Definitions
- the invention relates to a device for opening and for spreading folded products fed via a ribbon line with a device for introducing separating elements in each case into the loop-shaped area of the not fully folded fold back.
- a folding and transport device is known from EP 0 250 758 A1, in which the fold does not extend completely over the length or width of the copy to be folded, so that a loop is formed on one side of the folded products, into which of tongues can be inserted from the side so that the products can be opened again without overlap.
- the object of the invention is to provide a device with which folded products transported in the form of scales are opened, i.e. are spread in order to be able to feed them in a spread form to a subsequent transport or storage system, for example a moving zigzag structure.
- the ability to spread shingled folded products means that more time is available for the individual work processes because the speed of the folded products is lower than at an unbalanced product feed.
- the shingled stream can be taken directly from a folder.
- Particular advantages of the invention lie in the fact that the grippers provided in groups by an opening cylinder cause the folded product to spread even during a partial rotation of the opening cylinder, since several grippers can be inserted into the folded products in a short time starting from the fold back by corresponding lateral control of the displacement of the grippers are, with the spread delivery in the same order, the grippers are pulled out again, ie that the rearmost gripper holds a folded product or half of a folded product relatively long on the opening cylinder. The spreading takes place in the smallest space, since a compact cylinder is used instead of relatively long or voluminous bands.
- Fig. 1 shows how when folding the folded product or sheet 1 in a known manner in a folder (not specified) with the help of jaws 2 or 3 of a jaw cylinder 4 and a folder 5 of a folder cylinder 6 two sheet halves 7 and 8 are formed .
- the sheet 1 is preferably not completely folded through, so that a loop 101 is formed on the side of the sheet, as described in detail in EU-PS 0 250 758.
- care must be taken to ensure that this loop 101 remains laterally outside the transport devices so that it is not compressed.
- the roller 1 is braked in stages in a known manner by roller pairs 9 and 10 or 11 and 12 and by means of ribbon lines 13 and 14, as the positions 1 ', 1''and1''' of the roller 1 show in succession.
- position 1 '''the folded sheets 1 are thus in a scale formation.
- This formation of scales is supported in a novel, advantageous manner by a chain 16 which rotates in a clockwise manner in the direction of arrow 15, the bars 17 of which on the one hand penetrate through the gap between the arches in positions 1 'and 1''and on the other hand in arch position 1''' at the end of the arch lift so that the following arches for forming the scale can be pushed under the leading ones (under-scaling).
- Fig. 2 shows this process in an enlarged section.
- the folded sheets 1 now come in scaled form on a sliding plate 18.
- the following gripper cylinder 100 according to the invention is described in detail below.
- the axis 19 of the gripper cylinder 100 is cyclically driven by a driver chain 20 with drivers 21 via the chain wheel 22, the shaft 23 and spur gears 24 and 25 in the direction of arrow 26.
- the drive chain 20 moves in the direction 27.
- the axis 19 is supported in supports 28 and 29. 30, 31 and 32 discs 33, 34 and 35 are fastened on it with the aid of clamping pieces.
- a number of axially movable plungers 36 and 37 are mounted, on which tongues or grippers 38, 39, 40 and 41 are seated.
- these grippers 38 to 41 each lie as a group of four in a spiral to the center of the gripper cylinder 100 (FIG. 4) and thus follow the course of the arches 1 lying in a scale-like manner around the cylinder.
- FIG 42 and 43 and clamped holders 44 and 45 pressed against axial cams 46 and 47.
- the holder 44 and 45 are guided by slotted pins 48 and thereby secure the plunger 36, 37 against rotation (Fig. 6).
- the axial cams 46 and 47 are rotatably supported on the axis 19 by means of a cam carrier 49 and are supported by a torque arm 50 (FIGS. 3, 5 and 8).
- a torque arm 50 (FIGS. 3, 5 and 8).
- the plungers 36, 37 and thus the grippers 38 to 41 are axially moved back and forth when the axial cam disks 46, 47 are stationary.
