A feeding unit to feed a component in an automatic manufacturing machine; has: at least one holding head designed to receive and hold the component; a closed curved guide arranged in a fixed position along an application path; an equipment supporting the holding head and provided with at least one slide coupled to the guide by a plurality of wheels; a linear electric motor, and a movable slider electro-magnetically coupled to the stator and is rigidly connected to the slide. The guide has, on the surface in contact with the wheels, a first transverse profile having a concavity or a convexity; the wheels have, on the surface in contact with the guide, a second transverse profile, which has a convexity or a concavity, and generates, with the first profile, a shape coupling between the guide and the wheels, which forbids a transverse movement of the slide relative to the guide.

Unit to feed components in an automatic manufacturing machine

A feeding unit to feed components in an automatic manufacturing machine; the feeding unit has: a plurality of sucking holding heads, which are each designed to receive and hold a corresponding component; a closed curved guide, which is arranged in a fixed position along the application path; a plurality of equipment, each supporting a corresponding holding head and provided with at least one slide, which is coupled to the guide so as to freely slide along the guide by a plurality of wheels; a suction chamber, which is mounted so as to rotate around a rotation axis; and a flexible connection system, which pneumatically connects the suction chamber to each holding head.

Unit to feed suction-held components in an automatic manufacturing machine

A feeding unit to feed a component in an automatic manufacturing machine, which has at least one holding head designed to receive and hold the component; a conveyor to cyclically move the holding head along an application path; and a rotation station arranged along the feeding path and in which the holding head rotates relative to the equipment and around a rotation axis to vary the orientation of the component. The conveyor has a closed curve guide arranged in a fixed position along the application path; and an equipment supporting the holding head and provided with at least one slide coupled to the guide so as to freely slide along the guide. An actuation system controls rotation of the holding head around the first rotation axis and has a cam and a cam follower roller, which can be coupled to the cam and mechanically connected to the holding head.

A feeding unit for feeding a component of a hygiene absorbent article; the feeding unit has: at least one sucking-holding head, which is designed to receive and hold the component; a conveyor to cyclically move the holding head along an annular application path; an input station in which the holding head receives a corresponding component which is connected&#x2014;without gaps&#x2014;to a continuous web; a cutting station provided with a cutting device, which cuts the continuous web crosswise; and an output station in which the holding head releases the component; the conveyor has: an annular guide; a slide which supports the holding head and is coupled to the guide so as to freely slide along the guide itself; and a linear electric motor, which has a stator, which is arranged in a fixed position along the guide and a mobile slider which is electro-magnetically coupled to the stator so as to receive, from the stator, a driving force and is rigidly connected to the slide.
