Overview

This analog tension controller was designed for easy-to-use, safe control and ease of operation. This intuitive controller, with its simple functionality, is easy for anyone to use.

Feature

• Excellent Responsiveness via Constant Loop Gain Circuit
  The control circuit uses Proportional + Integral calculation, providing fast response and high accuracy. Additionally indexed calculation is used to maintain a constant loop gain, regardless of changes in diameter. This maintains high responsiveness without hunting, maintaining appropriate loop gain at all times.
• Easy to Use and Operate
  The unit can be controlled automatically as long as you have an automatic machine contact. Consequently, the controller is easy for anyone to use, as long as a tension value is set. When stopped, a sequence allows the stopped output value corresponding to the diameter to be obtained.
• Tension Display
  It is possible to find the total tension, as well as the tension on just one side. Select an analog or digital display to suit your preferences.
• Wide Range of Applications
  Fits the final control elements of a large number of applications, including air brakes/clutches, air motors, electro-magnetic brakes/clutches, torque motors, and magnetic coupling motors. Select the installation method to suit the location, from panel-mounted, stand-alone, or mounted.
• Connection with a wide range of tension sensors
  Can be connected to the following wide range of Nireco sensors: MB, MG, MC, CD, MJ, CJ, TSA, and intrinsically safe TSA sensors
• CE Compliant
  CE marking compliant product

LINE FOLLOWER HEAD LH500

Overview　|　 Feature　|　 Application　|　 Specifications

Overview

Line Follower Head LH500 is a sensor that optically detects register lines or patterns printed on a web and, in combination with a controller (*1), can be used to form an EPC (Edge Position Control) and LFC (Line Follower Control) system.

Line Follower Head LH500 stores detected lines as image information, which it uses to perform pattern matching and comparison operations on image information during operation. With this new system, even if register lines and printing accessories are mixed, the stored lines are always tracked.

*1 Liteguide controller AE1000/AE900L, Web Guide amplifier EH321A

Feature

• Printed lines stored as image information
The new system is highly effective and keeps track of stored line information, even if register lines and printing accessories are mixed.
• Automatic optimization of illuminant color and light volume completed simply by pressing the search button
The sensor has an automatic light adjustment function which can be used also for highly reflective material, such as aluminum foil and copper foil.
• Central positioning simple with laser pointer
The device is equipped with a laser pointer, improving visibility of control position.
• LED bar makes detection status easy to see
The detected object and detection status can be seen at a glance. Use the search button to toggle between operating mode (deviation display) and search mode (pattern display).

Application

This is an example of using a combination of LH500 and a Liteguide controller with a slitter machine. The register lines or patterns printed on a web are detected using LH500. Then, so that the line always passes through the reference position, the unwinding reel shifts in the opposite direction from the deviation to cancel out irregularity, stretching, shrinking, uneven thickness, etc., of the web, enabling high accuracy slitting.

Bộ chỉnh biên LH110 - Nireco Vietnam - TMP Vietnam

LINE FOLLOWER HEAD LH110

Overview　|　 Feature　|　 Specifications　|　

Overview

The LH110 can be used on slitting machines as the sensor to optically detect register lines or patterns printed on the web. In combination with an amplifier (Liteguide Controller AE1000, AE900L or Webguide Amplifier EH321A), the LH110 can form an EPC (Edge Position Control) and LFC (Line Follower Control) system.

Feature

Easy to understand display and functions

• No edge/line changeover required
When detecting a wide width line or pattern edge, there is no need to switch between the edge and line.
• Polarity switching not required
When the gradation of the web material and line, (or that of the left and right edges) is reversed, there is no need to switch control output polarity.
• Gain readjustment not required
The change in output voltage for line (edge) deviation is not influenced by line width or color; therefore, once the gain of the controller is set during a trial run, it is not necessary to readjust the gain.
• Position signal retention function
During the interval when a line (edge) leaves the view field to when it returns, the position signal generated immediately before the line (edge) leaves the view field is retained and output. Therefore, a follow-up operation can be performed when the meander speed of a web is fast and the line (edge) tends to be out of the view field.
• LED indication of optimum attachment position of detector
An LED indicator lights when the focal distance is correct and the mounting interval between the path line and detector are appropriate.
• Line (edge) position indicated by LED
Integral action is the standard control operation; however, when used in combination with a position transmitter, the LH110 is capable of proportion action and integral + proportional action. You can choose the best control action for the machine that you are using.
• An LED indicator lights when the detected edge is at the center of the view field.
When the device is connected to a controller that has an actuator lock contact input, (in cases of intermittent lines) the actuator is locked when the break in the line is detected and follow-up operation is stopped until the next line appears. Note: The position signal retention function is not available when an actuator lock signal output is used.
