Description

Dispositif de singularisation et d'orientation de pièces élémentaires Device for singularization and orientation of elementary parts
La présente invention concerne un dispositif de singularisation et d'orientation de pièces élémentaires.The present invention relates to a device for singularization and orientation of elementary parts.
Dans de nombreux secteurs industriels des processus de fabrication prévoient l'assemblage de plusieurs pièces élémentaires pour former un objet.In many industrial sectors, manufacturing processes provide for the assembly of several elementary parts to form an object.
Les pièces élémentaires (par exemple des éléments en matière plastique de boîtiers électriques) fournies en vrac sont acheminées vers un poste d'assemblage.The elementary parts (for example plastic elements of electrical boxes) supplied in bulk are sent to an assembly station.
Or, l'opération d'assemblage exige que les diverses pièces élémentaires soient présentées à ce poste d'assemblage de manière unitaire et suivant une orientation prédéterminée permettant le déroulement de l'opération d'assemblage.However, the assembly operation requires that the various elementary parts be presented at this assembly station in a unitary manner and in a predetermined orientation allowing the assembly operation to take place.
Il est possible de faire réaliser, manuellement, ces opérations de singularisation et d'orientation des pièces unitaires par un opérateur.It is possible to have these singularization and orientation operations for the unit parts carried out manually by an operator.
Lorsque l'on veut automatiser ces opérations, on a le plus souvent recours à l'utilisation de bols vibrants. Ces bols présentent plusieurs inconvénients importants.When we want to automate these operations, we most often use the use of vibrating bowls. These bowls have several significant drawbacks.
En premier lieu, ce sont des équipements extrêmement coûteux. En outre, leur fonctionnement ne donne pas entièrement satisfaction. En effet, les bols vibrants ne fonctionnent correctement que lorsque les pièces unitaires sont dimensionnellement parfaites. Or, on constate que de nombreuses pièces, notamment des pièces de moulage, présentent des bavures. Bien que ces bavures soient sans incidence sur le bon fonctionnement de ces pièces, elles perturbent le fonctionnement des bols vibrants ce qui en réduit leur rendement.First, they are extremely expensive equipment. In addition, their operation is not entirely satisfactory. Indeed, the vibrating bowls only work properly when the unit parts are dimensionally perfect. However, we find that many parts, including molding parts, have burrs. Although these burrs do not affect the proper functioning of these parts, they disturb the operation of the vibrating bowls which reduces their performance.
Enfin, les bols vibrants sont conçus et dimensionnés spécifiquement pour un type de pièces particulières et ne présentent donc pas de flexibilité permettant de les utiliser pour des pièces présentant une autre géométrie.Finally, the vibrating bowls are designed and sized specifically for a particular type of part and therefore do not have the flexibility to use them for parts with another geometry.
En outre, il est connu, par le document US 4 690 266, un dispositif présentant deux convoyeurs à bande déposés côté à côte et fonctionnant en sens opposés. Ce dispositif permet d'orienter des articles qui arrivent un par un à partir d'une trémie. Par ailleurs, le document US 5 788 053 montre un dispositif de séparation utilisant deux convoyeurs disposés côte à côte et fonctionnant en sens opposés.In addition, it is known, from document US 4 690 266, a device having two belt conveyors deposited side by side and operating in opposite directions. This device makes it possible to orient articles which arrive one by one from a hopper. Furthermore, document US Pat. No. 5,788,053 shows a separation device using two conveyors arranged side by side and operating in opposite directions.
Le document WO 01/83340 décrit un dispositif complexe qui, selon certaines formes de réalisation, utilise des éléments de redirection en vue de ne réaliser qu'une orientation de pièces.The document WO 01/83340 describes a complex device which, according to certain embodiments, uses redirection elements in order to achieve only an orientation of parts.
La présente invention a pour but de proposer un dispositif d'acheminement de pièces élémentaires qui permet de singulariser et d'orienter des pièces élémentaires. Un autre but de l'invention est que ce dispositif soit d'un faible coût et qui puisse être facilement adapté à des pièces de géométries différentes.The object of the present invention is to propose a device for conveying elementary parts which makes it possible to single out and orient elementary parts. Another object of the invention is that this device is of low cost and which can be easily adapted to parts of different geometries.
