Definitions

  • the present invention relates to a method for operating a textile machine with a plurality of juxtaposed workstations, wherein the workstations as working members have at least one spinning station for producing the thread and / or a winding device for winding the thread onto a spool. Furthermore, the workstations own work handling organs for re-spinning the thread or for connecting two thread ends.

  • every job is capable after an interruption the production to independently re-spin the thread.
  • the problem of waiting times and the associated loss of production can be avoided thereby.
  • such a machine equipped with single-user automation is comparatively expensive.
  • the design effort is high due to the large number of components to be arranged per workstation.
  • the EP 0 311 987 A1 describes a piecing device on a spinning machine, which has for re-spinning a thread a winding device with a winding roller, a return device with a suction nozzle, a piecing and other handling elements, by means of which the thread can be submitted to the individual organs of the piecing.
  • the piecing is arranged in a conventional manner in a movable maintenance device, but may also be provided individually for a spinning position.
  • the EP 1 970 475 A2 describes a spinning machine with such a device for automatically piecing a thread on an open-end spinning machine, which may be provided either in a movable maintenance device or at each individual workstation.
  • the piecing device has a number of handling members for re-spinning the thread.
  • a suction nozzle is also provided.
  • the object of the present invention is to propose a method and a textile machine, by means of which even in the event of unforeseen interruptions of production, the thread end can be quickly fed to the piecing process.
  • the workstations In a method for operating a textile machine with a plurality of workstations arranged side by side in the longitudinal direction of the textile machine, the workstations have at least one spinning station with a spinning device for producing the thread and / or a winding device for winding the thread onto a bobbin.
  • the workstations own work handling organs for re-spinning the thread or for connecting the thread ends.
  • a coil-side thread end is provided in a defined receiving position at the workstation.
  • the coil-side end of the thread is picked up by the working organs of the workstation, in particular the workstation's own handling organs, cut to length, cut to length, prepared for re-spinning and spun.
  • a textile machine has a plurality of workstations arranged side by side in the longitudinal direction of the textile machine.
  • the jobs contain as working organs in each case at least one spinning station with a spinning device for producing a thread and / or a winding device for winding the thread on a spool, and in both cases several workstation own handling organs for re-spinning the thread.
  • a coil-side thread end can be picked up from a defined picking position, cut to length, prepared for piecing back and spun or connected to the second thread end.
  • the textile machine has at least one in the range of several jobs of the textile machine movable yarn-searching device, which has a vacuum-pressurized suction nozzle for searching a accumulated on the coil yarn end. Furthermore, a transfer member is provided for transferring the thread end of the suction nozzle in the receiving position at the working place, from which the thread end by a working organ, in particular a working-own handling member, is receivable.
  • the workstations With the method described or the textile machine described, it is possible to provide the workstations largely self-sufficient, so that they can perform the piecing process or connection process, eg. Splicing process, independently and without waiting in most cases. Since at an interruption of production, the thread end is always provided in the defined receiving position, from which it can be taken over directly by work organs of the workplace, can be dispensed with a workstation own thread search device. This results in a significant cost advantage over a complete single-user automation and a structural simplification of the individual jobs, since there is no space-intensive thread search device must be accommodated.
  • the movable yarn-finding device which can be fed to several workstations and to feed it to the reattachment. Since the movable between multiple work stations and forth thread search device is reduced to only one or two functions, namely the thread search and possibly the transfer to the spinning station, compared to a conventional maintenance facility as well as compared to a complete single-user automation significant cost advantages. In addition, even if at several jobs at the same time a thread break must be repaired, the waiting times are on the thread-seeking device can be significantly reduced because they only need to visit the thread and handed over to the spinning unit. The next job can thus be operated much faster.
  • the thread end is spent by means of a transfer member of the thread-seeking device in the receiving position at the workplace.
  • the at least one transfer element is correspondingly arranged on the thread search device.
  • the thread search device includes in this case as working organs only a suction nozzle, a transfer member and possibly also a thread cutting device.
  • the transfer member may for example be designed as a pivoting arm, movable hook, linearly movable or backdrop-guided feeder or as a pneumatic transfer member.
  • the thread end can thus be passed through the thread-seeking device directly to the job or the work organs of the job. In principle, however, it is also conceivable to arrange a transfer member at the work station, which then takes over the thread end of the suction nozzle and transferred to the receiving position.
  • the receiving position from which the thread end is received by a working organ, in particular a work-own handling element, preferably in the yarn path between an output of the spinning station and the winding device, in particular between the output of the spinning station and a take-off device of the spinning station.
  • a working organ in particular a work-own handling element
  • This area of the job is easily accessible, so that the thread end can be transferred by the thread-seeking device or the transfer member well into this receiving position.
  • the workstation is shut down in a controlled manner or can be stopped in a controlled manner.
  • the work organs of the workstation can be controlled and coordinated with each other to decelerate to a standstill, so that the thread end eventually stops in the defined receiving position and does not run on the coil. Any waiting times on the thread-seeking device are hereby further shortened, since this is only needed in the case of unplanned interruptions of production, in which the thread end runs onto the spool.
  • the thread-seeking device spends the thread end when it is being brought into the receiving position into the area of action of a pneumatic working member, in particular a pneumatic handling member of the workstation.
  • a pneumatic handling member is usually provided at the workstations anyway to be able to fix the thread end during piecing or to form a thread reserve.

  • the thread end for example, through the exhaust nozzle of the rotor spinning device be received or in the case of an air-spinning machine through the air-jet nozzle.
  • the thread end can thereby be transferred very quickly through the thread-seeking device to the job, so that waiting times are further reduced.
  • the thread-seeking device at the same time inserted the thread end when moving into the receiving position in the take-off device of the job and / or in a yarn guide of the winding device and / or in a yarn monitoring device.
  • the thread end is thus spent directly through the thread-seeking device in a position in the threadline, in which it would be even after a controlled shutdown of the job. Additional handling facilities at the workplace are therefore not required.
  • the thread end is passed through the thread-seeking device only to a pneumatic handling organ and from there by further work-own handling organs in the withdrawal device and / or in the yarn guide and / or in the yarn monitoring device is inserted.
  • the thread-seeking device is movable in the longitudinal direction of the textile machine along a plurality of workstations arranged next to one another. It is again advantageous if the thread-seeking device can be moved by means of its own traction drive. However, it is also conceivable to arrange a drive for the thread-seeking device on the textile machine and to connect the thread-seeking device to the drive by means of a coupling element, for example a belt drive. Such a movable thread search device can be made particularly space-saving, so that the arrangement of the working organs of the job is thereby structurally easier.
  • the textile machine is provided as a double-sided textile machine
  • such a thread search device which can be moved in the longitudinal direction of the textile machine can be designed in a simple and space-saving manner if it can be moved centrally between two longitudinal sides of the textile machine.
