Description

Die erfindung betrifft eine Vorrichtung zum Herstellen von Verbindungsstellen für übereinanderliegende, stetig transportierte Bahnen, insbesondere Formularbahnen, mittels Klebbandstreifen, welche von der Außenkante aus die Formularbahnen umschließen und durch in der Nähe des Formularrandes befindliche Löcher hindurch zusammengefügt sind oder mittels Heftstreifen, die die Formularbahnen von nahe des Formularbahnrandes befindlichen Löchern aus umschließen und außerhalb der Formularbahnen zusammengefügt sind oder mittels kleiner bügelartiger Laschen, die durch einzelne nahe des Bahnrandes liegende Perforationen greifen und die mit ihren Enden an den Außenflächen der übereinandergelegten Bahnen angeklebt sind. Hierbei sind die Klebbandvorratsrolle, die Zugrolle für den Transport des Klebbandes und Messer zum Abtrennen des Klebbandstreifens bzw. des Laschenmaterials in einem Körper untergebracht, welcher oberhalb der Formularbahnen gelagert ist.The invention relates to a device for producing connection points for superimposed, constantly transported webs, in particular form webs, by means of adhesive tape strips which enclose the form webs from the outer edge and are joined through holes located near the edge of the form or by means of adhesive strips which separate the form webs from enclose holes located near the edge of the form web and are joined together outside of the form web or by means of small bow-like tabs which grip through individual perforations lying near the web edge and whose ends are glued to the outer surfaces of the superimposed webs. The adhesive tape supply roll, the pulling roller for transporting the adhesive tape and knives for separating the adhesive tape strip or the tab material are accommodated in a body which is mounted above the form webs.

Bei den bisher bekannten Vorrichtungen wird das Laschenmaterial durch einen ortsfesten Stempel auf die unter der Vorrichtung hindurchlaufenden Formularbahnen gedrückt und dadurch schlagartig aus dem Stand auf Bahngeschwindigkeit beschleunigt. Die Arbeitsgeschwindigkeit sind Grenzen gesetzt, da bei Steigerung der Bahngeschwindigkeit eine immer größer werdende Differenzgeschwindigkeit zwischen dem Laschenmaterial und den Formularbahnen entsteht, was zu örtlichem Versatz des Laschenmaterials führt. Außerdem muß die Schneideinrichtung zum Abtrennen des Laschenmaterials bei schneller Bahngeschwindigkeit mit sehr hoher Schnittfolge arbeiten. Durch diese Nachteile ist das Leistungsvermögen dieser bekannten Vorrichtungen begrenzt.In the previously known devices, the tab material is pressed onto the form webs passing under the device by a stationary stamp and thereby suddenly accelerated from a standing position to web speed. The working speed is limited, because as the web speed increases, the differential speed between the flap material and the form webs increases, which leads to local misalignment of the flap material. In addition, the cutting device for cutting off the tab material must work at a high web speed with a very high cutting sequence. These disadvantages limit the performance of these known devices.

Die Herstellung von Formularsätzen erfolgt heute in großem Umfang, von Rolle auf Falz, in schnell laufenden Maschinen, sogenannten Rollencollatoren.Form sets are now manufactured on a large scale, from roll to fold, in high-speed machines, so-called roll collators.

Werden die Formularbahnverbindungsstellen nach DE-GM 1 899 831 mit der aus den DE-PS 1 436 814 und 2 205 714 bekannten Vorrichtung in Rollencollatoren hergestellt, kann durch das geringe Leistungsvermögen der bekannten Vorrichtung die an sich hohe mögliche Laufgeschwindigkeit der Rollencollatoren bei weitem nicht ausgenutzt werden.If the form web connection points according to DE-GM 1 899 831 with the device known from DE-PS 1 436 814 and 2 205 714 are manufactured in roller collators, the low performance of the known device means that the high possible running speed of the roller collators can by no means be exploited will.

