Abstract
Vorrichtung zum exakten Schneiden von Ausnehmungen in Bögen, Bahnen oder dergleichen aus Wellpappe, insbesondere Schwerwellpappe, dadurch gekennzeichnet, dass zwei miteinander zusammenwirkende Kreismesser (12, 13), die im Winkel (α) der zu erstellenden keilförmigen Ausnehmungen (14) zueinander angeordnet sind, einen gemeinsamen Antrieb (25) aufweisen, und dass die Umfangsgeschwindigkeit der beiden Kreismesser (12, 13) größer ist als die Transportgeschwindigkeit der durchlaufenden Bahn.Device for the exact cutting of recesses in sheets, webs or the like from corrugated cardboard, in particular heavy corrugated cardboard, characterized in that two interacting circular knives (12, 13), which are arranged at an angle (α) of the wedge-shaped recesses (14) to be produced, have a common drive (25) and that the peripheral speed of the two circular knives (12, 13) is greater than the transport speed of the continuous web.
Description
Die Erfindung betrifft Vorrichtungen nach dem Oberbegriff des Anspruches 1.The invention relates to devices according to the preamble of claim 1.
Wellpappebögen oder -bahnen bzw. Bögen oder Bahnen aus Kunststoff, laminiertem Papier oder dergleichen, zur Herstellung von Behältern, Schachteln usw. werden in der Regel mit Hilfe von Längsrillen gerillt und anschließend in einem weiteren Bearbeitungsschritt längs dieser Kanten abgewinkelt. Mehrere auf diese Weise gekantete Bögen bilden miteinander den fertigen Behälter. Derartige Längsrillen haben den Nachteil, dass insbesondere bei Schwerwellpappe, wie z. B. Dreifach- oder Vierfach-Wellpappe; die Rillungen nicht mehr ausreichend effektiv ausgeführt werden können, da die innere Steifigkeit der einzelnen, zusammen verklebten Wellpappenpapiere sehr hoch ist. Dies führt bei einem anschließenden Abkanten der Bögen zu ungenauen Kanten. Beim Übereinanderstapeln mehrerer derartiger Wellpappenbehälter bzw. – kisten führt eine ungenaue Kantung zu einer schlechten Stapelqualität, d. h. dass aufgrund der unterschiedlichen Höhen der einzelnen Behälter ein schiefer Stapel entsteht, der in extremen Fällen sogar kippen kann.Corrugated cardboard sheets or sheets or sheets or Sheets of plastic, laminated paper or the like, for Manufacture of containers, Boxes etc. are usually made using longitudinal grooves grooved and then angled along these edges in a further processing step. Several sheets bent in this way together form the finished container. Such longitudinal grooves have the disadvantage that especially with heavy corrugated cardboard such. B. triple or quadruple corrugated cardboard; the creases are no longer sufficiently effective can, because the inner stiffness of the individual corrugated papers glued together is very high. this leads to with a subsequent one Bending the arches to inaccurate edges. When stacking on top of each other Several such corrugated cardboard containers or crates lead to an imprecise edging poor stack quality, d. H. that due to the different heights of each container skewed pile is created, which can even tip in extreme cases.

Des weiteren betrifft die
Des weiteren ist aus der
Aufgabe der Erfindung ist, eine gattungsgemäße Vorrichtung so weiter zu entwickeln, dass das Abkanten von Bögen oder Bahnen aus Wellpappe oder vergleichbarem Material, vorzugsweise Schwer- und Schwerst-Wellpappe, entlang einer genau definierten Linie unter Einhaltung extrem geringer Toleranzen mit hoher Schnittqualität an den Schnittkanten vorgenommen werden kann.The object of the invention is a generic device to develop further so that the folding of sheets or sheets of corrugated cardboard or comparable material, preferably heavy and heavy corrugated cardboard, along a precisely defined line while maintaining extremely low Tolerances with high cut quality made at the cut edges can be.
Gemäß der Erfindung wird diese Aufgabe mit den Merkmalen des Kennzeichens des Anspruches 1 gelöst. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.According to the invention, this is Object achieved with the features of the characterizing part of claim 1. Further Embodiments of the invention are the subject of the dependent claims.
