Definitions

  • the invention relates to a device for producing a strand of sheet material, comprising a separating device which is adapted to separate a flat web into a plurality of strips. Furthermore, the invention relates to a method for producing a strand of sheet material, in which a flat web is separated with a separating device in a plurality of strips.
  • a device for producing a strand of reconditioned tobacco material for example, from the DE 1 954 036 out.
  • a flat sheet of reconditioned tobacco material is cut into parallel strips using a disc cutter. These strips are gathered into a strand and surrounded with an outer covering.
  • the wrapped strand is cut into pieces of predetermined length so that a rod-shaped article, such as a cigarette, can be made.
  • the cooperating circular blades are in direct contact with each other and cut the material at the point to be cut by sliding the two blades directly against each other.
  • the object of the present invention is to specify an improved device and an improved method for producing a strand.
  • a device for producing a strand of sheet material comprising a separating device which is adapted to separate a flat web into a plurality of strips, wherein the device is formed by the fact that the separating device has a first and a cooperating second Roller, wherein the lateral surfaces of the rollers in the axial direction alternately circumferentially closed circumferential grooves and elevations and engage in a range of action, the elevations of the first roller in the grooves of the second roller and the elevations of the second roller in the grooves of the first roller, wherein the Separating device is adapted to separate immediately adjacent strips along a predetermined separation line in the effective range of each other by the flat sheet is stretched across the parting line so strong that it tears along the dividing line, wherein the device further comprises a strand forming unit Asst, which is adapted to form a strand of the plurality of strips.
  • the first and the second roller are not in contact with each other in the effective range.
  • the flat web is not cut along the dividing line by the interaction of two blades but torn by overstretching defined.
  • the flat web is separated in a defined manner along the at least one parting line, but no cutting process takes place.
  • the flat track is locally overstretched so much that it tears apart in a defined manner and advantageously has an open structure at the top Fracture edge of the strips arises. Because of this open structure, the strips are for example more suitable to take in additives or even, for example, when heated, deliver.
  • the flat web is, for example, flat reconditioned tobacco material, a PLA film or a paper web.
  • the strand made from the plurality of strips of reconditioned tobacco material in the strand forming unit is, for example, a strand from which smoking products are later produced. Due to its ability to absorb and release additives well, the string of reconditioned tobacco material is particularly suitable for so-called "heat-not-burn" tobacco products.
  • PLA film is used as the material for the flat web, for example, a cooling element or the like can be produced from the strand.
  • the flat web is a paper web. From it, for example, a filter element or a spacer can be made.
  • Another advantage of the separation device according to aspects of the invention is the significantly reduced wear of the separation device compared to conventional cutting devices in which the blades used to sever the flat web are in direct contact with each other and slide off each other during the cutting process.
  • the cooperating rollers of the separator are not in mechanical contact with each other, so they do not touch during operation of the device. For this reason, no or a significantly reduced material abrasion or wear takes place on the two rollers. This allows much longer and improved service life of the rolls compared to conventional solutions.
  • the grooves and elevations of the first roller are all the same dimensioned, as are the grooves and elevations of the second roller. All present on the respective roller grooves and surveys are therefore in Axial direction of the roller of equal width and have the same depth in the radial direction. The same applies in particular to the surveys. It is further provided in particular that the elevations of the first roller and the elevations of the second roller in the radial direction are of different heights.
  • the strips lying on one roller in the grooves can be pressed from the elevations of the other roller to the bottom of the grooves. By this pressure, the promotion of the flat web can be effected.
  • the strips present in the opposing grooves lie freely on the end faces of the elevations.
  • the two rollers can be designed to be similar and complementary to one another. So an optimal interaction between the rollers is possible.
  • the separating device is therefore particularly adapted to produce a plurality of strips from the flat web, wherein the strips produced all at least approximately the same width.
