Work piece position monitored
pneumatically
A pneumatic position monitoring unit can be used for controlling the presence or dimensional accuracy of work pieces in automation systems.
Rexroth is offering a pneumatically operated controlling and measuring system, the MS01, to control the presence, position, form or dimensions of test objects during automatic supply and processing of work pieces In numerous pneumatic applications, the compressed air required for pneumatic functions is used in two ways, as follows

Robot controls have high functionality
High functionality is combined with minimal space requirements in the rho4.0 robot and handling control introduced by Bosch Rexroth.
1 -Pneumatic components are operated with compressed air.
2- Using non-contact scanning of a test object with an air jet from a sensor nozzle and the evaluation of the resulting dynamic pressure, a statement in the form of an electric signal can be made about the factors, which are being tested.
For these types of applications, Rexroth offers the pneumatic position monitoring unit MS01.
The pneumatic position monitoring unit can be used for controlling the presence or dimensional accuracy of work pieces.
Measuring nozzles conduct non-contact scanning of the test object.
The dynamic pressure which forms between the work piece and the measuring nozzle indicates the presence or dimensional accuracy of the work piece.
A signal transmits the measurement result to the machine controller; cases of defective work pieces or incorrect positioning are shunted out of the process.
In a different application, the position monitoring unit controls the presence of bores in the work piece.
Air is blown through a measuring inlet into the nozzle area of a scanning sensor.
If a bore is missing, the predefined dynamic pressure is too low and a signal is sent to the machine controller stopping further processing of the defective work piece.
The pneumatic position monitoring unit from Rexroth features a high measurement accuracy of up to 0.01 mm.
To guard against the corruption of measurement results by contaminants such as chips or coolant, the MS01 is equipped with an integrated cleaning pressure function.
This ensures regular cleaning of the measuring surface.
The system can be easily expanded.
As a joint solution in combination with the CD01 valve system, the MS01 position monitoring unit can be integrated in any machine controller, equating to a minimum of assembly and installation effort for the user.
