Description

Die Erfindung betrifft eine Schweißheizung für das Herstellen von Kunststoffrohr­ matten, wobei die Kunststoffrohrmatten aus einer Anzahl parallel angeordneter flexi­ bler Kunststoffrohre bestehen, welche stoffschlüssig durch Schweißen mit einem Sammelrohr verbunden sind.The invention relates to a welding heater for the manufacture of plastic pipes mats, the plastic tube mats from a number of flexi arranged in parallel There are plastic pipes which are integrally welded with a Manifold are connected.

Eine derartige Schweißheizung ist aus der DE 17 04 261 A bekannt und dient für die Herstellung von Wärmetauschern aus Kunststoff, bei der ein Kunststoffrohrbündel mit zumindest einem Kunststoffrohrboden verschweißt wird.Such a welding heater is known from DE 17 04 261 A and is used for Manufacture of plastic heat exchangers using a plastic tube bundle at least one plastic tube sheet is welded.

Eine andere bekannte Schweißheizung (WO 92/09419 A1) sieht auf einer Grundplatte beidseitig parallel gegenüberliegende, mit Abstand angeordnete Schweißheizungen vor. In den Schweißspiegeln sind jeweils Heizkörper angeordnet. Jedoch bestehen die durch Schweißen zu verbindenden Körper aus thermoplastisch schmelzbaren Rohren gleichen Durchmessers. Beim Schweißen derartiger Kunststoffrohre, die mit ihrer Stirnfläche miteinander zu verbinden sind, besteht nicht das Problem, das beim Schweißen von Rohren unterschiedlicher Durchmesser, unterschiedlicher Wanddic­ ke, d. h. unterschiedlicher Masseanteile und völlig anderer Stoßrichtung auftritt. Der bekannte Gegenstand kann daher kein Vorbild für das Schweißen von im Durchmes­ ser/Wanddicke größeren Sammelrohren oder Verteilerrohren, auch Stammrohre genannt, mit sog. Kapillarrohren darstellen, aus denen Heiz- oder Kühlmatten gebil­ det werden. Es ist vielmehr bis heute nicht gelungen, derartige Kunststoffstammrohre mit Kapillarrohren derart dicht zu verschweißen, dass im Inneren der Durchflussquer­ schnitt des Kapillarrohrs nach dem Schweißen erhalten bleibt. Another known welding heater (WO 92/09419 A1) sees on a base plate Welding heaters located opposite each other in parallel on both sides and at a distance in front. Radiators are arranged in the welding mirrors. However exist the thermoplastic meltable bodies to be joined by welding Pipes of the same diameter. When welding such plastic pipes with to connect their end face to each other, there is no problem with the Welding pipes of different diameters, different wall thickness ke, d. H. different proportions of mass and completely different direction of impact occurs. The Known object can therefore not be a role model for welding in diameter water / wall thickness of larger collecting pipes or distribution pipes, also trunk pipes called, with so-called capillary tubes, from which heating or cooling mats gebil be det. Rather, it has not been possible to date to use such plastic trunk pipes welded so tightly with capillary tubes that inside the flow cross cut of the capillary tube is retained after welding.  

Zur Zeit werden Schweißheizungen eingesetzt, die aus einem Grundkörper beste­ hen. Dieser Grundkörper ist in einer Maschine angeordnet und wird durch Heizpatro­ nen auf die benötigte Temperatur gebracht. An diesem Grundkörper sind beidseitig Schweißspiegel angeordnet, die die spezielle Form für das Erwärmen der Kunst­ stoffteile besitzen. Es werden mit diesem Grundkörper auf der einen Seite Kunst­ stoffteile erwärmt, die eine kleine Masse besitzen, während auf der anderen Seite die Kunststoffteile eine große Masse besitzen.Welding heaters are currently being used which consist of the best of a basic body hen. This basic body is arranged in a machine and is made by Heizpatro brought to the required temperature. On this base body are on both sides Sweat mirrors arranged which are the special shape for heating the art own fabric parts. With this basic body, on the one hand, it becomes art heated parts of fabric that have a small mass, while on the other hand Plastic parts have a large mass.

