Definitions

  • the invention relates to a device for air swirling a plurality of running threads and a nozzle bar for use in such a device.
  • a device for air swirling such a thread group in which the Vortex nozzles are used in an airtight manner in a flat vortex housing and are connected together to an air source.
  • the nozzle plate is arranged in a vertical plane so that the air nozzles are aligned horizontally.
  • the device has the disadvantage that sometimes threads with poor interlacing are created, but sometimes the qualitative homogeneity of the thread family is poor.
  • the invention is based on the knowledge that the thread guide in the nozzle has a significant influence on the quality of the thread and in particular the quality of the interlacing.
  • the invention therefore achieves the object of providing a device for air swirling for a group of threads which start up from a multiplicity of horizontal and vertical planes, by means of which essentially uniform passage conditions through the vortex nozzle can be created for each thread.
  • a device of the type described at the outset which is characterized in that a plurality of nozzle bodies each provided with a plurality of vortex nozzles is provided on a common support or supporting frame, the position of which can be changed relative to one another and to the thread sheet.
  • the nozzle bodies are advantageously designed as hollow bodies and the cavities are connected both to a compressed air source and to the blowing channels of the individual swirl nozzles of the respective nozzle body.
  • An advantageous embodiment is characterized in that the vortex nozzles are arranged in a plurality of horizontal bars and that the bars can be pivoted separately from one another about a horizontal axis.
  • a thread overflow rod can be arranged in front of and / or behind each bar, which extends along the bar and defines the thread path within the nozzles. These thread overflow rods can advantageously be connected to the bar and pivoted accordingly with it.
  • a preferred embodiment provides that the frame in which the individual nozzle bars are pivotally mounted can also be pivoted about a horizontal axis. This enables a further adjustment of the thread runs through the respective swirl nozzles. But in particular with this device it is also possible to ensure that the deflection of the threads as they run through the swirl nozzles is relatively small, so that the differences in the thread running length between the clamping points in front of and behind the device are also relatively small. Furthermore, the pivotability offers considerable advantages when inserting the individual threads.
  • the nozzle bars can be connected to a compressed air source by hoses.
  • the frame is formed at least one of the vertical side pieces as a hollow profile and is connected to the compressed air network, the individual beams being connected to the hollow profile, preferably being connected to the hollow profile via their hollow pivot axes .
  • external air connections are avoided, which are a hindrance to the large number of threads to be threaded and guided.
  • the air is preferably supplied to the frame in the lower crossmember, which in this case is also designed as a hollow profile.
  • a nozzle bar which can be used in particular in such a device, is such that the bar has an upward-facing, carefully planed surface on which a top beam with a congruent, also planar surface rests. Thread guiding grooves are machined perpendicular to the longitudinal axis of the thread in one of the two surfaces. When the top beam is lifted off, a thread can easily be inserted into each of these grooves. By covering the grooves with the cover beam, each groove forms a thread channel which is closed all around. Each groove is connected via a branch duct to an air duct which extends in the longitudinal direction of the nozzle bar and which - e.g. as described above - is supplied with compressed air.
  • the thread guide channels can e.g. be rectangular grooves that are made by milling in the flat surface of the nozzle bar. This has the advantage that the cover bar does not require any further processing apart from the surface processing.
  • grooves can also be made in both flat surfaces, which mesh with one another when the top beam is attached. In this way, thread channels with a circular cross-section can be produced, in particular, by firmly clamping the lower beam and the cover beam to one another and then introducing the nozzle bores in the seam area of the plane-worked surfaces.
  • the grooves can also be made in the deck beam. In this case, the lower bar only has the surface machining of its surface, with branch channels opening into the air channel in this surface with the division of the grooves made in the top bar.
  • This construction of the nozzle bar enables the air nozzles to be very closely spaced e.g. only 5 mm next to each other, so that a device for air vortex treatment of a thousand threads builds relatively small.
  • the stitch channels are attached in such a way that the air flow exiting into the thread channels has a movement component in the direction of conveyance of the threads.
  • a row of nozzle bodies is attached to an essentially horizontally extending air supply bar, each nozzle body has a number of swirl nozzles, the thread channels of which run parallel to one another and whose blowing channels are connected to a common air supply.
  • the individual vortex nozzles can be arranged in the nozzle bodies in one or more rows parallel to one another, the planes parallel to one another running essentially perpendicular to the air supply bar through the nozzle axes of the individual rows.
  • the individual nozzle body advantageously has at least four and preferably at least six vortex nozzles arranged with a small mutual distance between the thread channels; the distance between two adjacent thread channels is advantageously at least 1.5 mm and at most 15 mm, with the row spacing being reduced
  • the thread channels of adjacent rows can be arranged offset from one another.
  • the individual nozzle body consists of a housing and a housing insert which fits into the housing and accommodates the individual vortex nozzles.
  • the blowing channels of the individual swirl nozzles of a nozzle body are connected to a common air supply in the nozzle body.

