Description

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, mit einem Erwärmungstell, einem anschließenden Andruckteil und mit einer Führungseinrichtung, wobei das Erwärmungstell durch ein gasförmiges Medium erhitzbar und mit einer Folge von Austrittsdüsen versehen Ist.The invention relates to a device for the continuous Welding of individual elements provided with a thermoplastic shell in the form of electrical ones and / or optical cables or lines, with a heating position, a subsequent pressure part and with a guide device, wherein the heating position can be heated by a gaseous medium and is provided with a series of outlet nozzles.

Aus dem DE-GM 69 45 549 ist eine Vorrichtung zur Verschweißung zweier sich überlappender Folien bekannt, bei der zwischen den Folien eine etwa V-förmige Führungseinrichtung vorgesehen Ist. Diese Führungseinrichtung hat nur an ihrer Stirnseite eine rechteckige Düsenöffnung, so daß die aus Ihr austretende erwärmte Luft Im wesentlichen parallel zu den Folien und damit zur Durchlaufrichtung austritt. Die Erwärmung erfolgt hler nur In dem schmalen Zwickel kurz vor dem Zusammentreffen der beiden Folien. Eine ausreichende Erwärmung Ist damit nur bei sehr dünnen Folien und entsprechend niedrigen Durchlaufgeschwindigkeiten möglich.DE-GM 69 45 549 discloses a device for welding two overlapping foils known, in which an approximately V-shaped guide device is provided between the foils. These The guide device only has a rectangular nozzle opening on its front side, so that the nozzle opening out of it heated air emerges essentially parallel to the foils and thus to the direction of flow. The warming occurs only in the narrow gusset just before the two foils meet. A sufficient one This means that heating is only possible with very thin foils and correspondingly low throughput speeds possible.

Eine Einrichtung nach dem Oberbegriff des Anspruchs Ist aus der US-PS 32 25 278 bekannt. Dabei erfolgt die Erwärmung der Einzelelemente durch ein der Inneren (durch einen Stift gebildeten) Führungseinrichtung nachgeordnetes, mit nach oben gerichteten Austrittsdüsen für das strömende Medium versehenes Rohr. Diese Austrittsdüsen verlaufen im wesentlichen In tangentialer Richtung bezogen auf die Einzelelemente. Bei der bekannten Einrichtung werden durch die Austrittsdüsen in erster Linie nur die unteren Teile der Stirnselten zweier Folien erhitzt. Die Strömungsmöglichkeit für das erhitzte Medium wird im übrigen durch die jeweilige Breite der nach dem Stift vorhandenen, spitzwinklig zulaufenden Öffnung bestimmt.A device according to the preamble of the claim is known from US-PS 3,225,278. The Heating of the individual elements by a guide device downstream of the inner guide device (formed by a pin), pipe provided with upwardly directed outlet nozzles for the flowing medium. These Outlet nozzles run essentially in a tangential direction with respect to the individual elements. In the known device are through the outlet nozzles primarily only the lower parts of the forehead rarely two foils heated. The flow possibility for the heated medium is also determined by the respective Width of the acute-angled opening that is present after the pen is determined.

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 1st bei einer Auflage der Einzelelemente auf einer dem Wärmeübergang dienenden z. B. metallischen Unterlage vielfach keine größere Durchlaufgeschwindigkeit möglich, weil der Wärmeübergang zu schlecht ist.When individual elements are welded together, the thermoplastic elements need to be heated Enclosed difficulties in that when it comes into contact with a solid support surface, it is too large mechanical abrasion of the melted plastic can occur. In addition, the Individual elements on a heat transfer serving z. B. metallic base often no larger Throughput speed possible because the heat transfer is too poor.

