Abstract

The lubrication control system for machines requiring lubrication in relation to the speed of the moving machine part, reduces the lubricant consumption. The control system has a sensor which measures the speed of the moving part in form of nominal value of a controlled driving arrangement. An analogous measureing signal in form of an AC voltage or current with positive or negative polarity is connected to threshold value-less rectifier and after that to a voltage frequency converter. A digital measuring signal, in form of a frequency or pulse sequence frequency is processed by a pulse generating stage. The frequency is fed into a frequency divider consisting of digital counting modules. After a lapse of a preset value the frequency divider produces an output signal switching on the lubricating time stage, which is inversely proportional to the dividing frequency and consequently to the measuring signal, producing a short lubricating interval at high speed and vice versa.

Titel: Geschwindigkeitsabhängiges, elektrischesTitle: Speed-dependent, electric

Schmiermittel steuergerät für Schmiereinrichtungen. Lubricant control unit for lubrication systems.

Anwendungsgebiet: Die Erfindung betrifft das elektrische Steuergerät einer Schmiereinrichtung für Maschinen, die einer geschwindigkeitsabhängigen Schmierung bedürfen (z.B. Bettschmierung einer größeren Werkzeugmaschine).Field of application: The invention relates to the electrical control device a lubrication device for machines that require speed-dependent lubrication require (e.g. bed lubrication of a larger machine tool).

Zweck: Bei bewegten Teilen hängt die benötigte Schmiermittelmenge von der Geschwindigkeit der Bewegung ab.Purpose: The amount of lubricant required depends on moving parts on the speed of the movement.

Zweck der Erfindung ist es, Schmiermittelmengen der Geschwindigkeit anzupassen. The purpose of the invention is to lubricate quantities of the speed adapt.

Stand der Technik: Zur Zeit sind nur Steuerungen für Schmiereinrichtungen bekannt, die rein zeitabhängig arbeiten. Die Schmierung erfolgt bei diesen Steuerungen nach Ablauf einer festen, von Hand einzustellenden Zeit.State of the art: At the moment there are only controls for lubrication devices known that work purely time-dependent. These controls are lubricated after a fixed time that can be set manually.

Kritik des Standes der Technik: Durch die rein zeitabhängige Schmierung werden unnütz Schmierstoffe verbraucht, da für unterschiedliche Bewegungsgeschwindigkeiten auch unterschiedliche Schmiermittelmengen erforderlich sind.Criticism of the state of the art: Due to the purely time-dependent lubrication unnecessary lubricants are consumed because of different speeds of movement different amounts of lubricant are also required.

Aufgabe: Die Aufgabe der Erfindung ist es, den Verbrauch an Schmierstoffen drastisch zu reduzieren.Task: The task of the invention is to reduce the consumption of lubricants drastically reduce.

Lösung: Die Aufgabe wird erfindungsgemäß so gelöst, daß ein Steuergerät aus einem der Geschwindigkeiten proportionalen elektrischen Meßsignal die Schmiermittelmenge steuert.Solution: The object is achieved according to the invention in such a way that a control unit the amount of lubricant from an electrical measurement signal proportional to the speeds controls.

Weitere Ausgestaltung der Erfindung: 3 Durch den Einsatz eines einstellbaren, digitalen Frequenzteilers kann der Zeitablauf mit Hilfe von Ziffernanzeigen dargestellt werden. Weiterhin beinhaltet das Steuergerät eine Alarmschaltung, die eine Störung des Schmierablaufes signalisiert.Further embodiment of the invention: 3 By using an adjustable, digital frequency divider, the timing can be shown with the help of numeric displays will. The control unit also contains an alarm circuit that indicates a fault of the lubrication process is signaled.

Erzielbare Vorteile: Der Einsatz der Erfingung verhindert die durch zu übermäßige Schmierung entstehenden Folgeschäden, wie Verunreinigung und Zersetzung von Fundamenten.Achievable advantages: The use of the invention prevents the through Damage such as contamination and decomposition resulting from excessive lubrication of foundations.

