Definitions

  • the technical field of the invention is textile machines.
  • a route is particularly affected which has a calender device, which usually consists of two opposing calender rolls or calender disks, with which the sliver is compacted.
  • the sliver guide and the guide nozzles which fix this guide are affected by the invention.
  • a pair of delivery rollers to be arranged at the exit of a drafting system of a draw frame (as an example of a sliver processing machine), which conveys nonwoven into a fleece funnel.
  • the fiber sliver is spread out in accordance with the roller width due to the distortion.
  • the person skilled in the art describes the fiber sliver that is spread out at this point as a non-woven fabric.
  • the non-woven fabric ie the spread fiber sliver is conveyed into the opening of a non-woven funnel.
  • the fleece funnel the fiber fleece is rolled up and combined and transported further through the funnel mouth to a sliver tube which has a considerable length.
  • the sliver is introduced into a sliver funnel, which deflects the conveying direction of the sliver by approximately 90 ° and introduces it between a pair of calender rolls. After passing through the pair of calenders, the sliver compacted there is conveyed on to the laying device of the draw frame.
  • a sliver funnel which deflects the conveying direction of the sliver by approximately 90 ° and introduces it between a pair of calender rolls.
  • the sliver compacted there is conveyed on to the laying device of the draw frame.
  • the sliver tube being designated 8 and the delivery rollers of the draw frame 70b and 70a.
  • a structure with a long sliver tube 8 is also described in EP 593 884 A1.
  • Another example of a long sliver tube (also designated 8 there) is US 4,372,010; the pair of calender rolls is designated 9a, 9b there.
  • Another example of the custom of the long sliver tube is shown in DE-A 26 23 400 .
  • the sliver tube itself is curved at an angle of approximately 90 ° and guides the sliver without changing the angle between the calender disks designated 5, 6 there. It is described as advantageous if the tube denoted by 14 is flattened in an oval shape (see page 9, last paragraph).
  • the DD 290 697 also shows a collecting tube. There, the fleece funnel and belt funnel are clearly spaced apart.
  • a ventilation opening (there 8) allows the air flowing in at the beginning of the collecting pipe (there 5) to escape completely in front of the narrowest point of the band funnel.
  • DE-PS 36 12 133 relates to a belt guide channel between output rolls and calender rolls on a spinning preparation machine.
  • the tape guide channel concerns the automatic insertion of a tape start into a tape funnel (column 1, 9th - 10th row).
  • the ribbon guide channel is relatively long and gives the fiber ribbon the necessary guidance on the way to the ribbon funnel. In this way, several injectors (air duct, compressed air line) are arranged. The entire tape mass is drawn in the tape guide channel using an injector. The tape mass at the beginning of the tape must then only be compressed in the tape funnel (there column 1, 54th - 58th row). There is a problem of air congestion in the belt funnel (column 1, lines 59 to 62).
  • the band hopper must have a device for temporarily increasing its cross section. This is a prerequisite for automatic insertion of the sliver.
  • Another disadvantage is that the calender rollers must also be opened to automatically insert the beginning of the tape. The beginning of the belt cannot be drawn into the nip of the calender rolls when the closed calender rolls rotate.
  • the invention is based on the task of reducing the downtime of textile machines caused by fleece jam.
  • the arrangement of the pivoting axis makes it possible for the back pressure of the supplied nonwoven to automatically pivot out of its operational position when it can no longer be conveyed away, in order to pivot a ramp section of this nozzle into the operational conveying channel, which has such an inclination in the pivoted-in position that the fleece which strikes it (initially further conveyed) is deflected out of the interior of the drafting device transversely to the normal transport direction (claim 10, 11).
  • the arrangement of the pivot axis results in a very small lever arm, on which the fleece conveyed into the fleece funnel engages in order to require only slight forces to pivot the fleece funnel.
  • the fleece funnel folds out particularly easily in the event of a fleece jam if the pivot axis lies below the fleece funnel (claim 22) and the axis kink K lies in the pivot axis (claim 9).