Durch die Erfindung soll die Aufgabe gelöst werden, eine Vorrichtung anzugeben, mit der Formulare bzw. Formularbahnen schneller und besser als bisher zu Formularsätzen verbunden werden können.The object of the invention is to provide a device with which forms or form webs can be connected faster and better than before to form sets.

Diese Aufgabe wird bei Vorrichtungen der eingangs genannten Art dadurch gelöst, daß der Körper um eine zur Bahnvorschubrichtung quer verfaufende Achse drehbar angeordnet ist und dessen Umfangsgeschwindigkeit auf den äußersten Punkt des gleichzeitig zum Andrücken des Streifens ausgebildeten Messers bezogen zum Zeitpunkt des aufgrund der Messerbewegung erfolgenden Andrückens des Streifens bzw. des Laschenmaterials auf die Formularbahnen gleich Formulargeschwindigkeit ist, oder einem ganzzahligen Bruchteil (1/4, 1/3, 1/2) bzw. einem ganzzahligen Vielfachen (2, 3, 4) der Formulargeschwindigkeit entspricht.This object is achieved in devices of the type mentioned in that the body is rotatably arranged about an axis extending transversely to the web feed direction and its peripheral speed is based on the outermost point of the knife designed simultaneously for pressing the strip at the time of the pressing of the knife due to the knife movement Strip or the flap material on the form webs is the form speed, or an integer fraction (1/4, 1/3, 1/2) or an integer multiple (2, 3, 4) of the form speed.

Sollen Verbindungsstellen hergestellt werden, wie sie in der DE-OS 1 611 536 beschreiben sind, wird der Heftstreifen durch entsprechende Ausbildung der Messer und der Gegenrolle gleichzeitig mit dem Aufdrücken auf die sich in Bewegung befindlichen Formularbahnen rechtwinklig abgebogen. Der Bahnbewegungsrichtung folgend, übernehmen danach angeschrägte Leisten das Einbiegen der Heftstreifen, während rotativ arbeitende Druckstempel die Enden der Heftstreifen zusammendrücken.If connection points are to be produced, as described in DE-OS 1 611 536, the tack strip is bent at right angles by appropriate design of the knives and the counter-roller simultaneously with the pressing onto the moving form webs. Following the direction of web movement, bevelled strips then take over the bending in of the tacking strips, while rotary pressure stamps compress the ends of the tacking strips.

Das Durchstecken, Andrücken und Anpressen der Laschenenden beim Herstellen der Verbindungsstellen nach DE-GM 1 899 831 erfolgt in bekannter Weise durch Stempel, Andrücker und Werkzeuge.The insertion, pressing and pressing of the tab ends when producing the connection points according to DE-GM 1 899 831 takes place in a known manner by means of stamps, pressers and tools.

In Figur 1 und 2 sind die Formularbahnen 1 angedeutet, die durch hier nicht dargestellte Werkzeuge an den Rändern mit Löchern 2 versehen wurden. Die Formularbahnen 1 bewegen sich in Pfeilrichtung mit einer vorgegebenen Geschwindigkeit durch die Vorrichtung. Während des Vorbeilaufens an dem rotierenden Körper 3 werden im Bereich der Löcher 2 Heftstreifen 4, welche auf der den Formularbahnen 1 zugewandten Seite mit einem Klebstoffauftrag versehen sind, auf die eine Außenseite der Formularbahnen 1 aufgedrückt. Dabei wird gleichzeitig der über die Seitenkante der Formularbahnen 1 hinausragende Teil der Heftstreifen 4 mit Hilfe der Gegenrolle 5 rechtwinklig abgebogen.In Figures 1 and 2, the form webs 1 are indicated, which were provided with holes 2 at the edges by tools, not shown here. The form webs 1 move through the device in the direction of the arrow at a predetermined speed. While the rotating body 3 is running past, in the region of the holes 2 tack strips 4, which are provided with an adhesive application on the side facing the form webs 1, onto which an outside of the form webs 1 is pressed. At the same time, the part of the adhesive strips 4 protruding beyond the side edge of the form webs 1 is bent at right angles with the aid of the counter roller 5.

