Description

Die Erfindung betrifft eine Dreimesserschneidemaschine, mit einem Frontmesser und zwei Seitenmessern, die von einer Antriebsvorrichtung so angetrieben sind, dass sie phasenverschoben an einem Schneidgut einen Frontschnitt und wenigstens einen Seitenschnitt durchführen.The invention relates to a three-knife cutting machine, with a front knife and two side knives by a drive device are driven to be out of phase on a cut, a front cut and at least one Carry out a side cut.

Dreimesserschneidemaschinen zum dreiseitigen Beschneiden von Druckprodukten, beispielsweise Büchern, Broschüren und dergleichen sind seit langem bekannt. Das Schneidgut wird zum Schneiden auf einen Schneidetisch befördert und auf diesem unter den Messern ausgerichtet sowie von einer Pressplatte oder dergleichen auf dem Schneidetisch festgehalten. Mit den beiden Seitenmessern wird gleichzeitig die Kopf- und die Fussseite des Schneidgutes beschnitten. Zuvor oder anschliessend erfolgt in einem weiteren Arbeitsgang mit dem Frontmesser der Schnitt der Vorderseite. Das beschnittene Schneidgut wird automatisch aus dem Schneidbereich herausbewegt und beispielsweise mittels eines Förderbandes aus der Dreischneidemaschine abgeführt. Bei diesen Dreimesserschneidemaschinen erfolgen die Schnitte somit in einer einzigen Schneidestation. Da das Schneidgut lediglich einmal ausgerichtet werden muss, ergeben sich wesentliche Vorteile gegenüber Dreimesserschneidemaschinen mit zwei Stationen. Damit Front- und Seitenmesser nicht kollidieren, werden Frontschnitt und Seitenschnitt phasenverschoben durchgeführt.Three knife cutting machines for three sided trimming of Printed products such as books, brochures and the like have been known for a long time. The material to be cut becomes Cutting is conveyed to and on a cutting table aligned with the knives and from a press plate or the like held on the cutting table. With the two Side knives become the head and foot side at the same time of the material to be cut. Before or after in a further step the cut with the front knife the front. The trimmed material is cut automatically moved out of the cutting area and for example by means of a conveyor belt removed from the three-cutting machine. at These three-knife cutting machines are thus cut in a single cutting station. Since the material to be cut is only once it has to be aligned, there are significant advantages compared to three-knife cutting machines with two stations. So that the front and side knives do not collide Front cut and side cut out of phase.

Eine Dreimesserschneidemaschine nach dem Oberbegriff des Anspruchs 1 ist beispielsweise in der DE 32 01 836 A offenbart. Diese weist eine Antriebsvorrichtung für die Messer auf, die jeweils ein sog. Führungsgetriebe und ein diesem vorgeschaltetes sog. Funktionsgetriebe aufweist. Das Funktionsgetriebe wird durch ein Zahnradgetriebe mit einem sich während eines Umlaufs einer Eintourenwelle ändernden Übersetzungsverhältnisses gebildet. Eine weitere Dreimesserschneidemaschine ist in der CH 537 260 A offenbart. Bei dieser erfolgt der Antrieb für die Messer mit einer angetriebenen, im Maschinenkörper gelagerten Eintourenwelle. An den Enden der Eintourenwelle ist je eine Kurbel angeordnet, an deren Kurbelzapfen je eine Pleuelstange angreift. Für den Antrieb des Frontmessers ist zudem eine Kreuzgelenkzugstange vorgesehen, die es ermöglichen soll, den bisher üblichen zweiseitigen Messerzug durch einen einseitigen Messerzug zu ersetzen. Auch diese Dreimesserschneidemaschinen sind in ihrem Aufbau und insbesondere im Aufbau des Antriebes vergleichsweise aufwendig.A three-knife cutting machine according to the preamble of claim 1 is for example disclosed in DE 32 01 836 A. This one Drive device for the knives, each of which is a so-called Guide gear and a so-called functional gear connected upstream having. The functional gear is through a Gear transmission with one during one revolution one A touring wave changing gear ratio formed. Another three-knife cutting machine is in CH 537 260 A reveals. This is where the knives are driven a driven single-speed shaft mounted in the machine body. A crank is arranged at the ends of the single-turn shaft, a connecting rod engages each of the crank pins. A universal joint pull rod is also used to drive the front knife provided that should make it possible to use the usual double-sided knife pull through a single-sided knife pull to replace. These three-knife cutting machines are also comparatively in their structure and in particular in the structure of the drive consuming.

