Definitions

  • a double-stroke open-pocket jacquard machine is a shedding device for weaving machines that enables irregular patterns to be woven.
  • the sinkers intended for lifting and lowering the warp threads are taken along by reciprocating lifting knife boxes, for which purpose the sinkers are provided with lugs for hanging on the cutting edges of the lifting knives.
  • the boards are controlled by needles extending transversely to them when the lifting knives are in their stroke end positions. If a board is to remain in the upper compartment, it is supported with a nose on a locking knife and therefore cannot follow the lifting knife. If a board is to remain in the lower compartment, it is supported on the board base and the needle must press the board off the associated lifting knife to avoid taking the board with it.
  • the basic object of the invention is to avoid this undesirable entrainment of descending boards by ascending lifting knives.
  • this basic object is achieved in that one of the two lifting knives in the intersection x area of the plates from its predetermined vertical movement path ; evades laterally. The descending boards can therefore no longer be detected by the ascending lifting knife due to this lateral evasion path.
  • the lifting knives are spaced from one another so that they do not cross each other during their lifting movement.
  • the boards are double-legged, one leg acting as a resilient support leg and the other leg being provided with three lugs, which point in the same direction, two lugs of which are assigned to the lifting knives and one lug to the locking knife.
  • Board grates are arranged between the lifting knife sets and below the lower lifting knife set, which limit the freedom of movement of the boards in the impression direction of the needles.
  • the lateral evasive movement of a lifting knife box thus has the result that the boards hanging thereon are supported on the board grids, while the area of the board located between them is bulged, ie deformed, by the laterally evading lifting knife.
  • This deformation of the boards leads to the fact that the board leg located above the board grids with the free hook attached to them is brought out of the effective range of the ascending knife.
  • the special object of the invention is to avoid the disadvantages of the construction according to DE-PS 23 44 363 by supporting the boards on board grids by means of a different design of the boards and arrangement of the board grids with the consequence of the bending of the board is avoided if one of the lifting knife boxes executes a lateral evasive movement.
  • the invention is based on DE-PS 23 44 363 in that the lifting knife boxes are spaced apart from one another, i.e. they do not cross, whereby s one of the knife boxes, preferably the one below, performs a lateral evasive movement in the crossing area of the boards and thus the unwanted taking of the downwards prevents the board from going up by the lifting knife.
  • a board grate is arranged between the knife boxes, on which the boards are guided with the possibility of evasion in the direction of impression of the needles.
  • the boards are designed according to the invention in one leg, secured against rotation about their axis and their lugs assigned to the lifting knives are directed towards opposite sides, the boards in the impression direction of the needles on the grating arranged between the lifting knives, avoiding another, below the Lifting knife arranged grate are supported and an additional grate is provided above the open compartment position of the upper lifting knife.
  • a double-stroke open pocket jacquard machine according to the invention is shown in an overall view. It has two groups of lifting knives 6, 7 which can be reciprocated in the vertical direction and which are so far apart from one another that they do not cross. With these lifting knives 6,7 boards 1 are moved vertically, which in turn by impression needles 5 transversely to their longitudinal axis are adjustable so that the lugs 2, 3 located on the single-bar plates 1 and projecting in opposite directions can be brought into or out of engagement with the knife edges of the lifting knives 6, 7. Each board 1 also has a locking lug 4, which can cooperate with a stationary locking knife 8 in the upper compartment position of the board 1.
  • the impression needles 5 are moved laterally by impression knives 17 acting horizontally against the action of springs, not shown.
  • the stylus needles 19 are connected to the impression needles 5 and act against the jacquard cards 21, which are guided in the usual manner via a cylinder 20. If a stylus 19 hits a hole in the card 21, it brings the imprint needle 5 assigned to it out of the range of action of the imprint knife 17. The consequence of this is that the assigned board 1 remains in its basic position, that is to say it is not pressed. If, on the other hand, the stylus 19 hits the card 21, then the impression knife 17 moves the associated impression needle 5 and thus also the associated circuit board 1.
  • Fig. 1 the upper lifting knife 6 is shown in its upper and the lower lifting knife 7 in its lower stroke end position.
  • the boards 1a are located in the sub-compartment and are not pushed off to the side. Consequently, they are taken up with the lifting knife 7.
  • the boards 1 b are in the upper compartment and are also not pulled off. Consequently, they would go down with the lifting knife 6, but they are prevented from doing so by being supported on the locking knife 8.
  • the boards 1 c are located in the upper compartment and are pushed off to the side. Since they hang with the lugs 2 on the lifting knife 6, the locking lug 4 is released from the locking knife 8. Consequently, these boards 1 c go with the lifting knife 6 in the lower compartment position.
