Abstract

The marker consists of a receiver (20) for a stack (23) of flat supporting plates (22) which are moved by gravity along the receiver, a positioner (18) and a marking pencil (9), and an ejector (26) for the marked plate. The marking pencil is positioned beneath the receiver so that it marks the under surface of the bottom plate (22A) in a stack. The direction of movement of the plate is inclined relative to the vertical, and the receiver, which is in the form of an open-bottomed trough, extends over only part of the plate stack perimeter, e.g. along two adjacent sides.

Description

La présente invention concerne les dispositifs de marquage de supports plans.The present invention relates to marking devices of flat supports.

De manière habituelle, ce type de dispositif comporte un boítier d'alimentation vertical au sein duquel les supports sont empilés. Les parois intérieures de ce boítier entourent l'ensemble de la périphérie des supports, en vue de leur maintien latéral.Usually, this type of device includes a vertical power box in which the supports are stacked. The interior walls of this case surround the entire periphery of the supports, with a view to their lateral support.

Un ensemble de convoyage permet de diriger le support inférieur de la pile vers une tête de marquage. Une fois marqué, le support considéré est expulsé de la zone de marquage par l'arrivée du support suivant extrait de la partie inférieure de la pile.A conveyor assembly allows to direct the support bottom of the stack toward a marking head. Once marked, the support considered is expelled from the marking area by the arrival of the following support extracted from the lower part from the stack.

L'ensemble des supports marqués peut être empilé au sein d'une goulotte de réception, ou bien encore éjecté en vrac.All marked supports can be stacked within from a receiving chute, or else ejected in bulk.

Un tel dispositif présente cependant des inconvénients en ce sens qu'il est constitué par un nombre élevé d'éléments mécaniques. Or, ces derniers ne sont pour la plupart pas adaptés à des supports de tailles différentes, de sorte qu'il s'avère nécessaire de changer la majorité de ces éléments lorsqu'on modifie la taille des supports à marquer.However, such a device has drawbacks in meaning that it is made up of a large number of elements mechanical. However, most of these are not suitable for supports of different sizes, so that is necessary to change the majority of these elements when changing the size of the supports to be marked.

De plus, il est indispensable d'opérer un guidage précis des supports le long des éléments de convoyage de manière à en assurer un positionnement satisfaisant. Enfin, chaque support doit être immobilisé par bridage au niveau de la zone de marquage, afin de garantir une qualité de marquage satisfaisante. Ceci est réalisé par l'intermédiaire d'organes de bridage relativement complexes augmentant le coût de l'ensemble du dispositif de marquage.In addition, it is essential to operate a precise guidance supports along the conveyor elements so as to ensure satisfactory positioning. Finally, each support must be immobilized by clamping at the level of the marking, in order to guarantee a satisfactory quality of marking. This is achieved by means of clamping devices relatively complex increasing the cost of the whole marking device.

Afin de pallier l'ensemble des inconvénients de l'art antérieur évoqués ci-dessus, l'invention se propose de réaliser un dispositif de marquage dont l'encombrement soit faible, qui soit constitué d'un nombre limité d'éléments mécaniques et qui garantisse une qualité de marquage satisfaisante.In order to overcome all the drawbacks of art mentioned above, the invention proposes to achieve a marking device with a small footprint, which is made up of a limited number of mechanical elements and which guarantee a satisfactory quality of marking.

A cet effet, l'invention a pour objet un dispositif de marquage de supports plans, notamment de plaques, comprenant des moyens de réception d'une pile formée par lesdits supports, ces derniers se déplaçant par gravité le long de ces moyens de réception selon une direction de déplacement, un crayon de marquage, des moyens de positionnement d'un support à marquer par rapport au crayon de marquage, et des moyens d'éjection du support marqué, caractérisé en ce que le crayon de marquage est disposé sous les moyens de réception et est adapté pour marquer la face inférieure du support inférieur de la pile.To this end, the invention relates to a device for marking of flat supports, in particular of plates, comprising means for receiving a stack formed by said supports, these moving by gravity along these means of reception in a direction of travel, a pencil marking, means for positioning a support to be marked relative to the marking pen, and means for ejecting the marked support, characterized in that the marking pencil is arranged under the receiving means and is suitable for marking the underside of the lower battery support.

