Description

Die Erfindung betrifft einen Bogenanleger der im Gattungsbegriff des Anspruchs 1 angegebenen Art. Ein derartiger Bogenausleger ist aus der DE-A 2 750 105 bekannt.The invention relates to a sheet feeder of the type specified in the preamble of claim 1. Such a sheet delivery is known from DE-A 2 750 105.

Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, einen Bogenanleger gattungsgemäßer Art zu verbessern, daß auch die dem Stapeltisch zugeordneten Andrückrollen automatisch in Abhängigkeit vom jeweils verarbeiteten Bogenformat einstellbar sind und daß dennoch eine einfache und kostengünstige Bauweise erreicht wird.Proceeding from this, it is an object of the present invention to improve a sheet feeder of the generic type that the pressure rollers assigned to the stacking table can also be set automatically as a function of the sheet format processed in each case and that a simple and inexpensive construction is nevertheless achieved.

Diese Aufgabe wird durch die kennzeichnenden Maßnahmen des Anspruchs 1 gelöst.This object is achieved by the characterizing measures of claim 1.

Die Verwendung einer abgestufte Steigungen aufweisenden Gewindespindel zur Verstellung der hintereinander angeordneten Andrückrollenreihen stellt in vorteilhafter Weise sicher, daß lediglich eine Spindel benötigt wird und dennoch die hinteren Andrückrollen um ein geringeres Maß verstellt werden können als die vorderen Andrückrollen. Obwohl in vorteilhafter Weise für sämtliche Andrückrollen lediglich eine Stellspindel benötigt wird, kann hier die vordere Andrückrollenreihe bei jedem Format 30 eingestellt werden, daß die über den Tisch hinweggehenden Bogen beim Erreichen der Vordermarken außer Eingriff mit den Andrückrollen sind, wodurch ein Stauchen der Bogen vermieden wird. Gleichzeitig können dabei die hinteren Andrückrollen lediglich so weit verstellt werden, daß ein zuverlässiger Transport der Bogen bis zur Anlage an den Vordermarken gewährleistet ist.The use of a stepped lead screw for adjusting the rows of pressure rollers arranged in an advantageous manner ensures that only one spindle is required and the rear pressure rollers can nevertheless be adjusted to a lesser extent than the front pressure rollers. Although advantageously only one adjusting spindle is required for all the pressure rollers, the front pressure roller row can be set for each format 30 so that the sheets passing over the table are disengaged from the pressure rollers when the front marks are reached, thereby avoiding compression of the sheets . At the same time, the rear pressure rollers can only be adjusted so far that a reliable transport of the sheets to the front marks is guaranteed.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen gekennzeichnetAdvantageous further developments are characterized in the subclaims

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

In der Zeichnung zeigen:

  • Fig. 1 eine Seitenansicht eines erfindungsgemäßen Bogenanlegers,
  • Fig. 2 eine Teildraufsicht auf den hinteren, dem Stapel zugeordneten Bereich des erfindungsgemäßen Bogenanlegers und
  • Fig. 3 eine Teildraufsicht auf den vorderen Bereich des erfindungsgemäßen Bogenanlegers mit den im Bereich des Fördertisches angeordneten Seitenziehmarken.
The drawing shows:
  • 1 is a side view of a sheet feeder according to the invention,
  • Fig. 2 is a partial plan view of the rear, the stack associated area of the sheet feeder and
  • Fig. 3 is a partial plan view of the front region of the sheet feeder according to the invention with the side pull marks arranged in the region of the conveyor table.

Der grundsätzliche Aufbau und die Funktionsweise eines Bogenanlegers sind an sich bekannt und bedürfen daher im vorliegenden Zusammenhang keiner weiteren Erläuterung mehr. In der schematischen Darstellung der Figuren 1 bis 3 wurde das Anlegergestell aus Gründen der Übersichtlichkeit weggelassen.The basic structure and mode of operation of a sheet feeder are known per se and therefore require no further explanation in the present context. In the schematic illustration of FIGS. 1 to 3, the feeder rack has been omitted for reasons of clarity.

