Description

Die Erfindung betrifft eine Handhabungsstation zum Bewegen von blattartigem Fördergut auf einem geradlinigen, begrenzten Handhabungsweg, insbesondere eine Kuvertiereinrichtung zum Einschub von Einlagen in Kuverts.The invention relates to a handling station for moving sheet-like material to be conveyed on a straight, limited handling path, in particular an inserting device for inserting inserts into envelopes.

Handhabungsstationen dieser Art sind beispielsweise aus der DE-OS 41 16 708 bekannt. Sie enthalten eine oberhalb einer horizontalen Basisplatte gestellfest gelagerte Lenkerarmanordnung in Gestalt eines Antriebshebels, der von einer Antriebseinrichtung zur Erzeugung von Schwenkbewegungen des unteren Teils des Antriebshebels etwa in Richtung der Einschubbewegung verschwenkbar ist. Am unteren Teil des Antriebshebels sind schwenkbare, von Federmitteln nach abwärts vorgespannte Finger angeordnet, deren äußere Enden während eines Arbeitshubes auf der Basisplatte aufliegen und auf ihr vorwärts geschoben werden und während eines Rückhubes von der Basisplatte gemeinsam mittels einer Leitkulissenanordnung angehoben werden.Handling stations of this type are for example from DE-OS 41 16 708 known. They contain one above a horizontal base plate frame-mounted handlebar arm assembly in the form of a drive lever by a drive device for generating pivotal movements of the lower Part of the drive lever can be pivoted approximately in the direction of the insertion movement is. At the lower part of the drive lever are pivotable, by spring means downward biased fingers, the outer ends of which during a Work strokes rest on the base plate and are pushed forward on it and during a return stroke from the base plate together by means of a guide link arrangement be raised.

Damit nun die am unteren Antriebshebelende angelenkten, schwenkbaren Finger auch bei hohen Taktgeschwindigkeiten der Kuvertiereinrichtung zuverlässig auf der Basisplatte bzw. in darin vorgesehenen Rillen aufliegen und vermieden wird, daß die am hinteren Rand der Einlagen für die Kuverts anzusetzenden äußeren Enden der Finger nicht diesen hinteren Rand des Fördergutes verfehlen, ist man bestrebt, die Anlenkstelle der Finger der Kuvertiereinrichtung an der Lenkerarmanordnung, also bei der Einrichtung nach der DE-OS 41 16 708, am unteren Ende des Antriebshebels, möglichst gleichförmig etwa horizontal über die Basisplatte hinzubewegen, weshalb die Länge des Antriebshebels der bekannten Einrichtung von der gestellfesten Anlenkstelle oberhalb der Basisplatte bis zu der Anlenkstelle für die Finger möglichst groß gewählt wird, damit das untere Antriebshebelende bei den Schwenkbewegungen des Antriebshebels einen möglichst großen, die geradlinige Bewegung annähernden Kreisbogen beschreibt. Dies bedingt bei bekannten Einrichtungen dieser Art eine verhältnismäßig große Bauhöhe der gesamten Einrichtung.So that the pivotable at the lower end of the drive lever Fingers even at high cycle speeds of the inserting device lie reliably on the base plate or in the grooves provided therein and it is avoided that at the rear edge of the inserts for the envelopes the outer ends of the fingers do not have this rear edge of the If the material to be conveyed fails to be conveyed, the aim is to link the fingers of the Inserting device on the handlebar arm arrangement, that is to say when setting up DE-OS 41 16 708, at the lower end of the drive lever, if possible to move uniformly approximately horizontally over the base plate, which is why the Length of the drive lever of the known device from the fixed frame Articulation point above the base plate up to the articulation point for the fingers if possible is chosen large, so that the lower drive lever end with the Pivotal movements of the drive lever as large as possible, the straight line Describes movement approximate circular arc. This requires known ones Facilities of this type have a relatively large overall height Facility.

