Description

Die Erfindung betrifft eine Vorrichtung zum Schneiden und Heften von mehrlagigen Druckprodukten in Falzapparaten entsprechend dem Oberbegriff des Patentanspruches 1.The invention relates to a device for cutting and stapling multilayer printed products in folders according to the preamble of claim 1.

Entsprechend der DE 29 32 757 C2 ist eine Heftvorrichtung für Druckmaschinen bekannt, welche mit einem Schneidzylinder kombiniert ist; nachfolgend insgesamt als Heftzylinder bezeichnet.
Innerhalb des Heftzylinders sind Gelenkvierecke mit Greifeinrichtungen angeordnet, die aus der Peripherie des Heftzylinders heraustreten, um die von einer Schneidvorrichtung zuvor mit einer gewünschten Länge abgeschnittenen Drahtstücke zu übernehmen. Im Verlaufe der weiteren Drehbewegung des Heftzylinders führt eine als Patrize wirkende Zunge eine schnelle Abwärtsbewegung in Richtung Zylinderinneres aus, wobei als Matrize eine Platte dient. Die so gebildeten Heftklammern werden nach erfolgter Weiterbewegung zur Peripherie des Heftzylinders gebracht, durch das Produkt gedrückt und gegen den Sammelzylinder als Widerlager geschlossen.According to DE 29 32 757 C2, a stapling device for printing presses is known, which is combined with a cutting cylinder; hereinafter referred to collectively as the stitching cylinder.
Quadrilateral joints with gripping devices are arranged within the stapling cylinder and emerge from the periphery of the stapling cylinder in order to take over the wire pieces previously cut to a desired length by a cutting device. In the course of the further rotary movement of the stapling cylinder, a tongue acting as a male part performs a rapid downward movement in the direction of the cylinder interior, a plate serving as the female part. The staples thus formed are brought to the periphery of the stapling cylinder after further movement, pressed through the product and closed against the collecting cylinder as an abutment.

Nachteilig an dieser Vorrichtung ist, daß zum Entnehmen der Drahtstücke aus der Drahtschneideeinrichtung, Zungen oder Greifer vom Heftzylinder aus betätigt werden müssen, die außerhalb der Peripherie des Heftzylinders wirksam werden, da zwischen Drahtzuführteinrichtung und Klammerbildner ein Abstand gegeben sein muß für den Hüllkreis der ebenfalls umlaufenden Messer. Durch die dabei auftretenden Zentrifugalkräfte der Greifereinrichtungen kann mit dem Heftzylinder nur eine begrenzte Drehzahl gefahren werden.The disadvantage of this device is that for removing the wire pieces from the wire cutting device, tongues or grippers must be actuated from the stapling cylinder, which take effect outside the periphery of the stapling cylinder, since there must be a distance between the wire feed device and the staple former for the enveloping circle of the rotating knives. Due to the centrifugal forces of the gripper devices that occur, only a limited speed can be driven with the stapling cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine rotierende Vorrichtung zum Schneiden und Heften von mehrlagigen Druckprodukten zu schaffen, bei welcher die Matrize der Schneidvorrichtung starr angeordnet ist.The invention has for its object to provide a rotating device for cutting and stapling multilayer printed products, in which the die of the cutting device is rigidly arranged.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils der Patentansprüche 1 und 6 gelöst.This object is achieved by the features of the characterizing part of claims 1 and 6.

Bei der Benutzung der Erfindung entstehen folgende Vorteile. Durch die erfindungsgemäße Vorrichtung ist gesichert, daß keine Teile des Heftzylinders an der Peripherie desselben austreten und trotzdem feststehende Messer am Umfang des Heftzylinders angeordnet sind und mit dem Zylinder umlaufen, ohne daß die Messer Berührung haben mit den Drahtzuführungseinrichtungen.The following advantages arise when using the invention. The device according to the invention ensures that no parts of the stapling cylinder emerge on the periphery of the same and still fixed knives are arranged on the circumference of the stapling cylinder and circulate with the cylinder without the knives coming into contact with the wire feed devices.

