Definitions

  • the present invention relates to a method and an apparatus for forming packs of stirrups and to the pack of stirrups thus formed.
  • the reinforcement frame of reinforced concrete pillars and beams is commonly formed by using metal frames constituted by longitudinal iron rods connected by suitably spaced transverse stirrups.
  • the stirrups usually form a closed path, for example a quadrilateral one, with overlapping ends.
  • the longitudinal rods are inserted in the profile formed by the stirrups and are fixed, for example at the corners of said profile.
  • stirrups are formed by appropriately provided stirrup bending machines according to the required profile. If the stirrups are not meant for immediate use at the production site, they must be grouped in order to be able to store them tidily. This operation is currently performed manually by assigned operators, with obvious discomfort and fatigue.
  • one common operating method entails allowing the stirrups that exit from the stirrup bending machine to drop to the ground, where they gradually accumulate. The operator then picks up the stirrups and places them in a tidy pack to be bound by way of suitable bindings or the like.
  • the stirrups that pile up on the ground can easily become entangled, so the operator also has to pick them up from the ground and disengage them from each other before tidying them up, which leads to an increase of the work required.
  • the stirrup bending machine must be stopped, for obvious reasons, and therefore its productivity is penalized by this operation.
  • the aim of the present invention is to solve the cited problem, by providing a method that allows to produce automatically packs of stirrups for reinforced concrete.
  • an object of the present invention is to provide an apparatus that allows to perform said method for forming packs of stirrups by way of a structure that is simple in concept, safely reliable in operation, and versatile in use.
  • Another object of the present invention is to provide a pack of stirrups that has innovative characteristics as regards ease and versatility of use and formation.
  • the present method for forming packs of stirrups characterized in that it comprises the steps of:
  • the reference numeral 1 generally designates a working head of the apparatus for forming packs 10 of stirrups 12 for reinforced concrete according to the present invention.
  • the apparatus according to the invention duplicates, in its general features, the structure disclosed in co-pending Italian patent application BO2002A000438, by the same Applicant, to which reference is made for a more complete general description.
  • Patent application no. BO2002A000438 relates to an apparatus for forming metal cages for reinforced concrete, and therefore the present invention relates to a different application of said structure.
  • the apparatus is adapted to be associated with a conventional stirrup bending machine 2; it should be noted that the stirrup bending machine 2 has a working surface that is arranged vertically for the sake of convenience.
  • the apparatus has a chassis, not shown, which is provided with the working elements and is arranged in front of the stirrup bending machine 2.
  • a longitudinally elongated platform 3 protrudes from the chassis and forms a horizontal working surface.
  • the packs 10 of stirrups are meant to form on the working surface of the platform 3 and are obtained, as specified hereinafter, by joining one or more longitudinal auxiliary rods 11 externally to a tidy series of said stirrups 12.
  • the auxiliary rods 11 unwind from corresponding spools, not shown, which are arranged preferably with a vertical axis at the sides of the platform 3.
  • the chassis of the apparatus supports, in a suitably adjustable position, at least one working head 1, which is adapted to pick up the stirrups 12, form the pack 10 and weld a respective auxiliary rod 11 to the stirrups 12.
  • the stirrups 12 form a substantially rectangular profile and are mutually connected by way of three auxiliary rods 11, which are arranged respectively on the lateral portions and on the lower portion of the stirrups 12, and therefore three working heads are required.
  • Each working head 1 is provided with means 5 for gripping and welding the auxiliary rod 11 and the stirrups 12 which form the pack 10 of stirrups.
  • said gripping and welding means 5 provide a grip element 51, which is constituted by a beak 52 that is directed toward the stirrup bending machine 2 and is rigidly coupled to the stem 53 of a linear actuator 54.
  • the actuator 54 is fixed to a bracket 55, which is rigidly coupled to a stem 56 that is guided so that it can slide, in contrast with elastic means 57, through a sliding block 58, which in turn is rigidly coupled to the stem 60 of a second linear actuator 61, along an axis that is parallel to the axis of the first actuator 54.
  • the second actuator 61 is supported by a brace 63, which is provided with a pair of stems 64 for guiding the sliding block 58.
  • the bracket 55 is provided with a housing 65 for protecting the beak 52.
