Definitions

  • the invention relates to an apparatus for laying a tow into a can, as well as a method for laying a tow into a can, of the general type disclosed in DE 102 32 745 A1.
  • a feed device advances a tow into a can.
  • a movement control system reciprocates the feed drive in an oscillating manner in a plurality of directions of movement.
  • the feed drive is mounted on a first pivotal support, which is adapted to be pivoted back and forth by a drive transversely to the direction of advance.
  • the pivot axis of the first support is formed on a second support, which performs a superposed, transversely directly pivotal movement, so that the feed device is adapted to be guided in two orthogonal axes.
  • the supports are arranged in a machine frame above the can, with the supports being adapted to be guided between two positions of deposit by means of a linear guideway.
  • the known apparatus and the known method have in particular the advantage that the can being filled can be kept stationary in a position of deposit, while the tow is being deposited.
  • the advance of the tow for being deposited into the can occurs exclusively by the movement of the feed device, so that the tow advances into the can in a controlled manner as a function of the respective position of the feed device.
  • the apparatus of the invention totally departs from the solutions so far known in the art.
  • the apparatus of the invention departs from the intent to arrange the tow feed device in a machine frame above the can.
  • the invention utilizes a multiaxial robot, with the feed device being held at the free end of a robot arm. With that, it is possible to perform the movements of the feed device for advancing and laying the tow into the can with a maximal degree of freedom.
  • the robot comprises at least three axes of movement, which permit realizing and controlling the movements of the feed device for laying the tow and filling the can. To fill the can, it is thus possible to perform three movements in superposed fashion to obtain a uniform deposit of the tow over the cross section of the can.
  • At least two cans are associated to the feed device, which can be alternately filled.
  • a further development of the apparatus according to the invention comprises a deflection roll for guiding the tow and which precedes the feed device.
  • This embodiment distinguishes itself in particular in that the tow may be supplied continuously and uniformly from an upstream treatment apparatus.
  • the feed device and the deflection roll are preferably mounted to a support plate that is rigidly connected to the end of the robot arm.
  • the apparatus is especially preferred, wherein the movement of the robot arm is controlled such that the support plate performs a pivotal movement about a pivot axis that is formed by the axle of the deflection roll. With that, the advance of the tow remains unaffected by the pivotal movement of the feed device.
  • a second pivotal movement is initiated preferably by the movement of the robot arm in such a manner that the support plate can be pivoted about a second pivot axis, which is formed as a tangent to the deflection roll at the level of the advancing tow. With that, no additional means are needed to prevent the tow from dropping from the deflection roll.
  • the advance of the tow to the deflection roll remains largely unaffected by the laying motion of the feed device.
  • the feed device by two driven feed rolls, which interact for advancing the tow.
  • other feed devices are possible, such as, for example, rolls with strippers or conveying belts.
  • As cans for receiving the tow one may use rectangular cans or also round cans.
  • the method of the invention wherein the direction of the movements of the feed device for laying the tow is freely selected and adjusted, distinguishes itself in particular in that the tow can be laid into cans of any shape with a uniform filling density. In particular, it permits generating laying patterns inside the can, which lead to an improved mass distribution of the tow inside the can. Also, it prevents pileups in reversal points when laying the tow.
  • the flexibility in forming laying patterns in the can can be improved by varying and adjusting the amplitudes of the movements of the feed device and/or the speed of the movement of the feed device to lay the tow as a function of the geometry of the can.
  • a maximal flexibility is reached, in that the movements of the feed device are varied and adjusted independently of one another in the direction of movement, the movement amplitude, and/or the speed.
  • the method of the invention wherein the sequence of movements of the feed device is predetermined by a control algorithm of a robot that guides the feed device with its arm, distinguishes itself in that it achieves not only a high flexibility in laying the tow, but also a very high reproducibility in filling the cans.
  • the uniformity of the filling degrees of the individual cans has an advantageous effect in particular in further processing, since normally a plurality of individual tows are simultaneously removed from a plurality of cans and joined to a combined tow. Because of the uniform filling, there is also a guarantee for a uniform removal of the tow.
  • the apparatus and the method of the invention are especially suited for continuously laying into cans, in a two-step staple fiber process, synthetic multifilament fiber bundles that are combined to a tow.
  • the apparatus of the invention is directly associated to a spin unit, by which one or more fiber bundles are spun from a polymer melt.
