Two endless screws (14 and 18) provide for the feed of endless material for the clamps (5) to the cutting station (9) and thereafter of the clamps (5') to the binding station (12). At least one motor (20) and at least one coupling (23) provide for the intermittent driving of the endless screws.

Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Binden von gelochten Bögen durch eine aus Draht gebogene Fingerbindung, im übrigen mit den im Oberbegriff von Anspruch 1 genannten Merkmalen.The present invention relates to a device for binding perforated sheets by means of a finger binding bent from wire, moreover with the features mentioned in the preamble of claim 1.

Durch die US-PS 4 155 134 ist eine Vorrichtung dieser Art bekannt geworden, bei der Endlosmaterial der Fingerbindung durch eine Art Kettenrad in eine als Zwischenspeicher dienende Schleife gefördert wird, aus der durch ein weiteres Kettenrad das Endlosmaterial einer Schneidvorrichtung zugeführt wird. Anschließend wird je ein abgeschnittenes Stück der Fingerbindung durch SchlieBbacken in die Lochungen des Bindeguts eingedrückt. Die bekannte Vorrichtung hat durch den Zwischenspeicher einen erheblichen Raumbedarf. Ferner haben Kettenräder ebenso wie Zahnriemen den Nachteil, daß sie das Fingerbindungsmaterial nur dann einwandfrei fördern, wenn dessen Teilung, d.h. die Abstände zwischen den einzelnen Fingern,nur innerhalb sehr geringer Toleranzen schwanken. Bei größeren Abweichungen wird das Material verformt, und es müssen Vorkehrungen getroffen werden, daß verformte Materialstücke aus der Vorrichtung entfernt werden. Mit Rücksicht darauf, daß die Lochung des Bindeguts eine relativ große Teilungstoleranz der Fingerbindung zuläßt, muß hier ein unnötiger Aufwand entweder zur Kleinhaltung der Toleranz oder zum E'ntfernen zerstörter Bindungsstücke getrieben werden.A device of this type has become known from US Pat. No. 4,155,134, in which the endless material of the finger binding is conveyed through a type of sprocket into a loop serving as a buffer, from which the continuous material is fed to a cutting device through a further sprocket. Then a cut piece of the finger binding is pressed into the perforations of the binding material by means of closing jaws. The known device requires a considerable amount of space due to the intermediate storage. Furthermore, sprockets and toothed belts have the disadvantage that they only properly convey the finger binding material if its division, ie the distances between the individual fingers, fluctuate only within very small tolerances. With larger deviations, the material is deformed and precautions must be taken be met that deformed pieces of material are removed from the device. Considering the fact that the perforation of the Bindeguts allows a relatively large pitch tolerance of the finger bond, an unnecessary expense either 'emove for small attitude of tolerance or e destroyed binding pieces must be driven here.

Durch die vorliegende Erfindung soll eine Vorrichtung der genannten Art geschaffen werden, die einerseits wenig Raum beansprucht und andererseits geeignet ist, Bindungsmaterial mit hoher Teilungstoleranz zu verarbeiten.The present invention is intended to create a device of the type mentioned which on the one hand takes up little space and on the other hand is suitable for processing binding material with a high division tolerance.

Diese Aufgabe wird gemäß Anspruch 1 gelöst, auf dessen Wortlaut im folgenden Bezug genommen wird.This object is achieved according to claim 1, the wording of which reference is made below.

Zum Fördern dienen hiernach zwei Schnecken, von denen die eine zur Schneidvorrichtung fördert, die andere zur Bindestation.Führungsteile, die der zweiten Schnecke unmittelbar benachbart sind, sorgen für eine einwandfreie Zuführung der Bindungsstücke zur Bindestation. Dort werden die Bindungsstücke mit Hilfe von Schließbacken zusammengedrückt, so daß die Finger der Bindungsstücke in die Lochung der Bögen eingreifen und die Bögen zusammenhalten. Die Antriebe sind so ausgestaltet, daß sie während des Schneidvorganges und während des Bindevorganges beide stillgesetzt werden können. Zusätzlich ist dafür gesorgt, daß die erste Schnecke während eines Fördertaktes der zweiten Schnecke stillgesetzt wird, nämlich dann, wenn die zweite Schnecke ein abgetrenntes Bindungsstück zur Bindestation vorschiebt.According to this, two screws are used for conveying, one of which conveys to the cutting device, the other to the binding station. There the binding pieces are pressed together with the help of locking jaws, so that the fingers of the binding pieces engage in the perforation of the arches and hold the arches together. The drives are designed so that they can both be stopped during the cutting process and during the binding process. In addition, it is ensured that the first screw is stopped during a conveying cycle of the second screw, namely when the second screw advances a separated binding piece to the binding station.