Selon d'autres caractéristiques de l'invention :

  • la direction de déplacement est inclinée par rapport à la verticale, et les moyens de réception s'étendent uniquement sur une partie du périmètre des supports empilés ;

  • les moyens d'éjection du support marqué comprennent un organe mobile destiné à pousser le support selon une direction d'éjection perpendiculaire à la direction de déplacement, la course de cet organe mobile étant supérieure aux dimensions du support selon cette direction d'éjection ;
  • le dispositif comprend des surfaces en regard définissant un chemin de guidage dudit support marqué durant sa phase d'éjection.
According to other characteristics of the invention:
  • the direction of movement is inclined relative to the vertical, and the receiving means extend only over part of the perimeter of the stacked supports;
  • the supports are polygonal, in particular quadrilaterals, and the receiving means extend only on two adjacent sides of the supports;
  • the receiving means comprise a chute open downwards;

  • the means for positioning the support to be marked comprise bearing surfaces of at least two opposite edges of this support;
  • the distance between the bearing surfaces is adjustable;
  • the means for positioning the support to be marked comprise a weight added to the upper support of the stack;

  • the device comprises facing surfaces defining a guide path for said marked support during its ejection phase.

L'invention a également pour objet un procédé de marquage de supports plans, notamment de plaques, dans lequel on dispose les supports selon une pile au sein des moyens de réception, on fait se déplacer par gravité les supports empilés le long de ces moyens de réception, on positionne un support à marquer par rapport à un crayon de marquage, on marque ce support et on éjecte ce support marqué, caractérisé en ce qu'on marque la face inférieure du support inférieur de la pile.The subject of the invention is also a method of marking of flat supports, in particular of plates, in which one has the supports according to a stack within the reception means, makes the supports stacked along gravity move these reception means, a support is positioned to be marked by compared to a marking pencil, we mark this support and we ejects this marked support, characterized in that it marks the underside of the lower battery support.

L'invention va être décrite ci-dessous, en référence aux dessins annexés, donnés uniquement à titre d'exemple non limitatif et dans lesquels :

  • la figure 1 est une vue schématique en perspective d'un dispositif de marquage conforme à l'invention ;
  • la figure 2 est une vue de dessus, selon l'axe de la goulotte, d'une partie du dispositif représenté à la figure 1 ;
  • les figures 3 et 4 sont des vues en coupe selon la ligne III-III à la figure 2, représentant deux phases successives du fonctionnement du dispositif conforme à l'invention et
  • la figure 5 est une vue en coupe selon la ligne V-V à la figure 3.
The invention will be described below, with reference to the accompanying drawings, given solely by way of non-limiting example and in which:
  • Figure 1 is a schematic perspective view of a marking device according to the invention;
  • Figure 2 is a top view, along the axis of the chute, of a part of the device shown in Figure 1;
  • FIGS. 3 and 4 are sectional views along line III-III in FIG. 2, representing two successive phases of the operation of the device according to the invention and
  • FIG. 5 is a sectional view along the line VV in FIG. 3.

Le dispositif de marquage conforme à l'invention, représenté à la figure 1 et désigné dans son ensemble par la référence 2, comprend une embase 4 sur laquelle sont disposés deux pieds 6 destinés à soutenir une unité de marquage de type connu en soi, désigné dans son ensemble par la référence 8. Cette unité de marquage comprend, comme cela est habituel, un mécanisme d'entraínement, par exemple à chariots croisés, ainsi qu'un crayon de marquage non représenté sur cette figure 1, et désigné par la référence 9 aux figures 4 et 5.The marking device according to the invention, shown in Figure 1 and designated as a whole by the reference 2, includes a base 4 on which are arranged two feet 6 intended to support a type marking unit known per se, designated as a whole by the reference 8. This marking unit comprises, as usual, a drive mechanism, for example with crossed carriages, as well a marking pencil not shown in this figure 1, and designated by the reference 9 in Figures 4 and 5.

Le dispositif 2 comprend, d'autre part, un support 10 sensiblement vertical à l'extrémité supérieure duquel est rapporté, par tout moyen connu, un socle 12 présentant, comme cela est visible en particulier à la figure 2, un profil en forme de L.The device 2 comprises, on the other hand, a support 10 substantially vertical at the upper end of which is added, by any known means, a base 12 having, as this is visible in particular in FIG. 2, a profile in L shape.

Afin de garantir une rigidité optimale de l'ensemble de la structure, on peut prévoir de soutenir le socle 12, non seulement au moyen du support 10, mais également d'un autre élément non représenté.In order to guarantee optimal rigidity of the entire structure, we can plan to support the base 12, not only by means of support 10, but also by another element not shown.

