Abstract:
Rod-shaped articles such as cigarettes are stored in a hopper (12) and transferred into a single cigarette column. The bottom cigarette in the column is pushed by an inserter rod (28) into an aperture (32) in a mandrel (30). The mandrel has a plurality of spaced apertures which can be filled with the desired collation. The mandrel is controlled by a Cartesian robot which moves the position of mandrel with respect to the inserter rod so that all the required apertures can be filled. The entire collation is then removed to a collation pocket (40) by a set of transfer rods spaced to match the apertures in the collation mandrel. In the pocket neighbouring cigarettes are brought into contact and the collation can them be packaged.
Abstract:
An infusion package, particularly for coffee, has a container part 12 and a support 14 for the container part. The container part 12 defines two compartments, 36, 38 which contains similar amounts of coffee. In one form each end portion of the support 14 has crease lines which facilitate opening of the package for use. Also disclosed is an apparatus and method for making the package.
Abstract:
A sealing conveyor (80) is arranged at the exit of a machine for producing wrapped articles. The conveyor includes a series of packets (82) and carries heat sealing means which may be pivotally mounted. Discharge means (86) operate transversely of the conveyor to transfer sealed articles towards an exit station. Where the articles are packages they may be produced on a twin line machine for subsequent supply to a double bundle cigarette packaging machine. Such packages may contain different number of cigarettes supplied from a hopper (10) by a common transfer conveyor (18) to separate parallel wrapping lines (40A, 40B).
Abstract:
Apparatus for manufacturing a DOY bag includes flow formers (24, 28) for causing a moving web (20) to have a transverse cross section which comprises two arms (20a) each having a free end coinciding with a respective lengthwise extending edge (20b) of the web and a portion interconnecting the arms which extends inwardly into the space between the arms. Heated sealing rollers (30) disposed downstream of the flow formers seal the web to form successive closed compartments (38). A device (36) feeds a flowable material into the space between the arms (20a) at a position upstream of the sealing rollers (30) such that each compartment (38) contains a predetermined amount of the flowable material. The apparatus preferably operates continuously producing between 300 and 1000 bags per minute.
Abstract:
The invention provides a method of and apparatus for handling objects, such as flattened bags (4') on a packaging line. An open topped container (3; 401) is carried at the top of a flanged member (9) carried by a carriage (6) which is moved by an endless chain (2) at a constant speed along a first path in a conveying direction (A) through a loading station. The container (3; 401) comprises two halves (24, 25) which are separated as the container (3; 401) moves through the loading station in order to allow a flattened bag (4'), which moves faster than the endless chain (2) along a second path which converges with the first path, to enter the container (3; 401) and the slow down to the same speed as the endless chain (2). The two halves (24, 25) then close thereby trapping the bottom seal (63) of the bag between the opposed portions (24d, 25d; 201, 202) at the bottom of the container (3; 401). Plenum chambers (47, 48) in the base of the container (3; 401) can be evacuated, as the container (3; 401) and bag (4') travel on, so as to effect evacuation of chamber which surrounds the bottom part of flattened bag (4') and is formed by the bottom walls (24d, 25d; 201, 202), the side walls (24a to 24c, 25a to 25c), and two stationary members (61, 62; 421, 422) under which the container (3; 401) is caused to pass causing the flattened bag (4') to open and conform closely to the interior of the container (3; 401).
Abstract:
In a packaging machine, particularly for producing hingedlid packets for cigarettes, groups of cigarettes conveyed on an endless pocket conveyor (16) become partially wrapped in a wrapper section (20) during transfer to a further endless pocket conveyor (24). In passing to the further conveyor the groups and wrapper sections pass through a forming member carried on an intermediate endless conveyor (22). Transfer of the groups is effected by cam-operated plunger units (26A) carried by a fourth endless conveyor (26). The machine further includes a packet transfer unit at which spaced packets are deposited on a suction belt (50) prior to delivery in abutment to a packet reservoir (54); and a blank feed unit (30) comprising a continuously-moving endless feed conveyor (62) provided with reciprocating pulleys, the movement of which causes the conveyor to remain stationary to allow transfer of blanks from a stationary reservoir (60).
Abstract:
A system for delivering rows of cigarettes, each for forming one layer of a bundle of cigarettes to be packed in a packing machine, includes a number of fluted planetary wheels (42) carried by an annular carrier (44) along a path on which cigarettes are picked up directly from the lower ends of channels (40) formed between vanes (38) in the hopper of the machine. The wheels (42) transfer the cigarettes in rows to flute sets (48) on a coaxial drum (46) from which the rows are further transferred to a delivery drum (22). Generally the packing machine includes three such systems, one for each layer of the bundle of cigarettes to be packed. In an alternative system cigarettes forming one row are picked up substantially simultaneously by row carriers (220) mounted on planetary wheels (226) so as to follow an hypocycloidal path.
Abstract:
There is provided a method of loading a container with a defined quantity of product (30). The method comprises closing off a perforation (12a, 12b) in a perforated plate (10); directing powder (30) into said closed-off perforation by the sweeping action of a first director blade (40) spaced from said perforated plate; and transferring the contents of the perforation to said container. The method is characterized by relative rotary motion of the perforated plate (10) and said first director blade (40). Suitable apparatus is also provided.
Abstract:
A packing machine includes a main packing module (10) which includes provision for concentric rotary packing conveyors (14, 16) which co-operate with stationary processing stations (34, 36) to perform an operation such as folding or sealing on a packet component (such as a blank or cigarette bundle) held in a pocket (18, 20). Different packet components (e.g. for slide and shell packets) may be conveyed in parallel by the conveyors, or, for complex packets, components may be moved in sequence by the conveyors, i.e. so that they progress spirally, possibly for more than 360 DEG , around the axis of the conveyors. For even more complex packets, components may be transferred to satellite turrets (22, 24) for further processing, possibly while being held in movable tooling such as pucks. In another embodiment an endless packing conveyor (100) has a series of pockets formed on pallets (102) whose mutual spacing around the endless path is variable. At least one transfer or operating station, or an exit station (146), may comprise a robotic module (134 etc.). The conveyor may co-operate with one or more subsidiary endless conveyors (100A etc.) forming sub-loops of the main endless path.
