Description

La présente invention a pour objet une installation d'acheminement de pièces de bois, telles que petites grumes ou billes, en vue de leur débit, de leur délignage, de leur refendage, etc ... The subject of the present invention is an installation for conveying pieces of wood, such as small logs or logs, with a view to their throughput, their edging, their slitting, etc.

Plus précisément, la présente invention concerne une installation du type comportant une paire de rails de guidage sur lesquels sont adaptés à coulisser au moins deux chariots porte-grume. More specifically, the present invention relates to an installation of the type comprising a pair of guide rails on which are adapted to slide at least two log carriage carriages.

Les installations de ce type actuellement connues sont destinées aux scieries industrielles et leur structure ne convient que pour des pièces de grandes dimensions. Installations of this type currently known are intended for industrial sawmills and their structure is only suitable for large pieces.

I1 s'ensuit que les artisans ou les particuliers ne disposent d'aucun matériel utilisable et que les grumes ou billes de bois de petit diamètre sont rejetées par les scieries et utilisées comme bois de chauffage. It follows that craftsmen or individuals do not have any usable equipment and that logs or logs of small diameter are rejected by sawmills and used as firewood.

La présente invention a pour but de remédier à cet inconvénient en proposant une installation qui convienne aux pièces de bois de petit diamètre (jusqu'à environ 300 mm), qui puisse être utilisée en combinaison avec tous types de scies, circulaires ou à ruban, qui soit accessible aux artisans et aux particuliers, et dont la mise en oeuvre soit aisée et rapide. The object of the present invention is to remedy this drawback by proposing an installation which is suitable for pieces of wood of small diameter (up to approximately 300 mm), which can be used in combination with all types of saws, circular or band, which is accessible to artisans and individuals, and whose implementation is quick and easy.

Ces buts sont atteints selon l'invention en ce sens que, dans l'installation qu'elle propose, chacun desdits chariots comporte au moins une traverse dont les extrémités opposées coopèrent avec lesdits rails, ladite traverse formant elle-même guide pour un coulisse au prévu à la base d'une potence qui sert à son tour de guide à au moins un croc de serrage, les traverses et les crocs de serrage étant adaptés respectivement à supporter et à s'ancrer dans la pièce de bois. These objects are achieved according to the invention in the sense that, in the installation which it proposes, each of said carriages comprises at least one cross member whose opposite ends cooperate with said rails, said cross member itself forming a guide for sliding at provided at the base of a bracket which in turn serves as a guide for at least one clamping hook, the cross members and the clamping hooks being adapted respectively to support and to anchor in the piece of wood.

On comprend que, de cette manière, le chariot se déplace en translation, par simple poussée, sur les rails, tandis que la potence munie de son ou de ses crocs de serrage se déplace perpendiculairement au sens du déplacement du chariot. It is understood that, in this way, the carriage moves in translation, by a simple push, on the rails, while the bracket provided with its clamping hook (s) moves perpendicular to the direction of movement of the carriage.

De préférence, chaque chariot comporte deux traverses parallèles revêtant la forme de cylindres et reposant, à chacune de leurs extrémités, sur un support commun, chacun desdits supports coopérant avec l'un desdits rails. Preferably, each carriage comprises two parallel crosspieces taking the form of cylinders and resting, at each of their ends, on a common support, each of said supports cooperating with one of said rails.

Pour donner une stabilité irréprochable à l'ensemble, l'un des supports est muni de deux galets qui coopèrent avec le rail adjacent, tandis que l'autre support n'est muni que d'un galet pour coopérer avec son rail. To give impeccable stability to the assembly, one of the supports is provided with two rollers which cooperate with the adjacent rail, while the other support is provided only with a roller to cooperate with its rail.

Pour obtenir un déplacement transversal très progressif du coulisseau, celui-ci est, de préférence, en prise avec une vis sans fin qui est soumise à un organe de commande et qui s'étend d'un support à l'autre. To obtain a very gradual transverse movement of the slide, the latter is preferably engaged with an endless screw which is subjected to a control member and which extends from one support to the other.

Le croc de serrage est monté mobile en translation verticale et/ou horizontale sur la potence, ce qui permet d'adapter sa position à la dimension de la pièce de bois. The clamping hook is mounted movable in vertical and / or horizontal translation on the stem, which makes it possible to adapt its position to the size of the piece of wood.

