Description

Die Erfindung betrifft eine Vorrichtung zum maschinellen Herstellen einer Schrägfalte am Anfang einer fortlaufenden Papierbahn in einer Maschine zum maschinellen Falten von Bogen wie Zeichnungspausen o. dgl.The invention relates to a device for the mechanical production of an oblique fold at the beginning of a continuous paper web in a machine for the mechanical folding of sheets such as drawing pauses or the like.

Zeichnungspausen der Größen DiN A 3. A 2, A 1, A 0, 2 A 0 wie auch Wildmaß-Zwischengrößen werden nach bestimmten Regeln (DIN 824) so gefaltet, daß sie als Paket wie Bogen der Größe DIN A 4 abgeheftet und im eingehefteten Zustand auch auseinandergeklappt werden können. Damit die über die Querfalten eingeklappten Zeichnungsteile nicht vom Heftmechanismus erfaßt werden, werden diese Teile durch eine Schrägfaltung als Umschlag aus dem Bereich der Heftlöcher herausgefaltet.Drawing breaks of sizes DiN A 3. A 2, A 1, A 0, 2 A 0 as well as intermediate sizes of wild size are folded according to certain rules (DIN 824) so that they are filed as a package like sheets of size A4 and bound in Condition can also be unfolded. So that the drawing parts folded over the transverse folds are not caught by the stapling mechanism, these parts are folded out of the area of the stapling holes by a diagonal fold as a cover.

Diese bei der Handfaltung üblichen Schrägfalten waren mit Maschinen zum maschinellen Falten nur sehr umständlich herzustellen. Aus der DE-A-18 12557 ist bereits eine Maschine zum Zick-Zack-Falten von Bogen bekannt, in der der Bogen einem stationären Falttisch zugeführt und durch Absenken eines dreieckförmigen Tischteils mit einer Schrägfalte versehen wird. Der auf diese Weise gebildete Umschlag wird festgehalten, und die Schrägfalte sowie weitere, danach gebildete Längsfalten werden anschließend durch Hin- und Herfahren eines Faltwalzenwagens ausgewalzt.These oblique folds, which are common in manual folding, were very difficult to produce with machines for mechanical folding. From DE-A-18 12557 a machine for zigzag folding of sheets is already known, in which the sheet is fed to a stationary folding table and is provided with an oblique fold by lowering a triangular table part. The envelope formed in this way is held in place, and the oblique fold and further longitudinal folds formed thereafter are then rolled out by moving a folding roller carriage back and forth.

Erfolgt die Herstellung der Längsfalten jedoch im Durchlaufverfahren, bei dem der Bogen von ortsfesten Zuführwalzen in die (mit hoher Geschwindigkeit arbeitende) Maschine eingeführt und der Bogenanfang bzw. das teilweise fertiggefaltete Bogenpaket insbesondere von reversierbaren, also in der Drehbewegung umsteuerbaren, aber ortsfesten Faltwalzen hin- und herbewegt wird, so kann die Schrägfalte nicht wie bei der bekannten Maschine durch einen auf- und abbewegbaren dreieckförmigen Tisch hergestellt werden, weil hierzu ein Stillstand des Bogens erforderlich wäre. Da bei durchlaufendem Bogen mit dem Falten auch nicht am (in Laufrichtung gesehen) hinteren Ende der Schrägfalte begonnen werden kann, ergibt sich die Schwierigkeit, am vorderen spitzwinkligen Ende der Schrägfalte beginnen zu müssen.However, the longitudinal folds are produced in a continuous process, in which the sheet is introduced into the machine (working at high speed) from stationary feed rollers and the beginning of the sheet or the partially finished sheet package, in particular from reversible, that is to say reversible in rotation, but stationary folding rollers. and is moved, the oblique fold can not be produced as in the known machine by an up and down movable triangular table, because this would require a standstill of the sheet. Since it is not possible to start folding at the rear end of the oblique fold (seen in the direction of travel) when the sheet is running through, the difficulty arises of having to start at the front acute-angled end of the oblique fold.

