Definitions
- the present invention relates to an intermediate element for stacking objects such as plates, studs, profiles or the like, usable in particular in the field of sawn timber; the invention also relates to a method of manufacturing spacers of this type and a machine implementing said method.
- stacking slats to separate the wooden cuts, called friezes or edged, in order to prevent the woods from staining or mold when they are stacked in direct contact with each other; similarly, the stacking slats allowing the drying of the woods, which consists, let us remember, of a natural drying of the woods which thus lose their moisture on contact with air, which limits deformations due to climatic constraints as much as possible.
- the slats most commonly used nowadays, are made of white wood, of square or rectangular section, according to very variable dimensions according to their destination; the wooden slats generally have a large contact surface with the woods they support, thus creating stains and mold, not only on the contact areas, but also on all poorly ventilated areas. Furthermore, it is well known that wooden slats have many drawbacks: they deform, absorb moisture, and in addition, they have dimensions specific to each user, which makes them a generally non-reusable product, with a manufacturing cost that is difficult to control for the company that produces its own slats.
- the object of the present invention is to overcome all these drawbacks by proposing an intermediate stacking element which can advantageously replace the stacking slats generally used for drying sawn timber, or even be conveniently used as a support for plates, panels and the like. planks of wood, metal or any other material.
- an intermediate element for stacking objects such as plates, studs, profiles or the like, for example of wood, characterized in that it consists of a strip of a rigid material, such that strip of metal advantageously treated against corrosion, folded in the transverse direction, at regular or irregular intervals, alternately in one direction then in the other, to form a certain number of folds, said strip being intended for vertical use on edge, to provide a stable load distribution system, allowing greater air circulation between the objects thus inserted.
- the folds will be at regular intervals, the thickness and the height of the strip will be determined once and for all, to suit the greatest number, from a strip of split metal, advantageously comprising a solid surface treatment against corrosion.
- the interlayer according to the invention has a longitudinal rigidity and a straightness practically comparable to the wooden slats previously and generally used.
- the ZIG-ZAG shape of the interlayer is particularly advantageous in that the interleaves can be nested one inside the other, making it possible to reinforce the buckling resistance, but reducing also their storage volume, and also making it possible to obtain elements of variable length by juxtaposition of two or more elements of the same type, nested on one or more of their folds.
- the subject of the invention is also a method of manufacturing intermediate elements in accordance with the invention, as well as a machine implementing such a method.
- FIG. 1 is a perspective view of the use of the intermediate stacking element, according to its most general construction
- FIG. 2 represents the same element according to a more elaborate variant with raised edges
- FIG. 3 is an example of a stacking interlayer obtained by juxtaposition of two elements according to the invention fitted onto three of their folds,
- FIG. 4 represents a schematic view of the machine for manufacturing spacers in accordance with the variant shown in FIG. 2 from a reel of slotted metal strip,
- FIG. 5 is a schematic view of the device for reshaping the raised edges, deformed after the stamping of the folds of the interlayer.
- the interlayer stacking element in accordance with FIG. 1 is constituted by a metal strip 1 preferably made of galvanized steel, of thin thickness generally between 5/10 th and 2 mm, drawn from 'A reel of metal strip split along a length that a person skilled in the art will choose to form an element capable of replacing the wooden slats conventionally used for stacking sawn timber for drying.
- the metal strip 1 obviously has a width corresponding to the height of the same wooden slats generally used and which it is claimed to replace, since the intermediate element is intended to work on edge.
- the metal strip 1 is then treated in a general ZIG-ZAG shape by successive folding of said strip 1 alternately in one direction, to the right for example, then in the other to the left, then to the right, then to the left, and so immediately to finally determine the intervals 2 delimited by folds 3 coinciding with the vertices of the ZIG-ZAG.
- the intervals 2 of the strip 1 can be of equal or unequal length, thus determining regular or irregular intervals between the folds 3.
- an intermediate element according to the invention can be arranged on edge and serve as a support for stacks as diverse as plates, studs or profiles of wood or any other material requiring load distribution. It will be understood that such a device is extremely stable insofar as the compression forces are vertical, which results directly from the operation of folding the strip 1 in a direction perpendicular to its longitudinal axis.
- intermediate elements of the same dimension allowing better manufacturing standardization and therefore lower cost and greater ease of storage, while retaining the possibility of producing intermediate supports. of variable length by juxtaposition of standard elements nested two by two by one or more of their folds and counter-folds 3.3 ′ (see FIG. 3 showing a support produced from two elements nested in three folds 3.3 ′) .
- the machine for manufacturing the intermediate elements comprises a supply station 8 for the metal strip 1 slit to the appropriate dimensions; these dimensions will be easily established by those skilled in the art to obtain a given insert.
- the strip 1 is then profiled by the set of rollers 9, 10, 11 and counter-rollers 9 ', 10', 11 'of shape allowing a progressive hardening of the edges 4 or 5 of the strip 1 to bring it to 90 ° relative to the surface of the strip 1; it is well known that such a ribbing operation at the edge of a metal strip is relatively complex insofar as the folding takes place over 1 or 2 mm in height; this is why a progressive profiling has been retained here by the play of a first roller of form 9 carrying out a folding at approximately 30 °, of a second roller of form 10 continuing the folding up to approximately 60 ° followed finally a third roller of form 11 ending the folding at 90 °.
- this profiling operation could undoubtedly be carried out by other means or even by a single passage through a roller of suitable shape.
- the stamping station 12 essentially consists of a set of movable jaws 6 coming to bear transversely on fixed jaws 7 in correspondence; in fact, it is not possible to stamp all the folds of a ZIG-ZAG shape in a single operation; we know, in fact, that such a shape requires significant variations in the length of the strip to be stamped, so that it is only possible to produce the folds 3 one after the other by releasing one end of the strip which can thus retreat by the desired length for each operation; so he was chosen for the machine according to the invention, to install as many movable jaws 6 as plies and counter-pleats 3 desired for the interlayer stacking element.
- a thrust cam 13 moving in the direction of the formation of the folds successively pushes each movable jaw 6 to bring the latter into compression on the - the fixed jaw 7 in correspondence, each time forming a fold and a counter-fold 3; the programmed advancement of the thrust cam 13 is calculated so that the start of stamping of a second ply 3 only occurs when the previous ply is completely produced.
- the free side of the strip 1 engaged in the stamping station 12 making it possible to provide the length necessary for the creation of the ZIG-ZAG.
- a simple jack system 14 keeps the movable jaws 6 in compression on the fixed jaws 7 and this, until the push cam 13 is completely disengaged at the end of the stroke; we then use the rigid assembly formed of fixed jaws 7 and movable 6 in compression as an anvil on which we apply a roller
- finish 15 which comes to reform the raised edges 4 or 5 deformed by the stamping operation. It is obvious that two rollers are provided when the strip 1 has two raised edges, the operation of the second roller 15 'being reversed with respect to the first roller 15 since the direction of folding of the upper edge 4 is reversed with respect to that of the lower edge 5.
- the manufacturing machine according to the invention is, of course , provided with a cutting system 17 at the end, thus allowing continuous operation, a conventional device 18 for ejecting the finished parts will advantageously complete the whole machine.
- the invention is particularly although particularly applicable to the drying of sawn timber.
