Abstract

The invention relates to a filter tow bale (2) of compacted filter tow and is characterized in that the filter tow bale (2) comprises at least two separate filter tow strips (1, 1 '), which are arranged together in layers.

Description

  • The The present invention relates to a filter tow bale having the features of the preamble of claim 1, an apparatus and a method for producing a filter tow bale and a filter tow Strips.
  • One Filter tow bales of the type mentioned is, for example manufactured and sold by the applicant.
  • to Production of cigarettes are used in a filter Strip or endless strand of crimped cellulose acetate fibers, the so-called filter tow. In the preparation of from Filter Tow are spun filaments of cellulose acetate in a stuffer box crimped, wherein the imprinted Curling structure fixed when passing through a dryer becomes. After the filter tow to a constant final moisture was brought, this is loose in several meters high pitchers inserted in regular patterns. The easygoing Tow layer is then baled to a filter tow bale compacted and final packed, for further processing is provided for filtering.
  • A detailed explanation of the manufacturing process of Filter Tow is in the article CA Filter Tow for Cigarette Filters, Paul Rustemeyer, Macromolecular Symposia 208 (2004), 267-291 disclosed.
  • The Processing of filter tow to filter rods occurs on a filter rod machine on which the filter tow in a processing part as much as possible, to its maximum filling power then to the format of the future Cigarette filter gathered and wrapped in paper becomes. To buff the filter Tows this is powered by compressed air Spreader nozzles pulled apart and through a system of drafting rollers with threaded or screwed surfaces stretched. Thereafter, the spread filter tow becomes a triacetin spray box supplied in which dissolved the acetate surface and sticky. In the format part of the filter rod machine is the filter tow band gathered and on the cross section of the future Filter rod compressed. The filaments stick together and form a three-dimensional spatial network structure with the the finishing and the consumer desired Filter hardness.
  • To increase productivity, it is for example from the DE 43 20 317 , which is also due to the applicant, known to produce filter rods on double filter rod machines, in which two filter tow strands are processed in parallel and synchronously.
  • For a constant quality of the filter rods On the one hand, the filter tow strips similar properties and on the other hand as evenly as possible both run off the filter tow bale, as well as run into the double filter rod machine.
  • Of the Invention is based on the object of specifying a filter tow bale the most even running possible allows for filter tow strips and for use in a double filter rod machine is suitable. Furthermore, a device and a method of making a filter tow bale as well a filter tow strip for such a filter tow Bales are specified.
  • According to the invention this task with regard to the filter tow bales through the object of claim 1, with regard to the device through the article of claim 10, with regard to the method by the subject matter of Claim 18 and with regard to the filter tow strip through the Subject of claim 21 solved.
  • The Invention has the advantage that stripes through the separate filter tow spontaneous voltage rises of the filter Tows on the double filter rod machine largely avoided, causing the associated density variations be minimized in the manufactured filter. Furthermore the filters Tows can be created and stored at the same time, so that their properties are similar or identical, what in the production on the double filter rod machine to a improved filter uniformity of both strands leads. In addition, due to the identical run lengths the two filters Tows reduced production waste. at different filter tow lengths, for example, conditionally by draining two different filter tow bales, comes it through the process of threading a new filter Tows to increased waste and machine downtime. The bale according to the invention allows further that different filters Tows are inserted in the bale, so that, for example, filter rod machines for special filters can be supplied with two different tows.
  • In a preferred embodiment, the at least two filter tow strips are chaotically piled in insertion paths, in particular in substantially parallel paths or in acute-angled zigzag paths in the bale. This embodiment is based on the general idea to arrange the two filter tow strips directed in the bale, wherein the two strips a Forming web patterns. The web pattern can be constructed, for example, from essentially parallel webs or from acute-angled zigzag webs. The two filter tow strips are chaotically heaped along and within the webs, respectively. This means that in this embodiment, the chaotically piled filter tow strips each have a preferred direction or a dominant direction, which runs in batches in the web. The tracks thus each form imaginary lateral boundaries within which the chaotically heaped filter tow strips are arranged. Due to the web-like arrangement of the layered filter tow strips, the flow behavior of the strip is advantageously influenced by the bale.
  • The Both filter tow strips can bale in the filter tow be arranged side by side in substantially parallel paths and have a distance of at least 0 cm and at most less than half the bale width. At a distance from 0 cm the Filter Tow streaks or the webs, within which the filter tow strips are arranged, immediately to each other. The distance between the parallel tracks or the parallel stripes can be> 0 cm and less than the maximum be half bale width. In a particularly preferred embodiment at least two filter tow strips at least partially overlapping arranged and have an overlap area. The overlap area may have an overlap degree of 100% to> 0%. subregions This overlapping area is also possible. At a degree of overlap of 100%, the Filter Tow stripes are or the webs within which the filter tow strips are arranged are completely on top of each other.