Schnecken haben den Vorteil, daß sie das aus Draht gebogene Bindungsmaterial schonend ergreifen und fördern, auch dann, wenn dessen Teilung innerhalb großer Toleranzen schwankt. Das Material wird von einer Schnecke niemals gegen einen Führungsteil gedrückt und zusammengequetscht.Snails have the advantage that they gently grip and convey the binding material bent from wire, even if its division fluctuates within large tolerances. The material is never pressed against a guide part by a screw and squeezed together.

Durch eine Weiterbildung gemäß Anspruch 2 kann für einen besonders schonenden Anfangseingriff gesorgt werden.Through a further development according to claim 2, a particularly gentle initial intervention can be ensured.

Neben der zweiten Schnecke können sowohl Schließbacken als auch gesonderte Führungsteile für die abgetrennten Bindungsstücke vorgesehen sein. Nach Anspruch 3 läßt sich die Vorrichtung jedoch dadurch vereinfachen, daß die Führungsteile zugleich die Schließbacken bilden.In addition to the second screw, both closing jaws and separate guide parts can be provided for the separated binding pieces. According to claim 3, however, the device can be simplified in that the guide parts also form the closing jaws.

Nach Anspruch 4 läßt sich dafür sorgen, daß die Schließbacken einerseits der Schnecke sehr dicht benachbart sein können, wie es für ihre Führungsfunktion erforderlich ist, daß aber andererseits ihre Schließbewegung durch die Schnecke nicht behindert wird.According to claim 4, it can be ensured that the closing jaws on the one hand can be very closely adjacent to the screw, as is necessary for their guiding function, but on the other hand that their closing movement is not hindered by the screw.

Während nach Anspruch 5 zwei getrennte motorische Antriebe für die beiden Schnecken vorgesehen sein können, läßt sich vorzugsweise nach Anspruch 6 für beide Schnecken ein gemeinsamer Antrieb vorsehen, der beide Schnecken gemeinsam antreibt oder stillsetzt, während durch eine Schaltkupplung dafür gesorgt wird, daß die erste Schnecke stillgesetzt wird, während die zweite Schnecke Bindungsstücke zur Bindestation vorschiebt.While two separate motor drives can be provided for the two screws according to claim 5, a common drive can preferably be provided for both screws according to claim 6, which drives or stops both screws together, while a clutch ensures that the first screw is stopped while the second screw feeds binding pieces to the binding station.

Figur 1 und 2 zeigen die an sich bekannten Fingerbindungen. Zunächst wird aus Draht das Grundmaterial 1 nach Figur 1 gebogen, das zunächst noch eben ist. Es hat einzelne Finger 3 in Form von Haarnadeln. Das Grundmaterial wird dann in die Form nach Figur 2 gebogen und stellt so die noch offene Fingerbindung 5 dar. Man erkennt wieder die Finger 3. Durch eine Schließvorrichtung soll die Fingerbindung zusammengedrückt werden, so daß die Finger in die Löcher eines Packens von Bögen eingreifen und den Packen dauerhaft zusammenhalten.Figures 1 and 2 show the known finger bindings. First, the basic material 1 according to FIG. 1 is bent out of wire, which is initially flat. It has individual fingers 3 in the form of hairpins. The base material is then bent into the shape according to FIG. 2 and thus represents the still open finger binding 5. The fingers 3 can be recognized again. The finger binding is to be pressed together by a closing device so that the fingers engage in the holes of a pack of sheets and keep the packs together permanently.

