Description

Die vorliegende Erfindung betrifft eine Kuvertiervorrichtung umfassend eine Packtasche, wobei die Packtasche mehrere Lamellen und eine Blattführung umfasst, sowie ein Verfahren zum Befüllen der Packtasche.The present invention relates to an enveloping device comprising a packing pocket, the packing pocket comprising a plurality of lamellae and a sheet guide, and a method for filling the packing pocket.

Aus der EP 0 504 114 B1 ist eine Kuvertiervorrichtung bekannt, die die Geschwindigkeit gegenüber dem damals bekannten Stand der Technik etwa verdoppeln kann. Dabei werden eine drehbar gelagerte Einpacktasche und eine Niederhalterolle über Hebel durch eine Kurve gesteuert. Die dadurch notwendige grosse Anzahl an schnell bewegten Teilen ist aufwendig in der Fertigung und hindert durch die relativ grosse bewegte Masse eine noch höhere Verpackungsleistung. Zudem führt die bewegte Einpacktasche zu unerwünschten Schwingungen, die ebenfalls die Verpackungsleistung begrenzen. Des Weiteren muss bei einer solchen Vorrichtung für jedes bezüglich der Breite, das heisst der Abmessung quer zur Transportrichtung des Kuverts, unterschiedliche Kuvertmass eine andere Packtasche montiert werden, die zudem nur für einen sehr begrenzten Bereich der Dicke des zu verpackenden Inhalts geeignet ist, um eine optimale Führung des Kuverts bzw. des durch die Packtasche zu führenden Kuvertinhalts zu gewährleisten. Aufgrund der beweglichen Führung der Packtasche ist ein solcher Tausch aufwendig.From the EP 0 504 114 B1 an inserting device is known which can approximately double the speed compared to the prior art known at the time. A rotatably mounted packing bag and a hold-down roller are controlled by a cam using levers. The large number of fast-moving parts required as a result is expensive to manufacture and, due to the relatively large moving mass, prevents even higher packaging performance. In addition, the moving packing bag leads to unwanted vibrations, which also limit the packing performance. Furthermore, with such a device, a different envelope size must be mounted for each envelope with respect to the width, i.e. the dimension transverse to the transport direction of the envelope, which is also only suitable for a very limited range of the thickness of the content to be packaged in order to to ensure optimum guidance of the envelope or of the envelope contents to be guided through the pannier. Such an exchange is complicated due to the movable guide of the pannier.

Aus der EP 2 756 964 A1 ist eine Kuvertiervorrichtung bekannt, bei der ein Kuvert auf Führungsklingen, die jeweils eine vom freien Ende her zunächst nach oben ansteigende Leiste aufweisen, aufgezogen und befüllt werden. Bei dieser Vorrichtung berühren sich jedoch Kuvert und Kuvertinhalt bereits während des Einschiebens des Inhalts. Weicht der Inhalt von einer üblichen Blattform ab oder ist das Blatt oder/und Kuvert verzogen, kann es dabei zu einer Beschädigung des Kuverts oder des Inhalts kommen.From the EP 2 756 964 A1 an enveloping device is known in which an envelope is pulled up and filled on guide blades, each of which has a ledge that initially rises upwards from the free end. In this device, however, the envelope and the contents of the envelope are already touching while the contents are being pushed in. If the content deviates from a normal sheet shape or if the sheet and/or envelope is warped, the envelope or the content may be damaged.

Aus der EP 2 261 055 A2 ist eine Kuvertiervorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt.From the EP 2 261 055 A2 an inserting device according to the preamble of claim 1 is known.

Es ist eine Aufgabe der vorliegenden Erfindung, die Nachteile des Standes der Technik zu vermeiden und eine Packtasche zu schaffen, mit welcher die Packgeschwindigkeit auf unterschiedlichen Kuvertiervorrichtungen weiter erhöht werden kann, bspw. auf 30'000 bis 40'000 Verpackungen pro Stunde. Im Weiteren ist es eine Aufgabe der Erfindung, eine Packtasche zu schaffen, die während des Kuvertiervorgangs nicht bewegt werden muss, um störende Schwingungen zu vermeiden. Schliesslich ist es auch Aufgabe der Erfindung, eine Packtasche für unterschiedliche Kuvertzuschnitte und/oder Kuvertinhalte bereitzustellen. Des Weiteren sollen auch Kuverts, die durch mindere Qualität oder schlechte Lagerung wellig geworden sind, zuverlässig verarbeitet werden, was der Stand der Technik nicht erlaubt.It is an object of the present invention to avoid the disadvantages of the prior art and to create a packing case with which the packing speed on different enveloping devices can be further increased, for example to 30,000 to 40,000 packs per hour. Furthermore, it is an object of the invention to create a pannier that does not have to be moved during the enveloping process in order to avoid disruptive vibrations. Finally, it is also the object of the invention to provide a packing bag for different envelope blanks and/or envelope contents. Furthermore, envelopes that have become wavy due to poor quality or poor storage should also be processed reliably, which the state of the art does not allow.

Eine Packtasche, die die gestellten Aufgaben erfüllt und die Nachteile des Standes der Technik vermeidet, wird in Anspruch 1, ein entsprechendes Verfahren in Anspruch 16 offenbart. Weitere bevorzugte Ausführungsformen finden sich in den Unteransprüchen.Claim 1 discloses a pannier that fulfills the stated objectives and avoids the disadvantages of the prior art, and a corresponding method is disclosed in claim 16 . Further preferred embodiments can be found in the dependent claims.

