In Fig. 1 ist in Seitenansicht ein Bogenanleger 1 mit einer Non-Stop-Einrichtung 2 dargestellt. Die Non-Stop-Einrichtung 2 wird durch einen nicht dargestellten Hilfsstapelaufzug mittels Zugmittel 3 in vertikaler Richtung bewegt. Die Non-Stop-Einrichtung 2 ist unter einem dem Bogenanleger 1 nachgeordneten Bändertisch 4 angeordnet und kann an Führungsschienen 5 auf- und abbewegt werden. Von der Non-Stop-Einrichtung 2 ist weiterhin ein aus Tragstäben 10 bestehender Hilfsstapeltisch 6 gezeigt, der durch eine Stabführung 7 geführt und motorisch entgegen einer Förderrichtung 8 in den Stapelbereich 9 verbracht und in Förderrichtung 8 aus diesem herausgeführt werden kann. Wenn die Tragstäbe 10 sich im Stapelbereich 9 befinden, liegen sie mit ihrem freien Ende auf einer an den Zugmitteln 3 angeordneten hinteren Traverse 11 und mit dem der Stabführung 7 zugewandten Bereich auf einer vorderen Traverse 12 auf, an der ebenfalls die Zugmittel 3 angreifen.In Fig. 1, a sheet feeder 1 is shown with a non-stop device 2 in side view. The non-stop device 2 is by means of a Hilfsstapelaufzug not shown means Traction means 3 moves in the vertical direction. The non-stop device 2 is under a the Sheet feeder 1 downstream belt table 4 and arranged on guide rails 5 are moved up and down. Of the non-stop device 2 is still a support rods 10 existing auxiliary stacking table 6 shown, which is guided by a rod guide 7 and motor counter to a conveying direction 8 spent in the stacking area 9 and in the conveying direction 8 can be led out of this. When the support bars 10 are in the stacking area 9, they lie with their free end on one of the traction means 3 arranged rear cross member 11 and with the rod guide 7 facing area on a front cross member 12, on which also the traction means 3 attack.

In der Figur 1 ist der Hilfsstapeltisch 6 in seiner Position im Stapelbereich 9 gezeigt. Auf dem Hilfsstapeltisch 6 liegt ein Restbogenstapel 13, von dessen Oberseite durch eine Bogenvereinzelungseinrichtung 14 Bogen 15 vereinzelt werden. Von der Bogenvereinzelungseinrichtung 14 sind Trennsauger 16 und Transportsauger 17 sowie ein die Oberseite des Restbogenstapels 13 im Bereich der Bogenvereinzelungseinrichtung 14 erfassende Abtasteinrichtung 18 dargestellt. Weiterhin ist ein Hauptbogenstapel 19 dargestellt, der mittels einer Palette 20 auf einer Stapelplatte 21, die sich in einer Stapelübernahmeposition befindet, angeordnet ist. Der Hauptbogenstapel 19 liegt mit seiner Vorderseite an Führungsschienen 22 an. Die Stapelplatte 21 ist an Zugmitteln 23 angeordnet, die mit einem nicht dargestellten Hubwerk verbunden sind.In FIG. 1, the auxiliary stacking table 6 is shown in its position in the stacking area 9. On the Auxiliary stacking table 6 is a remaining sheet stack 13, from the top through a sheet separating device 14 sheets 15 are separated. From the sheet separating device 14 are vacuum cleaner 16 and transport suction 17 and one the top of the rest of the sheet pile 13 in the area of the sheet separating device 14 detecting scanning 18 shown. Furthermore, a main sheet stack 19 is shown, which by means of a pallet 20 on a stacking plate 21, which is located in a Stapelübernahmeposition arranged is. The main sheet stack 19 rests with its front on guide rails 22. The stacking plate 21 is arranged on traction means 23, which is connected to a lifting mechanism, not shown are connected.