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 die Führungseinrichtung zwischen den Einzelelementen angeordnet und als Erwärmungsteil ausgebildet 1st, und daß die dort angeordneten Austrittsdüsen auf jedes der Einzelelemente derart gerichtet sind, daß die Einzelelemente radial durch das gasförmige Medium anblasbar sind.The present invention is based on the object of providing a device of the type mentioned at the beginning to be improved so that high throughput speeds can be achieved with little abrasion. According to the invention this is achieved in that the guide device between the individual elements arranged and designed as a heating part 1st, and that the outlet nozzles arranged there on each of the Individual elements are directed such that the individual elements can be blown radially through the gaseous medium are.

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 Nachtelle in Kauf genommen werden müssen.In the embodiment according to the invention, the flank to be welded of the shell of the respective individual element is replaced by an appropriate medium, e.g. B. melted hot air. Since the individual element slides at least partially on the gas flow, the abrasion is reduced. Since the number of successive nozzles can also be made as large as the necessary temperature increase requires (without a corresponding increase in the frictional resistance occurring at the same time), the desired temperature increase can be achieved in a simple manner without any other disadvantages Need to become.

Wenn an den der Düse abgewandten Seiten des Einzelelementes trotzdem eine Berührung z. B. mit einer äußeren Führungseinrichtung erfolgt, so 1st dies weniger kritisch, well 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, a contact z. B. with an outer Guiding device takes place, so this is less critical, because here the shell is not heated and thus 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 with Security can be achieved. With an increased length of the row of nozzles, all other things being equal (i.e. z. B. same temperature, same pressure of the outflowing medium) a higher withdrawal speed accessible.

The outer guide device AF1, AF1 has approximately the configuration of a trapezoid, seen from the side, the wider part of which lies in the area of the pressure part AT. In detail, two guide plates are attached to a larger support plate for this purpose, which are designed to be displaceable via elongated holes up to LL 4 and lockable by means of corresponding retaining screws. Each part of the outer guide device AF1, AF1 has a V-groove LN facing the cable KAI or KAI , on which the respective cable rests with a surface line in each case. Details of this can be seen from FIG. 2.

Im Bereich der äußeren Führungseinrichtung AFl, AFl ist zusätzlich eine Kühleinrichtung vorgesehen, welche einen Zuflußstutzen ZFl bzw. ZFl und einen Rückflußstutzen RFl bzw. RFl aufweist. Dies ist deshalb notwendig, damit es in demjenigen Bereich, in dem die durchlaufenden Einzelelemente in Form der Kabel KAI und KAI an der Wandung der V-förmlgen 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 AF1, AF1 , a cooling device is additionally provided which has an inflow connection ZF1 or ZF1 and a return connection RF1 or RF1 . This is necessary so that in the area in which the continuous individual elements in the form of cables KAI and KAI rest on the wall of the V-shaped groove LN , there cannot be a major increase in temperature and thus the thermoplastic protective sheath of the respective cable cannot there melts and thus abrasion is avoided.

Parallel zu dem etwa keilförmigen Ausschnitt, welcher durch die beiden äußeren Führungsteile AFl und AFl 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 ADl bis ADn aufweist. Diese Düsen verlaufen mit Ihren Öffnungen etwa In radialer Richtung bezogen auf die Längsachse der Kabel KAI und KAI, d. h. die austretende Heißluft trifft etwa senkrecht auf die äußere Hülle (Mantel) des jeweiligen Kabels KAX bzw. KAI auf. In das innere Führungstell IF ist eine Außenbuchse AB eingeschoben, wobei beide an der Überlappungsstelle durch hler nicht näher dargestellte Flansch- oder Klemmeinrichtungen luftdicht miteinander verbunden werden. In das Innere des so gebildeten, einen zylindrischen Teil AB und einen konischen Tell IF aufweisenden Innenteils wlsd über einen Anschlußstutzen DL ein gasförmiges Medium z. B. Druckluft eingeführt. Mittels eines elektrischen Anschlusses EA wird eine im Inneren befindliche, hler nicht näher dargestellte Heizeinrichtung betätigt, so daß In entsprechend fein einstellbarer Weise (z. B. mittels einer Einstellvorrichtung MM) die gewünschte Temperatur für die durchsirömende Druckluft bereitgestellt werden kann.A wedge-shaped or conical inner guide device IF is provided parallel to the approximately wedge-shaped cutout which is formed by the two outer guide parts AF1 and AF1. In the present example, this has the shape of a hollow cone, the wall of which, indicated by a thick line, has a number of outlet nozzles AD1 to ADn . These nozzles run with their openings approximately in the radial direction with respect to the longitudinal axis of the cables KAI and KAI, ie the exiting hot air strikes the outer casing (jacket) of the respective cable KAX or KAI approximately perpendicularly. An outer bushing AB is pushed into the inner guide position IF , the two being connected to one another airtight at the point of overlap by flange or clamping devices not shown in detail. In the interior of the thus formed a cylindrical part and a conical AB Tell IF having inner part WLSD via a connection piece for a gaseous medium DL. B. compressed air introduced. By means of an electrical connection EA , a heating device located inside, not shown in detail, is actuated so that the desired temperature for the compressed air flowing through can be provided in a correspondingly finely adjustable manner (e.g. by means of an adjusting device MM).