Eine erfindungsgemässe Packtasche ist für eine Kuvertiervorrichtung geeignet, die zum Einschieben eines Kuvertinhalts in ein Kuvert ausgelegt ist und beispielsweise eine Halterung für leere Kuverts, einen Klappenöffner zum Öffnen der Kuvertklappen, Transportorgane für den Transport der Kuverts von der Halterung zur Packtasche, auf der die Kuverts befüllt werden, eine Zuführeinrichtung zum Zuführen des Kuvertinhalts zu der und in die Packtasche, sowie Abtransportorgane zum Weiterbefördern des befüllten Kuverts, aufweist. Eine solche Kuvertiervorrichtung kann dabei als eine Maschine oder aus mehreren separaten Modulen aufgebaut sein, die erst nach der fertigen Montage wie beschrieben zusammenwirken.A packing bag according to the invention is suitable for an enveloping device which is designed to insert the contents of an envelope into an envelope and, for example, has a holder for empty envelopes, a flap opener for opening the envelope flaps, transport elements for transporting the envelopes from the holder to the packing bag on which the envelopes are filled, has a feed device for feeding the envelope contents to and into the packing pocket, as well as removal organs for conveying the filled envelope onward. Such an enveloping device can be constructed as a machine or from a number of separate modules, which interact as described only after the assembly is complete.

Dabei weist die Packtasche bezüglich einer Transportrichtung der Kuverts eine Mittellinie M in einer Klappenführungsebene K, sowie mehrere zur Mittellinie M parallel, mit der jeweiligen Klappenführung in der Klappenführungsebene K angeordnete Lamellen auf. Dabei wird die Klappenführungsseite bevorzugt im Wesentlichen horizontal gewählt womit die Ebene K bevorzugt im Wesentlichen mit der Horizontalebene identisch ist.The pannier has a center line M in a flap guide plane K, as well as several lamellae arranged parallel to the center line M with the respective flap guide in the flap guide plane K with respect to a transport direction of the envelopes. The flap guide side is preferably selected to be essentially horizontal, with the plane K preferably being essentially identical to the horizontal plane.

Zumindest einer oder mehreren Lamellen ist dabei eine, von der jeweiligen Klappenführung beabstandete Blattführung zugeordnet. Die Blattführung ist dabei, um unterschiedlich dicke Kuvertinhalte besser zu führen, zumindest in einem bezüglich der Kuvertzufuhr vorderen Bereich der Packtasche oder auch für die gesamte Blattführung zur Klappenführung, bzw. zur Ebenen K federnd ausgebildet. Durch diese Anordnung ist auch der Packraum definiert, in dem der Kuvertinhalt so geführt wird, dass er das Kuvert nicht berührt.At least one or more slats is assigned a leaf guide spaced apart from the respective flap guide. The sheet guide is included in order to better guide envelope contents of different thicknesses, at least in a front area of the pannier with respect to the envelope feed or also for the entire sheet guide to the flap guide, or to levels K resilient. This arrangement also defines the packing space, in which the contents of the envelope are guided in such a way that they do not touch the envelope.

Dabei wird die Federwirkung der Blattführung vorteilhafterweise so eingestellt, dass eine Zufuhrgeschwindigkeit des Kuvertinhalts für unterschiedlich dicke Kuvertinhalte im Wesentlichen beibehalten wird.The spring action of the sheet guide is advantageously set in such a way that a feed speed of the envelope contents is essentially maintained for envelope contents of different thicknesses.

Ist die Blattführung selbst eine Feder, wird diese dabei bevorzugt mit bis zu 10° Grad Abweichung senkrecht zur Klappenführung, bzw. zur Ebene K federnd, ausgeführt. Beispielsweise kann eine Blattführung aus federndem Material im hinteren Bereich fest mit einer Lamelle oder einer Montageschiene verbunden sein und sich dann fingerförmig bis in den vorderen Bereich der Klappenführung, insbesondere bis zur frei stehenden Vorderkante einer oder mehrerer Lamellen, schräg, insbesondere in einem flachen Winkel, bspw. zwischen 0° und 20°, dabei bevorzugt kleiner oder gleich 10°, gegen die Klappenführung gerichtet, erstrecken. Beim Einschieben des Kuvertinhalts, das zusätzlich durch eine schräge Ebene an Blattführung und/oder Lamelle unterstützt werden kann, ist der Kuvertinhalt durch die fingerartig ausgebildete Feder der Blattführung gestützt, wodurch eine vorzeitige Berührung des Kuverts verhindert wird. Dadurch wird auch die Verwendung und zuverlässige Verarbeitung von Kuverts einer schlechteren Qualität, wie beispielsweise oben angeführt wellige oder sonst verzogene Kuverts, möglich.If the blade guide itself is a spring, this is preferably designed to be resilient with a deviation of up to 10° perpendicular to the flap guide or to plane K. For example, a leaf guide made of resilient material can be firmly connected to a slat or a mounting rail in the rear area and then extend finger-like up to the front area of the flap guide, in particular up to the free-standing front edge of one or more slats, at an angle, in particular at a flat angle, for example between 0° and 20°, preferably less than or equal to 10°, directed towards the flap guide. When the contents of the envelope are pushed in, which can also be supported by an inclined plane on the sheet guide and/or lamella, the contents of the envelope are supported by the finger-like spring of the sheet guide, which prevents premature contact with the envelope. This also enables the use and reliable processing of envelopes of poorer quality, such as envelopes that are wavy or otherwise warped as mentioned above.

Bei dicken Kuvertinhalten verhindert diese Feder zudem, dass das Kuvert vorzeitig ausgeschoben wird. Dadurch kann auch die mechanische Belastung beim Einschieben des Kuvertinhalts für das geöffnete Kuvert herabgesetzt und zu starke Deformierung oder gar ein Einreissen vermieden werden.In the case of thick envelope contents, this spring also prevents the envelope from being ejected prematurely. As a result, the mechanical stress when pushing in the envelope contents for the opened envelope can be reduced and excessive deformation or even tearing can be avoided.

Die Blattführung kann so ausgeführt werden, dass sie im vorderen Bereich der Lamelle, insbesondere im unmittelbaren Bereich der oder an der Vorderkante der Packtasche, die Innenseite der Klappenführung berührt.The leaf guide can be designed in such a way that it touches the inside of the flap guide in the front area of the slat, in particular in the immediate area or on the front edge of the pannier.

