  • spacer structures are used in the construction of prefabricated elements or floors, to space apart different reticular reinforcing layers, before casting the concrete.
  • These structures are shaped as a ladder or trellis, being constituted by at least one pair of, more commonly, three or four, parallel longitudinal elements suitably spaced, joined, preferably by electro-welding, to a plurality of transversal elements, generally of reduced length compared to the longitudinal elements, arranged parallel and suitably spaced.
  • Patent application EP 0715923 illustrates a welding apparatus for making metal meshes, comprising elements for supplying longitudinal metal wires and an element for supplying transversal metal wires, as well as cutting means for separating the meshes made.
  • the object of the present invention is to solve said drawbacks by devising a method and an apparatus to make spacer structures, which allows to realize such structures in an effective, versatile manner.
  • the method for making spacer structures provides for arranging at least one first supply assembly for the longitudinal elements along a longitudinal direction and a second supply assembly for the same longitudinal elements, an insertion assembly configured to insert at least one transversal element at a time along a transversal direction in an insertion channel, a cutting assembly associated with the aforesaid insertion assembly, acting in correspondence with a cutting plane transversal to the aforesaid transversal insertion direction, a joining assembly for joining, preferably by electro-welding, the longitudinal elements supplied to the transversal elements.

  • the method provides moving at least one of the first supply assembly and the second supply assembly along the aforementioned transversal direction between an operating area, within which the joining of the longitudinal elements can take place with the transversal elements fed from time to time, by means of the joining assembly, and at least one drop-off area, arranged externally to the aforesaid operating area, laterally thereof, in which it is possible to carry out further operations simultaneously, for example for setting the present supply devices, in particular changing the supplied longitudinal element, replacing the welding electrodes, maintenance.
  • first supply assembly and/or the second supply assembly are associated with moving means to be movable along the aforesaid transversal direction, for example actuating means of a known type.
  • the aforesaid drop-off area is substantially delimited by the aforementioned cutting plane and opposed to the aforesaid channel for the insertion of the transversal elements disposed in the aforementioned operating area.
  • the drop-off area serves to house at least one feeding unit for the longitudinal elements, in order to be able to perform several operations simultaneously during the same production cycle: for example, the replacement of the longitudinal elements in a supply assembly that is stationary in the drop-off area, and the execution of a spacer structure in the operating area by the remaining supply assembly of the longitudinal elements. All the operations described can take place in complete safety in the aforementioned drop-off area while the other supply assembly is engaged in normal production in the operating area.
  • the at least one drop-off area is arranged, preferably, outside the area in which the positioning of the transversal elements can occur, so as not to obstruct the operating area in any way.
  • the aforementioned drop-off area represents an area in which at least one supply assembly can operate an extra-stroke in the aforesaid transversal direction and remain stationary, to be arranged, meanwhile, for a subsequent work cycle.

  • each supply device of the first supply assembly or, respectively, of the second supply assembly of the longitudinal elements is associated with a joining unit of the joining assembly.
  • each joining unit is preferably integrally associated with the respective supply device of the longitudinal elements, so as to follow the movements of the latter when it is necessary to change the format of the spacer structure to be made and therefore reduce the number of adjustments to be made.

  • the positioning of at least one cutting assembly provided and therefore of the corresponding cutting plane can be advantageously adjustable in the transversal direction between a position approached to the insertion channel, and therefore to the operating area, and a position apart from the same insertion channel, therefore from the same operating area.
  • the possibility of adjusting the transversal positioning of the cutting assembly allows, in particular, to provide spacer structures without protrusion of the transversal elements with respect to the longitudinal element to which they are joined, or with a protrusion of controlled extension.
  • the control of the extension of this protrusion is important since it determines, locally, the amount of the cover therefore the protection of the reinforcement against external corrosion agents and also the acoustic transmission of the final product.
  • the apparatus according to the invention is indicated with 1, for making spacer structures 2, by joining at least one pair of longitudinal elements 3, arranged parallel and suitably spaced, to at least one transversal element 4.
  • longitudinal element 3 and transversal element 4 are preferably meant metal wires, intended to be arranged longitudinally or transversely in a spacer structure 2.