In its side walls lying transversely to the thread run, it contains bores for the tightly packed accommodation of insert nozzles, the ends of which are fitted into the bores of the side walls; their blow channels open into the box interior, which in turn is connected to the interior of the air supply beam.
  • the rows of nozzles are offset from one another by half a distance between two insert nozzles lying next to one another in the same row; the individual insert nozzles are each provided with a rectangular plate on its front, the edge lengths of which are matched in such a way that the plates abut one another with essentially no space when the nozzles are fitted. If the rectangular plates are offset asymmetrically on the edges for mutual overlap, it is possible to lock all insert nozzles together using only one clamp and to align them unambiguously with regard to the position of their blowing channels during assembly.
  • the nozzle bodies in their side walls lying parallel to the general thread run have bores for receiving insert nozzles which extend essentially parallel to the thread run.
  • the bores and the insert nozzles have threading slots extending from the side walls over the length of the insert nozzles, while the air supply to the individual nozzle inserts takes place via connecting ducts starting from the individual bores to the air-guiding interior of the nozzle body.
  • the threading slots in the nozzle body can be covered by suitable means after the threads have been inserted, but the threads can also be prevented from escaping by rotating the nozzle inserts in the bores, so that the threading slots are closed.
  • the threading slot and blow hole in the insert nozzle are arranged so as to be offset relative to one another on their circumference in such a way that in the threading position the blowing channels and in the working position the threading slots are covered by the hole wall.
  • the individual insert nozzle consists of an outer tube which is stuck in the bore of the nozzle body with a threading slot and an inner body which can be rotated in the tube and which has provisions for thread take-up.
  • the stuck tube also has a blowing bore that matches the connecting channel of the bore in the nozzle body.
  • the inner body can be solid or also a tube.
  • a thread guide groove extending over its length is introduced into its outer surface and has any, but preferably rounded, cross section.
  • the inner body is an inner tube which is also provided with a threading slot.

In the working position, the inner body 302 is rotated so that the blow channel 108 meets the groove 303 or 304. The inserted thread 311 is carried along when the inner body 302 rotates.
  • FIG. 3 Another example of a threadable swirl nozzle is shown in the upper example of the right vertical nozzle row.
  • a slotted tube is firmly inserted into the nozzle bore 136. His slot coincides with it the threading slit 305 of the nozzle body 103.
  • An inner tube 307 slotted on a surface line is rotatably inserted in the tube 301. In the position shown, in which the slot of the inner tube 307 covers the threading slot 305 of the nozzle body or tube 305, the thread can be inserted into the inner tube 307.
  • the threading slot 305 is closed and the slot of the inner tube is made to overlap with the blowing channel 306.
  • the two lower examples of the right row of nozzles show a simplified version.
  • the outer tube 301 has been omitted.
  • An inner tube 308 rotatable in the housing bore 136 has a slot 310 which extends over its length and is used for threading, and also has a blow hole 309. Both are offset from each other, for example by about 90 °.
  • the slot 310 of the inner tube 308 is in agreement with the threading slot 305 of the nozzle body 103.
  • the blow hole 309 of the inner tube and the blowing channel 306 of the nozzle body coincide and the slot 310 of the inner tube is through the wall of the bore 136 covered. 13 shows the two situations with one another.
  • the nozzle bodies In order to make room for the lateral threading, the nozzle bodies must be moved apart in the area in which the insert nozzles 104 are located.
  • the nozzle body 103 has a lateral widening 312 on its foot part, so that the seal with respect to the air supply bar 101 is also ensured here.
  • the nozzle body shown in Fig. 13 is e.g. also fastened by means of a dovetail guide and a claw (see e.g. Figure 6A).
  • the embodiment of the nozzle body according to FIG. 13 has the advantage on the one hand that the threads can be inserted easily. Another advantage also lies in the fact that the vortex nozzles can be separated from the air supply individually by rotating the inner body 302 or inner tube 307, 308 and laid dead. When using such a nozzle body, a particularly simple adaptation of the device to the desired number of threads is therefore possible.
