Description

Einrichtung für das fortlaufende Verschweißen von mitDevice for the continuous welding of with

einer thermoplastischen Hülle versehenen Einzelelementen Die Erfindung betrifft eine Einrichtung für das fortlaufende Verschweißen von mit einer thermoplastischen Hülle versehenen Einzelelementen in Form von elektrischen und/oder optischen Kabeln oder Leitungen, wobei die Einrichtung einen Erwärmungsteil und einen anschließenden Andruckteil enthält.Individual elements provided with a thermoplastic casing The invention relates to a device for the continuous welding of a thermoplastic Individual elements provided with sheaths in the form of electrical and / or optical cables or lines, the device having a heating part and a subsequent one Contains pressure part.

Beim Verschweißen von Einzelelementen ergeben sich im Rahmen der notwendigen Erwärmung der thermoplastischen Hüllen Schwierigkeiten insofern, als bei einer Berührung mit einer festen Auflagefläche ein zu großer mechanischer Abrieb des aufgeschmolzenen Kunststoffes eintreten kann. Außerdem ist bei einer Auflage der Einzelelemente auf einer dem Wärmeübergang dienenden z.B.When welding individual elements, the necessary Difficulties in heating the thermoplastic casings in that when they are touched with a solid contact surface too great mechanical abrasion of the melted Plastic can occur. In addition, the individual elements are in a support one used for heat transfer e.g.

metallischen Unterlage vielfach keine größere Durchlaufgeschwindigkeit möglich, weil der Wärmeübergang zu schlecht ist.metallic base often no higher throughput speed possible because the heat transfer is too bad.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art so zu verbessern, daß bei geringem Abrieb hohe Durchlaufgeschwindigkeiten erreicht werden können. Gemäß der Erfindung wird dies dadurch erreicht, daß im Erwärmungsteil eine zwischen den Einzelelementen angeordnete innere Fuhrungseinrichtung vorgesehen ist, die in Längsrichtung der Einzelelemente gesehen eine Folge von Austrittsdüsen für ein der Erwärmung dienendes gasförmiges Medium aufweist.The present invention is based on the object of a device of the type mentioned so that high throughput speeds with low abrasion can be achieved. According to the invention this is achieved in that in the heating part an inner guide device arranged between the individual elements is provided is, seen in the longitudinal direction of the individual elements, a sequence of outlet nozzles for a gaseous medium serving for heating.

Bei der erfindungsgemäßen Ausführung wird die zu schweißende Flanke der Hülle des jeweiligen Einzelelementes durch ein entsprechendes Medium, z.B. Heißluft aufgeschmolzen. Da hierbei das Einzelelement zumindest teilweise auf dem Gasstrom gleitet, wird der Abrieb verringert. Da zudem die Anzahl der aufeinanderfolgenden Düsen so groß gemacht werden kann, wie es die notwendige Temperaturerhöhung erfordert (ohne daß dabei zugleich eine entsprechende Vergrößerung des Reibungswiderstandes eintritt), kann die gewünschte Temperaturerhöhung in einfacher Weise erreicht werden, ohne daß dabei sonstige Nachteile in Kauf genommen werden müssen.In the embodiment according to the invention, the flank to be welded is the shell of the respective individual element by an appropriate medium, e.g. hot air melted. Since here the individual element is at least partially on the gas flow slides, the abrasion is reduced. Since also the number of consecutive Nozzles can be made as large as the necessary temperature increase requires (without at the same time a corresponding increase in the frictional resistance occurs), the desired temperature increase can be achieved in a simple manner, without any other disadvantages having to be accepted.

Wenn an den der Düse abgewandten Seiten des Einzelelementes trotzdem eine Berührung z.B. mit einer äußeren Führungseinrichtung erfolgt, so ist dies weniger kritisch, weil hier die Hülle nicht erwärmt ist und somit wesentlich besser gleitet. Dabei tritt also kaum ein Abrieb auf.If on the sides of the individual element facing away from the nozzle anyway if there is contact e.g. with an external guide device, this is less critical because the cover is not heated here and therefore slides much better. So there is hardly any abrasion.

