Description
La présente invention concerne une machine pour effiler les poteaux en bois,selon une forme pyramidale.Ce travail, surtout lorsque les poteaux ont des noeux,demande une force instantanée importante. The present invention relates to a machine for tapering wooden posts, in a pyramidal shape. This work, especially when the posts have knots, requires a large instantaneous force.
Les machines existantes ont donc,soit des moteurs de forte puissance et de forte consommation, soit des systèmes de démultiplication qui rendent le travail lent et diminuent le rendement. Existing machines therefore have either high-power, high-consumption motors or gear reduction systems which make work slow and reduce efficiency.
Le dispositif selon l'invention permet de réaliser une machine de puissance et de consommation modérées tout en assurant une cadence de travail et un rendement élevés. The device according to the invention makes it possible to produce a machine of moderate power and consumption while ensuring a high rate of work and efficiency.
Il comporte,en effet,selon une première caractéristique,un arbre mu par un moteur ou une prise de force,relié à un-arbre intermédiaire possédant un volant d'inertie doté d'une vitesse et d'une masse suffisantes pour emmagasiner l'énergie cinétique nécessaire à l'effilage des poteaux.L'arbre intermédiaire est relié par une démultiplication à un système bielle manivelle qui assure le déplacement d'une paire de couteaux guidés par des barres horizontales,les barres fai- sant entre elles un angle réglable manuellement,égal à l'angle d'effilage des poteaux. According to a first characteristic, it comprises a shaft driven by a motor or a power take-off, connected to an intermediate shaft having a flywheel endowed with a speed and a mass sufficient to store the kinetic energy necessary for the tapering of the posts. The intermediate shaft is connected by a reduction in a crank rod system which ensures the displacement of a pair of knives guided by horizontal bars, the bars making between them an adjustable angle manually, equal to the taper angle of the posts.
L'utilisateur place un poteau sur la table en V de la machine,il pousse le poteau qui appuie par son extrémité à effiler, sur une plaque de commande,celle-ci enclenche,par l'intermédiaire d'une fourchette reliée à une barre de manoeuvre,un embrayage à crabots. The user places a pole on the V-shaped table of the machine, he pushes the pole which presses by its end to be tapered, on a control plate, this engages, by means of a fork connected to a bar maneuver, a dog clutch.
le volant qui est relié directement à l'arbre moteur, tourne de façon continue,l'arbre-manivelle,lui même,ne tourne que lorsque l'embrayage est er-clanché,entrainant ainsi les couteaux uniquement lorsque le poteau est dans sa position d'effilage. the flywheel which is directly connected to the motor shaft, rotates continuously, the crankshaft itself only rotates when the clutch is er-engaged, thus driving the knives only when the post is in its position tapering.
L'arbre-manivelle ayant effectué un tour,les couteaux reviennent en position arrière,ramenant par l'intermédiaire d'une barre de manoeuvre,la saque de commande à sa position initiale,assurant ainsi le débr2yage. The crankshaft having made a revolution, the knives return to the rear position, bringing back by means of an operating bar, the control plate to its initial position, thus ensuring the unclogging.
A ce moment,les couteaux étant arrêtés,l'utilisateur fait tourner le poteau de 900 appuyant à nouveau sur la plaque de commande et assurant un deuxième effilage donnant la forme pyramidale.Pour.que la plaque de commande puisse revenir en avant bien qu'elle soit tenue en arrière par la barre de manoeuvre,elle même tenue par les portes couteaux en position arrière,un ressort taré sera placé entre la butée arrière de la barre de manoeuvre et une bague coulissante en contact avec la partie arrière des portes couteaux.Le ressort sera suffisamment dur pour permettre sans s'écraser le recul de la plaque de commande,suffisamment souple pour permettre l'avance de la dite plaque sans effort excessif de l'utilisateur. At this moment, the knives being stopped, the user turns the post by 900 pressing again on the control plate and ensuring a second tapering giving the pyramidal shape. So that the control plate can come back forward although it is held back by the operating bar, itself held by the knife doors in the rear position, a calibrated spring will be placed between the rear stop of the operating bar and a sliding ring in contact with the rear part of the knife doors. The spring will be hard enough to allow the backing of the control plate to be crushed without being crushed, flexible enough to allow said plate to advance without excessive effort by the user.
