<heading id="h0001">TECHNICAL FIELD</heading>
<p id="p0001" num="0001">The present invention relates to an apparatus and method for splitting up articles of tobacco industry.</p>
<heading id="h0002">BACKGROUND</heading>
<p id="p0002" num="0002">The value of the tobacco or processed tobacco material needed to make a smoking article accounts for a large portion of the manufacturing cost of a cigarette, and therefore the recovery of tobacco, and now also other materials from defective articles, is a significant problem in the tobacco industry. Initially, mass-produced cigarettes did not have a mouthpiece, and the recovery of tobacco from cigarettes consisted only of tearing the wrapper, which was cut, for example, along the length of the cigarette. The mouthpieces attached to the tobacco portion of the cigarette were originally torn off manually.</p>
<p id="p0003" num="0003">The manual tear-off process has been mechanized, known in the art is a device for tearing off mouthpieces as disclosed in <patcit id="pcit0001" dnum="US2815029A"><text>US2815029(A</text></patcit>). Many devices are known in which cigarettes are cut transversely between the tobacco part and the mouthpiece by means of circular knives, such a device is disclosed, inter alia, in the document <patcit id="pcit0002" dnum="DE102004024433A1"><text>DE102004024433 (A1</text></patcit>). Recovering tobacco from double cigarettes is disclosed in, inter alia <patcit id="pcit0003" dnum="US3233613A"><text>US3233613(A</text></patcit>), <patcit id="pcit0004" dnum="US3345991A"><text>US3345991(A</text></patcit>), <patcit id="pcit0005" dnum="US3382874A"><text>US3382874(A</text></patcit>). The disadvantage of devices using circular knives is the inadvertent cutting of thin slices of the filter material from the mouthpiece, and cutting off narrow strips of metal or producing metal filings in the case of cutting an article having a segment provided with a plate for induction heating of the tobacco material. The above problems result from the inaccurate positioning of the cigarette during cutting and the tolerance of the length of the mouthpieces and tobacco parts. In addition, a disadvantage of such devices is the production of paper and tobacco dust.<!-- EPO <DP n="2"> --></p>
<heading id="h0003">SUMMARY OF THE INVENTION</heading>
<p id="p0004" num="0004">It would be therefore desirable to develop novel solutions for splitting up of tobacco industry articles which overcome at least some of the drawbacks of the prior art solutions discussed above.</p>
<p id="p0005" num="0005">The device according to the invention is intended for splitting up articles of the tobacco industry, which enables the recovery of materials from individual parts of the article independently of one another. There is presently a need to recover both the filler material and the elements within the filler material that need to be separated from the filler material. Due to the variety of materials being used, it is necessary that to each part of the article it is possible to apply a recovery technology suitable to the particular type of the material, usually the technologies for the various materials differ so much that they cannot be effectively applied without splitting up the parts of the article. The separation of the parts is particularly important for a part of the article consisting of several components, for example a part in which the filling material has at least one flavor capsule, a plate or any other insert. The solution according to the invention is suitable for splitting up various types of rod-like articles of the tobacco industry, for example tobacco filled cigarettes, tobacco filled cigarettes having a mouthpiece and smoking articles having a filter portion and a tobacco flavor-producing material portion by heating or otherwise, for example, by crushing a capsule filled with a liquid aromatic substance. In the case of separated segments containing tobacco material with a metal plate located inside the material, a further process of recovering the tobacco material includes, for example, cutting the wrapper and removing the plates with a magnet positioned, for example, over a vibrating conveyor transporting a mixture of tobacco material, the wrapper and the plates. The next step is to separate the tobacco material from the wrapper by means of a vibrating sieve.</p>
<p id="p0006" num="0006">The advantage of the device according to the invention is that the material of the individual parts of the article is not disturbed, no particles of filling material or components of the parts of the article are produced that are difficult to separate from the material of an adjacent article part.</p>
<p id="p0007" num="0007">In particular, the invention relates to an apparatus for splitting up articles of tobacco industry into fragments, wherein the rod-like article comprises a filling material wrapped in a wrapper. The apparatus comprises: a carrying unit with<!-- EPO <DP n="3"> --> recesses arranged to receive the rod-like articles, a holding unit arranged to hold the rod-like article in the recess of the carrying unit, a splitting unit comprising a pressing surface, wherein the pressing surface is positioned adjacently to the carrying unit, wherein the distance between the pressing surface and the bottom of the recess decreases during movement of the carrying element, which causes dislocation of a fragment of the rod-like article that is outside the recess and creates a breaking stress in the wrapper material at a boundary between the fragment located in the recess and the fragment located outside the recess.</p>
<p id="p0008" num="0008">The splitting unit may be a stationary unit. The pressing surface of the splitting unit may be arcuate or may be flat.</p>
<p id="p0009" num="0009">The splitting unit may by a rotary unit. The pressing surface may move in the same direction as the movement of the recess of the carrying unit or may move in the direction opposite to the movement of the recess of the carrying unit. The pressing surface may have a form of a recess in the splitting unit. The pressing surface may be a cylindrical surface.</p>
<p id="p0010" num="0010">The carrying unit may be a rotary unit. The apparatus may comprise a rotary supporting unit with supporting recesses, wherein the supporting recesses of the supporting unit may coincide with the recesses of the rotary carrying unit in an axial view, such that a pair of recesses comprising the recess in the rotary carrying unit and the supporting recess in the rotary supporting unit is arranged to receive the rod-like article.</p>
