Description

Die Erfindung betrifft einen Arbeitsorgane und/oder Steuereinrichtungen enthaltenden Bogentrenner in bogenverarbeitenden Maschinen, wobei der Bogentrenner mindestens Arbeitsorgane zum Erfassen, Trennen und Fördern sowie Steuerorgane zum Zuführen von einem das Erfassen, Trennen und Fördern der Bogen unterstützenden Blas- und/oder Saugluftstroms aufweist. Solch ein Bogentrenner ist aus der DE-A-196 01 470 bekannt, die den nächstliegenden Stand der Technik darstellt.
Derartige Bogentrenner sind allgemein üblich. Die in den Bogentrennem vorgesehenen Arbeitsorgane wie z.B. Trennsauger, Transportsauger oder ein Tasterfuß werden durch mechanische Getriebe im Takt der nachgeordneten bogenverarbeitenden Maschine mittels eintourig umlaufender Antriebswellen angetrieben (DE 19 601 470 A1, 19 522 901 C1, 43 12 228 A1). Die Steuerung des das Erfassen, Trennen und Fördern des bogenförmigen Materials unterstützenden Saug- oder Blasluftstroms erfolgt mittels Ventileinheiten, die mechanisch mit dem Antrieb der Arbeitsorgane verknüpft sind (DE 42 15 226 C2). Der Antrieb des Bogentrenners als funktionelle Einheit erfolgt mittels einer mechanischen Kopplung mit der nachgeordneten bogenverarbeitenden Maschine oder durch einen Elektromotor, der mittels einer elektrischen Welle mit der bogenverarbeitenden Maschine verknüpft ist (DE 41 02 472 A1).The invention relates to a sheet separator in sheet processing machines containing working elements and / or control devices, the sheet separator having at least working elements for detecting, separating and conveying, and control elements for supplying a blowing and / or suction air flow that supports the detecting, separating and conveying of the sheets. Such a sheet separator is known from DE-A-196 01 470, which represents the closest prior art.
Such sheet separators are common. The working elements provided in the sheet separators, such as separating suction, transport suction or a button foot, are driven by mechanical gears in time with the downstream sheet-processing machine by means of single-speed rotating drive shafts (DE 19 601 470 A1, 19 522 901 C1, 43 12 228 A1). The control of the suction or blown air flow supporting the detection, separation and conveyance of the sheet material is carried out by means of valve units which are mechanically linked to the drive of the working elements (DE 42 15 226 C2). The sheet separator as a functional unit is driven by means of a mechanical coupling with the downstream sheet-processing machine or by an electric motor which is linked to the sheet-processing machine by means of an electric shaft (DE 41 02 472 A1).

Nachteilig ist, unabhängig davon, ob der Antrieb der funktionellen Einheit Bogentrenner durch einen Elektromotor oder mittels einer mechanischen Kopplung erfolgt, daß die Arbeitsorgane und/oder die Steuerorgane des Bogentrenners in ihrer Zuordnung zueinander nicht frei wählbar sind. Sie sind mechanisch starr synchronisiert. Das bedeutet aber, da in bogenverarbeitenden Maschinen bogenförmiges Material unterschiedlichster Qualität und Grammatur zur Verarbeitung gelangt und dieses Material mit unterschiedlichster Geschwindigkeit verarbeitet wird, daß für Übernahme-/Übergabevorgänge, um in jedem Fall eine störungsfreie Arbeitsweise des Bogentrenners zu sichern, große Rastbereiche über den Drehwinkel der bogenverarbeitenden Maschine vorgesehen werden müssen. Das bedeutet aber auch, daß die den Arbeitsorganen bzw. Steuerorganen zugeordneten Mechanismen nicht nach kinematischen Gesichtspunkten optimiert werden können, so daß die Leistungsfähigkeit der Bogentrenner und damit der nachgeordneten bogenverarbeitenden Maschine nicht gesteigert werden kann.
