Zunächst Bezug nehmend auf Fig. 1 umfasst eine dort dargestellte Wellpappe-Anlage eine Maschine 1 zur Herstellung einer einseitig kaschierten Wellpappe-Bahn 2.Referring first to Fig. 1 a corrugated board plant shown there comprises a machine 1 for producing a single-faced corrugated board web 2.

Von einer ersten Abrolleinrichtung 3 wird eine erste, vorzugsweise endlose, Materialbahn 4 über eine Vorheizeinrichtung 5 der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 zugeführt. Die erste Materialbahn 4 stellt eine Deckbahn für die in der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 erzeugte einseitig kaschierte Wellpappe-Bahn 2 dar.From a first unwinding device 3, a first, preferably endless, web 4 is fed via a preheating device 5 of the machine 1 for producing the single-faced laminated corrugated web 2. The first material web 4 represents a cover sheet for the one-sided laminated corrugated web 2 produced in the machine 1 for producing the single-faced laminated corrugated web 2.

Die erste Materialbahn 4 wird in der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 mit einer zweiten, vorzugsweise endlosen, Materialbahn 6 zusammengeführt, die von einer zweiten Abrolleinrichtung 7 abgerollt wird.The first material web 4 is combined in the machine 1 for producing the single-faced laminated corrugated web 2 with a second, preferably endless, material web 6, which is unrolled by a second unwinding device 7.

In der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 wird die zweite Materialbahn 6 zwischen zwei benachbart zueinander angeordneten Riffelwalzen 8 zur Erzeugung einer Wellung bzw. Riffelung hindurchgeführt. Die zweite Materialbahn 6 liegt so nach dieser Durchführung durch einen Riffelspalt der Riffelwalzen 8 als Wellbahn vor und weist abwechselnd Wellenspitzen und Wellentäler auf.In the machine 1 for producing the single-faced laminated corrugated web 2, the second material web 6 is guided between two corrugated rolls 8 arranged adjacent to one another to produce a corrugation. The second material web 6 is located after this Passing through a corrugated gap of the corrugating rolls 8 as a corrugated web before and has alternately wave peaks and troughs.

Anschließend wird die Wellbahn 6 in der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 von einer Beleimungseinrichtung 9 beleimt, deren Leimauftragswalze mit der oberen Riffelwalze 8 einen Beleimungsspalt ausbildet.Subsequently, the corrugated web 6 is glued in the machine 1 for producing the one-sided laminated corrugated web 2 by a gluing device 9 whose glue applicator roll forms a gluing gap with the upper corrugating roll 8.

Die beleimte Wellbahn 6 wird anschließend in der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 mit der ersten Materialbahn 4 in einem Andrückspalt 10 zusammengedrückt, der zwischen der oberen Riffelwalze 8 und einer in der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 angeordneten Andrückeinrichtung 11 ausgebildet ist. So werden die erste Materialbahn 4 und die Wellbahn 6 unter Bildung der, insbesondere endlosen, einseitig kaschierten Wellpappe-Bahn 2 leimend miteinander verbunden.The glued corrugated web 6 is then compressed in the machine 1 for producing the one-sided laminated corrugated web 2 with the first web 4 in a nip 10, between the upper corrugating roll 8 and one in the machine 1 for producing the one-sided laminated corrugated web 2 arranged pressing device 11 is formed. Thus, the first material web 4 and the corrugated web 6 are connected to form the, in particular endless, one-sided laminated corrugated board web 2 gluing together.

Der Maschine 1 zur Herstellung der einseitig kaschierten Wellpappe-Bahn 2 ist eine Vorheizanordnung 12 mit zwei übereinander angeordneten, beheizbaren Heizwalzen 13 nachgeordnet.The machine 1 for producing the single-faced laminated corrugated web 2 is a preheating 12 arranged with two superimposed, heated heating rollers 13 downstream.

Stromaufwärts zu der Vorheizanordnung 12 ist eine dritte Abrolleinrichtung 14 für eine dritte, vorzugsweise endlose, Materialbahn 15 angeordnet. Die dritte Materialbahn 15 bildet eine Kaschierbahn.Upstream of the preheating arrangement 12, a third unwinding device 14 is arranged for a third, preferably endless, material web 15. The third material web 15 forms a laminating path.

Die einseitig kaschierte Wellpappe-Bahn 2 und die dritte Materialbahn 15 werden durch die Vorheizanordnung 12 transportiert. Sie umschlingen in der Vorheizanordnung 12 beide teilweise eine Heizwalze 13 und werden dabei erwärmt.The single-faced laminated corrugated web 2 and the third material web 15 are transported through the preheating 12. They both wrap around a heating roller 13 in the preheating arrangement 12 and are heated in the process.

