Plastic Roll Diameter Measurement

Accurately determining the diameter of a roll of shrink wrap is essential to prevent material from running out during the shrink wrapping process and ensuring proper tensioning.

As pallets enter the shrink wrapping station, a reliable solution must provide accurate data to ensure the shrink wrap tension is what it should be and to alert operators if the roll of plastic wrap is empty.

YOUR BENEFITS

Maintain tensioning for correct wrapping and avoids machine jams.
Early warning that the roll is nearly empty.
Easy setup without having to unwind a complete roll.

Banner's LE550 Laser Sensor Provides Great Performance for Plastic Roll Diameter Measurement Applications

Banner Engineering’s LE550 is ready to measure right out of the box with easy adjustment, setup and use with a range of 100 to 1000 mm. If the range needs to be adjusted, the laser sensor has an intuitive user interface with a two-line, eight-character display, making it easy to automatically or manually adjust settings. The LE550 provides repeatability and accuracy across challenging targets, from metal to black rubber, allows for reliable measurement of the shrink wrap.

The analog output can be used to control wind or unwind speeds on the shrink wrap roll. The two point teach option can be used teach the outside of the roll as the 20 mA point and can easily be adjusted for a manual set of the 4 mA point to the core diameter. This allows easy adjustment without having to unwind the entire roll. The discrete output can also be utilized for a roll diameter application. It can alert operators that the roll is almost empty.

The LE550 has a remote input that allows for remote teaching, laser enable and advanced measurement modes to expand the range of applications solved with a single sensor. It is rugged, with a durable IP67-rated zinc housing that stands up to extreme industrial environments.
