Description

Die Erfindung betrifft ein Verfahren zum wahlweisen Positionieren von elektrischen Leitungen für das Ablängen der Leitungen und Bestücken der Enden mit elektrischen Verbindern. Die Erfindung betrifft zudem eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the optional positioning of electrical lines for cutting the lines to length and fitting the ends with electrical connectors. The invention also relates to an apparatus for performing the method.

Das Bestücken von elektrischen Leitungsstücken erfolgt in der Regel in Kabelkonfektionierautomaten. Zunächst wird eine elektrische Leitung von einer Kabeltrommel in Längsrichtung abgezogen und abgelängt und das abgelängte Leitungsstück im Kabelkonfektionierautomaten mit Greiferzangen im Quertransport zu verschiedenen oder gleichen Bearbeitungsstationen transportiert, an denen die Enden z. B. abisoliert und gecrimpt werden.Electrical line pieces are usually assembled in automatic cable assemblies. First, an electrical line is pulled from a cable drum in the longitudinal direction and cut to length and the cut piece of cable in the cable assembly machine with gripper tongs in cross transport to different or the same processing stations, at which the ends z. B. stripped and crimped.

Für das Wechseln von einem Leitungstyp zu einem anderen, z. B. von einer dünneren zu einer dickeren Leitung oder von einer schwarzen zu einer blauen Leitung bzw. zum wahlweisen Positionieren der Leitungen, gibt es Wechselvorrichtungen, in denen das vordere Leitungsende, bevor der Greifer der Ablängvorrichtung greift, zurückgezogen und ein anderes Leitungsende positioniert wird. Derartige Vorrichtungen arbeiten bei Kabelkonfektionierautomaten, die quertransportierende Greifer aufweisen, zufriedenstellend.For changing from one line type to another, e.g. B. from a thinner to a thicker line or from a black to a blue line or for optional positioning of the lines there are changing devices in which the front line end is withdrawn and another line end is positioned before the gripper of the cutting device grips. Such devices work satisfactorily in cable assembly machines that have cross-transporting grippers.

Ein Verfahren der im Oberbegriff des Anspruchs 1 angegebenen Art sowie eine Vorrichtung der im Oberbegriff des Anspruchs 8 angegebenen Art sind aus der US-A-3,155,136 bekannt. Demnach ist eine Leitungsspeichervorrichtung vorgesehen, die sich quer zur Transportrichtung einer abzulängenden Leitung in einer gerade verlaufenden Ebene erstreckt, und es ist eine Antriebseinrichtung für die Leitungsspeichervorrichtung vorgesehen, mit welcher diese in der genannten Ebene linear hin und her bewegt wird. Diese Konstruktion erfordert einen relativ großen Raum für die Hin- und Her-Bewegung der Leitungsspeichervorrichtung. Zudem müssen relativ große Massen beschleunigt und verzögert werden, worunter die Schnelligkeit der Leitungsspeichervorrichtung leidet.A method of the type specified in the preamble of claim 1 and a device of the type specified in the preamble of claim 8 are known from US-A-3,155,136. Accordingly, a line storage device is provided which extends transversely to the transport direction of a line to be cut to length in a plane running straight, and a drive device is provided for the line storage device with which it is moved linearly back and forth in said plane. This construction requires a relatively large space for the reciprocating movement of the line storage device. In addition, relatively large masses must be accelerated and decelerated, which affects the speed of the line storage device.

Neuerlich sind aber Kabelkonfektionierautomaten entwickelt worden, deren Quertransportvorrichtung sehr viel schneller arbeitet als die mit Greifern bestückten Quertransportvorrichtungen herkömmlicher Konfektionierautomaten. Eine derartige schneller laufende Quertransportvorrichtung wird z. B. in der DE-OS 32 12 542 beschrieben. Diese bekannte Quertransportvorrichtung weist eine erste Fördervorrichtung auf, die die von der Kabeltrommel gewickelte Leitung in Richtung ihrer Längsachse zur Ablängstation transportiert. Sie verfügt zudem über eine sich anschließende zweite Fördervorrichtung, die im wesentlichen von zwei parallel nebeneinander angeordneten Endlosriemen gebildet wird, die die abgelängte Leitung zwischen sich einklemmend senkrecht zur Leitungslängsachse zu den Bearbeitungsstationen weitertransportieren. Für die Übergabe der Leitung aus der ersten Fördervorrichtung an die zweite Fördervorrichtung ist ein Kanal vorgesehen, der sich an die erste Fördervorrichtung anschließt, in den die Leitung in seiner Längsachse gefördert wird und der sich bis zur zweiten Fördervorrichtung erstreckt. Von der der zweiten Fördervorrichtung abgewandten Seite her greift ein Schieber in den Kanal, der die im Kanal befindliche Leitung durch einen gegenüberliegenden, sich beim Vorschub des Schiebers öffnenden Schlitz zwischen die Riemen des zweiten Förderers schiebt und dabei mit einer entsprechenden Trennmesseranordnung ablängt. Um zu verhindern, daß das abgeschnittene, in der Ablängvorrichtung verbleibende vordere Leitungsende des nächsten Leitungsstückes deformiert wird, wird das Leitungsende, das beim Ablängen verschwenkt wird, in einer mitschwenkenden Hülse geführt, die das Leitungsende nach dem Ablängen wieder zurückschwenkt und so positioniert, daß es störungsfrei in den Kanal eingefädelt werden kann.Recently, however, automatic cable assembly machines have been developed whose transverse transport device works much faster than the transverse transport devices equipped with grippers of conventional automatic assembly machines. Such a faster-running cross transport device is used, for. B. described in DE-OS 32 12 542. This known transverse transport device has a first conveyor device which transports the line wound by the cable drum in the direction of its longitudinal axis to the cutting station. It also has an adjoining second conveying device, which is essentially formed by two endless belts arranged parallel to one another, which, by being clamped, transport the cut line between them perpendicular to the longitudinal axis of the line to the processing stations. For the transfer of the line from the first conveying device to the second conveying device, a channel is provided which connects to the first conveying device, into which the line is conveyed in its longitudinal axis and which extends to the second conveying device. From the side facing away from the second conveying device, a slide engages in the channel, which pushes the line in the channel through an opposite slot that opens when the slide is advanced between the belts of the second conveyor and thereby cut to a corresponding cutting knife arrangement. In order to prevent the cut, in the cutting device remaining front line end of the next line section from being deformed, the line end, which is pivoted during cutting, is guided in a pivoting sleeve which pivots the line end back after cutting and positions it so that it can be threaded into the channel without interference.

