Carousel for processing containers

1. A carousel for processing containers comprising a base structure that can rotate about the rotation axis of said carousel and supports a plurality of supporting elements that are mutually angularly spaced apart and are intended to support a respective container to be processed, said base structure being associated with at least one device for detecting the orientation of the containers carried by said supporting elements, said detection device comprising at least one sensor that can move about the rotation axis of said carousel between an initial angular position and a final angular position and vice versa, during movement from said initial angular position to said final angular position said at least one sensor being functionally associated with a container that moves about the rotation axis of said carousel and about a longitudinal axis thereof that is parallel to said rotation axis, in order to detect a feature of said container, wherein the carousel comprises kinematic connection means arranged between said base structure and said at least one sensor, which are adapted to couple integrally in rotation said at least one sensor and said base structure during the movement of said at least one sensor between said initial angular position and said final angular position, said kinematic connection means being associated with motor means adapted to return on command said at least one sensor from said final angular position to said initial angular position by way of an angular movement of said at least one sensor in the opposite direction with respect to the rotation of said base structure about the rotation axis of said carousel.

2. The carousel according to claim 1 , wherein said motor means are supported by said base structure and rotate integrally with said base structure about said rotation axis.

3. The carousel according to claim 1 , wherein said at least one sensor is supported by a supporting element that has at least one first portion that can rotate with respect to said base structure about the rotation axis of said carousel, said kinematic connection means comprising an element for kinematic connection between said first portion of said supporting element that is extended around the rotation axis of said carousel and an actuation body that is supported by said base structure.

4. The carousel according to claim 3 , wherein said kinematic connection element is adapted to render rotationally integral said first portion of the supporting element at the same angular speed as said base structure during the movement of said at least one sensor from said initial angular position to said final angular position.

5. The carousel according to claim 3 , wherein said actuation body can be actuated by said motor means in order to move said first portion of said supporting element in rotation in the opposite direction with respect to the rotation of said base structure about the rotation axis of said carousel in order to allow the passage of said sensor from said final angular position to said initial angular position.

6. The carousel according to claim 3 , wherein said actuation body comprises an output shaft of an actuation motor that is supported by said base structure.

7. The carousel according to claim 6 , further comprising a pinion element with an axis that is parallel to the rotation axis of the carousel and is connected in input to said output shaft and in output to a gearwheel extended around said rotation axis of the carousel and defining said at least one first portion.

8. The carousel according to claim 6 , wherein said kinematic connection element comprises said pinion.

9. The carousel according to claim 3 , wherein said kinematic connection element comprises a closed annular body.

10. The carousel according to claim 9 , wherein said closed annular body comprises a toothed belt for connection between said pinion and said gearwheel.
