A structure of a solenoid of a claw includes a solenoid tube, which is provided with multiple coils that are arranged circumferentially on an outside surface at intervals. The coils have one end connected with a control switch and an opposite connected with a power supply source. A vertical tube is disposed in the solenoid tube and is provided therein with multiple magnetic elements to respectively correspond to the coils. A bottom of the vertical tube is pivotally connected to fingers of the claw. The control switch includes a chip electrically connection with multiple control elements that are connected to the coils respectively. A temperature switch is arranged on a wall of the solenoid tube to detect a temperature thereof. The temperature switch is electrically connected to the control switch. The power supply source is connected to the coils, the control switch, and the temperature switch.

A gripper mechanism includes a stator and a pair of mobile grippers moveably coupled to the stator via a linear bearing, the stator comprising a housing and a permanent magnet mounted within the housing, the mobile gripper comprising a support portion, a coil mounted on the support portion, and a gripper finger coupled to the support portion. The gripper mechanism further includes at least one magnetic locking mechanism comprising at least a first permanent magnet mounted on one of the stator and the mobile grippers, and a complementary soft magnetic material portion or magnet mounted on the other of the stator and the mobile grippers.

Various embodiments relate to magnetically moveable displacement devices or robotic devices. Particular embodiments provide systems and corresponding methods for magnetically moving multiple movable robots relative to one or more working surfaces of respective one or more work bodies, and for moving robots between the one or more work bodies via transfer devices. Robots can carry one or more objects among different locations, manipulate carried objects, and/or interact with their surroundings for particular functionality including but not limited to assembly, packaging, inspection, 3D printing, test, laboratory automation, etc. A mechanical link may be mounted on planar motion units such as said robots.

A gripper arm for a gripping device for gripping, holding and guiding in particular bottle-like containers which includes a base body and a gripping section arranged on the base body, wherein the gripping section is pivotably mounted about a pivot axis in and against a direction of pivoting. At least one limiting means for limiting a pivoting range of the gripping section and at least one resetting means is provided for returning the pivoted gripping section into a vertical position. Further provided are a gripping device as well as a transport device.

A container transport arrangement is used to transport containers, such as beverage bottles or similar containers, which container transport arrangement has adjustable container transport devices.

The present invention relates to a gripping apparatus (100) for gripping objects, comprising a sleeve-like main body (200), a permanent magnet (210) accommodated in the main body (200), and an armature element (220) which is arranged coaxially with the permanent magnet (210) and is designed to be movable between a first position close to the permanent magnet and a second position remote from the permanent magnet, wherein: the sleeve-like main body (200) comprises at least two gripping fingers (230) which are each designed to be connected to the armature element (220) by means of an actuating bar (240), and the gripping fingers (230) are moved towards one another when the armature element (220) is moved into the first position, and moved away from each other to a release position when the armature element (220) is moved into the second position; and the gripping apparatus (100) comprises a switchable coil (300) which, when in the switched state, is designed to generate a magnetic field that opposes the permanent magnet (210).

A gripping apparatus which has a base body (5) and a plurality of gripping arms (18) arranged on the base body (5) so as to be distributed about a center axis (4). The gripping arms (18) can be driven to carry out a gripping arm pivoting movement (22) in order to grip or release an object. All of the gripping arms (18) are integrated into a gripping unit (11) which is separate from the base body (5) and which has a fastening sleeve (15) to which the gripping arms (18) are fastened and which is axially placed on the base body (5) by means of a sleeve-shaped fastening portion (62), assuming a usage position. The gripping unit (11) is detachably fixed in the usage position by means of a securing device (78).

The present invention will provide a device in which the gripping action is achieved by a compliant membrane manipulated by electromagnetic forces. The gripping force provided by the present invention is best suited for delicate objects, as it gently applies the gripping force necessary for displacement. This is accomplished through a chamber, a membrane, a plunger attached to the membrane, and a solenoid configured to manipulate the plunger, and thus, the membrane.