Weitere Alternativen, wie bspw. eine durch eine oder mehrere Federn ihrerseits angedrückte Blattführung, eine durch gefederte Scharniere angedrückte Blattführung etc. können ebenso verwendet werden.Other alternatives, such as a blade guide itself biased by one or more springs, a blade guide biased by spring-loaded hinges, etc., may also be used.

Durch die Federwirkung wird das Kuvert aufgespannt, so dass zum einen Kuvertinhalte verschiedener Dicke verarbeitet werden können und zum anderen das Kuvert zurückgehalten oder gebremst wird, so dass der Inhalt mit dem Kuvert erst nach dem Abschluss des Einschiebevorgangs weiterbefördert und das Kuvert nicht schon während des Einschiebevorgangs von der Packtasche geschoben wird.The spring action stretches the envelope so that envelope contents of different thicknesses can be processed and the envelope is held back or slowed down so that the contents with the envelope are only transported on after the insertion process has been completed and the envelope not during the insertion process is pushed from the pannier.

Die Lamellen sind dabei bevorzugt voneinander getrennt an der Kuvertiervorrichtung oder einer Montageschiene angeordnet, wobei zusätzlich Mittel zum Verschieben der bezüglich der Mittellinie M äusseren Seitenlamellen, einschliesslich der diesen zugeordneten Blattführungen vorgesehen sind, um diese im Wesentlichen senkrecht zur Mittellinie M und parallel gegen- oder voneinander zu verschieben. Insbesondere für die Verarbeitung von breiteren Kuvert- bzw. Kuvertinhaltsformaten ist es vorteilhaft, wenn zwischen den äusseren Lamellen zumindest eine innere Lamelle ortsfest vorgesehen ist. Die äusseren Lamellen, auch Seitenlamellen genannt, können dabei als Winkel oder zumindest teilweise als U-Profil mit nach aussen gerichteter Basis ausgebildet sein, so dass der Kuvertinhalt an beiden Seiten durch das U-Profil geschützt oder/und geführt wird.The lamellae are preferably arranged separately from one another on the enveloping device or a mounting rail, with additional means for shifting the outer side lamellae with respect to the center line M, including the sheet guides assigned to them, being provided around them essentially perpendicularly to the center line M and parallel to or from each other to move. In particular for the processing of With wider envelope or envelope content formats, it is advantageous if at least one inner lamella is provided in a stationary manner between the outer lamellae. The outer lamellae, also called side lamellae, can be designed as an angle or at least partially as a U-profile with an outward-facing base, so that the contents of the envelope are protected and/or guided by the U-profile on both sides.

Die Stellmittel zum Verschieben der Seitenlamellen können elektrische oder mechanische Mittel, bevorzugt eine Stellspindel umfassen. Zur Führung des Kuvertinhalts sind die äusseren Lamellen auf der jeweils äusseren Seitenfläche vorteilhafterweise geschlossen. Dem hingegen sind die beiden Seitenflächen der zumindest einen inneren Lamelle offen ausgeführt.The adjusting means for moving the side slats can include electrical or mechanical means, preferably an adjusting spindle. In order to guide the contents of the envelope, the outer lamellae are advantageously closed on the respective outer side surface. On the other hand, the two side faces of the at least one inner lamella are designed to be open.

In weiteren Ausführungsform ist zumindest den zwei äusseren Lamellen jeweils eine Blattführung zugeordnet. Alternativ kann zumindest einer inneren Lamelle, dabei bevorzugt zumindest einer mittleren Lamelle oder jeweils allen Lamellen eine Blattführung zugeordnet sein. Bei einer Ausführung mit einer der mittleren Lamelle zugeordneten Blattführung kann diese sich seitlich der Mittelline M hinaus bis in den Bereich benachbarter oder/und in den Bereich der äusseren Lamellen erstreckend ausgeführt sein.In a further embodiment, at least the two outer slats are each assigned a blade guide. Alternatively, a blade guide can be assigned to at least one inner slat, preferably at least one middle slat, or to all slats. In an embodiment with a blade guide assigned to the middle slat, this can be designed to extend laterally of the center line M out into the area of adjacent slats and/or into the area of the outer slats.

Bei einem erfindungsgemässen Verfahren zum Befüllen einer Packtasche, insbesondere einer wie oben beschriebenen Packtasche, wird ein Kuvert mit geöffneter Kuvertklappe voran zu der Packtasche transportiert, und ein Kuvertinhalt mittels einer Zuführeinrichtung zu der Packtasche zugeführt. Das dabei befüllte Kuvert wird anschliessend durch Abtransportorgane weiterbefördert.In a method according to the invention for filling a packing bag, in particular a packing bag as described above, an envelope with the envelope flap open is transported first to the packing bag, and the contents of the envelope fed to the pack bag by means of a feed device. The envelope filled in the process is then conveyed onward by removal organs.

Die Kuverts werden dabei zunächst, beispielsweise durch eine bewegliche Niederhalterolle oder eine trichterartige Anordnung zur Führung der Kuverts in Richtung auf die Packtasche ausgerichtet.The envelopes are initially aligned, for example, by a movable hold-down roller or a funnel-like arrangement for guiding the envelopes in the direction of the packing bag.

Beim anschliessenden Aufziehen des Kuverts auf die Packtasche wird dieses zunächst durch Transport- und Gegenrollen auf die Packtasche aufgestossen und bevorzugt, um ein Ausknicken zu verhindern, spätestens ab dem Zeitpunkt, wo die Rückkante des Kuverts nicht mehr im Eingriff zwischen Transport- und Gegenrollen ist von einer oder mehreren Aufzugsrollen auf die Packtasche aufgezogen, bis der Kuvertboden an der Vorderkante der Packtasche ansteht.When the envelope is then pulled onto the packing bag, it is initially pushed onto the packing bag by transport and counter rollers and, in order to prevent buckling, this is preferably done at the latest from the point in time when the rear edge of the envelope is no longer engaged between the transport and counter rollers one or more winding rollers onto the pannier until the bottom of the envelope is in contact with the front edge of the pannier.

