Definitions

  • the present invention relates to improvements in support devices products having to pass through a baking oven.
  • Certain dry products such as tiles, for example, do not have, after drying, sufficient mechanical strength to be placed directly on the means which transport them through an oven where they are cooked.
  • the present invention belongs to this technical field but implements supports made up of elements that are assembled so that they can receive the cooking products.
  • the support according to the invention consists of the assembly of three elements: feet, longitudinal bars carried by said feet and cross members placed on the bars across these, intended to carry the products to be cooked and is characterized in that the feet are shaped so that they can be stacked on top of each other so that the supports can be used individually or in stacks.
  • the support for the following products to be cooked consists of the assembly of three elements which are: feet 1, longitudinal bars 2 which are carried by the feet 1 and crosspieces 3 which are laid across the bars 2.
  • feet 1 which can be placed either at the ends of the bars 2, as shown in FIG. 1, or at a certain distance from said ends, as shown in Figures 5 and 6.
  • the bars 2 are carried by the feet 1, being positioned in housings of these.
  • the feet 1 are provided with housings opening on their upper face constituted by notches 10, the bars 2 are then placed in these notches 10.
  • Said housings may also not open into the upper face of the feet and be in the form of blind or through holes drilled in the thickness of the foot.
  • FIG. 7 shows an alternative embodiment in which the housings consist of 120 through holes drilled in the feet 101.
  • At least two housings 10, 120 in each leg 1, 101 it follows that at least two housings 10, 120 in each leg 1, 101, but there may be have more than two.
  • the feet have more than two housings 10, 120, it is possible to constitute a support comprising more than two bars, or have several spacings in order to adapt the spacing between the bars to products that need to be cooked.
  • the feet 1 are shaped so that they can be stacked on top of each other so as to form vertical stacks of supports comprising as many stages of bars 2 and crosspieces 3 as there are feet 1 stacked on top of each other.
  • the products to be cooked 4 which, in the example shown in Figure 8, are interlocking tiles.
  • the support composed by an assembly of feet 1, bars 2, crosspieces 3 bearing products 4 can be placed on the floor 50 of a wagon 5, fitted with wheels 51, rolling on rails 52.
  • the implementation of the supports according to the invention makes it possible to constitute stacks supports with as many floors as desired and adapt the height of stacking in the oven section, or use only one support when using a single-layer oven having a low passage section.
  • the assemblies of three elements according to the invention form assemblies which are manipulable at one time by known manipulation means.
  • gripping means 11 can be, as shown, a part projecting in the middle of the height of a foot 1, this projecting part also being able to be well placed at the base or at the top of the foot 1.
  • this projecting part instead of a part in projection we can practice in the mass of the foot a recess in which can penetrate a finger carried by handling tongs.
  • FIGS. 9 to 11 illustrate different alternative embodiments of the feet 1.
  • the feet shown in Figure 9 are those of Figures 1 to 7.
  • the notches 10 have a section which is a semicircle and are arranged on both sides of each foot 1 so that when the feet 1 are placed one on the other, the notches 10 of the upper face of a foot 1 form with the notches 10 of the lower face of the foot 1, which is placed above, a cylinder in which is fitted the cylindrical bar 2.
  • the feet 1 each have five notches 10 on each of their faces, upper and lower. This therefore spares five cylindrical housings so that one can have up to five bars 2 on these feet.
  • these five housings will be used to have fewer than five bars so as to adapt the spacing between said bars to the dimensions of the products to be cooked, we have shown by way of example in FIG. 10, an arrangement using three bars 2.
  • each bar 2 is located in two notches 10 formed one in the lower foot 1, the other in the upper foot 1, the feet 1 are held in position against any lateral sliding.
  • the notch 10 can also be constituted by a groove having a depth greater than the outside diameter of the bars 2 of so that the bars 2 of a lower leg 1 no longer project into the notches 10 of the upper foot 1 and no longer constitute stops preventing lateral sliding stacked feet.
  • the invention is not limited to the case where the bars 2 are of circular section as well as the bottoms of the notches 10: as illustrated in FIGS. 12 and 13, the bars 2 can have any desired section such as square, triangular or else rectangular or even polygonal.
  • each leg 1 has, at the bottom of the notch 10, which receives the bar 2, a additional notch 110 which receives a flange 20 whose section corresponds to that of the additional notch 110 in order to accommodate it.
  • the notch 110 is slightly larger than the collar 21 to absorb the effects of heat expansion.
  • the sleepers 3 are simply placed on the bars 2 and can have any suitable form to effectively support the products to be cooked, they constitute the laying plan of the products to be cooked and are shaped so as to provide the support needed for each type of product.
  • the crosspieces 31 and 32 are U-section bars which include at least one notch 30 which is housed on the upper part of a bar 2, the notch 30 having a shape corresponding to that of said bar 2.
  • each cross member 31 and 32 does not have that a single notch 30 which engages on a bar 2, the cross 31/32 resting on the other side flat on the other bar so that it can slide slightly on it in case of expansion due to heat.
  • the cross members 32 of FIG. 4 have a greater height than that of the cross members 31 in Figure 3 which allows better positioning of the tiles 4 as seen on the figure 6.
  • the crosspieces 3 may not be bars but be plates 34 as this is shown in Figure 6.
  • These trays 34 can, as seen in the Figure 6, have a section corresponding to that of the bars 31 and be fixed to their end to a bar 32.
  • the invention is not limited to this form particular of tray 34, the important thing being that each tray comprises at least a notch 30 adapted to engage on a bar 2 for its positioning.
  • the crosspieces 131 and 132 are of different shapes. These crosspieces 131, 132 can be arranged on the bars 102 being more or less separated from each other so as to be positioned at best depending on the products to be cooked.
  • the cross member 132 arranged to the left of a cross-member or plate 131 may be further from it than that which is placed to the right of said plate 131 so as to allow passage to a wall extending vertically down from the product to be cooked.
  • the sleepers being placed on the bars, it's easy to move them relative to them to reposition them and thus adapt the support to the shape of the product to be cooked.
  • crosspieces 3 it is still possible to provide for the use of crosspieces 3 by turning them around of one of their three axes.
  • the adaptation of the support installation plan to the products to be cooked is carried out in selecting the crosspieces presenting the supports adapted to the products to be cooked and by positioning on the bars with the correct orientation and spacing.
  • We can this effect either keep the sleepers previously used by spreading them or bringing them together, possibly after having made them revolve around one of their three axes X, Y, Z in order to position them so that their face faces the top shows the supports adapted to the products to be cooked. It is also possible to replace the sleepers with other sleepers with the necessary supports.
  • Figures 20 to 23 show by way of nonlimiting examples different variants of making sleepers 3 and / or plates 34.
  • the cross 3 intended to rest on three bars has a central notch 30 and rests flat on each side on the other two bars 2.
  • the cross-member 3 is similar to those of FIGS. 1 to 6 but, the bars 2 being of square section, the notch 30 is also of square section.
  • the bars 2 being of square section as on Figure 21, the two sides 33 of the square section notch 30 may constitute internal (fig. 22) or external (fig. 23) stops.
  • the different elements feet 1, bars 2 and crosspieces 3 are made of materials refractory or fire resistant.
  • the crosspieces 3 are made of cordierite, silicon carbide or even steel; the bars 2 of refractory material with high mechanical strength such as silicon carbide ; the feet 1 may be of lesser refractory material quality therefore cheaper.
