Abstract

The installation may either be adapted to an existing edging circular sawing machine or comprise the supply of an adapted edging circular sawing machine. The unedge-sawn products of all widths coming from the sawmill or mills are routed by transfer and turned over mechanically in front of the operator of the edge-sawing to allow him to visualise the two faces. The thickness of the product is determined automatically by a set of photoelectric cells. The operator manually determines the quality of the product to be processed, and displays it on a keyboard, the latter remains programmed constantly until the next display. The length of the product is recorded in the same fashion by the operator. He positions the plank in front of the edging circular sawing machine and manually, with the aid of lasers, determines the greatest width, the information is then recorded in the computer which, as a function of the products to be produced and their sale prices, including the price of the sawn off-cuts, will give the order to the saws to position themselves to edge-saw the product for the best commercial and financial yield. The edging circular sawing machine may have two, three or four blades. The installation, which is the subject of the invention, may be used in all sawmills where planks of all widths and fixed width are concerned.

Description

La présente invention concerne l'Optimisation du délignage en scierie, permettant d'obtenir des débits à largeurs fixes à partir de produits toutes largeurs par calcul du meilleur choix commercial et financier en assurant une meilleure rentabilité financière
Dans les installations existantes , l'opération de délignage consiste à obtenir un produit avivé le plus large possible par enlévement des flasches
Les produits de largeur fixe sont issus de noyaux élaborés sur la scie de tête ou sur un refendeur . Cette opération ne permet pas l'élaboration de produits de faibles largeurs sans pénalisation de la productivité de la scierie et génère un rendement matière peu élevé.
The present invention relates to the Optimization of edging in a sawmill, making it possible to obtain fixed-width throughputs from products of all widths by calculating the best commercial and financial choice while ensuring better financial profitability.
In existing installations, the edging operation consists in obtaining the widest edged product possible by removing the flasks
Fixed width products are produced from cores produced on the head saw or on a splitter. This operation does not allow the production of products of small widths without penalizing the productivity of the sawmill and generates a low material yield.

Lors de l'élaboration de largeurs fixes de plus grosses sections ( traverses charpente ) où la rentabilité est préservée , la fabrication du noyau génère des produits de bordures toutes largeurs
Ces produits trouvent difficilement de débouchés , c'est pourquoi les efforts de standardisation de la gamme de produits ont permi de se rapprocher du marché par l'élaboration d'une gamme de produits mieux valorisés , en largeurs fixes
Actuellement ces produits sont rarement fabriqués dans les scieries pour les moyennes et faibles sections , car il y a une incompatibilité entre les possibilités de fabrication du matériel à un niveau de rentabilité normal d'une grande partie de la gamme de largeurs fixes, et le fait que la fabrication de produits de largeurs fixes de dimensions plus importantes génère des produits fatals de relève toutes largeurs qui ne trouvent pas de débouché.
When developing fixed widths of larger sections (frame sleepers) where profitability is preserved, the production of the core generates edging products of all widths
These products hardly find outlets, which is why efforts to standardize the product range have made it possible to get closer to the market by developing a range of better valued products, in fixed widths.
Currently these products are rarely produced in sawmills for medium and small sections, because there is an incompatibility between the possibilities of manufacturing the material at normal profitability level of a large part of the range of fixed widths, and the fact that the manufacture of products of fixed widths of larger dimensions generates fatal products of relief of all widths which do not find an outlet.

