Abstract

The rotating head comprises a predetermined number of blades being supported by a blade carrier arm (3), the latter being integral with the shaft (1). The blades are arranged on a vertical axis in suitably inclined positions, a fact which permits to carry out the automatic coating of the surface of the material by means of every type of material based on marble, stone and the like by means of every type of putty.

Description

Cette invention concerne la construction d'une tête roulante pourvue de spatules inclinées et orientables sur leur propre axe vertical, pour le mastiquage automatique des surfaces des matériaux pierreux au moyen de n'importe quel type de mastic, aussi bien de type cimentaire que résineux.This invention relates to the construction of a rolling head provided with inclined spatulas and orientable on their own vertical axis, for the automatic chewing of the surfaces of stony materials by means of any type of sealant, both cementitious and resinous.

Il existe plusieurs dispositifs pour l'étalement du béton et d'autres matériaux similaires. La publication FR-A-2.485.597, correspondant au préambule de la revendication 1 qui montre l'invention, se réfère à titre d'exemple à un dispositif pour l'étalement d'un matériau de remplissage, par exemple du béton. Le dispositif en question est pourvu d'une pièce rotative bougeant sur un plan horizontal, pour l'étalement au moyen d'une truelle.There are several devices for spreading concrete and other similar materials. The publication FR-A-2,485,597, corresponding to the preamble of claim 1 which shows the invention, refers by way of example to a device for spreading a filling material, for example concrete. The device in question is provided with a rotating part moving on a horizontal plane, for spreading by means of a trowel.

Les publications DE-A-2733419, FR-A-1195455, DE-A-2035465 et US-A-3130653 aussi se réfèrent à l'étalement du béton et de produits similaires.The publications DE-A-2733419, FR-A-1195455, DE-A-2035465 and US-A-3130653 also refer to the spreading of concrete and similar products.

On sait que la technique actuelle fournit la possibilité de mastiquer des surfaces en matériau pierreux seulement lorsque ce mastiquage est effectué au moyen d'un liant à base de ciment.
Dans le cas de liants résineux on doit employer des dispositifs pourvus de spatules, bougeant de façon alternative aussi bien que rotative.It is known that the current technique provides the possibility of chewing surfaces of stony material only when this chewing is carried out using a cement-based binder.
In the case of resinous binders, devices provided with spatulas must be used, moving alternately as well as rotating.

Dans le premier cas aussi bien que dans le second on devra pourtant utiliser des dispositifs de confinement afin d'éviter l'écoulement du mastic, qui a tendance à échapper à l'action des spatules.In the first case as well as in the second one must however use containment devices in order to avoid the flow of the putty, which tends to escape the action of the spatulas.

On a en effet remarqué que, lorsque une spatule entrainant le mastic passe sur une cavité du marbre, elle y faira entrer une partie du mastic, en effectuant ainsi une action de compactage.It has in fact been noted that when a spatula entraining the putty passes over a cavity of the marble, it will cause part of the putty to enter there, thereby effecting a compacting action.

La partie excédentaire aura tendance à retourner dans les zones où la spatule est déjà passée.The excess part will tend to return to the areas where the spatula has already passed.

Le temps employé par le mastic pour ce mouvement de retour dépendra de la viscosité du mastic même.The time used by the sealant for this return movement will depend on the viscosity of the sealant itself.

Lorsque le mastic a atteint une situation d'équilibre pendant le "temps d'attente", la cavité remplie sera recouverte par une quantité excédentaire de mastic, dont la surface libre aura une forme convexe.When the sealant has reached a state of equilibrium during the "waiting time", the filled cavity will be covered by an excess quantity of sealant, the free surface of which will have a convex shape.

On a remarqué qu'il n'est possible de faire passer une autre spatule sur la cavité sans en modifier le dégré de remplissage, que lorsque cet équilibre a été atteint.It has been noted that it is not possible to pass another spatula over the cavity without modifying the degree of filling, only when this equilibrium has been reached.

