Definitions

  • the present invention relates to a method of manufacture of plates based on hydraulic binder such than plaster, these plates having thinned edges.
  • the invention also relates to a line of production of such plates and a device can be used to make these plates.
  • the assembly thus produced of several plates constitutes a continuous surface with good flatness.
  • the solution offered by the first of these patents consists of making a transverse groove in the sheet of lower paper by folding the latter before the pouring of the plaster composition and arrival on the conveyor belt.
  • the transverse groove making protruding from the bottom sheet of paper creates, once the sheet of paper on the carpet carrier, a hollow whose walls are at an angle. In then cutting the plate at the end of each part at an angle, we obtain two plates with transverse edges thinned.
  • the object of the invention is therefore to propose a method allowing the manufacture of plasterboard having thinned transverse edges. This process achieves remedy the drawbacks of the techniques proposed in prior art.
  • the invention also relates to a line of production of hydraulic binder plates having edges thinned from a preform comprising at least minus one facing material covered with a composition of hydraulic binder, this production line comprising a sector, as well as, upstream of this means, for introducing, under the material of facing, a slat whose length is approximately at least equal to the width of the facing material.
  • transverse edges is meant in the present exposed edges perpendicular to the direction of travel conveyor belt in a production line of hydraulic binder plates.
  • the hydraulic binder composition includes preferably plaster.
  • the facing materials 1 and 3 can be made sheets of paper or cardboard, glass mats or any material known to those skilled in the art as being capable of serve as facing material.
  • a slat 6 is inserted between the facing material 1 and plate 403.
  • This plate 403 may have been obtained by cutting a piece of a plate 404 so as to create plate 403 and between this last and the rest of plate 404 a space for the introduction of the slat 6.
  • the introduction of the slat can be carried out in upstream, in or downstream of the pouring area.
  • upstream and downstream refer to the meaning of scrolling of the preform 5.
  • the slat 6 is then driven by the facing material 1 and the conveyor belt 7.
  • the hydraulic outlet and the hardening of the plaster composition 2 takes place then throughout the movement of the preform 5, indicated by the arrows A.
  • the upper face 401 of the slat 6, that is to say that intended to come into contact with the material of facing 1 (see figure 1), can be at least partially coated with an adhesive allowing it to adhere to the facing material 1, especially when the introduction of the slat is carried out upstream of the pouring area.
  • the slat 6 is removed before cutting the preform 5.
  • the hardness of the preform 5 is sufficient to that the slat 6 can be removed without deforming the preform 5 and without the plaster composition 2 coming fill the space or thinning 8 (figure 3) left by removing the batten 6.
  • the removal of the slat 6 can be carried out according to any suitable way.
  • this fall may have place, for example, in the space between two rollers of the conveyor belt system which, in general, is not continuous throughout the production line, but is formed by several mats driven by rollers between which there are free spaces.
  • the removal of the slat 6 can also be done, at the by means of a blade or a brush (not shown) scraping the underside of the facing material 1 to which the slat 6 adheres to a suitable place, for example example, in the space between two rollers mentioned in previous paragraph.
  • the preform 5 continues to move, still driven by the carpet carrier 7 and curing the composition of plaster 2 continues.
  • the cutting device is adjusted by so that the knives 9 and 9bis cut the preform 5 approximately in the middle of the thinning 8.
  • each thinning 8 depends on the slat dimensions 6.
  • the latter is generally a parallelepiped whose thickness is generally between 0.5 and 4 mm, preferably between 1.5 and 4 mm. Its width is generally between 5 and 20 cm and its length is approximately equal to the width of the material facing 1.
  • the width of the batten 6 is less than that of the facing material 1, in particular, when longitudinal strips are used (called in English "tape").
  • the material of the slats 6 does not matter, from the as long as it allows these slats to resist the weight of the preform thickness 5 which is above each slat 6. It can therefore be a plastic material, wood, metal, cardboard, etc. presenting good wear resistance and stability over time.
  • the process which has just been described complements of a known process for manufacturing plasterboard having two thinned longitudinal edges. This last generally provides for the installation of a band, usually plastic, usually called “Tape" on each longitudinal side of the carpet transporter 7.
