La presente invention concerne un dispositif de tri de The present invention relates to a sorting device for
produits allonges.elongated products.
Au sens de ['invention, de tels produits allonges possedent une dimension principale, ou longueur, qui est superieure a leur dimension transversale, ou largeur. De nombreux secteurs indus-triels font appel a ces produits allonges. On citera ainsi, notamment, les domaines Within the meaning of the invention, such elongated products have a main dimension, or length, which is greater than their transverse dimension, or width. Many industrial sectors use these extended products. These include, in particular, the fields
alimentaire, medical et chimique.food, medical and chemical.
Dans le premier de ceux-ci, on retrouve par exemple les dragees de chewing-gum, ou encore les confiseries. Dans le second de ces secteurs, on fait notamment appel a des In the first of these, we find, for example, chewing gum dragees, or even confectionery. In the second of these sectors, use is made in particular of
comprimes secables, ou encore a des gelules. breakable tablets, or capsules.
De tels produits allonges vent egalement utilises dans d'autres domaines industrials. Ainsi, on citera en outre, a titre non limitatif, les elements de visserie, les pieces plastiques, les allumettes, ou encore les pierres a briquet. Il se revere souvent necessaire de proceder a un tri dimensionnel de ces produits, en ce qui concerne leur longueur, avant de les soumettre a un traitement ulterieur, Such elongated products are also used in other industrial fields. Thus, mention will also be made, without limitation, of fasteners, plastic parts, matches, or even lighter stones. It often turns out to be necessary to carry out a dimensional sorting of these products, as regards their length, before subjecting them to a subsequent treatment,
en particulier leur conditionnement. in particular their packaging.
Ainsi, dans le domaine du chewing-gum, si la longueur d'une dragee consideree est trop faible, ceci signifie que cette dragee est cassee. Il y a done lieu de la mettre au Thus, in the field of chewing gum, if the length of a dragee considered is too short, this means that this dragee is broken. It should therefore be
rebut.scum.
La situation est inverse dans le domaine des pierres a briquet. En effet, si la longueur d'une pierre est superieure a une valeur predeterminee, elle ne peut etre The situation is the opposite in the field of lighter stones. Indeed, if the length of a stone is greater than a predetermined value, it cannot be
utilisee en ltetat.used in condition.

deux produits allonges de longueurs differentes. two elongated products of different lengths.
La figure 1 illustre un produit allonge, au sens de la presente invention. I1 s'agit d'une dragee de chewing-gum 2, dont la dimension principale, ou longueur L, est FIG. 1 illustrates an elongated product, within the meaning of the present invention. It is a chewing gum dragee 2, the main dimension of which, or length L, is
superieure a la dimension transversale, ou largeur 1. greater than the transverse dimension, or width 1.
Le dispositif de tri conforme a l' invention est represente sur la figure 2. I1 comprend des moyens de convoyage, qui vent constitues par un couloir vibrant, The sorting device according to the invention is shown in FIG. 2. It comprises conveying means, which are constituted by a vibrating corridor,
designe dans son ensemble par la reference 4. denoted as a whole by reference 4.
Ce couloir repose, de facon connue en soi, sur un chassis 6, qui comprend des pieds 8, ainsi que des longerons 10. Le couloir repose sur le chassis, avec interposition de suspensions 14. I1 est par ailleurs prevu des vibrateurs 16, assurant la mise en mouvement du couloir This corridor rests, in a manner known per se, on a chassis 6, which includes feet 8, as well as longitudinal members 10. The corridor rests on the chassis, with the interposition of suspensions 14. I1 is also provided with vibrators 16, ensuring setting the corridor in motion
4, de maniere habituelle.4, in the usual way.
Ce couloir 4 comprend une tremie arriere 18, a partir de laquelle stetend une plage arriere 20, en faisant reference a l'avancee des produits. Cette plage 20 est prolongee par une tole 22, ou grille, percee d' orifices 24, This corridor 4 includes a rear hopper 18, from which a rear shelf 20 extends, making reference to the advance of the products. This area 20 is extended by a sheet 22, or grid, pierced with orifices 24,
de forme adaptee aux produits.form adapted to the products.