Um die Öffnung des Kuverts zusätzlich zu unterstützen und damit das Aufziehen auf die Packtasche zu erleichtern, können dabei zwischen den zur Packtasche unmittelbar benachbarten Transportmitteln, beispielsweise einer Transportrolle oder einem Trichter, und einem Aufziehmittel, beispielsweise einer Aufziehrolle, die Klappenführungsebene seitlich begrenzende vorzugsweise verstellbare Konusse vorgesehen sein.In order to additionally support the opening of the envelope and thus make it easier to pull it onto the packing bag, preferably adjustable cones laterally delimiting the flap guide plane can be placed between the transport means immediately adjacent to the packing bag, for example a transport roller or a funnel, and a winding means, for example a winding roller be provided.

Die Zuführung der Kuverts kann dabei von oben oder von unten erfolgen. Dabei kann auch ein Transportwinkel (Wt), zwischen zugeführtem Kuvert und Klappenführung, während des Aufziehens des Kuverts auf die Packtasche variiert werden um eine Öffnung des Kuverts zu erleichtern.The envelopes can be fed in from above or below. A transport angle (Wt) between the supplied envelope and the flap guide can also be varied while the envelope is being pulled onto the packing pocket in order to facilitate opening of the envelope.

Zur Zuführung des Kuvertinhalts kann die Zuführeinrichtung auf Zahn- oder Treibriemen, oder auf Ketten befestigte Finger umfassen. Diese können beispielsweise durch Schlitze in der Packtasche von einer Seite über die andere Seite der Zuführebene hinausragend geführt sein. Alternativ können die Transportfinger auch zwischen den wie oben beschriebenen Lamellen einer segmentierten Packtasche geführt werden.To feed the contents of the envelope, the feed device can comprise toothed belts or drive belts, or fingers fastened on chains. These can be guided, for example, through slits in the pannier from one side to the other side of the feed plane. Alternatively, the transport fingers can also be guided between the slats of a segmented pannier as described above.

Während des vorteilhaft gleichzeitig mit dem Aufstossen eingeleiteten Befüllen wird der Kuvertinhalt in der Packtasche geführt, die mehrere zur Mittellinie M parallel, mit einer Klappenführung in einer Ebene K angeordnete Lamellen umfasst. Der Kuvertinhalt wird dabei durch eine Blattführung, zumindest in einem, bezüglich der Kuvertzufuhr vorderen Bereich, zur Klappenführung federnd angedrückt, so dass der Kuvertinhalt das Kuvert erst im Bereich einer Vorderkante der Packtasche berührt.During the filling, which is advantageously initiated at the same time as the burping, the contents of the envelope are guided in the packing pocket, which comprises a plurality of lamellae arranged parallel to the center line M in a plane K with a flap guide. The contents of the envelope are resiliently pressed by a sheet guide, at least in a front area with respect to the envelope feed, to the flap guide, so that the contents of the envelope touch the envelope only in the area of a front edge of the packing pocket.

Vorteilhafterweise wird dabei der Kuvertinhalt zumindest durch zwei, jeweils äusseren Lamellen zugeordneten Blattführungen angedrückt. Zusätzlich oder alternativ auch allein kann das Andrücken durch eine einer inneren Lamelle zugeordneten Blattführung erfolgen. Diese kann, insbesondere, wenn sie die einzige Blattführung der Packtasche ist auch breiter als die zugehörige bspw. mittlere Lamelle ausgeführt sein.Advantageously, the contents of the envelope are pressed on at least by two sheet guides each assigned to the outer lamellae. In addition or as an alternative, the pressing can also be carried out by a sheet guide assigned to an inner lamella. This can also be made wider than the associated, for example, middle slat, especially if it is the only leaf guide of the pannier.

Des Weiteren kann der Kuvertinhalt zusätzlich durch geschlossene äussere Seitenflächen der äusseren, beispielsweise zumindest teilweise als U-Profil ausgebildeten, Lamellen geführt werden.Furthermore, the contents of the envelope can also be guided through closed outer side surfaces of the outer lamellae, which are at least partially designed as a U-profile, for example.

Von der Packtasche in Abtransportrichtung des Kuverts (downstream) sind Abtransportorgane, bspw. Abtransportrollen und ein odere mehrere Segmente, vorgesehen, um das gefüllte Kuvert von der Packtasche weiterzubefördern. Der Abtransportwinkel (Wa) von der Vorderkante der Packtasche wird dabei vorteilhaft flach nach unten gerichtet, um ein Herausrutschen des Kuvertinhalts während des Abtransports zu verhindern.From the packing pocket in the removal direction of the envelope (downstream), removal elements, for example removal rollers and one or more segments, are provided in order to transport the filled envelope from the packing pocket. The transport angle (Wa) from the front edge of the pannier is advantageously directed flat downwards in order to prevent the contents of the envelope from slipping out during transport.

Bei einem weiteren erfindungsgemässen Verfahren zum Befüllen einer Packtasche wird beispielsweise zunächst in bekannter Weise die Klappe des zu einer Kuvertentnahmeöffnung einer Kuverhalterung am nächsten gelegenen Kuverts eines in der Halterung abgelegten Kuverstapels mit einem Klappenöffner geöffnet. Anschliessend wird das Kuvert durch Transportorgane von der Halterung zu einer Packtasche transportiert, auf der die Kuverts befüllt werden. Der Kuvertinhalt wird dabei mittels einer Zuführeinrichtung zu der Packtasche zugeführt und anschliessend das befüllte Kuvert durch Abtransportorgane weiterbefördert.In a further method according to the invention for filling a packing bag, for example, the flap of the envelope closest to an envelope removal opening of an envelope holder of an envelope stack placed in the holder is opened with a flap opener in a known manner. The envelope is then transported by transport elements from the holder to a packing bag, on which the envelopes are filled. The contents of the envelope are fed to the packing pocket by means of a feed device and the filled envelope is then conveyed onward by removal organs.