Die Figur 1 zeigt dementsprechend einen Stapel 1, der auf einem Stapeltisch 2 aufgenommen ist. Der Stapeltisch 2 ist an Hubketten 3 aufgehängt, die über mittels eines Motors 4 schrittweise antreibbare Kettenräder 5 geführt sind. Die Höhe des Stapels wird in Abhängigkeit von der Höhe der an stationären Vorderanschlägen 6 anliegenden Stapelvorderkante eingestellt. Hierzu ist ein die Oberseite der Stapelvorderkante etwa im Bereich der Anlegermittellängsebene taktweise abtastender, mechanischer Taster 7 vorgesehen, der über ein Gestänge mit zwei einander gegenüberliegenden, eine Zweipunktregelung bildenden Schaltern 8 zusammenwirkt, über die der Motor 4 aktivierbar bzw. passivierbar ist. Der taktweise Stapeleingriff des Tasters 7 wird durch zwei eine Hubbewegung bzw. eine Schwenkbewegung bewerkstelligende, im Takt des Bogenanlegers angetriebene Kurvenscheiben 9 bewerkstelligt. Der Taster 7 ist dementsprechend an einem Kipphebel 10 befestigt, der auf einem Hubgestänge 11 schwenkbar gelagert ist, dessen unteres Ende mit den Schaltern 8 zusammenwirkt.Accordingly, FIG. 1 shows a stack 1 which is received on a stacking table 2. The stacking table 2 is suspended on lifting chains 3, which are guided by chain wheels 5 which can be driven step by step by means of a motor 4. The height of the stack is set as a function of the height of the front edge of the stack resting against stationary front stops 6. For this purpose, a mechanical button 7 is provided, which intermittently scans the top of the front edge of the stack, for example in the area of the feeder center plane, which interacts via a linkage with two opposing switches 8, which form a two-point control and via which the motor 4 can be activated or passivated. The intermittent stacking engagement of the button 7 is accomplished by two cam disks 9, which produce a lifting movement or a pivoting movement and are driven in time with the sheet feeder. The button 7 is accordingly attached to a rocker arm 10 which is pivotally mounted on a lifting rod 11, the lower end of which cooperates with the switches 8.

Oberhalb des Stapels 1 ist ein Saugkopf 12 angeordnet, der mit Hubsaugern 13 zum Anheben des jeweils obersten Bogens und Schleppsaugern 14 zum Vorwärtstransport des jeweils angehobenen Bogens sowie mit einem bei jedem Takt neu auf die Bogenhinterkante aufsetzenden Drückerfuß 15 versehen ist. Der Saugkopf 12 ist auf einer parallel zur Bogentransportrichtung verlaufenden, durch eine am Anlegergestell befestigte Vierkantschiene gebildeten, horizontal ausgerichteten Längsführung 16 verschiebbar geführt und kann daher bei jedem Formatwechsel so eingestellt werden, daß sein Drückerfuß 15 genau die Stapelhinterkante abtastet. Zur Verstellung des Saugkopfes 12 dient eine mittels eines Stellmotors 17 antreibbare Gewindespindel 18, die an der Längsführung 16 in axialer Richtung abgestützt ist und in eine über die Längsführung 16 seitlich auskragende Gewindemuffe 19 des Saugkopfes eingreift. In der eingestellten Betriebsstellung wird der Saugkopf 12 durch eine in Figur 2 angedeutete Spanneinrichtung 20 an der Längsführung 16 festgeklemmt. Die Spanneinrichtung 20 kann einfach als pneumatisch betätigbares Zylinder-Kolbenaggregat ausgebildet sein.Above the stack 1, a suction head 12 is arranged, which is provided with lifting suction devices 13 for lifting the top sheet in each case and drag suction devices 14 for the forward transport of the respectively lifted sheet, as well as with a presser foot 15 placed on the trailing edge of the sheet at every cycle. The suction head 12 is displaceably guided on a horizontally oriented longitudinal guide 16 which runs parallel to the sheet transport direction and is formed by a square rail fastened to the feeder frame and can therefore be adjusted with each format change so that its presser foot 15 precisely scans the trailing edge of the stack. A threaded spindle 18, which can be driven by means of an actuator 17, is used to adjust the suction head 12, which is supported on the longitudinal guide 16 in the axial direction and engages in a threaded sleeve 19 of the suction head which projects laterally over the longitudinal guide 16. In the set operating position, the suction head 12 is clamped to the longitudinal guide 16 by a tensioning device 20 indicated in FIG. The clamping device 20 can simply be designed as a pneumatically actuated cylinder-piston unit.