Cette t81e perforce primaire 22 permet d'assurer, de facon connue en soi, un tri entre les dragees individuelles, de largeur correcte, et les groupes de dragees accolees au niveau de leur bord lateral, qui doivent etre mises au rebut. Ces derrieres restent a la surface de la t81e 22, puis vent evacuees lateralement par This primary perforce t81e 22 ensures, in a manner known per se, a sorting between the individual casings, of correct width, and the groups of casings joined at their lateral edge, which must be discarded. These behinds remain on the surface of the t81e 22, then wind evacuated laterally by
une goulotte 26.a chute 26.
28411 6128411 61
En revanche, les dragees individuelles de largeur correcte passent au travers des orifices 24, et vent recues sur une plage principale 28 du couloir vibrant 4. Wiles vent alors dlrigees vers une grille ou to81e principale 30, qui est percee d'orifices 32, dont les dimensions vent sensiblement inferieures a celles des orifices 24 et dont la forme, en l' occurrence circulaire, est adaptee aux produits. Cette t81e perforce 30 est surmontee d'une plaque 34, comme le montre notamment la figure 3. Son extremite avant communique avec un entonnoir de collecte 36, alors qu'une goulotte supplementaire 38 est disposee au-dessous de cette On the other hand, the individual dragees of correct width pass through the orifices 24, and wind received on a main range 28 of the vibrating corridor 4. Wiles then wind towards a main grid or to81e 30, which is pierced with orifices 32, of which the wind dimensions substantially lower than those of the orifices 24 and the shape of which, in this case circular, is adapted to the products. This t81e perforce 30 is surmounted by a plate 34, as shown in particular in Figure 3. Its front end communicates with a collection funnel 36, while an additional chute 38 is disposed below this
t81e 30.t81e 30.
Le tri opere par le dispositif de ['invention, au niveau de la t81e perforce 30, peut 8etre explicite comme suit. On fixe tout d'abord une longueur donnee, qui est par exemple egale au deux tiers de la longueur nominale d'une dragee 2. Ainsi, si la longueur d'une dragee consideree est inferieure a cette valeur predeterminee, la dragee en The sorting carried out by the device of the invention, at the level of the perforce 30, can be explained as follows. We first set a given length, which is for example equal to two thirds of the nominal length of a dragee 2. Thus, if the length of a considered dragee is less than this predetermined value, the dragee in
question sera mise au rebut.question will be discarded.
I1 faut done que seules les dragees, dont la longueur est inferieure a cette valeur seuil, passent au travers des orifices 32. Par consequent, les dragees de longueur superieure ne doivent pas basculer au-dessous de la t81e, It is therefore necessary that only the dragees, the length of which is less than this threshold value, pass through the orifices 32. Consequently, the dragees of greater length must not tip below the head,
mais doivent 8tre dirigees vers l'entonnoir de collecte 36. but should be directed to collection funnel 36.
L' essence de ['invention consiste done a moduler, d'une part, la section transversale des orifices 32 et, d'autre part, la distance h separant la plaque 34 et la The essence of the invention therefore consists in modulating, on the one hand, the cross section of the orifices 32 and, on the other hand, the distance h separating the plate 34 and the
grille 30, de maniere a operer le tri evoque ci-dessus. grid 30, so as to operate the sorting mentioned above.
A titre d'exemple non limitatif, si l'on desire que senles les dragees dont la longueur est inferieure a 16 mm passent au travers de la t81e perforce 30, le diametre des By way of nonlimiting example, if it is desired that the dragees whose length is less than 16 mm pass through the perforce tube 30, the diameter of the
28411 6128411 61
orifices 32 est alors fixe a 13 mm, alors que la hauteur h orifices 32 is then fixed at 13 mm, while the height h
de la plaque est fixee a environ 10 mm. of the plate is fixed at approximately 10 mm.
I1 est a noter que les trots dimensions des produits a trier, a savoir leur longueur, leur largeur et leur epaisseur, vent liees et interactives. En effet, la modification de l'une de ces dimensions entrane des modifications et/ou des reglages au niveau du dispositif de It should be noted that the dimensional trots of the products to be sorted, namely their length, their width and their thickness, are linked and interactive. Indeed, the modification of one of these dimensions leads to modifications and / or adjustments at the level of the
tri, en particulier de la tole perforce. sorting, in particular of perforce sheet.
