Definitions

  • the invention relates to a method according to the preamble of patent claims 1 or 2 and to an apparatus for carrying out the method according to the preamble of patent claim 6.
  • One method is the so-called "classic method", in which the slivers formed on the card are presented to a subsequent wadding machine for further processing.
  • the slivers are fed, for example, in two groups of twelve belts each to a drafting unit of the wadding machine, the slivers being stretched with approximately 1.5 times the draft.
  • the nonwovens released and stretched from the drafting systems are placed on the stretched nonwovens of the second drafting system via a sweeping device.
  • the doubled nonwoven fabric, or fleece for short, that is produced according to this summary is fed to a winding device for forming a lap.
  • the windings formed in this way are brought by a transport device or manually to a sweeping path, on which a plurality of windings, for example six windings, are unwound at the same time.
  • the unrolled cotton webs each run through a drafting system, which causes the material supplied to be warped by about 6 times.
  • the wadding webs released and drawn by the drafting systems reach a conveyor table via a sweeping device, on which all cotton sheets are laid on top of each other or doubled.
  • the wadding web thus formed is transferred to a winding device and rolled up into a roll there.
  • this winding As soon as this winding has a predetermined size, it is taken over by the transport system, which transfers the winding individually or in a winding group to the subsequent combing machine.
  • the high warping of the wadding webs with subsequent doubling applied to this machine results in a high cross-section doubling, as a result of which the band structure in the wadding web cross section almost completely disappears.
  • This structure enables an optimal distribution of the clamping force of the pliers on the cotton in the subsequent combing machine. This is particularly advantageous when processing long stacks in order to provide the fibers with a sufficient retention force in the clamped state during the combing process on the combing machine.
  • This relates in particular to the fibers which are located in the middle area of the cotton to be combed.
  • the slivers emitted by the cards are fed to a section on which they are doubled, then stretched and brought together to form a sliver.
  • the slivers formed on the lines are presented in groups to a subsequent sliver duplicating machine.
  • the individual groups of fiber slivers are each fed to a drafting system and subjected to a delay of approximately 1.5 times, depending on the sliver number.
  • the fiber slivers emitted and drawn by the drafting devices form a so-called fiber fleece, which is pressed downwards onto a sweeper Feed table is dispensed.
  • the nonwovens released by the respective drafting system are laid one on top of the other or relined.
  • the doubled non-woven fabrics are transferred via calender rolls to a winding device in which one of the windings required for the combing machine is produced. As described in the first case, this winding is ejected and transferred to the combing machine individually or in groups by means of appropriate transport devices. In the machine described, a total of approximately 32 to 48 cans with slivers can be placed on the infeed table.
  • the second method shown does not require an additional wadding machine to form an intermediate lap, which must then be presented to a sweeping section. This means that no additional transport device is required to transfer these intermediate windings from the wadding machine to the sweeping section.
  • an additional section passage is connected upstream, on the one hand to maintain the correct hook position of the fibers in the fiber sliver and on the other hand to obtain a good mixing and uniformity as well as a parallelization of the fibers of the sliver presented. This is achieved in particular through the tape doubling undertaken in the route passage.
  • the advantages of the second method compared to the classic method are, in particular, the high productivity due to the fewer and simpler transport tasks (can transport instead of winding transport) and thus fast throughput times.
  • a relatively large number of cans can be presented for processing in the second method.
  • reserve tapes can be carried out more easily and quickly than the application of wadding in conventional methods.
  • the object of the invention is now to propose a method or a device for carrying out the method which, on the one hand, enables high productivity in conjunction with a - in cross section - qualitatively homogeneous cotton.
  • the proposed methods and the devices for executing the methods enable the presentation of a large number of cans and the formation of a high-quality cotton cross-section as well as a process shortening and a reduced transport work of the material in connection with a high warping of the fiber slivers directly on the winding-forming machine. This is ensured in particular by the use of two consecutive drafting stages, the nonwovens formed in the first drafting stage then being doubled before they are presented to the second drafting stage. This results in a high cross-sectional duplication, whereby, as with the classic method, the band structure is blurred in the cross-section of the wadding.
  • in groups denotes a certain number of fiber tapes or non-woven fabrics.
  • the failure of one or some of the fiber tapes in the inlet leads to only a slight loss of mass of the cotton web formed.
  • the failure of 5 fiber tapes only leads to a mass loss of approx. 2% of the cotton web formed.
  • the slivers stored on the card in the intermediate store into a second intermediate store, which are presented to the winding-forming machine.
  • the proposed transfer process reverses the direction in which the sliver is drawn off, thus achieving the desired hook position of the fibers in the sliver.
