Definitions
- the invention relates to the processing of threads made of a thermoplastic material and relates to a method and a device according to the preambles of the corresponding independent patent claims for the continuous texturing of threads made of a thermoplastic material.
- the described devices essentially consist of a texturing nozzle with a conveying channel and a nozzle outlet opening and a drivable plug conveyor roller with a pair of lateral guide means running around its circumference, for example a pair of needles (needle roller).
- the texturing nozzle is arranged relative to the plug conveying roller in such a way that the conveying channel or at least the end of the conveying channel carrying the nozzle outlet opening runs essentially tangentially to the plug conveying roller and projects with the nozzle outlet opening between the rows of needles.
- the thread runs through the conveying channel against the nozzle outlet opening by a fluid flowing under pressure through the delivery channel -? ,
- the conveyed medium relaxes and the thread impacts a plug that has formed between the rows of needles from the thread that has already emerged from the nozzle outlet opening.
- the plug is conveyed away from the nozzle outlet opening at a plug speed by the rotary movement of the plug conveyor roller (needle roller), the plug speed being lower than the thread speed in the conveying channel.
- the plug runs from the nozzle outlet opening over a sector (plug sector) of the plug conveyor roller, guided by the rows of needles and slightly spaced from the circumferential surface of the plug conveyor roller, and is removed from the plug conveyor roller onto a cooling element at the end of this sector by a plug detaching agent, for example by a stationary detaching wedge ment, for example, a cooling drum.
- a plug detaching agent for example by a stationary detaching wedge ment, for example, a cooling drum.
- the texturing nozzle usually having a plurality of conveying channels running parallel to one another and the plug conveying roller having a plurality of pairs of lateral guide means, for example pairs of needles, running parallel to one another.
- thermoplastic threads in such a way that the drawing in, in particular the drawing in of a plurality of parallel ones Threads, easier and safer.
- the operation should not be influenced in any way.
- Figures la to c an exemplary embodiment of the device according to the invention for the continuous texturing of a thread, as a very schematic section along the thread / plug course to explain the method according to the invention using a stationary thread guide with a guide slot (Figure la: operation; Figure lb: first Retraction phase; Figure lc: second
- Figure 2 is the same as Figures la to lc, using a movable
- Figure 3 shows part of the embodiment according to Figures la to lc in more detail, in the same representation
- FIG. 4 shows a plan view of an exemplary, stationary feed thread guide for the device according to FIGS. 1 a to 1 c;
- FIG. 5 shows a plan view of an exemplary, movable feed thread guide for the device according to FIG. 2;
- FIG. 6 shows a further, exemplary embodiment of the device according to the invention, likewise cut along a thread / plug course;
- FIG. 7 section (according to section line I-I in FIG. 6) transverse to the course of the thread through exemplary embodiments of needle roller and detaching means with thread guide grooves;
- FIGS. 8 shows a further embodiment of the device according to the invention in the same representation as FIGS. 3 and 6.
- Figures la to lc show an exemplary embodiment of a device for continuous texturing in different phases: Figure la in the operating phase, Figure lb in a first pull-in phase and Figure lc in a second pull-in phase.
- the device essentially consists of a texturing nozzle 1, a plug conveyor roller, for example a needle roller 2 (described, for example, in European Patent No. 310890 by the same applicant), a plug detaching agent 3, for example a detaching wedge 31 and a detaching channel 32 adjoining it, and one Plug coolant, for example a cooling drum 4, which can rotate in the two directions indicated (drawn and dashed).
- a thread guide 5 there is a thread guide 5.
- the figures represent Cuts along the thread / plug course.
- the thread guide is also cut accordingly (section line II-II in Figure 4).
- the texturing nozzle usually consists of two parts 1.1 and 1.2, advantageously the part 1.1 arranged closer to the needle roller 2 being stationary, the other part being movable, such that the texturing nozzle is suitable for the Feed can be opened.
- Figure la shows the thread / plug course during operation.
- the thread F runs through the closed texturing nozzle 1.
- the thread leaves the texturing nozzle 1 at the nozzle outlet opening 11.
- a plug P is formed, which is guided by the pairs of needles such that it does not touch the bottom of the needle roller.
- the plug is conveyed further by the rotation of the needle roller 2, while it is held laterally by the rows of needles 21.
- the detachment wedge 31 and the detachment channel 32 (if one is provided) move the plug P away from the needle roller 2 against the cooling drum 4, this either in a sense opposite to the direction of rotation of the plug feed roller (variant shown in solid lines) or in the same direction of rotation how the plug conveyor roller (variant shown in dashed lines) can rotate.
- the illustrated, exemplary embodiment of the thread guide is on Fixed plug channel 32 and has a corresponding plug passage opening 52 or recess for the passage of the plug.