  • there The filter tow strips can be stored in such a way in the bale be that the strips are arranged alternately top and bottom. In this case, the strip arranged in a lower strip at the end of the bale a turning point reversal in such a way that the first below arranged stiffeners after the turning point reversal on the returning track is arranged above. This results in a self-regulation that prevents the stripes from leading because the lower of the two strips has a higher voltage has, if this wants to overtake the upper strip. by virtue of the superposition of the strips takes the lower the top strip with. After the turning point when running back the other strip above, then turn the lower strip has the larger voltage and the top arranged Strip takes along. Overall, this results in self-regulation in the Drain the two strips from the bale.
  • Further preferred embodiments of the invention Filter tow bales are specified in the subclaims.
  • in the With regard to the device for producing a filter tow bale the invention is based on the idea of an insertion device, which cooperates with a pot for storing the filter Tows, as well Means for simultaneously producing or providing at least to provide two separate filter tow strips. Here are the separate filter tow strips through a single or double insertion device Layered in layers in the pot. In the context of the invention Method for producing a filter tow bale, in particular for processing in a double filter rod machine at least Two separate filter tow strips made at the same time or provided, layered in a jug and stored pressed in bale shape.
  • With the device according to the invention or the invention Process can be in a simple manner the inventive Make filter tow bales.
  • preferred Embodiments of the invention Device or the method according to the invention are given in the subclaims.
  • One for a filter according to the invention tow bales especially suitable filter tow strips of cross-linked and crimped Filaments has at least two partial strips, wherein the partial strips at least partially, in particular completely overlapping arranged and in the overlap area by applying a mechanical surface force are connected. By the slight connection between the two partial strips, which incidentally be considered as separate partial strips within the meaning of the invention, The flow behavior of the filter tow strip is removed from the bale positively influenced.
  • preferred Embodiments of the invention are in the subclaims specified.
  • The Invention will be described below with reference to exemplary embodiments with reference to the attached schematic drawings explained in more detail. Show in it
  • 1 a schematic cross-section of two filter tow strips in different combinations A-E in the area of the insert;
  • 2 a filter tow bale according to the invention during the passage of the filter tow strip according to a preferred embodiment;
  • 3 a filter tow according to the invention Bales during drainage of the filter tow strips according to another preferred embodiment; and
  • 4 a schematic representation of the top of the bale surface, wherein the insertion track of two superimposed filter tow strip is shown.
  • 1 schematically shows different variants A-E for the combination of two filter tow strips 1 . 1' , where the combination of the two filter tow strips 1 . 1' before or during insertion into a jug. The filter tow located in the pot then becomes a double tow bale 2 pressed.
  • In the 1 shown combined filter tow strips are located in the insert (not shown), in particular between the feed rollers of an insert. This illustration is chosen for clarity, since the arrangement of the two filter tow strips 1 . 1' It becomes especially clear there in relation to each other. The arrangement of the two filter tow strips 1 . 1' in the insert determines the arrangement of the two strips 1 . 1' in the filter tow bales 2 , This means that the strips arranged in parallel in the insert 1 . 1' according to illustration A in the filter tow bale 2 are also arranged substantially parallel or in parallel paths. The superimposed stripes 1 . 1' according to illustration B are also arranged one above the other in the bale or are stored in superimposed webs.
  • The filing of the filter tow strips in the pot and thus the arrangement of the filter strips in the pressed bale takes place in layers. The webs are arranged in a predetermined pattern resulting from the arrangement of the filter tow strips 1 . 1' in the depositor and the guide of the filter tow strips 1 . 1' when inserting results. Inside the tracks are the filter tow strips 1 . 1' each arranged chaotically heaped. The tracks follow a given pattern. By way of example, the webs are arranged parallel, completely overlapping or partially overlapping. The arrangement of the filter tow strips 1 . 1' or the corresponding tracks is based on the variants A-E according to 1 explained in more detail.
  • According to variant A in 1 are the two filter tow strips 1 . 1' arranged at a distance next to each other. The Stripes 1 . 1' are aligned parallel to each other, with the distance along the two strips 1 . 1' remains essentially constant. The filter tow strips 1 . 1' can have a distance of 0 cm to each other so that the filter tow strips 1 . 1' touch directly. It is also possible that the distance between the two filter tow strips 1 . 1' half the width of the Double Tow bale 2 corresponds, so that each one filter tow strips 1 . 1' one half of the Double Tow Bal lens 2 assigned. Also, all distance values between 0 cm and half the bale width or less than half the bale width are possible, in particular in the range between 0.5 cm and 20 cm, between 5 cm and 20 cm or between 5 cm and 10 cm.