In Seitengestellen 1; 2 ist mittels Lager 3; 4 eine Welle 6 unmittelbar gelagert, auf welcher ein quaderförmiger Grundkörper 7 so befestigt ist, daß die Welle 6 rotationssymetrisch den Grundkörper 7 in Längsrichtung aufnimmt. Die Welle 6 mit dem Grundkörper 7 kann einstückig ausgebildet sein. In achsparalleler Richtung sind an den Außenflächen des Grundkörpers 7 Messerbalken 8; 9 aufgenommen, welche Messer 11; 12 tragen, deren Schneidkanten 13; 14 einen Hüllkreis 16 beschreiben mit einem Durchmesser a, welcher durch eine Roationsachse 17 der Welle 6 verläuft. Der Antrieb des Grundkörpers 7 mit dem Messerbalken 8; 9 erfolgt außerhalb des Maschinengestells und jenseits des Seitengestells 1 über ein Zahnrad 18, welches mit dem Antrieb eines Punktur- und Falzmesserzylinders 19 in Verbindung steht. An Stelle von Punkturen können auch Greifer eingesetzt werden. An den inneren Seitengestellen 1; 2 des Maschinengestells sind mittels angedeuteter Schrauben 21 rohrförmige Lagerhalter 22; 23 befestigt, in welchen über Lager 24; 26, vorzugsweise als Dünnringlager ausgeführte Schrägnadellager, hohlzylinderförmige Tragkörper 27; 28 aufgenommen werden. Die Tragkörper 27; 28 sind über zwei sich in achsparalleler Richtung erstreckende und rotationssymetrisch angeordnete, sich gegenüberliegende Tragprofile 29; 30 miteinander verbunden. An dem Tragprofil 29 sind bekannte Heftköpfe 32; 33 und an dem Tragprofil 30 sind ebenfalls bekannte Heftköpfe 34; 35 zum Bilden von Drahtklammern 36; 37 angebracht. Die Einrichtung zum Heften ist in den Seitengestellen 1; 2 gelagert. Die Heftköpfe 32 und 33 arbeiten jeweils mit gestellfesten und jeweils separat angeordneten Drahtzuführungseinrichtungen für Heftdraht zusammen, von denen jedoch nur eine Drahtzuführeinrichtung 38 in Fig. 2 dargestellt ist. Der Antrieb der durch die Tragprofile 29; 30 verbundenen Tragkörper 27; 28 erfolgt über ein Zahnrad 39, welches mittels Schrauben 21 an einer freien Stirnseite des Tragköpers 27 und außerhalb des Lagerhalters 22 angebracht ist. Der Antrieb des Zahnrades 39 erfolgt über einen Antrieb des nichtdargestellten Falzmesserrades.In side frames 1; 2 is by means of bearing 3; 4 a shaft 6 is mounted directly on which a cuboid base 7 is fastened so that the shaft 6 receives the base 7 in a longitudinally symmetrical manner. The shaft 6 with the base body 7 can be formed in one piece. In the direction parallel to the axis, 7 cutter bars 8; 9 added, which knife 11; 12 wear, the cutting edges 13; 14 describe an enveloping circle 16 with a diameter a, which runs through a rotation axis 17 of the shaft 6. The drive of the base body 7 with the cutter bar 8; 9 takes place outside the machine frame and beyond the side frame 1 via a gear wheel 18, which is connected to the drive of a puncturing and folding knife cylinder 19. Instead of punctures, grippers can also be used. On the inner side frames 1; 2 of the machine frame are tubular bearing holders 22; 23 attached in which via bearings 24; 26, preferably designed as a thin ring bearing inclined needle bearing, hollow cylindrical support body 27; 28 are included. The support body 27; 28 are over two extending in the axially parallel direction and rotationally symmetrically arranged, opposite support profiles 29; 30 connected to each other. Known stitching heads 32; 33 and on the support profile 30 are also known stitching heads 34; 35 for forming wire clips 36; 37 attached. The device for stapling is in the side frames 1; 2 stored. The stitching heads 32 and 33 each work together with wire feed devices for stitching wire which are fixed to the frame and are arranged separately, of which only one wire feed device 38 is shown in FIG. 2. The drive of the through the support profiles 29; 30 connected support body 27; 28 takes place via a gear 39, which is attached by means of screws 21 to a free end face of the support body 27 and outside of the bearing holder 22. The gear 39 is driven by a drive of the folding knife wheel, not shown.

