Definitions
- the present invention relates to a device for separating a rod-shaped segment of the tobacco processing industry from a strand with the features of the preamble of claim 1 and a method for separating a stab-shaped segment of the tobacco processing industry from a strand with the features of the preamble of claim 9th
- Such devices and methods are used in a strand unit in which the rod-shaped segments are separated from an endless strand in a predetermined length.
- such devices and methods are also used to separate segments from a strand which has a double or multiple finite length in relation to the length of the segments.
- the term strand is understood to mean both endless strands and finite strands, ie bars with a multiple length in relation to the segments.
- Such segments are e.g. used in so-called heat-not-burn products (HNB products).
- the segments are assembled in the manufacture of the HNB products after separation in a predetermined arrangement and connected to each other by means of a glued wrapping strip.
- Such segments and HNB products are e.g. from the publication WO
- One type of segment in the HNB product is formed by a tubular body, which is formed from one or more layers of cellulose with a total mass of 200 g / sqm.
- the tubular body is thus formed as a relatively thick and rigid cardboard with a comparatively high cutting resistance.
- the cut edge of the segments should be as burr-free as possible so that the finished products made up of the segments have the highest possible quality and smooth surface. It is also important for the further transport, storage and further processing of the segments that they have the highest possible burr-free
- the segments are separated from the strand by means of a cutting unit with a cutting knife with one or more cutting edges, which penetrates into the strand with increasing depth during the cutting process and thereby completely separates the segment from the strand over the entire cross-sectional area.
- the cutting knife can be arranged on a rotating knife carrier and can have a cutting edge that extends radially obliquely outwards.
- the knife holder is arranged with the cutting knife so that it is with the cutting edge during the rotary movement completely over the entire cross-sectional area, ie over the entire diameter through the
- Such a cutting knife is preferably used to separate the segments from an endless strand in the strand unit.
- the endless strand is during the
- the cutting process in the area of the cutting knife is fixed by a strand receptacle forming a counter bearing in the form of a tube with a slot, the tube being aligned with the slot during the cutting process in such a way that the cutting knife moves the strand through the slot during the cutting process and thereby the Strand cuts.
- the cutting knife can also be designed in the form of a round disk with a circular cutting edge.
- the cutting knife is fixed in this case and directed with the cutting edge on the outer surface of a transport drum in a drum barrel.
- the outer surface of the drum is provided with a plurality of troughs, in each of which a finite strand of multiple lengths is transported.
- the drum has one or more revolving
- the cutting knife is arranged so that it dips into the groove with the cutting edge, so that the strands held in the troughs are cut into two or more segments as they pass the cutting knives. If several cutting knives such as three cutting knives are provided, the respective strand can be cut into four segments in this case with one revolution of the drum.
- the troughs or partial troughs form a strand receptacle forming a counterbearing for the strand, which in this case is finite, during the cutting process.
- Both embodiments have in common that the cutting knife travels completely through the strand in an arcuate cutting movement, by penetrating the strand on one side while overcoming the cutting resistance, then cutting through the strand over the entire diameter until it cuts finally exits the strand on an exit side.
- the cutting knives In order to achieve a high quality cut at a high production speed, the cutting knives have to be reground as an option. In addition, it is necessary that the cutting edge is immersed in the strand with a certain cutting force in order to overcome the cutting resistance of the strand. If a correspondingly dimensionally stable material with a high cutting resistance is used, comparatively high cutting forces must be applied accordingly.
- the invention is based on the object of providing a device and a method for separating rod-shaped segments of the tobacco processing industry from one strand, which is an inexpensive manufacture of segments with a burr-free cutting edge and a high production capacity should make possible.
- a device for separating a rod-shaped segment of the tobacco processing industry from a strand is proposed with the following features:
- the cutting unit is designed and set up such that the cutting knife cuts the strand over the entire diameter during the cutting process, wherein
- a manipulation unit that manipulates the cut surface of the segment is provided, which is arranged adjacent to and / or downstream of the cutting unit with respect to a transport direction of the segment.
- the cutting unit is designed and set up such that the cutting knife cuts the strand over the entire diameter during the cutting process, wherein
- Cut surface of the separated segment is reworked.