Für diesen neuen Typ von Kabelkonfektionierautomaten arbeiten die bekannten Leitungswechsler zu langsam. Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung für einen solchen Kabelkonfektionierautomaten zu schaffen, mit denen Leitungen sehr schnell gewechselt bzw. positioniert werden können, wobei die Vorrichtung insbesondere auch eine hohe Speicherkapazität verschiedener Leitungen haben soll.The known cable changers work too slowly for this new type of automatic cable assembler. It is therefore an object of the present invention to provide a method and a device for such an automatic cable assembly machine, with which lines can be changed or positioned very quickly, the device in particular also having a high storage capacity for different lines.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und des Anspruchs 8 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den davon abhängigen Unteransprüchen gekennzeichnet. Anhand des in der Zeichnung abgebildeten Beispieles eines Leitungswechslers wird die Erfindung im folgenden näher erläutert. Es zeigen:

This object is achieved by the features of claims 1 and 8. Advantageous developments of the invention are characterized in the dependent claims. Based on the example of a line changer shown in the drawing, the invention is explained in more detail below. Show it:

Der Leitungswechsler weist im wesentlichen eine verschwenkbare Speichervorrichtung 1 und eine Transportvorrichtung 2 sowie eine nachgeordnete Ablängvorrichtung 3 auf.The line changer essentially has a pivotable storage device 1 and a transport device 2 as well as a downstream cutting device 3.

Die verschwenkbare Speichervorrichtung 1 besteht aus mindestens zwei gleichen, in Transportrichtung 4 der Leitung 5 hintereinander im Abstand einen Zwischenraum 20 bildend angeordneten, konvexbogenförmig nach oben ragenden Balken 6 und 7, in die jeweils eine Lochreihe 8,9 eingebracht ist mit sich in Transportrichtung 4 erstreckenden, jeweils auf einem Kreisbogen auf seitlichem Abstand voneinander angeordneten durchgehenden Löchern 10, wobei die Löcher 10 der Lochreihe 9 mit den Löchern 10 der Lochreihe 8 fluchten und alle Löcher 10 vorzugsweise einen gleichen Durchmesser aufweisen, so daß die Leitungen (5) längs einer geraden Mantellinie einer kreisbogenförmig gekrümmten Fläche gelagert sind. An den freien Enden der Balken 6 und 7 ist jeweils ein Stützarm 11 angeordnet, wobei die Stützarme 11 eines Balkens 6 oder 7 V-förmig nach unten aufeinanderzulaufend ausgerichtet sind und in einen nach unten ragenden Schwenkarm 12 übergehen. Im freien unteren Endbereich stehen die Schwenkarme 12 über eine horizontal angeordnete, in den Endbereichen drehbar gelagerte Schwenkachse 13 miteinander in Verbindung. Im Abstand senkrecht über der Schwenkachse 13 steckt in jedem Schwenkarm 12 eine sich parallel zur Schwenkachse 13 erstreckende kurze Lagerachse 14, die jeweils in ein fest ruhendes Lagerfundament 15 greift und dort drehbar gelagert ist.The pivotable storage device 1 consists of at least two of the same, in the transport direction 4 Line 5 arranged one behind the other at a distance to form a space 20, beams 6 and 7 projecting upwards in the form of a convex arc, into each of which a row of holes 8, 9 is introduced, with through holes 10 extending in the transport direction 4 and each being arranged on a circular arc at a lateral distance from one another, wherein the holes 10 of the row of holes 9 are aligned with the holes 10 of the row of holes 8 and all the holes 10 preferably have the same diameter, so that the lines (5) are mounted along a straight surface line of an arcuate surface. A support arm 11 is arranged at the free ends of the beams 6 and 7, the support arms 11 of a beam 6 or 7 being aligned in a V-shape toward one another and passing into a swivel arm 12 projecting downwards. In the free lower end region, the swivel arms 12 are connected to one another via a horizontally arranged swivel axis 13 which is rotatably mounted in the end regions. At a distance vertically above the swivel axis 13, a short bearing axis 14, which extends parallel to the swivel axis 13, is inserted in each swivel arm 12, each of which engages in a fixed bearing foundation 15 and is rotatably mounted there.

Die Schwenkachse 13 durchgreift drehbar einen Block 16, der mit einer Kupplung 17 verbunden ist, an die ein Antriebsmittel (nicht dargestellt) angreift, das eine Bewegung in Doppelpfeilrichtung 18 erzeugt , so daß auf die Speichervorrichtung 1 eine Schwenkbewegung in Doppelpfeilrichtung 19 um die Lagerachsen 14 übertragen wird.The pivot axis 13 rotatably passes through a block 16 which is connected to a coupling 17 to which a drive means (not shown) engages which generates a movement in the double arrow direction 18, so that the storage device 1 pivots in the double arrow direction 19 about the bearing axes 14 is transmitted.