  • the boards 1 d are in the sub-compartment and are pressed. As a result, the nose 3 is released from the lifting knife 7, from which it follows that the boards 1 d remain in the sub-compartment position.
  • a grate 9 On which the boards 1 are guided in their basic position and support them when they are pressed.
  • the boards 1 located in the lower compartment are seated on a board bottom 10.
  • a second grate 12 is provided in the area of the upper stroke end position of the upper stroke knife 6, , the function of which is described in more detail in the following figures. If the boards 1 c located in the upper compartment are pressed briefly and thus follow the lifting knife 6 into the lower compartment position, the ascending lifting knife 7 and the free nose 3 of the descending board 1 c meet, which would result in this board 1 c recorded halfway and taken back to the upper compartment. This would make a weaving mistake inevitable.
  • one of the lifting knives 6, 7, preferably the lower lifting knife 7, executes a lateral evasive movement along the arrow 13 when the free nose 3 is about to pass the lifting knife 7 rising upwards.
  • Gearboxes for such avoidable knives are known, so that a constructive representation is unnecessary.
  • FIGS. 2 to 9 show the different positions of the boards 1 as a function of the reading process.
  • the boards 1 are in the down position.
  • the associated needles 5 have not been pushed sideways, consequently the lower lifting knife 7 will take the board 1 in the case of FIG. 2 into the open compartment position.
  • the lifting knives 6, 7 have reached their other stroke end positions compared to FIG. 2, so that the upper knife 6 takes the board 1 into the open compartment position.
  • the plate 1 is properly centered in that it rests on the grate bar 9 facing the nose 2 and possibly on the locking knife 8 and is held in this position by the tensile force of the harness thread.
  • the circuit board 1 is laterally pressed off by the needle 5, it is subject to a combined bending and tilting stress, counterclockwise around the grate 9, whereby the middle nose 3 from rising Lift knife 7 is released. If the upper part of the board is stiffened and the lower part of the board is soft, then the board 1 more tilts around the supporting grate 9 in the upper area and more bends in the lower area.
  • the printed circuit board 1 printed according to FIG. 4 thus remains in the sub-compartment position as in the example of FIG. 5, which corresponds to the position of the lifting knives 6, 7 according to FIG. 3. It can be seen from FIG. 5 that the tilting movement of the circuit board 1 must assume such an angular dimension that the upper nose 2 closest to the grate 9 is clearly distanced from the plane of movement of the lifting knife 6.
  • the circuit board 1 is in the open compartment position and sits with its nose 4 on the locking knife 8. It is not fired, so it remains in the open position. Here, too, the circuit board is properly guided and centered between the grate 9 and the locking knife 8.
  • the upper grate 12 is functionally important because it blocks the tilting movement of the board 1 in the upper part.
  • Suitable guide means 14 are provided so that the boards 1 can get into the position between the grate bars 12 without resistance or blockage, which in the example of FIGS. 2 to 9 consist of a slightly angled extension of the board.
  • FIG. 9 it is now shown how the circuit board 1 going down with a lifting knife 7 is prevented from catching its free nose 2 by the lifting knife 6 going up.
  • the lower lifting knife 7 regularly executes a lateral evasive movement, as indicated by the arrow 13, while passing through its middle lifting range.
  • the hanging board 1 is taken from the dashed position into an inclined position so that its nose 2 is released from the knife 6. This movement of the board takes place without deformation because it detaches itself from the grate 9 by the lateral entrainment of the knife 7 and has already got out of the upper grate 12.
  • a single circuit board 1 is shown in a constructive representation.
  • a stiffener 11 in the form of a wire is attached to the circuit board 1, e.g. welded in a plane parallel to the needles 5. This stiffening also results in a turnstile for the board, in connection with the usual guide rods that extend parallel to the needles 5.
  • the stiffening 11 carries the upper nose 2.
  • a part of the circuit board 1 protruding beyond the nose 2 is slightly angled. and forms a guide means 14 for easier insertion of the circuit board 1 into the grate 12.
  • the grate 12 can also be provided with guide means 14, which can even protrude down to below the nose 2 of the boards located in the lower compartment position.
  • a circuit board 1 provided with an offset 15 is shown, which extends in the impression direction of the needles 5.
  • the type of bend 15 is selected so that the circuit board 1 in the sub-compartment position (cf. FIG. 4) is influenced by the needles 5 at a point above the bend (15).
  • these offsets 15 are also an anti-rotation device for the circuit board 1.
