Abstract

The invention relates to a device which enables the logs to be sorted continuously according to certain criteria in an error-free and steady manner. It is made up of a conveyor belt (1) which circulating in metal troughs (2), the latter being mounted on pivots (3). These troughs can tilt from the right to the left by means of jacks (4), the whole assembly being mounted on a beam (5). The assembly is moved by a variation in the speed as a function of the weight of the logs. The device according to the invention is particularly designed for sorting logs of wood continuously.

Description

DISPOSITIF POUR TRIER DES BILLONS A GRANDE VITESSE SELON DES
CRITERES DIMMENSIONELS
La présente invention concerne un dispositif pour le triage des billons de bois en dimension ou qualité d'après des informations d'un mesureur à codeur linéaire ou d'un système de reconnaisance quelconque.DEVICE FOR SORTING BALLS AT HIGH SPEED ACCORDING TO
DIMENSIONAL CRITERIA
The present invention relates to a device for sorting logs in size or quality based on information from a linear encoder or any recognition system.

I1 existe déjà plusieurs systèmes de trieur fabriqués dans le monde entier. Les brevets déposés à ce sujet sont brevet DE 3.446.538 brevet DE 3.511.936 brevet US 4.024.948 brevet SU 1.426.901 brevet SU 1.498.676. Leur particularité en général est leur fabrication en grosse mécanique, chaînes, basculeur, éjecteur, butée, d'une maintenance lourde. Ils sont peu précis dans la chute des billons. There are already several sorter systems manufactured worldwide. The patents filed on this subject are patent DE 3,446,538 patent DE 3,511,936 US patent 4,024,948 patent SU 1,426,901 patent SU 1,498,676. Their particularity in general is their manufacture in large mechanics, chains, rocker, ejector, stop, of heavy maintenance. They are not very precise in the fall of the ridges.

Le dispositif selon l'invention permet de faire circuler les billons sur une bande transporteuse à grande vitesse afin de les classer à des endroits déterminés tout le long du trieur d'une façon précise et de les ranger paralèlles entre eux. La reprise des billons est de ce fait aisée et rapide. The device according to the invention makes it possible to circulate the logs on a conveyor belt at high speed in order to classify them at determined locations all along the sorter in a precise manner and to store them parallel to one another. The recovery of the logs is therefore easy and quick.

Les dessins anexés illustrent l'invention
La figure 1 représente en coupe, la partie pneumatique du dispositif selon l'invention.The annexed drawings illustrate the invention
Figure 1 shows in section, the pneumatic part of the device according to the invention.

La figure 2 représente en coupe, le pivot de l'auge du dispositif selon l'invention. Figure 2 shows in section, the pivot of the trough of the device according to the invention.

En référence à ces dessins, le dispositif comporte une bande transporteuse (1) glissant dans une auge métallique (2) et revenant sur son retour dans la poutre (5).  With reference to these drawings, the device comprises a conveyor belt (1) sliding in a metal trough (2) and returning to its return in the beam (5).

Tout le long du trieur des segments d'auge (2) sont montés, oscillant par l'intermédiaire de pivots (3). Chaque auge (2) en pivotant, soit à droite, soit à gauche correspond à une case de rangement. Throughout the sorter, trough segments (2) are mounted, oscillating by means of pivots (3). Each trough (2) by pivoting, either to the right or to the left, corresponds to a storage box.

Le mouvement de ces dernières se fait par l'intermédiaire de vérins (4) montés deux par deux tête bêche. Suivant l'alimentation en air, les tiges sortiront une ou deux ou se retracteront. The movement of the latter is done by means of jacks (4) mounted two by two head to tail. Depending on the air supply, the rods will come out one or two or retract.

Suite à un calcul ou à une information venant de l'ex- térieur le billon (8) sera acheminé par la bande transporteuse (1) tout le long du trieur afin d'être classé grâce à un segment d'auge (2). Following a calculation or information from outside the log (8) will be conveyed by the conveyor belt (1) all along the sorter in order to be classified using a trough segment (2).

Dans ce cas l'auge pivote à droite (9) le billon (8) perdra son équilibre et roulera dans sa case. Comme chaque billon a des dimensions différentes et de ce fait, des poids différents, l'inertie de ces derniers est différente. Pour palier à ce problème un convertisseur de fréquence alimentant le moteur de la bande transporteuse (1) variera proportionnellement au poids du billon (8) dans une décélération jusqu'à l'arrêt complet devant la case pour que celui-ci roule d'une façon parfaite et parallèle devant les autres billons rangés. In this case the trough swivels to the right (9) the log (8) will lose its balance and roll in its box. As each log has different dimensions and therefore different weights, the inertia of the latter is different. To overcome this problem, a frequency converter supplying the motor of the conveyor belt (1) will vary in proportion to the weight of the log (8) in a deceleration until the complete stop in front of the box so that it rolls with a perfectly and parallel in front of the other rows.

Par l'intermédiaire du convertisseur de fréquence la bande transporteuse (1) va doubler sa vitesse pour rattraper le temps perdu à l'éjection lors du redémarrage suite à l'éjection d'un billon (8).  By means of the frequency converter, the conveyor belt (1) will double its speed to make up for the time lost during ejection during restart after the ejection of a log (8).

Le convertisseur de fréquence fait varier la vitesse de la bande transporteuse (1) en fonction du diamètre des billons (8). The frequency converter varies the speed of the conveyor belt (1) according to the diameter of the logs (8).

Les rampes de décélération de la bande transporteuse (1) sont effectuées avec précision par l'intermédiaire d'un codeur rotatif monté sur le tambour tendeur de la bande transporteuse (1).  The deceleration ramps of the conveyor belt (1) are performed with precision by means of a rotary encoder mounted on the tensioning drum of the conveyor belt (1).

La bande transporteuse (1) ne quitte ni son auge, ni les tambours d'entrainement et de tension au moment des éjections, car, cette dernière est levée autant d'un côté qu'elle baisse de l'autre, il en est de même si plusieurs billons (8) sont éjectés simultanément. En aucun cas la tension de la bande transporteuse (1) n'en sera affectée. The conveyor belt (1) does not leave its trough, nor the drive and tension drums at the time of ejections, because the latter is lifted as much on one side as it drops on the other, so do even if several ridges (8) are ejected simultaneously. In no case will the tension of the conveyor belt (1) be affected.

L'ensemble de mécanique est monolytique. Il est constitué essentiellement d'une poutre (5) avec un chemin de câble (6) et une conduite d'air (7) correspondant à une bonne protection électrique et pneumatique contre les chocs. Ces derniers permettent d'amener l'alimentation électrique et en air d'une façon rationnelle à chaque auge (2) afin qu'elles puissent s'orienter. The mechanical assembly is monolytic. It essentially consists of a beam (5) with a cable tray (6) and an air duct (7) corresponding to good electrical and pneumatic protection against shocks. The latter make it possible to supply the electrical and air supply in a rational manner to each trough (2) so that they can orient themselves.

La dimension des vérins (4) reste relativement faible, le billon (8) à trier étant en équilibre sur ses pivots (3). The dimension of the jacks (4) remains relatively small, the log (8) to be sorted being in equilibrium on its pivots (3).

L'ensemble mécanique, électrique, électropneumatique est géré par un automate ou un microprocesseur. The mechanical, electrical and electropneumatic assembly is managed by an automaton or a microprocessor.

Le dispositif selon l'invention est particulièrement destiné à trier des billons de bois en continu.  The device according to the invention is particularly intended for sorting logs continuously.