Stromabwärts zu der Vorheizanordnung 12 hat die Wellpappe-Anlage ein Leimwerk 16 mit einer Beleimungswalze 17, die teilweise in ein Leimbad 18 getaucht ist. Die einseitig kaschierte Wellpappe-Bahn 2 befindet sich mit ihrer Wellbahn 6 in direktem Kontakt mit der Beleimungswalze 17, so dass dort deren Wellenspitzen beleimt werden.Downstream of the preheat assembly 12, the corrugator has a gluing unit 16 with a gluing roller 17 partially submerged in a glue bath 18. The single-faced laminated corrugated web 2 is located with its corrugated web 6 in direct contact with the gluing roller 17, so that there the shaft tips are glued.

Stromabwärts zu dem Leimwerk 16 hat die Wellpappe-Anlage eine Heiz-Andrückvorrichtung 19, die einen horizontalen Tisch 20 mit Heizplatten (nicht dargestellt) umfasst. Oberhalb des Tisches 20 hat die Heiz-Andrückvorrichtung 19 einen endlosen Andrückgurt 21, der um Walzen 22 geführt und angetrieben ist. Zwischen dem Andrückgurt 21 und dem Tisch 20 ist ein Andrückspalt 23 ausgebildet, durch den die einseitig kaschierte Wellpappe-Bahn 2 und die dritte Materialbahn 15 geführt und unter Bildung einer dreilagigen, insbesondere endlosen, Wellpappe-Bahn 24 leimend miteinander verbunden werden.Downstream of the gluing unit 16, the corrugating machine has a heating presser 19 comprising a horizontal table 20 with heating plates (not shown). Above the table 20, the heating-pressing device 19 has an endless pressure belt 21 which is guided and driven around rollers 22. Between the pressure belt 21 and the table 20, a pressure gap 23 is formed, through which the corrugated web 2 and the third material web 15 laminated on one side are bonded together to form a three-ply, in particular endless, corrugated web 24.

Stromabwärts zu der Heiz-Andrückvorrichtung 19 weist die Wellpappe-Anlage bevorzugt eine Kurz-Querschneidevorrichtung 25 auf, die einerseits zum sicheren Entfernen von Anfahrabfall und andererseits zur Durchführung von Auftrags- bzw. Formatwechseln dient.Downstream of the heating-pressing device 19, the corrugated board plant preferably has a short cross-cutting device 25, which on the one hand serves to safely remove starting waste and on the other hand to carry out order or format changes.

Die Wellpappe-Anlage umfasst außerdem eine Längsschneide-Rillvorrichtung 26, die stromabwärts zu der Kurz-Querschneidevorrichtung 25, sofern vorhanden, angeordnet ist und zwei hintereinander angeordnete Rillstationen 27 sowie zwei hintereinander angeordnete Längsschneidestationen 28 umfasst.The corrugating machine further comprises a longitudinal cutting and scoring device 26 which is arranged downstream of the short cross cutting device 25, if present, and comprises two scoring stations 27 arranged one behind the other as well as two longitudinal cutting stations 28 arranged one behind the other.

Stromabwärts zu der Längsschneide-Rillvorrichtung 26 umfasst die Wellpappe-Anlage eine Weiche 29, in der längsgeschnittene, insbesondere endlose, Teilbahnen 30, 31 aus der dreilagigen Wellpappe-Bahn 24 voneinander räumlich getrennt werden.Downstream of the longitudinal cutting and scoring device 26, the corrugated board installation comprises a switch 29, in which longitudinally cut, in particular endless, partial webs 30, 31 are spatially separated from the three-ply corrugated web 24.

