Definitions

  • the invention relates to an arrangement for controlling the sinkers in a jacquard machine, in which each sinker is operatively connected to an impression element that can be moved between two positions, in which one Stelluna the respective sinker is available for engagement with a lifting knife that can be operated between two specialist positions, or a stationary locking knife and in the other of which the respective circuit board is deflected such that it is out of engagement with the lifting nuts or the locking knife.
  • the arrangement for controlling the vertically arranged blanks has impression elements that can be moved horizontally.
  • a so-called needle structure consisting of needles which can be selectively moved horizontally between the two positions is provided, with such a needle being associated with the sinker and being able to be pivoted by the latter in a vertical plane between the two desired positions of the sinker .
  • each needle has a deflection in its horizontal course, which encompasses or ripens on the associated circuit board. Since the boards are arranged in a grid for reasons of machine size, and a pin must be assigned to each board, a staggered arrangement of the needles is necessary, which is why the point of contact of the needles on the boards is different in each grading level.
  • Jacauard cards are scanned by means of a Finlesevorrichtuna, in which the pattern or the desired position of the boards is stored in that either a hole is provided or not.
  • the corresponding circuit board is deflected (pressed) or not via an impression device. It has already been suggested to carry out this reading process by electromagnetic means (see, for example, PS 93 513, DE-OS 22 35 225).
  • the horizontal movement of the needle to adjust the respective circuit board is controlled electromagnetically here in such a way that, depending on the state of excitation, the electromagnetic control element prevents the circuit board from pivoting or is reached.
  • the jacquard card can be replaced by electronic data carriers which use electrical signals to control the electromechanical control elements. Since a staggered needle structure is also provided here, the needles of which can be moved horizontally, the disadvantages described above also occur. Since the vertical extent of the staggered needlework cannot be increased arbitrarily for mechanical-dynamic reasons, there is also very little space available for the electromechanical control elements, which is why it is extremely difficult to provide control elements which ensure reliable function and a long service life can
  • the impression element is arranged essentially parallel to the respective board and is adjustable between the two positions with pivoting entrainment of the respective board.
  • the electromagnetic control element can be arranged so that it only has a holding function, but does not have to perform any lifting work, which is achieved in that the top end of the impression element moves the armature of the electromechanical control element in any case in such a way that the armature of the electromechanical control element moves in a stroke cycle Air gap is bridged. In addition to safe operation, this also enables a reduction in the power consumed and thus a reduction in heating, which in addition to saving energy also contributes to the increased service life.
  • the structure of the jacquard machine is explained below as far as is necessary to understand the present invention.
  • the principle is that the E rfinduna can be used with any jacquard machine that essentially uses the same control of the boards, regardless of whether the boards are moved vertically, horizontally or at an angle.
  • a plurality of essentially rod-shaped blanks 1 are arranged in a regular grid and can be moved vertically up and down in the exemplary embodiment.
  • the movement of the sinkers 1 takes place by means of lifting knives 2 and 3, in which the upper ends 8 of the sinkers 1 can be suspended and which can be moved up and down synchronously with the working cycle of the weaving machine.
  • the lifting knives 2,3 can assume two end positions, namely an upper shed Stel Luna H or a lower shed position T. Fine first Hubmesseren with the lifting knives 2 is in the lower shed position T when a second Hubmesserarupne with the lifting knives 3 in the H ochfachstelluna H, and vice versa.
  • the boards 1 In the position T of the boards 1 corresponding to the low position T, they sit at the lower end on a board base 5 such that the upper end 8 of the board 1 can be offered to the lifting knives 2, 3 for removal or can be withdrawn from them.
  • the nose 6 In the high position H of the circuit board 1, the nose 6 is located above the locating knife A locking knife 7, the upper end 8 being in engagement with one of the lifting knives 2, 3 so that the nose 6 can be anaeboten or detached from the locking knife 7 for holding .
  • the lifting blade is reverse to 2.3 brinaen of Tieffach- in the upper shed position or the circuit board depending on a superiors g plane patterns inside or outside the effective ranges of the lifting knives 2,3 or Arretiermesser. 7 This is achieved by a corresponding deflection of the board 1 to the lifting knife and locking knife level.
  • each board is assigned a needle which is movable perpendicular to its direction of movement, that is to say horizontally in the exemplary embodiment, between two positions, the needle taking the respective board into the pivot positions to be controlled and one of the two positions corresponds to the explained deflection in the vertical plane.
  • the respectively assigned needles are staggered, that is to say to be arranged in several horizontal planes, which requires a considerable amount of space again different pivot angles for the different boards. Due to the vertical space required for the needlework, the boards have to be made correspondingly long. Furthermore, there are undesirable leverage effects when the lateral control takes place here. Different leverage ratios occur.
  • the pivoting takes place in substantially the same plane as the movement of the circuit board 1, namely by means of a rod-shaped impression element 9 which is adjustable between two positions and thereby pivots the associated plantine 1 a position holding the print element 9, the board 1 so that the lifting knives 2,3 entrains the board 1 in such a manner and during the movement from the lower shed Stel Luna T in the Hochfachstellunq H that ochfachwolf during movement of the lifting blade from the 3.2 H H in the low position T the nose 6 of the respective board 1 comes into engagement with the locking knife 7.
