Abstract

The two cutter beams (1,2) are driven on circular paths in synchronism and in opposite directions by cranks (3-6) at their ends, while other cranks (16,17) also driven in synchronism, keep them in parallel positions. Each cutter beam has only one additional crank, which supports it at the middle.The cutter beams are located one above the other,and the cranks are mounted in stands(7,8)of the machine frame.The crank drive has meshing gears(9-12). USE/ADVANTAGE - For transverse cutting shears,with relatively low inertial mass.

Description

Die Erfindung bezieht sich auf eine Querteilschere für durchlaufendes Bandmaterial mit zwei synchron auf Kreisbahnen gegensinnig angetriebenen Messerbalken, die an ihren Enden von Kurbeln gehalten sind, wobei an den Messerbalken weitere synchron angetriebene Kurbeln als Führung derart angreifen, daß die Messerbalken zu sich selbst parallel geführt werden.The invention relates to a cross cutting shear for continuous strip material with two synchronously on circular paths oppositely driven cutter bars, which are held at their ends by cranks, with more on the cutter bars synchronously driven cranks as a guide attack that the cutter bar is parallel to itself be performed.

Querteilscheren dieser Art sind bekannt (US 19 13 153; EP 02 28 517 B1). Bei diesen Querteilscheren bewegen sich die Messerbalken während des Schnittes nicht nur aufeinander zu, sondern auch in Bandlaufrichtung, weil sie über Kurbeln auf einer Kreisbahn umlaufen. Zum Zwecke der Parallelführung eines jeden Messerbalkens ist jedem Messerbalken ein weiteres Kurbelpaar zugeordnet. Die weiteren nur für die Parallelführung benötigten Kurbeln und ihre Lagerungen und Antriebsmittel machen einen großen Teil der trägen Masse der Querteilschere aus. Ein weiterer erheblicher Anteil an der trägen Masse der Querteilschere ergibt sich aus der für eine hohe Biegesteifigkeit der Messerbalken notwendigen Konstruktion der Messerbalken.Cross cutting scissors of this type are known (US 19 13 153; EP 02 28 517 B1). These cross cut shears move the cutter bars not only during the cut towards each other, but also in the direction of tape travel, because they circulate on cranks on a circular path. For the purpose of Every knife beam is parallel to everyone Knife bar assigned another pair of cranks. The others only required for the parallel guide and their cranks Bearings and drive means make up a large part the inertial mass of the cross-cut shears. Another considerable proportion of the inertial mass of the cross-cut shears results from the for a high bending stiffness Knife bar necessary construction of the knife bar.

Der Erfindung liegt die Aufgabe zugrunde, eine in der Konstruktion einfache Querteilschere mit einer im Vergleich zu herkömmlichen Querteilscheren kleinen trägen Masse zu schafffen.The invention is based, one in the task  Construction of simple cross-cut shears with an Smaller compared to conventional cross-cut shears create inert mass.

Diese Aufgabe wird bei einer Querteilschere der eingangs genannten Art dadurch gelöst, daß jedem Messerbalken nur eine weitere Kurbel als Parallelführung zugeordnet ist und daß diese weitere Kurbel den Messerbalken in seinem Mittenbereich abstützt.This task is at the beginning of a transverse shear mentioned type solved in that each cutter bar only one additional crank is assigned as a parallel guide is and that this further crank the cutter bar in supports its central area.

Bei der Erfindung wird gleich aus zwei Gründen die träge Masse verkleinert, nämlich einmal dadurch, daß für die Parallelführung eines jeden Messerbalkens nur eine weitere Kurbel eingesetzt wird und zum anderen dadurch, daß nicht die Konstruktion des Messerbalkens selbst biegesteifer gemacht ist, sondern daß der Messerbalken durch die ohnehin notwendige weitere Kurbel abgestützt wird. Deshalb ist die Querteilschere für hohe Bandgeschwindigkeiten bei kleinen Abschnittlängen einsetzbar. Da die weitere Kurbel im Mittenbereich am Messerbalken angreift, ergibt sich ein symmetrischer und zum gegenüberliegenden Messerbalken synchroner Antrieb des jeweiligen Messerbalkens.The invention becomes sluggish for two reasons Reduced mass, namely once that for the Parallel guidance of each cutter bar only one additional crank is used and secondly because that not the construction of the cutter bar itself is made more rigid, but that the cutter bar supported by the additional crank that is necessary anyway becomes. That is why the cross-cut shear is for high Belt speeds with small section lengths applicable. Since the other crank in the middle area on Knife bar attacks, there is a symmetrical and synchronized with the opposite knife bar Drive of the respective cutter bar.

Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert, die eine erfindungsgemäße Querteilschere in Ansicht zeigt.In the following the invention with reference to a drawing explained in more detail that an inventive Cross cut shear in view shows.

Ein oberer Messerbalken 1 und ein unterer Messerbalken 2 sind an ihren Enden von Kurbeln 3-6 getragen. Die Kurbeln 3-6 sind in Ständern 7, 8 des Maschinengestells gelagert. Die Kurbeln 3, 5 beziehungsweise 4, 6 sind getriebemäßig über im Eingriff stehende Zahnräder 9, 10 beziehungsweise 11, 12 starr drehfest gekoppelt. Eines der Zahnräder 9, 10 steht mit einem in der Zeichnung nicht dargestellten Zahnrad im Eingriff, das gegebenenfalls über ein Getriebe von einem Motor 13 angetrieben ist. Das Zahnrad 12 steht mit einem Zahnrad 14 im Eingriff, das über eine Welle 15 in einer der Zeichnung nicht dargestellten Weise mit dem Motor 13 verbunden ist.An upper cutter bar 1 and a lower knife beams 2 are connected at their ends by cranks 3 - worn. 6 The cranks 3 - 6 are mounted in stands 7 , 8 of the machine frame. The cranks 3 , 5 and 4 , 6 are rigidly coupled in a rotationally fixed manner via gearwheels 9 , 10 and 11 , 12 which are in engagement. One of the gear wheels 9 , 10 is in engagement with a gear wheel, not shown in the drawing, which is possibly driven by a motor 13 via a gear. The gear 12 is in engagement with a gear 14 which is connected to the motor 13 via a shaft 15 in a manner not shown in the drawing.

Jedem Messerbalken 1, 2 ist in seiner Mittel eine weitere Kurbel 16, 17 zugeordnet, die über ein starr an dem Messerbalken 1, 2 angebrachtes Stütz- und Führungselement 18, 19 an dem Messerbalken 1, 2 angreift. Die Kurbel 16, 17 ist in einem am Maschinengestell gehaltenen Lagerbock 20, 21 mit einer Antriebswelle 22, 23 gelagert, die ihrerseits über ein Antriebselement, vorzugsweise einen Zahnriemen 24, 25, mit einer Antriebswelle 26, 27, auf der die Kurbeln 3, 5 und die Zahnräder 9, 10 sitzen, angetrieben ist.Each cutter bar 1, 2 is in its center a further crank 16, 17 is assigned, via a rigidly to the cutter bar 1, 2 mounted supporting and guiding element 18 acts on the cutter bar 1, 2 nineteenth The crank 16 , 17 is mounted in a bearing block 20 , 21 held on the machine frame with a drive shaft 22 , 23 , which in turn has a drive element 26 , 27 , via a drive element, preferably a toothed belt 24 , 25 , on which the cranks 3 , 5 and the gears 9 , 10 are seated, driven.
