An bekannten Dreimesserschneidemaschinen sind meist lineare Gleitführungselemente zur Führung der Seitenschneidein richtung eingesetzt.Known three-knife cutting machines are mostly linear Sliding guide elements for guiding the side cutters direction used.
Dabei kommen zur Realisierung des Schrägschwingschnittes der Seitenmesser sowohl für die Schrägführung der Seitenmesserträgerwelle als auch zur Führung eines Lenkers, zur Realisierung der Schwingbewegung der Seitenmesser lineare Gleitführungselemente wie z. B. Gleitsteine und Gleitstein führungen zum Einsatz.Thereby come to realize the oblique swing cut the side knife for both the diagonal guidance of the Side knife carrier shaft as well as for guiding a handlebar, linear to realize the swinging movement of the side knives Slideway elements such. B. sliding blocks and sliding block guides to use.
Das funktionsbedingt erforderliche Spiel zwischen den Führungselementen und deren Gleitverschleiß können beispiels weise zu einer ungewollten Verlagerung der Seitenschneid einrichtung während des Schnittprozesses führen, was einen qualitätsgeminderten Schnitt zur Folge haben würde.The functionally required game between the Guide elements and their sliding wear can, for example indicate an unwanted shift of the side cutting set up during the cutting process, what a quality cut would result.
Um diesen Nachteil zu beseitigen, wird in der DE 42 06 341 der Einsatz von Linearwälzführungseinheiten vorgeschlagen. Die Linearwälzeinheiten bestehen aus, mit unterschiedlichen Koordinaten und unterschiedlichen Winkeln am Maschinenge stell angebrachten Linearführungen und diesen zugeordneten Wälzeinheiten, die über Hebel drehbar mit der Seitenmesser trägerwelle verbunden sind.To eliminate this disadvantage, DE 42 06 341 the use of linear roller guide units proposed. The linear roller units consist of different ones Coordinates and different angles on the machine narrow attached linear guides and assigned to them Rolling units that can be rotated via levers with the side knife carrier shaft are connected.
Der Zwangsverlauf ergibt sich dabei durch die Verbindung der beiden ebenen Koppelgetriebe mittels der Seiten messerträgerwelle.The constraint results from the connection of the two flat coupling gears by means of the sides knife carrier shaft.
Nachteilig ist bei dieser Lösung der durch die Dreh gelenke Wälzeinheit - Hebel an der Seitenmesserträger welle hervorgerufene hohe konstruktive Aufwand.The disadvantage of this solution is that due to the rotation articulated roller unit - lever on the side knife carrier wave-induced high design effort.
Aufgabe der Erfindung ist es, eine Seitenschneid einrichtung für Dreimesserschneidemaschinen zum Be schneiden von Buchblocks, Broschüren o. dgl. mit einer die Seitenmesser aufnehmenden, durch einen Antrieb in Führungs einheiten im Schrägschwingschnitt angetriebenen Seiten- Messerträgerwelle, so zu gestalten, daß der konstruktive Aufwand verringert und durch den Wegfall von Getriebegliedern gegenüber dem Stand der Technik neben der Verbesserung der Schnittqualität auch eine Verringerung des Herstellungs- und Wartungsaufwandes erzielt wird. The object of the invention is a side cutting device for three-knife cutting machines for loading cutting of book blocks, brochures or the like with one the side knives by a drive in the guide units in the oblique swing cut driven side Knife carrier shaft, so that the constructive Reduced effort and by eliminating gear links compared to the state of the art in addition to improving the Cut quality also a reduction in manufacturing and Maintenance effort is achieved.
Erfindungsgemäß wird die Aufgabe an einer Seiten schneideinrichtung für Dreimesserschneidemaschinen zum Beschneiden von Buchblocks, Broschüren o. dgl. mit einer Seitenmesser aufnehmenden, durch einen Antrieb in Führungseinheiten im Schrägschwingschnitt angetriebene Seitenmesserträgerwelle dadurch gelöst, daß die Führungsein aus, mit dem Messergestell fest verbundenen gekrümmten Führungsschienen, denen verfahrbare, mit der Seitenmesser trägerwelle drehfest verbundene Führungsschlitten zugeordnet sind, bestehen.According to the task on one side cutting device for three-knife cutting machines for trimming book blocks, brochures or the like with a side knife receiving, by a drive driven in guide units in the oblique swing cut Side knife carrier shaft solved in that the guide from, curved with the knife frame firmly connected Guide rails, which are movable, with the side knife Carrier shaft assigned to non-rotatably connected guide carriages are exist.
Die Führungsschienen können auch mit der Seitenmesserträger welle und die Führungsschlitten mit dem Maschinengestell ver bunden sein.The guide rails can also be used with the side knife holder shaft and the guide carriage with the machine frame be bound.
Dabei können die Führungseinheiten als Gleitführungskombi nationen oder als Wälzführungskombinationen ausgebildet sein.The guide units can be used as a sliding guide combination nations or be designed as roller guide combinations.
Vorteilhafter wäre, die Führungseinheiten als direkt gleich laufgesteuerte Antriebseinheiten auszubilden, wobei die Krümmung der Führungsschiene einen unstetigen Verlauf haben kann.It would be more advantageous if the management units were directly the same train run-controlled drive units, the Curvature of the guide rail have a discontinuous course can.
