Description

Die Erfindung betrifft ein Verfahren zum wahlweisen Zuführen von Bogen oder Vorlaufbogen zu einer bogenverarbeitenden Maschine mit einem Bogenanleger, der einen Bogentrenner zum Vereinzeln der Bogen oder Vorlaufbogen von einem Stapel und unterstützt durch Taktrollen zum Transportieren der vereinzelten Bogen oder Vorlaufbogen in eine Transportrichtung zu einem Saugbändertisch aufweist, von dem die Bogen oder Vorlaufbogen zu einem Anlegtisch und von diesem zur bogenverarbeitenden Maschine transportiert werden, wobei eine das Höhenniveau des Stapels erfassende Abtasteinrichtung vorgesehen ist und der Antrieb des Bogenanlegers durch Einzelantriebe erfolgt, die mittels einer Verarbeitungselektronik, welche mit einer Steuereinrichtung der nachgeordneten Maschine verknüpft ist, gesteuert werden.
Bei derartigen bogenverarbeitenden Maschinen, insbesondere bei Bogendruckmaschinen ist es üblich, beim Verarbeiten von Vorlaufbogen diese abzuzählen und von Hand auf den im Bogenanleger befindlichen Stapel aufzulegen. Dazu ist es erforderlich, den Bogentrenner von der Oberseite des Stapels abzuheben und/oder den Stapel abzusenken. Nach dem Aufbringen und Ausrichten der Vorlaufbogen auf dem Stapel wird dieser mit seiner Oberseite einem Arbeitsniveau angepasst und der Bogentrenner der Oberseite des Stapels wieder angenähert. Danach können die Vorlaufbogen vom Stapel vereinzelt und der bogenverarbeitenden Maschine zugeführt werden.
Diese Verfahrensweise ist umständlich und aufwändig.
The invention relates to a method for selectively feeding sheet or leader sheet to a sheet processing machine with a sheet feeder having a sheet separator for separating the sheet or leader sheet from a stack and supported by clock rollers for transporting the separated sheet or leader sheet in a transport direction to a suction belt table from which the sheets or transfer sheets are transported to a feed table and from there to the sheet processing machine, wherein a height level of the stack detecting scanning is provided and the drive of the sheet feeder by individual drives, by means of processing electronics, which with a control device of the downstream machine is linked, controlled.
In such sheet-processing machines, in particular in sheet-fed printing machines, it is customary to count these out during the processing of the supply sheet and place them by hand on the stack located in the sheet feeder. For this purpose, it is necessary to lift the sheet separator from the top of the stack and / or lower the stack. After applying and aligning the flow sheet on the stack of this is adjusted with its top a working level and the sheet separator to the top of the stack approximated again. Thereafter, the flow sheets can be separated from the stack and fed to the sheet-processing machine.
This procedure is cumbersome and time-consuming.

Aus der DE 34 01 724 C2 ist es, um Vorlaufbogen verarbeiten zu können, bekannt, auf einem ersten Bogenanleger mit einem Bändertisch einen zweiten, modifizierten Bogenanleger mit einem Bändertisch anzuordnen und in diesem zweiten Bogenanleger die Vorlaufbogen zu stapeln. Die Enden der beiden Fördertische sind im Übergabebereich zur bogenverarbeitenden Maschine in einem geringen Abstand zueinander angeordnet. Zwischen den Bogenanlegern ist eine Antriebsverbindung herstellbar und durch eine Betriebsablaufschaltung können wahlweise Bogen oder Vorlaufbogen abgefördert und der bogenverarbeitenden Maschine zugeführt werden. Der Betriebsablaufschaltung ist eine Vorwahleinrichtung zugeordnet, mit der die Anzahl der abzufördernden Vorwahlbogen eingestellt werden kann.
Diese Vorrichtung bedingt einen hohen gerätetechnischen Aufwand.