  • the impression element 9 pivots the associated circuit board 1 so that in the lower shed position T, the upper end 8 is pivoted to the plate 1 so that, in the BEWE the lifting knife g una from the Tieffachstellunq T in the upper shed Stel Luna H 2,3 those corresponding Board 1 is not taken, or in such a way that when moving from the high position H in the down position T the nose 6 near the bottom end of the circuit board 1 is brought out of engagement with the locking knife 7 and therefore the circuit board 1 is lowered past the locking knife 7 onto the board base 5.
  • a driver element 10 is formed between the impression element 9 and the associated circuit board 1 in such a way that the circuit board 1 and impression element 9 can be displaced relative to one another and independently of one another.
  • the entrainment takes place expediently at the point at which the lever ratios and the impression paths for the high position and the low position T of the circuit board 1 are optimal.
  • either play is provided between the flanks 11, 12 and the plantine 1, or the surface of the flanks 11, 12 is spherical.
  • To ermöalichen an easier installation of print element 9 and board 1 in this jacquard machine, engages around the catch element 10, the board 1 merely convenient finger-like and not ponderearti g.
  • a pin 13 of a driver element 14 engages in a length slot 15 of the board 1, the pin 13 having a circular cross-section for the reasons mentioned.
  • Such a design could be useful if the board 1 is formed by two essentially parallel rods.
  • Fixed guides 16 are provided within the jacquard machine frame for guiding the circuit board 1 and the impression elements 9, the course of which corresponds to the division of the grid and which run essentially parallel to the lifting knife plane and the pivoting plane. Insofar as the pivoting of the plates 1 and the impression elements 9 remains ensured, such guides can also be provided perpendicularly thereto in the plane perpendicular to the direction of movement, as will be explained below.
  • impression elements 9 can be controlled selectively for the purpose of pivoting the respective circuit board 1 or for the purpose of pivoting it back. It must therefore be possible to pivot the imprint elements 9 according to the pattern in the working cycle of the weaving machine.
  • Jaoguard cards there is the possibility of reading in via mechanical scanning using so-called Jaoguard cards and using electromechanical scanning, in which a mechanical element of an electromechanical component can assume two defined positions depending on the control by electrical signals.
  • this control takes place by means of a conventional needle mechanism with needles that can be moved horizontally in the exemplary embodiment and with mechanical or electromechanical control with the loading peculiarity that in the vertical direction there is no significant spatial restriction.
  • the triggering of the impression elements 9 can take place directly by mechanical and preferably by electromechanical means. It is of particular advantage that the grid dimension available for the control elements corresponds to that of the circuit board, which is why the restriction regarding the size of the electromechanical actuating elements is significantly reduced.
  • a gradeluna in the direction of movement of the circuit boards 1 does not have the same importance in the actuation of the impression elements 9 as in the actuation of the circuit boards by means of a needle mechanism with horizontally movable needles according to the prior art.
  • impression elements 9 are pivotable in such a way that the pivoting path in the area of the driving element 10 (or 14) is essentially the same for all boards 1.
  • An impression element 19 which can be pivoted about a shaft 18 which is stationary around a jacquard machine frame has an anchor element 20 which, in the embodiment shown, rips away on the side facing away from the impression element 19 with respect to the shaft 18.
  • Each armature element 20 and thus each impression element 19 is assigned an electromagnet 21 which is de-energized or energized in accordance with the pattern to be achieved.
  • the air gap 22 is ensured by means of the spring force. However, in this embodiment, considerable forces may be required to ensure that the air gap 22 is bridged when the electromagnet 21 is energized or the air gap 22 is restored when the electromagnets 21 are de-energized, and the corresponding deflection of the circuit board 1 is ensured.
  • the anchor element can also be mechanically offered to the magnet 21 to overcome the air gap.
  • the principle of operation consists essentially in that the impression element 9 is moved up and down by means of an impression meter 25, which can be cyclically synchronized with the work cycle of the weaving machine, is moved up and down, and, depending on the excitation state of an electromotive device 26, is locked in an upper position is, or is taken into a lower position by the impression meter 25. A mechanical deflection takes place in one of the two positions, taking the associated respective circuit board 1 with it.
  • each electromagnet 26 is associated with a downward-projecting armature 27, which has a hanging opening 28 at the lower end.
  • the upper end 29 of the impression element 9 has a hook recess 30 on the side facing the associated anchor 27.
  • the spatial assignment of the hook recess 30 on the one hand and the fin hanging opening 28 on the other hand is such that in an energized position of the electromagnet 26 when the impression element 9 is moved up and down, the hanging opening 28 and hook recess 30 cannot come into engagement, while in the other energizing position the fin opening 28 and hook recess 30 engage securely.
  • the upper end 29 of the impression element 9 has a corresponding nose 31 or a hook.
