Definitions

  • a binding machine comprising in particular a substantially flat support comprising at least one substantially U-shaped recess, a link guide defining a closed path extending around this recess, means for moving the support towards the coil in order to engage the wall of the coil in the recess of this support and means for fixing one end of the link at a location adjacent to the wall of the coil.
  • the link guide comprises means for hooking the link at a point located close to the aforementioned location and means for driving this point of attachment of the link along the closed path defined by the link guide and it is provided means for cutting the link at a point between the wall of the coil and the attachment point.
  • the link guide of this machine defines a circular path around the wall of the coil.
  • this machine can comprise two supports, as described, which are offset perpendicular to the diametral plane of the coil, so that it is possible to carry out at the same time two ligaturages.
  • the machine is provided with means capable of driving the engaged coil in rotation, thus making it possible to carry out several successive single or double ligaturations, by interposing rotations of the coil around an adequate angle.
  • means capable of driving the engaged coil in rotation thus making it possible to carry out several successive single or double ligaturations, by interposing rotations of the coil around an adequate angle.
  • means are provided allowing to hang the tying link, to cut it and to twist its ends.
  • the means for cutting the link are secured to a rotary mandrel whose end has a groove which can receive the ends of the link held by the attachment means.
  • the machine also includes means for compacting the spool before tying; these means being constituted by 2 mobile presser plates, provided with 2 identical hydraulic cylinders whose pistons are offset longitudinally so that when the rod of one of the pistons is in the retracted position, the rod of the other piston is in clear position.
  • the ends adjacent to the piston rod of the chambers of the cylinders communicate with each other by a tube, so as to allow the displacement of the pistons of the two cylinders by reciprocal transfer of volume of hydraulic fluid from one of the cylinders to the other.
  • the link guide defining a closed path extending around the recess in the plate supporting the ligating means moves along a path formed by at minus an oblong guide element.
  • the plate includes a link guide which defines a closed path around a recess in this plate intended to receive the body of the coil in one of the binding areas.
  • the recess can be chosen deep enough to receive large coils, without the tray dimensions becoming prohibitive for this.
  • the link guide is constituted by an articulated chain composed of identical links.
  • Each link has a guide assembly comprising a common axis, which carries a link guide pulley and two rollers.
  • the link guide according to the invention constitutes a drive means which makes it possible to drive any object, in this case the link, along a closed path which is oblong in the preferred embodiment, but which could take any form, as needed.
  • the installation according to the invention also comprises, in each tie-up plate, a fixing assembly, composed of a link hanger, which maintains one end of the link along the outer wall of the coil, while the latter this is guided and pressed under tension around the body of the coil (unlike other known machines where the wire is laid by retrotraction and where it slides on the end turns of the coil and risks damaging them), a cut - link, as well as a welder which completes the fixing operation on the two ends of the link held against each other at a location along the outer wall of the coil.
  • a fixing assembly composed of a link hanger, which maintains one end of the link along the outer wall of the coil, while the latter this is guided and pressed under tension around the body of the coil (unlike other known machines where the wire is laid by retrotraction and where it slides on the end turns of the coil and risks damaging them), a cut - link, as well as a welder which completes the fixing operation on the two ends of the link held against each other at a location along the outer wall of
  • the welder leans, in this variant against the protective plate placed against the wall of the coil at a constant distance whatever the outside diameter of the coil. It makes it possible to affix the two ends of the link by longitudinal overlap parallel to one another under high pressure, to cut using a shear mounted on the welder one end of the link, so that the guide- link can return to its starting position, open the clamp and release the other end of the link and make several welding points simultaneously.
  • the lengths and the tension of all the links of the coil are identical regardless of the dimensions, the configuration and the possibly non-concentric position of the coil in the machine.
  • the machine shown in the figures is a compactor-ligator-welder, i.e. that it carries in combination means for compacting coils of metal wire, means for passing links around these coils and means for welding the ends of these links by overlap.
  • the compacting operation being known (see French patent 79.04535), we will limit our to describing the laying of the links and the welding.
  • the coil 1 of wire for example of wire, is brought, carried by the hook 2 of a conveyor (not shown) in the space 3 comprised between two vertical pressure plates 4 and 5, mounted on carriages movable in translation thanks to rollers 4a and 5a.
  • the latter is raised by means of a support 6 movable in vertical direction (see fig. 3) to release the coil of the laying surface 7 of the hook 2. This prevents the turns from being damaged during compaction.
  • the vertical movement of this support 6 is controlled through a system of levers by a jack fixed in the horizontal position. zontale to chassis 9 of the compactor-ligator.
