Definitions

  • the present invention relates to a clamping device for a flat thread layer, with a fixed clamping rail and with a clamping member which is adjustable relative to the latter.
  • Clamping devices of this type are used, for example, in warp thread drawing machines and in ebette knotting machines for clamping the warp threads. They generally consist of a clamping bar extending over the entire width of the chain and of a rod-shaped clamping comb held in or on the clamping bar, which is pressed into the clamping bar from above and then locked with it. In the disassembly process after the tying operation, the clamping rail or the clamping comb must be pulled out laterally after the clamping has been released.
  • this clamping device is to be used on the weaving machine when changing the warp, then the lateral removal of the clamping comb and / or the clamping rail is very cumbersome for reasons of space alone.
  • the clamping rail would also have to be provided in a suitable manner at the clamping point, for which purpose either a lateral insertion before the clamping or a permanent arrangement on the weaving machine would be required.
  • the former has the disadvantages already mentioned for the clamping comb and the permanent arrangement on the weaving machine would lead to intolerable contamination and dusting of the clamping rail.
  • the constant arrangement of the clamping rail on the weaving machine would not incur considerable additional costs.
  • the invention is now intended to provide a clamping device of the type mentioned at the beginning, the handling of which is considerably easier and also more automation-friendly than in the known devices mentioned.
  • the clamping member consists of a plurality of clamping elements arranged next to one another, which one between an immersion position and a clamping position in or for the Thread layer pivotally adjustable bow or wing-like clamping part.
  • the invention thus proposes a one-sided clamping device, so to speak, that is one in which only one side of the thread layer has to be accessible.
  • This one-sided clamping device contains, on the one hand, a fixed clamping rail and, on the other hand, clamping elements mounted thereon, which are adjustable between two pivot positions.
  • the clamping elements can dip into the thread layer from one side. If they are pivoted into the clamping position after passing through the thread layer, then they grip around the thread layer from the other side and, together with the clamping rail, form a clamping gap which is closed when the clamping elements move back to the clamping rail.
  • the invention further relates to the use of said clamping device for clamping a warp thread layer.
  • This use is characterized by the following measures: a. Positioning of the clamping device on one side, above or below the thread layer; b. Movement of the clamping device with the clamping elements of the clamping member in the immersion position against the thread layer until the clamping elements pass through it; c. Adjustment of the clamping elements in their clamping position and * return movement against the clamping rail to close the clamping gap formed between the clamping elements and the clamping rail and comprising the thread layer on both sides.
  • FIG. 1 shows a detail from a clamping device according to the invention for a warp thread layer, seen in the direction of the warp threads
  • FIG. 2 shows a section along the line II-II of FIG. 1
  • FIG. 3 shows a detail in the direction of arrow III of FIG. 1.
  • FIG. 1 and 2 show a front and a side view of a clamping device according to the invention, which according to the illustration is formed by a clamping rail 1 and by a clamping element K1 to Kn arranged next to one another Clamping element exists.
  • the clamping device is used to clamp flat thread layers FS, in particular warp threads and the like.
  • the individual threads forming the thread layer FS run perpendicular to the drawing plane in FIG. 1 and horizontally, that is to say transversely across the drawing sheet, in FIG. 2, and they are generally arranged close to one another.
  • the clamping device according to the invention is a "one-sided", in which the material to be clamped, that is to say the thread layer FS, only needs to be accessible on one side.
  • This page is based on FIGS. 1 and 2 the upper side of the thread layer FS; However, depending on the spatial conditions, it can also be the lower or, in the case of a vertical thread layer, the left or the right or the rear or the front side.
  • the clamping device is positioned on one side of the thread layer FS, as a result of which the position of the clamping rail 1 is fixed on this one side. Now the clamping elements movable relative to the clamping rail 1 have to be brought to the other side of the thread layer FS to form a clamping gap and finally the clamping gap has to be closed.
  • the clamping elements K1 to Kn essentially consist of a bolt 2, which is mounted on the clamping rail 1 so as to be displaceable in terms of stroke, which protrudes with one end from the clamping rail 1 and at this end a wing-like one Clamping part 3 carries.