  • According to variant B, the two filter tow strips 1 . 1' completely overlapping each other in length. In this way forms over the entire strip width a light connection between the two filter tow strip 1 . 1' made a particularly uniform, synchronous draining of the filter tow strips 1 . 1' from the double tow bale according to the invention 2 allows. The two filter tow strips 1 . 1' can also, as shown in variant C, be partially overlapping combined with each other, wherein the degree of overlap of the two filter tow strips 1 . 1' between 0% (variant A) and 100% (variant B) may vary. Even if by pressing the superposed strips 1 . 1' makes a light connection, the strips are in the context of the invention as a separate strip 1 . 1' considered.
  • According to a preferred variant D, the two filter tow strips 1 . 1' arranged completely overlapping each other and folded in half lengthwise, so that the combined strip consists essentially of four filter tow layers. After inserting the combined strip with this variant by pressing the Double Tow bale invention 2 not just a slight connection between the two filter tow strips 1 . 1' achieved, but also a slight connection of the two longitudinal halves of the first filter tow strip 1 among themselves. By folding the combined strip is also achieved that from relatively wide filter tow strips 1 . 1' a relatively narrow and easy to handle combined strip is formed. This advantage also offers variant E, with the two filter tow strips 1 . 1' are folded into one another, ie the first filter tow strip 1 points with the second filter tow strips 1' essentially a degree of overlap of 50%, with the non-overlapping portion of the first filter tow stripe 1 is folded, leaving this on the overlapping part of the second filter tow strip 1' , in particular with the overlap area congruent, rests. The outer, non-overlapping part of the second filter tow strip 1' is also folded so that it strikes on the folded first filter tow 1 to come to rest. According to variant E, the connecting surface between the two filter tow strips 1 . 1' especially large, so that a relatively intense and yet easy to solve Verbin Formation between the two filter tow strips 1 . 1' forms and thus to a particularly advantageous, uniform and synchronous running of the combined strip or the two filter tow strip 1 . 1' from the double tow bale according to the invention 2 leads.
  • 2 and 3 each show a Double Tow bale according to the invention 2 , with the two filter tow strips 1 . 1' according to variant A from 1 are arranged side by side. A bale 2 with superimposed stripes 1 . 1' or lanes according to variant B would accordingly 2 be handled. The distance between the two filter tow strips 1 . 1' in 2 is less than half the bale width, while the distance between the two filter tow strips 1 . 1' in double tow bales 2 according to 3 exactly equal to half the bale width.
  • Furthermore, in the 2 and 3 schematically a drain device 3 with guide rings 4 shown over the first filter tow strip 1 as well as the second filter tow strip 1' from the bale 2 run and a double filter rod machine (not shown) are supplied. The two filter tow strips 1 . 1' are each meandering in a plane in Double Tow bales 2 arranged, with the distance between the two filter tow strips 1 . 1' is substantially constant to each other. The embodiment according to 3 differs from 2 insofar as each one filter tow strips 1 . 1' one half of the double tow bale 2 assigned. When inserting the filter tow strip 1 . 1' in the bales 2 For example, the first filter tow will strip 1 in the middle of the bale 2 Beginning meandering towards an outer edge inserted in parallel paths, while the second filter tow strip 1' Starting from an opposite outer edge, parallel to the first filter tow strip 1 meandering toward the center of the Double Tow bale 2 is inserted. This means that the two first laid webs have a distance to each other, which corresponds to half the bale width. Because the two filter tow strips 1 . 1' are arranged parallel to each other, the other respective corresponding, parallel tracks are spaced from each other by the amount of half the bale width.
  • In general, a filter tow bales 2 from compressed filter tow at least 2 separate filter tow strips 1 . 1' , which are arranged in layers, preferably in the same layer. A filter tow bale with exactly two filter tow strips is also known as a double tow bale. Generally, the strips are each arranged together, in particular in pairs in a layer and together form a plane. In this case, the surface is considered as a plane, which is swept once in the context of a lye cycle by the filter tow or the associated depositor. Within this level, it is possible that due to the accumulation of the individual filter tow strips, there is a local accumulation of several filter tow sections on top of each other, but they still lie in the plane swept over each lay cycle.
