Description

Die Erfindung betrifft eine Schneidvorrichtung für Druckbogenstapel nach dem Oberbegriff des Anspruchs 1.The invention relates to a cutting device for printing sheet stack according to the preamble of claim 1.

Derartige Schneidvorrichtungen sind in Maschinen zur Herstellung von Broschüren, Heften, Zeitschriften oder dergleichen in Gebrauch, bei der mittels einer Transportvorrichtung von sogenannten Anlegern die einzelnen Bogen zu fertigen Druckbogenstapeln gesammelt und einer Heftstation zugeführt werden. Nach dem Heften werden die gehefteten Druckbogenstapel in einer Schneidvorrichtung an den drei offenen Seiten beschnitten, so dass sich ein präzises, gleichbleibendes Format für alle Druckbogenstapel mit glatten Rändern ergibt. Eine derartige Schneidvorrichtung wird auch als Trimmer bezeichnet.Such cutting devices are in machines for the production of leaflets, booklets, magazines or the like in use, in which by means of a transport device by so-called investors, the individual sheets are collected to produce printed sheet stacks and fed to a stitching station. After stapling, the stapled sets of printed sheets are trimmed in a cutter on the three open sides, resulting in a precise, consistent format for all printed sheets with smooth edges. Such a cutting device is also referred to as a trimmer.

Handelsübliche Schneidvorrichtungen sind mit Seitenschiebern zur Positionierung der zu schneidenden Druckbogenstapel gegenüber einem Schneidmesser versehen, wobei eine Verstelleinrichtung für eine Positionsvorgabe der Seitenschieber vorgesehen ist, um die Schneidvorrichtung an unterschiedliche Druckbogenstapelformate anzupassen. Die Seitenschieber dienen zur Ausrichtung des Produkts für die richtige Kopfbeschnitt- oder Fußbeschnittposition in Verbindung mit einem dazu rechtwinkligen Frontbeschnitt. Die Ausrichtung der Broschüre erfolgt zunächst auf der Frontbeschnittposition, wobei die Seitenschieber kurz vor dem Kopfbeschnitt betätigt werden. Üblicherweise sind die Seitenschieber auf den die Messer tragenden Messerbalken befestigt, die zur Verstellung des Broschürenformats auf dem Gestell verfahrbar sind. Über die Positionierung des Seitenschiebers wird die Broschüre in der Lage zu den Messern für Kopf- und Fußbeschnitt ausgerichtet und somit der Kopf- und Fußbeschnitt eingestellt.Commercially available cutting devices are provided with side sliders for positioning the sheet stack to be cut with respect to a cutting blade, wherein an adjusting device for a position specification of the side shift is provided to adapt the cutting device to different sheet stacking formats. The sideshifters are used to align the product with the correct head trim or foot trim position in conjunction with a right-angled front trim. The orientation of the booklet is initially on the front trim position, with the side shifters just before the Head trim be operated. Usually, the side sliders are mounted on the cutter blades carrying the knife, which are movable on the frame for adjusting the brochure format. By positioning the sideshifter, the booklet is aligned with the knives for the head and foot trimming and thus the head and foot trim can be adjusted.

Die komplette Schneidvorrichtung wird üblicherweise mit einer Abdeckung oder Verkleidung versehen, so dass der Innenraum der Schneidvorrichtung vor einem Zugriff von außen geschützt ist und die damit verbundenen Gefahren durch die Schneidmesser für die Bedienpersonen vermieden werden.The entire cutting device is usually provided with a cover or panel, so that the interior of the cutting device is protected from external access and the associated risks are avoided by the cutting blade for the operator.

Bei am Markt vorhandenen Schneidvorrichtungen wird der Seitenschieber mit einem Verstellwagen im Innern der Schneidvorrichtung im Bereich des Seitenschiebers verstellt und verklemmt. Daher ist eine Verstellung bzw. Korrektur der Einstellung nur mit geöffneter Verkleidung bei stehender Maschine möglich.When existing on the market cutting devices of the side shift is adjusted and jammed with a Verstellwagen inside the cutter in the area of the side slide. Therefore, an adjustment or correction of the adjustment is possible only with the panel open when the machine is stationary.

Ausgehend von einer derartigen Schneidvorrichtung nach dem Stand der Technik hat die vorliegende Erfindung die Aufgabe, eine Schneidvorrichtung vorzuschlagen, bei der eine Verstellung wenigstens eines Seitenschiebers bei geschlossener Verkleidung und gegebenenfalls auch während des Betriebs möglich ist.Starting from such a cutting device according to the prior art, the present invention has the object to propose a cutting device in which an adjustment of at least one side slider is possible with the lining closed and possibly also during operation.