De préférence, chaque chariot comporte deux crocs de serrage en vis-à-vis définissant ainsi une mâchoire de serrage. Preferably, each carriage has two clamping hooks facing each other, thus defining a clamping jaw.

Pour permettre l'obtention de produits finis d'épaisseur contrôlée, la ou l'une des traverses de chaque chariot porte(nt) une graduation et le coulisseau est muni d'un index de repèrage susceptible de venir en correspondance avec les degrés de ladite graduation. To allow the obtaining of finished products of controlled thickness, the or one of the crosspieces of each carriage carries (s) a graduation and the slide is provided with a locating index capable of coming into correspondence with the degrees of said graduation.

De préférence, les rails sont montés sur des pieds télescopiques, ce qui permet de leur donner une horizontalité parfaite. Preferably, the rails are mounted on telescopic legs, which makes it possible to give them perfect horizontality.

Une forme d'exécution de l'invention est décrite ci-après par référence aux dessins annexés dans lesquels
- la figure 1 est une vue en perspective de l'installation selon l'invention,
- la figure 2 est une vue en bout d'un chariot selon l'invention, et
- la figure 3 est une vue en perspective d'un chariot identique à celui de la figure 2.
An embodiment of the invention is described below with reference to the accompanying drawings in which
FIG. 1 is a perspective view of the installation according to the invention,
FIG. 2 is an end view of a carriage according to the invention, and
FIG. 3 is a perspective view of a carriage identical to that of FIG. 2.

Si l'on se réfère à la figure 1, on voit que l'installation comporte deux rails de guidage 1 réunis par des entretoises 2 et soutenus par des pieds télescopiques 3. Referring to FIG. 1, it can be seen that the installation comprises two guide rails 1 joined by spacers 2 and supported by telescopic feet 3.

Deux chariots désignés dans leur ensemble par la référence 4 sont montés sur les rails 1. Leur structure sera décrite en détail à propos des figures 2 et 3. La référence 5 désigne la position d'une scie à ruban ou d'une scie circulaire classique. Ainsi qu'il ressort encore de la figure 1, il est prévu, en aval de la position de la scie 5, une table de réception 6 dont l'un des couples de pieds est constitué par certains des pieds télescopiques 3 des rails eux-mêmes.Two trolleys designated as a whole by the reference 4 are mounted on the rails 1. Their structure will be described in detail with reference to FIGS. 2 and 3. The reference 5 designates the position of a band saw or of a conventional circular saw . As can also be seen in FIG. 1, there is provided, downstream of the position of the saw 5, a receiving table 6 one of the pairs of feet of which consists of some of the telescopic feet 3 of the rails themselves same.

Si l'on se réfère aux figures 2 et 3, on voit que chaque chariot est constitué d'un couple de supports 7a, 7b de longueurs différentes, le support 7a étant muni de deux galets 8 tandis que le support 7b n'est muni que d'un galet 8. Trois points n'engendrant qu'un plan, ce système garantit la stabilité du chariot. Le support 7b, avec ses deux galets 8 est destiné à être placé sous la charge (figure 2). Comme il ressort en particulier de cette figure 2, les rails 1 sont constitués de profilés en "C" relativement fermés, de sorte que les galets 8 doivent être enfilés par lrextrémité des rails et ne peuvent s'en échapper latéralement ce qui évite tout risque de déraillement des chariots et donc limite les possibilités d'accident. If we refer to Figures 2 and 3, we see that each carriage consists of a pair of supports 7a, 7b of different lengths, the support 7a being provided with two rollers 8 while the support 7b is not provided that of a roller 8. Three points generating only one plane, this system guarantees the stability of the carriage. The support 7b, with its two rollers 8 is intended to be placed under the load (Figure 2). As can be seen in particular from this FIG. 2, the rails 1 are made up of relatively closed "C" profiles, so that the rollers 8 must be threaded through the end of the rails and cannot escape from them laterally, which avoids any risk. derailment of the trucks and therefore limits the possibility of accidents.

