Definitions

This invention relates to a machine for making at least one continuous rod of filter material or tobacco.
the object of this invention is applicable both to cigarette making machines and filter making machines.
Machines for making continuous rods of tobacco generally involve the use of a substantially vertical duct which is fed from below with a continuous flow of tobacco particles and at the top end of which there is a suction conveyor belt on which a semi-finished, continuous stream of tobacco is formed.
the suction belt is adapted to feed the semi-finished, continuous stream of tobacco along a predetermined path defined by the conveyor itself to a preforming device, which produces a continuous stream, and then to a station for forming a continuous tobacco rod where a web of paper is wrapped around the continuous tobacco rod to form a continuous cigarette rod or cylinder which is then cut into individual cigarettes by a cutting device.
the semi-finished, continuous stream is suitably preformed and progressively compacted by the preforming device comprising a tile-shaped member which gives the advancing semi-finished, continuous stream the correct transverse dimension.
the tile-shaped member controls and guides the semi-finished, continuous stream, compressing it after it has been deposited on the web of paper with which the continuous tobacco rod will be made.
cigarette filters As is known, the production of cigarette filters, on the other hand, involves processing a continuous strip of filter material, for example cellulose acetate, obtained from a bale of compressed filter material.
filter material for example cellulose acetate
the strip is made to advance along a predetermined path through processing stations where it is stretched lengthways and crossways and then sprayed with chemical additives such as, for example, triacetin.
Preforming devices located at a specific station then preform the semi-finished, cylindrical streams of filter material to make continuous streams of filter material.
each preforming device comprises a substantially funnel shaped duct with an end portion having the shape of an oblong tile into which the semi-finished, continuous stream is fed.
the tile-shaped end portion progressively reduces the transverse cross section of the stream until it becomes a continuous stream of predetermined diameter.
the continuous stream Downstream of the funnel-shaped element, the continuous stream is channelled into the respective forming channel of a garniture tongue where the continuous streams advance in defined, parallel directions in such a way as to form continuous rods of filter material which a rotary cutting device then cuts into separate filter sticks.
Each filter stick may have the length of one or more filter tips, depending on requirements, which will be applied to the cigarettes in the filter tip attachment machine.
the device which preforms semi-finished, continuous stream comprises an oblong tile-shaped member in which the semi-finished, continuous stream is channelled in order to progressively reduce the size of its transverse cross section until obtaining a continuous stream whose transverse cross section is substantially equal in diameter to the cigarettes or filters to be made.
the two machines have in common the fact of having a tile-shaped member designed to constrain and simultaneously compress the material (whether tobacco or filter material in the form of a semi-finished, continuous stream) into a forming channel of the garniture tongue so as to give it the transverse cross section of the size it needs to have in the garniture tongue.
the Applicant has observed that the continuous stream of filter material or tobacco feeding out of the tile-shaped members tends to loosen up and come apart and scattered. The Applicant has observed that this is due to the sharp edge at the top of the outfeed section of the tile-shaped member.
the progressive compression inside the tile-shaped member creates a state of tension in the filter material or tobacco, which causes the material to expand suddenly and instantaneously when it leaves the outfeed section, thus tending to loosen up and come apart.
the technical purpose which forms the basis of this invention is to propose a machine for making at least one continuous rod of filter material or tobacco to overcome the above mentioned drawbacks of the prior art.
this invention has for an aim to provide a machine for making at least one continuous rod of filter material or tobacco and which allows making a continuous stream of filter material or tobacco which keeps its shape and correct transverse cross section size.
Another aim of this invention is to provide a machine for making at least one continuous rod of filter material or tobacco and which allows increasing the efficiency of the rod production process and preventing particles of filter material or tobacco from being scattered and lost.
the numeral 1 denotes in its entirety a machine for making at least one continuous rod of filter material or tobacco made according to the teachings of this invention and hereinafter referred to simply as machine 1.
the machine 1 is configured to make continuous rods 100 of filter material "F” or continuous rods 100 of tobacco "T", both suitable for use in making cigarettes.
cigarette is used to generally denote a plurality of products or smoking articles such as, for example, cigarettes, cigars, cigarillos and the like.
the machine 1 comprises a process station 2 for processing filter material "F” or tobacco “T” to make at least one semi-finished, continuous stream 101 of filter material “F” or tobacco “T". More specifically, the process station 2 is adapted to receive the filter material "F” or the tobacco "T" to be processed.
