Abstract
Description
L'invention est du domaine des techniques du bâtiment, et plus particulièrement du moulage de dalles en béton ou analogue. Elle a pour objet un dispositif pour répartir de manière homogène à l'intérieur d'au moins un moule une dose prédéterminée de béton, en sortie d'un poste mélangeur et doseur de préparation de celui-ci.The invention is in the field of building techniques, and more particularly molding of concrete slabs or the like. She has for object a device to distribute homogeneously inside at least a mold a predetermined dose of concrete, at the outlet of a mixing station and dispenser for preparing the same.
On rappelle que l'on connaít dans le domaine du bâtiment un poste de travail pour le mélange et le dosage du béton, et pour la coulée consécutive d'une dose de béton préparé à l'intérieur d'un moule. Dans sa globalité, ce poste comprend successivement un mélangeur pour la préparation du béton, un doseur pour isoler une quantité déterminée du béton à couler, et un moule de réception de cette dose de béton.Remember that we know in the field of construction a workstation for mixing and dosing concrete, and for subsequent pouring of a dose of concrete prepared inside a mold. Overall, this post successively includes a mixer for the preparation of concrete, a metering device to isolate a specific quantity of concrete to be poured, and a mold reception of this dose of concrete.
Un problème à résoudre réside dans la répartition homogène du béton dosé à l'intérieur du moule lors de sa coulée. Plus précisément et notamment dans le cas de moulage de dalles, il est essentiel que le produit obtenu présente une épaisseur constante. A problem to be solved lies in the homogeneous distribution of the metered concrete inside the mold when it is poured. More specifically and in particular in in the case of molding slabs, it is essential that the product obtained has constant thickness.
De manière courante, la coulée du béton est guidée par des tôles placées de manière à centrer le béton déversé à l'intérieur du moule. Toutefois, ces postes de travail comprennent un jeu de moules de tailles différentes, qui sont utilisés alternativement en fonction des besoins ponctuels. Il en découle qu'il est fréquent que le moule ne soit pas disposé dans l'axe du doseur, et que les tôles, positionnées par rapport à ce dernier, ne guident la coulée de béton que sur une partie seulement du fond du moule.Usually, the concrete pouring is guided by sheets placed so as to center the concrete spilled inside the mold. However, these workstations include a set of molds of different sizes, which are used alternately according to specific needs. It follows it is frequent that the mold is not placed in the axis of the dispenser, and that the sheets, positioned in relation to the latter, guide the pouring of concrete only on part of the bottom of the mold.
Il a donc été proposé d'équiper le moule de moyens pour le secouer afin de répartir le béton qu'il contient. Mais cette solution n'offre pas en soi un résultat satisfaisant pour le moulage de dalles, dont l'épaisseur doit être la plus régulière possible. En outre, il est nécessaire de secouer longuement le moule, au détriment des cadences de fabrication.It has therefore been proposed to equip the mold with means for shaking it in order to distribute the concrete it contains. But this solution does not in itself offer a satisfactory result for the molding of slabs, the thickness of which must be the as regular as possible. In addition, it is necessary to shake the mold, at the expense of production rates.
Le but de la présente invention est de proposer un dispositif destiné à équiper un poste mélangeur et doseur d'un matériau pâteux, béton plus particulièrement, pour répartir de manière homogène le matériau dosé à l'intérieur d'un moule, pour la fabrication de dalles de parement notamment.The object of the present invention is to provide a device intended for equip a mixing and dosing station with a pasty material, concrete more particularly, to distribute the material dosed evenly inside a mold, for the production of facing tiles in particular.
La démarche inventive de la présente invention a consisté dans sa généralité à interposer en sortie du doseur et en amont du moule au moins un godet intermédiaire. Ce godet est aménagé pour recevoir la dose de béton dans une première étape, puis pour être secoué dans une deuxième étape pour répartir de manière homogène le béton qu'il a reçu, puis enfin pour déverser par retournement du godet le béton à l'intérieur du moule.The inventive step of the present invention consisted in its generality to interpose at the outlet of the doser and upstream of the mold at least one cup intermediate. This bucket is arranged to receive the dose of concrete in a first step, then to be shaken in a second step to evenly distribute the concrete it received, then finally to pour by turning the bucket the concrete inside the mold.
