IMPROVED APPARATUS FOR HANDLING METAL SHEETS AND OPERATION METHOD THEREOF

摘要

An apparatus for handling sheets and an operating method thereof are disclosed. The apparatus includes: a handling unit (3) for gripping and transferring sheets (2) to and from a sheet change support (1) with a substantially horizontal attitude; and a receiving-transmitting electromagnetic beam unit which generates electromagnetic beams arranged on a plane which is intercepted by the sheets (2) when they take up an attitude at least partially different from the horizontal sheet. The receiving-transmitting electromagnetic beam unit is fixedly arranged on at least a couple of linear bars (B1, B2) arranged at the same height for generating a horizontal-mesh barrier, consisting of intersecting stationary electromagnetic beams, generated by the receiving-transmitting unit, and the barrier being defined above an area occupied by the sheet change support. The present invention provides a simple and economic solution to the problem of detecting anomalies in the operating steps of picking-up and transferring the metal sheets onboard the handling devices.
