Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Binden von aufeinander gestapelten Flachteilen, insbesondere Papierbögen, mit Hilfe eines länglichen Verbindungsmittels, das im Querschnitt zwei gekrümmte Seitenabschnitte aufweist, die vor Einbringen in in Randabschnitten der Flachteile ausgebildete Perforationen geöffnet und nach Einbringen geschlossen sind, insbesondere eines Drahtkammes, wobei mit Hilfe einer Einbringeinrichtung das offene Verbindungsmittel in die Perforationen eingebracht und mit Hilfe einer Schließeinrichtung das in die Perforationen eingebrachte Verbindungsmittel geschlossen wird.The invention relates to a device and a method for binding stacked flat parts, in particular paper sheets, by means of an elongate connecting means having in cross section two curved side portions which are opened prior to introduction in formed in edge portions of the flat parts perforations and closed after insertion, in particular a wire comb, wherein introduced by means of a loading device, the open connection means in the perforations and with the aid of a closing device, the introduced into the perforations connecting means is closed.

Ferner zeigt die DE-A-3141686 eine Bindevorrichtung bei der des Drahtkamm durch Einbiegen seiner Seitenabschnitte gleizeitig in die Perforationen eingebracht und geschlossen wird.Furthermore, the shows DE-A-3141686 a binding device in which the wire comb is introduced and closed by bending its side sections in the perforations.

Eine Vorrichtung der eingangs genannten Art ist gewöhnlich Teil einer halbautomatisch oder vollautomatisch arbeitenden Anlage zur Herstellung von Papierblöcken, die mittels Drahtkämmen zusammengehalten werden. In derartigen Anlagen werden aus einer Papierbahn Papierbögen durch Schneiden hergestellt, wobei während dieses Arbeitsschrittes die Papierbögen gleichzeitig in einem Randabschnitt mit Hilfe einer Stanzvorrichtung perforiert und ggf. in einem Druckwerk bedruckt werden. Anschließend werden diese Papierbögen überlappt und zu Blöcken mit einer definierten Anzahl, von Papierbögen gesammelt. Dabei werden die Papierbögen so gestapelt, dass die perforierten Randabschnitte zueinander ausgerichtet sind. Letzteres ist wichtig, um in der Bindevorrichtung zum Binden der Papierblöcke die zu diesem Zeitpunkt noch offenen Drahtkämme mit ihren einen Schenkeln durch die Perforationen sämtlicher Papierbögen einführen und hindurchstecken zu können. Anschließend werden die noch offenen Drahtkämme geschlossen, indem die voneinander beabstandeten Schenkel jeweils aufeinanderzu gebogen werden, um auf diese Weise geschlossene ringförmige Segmente zu bilden.A device of the type mentioned is usually part of a semi-automatic or fully automatic plant for the production of paper blocks, which are held together by wire combs. In Such systems are produced from a sheet of paper sheets by cutting, wherein during this step, the paper sheets are perforated simultaneously in an edge portion using a punching device and possibly printed in a printing unit. Subsequently, these sheets of paper are overlapped and collected into blocks of a defined number, of paper sheets. The paper sheets are stacked so that the perforated edge portions are aligned with each other. The latter is important in order to be able to insert and then push through the perforations of all the paper sheets in the binding device for binding the paper blocks, the still open wire combs with their one legs. Thereafter, the still open wire combs are closed by bending the spaced-apart legs toward each other to form closed annular segments in this manner.

Die Drahtkämme bestehen aus einer Vielzahl von nebeneinander liegenden Schenkel- oder Segmentpaaren, die durch Verbindungssektionen miteinander verbunden sind, und haben deshalb die Form einer quer zu ihrer Längserstreckung beweglichen "Raupe". Die Drahtkämme werden so vorgefertigt, dass sie mit geöffneten Segmenten angeliefert werden. Im geöffneten Zustand sind demnach die Segmente jedes Segmentpaares mit ihren freien Enden voneinander beabstandet, wodurch jedes Segmentpaar und somit auch die Drahtkämme im Querschnitt die Form eines Doppel-"C" haben. Wegen dieser besonderen Form ist es wichtig, dass die Drahtkämme in der Bindevorrichtung möglichst präzise durch die .Perforationen der Papierbögen gesteckt werden, um ein reibungsloses Binden zu ermöglichen.The wire combs consist of a plurality of juxtaposed leg or segment pairs, which are interconnected by connecting sections, and therefore have the form of a "caterpillar" movable transversely to its longitudinal extent. The wire combs are prefabricated so that they are delivered with open segments. In the open state, therefore, the segments of each pair of segments are spaced apart with their free ends, whereby each pair of segments and thus also the wire combs have the shape of a double "C" in cross-section. Because of this particular shape, it is important that the wire combs in the binder be inserted as precisely as possible through the paper sheet perforations to allow for smooth binding.

Mit Hilfe der Erfindung lassen sich längliche Verbindungsmittel, die jeweils im Querschnitt zwei gekrümmte Seitenabschnitte aufweisen, die vor Einbringen in die Perforationen der Flachteile geöffnet sind, besonders präzise in die Perforationen einbringen und durch diese hindurch stecken. Dadurch wird ein reibungslosen Binden der Flachteile gewährleistet.With the help of the invention can be elongated connecting means, each having in cross-section two curved side portions, prior to introduction are opened in the perforations of the flat parts, very precisely bring in the perforations and stuck through them. This ensures a smooth binding of the flat parts.

Vorzugsweise fällt während der Schwenkbewegung die Schwenkachse des Schwenkmittels im Wesentlichen mit dem Drehpunkt der kreis- bzw. teilkreisförmigen Krümmung des Seitenabschnittes des Verbindungsmittels zusammen.Preferably, during the pivoting movement, the pivot axis of the pivoting means substantially coincides with the pivot point of the circular or part-circular curvature of the side portion of the connecting means.