La figure 3- illustre plus precisement le trajet de lo deux dragees, dont l'une 21 possede une longueur L inferieure a la longueur predeterminee, alors que l'autre 22 Figure 3- illustrates more precisely the path of lo two dragees, one of which 21 has a length L less than the predetermined length, while the other 22
possede une longueur L2 superieure a cette m8me valeur. has a length L2 greater than this same value.
Cette difference s'explique par le fait que la dragee 21 a This difference is explained by the fact that dragee 21 has
par exemple ete cassee, lors de son traitement prealable. for example was broken, during its preliminary treatment.
Lors de son deplacement, cette dragee 21 commence a basculer vers le teas de la tole 30, au travers d'un orifice 32. Lors de ce mouvement, elle n'entre pas en contact avec la plaque 34, etant donne que cette dragee possede une During its movement, this casing 21 begins to tilt towards the teas of the sheet 30, through an orifice 32. During this movement, it does not come into contact with the plate 34, since this casing has a
faible longueur.short length.
Par consequent, elle penetre entierement au travers de cet orifice 32, et se trouve dirigee par gravite vers la goulotte 38, selon la fleche F. Cette dragee 21 est alors Consequently, it penetrates entirely through this orifice 32, and is directed by gravity towards the trough 38, according to the arrow F. This dragee 21 is then
mise au rebut.scrapped.
En revanche, touj ours en reference a la figure 3, lorsque la dragee longue 22 initie son mouvement de basculement vers le teas, au travers d'un orifice 32, son extremite superieure 2' 2 vient en butee contre la face inferieure de la plaque 34. Cette derriere empeche done la dragee 22 de basculer, et ainsi de quitter la surface de la On the other hand, always with reference to FIG. 3, when the long casing 22 initiates its tilting movement towards the teas, through an orifice 32, its upper end 2 ′ 2 abuts against the lower face of the plate 34. This behind therefore prevents dragee 22 from tipping over, and thus leaving the surface of the
t81e perforce 30.t81e perforce 30.
De la sorte, la dragee 22 ne chute pas de la t81e 30, lors de son deplacement vers l' avant. Wile se retrouve In this way, the dragee 22 does not fall from the t81e 30, when it is moved forward. Wile finds himself
alors collectee au niveau de l'entonnoir final 36. then collected at the final funnel 36.
28411 6128411 61
Il est a noter que les soles perforees 22 et 30 vent avantageusement amovibles et interchangeables. Ceci confere une hygiene satisfaisante au dispositif de ['invention, et It should be noted that the perforated sole 22 and 30 are advantageously removable and interchangeable. This gives satisfactory hygiene to the device of the invention, and
permet en outre de changer les parametres de tri. also allows you to change the sorting parameters.
Par ailleurs, la hauteur _ de la plaque 34 peut etre reglee, par tout moyen approprie, non represente. Ceci permet done de moduler la valeur de la longueur seuil, au Furthermore, the height _ of the plate 34 can be adjusted, by any suitable means, not shown. This therefore makes it possible to modulate the value of the threshold length, at
dessous de laquelle les dragees vent mises au rebut. below which the dragees are discarded.
Il y a egalement lieu de remarquer que, en l' absence de la plaque 34, la tole 30 ne permettrait pas d'operer une quelconque discrimination, en ce qui concerne la longueur des dragees. En effet, dans ce cas, les dragees plus longues ne viendraient pas en butee contre la plaque, de sorte qu'elles passeraient egalement au travers des It should also be noted that, in the absence of the plate 34, the sheet 30 would not allow any discrimination to be made with regard to the length of the dragees. In fact, in this case, the longer casings would not come into abutment against the plate, so that they would also pass through the
orifices 32.holes 32.
L' invention n'est pas limitee a l'exemple decrit et represente. Ainsi, dans cet exemple, on met au rebut les produits dont la longueur est inferieure a une valeur souhaitee. Il est egalement possible, grace au dispositif de l' invention, de mettre au rebut des produits dont la longueur est trop importante, en particulier dans le domaine des pierres a briquet. The invention is not limited to the example described and shown. Thus, in this example, products whose length is less than a desired value are discarded. It is also possible, thanks to the device of the invention, to discard products whose length is too great, in particular in the field of lighter stones.
