Definitions
- the invention relates to a device for the production of loop yarn with an air blowing texturing nozzle and with a nozzle core having at least one air supply bore, which can be driven for a rotational movement relative to a nozzle housing, the nozzle housing having a compressed air connection for the air blowing texturing.
- the loop yarn is made with air texturing nozzles.
- EP 0 088 254 The main components of the whole device are
- a radial hole for feeding the pressure medium opens into the yarn treatment channel.
- the channel has an outwardly widening, convexly curved outlet opening and a spherical or hemispherical guide body which projects into the latter and forms an annular gap with the latter.
- the outer diameter of the outlet opening advantageously corresponds to at least 4 times the diameter of the channel and at least 0.5 times the diameter of the guide body. This results in an optimal texturing effect, which guarantees a high stability of the yarn, a high degree of mixing of the individual filaments and an even loop formation.
- EP 1 022 366 now proposes to continuously drive the nozzle core for rotation in order to partially suppress the contamination. Practical tests have shown that the cleaning interval can actually be extended considerably.
- the yarn is treated with various means immediately after the spinning process.
- oily substances, anti-mold agents, calcium salts, magnesium salts and water are added to the yarn. These substances stick during operation, especially at the inlet and outlet of the yarn channel. This dirt build-up increasingly changes the flow conditions for the blown air.
- the nozzle cores must therefore be cleaned at relatively short intervals. In practice, the cleaning cycle is between one and e.g. 8 days and requires a corresponding loss of production. With a constant rotational movement according to EP 1 022 366, the cleaning interval can actually be extended to a multiple.
- EP 1 022 366 suggests rotating either the nozzle core or the entire nozzle housing.
- a drive motor is proposed for the mostly very high number of parallel yarn runs with the corresponding number of nozzle cores. This allows all of the nozzle cores or nozzle housings to be driven simultaneously with corresponding gears with a single motor. On the one hand, this is a great advantage. From a mechanical engineering point of view, however, it is also a disadvantage, since the space required for this must be created in the machine. The main disadvantage is that later retrofitting is almost impossible.
- Another problem is that e.g. with a rotating nozzle housing, the previous concept with a guide body is completely abandoned.
- the invention has now been given three subtasks.
- the device according to the invention is characterized in that the drive for the rotational movement of the nozzle core is integrated as an electrical or pneumatic drive in the nozzle housing as a structural unit.
- the nozzle housing according to the invention is characterized in that the housing is divided into two parts, with a compressed air connection on one housing part and a connection point for at least one further component on the other housing part and forming a unit as a whole.
- the inventor has recognized that it is very disadvantageous in terms of practicability in industrial textile technology practice to provide improved functions via additional structural devices.
- the previously very successful concept of the air blast texturing housing as a metal body makes further expansion difficult.
- the new solution is reflected in two solutions.
- the air blast texturing housing will continue to be designed as a unit with all essentially integrated functions.
- the basic structure with the two-part design allows for a previously unavailable expansion, the new nozzle housing concept represents a major development step in the sense of the invention with the integration of the drive.
- the new invention also allows various very particularly advantageous further designs.
- a galvanically isolated electrical contact plug connection for controlling the electric motor in low voltage is arranged on the housing.
- a pluggable compressed air connection is also arranged on the housing.
- the contact plug connections are arranged in parallel axes in such a way that both the electrical and the compressed air connection can be produced or disconnected with a plug-in movement.
- a swivel arm with a guide body which can be moved in and out is arranged in a stationary manner on the housing, so that the guide body stands still in the operating position and the nozzle core rotates relative to it.
- the new solution therefore has two advantages.
- the drive of the nozzle core means that the compressed air of e.g. 6 - 14 bar very much easier, since it can be attached in the nozzle housing.
- the guide body which is stationary with the nozzle housing, reinforces the cleaning effect through the yarn. The yarn run is forced through a narrow gap, so that with the constant rotation of the nozzle core with e.g. 5 rpm. the particularly delicate conical exit area of the yarn channel is cleaned even better.
