Definitions
- the invention relates to a spinning device for producing a thread by means of a circulating air flow according to the preamble of claim 1.
- Air-spun devices for producing textile threads are known in various embodiments and described in the patent literature.
- an air-spinning device in which a sliver warped in an upstream drafting system is introduced through a nozzle block in an air spinning device and passes through a sliver guide, which also acts as a twist stop, into the inlet opening of a spinning spindle which is rotated during the spinning process and acted on by a drive belt.
- a sliver guide which also acts as a twist stop
- the free fiber ends are wound around the conically shaped spindle head of the spinning spindle by means of a circulating air flow and wrap during retraction of the thread in the spindle spirally around the so-called core fibers. That is, the core fibers together with the so-called Umwindemaschinen form a new thread.
- a disadvantage of this known air spinning device is that the device rotates due to its stored, driven spinning spindle is relatively maintenance-intensive.
- the fiber sliver to be spun is introduced into the air-spinning device via a sliver guide and a nozzle block and enters the inlet opening of a stationary, hollow spinning cone. That is, the spinning cone of this known air spinning device is not rotatably mounted, but firmly connected to the housing of the air spinning device.
- the sliver is exposed in the region of the inlet opening of the spinning cone 'a circulating air flow, which lays the free fiber ends of the sliver around the head of the spinning cone'.
- the free fiber ends loop in this device as spiral so-called Umwindemaschinen to the core fibers and thereby form a thread in this device.
- Air spinning devices according to DE 199 26 492 A1 are characterized mainly by a relatively simple structural design and are relatively low maintenance. However, it has been found that in such air spinning devices with a fixed spinning cone, although this is made of highly wear-resistant material, preferably a technical ceramic material, there is a risk that it will wear over time in certain areas of the head of the spinning cone ', which have a negative effect on the functioning of the device.
- the invention has for its object to improve air spinning devices with a stationary during the spinning spinning spinning cone to the effect that the life of the devices, in particular the life of the highly stressed spinning cone 'is significantly extended.
- the inventive construction of an air spinning device with a spinning cone which is adjustable with respect to its installation angle, has the advantage that during the period of use of the spinning device in a simple manner, the position of the spinning cone 'changed its bearing arrangement several times and can be prevented so that it selectively to overstress of the spinning cone material, which would lead to premature wear of the spinning cone.
- the spinning cone by repeatedly rotating the spinning cone about its longitudinal axis, preferably by one or more angular degrees (e), for example, coincidentally in the course of a spinning interruption, at each spinning interruption or at periodic intervals, the impact of introduced through the blowing nozzles, in the area of the head on the spinning cone impinging air streams, which are primarily responsible for the increased wear, are gradually distributed over the entire circumference of the spinning cone '.
- angular degrees e
- the spinning cone for example, via a clearance fit rotatably mounted in the rear bearing housing of the outer casing of the air spinning device and, if necessary, easily detachable, set via a permanent magnet assembly in the desired installation angle position on the outer housing.
- a relatively simple and robust construction on the one hand ensures a secure fixation of the spinning cone 'during the spinning process and allows the operator on the other hand, the installation angle position of the spinning cone' easily, preferably event or time related but also random to adjust.
- the adjustment of the installation angle position of the spinning cone ' which is preferably only a few degrees, in an advantageous embodiment by the operator by hand.
- a manually adjustable spinning cone is on the one hand inexpensive to manufacture and on the other hand easy to operate by the operator.
- the spinning cone also, as described in claim 4, a mark from which the respective installation angle position of the spinning cone 'in the bearing assembly is easily recognizable.
- a marking is, for example, by a simple comparison of the installation angle of the respective spinning cone 'with the installation angle position adjacent Spinnkoni, immediately detectable whether the spinner cone in question was already rotated in its new angular position or whether so far failed to turn this spinning cone in the new position. That is, such a mark facilitates the uniform adjustment of the installation angular positions of Spinnkoni considerably.
- the marking is preferably arranged on a collar, which is arranged at the rear end of the spinning cone 'rotationally fixed to the spinning cone and formed so that the spinning cone with respect to its installation angular position can be easily adjusted manually.
- the spinning cone has, as described in claim 6, a device which can be actuated by an automatically operating control unit.
- This device for example, arranged on the outer circumference of the adjusting ring teeth can be acted upon by a corresponding handling device of the operating unit. That is, the automatically operating control unit, preferably a along the workstations of the textile machine patrolling the operator (Anspr.7) can set by means of a corresponding handling device, the installation angle position of the spinning cone 'defined and change anytime as needed.
- the air-jet spinning machine 1 shown in front view in FIG. 1 has a multiplicity of workstations 2 arranged in a row next to one another and a drive unit 13 on at least one end of the air-jet spinning machine 1.