Zweckmäßigerweise sollte die Einbringeinrichtung ein Eingriffsmittel zur Aufnahme des Verbindungsmittels aufweisen. Eine Weiterbildung dieser Ausführung, welche eine Aufnahmestation und eine Transporteinrichtung zum Transport des Verbindungsmittels zur Aufnahmestation aufweist, zeichnet sich dadurch aus, dass die Transporteinrichtung das Verbindungsmittel in Längsrichtung in die Aufnahmestation befördert, wo das Eingriffsmittel das Verbindungsmittel greift und entfernt.Appropriately, the introduction device should have an engagement means for receiving the connection means. A development of this embodiment, which has a receiving station and a transport device for transporting the connecting means to the receiving station, characterized in that the transport device conveys the connecting means in the longitudinal direction in the receiving station, where the engagement means engages and removes the connecting means.

Zum allgemeinen Verständnis ist in Fig. 1 schematisch eine Anlage zur Herstellung von mittels Drahtkämmen zusammengehaltenen Blöcken aus Papierbogen in einer beispielhaften Ausführung dargestellt.For the sake of general understanding, FIG. 1 schematically shows a plant for the production of blocks of paper sheets held together by wire combs in an exemplary embodiment.

Die Anlage gemäß Fig. 1 weist einen ersten, geradlinig verlaufenden Förderund Bearbeitungsabschnitt 1 und einen zweiten, gekrümmt verlaufenden Förder- und Bearbeitungsabschnitt 2 auf. Der Förderabschnitt 1 besteht aus einer Aufgabestation 3 mit einem Anschlag 4, an den Stapel 6 aus Papierbogen 7 mehrfacher Nutzenbreite von Hand angelegt werden. Zum Abfördern der Stapel 6 ist ein taktweise antreibbarer Förderer 8 mit Mitnehmern 9 vorgesehen, von dem aufeinanderfolgend die Stapel 6 zu einer Teilvorrichtung 11 förderbar sind. In der Teilvorrichtung 11 werden die Stapel 6 mit Hilfe einer Zange 12 in Teilstapel unterteilt, die zwischen zwei Förderbändern 13 und 14 zu einer Stanzvorrichtung 16 gefördert werden. Die Stanzvorrichtung 16 ist quer zur Förderrichtung der Stapel 6 angeordnet und wirkt derart mit einem steuerbaren Anschlag 17 zwischen nachfolgenden Förderbändern 18 und 19 zusammen, dass die Teilstapel im Bereich ihrer rückwärtigen Kante 21 mit einer Lochreihe 22 versehen werden. Von den Förderbändern 18 und 19 werden die mit einer Lochreihe 22 versehenen Teilstapel zu einer Sammelvorrichtung 23 gefördert, in der die Teilstapel wieder zu einem Stapel 6 angesammelt werden. Zum Abfördern aus der Sammelvorrichtung 23 dient eine steuerbare Zange 24, die die Stapel 6 soweit aus der Sammelvorrichtung 23 herauszieht, dass sie anschließend von einem taktweise angetriebenen Förderer bzw. von dessen Mitnehmern 26 erfaßt werden. Es folgt eine Schneidevorrichtung 27 mit in Förderrichtung angeordneten Messern 28, die die Stapel 6 mehrfacher Nutzenbreite in Blöcke 29 unterteilen. Die Blöcke 29 werden anschließend zur Weiterverarbeitung in nachfolgende Arbeitsstationen transportiert, für die in Fig. 1b lediglich pauschal das Bezugszeichen 30 angegeben ist.The plant according to FIG. 1 has a first, rectilinear conveying and processing section 1 and a second, curved conveying and processing section 2. The conveying section 1 consists of a feeding station 3 with a stop 4, are applied to the stack 6 of paper sheet 7 multiple use width by hand. For conveying the stack 6, a cyclically drivable conveyor 8 is provided with carriers 9, of which the stack 6 are successively conveyed to a dividing device 11. In the dividing device 11, the stack 6 are divided by means of a pair of pliers 12 into sub-stacks, between two Conveyor belts 13 and 14 are conveyed to a punching device 16. The punching device 16 is arranged transversely to the conveying direction of the stack 6 and cooperates with a controllable stop 17 between subsequent conveyor belts 18 and 19 such that the partial stacks are provided in the region of their rear edge 21 with a row of holes 22. Of the conveyor belts 18 and 19, the partial stacks provided with a row of holes 22 are conveyed to a collecting device 23, in which the partial stacks are again accumulated to form a stack 6. For discharging from the collecting device 23 is a controllable pliers 24 which pulls the stack 6 so far from the collecting device 23, that they are then detected by a cyclically driven conveyor or by its drivers 26. This is followed by a cutting device 27 with knives 28 arranged in the conveying direction, which divide the stacks 6 of multiple useful width into blocks 29. The blocks 29 are subsequently transported to subsequent workstations for further processing, for which only the reference number 30 is given in FIG. 1b.

Die nachfolgenden Arbeitsstationen können insbesondere eine Ausrichtvorrichtung, eine Drahtkamm-Einziehvorrichtung und eine Drahtkamm-Schließvorrichtung enthalten. Während die Ausrichtvorrichtung in den beiliegenden Zeichnungen nicht näher dargestellt ist, ist die mit dem Bezugzeichen 36 gekennzeichnete Drahtkamm-Einziehvorrichtung in den Figuren 2 bis 6 und die mit dem Bezugszeichen 38 gekennzeichnete Drahtkamm-Schließvorrichtung in den Figuren 2 und 7 erkennbar gezeigt.In particular, the subsequent workstations may include an alignment device, a wire comb retractor, and a wire comb closure device. While the alignment device is not shown in greater detail in the accompanying drawings, the wire comb retractor indicated by reference numeral 36 in Figs. 2 to 6 and the wire comb fastener indicated by reference numeral 38 are shown in Figs.

Wie die Figuren 2 bis 6 erkennen lassen, ist eine Transportvorrichtung 40 vorgesehen, die die bereits auf die benötigte Länge geschnittene, jedoch noch offenen Drahtkämme in die Drahtkamm-Einziehvorrichtung 36 transportiert. Hierzu ist im vorliegenden Ausführungsbeispiel die Transportvorrichtung 40 mit zwei zueinander rechtwinklig angeordneten Bandförderern versehen, auf deren Förderbänder der noch offene Drahtkamm aufliegt. In den Figuren 4 bis 7 verläuft die Transportrichtung und somit die sogenannte Drahtkammeinzugsebene rechtwinklig zur Bildebene. Deshalb ist in den Figuren 2 bis 6 der Drahtkamm, der mit dem Bezugszeichen 42 gekennzeichnet ist, in Stirnansicht dargestellt und erstreckt sich somit in seiner Längsausdehnung rechtwinklig zur Bildebene.As can be seen from FIGS. 2 to 6, a transport device 40 is provided which transports the wire combs, which have already been cut to the required length but are still open, into the wire comb retracting device 36. For this purpose, in the present embodiment, the transport device 40 is provided with two mutually perpendicular belt conveyors, on the conveyor belts of the still open wire comb rests. In FIGS. 4 to 7, the transport direction, and thus the so-called wire-comb feed-in plane, runs at right angles to the image plane. Therefore, in Figures 2 to 6 of Wire comb, which is designated by the reference numeral 42, shown in front view and thus extends in its longitudinal extent at right angles to the image plane.

