Definitions

  • the present invention relates to a plug-on device for a spinning machine, in which in the longitudinal direction of the machine at least two rows of sliver bobbins which are rotatably suspended for the lateral unwinding of the sliver and are arranged parallel to one another are lined up in the longitudinal direction of the machine, a parallel row of drafting devices is provided and one to the latter parallel row of rod-shaped holders, the axes of which run parallel to the coil axes, is arranged, which holders are located behind the front row of coils and are fixedly mounted at one end and have a guide for the fuses at their other end.
  • the vertical position of the deflecting rod is more or less predetermined, because it must be avoided that due to its position being too high or too low, the fuse which unwinds 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.
  • a plug-in for a spinning machine according to the preamble of the present invention is known, in which there is a parallel row of rod-shaped holders behind the front row of coils, the holders being fixedly mounted at one end and on have a guide for the fuses at the other end.
  • the rows of sliver coils are arranged on both sides of the central plane of the machine running in the longitudinal direction of the machine, that a row of holders is provided on each side of the central plane, that a holder is assigned to at least two successive sliver coils and that each holder has at least two guides for the slits running from the sliver coils lying one behind the other, which slats run directly from the sliver coils via the guides to the drafting units.
  • Fig. 1 shows a front row of bobbins with the bobbins 11 and a second row of bobbins with the bobbins 12, on which fiber lunches 13, 14 are wound.
  • 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 median plane 15 further in both directions than that 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. The spinning of threads then takes place 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 pins in turn 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 preloaded coil spring 25 is fastened to the end parts 23, 24.
  • the guide element 16 is attached.
  • the latter has two guides 27, 28 for fuses.
  • the holders 20 are on the top end of the rod piece 21 in Fig. 3 on the spinning frame, e.g. attached to a mounting rail and extend downward from the attachment point in the example shown.
  • 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.
  • the coils 11, 12 lying one behind the other in the direction perpendicular to the central plane 15 are considered to be a coil group, there is a guide element 16 or a holder 20 between two adjacent coil groups and between the front row of coils with the coils 11 and the second Coil row arranged 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 released from 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 end parts 23, 24 with a flexible member, in this example with a spring 25.
  • the rod 22 can be pushed sideways in any direction by bending the spring 25, so that it can practically no longer be a hindrance when changing the coil. Since the spring 25 is biased, the rod piece 22 automatically moves back into its initial or working position after it has been released.
  • the sliver 13, 14 can be pulled in more easily through the guides 27, 28 than if the sliver has to be placed around a sliver deflecting rod when it is located at the center plane 15.
  • a particularly effortless threading is obtained with guides which, as shown in Fig. 3, are U-shaped. It should be taken into account that the coils are at a noticeable height and that the coil space can be deep to the rear.
  • the guides 27, 28 shown in comparison with a deflection around a rod guiding the fuses cleanly because the latter are forcibly kept apart.
  • a fuse 34 or 35 runs to a guide element 37 and from there a drawing frame 38.
  • a fuse 36 passes from every second coil to a guide element 37 and a drawing frame 38.
  • the sliver belt is guided to the left half of the spinning machine according to FIG. On this half, the insertion 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 the third row of the coils 33 running in the middle of the machine.
  • 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 relative to one another. One of these positions is the drawn, stretched arrangement of the bar pieces 51, 52. The other position is given by the bar piece 51 and by the further position of the bar 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 coil in the position shown in broken lines, so that it completely clears the required alley during the replacement. After the replacement, the rod piece 52 is folded back into its vertical position forming the working position.
  • 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 the end parts 23, 24 provided bores.
  • 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 chosen according to the requirements.
  • the holders 20, 50 were fastened to a carrier rail provided for this purpose. But there are also Embodiments according to the invention are possible in which the holders are fastened to a coil carrier rail, the fastened rod piece being angled, or if the holder is designed in a straight line, the holder is positioned obliquely in its working position.