La présente invention permet de fabriquer des produits largeurs fixes de petites et moyennes dimensions , en fonction des commandes à partir de produits toutes largeurs sans pénaliser la productivité , le rendement matière , en conservant les méthodes de débits traditionnelles au niveau du métier de tête et du refendeur tout en assurant une meilleure rentabilité financière
Cette optimisation commerciale et financière est réalisée par un calculateur qui enregistre les produits et les quantités à fabriquer assorties de leurs prix de vente .Chaque planche est mesurée avant le délignage en dimension toute largeur le calculateur en fonction des commandes recherchera la meilleure solution de débit en comparant la solution toute largeur à la meilleure solution largeur fixe en commande , dans le calcul la chute occasionnée par une solution largeur fixe est comptabilisée au prix de vente des délignures , ou suivant la dimension au prix d'un deuxième produit largeur fixe en commande
L'installation peut être soit adaptée sur une déligneuse existante soit comprendre la fourniture d'une déligneuse adaptée.
The present invention makes it possible to manufacture fixed width products of small and medium dimensions, according to orders from products of all widths without penalizing productivity, material yield, while preserving the traditional flow methods at the level of the head profession and the reseller while ensuring better financial profitability
This commercial and financial optimization is carried out by a calculator which records the products and the quantities to be produced with their selling prices. Each board is measured before trimming in any width dimension the calculator according to the orders will seek the best flow solution in comparing the full width solution to the best fixed width solution on order, in the calculation the fall caused by a fixed width solution is accounted for at the selling price of the edging, or according to the dimension at the price of a second fixed width product on order
The installation can either be adapted on an existing edger or include the supply of an adapted edger.

Les produits flascheux toutes largeurs issus du ou des métiers à scier sont acheminés par transfert et retournés mécaniquement devant l'opérateur du delignage pour lui permettre de visionner les deux faces .The flaccid products of all widths coming from the sawing loom (s) are conveyed by transfer and returned mechanically in front of the edging operator to allow him to view both sides.

L'épaisseur du produit est déterminée automatiquement par un ensemble de cellules photo-électriques. L'opérateur détermine manuellement la qualité du produit à traiter, et l'affiche sur un clavier , celle-ci restera programée constamment jusqu'au prochain affichage. La longueur du produit est enregistré de la même façon par l'opérateur .Il positionne la planche devant la déligneuse et manuellement à l'aide de lasers détermine la plus grande largeur , l'information est alors enregistrée dans le calculateur qui, en fonction des produits à réaliser et de leurs prix de vente, en intégrant pour les chutes le prix des délignures donnera l'ordre aux scies de se positionner pour déligner le produit au meilleur rendement commercial et financier .La déligneuse pourra être à deux , trois ou quatre lames
Le calculateur effacera du programme les commandes réalisées et sur une période communiquera le point des commandes en quantités, volumes ainsi que le résultat financier de son choix par rapport à la solution toute largeur
Cette application sera évolutive en particulier par la possibilité d'introduire automatiquement les produits dans la déligneuse, de déterminer automatiquement leurs formes et leurs qualités, et leurs dimensions toutes largeurs Les produits délignés pourront être dirigés automatiquement vers des box de triage ou de réempilage à partir de l'enregistrement de la ou des dimensions délignées
L'enregistrement des produits débités au niveau du ou des métiers de tête et non dirigés vers ladéligneuse permettra la mise en place d'une gestion informatisée pour l'ensemble de la scierie
L'installation , objet de l'invention peut être utilisée dans toutes les scieries dès lors qu'il s'agit de planches toutes largeurs et largeurs fixes
The thickness of the product is automatically determined by a set of photocells. The operator manually determines the quality of the product to be treated, and displays it on a keyboard, which will remain programmed constantly until the next display. The length of the product is recorded in the same way by the operator. He positions the board in front of the edger and manually using lasers determines the largest width, the information is then recorded in the calculator which, depending on the products to be produced and their selling prices, by integrating the price of edging for scrap, will order the saws to position themselves to edging the product at the best commercial and financial return. The edger can be two, three or four blades
The calculator will erase from the program the orders placed and over a period will communicate the point of the orders in quantities, volumes as well as the financial result of its choice compared to the full width solution
This application will be scalable in particular by the possibility of automatically introducing the products into the edger, of automatically determining their shapes and their qualities, and their dimensions in all widths. The outlined products can be automatically directed to sorting or re-stacking boxes from the registration of the outlined dimension (s)
The recording of the products debited at the level of the head trade (s) and not directed to the grinder will allow the implementation of a computerized management for the whole sawmill
The installation, object of the invention can be used in all sawmills when it comes to boards of all widths and fixed widths