- Each of the work or spinning stations 2 of the textile machine 1 has a sliver source, for example a sliver can 3, a drafting device 4, an air-spinning device 5, a thread withdrawal device 6, a yarn cleaner 7 and a thread-changing device 8.
- the Fadenchangier listening 8 ensures that the manufactured in the air spinning device 5 thread is wound in intersecting layers on a package 9.
- the cheese 9 is, as usual, held in a (not shown) creel and is rotated by a (also not shown) coil drive.
- the spinning stations 2 of the textile machine 1 are supplied by an automatically operating operating rotor 10 which, guided on rails 11, 12, can be moved along the spinning stations 2.
- FIG. 2 shows the air-spinning device 5 according to the invention, the drafting device 4 upstream of the sliver running direction R and the downstream yarn withdrawal device 6.
- the air spinning device 5 is shown in section.
- the air-spinning device 5 essentially consists of a two-part outer housing 14, 15, an expansion housing 16, a nozzle block 17, a sliver guide and twist stop device 18 and a hollow spinning cone 19.
- the expansion housing 16 forms in conjunction with the front housing part 14 of the outer housing a front annular space 20 which is connected via a pneumatic line 21 to a pressure source 22 and in conjunction with the rear housing part 15 of the outer housing an expansion space 28th While the expansion space 28 is connected via an air outlet opening 29 to the atmosphere, the annular space 20 is pneumatically connected continuously with Blas Kunststoffdüsen 23, which are arranged in the nozzle block 17.
- the blowing air nozzles 23 are directed tangentially in the region of the inlet opening 35 of the spinning cone 19 in such a way on the head 24 of the spinning cone 19 that a rotating air flow is established.
- the spinning cone 19 is further supported by a bearing assembly 30, which is arranged in the rear wall 31 of the rear housing part 15, about its central longitudinal axis relative to the outer housing 14, 15 rotatably supported.
- the spinning cone 19 which is preferably made of a highly wear-resistant material, such as a technical ceramic material, also has, seen in sliver R direction, on the output side a collar 32 with a marker 34.
- the adjusting ring 32 which is made of a ferromagnetic material, preferably steel, is fixedly connected to the spinning cone 19 and corresponds to one or more permanent magnet (s) 33 which is / are inserted into the rear wall 31 of the housing part 15.
- the stockpiled in a spinning can 3 sliver 25 passes through on its way to the cheese 9, first the drafting system 4, where it is relatively distorted.
- the drawn sliver 25 is transferred into the area of the inlet opening 27 of the air spinning device 5 via the pair of delivery rollers 26 of the drafting system 4 and is sucked into the air spinning device 5 under the influence of a vacuum flow prevailing there.
- the fiber sliver 25 passes through the sliver guide and swirl stop device 18 and the nozzle block 17 to the inlet opening 35 of the hollow spinning cone '19 and is drawn by the formed inside the spinning cone' 19 thread 36 into the spinning cone 19.
- the sliver 25 is exposed to the influence of a rotational flow in the region of the head 24 of the spinning cone 19. That is, after leaving the Faserband Installations- and twist stop means 18, the rear, free ends of the edge fibers of the sliver 25 are exposed to the action of an emerging from the Blas Kunststoffdüsen 23 of the nozzle block 17 air flow that they are lifted or released from the sliver 25.
- the front ends of the fiber are not detached because they are already trapped by binding fibers and inserted into the hollow spinning cone 19.
- the detached from the sliver 25 free fiber ends are wound by the rotating air flow around the conical head 24 of the spinning cone '19. Due to the continuous movement of the sliver 24 in sliver direction R, the rear free end of the fibers 24 is continuously drawn into the hollow spinning cone 19, wherein the edge fibers are helically wound around the core fibers of the sliver 25. The resulting thread 36 is pulled over the thread withdrawal device 6 from the air spinning device 5 and then wound into a cheese 9.
- the spinning cone 19 is rotatably supported in the rear housing part 15 of the outer housing of the air spinning device 5 in a bearing arrangement 30, for example a simple clearance fit, and can be fixed magnetically in its respective mounting angle position during the spinning process. That is, in contrast to known air spinning devices, in which due to a fixed nozzle block and a fixed spinning cone 'always the risk that the spinning cone is permanently worn at exposed points extremely exposed in the inventive air spinning device 5 of the spinning cone 19 with respect to its installation angle position become.
- the spinning cone 19 can optionally, for example periodically at predetermined time intervals, in a spin interruption at random or at each spin interruption, each twisted by a few degrees in its storage and thereby the stress of the spinning cone '19 by the air streams from the Blas Kunststoffdüsen 23 by the around the head of the spinning cone 'looping edge fibers are gradually distributed over the entire circumference of the spinning cone head, which has a very positive effect on the life of the spinning cone' 19.