  • the apparatus 1 comprises at least a first supply assembly 10 of the longitudinal elements 3, along a longitudinal direction A, at least a second supply assembly 100 of the longitudinal elements 3, an insertion assembly 20 of the transversal elements 4, along a transversal direction B, a cutting assembly 30 of the transversal elements 4 inserted, associated with the insertion assembly 20, and a joining assembly 40 of the longitudinal elements 3 to the transversal elements 4 (see in particular Figure 1 and Figure 9 ).
  • the joining assembly 40 is operative inside an operating area 50, for joining the longitudinal elements 3 supplied to the transversal elements 4 inserted and cut, as better described below.

  • each supply device 5, 6 can comprise a pulling unit 7, for example realized by means of pairs of opposite wheels with respect to the aforementioned longitudinal direction A, and a winding gear member 8 (see Figures 4 and 5 ), preferably mounted on a tiltable frame according to the aforementioned longitudinal direction A, to reduce the stresses to which each guided longitudinal element 3 is subjected, during the joining step.
  • the insertion assembly 20 of the transversal elements 4 is configured to guide and insert each transversal element 4 inside an insertion channel 9, along the aforesaid transversal direction B.
  • the insertion channel 9 is defined inside an operating area 50 of the apparatus, described in detail below, inside which each spacer structure 2 is intended to be made.
  • the insertion assembly 20 cooperates with a positioning device 21, for example of the gripping type, movable between a rearward configuration 21a and an advanced configuration 21b, with respect to a supplying direction of the longitudinal elements 3 in the longitudinal direction A, to take each transversal element 4 from the insertion channel 9 defined at the aforementioned rearward configuration 21a and bring it to a joining station in which the joining assembly 40 operates (see Figures 3 and 4 ).
  • a positioning device 21 for example of the gripping type, movable between a rearward configuration 21a and an advanced configuration 21b, with respect to a supplying direction of the longitudinal elements 3 in the longitudinal direction A, to take each transversal element 4 from the insertion channel 9 defined at the aforementioned rearward configuration 21a and bring it to a joining station in which the joining assembly 40 operates (see Figures 3 and 4 ).
  • the insertion assembly 20 also cooperates with the cutting assembly 30, preferably of the shear type, for supplying each transversal element 4 and cutting it to size at the aforementioned insertion channel 9.
  • the cutting assembly 30 can preferably be transversely movable, with an adjustment motion in the transversal direction B.
  • This adjustment motion has, in particular, the function of adjusting the extension of the possible protrusion of each transversal element 4, with respect to the longitudinal elements 3 supplied, in the structure 2, once it is joined by the joining assembly 40.
  • the cutting assembly 30 is movable along the transversal direction B of an adjustment stroke, between an approached position 30a, with respect to the insertion channel 9, and a position 30b apart, with respect to the same insertion channel 9 ( Figure 6 ).
  • the insertion assembly 20, the respective positioning device 21, if provided, and the cutting assembly 30 are preferably arranged below the supplying plane of the longitudinal elements 3. This arrangement is advantageous in that it allows the tangency plane to remain unaltered between longitudinal elements 3 fed and the transversal elements 4 inserted, whatever the size of the cross-section of the longitudinal elements 3, which in some cases may also be different in the same structure 2.
  • the joining assembly 40 is preferably of the type configured to carry out the joining by electro-welding of the longitudinal elements 3 with the transversal elements 4.
  • the joining assembly 40 preferably comprises a pair of electrodes 41, 42, respectively upper and lower, associated with each supply device 5, 6, for each supply assembly 10, 100.