Diese Aufgabe wird bei einer Schneidvorrichtung gemäß dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst.This object is achieved in a cutting device according to the preamble of claim 1 by its characterizing features.

Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.The measures mentioned in the dependent claims advantageous embodiments and developments of the invention are possible.

Dementsprechend wird bei einer erfindungsgemäßen Schneidvorrichtung ein von außerhalb der Verkleidung zugängliches Betätigungsorgan für die Verstelleinrichtung vorgesehen. Dieses Bestätigungsorgan ist mit der Verstelleinrichtung über eine entsprechende Durchführung in den Innenraum der Verkleidung verbunden, so dass eine Verstellung des Seitenschiebers von außerhalb durch das Bedienpersonal möglich ist.Accordingly, in an inventive cutting device an accessible from outside the panel actuator for the adjustment is provided. This confirmation member is connected to the adjustment via a corresponding implementation in the interior of the panel, so that an adjustment of the side slider from the outside by the operating personnel is possible.

In einer besonderen Ausführungsform der Erfindung umfasst die Verstelleinrichtung einen in einer Führung gelagerten Verstellwagen. An diesem Verstellwagen kann der Seitenschieber befestigt, beispielsweise verschraubt werden. Der Verstellwagen ist dabei in einer Linearführung geführt und über ein Stellglied, das von außerhalb der Verkleidung zugänglich ist, in seiner Position verstellbar.In a particular embodiment of the invention, the adjusting device comprises a positioning carriage mounted in a guide. At this adjustment the side slide can be attached, for example, be screwed. The adjustment is guided in a linear guide and adjustable via an actuator that is accessible from outside the panel in position.

In einer vorteilhaften Ausführungsform der Erfindung wird ein Antrieb für die Verstellung wenigstens eines Seitenschiebers vorgesehen. Ein solcher Antrieb kann beispielsweise mit Hilfe eines Motors, insbesondere eines Elektromotors, oder aber auch über einen Arbeitszylinder, beispielsweise ein Pneumatikzylinder, gebildet werden. Die Ansteuerung dieses Antriebs wird erfindungsgemäß von außerhalb der Verkleidung zugänglich gestaltet, d.h. es befindet sich ein entsprechendes Schaltorgan, beispielsweise ein elektrischer Schalter oder ein Schaltventil, in einem von außerhalb der Verkleidung zugänglichen Bereich.In an advantageous embodiment of the invention, a drive for the adjustment of at least one side slide is provided. Such a drive can be formed for example by means of a motor, in particular an electric motor, or else via a working cylinder, for example a pneumatic cylinder. The drive of this drive is designed according to the invention accessible from outside the panel, i. There is a corresponding switching device, such as an electrical switch or a switching valve, in an accessible from outside the panel area.

In einer einfachen Ausführungsvariante wird ein manuell antreibbares Getriebeelement vorgesehen, das von außerhalb der Verkleidung zugänglich ist. In Frage kommt hierzu beispielsweise eine Spindelanordnung, die sich seitlich in den Bereich der Verkleidung oder durch diese hindurch erstreckt und durch manuelles Drehen die Verstellung des Seitenschiebers bewirkt.In a simple embodiment, a manually drivable transmission element is provided, which is accessible from outside the panel. In question, this is for example a spindle arrangement which extends laterally into the region of the covering or through it and causes the adjustment of the side slide by manual rotation.

Ein Getriebe ist generell für den Antrieb des Verstellwagens von Vorteil. Im Falle motorischer Antriebsmittel kann über ein Transmissionsgetriebe beispielsweise der Antriebsmotor mit Hilfe eines Transmissionsgetriebes vom Verstellwagen beabstandet angeordnet werden. Der Motor kann dementsprechend in einem Bereich der Schneidvorrichtung angeordnet werden, in dem ausreichend Platz vorhanden ist und der Motor ortsfest befestigbar ist, d. h. der Motor bewegt sich nicht mit dem Verstellwagen. Ein Getriebe kann auch als Übersetzungsgetriebe ausgebildet werden, um beispielsweise einen kleineren und damit kostengünstigeren Motor zu verwenden. Die vorgenannten Vorteile eines Getriebes sind auch beim Einsatz eines Arbeitszylinders an Stelle eines Antriebsmotors erhältlich.A gearbox is generally advantageous for driving the adjusting carriage. In the case of motor drive means, for example, the drive motor by means of a transmission gear from the adjusting carriage can be arranged via a transmission gear. Accordingly, the motor can be arranged in an area of the cutting device in which sufficient space is available and the motor can be fastened fixedly in place, ie. H. The engine does not move with the adjustment car. A transmission can also be designed as a transmission gear, for example, to use a smaller and thus cheaper engine. The aforementioned advantages of a transmission are also available when using a working cylinder instead of a drive motor.

