Abstract

The invention addresses the problem of substantially raising the output of an inserter. Whereas EP-A-0 504 114 to this end discloses the use of rotary members for opening the envelopes and gripping the envelope flaps, the invention proposes opening and grasping the envelope (20) in one conveying plane (13), inserting the contents (21) into the envelope in a conveying plane (12) that is stepwise offset therefrom, and situating between the two a link chain (10) with spreaders (9) which moves perpendicular to the conveying planes (12, 13), holding ready and feeding the envelopes (20) opened up by the spreaders to another station where the contents (21) are inserted into the envelopes.

Description

B E S C H R E I B U N G DESCRIPTION
KuvertiervorrichtungInserting device
Die Erfindung bezieht sich auf eine Kuvertiervorrichtung mit je einer Stapel- und Abzugseinrichtung für die Kuverts und die Kuvertinhalte sowie mit einer Anordnung zumThe invention relates to an inserting device, each with a stacking and pulling device for the envelopes and the envelope contents, and with an arrangement for
Spreizen des Kuverts und zum Einführen des Kuvertinhaltes in das gespreizte Kuvert nebst einem Förderer zum Abtransport der gefüllten Kuverts.Spreading the envelope and for inserting the envelope contents into the spread envelope together with a conveyor for removing the filled envelopes.
Bekannte Kuvertiermaschinen dieser Art besitzen eine begrenzte Leistung. Das geöffnete und vom Stapel abgezogene Kuvert muß nämlich von der einen Seite auf eine sogenannte Einpacktasche aufgezogen werden, mit der zugleich das Kuvert gespreizt wird. Von der anderen Seite her wird alsdann der Kuvertinhalt der Einpacktasche zugeführt und in das Kuvert eingeschoben. Beide Vorgänge geschehen also nacheinander und begrenzen somit die maximale Leistungsfähigkeit der Kuvertiervorrichtung.Known inserting machines of this type have a limited performance. The opened envelope, which has been removed from the stack, must be pulled from one side onto a so-called packing bag, with which the envelope is spread apart. From the other side, the envelope content is then fed into the packing bag and inserted into the envelope. Both processes therefore take place in succession and thus limit the maximum performance of the inserting device.
Durch die EP-A 0 504 114 ist die Problemstellung bekannt, die Abpackgeschwindigkeit ungefähr zu verdoppeln. Man war der Meinung, daß Hin- und Herbewegungen verschiedener Elemente bei der vorbekannten Kuvertiermaschine dafür ursächlich sein, daß die Leistung nicht gesteigert werden könne. Stattdessen wird mit der EP-A 0 504 114 vorgeschlagen, eine Leistungssteigerung dadurch herbeizuführen, daß das öffnen und Abziehen des Kuverts vom Stapel durch rotierende Elemente geschieht, die auf gleicher Achse gelagert, aber unterschiedlich angetrieben sind. Allerdings wird bei dieser Offenbarung ebenfalls mit einer Einpacktasche gearbeitet, auf welche das herangeführte Kuvert erst aufgezogen werden muß, um danach den von anderer Seite herangeführten Kuvertinhalt in das Kuvert einzuführen. Damit sind ebenfalls Stillstandszeiten vorprogrammiert, welche leistungshemmend wirken.EP-A 0 504 114 discloses the problem of roughly doubling the packaging speed. It was believed that back and forth movements of various elements in the previously known inserting machine were the reason why the performance could not be increased. Instead, EP-A 0 504 114 proposes to increase performance by opening and pulling the envelope off the stack by rotating elements which are mounted on the same axis but are driven differently. However, in this disclosure, a packing bag is also used, to which the envelope that has been brought up must first be opened in order to do so insert the envelope contents brought in from another side into the envelope. This also means that downtimes are pre-programmed, which have an effect on performance.
