Abstract
Machine comprenant un support (2) d'objet (11) à ébavurer mobile vers une bande sans fin (3) abrasive et montée souplement pour se déformer et envelopper une portion de contour de l'objet quand celui-ci est appliqué sur elle. Le procédé consiste à ébavurer ainsi successivement les portions de contour de l'objet, qui ne subit de rotation qu'entre deux ébavurages et après avoir reculé son support. Il est ainsi possible d'éviter les variations d'effort de la bande sans fin (3). L'invention est particulièrement utile pour les objets en matériau tendre tels que les assiettes avant leur cuisson.Machine comprising a support (2) for the object (11) to be deburring movable towards an endless abrasive belt (3) and flexibly mounted to deform and wrap a portion of the contour of the object when the latter is applied to it. The process consists in thus successively deburring the contour portions of the object, which only undergoes rotation between two deburring and after having moved back its support. It is thus possible to avoid variations in the force of the endless belt (3). The invention is particularly useful for objects made of soft material such as plates before they are cooked.

MACHINE ET PROCEDE D'EBAVURAGE D'OBJETS MACHINE AND METHOD FOR DEBURRING OBJECTS
EN MATERIAU TENDREIN SOFT MATERIAL
DESCRIPTIONDESCRIPTION
L'invention est relative à une machine et à The invention relates to a machine and to
un procédé d'ébavurage d'objets en matériau tendre. a process for deburring objects made of soft material.
Elle peut en particulier être utilisée entre le pressage du kaolin pour former les assiettes et la cuisson qui durcit le kaolin donne l'assiette en porcelaine: des bavures qu'il est nécessaire It can in particular be used between pressing the kaolin to form the plates and the cooking which hardens the kaolin gives the porcelain plate: burrs that are necessary
d'éliminer sont produites par le pressage. to eliminate are produced by pressing.
La nature tendre et friable du kaolin cru empêche de recourir aux procédés usuels d'usinage On utilise généralement une sorte de râpe pressée sur le contour de l'assiette par un ressort, et l'assiette est placée sur un support tournant qui fait défiler tout son contour devant la râpe, dont la force d'application est suffisante pour arracher la bavure mais trop petite The soft and crumbly nature of raw kaolin prevents us from resorting to the usual machining processes. We generally use a sort of grater pressed on the contour of the plate by a spring, and the plate is placed on a rotating support which scrolls everything its outline in front of the grater, whose application force is sufficient to tear off the burr but too small
pour déformer le bord de l'assiette. to distort the edge of the plate.
Ce procédé donne satisfaction pour les contours circulaires mais est inutilisable pour les autres et notamment pour les contours polygonaux, car le ressort exagérément comprimé par les portions d'angles de contour exerce une plus grande force sur eux et les écorne La tendreté du kaolin limite donc l'application de ce genre de dispositifs à pressage élastique, sinon très employé dans l'industrie pour This process is satisfactory for circular contours but is unusable for others and in particular for polygonal contours, because the spring excessively compressed by the portions of contour angles exerts a greater force on them and the corns The tenderness of the kaolin therefore limits the application of this kind of elastic pressing devices, otherwise very widely used in industry for
toutes sortes de matériaux à usiner. all kinds of materials to be machined.
Comme la petitesse des séries et les variations de dimensions interdisent de recourir à un ébavurage par robot, on doit accepter l'ébavurage manuel qui n'est pourtant guère moins coûteux, si bien que le prix de ces assiettes à la forme plus originale As the smallness of the series and the variations in dimensions prohibit resorting to deburring by robot, one must accept manual deburring which is however hardly less expensive, so much so that the price of these plates in the more original form
restreint la clientèle.restricts clientele.
On chercha à proposer un mode d'ébavurage très simple, efficace et bon marché en concevant L'invention. Le procédé est original en ce qu'il consiste à imposer à l'objet des rotations discontinues et à presser l'objet par des portions successives entre les rotations sur une bande abrasive défiante montée apte We tried to offer a very simple, efficient and inexpensive deburring method when designing the invention. The process is original in that it consists in imposing on the object discontinuous rotations and in pressing the object by successive portions between the rotations on a defective abrasive strip mounted suitable
à se déformer pour envelopper les portions de l'objet. to deform to wrap the portions of the object.
