Definitions

  • the invention relates to a device on a card for filling a round can with sliver, z. As cotton, man-made fibers o. The like.,
  • the sliver off a rotatable storage head and can be stored in rings in the round pot being arranged during the filling of the storage head above the round can and the round pot fixed on a rotatable can plate to a vertical Axis rotates, and in the after filling a full can and before filling a blank pot, the local assignment between the storage head on the one hand and the full and empty cans on the other hand changes (can change), and a full can be conveyed and an empty can be fed (KannenaPM).
  • Rotary can changers (US 4208768) and linear can changers (EP 967169 B) are known for changing round cans on a card. These can changers are basically designed to hold at least three possible can positions:
  • the round cans are moved and change positions.
  • the filing speed must be reduced as a rule, since otherwise fiber material is conveyed between the round cans.
  • it is desirable to change the round cans quickly so that the production of the card does not have to be significantly reduced.
  • fluctuations in the weight of the band occur during large changes in the delivery speed, which can adversely affect the technological result up to the end product.
  • a quick change of the round cans is associated with various difficulties.
  • the round cans have no consistently stable structure and can therefore be damaged by high forces.
  • the round cans differ from customer to customer, which makes the adaptation of recordings difficult.
  • the round cans have a high weight in the filled state, which causes high forces during short change times during acceleration.
  • the turntable (storage head) remains permanently stationary.
  • the round cans are moved below the turntable, the rotary can changer on a semicircular path and the Linearkannwechsler on a straight line.
  • the can changer provided in a reserve position empty round can for filling with sliver in a filling position below the turntable and after filling a sliver filled with sliver can be brought into a discharge position from the filling position below the turntable.
  • the invention is therefore an object of the invention to provide a device of the type described above, which avoids the aforementioned disadvantages, especially when changing the can, ie when changing the local assignment between the storage head on the one hand and a full can and a empty can on the other hand, a movement of the round cans avoids a temporal shortening of the can change and allows in a simple way equalization of the filing density of the sliver in the round can.
  • the possible can positions of three positions are reduced to two positions .
  • the round cans under the storage head but it is the storage head moved over the round cans.
  • the full cans can be moved in the known devices due to their high weight only with high forces and not in a short time.
  • the operator removes the full cans and replaces them with an empty can, so that only two can positions need to be reserved.
  • the space requirement of the device according to the invention is significantly lower than that of the known devices.
  • the position of the crossing points is varied, ie, the cross points are freely distributed.
  • the crossing points are as congruent as possible congruent in the vertical direction one above the other, ideally not at all. As a result, a homogenization of the filing density of the sliver in the round can is achieved.
  • Another particular advantage is that by a displacement device in a structurally simple way, the displacement of the storage head is realized both during the filling process to even out the sliver storage and the can change from a full can to a empty can.

However, the drive of the two can plates can be done with a motor, as this is harmless when replacing the full against an empty pot. Ie. both can plates rotate permanently. In this arrangement, the operator removes the full round can and replaces it with an empty one, which means that only two can positions need to be reserved.

Abstract

L'invention concerne un dispositif monté sur une cardeuse (K), servant à remplir une canette ronde (15) avec un ruban de fibres (14), par exemple en coton, en fibres synthétiques ou similaires, avec lequel le ruban de fibres (14) peut être délivré par une tête de dépose rotative (19) et déposé en anneaux dans la canette ronde (15). Lors d'un changement de canette, c'est-à-dire lors d'une modification de l'association spatiale entre la tête de dépose (19) d'une part et une canette pleine et une canette vide d'autre part, en vue d'éviter un mouvement des canettes rondes (15), de rendre possible une réduction de la durée du changement de canette et, de manière simple, une homogénéisation de la densité de dépose du ruban de fibres dans la canette ronde (15), la tête de dépose (19) peut être déplacée dans l'espace par rapport aux canettes rondes (15) en vue du changement de canette. Un dispositif de déplacement déplace la tête de dépose (19) durant l'opération de remplissage en vue d'homogénéiser la densité de dépose du ruban de fibres et, en vue du changement de canette, effectue le déplacement de la tête de dépose (19) d'une canette pleine remplie de ruban de fibres vers une canette vide.
