摘要： Support structure for a transport unit of a planar motor to reduce or prevent transmission of force to an active surface of a stator. The transport unit is movable by at least one stator of the planar motor and a product is positionable on the transport unit. In at least one support position of the transport unit defined in relation to the support structure, the support structure applies at least one supporting force to the transport unit, while at least one process force, which acts on the product, is at least partially transmitted to the transport unit and counteracted. The transport unit is movable into and out of the support position in a floating manner via the at least one stator. The support structure is mounted on a base and at least partially diverts the counterforce caused by the supporting force to the base.

摘要： In order to specify a method for controlling a transport unit (TE) of a transport device (1) in the form of a long-stator linear motor, said method allowing safe transport of an object (O) without exposing the object (O) to critical movement limit values, the invention provides that a movement profile of the transport unit (TE) is established at least in sections along the transport path (2) depending on a relative movement profile of a relative point (PR) connected to the transport unit (TE) and spaced at a distance from a reference point (PT) of the transport unit (TE).

摘要： In order to improve the planning and implementation of the manufacture of a product in a manufacturing plant, the manufacturing plant is modeled via a machine network plan modeling the manufacturing plant as a network of manufacturing nodes, and the product to be manufactured being modeled via a product synthesis plan modeling the hierarchical structure of the product in the form of a tree of product synthesis nodes. The machine network plan and the product synthesis plan are linked with each other to form a manufacturing sequence, in which a manufacturing node of the machine network plan is selected for each operation node of the product synthesis plan, which selected manufacturing node carries out the manufacturing process to be carried out at the relevant operation node. The manufacturing sequence is carried out in the manufacturing plant via a system controller in order to produce the product.

摘要： In order to enable safe deceleration of a transport unit of a long-stator linear motor, wherein in a normal mode a plurality of drive coils of the long-stator linear motor are energized in such a way that a magnetic field coupled to a transport unit is moved along a direction of motion in order to move the transport unit along the direction of motion, according to the invention a switching to a controlled short-circuit mode is performed during the braking operation of the transport unit, in which at least some of the drive coils are short-circuited at least over a first time interval in said mode.

摘要： To correct aberrations in the image plane of a camera while modifying selected, modifiable camera settings that influence aberrations quickly and simply, a plurality of features with different known feature positions is provided in space. For each selected, modifiable camera setting influencing the aberration, at least two defined setting specifications are provided for modifying respective camera settings. For each setting specification, the camera captures the plurality of features. The camera determines positions of features in the image plane. Via a known mathematical method, a connection between different known feature positions in space and corresponding image positions in the image plane of the camera is determined. For each of the setting specifications of the selected modifiable camera settings, correction parameters of at least one mathematical correction model are determined for correcting the aberration. The at least one correction model is stored in the camera together with the determined correction parameters.

摘要： Method for transferring a transport unit of a long stator linear motor at a transfer position from a first transport section to a second transport section. On each side of the transport unit, excitation magnets are arranged to interact with driving coils, and on both sides of the transport unit, excitation-magnetic lateral forces are acting on the transport unit by an interaction of the excitation magnets with ferromagnetic components of the guide structure. Method includes supplying on at least one side of the transport unit a stator current n a driving coil to generate a lateral force-forming electromagnetic force that acts on the transport unit, so that a resulting lateral force, as a sum of the acting excitation-magnetic lateral force and of the lateral force-forming electromagnetic force, on each side of the transport unit is different to produce a steering effect on the transport unit at the transfer position.

摘要： Method for controlling a lifting device to move a load along a trajectory, to move the load in an efficient, automated, and collision-free manner between points, includes a start point and end point of the trajectory and prohibited zones are established which, during motion of the load are avoided. A computing unit calculates a geometric or rounded geometric or smooth geometric path, that kinematic and geometric limit values of the lifting device are predetermined, from which the computing unit, on the basis of the geometric or rounded geometric or smooth geometric path, calculates a dynamic or rounded dynamic or smooth dynamic path which provides time information about motion of the load along the geometric or rounded geometric or smooth geometric path. The geometric or rounded geometric or smooth geometric path and the dynamic or rounded dynamic or smooth dynamic path are combined for producing the trajectory.

摘要： In order to improve control of a long-stator linear motor, a first measured value is ascertained in a first measurement section and a second measured value is ascertained in a second measurement section, in each case along a transport path in a movement direction. The first measurement section overlaps, in the movement direction, the second measurement section in an overlap region, and the first measured value and the second measured value represent the same actual value of a physical quantity. An operating parameter of the long-stator linear motor determined based on a deviation occurring between the first measured value and the second measured value.

摘要： In order to carry out largely automated parameterisation of the closed-loop control parameters for closed-loop control of a hydraulic system comprising a servo drive, a method and a device for determining the closed-loop parameters of a closed-loop control unit of the hydraulic system are specified, wherein an actual system pressure of a hydraulic consumer of the hydraulic system is closed-loop controlled by means of a predefined set point rotational speed of a servo drive, wherein an actual rotational speed of the servo drive follows the predefined set point rotational speed, wherein an excitation signal is applied to the setpoint rotational speed, and the actual system pressure which is set here is measured, the dynamics of the hydraulic system are acquired from the actual rotational speed and/or the setpoint rotational speed and the actual system pressure, and the closed-loop control parameters are calculated from the acquired dynamics.
