Definitions

  • the armor mechanics according to the invention makes it possible to produce a mechanical with pulley for actuating ropes or heddles in which the means provided for selectively driving the pulleys in rotation in one direction or in the 'others are particularly simple, inexpensive and very compact.
  • the rotating member is constituted by a shaft common to at least a certain number of the mechanical pulleys, while the connecting means associated with each pulley comprise a first depression hollowed out in the periphery of the shaft, a second provided in the wall of the pulley bore and a rolling element capable of being housed in the retracted position in the depression of this pulley, things being arranged in such a way that in the rest position of the latter (low position of the arm), the rolling element remains in the depression of the pulley which is then not driven by the shaft, while, when the first and the second depression pass opposite one of the other during the rotation of the shaft in the direction corresponding to the lifting of the heddle, an actuating finger passing through a radial perforation of the pulley can push the rolling element into the depression of the shaft, the latter and that of the pulley being p rofiled in such a way that there is then jamming and that the pulley is driven by the shaft during a mechanical operating cycle
  • the double lift system Another important improvement brought to the armor mechanics is the double lift system, according to which the lowering of the heddles which must pass from the high position to the low position takes place at the same time as the lifting of those which on the contrary must pass from the low position to the high position.
  • the rate of opening and closing of the pitch is doubled, that is to say the weaving speed.
  • the present invention is adaptable to a
  • each pulley there is then associated with each pulley no longer one, but two coaxial rotating members driven in alternating angular motion of the same amplitude and the same frequency with a phase shift of half a period and the connecting means are provided so that they allow the pulley to be connected to that of these two organs which are substantially at the same neutral point as it, that is to say at bottom dead center, if the beam is to be raised, or on the contrary to top dead center, if it is to lower it.
  • the connecting means advantageously comprise, on the one hand, a depression on the periphery of each ring acting as a rotating member and a corresponding depression in the wall of the bore of the pulley, this third depression being sufficiently wide in the axial direction to overlap one or the other of the first two, on the other hand, a ball capable of cooperating with these depressions, the depression of the pulley opening outwards by a radial perforation in which can s '' press a clean actuating finger to act on the ball.
  • FIG. 1 a shaft driven by an alternating rotational movement.
  • the amplitude of this movement is 150 °, it being understood that this is not obligatory.
  • the means used to drive the shaft 1 have not been shown, but they are easy to imagine.
  • idler pulleys 2 On the shaft 1 are mounted idler pulleys 2 on each of which is wound a funicular member 3 preferably constituted by a ribbon (as will be seen below) to which is attached a stringer4 of the loom considered, this stringer being stressed downwards by a return spring 5.
  • Each stringer carries an eyelet 6 crossed by a warp thread 7. Only two pulleys have been shown, but there is obviously a number equal to that of the warp threads or groups of warp threads to be controlled, said pulleys possibly being distributed over several shafts 1 arranged side by side, if desired.
  • the angular stroke for lifting the shaft 1 will be that which takes place in the direction of the arrow 10 and by which the pulley 2 in question is driven with the shaft by lifting the beam 4 which is associated with it. .
  • shaft 1 a top dead center position (at the end of the 150 ° following arrow 10) and a bottom dead center position corresponding to the end of the 150 ° rotation in opposite direction to the said arrow.
  • This same terminology can also apply to pulleys, as will be better understood below.
  • each pulley 2 In the periphery of the shaft 1, there is provided at the right of each pulley 2 a depression 1 a, which, when the shaft is in bottom dead center, is located in the lower zone thereof, slightly beyond from the position shown in fig. 2 in the return direction (opposite direction to that of arrow 10), know more exactly as indicated in section in fig. 4.
  • the pulley 2 itself also assumed to be at the bottom position of the heddle to which it corresponds (bottom dead center of this pulley) has in its internal bore, by which it is mounted on the shaft 1, a depression 2a, but which continues towards the outside by a through perforation 2b. As shown in fig.
  • the depressions 1a and 2a are profiled so as to comprise upstream relative to the arrow 10 an inclined plane 1b, respectively 2c, while, downstream, the first 1a ends in a wall 1 c with a quarter-circle profile and the second 2a by a straight wall 2d oriented approximately radially.
  • an actuating finger 12 suitable for engaging in the perforation 2b to push the ball 11.
  • This finger has a bevel 12a on its downstream edge relative to the arrow 10. It is carried by an arm 13 articulated at 14 (fig. 4) to the mechanical frame and it is urged towards the pulley 2 by a spring 15.
  • the arm 13 is made of iron or mild steel so as to ability to cooperate with an electromagnet 16 capable of holding it in the lowered position against the reaction of the spring 15.
