Definitions

  • the invention relates to a weaving machine with heald frames and bumpers, with which the heald frames are coupled, the bumpers being connected to a shaft drive and the bumpers and shafts each having a coupling part, which coupling parts form a positive interlocking engagement with the shaft coupling, and with a pivotable actuating tool for closing or opening the couplings, the actuating tool being pivotally mounted in the frame of the weaving machine.
  • the actuating tool is essentially formed by a rod with an oval cross-section and engages in a recess in the shaft-side coupling part on the bumper if the shafts are to be coupled or uncoupled from the bumper.
  • the operating tool is pivoted through 90 °, pushing apart two elastic legs of the bumper due to the oval cross section.
  • the actuating tool is rotated further or turned back so that the coupling is closed.
  • the operating tool After coupling the shafts, the operating tool must be removed from the weaving machine as it prevents the bumpers from moving vertically.
  • the actuating tool has a first and second actuating means which are coupled such that both are arranged diametrically opposite and movable with respect to a common pivoting center and extend on both sides of the couplings between the heald frames and bumpers, the first actuating means can be moved in a pivoting movement from the outside against the shaft coupling in order to close it and the second actuating means can be moved in an opposite direction pivoting movement from the outside against the shaft coupling in order to open it.
  • the invention makes it possible to couple or uncouple the shafts at the same time without the use of force.
  • the execution of the actuating tool allows a space-saving construction of the Coupling parts, since the actuating means are arranged outside the shaft coupling.
  • the actuating tool can also have a drive shaft and a crank arm connected to it in a rotationally fixed manner, which projects on both sides of the drive shaft and is connected at the free ends to the first or second actuating means.
  • a second crank cheek can be spaced from the first crank cheek and connected at its free ends to the first and second actuating means to form a frame which encompasses the shaft couplings arranged between the heald frames and the push rods.
  • Operational safety can be improved if a bearing journal is attached to the second crank arm that is aligned with the drive shaft.
  • the actuating means has an axle and a plurality of rollers, which are arranged so as to be rotatable on the axle and can each be brought into and out of operative connection with a single shaft coupling, and that connecting lugs are provided which are arranged between adjacent rollers and with the Axes are connected.
  • the actuating tool forms a torsion-resistant grate, in the spaces between which the shaft couplings can be moved.
  • the actuating tool can be arranged in a stationary manner within the weaving machine since it is in a rest position with a horizontal direction Connecting tabs can be placed in which the vertical movement of the bumpers is not hindered. In this position, it can serve as a guide element for individual bumpers that are not coupled to shafts.
  • the drive shaft of the actuating tools within a weaving machine can be connected to one another and to an actuator by a drive, for example with chains, the actuator being arranged in the shaft drive unit of the weaving machine.
  • a drive device for the actuating tool can be provided, which device has an actuating device, a drive wheel connected in a rotationally fixed manner to the actuating tool and a transmission means which is operatively connected to the actuating device and the drive wheel.
  • the coupling or uncoupling of the heald frames can thus be facilitated in an advantageous manner.
  • FIG. 1 a pair of tabs 11, 11 'are fastened to the heald frame 1 below a support 15 and carry a bolt 12 on which the shaft-side coupling part 10 is located. It has a recess 10 'at the bottom and a pocket 14 with contact surfaces 14' and 14 ''.
  • the coupling part 10 can be inserted vertically into the coupling element 3 with the heald frame 1 according to the direction of arrow A.
  • the coupling element consists of two Coupling wedges 31 and 31 ', which are held together by two cover plates 30 and 30'. In Figure 1, only the rear cover plate 30 can be seen, since the coupling element 3 is shown in section without a front cover plate 30 '.
  • the coupling wedges 30, 31 are firmly connected to the cover plates 30, 30 ', for example by hump welding at the connection points 32.
  • the plates 30 and 30' are circular, segments being cut off outside the coupling wedges 31, 31 ', and have a central one Bore, which forms a bearing surface 27 on a bolt 23.
  • the bolt 23 is seated in a bore of a projection 20 ′ on the coupling part 20 on the shaft drive side.
  • the bearing point 26 of the coupling element 3 on the lower coupling part 20 is therefore the fulcrum of the coupling element 3. It can be brought into different positions by an actuating tool 5.
  • the actuating tool 5 has been pivoted in the direction of arrow C counterclockwise, the lower coupling part 20 being in the open position.
