Definitions

  • the invention relates to a positioning box of electric actuators for training the crowd on a weaving loom, in particular for controlling the arches of a Jacquard-type weave mechanics, and a loom.
  • the actuators associated with these arches should be arranged one by one compared to others in such a way that they can be individually controlled by an electrical control system and that the arches do not interfere with each other.
  • the actuators in question must be capable of being selectively extracted from armor mechanics for standard control, maintenance or exchange operations.
  • the actuators must be positioned so accurate compared to an electronic power supply board and control.
  • the invention intends to respond by proposing a reception box for rotary actuators electric allowing precise positioning of the different actuators for their cooperation with the arches, a possibility of dismantling one or more of these actuators and controlling them by electrical means.
  • the invention relates to a housing of positioning of electric actuators for the formation of the crowd on a loom, comprising at least one compartment capable of removably receiving at least one actuator in a position such that an arch is suitable for be wound on a pulley driven by said actuator.
  • the compartment or compartments constitute as many housings for electric rotary actuators, which allows rapid intervention on these actuators.
  • These compartments the geometry of which can be defined with precision, determine, by form cooperation with actuators, the orientation thereof.
  • the compartments are arranged in rows and columns substantially perpendicular to the axis of rotation of the pulleys actuators. Thanks to this aspect of the invention, a housing can include a substantial number of compartments, while the actuator pulleys housed in these compartments are arranged side by side, allowing easy access to the whole of these pulleys, in particular when fitting the arcades.
  • the compartment is suitable for receiving several actuators and comprises means for relative positioning of the actuators inside the compartment.
  • Rows and columns of actuators can be created inside the compartment.
  • provision may be made for the means of positioning are ribs extending over part of the transverse dimensions of the compartment or of the pins centering.
  • the housing includes a cover capable of covering the pulleys of actuators.
  • This cover isolates the pulleys and the fluff actuators that are permanently suspended in the air near a textile machine being operation. This increases the life of these devices which, if exposed to tamper, would have tendency to clog and see their yield decrease.
  • the cover has ribs for separating the pulleys actuators. These separation ribs achieve a internal partition of the cover and allow to define the path of the arches being wound on the pulleys in to ensure that no interference occurs between arches or between arches and neighboring pulleys, including in the event of an arch rupture.
  • the housing includes a guide bar provided with orifices for passage of the arches controlled by the actuators. This function is to define the positioning of the arches in relation to the pulleys to ensure winding and an optimal course, whatever their orientation subsequent, in particular due to the position of the board drip.
  • the compartments are each provided with a bottom screen pierced with a hole for power supply to actuators arranged in the compartments by their side opposite the pulley they carry. This allows the actuators to be powered without interference with the pulleys and the arches they carry.
  • this veil bottom includes a bearing surface for a leg integral locking of the actuator arranged in the compartment corresponding. The cooperation of the reach surface and locking tab keeps it in position efficient actuator inside the compartment.
  • the housing includes means for positioning relative to a electronic device for controlling the actuators arranged in the compartments, this electronic device comprising means of electrical supply and / or means of detection of the angular position of the actuators.
  • the box can be connected to an electronic control device by a simple operation and, in particular, by clipping. This guarantees a satisfactory positioning of the actuators with respect to their respective control devices.
  • the invention also relates to a weaving loom equipped an armor mechanic that includes one or more cases as previously described. This job is easier to implement and maintain that art devices anterior and allows wire-to-wire control of a harness Jacquard loom. Its performance is therefore significantly improved compared to the known technique.
  • the housing 1 shown in Figure 1 comprises sixteen compartments 2, arranged in four rows and four columns.
  • the compartments 2 are separated by partitions internal the housing 1 which extend in two directions generally perpendicular, so that the compartments 2 are of substantially parallelepipedal section.
  • Each compartment 2 has a substantially equivalent internal section to the external section of an electric rotary actuator 3 which it is intended to receive.
  • Each actuator 3 is equipped with a pulley 4 for the controlled winding of a yoke 5.
  • Actuator 3 can be pushed into the corresponding housing 2 in a direction F substantially parallel to the axis of rotation XX 'of the pulley 4.
