Steel Belt and Tracking 10: Edge Positioning ControlCase 1

EPC worked when belt width was 500mm and conveyor length was 3000mm. Temperature was from 20 to 300 degrees C. In general under these temperature there appear deformations and waves. These deformations hamper tracking by crown pulleys, while V-guides begin to deteriorate due to heat. However, this 500mm-wide belt rotated fine with EPC and we could obtain data as below that shows waves along belt width direction.

Steel Belt and Tracking 9: Air source of Edge Positioning Control

0.5MPa of air pressure is required in minimum, while during operation it uses only around 50 ml/min. On air supply we do give you advise. We recommend a handy compressor when you do not find air supply utility. Or employment of a booster or increase of bore diameter may be adequate when pressure is not prepared to the full extent.

Steel Belt and Tracking 8: EPC / Edge Positioning Control

Edge positioning is controlled by difference in pressure supplied to these 2 cylinders.
When the belt goes straight, supplied pressure is constant.
On the other hand when the belt leans to either right or left direction, air cylinder pressure on the leaned side is increased by control circuit, moving the belt to the opposite side.

Air cylinders are required to be heat-resistive, anticorrosive, and others, depending on operating conditions.

Steel Belt and Tracking 7. EPC / Edge Positioning Control

These are cylinders in EPC systems. In general they are available in the market, not special parts. 2 cylinders are required in one conveyor. They are placed on both sides of the driven pulley shaft to move the shaft on the length direction for adequate tension.

Steel Belt and Tracking 6. EPC / Edge Positioning Control

Our EPC, Edge Positioning Control targets wide conveyor belts under heat and hot dry air.

The whole system is as shown in the picture.
