摘要:
An operating wheel of a packing machine (1), having an annular drum (3); a number of through pockets (8) carried by the annular drum (3) and each for receiving a relative product (21); first drive means (18) for rotating the annular drum (3) in steps to feed the pockets (8) along an annular path (P) extending through a loading station (23) and an unloading station (25); first and second push means (53, 44) for engaging respective pockets (8) at the loading station (23) and the unloading station (25) respectively; second electric drive means (56, 47) for imparting to the push means (53, 44) respective substantially radial reciprocating movements to and from respective withdrawn rest positions inside the annular drum (3) and through the respective pockets (8); a first safety device (58) for preventing the annular drum (3) from rotating when at least one of the push means (53, 44) engages a respective pocket (8); and a second safety device (59; 80) for preventing the push means (53, 44) from moving from the respective withdrawn positions when the annular drum (3) is rotating.
摘要:
A variable-capacity store (1) having an endless belt conveyor (5), in turn having a conveying branch (8) and a return branch (11); an adjusting assembly (12) for adjusting the lengths of the conveying branch (8) and the return branch (11) in complementary manner; and at least one actuating device (37;38) for transmitting a force to the belt conveyor (5) to move the belt conveyor (5), and having a limiting device for limiting the maximum value of the force transmitted to the belt conveyor (5) using a maximum threshold value established as a function of the fill level of the store (1).
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 and machine (1) for packing a group (2) of cartons of cigarettes using a flat tubular package (3), whereby a top wall (4) of the flat tubular package (3) is engaged by suction by a gripping head (10), which is then moved to feed the flat tubular package (3) to a seat (11) which engages a bottom wall (5) of the flat tubular package (3) by suction; a relative rotation movement is then produced between the seat (11) and the gripping head (10) to convert the tubular package (3) from the flat configuration to an open configuration; the group (2) of cartons of cigarettes is pushed inside the open tubular package (3); the gripping head (10) releases the top wall (4) of the open tubular package (3); and the seat (11) is moved to feed the tubular package (3) to a closing station (28) where the tubular package (3) is closed.
摘要:
A cigarette packing machine (1) wherein an output wheel (3) advances a number of gripping heads (6; 54, 55), each for receiving, at an input station (8), a respective packet (7) with its longitudinal axis (10) crosswise to the traveling direction (22) of the gripping heads (6; 54, 55), and with outer longitudinal tabs (17) open, detached from respective inner longitudinal tabs (16), and supported on respective folding wings (36) carried by the relative gripping head (6; 54, 55); the output wheel (3) feeds the packet (7) through a gumming station (48), where gum (18) is applied between each outer longitudinal tab (17) and the relative inner longitudinal tab (16), and moves the relative folding wings (36) to fold each outer longitudinal tab (17) into a closed position contacting the relative inner longitudinal tab (16) before the closed packet (7) is fed to an output station (9).
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).
