摘要:
To pack a group (3) of cigarettes (2) in a rigid packet, a collar (6), a respective inner sheet (4) of wrapping material and a respective group (3) of cigarettes (2) are fed successively into a same conveying seat (25) in which the collar (6) and the inner sheet (4) are at least partly folded together about the group (3) of cigarettes (2) as of respective flat initial configurations.
摘要:
A method of transferring articles (3), in particular, packets of cigarettes, whereby each article (3) is transferred from a first seat (8) on a first wheel (2) to a second seat (9) on a second wheel (5), and whereby the two wheels (2, 5) rotate in opposite directions about respective axes (7, 5a) parallel to each other; during transfer, the two seats (8, 9) are maintained aligned with each other in a direction (D) which varies, during transfer, by oscillating about an intermediate direction (48) perpendicular to the two axes (7, 5a).
摘要:
A method and device (1) for applying a label (2) to a packet (3) of cigarettes travelling in a given direction (D1) along a conveying path (P1); to apply the label (2) to the packet (3), a pickup head (33) is fed along a feed path (P2) by rotating the pickup head (33) about two axes (29, 31) parallel to each other, and by moving the pickup head (33) radially with respect to one of the two axes (31).
摘要:
A method of transferring wrappings (2), wherein each wrapping (2) is defined by a sheet of wrapping material (5) and has at least one flat wall (6), provides for feeding a wrapping (2) along a curved path (P) by means of a pocket (19) of a conveyor (17); for guiding the wrapping (2) along the curved path (P) by means of a guide (28; 59) contacting the wrapping (2); and for moving a plate (30, 31, 32; 60) of the guide (28; 59) with respect to the pocket (19), so that a flat face (38, 45, 46; 62) of the plate (30, 31, 32; 60) is maintained contacting the entire flat wall (6) of the wrapping (2) along a portion of the curved path (P).
摘要:
A method and machine for packing a product (5) - in the example shown, a group of cigarettes - in a blank (3) of packing material, whereby the blank (3) is fed to a first seat (10) on a packing conveyor (7), the product (5) is fed to a second seat (11) on the same packing conveyor (7), and a relative movement is imparted to the two seats (10, 11) to form, in one of the two seats (10, 11), a blank-product assembly (48).
摘要:
A packing machine (52) provided with a wrapping conveyor (64; 69) moving along a wrapping path and having a plurality of recesses (65; 71) each of which is designed to receive a respective article (54) together with a respective wrapping sheet (2); and with a plurality of folding stations successively arranged along the wrapping path, each folding station comprising folding units (66; 72) arranged to cooperate with the wrapping sheets (2) to fold the same around respective articles (54); the folding unit (66; 72) in at least one of the folding station has a folding device (1) presenting a fixed block (4) and a movable block (6) defining respective contiguous flat surfaces (5, 7) blending along a fold line (3); the movable block (6) is activated by an articulated parallelogram actuating device (8) having two connecting rods (20, 21) connected by cranks (22, 23) hinged to the fixed block (4) to rotate, with respect to the fixed block (4), about respective axes (42, 43) parallel to the fold line (3); the movable block (6) being hinged to the two connecting rods (20, 21), and defining a further crank rotating, with respect to the fixed block (4), about an axis (11) coincident with the fold line (3).
摘要:
A method of overwrapping packets (2) in the form of a rectangular prism, whereby a packet (2), as it is fed continuously along a wrapping path (P), is first centered with respect to a relative conveying seat (45), and is then paired with a relative sheet (13) of wrapping material, which is folded about the packet (2) to form a tubular wrapping (16) projecting axially from the packet (2) in the form of two tubular appendixes (19), which are folded to form a closed overwrapping (107); each tubular appendix (19) being at least partly folded onto the relative packet (2) before the relative tubular wrapping (16) is completed.