A cet effet, ce dispositif comprend au moins un convoyeur à bande présentant :To this end, this device comprises at least one belt conveyor having:
- une partie inclinée par rapport à l'horizontal, muni d'un déflecteur de singularisation, disposé transversalement par rapport au convoyeur, ménageant entre son extrémité et le bord du convoyeur une ouverture correspondant à la plus petite dimension de la pièce élémentaire et, d'une goulotte incurvée s'étendant latéralement sur le bord de la partie inclinée opposé à celui recevant le déflecteur de singularisation. - une partie horizontale munie d'au moins un déflecteur d'orientation disposé transversalement contre lequel vient en appui la pièce élémentaire pour se placer dans une orientation prédéterminée.- a part inclined with respect to the horizontal, provided with a singling deflector, arranged transversely with respect to the conveyor, providing between its end and the edge of the conveyor an opening corresponding to the smallest dimension of the elementary part and, d 'a curved chute extending laterally on the edge of the inclined part opposite to that receiving the singling deflector. - A horizontal part provided with at least one orientation deflector arranged transversely against which abuts the elementary part to place itself in a predetermined orientation.
Ce dispositif permet de réaliser une première phase de singularisation, c'est-à-dire d'isolation d'une pièce parmi une population de pièces déposées en vrac, puis d'orienter cette pièce dans une position prédéterminée et ce sans mettre en œuvre de dispositif complexe de l'état de la technique utilisant plusieurs convoyeurs disposés côte à côte.This device makes it possible to carry out a first phase of singularization, that is to say of isolating a part from a population of parts deposited in bulk, then to orient this part in a predetermined position and this without implementing of complex device of the prior art using several conveyors arranged side by side.
Selon une forme de réalisation préférée, ce dispositif comprendAccording to a preferred embodiment, this device comprises
- un convoyeur à bande de singularisation supportant le déflecteur de singularisation et- a singularization belt conveyor supporting the singularization deflector and
- un convoyeur à bande d'orientation horizontal placé en bout du convoyeur de singularisation.- a horizontal orientation belt conveyor placed at the end of the singularization conveyor.
Selon une possibilité avantageuse, le convoyeur à bande d'orientation supporte deux déflecteurs, le premier permettant le régulation des pièces et le second assurant l'orientation des pièces. La régulation des pièces par le premier des déflecteurs du convoyeur d'orientation permet de contrôler le flux des pièces en provenance du convoyeur de singularisation.According to an advantageous possibility, the orientation belt conveyor supports two deflectors, the first allowing the regulation of the parts and the second ensuring the orientation of the parts. The regulation of the pieces by the first of the deflectors of the orientation conveyor makes it possible to control the flow of the pieces coming from the singularization conveyor.
Selon une caractéristique avantageuse, une goulotte incurvée s'étend latéralement sur le bord du convoyeur de singularisation opposé à celui recevant le déflecteur de singularisation.According to an advantageous characteristic, a curved chute extends laterally on the edge of the singling conveyor opposite to that receiving the singling deflector.
De préférence, chacun des déflecteurs est susceptible d'être orienté par rapport à la direction de défilement de leur convoyeur respectif.Preferably, each of the deflectors is capable of being oriented relative to the direction of travel of their respective conveyor.
De plus, les déflecteurs présentent une structure télescopique présentant deux éléments tubulaires coulissant l'un dans l'autre.In addition, the deflectors have a telescopic structure having two tubular elements sliding one inside the other.
Selon une disposition préférentielle, le convoyeur de singularisation est orienté d'environ 30° par rapport à l'horizontal.According to a preferred arrangement, the singularization conveyor is oriented about 30 ° relative to the horizontal.
En outre, l'extrémité inférieure du convoyeur de singularisation plonge dans un réservoir dans lequel les pièces élémentaires sont déversées. Pour sa bonne compréhension, l'invention est décrite en référence au dessin ci-annexé représentant à titre d'exemple non limitatif une forme de réalisation de l'invention.In addition, the lower end of the singling conveyor plunges into a tank into which the elementary parts are poured. For a good understanding, the invention is described with reference to the attached drawing showing by way of nonlimiting example an embodiment of the invention.

La figure 2 représente le dispositif en vue de dessus; La figure 3 représente en perspective un convoyeur de singularisation;Figure 2 shows the device in top view; Figure 3 shows in perspective a singularization conveyor;
La figure 4 représente un second convoyeur d'orientation;Figure 4 shows a second orientation conveyor;
La figure 5 montre le fonctionnement du convoyeur.Figure 5 shows the operation of the conveyor.
Comme on peut le voir sur la figure 1 , le dispositif comprend deux convoyeurs à bande, un convoyeur de singularisation 1 et un convoyeur d'orientation 2.As can be seen in FIG. 1, the device comprises two belt conveyors, a singularization conveyor 1 and an orientation conveyor 2.
Le convoyeur de singularisation 1 comprend une bande sans fin, entraînée par des rouleaux, inclinée d'environ 30° par rapport à l'horizontal. Son extrémité la plus basse plonge dans un réservoir 3 destiné à recevoir une population de pièces élémentaires.The singularization conveyor 1 comprises an endless belt, driven by rollers, inclined by approximately 30 ° relative to the horizontal. Its lowest end plunges into a reservoir 3 intended to receive a population of elementary parts.
