Abstract

The device for folding packaging bags and letter envelopes involving closure flaps with or without closure flaps and with or without self-adhesive strips entails the bag or envelope moved against a stationary stop. The flap and counter flap are positioned by suction components (7,9) arranged on a counter flap roller (6) and a closure flap roller (8). The radius of the counter flap roller supporting the corresponding suction component is at least partly reduced. The counter flap roller is so securable that a folding product is movable past it to the stationary stop without contact or virtually so.

Description

Die Erfindung betrifft eine Vorrichtung zum Falten von Faltprodukten mit Schließklappen sowie mit oder ohne Gegenklappen, insbesondere an Verpackungsbeuteln einschließlich Briefhüllen mit den Merkmalen des Oberbegriffes von Anspruch 1.The invention relates to a device for folding folded products with closing flaps and with or without counter flaps, in particular on packaging bags including envelopes with the characteristics the preamble of claim 1.

Seit vielen Jahren befinden sich Vorrichtungen der hier interessierenden Art auf dem Markt und werden in grossem Umfang bei der Herstellung von Verpackungsbeuteln einschließlich Briefhüllen eingesetzt. Zum Umlegen der Gegenklappen und der Schliessklappen werden die fast fertiggestellten Verpackungsbeutel bzw. Briefhüllen an einem Anschlag angehalten und sodann bei der anschliessenden, entgegen gesetzten Bewegung mit Hilfe von Saugelementen auf einer Gegenklappenwalze bzw. auf einer Schliessklappenwalze umgefaltet und sodann weitertransportiert und z. B. mit Hilfe einer Fächerscheibe abgelegt.For many years there have been devices of interest here Art on the market and are widely used in manufacturing of packaging bags including envelopes used. To flip the counter flaps and the closing flaps Almost finished packaging bags or envelopes at one stop stopped and then at the subsequent opposite one Movement with the help of suction elements on a counter flap roller or folded over on a flap roller and then transported and z. B. filed with the help of a serrated lock washer.

Darüber hinaus ist aus der DE 22 18 085 C2 eine Vorrichtung zum Falten der Schliess- und Gegenklappen an Briefhüllen mit Selbstklebegummierung bekannt, wobei das Abheben und Umlegen der Klappen mit Hilfe von zwei Saugwalzen erfolgt. Ferner sind in der einen Saugwalze eine Aussparung und benachbart dazu eine Saugleiste angeordnet.In addition, DE 22 18 085 C2 describes a device for Folding the closing and counter flaps on envelopes with self-adhesive rubber known, taking off and flipping the flaps with the help of two suction rolls. Furthermore, there is a suction roller a recess and adjacent to a squeegee.

Die aus der DE 22 18 085 C2 bekannte Vorrichtung arbeitet deutlich langsamer als die auf dem Markt befindliche Faltvorrichtung und ist aus diesem Grund technisch überholt. Hinzu kommt noch, dass die auf dem Markt befindliche Faltvorrichtung auch zur Herstellung von anderen Briefhüllen geeignet ist, die keine Selbstklebegummierung auf der Schließklappe und statt dessen einen anderen, zum Beispiel beim Befeuchten wirksam werdenden Haftkleber und auch keine Gegenklappe aufweisen. Dazu muss jedoch eine Saugwalze, d. h. die Saugwalze mit dem Saugelement für die Gegenklappe mit ihrem Antrieb vollständig aus der Bewegungsbahn des fertigzustellenden Faltproduktes bzw. der fertigzustellenden Briefhülle herausgeschwenkt werden. Der damit verbundene technische Aufwand ist erheblich und soll vermieden werden.The device known from DE 22 18 085 C2 works clearly slower than the folding device on the market and is off technically out of date for this reason. In addition, the on the Folding device on the market also for the production of others Envelopes are suitable that have no self-adhesive rubber on the Closing flap and another instead, for example when moistening effective adhesive and no counter flap exhibit. To do this, however, a suction roller, i. H. the suction roller with the suction element for the counter flap with its drive completely from the trajectory of the folding product to be finished or the to be finished swung out envelope. The related technical effort is considerable and should be avoided.

Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen des kennzeichnenden Teiles von Anspruch 1 vor, dass der Radius der Gegenklappenwalze, die das die Gegenklappen umlegende Saugelement trägt, mindestens teilweise derart gering ist und dass die Gegenklappenwalze derart arretierbar ist, dass ein Faltprodukt auch kontaktfrei oder nahezu kontaktfrei an ihr vorbei zu dem stationären Anschlag bewegbar ist.To achieve this object, the invention provides with the features of characterizing part of claim 1 that the radius of the counter-valve roller, the suction element that folds the counter flaps is at least partially so low and that the counter-valve roller can be locked in such a way that a folded product is also contact-free or can be moved almost without contact past it to the stationary stop is.

Mit Hilfe der besagten Merkmale ist es möglich, auf ein und derselben Vorrichtung Verpackungsbeutel einschließlich Briefumschläge mit Schließklappe und Gegenklappe einerseits oder nur mit Schließklappe andererseits herzustellen, wobei ein Umbau der Vorrichtung nicht erforderlich ist und lediglich die Gegenklappenwalze in einer definierten Position stillgesetzt werden muß. Die definierte Position ist dann gegeben, wenn sich der Verpackungsbeutel bzw. die Briefhülle von der Schließklappenwalze in Richtung des stationären Anschlages bewegen kann, ohne dass sie dabei wesentlich die Gegenklappenwalze berührt. Somit lassen sich verschiedenartige Briefhüllen auf ein und derselben Maschine problemlos fertigstellen. Die hierzu erfindungsgemäß vorgesehenen Merkmale sind nicht nur technisch weniger aufwendig und auch billiger bei der Herstellung, sondern sie lassen sich auch schneller und einfacher handhaben als die vergleichbaren Maßnahmen nach dem Stand der Technik.With the help of said features it is possible to work on one and the same Device packaging bags including envelopes with Closing flap and counter flap on the one hand or only with a closing flap to produce on the other hand, a conversion of the device not being necessary is and only the counter valve roller in a defined Position must be stopped. The defined position is then given if the packaging bag or the envelope from the Move the shutter flap roller in the direction of the stationary stop can without substantially touching the counter-valve roller. This means that different types of envelopes can be placed on one and the same Complete the machine without any problems. The provided for this purpose according to the invention Features are not only technically less complex and also cheaper to manufacture, but they can also be faster and easier to use than the comparable measures after the State of the art.

Ferner ist erfindungsgemäss vorgesehen, dass mindestens ein Saug-element auf der Gegenklappenwalze angeordnet ist und über einen zylindrischen Umfang der Gegenklappenwalze vorsteht. Das Saugelement ist nicht mehr - wie beim Stand der Technik - in den Umfang der Gegenklappenwalze integriert und schliesst zumindest teilweise mit diesem bündig ab, sondern es erhebt sich wie ein Mitnehmer oder Finger über den Umfang der Gegenklappenwalze. Dennoch ist das Saugelement bei der Herstellung von Briefhüllen mit Selbstklebegummierung auf beiden Klappen in der Lage, die von ihm umzulegende Gegenklappe sicher und zuverlässig zu erfassen, insbesondere weil die Briefhülle gleichzeitig noch mit Hilfe der Schliessklappenwalze stabilisiert wird. Das Saugelement der Schliessklappenwalze gibt die Schliessklappe in diesem Fall erst frei, wenn das Saugelement der Gegenklappenwalze die Gegenklappe vollständig oder nahezu vollständig umgefaltet hat.
Weitere Merkmale der Erfindung gehen aus Unteransprüchen und der Beschreibung im Zusammenhang mit der Zeichnung hervor.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles, das in der Zeichnung dargestellt ist, näher beschrieben. Dabei zeigen:

It is further provided according to the invention that at least one suction element is arranged on the counter flap roller and protrudes over a cylindrical circumference of the counter flap roller. The suction element is no longer - as in the prior art - integrated in the circumference of the counter flap roller and is at least partially flush with it, but rather rises like a driver or finger over the circumference of the counter flap roller. Nevertheless, the suction element in the production of envelopes with self-adhesive rubber on both flaps is able to reliably and reliably grasp the counter flap to be flipped over, in particular because the envelope is also stabilized with the help of the closing flap roller. In this case, the suction element of the closing flap roller only releases the closing flap when the suction element of the counter flap roller has folded the counter flap completely or almost completely.
Further features of the invention emerge from the dependent claims and the description in connection with the drawing.
The invention is described below with reference to an embodiment which is shown in the drawing. Show:

