Definitions
- the invention relates to a method, or to an apparatus for executing the method for sorting fibers of a fiber structure via the feed center! a fiber sorting device is supplied.
- a device was therefore proposed in the published PCT application WO 98/04765 for carrying out the separation of short fibers, dirt and other constituents by means of an air flow, the air flow being generated essentially in the transport direction of a nonwoven fabric.
- the nonwoven fabric passed through an air duct is subjected to a holding force at two points, so that it is ensured that the long fibers to be obtained are not removed by the air flow.
- the object of the invention is now to propose a method or a device by means of which an increased degree of separation and an increased separation quality compared to the known pneumatic methods can be achieved.
- this object is achieved by a method in which the fiber structure is clamped transversely to its direction of transport and the free end projecting beyond the clamping point is exposed to an air flow which is able to remove non-clamped components (e.g. short fibers, nits, dust, etc.). detach from the free end and lead away.
- non-clamped components e.g. short fibers, nits, dust, etc.
- the selection process is carried out with air in a manner similar to the mechanical separation process on the combing machine at an open end of a fiber structure (cotton wool, nonwoven fabric, fiber band, etc.).
- the air flow generated in the direction of the free end of the fiber structure makes it possible to blow out and remove the non-clamped components.
- the intensity of the air flow depends on the size of the fiber mass.
- the fiber structure be divided into individual fiber packs with individual fibers which are essentially elongated and approximately parallel to one another before reaching the sorting device. This makes it possible to exert a targeted clamping action with respect to the now elongated fibers, which ensures that only a few long fibers are entrained in the sorting process.
- fiber packets be formed discontinuously from the free end of the fiber assembly by means of a corresponding withdrawal element.
- Such processing of the fibers into thin fiber bundles or bundles of fibers is already known from the principle of the fibroliner. With this principle, the fiber bundles are ordered ends, with the short fibers in the front end (clamping line) of the fiber bundles. With a fiber mass prepared in this way, it is possible to carry out a targeted clamping action in the subsequent selection process (sorting process) in order to separate the short fibers located in the head end.
- the fiber package is clamped during the sorting process at a predetermined distance from its front end, which is exposed to the air flow.
- This front distance to the head end of the fiber package is comparable to the ecartement of the combing machine. All the short fibers located in the head area, which are not held by the clamping point, are removed when an air flow is applied.
- the air flow - viewed from the clamping point - be directed in the direction of the free end of the fiber structure or the fiber package.
- the air flow can be generated by a vacuum and / or a pressure source.
- the banding can take place by stacking the sorted fiber packages. This process corresponds to the soldering process in the conventional comber.
- a method is proposed in which at least two fiber groups are fed to the fiber sorting device simultaneously and the ends of the fiber groups are exposed to a common air flow. It is advantageous if the ends of the individual fiber assemblies are brought together and air is blown between the ends of the fiber assemblies, starting from the area of their clamping points. This makes it possible to blow compressed air in a targeted manner into the merged ends in order to capture and separate all short fibers located inside the ends and not clamped.
- At least one additional compressed air flow is generated after the respective clamping point in the direction of the free end and on the outer surfaces of the merged ends of the fiber assemblies. It would be conceivable to apply the air pulses generated in this way at different time intervals.
- the invention is also achieved by a device, wherein clamping devices are provided which clamp the fiber structure at a distance from its free end and means are provided which produce an air flow from the clamping point to the free end of the fiber structure.
- clamping devices are provided which clamp the fiber structure at a distance from its free end and means are provided which produce an air flow from the clamping point to the free end of the fiber structure.
- means are provided to gradually dissolve the fiber structure supplied by the feed means into individual fiber packages with individual fibers that are essentially elongated and aligned parallel to one another and with means for transferring the fiber packages to a subsequent sorting device. It is important that the structure of the fiber bundles formed, or the longitudinal alignment of the fibers, is retained during the transfer to the actual sorting device.
- the feed means be formed from a drafting system and that the means for producing individual fiber packs consist of a rotatably mounted roller which forms a clamping point with a rotatably mounted sieve drum, which is opposite the delivery point of the drafting system.
- the drafting arrangement can preferably be an apron drafting arrangement.
- the take-off roller be wrapped around a part of its circumference, at least in the area of the nip, with a belt which is mounted all round.
- the belt rests on the circumference of the sieve drum over a section of the sieve drum after the clamping point. This ensures optimal guidance of the fiber package formed. This means that the fiber bundle is positively guided, which means that the individual fibers keep their position during removal.