Im dem Bogenanleger 1 zugewandten Bereich des Vortaufbogenbehälters 37 sind Vorderkantenanschläge,40 vorgesehen, die in einem Abstand zur Grundplatte 39 angeordnet sind, so dass auf der Grundplatte 39 aufliegende Vorlaufbogen 38 aus dem Vorlaufbogenbehälter, 37 geführt werden können, wobei zusätzlich eine Bogenleiteinrichtung 47 vorgesehen sein kann, die eine Verbindung zwischen Grundplatte 39 und Saugbändertisch 2 realisiert. Den Vorderkantenanschlägen 40 sind federnde Abstreifzungen 41 zugeordnet, die höhenverstellbar ausgeführt sind. Seitlich ist der Vorlaufbogenbehälter 32 mit Seitenanschlägen 42 und auf der dem Bogenanleger 1 abgewandten Seite mit Hiriterkantenanschlägen 43 versehen. Die Seiten- und die Hinterkantenanschläge 42, 43 sind verschiebbar der Grundplatte 39 zugeordnet, so dass diese auf das jeweils zur Verarbeitung gelangende Format eingestellt werden können. Die Seitenanschläge 42, die Hinterkantenanschläge 43 und die Vorderkantenanschläge 40 sind auf der zu den Vorlaufbogen 38 gerichteten Seite im unteren Abschnitt mit Blasdüsen versehen zum Vorlockern der im Vorlaufbogenbehälter 37 befindlichen Vorlaufbogen 38. Im Bereich der Vorderkantenanschläge 40 ist in der Grundplatte 39 eine Aussparung vorgesehen, in der eine Saugwalze 44 gelagert ist. Die Saugwalze 44 kann durch einen vierten Einzelantrieb 45 über einen Freilauf 46 angetrieben werden. Der vierte Einzelantrieb 45 wird von der Verarbeitungselektronik 33 des Bogenanlegers 1 angesteuert.
Bei einem taktsynchronen Nachführen des Bogenanlegers 1 wird von den Trennsaugern 13, angetrieben durch den dem Bogentrenner 12 zugeordneten ersten Einzelantrieb 19, der jeweils oberste Bogen 8 vom Stapel 9 vereinzelt und an die Transportsauger 14 übergeben, welche die vereinzelten Bogen 8 in Transportrichtung 17 fördern. Das Vereinzeln der Bogen 8 wird dadurch unterstützt, dass durch Bläser 36 der Stapel 9 aufgelockert und durch weitere Bläser 36 der jeweils von den Transportsaugern 14 geförderte Bogen 8 unterblasen wird. Die von den Transportsaugern 14 geförderten Bogen 8 werden von den taktmäßig aufsetzenden Taktrollen 29 gegen die Antriebswalze 23 geführt und danach von den Transportsaugern 14 freigegeben. Dabei wird die Klappenwelle 21, angetrieben durch den dritten Einzelantrieb 31, aus der Bahn der Bogen 8 geschwenkt und die Blasluftzufuhr zur Blasstange 22 ist unterbrochen. Die von den Taktrollen 29 gegen die Antriebswalze 23 geführten Bogen 8 werden von den Saugbändern 26, die über den Saugkasten 26 ständig mit Unterdruck beaufschlagt werden, erfasst und unterlappt auf den Anlegtisch 3 sowie mit der Vorderkante gegen die in Arbeitsposition befindlichen Vordermarken 4 transportiert, wobei die Bogen 8 durch die Kontrolleinrichtung 32 detektiert werden.
Soll eine Anzahl von Vorlaufbogen 38 in die bogenverarbeitende Maschine gefördert werden, wird die Bogenzufuhr vom Bogenanleger 1 unterbrochen, die Verknüpfung zwischen Maschinensteuerung 34 und Verarbeitungselektronik 33 gelöst sowie der Bogenanleger 1 stillgesetzt, wobei auch die Saug- und Blasluftzufuhr zum Bogentrenner 12 und die Btastuftzufuhr zu den Bläsern 36 unterbrochen; während der Saugkasten 25 weiter mit Unterdruck beaufschlagt wird. Nachfolgend wird über eine in der Verarbeitungselektronik 33 integrierte Vorwahleinrichtung die Anzahl der der bogenverarbeitenden Maschine zuzuführenden Vorlaufbogen 38 und ein Startbefehl in die Verarbeitungselektronik 33 eingegeben. Dadurch wird mittels der Verarbeitungselektronik 33 der Stellantrieb 16 aktiviert und durch diesen der Bogentrenner 12 von der Oberfläche des Stapels 9 abgehoben: Ebenfalls werden der zweite Einzelantrieb 28 und der dritte Einzelantrieb 31 aktiviert, wobei die Drehrichtung des zweiten Einzelantriebs 28 und damit die Drehrichtung der die Saugbänder 26 führenden Antriebswalze 23 umgekehrt wird. Außerdem wird der vierte Einzelantrieb 45 aktiviert und die dem Vorläufbogenbehälter 37 zugeordneten Blasdüsen, Kugelventildüsen mit Blasluft und die Saugwalze 44 mit Saugluft beaufschlagt. Weiterhin wird der Blasstange 22 Blasluft zugeführt. Da die Taktrollen 29 antriebsseitig mit der Antriebswalze 23 verbunden sind, werden diese getaktet gegen die Antriebswalze 23 gesteuert. Prinzipiell ist es auch möglich, den Taktrollen 29 einen separaten Antrieb zuzuordnen und diesen durch die Verarbeitungselektronik 33 anzusteuern.
