Definitions

  • the invention relates to a device for shedding a jacquard machine with the help of between a high and a low position in a frame slidably guided boards and a lifting device for the boards, each of which is stored in the frame, by means of a control device
  • Control element adjustable transversely to the displacement path of the circuit boards can optionally be coupled with the associated driver stops of the lifting device are.
  • the warp threads that form the compartment are used to train jacquard machines between a high and a low position with the help of a Circuit board suspension moves, each on a roller train connecting two circuit boards attacks (EP 0 287 921 A1). These paired boards can, depending on their control, with two reciprocating lifting knives to be coupled to the respective warp thread of the sinker to shift one to the other position. It is also known (EP 0 207 529 A2), not for the adjustment of the sinker per warp thread to provide two, but only one board, which in turn with one of two opposing stroke knives can be coupled.
  • the invention is therefore based on the object of a device for training to design for a jacquard machine of the type described at the beginning, that a considerable simplification of construction and thus a higher functional reliability can be guaranteed.
  • the invention solves the problem in that the driver stops the lifting device from a stop-limited driving position into a Rest position outside the movement path of the counter stops of the circuit boards are pivotable and that the controls on the one hand a cam track for swivel adjustment of the driver stops of the lifting device and on the other hand, have a stop for the boards in the high position.
  • the driver stops of the lifting device can be pivoted to store so that these driver stops on the associated controls can be optionally adjusted, the Connection of the boards with the lifting device can be controlled without the Boards themselves crosswise to their path of movement between the high and the To have to relocate low-level position.
  • the driver stop is for the board to be controlled in its stop-limited driving position, the associated circuit board can be lifted into the respective device other specialist position are moved. It is only necessary to ensure that the Boards supported in the respective specialist position against the tensile load be attacking them through the board hangers. This is for the low bay position in a conventional manner, e.g. B. over a board bottom, possible. In the high position, a stop for the controls is used.
  • the controls need only in Area of this low position cam tracks for the driver stops to have, if it is ensured that the driver stops of the lifting device outside the cam tracks of the controls into the stroke limited Return driver position.
  • the driver stops against a reverse torque from the stop-limited driving position be swingable.
  • Such a return torque can be caused by a spring loading of the driver stops can be ensured.
  • the controls with a cam track to swing out the driver stops from the stroke-limited position in the area of Low position and with a cam track for swiveling in the driver stops equip to take-away position in the area of the high specialist position, which makes spring loading of the driver stops superfluous.
  • the actuating movement of the controls can be different because of it the only thing that matters is a lateral shift of the controls either provide the stop for the boards in the high position or the driver stops, particularly in the area of the low compartment to pivot. Nevertheless, particularly advantageous design relationships can be achieved in that the controls over a inclined guide slot on a common guide axis and with the help of electromagnets in a raised end position are.
  • the adjustment of the control elements along an inclined guide slot, in which a fixed guide axis engages brings a combined Movement of the controls on the one hand transversely and on the other hand in the direction of the displacement of the boards with itself, so that the adjusting movement of the Control elements via the circuit boards or the driver stops of the lifting device can be done.
  • the electromagnets are used only for Hold the upper end position of the controls.
  • control elements on a common pivot axis can be rotatably supported and over the circuit boards or the driver stops to pivot the lifting devices in order to turn a corresponding Ensure control movement transverse to the displacement path of the boards.
  • the rotatable mounting of the control elements on a common swivel axis brings larger with increasing distance from the swivel axis becoming adjustment paths with a parallel displacement of the controls can be avoided.
  • To hold the swung out End position of the pivotally mounted control elements can again be electromagnets be used.
  • the lifting device can be the pivotable driver stops form load-bearing lifting frame, the controls in this lifting frame are guided so that they can be pivoted to the Driver stops in the rest position of these driver stops do not can dodge.
  • the warp threads forming the compartment are 1 passed through eyelets 2 of a sinker 3, which in the embodiment is formed by harness cords 4, but can also consist of healds.
  • These harness cords 4 are suspended at one end in a board base 5 and guided around a deflection roller 6 of the respectively associated board 7. With at the other end, the harness cords 4 grip the associated tension springs 8 on the harness cords 4 regardless of the position the board 7 are kept taut.