Die Arbeitshöhe des Saugkopfes 12 ist entsprechend der Höhe der Stapelhinterkante einstellbar, die von der Höhe der Stapelvorderkante abweichen kann. Hierzu ist die dem Saugkopf 12 zugeordnete Längsführung 16 samt zugeordneter Gewindespindel 18 mit Stellmotor 17 auf lotrecht zur Bogentransportebene auf dem Anlegergestell aufgenommenen Gewindespindeln 21 aufgenommen, die über ein jeweils zugeordnetes Kegelradvorgelege 22 antreibbar sind. Die beiden Kegelradvorgelege 22 sind über eine längsführungsparallele Welle 23 miteinander verbunden, die über einen zugeordneten Stellmotor 24 antreibbar ist. Die Steuerung des Stellmotors 24 erfolgt über den als Taster wirkenden Drückerfuß 15, der an zwei parallelen Schwingen 25. aufgenommen ist, von denen eine mit zwei einander gegenüberliegenden, eine Zweipunktsteuerung bildenden Schaltern 26 zusammenwirkt, mittels derer der Stellmotor 24 aktivierbar bzw. passivierbar ist.The working height of the suction head 12 can be adjusted according to the height of the rear edge of the stack, which can differ from the height of the front edge of the stack. For this purpose, the longitudinal guide 16 assigned to the suction head 12 together with the associated threaded spindle 18 with the servomotor 17 is accommodated on threaded spindles 21 which are accommodated perpendicular to the sheet transport plane on the feeder frame and which can be driven via a respectively assigned bevel gear countershaft 22. The two bevel gear countershaft 22 are connected to one another via a shaft 23 which is parallel to the longitudinal guide and which can be driven via an associated servomotor 24. The control of the servomotor 24 takes place via the presser foot 15 acting as a button, which is received on two parallel rockers 25, one of which interacts with two opposing switches 26 which form a two-point control and by means of which the servomotor 24 can be activated or passivated.

Der Stapel 1 liegt mit seiner Vorderkante an den stationären, durch am Anlegergestell befestigte Leisten gebildeten Vorderanschlägen 6 an. Die Seitenkanten des Stapels 1 befinden sich zwischen praktisch eine Papierführung bildenden Seitenanschlägen 27. Daneben können sich sogenannte Seitenbläser 28 befinden, die an eine Blasluftquelle angeschlossen sind. Die Lage der Stapelseitenkanten ändert sich mit dem Format, wie aus Figur 2 durch Vergleich der durchgezogenen und gestrichelten Grundrißkanten des Stapels 1 bzw. 1a erkennbar ist. Die Seitenanschläge 27 und Seitenbläser 28 sind daher ebenso wie der Saugkopf 12 auf das jeweilige Bogenformat einstellbar. Hierzu ist, wie am besten aus Figur 2 erkennbar ist, eine quer zur Bogentransportrichtung verlaufende Längsführung 29 vorgesehen, auf der zwei die beidseitigen Seitenanschläge 27 und Seitenbläser 28 aufnehmende Halter 30 verschiebbar gelagert sind. Zur Verstellung der Halter 30 dient eine parallel zur zugeordneten Längsführung verlaufende Gewindespindel 31, die mit gegenläufigen Gewindeabschnitten mit jeweils einem Halter 30 im Eingriff ist und mittels eines Stellmotors 32 antreibbar ist. Zur Bewerkstelligung einer Feineinstellung der Seitenanschläge 27 und Seitenbläser 28 sind diese über eine manuell betätigbare Stellschraube 33 mit dem jeweils zugeordneten Halter 30 verbunden.The stack 1 lies with its front edge against the stationary front stops 6 formed by strips attached to the feeder frame. The side edges of the stack 1 are located between side stops 27 which practically form a paper guide. In addition, so-called side blowers 28 can be located which are connected to a blown air source. The location of the stack side can ten changes with the format, as can be seen from FIG. 2 by comparing the solid and dashed outline edges of the stack 1 or 1a. The side stops 27 and side blowers 28, like the suction head 12, can therefore be adjusted to the respective sheet format. For this purpose, as can best be seen from FIG. 2, a longitudinal guide 29 running transversely to the sheet transport direction is provided, on which two holders 30 receiving the side stops 27 and side blowers 28 on both sides are slidably mounted. A threaded spindle 31, which runs parallel to the associated longitudinal guide, is used to adjust the holder 30, which engages with opposite threaded sections, each with a holder 30, and can be driven by means of a servomotor 32. To achieve a fine adjustment of the side stops 27 and side blowers 28, these are connected to the respectively assigned holder 30 via a manually operable adjusting screw 33.