Der Erfindung liegt dem gegenüber die Aufgabe zugrunde, die angestrebte Leistungssteigerung dadurch herbeizuführen, daß mit mehreren Einpacktaschen gearbeitet wird, indem zu gleicher Zeit das eine Kuvert auf die eine Einpacktasche und ein anderes Kuvert an anderer Stelle mit dem Kuvertinhalt gefüllt wird, um auf diese Weise die TaktZeiten wesentlich zu reduzieren.The invention is based on the object to bring about the desired increase in performance by working with several packing bags, at the same time filling an envelope on one packing bag and another envelope elsewhere with the envelope contents, in this way to reduce the cycle times significantly.
Dieses Problem wird im Sinne der Erfindung dadurch gelöst, daß die Anordnung zum Spreizen und Bereithalten der Kuverts als eine mit mehreren SpreizorganenThis problem is solved in the sense of the invention in that the arrangement for spreading and holding the envelopes as one with several spreading members
(Einpacktaschen) ausgerüstete Gliederkette ausgebildet ist, deren Förderebene sich quer zu und zwischen den in verschiedenen Etagen befindlichen Förderebenen für die Kuverts und die Kuvertinhalte erstreckt, wobei das einzelne Spreizorgan in der 'Stillstandsphase in der einen Förderebene das geöffnete Kuvert aufnimmt und in der anderen Förderebene das erhaltene Kuvert zum Einschieben des Kuvertinhaltes bereithält.(Packing bags) equipped link chain is formed, the conveying level extends transversely to and between the conveying levels for the envelopes and the envelope contents located on different floors, the individual expansion element in the ' standstill phase in one conveying level receiving the open envelope and in the other conveying level holds the received envelope ready to insert the contents of the envelope.
Beim Gegenstand der Erfindung wird die Taktzeit also dadurch verkürzt, daß das Aufziehen des Kuverts auf das Spreizorgan (Einpacktasche) zeitgleich mit dem Einschieben des Kuvertinhaltes in ein anderes Kuvert stattfindet und daß die Zeit, die zum Zuführen bzw. Abziehen eines Kuverts benötigt wird, dazu ausgenutzt wird, die Spreizorgane von der Aufnahmestation für Kuverts in die Abgabestation zu fördern.In the subject of the invention, the cycle time is thus shortened in that the opening of the envelope onto the expansion element (packing bag) takes place at the same time as the contents of the envelope are being inserted into another envelope and that the time required for feeding or removing an envelope is added is used to promote the spreading organs from the receiving station for envelopes into the delivery station.
In den Ansprüchen 2 bis 6 sind vorteilhafte Ausgestaltungen der Erfindung offenbart. So ist es beispielsweise gemäß Anspruch 2 zweckmäßig, die Förderer für die Kuverts und die Kuvertinhalte kontinuierlich und die Gliederkette schrittweise umlaufen zu lassen. Dadurch erreicht man eine weitere Leistungssteigerung, weil die Zeiten für das Aufziehen des Kuverts auf das Spreizorgan bzw. das Einfüllen des Kuvertinhaltes und Abziehen des gefüllten Kuverts weiter reduziert werden können.Advantageous refinements of the invention are disclosed in claims 2 to 6. For example, it is expedient according to claim 2, the conveyors for the envelopes and the envelope contents continuously and to let the link chain circulate gradually. This results in a further increase in performance, because the times for opening the envelope on the expansion element or filling in the envelope contents and removing the filled envelope can be reduced further.
Gemäß Anspruch 3 empfiehlt es sich, die Förderer für die Kuverts und die Kuvertinhalte im Übergabebereich in horizontaler Ebene (in Etagen übereinander) und die Gliederkette in vertikaler Richtung umlaufen zu lassen.According to claim 3, it is advisable to have the conveyors for the envelopes and the envelope contents in the transfer area in a horizontal plane (one above the other in levels) and the link chain in the vertical direction.