Nach einer besonderen Ausführungsform der Erfindung ist dem Balken 6 mit Abstand einen Zwischenraum bildend ein weiterer gleich gestalteter Balken 21 ebenfalls mit durchgehenden Löchern 10 auf einem Kreisbogen in einer Lochreihe 22 vorgeordnet, indem sich je ein parallel zur Transportrichtung 4 erstreckender Steg 24 an den beiden Stützarmen 11 an jeweils der gleichen Stelle angeordnet ist, von dem am freien Ende ein kurzer Stützarm 25 rechtwinklig nach oben abgeht, der am freien Ende des konvexbogenförmig geformten Balkens 21 sitzt.According to a special embodiment of the invention, the bar 6 forms a gap at a distance a further identically designed beam 21 also arranged with through holes 10 on a circular arc in a row of holes 22, each by a web 24 extending parallel to the transport direction 4 is arranged on the two support arms 11 at the same place, one at the free end short support arm 25 goes up at right angles, which sits at the free end of the convex-arc-shaped beam 21.

Durch die Löcher 10 sind Leitungen verschiedenen Typs gezogen, von denen nur eine Leitung 5 abgebildet ist, die von der nicht dargestellten Ablängeinrichtung eines ebenfalls nicht dargestellten Kabelkonfektionierautomaten gehandhabt wird. Die Leitung 5 überragt den Balken 7 in Transportrichtung 4 nach vorne erheblich. Alle anderen nicht dargestellten Leitungen schließen mit dem jeweiligen Loch 10 des Balkens 7 ab, ragen also nicht heraus.Lines of different types are drawn through the holes 10, of which only one line 5 is shown, which is handled by the cutting device (not shown) of an automatic cable assembly machine (also not shown). The line 5 projects significantly beyond the beam 7 in the direction of transport 4. All other lines, not shown, terminate with the respective hole 10 of the beam 7, so do not protrude.

Die Balken 6 und 7 sind mit Klemmeinrichtungen für jedes Loch 10 ausgerüstet. Eine Klemmeinrichtung kann z. B. einen Bolzen 26 aufweisen, der im Balken 6 oder 7 lagert und von oben oder unten in ein Loch 10 ragt. Mit geeigneten Mitteln wird der Bolzen auf die jeweilige Leitung gedrückt, so daß sie geklemmt wird. Nach Aufhebung der Klemmung kann die Leitung frei durch die Löcher 10 gezogen werden. Die Mittel zur Durchführung und Steuerung der Bewegung der Bolzen 26 sind nicht abgebildet.The bars 6 and 7 are equipped with clamping devices for each hole 10. A clamping device can, for. B. have a bolt 26 which is supported in the beam 6 or 7 and protrudes from above or below into a hole 10. The bolt is pressed onto the respective line with suitable means so that it is clamped. After removing the clamp, the line can be pulled freely through the holes 10. The means for carrying out and controlling the movement of the bolts 26 are not shown.

Der Balken 21 weist keine Klemmeinrichtung auf. Vielmehr ist im bzw. über dem Zwischenraum 23 im Bereich der Kulmination der Kreisbogen eine Schlaufenbildungseinrichtung 27 angeordnet, die mit nicht gezeigten Antriebsmitteln in Doppelpfeilrichtung 28 auf und nieder gefahren werden kann und beim Niederfahren auf die im Balken 6 geklemmte, unter der Schlaufenbildungseinrichtung 27 befindliche Leitung drückt, sie unter Bildung einer Schlaufe im Zwischenraum 23 durch das Loch 10 des Balkens 21 zieht und dabei von der nicht abgebildeten Kabelrolle abspult. Nach der Bildung einer Schlaufe fährt die Schlaufenbildungseinrichtung 27 wieder nach oben. Die Schlaufenbildungseinrichtung 27 weist im abgebildeten Beispiel ein sich drehendes Rad 28 a auf, dessen Lauffläche 29 gekehlt ist und dessen Achse 30 horizontal und senkrecht zur Transportrichtung 4 der Leitung 5 angeordnet ist, und zwar an einer Tragplatte 31, an der ein Antriebskupplungselement 32 sitzt, das mit einem nicht dargestellten Antriebsmittel in Verbindung steht. Der Zweck der Schlaufenbildung wird weiter unten erläutert.The bar 21 has no clamping device. Rather, a loop-forming device 27 is arranged in or above the intermediate space 23 in the region of culmination of the circular arc, which can be moved up and down in the double arrow direction 28 with drive means, not shown, and when descending onto the clamped in the bar 6, below the loop-forming device 27 located line presses, pulls it to form a loop in the space 23 through the hole 10 of the beam 21 and thereby unwinds from the cable reel, not shown. After the formation of a loop, the loop formation device 27 moves up again. In the example shown, the loop-forming device 27 has a rotating wheel 28 a, the running surface 29 of which is grooved and the axis 30 of which is arranged horizontally and perpendicularly to the transport direction 4 of the line 5, specifically on a support plate 31 on which a drive coupling element 32 is seated, which is connected to a drive means, not shown. The purpose of the loop formation is explained below.