Wie allgemein üblich, wird im Bogenanleger 1 ein Hauptbogenstapel 19 mit einer Palette 20 auf der Stapelplatte 21 angeordnet, die über die Zugmittel 23 angehoben wird, bis die Oberfläche des Hauptbogenstapels 19 von der Abtasteinrichtung 18 der Bogenvereinzelungseinrichtung 14 erfasst und der jeweils oberste Bogen 15 von den Trennsaugern 16 angehoben sowie an die Transportsauger 17 übergeben wird, die diesen in Förderrichtung 8 und damit auf den Bändertisch 4 transportieren. Ist der Hauptbogenstapel 19 bis auf einen Restbogenstapel 13 abgetragen, werden die Tragstäbe 10 der Non-Stop-Einrichtung 2 motorisch in den Stapelbereich 9 geführt, so dass diese in den Nuten der Palette 20 geführt sowohl auf der vorderen Traverse 12 als auch auf der hinteren Traverse 11 aufliegen. Durch den über die Zugmittel 3 an den Traversen 11, 12 angreifenden Hilfsstapelaufzug wird das Nachführen des Restbogenstapels 13 im Arbeitstakt realisiert, während die Stapelplatte 21 in ihre untere Position zurückgeführt wird zur Übernahme eines neuen Hauptbogenstapels 19. Nach der Übernahme eines neuen Hauptbogenstapels 19 wird die Stapelplatte 21 angehoben, bis sich die Oberfläche des Hauptbogenstapels 19 mit einer Annäherungsgeschwindigkeit den Tragstäben 10 und damit dem Hilfsstapeltisch 6 annähert.As is customary in the sheet feeder 1, a main sheet stack 19 with a pallet 20 arranged on the stacking plate 21, which is raised by the traction means 23 until the surface of the main sheet stack 19 from the scanner 18 of the sheet singulator 14 detected and raised the top sheet 15 of the vacuum cleaner 16 and is transferred to the transport suction 17, the latter in the conveying direction 8 and thus transport to the belt table 4. Is the main sheet pile 19 except for a remaining sheet stack 13 removed, the support rods 10 of the non-stop device 2 are motorized in the Stacking area 9 is guided so that they are guided in the grooves of the pallet 20 both on the rest front cross member 12 and on the rear cross member 11. By the over the Traction means 3 on the trusses 11, 12 attacking auxiliary stack lift is the tracking realized the residual arc stack 13 in the working cycle, while the stacking plate 21 in its lower Position is returned to take over a new main sheet pile 19. After the Takeover of a new main sheet stack 19, the stacking plate 21 is raised until the surface of the main sheet pile 19 at a closing speed the support rods 10 and thus approaches the auxiliary stacking table 6.

Besitzt der neue Hauptbogenstapel 19, wie in Fig. 2 dargestellt, eine Oberfläche, die im der Bogenvereinzelungseinrichtung 14 zugewandten Bereich höher ist als im der Non-Stop-Einrichtung 2 zugewandten Bereich, werden ein oder mehrere Tragstäbe 10 angehoben und damit ebenfalls der Reststapel 13 in diesem Bereich verschoben, was durch die Abtasteinrichtung 18 erfasst wird. Wird gleichzeitig durch eine der vorderen Traverse 12 zugeordnete, die Oberfläche des Hauptbogenstapels 19 erfassende Sensorik 24 kein Signal generiert, wird die Annäherungsgeschwindigkeit des Hauptbogenstapels 19 auf die Arbeitsgeschwindigkeit umgeschaltet, d.h. Restbogenstapel 13 und Hauptbogenstapel 19 werden synchron angehoben, und nachfolgend der Hilfsstapeltisch 6 schrittweise aus dem Stapelbereich 9 bis zur vollständigen Vereinigung des Restbogenstapels 13 mit dem neuen Hauptbogenstapel 19 geführt. Has the new main sheet stack 19, as shown in Fig. 2, a surface in the Bogenunterzelungseinrichtung 14 facing area is higher than in the non-stop device 2 facing area, one or more support bars 10 are raised and thus also the residual stack 13 is moved in this area, which by the scanning device 18 is detected. Is simultaneously assigned by one of the front traverse 12, the surface of the main sheet stack 19 detecting sensor 24 generates no signal, becomes the approach speed of the main sheet stack 19 to the working speed switched, i. Restbogenstapel 13 and main sheet stack 19 are synchronized lifted, and subsequently the auxiliary stacking table 6 gradually from the stack area 9 to to completely unify the remaining sheet stack 13 with the new main sheet pile 19 led.