Der Laufrichtung folgend werden die abgebogenen Enden der Heftstreifen 4 mittels der Leisten 6 umgelegt und anschließend im Bereich der Löcher 2 mit ihren Innenflächen durch die Anpreßwerkzeuge 7 und 8 zusammengedrückt und verklebt.Following the running direction, the bent ends of the tacking strips 4 are folded over by means of the strips 6 and then pressed and glued together with their inner surfaces in the region of the holes 2 by the pressing tools 7 and 8.

Die Ausführungsform nach Figur 4 unterscheidet sich dadurch, daß während die Formularbahnen 1 den rotierenden Körper 3 passieren, über Schlitze oder Löcher 2 selbstklebendes Laschenmaterial 9 mit dem rechten Ende auf eine Außenseite der Bahnen 1 derart aufgedrückt wird, daß es mit seinen Längsseiten in Formularbahnvorschubrichtung zeigt. Nach dem Aufdrücken des Laschenmaterials 9 werden die freien Enden desselben mittels Durchsteckwerkzeugen 10 durch die Löcher 2 gesteckt. Die aus den Formularbahnen 1 herausragenden Enden des Laschenmaterials 9 werden dann durch Bleche 11 an die Unterseite der Formularbahnen 1 angestreift. Schließlich wird das bügelartig umgelegte Laschenmaterial 9 von den Anpreßwerkzeugen 7 und 8 auf die Formularbahnen 1 gepreßt, so daß das Laschenmaterial 9 mit seinen Enden die obere und untere Formularbahn verbindet.The embodiment according to FIG. 4 differs in that while the form webs 1 pass through the rotating body 3, self-adhesive tab material 9 is pressed with the right end onto an outside of the webs 1 via slots or holes 2 such that its long sides point in the form web feed direction . After the tab material 9 has been pressed on, the free ends thereof are inserted through the holes 2 by means of push-through tools 10. The ends of the tab material 9 protruding from the form webs 1 are then touched by sheets 11 on the underside of the form webs 1. Finally, the strap-like folded tab material 9 is pressed onto the form webs 1 by the pressing tools 7 and 8, so that the ends of the tab material 9 connect the upper and lower form web.

Der Körper 3 ist über den Formularbahnen 1 in einer Konsole 12 mittels Kugellager 13 und Nadellager 14 um seine Achse 15 drehbar gelagert und wird durch seine Antriebsorgane 16 derart in Rotation versetzt, daß seine Umfangsgeschwindigkeit vorzugsweise gleich der Vorschubgeschwindigkeit der Formularbahnen 1 ist.The body 3 is rotatably mounted about the axis 15 above the form webs 1 in a console 12 by means of ball bearings 13 and needle bearings 14 and is set in rotation by its drive elements 16 such that its peripheral speed is preferably equal to the feed speed of the form webs 1.

In bzw. an dem drehbar gelagerten Körper 3 sind die Klebebandvorratsrollen 17, die Zugrollen 18 zum Abziehen des Klebebandes 19 und die Messer 20 zum Abschneiden der Heftstreifen 4 bzw. des Laschenmaterials 9 angeordnet.In or on the rotatably mounted body 3, the adhesive tape supply rollers 17, the pulling rollers 18 for pulling off the adhesive tape 19 and the knives 20 for cutting off the adhesive strips 4 or the tab material 9 are arranged.

Infolge der Rotation des Körpers 3 vollführen die Zugrollen 18, die mit Freiläufen 21 ausgestattet sind und mittels der Hebel 22 betätigt werden, die mit Kurvenrollen 23 an der feststehenden als Axialkurve ausgebildeten Kurve 24 abrollen, eine taktweise Drehbewegung. Dabei wird das Klebeband 19, das die Zugrollen 18 umschlingt, um ein bestimmtes Maß, welches von dem Hub der Kurve 24 abhängt, unterhalb der Messer 20 hindurchgeschoben.As a result of the rotation of the body 3, the traction rollers 18, which are equipped with freewheels 21 and are actuated by means of the levers 22, which roll with cam rollers 23 on the fixed curve 24 designed as an axial curve, perform a cyclical rotary movement. The adhesive tape 19, which wraps around the pulling rollers 18, is pushed through below the knives 20 by a certain amount, which depends on the stroke of the curve 24.