Die Länge der jeweiligen Düsenreihe kann so gewählt werden, daß die notwendigen Schmelztemperaturen mit Sicherheit erreicht werden. Bei einer vergrößerten Länge der Düsenreihe ist bei sonst gleichen Bedingungen (d.h. z.B. gleicher Temperatur, gleichen Druck des ausströmenden Mediums) eine höhere Abzugsgeschwindigkeit erreichbar.The length of the respective row of nozzles can be chosen so that the necessary melting temperatures can be achieved with certainty. With an enlarged The length of the row of nozzles is otherwise the same (i.e. the same temperature, same pressure of the outflowing medium) a higher withdrawal speed can be achieved.

Weiterbildungen der Erfindung sind in den Unteransprüchen wiedergegeben.Further developments of the invention are given in the subclaims.

Die Erfindung wird nachfolgend an Hand von Zeichnungen näher erläutert. Es zeigen Fig. 1 teilweise geschnitten den Aufbau einer erfindungsgemäßen Einrichtung und Fig. 2 einen Teilausschnitt der Anordnung nach Fig. 1, welche den Verlauf eines Einzelelementes im Bereich der Düsenreihen zeigt.The invention is explained in more detail below with reference to drawings. Show it Fig. 1 partially sectioned the structure of an inventive Device and FIG. 2 shows a partial section of the arrangement according to FIG. 1, which shows the Shows the course of an individual element in the area of the nozzle rows.

Bei der Anordnung nach Fig. 1 ist angenommen, daß als Einzelelemente zwei Kabel KA1 und KA2 miteinander verschweißt werden sollen. Diese Kabel kommen von einer hier nicht dargestellten Vorratsspule und werden über zwei Führungsringe FR1, FR2 einem Erwärmungsteil ET zugeführt. Dort werden die einander zugekehrten Oberflächenbereiche der thermoplastischen Hüllen der beiden Kabel KAI und KA2 soweit erwärmt, daß es zu einem Aufschmelzen kommt. In einem nachfolgenden Andruckteil AT werden mit Hilfe von vier federnd gelagerten und in ihrem Abstand verstellbaren Andruckrollen AN1 bis AN4 die geschmolzenen Teilbereiche der beiden Kabel KA1 und KA2 so zusammengedrückt, daß es im Bereich der Beriihrungsflache zu einer Verschmelzung kommt.In the arrangement of FIG. 1 it is assumed that as individual elements two cables KA1 and KA2 are to be welded together. These cables are coming from a supply reel, not shown here, and are via two guide rings FR1, FR2 fed to a heating part ET. There those facing each other will be Surface areas of the thermoplastic sheaths of the two cables KAI and KA2 so far heated that it comes to a melting. In a subsequent pressure part AT are with the help of four spring-loaded and adjustable in their distance Pressure rollers AN1 to AN4, the melted portions of the two cables KA1 and KA2 so compressed that it merges in the area of the contact area comes.

Im Erwärmungsteil ET sind eine aus zwei Teilen bestehende äußere Führungseinrichtung AF1, AF2 und eine innere Führungseinrichtung IF vorgesehen. Die äußere Führungseinrichtung AF1, AF2 hat von der Seite her gesehen etwa die Konfiguration eines Trapezes, dessen breiterer Teil im Bereich des Andruckteiles AT liegt. Im einzelnen sind hierzu auf einer größeren Tragplatte zwei Führungsplatten angebracht, die über Langlöcher LL1 bis LL4 verschiebbar und mittels entsprechender Halteschrauben feststellbar ausgebildet sind. Jedes Teil der äußeren Führungseinrichtung AFX, AF2 weist eine dem Kabel KA1 bzw. KA2 jeweils zugekehrte V-Nut LN auf, an welcher das jeweilige Kabel mit jeweils einer Mantellinie anliegt. Einzelheiten hierzu sind aus Fig. 2 ersichtlich.In the heating part ET are an outer guide device consisting of two parts AF1, AF2 and an inner guide device IF are provided. The outer guide device AF1, AF2 has roughly the configuration of a trapezoid when viewed from the side wider part lies in the area of the pressure part AT. In detail are on this two guide plates attached to a larger support plate, which are connected via elongated holes LL1 Designed to be slidable up to LL4 and lockable by means of appropriate retaining screws are. Each part of the outer guide device AFX, AF2 has a cable KA1 or KA2 each facing V-groove LN, on which the respective cable with each rests against a surface line. Details on this are can be seen from FIG.