  • a spring force is expediently effective between the upper end 29 and the impression meter 25, as is shown schematically by a symbol for a spring, by means of which the nose 31 of the upper end 29 is moved against the impression meter 25 in a twofold manner.
  • the stroke cycle for the impression meter 25 is shown in FIG. 1 in the order A-D for actuation without deflection of the circuit board 1 and in the sequence D-G for actuation with deflection of the circuit board 1. It should be mentioned that all impression meters have the same position depending on the movement of the lifting knives 2, 3 or the machine, and that the different phases are explained by the representation according to A - G.
  • the electromagnet 21 is entreated, that is to say that an air gap 33 is present between the armature 27 and the electromagnet 26 or the yoke thereof.
  • the uppermost stroke position A is the hook recess 30 vertically above the hanging opening 28 and has mechanically deflected the armature 27 slightly or completely in the direction of bridging the air gap 33.
  • the armature 27 folds or swings back, possibly using a restoring force, for example a spring force, with the air gap 33 regressing.
  • the electromagnet 21 If the electromagnet 21 is now energized (in accordance with the sequence E -G), the armature 27 bears against the electromanete 26 or its yoke under the air gap 33. Especially when the armature is pivoted completely over the air gap 33 in the upper position F, which corresponds to the position A, the electroma network 26 only has to exert an adhesive force in order to hold the armature 27 on the electromagnet 26.
  • the impression knife 25 is lowered from the upper position E, the nose 31 of the upper end 29 of the impression element 9 remaining in the recess (F and G) with the impression knife 25, and the hanging opening 28 and the hook recess 30 do not come into contact with one another, such that the impression element 9 safely reaches the lower Stelluna G with the help of the spring preload by the spring 32.
  • deflection chamfers are provided, namely, on the one hand, a deflection chamfer 34 on the underside of the hook recess 30 and a deflection chamfer 35 on the top of the upper end 29.
  • the tongue-shaped anchor 27 can have a corresponding curve 36. If necessary, instead of a hook recess 30 with an associated deflection slope 34 and the deflection slope 35, a nose can be provided, which is provided on the upper end 29 of the impression element 9.
  • the pivoting of the impression element 9 takes place in one of the two positions with pivoting entrainment of the respective circuit board 1 with the aid of the driver element 10 or 14. It must now be ensured that the deflection is ensured in one of the two positions of the impression element 9 while in the other this is avoided.
  • the impression element 9 in its course in the exemplary embodiment advantageously near the lower end but expediently below the vertically lowermost lacre of the lifting knife 2 in the deep position T, is assigned a control cam element which interacts with a corresponding guide 39.
  • the cam element is formed by a cam 38 on the impression element 9, which cooperates with a stationary horizontal guide 39 in the position in which a Auslenkunq is to be achieved. This is shown in position G in FIG. 1, in which the cam 38 has run onto the guide 39 via a slope 40 and is thus pivoted relative to the point of attack between the nose 31 and the impression meter 25.
  • the driver element in the lower shed Stel Luna T has 10 so pivots the board 1 to the attachment p oint on the platinum bottom 5 that the upper end of the board 1 is 8 is no longer in engagement with the lifting blade.
  • the associated driver element 10 has pivoted the board 1 around the suspension in the lifting knife 3 via the upper end 8 such that the nose 6 of the board 1 is pivoted above the locking knife 7 in such a way that when the lifting knife 3 is subsequently moved downward, the nose 6 is moved past the locking knife 7.
  • the control cam element can also be designed in a different way.
  • a curve piece 41 can be provided on the impression element 9, which has corresponding curve courses 42 and 43 on both sides, which in turn are in constant contact with respectively assigned guides 44 and 45. This ensures a positive working method.
  • the control cam element can also be formed by a depression 46 in the impression element 9, into which a corresponding guide 47 engages, which comes into active engagement with a flank 48 of the depression 46 for deflection.
  • guides 50 corresponding to these, but perpendicular to them, are further provided in the frame.
  • the guide 39 or 44, 45 or 47 and the cam element assigned to them do not necessarily have to be below the lowest position of the lifting knife 2 in the deep position T, these elements can also be above the uppermost position of the lifting knife 3 are in the Hochfachstelluna H, however, the embodiment shown is easier to implement.
  • the guides 50 and the guides 39, 44, 45 and 47 can also serve as guides for the plates 1 and for resetting the impression elements 9. The latter in that the impression element 9 is braced during the deflection (position G).
  • This tension can e.g. can be avoided by providing a recess 52 with flanks 53 in the area of the guide 50 50 on the impression element 9 (FIG. 6) such that as soon as a control curve element (cam 38 or recess 46) via the associated flanks with the guides 39, 44 , 45, 47 is in operative connection, the impression element 9 can pivot freely without bending. When resetting, the impression element 9 is then positively returned to its original position via a flank 53.
  • the electromets 26 are preferably provided in a common holder 51 which can be connected to the machine frame, as a result of which the wiring and thus the electrical connection can be provided in a simple manner for controlling the electromagnets 26.
  • the driver element 10 and the control curve element with associated guide 39 can also be used.
  • the control curve element can be achieved by bending or bending.