Die Lagerhalter 22; 23 sind so an den Seitengestellen 1; 2 des Maschinengestells angebracht, daß eine Rotationsachse 41 der die Hefteinrichtungen 32 bis 35 tragenden Tragprofile 29; 30 in einem Abstand b zur Rotationsachse 17 der Welle 6 angeordnet ist. Der Durchmesser c eines Hüllkreises 42, den die Heftköpfe 32 bis 35 beim Umlaufen beschreiben, reicht bis an die noch darzustellende Organe der Drahtzuführeinrichtungen 38 heran.The bearing holder 22; 23 are so on the side frames 1; 2 of the machine frame attached that a rotational axis 41 of the support profiles 29; 30 is arranged at a distance b from the axis of rotation 17 of the shaft 6. The diameter c of an enveloping circle 42, which the stitching heads 32 to 35 describe when rotating, extends as far as the organs of the wire feed devices 38 which are still to be shown.

Der Antrieb der Schneid- und Heftvorrichtung über die Zahnräder 18; 39 erfolgt in der Art, daß die Heftköpfe 32 bis 35 sowie die Schneidkanten 13; 14 der sich über die gesamte Bahnbreite d erstreckenden Messer 11; 12 stets auf dasselbe auf dem Punktur- und Falzmesserzylinder 19 befindliche Gegenlager treffen.
In Fig. 2 ist die Schneidestellung eines in Pfeilrichtung E einlaufenden, jedoch nichtdargestellten Produktes zwischen der Schneidkante 13 des Messers 11 und einer am Umfang des Punktur- und Schneidmesserzylinders 19 angeordneten Schneidleiste 43 gezeigt.
Die Funktionsweise der erfindungsgemäßen Vorrichtung ist wie nachfolgend beschrieben.The drive of the cutting and stapling device via the gears 18; 39 is done in such a way that the stitching heads 32 to 35 and the cutting edges 13; 14 of the knives 11; 12 always hit the same counter bearing located on the puncture and folding knife cylinder 19.
FIG. 2 shows the cutting position of a product which is entering the direction of arrow E but is not shown, between the cutting edge 13 of the knife 11 and a cutting bar 43 arranged on the circumference of the puncturing and cutting knife cylinder 19.
The operation of the device according to the invention is as described below.

