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, its blade shafts in a working position parallel to each other between two spaced side walls of the Folding machine are stored.

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. To fold folded paper sheets perpendicular to a fold line, d. H. in sheet travel direction Cutting, cutting, perforating, crimping, etc. are the Crimping rollers of a folding unit Pre-set or adjusted knife shaft pairs. there These are usually knife shaft pairs, where one Knife shaft with upper knife tools and the other knife shaft with Bottom knife tools mounted on a mounted on the knife shaft Tool holder are arranged. The knife shafts are ever equipped with appropriate tools upon request of the order. A corresponding folding machine is for example in DE 30 25 239 C2 disclosed. The knife shafts are usually in the known folding machines stored on the side walls of the folding machine. For this Reason they can only be taken at a standstill of the folding machine become. For this it is usually necessary to first pull out the folding pockets. Subsequently, the knife shafts after loosening their attachment lifted out over the side walls of the machine. There the knife shafts usually have a very high weight, this is Work very hard. Finally, the knife shafts can only be accurate adjusted when installed in the folding machine. These are Aid attached in the immediate vicinity of the knife shafts. These are e.g.

Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln eine Falzmaschine zu schaffen, bei der ein schneller Wechsel der Messerwellen auf einfache Weise möglich ist.The invention is based on the object with structurally simple means to create a folding machine, in which a quick change of the knife shafts is possible in a simple way.

Diese Aufgabe wird durch eine Falzmaschine mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a folding machine with the features of the claim 1 solved.

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 Demontage der Falztaschen eines vorgeschalteten Falzwerks möglich. Darüber hinaus ist es möglich, ein Messerwellenpaar während des Laufs der Falzmaschine voreinzustellen, wodurch die Rüstzeit wesentlich verringert werden kann.Because the knife shafts are stored in the cassette, passing through the sidewall from the insertion position in the extended position is displaceable, is a Changing the blade shafts without dismantling the folding pockets of an upstream Folding mechanism possible. In addition, it is possible to use a pair of knife shafts preset during the course of the folding machine, causing the Setup time can be significantly reduced.

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 arranged in a drawer passing through the Side wall can be inserted and pulled out. When the drawer is pulled out is, the cassette can be removed and a new cassette on the drawer are hung up. After inserting the drawer is the Change of the knife shaft pair finished.

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 particular embodiment, the cassette has a drive-side End wall and a user-side end wall, which are at a distance from each other arranged and connected by a crossbar. The Knife shafts are mounted on the forehead 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 außerhalb der Falzmaschine erfolgen.Preferably, the storage facilities are at least one blade shaft to Adjustment of the gap between the knife shafts adjustable. This adjustment is part of the knife shaft cassette. The adjustment can be done outside outside the folding machine.

Für eine schnelle Verbindung mit dem falzmaschinenseitigen Antrieb können die antriebsseitigen Lagereinrichtungen in der antriebsseitigen Stirnwand drehbar gelagert sein und durch diese hindurchgehen.For a fast connection with the folding machine drive the drive-side storage facilities in the drive-side end wall be rotatable and pass through it.

Zur Zentrierung der Kassette ist es vorteilhaft, wenn an der beiden Stirnwänden jeweils ein Passstift angebracht ist, der in der Einschubstellung in eine Zentrieröffnung in der jeweiligen Seitenwand der Falzmaschine eingreift.For centering the cassette, it is advantageous if at the two end walls in each case a dowel pin is attached, which in the insertion position in a Centering engages in the respective side wall of the folding machine.

Eine genaue Einstellung von Messerhaltern auf den Messerwellen kann dadurch erreicht werden, dass auf der Messerwelle eine Maßeinteilung vorgesehen ist, die vorzugsweise eingraviert ist.An exact adjustment of knife holders on the knife shafts can thereby be achieved that provided a scale on the knife shaft is, which is preferably engraved.

Da die Einstellung der Messerhalter auf den Messerwellen außerhalb der Maschine erfolgen kann, kann der Bediener beim Werkzeugwechsel direkt vor der Messerwellenkassette stehen, so dass kein Paralaxenfehler auftritt.Since the adjustment of the knife holder on the cutter shafts outside the Machine can be done, the operator when changing tools directly stand in front of the knife shaft cassette so that no parallax error occurs.

Die Werkzeughalter 26 sind lösbar auf dem Wellenkörper 23 der Messerwellen 22, 24 angebracht. Eine genaue Positionierung der Werkzeughalter 26 auf den Messerwellen 22, 24 wird durch eine Maßeinteilung ermöglicht, wie sie in den Fig. 6 und 7 gezeigt ist. Als Maßeinteilung 52 ist in Längsrichtung der Messerwellen 22, 24 ein Nonius in die Oberfläche des Wellenkörpers 23 der Messerwellen 22, 24 eingraviert. Aufgrund der genauen Maßeinteilung 52 direkt auf der Messerwelle 22, 24 ist es möglich, einen Werkzeughalter 26 präzise auf der Messerwelle 22, 24 zu befestigen. Die Genauigkeit der Befestigung wird zusätzlich dadurch erhöht, dass es einem Bediener möglich ist, die Werkzeughalter 26 außerhalb der Falzmaschine 10 an den Messerwellen 22, 24 zu befestigen. Hierdurch wird ein Paralaxenfehler vermieden.The tool holders 26 are detachably mounted on the shaft body 23 of the cutter shafts 22, 24 attached. Accurate positioning of the tool holder 26 on the knife shafts 22, 24 is enabled by a scale, such as it is shown in Figs. 6 and 7. As scale 52 is in the longitudinal direction the knife shafts 22, 24 a vernier in the surface of the shaft body 23rd the knife shafts 22, 24 engraved. Due to the exact scale 52 directly on the blade shaft 22, 24, it is possible a tool holder 26th to be mounted precisely on the knife shaft 22, 24. The accuracy of attachment is additionally increased by making it possible for an operator is the tool holder 26 outside the folding machine 10 on the blade shafts 22, 24 fasten. This avoids a parallax error.