  • This is formed by a relatively thin lamella, tapered towards its free end, both in length and in thickness, which has approximately the shape of an isosceles triangle carried by the bolt 2 at its base. The length of this base is greater than the distance between adjacent bolts 2.
  • the clamping parts 3 are aligned such that they run parallel to the threads forming the thread layer FS; they are thus rotated by 90 ° with respect to the position shown in FIGS. 1 and 2. In this position, the clamping parts 3 can easily penetrate the thread layer FS. They are then pivoted back by 90 ° and assume the position shown in the figures, in which they form a coherent clamping member and, together with the clamping rail 1, limit a clamping gap which extends over the width of the thread layer FS.
  • the individual bolts 2 are firmly connected in the area of their central part to a support ring or a support slat 4, with which they are supported on a holding member 5 carried by the clamping rail 1.
  • the cross-section of the clamping rail 1 has a corresponding shape, for example a C-shaped profile with a bottom 6, a top wall 7 and a rear wall 8. Between the support rings 4 and the top wall 7 act compression springs 9 which press the support ring 4 against the holding member 5 and thus the clamping elements Kl to Kn down.
  • FIG. 3 which shows a detailed view in the direction of arrow III of FIG. 1
  • the bolts 2 and the clamping part 3 are rotated or pivoted by means of a rod-like slide 10 which extends over the length of the clamping rail 1 , which is articulated with the adjustment arms 11 attached to the individual bolts 2.
  • the adjustment path of the slide 10 is limited such that the clamping parts 3 are pivoted parallel and perpendicular to the threads between the two positions.
  • Fig. ' 3 the clamping position of the clamping elements Kl to Kn and the adjustment arms 11 is full and the immersion position is shown in dashed lines.
  • the described solution of the pivot drive of the bolts 2 by means of a slide 10 and adjusting arms 11 is only one embodiment.
  • Another possibility is to provide the support rings 4 with a toothing on their circumference and to replace the slide 10 by a toothed rack which is in engagement with this toothing.
  • the design of the clamping parts 3 is also to be understood as an example. These could also be formed by a bow made of bent wire or the like.
  • the clamping parts 3 Since, as already mentioned, the length of the clamping parts 3 at their base is greater than the pitch of the bolts 2, the clamping parts 3 overlap one another in their clamping position by a few millimeters. So that the clamping member formed by the clamping parts 3 of the individual elements Kl to Kn has the smoothest possible surface without laterally protruding edges or corners, the clamping parts are correspondingly graduated in their overlapping area.
  • the gradations labeled A are particularly evident from FIG. 3.
  • the holding member 5 is formed by two parallel pairs of racks arranged on both sides along the bolts 2 and each containing a first and a second rack 13 and 14.
  • the first racks 13, which serve as a support for the support rings 4 and thus for the clamping elements K1 or Kn, are flat on their support edge for the support rings 4 and have a toothing on their lower edge.
  • they are arranged in the clamping rail 1 such that they can only carry out a vertical movement.
  • the second racks 14 also have a straight edge and a toothed edge.
  • the straight edge serves as a contact surface on the bottom 6 of the clamping rail 1, and the toothing on the other edge is in engagement with the toothing of the first toothed racks 13.
  • the second toothed racks 14 are arranged in the clamping rail 1 such that they can only carry out a horizontal adjustment movement in the longitudinal direction of the clamping rail 1. This adjustment is carried out by suitable means, for example by a screw 15 (FIG. 1) acting between the clamping rail 1 and the second toothed racks 14 or by an eccentric, a toggle lever, by hydraulic means or by compressed air.
  • the clamping rail 1 is provided on its supporting surface for the thread layer FS which forms the clamping gap with an elastic support 16 made of a suitable material, for example rubber.
  • an elastic support 16 made of a suitable material, for example rubber.
  • a thread deflection can take place at the clamping point, for which purpose the clamping rail 1 can have a groove 17 (FIG. 2) along the clamping line.
  • the pad 16 could be omitted.
  • a a further variant would consist in making this groove wider and deeper and to provide it with an elastic insert.
  • the one-sided clamping device described can be used particularly in the so-called warp preparation, that is when pulling in and connecting warp chains, and is superior to the conventional two-sided clamping devices, especially in the confined spaces such as are present when used on the weaving machine.
