Definitions

  • ABSTRACT A machine for automatically and continuously manufacturing reinforcements comprising longitudinal metal members connected by at least one transverse member and comprising a cylindrical bearing mounted on the machine frame and rotatably mounting a drum which carries the transverse member and a wire guide.
  • the drum and wire guide are rotatable about the same axis.
  • the machine also includes devices for drawing the longitudinal members off a store and devices including barrels for moving them parallel to said axis in the direction of the drum.
  • Control means is provided for correlating movement of the longitudinal members with drum rotation to produce a helical binding of the transverse members about the longitudinal members.
  • This invention relates to a machine for automatically and continuously manufacturing reinforcements.
  • Reinforcements in particular for reinforced concrete, are generally constituted by longitudinal parallel members, arranged either in flat sheets, or according to any desired configuration, such as triangular or quadrilateral, which are spaced apart by transverse members, of lesser section than the longitudinal members, to which they are preferably bound or welded. These transverse members, moreover, ensure the resistance of the reinforced concrete to shearing forces.
  • These transverse members are constituted, according to each case, either by rods which are welded to the longitudinal members, or by straps or pins, flat or deformed in two planes forming between them a pre-determinedangle, which are' welded or bound to the longitudinal members, by one or more continuous, appropriately bent, wires, then welded or bound to the longitudinal members.

  • the passage of the abutment 133 to the abutment 134 is effected by means of the jack 135.
  • Symmetric with the control lever 130 of the carriage is a lever 136, connected to a lower frame 137 by a connecting rod 138, and coupled to a bar 139 which is connected to the lever 136 by a connecting rod 140.

  • the control device comprises, in this particular embodiment, a shaft with adjustable cams similar to the control device 25 of the machine of FIG. 1 which ensures synchronism with the rotation of the. ring.
  • This camshaft or control device controls: a four-way valve for controlling the grippers 124; a four-way valve per barrel, the jacks of the catches 128 and 128a being mounted in opposition, the first being necessarily open, when the second is closed and vice versa according to whether the barrel remains stationary or moves forward; a valve for the movable abutment and a valve for the jack 129.
  • the cam shaft is provided with members for the control of associated elements, such as the welding members and cutting tools.
  • the wire guide 11 l pivoted at 112 is additionally able to abut against the longitudinal members, or between the latter, by means of a lever integral with the shaft 112 pivoting the support 105, this lever 150 being coupled to ramps of cams 151 advantageously arranged on the fixed support 127.
  • the wire c arranged in a ring in the drum 15, coiled in the same direction as the wire on the section to be obtained, is drawn from inside the coil, passing through the wire guide 14, and is hooked to one of the bars, for example the bar a.
  • the wire guide 14 and the drum 15 are rotated.
  • the wire hooked to the bar a is stretched between the latter and the wire guide 14.
  • the barrel 18 and the carriage 21 displace in the direction of the drum 15, causing forward movement of the bars a and b.

  • the displacement of the movable assemblies is regulated with a view to obtaining the desired pitch of the winding, by any convenient means, for example by abutments.
  • the reinforcement thus manufactured continues in length and, as it advances step by step, the welding devices 27 and 27a come into action.
  • the wire constituting the transverse members is, initially, specifically wound, in order to be able to be held by the outside of the ring in a cylindrical drum.
  • This arrangement makes it necessary to re-wind the'wire in a can in order to be able to use it, and,-on the other hand, makes it necessary to drive the drum mechanically to avoid the wire winding into a ball.
  • this drum with an inner winding is constituted, in fact, by a specialpart. It may be advantageous to eliminate the aforesaid constraints in the use of the machine-and manufacture of the reinforcements. Thus, it may appear advantageous to do away with the necessity of using a special drum with the aim of reducing cost for the manufacture of the machine. But it may still be moreadvantageous to attempt to do away with having to proceed to a special re-winding of the transverse members onto the drum, an internal re-winding which is-long and troublesome. With this idea in mind, it is also desirable as:a modification to be able to use certain bobbins of standardised dimension.
  • This second machine preferably uses wire bobbin 101 of standardised dimension, wound over a large diameter, or re-wound, if these bobbins do not have a large enough hub, on the drum 102, directly onto the machine.
  • the side 108 with bayonet fastening is removed 'andthe guide 109 is folded back around the axis 110 according to the arrow H.
  • the guide 109 is placed in the axis of the machine and has a transverse dimension less or equal to that of the hub of the bobbins.
  • the reinforcement being manufactured must be cut at C, after positioning of the bobbin, the side 108 being replaced on the drum 102 and the guide 109 being replaced in position for taking the wire above the coil
  • the wire is threaded into the guide 109 as far as the pivoted wire guide 111 according to the axis of the 'return roller 112.
  • the wire having passed .into the rollers of the wire guide at 111 is hooked to the longitudinal member A.
  • the machine then may be 're;started.
  • the ring 104 is then rotated in the direction of the arrow R.
  • the adjustment of the tension of the spiralled wire S coming from the coil 10] is ensured by action on the brake 114.
  • Thefunction of this brake 114 is to neutralise, .at the time of starting, the inertia of the assembly of the drum 102 relative to the wire guide assembly, in particular'the ring 104.
  • the longitudinal members A and B are taken up in coils on the drums, or in straight bars, and pass into alignment devices with rollers 120, which, in addition to displacing them,.rectify them and immobilise them.
  • the assembly advances by the movement of the carriage, the members A and B being effectively gripped by the grippers 124.
  • either the barrell'26 of the member A, or the barrel 126 of the memberB pushes the wire S.
  • the guide relative to the member A has its catch 128 open, and the barrel is closedby the catch 1280 in the guidel 25a.
  • the catch 1280 of the guide 125 relative to the member B is engaged in the groove of the corresponding barrel I26 and this barrel is pushed through-the guide 125a relative tothe said member B, the corresponding catch 128a'being open.
  • the above described reinforcement arrangements with two longitudinal members are valid for any other arrangement with three or four longitudinal members or even more, such as those shown with regard to FIGS. 6and 7; a reinforcement with three members is'shown in FIG. 6 while a reinforcement with four members arranged in a trapezium is shown in FIG. 7.
  • the winding pitch of the transverse membersaround the longitudinal members may be any desired value and is regulated by acting on the forward-movement of the said transverse members during the bending operations.
  • the reinforcement shown in FIGS. 4 and 5 may be obtained.
  • the longitudinal members do not rotate about the axis of the reinforcement, which makes it possible to. manufacture the reinforcement continuously and in very great lengths.
  • the machine may in addition be provided with any associated device, such as a special de-carbonising device, an automatic shearing machine, a device for receiving, curving or winding, or any means for forming the reinforcements.
  • the machine may also be used to manufacture loose members, without welded bars, constituted by a wire coiled according to a chosen section and pitch, this replacing the longitudinal members by smooth pins locked in the barrels.
