Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a head for applying a threaded cap to a container. More specifically, the present invention relates to a head comprising a hollow support, a member for holding the cap, and a magnetic clutch disposed between the support and the member for holding the cap. • [Prior Art] This type of head is used in an automated machine to close the container. The support body is fixed to the bottom end of the mandrel having a rotational motion and a translational motion such that, in use, the component for applying the cap member has a rotational motion. SUMMARY OF THE INVENTION It is an object of the present invention to provide a head for applying a cap that would be more economical than a known type of head. According to the invention, the object is achieved by a head for applying a cap having the features forming the subject matter of claim 1 of the patent application. [Embodiment] Referring to the drawings, reference numeral 1 is a head for applying a threaded cap to a container. The head 10 includes a hollow support body 12 having a threaded bore 14 through which the hollow body 12 is directly secured to the bottom end of the mandrel 16. The mandrel 16 forms part of the machine from 201016558 for applying the threaded cap to the container. In operation, the mandrel 16 has a rotational motion about the longitudinal axis 18 and a translational movement along the same longitudinal axis 18. The rotational motion and the translational motion are coordinated to obtain the helical motion of the mandrel 16. The manner in which the rotational-translational motion of the mandrel 16 is produced is conventional and is outside the scope of the present invention. The support body 12 has a cavity 2〇 in which the rotary bushing 22 is accommodated. The rotary bushing 22 is supported by the support body 12 through the rolling bearing 24, and

The rotary bushing 22 is axially fixed with respect to the support body 12. The rotary bushing 22 has a prismatic guide aligned with the longitudinal axis 18. In the illustrated (four), the prismatic guide is formed by an axial cavity 26 of the bushing 22 having a channel profile 28. The head 1 includes a magnetic clutch 3〇 including two magnetic ring members 32, 34 that are disposed to face each other and are coaxial with respect to each other. ^The first magnetic ring member 32 is fixed to the engagement with the external thread 38 of the support body 12. The ring nut 36 ρ second magnetic ring member 34 is directly fixed to the rotary bushing n. In the unintended example, the second magnetic ring member 34 is fixed to the radial flange 4〇 of the rotary bushing 22 by the screw M2. The adjustment ring nut % is movable in the direction of the longitudinal axis 18 when it is rotated relative to the support body 12. The movement along the axial direction of the adjustment ring nut 36 enables the axial width of the J-capillary bearing 44 between the two magnetic ring members 32, 34 to be adjusted. The main adjustment makes it possible to adjust the sliding torque of the magnetic separation from the A and the 口3. The Λi ring/nut 36 is attached to the support body 12 by means of a radial screw. Companion (4) 卽 position upset 201016558 The head ίο also includes a member for gripping the cap member 50 that receives the prismatic guide 26 of the rotating bushing 22, 2 for the holding cap member = the member includes along the longitudinal axis, The wire 18 is elongated by the shaft 52. The shaft 52 includes a bottom portion 54 and a top portion 56 that are passed to each other by respective threaded extensions 57. It is contemplated that the axial screw 58 provides a safety mechanism for unscrewing between the prevention portion 56. The top portion 56* has a sliding engagement with the rotary bushing 22_profile 28 _ turn in the longitudinal direction. The shaft 5" is rotatably and axially movable with respect to the rotary bushing 22. The head (10) is fixed to the top end of the portion 56 to prevent the shaft 52 (four) from being detached downwardly from the bushing n. The coil spring 62 is opposite to the shaft 52 Shaftly disposed, and tending to push down the first end of the shaft spring 62 against the bottom front end of the rotating bushing 22. The opposite end of the spring 62 rests against the pump 52 52 reversible spring 62 acts against the rotating bushing 22 is displaced upward. The applicator member 64 is secured to the bottom end of the shaft 52 so as to receive and retain, to be applied. The applicator member 64 supports the outer portion of the design of the "elastic ring 68 radial-tone" inwardly from the base of the armor member (the second member) of the arm member 64 is supported inwardly from the outer portion of the base member 66. Ball 70. The applicator member 64 includes a slidably engaged applicator extractor 72. The extractor 72 and the right/orward groove 74 are configured to be ejected from the base crotch to be designed for discharge due to lack of container and may not be applied to the capacity 201016558 The cap of the device. In operation, the head 10 is secured along the axis 18 on the bottom end of the helix, which will center the head onto the head 10. In the first step #11 υ perform the cap member, for example , 底座 The base 66° of the applicator element 64 is limited to the interference of the cap inserting micro when the base 66/light is light, the ejector 72 is displaced upwards. The mesh is present in the base 76 as follows: In the step of the thread, the threaded member that keeps the cap in the bottom of the container against the T-piece of the T-piece. (4) 1G spiral motion: Cap: Screw onto the container. Magnetic clutch 3. It is determined that the maximum helical twist = sex ... '34 is rotationally fixed relative to each other until the torque is 1 if the torque is less than the calibrated twist of the magnetic clutch 3g. The torque on the shaft 52 exceeds the calibration value and the magnetic ring members 32, 34 slide (s) against each other to prevent the torque transmitted to the shaft 52 from being higher than the value of the setting. During application of the cap, _52 can be moved upward relative to the rotating bushing 从而 to squeeze the bobbin 62. During the swirling motion, the elastic force exerts an axial force on the cap member. The shaft 52 is sufficiently long to allow axial movement of the length l of the shaft 52 relative to the flange 78. The flange 78 has a forked base 80 through which the shaft 52 extends. The ejector 72 of the applicator member 64 engages the bottom surface ' of the flange 78 to discharge the cap member. The flange 78 # is fixed to the rotating conveyor supporting the mandrel and has a base 8 for each head 1 . In the absence of the container, the cap remains within the base 66 of the applicator member 64. Any cap that may remain in the base 66 is removed by the protrusion 201016558 edge: the pusher element 76 that is pushed downward. This solution is simple and reliable' and it is known that automatic removal of any cap members that may have been retained in the applicator member 64 prevents the need to inspect the applicator member 64 for a cap. Figure 3 illustrates a variation of the head 1 according to the present invention. Elements corresponding to those described above are denoted by the same reference numerals.

A threaded extension is formed on the shaft 52 to which the ring nut 86 is engaged, and the ring nut acts as a seat for the bottom end of the spring 62. The ring nut is axially displaceable relative to the shaft 52 to change the preload of the spring 62. A radial screw 88' can be provided to prevent the ring nut 86 from shifting. In this variation, the top end of the spring 62 abuts against the support 9 应用于 applied to the bottom end of the bushing 22. The head 1 according to the present invention is more compact and less expensive than a head having a magnetic clutch of a known type. In particular, the fact that the rotary bushing 22 and the shaft 52 that is rotationally fixed and axially movable relative to the bushing 22 are envisaged makes it possible to reduce the radial dimension of the support member 12.
