Description

Die Erfindung betrifft eine Vorrichtung zur Obernahme, Speicherung und Abgabe von Falzprodukten oder Bogenstücken, bei der ein als Transportvorrichtung ausgebildetes flexibles Stahlband, das von einer Vorratsrolle abziehbar, um eine Führungrolle krümmbar und auf eine Speicherrolle aufziehbar ist, vorgesehen ist.The invention relates to a device for receiving, storing and delivering folded products or sheet pieces, in which a flexible steel belt designed as a transport device, which can be pulled off a supply roll, can be bent around a guide roll and can be pulled up onto a storage roll, is provided.

Eine Vorrichtung dieser Art ist bereits aus der europäischen Patentanmeldung 0 387 726 bekannt. Bei dieser Vorrichtung werden ebenfalls elastische Stahlbänder beschrieben, die mit aufgesetzten Greifern taktmäßig Bogenstücke oder Falzprodukte erfassen und auf einer speicherrolle wickelförmig abspeichern können. Sollen die Stahlbänder ohne Bogenstücke oder Falzprodukte als Leerspeicher bzw. auf einer Vorratsrolle aufgewickelt werden, so lassen sie sich naturgemäß nur durch die auf sie aufgesetzten Greifer beabstandet wickeln, d.h. diese Leerspeicher bzw. Vorratsrollen brauchen verhältnismäßig viel Platz. Mit Bogenstücken werden auch herkömmliche bedruckte oder unbedruckte Bogen bezeichnet. Hiervon ausgehend ist es die Aufgabe der vorliegenden Erfindung, eine vereinfachte Vorrichtung zu schaffen, die außerdem eine platzsparende Leerspeicherbildung erlaubt.A device of this type is already known from European patent application 0 387 726. In this device, elastic steel strips are also described which, with attached grippers, capture sheet pieces or folded products in a cyclical manner and can store them in a winding form on a storage roll. If the steel strips are to be wound up as empty storage or on a supply roll without sheet pieces or folded products, they can of course only be wound at a distance by the grippers placed on them, i.e. these empty stores or supply rolls require a relatively large amount of space. Conventional printed or unprinted sheets are also referred to as sheet pieces. Proceeding from this, it is the object of the present invention to create a simplified device which also allows space-saving empty storage formation.

Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst. Weiterbildungen ergeben sich aus der Beschreibung in Verbindung mit der Zeichnung und aus den Unteransprüchen.This object is achieved by applying the features of the characterizing part of patent claim 1. Further developments result from the description in connection with the drawing and from the subclaims.

Im folgenden wird die Erfindung anhand zweier Ausführungsbeispiele beschrieben, wobei Bezug auf die beiliegende Zeichnung genommen wird. Es zeigt:

The invention is described below with reference to two exemplary embodiments, reference being made to the accompanying drawing. It shows:

a second embodiment of the device according to the invention when receiving a shingled stream.

Wie in Fig. 1 dargestellt ist, ist ein Stahlband 1 von einer Vorratsrolle 2 in Pfeilrichtung 3 gezogen und um eine Führungsrolle 4 gekrümmt. Auf dem gekrümmten Teil des Stahlbandes 1 sind tangential abstehende Zungen 5 zu sehen, wobei deren Öffnung in Zug- bzw. Drehrichtung 6 des Stahlbandes 1 weisen.As shown in FIG. 1, a steel strip 1 is drawn from a supply roll 2 in the direction of the arrow 3 and curved around a guide roll 4. Tangentially protruding tongues 5 can be seen on the curved part of the steel strip 1, their opening pointing in the pulling or rotating direction 6 of the steel strip 1.

Wie in Fig. 4 detailliert gezeigt ist, weist das Stahlband 1 in seiner Längsrichtung gleichmäßig beabstandete U-förmige Ausstanzungen 7 auf, die jeweils eine Zunge 5 beranden. Da das Stahlband 1 und mit ihm die Zungen 5 flexibel sind, lassen sich die Zungen 5 bei Krümmung des Stahlbands 1 tangential abstehend öffnen und bei linearer Führung des Stahlbandes 1 in die Ausstanzungen 7 einlegen.As shown in detail in FIG. 4, the steel strip 1 has U-shaped punched-outs 7 which are evenly spaced in its longitudinal direction and which each border a tongue 5. Since the steel strip 1 and with it the tongues 5 are flexible, the tongues 5 can be opened, projecting tangentially when the steel strip 1 is curved, and can be inserted into the punched-out portions 7 when the steel strip 1 is guided linearly.

