Definitions

  • the present invention relates to a method for separating a sliver delivered from a spinning can to a spinning station of a spinning machine, the spinning station having a feed device by means of which the sliver is delivered from the spinning can to the spinning station and in which the sliver is clamped at the spinning station , as well as a spinning device.
  • the invention also relates to a spinning machine with a plurality of juxtaposed spinning stations and with spinning cans set up in at least one row below the spinning stations, the spinning stations each having a feed device for feeding a sliver from one of the spinning cans to the spinning station. It may be necessary on spinning machines for various reasons to separate the sliver delivered to the spinning station.
  • DE 2521 851 A1 it is therefore described to sever the sliver in a controlled manner by means of a severing device through a smooth cut.
  • a corresponding separating device should be arranged at each spinning station.
  • the remaining fiber band remnant is spun, whereby the yarn forms a thick point in the form of a fiber tuft at its end due to the smoothly cut fiber band end.
  • DE 39 28 648 A1 a can changing process is described in which sliver can changes are carried out by means of a can changing carriage.
  • the can changing carriage is designed to be able to change both the spinning cans in the front row and the spinning cans in the back row.
  • the interchangeable carriage has a cutting device.
  • yarn defects can occur.
  • the object of the present invention is therefore to eliminate the disadvantages known from the prior art, in particular to avoid yarn defects as a result of the sliver being severed.
  • the spinning point has a feed device by means of which the sliver is delivered in a delivery direction from the spinning can to the spinning station and in which the sliver is clamped at the spinning station is, as well as a Spinnvor direction. It is proposed that, in order to separate the fiber sliver, the feed device is driven counter to the delivery direction, the fiber sliver being returned by means of the feed device, and thereby the clamping in the feed device being released.
  • the spinning stations each have a feed device for feeding a sliver from one of the spinning cans to the spinning station. It is suggested that the spinning station and / or the spinning machine has a control unit for carrying out the method described above.
  • the feed device is operated against the delivery direction during production.
  • the fiber band is thereby separated from the spinning device before it enters the spinning device; there is no longer any fiber sliver residue left at the spinning station. It is therefore not necessary to remove any remaining sliver residue from the spinning point, nor can this lead to yarn defects. Since the return delivery also removes the clamping of the sliver in the feed device, the sliver that has now been separated can be completely returned to the sliver can when changing a sliver can.
  • the feed device on a rotor spinning machine is a feed device that is operated briefly against its regular direction of rotation during production for return delivery.
  • the sliver, wel Ches is clamped during operation between a feed roller of the Suitevorrich device and one of these associated feed trough, is separated here by ge immediately before entering the spinning device and at the same time conveyed out of the clamping point.
  • the clamping of the sliver in the feed device is thus released at the same time, so that the end of the severed sliver is free.
  • the process can also be used on an air-jet spinning machine.
  • the feed device is a drafting device, which is briefly driven backwards to separate the sliver, as a result of which the sliver entering the spinning device is returned.
  • the sliver is clamped in the roller pairs of the drafting system.
  • Rich device By the return of the sliver or the Antrei ben of the drafting system in the regular delivery direction opposite Rich device is the sliver immediately before its entry into the Spinning device separated and conveyed out of the drafting system by means of the roller pairs of the drafting system. This in turn at the same time releases the clamping of the sliver in the feed device, so that the end of the sliver is free.
  • a delay between the different roller pairs of the drafting system is set in the reverse order to the delay during regular production. This makes it possible to avoid a jamming of the sliver during the return delivery, which can occur, for example, at a compressor associated with the drafting system.
  • the spinning device is initially stopped before driving the Zuzhouvor direction against the delivery direction.
  • the organs of the spinning station can be controlled and shut down in a coordinated manner. Yarn errors, which could otherwise arise when the fiber band runs out, can be avoided in this way. However, this is not necessary; a thread breakage can also be generated by driving against the delivery direction.
  • the sliver is threaded out of a sliver guide of the spinning station after it has been separated. As a result, the sliver is no longer connected to the spinning machine at any point and can thereby be removed from the spinning machine in a simple manner together with the spinning can to be changed when a can is changed.
  • the sliver is severed as part of an automatic can change process.
  • an at least partially empty spinning can to be removed is removed from the spinning machine and replaced by a full spinning can.
  • the sliver can be separated reliably and residue-free, ie without a sliver residue remaining.
  • the spinning cans can This means that they can be changed without any problems, even if they still contain a remaining filling.
  • downtimes of the spinning devices which can occur when the spinning cans are idling, can be avoided.
  • the productivity of the spinning machine can be increased as a result.
  • a remaining sliver length of the fiber sliver is specified and the can changing process is initiated as soon as the specified remaining sliver length is reached.
  • the specification of a defined remaining sliver length helps both to avoid the spinning cans running empty completely and to avoid premature spinning can changes.
  • a remaining sliver length of the fiber sliver can advantageously be specified in the control unit, at which an automatic can changing process is to be initiated.
  • the spinning station has a measuring device by means of which the remaining sliver length of the fiber sliver can be determined.
  • the measuring device is in a tax-related connection with the control unit in order to initiate the automatic can change process.
  • the fiber ribbon is unthreaded by means of at least one handling device of the spinning machine.
  • the sliver can be separated from the spinning machine in an advantageous manner before the arrival of an operator or a can changer.
  • the spinning machine and / or the spinning station advantageously have at least one handling device for threading the sliver out of a sliver guide of the spinning station.
  • Handling device can, for example, be arranged on the spinning machine, in particular special at a single spinning station, and thereby in advantageously, this threading out immediately after the sliver has been returned.
  • a handling device that is arranged in the area of a spinning station and serves several spinning stations is also conceivable.
  • the spinning machine it is also possible for the spinning machine to have a movable maintenance device to which the at least one handling device is attached.
  • the handling device of the movable maintenance device can hereby preferably also thread the sliver out of the sliver guide before a movable can changer arrives.
  • the fiber sliver is unthreaded by means of at least one handling device of a movable can changer.
  • a further proposed can changer has for this purpose a handling device, for example a clamp for the sliver, for threading a severed sliver from the sliver guide.
  • the spinning machine does not need any handling devices that are either owned by the spinning station or arranged in a movable maintenance device and can thus be designed more simply and at lower cost. Only a single handling device is required on the movable can changer.
  • the at least one handling device of the spinning machine interacts with the at least one handling device of the can changer for threading out.
  • a handling device arranged in a movable maintenance device and for a spinning station's own handling device.
  • two handling devices arranged on the spinning machine could also interact.
  • a handling device in the movable maintenance device could jointly take over the threading out process with a handling device at the spinning station.
  • the sliver is unthreaded during the can change process. This is particularly advantageous if the threading out takes place by a handling device of the can changer, since this does not require any additional expenditure of time and the downtimes of the spinning stations can be kept low. Even when threading out the sliver by means of a handling device of the spinning machine, it can be advantageous to thread out the sliver only during the can change process. The can change process can also be carried out without delay in this case.
  • the handling device is provided on the can changer, it is particularly advantageous if, in order to thread the sliver out of the sliver guide, the sliver is clamped by a can gripper of the can changer. In this way, the sliver can advantageously be threaded out of the sliver guide by removing the spinning can from the spinning station.
  • a clamp is advantageously arranged on a can gripper of the can changer for this purpose, or the can gripper itself forms a clamp. It is particularly advantageous if the sliver is clamped by the can gripper on the sliver can to be removed and is pulled out of the sliver guide by removing the sliver can.
