Abstract

The corrugation process imprints transverse corrugations in endless webs of card, particularly multilaminar corrugated card with cover papers on both sides. Both sides of the foldable material are deformed by corrugating rolls (1, 2) carrying corrugating tools (11, 12, 21, 22). The spacing of two grooves on opposite sides corresponds to the fold length of the material.

Description

Die Erfindung betrifft eine Vorrichtung zum Einprägen von Querrillen in faltbare Materialien, insbesondere Pappe, insbesondere Endlosbahnen aus Pappe, insbesondere ein- oder mehrwellige Wellpappe mit beidseitigen Deckpapieren, wobei zur Herstellung einer Rille beide Seiten des faltbaren Materials von Werkzeugen verformt werden, gemäß des Oberbegriffs nach Anspruch 1. Eine derartige Vorrichtung ist aus der US 3,647,201 bekannt.The invention relates to a device for embossing transverse grooves in foldable materials, in particular cardboard, in particular continuous webs of cardboard, in particular single- or multi-wall corrugated board with double-sided cover papers, wherein both sides of the foldable material of tools are deformed for producing a groove, according to the preamble Claim 1. Such a device is known from US 3,647,201 known.

Endlosbahnen aus faltbaren Materialien, die jedoch aufgrund ihrer Materialeigenschaften nicht biegsam sind, d.h. sich nicht ohne Beschädigung auf einer Rolle aufrollen lassen, wie z.B. ein- oder mehrlagige Wellpappen mit beidseitigen Deckpapieren, werden in Form der Leporellofaltung zusammengelegt.Continuous webs of foldable materials, but not flexible due to their material properties, i. can not be rolled on a roll without damage, e.g. single- or multi-ply corrugated board with double-sided cover papers are combined in the form of Leporellofaltung.

Nach dem Stand der Technik wird zur Erzeugung einer Leporellofaltung das Material in äquidistanten Abständen, die der Faltlänge entsprechen, quer gerillt. Die eingeprägten Querrillen dienen als Faltlinie. Die Rillung erfolgt in der Weise, dass beispielsweise mittels eines periodisch arbeitenden Schlagwerkzeuges, die Rillen eingeprägt werden. Diese Rillung erfolgt nach dem Stand der Technik lediglich von einer Seite der Bahn, so dass bei der Erzeugung einer Leporellofaltung jede zweite Faltung gegen die Orientierung der Rillung erfolgt. Dies führt zu Ungenauigkeiten bei der Leporellofaltung und zu unsauber gestapelten Faltungen.According to the prior art, the material is grooved transversely at equidistant intervals corresponding to the fold length in order to produce a fan-fold. The embossed transverse grooves serve as folding line. The creasing takes place in such a way that, for example by means of a periodically operating impact tool, the grooves are impressed. This creasing is carried out according to the prior art only from one side of the web, so that when creating a Leporellofaltung every second convolution takes place against the orientation of the crease. This leads to inaccuracies in the Leporellofaltung and improperly stacked folds.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art bereitzustellen, wobei das zu einer Leporellofaltung zusammen zu legende Material in der Weise von beiden Seiten gerillt wird, dass eine Leporellofaltung jeweils entsprechend der Orientierung der Rillung und damit mit hoher Genauigkeit und mit hoher Flexibilität erfolgen kann.The object of the invention is to provide a device of the type mentioned above, wherein the Leporellofaltung to be laid together material is grooved in such a way from both sides that a Leporellofaltung respectively according to the orientation of the groove and thus with high accuracy and high flexibility can be done.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gemäß Anspruch 1 gelöst.This object is achieved by a device according to claim 1.

Das Zusammenlegen dieser Bahnen in Form einer Leporellofaltung kann so mit großer Genauigkeit erfolgen, da alle Faltungen entsprechend der Orientierung der jeweiligen Rillung erfolgen.The collapsing of these webs in the form of a Leporellofaltung can be done with great accuracy, since all folds are made according to the orientation of the respective grooving.

Vorzugsweise arbeitet die Vorrichtung kontinuierlich während eines kontinuierlichen Vorschubs der zu rillenden Bahn.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen aufgeführt.Preferably, the device operates continuously during a continuous advance of the web to be corrugated.
Advantageous embodiments of the invention are listed in the subclaims.