Ein weiterer Gegenstand der Erfindung betrifft die besondere Ausbildung der Gliederkette gemäß Anspruch 4. Danach besteht die Gliederkette aus zwei im Abstand voneinander angeordneten und um zueinander paralleleAnother object of the invention relates to the special design of the link chain according to claim 4. Thereafter, the link chain consists of two spaced apart and parallel to each other
Achsen umlaufenden Einzelketten, an denen die Spreizorgane jeweils in gleicher Ebene gegeneinander gerichtet angeordnet sind. Das herangeführte Kuvert kann also mühelos beim Aufziehen auf die beiden zueinander parallel ausgerichteten Spreizorgane gespreizt werden, wodurch der Vorteil erzielt wird, daß eine größere Menge Kuvertinhalt eingeführt werden kann. Die mit dem Kuvert beladenen Spreizorgane werden schrittweise in eine angehobene Etage versetzt, welche Kollisionen mit den Greifwerkzeugen für die Kuverts verhindert. Es ist daher zweckmäßig, daß die Einzelkette mindestens vier, vorzugsweise acht, im gleichen Abstand voneinander angeordnete Spreizorgane aufweist.Single chains encircling axes, on which the spreading elements are each arranged in the same plane directed towards one another. The inserted envelope can thus be easily expanded when it is pulled onto the two mutually parallel spreading members, whereby the advantage is achieved that a larger amount of envelope content can be inserted. The spreading elements loaded with the envelope are gradually moved to a raised level, which prevents collisions with the gripping tools for the envelopes. It is therefore expedient for the single chain to have at least four, preferably eight, spreading members arranged at the same distance from one another.
Um die Taktzeiten zu verkürzen, ist gemäß Anspruch 6 der Erfindung vorgesehen, daß der Förderer für die Kuverts mehrere im gleichen Abstand zueinander angeordnete Greifer für das Erfassen der Kuvertklappen aufweist und in seinem unteren Trum die Kuverts von einer Stapelabzugseinrichtung übernimmt und in seinem oberen Trum die Kuverts an die Spreizorgane übergibt. Einzelheiten der Erfindung sind in der Zeichnung schematisch und beispielsweise dargestellt. Es zeigen:In order to shorten the cycle times, it is provided according to claim 6 of the invention that the conveyor for the envelopes has a plurality of grippers arranged at the same distance from one another for grasping the envelope flaps and takes over the envelopes from a stack pull-off device in its lower run and the one in its upper run Passes envelopes to the expansion organs. Details of the invention are shown schematically and for example in the drawing. Show it:

Kuvertinhalte in Kuverts.Envelope contents in envelopes.
Im Ausführungsbeispiel der Figur 1 wird davon ausgegangen, daß die Kuverts (20) von einem Stapel (1), einem Zwischenstapel oder von einer bestimmten Position mit Hilfe einer Abzugseinrichtung (2) abgezogen und einem Förderer (5) übergeben werden. Dieser Förderer (5) ist beispielsweise als umlaufender Zahnriemen ausgebildet und mit mehreren Greifern (17) versehen und läuft um horizontale Achsen um. Wesentlich ist, daß dieser Förderer (5) mit seinem oberen Trum (19) eine Förderebene (13) bildet, die sich horizontal erstreckt. Das untere Trum (18) dieses Förderers (5) erstreckt sich hingegen in der Abzugsebene der Abzugseinrichtung (2) . In deutlicher Höhendistanz zur Förderebene (13) des Förderers (5) für Kuverts (20) befindet sich die Förderebene (12) des Förderers (6) für Kuvertinhalte (21) . Diese Kuvertinhalte (21) befinden sich in einem oder mehreren Stapeln (3), denen Abzugseinrichtungen (4) zugeordnet sind. Dadurch ist es möglich, einen aus mehreren Blättern bestehenden Kuvertinhalt (21) auf dem Förderer (6) zu vereinigen, um diese mehreren Blätter in einem Pack in das Kuvert (20) zu führen. Es ist aber auch denkbar, mehrere Stapel (3) für gleiche Kuvertinhalte (21) hintereinander anzuordnen, um die abgezogenen Kuvertinhalte wechselweise auf den Förderer (6) aufzubringen. Dadurch kann man die Taktzeiten verringern, nämlich dann, wenn die Förderleistung des Förderers (6) für Kuvertinhalte größer als die Zuführleistung der einzelnen Abzugsvorrichtung (4) ist.In the exemplary embodiment in FIG. 1, it is assumed that the envelopes (20) are removed from a stack (1), an intermediate stack or from a specific position with the aid of a removal device (2) and transferred to a conveyor (5). This conveyor (5) is designed, for example, as a rotating toothed belt and is provided with a plurality of grippers (17) and rotates around horizontal axes. It is essential that this conveyor (5) with its upper run (19) forms a conveyor plane (13) which extends horizontally. The lower run (18) of this conveyor (5), on the other hand, extends in the take-off plane of the take-off device (2). The conveying plane (12) of the conveyor (6) for envelope contents (21) is located at a clear height from the conveying plane (13) of the conveyor (5) for envelopes (20). These envelope contents (21) are located in one or more stacks (3), to which deduction devices (4) are assigned. This makes it possible to combine an envelope content (21) consisting of several sheets on the conveyor (6) in order to feed these multiple sheets into the envelope (20) in one pack. However, it is also conceivable to arrange a plurality of stacks (3) for the same envelope contents (21) one behind the other in order to alternately apply the removed envelope contents to the conveyor (6). This makes it possible to reduce the cycle times, namely when the conveying capacity of the conveyor (6) for envelope contents is greater than the feeding capacity of the individual removal device (4).
