Problems solved by technology

[0005] However, in this way, the computational workload of the control device is very large, which hinders other computational work required for machine control in terms of operation
The large number of sensors in the control unit and the matching machine-specific algorithms are also quite costly, so this application has not been implemented on a large scale so far

Embodiment Construction

[0024] figure 1 Shows a schematic diagram of an injection molding machine with a plasticizing unit and a clamping unit, which are set in areas A (plasticizing unit) and B (clamping unit). The plasticizing unit in the area A includes a plasticizing cylinder 10 reciprocally supported on a bed 14 and includes an electric drive device 12 at its end. The mold clamping unit in the area B has two mold plates in a known manner, namely, a fixed mold plate 16 and a moving mold plate 18, on which a half mold 20 is respectively fixed. The template 18 is penetrated by four beams 22, among which figure 1 Only two can be seen in it. The moving template 18 can be fixed with respect to the beam 22 by the locking element 24, so that in the closed state of the clamping unit, a hydraulic pressure pad installed on the fixed template can be used to apply a clamping pressure. The sensors 30, 31 and 32 are respectively fixed on the two pressure pads and on the plasticizing cylinder 10 and the electri...

Abstract

Sensor (32) for injection molding machines or extruders comprises a probe (42) and an integral processing unit (44). The processing unit categorizes the signals it receives from the probe by comparison with a classification table and sends an error signal to a control unit if a defect is detected. An independent claim is included for: a method for operating a sensor, as described.

Description

Technical field [0001] The invention relates to a sensor for a machine for processing plastics and an operating method thereof. Background technique [0002] The present invention is particularly engaged in components used to identify abnormal states of components or machine parts in plastic processing machines, which states reflect functional failure, wear, or maintenance necessity. [0003] In recent years, people have been engaged in detecting abnormal operating conditions in machines in different technical fields, which reflect damaged machine parts or predicted functional failures. It is also increasingly hoped that, before actual malfunctions occur, they can understand especially maintenance and maintenance work. It is always more advantageous to avoid unintended damage by replacing potentially dying parts during the normal maintenance cycle than having to accept a relatively long unanticipated downtime in the event of an unexpected failure. [0004] Especially in automation ...