Beim manuellem Betrieb wirkt das Getriebeelement zumindest als Transmissionsgetriebe, um die Kraft vom Ort des manuellen Antriebs an den Seitenschieber, beispielsweise über den Verstellwagen zu übertragen. Auch hier kann ein Untersetzungsgetriebe von Vorteil sein, um die manuelle Verstellung für eine Bedienperson zu erleichtern.In manual operation, the transmission element acts at least as a transmission gear to transmit the force from the location of the manual drive to the side shift, for example via the adjustment. Again, a reduction gear may be beneficial to facilitate manual adjustment for an operator.

Als Transmissionsgetriebe ist vorteilhafterweise auch ein Riemen- und/oder Kettengetriebe verwendbar, wodurch ein paralleler Versatz zwischen der Bewegungsachse des Verstellwagens und dem zugehörigen Antriebsmotor bzw. Antriebszylinder möglich ist. Auch für einen manuellen Antrieb ist über eine Riemen- und/oder Kettengetriebe ein entsprechender Versatz gegebenenfalls von Vorteil, um das manuelle Getriebeelement an einem geeigneten Ort in den von außen zugänglichen Bereich zu führen. Riemen- oder Kettengetriebe sind darüber hinaus geeignet, auch ein Übersetzungsgetriebe im obigen Sinne zu bilden, wobei hierzu bei Bedarf auch übliche Zahnradgetriebe verwendbar sind.As a transmission gear advantageously a belt and / or chain transmission is used, whereby a parallel offset between the axis of movement of the adjusting and the associated drive motor or drive cylinder is possible. Also, for a manual drive via a belt and / or chain transmission, a corresponding offset may be advantageous to guide the manual transmission element at a suitable location in the externally accessible area. Belt or chain transmission are also suitable to form a transmission gear in the above sense, for which purpose also customary gear transmission can be used.

Vorteilhafterweise wird zumindest für die manuelle Bedienung des Verstellwagens eine Stellwelle vorgesehen, die bis in einen von außerhalb der Verkleidung zugänglichen Bereich ragt. Diese Stellwelle kann beispielsweise die Verkleidung durchsetzen und außerhalb der Verkleidung ein Stellrad als Betätigungsorgan für die Stellwelle aufweisen. Es ist jedoch auch möglich, dass die Stellwelle oder allgemein das für die manuelle Bedienung vorgesehene Getriebeelement innerhalb der Verkleidung im Bereich einer Durchlassöffnung der Verkleidung endet und endseitig für den Angriff eines Betätigungswerkzeugs ausgebildet ist. Somit kann die Verstellung beispielsweise durch Einführen eines Werkzeugs, wie eines Steckschlüssels, durch eine Bohrung der Verkleidung über das entsprechende Getriebeelement, z.B. die genannte Stellwelle, durchgeführt werden.Advantageously, a control shaft is provided at least for the manual operation of the adjusting, which protrudes into a region accessible from outside the panel. This control shaft, for example, enforce the panel and outside the panel have a thumbwheel as an actuator for the control shaft. However, it is also possible that the actuating shaft or generally provided for manual operation gear element ends within the panel in the region of a passage opening of the panel and is formed at the end for the attack of an actuating tool. Thus, the adjustment may be accomplished, for example, by inserting a tool, such as a socket wrench, through a bore of the panel over the corresponding gear member, e.g. the aforementioned control shaft, are performed.

Antriebsorgane, wie ein Antriebsmotor und/oder ein Antriebszylinder können entweder unmittelbar mit dem Verstellwagen oder aber auch eingangsseitig über ein Getriebe mit dem Verstellwagen verbunden werden.Drive elements, such as a drive motor and / or a drive cylinder can be connected either directly to the adjustment or on the input side via a transmission with the adjustment.

