Abstract

A welder heating system for production of plastic tube mats comprises parallel flexible plastic tubes welded to a collecting tube including two parallel basic bodies (3,4) located at a distance from each other on a base plate (1). One or more heating elements (5) are arranged in a parting plane (8) of the first basic body (3) along the length of the hot plate welding tool (7) and other heating elements (9) are located in the second basic body (4) at a right angle to a hot plate welding tool (10).

Description

Die Erfindung betrifft eine Schweißheizung für das Herstellen von Kunststoffrohrmatten, wo bei die Kunst­ stoffrohrmatten aus einer Anzahl parallel angeordneter flexibler Kunststoffrohre bestehen, welche stoffschlüs­ sig durch Schweißen mit einem Sammelrohr verbunden sind.The invention relates to a welding heater for the Manufacture of plastic pipe mats, where art tubular cloth mats from a number of arranged in parallel there are flexible plastic pipes, which are cohesive sig connected to a manifold by welding are.

Zur Zeit werden Schweißheizungen eingesetzt, die aus einem Grundkörper bestehen. Dieser Grundkörper 10 ist in einer Maschine angeordnet und wird durch Heiz­ patronen auf die benötigte Temperatur gebracht. An diesem Grundkörper sind beidseitig Schweißspiegel an­ geordnet, die die spezielle Form für das Erwärmen der Kunststoffteile besitzen. Es werden mit diesem Grund­ körper auf der einen Seite Kunststoffteile erwärmt, die eine kleine Masse besitzen, während auf der anderen Seite die Kunststoffteile eine große Masse besitzen.Welding heaters are currently used which consist of a basic body. This base body 10 is arranged in a machine and is brought to the required temperature by heating cartridges. Welding mirrors are arranged on both sides of this base body, which have the special shape for heating the plastic parts. With this basic body plastic parts are heated on one side, which have a small mass, while on the other side the plastic parts have a large mass.

Diese Ausführung der Schweißheizung hat den Nach­ teil, daß nur eine Temperatur zur Verfügung steht. Die flexiblen Kunststoffrohre haben aber einen ganz ande­ ren Masseanteil wie das Sammelrohr. Die Wahl der An­ heiztemperatur ist sehr schwierig und die Temperatur­ toleranz muß kleingehalten werden, damit beim Anhei­ zen die flexiblen Kunststoffrohre eine Temperatur ein­ nehmen, die zum Verschweißen nicht zum Verbrennen der flexiblen Kunststoffrohre führt, und auch das Sam­ melrohr die benötigte Schweißtemperatur besitzt. Raumumgebungsbedingungen, wie Zugluft. Luftfeuch­ tigkeit und Raumtemperatur können sich schon nach­ teilig auf den Anheizprozeß auswirken. Es kann zu Ver­ brennungen bzw. zu nicht genügender Erwärmung der flexiblen Kunststoffrohre bzw. des Sammelrohres kom­ men. In beiden Fällen wird ein ungenügendes Schweiß­ ergebnis erreicht.This version of the welding heater has the after partly that only one temperature is available. The flexible plastic pipes have a completely different one ren mass fraction like the manifold. The choice of the type heating temperature is very difficult and the temperature Tolerance must be kept low so that the flexible plastic pipes set a temperature take that for welding not for burning of the flexible plastic pipes, and also the Sam mel tube has the required welding temperature. Room environmental conditions, such as drafts. Humidity activity and room temperature can already change partly affect the heating process. It can lead to ver Burns or insufficient heating of the flexible plastic pipes or the manifold com men. In both cases there will be insufficient sweat result achieved.

Die Verbrennung des flexiblen Kunststoffrohres kann man vermeiden, wenn man flexibles Kunststoffrohr und Sammelrohr zeitlich unterschiedlich anheizt. Hierbei muß man allerdings mit Produktivitätsverlusten rech­ nen. Außerdem muß der Zeitunterschied neu eingere­ gelt werden, wenn man anderen Kunststoff mit einem anderen Temperaturverhalten einsetzt.The flexible plastic pipe can be burned you avoid if you have flexible plastic pipe and Collector pipe heated differently in time. Here one has to reckon with productivity losses nen. In addition, the time difference must be re-entered be valid if you use another plastic with a uses different temperature behavior.