  • the rollers of the separating device can be set up in particular so that strips with different widths are produced. It can be provided both regularly different and irregularly different strip widths. For example, each second groove and cooperating with this elevation in the axial direction are twice as wide as the adjacent grooves or elevations. So regularly different widths stripes can be produced. It is thus possible to produce strips of different widths or to provide a pattern.
  • the width of the strips is measured transversely to a longitudinal extension direction of the strips and in a strip plane.
  • the strip plane should be that plane in which a smooth strip of reconditioned tobacco material leaving the separator extends.
  • the elevations and the grooves are interconnected by radially extending flanks and the dividing line extends between a first flank of the first roll and a second flank of the second roll.
  • the elevations and the grooves are at least approximately rectangular in cross section.
  • the cross section of the elevations and grooves is considered in a plane in which lie the two axes of the two rollers.
  • a first flank is understood as meaning an flank extending between a protrusion and a groove or between a groove and a protrusion on the surface of the first roll.
  • a radially extending flank is to be understood as an area which lies in a plane defined by the radius of the roller.
  • the device is further developed in that the separating device is arranged for separating a flat web with a predetermined material thickness, wherein between the first and the second flank an axial gap is present, which is one to three times a value of the predetermined material thickness Flat track amounts.
  • the specified axial gap has proven to be particularly suitable to ensure an efficient separation process of adjacent strips.
  • the surface of the rollers may be described as comprising a plurality of disks spaced apart from one another.
  • the distance between the discs is the respective axial Width of the groove.
  • the measured in the axial direction width of the discs corresponds to the respective width of the surveys.
  • On the rollers is a periodic array of parallel aligned discs whose distances are all the same.
  • the spacing of the elevations is set up such that strips with a strip width of at least approximately 0.8 mm to 10 mm can be produced from the flat web. This value, for example, also corresponds to the axial distance of adjacent elevations.
  • the device is further developed in that the separating device is arranged for separating a flat web having a predetermined material thickness, wherein a distance measured in the radial direction of the rolls between an upper side of the elevations of the first roll and an upper side of the elevations of the second roll represents the fifth roll. is up to ten times a value of the given material thickness of the flat web.
  • the two rollers are aligned with each other so that they intermesh by five to ten times the value of the predetermined material thickness of the flat web. This ensures that the flat web is overstretched in a direction perpendicular to its surface by five to ten times its material thickness.
  • the specified value ensures that the flat web is stretched beyond the value for the breaking elongation so that a separation of adjacent strips takes place reliably.
  • the device comprises a first embossing device arranged downstream of the separating device and configured to impress the strip in a longitudinally, for example periodically, variable structure, which rises from the strip plane.
  • the periodically variable structure is, for example, wave-shaped or zigzag-shaped.
  • the first embossing device can also be referred to as an "out of plane” embossing device, since the embossed structure rises out of the stripe plane and thus in this sense "out of plane”.
  • the embossed structure ensures that the strips are made in the Stake strand against each other. In other words, in the strand comprising a plurality of strips of reconditioned tobacco material, there is an interaction between the individual strips. These can not move too easily in the axial direction of the strand against each other, which prevents unwanted effects such as a head loss.
  • the grooves and elevations of the rollers are designed to be variable.
  • the strips produced have a variable structure in the strip plane, ie in this sense "in plane".
  • Such an in-plane structure has a similar effect to the aforementioned out-of-plane structure.
  • the strips interact with each other in the manufactured strand so that their slidability in the longitudinal axial direction is reduced. This property is advantageous both for the product produced and for the processing of the strand. For example, it reduces the likelihood that individual strips will be pulled out of it when cutting the strand.
  • the elevations of the rollers in their outwardly directed end faces, have a circumferential groove-shaped recess in the circumferential direction.
  • the elevations of the rolls viewed in a cross section in which the axial direction is located, are set back in sections in the region of their end faces, ie in the direction of a smaller radius.
  • the groove provided in the end faces of the elevations is, for example, V-shaped, U-shaped, semicircular or has another suitable shape.
