Definitions

  • the present invention relates to methods for controlling a spinning machine, in particular ring spinning machine, with a drafting system, a spindle for receiving a yarn package and a ring frame and / or a spindle bank, wherein the drafting system, the spindle, the ring frame and / or the spindle bank through associated drives through a machine control is kept in operation in a coordinated manner and with a holding device for the yarn.
  • a spinning machine of this type is from the European patent publication EP 0 462 467 A1 known.
  • the retaining device is a clamping device attached to the spindle below the coping, which makes it possible to work with a comparatively short yarn length for the underwinding.
  • a ring spinning machine with a retaining device for the yarn be it an underwinding or clamping device
  • the individual operating parameters of the spinning machine must be precisely matched to one another. It may be necessary to specifically influence the yarn properties during spinning to ensure trouble-free operation.
  • yarn breaks should be avoided during spinning, Kopsroarvorganges and during piecing.
  • the yarn for the Kops ACvorgang should be able to be torn or cut, optionally with the use of appropriate aids such as cutters, tear-off edges on the retaining device, etc. This is especially true for solid yarns.
  • the tensile strength must be changed by changing the yarn twist and yarn fineness targeted.
  • the spinning process which is very important in itself, is still left to the spinning personnel today, who have to make the appropriate adjustments themselves for an optimal spinning process.
  • the operator needs extensive knowledge as well as a lot of experience, since different settings for the spinning process have to be made for different spinning programs. So it makes z.
  • the spin program provides a fine yarn, a coarse yarn, a normal yarn or even a fancy yarn.
  • the operator must also have knowledge of the current machine settings, in particular if he drives with a spinning program, which is in the border region of what the spinning machine is configured. This is to prevent the spin parameters for the spin-off process from being changed so that they are in an unacceptable range for which the machine was not originally configured.
  • the object of the present invention is therefore to propose a method which overcomes the above-mentioned deficiencies and is suitable for high operational safety and productivity, i. As few thread breaks as possible, even during the Abspinnvorganges distinguished.
  • the abrading process is initiated either by the creation of the top or the rear turn at the end of the winding of a yarn package, in particular a cop, especially at the time when the ring rail is shut down from its uppermost winding point on the yarn package to the bottom thread below the yarn package.
  • Optimum yarn strength is particularly important for the backwinding and underwinding process during the spinning process, as well as for the yarn-tearing or yarn-cutting process and for doffing during the bobbin change, as well as for the subsequent piecing process.
  • the spinning programs are expediently already stored in the machine control. However, the spinning program or programs can also be read into the machine control immediately before the spinning processes.
  • the user determines the desired spin program via an input unit.
  • the machine control selects from a plurality of Abspinnprogramms stored in the machine control function of the selected spinning program and the machine configuration and possibly other criteria via a selection or selection routine, which is also preferably stored in the machine control, the appropriate Abspinnprogramm and leads to this automatically given out.
  • the machine control may also suggest to the operator the optimal take-off program. He can confirm or reject the proposal. The machine control then initiates the selected Abspinnprogramm automatically at the given time. Furthermore, the machine control may also be configured so that an operator must initiate the spinning process manually or call the spinning program manually, e.g. by acknowledging a request by the spinning machine.
  • the spinning program can also be read via an input device in advance electronically from a (mobile) disk and stored in the machine control.
  • the spin program may include a variety of parameters. So z. B. the yarn count (Ne), that is, the fineness of the yarn, the yarn type, z. As smooth yarn, fancy yarn, such as flame yarn, knobbed yarn, etc., the yarn twist ( ⁇ ), the raw materials used, such as. B. cotton, chemical fibers, inorganic fibers, mixed fibers, etc. Furthermore, the sleeve lengths and diameters used as well as the desired Kopsgrösse or its diameter can be defined as a spinning parameters.
  • the machine configuration includes z. As ring diameter, rotor weight, drafting geometry or the drafting ratio, which sets the upper and lower limits of the rolling speeds.
  • z. B. ensures that the drafting rollers are operated exclusively in the speed ranges specified by the inserted gear ratio, and the speeds of the drafting rollers are not shifted by the change in delivery or the total delay during spinning in an unacceptable speed range.
  • the driving programs for the drafting or the drafting drive (s), the or the spindle drive (s) and the ring frame drive are calculated by the machine control using a computer unit and optionally in a memory, eg. B. in the machine control or in the drives or the converters stored.
  • Abspinnprogramm which sets the basis for calculating the driving programs of the drafting device drive or the drafting unit drives, the spindle drive or the spindle drives and the ring frame drive for the Abspinnvorgang at the end of the Garn stressesbewicklung by the machine control.
