Asian Pulp and Paper Acquires R.K.B.

Reject Gate Control Technology


Reject Gate Control TechnologySyracuse, NY, July 20, 2009 - R.K.B. OPTO-ELECTRONICS, INC., A world leader in machine vision and web inspection design and supply, has received an order for its state-of-the-art Model 1122 Abolisher® Reject Gate Control™ Technology.  The equipment will be implemented on an Accura sheeter/sorter  and integrated into R.K.B. Model 1088 Sentinel® Splice Detector™ Technology to ensure that each and every splice (joint) fault defect is rejected prior to stacking.  Simple and cost effective, the Model 1122 Abolisher® Reject Gate Control™ Technology will out perform any software devised technique currently in use by many leading sheeter/sorter manufacturers.  This Model 1122 Abolisher® Reject Gate Control™ Technology will guarantee the reject of all splice defects with an average return on investment less than 30 days.  In this particular application, the Model 1122 Abolisher® Reject Gate Control™ Technology has been acquired by Asian Pulp and Paper Company, Pindo Deli Division located in Java, Indonesia.    


The Model 1122 Abolisher® Reject Gate Control™ Technology interfaces with a wide variety of web inspection, processing, and material handling equipment to provide automatic sorting or rejection of defective material. A precision encoder, combined with the unit’s digital memory, makes it possible for the unit to determine how many complete sheets and fractional sheets are between the inspection system and the reject gate.  Since the precision encoder is hard coupled to the drive knife, system accuracy is not speed dependent.  The Model 1122 Abolisher® Reject Gate Control™ Technology is designed to ensure that only sheets with defect faults are rejected. It can be used to process multiple products of differing lengths through front panel switch settings. A margin inhibit switch can be used to disengage the reject mechanism when a defect falls within 1/4 inch (6.35 mm) of the cut line (i.e., within a margin which will be trimmed later). If a large defect occurs that spans multiple sheets, the Model 1122 Abolisher® Reject Gate Control™ Technology ensures that all defective sheets are rejected.  Reject Accuracy of this unit is 1/64" Max. (0.4 mm Max.) with a Margin Inhibit Range of 0.5 to 1.5% of Sheet Length.  Input to the device is a 9-12 VDC Pulse from defect detection equipment with outputs of 2.0 Amp at 20 VDC, DPDT Relay Contact @ 5.0 Amp rating or an option DPDT Relay Contact rated at 10.0 Amps.  Primary power to the Model 1122 Abolisher® Reject Gate Control™ Technology is 120VAC through an R.K.B. supplied constant voltage regulator/power conditioner.  Total power consumption including reject solenoids is 50 watts or less.   The R.K.B. Model 1122 Abolisher® Reject Gate Control™ Technology can be combined with R.K.B. inspection equipment to form an integrated, single source, system for your sorting and inspection applications. The technology is also compatible with a wide variety of third party sensors and web inspection equipment to meet diverse needs. We can provide expert design, system integration, installation, and support to ensure success with your project.  Choose the R.K.B. Model 1122 Abolisher® Reject Gate Control™ Technology for faster, more reliable control of delivered product quality.


R.K.B. pioneered the field of web inspection for web based paper, film, foil and allied material manufacturing.  R.K.B. developed and patented many of the technologies currently in use today such as infrared phototransistor flaw detection technology, inductive and capacitive detection technology, ultraviolet phototube hole detection technology and camera based machine vision web inspection technology.  In fact, R.K.B. was the first company in the world that incorporated camera sensors for the detection of defect faults in web material in the mid 1970's and patented this technique called the VIDISCAN 7000.  Today R.K.B. invests a majority of its capital to research and development in new defect fault detection sensor techniques.  Among our many innovations besides our patented splice detection technology, which is the world leading technology used for the detection of splice (joint) tape faults, is our very successful patented Model 3020 OPTOMIZER® Coating Streak/Scratch Inspection Technology.  This technology, now being emulated and copied (badly we might add), by various European inspection solution suppliers, detects streaks and scratches as small as 1 micron (0.000039 inches (0.001 millimeter)) wide at any known process speed.  This is not only theoretical proven, but proven online at various coated paper makers worldwide.  Refer to the three studies provided herein for customer verification of the success of our streak detection technology which can be found at the following links "European Coated Board Installation", "Consolidated Papers Inc., On-line Evaluation Verification" and the comparative study done by the "American Forest Products Association in conjunction with the Institute for Paper Science and Technology".  These three vital documents were produced in a bipartisan process by each of these companies.  R.K.B. OPTO-ELECTRONICS, INC., designs, develops, manufactures, and markets the most diverse line of machine vision and web inspection technologies currently available to web based material manufacturers. R.K.B., has offices and partners worldwide in Asia, Europe, South America and the Middle East.