In Fig. 3 ist die Situation gezeigt, in der der noch offene Drahtkamm 42 mit Hilfe der Transportvorrichtung 40 gerade in die Drahtkamm-Einziehvorrichtung 36 transportiert worden ist. Gut zu erkennen ist die geöffnete Doppel-C-Form des Drahtkammes 42 mit einem ersten etwa halbrunden Kammsegment 42a und einem zweiten etwa halbrunden Kammsegment 42b, deren freie Enden voneinander beabstandet sind.In Fig. 3, the situation is shown in which the still open wire comb 42 has been transported by means of the transport device 40 straight into the wire comb-Einziehvorrichtung 36. Good to see the open double C-shape of the wire comb 42 with a first approximately half-round comb segment 42a and a second approximately semi-circular comb segment 42b, the free ends of which are spaced apart.

In der in Fig. 3 gezeigten Betriebsstellung befindet sich der Drahtkamm 42 bereits in Klemmeingriff mit einer Klemmbackeneinheit 44, die eine unbewegliche untere erste Klemmbacke 46 und.eine bewegbare obere zweite Klemmbacke 48 aufweist. Dabei liegt der Drahtkamm 42 auf der ersten Klemmbacke 46 auf, während sich die zweite Klemmbacke 48 in Eingriff mit dem freien Ende des zweiten Schenkels 42b des noch offenen Drahtkammes 42 befindet. Angetrieben wird die bewegliche zweite Klemmbacke 48 von einer Pneumatikeinheit 49, die durch eine nicht dargestellte Steuereinheit entsprechend angesteuert wird, wodurch die Klemmbackeneinheit 44 wahlweise geschlossen oder geöffnet wird.In the operating position shown in FIG. 3, the wire comb 42 is already in clamping engagement with a jaw unit 44 having a stationary lower first jaw 46 and a movable upper second jaw 48. In this case, the wire comb 42 rests on the first jaw 46, while the second jaw 48 is in engagement with the free end of the second leg 42b of the still open wire comb 42. The movable second clamping jaw 48 is driven by a pneumatic unit 49, which is correspondingly driven by a control unit, not shown, whereby the clamping jaw unit 44 is selectively closed or opened.

Die Klemmbackeneinheit 44 und die Pneumatikeinheit 49 sind Teil einer Klemmeinheit 50, die einen Körper 51 aufweist, an dem ein Schieber 52 bewegbar gelagert ist. Der Schieber 52 weist ein außenliegendes Stirnelement 52a und parallel zueinander angeordnete Stangen 52b auf, die durch entsprechende (in den Figuren nicht näher bezeichnete) Bohrungen im Körper 51 geführt sind und an ihren gegenüberliegenden Enden die Klemmbackeneinheit 44 mit der zugehörigen Pneumatikeinheit 49 tragen. Durch Bewegung des Schiebers 52 gegenüber dem Körper 51 der Klemmeinheit 50 lässt sich die Lage der Klemmbackeneinheit 44 gegenüber dem Körper 51 der Klemmeinheit 50 entsprechend verändern.The jaw unit 44 and the pneumatic unit 49 are part of a clamping unit 50 having a body 51 on which a slider 52 is movably mounted. The slider 52 has an outer end member 52a and mutually parallel rods 52b, which are guided by corresponding (not shown in the figures unspecified) bores in the body 51 and carry at its opposite ends the jaw unit 44 with the associated pneumatic unit 49. By moving the slider 52 relative to the body 51 of the clamping unit 50, the position of the jaw unit 44 relative to the body 51 of the clamping unit 50 can be changed accordingly.

Am Stirnelement 52a des Schiebers 52 ist über ein Scharnier 53 das eine Ende 54a eines ersten Doppelhebels 54 angelenkt, welcher auf einer ersten Welle 56 drehbar gelagert ist. Drehfest auf der ersten Welle 56 sind dagegen mit ihrem einen Ende zwei voneinander beabstandete Tragarme 58 befestigt, die an ihren anderen freien Enden jeweils eine zweite Welle 60 tragen, an denen der Körper 51 der Klemmeinheit 50 mit seitlichen Tragarmen 51a verschwenkbar gelagert ist, wie neben Fig. 3 insbesondere auch Fig. 2 erkennen lässt.On the end element 52a of the slider 52, the one end 54a of a first double lever 54 is articulated via a hinge 53, which is rotatably mounted on a first shaft 56. Non-rotatably mounted on the first shaft 56, however, are at one end two spaced apart support arms 58 which carry at their other free ends in each case a second shaft 60 to which the body 51 of the clamping unit 50 is pivotally mounted with lateral support arms 51a, as beside Fig. 3 in particular also Fig. 2 reveals.

Am anderen Ende 54b des Doppelhebels 54 ist eine zweite Rolle 64 gelagert, die entlang des Umfanges einer ersten Kurvenscheibe 66 läuft, die an einer dritten Welle 68 drehfest befestigt ist. Die dritte Welle 68 wird von einem im einzelnen nicht dargestellten Motor angetrieben.At the other end 54b of the double lever 54, a second roller 64 is mounted, which runs along the circumference of a first cam 66 which is rotatably mounted on a third shaft 68. The third shaft 68 is driven by a motor, not shown in detail.

An dieser Stelle sei der Vollständigkeit halber noch erwähnt, dass die erste Welle 56, die zweiten Wellen 60 und die dritte Welle 68 parallel zueinander und dabei die beiden zweiten Wellen 60 koaxial zueinander angeordnet sind, wie insbesondere Fig. 2 zeigt.At this point, for the sake of completeness, it should be mentioned that the first shaft 56, the second shafts 60 and the third shaft 68 are arranged parallel to one another and the two second shafts 60 are arranged coaxially relative to one another, as shown particularly in FIG.