Damit kann von der Saugwalze 44 der jeweils unterste Vortauf bogen 38 erfasst und durch den zwischen Grundplatte 39 sowie Vorderkantenanschlägen 40 gebildeten Spalt abgeführt werden, wobei die Abstreifzungen 41 Doppelbogenentnahmen verhindern. Der jeweils von der Saugwalze 44 vereinzelte Vorlaufbogen 38 wird von der Bogenleiteinrichtung 47 geführt auf den Saugbändertisch 2 gefördert und von den Saugbändern 26 erfasst. Durch die Saugwalze 44 wird eine Transportgeschwindigkeit realisiert, die gleich oder geringfügig niedriger ist als die Transportgeschwindigkeit der Saugbänder 26, so dass die Vorlaufbogen 38 von den Saugbändern 26 aus dem Vorlaufbogenbehälter 37 gezogen werden können, wobei der Freilauf 46 anspricht. Der von den Saugbändern 26 erfasste Vorlaufbogen 38 wird entgegen der Transportrichtung 17 auf den Stapel 9 transportiert. Dabei wird der Transport unterstützt durch die Taktrollen 29, die taktweise abgesenkt werden, und durch die Klappenwelle 21, die mittels ihrer Schwenkbewegung den jeweiligen Vorlaufbogen 38 auf den Stapel 9 schiebt.
Der Transport der Vorlaufbogen 38 zum Stapel 9 wird unterstützt durch den von der Blasstange 22 ausgehenden, etwa entgegen der Transportrichtung 17 gerichtet verlaufenden Blasluftstrom. Auf dem Stapel 9 werden die Vorlaufbogen 38 durch die Hinterkantenanschläge 15 sowie durch die Seitenbleche 20 oder Führungselemente 20.1 zentriert.
Hat ein Vorlaufbogen 38 die Saugwalze 44 verlassen, wird der nunmehr unterste Vorlaufbogen 38 im Vorlaufbogenbehälter 37 abgeführt, bis die vorgegebene Anzahl von Vorlaufbogen 38 erreicht ist. Danach wird der vierte Einzelantrieb 45 stillgesetzt, während die Saugbänder 26 den letzten Vorlaufbogen 38 auf den Stapel 9 fördern. Ebenfalls kann die Saugluft zur Saugwalze 44 und die Blasluftzufuhr zu den Düsen des Vorlaufbogenbehälters 37 unterbrochen werden. Durch die auf den Stapel 9 geförderten Vorlaufbogen 38 wird das Höhenniveau des Stapels 9 verändert. Diese Veränderung wird von der Abtasteinrichtung 18 erfasst und der Stapel 9 mittels des nicht dargestellten Aufzugs abgesenkt und so ein entsprechendes Arbeitsniveau eingehalten.
Nachdem der letzte Vorlaufbogen 38 auf dem Stapel 9 abgelegt wurde, werden der zweite Einzelantrieb 28, damit die Saugbänder 26 und die Taktrollen 29, und der dritte Einzelantrieb 31 und so die Klappenwelle 21 stillgesetzt sowie die Blasluftzufuhr zur Blasstange 22 unterbrochen. Danach können die Vorlaufbogen 38 durch die Trennsauger 13 vom Stapel 9 vereinzelt und mit Hilfe der Transportsauger 14 in Transportrichtung 17 gefördert werden.
In Fig. 2 it is shown that above the suction belt table 2, a supply air tank 37 is provided. The flow sheet container 37 is fixed to the frame by means not shown, the suction belt table 2 and can be pivoted as a functional unit about a vertical axis, not shown, and thus spent from the range of Saugbändertischs 2 become. It is also possible to displaceably store the supply air tank 37 in order to be able to remove it from the area of the suction belt table 2 when not in use.
