WEB GUIDE CONTROL SYSTEMS

34 Sensors? When detecting a wide width line or pattern edge, there is noneed to switch between the edge and line.? The change in output voltage for line (edge) deviation is notinfluenced by line width or color; therefore, once the gain ofthe controller is set during a trial run, it is not necessary toreadjust the gain.? During the interval when a line (edge) leaves the view fieldto when it returns, the position signal generated immediatelybefore the line (edge) leaves the view field is retained andoutput. Therefore, a follow-up operation can be performedwhen the meander speed of a web is fast and the line (edge)tends to be out of the view field.? Focus indicator lamps when the focal distance is correct andthe mounting interval between the path line and detector areappropriate.? When the edge (or edge of the line) to be detected is in thecenter of the field of view, the center indicator lamp lights.? When the device is connected to a controller that has anactuator lock contact input, (in cases of intermittent lines)the actuator is locked when the break in the line is detectedand follow-up operation is stopped until the next lineappears.Note: The position signal retention function is not available when an actuator locksignal output is used.Focus indicator lampThis lamp lights when the mountingdistance and angle between theLH110 and the web are correct andthe head is focused.Center indicator lampThis lamp lights when the edge ofthe web or edge of the line is in thecenter of the field of view of theLH110.Field of view switch(2.5 / 5 / 10 mm)This switch can changethe field of view (detectionrange).Light power switch(Blue / blue-red / red)This switch can change theemitted light color.Light color layout switchSelect which edge of the line todetect by switching the contrastbetween the web material andthe line.Line Follower Head LH110Optically detects register lines or patterns printed on the web and on the edge of the web.LPC or EPC systems can be created by combining the LH10 and a Liteguide Controller.Light emission distance 1 mm (from the scattering plate)Detection view field 2.5 / 5 / 10 mm (switch between these)Light source High luminance LED (2 colors: blue and red)Output volatagePositionsignal0 to +5 V DC (high),0 to +0.5 V DC (low)Actuatorlock signalOpen collector 30 V, 0.1 A orless ON without line (edge)Resolution 14 μmDetection element CCD linear image sensorPower supply +15 V DC, 300 mA / -15 V DC, 50 mAAmbient temperature 0 to +50?CAmbient humidity 35-85% RH (no condensation)Protective structure rating IP50Body material AC4CMass Head: 0.6 kg (including the cable)Screw guider: 0.5 kgUser-friendly display and functionsLine Follower Head LH19The Line Follower Head LH19 is a sensor which opticallydetects the meandering of register lines or patterns printed onwebs or the edges of webs. This meander sensor can be usedsafely for a long time because it uses an SPD as the sensingelement and a white LED as the light source.Sensor gap 10 mmRange of measurement 5 to 3 mm (spot diameter)Register line width 1.0 mm or moreLight source White LEDLight source wavelength Visible lightSensitivity 0.1 mm of displacement of webOutput voltage 0 to 5V DCDetection element SPDPower supply ±15V DCAmbient temperature 0 to +50?CAmbient humidity 35-85% RH (no condensation)Protective structure rating IP50Body material Cast aluminum alloyMass Head: 450 g Cable: 250 g? With an SPD, response speed is increased and sensing accuracyduring high-speed operation is improved.? Spot diameter can be adjusted easily with the slide control withoutchanging the sensing distance.? A white LED is used as the light source, which secures long andstable operation and reduces the spare parts cost.