  • the actuator 3 On its rear part, that is to say opposite the pulley 4, the actuator 3 carries a extension 6 provided with pins 7 for its electrical connection with an electronic control device carried by a card with printed circuit 8.
  • the bottom panel 9 of each compartment 2 is pierced with an orifice 10 for the passage of the extension 6 and pins 7.
  • the rear edge of the housing 1 is provided with a first rebate 1 c for receiving and jamming the card 8.
  • a second rebate 1 d is also provided for receiving a second 8 'electronic control card.
  • the actuator 3 also carries on its face opposite to the pulley 4 a cup 11 secured to the rotor, not shown, on which the pulley is mounted 4.
  • the cup 11 is provided with notches 11 a on its external radial surface.
  • a clamping or braking force can be applied to the cup 11 substantially perpendicular to the axis of rotation XX ′ of the pulley 4. This force can be applied by any suitable means while the notches 11 a allow blocking of the cup 11 in position.
  • the cup 11 is cut out with teeth defining slots therebetween. The succession of these teeth and these slots allows a detector 12 of the optical, infrared or equivalent type, to identify the orientation of the cup 11 and of the pulley 4 around the axis XX '.
  • the detector is advantageously carried by the card 8.
  • each actuator controls the movement of an arch thanks to the pulley 4 present on its front face turned to the left of figure 2, while it is being ordered thanks to pins 7 and the cup 11 located on its face rear facing right in Figure 2.
  • a cover 15 is intended to cover the sixteen pulleys of the actuators 3 arranged in the sixteen compartments 2 of the housing 1. This cover prevents the accumulation of fluff or the contact of an operator's tool with pulleys in movement.
  • the cover 15 is provided with primary internal ribs 15 a which extend in the direction of the dividing partitions 1 a from the housing 1. As it appears in particular in FIGS. 1 and 3, the ribs 15 a extend in a first direction generally perpendicular to the axis XX ′ of the pulleys 4 in which they are contained, while they carry secondary ribs 15 b , also internal, arranged substantially perpendicular to the primary ribs 15 a .
  • the set of ribs 15 a and 15 b makes it possible to separate the pulleys 4 from the different actuators 3 from one another, which avoids the flow of flock between the different pulleys.
  • the ribs 15 b do not interconnect the ribs 15 a , because they are truncated so as to leave a passage for one or more arches 5 between their free end and the neighboring primary rib 15 a . It appears in particular in Figure 3 that the secondary ribs 15 b have different lengths, the ribs being shorter and shorter when the number of arches for which they must leave a passage increases.
  • the ribs 15 b have the role of preventing an arcade integral with a pulley of an upper actuator from coming into contact with a pulley of a lower actuator, in particular in the event of a breakdown, when a system of elastic reminder pulls the arch down.
  • the ribs 15 a are oblique with respect to the columns formed by the compartments 2.
  • the oblique nature of the ribs 15 a is intended to allow the passage of the arches 5 generally parallel in the direction of a guide bar 16 disposed in the lower part of the housing 1.
  • an arcade provided for winding on a pulley 4 above would interfere with the or the pulley (s) arranged below it in FIG. 3.
  • the oblique positioning of the arches 5 therefore makes it possible to eliminate the risks of interference between the arches and the pulleys.
  • the openings 16a are generally in the plane of the first turn formed by the arches 5 being wound on the pulleys 4 in a column of actuators. This makes it possible to limit the friction on arches 5 at the level of the orifices 16 a and of the strand of the arches during winding on the strand of the arches already wound.
  • the orifices 16 a are staggered, that is to say alternately on two lines D and D 'perpendicular to the axis XX' of rotation of the pulleys 4.
  • the cover 15 also includes housings 15 c for receiving the anterior ends of the pulleys 4 in the position shown in FIG. 2. These housings exactly define the relative positioning of the different pulleys, so that the cover 15 cannot be put in place. if one of the actuators 3 is not correctly installed in the corresponding compartment.
  • the cover 15 is mounted on the housing 1 by means of screws represented by their center lines 15 d and intended to penetrate tapped holes 1 b of the housing 1.