Ist die Oberfläche des neuen Hauptbogenstapels 19, wie in Fig. 3 dargestellt, in der Non-Stop-Einrichtung 2 zugewandten Bereich erhöht, wird von der Sensorik 24 ein Signal generiert, während von der Abtasteinrichtung 18 kein Anheben detektiert wird, und die Annäherungsgeschwindigkeit des neuen Hauptbogenstapels 19 wird auf Arbeitsgeschwindigkeit umgeschaltet. Gleichzeitig wird die Bewegungsrichtung des Hilfsstapelaufzuges und damit die der Traversen 11, 12 umgekehrt, bis die Enden der Tragstäbe 10 von der hinteren Traverse 11 gerade abheben, wie in Fig. 3 gestrichelt dargestellt. Danach wird der Hilfsstapeltisch 6 so weit aus dem Stapelbereich 9 zurückgeführt, bis die Spitzen der Tragstäbe 10 nicht mehr auf der hinteren Traverse 11 aufliegen und anschließend die Non-Stop-Einrichtung 2 angehoben, bis die Tragstäbe 10 etwa biegespannungsfrei zwischen dem Hauptbogenstapel 19 und dem Restbogenstapel 13 positioniert sind. Nachfolgend wird die Arbeitsgeschwindigkeit des Restbogenstapels 13 der Arbeitsgeschwindigkeit des Hauptbogenstapels 19 angepasst und die Tragstäbe 10 der Non-Stop-Einrichtung 2 aus dem Stapelbereich 9 herausgeführt und der Restbogenstapel 13 mit dem Hauptbogenstapel 19 vereinigt.If the surface of the new main sheet stack 19, as shown in Fig. 3, in the non-stop device 2 increases, a signal is generated by the sensor 24, while no lift is detected by the scanner 18, and the approach speed of the new main sheet pile 19 becomes on working speed switched. At the same time, the direction of movement of the auxiliary stacking elevator and thus that of the trusses 11, 12 vice versa, until the ends of the support rods 10 from the rear cross member 11 straight off, as shown in phantom in Fig. 3. After that, the auxiliary stacking table 6 so far returned from the stack area 9 until the tips of the support rods 10th no longer rest on the rear cross member 11 and then the non-stop device 2 raised until the support rods 10 approximately free of bending stress between the Main sheet stack 19 and the remaining sheet stack 13 are positioned. Below is the Working speed of the remaining sheet stack 13 of the working speed of the main sheet pile 19 adapted and the support rods 10 of the non-stop device 2 from the stack area 9 led out and the remaining sheet pile 13 combined with the main sheet pile 19.

Es ist auch möglich, zum Erfassen der Oberfläche des Hauptbogenstapels 19 im der Bogenvereinzelungseinrichtung 14 zugewandten Bereich statt die Abtasteinrichtung 18 zu verwenden, die hintere Traverse 11 auf bekannte Weise als Kontaktschiene auszubilden und die Bewegung der Tragstäbe 10 in ihrem der Non-Stop-Einrichtung 2 abgewandten Bereich zu detektieren. Es kann aber auch der hinteren Traverse 11 eine den Verlauf der Oberfläche des neuen Hauptbogenstapels 19 direkt erfassende Sensoreinrichtung zugeordnet werden.It is also possible to detect the surface of the main sheet stack 19 in the sheet singler 14 facing area instead of using the scanner 18, form the rear cross member 11 in a known manner as a contact rail and the Movement of the support rods 10 in their non-stop device 2 remote area detect. But it can also be the rear cross member 11 a the course of the surface be assigned to the new main sheet stack 19 directly detecting sensor device.

Die von der Sensorik 24 und von der Abtasteinrichtung 18 bzw. einer der hinteren Traverse 11 zugeordneten Sensoreinrichtung durch das Erfassen der Oberfläche eines neuen Hauptbogenstapels 19 realisierten Steuersignale werden einer Steuereinrichtung zugeführt. Von der Steuereinrichtung werden erste und zweite Steuersignale generiert, durch die in Abhängigkeit von der Lage der Oberfläche des neuen Bogenstapels 19 die zur Realisierung eines problemlosen Non-Stop-Stapelwechsels erforderlichen Arbeitsschritte gesteuert werden. That of the sensor 24 and the scanner 18 and one of the rear cross member 11 associated sensor device by detecting the surface of a new main sheet pile 19 realized control signals are supplied to a control device. From the control device first and second control signals are generated by the function of from the location of the surface of the new sheet pile 19 for the realization of a required non-stop stack change required operations.