Die Gewindespindel 31 und die parallele Längsführung 29 sind durch seitliche Lagerschilde 34 zu einem Rahmengestell 35 zusammengefaßt. Die Lagerschilde 34 sind mit längsführungsparallel, also quer zur Transportrichtung verlaufenden Führungszapfen 36 verschiebbar im Anlegergestell gelagert, so daß der gesamte Rahmen 35, wie Figur 2 weiter erkennen läßt, von einer rechten in eine linke Endstellung gebracht werden kann und umgekehrt. Zur Verschiebung des Rahmens 35, der die Seitenanschläge 27 und Seitenbläser 28 samt zugeordneter Formateinstelleinrichtung enthält, ist ein fembedienbares Stellglied 37 vorgesehen, das im dargestellten Ausführungsbeispiel als pneumatisch betätigbares Zylinder-Kolbenaggregat ausgebildet ist. Die seitliche Verstellbarkeit des Rahmens 35 ermöglicht eine gegenüber der Anlegermittellängsebene nach links oder rechts so weit versetzte Positionierung des Stapels 1, daß die Bogen vor ihrer Übergabe an eine Verarbeitungsmaschine mittels im Bereich eines dem Stapelaufnahmebereich nachgeordneten Fördertisches 38 angeordneter Seitenziehmarken 39 genau auf Mitte gesetzt werden können.The threaded spindle 31 and the parallel longitudinal guide 29 are combined by side end plates 34 to form a frame 35. The end shields 34 are slidably mounted in the feeder frame with guide pins 36 which run parallel to the longitudinal guide, that is to say transversely to the transport direction, so that the entire frame 35, as can further be seen in FIG. 2, can be brought from a right-hand to a left-hand end position and vice versa. To move the frame 35, which contains the side stops 27 and side blowers 28 together with the associated format setting device, a remote control actuator 37 is provided, which in the exemplary embodiment shown is designed as a pneumatically actuated cylinder-piston unit. The lateral adjustability of the frame 35 enables the stack 1 to be positioned so far to the left or right with respect to the longitudinal plane of the feeder that the sheets can be placed exactly in the middle before being transferred to a processing machine by means of side drawing marks 39 arranged in the region of a conveyor table 38 arranged downstream of the stack receiving area .

