A braking and/or clamping device for a shaft guided in relation to a basic body, includes an actuating assembly (10) and a shaft-coupling assembly (80). The actuating assembly comprises a split housing (11) which has two bending plates (15, 16) which can bulge elastically in certain regions. The bending plates each have gripper jaws (23, 24) with frictional surfaces (31, 32). A sealed pressure chamber (37), which can be filled with a pressure medium, is situated between the bending plates. Parts of a shaft-coupling assembly project between the clamping zones, said parts establishing and establish the linking to the braked or clamped shaft. When the pressure in the pressure chamber is relieved, the frictional surfaces of the actuating assembly can be applied to the frictional surfaces of the shaft-coupling assembly, thereby providing the braking and/or clamping force.

To provide a rotary table device that can prevent the occurrence of malfunction before it happens. A rotary table device equipped with both or one of a clamping mechanism and purge mechanism which operate by way of working fluid, the rotary table device including: a detection unit that detects a pressure or flow rate of the working fluid; a transition information storage unit that acquires and stores transition information related to transition of a pressure value or flow rate value of the working fluid detected by the detection unit; a judgment value storage unit that stores in advance a plurality of sets of judgment value information related to judgment values for judging a pressure value or flow rate value of the working fluid; and a notification unit that notifies of notification information according to the pressure value or flow rate value of the working fluid, based on the transition information stored in the transition information storage unit and the plurality of sets of judgment value information stored in the judgment value storage unit.

A direct-drive two-axis machining head includes a head-drive unit and a shaft-drive unit. The head-drive unit includes a head-installing interface, a first motor, an axis-A supporter, and a first braking module mounted at an outermost rim of either a first motor seat or a stator of the first motor for braking the axis-A supporter. The shaft-drive unit further includes an axis-A-installing interface, a second motor, a shaft connector, and a second braking module mounted at an outermost rim of a second motor seat of the second motor for braking the shaft connector. The head-drive unit further includes a towline fixation sheet metal and a towline pipeline shield. The towline fixation sheet metal connects the rotor seat. One end of the towline pipeline shield connects the towline fixation sheet metal, while another end thereof connects the head-installing interface so as to shield a plurality of pipelines.

The invention relates to a transport device for transporting objects from work station to work station A, B, C, D of a production facility, to a production facility for producing products, comprising a transport device of this type, in particular to a production facility for producing containers filled with a medical product, and to a method for transporting objects from work station to work station of a production facility. The transport device has an object carrier 3 on which a plurality of object carrier elements 6 are arranged for placing down one or more objects, and a drive unit 5 for driving the object carrier. The object carrier 3 can be moved in successive cycles in such a way that the object carrier elements 6 can be transported on a movement path 8 from work station to work station A, B, C, D. The transport device is characterised in that at least one object carrier element 6 on the object carrier 3 is arranged to be displaceable relative to the object carrier in the direction of the movement path 8 on which the object carrier elements can be transported from work station to work station. In addition, the transport device is characterised in that a dog element 10 and a retaining element 14 are assigned to the object carrier element 6. Depending on the actuation of the dog element and the retaining element, either the carrier element in question is carried along by the object carrier and moved from work station to work station or the carrier element remains at a work station. As a result, the object carrier can move in order to transport objects to a work station that has a short process time whilst an object carrier element remains at a work station having a long process time.

In a method of controlling a rotary table device, a clamp mechanism drive unit is controlled to unclamp a brake disk. Thereafter, a pressure of working fluid supplied to an unclamp fluid chamber is decreased, and a motor drive unit is controlled to rotate a motor. Then, the abrasion quantity of the piston and the clamp member is calculated based on a reference pressure and a pressure when the load torque of a spindle exceeded a reference load torque.
