Patent ID: 8037993

Claim:
Container carrier turning device for a specimen container provided with an identifying barcode and inserted into a carrier made advancing by a conveyor belt, comprising carrier stopping means for rotatably engaging a lateral surface of said carrier to stop the advancing movement of the carrier while leaving it free to rotate around the container axis, carrier pressing means for rotatably engaging an upper surface of said carrier, elastic means for forcing said carrier pressing means to a carrier engaging position, first pneumatic means for moving said carrier stopping means to a carrier stopping position and second pneumatic means for moving said carrier pressing means to a carrier disengaging position against the action of said elastic means, characterized in that said elastic means includes an elastic plate fixed at one end to a supporting frame and supporting a pressing bearing, said pressing bearing being selectively movable with respect to said frame by a pneumatic piston directly actuating a deformation of the elastic plate, between a raised deformed position in which the pressing bearing is not in contact with the upper surface of the carrier, and a lower position in which the pressing bearing rotatably engages the upper surface of the carrier pushing the carrier towards the conveyor belt providing the rotation of the carrier, an idle rotatable bearing being provided opposite to the pressing bearing to facilitate the carrier rotation when the elastic means applies its force to the upper part of the carrier.
