Abstract
The invention relates to a rotatable gripper device (1) for picking up and rotating products which are supplied on a conveyor belt. The device according to the invention comprises a gripper head (2, 3) which can rotate about a vertical central shaft (4) and has a gripping member (18) which can rotate about its axis. For upward and downward movement, the device comprises a first cam roller (6, 7) and cam discs (8), and for rotation about the axis comprises a second cam roller (9, 10) and cam disc (11). The device according to the invention is of a simple and relatively lightweight design, so that it is suitable for operating at high speeds. The gripper device according to the invention can be used to accurately set the rotational path of the gripping member (18) at the gripping position and the release position, by means of the shape of the cam disc, in order to produce a gradual transfer. A large number of rotational patterns can be obtained by rotation of the gripper heads along a vacuum distributor plate with two or more vacuum ports.
