Description

La présente invention concerne un dispositif permettant la manutention automatique de plaques, notamment de circuits imprimés. The present invention relates to a device for the automatic handling of plates, in particular printed circuits.

On sait que, dans les lignes de production de plaques de circuits imprimés, on utilise des dispositifs d'alimentation automatiques des plaques dé- vant être traitées. Généralement, ces dispositifs se présentent sous la forme d'un convoyeur sans fin muni de barrettes transversales, qui délimitent des compartiments séparés dans lesquels les plaques sont disposées sur chant, ce convoyeur étant entraîné par un moteur électrique asservi à un détecteur de présence de plaques pour régler la cadence d'alimentation. Dans de telles machines, les barrettes délimitant les compartiments recevant les plaques, et, par consé- quent, les plaques elles-mêmes, sont toujours perpendiculaires au convoyeur, ce qui permet de transporter les plaques verticalement et de les délivrer horizontalement à la machine de traitement. It is known that, in the production lines for printed circuit boards, automatic feeders are used for the boards to be treated. Generally, these devices are in the form of an endless conveyor provided with transverse bars, which delimit separate compartments in which the plates are arranged on edge, this conveyor being driven by an electric motor controlled by a detector of the presence of plates. to set the feed rate. In such machines, the bars delimiting the compartments receiving the plates, and, consequently, the plates themselves, are always perpendicular to the conveyor, which makes it possible to transport the plates vertically and to deliver them horizontally to the treatment.

Les dispositifs d'alimentation de ce type actuellement disponibles dans le commerce présentent l'inconvénient majeur suivant
Les barrettes entre lesquelles sont disposées les plaques ne sont pas jointives sur tout le parcours du convoyeur, et il arrive que des plaques glissent dans l'interstice séparant deux barrettes, ce qui, bien entendu, perturbe le bon fonctionnement du dispositif, et par conséquent l'alimentation.Feeding devices of this type currently available on the market have the following major drawback
The bars between which the plates are placed are not contiguous over the entire path of the conveyor, and it happens that plates slide in the gap separating two bars, which, of course, disrupts the proper functioning of the device, and consequently food.

Cette invention se propose d'apporter une solution à ce problème, et, à cet effet, elle a pour objet un dispositif pour la manutention automatique de plaques, notamment de circuits imprimés, du type convoyeur sans fin muni de barrettes transversales délimitant des compartiments recevant les plaques, disposées sur chant, ce dispositif étant caractérisé en ce que lesdites barrettes comportent une embase munie de charnons espacés, de manière que les charnons d'une embase viennent se positionner entre les charnons de l'embase de la barrette adjacente, l'assemblage des barrettes étant réalisé à l'aide de broches traversant les charnons respectivement alignés, et l'ensemble ainsi réalisé ayant la configuration d'un convoyeur sans fin. This invention proposes to provide a solution to this problem, and, for this purpose, it relates to a device for the automatic handling of plates, in particular of printed circuits, of the endless conveyor type provided with transverse bars delimiting compartments receiving the plates, arranged on edge, this device being characterized in that said bars comprise a base provided with spaced knuckles, so that the knuckles of a base come to be positioned between the knuckles of the base of the adjacent bar, the assembly of the bars being carried out using pins passing through the respective aligned knuckles, and the assembly thus produced having the configuration of an endless conveyor.

Selon l'invention, le dispositif est entraîné par un moteur à temporisation réglable par minuterie, la transmission du mouvement s'effectuant par l'intermédiaire d'au moins un pignon entraîné par ledit moteur, entre les dents duquel reposent les extrémités des broches d'assemblage des différentes barrettes. According to the invention, the device is driven by a motor with time delay adjustable by timer, the movement being transmitted by means of at least one pinion driven by said motor, between the teeth of which the ends of the pins d '' assembly of the different bars.

Selon l'invention, le guidage des différentes barrettes constituant le convoyeur sans fin est assuré par des glissières latérales, recevant les extrémités des broches d'assemblage des barrettes. According to the invention, the guiding of the different bars constituting the endless conveyor is ensured by lateral slides, receiving the ends of the pins for assembling the bars.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence au dessin annexé, qui en illustre un exemple de réalisation dépourvu de tout caractère limitatif. Sur le dessin
- la Figure 1 est une vue en perspective d'un dispositif selon cette invention
- la Figure 2 est une vue de détail montrant, en élévation latérale, une partie du convoyeur sans fin réalisé par l'assemblage des barrettes selon cette invention ; et,
- la Figure 3 est une vue en plan montrant l'assemblage de deux barrette consécutives.Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawing, which illustrates an embodiment thereof devoid of any limiting character. On the drawing
- Figure 1 is a perspective view of a device according to this invention
- Figure 2 is a detail view showing, in side elevation, part of the endless conveyor produced by the assembly of the bars according to this invention; and,
- Figure 3 is a plan view showing the assembly of two consecutive bars.

En se référant au dessin, on voit que le dispositif selon l'invention se présente sous la forme d'un convoyeur sans fin 10, muni de barrettes transversales 12 qui délimitent des compartiments entre lesquels sont introduites les plaques 14, par exemple des plaques de circuits imprimés, devant être délivrées à une ligne de production. Comme on le voit sur la Figure 1, la concep#tion de ce dispositif est telle qu'il permet de transporter verticalement les plaques 14, et de les délivrer horizontalement. Referring to the drawing, it can be seen that the device according to the invention is in the form of an endless conveyor 10, provided with transverse bars 12 which delimit compartments between which the plates 14 are introduced, for example plates of printed circuits, to be delivered to a production line. As seen in Figure 1, the design of this device is such that it allows the plates 14 to be transported vertically, and to be delivered horizontally.