Wie Fig. 3 erkennen lässt, hat die erste Kurvenscheibe 66 eine Art Birnenform mit einem teilkreisförmigen ersten Abschnitt 66a und einem den Radius vergrößernden, ausbauchenden bzw. vorspringenden zweiten Abschnitt 66b. Eine Rotation der ersten Kurvenscheibe 66 bewirkt eine reziproke Bewegung des Doppelhebels 54 um die erste Welle 56, was zu einer abwechselnd zur Transportvorrichtung 40 hinführenden und von dieser wegführenden Bewegung der Klemmbackeneinheit 44 führt. In der in Fig. 3 gezeigten Betriebsstellung weist die Klemmbackeneinheit 44 den geringsten Abstand zur Transportvorrichtung 40 auf mit der Folge, dass der zu diesem Zeitpunkt noch in der Transportvorrichtung 40 liegende Drahtkamm von der Klemmbackeneinheit 44 in der zuvor beschriebenen Weise gegriffen werden kann. Diese Betriebsstellung wird dadurch erreicht, dass die Rolle 64 am zweiten Ende 54b des Doppelhebels 54 am zweiten Abschnitt 66b der ersten Kurvenscheibe 66 anliegt, wie Fig. 3 ebenfalls erkennen lässt. Damit sich die Rolle 64 stets in berührendem Eingriff mit der ersten Kurvenscheibe 66 befindet, ist eine im einzelnen nicht näher dargestellte Vorspanneinrichtung vorgesehen, die den Doppelhebel 54 entsprechend vorspannt.As can be seen in FIG. 3, the first cam 66 has a kind of pear shape with a part-circular first section 66a and a radius-enlarging, bulging or projecting second section 66b. A rotation of the first cam 66 causes a reciprocal movement of the double lever 54 about the first shaft 56, which leads to an alternately to the transport device 40 leading away and away from this movement of the jaw unit 44. In the operating position shown in Fig. 3, the jaw unit 44 has the smallest distance to the transport device 40, with the result that the present at this time still in the transport device 40 wire comb can be gripped by the jaw unit 44 in the manner described above. This operating position is achieved in that the roller 64 at the second end 54b of the double lever 54 at the second portion 66b of the first cam 66 is applied, as Fig. 3 also reveals. So that the Roller 64 is always in touching engagement with the first cam 66, a biasing device not shown in detail is provided which biases the double lever 54 accordingly.

Bei fortgesetzter Rotation gelangt dann die Rolle 64 am zweiten Ende 54b des Doppelhebels 54 auf den teilkreisförmigen ersten Abschnitt 66a der ersten Kurvenscheibe 66, wodurch sich der Abstand zur dritten Welle 68 deutlich verringert. Dies bewirkt eine Schwenkbewegung des Doppelhebels 54 derart, dass dessen erstes Ende 54a von der Transportvorrichtung 40 wegbewegt wird. Dabei nimmt der Doppelhebel 54 über das Scharnier 53 den Schieber 52 der Klemmeinheit 50 entsprechend mit. Dies wiederum hat zur Folge, dass die Klemmbackeneinheit 44 von der Transportvorrichtung 40 entfernt wird. Da der Drahtkamm 42 von der Klemmbackeneinheit 44 aufgenommen worden ist, wird die Transportvorrichtung 40 frei, um den nächsten Drahtkamm in die Drahtkamm-Einziehvorrichtung 36 zu transportieren.With continued rotation then enters the roller 64 at the second end 54b of the double lever 54 on the part-circular first portion 66a of the first cam 66, whereby the distance to the third shaft 68 is significantly reduced. This causes a pivotal movement of the double lever 54 such that its first end 54a is moved away from the transport device 40. In this case, the double lever 54 takes over the hinge 53, the slider 52 of the clamping unit 50 accordingly. This in turn has the consequence that the clamping jaw unit 44 is removed from the transport device 40. Since the wire comb 42 has been picked up by the jaw unit 44, the transport device 40 is released to transport the next wire comb into the wire crimper 36.

Durch die Bewegung der Klemmbackeneinheit 44 von der in Fig. 3 gezeigten ersten Stellung in die in Fig. 4 gezeigte zweite Stellung wird die Klemmbackeneinheit 44 und somit der von dieser gehaltene, noch offene Drahtkamm 42 in Richtung auf den Block 29 transportiert.By the movement of the jaw unit 44 from the first position shown in Fig. 3 in the second position shown in Fig. 4, the jaw unit 44 and thus held by this, still open wire comb 42 is transported in the direction of the block 29.

Während der Schwenkbewegung zwischen den in den Figuren 3 und 4 gezeigten Schwenkstellungen verbleibt der Tragarm 58 gegenüber der Transportvorrichtung 40 und dem Block 29 in unveränderter Relativposition.During the pivotal movement between the pivot positions shown in Figures 3 and 4, the support arm 58 relative to the transport device 40 and the block 29 remains in the same relative position.

Wie Fig. 5 in Verbindung mit Fig. 2 erkennen lässt, ist ferner an der ersten Welle 56 drehfest ein zweiter Doppelhebel 72 befestigt, an dem ein erster Tragarm 72a und ein zweiter Tragarm 72b vorgesehen sind. Der erste Tragarm 72a trägt eine erste Rolle 74, die entlang des Umfanges einer zweiten Kurvenscheibe 76 läuft, welche auf der dritten Welle 68 drehfest sitzt. Der zweite Tragarm 72b trägt eine zweite Rolle 78, die entlang des Umfanges einer dritten Kurvenscheibe 80 läuft, welche ebenfalls auf der dritten Welle 68 drehfest befestigt ist. Auch der Tragarm 58 wird durch eine nicht näher dargestellte Vorspanneinrichtung so in Richtung auf die zweiten und dritten Kurvenscheiben 76 und 80 vorgespannt, dass sich die Rollen 74 und 78 mit den zweiten und dritten Kurvenscheiben 76 und 80 stets in berührendem Eingriff befinden.As can be seen in FIG. 5 in connection with FIG. 2, a second double lever 72 is also secured against rotation on the first shaft 56, to which a first support arm 72a and a second support arm 72b are provided. The first support arm 72a carries a first roller 74 which runs along the circumference of a second cam 76 which is non-rotatably mounted on the third shaft 68. The second support arm 72b carries a second roller 78, which runs along the circumference of a third cam 80, which is also rotatably mounted on the third shaft 68. Also, the support arm 58 is not closer by a biasing means biased toward the second and third cams 76 and 80 so that the rollers 74 and 78 are always in touching engagement with the second and third cams 76 and 80.