Mit der Erfindung wird somit vorgeschlagen, keilförmige Ausnehmungen in Form von linienförmigen Vertiefungen aus Bögen oder Bahnen, z. B. aus Wellpappe, herauszuschneiden, wobei diese keilförmigen Linien den Rill-Linien herkömmlicher Wellpappe bögen entsprechen. Die keilförmigen Ausnehmungen können durch unterschiedliches Anstellen der beiden miteinander zusammenwirkenden Schneidmesser im Öffnungs winkel verändert werden, so dass die Keilwinkel je nach dem Einsatzzweck der Wellpappebögen spitzwinklig, rechtwinklig oder auch stumpfwinklig sein können. Durch das Herausschneiden derartiger Keile lassen sich die Wellpappebögen längs dieser exakten Schwächungslinien genau definiert abknicken, so dass insbesondere bei Schwerwellpappe, wie z.B. Dreifach- oder Vierfach-Wellpappe, eine exakte und einwandfreie Rillung erzielt wird, mit der es möglich ist, Wellpappebehälter sehr genau definiert zu kanten.The invention thus proposes wedge-shaped recesses in the form of line-shaped Wells from arches or webs, e.g. B. from corrugated cardboard, this wedge-shaped Lines the creasing lines more conventional Corrugated cardboard sheets correspond. The wedge-shaped Recesses can by differently positioning the two interacting cutting knives in the opening angle changed so that the wedge angles are acute depending on the purpose of the corrugated cardboard sheets, can be rectangular or obtuse. By cutting out Such wedges allow the corrugated cardboard sheets to be made along these exact lines of weakness kink exactly defined, so that especially with heavy corrugated cardboard, such as. Triple or quadruple corrugated cardboard, an exact and flawless Creasing is achieved with which it is possible to use corrugated containers very much edging exactly defined.
Die beiden miteinander zusammenwirkenden Schneidmesser sind vorzugsweise scheibenförmige Schneidmesser, die beide die keilförmige Rinne ausbilden und die in ihrer Winkelposition zueinander verstellbar sowie in ihrer Ebene auf die keilförmige Rille zu einstellbar sind. Die beiden dünnen Kreismesser werden jeweils über Riemen z.B. Zahnriemen, Gelenkwellen und dgl. über eine gemeinsame Antriebswelle angetrieben, so dass nur ein einziger Antriebsmotor vorgesehen ist. Die zu schneidende Wellpappe wird mit Hilfe von einstellbaren Niederhaltern in der für den Schneidvorgang erforderlichen definierten Position gehalten; dies wird durch die den Schneidmessern vor- und nachgeschalteten Einzugs- und Auszugswalzen unterstützt. Die seitliche Führung des Wellpappebogens geschieht in herkömmlicher Weise mittels einstellbarer Führungswinkel.The two interacting with each other Cutting knives are preferred disc-shaped cutting knife, both of which are wedge-shaped Form gutter and adjustable in their angular position to each other as well as adjustable in their level to the wedge-shaped groove are. The two thin ones Circular knives are each over Straps e.g. Toothed belts, cardan shafts and the like via a common drive shaft driven so that only a single drive motor is provided. The corrugated cardboard to be cut is made using adjustable hold-down devices in the for held the defined position required for the cutting process; this is done upstream and downstream of the cutting blades Infeed and outfeed rollers supported. The lateral guidance of the Corrugated cardboard sheet is done in a conventional manner by means of adjustable Guide angle.
Damit die Schneidmesser während des Betriebes nachgeschliffen werden können, sind sie vorzugsweise außen glatt, d.h. unverzahnt ausgebildet.So that the cutting knife during the Operation can be reground, they are preferred Outside smooth, i.e. trained without teeth.
Nachstehend wird die Erfindung in Verbindung mit der Zeichnung anhand eines Ausführungsbeispieles erläutert. Es zeigt:The invention is hereinafter described in Connection with the drawing explained using an exemplary embodiment. It shows:
