Sensor technology from LJU for position measuring

The widest variety of sensor systems which are firmly installed in the carriage convey the current status to the control system. The system uses these values to calculate the current position and speed in real time.

In this regard, LJU relies on state-of-the-art light curtains and scanner systems and has been nurturing development partnerships with notable manufacturers for years. Depending on the function task of the system and the operating environment encountered, the right solution is implemented by LJU in close cooperation with the customer.

Dual light curtain

  • Reads perforated strip along the travel path
  • As a reference for synchronised movements

Absolute position light curtain

  • Reads coded perforated strip along the travel path
  • For maintaining distance
  • Function trigger
  • Synchronous movement
  • Diagnostics

Barcode and data matrix code scanner

  • Reads barcode strip
  • Positioning and positioning reading in high-bay warehouses
  • Skillet
  • Overhead conveyors
  • Rotating assemblies and turntables

Track accessories from LJU for position measurement

Perforated strips or self-bonding barcode strips installed along the track form the counterpart to the sensor systems attached to the carriage. Accordingly, in interplay with the control system, position and speed are determined in real time so as to control the carriages within the system.

Depending on the function task of the system and the operating environment encountered, the right solution is implemented by LJU in close cooperation with the customer.

Perforated strip

  • For synchronous movement
  • With an equal split as a fixed digital reference

Absolute-coded perforated strip

  • For position detection
  • Coding for millimetre-precise positioning
  • Reading of system functions in conjunction with absolute value scanner

Bar code strip

  • Self-bonding and non-stretching strip
  • Barcode printed on strip every 3 cm
  • Current position determined using linear measurement sensor OLM-708

Control units from LJU for commissioning and maintenance

For the parameter assignment and maintenance of a system, the accessories should be both simple within the application and offer all necessary levels of freedom.

Accessories from LJU are based on many years of experience. We know on what this depends and enable the fitter and maintenance engineer to control the system safely, be that during setting up the system or during subsequent maintenance.

Parameter assignment and programming device (infrared)

  • Reading and interpreting of parameter sets, tables and other data
  • Setting of display modes
  • Reading of diagnostics data and version numbers
  • Transmission of firmware and user programs
  • Test functions and remote control option
  • Remote control function; e.g. manual positioning of the carriage

Remote control (infrared)

  • Remote control of various movement directions of the carriage
  • Very compact design

External modules from LJU

LJU offers additional modules for enhancing the capabilities of a system. For example, displays or infrared interfaces can be duplicated, which can be very helpful for maintenance personnel due to an installation situation. External address and data storage can also be configured to obtain unique vehicle identifiers in bus systems or to read out status information from an external box.

Vehicle address box

  • Unique vehicle identifier in bus systems
  • External box for installation on a vehicle

Vehicle address box with display and IR interface

  • Unique vehicle identifier in bus systems
  • External box for installation on a vehicle
  • Additional display for the visual reference of important information (e.g. vehicle status)
  • Additional infrared interface for remote control and parameter assignment

Customer-specific solutions

When no standard exists – Solutions for the most demanding requirements

To remain competitive in this day and age, ever greater demands are placed on automated production. In this respect, standardised products demonstrate their benefits, with their continuous production quality and market maturity. But sometimes "standard" will not do! Thanks to our in-house development department, we are able to design specific solutions which go well beyond the standard functionality. In this way, even the most difficult of tasks can be realised.