- rings 51, 52, 53 with preferably angular stops 54, 55 and 56 on the periphery of the disks 33, 34 and 35 for receiving the folded edges of the folded sheets 1, thereby aligning them.
- the loops 101 open.
- the other three grippers 39, 40 and 41 related to the sheet 1 can penetrate one after the other, each gripper opening the sheet virtually to the other. Together, they clamp or hold the sheet half 8 of the sheet 1 firmly on the gripper cylinder 100.
- the sheets 1 are also held on the circumference of the cylinder by the ribbon cable 58.
- position 38 ′′ (FIG. 4)
- the first of the four sheet-related grippers 38 to 41 releases the sheet half 8.
- the sheet 1 is deflected by fixed tongues 59 and 60 so that it detaches from the stops 54, 55 and 56.
- the opening of the sheet halves 7 and 8 shown in FIG. 4 results when penetrating into the zigzag structure 75.
- This structure moves due to the entrainment the driver chains 20 and 61 with the drivers 21 in the direction of arrow 62.
- the opposite direction of rotation 26 of the gripper cylinder 100 accelerates the penetration of the sheets 1 into the zigzag structure 75 (FIG. 4).
- This zigzag structure 75 for receiving folded sheets 1 is described in detail as a transport and storage structure in the patent specification DE 36 21 832, the two-part embodiment also shown there being used.
- deflected in the direction of arrow 63 (FIG. 7)
- it is able to penetrate between the bow halves 7 and 8 with its tongues 64 and 65 on one side of the bow 1, namely the open one (FIG. 4).
- this opening is pulled to the other side by the rotation of the screw 66 in the direction of arrow 67, whereupon the structure 75 is able to here also by a deflection in the direction 68 with their tongues 64, 65 to penetrate between the bow halves 7, 8.
- This process is also described in detail in DE 36 21 822.
- a worm 66 is cyclically driven by the drive chain 61 via a sprocket 69, a shaft 70, bevel gears 71, 72, a shaft 73 and a toothed belt 74.

Description
Die Erfindung betrifft eine Vorrichtung zum Öffnen und zum gespreizten Obergeben von über eine Bandleitung zugeführten Falzprodukten mit einer Einrichtung zum Einführen von Trennelementen jeweils in den schlaufenförmigen Bereich des nicht vollständig durchgefalzten Falzrückens.The invention relates to a device for opening and for spreading folded products fed via a ribbon line with a device for introducing separating elements in each case into the loop-shaped area of the not fully folded fold back.
Aus der EP 0 250 758 A1 ist eine Falz- und Transportvorrichtung bekannt, bei der der Falz sich nicht vollständig über die Länge bzw. Breite des zu falzenden Exemplares erstreckt, so daß sich an einer Seite der Falzprodukte jeweils eine Schlaufe bildet, in die von der Seite her Zungen einführbar sind, um die Produkte ohne Überfalz wieder öffnen zu können. Mit den aus dieser Schrift bekannten Mitteln ist es jedoch nicht möglich, geschuppte, beispielsweise auf einer Bandleitung ankommende Falzexemplare zu öffnen und in gespreizter Form einem nachgeordneten Transport- oder Speichersystem, beispielsweise einer Zick-Zackstruktur, zuzuleiten.A folding and transport device is known from EP 0 250 758 A1, in which the fold does not extend completely over the length or width of the copy to be folded, so that a loop is formed on one side of the folded products, into which of tongues can be inserted from the side so that the products can be opened again without overlap. With the means known from this document, however, it is not possible to open shingled, for example arriving on a ribbon line, and to spread them in a spread form to a downstream transport or storage system, for example a zigzag structure.
