Definitions

  • the invention relates to a dobby according to the preamble of patent claim 1.
  • the radial engagement and disengagement of the coupling wedge in the eccentric ring while the drive shaft is at a standstill is triggered by a switching element arranged with a circular opening, approximately concentric to the drive shaft.
  • the circular opening has a collar projecting over the switching arm over the entire circumference, which collar is constantly in engagement with a sliding groove of the coupling wedge.
  • the switching element is tiltably mounted in the plane of its circular opening, its movement during the control process of engaging and disengaging the clutch wedge inevitably taking place from the control system of the dobby when the drive shaft is at a standstill.
  • the switching element is freely movable, so that it is carried along by the coupling wedge which swivels with the drive shaft by 180 °, via the sliding groove and the collar, in accordance with the movement of the coupling wedge, which ensures that this Switching element for its actual switching function, against which the clutch wedge is always ready for use.
  • the coupling wedge lies in a sliding groove of the eccentric ring during its swiveling movement by 180 ° and is carried along by the drive shaft.
  • springs are arranged in the clutch wedge.
  • the connecting rod has resilient, semicircular guide rails against which the coupling wedge can rest.
  • the object of the invention is to eliminate these uncertainties in the course of the movement of the coupling wedge and to eliminate the additional, special, costly and complicated guiding and holding elements for the coupling wedge, while maintaining a safe control process.
  • the annular switching member is always slidably in the groove of the coupling wedge in a known manner, but acts there, contrary to the prior art, also during the rotation phase of the coupling wedge as its guide.
  • the switching element is subject to a non-positive control movement and a positive locking during its guide function, the annular guide part being in a concentric position with the drive shaft.
  • the known holding and guiding elements can thus be omitted. Nevertheless, there is a guarantee that the control element will be in the working position in front of the groove of the drive shaft or the stationary latching opening when the coupling wedge is at a standstill.
  • the latching opening is preferably located on the machine frame or on the connecting rod in which the eccentric ring is rotatably mounted.
  • the main shaft 2 is rotatably mounted as a drive for the rotary lifting unit seated on it.
  • the drive part not shown, rotates the shaft with a stop that repeats itself periodically after 180 °.
  • the clutch wedge 3 which is mounted with its extension 34 in the slot 43 of the annular eccentric disc 4 in an adial slidable manner, can be controlled.
  • the eccentric disc with the freely rotating connecting rod 5 seated on it is freely rotatably mounted on the drive shaft.
  • the free end 50 of the connecting rod 5 is articulated via the bolt 56 on the rocker arm supported on the shaft 60, at the free end of which the connecting rod 7, which moves the heald frame in a known manner via intermediate levers, not shown, is articulated.
  • the heald frame is in the vertical position, which is achieved when, in the embodiment variant shown, the coupling wedge 3 is located in relation to the drive shaft 1, on the free end 50 of the connecting rod 5 Side.
  • the switching arm 8 which serves to control the coupling wedge 3 is pivotably seated on the first shaft 80 and has a circular control opening 82 which is formed by an annular collar 83 which projects beyond the plane of this switching arm 8 and always engages in a sliding groove 38 of the coupling wedge 3.
  • a tab 11 is articulated at one end and in between on the differential lever 12 at its other end.
  • One end III of the differential lever is connected to the rocker arm 6 via the rail 13, while the pulling hook 14 is articulated at the lower end I, being pulled by the reciprocating tension knife 15 against the force of the spring 81.
  • the reading process of the branch needle 17 attached to the pulling hook 14 is initiated, which slides in the guides and thereby the full or high positions of the card cylinder 9 in steps, i.e. Shot by shot sponsored luster card 19, reads.
  • the guide rake is designated by 110, in which the pocket 11 is guided such that the differential lever 12 remains positioned in its movement path.
  • the two prongs 84 of the switching arm 8 result in three notches 21, 22 and 23 at the free end of the switching arm, against the flanks of which the locking bolt 24 bears during its latching movement.
  • Fig. 1 shows the position of the dobby when changing the shaft position.
  • the drive shaft 2 rotates through 180 °, i.e. it is in the turning phase.
  • the stylus 17 was seated on a full position when it was lowered onto the sample card 19, and since the locking bar 24 was pulled up, the free end of the switching arm 8 has been pivoted to the left under the force of the spring 81.
  • About the collar 83 of the switching arm and the sliding groove 38 of the coupling wedge this has been moved to the left until it engages in the latching opening 35.
  • the locking bolt 24 is lowered into the detent 21 until the flank on the flank of the switching arm and bolt rests (drawn position in FIG. 1).
  • the heald frame was brought into the down position via the rocker arm 6, where it remains during the rotation of the drive shaft 2.
  • the stylus 17 has been raised by the rod 16 and the card cylinder 9 can extend the sample card 19 by one shot, i.e. an information point, switch on.
  • one shot i.e. an information point, switch on.