  • a more detailed description of the tick position is given in the following exemplary embodiments.
  • the transfer could also be done by simply tilting the jug around 180 °, whereby the jug can be tipped into an empty jug below.
  • the desired hook position of the fibers in the sliver can also be taken into account directly when removing the fibers from the card by appropriately designing the doffing device.
  • Productivity is particularly high if the first drafting stage consists of six and the second of three drafting systems connected in parallel to one another. Each drafting system, based on the corresponding drafting stage, is given the same proportion of material for processing.
  • the construction height of the machine can be limited by dividing it into several adjacent groups within one drafting stage and, after the second drafting stage, enables the fiber webs formed in this way to be doubled with simultaneous cross-pulling.
  • the adjacent groups are driven together from one side within a drafting stage.
  • Fig. 1 shows schematically a system according to the classic method for winding formation already described.
  • the sliver 2 formed on one of several cards 1 is deposited in a can 3, which serves as an intermediate store.
  • the cans 3 are transported via a transport system or manually to an infeed table 4 of a wadding machine 5.
  • the wadding machine 5 generally has two parallel infeed tables 4, on each of which 3 fiber slivers are drawn from twelve cans and fed to a drafting system.
  • Each of these drafting systems which are not shown in detail, processes twelve supplied fiber slivers, for example a fiber sliver can have a mass of 5 ktex. That means a drafting system processes a total mass of 60 ktex, which corresponds to 60 g / m.
  • This mass is stretched in the respective drafting system with a 1.5-fold draft, so that the nonwoven fabric released from the respective drafting system still has a mass of 40 ktex.
  • These two non-woven fabrics of 40 ktex each are placed on one another or doubled and then wound up in the winding device 6 to form a cotton roll 7, called a roll for short.
  • the winding 7 now consists of a cotton web with a cotton weight of 80 g / m.
  • the coils 7 formed in this way are transported to a sweeping section 8, with six coils being presented for the rolling process of the sweeping section.
  • the wadding web unrolled from the individual windings 7 is guided over a drafting system, not shown, which executes a 6-fold delay.
  • the nonwovens delivered from the individual drafting systems are discharged via appropriate sweeping devices onto a conveyor table, on which they are placed one on top of the other or doubled.
  • the individual nonwoven fabrics have a mass of about 13 g / m when they exit the drafting system.
  • a cotton web of 80 g / m is again produced, which is conveyed to a winding device 9 to form a winding 10.
  • the winding 10 is ejected and submitted to a subsequent comber 11 for further processing by means of suitable transport devices.
  • the combing machine 11 has eight such coils 10 at the same time for further processing. As already described at the beginning, due to the doubling of the nonwovens at the sweeping section 8, a cross-sectional structure is achieved in the wadding web, the original band structure having been almost completely eliminated.
  • Fig. 2 shows a schematic representation of a system with the known tape duplication process.
  • the sliver 2 delivered by the cards 1 is temporarily stored in cans 3, which are presented in an infeed table 12 to a subsequent section 13.
  • the route 13 is presented, for example, with eight such cans 3, from which the fiber slivers are transferred via the infeed table 12 to a drafting system (not shown in more detail).
  • the slivers fed to the drafting system are stretched (e.g. 8-fold) and the fleece emerging from the drafting system is combined to form a sliver.
  • This sliver is placed in a can 14 via appropriate devices.
  • the cans are transferred to the infeed table 15 of the belt duplicating machine 16 by means of suitable transport devices or manually.
  • two infeed tables 15 are arranged on this machine, for example one Inlet table twelve cans are presented.
  • the fiber slivers drawn off from the cans 14 per infeed table 15 pass through suitable guides to a drafting system which subjects the fiber slivers to an approximately 1.5-fold warp. If one assumes that a fiber sliver has a mass of 5 ktex (5 g / m), a fiber fleece of 40 g / m each is obtained at the outlet of the two drafting devices assigned to the infeed table and not shown.
  • These two fleeces are relined and fed to a winding device 17 to form a roll 18.
  • the coils 18 formed in the process are presented to a subsequent combing machine 11 for further processing.
  • Both process lines are designed in terms of the number of individual process stages so that the fibers released by the card are present on the comber 11 with head hooks. These head hooks can then be loosened by the combing process.
  • FIG. 3 shows a schematic side view of a process line for forming cotton rolls by the method proposed according to the invention.
  • the correct hook position of the fibers with head hooks in the combing process is dispensed with in this example.
  • the technological disadvantages that may arise are accepted in special cases and partially offset by the increase in productivity by shortening the overall process in relation to the net proceeds.
