Definitions

  • the present invention relates to fiber processing machines or systems with a plurality of different fiber processing stages.
  • a short-staple spinning mill comprises a plurality of fiber-processing stages between the bale store and the bobbin packing or bobbin conveying system.
  • the fibers are processed in the form of an elongated, coherent structure (ribbon, sliver, yarn), while in the "upstream” stages the fibers are processed in various, non-contiguous or relatively coarse Shapes are processed, e.g. free-flying, as a cotton ball, in bales etc.
  • production changes ie changes in the material flow per unit of time, of a fiber processing machine are brought about by changing the "processing width", that is to say by changing the width of the material flow (transverse to the direction of flow) through the processing elements of the machine, without reducing the flow rate per time and Change length unit of width significantly.
  • the "specific production” (the production per unit length of the effective machine width) can thus be kept essentially constant, which means an approximately constant quality.
  • the overall production of the machine (flow per unit of time across the entire width) can, however, be changed in a controllable manner.
  • the principle can be used to control or regulate a fiber processing plant.
  • a target value for the overall production of a processing stage can be determined and the processing range of this stage can be changed accordingly, either directly or as a function of a determined deviation in a target / actual comparison.
  • the invention is particularly advantageous where the machine works with a template in the form of a wadding and in particular in the control or regulation of a feed machine for a card sliver.
  • the invention also encompasses a fiber processing device with means for controlled change in the processing range of this device.
  • the device could, for example, comprise a working element of variable effective length, for example a working element consisting of a plurality of adjacent, individually drivable working elements, so that the number of elements in operation can be controlled.
  • This variant could be used for bale removal, as already indicated in our European patent application No. 221 306.
  • the length of the work organ can be kept constant while the width of the template can be changed.
  • the width of a filling shaft (parallel to the length of the feed roller) of a feed machine could be changed, for example as described in DOS 3149965 or DOS 3542816.
  • the invention is advantageous both in a continuous system and in a batch system, i.e. the individual stages can normally run with a continuously changeable production, or they can work in the so-called stop / go mode, the production remaining constant within a go interval.
  • the invention can advantageously be combined with other control methods, e.g. In our European patent No.93235 we describe a method for optimizing stop / go conditions in a bale removal machine. Fine production changes have to be accepted. Such fine production changes could e.g. be carried out with the help of the present invention, so that the specific production and thereby the quality remains constant.
  • a target value for the total production of a stage can represent either the current production or the average (effective) production of the stage.
  • the latter can only be used for a certain period of time (measurement) are determined, taking into account any production fluctuations (eg switch-off intervals during stop / go operation, changes in current production during "continuous" operation).
  • Fig. 1 shows four processing stages of the blow room / opening of a short batch spinning mill.
  • Level K represents the carding machine
  • level S the card feed
  • level M a mixing operation
  • level A the bale removal.
  • Other stages can also be provided, for example an additional cleaning stage between bale removal and mixing.
  • the entire system is controlled by a master computer uP, a control signal q representing the total production of the card is obtained and supplied to the master computer uP so that the latter can determine the corresponding production of each stage upstream of the cards via corresponding lines s, m, b. This controls the material flow MF1, MF2, MF3 between the different stages.
  • each upstream stage determines its production on the basis of two signals, namely one Signal from the host computer ⁇ P and a signal from the immediately downstream stage.
  • This arrangement is well known and can operate either continuously or discontinuously, as previously described.
  • a production change in an upstream stage is usually carried out by changing a roller speed, a conveying speed or a "processing depth” (e.g. the removal depth of a bale opener).
  • a processing depth e.g. the removal depth of a bale opener.
  • Fig. 2 shows schematically a material template V and a work roll W of a job.
  • the roller W normally has a predetermined length L, which is provided, for example, with a clothing or with noses or teeth in order to be able to process fibers over this length L.
  • the technology depends on the speed of the roller W, its clothing, the (predetermined) thickness t of the template V and the fiber density in the template.
  • a necessary change in production is usually effected by changing the roller speed.
  • the clothing type, template thickness and template density cannot be changed accordingly, this means a change in technology (i.e. quality) in the conventional process.
  • it is proposed that that a production change is carried out by changing the predetermined length L and / or the predetermined width B, all other parameters being able to be kept constant and in particular the flow rate per hour per unit length of work roll W being kept constant
  • Fig. 2 shows schematically by dashed lines two possibilities for changing the production in this way, namely a "spreading” or “narrowing" of the original width, e.g. between the values B and B1, and an extension or shortening of the working length L by assembling the roller W from adjacent, individually drivable roller parts W1 to W4.
  • the invention is not restricted to the use in connection with work organs in the form of rollers and also not to a template in the form of a cotton wool.
  • a cleaning station where the fibers are transported through the machine in the form of free-flying flakes, the effective working width of the machine could also be changed according to this invention.