- the sieve drum be provided with elevations distributed over its circumference at a distance. Together with the belt that is wrapped around the take-off roller, these elevations form a secure chere clamping point and ensure a safe entrainment of the fibers held in the clamping point.
- the elevations can be made of elastic material in order to produce a gentle clamping. It is also possible to provide the extraction roller which interacts with the screen drum with an elastic coating.
- a further embodiment is possible, the elevations on the sieve drum being omitted and instead being attached to the rotating belt. It only has to be ensured that a targeted clamping force can be applied in the take-off area between the screening drum and the take-off roller in order to pull the fiber packs out of the end of the fiber assembly presented. In addition, the safe further transport of the fiber packets must be ensured without the occurrence of compression.
- the distance between the elevations attached to the sieve drum or on the belt must be greater than the length of the longest fiber in the fiber structure.
- a rotatably mounted separating drum is assigned to the axis parallel to the sieve drum, which is provided with a plurality of suction slots directed radially outwards, the suction slots corresponding to a vacuum space in the position of the smallest distance from the outer periphery of the sieve drum, which is inside the separating drum fixed and connected to a suction.
- the distance between the outer jacket of the screening drum and the separating drum can be selected so that a clamping effect is exerted on the fiber package at the time of the application of a negative pressure in the appropriately positioned suction slot.
- the clamping line generated is at a distance from the front end of the fiber bundle, which means that all jammed components (eg short fibers) are removed from the generated air flow in the suction slot.
- means are provided at least in a partial area between the area where the belt rests on the outer circumference of the screening drum and the transfer area to the separating drum in order to generate a vacuum inside the screening drum.
- the vacuum only has to be large enough so that the position and orientation of the individual fibers in the fiber package do not change during transport to the transfer point.
- short components such as dust, for example, can be extracted from the fiber mass already in this area by the application of the negative pressure.
- a rotatably mounted take-off roller is provided which is parallel to the axis of the separation drum and which affects the outer circumference of the separation drum.
- the take-off roller can be provided with a clothing on its outer circumference.
- an overpressure source in the interior of the screening drum, by means of which a compressed air flow is generated in the direction of the suction slot.
- a further embodiment of the invention results if at least two fiber assemblies are fed to the fiber sorting device by means of conveying means and movably mounted clamping elements are provided for each fiber assembly, which cooperate with a common guide element.
- At least one air nozzle is arranged in the guide means, the opening of which - viewed in the conveying direction of the fiber associations - opens into the connection and between the clamping points and is connected to a compressed air source.
- the air nozzle extends over the entire width of the supplied fiber dressings.
- a variant is also possible, in which several fiber bundles (e.g. fiber ribbons) lying next to one another are fed to the clamping point.
- fiber bundles e.g. fiber ribbons
- fiber dressing can include, for example, a nonwoven fabric, a wadding, a fiber band or the like.
- the advantageous developments listed below can also relate to an embodiment, with only a single ner fiber structure is fed to the clamping elements. (That is, without bringing the ends of at least two fiber assemblies together).
- the guide element be provided with opposite guide troughs, in each of which a conveyor roller dips, which serves as a conveying means.
- air nozzles in the area and following the clamping surfaces of the clamping elements are integrated in the clamping elements and are connected to a compressed air source. This makes it possible to apply compressed air to the end projecting beyond the clamping point in the longitudinal direction. This intensifies the separation effect.
- a pair of rollers forming a clamping line be arranged downstream of the clamping elements.
- the feed devices prefferably be displaceable in the direction of the pair of rollers when the clamping elements are released, so that the front end of the fiber structure can be grasped by the clamping line of the subsequent pair of rollers.
- This pull-off process is equivalent to the pull-off process of the combed fiber beard in the combing machine.
- At least one of the rollers of the pair of rollers be provided as a hollow cylinder with openings directed outwards, the cavity being connected to a vacuum medium.
- the outward openings are only on a portion of the circumference of the hollow cylinder available, so that during the tear-off process, on the one hand, there is a closed clamping line in the pair of rollers and, on the other hand, suction of the drawn-off good fibers is prevented.
- An additional fixed diaphragm can be provided in the interior of the hollow cylinder, which causes the outward opening to close.
- a belt forming unit is preferably arranged downstream of the pair of rollers, it being possible for this to be formed from a screen drum and a draw-off roller which interacts with the screen drum.
- the interior of the screen drum is connected to a vacuum source and covers are provided on the inside of the screen drum that cover the interior except for a partial section in front of the nip between the screen drum and the Isolate the extraction roller from the ambient air.
