Szalag pozicionáló technológia

FUNCTION 

Web guidance 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 position control with conveyor belts.

APPLICATION

With belt position control of conveyor belts, the pivoting roller is mounted on the bottom run just ahead of the lock roller. The actuator must be arranged parallel to the belt direction of movement, whereby the actuating movement must be at the angle bisector between the infeed and outfeed path. Note that the infeed length should be at least one belt width, and the outfeed length should be kept as short as possible. The wrapping around the positioning roller should be between 40° and 60°. If the production speed is > 1000 m/min, then the wrapping should be reduced to 10° to 20°. Exact position measurement is performed using an edge sensor, which is attached immediately after the positioning roller. To prevent possible interference from the stretch roller on the belt control system, this roller is only allowed to be positioned with its axis parallel.
