Definitions

  • the present invention relates to machines for centrifuging coils, in particular wire, at the outlet of wet treatments such as dyeing, and it relates to a manipulator arranged so as to ensure fully automatic loading and unloading of the rotating basket from one or more centrifuge machines.
  • Such a manipulator has been described in document FR-A 2 549 867 which relates to a machine with multiple stations for spinning textile rolls.
  • a manipulator which is clean on the one hand to have, on a movable plate enclosed by the usual rotating basket, each of the coils to be wrung successively brought to the wringer considered, on the other hand to evacuate of said plate each coil after spinning.
  • the manipulator described comprises a drawer arranged in the manner of a carriage driven by an alternating horizontal movement which makes it pass from a retracted position to an advanced position; in the retracted position, the drawer, moved forward, takes a spool from the base of a stack, to push it along a fixed table which is flush with the upper outlet of the wringer tank considered , and bring it on the movable plate which can be lowered to effect the loading of said tank.
  • this tray rises to bring back to the table height the spun spool which when advancing the drawer or carriage will be pushed back by the next spool to be spun and be expelled by sliding along an appropriate corridor and reception on an evacuation conveyor.
  • the manipulator according to the invention is defined in claim 1. It is constituted, in known manner, by a carriage which is driven, for example under the action of a double-acting cylinder, of an alternating horizontal movement which brings it from a withdrawn withdrawal position to an advanced position situated above the opening of the rotating basket of the envisaged centrifugation machine.
  • this carriage is provided with a handling mechanism comprising on the one hand two adjustable wings capable of forming stops for the successive coils to be wrung, on the other hand two movable arms suitable for opening to allow the application of each coil against the aforementioned wings, and to close against said coil in order to make it integral with the carriage.
  • the latter further comprises an articulated flap associated with an actuating member intended to pass it from a horizontal orientation for which it closes the upper opening of the centrifugation machine, to a vertical position for which it forms a pusher for the evacuation of the coil extracted from the rotating basket of said machine.
  • reference 1 designates the general frame of the installation formed by the centrifuge machine 2 and the manipulator 3 which ensures its automatic feeding.
  • the machine 2 comprises a fixed tank 4 inside which a basket 5 rotates driven by an electric motor 6 carried by a base 7 of frame 1; the shaft 8 of this motor 6 is provided hollow so as to leave room for an axial pusher 9 provided with a lifting plate 10 which slides freely in the basket 5 under the effect of an actuating member, assumed to be flexible in the embodiment envisaged and guided for this purpose inside a bend 11, this member, rigid or flexible, being controlled alternately by a pneumatic cylinder 12 of the double-acting type.
  • the manipulator 3 comprises a carriage 13 provided at its base with pads which allow its movement on horizontal guides 14 of the frame 1.
  • the reciprocating movement of the carriage 13 is effected by means of a double-acting pneumatic cylinder 15, the cylinder is fixed to the frame 1 while the movable member is made integral with said carriage by means of a vertical arm 16.
  • the carriage 13 is formed by two lateral flanges referenced 13a in FIG. 2, joined to each other by a front cross member 13b and an upper cross member 13c, so that said carriage is open downward and backward thereby allowing coils such as A (fig. 1 ), brought in succession by a conveyor belt 17, to penetrate from the rear inside this carriage.
  • This is equipped with a handling mechanism which first includes two trans axes side 18 (fig. 2) which are slidably carried by the flanges 13_a so as to be able to be adjusted in axial position using a toothed device 19 which ensures the simultaneous movement of said axes in opposite directions; this device 19 may in particular be constituted by a central pinion capable of being operated angularly using a crank or similar tool, which pinion meshes with rack and pinion teeth formed on the protruding ends of the axes 18.
  • Each of these ci is secured to a transverse wing 20 profiled so as to embrace the cylindrical wall of a coil 1, in the manner which will be described later, and it is understood that the adjustment of the axes 18 makes it possible to modify the mutual spacing wings 20 and the adaptation thereof to the diameter of the coils to be wrung.
  • the handling mechanism also includes two transverse rods 21 associated with two independent cylinders 22 which ensure their axial sliding in one direction or the other.
  • Each rod 21 carries a transverse arm 23 able, by sliding one and the other of said rods in opposite directions, to come to bear against the wall of a coil A supposed brought into abutment against the wings 20, as we will describe it later.
  • a tilting flap 24 coupled to an actuating cylinder 25 of the double-acting type.