Selon des modes particuliers de réalisation - l'arbre-manivelle peut avoir deux manivelles symétriques reliées chacune par une bielle à chacun des deux couteaux, les. pieds et têtes de bielles étant constitués par des rotules. According to particular embodiments - the crank shaft can have two symmetrical cranks each connected by a connecting rod to each of the two knives,. feet and rod ends being formed by ball joints.
- l'arbre moteur peut être relié à l'arbre intermédiaire par courroies;ce dernier étant relié à l'arbre-manivelle par chaîne afin d'éviter tout patinage.- the drive shaft can be connected to the intermediate shaft by belts; the latter being connected to the crankshaft by chain to avoid slippage.

La figure 2 représente,en vue de dessus,le même dispositif.Figure 2 shows, in top view, the same device.
En référence à ces dessins,le dispositif comporte un chassis (1) sur lequel est fixé un arbre d'entrainement (2) relié par une courroie (3) à un arbre intermédiaire (4) portant une poulie volant d'inertie (5),un embrayage à crabots (6) permet d'accoupler le volant d'inertie (5) à un pignon (7) tournant fou sur l'arbre intermédiaire (4). With reference to these drawings, the device comprises a chassis (1) on which is fixed a drive shaft (2) connected by a belt (3) to an intermediate shaft (4) carrying a flywheel pulley (5) , a dog clutch (6) makes it possible to couple the flywheel (5) to a pinion (7) turning idly on the intermediate shaft (4).
Le pignon (7) est relié par une chaise (8) à une roue dentée (9) solidaire de l'arbre-manivelle (10).L'arbre-manivelle possède deux manivelles (11-12) qui actionnent les bielles (13-14) assurant l'entrainement des portes couteaux (15-16),les pieds et têtes de bielles sont constitués par des rotules (17-18-19-20).Les portes couteaux coulissent sur les barres horizontales (21-22-23-24) qui font entre elles un angle réglable,égal à l'angle d'effilage des poteaux (25). The pinion (7) is connected by a chair (8) to a toothed wheel (9) integral with the crank shaft (10). The crank shaft has two cranks (11-12) which actuate the connecting rods (13 -14) ensuring the drive of the knife holders (15-16), the feet and connecting rod heads consist of ball joints (17-18-19-20). The knife doors slide on the horizontal bars (21-22- 23-24) which form an adjustable angle between them, equal to the taper angle of the posts (25).
Une table en V (26) sert de support au poteau (25) à effiler.Une plaque de commande (27) pivotant sur un arbre (28) est solidaire par un axe (29) d'une barre de manoeuvre (30),celle-ci par ltintermédiaire d'une fourchette (31), embraye le crabot (6) en avançant ou le débraye en reculant. A V-shaped table (26) serves as a support for the post (25) to be tapered. A control plate (27) pivoting on a shaft (28) is secured by an axis (29) to an operating bar (30), the latter by means of a fork (31) engages the dog clutch (6) by advancing or disengages it by reversing.
Une butée (32) à l'arrière de la barre de manoeuvre est rendue élastique par l'intermédiaire d'un ressort taré (33) et d'une bague coulissante (34).En reculant le bloc porte couteau (15) prend appui sur la bague coulissante (34)-et fait reculer la barre de manoeuvre (30). A stop (32) at the rear of the operating bar is made elastic by means of a calibrated spring (33) and a sliding ring (34). By moving back the knife holder block (15) is supported on the sliding ring (34) -and moves back the operating bar (30).
Le dispositif selon l'invention est particulièrement destiné à l'effilage des poteaux en bois. The device according to the invention is particularly intended for tapering wooden posts.