  • FIG. 2 shows the dobby after the drive shaft 2 has rotated 90 °, starting from the situation according to FIG. 1, at a standstill, one of the grooves 20 being in the range of motion of the coupling wedge 3.
  • the rod 16 is lowered and, in the example shown, the stylus 17 reads a hole, as a result of which the pull hook 14 is lowered until its hook tip rests on the pulling knife 15, from which it is carried when it is pulled out.
  • the upper end I of the differential lever 12 is no longer in contact with the guide rake 110, but is about the articulated connection III with the rail 13, which, since it cannot move in its longitudinal extent due to the stoppage of the rocking lever 6, in the drawn Position swiveled.
  • the locking bolt 24 Since the locking bolt 24 is raised during the control operation of the stylus 17, when the differential lever 12 is pivoted, the switching arm 8, under the pull of the tab 11, also acts against the force of the spring 81 pivoted.
  • the coupling wedge 3 is inserted into the groove 20 via the collar 83 of the switching arm and at the same time moved out of the notch 35.
  • the locking bolt 24 is lowered into the central catch 22, as a result of which the switching arm 8 remains blocked in the position in which the control opening 82 is concentric with the drive shaft 2.
  • FIG. 3 shows the state of the dobby which, in comparison to FIG. 2, is distinguished by a rotation of the drive shaft 2 by 90 °.
  • the heald frame is in the middle position. Due to the pivoting movement of the rocker arm 6, the differential lever 12 is pivoted, via the rail 13 and the articulated connection 111 has reached and the pull hook 14 has been lifted up with the stylus 17 from the rod 16, so that the sample card 19 can be advanced through the card cylinder 9.
  • FIG. 4 again shows a switching position for the clutch wedge after the 180 ° rotation phase of the drive shaft 2 has been completed, the shaft being in the high position for a weft insertion. If the shaft is to return to the low position for the next weft insertion, the stylus 17 reads, according to the pattern and as shown, a full position of the pattern card 19.
  • the pull hook 14 remains above the tension knife 15 and is not carried along by its pulling-out movement.
  • the upper end 1 of the differential lever 12 lies against the guide rake 110. Under the action of the spring 81, the switching arm 8 remains in its position even after the locking bolt 24 has been released, since the differential lever 12 remains as feedback from the rocking lever 6 via the rail 13 in the drawn, pivoted position (FIG. 4).
  • the position of the clutch wedge 3 with respect to the drive shaft 2 remains unchanged.
  • the change of position of the shaft due to the rotation phase of the drive shaft 2 can proceed normally.
  • the eccentric disc 4 moves the connecting rod 5 to the left and the shaft is brought into the controlled low position by the rocker arm 6.
  • the shaft machine operates according to FIG. 5, again showing the standstill phase of the drive shaft 2.
  • the locking bolt 24 is disengaged, the stylus 17 has read a hole in the sample card 19, the pulling hook 14 has been pulled out by the pulling knife 15, which pulling out then causes the differential lever 12 to pivot about the articulated connection 111 of the differential lever 12 / rail 13.
  • the clutch arm 3 is pulled out of the groove 20 via the tab 11, the switching arm 8 to the right and thus via the collar 83 and the sliding groove 38 and locked into the notch 350.
  • the drive shaft 2 rotates again through 180 °.
  • the locking bolt 24 is guided into the left catch 23, so that the switching arm 8 remains blocked.
  • the clutch wedge 3 is secured by the switching arm 8 against radial movement or by the detent 23 against pivoting movement.
  • a tension spring 81 is provided in order to bring the upper end of the differential lever 12 into the basic position before the pulling movement of the tension knife 15 begins.
  • This spring can be omitted if at the same time as the Pulling movement of the pulling knife 15 acts on a pushing knife 14, not shown, on the pulling hook 14, the stylus 17 of which scans a full position on the sample card 19.
  • the illustrations show how the shift arm 8 is controlled in three positions with the aid of a differential lever 12, the rail 13 and pull hook 14 being the inputs and the link plate 11 being the output in the differential gear.
  • the clutch wedge 3 is guided continuously, both during its standstill, i.e. Disengaged state in front of the drive shaft 2, as well as during its pivoting movement with the drive shaft 2.
  • the switching arm 8 By fixing the switching arm 8 by means of a locking bolt 24 during the non-control phase, no spring acts and in particular also the return spring 81 for the differential lever 12 or the pulling hook 14 , on the contact point between collar 83 and coupling wedge 3.
  • the switching arm 8 has three positions secured by an active or passive locking member for controlling and guiding the clutch wedge 3 by adding a third position to the two usual positions produced by the needlework, or the position of the heald frame or one of its operating levers is derived.
  • the clutch wedge is controlled after every half rotation of the drive shaft. During the control of the clutch wedge, the drive shaft stands still for a short engagement and disengagement time. During the rotation phase of the drive shaft, i.e. the movement time of the shafts between high and low compartment, the control unit reads the desired position of the shafts for the next shot. The control unit maintains the read control position at the beginning of the rotation of the anti-drive shaft.
