Abstract
A sensor device for a rolling path insert of a track guide can be loaded by rolling bodies and is pressure-sensitive. The sensor device includes at least one tuple, extending in a rolling direction, of a number of sensors, which can each be signal-connected or are signal-connected to an evaluation device, by means of which a relevant difference signal can be determined from sensor signals of sensor pairs of the at least one tuple. The sensor device can be included in a rolling path insert, a guide carriage and a guide rail for a track guide, and a track guide.
Claims17
A sensor device for a rolling path insert of a track guide, the sensor device comprising:
- a plurality of sensors;
- at least one tuple, extending in a rolling direction, of the plurality of sensors;
- and
- an evaluation device to which each sensor of the plurality of sensors is signal-connected or is configured to be signal-connected, the evaluation device configured to determine respective difference signals from sensor signals of each sensor pair of a plurality of sensor pairs of the at least one tuple,
- wherein the sensor device is configured to be loaded by rolling bodies and is pressure-sensitive, and
- wherein at least two sensor pairs of the plurality of sensor pairs overlap one another in the rolling direction.
A sensor device for a rolling path insert of a track guide, the sensor device comprising:
- a plurality of sensors;
- at least one tuple, extending in a rolling direction, of the plurality of sensors;
- an evaluation device to which each sensor of the plurality of sensors is signal-connected or is configured to be signal-connected, the evaluation device configured to determine a relevant difference from sensor signals of sensor pairs of the at least one tuple,
- wherein the sensor device is configured to be loaded by rolling bodies and is pressure-sensitive,
- wherein at least two of the sensor pairs overlap in the rolling direction, and
- wherein the sensors or sensor portions of the tuple that have an odd ordinal number are each arranged offset in succession by a distance in relation to the rolling direction, said distance lying in a range around a quotient which is calculated from a rolling body diameter or rolling distance based on a number of sensor pairs.
A track guide comprising:
- an extending guide rail;
- a guide carriage which is roller-mounted on the extending guide rail and movable in an extension direction;
- at least one rolling path insert;
- rolling bodies arranged on the at least one rolling path insert between the guide carriage and the guide rail and configured to roll on the at least one rolling path insert;
- and
- a sensor device comprising:
- a plurality of sensors;
- at least one tuple, extending in a rolling direction, of the plurality of sensors;
- and
- an evaluation device to which each sensor of the plurality of sensors is signal-connected or is configured to be signal-connected, the evaluation device configured to determine respective difference signals from sensor signals of each sensor pair of a plurality of sensor pairs of the at least one tuple,
- wherein the sensor device is configured to be loaded by the rolling bodies and is pressure-sensitive, and
- wherein at least two sensor pairs of the plurality of sensor pairs overlap one another in the rolling direction.
