Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Nuten von Pappenzuschnitten nach dem Oberbegriff des Anspruchs 1.The present invention relates to a device for grooving cardboard blank according to the preamble of claim 1.

Buchdecken als auch Schachteln für hochwertige Verkaufs- und Geschenkverpackungen bestehen im Kern aus Pappen, die mit Bezugsmaterialien kaschiert sind. Zur Vorbereitung von Biegestellen oder scharfkantigen Abkantungen werden die Pappenzuschnitte an den entsprechenden Stellen genutet. Der Nutquerschnitt kann ein dreieckiges bis rechteckiges Profil aufweisen, das als Span mit dementsprechend zueinander stehenden Messerklingen oder Rundmessern und ggf. eines dazwischen angeordneten Aushebers oder mit einteiligen, nach dem jeweiligen Querschnitt geformten Spezialmessern aus den Pappen herausgeschnitten wird.Bookbases as well as boxes for high-quality sales and gift packaging consist of cardboard core covered with cover materials. To prepare for bending points or sharp-edged folds, the cardboard blanks are grooved in the appropriate places. The groove cross-section may have a triangular to rectangular profile, which is cut out of the cardboard as a chip with correspondingly standing knife blades or circular blades and possibly an interposed Aushebers or with one-piece, shaped according to the respective cross section special knives.

Aus der CN 101200091 B und der US-A-2240765 ist eine gattungsgemäße Pappennutmaschine bekannt, bei der die die Transporttrommel teilweise umschlingenden Riemen über jeweils eine Führungsrolle und mehrere Umlenkwalzen geführt und von separaten Druckrollen gespannt sind. Die mit seitlichen Bordscheiben ausgestatteten Führungsrollen befinden sich auf einer gemeinsamen, wie die Umlenkwalzen im Gestell drehgelagerten Welle und halten die von der Transporttrommel angetriebenen Riemen in bestimmte axiale Positionen zur Transporttrommel, welche durch das Pappenformat und die Lage der zu schneidenden Nuten bestimmt sind.From the CN 101200091 B and the US-A-2240765 a generic cardboard groove machine is known in which the transport drum partially wrapped belt over each guide roller and a plurality of guide rollers and are tensioned by separate pressure rollers. The side flanges equipped with guide pulleys are located on a common, rotatably mounted as the guide rollers in the frame shaft and keep the belt driven by the transport drum in certain axial positions to the transport drum, which are determined by the card size and the position of the grooves to be cut.

Bei einem Umrüstvorgang müssen daher meist auch die Riemen auf andere Positionen verschoben werden. Dies ist jedoch sehr arbeitsintensiv, da zunächst für jeden zu verschiebenden Riemen die zugeordnete Spannrolle außer Eingriff gebracht werden muss, um dann die jeweiligen Führungsrollen auf der Welle zu lösen und stufenweise und abwechselnd mit den Nutenschneidwerkzeugen in die Zielposition zu verschieben, wobei zwischenzeitlich immer wieder die Transporttrommel gedreht werden muss, damit die Riemen nicht zu sehr verschränken. Schließlich müssen die Riemen wieder durch die Spannrollen gespannt werden. Beim Verschieben der Nutenschneidwerkzeuge besteht zudem die Gefahr der Trommelbeschädigung durch die im geringen Abstand zum Trommelmantel stehenden Schneidmesser. Gleiches gilt für die Entnahme oder den Austausch der Nutenschneidwerkzeuge.In a conversion process therefore usually the belt must be moved to other positions. However, this is very labor-intensive, since first for each belt to be moved, the associated tension roller must be disengaged to then release the respective guide rollers on the shaft and gradually and alternately move with the Nutenschneidwerkzeugen to the target position, in the meantime repeatedly Transport drum must be rotated so that the belts do not entangle too much. Finally, the belts must again be tensioned by the tension rollers. When moving the Nutenschneidwerkzeuge also there is a risk of drum damage by standing at a small distance from the drum shell cutting blade. The same applies to the removal or replacement of Nutenschneidwerkzeuge.

Die Aufgabe der Erfindung besteht darin, eine Nutvorrichtung der gattungsgemäßen Art zu schaffen, die sich schnell und einfach auf andere Pappenformate oder sich ändernde Nutlagen umrüsten lässt.The object of the invention is to provide a groove device of the generic type, which can be quickly and easily converted to other board formats or changing groove layers.

Diese Aufgabe wird gelöst durch eine Vorrichtung nach Anspruch 1, oder 2. Die abhängigen Ansprüche definieren bevorzugte Ausführungsformen der erfindungsgemäßen Nutvorrichtung.This object is achieved by a device according to claim 1, or 2. The dependent claims define preferred embodiments of the groove device according to the invention.

