A machine for filling and closing containers comprises: a conveyor, step-activated in an advancement direction, laterally provided with a plurality of gripping devices which grip containers at an active branch of the conveyor. A filling station has a plurality of nozzles for filling the containers, and weighing devices for detecting a correct filling of the containers. A closing station has capping devices for closing the filled containers with caps, and sensors to detect correct closure. A release station, located downstream of the closing station has manipulators which are either de-activated to allow transit of incorrectly filled and/or closed containers, which are released onto a reject conveyor downstream and in line with the active branch; or activated transversally to the advancement direction to collect correctly filled and closed containers and release them onto an outlet conveyor, adjacent and parallel to the reject conveyor.

What is claimed is: 1. A machine for filling and closing containers comprising: a first conveyor, activated in a variable operating step, for moving a plurality of containers in an advancement direction, towards a gripping station; a second conveyor, located downstream of the first conveyor, step-activated in phase with the first conveyor and ring-wound in a substantially horizontal plane and laterally provided with a plurality of gripping and supporting devices able to receive, at the gripping station, containers released by the first conveyor; the second conveyor having an active branch in which the containers supported by the gripping devices are arranged in line with the first conveyor, the containers moved in the same advancement direction, the active branch with said containers being subjected to a main gas flow, substantially vertically directed, of a sterile substance; a filling station, located along the active branch and downstream of the gripping station, the filling station having a plurality of nozzles operated for batched filling of the containers located at said filling station with a product, and weighing devices which detect a correct filling of the containers; a closing station, located along the active branch and downstream of the filling station, the closing station having capping devices operated to pick up caps from a store, bring the caps in proximity of opening mouths of the containers, and to press-insert the caps in the mouths to close the containers; and sensors for detecting correct closure of the containers by the capping devices; a release station, located along the active branch and downstream of the closing station, the release station having manipulator devices responsive to at least signals coming from the weighing devices and the sensors, the manipulator devices being either deactivated to allow transit of incorrectly filled or incorrectly closed containers a reject conveyor located downstream of and in line with the active branch of the second conveyor receiving said incorrectly filled or closed containers; or activated to operate in a transversal direction with respect to the advancement direction, to pick up correctly filled or closed containers from the active branch, an outlet conveyor, located adjacent and parallel to the reject conveyor, receiving the correctly filled or closed containers picked up by the manipulator devices. 2. The machine of claim 1, further comprising a sampling conveyor, located adjacent and parallel to the reject conveyor and the outlet conveyor, for receiving samples of containers picked up from the active branch by said manipulator devices. 3. The machine of claim 2, further comprising a first sterilizing station, located along the active branch between the gripping station and the filling station, a first supplementary gas flow, substantially directed vertically, of an inert sterile substance being directed towards empty containers borne on the active branch in said first sterilizing station. 4. The machine of claim 2, characterized in that the outlet conveyor is interposed between the reject conveyor and the sampling conveyor. 5. The machine of claim 4, further comprising a storage station, associated to the outlet conveyor, the storage station receiving collecting crates, containers picked up from the active branch by the manipulator devices being disposed in the collecting crates. 6. The machine of claim 2, characterized in that the sampling conveyor is interposed between the reject conveyor and the outlet conveyor. 7. The machine of claim 6, further comprising a storage station, associated to the outlet conveyor, the storage station receiving collecting crates, containers picked up from the active branch by the manipulator devices being disposed in the collecting crates. 8. The machine of claim 1, further comprising a first sterilizing station, located along the active branch between the gripping station and the filling station, a first supplementary gas flow, substantially directed vertically, of an inert sterile substance being directed towards empty containers borne on the active branch in said first sterilizinci station. 9. The machine of claim 8, wherein the first sterilizing station has a plurality of nozzles which dispense the first supplementary gas flow. 10. The machine of claim 8, further comprising a second sterilizing station, located along the active branch between the filling station and the closing station, a second supplementary gas flow, substantially vertically directed, of an inert sterile substance being directed towards filled containers borne on the active branch, before closure thereof, in said second sterilizing station. 11. The machine of claim 10, wherein the second sterilizing station has a plurality of nozzles which dispense the second supplementary gas flow. 12. The machine of claim 1, characterized in that the store is subjected to the main gas flow of the sterile substance.