Die Teilbahnen 30, 31 werden anschließend einer der Weiche 29 nachgeordneten Querschneideeinrichtung 32 zugeführt. Die Querschneideeinrichtung 32 hat ein erstes bzw. unteres Querschneide-Walzenpaar 33 zur Querdurchtrennung der ersten bzw. unteren Teilbahn 30. Ferner umfasst die Querschneideeinrichtung 32 ein zweites bzw. oberes Querschneide-Walzenpaar 34 zur Querdurchtrennung der zweiten bzw. oberen Teilbahn 31. Jedes Querschneide-Walzenpaar 33, 34 weist zwei drehangetriebene Walzen mit einem sich radial nach außen erstreckenden Querschneidemesser auf. Die Querschneidemesser eines Querschneide-Walzenpaars 33, 34 wirken zur Querdurchtrennung der jeweiligen Teilbahn 30 bzw. 31 schneidend zusammen, wodurch aus der Teilbahn 30 bzw. 31 Wellpappe-Bögen 35 erzeugt werden.The partial webs 30, 31 are then fed to a cross-cutting device 32 downstream of the switch 29. The cross-cutting device 32 has a first or lower cross-cutting roller pair 33 for transverse cutting through the first and lower partial webs 30. Furthermore, the cross-cutting device 32 comprises a second or upper cross-cutting roller pair 34 for transverse cutting through the second or upper partial web 31. Roller pair 33, 34 has two rotationally driven rollers with a radially outwardly extending transverse cutting blade. The cross-cutting blades of a cross-cutting roller pair 33, 34 cooperate to cut transversely through the respective partial web 30 or 31, whereby corrugated cardboard sheets 35 are produced from the partial web 30 or 31.

Zum entsprechenden Betätigen der Querschneideeinrichtung 32 können in der Wellpappe-Anlage Passmarken-Sensoren angeordnet sein, die Passmarken auf der einseitig kaschierten Wellpappe-Bahn 2 bzw. auf der dreilagigen Wellpappe-Bahn 24 erfassen.For the corresponding actuation of the cross-cutting device 32, registration marks sensors can be arranged in the corrugated board system which detect registration marks on the corrugated board web 2 laminated on one side or on the three-ply corrugated board web 24.

Die aus der ersten Teilbahn 30 erzeugten Wellpappe-Bögen 35 werden über ein erstes bzw. unteres Förderband 36 und die aus der zweiten Teilbahn 31 erzeugten Wellpappe-Bögen 35 werden über ein zweites bzw. oberes Förderband 37 einer Bogen-Ablageanordnung 38 geschuppt zugeführt. Das untere Förderband 36 ist also dem unteren Querschneide-Walzenpaar 33 zugeordnet, während das obere Förderband 37 dem oberen Querschneide-Walzenpaar 34 zugeordnet ist. Das untere Förderband 36 fördert die durch das untere Querschneide-Walzenpaar 33 erzeugten Wellpappe-Bögen 35 zu einer ersten Bogen-Ablagevorrichtung 39 der Bogen-Ablageanordnung 38, während das obere Förderband 37 die durch das obere Querschneide-Walzenpaar 34 erzeugten Wellpappe-Bögen 35 zu einer zweiten Bogen-Ablagevorrichtung 40 der Bogen-Ablageordnung 38 fördert.The corrugated sheets 35 produced from the first partial web 30 are fed via a first or lower conveyor belt 36 and the corrugated sheets 35 produced from the second partial web 31 are fed to a sheet storage arrangement 38 via a second or upper conveyor belt 37. The lower conveyor belt 36 is thus assigned to the lower transverse cutting roller pair 33, while the upper conveyor belt 37 to the upper transverse cutting roller pair 34 is assigned. The lower conveyor belt 36 conveys the corrugated sheets 35 produced by the lower cross cutting roller pair 33 to a first sheet depositing device 39 of the sheet tray assembly 38, while the upper conveyor belt 37 generates the corrugated sheets 35 produced by the upper cross cutting roller pair 34 a second sheet-storage device 40 of the sheet-storage order 38 promotes.

Die erste Bogen-Ablagevorrichtung 39 und die zweite Bogen-Ablagevorrichtung 40 sind identisch ausgeführt. Sie sind in Fig. 1 nur beispielhaft dargestellt. Nachfolgend wird daher der Kürze halber nur die erste Bogen-Ablagevorrichtung 39 im Detail, insbesondere unter Bezugnahme auf die Fig. 2 bis 6, beschrieben.The first sheet deposition device 39 and the second sheet deposition device 40 are made identical. They are in Fig. 1 shown only as an example. Hereinafter, therefore, for the sake of brevity, only the first sheet storage device 39 in detail, in particular with reference to the Fig. 2 to 6 , described.