Nach der im Anspruch 1 angegebenen Erfindung ist vorgesehen, dass sich die Riemen auf einem radial zur Transporttrommel verschiebbaren, ersten Träger befinden. Der erste Träger kann zwischen einer Arbeitsstellung und einer radial von der Transporttrommel wegbewegten Ruhestellung hin und her geschoben werden. In der Arbeitsstellung sind die in ihrer jeweiligen Position gehaltenen Riemen gespannt, während sie in der Ruhestellung zumindest entspannt und nur noch lose auf der Transporttrommel aufliegen, sodass die jeweiligen Führungs- und Spannrollen mühelos in andere Positionen verschoben werden können. Mit dem Zurückschieben des ersten Trägers in die Arbeitsstellung werden sämtliche Riemen gleichzeitig gespannt und die Nutvorrichtung ist sogleich einsatzbereit.According to the invention specified in claim 1 it is provided that the belt are on a radially displaceable to the transport drum, the first carrier. The first carrier can be pushed back and forth between a working position and a radially away from the transport drum rest position. In the working position, the straps held in their respective position are stretched, while they are at least relaxed in the rest position and rest only loosely on the transport drum, so that the respective guide and tension rollers can be easily moved to other positions. With the pushing back of the first carrier in the working position, all the belts are tensioned simultaneously and the grooving device is immediately ready for use.

Nach der im Nebenanspruch 2 angegebenen Erfindung sind mehrere, separat zueinander und zur Transporttrommel verschiebbare, wenigstens die zur Führung und zum Spannen eines vorzugsweise einzelnen Riemens bestimmten Rollen aufweisende, zweite Träger vorgesehen. Durch die zur Transporttrommel verschiebbaren zweiten Träger werden die Führungs- und Spannrollen des jeweiligen Riemens gemeinsam verschoben. Ihre relative Lage zueinander bleibt bzgl. eines fluchtenden Riemenlaufs und der Riemendehnung unverändert, sodass das zeitaufwendige axiale Einstellen der Führungs- und Spannrollen zueinander entfällt. Der zweite Träger kann radial und/oder axial zur Transporttrommel verschiebbar sein.According to the invention indicated in the independent claim 2, a plurality, separately to each other and the transport drum displaceable, at least provided for guiding and for tensioning a preferably individual belt rollers having, second support provided. By displaceable to the transport drum second carrier the guide and tension rollers of the respective belt are moved together. Their relative position to one another remains unchanged with respect to an aligned belt run and the belt elongation, so that the time-consuming axial adjustment of the guide and tension rollers relative to one another is eliminated. The second carrier may be displaceable radially and / or axially to the transport drum.

In bevorzugter Weiterausgestaltung ist vorgesehen, dass die zweiten Träger axial zur Transporttrommel verschiebbar am ersten Träger angeordnet sind. Die gemeinsame radiale Verschiebung der Riemen wird dabei von dem ersten Träger übernommen. Vorzugsweise sind die zweiten Träger durch Klemmmittel am ersten Träger festlegbar. Denn Klemmmittel lassen sich schnell lösen und aktivieren und ermöglichen eine stufenlose oder gerasterte Positionierung der zweiten Träger respektive Riemen.In a preferred further embodiment, it is provided that the second carrier are arranged axially displaceably on the first carrier to the transport drum. The common radial displacement of the belt is taken over by the first carrier. Preferably, the second carrier can be fixed by clamping means on the first carrier. This is because clamping means can be released and activated quickly and enable stepless or rastered positioning of the second carriers or belts.

In einer Weiterausgestaltung ist vorgesehen, dass am jeweiligen zweiten Träger sämtliche Rollen zur Führung, zur Umlenkung und zum Spannen des vorzugsweise einzelnen Riemens angeordnet sind. Es entfallen die von Gestellwand zu Gestellwand reichenden Umlenkwalzen und ein jeweiliger zweiter Träger kann als Ganzes für Wartungszwecke, bspw. zum Austausch des Riemens aus der Nutvorrichtung entnommen werden.In a further embodiment, it is provided that all rollers for guiding, for deflecting and for tensioning the preferably individual belt are arranged on the respective second carrier. It eliminates the range from frame wall to frame wall-reaching guide rollers and a respective second carrier can be removed as a whole for maintenance purposes, for example, to replace the belt from the groove device.