Diese Ausführung der Schweißheizung hat den Nachteil, dass nur eine Temperatur zur Verfügung steht. Die flexiblen Kunststoffrohre haben aber einen ganz anderen Masseanteil wie das Sammelrohr. Die Wahl der Anheiztemperatur ist sehr schwierig und die Temperaturtoleranz muss klein gehalten werden, damit beim Anheizen die flexiblen Kunststoffrohre eine Temperatur einnehmen, die beim Verschweißen nicht zum Verbrennen der flexiblen Kunststoffrohre führt, und auch das Sammelrohr die benötigte Schweißtemperatur besitzt. Raumumgebungsbedingungen, wie Zugluft, Luftfeuchtigkeit und Raumtemperatur können sich schon nachteilig auf den Anheiz­ prozess auswirken. Es kann zu Verbrennungen bzw. zu nicht genügender Erwär­ mung der flexiblen Kunststoffrohre bzw. des Sammelrohrs kommen. In beiden Fällen wird ein ungenügendes Schweißergebnis erreicht.This version of the welding heater has the disadvantage that only one temperature is available. The flexible plastic tubes have a completely different one Mass share like the manifold. The choice of the heating temperature is very difficult and the temperature tolerance must be kept small so that when heating up the flexible plastic pipes reach a temperature that is not when welding leads to the burning of the flexible plastic pipes, and also the header pipe has the required welding temperature. Ambient conditions such as drafts, Air humidity and room temperature can adversely affect the heating impact process. It can cause burns or insufficient heating come the flexible plastic pipes or the manifold. In both cases an insufficient welding result is achieved.

Die Verbrennung des flexiblen Kunststoffrohrs kann man vermeiden, wenn man flexi­ bles Kunststoffrohr und Sammelrohr zeitlich unterschiedlich anheizt. Hierbei muss man allerdings mit Produktivitätsverlusten rechnen. Außerdem muss der Zeitunter­ schied neu eingeregelt werden, wenn man anderen Kunststoff mit einem anderen Temperaturverhalten einsetzt.The burning of the flexible plastic tube can be avoided if you flexi Bles plastic pipe and manifold heated differently in time. Here must however, productivity losses can be expected. In addition, the time must be re-adjusted if you use different plastic with another Temperature behavior begins.

Der Erfindung liegt die Aufgabe zugrunde, eine Schweißheizung für unterschiedliche Materialdicken auszuführen, bei der eine Verbrennung bzw. ungenügende Erwärmung der flexiblen Kunststoffrohre und des Sammelrohrs vermieden wird, die Raumumgebungsbedingungen keinen Einfluss auf das Anheizen haben und zeitlich keine Verluste bei der Herstellung von Kunststoffrohrmatten auftreten.The invention has for its object a welding heater for different Material thicknesses to be carried out in the event of a combustion or insufficient  Heating of the flexible plastic pipes and the collecting pipe is avoided Room ambient conditions have no influence on the heating and time no losses occur in the production of plastic pipe mats.

Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Patentanspruches 1 er­ findungsgemäß dadurch gelöst,
This object is achieved in connection with the preamble of claim 1 according to the invention by

  • - dass auf einer Grundplatte zwei Basiskörper gleicher oder unterschiedlicher Ausführung parallel und mit Abstand zueinander angeordnet sind,- That on a base plate two base bodies of the same or different Are arranged parallel and at a distance from each other,
  • - dass in der lösbaren Teilebene eines Basiskörpers ein oder mehrere Heize­ lemente längs zum Schweißspiegel angeordnet sind,- That one or more heaters in the detachable part level of a base body elements are arranged longitudinally to the welding mirror,
  • - und dass in dem anderen Basiskörper Heizelemente nacheinander im rech­ ten Winkel zum Schweißspiegel angeordnet sind.- And that in the other base body heating elements one after the other in arithmetic th angle to the welding mirror are arranged.

Vorteilhaft wurde gelöst, dass die Basiskörper symmetrisch ausgeführt sind.It was advantageously solved that the base bodies are designed symmetrically.

Die­ ses zusätzliche Heizelement kann zu- oder abschaltbar sein. Es kann hierdurch bei hohen Materialdicken eine bessere Energieanpassung vorgenommen werden.In the sub-plane of the first-mentioned base body, it is advantageous for the base body also contains another heating element in addition to the heating elements. the This additional heating element can be switched on or off. This can result in high material thicknesses a better energy adjustment can be made.

