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.

  • yarn breaks should be avoided during spinning, Kops Batvorganges and during piecing.
  • the yarn should be able to be torn or cut for the cop change operation, if appropriate with the use of appropriate aids such as cutters, tear-off edges on the retaining device, etc. This applies in particular to yarns with high strength or elongation.
  • the tensile strength or elongation can 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 with a high degree of automation, which overcomes the above-mentioned deficiencies and is characterized by a high level of operational reliability and productivity, i.

  • Yarn parameters such as yarn count, initial raw material of the fibers or the type of yarn can also be included in the pre-cut program.
  • the pre-run program can be combined with a unwinding and / or piecing program or executed as a separate program.
  • Choosing a cop switching process program may also mean that the machine controller assembles a cop switching process program from stored program modules. This can be z. B. done by the selection module.
  • the abrading process is initiated either by the creation of the top and / or backwind at the end of the winding of a yarn package, especially a cop, especially at the time when the ring rail is lowered from its topmost winding location on the yarn package to the bottom level 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 controller selects from a plurality of Kopsciclui programs stored in the machine control depending on the selected spinning program and the machine configuration and optionally other criteria via a selection or selection routine, which is also preferably stored in the machine control, the appropriate Kops grillpens program and does it automatically at the right time.
  • the machine controller may also suggest to the operator one or a selection of optimal cop switching process programs. He can confirm the proposal or make a selection or reject.

For example, he may also choose a different cop switching process program, or he may change certain parameters underlying the proposed program, such as yarn count or yarn twist, individually. So the operator z. B. enter the desired yarn count and / or yarn twist itself during spinning, if for certain reasons a deviation from the specification is desired.

Furthermore, the machine control be configured so that an operator manually initiate the Kops CARIS or call the Kops CARIS program manually, eg by acknowledging a request by the spinning machine.

B. in creating the backwinder play a role, whether the deducted from the spindles full cops are passed over a head collecting a collecting container, or whether the Cops are fed via a link device on so-called Pegtrays directly to a winder. If the spinning machine contains a head collecting device, then it is advisable to produce a larger number of back turns with a smaller angle of wrap, so that the back turns of the heads deposited in the collecting container are not detached by mutual friction. In the case of the link facility, however, the cops are guided individually to the winding station via transport plates. Here, a smaller number of back turns with a steeper Umwindewinkel sufficient because the cops are exposed to its surface no significant mechanical stress.
