Bosch unveils latest version of rotary pen assembly machine MRA

At Achema, Bosch Packaging Technology showcased its latest version of the rotary pen assembly machine MRA. Developed by the Bosch subsidiary Moeller & Devicon, the machine is designed to assemble medical devices such as standard four-piece disposable pens or single-shot auto-injectors.

These are used, for instance, for diabetes care, the treatment of autoimmune diseases, hormone replacement therapies or emergency medicine. “We introduced the MRA to the market at last year’s Interpack in Germany. Since then, we have refined the technology by cooperating with several manufacturers of pens and auto-injectors, and have adapted the assembly processes for different models,” Michael Andersen, sales director at Moeller & Devicon, explained. “This way we can offer customers the appropriate machine with the required features according to the pens or autoinjectors in use.” Together with primary and secondary packaging solutions, the new MRA can be combined to complete lines.

Four pens at the same time

The MRA assembles the four components of each pen one step at a time: infeed systems load the pen caps, cartridge holders, cartridges and dosing mechanisms into the machine from four different in-feed stations, and fit them together to ready-to-use pens. The fully-automated machine handles four pens at the same time and achieves an output of up to 70 pens per minute. Incorrectly assembled products are automatically detected and rejected. A Human Machine Interface (HMI) enables operators to monitor all process functions precisely. The compact design and small footprint fully comply with GMP and Good Automated Manufacturing Practice).

Standard upstream and downstream options

As an option, the MRA platform can be combined with additional upstream and downstream equipment. For instance, the liquid pharma can be filled into cartridges and inspected for particles and cosmetic container defects on other Bosch equipment.

“The flexible and modular design of the MRA platform enables an upgrade with further process steps, such as laser engraving of the pens or serialization,” Andersen underlined. The entire range of rotary pen assembly machines by Moeller & Devicon is complemented by manual, semi-automated and fully automated linear solutions for all customer requirements.