Die Basiskörper können aus Aluminium oder Invarstahl bestehen.The base body can be made of aluminum or invar steel.

Nach weiteren Merkmalen ist vorgesehen, dass die Grundplatte und die Basiskörper aus Invarstahl bestehen.According to further features, it is provided that the base plate and the base body consist of invar steel.

Zwischen den Basiskörpern kann vorteilhaft Isolationsmaterial angeordnet sein. Insulation material can advantageously be arranged between the base bodies.  

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die Gestaltung der Basiskörper und deren bedarfsgerechten Anordnung eine zielgerich­ tete Aufheizung der zu verschweißenden Teile vorgenommen werden kann. Außer­ dem sind schädliche Raumumgebungsbedingungen ausgeschlossen und es können kürzeste Fertigungszeiten ohne Schädigungen des Kunststoffes erzielt werden, wo­ bei Temperaturen und Aufheizzeiten von den zu verschweißenden Teilen spezifisch bestimmt werden können.The advantages achieved by the invention are in particular that Design of the basic body and its needs-based arrangement a targeted The parts to be welded can be heated. except harmful room conditions are excluded and it can shortest manufacturing times can be achieved without damaging the plastic where specific to the temperatures and heating times of the parts to be welded can be determined.

Auf einer Grundplatte 1 ist ein Isolationsmaterial 2 angeordnet, auf dem wiederum die beiden Basiskörper 3 und 4 parallel und mit Abstand angeordnet sind. Der Basis­ körper 3 ist mit einer lösbaren Teilebene 8 dargestellt. Die Teilebene 8 wird benötigt, damit Heizelemente 5 und 11, welche über die ganze Länge vom Basiskörper 3 rei­ chen, 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 Kunststoffs 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 Isolationsmaterial 2 bis in den Basiskörper 4 durchgeführt und im rechten Win­ kel zum Heizspiegel 10 hintereinander 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. An insulation material 2 is arranged on a base plate 1 , 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 sub-level 8 . The sub-level 8 is required so that heating elements 5 and 11 , which can 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 pre-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 holes in the base plate 1 and the insulation material 2 to the base body 4 and arranged in the right angle to the heating mirror 10 in a row. 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 ei­ ne axiale Verschiebung der Schweißspiegel 7, 10 möglich ist. Die Anpassung ist nö­ tig, wenn bei Wechsel der Kunststoffart die Verschweißtemperatur geändert werden muss und dadurch zwangsläufig andere Ausdehnungen der Basiskörper 3, 4 auftre­ ten.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 thermal expansion of the base body 3 , 4 ei ne axial displacement of the welding mirror 7 , 10 is possible. The adjustment is necessary if the welding temperature has to be changed when changing the type of plastic and this inevitably means that other dimensions of the base body 3 , 4 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 Alumi­ nium ausgeführt sind.So that the energy of the heating elements 5 , 9 and 11 can be quickly transported to the welding mirror 7 and 10 , it is useful if the base body 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 Ba­ siskörper 3, 4 aus Invarstahl auszubilden. Der Invarstahl besitzt einen Ausdehnungs­ koeffizienten, der nur 10% vom Wert des Ausdehnungskoeffizienten von Stahl ent­ spricht. Bei Temperaturänderungen treten dann nur vernachlässigbare Verschiebun­ gen 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 only corresponds to 10% of the value of the expansion coefficient of steel. With temperature changes then only negligible shifts 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 werden.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 bodies 3 , 4 are fixed in their relative positions to one another and are not displaced by the reaction forces during welding.

Zur Temperaturanpassung an die Schweißaufgabe besitzen die Basiskörper 3, 4 bei bestimmten Arbeitsaufgaben unterschiedliche Temperaturen. Es kann dabei von Vorteil sein, wenn Isolationsmaterial 2 zwischen beiden Basiskörpern 3, 4 angeord­ net wird, damit durch Strahlung die niedrige Temperatur eines Basiskörpers nicht verfälscht wird. In order to adapt the temperature to the welding task, the base bodies 3 , 4 have different temperatures for certain work tasks. It may be advantageous if insulation material 2 is arranged between the two base bodies 3 , 4 so that the low temperature of a base body is not falsified by radiation.