Chaque portion de l'objet comporte souvent un côté de Each portion of the object often has a side of
contour polygonal.polygonal outline.
Une machine adaptée à l'emploi de ce procédé comprend une bande abrasive défilante, un support de la bande et un support de l'objet, les supports étant mutuellement mobiles pour éloigner l'objet de la bande et le rapprocher d'elle, le support d'objet étant apte à faire tourner l'objet pour en présenter des portions successives devant la bande, la bande étant reliée à son support par une liaison élastique qui permet de la déformer quand elle est touchée par l'objet La liaison élastique peut être constituée par une poulie de tension de la bande reliée au support de bande par un ressort et éventuellement par un levier articulé au support de bande et sur lequel la poulie est montée folle. A machine adapted to the use of this method comprises a moving abrasive strip, a support for the strip and a support for the object, the supports being mutually movable to move the object away from the strip and bring it closer to it, the object support being able to rotate the object to present successive portions in front of the strip, the strip being connected to its support by an elastic connection which allows it to deform when it is touched by the object The elastic connection can be constituted by a belt tension pulley connected to the band support by a spring and possibly by a lever articulated to the band support and on which the pulley is mounted idly.
Une description plus complète de l'invention A more complete description of the invention
va maintenant être donnée à titre purement illustratif en référence aux figures 1 et 2, qui représentant la machine d'ébavurage dans ses deux positions principales. La machine est en vue de dessus On peut y discerner un support de bande 1 et un support d'objet 2 mobile par rapport au précédent selon un mouvement de translation alternative de gauche à droite sur les figures Le support de bande 1 porte une bande sans fin 3 recouverte de particules abrasives, qui défile sans cesse sous l'action d'une poulie motrice 4 et que deux poulies montées folles 5 et 6 maintiennent en forme de triangle isocèle sur la figure 1, le plus grand côté étant situé entre les poulies folles 5 et 6 Celle-ci est montée à l'extrémité d'un levier 7 dont l'autre extrémité est articulée au support de bande I alors que celle-là est fixe Un ressort 8 ramène le levier 7 will now be given purely by way of illustration with reference to Figures 1 and 2, which show the deburring machine in its two main positions. The machine is in top view We can discern there a band support 1 and an object support 2 movable compared to the previous one according to an alternative translational movement from left to right in the figures The band support 1 carries a band without end 3 covered with abrasive particles, which constantly scrolls under the action of a drive pulley 4 and that two idler mounted pulleys 5 and 6 maintain in the form of an isosceles triangle in FIG. 1, the largest side being located between the pulleys crazy 5 and 6 This one is mounted at the end of a lever 7 whose other end is articulated to the band support I while this one is fixed A spring 8 brings back the lever 7
dans la position de tension de la bande sans fin 3. in the tensioning position of the endless belt 3.
Le support d'objet 2 coulisse dans une rainure 9 creusée dans le support de bande 1 IL porte un plateau 10 tournant autour d'un axe vertical et qui porte une assiette 11 sensiblement carrée et dont les côtés 12 sont légèrement incurvés et saillants vers l'extérieur ou convexes Ils sont réunis par des petits côtés de raccordement 13 Les dispositifs moteurs utilisés pour mouvoir le support d'objet 2 et le plateau 10 ne sont pas représentés L'assiette 11 est plaquée sur le plateau 10 par son poids, par une The object support 2 slides in a groove 9 hollowed out in the band support 1 IT carries a plate 10 rotating around a vertical axis and which carries a plate 11 substantially square and whose sides 12 are slightly curved and projecting towards the exterior or convex They are joined by short connection sides 13 The motor devices used to move the object support 2 and the plate 10 are not shown The plate 11 is pressed onto the plate 10 by its weight, by a
succion ou par tout autre moyen connu. suction or by any other known means.
