4 Applications Of Incremental Rotary Encoders In Packaging

Digital encoders cover a wide variety of movements in a given system. Be it linear encoders, absolute rotary encoders, incremental rotary encoders (also known as pulse encoders), or industrial angle encoders, these devices are known for their accuracy and precision in measuring the movement of the tool across a linear or rotary motion. Incremental rotary encoders, in particular, are used extensively in the packaging industry. In this blog, Walker Machinery, a leading distributor of Heidenhain encoders, explores 4 applications of these encoders in this particular sector.

Uses Of Incremental Rotary Encoders In Packaging

Web Tensioning

Web tensioning is important for maintaining packaging quality, especially for flexible packaging materials. Incremental rotary encoders achieve this by being attached to the arm of the tensioning roller. By closely monitoring the speed of the roller, the encoder can convey if proper web tensioning is maintained or not. If there is any discrepancy, the pulse encoder shares the feedback to the controller, which adjusts the drive motor to maintain even speed for proper tensioning.

Cut-To-Length

Be it flexible packaging materials or cartons, they need to be cut into a uniform size for effective operation. Pulse encoders ensure this by being mounted to the roller that sends out the cut material. In this manner, these digital encoders maintain accurate measurements of packaging materials.

Registration Mark Timing

This plays a vital role in labelling and packaging, as specific labels need to be placed on specific parts of the package. Incremental rotary encoders are used here as well to know the position of a particular unit with respect to another known point. 

Conveyor Systems

Conveyor systems are almost synonymous with the packaging industry. These pulse encoders are added to the conveyor motor or axles to monitor the movement of the overall conveyor to ensure a smooth flow of products.