  • the bracket 55 is further provided with a protruding roller 59, adapted to act as an abutment on the front surface of the stirrup bending machine 2.
  • the brace 63 is fixed to the end of a pair of horizontal guiding shafts 66, which pass slidingly through a body 67. At the opposite end, the shafts 66 are fixed, by means of a plate 68, to the stem 69 of a double-stroke grip actuator 70.
  • the body 67 is fixed to a box-like enclosure 74, which acts as a support for a transformer element 75.
  • a rack 76 is rigidly coupled to the enclosure 74 in a downward region and is adapted to couple to a corresponding gear 73, which is turned by suitable motor elements.
  • the welding means 8 are supported in a cantilevered fashion in front of the enclosure 74 and are constituted by movable welding units 81, which cooperate with fixed welding units 82, for example of the resistance welding type, which are open in a forward direction.
  • the movable welding units 81 are supported by an arm 83, which is suitable to be actuated by a linear actuator 84.
  • the fixed welding units 82 are mounted on a body 85, which is supported elastically on stems 86 in contrast with elastic means 87.
  • the method for producing packs of stirrups for reinforced concrete by way of the described apparatus mainly entails picking up automatically or manually the stirrups 12 on the stirrup bending machine 2, which for this purpose is arranged, so that its working surface is preferably vertical, in front of the apparatus according to the invention, at an input region E thereof.
  • the apparatus grips the stirrups 12 to be picked up by means of the grip elements 51 of the working heads 1 before the step for cutting the stirrups 12 from the material in bar or coil form from which they are obtained by bending.
  • the grip elements 51 are moved by the double-stroke grip actuator 70 into a grip position formed by the abutment of the roller 59 on the stirrup bending machine 2, with the beak 52 open onto a corresponding portion of the stirrup 12 ( Figure 2).
  • the grip elements 51 grip two stirrups 12, which are provided simultaneously by the stirrup bending machine 2, which is of the so-called twin-rod type.
  • the apparatus can operate likewise with a single stirrup 12 or with multiple stirrups 12, depending on the characteristics of the stirrup bending machine 2.
  • the beak 52 is then closed by way of the actuator 54 in order to clamp said portion of the stirrups 12 ( Figure 3).
  • the elastic support of the actuator 54 by means of the stem 56, which can slide in contrast with the elastic means 57, causes by reaction the movement of the bracket 55 and accordingly causes the automatic centering of the stirrups 12 on the grip elements 51.
  • stirrup closure sequence has therefore been devised which offers the best results and allows to prevent said stirrups from being gripped and then locked in a position that is deformed due to the elasticity of the material, which undergoes deformation due to its own weight.
  • stirrups 12 After the stirrups 12 have been gripped by the grip elements 51, said stirrups 12 are cut by the conventional cutting elements of the stirrup bending machine 2. The stirrups 12 gripped by the grip elements 51 are then moved in a longitudinal direction by the actuation of the corresponding double-stroke actuators 70 or the like, until a preset working position ( Figure 4) is reached.
  • the actuation of the welding means 80 is activated.
  • the lifting of the movable welding units 81 on the part of the actuator 84 is activated ( Figure 5), followed by a suitable retraction stroke of the grip elements 51 actuated by the actuator 70, in order to place the stirrups 12 at said movable welding units 81 ( Figure 6).
  • stirrups 12 are then gripped between the welding units 81 and 82 and released by the grip elements 51, which advance again, by a limited extent, in order to disengage from said stirrups 12 ( Figure 7). It should be noted that in this step the welding units 81 and 82 do not clamp the stirrups 12 fully, but close only to the extent sufficient to prevent only the fall of the stirrups 12, or as an alternative it is possible to provide additional stirrup retention elements, for example of the mechanical or magnetic type or the like.
  • the grip elements 51 are then moved into a lowered position by means of the actuation of the second actuator 61, in order to allow the return stroke of said grip elements 51 without interfering with the subsequent working steps of the welding means 80 ( Figure 8).
  • the return stroke of the grip elements 51 is also performed through the actuation of the double-stroke actuator 70.
  • the welding means 80 initially place the first pair of stirrups 12 at a preset position, starting from which the pack 10 is formed.