Es ist außerdem bekannt, anstelle der Schrägfalte den Randbereich der Bogen durch Ausstanzungen auszuklinken, damit dieser Bereich nicht vom Heftmechanismus erfaßt wird. Diese Ausklinkungen sind jedoch von Nachteil, weil bei eingehefteten Zeichnungen der Heftmechanismus gelöst werden muß, um das Herausklappen der sonst eingeklemmten quergefalteten Zeichnungsteile zu ermöglichen. Außerdem besteht die Gefahr, daß Informationen verlorengehen.It is also known to notch out the edge area of the sheet by punching out the oblique fold so that this area is not caught by the stapling mechanism. These notches are disadvantageous, however, because the stapling mechanism has to be loosened in the case of stapled-in drawings in order to enable the otherwise trapped cross-folded drawing parts to be folded out. There is also a risk of information being lost.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung für eine Maschine zum maschinellen Falten von Bogen vorzuschlagen, die die sichere maschinelle Herstellung von Schrägfalten auch bei Maschinen nach dem Durchlaufverfahren ermöglicht.The invention is based on the object of proposing a device for a machine for the mechanical folding of sheets which enables the safe mechanical production of oblique folds even in machines using the continuous process.

Diese Aufgabe wird gelöst durch eine spiralförmig auf dem Umfang einer Walze angeordnete Faltenbruchleiste und eine Gegenwalze aus nachgiebigem Material zum Vorprägen der Schrägfalte des Umschlages sowie eine nachgeschaltete Anordnung zum Umlegen des Umschlages und Scharfknicken der vorgeprägten Schrägfalte.This object is achieved by a fold fold bar arranged spirally on the circumference of a roller and a counter roller made of resilient material for pre-embossing the oblique fold of the envelope and a subsequent arrangement for folding over the envelope and sharp bending of the pre-embossed oblique fold.

Besondere Vorteile ergeben sich, wenn gemäß einer Weiterbildung der Erfindung der Winkel der Schrägfalte gegenüber dem Blattrand der Papierbahn für alle Formate gleich ist. Hierdurch wird es möglich, daß für alle Blattgrößen der Neigungswinkel der spiralförmig angeordneten Faltenbruchleiste gegenüber der Achsrichtung der Walze gleich ist.Particular advantages result if, according to a development of the invention, the angle of the oblique fold relative to the sheet edge of the paper web is the same for all formats. This makes it possible for the angle of inclination of the spiral fold fold bar to be the same for all sheet sizes with respect to the axial direction of the roller.

Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.Further advantageous refinements can be found in the subclaims.

Der Gegenstand der Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert. Es zeigen :

  • Fig. 1 eine schematische Seitenansicht der erfindungsgemäßen Vorrichtung in einer ersten Arbeitsposition,
  • Fig. 2 die Vorrichtung nach Fig. 1 in einer zweiten Arbeitsposition,
  • Fig. 3 die Vorrichtung nach Fig. 1 in einer dritten Arbeitsposition,
  • Fig. 4 eine Ansicht der Vorrichtung in der Arbeitsposition gemäß Fig. 3 von oben,
  • Fig. 5 einen Ausschnitt aus einem Bogen der Größe DIN A 1 und
  • Fig. 6 einen Ausschnitt aus einem Bogen der Größe DIN A 0.
The subject matter of the invention is explained in more detail below using an exemplary embodiment. Show it :
  • 1 is a schematic side view of the device according to the invention in a first working position,
  • 2 shows the device according to FIG. 1 in a second working position,
  • 3 shows the device according to FIG. 1 in a third working position,
  • 4 is a view of the device in the working position according to FIG. 3 from above,
  • Fig. 5 shows a section of a sheet size DIN A 1 and
  • 6 shows a section of a sheet of size DIN A 0.

