In the area of the facility where glass panels are staged, a servodriven actuator system identifies and tracks the leading edge of the glass as it moves along the facility’s conveyor line. After the conveyor apparatus picks up the glass, it is unable to compensate for the non-standard height of the pallets used to transport and
store the glass panels in a horizontal position.

Task
Leading manufacturers of insulating glass units require a sensor solution that monitors and precisely adjusts glass panel positioning on a production conveyor belt, based on the exact height of non-standard pallets. These pallets are used to transport and store glass panels horizontally.
Solution
- Dimetix Laser Distance Sensors offer several methods of communicating to
control systems commonly used in manufacturing and production
applications. - In the area of the facility where glass panels are staged, a servodriven actuator system identifies and tracks the leading edge of the glass as it moves along the facility’s conveyor line. After the conveyor apparatus picks up the glass, it is unable to compensate for the non-standard height of the pallets used to transport and
store the glass panels in a horizontal position. - Dimetix Laser Distance Sensor measure the height of the pallet and adjust a position to stop the glass panel. After the panel is halted, the machine begins tilting it onto the pallet precisely at the point where there is no chance the glass can slide or be misplaced. It is then gently placed on the pallets next to other glass panels.

Challenge
- The increasing flexibility of production lines requires a high adaptability of sensors. Continually changing object geometries, different temperatures and very high radiation or surrounding temperatures are no rarity.
- In a pilger mill those rough conditions can be found, among others in the production of seemless steel pipes. The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C.
- After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter.

Solution
- The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19.
- The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase.
- An optimum adaptation to the operating conditions is given due to the adjustable response temperature. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions.
- The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C.
- Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling.