Die Förderebene (12) des Förderers (6) für Kuvertinhalte (21) verläuft parallel zur Förderebene (13) des Förderers (5) für Kuverts (20) und weist von diesem eine deutliche Distanzierung auf. Dieser Zwischenraum zwischen beiden Förderebenen (12,13) wird ausgefüllt durch eine Spreizanordnung (7) für Kuverts (20), die ihrerseits aus einer Gliederkette (10) besteht, welche mehrere Spreizorgane (9) (Einpacktaschen) besitzt, wie dies im einzelnen in den Figuren 2 bis 4 dargestellt ist. Die Gliederkette (10) läuft in einer vertikalen Förderebene gemäß Pfeil 11 um und ist dazu bestimmt, die SpreizorganeThe conveyor plane (12) of the conveyor (6) for envelope contents (21) runs parallel to the conveyor plane (13) of the conveyor (5) for envelopes (20) and has a clear distance from it. This space between the two conveyor levels (12, 13) is filled by a spreading arrangement (7) for envelopes (20), which in turn consists of a link chain (10) which has several spreading elements (9) (packing pockets), as detailed in Figures 2 to 4 is shown. The link chain (10) rotates in a vertical conveying plane according to arrow 11 and is intended for the spreading elements
(9) in den Wirkungsbereich der Greifer (17) des Förderers (5) für Kuverts längs der Förderebene (13) zu bringen und alsdann in die Höhe der Förderebene (12) des Förderers (6) für Kuvertinhalte (21) anzuheben. Weil die Gliederkette(9) into the effective range of the grippers (17) of the conveyor (5) for envelopes along the conveying plane (13) and then raised to the height of the conveying plane (12) of the conveyor (6) for envelope contents (21). Because the link chain
(10) mehrere Spreizorgane (9) mit gleichem Abstand hintereinander aufweist, wird das in der Förderebene (13) befindliche Spreizorgan (9) mit dem geöffneten Kuvert beschickt, während ein anderes, in der Förderebene (12) befindliche Spreizorgan (9) das enthaltene gespreizte Kuvert (20) zum Einschieben des Kuvertinhaltes (21) und zum Abziehen des gefüllten Kuverts bereithält.(10) has a plurality of expansion elements (9) at the same distance one behind the other, the expansion element (9) located in the conveyor plane (13) is loaded with the open envelope, while another expansion element (9) located in the conveyor plane (12) contains it spread Envelope (20) ready to insert the contents of the envelope (21) and to pull off the filled envelope.
Demgemäß können die Taktzeiten der erfindungsgemäßen Kuvertiermaschine wesentlich reduziert werden, denn es empfiehlt sich, die Förderer (5 und 6) kontinuierlich umlaufen zu lassen, wohingegen die Gliederkette (10) mit den Spreizorganen (9) schrittweise angetrieben wird.Accordingly, the cycle times of the inserting machine according to the invention can be significantly reduced, because it is advisable to have the conveyors (5 and 6) circulate continuously, whereas the link chain (10) with the spreading elements (9) is driven step by step.