Die Transportvorrichtung 2 ist im Zwischenraum 20 zwischen den Balken 6 und 7 angeordnet. Sie besteht im wesentlichen aus einem oberen endlosen, über Rollen 33 geführten Transportriemen 34, unter dem ein weiterer endloser, über Rollen 35 geführter Transportriemen 36 positioniert ist. Der untere Trum des Transportriemens 34 bildet mit dem oberen Trum des Transportriemens 36 einen Spalt 37. Die Transportriemen 34 und 36 sind in Transportrichtung 4 ausgerichtet, wobei sich der Spalt 37 in der Ebene der jeweils abzulängenden Leitung 5 befindet. Die Dicke des Spaltes 37 ist variierbar und entspricht während des Transportes einer Leitung 5 der Dicke dieser Leitung.The transport device 2 is arranged in the space 20 between the bars 6 and 7. It essentially consists of an upper endless conveyor belt 34 guided over rollers 33, under which another endless conveyor belt 36 guided over rollers 35 is positioned. The lower run of the transport belt 34 forms a gap 37 with the upper run of the transport belt 36. The transport belts 34 and 36 are aligned in the transport direction 4, the gap 37 being in the plane of the line 5 to be cut to length. The thickness of the gap 37 can be varied and corresponds to the thickness of this line during the transport of a line 5.

Nach der Erfindung ist sowohl der obere Transportriemen 34 als auch der untere Transportriemen 36 mit gleicher Geschwindigkeit antreibbar ausgeführt. Zum Beispiel treibt ein Motor 38 über einen Zahnriemen 39 ein auf der Achse 40 einer Rolle 33 sitzendes Zahnrad 41 an, wobei die Achsen 40 der Rollen 33 drehbar in einer senkrecht stehenden, seitlich der Rollen 33 angeordneten Lagerplatte 42 stecken. Die Kombination aus Zahnriementrieb mit Motor und Lagerplatte 42 mit oberer Transportriemenanordnung 33,34 ist um die in einer Fundamentplatte 42 a horizontal gelagerten Achse 38 a pendelnd gelagert, so daß eine gleichmäßige Flächenpressung auf der gesamten Länge der Zahnriemen bewirkt werden kann und Dickenschwankungen der Leitungen ausgeglichen werden können. Mit einem auf einer der Achsen 40 sitzenden weiteren Zahnrad (nicht dargestellt), das in ein nicht dargestelltes, auf einer der Achsen der Rollen 35 sitzendes Zahnrad eingreift, wird in an sich bekannter Weise der Antrieb auf den unteren Transportriemen 37 übertragen.According to the invention, both the upper transport belt 34 and the lower transport belt 36 can be driven at the same speed. For example, a motor 38 drives a toothed wheel 41 seated on the axle 40 of a roller 33 via a toothed belt 39, wherein the axes 40 of the rollers 33 are rotatably inserted in a vertical bearing plate 42 arranged laterally of the rollers 33. The combination of toothed belt drive with motor and bearing plate 42 with upper conveyor belt arrangement 33, 34 is oscillating about the axis 38 a, which is horizontally mounted in a foundation plate 42 a, so that a uniform surface pressure can be achieved over the entire length of the toothed belt and compensates for fluctuations in the thickness of the lines can be. With a further gearwheel (not shown) seated on one of the axes 40, which meshes with a gearwheel (not shown) seated on one of the axes of the rollers 35, the drive is transferred to the lower transport belt 37 in a manner known per se.

Nach einem weiteren Merkmal der Erfindung lagern die Rollen 35 des unteren Transportriemens 36 an einer von der Lagerung der Rollen 33 des oberen Transportriemens 34 unabhängigen Lagereinrichtung, die mit einer Hubeinrichtung 43 in Verbindung steht und in Doppelpfeilrichtung 46 auf-und abfahrbar ist. Diese Hubeinrichtung 46 kann aus zwei senkrecht stehenden Säulen 44 bestehen, die im Abstand voneinander und parallel im Abstand vom Transportriemen 36 angeordnet sind und jeweils in einem der Lagerfundamente 15 stecken. Die Säulen 44 durchgreifen jeweils eine Leitführungsbuchse 45, die über eine Verbindungsplatte 47 unter Bildung eines Hubschlittens 51 miteinander in Verbindung stehen. In der Verbindungsplatte 47 ist ein Loch 48 eingebracht, in dem eine um eine horizontale Achse 49 angetriebene Exzenterscheibe 50 sitzt. Der Antrieb ist nicht dargestellt. Das Loch 48 und die Exzenterscheibe 50 sind raumformmäßig so aufeinander abgestimmt, daß eine Drehbewegung der Exzenterscheibe 50 eine Auf- und Abbewegung des Hubschlittens 51 bewirkt. Von jeder Führungsbuchse 45 erstreckt sich oben und unten parallel zueinander verlaufend je ein Lagerarm 52 in Richtung des Transportriemens 36. Im freien Endbereich jedes unteren Lagerarms 52 steckt eine senkrecht stehende Säule 53, über die teleskopartig eine Hülse 54 formschlüssig gestülpt ist, die am unteren Ende einen ringförmigen Kragen 55 aufweist. Zwischen dem Kragen 55 und dem unteren Lagerarm 52 befindet sich auf der Säule 53 eine Spiraldruckfeder 53 a derart, daß die Hülse 54 in Doppelpfeilrichtung 56 bewegt werden kann. Jede Hülse 54 durchgreift formschlüssig frei ein Loch 57 im oberen Lagerarm 52, wobei am oberen freien Ende jeder Hülse die Achse einer Rolle 35 gelagert ist (nicht dargestellt).According to a further feature of the invention, the rollers 35 of the lower transport belt 36 are supported on a bearing device which is independent of the mounting of the rollers 33 of the upper transport belt 34 and is connected to a lifting device 43 and can be moved up and down in the double arrow direction 46. This lifting device 46 can consist of two vertically standing columns 44 which are arranged at a distance from one another and parallel at a distance from the transport belt 36 and are each inserted in one of the bearing foundations 15. The columns 44 each pass through a guide bushing 45, which are connected to one another via a connecting plate 47 to form a lifting slide 51. A hole 48 is made in the connecting plate 47, in which an eccentric disc 50 driven about a horizontal axis 49 is seated. The drive is not shown. The hole 48 and the eccentric disk 50 are coordinated in terms of space so that a rotary movement of the eccentric disk 50 causes the lifting carriage 51 to move up and down. A bearing arm 52 extends in the direction of the transport belt 36 from each guide bush 45, running parallel to one another at the top and bottom. The free end region of each lower bearing arm 52 is inserted a vertical column 53, over which a sleeve 54 is placed telescopically, which has an annular collar 55 at the lower end. Between the collar 55 and the lower bearing arm 52 there is a spiral compression spring 53 a on the column 53 such that the sleeve 54 can be moved in the double arrow direction 56. Each sleeve 54 freely engages through a hole 57 in the upper bearing arm 52, the axis of a roller 35 being mounted at the upper free end of each sleeve (not shown).