Ce socle 12 inclut deux ailes perpendiculaires entre elles et sensiblement coplanaires. Pour des raisons de commodité, dans la suite de la description, on désignera par aile arrière 14 l'aile située en arrière selon le sens d'éjection des plaques marquées, matérialisé par la flèche F à la figure 2. L'autre aile 16 est donc dénommée aile gauche et se trouve fixée sur l'aile 14 par exemple par vissage.This base 12 includes two wings perpendicular to each other and substantially coplanar. For convenience, in the following description, we will designate by rear wing 14 the wing located behind in the direction of ejection of the marked plates, materialized by the arrow F in Figure 2. The other wing 16 is therefore called the left wing and is located fixed on the wing 14 for example by screwing.

Comme le montrent les figures 2 et 3, l'aile gauche 16 est pourvue, sur son flanc intérieur, d'un rebord 18 définissant une surface de portée pour une plaque, comme cela sera explicité par la suite.As shown in Figures 2 and 3, the left wing 16 is provided on its inner flank with a rim 18 defining a bearing surface for a plate, as will be explained thereafter.

Le socle 12 est incliné par rapport à l'horizontale dans deux plans perpendiculaires entre eux. En effet, dans un plan vertical P s'étendant parallèlement à la direction principale de l'aile arrière 14, il est incliné vers le haut par rapport à l'horizontale d'un angle α, dans le sens d'éjection des plaques marquées. De plus, dans le plan vertical P' s'étendant parallèlement à la direction principale de l'aile arrière 14, le socle 12 est incliné vers le bas par rapport à l'horizontale d'un angle α' en direction de l'aile gauche 16. Ces angles α et α' sont par exemple de 45 à 75°.The base 12 is inclined relative to the horizontal in two planes perpendicular to each other. Indeed, in a plane vertical P extending parallel to the main direction of the rear wing 14, it is inclined upwards with respect to horizontally at an angle α, in the direction of ejection of marked plates. Furthermore, in the vertical plane P 'extending parallel to the main direction of the rear wing 14, the base 12 is inclined downward relative to the horizontal by an angle α 'towards the left wing 16. These angles α and α 'are for example from 45 to 75 °.

Une goulotte 20 de section transversale en forme de L, est rapportée au niveau des flancs intérieurs des ailes 14, 16 du socle 12. Cette goulotte 20 s'étend de manière perpendiculaire au socle 12, de sorte qu'elle est également inclinée par rapport à la verticale dans deux plans perpendiculaires entre eux. Cette goulotte 20 constitue un moyen de réception pour des plaques 22 qui y sont disposées de manière à former une pile 23. Ces plaques 22, qui sont rectangulaires, sont susceptible de se déplacer par gravité le long de cette goulotte 20, selon l'axe longitudinal de cette dernière. Un poids 24 dont la fonction sera explicitée par la suite, est en outre rapporté au-dessus de la pile 23 formée par les plaques 22.A trough 20 of L-shaped cross section is reported at the level of the inner flanks of the wings 14, 16 of the base 12. This chute 20 extends perpendicularly to the base 12, so that it is also inclined by relation to the vertical in two perpendicular planes between them. This chute 20 constitutes a means of reception for plates 22 arranged therein so as to form a stack 23. These plates 22, which are rectangular, are susceptible to move by gravity along this chute 20, according to the longitudinal axis of the latter. A weight 24 whose function will be explained later, is further reported above the stack 23 formed by the plates 22.

La goulotte 20 comprend deux parois perpendiculaires, qui seront dénommées respectivement paroi arrière 20A et paroi gauche 20B, selon qu'elles sont disposées au voisinage des ailes respectivement arrière 14 et gauche 16 du socle 12. Chacune de ces parois 20A, 20B est donc inclinée par rapport à la verticale de sorte que les plaques ont tendance à se caler dans l'angle de la goulotte 20.The chute 20 comprises two perpendicular walls, which will be called rear wall 20A and wall respectively left 20B, depending on whether they are arranged in the vicinity of the rear 14 and left 16 wings respectively of the base 12. Each of these walls 20A, 20B is therefore inclined relative to the vertical so that the plates tend to wedge in the corner of chute 20.

