Abstract

The mechanism is intended for sorting objects, e.g. fruit, into different sizes. It comprises rollers (8) with stub shafts (9) at both ends which are carried between links (2) of two parallel endless chains and roll on a straight track (10). Each chain link (2) has a disc-shaped portion (3) with cut-off segment (5) and a longitudinally forked portion (4) receiving the portion (3) of the preceding link. Each forked portion has a curved slot (7) concentric with the disc and the portion (3) has a bore (6) near one corner. Each stub shaft (9) extends through a slot (7) of one and a bore (6) of the adjoining link. The links are guided at top (12,14 etc.) and bottom (11,13 etc.) to vary the relative level between the links to cause their relative rotation and thus successively alter the distance between adjacent rollers.

Une chine a pas variable est décrite dans la demande de brevet DE - Ob 24'31'668, chaîne qui permet, dans certaines zones, des vitesses de transport différentes. A china with variable pitch is described in the patent application DE - Ob 24'31'668, chain which allows, in certain zones, different transport speeds.

Le brevet FR - 2'341'074 se rapporte b une chaîne qui permet de modifier la distance d'éléments de transport grâce à une oscillation automatique d'organes. The patent FR - 2'341'074 relates to a chain which makes it possible to modify the distance of transport elements thanks to an automatic oscillation of organs.

Dons le brevet CE - 604'935 est décrite une machine b trier des pommes-de- terre. Cette machine comprend deux tambours longitudinaux déplacables l'un par rapport à l'autre, un des tambour portant, sur sa chemise, un organe de guidage en forme de vis hélicoïdale. Given the CE patent - 604,935, a machine for sorting potatoes is described. This machine comprises two longitudinal drums movable relative to one another, one of the drums carrying, on its jacket, a guide member in the form of a helical screw.

Le brevet DE - 23'64'829 concerne un dispositif pour trier des fruits et de. légumes d'après leur grandeur au moyen de deux tronçons de channe parallè- les sans fin et qui portent des éléments oscillants espacés les uns des autres de distances égales et munis, chacun, de deux rouleaux, les tourillons des extrémités d'un des rouleaux étant guidé dans les maillons ae la chaîne et portant des éléments cscillants, de sorte qu'en déplaçant les éléments @scillants au moyen de rails de guidage, l'espace entre les rouleaux d'une paire de rouleaux qui se suivent varie. La fente entre les deux rouleaux d'une paire est recouverte d'une tôle. La distance réglable entre les paires de rouleaux sert à trier les produits d'après leur grandeur. Patent DE - 23'64'829 relates to a device for sorting fruit and. vegetables according to their size by means of two endless parallel sections of chain which carry oscillating elements spaced from each other by equal distances and each provided with two rollers, the pins of the ends of one of the rollers being guided in the links ae the chain and carrying cscillant elements, so that by moving the @scillant elements by means of guide rails, the space between the rollers of a pair of successive rollers varies. The slot between the two rollers of a pair is covered with a sheet. The adjustable distance between the pairs of rollers is used to sort the products according to their size.

L'invention a pour but de fournir une chaîne de triage, notamment pour trier des légumes et des produits industriels d'après leur grandeur, chaîne dans laquelle l'interstice de triage est déterminé par les rouleaux gui se suivent et dans laquelle les maillons sont façonnés de maniere que l'espace entre les rouleaux puisse être réglé sens fin en les déplaçant vers le haut. The object of the invention is to provide a sorting chain, in particular for sorting vegetables and industrial products according to their size, chain in which the sorting gap is determined by the rollers which follow one another and in which the links are shaped so that the space between the rollers can be adjusted finely by moving them upwards.

Conformément x l'invention ce but est atteint par le fait que les organes de réglage sont constitués par des maillons longitudinaux communs aux deux brins de la channe, de forme circulaire et présentant une portion en forme de disque avec une partie rectiligne, ainsi qu'une portion en forme de fourche destinée à recevoir la portion en forme de disque de l'organe de réglage qui le suit, par le fait que la portion en forme de disque, a proximité d'un des coins de la partie rectiligne, présente un trou et que la portion en forme de fourche est munie d'une fonte concentrique, et par le fait que les rouleaux de triage portent, à leurs extrémités, des tourillons, chaque tourillon traversant la fente concentrique de l'organe de réglage qui le précède et pénétrant dans le trou de l'organe de réglage qui le suit.  In accordance with the invention, this object is achieved by the fact that the adjustment members are constituted by longitudinal links common to the two strands of the chain, of circular shape and having a disc-shaped portion with a rectilinear part, as well as a fork-shaped portion intended to receive the disc-shaped portion of the adjusting member which follows it, by the fact that the disc-shaped portion, near one of the corners of the rectilinear part, has a hole and that the fork-shaped portion is provided with a concentric cast iron, and by the fact that the sorting rollers carry, at their ends, trunnions, each trunnion passing through the concentric slot of the adjustment member which precedes it and penetrating into the hole of the adjusting member which follows it.

Le dessin annexé illustre. à titre d'exemple, une forme de réalisation conforme a l'invention. The accompanying drawing illustrates. by way of example, an embodiment in accordance with the invention.

La fig. 1 est une vue la de côté de la chaîne, les espaces entre les rouleaux étant différents, et
la fig. 2 est une vua en plan de la fig. 1, partiellement en coupe.Fig. 1 is a side view of the chain, the spaces between the rollers being different, and
fig. 2 is a plan view of FIG. 1, partially in section.