Die Kuverts werden dabei beispielsweise durch eine bewegliche Niederhalterolle oder eine trichterartige Anordnung zur Führung der Kuverts in Richtung auf die Packtasche ausgerichtet. Gleichzeitig wird durch zumindest ein Aufziehmittel, beispielsweise eine Aufziehrolle, das Kuvert zumindest teilweise, bevorzugt aber vollständig auf die Packtasche aufgezogen, wobei das Aufziehmittel, beispielsweise Aufziehroile(n) zumindest zeitweise, bspw. periodisch, mit der Packtasche zusammenwirkt. Dabei werden des Weiteren Mittel zur Synchronisierung der Bewegung der Niederhalterolle oder des Trichters mit dem Aufziehmittel verwendet, die diese von einer ersten Position beim Empfangen der Kuvertklappe durch den Trichter, in eine zweite Position nach dem Aufsetzen der Kuvertklappe auf der Klappenführung bewegen. Dadurch wird ein Transportwinkel (Wt), zwischen zugeführtem Kuvert und Klappenführung, während des Aufziehens des Kuverts auf die Packtasche variiert um eine Öffnung des Kuverts zu erleichtern.The envelopes are aligned, for example, by a movable hold-down roller or a funnel-like arrangement for guiding the envelopes in the direction of the packing bag. At the same time, the envelope is pulled at least partially, but preferably completely, onto the packing bag by at least one winding means, for example a winding roller, with the winding means, for example winding roller(s) interacting with the packing bag at least temporarily, e.g. periodically. be there further employs means for synchronizing the movement of the hold down roller or hopper with the opening means, moving it from a first position upon receipt of the envelope flap by the hopper to a second position after the envelope flap has been seated on the flap guide. As a result, a transport angle (Wt) between the supplied envelope and the flap guide varies while the envelope is being pulled onto the packing pocket in order to facilitate opening of the envelope.

Anschliessend werden die Kuverts, bspw. wie oben erwähnt, abtransportiert.The envelopes are then transported away, for example as mentioned above.

Das Prinzip der vorliegenden Erfindung sowie verschiedene Beispiele möglicher Ausführungsformen werden im Folgenden anhand der Figuren besprochen.The principle of the present invention and various examples of possible embodiments are discussed below with reference to the figures.

Fig. 1 zeigt ein Schema einer Kuvertiervorrichtung mit Kuvertzufuhr von oben. Dabei werden die in einer Halterung 6 für leere Kuverts, mit der Klappe in Transportrichtung nach unten abgelegten Kuverts nach Öffnen durch einen Klappenöffner 7, der beispielsweise eine Öffnerklaue 25 umfasst, mit der geöffneten Klappe nach vorne von zumindest einem Transportorgan 8 in Richtung der Packtasche 9 transportiert. Zum Aufziehen auf die Packtasche wird das Kuvert 2 durch den Trichter 12 auf die Packtasche 9 ausgerichtet. Trichter 12 und Öffnungskonusse 27 helfen beim Öffnen des Kuverts 2, um dieses leichter auf die Packtasche aufzuziehen. Nach Aufziehen des Kuverts wird dieses mit dem über die Zuführeinrichtung 10 zugeführten Kuvertinhalt 5 befüllt. Anschliessend wird das Kuvert vorzugsweise ohne Unterbrechung der Bewegung des Kuvertinhalts 5, durch zumindest einen Einschubfinger 26, der Kuvert und Inhalt hier bis in den Bereich des Trichters führt, an die Abtransportorgane 11 übergeben und abtransportiert. 1 Figure 12 shows a schematic of an inserter with top feed envelopes. In this case, in a holder 6 for empty envelopes, with the flap in the transport direction envelopes deposited downward after opening by a flap opener 7, which comprises, for example, an opening claw 25, are transported with the open flap forwards by at least one transport element 8 in the direction of the packing bag 9. The envelope 2 is aligned with the packing bag 9 by the funnel 12 in order to be pulled onto the packing bag. Funnel 12 and opening cones 27 help to open the envelope 2 in order to pull it more easily onto the pannier. After the envelope has been pulled open, it is filled with the envelope contents 5 supplied via the feed device 10 . The envelope is then transferred to the removal organs 11 and transported away, preferably without interrupting the movement of the envelope contents 5, by at least one insertion finger 26, which guides the envelope and contents here into the area of the funnel.

Fig. 2 zeigt eine Funktionsskizze des Aufziehens des Kuverts am Beispiel einer von oben zuführenden Kuvertiervorrichtung. Nachdem das Kuvert 2 mit der Kuvertklappe 3 voran, zwischen einem gegenläufig drehenden Rollenpaar, hier einer angetriebenen Transportrolle 20 und der gegen die Transportrolle 20 angedrückten Gegenrolle 21, durch einen Trichter 12 in einen Transportwinkel (Wt), der Klappenführungseite der Packtasche 9 zugeführt wurde, wird die Klappenseite des Kuverts auf der Klappenführung weitergeschoben, bis sie von einer hier absenkbaren Aufziehrolle 14, wie dargestellt erfasst und auf die Packtasche aufgezogen wird. Währenddessen kann der Transportwinkel Wt und Transportebene T durch ein zustellen des Trichters in Richtung der Ebene K, beispielsweise wie dargestellt zu Wt" bzw. WT und T" verschoben werden. 2 shows a functional sketch of the opening of the envelope using the example of an enveloping device fed in from above. After the envelope 2 has been fed with the envelope flap 3 first, between a counter-rotating pair of rollers, here a driven transport roller 20 and the counter roller 21 pressed against the transport roller 20, through a funnel 12 into a transport angle (Wt), the flap guide side of the packing bag 9, the flap side of the envelope is pushed further on the flap guide until it is caught by a pull-up roller 14 that can be lowered here, as shown, and pulled onto the packing bag. Meanwhile, the transport angle Wt and transport plane T can be adjusted by one of the funnel in the direction of the plane K, for example, as shown, to Wt" or WT and T".

