Abstract
Description
La présente invention est relative à un couvercle de protection pour cuve telle que, par exemple, une cuve de pétrin. The present invention relates to a protective cover for a tank such as, for example, a kneading tank.
Actuellement, les cuves de pétrin sont pourvues d'un couvercle empêchant l'accès à la cuve lorsque le bras de pétrin est en action. Currently, the kneader tanks are provided with a cover preventing access to the tank when the kneader arm is in action.
S'agissant d'une industrie alimentaire, les couvercles sont réalisés en acier inoxydable et ils sont soit relevables soit pivotants. As it is a food industry, the covers are made of stainless steel and can either be lifted or swiveled.
L'expérience a montré que ces couvercles présentaient divers défauts. Parmi ceux-ci il faut citer le poids, la difficulté de nettoyage surtout pour les couvercles pivotants et le prix de revient élevé en raison de la matière utilisée. Experience has shown that these covers have various defects. Among these are the weight, the difficulty of cleaning especially for the swivel covers and the high cost price due to the material used.
Le couvercle de l'invention, qui remédie à ces inconvénients, est remarquable en ce qu'il est obtenu à l'aide d'un tube ou tout autre profil, métallique ou autre, enroulé, dans un plan, à spires non jointives. The cover of the invention, which overcomes these drawbacks, is remarkable in that it is obtained using a tube or any other profile, metallic or otherwise, wound, in a plane, with non-contiguous turns.
L'invention sera mieux comprise par la description qui va suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement, sur lesquels
La figure 1 est une vue en élévation-coupe d'un couvercle relevable, conforme à l'invention, en place sur une cuve,
La figure 2 est une vue de dessus de la figure 1
Les figures 3 et 4 sont des vues analogues à celles 1 et 2, l'invention étant appliquée à un couvercle en deux parties pouvant pivoter dans un plan horizontal.The invention will be better understood from the following description made with reference to the accompanying drawings by way of indicative example only, in which
FIG. 1 is a view in elevation-section of a lifting lid, in accordance with the invention, in place on a tank,
Figure 2 is a top view of Figure 1
Figures 3 and 4 are views similar to those 1 and 2, the invention being applied to a cover in two parts which can pivot in a horizontal plane.
En se reportant aux figures 1 et 2, on voit que 1 est une cuve telle qu'une cuve de pétrin mécanique dans laquelle plonge le bras usuel 2. Referring to FIGS. 1 and 2, it can be seen that 1 is a tank such as a mechanical kneading tank in which the usual arm 2 plunges.
Selon l'invention, on dispose au-dessus de la cuve un couvercle 3 constitué par l'enroulement dans un plan -et à spires non jointives, d'une barre profilée pleine ou tubulaire. According to the invention, there is disposed above the tank a cover 3 constituted by the winding in a plane -and non-contiguous turns, of a solid or tubular profiled bar.
Le couvercle 3 comporte à sa périphérie une patte 4 rendue solidaire d'un arbre 5. The cover 3 has at its periphery a tab 4 made integral with a shaft 5.
L'arbre 5 est articulé sur le bâti (non représenté)-du pétrin. The shaft 5 is articulated on the frame (not shown) -the kneader.
Le cas échéant, pour maintenir toutes les spires dans le même plan, celles-ci sont réunies par une barre 6 dont la fixation par soudage est très facile à réaliser. If necessary, to keep all the turns in the same plane, these are joined by a bar 6 whose fixing by welding is very easy to perform.
La barre 6 s'étend au-delà de la périphérie du couvercle en une extension 7 constituant une poignée de manoeuvre. The bar 6 extends beyond the periphery of the cover in an extension 7 constituting an operating handle.
De la façon connue, des moyens peuvent être prévus pour que le relevage du-couvercle interrompe la rotation du bras de pétrin 2. In known manner, means can be provided so that the raising of the cover interrupts the rotation of the kneading arm 2.
Les figures 3 et 4 illustrent un mode de réalisation appliqué à un couvercle dont les deux parties 8 et 9 peuvent pivoter dans des plans parallèles autour d'un axe IO commun à celui de la cuve 1. La fixation des deux parties du couvercle s'effectue comme celle des couvercles usuels. Figures 3 and 4 illustrate an embodiment applied to a cover, the two parts 8 and 9 of which can pivot in parallel planes around an axis IO common to that of the tank 1. The fixing of the two parts of the cover is performs like that of the usual covers.
Naturellement, le couvercle, lorsqu'il obture la cuve, doit laisser subsister un espace suffisant pour permettre le passage du bras 2. Naturally, the cover, when it closes the tank, must leave sufficient space to allow the passage of the arm 2.
Dans le cas du couvercle relevable, ce résultat est obtenu en interrompant les spires extrêmes comme montré sur la figure 2. In the case of the liftable cover, this result is obtained by interrupting the extreme turns as shown in FIG. 2.
Dans le cas du couvercle pivotant, ce résultat est obtenu de façon encore plus simple, en augmentant le rayon d'enroulement des spires de chacun des parties 8 et 9 au droit du passage du bras. In the case of the pivoting cover, this result is obtained even more simply, by increasing the winding radius of the turns of each of the parts 8 and 9 in line with the passage of the arm.
Bien entendu la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes, matières et dimensions. Of course the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes, materials and dimensions.
