Definitions

  • the invention relates to a centrifuge spinning / winding machine according to the preamble of claim 1.
  • the Swiss patent 548 460 describes, for example, a device in which a roving drawn off from a flyer spool, a so-called fuse, is alternately fed into two adjacent spinning centrifuges via a drafting device.
  • the device works according to the so-called two-stage centrifuge spinning process, which means that the drawn roving initially only receives part of its final rotation when it is fed into the spinning centrifuge.
  • the roving is cut and the roving end connected to the flyer spool is fed into the second spinning centrifuge.
  • the partially spun yarn is drawn off from the first spinning centrifuge and wound up on a winding device to form a package.
  • the yarn then receives its final twist. The process is repeated accordingly as soon as the second spinning centrifuge is filled.
  • the two-stage centrifugal spinning process has the disadvantage that the yarn, when it is withdrawn from the spinning centrifuge, has not yet been completed, that is to say has only a part of its final rotation. It is therefore an extremely sensitive good.
  • the yarn out of the spinning centrifuge it is therefore often impossible to avoid losses of twine due to thread breaks.
  • the usual for thread breaks Fishing "of the thread end within the centrifuge negatively affects the efficiency of the facilities concerned.
  • a roving distorted by a drafting system is first fed onto the wall of a spinning centrifuge rotating at high speed.
  • the feed speed of the fuse and the speed of the spinning centrifuge are, however, matched to one another in such a way that a spinning cake is deposited on the centrifuge wall, which consists of finished yarn.
  • a rewinding process is initiated. This means that a rewinding tube, for example held on a thread guide tube, is lowered into the spinning centrifuge and detects the rotating yarn leg emerging from the thread guide tube. The yarn cake is then wrapped on the rewinding tube.
  • the resulting spinning cop is then removed from the spinning centrifuge by a doffing device and rewound to a large-volume cheese on a downstream winding device.
  • centrifuge spinning / winding machine which after the above-described single-stage centrifuge spinning process, is described for example in DE 195 31 147 A1.
  • This well-known, longitudinally constructed textile machine has, for example, 100 arranged side by side Workplaces with at least one around a vertical axis rotating spinning centrifuge. Every spinning centrifuge is a separate doffer with a permanently installed rewinding tube assigned, each from above into the spinning centrifuge is retracted while doing so on the centrifuge wall discarded spider cake. The doffer convicted then the finished spinning cop from the centrifuge into a special suction chamber.
  • the centrifuge spinning / winding machine described above is not only relatively complicated in their construction and the training of theirs is also complex and disadvantageous Doff facility. That means the doffing facility works with a fixedly arranged on the doffing reel, what For example, with residual cops leads to problems and the The flexibility of the facility is significantly restricted.
  • the Invention based on the object, the known To improve centrifugal spinning / winding machines.
  • the inventive design of the work stations of a centrifuge spinning / winding machine with a separate storage device connected between the centrifuge spinning units and a winding device advantageously leads to a decoupling of the work cycles Spiders "and Do the washing up". That is, since the work cycles Spiders "and Spools "separated by buffering ensures that problems in the area of one of the work cycles do not immediately affect the other work cycle. It is therefore ensured that there are always enough empty tubes on the spinning centrifuges for the doffing processes and that there are always enough spinning heads on the winding device are available for the winding process. Overall, a textile machine with separate storage devices in the area of the workplaces, in particular with regard to minor malfunctions, is far less susceptible than the known devices and therefore has a higher efficiency.
  • Another advantage of the in-house storage device according to the invention can be seen in the fact that a direct assignment of the spinning heads to the spinning centrifuges on which the heads were produced is already possible via the order in which the spinning cops are fed to the winding device.
  • a complex spinning cop identification device can therefore be dispensed with in the device according to the invention.
  • centrifuge spinning units for example four or eight
  • the winding device of which normal "winding speed is significantly higher than eight times the spinning speed of the spinning units, it is possible with the centrifuge spinning / winding machine at hand to reduce the winding speed, which has a positive effect on the quality of the cheese produced.
  • the storage device is preferably designed to be stowed.
  • the storage device this makes it independent of both the transport speed their funding institutions as well as the work rhythm of the Spinning and / or winding device.
  • the storage device over at least one conveyor line on which the material to be conveyed (Package, package carrier) can be temporarily parked.
  • the conveyor line (s) forms, as in claim 3 described, on the one hand a storage path for packages and on the other hand, a waiting line for package carriers.
  • the storage section and the waiting section are e.g. drivable Belts, turntables or similar low-maintenance funds for the transport of, for example, stowable Transport plates arranged standing goods (Claim 6).
  • Centrifugal spinning units are arranged in a circle and over one or more pivoting doffing devices to be served. It is advantageous if one Doff issued operated at least two centrifuge spindles. However, it is equally possible for several For example, four centrifuge spindles have a common one Doff device to use.
  • the storage device has a storage section with an entry point for spinning bobbins and a waiting section with a discharge point for empty tubes. These two sticks are gripped by the gripping device of the doffing device in the area of the feed point or discharge point. Via these interfaces of the gripping device of the doffing device with the aforementioned transport paths of the storage device connected to the winding device, spinning bobbins can be transferred to the storage device without any problems or empty tubes can be removed from the storage device. Both the storage path for the spinning bobbins and the waiting path for the empty tubes are preferably dimensioned in such a way that several of the circulating goods transported on transport plates can be parked at the same time.
  • each job has several, in a row centrifuge spinning units arranged side by side (Claim 7).
  • centrifuge spinning units results in a particularly easy to maintain Centrifuge spinning / winding machine, because in this case all Working elements of the spinning / winding machine for the operating personnel are easily accessible.
  • centrifuge spinning units A particularly flexible connection to the centrifuge spinning units is given to the storage device if, as in Claim 8 set out, each centrifuge spinning unit separate single doff facility is assigned.
  • Such Arrangement makes it possible to arrange them preferably in series Centrifuge spinning units to immediately doff so that the Idle times of the centrifuge spindles can be minimized can.
  • the cross transport line connects the Waiting line for the empty tubes with the storage line for the Spinning bobbins (claim 9).