Man hat versucht, die Bauhöhe einer Handhabungsstation bzw. einer Kuvertiereinrichtung der vorstehend allgemein beschriebenen Art dadurch zu verringern, daß für die Bewegung der Schwenklagerung der Finger über die Basisplatte hin ein Linear-Antriebsmechanismus verwendet wurde. Konstruktionen dieser Art führen zwar in vorteilhafter Weise zu einer Verringerung der Gesamtbauhöhe der Einrichtung, verteuern aber eine Handhabungsstation bzw. eine Kuvertiereinrichtung insbesondere dann, wenn hohe Taktgeschwindigkeiten angestrebt werden, ganz wesentlich.Attempts have been made to determine the overall height of a handling station or one In this way, inserting device of the type generally described above reduce that for the movement of the pivot bearing of the fingers over the Base plate towards a linear drive mechanism was used. Constructions this type lead to a reduction in the advantageous Overall height of the facility, but make a handling station or an inserting device especially when high clock speeds be aimed for, very essential.

Durch die Erfindung soll die Aufgabe gelöst werden, eine Handhabungsstation bzw. eine Kuvertiereinrichtung der eingangs definierten allgemeinen Art so auszugestalten, daß eine Verringerung der Bauhöhe bei vergleichsweise einfachem und kostensparendem Aufbau erzielt wird und eine hohe Zuverlässigkeit der Bewegung der die zu handhabenden Gegenstände fördernden Finger erreicht wird.The object of the invention is to solve a problem Handling station or an inserting device of the initially defined general type so that a reduction in the overall height at comparatively simple and cost-saving structure is achieved and a high Reliability of the movement of the objects to be handled promoting finger is reached.

Diese Aufgabe wird erfindungsgemäß durch die in Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the in claim 1 specified features solved.

Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der dem Anspruch 1 nachgeordneten Patentansprüche, wobei allerdings hier angemerkt sei, daß den Gegenständen der Ansprüche 4 bis 6 unabhängig von den Merkmalen der vorausgehenden Ansprüche Bedeutung zukommt.Advantageous refinements and developments are the subject of the Claim 1 subordinate claims, although it should be noted here that the objects of claims 4 to 6 regardless of the features of previous claims are of importance.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert. Es stellen dar:

  • Fig. 2 eine schematische, perspektivische Abbildung einer Kuvertiereinrichtung mit den Grundzügen einer praktischen Konstruktion, und
  • Fig. 3 eine schematische, perspektische Ansicht eines Teiles der Kuvertiereinrichtung nach Fig. 2 gemäß einer Abwandlung.
    • A preferred exemplary embodiment is explained in more detail below with reference to the drawing. They represent:
  • 1 is a schematic side view of a handling station or an inserting device of the type specified here, shown in greatly simplified form, in side view,
  • Fig. 2 is a schematic, perspective illustration of an inserting device with the basic features of a practical construction, and
  • Fig. 3 is a schematic, perspective view of a part of the inserting device according to Fig. 2 according to a modification.

    • Fig. 1 zeigt in Seitenansicht eine Basisplatte 1, auf deren Oberseite Einschubfinger 2 in einer mit Bezug auf die Zeichenebene parallelen Richtung horizontal verschiebbar sind. Die Einschubfinger 2 sind über Fingeransätze 3 schwenkbar an einem nachfolgend als Lenkerhand 4 bezeichneten Teil einer Lenkeranordnung 5 angelenkt, wobei diese Lenkeranordnung außer der Lenkerhand 4 zwei mit ihr verbundene Lenkerarme 6 und 7 unterschiedlicher Länge enthält.Fig. 1 shows a side view of a base plate 1, on the top Insert finger 2 in a direction parallel to the plane of the drawing are horizontally displaceable. The insertion fingers 2 are over finger attachments 3 pivotable on a part referred to below as the handlebar hand 4 Handlebar arrangement 5 articulated, this handlebar arrangement except the Handlebar hand 4 two connected to it handlebar arms 6 and 7 different Contains length.

