Definitions

  • the invention relates to an apparatus and a method for filling rectangular cans with a sliver or roving.
  • the device comprises a turntable and a belt channel arranged in the turntable, and means for translational displacement of the can.
  • the jug facing the end of the band channel is eccentric to a rotation axis of the turntable.
  • the turntable is displaceable with a drive about the axis of rotation in a rotary motion.
  • a sliver or roving is produced, which is not further processed directly after production.
  • a sliver is stored in a variety of container forms.
  • a filing usually takes place automatically in cans. Accordingly, almost all exits of carding machines or stretching devices can be found in the form of a cyclo-shaped fiber sliver in a jug.
  • the cans used can be either round cans or rectangular cans.
  • the sliver produced by the card sliver or web is taken over by the depositing device with calender rolls.
  • the sliver is introduced into a band channel which is disposed in a can to be filled over a can.
  • the jug itself is set in a rotary motion in the case of a round can and in a translatory motion in the case of a rectangular jug. Due to the eccentric arrangement of the band channel in the turntable and the movement of the pot, the sliver is placed annularly in the pot. The movement of the pot causes the individual stored loops to be staggered.
  • DE 101 62 717 discloses a control of the rotational speed of the turntable as a function of the can movement. Through the disclosed measures it succeeds the
  • EP 0 457 099 discloses a method which allows a high production speed of the fiber belt forming machine for the filling of rectangular cans.
  • the jug is moved under the turntable in its longitudinal direction back and forth. This results in a tile-like storage of the loops formed by the rotational movement of the turntable.
  • the pot is in its respective reversal point to a sliver thickness additionally shifted laterally by tilting to the side of the pot.
  • the jug is tilted back to the previous position so that every second row is deposited at the same location. This method also leads to an unsatisfactory mass distribution over the cross section of the pot.
  • Another known device according to DE 102 05 061 attempts to counteract the disadvantages of using cans by dispensing with them.
  • the disclosed device deposits the sliver on a base, forming a so-called band package.
  • Such formed tape packages have the disadvantage that when moving the tape pack from one machine to the next, the sliver unprotected by the external influences, which can lead to the falling of the tape package.
  • the use of such tape packages therefore requires a high logistical effort.
  • the object is therefore to provide a device for filling cans, which is a mass distribution-optimized Can filling and thus a high uninterrupted tape mass in a pot allows.
  • the object is achieved by the features in the characterizing part of the independent claims.
  • To solve the problem it is proposed to provide a device in which the translational displacement of the pot during filling in two mutually perpendicular axes is feasible, wherein the axes are arranged perpendicular to the axis of rotation of the turntable.
  • the cans to be filled have an aspect ratio of 2 or smaller, preferably 1.5.

  • the rectangular cans used today are used in a narrow elongated shape and are only slightly larger in width than the diameter of the loops of the sliver, which are stored therein.
  • the cans to be filled according to the invention have a smaller aspect ratio.
  • the movements of the pot are characterized by strong accelerations in the reversal points or changes in direction, which is necessary to avoid unwanted material accumulation by slowing down the movement in one direction and subsequent acceleration in another direction.
  • the sliver supply is doing with a constant resp. operated or controlled independently of the movements of the jug.
  • the jug is held by a jaw carrier to master these movements. This is equipped with at least one drive and a fixation of the pot.

Abstract

L'invention concerne un dispositif pour remplir des pots (33) rectangulaires d'un ruban de fibres (3) ou d'une mèche. Ce dispositif comprend un plateau tournant (7, 31) situé au-dessus du pot (33) et un canal à ruban (6) disposé dans le plateau tournant (7, 31), ainsi que des moyens pour déplacer le pot (33) par translation, l'extrémité du canal à ruban (6) faisant face au pot (33) étant disposée de manière excentrée par rapport à un axe de rotation (8) du plateau tournant (7, 31). Un mouvement de rotation (9) autour de l'axe de rotation (8) peut être imprimé au plateau tournant (7, 31) au moyen d'un système d'entraînement. Selon l'invention, les pots (33) peuvent être remplis avec un rapport de longueur (A/B) inférieur ou égal à 3, de préférence inférieur ou égal à 2 et idéalement égal à 1,5 et le mouvement de translation du pot (33) pendant le remplissage peut être exécuté selon deux axes (42, 43) perpendiculaires, ces axes (42, 43) étant disposés perpendiculairement à l'axe de rotation (8) du plateau tournant (7, 31).
