Diese Aufgabe wird gelöst durch eine Vorrichtung nach Anspruch 1. Die abhängigen Ansprüche definieren bevorzugte Ausführungsformen der erfindungsgemäßen Nutvorrichtung.This object is achieved by a device according to
Nach der Erfindung ist vorgesehen, dass sich der Auslauf im Bereich des oberen Scheitelpunktes der Transporttrommel befindet, sodass von den auslaufenden Pappenzuschnitten die geschnittenen Nuten nach oben zeigen. Dadurch sind während des Betriebs die geschnittenen Nuten von oben einsehbar und die Nutqualität kann ohne Entnahme von einzelnen Pappenzuschnitten fortlaufend an jeder ausgegebenen Pappe beurteilt werden. Insbesondere können so etwaig noch an der Pappe oder in den Nuten haftende Späne erkannt werden. Diese können, da sie nicht unter sondern oben auf der Pappe liegen, einfach weggeblasen oder weggebürstet werden. Die Ausgabe der Pappen mit nach oben zeigenden Nuten ermöglicht außerdem die direkte Weiterverarbeitung in nachfolgenden Einrichtungen, ohne die Pappenzuschnitte dafür wenden zu müssen, wie z.B. in einer Kaschiermaschine, in der die Pappen mit der unten liegenden, nutfreien Seite auf Bezugsmaterialen geklebt werden. Mit der Ausgabe der genuteten Pappenzuschnitte am oberen Scheitelpunkt der Transporttrommel ergibt sich zudem eine ergonomisch günstige Abnahmehöhe, insbesondere wenn die Pappen im Anschluss an den Auslauf auf einen tiefer liegenden Auslagetisch abgeworfen werden.According to the invention, it is provided that the outlet is in the region of the upper vertex of the transport drum, so that the cut grooves point upwards from the leaking cardboard blank. As a result, the cut grooves are visible from above during operation and the groove quality can be assessed without removing individual cardboard blanks continuously on each output cardboard. In particular, any chips still adhering to the cardboard or in the grooves can thus be detected. These can, as they are not under but on top of the cardboard, simply blown away or brushed away. The output of the boards with upwardly facing grooves also allows direct further processing in subsequent facilities without having to turn over the board blank as e.g. in a laminating machine in which the cardboard with the bottom, groove-free side are glued to cover materials. With the output of the grooved cardboard blanks at the upper vertex of the transport drum also results in an ergonomically favorable decrease height, especially when the boards are dropped following the spout on a lower-lying delivery table.
In einer Weiterbildung ist vorgesehen, dass erste Rollen in einem Abstand vor dem Auslauf angeordnet sind, sodass die Riemen einen tangential von der Transporttrommel ablaufenden Trum aufweisen. Hierdurch kann ein unerwünschter Walk- und Biegeeffekt im Auslauf deutlich verringert werden und die Pappen werden nahezu planliegend ausgegeben. Außerdem kann damit ein Weitertransport verwirklicht werden, beispielsweise mit einem darunter angeordneten Rollenteppich oder indem die Riemen als Saugriemen ausgebildet sind.In a further development, it is provided that first rollers are arranged at a distance in front of the outlet, so that the belts have a run tangentially from the transport drum. As a result, an undesirable flexing and bending effect in the outlet can be significantly reduced and the boards are output almost planliegend. In addition, so that a further transport can be realized, for example, with an underlying roller carpet or by the belts are designed as a suction belt.
Die manuelle Abnahme kann weiter rationalisiert bzw. für eine maschinelle Abnahme vorbereitet werden, wenn eine dem Auslauf nachgeordnete, einen Stapel auf einer zum Auslauf tiefer liegenden Ebene bildende bzw. ausgebende Stapeleinrichtung vorgesehen ist. Dadurch dass in dem Stapel der jeweils zuletzt genutete Pappenzuschnitt mit oben liegender Nutseite oben auf liegt, kann während dem Stapeln auf Paletten eine einfache visuelle Qualitätskontrolle erfolgen, ohne dafür einen Pappenzuschnitt aus dem Stapel entnehmen zu müssen.The manual decrease can be further rationalized or prepared for a mechanical decrease, if a downstream of the outlet, a stack is provided on a lower level to the outlet level or stacking device. The fact that in the stack of each last grooved cardboard blank with overhead Groove side is on top, can be done while stacking on pallets a simple visual quality control, without having to remove a cardboard blank from the stack.
