Definitions

the present invention relates to a device for clipping and compressing tobacco for the formation of the sausage, comprising a pair of rotary clipping discs whose respective rotational speeds are identical, but in opposite directions with respect to the other, and compression means upstream of the discs relative to the direction of advancement of the rod and capable of compressing the tobacco over a determined length and cyclically on the rod, the compression zones corresponding each time to the ends of the cigarettes.
one of the first phases consists in the formation of a continuous rod, which is subsequently wrapped in paper before being cut into cigarettes.
This rod is clipped and must have tobacco "reinforcements" at regular intervals over a portion of determined length which corresponds, each time, to the end of cigarettes, in order to avoid the risk of tobacco leaking by one or by the two ends of the cigarette (depending on whether it is with or without a filter). In other words, this amounts to providing, at the ends, a density of tobacco greater than that which prevails in the body of the cigarette itself.
clipping and reinforcement are obtained by means of a pair of discs having grooves.
the surplus of tobacco which, as a rule, is included in an approximate range of 25-30%, is removed while the sausage will present, at regular intervals corresponding to the passage of the sausage by the throats, a larger quantity of tobacco which will be compressed in a second step, that is to say during the operation of wrapping the rod.
the two discs are not located in the same plane, but in two parallel planes, slightly offset from each other; they are not in contact.
Below the pair of clipping discs is an extraction wheel or brush which rotates at very high speed (approx. 5,000 - 10,000 rpm). The excess tobacco is returned to an evacuation bin.
Another known device includes two coplanar discs as a clipping means. res and provided with housings at their periphery, cooperating with a brush located below them, in an arrangement similar to FIG. 1. A cam placed upstream of these discs provides slight compression of the tobacco at the locations in which the discs provide an increase in thickness.
document DE-34 07 893 the use of fully flat coplanar discs is already known, but these discs are mounted and actuated so as to approach and move away cyclically from the perforated strip which guides and drives the flow of tobacco .
the function of the cyclic compression means is therefore provided in this case by the discs themselves, which leads to a complex arrangement of the device.
the present invention proposes means making it possible to effectively remedy the drawbacks observed which have just been exposed.
the tobacco clipping and compression device is characterized in that the clipping discs consist of circular knives in contact at their periphery, and in that the means ensuring cycles of tobacco compression are arranged under the said discs.
Fig. 3 shows in more detail the clipping and compression device 1. It can be seen that all the means according to the invention are brought together in a very compact unit essentially consisting of a pair of knife disks 3, 4, the front disk 3 being completed by a protective plate 5, a rotary cam 7 and a casing 2 housing the members for transmitting movements to the mobile elements 3, 4, 7.
Discs 3 and 4 are arranged in a mix me plan and have, on their periphery, a bevel or chamfering 3 ′, 4 ′ complementary to each other as can best be seen in FIG. 4A.
Their contact 21 extends over a generatrix of the truncated cone formed by the chamfering of the discs; this generator is included in the plane formed by the axes of rotation 20, 20 ′.
the clipping discs perform the function of real scissors:
the "input" flange 11 is thus subjected to a sharp shear, which makes any additional means of extraction superfluous.
the surplus of tobacco 13 falls by gravity and is immediately transported in an evacuation casing not shown; any re-aspiration of clipped tobacco is thus ruled out. Likewise, the whipping of tobacco particles is avoided.
Cam 7 has an active profile 17 or 18, the shape of which is studied as a function of the desired result.
the top of the active profile 17, resp. 18 (fig. 5A, 5B) during the compression phase, will correspond approximately to the plane of the discs.
the compression of the tobacco will take place only once during a rotation and will extend over a determined length which is a function of the geometry of the cam and the speed of advance of the rod. Depending on the profile of the cam, this compression will be uniform over said length (profile 17 of the cam 7 in FIG. 5A) or increasing, then decreasing over this same length (profile 18 of the cam 8 of FIG. 5B). Furthermore, it is obvious that one can provide cams allowing several compressions during a rotation, for example, two or three compressions.
the "outlet" rod 12 will therefore have, at regular intervals, zones 19 (fig. 6A) comprising more tobacco and which, when the paper is put in place, will be compressed again (19 ′ fig. 6B).
the representation of the zones 19 results from the fact that the tobacco from the sausage 12, previously compressed by the cam 7, resp. 8, decompresses immediately after passing through the clipping discs.
the device according to the invention brings together in a very compact unit all of the clipping and compression means. Thanks to the working mode of the discs, which play the role of shears making a clean cut of the flange, and thanks to the arrangement of the whole in a unit placed below the suction strip in a fixed position, the device ensures a significant improvement in the regularity of the flange and the compressed areas. Tobacco particles are spared as much as possible, all brushing, resp. extraction becoming superfluous. Likewise, any risk of re-aspiration in clipped tobacco is eliminated, which is subjected to simple gravitation and will be recovered in an evacuation casing.
