Definitions

  • the invention relates to a guide device for projectiles for weft insertion in a rapier projectile weaving machine with a device for braking the projectiles at the end of the guide device.
  • guide teeth forming a weft channel are used on the sley, which are arranged as exactly as possible in alignment between the acceleration device and the braking device for the projectile.
  • the guiding teeth are also aligned precisely with the exit channel of the accelerating device and the entry channel into the braking device.
  • a guide device for projectiles is described, for example, in German Patent No. 26 28 625.
  • the projectiles are guided with a play of a few 1/10 mm.
  • the braking device of a projectile weaving machine has a fixed and a movable brake shoe. Both shoes are each provided with a brake pad made of plastic, which after a longer time Operating time is so worn out that an exchange for a new surface is necessary. Due to the progressive wear on the brake pads, the brake channel formed by the pads gradually shifts downward relative to the firing channel, so that at the end of the flight a projectile has to overcome a step at the transition from the guiding device into the braking device. In this transition phase, undesirable transverse forces occur between the projectile, the guide device and the braking device, which can lead to malfunctions. It is the object of the invention to achieve an improvement particularly in this regard.
  • a second guide section follows a first guide section with tight vertical play for the projectile, which gives the projectile a considerably greater play in the direction of the normal forces (N, N ') acting on the projectile in the brake than in the first guide section, the second guide section extending over a short distance in comparison to the total length of the guide device in front of the entry opening for the projectile into the brake device 6.
  • Fig. 1 is a projectile after passing known guide teeth just in the area of the guide device 4 according to the invention between the front guide support 4a and the rear guide supports 4b shown immediately before entering the braking device 6.
  • the projectile between the upper movable brake pad and the lower fixed brake pad is decelerated to a standstill by the normal forces (N, N ').
  • the space between the two brake pads is referred to as brake channel 9.
  • the front and rear guide support 4a, b can be integrated in a guide element or can also be designed individually, wherein they are fastened in the guide tooth holder 3 in one plane or in different planes perpendicular to the direction of flight of the projectile.
  • the guide tooth holder 3 is preferably designed as a plastic block.
  • the guide supports 4a and 4b guide the projectile 1 on the vertical side surfaces F1 and F2. If the brake pads 7 and 8 in the brake device are not yet worn, the projectile 1 is in the position in the brake channel 9 shown in solid lines in FIG. 2. 2 marked dimensions r down. The projectile 1 is then in the brake channel with its lower horizontal surface at the level of the line la according to FIG. 2.
  • FIG. 3 shows a further guide device 4 'according to the invention analogous to FIG. 2.
  • the figures do not show the playing relationships between the guide and the projectile to scale.
  • the distances between the surfaces Fl and F2 or Fl 'and F2' to one another are selected such that the projectile can move back and forth by a few 1/10 mm in the horizontal direction as well as in the guide teeth 2.
  • the distances between the boundary surfaces F3 ', F4' and F5 ' are selected such that the projectile has a range of motion of greater than 1 mm in the direction of the normal forces in the braking device.
  • the upper part of the guide teeth 2 must be designed such that the edge 2a of the guide tooth according to FIGS. 2 and 3 does not protrude to the left beyond the vertical line imagined by the surfaces F2 or F2 ', so that the weft thread 5 when the guide teeth are compressed 2 and the leader direction 4 can emerge from the shed formed by the warp threads 0 and U according to FIG. 1 without touching the guide tooth 2 or the guide device 4.
  • FIGS. 4 and 5 a plan view and a side view of the arrangement according to FIG. 1 are shown in FIGS. 4 and 5. Due to the wear between the brake pads 7 and 8 and ongoing readjustments on the upper movable brake part (not shown) with the pad 7, the projectile may be displaced by a maximum of dimension r. Since the brake pads 7 and 8 essentially only guide the projectile from above and below, good lateral guidance by the guide supports 4a and 4b is important during the entry of the projectile into the brake 6.