Durch Rotation der zweiten und dritten Kurvenscheiben 76 und 80 wird der Doppelhebel 72 einer Schwenkbewegung unterworfen, die auf die erste Welle 56 übertragen wird, wodurch nun wiederum der Tragarm 58 einer entsprechenden Schwenkbewegung unterworfen. wird. Dies hat zur Folge, dass nunmehr die gesamte Klemmeinheit 50 von der Transportvorrichtung 40 wegbewegt wird. Dabei wird der von der Klemmeinheit 50 gehaltene Drahtkamm 42 so mitgenommen, dass dessen eines Kammsegment 42a in die Lochungen 29a des Blockes eingeführt wird, wie Fig. 5 erkennen lässt. Der Schwenkweg der Klemmeinheit 50 ist in Fig. 5 durch eine mit "X" bezeichnete strichpunktierte Linie angedeutet. Wie Fig. 5 gut erkennen lässt, ist die gesamte Anordnung so getroffen und insbesondere der Radius, der durch den Abstand zwischen den Mittelachsen der Wellen 56 und 60 gebildet ist, so gewählt, dass das vorlaufende Kammsegment 42a des Drahtkammes 42 zur Lochung 29a ausgerichtet ist und sich deshalb sauber einführen lässt.By rotation of the second and third cams 76 and 80, the double lever 72 is subjected to a pivotal movement, which is transmitted to the first shaft 56, whereby in turn subjected to the support arm 58 of a corresponding pivoting movement. becomes. This has the consequence that now the entire clamping unit 50 is moved away from the transport device 40. In this case, the wire comb 42 held by the clamping unit 50 is entrained so that a comb segment 42a thereof is inserted into the perforations 29a of the block, as shown in FIG. The pivoting path of the clamping unit 50 is indicated in Fig. 5 by a dot-dash line designated "X". As can be clearly seen in Fig. 5, the entire arrangement is made and, in particular, the radius formed by the distance between the center axes of the shafts 56 and 60 is selected so that the leading comb segment 42a of the wire comb 42 is aligned with the perforation 29a and therefore can be introduced cleanly.

Dabei verbleibt der Körper 51 der Klemmeinheit 50 weiterhin in unveränderter Relativposition zum Tragarm 58.In this case, the body 51 of the clamping unit 50 remains in unchanged relative position to the support arm 58th

Wie bereits zuvor anhand von Fig. 3 beschrieben worden ist, ist die Klemmeinheit 50 mit ihrem Körper 51 über zweite Wellen 60 am Tragarm 58 schwenkbar gelagert. Zur Steuerung der Schwenkbewegung gegenüber den Tragarmen 58 ist an diesen jeweils eine Zahnstange 82 angeordnet, die in Richtung ihrer Längserstreckung verschieblich gelagert ist (vgl. hierzu auch Fig. 2). Jede Zahnstange 82 befindet sich mit ihrer in den Figuren nicht näher bezeichneten Zahnreihe in Eingriff mit einem ebenfalls in den Figuren nicht näher bezeichneten Zahnkranz, der entlang des Umfanges der zweiten Wellen 60 ausgebildet ist. Um bei longitudinaler Bewegung der beiden Zahnstangen 82 den Körper 51 der Klemmeinheit 50 mit einer entsprechenden Schwenkbewegung zu beaufschlagen, sind die zweiten Wellen 60 an den seitlichen Armen 51a des Körpers 51 drehfest befestigt und in den Tragarmen 58 drehbar gelagert. Ferner weist die erste Welle 56 Zahnkranzabschnitte 56a auf, die sich jeweils mit der Zahnreihe einer Zahnstange 82 ebenfalls in Eingriff befinden. Konstruktive Einzelheiten des Tragarmes 58 und insbesondere die daran verschieblich gelagerte Zahnstange 82 sind in Fig. 6 erkennbar. An dieser Stelle sei allerdings darauf hingewiesen, dass die in Fig. 6 dargestellten Einzelheiten des Tragarmes 58 in den Fig. 2 bis 5 aus Gründen der Übersichtlichkeit weggelassen sind.As has already been described above with reference to FIG. 3, the clamping unit 50 is pivotally mounted with its body 51 via second shafts 60 on the support arm 58. To control the pivoting movement relative to the support arms 58, a toothed rack 82 is arranged on each of these and is mounted displaceably in the direction of its longitudinal extent (cf., also FIG. 2). Each rack 82 is located with its unspecified in the figures row of teeth in engagement with a likewise unspecified in the figures sprocket, which is formed along the circumference of the second shaft 60. For longitudinal movement of the two racks 82, the body 51 of the clamping unit 50 with a to apply corresponding pivoting movement, the second shafts 60 are rotatably attached to the side arms 51 a of the body 51 and rotatably supported in the support arms 58. Further, the first shaft 56 has sprocket portions 56 a, which are also in engagement with the row of teeth of a rack 82, respectively. Constructive details of the support arm 58 and in particular the rack 82 displaceably mounted thereon can be seen in FIG. It should be noted, however, that the details shown in Fig. 6 of the support arm 58 in FIGS. 2 to 5 are omitted for reasons of clarity.

