Definitions

  • the present invention relates to improvements made to the system for selecting the hooks of a weave mechanism in order to allow the production of shaped fabrics, that is to say requiring a very large number of warp threads to be raised or lowered.
  • Such fabrics constitute paintings, tapestries or other engravings for which manual looms have been used until now.
  • Such an armor mechanism is very complex and requires significant precision in the production of all of its elements in order to guarantee the relative position of each blade relative to its electromagnet and to the lifting plate. It is provided with a large number of mobile elements so that to avoid any premature wear and in order to obtain the precision essential for the realization of all the elements, one arrives at a very high cost of such a mechanical .
  • the invention overcomes these drawbacks. It is aimed at armor mechanics with a very large number of hooks, of the type in question which is economical compared to the devices proposed until then, requires low consumption of electrical energy during operation and is particularly suitable for armor wires high density yarn, that is to say of the order of one hundred yarns per centimeter in large width.
  • Figures 1 and 2 schematically show an armor mechanism established in accordance with the invention in the closed crowd and open oblique crowd positions, respectively.
  • Figure 3 is a large-scale vertical section of the hook selection system.
  • Figure 4 is an exploded view.
  • Figures 5 to 8 are views similar to that of Figure 3 but illustrating the selection system at its different positions.
  • Figure 9 is an alternative embodiment of the ramp intended to offset the blades.
  • Figure 10 is a view similar to that of Figure 3, but showing another way to perform the retention of the blades.
  • FIG. 11 is a diagram of the electrical circuit intended for the operation of a module of the selection system.
  • FIG. 1 and 2 there is illustrated very schematically in FIG. 1 and 2, an armor mechanism comprising application of the improvements according to the invention.
  • This mechanism essentially comprises two mobile plates 1 and 2, one lower carrying the hooks, the other upper supporting the selection system.
  • Each of the plates is connected by a link 3, 4 to a bent pendulum 5, 6 articulated around a fixed axis 7, 8.
  • the bent part of the pendulums assumes the shape of a fork 7a, 8a whose ends of the branches are associated with free rollers 7b, 7c respectively 8b, 8c which cooperate with cams and cams 9.
  • the rotation of the latter which are wedged on a rotating shaft 10 causes the rockers 5 and 6 to tilt and the platens to move vertically 1 and 2.
  • each of these has an external finger 1a, 2a which moves in opposite slides 11a, 11b of a vertical slide 11.
  • Each plate has a roller 12, respectively 13, mounted freely at the end of a bracket 1b, 2b and which is located inside a slot 14, respectively 15, of a fixed plate 16.
  • Each slot 14, 15 comprises a vertical part 14a, 15a which ensures a displacement of the two plates parallel to themselves, then each lumen is rounded so that after having carried out their course parallel to themselves corresponding to the selection phase, the two plates come in oblique position as illustrated in fig. 2.
  • the plate 1 is provided with holes 1c intended for the passage of the hooks 17 of the armor mechanism according to the invention.
  • the upper part of the hook has a spout 17a below which there is a bulge or heel 17b which comes to rest in a housing 18a of a guide 18 associated above the plate 1 by means of an assembly bolt 19.
  • the housing 18a is at the upper end of a vertical conical bore 18b formed in the guide 18 in correspondence with the hole 1c of the plate 1.
  • the upper plate 2 supports the modules 20 of the selection system, each module being intended for the control of twenty four hooks.
  • Each module 20 comprises a support 21 made of non-magnetic material such as a thermoplastic resin, which comprises centering pins 21a engaging in corresponding holes 2c of the plate 2.
  • the support 21 is first of all associated with a single pole piece 22 produced in the form of a flat plate extended by tongues 22a bent at 90 ° relative to the general plane of said plate to form teeth 22b, 22c offset longitudinally.
  • This pole piece 22 is shown in detail in FIG. 4, on which we can clearly see the offset of the teeth 22b and 22c in the height direction. It is also observed that the teeth 22b are shorter than those 22c.
  • the pole piece 22 is assembled to the support 21 by means of bolts 23 which also hold a comb 24 whose blades 25 oriented downwards, cross the plate 2 in openings 2d.