Darüber hinaus ist es von Nachteil, daß zur Umsetzung der den Arbeitsorganen zugeordneten Arbeitsaufgaben mindestens jedem Arbeitsorgan ein Kurvengetriebe zugeordnet ist, wobei zusätzlich diesen Kurvengetrieben weitere, mitunter vielgliedrige Hebelmechanismen nachgeordnet sind, was insgesamt einen hohen Aufwand erfordert. It is a disadvantage, regardless of whether the functional unit sheet separator is driven by an electric motor or by means of a mechanical coupling, that the working members and / or the control members of the sheet separator cannot be freely selected in their assignment to one another. They are mechanically rigidly synchronized. However, this means that in sheet-processing machines sheet-shaped material of the most varied quality and grammage is processed and this material is processed at the most varied of speeds, that for take-over / transfer operations to ensure trouble-free operation of the sheet separator, large rest areas over the angle of rotation of the sheet processing machine must be provided. However, this also means that the mechanisms assigned to the work organs or control organs cannot be optimized from a kinematic point of view, so that the performance of the sheet separators and thus the downstream sheet-processing machine cannot be increased.
In addition, it is disadvantageous that at least each work organ is assigned a cam mechanism to implement the work tasks assigned to the work organs, with further, sometimes multi-element lever mechanisms being arranged downstream of these cam mechanisms, which overall requires a great deal of effort.

Aufgabe der Erfindung ist es, einen Bogentrenner zu schaffen, der sich mit einfachen Mitteln realisieren läßt und eine hohe Leistung ermöglicht.The object of the invention is to provide a sheet separator that can be done with simple means realizes and enables high performance.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Zuordnung der einzelnen Arbeitsorgane eines Bogentrenners und/oder die einen Blas- oder Saugluftstrom steuemden Mittel in Abhängigkeit vom jeweiligen Betriebszustand der bogenverarbeitenden Maschine sowie vom zur Verarbeitung gelangenden Material erfolgen kann, wodurch eine Leistungssteigerung des Bogentrenners möglich ist. Die Maßnahme, für jedes Arbeitsund/Oder Steuerorgan jeweils einen Antrieb bzw. für jede Teilbewegung einen Teilantrieb vorzusehen, wobei die Antriebe/Teilantriebe entsprechend der in einem Arbeitsdiagrammspeicher abgelegten Arbeitsdiagramme angesteuert werden, gestattet es, die den Arbeitsorganen vorgeordneten Übertragungsglieder einfach auszugestalten, was eine kostengünstige Fertigung ermöglicht. Darüber hinaus ist es möglich, die Arbeitsorgane mittels Arbeitsdiagrammen, die entsprechend der Arbeitsgeschwindigkeit und hinsichtlich der zur Verarbeitung gelangenden Materialien modifiziert sind, anzusteuern, wodurch eine weitere Leistungssteigerung des Bogentrenners ermöglicht wird.The advantages achieved with the invention are in particular that the assignment of individual working elements of a sheet separator and / or a blowing or suction air flow controlling means depending on the respective operating state of the sheet processing Machine as well as the material to be processed can be done, which means a Performance increase of the sheet separator is possible. The measure for every job and / or Control unit one drive or a partial drive for each partial movement to be provided, the drives / partial drives corresponding to those in a work diagram memory stored work diagrams are controlled, which allows the work organs upstream transmission links easy to design, which is an inexpensive Manufacturing enables. In addition, it is possible to use the work diagrams, which according to the speed of work and in terms of processing incoming materials are modified to control, thereby further increasing performance of the sheet separator is made possible.

    • In Figur 1 ist ein Bogenanleger 1 mit einem Bändertisch 2, einem Anlegtisch 3 und diesem zugeordnet Vordermarken 4 sowie Seitenmarken 5 dargestellt. Der Bändertisch 2 weist ein Tischblech 17 sowie sich quer zu einer Bogenförderrichtung 11 erstreckende Bänderwalzen 12, 13 auf. Die Bänderwalzen 12, 13 werden von mindestens zwei Transportbändern 14 umschlungen, die durch Umlenkrollen 15 und Spannrollen 16 geführt werden. Die Transportbänder 14 werden z.B. mittels der Bänderwalze 12 oder 13 in Umlaufrichtung 18 angetrieben. Mit der dem Bogenanleger 1 zugewandten Bänderwalze 12 korrespondiert eine Taktwalze 19, die im Maschinentakt gegen die Bänderwalze 12 gesteuert wird.