Die erste Bogen-Ablagevorrichtung 39 weist ein gegenüber einem Boden 41 abgestütztes Gestell 42 auf, das wiederum zwei einander gegenüberliegende Seitenträger 43, 44 umfasst. Zwischen diesen Seitenträgern 43, 44 erstreckt sich oben ein Querträger 45 des Gestells 42.The first sheet depositing device 39 has a frame 42 which is supported with respect to a base 41 and which in turn comprises two side supports 43, 44 lying opposite one another. Between these side beams 43, 44 extends above a cross member 45 of the frame 42nd

Die erste Bogen-Ablagevorrichtung 39 weist außerdem einen Stapelboden 46 auf, der zwischen deren Seitenträgern 43, 44 angeordnet ist und horizontal verläuft. Der Stapelboden 46 ist höhenverstellbar. Dazu hat die erste Bogen-Ablagevorrichtung 39 eine entsprechende Höhen-Verstelleinrichtung (nicht dargestellt).The first sheet-storing device 39 also has a stack bottom 46, which is arranged between the side supports 43, 44 and extends horizontally. The stack bottom 46 is height adjustable. For this purpose, the first sheet storage device 39 has a corresponding height adjustment device (not shown).

Durch den Stapelboden 46 und die Seitenträger 43, 44 ist eine Bogen-Stapelkammer 47 der ersten Bogen-Ablagevorrichtung 39 räumlich begrenzt.Through the stack bottom 46 and the side support 43, 44, a sheet stacking chamber 47 of the first sheet storage device 39 is spatially limited.

Die erste Bogen-Ablagevorrichtung 39 hat ferner eine Bogen-Auszugseinrichtung 48, die günstigerweise an deren Gestell 43 angeordnet ist. Die Bogen-Auszugseinrichtung 48 weist ein endloses einteiliges Gurtband 49 auf, das im Betrieb in einer Umlaufrichtung 50 geführt ist.The first sheet depositing device 39 further has a sheet extracting device 48, which is conveniently arranged on the frame 43. The sheet extraction device 48 has an endless one-piece webbing 49, which is guided in operation in a circumferential direction 50.

Die Bogen-Auszugseinrichtung 48 umfasst eine erste Umlenkwalze 51, die benachbart zu einem stromabwärtigen Abgabebereich des unteren Förderbands 36 angeordnet ist. Sie weist ferner eine zweite Umlenkwalze 52 auf, die unmittelbar benachbart zu der Bogen-Stapelkammer 47 in etwa auf vertikaler Höhe der ersten Umlenkwalze 51 angeordnet ist und im Durchmesser sehr klein ist. Die Bogen-Auszugseinrichtung 48 umfasst außerdem eine dritte Umlenkwalze 53, die unmittelbar benachbart zu der Bogen-Stapelkammer 47 unterhalb der zweiten Umlenkwalze 52 angeordnet ist. Die dritte Umlenkwalze 53 ist gegenüber der zweiten Umlenkwalze 52 in Richtung auf die erste Umlenkwalze 51, vorzugsweise zwischen 1 mm und 10 mm, bevorzugter zwischen 2 mm und 6 mm, leicht rückversetzt. Ferner hat die erste Bogen-Auszugseinrichtung 48 eine Spannwalze 54 zum Spannen des Gurtbands 49 und eine vierte Umlenkwalze 55, die zwischen der dritten Umlenkwalze 53 und der ersten Umlenkwalze 51 angeordnet sind.The sheet extracting device 48 includes a first deflecting roller 51 disposed adjacent to a downstream discharge portion of the lower conveyor belt 36. It also has a second deflection roller 52, which is arranged immediately adjacent to the sheet stacking chamber 47 approximately at the vertical height of the first guide roller 51 and is very small in diameter. The sheet extracting device 48 also includes a third deflecting roller 53, which is disposed immediately adjacent to the sheet stacking chamber 47 below the second deflecting roller 52. The third deflecting roller 53 is slightly offset from the second deflecting roller 52 in the direction of the first deflecting roller 51, preferably between 1 mm and 10 mm, more preferably between 2 mm and 6 mm. Further, the first sheet extracting means 48 has a tension roller 54 for tensioning the webbing 49 and a fourth deflecting roller 55 disposed between the third deflecting roller 53 and the first deflecting roller 51.

Die erste Umlenkwalze 51, die zweite Umlenkwalze 52, die dritte Umlenkwalze 53 und die Spannwalze 54 sowie die vierte Umlenkwalze 55 sind an zwei einander gegenüberliegenden Rahmenwänden 56 der Bogen-Auszugsrichtung 48, die wiederum an dem Gestell 42 befestigt sind, drehbar gelagert. Ihre Drehachsen verlaufen parallel zueinander und senkrecht zu der Umlaufrichtung 50 des Gurtbands 49.The first guide roller 51, the second guide roller 52, the third guide roller 53 and the tension roller 54 and the fourth guide roller 55 are rotatably mounted on two opposite frame walls 56 of the sheet extension direction 48, which in turn are secured to the frame 42. Their axes of rotation parallel to each other and perpendicular to the direction of rotation 50 of the webbing 49th