Wie Fig. 6 schließlich ferner erkennen lässt, ist an einem stationären Element 90 mit Hilfe einer Gelenkwelle 92 ein dritter Doppelhebel 94 verschwenkbar gelagert. Der dritte Doppelhebel 94 weist zwei, parallele Arme 94a und 94b auf. Dabei trägt der erste Arm 94a eine erste Rolle 96, die entlang des Umfanges einer vierten Kurvenscheibe 98 läuft, welche drehfest an der dritten Welle 68 befestigt ist. Der dem Tragarm 58 zugewandte zweite Arm 94b trägt ebenfalls Weine Rolle 100, die entlang des Umfanges einer fünften Kurvenscheibe 102 läuft; welche ebenfalls drehfest auf der dritten Welle 68 sitzt. Auch hier ist die Anordnung so getroffen, dass die Rollen 96, 100 stets in rollendem Eingriff mit den vierten und fünften Kurvenscheiben 98 und 102 verbleiben.As finally shown in FIG. 6, a third double lever 94 is mounted pivotably on a stationary element 90 with the aid of a cardan shaft 92. The third double lever 94 has two parallel arms 94a and 94b. In this case, the first arm 94a carries a first roller 96, which runs along the circumference of a fourth cam 98, which is non-rotatably attached to the third shaft 68. The second arm 94b facing the support arm 58 also carries wines roll 100 which runs along the circumference of a fifth cam 102; which also rotatably on the third shaft 68 is seated. Again, the arrangement is such that the rollers 96, 100 always remain in rolling engagement with the fourth and fifth cams 98 and 102.

Der dem zweiten Arm 94b benachbarte Randabschnitt des dritten Doppelarmes 94 ist mit einem Zahnsegment 94c versehen, das sich ebenfalls in Eingriff mit einer der beiden Zahnkranz-Abschnitte 56a der ersten Welle 56 befindet. Das Zahnsegment 94c ist leicht gekrümmt und folgt dabei einem Kreisbogen, dessen Mittelpunkt mit der Mittelachse der Gelenkwelle 92 zusammenfällt, wie Fig. 6 erkennen lässt.The second arm 94b adjacent edge portion of the third double arm 94 is provided with a toothed segment 94c, which is also in engagement with one of the two sprocket portions 56a of the first shaft 56. The toothed segment 94c is slightly curved and follows a circular arc whose center coincides with the central axis of the propeller shaft 92, as shown in FIG. 6 reveals.

Die Rotation der vierten und fünften Kurvenscheiben 98 und 102 bewirkt eine reziproke Schwenkbewegung des dritten Doppelhebels 94 um die Gelenkwelle 92. Dabei wird auch das Zahnsegment 94c einer entsprechenden reziproken Bewegung unterworfen, welches diese Bewegung über die Welle 56 auf die Zahnstangen 82 überträgt. Die entsprechend in reziproke Längsbewegung versetzten Zahnstangen 82 übertragen diese Bewegung wiederum auf die zweiten Wellen 60, wodurch die Klemmeinheit 50 einer entsprechenden Schwenkbewegung unterworfen wird.The rotation of the fourth and fifth cams 98 and 102 causes a reciprocal pivoting movement of the third double lever 94 about the pivot shaft 92. In this case, the sector gear 94c is subjected to a corresponding reciprocal movement, which this movement over the shaft 56 transmits to the racks 82. The corresponding offset in reciprocal longitudinal movement racks 82 in turn transmit this movement to the second shaft 60, whereby the clamping unit 50 is subjected to a corresponding pivoting movement.

Die vierten und fünften Kurvenscheiben 98 und 102 sind so gestaltet, dass während der in den Figuren 3 bis 5 gezeigten Betriebsstellungen eine Schwenkbewegung der Klemmeinheit 50 um die zweiten Wellen 60 gegenüber den Tragarmen 58 unterbleibt, sondern erst beim Übergang der Betriebsstellung gemäß Fig. 5 in die in Fig. 6 gezeigte Betriebsstellung stattfindet. Dann werden nämlich die Zahnstangen 82 in entsprechende longitudinale Bewegung versetzt, wodurch die gesamte Klemmeinheit 50 gegenüber den Tragarmen 58 um die zweiten Wellen 60 in die in Fig. 6 gezeigte Stellung verschwenkt wird. Während dieser Schwenkbewegung der Klemmeinheit 50 fällt die Längsachse der zweiten. Wellen 60 etwa mit der Mittelpunktsachse des teilkreisförmigen Kammsegmentes 42a zusammen. Dies hat zur Folge, dass während des Verschwenkens der Klemmeinheit 50 der Drahtkamm 42 mit seinem ersten Kammsegment 42a um dessen Mittelpunktsachse gedreht und dadurch das vorlaufende erste Kammsegment 42a fluchtend und somit sauber in die Lochung 29a eingedreht wird.The fourth and fifth cams 98 and 102 are designed so that during the operating positions shown in Figures 3 to 5, a pivoting movement of the clamping unit 50 about the second shaft 60 relative to the support arms 58 is omitted, but only at the transition of the operating position shown in FIG. 5 in the operating position shown in Fig. 6 takes place. Then, namely, the racks 82 are offset in corresponding longitudinal movement, whereby the entire clamping unit 50 is pivoted relative to the support arms 58 about the second shaft 60 in the position shown in Fig. 6. During this pivotal movement of the clamping unit 50, the longitudinal axis of the second falls. Shafts 60 approximately with the center axis of the part-circular comb segment 42 a together. This has the consequence that during the pivoting of the clamping unit 50 of the wire comb 42 is rotated with its first comb segment 42a about its center axis and thereby the leading first comb segment 42a is aligned and thus screwed cleanly into the perforation 29a.

Dies hat zur Folge, dass der mit seinem ersten Kammsegment 42a bereits in die Lochung 29a gesteckte Drahtkamm gegenüber der Stellung von Fig. 5 weiter in die Lochung 29a eingedreht und dann durch diese hindurchgezogen wird.As a result, the wire comb already inserted into the perforation 29a with its first comb segment 42a is further screwed into the perforation 29a relative to the position of FIG. 5 and then pulled through it.

Anschließend öffnet der Pneumatikzylinder 49 die Klemmbacken 48, wodurch die Klemmeinheit 50 von dem Drahtkamm 42 gelöst wird, und der Drahtkamm 42 bleibt aufgrund seines durch die Lochung 29a hindurch gesteckten ersten Kammsegments 42a nun am Block 29 hängen.Subsequently, the pneumatic cylinder 49 opens the jaws 48, whereby the clamping unit 50 is released from the wire comb 42, and the wire comb 42 now remains hanging on the block 29 due to its first comb segment 42a inserted through the perforation 29a.