Wird der Hubschlitten 51 nach unten gefahren, nimmt er die Hülsen 54 und damit die Rollen 35 bzw. den Riemen 36 mit, und der Spalt 37 zwischen den Riemen 34 und 36 öffnet sich. Wird der Hubschlitten 51 nach oben gefahren, schließt sich der Spalt 37, bis der obere Trum des Transportriemens 36 von unten gegen die zu transportierende Leitung 5 drückt. Die federnde Lagerung der Hülsen 54 sorgt für einen gleichbleibenden Anpreßdruck zwischen den Riemen 34 und 36 gegen die Leitung 5 und einen Dickenausgleich bei unterschiedlich dicken Leitungen und Dickenschwankungen einer Leitung.If the lifting slide 51 is moved downward, it takes the sleeves 54 and thus the rollers 35 or the belt 36 with it, and the gap 37 between the belts 34 and 36 opens. If the lifting slide 51 is moved upwards, the gap 37 closes until the upper run of the transport belt 36 presses against the line 5 to be transported from below. The resilient mounting of the sleeves 54 ensures a constant contact pressure between the belts 34 and 36 against the line 5 and a thickness compensation for lines of different thicknesses and fluctuations in the thickness of a line.

Zum Wechseln einer Leitung 5 wird der Riemen 36 von der Hubeinrichtung 43 nach unten gezogen und die vorher zur Ablängung gezogene Leitung mit der Klemmeinrichtung in den Balken 6 und 7 geklemmt. Dann wird die Speichervorrichtung verschwenkt, bis die nächste abzulängende Leitung 5 in den geöffneten Spalt 37 gelangt ist. Dann wird der Spalt 37 wieder geschlossen und die Klemmeinrichtungen für diese Leitung geöffnet. Bei der Schwenkbewegung gewährleisten die gebildeten Schlaufen eine Pufferlänge, die aufgebraucht werden kann, indem die Leitungen aus den Löchern 10 des Balkens 21 entgegen der Transportrichtung 4 zurückgleiten können, wenn eine Zugkraft zwischen der Kabeltrommel und der geklemmten Leitung auftritt.To change a line 5, the belt 36 is pulled down by the lifting device 43 and the line previously drawn to length is clamped in the bars 6 and 7 with the clamping device. Then the storage device is pivoted until the next line 5 to be cut has reached the open gap 37. Then the gap 37 is closed again and the clamping devices for this line are opened. During the swiveling movement, the loops formed ensure a buffer length which can be used up by the lines being able to slide back out of the holes 10 of the bar 21 counter to the transport direction 4 if a tensile force exists between the cable drum and the clamped line occurs.

Der erfindungsgemäße Leitungswechsler arbeitet sehr schnell. Die gespeicherten Leitungen werden parallel zueinander angeordnet und lediglich auf einem Kreisbogen quer zur Transportrichtung 4 verschwenkt. Es ist weder ein Zurückziehen einer Leitung noch eine andere Manipulation erforderlich. Die freien Leitungsenden befinden sich immer in der Position, in der die Leitung nach der Verschwenkung sofort und unmittelbar in den Kanal gefördert werden kann. Der Leitungswechsler ist aus relativ leichten Bauelementen aufgebaut, so daß keine bedeutenden Massen bewegt werden müssen beim Verschwenken des Leitungsspeichers.The line changer according to the invention works very quickly. The stored lines are arranged parallel to one another and only pivoted on a circular arc transversely to the transport direction 4. No line retraction or other manipulation is required. The free pipe ends are always in the position in which the pipe can be conveyed into the sewer immediately and immediately after pivoting. The line changer is constructed from relatively light components, so that no significant masses have to be moved when pivoting the line store.

Nach der Erfindung ist der senkrechte Abstand zwischen der Achse 13 und jeder Achse 14 geringer als der radiale Abstand jeder Achse 14 zum Kreisbogen der Löcher 10, wobei sich jede Achse 14 im Mittelpunkt des Kreises,von dem der Kreisbogen ein Stück darstellt, befindet. Der Abstand zwischen jeder Achse 14 und dem Kreisbogen liegt vorzugsweise zwischen dem Zweifachen und dem Dreifachen des Abstandes zwischen der Achse 13 und jeder Achse 14. Durch diese Raumform einer Schwingenanordnung, bestehend aus Balken 6, 7, 21, Stützarmen 11 und 12 sowie Achsen 13 und 14, sind nur kurze Wege in Richtung des Doppelpfeiles 18 erforderlich, um relativ große Wege beim Verschwenken der Leitungen im Kreisbogen zu erzeugen. Außerdem sind relativ geringe Massen zu beschleunigen und zu verzögern, und es wird relativ viel Raum eingespart gegenüber z. B. geradlinig die Leitungen verschiebenden Vorrichtungen.According to the invention, the vertical distance between the axis 13 and each axis 14 is less than the radial distance of each axis 14 to the circular arc of the holes 10, with each axis 14 being in the center of the circle, of which the circular arc is a piece. The distance between each axis 14 and the circular arc is preferably between twice and three times the distance between the axis 13 and each axis 14. This spatial shape of a rocker arrangement, consisting of beams 6, 7, 21, support arms 11 and 12 and axes 13 and 14, only short distances in the direction of the double arrow 18 are required in order to produce relatively large distances when pivoting the lines in the circular arc. In addition, relatively small masses are to be accelerated and decelerated, and a relatively large amount of space is saved compared to e.g. B. straight lines moving devices.