Unterhalb der Führungsrolle 4 ist ein in bekannter Weise höhenverstellbarer Stapel 8 von Bogenstücken oder Falzprodukten angeordnet, dem auf der der Transportrichtung 9 des Stahlbandes 1 abgekehrten Seite stationäre Anschlagzungen 10, 11 zugeordnet sind. Beiderseits der Führungsrolle 4, wie in Fig. 3 besser zu sehen ist, ist jeweils ortsfest ein Saugkopf 12, 13 angebracht. Die Saugköpfe 12, 13 sind jeweils über eine Düsenleitung 15 mit einer Vakuumleitung 16 verbunden. Ein Teil des Stahlbandes 1 ist abschließend auf einer Speicherrolle 14 in Pfeilrichtung 17 aufgewickelt. Der Abstand vom Stapel 8 zur Speicherrolle 14 wird mittels einer schienenförmigen Auslegevorrichtung 18 überbrückt.Arranged below the guide roller 4 is a stack 8 of sheet pieces or folded products which is height-adjustable in a known manner and to which stationary stop tongues 10, 11 are assigned on the side facing away from the transport direction 9 of the steel strip 1. On both sides of the guide roller 4, as can be seen better in FIG. 3, a suction head 12, 13 is fixed in each case. The suction heads 12, 13 are each connected to a vacuum line 16 via a nozzle line 15. A part of the steel strip 1 is finally wound on a storage roll 14 in the direction of arrow 17. The distance from the stack 8 to the storage roll 14 is bridged by means of a rail-shaped delivery device 18.

Wie in Fig. 2 und 3 zu sehen ist, üben die Zunge 5 eine Greiferfunktion aus. Es öffnen sich die Zungen 5, wenn sie um eine Krümmung, also um die Führungsrolle 4 in Drehrichtung 6 geführt werden und zwar so weit, daß sie ein Bogenstück oder Falzprodukt 19 erfassen können. Um die Bogenaufnahme zu erleichtern, wird jeweils das oberste Bogenstück oder Falzprodukt 19 des Stapels 8 mittels der Sauggköpfe 12, 13 angesaugt und damit örtlich angehoben. Die taktmäßig ankommenden Zungen 5 können somit leicht unter den Rand eines Bogenstückes oder Falzproduktes 19 gleiten. Nachdem die Zungen 5 um die Führungsrolle 4 herumgeführt sind und wieder linear laufen, schließen sich die Zungen 5 greiferartig und klemmen dadurch die aufgenommenen Bogenstücke oder Falzprodukte 19 zwischen sich und dem Stahlband 1 fest. Die Bogenstücke 19 werden beim Weitertransport in Richtung 9 mitgenommen und gleichzeitig von den Saugköpfen 12, 13 abgezogen, so daß das nächste Bogenstück oder Falzprodukt 19 vom Stapel 8 angehoben werden kann. Der Stapel 8 wird dabei in Pfeilrichtung 20 durch einen hier nicht näher gezeigten Antrieb dem Stahlband 1 gleichmäßig zugeführt. Nach Überquerung der schienenförmigen Auslegevorrichtung 18 kann das Stahlband 1 mit den in den Zungen gehaltenen Bogenstücken 19 zu einem Wickel, d.h. zu einer Speicherrolle 14 geformt werden. Wird der beschriebene Vorgang in seiner Laufrichtung (entgegen den Richtungspfeilen 17, 9, 6, 3) umgekehrt, können die in der Speicherrolle 14 abgelegten Bogenstücke 19 wieder entnommen und abgestapelt werden. Die im Bereich der vorderen Stapelkante angeordneten Anschlagzungen 10, 11 sind dafür vorgesehen, die ankommende Kante der abzulegenden Bogenstücke 19 auszurichten.As can be seen in FIGS. 2 and 3, the tongue 5 exerts a gripper function. The tongues 5 open when they are one Curvature, that is to say guided around the guide roller 4 in the direction of rotation 6, to such an extent that it can grip a piece of sheet or folded product 19. In order to facilitate sheet picking up, the uppermost sheet piece or folded product 19 of the stack 8 is sucked in by means of the suction heads 12, 13 and thus locally raised. The tongues 5 arriving at intervals can thus slide easily under the edge of a sheet piece or folded product 19. After the tongues 5 are guided around the guide roller 4 and run again linearly, the tongues 5 close like a gripper and thereby clamp the sheet pieces or folded products 19 received between them and the steel strip 1. The sheet pieces 19 are taken along in the direction of 9 and at the same time removed from the suction heads 12, 13, so that the next sheet piece or folded product 19 can be lifted from the stack 8. The stack 8 is fed evenly in the direction of arrow 20 by a drive, not shown here, to the steel strip 1. After crossing the rail-shaped laying device 18, the steel strip 1 with the arc pieces 19 held in the tongues can be formed into a coil, ie into a storage roll 14. If the process described is reversed in its running direction (contrary to the directional arrows 17, 9, 6, 3), the sheet pieces 19 stored in the storage roll 14 can be removed again and stacked. The stop tongues 10, 11 arranged in the region of the front stacking edge are intended to align the incoming edge of the sheet pieces 19 to be deposited.

