Splice Detection in a Paper Roll

Splice Detection in a Paper Roll Image

Application: Sensing splices on a roll of paper

Challenges: Detecting splices at a very high speed

Solution: The R58 Expert registration mark high color resolution sensor

Benefits: Creates optimal contrast and has a fast 10 kHz switching frequency

Identifying splices on a roll of paper quickly and reliably is vital, as it is now common to come across multiple splices on one roll. Splices and other defects need to be detected so they are not included as a part of the final product.

Description

Banner’s R58 Expert registration mark high color resolution sensor is a high-performing sensor with an ultra fast 10 kHz switching frequency that quickly detects splices and other defects that are otherwise hard to detect. The high sensitivity of the R58 Expert detects the inconspicuous splice in a roll of paper to ensure the printer skips over the splice during the press process.

The R58 Expert sensor makes it easy to create optimal contrast for splice detection applications because it automatically selects the appropriate LED, helping to increase product quality and minimize operator intervention. The R58 Expert also provides simple data monitoring with an easy-to-read 8-segment bargraph display indicator for TEACH and signal strength readout and for continuous readout of output status.

The R58 Expert has a heavy-duty, rugged zinc alloy die-cast housing for use in industrial and wash-down environments. The R58 Expert has models available for a parallel or perpendicular sensing image, depending on the setup and application need.