- the belt forming unit can also be formed from a rotating conveyor belt which is arranged transversely to the direction of discharge of the pair of rollers. It is advantageous to provide the conveyor belt with air-permeable openings and to provide means for at least below the delivery area on the conveyor belt Generation of a negative pressure. This ensures safe removal of the fiber packets onto the conveyor belt.
- a device wherein at least one guide means extending along the free end of the fiber bandage is provided and the fiber sorting device is supplied with the fiber bandage via a conveying means which interacts with a guide element.
- a movably mounted clamping element advantageously interacts with the guide element and forms a clamping point with the latter. It is further proposed that at least one air nozzle is provided in the guide element, the opening of which opens after the clamping point between the free end of the fiber structure and the guide means and is connected to a compressed air source.
- the guide element which can preferably be a plate.
- the air flowing along the plate creates a negative pressure area which causes the free end to be drawn towards the surface of the plate and thus ensures that air flows through the free end.
- the same effect has already been used in another form of application, namely for detaching a cotton end from a cotton roll, which e.g. was described in EP-A1 482 475.
- the air flow is only used to detach the cotton web and not for selection, especially since there is no defined clamping line and the detachment process takes place at intervals of at least three hours.
- the proposal to make the end of the guide means or the plate flexible makes it possible to move the free end of the plate into a different position for the blowing process or the transfer process of the blown end, which supports the processes described above, or relieved.

- the separating drum 30 is designed such that the slot 36 is sealed off from the surroundings of the separating drum 30 when no air slot 38 is opposite the opening 36.
- the separating drum 30 is held in position via schematically shown guide rollers 40, at least one of the guide channels 40 being connected to a drive 42. Seen in the direction of rotation of the separating drum 30, elastic clamping elements are fastened on the outer casing AU behind each of the air slots 38. The mode of operation of these elastic clamping elements 44 is discussed in more detail below.

- the clamping effect between the belt 6 and the clamping element 18 on the detached fiber package 24 is maintained during the passage between the rollers 5 and 8, thereby ensuring that the fiber package 24 is targeted without changing its structure (slow-pitched fibers)
- the fiber package As soon as the fiber package has passed the roller 8, it is held on the surface SU of the screen drum 3 by the negative pressure in the channel 20.
- the front end K of the fiber package 24 is still on the terminal strip 18 while the fiber package 24 shown is in the direction of the separating drum 30 is transported, further fiber bundles 24 (not shown) are pulled out of the end E by the subsequent clamping strips 18.
- the sliver 10 is demanded continuously, while the removal process for producing the fiber bundles 24 takes place discontinuously
- the fiber package 24 shown reaches the delivery area A between the screening drum 3 and the subsequent separating roller 30 during further transport or with a further rotation of the screening drum 3. Due to the simultaneous rotation of the separating roller 30, a gill element 44 hits the fiber package 24, thereby causing a clamping between the outer jacket SU of the screening drum 3 and the clamping bar 44 arises.
- the angular position during operation of the screening drum 3 and the separating drum 30 is chosen such that the clamping bar generated by the clamping bar 44 never occurs at a distance from the front end K of the fiber package 24. This distance from the head end of the fiber package can be equated to the ecartement in the combing machine and can be adjusted by changing the angular position between the two drums 3 and 30.
- the end of the suction slot 38 overlaps the opening 36, as a result of which an air flow takes place inwards as a result of the negative pressure in the tube 32.
- the front end, or the head K of the fiber package 24, which projects beyond the clamping point of the clamping element 44, is drawn into the suction slot 38.
- All the components (short fibers) of the end protruding into the suction slot 38 that are not clamped by the clamping element 44 are now released from the fiber package 24 by the air flow and discharged inward into the channel 32.

This makes it possible to retain and also remove short components that have not yet been completely eliminated by the air flow and also soiling during the removal process. This means that the comb element 105 serves as an additional separation aid.
- FIG. 5 shows a further possibility of a belt forming unit 95, where instead of a sieve drum a rotating conveyor belt 110 is used, which is provided with air-permeable openings 111. This can be seen in particular from FIG. 6.

- the air jet starting from the air slot 63, penetrates the end E1 in the region where the two ends of the slivers F1 and F2 overlap.
- the guide part 58 including the rollers 54, 55 and 60, 61, can be displaced in the direction of the roller pair 85, so that the tip of the blown out End E1 comes into the nip between the rollers 82 and 83 It is also possible, instead of moving the guide part 58 onto the pair of rollers 85, to move the pair of rollers 85 towards the guide part 58 in order to grasp the fibers of the free end E1
