摘要： An air stabilization system employing two parallel, opposite-facing Coanda nozzles, with each nozzle exhausting gas at opposite directions, subjects a moving flexible web to opposing forces effective to create local tension within the web. Each nozzle includes an elongated slot that is perpendicular to the path of the moving web. The nozzles serve as separate points along the machine direction for controlling the height of the web. The operative surface with the nozzles can exhibit a flush surface. The nozzles can be formed on elevated structures on the operative surface. The operative surface can be covered with a transparent substrate to minimize shape distortions on the moving web and to prevent debris from collecting around the sensor. By modulating the velocities of gases exiting the nozzles, the shape of the web can be manipulated to present a planar contour. The air stabilization system can be incorporated into a caliper scanner.

摘要： An air stabilization system employing two parallel, opposite facing Coanda nozzles, that are positioned adjacent a flexible moving web, with each nozzle exhausting gas at opposite directions, subjects the moving web to opposing forces effective to stabilize the web. Each nozzle includes an elongated slot that is parallel to the path of the moving web. The two Coanda nozzles serve as separate points along the machine direction for controlling the height of the moving web. By modulating the flow, pressure and other parameters of gases exiting the Coanda nozzles, the shape of the moving web between the nozzles can be manipulated to present a planar contour for measurements. The air stabilization system can be incorporated into a scanner head to measure the caliper of paper, plastic, and other flexible web products.

摘要： Paper and continuous web scanners operate at varying and high temperature conditions that cause distortion of the support beams and ultimately misalignment of the scanner heads. Circulating a heat transfer fluid between the support beams and through segmented fluid channels within the beam allows tuning of the beam's deflection when operating in an uneven thermal environment. The heat transfer rate can be modulated through various techniques, including: (1) varying the flow rate through each channel under manual or automatic control, (2) controlling the inlet fluid temperature of each channel with fluid immersion heaters or coolers, and (3) setting up the flow sequence via distribution channels that are, for example, in parallel, serial, or mixed.

摘要： Paper and continuous web scanners operate at varying and high temperature conditions. Regulating the temperature within the measurement gap between dual scanner heads during measurement and calibration modes of operation by employing air wipe and sheet guide temperature control assures consistent and accuracy sensor measurements of sheet characteristics. Air wipes blow pre-heated air into the measurement and the sheet guides are heated. The air temperature fluctuations that otherwise caused significant adverse effects on the sensors that measure, for example, the basis weight, ash content, and thickness of the moving sheet, are eliminated.

摘要： Numerous failure modes, causes, and adverse operating conditions on scanner systems exhibit mechanical signatures that are detected by three-axis accelerometers located in the upper and lower sensor heads. A diagnostic system for monitoring the scanning system that detects characteristics of sheet materials during linear translation along a translation axis of a bi-directionally driven mobile detector device includes a vibration sensor configured to measure vibrations generated by various components of the scanning system and to generate vibration signals indicative of operation conditions of the components. Correlating the vibration signals to modes of operations of the components identifies the source, location and severity of potential problems in the scanner. In dual scanning systems, the accelerometer in the upper scanner head monitors activities associated with movement of the upper carriage while the accelerometer in the lower scanner head monitors activities associated with movement of the lower carriage.

摘要： Upper to lower assembly analog position sensors in a dual scanning system measure alignment offsets. A controller uses error signals from the position sensors to calculate actuator error profiles that are used in the next scan in the same direction, with different error profiles being used for forward and reverse scans. Since the alignment error profiles are repeatable for a given set of scanner conditions, the actuator controller anticipates what the error signal will be before each scanning assembly reaches a given position. An optimized error correction can be calculated based on the error profiles and actuator bandwidth without concerns regarding feedback loop speed, overshoot, and unstable control oscillations. An actuation system driven from error profiles can correct for alignment offsets by actively changing belt tensions at the offsetting drive pulleys and/or changing the position of sensor assemblies relative to the drive belt systems.