<p id="p0011" num="0011">The carrying unit may be a linear carrying unit and may move partially in linear motion. The apparatus may comprise a linear supporting unit with recesses, wherein the linear supporting unit moves at least partially in linear motion, and the recesses of the linear supporting unit coincide with the recesses of the linear carrying unit such that a pair of the recesses comprising a recess in the linear carrying unit and a recess in the linear supporting unit is arranged to receive the rod-like article.</p>
<p id="p0012" num="0012">The distance between the pressing surface and the bottom of the recess may decrease to zero during movement of the carrying unit.</p>
<p id="p0013" num="0013">The present invention also relates to a method for splitting articles of tobacco industry into fragments, wherein the rod-like article comprises a filling material wrapped in a wrapper, comprising the steps of: placing a rod-like article in the recess of the carrying unit, holding the rod-like article in the recess of the<!-- EPO <DP n="4"> --> carrying unit, pressing the rod-like article by means of the pressing surface of the splitting unit located adjacent to the carrying unit, decreasing the distance between the pressing surface of the pressing unit and the bottom of the recess during the movement of the carrying unit, which causes dislocation of a fragment of the rod-like article that is outside the recess and creates a breaking stress in the wrapper material at a boundary between the fragment located in the recess and the fragment located outside the recess.</p>

<heading id="h0005">DETAILED DESCRIPTION</heading>
<p id="p0015" num="0015"><figref idref="f0001">Fig. 1</figref> shows an exemplary rod-like article 1 in a form of a filter rod comprising a filling material in a form of segments A, B, C and D, wherein the segments are wrapped in a wrapper material W. Thus the presented rod-like article 1 is a multi-segment rod, in which the segments A, B, C, D are wrapped by a common wrapper material W. 1A denotes a part of the filter rod 1 comprising the segment A, the parts 1B, 1C, 1D comprise the segments B, C and D respectively. <figref idref="f0002">Fig. 1a</figref> shows a multi-segment rod 2 of a double length with respect to the single multi-segment rod 1, wherein the multi-segment rod comprises two<!-- EPO <DP n="5"> --> multi-segment rods 1 which are connected to each other. Cutting apart the multi-segment rod 2 in a production process results in two multi-segment rods 1, wherein the cutting is performed in the middle of the double multi-segment rod 2D.</p>
<p id="p0016" num="0016"><figref idref="f0003">Fig. 2</figref> shows a first embodiment of the apparatus for splitting up rod-like articles, comprising a carrying unit 3, a holding unit 4 and a splitting unit 5. The carrying unit 3 is made as a rotary unit and has a form of a drum with an axis of rotation k. The rotary carrying unit 3 rotates in a direction T. The rotary carrying unit 3 comprises recesses 6. In the presented embodiment the recesses 6 have a form of cylindrical grooves arranged on the peripheral surface of the carrying unit 3, wherein an axis t of the groove 6 is in parallel to the axis of rotation k of the carrying unit 3. The holding unit 4 has a form of a section of a cylinder and is arranged coaxially with the rotary carrying unit 3. The holding unit 4 is distanced from the peripheral surface 3A of the carrying unit 3 such, that the holding unit 4 slidably holds or presses the rod-like article 1 located in the recess 6, i.e. the distance between the holding surface 4A of the holding unit 4 and the peripheral surface 3A is close to the length of the radius of the recess 6 or it is close to the radius of the rod-like article 1 (<figref idref="f0003">Fig. 2a</figref>). The splitting unit 5 may be of any shape, in the presented example it has the form of an arcuate plate when viewed in a direction parallel to the axis k. The splitting unit 5 is stationary. The splitting unit 5 has a pressing surface 5A, which intersects the path of movement of the rod-like article 1. In the presented embodiment the pressing surface 5A is concave, and has a form of a section of the cylinder, wherein the pressing surface 5A may have other concave shape, for example the cross-section of the pressing surface may be a portion of an ellipse or a spiral.</p>
<p id="p0017" num="0017">The rod-like article 1 is placed in the recess 6. During rotation of the carrying unit 3, the rod-like article 1 is carried in the recess 6 and is guided by the holding unit 4, such that the rod-like article 1 is held, pressed and guided by the holding unit 4, owing to this the rod-like article 1 abuts the recess 6. A fragment of the rod-like article 1 is outside the recess 6, namely the part 1A, while the remaining fragment is in the recess 6, namely the parts 1B, 1C, 1D. During rotation of the carrying unit 3, the end 1A of the rod-like article 1 is approached to the pressing surface 5A of the splitting unit 5. After approaching, during further movement, the end 1A is deformed under producing shear, bending and torsion<!-- EPO <DP n="6"> --> stresses which are destructive to the wrapper material W, whereby the wrapper material W is torn at the boundary between the fragment located in the recess and the fragment located outside the recess. For simplification, in a drawing the torn end 1A has the wrapper material presented as cylindrical with a circular splitting line, however in reality the splitting line has a random irregular shape such as after tearing the wrapper. The distance e between the concave pressing surface 5A and the bottom of the recess 6 decreases during rotation of the carrying unit 3.</p>

During the rotary movement of the carrying unit 3 the surface 5A causes the part 1A to be detached from the rest of the rod-like article 1, wherein the front surface of the segment B is shown in <figref idref="f0003">Fig. 2a</figref></p>
<p id="p0019" num="0019">The splitting unit 15 presented in the second embodiment in <figref idref="f0003">Fig. 2b</figref> has a form of a flat plate and may be used in place of the splitting unit 5.