Ein ungehinderter Zugang zur Transporttrommel ist dadurch gewährleistet, dass nach einer Weiterbildung die genuteten Pappenzuschnitte von einem quer zum Auslauf verlaufenden Transportband abgefördert werden, um die Pappenzuschnitte beispielsweise zu einer nebenstehend gekoppelten Weiterverarbeitungseinrichtung zu überführen. Wenn die genuteten Pappenzuschnitte in einem nach vorn untereinander liegenden Schuppenstrom auf dem Transportband abgelegt und abgefördert werden, bildet sich ein quasi endloser Stapel aus, welcher unabhängig vom Maschinenlauf in beliebigen Teilmengen entnommen werden kann. Außerdem ermöglicht der geschuppte Abtransport die Inaugenscheinnahme zumindest eines Bereichs der geschnittenen Nuten aller Pappenzuschnitte.Unimpeded access to the transport drum is ensured by the fact that after a further development, the grooved cardboard blanks are conveyed away from a transversely extending to the outlet conveyor belt to transfer the cardboard blanks, for example, to a side coupled further processing device. When the grooved cardboard blanks are stored and conveyed away on a conveyor belt in a shingled stream lying in front of one another, a quasi-endless stack is formed, which can be removed in arbitrary subsets independently of the machine run. In addition, the shingled removal allows the inspection of at least a portion of the cut grooves of all cardboard blanks.
In einer Weiterbildung ist vorgesehen, dass die Zuführung zum Einlauf und die Wegführung vom Auslauf bezüglich einer durch die Trommelachse bestimmten Vertikalebene auf der gleichen Seite der Transporttrommel liegen, sodass das Anlegen und das Abnehmen der Pappenzuschnitte bedienungsfreundlich auf einer gemeinsamen Bedienseite erfolgen und die Nutenschneidwerkzeuge bei guter Zugänglichkeit und freier Ableitung der anfallenden Späne auf der gegenüberliegenden Werkzeugseite anordnebar sind.In a further development, it is provided that the supply to the inlet and the path leading from the outlet with respect to a vertical plane determined by the drum axis on the same side of the transport drum, so that the application and removal of the cardboard blank done easy to use on a common operating page and the Nutenschneidwerkzeuge with good Accessibility and free derivation of the resulting chips on the opposite side of the tool are anordnebar.
Vorzugweise befindet sich der Einlauf im Bereich des unteren Scheitelpunktes der Transporttrommel, wobei die Pappenzuschnitte von Fördermitteln im Wesentlichen flachliegend dem Einlauf zugeführt werden. Die Pappenzuschnitte werden der Transporttrommel tangential zugeführt und in ihrer flachliegenden Orientierung vom Einlauf übernommen. Die Ausgestaltung mit dem Einlauf am unteren Scheitelpunkt und dem Auslauf am oberen Scheitelpunkt ergibt eine etwa 180° Umschlingung der Transporttrommel durch die Riemen und damit eine ausreichend lange Förderstrecke zur Anordnung verschiedener in Transportrichtung nacheinander angeordneter Schneid- und Bearbeitungswerkzeuge.Preferably, the inlet is in the region of the lower vertex of the transport drum, wherein the cardboard blanks of conveying means are fed substantially flat lying the inlet. The cardboard blanks are fed tangentially to the transport drum and taken over in their flat orientation from the inlet. The embodiment with the inlet at the lower vertex and the outlet at the upper vertex results in an approximately 180 ° looping of the transport drum through the belt and thus a sufficiently long conveyor line for arranging different in the transport direction successively arranged cutting and processing tools.