- the achievement of the invention is to be seen in the fact that the quality of the segments is not achieved by improving the cutting process with the cutting edge of the cutting knife with the complex measures described above, but instead that even burr formation on the segment is consciously accepted, however, this is actively eliminated or at least minimized by the manipulation unit in closing or parallel to the cutting process.
- This enables burr-free segments to be produced at a high cutting speed, which in turn enables a high production capacity to be achieved.
- the term cut surface is not only to be understood as the pure end surface of the segment.
- the cut surface in the sense of the invention should also be understood to mean the material of the segment which has been displaced by the cutting process and has been thrown up to the side of the ridge, i.e.
- a combination unit is provided downstream of the manipulation unit in relation to the transport direction of the segment, in which the segments are combined with one or more further segments in a coaxial arrangement to form rods of greater length.
- the proposed arrangement of the manipulation unit seen before is advantageous in that it eliminates the burr before the segments are joined in the combination unit, which in turn has the advantage that the segments in the combination, ie in the arrangement adjacent to one another, have a rod with a Form a high quality surface.
- a wrapping unit is provided downstream of the manipulation unit and / or the combination unit in relation to the transport direction of the segment, in which the segment is larger with one or more further segments by means of a wrapping strip to form a rod Length is connected.
- the wrapping strip can be placed around the segments in a very close arrangement due to the absence of burr, and the segments can be made into a rod with a cylindrical surface with a very high surface quality, i.e. without any unevenness, such as bumps or dents.
- the manipulation unit comprise a non-abrasive shaping unit. Due to the non-abrasive forming unit, a burr on the edge of the segment to a homogeneous surface can be removed by not tearing or separating the material, but Instead, it is pushed to the defined shape in a displacement process without loss of material, which ideally corresponds to the shape of the cut segment without deformation of the edge side or the cut surface or at least approximates it.
- the molding unit can consciously have a molding surface which presses the segment into a defined shape at least in the region of the cut end under a pressing force.
- the molding surface forms a die, which defines the shape of the segment after passing through the molding unit through its negative shape.
- the shaped surface can be formed by an inner or outer cone, which is embossed axially and / or radially on the cut surface of the segment.
- the proposed solution has the advantage that the reshaping of the edge is carried out continuously, that is to say continuously, because of the conicity of the molding surface, and since it is particularly gentle on the material.
- Such a solution is particularly advantageous if the segments are circular cylindrical or even annular cylindrical, thus tubular, and the inner or outer cone is formed by a centering mandrel or ring with a corresponding conical ring surface. As a result, the segments are simultaneously centered when the cone is inserted or attached and are thus deformed and loaded evenly over the circumference.
- the shaped surface can also be formed by a fixed rolling surface, on which the segments are forced to roll around their longitudinal axes by a frictional engagement.
- the segments roll over the circumference during the Rollbe movement, whereby a possible radial burr is pushed back into the material of the segment.
- the Segments roll on the rolling surface practically automatically to a smooth, cylindrical surface. Since the proposed solution does not require a further process step and only requires a rolling surface provided on a drum, this solution can be implemented particularly easily. Furthermore, a particularly smooth and gentle shaping process of the cut surface of the segment can be realized by the rolling movement.
- the fixed rolling surface has a guideway with a width corresponding to the length of the segments, the guideway being arranged such that the segments in the guideway perform a guided rolling movement transversely to their longitudinal axes.
- the guideway is formed here by a recess or groove which is exactly wide enough that the segments are guided therein with longitudinal axes oriented perpendicular to the longitudinal direction of the guideway.
- the edges of the segment in the base of the guideway are shaped particularly well by correspondingly inclined inner edges of the guideway.
- the segments are held in receptacles on a lateral surface of a cylindrical drum which can be driven in rotation about an axis of rotation, and the rolling surface is formed by a curved counter surface which is arranged concentrically to the axis of rotation. Due to the proposed curved and concentric arrangement of the rolling surface, the distance between the rolling surface and the lateral surface of the drum or the base surfaces of the receptacles during the running movement of the drum is essentially constant, and the segments roll under a load that is as uniform as possible.