  • the fleece funnel can be designed to be removable in all of its operational positions, but in particular in the pivoting position, which corresponds to both the processing position for threading the fleece and the fleece stowage position (claim 14).
  • the processing position or fleece stowage position can be buffered (claim 12, 13) in order to achieve a gentle stop with automatic pivoting.
  • the buffered pivotability can also be used manually to carry out maintenance or cleaning work.
  • the pivotable nozzle (fleece funnel) has a funnel area (claim 16) and an adjacent ramp or plateau area, so that the nonwoven fabric is formed in the operating position of this nozzle by rolling, deflecting and merging into fiber sliver and ensures the ramp area when the nozzle is tilted that the non-woven fabric conveyed towards it is deflected in such a way that it is conveyed out of the deflection area, the drafting area is not blocked and can be easily removed by the operator (claim 20).
  • the ramp area also ensures that no fleece jam can form because the nozzle then automatically swivels due to the force of the fiber fleece conveyed on it and the ramp area guides the fiber fleece that is still being conveyed away from the drafting system interior until the delivery rollers are switched off.
  • This nozzle has immediately assumed its working position, which corresponds to the position it assumes when fleece jam occurs (claim 14).
  • the pivotable, rectangular nozzle (claim 17) can be pivotally mounted in the belt funnel nozzle (a cylindrical funnel-shaped nozzle). However, the pivotable nozzle can also be pivoted together with a nozzle section which is designed as a band funnel and adjoins it directly on said calender guide section (cf. FIG. 9a, FIG. 8a).
  • the compact structure begins directly behind the last delivery roller with a clear path change (claim 6) even before entering a guide channel.
  • the additional deflection roller whose axis is slightly above the normal fiber run, can provide more than 50 ° deflection without impairing the fiber stretch quality (without deflection roller) and lies approximately in one plane with the pivot axis V and the calender gap.
  • the ramp level of the fleece funnel is determined according to claim 18, depending on the stop angles ⁇ 1, ⁇ 2 or ⁇ A, ⁇ B.
  • the fleece funnel is clearly spaced from the band funnel by spacing bearing plates (claim 19) relative to the total length of the sliver guide and yet is attached close to it.
  • the overlay in FIG. 1 illustrates the difference from the prior art, which is shown schematically in FIG.
  • the fiber sliver FV which has not yet been stretched when it is introduced into the drafting system is introduced in the prior art via stretching rollers 67a, 68b, 69a, 69b and delivery rollers 70a, 70b into a fleece funnel and from there into a long guide tube 8 which opens into a band funnel 9.
  • the sliver funnel deflects the fiber sliver FB about 90 ° into the nip of the calender with its calender discs 100a, 100b.
  • calender discs or a pair of calender discs This term also includes the pair of calender rolls.
  • the calendered fiber sliver KF emerges vertically downward from the calender and arrives at a depositing device and is deposited from there (by means of a turntable, not shown) in a can.
  • This sliver guide is also shown in FIG. 2 with the same reference numerals.
  • An embodiment of the invention shortens the sliver path and eliminates the sliver tube 8.
  • An additional deflecting roller 71 is added, which causes a deflection of approximately 60 ° in the nonwoven conveying direction FV and introduces the nonwoven fabric into a sliver channel, consisting of several functional elements.
  • the first element is the fleece funnel 50 with a ramp surface 50b and a funnel section 50a arranged directly thereon, in which the broadly arriving fiber fleece is folded, folded over and introduced into a first channel section.
  • the channel section is formed by an insert 40, which is inserted on the rear side of the funnel section 50a of the fleece funnel 50 and fastened with a screw. It can be adjusted.
  • the fleece funnel 50 (with an inner insert) can be tilted such that the ramp surface 50b can be pivoted into the fiber band guide and the funnel section 50a next to it.
  • an articulated surface 41a, 41b is provided, which in the angular position ⁇ B , which is shown in FIG. 1 or FIG. 2b , enables the guide channel to be sealed off from the subsequent band funnel 30.