In Bezug auf die Umlaufrichtung 50 ist der ersten Umlenkwalze 51 die zweite Umlenkwalze 52 nachgeordnet, der wiederum in Bezug auf die Umlaufrichtung 50 die dritte Umlenkwalze 53 nachgeordnet ist. Der dritten Umlenkwalze 53 ist bezogen auf die Umlaufrichtung 50 die Spannwalze 54 nachgeordnet, der wiederum in Bezug auf die Umlaufrichtung 50 die vierte Umlenkwalze 55 nachgeordnet ist. Das Gurtband 49 ist um die erste Umlenkwalze 51, die zweite Umlenkwalze 52, die dritte Umlenkwalze 53, die Spannwalze 54 und die vierte Umlenkwalze 55 geführt und liegt an diesen umfangsseitig bereichsweise an.With respect to the direction of rotation 50 of the first guide roller 51, the second guide roller 52 is arranged downstream, which in turn with respect to the direction of rotation 50, the third guide roller 53 is arranged downstream. The third guide roller 53 is located downstream of the tensioning roller 54 in relation to the direction of rotation 50, which in turn is arranged downstream of the fourth guide roller 55 in relation to the direction of rotation 50. The webbing 49 is guided around the first deflecting roller 51, the second deflecting roller 52, the third deflecting roller 53, the tensioning roller 54 and the fourth deflecting roller 55 and abuts against these peripherally in regions.

Ferner hat die Bogen-Auszugseinrichtung 48 eine Kopplungswalze 57, die sich zwischen den Rahmenwänden 56 erstreckt und an diesen drehbar gelagert ist (Fig. 6). Die Kopplungswalze 57 erstreckt sich ebenfalls senkrecht zu der Umlaufrichtung 50 des Gurtbands 49.Furthermore, the sheet extraction device 48 has a coupling roller 57 which extends between the frame walls 56 and is rotatably mounted thereon ( Fig. 6 ). The coupling roller 57 also extends perpendicular to the direction of rotation 50 of the webbing 49th

Die Bogen-Auszugseinrichtung 48 umfasst außerdem eine Antriebswelle 58, die Bestandteil eines Antriebs 59 und drehantreibbar ist (Fig. 6). Ein endloser Antriebsgurt 60 ist um die Antriebswelle 58, die erste Umlenkwalze 51 und die Kopplungswalze 57 außerhalb einer Rahmenwand 56 geführt. Die Drehachse der Antriebswelle 58 verläuft parallel zu der Drehachse der ersten Umlenkwalze 51. Bei Betätigung des Antriebs 59 wird dessen Antriebswelle 58 in Drehung versetzt, was wiederum aufgrund der Kopplung über den Antriebsgurt 60 zu einem Drehantrieb der ersten Umlenkwalze 51 und der Kopplungswalze 57 führt. Durch die Kopplungswalze 57 ist die erste Umlenkwalze 51 beidseitig antreibbar. Das Gurtband 49 ist so in der Umlaufrichtung 50 kontinuierlich antreibbar.The sheet extraction device 48 also includes a drive shaft 58 which is part of a drive 59 and is rotationally drivable ( Fig. 6 ). An endless drive belt 60 is guided around the drive shaft 58, the first guide roller 51 and the coupling roller 57 outside a frame wall 56. The axis of rotation of the drive shaft 58 is parallel to the axis of rotation of the first guide roller 51. Upon actuation of the drive 59 whose drive shaft 58 is rotated, which in turn leads due to the coupling via the drive belt 60 to a rotary drive of the first guide roller 51 and the coupling roller 57. By the coupling roller 57, the first guide roller 51 can be driven on both sides. The webbing 49 is thus continuously driven in the circumferential direction 50.

Die Bogen-Auszugseinrichtung 48 weist einen Bogen-Antransportbereich 61 auf, der zwischen der ersten Umlenkwalze 51 und der zweiten Umlenkwalze 52 vorliegt. Der Bogen-Antransportbereich 61 erstreckt sich somit zwischen dem unteren Förderband 36 und der Bogen-Stapelkammer 47. Er schließt sich unmittelbar an das untere Förderband 36 an. In dem Bogen-Antransportbereich 61 verläuft das Gurtband 49 von dem unteren Förderband 36 zu der Bogen-Stapelkammer 47 gerade und leicht nach unten. Der Bogen-Antransportbereich 61 endet bei der zweiten Umlenkwalze 52.The sheet extraction device 48 has a sheet feed region 61, which is present between the first guide roller 51 and the second guide roller 52. The sheet feeding portion 61 thus extends between the lower conveyor belt 36 and the sheet stacking chamber 47. Er joins directly to the lower conveyor belt 36. In the sheet-feeding region 61, the webbing 49 extends straight from the lower conveyor belt 36 to the sheet stacking chamber 47 and slightly downward. The sheet feed region 61 ends at the second guide roller 52.