Un déflecteur 5 est disposé transversalement sur le convoyeur de singularisation 1.A deflector 5 is arranged transversely on the singularization conveyor 1.
Ce déflecteur 5 est constitué d'une structure télescopique fixée sur l'un des bords du convoyeur. La fixation de ce dernier permet d'en régler l'orientation par rapport au convoyeur 2. Le déflecteur 5 comprend deux éléments 7,8 coulissants l'un dans l'autre, si bien que sa longueur peut être réglée. La longueur du déflecteur 5 est telle qu'une ouverture 11 est ménagée entre l'extrémité du déflecteur 5 et le bord du convoyeur. Cette ouverture étant égale à la plus petite dimension de la pièce. Sur le bord du convoyeur 1 opposé à celui recevant le déflecteur 5, le convoyeur reçoit une goulotte 9 qui est sensiblement en face du déflecteur.This deflector 5 consists of a telescopic structure fixed to one of the edges of the conveyor. The fixing of the latter makes it possible to adjust the orientation with respect to the conveyor 2. The deflector 5 comprises two elements 7.8 sliding one inside the other, so that its length can be adjusted. The length of the deflector 5 is such that an opening 11 is formed between the end of the deflector 5 and the edge of the conveyor. This opening being equal to the smallest dimension of the part. On the edge of the conveyor 1 opposite to that receiving the deflector 5, the conveyor receives a chute 9 which is substantially opposite the deflector.
Cette goulotte 9 est constituée d'une tôle incurvée qui s'étend latéralement le long du convoyeur. La fonction de cette goulotte apparaîtra plus loin. Le second convoyeur, à savoir le convoyeur d'orientation 2, qui présente également une bande sans fin, est disposé en bout de l'extrémité la plus haute du convoyeur de singularisation 1.This chute 9 consists of a curved sheet which extends laterally along the conveyor. The function of this chute will appear below. The second conveyor, namely the orientation conveyor 2, which also has an endless belt, is arranged at the end of the highest end of the singularization conveyor 1.
Le convoyeur d'orientation 2 est disposé horizontalement.The orientation conveyor 2 is arranged horizontally.
Comme on peut le voir sur la figure 4, plusieurs déflecteurs 12 sont disposés transversalement par rapport à la direction de défilement du convoyeur.As can be seen in FIG. 4, several deflectors 12 are arranged transversely with respect to the direction of travel of the conveyor.
Ces déflecteurs 12 présentent une structure similaire à celle du déflecteur 5 présent sur le convoyeur de singularisation 1. Ils peuvent ainsi être orientés par rapport au sens de défilement du convoyeur et leur longueur peut être modifiée.These deflectors 12 have a structure similar to that of the deflector 5 present on the singularization conveyor 1. They can thus be oriented relative to the direction of travel of the conveyor and their length can be modified.
Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.
Une quantité de pièces est introduite dans le réservoir de pièces 3 situé en amont du convoyeur de singularisation 1.A quantity of parts is introduced into the parts reservoir 3 located upstream of the singularization conveyor 1.
Le convoyeur 1 est mis en fonctionnement ce qui entraîne un défilement de sa bande sans fin. Les pièces sont donc acheminées vers le déflecteur 5.The conveyor 1 is put into operation, which causes its endless belt to run. The parts are therefore routed to the deflector 5.
Grâce à l'inclinaison du convoyeur de singularisation, les pièces arrivent en butée contre le déflecteur 5 sur une seule épaisseur, en d'autres termes des pièces superposées sur des pièces en contact de la bande retombent dans la partie la plus basse du réservoir 3.Thanks to the inclination of the singularization conveyor, the parts come into abutment against the deflector 5 over a single thickness, in other words parts superimposed on parts in contact with the strip fall back into the lowest part of the tank 3 .
Le défilement continu de la bande produit une accumulation de pièces contre le déflecteur 5, ce dernier ne s'étendant pas sur la totalité de la largeur du convoyeur, les pièces peuvent s'échapper de manière unitaire par l'ouverture délimitée par l'extrémité du déflecteur 5 et le bord du convoyeur 1. L'excédent de pièces est poussé sur la goulotte 9 et, par gravité, retombe dans la partie inférieure du réservoir 3. Cet excédent de pièces qui retombe dans la partie inférieure crée une dynamique dans la zone de l'ouverture qui prévient la formation de bourrage ou blocage.The continuous running of the strip produces an accumulation of parts against the deflector 5, the latter not extending over the entire width of the conveyor, the parts can escape in a unitary manner through the opening delimited by the end of the deflector 5 and the edge of the conveyor 1. The excess of parts is pushed onto the chute 9 and, by gravity, falls back into the lower part of the tank 3. This excess of parts which falls back into the lower part creates a dynamic in the area of the opening which prevents the formation of jamming or blockage.
