To achieve that, a rotating blade is used. It is made up of an electric resistance that heats the sealing blade and the temperature is monitored by a thermocouple temperature sensor embedded in the blade. A slip ring is then used in order to feed the electrical resistance and retrieve thermocouple signals between the rotating blade and the computer side.

Slip ring are the best way to wire components that move. Indeed, cable carriers often induce cinematic constraints and low reliability thatSlip ring make disappear. 

Low friction torque ofSlip ring mitigates the mechanical impact and continuous rotation capabilities make programming simpler.

Rotation movement takes place at nearly every step of the process from bottle conveying to label placing. Sometimes, active components are embedded on a rotating plate and linked to the machine computer. Slip ring can perform this link while offering continuous rotation capabilities. Continuous rotation increase machine performance and reliability while easing the machine design.Slip ring can transfer all signal that can be met in such machines, motor power and control, sensors, field buses, etc.

The common link, regardless of the final application, is the use of a Slip Ring or a Rotary Union. Cable reels usually transmit power and electric signals, data and different kind of fluids; instead, in case of high-frequency signals, high data rate or where a low bit error rate (BER) is required, the proper result is achieved with a fiber optic rotary joint. Our product range can cover nearly all application from power signals to high data rate or optical signals for cables and from pressurized air to hydraulic oil for rotary union.

Those operations require special tooling that needs to be accurately handled and monitored with dedicated sensors in order to ensure repeatability. PES has already implemented tool changing systems for such special operations. Our custom module design and manufacturing capabilities help us to adapt to any kind of equipment that is present on the robot end-of-arm while the cam lock mechanism with integrated wear compensation ensure the accuracy and repeatability that riveting or gluing applications need.

When using a tool changer with tools that embed such cameras, the major challenge is to transfer the high data rate video signal through the tool changer quick connection.

From standard 100Base-TX Ethernet to GigE Vision application, PES always provides the proper electrical interface to meet the communication standard requirement.

Sometimes we also integrate contact redundancy for increased availability of the video link.