Selon l'invention, chaque barrette 12 comporte une partie longitudinale de grande longueur 12', constituant la paroi du compartiment 16 recevant les plaques 14, et une embase 12". Chaque embase 12" comporte des charnons espacés, tels que 18, 18', de manière que les charnons d'une embase viennent se positionner entre les charnons de l'embase de la barrette adjacente. L'assemblage des barrettes est réalisé à l'aide de broches transversales, telles que 20, 20', traversant respectivement les charnons alignés des différentes embases. Bien entendu cet assemblage est effectué de façon que l'ensemble ainsi réalisé présente la con figuration d'un convoyeur sans fin 10. According to the invention, each bar 12 has a long longitudinal portion 12 ', constituting the wall of the compartment 16 receiving the plates 14, and a base 12 ". Each base 12" has spaced knuckles, such as 18, 18' , so that the knuckles of a base are positioned between the knuckles of the base of the adjacent bar. The assembly of the bars is carried out using transverse pins, such as 20, 20 ′, passing respectively through the aligned knuckles of the different bases. Of course, this assembly is carried out so that the assembly thus produced has the configuration of an endless conveyor 10.

Sur la Figure 3, on a représenté l'assemblage de deux barrettes consécutives, désignées dans leur ensemble par les références 12a et 12'a. On voit que les charnons, tels que 18'b de la barrette 12b, sont imbriqués entre les charnons 18'a de la barrette 12a, l'assemblage étant réalisé par la broche 20', traversant les charnons alignés 18'a, 18b. De la même façon, les charnons tels que 18'b de la barrette 12b viennent s'imbriquer entre les charnons de la barrette suivante (non représentée), et les charnons tels que 18a de la barrette 12a viennent s'imbriquer entre les charnons de la barrette précédente (non représentée), l'assemblage étant réalisé par la broche 20. In Figure 3, there is shown the assembly of two consecutive bars, designated as a whole by the references 12a and 12'a. We see that the knuckles, such as 18'b of the bar 12b, are nested between the knuckles 18'a of the bar 12a, the assembly being carried out by the pin 20 ', passing through the aligned knuckles 18'a, 18b. In the same way, the knuckles such as 18'b of the bar 12b are nested between the knuckles of the next bar (not shown), and the knuckles such as 18a of the bar 12a are nested between the knuckles of the previous bar (not shown), the assembly being carried out by pin 20.

L'entraînement du convoyeur sans fin réalisé par l'assemblage des différentes barrettes s'effectue, comme connu, à l'aide d'un moteur électrique à temporisation réglable.-Dans l'exemple de réalisation représenté sur le dessin, le moteur entrain un pignon, tel que 22, entre les dents duquel viennent reposer les extrémités des broches, telles que 20, 20'. En outre, le guidage de l'ensemble constitué par les barrettes 12 et leur broche d'assemblage est assuré par des glissières latérales, telles que 24, dans lesquelles coulissent les extrémités des broches, sur lesquelles sont emmanchés des paliers 26 pour réduire les frottements. The drive of the endless conveyor carried out by assembling the different bars is carried out, as known, using an electric motor with adjustable time delay. In the embodiment shown in the drawing, the motor drives a pinion, such as 22, between the teeth of which come to rest the ends of the pins, such as 20, 20 '. In addition, the guide of the assembly constituted by the bars 12 and their assembly pin is ensured by lateral slides, such as 24, in which the ends of the pins slide, on which bearings 26 are fitted to reduce friction. .

De la lecture de la description qui précède, on comprend que l'invention permet de réaliser un dispositif de manutention automatique de plaques, notamment de circuits imprimés, qui présente les avantages suivants - impossibilité, pour les plaques 14 transportées, de glisser entre deux bar
rettes, étant donné que les embases successives de ces barrettes constituent
une surface continue de fond du compartiment délimité entre deux barrettes
pour recevoir les plaques. Cette surface constitue une solution de continuité
au niveau du convoyeur - réalisation d'un dispositif symétrique, pouvant travailler en chargeur
déchargeur,le fait que les barrettes soient symétriques permettant un dé
placement des plaques dans un sens quelconque - possibilité de réaliser un entraînement peu coûteux et fiable, par l'inter
médiaire des broches et de pignons tels que 22 ; - interchangeabilité facile des différentes barrettes.Reading the above description, it will be understood that the invention makes it possible to produce an automatic handling device for plates, in particular printed circuits, which has the following advantages - impossibility, for the plates 14 transported, to slide between two bars
rettes, since the successive bases of these bars constitute
a continuous bottom surface of the compartment delimited between two bars
to receive the plates. This surface constitutes a solution of continuity
at the conveyor - creation of a symmetrical device, able to work as a loader
unloader, the fact that the bars are symmetrical allowing a die
placement of the plates in any direction - possibility of carrying out an inexpensive and reliable drive, via the
middle of spindles and pinions such as 22; - easy interchangeability of the different bars.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représenté, mais qu'elle en englobe toutes les variantes.  It remains to be understood that this invention is not limited to the embodiment described and shown, but that it encompasses all variants thereof.