  • these travel programs determine the yarn count produced, yarn type and yarn twist during the spin-off phase.
  • the Abspinnprogramm calculates the data of the driving program so that due to compliance with the textile limits as little thread breakage in the last phase of Garn emotionstician or during spinning, during doffing or bobbin change and the renewed piecing a new yarn package arise. Furthermore, the Abspinnprogramm also ensures that the yarn properties are changed so that the yarn optimally clamps or underwinds and can be cut or cut when changing bobbins.
  • a yarn number in the range of Ne 10 - 100 are driven.
  • This yarn number range can now be divided into subranges of Ne 10-30, Ne 30-70 and Ne 70-100.
  • For each of these yarn number ranges is now one or more spin-off programs are deposited, which are tuned to these yarn count areas. If, in addition, spinning parameters such as raw material, yarn twist, yarn type and machine modification are taken into account, a single suitable spinning program remains at the end, which is determined by the machine control on the basis of the said selection criteria by the selection routine.
  • the selection routine may be a software program in which a corresponding algorithm for selecting the most suitable Abspinnprogrammes based on the aforementioned parameters is implemented.
  • a Abspinnprogramm which is intended for the number range Ne 10 - 30, so for a rather coarse yarn, is characterized, inter alia, by increasing the yarn count by increasing the total delay to allow the tearing of the strong yarn.
  • a Abspinnprogramm which is intended for the number range Ne 70-100, so for a rather fine yarn, has in the Abspinnphase a reduction of the yarn count by reducing the Automatverzuges in the Abspinnphase on to prevent too fast tearing of the fine yarn.
  • the Abspinnprogramm therefore provides for a change in the yarn properties in the Abspinnphase.
  • This change is preferably aimed at by changing the yarn count and / or by changing the yarn twist.
  • the change of the yarn number is z. B. achieved by changing the total delay.
  • a change in yarn twist can be achieved by changing the yarn delivery.
  • the yarn delivery is controlled analogously to the delay by the speed of the drafting rollers.
  • the rotation of the yarn or the rotation coefficient ( ⁇ ) of a certain time by the Abspinnprogramm be changed so that as possible favorable conditions in the area of the clamping device and the lower wind crown for the insertion, the clamping or the tearing or cutting of the yarn when removing the yarn packages result.
  • the yarn should not have too strong a rotation so that it is optimally able to be ripped or cut.
  • the yarn should also not have an all-too-weak rotation, so that the yarn does not crack undesirably during spinning and during re-spinning after the bobbin change.
  • the corresponding control values in accordance with the spin-off program are preferably transmitted to the drives or the associated converters of the drafting system, the spindles and the ring rail, etc., so that a yarn having the desired spinning properties is produced at the latest at the time of the backwinding or during the backwinding , This is done by appropriate parameterization of the inverters of the named drives.
  • the drives necessary for the Abspinnlui control values are recorded, which, for. B. in the case of the drafting system, according to the speeds of the drafting rollers and thus affect the delivery and the total delay.
  • the Abspinnprogramm is therefore preferably started before or at the beginning of the creation of the backwinding at the end of the winding of a yarn package by the machine control.
  • the spin-off program can also be called after the beginning of the backwinding.
  • the retaining device may comprise an underwinding and / or clamping device.
  • the underwinding device the yarn is wound around a, in particular rough, surface and held without clamping.
  • the clamping device the yarn is clamped, wherein the yarn can also be present in the clamping device as underwinding, in particular as a partial turn.
  • the retaining device for the yarn is preferably, i. especially in ring spinning machines, arranged in a position below the yarn package on the spindle.
  • the ring rail is driven from its uppermost Bewicklungstician creating the back turn down to the height of the retaining device.
  • the delivery speed in the drafting and the spindle speed can be coordinated so reduced that the desired yarn twist and yarn number is initially maintained and the yarn path on the yarn package as steep as possible.
  • the Abspinnprogramm can change the delivery or the draft of the drafting during the creation of the backwinding such that a yarn with a changed yarn count arises, so that less disturbances before, during and after the underwinding in particular when removing the bobbins with the associated tearing of the yarn, as well as when restarting the spinning process after doffing.
  • the ring frame remains during one to several revolutions of the spindle in the lowest position in the retaining device.
  • a clamping device of the ring frame preferably remains only until the yarn is placed and clamped over half to three quarters of the circumferential length in the winding area.
  • the ring frame is raised again to a position above the retaining device, whereupon then first the drafting system or the drafting device drive and then the spindle drive or both come to a standstill at the same time.
  • the drafting system can be kept in operation for a short period of time after the underwinding has been completed in order to supply a yarn length.