    Die jeweils oberen Enden der Lenker 6 und 7 sind, wie in Fig. 1 angedeutet, gestellfest oberhalb der Basisplatte 1 gelagert, während die unteren Enden der Lenkerarme 6 und 7 in bestimmtem Abstand voneinander gelenkig an die Lenkerhand 4 angeschlossen sind, so daß das freie, auskragende Ende der Lenkerhand 4 auf der Seite der Gelenkanschlußstelle des längeren Lenkerarmes 6 gelegen ist. An diesem freien Ende der Lenkerhand 4 sind die Fingeransätze 3 der Einschubfinger 2 gelenkig angeschlossen und durch Federmittel, welche in den Fig. 1 und 2 nicht gezeigt sind, innerhalb eines bestimmten Schwenkbereiches nach abwärts in Richtung auf die Oberfläche der Basisplatte 1 vorgespannt.The respective upper ends of the links 6 and 7 are, as indicated in FIG. 1, fixed to the frame above the base plate 1, while the lower ends of the Handlebar arms 6 and 7 articulated at a certain distance from each other to the handlebar hand 4 are connected so that the free, projecting end of the handlebar hand 4th is located on the side of the joint connection point of the longer handlebar arm 6. On this free end of the handlebar hand 4 are the finger attachments 3 of the insertion fingers 2 connected in an articulated manner and by spring means, which are not shown in FIGS. 1 and 2 are shown, within a certain swivel range downwards in Biased towards the surface of the base plate 1.

    Die gestellfesten Schwenklager für die Lenkerarme 6 und 7 sind in der Zeichnung mit 8 bzw. 9 bezeichnet.The frame-fixed swivel bearings for the handlebar arms 6 and 7 are in the Drawing 8 and 9 respectively.

    Werden mit Bezug auf die Darstellung von Fig. 1 und mit Bezug auf die gezeichnete Orientierung der Teile durch geeignete Fördermittel Einlagen parallel zur Oberfläche der Basisplatte 1 (in Blickrichtung des Betrachters auf die Zeichnungsebene hin) auf die Basisplatte 1 gefördert, so können diese Einlagen, von denen eine bei 10 angedeutet ist, durch eine Vorwärtsbewegung der Einschubfinger 2 mit Bezug auf die Darstellung von Fig. 1 von rechts nach links in ein in Fig. 1 bei 11 angedeutetes Kuvert eingeschoben werden, wozu die Einschubfinger 2 sich an dem rechts liegenden Rand der Einlage 10 andrücken und die Einlage 10 von links nach rechts in das Kuvert 11 hineinverschieben.1 and with reference to the drawn orientation of the parts in parallel by means of suitable funding to the surface of the base plate 1 (in the viewing direction of the viewer on the Level) on the base plate 1, these inserts, one of which is indicated at 10, by a forward movement of the Insert finger 2 with reference to the illustration of FIG. 1 from right to left in an envelope indicated in Fig. 1 at 11 are inserted, for which the Push in finger 2 on the right edge of insert 10 and insert the insert 10 into the envelope 11 from left to right.

    Zur Durchführung dieser Verschiebungsbewegung der Einschubfinger 2 über die Einschubfingeransätze 3 wird bei der Ausführungsform nach Fig. 1 der längere der Lenkerarme 6 im Uhrzeigersinn verschwenkt, wozu an den Lenkerarm 6 nahe seiner Gelenkstelle 8 ein Winkelschenkel 12 angesetzt ist, der über eine Kuppelstange 13 mit einem Kurbelantrieb 14 in Verbindung steht. Die Kurbel 14 wird synchron mit dem Arbeitstakt der Handhabungsstation bzw. der Kuvertiereinrichtung, und soweit diese Bestandteil einer Postbearbeitungsmaschine ist, synchron mit dem Arbeitstakt der gesamten Anlage angetrieben.To carry out this displacement movement of the insertion fingers 2 over the insertion finger attachments 3 is the longer one in the embodiment according to FIG. 1 the handlebars 6 pivoted clockwise, which is close to the handlebar 6 an articulated leg 12 is attached to its hinge point 8, which has a Coupling rod 13 is connected to a crank drive 14. The crank 14 is synchronized with the work cycle of the handling station or Inserting device, and insofar as this is part of a mail processing machine is driven synchronously with the work cycle of the entire system.