Die vorangehenden Ausführungen zeigen, wie in vorteilhafter Weise Bogenstücke oder Falzprodukte 19 übernommen, gespeichert und zwecks der Weiterverarbeitung wieder abgegeben werden können. Die Fig. 5 und 6 zeigen diesbezüglich ein weiteres Ausführungsbeispiel.The preceding explanations show how sheet pieces or folded products 19 can be advantageously taken over, stored and released again for further processing. 5 and 6 show another embodiment in this regard.

Ein Stahlband 21 mit erfindungsgemäßen Zungen 22 wird in der Weise über eine Führungsrolle 23 gekrümmt, daß die Öffnungen der Zungen 22 entgegen der Zugrichtung 24 des analog dem ersten Ausführungsbeispiel von einer Vorratsrolle abgezogen Stahlbandes 21 weisen. Unterhalb der Führungsrolle 23 ist eine Auslegevorrichtung 25, die ortsfeste Führungsbleche 26 und zur Führungsrolle 23 an- bzw. abschwenkbare Zungen 27 aufweist. Die Zungen 27 sind mit einer Druckfeder 28 und an ihrem vom Drehpunkt 29 entfernten Ende mit einer fest montierten Tastrolle 30 versehen. Mittels Bandleitungen 31, 32 werden der Auslegevorrichtung 25 Druckprodukte wie z.B. Falzprodukte 33 in Schuppenform zugeführt. Da die Umlaufgeschwindigkeit der Führungsrolle 23 kleiner als die mittels der Bandleitungen 31, 32 erzeugten Zuführgeschwindigkeit der Falzprodukte 33 ist, werden somit die vorauslaufenden Falzkanten der Falzprodukte 33 taktmäßig in die Öffnungen der Zungen 22, also zwischen sie und dem Stahlband 21 geschoben und bei anschließender Linearführung des Stahlbandes 21 in Pfeilrichtung 35 von den Zungen 22 festgeklemmt. Die schwenkbaren Zungen 27 sind in ihrer Form der Oberfläche der Führungsrolle 23 nachgeformt, um das Einschieben der Falzprodukte 33 in die Zungenöffnungen zu erleichtern und wirken mit der Tastrolle 30, die die Schuppenstromdicke auf der Führungsrolle 23 abtastet, in der Weise zusammen, daß bei zunehmender Verdickung des Schuppenstroms 34 die Zungen 27 stufenweise gegen die Druckfeder 28 von der Führungsrolle 23 weggeschwenkt werden, bis ihre Unterkante parallel zu den Führungsblechen 26 zum Liegen kommt und bei abnehmender Dicke des Schuppenstroms 34 zur Führungsrolle 23 hin geschwenkt werden, so daß die Zungen 27 den Falzprodukten 33 immer genügend Raum lassen, aber dennoch so an den Falzprodukten 33 anliegen, daß sie leicht in die Öffnungen der Zungen 22 geschoben werden können. Anschließend können die Falzprodukte analog dem ersten Ausführungsbeispiel auf eine Speicherrolle gewickelt werden.A steel strip 21 with tongues 22 according to the invention is curved over a guide roller 23 in such a way that the openings of the tongues 22 point counter to the pulling direction 24 of the steel strip 21 drawn off from a supply roll analogously to the first exemplary embodiment. Below the guide roller 23 is a delivery device 25, which is stationary Guide plates 26 and tongues 27 pivotable on and off to guide roller 23. The tongues 27 are provided with a compression spring 28 and at their end remote from the pivot point 29 with a fixedly mounted sensing roller 30. By means of ribbon lines 31, 32, the delivery device 25 is supplied with printed products such as folded products 33 in the form of scales. Since the rotational speed of the guide roller 23 is lower than the feed speed of the folded products 33 generated by means of the band lines 31, 32, the leading fold edges of the folded products 33 are thus pushed into the openings of the tongues 22, i.e. between them and the steel band 21, and with subsequent linear guidance of the steel strip 21 clamped in the direction of arrow 35 by the tongues 22. The pivotable tongues 27 are reshaped in their shape to the surface of the guide roller 23 to facilitate the insertion of the folded products 33 into the tongue openings and interact with the sensing roller 30, which scans the scale flow thickness on the guide roller 23, in such a way that with increasing Thickening of the shingled stream 34, the tongues 27 are gradually pivoted away from the guide roller 23 against the compression spring 28 until their lower edge comes to lie parallel to the guide plates 26 and, as the thickness of the shingled stream 34 decreases, are pivoted towards the guide roller 23, so that the tongues 27 den Folded products 33 always leave enough space, but still rest against the folded products 33 in such a way that they can easily be pushed into the openings of the tongues 22. The folded products can then be wound onto a storage roll analogously to the first exemplary embodiment.