Des weiteren ist es auch aus der EP 0 169 490 A1 bekannt, mit Hilfe eines Öffnungszylinders gefalzte Bogen oder Bogenpakete am vorauslaufenden Falzrücken durch Vorgreifer aufzunehmen, um anschließend mit Hilfe von Rückgreifern den Überfalz zu erfassen und den Bogen mit Hilfe von Fliehkräften zu öffnen. Nachteilig ist es hierbei jedoch, daß infolge des benötigten Überfalzes für den Öffnungsvorgang ein erhöhter Papierverbrauch auftritt. Letztlich ist in der deutschen Patentschrift 36 21 822 eine Transportvorrichtung für Falzprodukte beschrieben, zu der parallel ein Riemen oder eine Kette läuft, an der seitlich in den Falzbogen vor dem Falzklappenzylinder eintauchende Finger vorgesehen sind, die an der Falzproduktübernahmestelle durch einen von der relativ langen Transportvorrichtung wegführenden Weg das Falzprodukt einseitig öffnet. Auch mit dieser Vorrichtung ist es nicht möglich, schuppenförmig transportierte Falzprodukte zu spreizen und in gespreizter Form einem nachfolgenden System zuzuführen.Furthermore, it is also known from EP 0 169 490 A1 to pick up folded sheets or bundles of sheets on the leading fold back by means of pre-grippers with the aid of an opening cylinder, in order then to grasp the overlap with the aid of pullers and to open the sheet with the aid of centrifugal forces. However, it is disadvantageous that increased paper consumption occurs due to the overlap required for the opening process. Ultimately, a transport device for folded products is described in the
Aufgabe der Erfindung ist die Schaffung einer Vorrichtung, mit der in Schuppenform transportierte Falzprodukte geöffnet, d.h. gespreizt, werden, um diese in gespreizter Form einem nachfolgenden Transport- oder Speichersystem, beispielsweise einer sich bewegenden Zick-Zack-Struktur zuführen zu können.The object of the invention is to provide a device with which folded products transported in the form of scales are opened, i.e. are spread in order to be able to feed them in a spread form to a subsequent transport or storage system, for example a moving zigzag structure.

Durch die Möglichkeit, geschuppt zugeführte Falzprodukte spreizen zu können, steht mehr Zeit für die einzelnen Arbeitsvorgänge zur Verfügung, da die Geschwindigkeit der Falzprodukte niedriger als bei einer ungeschuppten Produktzuführung ist. Der Schuppenstrom kann direkt einem Falzapparat entnommen werden. Besondere Vorteile der Erfindung liegen darin, daß durch die von einem Öffnungszylinder jeweils gruppenweise vorgesehenen Greifer bereits während einer Teilumdrehung des Öffnungszylinders eine Spreizung des Falzproduktes bewirken, da beginnend vom Falzrücken durch entsprechende seitliche Steuerung der Verschiebung der Greifer mehrere Greifer in kurzer Zeit in die Falzprodukte einschiebbar sind, wobei bei der gespreizten Übergabe in der gleichen Reihenfolge die Greifer wieder herausgezogen werden, d.h. daß der hinterste Greifer jeweils ein Falzprodukt bzw. die Hälfte eines Falzproduktes relativ lange am Öffnungszylinder festhält. Die Spreizung erfolgt auf kleinstem Raum, da ein kompakt bauender Zylinder anstelle relativ langer bzw. voluminöser Bänder verwendet wird.The ability to spread shingled folded products means that more time is available for the individual work processes because the speed of the folded products is lower than at an unbalanced product feed. The shingled stream can be taken directly from a folder. Particular advantages of the invention lie in the fact that the grippers provided in groups by an opening cylinder cause the folded product to spread even during a partial rotation of the opening cylinder, since several grippers can be inserted into the folded products in a short time starting from the fold back by corresponding lateral control of the displacement of the grippers are, with the spread delivery in the same order, the grippers are pulled out again, ie that the rearmost gripper holds a folded product or half of a folded product relatively long on the opening cylinder. The spreading takes place in the smallest space, since a compact cylinder is used instead of relatively long or voluminous bands.
