Wireless torque bottle

Why an instrumented bottle for checking the tightness of the caps?

To control the quality of tightening of closures in production, most of the time, the loosening torque on the bottles is measured after the closure has been screwed or pushed in by the capping machine. The results obtained are often very difficult to correlate with the actual appied torque during screwing for several reasons:

    The storage conditions of the bottle can impact the torque. For example, if the bottle is subjected to heat or cold, the materials will shrink or expand. These variations change the release torque.
    The unscrewing torque, if measured manually, can vary according to the operator, the speed of rotation, the force exerted on the cap...
    With the unscrewing control a maximum torque value is obtained but it is not possible to see what happens during rotation and locking.

To solve all these problems, Andilog has developed a wireless torque sensor that we integrate into bottles to directly measure the torque in production or during development.

Advantage of the wireless bottle:

• Real control of the screwdriver in production environment
• Facilitates the control of equipment and verification of the torques identified in the specifications during the design and acceptance of production lines
• Free from operator error
• Measurement with production plugs

How does wireless torque bottle work?

Wireless bottles are custom-made from the drawings of your bottles. We integrate a strain gauge torque sensor with a Bluetooth electronic board inside the bottle. Depending on the torque to be applied, production constraints and dimensions, we manufacture the bottles either in 3D printed plastic, stainless steel or aluminium.

The Bluetooth bottles are equipped with a battery that allows continuous measurement for up to 8 hours, allowing for long and repeated measurement campaigns. The range of the Bluetooth sensor integrated into the bottle is 20 meters (65ft) in an uninterrupted field. This range allows to the operator to stay easily connected to the bottle during its travel through the production line.

Andilog offers two solutions to display your measurements:

 

Computer software Caligraph:

Installed on a computer, Caligraph is a powerful yet simple solution for real-time acquisition of Andilog wireless sensors.

Caligraph integrates automatic calculations (maximum, minimum, average, break...) as well as funtions for creatin and editing reports.