Ein Faltprodukt in Gestalt einer Briefhülle 1 weist gemäss Fig. 1 eine noch nicht umgefaltete Schliessklappe 2 mit einem Vorbruch 2' und mit einer Selbstklebegummierung 2'' sowie eine noch nicht umgefaltete Gegenklappe 3 mit einem zugehörigen Vorbruch 3' und mit einer Selbstklebegummierung 3'' auf. In diesem Zustand werden die Briefhüllen 1 einzeln nacheinander mit vorauslaufender Bodenkante 4 einer Vorrichtung 5 gemäss Fig. 3 zum Umfalten von Schliessklappe 2 und Gegenklappe 3 zugeführt.A folded product in the form of an envelope 1 has one according to FIG closing flap 2 not yet folded over with an opening 2 'and with a 2 '' self-adhesive rubber coating and one that has not yet been folded over Counter flap 3 with an associated pre-break 3 'and with a Self-adhesive rubber lining 3 ''. The envelopes are in this condition 1 individually one after the other with leading bottom edge 4 one 3 for folding the closing flap 2 and Counter flap 3 supplied.

Die Vorrichtung 5 umfasst eine Gegenklappenwalze 6 mit eine Saug-element 7 und eine Schliessklappenwalze 8 mit einem Saugelement 9. Ferner ist ein Halte- und Führungselement 10 mit einem Anschlag 11 vorgesehen. Weitere Walzen 12 und 13 bzw. 14 und 15 mit oder ohne Saugelementen 16 dienen zum Zuführen der noch nicht fertiggestellten Briefhülle 1 bzw. zum Weitertransportieren der fertiggestellten Briefhülle 1' gemäss Fig. 2 mit jeweils umgefalteter Schliessklappe 2 und Gegenklappe 3.The device 5 comprises a counter flap roller 6 with a suction element 7 and a closing flap roller 8 with a suction element 9. Furthermore, a holding and guiding element 10 with a stop 11 intended. Further rollers 12 and 13 or 14 and 15 with or without Suction elements 16 serve to feed the not yet completed Envelope 1 or for further transport of the finished envelope 1 'according to FIG. 2, each with the closing flap 2 and Counter flap 3.

Die mit vorlaufender Bodenkante 4 in die Vorrichtung 5 geförderte Briefhülle 1 trifft zunächst auf das Halte- und Führungselement 10 und wird sodann an dem Anschlag 11 abgestoppt. Zuvor hat das Saugelement 7 der Gegenklappenwalze 6 die Gegenklappe 3 erfasst und gleichermaßen hat das Saugelement 9 der Schliessklappenwalze 8 die Schliessklappe 2 erfaßt (Fig. 4). Die Schliessklappenwalze 8 zieht die Briefhülle 1 nach Erreichen der in Fig. 4 dargestellten Position aus dem Halte - und Führungselement 10 wieder heraus, während sich die Gegenklappenwalze 6 im Uhrzeigersinn weiterdreht und die Gegenklappe 3 unmittelbar nach Erreichen der in Fig. 4 dargestellten Position freigibt. Bei der weiteren Bewegung der Briefhülle 1 werden die Schliessklappe 2 und die Gegenklappe 3 vollständig umgefaltet, wie dies in Fig.5 dargestellt ist. Daraufhin übernimmt die Walze 15 mit ihrem Saug-element 16 die fertiggestellte Briefhülle 1' und fördert sie in eine Ablage. Der geschilderte Verfahrensablauf findet bei allen jeweils eine Selbstklebegummierung aufweisenden Briefhüllen 1 mit noch nicht umgefalteten Schliessklappen 2 und Gegenklappen 3 statt.Conveyed into the device 5 with the leading bottom edge 4 Envelope 1 first meets the holding and guiding element 10 and is then stopped at the stop 11. Previously, the suction element 7 of the counter flap roller 6 detects the counter flap 3 and equally has the suction element 9 of the shutter valve roller 8 Closing flap 2 detects (Fig. 4). The shutter valve roller 8 pulls the Envelope 1 after reaching the position shown in Fig. 4 from the Hold and guide element 10 out again while the counter flap roller 6 continues clockwise and the counter flap 3 releases immediately after reaching the position shown in FIG. 4. As the envelope 1 moves further, the closing flap 2 and the counter flap 3 completely folded over, as shown in Fig.5 is shown. Then the roller 15 takes over with her Suction element 16 the finished envelope 1 'and promotes it in one Filing. The procedure described above takes place in each case Self-adhesive rubber envelopes 1 with not yet folded closing flaps 2 and counter flaps 3 instead.

