Definitions

  • the invention relates to a method or a device for operating an automatic cheese winding machine, which has a plurality of work stations on which spinning cops, which have relatively little yarn material, are wound into large-volume cheeses and which has a bobbin and tube transport system in which in a vertical orientation arranged on transport plates, spinning cops and empty bobbin tubes are conveyed, is connected to a ring spinning machine, which in turn is equipped with a large number of spinning stations for the production of spinning cops, the number of work stations of the cross-winding machine and the number of spinning stations of the ring spinning machine being coordinated with one another in terms of production.
  • Ring spinning machines on whose workstations spinning cops are created, which usually have high-quality yarn material, have been known for a long time and are described in detail in numerous patent documents.
  • Such textile machines have a large number of identical work stations designed as spinning stations on their two longitudinal machine sides, which in turn each have different work elements that are either stationary or vertically displaceable.
  • This means that such spinning stations each have, for example, a stationary drafting system for drawing the feed material provided by feed spools and have a rotatably mounted ring spinning spindle that is integrated into a stationary spindle bank.
  • various devices for example each mounted in a vertically displaceable manner, which are used to hold spinning rings and ring runners, to hold balloon constriction rings and to hold thread guides.
  • These vertically displaceably mounted components of the ring spinning machine which are generally designed as machine-length benches, are controlled by means of a corresponding drive mechanism according to a predeterminable spinning program and, in conjunction with the ring spinning spindles rotatably mounted in the spindle banks, ensure that from a template material, usually flyer bobbins, which hang on a template material gate arranged above the spinning points of the ring spinning machine, spinning cops are manufactured.
  • the spinning cops created on the workstations of such ring spinning machines which contain relatively little yarn volume, are lifted together from the ring spinning spindles on at least one long side of the machine after their completion, which often takes several hours depending on the yarn number, in a so-called doffing process by a bobbin changing device and in a vertical orientation , placed on transport plates positioned in front of the spinning stations.
  • the temporarily stored empty bobbin tubes which are required for a new spinning process on the ring spinning machine, are positioned on the ring spinning spindles of the ring spinning machine.
  • the transport plates with their attached spinning heads are then immediately transported to the workstations of a downstream cross-winding machine, where they are wound into large-volume cross-wound bobbins as quickly and properly as possible.
  • the workstations of such automatic cross-winding machines have various special bobbin handling or thread processing devices that enable the spinning cops to be rewound properly.
  • the work stations of such automatic cross-winding machines for example, each have a so-called unwinding position in the area of their transverse transport path, in which a spinning cop can be positioned in a functionally appropriate manner for winding onto a cross-wound bobbin.
  • Such workstations also have a winding device in which cross-wound bobbins are rotatably mounted during their production.
  • Such winding devices each have a pivotally mounted bobbin frame for rotatable mounting and a bobbin drive roller for rotating a cross-wound bobbin.
  • such winding devices are each equipped with a thread traversing device which traverses the thread that is removed from the spinning cop during the winding process and runs onto the cheese.
  • Such workstations are usually also equipped with a thread tension sensor, a thread tensioner and an electronic thread cleaner, all of which are connected to a workstation-specific control computer, which in turn is also connected to the central control unit of the automatic cheese winder via a machine bus or the like.
  • a thread removed from the spinning cop runs through an electronic thread cleaner on its way to the cheese, which continuously monitors the running thread for thread errors during the rewinding process and ensures that they are detected Thread defects can be cleaned out immediately and replaced with thread splices that are almost identical to the thread.
  • the transport plates which are positioned in the unwinding position of the automatic cross-winding machine's workstation during the rewinding process, are removed from the unwinding position as soon as their spinning cop is unwound into an empty bobbin tube and are immediately transported back to the ring spinning machine via the logistics device of the automatic cross-winding machine and the bobbin and tube transport system.
  • the invention is based on the object of developing a method and a device for operating a composite ring spinning machine/cross-winding machine, with which it can be prevented that the time of the next doffing process of the ring spinning machine has to be postponed because too Few transport plates filled with empty bobbin tubes are positioned in front of the spinning stations of the ring spinning machine.
  • This object is achieved according to the invention in that during the spinning process of a ring spinning machine, the current number of spinning cops unwound at the workstations of the cross-winding machine, which appear as empty bobbin tubes on transport plates, is constantly monitored are returned to the ring spinning machine, is recorded and, in addition, it is determined how many of these empty bobbin tubes arranged on transport plates will still be returned by the next doffing process of the ring spinning machine and that if the production process on the cross-winding machine gives rise to fears that there will be a lack of empty bobbin tubes Transport plates lead to a loss of production, a special reloading station intervenes to support the material flow of the cross-winding machine.
  • the method according to the invention has the particular advantage that the central control unit of the cross-winding machine is always informed about the current winding performance of the workstations and can intervene immediately to provide support if necessary. If, for example, the central control unit determines that the workstations of the automatic package winding machine are unlikely to be able to provide the required number of empty bobbin tubes arranged on transport plates until the next doffing process of the ring spinning machine, it intervenes in the material flow of the automatic package winding machine to the extent that it creates a special, advantageously in The reloading station arranged in the logistics device of the cross-winding machine, preferably in the area of the tube return path, is activated. This reloading station then ensures that the spinning cops are unloaded from a number of transport plates that correspond to the calculated shortage rate and that carry the spinning cops and are replaced by empty bobbin tubes.
  • the central control unit determines how many transport plates equipped with empty bobbin tubes are expected to arrive in the logistics facility of the ring spinning machine by the start of the next doffing process of the ring spinning machine and can be positioned in front of their spinning stations.
  • this shortfall is determined by means of an in the area of the logistics facility of the cross-winding machine installed transfer station.
  • the transfer station lifts a number of spinning cops corresponding to the expected shortfall rate from their transport plates and transfers them to a transport container.
  • the transfer station then replaces the removed spinning cops with empty bobbin tubes. In this way it is ensured that at the time when the doffing process of the ring spinning machine is to be started, the required number of transport plates equipped with empty bobbin tubes are always positioned in front of the spinning stations.
  • the device for carrying out the method described above advantageously has a sensor device on the input side of the cross-winding machine, preferably in the area of one of the conveyor belts of the logistics device of the cross-winding machine, which is connected to the central control unit of the cross-winding machine via a signal line.
  • the sensor device counts the number of incoming transport plates equipped with empty bobbin tubes and passes this information on to the central control unit of the automatic package winder.
  • a reloading station is installed, which can be activated if necessary by the central control unit of the cross-winding machine.
  • the central control unit of the cross-winding machine which is not only informed about how many spinning stations the associated ring spinning machine has, and which therefore knows how many transport plates equipped with empty bobbin tubes are required in front of the spinning stations of the ring spinning machine when the next doffing process is initiated, but which has also determined how many transport plates equipped with empty bobbin tubes will actually be positioned in front of the spinning stations of the ring spinning machine if no additional measures are taken, activates the reloading station so that it processes a number of transport plates corresponding to the shortfall rate by placing full spinning heads from the transport plates and places empty bobbin tubes on the transport plates.