    Von wesentlicher Bedeutung für die Funktionsweise und die besonderen Eigenschaften der aus den beiden Lenkerarmen 6 und 7 und der Lenkerhand 4 aufgebauten Lenkeranordnung ist es, daß die Länge der Lenkerarme zwischen ihren gestellfesten Anlenkstellen 8 und 9 einerseits und ihren jeweiligen Anlenkstellen an der Lenkerhand 4 andererseits und auch der gegenseitige Abstand der Anlenkstellen der Lenkerarme an der Lenkerhand 4 so gewählt sind, daß die Schwenkbewegungen der Lenkerarme 6 und 7 unter der Wirkung der aus der Kurbel 14, der Kurbelstange 13 und dem Winkelschenkel 12 gebildeten Antriebsverbindung dazu führen, daß sich die Anlenkstelle der Einschubfinger 2 am auskragenden Ende der Lenkerhand 4 etwa parallel über die Oberfläche der Basisplatte 1 hin bewegt.Essential for functioning and special Properties of the two handlebar arms 6 and 7 and the handlebar hand 4 constructed handlebar assembly is that the length of the handlebar arms between their fixed articulation points 8 and 9 on the one hand and their respective Articulation points on the handlebar hand 4 on the other hand and also the mutual distance the articulation points of the handlebars on the handlebar hand 4 are selected so that the Pivotal movements of the handlebars 6 and 7 under the effect of the Crank 14, the crank rod 13 and the angle leg 12 formed Drive connection cause the articulation point of the insertion fingers 2 at the projecting end of the handlebar hand 4 approximately parallel over the surface of the Base plate 1 is moved.

    Darüberhinaus wird dafür Sorge getragen, daß während eines bestimmten Teiles des Arbeitshubes der Handhabungsstation bzw. der Kuvertiereinrichtung, nämlich nahe dem Übergang vom Arbeitshub in den Rückhub, die Lenkerhand 4 etwa parallel zu sich selbst horizontal über die Basisplatte hin bewegt wird. Beide Bewegungscharakteristiken der Lenkerhand 4, die aufgrund ihrer besonderen Kopplung zu den gestellfesten Lagerungsstellen 8 und 9 über die unterschiedlich langen Lenkerarme 6 und 7 erreicht werden, führen dazu, daß die Einschubfinger 2 über die Basisplatte bzw. über darin vorgesehene Rillen im wesentlichen ruhig und stabil bewegt werden.In addition, care is taken that during a certain Part of the working stroke of the handling station or the inserting device, namely, near the transition from the working stroke to the return stroke, the handlebar hand 4 is moved approximately parallel to itself horizontally over the base plate. Both Movement characteristics of the handlebar hand 4, due to their special Coupling to the frame-fixed storage locations 8 and 9 via the different long handlebar arms 6 and 7 are reached, cause the insertion fingers 2nd on the base plate or on the grooves provided therein, essentially calm and be moved stably.

    Die zumindest angenäherte Horizontalführung der Anlenkstellen der Einschubfinger 2 mittels einer lediglich Schwenklager aufweisenden Lenkeranordnung 5 führt zu einem einfachen, wenig störungsanfälligen und auch für hohe Arbeitsgeschwindigkeiten geeigneten Aufbau.The at least approximated horizontal guidance of the articulation points of the Insert finger 2 by means of a swivel bearing only Handlebar arrangement 5 leads to a simple and less prone to malfunction Construction suitable for high working speeds.