  • The filter tow bale is constructed from a plurality of corresponding layers or levels arranged one above the other, which are formed in each case by jointly depositing the two filter tow strips in a jug with subsequent pressing of the strips. The stripes over several layers are ideally formed throughout the entire bale throughout. The arrangement of the filter tow strips is carried out according to a predetermined pattern, which may vary depending on the process engineering requirements. The pattern results from the arrangement of the webs in which the filter tow strips are deposited in the pot and which are also in the bale after pressing 2 find again. The webs correspond to the preferred directions of the filter tow strips, which are chaotically piled within the webs or stored statistically rearranged. An example of a corresponding accumulation trace is in 4 shown. It can be seen that two filter tow strips 1 . 1' (dotted line / solid line) are arranged substantially one above the other. The superposition of the filter tow strips 1 . 1' does not mean that the two pathways are exactly superimposed. Rather, results when depositing the two filter tow strips 1 . 1' in the 4 shown accumulation track, the two filter tow strips 1 . 1' have a common preferred direction. The insertion paths resulting from this preferred direction are in accordance with the example 4 arranged one above the other and have a degree of overlap of 100%. At lower degrees of overlap, for example, at a degree of overlap of 50%, the two webs are within, within which are the clumping traces of the two stripes 1 . 1' are arranged, offset from each other so that the accumulation tracks overlap substantially only half. It is clear that in the case of statistically rearranged aggregation there are greater or lesser degrees of overlap. However, it is important that, for example, at a Überlap pungsgrad of 50%, the accumulation tracks or tracks at least predominantly run so that they lie in half about each other.
  • The arrangement of the webs or accumulation marks in the bale is essentially determined by how the filter tow strips 1 . 1' in the insert, in particular in the rollers of the insert are arranged. This arrangement is in the variants A-E according to 1 shown. For example, results in variant C (about 50% degree of overlap) a corresponding arrangement of the accumulation tracks or tracks in the compressed bale.
  • Next the parallel arrangement of the tracks (overlapping or side by side) it is also possible to arrange the tracks divergently such that the webs are apart along their longitudinal extent to run. In addition, an acute-angled zigzag arrangement the inlays possible.
  • The invention also includes bales with more than two separate filter tow strips, for example with 3 or 4 strips. The parallel arrangement of the filter tow strips 1 . 1' means that the webs in which the filter tow strips 1 . 1' are arranged, in pairs directly adjacent or directly next to each other in the bale are arranged. The tracks of the first and second filter tow strips 1 . 1' may be overlapping, directly adjacent, ie arranged on impact or parallel with a distance from each other. Preferably, the two filter tow strips 1 . 1' overlapping arranged in the bale 2 inserted so that they make a light connection.
  • For the simultaneous production or provision of the separate Stripes have different possibilities. It is possible, different independent strips in different independent crimping machines manufacture. Furthermore, different independent Strip produced within a single crimping machine be, with the filter tow strips in the crimping chamber be run with such a large distance that a connection of the strips does not take place. Furthermore, a related Strips are produced, which are subsequently divided into two strips is disconnected. There are various possibilities for this. The separation of the strip can be done either in the crimping machine, after the crimping machine, on the way to the loading device or in the loading device. Because of the separation the strip does not occur in the filter rod machine is avoided that the filter rod machine by the resulting in the separation Fiber fragments is soiled, so that the maintenance intervals of the Filter rod machine can be increased.
  • The simultaneously produced separate filter tow strips by a single and a double, or generally multiple Loading device (not shown) combined stored in the pot. The loading device is with a programmed accordingly Control coupled. The control of the loading device allows the filing of the two filter tow strips in the pot after one given patterns, for example, in superimposed Tracks.
  • The Apparatus for producing a filter tow bale further comprises to the above-described means for simultaneous production a Spinning device for producing filaments, a crimping device for curling the filaments, a dryer and the loading device, the with the pot for storing the filter Tows cooperates.
  • The Separating device can be two transverse to the conveying direction of the Filter tow strip spaced guide rings and a the guide rings upstream in the conveying direction guide ring include. Alternatively or additionally, the separating device comprise at least one separating wedge.
  • Instead of the simultaneous or synchronous production of the separate filter tow strips 1 . 1' For example, a jug may be charged with two separate filter tow strips which are provided in the form of two single bales. The individual bales can be provided for example in the form of broke bales. From the single bales, two strips are withdrawn and transferred together into a jug.
  • From the above description it is clear that the separate filter tow strips 1 . 1' can be produced in various ways, with no restriction as to the number of filter tow strips, but more than two, for example three or four filter tow strips can be made or provided. The particular advantages of the embodiments according to the invention result from the fact that the filter tow strips 1 . 1' put together in layers in the pot and pressed into bales. These filter tow bales have at least two separate filter tow strips which are arranged in batches together in layers.
  • The Insert the filter tow strips in the double tow bales in the Way that the filter tow strips overlap Furthermore, the advantage that the filter tow stiffeners a slight Connect with each other, which by pressing, d. H. caused by the application of mechanical pressure. It has It has been shown that such a loose connection between the Filter Tow strips a particularly uniform and synchronized drainage of the strips from the bale, so that density fluctuations avoided in the manufactured filter strand become. In this respect, a filter made up of partial strips also becomes a filter Tow strip claimed, the relatively low strength the compound is determined by applying it of mechanical pressure on the partial strips, in particular during pressing of the bale is generated.