Die Optimierung der Schmierung reduziert die bisher erforderliche Schmiermittelmenge auf ein Minimum.The optimization of the lubrication reduces the previously required Lubricant amount to a minimum.

Die dadurch resultierende Kostenersparnis ist bei den ständig steigenden Rohstoffpreisen von gravierender Bedeutung.The resulting cost savings are constantly increasing Raw material prices of major importance.

Weiterer Vorteil des Gerätes ist die problemlose Nachrüstung älterer Schmiereinrichtungen.Another advantage of the device is the problem-free retrofitting of older ones Lubrication devices.

Beschreibung eines Ausführungsbeispiels: Die Erfindung ist ein Steuergerät (gemäß Blockschaltbild), das aus einem elektrischem, der Geschwindigkeit proportionalen Meßsignal eine Schmiereinrichtung steuert. Als geschwindigkeitsproportionales Meßsignal kann z. B. die Sollwertspannung eines geregelten Antriebs verwendet werden.Description of an exemplary embodiment: The invention is a control device (according to the block diagram), which consists of an electrical one proportional to the speed Measurement signal controls a lubricating device. As a speed-proportional measurement signal can e.g. B. the setpoint voltage of a controlled drive can be used.

Ein analoges Meßsignal, das eine Gleichspannung oder ein Gleichstrom positiver oder negativer Polarität ist, wird mit einem schwellwertlosen Gleichrichter und nachfolgendem Spannungsfrequenzwandler in eine dem Meßsignal proportionale Frequenz umgewandelt. Ein digitales Meßsignal - eine Frequenz oder eine Pulsfolgefrequenz -wird durch die Impulsformerstufe aufbereitet.An analog measurement signal that is a direct voltage or a direct current positive or negative polarity is made with a thresholdless rectifier and subsequent voltage frequency converter into a frequency proportional to the measurement signal converted. A digital measurement signal - a frequency or a pulse repetition frequency -Is processed by the pulse shaper stage.

Die entweder aus dem Spannungsfrequenzwandler oder der Impulsformerstufe kommende Frequenz wird einem einstellbaren Frequenzteiler zugeführt. Dieser Frequenzteiler besteht aus digitalen Zählbausteinen.Either from the voltage frequency converter or the pulse shaper stage The incoming frequency is fed to an adjustable frequency divider. This frequency divider consists of digital counting modules.

Nach Ablauf eines eingestellten Wertes (den Pausenzeitfaktor) erzeugt der Frequenzteiler ein Ausgangssignal, das die Schmierzeitstufe einschaltet. Die Schmierpausenzeit ist umgekehrt proportional der Teilerfrequenz, also auch umgekehrt proportional dem Meßsignal (z.B. große Geschwindigkeit ergibt kurze Schmierpausenzeit, kleine Geschwindigkeit ergibt lange Schmierpausenzeit).Generated after a set value (the pause time factor) has elapsed the frequency divider generates an output signal that switches on the lubrication timer. the The lubrication pause time is inversely proportional to the divider frequency, i.e. also vice versa proportional to the measuring signal (e.g. high speed results in short lubrication pause times, low speed results in long lubrication pause times).

Es ergibt sich folgende Beziehung: Schmierpausenzeit = Teilereingangsfrequenz (fe) Pausenzeitfaktor (n) Die Schmierzeitstufe steuert den Schmiervorgang.The following relationship results: Lubrication pause time = divider input frequency (fe) Pause time factor (n) The lubrication time stage controls the lubrication process.

Die Einschaltzeit der Schmierzeitstufe ist einstellbar.The switch-on time of the lubrication time stage is adjustable.

Die Schmiermittelmenge wird durch Einstellen der Schmierzeit den Erfordernissen angepaßt.The amount of lubricant is determined by adjusting the lubrication time as required customized.
