Die vorliegende Erfindung betrifft eine Heftvorrichtung zur Erzeugung von Heftdrahtklammern, insbesondere Ringösenheftklammern, zum Heften von gestapelten blattförmigen Materialien gemäß dem Oberbegriff von Anspruch 1.The present invention relates to a stapling device for producing stapling wire staples, in particular eyelet stapling staples, for stapling stacked sheet-like materials according to the preamble of claim 1.

Derartige Heftvorrichtungen werden insbesondere in Sammelheftern zur Erzeugung von sammelgehefteten Broschuren, etwa Zeitschriften, verwendet. Entsprechend sind derartige Heftvorrichtungen beispielsweise aus der Deutschen Patentschrift DE 44 44 220 oder aus der Deutschen Offenlegungsschrift DE 197 12 876 bekannt. Insbesondere werden gattungsgemäße Heftvorrichtungen wie in Fig. 1 gezeigt von der Hohner Maschinenbau GmbH vertrieben.Such stapling devices are used in particular in saddle stitchers for the production of saddle-stitched brochures, such as magazines. Accordingly, such stapling devices are for example from the German Patent DE 44 44 220 or from the German Offenlegungsschrift DE 197 12 876 known. In particular, generic stapling devices as in Fig. 1 shown distributed by Hohner Maschinenbau GmbH.

Dabei handelt es sich um eine Heftvorrichtung 100 zur Erzeugung von Heftdrahtklammern, insbesondere Ringösenheftklammern, zum Heften von gestapelten blattförmigen Materialien, mit einem Heftkopfgrundkörper 5, wobei der Heftkopfgrundkörper 5, einen Treiber 80 aufweist, zum Eintreiben der Heftdrahtklammer in die gestapelten blattförmigen Materialien in einer Abwärtsbewegung des Treibers 80, sowie einem Former 60 zum Formen der Heftdrahtklammern, insbesondere Ringösenheftklammern, wobei bei der Abwärtsbewegung des Treibers 80 der Former 60 ausgeschwenkt wird, sowie einem Drahtklemmhebel 63, wobei der Drahtklemmhebel verschwenkbar im Former 60 gelagert ist. Überdies weist der Former 60 einen Stützhebel 61 auf, an dessen Ende eine Rolle 62 drehbar gelagert ist, wobei die Rolle bei der Aufwärtsbewegung des Treibers 80 an spezifischen Kurvenflächen am Treiber entlangläuft, so dass dadurch der Former 60 in der Aufwärtsbewegung des Treibers 80 gestützt wird, so dass das Einschwenken des Formers 60 in der Aufwärtsbewegung zu einem anderen Punkt als das Ausschwenken des Formers 60 in der Abwärtsbewegung erfolgt. Der Stützhebel 61 und die Rolle 62 sind mit einer nicht gezeigten Feder an dem Former 60 vorgespannt. Bei der Aufwärtsbewegung des Treibers darf der Former 60 noch nicht einschwenken, damit der Heftdraht 1 für die Bildung der nächsten Heftklammer wieder vorgeschoben und abgeschnitten werden kann.This is a stapling device 100 for producing staple staples, in particular eyelet staples, for stapling stacked sheet materials, with a stapling head body 5, wherein the stapling head body 5, a driver 80 for driving the staple staple in the stacked sheet materials in a downward movement the driver 80, and a former 60 for forming the stitching wire staples, in particular Ringösenheftklammern, wherein during the downward movement of the driver 80 of the former 60 is pivoted, and a wire clamping lever 63, wherein the wire clamping lever is pivotally mounted in the former 60. Moreover, the former 60 has a support lever 61 at the end of which a roller 62 is rotatably supported, the roller running along specific curves on the driver during the upward movement of the driver 80, thereby supporting the former 60 in the upward movement of the driver 80 so that the swerving of the former 60 in the upward movement to a point other than the swinging of the former 60 in the downward movement takes place. The support lever 61 and the roller 62 are biased by a spring, not shown, on the former 60. During the upward movement of the driver, the former 60 must not yet pivot in, so that the stitching wire 1 can be advanced again and cut off for the formation of the next staple.