Der Erfindung liegt die Aufgabe zugrunde, eine Dreimesserschneidemaschine der genannten Art zu schaffen, die einen einfacheren Aufbau mit weniger Teilen besitzt und die dennoch funktionssicher ist.
Erfindungsgemäss wird die Aufgabe duch die Merkmale des Anspruchs 1 gelöst. The invention has for its object to provide a three-knife cutting machine of the type mentioned, which has a simpler structure with fewer parts and which is still reliable.
According to the invention the object is achieved by the features of claim 1.

Der Antrieb der beiden Hebel mit einer einzigen Antriebskurve ermöglicht einen einfachen Aufbau mit wenigen Teilen sowie eine deformationsarme Bewegung.The two levers are driven by a single drive curve enables a simple construction with few parts as well as one low deformation movement.

Bei der erfindungsgemässen Dreimesserschneidemaschine ist die Antriebskurve endlos ausgebildet. Diese Kurve bewegt wenigstens zwei schwenkbare Hebel, mit denen das Frontmesser und wenigstens ein Seitenmesser angetrieben werden. Der Antrieb der Messer erfolgt somit über lediglich eine Kurve. Durch Gestaltung dieser Kurve kann die ungleichförmige Bewegung der Messer bestimmt werden. Der Antrieb mit der gemeinsamen Antriebskurve ergibt eine phasenverschobene Bewegung der Messerträger. Da die Antriebsvorrichtung mit wenigen und robusten Einzelteilen herstellbar ist, ergibt sich zudem eine sehr deformationsarme Bewegung der Messer bzw. der Messerträger.In the three-knife cutting machine according to the invention, the Drive curve endlessly formed. This curve at least moves two swiveling levers with which the front knife and at least a side knife to be driven. The drive of the Messer therefore takes place over just one curve. By design This curve can cause the uneven movement of the knives be determined. The drive with the common drive curve results in a phase-shifted movement of the knife carrier. There the drive device with few and robust individual parts is producible, there is also a very low deformation Movement of the knife or knife holder.

Die Antriebskurve wird beispielsweise über ein Ritzel angetrieben und bewegt gleichzeitig wenigstens zwei Hebel, mit denen das Frontmesser und wenigstens ein Seitenmesser angetrieben werden. Bei einem zweiseitigen Messerzug kann eine zweite Antriebskurve vorgesehen sein, die mit der ersten Antriebskurve über eine torsionssteife Welle verbunden ist.
Der Hebel für das Frontmesser ist vorzugsweise ein Gestänge, das an einer Messerkoppel angreift. Die beiden Seitenmesser sind vorzugsweise im Abstand zueinander auf einer Trägerwelle befestigt, die mit wenigstens einem der genannten Hebel zur Ausführung der Schneidbewegungen antriebsverbunden ist. Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.The drive curve is driven, for example, via a pinion and simultaneously moves at least two levers with which the front knife and at least one side knife are driven. In the case of a double-sided knife train, a second drive curve can be provided, which is connected to the first drive curve via a torsionally rigid shaft.
The lever for the front knife is preferably a linkage that engages a knife belt. The two side knives are preferably fixed at a distance from one another on a carrier shaft which is drive-connected to at least one of the levers mentioned for carrying out the cutting movements. Further advantageous features result from the dependent claims, the following description and the drawing.

