Abstract

The invention concerns a cutting station (10) for cutting a plastically deformable material strip which is continuously fed on a line (14) of contiguous bottom-half moulds (12) of equal length into individual shaped parts at the ends of the bottom-half moulds (12). At least one cutting device (28) is mounted on a sliding carriage (20) which can be moved in a reversible manner. During the cutting operation, the bottom-half moulds (12) are guided by guide components (50, 52, 54). In order to provide a cutting station of the initially-mentioned type, which can be rapidly re-equipped for differently shaped parts, in particular for concrete roofing tiles of different shapes, the cutting device (28) is mounted on an intermediate frame (26) which can be secured to the sliding carriage (20). The guide components (50, 52, 54) are mounted on an adapter (46) which can be secured to the cutting station (10). Advantageously, the intermediate frame can be positioned on the sliding carriage (20) and the adapter (46) can be positioned at the cutting station (10) via fitting components.

B e s c h r e i b u n g Description
Schneidstation zum Zerschneiden eines kontinuierlich geförderten Bandes aus plastisch verformbarem Material in einzelne FormstückeCutting station for cutting a continuously conveyed band of plastically deformable material into individual shaped pieces
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 a band of plastically deformable material, which is continuously conveyed on a strand and abutted against one another, of the same length into individual shaped pieces at the ends of the lower molds, at least one cutting device being attached to a reversibly movable carriage, and 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 required, for example, in the production of concrete roof tiles using the extrusion process. In this process, a fresh concrete layer is applied as an endless band on a strand of mutually abutting lower molds of the same length, which is conveyed at a constant speed, and which is shaped on the top by means of molding tools corresponding to the surface contour customary for concrete roof tiles. This continuously applied fresh concrete layer is then cut in a cutting station at the end of each lower mold by means of a cutting device with a knife, so that each lower mold carries a single molded body, here a concrete roof blank. For this it is necessary that the knife is always inserted exactly into the fresh concrete layer at the joint between two sub-molds. Usually the strand moves in the horizontal direction and the knife in the vertical direction.
Eine Schneidstation der eingangs geschilderten Art ist aus der DE-C 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 un neu justiert werden. Hierzu ist eine beträchtliche Umrüstzei erforderlich, während der die gesamte Produktionsanlage stillsteht.A cutting station of the type described at the outset is known from DE-C 22 52 047. In this cutting station, the knife, which is actuated by a compressed air cylinder, is mounted on a slide which is reversibly movable in the horizontal direction Connecting rod is driven. The cutting device is screwed onto the slide, the guide elements are screwed onto the cutting station. When changing the model of the concrete roof tiles produced, the cutting device and the guide elements must be replaced and readjusted. This requires a considerable changeover time during which the entire production plant is at a standstill.
Aufgabe der vorliegenden Erfindung ist es, eine Schneidstati 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.It is an object of the present invention to provide a cutting status of the type described at the outset, in which the changeover for differently shaped fittings, in particular for concrete roof tiles of different shapes, is possible in a short time.
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 which can be attached to the slide, and in that the guide elements are mounted on an adapter which can be attached to the cutting station.
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.This design makes it possible to completely replace the cutting device with all accessories with the intermediate frame and also to completely replace the guide elements adjusted on the adapter with the adapter.
Dadurch wird die Umrüstzeit auf einen Zeitraum von wenigen Minuten reduziert.This reduces the changeover time to a few minutes.
Eine gesonderte Justierung der Schneideinrichtung ist nicht erforderlich, wenn der Zwischenrahmen am Schlitten überA separate adjustment of the cutting device is not necessary if the intermediate frame on the carriage
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.Fitting elements can be positioned. In this way it is achieved that the replaced intermediate frame is used immediately in the correct position for the slide and only needs to be attached to it.
Der gleiche Vorteil ergibt sich, wenn der Adapter an der Schneidstation über Paßelemente positionierbar ist. 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.The same advantage is obtained if the adapter can be positioned at the cutting station using fitting elements. For example, in order to provide an end face of a shaped piece with a special contour, a dressing device with a dressing tool can be attached to the slide. This is desirable, for example, to round off the top edge of a concrete roof tile on the foot side.
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 driven by a double-acting compressed air cylinder so that the cut can be made particularly quickly. If available, the dressing tool is also moved pneumatically. In order to prevent concrete from sticking to the knife or dressing tool, it is advantageous if it is cleaned in the rest position.
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 rapid replacement of the intermediate frame, it is advantageous if all supply lines to the devices attached to the intermediate frame can be connected to the cutting station via a quick coupling. In this way, all compressed air, power and liquid lines can be separated or connected to each other with a single handle.
Die Führungselemente sind erforderlich, um während des Schneidvorgangs ein Ausweichen einer Unterform nach unten oder zur Seite zu verhindern. Da die Unterformen an denThe guide elements are required to prevent a lower mold from moving downwards or to the side during the cutting process. Since the subforms on the
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.Slide guide elements along, it is advantageous if they have at least one wear-reducing coated surface. For example, a layer of hard metal can be applied to the surface of the guide elements or the guide elements can be designed as hard metal plates.
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. 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 Unterform auszugleichen vermag.Exact lateral guidance is achieved if at least two lateral guide elements are provided, which can be designed as guide strips and rest on mutually opposite guide surfaces of the lower mold. A particularly exact guidance of the lower molds during the cutting process is achieved if at least one of the lateral guide elements can be displaced transversely to the conveying direction of the lower mold, so that this can compensate for small tolerances between individual lower molds due to its transverse movement.
Eine konstante Führungskraft wird eingehalten, wenn das querverschiebbare zweite seitliche Führungselement pneumatis gegen die Unterform anpreβbar 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 guide force is maintained if the second side guide element, which can be moved laterally, can be pressed pneumatically against the lower mold. A pneumatic cylinder, for example, can act on the second lateral guide element. The pneumatic cylinder presses the second lateral guide element against one of the lateral guide surfaces of the lower mold and thus the lower mold against the opposite first lateral guide element, which then forms the reference surface.

The first lateral guide element 154 is arranged on the top of the adapter 146, while the second lateral guide element 156 is fastened to a projection 158 of the carrier piece 46. When converting the cutting station 10 from the production with sub-molds 112 for the production of verge stones to other sub-molds, for example for the production of normal ones
Betondachsteine oder auf erste Unterformen 12 zur Herstellun 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 Benutzun 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 d 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. Concrete roof tiles or on first subforms 12 for the production of ridge or ridge stones, only the adapter 146 is exchanged for another one, for example a first adapter 46. It goes without saying that when using the cutting station 10 with the first adapter 46, the second lateral guide element 156 can remain on the carrier piece 48. The required replacement of the adapter 146 with the adapter 46 can be done within a very short time when converting Changeover time. Likewise, the intermediate frame 28 can be quickly replaced by another intermediate frame on which the cutting device 28 required for the other Dachstein model and, if necessary, a dressing device 34 are mounted in an exactly adjusted manner.