Die in den Fig. 1 bis 4 gezeigte Vorrichtung enthält am Anfang einlaufwalzenpaar 2, mit dem eine Papierbahn 1 (z. B. Zeichnungspause) in Pfeilrichtung in die Vorrichtung hineintransportiert wird (Fig. 1). Sobald die Vorderkante der Papierbahn 1 einen Sensor 3 erreicht, wird eine mit geringem Abstand vom Walzenpaar 2 angeordnete Walze 9 durch eine Eintourenkupplung 19 in Drehung versetzt. Die Walze 9 trägt auf ihrem Umfang eine spiralförmig angeordnete Faltenbruchleiste 5, mit der die Papierbahn 1 in die darunter angeordnete, mit einem nachgiebigen Belag (z. B. Gummibelag) versehene Gegenwalze 4 eingedrückt wird (Fig. 2), so daß sich durch Einprägen eine Schrägfalte 8 in der Papierbahn 1 ergibt. Ist eine Umdrehung vollendet, wird die Walze 9 stillgesetzt und befindet sich in Warteposition (Fig. 3). Die Leiste 5 und die Gegenwalze 4 sind so ausgebildet und angeordnet, daß sich zugleich mit dem Einprägen der Schrägfalte 8 der von dieser abgeteilte Umschlag 6 gegenüber der übrigen Papierbahn 1 unter einem Winkel (nach oben) anstellt.The device shown in FIGS. 1 to 4 initially contains a pair of infeed rollers 2 with which a paper web 1 (e.g. drawing pause) is transported into the device in the direction of the arrow (FIG. 1). As soon as the front edge of the paper web 1 reaches a sensor 3, a roller 9 arranged at a short distance from the pair of rollers 2 is rotated by a single-speed clutch 19. The roller 9 carries on its circumference a spirally arranged fold break bar 5 with which the paper web 1 is pressed into the counter roller 4 arranged underneath it, provided with a flexible covering (e.g. rubber covering) (FIG. 2), so that it is stamped in an oblique fold 8 results in the paper web 1. When one revolution has been completed, the roller 9 is stopped and is in the waiting position (FIG. 3). The strip 5 and the counter-roller 4 are designed and arranged such that the envelope 6 divided by the diagonal fold 8 is positioned at an angle (upwards) with the impression of the oblique fold 8.

Die Papierbahn 1 wird weiter nach rechts (in der Zeichnung gesehen) transportiert und der durch die Schrägfalte 8 gebildete, noch offene Umschlag 6 gelangt in den Bereich einer Bürstenwalze 10. Die Bürstenwalze 10 ist nicht angetrieben und wirkt daher als Hemmglied für den angestellten Umschlag 6, der sich deshalb in seinem Anfangsbereich 6a umlegt, wobei sich die Bürstenwalze (in den Fig. 1 bis im Gegen-Uhrzeigersinn) dreht. Beim weiteren Vorlauf der Papierbahn 1 gelangt der weitere Umschlagbereich 6b in den Arbeitsbereich eines schräggestellten Niederhalterstabes 12, der den bereits im Anfangsbereich 6a umgelegten Umschlag 6 auch im Restbereich 6b umlegt. Der Stab 12 ist ebenfalls frei drehbar gelagert, steht aber auch im Betrieb praktisch still.The paper web 1 is transported further to the right (as seen in the drawing) and the still open envelope 6 formed by the oblique fold 8 reaches the area of a brush roller 10. The brush roller 10 is not driven and therefore acts as an inhibiting member for the employed envelope 6, which therefore turns over in its initial region 6a, the brush roller rotating (in FIG. 1 counterclockwise). When the paper web 1 is advanced, the further envelope area 6b reaches the working area of an inclined hold-down rod 12, which also folds the envelope 6 already folded over in the initial area 6a in the remaining area 6b. The rod 12 is also freely rotatable, but is practically still during operation.

Sobald der Umschlag 6 in der Umlegestation 10, 11 vollständig umgelegt worden ist, gelangt der vordere Bogenrand 11 der Papierbahn 1 in den Arbeitsbereich eines nachgeschalteten Walzenpaares 18 zum Scharfknicken der Schrägfalte 8. Damit ist der gewünschte Umschlag 6 mit der Schrägfalte 8 hergestellt ; das Walzenpaar 18 sorgt zugleich für den Weitertransport der Papierbahn 1.As soon as the envelope 6 has been completely folded over in the folding station 10, 11, the front sheet edge 11 of the paper web 1 enters the working area of a downstream pair of rollers 18 for sharp bending of the oblique fold 8. The desired envelope 6 with the oblique fold 8 is thus produced; the pair of rollers 18 also ensures the further transport of the paper web 1.

