Definitions

  • the present invention relates to a portable device or clamp for ligating bars, rods or the like by means of a flexible metallic wire.
  • Pliers are also known which include a rotating halyard on a pull handle by hand, the end of which engages in the two closed loops of a piece of metal wire, mechanically shaped beforehand, and which are placed in semicircle around the bars to bind.
  • the traction carried out on the handle causes the rotation of the driller and the formation of the twist of metal wire which binds the bars. This method is also very slow and tiring.
  • Patent FR-A-2401742 describes a tool for placing a ligature in the form of a flexible strip on bundles of wire which includes jaws, one of which is articulated, inside which the wires to be tied are placed.
  • a manual operation in translation of a rod secured to a carriage successively causes the advancement of the band, the closing of the upper jaw, the conformation of the band in a loop in contact with the jaws, then the introduction of the end of the strip in a mount and shear of the strip.
  • Such a tool has the drawback already mentioned of limiting its application to bundles of wires whose section does not exceed the volume limited by the jaws and, consequently, the section of the preformed loop.
  • the object of the present invention is to overcome such drawbacks by eliminating the need for prior shaping of the wire on a template. It relates more particularly to a device for ligating bars, rods or the like by means of a flexible metallic wire, comprising means for advancing and guiding the wire, jaws composed of a fixed lower beak and a beak upper pivoting about an articulation axis, as well as shearing means and which is characterized in that it also comprises a torsion head provided with means for retaining the wire serving for tying and means for driving it in rotation and a groove for the setting of the tying bars formed by the fixed lower beak and a guide of the upper beak, the upper beak, guided laterally by means of said guide, is movable in translation in direction parallel to the axis of rotation of said torsion head and biased by means of a spring towards the lower spout, its end being constituted by a gripping hook so that the free end of the ligature wire passing through the means for retaining the torsion
  • the ligature head having no guide or template to conform the looped wire, it can be flat, thus making it possible to perform ligatures in places that are not easily accessible, such as the angles, and in all positions, in a cross or in parallel.
  • the strapping of the ligature is made according to the invention by bypassing the bars to be tied and not by preforming a loop in a template head of fixed dimensions.
  • the movable upper spout consists of two sheet metal plates, parallel, spaced apart by an interval greater than the diameter of the wire used for binding, a roller connecting towards the 'front end of the spout the two plates and serving as a gripping hook and tie wire.
  • This roller maintains the tension of the wire around the bundle to be tied by sliding wedging, when the spout describes a trajectory bypassing said bundle.
  • the torsion head can have an internal bore to receive the lower strand of the wire, parallel to the longitudinal axis of the torsion head and a slot along the generatrix situated in the diametrical plane of the bore to receive the upper side of the wire, with locking pawl preventing the exit of the side during rotation.
  • the guide of the wire towards the hook of the movable spout can be ensured by a central groove made in the fixed lower spout.
  • the clamp comprises two jacks.
  • the first serves to ensure the back and forth translation movement of the movable spout and the end of its rod is articulated on the rear end of the movable upper spout.
  • the second cylinder drives the torsion head in rotation, the cylinder rod pushing on a slider mounted on a spiral screw with several turns secured to the torsion head.
  • the cylinders preferably pneumatic, can be controlled by a sequential control unit.
  • the housing 1 of the clamp may be made of injected plastic material houses the various mechanical parts which will be discussed then far, then forms at the front, on the one hand the fixed lower spout 2 and, on the other hand, the guide of the upper fork-shaped spout 4.
  • the spout 2 and the guide 4 form a groove, at the bottom of which the bars or rods to be tied 12 are placed by wedging them.
  • the upper spout movable in translation 3, guided in the fork of the spout 2, consists of two cut sheet metal plates, parallel and spaced apart by a space greater than the diameter of the ligature wire.
  • the end of the spout has an axis 16 connecting the two plates and carrying a rotary roller.
  • the spout 3 is articulated at 5 at the end of the rod 6 of a jack 9 and a spring 29 biases the spout 3 in the direction of the lower spout 2 and its pressure tends to forcefully apply the spout 3 to the bars to be tied .
