An automated plant for processing blood received from donations is central to operations at the new NHS Blood and Transplant Centre at Filton near Bristol.

Smart Manufacturing is using linear motion solutions from Parker Origa.

Before blood from donations can be delivered to the hospitals, the bags of blood are suspended from a bar for several hours under controlled conditions as an aid to filtration.

Once this stage of the process is complete the bags are ready for sealing, which is carried out manually.

To enable the work to be carried out at a convenient height for the operators, the bars from which the blood bags are suspended, which weigh around 15kg when fully loaded, must be raised by around 1.5m.

The design team decided to base its solution on the OSP-E BHD series of electric linear drives from Parker Origa.

BHD high-capacity linear-actuation systems feature a toothed-belt drive and have integrated guides to optimise load-carrying capacity.

The systems are available with recirculating ball-bearing guides or roller guides – the former being selected for this application.

Further benefits of the BHD systems are their compact design and the availability of a range of connection elements, accessories and mountings.

Parker Origa optionally offers BHD linear drive systems complete with motors and control systems.

Other options available include rodless pneumatic drives that are suited to reciprocating applications and electric-screw drives that combine high-force capability with accurate path and position control.

Parker-Origa, a division of Parker Hannifin, is a leader in the innovative design and manufacture of pneumatic and electric actuation and control solutions for industrial automation.

The Origa System Plus range of rodless pneumatic cylinders provides a modular approach to linear automation with the easy integration of guides, controls, position sensing equipment and other accessories. An extensive range of electric linear drives capitalises on this system modularity and extends the scope of application with respect to loads, speeds, precision, positional accuracy and path control.

With annual sales exceeding 12USD billion, Parker Hannifin is the world’s leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs approximately 62,000 people in 48 countries around the world. Parker has increased its annual dividends paid to shareholders for 52 consecutive years, among the top five longest-running dividend-increase records in the S&P 500 index.
