March 19, 2009 - R.K.B. OPTO-Electronics released of its new Sentinel Splice (Joint) Detection Technology. The Sentinel monitors 1-16 webs of material and will detect any splice or joint that may exist within the web based process.
It is applicable to manufacturing processes that require the culling out of splices or joints prior to shipment. As a control in subsequent conversion processes, it prevents damage to sensitive equipment. Examples of these include soft rolls, print heads, coater applicators and print blankets. Immediate detection, rejection and control of splices or joints create savings of up to tens of thousands of dollars per annum.Unaffected by printed surfaces, material color, grade changes and process speeds the Sentinel guarantees 100% reliable detection every day; every shift.
The Sentinel is a self-calibrating system that is powered by 24VDC. It provides an opto-isolated, digital electronic output with a pulse width selectable for 1, 10 or 100 milliseconds. The re-designed alarm indicators are low power, low voltage LEDs that are clearly visible to machine attendants. The unit can be mounted anywhere along the web at any angle and either right side up or upside down.The Sentinel can be connected directly to PLC control devices or interfaced into existing marking systems or directly control devices.
Modular in design, the new Sentinel requires 50% less energy to operate and can be equipped with auto tracking of the web edge eliminating operational intervention of deckle (web width) changes. The Return on Investment (ROI) is most often as little as 24 hours of operation.
