the end of each each lower mold by means of a cutting device with a Knives cut so that each subform is a single one Molded body carries, here a concrete roof tile blank. Is to it is necessary that the knife is always exactly at the joint inserted between two sub-forms in the fresh concrete layer becomes. The strand usually moves horizontally Direction and the knife in the vertical direction.
Eine Schneidstation der eingangs geschilderten Art ist aus der DE-A-22 52 047 bekannt. Bei dieser Schneidstation ist das von einem Druckluftzylinder betätigte Messer an einem in horizontaler Richtung reversierbar bewegbaren Schlitten montiert, wobei der Schlitten über eine Kurbel und Pleuelstange angetrieben wird. Die Schneideinrichtung ist am Schlitten angeschraubt, die Führungselemente sind an der Schneidstation angeschraubt. Bei einem Modellwechsel der produzierten Betondachsteine müssen jeweils die Schneideinrichtung und die Führungselemente ausgewechselt und neu justiert werden. Hierzu ist eine beträchtliche Umrüstzeit erforderlich, während der die gesamte Produktionsanlage stillsteht.A cutting station of the type described is from the DE-A-22 52 047 known. With this cutting station it is from an air cylinder operated knife on an in horizontally reversible movable carriage mounted, the slide over a crank and Connecting rod is driven. The cutting device is on Screwed on slide, the guide elements are on the Screwed on cutting station. When changing the model produced concrete roof tiles must each Cutting device and the guide elements replaced and be readjusted. This requires a considerable changeover time required throughout the entire production facility stands still.
Aufgabe der vorliegenden Erfindung ist es, eine Schneidstation der eingangs geschilderten Art zur Verfügung zu stellen, bei der das Umrüsten für verschieden geformte Formstücke, insbesondere für Betondachsteine unterschiedlicher Form, in kurzer Zeit möglich ist.The object of the present invention is a cutting station of the kind described at the beginning the changeover for differently shaped fittings, especially for concrete roof tiles of different shapes, in short time is possible.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Schneideinrichtung an einem Zwischenrahmen montiert ist, der am Schlitten befestigbar ist, und daß die Führungselemente an einem Adapter montiert sind, der an der Schneidstation befestigbar ist.According to the invention the object is achieved in that the Cutting device is mounted on an intermediate frame, the is attachable to the carriage, and that the guide elements an adapter are mounted on the cutting station is attachable.
Diese Ausführung ermöglicht es, die Schneideinrichtung komplett mit sämtlichem Zubehör mit dem Zwischenrahmen auszutauschen und ebenso die am Adapter justierten Führungselemente komplett mit dem Adapter auszutauschen. Dadurch wird die Umrüstzeit auf einen Zeitraum von wenigen Minuten reduziert.This design enables the cutting device complete with all accessories with the intermediate frame replace and also those adjusted on the adapter Guide elements to be replaced completely with the adapter. This reduces the changeover time to a few Minutes reduced.
Eine gesonderte Justierung der Schneideinrichtung ist nicht erforderlich, wenn der Zwischenrahmen am Schlitten über Paßelemente positionierbar ist. Auf diese Weise wird erreicht, daß der ausgewechselte Zwischenrahmen sofort in der richtigen Position zum Schlitten eingesetzt wird und nur noch daran befestigt werden muß.A separate adjustment of the cutting device is not required if the intermediate frame on the slide over Fitting elements can be positioned. In this way it is achieved that the replaced intermediate frame is immediately in the correct one Position used for the slide and only on it must be attached.
Der gleiche Vorteil ergibt sich, wenn der Adapter an der Schneidstation über Paßelemente positionierbar ist. The same advantage arises when the adapter on the Cutting station can be positioned using fitting elements.
Um beispielsweise eine Stirnseite eines Formstücks mit einer besonderen Kontur zu versehen, kann am Schlitten eine Zurichteinrichtung mit einem Zurichtwerkzeug angebracht sein. Dies ist wünschenswert, um beispielsweise die fußseitige Oberkante eines Betondachsteins abzurunden.For example, around an end face of a fitting with a To provide a special contour, a Dressing device can be attached with a dressing tool. This is desirable, for example, around the foot Round off the top edge of a concrete roof tile.
Üblicherweise wird das Messer der Schneideinrichtung von einem doppelt wirkenden Druckluftzylinder angetrieben, damit der Schnitt besonders rasch erfolgen kann. Ebenso wird, falls vorhanden, das Zurichtwerkzeug pneumatisch bewegt. Um ein Ankleben von Beton am Messer bzw. Zurichtwerkzeug zu verhindern, ist es vorteilhaft, wenn diese jeweils in Ruhestellung gereinigt werden.The knife of the cutting device is usually used by one double-acting pneumatic cylinder driven so that Cut can be done particularly quickly. Likewise, if available, the dressing tool moves pneumatically. To a Glue concrete to the knife or dressing tool prevent it, it is advantageous if these each in Rest position to be cleaned.
Um ein rasches Auswechseln des Zwischenrahmens zu ermöglichen, ist es vorteilhaft, wenn sämtliche Versorgungsleitungen zu den am Zwischenrahmen angebrachten Einrichtungen über eine Schnellkupplung mit der Schneidstation verbindbar sind. Auf diese Weise können mit einem einzigen Handgriff sämtliche Druckluft-, Strom- und Flüssigkeitsleitungen getrennt bzw. miteinander verbunden werden.In order to enable the intermediate frame to be replaced quickly, it is advantageous if all supply lines to the devices attached to the intermediate frame via a Quick coupling can be connected to the cutting station. On this way, all can be done with a single movement Compressed air, power and liquid lines separated or be connected to each other.
