Definitions

  • the present invention relates to a method for controlling the fiber mixture and a system for controlling the fiber mixture for dispensing predetermined amounts of fiber flakes.
  • fiber blends made up of different fibrous components i.e. fibers of different origins, types, qualities, colors or other characteristics, are usually blended to produce fiber blends, which are then carded and fed into further spinning processes.
  • the fiber mixture can be carried out, for example, by filling the various types of fiber into the respective filling shafts and depositing them on a conveyor belt that runs underneath the shafts using the feed rollers. This creates a continuous layer structure on the conveyor, which is then fed to a roller, whereby this roller separates individual flakes from the layer structure and ensures a good mixture of the various fibers in the various layers. By controlling the rotation speed of the individual feed rollers, it is possible to determine the desired proportions of the individual fiber components.
  • the object is achieved in whole or in part by the features of the invention.
  • a method is proposed for controlling the fiber mixture of a fiber preparation machine that combines fibers from different raw materials, length, thickness or color into yarn, such as flock mixture or fiber sliver mixture.
  • the method comprises:
  • the method can control the fiber mixture of a fiber preparation machine in order to maintain or improve the quality of the flake mixture or the sliver mixture.
  • the analysis of the sensor data is an analysis of the color or the multispectral properties of the composition of the fiber mixture.
  • the method can analyze the composition of the fiber mixture.
  • the adjustment of the fiber preparation machine comprises an adjustment of the speed.
  • adjusting the fiber preparation machine includes adjusting the fiber mass over time.
  • the composition of the fiber mixture can be kept constant or improved.
  • the object is achieved in whole or in part by the features of the invention.
  • a system is proposed for controlling the fiber mixture of a fiber preparation machine that combines fibers from different raw materials, length, thickness or color into yarn, such as flock mixture or sliver mixture.
  • the system comprises:
  • a sensor configured to detect the fiber mixture
  • An evaluation unit connected to the sensor; the evaluation unit is configured to collect all sensor data and parameters of the fiber preparation machine and to adjust the fiber preparation machine.
  • the system can control the fiber mixture of a fiber preparation machine in order to maintain or improve the quality of the flake mixture or the fiber sliver mixture
  • the senor is a camera.
  • Figures 1 and 2 show a schematic representation of a fiber preparation plant with a system 100 and method according to the invention.
  • Figures 1 and 2 show a schematic representation of a fiber preparation plant with a system 100 and method according to the invention.
  • the same reference numerals are used for features that are identical and/or at least comparable in their design and/or mode of operation, even if they are shown in different exemplary embodiments. Unless these are explained in detail again, their design and/or mode of operation corresponds to the design and mode of operation of the features already described above.
  • the system 100 of Fig. 1 comprises a mixing machine 150, a sensor 110 and an evaluation unit 120 which is connected to the sensor 110.
  • the mixing machine 150 which can be a precision mixing system such as UNIblend or a weighing box system, comprises a rotating conveyor belt 151 and three similarly designed dosing devices 152 which are arranged in a row above the conveyor belt 151. It is understood that the embodiment shown in Fig. 1 is not limited to three dosing devices 152, but any number of layers 197 can be arranged above the conveyor belt 151.
  • Each dosing device 152 consists, as explained in more detail below, of a filling shaft and two to three feed rollers 153 arranged at the lower end of the shaft, as well as an opening roller 154.
  • the flakes 191 present in the shaft are captured by the feed rollers 153 rotating in the respective directions and fed to the opening roller 154 through the conveyor gap formed between these two rollers. The latter rotates faster than the feed rollers 153 and releases flakes 191 from the fed flake wadding 192 and feeds them through a channel in the form of opened, loose flakes 191 onto the conveyor belt 151.
  • the loose flake bundles from the two further dosing devices 152 are placed in layers 197 on the first layer formed by the flake bundle and guided by the conveyor belt 151 to the end of the mixing machine 150.
  • the three layers 197 are thus compressed and then caught in the conveyor gap of two feed rollers 153.
  • the feed rollers 153 feed the layer structure 199 thus formed to an opening roller which separates flakes 191 from the layer structure 199 and transfers them via a shaft for subsequent processing, as shown in Figure 2.
  • the senor 110 or the camera 110, is arranged on the shaft and records the fiber mixture of the mixing machine 150.
  • the images are sent to the evaluation unit 120.
  • the sensor can also be placed on the shaft of the subsequent machine or the belt deposit. The analysis precision can be increased even further by combining several consecutive sensors.
  • the evaluation unit 120 collects all sensor data, or all images and parameters of the fiber preparation machine, or the mixing machine 150, and then analyzes the sensor data or the images to determine the composition of the fiber mixture of the layered structure 199.
  • the fiber mixture is usually made up of different fiber-like components, i.e. fibers of different types, qualities, colors or other characteristics, and is cut or mixed to produce fiber mixtures that are then carded and fed to the further spinning processes. These fibers can have different shapes and colors, and the evaluation unit 120 checks or analyzes the color of the composition of the fiber mixture of the layered structure 199.
  • a comparison of the determined composition with a predetermined composition of the fiber mixture takes place in the evaluation unit 120. This comparison can be carried out several times and the speed of the fiber preparation machine can be adjusted based on the result. In particular, the evaluation unit can adjust the speed of the feed rollers 153 so that the composition matches the predetermined composition or with the predetermined waste or with the predetermined fiber mixture.
  • the setting can be made, for example, in such a way that the fiber types from one filling shaft are deposited on the conveyor belt 151 faster than those from the other filling shafts.
  • the rollers of the filling shafts must be slowed down so that a continuous layer structure 199 is created on the conveyor element, which is then checked by the sensor 110.
  • the opening roller 154 can rotate faster or slower in order to separate many or few flakes 191 from the flake wadding 192 and form a flake flow that corresponds to the predetermined composition.
  • the evaluation unit can measure the fiber mass over time.
  • the filling level of the fiber flakes 191 in the individual shafts remains approximately constant, it may be that for a filling level and predetermined speed of the feed rollers 153, the desired fiber quantities are cut unevenly on the rotating conveyor belt 151 due to the different bulk density. Therefore, with the present invention, it is possible to keep the quality of the flake mixture or the fiber band mixture constant or to improve it when measuring the fiber mass.

Abstract

La présente invention concerne un système (100) de commande du mélange de fibres d'une machine de préparation de fibres. La machine de préparation de fibres combine les fibres ayant des matières premières, une longueur, une épaisseur ou une couleur différentes pour former un fil, tel qu'un mélange de flocage ou un mélange de brins. Le système (100) comprend un capteur (110) qui est conçu pour détecter le mélange de fibres, et une unité d'évaluation (120) qui est reliée au capteur (110). L'unité d'évaluation (120) est configurée de telle sorte qu'elle collecte toutes les images et tous les paramètres de la machine de préparation de fibres et pour régler la machine de préparation de fibres.
