Definitions

  • the present invention relates to a method of producing staple fibers from melt spun filaments, as well as an apparatus for carrying out the method.
  • the staple fibers are produced in a two-step process.
  • a plurality of filaments are spun from a polymer melt in a first step, and combined to a tow after cooling.
  • the tow is deposited in a can.
  • a plurality of tows are withdrawn by a treatment unit from a plurality of cans that are accommodated in a can creel.
  • the tows are joined to form one combined tow, which is treated, and finally cut to staple fibers.
  • Such two-step processes are used in particular for processing very coarse total deniers, such as, for example, greater than 200,000 deniers.
  • the invention is related to such method and apparatus.
  • the tows be temporarily stored between the first process step and the second process step, since it is common practice to join in the treatment unit a plurality of tows produced in a first spinning process to a combined tow, and to further process the latter.
  • cans are provided that are reciprocated by costly transportation devices between the spin unit and a can creel associated with the treatment unit.
  • a can magazine is provided that temporarily stores previously filled cans.
  • a further object of the invention is to further develop the known method and the known apparatus such that they permit further processing the freshly spun tow to the end product with as little time of interruption as possible.
  • melt spun filaments are formed into a tow, which is successively deposited into each of a plurality of cans accommodated in a can creel. The tow is then withdrawn from the cans and treated and cut.
  • the invention distinguishes itself essentially in that it does not require costly auxiliary devices for transporting the cans to the spin units.
  • the invention provides for depositing the tow directly into a can that is accommodated in a can creel.
  • the interaction of the spin unit and the can creel permits designing in an advantageous manner a compact combined production line, in which the can creel represents a common interface between the spin unit and the treatment unit.
  • the further developments of the invention are especially advantageous, which provide next to a first can creel a second can creel with a plurality of cans.
  • an advantageous variant of the method makes it possible to deposit the tow in the first process step into the cans of the first creel, while at the same time, in the second process step, the tows are withdrawn from the cans of the second creel.
  • the spin unit includes in accordance with an advantageous further development of the invention, a movable depositing device that is supported and guided by guide means above the creel. With that, it is possible to deposit the tow in any desired position of the can creel into a can accommodated therein.
  • the tow may be deposited both by an oscillating movement that is imparted to the depositing device, or by an oscillating movement that is imparted to the can accommodated in the can creel. This ensures a high degree of filling with a corresponding filling density.
  • An especially advantageous further development of the apparatus according to the invention provides for associating the depositing device to a feed system, which advances the tow after withdrawing it from the spinnerets.
  • This further development is especially advantageous for being able to fill can creels with a large number of cans and the therewith connected great travel distances with the tow under an adequate tension.
  • the feed system associated to the depositing device is used for building up a tensile force.
  • a preferred further development of the invention provides for arranging the spinnerets and the withdrawal systems of the spin unit above the can creel. This arrangement permits mounting the spinnerets in a centered or offset relationship with the can creel. With the arrangement in tiers it becomes possible to keep the deflections small that are needed for depositing the tow.
  • the further development of the invention which provides for associating to each can in the can creel a withdrawal guide element that is adapted for moving between an idle position and an operating position, is especially advantageous for permitting on the one hand an uninterrupted removal of the tows from the cans, and on the other hand for making available a full opening cross section of the cans for filling.
  • FIG. 1 is a schematic top view of a layout of the apparatus according to the invention.
  • FIG. 2 is a side elevation view of the apparatus showing the apparatus in somewhat greater detail
  • FIG. 3 is a front elevation view of the can creels of the apparatus.

  • the spin unit 1 includes a plurality of spinning positions for melt spinning a plurality of filaments, which are joined to a tow 11 by means of a withdrawal system 9 . Via the withdrawal system 9 , the tow advances to a depositing device 10 that is arranged for being positioned above the can creels 2 . 1 and 2 . 2 .
  • the can creels 2 . 1 and 2 . 2 each accommodate a plurality of cans 13 .
  • the depositing device 10 is associated with the can creel 2 . 1 , and in the process of filling a first can 13 of the creel.
  • the depositing device 10 can be moved to each can of the can creel 2 . 1 for successively filling the cans 13 of the creel 2 . 1 with the tow.
  • the cans 13 accommodated in can creel 2 . 2 are already filled.
  • the tows of the cans 13 of can creel 2 . 2 are jointly withdrawn by the treatment unit 3 and combined to one tow 14 .
  • a plurality of guide rolls 22 are associated with the can creels 2 . 1 and 2 . 2 on their respective delivery sides.
  • the treatment unit 3 comprises a withdrawal system and draw system as well as additional treatment devices for cutting the tow 14 to the desired staple fibers.
  • the cans 13 of the can creel 2 . 1 are being filled with a tow, whereas the cans 13 of the can creel 2 . 2 are being emptied, in that the treatment unit 3 withdraws the tows.
  • the association will be changed.
  • the tow 14 that is withdrawn and treated by the treatment unit 3 is then formed by the tows that are withdrawn from the cans 13 of the can creel 2 . 1 .
  • the cans 13 of the can creel 2 . 2 are filled with the tow 11 .
  • the special advantage of the method according to the invention and the apparatus of the invention lies in particular in a substantially continuous operation of the two process steps with only short times of interruption.
  • the avoidance of costly transportation steps brings considerable savings in time.
  • the can creels 2 . 1 and 2 . 2 can be arranged relative to each other, without having to take into account any transportation paths or transportation steps. It is thus possible to provide very compact arrangements of can creels, which directly cooperate with the adjacent or superposed spin unit 1 or with the adjacent or superposed treatment unit 3 .