  • the lower spout 2 is made up of three sheet metal plates placed side by side, the recessed central plate of which creates a groove 25 for the passage of the tying wire.
  • the jack 7 ensures by means of its rod 6 the comings and goings of the movable spout 3 articulated at 5 to this rod, the axis of the articulation 5 being guided horizontally by a rail integral with the casing 1.
  • the jack 9 ensures both the supply of the device with a ligature wire and the rotation drive of the torsion head 17.
  • the system for supplying the ligature wire comprises a train of three notched rollers 14 driven by gears pushed by a rack (not shown) actuated by the jack 9 and a guide tube 15.
  • rollers exert pressure on the wire which slides on a self-lubricating plastic pad.
  • the rollers are disengaged by means of a ratchet on the gears to prevent the return of the wire back.
  • a torsion head 17 secured to a spiral screw 21 with several turns.
  • a slider 20 fixed on the end of the rod 8 of the jack 9.
  • the torsion head 17 consists of a cylinder comprising a longitudinal bore 27 parallel to the axis intended to pass the lower strand of the ligature wire.
  • a slot 28 On the top of the cylinder, along the generator diametrically opposite to the bore 27, is a slot 28 provided with a locking pawl 30 and intended to receive the upper strand of the ligature wire.
  • a wire cutter 19 is arranged flush with the inside face of the torsion head 17 to cut the two strands of wire. It consists of two jaws 26 working in opposition and leaving between them a recess for the passage of the spiral screw 21 causing the torsion head 17 to rotate.
  • the end of the rod of the jack 9 comprises a cam which separates the two arms of the shears 19 by sliding between the two bosses located inside the arms. This spacing cuts the two strands of wire.
  • the two cylinders are preferably actuated by a bottle of compressed air at approximately 2 bars and their action is coordinated by a sequential time delay unit 10 ensuring the control of alternating and consecutive movements.
  • the upper spout 3 In the initial position when the work cycle stops, the upper spout 3 is in the position shown in Figure 1, the bars 12 are placed at the bottom of the groove formed by 2 and 4, the clamp is supplied with ligature wire in reel 13 and the wire is engaged in the wire push rollers 14 and in the wire guide tube 15 as far as the shears 19.
  • the actuator 9 is actuated forwards, which causes the thrust of the wire which leaves the tube 15 as a result of the action of the notched rollers 14, penetrates into the bore 27 of the torsion head 17 and follows the groove 25 to the end of the spout 2.
  • the action of the jack 9 temporarily stops there. Actuate the cylinder 7 towards the rear of the clamp which pulls the upper spout 3 towards the rear.
  • the end of the wire is snapped up by the upper spout 3 passing over the roller 16, the wire slides between the spaced plates of the spout and, the spout being forcefully applied downwards by the spring 5, it applies the tying around tie bars, forming the hoop exactly matching the perimeter of the bundle of tie bars.
  • the jack pulls back the closing cam of the shears 19 and the two strands of the loop are cut. Then, this cam drives the cursor 20 to the end of the stroke, which ensures the rotation of the screw 21.
  • the spiral screw turning, the rotation head 17 performs several turns which form the twist of the ligature 18, the two strands being held back. The ends of the two strands slide out of the head 17 and the ligature is finished, the linked bars are released.
  • the actuator 7 is actuated in the opposite direction, for example by means of a return spring, the rotation in the opposite direction of the head 17 is not a problem, since the strands are no longer retained by it.
  • the upper spout 3 is thus brought back to its initial position, which makes it possible to place in the groove of the fixed spout 2 bars to be tied, for the following ligature.
  • the device according to the invention is light and therefore portable. It allows you to tie wherever you want, only the size of the pliers' nose limits its use. It also allows fixed-station work.
  • the materials used to manufacture the clamp are sheet metal elements and tubes, bent or welded together.
  • the wear elements can be made of treated steel.
  • the pneumatic components of the motor control are those available on the market, such as the double-acting cylinder and the timing unit.