Aus den Fig. 5 und 6 geht im einzelnen hervor, in welcher Breite der Umschlag 6 mit der Schrägfalte 8 hergestellt wird.5 and 6 show in detail the width of the envelope 6 with the oblique fold 8.

Fig. 5 zeigt einen Ausschnitt aus einem zu faltenden Bogen 30 der Größe DIN A 1, in dem am linken Bogenrand 11 (Heftrand) im unteren Bereich Heftlöcher 16 vorgesehen sind. Nach Ausführung der Längsfalten 14 erfolgt die Querfaltung um die Querfalte 13, so daß ohne Schrägfalte 8 der Bereich des Umschlages 6 in den Bereich der Heftlöcher 16 zu liegen käme. Aus diesem Grund wird der Umschlag 6 um die Schrägfalte 8 gebildet, was durch die gestrichelte Linie 15 angedeutet wird. Wird nun der obere Teil des Bogens 10 um die Querfalte 13 nach unten geklappt, so kommen die Begrenzungen entlang der Schrägfalte 8 entsprechend der gestrichelten Linie 17 von den Heftlöchern 16 frei. Hierzu muß der Winkel 7 mindestens 6° betragen (bei DIN 2 A 0 entsprechend DIN 824 : 6,72°).5 shows a section of a sheet 30 of size DIN A1 to be folded, in which stitching holes 16 are provided in the lower region on the left sheet edge 11 (binding edge). After the longitudinal folds 14 have been carried out, the transverse folding takes place around the transverse fold 13, so that without the oblique fold 8 the area of the envelope 6 would come to lie in the area of the stitching holes 16. For this reason, the envelope 6 is formed around the oblique fold 8, which is indicated by the dashed line 15. If the upper part of the sheet 10 is now folded down about the transverse fold 13, the boundaries along the oblique fold 8 are released from the stitching holes 16 in accordance with the dashed line 17. For this, the angle 7 must be at least 6 ° (with DIN 2 A 0 according to DIN 824: 6.72 °).

Fig. 6 zeigt einen Ausschnitt aus einem zu faltenden Bogen 40 der Größe DIN A 0, bei dem zwei Bereiche in senkrechter Richtung bei der Querfaltung umgeklappt werden müssen. Auch hier kommt es darauf an, durch Anlegen einer Schrägfalte 8 den oberen Bogenbereich aus dem Bereich der Heftlöcher 16 herauszubringen. Die Schrägfalte 8 hat in diesem Fall den gleichen Winkel 7 wie bei der Fig. 5.6 shows a section of a sheet 40 of size DIN A 0 to be folded, in which two areas have to be folded over in the vertical direction during the transverse folding. Here, too, it is important to bring the upper arch area out of the area of the stitching holes 16 by applying an oblique fold 8. In this case, the oblique fold 8 has the same angle 7 as in FIG. 5.

Dadurch, daß für alle Bogengrößen der gleiche Winkel 7 von mindestens 6° für die Schrägfalte 6 vorgesehen wird, ist es möglich, für alle Bogengrößen mit einer Faltvorrichtung zur Erzeugung des Schrägfalte 6 auszukommen, ohne daß diese umgeschalten werden muß. Der Neigungswinkel der spiralförmig angeordneten Faltenbruchleiste 5 gegenüber der Achsrichtung der Walze 9 ist dabei gleich dem Winkel 7 der Schrägfalte 8.Characterized in that the same angle 7 of at least 6 ° is provided for the oblique fold 6 for all sheet sizes, it is possible to get by with a folding device for producing the oblique fold 6 for all sheet sizes without this having to be switched over. The angle of inclination of the spiral fold fold bar 5 with respect to the axial direction of the roller 9 is equal to the angle 7 of the oblique fold 8.

Anstelle der Bürstenwalze 10 kann auch ein Umlegeblech oder ein anderes in den Weg des angestellten Umschlages 6. ragendes starres Hemmglied vorgesehen sein. Des weiteren kann eine Walze des Walzenpaares 18 als Segmentwalze ausgebildet sein.Instead of the brush roller 10, it is also possible to provide a folding sheet or another rigid locking member projecting into the path of the folded envelope 6. Furthermore, one roller of the pair of rollers 18 can be designed as a segment roller.