Nach einer besonderen Ausführungsform der Erfindung besteht die dem Leitungswechsler nachgeordnete Ablängvorrichtung 3 aus einer Schneideinrichtung 60 und einer Klemmeinrichtung 61, die derart zusammenwirken, daß das abzulängende Stück der Leitung 5 während des Schneidvorganges klemmend festgehalten wird, bis es von einer nicht dargestellten Transportvorrichtung einem Konfektionierautomaten oder einer anderen Bearbeitungsstation zugeführt wird.According to a particular embodiment of the invention, the cutting device 3 arranged downstream of the line changer consists of a cutting device 60 and a clamping device 61, which cooperate in such a way that the piece of line 5 to be cut is clamped during the cutting process until it is transferred from a transport device (not shown) to an automatic assembly machine or is fed to another processing station.

Der Antrieb der Schneideinrichtung 60 erfolgt durch eine ortsfest gelagerte Antriebswelle 62, die in Richtung des Pfeils 63 rotiert und deren Rotationsachse 62 a vorzugsweise parallel zur Längserstreckung der Leitung 5 verläuft. An der Welle 62 ist zur Schaffung eines Kurbeltriebes einendig ein Exzenterzapfen 64 angeordnet, der über einen Gelenkkopf 65 eine Pleuelstange 66 trägt, die wiederum über einen Gelenkkopf 67 mit einem Schwenkarm 68 verbunden ist. Der Schwenkarm 68 ist an einem Ende einer ortsfest gelagerten und parallel zur Antriebswelle 62 angeordneten Schwenkachse 69 in etwa radialer Anordnung befestigt. An ihrem anderen Ende trägt die Schwenkachse 69 einen weiteren Schwenkarm 71 in ebenfalls radialer Ausrichtung, wobei die beiden Schwenkarme 68 und 71 in axialer Richtung der Schwenkachse 69 gesehen etwa V-förmig zueinander angeordnet sind. Der Schwenkarm 71 ist über einen Gelenkkopf 72, eine Pleuelstange 73 und einen weiteren Gelenkkopf 74 mit einem Schieber 75 verbunden, der senkrecht zur Leitung 5 und in Richtung des Doppelpfeils 76 längsverschieblich in einer Führung 77 gelagert ist. Der Schieber 75 ist etwa in der Form eines langgestreckten Quaders ausgebildet, wobei der Gelenkkopf 74 der Pleuelstange 73 in einer an einem Ende des Schiebers 75 ausgebildeten gabelförmigen Aufnahme 78 schwenkbeweglich gelagert ist. Der Schieber 75 trägt an seinem, dem Gelenkkopf 74 gegenüberliegenden Ende ein Schneidmesser 81 mit einer V-förmigen Schneide 82, die mit den nicht dargestellten Gegenschneiden in den Bohrungen 10 des Balkens 7 zum Ablängen der Leitung 5 scherenartig zusammenwirkt.The cutting device 60 is driven by a fixedly mounted drive shaft 62, which rotates in the direction of the arrow 63 and whose axis of rotation 62 a preferably runs parallel to the longitudinal extension of the line 5. To create a crank mechanism, an eccentric pin 64 is arranged at one end of the shaft 62 and carries a connecting rod 66 via an articulated head 65, which in turn is connected to a swivel arm 68 via an articulated head 67. The swivel arm 68 is attached to an end of a fixedly mounted and arranged parallel to the drive shaft 62 swivel axis 69 in an approximately radial arrangement. At its other end, the pivot axis 69 carries a further pivot arm 71 in a likewise radial orientation, the two pivot arms 68 and 71 being arranged approximately in a V shape relative to one another when viewed in the axial direction of the pivot axis 69. The swivel arm 71 is connected via a joint head 72, a connecting rod 73 and a further joint head 74 to a slide 75 which is mounted in a guide 77 so as to be longitudinally displaceable perpendicular to the line 5 and in the direction of the double arrow 76. The slider 75 is approximately in the form of an elongated cuboid, the joint head 74 of the connecting rod 73 is pivotally mounted in a fork-shaped receptacle 78 formed at one end of the slide 75. The slider 75 carries at its end opposite the joint head 74 a cutting knife 81 with a V-shaped cutting edge 82 which cooperates with the counter-cutting edges, not shown, in the bores 10 of the beam 7 to cut the line 5 to length.

Der Schwenkarm 68 ist im dargestellten Ausführungsbeispiel länger als der Schwenkarm 71 ausgebildet, so daß die Bewegung der Pleuelstange 66 untersetzt über die Pleuelstange 73 auf den Schieber 75 übertragen wird. Eine Einstellbarkeit der beiden Grenzstellungen der Hin- und Herbewegung des Schiebers 75 und damit der exakten Schnittwirkung ist dadurch gewährleistet, daß die Länge der Pleuelstangen 66 und 73 aufgrund der aufgeschraubten Gelenkköpfe 65, 67 und 72, 74 variabel ist. Dabei ist es zweckmäßig, wenn die Pleuelstangen 66, 73 einendig ein Rechtsgewinde 83 und anderendig ein Linksgewinde 84 sowie für jeden Gelenkkopf 65, 67, 72, 74 eine Kontermutter 85 aufweisen.The swivel arm 68 is longer in the illustrated embodiment than the swivel arm 71, so that the movement of the connecting rod 66 is transmitted via the connecting rod 73 to the slide 75. An adjustability of the two limit positions of the back and forth movement of the slide 75 and thus the exact cutting action is ensured in that the length of the connecting rods 66 and 73 is variable due to the screwed-on rod ends 65, 67 and 72, 74. It is expedient if the connecting rods 66, 73 have a right-hand thread 83 at one end and a left-hand thread 84 at the other end and a lock nut 85 for each joint head 65, 67, 72, 74.

