Definitions

  • the present invention relates to a machine designed for encircling with one or more bonds certain objects, and relates more particularly, but not exclusively, to a machine of this type, that is capable of binding bundles of metallurgical elongated products such as steel bars for concrete, steel sections, etc. stacked or loose.
  • the object of the present invention is to remedy these various drawbacks by providing a machine of this kind, which meets in a better way than it has been done up to now, the requirements of technique.
  • the invention consists mainly in a machine that includes components which perform the encircling of the object to be bound by the bond by means of a guide that revolves around this object, the rotation of the guide being attained by a crankshaft integral with an arm carrying the aforesaid guide, and being driven by two devices with parallel cranks and pushrods, one of these devices being angularly staggered in relation to the other.
  • the invention also consists in certain other hereinafter mentioned arrangements preferably used together with the aforesaid main arrangement.
  • the invention relates more especially to certain applications and realizations of these arrangements; it relates more particularly, as a new industrial product, to the binding machines ofthe type in question, to the units comprising these machines, together with the elements and suitable tools.
  • F108. 1 and 2 show in a partial side elevation and in plan, respectively, the device for application of the bond in a binding machine according to the invention
  • i lG. 3 shows in elevation a holding gripper for the object to be bound in this machine
  • lFl G. 4 is a view, in partial elevation and cross-section of a mobile gripper of this machine, the said gripper transferring the end of the bond that is used, from a waiting posi tion to the binding position;
  • P16. 5 shows in elevation the device for advancing under tension, the bond used in the machine
  • lFl'GS. ti and 7 show, in elevation, in front and side view respectively, a shearing gripper designed to cut the bond and to hold the cut bond before setting the twist jointing head in motion;
  • F16. H is a view in elevation of the device that twists together the ends ofthe bond laid on by the machine;
  • P10. 9 is a view in elevation of an arrangement of the machine, designed to fold back the ends of the bond that have been twistjointed;
  • F113. 14 is a view in partial cross'section of a detail of the twistjointing device shown in FIG. 8;
  • FIG. 15 shows a diagram of the combination of the various mechanisms which constitute the machine. If it is intended to build a binding machine according to the invention, and, more especially, according to the embodiment as shown and described, together with the realization of its various parts, to which preference should be given, one should proceed as follows or in a similar manner.
  • the binding machine consists of a frame 1 in which the axles of identical cranks 2, 3 and 4, 5 can rotate. On these aides, identical gears 15 and 7 are keyed, and they engage a common gear 8. Gear 8 engages a toothed segment 9 that rotates around axle 10 and is driven by a double-acting jack 1 1 through crank 12. Jack 11 is hinged in 13 round an axle that is fixed in relation to frame 1. By actuating jack 11, one causes the rotation, in one or the other direction, of cranks 2, 3 and 4, 5.
  • cranks 2 and 4 are parallel to one another and are posi tioned on a side of the frame 1; cranks 3 and 5 are parallel to one another and are positioned on the other side of the said frame, but there is a certain angular stagger, of the order of 70, between cranks 2 and 3 this value being not restrictive; the same stagger exists of course between cranks 4 and 5.
  • cranks 2 and 4 on one part, and of 3 and 5, on the other, rotate in bearings supported respectively by push-rods l4 and 15 which move about whilst remaining parallel to the plane of the axis of rotation of the cranks.
  • push-rod 14 extends with a straight part 16 that ends at crosshead 17; beyond the wristpin of crank 5, push-rod 15 carries an extension with a double curvature 18 that ends at crosshead 19.
  • crankshaft can rotate.
  • the axles of crossheads 17 and 19 are respectively in the planes of the axles of wrist-pins of cranks 2, 4 and 3,5.
  • cranks 2, 4, 3 and 5 rotate under the action of jack 11, push-rods 14 and 15 move about, remaining parallel to themselves, and the centers of crossheads 17 and 19 describe equal arcs on circles, the radius of which is equal to the radius of the cranks, the centers of these circles being located at 21.
