Belt position control systems Erhardt-leimer – Đại lý Erhardt-leimer Vietnam

FUNCTION

Rollers that are at an angle to the direction of belt travel cause the belt to move laterally. This principle is used by the pivoting roller systems ELBANDER for belt control. The pivot point for the pivoting roller is one of the two bearings at the ends. The positioning roller is positioned at an angle around this point depending on the correction required.

AREA OF USE

Pivoting roller systems are primarily used for belt control with conveyor belts.

APPLICATION

On conveyor belts, the pivoting roller is mounted on the bottom run just ahead of the lock roller. The actuator is to be arranged at an angle of 15° to the direction of travel of the belt. The actuating movement must be at the angle bisector between the infeed and outfeed path. The infeed path should be at least one belt width. The outfeed path is to be kept as short as possible. The wrapping around the positioning roller should be between 40° and 60°. For production speeds >1000 m/min, the wrapping should be reduced to 10 – 20°. The position is measured using an edge sensor immediately before the positioning roller. To prevent possible interference from the stretch roller on the web control system, this roller is only allowed to be positioned with its axis parallel.