Bei einer erfindungsgemäßen Schneidvorrichtung sind bei Bedarf auch mehrere Antriebsarten möglich. So ist es beispielsweise denkbar, eine manuelle Verstellmöglichkeit mit einer motorischen oder anderweitig angetriebenen Verstellung zu kombinieren. So kann beispielsweise eine Stellwelle einerseits für die manuelle Bedienung in den von außen zugänglichen Bereich geführt sein und zugleich über ein Transmissionsgetriebe mit einem Antriebsorgan wie einem Antriebsmotor verbunden werden. In einer solchen Anordnung kann die Bedienperson wahlweise manuell oder über das entsprechende Antriebsorgan die Verstellung durchführen. Auch bei einem Defekt des Antriebsorgans ist in diesem Fall immer noch eine manuelle Verstellmöglichkeit gegeben.In a cutting device according to the invention, if necessary, several drive types are possible. Thus, it is conceivable, for example, to combine a manual adjustment with a motorized or otherwise driven adjustment. Thus, for example, an actuating shaft can be guided on the one hand for manual operation in the externally accessible area and at the same time be connected via a transmission gear with a drive member such as a drive motor. In such an arrangement, the operator can either manually or via the corresponding drive member perform the adjustment. Even with a defect of the drive member a manual adjustment is still given in this case.

Vorteilhafterweise wird weiterhin eine Positionsanzeige für die aktuelle Position des Verstellwagens vorgesehen. Da erfindungsgemäß die Verstellung auch ohne Sichtkontakt zu dem Verstellwagen bzw. zu dem Seitenschieber möglich ist, hilft eine derartige Positionsanzeige für das Auffinden der aktuell gewünschten Arbeitsposition des Seitenschiebers.Advantageously, a position indicator for the current position of the adjusting provided. Since, according to the invention, the adjustment is also possible without visual contact with the adjusting carriage or with the side slide, such a position indicator helps to find the currently desired working position of the side slide.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand der Figuren nachfolgend näher erläutert.An embodiment of the invention is illustrated in the drawing and will be explained in more detail with reference to FIGS.

Die Vorrichtung 1 gemäß Figur 1 umfasst zwei Seitenschieber 2, 3, die jeweils auf einem Verstellwagen 4, 5 befestigt sind. Die Verstellwagen sind in einer Linearführung geführt.The device 1 according to FIG. 1 comprises two lateral slides 2, 3, which are each fastened on an adjusting carriage 4, 5. The adjustment cars are guided in a linear guide.

Das zu schneidende Produkt 6 wird kurz vor dem Frontbeschnitt durch ein Frontmesser 7 mittels der Seitenschieber 2, 3 positioniert. Ein Gegenmesser 8 ist in dieser dargestellten Position dementsprechend unterhalb des zu schneidenden Produkts angeordnet.The product 6 to be cut is positioned shortly before the front trimming by a front knife 7 by means of the side shifters 2, 3. A counter knife 8 is accordingly arranged below the product to be cut in this illustrated position.

Die Betätigung des Seitenschiebers 2, 3 erfolgt in der dargestellten Ausführungsvariante durch eine mechanische Kurve 9, die mit jedem Messerhub vertikal bewegt wird. Hierdurch erfährt eine korrespondierende Kurvenrolle 10 (vgl. Figur 5) eine horizontale Bewegung. Mit Hilfe von Zugfedern 24, 25 werden die Verstellwagen 4, 5 dabei mit ihren Kurvenrollen 10 gegen die Kurven 9 gezogen. Mit der Kurvenrollenachse sind zwei Lagerböcke 11, 12 und Wellen 13 starr verbunden. Im Lagerbock 11 ist eine Gewindespindel 14 gelagert. Über diese Gewindespindel 14 wird der Verstellwagen 4 und somit der Schieber 2 mitbewegt. Über diese Spindel 14 und der im Verstellwagen 4 befindlichen Gewindebuchse kann der Verstellwagen 4 demnach in seiner Position verstellt werden.The actuation of the side slide 2, 3 takes place in the illustrated embodiment by a mechanical curve 9, which is moved vertically with each knife stroke. As a result, a corresponding cam roller 10 (see Figure 5) undergoes a horizontal movement. With the help of tension springs 24, 25, the adjusting carriage 4, 5 are thereby pulled with their cam rollers 10 against the curves 9. With the cam roller axis two bearing blocks 11, 12 and shafts 13 are rigidly connected. In the bearing block 11 a threaded spindle 14 is mounted. About this threaded spindle 14 of the adjustment carriage 4 and thus the slider 2 is moved. By means of this spindle 14 and the threaded bushing located in the adjusting carriage 4, the adjusting carriage 4 can accordingly be adjusted in its position.

