Abstract

The trimmer has a upper and lower blade holders with top and bottom cutting blades located on the blade holders being across from each other. Tensioners lock the lower blade holders on a guide rail. The tensioners are actuated from the side of the trimmer. A common actuator acts on the tensioners. The tensioners form a tie rod, with a lower blade holder pressed against the guide rail configuration.

Description

Die Erfindung betrifft einen Trimmer zum Beschnitt von Broschuren mit Untermesserhaltern und Obermesserhaltern für Kopfschnitt-Messer und diesen gegenüber stehende Fußschnitt-Messer, einer Führungsschienenanordnung und mit Spannern, mittels welcher die Untermesserhalter an der Führungsschienenanordnung arretierbar sind.The invention relates to a trimmer for trimming brochures with lower blade holders and upper blade holders for overhead cutters and these opposed Fußschnitt-knife, a guide rail assembly and with tensioners, by means of which the lower blade holder can be locked to the guide rail assembly.

Derartige Trimmer wurden von der Anmelderin als jeweiliger Bestandteil von Sammelheftern mit den Typenbezeichnungen ST100 und ST300 vertrieben. Die genannte Führungsschienenanordnung und die Spanner dienen der Anpassung von Kopf- und Fußschnittmessern an die zu erstellende Rückenlänge der Broschuren. Die Dauer dieser Anpassung geht in die Rüstzeit ein, innerhalb welcher Trimmer umfassende Sammelhefter von einem Broschurenformat auf ein anderes umgestellt werden.Such trimmers have been marketed by the Applicant as a respective component of saddle stitchers of the type designations ST100 and ST300. Said guide rail arrangement and the tensioner serve to adapt head and foot cutters to the back length of the brochures to be created. The duration of this adjustment is included in the setup time, within which trimmers comprehensive saddle stitchers are changed from one brochure format to another.

Aus der DE 41 39 137 , aus der die Merkmale des Oberbegriffs des Anspruchs 1 bekannt sind, ist eine Vorrichtung zum Quereinstellen der Messer eines Formatschneiders bekannt, bei dem die Schneidmesserträger mittels Schrauben an Führungen arretiert sind. Nach Lösen der Schrauben können dann aufgrund einer Verspannung von Ober- und Untermesser über einen Stützkörper die Ober- und Untermesser gemeinsam verstellt werden. Nachteilig an der Anordnung ist, dass die Schneidmesserträger einzeln gelöst werden müssen, was zeitaufwendig ist, weil der Bediener nicht von einer Seite die Schrauben lösen kann.From the DE 41 39 137 , from which the features of the preamble of claim 1 are known, a device for adjusting the diameter of the knife of a format cutter is known, in which the cutting blade carrier are locked by means of screws on guides. After loosening the screws, the upper and lower blades can then be adjusted together due to a tension of the upper and lower blade on a support body. A disadvantage of the arrangement is that the cutting blade carrier must be solved individually, which is time consuming because the operator can not solve the screws from one side.

Der Erfindung liegt die Aufgabe zugrunde, die zur Umrüstung einer einen Trimmer umfassenden Drucknachbearbeitungsmaschine wie z. B. eines Sammelhefters von einem Broschurenformat auf ein anderes erforderliche Zeit möglichst kurz zu halten.The invention is based on the object for the conversion of a trimmer comprehensive post-processing machine such. B. a saddle stitcher from a brochure format to another required time as short as possible.

Zur Lösung dieser Aufgabe ist vorgesehen, dass die Spanner des eingangs genannten Trimmers von ein und derselben Seite desselben betätigbar sind, wobei ein jeweiliger Spanner eine verlagerbare Spannkurve, einen mit der Spannkurve zusammenwirkenden Kurvenfolger und ein mit dem Kurvefolger verbundenes Spannglied umfasst. Dies wirkt sich insofern günstig auf die zur Umrüstung erforderliche Zeit aus, als ein Weg eines Einrichters entfällt, der bei dem eingangs genannten zu einem Sammelhefter gehörigen Trimmer insofern erforderlich ist als dort ein Spanner für einen ein Untermesser für den Kopfschnitt tragenden Messerhalter und ein Spanner für einen ein Untermesser für den Fußschnitt tragender Messerhalter nur von einander gegenüberliegenden Seiten des Trimmers zugänglich sind. Falls hierfür im Falle einer verkettenden Anlage keine Brücke vorgesehen ist, können nämlich lange Wege erforderlich sein; um von einer auf die gegenüberliegende Seite des Trimmers zu gelangen. Selbst ein Gang über eine gegebenenfalls vorgesehene Brücke erfordert seine Zeit. Diese Zeit wird jedoch mit einer Ausstattung eines eingangs genannten Trimmers gemäß vorliegender Erfindung eingespart.To achieve this object, it is provided that the tensioner of the above-mentioned trimmer from the same side thereof are actuated, wherein a respective tensioner comprises a displaceable tension curve, a cooperating with the tension curve follower and connected to the curve follower tendon. This has a favorable effect on the time required for retrofitting, as a way of a setter is eliminated, which in the above-mentioned belonging to a saddle stitcher Trimmer is required insofar as there are a tensioner for a lower blade for the headcut carrying knife holder and a tensioner for a bottom knife carrying the footcut knife holder only accessible from opposite sides of the trimmer. If, in the case of a linking system, no bridge is provided for this, long paths may be required; to get from one to the opposite side of the trimmer. Even a walk over an optional bridge requires time. However, this time is saved with the equipment of an aforementioned trimmer according to the present invention.