- the counter surface can preferably be arranged at a distance from the base of the receptacles, which corresponds to the diameter of the segments minus 0.2 to 1.5 mm. Due to the undersize of 0.2 to 1.5 mm, a pressure which increases the frictional closure is exerted on the segments, which favors the rolling movement of the segments on the rolling surface and prevents the segments from slipping.
- the distance in the transport direction can be designed to be convergent, so that the contact pressure exerted rises continuously, or is slowly increased in a manner that is gentle on the material.
- the distance is only slightly converging, so that the pressure force exerted is increased only very slightly and slowly.
- the distance can, for example, be reduced from an undersize of 0.2 mm to an undersize of 0.6 or 0.8 mm on the outlet side with a developed length of the counter surface of approximately 50 to 100 mm starting from the entry side.
- the rolling surface can be designed such that it can be adjusted in terms of distance and / or angle so that it can be aligned once before adapting the device to the segments to be produced.
- the rolling surface can be designed to be pivotable both about a pivot axis oriented parallel to the axis of rotation of the drum and with respect to a pivot axis oriented perpendicularly thereto.
- various converging or di-converging orientations of the rolling surface in relation to the lateral surface of the drum can be realized.
- different pressing forces of the segments on the rolling surface can be realized by adjusting the distance of the rolling surface.
- the manipulation unit can also comprise an abrasive shaping unit, by means of which the shape of the segments can be subsequently changed and reworked by removing material in the area of the cut surface.
- the manipulation unit can also comprise a laser processing unit.
- the proposed solution allows the segments to be reworked very precisely and selectively.
- the manipulation unit comprises a moistening unit, by means of which the cutting edge of the cutting knife can be moistened before the cutting process and / or the segment on a cutting surface after the cutting process.
- a moistening unit by means of which the cutting edge of the cutting knife can be moistened before the cutting process and / or the segment on a cutting surface after the cutting process.
- Cutting knives alternatively also take place after the cutting process via a downstream moistening unit, which is upstream of a forming unit.
- the humidification unit is preferably upstream of an abrasive or non-abrasive molding unit arranged so that the
- Cut surface is moistened by the post-processing, in particular by the molding unit.

- FIG. 12 shows a drum with a segment and a laser processing unit.
- the cutting unit 32 has a cutting knife which has a cutting edge which is oriented such that it cuts the strand over the entire cross section.
- the cutting knife can either make a rotational movement to the strand, as e.g. is the case with the knife carrier described in the introduction, or the cutting knife can be designed to be stationary, and the strand is moved to the cutting edge, as is e.g. is the case when cutting the endless strands on a drum 19 shown in FIG.
- the strand can e.g. be formed tubularly from a cellulose material with a thickness of approx. 200 g / m 2 and thus has a comparatively high cutting resistance.
- This high cutting resistance leads to the fact that on the cutting surfaces 3 and 4 of the segments 1 and 2 on the entry side of the
- Cutting knife a slight ridge 5 and 6 directed towards the radially inner side and a slight ridge towards the radially outer side is formed on the exit side of the cutting knife.
- the ridges 5 and 6 directed towards the radially outer side are particularly disruptive since, in the finished product, this leads to an outward elevation would lead. Contrary to the knowledge that this outer ridge 5 and 6 is annoying, this is consciously accepted here for realizing a high cutting speed, and a manipulation unit described below is provided, with which the ridge 5 and 6 is subsequently actively removed.
- the cut surfaces 3 and 4 are understood here to mean the end faces and the adjacent peripheral sections, which together with the end faces form the circular edge of the cut surface.
- the manipulation unit can be formed by one or more of the following units, a non-abrasive shaping unit shown in FIGS. 2 to 7 and 10 and 11, an abrasive shaping unit shown in FIGS. 8 and 9, a laser processing unit 30 shown in FIG or a humidification unit.
- the non-abrasive molding unit is shown in FIGS. 2 to 7 and 10 and 11, an abrasive shaping unit shown in FIGS. 8 and 9, a laser processing unit 30 shown in FIG or a humidification unit.
- the non-abrasive molding unit is shown in FIGS.