    Dem Anlegtisch 3 schließt sich eine Schwinganlage 20 und dieser nachgeordnet die Anlegtrommel 21 eines nicht dargestellten Druckwerkes an.
    Im Bogenanleger 1 ist ein Bogentrenner 6 mit Trennsaugern 7 und Transportsaugern 8 vorgesehen. Im Bogenanleger 1 ist weiterhin ein aus Bogen 9 bestehender Bogenstapel 10 angeordnet. Der Bogentrenner 6 ist als funktionale Einheit ausgebildet und kann neben den im Ausführungsbeispiel dargestellten Arbeitsorganen Trenn- und Transportsauger 6, 7 weitere Arbeitsorgane wie z.B. einen Tasterfuß oder Steuerorgane zum Zuführen von einem das Erfassen, Trennen, und Fördern der Bogen 9 unterstützenden Blas- und/oder Saugluftstromes enthalten. Dabei sind im Bogentrenner 6 neben den Arbeits- und Steuerorganen die diesen zugeordneten, zur Realisierung der Arbeitsaufgabe erforderlichen, ungleichmäßige Bewegungen erzeugenden Übertragungsglieder angeordnet. Am Bogentrenner 6 sind weiterhin separate Antriebe 22, 23, 26 vorgesehen, wobei für jedes Arbeitsorgan oder Steuerorgan mindestens ein separater Antrieb 22, 23, 26 vorgesehen ist. So ist im Ausführungsbeispiel den Trennsaugern 7 der Antrieb 22, den Transportsaugem 8 der Antrieb 23 und einer Steuereinrichtung 27 der Antrieb 26 zugeordnet. Dabei können die Antriebe 22, 23, 26 aus separat steuerbaren Teilantrieben bestehen, was beim Antrieb 23 der Transportsauger 7 durch das Vorsehen von z.B. zwei Teilantrieben 23.1 und 23.2 dargestellt ist. Durch das Vorsehen mehrerer Teilantriebe ist es möglich, z.B. das jeweilige Arbeitsorgan auf einer Bahnkurve mit mehreren Freiheitsgraden zu führen.
    Die Antriebe 22, 23.1, 23.2, 26 können als Linearantriebe oder Stellmotore ausgebildet sein, wobei insbesondere Drehstromservomotore vorgesehen werden. So sind die Antriebe 22, 23 als Drehstromservomotore 28, 29 sowie der Teilantrieb 23.1 als Drehstromservomotor 30 und der Teilantrieb 23.2 z.B. als Linearmotor 31 ausgebildet. Die Antriebe 22, 26 und die Teilantriebe 23.1, 23.2 sind mit einer Steuereinheit 24 verbunden, die unter Einbeziehung von Taktsignalen der nachgeordneten bogenverarbeitenden Maschine, initiiert mittels eines beispielsweise einer Anlegtrommel 21 zugeordneten Inkrementalgebers 25, taktgebenden angesteuert werden.