II résulte de ces dispositions que le béton est déversé sur la totalité de la surface formant le fond du moule, favorisant sa répartition à l'intérieur de celui-ci. On comprendra toutefois qu'il est néanmoins souhaitable que le moule soit équipé des moyens habituels pour le secouer, en vue d'achever la répartition homogène du béton qu'il contient. On relèvera aussi que grâce à l'invention, le temps réservé à secouer le moule peut être réduit, ce qui permet d'accroítre les cadences de fabrication.It follows from these provisions that the concrete is poured over the whole of the surface forming the bottom of the mold, favoring its distribution inside this one. It will however be understood that it is nevertheless desirable that the mold is equipped with the usual means for shaking it, in order to complete the homogeneous distribution of the concrete it contains. We will also note that thanks to the invention, the time reserved for shaking the mold can be reduced, which allows to increase the production rates.
Le fond du godet est avantageusement incurvé et est bordé par des parois planes d'extrémité, pour favoriser la répartition du matériau dans son volume intérieur lorsqu'il est secoué, préalablement à son retournement, et pour favoriser l'écoulement régulier du béton hors du godet lorsqu'il est retourné.The bottom of the bucket is advantageously curved and is bordered by walls end planes, to favor the distribution of the material in its volume inside when shaken, before it is turned over, and for favor the regular flow of concrete out of the bucket when it is turned over.
Le godet comporte avantageusement au moins un revêtement de sa face intérieure en matière plastique, telle que PVC, dans le cas où celui-ci est en métal par exemple. Ces dispositions visent à offrir une adhérence de la face intérieure du godet qui ne fasse pas obstacle à l'écoulement du béton. De manière analogue pour ce même résultat, le godet peut aussi être globalement fabriqué à partir de cette matière plastique. The bucket advantageously comprises at least one coating of its face plastic interior, such as PVC, if it is metal for example. These provisions are intended to provide grip of the face inside of the bucket which does not obstruct the flow of concrete. Of similarly for this same result, the bucket can also be generally made from this plastic.
Les moyens pour secouer le godet comprennent notamment un organe vibreur auquel il est mécaniquement relié. On comprendra que cet organe vibreur est indifféremment équipé de l'un quelconque au moins des moyens pour sa manoeuvre manuelle et des moyens pour sa manoeuvre motorisée.The means for shaking the bucket include in particular a member vibrator to which it is mechanically connected. It will be understood that this organ vibrator is equally equipped with any one at least of the means for its manual operation and means for its motorized operation.
Les moyens pour retourner le godet comportent de préférence des moyens de réglage de la vitesse de son retournement, afin de déverser la quantité de béton dosée sur une surface du moule d'une largeur plus ou moins grande.The means for turning the bucket preferably comprises means regulating the speed of its overturning, in order to pour the quantity of concrete dosed on a more or less wide width of the mold surface.
L'axe de retournement du godet est longitudinalement étendu le long de celui-ci suivant l'une quelconque des génératrices de la face incurvée formant son fond, pour ajuster la surface correspondante de déversement du béton dans le moule en fonction de sa largeur et de son positionnement transversal à l'intérieur du poste de fabrication.The bucket turning axis is longitudinally extended along this one according to any one of the generatrices of the curved face forming its bottom, to adjust the corresponding discharge surface of the concrete in the mold according to its width and its positioning transverse inside the manufacturing station.
On relèvera que le dispositif est avantageusement pourvu de moyens d'interchangeabilité de la position susvisée de l'axe de retournement du godet, pour le placer selon des besoins ponctuels.It will be noted that the device is advantageously provided with means interchangeability of the above-mentioned position of the turning axis of the bucket, to place it according to specific needs.
