1. Machine for applying threaded caps to containers, comprising:
- a holding device configured for holding a respective container, the respective container having an external thread;
at least one screwing head including a gripping member, the grippinq member configured for holding a respective cap, the respective cap having an inner thread;
at least one electric motor associated with the at least one screwing head and configured to control a rotational movement of the gripping member about a longitudinal axis of the gripping member, wherein the gripping member performs a translational movement along the longitudinal axis synchronized with the rotational movement so that during operation, the gripping member moves along a screwing path;
at least one vision system configured for detecting images of the external thread of the respective container and of the inner thread of the respective cap held by the gripping member, the at least one vision system comprising;
a first vision device, wherein the first device detects images of the external thread of the respective container; and
a second vision device, wherein the second vision device detects images of the inner thread of the respective cap; and
an electronic control unit configured to process the images of the external thread and inner thread and to determine an angular position of a start point of the external thread of the respective container and an angular position of a start point of the inner thread of the respective cap and for controlling an adjustment of angular position of the respective cap so as to carry out screwing of the cap onto the respective container with the respective inner thread arranged in a preset relative position.

6. A machine for applying threaded caps to containers, comprising
a central column rotatable about a longitudinal axis; -
a turret coupled to and rotationally fixed with respect to the central column, comprising at least one guide having a fork element at one end of the guide, wherein the fork element receives a neck of a container; at least one screwing head disposed above the at least one guide, the at least one screwing head comprising; a spindle having a seat disposed at one end of the spindle, wherein the seat receives a cap and wherein the spindle is movable parallel to the longitudinal axis; and a motor coupled to the spindle, wherein the motor rotates the spindle with respect to the turret; at least one vision system fixed relative to the central column, comprising; a first vision device, wherein the first vision device records images of a thread of the container; and a second vision device, wherein the second vision device records images of an inner thread of the cap; an electronic control unit configured to receive the images of the thread of the container and of the inner thread of the cap, recorded by the at least one vision system, wherein the electronic control unit processes the images of the thread of the container and of the inner thread of the cap and wherein the electronic control unit determines an angular position of a start point of the thread of the container and an angular position of a start point of the inner thread of the cap, the electronic control unit being configured to control an adjustment of an angular position of the cap relative to the container, so as to carry out screwing of the cap onto the container. - View Dependent Claims (7, 8, 9, 10)
