Definitions

  • the invention relates to a method for laying a spinning cable according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 6.
  • melt spinning of single or multiple fiber bundles these are stored in the form of a tow for caching in a jug in order to perform the tow for further processing.
  • a relative movement is carried out between the spinning cable feed and the can, in order thus to obtain a uniform filling of the can.
  • the can is moved by means of a traversing device relative to the inlet position of the tow.
  • Such methods and devices as known for example from EP 0 875 477 A2, have the disadvantage that the pot to be filled must be moved, which in particular at the end of the filling requires a considerable effort and accordingly designed large drives.
  • the jug stands still during filling.
  • the tow is moved by the inlet in the pot by additional means in the form of a turntable.
  • This variant is known from EP 1 013 592 A1.
  • the tow is rotated by means of a rotatably driven turntable.
  • the turntable is held eccentrically in a rotatable bearing plate, the turntable movement will overlay.
  • the turntable is preceded by a conveyor which continuously guides the tow to the turntable.
  • On the turntable a guide tube is held in which the tow is guided.
  • the known method and the known device has the significant disadvantage that a twist in the tow is produced by the rotational movement of the turntable and the bearing plate when depositing the tow, which adversely affects the later withdrawal from the pot especially with thick tows.
  • the promotion of the tow is obstructed by additional deflections in the pot by additional guide means, so that only small filling densities can be achieved within the pot when depositing the tow.
  • No. 2,986,781 discloses a device for aldering a fiber strand into a container, wherein two oppositely arranged endless bander are used as conveying means.
  • the invention has the particular advantage that the tow is conveyed and stored directly without additional guidance means in the pot.
  • the movement of the tow is carried out for discharging into the pot by oscillating movements of the conveying means during conveying.
  • the conveying direction changes constantly, so that the inlet position of the tow into the pot is determined by the conveying direction.
  • the energy introduced into the tow by the conveying means can be used without any reduction to produce a filling density.
  • the oscillating Movements does not change the runnability of the tow.
  • the tow is directed to drop directly through the conveyor, so that unwanted interference effects are avoided in the tow.
  • the tow is placed completely swirl-free in the pot.
  • the tow is performed in a first advantageous embodiment of the invention by two superimposed oscillating movements of the conveyor.
  • the directions of movement of the two movements are aligned transversely to each other, so that each area in the pot can be filled evenly.
  • the movements can in principle be performed by an oscillating pivoting of the conveying means and or by an oscillating linear movement of the conveying means.
  • the conveying means can be advantageously carried out by two superimposed pivoting movements or by two superimposed linear movements or by a pivoting movement and a superimposed linear movement.
  • the movements of the conveyor are carried out at the same time preferably at different speeds.
  • a movement of the conveyer corresponding to a traverse is quickly performed, so that the tow is laid back and forth in a longitudinal direction to fill the can.
  • the second movement is performed slowly to create one position of the tow over the other within the can.
  • the speeds of movement of the conveyor is independently changed and adjusted according to a particularly advantageous method variant.
  • a device in which the carrier carrying the conveyor has assigned at least one drive, so that the conveyor is guided continuously in oscillating movements transversely to the conveying direction during conveying.
  • the conveying direction is constantly changed during the feeding of the tow, so that the tow takes a constantly changing inlet position in the pot.
  • a particularly simple and effective way to store the tow over the entire cross section of a pot evenly can be achieved by the advantageous development of the device according to the invention, in which the conveying means are associated with two movable support.
  • the movable carrier are driven by two independently controllable drive to each an oscillating movement, wherein the directions of movement of the carrier are aligned transversely to each other.
  • a rocker which carries the funding.
  • the rocker is associated with a drive, for example, to perform a quick pivoting movement for depositing the tow.
  • the superimposed second movement of the conveyor can be achieved in that the mounting of the rocker is mounted on a second rocker or held on a carriage.
  • the second rocker or the carriage can be performed by an associated drive a slow movement to guide the first rocker and thus superimposed to guide the conveyor.
  • a holder which holds at least the conveying means and a carrier and which can be guided between several depositing positions. This allows the conveyor after filling quickly lead to another storage position with an empty pot.
  • the funding is preferably formed by two driven reel rollers.
  • the drive of the reel rollers is carried out regardless of the introduced by the carrier position changes of the reel rollers.
  • the method according to the invention as well as the device according to the invention are particularly suitable for laying down thick tows with large spun tiers of the fiber bundles of, for example,> 12,000 dtex, which is used in particular for further processing for staple fibers.