  • the articulated surface 41a, 41b of the front, cylindrical section of the inner insert 40 which is symmetrical to the center plane of the first insert 40, consists of two continuously curved surface sections 41a and 41b which narrow towards the rear (in the axial direction) and which engage in a corresponding bearing surface 35 on the belt funnel 30.
  • 4a and 4b show this joint surface in two views at the front end of the insert 40 for the fleece funnel 50. Swiveling the fleece funnel 50 in the direction ⁇ into the other angular position ⁇ A does not release the radially airtight seal between the fleece funnel and the band funnel. Radially airtight sliver guidance is achieved both in the swung-in ( ⁇ B ) and in the swung-out ( ⁇ A ) state.
  • the fleece funnel 50 is temporarily designed - with an insert 40 which can be inserted counter to the fiber conveying direction - the above-mentioned relative adjustment can be carried out on a handle 51.
  • the fiber sliver is conveyed through the fleece nozzle 50, the inner insert 40 and the belt funnel 30 into the guide channel up to the clamping gap 100c, for which purpose the fleece funnel 50 is swung out.
  • the fleece funnel 50 is swung out.
  • the section F1 of nonwoven fabric which is narrowed by hand according to FIG. 3 and held in the funnel mouth 50a is sucked in.
  • a short suction flow in the cylindrical channel 31 of the order of 500 ms is sufficient.
  • a short angular momentum of duration T 2 is applied to the calender disks. It can switch itself on after a predetermined suction time T 1 , can be superimposed on it or can be initiated separately manually.
  • FIGS. 5a, 5b and 5c The shape of the band funnel 30 can be seen more clearly in FIGS. 5a, 5b and 5c , where the direction and arrangement of the injector bores 34a, 34b in the band funnel are also shown enlarged. They open into a cylindrical channel 31, which forms the front end of the sliver channel.
  • the cylindrical section 31 widens via a conical section 32a to the diameter of the channel 32, which is predetermined by the inner insert 40.
  • the bearing surface 35 is provided, which corresponds to the articulation surface 41a, 41b in its curvature.
  • the two inclined injector bores 34a, 34b can run at an angle of approximately 45 ° with respect to the axis 200b of the band funnel insert 30.
  • they can open in a common plane in the cylindrical section 31, offset in parallel, in addition to the injector effect to give the inserted sliver a twist and additional strength. This arrangement is shown in FIG . 5d .
  • the injector bores begin above a cylindrical section 33 of the insert 30 in an annular channel 36 open to the outside.
  • a band funnel holder 60 according to FIGS. 6a, 6b, 6c has in the upper approximately cylindrical section 67 a central, approximately cylindrical opening 62 into which the band funnel insert 30 is inserted.
  • an annular channel 63 which can be fed with compressed air from two or more cylindrical bores 64a, 64b, extends inwardly in the cylindrical opening.
  • the compressed air introduced from the outside is introduced into the inclined injector bores 34a, 34b when the ribbon funnel insert 30 is inserted, in order to open into the cylindrical section 31 of the fiber ribbon channel, which is close to the clamping gap 100c.
  • the interchangeability of the inserts 30, 40 enables a quick changeover to changed channel widths as a result of different sliver material when the batch is changed.
  • FIGS. 6a and 6b illustrate the cylindrical beak 61 of the band funnel holder 60, which adjoins a conical section 68 which forms the transition between the upper, cylindrical end 67 and the beak 61. It has a length L and a diameter, shown in the cross section of FIG. 6b as width b.
  • the beak 61 is arranged in a fixed manner and has two halves, since - as can be seen in FIG. 6c - it is slit on the side. According to the schematic illustration in FIG. 7 , a segment of the rotating calender disks 100a, 100b engages in the two slots mentioned. This can also be clearly seen in FIG. 1 in the right half. In the middle of the beak of the band funnel holder 60 - i.e.