Fig. 1 zeigt, wie beim Falzen des Falzproduktes bzw. Bogens 1 in bekannter Weise in einem Falzapparat (nicht näher bezeichnet) mit Hilfe von Falzklappen 2 bzw. 3 eines Falzklappenzylinders 4 und eines Falzmessers 5 eines Falzmesserzylinders 6 zwei Bogenhälften 7 und 8 gebildet werden. Bei diesem Falzvorgang wird der Bogen 1 vorzugsweise nicht ganz durchgefalzt, so daß an der Seite des Bogens eine Schlaufe 101 entsteht, wie in der EU-PS 0 250 758 im einzelnen beschrieben ist. Beim folgenden Transport des Bogens 1 muß darauf geachtet werden, daß diese Schlaufe 101 seitlich außerhalb der Transporteinrichtungen bleibt, so daß sie nicht zusammengedrückt wird. Durch Walzenpaare 9 und 10 bzw. 11 und 12 sowie durch Bandleitungen 13 und 14 wird der Bogen 1 in bekannter Weise in Stufen abgebremst, wie nacheinander die Positionen 1', 1'' und 1''' des Bogens 1 zeigen. In der Position 1''' liegen die Falzbogen 1 dadurch in Schuppenformation vor. Diese Schuppenbildung wird in neuartiger vorteilhafter Weise durch eine taktförmig in Pfeilrichtung 15 umlaufende Kette 16 unterstützt, deren Balken 17 einerseits durch die Lücke zwischen den Bögen in den Positionen 1' und 1'' durchtauchen und sie andererseits in der Bogenposition 1''' am Bogenende anheben, damit die Folgebögen zur Bildung der Schuppe unter die vorlaufenden geschoben werden können (Unterschuppung). Fig. 2 zeigt diesen Vorgang in einem vergrößerten Ausschnitt.Fig. 1 shows how when folding the folded product or
Die Falzbögen 1 kommen nun in geschuppter Form auf ein Gleitblech 18. Der nachfolgende erfindungsgemäße Greiferzylinder 100 wird nachfolgend im einzelnen beschrieben.The folded
Wie aus den Figuren 1, 4 und 5 ersichtlich, wird die Achse 19 des Greiferzylinders 100 taktmäßig von einer Mitnehmerkette 20 mit Mitnehmern 21 über das Kettenrad 22, die Welle 23 sowie Stirnräder 24 und 25 in Pfeilrichtung 26 angetrieben. Die Mitnehmerkette 20 bewegt sich dabei in Richtung 27. Die Achse 19 ist in Stützen 28 und 29 gelagert. Auf ihr sind mit Hilfe von Klemmstücken 30, 31 und 32 Scheiben 33, 34 und 35 befestigt. In den Scheiben 34 und 35 wiederum ist eine Anzahl axial bewegbarer Stößel 36 und 37 gelagert, auf denen Zungen bzw. Greifer 38, 39, 40 und 41 sitzen. Diese Greifer 38 bis 41 liegen erfindungsgemäß jeweils als Vierergruppe spiralförmig zum Zentrum des Greiferzylinders 100 (Fig. 4) und folgen somit dem Verlauf der schuppenförmig um den Zylinder liegenden Bögen 1. Wie Fig. 5 weiter zeigt, werden die Stößel 36, 37 über Druckfedern 42 und 43 und aufgeklemmte Halter 44 und 45 gegen Axialkurvenscheiben 46 und 47 gedrückt. Die Halter 44 und 45 werden dabei von geschlitzten Stiften 48 geführt und sichern dadurch die Stößel 36, 37 gegen Verdrehung (Fig. 6).As can be seen from FIGS. 1, 4 and 5, the
Die Axialkurvenscheiben 46 und 47 sind über einen Kurventräger 49 drehbar auf der Achse 19 gelagert und über eine Drehmomentstütze 50 abgestützt (Fig. 3, 5 und 8). Bei Drehung des Zylinders 100 werden somit bei stillstehenden Axialkurvenscheiben 46, 47 die Stößel 36, 37 und somit die Greifer 38 bis 41 axial hin- und herbewegt. Des weiteren befinden sich am Umfang der Scheiben 33, 34 und 35 Ringe 51, 52, 53 mit daraufsitzenden vorzugsweise winkelförmigen Anschlägen 54, 55 und 56 zur Aufnahme der Falzkanten der Falzbögen 1, wodurch diese ausgerichtet werden. Die Schlaufen 101 öffnen sich dabei.The
