A multinational leading company in the home appliance industry

IMPROVED ERGONOMICS IN THE PRODUCTION LINE WITH THE BRV40-SA AND SA ARTICULATED SUPPORT, WITH SPECIAL TOOL HOLDER

Our customer, a multinational leading company in the home appliance industry, was looking to improve the safety and the health of its workers by eliminating the ergonomic risks to which they were subjected during the tightening phase, reducing their daily weariness.

In this case, during the process the operator performs 3000 tightening per shift, using an auto-feeding pneumatic screwdriver for fixing the bottom side of the refrigerator.  A considerable stress on his wrist.

The customer asked for replacing it with a tool for tightening on the horizontal axis, in order to allow more mobility in the working area and resistance to frequent and prolonged use over time.

The solution proposed is a BRV40-SA torque tube arm with SA articulated carbon fiber support, which allows maximum freedom of movement in the working area. The BRV40-SA  torque tube reaction arm holds the reaction due to the tightening torque (of 6Nm) and thanks to a "special tool holder", customized by our technical department, a perfect parallelism to the floor of the screwdriver and an easy screw inlet is guaranteed.

Improvement of physical ergonomic parameters leads to worker stress reduction and ensures efficiency improvement in the tightening phase at the same: in fact, cycle time was not increased compared to the previous situation without the reaction arm. Reducing the operator's effort, the system allows even elderly or female staff to work efficiently and comfortably, guaranteeing flexibility in the resources management.

Target

Eliminate ergonomic risks for workers in the tightening phase subjected to high physical stress, reducing fatigue and daily effort. Perform tightening on a horizontal axis, with mobility in the work area and resistance to frequent and prolonged use over time.