  • FIGS. 7a and 7b can both be closed (clamping gap 100c) and also opened by putting away the calender disc 100b can be opened (open clamping gap 100d).
  • the integrally molded beak halves 61a, 61b which are formed by the aforementioned slots 61c, 61d in the cylindrical beak 61, guide the guide air.
  • the guide air was previously introduced into the annular duct 63 via the injector bores 64a, 64b and from there via the injector bores 34a, 34b of the band funnel 30, which run obliquely to the axis 200b, into the fiber band duct. With the beaks it is avoided that the guide air escapes in front of the gap 100c, 100d, rather it is guided beyond the gap to behind the clamping gap.
  • a first narrow channel section 65a on one side of the calender disks or a second narrow channel section 65b on the other side of the calender disks, which have an approximately semicircular cross-sectional shape, serves to guide this air.
  • the respective channel is very narrow compared to the thickness d or width b of the beak 61 or its inner wall, which is directly adjacent to the side surface of the calender disk.
  • the width b of the beak and the overlap d of the inside of the beak halves with respect to the calender disc a sealing effect, which is formed without contact by significant to considerable lateral flow resistance to the axial side air channels 65a, 65b.
  • the air not only passed the calender gap, but also clearly passed through the calender gap.
  • the sliver is also immediately threaded through the calender nip and the calender disk 100b can then be closed (closed position) in order to have reached the operating position with the sliver threaded.
  • the sealing surface part of the cover d
  • the sealing surface is large enough in relation to the air resistance of the now enlarged passage channel, consisting of the channel segments 65a, 65b and the opened calendering gap 100d, in order to prevent radial escape of guide air .
  • FIGS. 8a and 8b show an embodiment of a guide section which is essentially made in one piece and contains both the fleece nozzle 50 and the belt funnel 30.
  • the band funnel 30 is inserted directly into the fleece nozzle 50 and is additionally fixed in position by a tube holder 80.
  • the front end of the band funnel 30 is supported in comparable bearing shells and rounded surfaces, as described for the fleece funnel insert 40 with reference to FIGS. 4b and 5c .
  • FIGS. 8a and 8b The radial seal is also achieved in FIGS. 8a and 8b , where a residual guide section 61 'is fixedly arranged with respect to the calender disks, for example on the holder 20 according to FIG. 9a.
  • the remaining guide section 61 ' corresponds to the beak region L of the band funnel holder 60 from FIG. 6a.
  • the air is introduced into the combined fleece funnel / belt funnel at the front end thereof via inclined injector bores 34a, 34b, with a pivoting movement causing a slight pivoting of the air introduction region, which, however, is only slight due to its proximity to the pivot point K.
  • FIGS. 8a and 8b are designated ⁇ 1 and ⁇ 2 , they correspond to the pivot positions ⁇ A and ⁇ B , but can be dimensioned slightly differently, since the pivotable part in FIGS. 8a and 8b is larger or longer than in Figures 3a and 3b .
  • the sliver guide sections are defined by different bores and corresponding conical transition sections.
  • An exchange of the insert 40 is at the same time an exchange of the band funnel 30. Readjustment or adjustment work can be omitted due to the one-piece design.
  • the annular holder 80 does not lie completely flush with the combined fleece funnel / belt funnel, but rather leaves an annular space 81 between the inside of the funnel and the outer diameter of the largely cylindrical combination funnel 30/40.
  • the annular space 81 guides the compressed air used to guide the fibers, whereby it is sealed at the end by flush (annular) contact with the combination nozzle - below the injector bores 34a, 34b.
  • the injector bores are clearly inclined with respect to the axis 200a, they open out just before the radially airtight joint at the kink K, at which radial airtight mounting takes place in both positions of FIG. 8 and FIG. 8b .
  • angles ⁇ 1 and ⁇ 2 are slightly in each case reduced with respect to the example of Figures 2a and 2b, but in the same specified range, as shown in Figures 2.
