Mayr developed a new, extremely wear-resistant and almost maintenance-free generation of capping heads – for minimum downtimes and maximum plant availability.
The new, extremely wear-resistant plastic/stainless steel linear guide, which is lubricated for the entire lifetime of the product, reduces necessary servicing and maintenance costs to an absolute minimum. A simple visual inspection once a year is sufficient. And even better: No manufacturer service personnel are required for the inspection, in contrast to other commercially available capping heads. On-site employees can carry out the inspection themselves, and the top part of the capping head can be easily and quickly dismantled without requiring tools. This ensures substantially reduced standstill times and therefore high plant availability and productivity.
Contactless hysteresis technology
With the ROBA®-capping head, the hysteresis technology not only provides contactless and therefore wear-free torque transmissions: It is also impact-free and low-vibration, and thus guarantees a longer plant lifetime. The capping heads also feature a high torque repetitive accuracy of +/- 2%. With their continuous and impact-free closing torque, they are therefore the optimum choice for the application of plastic screw caps with preformed threads. They are better suited for the task than permanent magnet couplings with intermittent torque in slip operation, which in part “hammer down” the screw caps and make them hard to open. With the ROBA®-capping head, the limit torque can be easily and continuously adjusted, and can be read off directly via a scale. The enclosed construction also makes the capping heads resistant to dirt and aggressive media. It is possible to adapt the head pressure easily according to the customer requirements.
