This is achieved in that an interface (31) is provided between a free end (10) of the robot arm (5) at the end and the gripping and/or holding device (6), which interface (31) is bridged by a coupler (25) fixed in a non-rotating arrangement to the robot arm (5) and by a flange (11) adapted thereto, which flange (11) is connected in a non-rotating arrangement to the gripping and/or holding device (6) and the drive shaft (24), in that a first inductively operated transceiver (12) is provided in the coupler (25), which transceiver (12) is connected to a power source (15) via an electrical line (14) fed to the robot arm (5), in that a second inductively operated transceiver (13) is provided in the flange (11), which is connected to the electric motor (9) in the gripping and/or holding device (6) via electrical lines (14), and in that an air gap (21) is provided between the coupler (25) and the flange (11) as a component of the interface (31).

An example device may include a rounded outer incline ramp and a rounded inner incline ramp surrounding a central axis. The rounded inner incline ramp and the rounded outer incline ramp may be inversely aligned relative to the central axis. The device may also include a piston carrier oriented in a direction parallel to the central axis. The piston carrier may include a first piston including a first roller positioned on the two ramps at a first point, where the first piston is configured to act on the two ramps in a direction parallel to the central axis. The piston carrier may also include a second piston including a second roller positioned on the two ramps at a second point opposite the first point, where the second piston is configured to act on the two ramps in a direction parallel to the central axis.

A gripper assembly for gripping a portion of a container may include a spindle configured to rotate about a vertical axis. The assembly may also include an actuating plate disposed on or about the spindle. The actuating plate may be configured to actuate toward a central shaft in response to a force applied to a first cam follower. The assembly may also include a gripper configured to at least one of open and close in response to the actuating plate being actuated toward the central shaft and a locking cam configured to contact the first cam follower and in at least one position to limit movement of the actuating plate toward the central shaft.