Figur 3 und 4 zeigen eine Ausführungsform einer Vorrichtung nach der Erfindung. Die Vorrichtung hat eine Schneidvorrichtung 9 und eine Bindestation 12. Zum Fördern des Endlosmaterials der Fingerbindung 5, das von einer nicht dargestellten Rolle abläuft, zur Schneidvorrichtung 9 dient eine erste Schnecke 14, die mit einer ortsfesten Führungsschiene 16 od.dgl. zusammenarbeitet. Zum Fördern abgetrennter Bindungsstücke 5' zur Bindestation 12 dient eine zweite Schnecke 18. Beide Schnecken haben spitz zulaufende, d. h. sich gegen ihr Ende im Radius verjüngende Anfänge 19, wodurch ein schonender Eingriff gewährleistet ist.Figures 3 and 4 show an embodiment of a device according to the invention. The device has a cutting device 9 and a binding station 12. A first screw 14, which is connected to a stationary guide rail 16 or the like, is used to convey the continuous material of the finger binding 5, which runs from a roll (not shown), to the cutting device 9. works together. A second screw 18 is used to convey separated binding pieces 5 ′ to the binding station 12. Both screws have tapering, ie. H. beginnings 19 tapering towards its end in the radius, thereby ensuring a gentle intervention.

Die Schnecken sind mit einem intermittierenden Antrieb ausgerüstet, der in verschiedener Weise ausgestaltet sein kann. Er weist mindestens einen Antriebsmotor 20 auf. Es können zusätzlich eine oder mehrere Schaltkupplungen 22, 23 vorgesehen sein.The screws are equipped with an intermittent drive, which can be designed in different ways. It has at least one drive motor 20. One or more clutches 22, 23 can additionally be provided.

Die Bindestation 12 hat einen Tisch 25 mit einem Anschlag 26, der gegen die zweite Schnecke 18 verstellbar und festsetzbar ist. Der Tisch dient zur Aufnahme des Bindeguts 28, d. h. gelochter Bögen. Der Anschlag 26 wird so eingestellt, daß die Löcher 30 des Bindeguts gegenüber der Kante 32 des Tisches vorstehen, so daß die Finger 3 der Fingerbindung in die Löcher eingreifen können.The binding station 12 has a table 25 with a stop 26 which is adjustable and fixable against the second screw 18. The table is used to hold the binding material 28, i. H. perforated sheets. The stop 26 is adjusted so that the holes 30 of the material project from the edge 32 of the table so that the fingers 3 of the finger binding can engage in the holes.

Zwischen der zweiten Schnecke 18 und dem Tisch 25 sind zwei Schließbacken 34 schwenkbar angeordnet. In der in Figur 4 dargestellten Lage dienen sie zugleich als Führungsteile, die ein abgetrenntes Bindungsstück 5' an der zweiten Schnekke 18 halten. Durch nicht dargestellte Mittel sind beide SchlieBbacken 34 um eine Achse 36 schwenkbar, die parallel zur Achse 38 der Schnecke 18 verläuft.Between the second screw 18 and the table 25, two locking jaws 34 are pivotally arranged. In the position shown in FIG. 4, they also serve as guide parts which hold a separated binding piece 5 'on the second screw 18. By means not shown, both locking jaws 34 can be pivoted about an axis 36 which runs parallel to the axis 38 of the screw 18.

Die Schließbacken 34 können auch um die Schneckenachse 38 schwenkbar angeordnet sein, sofern dies aus räumlichen Gründen zweckmäßig ist, oder um eine Achse, die zwischen der Schneckenachse 38 und dem Ort der Achse 36 liegt.The locking jaws 34 can also be arranged pivotably about the screw axis 38, if this is expedient for spatial reasons, or about an axis which lies between the screw axis 38 and the location of the axis 36.

Arbeitsweise:How it works:

Figur 5 zeigt schematisch die Lagen der Teile jeweils am Ende der vier Arbeitstakte eines Arbeitszyklus. Figur 6 zeigt die Tätigkeit der beiden Schnecken während der vier Arbeitstakte eines Arbeitszyklus.Figure 5 shows schematically the positions of the parts at the end of the four work cycles of a work cycle. Figure 6 shows the activity of the two screws during the four work cycles of a work cycle.

Im Takt 1 werden beide Schnecken angetrieben. Die erste Schnecke 14 fördert, unterstützt von der zweiten Schnecke 18, das Endlosmaterial der Fingerbindung 5 durch die geöffneten Messer der Schneidvorrichtung 9 nach rechts, bis sich rechts davon ein Stuck geeigneter Länge für die beabsichtigte Bindung befindet.Both screws are driven in cycle 1. The first screw 14, supported by the second screw 18, conveys the endless material of the finger binding 5 through the opened knives of the cutting device 9 to the right until there is a piece of suitable length for the intended binding on the right.

Im Takt 2 ruhen beide Schnecken, während die Schneidvorrichtung 9 ein Stück 5' der Fingerbindung abtrennt.In the cycle 2, both screws rest while the cutting device 9 cuts off a piece 5 'of the finger binding.