Bei fortgesetzter Rotation der Kurvenscheiben 98 und 102 wird der dritte Doppelhebel 94 einer weiteren Schwenkbewegung derart unterworfen, dass die Zahnstangen 82 über die zweiten Wellen 60 die Klemmeinheit 50 in die in Fig. 4 gezeigte Stellung zurückschwenken, bevor dann anschließend durch Wirkung des ersten Doppelhebels 54 der Schieber 52 und somit die daran sitzende Klemmbackeneinheit 44 in Richtung auf den zwischenzeitlich von der Transportvorrichtung 40 angelieferten neuen Drahtkamm 42 und somit in die in Fig. 3 gezeigte Betriebsstellung vorgeschoben werden, um dann diesen neuen Drahtkamm 42 aufzunehmen.With continued rotation of the cams 98 and 102, the third double lever 94 is subjected to further pivotal movement such that the racks 82 via the second shafts 60, the clamping unit 50 pivot back into the position shown in Fig. 4, before then then by action of the first double lever 54 of the slider 52 and thus the seated jaw unit 44 in the direction of the meantime delivered by the transport device 40 new wire comb 42 and thus be advanced to the operating position shown in Fig. 3, to then receive this new wire comb 42.

Die zuvor beschriebene Drahtkamm-Einziehvorrichtung 36 dient im dargestellten Ausführungsbeispiel somit lediglich zum Einhängen der noch offenen Drahtkämme 42, wobei die Klemmeinheit 50, wie aus der vorangegangenen Beschreibung erkennbar ist, nicht nur zum Greifen, sondern auch zum Verschwenken der Drahtkämme 42 verwendet wird.The wire comb retracting device 36 described above thus serves only for suspending the still open wire combs 42 in the illustrated embodiment, wherein the clamping unit 50, as can be seen from the foregoing description, not only for gripping, but also for pivoting the wire combs 42 is used.

Zum Schließen der noch offenen Drahtkämme 42 ist dagegen eine Drahtkamm-Schließvorrichtung vorgesehen, die in den Figuren 2 und 7 im einzelnen dargestellt und mit dem Bezugszeichen 38 gekennzeichnet ist. Gewöhnlich ist die Drahtkamm-Schließvorrichtung 38 benachbart zur zuvor beschriebenen Drahtkamm-Einziehvorrichtung angeordnet. Wie Fig. 2 erkennen lässt, ist im dargestellten Ausführungsbeispiel die in der rechten Hälfte von Fig. 2 gezeigte Drahtkamm-Schließvorrichtung 38 gegenüber der in der linken Hälfte von Fig. 2 gezeigten Drahtkamm-Einziehvorrichtung 36 so angeordnet, dass der Block 29 mit dem darin eingehängten Drahtkamm 42 lediglich in Richtung der Längserstreckung des Drahtkammes 42 von der Drahtkamm-Einziehvorrichtung 36 in die Drahtkamm-Schließvorrichtung 38 transportiert zu werden braucht, wodurch der Transportweg verhältnismäßig kurz gehalten werden kann. Somit fluchten im dargestellten Ausführungsbeispiel die Positionen des Drahtkammes 42 in der Drahtkamm-Einziehvorrichtung 36 und in der Drahtkamm-Schließvorrichtung 38 hinsichtlich der Längsachse miteinander.For closing the still open wire combs 42, however, a wire comb-closing device is provided, which is shown in detail in Figures 2 and 7 and designated by the reference numeral 38. Usually, the wire comb closing device 38 is disposed adjacent to the wire comb retractor described above. As shown in FIG. 2, in the illustrated embodiment, the wire comb closing device 38 shown in the right half of FIG. 2 is disposed opposite to the wire crimper 36 shown in the left half of FIG. 2 so that the block 29 with the therein hinged wire comb 42 only needs to be transported in the direction of the longitudinal extent of the wire comb 42 of the wire comb-Einziehvorrichtung 36 in the wire comb-closing device 38, whereby the transport can be kept relatively short. Thus, in the illustrated embodiment, the positions of the wire comb 42 in the wire comb retractor 36 and in the wire comb fastener 38 are aligned with each other with respect to the longitudinal axis.

Einzelheiten der Drahtkamm-Schließvorrichtung 38 sind beispielhaft in Fig. 7 gezeigt. Die Ansicht von Fig. 7 besitzt die gleiche Perspektive wie die der Figuren 3 bis 6; d.h. auch in Fig. 7 ist der Drahtkamm 42 in Stirnansicht dargestellt und erstreckt sich somit in seiner Längsausdehnung rechtwinklig zur Bildebene.Details of the wire comb closing device 38 are shown by way of example in FIG. The view of FIG. 7 has the same perspective as that of FIG FIGS. 3 to 6; ie, in Fig. 7, the wire comb 42 is shown in front view and thus extends in its longitudinal extent at right angles to the image plane.

Wie Fig. 7 erkennen lässt, weist die Drahtkamm-Schließvorrichtung 38 einen oberen ersten Schließbalken 108 auf. Dieser erste Schließbalken 108 ist an einem nicht dargestellten Lager gehaltert, welches erlaubt, dass der erste Schließbalken 108 entlang eines verhältnismäßig kurzen Hubweges in Richtung auf den Drahtkamm 42 und von diesem weg bewegbar ist, wobei die Bewegung durch einen ebenfalls nicht dargestellten Antrieb erzeugt wird. Der Bewegungshub des ersten Schließbalkens 108 muss lediglich so groß sein, dass bei Transport des Blockes 29 in die Drahtkamm-Schließvorrichtung 38 und aus dieser heraus eine Kollision mit dem Drahtkamm 42 vermieden wird.As can be seen in FIG. 7, the wire comb closing device 38 has an upper first closing bar 108. This first closing bar 108 is supported on a bearing, not shown, which allows the first closing bar 108 along a relatively short stroke in the direction of the wire comb 42 and away from it is movable, wherein the movement is generated by a drive, also not shown. The movement stroke of the first locking bar 108 only has to be so large that a collision with the wire comb 42 is avoided when the block 29 is transported into and out of the wire comb closing device 38.

