Roller conveyor to arrive at the pinch-roll of the winding reel of a hot strip rolling train

摘要

Roller conveyor to arrive at the pinch-roll or other downstream usage device for feeding strip or wide flat products (13) in a hot strip rolling train, the roller conveyor comprising a plurality of parallel and substantially horizontal cylindrical rollers (14) having their axes perpendicular to the longitudinal axis of feed of the strip (13), the roller conveyor cooperating with at least one transversely movable guiding sidewall (17) having an inner surface cooperating with a lateral edge of the strip (13), at least each of the rollers (14) positioned immediately upstream of the downstream usage device consisting of two coaxial half-rollers, which are respectively a first half-roller (14a) and second half-roller (14b), at least the first half-roller (14a) being associated with the at least one guiding sidewall (17), the half- rollers (14a, 14b) being associated with independent respective motors (15a, 15b) governed by a control and actuation unit (16) which actuates the motors (15a, 15b) at least momentarily at different speeds, the control and actuation unit (16) being associated with monitoring devices (18) cooperating with the inner surface of the sidewall (17) and monitoring a condition of contact between the lateral edge of the strip (13) and the inner surface of the sidewall (17).