  • all points ofcrank-shaft 20 rotate also around a center line which is located at 21; it is in particular the case for arm 22 rigidly connected to crankshaft 20, and for pulleys 23, 24, 25 and eccentric pulley 26, which all are carried by this arm 22.
  • the object to be bound consisting in the example by a stack of angle-bars 27, is placed in the proximity of center 21 around which the aforementioned pulleys can rotate.
  • This object 27 is held by an arm 28 operated by a double acting jack 29 swivelling on frame 30 (see FIG. 3).
  • the bond formed by wire 31 unwound from a reel, passes through a stretching device supported by frame 32.
  • This device comprises rollers 33, straightening the wire and restraining its motion, and a winding drum with a mobile arm pulled back by a spring 35 and swivelling about center 36.
  • the swivelling motion of arm 34 is limited by abutments 37 and 38.
  • the end A ofwire 31, held on pulley 25 by eccentric pulley 26, is transferred to B by a mobile gripper 39 supported by frame 40, through two parallel cranks 41, 42. These cranks are driven by a double-acting jack 43 through gears 44 and toothed sector 45. The closing and opening of gripper 39 are driven by double-acting jack 46.
  • a doubleacting jack 47 hinged on frame 48, operates a shearing gripper with an arm 49 hinged in 50 on this frame.
  • the wire of the bond is gripped by jaws 51, and cut by shear 52.
  • These jaws and shear are actuated by jack 47, springs 53 and 54 ensuring respectively the connection of shear 52 which is attached to jack 47 and hinged in 55 on arm 49, with the aforesaid arm 49 and with jaws 51 also hinged in 55.
  • Wire 31 is cut by shear 52, jack 11 returns the mechanism which carries pulleys 25, 26 to its initial position and the cut end of wire 31 return back to A.
  • a double-acting jack 56 hinged on frame 57, thereupon actuates a twisting device carried by a support 58 hinged on frame 57.
  • This device comprises a double-acting jack 59 that causes, through a toothed sector 60 and a gear 61, a twist jointing head 62 to rotate, which grabs the ends of the binding wire, as shown schematically in 62a (FIG. 13).
  • Gripper 39 and jaws 51 are then opened.
  • gear 61 first effects the tightening of gripper 63 in the twist jointing head; to this effect, gear 61 actuates an eccentric 64 which acts on gripper 63; then a pin 65, supported by gear 61, comes into contact with a boss 66 of tubular part 67 of the head; the twist jointing of the ends of the binding wire has thus been performed.
  • gear 61 actuates an eccentric 64 which acts on gripper 63; then a pin 65, supported by gear 61, comes into contact with a boss 66 of tubular part 67 of the head; the twist jointing of the ends of the binding wire has thus been performed.
  • a reverse movement ofjack 59 loosens gripper 63 and releases the twist jointing head 62 which returns to its original position, whereby jack 56 pulls this head back.
  • the twisted bound wires are folded back by a device which comprises a lever 68 hinged in 69 on a frame 70 and actuated by ajack 71 as shown in FIG. 9.
  • the arm 28 which holds the object 27 is opened to allow removing of the bound object, and gripper 39 returns in the open condition, to its starting position A, ready for another binding cycle.
  • the motions of the various jacks can be performed through a programmer; the motion of one jack can also result from a previous operation of anotherjack.
  • a binding machine for encircling with one or more bonds certain objects, particularly bundles of elongated metal products, said machine comprising means for performing said encircling of said object to be bound by said bond, said means comprising a guide adapted to rotate around said object, a
  • a binding machine and a stretching device for said bond, said stretching device having rollers, said device comprising a winding drum having a movable arm and a spring for the return movement of said arm.
  • a binding machine comprising a movable gripper, and two parallel cranks for supporting said gripper, said gripper arranged for holding the end of said bond during binding.