Am anderen Ende des Hebels 19 ist ein Drehgelenk 14 angeordnet, welches den Hebel 19 mit einer Stange 10 verbindet, die an einem oberen Ende 10a drehbar mit der Trägerwelle 11 verbunden ist. Zwischen der Achse 20 und dem Gelenk 14 ist eine Kurvenrolle 21 am Hebel 19 angeordnet, welche in die Antriebskurve 23 eingreift. Die Antriebskurve 23 kann als geschlossene Kurve oder als offene Kurve ausgebildet sein. Vorzugsweise ist die Antriebskurve 23 eine geschlossene Kurve, mit der vergleichsweise grosse Schnittkräfte aufgenommen werden können. Grundsätzlich ist aber auch eine offene Kurve mit Feder oder Komplementärkurve denkbar. Die Stange 10 führt bei angetriebener Kurvenscheibe 22 Bewegungen gemäss dem Doppelpfeil 39 aus. Entsprechend werden die Streben 29 um eine gestellfeste Achse 40 verschwenkt.A second lever is simultaneously activated by the drive curve 23 19 moves, the one-armed and at one end around an axis 20 is pivotable on a bearing 35 fixed to the frame is supported. At the other end of the lever 19 is a swivel 14 arranged, which the lever 19 with a rod 10th connects that at an upper end 10a rotatably with the carrier shaft 11 is connected. Between the axis 20 and the joint 14, a cam roller 21 is arranged on the lever 19, which engages in the drive curve 23. The drive curve 23 can be designed as a closed curve or as an open curve. The drive curve 23 is preferably a closed curve, with which comparatively large cutting forces are absorbed can. Basically, there is also an open curve Spring or complementary curve conceivable. The rod 10 leads driven cam 22 movements according to the double arrow 39 out. Accordingly, the struts 29 are fixed to the frame Axis 40 swiveled.

Wesentlich ist, dass das Gestänge 9 als auch die Stange 10 von der gleichen Antriebskurve 23 angetrieben sind. Die Antriebskurve 23 ist umlaufend und so gestaltet, dass das Gestänge 9 als auch die Stange 10 phasenverschoben bewegt werden. Die Schwenkbewegungen der Hebel 16 und 19 erfolgt jeweils dann, wenn die Kurvenrolle 18 bzw. 21 in einen zurückversetzten Bereich 23a einlaufen. Wird die Kurvenscheibe 22 in Richtung des Pfeiles 25 gedreht, so wird in Figur 1 zuerst der Hebel 16 und anschliessend der Hebel 19 verschwenkt. Entsprechend wird zuerst mit dem Frontmesser 4 und anschliessend mit den Seitenmessern 5 und 6 geschnitten.It is essential that the linkage 9 and the rod 10 of the same drive curve 23 are driven. The drive curve 23 is circumferential and designed so that the linkage 9 and the rod 10 are moved out of phase. The Swiveling movements of the levers 16 and 19 take place in each case when the cam roller 18 or 21 in a recessed area 23a. If the cam 22 in the direction of Arrow 25 rotated, the lever 16 and then the lever 19 is pivoted. Accordingly, first with the front knife 4 and then with the side knives 5 and 6 cut.

Sind der Frontschnitt und die Seitenschnitte durchgeführt, muss das Schnittgut 30 von der Maschine 1 weggeführt und gleichzeitig muss ein weiteres zu beschneidendes Schnittgut dem Schneidetisch zugeführt und auf diesem fixiert werden. In der zur Verfügung stehenden Zykluszeit muss das Schneidgut 30 somit ausgerichtet, geschnitten und wegtransportiert werden. Beim Wegtransport des Schnittgutes 30 müssen das Frontmesser 4 und die beiden Seitenmesser 5 und 6 in einer Position sein, in welcher der genannte Transport möglich ist. Durch entsprechende Gestaltung der Antriebskurve 23 kann dies erreicht werden. Insbesondere können die Messer 4, 5 und 6 durch eine entsprechende Gestaltung der Antriebskurve 23 so beschleunigt bzw. verzögert werden, dass die für den Transport verbleibende Zykluszeit optimal ist.Once the front cut and the side cuts have been made, the clippings 30 must be led away from the machine 1 and at the same time, another clippings to be trimmed fed to the cutting table and fixed on it. In of the available cycle time, the material to be cut 30 thus aligned, cut and transported away. When the cut material 30 is transported away, the front knife 4 and the two side knives 5 and 6 are in one position in which transport is possible. By appropriate Design of the drive curve 23, this can be achieved. In particular, the knives 4, 5 and 6 can be replaced by a corresponding one Design of the drive curve 23 accelerated or that the cycle time remaining for the transport is delayed is optimal.