Stromabwärts zu dem Bogen-Antransportbereich 61 in Bezug auf die Umlaufrichtung 50 hat die Bogen-Auszugseinrichtung 48 einen Bogen-Stapelbereich 69, der zwischen der zweiten Umlenkwalze 52 und der dritten Umlenkwalze 53 vorliegt. Der Bogen-Stapelbereich 69 erstreckt sich unmittelbar benachbart an der Bogen-Stapelkammer 47 entlang. In dem Bogen-Stapelbereich 69 verläuft das Gurtband 49 von der zweiten Umlenkwalze 52 gerade nach unten. Das Gurtband 49 schließt dort gegenüber einer Vertikalen V einen Winkel w ein, der zwischen 1° und 8° liegt. Es erstreckt sich in dem Bogen-Stapelbereich 69 gerade über eine Länge 1, die zwischen 6 cm und 40 cm, bevorzugter zwischen 8 cm und 15 cm, liegt.Downstream of the sheet feeding region 61 with respect to the circulating direction 50, the sheet drawing-out device 48 has a sheet stacking portion 69 provided between the second deflecting roller 52 and the third deflecting roller 53. The sheet stacking portion 69 extends immediately adjacent to the sheet stacking chamber 47 along. In the sheet stacking area 69, the webbing 49 extends straight down from the second deflecting roller 52. The webbing 49 includes there against a vertical V at an angle w, which is between 1 ° and 8 °. It extends in the sheet stacking area 69 just over a length 1 which is between 6 cm and 40 cm, more preferably between 8 cm and 15 cm.

Stromabwärts zu dem Bogen-Stapelbereich 69 in Bezug auf die Umlaufrichtung 50 hat die Bogen-Auszugseinrichtung 48 einen Rücklaufbereich 62. Der Rücklaufbereich 62 erstreckt sich zwischen der dritten Umlenkwalze 53 und der ersten Umlenkwalze 51. In dem Rücklaufbereich 62 befinden sich die Spannwalze 54 und die vierte Umlenkwalze 55. In dem Rücklaufbereich 62 verläuft das Gurtband 49 von der dritten Umlenkwalze 53 zu der ersten Umlenkwalze 51 zurück. Dort verläuft das Gurtband 49 zumindest bereichsweise gegenüberliegend zu dem Gurtband 49 in dem Bogen-Antransportbereich 61.Downstream of the sheet stacking area 69 with respect to the direction of rotation 50, the sheet extractor 48 has a return area 62. The return area 62 extends between the third deflecting roller 53 and the first deflecting roller 51. In the return area 62 are the tensioning roller 54 and fourth guide roller 55. In the return region 62, the webbing 49 extends from the third guide roller 53 to the first guide roller 51 back. There, the webbing 49 extends at least partially opposite to the webbing 49 in the sheet-feed area 61st

Das Gurtband 49 hat eine nach außen gewandte Außenseite 63 und eine dieser gegenüberliegende Innenseite 64. Von der Außenseite 63 gehen mehrere endlose Aufnahmeaussparungen 65 des Gurtbands 49 aus, die parallel zueinander verlaufen und äquidistant verteilt über eine senkrecht zu der Umlaufrichtung 50 verlaufende Breitenrichtung des Gurtbands 49 angeordnet sind. Die Aufnahmeaussparungen 65 sind identisch ausgebildet. Sie erstrecken sich in der Umlaufrichtung 50 des Gurtbands 49. Die Aufnahmeaussparungen 65 sind in der Breitenrichtung durch einander gegenüberliegende Flanken des Gurtbands 49 begrenzt. Sie haben eine gleichbleibende Breite bzw. Weite. Im Bereich der Aufnahmeaussparungen 65 hat somit das Gurtband 49 jeweils eine reduzierte, gleichbleibende Dicke.The webbing 49 has an outwardly facing outer side 63 and an inner side 64 opposite the latter. From the outer side 63, there are several endless receiving recesses 65 of the webbing 49, which run parallel run to each other and are arranged equidistantly distributed over a direction perpendicular to the direction of rotation 50 extending width direction of the webbing 49. The receiving recesses 65 are identical. They extend in the direction of rotation 50 of the webbing 49. The receiving recesses 65 are bounded in the width direction by opposing flanks of the webbing 49. They have a constant width or width. In the area of the receiving recesses 65, the webbing 49 thus has a reduced, constant thickness.

