System for conveying supports for containers for biological liquid samples, and automatic analysis system comprising such a conveying system

A conveying system configured to convey containers supports intended to support containers containing samples of a biological liquid, the conveying system including at least:

• a first support guide element defining a first guide track and a second support guide element defining a second guide track, the first support guide element being configured to receive a containers support and guide said containers support in translation along the first guide track, the second support guide element being configured to receive a containers support and guide said containers support in translation along the second guide track,
• a self-propelled conveying carriage displaceable along a conveying track extending along the first and second support guide elements, the first and second support guide elements being disposed on either side of the conveying track, the self-propelled conveying carriage comprising a drive element movably mounted between a first drive position in which the drive element is configured to transmit a drive movement to a containers support received on the first support guide element, a second drive position in which the drive element is configured to transmit a drive movement to a containers support received on the second support guide element, and a release position in which the drive element is configured to release the containers supports, the self-propelled conveying carriage being configured to displace the containers support in translation along the first guide track when the drive element is in the first drive position and the self-propelled conveying carriage is displaced along the conveying track.