Der Antrieb der Klemmeinrichtung 61 erfolgt ebenfalls durch die Antriebswelle 62, die hierzu über einen Zahnriemen 90 mit einer ortsfest gelagerten Welle 91 verbunden ist, die oberhalb der Antriebswelle 62 in zu dieser paralleler Ausrichtung angeordnet ist und somit ebenfalls in Pfeilrichtung 63 rotiert. An ihrem dem Zahnriemen 90 gegenüberliegenden Ende trägt die Welle 91 zwei Kurven- bzw. Nockenscheiben 92,93, auf deren Umfang jeweils ein Schwenkarm 94, 95 tangential aufliegt. Dabei ist es zweckmäßig, wenn die Schwenkarme 94,95 an ihren Enden drehbare Rollen 96, 97 aufweisen, deren Achsen parallel zur Welle 91 verlaufen.The clamping device 61 is also driven by the drive shaft 62, which for this purpose is connected via a toothed belt 90 to a stationary shaft 91 which is arranged above the drive shaft 62 in an orientation parallel to this and thus also rotates in the direction of arrow 63. At its end opposite the toothed belt 90, the shaft 91 carries two cam or cam disks 92, 93, on the circumference of which a pivot arm 94, 95 lies tangentially. It is expedient if the swivel arms 94, 95 have at their ends rotatable rollers 96, 97, the axes of which run parallel to the shaft 91.

Die Schwenkarme 94, 95 tangieren die Kurvenscheiben 92, 93 auf diametral gegenüberliegenden Seiten. Beide Schwenkarme 94,95 gehen vorzugsweise einstückig in ein und denselben Schwenkkörper 98 über, der mittels einer ortsfesten und zu den Wellen 62 und 91 parallelen Schwenkachse 99 schwenkbar gelagert ist. Auf der den Schwenkarmen 94, 95 gegenüberliegenden Seite weist der etwa quaderförmige Schwenkkörper 98 einen Finger 101 auf, der an seinem Ende einen Zapfen oder vorzugsweise eine Rolle 102 mit zur Welle 91 paralleler Drehachse trägt. Mit dieser Rolle 102 steht der Finger 101 mit einem Klemmschieber 103 in Eingriff, der in einer zur Erstreckung der transportierten Leitung 5 senkrechten Ebene verschiebbar geführt ist. Hierzu sind an zwei gegenüberliegenden senkrechten Seiten des Schiebers 75 der Schneideinrichtung 60 zwei Führungsschienen 104 befestigt, beispielsweise angeschraubt, die sich senkrecht nach oben erstrecken und zwischen sich einen Spalt 105 zur Aufnahme des Klemmschiebers 103 bilden. Zur Aufnahme der Rolle 102 weist der Klemmschieber 103 eine rechteckförmige Ausnehmung 106 auf, die in Richtung des Fingers 101 randoffen ausgebildet ist. Der Klemmschieber 103 besteht aus einem Flachmaterial, dessen Dicke dem Spalt 105 zwischen den Führungsschienen 104 entspricht. Auf seiner der Ausnehmung 106 gegenüberliegenden Seite trägt der Klemmschieber 103 einen Klemmfinger 107, der um eine zur Leitung 5 parallele Achse 108 schwenkbar gelagert ist. Der Klemmfinger 107 ist derart schräg nach unten orientiert, daß sein Ende 109 oberhalb der abzulängenden Leitung 5 angeordnet ist. Dem Ende 109 gegenüberliegend weist der Klemmfinger 107 eine Verlängerung 111 auf. Zwischen dem Klemmschieber 103 und der Verlängerung 111 des Klemmfingers 107 ist eine Spiraldruckfeder 112 angeordnet.The swivel arms 94, 95 touch the cams 92, 93 on diametrically opposite sides. Both pivot arms 94, 95 preferably merge in one piece into one and the same pivot body 98, which is pivotably mounted by means of a fixed pivot axis 99 parallel to the shafts 62 and 91. On the side opposite the swivel arms 94, 95, the approximately cuboid swivel body 98 has a finger 101 which carries at its end a pin or preferably a roller 102 with an axis of rotation parallel to the shaft 91. With this roller 102, the finger 101 is in engagement with a clamping slide 103 which is displaceably guided in a plane perpendicular to the extent of the transported line 5. For this purpose, two guide rails 104 are fastened, for example screwed, to two opposite vertical sides of the slider 75 of the cutting device 60, which extend vertically upwards and form a gap 105 between them for receiving the clamping slider 103. To accommodate the roller 102, the clamping slide 103 has a rectangular recess 106 which is designed to be open in the direction of the finger 101. The clamping slide 103 consists of a flat material, the thickness of which corresponds to the gap 105 between the guide rails 104. On its side opposite the recess 106, the clamping slide 103 carries a clamping finger 107 which is pivotably mounted about an axis 108 parallel to the line 5. The clamping finger 107 is oriented obliquely downwards in such a way that its end 109 is arranged above the line 5 to be cut. The clamping finger 107 has an extension 111 opposite the end 109. A spiral compression spring 112 is arranged between the clamping slide 103 and the extension 111 of the clamping finger 107.