Comme le montre de manière plus précise la figure 4, l'aile arrière 14 du socle 12 comprend, au niveau d'une saillie inférieure 25, un poussoir désigné dans son ensemble par la référence 26 qui se compose d'un corps 28 sensiblement parallélépipédique terminé par un doigt 30 aminci. Ce dernier présente une épaisseur inférieure à celle d'une plaque 22. Ce poussoir 26 est mobile selon une direction d'éjection des plaques 22, matérialisée par la flèche F, qui est parallèle à l'axe longitudinal de l'aile 16 du socle 12.As shown in more detail in Figure 4, the rear wing 14 of the base 12 comprises, at a projection lower 25, a pusher designated as a whole by the reference 26 which consists of a substantially parallelepipedic body 28 terminated by a thinned finger 30. The latter presents a thickness less than that of a plate 22. This pusher 26 is movable in a direction of ejection of the plates 22, materialized by arrow F, which is parallel to the axis longitudinal of the wing 16 of the base 12.

La saillie 25 possède, comme le montre la figure 3, un rebord 25A coplanaire avec le rebord 18 de l'aile gauche 16, et s'étendant de part et d'autre du poussoir 26. La paroi arrière 20A de la goulotte 20 repose sur ce rebord 25A, et comprend une encoche 31 destinée au passage du poussoir 26.The projection 25 has, as shown in Figure 3, a rim 25A coplanar with the rim 18 of the left wing 16, and extending on either side of the pusher 26. The rear wall 20A of the chute 20 rests on this flange 25A, and comprises a notch 31 intended for the passage of pusher 26.

La paroi gauche 20B de la goulotte 20 repose, comme le montre en particulier la figure 3, au niveau du décrochement 32 définissant le rebord 18 de l'aile distale 16 du socle 12. Toutefois, on peut prévoir que ce rebord 18 constitue une surface de portée de la goulotte 20.The left wall 20B of the chute 20 rests, as the shows in particular Figure 3, at the step 32 defining the rim 18 of the distal wing 16 of the base 12. However, it can be expected that this rim 18 constitutes a trough bearing surface 20.

Un bras 34, parallèle à l'aile gauche 16 du socle 12, est rapporté au niveau de l'extrémité libre de l'aile arrière 14 de ce socle 12. Il est relié à deux traverses 36A, 36B superposées respectivement supérieure et inférieure, qui sont parallèles à l'aile arrière 14 du socle 12. Ces traverses, illustrées en particulier aux figures 3 et 4, sont assujetties à l'extrémité libre de l'aile gauche 16 de ce socle 12.An arm 34, parallel to the left wing 16 of the base 12, is reported at the free end of the rear wing 14 of this base 12. It is connected to two superimposed sleepers 36A, 36B respectively upper and lower, which are parallel to the rear wing 14 of the base 12. These crosspieces, illustrated in particular to Figures 3 and 4, are subject to the end free of the left wing 16 of this base 12.

Les distances séparant respectivement l'aile arrière 14 des traverses 36, ainsi que l'aile gauche 16 du bras 34, sont réglables grâce à la présence de lumières 38 dans lesquelles pénètrent des tiges non représentées susceptibles d'être déplacées au moyen de boutons moletés 42. Le bras 34 est pourvu d'un rebord 44 illustré notamment aux figures 2 et 5 et disposé en regard du rebord 18 dont est muni l'aile gauche 16, ces deux rebords étant disposés dans un même plan parallèle au plan du socle.The distances between the rear wing 14 respectively sleepers 36, as well as the left wing 16 of the arm 34, are adjustable thanks to the presence of lights 38 in which penetrate unrepresented stems likely to be moved by means of knurled buttons 42. The arm 34 is provided a rim 44 illustrated in particular in FIGS. 2 and 5 and arranged opposite the rim 18 with which the left wing 16 is provided, these two ledges being arranged in the same plane parallel to the plane of the basement.

L'écartement séparant les deux traverses 36A, 36B est réglable par l'intermédiaire de moyens connus en soi, non représentés. La traverse inférieure 36B fait saillie, par rapport à la traverse supérieure 36A, en direction de l'aile arrière 14 du socle 12, de manière à constituer un rebord 46 disposé dans le même plan que les rebord 18 et 44 décrits précédemment. Un réceptacle 48 est en outre assujetti à la traverse inférieure 36B, au niveau de son côté opposé au socle 12.The spacing separating the two crosspieces 36A, 36B is adjustable by means known per se, not represented. The bottom crosspiece 36B projects, by relative to upper cross member 36A, in the direction of the wing rear 14 of the base 12, so as to constitute a flange 46 arranged in the same plane as the flanges 18 and 44 described previously. A receptacle 48 is further subject to the bottom cross member 36B, at its side opposite the base 12.

