Description

Die Erfindung betrifft eine Vorrichtung zur Begrenzung der Kraft, die auf einen Betätigungsmechanismus für eine Bindevorrichtung und/oder eine Loch-/Stanzvorrichtung ausgeübt wird, wobei der Betätigungsmechanismus aus einer drehbaren Achse besteht, die mit dem entsprechenden bewegbaren Teil der Binde- und/oder Loch-/Stanzvorrichtung derart gekoppelt ist, daß eine rotative Bewegung der Achse in eine translatorische Bewegung des entsprechenden bewegbaren Teils der Binde- und/oder Loch-/Stanzvorrichtung umgesetzt wird.The invention relates to a device for limiting the Force acting on an operating mechanism for a Binding device and / or a punching / punching device is exercised, the actuating mechanism from a rotatable axis, which corresponds to the corresponding movable part of the binding and / or punching / punching device is coupled such that a rotational movement of the axis in a translational movement of the corresponding movable part of the binding and / or punching / punching device is implemented.

Es sind eine Vielzahl von Verfahren bekannt geworden, um aus losen Blättern ein permanent gebundenes Dokument herzustellen. Die Verfahren beruhen entweder darauf, die Blätter an einer Seite mittels eines thermischen Klebers miteinander zu verbinden - sog. Thermisches Bindeverfahren - oder mittels mechanischer Binde-Elemente, wie Kammbinde-Elemente, Drahtbinde-Elemente oder Kanalbinde-Elemente. Bei der Verwendung von Kammbinde-Elementen oder Drahtbinde-Elementen müssen die losen Blätter zuerst gelocht werden. In Kammbinde- bzw. Drahtbindevorrichtungen ist daher üblicherweise ein Loch-/Stanzmechanismus integriert. Eine Drahtbinde-Vorrichtung ist z.B. aus der US-PS 4,482,279 bekannt geworden. Eine Kammbinde-Vorrichtung wird in der US-PS 4,613,266 und in der US-PS 4,872,796 beschrieben. In der US-PS 5,226,771 wird eine sog. Kanalbinde-Vorrichtung vorgestellt.A variety of methods have been known to a permanently bound document from loose sheets to manufacture. The procedures are based either on the Leaves on one side using a thermal adhesive to connect with each other - so-called thermal binding process - or by means of mechanical binding elements, such as comb binding elements, Wire tie elements or channel tie elements. At the use of comb binding elements or wire binding elements the loose sheets must be punched first. In comb binding or wire binding devices is therefore usually a hole / punch mechanism integrated. A Wire binding device is e.g. from U.S. Patent 4,482,279 known. A comb binding device is in the U.S. Patent 4,613,266 and U.S. Patent 4,872,796. In U.S. Patent 5,226,771 a so-called channel binding device is presented.

Bei Kammbinde- und Drahtbinde-Vorrichtungen mit integriertem Loch-/Stanzmechanismus werden während des Loch-/Stanzvorgangs relativ große Kräfte auf den Betätigungsmechanismus ausgeübt. Immer wieder kommt es vor, daß die maximale Belastbarkeit der beanspruchten Teile hierbei überschritten wird, weil das Bedienpersonal z.B. die vorgegebene maximale Anzahl von Blättern, die in einem Vorgang gelocht/gestanzt werden können, überschreitet oder weil anstelle von Papierbögen Karton- oder Plastikbögen gelocht/gestanzt werden. Um der zuerst genannten Gefahr entgegenzutreten, kann an der Vorrichtung eine Meßeinheit vorgesehen sein, die dem Bedienpersonal die maximal erlaubte Dicke eines zu lochenden/zu stanzenden Papierstapels anzeigt. Durch eine derartige Maßnahme wird jedoch nicht die zweite Gefahr beseitigt, daß in der Loch/Stanzvorrichtung andere Materialien als Papier in der erlaubten Dicke gelocht/gestanzt werden. Die Folge eines Überschreitens der maximal zulässigen Beanspruchung des Betätigungsmechanismus besteht in einem Verbiegen oder Brechen der über die Maßen beanspruchten Maschinenteile.With comb binding and wire binding devices with integrated punching / punching mechanism during the Punching / punching relatively large forces on the Actuating mechanism exercised. Again and again it happens that the maximum load capacity of the stressed parts is exceeded here because the operating personnel e.g. the specified maximum number of sheets in one Operation can be punched / punched, exceeds or because instead of paper sheets, cardboard or plastic sheets to be punched / punched. To the first mentioned danger to counteract, a measuring unit on the device be provided to the operating personnel the maximum allowed thickness of a hole to be punched / punched Displays stack of paper. Such a measure will however, does not eliminate the second risk that in the hole / punch materials other than paper in the permissible thickness can be punched / punched. The consequence of one Exceeding the maximum permissible stress on the Actuating mechanism consists of bending or Breaking of the machine parts that are overstressed.