- a single thread F can be textured, as shown in the figure, or, as usual, it is parallel to the thread / plug course shown (in the figure above and / or below the paper plane) ) further thread / plug courses arranged.
- Figure lb shows a first pull-in phase.
- the thread F is placed in the open texturing nozzle 1 with the aid of a suction gun.
- the thread lies against a first thread guide 12 arranged at the entrance of the texturing nozzle, which is designed, for example, as a guide pin with a groove for the thread, the groove being aligned with the conveying channel in the texturing nozzle.
- the thread has a course Fl, for example.
- the thread is moved against the plug feed roller 2 with the aid of the suction gun.
- appropriate guide means must ensure that the thread has a course with which it does not come into conflict with the needle rows.
- This guide function is performed on the one hand by the first thread guide 12 and, for example, by the stationary thread guide 5.
- the thread guide 5 has a guide slot arranged parallel to the pair of rows of needles and centered thereon. - / -
- the thread guide is arranged in such a way that the thread runs through this slot when it has a course F.2 or is moved closer to the plug feed roller.
- the thread course F1 transverse to the thread movement (out of the paper plane) from the first thread guide 12 depends only on the position of the movable suction gun, that is to say is not exactly determined, the thread course is • F.2 between the thread guide 12 and the The feed guide 5 is precisely determined and aligned precisely with the conveying channel in the texturing nozzle and the plug channel formed by the rows of needles.
- the guide slot of the thread guide 5 extends somewhat over these tangents on the side thereof facing away from the plug feed roller.
- FIG. 1c now shows a second drawing-in phase, which follows the first and in which the thread is moved further against the cooling drum 4.
- the texturing nozzle Shortly before the thread is effectively placed on the cooling drum (thread courses F.3 for the rotational direction of the cooling drum being pulled out, and F.5 for the broken direction of the cooling drum in dashed lines) and is braked by the latter, the texturing nozzle must be closed, the conveying medium switched on and with a Accumulation aid, for example the formation of a plug can be initiated in an air stream directed against the nozzle outlet opening.
- a Accumulation aid for example the formation of a plug can be initiated in an air stream directed against the nozzle outlet opening.
- the thread is guided between the plug-conveying roller 2 and the cooling drum 4 and then placed on the cooling drum in accordance with the thread course F.3. It cannot be prevented that the thread is placed further than absolutely necessary around the plug conveyor roller 2 (thread course F.4). So that the thread cannot be damaged by the plug detachment means 3 during this movement, it is advantageous to limit this movement with a corresponding second thread guide 13.
- the thread guide 13 is, like the thread guide 12, advantageously rod-shaped and provided with a groove for the thread.
- the thread guide 13 can also be attached directly below the plug channel 32.
- the thread only has to be moved up to a thread course F.5 and be guided through the guide slot of the pull-in thread guide during this movement.
- the thread guide 5 shown in FIG. 1 extends stationary around the circumference of the needle roller 2 and is spaced from it. It is at least provided between the points 51 (intersection with the thread course F.2) and the plug passage opening 52 with a guide slot or, for several threads, with corresponding guide slots running parallel and with the thread spacing provided, which guide the conveying and grafting channels are aligned.
- the stationary thread guide 5 is described in detail in connection with FIGS. 3 and 4.
- FIGS. 1 a to 1 c how the untextured thread moves clockwise from a thread course F1 via F.2 and possibly F.4 to a thread course F.3 during the pulling-in process with cooling drum rotation and thereby always in the guide slot of the pulling thread guide 5 leads. From such an idea it can also be easily derived that instead of a stationary thread guide 5 with a guide slot, as shown in FIGS. 1 a to 1 c, a thread guide means, which is arranged parallel to the axis of the needle roller and during itself the retraction process essentially moved from the point 51 (FIG. 1 b) to the position of the second thread guide 13, can be used.
- FIG. 1c shows very schematically such a moving thread guide means, the device, which is not shown completely, should be essentially the same as that shown in Figures la to lc.
- the moving thread guide means is a rod-shaped pull-in thread guide 6, which is arranged parallel to the axis of the plug conveyor roller 2 and moves during the pulling-in process from at least one point 51.1, which corresponds to point 51 of FIG. 1b, to a point 13.1 ( Arrow E), position 13.1 essentially corresponding to the position of the second thread guide 13 in FIG. 1c.
- the movable thread guide 6 the design of which is described in connection with FIG. 5, is operatively connected for its movement to a corresponding drive and advantageously a corresponding control (neither of which is shown).
- FIG. 3 and 4 show in more detail a stationary thread guide 5, as has already been shown and described for the exemplary embodiment according to Figures la to lc, which is why the same reference numerals are used.
- Parts of the device for the continuous texturing of thermoplastic threads with the thread guide 5 are shown in FIG. 3 cut along the thread / plug course (section line II-II of FIG. 4).
