Abstract

Monitor which is independent of fluctuations in pressure, for a multi-component plastics metering machine, measures the amounts of the individual components being conveyed, compares them with the values of the other components per unit time, and interrupts conveyance in case of inadmissible differences. The monitor may be in the form of a pulse generator reacting to differential phenomena, with electronic control means to allow adjustment of admissible plus and minus tolerances in the metering ratio.

Description

Betr.: Beschreibung zur Patentanmeldung vom 26.11.1974 n von>n tæ= Dosier-Kontrll-System.-Erfindung eines neuen Kontrollsystems an Mehrkomponenten-Dosiermaschine zur Überwachung, Erfassung und Verhinderung von Dosierfehlern an Mehrkomponenten-Dosiermaschinen.Re: Description of the patent application dated November 26, 1974 n from> n tæ = Dosier-Kontrll-System.-Invention of a new control system on multi-component dosing machines for monitoring, recording and preventing dosing errors on multi-component dosing machines.

Das bisher angewandte System mit Drucküberwachungsmonometern war wie folgt aufgebaut: Drucküberwachungsmonometern schalten bei größerem Druckabfall (Förderstromunterbrechung) die gesamte Maschine aus.The previously used system of pressure monitoring monometers was like is structured as follows: Pressure monitoring monometers switch in the event of a greater pressure drop (flow interruption) the entire machine off.

Da auch Schwankungen während des exakten Dosierens vorkommen, können die Manometer nicht so sensibel eingestellt werden, daß die Maschine bei geringem Druckabfall, hervorgerufen durch Dosierverschiebungen, eventuell undichte Ventile, Dichtungen usw. auch ausgeschaltet wird.Since fluctuations can occur during the exact dosing the pressure gauges cannot be adjusted so sensitively that the machine runs at low Pressure drop, caused by metering shifts, possibly leaking valves, Seals etc. is also turned off.

Der Nachteil lag darein, daß nur auf Dosierfehler mit größerem Druckabfall, z.B. Materialmangel, reagiert werden konnte.The disadvantage was that only on metering errors with a larger pressure drop, e.g. lack of material, could be responded to.

Die Erfindung ist dadurch gekennzeichnet, daß: Ein besonderes, von Druckschwankungen unabhängiges Dosier-Kontroll-System, während des laufenden Betriebs der Maschine, die Mengenförderung der einzelnen Komponenten errnittelt, mit den Werten der anderen Komponenten pro Zeiteinheit vergleicht und bei unzulässigen Differenzen den Fördervorgang unterbricht.The invention is characterized in that: A particular, of Dosing control system independent of pressure fluctuations during operation of the machine, which calculates the volume of the individual components, with the Compares values of the other components per unit of time and in the event of impermissible differences interrupts the conveying process.

Dadurch können unzulässige Fehldosierungen, welche z.B. zu nicht aushärtenden Beschichtungen und Verklebungen bei Menrkomp-onenten-Kunststoffen führen und die damit verbundenen Schäden, vermieden werden.This can result in impermissible incorrect dosages, which, for example, lead to non-hardening Coatings and bonds with male component plastics lead and the associated damage, can be avoided.

Patentansprüche: 1 ) Die Anwendung des Dosier-Rontroll-Systems zur Erfassung, Auswertung und Sicheruna von Dosierströmen in Mehrkomponenten-Dosiergeräten.Claims: 1) The application of the dosing control system for Acquisition, evaluation and security of dosing flows in multi-component dosing devices.

2 ) Die Verwendung von Mengendurchflußmessaggregaten nach Anspruch l ), dadurch gekennzeichnet, daß sie als Impulsgeber für die Überwachung von Mehrkomponenten-Dosierströmen auf Differenzerscheinungen reagieren.2) The use of mass flow measuring units according to claim l), characterized in that it is used as a pulse generator for monitoring multi-component metering flows react to differences.