the process station 2 for processing filter material “F” is configured to process the filter material “F” along a predetermined path along which the filter material “F” is processed to make at least one semi-finished, continuous stream 101 of filter material “F". More specifically, the process station 2 for processing filter material “F” comprises forming means used to obtain at least one continuous strip of filter material "F” which is in turn fed to longitudinal and transverse stretching means. Downstream of the stretching means, the process station 2 comprises a chemical unit for chemically treating at least one continuous strip of filter material "F", where the at least one strip is sprayed with chemical additives such as, for example, triacetin.
chemical additives such as, for example, triacetin.
the at least one strip Downstream of the chemical unit, the at least one strip is fed by a plurality of transfer rollers to pneumatic suction devices which transform the strip into a semi-finished, continuous stream 101 of filter material "F".
the process station 2 for processing tobacco "T” comprises, instead, a suction conveyor belt which is looped around end rollers, rotatable about parallel axes, and which has a lower section adapted to use suction to hold down particles of tobacco "T” coming from a vertical duct which is not illustrated and which is mounted under the lower section of the conveyor, to form a semi-finished, continuous stream 101 of tobacco "T".
the semi-finished, continuous stream 101 of tobacco "T” is suitable for being fed continuously by the lower section of the conveyor belt along a feed direction transverse to the axes of rotation of the end rollers.
the machine 1 comprises a pre-forming device 3 located downstream of the process station 2 and adapted to receive at least one semi-finished continuous stream 101 of filter material "F” or tobacco “T” in order to make at least one continuous stream 102 of filter material "F” or tobacco “T", as will become clearer as this description continues.
the machine 1 Downstream of the preforming device 3, the machine 1 then comprises a garniture tongue 4 adapted to receive the at least one continuous stream 102 of filter material "F” or tobacco and configured to form at least one continuous rod 100 of filter material "F” or tobacco "T".
the garniture tongue 4 has a forming channel 5 along which the at least one continuous rod 100 is progressively formed as it feeds along a forming feed direction "X".
the machine 1 comprises a wrapping station 6 configured to feed into the forming channel 5 a continuous strip of paper "C” which is progressively wrapped by the garniture tongue 4 around the continuous stream 102 of filter material "F” or tobacco “T” to make the continuous rod of filter material "F” or tobacco "T".
a wrapping station 6 configured to feed into the forming channel 5 a continuous strip of paper "C” which is progressively wrapped by the garniture tongue 4 around the continuous stream 102 of filter material "F” or tobacco “T” to make the continuous rod of filter material "F” or tobacco "T".
the machine 1 preferably also comprises a cutting device 7 - a rotary cutting device, for example - configured to cut the continuous rod 100 into individual segments, not illustrated.
the garniture tongue 4 for forming the continuous rod 100 has an infeed station with an endless conveyor 8, one portion of which extends under the conveyor belt of the process station 2 for processing the tobacco "T” or under the outfeed station of the pneumatic suction devices of the strip of filter material "F".
the endless conveyor 8 of the garniture tongue 4 is adapted to run along a feed direction parallel to the forming feed direction "X", at least partly inside a groove 9 of the garniture tongue 4 defining the bottom surface 5a of the forming channel 5.
the endless conveyor 8 forces the continuous strip of paper "C”, if present, to be wrapped progressively round the continuous stream 102 of filter material "F” or tobacco "T".
the continuous stream 102 is fed to the garniture tongue 4 by the preforming device 3 which is interposed between the feed station 2 and the garniture tongue 4 itself.
the preforming device 3 comprises at least one oblong tile-shaped member 10, hereinafter referred to simply as tile 10, having a directrix "D" which makes a first defined angle " ⁇ " with the forming feed direction "X".
the first defined angle " ⁇ " defines the inclination of the tile 10 relative to the forming feed direction "X".
the first defined angle " ⁇ " between the directrix “D" of the tile 10 and the forming feed direction is between 0° and 2°, and still more preferably, 0.5°.
the tile 10 has an inside surface 10' which is configured to progressively reduce the transverse cross section of the semi-finished, continuous stream 101 feeding along it between an infeed portion 10a and an outfeed portion 10b of the tile 10 itself and to channel the stream into the forming channel 3.
the preforming device 3 also comprises a connecting member 12 which blends the tile 10 with the forming channel 3 of the garniture tongue 4 and which is configured in such a way as to allow the semi-finished, continuous stream 101 to be progressively compacted.
the connecting member 12 has an inside surface 12' which blends smoothly with the inside surface 10' of the tile to define an intermediate connecting feed path P.
the semi-finished, continuous stream 101 of filter material "F" or tobacco undergoes a step of compacting along the intermediate connecting feed path P which prevents an abrupt passage between the end portion 10b of the tile 10 and the forming channel 5.
