Description

Die Erfindung betrifft eine Falzmaschine mit wenigstens einem Messerwellenpaar, dessen Messerwellen in einer Arbeitsstellung parallel zueinander zwischen zwei im Abstand zueinander angeordneten Seitenwänden der Falzmaschine gelagert sind.The invention relates to a folding machine with at least one pair of knife shafts, whose knife shafts in a working position parallel to each other between two in Side walls of the folding machine which are arranged at a distance from one another are mounted.

Um gefalzte Papierbogen senkrecht zu einer Falzlinie, d. h. in Bogenlaufrichtung schneiden, ausschneiden, perforieren, crimpen etc. zu können, sind den Falzwalzen eines Falzwerks Messerwellenpaare vor- bzw. nachgestellt. Dabei handelt es sich in der Regel um Messerwellenpaare, bei denen eine Messerwelle mit Obermesserwerkzeugen und die andere Messerwelle mit Untermesserwerkzeugen bestückt ist, die auf einem auf der Messerwelle angebrachten Werkzeughalter angeordnet sind. Die Messerwellen werden je nach Anforderung des Auftrags mit entsprechenden Werkzeugen bestückt. Eine entsprechende Falzmaschine ist beispielsweise in der DE 30 25 239 C2 offenbart. Die Messerwellen werden bei den bekannten Falzmaschinen üblicherweise an den Seitenwänden der Falzmaschine gelagert. Aus diesem Grund können sie nur bei einem Stillstand der Falzmaschine entnommen werden. Hierzu ist es in der Regel erforderlich, zunächst die Falztaschen herauszuziehen. Anschließend müssen die Messerwellen nach Lösen ihrer Befestigung über die Seitenwände der Maschine herausgehoben werden. Da die Messerwellen in der Regel ein sehr hohes Gewicht aufweisen, ist diese Arbeit sehr mühsam. Schließlich können die Messerwellen nur dann genau eingestellt werden, wenn sie in die Falzmaschine eingebaut sind. Hierzu sind Hilfsmittel in unmittelbarer Nähe der Messerwellen angebracht. Dies sind z.B. Lineale mit aufgedrucktem Maßband, an denen die Lage des Werkzeugs abgelesen werden kann.To make folded sheets of paper perpendicular to a fold line, i.e. H. in the direction of sheet travel Being able to cut, cut, perforate, crimp etc. are the folding rollers a pair of knife shafts preceded or readjusted. It is in usually around pairs of knife shafts where a knife shaft with upper knife tools and the other knife shaft is equipped with bottom knife tools, which are arranged on a tool holder attached to the knife shaft. Depending on the requirement of the order, the knife shafts are equipped with appropriate Tools. A corresponding folding machine is for example in the DE 30 25 239 C2 discloses. The knife shafts are used in the known folding machines usually stored on the side walls of the folding machine. For this For this reason, they can only be removed when the folding machine is at a standstill. To do this, it is usually necessary to first pull out the folding pockets. The knife shafts must then be loosened from the side walls be lifted out of the machine. Because the knife shafts usually have a very high weight, this work is very tedious. Finally, you can the knife shafts can only be set precisely when they are in the folding machine are installed. For this purpose, tools are attached in the immediate vicinity of the knife shafts. These are e.g. Rulers with printed measuring tape, on which the position of the Tool can be read.

Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln eine Falzmaschine sowie eine Messerwelle zu schaffen, die einen schnellen Wechsel der Messerwellen auf einfache Weise ermöglichen. The invention has for its object a structurally simple means Folding machine as well as a knife shaft to create a quick change of Enable knife shafts in a simple way.

Da die Messerwellen in der Kassette gelagert sind, die durch die Seitenwand aus der Einschubstellung in die Auszugsstellung verschiebbar ist, ist ein Wechsel der Messerwellen ohne Herausziehen der Falztaschen des vorgeschalteten Falzwerks möglich. Darüber hinaus ist es möglich, ein Messerwellenpaar während des Laufs der Falzmaschine voreinzustellen, wodurch die Rüstzeit wesentlich verringert werden kann.Since the knife shafts are stored in the cassette, which is through the side wall from the Insert position in the pull-out position is a change of the knife shafts possible without pulling out the folding pockets of the upstream folder. In addition, it is possible to use a pair of knife shafts during the run Presetting the folding machine, which significantly reduces makeready times can.

Vorzugsweise ist die Kassette in einer Schublade angeordnet, die durch die Seitenwand einschiebbar und herausziehbar ist. Wenn die Schublade herausgezogen ist, kann die Kassette entnommen und eine neue Kassette auf die Schublade aufgelegt werden. Nach Einschieben der Schublade ist der Wechsel des Messerwellenpaares beendet.Preferably, the cassette is placed in a drawer through the side wall can be pushed in and pulled out. When the drawer is pulled out the cassette can be removed and a new cassette placed on the drawer become. After inserting the drawer, the knife shaft pair has to be changed completed.

In einer besonderen Ausführungsform weist die Kassette eine antriebsseitige Stirnwand und eine bedienerseitige Stirnwand auf, die im Abstand zueinander angeordnet und durch eine Traverse miteinander verbunden sind. Die Messerwellen sind an der Stirn durch Lagereinrichtungen gelagert.In a special embodiment, the cassette has an end wall on the drive side and an operator-side end wall which is arranged at a distance from one another and are connected to each other by a traverse. The knife shafts are on the Forehead stored by storage facilities.

Vorzugsweise sind die Lagereinrichtungen wenigstens einer Messerwelle zur Einstellung des Spaltes zwischen den Messerwellen verstellbar. Diese Verstelleinrichtung ist Bestandteil der Messerwellenkassette. Die Verstellung kann außerhalb der Falzmaschine erfolgen.The bearing devices are preferably at least one knife shaft for adjustment the gap between the knife shafts adjustable. This adjustment device is part of the knife shaft cassette. The adjustment can be made outside the folding machine respectively.