Vorzugsweise ist ein Zuführförderer mit an der Pappenhinterkante schiebenden Pappenschiebern vorgesehen, mit dem die Pappenzuschnitte unter seitlicher Ausrichtung an Führungsschienen und mit geringer Übergeschwindigkeit zur Transporttrommel dem Einlauf zugeführt werden. Die Pappenzuschnitte werden an der Hinterkante und zu einer Seitenkante exakt ausgerichtet und in dieser Orientierung aufgrund der Übergeschwindigkeit quasi zwangsweise in den Einlauf zwischen Transporttrommel und Riemen eingeschoben. Es liegt eine getaktete Verarbeitung vor, wodurch die direkte Übernahme respektivePreferably, a feed conveyor is provided with sliding on the cardboard trailing edge cardboard sliders, with which the cardboard blanks are fed to the inlet under lateral alignment on guide rails and at a slight overspeed to the transport drum. The cardboard blanks are precisely aligned at the trailing edge and to one side edge and, in this orientation, due to the overspeed, are forced almost forcibly into the inlet between the transport drum and the belt. There is a clocked processing, whereby the direct acquisition respectively
Übergabe aus vor- respektive nachgeordneten taktweise arbeitenden Maschinen ermöglicht wird. Dadurch dass bei besagter getakteter Verarbeitung die jeweilige Förderposition der Pappenzuschnitte bekannt ist, können zusätzlich zum Nuten höhenpositionsabhängige Bearbeitungen, wie das Abstanzen von Ecken oder das Einbringen von Querrillen oder dgl. Nutzungsstellen, an den einzelnen Pappenzuschnitten ausgeführt werden.Transfer from upstream or downstream cyclically operating machines is made possible. The fact that the respective conveying position of the board blanks is known in said clocked processing, in addition to the grooves height-position-dependent processing, such as the punching of corners or the introduction of transverse grooves or the like. Use points, can be performed on the individual cardboard blank.
Vorzugsweise sind zweite Rollen in einem Abstand vor dem Einlauf angeordnet, sodass die Riemen einen tangential zur Transporttrommel zulaufenden Trum aufweisen. Neben der deutlichen Verringerung des Walk- und Biegeeffekts im Einlauf unterstützt das Fördertrum die Ausrichtung der Pappenzuschnitte an den etwas schneller laufenden Pappenschiebern des Zuführförderers.Preferably, second rollers are arranged at a distance in front of the inlet, so that the belt have a tangent tangentially to the transport drum strand. In addition to the significant reduction in the flexing and bending effect in the infeed, the conveying run supports the orientation of the cardboard blanks on the feeders of the feed conveyor, which are slightly faster.
In einer Weiterausbildung ist ein einen Stapel Pappenzuschnitte aufnehmendes Pappenmagazin vorgesehen, aus dem der jeweils unterste Pappenzuschnitt vereinzelt und dem Einlauf zugeführt wird. Pappen können ohne Halt der Nutvorrichtung auf einer höheren und damit ergonomisch günstigeren Anlegehöhe nachgelegt werden. Das Pappenmagazin ist ein als FiFo-Speicher (First-in-First-out) arbeitender Puffer und insbesondere vorteilhaft für die Kopplung der Nutvorrichtung mit einer Vormaschine. Mit dem Vorteil einer weiter erhöhten Speicherkapazität und einer nochmals verbesserten ergonomischen Anlegehöhe ist dem Pappenmagazin ein Vorstapelband zur Aufnahme von geschuppt oder in Stapeln angelegten Pappenzuschnitten zugeordnet, welches die Pappenzuschnitte nach dem Magazinfüllstand gesteuert dem Pappenmagazin automatisch zuführt.In a further development, a cardboard magazine receiving a stack of cardboard blanks is provided, from which the respective lowermost cardboard blank is singled out and fed to the inlet. Cardboards can be added without stopping the groove device on a higher and thus more ergonomic Anlegehöhe. The cardboard magazine is a buffer that operates as FIFO storage (first-in-first-out) and is particularly advantageous for coupling the grooving device to a pre-machine. With the advantage of a further increased storage capacity and a further improved ergonomic application height, the paperboard magazine is assigned a pre-stacking belt for receiving scalloped or stacked paperboard blanks which automatically feed the paperboard sections to the paperboard magazine according to the magazine filling level.