  • said stirrups 12 are clamped by the welding units 81 and 82 and are welded to the auxiliary rods 11, which are simultaneously fed in a longitudinal direction outside said stirrups 12.
  • the welding means 80 then perform a return stroke to the preceding active position in order to pick up a subsequent pair of stirrups 12 from the picking elements 51, which in the meantime have in turn picked up said pair of stirrups 12 from the input region E of the stirrup bending machine 2, in the manner described earlier.
  • Said subsequent pair of stirrups 12 picked up by the welding means 80 is transferred into a forward position adjacent to the first pair of stirrups 12, which is moved to said preset position and there welded likewise to the auxiliary rods 11.
  • stirrups 12 are welded to the auxiliary rods 11, so as to form the pack 10.
  • the mutual distance between the stirrups 12 is generally limited and is preferably such as to arrange said stirrups tidily and equidistantly in contact with each other.
  • the stirrups 12 have a closed profile with overlapping ends, as shown in Figure 1, said distance is substantially equal to the diameter of the rod.
  • the auxiliary rods 11 are constituted by rods that have any cross-section and are preferably narrower than the stirrups 12. Of course, in addition to having a circular cross-section, the auxiliary rods 11 can have a flattened shape or other similar shapes. It is further possible to provide on the auxiliary rods 11 suitable shaped portions or distinctive elements of any kind, for example a series of suitably spaced recesses.
  • auxiliary rods 11 are preferably narrow with respect to the stirrups 12, said stirrups are not affected by the welding step, which instead causes the local melting of the auxiliary rods 11 alone.
  • the auxiliary rods 11 are welded to the stirrups 12 so as to allow their easy separation subsequently, when the stirrups 12 are used.
  • the welding can affect only some of the stirrups 12 that are arranged mutually adjacent so as to form the pack 10 or can be very limited. It is obvious, however, that at least the first and last stirrups 12 of the pack 10 are necessarily welded to the auxiliary rods 11.
  • the pack 10 thus formed is moved away from the platform 3 after cutting the auxiliary rods 11.
  • provisions can be made to provide a weakening of the auxiliary rods 11 at the last stirrup 12 of the pack 10, so as to produce the cutting of said rods 11 through a suitable traction applied to the pack 10, without having to resort to cutting elements.
  • the welding means 80 are moved into a fixed forward position, in which the stirrups 12 are clamped by the welding units 81 and 82 and welded to the auxiliary rods 11. Then a further limited advancement stroke of the welding means 80 is actuated, so as to clear said fixed position in order to allow the subsequent work cycle.
  • the welding means 80 first move the pair of picked-up stirrups 12 closer to the already-formed pack, and then weld said stirrups 12 to the auxiliary rods 11 and produce the advancement of the entire pack 10 by one step, in order to clear said fixed position, which in the examples cited above is substantially equal in extent to the diameter in the case of open stirrups and substantially equal to twice the diameter for closed stirrups in which there is an overlap.
  • the stepwise advancement of the pack 10 being formed of course causes the corresponding traction of the auxiliary rods 11 welded to the stirrups 12.
  • the auxiliary rods 11 can be retained by suitable locking means. Furthermore, welding can be performed during motion or in stationary conditions.
  • the method and the apparatus according to the invention allow to form automatically packs of stirrups for reinforced concrete, eliminating the need for the operator to pick up the stirrups that exit from the stirrup forming machine, tidy them up and bind them in a pack. This clearly allows to optimize the productivity of the machines in addition to freeing the operator from an awkward and potentially dangerous task.
  • auxiliary rods 11 can be joined to the stirrups 12 by way of any type of coupling, particularly by means of any welding method.
  • the rods 11 can be on any side of the stirrups 12, and there may be even more than one rod per side, according to the requirements.
  • the method for moving the frame being formed may also be any, by traction or pushing, for example by using traction wheels integrated in the straightening unit.
  • the shape of the stirrups 12 can in fact be of any kind, even a very complex one.
  • Figure 10 illustrates a pack that is formed with stirrups that have an open configuration. In this case, since the stirrups do not have overlapping portions, it is possible to arrange the stirrups in close contact with each other.
  • Figure 11 instead shows a pack that is formed with closed stirrups that have a more complex geometry.
  • the materials used may be any according to requirements.