    Anstelle der zuvor erwähnten Zuförderung von Einlagen 10 auf die Basisplatte 11 in Blickrichtung des Betrachters von Fig. 1 oder zusätzlich zu einer solchen Einlagenzuförderung kann die Zuförderung von Einlagen 10' mittels einer taktweise oder kontinuierlich angetriebenen Fördereinrichtung in Gestalt eines Förderbandes oder einer Förderkette 15 vorgenommen werden, dessen bzw. deren Förderrichtung auf dem Obertrum mit der Richtung des Arbeitshubes der Handhabungsstation bzw. der Kuvertiereinrichtung übereinstimmt. Förderfinger 16 der Förderkette oder des Förderbandes schieben auf dem Obertrum die Einlagen 10' vor sich her, wobei der Bewegungsweg der Förderfinger 16 mit Bezug auf die Lage quer zur Förderrichtung neben dem Bewegungsweg der Einschubfinger 2 parallel zu diesem Bewegungsweg verläuft, derart, daß die Einschubfinger 2 beim Arbeitshub und bei dem Rückhub an dem taktweise oder kontinuierlich vorwärts wandernden Förderfingern 16 vorbeigeführt werden können.Instead of the aforementioned contribution of deposits 10 on the Base plate 11 in the viewing direction of the viewer of FIG. 1 or in addition to one such deposit support can be the supply of deposits 10 'by means of a cyclically or continuously driven conveyor in the form of a Conveyor belt or a conveyor chain 15 are made, his or her Direction of conveyance on the upper run with the direction of the working stroke of the handling station or the inserting device matches. Conveyor finger 16 of the Conveyor chain or conveyor belt push the inserts 10 'on the upper run ahead of itself, the path of movement of the conveyor fingers 16 with respect to the Position transverse to the conveying direction next to the path of movement of the insertion fingers 2 runs parallel to this path of movement, such that the insertion fingers 2 at Working stroke and on the return stroke on the cyclical or continuous forward wandering funding fingers 16 can be passed.

    Haben die Einschubfinger 2 eine Einlage 10 in ein Kuvert 11 eingeschoben, so können sie in der Rückhubbewegung rasch hinter eine Augenblicksstellung eines der Förderfinger 16 gebracht werden und führen dann aufgrund einer entsprechenden Abstimmung der Antriebsgeschwindigkeiten der Kurbel 14 einerseits und eines Antriebs 17 für das Förderband oder die Förderkette 15 andererseits eine raschere Bewegung im Arbeitshub aus, als der Vorschub der Förderfinger 16 beträgt. Eine Einlage 10' wird daher nun durch die Einschubfinger 2 von dem zugehörigen Förderfinger 16 abgehoben, über die Basisplatte 1 geschoben und in das Kuvert 11 eingebracht. Zwischenzeitlich wandert der zurückgebliebene Förderfinger 16 über entsprechende Ausschnitte einer Deckplatte des Förderbandes oder der Förderkette und einen Ausschnitt der Basisplatte 1 auf das Untertrum des Förderbandes bzw. der Förderkette.If the insertion fingers 2 have inserted an insert 10 into an envelope 11, so they can quickly move past an instantaneous position in the return stroke one of the conveyor fingers 16 are brought and then perform due to a corresponding Coordination of the drive speeds of the crank 14 on the one hand and a drive 17 for the conveyor belt or chain 15 on the other hand faster movement in the working stroke than the feed of the feed fingers 16 is. An insert 10 'is now by the insertion fingers 2 of the associated conveyor finger 16 lifted, pushed over the base plate 1 and in inserted the envelope 11. In the meantime, the one left behind is wandering Conveyor fingers 16 over corresponding cutouts in a cover plate of the conveyor belt or the conveyor chain and a section of the base plate 1 on the lower strand of the Conveyor belt or the conveyor chain.

    Einzelheiten der anhand von Fig. 1 bisher beschriebenen Handhabungsstation bzw. Kuvertiereinrichtung sind aus Fig. 2 zu erkennen, wobei in Fig. 2 für entsprechende Teile jeweils gleich Bezugszeichen wie in Fig. 1 verwendet sind. Details of those previously described with reference to FIG. 1 Handling station or inserting device can be seen from Fig. 2, wherein in FIG. 2 for corresponding parts in each case the same reference numerals as in FIG. 1 are used.