Ist die Klappenführungsseite der Klappenführung völlig planar, wird diese vollständig von der Ebene K umfasst. Üblicherweise wird aber die Oberfläche der Klappenführungsseite auch durch Rippen oder andere Elemente auf den voneinander beabstandeten Lamellen gebildet. Diese Elemente können die Ebene K auch durchstossen. Beispielsweise können auf der Packtasche von einem Bereich in der Nähe der oder an der Vorderkante der Packtasche, wie in Figur 3 dargestellt, zumindest in einem Teilbereich schräg nach hinten ansteigende Rippen 33, die die Vorderkante der Kuvertklappe und somit die ganze Klappe anheben vorgesehen sein, damit der Finger der Zuführeinrichtung unter dieser hindurchfahren kann, während er selbst über die Klappenführungsebene K der Packtasche reicht. Der Finger schaut dabei oben knapp aus der Packtaschenebene heraus, damit kein Dokument in der Packtasche verloren geht. Dabei sind Klappenführungsseite bzw. Ebene K bevorzugt im Wesentlichen horizontal ausgerichtet.If the flap guide side of the flap guide is completely planar, then the plane K completely encompasses it. Usually, however, the surface of the flap guide side is also formed by ribs or other elements on the spaced lamellae. These elements can also break through level K. For example, on the pannier from an area near or at the front edge of the pannier, as in figure 3 shown, at least in a partial area, ribs 33 rising diagonally to the rear can be provided, which lift the front edge of the envelope flap and thus the entire flap, so that the finger of the feed device can pass under it while it itself reaches over the flap guide level K of the packing bag. The finger sticks out just above the pannier level so that no document gets lost in the pannier. In this case, the flap guide side or plane K are preferably aligned essentially horizontally.

Durch das Zustellen des Trichters 12 während des Durchlaufs des Kuverts, kann dabei eine leichte Öffnung des Kuverts 2 ermöglicht werden, die durch hier strichliert dargestellte Konusse 27, die in einem Bereich seitlich der Vorderkante der Packtasche montiert sind, weiter unterstützt werden kann. Vorteilhafterweise wird die Bewegung des Trichters von einer ersten Position zu einer zweiten Position unmittelbar vor oder beim Aufsetzen der Klappenspitze auf die Klappenführungsseite, bis zum Passieren der vordersten Kante der Packtasche 9 durch den Klappenfalz 4, also im Bereich ca. einer Klappenlänge 1 vorgenommen.By adjusting the funnel 12 while the envelope is passing through, an easy opening of the envelope 2 can be made possible, which can be further supported by the cones 27 shown here in dashed lines, which are mounted in an area to the side of the front edge of the packing bag. Advantageously, movement of the funnel from a first position to a second position occurs immediately prior to or at the time of valve tip impaction the flap guide side, until the front edge of the pannier 9 is passed through the flap fold 4, ie in the area of approximately one flap length 1.

Beim Aufziehen des Kuverts 2, bspw. mit Hilfe von synchron zum Kuvertlauf abgesenkten Aufziehrollen 14, wird der Kuvertinhalt 5 durch die Zuführeinrichtung 10, die bspw. zumindest einen, auf einem Zahnriemen oder einer Kette befestigten Finger 26 sowie einen Zuführantrieb 32 umfasst, durch die Packtasche 9 in das Kuvert 2 geschoben. Durch die im Wesentlichen geschlossene Ausführung der erfindungsgemässen Packtasche, wird dabei eine Berührung des Kuvertinhalts 5 mit dem Kuvert 2 verhindert. Erst beim Erreichen des Kuvertbodens im Bereich der Vorderkante der Packtasche kommt es dabei erstmals zu einem Kontakt zwischen Kuvertinhalt und Kuvert, wobei der Kuvertinhalt das Kuvert von der Packtasche wegschiebt. Anschliessend wird, nach Abheben der Aufziehrolle 14 vom aufgezogenen, nun gepackten Kuvert, das Kuvert durch Finger 26 in Richtung der Abtransportorgane, bspw. des mit der Transportrolle 20 und/oder gesonderten Abtransportrolle 22 zusammenwirkenden Segments 23 bewegt.When the envelope 2 is being opened, e.g Pannier 9 pushed into envelope 2. The essentially closed design of the packing bag according to the invention prevents the contents 5 of the envelope from coming into contact with the envelope 2 . Only when the bottom of the envelope is reached in the area of the front edge of the bag does the contents of the envelope and the envelope come into contact for the first time, with the contents of the envelope pushing the envelope away from the bag. Then, after lifting the pull-up roller 14 from the pulled-up, now packed envelope, the envelope is moved by fingers 26 in the direction of the transport organs, e.g.

Alternativ kann dabei die Aufziehrolle 14 auch zunächst entgegengesetzt zur Aufzugsrichtung, in Abtransportrichtung betrieben werden um das Kuvert auf die Geschwindigkeit des kontinuierlich zugeführten Kuvertinhalts zu beschleunigen, wodurch auch bspw. besonders dünne, oder empfindliche Kuverts befüllt werden können ohne die Geschwindigkeit des durchlaufenden Kuvertinhalts in der Packtasche zu verringern bzw. ohne diesen zu stark oder überhaupt abbremsen zu müssen. Durch die Abtransportorgane 11, 20, 23 wird das Kuvert, bevorzugt, um ein Heraus- oder Verrutschen des Kuvertinhaltes 5 zu vermeiden, in einem nach unten gerichteten flachen Abtransportwinkel Wa, weiterbefördert.Alternatively, the pull-up roller 14 can also initially be operated in the opposite direction to the winding-up direction, in the transport direction, in order to accelerate the envelope to the speed of the continuously supplied envelope contents, which means that, for example, particularly thin or sensitive envelopes can also be filled without the speed of the envelope contents passing through in the Pannier to reduce or without having to brake it too hard or at all. The envelope is conveyed further by the removal organs 11, 20, 23, preferably in order to prevent the envelope contents 5 from slipping out or slipping, at a downwardly flat removal angle Wa.