  • the end of each blade 25 is bent upwards to form a lug 25a intended to cooperate with the spout 17a of the corresponding hook 17.
  • the bolts 23 also hold a panel 26 in which is printed the control circuit of the coils 27 engaged around the teeth 22b and 22c of the pole piece.
  • a permanent magnet 28 is disposed parallel to the underside of the plate 2 in a cavity 21b of the support 21.
  • the different supports 21 are assembled together by means of centering devices not shown, the supports being fixed to the plate 2 to the hub of clamping screws 29 engaged in tapped holes formed in a fixed bracket 30.
  • the permanent magnetic circuit is interrupted for example by feeding the coil 27 arranged around the tooth with which the blade is in contact, as soon as the two plates move away from the lug 25a of the blade 25 will cooperate with the ramp 18c to enter the spout-17a of the hook 17 (fig. 8); under these conditions the hook considered will be selected, that is to say that the warp thread with which it is joined will be raised.
  • fig. 9 Illustrated in fig. 9 a variant in which it is the hook 17 itself which carries the deformation ramp of the blade 25. To do this its heel 17b is extended so as to constitute said ramp. The underside of the heel then comes to rest against a flat 18d of the guide 18.
  • a printed circuit embedded in the panel 26 As it is a question of ordering a very large number of coils referenced 27 1 to 27n independently of each other, the printed circuit has been installed very close to the coils to reduce the length of the conductors.
  • the control information from the selection reader is sent by a single wire 32 (fig. 11). This information results in a shift register 33 of known type.
  • the register command introduces the first information into its first box 33a.
  • the information for the second coil is then presented at the entry of the register 33.
  • the shift command then places the content of box 33a in box 33b and places the information for coil 27 2 at 33a.
  • the information for the coil 27 3 is then presented, then the shift command passes the contents of boxes 33a and 33b into those 33b and 33c, while the information for the third coil is entered in box 33a.
  • the information arriving as the shift register operates is carried out in the same manner until the information for the last coil 27n is introduced. There are therefore only two wires for controlling all the coils which are preferably 24 in number. It then remains to excite the latter from the information contained in the register 33.
  • Each module therefore includes a power supply with two circuits.
  • the first which is produced by means of the conductors 34 which can have significant lengths brings the current to the terminals of a capacitor 35, thus placed in bypass with respect to the supply of the circuit 34.
  • the supply of the capacitor can therefore be carry out under a permanent current of very low intensity (close to ten milliamps), which allows a significant reduction in the diameter of the supply wires 34, while the overall permanent current remains low (of the order of 5 amps).
  • the second circuit is intended for supplying the coils from capacitor 35.
  • each of the boxes of the shift register 33 is connected to the coils 27 1 to 27n by means of a switch i which receives the information from said register 27n by a conductor 36.
  • the circuit d is closed. 'supply of said switches by means of a power switch 37 provided with a protection 38.
  • the switch 37. is preferably a power transistor capable of withstanding the overvoltage caused by the self induction of the coils at the time of the power cut . It is only after the total extinction of this current that the switches i can be operated.
  • the shift registers are then reset to zero so as to stop the current consumption for controlling the switches i. This saves energy and considerably reduces the temperature rise at the level of the printed circuits while increasing reliability.
  • the coils have been separated into two groups, that is to say those associated with the teeth 22b and those which are mounted around the teeth 22c.
  • the coils of the first row are fed first, then that of the second.
  • the distance between the neighboring coils supplied at the same time is increased the interaction between their flux decreases.
  • the time separating the two power supplies being very small (less than a millisecond) the selections can be considered to be confused from the mechanical point of view, the corresponding difference in positioning of the plates being less than 0.5 millimeter.
  • Armor mechanics have thus been produced intended for controlling a very large number of hooks, the selection system of which is made up of separate modules is arranged very precisely relative to the upper plate.
  • the arrangement of the magnetic circuit eliminates any air gap adjustment between the elastic blade and the pole piece and any distance adjustment between said blade and the hook.
  • the disassembly or the installation of the modules is very easy because of their extremely simple assembly.