  • the actuator 3 is provided with two oblique slots 3a defining corners 3B movable relative to the rest of the actuator 3 by the elasticity of the material constituting them. These movable corners are pushed in the direction of the axis of rotation of the pulley 4 of each actuator when it is introduced into the corresponding compartment. They contribute to friction blocking of the actuator in its compartment.
  • Each actuator 3 is provided with a resilient tab 17, visible in Figures 4 and 5, whose end is equipped with a nose or spout 17 is designed to be stuck on a support surface 9a of the web 9.
  • the elastic tab 17 is slightly deformed when its beak 17 has passed through the orifice 10. Then and as it appears in FIG. 5, beak 17a bears against the surface 9a, so that the actuator 3 is held firmly in position.
  • the housing 1 as a whole, possibly integral with the plate 8, can be dismantled relative to the rest of the armor mechanics. It can then be carried out standard exchange of the housing.
  • case 1 may not be completely furnished. If necessary, it can easily be supplemented at any time with additional actuators.
  • the housing 51 of this embodiment comprises a single compartment 52 capable of receiving four actuators 53 shown in phantom.
  • the locations of the actuators 53 in the compartment 52 are defined by ribs 71 extending generally parallel to the sides of the housing 51 over part of the height ( h ) and the width ( 1 ) of the compartment 52.
  • the ribs 71 therefore allow a relative positioning of the actuators 53 inside the compartment 52.
  • the housing 101 includes a single compartment 102 in which can be received nine actuators 103 shown in phantom.
  • Centering pins 122 are provided in compartment 102 in order to define the positions of the actuators 103 in the compartment 102.
  • the pawns 122 have been represented with a generally circular section. They could however have a cross-shaped section so as to present angles for receiving the corners of the actuators 103.
  • the housing 151 comprises a single compartment 152 in which three actuators 153, 153 'and 153 "can be received, shown in phantom.
  • the actuators 153 and 153' are simple, that is to say they are used to control a single arch.
  • 'actuator 153 is double, that is to say allows to control two arches, which is shown in phantom by the traces of two pulleys.
  • the relative positioning of the actuators 153, 153 'and 153 "inside the compartment 152 is obtained by the fact that the section of the compartment 152 corresponds relatively precisely to the sum of the external sections of the actuators 153, 153' and 153".
  • the outer walls 151 a , 151 b , 151 c and 151 d of the housing 151 are the only means for positioning the actuators 153, 153 'and 153 "inside the compartment 152.
  • boxes of the second, third and fourth embodiments can also be fitted a cover as described with reference to the first mode of realization and, more generally, of all the improvements of the first embodiment which can be transposed to them.
  • the housing according to the invention allows precise positioning of the actuators in space, their tightness thanks to its cover, their cooling by dissipation of energy, their electrical connection to an electronic power supply board and control, the support of an electronic power supply card and control, the support of their braking and security, guiding the arches and fixing it as that together on a support system such as, for example, a rail-shaped profile.
  • the case has a depth corresponding to only part of the length of actuators 3, that is to say of their dimension parallel to axis XX ', so that once installed in the housing, the actuators protrude from the back of it.
  • a cover of generally parallelepiped shape and without internal ribs could be installed on the back of the case so as to cover the rear parts actuators. Electrical connection means could be provided at the bottom of this cover.
  • the positioning in the space of the actuators would be realized by the ribs or the housing pins located between the actuators on their anterior part.
  • the housing is provided with skirts extending parallel to the XX 'axis of the actuators so as to protect the electronic cards to which it is connected against traffic of the flock that is found in large quantities in the working environment of the actuators.
  • the boxes of the invention have been shown as receiving rotary electric actuators. Of course, these boxes allow the positioning of all types of actuators electric and, in particular, linear actuators.
  • the housing is advantageously made in a metariau good conductor thermal, especially metal such as aluminum or Zamak (registered trademark). This facilitates the cooling of actuators which tend to overheat due to the electrical power they consume.
  • the invention is also applicable to textile machines in general and, in particular, knitting machines for controlling needles.
