JP5074149B2 - Apparatus for sorting or selecting fiber sliver made of textile fibers, in particular combing and having a feeding device - Google Patents

Description

  The present invention relates to a device for classifying or selecting a fiber sliver made of textile fibers, and in particular combing. Such an apparatus includes a supply device that supplies a predetermined number of fiber slivers discharged from different feeder locations to a pair of feed rollers of at least one drafting system unit that ejects fiber wrap, and And a combing device disposed downstream of the stretching system unit.

  In cotton combing, the card sliver is drafted and wound on a roll in the form of a lap. Combing is used to separate the short fibers from the wrap and increase the parallelism of all the fibers. As a result, since the average fiber length is relatively long, the breaking strength is increased, and the uniformity of the raw yarn that is subsequently produced is increased. In addition, squeezing is performed on the short fiber tuft separated from the wrap so that the squeezing is performed discontinuously. After the above pouring, the fiber tuft pieces are recombined. In cotton spinning, a flat combing machine is used.

  In a known device (EP 0 349 852 B1), the fiber sliver coming from the feed shaft is fed to three drafting systems, and the drafted fiber slivers are then placed one on top of the other (duplexed) And formed into a winding wrap at the collection device. In order to supply the winding wrap pretreated by the combing pretreatment machine to the combing machine, the plurality of winding wraps from the combing pretreatment machine is a winding wrap collecting container that receives the plurality of winding wraps. It is loaded on the transporting mobile body equipped with. The received winding wrap is positioned on the collecting container and is transported to the combing machine by the movable transporting movable body. Next, at an appropriate position for filling the plurality of heads of the combing machine, the winding wrap is released from the collection container by the transport moving body, and the non-loading core tube for the winding wrap is transported by the transport moving body. It is removed from the combing machine and collected in a suitable container on the transport moving body. After the return stroke of the transport mobile body, each core tube is discharged by the transport mobile body at an appropriate receiving station or at the combing pre-processor. The disadvantage of such a device is the burden required for the equipment for making the winding wrap and the transport of the winding wrap. A further problem is that when the winding wrap is rolled, a matting process is performed that prevents parallel alignment in the fiber wrap. A particular disadvantage is that the feeding action of the fiber wrap to the combing machine is made discontinuous by interruptions caused by the formation and conveyance of the wound wrap.

  EP 1 586 682 A discloses a combing machine in which, for example, eight combing heads operate simultaneously one after the other. These combing heads are driven by side driving means arranged adjacent to each combing head. Such lateral drive means have a gear unit that is drivably connected to the individual elements of each combing head by means of a longitudinal shaft. The fiber sliver formed by the individual combing heads is transferred to the subsequent drafting system one after another on the conveyor table, where the fiber sliver is drafted and then combined. Forms a common combing machine sliver. The fiber sliver created in the drafting system is then fed into the can through a funnel wheel (winder plate). A plurality of combing heads of the combing machine each includes a feeding device, a pivotally mounted fixed position nipper assembly, and a comb comb that scrapes and processes the fiber tuft supplied by the nipper assembly. A circular comb having segments and rotatably mounted, a top comb, and a fixed position removal device for removing the wiped fiber tuft from the nipper assembly. The disadvantages of such combing machines are in particular that a large number of devices are required and the production rate per hour is low. Although there are 8 individual combing heads, they total a total of 8 feeding devices, 8 fixed position nipper assemblies, 8 circular combs with comb segments, 8 tops Comb and 8 removal devices. A particular problem is the discontinuous manner of operation of each combing head. A further disadvantage is that large operating speeds are impossible, resulting from large mass acceleration and reversal movement. Finally, the amount of vibration of the machine is so great that the combed sliver loading becomes irregular. Furthermore, the distance between the nipper lip of the lower nipper plate and the clamping point of the removal cylinder is structurally and spatially limited.

