Laboratory sample distribution system and laboratory automation system
A laboratory sample distribution system is presented. The system comprises sample container carriers carrying a sample container and comprising a magnetically active device. The system also comprises a transport plane supporting the sample container carriers and comprises drive modules comprising first line shaped conductors extending in a first direction and arranged parallel to each other and second line shaped conductors extending in a second direction and arranged parallel to each other. The system comprises a driver electrically connected to each of the first and second conductors of the drive modules. The driver selectively applies a drive current and/or voltage to the first and second conductors such that a conductor current results in the conductors driven by the drive current and/or voltage. The conductor current selectively causes a drive force to the sample container carriers such that the sample container carriers move along individual transport paths on the transport plane.
1. A laboratory sample distribution system, the laboratory sample distribution system comprising:
a number of sample container carriers, wherein the sample container carriers each comprise at least one magnetically active device and wherein the sample container carriers are adapted to carry at least one sample container;
a transport plane, wherein the transport plane is adapted to support the sample container carriers;
a number of drive modules, wherein each of the drive modules comprises,
a number of first line shaped conductors, wherein the first conductors extend in a first direction and wherein the first conductors are arranged parallel to each other, and
a number of second line shaped conductors, wherein the second conductors extend in a second direction and wherein the second conductors are arranged parallel to each other; and
a driver, wherein the driver is electrically connected to the first and second conductors of the drive modules, wherein the driver is adapted to selectively apply a drive current and/or a drive voltage to one or more of the first and second conductors such that a conductor current results in the one or more conductors driven by the drive current and/or the drive voltage, wherein the conductor current selectively causes a drive force to one or more of the sample container carriers such that the sample container carriers move along individual transport paths on the transport plane.