    Um einen möglichst großen Schwenkbereich der Lenkerarme 6 und 7 zuzulassen, müssen die jeweiligen Anlenkstellen an den bewegten Teilen und die Verbindung der gestellfesten Lagerung mit dem Gestell so ausgebildet sein, daß die Lenkerarme zumindest teilweise aneinander vorbeigeführt werden können.Around the largest possible swivel range of the handlebar arms 6 and 7 the respective articulation points on the moving parts and the Connection of the frame-fixed storage with the frame so that the handlebars can be at least partially guided past each other.

    Mit der Basisplatte 1 oder einem daran befestigten Gestellteil sind zwei Lagerwangen 18 und 19 fest verbunden, welche an ihren Enden mit Lageraugen 20 bzw. 21 versehen sind. In den Lageraugen 20 und 21 ist eine horizontal über der Basisplatte 1 verlaufende Achse 22 gelagert, auf welcher ein Winkelhebel 23, wie bei 24 angedeutet, verdrehungssicher befestigt ist. Der Winkelhebel 23 ist also in einer Radialebene zur Achse 22 präzise geführt.With the base plate 1 or a frame part attached to it are two Bearing cheeks 18 and 19 firmly connected, which at their ends with bearing eyes 20th or 21 are provided. In the bearing eyes 20 and 21 is a horizontally above Base plate 1 extending axis 22 mounted on which an angle lever 23, such as indicated at 24, is secured against rotation. The angle lever 23 is therefore in guided in a radial plane to the axis 22 precisely.

    Ein in der Stellung von Fig. 2 vertikal nach abwärts weisender Hebelschenkel bildet den vorerwähnten längeren Lenkerarm 6 und ein zu diesem im wesentlichen senkrecht orientierter Hebelschenkel bildet den vorerwähnten Winkelschenkel 12. Die Darstellung von Fig. 2 läßt auch die anhand von Fig. 1 beschriebenen Teile des Antriebsmechanismus, nämlich die Kuppelstange 13 und den Kurbelantrieb 14 erkennen.A vertically downward in the position of Fig. 2 Lever arm forms the aforementioned longer handlebar arm 6 and one to this essentially vertically oriented lever arm forms the aforementioned Angle leg 12. The illustration in FIG. 2 also allows the illustration in FIG. 1 described parts of the drive mechanism, namely the coupling rod 13 and recognize the crank drive 14.

    Das untere Ende des Lenkerarmes 6 ist in der aus Fig. 2 ersichtlichen Weise gegabelt und an der Lenkerhand 4 zwischen deren Enden angelenkt. Ein abgeköpfter Teil 25 der Lenkerhand 4 dient zum gelenkigen Anschluß des Lenkerarmes 7 mit der geringeren Länge gegenüber der Längenabmessung des Winkelhebels 6.The lower end of the handlebar arm 6 is in the manner shown in FIG. 2 forked and articulated on the handlebar hand 4 between the ends. On skimmed part 25 of the handlebar hand 4 is used for the articulated connection of the Handlebar arm 7 with the shorter length compared to the length dimension of the Angle lever 6.

    Das obere Ende des Lenkerarmes 7 ist über das vorerwähnte Gelenk 9 an einem Bauwinkel 27 angeschlossen, der an der Lagerwange 28 befestigt ist. Aufgrund des relativ zur Schwenkrichtung der Lenkerarme 6 und 7 seitlichen Versatzes der Gelenkstelle 9 und auch der Anlenkung des Hebels 7 an der Abkröpfung 25 der Lenkerhand 4 können die Lenkerarme 6 und 7 zur Verwirklichung eines großen Schwenkbereiches aneinander vorbeigeführt werden.The upper end of the handlebar arm 7 is at the above-mentioned joint 9 connected to a construction angle 27, which is attached to the bearing cheek 28. Due to the lateral relative to the pivoting direction of the arm 6 and 7 Offset of the joint 9 and also the articulation of the lever 7 on the Bend 25 of the handlebar hand 4, the handlebar arms 6 and 7 for Realization of a large swivel range can be guided past each other.

