Definitions

  • the present invention relates to dobbies and other mechanical armor of the rotary type for crowd formation on weaving machines.
  • the tack mechanics include a number of oscillating actuators which are pivotally mounted on a common fixed axis and which are connected to the usual healds of the weaving machine by a pulling system incorporating return levers and transmission rods, which levers pivot themselves on fixed axes carried by the supporting frame the usual housing of the mechanics considered.
  • Patent Application EP-A-0 740 003 which represents the only relevant prior art and which falls under Article 54 (3) EPC, we have described a support frame for armor mechanics comprising a U-shaped cross-section piece open towards the high, the longitudinal wings of which are arranged to support the pivot axes of the levers of the pulling system which ensures the vertical control of the heald frames of the weaving machine.
  • the mechanics are fixed against a box attached to one of the ends of this support frame.
  • the present invention is based on the fact that, by means of an arrangement suitable, such a support frame can advantageously take the place of the casing usual armor mechanics.
  • the armor mechanics of the rotary type according to the invention is defined at claim 1.
  • the invention essentially consists in making one of the ends of the U-shaped part which forms the support frame two raised side cheeks which are drilled to support the drive shaft and the common pivot axis of the oscillating actuators mechanics, and to seal this part tightly so that it can contain the usual oil bath intended for lubrication moving parts of the mechanics and the associated draft system to it, and this by means of an incorporated lubrication system.
  • the U-shaped part is advantageously closed towards the top by a cover which avoids the fallout of textile stuffing in the oil bath, which cover is cut out with suitable lights for the passage of vertical connecting rods intended for maneuvering heald frames. It is against this cover that are fixed
  • Fig. 1 is a perspective view illustrating the general arrangement armor mechanics according to the invention.
  • Fig. 2 is a longitudinal section of the mechanics according to FIG. 1, after assembly of the elements assumed to be dismantled in fig. 1.
  • Fig. 3 is a longitudinal section exposing more precisely the mechanical lubrication system in the case of a dobby rotary type eccentric and connecting rods.
  • Fig. 4 recalls the arrangement of the usual mechanical pull-by below.
  • Fig. 5 illustrates the application of the invention to rotary mechanics with cams.
  • Reference 1 designates the part which simultaneously constitutes the support frame and the armor housing.
  • This part 1 has a U-shaped cross section open towards the top, which is defined by a flat bottom 2, two longitudinal wings 3 and two transverse partitions with ends 4, it being observed that the latter ensure a perfectly sealed closure so that said part 1 thus arranged can contain without leaking a quantity of oil, referenced 5 in fig. 2.
  • the two levers 16 associated with the same frame 18 are coupled one to the other by a horizontal rod 19, one of said levers being in further coupled by an oblique rod 20 to one of the oscillating members 14, so that the alternating angular displacement of this member ensures the vertical displacement of the frame 18 to which it is coupled.
  • a cover 21 which covers the part of the part 1 arranged below the frames 18 and which is cut out of two transverse lights for the passage of the two series of vertical rods 17.
  • This cover 21 is extended by a removable cover 22 which protects the oscillating members 14, actuating rods 12 and the reading device 23 which operates the programmed control of said connecting rods 12.
  • Fig. 3 illustrates well the mounting of a rotary dobby according to the invention whose support frame is securely attached to the two vertical structures 24 of a conventional weaving machine.
  • This dobby is equipped with a lubrication system which includes a pump 25 for feeding a series of transverse lubrication ramps 26 arranged above the pivot axes 15 of the deflection levers 16, above of the axis 13 on which the oscillating members 14 pivot, above of the shaft 11 and above the connecting points of the connecting rods 19 and 20 and links 17.
  • the invention is applicable to armor mechanics at cams like the one illustrated in fig. 5, in which the command oscillating members 14 coupled to the oblique connecting rods 20 is operated at using additional cams 27 which are wedged on the motor shaft 11 to act on rollers 28 carried by said members 14.