In Figur 1 näher sind zwei gegenläufig rotierende Rillwalzen (1, 2) mit zumindest je einem positiven und einem negativen Rillwerkzeug (11, 12 bzw. 21, 22), die auf dem Umfang einer jeden Rillwalze (1, 2) angeordnet sind, dargestellt. Die gegenläufige Rotation der Walzen (1, 2) erfolgt synchronisiert, so dass jeweils ein positives Rillwerkzeug (11, 21) der einen Walze gleichzeitig mit einem negativen Rillwerkzeug (12, 22) der anderen Walze das zwischen den Walzen hindurchgeführte Material rillt. Die Bahnlänge des Umfangsversatzes der Rillwerkzeuge auf den beiden Walzen entspricht dem gewünschten Teilungsabstand der Rillung des faltbaren Matrials, d.h. der gewünschten Faltlänge.In FIG. 1 closer are two counter-rotating creasing rollers (1, 2) with at least one positive and one negative creasing tool (11, 12 or 21, 22), which are arranged on the circumference of each creasing roller (1, 2). The opposite rotation of the rollers (1, 2) is synchronized, so that in each case a positive scoring tool (11, 21) of the one roller simultaneously with a negative scoring tool (12, 22) of the other roller grooves the material passed between the rollers. The path length of the circumferential offset of the scoring tools on the two rollers corresponds to the desired pitch of the scoring of the foldable Matrials, ie the desired folding length.

Bei den genannten negativen Rillwerkzeugen (12, 22) kann es sich auch um eine glatte Oberfläche handeln, beispielsweise die Oberfläche einer nicht konturierten Walze oder einer Platte, die als Gegenstück zu den positiven Rillwerkzeugen (11, 21) wirkt. Vorzugsweise handelt es sich jedoch bei den negativen Rillwerkzeugen (12, 22) um negative Matrizen, die die exakten Gegenstücke zu positiven Matrizen der positiven Rillwerkzeuge (11, 21) bilden.The mentioned negative scoring tools (12, 22) can also be a smooth surface, for example the surface of a non-contoured roller or a plate, which acts as a counterpart to the positive scoring tools (11, 21). However, the negative scoring tools (12, 22) are preferably negative matrices which form the exact counterparts to positive matrices of the positive scoring tools (11, 21).

Bei der hier gezeigten Ausführungsform ist der Radius der Rillwerkzeuge (11, 12, 21, 22) auf den Rillwalzen (1, 2) variabel und beliebig einstellbar, angedeutet durch drei Kreise (60, 61, 62). Die radiale Einstellbarkeit der Rillwerkzeuge (11, 12, 21, 22) auf den Walzen (1, 2) ist jedoch nicht auf diese drei Positionen (60, 61, 62) beschränkt, vielmehr handelt es sich nur um Beispiele. Diese vorteilhafte Ausgestaltung ermöglicht eine beliebige Einstellung des Umfangsversatzes und damit des Teilungsabstandes der Rillung.In the embodiment shown here, the radius of the scoring tools (11, 12, 21, 22) on the creasing rollers (1, 2) is variable and arbitrarily adjustable, indicated by three circles (60, 61, 62). However, the radial adjustability of the scoring tools (11, 12, 21, 22) on the rollers (1, 2) is not limited to these three positions (60, 61, 62), but only examples. This advantageous embodiment allows any adjustment of the circumferential offset and thus the pitch of the groove.

Ebenfalls variabel ist der Achsabstand der beiden Rillwalzen (1, 2), um unterschiedliche Radien der Rillwerkzeuge (11, 12, 21, 22) einstellen bzw. Materialien unterschiedlicher Dicke bearbeiten zu können.Also variable is the center distance of the two creasing rollers (1, 2) to set different radii of the creasing tools (11, 12, 21, 22) or to edit materials of different thicknesses.

Die Einstellung unterschiedlicher Radien erfolgt über eine radiale Verschiebung der Rillwerkzeugträger (101, 102, 201, 202) auf den Walzen (1, 2). Die positiven und negativen Rillwerkzeuge (11, 12, 21, 22) sind auf den Rillwerkzeugträgern (101, 102, 201, 202) austauschbar montiert, Rillwerkzeuge und Rillwerkzeugträger können jedoch alternativ einteilig ausgeführt sein.The setting of different radii via a radial displacement of the Rillwerkzeugträger (101, 102, 201, 202) on the rollers (1, 2). The positive and negative scoring tools (11, 12, 21, 22) are interchangeably mounted on the grooved tool carriers (101, 102, 201, 202), however, scoring tools and grooved tool carriers may alternatively be made in one piece.