Dieser Aufbau hat den Nachteil, das er aufwendig, störanfällig und lärmintensiv ist. Es wäre aber wünschenswert, eine Heftvorrichtung zur Verfügung zu haben, die einfach, störungsarm und vergleichbar leise arbeitet. Daher ist es die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Heftvorrichtung zur Erzeugung von Heftdrahtklammern, insbesondere Ringösenheftklammern, zum Heften von gestapelten blattförmigen Materialien zu schaffen, die einfach, störungsarm und vergleichbar leise arbeitet.This structure has the disadvantage that it is expensive, prone to failure and noisy. However, it would be desirable to have a stapler available that works simple, low-interference and comparatively quiet. Therefore, it is the object of the present invention to provide a generic stapling device for the production of stitching staples, in particular Ringösenheftklammern to staple stacked sheet-like materials that works simple, low-interference and comparatively quiet.

Diese Aufgabe wird mit einer Heftvorrichtung mit den Merkmalen des kennzeichnenden Teils von Anspruch 1 gelöst.This object is achieved with a stapling device having the features of the characterizing part of claim 1.

Demnach weist die erfindungsgemäßen Heftvorrichtung an dem Drahtklemmhebel ein Steuerelement auf, dass in Wechselwirkung mit einer Steuerfläche den gewünschten Bewegungsablauf realisiert. Dadurch entfällt der zusätzliche, durch Federkraft bewegte, drehbar gelagerte und mit einer Rolle versehene Stützhebel, wodurch die gewünschten Vorteile erzielbar sind. Da der Gesamtaufbau deutlich weniger bewegliche Teile aufweist und der Drahtklemmhebel durch den Steuerbolzen eine zusätzliche Aufgabe übernimmt ist die erfindungsgemäße Heftvorrichtung mithin einfacher und auch störungsärmer. Zudem werden die zuvor erforderlichen spezifischen Kurvenflächen in einem Steuerblock zusammengefasst. Insgesamt wird der Aufbau dadurch auch in der Montage kostengünstiger. Auch die Geräuschentwicklung kann durch die verringerte Teilezahl verringert werden. Im Übrigen ist die erfindungsgemäße Heftvorrichtung auch Platz sparender, da die zusätzlichen Teile im Raum zwischen dem Former und dem Treiber entfallen.Accordingly, the stapling device according to the invention on the wire clamping lever on a control that realizes the desired movement in interaction with a control surface. This eliminates the additional, moved by spring force, rotatably mounted and provided with a roller support lever, whereby the desired benefits can be achieved. Since the overall structure has significantly fewer moving parts and the wire clamping lever assumes an additional task by the control bolt, the stapling device according to the invention is consequently simpler and also less prone to interference. In addition, the previously required specific cam surfaces are combined in a control block. Overall, the structure is thereby cheaper in the assembly. The noise can be reduced by the reduced number of parts. Incidentally, the stapling device according to the invention is also space-saving, since the additional parts in the space between the former and the driver accounts.

Erfindungsgemäß handelt es sich bei dem Steuerelement um einen Steuerbolzen, der vorteilhafterweise entlang einer Steuerkurve, bestehend aus mehreren Steuerkurvenabschnitten, die in einem Steuerblock ausgebildet ist geführt wird, wobei der Steuerblock an einem Schieber im Heftkopfgrundkörper angeordnet ist. Vorteilhafterweise ist der Former durch eine nicht gezeigte Druckfeder gegen den Steuerblock vorgespannt.According to the invention, the control element is a control bolt, which is advantageously guided along a control cam, comprising a plurality of control cam sections, which is formed in a control block, wherein the control block is arranged on a slide in the stapling head base body. Advantageously, the former is biased by a compression spring, not shown, against the control block.