The forerunner tank 37 serves to receive flow sheet 38 and consists of a base plate 39 which is provided on its the forward bend 38 facing side with Kugelblasdüsen. In the sheet feeder 1 facing area of Vortaufbogenbehälters 37 leading edge stops 40, 40 are provided which are arranged at a distance from the base plate 39 so that resting on the base plate 39 flow sheet 38 from the flow sheet container, 37 can be performed, in addition, a sheet guide 47 may be provided can, which realizes a connection between the base plate 39 and Saugbändertisch 2. The leading edge stops 40 are associated with resilient stripping tongues 41, which are designed to be adjustable in height. Laterally, the supply air tank 32 is provided with side stops 42 and on the side facing away from the sheet feeder 1 with Hiriterkantenanschlägen 43. The side and the rear edge stops 42, 43 are slidably associated with the base plate 39 so that they can be adjusted to the respective format for processing. The side stops 42, the trailing edge stops 43 and the leading edge stops 40 are provided on the forward bend 38 side in the lower section with blowing nozzles for Vorlockern located in the flow sheet container 37 flow sheet 38. In the area of the leading edge stops 40 is provided in the base plate 39 has a recess, in which a suction roll 44 is mounted. The suction roller 44 can be driven by a fourth individual drive 45 via a freewheel 46. The fourth individual drive 45 is controlled by the processing electronics 33 of the sheet feeder 1.
In an isochronous tracking of the sheet feeder 1 is driven by the separation separator 13, driven by the sheet separator 12 associated first single drive 19, the topmost sheet 8 separated from the stack 9 and transferred to the transport suction 14, which promote the separated sheet 8 in the transport direction 17. The separation of the sheet 8 is supported by that blower 36 of the stack 9 loosened and blown by further blower 36 of each of the transport suckers 14 funded sheet 8. The conveyed by the transport suckers 14 sheet 8 are guided by the clocking clock rollers 29 against the drive roller 23 and then released from the transport suckers 14. The flap shaft 21, driven by the third individual drive 31, pivoted out of the path of the sheet 8 and the Blasluftzufuhr to Blasstange 22 is interrupted. The guided by the clock rollers 29 against the drive roller 23 sheets 8 are constantly acted upon by the suction belts 26, which via the suction box 26 with negative pressure be, recorded and underlaid on the feed table 3 and transported with the leading edge against the front position mark 4 in working position, the sheets 8 are detected by the control device 32.
If a number of feed sheet 38 are promoted in the sheet processing machine, the sheet feed from the sheet feeder 1 is interrupted, the link between machine control 34 and processing electronics 33 solved and the sheet feeder 1 stopped, with the suction and Blasluftzufuhr to sheet separator 12 and the Btastuftzufuhr to the horns 36 interrupted; while the suction box 25 is further subjected to negative pressure. Subsequently, the number of the sheet-processing machine to be supplied feed sheet 38 and a start command in the processing electronics 33 is input via a built-in processing electronics 33 preselector. As a result, by means of the processing electronics 33, the actuator 16 is activated and lifted by the sheet separator 12 from the surface of the stack 9: Also, the second single drive 28 and the third single drive 31 are activated, the direction of rotation of the second single drive 28 and thus the direction of rotation of the Suction belts 26 leading drive roller 23 is reversed. In addition, the fourth individual drive 45 is activated and applied to the Vorbogenbogenbehälter 37 associated blowing nozzles, ball valve nozzles with blowing air and the suction roller 44 with suction. Furthermore, the blow rod 22 blowing air is supplied. Since the clock rollers 29 are connected on the drive side to the drive roller 23, these are clocked controlled against the drive roller 23. In principle, it is also possible to assign the clock rollers 29 to a separate drive and to control this by the processing electronics 33.
This can be detected by the suction roller 44 of the respective lowermost Preliminary arc 38 and discharged through the gap formed between the base plate 39 and leading edge stops 40, the Abstreifzungen 41 prevent double sheet withdrawals. Each separated from the suction roller 44 feed sheet 38 is guided by the sheet guide 47 on the suction belt table 2 and detected by the suction belts 26. By the suction roller 44, a transport speed is realized which is equal to or slightly lower than the transport speed of the suction belts 26, so that the flow sheets 38 can be pulled by the suction belts 26 from the supply air tank 37, wherein the freewheel 46 responds. The feed sheet 38 detected by the suction belts 26 is transported against the transport direction 17 onto the stack 9. In this case, the transport is supported by the clock rollers 29, which are lowered in cycles, and by the flap shaft 21, which pushes the respective flow sheet 38 on the stack 9 by means of its pivotal movement.
