Description
Die Erfindung betrifft eine Transfereinheit entsprechend dem Oberbegriff des Anspruchs 1.The The invention relates to a transfer unit according to the preamble of claim 1.

Aus der US Patentschrift 4,947,538 ist eine Werkzeugmaschine bekannt, bei der ein zustellbarer Werkstückgreifer am Querschlitten der Bearbeitungseinheit angeordnet ist. Die Zustellbewegung des Greifers ist wegen der Anbringung am Querschlitten jedoch als eine zusätzliche, gesteuerte Handhabungsachse ausgeführt. Für die Zustellbewegung muss ein erweiterter Verfahrbereich der Querachse vorgesehen werden, welcher für Bearbeitungsoperationen gesperrt ist, um den Greifer während der Bearbeitung außerhalb des Kollisionsbereichs von Arbeitsspindel und Werkstück zu halten. Auch ergibt sich mit der gewählten Anordnung des Greifers ein großer Abstand von der Bearbeitungsposition zur Greifposition, wodurch eine sehr lange Längsachse erforderlich wird. Außerdem ist eine einfache Abschottung des Arbeitsraums nur mit großem Aufwand zu realisieren, weil der Greifer einen zusätzlichen seitlichen Kollisionsbereich darstellt.Out US Pat. No. 4,947,538 discloses a machine tool in the case of a deliverable workpiece gripper is arranged on the cross slide of the processing unit. The delivery movement of Gripper is because of the attachment to the cross slide, however, as one additional controlled handling axis executed. For the delivery movement must an extended traversing range of the transverse axis is provided, which for Machining operations is locked to the gripper during the Processing outside to keep the collision area of work spindle and workpiece. Also results with the chosen Arrangement of the gripper a big one Distance from the machining position to the gripping position, whereby a very long longitudinal axis is required. Furthermore is a simple foreclosure of the work space only with great effort because the gripper has an additional lateral collision area represents.
Aus dem Stand der Technik sind Transfermodule, beispielsweise des Herstellers Elha-Maschinenbau, Liemke KG, bekannt. Bei diesen Modulen sind die Werkzeuge in einer Art fest angeordnetem Mehrspindelkopf in mehreren Ebenen übereinander oder nebeneinander angeordnet. Zur Bearbeitung werden die Werkzeuge mit der Werkstückspannvorrichtung nacheinander in Eingriff gebracht. Die Zugänglichkeit der Transfermodule ist jedoch durch das vor den Modulen angeordnete Werkstücktransportband stark eingeschränkt. Außerdem wird eine zusätzliche Werkstückhandhabungstechnik zum Betrieb des Transfermoduls benötigt.Out the prior art are transfer modules, for example, the manufacturer Elha-Maschinenbau, Liemke KG, known. These modules are the Tools in a kind of fixed multi-spindle head in several Layers on top of each other or arranged side by side. For editing, the tools with the workpiece clamping device engaged one after the other. The accessibility of the transfer modules is however through the arranged in front of the modules workpiece conveyor belt highly limited. Furthermore will be an extra Workpiece handling technology needed to operate the transfer module.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Anordnung zu finden mit der eine Transfereinheit mit kurzen Span-zu-Span-Zeiten für die Serienbearbeitung konzipiert wird, welche auch einen schnellen Werkstückwechsel möglich macht, wobei zum Wechseln und Handhaben von Werkstücken keine zusätzlichen gesteuerten Achsen notwendig sein sollen und die entsprechenden Greifeinrichtungen durch die vorhandenen Hauptachsen bzw. durch die Positioniereinrichtung des Werkstücktransportbandes in Eingriff gebracht werden sollen, wobei die Maschine gut zugänglich sein soll und zur Reduzierung von Entwicklungskosten die Grundkonstruktion auf der Konstruktion eines herkömmlichen vertikalen oder horizontalen Bearbeitungszentrums basieren soll.Of the The invention is therefore based on the object, an arrangement find with the one transfer unit with short chip-to-chip times for series processing which is also a fast workpiece change possible makes, for changing and handling of workpieces no additional controlled axles should be necessary and the corresponding Gripping devices through the existing main axes or through the Positioning device of the workpiece conveyor belt engaged should be brought, the machine being easily accessible and to reduce development costs the basic construction the construction of a conventional vertical or horizontal machining center.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Kern der Erfindung ist demnach, dass ein um eine vertikale Achse drehbarer Werkzeugmehrspindelkopf im Zentrum der Drehachse einen zustellbaren Werkstückdoppelgreifer aufweist, weicher in zugestellter Position sowohl auf die Werkstückspannvorrichtung als auch auf das Werkstücktransportband zugreift und durch Drehung um 180° den Werkstückwechsel ausführt und dass die Werkzeuge im Werkzeugmehrspindelkopf sowohl in mehreren Ebenen übereinander liegen als auch an mehreren Seiten des Kopfes angeordnet sind.According to the invention Problem solved by the features of claim 1. Core of The invention is therefore that a rotatable about a vertical axis Tool multi-spindle head in the center of the axis of rotation an undeliverable Workpiece double gripper softer in the delivered position on both the workpiece clamping device as well as on the workpiece conveyor belt accesses and by turning through 180 ° the Workpiece change carries and that the tools in the multi-spindle head both in several Layers on top of each other lie as well as on several sides of the head are arranged.
