Abstract
A method and unit for transversely cutting cigarette portions or similar on a filter assembly machine, whereby a cigarette portion is fed transversely through a cutting station to intercept a rotary circular blade, which is maintained in a work position by an arm mounted to oscillate about an axis parallel to the axis of rotation of the circular blade, so as to move the circular blade between the work position, a store for worn circular blades, and a store for new circular blades.
Claims21
A method of transversely cutting cigarette portions (2) on a filter assembly machine, the method comprising
- cutting a cigarette portion (2) by feeding the cigarette portion (2) transversely of its length through a cutting station to intercept a circular blade (8) rotating continuously about a first axis (9) parallel to length of the cigarette portion (2), the method being characterized by:
- supporting the circular blade (8) by an arm (13);
- moving the arm (13) between a work position, in which the circular blade (8) cuts the cigarette portions (2), an unloading position facing a first store (11) configured for storing a plurality of worn circular blades (8), and a feed position facing a second store (12) configured for storing a plurality of new circular blades (8);
- unloading the circular blade (8) from the arm (13) to the first store (11) at the unloading position by using the arm (13) to transfer the circular blade (8) from the arm (13) to the first store (11), and
- loading a new circular blade (8) from the second store (12) onto the arm (13) at the feed position by using the arm (13) to transfer the new circular blade (8) from the second store (12) onto the arm (13).
A unit for transversely cutting cigarette portions (2) on a filter assembly machine, the unit comprising
- a rotary circular blade (8) rotating continuously about a first axis (9) and located at a cutting station, and
- a conveyor (4) for positioning a cigarette portion (2) so that its length is parallel to the first axis (9) and for feeding the cigarette portion (2) transversely of its length through the cutting station to intercept the rotary circular blade (8),
- the unit being characterized by:
- a first store (11) configured for storing a plurality of worn circular blades (8);
- a second store (12) configured for storing a plurality of new circular blades (8);
- an arm (13) supporting the circular blade (8);
- and
- actuating means (45) for moving the arm (13) between a work position, in which the circular blade (8) cuts the cigarette portions (2), an unloading position facing the first store (11), in which the circular blade (8) is unloaded from the arm (13) to the first store, and a feed position facing the second store (12), in which a new circular blade (8) is loaded from the second store (12) onto the arm (13);
- wherein in the unloading position, the actuating means (45) further moves the arm (13) to transfer the circular blade (8) from the arm (13) to the first store (11), and in the feed position, the actuating means (45) further moves the arm (13) to transfer the new circular blade (8) from the second store (12) onto the arm (13).