Sur les supports 7a et 7b reposent deux traverses 9 dont l'une porte une graduation 10. Les traverses 9 servent de guides cylindriques à un coulisseau 11 supportant une potence 12 servant elle-même de guide à deux bagues respectivement 13a et 13b qui sont en prise respectivement avec des vis sans fin 14a et 14b parallèles à la potence 12 pour former des systèmes d'avance vis-écrou. Aux bagues 13a et 13b sont soudées deux autres bagues 15a et 15b orientées orthogonalement aux précédentes. Dans les bagues 15a et 15b sont respectivement montés coulissants deux bras 16a et 16b munis d'un croc de serrage 17a, 17b.Les bras 16a et 16b présentent une série de perforations 18 susceptibles de venir en correspondance avec une perforation 19-prévue dans la bague 15a, 15b et une goupille 20 fixée à l'extrémité d'une chainette 21 est susceptible de pénétrer à la fois dans la perforation 19 et une perforation 18 pour immobiliser les bras 16a et 16b dans la position voulue par rapport à la potence 12. On the supports 7a and 7b rest two crosspieces 9, one of which carries a graduation 10. The crosspieces 9 serve as cylindrical guides to a slide 11 supporting a bracket 12 itself serving as a guide for two rings respectively 13a and 13b which are in taken respectively with endless screws 14a and 14b parallel to the bracket 12 to form screw-nut advance systems. To the rings 13a and 13b are welded two other rings 15a and 15b oriented orthogonally to the previous ones. In the rings 15a and 15b are slidably mounted two arms 16a and 16b provided with a clamping hook 17a, 17b. The arms 16a and 16b have a series of perforations 18 capable of coming into correspondence with a perforation 19-provided in the ring 15a, 15b and a pin 20 fixed to the end of a chain 21 is capable of penetrating both the perforation 19 and a perforation 18 to immobilize the arms 16a and 16b in the desired position relative to the bracket 12 .

Le coulisseau 11 vient en prise avec une vis sans fin 24 parallèle aux traverses 9 et allant du support 7a au support 7b pour former un système d'avance vis-écrou. Le coulisseau 11 est muni d'un repère 22 qui coopère avec la graduation 10. Une manivelle 23 amovible est adaptée à venir en prise avec la vis sans fin 24 pour déplacer horizontalement le coulisseau 11 avec la potence qu'il supporte, ainsi qu'avec les vis sans fin 14a et 14b pour déplacer vertica-lement les bras 16a et 16b munis de leurs crocs de serrage 17a et 17b. On comprend ainsi qu'il est possible d'effectuer un. règlage grossier en faisant coulisser les bras 16a et 16b dans les bagues 15a et 15b puis de parfaire le règlage horizontalement par déplacement du coulisseau 11 et verticalement par déplacement des bagues 13a et 13b. The slide 11 engages an endless screw 24 parallel to the crosspieces 9 and going from the support 7a to the support 7b to form a screw-nut advance system. The slide 11 is provided with a mark 22 which cooperates with the graduation 10. A removable crank 23 is adapted to come into engagement with the worm screw 24 for horizontally moving the slide 11 with the bracket which it supports, as well as with the endless screws 14a and 14b to vertically move the arms 16a and 16b provided with their clamping hooks 17a and 17b. It is thus understood that it is possible to carry out a. coarse trimming by sliding the arms 16a and 16b in the rings 15a and 15b then perfecting the trimming horizontally by moving the slider 11 and vertically by moving the rings 13a and 13b.

Selon la nature et la forme de la pièce de bois en jeu, on peut n'utiliser que le croc supérieur 17a. Dans ce cas, on ôte la goupille 20 et extrait totalement le bras 16b de la bague 15b. Depending on the nature and shape of the piece of wood involved, only the upper hook 17a can be used. In this case, the pin 20 is removed and the arm 16b is completely removed from the ring 15b.

Comme il ressort de la description qui précède, la présente invention apporte une installation utilisant deux chariots indépendants l'un de l'autre et dont l'écartement peut être adapté à la longueur des pièces de bois utilisées. As emerges from the above description, the present invention provides an installation using two carriages independent of each other and whose spacing can be adapted to the length of the pieces of wood used.

Si les pièces sont très longues, il est possible d'utiliser un troisième chariot du même type. On peut également envisager de prolonger le chemin de roulement par adjonction rapide de tronçons de rail supplémentaires.If the parts are very long, it is possible to use a third trolley of the same type. It is also possible to envisage extending the raceway by rapid addition of additional rail sections.

L'installation selon l'invention contribue à améliorer la rentabilité de la filière bois par utilisation de pièces qui, jusqu'ici, étaient rejetées en raison de leurs dimensions insuffisantes.  The installation according to the invention contributes to improving the profitability of the wood industry by using parts which, up to now, have been rejected due to their insufficient dimensions.