Da die Transportgeschwindigkeit der Falzbögen 1 in Richtung 57 (Fig. 3) größer ist als die Umfangsgeschwindigkeit des Greiferzylinders 100 und damit der Anschläge 54, 55 und 56, werden die Bögen 1 fest gegen die Anschläge 54 bis 56 geschoben und dabei exakt ausgerichtet. Die Bandleitung 13 ist dazu sorgfältig eingestellt, damit nicht zuviel, aber auch nicht zu wenig geschoben wird. Durch dieses Aufschieben vergrößert sich auch die Schlaufe 101 im Falzbogen 1, so daß der Greifer 38 in der in Fig. 4 gezeigten Position 38' besser zwischen die Bogenhälften dringen kann. Zudem sind alle Greifer 38 bis 41 gemäß Fig. 9 (eine Ansicht in Pfeilrichtung V der Fig. 5 ) geformt, wodurch das Eindringen, zunächst mit der Spitze 75, ebenfalls erleichtert wird. Nachfolgend können nun bei weiterer Drehung des Greiferzylinders 100 in Pfeilrichtung 26 die übrigen auf den Bogen 1 bezogenen drei Greifer 39, 40 und 41 nacheinander eindringen, wobei jeder Greifer quasi, dem anderen vorlaufend den Bogen öffnet. Gemeinsam klemmen bzw. halten sie die Bogenhälfte 8 des Bogens 1 fest am Greiferzylinder 100. Die Bögen 1 werden außerdem von der Bandleitung 58 am Zylinderumfang gehalten. In der Position 38'' (Fig. 4) gibt der erste der vier bogenbezogenen Greifer 38 bis 41 die Bogenhälfte 8 frei. Der Bogen 1 wird durch feststehende Zungen 59 und 60 ausgelenkt, so daß er sich aus den Anschlägen 54, 55 und 56 löst. Da die Greifer 39, 40 und 41 ebenfalls erst nacheinander die Bogenhälfte 8 freigeben, ergibt sich die in Fig. 4 gezeigte Öffnung der Bogenhälften 7 und 8 beim Eindringen in die Zick-Zack-Struktur 75. Diese Struktur bewegt sich auf Grund der Mitnahme durch die Mitnehmerketten 20 und 61 mit den Mitnehmern 21 in Pfeilrichtung 62. Durch die entgegengesetzte Drehrichtung 26 des Greiferzylinders 100 wird das Eindringen der Bögen 1 in die Zick-Zack-Struktur 75 beschleunigt (Fig. 4).Since the transport speed of the folded
Diese Zick-Zack-Struktur 75 zur Aufnahme von Falzbögen 1 ist als Transport- und Speicherstruktur in der Patentschrift DE 36 21 832 eingehend beschrieben, wobei die dort auch gezeigte zweiteilige Ausführung Verwendung findet. Diese ist in der Lage, bei Auslenkung in Pfeilrichtung 63 (Fig. 7) zunächst auf der einen Seite des Bogens 1, nämlich der geöffneten (Fig. 4) mit ihren Zungen 64 und 65 zwischen die Bogenhälften 7 und 8 einzudringen. Dann wird diese Öffnung durch die Drehung der Schnecke 66 in Pfeilrichtung 67 auf die andere Seite gezogen, worauf die Struktur 75 in der Lage ist, hier ebenfalls durch eine Auslenkung in Richtung 68 mit ihren Zungen 64, 65 zwischen die Bogenhälften 7, 8 einzudringen. Dieser Vorgang ist ebenfalls in der Patentschrift DE 36 21 822 eingehend beschrieben. Auf diese Weise werden die gefalzten Bogen 1 fortlaufend abgespeichert, wonach sie jederzeit durch Auseinanderziehen der Struktur 75 geöffnet und dadurch Beilagen aufnehmen können. Wie in den Fig. 1, 5 und 7 gezeigt, wird eine Schnecke 66 taktmäßig von der Mitnehmerkette 61 über ein Kettenrad 69, eine Welle 70, Kegelräder 71, 72, eine Welle 73 sowie von einem Zahnriemen 74 angetrieben.This