Im Bereich der äußeren Führungseinrichtung AFI, AF2 ist zusätzlich eine Kühleinrichtung vorgesehen, welche einen Zuflußstutzen ZFI bzw. ZF2 und einen Rückflußstutzen RFI bzw. RF2 aufweist. Dies ist deshalb notwendig, damit es in demjenigen Bereich, in dem die durchlaufenden Einzelelemente in Form der Kabel KAI und KA2 an der Wandung der V-förmigen Nut LN anliegen, zu keiner größeren Temperaturerhöhung kommen kann und damit die thermoplastische Schutzhülle des jeweiligen Kabels dort nicht schmilzt und somit ein Abrieb vermieden wird.In the area of the outer guide device AFI, AF2 is also a cooling device is provided, which has an inflow connection ZFI or ZF2 and a Has reflux port RFI or RF2. This is therefore necessary in order for it to be in the person Area in which the continuous individual elements in the form of cables KAI and KA2 rest on the wall of the V-shaped groove LN, to no major increase in temperature can come and thus the thermoplastic protective sheath of the respective cable there does not melt and thus abrasion is avoided.

Parallel zu dem etwa keilförmigen Ausschnitt, welcher durch die beiden äußeren Führungsteile AFI und AF2 gebildet wird, ist eine keilförmig oder konisch verlaufende innere Führungseinrichtung IF vorgesehen. Im vorliegenden Beispiel hat diese die Form eines Hohlkegels, dessen durch einen dicken Strich angedeutete Wandung eine Reihe von Austrittsdüsen ADI bis ADn aufweist.Parallel to the roughly wedge-shaped cutout that goes through the two outer guide parts AFI and AF2 is formed, one is wedge-shaped or conical extending inner guide device IF provided. In this example, this the shape of a hollow cone, the wall indicated by a thick line has a number of outlet nozzles ADI to ADn.

Diese Düsen verlaufen mit ihren Öffnungen etwa in radialer Richtung bezogen auf die Längsachse der Kabel KAI und KA2, d.h. die austretende Heißluft trifft etwa senkrecht auf die äußere Hülle (Mantel) des jeweiligen Kabels KAI bzw. KA2 auf. In das innere Führungsteil IF ist eine Außenbuchse AB eingeschoben, wobei beide an der Überlappungsstelle durch hier nicht näher dargestellte Flansch- oder Klemmeinrichtungen luftdicht miteinander verbunden werden. In das innere des so gebildeten, einen zylindrischen Teil AB und einen konischen Teil IF aufweisenden Innenteils wird über einen Anschlußstutzen DL ein gasförmiges Medium z.B. Druckluft eingeiührt. Mittels eines elektrischen Anschlusses EA wird eine im Inneren befindliche, hier nicht näher dargestellte Heizeinrichtung betätigt, so daß in ent- sprechend fein einstellbarer Weise (z.B. mittels einer Einstellvorrichtung MM) die gewünschte Temperatur für die durchströmende Druckluft bereitgestellt werden kann.These nozzles run with their openings approximately in the radial direction in relation to the longitudinal axis of the cables KAI and KA2, i.e. the escaping hot air meets approximately perpendicular to the outer sheath (jacket) of the respective cable KAI resp. KA2 on. An outer bushing AB is inserted into the inner guide part IF, with both at the point of overlap by flange or flange not shown here Clamping devices are connected airtight to one another. Into the inside of the so formed, a cylindrical part AB and a conical part IF having A gaseous medium, e.g. compressed air, is supplied internally via a connection nozzle DL introduced. By means of an electrical connection EA, an inside, Heater not shown here actuated, so that in ent- speaking finely adjustable manner (e.g. by means of an adjusting device MM) the desired Temperature can be provided for the compressed air flowing through.