Der Erfindung liegt die Aufgabe zugrunde, eine Schweißheizung für unterschiedliche Materialdicken auszuführen, bei der eine Verbrennung bzw. ungenü­ gende Erwärmung der flexiblen Kunststoffrohre und des Sammelrohres vermieden wird, die Raumumge­ bungsbedingungen keinen Einfluß auf das Anheizen ha­ ben, und zeitlich keine Verluste bei der Herstellung von Kunststoffrohrmatten auftreten.The invention has for its object a Welding heater for different material thicknesses to carry out a combustion or inaccurate sufficient heating of the flexible plastic pipes and the manifold is avoided, the space exercise conditions have no effect on heating ha ben, and no time losses in the production of Plastic pipe mats occur.

Die Aufgabe wird erfindungsgemäß dadurch gelöst.The object is achieved according to the invention.

  • - daß auf einer Grundplatte zwei Basiskörper glei­ cher oder unterschiedlicher Ausführung parallel und mit Abstand zu einander angeordnet sind,- That two base bodies are the same on a base plate cher or different execution parallel and are spaced from each other,
  • - daß in der lösbaren Teilebene eines Basiskörpers ein oder mehrere Heizelemente längs zum Heiz­ spiegel angeordnet sind, daß in einem anderen Ba­ siskörper die Heizelemente nacheinander im rech­ ten Winkel zum Heizspiegel angeordnet sind.- That in the detachable part of a base body one or more heating elements lengthways for heating mirrors are arranged that in another Ba siskkörper the heating elements one after the other in the right th angle to the heating mirror are arranged.

Vorteilhaft wurde gelöst, daß die Basiskörper symme­ trisch ausgeführt sind.It was advantageously solved that the base body symme are carried out trically.

In der Teilebene des erstgenannten Basiskörpers wird zu den vorhandenen Heizelementen ein zu- und ab­ schaltbares Heizelement angeordnet. Es kann hiermit bei hohen Materialdicken eine bessere Energieanpas­ sung vorgenommen werden. In the sub-level of the first-mentioned basic body to the existing heating elements on and off switchable heating element arranged. It can do this better energy adaptation at high material thicknesses solution.  

Die Basiskörper können aus Aluminium bzw. aus Invarstahl ausgebildet werden. Zwischen den Basiskörpern kann vorteilhaft Isolationsmaterial angeordnet sein.The base body can be made of aluminum or invar steel be formed. Between the basic bodies can advantageously arranged insulation material be.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch die Gestaltung der Basiskörper und deren bedarfsgerechten Anordnung eine zielgerichtete Aufheizung der zu verschweißenden Teile vorgenommen werden kann. Außerdem sind schädliche Raumumgebungsbedingungen ausgeschlossen und es können kürzeste Fertigungszeiten ohne Schädigungen des Kunststoffes erzielt werden, wobei Temperaturen und Aufheizzeiten von den zu verschweißenden Teilen spezifisch abgestimmt werden können.The advantages achieved with the invention are in particular in that by designing the base body and their needs-based arrangement is targeted The parts to be welded are heated can be. They are also harmful Room environment conditions excluded and it can have the shortest production times without damage of the plastic can be achieved, temperatures and heating times of the parts to be welded can be specifically tailored.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und im folgenden näher beschrieben. Die Zeichnung zeigt die schematische Darstellung der erfindungsgemäßen Schweißheizung, wobei ein Basiskörper mit Teilebene dargestellt ist und der andere Basiskörper keine Teilebene besitzt.An embodiment is shown in the drawing and described in more detail below. The drawing shows the schematic representation of the invention Welding heater, with a base body with Partial plane is shown and the other base body has no sub-level.

Auf der Grundplatte 1 ist der Isolierstoff 2 angeordnet, auf dem wiederum die beiden Basiskörper 3 und 4 parallel und mit Abstand angeordnet sind. Der Basiskörper 3 ist mit einer lösbaren Teilebene 8 dargestellt. Die Teilebene 8 wird benötigt, damit die Heizelemente 5 und 11, welche über die ganze Länge vom Basiskörper 3 reichen, angeordnet und bei Ausfall gewechselt werden können. Der Heizkörper 11 ist angeordnet, um bei großen Materialdicken zugeschaltet zu werden. Es steht somit die benötigte Energie zum Vorschweißen des Kunststoffes bei großen Materialdicken zur Verfügung. Der Basiskörper 4 ist, im Gegensatz zum Basiskörper 3, mit vielen Heizelementen 9 ausgestattet. Diese sind durch Bohrungen in der Basisplatte 1 und dem Isolierstoff 2 bis in den Basiskörper 4 durchgeführt und im rechten Winkel zum Heizspiegel 10 nacheinander angeordnet. Auch hier können, wie bei der vorhergehenden Lösung, einzelne Heizelemente 9 zum Vorschweißen von großen Kunststoffmaterialausbildungen geschaltet werden. Eine Schweißheizung kann mit zwei Basiskörpern 3, mit zwei Basiskörpern 4, oder mit je einem Basiskörper 3 und 4 ausgerüstet sein.On the base plate 1 , the insulating material 2 is arranged, on which in turn the two base bodies 3 and 4 are arranged in parallel and at a distance. The base body 3 is shown with a detachable partial plane 8 . The sub-level 8 is required so that the heating elements 5 and 11 , which extend over the entire length of the base body 3 , can be arranged and replaced in the event of failure. The heater 11 is arranged to be switched on with large material thicknesses. The energy required to weld the plastic with large material thicknesses is thus available. In contrast to the base body 3 , the base body 4 is equipped with many heating elements 9 . These are carried out through bores in the base plate 1 and the insulating material 2 into the base body 4 and successively arranged at right angles to the heating mirror 10 . Here too, as in the previous solution, individual heating elements 9 can be switched to pre-weld large plastic material constructions. A welding heater can be equipped with two base bodies 3 , with two base bodies 4 , or with one base body 3 and 4 each.