Der von den Hubsaugern 13 jeweils angehobene und an die Schleppsauger 14 übergebene Bogen wird durch diese an vor den Vorderanschlägen 6 angeordnete Transportwalzen 40 übergeben und gelangt über diese auf den normalerweise nach vorne etwas geneigten Fördertisch 38. Dieser ist von über seine Breite verteilten Transportbändern 41 überzogen, denen Andrückrollen 42 zugeordnet sind. Am vorderen Ende des Fördertisches 38 sind schwenkbare Vordermarken 43 angeordnet, an denen die Bogenvorderkante ausgerichtet wird. Die Andrückrollen 42 müssen bei jedem Formatwechsel so eingestellt werden, daß der an den Vordermarken 43 anliegende Bogen gerade außer Eingriff mit der vordersten Andrückrollenreihe ist und daher nicht gestaucht wird. Die nebeneinander angeordneten Andrückrollen 42 sind hierzu auf einem durch eine über die ganze Maschinenbreite durchgehende Schiene gebildeten, gemeinsamen Träger 44 aufgenommen und mittels dieses gemeinsam verstellbar. Zur Verstellung dient eine mittels eines Stellmotors 45 antreibbare Gewindespindel 46, die am Anlegergestell axial abgestützt ist und im Eingriff mit dem Träger 44 bzw. den hintereinander angeordneten Andrückrollenreihen zugeordneten Trägern 44 ist, sofern auch die hinteren Andrückrollen, wie im dargestellten Ausführungsbeispiel, verstellt werden sollen. In dieseum Falle sind auch die hinteren Andrückrollenreihen auf jeweil einem gemeinsamen Träger 44 aufgenommen, der im Eingriff mit der Gewindespindel 46 ist, wie Figur 1 anschaulich erkennen läßt. Im dargestellten Ausführungsbeispiel beisitzt die Gewindespindel 46 den hintereinander angeordneten Trägern 44 zugeordnete Gewindeabschnitte mit abgestufter Steigung. Die Steigung des hinteren Gewindeabschnitts ist kleiner als die Steigung des vorderen Gewindeabschnitts, was im Bereich der hinteren Andrückrollen 42 zu einem kleineren Stellweg als im Bereich der vorderen Andrückrollen führt. Hierdurch wird erreicht, daß sich die hinteren Andrückrollen bei jeder Einstellung der vorderen Andrückrollen 42 etwa im Bereich zwischen den vorderen Andrückrollen und den Transportwalzen 40 befinden, was einen zuverlässigen Bogentransport ergibt.The sheet lifted by the lifting suction devices 13 and transferred to the drag suction devices 14 is passed through these to transport rollers 40 arranged in front of the front stops 6 and passes via these onto the conveyor table 38, which is normally slightly inclined forward. This is covered by transport belts 41 distributed over its width , which are assigned pressure rollers 42. At the front end of the conveying table 38, pivotable front marks 43 are arranged, on which the leading edge of the sheet is aligned. The pressure rollers 42 must be adjusted with each format change so that the sheet lying on the front marks 43 is just out of engagement with the front row of pressure rollers and is therefore not compressed. For this purpose, the pressure rollers 42 arranged next to one another are received on a common support 44 formed by a rail running across the entire width of the machine and are jointly adjustable by means of this. For adjustment, a threaded spindle 46, which can be driven by means of a servomotor 45, is axially supported on the feeder frame and is in engagement with the carrier 44 or the carriers 44 assigned to the rows of pressure roller rows, provided that the rear pressure rollers are also to be adjusted, as in the exemplary embodiment shown . In this case, the rear rows of pressure rollers are each received on a common carrier 44 which is in engagement with the threaded spindle 46, as can be clearly seen in FIG. In the exemplary embodiment shown, the threaded spindle 46 has threaded sections associated with the brackets 44 arranged one behind the other, with a stepped pitch. The slope of the rear threaded section is smaller than the slope of the front threaded section, which leads to a smaller adjustment path in the area of the rear pressure rollers 42 than in the area of the front pressure rollers. This ensures that the rear pressure rollers are approximately in the area between the front pressure rollers and the transport rollers 40 with each adjustment of the front pressure rollers 42, which results in a reliable sheet transport.