- the outlet gap between the nozzle outlet and guide body can be optimized both in relation to the actual texturing process and to the question of cleaning.
- Another design idea is characterized in that for a plurality of nozzle cores which are in operation in parallel, the control takes place via a bus line from a central control device.
- the drive has a ratchet drive which can be driven electrically with a coil or pneumatically and is integrated in the air-blast texturing housing.
- the two-piece structure of the housing allowed, in particular to arrange the guide body in one and the nozzle core with overdrive in the other housing part. Both housing parts form a unit. This allows both the pneumatic connector and the electrical connector to be connected and disconnected at the same time.
- the nozzle core can be driven via an overdrive sleeve fixedly arranged in the nozzle housing, the nozzle core being easy to install and remove from the overdrive sleeve, and in particular the nozzle core preferably has at least one, preferably three circumferentially arranged air supply bores and the like
- Overdrive sleeve has a plurality of air holes arranged uniformly distributed around the circumference. Practical tests in industrial use had shown that special attention had to be paid to the compressed air supply when the nozzle core was rotating. The air flow must not be chopped, since appropriate pulsations have a negative effect on the quality of the loop formation. With the proposed sieve-like air supply, this problem could be solved surprisingly well.
- the air bores in the overdrive sleeve are arranged in at least two staggered rows, the compressed air being able to be supplied from the compressed air connection via an annular space in the nozzle housing.
- the nozzle core is advantageously formed in two parts and has an inner ceramic insert and an outer nozzle body, which as a unit can easily be installed and removed in the overdrive sleeve.

- the spherical guide body or impact body 11 is guided via a fastening bolt 13 into the holding head and penetrates a clamping head 14.
- the clamping head 14 has a plurality of clamping paws 1 5 rounded to the rear, which lie in a correspondingly concave shape 16 of the holding head 12.
- the fastening bolt 1 3 can be set to a desired exact position in accordance with arrow 19 and fixed by tightening the clamping screw 1 7 using a hexagon key.
- the nozzle core 26 is made for exact positioning removed from the nozzle housing, inserted a spacer gauge having the fitting shape of the nozzle core, the guide body 11 brought to a stop to the spacer gauge and the clamping screw 17 tightened in the fitted position. After reinstalling the nozzle core 26, the device is operational.
- the impact body 11 penetrates into the outlet opening 20. Not shown is the actual movement of the swivel arm 9, which in the articulation point 10 performs not only a swivel movement according to arrow 21 but also a slight extension movement according to arrow 21, so that the impact body 11 covers the surface 22 of the nozzle core 26 in the region of the outlet opening 20 not touched ( Figure 4).
- FIG. 1 a shows the nozzle housing 1 from the side of the yarn feed with a yarn guide 23.

- the direction of yarn travel is marked with arrow 49.
- Compressed air (PL) is fed into the yarn channel 25 via a plurality of injection bores 51 using the radial principle, opens the filament composite at point 52 and creates the loops in area 53 the nozzle core 26 constantly changed and thereby very effectively - especially the outlet opening - cleaned.
- FIG. 5 shows the simultaneous connection and texturing of a fancy yarn 55 and a stand-up yarn 56 and the right-angled draw-off of the textured yarn
- FIGS. 6a and 6b show an air blowing texturing unit 60 with a rotating nozzle core 26 with a pluggable air connection 61 and a pluggable electrical connection 62.
- What is particularly interesting about the solution according to FIGS. 6a, 6b and 7a and 7b lies in the parallel-axis arrangement of the two plug connections, what with the parallel axes 63 and 64 is indicated.
- the air blowing texturing unit 60 can now easily be plugged in by hand by appropriate force acting on the air blowing texturing unit for the production operation or can be released for service work perpendicular to the plane 65 without any special tools being required.
