Mayr Bremse AntriebstechnikSPS hall 4, booth 278

Mayr Antriebstechnik introduces new versions of the "Roba-brake-checker "module with which even small brake sizes can now be monitored. This opens up new possibilities for brake monitoring - especially for spring-applied brakes in servomotors and for applications in robotics and automation.

The Roba-brake-checker monitors and supplies Safety brakes sensorless and provides data for the intelligent safety of the following series: With the "Roba-power stop"Series (picture) is a powerful safety brake for installation in servomotors available. A special hollow shaft design with a slim design and low weight is tailored to the requirements of robotics. The "Roba-linearstop"In electromagnetic design is a fluid-free linear brake to secure gravitationally loaded vertical axes. It is used in applications where no compressors or units for compressed air or oil hydraulics are available or are undesirable. Applications can be found z. B. in medical technology, food or pharmaceutical industry, where high standards of hygiene are required.

mayr11019The intelligent Roba-brake-checker module now also opens up new opportunities for brake monitoring in these areas. Because with a new version of the module, thanks to even finer evaluation, even small brake sizes can be supplied and monitored from a braking torque of 2 Nm. Today, the Roba-linearstop is not only the only electromagnetic bar brake on the market, but can now also be monitored in the smaller sizes with the aid of the module.

The Roba-brake-checker recognizes the movement of the armature disk by means of an extended analysis of current and voltage and knows in which state the brake is located. In addition to switching status, temperature and wear, it also monitors the pull-cord or tension reserve, ie whether the magnet is still able to attract the armature disk. With the new module, significantly more parameters are now displayed during monitoring than with microswitches and initiators. When the traction reserve is reached, the module sends a warning signal so early that a certain operating time of the brake is still possible. In addition to the pure signal, the module can be connected via z. For example, an optical interface can provide data on switching time, current, voltage, resistance, power, and relative pull-in current. The latter allows conclusions about critical operating conditions of the brake.

Via an evaluation program the user can see if everything fits or if there is something to do. In addition to the scheduled maintenance, the error output also enables remote maintenance in the event of a problem.

More news from Mayr power transmission

  • Hannover Messe Hall 5, Stand E04 Intelligent machine elements provide important measurement data for transparency in the drive train. This is how they support efficient and predictive machine maintenance. At the Hannover Messe 2020, Mayr Antriebstechnik presents intelligent solutions for brake monitoring as well as new approaches for networked clutches. The drive specialist invites visitors to think along the new paths.
  • User report The largest machines that are currently digging underground on the construction site of the Semmering base tunnel are two tunnel boring machines. The EAS-HT safety coupling from Mayr power transmission is used to protect these heavyweights. These couplings trigger reliably and understandably and protect the drive components sustainably. They cannot be manipulated and the factory-set torque is available again even after disengagement. Recommissioning is also quick and easy, without additional tools.
  • FMB Hall 20, Stand C31; SPS Hall 4, Booth 278 User report The cheese production facilities are just as mature as the delicatessen itself. The French manufacturer of production lines for the production of cheese and milk products Chalon Mégard relies on reliable linear brakes from Mayr Antriebstechnik in its machines. The corrosion-protected brake systems easily withstand the operating conditions in the food industry and ensure, for example in a vertical conveyor system, that the heavy cheese wheels do not fall.
  • SPS Hall 4, Booth 278 Mayr Drive Technology presents new versions of the "Roba-brake-checker" module, which can now also be used to monitor small brake sizes. This opens up new possibilities for brake monitoring - especially with spring-applied brakes in servomotors and for applications in robotics and automation.
  • FMB, Hall 20, Stand C31 Cover story The traditional family company Beyer Maschinenbau plans, develops and builds efficient packing and palletizing systems for the beverage and food industry. The patented "Roba-DS" multi-plate pack couplings from Mayr power transmission transmit precise torques in these systems. In lifting applications, the “Roba-linearstop” safety brakes reliably ensure the safety of people and materials.
  • Motek Hall 6, Stand 6324 Mayr Antriebstechnik presents backlash-free shaft couplings for all drive configurations and reliable safety brakes for vertical axes. There are innovations in the standard modular system. The intelligent monitoring module "Roba-brake-checker" comes up with new versions. It monitors and supplies safety brakes without sensors and provides data for safety.
  • With its clutches and brakes, EMO Hall 8, Stand E45 Mayr Antriebstechnik offers complete solutions from a single source for the reliable protection of machine tools and machining centers. For example, a wide range of backlash-free, powerful servo couplings ensures a secure connection between the shafts. And a wide portfolio of reliable safety brakes is available to protect gravity-loaded axles.
  • The Mayst power transmission engineering company from Mauerstetten celebrates the 25th anniversary of its location in Poland. The former small manufacturing facility has now developed into a modern, efficient industrial company with around 400 employees - with active support from the Allgäu region.