Im Betrieb strömt die über den Anschlußstutzen DL zugeführte Druckluft über die jeweilige Düsenrethe mit den Austrittsdüsen ADI bis ADn aus und trifft direkt auf die Hülle des davor liegenden Kabels, welche durch die ausströmende Luft erwärmt, angeschmolzen und gleichzeitig zumindest teilweise von der Mantelfläche der inneren Führungseinrichtung IF abgehoben wird. Die Länge der Düsenreihe mit den Austrittsdüsen AD1 bis ADn und die Temperatur der hindurchströmenden Heißluft sind so aufeinander abzustimmen, daß die gewünschte Schmelztemperatur am Ende, d.h. etwa im Bereich der Düse AD1 mit Sicherheit erreicht ist.During operation, the compressed air supplied via the connecting piece DL flows via the respective nozzle retainer with the outlet nozzles ADI to ADn and hits directly onto the sheath of the cable in front, which is penetrated by the air flowing out heated, melted and at the same time at least partially from the lateral surface the inner guide device IF is lifted off. The length of the row of nozzles with the outlet nozzles AD1 to ADn and the temperature of the hot air flowing through must be coordinated in such a way that the desired melting temperature at the end, i.e. approximately in the area of the nozzle AD1 is reached with certainty.

Das Kabel KA wird bezogen auf die innere Führungseinrichtung IF auf einer Art Luftpolster bewegt. Bei arollständigem Abheben kommt kein Materialkontakt zwischen der aus thermoplastischem Material bestehenden Hülle des Kabels KA1 und der Außenwandung der inneren Führungseinrichtung IF zustande. Auch bei nur teilweisem Abheben sind die Reibung und der~Abrieb bedeutend vermindert.The cable KA is based on the inner guide device IF a kind of air cushion moves. There is no material contact with complete lifting between the thermoplastic material sheath of the cable KA1 and the outer wall of the inner guide device IF. Even if only partially Lifting, the friction and abrasion are significantly reduced.

Die austretende Luft strömt, wie Fig. 2 zeigt, an den beiden Seiten über die dort gebildeten Längsschlitze LS aus. Da zudem das jeweilige Kabel z.B. KAI im Bereich des angrenzenden äußeren Führungsteils AF1 gekühlt wird, ist sichergestellt, daß nur der innenliegende Bereich des Umfanges des jeweiligen Kabels erwärmt und damit geschmolzen wird.The exiting air flows, as shown in FIG. 2, on both sides over the longitudinal slots LS formed there. Since the respective cable e.g. KAI is cooled in the area of the adjoining outer guide part AF1, it is ensured that that only the inner area of the circumference of the respective cable is heated and is melted with it.

Während die Justiermöglichkeit an den beiden äußeren Führungsteilen AFI und AF2 mittels der Langlöcher LL1 bis LL4 im wesentlichen nur der genauen und fluchtenden Ausrichtung dieser Teile dient, wird eine Anpassung an unterschiedliche Durchmesser der einlaufenden Kabel KA1 und KA2 zweckmäßig durch eine axiale Verschiebung der inneren Führungseinrichtung IF bewirkt.While the adjustment option on the two outer guide parts AFI and AF2 by means of the elongated holes LL1 to LL4 essentially only the exact and Alignment of these parts is used, an adaptation to different The diameter of the incoming cables KA1 and KA2 expediently by means of an axial displacement the inner guide device IF causes.

Hierzu ist die innere Führungseinrichtung IF auf einer hier nicht dargestellten Tragkonstruktion (Support o.For this purpose, the inner guide device IF is not on one here supporting structure shown (support or similar)

dgl.) verschiebbar und feststellbar gehalten.Like.) Slidably held and lockable.

Wenn mehr als zwei längslaufende Einzelelemente mit einander verschweißt werden sollen, dann kann entlang entsprechender Mantellinien der passend geformten Führungseinrichtung IF jeweils eine Düsenreihe angebracht werden.If more than two longitudinal individual elements are welded together are to be, then along the corresponding surface lines of the suitably shaped Guide device IF each have a row of nozzles attached.