Die Ablängvorrichtung arbeitet in der folgenden Weise. Die abzulängende Leitung 5 wird von der Transportvorrichtung 2 durch ein Loch 10 des Balkens 7 hindurchgeführt und gelangt in den Bereich zwischen dem Schneidmesser 81 und dem nicht dargestellten Gegenmesser. Bevor die Leitung 5 jedoch abgeschnitten wird, wird sie durch den Klemmfinger 107, und zwar zwischen dem Ende 109 des Fingers 107 und dem hinter dem Messer 81 angeordneten Ende des Schiebers 75 klemmend gehalten. Danach erfolgt der Schnitt durch die Verschiebebewegung des Schiebers 75.The cutting device works in the following way. The line 5 to be cut to length is guided by the transport device 2 through a hole 10 in the beam 7 and reaches the area between the cutting knife 81 and the counter knife (not shown). Before the line 5 is cut off, however, it is held in a clamping manner by the clamping finger 107, namely between the end 109 of the finger 107 and the end of the slide 75 arranged behind the knife 81. Then the cut is made by the sliding movement of the slide 75.

Ausgehend von der in der Zeichnung dargestellten Stellung des oberen Totpunktes des Kurbeltriebes 62, 64 rotiert die Welle 62 in Pfeilrichtung 63. Hierdurch wird in den ersten 10 bis 15° der Drehbewegung noch keine nennenswerte Bewegung der Pleuelstange 66 erzeugt, so daß auch der Schieber 75 nur eine geringe Verschiebebewegung ausführt und die Leitung 5 noch nicht abgeschnitten wird. Während dieser ersten 10 bis 15° der Drehbewegung der Antriebswelle 62 werden jedoch die Kurvenscheiben 92,93 ebenfalls um diesen Winkel gedreht. Aufgrund der gewählten Form der Kurvenscheiben 92, 93 mit relativ steil ansteigenden Flanken erfolgt während der ersten 10 bis 15° der Drehung bereits eine Verschwenkung des Schwenkkörpers 98 durch den Schwenkarm 94, wodurch der Finger 101 über die Rolle 102 den Klemmschieber 103 nach unten verschiebt (siehe den Doppelpfeil 113). Hierdurch wird das Ende 109 des Klemmfingers 107 in Richtung des Schiebers 75 bewegt, wodurch die Leitung 5 klemmend gehalten wird. Durch die Schwenkbeweglichkeit des Klemmfingers 107 (siehe den Doppelpfeil 114) und die Anordnung der Spiraldruckfeder 112 erfolgt die klemmende Halterung stets mit einer vorbestimmten Vorspannung, wobei ein Anschlag 115 die Schwenkbewegung des Klemmfingers 107 in der in Fig. 2 dargestellten Ausgangsstellung begrenzt. Erst nachdem die Leitung in der beschriebenen Weise gehalten wird, erfolgt durch weitere Drehung der Antriebswelle 62 über die Pleuelstange 66 eine zunehmende Verschwenkung der Schwenkarme 68 und 71 sowie über die Pleuelstange 73 eine Verschiebung des Schiebers 75 zum Abschneiden der Leitung 5, wobei der Klemmschieber 103 bei der Verschiebebewegung des Schiebers 75 mitgenommen wird, was der Doppelpfeil 116 andeuten soll. Das abgeschnittene Leitungsstück wird so lange gehalten, bis es von einer nicht dargestellten Transporteinrichtung erfaßt und weitertransportiert wird. Dies wird ebenfalls durch die Form der Kurvenscheiben 92, 93 erreicht, wodurch nur in dem jeweils richtigen Moment durch eine Rückverschwenkung des Schwenkkörpers 98 über den Schwenkarm 95 der Klemmschieber 107 nach oben verschoben wird und dieser so die Leitung 5 freigibt.Starting from the position of the top dead center of the crank mechanism 62, 64 shown in the drawing, the shaft 62 rotates in the direction of the arrow 63. As a result, no appreciable movement of the connecting rod 66 is produced in the first 10 to 15 ° of the rotary movement, so that the slide 75 executes only a slight shifting movement and the line 5 is not yet cut off. During this first 10 to 15 ° of the rotary movement of the drive shaft 62, however, the cams 92, 93 are also rotated by this angle. Due to the selected shape of the cam plates 92, 93 with relatively steeply rising flanks, the swivel body 98 is already pivoted by the swivel arm 94 during the first 10 to 15 ° of rotation, as a result of which the finger 101 moves the clamp slide 103 downward via the roller 102 ( see double arrow 113). As a result, the end 109 of the clamping finger 107 is moved in the direction of the slide 75, as a result of which the line 5 is held in a clamping manner. Due to the pivoting mobility of the clamping finger 107 (see the double arrow 114) and the arrangement of the spiral compression spring 112, the clamping takes place Always with a predetermined bias, a stop 115 limits the pivoting movement of the clamping finger 107 in the starting position shown in Fig. 2. Only after the line is held in the manner described does further rotation of the swivel arms 68 and 71 take place by further rotation of the drive shaft 62 via the connecting rod 66, and a displacement of the slide 75 for cutting off the line 5 via the connecting rod 73, the clamping slide 103 is taken with the displacement movement of the slide 75, which is to indicate the double arrow 116. The cut line piece is held until it is gripped by a transport device, not shown, and transported further. This is also achieved by the shape of the cams 92, 93, as a result of which the clamping slide 107 is only displaced upward at the right moment by pivoting the swivel body 98 back via the swivel arm 95, thereby releasing the line 5.