Comme le montrent les figures 2 et 5, la plaque inférieure 22A de la pile 23 repose, par ses quatre bords, sur les rebords coplanaires correspondants 18, 25A, 44 et 46 dont sont pourvus respectivement l'aile gauche 16, la saillie 25, le bras 34 et la traverse inférieure 36B. De plus, cette plaque 22A est maintenue transversalement par l'intermédiaire de l'extrémité inférieure de la paroi arrière 20A de la goulotte 20. Enfin, lors de l'action du crayon de marquage 9 sur la face inférieure de la plaque inférieure 22A, illustrée à la figure 3A, les plaques supérieures, ainsi que le poids 24, assurent le maintien de la plaque inférieure 22A à l'encontre de l'action de la tête de marquage.As shown in Figures 2 and 5, the bottom plate 22A of the stack 23 rests, by its four edges, on the edges corresponding coplanars 18, 25A, 44 and 46 which are provided respectively the left wing 16, the projection 25, the arm 34 and the bottom crosspiece 36B. In addition, this plate 22A is held transversely through the end bottom of the rear wall 20A of the chute 20. Finally, during the action of the marking pencil 9 on the underside of the lower plate 22A, illustrated in FIG. 3A, the upper plates, as well as the weight 24, ensure the holding the bottom plate 22A against the action of the marking head.

La plaque 22B disposée immédiatement au-dessus de la plaque 22A est maintenue transversalement par l'extrémité inférieure de la goulotte et par la traverse 36A.Plate 22B disposed immediately above the plate 22A is held transversely by the end lower of the chute and through the cross 36A.

Les figures 3 et 4 illustrent la phase d'éjection de la plaque inférieure 22A. Cette éjection est réalisée par l'intermédiaire du poussoir 26. Le doigt 30 aminci de ce dernier pénètre dans l'encoche 31 de la paroi arrière 20A, entre en contact avec le chant de la plaque 22A et la conduit entre les faces en regard des traverses 36A, 36B qui délimitent ainsi un chemin de guidage 50 intercalaire. La distance séparant ces deux traverses 36A, 36B est de préférence comprise entre une et une fois et demie l'épaisseur de chaque plaque 22. La course du poussoir 26 est supérieure aux dimensions des plaques 22, selon la direction d'éjection de ces dernières. De plus, ce doigt 30 présente, selon la direction d'éjection des plaques 22, des dimensions supérieures à celles des traverses 36A, 36B. De la sorte, en fin de course du poussoir, le doigt 30 de ce dernier pénètre dans le chemin de guidage 50 et éjecte la plaque inférieure 22A qui se trouve recueillie au sein du réceptacle 48.Figures 3 and 4 illustrate the ejection phase of the bottom plate 22A. This ejection is carried out via of the push-piece 26. The thinned finger 30 of the latter enters the notch 31 of the rear wall 20A, enters contact with the edge of the plate 22A and the conduit between the opposite faces of the sleepers 36A, 36B which thus delimit a guide path 50 intermediate. The distance between these two sleepers 36A, 36B is preferably between one and 1.5 times the thickness of each plate 22. The stroke of the pusher 26 is greater than the dimensions of the plates 22, according to the direction of ejection of the latter. In addition, this finger 30 has, in the direction of ejection of the plates 22, dimensions larger than those of the cross-pieces 36A, 36B. Of the so, at the end of the pusher stroke, the finger 30 of the latter enters guide path 50 and ejects the plate lower 22A which is collected within the receptacle 48.

On agit alors, par l'actionneur non représenté, sur le poussoir 26 de manière à le faire revenir à sa position rétractée, représentée à la figure 4. La plaque 22B, disposée immédiatement au-dessus de la plaque inférieure 22A, prend alors la place de cette dernière et se trouve à son tour maintenue par les rebords 18, 25A, 44 et 46. Une nouvelle opération de marquage, au moyen du crayon 9, peut alors être mise en oeuvre sur cette plaque 22B qui sera ensuite éjectée après marquage, de manière analogue à l'opération décrite ci-dessus.We then act, by the actuator not shown, on the pusher 26 so as to return it to its position retracted, shown in Figure 4. The plate 22B, arranged immediately above the bottom plate 22A, takes then the place of the latter and is in turn maintained by edges 18, 25A, 44 and 46. A new marking operation, using the pencil 9, can then be implementation on this plate 22B which will then be ejected after marking, in a manner analogous to the operation described above.