  • the sliver 2 formed by the cards 1 is also deposited in cans 3. These cans 3 are transferred to an infeed table 19 of a winding machine 35.
  • the slivers, which are withdrawn from the cans 3, reach a first via a suitable feed device 20 Drafting stage S1, which is shown in the exemplary embodiments according to FIGS. 7 to 9.
  • the feed device 20 is shown schematically in a top view in FIG. 13.
  • the feed device shown here consists of two conveyor belts 21, 22, which are each intended to receive and convey three groups (I-111) of fiber belts (FIG. 12).
  • a group consists of 16 adjacent fiber slivers.
  • 48 cans must be placed in the infeed table 19 for each conveyor belt 21, 22.
  • a total of 96 cans are thus presented to the infeed table 19 for further processing. This number is due to the corresponding design of the first drafting stage S1 and a subsequent drafting stage S2.
  • the drafting stages S1 and S2 are arranged in parallel next to one another in three groups I to III in accordance with the feed of the fiber slivers 2.
  • the drive guide for all three groups I to III is carried out continuously.
  • FIG. 11 The schematic side view of the exemplary embodiment according to FIG. 12 can be seen in FIG. 11.
  • the sliver groups (I - III) fed by the conveyor belts 21 and 22 are fed in the first drafting stage S1 to two drafting units 23 and 24 arranged in parallel. It can be seen from FIG. 12 that three such drafting units 23 and 24 are connected to one another in terms of drive.
  • each drafting unit 23 or 24 is made up of 16 bands of 5 submitted ktex (5 g / m). This corresponds to a total mass of 80 g / m each. This mass is twisted twice on each drafting system 23, 24, so that the fleece emitted from the respective drafting systems 23 and 24 has a mass of 40 g / m.
  • These nonwovens 25 and 26 are combined or doubled and fed to a second drafting stage S2.
  • the second drafting system stage consists of three adjacent drafting systems 27, which stretch the supplied and doubled fleece three times, so that a fiber fleece 28 with a mass of approx. 27 g / m is delivered to the respective drafting system 27.
  • these nonwovens 28 are discharged laterally via sweeping devices (not shown in more detail) and placed on top of one another or doubled.
  • the cotton web 29 thus created in turn has a mass of 80 g / m, which is required for the subsequent combing process.
  • the cotton web 29 is guided over several calender rolls 30 and reaches the area of the winding rolls 31, over which a roll 33 is formed with the aid of a sleeve 32.
  • This winding 33 is ejected from the winding area by means of a schematically shown ejection device 34 and transported to a subsequent combing machine 11 for further processing by means of a transport system (not shown in more detail).
  • the entire band doubling which gives a measure of the uniformity of the wadding per unit length, is composed of a 24-fold doubling on the wadding machine 5 and a 6-fold doubling on the sweeping section 8. This results in a total duplication of 144.
  • the cross-sectional duplication which represents a measure of the uniformity of the wadding cross section and is achieved by the fleece doubling, is carried out six times in the example according to FIG. 1.
  • the tape duplication is composed of an 8-fold duplication on the section 13 and a 24-fold duplication on the tape duplicating machine 16. This results in a total duplication of 192.
  • the cross-sectional duplication is carried out on the belt duplicating machine, but only twice.
  • the total duplication according to the exemplary embodiment according to FIG. 3 corresponds to the number of cans presented, that is to say 96 in this case.
  • a double cross-sectional duplication is produced between the first drafting stage and the second. Subsequent to the second drafting stage, a triple cross-doubling is obtained, i.e. the total cross-sectional doubling is six-fold.
  • This cross-sectional duplication according to the example according to FIG. 3 corresponds to the cross-sectional duplication according to the known method according to FIG. 1. That means that with this arrangement an equally homogeneous cross-sectional distribution is obtained, by means of which the clamping effect already described in the combing pliers is advantageously influenced.
  • the total band duplication in this exemplary embodiment is lower than in the known methods according to FIGS. 1 and 2.
  • the amount of material processed at the same time is very high and ensures high productivity.
  • the design of the winding-forming machine 35 proposed according to the invention not only enables the processing of a large amount of material, but also ensures that the process is shortened. This means that in the exemplary embodiment according to FIG. 3, the process line including the combing machine and the card consists of a total of three processing stages, while four working stages are necessary in the known systems according to FIGS. 1 and 2.
  • FIGS. 4 to 8 different designs are proposed in FIGS. 4 to 8.
  • a decanting station 36 is connected between the card 1 and the winding-forming machine 35, the slivers deposited in the cans 3 being decanted into cans 37.
  • the decanting can be carried out by a decanting device (not shown in more detail), the sliver 2 being pulled out of the can 3 and placed in the can 37.
