Definitions

  • the invention relates to a device for coupling a heald frame, each with an upward and downward movable shaft holder extending laterally of the heald frame side supports by means of coupling means that can be locked using the toggle lever principle.
  • the heald frame has an upper and a lower cam on its side support, which is why the heald frame holder must accordingly also have two counter cams interacting with them and the heald frame holder therefore one for bracing the cams lying at a distance from each other and having a special construction that requires the entire shaft holder height.
  • the tensioning using the toggle principle therefore also takes place in the vertical direction connecting the two cams, but in which direction the heald frames also oscillate during operation. In the clamping device effective in the vertical direction using the toggle principle, obviously no spring force is involved.
  • the aim of a technically better solution for connecting the heald frame and shaft holder results in creating a suitable coupling device with little space requirement, especially above the heald frame, in which the pressing force is effective transversely to the oscillating direction of movement of the heald frames and with this force limited areas of the heald frame and shaft holder are held pressed against one another in positive engagement, so that no relative movement between the parts in the direction of their up and down movement is possible.
  • the objective also includes that the usual heald frame should have as little design change as possible, in particular that there should be no cams protruding from the side, and that the heald frame and shaft holder must be connected quickly and easily.
  • the device has the features of claim 1.
  • the device according to the invention has the advantages that the closure can be actuated quickly and with a handle, the actuation lever of the closure extending in parallel somewhat above the upper heald frame.
  • the heald frame itself has no laterally protruding parts and only has to have a latching recess on the inside for the toggle lever and driving surfaces for the form-fitting coupling with the shaft holder. It is also advantageous that the pressing force caused by the toggle lever tensioning device is perpendicular to the up and down movement of the oscillating moving web shaft is effective.
  • FIG. 1 consists of an upper shaft rod 1 and a lower shaft rod 2 and two side supports 3 and 4, which together form a rectangular frame.
  • the side supports 3 and 4 have a U-shaped cross section.
  • a shaft holder 5 with a rectangular cross section fits into this cross section and is shown in broken lines in FIG. 1 on the left side.
  • Such a shaft holder 5 is to be connected to the heald frame on the left as well as on the right side and is used for moving the heald frame up and down in the weaving machine, wherein the pulling means 5, not shown, act on the hooks 6 at the upper and lower ends of the shaft holder.
  • a claw 7 is screwed with an inclined surface, with which the shaft holder engages behind the beveled lower end of the side support 3 in a hook-like manner.
  • the closure 8 arranged at the upper end of the shaft holder and working according to the toggle lever principle is used, which is shown in FIGS. 2, 3, 5 and 6 in different positions.
  • 4 shows that the side support 3 or 4 is U-shaped in cross-section and the shaft holder 5 is rectangular in cross-section and projects between the legs of the U.
  • driving surfaces in the form of a toothed strip section 9 at the upper end of the shaft holder 5 and in the form of a further toothed strip section 10 on one are transverse to the drive direction of the oscillatingly movable shaft holder 5 Formed piece 11, which is screwed onto the upper end of the side support 3, as can be seen from FIGS. 3 and 5.
  • the toothed rack sections 9 and 10 are in engagement with one another when the closure 8 is pivoted into the locking position, as can be seen from FIG. 6.
  • strips which are integrally formed and have a U-shaped cross section are riveted to the upper and lower ends of the shaft holder.
  • a pivot axis 13 extends through the bar 12 and the shaft holder 5 at the upper end, about which the closure 8 can be pivoted between the open position according to FIG. 5 and the locking position according to FIG. 6.
  • the closure 8 has a pair of levers 14 and 15 which are of the same design and are arranged parallel to one another and which can be pivoted about the pivot axis 13. Near the other end facing away from the pivot axis 13, the actuating lever 17 is pivotably articulated on the lever pair 14, 15 by means of a further axis 16.
  • the actuating lever which is designed as a hollow bar, has an elongated hole 18 on opposite sides, through which the axis 16 extends, so that the actuating lever 17 is not only pivotable about the axis 16, but is also longitudinally displaceable due to the elongated hole 18.
  • a stepped pin 19 is arranged, through which the axis 16 extends, so that the bolt 19 together with the hollow rod 17 is pivotable about this axis 16.
  • a nut 21, which fits into the hollow rod 17, is screwed onto the threaded end 20 of the bolt 19.
