Guide carriage for a route guide, route guide having the guide carriage and method for establishing a load of the guide carriage

A method for establishing a load of a guide carriage of a route guide, the route guide including (i) an extending guide having at least one guide roller track and (ii) the guide carriage that is supported on the extending guide and can be moved in an extending direction of the extending guide, the guide carriage including at least one carriage roller track paired with the at least one guide roller track and configured to enable rolling of roller members that are arranged between the least one carriage roller track and the at least one guide roller track, the guide carriage including a pressure-sensitive sensor device associated with the at least one carriage roller track and configured to be loaded by the roller members and to determine a load or wear acting on the guide carriage, the pressure-sensitive sensor device having a plurality of sensors arranged in a distributed manner in a rolling direction of the guide carriage, the plurality of sensors being connected so as to provide sensor signals thereof to an evaluation device, the plurality of sensors of the pressure-sensitive sensor device including at least one tuple of sensors that are directly sequential in the rolling direction and form at least one sensor pair that is configured such that, during an eccentric loading of the at least one sensor pair in the rolling direction, portions of the sensor signals of the at least one sensor pair that are dependent on disturbance variables are substantially identical, and portions of the sensor signals of the at least one sensor pair that are load-dependent are different, the method comprising:

• calculating the sensor signals per sensor pair of directly sequential sensors;
• determining, for each roller track, a respective load profile;
• and
• determining a load vector based on the load profiles of the roller tracks.

A guide carriage for roller-mounted guiding on a guide rail, the guide carriage comprising:

• at least one carriage roller track configured to enable rolling of roller members that are arranged between the guide carriage and the guide rail;
• and
• a pressure-sensitive sensor device associated with the at least one carriage roller track and configured to be loaded by the roller members and to determine a load or wear acting on the guide carriage, the pressure-sensitive sensor device having a plurality of sensors arranged in a distributed manner in a rolling direction of the guide carriage, the plurality of sensors being connected so as to provide sensor signals thereof to an evaluation device,
• wherein the plurality of sensors of the pressure-sensitive sensor device includes at least one tuple of sensors having three sensors that are directly sequential in the rolling direction and form two sensor pairs that are each configured such that, during an eccentric loading of each pair of sensors of the respective two sensor pairs in the rolling direction, portions of the sensor signals of each of the respective pair of sensors of the two sensor pairs that are dependent on disturbance variables are substantially identical, and portions of the sensor signals of each of the respective pair of sensors of the two sensor pairs that are load-dependent are different.

A guide carriage for roller-mounted guiding on a guide rail, the guide carriage comprising:

• at least one carriage roller track configured to enable rolling of roller members that are arranged between the guide carriage and a guide rail;
• and
• a pressure-sensitive sensor device associated with the at least one carriage roller track and configured to be loaded by the roller members and to determine a load or wear acting on the guide carriage, the pressure-sensitive sensor device having a plurality of sensors arranged in a distributed manner in a rolling direction of the guide carriage, the plurality of sensors being connected so as to provide sensor signals thereof to an evaluation device,
• wherein the plurality of sensors of the pressure-sensitive sensor device include at least two tuples of sensors arranged spaced apart from each other along an extent of the roller track, each tuple of sensors of the at least two tuples of sensors being arranged directly sequential in the rolling direction and to form at least one sensor pair that is configured such that, during an eccentric loading of the at least one sensor pair in the rolling direction, portions of the sensor signals of the at least one sensor pair that are dependent on disturbance variables are substantially identical, and portions of the sensor signals of the at least one sensor pair that are load-dependent are different.