Im Takt 3 arbeitet nur die zweite Schnecke 18 und schiebt das Stück 5' bis in die richtige Lage am Tisch 25 vor, auf den das Bindegut 28, d. h. ein Packen gelochter Bögen ge- legt wird.Is inserted - in the clock 3, only the second screw 18 operates and pushes the piece 5 'to into the correct position on the table 25 in front, to which the binding material 28, ie, a packing perforated sheets ge.

Im Takt 4 ruhen beide Schnecken, während die SchlieBbacken 34 der Bindevorrichtung das Bindungsstück 5' zusammendrücken, so daB es Zylinderform annimmt, wobei die Finger 3 von unten her durch die Löcher 30 des Bindeguts greifen. In Figur 4 sind gestrichelt die SchlieBbacken 34 in ihrer Schließstellung und die in Zylinderform gebogene Fingerbindung 5" dargestellt.In cycle 4, both screws rest while the locking jaws 34 of the binding device compress the binding piece 5 'so that it assumes a cylindrical shape, the fingers 3 reaching from below through the holes 30 of the binding material. In Figure 4 the closing jaws 34 are shown in broken lines in their closed position and the finger binding 5 ″ bent in a cylindrical shape.

Damit ist ein Arbeitszyklus beendet. Während der nächste Zyklus mit Takt 1, wie beschrieben, beginnt, werden die gebundenen Bögen entfernt.This completes a work cycle. As the next cycle begins at bar 1, as described, the bound sheets are removed.

Varianten des intermittierenden AntriebesVariants of the intermittent drive

Wie Figur 6 zeigt, verhalten sich die beiden Schnecken in den Takten 1, 2 und 4 synchron, d. h. sie fördern im Takt 1 und ruhen in den Takten 2 und 4. Im Takt 3 dagegen arbeitet die zweite Schnecke während die erste ruht.As Figure 6 shows, the two snails behave synchronously in bars 1, 2 and 4, i. H. they promote in bar 1 and rest in bars 2 and 4. In bar 3, on the other hand, the second snail works while the first snail is at rest.

Ein Antrieb, der das leistet, kann in verschiedener Weise verwirklicht werden. Z. B. kann der Antriebsmotor 20 intermittierend arbeiten und eine Schaltkupplung 23 zwischen den beiden Schnecken vorgesehen sein. Bei eingerückter Kupplung verhalten sich beide Schnecken synchron (Takte 1, 2 und 4). Im Takt 3 ist die Kupplung ausgerückt, so daB nur die zweite Schnecke 18 angetrieben wird, während die erste Schnecke ruht.A drive that can do this can be implemented in various ways. For example, the drive motor 20 can work intermittently and a clutch 23 can be provided between the two screws. When the clutch is engaged, both screws behave synchronously (cycles 1, 2 and 4). In cycle 3, the clutch is disengaged so that only the second worm 18 is driven while the first worm is at rest.

Stattdessen können ein kontinuierlich laufender Motor 20 und eine zusätzliche Schaltkupplung 22 vorgesehen sein, die dann dazu dient, beide Schnecken gemeinsam stillzusetzen. Die Schaltkupplung 23 hat die oben beschriebene Funktion.Instead, a continuously running motor 20 and an additional clutch 22 can be provided, which then serves to shut down both screws together. The clutch 23 has the function described above.

Nach einer weiteren Variante kann ein Motor mittels Zahnrädern oder Riemen die zweite Schnecke 18 bei 40 antreiben.According to a further variant, a motor can drive the second worm 18 at 40 by means of gear wheels or belts.

Ist es aus räumlichen Gründen günstiger, so kann der Motor links neben der ersten Schnecke 14 sitzen. Diese Schnecke wird dann von der Kupplung 23 her durch eine Hohlwelle angetrieben, und der Motor treibt eine Welle an, die durch die Hohlwelle und die Kupllung hindurchläuft und die Schnecke 18 unmittelbar antreibt.If it is cheaper for spatial reasons, the motor can sit to the left of the first worm 14. This worm is then driven from the clutch 23 by a hollow shaft, and the motor drives a shaft which runs through the hollow shaft and the coupling and drives the worm 18 directly.

Nach einer weiteren Variante können beide Schnecken durch je einen intermittierend arbeitenden Motor angetrieben werden.According to a further variant, both screws can be driven by an intermittently working motor.