Wie Fig. 7 ferner erkennen lässt, weist die Drahtkamm-Schließvorrichtung 38 ferner einen unteren zweiten Schließbalken 110 auf, der von einem Schlitten 112 gehalten wird. Dieser Schlitten 112 ist in nicht im einzelnen dargestellter Weise verschieblich gelagert, wodurch der zweite Schließbalken 110 in Richtung auf den Drahtkamm 42 und von diesem weg bewegbar ist. Der Hubweg des zweiten Schließbalkens 110 ist dabei deutlich größer als der des ersten Schließbalkens 108.Further, as shown in FIG. 7, the wire comb closing device 38 further includes a lower second closing beam 110 held by a carriage 112. This carriage 112 is slidably mounted in a manner not shown in detail, whereby the second closing bar 110 is movable in the direction of the wire comb 42 and away from it. The stroke of the second locking bar 110 is significantly greater than that of the first locking bar 108th

Für den reziproken Antrieb des Schlittens 112 ist dieser mit einem quer zu dessen Bewegungsrichtung verlaufenden Langloch 114 versehen, in dem eine Rolle 115 läuft, die an einem ersten Arm 116a eines Dreiarmhebels 116 drehbar gelagert ist. Der Dreiarmhebel 116 ist um eine Gelenkwelle 118 schwenkbar gelagert. An einem zweiten Arm 116b des Dreiarmhebels 116 ist eine Rolle 120 angeordnet, die entlang des Umfanges einer sechsten Kurvenscheibe 122 läuft. An einem dritten Arm 116c des Dreiarmhebels 116 ist eine weitere Rolle 124 drehbar gelagert, die entlang des Umfanges einer siebten Kurvenscheibe 126 läuft. Die sechsten und siebten Kurvenscheiben 122 und 126 sind wie die anderen bereits beschriebenen Kurvenscheiben drehfest an der dritten Welle 68 (vgl. Fig. 2) befestigt und werden durch Drehung dieser Welle 68 in entsprechende Rotation versetzt. Dabei ist die gesamte Anordnung so getroffen, dass bei Rotation der Welle 68 und somit der Kurvenscheiben 122 und 126 die Rollen 120 und 124 stets in berührendem Eingriff mit den Kurvenscheiben 122, 126 bleiben.For the reciprocal drive of the carriage 112, this is provided with a transverse to the direction of movement extending slot 114 in which a roller 115 runs, which is rotatably mounted on a first arm 116 a of a three-armed lever 116. The three-arm lever 116 is pivotally mounted about a hinge shaft 118. On a second arm 116b of the three-arm lever 116, a roller 120 is arranged, which runs along the circumference of a sixth cam 122. On a third arm 116 c of the three-arm lever 116, a further roller 124 is rotatably mounted, which runs along the circumference of a seventh cam 126. The sixth and seventh cams 122 and 126, like the other cams already described, are fixed against rotation on the third shaft 68 (see Fig. 2) and are passed through Rotation of this shaft 68 is placed in corresponding rotation. In this case, the entire arrangement is such that upon rotation of the shaft 68 and thus of the cams 122 and 126, the rollers 120 and 124 always remain in touching engagement with the cams 122, 126.

Bei Rotation der Kurvenscheiben 122, 126 wird der Dreiarmhebel 116 und somit dessen erster Arm 116a in reziproke Schwenkbewegung versetzt, was zu einer reziproken Längsbewegung des Schlittens 112 und somit des daran befestigten zweiten Schließbalkens 110 führt.Upon rotation of the cams 122, 126, the three-arm lever 116 and thus its first arm 116a is set in reciprocal pivotal motion, resulting in reciprocal longitudinal movement of the carriage 112 and thus the second striker 110 attached thereto.

Nachdem der Block 29 mit dem darin eingehängten Drahtkamm 42 in die Drahtkamm-Schließvorrichtung 38 eingefahren worden ist, wird zunächst der obere erste Schließbalken 108 soweit abgesenkt, bis er am ersten Kammsegment 42a des noch offenen Drahtkammes 42 anliegt. Dabei oder anschließend wird durch entsprechende Rotation der dritten Welle 68 und somit der Kurvenscheiben 122, 126 der Dreiarmhebel 116 so betätigt, dass der Schlitten 112 und dadurch der von diesem getragene zweite Schließbalken 110 in Richtung auf den Drahtkamm 42 verfahren wird, dadurch in Eingriff mit dem zweiten Kammsegment 42b gelangt und diesen in Richtung auf das erste Kammsegment 42a drückt; bis die freien Enden beider Kammsegmente 42a, 42b im Wesentlichen übereinanderliegen und auf diese Weise der Drahtkamm 42 geschlossen ist, wobei der erste Schließbalken 108 als Widerlager dient.After the block 29 has been retracted with the wire comb 42 suspended therein in the wire comb closing device 38, the upper first closing bar 108 is first lowered so far, until it rests against the first comb segment 42 a of the still open wire comb 42. In this process, or subsequently, by corresponding rotation of the third shaft 68 and thus of the cams 122, 126, the three-arm lever 116 is actuated such that the carriage 112 and thereby the second closing beam 110 carried thereby is moved in the direction of the wire comb 42, thereby engaging enters the second comb segment 42b and pushes it in the direction of the first comb segment 42a; until the free ends of both comb segments 42a, 42b substantially overlie each other and in this way the wire comb 42 is closed, wherein the first closing bar 108 serves as an abutment.

Gegebenenfalls kann die Drahtkamm-Schließvorrichtung 38 noch ein zusätzliches Ausrichtelement, das gewöhnlich als Schwenkleiste ausgeführt ist, aufweisen, um den Drahtkamm 42 in eine gewünschte Position auszurichten, bevor er durch Eingriff mit den Schließbalken 108, 110 in der zuvor beschriebenen Weise geschlossen wird. Ein solches zusätzliches Ausrichtelement ist in den Figuren aus Gründen der Übersichtlichkeit nicht dargestellt.Optionally, the wire comb closing device 38 may further comprise an additional alignment member, which is usually formed as a pivot bar, to align the wire comb 42 to a desired position before being closed by engagement with the striker bars 108, 110 in the manner previously described. Such an additional alignment element is not shown in the figures for reasons of clarity.

Nach Schließen des Drahtkammes 42 wird der Block durch eine ebenfalls nicht dargestellte Transportvorrichtung aus der Drahtkamm-Schließvorrichtung 38 zur Weiterverarbeitung entfernt.After closing the wire comb 42, the block is removed by a transport device, also not shown, from the wire comb closing device 38 for further processing.