Die Merkmale des erfindungsgenstandes und von dessen Ausgestaltungen sind den beigefügten Zeichnungen und den darauf Bezug nehmenden nachfolgenden Erläuterungen entnehmbar.The features of the subject invention and of its embodiments are the appended drawings and the subsequent explanations taken to be taken.

Die Untermesserhalter 1.1 und 1.2 sind auf eine Führungsschienenanordnung 5 aufgesetzt und bilden Führungen 6.1 und 6.2 für die Obermesserhalter 2.1 und 2.2 aus. Zur Anpassung der Kopfschnittmesser 3.1 und 3.2 und der Fußschnittmesser 4.1 und 4.2 an die Rückenlänge der jeweils zu entstellenden Broschur sind die Untermesserhalter 1.1 und 1.2 entlang der Führungsschienenanordnung 5 verschiebbar und zwar in einem gelöstem Zustand von hier nicht gezeigten Spannern, welche in einem gespannten Zustand die Untermesserhalter 1.1 und 1.2 bezüglich der Führungsschienenanordnung 5 arretieren, in dem sie zwischen dem jeweiligen Untermesserhalter 1.1 und 1.2 einerseits und einer jeweiligen Klemmleiste 7.1 und 7.2 - die der Führungsschienenanordnung 5 auf einer den Untermesserhaltern 1.1 und 1.2 abgewanden Seite zugeordnet sind - andererseits eine Zugkraft hervorrufen, die zu einem Reibschluss zwischen der Führungsschienenanordnung 5 und dem jeweiligen Untermesserhalter 1.1 und 1.2 führt.As in Fig. 1 indicated, includes a trimmer lower blade holder 1.1 and 1.2 and upper blade holder 2.1 and 2.2 for chisel 3.1 and 3.2 and Fußschnittmesser 4.1 and 4.2. The lower blade holder 1.1 and 1.2 are placed on a guide rail assembly 5 and form guides 6.1 and 6.2 for the outer blade holder 2.1 and 2.2. To adapt the chisel cutters 3.1 and 3.2 and the foot cutters 4.1 and 4.2 to the back length of each paperback to be distorted the lower knife holder 1.1 and 1.2 along the guide rail assembly 5 are displaceable and in a dissolved state of tensioners not shown here, which in a tensioned state Lock lower blade holder 1.1 and 1.2 with respect to the guide rail assembly 5, in which they cause a tensile force between the respective lower blade holder 1.1 and 1.2 on the one hand and a respective terminal block 7.1 and 7.2 - which are associated with the guide rail assembly 5 on a side facing the lower blade holders 1.1 and 1.2 - on the other hand which leads to a frictional engagement between the guide rail assembly 5 and the respective lower blade holder 1.1 and 1.2.

In Fig. 2 ist - herausgelöst aus einem Trimmer - die beim vorliegenden Ausführungsbeispiel aus zwei Führungsschienen 5.1 und 5.2 gebildete Führungsschienenanordnung 5, ein darauf aufgesetzter, einer Bedienseite des Trimmers zugewandter Untermesserhalter 1.1, ein zu dessen Arretierung auf der Führungsschienenanordnung 5 ausgebildeter Spanner 7 und ein mit diesem zusammen wirkender Betätiger 8 wiedergegeben. Für den aus Fig. 1 erkennbaren zweiten Untermesserhalter 1.2 ist eine im Wesentlichen gleiche Konstellation wie für den in Fig. 2 ersichtlichen Untermesserhalter 1.1 vorgesehen. Abweichend hiervon ist jedoch im Falle eines separaten Betätigers für den dem zweiten Untermesserhalter 1.2 zugeordneten Spanner lediglich die Länge dieses Betätigers, da sich dieser hierbei von seinem Wirkort jenseits des in Fig. 2 erkennbaren Untermesserhalters 1.1 über diesen hinaus bis zu einem Betätigungsort erstreckt, der räumlich in der Nachbarschaft jenes Betätigungsortes liegt, an dem der Spanner 7 für den der Bedienseite zugewandten Untermesserhalter 1.1 (siehe Fig. 2) betätigt wird.In Fig. 2 is - dissolved out of a trimmer - in the present embodiment of two guide rails 5.1 and 5.2 formed guide rail assembly 5, a patch attached to an operating side of the trimmer lower knife holder 1.1, a trained on the guide rail assembly 5 tensioner 7 and a cooperating with this Actuator 8 reproduced. For the out Fig. 1 identifiable second lower knife holder 1.2 is a substantially same constellation as for in Fig. 2 apparent underside knife holder 1.1 provided. Deviating from this, however, in the case of a separate actuator for the second lower knife holder 1.2 associated tensioner only the length of this actuator, since this case of his site of action beyond the in Fig. 2 recognizable lower blade holder 1.1 beyond this extends to an actuation location, which is spatially in the vicinity of that actuation location at which the tensioner 7 for the operating side facing lower blade holder 1.1 (see Fig. 2 ) is pressed.

Insoweit sind die Spanner 7 beider Untermesserhalter 1.1 und 1.2, also jener für den Kopfschnitt und jener für den Fußschnitt, von ein und derselben Seite des Trimmers aus betätigbar.In that regard, the tensioner 7 both bottom knife holder 1.1 and 1.2, ie those for the top section and that for the foot section, from one and the same side of the trimmer from actuated.