  • it could also be done by simply tilting the jug 3 by 180 °, the jug stick falling into the jug 37 positioned underneath.
  • the hooks of the fibers are reversed in relation to the feed direction of the sliver at the infeed table 19. That is, fiber slivers are also on the infeed table 19 Drag hooks are pulled off, so that 11 head hooks are present when the reel 33 is rolled up on the combing machine.
  • FIG. 5 Another possibility is shown in accordance with FIG. 5, the can 3 being filled from the bottom and the withdrawal at the inlet table 19 from the head of the can 3. This means that the conveying direction of the sliver 2, in which it was deposited on the card, remains in place at the infeed table 19.
  • An example is e.g. can be seen from DE-OS 16 85 629.
  • a tilting station 38 is provided between the card 1 and the winding-forming machine 35, in which the cans 3 are tilted in such a way that their bottom then points upward.
  • the can tilted in this way is presented to the infeed table 19 for pulling off the slivers from the bottom side.
  • the jug must be designed accordingly and, if necessary, certain positions must be provided for the beginning of the sliver.
  • FIG. 7 Another alternative for maintaining the correct tick position is shown in FIG. 7, in which the nonwoven fabric from the drum 59 of the card 1 is removed by a take-off roller 60 such that the fibers with head hooks are deposited in the can 3, as shown schematically.
  • head combs are again presented to the combing machine for combing out.
  • FIG. 8 shows a further possibility of correcting the tick position, a wrapping device 61 being provided following the wrapping-forming machine 35.
  • the roll 33 placed on support rolls 63 is unwound and wound onto a sleeve 66, which rests on support rolls 64.
  • the winding 65 thus formed arrives with the correct check mark position on the combing machine 11 and is processed there.
  • FIG. 9 shows a further embodiment of the device according to the invention, the first drafting unit stage being provided with four drafting units 39 operating in parallel.
  • Each of the drafting systems 39 is, for example, loaded with 16 fiber ribbons of 5 ktex each and has a delay of approximately 2.6 times.
  • a feed device 20 with four conveyor belts or other conveying means is necessary in order to transfer the fiber belts from the infeed table to the respective drafting device 39.
  • 64 cans are placed on the infeed table.
  • the nonwovens 42 emerging and discharged from the drafting devices 39 are laid one on top of the other and fed to a subsequent drawing device 40 of the second drafting device stage.
  • the wadding web formed by the doubling is warped in the drafting device 40 with a 1.5-fold warping, so that a wadding web of 80 g / m is then again present.
  • This wadding web passes over calender rolls 30 to the winding rolls 31, via which, as already described, a roll 33 is formed.
  • FIG. 10 shows a further embodiment, six drafting devices 41 being arranged in parallel in the first drafting stage S1.
  • Each drafting device 41 is fed sixteen slivers of 5 ktex each via a feed device 20, not shown.
  • the drafting devices 41 make a double twist on the sliver mass supplied, as a result of which a non-woven fabric 42 of 40 g / m is released in each case.

  • the total duplication in this embodiment corresponds to the can template and is 96 times.
  • the cross-doubling in this case is six times, while the cross-doubling in the previously described embodiment according to FIG. 9 is four.
  • the proposed division into two drafting stages with at least one cross-section duplication between these drafting stages achieves a homogeneous wadding in cross-section and enables a process shortening and thus an increase in productivity without reducing the quality of the wadding web presented to the combing process.
  • FIG. 14 shows a further variant of an embodiment with only one drafting stage S3.
  • the slivers 2 formed on the card 1 are presented directly to a feed table 19 via suitable transport devices or with the interposition of various devices according to FIGS. 4 to 7 in order to achieve the correct tick position, which feeds the slivers 2 in groups 45 to the respective drafting system 46.

  • This embodiment also enables a shortening of the process, since the card slivers are presented directly to the winding-forming machine 35 without interposing an additional stretch.
  • the arrangement of four drafting units 46 working in parallel enables the simultaneous processing of a large number of fiber slivers.
  • the webs released by the drafting units 46 have a mass of 20 g / m (ktex) after a 4-fold warping.
  • the mass of these nonwovens 47 formed after the drafting units 46 is relatively high with two drafting stages in comparison with the nonwovens of only 13 g / m in the known sweeping section in the classic process. This means that the nonwovens with a larger mass can be guided and deflected more easily since there is no risk of breakage. Safe fleece transport within the winding-forming machine 35 is therefore also obtained.
  • doubling device is not to be interpreted restrictively to a corresponding device, but rather also includes means that only allow at least two nonwovens to be brought together.