Ferner hat die erste Bogen-Ablagevorrichtung 39 eine Bogen-Rückhalteeinrichtung 66. Die Bogen-Rückhalteeinrichtung 66 umfasst einen Querträger 67, der sich über die gesamte Breite des Gurtbands 49 und senkrecht zu der Umlaufrichtung 50 des Gurtbands 49 erstreckt. Der Querträger 67 ist an den Rahmenwänden 56 bzw. dem Gestell 42 angeordnet. Er verläuft unterhalb der dritten Umlenkwalze 53 und benachbart zu dieser. Der Querträger 67 erstreckt sich horizontal.Furthermore, the first sheet depositing device 39 has a bow retainer 66. The bow retainer 66 comprises a cross member 67 which extends across the entire width of the webbing 49 and perpendicular to the direction of rotation 50 of the webbing 49. The cross member 67 is disposed on the frame walls 56 and the frame 42. He runs below the third guide roller 53 and adjacent to this. The cross member 67 extends horizontally.

Von dem Querträger 67 springt eine Vielzahl von Bogen-Rückhalteelementen 68 der Bogen-Rückhalteeinrichtung 66 fingerartig nach oben bzw. vertikal hervor. Die Bogen-Rückhalteelemente 68 sind balkenartig ausgeführt und erstrecken sich unten entlang des Bogen-Stapelbereichs 69. Sie verlaufen parallel zueinander.From the cross member 67, a plurality of sheet retaining members 68 of the sheet retainer 66 jump upwardly and vertically, respectively. The sheet retention members 68 are bar-shaped and extend down along the sheet stacking area 69. They are parallel to each other.

Jedes Bogen-Rückhalteelement 68 hat ein oberes freies Kopfende 70, das durch eine horizontal verlaufende Kopfkante des jeweiligen Bogen-Rückhalteelements 68 gebildet ist und bei dem Bogen-Stapelbereich 69 vollständig in der benachbarten Aufnahmeaussparung 65 aufgenommen ist.Each sheet retention member 68 has an upper free head end 70 which is formed by a horizontally extending head edge of the respective sheet retention member 68 and is fully received in the sheet receiving portion 65 in the sheet stacking portion 69.

Oberhalb des Bogen-Antransportbereichs 61 hat die erste Bogen-Ablagevorrichtung 39 eine Andrückrolle 71. Die Andrückrolle 71 erstreckt sich horizontal und ist in einer verschwenkbaren Armanordnung 72 frei drehbar gelagert. Sie verläuft benachbart und parallel zu der zweiten Umlaufwalze 52.Above the sheet feed area 61, the first sheet depositing device 39 has a pressure roller 71. The pressure roller 71 extends horizontally and is freely rotatably mounted in a pivotable arm arrangement 72. It runs adjacent and parallel to the second circulation roller 52.

Im Betrieb der Wellpappe-Anlage werden die erzeugten Wellpappe-Bögen 35 von dem unteren Förderband 36 auf das Gurtband 49 überführt, das in der Umlaufrichtung 50 kontinuierlich angetrieben ist. Ein zu stapelnder Wellpappe-Bogen 35 wird so von dem Gurtband 49 in dem Bogen-Antransportbereich 61 in Richtung auf die Bogen-Stapelkammer 47 transportiert. Er gelangt unmittelbar stromaufwärts zu der Bogen-Stapelkammer 47 in einen Zuführspalt 73, der durch die Andrückrolle 71 und das Gurtband 49 bei der zweiten Umlenkwalze 52 ausgebildet ist. Die Andrückrolle 71 liegt dabei mit ihrem Eigengewicht auf dem Wellpappe-Bogen 35 auf.During operation of the corrugating machine, the corrugated sheets 35 produced are transferred from the lower conveyor belt 36 to the webbing 49, which is continuously driven in the direction of rotation 50. A corrugated sheet 35 to be stacked is thus transported from the webbing 49 in the sheet feeding area 61 toward the sheet stacking chamber 47. It passes immediately upstream of the sheet stacking chamber 47 into a feed gap 73 which is formed by the pressure roller 71 and the webbing 49 at the second guide roller 52. The pressure roller 71 rests with its own weight on the corrugated sheet 35.