Im Beispiel der Figur 2 ist die Gliederkette (10) mit daran befestigten Spreizorganen (9) vergrößert dargestellt. Während das untere Spreizorgan (9) noch kein Kuvert aufgenommen hat, erkennt man an dem mittleren und oberen Spreizorgan (9), wie das Kuvert (20) mit seiner Kuvertklappe (23) voran auf die Spreizorgane (9) aufgeschoben worden ist.In the example in FIG. 2, the link chain (10) with spreading members (9) attached to it is shown enlarged. While the lower spreader (9) has not yet received an envelope, the middle and upper spreader (9) show how the envelope (20) with its envelope flap (23) has been pushed onto the spreader (9).
Besonders deutlich ist dieser Aufziehvorgang aus Figur 3 ersichtlich. Die jeweils in innerer Position befindlichen Spreizorgane (9) greifen in den Randbereich der geöffneten Kuverts (20) und halten dieses fest und bilden außerdem eine Ausspreizung des Kuverts (20) . In dieser Position werden die Kuverts (20) in die Höhe der Förderebene (12) für die Kuvertinhalte (21) gebracht.This mounting process can be seen particularly clearly from FIG. 3. The spreading members (9) located in the inner position reach into the edge region of the opened envelope (20) and hold it firmly and also form an expansion of the envelope (20). In this position, the envelopes (20) are brought to the level of the conveying plane (12) for the envelope contents (21).
Im Beispiel der Figur (4) ist ersichtlich, daß die Gliederkette (10) in zwei Einzelketten (14,15) unterteilt ist, die um parallele horizontale Achsen (16) in Distanz voneinander umlaufen und beispielsweise aus Zahnriemen bestehen können. Die Spreizorgane (9) der beiden Einzelketten (14,15) liegen, wenn sie sich in den Förderebenen (12) bzw. (13) befinden, parallel zueinander. Demgemäß wird ein geöffnetes Kuvert auf jeweils zwei einander gegenüberliegende Spreizorgane (9) aufgezogen. Das einzelne Spreizorgan (9) braucht daher lediglich in den ihm zugeordneten Kuvertrand einzudringen, wodurch sich eine maximale Spreizung ergibt, die es ermöglicht, auch eine größere Menge des Kuvertinhaltes (21) einzuführen.In the example of Figure (4) it can be seen that the link chain (10) is divided into two individual chains (14, 15), which run around each other around parallel horizontal axes (16) and can consist, for example, of toothed belts. The spreading elements (9) of the two individual chains (14, 15) are parallel to one another when they are in the conveying planes (12) or (13). Accordingly, an open envelope is pulled onto two mutually opposite spreading members (9). The individual expansion element (9) therefore only needs to penetrate into the envelope edge assigned to it, which results in a maximum expansion, which also makes it possible to insert a larger amount of the envelope content (21).
Die Figur 5 zeigt in vergrößerter Darstellung, wie das abgezogene und geöffnete Kuvert (20) vom Greifer (17) des Kuvertförderers (5) erfaßt und längs des unteren Trums (18) dieses Kuvertförderers (5) in Pfeilrichtung mitgenommen wird.FIG. 5 shows in an enlarged view how the removed and opened envelope (20) is gripped by the gripper (17) of the envelope conveyor (5) and taken along the lower run (18) of this envelope conveyor (5) in the direction of the arrow.
Die in Figur 6 vergrößert dargestellte Anordnung zum Einführen der Kuvertinhalte (21) in Kuverts (20) umfaßt einen mit Mitnehmern (24) versehenen Förderer (25), dessen Mitnehmer (24) die auf der Förderebene (12) befindlichen Kuvertinhalte (21) rückseitig erfassen und in die bereit gehaltenen Kuverts (20) einschieben. The arrangement, shown enlarged in FIG. 6, for inserting the envelope contents (21) into envelopes (20) comprises a conveyor (25) provided with drivers (24), whose drivers (24) have the envelope contents (21) on the conveying plane (12) on the back Detect and insert into the ready-made envelopes (20).