In einer Weiterausgestaltung ist vorgesehen, dass die zweiten Träger jeweils einen einseitig zum vorzugsweise einzelnen Riemen liegenden Tragarm aufweisen, an dem die Rollen in fliegender Lagerung angeordnet sind. Dadurch lassen sich verschlissene oder beschädigte Riemen sehr leicht austauschen, ohne erst etliche Bauteile entfernen zu müssen.In a further embodiment, it is provided that the second carrier each have a cantilever to one preferably single strap support arm on which the rollers are arranged in flying storage. This makes it easy to replace worn or damaged belts without having to remove a large number of components.

In einer Weiterausgestaltung sind an den zweiten Trägern erste respektive zweite Rollen in einem Abstand vor dem Ein- oder/und Auslauf angeordnet, sodass die Riemen einen tangential zur Transporttrommel zulaufenden respektive von der Transporttrommel ablaufenden Trum aufweisen. Hierdurch kann ein unerwünschter Walk- und Biegeeffekt im Ein- respektive Auslauf deutlich verringert werden und die Pappen werden nahezu planliegend ausgegeben.In a further embodiment, first and second rollers are respectively arranged at a distance in front of the inlet and / or outlet at the second carriers, so that the belts have a tangent to the transport drum respectively running from the transport drum strand. As a result, an unwanted flexing and bending effect in the inlet and outlet can be significantly reduced and the boards are output almost planliegend.

In einer Weiterausgestaltung sind an den zweiten Trägern dritte und vierte Rollen derart angeordnet, dass das Trum zwischen diesen Rollen in einem Abstand von weniger als 10 mm, vorzugsweise weniger als 5 mm, an dem an der Transporttrommel anliegenden Riemenabschnitt vorbei läuft. In diesem Bereich der größten Annäherung können die Nutenschneidwerkzeuge den benachbarten Riemen übergreifen und die eigentlichen Nutmesser können sehr nah zum Riemen positioniert werden, ohne dass die Riemen die Ableitung der anfallenden Späne behindern.In a further embodiment, third and fourth rollers are arranged on the second carriers such that the strand runs between these rollers at a distance of less than 10 mm, preferably less than 5 mm, past the belt section resting against the transport drum. In this area of closest approach, the grooving tools can engage over the adjacent belts and the actual grooving knives can be positioned very close to the belt without the belts hindering the discharge of the resulting shavings.

In einer Weiterausgestaltung ist vorgesehen, dass die Riemen separat kraft- oder wegabhängig gespannt werden, wobei sich die zum Spannen bestimmte Rolle an einem kraftbeaufschlagten, am zweiten Träger beweglich angeordneten Spannhebel befindet bzw. wobei die jeweilige Rolle verschiebbar am zweiten Träger festsetzbar ist. So kann für jeden einzelnen Riemen eine gleiche Riemenspannung abhängig seiner toleranzbehafteten Länge eingestellt werden.In a further embodiment it is provided that the belt force-path-dependent separately or tensioned, with the particular for tensioning roller is located at a force-loaded, movably arranged on the second carrier clamping lever or the respective roll is displaceably securable on the second carrier. Thus, for each individual belt, an equal belt tension can be adjusted depending on its toleranced length.

In einer Weiterausgestaltung ist vorgesehen, dass der erste Träger durch Stellmittel in seiner Position zur Transporttrommel verschiebbar ist. Die Stellmittel können manuell oder motorisch betätigbar sein. Es kann sich um einen Spindel-Mutter-Antrieb handeln oder einen Stellzylinder umfassen. Die Stellmittel erlauben die Positionierung des ersten Trägers in die Arbeitsstellung, die Ruhestellung und ggf. beliebigen Zwischenstellungen. Insbesondere ermöglichen die Stellmittel veränderbare Arbeitsstellungen des ersten Trägers.In a further embodiment, it is provided that the first carrier is displaceable by adjusting means in its position to the transport drum. The adjusting means can be operated manually or by motor. It may be a spindle-nut drive or include a control cylinder. The adjusting means allow the positioning of the first carrier in the working position, the rest position and possibly any intermediate positions. In particular, the adjusting means allow variable working positions of the first carrier.

In einer Weiterausgestaltung ist vorgesehen, dass der erste Träger durch einstellbare Rastmittel in ihrer Arbeitsposition zur Transporttrommel festlegbar sind. Dadurch kann die jeweilige Arbeitsposition schnell und sicher angefahren werden. Durch die Verrastung verändert sich auch unter der Arbeitslast des Nutenschneidens und/oder der Riemenspannung nicht die Arbeitsposition. Mit der Einstellbarkeit der Rastmittel können Grundeinstellungen vorgenommen werden.In a further embodiment, it is provided that the first carrier can be fixed by adjustable latching means in its working position to the transport drum. As a result, the respective working position can be approached quickly and safely. Due to the latching, the working position does not change under the working load of the groove cutting and / or the belt tension. With the adjustability of the locking means basic settings can be made.

