Abstract

In a method for stacking arcuately curved roof tiles on a trolley, after they have been dried, for firing in a tunnel kiln, the tiles are put in parallel piles on a refractory base resting on the trolley. Astride a set of piles, e.g. three piles, is placed a trestle-like support made of refractory material. This support then takes another similar set of parallel piles, which are in turn engaged by another trestle support resting on the first support. The final set of piles can rest on the top trestle and do not need any separate enclosure. Since the top layer of tiles is unenclosed, less supports are needed than in known methods, and the cost of heating these is saved.

Description

La présente invention a pour objet un procédé qui simplifie sensiblement l'opération de chargement et de déchargement des tuiles canal (tuiles courbes) et des tuiles ordinaires sur les chariots introduits dans les fours tunl et dans les autres types de fours pour produits en terre cuite, ce procédé prévoyant l'utilisation de casiers renverses ou disposés en portiques au lieu de caisses
il est actuellement connu d'introduire les tuiles canal (tuiles courbes) et les tuiles ordinaires dans les fours de cuisson au moyen de chariots sur lesquels elles sont empilées par groupes en tant disposées dans des casiers en matière refractaire, généralement superposes au nombre de trois, avec les bords diriges vers le haut, dans le but d'éviter une charge excessive sur les tuiles qui, juste séchées mais non encore cuites, ne pressentent pas une résistance suffisante pour une telle charge.
The subject of the present invention is a process which appreciably simplifies the operation of loading and unloading channel tiles (curved tiles) and ordinary tiles on the trolleys introduced in tunl ovens and in other types of ovens for terracotta products. , this process providing for the use of inverted lockers or those arranged in gantry cranes instead of boxes
it is currently known to introduce channel tiles (curved tiles) and ordinary tiles in baking ovens by means of trolleys on which they are stacked in groups as arranged in refractory racks, generally three in number , with the edges pointing upwards, in order to avoid excessive loading on the tiles which, just dried but not yet fired, do not feel sufficient resistance for such a loading.

Cette opération d'empilage est compliquée parce qu'elle doit entre effectuée en introduisant chaque groupe de tuiles canal ou de tuiles ordinaires dans le casier correspondant par une manoeuvre de de chargement des casiers à partir du chariot de remplissage des casiers avec des tuiles canal ou des tuiles ordinaires seches a cuire et ensuite de rechargement du chariot avec les casiers remplis. Tout cela nécessite le recours a une installation très sophistiquée et, en conséquence, très onereuse.  This stacking operation is complicated because it must be carried out by introducing each group of channel tiles or ordinary tiles into the corresponding bin by a maneuver for loading the compartments from the compartment filling trolley with canal tiles or ordinary dry baking tiles and then reloading the cart with the trays filled. All this requires the use of a very sophisticated installation and, consequently, very expensive.

Il est en outre nécessaire d'utiliser un nombre de casiers régal au nombre des groupes à empliler, ce qui enQ-raine une immobilisation de capital notable en liaison avec le prix élevé des casiers en matière réfractaire. It is also necessary to use a number of lockers equal to the number of groups to be stacked, which results in a considerable capital immobilization in connection with the high price of the refractory lockers.

L2invention a pour but d'eviter les inconvenients mentionnes précédemment et concerne à cet effet un procédé du type ci dessus caractérisé en ce qu'on dispose en portiques sur le plan situé en dessous les casiers en matière réfractaire qui soutiennent chaque groupe de produits à cuire, apres QOi on dispose les groupes de produits sur ces casiers ers supprimant ainsi toute la série de casiers correspondant à la couche supérieure de produits à enfourner, ce qui entraine une réduction sensible du nombre des casiers utilisés et procure une grande facilité d'empilage des produits sur le plan de base et sur les casiers utilisés en dessous.  L2invention aims to avoid the drawbacks mentioned above and to this end relates to a process of the above type characterized in that there are porticoes on the plan located below the refractory racks which support each group of products to be cooked , after QOi, the product groups are placed on these racks, thus eliminating the whole series of racks corresponding to the upper layer of products to be placed in the oven, which results in a significant reduction in the number of racks used and provides great ease of stacking the products on the base plan and on the lockers used below.

Avec l'adoption du procédé conforme a l'invention, contrairement à ce qui a lieu avec les procédés connus, les tuiles canal ou les tuiles ordinaires sont disposées en groupes sur le plan de charge, on introduit ensuite les casiers qui agissent dans ce cas comme supports des groupes de tuiles canal ou de tuiles situés au-dessous, ce qui constitue une simplification sensible de l'opération d'empilage et de déchargement. On a également la possibilité de réaliser des machines d'empilage et de déchargement moins coûteuses et qui permettent le triage et la formation de paquets pour le transport du produit cuit. With the adoption of the process according to the invention, contrary to what takes place with the known processes, the channel tiles or the ordinary tiles are arranged in groups on the load plane, the compartments which act in this case are then introduced. as supports for the groups of channel tiles or tiles located below, which constitutes a significant simplification of the stacking and unloading operation. There is also the possibility of making stacking and unloading machines which are less expensive and which allow sorting and forming of packages for transporting the cooked product.

