Definitions

  • the present invention relates to a plug-on for a spinning machine, in which on each side of a central plane of the machine running in the longitudinal direction of the machine, at least two rows of sliver bobbins rotatably suspended for lateral unwinding of the sliver are lined up side by side and one for Mid-plane parallel row of drafting devices is provided.
  • the vertical position of the deflecting rod is more or less predetermined because it must be avoided that, due to the position of the same being too high or too low, the fuse which is being unwound from the coils is exposed to the risk of damage.
  • the adjustment of the height positioning can therefore only be used to a very limited extent to improve these conditions.
  • This is characterized in that a parallel to this parallel row of rod-shaped holders is arranged, which holders are located behind the front row of coils, are fixedly mounted at one end and have at least two guides for fuses at their other end , which matches run directly from the match spools via the guides to the drafting systems.
  • Fig. 1 shows a front row of coils with the coils 11 and a second row of coils with the coils 12 on which Fibrous webs 13, 14 are wound up.
  • the two rows of coils are located on one side of a central plane 15, which is perpendicular to the plane of the drawing, runs in the longitudinal direction of the machine and halves the attachment in two equal halves. Only one of these halves is therefore drawn.
  • the rows extend parallel to the central plane 15 in both directions than is shown in the figure.
  • the fuselages 13, 14 run from the bobbins 11, 12 via guide elements 16 carried by holders to a drafting arrangement 17 each. Subsequently, threads are spun between the drafting arrangements 17 and rotating spindles (not shown).
  • the sliver coils 11, 12 hang in a known manner on Casablanca pins and are freely rotatable about their longitudinal axes 18.
  • the fuses 13 and 14 are removed from the coils 11 and 12 by rotating the coils about their longitudinal axes 18 perpendicular to the plane of the drawing.
  • the Casablanca cones are carried by coil carrier rails.
  • the latter are not shown in the drawing, since this is a generally known device.
  • the holder 20 shown in FIG. 3 comprises two rod pieces 21, 22, each of which has an end part 23 or 24 provided with a screw thread.
  • a prestressed coil spring 25 is fastened to the end parts 23, 24.
  • the guide element 16 is attached at the lower end of the rod piece 22 .
  • the latter has two guides 27, 28 for fuses.
  • the holders 20 are attached and extended at the uppermost end of the rod piece 21 on the spinning frame, for example on a mounting rail in the example shown down from the mounting point.
  • the fuse 13 is drawn off from each of the coils 11 while rotating them, and is guided via a guide 27 of a guide element 16 to a drafting device 17.
  • the fuse 14 is withdrawn from each spool 12 while rotating it, and is guided via a guide 28 of a guide element 16 to a drafting device 17.
  • a guide element 16 or a holder 20 is located between two adjacent coil groups and between the front row of coils with the coils 11 and arranged second row of coils with the coils 12.
  • the fuse 13 of a coil 11 and the fuse 14 of a coil 12 run over the guides 27 and 28 of a guide element 16 and a holder 20, respectively, the coils 11 and 12 belonging to groups which are adjacent to the holder 20 in question.
  • the coil 11 positioned in front of it (same coil group) must first be removed. Then, by reaching through the alley thus created, the empty coil 12 is cleared of its holder, pulled out through the alley between two front coils 11 and a full coil 12 is again passed through the alley and hung on the holder. It can be seen that this can be carried out more easily than if there were a horizontal sliver deflecting rod which would extend parallel to the central plane 15 at the locations of the guide elements 16.
  • the holders 20 located in the middle between the adjacent coil groups allow the reel to be inserted to move between adjacent holders 20 while these coils are in their vertical position. It is particularly recommended, as shown in FIG.
  • FIG. 3 Such an embodiment is shown in FIG. 3.
  • the holder 20 shown in this figure is provided on the part located between the ends 23, 24 with a flexible member, in this example with a spring 25.
  • the rod 22 can therefore bend the spring 25 be pushed sideways in any direction by hand, so that it can practically no longer be a hindrance when changing the bobbin. Since the spring 25 is pretensioned, the rod piece 22 automatically moves back into its starting or working position after it has been released.