- the nozzle core can only be swiveled by the latch 27, e.g. for service work or for a change, can be installed or removed.
- FIGS. 7a and 7b show an air blowing texturing unit 60 in a schematic representation in section.
- a miniature electric motor 70 is connected directly to a corresponding miniature planetary gear 71 and transmits the rotary movement to the nozzle core 26 via a worm gear 72, 73.
- the illustration shows the nozzle core 26 being partially pulled out of an overdrive sleeve 74.
- the electrical connection is made via a galvanically isolated electrical connector 75, via which the required drive current is preferably transmitted in low voltage (below 50 volts) and in high frequency and is supplied to the electric motor 70.
- FIG. 8 shows, roughly schematically, the entire electrical control system for several electrically driven nozzle cores.
- the number of air texturing units 60 that can be operated simultaneously is unlimited and can easily be many hundreds of units.
- the power supply is supplied from a control unit 76 via a bus line 77 and via branch lines 78 to each individual air blowing texturing unit 60.
- FIGS. 9a to 9c are a particularly advantageous embodiment with regard to the compressed air supply to the Represents nozzle core 21.
- the compressed air for the air blowing texturing is supplied to the nozzle housing 1 via a space 80.
- the worm gear 73 is located in the space 80.
- the compressed air then arrives in the annular space 82 (FIG. 10a) according to arrow 81, from where it passes through a plurality of air bores 85 (FIG. 9b) into a cylindrical air distribution space 83 and from the air distribution space 83 the injection holes 51 are guided according to arrows 86.
- the air bores 51 are already part of the highly sensitive zone of the yarn channel 25, which goes up to the outlet opening 20 for the air blowing texturing.
- the rotational movement of the overdrive sleeve 74 together with the nozzle core 26 with the plurality of air holes 85 results in a constant and trouble-free passage of air, which is not the case with only one air hole 85.
- the air bores 85 are arranged in two staggered rows 88 and 89. This creates an annular, uninterrupted flow of compressed air.
- the overdrive sleeve 74 is rotatably mounted in the nozzle housing and rotates together with the nozzle core 26. In this way it is achieved that changes in the flow conditions occur despite the rotary movement of the nozzle core 26 and despite the different instantaneous positions of the nozzle core.
- the nozzle core 26 can be installed and removed by the operating personnel for yarn processing.
- the nozzle core is either pulled out of the overdrive sleeve 74 or inserted again.
- 0-rings 90 provide an airtight seal for the air distribution space 83.
- the overdrive sleeve 74 can be removed after loosening the corresponding screw connections.
- the space 80 is also sealed with O-rings 91.
- FIG. 10 a shows, in perspective, with a partial cutout, a nozzle core 26, installed in an overdrive sleeve 74 with a worm wheel 73 attached.
- the air flow is indicated by arrows 84 and 86.
- FIG. 10b shows the overdrive sleeve 74 in natural size with a scale next to it.
- the other figures are enlarged in the drawing.
- FIG. 1 1 shows a further particularly advantageous embodiment, which is based on EP-PS 1 022 366. It is proposed that the nozzle core be rotated continuously or alternately. This makes it possible to massively extend the cleaning interval.
- FIG. 1 1 shows an example of the simultaneous connection and texturing of two yarns, a yarn A and a yarn B, which are guided into the inlet 47 via thread guides 23.
- the nozzle core here consists of a ceramic nozzle core 92 and an outer nozzle core jacket 93 and is in the rotatably mounted overdrive sleeve 74, which is mounted in the drive housing 1 via ball bearings 94.
- FIG. 12 shows the two-part nozzle core on an enlarged scale.
- the ceramic nozzle core is held in the nozzle core jacket 93 by a snap-like locking mechanism 95 and is sealed by means of two seals 96. Since the ceramic nozzle core and the nozzle core casing are a unit which is fixed to one another, a large passage opening 97 is sufficient for each injection bore 51.