In einer Weiterausgestaltung ist am ersten Träger wenigstens eine Skala vorgesehen zur schnellen und reproduzierbaren axialen Positionierung der zweiten Träger zur Transporttrommel.In a further embodiment, at least one scale is provided on the first carrier for rapid and reproducible axial positioning of the second carrier to the transport drum.

In bevorzugter Weiterausgestaltung ist vorgesehen, dass sich sowohl die Riemen als auch die Nutenschneidwerkzeuge auf dem selben radial zur Transporttrommel verschiebbaren ersten Träger befinden. Mit dem Verschieben des ersten Trägers in die Ruhestellung sind die Riemen und gleichzeitig die Nutenschneidwerkzeuge zur axialen Positionsverstellung freigegeben. Mit dem Zurückschieben des gemeinsamen ersten Trägers werden sie simultan in ihre Arbeitsstellungen gebracht.In a preferred refinement, it is provided that both the belts and the groove cutting tools are located on the same first carrier which can be displaced radially relative to the transport drum. With the displacement of the first carrier in the rest position, the belts and at the same time the Nutenschneidwerkzeuge released for axial position adjustment.

Die in Fig. 1 schematisch dargestellte Nutvorrichtung 1 besteht im Wesentlichen aus einer angetriebenen, liegend gelagerten Transporttrommel 11 und mehreren, endlos um Rollen 54.1 bis 54.8 umlaufenden und zueinander beabstandeten, die Transporttrommel 11 unter Ausbildung eines Einlaufs 14 und eines Auslaufs 15 teilweise umschlingenden Riemen 51 sowie zwischen den Riemen 51 in einem definierten Abstand von dem Trommelmantel angeordneten Nutenschneidwerkzeugen 72. Von einer Zuführeinrichtung 101 dem Einlauf 14 zugeführte Pappenzuschnitte 2 werden von den Riemen 51 förderwirksam auf den Trommelmantel gedrückt und in Transportrichtung 11a in einer etwa 180° Drehung der Transporttrommel 11 vom im unteren Scheitelpunkt der Transporttrommel 11 liegenden Einlauf 14 zum im oberen Scheitelpunkt liegenden Auslauf 15 gefördert und dabei an den Nutenschneidwerkzeugen 72 vorbeigeführt, wo mit entsprechend gestalteten Nutmessern 71 ein beispielsweise V-förmiger Span 6 aus den Pappenzuschnitten 2 herausgeschnitten wird.In the Fig. 1 1 schematically shown groove device 1 consists essentially of a driven, horizontally mounted transport drum 11 and a plurality of endlessly around rollers 54.1 to 54.8 rotating and spaced, the transport drum 11 to form an inlet 14 and a spout 15 partially wrap around belt 51 and between the belt 51st Nutenschneidwerkzeugen 72 arranged at a defined distance from the drum shell. From a feeder 101 the inlet 14 supplied cardboard blanks 2 are conveyed by the belt 51 promoting effect on the drum shell and in the transport direction 11a in an approximately 180 ° rotation of the transport drum 11 from the lower vertex of the transport drum 11 lying inlet 14 for lying in the upper vertex outlet 15 promoted and passed past the Nutenschneidwerkzeugen 72 where herausgesc with appropriately shaped slot knives 71, for example, a V-shaped chip 6 from the cardboard blank 2 is cut.

Die Zuführeinrichtung 101 in Fig. 1 weist ein ergonomisch günstig zu befüllendes Pappenmagazin 102 auf, das einen Stapel 4 von übereinander liegenden Pappenzuschnitten enthält. Der jeweils unterste Pappenzuschnitt 2 wird von einem ersten Pappenschieber 104.1 unter einen vorderen Anschlag 103 ausgeschoben und zu einer Zwischenposition 105 überführt, aus der der Pappenzuschnitt 2 mit einem zweiten Pappenschieber 104.2 unter Ausrichtung an äußeren Führungsschienen 106 dem Einlauf 14 zugeführt wird. Die Pappenschieber 104.1, 104.2 sind in einem festen Abstand miteinander gekoppelt und werden mit einem konstanten Förderhub 107 gleich diesem Abstand taktgemäß vor und zurück bewegt. Die Zuführgeschwindigkeit liegt dabei etwas über der Drehgeschwindigkeit der Transporttrommel 11, sodass die Pappenzuschnitte 2 quasi zwangsweise in den Einlauf 14 zwischen Transporttrommel 11 und Riemen 51 eingeschoben werden.The feeder 101 in Fig. 1 has an ergonomically favorable to be filled cardboard magazine 102, which contains a stack 4 of superimposed cardboard blank. The respective lowermost cardboard blank 2 is pushed out by a first board slider 104.1 under a front stop 103 and transferred to an intermediate position 105, from which the board blank 2 is fed to the inlet 14 with a second board slider 104.2 aligned with outer guide rails 106. The board slides 104.1, 104.2 are coupled together at a fixed distance and are moved in a constant delivery stroke 107 equal to this distance clockwise back and forth. The feed rate is slightly above the rotational speed the transport drum 11, so that the cardboard blanks 2 quasi forcibly inserted into the inlet 14 between the transport drum 11 and belt 51.