The transport of the flow sheet 38 to the stack 9 is supported by the outgoing from the blow bar 22, directed approximately opposite to the transport direction 17 blast air flow. On the stack 9, the flow sheets 38 are centered by the trailing edge stops 15 and by the side plates 20 or guide elements 20.1.
Has a flow sheet 38 leave the suction roller 44, the now lowest feed sheet 38 is discharged in the flow sheet container 37 until the predetermined number of feed sheet 38 is reached. Thereafter, the fourth individual drive 45 is stopped, while the suction belts 26 promote the last forward bend 38 on the stack 9. Also, the suction air to the suction roll 44 and the Blasluftzufuhr to the nozzles of the flow sheet container 37 can be interrupted. By promoting the stack 9 feed sheet 38, the height level of the stack 9 is changed. This change is detected by the scanning device 18 and lowered the stack 9 by means of the elevator, not shown, and thus maintained a corresponding level of work.
After the last forward sheet 38 has been placed on the stack 9, the second single drive 28, so that the suction belts 26 and the clock rollers 29, and the third single drive 31 and so the flap shaft 21 is stopped and the Blasluftzufuhr the Blasstange 22 interrupted. Thereafter, the flow sheet 38 can be singled by the separating sucker 13 from the stack 9 and promoted by means of the transport suction 14 in the transport direction 17.

Dazu wird durch den Stellantrieb 16 der Bogentrenner 12 in seine Arbeitsposition abgesenkt, die Saug- und Blasluftzuführung zum Bogentrenner 12 sowie die Blasluftzufuhr zu den Bläsern 36 aktiviert. Gleichzeitig werden die Einzelantriebe 19, 28, 31 aktiviert, wobei die ursprüngliche Drehrichtung des zweiten Einzelantriebs 28 wieder hergestellt wird, so dass die Vorlaufbogen 38 vom Stapel 9 in Transportrichtung 17 abgefördert und den Vordermarken 4 zugeführt werden können. Nach dem Ausrichten des ersten Vorlaufbogens 38 an den Vordermarken 4 wird die Verknüpfung zwischen der Verarbeitungselektronik 33 und der Maschinensteuerung 34 wieder hergestellt und der Bogenanleger 1 mit dem Saugbändertisch 2 innerhalb eines Arbeitstaktes zugeschaltet.
Nach dem Abfördern der auf dem Stapel 9 befindlichen Vorlaufbogen 38 ist es möglich, den Bogentrenner 12 stillzusetzen und damit das Zuführen von Bogen 8 zu vermeiden. Danach können z.B. nochmals Vorlaufbogen 38 aus dem Vorlaufbogenbehälter 37 entnommen und dem Stapel 9 zugeführt werden. Es ist aber auch möglich, nach dem Abfördern der Vorlaufbogen 38 den Bogentrenner 12 nicht stillzusetzen, sondern ohne eine Lücke den Vorlaufbogen 38 die Bogen 8 nachzuführen.
For this purpose, the sheet separator 12 is lowered by the actuator 16 in its working position, the suction and Blasluftzuführung to the sheet separator 12 and the Blasluftzufuhr to the fans 36 activated. At the same time, the individual drives 19, 28, 31 are activated, wherein the original direction of rotation of the second individual drive 28 is restored, so that the feed sheet 38 can be conveyed away from the stack 9 in the transport direction 17 and the front marks 4 can be supplied. After aligning the first leader sheet 38 to the front marks 4, the link between the processing electronics 33 and the machine control 34 is restored and the sheet feeder 1 connected to the suction belt table 2 within a working cycle.
After conveying off the stack 9 located on the feed sheet 38, it is possible to stop the sheet separator 12 and thus avoid the feeding of sheet 8. Thereafter, for example, further supply sheets 38 can be removed from the supply air tank 37 and fed to the stack 9. But it is also possible, after the discharge of the flow sheet 38, the sheet separator 12 does not stop, but without a gap the forward sheet 38, the sheet 8 track.