En effet, si une spatule devait passer sur la cavité avant que le mastic ait atteint cet équilibre dans la cavité même, une certaine quantité de mastic serait emportée, et la cavité ne serait pas parfaitement remplie.Indeed, if a spatula were to pass over the cavity before the putty reached this balance in the cavity itself, a certain amount of putty would be removed, and the cavity would not be perfectly filled.

Dans le dispositif qui est l'objet de cette invention, les spatules, chacune soutenue par un bras porte-spatule 3 solidaire de l'arbre 1, sont montées dans un arrangement radial, à un certain intervalle l'une par rapport à l'autre. La vitesse de rotation du disque sera telle qu'elle pourra permettre que, une fois remplie une cavité, le passage suivant des spatules ne modifie pas le remplissage correct de la cavité.In the device which is the object of this invention, the spatulas, each supported by a spatula holder arm 3 secured to the shaft 1, are mounted in a radial arrangement, at a certain interval one relative to the other. The speed of rotation of the disc will be such that it can allow, once filled a cavity, the following passage of spatulas does not modify the correct filling of the cavity.

On a aussi remarqué qu'il sera bien que le bord inférieur de la spatule tendant à envoyer le mastic vers l'extérieur soit barbelé, de façon à augmenter la pression spécifique sur la surface à mastiquer.We also noticed that it will be good that the lower edge of the spatula tending to send the putty to the outside is barbed, so as to increase the specific pressure on the surface to be chewed.

Le nombre de tours de la tête roulante dépend du nombre de spatules et de la viscosité du mastic.The number of revolutions of the rolling head depends on the number of spatulas and the viscosity of the putty.

La vitesse de rotation devra evidemment être inférieure en cas de mastics très visqueux, par rapport aux mastics plus fluides. L'invention en objet est ci-dessous décrite en détail à l'aide des dessins joints, dont :

  • la fig.1 (planche 1/2), représente la vue schématique latérale de la tête roulante, partiellement sectionnée.
  • la fig.2 (planche 2/2) représente le profil d'une spatule montée sur le bras porte-spatules, dont on peut voir une partie;
  • la fig.3 représente, en perspective, une spatule aubord barbelé, avec ses dispositifs de bloquage;
  • la fig.4 représente, encore en perspective, une spatule aubord lisse, pourvue de dispositifs de fixation;
  • la fig. 5 représent le schéma d'arrangement de quelques spatules radiales,sur leurs bras porte-spatules.
The rotation speed will obviously have to be lower in the case of very viscous sealants, compared to more fluid sealants. The subject invention is described in detail below using the accompanying drawings, including:
  • fig.1 (board 1/2), shows the schematic side view of the rolling head, partially sectioned.
  • fig.2 (plate 2/2) shows the profile of a spatula mounted on the spatula holder arm, part of which can be seen;
  • Fig.3 shows, in perspective, a spatula barbed edge, with its locking devices;
  • Fig.4 shows, still in perspective, a spatula smooth edge, provided with fixing devices;
  • fig. 5 shows the arrangement diagram of a few radial spatulas, on their spatula arms.

Comme on pourra remarquer, dans la Figure 1 en particulier, la tête roulante est pourvue d'un bras 1, mis en rotation par un motovariateur 2, dont la vitesse est réglée en fonction du diamètre de rotation des spatules 4.As will be seen, in FIG. 1 in particular, the rolling head is provided with an arm 1, rotated by a variable speed drive 2, the speed of which is adjusted as a function of the diameter of rotation of the spatulas 4.

Le motoreducteur 5 provoque, au moyen de la vis 6, le déplacement vertical de la tête par rapport aux guides 7, permettant ainsi le soulevement des bras porte-spatule 3 avec et des spatules 4.The geared motor 5 causes, by means of the screw 6, the vertical displacement of the head relative to the guides 7, thus allowing the lifting of the spatula holder arms 3 with and of the spatulas 4.

