Definitions

  • This invention relates to the interaction of linked process stages e.g. a ring spinning machine, if necessary with an automatic operator assigned to this ring spinning machine, and a winding machine linked to the ring spinning machine, which in turn is equipped with a yarn cleaner which is suitable for recording the yarn quality.
  • linked process stages e.g. a ring spinning machine, if necessary with an automatic operator assigned to this ring spinning machine, and a winding machine linked to the ring spinning machine, which in turn is equipped with a yarn cleaner which is suitable for recording the yarn quality.
  • Quality control is an increasingly important task for both short staple and chemical spinning (see e.g. EP 26472; EP 196090 as well as the article "On-line quality control for false twist texturing” in chemical fibers / textile industry from October 1991, page 1196).
  • the material flow tracking and in particular the head tracking for quality control or quality control is a topic that deserves increasing attention in the spinning mill.
  • the patent literature includes the following publications (among others) on this topic: CH 410718; DOS 3603002; DOS 3628045; EP 392249; DOS 4003428; DOS 4002500; DOS 4111488.
  • DOS 3712654 It has already been proposed in DOS 3712654 to collect data both in a spinning machine and in a winding machine and to operate the system on the basis of the linking of these data. In particular, a special cop preparation is provided for this purpose, which should also serve as a sorting point. How the system is to be operated is not clearly apparent from DOS 3712654, and in DOS 4103428, which was later submitted by the same applicant company, it is pointed out that the earlier proposal required a "relatively large technical effort" . This may be due to the fact that the data that would have to be collected on the ring spinning machine in accordance with DOS 3712654 are not normally required to operate the machine itself.
  • the "package” (cop, spool) is considered as a unit.
  • the data collected refer to the package in its entirety, even if the thread has been continuously monitored.
  • the invention relates to a plant or to a plant part which consists of linked process stages.
  • the process stages can be designed in such a way that the errors of the upstream stage (s) must be dealt with in a downstream stage in such a way that they are not forwarded.
  • the flow capacities of the stages can be coordinated with one another or dependent on one another, so that an increase in the error rate when delivering to the downstream stage exceeds a certain limit, the ability of this stage, the required flow rate to meet predetermined minimum quality requirements and to maintain when the supply is interrupted is impaired.
  • Each stage can include a large number of production sites.
  • the invention is particularly suitable for use in a fully automated or low-operator system, for example in a system that has no scheduled human activity for at least two days (Friday evening to Monday) and during the night shift Interventions can continue to work.
  • the control of such a system is much easier if a process control system is provided at least for the more complex system parts.
  • the upstream stage (s) can provide information depends on its sensor technology. This level will normally include at least a minimal sensor system (thread breaks). However, it will often not be equipped with the same sophisticated sensors (see e.g. EP 322470) as the subsequent stage, at least if the further processing in the subsequent stage is to prevent the error from being forwarded (error elimination; error correction).
  • the sensors of the upstream stage should preferably be supplemented such that any faults in the coil (or in the container) can be located. If the machines of the upstream stages are not provided with any suitable sensors, certain data can still be collected, for example, by means of automatic controls or data acquisition machines, and the location in the coil or in the container can be determined from the fill level of the container or from the structure of the coil getting closed.
  • thread breaks are of particular importance. As is clear from the article "Effects of thread breaks in ring and OE rotor spinning on the yarn properties and running behavior in weaving preparation and weaving" (S. Schlichter and Prof. J. Lunensch, Dornbirn, man-made fiber conference, September 1985) When expression comes, thread breaks are a sign of bad yarn. These are not just the break points themselves (which can be replaced by good splices), but rather weak or inferior places in the uninterrupted yarn, which later lead to processing difficulties.
  • the aim of this invention is to further develop the cooperation between the machines mentioned in a modern spinning mill.
  • the invention provides, in particular, a system which includes a spinning machine with an automatic control device assigned to this machine and a further processing machine linked to the spinning machine, and means for checking the quality of the yarn packs delivered to the further processing machine and for identifying those Spinning station which has produced a certain package, characterized in that the said agent is indirect, for example via the spinning machine control, or can issue a control command directly to the operating machines for decommissioning a specific spinning station and the operating machine is provided with means for executing this command.
  • each spinning station can be provided with a respective device for stopping the supply of material to this spinning station and the automatic control device with means for actuating this device.
  • a suitable device is shown in EP 3188938.
