摘要:
A rigid carton type wrapper (1; 80; 86) for packets (2) of cigarettes is fashioned as a box-like container (8) with a hinged lid (10) erected from a flat blank (42; 81; 99) presenting a main portion (43), and an appendage (44) extending from the main portion (43) parallel with a longitudinal axis (L') of the blank; the appendage (44), which appears U-shaped and functions as a frame (27) projecting from an open end (9) of the container (8), is folded double into contact with the main portion (43) to bring the frame (27) into position relative to container (8). The wrapper (1; 80; 86) appears essentially as a rectangular parallelepiped with a predominating longitudinal axis (L), having a front face (24) and a rear face (25) disposed parallel one with another, a top end face (19) and a bottom end face (15), and two flank faces (26) lying mutually parallel and at right angles to the front and rear faces (24, 25); the front, rear and flank faces (24, 25, 26) are joined one to another by way of slender fillets or bands (38, 39, 40, 41) extending parallel to the longitudinal axis (L).
摘要:
A supply unit (2) and a user unit (4) employed in the manufacture of tobacco products, typically cigarettes (3) and the like, are linked by a duct (5) along which a mass (6) of the cigarettes is advanced from the outfeed of the supply unit (2) toward the infeed of the user unit (4). The advancing mass (6) of cigarettes is parted at an intermediate zone (18) of the duct (5) either by rods (62) or by rods (62) or by a pair of frames (68), in such a way as to create a void that will accommodate a trolley (28) directed into the duct (5) from a housing (27) by an elevator (59); once inside the duct (5), the trolley (28) proceeds to push the mass (6) of cigarettes (3) from the intermediate zone (18) toward the inlet (12) of a hopper (13) in such a way as to empty the duct (5) completely, for example when changing over from one brand of cigarette (3) to another. To advantage, the trolley (28) is composed of two articulated structures (29) so that its geometry and dimensions can be varied to match the variations in geometry and depth of the duct (5).
摘要:
A flat blank (1; 25) for the formation of a rigid carton (2; 26) having the shape of a parallelepiped, in which two panels (5', 8') form a front wall (5) and, respectively, a lid (8) on the carton (2; 26), and in which the panel (5') which forms the front wall (5) is divided by a pre-weakened tear line (10) into a first and a second portion (11', 12'); and the panel (8') which forms the lid (8) is divided by a fold line (13; 29) into a first and second portion (14', 27'; 15', 28'), the first portion (14', 27') being adjacent to the panel (5') that forms the front wall (5).
摘要:
Wrapping material (2) utilized by a packaging machine (1) is advanced along a set feed path (3) through a station where an accessory material (12), typically adhesive, is applied in spots (13) to selected areas of the surface (9), whereupon the material (2) is charged electrostatically at a first station, and thereafter sensed at a second station to reveal the distribution of the charges; the electrostatic charges register more strongly on and around the spots (13), so that by measuring any variation in strength relative to the remainder of the surface, identifiable with faulty application of the adhesive, substandard material (2) can be detected before it reaches the wrapping stations of the machine.
摘要:
A pack for tobacco products consists in at least one rigid packet (2) appearing as a container (3) presenting a bottom end face (4), surmounted by a hinged lid (5) presenting a top end face (6) and rotatable between a position in which the packet is open, and a position of interaction with an inner frame (9) anchored to the container (3), in which the packet is closed. The packet (2) presents at least two main faces of which a first face (14) appears flat and a second face (15) is composed of a substantially central flat portion (16) and two curved portions (17) by which the flat portion (16) is connected to the longitudinal edges (18) of the flat first face (14), so that when viewed in cross-section the packet (2) presents a substantially semicircular shape, or that of a rounded isosceles trapezium.
摘要:
Wrapping material (2) supplied to a packaging machine is caused to advance along a predetermined feed path (3) through a first checking station (27a) where an emitter device (29) charges at least one predetermined portion (30, 34) of the wrapping material (2) electrostatically, and a second checking station (27b) where a sensor (31) detects the presence of the electrostatic charges appleid previously to the predetermined portion (30, 34) of the material (2). The sensor (31) is positioned along the feed path (3) downstream of and at a predetermined distance from the emitter device (29).
