Description
Die Erfindung betrifft eine Spritzgießmaschine mit einem Kraftsensor zur Bestimmung des auf die Schnecke der Spritzgießmaschine ausgeübten Stau- und/oder Einspritzdrucks.The The invention relates to an injection molding machine with a force sensor for determining the on the screw of the injection molding machine exerted Accumulation and / or injection pressure.
Bei einer Spritzgießmaschine wird während des Plastifiziervorgangs von der Schnecke Kunststoffmaterial aufgeschmolzen und in den Schneckenvorraum gefördert. Wenn die Schnecke als Schubschnecke ausgebildet ist, mit der die Kunststoffschmelze in das Werkzeug der Spritzgießmaschine eingepritzt werden soll, wird die Schnecke während des Plastifiziervorgangs zunächst nach hinten und für das Einspritzen anschließend nach vorne bewegt. Während des Plastifiziervorgangs wird von der im Schneckenvorraum befindlichen Kunststoffschmelze ein sogenannter Staudruck auf die Schnecke ausgeübt, der im Kraftfluss zwischen der Schnecke und dem Schneckenantrieb zu einer geringen Verformung der im Kraftfluss befindlichen Bauteile führt. Aus dieser Verformung kann die auf die Schnecke ausgeübte Kraft und über den Querschnitt der Schnecke der Staudruck im Schneckenvorraum bestimmt werden. In gleicher Weise, allerdings um ein Vielfaches höher, führt der während des Einspritzens im Schneckenvorraum herrschende Einspritzdruck zu einer Verformung der im Kraftfluss befindlichen Bauteile, so dass durch Messung der Verformung die auf die Schnecke beim Einspritzen ausgeübte Kraft und über den Querschnitt der Schnecke der Einspritzdruck bestimmt werden kann.at an injection molding machine will be during the Plasticizing process by the screw plastic material melted and promoted into the worm anteroom. If the screw is designed as a screw, with which the Plastic melt are injected into the mold of the injection molding machine should, the snail is during the Plasticizing process first to the back and for then injecting moved forward. While the plasticizing process is located in the worm room Plastic melt exerted a so-called back pressure on the screw, the in the power flow between the worm and the worm drive too a small deformation of the components located in the power flow leads. Out This deformation can affect the force exerted on the worm and over the cross-section of the screw determines the dynamic pressure in the antechamber become. In the same way, but many times higher, leads the while injection pressure prevailing in the antechamber a deformation of the components in the power flow, so that by measuring the deformation on the screw during injection practiced Power and over the cross-section of the screw, the injection pressure can be determined can.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Spritzgießmaschine anzugeben, bei der der Stau- und/oder Einspritzdruck (allgemein der Druck im Schneckenvorraum) sowohl mit hoher Präzision als auch auf vergleichsweise einfache Art und Weise bestimmt werden kann.outgoing This is the object of the invention, an injection molding machine indicate at which the congestion and / or injection pressure (generally the pressure in the antechamber) with both high precision and be determined in a relatively simple manner can.
Die Lösung dieser Aufgabe erfolgt durch eine Spritzgießmaschine mit den Merkmalen von Patentanspruch 1. Vorteilhafte Ausgestaltungen und Weiterentwicklungen finden sich in den Unteransprüchen. Da der Erfindungsgedanke nicht auf die Messung des Stau- und Einspritzdrucks bei einer Spritzgießmaschine beschränkt ist, sondern prinzipiell auch bei anderen dreh- und linearangetriebenen Maschinenteilen zur Anwendung kommen kann, sind diesbezügliche nebengeordnete Ansprüche 15 bis 25 vorgesehen.The solution This object is achieved by an injection molding machine with the features of claim 1. Advantageous embodiments and further developments can be found in the subclaims. Since the idea of the invention is not based on the measurement of the accumulation and injection pressure at an injection molding machine limited is, but in principle also in other rotary and linear driven Machine parts can be used, are in this regard sibling claims 15 to 25 provided.