La mise en application du procédé. conforme à l'invention permet en outre de supprimer toute la série de casiers supérieurs. En effet les groupes de produits de la série supérieure s'appuient simplement sur les casiers situés audessous qui chevauchent comme des portiques les groupes inférieursde produi-ts à cuire et présentent un plan d'appui parfait au dessus de ces produits. The implementation of the process. according to the invention also makes it possible to eliminate the entire series of upper compartments. Indeed, the groups of products of the upper series are simply based on the racks below which overlap like gantry cranes the lower groups of products to be cooked and have a perfect support surface above these products.

On réduit ainsi le nombre des casiers à utiliser pour chaque chariot, par exemple de un tiers si les produits sont disposés en trois couches comme ctest normalement le cas pour les chariots destinés å un tel service. The number of compartments to be used for each trolley is thus reduced, for example by a third if the products are arranged in three layers as is normally the case for the trolleys intended for such a service.

L'invention sera mieux comprise en regard de la description ci-après et des dessins annexés représentant un exemple de réalisation de l'invention, dessins dans lesquels
- la figure 1 est une vue en élévation schématique du plan de chargement d'un chariot destiné a enfourner des tuiles canal et des tuiles empilées suivant le procédé conforme- à l'invention,
- la figure 2 représente le chariot en vue latérale.
The invention will be better understood with reference to the description below and to the accompanying drawings showing an embodiment of the invention, drawings in which
FIG. 1 is a diagrammatic elevation view of the loading plane of a trolley intended to bake channel tiles and tiles stacked according to the process in accordance with the invention,
- Figure 2 shows the carriage in side view.

Suivant le procédé conforme à l'invention, les tuiles canal (tuiles courbes) ou les tuiles ordinaires à cuire sont empilées et déchargées par groupes, par exemple en trois files parallèles, sur le plan du chariot 1. Le chargement est effectué au moyen de plaques réfractaires de base 2 sur lesquelles sont successivement disposés les casiers 3 également en matière réfractaire, montés comme des portiques pour permettre l'appui sur eux d'un nouveau groupe de produits sur lequel est disposé un nouveau casier 4 pour soutenir la couche située audessus. According to the process according to the invention, the channel tiles (curved tiles) or the ordinary tiles to be fired are stacked and unloaded in groups, for example in three parallel rows, on the plane of the carriage 1. The loading is carried out by means of basic refractory plates 2 on which the racks 3 are successively arranged also in refractory material, mounted like gantries to allow the support on them of a new group of products on which is placed a new rack 4 to support the layer situated above .

Un troisième groupe de produits à cuire est disposé directement sur le plan supérieur du casier 4. A third group of products to be cooked is placed directly on the upper plane of rack 4.

On notera qutavec le procédé conforme à I'invention, chaque groupe de produits est disposé sur le plan de la plaque de base 2 ou sur le plan des casiers situés endessous par une simple manoeuvre, de dép8t. La même chose est valable pour les casiers reposant sur le plan inférieur servant uniquement d'appui pour les groupes de produits situés audessus. It will be noted that with the process according to the invention, each group of products is arranged on the plane of the base plate 2 or on the plane of the compartments located below by a simple operation, of dep8t. The same is valid for the compartments resting on the lower plane serving only as support for the groups of products located above.

Tout celà entratne une simplification dans la réalisation des appareils destinés aux opérations d'empilage et de déchargement. All this leads to a simplification in the production of devices intended for stacking and unloading operations.

On notera en outre qu'en utilisant le procédé conforme à l'invention, il suffit, dans l'exemple de réalisation représenté, de mettre en oeuvre deux couches de casiers au lieu de trois, comme cela était nécessaire dans les procédés utilisés jusqu'à maintenant. On effectue des économies notables d'immobilisation de capital pour la même quantité de produits enfournés. It will also be noted that, by using the process according to the invention, it suffices, in the embodiment shown, to use two layers of racks instead of three, as was necessary in the processes used up to now. Significant capital immobilization savings are made for the same amount of product loaded.

Si l'on pense que pour un four de produits en terre cuite, les casiers en matière réfractaire onéreuse constituent une grande immobilisation de capital, on voit immédiatement l'avantage sensible que l'on obtient. If we think that for an oven of terracotta products, the expensive refractory baskets constitute a great immobilization of capital, we immediately see the significant advantage that we obtain.

En outre, la plus faible masse de matière réfractaire qui doit être chauffée à chaque fois dans les fours de cuisson et qui se refroiti ensuite à la sortie de ces fours entrasse également une économie sensible sur le plan énergétique et, par conséquent sur le prix global de l'opération de cuisson. In addition, the lower mass of refractory material which must be heated each time in the baking ovens and which then cools down at the outlet of these ovens also hides a significant saving in terms of energy and, consequently, in the overall price. of the cooking operation.

Bien entendu, les détails constructifs de détail tels que les dimensions, le nombre des groupes empilés sur le chariot ou élément similaire peuvent prendre des formes et des aspects différents de ceux qui ont été représentés à titre d'exemple non limitatif. Of course, the constructive details of detail such as the dimensions, the number of the groups stacked on the carriage or the like can take forms and aspects different from those which have been shown by way of nonlimiting example.