  • FIG. 2 there is a front row of coils 31 wound with a fuse and a second row of coils 32 wound with a fuse; a third row of sliver coils 33 is located in the middle of the machine, ie at the location of the central plane 15.
  • a fuse 34 or 35 runs to a guide element 37 and from this to a drafting device 38
  • a fuse 36 passes from the coils 33 from every second coil to a guide element 37 and a drafting device 38.
  • the other coils 33 do the same Sliver belt is guided onto the left half of the spinning machine according to FIG. On this half, the attachment of the attachment shown is analog.
  • Each second guide element 37 thus has three fuses and two fuses to the intermediate guide elements 37.
  • FIG. 4 An embodiment of a guide element 37 having three guides 41, 42, 43 is shown in FIG. 4. This can belong to a holder which is the same as the holder 20 shown in FIG. 3, with the exception of the guide element 16. Both the guide element 16 and the element 37 ensure a clean separation and, thanks to the U-shaped guides, an easy threading in of the fuses.
  • the guides 41, 42, 43 are distributed at equal angular intervals from one another around the rod piece 32 forming a center.
  • the coils 33 when the coils 33 are replaced, they must be brought through an alley formed by two coils 31, 32 of two coil groups. These streets are therefore longer than those found in the example in FIG. 1.
  • the exchange of the coils thus represents a comparatively laborious process, so that the provision of holders according to the invention is particularly useful here for the exchange of the coils 33.
  • the holders are designed to be evasive and can be moved to the side by hand, there is a very substantial relief for changing the bobbin.
  • the holders or guide elements are located between the second row with the coils 32 and that in the middle of the machine running third row of coils 33.
  • the holder 50 shown in FIG. 5 has two rod pieces 51 and 52.
  • the rod piece 52 carries at its lower end a guide element 55 with guides 53, 54, the shape of which is to a certain extent eyelet-like.
  • the rod section 51 is fixedly connected to a swivel joint 56, while the rod section 52 is pivotally attached to the swivel joint 56.
  • the joint 56 comprises two disks that are prestressed against one another, between which the rod piece 52 is located. Corresponding furrows on the mutually facing sides of the disks define two stable angular positions of the rod pieces 51, 52 with respect to one another. One of these positions is the drawn, stretched arrangement of the rod pieces 51, 52. The other position is given by the rod piece 51 and by the further position of the rod piece 52 indicated by dashed lines.
  • the upper rod piece 51 is fastened to a machine part.
  • the lower rod piece 52 is folded aside before the replacement of a spool in the position shown in broken lines, so that the required alley is completely free during the replacement. After the replacement, the rod piece 52 is folded back into its vertical position forming the working position.
  • the height of the threads of the end parts 23, 24 and the height of the spring 25 are the same.
  • the parts 23, 24 can be screwed to the spring 25. Once they are screwed together, they are very tight, because when they are rotated in the sense of loosening this screw connection, the spring is in the circumferential direction, i.e. tightened in the direction of its turns so that it jams. It is therefore self-locking. There are therefore no additional measures such as Additional screws for mutually fastening the parts 23, 24, 25 are necessary.
  • a steel spring is a very durable, elastic member. Because of the unavoidable flight of fibers in textile processes, it is advisable to cover the spring with a soft protective jacket 29. The same naturally also applies to the swivel joint 56 shown in FIG. 5.
  • the coupling of the rod pieces 21, 22, elastic member can also consist of rubber, which is slipped over the end parts 23, 24 in the case of a hose-like configuration or is fixed as a solid cylinder in bores present in the end parts 23, 24.
  • the broken line position of the rod section 52 forms an obtuse angle with the rod section 51.
  • a right angle can be provided for the notched position.
  • the number of guides available on a holder can be selected as required, depending on the requirements.
  • the holders 20, 50 were fastened to a carrier rail provided for this purpose.
  • the holders are fastened to a coil carrier rail, the fixed rod piece being angled, or if the holder is designed in a straight line, the holder is positioned obliquely in its working position.