    Fig. 3 zeigt, daß die Basisplatte 1 mit Führungsrillen 30 versehen sein kann, welche in Richtung des Arbeitshubes der Handhabungsstation bzw. der Kuvertiereinrichtung über die Oberfläche der Basisplatte 1 hin verlaufen. Während des Arbeitshubes verschieben sich die Einschubfinger 2 in diesen Rillen 30 und werden an ihren Fingeransätzen 3 dadurch in den Rillen 30 gehalten, daß eine gemeinsame Schwenkwelle 31, mit denen die Einschubfinger 2 über ihre Fingeransätze 3 gekuppelt sind, innerhalb eines bestimmten Schwenkbereiches S gegenüber der die Schwenkwelle 31 haltenden Lenkerhand 4 im Gegenuhrzeigersinn vorgespannt ist. Dies kann durch eine in Fig. 3 etwa bei 32 angedeutete, die Schwenkwelle 31 umschlingende Schraubenfeder 32 geschehen, welche einerseits an einem fest auf der Schwenkwelle 31 sitzenden Stellring und andererseits an einer Verankerungsstelle der Lenkerhand 4 verankert ist. Diesbezügliche Einzelheiten lassen sich jedoch in der dem Fachmann geläufigen Art und Weise abwandeln.3 shows that the base plate 1 can be provided with guide grooves 30, which in the direction of the working stroke of the handling station or The inserting device runs over the surface of the base plate 1. While of the working stroke, the insertion fingers 2 move in these grooves 30 and are held on their finger tips 3 in the grooves 30 that a common pivot shaft 31, with which the insertion fingers 2 over their Finger approaches 3 are coupled, within a certain swivel range S. opposite the handlebar hand 4 holding the pivot shaft 31 in Is biased counterclockwise. This can be done at 32 in FIG indicated coil spring 32 wrapping around the swivel shaft 31, which on the one hand on a fixed ring on the swivel shaft 31 and on the other hand is anchored at an anchoring point of the handlebar hand 4. Details in this regard can, however, be familiar to those skilled in the art Modify way.

    Die einzelnen Einschubfinger 2 und ihre Fingeransätze 3 sind jedoch nicht absolut drehfest mit der Schwenkwelle 31 gekuppelt. Vielmehr erfolgt die Kopplung über ein geringes Drehspiel s unter Federbelastung durch Vorspannmittel in Gestalt von die Schwenkwelle 31 umschlingenden Schraubenfedem 33, die einerseits an fest auf der Schwenkwelle 31 sitzenden Stellringen und andererseits an Verankerungsstellen der Fingeransätze 3 verankert sind.However, the individual insertion fingers 2 and their finger attachments 3 are not absolutely rotatably coupled with the swivel shaft 31. Rather, the Coupling via a small rotation s under spring load Preloading means in the form of helical springs wrapping around the pivot shaft 31 33, on the one hand on collars fixed on the swivel shaft 31 and on the other hand, are anchored at anchor points of the finger attachments 3.