Die Federn 25 sorgen dafür, daß die Kurvenrollen 23 immer in Kontakt mit der feststehenden Axialkurve 24 bleiben. Ebenfalls infolge der Rotation des Körpers 3 werden die Messer 20 zum Abschneiden der Heft- bzw. Klebbandstreifen 4 bzw. des Laschenmaterials 9 von dem Klebeband 19 über Stifte 26 und Nadelhülsen 27, welche in der Nut 28 der feststehenden Nutkurve 29 abrollen, auf- und abgesteuert. Dabei werden die Heft- bzw. Klebbandstreifen 4 oder das Laschenmaterial 9 gleichzeitig auf die Formularbahnen gedrückt. Die Messer 20 sind mit Kerben 30 versehen, die in Zusammenarbeit mit dem schmalen erhöhten Rand 31 der Gegenrolle 5 die Heft- bzw. Klebbandstreifen 4 rechtwinklig nach unten abbiegen.The springs 25 ensure that the cam rollers 23 always remain in contact with the fixed axial cam 24. Also as a result of the rotation of the body 3, the knives 20 for cutting off the adhesive tape strips 4 or the tab material 9 from the adhesive tape 19 via pins 26 and needle sleeves 27, which roll in the groove 28 of the fixed groove curve 29, roll up and open taxed. The booklet or adhesive tape strips 4 or the tab material 9 are pressed onto the form webs at the same time. The knives 20 are provided with notches 30 which, in cooperation with the narrow, raised edge 31 of the counter roller 5, bend the strips of adhesive tape 4 at right angles downwards.

Die Ausführungsform nach Figur 7 unterscheidet sich von der nach Figur 6 darin, daß bei A schmale Querabschnitte von den Klebebändern 19 abgetrennt werden und deshalb der taktweise Vorschub der Klebebänder 19 durch die Zugrollen 18 geringer ist, was auch einen kleineren Hub der als Axialkurve ausgebildeten Kurve 24 zuläßt.The embodiment according to FIG. 7 differs from that according to FIG. 6 in that at A narrow cross sections are separated from the adhesive tapes 19 and therefore the intermittent feed of the adhesive tapes 19 by the pull rollers 18 is less, which also means a smaller stroke of the curve designed as an axial curve 24 permits.

Die Figuren 8 und 9 zeigen eine weitere Ausführungsform des Zugrollenantriebes, welcher über das Antriebsrad 32, die Welle 33 und die Schraubenräder 34 und 35 geleitet wird. Hierbei werden die Zugrollen 18 vorzugsweise kontinuierlich gedreht und fördern die Klebebänder 19 mit gleichmäßiger Geschwindigkeit unter die Schnittstellen bei A.FIGS. 8 and 9 show a further embodiment of the traction roller drive, which is guided via the drive wheel 32, the shaft 33 and the helical wheels 34 and 35. Here, the pulling rollers 18 are preferably rotated continuously and convey the adhesive tapes 19 at a uniform speed under the interfaces at A.

Die Länge der Heft- bzw. Klebbandstreifen 4 bzw. die Breite des Laschenmaterials 9 wird durch das Übersetzungsverhältnis der Antriebsräder 32 und 32 a und der Schraubenräder 34 und 35 bestimmt.The length of the tack or adhesive tape strips 4 or the width of the tab material 9 is determined by the transmission ratio of the drive wheels 32 and 32 a and the helical wheels 34 and 35.

Figur 10 veranschaulicht die Umlenkung der Klebebänder 19 mittels Führungsstäbe 36 und 37, nachdem sie von den auf dem Zapfen 38 angeordneten KIebebandvorratsrollen 17 abgezogen wurden.FIG. 10 illustrates the deflection of the adhesive tapes 19 by means of guide rods 36 and 37 after they have been removed from the tape supply rolls 17 arranged on the pin 38.
