Definitions

  • the present invention relates to a machine for tying spools of metal wire, manufactured in particular in metallurgical factories.
  • Tying devices are known in which clamps can be moved parallel to the axis of the coil, outside and inside thereof, so as to form a loop around the coil with a wire. tying, the two ends of this loop then being twisted.
  • This carriage is movable in translation parallel to the axis of the coil, and means are provided for passing one arm externally to the coil, and the other arm internally to this coil.
  • This arrangement makes it possible to pass the link on the internal face and on the external face of the wall of the coil.
  • tie arms are satisfactory in most cases. However, these arms risk being damaged when the coil is irregular (which is often the case), poorly positioned opposite these ligating arms, or when this coil comprises wires protruding into the inner cylindrical space of the coil.
  • the twisting means of this machine comprise a mandrel movable in translation and in rotation, and comprising a head arranged to receive the two ends of the link, as well as a counterplate disposed opposite the head of the mandrel to maintain the link during rotation of the mandrel.
  • This twisting device makes it possible to tighten the link between the mandrel and the counter plate, the latter remaining fixed during the twisting.
  • this twisting device does not allow very effective tightening of the links against the wall of the coil.
  • the object of the invention is to remedy the drawbacks of known devices, by creating a relatively simple construction machine which allows the coiling of coils of metal wire in a rapid and secure manner.
  • this machine comprising means for placing links around the coil, and means for twisting the free ends of these links, is characterized in that it comprises a substantially planar support comprising a recess, a guide- link defining a closed path extending around this recess, means for moving the support towards the coil in order to engage the wall of this coil in the aforementioned recess of the support, means for fixing one end of the link at a point located between the bottom of the support recess and the adjacent end of the wall of the spool, in that the link guide comprises means for hooking the link at a point located near the above-mentioned fixed point and means for cause this point of attachment of the link along the closed path of the link guide, and in that means are provided for cutting this link at a point situated between the wall of the coil and the aforementioned attachment point of the link.
  • the link is driven by the link guide, along the path which extends all around the wall of the coil.
  • the attachment point of the link returns to its initial position, so that this link forms a loop around the wall of the coil. It then suffices to cut this link downstream from its point of attachment to the link guide, then to twist the two free ends of the link against the adjacent end of the wall of the coil.
  • the aforementioned support and its link guide are not likely to be damaged during the translation of the recess of this support relative to the wall of the coil.
  • the link guide defines a circular path around the wall of the coil.
  • Such. circular route can be achieved using simple means.
  • the means for hooking and driving the link along the aforementioned circular path comprise a ring mounted in rotation about an axis perpendicular to the support, this ring having an opening which is located opposite the 'entry of the recess, when this ring is in the rest position, and this ring carries at least one roller for the attachment of the link.
  • the opening of this ring allows the engagement of the wall of the coil in the recess of the support.
  • This ring preferably carries several rollers which make it possible to guide the link upstream from its point of attachment to the ring, along the circular path determined by the ring.
  • the machine according to the invention comprises means for rotating the coil engaged in the recess of the support.
  • the machine comprises two substantially planar supports each comprising a link guide, these supports being arranged substantially in a diametral plane of the coil.
  • the machine according to the invention also comprises means for cutting the ends of the link and for twisting these ends against the wall of the coil.
  • the means for cutting the link are carried, preferably, by a rotary mandrel whose twisting end has a diametrical groove adapted to receive the ends of the link.
  • This diametral groove is used to twist these ends of the wire.
  • the twisting means further comprise two plates arranged on either side of the axis of the mandrel, and movable towards this axis, in a plane situated between the twisting end of the mandrel and the wall of the coil, this plane passing substantially through the crossing point of the ends of the link.
  • the machine for binding spools of metal wire advantageously comprises, in combination, means for compacting the spool before it is tied up.
  • These compacting means comprise two pressing plates movable axially towards the coil.
  • these two pressing plates comprise means for advancing them towards the opposite ends of the coil at identical speeds and symmetrically with respect to this coil.
  • the machine according to the invention is a compactor-ligator, that is to say that it comprises, in combination, means for compacting coils of metal wire, and means for laying ties around these coils.