  • the hollow rod 17 is a square tube into which a smaller square tube piece 22 fits, which is pinned to the hollow rod 17 and thereby forms an inner collar fixedly arranged in the hollow rod 17, through which the bolt 19 extends.
  • One end of a compression spring 23 is supported on the inner collar 22, the other end of which is supported on the nut 21. This compression spring 23 is installed with a strong pre-tension so that it is compressed to about 4/5 of the spring travel.
  • the actuating lever 17 In the unlocked state of the closure 8 according to FIGS. 2, 3 and 5, the actuating lever 17 is therefore laterally displaced relative to the axis 16 as far as the elongated hole 18 formed in the actuating lever 17 permits, which with its right edge is against the Axis 16 abuts, as shown in Figures 2-5.
  • the advantage of the strongly pre-tensioned compression spring 23 is that when the lock is pivoted into the locking position according to FIG. 6, a strong spring force is exerted to hold the lock in the locking position, for which only a very small spring travel is necessary.
  • the strength of the bias of the compression spring 23 can also be changed by turning the nut 21.
  • the actuating lever 17 has at its front end on the left in the drawing a printhead 24 in the form of a bolt which is wedge-shaped at the front and riveted into the hollow rod 17.
  • a groove-shaped latching recess 25 is formed for the press head 24, which is supported in this latching recess in the locking position of the closure according to FIG. 6.
  • a pin 26 penetrating the pin 19 is provided, which protrudes outwards on both sides of the actuating lever 17 through a larger hole 27 on both sides, the larger hole allowing the relative movement between the pin 19 and the actuating lever 17.
  • This pin 26 interacts with an end edge projection 28 formed at the end of each of the two levers 14 and 15, which serves as a stop and limits the pivotability of the actuating lever 17 relative to the pair of levers 14, 15, as shown in FIG. 3.
  • Fig. 5 shows the closure in a position before the coupling of the heald frame and shaft holder, but also the end position when uncoupling.
  • the cross-sectionally U-shaped side support 3 has two legs which lie in the same plane as the levers 14 and 15 of the pair of levers. These legs of the side support 3 are cut curved at their upper end so that a small Area 3a of the leg protrudes further upwards. Against this area of the two legs of the side support, the levers 14 and 15 come to rest with a lever corner lying at the bottom in the open position of the closure according to FIG. 5, so that the shaft holder 5 moves the levers 14 and 15 into the position according to FIG.
  • the closure 8a is articulated on the heald frame, specifically on the shaped piece 11 which is attached to the side support 3 of the heald frame and carries the toothed strip section 10.
  • This fitting 11 extends between the two levers 14 and 15 of the pair of levers.
  • the actuating lever has a hollow rod 17 and a bolt 19 extending therein on its longitudinal axis.
  • a fork-shaped part 30 is fastened, which is pivotably mounted in the shaped part 11 by means of a joint pin 31.
  • the lever pair consisting of the levers 14 and 15 is pivotably articulated on the actuating lever 17, 19 by means of an axis 16, while the other ends of the two levers 14 and 15 are connected to one another by a cross bolt 32.
  • a recess 33 is formed, in which the cross bolt 32 engages when the closure 8a is brought into the locking position.
  • the mode of action inside the operating lever 17, 19 is here the reverse of the mode of operation in the first embodiment, ie when the operating lever is pivoted into the over-center position, the bolt 19 moves within the elongated holes 18 in the hollow rod 17, the prestressed compression spring 23 being further compressed.
  • the two embodiments are identical and corresponding parts are designated by the same reference numbers.
  • the shaft holder 5 is expediently connected at one end to the heald frame by means of the claw 7 mentioned at the beginning by engaging behind the side support 3 and at the other end of the shaft holder the connection between the heald frame and the heald frame is made with the help of the lock operating according to the toggle lever principle, however an embodiment is also possible in which a closure operating according to the toggle lever principle is provided at the upper and at the lower end of the shaft holder.
  • an actuating lever 35 which is substantially simpler in construction is U-shaped in cross-section, that is to say it consists of only one part and is by means of an axis 36 which extends through the two legs of the U-shaped lever connected to two outside levers 14 and 15, which are articulated at their other end by means of the pivot axis 13 on the shaft holder 5.
  • this embodiment corresponds to that according to FIGS. 6 and 7.
  • a longitudinally extending leaf spring 37 which is curved in the transverse direction is arranged.