  • the compactor according to the invention also has the advantage of allowing the compaction of the spool 1, without it being necessary to remove the spool from the hook 2.
  • the hook 2 can engage in recesses 4b and 5b arranged in the pressure plates 4 and 5 (see fig. 2).
  • the means for placing links around the coil 1 first of all comprise a support 10 comprising four plates 11, the planes of which pass through the axis of the coil 1 or are parallel to it . Two adjacent plates 11 are approximately perpendicular.
  • the support 10 is movable in translation relative to the coil 1 and in the inactive position there. is housed at the rear of the pressure plate 5 as shown in fig. 1.
  • the translation of this support 10 towards the coil 1 and towards the pressure plate 4 is controlled by a hydraulic cylinder 12 fixed to the rear of the mobile carriage carrying the pressure plate 5 (see fig. 1 and 2).
  • Each plate 11 includes a link guide 13, which defines an oblong path.
  • This link guide 13 extends around a U-shaped recess 14 parallel to the axis of the coil 1 and to the direction of movement of the plate 11.
  • This recess 14 is more or less deep or wide depending on the dimensions coils to tie.
  • a sector 16 (drawn in dotted lines in FIGS. 4 and 5 in the inactive position) is moved by means of a hydraulic system (not shown) so as to close on each plate 11, on the side of the opening of the recess 14 the circuit of path of the link guide 13. At this time the path of the link guide 13 completely surrounds the wall of the coil.
  • the link guide 13 is defined by a number of links 20 of an open chain which have on one side a toothed rack 21 (see fig. 6 and 7).
  • the links 20 are interconnected by an axis 22 which carries on one side of the link 20 a pulley 23 and on the other side two guide rollers 24 which roll and are guided by guide rails 25, defining the circuit of course.
  • the rollers To stabilize the movement of the link guide along the rails, the rollers have a groove in which is housed the guide rail.
  • the rails 25 are integral with the plate 11, with the exception of the rails mounted on the foldable sector 16.
  • the link guide 13 has a series of pulleys 23 regularly distributed over its length.
  • the link guide 13 must have a length less than that of its travel circuit.
  • the two pinions 26 are spaced apart by a sufficient distance so that at least one of them is in contact with the teeth of the links. This distance is usually slightly less than twice the length of the folding sector 16.
  • the machine according to the invention further comprises means for fixing the link 31 at a point C located along the wall 15 of the coil 1.
  • This point C can be obtained by a clamp 32 holding the end of the link 31 (see fig. 9).
  • the pulley 34 is then made to describe a complete revolution along the oblong circuit of the link guide 13 in the direction of the arrow F (see fig. 4).
  • the link 31, hooked to the pulley 34, is thus pulled around the wall 15 of the reel 1.
  • the pulleys 23, which follow the pulley 34 in its movement guide the link along the route of the guide 13.
  • a screen 33 is placed against the latter to ensure a distance always equal b between the ends C of the link 31 and the wall 15 of the coil 1 (see fig. 9).
  • the link 31 is pressed against this screen 33 so that the end C of the link 31 and the other end D, which is wound around the pulley 34 are superimposed parallel and overlap over a distance L defined by the length of l screen 33.
  • the place of welding is always at distance b from the wall 15 of the coil 1.
  • the welder 35 (see fig. 8) is movable perpendicular to the wall 15 of the coil 1 whatever the diameter thereof.
  • the welder 35 has two clamp arms, one movable, the other fixed, each provided with a link shearing blade. On the ends of the arms are the two welding electrodes 36.
  • the movable arm has a spring system allowing movement of the blade without moving the electrode. This makes it possible to first wedge the ends of the link between the two electrodes, to continue the movement of the arm and to shear the link at point D between the movable blade and the fixed blade.
  • the welding electrodes are then energized and the ends of the link are welded together at two points. Once cut, the link 31 is slightly folded around the pulley 34 and remains attached to it, thanks to folding devices, constituted by an arm activated by a spring and non-return not shown.
  • the hydraulic tensioner located upstream of the pulley 40 is then pressurized and returns the link guide to its starting position.
  • the clamp 32 advances and tightens the end of the folded link around the pulley 34.
  • the screen 33 is mounted on the same assembly which activates and displaces the clamp 32, so that when the screen is then applied under determined pressure against the wall of the coil, the clamp (point C) is always at an equal distance from this wall.
  • rollers instead of integrating the rollers in the chain, it is also conceivable to mount these rollers on the guide rails.
  • link guide instead of driving the link guide by means of a motor and external gears, it is possible, without departing from the scope of the invention, to house an electric motor in one of the links of the articulated structure composing the guide-link.