  • the coil 1 of metallic wire for example of iron wire
  • the hook 2 of a conveyor (not shown), between the space 3 comprised between two vertical pressure plates 4 and 5, mounted on carriages movable in translation by rollers 4a and 5a.
  • the coil 1 Before compaction, the coil 1 has a longitudinal trapezoidal section (non-hatched part of the coil shown in Figure 1) because the turns of this coil are relatively loose.
  • the pressing plates 4 and 5 are associated with means making it possible to advance them at identical speeds and symmetrically with respect to the coil 1.
  • these means comprise two identical hydraulic cylinders 6 and 7, fixed to the frame 8 of the machine.
  • the rods 9 and 10 of these jacks 6 and 7 are made integral respectively with the pressure plates 4 and 5.
  • the pistons 11 and 12 are offset longitudinally relative to their respective chambers 13, 14, so that when the rod 9 or 10 of one of the jacks 6 or 7 is in the retracted position, the rod 9 or 10 of the other cylinder is in the released position.
  • the displacement of the pistons 11 and 12 is carried out in opposite direction, one with respect to the other, by volume transfer from hydraulic fluid 16 contained in one of the chambers 13 or 14 of the jacks 6 or 7 towards the other chamber 13 or 14 of these jacks.
  • the compactor according to the invention thus makes it possible to significantly increase the production rate of the compacted coils, without additional energy consumption.
  • the compactor according to the invention also makes it possible to obtain perfect regularity in the compaction of the coils 1, which is likely to considerably facilitate the subsequent ligating operations.
  • the compactor according to the invention also has the advantage of allowing the compaction of the reel 1, without it being necessary to remove the reel 1 from the hook 2. In fact, during this compaction, this hook 2 can engage in recesses 4b and 5b formed behind the pressure plates 4 and 5 (see Figure 2).
  • the machine according to the invention further comprises means for compacting the coil 1 in two stages of successive compression, separated by a step of decompression of the coil 1.
  • the coils are compacted under a pressure corresponding to a thrust of 30 to 50 tonnes exerted by the pressing plates 4 and 5, then these coils 1 are decompressed to obtain an extension of their length by approximately 10% .
  • the coils 1 are then again compacted at the aforementioned compacting pressure.
  • the fully compacted coil is shown in Figure 1 by the hatched portion 1a.
  • these means for placing links around the coil 1 firstly comprise a plane support 20 movable in translation relative to the coil 1. In the inactive position, this plane support 20 is housed at the rear of the pressure plate 4, as shown in Figure 1.
  • this planar support 20 The translation of this planar support 20 towards the coil 1 and towards the pressure plate 5 is controlled by a hydraulic cylinder 21 fixed to the frame 8 of the machinc. In the example shown, this planar support 20 can be moved in a horizontal plane passing substantially through the axis of the coil 1.
  • the planar support 20 comprises two link guides 22, 23, identical, defining circular paths.
  • link guides 22, 23 extend around two recesses 24, 25, substantially rectangular, parallel between them, with the axis of the coil 1 and with the direction of movement of the plane support 20.
  • each link guide 22 or 23 comprises a series of rollers 27 regularly distributed around the circular path defined by the link guide 22 or 23. These rollers 27 are fixed on a split ring 28, the slot defining an opening 29 which is located opposite the entrance to the recess 24 of the support 20, when the link guide 22 is in the inactive position.
  • This split ring 28 is relatively thin and it rests on the support 20.
  • the machine further comprises means for fixing the link 36 at a point A situated between the bottom 24a of the recess 24 and the adjacent end 26a of the wall 26 of the coil 1.
  • this fixed point A is located behind the axis XX 'relative to the direction of rotation of the ring 28 (see arrow F in Figure 5).
  • This fixed point A can be obtained by a clamp 37 (see Figure 9), maintaining the end A of the link 36.
  • the link guide 22 also includes means for hooking the link 36 at a point B, located opposite the fixed point A, relative to the axis XX '.
  • these coupling means are constituted by the roller 27a, the link 36 being wound partially around 0 this roller 27a.
  • the link 36 is stretched between the fixed point A, around the roller 27a and around three pulleys 38, by means of a tensioner 39.
