Embodiment Construction

[0029] exist figure 1 and figure 2 A sensor element 10 is shown as a component of a sensor system 100 which will be explained in more detail later. The sensor system 100 or the sensor element 10 is used in this case for ambient monitoring of a mechanical component, for example a moving robot arm of an industrial robot or the like.

[0030] as in particular based on figure 2 As can be seen, sensor element 10 has a layer structure consisting of a plurality of flexible layers connected to one another. The layer structure comprises, by way of example and thus without limitation, a base layer 11 , for example of rubber or foam rubber with a thickness of, for example, 5 mm. Two recesses 12, 13 are formed inside the basic layer 11 for receiving figure 1 and figure 2 Electronic devices or electronic components not shown in the The underside of the base layer 11 is here arranged, for example, on a mechanical component. Arranged on the upper side of the base layer 11 are two r...

Abstract

The invention relates to a sensor system (100) for monitoring surroundings on a mechanical component, having at least one capacitive sensor element (10; 10a; 10b; 10c) which can be mounted on the surface of machines or machine parts, wherein the at least one sensor element (10; 10a; 10b; 10c) is constructed from a layer structure of flexible, electrically conductive and electrically insulating plies (14, 15, 16, 17; 17a to 17c, 18; 18a to 18c, 19; 19a to 19c, 20; 20a to 20c), wherein electrically conductive potential surfaces of a ply are arranged with lateral spacing, via intermediate insulating plies, such that electrical field lines (1, 2) are formed between the conducting potential surfaces which alter measurably, when a body or an object approaches and / or comes into contact. The invention provides for the layer structure of a sensor element (10; 10a; 10b; 10c) to have at least two measuring elements (21, 22) which work separately from one another.

Description

technical field [0001] The invention relates to a sensor system for ambient monitoring of machine components according to the preamble of claim 1 . Furthermore, the invention relates to a method for exciting and analyzing the sensor system according to the invention. Background technique [0002] A sensor system according to the preamble of claim 1 is known from the later published DE 10 2009 029 021 A1 of the applicant. A sensor system that can be placed on a surface of a machine or a machine part has at least one sensor element that is formed from a layer structure of flexible, electrically conductive and electrically insulating layers. With the aid of such a sensor system, approaching and / or contacting of a body or an object can be measured in order, for example, to stop the operation of an assembly robot having the sensor system. [0003] Furthermore, it is known per se to use different sensor principles and sensors such as optical sensors, ultrasonic sensors or capaci...