    Am dem Betrachter zugekehrten Ende der Schwenkwelle 31 oder an einem der Einschubfingeransätze 3 ist versetzt eine Tastrolle 34 angeordnet, welche mit einer anhebbaren und absenkbaren Leitkulisse 35 derart zusammenwirkt, daß während des Arbeitshubes die Einschubfinger 2 sich abgesenkt in den Rillen 30 der Basisplatte 1 bewegen, während bei dem Rückhub die Tastrolle 34 in Zusammenwirkung mit der Leitkulisse 35 bewirkt, daß die Schwenkwelle 31 sich mit Bezug auf die Darstellung von Fig. 3 im Uhrzeigersinn verschwenkt und die Einschubfinger 3 mit ihren Ansätzen 3 im Uhrzeigersinn hochschwenkt. Auch diesbezügliche Einzelheiten sind dem Fachmann an sich bekannt.At the end of the pivot shaft 31 facing the viewer or at one the insertion finger lugs 3 is offset a feeler roller 34, which with a liftable and lowerable guide gate 35 cooperates such that during of the working stroke the insertion fingers 2 are lowered into the grooves 30 of the Move base plate 1, while on the return stroke the feeler roller 34 in Interaction with the guide link 35 causes the pivot shaft 31 3 pivoted clockwise with respect to the representation of FIG. 3 and the Insert finger 3 with its lugs 3 swings clockwise. Also details in this regard are known per se to the person skilled in the art.

    Bei der Ausführungsform nach Fig. 3 ist die Basisplatte 1 durch einen quer zum Arbeitshub der Handhabungsstation bzw. der Kuvertiereinrichtung verlaufenden Schlitz 36 unterteilt, der zum Durchtritt von Förderfingern 37 einer unter der Basisplatte 1 hindurchlaufenden Förderkette 38 dient.In the embodiment according to FIG. 3, the base plate 1 is transverse to the working stroke of the handling station or the inserting device running slot 36 divided, one for the passage of conveyor fingers 37 conveyor chain 38 running under the base plate 1 is used.

    Sollen bestimmte Einlagen oder zu handhabende Gegenstände während eines Arbeitshubs der in Fig. 3 gezeigten Einrichtung nicht von den Einschubfingern 2 erfaßt werden, so wird durch entsprechende Betätigung der Leitkulisse 35 dafür Sorge getragen, daß die Einschubfinger 2 auch während des Arbeitshubes und nicht nur während des Rückhubes von der Basisplatte 1 abgehoben bleiben. Es wird dann die Förderkette 8 in Betrieb gesetzt und die Förderfinger 37, welche über das Niveau der Oberfläche der Basisplatte 1 durch den Schlitz 36 aufragen, fördern solche liegengebliebenen Einlagen in Förderrichtung der Transportkette 28 weiter, um sie anderen Bearbeitungsstationen, etwa anderen Kuvertiereinrichtungen zuzuführen, wie dies beispielsweise aus der DE-OS 195 00 746 bekannt ist.Are certain deposits or objects to be handled during a Working strokes of the device shown in FIG. 3 are not from the insertion fingers 2 are detected, so by appropriate actuation of the guide link 35 Care is taken that the insertion fingers 2 during the working stroke and not only remain lifted off the base plate 1 during the return stroke. It the conveyor chain 8 is then put into operation and the conveyor fingers 37, which protrude above the level of the surface of the base plate 1 through the slot 36, promote such remaining deposits in the conveying direction of the transport chain 28 to other processing stations, such as other inserting devices to supply, as for example from DE-OS 195 00 746 is known.

    Es zeigt sich nun bei Handhabungsstationen bzw. Kuvertiereinrichtungen der vorliegenden angegebenen Art, daß die Einschubfinger 2 zuverlässige Laufeigenschaften auf der Basisplatte 1 auch dann aufweisen, wenn die Basisplatte durch Querschlitze nach der Art des Schlitzes 36 unterbrochen ist. In keiner Betriebsphase hat die untere, in der Rille 3 verlaufende Nase der Einschubfinger 2 das Bestreben, sich während des Arbeitshubes von der Basisplatte 1 abzuheben und den hinteren Rand des zu fördernden Gegenstandes bzw. der zu fördernden Anlage zu verlieren.It can now be seen in handling stations or inserting devices present specified type that the insertion fingers 2 reliable Have running properties on the base plate 1 even when the base plate is interrupted by transverse slots in the manner of slot 36. In no one The lower nose of the insertion finger 2 running in the groove 3 has the operating phase the effort to stand out from the base plate 1 during the working stroke and the rear edge of the object or objects to be conveyed Losing attachment.