Au fur et à mesure des opérations de marquage, chacune des plaques 22 formant la pile 23 se déplace le long de la goulotte 20 par gravité, est marquée par le crayon 9 puis se trouve expulsée par le poussoir 26. Lorsque le nombre de plaques 22 formant la pile 23 est réduit, le poids 24 est particulièrement avantageux en ce sens qu'il permet le maintien de la plaque inférieure pendant son marquage, à l'encontre de l'action du crayon 9.As the marking operations progress, each of the plates 22 forming the stack 23 moves along the chute 20 by gravity, is marked by pencil 9 and then is expelled by the pusher 26. When the number of plates 22 forming the pile 23 is reduced, the weight 24 is particularly advantageous in that it allows the maintenance of the plate lower during its marking, against the action of the pencil 9.

Le dispositif conforme à l'invention a été représenté, dans l'ensemble des figures, avec une goulotte d'alimentation inclinée par rapport à la verticale. Bien entendu, on peut prévoir que cette goulotte présente un axe longitudinal sensiblement vertical. Dans ce cas, ses parois entourent l'ensemble du périmètre des plaques qui y sont admises.The device according to the invention has been shown, in all of the figures, with a feed chute inclined to the vertical. Of course, we can provide that this chute has a longitudinal axis substantially vertical. In this case, its walls surround the entire perimeter of the plates admitted to it.

De plus, on peut prévoir des supports plans de marquage dont la forme ne soit pas rectangulaire, en particulier ronde ou ovale.In addition, planar marking supports can be provided. the shape of which is not rectangular, in particular round or oval.

L'invention permet de réaliser les objectifs précédemment mentionnés. En effet, le fait de marquer la face inférieure de la plaque inférieure 22A de la pile 23 permet de s'affranchir de la présence d'un ensemble de convoyage de cette plaque inférieure en direction du crayon de marquage, comme cela était le cas dans l'art antérieur. Le maintien de cette plaque inférieure à marquer est assuré par l'intermédiaire d'éléments mécaniques de conformation très simple, ainsi que par les plaques supérieures de sorte qu'il est uniquement nécessaire de rapporter, le cas échéant, un poids au-dessus de la pile de plaques.The invention makes it possible to achieve the objectives previously mentioned. Indeed, the fact of marking the underside of the bottom plate 22A of the stack 23 makes it possible to overcome the presence of a conveyor assembly for this lower plate towards the marking pen, as was the case in the prior art. Maintaining this bottom plate to be marked is ensured by means of elements mechanics of very simple conformation, as well as by top plates so it is only necessary to if necessary, bring a weight above the stack of plates.

Le fait de prévoir une goulotte de réception inclinée par rapport à la verticale présente également des avantages spécifiques. En effet, cette goulotte possède une structure particulièrement simple, puisqu'elle est constituée uniquement de deux branches formant un L. Le chargement des plaques est donc notablement simplifié par rapport à une goulotte entourant l'ensemble du périmètre des plaques.The fact of providing a reception chute inclined by vertical also has advantages specific. Indeed, this chute has a structure particularly simple, since it consists only of two branches forming an L. The loading of the plates is therefore significantly simplified compared to a surrounding chute the entire perimeter of the plates.

En outre, la visibilité de la zone de marquage par l'opérateur est optimale durant la phase de marquage proprement dite, ce qui est particulièrement avantageux. Enfin, une goulotte inclinée est susceptible de s'adapter à toutes sortes de plaques, puisqu'elle s'étend seulement sur une partie de leur périphérie. La présence de moyens permettant de régler la distance séparant respectivement l'aile proximale du socle par rapport aux traverses ainsi que l'aile distale du socle par rapport au bras, permet d'assurer le maintien de plaques de tailles différentes.In addition, the visibility of the marking area by the operator is optimal during the marking phase properly said, which is particularly advantageous. Finally, a inclined chute is capable of adapting to all kinds of plates, since it extends only over part of their periphery. The presence of means to adjust the distance between the proximal wing and the base respectively relation to the crosspieces as well as the distal wing of the base by arm, ensures the maintenance of plates of different sizes.