Die radiale Verstellung der Rillwerkzeugträger (101, 102, 201, 202) kann mittels Zahnstangen oder Zahnstangensegmenten oder alternativ mittels Gewindespindeln erfolgen. Eine besonders vorteilhafte Ausgestaltung der Rillwerkzeugträger (101, 102, 201, 202) ist in Figur 1 dargestellt. Es handelt sich bei den Rillwerkzeugträgern um L-förmige Werkzeugträger. Der Grundkörper der Rillwalzen (1, 2) ist zwischen den Wellenzapfen rechteckig ausgeführt und verfügt über Aufnahmen für die Werkzeugträger sowie über Zahnstangen zur radialen Verschiebung der Werkzeugträger. Zur Fixierung der Werkzeugträger (101, 102, 201, 202) in der gewünschten radialen Position sind keilförmig ausgebildete Klemmplatten vorgesehen, die in Richtung der Achse der Walzen (1, 2) verschiebbar angeordnet sind. Die L-förmigen Werkzeugträger sind paarweise gegenüberliegend auf den Walzen (1, 2) angeordnet. Es kann eine beliebige Anzahl von Werkzeugträgerpaaren angeordnet sein, die abwechselnd positive und negative Rillwerkzeuge tragen.The radial adjustment of the Rillwerkzeugträger (101, 102, 201, 202) can be done by means of racks or rack segments or alternatively by means of threaded spindles. A particularly advantageous embodiment of the Rillwerkzeugträger (101, 102, 201, 202) is in FIG. 1 shown. These are the grooved tool carriers around L-shaped tool carrier. The main body of the creasing rollers (1, 2) is rectangular between the shaft journals and has receptacles for the tool carrier and racks for radial displacement of the tool carrier. For fixing the tool carriers (101, 102, 201, 202) in the desired radial position wedge-shaped clamping plates are provided, which are arranged displaceably in the direction of the axis of the rollers (1, 2). The L-shaped tool carriers are arranged in pairs opposite one another on the rollers (1, 2). There may be arranged any number of tool carrier pairs, which alternately carry positive and negative scoring tools.

Eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung ist in Figur 2 dargestellt. Die Rillwalzen (1, 2) sind an scherenförmig angeordneten Armen gelagert, deren Öffnungswinkel (α) variabel ist. Die Öffnung und Schließung der scherenförmigen Arme und damit die Variation des Achsabstandes der Walzen (1, 2) erfolgt mittels zumindest einer Gewindespindel (5).Another embodiment of the device according to the invention is in FIG. 2 shown. The creasing rollers (1, 2) are mounted on scissors-shaped arms whose opening angle (α) is variable. The opening and closing of the scissor-shaped arms and thus the variation of the axial distance of the rollers (1, 2) by means of at least one threaded spindle (5).

Alternativ kann die Öffnung der Arme auch durch Zahnstangen oder mittels Hydraulik erfolgen. Die Synchronisierung der Rillwalzen (1, 2) erfolgt vorzugsweise mittels elektronischer Kopplung der Antriebsmittel der Körper (1, 2) und/oder mittels Stirnrädern (31, 32, 41, 42).Alternatively, the opening of the arms can also be done by racks or by hydraulic means. The synchronization of the creasing rollers (1, 2) is preferably carried out by means of electronic coupling of the drive means of the body (1, 2) and / or by means of spur gears (31, 32, 41, 42).

Zusätzlich zu den Walzen (1, 2), die die Rillwerkzeuge tragen, können Vorschubwalzen zum kontinuierlichen Vorschub des zu rillenden Materials vorgesehen sein. Vorzugsweise sind die Rotation der Rillwalzen (1, 2) und der Vorschubwalzen synchronisiert bzw. bei unterschiedlichen Durchmessern entsprechend auf die selbe Bahngeschwindigkeit abgestimmt. Die Synchronisierung oder Abstimmung der Rillwalzen (1, 2) und der Vorschubwalzen erfolgt vorzugsweise durch elektronische Kopplung der Antriebsmittel der Rillwalzen (1, 2) und der Vorschubwalzen und/oder mittels Stirnrädern. Der Achsabstand der zusätzlichen Vorschubwalzen kann variabel sein, um Materialien unterschiedlicher Stärke bearbeiten zu können.In addition to the rollers (1, 2) carrying the scoring tools, feed rollers may be provided for the continuous advancement of the material to be scored. Preferably, the rotation of the creasing rollers (1, 2) and the feed rollers are synchronized or tuned at different diameters according to the same web speed. The synchronization or tuning of the creasing rollers (1, 2) and the feed rollers is preferably carried out by electronic coupling of the drive means of the creasing rollers (1, 2) and the feed rollers and / or by means of spur gears. The center distance of the additional feed rollers may be variable in order to process materials of different thickness.
