Abstract
The invention relates to a monitoring arrangement (12) for monitoring the clamping quality of a workpiece carrier clamped in a clamping device (3, 40, 49) as well as a clamping system with clamping device (3, 40, 49) and such a monitoring arrangement (12). The monitoring arrangement comprises at least two sensors (A1-A4) for the independent detection of the clamping quality of a clamped workpiece carrier or workpiece. The monitoring arrangement also comprises a transmitting device (14) and a receiving device (21), wherein the transmitting device (14) is constituted such that it transmits the determined or calculated parameter or parameters redundantly to the receiving device (21).
Claims23
A monitoring arrangement for monitoring the clamping quality of a workpiece carrier or workpiece clamped in a clamping device, with at least one sensor to be arranged on the clamping device and a transmitting device for the wireless transmission of parameters determined by means of the sensor to a receiving device, characterized in that the monitoring arrangement comprises at least two sensors for the independent detection of the clamping quality of a clamped workpiece carrier or workpiece, and that the transmitting device is constituted such that it transmits one or more determined or calculated parameters redundantly to the receiving device.
A method for monitoring the clamping device of a processing machine, characterized in that the quality of the clamping of a workpiece carrier or workpiece clamped in the clamping device is determined by means of at least two independent sensors, that measurement values determined by means of the respective sensors are compared with one another and checked for plausibility, and that one or more determined or calculated parameters is transmitted redundantly to a receiving device by means of a transmitting device and is transmitted by a gateway to a control of the processing machine.