- hood-shaped cone 7 with an inner cone 8, which is dimensioned such that it extends from an outer radius that is larger than the outer diameter of the segments 1 and 2 to an inner radius that is smaller than that Outside diameter of segments 1 and 2 is.
- Cone 7 is coaxial to the cutting surface 3 for reworking the cut surface 3 and for removing the burr 5. As a result, the ridge 5 is displaced radially inwards.
- the segment 1 can be formed from a solid material or as a tubular body.
- a similar cone 7 can be seen in FIG. 4 as a non-abrasive molding unit, which additionally has an inner one axially projecting dome 9 with a conical outer cone 10 arranged thereon.
- the segment 1 is formed here as a tubular body and has a cavity in which the cone 7 with the dome 9 for finishing the
- Cutting surface 3 retracts.
- the outer cone 10 forms during the
- FIG. 5 shows a further alternative embodiment of a non-abrasive shaping unit which is formed by a trigger element 11 which can be moved axially parallel to the longitudinal axis of segment 1 and which is shaped and arranged in such a way that it moves axially over the ridge 5 drives away and deforms the ridge 5 back. So that the segment 1 does not move axially, a stop 12 is provided, on which the segment 1 with the
- a second, counter-moving pulling element 11 can also be provided, provided that a ridge 5 also has to be reworked on the opposite edge of segment 1, as is the case, for example, in the case of segments 1 cut out in the middle of a strand with two cut surfaces 3.
- 6 is another example of a non-abrasive
- Recognition molding unit which is formed by a clamp 13 with two clamping arms 14 and 15 and a radially inner axially projecting mandrel 18.
- the clamp arms 14 and 15 have at their ends radially inwardly directed projections 16 and 17, which are aligned and arranged such that they are directed to a clamping position on an end portion of the dome 18.
- the clamp 13 is inserted for finishing the burr 5 with the mandrel 18 with pivoted outwardly Klemmar men 14 and 15 in the end portion of the tubular section 1 in this case.
- the mandrel 18 forms an abutment, similar to the dome 9 in FIG. 4, and prevents the ridge 5 from buckling radially inwards when deformed.
- the cone 7 provided in the exemplary embodiments of FIGS.
- the clamp 13 that can be seen in the exemplary embodiment of FIG. 6 can also perform a rotary movement to the longitudinal axis of the segment 1 during the reworking process, as a result of which the ridge 5 both in axia - 1 and in the radial direction is formed and pushed away.
- FIG. 7 shows a further alternative embodiment of a non-abrasive shaping unit in which the segments 1 are held in receptacles which are provided on a lateral surface of a drum 19 which can be driven to rotate.
- the recordings are aligned so that the segments 1 are parallel to the axis of rotation of the Drum 19 aligned longitudinal axes are arranged.
- a guide 20 is provided with a curved rolling surface 27 which is concentric with the axis of rotation of the drum 19 and on which the segments 1 are guided during the rotation of the drum 19.
- the rolling surface 27 of the guide 20 can, as can be seen in the right-hand illustrations of FIG. 7, have different shapes. For example, it can have an excess width 24 that is provided in relation to the length of the segments 1, so that a pressing force can be exerted on the segments 1 over the entire length, and the ridge 5 by the
- Rolling surface 27 is flattened. Furthermore, the guide 20 can also perform a directional oscillating transverse movement 23 in the direction of the longitudinal axes of the segments 1, through which the ridge 5 is laterally displaced. Alternatively, the rolling surface 27 can also have a radius 22 which laterally and inwardly projects beyond the cut surface 3 and through which the ridge 5 is shaped inwardly. Furthermore, a brush 21 can also be provided on the rolling surface 27, by means of which the ridge 5 is brushed elastically inwards.
- FIG. 8 shows an embodiment of an abrasive shaping unit in which the ridge 5 is moved by a mechanical rotary tool 25 e.g. in the form of a grinding wheel or a milling cutter.
- the rotary tool 25 is stationary in a predetermined orientation and
- the rotary tool 25 ro tiert about a parallel to the axis of rotation of the drum 19 aligned axis of rotation in the same direction, whereby the processing speed of the surface of the segment 1 he can be increased, as this increases the relative speed of the work surface to the segments 1.
