Definitions

  • the invention relates to a method for optimizing and keeping the fiber quality constant in the automated mixing of bales with textile fibers of different quality, according to the preamble of claim 1.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a method for optimizing and maintaining the fiber quality in the automated mixing of bales with textile fibers of different quality, which enables the current mixing result to be continuously checked and corrected for one or more predetermined target values.
  • the invention achieves the stated object with a method which has the features of claim 1 and a device for carrying out the method which has the features of claim 11.
  • the quality of the fibers of a bale is measured not only once, as in the methods according to the prior art, but each bale is measured layer by layer, as a result of which variations in quality within an individual bale are better taken into account.
  • the device for carrying out the method according to the invention shown schematically in FIG. 1, essentially consists of a bale removal device 2 with a fiber removal member 4 movably arranged along a transport path 3, a sampling device 6 attached to the removal member 4, which is arranged via a fiber pattern transport system 13, e.g. in the form of a mechanical conveyor belt or a pneumatic pipe transport system, is connected to an automatic measuring and control device 5.
  • the removal member 4 is connected to the mixer 7 via a fiber transport system 14.
  • the bales to be mixed with textile fibers of different quality 1 a , ... 1 k , ... 1 n are arranged on both sides along the transport path 3 of the fiber removal member 4 of the bale removal device 2.
  • the fiber ablation element 4 is shifted from the bale by the measuring and control device 5 in order to remove the quantities and qualities of different fibers required for a desired fiber quality from the individual bales 1 a , ... 1 k , ... 1 n and feed the mixer 7.
  • a fiber sample is taken from the processed bale 1 k by means of the sampling device 6 attached to the removal member 4 transported via the fiber pattern transport system 13 to the automatic measuring and control device 5 and analyzed there.
  • the fiber sample to be analyzed is preferably taken from the surface of the processed bale 1 k facing the removal member 4.
  • the fiber measuring lines (HVI) from Spinlab Inc. or Motion Control Inc. can be cited as examples of textile analysis devices typically used in measuring and control device 5.
  • these analysis devices must be completely automated, so that the sample preparation and the sample transport also take place fully automatically.
  • the adaptation of these devices known in textile analysis to a fully automated operation, as takes place in the method according to the invention, can be carried out by the average person skilled in the art with the usual knowledge and is therefore not described in more detail here.
  • the quality parameters of the individual bales 1 a , ... 1 k , ... 1 n can either be determined in a conventional manner before the mixing operation and fed into the memory 8 of the measuring and control device 5.
  • a sample can be taken from all the bales 1 a ,... 1 k ,... 1 n by means of the sampling device 6 and fed to the measuring and control device 5, and the data determined and analyzed be stored in memory 8.
  • the removal device 4 is now controlled in such a way that the measuring and control device 5 is based on the stored quality parameters of the individual bales 1 a ,... 1 k ,... 1 n , and the desired target value for the fiber mixture to be achieved
  • a removal program is calculated from suitable algorithms present in the memory 8 and can be executed by suitable control of the removal member 4 via the data line 9.
  • the removal device 4 is preferably controlled via a digital interface 12 (typically RS232, V24, RS485 or LAN), which specifies the location and the respective height of the individual bales 1 a ,... 1 k ,... 1 n Amount of the fiber material to be transferred.
  • a digital interface 12 typically RS232, V24, RS485 or LAN
  • the superiority of the method according to the invention is now based on the fact that the quality parameters of the individual bales 1 a ,... 1 k ,... 1 n entered in the memory 8 of the measuring and control device 5 can be continuously updated, so that quality differences in detail Bales can be fully captured and taken into account in the mixing algorithm.
  • the optimization of the individual fiber parameters takes place in such a way that the measuring and control device 5 calculates the theoretical fiber quality of the continuously achieved mixture on the basis of the continuously determined actual fiber qualities and fiber quantities, which have this quality, and with predetermined target values (maximum limits 10 and Minimum limit 11) is compared and, if necessary, corrected by changing the originally calculated removal program (see FIG. 2).
  • the continuously performed comparative measurements of the fiber parameters can be shown optically (see FIG. 2) and / or processed into acoustic signals, which then enable manual control of the bale removal device 2. However, it is also possible to use these comparison measurements for the automatic control of the bale removal device 2.
  • the measuring and control device 5 can also be used to monitor and control a plurality of bale removal devices 2 (two removal lines are shown by way of example in FIG. 2).
