Aus der DE 102 41 448 ist eine Faltschachtelmaschine bekannt, die dazu dient, Faltschachtelzuschnitte in Faltschachtelschläuche umzuformen. Die Faltschachtelzuschnitte entsprechen der Abwicklung einer herzustellenden fertigen Faltschachtel. Das Umfalten muß mit erheblicher Präzision geschehen, denn hierdurch wird die Winkeltreue der fertigen Faltschachtel entscheidend besti m mt.From DE 102 41 448 a folding carton machine is known which serves to Folding carton blanks into folding carton hoses. The Faltschachtelzuschnitte correspond to the settlement of a manufactured finished folding carton. The folding must be done with considerable precision because this makes the angular accuracy of the finished carton crucial certainly.

Um den Faltschachtelschlauch zu produzieren, werden sogenannte Faltriemen oder Faltbänder verwendet, die sich an die umzuschlagenden Teile, die Seitenteile des Faltschachtelzuschnitts anlegen und das Falten längs der Faltlinie erzwingen. Die Faltriemen laufen mit ihrem Arbeitstrum längs einer Art Schraubenlinie, wobei der Faltriemen auf die einzufaltenden Teile einwirken. Damit die Faltbewegung ordnungsgemäß vonstatten geht, laufen die Faltriemen mit einer Bahngeschwindigkeit, die der Bahngeschwindigkeit des Zuschnitts entspricht. Um die Winkeltreue der fertigen Faltschachtel zu gewährleisten, sind in der Faltlinie eine Vielzahl lose drehbarer Scheiben angeordnet, die in der Nähe der Faltlinien den Faltschachtelzuschnitt berühren.To produce the carton tube, so-called folding belt or folding tapes, which adhere to the parts to be handled, the Create side panels of the folding carton blank and fold along the Force fold line.

Eine weitere Faltstation zum Falten von Zuschnitten ist aus der DE 44 39 198 A1 bekannt. Das Falten erfolgt in an sich bekannter Weise durch sogenannte Faltriemen, welche die Seitenklappen von unten ergreifen. Die Faltriemen verlaufen dabei von einer Ebene unterhalb zu einer Ebene oberhalb des Mittelteils. Die Achsen der Faltriemen sind hierbei derart zueinander verschränkt, dass sich die dem Zuschnitt zugewandte Faltriemenfläche entlang des Förderweges des Zuschnitts um insgesamt 180° wendet. Um die vorgegebenen engen Toleranzen beim Falten der Zuschnitte einzuhalten, ist im vorderen Bereich des Förderweges eine Abkantvorrichtung im Bereich der Falzlinien der Zuschnitte angeordnet.Another folding station for folding blanks is known from DE 44 39 198 A1 known. The folding takes place in a conventional manner by so-called Folding straps that grab the side flaps from below. The folding belts run from a level below to a level above the Middle part. The axes of the folding belt are in this case to each other entangled that the folding belt facing the blank along of the conveying path of the blank by a total of 180 ° turns. To the to comply with predetermined tight tolerances when folding the blanks, is in Front region of the conveying path a folding device in the field of Fold lines of the blanks arranged.

In the first region 12 of the folding belt 8 by means of a Faltweiche 16 by 90 ° diverted. Due to the deflection of the folding belt 8 is also the same time Side part of the blank placed at 90 °. The side part is thus at a right angle to the plane of the transport direction and is vertical to the middle part of the blank. Behind the first region 12 follows the middle Area 13, which in this embodiment with three pulleys, the so-called triple roll 13 ', (see Fig. 5) is executed. These pulleys serve to stabilize the guidance of the folding belt 8. In the rear and third area 15 of the folding station 3, the folding belt 8 over a number of Pressure rollers 14 by another 90 ° in the direction of the plane of the flat lying Area of blanks out.

