Definitions

  • the present invention relates to a shaft support for holding a replaceable heald frame in a weaving machine with two lateral vertical legs provided for cooperation with guides on the loom side, at one end of which the shaft is supported by a support element and at the other end a locking element, which is considered to be from the respective leg locking cam projecting in the direction of the other leg is provided for fixing the supported shaft in at least the vertical direction, the support element having a rigidly designed bearing surface on a horizontal bar for the shaft and the locking element having a stop surface facing it, and wherein the locking element for unlocking the Shaft is designed to be pushed horizontally outward from its locking position into its unlocking position.
  • the US-PS 2 131 679 shows a shaft carrier of the type mentioned with two vertical legs running in the loom-side guides, in which a replaceable heald frame can be clamped at its lateral edges. At the end of the vertical legs, bolts are provided which can snap into the shaft by spring pressure. For Unlocking, the bolts are pressed outwards against the spring force, so that the shaft is released.
  • This arrangement has the advantage that a shaft change can be carried out without tools and, moreover, only a short time is required for this manipulation, which reduces the unproductive time of the weaving machine.
  • the springs for securing the bolts are designed as horizontal coil springs, which can lose their function due to contamination.
  • the invention solves this problem in that the locking elements are rigidly connected to the respective vertical leg and this is under the action of a spiral spring, and in that the vertical leg is connected to the horizontal bar via a swivel joint.
  • This arrangement ensures precise and secure mounting of the shaft, which allows high machine speeds.
  • FIG. 1 shows a loom 1 with side walls 2, 3 and guides 4, 5 arranged thereon for a heald frame 6 which can be moved vertically up and down Shaft drive device with known transmission elements 10, 11, 12 for positive shaft drive is connected.
  • the lower shaft 13 of the heald frame 6 rests on a horizontal beam 14 which connects the two vertical legs 15, 16 of the shaft support 7 to one another to form a U-shaped support frame.
  • Locking elements designed as locking cams 17, 18 encompass the shaft 6 with stop faces 19, 20 at the corners of the upper longitudinal side 13a, so that this is arranged without play at least between ends 14a and 14b of the horizontal bar 14 acting as support elements and the stop faces 19, 20 and on the other hand between the vertical legs 15, 16.
  • fixing jaws 21, 22 are provided, which are attached to the front and rear of the horizontal beam 6 and, in the manner of a clamp, secure the shaft 6 together with holding wings 23, 24 fixed to the locking cams 17, 18 from slipping or sliding out of the shaft carrier .
  • Each vertical limb 17, 18 is provided with a weakening point 15, 16, which allows the limbs 17, 18 to be resiliently pivoted outward about an axis perpendicular to the plane of the shaft movement and thus to bring the locking cams into the unlocking position by horizontally outward displacement. Furthermore, the vertical legs 17, 18 are provided with an extension 27, 28 which complement the U-shaped support frame 7 to an H-shaped configuration and thus, together with the correspondingly extended guides 5, 6 of the weaving machine 1, ensure improved lateral guidance of the shaft support.
  • the drive movement is transmitted by the dobby 8 through a drive rod 10, deflected at the transmission member 11 designed as a toggle lever, and introduced into the horizontal bar 14 by a further drive rod 12.
  • this particularly simple shaft drive device is unable to give the shaft 6 any directional stability during the movement, as is the case, for example, with conventional shaft drive devices acting on the two lower corners of a shaft. Due to the improved guidance with the help of the extensions 27, 28, there is no danger that the shaft support will tilt.
  • the guides 4, 5 are withdrawn towards the outside into the sides 2, 3 of the weaving machine 1, which allows the vertical legs 15, 16 to pivot about their pivoting joints 25, 26 designed as weakening points and thus the locking cams 17, 18 away from the upper shaft side 13a and pulled outwards into the unlocked position.
  • the spring-elastic weakening points have a certain spring force acting in the locking direction, which supports a play-free adjustment of the locked shaft 6;
  • Fig. 2 shows one part of a two-part, a further embodiment corresponding shaft support. Both parts 27 are constructed identically, each run in a guide 4, 5 of the weaving machine sides 2, 3 and face each other in such a way that they can each engage one side region of the shaft 6. Each vertical leg 27 has a support element 29 with a rigid bearing surface 30 for the shaft 6 and a locking element 32 which can be pivoted about an axis 31 and has a stop surface 33 for the upper longitudinal side 13a of the shaft 6.
  • a shaft drive device designed in the manner of the negative shaft drive engages in a manner known per se via a pull cable 34 on an extension 345 of the vertical leg 27 in the pull-down direction and via a return spring 36 in the pull-up direction on the vertical leg 27.
  • This arrangement allows the shaft 6 to be unlocked by pivoting the locking elements 32 about the axis 31 out of the shaft movement plane and has the advantage of fulfilling all the necessary requirements with regard to shaft holder and shaft change with the simplest construction with maximum weight savings due to the lack of a horizontal bar.
  • Fig. 3 shows the upper end 37 of a vertical leg 15; the other vertical leg 16 is identical and omitted to relieve the figure.
  • a locking element designed as a slide 38 serves to lock the shaft 6; its stop surface 39 is in contact with the upper longitudinal side 13a of the shaft and thus holds the shaft 6 in position.
  • the vertical leg 15 has a horizontal groove 40 and a vertical groove 41 with a T-shaped arrangement in cross section.
  • the horizontal groove 40 guides the slide 38 through a upper guide surface 42 and two lower guide surface sections 43; the vertical groove 41 lies in the sectional plane of the figure and opens between the guide surface sections 43 into the horizontal groove 40 and contains a substantially vertical spiral spring 44 which projects into a bore 45 of the slide 38 and acts on it in the locking direction.
  • the slider 38 is provided with a vertical section 46 which, on the one hand, forms a stop against the pressure of the spiral spring 44 for the locking end position and, on the other hand, enables the slider 38 to be gripped by hand and pushed outward into the unlocking position. Since the slide 38 is guided firmly by the horizontal groove 40, the spiral spring 44 can be held in the bore 45 in a sliding manner, which allows it and, as a result, the vertical groove 41 to be formed briefly, if desired.
  • This arrangement has the advantage that the locking of the shaft according to the invention can also be used in the case of a rigid U-shaped shaft support frame, which is advantageous with certain stranded frames; in addition, there is no risk that increased wear will occur during operation of the weaving machine when the shaft carrier is running empty.
  • Fig. 4 shows the one vertical leg 47 of a shaft support with which another vertical leg 45 cooperates in the manner of a clip on the same shaft side.
  • the other side of the shaft support because it is of identical design, is omitted to relieve the figure.
  • Each vertical leg 47, 48 has a spring-elastic weakening point 49, 50 with a horizontally extending pivot axis 51, 52 and a locking element 53, 54 fixed at the end. This arrangement allows the shaft 6 to be gripped like a clamp, with a collar 55 on Vertical leg 47 additionally secures the shaft 6 in the horizontal direction. Below the weakening points 49, 50, the legs 47, 48 are connected to one another, which allows conventional guidance in the corresponding guides 4, 5 of the weaving machine.