La chatne sans fin représentés comprend deux brins 1 qui sont constitués par des organes de réglage 2 qui forment les maillons de la chaîne. Les organes de rEglage 2 sont circulaires et présentent une portion en forme de disque 3 et une portion en forme de fourche 4, cette dernire recevant la portion en forme de disque 3 de l'organe de réglage qui le suit. La portion en forme de disque 3 présente une partie droite et un trou 6 est pratiqué a proximité d'un des coins de cette partie droite, dans la portion en forme de disque 3. Une fente concentrique 7 est prévue dans la portion en forme de fourche 4. The endless chain shown comprises two strands 1 which are constituted by adjusting members 2 which form the links of the chain. The adjustment members 2 are circular and have a disc-shaped portion 3 and a fork-shaped portion 4, the latter receiving the disc-shaped portion 3 of the adjusting member which follows it. The disc-shaped portion 3 has a straight portion and a hole 6 is made near one of the corners of this straight portion, in the disc-shaped portion 3. A concentric slot 7 is provided in the shaped portion. fork 4.

Des rouleaux de triage 8, montés à angle droit par rapport au sons de d6- placement de la chatne 1, sont reliEs sux deux brins de la chaîne sans fin par des tourillons 9. Chaque tourillon 9 est engagE dsns la fente concentrique 7 de l'organe de réglage 2 qui le précède, dans le trou 6 de l'organe de réglage 2 qui le suit et dans la portion en forme de disque 3 et de l'organe de réglage 2 qui le précède et qui tend dans ce dernier par la portion en forme de four- che 4. Sorting rollers 8, mounted at right angles to the movement sounds of the cat 1, are connected to two strands of the endless chain by pins 9. Each pin 9 is engaged in the concentric slot 7 of the adjuster 2 which precedes it, in the hole 6 of the adjuster 2 which follows it and in the disc-shaped portion 3 and of the adjuster 2 which precedes it and which tends in the latter by the fork-shaped portion 4.

Les rouleaux de triage 8 sont guidés, dans la zone de triage de la machine a calibrer, sur une voie rectiligne 10. En déplaçant les organes de réglage 2 vers le haut, ces derniers oscillent les uns par rapport aux antres et les tourillons 9 se déplacant dans la fente 7 de l'organe de réglage correspondant, de sorte que la distance entre les tourillons 9 de deux rouleaux qui se suivent varie. The sorting rollers 8 are guided, in the sorting area of the calibrating machine, on a rectilinear track 10. By moving the adjusting members 2 upwards, the latter oscillate relative to each other and the pins 9 are moving in the slot 7 of the corresponding adjusting member, so that the distance between the pins 9 of two successive rollers varies.

La fig. 1 montre, dans sa partie droite, un organe de rEglage 2 dans la position la plus basse de la zone de triage, position pour laquelle la distance entre les axes des rouleaux de triage 8 est la plus faible. Dan cette zone, ce sont les objets les plus petits qui s'échappent entre les rouleaux de triage 8. Fig. 1 shows, in its right part, an adjustment member 2 in the lowest position of the sorting zone, position for which the distance between the axes of the sorting rollers 8 is the smallest. In this area, the smallest objects escape between the sorting rollers 8.

Dans cette zone également, l'organe de réglage w est guidé par un rail inféri- eur 11 et par un rail supérieur 12.Also in this zone, the adjusting member w is guided by a lower rail 11 and by an upper rail 12.

L'organe de réglage 2 situE au centre de la fig. 1 a été déplacé vers le haut sur la portion inclinée d'un rail de guidage 13 pour que le tourillon 9 du rouleau de triage 8 se trouve pratiquement à mi-distance dans la fente 7. L'intervalle entre les rouleaux de triage 8 qui se suivent a donc augmenté. La portion rectiligne du rail de guidage 13 détermine l'intervalle dans la zone de de triage et correspond a la grandeur des objets à évacuer. Un rail supérieur 14 empêche une rotation ultérieure de l'organe de réglage 2. The adjusting member 2 located in the center of FIG. 1 has been moved upwards on the inclined portion of a guide rail 13 so that the journal 9 of the sorting roller 8 is practically halfway in the slot 7. The interval between the sorting rollers 8 which follow each other has increased. The straight portion of the guide rail 13 determines the interval in the sorting area and corresponds to the size of the objects to be removed. An upper rail 14 prevents further rotation of the adjusting member 2.

Dans la partie gauche de la fig. 1, l'organe de réglage 2 a atteint sa po eition la plus haute dans la zone de triage. La distance entre les axes des deux rouleaux de triage 8 qui se suivent est la plus grande et, dans cette zonet se sont les objets les plus grands qui sont évacués. In the left part of fig. 1, the adjusting member 2 has reached its highest position in the sorting area. The distance between the axes of the two sorting rollers 8 which follow one another is the greatest and, in this zone, the largest objects are removed.

La chaîne se déplace, dans la zone de triage, de manière que les organes de réglage 2 soient successivement plus hauts, pour que, d'abord, les objets les plus petits soient évacués, puis, successivement, les autres, jusqu'aux plue grands.  The chain moves in the sorting area so that the adjusting members 2 are successively higher, so that, first, the smallest objects are evacuated, then, successively, the others, up to the highest great.