  • This tensioner 39 comprises a fixed disc 40 and a wheel 41 rotatably mounted about an axis YY 'centered on the disc 40.
  • the link 36 is wound in a clockwise direction around this pulley 40, then is wound in a loop in opposite directions on a series of rollers 42 arranged on the periphery of the wheel 41.
  • the tension exerted on the 3G link, between the tensioner 39 and the fixed point A, is produced by means of a spiral spring or the like (not shown), inserted between the disc 40 and the wheel 41.
  • the support 20 comprises two recesses 24 and 25, and two link guides 22 and 23, juxtaposed, allowing two links 36 to be placed simultaneously around the wall 26 of the coil 1.
  • the link guides 22 and 23 are situated in planes slightly offset with respect to the axis ZZ ′, so as to allow a partial superimposition of the link guides 22 and 23, and therefore reduce the overall dimensions of the support 20.
  • the coil 1 rests on rollers 43 which can be rotated by a system of pulleys or pinions and an electric motor (not shown).
  • This arrangement allows the coil 1 to turn on even, according to predetermined angular rotations in order to be able to place several pairs of links 36 around the wall 26 of the coil 1, without moving the support 20.
  • rollers 43 are carried by arms 4 4 pivotally mounted on axes 45, 46, so as to allow to properly adjust the position of the coil 1 by ra p port to the recesses 24 and 25 of support 20.
  • the support 20 is then moved towards the coil 1 so that the wall 26 of this coil is completely engaged in the recesses 24 and 25 of the support 20 .
  • the ring 28 is subjected to a complete rotation around its center O, in the direction of the arrow F (see FIG. 5).
  • the portion 36a of the link 36 between the attachment roller 27a and the pulley 38 is wound around the rollers 27 preceding the roller 27a. These rollers 27 thus guide the link 36 along the circular path defined by the ring 28.
  • This mandrel 50 is aligned substantially in the axis XX ′ of the section of the wall 26 of the coil 1, which is surrounded by the link 36, and with the crossing point D of the ends 36c and 36d of the link 36.
  • This rotary mandrel laterally carries an arm 51 comprising a knife 52 which can come into contact with the part 36c of the link 36, during the rotation of this mandrel 50.
  • a fixed knife 53 serves as a support for the portion 36c of the link 36, when the knife 52 is supported on the latter.
  • the mandrel 50 comprises, at its end 50a, adjacent to the end 26a of the wall 26 of the coil, one or more diametric grooves 54 capable of receiving these ends 36c and 36d of the link 36, when the mandrel 50 is moved towards the crossing point D of its ends 36c and 36d of the link 36.
  • the twisting device further comprises two plates 55, disposed on either side of the axis XX 'of rotation of the mandrel 50, and movable towards this axis in a plane located between the head 50a of the mandrel 50, and the wall 26 of the coil 1. This plane also passes through the crossing point D of the ends 36c and 36d of the link 36.
  • the different operating sequences of the machine namely the correct positioning of the coil 1 by means of the pivoting arms 44 carrying the rollers 43, the translation of the support 20 by means of the jack 21, the rotation of the rings 28 of the guides -links 22 and 23, the movement of the clamp 37 towards the fixed point A, the successive rotations of the coil 1, can be controlled in a fully automatic manner, by known means.
  • the link 36 is not likely to seize, or to break, or to be damaged during its travel on the link guides 22 and 23, given that the link 36 describes a circular route devoid of sharp angles, and that this link 36 undergoes practically no friction on the rollers 27.
  • the cutting and twisting device 50 included the cutting arm 51 and the movable plates 55, makes it possible to perform tight twists, properly applied against the wall 26 of the coil 1.
  • the links thus produced therefore do not risk slackening, which is likely to cause considerable difficulties during the transport of the coils 1.
  • the link guides 22 and 23 could define a closed non-circular route, provided that the mode of travel is adapted to the shape of such a route. cementing the roller 27 or other attachment or guiding system for the link 36.
  • the support 20 carrying the link guides 22 and 23 could be rotated about the axis of the coil 1, in order to be able to place several links 36, angularly spaced around this coil, without having to rotate this coil.
