Abstract
Bei einer Vorrichtung zum Ermitteln von Messgrößen in einem Spritzgieß-Werkzeug mit einem Messelemenik verbunden ist, soll dem Messelement in dem Spritzgießwerkzeug eine Sensoridentifikation zugeordnet sein.In a device for determining measured variables in an injection mold with a Messelemenik is connected to the measuring element in the injection mold to be assigned a sensor identification.
Description
Die Erfindung betrifft eine Vorrichtung zum Ermitteln von Messgrössen in einem Spritzgiess-Werkzeug mit einem Messelement, das mit einer Auswerte- und/oder Steuerelektronik verbunden ist.The The invention relates to a device for determining measured variables in an injection molding tool with a measuring element, which is equipped with an evaluation and / or control electronics is connected.

Aufgabetask
Aufgabe der vorliegenden Erfindung ist es, eine kostengünstige und benutzerfreundliche Vorrichtung der vorgenannten Art zu entwickeln.task The present invention is a cost effective and develop user-friendly device of the aforementioned type.
Lösung der AufgabeSolution of the task
Zur Lösung der Aufgabe führt, dass dem Messelement in dem Spritzgiesswerkzeug eine Sensoridentifikation zugeordnet istto Solution of the task that leads to the measuring element assigned a sensor identification in the injection mold is
Es wird von einem Sensor bis zu einer Werkzeugwand ein koaxiales Anschlusskabel verwendet, welches ohne Graphitschicht lediglich aus einem Heissleiter und einer Schirmleitung besteht. Die Schirmleitung wird hierbei zur Übertragung der Sensoridentifikation verwendet.It From a sensor to a tool wall is a coaxial connection cable used, which without graphite layer only from a hot conductor and a shield line exists. The shield line is hereby used to transmit the sensor identification.
Es wird davon ausgegangen, dass sich das Kabel während des Messvorgangs nicht bewegt, weshalb auf eine Graphitschicht verzichtet wird.It It is assumed that the cable is disconnected during the Measurement process is not moved, which is why dispense with a graphite layer becomes.
Ausserdem wird davon ausgegangen, dass das Kabel vollständig und permanent von Metall umgeben ist, weshalb eine Erdung bis zur Werkzeugwand gewährleistet ist.Moreover It is assumed that the cable is complete and is permanently surrounded by metal, which is why a grounding to the tool wall is guaranteed.
Von der Werkzeugwand bis zu einer nach geschalteten Elektronik (Ladungsverstärker) werden Standard-Verbindungskabel verwendet, die über eine weitere Schirmleitung sowie über eine Graphitbeschichtung auf dem Heissleiter verfügen. Durch diese zusätzliche Schirmleitung wird die Erdung von Werkzeug/Sensor auf den Verstärker übertragen.From the tool wall to a downstream electronics (charge amplifier) Standard connection cables are used which have one additional shielding and a graphite coating on the hot conductor. Through this additional Shield cable is the grounding of tool / sensor transmitted to the amplifier.
Durch die Graphitbeschichtung werden die Störeffekte beim Bewegen des Kabels vermieden.By the graphite coating will be the disturbing effects when moving of the cable avoided.
Vorteil dieser Anordnung ist, dass der Anwender das Anschlusskabel (Koaxkabel) am Sensor leicht reparieren kann, wobei gleichzeitig eine optimale Signalqualität gewährleistet ist.advantage this arrangement is that the user the connection cable (coaxial cable) easy to fix on the sensor, while maintaining an optimal Signal quality is guaranteed.
Ausserdem ist dies eine kostengünstige Variante, da sowohl bestehende Verbindungskabel als auch bestehende Verstärker verwendet werden können. Es ist keine Modifikation der Elektronik durch zusätzlichen Schalter notwendig.Moreover This is a cost effective option since both existing ones Connection cable as well as existing amplifiers used can be. It is not a modification of the electronics necessary by additional switch.