Chaque spatule 4 (fig.2) est bloquée entre deux mâchoires 8 et 9, hémicylindriques, retenues par un étau 10 (fig.3) monté sur un bras porte-spatule 3 à l'aide des petits écrous 11 et 12, qui permettant de changer la direction de la spatule par rapport à la direction radiale du bras porte-spatule 3.Each spatula 4 (fig.2) is locked between two semi-cylindrical jaws 8 and 9, held by a vice 10 (fig.3) mounted on a spatula holder arm 3 using small nuts 11 and 12, which allow to change the direction of the spatula with respect to the radial direction of the spatula holder arm 3.

Deux séries de trous 13 et 14, formées par exemple de trois trous chacune, ont été faites sur l'étau (fig.3) afin de permettre le déplacement longitudinal de l'étau 10 dans la direction radiale du bras 3.Two series of holes 13 and 14, formed for example of three holes each, were made on the vice (fig.3) in order to allow the longitudinal movement of the vice 10 in the radial direction of the arm 3.

La direction de chaque spatule peut être changé en sens angulaire grâce à des trous 15 et 16 (fig.5) à travers lesquels on fait passer les écrous 11 et 12 fixant l'étau 10.The direction of each spatula can be changed in an angular direction thanks to holes 15 and 16 (fig. 5) through which the nuts 11 and 12 fixing the vice 10 are passed.

On peut remarquer que, tandis que les spatules 4 de la fig.3 ont un bord barbelé, les spatules de la fig. 4 ont un bord lisse.We can notice that, while the spatulas 4 of fig.3 have a barbed edge, the spatulas of fig. 4 have a smooth edge.

Les spatules 4 aussi bien que les spatules 4' sont montées de façon telle à permettre de les placer dans des directions différentes par rapport à la direction radiale du bras 3, grâce aux rainures à secteur circulaire 15 et 16, qui permettent de changer leur position.The spatulas 4 as well as the spatulas 4 'are mounted in such a way as to allow them to be placed in different directions relative to the radial direction of the arm 3, by virtue of the circular sector grooves 15 and 16, which make it possible to change their position .

En particulier, les spatules 4 devraient être placées de façon à tendre à envoyer le mastic vers l'extérieur, tandis que les spatules 4' tendent à le rapprocher au centre de la tête roulante, dont le sens de rotation est indiqué par la flèche 17.In particular, the spatulas 4 should be placed so as to tend to send the putty outwards, while the spatulas 4 'tend to bring it closer to the center of the rolling head, the direction of rotation of which is indicated by the arrow 17 .

Cela permettra d'éviter que le mastic soit forcé vers l'extérieur ou l'intérieur de la surface à stuquer.This will prevent the sealant from being forced outward or inward from the surface to be stuccoed.

Chaque spatule 4 et 4' est prise entre deux mâchoires hémicylindrlques 8 et 9 qui peuvent être inclinées si nécessaire par rapport au plan de travail 18 (fig.1).
Les goupilles 19 et 20 évitent l'extraction accidentelle des spatules 4 et 4' de l'étau 10.
Evidemment les spatules 4 et 4' s'inclinent pendant le travail en tournant jusqu'à s'appuyer contre le bord de l'étau 10 (voir dessin esquissé de la fig.2). Cela a le but d'exercer une pression constante sur la plaque à travailler.Each spatula 4 and 4 'is taken between two semi-cylindrical jaws 8 and 9 which can be tilted if necessary relative to the work surface 18 (fig. 1).
The pins 19 and 20 prevent accidental extraction of the spatulas 4 and 4 'from the vice 10.
Obviously the spatulas 4 and 4 'tilt during work by turning until they press against the edge of the vice 10 (see sketched drawing in fig. 2). This is to exert constant pressure on the plate to be worked.