Dadurch, dass der Kraftsensor zwischen dem hinteren Ende der Schnecke und der Antriebswelle der Schnecke angeordnet ist, ist dieser einfach zu montieren und – im Gegensatz zu Kraftsensoren im Innern der Schnecke – leicht zugänglich. Zur Auswertung der Signale sind weiters ein mit der Schnecke bzw. der Antriebswelle mitrotierender Messwertverstärker sowie ein mit der Schnecke bzw. der Antriebswelle mitrotierender Sender vorgesehen. Der Messwertempfänger kann drehfest, insbesondere ortsfest an einem Gehäuseteil vorgesehen sein.Thereby, that the force sensor between the rear end of the screw and the drive shaft of the screw is arranged, this is easy to assemble and - in Contrary to force sensors inside the snail - light accessible. To evaluate the signals are further one with the screw or the drive shaft mitrotierender measuring amplifier and one with the screw or the drive shaft co-rotating transmitter provided. The measured value receiver can rotatably, in particular be provided fixed to a housing part.
Zur Übertragung
der Messwerte von dem rotierenden Sender auf den ruhenden Empfänger können prinzipiell
Schleifring- oder Induktivübertrager vorgesehen
werden. Sowohl Schleifring- als auch Induktivübertrager sind für Rotationsbewegungen
ausgelegt. Wenn allerdings auch Axialbewegungen zwischen dem Sender
an der Schnecke bzw. der Antriebswelle und dem ruhenden Empfänger erfolgen, wie
dies beispielsweise bei einem Antrieb gemäß
Zur Energieversorgung der drehenden Teile wie Kraftsensor, Messwertverstärker und Sender können, sofern keine axiale Bewegungen dieser Teile erfolgen sollen, die oben erwähnten Schleifring- und Induktivübertrager vorgesehen werden.to Power supply of rotating parts such as force sensor, measuring amplifier and Transmitters can, if there are no axial movements of these parts, the mentioned above Slip ring and inductive transformer be provided.
Um unabhängig davon zu sein, ob nur eine Drehbewegung oder zusätzlich auch eine axiale Relativbewegung zwischen den rotierenden Teilen der Messeinrichtung und den ortsfesten Teilen vorliegt, können zur Energieversorgung mitrotierende Solarzellen vorgesehen werden, die von ortsfesten Lichtquellen bestrahlt werden.Around independently to be, whether only a rotational movement or in addition, an axial relative movement between the rotating parts of the measuring device and the fixed ones Sharing is present be provided for power supply mitrotierende solar cells, which are irradiated by stationary light sources.
In einer vergleichsweise einfachen Ausgestaltung ist vorgesehen, das der Kraftsensor an der Kupplung zwischen dem hinteren Ende der Schnecke und der Antriebswelle angeordnet ist und dass auf dieser Kupplung eine Scheibe angebracht wird, auf der die weiteren rotierenden Teile wie Messwertverstärker, Sender und Solarzellen befestigt sind. Der Empfänger für die Messwerte und die Lichtquellen für die Solarzellen können an geeigneten Stellen ortsfest im Gehäuse untergebracht werden.In a comparatively simple embodiment is provided, the the force sensor on the coupling between the rear end of the screw and the drive shaft is arranged and that on this clutch a disc is attached, on which the other rotating parts like measurement amplifier, Transmitter and solar cells are attached. The receiver for the measured values and the light sources for the Solar cells can be accommodated in suitable places stationary in the housing.
Es kann also eine Messkette aufgebaut werden, bei der sowohl die Messwertübertragung als auch die Energiezuführung berührungslos erfolgt. Damit ist man in der Anbringung des Empfängers völlig frei, d.h. es spielt keine Rolle, ob zwischen dem Empfänger und dem Sender eine rotatorische und/oder translatorische Relativbewegung erfolgt. Ebenso ist man in der Energieversorgung von solchen Relativbewegungen zwischen der Energiequelle und dem Verbraucher unabhängig, wenn die Energieversorgung mit mitrotierenden Solarzellen erfolgt, die von ortsfesten Lichtquellen bestrahlt werden.It Thus, a measuring chain can be set up in which both the measured value transmission as well as the energy supply contactless he follows. This one is completely free in the attachment of the recipient, i.e. it does not matter if there is a rotatory and / or translational relative movement takes place. Likewise, one is in the power supply from such relative movements between the energy source and the Consumer independent, if the energy supply takes place with co-rotating solar cells, the be irradiated by stationary light sources.