Die Führungselemente sind erforderlich, um während des Schneidvorgangs ein Ausweichen einer Unterform nach unten oder zur Seite zu verhindern. Da die Unterformen an den Führungselementen entlang gleiten, ist es vorteilhaft, wenn diese zumindest eine verschleißmindernd beschichtete Oberfläche aufweisen. Beispielsweise kann auf der Oberfläche der Führungselemente eine Schicht aus Hartmetall aufgebracht sein oder die Führungselemente können als Hartmetallplatten ausgebildet sein.The guide elements are required to during the Cutting a dodging a subform or down to the side to prevent. Since the subforms on the Sliding along guide elements, it is advantageous if this at least one coated to reduce wear Have surface. For example, on the surface a layer of hard metal is applied to the guide elements or the guide elements can be as hard metal plates be trained.
Eine exakte seitliche Führung wird erreicht, wenn zumindest Zwei seitliche Führungselemente vorgesehen sind, die als Führungsleisten ausgebildet sein können und an einander gegenüberliegenden Führungsflächen der Unterform anliegen. Exact lateral guidance is achieved if at least Two side guide elements are provided, which as Guide rails can be formed and on each other lie opposite guide surfaces of the lower mold.
Eine besonders exakte Führung der Unterformen während des Schneidvorgangs wird erzielt, wenn zumindest eines der seitlichen Führungselemente quer zur Förderrichtung der Unterform verschiebbar ist, so daß dieses infolge seiner Querbewegung geringe Toleranzen zwischen einzelnen Unterformen auszugleichen vermag.A particularly precise guidance of the lower molds during the Cutting process is achieved when at least one of the lateral guide elements transverse to the conveying direction of the Lower mold is slidable, so that this is due to its Cross movement small tolerances between individual sub-forms is able to compensate.
Eine konstante Führungskraft wird eingehalten, wenn das querverschiebbare zweite seitliche Führungselement pneumatisch gegen die Unterform anpreßbar ist. Auf das zweite seitliche Führungselement kann beispielsweise ein Pneumatikzylinder einwirken. Der Pneumatikzylinder preßt das zweite seitliche Führungselement an eine der seitlichen Führungsflächen der Unterform an und somit die Unterform gegen das gegenüberliegende erste seitliche Führungselement, das dann die Bezugsfläche bildet.A constant manager is maintained if that Pneumatically displaceable second lateral guide element can be pressed against the lower mold. On the second side A pneumatic cylinder can be a guide element, for example act. The pneumatic cylinder presses the second side Guide element on one of the side guide surfaces of the Lower mold on and thus the lower mold against that opposite first lateral guide element, which then forms the reference surface.

Strangs 14 angeordnet und in Horizontalführungen verschiebbar
gelagert. Über einen hier nicht dargestellten Antrieb ist der
Schlitten 20 zumindest während einer kurzen Wegstrecke mit
derselben Geschwindigkeit wie der Strang 14 bewegbar.
Innerhalb dieser Wegstrecke erfolgt der Schneidvorgang. Am
Schlitten 20 sind zwei den Strang 14 überragende
Auslegerarme 22, 24 mit T-Nuten vorgesehen, auf denen ein
Zwischenrahmen 26 mit T-Nuten-Steinen paßgenau befestigt ist.1 shows a
Der Zwischenrahmen 26 trägt eine Schneideinrichtung 28, die
als Schneidwerkzeug ein von einem doppeltwirkenden
Druckluftzylinder 30 quer zur Förderrichtung 16 in vertikaler
Richtung bewegbares Messer 32 aufweist. Weiterhin ist am
Zwischenrahmen 26 eine Zurichteinrichtung 34 angebracht, die
ein Zurichtwerkzeug 36 aufweist, das von einem
doppeltwirkenden Preßluftzylinder 38 ebenfalls quer zur
Förderrichtung 16 bewegbar ist. Sämtliche Versorgungsleitungen
zu den am Zwischenrahmen angeordneten Einrichtungen,

dem Trägerstück 48 montiert ist. Der zweite Adapter 146 ist
für Unterformen 112 ausgebildet, die zur Herstellung von
Ortgangsteinen geeignet sind. Der zweite Adapter 146 weist
insgesamt 3 horizontale Führungselemente 150, 151, 152 auf,
die als Hartmetallplatten ausgebildet sind. Das erste
seitliche Führungselement 154 ist auf der Oberseite des
Adapters 146 angeordnet, während das zweite seitliche
Führungselement 156 an einer Auskragung 158 des
Trägerstücks 46 befestigt ist. Beim Umrüsten der
Schneidstation 10 von der Produktion mit
Unterformen 112 zur Herstellung von Ortgangsteinen auf andere
Unterformen, beispielsweise zur Herstellung normaler
Betondachsteine oder auf erste Unterformen 12 zur Herstellung
von First- oder Gratsteinen, wird lediglich der Adapter 146
gegen einen anderen, beispielsweise einen ersten Adapter 46,
ausgewechselt. Es versteht sich von selbst, daß bei Benutzung
der Schneidstation 10 mit dem ersten Adapter 46 das zweite
seitliche Führungselement 156 am Trägerstück 48 verbleiben
kann. Das erforderliche Auswechseln des Adapters 146 gegen den
Adapter 46 kann beim Umrüsten innerhalb einer sehr kurzen
Umrüstzeit erfolgen. Ebenso kann der Zwischenrahmen 28 schnell
gegen einen anderen Zwischenrahmen ausgetauscht werden, auf
dem die für das andere Dachsteinmodell erforderliche
Schneideinrichtung 28 und gegebenenfalls eine
Zurichteinrichtung 34 exakt justiert montiert sind.Fig. 4 shows in cross section a
