Description
Bezeichnung : "Einrichtung an einer Preßplatte,in deren Inne-Designation: "Device on a press plate, in the interior of which
ren Heizelemente eingebettet sind" Die Erfindung richtet sich auf eine Einrichtung an einer Preßplatte für eine Vorrichtung zum thermischen Verbinden von mindestens zwei Enden, insbesondere von Fördergurtenden, in deren Inneren Heizelemente eingebettet sind. ren heating elements are embedded " The invention is directed to a device on a press plate for a device for thermal Connect at least two ends, in particular conveyor belt ends, in their Inner heating elements are embedded.
Derartige Preßplatten sind z.B. durch das Patent 27 27 300 der Anmelderin bekannt. Wesentlich bei derartigen Preßplatten ist die möglichst genaue Temperatureinhaltung aller Flächen und Steuerung und Nachregelung ggf. unterschiedlich geheizter oder gekühlter Plattenbereiche.Such press plates are described, for example, by the applicant's patent 27 27 300 known. It is essential that the temperature is maintained as precisely as possible with such press plates of all surfaces and control and readjustment, if necessary, differently heated or cooled plate areas.
Eine derartige Überwachung, Regelung und Steuerung mit einfachen Mitteln ist Aufgabe der Erfindung.Such monitoring, regulation and control with simple means is the object of the invention.
Diese Aufgabe wird bei einer Einrichtung der eingangs bezeichneten Art gemäß der Erfindung dadurch gelöst, daß die Preßplatten in jeweils von einem elektrischen Widerstandselement beaufschlagte Zonen aufgeteilt und jede Zone einzeln thermisch überwacht ist.In the case of a facility, this task is described at the outset Kind according to the invention solved in that the press plates in each of one electrical resistance element applied zones divided and each zone individually is thermally monitored.
In Ausgestaltung sieht die Erfindung vor, daß bei einer Preßplatte mit drei Zonen die mittlere Zone jeder Preßplatte mit einem Widerstandstemperaturfühler und die beiden benachbarten äußeren Zonen mit mindestens einem Thermostat ausgerüstet sind.In an embodiment, the invention provides that with a press plate with three zones, the middle zone of each press plate with a resistance temperature sensor and the two adjacent outer zones are equipped with at least one thermostat are.
Durch die Erfindung ist mit einfachen Mitteln sowohl die optimale Regelung der Heizleistung als auch das Erfassen unterschiedlicher Tempraturverläufe innerhalb jeder Preßplatte erreichbar, so daß gewährleistet ist, daß ein zwischen den so ausgerüsteten Heizplatten liegender Fördergurt mit seinen Enden optimal vulkanisierbar ist. Bei dem bevorzugten Einsatzgebiet derartiger Vorrichtungen im rauhen Untertagebaubetrieb muß die Regelung und Steuerung möglichst einfach und robust sein, was durch die Erfindung erreicht wird.With the invention, both the optimal Control of the heating power as well as the recording of different temperature profiles reachable within each press plate, so that it is ensured that a between The ends of the conveyor belt lying on the heated platens can be optimally vulcanized is. In the preferred field of application of such devices in rough underground mining the regulation and control must be as simple and robust as possible, which is due to the Invention is achieved.
In weiterer Ausgestaltung ist nach der Erfindung vorgesehen, daß die Thermostate etwa in der Mitte der Preßplatte in den jeweiligen Zonen angeordnet sind. Diese Anordnung berücksichtigt gleichmäßigen Temperaturverlauf bei den zum Einsatz kommenden Heizplatten, die insbesondere in der sich aus dem Patent 27 27 300 der Anmelderin ergebenden Weise hergestellt sind.In a further embodiment it is provided according to the invention that the Thermostats arranged approximately in the middle of the press plate in the respective zones are. This arrangement takes into account a uniform temperature profile for the Use of upcoming heating plates, which can be found in patent 27 27 300 of the applicant's resultant manner are produced.
Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in Fig. 1 eine Aufsicht auf das Innere einer Heizplatte in vereinfachter Darstellung, Fig. 2 ein Schaltschema für den Heizstrom und Fig. 3 ein Schaltschema für den Meß- und Steuerstrom.The invention is illustrated below with reference to the drawing, for example explained in more detail. This shows in Fig. 1 a plan view of the interior of a heating plate in a simplified representation, FIG. 2 a circuit diagram for the heating current and FIG. 3 a circuit diagram for the measurement and control current.
