Solutions
Electric screwdrivers are characterised by a high degree of flexibility and infinitely variable controllability. This means Stein-Automationstechnik is no longer limited to one screw length but can use several screw lengths in the same system. The Series 5ES linear axes achieve a positioning accuracy of 50 µm. The torque and feeding speed can also be quickly adapted to the type of screws and material. The electrical solution is recommended for safety reasons, as no unexpected movement of the workpiece or other components can occur. The only pneumatic component in the machine is a cylinder that serves to separate the screws and feed them in with the help of the vibration plate.
Results
The Series 5ES linear axis is the heart of the Swiss solution: "The most suitable and fastest unit is the one from Camozzi," Stein points out. The 30 Nm motor should screw the screws into the timber walls in just 4–5 seconds – now it can be done in 3 seconds. Since the 5ES linear axis is extremely stable, it can also be used safely with powerful and heavy 5000 rpm and 30 Nm motors. The linear unit is also robust enough to work flawlessly for many years under constant stress from heat and chips. A stainless steel sealing strip is used to seal the profile to the outside. This and a felt wiper below the plastic cover ensure that no chips get inside the axis.
Stein does not yet know what challenges the next project will bring, but one thing is already clear: "if at all, then only with Camozzi!" confirms the entrepreneur.