  The problem underlying the present invention is therefore an apparatus of the kind described at the outset, which eliminates the disadvantages mentioned and is simple in particular with respect to the equipment and is produced in an amount that is produced per hour (production The present invention is to provide a device capable of significantly increasing the property.

This problem is solved by the features of the characterizing portion of claim 1.
That is, according to the first invention, an apparatus for classifying or selecting at least one fiber sliver made of woven fibers, and in particular combing, the apparatus comprising a predetermined number of discharges from different feeder locations. A feeding device for feeding a fiber sliver to a pair of feeding rollers of at least one drafting system unit that ejects a fiber wrap; and a combing device arranged downstream of the drafting system unit In the apparatus, the combing device is a rotor combing machine (2; 2 ₁ to 2 ₇ ) and the fiber wrap (16; 16 _{1 to} 16 ₇ ) is directly and uninterrupted with the rotor combing machines (2; 2 1 _{to 2 7)} is arranged to be fed into, times in order to rapidly rotate without being interrupted An apparatus is provided, characterized in that at least one roller (12, 13), which can be mounted, is arranged downstream of the supply means (8; 10, 11, 27a, 27b, 28a, 28b). .

  In contrast to the known devices, the number of required equipment can be considerably reduced by feeding the fiber wrap directly to the rotor combing machine, and in particular the continuous processing of the fiber material. Is possible. This advantage differs from known combing machines in that the rotor combing machine also reduces the number of equipment required and achieves a substantially increased productivity overall. Is emphasized by the fact that it allows continuous processing.

The aligned fiber tufts protruding outward from the wrap 16 are clamped by the clamping nipper 18 (reversing nipper) of the first rotor 12 (swivel rotor). The clamping device 18 of the first rotor 12 is premised on an extraction function.

Extraction:
As a result of the rotation of the swivel rotor 12 in which the reversing nipper 18 is arranged, the sandwiched fiber tuft is extracted from the fed wrap, but the fibers in the wrap 16 that are not sandwiched by the reversing nipper 8 are retained. A holding force acting on the wrap 16 is required. The holding force is applied by the conveyor element of the feeding means or by additional means such as a feeding tray or top comb. The element that generates the holding force assumes the function of the top comb.

Nipping 2:
The fiber tufts are aligned and transferred to the clamping device 21 (combing nipper) of the second rotor 13 (combing rotor). The distance is determined by the distance between the holding line of the inverted nipper and the holding line of the combing nipper when the combing device 21 is closed.

Combing:
The fiber tuft protruding outward from the combing nipper 21 includes fibers that are not sandwiched and are excluded by combing.

Piecing:
Fiber tuft 30 ₃ which has been treated up combing is placed on the take-out roller 14. The fiber tuft is placed on the take-out roller 14 and stretched and stretched by the surface of the take-out roller 14 which is acted by suction and is air permeable. Each fiber tuft is placed on top of one another, overlap as roof tiles, to form a web 30 _fourth fiber sections.

Web removal and formation of comba sliver:
The web 17 is removed from the take-out roller 14 at a position on the take-out roller 14 that is not affected by suction, and is guided into the funnel 34.

Comb sliver treatment:
The resulting comber sliver is doubled and drafted (drafting system 50) and then introduced into the can 3b, for example by the winder 3a.

FIG. 14 shows an arrangement comprising _seven combing pretreatment devices 1 ₁ to ₁₇ , in each case four rows of fiber sliver cans 5 a, 5 b have supply axles 4 ₁ to 4 ₇ (FIG. ₁₄ ). 1). Each supply creel ₄ for 1-4 ₇ downstream drafting system device comprising two drafting systems _6a 1 _{~6a 7} and _6b 1 _{~6b 7} are arranged, the two drafting systems _6a 1 _~6a downstream of the drafting system device comprising a ₇ and _6b 1 _{~6b 7,} rotor combing machine ₂ 1 to 2 ₇ wrapped _{161-164 7} is directly and continuously fed are placed . Downstream of the rotor combing machine ₂ 1 to 2 _7, sliver-on devices ₃ 1 to 3 ₇ is arranged.