Stromaufwärts von den Vordermarken 43 sind im Bereich des Fördertisches 38 zwei bezüglich der Anlegermittellängsebene einander gegenüberliegende Seitenziehmarken 39 vorgesehen, von denen jeweils eine zur seitlichen Ausrichtung der Bogen aktiviert ist. Die Seitenziehmarken 39 kommen mit dem seitlichen Bogenrand in Eingriff und sind dementsprechend wie die Seitenanschläge 27 auf die Bogenformatbreite einstellbar. Hierzu sind die Seitenziehmarken 39, wie am besten aus Figur 3 erkennbar ist, auf einer durch eine über die Maschinenbreite durchgehende Schiene gebildeten, quer zur Bogentransportrichtung laufenden Längsführung 47 aufgenommen. Zur Verstellung der beiden Seitenmarken 39 ist jeder Seitenmarke 39 eine Gewindespindel 48 zugeordnet. Die beiden Gewindespindeln 48 sind in axialer Richtung fluchtend mit mittigem Abstand nebeneinander angeordnet. Dieser Abstand wird durch eine im Bereich zwischen den beiden Gewindespindeln 48 angeordnete Antriebseinheit 49 mit Stellmotor 50 überbrückt, die alternativ mit einer der beiden Gewindespindeln 48 kuppelbar ist. Im dargestellten Ausführungsbeispiel besitzt die Antriebseinheit einen verschiebbar auf der Längsführung 47 aufgenommenen Getriebekasten 51, an dem der Stellmotor 50 befestigt ist und in welchem ein mittels des Stellmotors 50 antreibbares, zwei Abtriebswellen aufweisendes Doppelkegelradgetriebe 52 angeordnet ist. Die in Bogentransportrichtung verlaufende angetriebene Welle des Doppelkegelradgetriebes 52 ist mit dem am Getriebekasten 51 befestigten Stellmotor 50 antriebsmäßig fest verbunden. Die beiden Abtriebswellen 53 des Doppelkegelradgetriebes 52 sind fluchtend zu den beiden Gewindespindeln 48 angeordnet und mit je einem Kupplungselement 54 versehen, das zum Eingriff mit einem gegenüberliegenden gewindespindelseitig befestigten Kupplungselement 55 bringbar ist. Zum Verschieben des Getriebekastens 51 ist ein fernbedienbares Stellglied 56 vorgesehen, das einfach als pneumatisch betätigbares Zylinder-Kolbenaggregat ausgebildet sien kann. Anstelle einer Verschiebung der Antriebseinrichtung könnte auch einfach nur eine elektrische oder pneumatische Aktivierung der linken bzw. rechten Wellenkupplung vorgesehen sein.Upstream of the front marks 43, two side pull marks 39 are provided in the region of the conveyor table 38 with respect to the longitudinal axis of the feeder center, one of which is activated for the lateral alignment of the sheets. The side pulling marks 39 come into engagement with the lateral sheet edge and, like the side stops 27, can accordingly be adjusted to the sheet format width. For this purpose, as can best be seen from FIG. 3, the side drawing marks 39 are received on a longitudinal guide 47 formed by a rail that runs across the machine width and runs transversely to the sheet transport direction. To adjust the two side marks 39, a threaded spindle 48 is assigned to each side mark 39. The two threaded spindles 48 are arranged in alignment in the axial direction with a central spacing next to one another. This distance is bridged by a drive unit 49 arranged in the area between the two threaded spindles 48 with a servomotor 50, which can alternatively be coupled to one of the two threaded spindles 48. In the exemplary embodiment shown, the drive unit has a gear box 51 which is displaceably received on the longitudinal guide 47 and to which the servomotor 50 is fastened and in which a double bevel gear 52 which can be driven by means of the servomotor 50 and has two output shafts is arranged. The driven shaft of the double bevel gear 52 running in the sheet transport direction is fixedly connected to the actuator 50 attached to the gear box 51. The two output shafts 53 of the double bevel gear 52 are aligned with the two threaded spindles 48 and each provided with a coupling element 54 which can be brought into engagement with an opposite coupling element 55 fastened on the threaded spindle side. To move the gearbox 51, a remote-controlled actuator 56 is provided, which is simply a pneumatically actuated cylinder piston benaggregat trained you can. Instead of shifting the drive device, it would also be possible to provide only an electrical or pneumatic activation of the left or right shaft coupling.

