No. 400,699 Claims priority, application Great Britain, Oct. 4, 1963, 39,207/63 6 Claims. (Cl. 93-1) ABSTRACT OF THE DISCLOSURE Apparatus is disclosed for making a composite rod of cigarette filters, including powdered filter material e.g. charcoal. An endless belt having spaced pockets is used to transfer the powdered material from a hopper to spaces between filter plugs traveling in a stream, with a continuous wrapper on a conveyor. Said belt has an upper run closing a discharge opening in the base of the hopper, and a lower run traveling immediately above the stream of plugs.
This invention relates generally to apparatus for producing composite filter plugs for cigarettes and more particularly to apparatus for producing a complete filter rod having portions of powdered filter material interposed between conventional plugs at regular intervals.
In the manufacture of filter-tipped cigarettes, it is a common practice to roduce a rod of filter material wrapped in paper and thereafter to cut such rod into lengths sufiicient for individual cigarettes; not infrequently the rod is first cut into lengths sufficient to furnish tips for two cigarettes, then placed between two cigarette lenghs (i.e. lenghs of tobacco Wrapped in paper) and united therewith by a suitable band, whereafter the doublelength portion of rod is cut in half to yield two tipped cigarettes. Such rods of filter material have been made as composite rods, i.e. containing two or more kinds of filter material, as for example one kind of filter material selected solely for its filtering efliciency, and another kind of filter material selected for its attractive appearance, the rod being then made and applied to cigarette lengths in such manner that the latter filter material appears at the end of the finished cigarette while the former filter material is interposed between the latter filter material and the tobacco.
Hitherto, however, the filter materials employed have been relatively coherent materials, e.g. paper or cotton wool, but it is now desired to improve the filtering efficiency by employing powdered material e.g. granules of activated carbon. With such material, it will be appreciated that there are practical difficulties in following the conventional practice of first forming short plugs of each filter material and then marshalling such plugs to construct a filter rod, even though some conventional plugs are still required, as powdered material is not suitable for the exposed end of a cigarette. It is an object of the present invention to provide apparatus with which filter rod containing powdered material may be made.
According to the invention, there is provided apparatus for producing composite filter rod including portions of powdered material, comprising means for feeding filter plugs in succession on to a continuous wrapper with gaps between successive plugs at regular intervals, means for filling said gaps with powdered material, and means for folding said continuous wrapper around said plugs and said material to form a continuous rod.
The plug feeding means is arranged to move the plugs United States Patent M Patented Oct. 24, 1967 and the wrapper substantially horizontally through a loading zone, and the filling means comprises an endless flexible conveyor band having regularly-spaced carrier pockets therein, said band being so arranged that a lower run of the band travels through the loading zone imme diately above said plugs with the pockets facing downward above the gaps between successive plugs, further means being provided for filling each of said pockets with the powdered material between successive passages of the pocket through the loading zone.
The folding of the wrapper may be performed by stationary folding blades, generally known in the art as a garniture, and preferably such blades are so placed that intitial folding, to bring the wrapper to a U section, is effected at each part of the wrapper before that part passes through the loading zone, so that the powdered material is not lost over the side edges of the wrapper.
In order that the invention may be fully understood, a preferred embodiment thereof will now be described in some detail, referring to the accompanying drawings, in which:
FIGURE 1 is a sectional elevation of part of a filter plug rod producing machine;
FIGURE 2 is a fragmentary section on line VV of FIGURE 1; and
FIGURE 3 is a fragmentary plan view, from above, of a detail of the apparatus shown in FIGURE 1.
As seen in the drawings, two toothed wheels 35 mounted on parallel horizontal shafts 36 carry an endless conveyor band 37 so that it has horizontal upper and lower runs as indicated at 38, 39 respectively. Below and parallel with the lower run 39 of band 37 is the top run of an endless conveyor belt 40, which in operation moves from right to left as seen in FIGURE 4, while wheels 35 rotate clockwise so that lower run 39 of band 37 also moves from right to left at the speed of belt 40. The belt 40 is supported by a base-plate 41 across which said belt slides, and although the whole length of belt 40 is not shown it will be understood that it has a return run below base-plate 41, and at some convenient place on said return run the belt 40 passes around a driving pulley connected to a prime mover which is also connected to shafts 36 by any convenient form of transmission device (not shown). The belt 40 emerges from below the base-plate 41 to the right of said plate and there passes over a guide pulley 42.
To the right of pulley 42 a further pulley 43 guides a continuous paper wrapper strip 44 fed from a supply reel (not shown), also below base-plate 41, said strip 44 being fed on to the belt 40. A succession of filter plugs P are fed from the right as indicated by arrow PF by any suitable means (not shown) driven by the same prime mover on to the strip 44 at regularly spaced intervals. As shown, each plug P is equally spaced from the preceding and succeeding plugs but it is noted that other arrangements are possible e.g. the plugs may be fed in pairs, with no gap between the two plugs of each pair.
The band 37 is toothed on its inner face, the teeth on said band being complementary in the form to the teeth of wheels 35 so that the drive to band 37 is positive. On its outer surface band 37 has regularly-spaced pockets 45, the spacing of said pockets being equal to the spacing of successive gaps between plugs P and the connections from the common prime mover (not shown) to shaft 36 and to the plug feeding means being so arranged that each pocket 45 as it travels along the lower run 39, immediately above plugs P, is aligned with one of said gaps.
Above the upper run 38 of band 37 is a powder hopper 46, said hopper having in its base an elongated discharge opening of dimensions such that it is closed by said upper run 38. Immediately above said discharge opening the hopper 46 has a set of vertical guide vanes 47 to promote smooth flow of powder down tothe opening. It will be understood that such vanes may be omitted if a powder having no tendency to clog is used, while if a powder containing relatively large granules, or otherwise especially susceptible'to clogging, is in use the vanes 47 may need to be movably mounted and provided with some form of agitator. The powder employed may for example be granules of activated carbon.
A retaining plate 48 bears against the outer surface of band 37 around the right-hand wheel 35, the plate 48 being fitted with side plates 49 overlapping the band and wheel slightly, so as to close the pockets 45 as they pass from the upper run 38 to the lower run 39.
The base-plate 41 is of composite construction, comprising a main member 41a to the upper surface of which two parallel spaced strips 41b are secured. Together these three members define a central trough in which belt 40 and wrapper 44 travel. Below the lower run 39 of band 37 the form of the trough is as illustrated in FIGURE 2, but immediately above pulley 41 the trough is wider and its central portion is more gently curved, to avoid a sudden change in the form of belt 40 as it leaves pulley 41. p
In operation, as any given pocket 45 of band 37 travels from left to right in the top run 38, it fills with powdered filter material from the hopper 46, and then as that pocket travels round the right-hand wheel 35, the powdered material is retained in the pocket by plate 48. As the pocket leaves that wheel 35 and enters the lower run 39, the powdered material is free to fall and does so; as the pocket is aligned with a gap between two successive plugs P, the falling powder fills said gap, being retained there by the adjacent plugs and by the wrapper 44 in view of the trough-like configuration to which the said wrapper and the belt 40 have been brought at this stage (FIGURE 2). During its passage along the lower run 39, each pocket 45 has time to empty itself completely, even at high speeds of operation, so that a measured quantity of powdered filter material is delivered to each gap between successive plugs P. At the left-hand end of said lower run 39, each pocket 45 travels round the left-hand wheel 35 to be filled again, while plugs P and wrapper 44, with powdered filter material filling the gaps between the plugs, are fed to the left for further folding and sealing of the wrapper 44 in known manner to produce a wrapped composite filter r-od.