  In FIG. 8, reference numeral 63 denotes a rotational cleaning roller. The rotational cleaning roller unravels components such as fibers, nep and dust from the combing element 31. Propel them to the collection / extraction device 56. In FIG. 9, each combing roller is similarly provided with a cleaning roller 65 with an extraction device 66.

  With the rotor combing machine 2 according to the invention, over 2000 nips / minute are achieved, for example 3000-5000 nips / minute.

  According to FIG. 15, the rollers 12 and 13 with the clamping devices 19, 20 and 22, 23, which are rotatably mounted, are additionally provided with suction channels 52 and 56 (suction openings), respectively. In the discharge area between the supply device 8 and the roller 12 and in the discharge area between the rollers 12 and 13, the suction channels 52, 56 affect the alignment and movement of the fibers being conveyed. In that way, the time for taking the fiber material from the feeding device 8 onto the first roller 12 and discharging it onto the second roller 13 is considerably reduced, thereby increasing the nip speed. . Suction openings 52, 56 are disposed in rollers 12 and 13, respectively, and rotate with the rollers. Associated with each clamping device 19, 20 and 22, 23 (nipper device) is at least one suction opening. Each of the suction openings 52 and 56 is disposed between a gripping element (upper nipper) and an opposing element (lower nipper). Inside the rotors 12 and 13, there are underpressure regions 53 to 55 and 57 to 59 generated by the suction flow in the suction openings 52 and 56, respectively. Underpressure can be generated by connecting to a flow generator. The suction flow at the individual suction openings 52, 56 can be switched between the underpressure region and the suction opening so that the suction flow is applied only at specific selective angular positions on the roller circumference. For the purpose of switching, valves or valve tubes 54, 58 with openings 57 and 59, respectively, in the corresponding angular positions can be used. Release of the suction flow can also be achieved by movement of the gripping element (upper nipper). Furthermore, the region of underpressure can be arranged only at the corresponding angular position.

  Furthermore, in the area of the supply device 8 and / or in the area of transfer between the rollers, an air flow can be provided. A supply source of the blast flow (the blast nozzle 39) is arranged inside the feed roller 10, and the supply source is in the direction of the first roller through the air permeable surface of the supply device or the opening of the air passage. Has an outward effect. Furthermore, in the region of the supply device 8, the elements that generate the air flow to be delivered can be fixedly arranged directly below or directly above the supply device 8. In the region of transfer between the rollers 12, 13, the delivery air flow source can be located at the periphery of the first roller 12 directly below or directly above each nipper device. A compressed air nozzle or air blade may be used to generate the delivery air.

  The suction flow B preferably affects not only the guidance but also the separation process between the wrap and the tuft to be extracted in the region of the supply device 8 and can shorten such a process.

  As a result of the arrangement of the additional air guiding element 60 and the side sieves 61, 62, the direction of the flow is influenced and the air engulfed by rotation by each rotor can be separated. In this way, the time for setting can be further shortened. In particular, the sieving elements between the first rotor 12 and the feeding device 8 on the lap and the sieving elements on each side of the roller have proven effective.

Fiber sections 30 ₃ which has been treated up combing passes into piecing roller 14 above the second roller 13.

  In the use of the rotor combing machine according to the invention, mechanical combing of the fiber material to be combed is achieved, i.e. mechanical means are used for combing. There is no pneumatic combing of the fiber material to be combed, i.e. no air flow is used, e.g. aspirated and / or delivered air flow.

  In the above-described rotor combing machine according to the present invention, there is a roller that has a clamping device that rotates rapidly without interruption. A roller that rotates with interruption, a roller that rotates stepwise, or a roller that rotates alternately between a stationary state and a rotating state is not used.
