Abstract

A laboratory sample distribution system comprising a transport plane and a cleaning device for cleaning the transport plane is presented. The cleaning device is adapted to automatically clean the transport plane similar to sample container carriers moving also on the transport plane. A laboratory automation system comprising such a laboratory sample distribution system is also presented.

Claims

1. A laboratory sample distribution system, the laboratory sample distribution system comprising:

a plurality of sample container carriers configured to carry one or more sample containers;

a control device;

a cleaning device, wherein the cleaning device comprises a container for storing cleaning fluid and a valve arranged below the container, wherein the valve is connected to the container and an outlet opening, wherein the valve comprises a receiver in wireless communication with the control device to receive signals from the control device to open or close the valve, and wherein the control device sends a signal to the receiver to open the valve and dispose cleaning fluid;

a transport surface configured to support the sample container carriers and the cleaning device, wherein the cleaning device comprises a cleaner configured for cleaning the transport surface; and

a driver configured to move the sample container carriers and the cleaning device on top of the transport surface, wherein the driver comprises electromagnetic actuators located below the transport surface, and wherein the sample container carriers and the cleaning device each comprise a magnetically active device for interaction with a magnetic field generated by the electromagnetic actuators such that a magnetic drive force is applied to the sample container carriers and the cleaning device;

the control device is configured to control the movement of the sample container carriers and to control the movement of the cleaning device on top of the transport surface by activating the electromagnetic actuators of driving the driver to generate the magnetic drive force such that the sample container carriers move along corresponding transport paths and that the cleaning device moves along a cleaning path, and such that the transport paths of the sample container carriers have priority over the transport path of the cleaning device.

2. The laboratory sample distribution system according to claim 1, wherein the cleaner comprise a cleaning cloth.

3. The laboratory sample distribution system according to claim 2, wherein the cleaning cloth is a microfiber cleaning cloth.

4. The laboratory sample distribution system according to claim 1, wherein the cleaning device comprises a container for storing a cleaning fluid and a disposer for disposing the cleaning fluid over the transport surface.

5. The laboratory sample distribution system according to claim 1, wherein the cleaning device and the sample container carriers have identical horizontal cross sections.