Ein solcher nach unten gerichteter Abtransportwinkel ist auch bei einer Kuvertiervorrichtung mit einer Kuvertzufuhr von unten vorteilhaft, bei der die Packtasche 9 vorteilhaft umgekehrt, daher mit der äusseren Klappenführungsseite der Klappenführung 13 nach unten gerichtet, montiert ist. Das Kuvert kann ebenfalls umgekehrt (Klappe unten) zugeführt werden.Such a downward transport angle is also advantageous in an enveloping device with an envelope feed from below, in which the packing pocket 9 is advantageously mounted upside down, ie with the outer flap guide side of the flap guide 13 pointing downwards. The envelope can also be fed in upside down (flap down).

In Fig. 3 ist eine erfindungsgemässe verstellbare Packtasche abgebildet, die mit ganz unterschiedlichen Kuvertiervorrichtungen verwendet werden kann, wenn diese bezüglich der Kuvertzuschnitte und bezüglich Packmasse, insbesondere bezüglich der Dicke des Kuverinhalts, flexibel gestaltet werden sollen. Gemäss dem dort dargestellten Ausführungsbeispiel sind drei sogenannte Lamellen 28 an bzw. unter einer Montageschiene 15, hier bevorzugt einer Verstellschiene 35, montiert. Während die hier eine innere Lamelle 28" ortsfest an der Montage- oder der Verstellschiene befestigt ist, können die äusseren Lamellen 28' quer zur Transport- bzw. Abtransportrichtung bewegt werden, um so die Packtasche 9 optimal auf unterschiedliche Kuvertbreiten einstellen zu können. Die Einstellung der Breite wird im vorliegenden Beispiel mit einer handbetriebenen Stellspindel 31 vorgenommen, dies kann jedoch auch automatisch, z.B. elektrisch angetrieben, vorgesehen werden. Zum flexiblen Befestigen einer solchen Packtasche 9 an der Kuvertiervorrichtung 1 ist hier ein Montageanschlag 36 vorgesehen.In 3 an adjustable packing bag according to the invention is shown, which can be used with very different enveloping devices if these are to be designed flexibly with regard to the envelope blanks and with regard to the packing mass, in particular with regard to the thickness of the envelope contents. According to the exemplary embodiment shown there, three so-called slats 28 are mounted on or under a mounting rail 15, here preferably an adjustment rail 35. While the one inner lamella 28" is permanently attached to the mounting or adjustment rail, the outer lamellas 28' can be moved transversely to the transport or transport direction in order to be able to optimally adjust the packing bag 9 to different envelope widths. The setting the width is made in the present example with a hand-operated adjusting spindle 31, this can however, can also be provided automatically, for example electrically driven. A mounting stop 36 is provided here for the flexible attachment of such a pack bag 9 to the enveloping device 1 .

Fig. 4 zeigt eine Rückansicht der in Fig. 3 dargestellten Packtasche 9. Dabei sind zusätzlich noch Hilfsflächen 34 zu erkennen, die den inneren Führungsflächen der einzelnen Lamellen in Zuführrichtung des Kuvertinhalts vorgelagert angeordnet sind, um ein leichteres Einschieben des Inhalts in die Packtasche 9 zu ermöglichen. Um ein möglichst sicheres Aufziehen des Kuverts 2 auf die Packtasche 9 sicherzustellen, können dabei die Seitenlamellen 28' im Bereich der in Richtung der Transport-, Abtransportebene gewandten frei stehenden Vorderkante 53, wie in Fig. 3 dargestellt, nach innen, in Richtung der feststehenden inneren Lamelle, bzw. der Mittellinie M, ragend ausgebildet sein. Die äusseren Seitenflächen der Lamellen 28' sind dabei zumindest teilweise geschlossen, um den Kuvertinhalt 5 seitlich zu führen und ein Berühren des Kuvertinhalts mit dem Kuvert vor dem Abschluss des Einschiebevorgangs zu verhindern. 4 shows a rear view of the in 3 illustrated pannier 9. Auxiliary surfaces 34 can also be seen, which are arranged in front of the inner guide surfaces of the individual lamellae in the feed direction of the envelope contents in order to enable easier insertion of the contents into the pannier 9. In order to ensure that the envelope 2 is pulled onto the packing bag 9 as securely as possible, the side lamellae 28' in the area of the free-standing front edge 53 facing in the direction of the transport and removal planes, as shown in 3 shown, inwardly, in the direction of the fixed inner lamella, or the center line M, be formed projecting. The outer side surfaces of the lamellae 28' are at least partially closed in order to guide the envelope contents 5 laterally and to prevent the envelope contents from touching the envelope before the end of the insertion process.

Fig. 5 zeigt beispielhaft die Seitenansicht einer äusseren Lamelle 28' von innen gesehen. Klappenführung 13, wie hier dargestellt oben, und Blattführung 30 unten, sind beide mit einer Hilfsfläche 34 in Richtung der Zuführeinrichtung 10 versehen. Die Seitenlamelle 28' umfasst einen Lamellenfuss 37, der bspw. mit der Klappenführung 13 als einstückiger Winkel hergestellt sein kann, um die Stabilität der Packtasche zu erhöhen. figure 5 shows an example of the side view of an outer lamella 28 'seen from the inside. Flap guide 13, as shown here at the top, and sheet guide 30 at the bottom, are both provided with an auxiliary surface 34 in the direction of the feeder 10. The side slat 28' includes a slat foot 37, which can be made as a one-piece bracket with the flap guide 13, for example, in order to increase the stability of the pannier.

