Specimen container carrier for conveyor in laboratory automation system
View Patent ↗A specimen container carrier for a conveyor in a laboratory automation system which includes a circular body driven by the conveyor and container holding elements arranged in the circular body, the container holding elements being maintained in a container holding position by respective elastic elements and are connected to each other by synchronization elements forcing the specimen container to remain coaxially positioned with respect to the circular body.
1. A specimen container carrier for engaging a container on a conveyor in a laboratory automation system, comprising:
a base circular body having a plurality of pivoting holes, a plurality of spring coupling pintles, and a pin;
a closure member having a plurality of pivoting holes, wherein the base circular body and the closure member are attached to form a cavity;
a plurality of centering fingers, each finger including at least one tooth, a lower pivoting hinge operatively engaging the pivoting hole of the base circular body, and an upper pivoting hinge operatively engaging the pivoting hole of the closure member, and a spring coupling pintle, the fingers vertically extending over the base circular body;
a circular rotor provided with a plurality of slits and a rotor cavity rotatably mounted on the pin of the base circular body such that the circular rotor is disposed within the cavity; and
a plurality of springs, each spring elastically connecting one of the plurality of fingers with the base circular body by coupling each base circular body pintle and the finger pintle, in order to provide an inward rotation of the fingers along the lower and upper hinges so that the container is grasped by the fingers,
wherein the at least one tooth of the finger rotatably engages with the slit of the circular rotor in order to synchronize and balance the inward force of each finger, providing a centering action on the container.
2. The specimen container carrier according to claim 1 , wherein the pin of the base circular body has a cavity in which a tag transponder is housed for identification of the specimen container carrier.