the end portion 10b of the tile 10 corresponds to an infeed portion 12a of the connecting member 12.
the connecting member 12 allows the semi-finished, continuous stream 101 to be gradually compacted before it leaves the forming channel 3 and enters the forming channel 5 as continuous stream 102 so that its newly-formed transverse cross section remains unchanged in size as far as possible.
the connecting member 12 accompanies the semi-finished, continuous stream 101, which is progressively transformed into continuous stream 102, towards the forming channel 5 more smoothly and less abruptly compared to the sharp edge formed by the end portion 10b of the tile 10, thus preventing the compressed particles of filter material "F” or tobacco "T” from instantaneously expanding and scattering into the environment and causing the newly-formed continuous stream 102 to lose its shape.
the connecting member 12 has an outfeed portion 12b defining with the groove 9 the transverse cross section of the continuous rod 100 of filter material "F" or tobacco to be made.
the connecting member 12 thus allows stabilizing the shape and transverse cross section of the continuous stream 102 before the continuous stream is formed in the garniture tongue 4 to obtain a continuous rod 100 of excellent quality.
the connecting member 12 allows preventing loss of particles of filter material "F” or tobacco “T” and, in particular, prevents the filter material “F” from “exploding” (especially if the filter material “F” comprises charcoal) and prevents the particles of tobacco “T” from scattering.
the continuous stream 102 feeding out of the outfeed portion 12b of the connecting member 12 is compressed and compact; that way, the filter material "F” and the tobacco “T” keep their shape and are prevented from breaking up/scattering.
the connecting member 12 preferably defines a straight intermediate connecting feed path P.
the straight intermediate connecting feed path P is substantially parallel to the forming feed direction X.
the inside surface 12' of the connecting member 12 is defined by a semi-cylindrical portion which is parallel to the forming feed direction "X".
the semi-finished, continuous stream 101 feeding out from the end portion 10b of the tile 10 is made to advance along an intermediate connecting feed path P which ensures that the semi-finished, continuous stream 101 adopts a constant cross section along the entire path P so as to effectively compact the filter material "F" or the tobacco "T” of the semi-finished, continuous stream 101.
the transverse cross section imparted to the semi-finished, continuous stream 101 feeding along the straight intermediate connecting feed path P is advantageously maintained by the continuous stream 102 as it leaves the outfeed portion 12b of the connecting member 12 and enters the forming channel 5.
the connecting member 12 preferably defines a curved intermediate connecting feed path P.
the inside surface 12' progressively blends in asymptotic manner the end portion 10b of the tile 10 with the outfeed portion 12b of the connecting member 12, defining, for example, an ideal pseudospherical portion.
the semi-finished, continuous stream 101 is compressed and compacted more gradually, smoothly and less abruptly compared to the case where only the tile is present, thus guaranteeing correct compacting of certain types of tobacco "T” or filter material "F".
the pre-forming device 3 preferably also comprises, at an outfeed portion 12b of the connecting member 12 between the connecting member 12 itself and the garniture tongue 4, an upwardly-diverging tile shaped end member 13 having a respective directrix "D1" making a second defined angle " ⁇ " with the forming feed direction "X".
this end member 13 besides accompanying the continuous stream 102 as it leaves the connecting member 12, also has a safety function and that is to prevent any fragments or particles of filter material "F” or tobacco "T” which might in any case come away from the continuous stream 102 from being dispersed into the surrounding area and jamming the machine 1 or negatively affecting its operation.
the second defined angle " ⁇ " between the directrix “D1" of the end member 13 and the forming feed direction "X" is between 0° and 10°.
the second defined angle " ⁇ " between the directrix "D1" of the end member 13 and the forming feed direction "X" is equal to 2°.
the connecting member 12 defines a straight intermediate connecting feed path P and the inside surface 12' of the connecting member 12 has a directrix "D2" diverging upwards relative to the directrix "D" of the tile-shaped member 10 (in such a way as to define a frusto-conical portion) and making a third defined angle " ⁇ " with the forming feed direction "X".
the connecting point between the inside surface 12' of the connecting member 12 and the inside surface 10' of the tile is made curved so that the two surfaces are smoothly blended with each other.
This invention achieves the preset aims by overcoming the above mentioned disadvantages of the prior art and providing the user with a machine 1 which allows making at least one excellent quality continuous rod of filter material or tobacco thanks to the presence of a connecting member 12 disposed between the forming channel 5 and the tile 10, ensuring that the continuous stream 102 formed is effectively compressed and compacted.