Les pièces sont donc acheminées selon une orientation quelconque, une par une, vers le convoyeur d'orientation.The parts are therefore routed in any orientation, one by one, to the orientation conveyor.
Celui-ci peut présenter deux déflecteurs 12 comme cela est représenté à la figure 2, ou trois déflecteurs 12 comme cela est représenté à la figure 4.This may have two deflectors 12 as shown in FIG. 2, or three deflectors 12 as shown in FIG. 4.
Les pièces arrivant sur le convoyeur d'orientation sont entraînées par le défilement du tapis contre un premier déflecteur d'orientation.The parts arriving on the orientation conveyor are driven by the movement of the belt against a first orientation deflector.
Selon l'orientation de la pièce, il se forme un couple de forces dû au défilement de la bande qui, lorsqu'il excède le couple de frottement entre le déflecteur et la pièce, conduit à un basculement de la pièce. Celle-ci se place contre le déflecteur selon sa plus grande dimension comme le montre la figure 5.Depending on the orientation of the part, a couple of forces is formed due to the movement of the strip which, when it exceeds the friction torque between the deflector and the part, leads to a tilting of the part. This is placed against the deflector according to its largest dimension as shown in Figure 5.
La succession des déflecteurs 12 d'une part, permet de s'assurer que les pièces se placent toutes selon une même orientation, d'autre part, en accélérant la vitesse de défilement, permet d'augmenter la distance séparant deux pièces élémentaires. Ainsi, en agissant sur la vitesse de défilement du tapis, il est possible de contrôler l'espace entre deux pièces en fonction de l'opération finale que doit subir chaque pièce.The succession of deflectors 12 on the one hand, makes it possible to ensure that the parts are all placed in the same orientation, on the other hand, by accelerating the speed of travel, makes it possible to increase the distance separating two elementary parts. Thus, by acting on the speed of movement of the belt, it is possible to control the space between two parts as a function of the final operation which each part must undergo.
Il s'agit d'un avantage important du dispositif puisqu'il permet un acheminement pièce par pièce alors qu'un bol vibrant achemine des pièces en continu, chaque pièce poussant la pièce qui la précède immédiatement. Or ce principe d'acheminement induit des chevauchements, des bourrages et des blocages.This is an important advantage of the device since it allows piece-by-piece routing while a vibrating bowl routes pieces continuously, each piece pushing the piece that immediately precedes it. However, this routing principle induces overlaps, jams and blockages.
En se réfèrent à la figure 2, on peut voir que le déflecteur 12 situé du coté du convoyeur d'orientation s'étend transversalement par rapport sur une longueur ménageant à son extrémité une ouverture correspondant à la plus petite dimension de la pièce élémentaire. Ce déflecteur permet de réguler la cadence avec laquelle les pièces parviennent au déflecteur de d'orientation 12 suivant.Referring to Figure 2, we can see that the deflector 12 located on the side of the orientation conveyor extends transversely with respect to a length leaving at its end an opening corresponding to the smallest dimension of the elementary part. This deflector makes it possible to regulate the rate with which the parts reach the following orientation deflector 12.
L'invention fournit ainsi un dispositif permettant de singulariser et d'orienter les pièces élémentaires présentant une structure peu coûteuse et paramétrable en fonction de la géométrie des pièces à acheminer, cette propriété étant obtenue par le réglage de la longueur et de l'orientation des déflecteurs par rapport à la bande des convoyeurs.The invention thus provides a device making it possible to single out and orient the elementary parts having an inexpensive structure and configurable as a function of the geometry of the parts to be conveyed, this property being obtained by adjusting the length and orientation of the deflectors relative to the conveyor belt.
Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite à titre d'exemple non limitatif mais qu'elle en embrasse au contraire toutes les formes de réalisation.It goes without saying that the invention is not limited to the embodiment described by way of nonlimiting example but that, on the contrary, it embraces all of the embodiments.
Ainsi, le dispositif peut comporter en aval du convoyeur d'orientation des doigts de détrompage permettant d'orienter la pièce dans un sens particulier si nécessaire. L'orientation peut également être réalisé par des plots d'orientation qui réalisent une orientation dans le sens vertical. Thus, the device can comprise downstream of the orientation conveyor polarizing fingers making it possible to orient the part in a particular direction if necessary. Orientation can also be achieved by orientation pads which provide orientation in the vertical direction.
