Definitions

  • the invention relates to a shaft device according to the preamble of claim 1.
  • Shaft devices of the type mentioned are in many Form known, for example from CH-PS 523 987, which are also explained in more detail in the accompanying FIGS. 1 to 4 is.
  • the known shaft devices require one relatively large play between a drive mounting rail and the end loop of a strand, around one for handling the strand to ensure sufficient spread angle.
  • This big one Game causes wear on the one hand and on the other hand strong noise.
  • such shaft devices or weaving machine speeds equipped with it allowed of a maximum of 2500 revolutions per minute.
  • a shaft device is the beginning known type, in which the end loops a lateral Have an opening for attaching to a mounting rail.
  • the mounting rail has one from the side of the level of the mounting rail projecting leg on the in a driving groove of associated end loop engages.
  • the game is Leg very large in the driving groove of the mounting rail, see above that actually no longer speaks of a driving groove can only be from an edge on which the leg the other side of the driving groove has no function can unfold, but the end loop by other means, for example, a suitable bias on the edge must be kept.
  • This shaft device allows also no high drive speeds of the weaving machine.
  • the object of the invention is to provide a shaft device to improve the type mentioned at the outset in such a way that Disadvantages are avoided.
  • the service life of the shaft device can be determined by a Improve training according to claim 2, since then the driving force is distributed on two legs. This diminishes at the same time the wear and the increasing Wear increasing noise level.
  • leg of the drive mounting rail it is possible to use the leg of the drive mounting rail to be arranged at any height of the drive mounting rail, however, training according to claim 3 is advantageous is.
  • the design enables the cheapest power distribution according to claim 4.
  • An embodiment of the mounting rails is particularly advantageous in particular the drive support rail according to claim 5, because this profiling enables the training of the Leg and on the other hand ensures a good bending moment at low mass compared to a full profile the mounting rail.
  • the lower mass of the mounting rails favors higher operating speeds and contributes to Reduction of noise and wear.
  • Claim 6 includes an advantageous width of the driving groove.
  • Claim 7 quantifies a preferably vertical Game between the end loop and the non-driven DIN rail to a required spread angle for the Ensure handling of the strands.
  • the stranded wire can be of any design, however, the training according to claim 8 of particular
  • the advantage is that it enables the least amount of sideways movement Good strength and wear properties required.
  • An embodiment according to claim 9 is particularly advantageous, usually two mounting holes are available. This enables a further development according to claim 10.
  • the assembly device makes it easier to set up strands beforehand with warp threads. Then by means of the mounting device Wires are pushed on and off the mounting rails, whereby the set-up and changeover times for example at one Change of the articles to be manufactured significantly reduced become.
  • FIGS 1 to 4 describe a shaft device, such as for example, it is the subject of CH-PS 523 987.
  • the Shank device has a vertical profile bar 1 an upper drive support rail 2 and a lower guide support rail 3 each secured by means of jaws 4 are.
  • On the drive support rail 2 and the guide support rail 3 strands 5 are lined up by means of end loops 6, 7.
  • the Strands 5 carry thread eyelets 8 through which one warp thread each 9 is performed.
  • the profile bar 1 contains one Tab 10 with pin 11 on which a two-armed drive lever 12 attacks.
  • the drive lever 12 is on an axis 13 pivotally mounted and carries on the facing away from the profile bar End a roller 14 that is powered Eccentric 15 works together.
  • a biasing spring 16 biases the by the support rails 2, 3 formed frame below in front and thus also the role 14 against the Eccentric 15.
  • the end eyelet 6 is the Strand 5 with a considerable play of, for example, 0.5 arranged up to 1 mm on the drive support rail 2, the an upright flat profile is formed. This Play is required to spread the strand on both sides the vertical 17 to allow, for example To be able to carry out thread repairs.
  • the spreading angle a is preferably 15 ° to the vertical 17th
  • FIGS. 5 and 6 show a further development according to the invention the shaft device, the one with the known Shaft device identical parts with the same reference numerals are provided.
  • 5 shows two strands 5a, the two shafts are assigned and the warp threads 9 too open a warp pocket 18 into which a weft thread 19 is inserted and by means of a reed 20 on a product edge 21 can be posted.
  • the upper drive support rail 2a has a C-shaped profile, the lower leg 22 is parallel to the warp thread level 23 and in a driving groove 24 engages that on the inside of the end loop 6a of the strand 5a is formed.
  • the leg 22 is made very thin and has, for example, a thickness of 0.8 mm.
  • the width of the driving groove 24 is correspondingly small and is at most 1.0 mm.
  • the thickness of the leg 22 and the width the driving groove 24 are coordinated so that the Game between the leg 22 and the driving groove 24 0.01 to 0.1, preferably 0.05 mm.
  • the lower guide rail 3a can be analogous to the upper drive support rail 2a be designed, with a vertical play of 0.5 to 10 mm is possible.
  • the guide support rail 3a is not used for Drive the strand 5a, but to guide the strand in the shaft and absorption of those caused by the moving warp threads Lateral forces.
  • the strand 5a also contains assembly openings 25 for Facilitation of the assembly of the strand 5a on the mounting rails 2a 3a, as described in more detail below with reference to FIGS. 9 and 10 becomes.
  • FIG. 7 shows an L-shaped cross section Drive support rail 2b, which interacts with a strand 5b, which has a correspondingly shaped end loop 6b.
  • the leg 22a engages in a corresponding driving groove 24a the end eyelet 6b, which is predetermined by the L-shape.
  • FIG. 8 describes a further drive support rail 2c, the two legs 22b pointing in opposite directions and 22c formed by cuts 26 in a full profile are formed.
  • the opening of the end eyelet 6c is analogous designs and in turn has driving grooves 24b, 24c, in which engage the legs 22b and 22c.
  • Figures 9 and 10 show a mounting device 27 of the Shaft device.
  • This consists of at least one end bar 28 or 29, which has openings 30, 31 on the drive support rail 2a and the guide support rail 3a can be pushed on is.
  • the two end rods in the present example 28, 29 are connected to one another by two assembly rods 32, 33, these assembly rods not shown in detail Threads included that provide a detachable connection to the end bar 29 enable.
  • the mounting device 27 serves to regardless of the arrangement on the drive support rail 2a and the guide support rail 3a to accommodate strands 5a. For this the end rod 29 is released from the assembly rods 32, 33, so that the strands 5a by means of the mounting openings 25 on the Assembly rods 32,33 can be pushed on.
  • the assembly device 27 can be removed again by removing the end rod 29 from the assembly rods 32, 33 loosened and the assembly rods 32,33 pulled out of the strands become.
  • the end rod 29 can be open due to the side Openings 30, 31 from the drive support rail 2a and the guide support rail 3a be posted.