Den Heftköpfen 32; 33 werden, wie in Fig. 1 symbolisch gezeigt, Draht von nichtdargestellten Drahtrollen über Transportrollenpaare 47; 48 zugeführt (siehe dazu auch DE-PS 11 89 562). Die Heftköpfe 32 bis 35 weisen jeweils einen festangeordneten Stempel 49 bis 52 auf. Neben den Stempeln 49 bis 52 sind beidseitig Führungen 54 bis 61 angeordnet, die mit Heftkolben 63 bis 66 verbunden sind. Die Führungen 54 bis 61 sind jeweils mit den Stempeln 49 bis 52 in radialer Richtung bewegbar. Nachdem der Draht 44; 46 mittels der Transportrollenpaare 47; 48 über die Führungen 54 bis 57 gefördert worden ist (Drahteinlauf- und Drahtschneidedüsen in einem Steckbolzen angeordnet, sind nicht dargestellt) kommen Biegerollen zum Einsatz, in Fig. 2 einmal dargestellt und mit 68 bezeichnet, die den zugeführten Draht 44; 46 zu Heftklammern 36; 37 formen. Dabei drückt die Biegerolle 68 den auf den Führungen 54 bis 57 liegenden Draht 44; 46 zwischen den Führungen 54 bis 57 bis zu den Stempeln 49; 50 herunter, so daß Klammern 36; 37 geformt werden. Die Führunyen 54 bis 61 weisen dazu noch in radialer Richtung verlaufende Längsnuten auf. Beim Weiterdrehen der erfindungsgemäßen Vorrichtung in Pfeilrichtung F kommen die Klammern 36; 37 mit ihren nach oben weisenden offenen Schenkeln in Eingriff mit in Drehrichtung F verlaufenden gestellfesten Führungszungen; in Fig. 2 einmal dargestellt und mit 69 bezeichnet, welche zwischen den Schenkeln der Klammern 36; 37 verlaufen und die Klammern 36; 37 vor der Wirkung der Zentrifugalkräfte bewahren. Nach Berührung der Schenkelenden der Klammern 36; 37 mit dem zu heftenden Produkt und geringfügigem Einstechen in dasselbe, besitzen die Klammern 36; 37 bereits einen Halt in dem Produkt. Zu diesem Zeitpunkt werden die auf den Heftkolben 63; 64 angeordneten Führungen 54 bis 57 durch eine Bewegung einer Steuerspindel 70; 77 in radialer Richtung D zurückgezogen, damit keine Berührung dieser klammerbildenden Organe mit dem Produkt erfolgt.
Diese radiale Bewegung wird über Führungsrollen 72; 73 bewirkt, die in einer gestellfesten Steuerkurve 75 laufen. Die Hebelarme 76; 77 der Führungsrollen 72; 73 werden durch nichtdargestellte Rückstellfedern an die Steuerkurve 75 angedrückt. Nach erfolgtem Weiterdrehen der Vorrichtung in Drehrichtung F und Durchstechen der Klammern 36; 37 durch das Produkt wird durch ein entsprechendes Widerlager 78 auf dem Punktur- und Falzmesserzylinder 19 die Klammerschließung vollzogen infolge Umwalzens der Schenkel der Klammern 36; 37 zueinander. Die sich weiter in Drehrichtung F auf die Drahtzuführungseinrichtungen 38 zu bewegende Schneidkante 14 des Messers 12 taucht infolge des Abstandes b beider Rotationsachsen 17; 41 zueinander unter den Drahtzuführungseinrichtungen 38 ab, so daß keine Berührung der Messerschneide 14 sowie der in Drehrichtung F nachfolgenden Messerschneide 13 mit den Drahtzuführungseinrichtungen 38 erfolgt. Die zwei anderen am Umfang der Vorrichtung angebrachten Heftköpfe 34; 35 können wahlweise bei Sammelbetrieb abgestellt werden. Es ist auch möglich, bei einer Verdrehung der Heftvorrichtung zur Schneidvorrichtung je nach Drehrichtung einen Überfalz oder Unterfalz herzustellen. Voraussetzung dafür ist auch eine entsprechende Nachjustierung der Falzmesserabstände auf dem Punktur- und Falzmesserzylinder 19. Weiterhin ist es möglich, abweichend vom gezeigten Ausführungsbeispiel, jeweils drei Einrichtungen zum Schneiden und Heften in der erfindungsgemäßen Vorrichtung anzuordnen.The stitching heads 32; 33, as shown symbolically in FIG. 1, wire from wire rolls (not shown) via pairs of transport rolls 47; 48 supplied (see also DE-PS 11 89 562). The stitching heads 32 to 35 each have a fixed stamp 49 to 52. In addition to the stamps 49 to 52, guides 54 to 61 are arranged on both sides, which are connected to staples 63 to 66. The guides 54 to 61 are movable with the punches 49 to 52 in the radial direction. After the wire 44; 46 by means of the pairs of transport rollers 47; 48 has been conveyed via the guides 54 to 57 (wire inlet and wire cutting nozzles arranged in a plug pin, are not shown), bending rollers are used, shown once in FIG. 2 and denoted by 68, which the supplied wire 44; 46 to staples 36; 37 shapes. The bending roller 68 presses the wire 44 lying on the guides 54 to 57; 46 between the Guides 54 to 57 up to the stamps 49; 50 down so that brackets 36; 37 are formed. The guides 54 to 61 also have longitudinal grooves running in the radial direction. When the device according to the invention is turned further in the direction of arrow F, the clamps 36; 37 with their upwardly facing open legs in engagement with frame-fixed guide tongues running in the direction of rotation F; shown once in Figure 2 and designated 69, which between the legs of the brackets 36; 37 run and the brackets 36; 37 Protect from the effects of centrifugal forces. After touching the leg ends of the clips 36; 37 with the product to be stapled and slightly stabbed into it, the clips 36; 37 already a stop in the product. At this time, the on the plunger 63; 64 arranged guides 54 to 57 by movement of a control spindle 70; 77 retracted in the radial direction D so that these clamp-forming organs do not come into contact with the product.
This radial movement is carried out via guide rollers 72; 73 causes that run in a control cam 75 fixed to the frame. The lever arms 76; 77 of the guide rollers 72; 73 are pressed against the cam 75 by return springs (not shown). After the device has continued to rotate in the direction of rotation F and pierced the clamps 36; 37 by the product, the clamp is closed by a corresponding abutment 78 on the puncture and folding knife cylinder 19 as a result of the legs of the clamps 36 being rolled over; 37 to each other. Which continues in the direction of rotation F on the Wire feed devices 38 to be moved cutting edge 14 of the knife 12 dips due to the distance b between the two axes of rotation 17; 41 from each other under the wire feed devices 38, so that there is no contact between the knife edge 14 and the knife edge 13 following in the direction of rotation F with the wire feed devices 38. The two other stitching heads 34; 35 can optionally be parked in collective operation. It is also possible to produce an overlap or underlap when the stapling device is rotated relative to the cutting device, depending on the direction of rotation. A prerequisite for this is a corresponding readjustment of the folding knife spacing on the puncturing and folding knife cylinder 19. Furthermore, in deviation from the exemplary embodiment shown, it is possible to arrange three devices for cutting and stapling in the device according to the invention.