Am Lamellenfuss 37 kann die Blattführung 30 im hinteren Bereich mit einem Federanschlug 38 befestigt sein. Die aus einem federnden Material hergestellte Blattführung 30 ist dabei in einem schrägen Winkel zur Innenfläche der Klappenführung angestellt, so dass sie im vorderen Bereich in unmittelbarer Nähe der Klappenführung endet oder sogar an dieser anliegt. Erst durch Einschieben des Kuvertinhalts wird die Blattführung 30 nach unten gedrückt und gibt den Weg ins Kuvert bzw. in Abtransportrichtung frei. Dadurch können auch bezüglich ihrer Dicke unterschiedliche Kuvertinhalte sicher mit derselben Geschwindigkeit zugeführt werden. Die maximale Dicke des Kuvertinhalts wird in diesem Fall durch einen Abstand z, im hinteren Bereich, zwischen den inneren Führungsflächen der Klappenführung 13 und der Blattführungen 30 bestimmt.The blade guide 30 can be fastened in the rear area to the lamellar foot 37 with a spring stop 38 . The sheet guide 30 made of a resilient material is set at an oblique angle to the inner surface of the flap guide, so that it ends in the front area in the immediate vicinity of the flap guide or even rests against it. Only when the contents of the envelope are pushed in is the sheet guide 30 pressed down and clears the way into the envelope or in the transport direction. As a result, envelope contents that are different in terms of their thickness can be reliably fed in at the same speed. In this case, the maximum thickness of the envelope contents is determined by a distance z, in the rear region, between the inner guide surfaces of the flap guide 13 and the sheet guides 30.

Alternativ kann die Lamelle 28' zumindest teilweise als U-Profil mit nach aussen gerichteter Basis ausgebildet sein, so dass der Kuvertinhalt von den äusseren Lamellen durch das U-Profil geführt und/oder gestützt wird. Der hier untere Teil des U-Profils kann dabei beispielsweise als gefedertes Scharnier ausgebildet sein, das den Kuvertinhalt gegen die Klappenführung anhebt.Alternatively, the lamella 28' can be designed at least partially as a U-profile with an outwardly directed base, so that the contents of the envelope are guided and/or supported by the outer lamellae through the U-profile. Here, the lower part of the U-profile can be designed, for example, as a spring-loaded hinge that lifts the contents of the envelope against the flap guide.

Der Aufbau einer inneren Lamelle 28" kann ähnlich dem der äusseren Lamelle 28' gewählt werden, wobei hier vorteilhafterweise Blattführung 30 und Klappenführung 13 separat an der Kuvertiereinrichtung oder entsprechenden Montageschienen oder Anschlägen montiert sind.The structure of an inner lamella 28" can be selected similar to that of the outer lamella 28', with the sheet guide 30 and flap guide 13 advantageously being mounted separately on the enveloping device or corresponding mounting rails or stops.

Wie bereits erwähnt, werden bei einer Kuvertiervorrichtung mit Zuführung von unten die Packtasche bzw. die Lamellen der Packtasche umgekehrt, d.h. mit der Klappenführung nach unten montiert. Die Klappenführungsebene K kann auch in diesem Fall mit der Horizontalebene identisch sein, Rippe 33 ragt von der Horizontalebene, bzw. der Oberfläche der Packtasche hier nach unten ab und verläuft zumindest in einem Teilbereich schräg ansteigend nach hinten.As already mentioned, in the case of an inserting device with feed from below, the pannier or the lamellae of the pannier reversed, ie mounted with the flap guide downwards. The flap guide plane K can also be identical to the horizontal plane in this case, rib 33 protrudes from the horizontal plane or the surface of the pannier downwards and runs at least in a partial area, rising obliquely to the rear.

Wiewohl im vorhergehenden einzelne Aspekte der Erfindung in unterschiedlichen Ausführungsbeispielen gezeigt wurden, sind die einzelne Aspekte im Rahmen des dem Fachmann geläufigen Wissens ohne weiteres miteinander kombinierbar, sofern sie sich nicht, wie vom Fachmann ohne weiteres erkennbar, gegenseitig ausschliessen. Weitere Ausführungsformen ergeben sich aus der vorliegenden Offenbarung und dem allgemeinen Wissen des Fachmanns für Kuvertier- und Verpackungsvorrichtungen.Although individual aspects of the invention have been shown in different exemplary embodiments above, the individual aspects can easily be combined with one another within the scope of the knowledge familiar to the person skilled in the art, provided they are not mutually exclusive, as the person skilled in the art can readily recognize. Further embodiments can be derived from the present disclosure and the general knowledge of the person skilled in the art of inserting and packaging devices.

Ferner können Kuverts mit bereits geöffneter Klappe zugeführt werden. Das ergibt die Möglichkeit, die Kuverts inline herzustellen, das heisst diese vorgängig aus einer Papierbahn zu falzen und zu kleben, und / oder Kuverts mit geöffneter Klappe zu bedrucken, da so bei nur einseitigem Bedrucken nach dem Schliessen der Klappe auch ein Teil der Rückseite des geschlossenen Kuverts (eben die Klappe) bedruckt ist. Dabei können dem System die Kuverts direkt mit geöffneter Klappe zugeführt werden, ohne dass die Klappe erst innerhalb der Kuvertiervorrichtung geöffnet werden muss.In addition, envelopes can be fed in with the flap already open. This makes it possible to produce the envelopes inline, i.e. to fold and glue them from a paper web beforehand, and/or to print on envelopes with the flap open, since this means that when the flap is only printed on one side, part of the back of the envelope is also visible after the flap is closed closed envelope (ie the flap) is printed. The envelopes can be fed directly into the system with the flap open, without the flap first having to be opened within the enveloping device.
