<p>The equipment for stacking and removing of objects, especially flat plates, includes a pivot arm rotating more than 180 deg. about a horizontal axis. Two pivoting arms are rotatably mounted in the machine frame and driven by a shaft with a grab. At the free end of Bach pivoting arm (10, 11) is rotatably mounted a shaft (13, 14) which supports a steering lever (15, 16) carrying the grap equipment (17, 18, 19). The shaft (13, 14) is driven by one chain sprocket (22, 23) which is connected by a chain (28, 29) to another chain sprocket (20, 21) rigidly mounted on the machine frame (1). The grab is provided with a lateral bar (17) which is rotatably mounted in the steering levers (15, 16). Rigidly attached to the lateral rod (17) are two chain sprockets (26, 27) which are connected by chains (31, 39) with chain sprockets (24, 25) of the shafts (13, 14). The sprockets act together so that a plate carried by the grabs (18) is always in a horizontal position.</p> |