Im Betrieb strömt die dJer den Anschlußstutzen DL zugeführte Druckluft über die jeweilige Düsenreihe mit den Austrittsdosen ADX 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 ADl 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 ADl mit Sicherheit erreicht ist.During operation, the compressed air supplied to the connecting piece DL flows out through the respective row of nozzles with the outlet sockets ADX to ADn and hits the sheath of the cable in front, which is heated by the air flowing out, melted and at the same time at least partially removed from the outer surface of the inner guide device IF is lifted. 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 so that the desired melting temperature is reached with certainty at the end, ie approximately in the area of the nozzle AD1.

Das Kabel KA wird bezogen auf die innere Führungseinrichtung IF auf einer Art Luftpolster bewegt. Bei vollständigem Abheben kommt kein Materialkontakt zwischen der aus thermoplastischem Material bestehenden Hülle des Kabels KAI und der Außenwandung der inneren Führungsreinrichtung IF zustande. Auch bei nur teilweisem Abheben sind die Reibung und der Abrieb bedeutend vermindert.The cable KA is moved on a type of air cushion in relation to the inner guide device IF. When it is completely lifted off, there is no material contact between the sheath of the cable KAI, which is made of thermoplastic material, and the outer wall of the inner guide device IF . Even with only partial lift-off, 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. fi KAI Im Bereich des angrenzenden äußeren Führungsteils AFl gekühlt wird, ist sichergestellt, daß nur der innenliegende Bereich des Umfanges des jeweiligen Kabels erwärmt und damit geschmolzen wird.As FIG. 2 shows, the exiting air flows out on both sides via the longitudinal slots LS formed there. Since the respective cable z. fi KAI is cooled in the area of the adjoining outer guide part AFl , it is ensured that only the inner area of the circumference of the respective cable is heated and thus melted.

Während die Justiermöglichkeit an den beiden äußeren Führungsteilen AFl und AFl mittels der Langlöcher LLl bis LLA Im wesentlichen nur der genauen und fluchtenden Ausrichtung dieser Teile dient, wird eine Anpassung an unterschiedliche Durchmesser der einlaufenden Kabel KAI und KAI zweckmäßig durch eine axiale Verschiebung der inneren Führungseinrichtung IF bewirkt. Hierzu 1st die Innere Führungseinrichtung IF auf einer hier nicht dargestellten Tragkonstruktion (Support od. dgl.) verschiebbar und feststellbar gehalten. While the adjustment option on the two outer guide parts AFl and AFl by means of the elongated holes LLl to LLA is essentially only used for the precise and aligned alignment of these parts, an adjustment to different diameters of the incoming cables KAI and KAI is expedient by axial displacement of the inner guide device IF causes. For this purpose, the inner guide device IF is held in a displaceable and lockable manner on a supporting structure (support or the like) not shown here.

Wenn mehr als zwei längslaufende Einzelelemente miteinander 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 to be welded together, a row of nozzles can be attached along corresponding surface lines of the suitably shaped guide device IF.