  • the exact angle is in this embodiment for ⁇ 2 is about 5 ° for ⁇ 1 is approximately 25 ° ( ⁇ 10%), while in Figure 2a an angle ⁇ A of approximately 30 ° and in Figure 2b an angle of approximately 7 ° ( ⁇ 10%) worked reliably in the experiment.
  • the plateau region 50b in FIGS. 8a and 8b is accordingly somewhat adapted to the angle of the ramp region 50b in FIGS. 2a and 2b. It depends on the angles ⁇ in the respective swivel end positions; wherein the swivel position ⁇ 1 and ⁇ A specifies such an angle of the ramp that the direction of conveyance of the nonwoven fabric FV is clearly directed transversely from the exit region of the route. It is most advantageous if the transverse direction of FV has a slight component downwards, that is, it is inclined slightly downwards relative to the horizontal.
  • the ramp area either has a slight slope of 1 ° to 2 ° with respect to the funnel area or it is slightly conical.
  • FIGS. 8a and 8b two different guide channel dimensions are shown in FIGS. 8a and 8b , a narrow and a wide one, each with a conical shoulder to the narrowest cylindrical channel section.
  • FIGS Figures 4 and 5 show a side view and a top view of the fleece funnel 50 with its ramp area 50b and its funnel area 50a according to FIG. 3.
  • the pivoting axis V is transverse to the guide axis 200a, 200b and runs through the airtight joint 41a, 41b and 35, as in FIGS Figures 4 and 5 explained.
  • the pivot axis V runs through the bearings 50c which are formed are by lateral holding tabs 52a, 52b and pin, on which at least half open pivot receptacles can be placed on the front.
  • the fleece funnel 50 can thus be removed and tilted, while at the same time sealing the internally formed guide channel 200a, 200b in an airtight manner.
  • FIGS. 9a and 9b show the pivotable fleece nozzle 50 with ramp section 50b and funnel area 50a.
  • the pivot axis V is shown and is defined by a joint which is shown schematically to the right of FIG. 9b.
  • a bearing tab 52a (on the opposite side 52b) has an approximately semicircular recess which is open at the bottom and is placed on a pin 50c to form a joint. Because of the smooth transitions at the opening end of the exception 53a (at the opposite end 53b), the fleece funnel 50 can be easily removed and replaced. The direction of the arrow F indicates this.
  • the fleece funnel 50 can be pivoted through the angle ⁇ , which pivoting is either generated by a user on the handle 51 or is caused by a fleece backlog and the resulting dynamic pressure above the pivoting axis V, the ramp region 50b being pivoted in the conveying direction of FV.
  • the width of the ramp area 50b is e and is approximately as wide as the inlet area of the funnel section 50a. It can be slightly conical and it can be inclined at an angle ⁇ 1 with respect to a plane E 1 which is perpendicular to the axis 200a of the sliver channel (cf. FIG. 3b).
  • the inclination ⁇ 1 is matched to the swivel angle ⁇ A , which is the end position (processing position) when the fleece funnel is unfolded.
  • the fleece conveying direction FV ' should lead out of the drafting system area at approximately 90 °. Accordingly, an angle of approximately 30 ° (20 ° to 40 °) will be selected in practical use.
  • the inlet area of the funnel section 50a has a somewhat reduced angle ⁇ 2 with respect to the plane ⁇ 1 .
  • the difference between these two angles ⁇ is between 1 ° and 5 °.
  • an improved, i.e. constant rolling of the fleece is achieved when inserting the tape into the guide section.
  • the machine is secured against downtimes in such a way that the fleece funnel swings out itself and directs the further sliver run into the exterior of the machine, where the sliver which is no longer properly stretched can be easily removed.
  • the operating times are shortened and simplified.
  • the ramp 50b of the fleece funnel enables the processing position in addition to the stowage position, without a user first having to pull out sliver from the drafting system area. The latter happens automatically.
  • the fleece nozzle ramp 50b closes the possible space for uncontrolled fiber fleece transport and thus the formation of wraps.
  • the machine can be monitored electrically.
