摘要:
A machine for applying inland revenue stamps (2) to packets (3) of cigarettes, the machine having a conveying device (10) for feeding the packets (3) along a given path (P1) through an application station (11); and a feed device (24) for feeding the stamps (2) to the application station (11), and applying each stamp (2) to a given portion of a respective packet (3); the feed device (24) being movable crosswise to the travelling direction (A) to adjust the given portion of the packet (3) to which the stamp (2) is applied, and comprising a gumming device (13) located along the given path (P1), upstread from the application station (11), to apply adhesive to the given portion of the container (3)
摘要:
A method and device for feeding a continuous strip (2) of packing material and a tear-off ribbon (3) to a user machine (4), and whereby the continuous strip (2) and the tear-off ribbon (3) are unwound simultaneously off respective reels (7, 13) and fed along respective paths (6, 12) and at the same speed through a joining station (23), where the continuous strip (2) and the tear-off ribbon (3) are joined to each other to form a composite strip (25) of packing material, which is fed to the user machine (4) via a traction assembly (35) which exerts a first pulling force (F1) on the continuous strip (2) and the tear-off ribbon (3); a further traction assembly (28, 29) engaging a portion (36) of the tear-off ribbon (3) extending between the relative reel (13) and the joining station (23), to exert on the portion (36) a second pulling force (F2) in the same direction as the first (F1).
摘要:
A method and unit for closing the ends of tubular wrappings (5) on a cigarette packing machine (1), wherein the tubular wrappings (5) enclosing respective groups (3) of cigarettes are fed continuously and successively along an annular path (P) and through two folding stations (21, 24), in the first of which a movable folding member (37) and a fixed folding member (42), common to all the tubular wrappings (5), fold the short sides (9) of a projecting tubular portion (8) of the tubular wrapping (5) to define two projecting major tabs (22), and in the second of which a single rocker arm (46), common to all the tubular wrappings (5), is swung to successively fold the two major tabs (22).
摘要:
A unit (23; 23') for rejecting products (9), each fed along a given path (P) inside a respective pocket or seat (11) of a conveyor (10), has a pneumatic actuator (26; 26') located along the path (P) of the products (9) to exert, on each product (9) for rejection, a pneumatic force to expel the product (9) from the respective pocket or seat (11) in time with the passage, or during a stop, of the pocket or seat in front of the pneumatic actuator (26; 26').
摘要:
A method and unit (3) for changing the configuration of an automatic machine (1), whereby a user selects a desired end configuration (C2) by means of a selection device (6), and a display device (5) then displays an orderly list (11) of all and only the operations to be performed on the machine (1) to convert the machine (1) from a current start configuration (C1) to the desired end configuration (C2); the list (14) is arranged according to the sequence in which the operations are performed, and for each operation are displayed the state (16) of at least one respective operating value (VF) in the start configuration (C1), and the state (17) of the same operating value (VF) in the end configuration (C2).