    In der Steuereinheit 24 sind weiterhin ein Kennlinien- und ein Arbeitsdiagrammspeicher vorgesehen. Im Arbeitsdiagrammspeicher sind die Arbeitsdiagramme der Arbeits- und Steuerorgane in Abhängigkeit von der Winkelstellung und/oder von der Arbeitsgeschwindigkeit der bogenverarbeitenden Maschine abgelegt, während ein Kennlinienspeicher Kennlinien, die den einzelnen zur Verarbeitung gelangenden bogenförmigen Materialien zugeordnet sind, abgespeichert sein können. Damit können die einzelnen Antriebe 22, 26 bzw. Teilantriebe 23.1, 23.2 synchronisiert angesteuert und in Abhängigkeit von der Arbeitsgeschwindigkeit oder von dem jeweilig zur Verarbeitung gelangenden bogenförmigen Materialien zueinander phasenverschoben werden. Es ist auch möglich, die Arbeitsdiagramme der Arbeitsorgane bzw. Steuerorgane in Abhängigkeit von der Arbeitsgeschwindigkeit und/oder dem zum Einsatz gelangenden Verarbeitungsgut zu variieren und damit z.B. den jeweiligen Bedingungen optimal angepaßte Bahnkurven der Arbeitsorgane zu realisieren. Durch die Erzeugung der ungleichmäßigen Bewegungen der Arbeitsorgane 7, 8 unmittelbar mittels der Antriebe 22, 26 bzw. Teilantriebe 23.1, 23.2 können die Übertragungsglieder als einfache Mechanismen, in der Regel Hebelmechanismen mit einer geringen Anzahl von Gliedern, ausgebildet werden.     FIG. 1 shows a sheet feeder 1 with a belt table 2, a feed table 3 and front marks 4 and side marks 5 assigned to it. The belt table 2 has a table plate 17 and belt rollers 12, 13 extending transversely to a sheet conveying direction 11. The belt rollers 12, 13 are wrapped by at least two conveyor belts 14, which are guided by deflection rollers 15 and tensioning rollers 16. The conveyor belts 14 are driven, for example, by means of the belt roller 12 or 13 in the direction of rotation 18. Corresponding to the belt roller 12 facing the sheet feeder 1 is a clock roller 19 which is controlled against the belt roller 12 in the machine cycle.
    The feed table 3 is followed by a vibrating system 20 and this is followed by the feed drum 21 of a printing unit, not shown.
    A sheet separator 6 with separating suction devices 7 and transport suction devices 8 is provided in the sheet feeder 1. A sheet stack 10 consisting of sheets 9 is also arranged in sheet feeder 1. The sheet separator 6 is designed as a functional unit and can, in addition to the working elements separating and transport suction devices 6, 7 shown in the exemplary embodiment, further working elements such as, for example, a push-button foot or control elements for supplying a blowing and / or supporting the sheet 9, or suction air flow included. In this case, in addition to the work and control elements, the associated transfer elements which are necessary for the realization of the work task and which produce irregular movements are arranged in the sheet separator 6. Separate drives 22, 23, 26 are also provided on the sheet separator 6, at least one separate drive 22, 23, 26 being provided for each working member or control member. In the exemplary embodiment, the separating suction devices 7 are assigned the drive 22, the transport suction devices 8 the drive 23 and a control device 27 the drive 26. The drives 22, 23, 26 can consist of separately controllable partial drives, which is illustrated in the drive 23 of the transport suction device 7 by the provision of, for example, two partial drives 23.1 and 23.2. By providing several partial drives, it is possible, for example, to guide the respective working element on a trajectory with several degrees of freedom.
    The drives 22, 23.1, 23.2, 26 can be designed as linear drives or servomotors, in particular three-phase servomotors being provided. The drives 22, 23 are designed as three-phase servomotors 28, 29 and the partial drive 23.1 as three-phase servo motor 30 and the partial drive 23.2, for example, as a linear motor 31. The drives 22, 26 and the partial drives 23.1, 23.2 are connected to a control unit 24 which, using clock signals from the downstream sheet-processing machine, initiated by means of an incremental encoder 25 assigned, for example, to a feed drum 21, is triggered in a clocking manner.
    In the control unit 24, a characteristic curve and a work diagram memory are also provided. The working diagrams of the working and control elements are stored in the working diagram memory as a function of the angular position and / or the working speed of the sheet-processing machine, while a characteristic curve memory, which is assigned to the individual sheet-shaped materials to be processed, can be stored. In this way, the individual drives 22, 26 or partial drives 23.1, 23.2 can be controlled synchronously and can be phase-shifted with respect to one another depending on the working speed or on the arc-shaped materials that are being processed. It is also possible to vary the work diagrams of the work organs or control organs as a function of the working speed and / or the material to be processed and thus, for example, to implement path curves of the work organs which are optimally adapted to the respective conditions. By generating the uneven movements of the working elements 7, 8 directly by means of the drives 22, 26 or partial drives 23.1, 23.2, the transmission links can be designed as simple mechanisms, generally lever mechanisms with a small number of links.