Die Seitenziehmarken 39 befinden sich in einem vor den vorderen Umlenkrollen der Transportbänder 41 liegenden Kanal 57 des Fördertisches 38. Zur Gewährleistung einer sauberen Bogenabstützung im Bereich des Kanals 57 ist dieser mittels balgartig abdeckbarer Abdeckungen 58 abdeckbar, die einerseits an der nach innen weisenden Kante des Gehäuses einer Seitenziehmarke 39 und andererseits an der nach außen weisenden Kante eines mittig angeordneten, den verschiebbaren Getriebekasten 51 übergreifenden Abdeckblechs 59 befestigt sind.The side pulling marks 39 are located in a channel 57 of the conveyor table 38 lying in front of the front deflection rollers of the conveyor belts 41. To ensure a clean arch support in the area of the channel 57, the latter can be covered by means of covers 58 that can be covered with bellows, which cover on the one hand on the inwardly facing edge of the housing a side pull mark 39 and, on the other hand, are fastened to the outwardly facing edge of a centrally arranged cover plate 59 which overlaps the displaceable gearbox 51.

Die in Abhängigkeit von der Höhe der Stapelvorderkante bzw. Stapelhinterkante aktivierbaren Stellmotoren 4 bzw. 24 sind, wie weiter oben bereits erwähnt, mittels der zugeordneten Schalter 8 bzw. 26 aktivierbar bzw. passivierbar. Die zur Formateinstellung vorgesehenen Stellmotoren, hier die Stellmotoren 17, 32, 45, 50 sind, wie in Figur 1 ferner angedeutet ist, mittels eines Rechners 60 ansteuerbar, in den das jeweilige Bogenformat in Form eines Längen- und Breitenmaßes eingegeben werden kann. Der Rechner 60 ist mit einer Tastatur 61 zum Vorwählen des Formats sowie einer Digitalanzeige 62 zum Anzeigen der eingegebenen Formatlänge und Formatbreite versehen und durch Signalleitungen 63 mit den anzusteuernden Stellmotoren 17, 32, 45 und 50 verbunden. Länge und Breite des Formatbogens werden auf je einer Tastatur eingegeben.The actuators 4 and 24 which can be activated as a function of the height of the front or rear edge of the stack can, as already mentioned above, be activated or passivated by means of the associated switches 8 and 26. The servomotors provided for setting the format, here the servomotors 17, 32, 45, 50 can, as is also indicated in FIG. 1, be controlled by means of a computer 60, into which the respective sheet format can be entered in the form of a length and width dimension. The computer 60 is provided with a keyboard 61 for preselecting the format and a digital display 62 for displaying the entered format length and format width, and is connected to the servomotors 17, 32, 45 and 50 to be controlled by signal lines 63. The length and width of the format sheet are entered on a keyboard.