- the ridge 5 can thus be reworked in a very small arc section of the rotary movement of the drum 19.
- the working surface of the rotary tool 25 can be differently aligned or profiled differently depending on the shape, orientation and size of the burr 5 to be reworked.
- FIG. 9 A further form of an abrasive shaping unit can be seen in FIG. 9, in which a fixed blade 33 oriented according to the burr 5 to be removed is provided. The segments 1 are guided past the blade 33 during the rotation of the drum 19 with the ridge 5, and the ridge 5 is actively separated.
- FIG. 10 shows a further alternative embodiment of a non-abrasive shaping unit in the form of a static guide surface 26 with a rolling surface 27 arranged concentrically to the axis of rotation of the drum 19 and at a substantially constant distance. Furthermore, one in
- the cutting unit 32 is provided, which cuts the strand into two or more segments 1. Furthermore, the rolling surface 27 has a starting bar 32 on the entry side, which protrudes into the transport path of the segments 1.
- the rolling surface 27 is arranged at a distance from the base of the receptacles of the drum 19, which is the diameter of the segments 1 minus 0.2 to 1.5 mm. wearing. The distance thus deliberately has an undersize compared to the diameter of the segments 1, which is further reduced by the start bar 32 on the entry side. Due to the starting bar 32 and the selected distance, the segments 1 are forced to roll on the rolling surface 27 due to the rotary movement of the drum 19. During this rolling movement, the segments 1 are compressed due to the undersize and pressed against the rolling surface 27, so that the ridge 5 pushes itself away. In this case, a guide track 31 with a length L of
- Segments 1 corresponding width B may be provided, in which the segments 1 roll out laterally during the deformation movement.
- the guide surface 26 can also be seen on a rotatably mounted roller with a corresponding profiling, as can be seen in the right-hand illustration in FIG. 10.
- a further alternative embodiment of a non-abrasive shaping unit can be seen in FIG. 11, in which the guide surface 26 is again arranged on a rotatably driven roller that is pressed against the outside of the segments 1.
- a mandrel 28 inserted into the segment 1 is provided as an abutment, so that the cut surface 3 with the ridge 5 is pressed together in a gap between the roller and the mandrel 28 and displaced into a tubular shape.
- FIG. 12 shows a further embodiment of the manipulation unit in the form of a laser processing unit 30 and egg ner segments 1 for a rotational movement about their longitudinal axes driven roller 29.
- the laser processing Unit 30 is aimed at the lateral edge of the segments 1 with a laser beam and thereby cuts off the ridge 5.
- the manipulation unit can have a moistening unit, with which the cut surface 3 is moistened before the post-processing.
- This humidification unit can e.g. be formed in the form of a liquid supply, through which the cutting knife or plungers dip before the cutting process, so that the moisture already during the cutting process through the
- Cutting knife is introduced into the cutting surface 3. If this is not possible, the cut surface 3 can also be actively applied after the cutting process. It is important here that the cut surface 3 is moistened before the post-processing so that the moisture has the positive effect of the increased elasticity of the cut surface 3 for the post-processing.
- the strand can also be moistened in the area of the cutting area of the cutting knife before the cutting process, wherein moistening of the strand outside the cutting area should be avoided.
- the manipulation unit can comprise one or more of the units described. So it is e.g. it makes sense to combine a non-abrasive molding unit with an upstream moistening unit. Furthermore, a non-abrasive one
- Molding unit can be combined with a downstream abrasive molding unit, e.g. to remove an abrasive residual burr not deformed back by the non-abrasive shaping unit, whereby the shape accuracy of the segments 1 can be further improved.
- the manipulation unit is preferably upstream of a combination with respect to the transport direction T of the segments 1.
- tion unit and a wrapping unit arranged so that the reworked segments 1 with the qualitatively improved surface in the combination unit with the other segments 1 combined and connected to each other by the wrapping strip to a finished product.
- the solution according to the invention can also be used.
- the cut surface of the finished product can also be reworked, whereby the surface quality of the finished product can also be improved.