Die Verstellung erfolgt manuell über jedem Seitenschieber zugeordnete Handräder 15, 16. Mit den Handrädern 15, 16 drehen sich zwei als Profilwellen ausgebildete Stellwellen 17, 18. Über Formschluss werden somit mit den Stellwellen 17, 18 Antriebsräder 19, 20 bewegt, die horizontal fest am Seitenschiebergehäuse 21 befestigt sind. Die Kraftübertragung zur horizontal oszillierenden Gewindespindel 14 wird in dem dargestellten Fall jeweils durch einen flexiblen Zahnriemen 22, 23 übernommen.The adjustment is done manually via each side slider associated with hand wheels 15, 16. With the hand wheels 15, 16 two trained as a profile shaft adjusting shafts 17, 18 are about positive engagement thus with the control shafts 17, 18 drive wheels 19, 20 moves, the horizontal fixed on Sideshift housing 21 are attached. The power transmission to the horizontally oscillating threaded spindle 14 is in the case shown in each case by a flexible toothed belt 22, 23 taken.

Die Ausführungsform gemäß Figur 3 zeigt anstelle der Stellwellen 17, 18, zwei angeflanschte Antriebsmotoren 26, 27, die über nicht näher dargestellte Schalter von außerhalb der Verkleidung 28 zugänglich sind.The embodiment of Figure 3 shows instead of the control shafts 17, 18, two flanged drive motors 26, 27, which are accessible via switches not shown from outside the panel 28.

Figur 4 wiederum zeigt eine Kombination der beiden vorbeschriebenen Ausführungsvarianten, d.h. die Kombination mit Stellwellen 17, 18 und Antriebsmotoren 26, 27.Figure 4, in turn, shows a combination of the two embodiments described above, i. the combination with adjusting shafts 17, 18 and drive motors 26, 27th

In der dargestellten Ausführungsform gemäß den Figuren 1 und 4 sind mechanische Zähler 29, 30 vorgesehen, mittels der die Umdrehungen der Stellwellen 17, 18 gezählt und somit die Positionen der Seitenschieber 2, 3 erfasst werden. Die Zähler 29, 30 verfügen über eine Anzeige, so dass die Positionen dementsprechend von einer Bedienperson ablesbar sind.In the illustrated embodiment according to FIGS. 1 and 4, mechanical counters 29, 30 are provided by means of which the revolutions of the adjusting shafts 17, 18 are counted and thus the positions of the lateral slides 2, 3 are detected. The counters 29, 30 have a display, so that the positions are accordingly readable by an operator.

Die Ausführungsvariante gemäß Figur 6 zeigt entgegen den vorbeschriebenen Ausführungsvarianten einen Antriebsmotor 31, der über ein Zahnradgetriebe 32 mit dem Verstellwagen 33 verbunden ist. Die Verkleidung 34 ist in dieser Ausführungsvariante mit einer Bohrung 35 versehen, die groß genug für den Durchlass eines Werkzeugs 36, beispielsweise einem Steckschlüssel ist, der an dem Getriebezahnrad 37, beispielsweise an einer Außensechskantfläche des Getriebezahnrads 37 angreifen kann.Contrary to the previously described embodiments, the embodiment according to FIG. 6 shows a drive motor 31, which is connected to the adjustment carriage 33 via a toothed gearing 32. The lining 34 is provided in this embodiment with a bore 35 which is large enough for the passage of a tool 36, for example a socket wrench, which can engage the transmission gear 37, for example on an outer hexagonal surface of the transmission gear 37.

Die dargestellten Ausführungsvarianten zeigen verschiedene Möglichkeiten, wie die Seitenschieber einer erfindungsgemäßen Schneidvorrichtung über von außen zugängliche Betätigungsorgane verstellbar sind. Jede dieser Ausführungsvarianten erlaubt damit die Einstellung der Seitenschieberposition, ohne Öffnung der Verkleidung. Die Erfindung ermöglicht demnach eine wesentlich bedienerfreundlichere Ausführung einer Schneidvorrichtung gegenüber dem bisherigen Stand der Technik.The illustrated embodiments show various ways in which the side sliders of a cutting device according to the invention are adjustable by externally accessible actuators. Each of these variants thus allows the adjustment of the sideshift position, without opening the panel. The invention thus enables a much more user-friendly design of a cutting device over the prior art.