  • the guidance of the harness cords 4 over guide rollers 6 of the plates 7 has the advantage that the eyelets 2 are shifted with the double displacement path of the boards 7.
  • the hub the lifting device 9 provided for moving the boards 7 can therefore comparatively small.
  • the lifting device 9 for the boards 7 consists of a lifting frame 10, in which is provided for each circuit board 7 a driver stop 11, which by one Axis 12 between a stop-limited driving position and a Rest position outside the path of movement of the counter stops 13 Boards 7 can be pivoted. This pivoting takes place over the individual boards 7 assigned control elements 14, which according to FIGS. 1 to 4 on a common guide axis 15 via an inclined guide slot 16 stored and adjustable along their guide slots 16. In the The upper end position, the control elements 14 by associated electromagnets 17 can be held optionally.
  • the control elements 14 each form one Holding stop 18 for the boards 7 in the upper high position, whereby the boards 7 with a nose 19 on the associated holding stops 18th support, as shown in FIG. 1.
  • the controls 14 point above also a support arm 20 for a cam track 21, which is used for swivel adjustment the associated driver stop 11 is used.
  • a support arm 20 for a cam track 21 which is used for swivel adjustment the associated driver stop 11 is used.
  • the pivotable driver stop 11 of the lifting frame 10 in the low position on the cam track 21 on, whereby the driver stop 11 from the stop-limited Carrying position in a rest position outside the movement path of the Counter stop 13 of the board 7 is pivoted out.
  • a Weight load or a return spring may be provided.
  • a further cam track 22 is provided on the control element 14 in the area the high position for a forced swiveling back of the driver stops 11 provides, as can be seen in FIG. 2.
  • the position of the control element 14 follows 1, the circuit board 7 via the holding stop 18 of the control element 14 in the high position held while the lifting frame 10 moves up and down becomes.
  • the control element 14 when lifting over the lifting frame 10 in its upper end position held the electromagnet 17 excited via a control device, during the lifting frame 10 supporting the board 7 in the down position is moved.
  • the displacement of the control element 14 along the guide slot 16 causes a release of the nose 19 of the board 7 by the Holding stop 18.
  • the driver stop 11 must the path of movement of the counter-stop 13 of the board in the rest position be pivoted out, which is achieved by the control element 14, the after dropping from the electromagnet 17 with the cam track 21 in the track of the driver stop 11 protrudes and ensures its pivoting, such as this can be seen in FIG. 3.
  • control elements 14 stored and adjusted differently.
  • the embodiment according to the 5 shows a slot guide of the control elements corresponding to FIGS. 1 to 4 14, however, the electromagnets 17 have lifting armatures 24 which connected to a control element 14 and in the direction of the guide slot 16 are attracted to an excitation of the electromagnet 17, like this is shown in dashed lines.
  • a return spring 25 represents the starting position of the Controls 14 after excitation of the electromagnet 17 safely.
  • 6 and 7 show control elements 14 which are about a common pivot axis 26 are rotatably mounted.
  • 6 is one of the controls 14 associated armature plate 27 by the energized electromagnet 17th attracted what a sticking of the control element 14 in the dashed Has pivot position.
  • 7 the electromagnets 17th provided with lifting anchors 24 according to FIG. 5, but with the lifting anchors 24 are articulated on the control elements 14.
  • a return spring 25 ensures again after excitation of the driven electromagnet for the starting position of the control element 14.
  • the electromagnet 17 each excited to move the board from the given position into each to shift other specialist position.
  • the controller is the respective Technical position must be known in order to avoid incorrect switching.
  • To 8 and 9 determine the respective excitation state of the electromagnet 17 the specialist position.
  • the cam track 21 of the control element 14 designed so that the driver stop 11 in the by the Electromagnet 17 held, upper end position of the control element 14 (Fig. 8) is pivoted into its rest position, which maintains the low position the board 7 conditionally.
  • the electromagnet 17 is to be de-energized, as shown in FIG. 9 is.
  • the driver stop 11 is accordingly in the driving position pivoted so that the board 7 is raised by the lifting frame 10, until the nose 19 of the circuit board 7 on the holding stop 18 of the control element 14 is moved past, during the subsequent downward movement of the lifting frame 10, the board 7 from this stop 18 in the high position to hold on.