La présente invention sera mieux comprise et des détails en relevant
apparaítront, à la description qui va en être faite de formes préférées de
réalisation, en relation avec les figures de la planche annexée, dans
laquelle :
Sur la fig.1, le dispositif de l'invention est destiné à équiper un poste de
fabrication de produits plans en matériau pâteux durcissable, tels que dalles
de béton ou analogues. Ce poste de fabrication comprend un mélangeur 1
du matériau et au moins un doseur 2 du matériau mélangé préalablement à
sa coulée dans un moule 3 qui lui est affecté. On comprendra que ce doseur
2 est indifféremment un doseur pondéral ou un doseur volumétrique connus
de l'art antérieur.In fig.1, the device of the invention is intended to equip a workstation
manufacture of flat products of curable pasty material, such as slabs
of concrete or the like. This manufacturing station includes a mixer 1

le moule 3.The device of the invention constitutes means for distributing so
homogeneous inside the
Ce dispositif comprend dans sa généralité:
On remarquera plus particulièrement sur les fig.2 et fig.3 que le fond 8 du godet est de préférence incurvé et est bordé par des parois planes d'extrémité 9,9'.It will be noted more particularly in FIGS. 2 and FIG. 3 that the bottom 8 of the bucket is preferably curved and is bordered by flat walls 9.9 'end.
Sur la fig.2, le godet 4 est articulé en retournement par l'intermédiaire d'un
arbre 7 auquel il est lié en rotation, de préférence à la face inférieure de son
fond 8. Cet arbre de retournement 7 est relié à l'une de ses extrémités aux
moyens 6 de retournement du godet 4 pour son entraínement en rotation, et
à son autre extrémité aux moyens 5 pour secouer le godet 4 pour sa mise en
vibration.In fig. 2, the
On remarquera sur la fig.4 diverses variantes de réalisation, illustrées en
traits interrompus représentant des positions respectives de l'arbre 7 sur le
godet 4. Par exemple et en se reportant sur la fig.5, l'arbre de retournement
7 est étendu le long de l'axe médian du godet 4, tandis que sur la fig.6,
l'arbre de retournement 7 est décalé par rapport à cet axe médian.Note in fig.4 various alternative embodiments, illustrated in
broken lines representing respective positions of the

supérieur à 90°, pour rendre certain sa vidange.It will be noted that the angle A of reversal of the
Pour un même dispositif, le godet 4 est avantageusement équipé de moyens
pour placer l'arbre de retournement 7 suivant l'une quelconque de ces
positions, en fonction de la largeur et de la position transversale du moule 3
ponctuellement utilisé.For the same device, the
Selon un exemple préféré de réalisation, et en se reportant à la fig.7, les
moyens 6 de retournement du godet 4 comprennent un mécanisme à
pignons 10,10',10" d'entraínement en rotation du godet 4 autour d'un axe
longitudinal 7 de retournement. Le mécanisme à pignons 10,10',10" est
manoeuvrable par un organe moteur 11, tel qu'un vérin hydraulique ou
analogue d'entraínement d'une crémaillère 10". According to a preferred embodiment, and with reference to FIG. 7, the
Sur cet exemple, et indifféremment quant aux dispositions précédentes, les
moules 3,3' sont en pluralité, au nombre de deux sur l'exemple illustré. Le
dispositif comporte une batterie de godets 4,12 et 4',12' affectés à un moule
3,3' respectif. On remarquera que pour un même moule 3 ou 3', plusieurs
godets 4,12 ou 4',12' lui sont avantageusement affectés pour favoriser la
répartition de la dose de béton à l'intérieur du moule. On comprendra donc
que les godets en batterie 4,12 et 4',12' sont affectés à l'unité au moins à un
moule respectif 3 ou 3 ', et que plusieurs moules 3 et 3' peuvent être
simultanément remplis à partir de quantités dosées respectives de béton.In this example, and regardless of the previous provisions, the