Wie Fig. 2 zeigt, tritt dann der zu stapelnde Wellpappe-Bogen 35 mit seinem vorauseilenden Ende 74 in die Bogen-Stapelkammer 47 ein. Das vorauseilende Ende 74 wird durch das Gurtband 49 in der Bogen-Stapelkammer 47 von dem Zuführspalt 73 auf einem bereits ordnungsgemäß abgelegten Wellpappe-Bogen 35 bzw. dem Stapelboden 46 weg geschoben. Das vorauseilende Ende 74 des Wellpappe-Bogens 35 verlässt also nach dem Zuführspalt 73 das Gurtband 49. Ein nacheilendes Ende 75 dieses Wellpappe-Bogens 35 liegt in dem Bogen-Stapelbereich 69 anfangs weiterhin auf dem Gurtband 49 auf.As Fig. 2 shows then enters the stacked corrugated sheet 35 with its leading end 74 in the sheet stacking chamber 47 a. The leading end 74 is pushed by the webbing 49 in the sheet stacking chamber 47 of the feed slot 73 on an already properly deposited corrugated sheet 35 and the stack bottom 46 away. The leading end 74 of the corrugated sheet 35 thus leaves the webbing 49 after the feed gap 73. A trailing end 75 of this corrugated sheet 35 is initially in the sheet stacking portion 69 on the webbing 49 on.

Das nacheilende Ende 75 des Wellpappe-Bogens 35 bleibt auch nach dem Durchlauf des Zuführspalts 73 mit dem Gurtband 49 in Kontakt. Es gelangt in den Bogen-Stapelbereich 69 und wird so von dem dort nach unten verlaufenden Gurtband 49 gezielt nach unten auf den bereits ordnungsgemäß abgelegten Bogen 35 bzw. den Stapelboden 46 geführt (Fig. 3).The trailing end 75 of the corrugated sheet 35 remains in contact with the webbing 49 even after passing through the feed nip 73. It enters the sheet stacking area 69 and is thus from the down there running Gurtband 49 targeted down to the already properly filed sheet 35 and the stack bottom 46 guided ( Fig. 3 ).

In dem Bogen-Stapelbereich 69 erreicht das nacheilende Ende 75 des Wellpappe-Bogens 35 zunächst die Kopfenden 70 der Bogen-Rückhalteelemente 68. Das nacheilende Ende 75 des Wellpappe-Bogens 35 gleitet außen geführt an den Bogen-Rückhalteelementen 68 nach unten entlang, die so den Wellpappe-Bogen 35 weiter nach unten führen (Fig. 4). Dabei tritt eine Relativbewegung zwischen dem Wellpappe-Bogen 35 und den Bogen-Rückhalteelementen 68 auf. Das nacheilende Ende 75 des Wellpappe-Bogens 35 liegt vorzugsweise zwischen den Bogen-Rückhalteelementen 68 weiterhin zumindest bereichsweise an dem Gurtband 49 in dem Bogen-Stapelbereich 69 an.In the sheet stacking area 69, the trailing end 75 of the corrugated sheet 35 first reaches the head ends 70 of the sheet retention members 68. The trailing end 75 of the corrugated sheet 35 slides outwardly along the sheet retention members 68 downwardly so forth continue down the corrugated sheet 35 ( Fig. 4 ). In this case, a relative movement between the corrugated sheet 35 and the sheet retention elements 68 occurs. The trailing end 75 of the corrugated sheet 35 is preferably at least partially on the webbing 49 in the sheet stacking area 69 between the sheet retention elements 68 on.

Nachdem bei dem Rücklaufbereich 62 des Gurtbands 49 eingangsseitig in Bezug auf die Umlaufrichung 50 ein durch das Gurtband 49 begrenzter Rücklaufspalt 76 von den Bogen-Rückhalteelementen 68 außen vollständig übergriffen ist, ist dort ein Einzug des Wellpappe-Bogens 35 aus der Bogen-Stapelkammer 47 durch das Gurtband 49 entlang des Rücklaufbereichs 62 ausgeschlossen.After at the return region 62 of the webbing 49 on the input side with respect to the direction of circulation 50 a limited by the webbing 49 return gap 76 is completely overlapped by the sheet retention elements 68 outside, there is a collection of corrugated sheet 35 from the sheet stacking chamber 47 through the webbing 49 along the return area 62 excluded.

Die zweite Bogen-Ablagevorrichtung 40 arbeitet analog.The second sheet storage device 40 operates analogously.

Beim Stapeln wird Stapelboden 46 sukzessive abgesenkt.When stacking stack bottom 46 is lowered gradually.