  • a band usually plastic
  • hydraulic 11 as illustrated in FIG. 5 having, in addition to its two thinned transverse edges 10, two edges longitudinal 25 thinned, making a total of four edges thinned.
  • the length of the plasterboard produced depends of course the speed of movement of the mat carrier and the frequency of cutting operations.
  • the frequency of cutting operations is generally directly related to the frequency of introduction of slats, because we generally seek to obtain plates having two thinned transverse edges.
  • the method according to the invention is very flexible, because to change the length of the plates manufactured, it just change the frequency of introduction slats.
  • Figure 6 is shown part of a binder-based plate production line hydraulics implementing the method according to the invention.
  • a slat store 20 formed of a horizontal rectangular surface 21 from the corners from which rise vertically and parallel, four angular pieces 22, in the form of an angle iron and facing each other, so as to frame a stack of slats 23.
  • this slatted magazine 20 is such that it can store a high number of slats 23 (see also Figures 7 and 8).
  • the horizontal surface 21 of the slat magazine 20 is supported by feet 24.
  • first batten 23 At the level of the first batten 23, that is to say that located at the bottom of the stack, are arranged in parallel two cylinders 26, which are oriented so as to extract the first batten 23 from the stack by pushing and dragging it to an incline 27 consisting of a downwardly inclined surface 28 and a rim 29 at its lower part to retain the slat which has just been extracted and guide it later.
  • a jack 31 is arranged parallel to the longitudinal axis of the plane inclined 27, so that the actuation of this cylinder 31 can give an impulse to the slat which comes to be extracted from the slat store 20.
  • the slat as well propelled can then move by sliding parallel to the longitudinal axis of the inclined plane 27, whose rim 29 guides it, towards a second inclined plane 32 which extends the first inclined plane 27, on the side transverse opposite side 30.
  • means 402 are provided, for example between the first inclined plane 27 and the second inclined plane 32, to coat with adhesive at least partially the upper face 401 of the slats 23.
  • These means 402 can be constituted, for example, by a brush 402 located above a slat 23, when this slat is on the first inclined plane 27. The displacement of the slat 23 of the first inclined plane 27 towards the second inclined plane 32 allows the brush 402 at least partially coat the upper face 401 of the batten 23 of an adhesive which then allows it to adhere to the facing material.
  • the second inclined plane 32 also consists an inclined surface 33 provided with a rim 34 at its lower part. It further comprises a stop 35 at its end opposite to the jack 31, this stop being generally consisting of a pneumatic shock absorber and being intended to put an end to the displacement of the batten propelled by the jack 31.
  • the rim 34 is provided with openings 36 opposite which are arranged two cylinders 37 oriented so as to propel the batten positioned on the second inclined plane 32 upwards of the inclined surface 33.
  • the first inclined plane 27 and the second plane tilted 32 are supported by feet, respectively, 38 and 39.
  • a flat surface 40 is provided parallel to the surface 23, between the latter and the first inclined plane 27 to horizontally support a slat extracted from the slatted magazine 20 before its descent on the surface inclined 28 of the first inclined plane 27.
  • the height of feet 24, 38 and 39 is chosen so a slat positioned on the second inclined plane 32 is at a height lower than that of the preform 5.
  • the length of the second inclined plane 32 is at least equal to that of lath 23, i.e. at least equal to, and preferably greater than, the width of the preform 5.
  • the slats are arranged otherwise than by stacking in the store at slats. They can for example be arranged side by side coast or according to any appropriate provision their allowing to be extracted individually from the store at slats.
  • the production line according to the invention comprises usually electronic means that control its function and allow, if necessary, to enslave between them the implementations of different operations.
  • Electronic means provide that after the introduction of a slat under the preform by actuation of the jacks 27, the jack 31 is actuated to introduce a new batten on the second plane inclined 32, then the cylinders 26 are actuated to introduce another slat on the first inclined plane 27, and so on.
  • Electronic means can vary the frequency of these operations to reduce or increase the length of the plasterboard with edges thinnings produced.
  • the means 20 to 22, 24 to 39 and 402 which come to be described can be combined into a device according to the invention.
  • the main advantage of such a device is that it can be installed near a manufacturing line classic hydraulic binder-based plates with which he can then cooperate in order to implements the method according to the invention.
