摘要:
Loss of tobacco from the ends of cigarettes is reduced or prevented by applying foamed adhesive thereto. The foam may in general be blown onto the cigarette ends [(FIGS. 1, 2 and 4)] or may be "printed" onto the cigarette ends [(FIG. 3 and FIGS. 5 and 6)]. The expansion ratio of the foam in preferably at least 10:1, so that very little liquid adhesive is needed to contact a significant area of tobacco. Thus the liquid content of the adhesive may be readily absorbed into the tobacco so as not to create a drying problem. In a preferred example [(FIG. 1)] foam is supplied by a pipe [24] to fill apertures on a disc [20] from which measured quantities of foam are blown by an air jet from a pipe [28.] Suction is applied to the filter ends [108]of the cigarettes via a manifold [18] and flexible seals [12C] to help in drawing the foam into the cigarettes.

摘要:
A method and apparatus for packing batches of cigarettes, in which batches B are transferred from a hopper 10 into compression boxes 16 of an intermittent conveyor 14, and are then packaged (e.g. in soft packs) while passing along continuous conveyors 22, 30 and 38. Compressed batches B are transferred into U-shaped foil wrappers F1 in compartments 28 of the conveyor 22, when folding flaps 88 fold over the two sides of the wrapper before the transfer is completed (FIG. 4). In a modification, the batches are formed from a continuous stream of cigarettes (FIGS. 8 and 9), and any voids V in the stream are filled by an intermittent acceleration rotor 350 (FIG. 11).

Filter cigarettes are produced by uniting tobacco sections (12, 122) and filter portions (21, 120) with a wrapper (28, 124) which carries a relatively thick circumferential bead (126) of adhesive or other filler material to provide an effective seal around the cigarette. The cigarettes may be assembled on parallel assembly lines (16, 18) supplied with tobacco sections from a common maker line (10) by a carrier conveyor (14) arranged to supply alternate sections to different assembly lines disposed at 90.degree. to the maker line.
摘要:
Successive rows of cigarettes delivered axially from a packing machine hopper outlet (12) are engaged by a cyclically-movable transfer member (24, 32, 425) which accelerates each row sideways and closes up spaces between cigarettes (C) before transferring the row to a conveyor (22) moving continuously at machine speed. The conveyor may be a drum (22) which transfers the cigarettes to a pocket conveyor (62) in which the cigarette bundles are formed, or it may be the pocket conveyor itself. The hopper may have several spaced outlets (12) so that rows may be supplied to the pocket conveyor (62) at spaced locations along its length to provide multi-layer bundles.

A continuous line of laterally moving cigarettes is provided by extracting a row of cigarettes from an 80-column hopper 10, supporting the row by suction on the underside of a fluted beam 18 mounted on a pair of cranks 20, and cyclically rotating the cranks to bring the speed of the beam up to that of a fluted conveyor 32, where the row is deposited at the end of a previously transferred row. From the continuous line of cigarettes shorter rows are subsequently removed by known suction drums to form a succession of groups ready for packing on a continuous packer.

A reservoir system for cigarettes and other similar rod-shaped articles comprises a delivery conveyor arranged to convey the articles horizontally towards an inlet to the reservoir; a reservoir conveyor which lies below the delivery conveyor and is arranged to receive a stack of the articles delivered through the inlet and to run, when necessary, in a direction opposite to that of the delivery conveyor; a horizontally movable carriage carrying a movable end wall defining an end of the stack of articles on the reservoir conveyor adjacent to the inlet, and carrying also a sensor adjacent to the inlet which controls the direction (and possibly also the speed) of movement of the carriage; and an outlet for articles at the end of the reservoir conveyor towards which the latter moves.

A stack of sheets, in particular hinged-lid blanks B for cigarette packets, are disposed in a vertical stack S from the top of which successive sheets are lifted by a suction member and removed by mechanical means, e.g. by a pair of conveyors 21 provided with pushers 23.The suction member may be a gang of sleeves 14 to which suction is continuously supplied, so that when a sheet B is engaged by the sleeves they are lifted automatically by suction in readiness for the pushers 23 to remove the raised sheet B, after which the sleeves again drop by gravity. The stack S may be inched around a J-shaped stack, or lifted by a pair of divergent conveyors 30 to which replenishing groups of blanks G are fed from underneath.

Oval filter cigarettes are made by forming rod groups each comprising at least one cigarette portion and at least one filter portion in axial alignment; placing each rod group on a wrapping member rotatably carried by a conveyor having a succession of such wrapping members, each group being provided with a portion of uniting paper overlapping the members of the group; and rotating each wrapping member with respect to the conveyor about an axis parallel to that of the rods so as to wrap the uniting paper of least partly around the corresponding rod group.During rotation of each wrapping member the uniting paper may be gripped by suction ports to provide a tight wrap.

A mass flow of cigarettes is reduced in width as it passes downwardly through chutes into a passage in which the cigarettes are formed as a stream two rows deep. The cigarettes are fed onto a fluted drum and accelerated to form gaps between them, the cigarettes in one row being held by suction in the flutes and those in the other row resting on top of them and being kept in place by suction. From the fluted drum the cigarettes are transferred to a further fluted drum as a single row, by being fed between a stripper and a fixed plate which are positioned so that only one cigarette, from each row alternately, can pass into a flute on the further drum. The cigarettes may then be collated into groups ready for packing.