  • first supply assembly 10 and the second supply assembly 100 are configured to be operated in motion along the transversal direction B, for example by actuation means of the known type.
  • the apparatus 1 is configured to define the aforementioned operating area 50 inside which the transversal elements 4 are supplied into the insertion channel 9 and cut, to be joined to the longitudinal elements 3 and, outside it, at least a drop-off area 60, inside which at least one supply device 5, 6 of a respective supply assembly 10, 100 can remain stationary to carry out preliminary operations to the subsequent operating cycle, for example the replacement of the longitudinal element 3 supplied with another of a different type.
  • the aforesaid operating area 50 is bounded transversely by the cutting plane, fixed or movable inside the aforementioned adjustment stroke of the cutting assembly 30.
  • the aforementioned apart position 30b of the cutting plane determines the maximum extension of a transversal element 4 inserted in the insertion channel 9 which can be cut, positioned in correspondence with the joining assembly 40 and subsequently joined, by means of the apparatus 1, to a longitudinal element 3 which is supplied by a supply assembly 10 or 100 (see in particular Figures 6 and 7 ).
  • the drop-off area 60 is essentially an extra-stroke zone of the supply devices 5, 6, arranged laterally to the cutting assembly 30 and/or, more precisely, beyond the respective fixed or movable cutting plane of the cutting assembly 30.
  • the supply devices 5, 6 can therefore be preferably arranged as stationary in the aforementioned drop-off area 60, to perform, for example, operations of replacing the longitudinal elements 3, while the other supply assembly 100 and the respective associated joining assemblies 40 can carry out the joining operations necessary for the realization of a spacer structure 2.
  • the supply devices 5, 6 can simply remain stationary in the aforementioned drop-off area 60, simply carrying longitudinal elements 3 for the subsequent production cycle.
  • the first supply assembly 10 is operative: for example, the first supply device 5 and the second supply device 6 supply respective longitudinal elements 3 along the feeding direction A in correspondence of the operating area 50.
  • the insertion assembly 20 inserts a transversal element 4 in the mentioned insertion channel 9.
  • the joining assembly 40 thus operates the joining of each longitudinal element 3 supplied with the transferred transversal element 4.
  • the joining assembly 40 releases the joined portions of the longitudinal elements 3 and of the transversal element 4, respectively.
  • the supply devices 5, 6 then advance the same longitudinal elements 3 of the predetermined pitch, depending on the structure 2 to be made.
  • the second supply assembly 100 can wait idle inside the same operating area 50, having preferably already inserted and ready for the subsequent feeding, longitudinal elements 3 suitable for the subsequent production cycle.
  • the first supply assembly 10 can unload the just completed structure 2, preferably, by moving along the longitudinal direction A (see Figure 8 ).
  • the second supply assembly 100 is moved along the transversal direction B, for example in a direction opposite to the direction of insertion by the insertion assembly 20 (see Figure 9 ), inside the operating area 50, to be approached to the insertion assembly 20 and to the cutting assembly 30 associated therewith, arranged in a position suitable for the new structure 2 to be made, intermediate or extreme between the approached position 30a and the apart position 30b.
  • the first supply assembly 10 can be usefully kept stationary in the drop-off area 60, by moving in the same transversal direction B, always in the opposite direction with respect to the direction of insertion of the transversal elements 4.
  • the first supply assembly 10 or at least one respective supply device 5, 6 of the same first assembly 10 is positioned beyond the aforementioned cutting plane defined by the cutting assembly 30.
  • a new production cycle of the subsequent spacer structure 2 can thus be initiated by the second supply assembly 100 (see Figure 10 ).
  • the first supply assembly 10, or at least one of the supply devices 5, 6 composing the same can remain idle in the respective drop-off area 60.
  • the aforesaid adjustment of the protruding portion 4a can take place due to the adjustment of the relative distance between the longitudinal element 3 intended to be external to the spacer structure 2 to be made and the plane in which the transversal element 4 is cut by means of the cutting assembly 30.
  • This distance is preferably regulated through the positioning of the cutting assembly 30, which is preferably adjustable continuously between the approached position 30a and the apart position 30b.
  • the possibility of moving the cutting assembly 30 inside the aforementioned adjustment stroke makes it possible to avoid the use of means for moving each transversal element 4 along its longitudinal axis, which would require the presence of further members.
  • the apparatus 1 can comprise a further insertion assembly 20 and a further cutting assembly 30 associated therewith, very similar to those previously described and opposite to them along the transversal direction B, with respect to the insertion channel 9 arranged in the operating area 50. In this way it is possible to insert and cut to size transversal elements 4 from both sides of the insertion channel 9.
  • the same operating area 50 is delimited, on one side, by the cutting plane, fixed or movable of the cutting assembly 30, and, on the other side, by the corresponding further cutting plane, fixed or mobile, of the further cutting assembly 30.
  • first supply assembly 10 and the second supply assembly 100 are preferably both transversely movable, along the transversal direction B, both inside the operating area 50 and in the drop-off areas 60 on each side of the insertion channel 9 and, therefore, of the operating area 50, so as to considerably increase the flexibility of the apparatus 1.
  • the method and the apparatus according to the invention therefore make it possible to produce spacer structures in a very flexible manner, responding promptly to specific production requirements.
  • the materials used, as well as shape and dimensions, may be any according to requirements.
