Definitions

  • the invention relates to a textile machine of the type specified in the preamble of claim 1.
  • Such a textile machine is known for example from US-3,381,462 AI.
  • the known thread waste device has the disadvantage that if the dimensioning of the transport channel is too narrow, the operational sequence can easily be disturbed due to a blockage. On the other hand, such a high flow velocity must be present in the transport channel that the vacuum present at the inlet openings for the thread waste is sufficient to ensure that the threads delivered continuously at high thread speeds are still safe can be sucked in and transported away, at all processing points of the texturing machine.
  • a yarn waste container device is also known, which is used in a bobbin changing device (doffer) for a modern high-speed false twist crimping machine.
  • the threads are delivered during the bobbin change through a pipe system which belongs to the bobbin changing device and is moved from this by a group of winding units to the next group of winding units to be operated.
  • the negative pressure generated by a negative pressure source which is connected to an intermediate container of the waste container device, is used to transport the threads.
  • the disadvantage here is that the negative pressure generated acts on the entire unit consisting of the intermediate container and waste container and for each change of a waste container the negative pressure source has to be switched off and the prevailing negative pressure has to be compensated in order to build it up again after the container has been changed.
  • the object of the invention is to provide a textile machine of the type mentioned in the preamble of claim 1, which is capable of sucking in the threads or thread remnants reliably even at high working or production speeds and which promotes blockage of the transport channel in the provided container without risk of malfunction ,
  • Another object is to provide a thread waste device which uses the energy sources already present on the textile machine for its operation.
  • a sufficient negative pressure is generated in the transport channel for the thread remnants and in the area of the thread processing points, where the junctions lie in the transport channel, in order to reliably detect the thread remnants and to send them to the collecting container.
  • the thread remnants are blown out into the connected collecting container, which is now not under the high negative pressure of a corresponding vacuum device. This also makes it easier to replace the collecting container when it is filled and has to be emptied, since there is no need to produce pressure compensation. Since a vacuum does not have to be re-established after a container change, the system is also always ready for operation without interruption. Blowing out the yarn waste also has the advantage that a much higher packing density of the yarn waste is generated in the collecting container. This allows larger quantities of yarn waste to be picked up without enlarging the collection container.
  • the energy supply installed on the textile machine can be used to operate the jet apparatus, which is preferably designed as an ejector device operated with a gaseous working medium, in particular compressed air from the operating network, since this is usually already provided with installation connections of the company compressed air network. Retrofitting of the textile machine with the transport system for thread remnants according to the invention can thus also be carried out in a simple manner.
  • the blasting apparatus according to the invention is particularly advantageous in terms of the investment required and its running costs, in particular in comparison to a corresponding vacuum system with the associated filter devices which are used in the transport systems according to the prior art. Finally, there is also a great advantage in that the proposed blasting apparatus is extremely low-maintenance, since it has no moving components.
  • the proposal also has a great advantage in that a waste bag can be detachably and easily replaced as a collecting container for the thread waste. When it is filled, it can be exchanged in a few simple steps and without additional tools, and it can be recycled together with the thread remnants and the thread wastes that are conveyed into it. In the meantime, the collection container saves the remaining thread residues.
  • the bottom of the collecting container can be closed at the bottom with a flap which is brought back into the operating position in which it is open after another empty rubbish bag has been attached. This can be done by the operating personnel of the textile machine by hand or by means of suitable electro-mechanical or pneumatic or hydraulic actuation devices.
  • the thread transport system has a plurality of thread injectors assigned to the processing points. Each thread injector is assigned at least one inlet opening for receiving a thread.
  • FIG. 1 shows a cross section of the end portion of a false twist crimping machine.
  • FIG. 2 shows the winding units of the false twist curling machine from FIG. 1 lying one above the other in three floors and the associated thread transport system for suctioning off thread remnants when changing the bobbin in a schematic representation;
  • Fig. 3 shows an embodiment of a blasting apparatus according to the invention in cross section including thread and thread waste bag.
  • a thread 1 consisting of several filaments is mis-twisted in the false twist curling machine 2 by a texturing unit 3.
  • This consists, for example, of several interacting friction disks, which are lined up on driven, parallel spindles at a distance from one another and, in plan view, overlapping one another, the spindle axes passing through the corners of an equilateral triangle.
  • the texturing unit 3 is driven directly by an electric motor 4, ie one of the three spindles is direct and, starting from this, the other two spindles are driven by toothed belts.
  • the rotation applied to the thread 1 by the texturing unit 3 runs from the false twister 3 back to the fixing heater 5, where the filaments are softened thermoplastic, so that the applied rotation is impressed into the thread 1. Seen in the direction of the thread run, the impressed rotation of the thread 1 is frozen on a cooling plate 6 after leaving the fixing heater 5.
  • the thread 1 drawn off by the delivery mechanism 7 at approximately the thread processing speed now runs with the heat-fixed rotation through the false twister 3 and is opened again in its outlet, ie the thread 1 is rotated in the thread running direction by the last disks of the false twister 3 in the opposite direction. Due to the previous heat treatment, the however, texture embossed in the thread is preserved.
  • the textured thread 8 is then heat-set between the delivery mechanisms 9 and 10 in the so-called set heater 11 under adjustable shrinkage conditions, ie in particular thread tension and temperature, and wound into texturing coils 12.
  • the windings for the textured threads 8 are arranged one above the other in three floors.
  • the division of a winding unit 13 thus corresponds to the division width of three texturing units 3 arranged next to one another.
  • the winding units 13 are all identical to one another. They each consist of a traversing device 15, from which the thread 8 is moved back and forth during its winding travel, a friction roller 16 for circumferential drive of the texturing coil 12 and the pivotably mounted bobbin lever 17, on which the texturing bobbin 12 or, after a bobbin change, the from above automatically supplied empty bobbin tube 18 is clamped.

  • the thread waste device 24 has a thread transport system 14 for picking up and removing the threads 8 from the processing points 31.

  • additional thread injectors (not shown) in the region of circumferentially offset thread inlet openings 19, which ensure at very high working speeds of the false twist crimping machine 2 that the threads 8 which continue to run at the speed of the delivery mechanisms 10 during a bobbin change do not accumulate and undesirable Can form windings, but are transported away via the thread transport system 14 to a thread collecting container 21 for the thread remnants.