Des buses 14 de soufflage d'air sont placées Air blowing nozzles 14 are placed
au fond de la rainure 9, dans un creux sous celle-ci. at the bottom of the groove 9, in a hollow under the latter.
Elles sont alimentées par une source d'air comprimé commune par des tuyaux souples et installées de manière démontable sur une armature 15 choisie pour permettre de les aligner avec les côtés 12 Les buses 14 sont découvertes sur la figure 1 et contribuent à arracher ou à repousser de côté la plus grande partie de la bavure du côté 12 qui les surplombe La finition d'ébavurage est toutefois accomplie par la bande sans fin 3: le support d'objet 2 est déplacé vers elle They are supplied by a common compressed air source by flexible pipes and installed in a removable manner on a frame 15 chosen to allow them to be aligned with the sides 12 The nozzles 14 are discovered in FIG. 1 and help to tear off or repel from the side most of the burr on the side 12 which overhangs them The deburring finish is however accomplished by the endless band 3: the object support 2 is moved towards it
jusqu'à ce que le côté 12 qui lui fait face la touche. until the side 12 facing it touches it.
La bande sans fin 3 se courbe alors en rapprochant les poulies folles 5 et 6, ce que le levier 7 et le ressort 8 permettent, et jusqu'à ce que le côté 12 soit enveloppé par la bande sans fin 3 La bavure, représentée en tirets, est alors retirée en un temps très bref inférieur à une seconde La figure 2 The endless band 3 then bends by bringing the idler pulleys 5 and 6 together, which the lever 7 and the spring 8 allow, and until the side 12 is enveloped by the endless band 3 The burr, shown in dashes, is then removed in a very short time less than a second Figure 2
représente la position d'ébavurage. represents the deburring position.
On revient ensuite à la figure 1 en reculant le support d'objet 2 Le plateau 10 est alors tourné pour placer un autre côté 12 ou 13 face à la bande sans fin 3, et c'est ce côté 12 ou 13 qui subira l'ébavurage ensuite Le ressort 8 ramène la poulie folle 6 à sa position initiale de tension et maintient la tension de We then return to FIG. 1 by moving the object support 2 backwards. The plate 10 is then turned to place another side 12 or 13 facing the endless belt 3, and it is this side 12 or 13 which will undergo the then deburring The spring 8 returns the idler pulley 6 to its initial tension position and maintains the tension of
la bande sans fin 3.the endless band 3.
L'ébavurage est donc discontinu et accompli portion par portion des assiettes 11 Il n'en est pas moins efficace et rapide On peut appliquer cette invention à toutes les pâtes frittées en matériau Deburring is therefore discontinuous and accomplished portion by portion of the plates 11 It is nonetheless efficient and rapid This invention can be applied to all sintered doughs made of material
tendre et à tous les contours convexes. tender and with all convex contours.
Il est utile de programmer les mouvements de translation du support d'objet 2 pour que la tension de La bande sans fin 3 soit la même pour tous les côtés 12 ou 13 quelle que soit leur longueur quand ils sont appliqués sur elle Un capteur de position est donc avantageusement ajouté à la machine pour évaluer ces mouvements, qu'il est ensuite facile d'asservir Les positions appropriées du support d'objet 2 pendant l'ébavurage peuvent être fournies par l'expérience ou It is useful to program the translational movements of the object support 2 so that the tension of the endless belt 3 is the same for all sides 12 or 13 regardless of their length when they are applied to it A position sensor is therefore advantageously added to the machine to evaluate these movements, which it is then easy to control. The appropriate positions of the object support 2 during deburring can be provided by experience or
des essais préliminaires.preliminary tests.
Les buses 14 pourraient être placées à un endroit de la chaîne de fabrication entre la presse et la présente machine; le placement correct des assiettes 11 déjà parfaitement ébavurées sur le support The nozzles 14 could be placed at a location in the production line between the press and the present machine; the correct placement of the plates 11 already perfectly deburred on the support
d'objet 2 serait plus facile.object 2 would be easier.