Erfindungsgemäß ist der Faltriemen 8 zur Faltlinie einstellbar ausgeführt. Hierzu sind Faltweiche 16, Dreierrolle 13' und die Andrückrollen 14 auf einer Linearführung 17 mittels Verstelleinrichtungen 18 gehalten. Durch die Verstelleinrichtungen 18 ist nun erfindungsgemäß die Möglichkeit geschaffen, die Faltweiche 16, die Dreierrolle 13' und die Andrückrollen 14 horizontal und vertikal zu verstellen. Die Verstellung erfolgt in diesem dargestellten Ausführungsbeispiel kraftschlüssig über in Schlitzen 19 angeordnete Schrauben 20, siehe hierzu insbesondere die Figuren 4 und 5. Hierbei ist aus Gründen der Übersichtlichkeit lediglich eine Verstelleinrichtung 18 mit den Bezugszeichen 19, 20 bezeichnet. Es ist natürlich selbstverständlich, dass auch die anderen Verstelleinrichtungen mit Schlitzen 19 und Schrauben 20 versehen sind. Die Faltweiche 16 ist ebenfalls mit Langlöchern 19 versehen. Durch die Aufnahme der Andrückrollen 14 auf einem separaten Schlitten 21, siehe insbesondere Figur 5, ist das Einstellen der Andrückrollen 14 sehr leicht ausführbar. Auch die Dreierrolle 13' und die Faltweiche 16 sind in adäquater Weise gehalten und einstellbar. Deutlich zu erkennen ist die Einstellung über die Schlitze 19 in den Figuren 4 und 5.According to the folding belt 8 is designed to fold line adjustable. For this are Faltweiche 16, triple roll 13 'and the pressure rollers 14 on one Linear guide 17 held by adjusting 18. By the Adjustment means 18 is now inventively created the possibility the folding switch 16, the triple roller 13 'and the pressure rollers 14 horizontally and to adjust vertically. The adjustment takes place in this illustrated Embodiment frictionally over arranged in slots 19 screws 20, see in particular Figures 4 and 5. Here, for reasons of Clarity only an adjustment 18 with the reference numerals 19, 20 denotes. It goes without saying that the others too Adjusting devices with slots 19 and screws 20 are provided. The Faltweiche 16 is also provided with slots 19. By the recording the pressure rollers 14 on a separate carriage 21, see in particular FIG. 5, the adjustment of the pressure rollers 14 is very easy to carry out. Also the Dreierrolle 13 'and the folding switch 16 are held in an adequate manner and adjustable. Clearly visible is the setting on the slots 19 in the FIGS. 4 and 5.

Damit der Faltriemen 8 auch direkt im Einführbereich der Zuschnitte optimal an den Seitenteilen der Zuschnitte angreift, ist auch die Stellrolle 10 einstellbar ausgeführt. Der Faltriemen 8 wird über die Umlenkrolle 9 zur Stellrolle 10 geführt. Die Stellrolle 10 kann insbesondere mittels eines Spindeltriebes mit einer Stellschraube 22, die in Richtung des Pfeils P drehbar ist, in ihrer Position verändert werden. Beispielhaft soll die Einstellung an der Figur 6 verdeutlicht werden. Wird mittels der Stellschraube 22 die Stellrolle 10 in ihrer Position verändert, wie mit dem Pfeil M dargestellt, so wandert der Faltriemen 8 über die Umlenkrolle 11 entsprechend in Richtung des Pfeils B. Dadurch ist die Möglichkeit geschaffen, den Faltriemen 8 mit einfachsten Mitteln unmittelbar beim Einführen der Zuschnitte auf den richtigen Angriffspunkt der zu faltenden Seitenteile einzustellen. So that the folding belt 8 also optimally directly in the insertion of the blanks engages the side panels of the blanks, the adjusting roller 10 is adjustable executed. The folding belt 8 is about the deflection roller 9 to the adjusting roller 10th guided. The actuating roller 10 can in particular by means of a spindle drive with a set screw 22 which is rotatable in the direction of the arrow P, in its position to be changed. By way of example, the setting on FIG. 6 is intended to illustrate this become. Is by means of the adjusting screw 22, the adjusting roller 10 in position changed, as shown by the arrow M, the folding belt 8 moves over the Deflection pulley 11 accordingly in the direction of arrow B. This is the Possibility created, the folding belt 8 with the simplest means immediately when inserting the blanks on the correct point of application of the folding Adjust side panels.

Die Möglichkeit der Einstellung des Faltriemens 8 bietet den Vorteil, die Faltschachteln im Bereich der Fertigfaltstation 3 optimal falten zu können. Hierbei ist es immer sinnvoll, den Faltriemen 8 möglichst weit entfernt von der Faltlinie oder Rilllinie angreifen zu lassen, um Fehler beim winkelgetreuen Falten, dieser Effekt wird auch als Fish-tailing bezeichnet, so gering wie möglich zu halten und einen optimalen Angriffspunkt zu erhalten. In allen bisher bekannten Faltschachtelklebemaschinen liegt der Angriffspunkt immer in unmittelbarer Nähe direkt an der umzulegenden Rillenlinie. Durch den erfindungsgemäßen Gedanken ist nun die Möglichkeit geschaffen, dass der Faltriemen 8 im vorderen auflaufenden Bereich 12 seitlich verstellbar ist. In der nachfolgenden Faltweiche 16, in der die Verdrehung des Faltriemens 8 von 0° bis 90° geschieht, ist die Faltweiche 16 im vorderen Bereich seitlich und im hinteren Bereich höhenverstellbar befestigt. The possibility of adjusting the folding belt 8 offers the advantage that Folding cartons in the area of the unfolding station 3 optimally folding. It is always useful, the folding belt 8 as far away from the Folding line or score line to make mistakes in the true to the angle Wrinkles, this effect is also known as fish-tailing, as low as possible to hold and to get an optimal attack point. In all so far known Faltschachtelklebaschinen the point of attack is always in immediate proximity to the umbilical groove line. By the inventive idea is now created the possibility that the Folding belt 8 in the front accumulating area 12 is laterally adjustable. In the subsequent folding switch 16, in which the rotation of the folding belt 8 of 0 ° up to 90 °, the folding switch 16 is in the front area laterally and in the rear adjustable height adjustable.