Die Basiskörper 3, 4 besitzen Flächen 6 zur Aufnahme der Schweißspiegel 7 und 10. Die Schweißspiegel 7 und 10 sind in ihrer Form an die Schweißaufgabe angepaßt. Die Fläche 6 ist so gestaltet, daß bei einer Wärmedehnung der Basiskörper 3, 4 eine axiale Verschiebung der Schweißspiegel 7, 10 möglich ist. Die Anpassung ist nötig, wenn bei Wechsel der Kunststoffart die Verschweißtemperatur geändert werden muß, und dadurch zwangsläufig andere Ausdehnungen der Basiskörper 3, 4 auftreten.The base bodies 3, 4 have surfaces 6 for receiving the welding mirrors 7 and 10 . The shape of the welding mirrors 7 and 10 is adapted to the welding task. The surface 6 is designed so that the thermal expansion of the base body 3, 4, an axial displacement of the welding mirror 7, 10 is possible. The adjustment is necessary if, when changing the type of plastic, the welding temperature has to be changed, and as a result other dimensions of the base body 3, 4 necessarily occur.

Damit die Energie der Heizelemente 5, 9 und 11 schnell an die Schweißspiegel 7 und 10 transportiert werden kann, ist es sinnvoll, wenn die Basiskörper 3, 4 in Aluminium ausgeführt sind.So that the energy of the heating elements 5, 9 and 11 can be quickly transported to the welding mirrors 7 and 10 , it is useful if the base bodies 3, 4 are made of aluminum.

Es kann allerdings auch sinnvoll sein, vor allem dann, wenn durch Materialwechsel die Temperaturen ständig angepaßt werden müssen, die Grundplatte 1 und die Basiskörper 3, 4 aus Invarstahl auszubilden. Der Invarstahl besitzt einen Ausdehnungskoeffizienten, der nur 10% vom Wert des Ausdehnungskoeffizienten von Stahl entspricht. Bei Temperaturänderungen treten dann nur noch vernachlässigbare Verschiebungen auf.However, it can also be useful, especially if the temperatures have to be constantly adjusted by changing the material, to form the base plate 1 and the base body 3, 4 from Invar steel. The Invar steel has an expansion coefficient that corresponds to only 10% of the value of the expansion coefficient of steel. With temperature changes, only negligible shifts then occur.

In der Zeichnung nicht dargestellt ist eine Lösung, bei der die beiden Basiskörper 3, 4 auf der Gegenseite der Grundplatte 1 miteinander verbunden sind. Diese Lösung hat den Vorteil, daß die Basiskörper 3, 4 in ihrer relativen Position zueinander fixiert sind, und durch die Reaktionskräfte beim Schweißen nicht verschoben wer­ den.A solution is not shown in the drawing, in which the two base bodies 3, 4 are connected to one another on the opposite side of the base plate 1 . This solution has the advantage that the base body 3, 4 are fixed in their relative position to each other, and not shifted by the reaction forces during welding who the.

Zur Temperaturanpassung an die Schweißaufgabe besitzen die Basiskörper 3, 4 bei bestimmten Arbeitsauf­ gaben unterschiedliche Temperaturen. Es kann dabei von Vorteil sein, wenn Isolationsmaterial zwischen bei­ den Basiskörpern 3, 4 angeordnet wird, damit durch Strahlung die niedrige Temperatur eines Basiskörpers nicht verfälscht wird.To adapt the temperature to the welding task, the base bodies 3 , 4 have different temperatures in certain work tasks. It can be advantageous here if insulation material is arranged between the base bodies 3 , 4 , so that the low temperature of a base body is not falsified by radiation.