  • the automatic control device can be designed to carry out other measures to shut down a spinning station, e.g. for switching off a drive motor individually assigned to this spinning station.
  • This first aspect of the invention is of course particularly advantageous if the further processing machine is provided with means for checking a yarn in a manner which cannot be carried out in the spinning machine itself, e.g. for testing a ring spun yarn for the presence of thick / thin parts, number fluctuations, periodic unevenness, hairiness, etc.
  • the invention is concerned in particular with a system which comprises a spinning machine with an automatic control device assigned to this spinning machine and a further processing machine linked to the spinning machine, the automatic control device having means for collecting data relating to the states of the spinning stations of the Spinning machine is provided.
  • a system is described in DOS 3909746.
  • the system is characterized by the fact that the state data of the Allocate machine time and forward the data obtained therefrom to the further processing machine, so that a controller of the further processing machine adapts the treatment of each individual package delivered by the spinning machine to this further processing machine to the status data generated when this package was formed.
  • the machine time is determined by the packing cycle of the spinning machine.
  • This cycle includes e.g. for a ring spinning machine, a start-up phase, a phase of normal spinning, a final phase and a doff phase.
  • the exact process characteristics of each such phase can be adapted to the spinning conditions, but will in any case be detectable at least in the control of the spinning machine at any time (e.g. by reading from a memory).
  • the machine time can be determined indirectly via the time of day, whereby means must be available in order to assign a given time to an ascertainable package formation cycle. This can be done in that, at the end of a pack formation cycle, the status data corresponding to a specific pack are directly assigned to this pack or to a carrier for the pack.
  • the means for performing this step are known and are not discussed in this description. You can e.g. can be taken from DOS 3603002 or 3628045.
  • the respective status data can be assigned indirectly to the corresponding package using a suitable information management system.
  • a suitable system is described in German Patent Application No. P 40 24 307.9.
  • cop tracking The above-mentioned acquisition of the condition data of packs is referred to as cop tracking in the following.
  • the CH 410718 mentioned at the beginning contains statements about this Cop tracking.
  • the present invention also includes such a bobble tracking, which means that a functional combination with the steps described here and with bobble tracking belongs within the scope of the invention.
  • cop tracking either the sleeves of the cops or carriers for the sleeves, so-called peg trays, can be coded.
  • the cops can be taken over by the ring spinning machine in the order of the spindles and subsequently converted, for example, to special peg trays with integrated semiconductor memory (for example according to DOS 4024202), which only circulate in the winding machine, so that in this way the individual cops are assigned to the spindles or spinning positions of the ring spinning machine.
  • the origin of an individual spinning cop or an individual pack without marks can be inferred by replicating the distance covered by the latter on a computer, individual sensors having to be present at certain points along the path covered by the pack.
  • a suitable system has been shown in PCT Patent Application No. WO 92/02669.
  • the controls of the individual machine components must have the following stored data:
  • the operating machine generates a status image of the spinning positions it manages, the machine time being stored as a reference for the cop assembly. These data are continuously transferred from the operating machine to the spinning machine during operation.
  • the spinning machine provides a status image of all spinning positions of the machine, experience data being stored as in a logbook, for example the time as a reference for the build-up of the cops in the individual occurrences.
  • This data is sent to the Transfer winder.
  • the transmission can be controlled directly or via a process control computer before the cop transfer begins.
  • a process control computer serves as a data interface in the case of different networks in the spinning plant.
  • the winding machine maintains a list of all adopted
  • Preferred or adapted processing of packs which have been assigned to the predetermined categories of status data for example preferred processing of cops without thread breaks in the cop preparation of a winder and / or a predetermined preparation operation for cops with thread breaks or the diversion of such cops to a designated preparation point).
  • the operating machine can comprise at least one data memory, which at any time (during the operation of the machine) contains an "image" of the status of the spinning positions assigned to this machine, and is provided with a clock which is equipped with a clock Spinning machine control can be correlated.
  • the time of a detected state change can then be stored in a predetermined relationship to the state change itself, so that the time of the change, the new state and a spinning position identification are linked to composite data.
  • Means are also available for at least occasionally transferring status data to a corresponding data memory of the spinning machine.
  • the status data is assigned to the machine time at the latest after this transfer.