- FIG. 4 shows the feed thread guide 5 as a top view from the plug feed roller.
- the stationary thread guide 5 has a guide slot 58 which extends at least from the point 51 (intersection with the thread course F.2) to the plug passage opening 52. It also has an inlet area 55, which is on the of the Plug conveyor roller 2 is arranged facing away from the thread run F.2 and in which the guide slot 58 extends to an inlet opening 54. The function of the inlet area is to guide the thread into the guide slot 58.
- the thread guide 5 also has a guide area 56 and a plug passage area 57.
- the guide slot 58 extends over the length of the guide area 56 and widens to an opening 52 in the plug passage area 57.
- a fastening area 59 can adjoin the plug passage area 57.
- thread paths are possible in which the thread runs through the plug passage opening 52 (for example thread path F.4).
- the thread is not precisely guided in this opening.
- the thread guide as shown in the figure, has a bend at point 53 that approaches the needle roller in such a way that the thread in a thread course according to F.4 there in the guide slot 58 is led.
- the thread guide 5 does not have such a bend, but runs essentially in a straight line over the area 53 (shown in dash-dot lines), it is advantageous to avoid a thread course according to F.4, for example by a corresponding position of the second thread guide (13.2, thread course F.6 ).
- the second thread guide has a groove for the thread and thus in turn contributes to guiding the thread transversely to the thread / plug course of the operation.
- Feed thread guides for devices for texturing several parallel threads have a corresponding number of parallel guide slots.
- 5 shows in the same top view as FIG. 4 an exemplary embodiment for a movable thread guide 6, for example for an application according to FIG. 2.
- the movable thread guide could also replace the stationary thread guide in FIG. FIG. 5 is aligned with FIG. 3 in such a way that the movable thread guide 6 assumes the position which it essentially assumes at the beginning of the pulling-in process. It is moved along the arrow E during the pulling-in process.
- the movable thread guide 6 has, for example, a guide pin 60 and an inlet part 61 (analogous to the inlet area 55 of the thread guide 5, FIG. 4).
- the thread course F.2 cuts the thread guide in its initial position at point 51.1.
- a guide pin can also be used, for example, which has a guide groove for the thread running around its circumference.
- the movable thread guide for a device for texturing several threads is correspondingly wider and equipped with several thread guides.
- FIG. 6 now shows parts of a further exemplary embodiment of the device for the continuous texturing of a thermoplastic thread, which differs from the previously described embodiments essentially by the relative arrangement of the needle roller 2 and the cooling drum 4, in particular the plug in FIG essentially horizontally guided by the plug conveyor roller and sucked directly onto the latter without a plug conveying channel through the air sucked radially into the cooling drum for cooling and for holding the plug.
- the figure serves to illustrate that the method according to the invention and the corresponding The device allows various such arrangements, but the thread guide must be adapted or supplemented.
- the adapted stationary thread guide 5.1 guides the thread between a thread course F.2 and a thread course F.7. If the thread is placed further around the plug feed roller, which is only necessary in the case of an arrow drawn in a cooling drum mode, it passes through the plug passage opening 52 and is not guided there. On the other side of the plug passage opening (thread course F.4), a second thread guide 13.3 (for example a rod with guide grooves) can take the lead or the guide slot can continue, so that guidance is again ensured.
- the plug conveyor roller 2 can be equipped with appropriate guide means, as is illustrated by FIG. 7.
- FIG. 7 shows a schematic radial section (section line II, FIG. 6) through a needle roller 2 (only partially shown) with a plug channel delimited by a pair of needle rows 21.
- a guide channel 22 runs in the center of the plug channel on the base of the needle roller and guides the non-textured thread when it is drawn in.
- the figure also shows a detaching wedge 31.
- the needle roller according to FIG. 7 can be used, for example, for the application outlined in FIG. 6 with a cooling roller rotation in accordance with the dashed arrow, which means that thread guidance when pulling in a thread course F is also used for this application. 2 is guaranteed up to a thread course F.4.
- FIG. 8 shows, in the same representation as FIG. 6, a further embodiment of the device according to the invention.
- This embodiment also differs essentially from those already described in the relative arrangement of the device parts.
- the plug sector ie the needle roller sector
- the part of the plug course is very short, such that the course of the plug P takes the form of a perpendicular tangent to the needle roller 2.
- the individual elements essentially correspond to those in FIG. 6 and therefore do not have to be described any longer.
- a thread course F.2 is shown, which corresponds to the tangent from the first thread guide 12 to the rows of needles of the needle roller 2, a thread course F.4, which can correspond to one when pulled in with a cooling drum rotation clockwise (arrow drawn out) and a thread course F.5, which corresponds to counterclockwise cooling direction (dashed arrow).