  • Fig. 8 shows the position of the parts a little after the ball 11 has been thus jammed. It can be seen that, thanks to its bevelled downstream edge 12a, the finger 12 has been pushed down against the reaction of the spring 15 and that it therefore does not hinder movement. It only slides on the periphery of the pulley. We thus arrive at the top dead center of the shaft 1 (position in fig. 9). The pulley 2 is then in the position in which its beam is lifted to the maximum (top dead center of the pulley). Then the shaft 1 performs its return stroke, the ball 11 remaining in the stuck position thanks to the return force exerted by the spring 5 (fig. 1) associated with the beam considered. When the radial perforation 2b of the pulley 2 returns in front of the finger 12, the cleat 8 abuts against the common cross member 9 by stopping the pulley 2 at its bottom dead center. Two cases can then arise:
  • the electromagnet 16 does not have to control the lowering of the arm 13 since, in any event, this arm is positively lowered by the effect of the bevel 12a at the start of rotation of the pulley 2 (position in fig. 7) and by the ball 11 at the end of the cycle, as shown in figs. 4 and 11. Therefore, the intensity of the control current can remain relatively low, which is important for the production of mechanical or other switches.
  • the depression 1 a of the shaft 1 can be produced in the form of a profiled longitudinal groove, common to all the pulleys 2, which simplifies the machining. Furthermore, instead of a ball 11, it is equally possible to envisage using a roller.
  • the depression 1 a of the shaft can be produced in the form of a profiled longitudinal groove and the ball 11 can be replaced by a roller.
  • the presence of the pin 17, which must remain oriented towards the pulley, requires that the funicular member 3 be made in the form of a ribbon or the like.
  • the electromagnet 16 does not have to command the lowering of the arm 13 except at the time of the initial selection.
  • the exploded view of fig. 16 and the sections of fig. 17 and 18 show an embodiment of the invention specific to the implementation of the double lift system.
  • the pulley 2 no longer rests on a single rotating member (which, in the two previous embodiments, was constituted by the shaft 1), but on two members produced in the form of rings 18 and 19 juxtaposed on the 'shaft 1 (as shown in phantom in Fig. 16 for clarity of the drawing), which is, again, driven by an alternating angular movement.
  • the ring 18 is wedged on this shaft, as indicated by the key 20 in FIG.
  • the two rings 18 and 19 are, apart from that, identical in their details, but they are turned opposite one another. In other words, it can be considered that, if we disregard the keyway of the ring 18 and the wheel 21 associated with the ring 19, each of them presents the image of the other view. in a mirror.
  • the pulley 2 has an internal depression 2a, but provided sufficiently wide to extend over the two rings 18 and 19, as shown in FIG. 17.
  • This depression opens, again, outside through the perforation 2b.
  • Each ring has, like the shaft 1 in FIG. 2 for example, a depression 18a, 19a suitably shaped to receive about half of the ball 11 (inclined plane 18b, curved wall 18c).
  • these depressions lead to that of the lateral faces of each ring which faces the other.
  • each ring is hollowed out on the periphery of a local bevel 18d, 19d inclined transversely towards the other ring, respectively 19, 18, this bevel being arranged at a point such that it comes opposite the depression of this another ring when said depression is opposite that 2a of the pulley 2 assumed at top dead center or bottom dead center.
  • Figs. 16 to 28 includes the actuating finger 12, as well as the open step groove 2e and the pin 17 (as in fig. 12).
  • the ring 18 will now carry out its forward or lift stroke in the direction of the arrow 10, the ring 19 rotating in the opposite direction. If the finger 12 is lowered, nothing happens, the ribbon 3 remains low. If, on the contrary, this finger is lifted by the corresponding spring (spring 15 in fig. 4), the ball is applied against the two rings, as shown in figs. 10 and 20, the first being a partial plan view below, the pulley supposed to be removed to allow the rings to be seen, and the second a detail section on an axial plane passing through the center of the ball 11.
  • the depression 18a of the ring 18 as well as the bevel 19d of the ring 19 appear progressively above the ball 11 (position of FIGS. 21 and 22).
  • the ball engages therein, but the bevel tends to push it laterally towards the ring 18 so that it penetrates more and more into the depression 18a, as shown in FIGS. 23 and 24.
  • the ball 11 is entirely housed in the latter (FIGS. 25 and 26) thus constituting a pawl or key between the ring 18 and the pulley 2, which is trained in the lift stroke.
  • the open pitch system does not work (finger 12 lowered), the pulley 2 will go back (return stroke), and so after. If, on the contrary, the finger 12 remains biased by its spring, it engages in the open pitch groove 2e of the pulley and retains it in the raised position of the corresponding rail (or, if preferred, of the tape 3 to which this beam is attached).
  • Fig. 31 shows another variant, in which the rings 18 are no longer keyed onto the shaft 1, which can be fixed, but have toothed wheels 25 engaged with pinions 26 wedged on another secondary shaft 27. It will be understood that this does not change anything during operation. In this figure, we assumed that we had adopted the dual alternation 19, 19, 18, 18, etc., the two adjacent rings 19 or 18 can be made in one piece, but this obviously does nothing mandatory.
  • the diameter of the pulleys and the shaft can be arbitrary.
  • the shaft and the pulleys becoming linear organs.
  • the connecting member consists of a ball, a roller or the like, it could just as easily be produced in another form, in particular in that of a loop established at the end an elastic blade fixed in a shallow recess made on the periphery of the shaft 1, this loop being urged by the blade in the centrifugal direction.