Das Saugelement 7 ist eine Saugöffnungen 20 aufweisende Saugleiste 21 mit etwa segmentförmigem Querschnitt. Zu dem Saugelement 7 gehört ferner ein Anschlag 22, an dem die Gegenklappe 3 mit ihrem freien Rand 23 zeitweise anliegt (Fig. 4).The suction element 7 is a suction bar 20 with suction openings 21 with an approximately segment-shaped cross section. To the suction element 7 also includes a stop 22 on which the mating flap 3 with its free edge 23 is temporarily present (Fig. 4).

Die Ansteuerung der Saugöffnungen 21 in der Saugleiste 21 erfolgt taktgesteuert mit Hilfe eines grundsätzlichen bekannten und aus diesem Grund hier nicht näher interessierenden Unterdruckerzeugers und einer geeigneten, grundsätzlich ebenfalls bekannten Saugluft- Steuereinrichtung.The suction openings 21 in the suction bar 21 are activated clock-controlled with the help of a basic known and from this Reason for negative pressure generator and not of interest here a suitable, basically also known suction control device.

Gemäß dem in den Figuren dargestellten Ausführungsbeispiel ist ein Saugelement 7 auf der Gegenklappenwalze 6 angeordnet und steht über einen zylindrischen Umfang 24 der Gegenklappenwalze 6 vor. Dies gilt nicht nur für den Anschlag 22, sondern insbesondere auch für die Lage der Saugöffnungen 20 in einer Fläche, die sich parallel zur Achse der Gegenklappenwalze 6 radial außerhalb des zylindrischen Umfanges 24 erstreckt. Der den zylindrischen Umfang 24 der Gegenklappenwalze 6 wesentlich bestimmende Radius r ist daher mindestens teilweise deutlich geringer als der Radius R, auf dem die Saugöffnungen 20 liegen (Fig. 5).According to the exemplary embodiment shown in the figures, a Suction element 7 arranged on the counter flap roller 6 and stands over a cylindrical circumference 24 of the counter-valve roller 6. This applies not only to the stop 22, but also in particular to the position of the suction openings 20 in a surface that is parallel to the Axis of the counter flap roller 6 radially outside the cylindrical Circumference 24 extends. The cylindrical circumference 24 of the counter-valve roller 6 essentially determining radius r is therefore at least sometimes significantly smaller than the radius R on which the suction openings 20 lie (Fig. 5).

Mit Hilfe der Durchmesserreduzierung für den zylindrischen Umfang 24 wird erreicht, dass ein Faltprodukt bzw. eine Briefhülle 1 gemäß Fig. 6 kontaktfrei oder nahezu ohne Kontakt mit der Gegenklappenwalze 6 zu dem Halte- und Führungselement 10 und seinem Anschlag 11 transportiert werden kann. Auch in diesem Fall ergreift die Schließklappenwalze 8 mit ihrem Saugelement 9 wie in dem zuerst beschriebenen Fall die Schließklappe 2 und legt sie in die Schließstellung.With the help of the diameter reduction for the cylindrical circumference 24 it is achieved that a folded product or an envelope 1 according to FIG. 6 contact-free or almost without contact with the counter flap roller 6 the holding and guiding element 10 and its stop 11 transported can be. In this case too, the shutter flap roller engages 8 with its suction element 9 as in the case described first the closing flap 2 and puts it in the closed position.