Die in den Figuren 2 bis 4 dargestellte Ausführungsform der erfindungsgemäßen Heftvorrichtung 100 beschränkt sich auf die Darstellung und Beschreibung von erfindungswesentlichen Details. Weitere für den Betrieb der Heftvorrichtung 100 erforderlichen Elemente, wie Führung, Steuerung, Antriebe, Befestigungsmittel usw., die sich insbesondere auch nicht vom Stand der Technik unterscheiden oder dem entlehnt sind, werden nicht weiter beschrieben und / oder zur Verdeutlichung weggelassen.The in the FIGS. 2 to 4 illustrated embodiment of the stapling device 100 according to the invention is limited to the representation and description of essential to the invention details. Further necessary for the operation of the stapling device 100 elements such as guide, control, drives, fasteners, etc., which in particular also do not differ from the prior art or are borrowed, are not further described and / or omitted for clarity.

In Fig. 2 ist eine bevorzugte Ausführungsform der erfindungsgemäßen Heftvorrichtung 100 gezeigt. Der Heftkopfgrundkörper 5 ist mit einer Aufnahmeschiene 8 fest verbunden. Zusätzlich zur seitlichen Verschiebung der Aufnahmeschiene 8 werden die Steuerschienen 9, 10 vertikal bewegt. Durch die Überlagerung dieser Bewegungen werden über den Umbiegerschieber 32 und den Treiberschieber 33 die übrigen Bewegungen der Heftvorrichtung abgeleitet. An dem Heftkopfgrundkörper ist ein Abschneidkasten 20 angeordnet, in den der Heftdraht 1 in Fig. 2 von links eingeführt wird und entsprechend der erforderlichen Drahtlänge abgeschnitten wird. Dabei hängt die erforderliche Drahtlänge z.B. von der Dicke des Stapels der geheftet werden soll ab, sowie von der Art der Drahtheftung, also etwa Ringösenheftung oder normale Klammerheftung. Allerdings können die gattungsgemäßen Heftvorrichtungen 100 typischerweise nur jeweils eine Art der Heftung durchführen.In Fig. 2 a preferred embodiment of the stapling device 100 according to the invention is shown. The stapling head base body 5 is fixedly connected to a receiving rail 8. In addition to the lateral displacement of the receiving rail 8, the control rails 9, 10 are moved vertically. By superimposing these movements, the other movements of the stapling device are derived via the Umbiegerschieber 32 and the drive slide 33. At the Heftkopfgrundkörper a Abschneidkasten 20 is arranged, in which the stitching wire 1 in Fig. 2 is inserted from the left and cut off according to the required wire length. The required wire length depends, for example, on the thickness of the stack to be stapled, as well as on the type of wire stitching, such as ring-stitching or normal stapling. Indeed For example, the generic stapling devices 100 typically only perform one type of stapling at a time.

Damit der abgeschnittene Heftdraht 1 nicht herunterfällt, wird der Heftdraht von einer Klemmbacke 66 (vergleiche Fig. 3) die von einem Drahtklemmhebel 63 betätigt wird an dem Former 60 festgeklemmt. Der Former 60 wird derart kurvengesteuert, dass er das abgeschnittene Heftdrahtstück 1 in eine gewünschte Heftklammerform mit geöffneten Klammerschenkeln vorformt, also etwa zu einer Ringöse oder einer normalen Heftklammer. Diese vorgeformte Heftklammer wird dann mittels des Treibers 80 in den Stapel eingetrieben. Auf der Rückseite des Stapels ist ein nicht gezeigter, dem Fachmann bekannter Umbieger angeordnet, der die Heftklammer schließt, wobei der Umbieger allerdings nicht Teil der erfindungsgemäßen Vorrichtung 100 ist.So that the cut stitching wire 1 does not fall off, the stitching wire from a jaw 66 (see Fig. 3 ) which is operated by a wire clamping lever 63 is clamped to the former 60. The former 60 is cam-controlled so as to preform the cut-off stitching wire piece 1 into a desired staple form with the staple legs open, such as a ring eyelet or a normal staple. This preformed staple is then driven by the driver 80 into the stack. On the back of the stack, a not shown, known in the art Umbieger is arranged, which closes the staple, but the Umbieger is not part of the device 100 according to the invention.

