Abstract
In order to provide a transport device having a planar motor, which gives greater flexibility in the movement of the transport units, at least one multiple-action transport unit is provided on the transport device. On the multiple-action transport unit, at least first drive magnets for electromagnetic interaction with the drive coils of a first planar motor and at least second drive magnets for electromagnetic interaction with the drive coils of a second planar motor are provided. The multiple-action transport unit can be moved two-dimensionally on the transport plane of one of the planar motors, or can be moved simultaneously, unidimensionally on neighboring transport planes of the first and second planar motor.

A transport device comprising at least two planar motors, each of which forms a transport plane in which at least one transport unit can be moved two-dimensionally, wherein the transport planes of the at least two planar motors are adjacent to one another and are inclined with respect to one another at a contact angle, which is 90°, with drive coils being provided on each planar motor in order to interact electromagnetically with drive magnets of a transport unit in order to move the transport unit (3) in the relevant transport plane, characterized in that wherein at least one multiple-action transport unit is provided on the transport device, wherein on the multiple-action transport unit at least first drive magnets are provided in order to interact electromagnetically with the drive coils of a first planar motor, and at least second drive magnets are provided in order to interact electromagnetically with the drive coils of a second planar motor, wherein in the transport device at least one further planar motor is provided which forms a transport plane which is directly adjacent to the transport plane of the first planar motor and is normal with respect thereto, wherein drive coils are provided on the at least one further planar motor in order to interact electromagnetically with drive magnets of a drive unit in order to move the transport unit in the relevant transport plane, and that the at least one multiple-action transport unit can be moved two-dimensionally in the transport plane of one of the planar motors or can be moved one-dimensionally in the adjacent transport planes of at least two planar motors at the same time, wherein the at least one multiple-action transport unit can be moved from the transport plane of the second planar motor via the transport plane of the first planar motor into the transport plane of the at least one further planar motor.
A method for operating a transport device comprising at least two planar motors with transport planes that are adjacent to one another and are inclined at a contact angle of 90° relative to one another, wherein drive coils provided on the planar motors are controlled by at least one planar motor control unit, wherein at least one multiple-action transport unit is provided on the transport device, wherein on the multiple-action transport unit at least first drive magnets are provided in order to interact electromagnetically with the drive coils of a first planar motor, and at least second drive magnets are provided in order to interact electromagnetically with the drive coils of a second planar motor, wherein in the transport device at least one further planar motor is provided which forms a transport plane which is directly adjacent to the transport plane of the first planar motor and is normal with respect thereto, wherein drive coils provided on the at least one further planar motor can be controlled by a planar motor control unit, and that the at least one multiple-action transport unit is moved two-dimensionally in the transport plane of one of the planar motors or is moved one-dimensionally in the adjacent transport planes of the at least two planar motors at the same time, by controlling the drive coils of at least one of the planar motors by the corresponding planar motor control unit in order to interact with the first or second drive magnet of the multiple-action transport unit to generate a propulsive force.
