Manipulator for the transfer of bobbins

The manipulator for the transfer of bobbins has a carriage (1) which is horizontally displaceable on a monorail (3) by means of transport rollers (5) and supporting rollers (6, 7). For this purpose, two of the transport rollers (5) are connected to a first electric motor (4). The carriage (1) has a carrier plate (8), on which is held via an axial bearing (9) and a nut (10) a column (11) which has two longitudinal grooves and a rest (12), parallel to it, with circuit breakers (13). Seated on the nut (10) is a gearwheel (14) which is in engagement with a strip (15) connected to a pneumatic cylinder (16). Seated on the gearwheel (14) is the mounting of an electric motor (17), the shaft of which is connected to a screw (18), on which a running nut (19) is displaceable in the column (11). The running nut (19) is connected via guides (20) in the longitudinal grooves of the column (11) to a guide sleeve (21) which itself carries, via a sliding bearing (22), an arm (23), to which is fixed a rod (25) which carries a tappet (28) and a blocking mechanism for the bobbin (26).