  • Each cycle is completed by a doff phase, the cops formed during this cycle being removed from the respective spindles by a suitable doff device (not shown) and replaced by new sleeves. During the doffing, each spindle stands still.
  • the machine After doffing, the machine is accelerated to its operating speed, the course of this (run-up) phase being able to be adapted in order to minimize the breakage of the starting thread or to form the base of the cop.
  • the machine runs after one predetermined spinning program (in the controller) to form a cop of a predetermined size.
  • the operating speed can be controlled in order to keep the number of thread breaks (eg per hour) at an (empirically determined) level or a yarn property that can only be checked on the winder (eg the hairiness) within limits.
  • the machine When the cop is almost full, the machine begins a final phase (spinning), where the machine slows down and is prepared for the subsequent doff phase. This cycle is repeated through the entire operating time of the machine and defines "the machine time”.
  • the "machine time” determines the bobbin forming process - for each machine time (in the cycle) there is a corresponding point in the bobbin forming characteristic, if you want to determine an event in the bobbin forming (eg a thread break) compared to the bobbin forming characteristic, this can be done by means of the machine time.

  • the processing capacity of the winding units must be selected in such a way that within a machine cycle of the ring spinning machine (ie while the spinning machine is producing a new bobbin lot), the bobbin winder has processed all the bobbins of the previous cycle (of the previous lot).
  • the adaptation of the rewinding capacity to the ring spinning capacity represents an important decision when planning the plant. For cost reasons, a large reserve of winding capacity will rarely be available.

  • the determination of the number of thread breaks is not a problem for either the winding machine or the ring spinning machine.
  • the spinning positions of the ring spinning machine are not provided with their own sensors (for example according to EP 436204; EP 432401 or DOS 4011944)
  • the machine can be provided with a suitable mobile data acquisition device, of which the previously mentioned operating machines are only to be understood as examples.
  • communication capability is often also guaranteed today, for example according to DOS 4008794 or PCT / CH 92/00014. However, this is also not essential, since it is also known to hold the data directly on the package itself, for example according to DOS 4112073 or DOS 4024202.
  • a ring spinning machine Before changing the bobbin, a ring spinning machine must be brought to a standstill (and then brought back up to the operating speed), i.e. the spool change represents an interruption in production. Accordingly, it should be kept as short as possible and this means that the spools cannot be treated individually.
  • Such information can be seen from DOS 3942304 or can be derived therefrom.
  • Such information can also be used "downstream" from a "separation point" e.g. in a machine assembly of a cross-wound spinning machine with a double-wire twisting machine, as has been shown in DOS 3802900.
  • the machine is indicated at 70 in FIG. 5. It includes winding units, of which only three locations 72, 74, 76 are indicated in FIG. 5; In a practical design, twenty or more winding units are normally found.
  • the cop preparation is indicated at 78.
  • Peg trays (not shown) with cops are fed into cop preparation 78 via a feed path 80 and leave the cop preparation in the direction of the winding positions on transport path 82. They leave the winding positions on transport path 84 and are either at cop preparation 78 or at a discharge path 86 (if fully unwound) is supplied.
  • the winding machine 70 is not (as in FIG. 1) connected to a single ring spinning machine, but rather to a plurality of ring spinning machines (flexible link - e.g. according to EP 344597).
  • An example of the arrangement can be found in DOS 3235442.
  • each peg tray is treated individually, and there is the possibility of treating the peg trays differently, as is the case e.g. already in EP 402630; EP 406541 and DOS 3434576 is provided in a different context.
  • the upstream machines are normally not in a position (ie they have no suitable sensors) to completely monitor or control the product.
  • the final check still takes place in the winding unit.
  • the behavior of the upstream stages is still assessed on the basis of the test results in the downstream stage.
  • this production site should be switched off. This can e.g. by means of a mobile machine, as already suggested in connection with FIG. 1. But it can also be done by the machine itself, e.g. where each production site is provided with its own match clamp that can be triggered by the machine control (e.g. according to US 4,763,467). However, it can also be carried out by an operator if appropriate instructions are given (e.g. according to WO 91/16481).

Abstract

Dans une installation de filature comprenant un métier à filer (RSM) avec un système de commande automatique (BDA) associé à ce métier à filer et une machine de traitement ultérieur (SPM) reliée au métier à filer, le système de commande automatique possède des dispositifs permettant de recueillir des données sur les états des points de filage du métier à filer. Il existe également des dispositifs servant à établir un lien entre les données recueillies sur les états et le temps machine et à transmettre les données ainsi recueillies à la machine de traitement ultérieur de telle manière qu'une commande de la machine de traitement ultérieur permette que le traitement de chaque paquet transmis par le métier à filer à cette machine de traitement ultérieur soit adapté aux données d'état produites lors de la formation de ce paquet. On obtient ainsi une exploitation plus rationnelle de la machine de traitement ultérieur et une amélioration de la qualité du produit filé.