  • a bumper 21 which transmits the stroke movements of the shaft drive according to FIG. 5 to the shaft.
  • the coupling wedges 31 and 31 ' have engagement surfaces 35, 36 and 35', 36 ', with which they are in engagement with bearing surfaces 14', 14 '' after the upper coupling part 20 has been retracted. This is brought into the closed position by moving the actuating tool 5 according to arrow B.
  • FIG. 1 For a clearer illustration, the situation according to FIG. 1 is shown again in perspective in FIG. 2, only the rear plate 30 of the coupling element 3, which is congruent with the front plate 30 ', not shown, being shown. Likewise, only the rear flap 11, which is congruent with a front flap 11 ', is drawn, which on the one hand on the carrier 15, the with the shaft 1 is connected, is attached, on the other hand carries the bolt 12.
  • FIG. 3 shows a side view of the arrangement, in particular the tabs 11 and 11 ', which carry the coupling element 10 on the shaft side, and the plates 30 and 30', which hold the coupling wedges 31 and 31 'together.
  • the whole arrangement is very slim, since up to about 20 heald frames have to be arranged side by side in a weaving machine.
  • the actuating tool 5 is shown schematically in FIG. It essentially consists of a drive shaft 53, which is connected to a pneumatic actuator 55, a crank arm 54, which is non-rotatably connected to the drive shaft 53, and axes 52 and 52 ', which carry rollers 51, 51'.
  • the actuating tool 5 can be pivoted in the direction of the arrows B, C by means of the actuator 55.
  • the lines 56, 56 ' serve to supply compressed air.
  • the weaver After the shafts 1 according to FIG. 5 have been inserted into the weaving machine by a lifting device when changing the article in the weaving machine, the weaver only has to enter a command into the control device 6 of the weaving machine, not shown, so that the actuator 55 actuates the actuating tool 5 in Closed position panned. All inserted shafts 1 are thus coupled to the bumpers 21 of the shaft drive 2. The bumpers 21 are connected via angle levers 22 to push rods 25 of the shaft drive, which in turn are actuated by the weaving machine's shaft machine, not shown.
  • FIG. 6 shows a perspective illustration of the shaft drive of the weaving machine with the actuating tool according to the invention.
  • the heald frames 1 sit between two shaft guides 112, which are accommodated in the frame 110 of the weaving machine.
  • the couplings 9 between the heald frames 1 and the bumpers 21 are encompassed by the actuating tools 5.
  • the actuating tool according to the invention can also be used for other types of shaft couplings, e.g. for a shaft coupling according to the German patent DE 3 541 042 C1 (Grob).
  • the actuating tool 5 is rotatably connected to a drive wheel 59 ', which is connected by a transmission member 59, for. B.
  • a chain with a second drive wheel 59 'and this is connected to an actuator 55 in the shaft drive unit 21'.
  • the actuator can be operated either by hand or with a drive motor 55 'indicated by dash-dotted lines.
  • the bumpers 21 are set in motion by angle levers 28, which are moved by the shaft drive unit 21 by means of push rods 29.
  • Figure 6a shows the actuating tool 5 in its embodiment as a guide grate 5 '.
  • the crank web 54 in which the axles 52, 52 ′ are seated, extends transversely from the drive shaft 53.
  • At the other end of the axes 52 and 52 ' is a second cheek 54', which is connected to an axis 57 ', the latter being aligned with the drive shaft 53.
  • the actuating tool thus forms a torsionally rigid grate, the partial rollers 51 ′′ serving as actuating means for the coupling parts 10 and 20.
  • FIG. 7a shows an open shaft coupling which is provided with a special securing element 40 which takes over the function of the snap coupling 33 in FIG. 3a.
  • the securing element 40 consists of two parts 41 and 42, which are articulated at the point k.
  • the part 41 is movably connected to the shaft drive coupling part 20 at the point g and the part 42 is movably connected to the plate 30 at the point d.
  • a tension spring 43 is attached, which establishes a connection to the point g of the part 41.
  • the securing element 40 has two stable positions, namely the kink position and the extended position, between which it can switch back and forth, whereby it passes a dead center position. In the dead center position, in which the spring 43 is most tensioned, the three positions f, k and g lie on a straight line.
  • the securing element 40 In the open shaft coupling, the securing element 40 is in the kink position.