  • the radially encircling grooves extend, for example, on an area between 60% and 80% of the total End face, so that a remaining maximum contact surface of the strips is between 20% and 40%.
  • the reduction of the bearing surface has an advantageous effect on a tendency dependent on the web material tendency to adhere to the end faces of the surveys.
  • the grooves extend to almost the entire end face of the elevations. If the grooves are then configured in cross-section, for example, V-shaped, the result is, ideally, only an investment of the strip along two lines (in cross-section of two points). Thus, a minimal contact surface of the strips can be achieved on the front sides of the surveys.
  • a reduction in the contact area and the consequent decreasing tendency of the material to adhere to the end faces of the elevations is advantageous, above all, for the processing of reconditioned tobacco material, which has a high glycerol content and therefore, in part, has a rather sticky consistency.
  • the device comprises a bending device arranged downstream of the separating device and arranged to strip the strip produced by the separating device with a structure, in particular periodically present in the strip plane, at least in regions in the region of its extrema lying in the strip plane kink a remaining surface part of the strip plane out.
  • the kinked extremes which are an example of a wave cut to the shaft tips or a zigzag, for example, the outer corners of the teeth, ensure that the strips in the strand even more strongly interlock.
  • the extremes can be bent or bent at least approximately 90 ° relative to the strip plane. It is also envisaged that successive extremes, for example, be alternately bent upwards and downwards from the strip plane, bent or folded.
  • the device between the first embossing device and / or the bending device and the strand forming unit comprises a selective deceleration device which provides at least one transport path and a delay path with a conveying path which is longer in relation to the transport path, wherein there is also a grouping device arranged for this purpose in that the plurality of strips are divided into at least a first group and a second group, wherein in the delay device the first group is guided along the transport path and the second group along the delay path, and wherein the delay device is further adapted to the first and the second Group merge downstream of the transport and delay line again to a common strand and provide this common strand of the strand forming unit.
  • phase shift between the two groups of strips can be achieved.
  • the strips of different groups are pulled over rollers or bolts with different diameters, so that the intended path difference can be adjusted.
  • the phase shift achieved in this way is, for example, half the period of the embossed "out of plane” structure or the "in-plane” structure present as a result of the separation process.
  • an extremum of a strip of the first group meets an equal extremum of the strip of the second group, whereby a particularly large volume gain and thus an increased filling force can be realized.
  • the device is designed, for example, such that adjacent strips are alternately assigned to the first and the second group. It is further provided, for example, that the device is set up in such a way that a multiplicity of groups are provided, with two or more delay lines of different lengths being provided starting from a number of three groups. By providing different phase shifts between the individual groups, the filling power and the associated gain in volume can be further improved.
  • the device comprises a second embossing device arranged downstream of the separating device and configured to impress the strip on a structure which varies transversely to its longitudinal direction and which rises from the strip plane.
  • the strip is impressed in the longitudinal direction of a V-shaped, W-shaped, channel-shaped or similar structure, which rises from the strip plane.
  • a V-shaped, W-shaped, channel-shaped or similar structure which rises from the strip plane.
  • the device is formed by a pulling device, in particular a draw roller pair, which is integrated in a transport path of the plurality of strips downstream of the separating device and upstream of the strand forming unit.
  • a traction device is particularly advantageous if reconditioned tobacco material is used as the web material.
  • Reconditioned tobacco material is quite different in its properties, but many flat sheets of reconditioned tobacco material are rather sticky. After such a web material has been separated into individual strips, it is sometimes difficult to pull the individual strips off the rollers.
  • a pulling device ensures that the individual strips are continuously removed from the rollers of the separator. This can on the one hand be avoided that too strong tensile forces it comes to a tearing of the strip and on the other hand adhere to the rollers due to low tensile forces the individual strips.
  • a pulling device is the means of choice to continuously strip the strips one at a time from the rolls, but not to exert excessive forces on the material, so that there could be negative elongation effects.