Ähnlich ist die Lage, wenn in einer Kanalbinde-Vorrichtung Kanalelemente verwendet werden, die für die entsprechende Kanalbinde-Vorrichtung nicht geeignet sind. Auch hier kann es infolge von Überbeanspruchung der Vorrichtungsteile zu deren Zerstörung kommen.The situation is similar when in a duct binding device Channel elements are used for the corresponding Channel binding device are not suitable. Here too it due to overuse of the device parts their destruction are coming.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung vorzuschlagen, die begrenzt belastbare Teile einer Bindevorrichtung und/oder einer Loch-/Stanzvorrichtung vor Zerstörung schützt. The invention has for its object a device propose the limited resilient parts of a Binding device and / or a punching / punching device Destruction protects.

Die Aufgabe wird in Anspruch 1 dadurch gelöst, daß in dem Betätigungsmechanismus ein Kopplungsmechanismus vorgesehen ist, der bei Überschreiten einer auf den Betätigungsmechanismus ausgeübten, maximal zulässigen Kraft zerstört wird.The object is achieved in claim 1 in that in the actuating mechanism a coupling mechanism is provided which when exceeding one on the actuating mechanism exerted maximum permissible force destroyed becomes.

Dank der erfindungsgemäßen Lösung ist bei Nutzung der Binde- und/oder der Loch-/Stanzvorrichtung nicht mehr die bessere Einsicht des Bedienpersonals erforderlich, sowie z.B. in dem Dokument "Akademischen Verein Hütte; Hütte des Ingenieurs Taschenbuch; Maschinenbau Teil A; 1954; Verlag von Wilhelm Ernst & Sohn; Berlin; Seite 122". Die erfindungsgemäße Lösung geht auch nicht den Weg, die Materialien für die beanspruchten Teile derart zu optimieren, daß sie selbst höchsten Beanspruchungen noch standhalten können; eine derartige Lösung wäre viel zu kostspielig.Thanks to the solution according to the invention when using the Binding and / or the punching / punching device no longer the better understanding of the operating personnel is required, as well as e.g. in the document "Academic association hut; hut of the engineer paperback; mechanical engineering part A; 1954; publisher of Wilhelm Ernst &Son;Berlin; page 122". The solution according to the invention does not go the way that Materials for the claimed parts too optimize that they can handle even the highest demands can withstand; such a solution would be much too expensive.

Die erfindungsgemäße Lösung in Anspruch 1 geht vielmehr einen von den bekannt gewordenen Möglichkeiten abweichenden Weg: Sie integriert in den Betätigungsmechanismus einen Kopplungsmechanismus, der bei Überschreiten der maximal zulässigen Beanspruchung zerstört wird. Bei Überbeanspruchung müssen in Zukunft also nicht mehr wesentliche, i.a. recht teuere und schwer zu installierende Maschinenteile ausgewechselt werden, sondern im ungünstigsten Fall muß lediglich ein billiges Sollbruch-Teil ersetzt werden, dessen Auswechselung durch das Bedienpersonal erfolgen kann.The solution according to the invention in claim 1 is rather one of the Opportunities known alternative path: you integrates one into the operating mechanism Coupling mechanism which, when the maximum is exceeded permissible stress is destroyed. At Overuse will no longer be necessary in the future essential, generally quite expensive and difficult to install Machine parts are replaced, but in the In the worst case, only a cheap predetermined breaking part must be used to be replaced, the replacement of which by the Operating personnel can take place.

Da der Kopplungsmechanismus immer dann zerstört wird, wenn das Bedienpersonal die maximal zulässige Beanspruchung der Loch-/Stanzvorrichtung überschreitet, hat die erfindungsgemäßen Lösung darüber hinaus ein Lerneffekt.Because the coupling mechanism is destroyed whenever that Operating personnel the maximum permissible load of the Punching / punching device has the solution according to the invention also a learning effect.

Gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß der Betätigungsmechanismus für die Binde- und/oder Loch/Stanzvorrichtung einen Hebel aufweist, der mit der drehbaren Achse verbunden ist. According to an advantageous development of the The device according to the invention provides that the Actuation mechanism for the binding and / or hole / punching device has a lever which with the rotatable axis is connected.

Eine weitere Möglichkeit sieht vor, die Binde- und/oder Loch-/Stanzvorrichtung elektrisch zu betreiben. In diesem Fall weist der Betätigungsmechanismus für die Binde- und/oder Loch-/Stanzvorrichtung einen Motor auf, der die drehbare Achse antreibt. Eine elektrische Drahtkamm-Bindemaschine ist übrigens schon aus der US-PS 5,452,980 bekannt geworden.Another possibility provides for the binding and / or Hole / punch device to operate electrically. In this Case the actuating mechanism for the binding and / or punching / punching device a motor that the rotatable axis drives. An electric wire comb binding machine is already from US Pat. No. 5,452,980 known.

Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Vorrichtung besteht der Kopplungsmechanismus aus einem Stift, der die Verbindung zwischen dem Motor bzw. dem Hebel und der drehbaren Achse herstellt und der bei Überschreiten einer maximalen zulässigen Kraft bricht. In diesem Fall muß also der Kopplungsmechanismus ersetzt werden.According to an advantageous embodiment of the device according to the invention there is Coupling mechanism from a pin that connects between the motor or the lever and the rotatable axis manufactures and that when a maximum is exceeded permissible force breaks. In this case, the Coupling mechanism to be replaced.

Die Aufgabe wird in Anspruch 5 dadurch gelöst, daß in dem Betätigungsmechanismus ein Kopplungsmechanismus vorgesehen ist, der aus folgenden Teilen besteht: einer Ausnehmung im Endbereich der drehbaren Achse, in dem ein Motor bzw. ein Hebel angreift; in dem Verbindungsstück zwischen Motor und drehbarer Achse bzw. Hebel und drehbarer Achse ist ein Hohlraum zur Aufnahme einer Feder vorgesehen; die Kopplung zwischen drehbarer Achse und Motor bzw. Hebel wird über ein Kontaktelement erzielt, das bei vorschriftsmäßiger Betätigung der Binde- und/oder Loch-/Stanzvorrichtung in die Ausnehmung eingreift und bei Überschreiten der maximal zulässigen Kraft auf den Betätigungsmechanismus aus der Ausnehmung herausspringt, so daß der Motor bzw. der Hebel von der drehbaren Achse entkoppelt ist.The object is achieved in claim 5 in that a coupling mechanism is provided in the actuating mechanism from the following Share consists of: a recess in the end area of the rotatable axis in which a motor or a lever engages; in the connector between the motor and the rotating axle or lever and rotatable axis is a cavity for Inclusion of a spring provided; the coupling between rotatable axis and motor or lever is over a Contact element achieved that with proper Actuation of the binding and / or punching / punching device in the Recess engages and when the maximum is exceeded permissible force on the actuating mechanism from the Recess pops out, so that the motor or the lever is decoupled from the rotatable axis.

Gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung wird vorgeschlagen, daß es sich bei der Ausnehmung um eine rillenförmige Vertiefung und bei dem Kontaktelement um eine Kugel handelt.According to an advantageous development of the Device according to the invention is proposed that it the groove is a groove-shaped depression and the contact element is a ball.

Im gezeigten Falle ist der bewegbare Teil 15 eine Metallplatte, aus der einzelne Messer herausgestanzt sind. Um die Kosten für die Herstellung der Loch-/Stanzvorrichtung möglichst gering zu halten, sind Hebel 5, drehbare Achse 6 und Lochplatte 15 nur für gewisse, eine Obergrenze nicht überschreitende Belastungen ausgelegt. Um eine Zerstörung der Elemente bei zu hohen Belastungen auszuschließen, ist zwischen Hebel 5 und drehbarer Achse 6 ein Kopplungsmechanismus 4 vorgesehen. Dieser Kopplungsmechanismus besteht im dargestellten Fall aus einem Stift 8, der als Sollbruchstelle ausgebildet ist. Dies wird entweder durch die Wahl eines entsprechenden Materials oder durch entsprechende mechanische Bearbeitung des Stifts 8 (z.B. eine Rille oder Kerbe) erreicht.Fig. 1 shows a partial perspective view of a first Design of the device according to the invention in a Punching / punching device 1.

Er besteht aus einer Kugel 13, die durch eine Feder 12 in einer entsprechend geformten Ausnehmung 10 der drehbaren Achse 6 gelagert ist. Die Feder 12 ist in dem Hohlraum 11 des Hebels 5 angeordnet. Überschreitet die auf den Betätigungsmechanismus 14 ausgeübte Kraft die maximal zulässige Kraft, für die die einzelnen Teile der Vorrichtung ausgelegt sind, so wird die Reibungskraft der Kugel 13 in der Ausnehmung 10 überwunden. Der Kopplungsmechanismus 4 entkoppelt, wodurch der Loch/Stanzvorgang unterbrochen wird. Sobald die Kraft nicht mehr an dem Hebel 5 angreift, geht der Kopplungsmechanismus 4 wieder in die Ausgangslage zurück, wenn der Hebel 5 in seine Ausgangslage zurückbewegt wird.2 is a partial perspective view of a second embodiment of the device according to the invention a punching / punching device 1 can be seen. The The device according to the invention here consists of a Mechanism that decouples when overused. This Coupling mechanism 4 is self-healing. He consists of a ball 13 by a spring 12 in a correspondingly shaped recess 10 of the rotatable Axis 6 is mounted. The spring 12 is in the cavity 11 the lever 5 arranged.
