Definitions

  • the present invention relates to dobbies and the like. weaving mechanics for crowd training on weaving machines, and it relates more particularly to electromagnetic selection actuators which, in conjunction with reading devices, provide control mechanics of this type depending on the armor to be produced on the fabric being woven.
  • Document FR-A-2 515 703 (STAUBLI) describes a device actuator of this kind which includes a series of electromagnets in number equal to that of the mechanical blades, i.e. amplifier systems and smooth carried by the weaving machine. Electromagnets, supplied through the reading device according to the armor program, are assembled on a single chassis which is driven by an oscillating movement linked to that of mechanics and which carries, on each blade, a pivoting selector associated with elastic means which tend to separate it from poles of attraction of the electromagnet considered.
  • Each selector is thus driven by an alternative movement which approach and move it cyclically away from the tails of the two actuators ensuring control of the amplifier system envisaged, the selection between the two organs of each pair being operated by the corresponding electromagnet, according to whether or not it is powered by the reading device of the mechanical.
  • the object of the present invention is more particularly to remedy the aforementioned drawbacks of conventional devices, and this by arranging each pivoting selector so that it give a motion amplification coefficient such that its selective displacement takes place in a clear and precise manner despite a very low air gap value.
  • the invention essentially consists in providing each pivoting selector of a movable armature which is articulated on said selector by its end turned towards the axis pivot it, and to associate with this frame mobile elastic return means which act on the opposite end in order to maintain the latter at permanent contact of the corresponding pole of the fixed armature of the electromagnet envisaged and, while thus ensuring by reaction the selector recall to the discarded position, to move away the opposite side of this selector from the other pole of said fixed armature, thereby creating the air gap necessary for functioning of the whole.
  • the actuating device according to FIG. 1 is mounted on an oscillating frame formed by two lateral arms 1 connected by a longitudinal cross member 2.
  • Each of the arms 1, mounted on a fixed axis 3, is equipped with a roller 4 which suitable elastic means maintain in contact with a rotating cam 5, the two cams of the system thus ensuring the cyclic oscillation of the chassis 1-2 around the axis 3, in the manner illustrated by the arrow F 1 .
  • the block is fixed which contains all of the control electromagnets 6 supplied by the reading device (not shown) of the mechanics considered.
  • a pivoting selector 7 mounted on a fixed axis 8 which connects the two arms 1 parallel to the cross member 2 of the chassis 1-2.
  • the selectors 7 are arranged side by side on the axis 8, with minimal play so as to be arranged opposite the poles of attraction of the different electromagnets 6.
  • Each selector 7 is intended to ensure control selective of one or the other of the two tilting members 9 and 10 which ensure the actuation of the blade considered of the mechanical. All of the members 9 are carried by a fixed axis 11 while the pivot axis of the members 10 is advantageously constituted by the tilting axis 3 of the chassis 1-2.
  • each selector 7 is equipped, at the level of that of its edges which is turned in the direction of the electromagnet 6, with a movable frame 12 formed by a plate whose face faces away from the frame 6 a -6 b of each electromagnet 6 is integral with a thin strip 12 a introduced into a cavity 7 a formed in the thickness of the body of the selector, advantageously made of synthetic material.
  • the end of the bar 12 a which is adjacent to the pivot axis 8 is articulated inside its cavity 7 a on a small pivot 7 b , while the opposite end of the frame 12 receives the permanent action of a spring 13 engaged in a blind housing 7 c of the selector body.
  • the tip 7 d which equips each selector 7 opposite the pivot axis 8 is arranged opposite the tail 9 a of the member 9, so that, when in its oscillating movement the chassis 1-2 operates the lowering of the block of electromagnets 6, said tip 7 d comes to bear against the tail 9 a which is thus spaced from the fixed stop 14 against which it was applied by a spring 15 (see fig. 1).
  • the tip 7 d is then placed opposite the tail 10 a of the member 10 which is therefore actuated during the oscillating movement of the chassis 1-2.
  • the air gap visible in fig. 3 is very small, so that the effect generated by the magnetic flux is very large, which makes it possible to have recourse to electromagnets of reduced dimensions and low consumption. Although this air gap is small, the particular geometry of the device creates an amplifying effect and allows a large displacement at the point 7 d .
  • the spring 13 automatically switches selector 7 from position according to fig. 2 to that according to fig. 3.
  • the amplitude of the angular displacement of the selector 7 is limited by the range of the tip 7 d against one or the other of two stops 9 b , respectively 10 b , provided for this purpose at the end of the tails 9 a , 10 has organs 9, 10.
  • Each selector 7 is advantageously produced by injection and molding of a non-magnetic material, inside which is directly embedded the end of the tip 7 d , made of steel.
  • the whole 7-12 is very compact. Its useful stroke is very large and the electromagnet works with very good efficiency, while the inevitable inaccuracies of the system are absorbed by the fact that the movable armature is always in abutment against the fixed armature 6 a -6 b by at least one of its ends.
  • each balance 16 carries two pivoting coupling hooks at its ends 17 which are intended to cooperate with control members 9 and 10, here in the form of tilting hooks which a spring 15 tends to be kept elastically applied against fixed stops 18.
  • control members 9 and 10 here in the form of tilting hooks which a spring 15 tends to be kept elastically applied against fixed stops 18.
  • oscillating chassis 1-2 forming a support for a block of electromagnets 6, each of these ensuring the control of a single selector 7 provided with a movable armature 12 identical to that according to the embodiment of FIG. 1.
  • Each selector 7 is equipped with two points 7 d oriented opposite one another in order to ensure the actuation of the members or hooks 9 and 10 coming from, during the oscillating movement of the chassis 1-2, in contact with ranges 9 a , 10 has hooks.
  • the electromagnet 6 considered is supplied, the movable armature 12 is attracted against the fixed armature, so that the selector 7 switches around its axis 8 and comes to the oblique position shown in broken lines ; the oscillation of the chassis 1-2 continues, but the tips 7 d cannot come into contact with the bearings 9 a and 10 a , so that the members with hooks 9 and 10 are not controlled.