Der Abstand der beiden Rotationsachsen 17; 41 bzw. die Exzentrizität b liegt zweckmäßigerweise zwischen 10 und 50 mm. Die Schnittdarstellung II - II in Fig. 2 ist gegenüber der Darstellung um ca. 20o im Uhrzeigersinn verdreht.The distance between the two axes of rotation 17; 41 or the eccentricity b is expediently between 10 and 50 mm. The sectional view II - II in Fig. 2 is rotated by about 20 o clockwise compared to the representation.

Zur Lage beider Rotationsachsen 17; 41 zueinander wird präzisiert, daß die Vorrichtung zum Schneiden 8; 9; 11 bis 14, bezogen auf ein rechtwinkliges Koordinatensystem mit dem Ursprung auf der Rotationsachse 41 der Vorrichtung zum Heften 29 bis 35 im III. Quadranten des Koordinatensystems liegt, wenn der Papiereinlauf E im II. Quadranten erfolgt bei einer Drehrichtung der Vorrichtung zum Schneiden und Heften 8, 9, 11 bis 14 und 29 bis 35 entgegen dem Uhrzeigersinn. Ebenso kann aber auch die Rotationsachse 17 der Vorrichtung zum Schneiden 8, 9, 11 bis 14, bezogen auf das Koordinatensystem mit dem Ursprung auf der Rotationsachse 41 der Einrichtung zum Heften 29 bis 35 im IV. Quadranten liegen, wenn der Papiereinlauf E im I. Quadranten erfolgt bei einer Drehrichtung der Vorrichtung zum Schneiden und Heften 8, 9, 11 bis 14 und 29 bis 35 im Uhrzeigersinn.The location of both axes of rotation 17; 41 to each other is specified that the device for cutting 8; 9; 11 to 14, based on a rectangular coordinate system with the origin on the axis of rotation 41 of the Device for stapling 29 to 35 in III.