  • This flap 24 is thus likely to affect either the position raised vertically illustrated in FIG. 1, that is to say the horizontal folded position for which it closes the upper opening of the opening made in the fixed table 26 which surrounds the rotating basket 5.
  • the first coil A to be wrung brought by the belt 17 is applied against the wings 20 previously adjusted in position.
  • a probe determines the arrival of this coil A and actuates the jacks 22, so that the arms 23 come to grip the coil A which is then made integral with the carriage 13.
  • the jack 15 comes into action to push the carriage 13 to the advanced position illustrated in fig. 3, for which the axis of the upper jack 27 coincides with the axis of the rotating basket 5.
  • the plate 10 associated with this basket 5 is in the high position, so that the coil A clamped between the arms 23 and the wings 20 of the handling mechanism is transferred to said plate 10 by simple operation cylinders 22 at the spacing.
  • the jack 12 is then controlled by contraction in order to ensure the lowering of the plate 10 inside the basket 5.
  • This lowering movement is advantageously facilitated by actuation of the vertical jack 27 whose movable pusher 28 comes to bear against the upper part of the coil A which is thus forced into the basket 5 at the same time as the plate 10 (position of fig. 4).
  • the jack 27 rises the pusher 28 and the carriage 13 is returned by the jack 15 to the retracted starting position.
  • the jack 25 then lowers the flap 24 which, by pressing against the table 26, seals the open upper part of the tank 4, in the manner illustrated in FIG. 5. Spinning of coil A can then take place by energizing motor 6.
  • the tilting flap 24 is raised vertically (fig. 6) at the same time as the jack 12 rises the plate 10 with the spool A spun.
  • the jack 15 moves the carriage 13 from the retracted position according to FIG. 6 in the advanced position according to fig. 7, so that the flap 24 in the raised position acts in the manner of a pusher to drive out of the plate 10 the spool A spun.
  • This coil A is collected on a front plate 29 placed at the level of the table 26 and associated with any suitable evacuation device.
  • the spin cycle of the coil A is then ended, but in the meantime, that is to say when the carriage 13 was in the retracted position according to FIG. 5, a new coil to be wrung out, referenced A ′, was brought from behind by the belt 17 and came to be disposed against the wings 20.
  • the arms 23 were tightened on this coil A ′ which was transferred to the movable plate 10 when the carriage 13 has passed from the retracted position of FIG. 6 in the advanced position according to fig. 7.
  • the wringing cycles succeed one another in this way and it suffices finally to supply the conveyor belt 17 with coils to be wrung and the evacuation of the coils wrung from the plate 29.
  • this plate 29 was arranged at the height of the table 26 so as to receive the coils in the vertical position.
  • the latter can be arranged at a lower level so that the spun coils tilt when they are pushed back by the flap 24.
  • FIG. 8 illustrates such a variant and clearly highlights the fact that the coils are collected on the plate 29 in the lying position.
  • the carriage 13 is made to include a thrust frame 31 (FIGS. 1 and 2) disposed at the front of said carriage and assembled to the latter in an articulated manner so as to be able to be maneuvered angularly using '' a cylinder such as 32.
  • a thrust frame 31 (FIGS. 1 and 2) disposed at the front of said carriage and assembled to the latter in an articulated manner so as to be able to be maneuvered angularly using '' a cylinder such as 32.
  • Fig. 1 shows that the adjustment of the receiving plate 29 is effected by means of two separate jacks 30, so as to make it possible to give said plate an appropriate inclination when the coils to be treated do not have a cylindrical profile as has been assumed up to 'here, but a tapered profile. This avoids any untimely sliding of the coils on the plate.
  • the invention lends itself particularly well to the production of installations with multiple extractors, of the kind of that illustrated in FIG. 9 where it was assumed that the assembly included four centrifugation machines, arranged along the same axis oriented transversely to the axis of movement of the carriage 13 of the manipulator 3.
  • This carriage 13 is obviously established at a suitable width; its handling mechanism comprises, on the axes 18 and on the rods 21, four pairs of stop wings 20 and four pairs of arms 23 in order to grip the four coils to be wrung simultaneously brought by the conveyor belt 17.
  • the manipulator according to fig. 8 is equipped with a thrust frame 31 maneuvered by two lateral jacks 32 and it has been assumed here that the spun coils collected in the lying state on the receiving plate 29 were engaged by the cross member 31a on support rods 34 oriented horizontally above said tray. It goes without saying that the plate 29 can be profiled to receive each row of coils, in particular by including gutters in number equal to that of the centrifugation machines.