Die allgemein mit 1 bezeichnete Heizplatte kann beispiels--weise in der Weise der Patentschrift 27 27 300 aufgebaut sein. Sie besteht aus einem Rahmen 2, in dem die nicht näher dargestellten, lediglich durch einen gekreuzten Kasten symbolisierten drei Heizkörper 3, 4und 5 innerhalb von mit 30, 40 und 50 bezeichneten Zonen der Heizplatte 1 angeordnet sind. Die Heizelemente liegen in einem Medium optimaler Wärmeleitfähigkeit eingebettet, was nicht näher dargestellt ist.The heating plate, generally designated 1, can, for example, be shown in FIG the manner of the patent 27 27 300 be constructed. It consists of a frame 2, in which the not shown, only by a crossed box symbolized three radiators 3, 4 and 5 within designated 30, 40 and 50 Zones of the heating plate 1 are arranged. The heating elements are in a medium embedded with optimal thermal conductivity, which is not shown in detail.
Der Rahmen 2 ist.mit--Händgriffen6 an den stirnseitigen Enden versehen. Stecker 7 zum--Kuppeln der Heizplatte an einem Heizstromkreis von z.B. 1000 Volt Wechselstrom und einem Meßstromkre½-s mit z.B. 2 Volt Gleichstrom, ist nur vereinfacht dargestellt.The frame 2 is provided with handgrips6 at the front ends. Plug 7 for - coupling the heating plate to a heating circuit of e.g. 1000 volts Alternating current and a measuring current circuit ½-s with e.g. 2 volts direct current is only simplified shown.
Im Bereich der Kupplung 7 in der mittleren Zone 40 im ersten Segment der Heizplatte, welches in Fig. 1 mit 8 bezeichnet ist, befindet sichein Widerstandstemperaturfühler 9, während zwei-Thermostate 10 und 11 in der -Plattenmitte in Segmenten 12 bzw. 13 der Zonen 30 bzw.In the area of the coupling 7 in the middle zone 40 in the first segment the heating plate, which is denoted by 8 in Fig. 1, is a resistance temperature sensor 9, while two thermostats 10 and 11 in the middle of the plate in segments 12 and 13 of zones 30 resp.
50 angeordnet sind. Die weiteren Plattensegmente sind in Fig. 1 niahtnäher-bezeichnet.50 are arranged. The other plate segments are denoted in greater detail in FIG. 1.
Aus dem Schaltschema &e.mäß Fig. 2. ergibt sich die Schaltung- der drei als elektrische Widerstandselemente ausgebildeten Heizkörper 3-, 4 und 5 und die jeweiligen. Phasen des Heiz-Wechselstromes "R", S und T.The circuit- the three designed as electrical resistance elements heating elements 3, 4 and 5 and the respective. Phases of the heating alternating current "R", S and T.
Das Schaltschema für den Meßstrom ist in Fig. 3 dargestellt mit dem Temperaturfühler 9 und den Thermostaten 10 und 11, die in der Reihenfolge 10, 9, 11 hintereinandergeschaltet sind.The circuit diagram for the measuring current is shown in Fig. 3 with the Temperature sensor 9 and the thermostats 10 and 11, which in the order 10, 9, 11 are connected in series.
Natürlich ist das beschriebene Ausführungsbeispiel der Erfindung nocii in vielfacher Hinsicht abzuändern, ohne den Grundgedanken der Erfindung zu verlassen. So kann insbesondere eine erfindungsgemäß aufgebaute Regelung und Temperaturüberwachung auch in jeder einzelnen Zone der Preßplatte angeordnet sein. Jede einzelne Preßplatte kann neben den in Fig. 1 dargestellten Zonen aus einer Mehrzahl von Zonen gebildet sein. Auch ist die Erfindung nicht auf die Größe der angegebenen Heiz- und Meßströme beschränkt.Of course, the described embodiment of the invention is nocii to change in many ways without departing from the basic idea of the invention. In particular, a control and temperature monitoring system constructed according to the invention can be used also be arranged in each individual zone of the press plate. Every single press plate can be formed from a plurality of zones in addition to the zones shown in FIG. 1 be. The invention is also not limited to the size of the specified heating and measuring currents limited.