Durch die Anordnung der Rollen 54.2 in einem Abstand vor dem Einlauf 14 weisen die Riemen 51 einen tangential zur Transporttrommel 11 zulaufenden Trum auf. Das Walken und Biegen im Einlauf 14 ist dadurch deutlich reduziert. Weiter unterstützt das Trum die Ausrichtung der Pappenzuschnitte 2 an den etwas schneller laufenden Pappenschiebern 104.2 der Zuführeinrichtung 101.Due to the arrangement of the rollers 54.2 at a distance in front of the inlet 14, the belts 51 have a tangent to the transport drum 11 tapered strand. The walking and bending in the inlet 14 is thereby significantly reduced. Furthermore, the strand supports the orientation of the cardboard blanks 2 on the somewhat faster cardboard sliders 104.2 of the feeder 101.

Die Ausfuhr 111 in Fig. 1 weist einen schräg nach vorn abfallenden Auslagetisch 112 auf, auf den die aus dem Auslauf 15 auslaufenden, fertig genuteten Pappenzuschnitte 3 abgeworfen und zum Stapel 5 übereinander gelegt werden. Durch die Anordnung des Auslaufs 15 im oberen Scheitelpunkt der Transporttrommel 11 liegen die geschnittenen Nuten 3a in den auslaufenden Pappenzuschnitten 3 oben. Dadurch sind während des Betriebs die geschnittenen Nuten 3a von oben einsehbar und die Nutqualität kann ohne Entnahme von einzelnen Pappenzuschnitten 3 fortlaufend an jeder ausgegebenen Pappe beurteilt werden. Mit der Ausgabe der genuteten Pappenzuschnitte 3 am oberen Scheitelpunkt der Transporttrommel 11 und der Ablage auf dem tiefer liegenden Auslagetisch 112 ergibt sich zudem eine ergonomisch günstige Abnahmehöhe.The export 111 in Fig. 1 has an obliquely sloping forward delivery table 112 to which the expiring from the outlet 15, finished grooved cardboard cuttings 3 are dropped and stacked to stack 5. Due to the arrangement of the outlet 15 in the upper vertex of the transport drum 11, the cut grooves 3a are in the expiring cardboard blank 3 above. As a result, the cut grooves 3a are visible from above during operation and the groove quality can be assessed without removing individual cardboard blank 3 continuously on each output cardboard. With the output of the grooved cardboard cuttings 3 at the upper vertex of the transport drum 11 and the tray on the lower-lying delivery table 112 also results in an ergonomically favorable take-off height.

Durch die Anordnung der Rollen 54.1 in einem Abstand vor dem Auslauf 15 weisen die Riemen 51 einen tangential von der Transporttrommel 11 ablaufenden Trum auf. Das Walken und Biegen im Auslauf 15 ist dadurch deutlich reduziert und die genuteten Pappenzuschnitte 3 werden nahezu planliegend ausgegeben.Due to the arrangement of the rollers 54.1 at a distance in front of the outlet 15, the belts 51 have a run tangentially from the transport drum 11 run. The walking and bending in the outlet 15 is thereby significantly reduced and the grooved cardboard blanks 3 are issued almost planliegend.

Die Ausfuhr 111 und die Zuführeinrichtung 101 liegen auf der gleichen Seite der Transporttrommel 11, der sogenannten Bedienseite 66, während sich die Nutenschneidwerkzeuge 72 frei zugänglich auf der gegenüberliegenden Werkzeugseite 67 befinden.The export 111 and the feed device 101 are located on the same side of the transport drum 11, the so-called operating side 66, while the Nutenschneidwerkzeuge 72 are freely accessible on the opposite tool side 67.