Durch Drücken eines Startknopfes fahren dann die mit Stellmotoren versehenen Aggregate, wie Saugkopf und Seitenanschläge etc. auf das eingegebene Formatmaß. Häufig benötigte, bestimmte Formatabmessungen können im Rechner gespeichert werden und sind dann über eine Code-Nr. jederzeit abrufbar. Hierbei fahren dann die einzelnen Aggregate, wie Saugkopf und Seitenanschläge etc. die im Speicher festgelegten Positionen an. Eine andere Möglichkeit zur Eingabe besteht darin, daß in einem an der Digitalanzeige 62 angezeigten Suchlauf alle Formate durchlaufen werden und zur Eingabe des gewünschten Formats der Suchlauf einfach bei dem gewünschten Wert gestoppt wird. Die Ansteuerung der einzelnen Stellmotoren kann gleichförmig erfolgen. Hier soll die Ansteuerung so erfolgen, daß die gewünschte Position zunächst in einem Schnellgang angefahren und dann in einem Langsamgang genau eingestellt wird. Die Stellmotoren sind dementsprechend als Mehrgeschwindigkeitsmotoren ausgebildet. Vom Stellwert für den Saugkopf 12 (Formatlänge) kann der für die Andrückrollen 42 und vom Stellwert für die Seitenanschläge 27 (Formatbreite) kann der für die Seitenmarke 39 abgeleitet werden, was die Steuerung vereinfacht.By pressing a start button, the units provided with servomotors, such as the suction head and side stops, etc., move to the entered format. Often required, certain format dimensions can be saved in the computer and are then assigned a code no. available at any time. The individual units such as the suction head and side stops etc. then move to the positions defined in the memory. Another possibility for input is that all the formats are run through in a search run displayed on the digital display 62 and the search run is simply stopped at the desired value in order to enter the desired format. The individual servomotors can be controlled uniformly. Here the control should take place in such a way that the desired position is first approached in an overdrive and then set precisely in a slow gear. The servomotors are accordingly designed as multi-speed motors. From the control value for the suction head 12 (format length) that for the pressure rollers 42 and from the control value for the side stops 27 (format width) that for the side mark 39 can be derived, which simplifies the control.

In Figur 2 ist mit durchgezogenen Linien die Positionierung der einzelnen Aggregate bei einem vergleichsweise großen Bogenformat und mit gestrichelten Linien bei einem verhältnismäßig kleinen Bogenformat angedeutet. Die Umstellung erfolgt einfach dadurch, daß in den Rechner 60 das neue Format eingegeben wird, indem der Suchlauf beim gewünschten Längenmaß bzw. Breitenmaß gestoppt wird. Das eingestellte Maß wird durch die Digitalanzeige 62 angezeigt, hier 720 Längenmaß und 1040 Breitenmaß. Nach Eingabe der gewünschten Maße wird die Ansteuerung der Stellmotoren freigegeben. Die Tastatur 61 benötigt dementsprechend lediglich Vorwahltasten für Länge bzw. Breite sowie zum Aktivieren und Stoppen des Suchlaufs und zum Freigeben der zu den Stellmotoren führenden Signalleitungen 63. Daneben ist selbstverständlich ein Hauptschalter zum Ein- und Ausschalten vorgesehen. Die Stellglieder 37 bzw. 56 zum Verschieben des Rahmens 35 bzw. des Getriebekastens 51 können ebenfalls mittels des Rechners 60 angesteuert werden. In diesem Falle ist die Tastatur 61 mit entsprechenden Eingabemöglichkeiten versehen. Dasselbe gilt für Spanneinrichtungen zum Feststellen der einzelnen Aggregate, sofern derartige Spanneinrichtungen vorgesehen sind. Im dargestellten Ausführungsbeispiel sind lediglich dem angetriebene Teile enthaltenden Saugkopf 12 und den Seitenziehmarken 39 Spannvorrichtungen 20 zugeordnet, mittels derer die betreffenden Aggregate an der zugeordneten Längsführung festklemmbar sind.In Figure 2, the positioning of the individual units is indicated with solid lines in a comparatively large sheet format and with dashed lines in a relatively small sheet format. The changeover is made simply by entering the new format into the computer 60 by stopping the search at the desired length or width dimension. The set dimension is indicated by the digital display 62, here 720 length dimension and 1040 width dimension. After entering the desired dimensions, the control of the servomotors is released. Accordingly, the keyboard 61 only requires preselection keys for length or width as well as for activating and stopping the search run and for releasing the signal lines 63 leading to the servomotors. In addition, a main switch for switching on and off is of course provided. The actuators 37 and 56 for moving the frame 35 and the gearbox 51 can also be controlled by means of the computer 60. In this case, the keyboard 61 is provided with corresponding input options. The same applies to clamping devices for fixing the individual units, provided such clamping devices are provided. In the exemplary embodiment shown, only the suction head 12 containing driven parts and the side pulling marks 39 are assigned clamping devices 20, by means of which the relevant units can be clamped to the associated longitudinal guide.
