To allow a movement limit or a dimension of a mover to be changed safely in a transport system in the form of a long-stator linear motor during operation of the transport system, a method provided that, during operation of the transport system, a new movement limit or a new dimension is predetermined for a first transport unit, and it is checked whether the new movement limit or the new dimension results in a risk of collision with another, adjacent transport unit or a barrier of the transport system due to the predetermined collision logic, and, if no risk of collision is recognized, the new movement limit is used in the collision logic as a collision movement limit for the first transport unit or the new dimension is used in the collision logic as a collision dimension of the first transport unit.

Transport system and method for operating a transport system with collision monitoring

In order to specify a method for controlling a transport unit (TE) of a transport device () 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 () depending on a relative movement profile of a relative point (P) connected to the transport unit (TE) and spaced at a distance from a reference point (P) of the transport unit (TE).

Method for controlling a transport unit of a transport device in the form of a long-stator linear motor

A transport system in the form of a long-stator linear motor and method for operating a transport system in the form of a long-stator linear motor including a stator on which a plurality of magnetic-field-generating units is arranged and a plurality of transport units which are moved along the stator simultaneously. In an event of a system error in a part of the transport system, the method includes defining an error area on the stator that includes only a part of the stator with a defective part of the transport system, and transferring the magnetic-field-generating units within the defined error area to a specified error state.

Method for operating a transport system in the form of a long-stator linear motor

In order to easily prevent a collision of transport units, which are moved along a conveyor line of a long stator linear motor, it is provided that a minimum distance to be maintained between the two transport units is changed as a function of the position of the two transport units along the conveyor line.

Method for operating a long stator linear motor with transport units and collision monitoring

To safely avoid a collision of two transport units in the switch area during operation of a conveyor in the form of a long stator linear motor with a switch, a collision zone is provided in the switch area, wherein the collision zone extends from the beginning of the switch in each case a length on the respective conveyor section, and to define the collision zone, the transport units are considered as two-dimensional objects and a position of the first transport unit on the first conveyor section is determined, which the first transport unit is allowed to occupy, so that the second transport unit can be moved as a two-dimensional object along the second conveyor section without collision through the switch and a distance between this first position and the beginning of the switch is determined and at least this distance is used as the first length.