Der Former 60 übergibt die vorgeformte Heftklammer an den Treiber 80. Dazu muss nun einerseits für die Abwärtsbewegung des Treibers 80 die Heftklammer freigegeben sein und andererseits der Former 60 aus dem Weg des Treibers 80 ausgeschwenkt werden. Dies wird nun auf erfinderische Weise allein mittels des Steuerbolzens 65 erzielt, der an dem Drahtklemmhebel 63 angeordnet ist und mit der Steuerkurve 72 des Steuerblocks 70 wechselwirkt, wie Fig. 3 und Fig. 4 gezeigt. Der Steuerblock 70 ist an dem Umbiegerschieber 32 angeordnet und wird mit dem Umbiegerschieber 32 in vertikaler Richtung auf und ab bewegt. Der Former 60 ist gerätefest mit dem Heftkopfgrundkörper 5 verschwenkbar verbunden.The former 60 transfers the preformed staple to the driver 80. For this purpose, the staple must now be released on the one hand for the downward movement of the driver 80 and on the other hand the former 60 must be swung out of the way of the driver 80. This is achieved in an inventive way solely by means of the control pin 65, which is arranged on the wire clamping lever 63 and interacts with the control cam 72 of the control block 70, such as Fig. 3 and Fig. 4 shown. The control block 70 is arranged on the Umbiegerschieber 32 and is moved with the Umbiegerschieber 32 in the vertical direction and down. The former 60 is fixedly connected to the stapling head base body 5 so as to be pivotable.

Bei der Abwärtsbewegung des Treibers 80 befindet sich der Steuerbolzen 63 in der in Fig. 3 linken Nut der Steuerkurve 72 in dem Steuerblock 70. Der Drahtklemmhebel 63 klemmt den abgeschnittenen und geformten Heftdraht 1. Wird der Treiber 80 weiter abwärts bewegt kommt der Steuerbolzen 63 mit der diagonalen Steuerkurve 73 in Kontakt. Diese bewirkt aufgrund der Federkraft der Feder 64, dass die Klemmbacke 66 geschlossen bleibt, aber der ganze Former 60 nach außen ausgeschwenkt wird, so dass es zu keiner Kollision zwischen dem Former 60 und dem Treiber 80 kommt. Schließlich ist der Treiber 60 und der Steuerblock 70 so weit abgesenkt, dass der Steuerbolzen 65 mit der horizontalen Steuerfläche 74 in Kontakt kommt, die die Klemmbacke 66 nun öffnet. Zu diesem Zeitpunkt hat der Treiber 80 die Heftklammer übernommen und treibt sie in den Stapel ein. Bei der folgenden Aufwärtsbewegung gleitet der Steuerbolzen 63 auf der rechten vertikalen Steuerfläche 75 des Steuerblocks 70 ab und verhindert so, dass der Former 60 eingeschwenkt wird, bevor wieder neuer Heftdraht 1 vorgeschoben wird, um eine neue Heftklammer zu formen.During the downward movement of the driver 80, the control pin 63 is in the in Fig. 3 The wire clamp lever 63 clamps the cut and formed stitching wire 1. When the driver 80 is further moved downward, the control pin 63 comes into contact with the diagonal cam 73. This causes due to the spring force of the spring 64 that the jaw 66 remains closed, but the entire former 60 is swung outwardly, so that there is no collision between the former 60 and the driver 80. Finally, the driver 60 and the control block 70 is lowered so far that the control pin 65 comes into contact with the horizontal control surface 74, which now opens the clamping jaw 66. To At this point driver 80 has taken over the staple and drives it into the stack. In the following upward movement, the control pin 63 slides on the right vertical control surface 75 of the control block 70, thus preventing the former 60 from being swung in before new staple wire 1 is advanced again to form a new staple.

Die erfindungsgemäße Heftvorrichtung kann in allen Heftvorrichtungen eingesetzt werden, nicht nur bei Sammelheftern, sondern auch bei Kopierern oder digitalen Druckern oder anderen Vorrichtung der Druckweiterverarbeitung, aber auch bei der Herstellung von Heftklammern in der Holz- oder Metallverarbeitung oder bei der Möbelherstellung, etwa bei der Herstellung von Bilderrahmen oder dergleichen.The stapling device according to the invention can be used in all stapling devices, not only saddle stitchers, but also in copiers or digital printers or other device of the print finishing, but also in the production of staples in the wood or metal processing or furniture manufacturing, such as in the production from picture frames or the like.
