Description

La présente invention concerne une machine de fendage de bois à cône fileté rotatif et, plus particulièrement, un dispositif de protection de l'utilisateur vis-à-vis de la pointe du cône fileté.The present invention relates to a wood splitting machine with a rotary threaded cone and, more particularly, a device for protecting the user from the tip of the threaded cone.

Des machines de fendage de bois à cône fileté rotatif sont connues. Parmi celles-ci, on peut mentionner la machine décrite dans la demande de brevet européen EP-A-0 124 466 déposée le 25 avril 1984 par le présent demandeur. Cette machine est constituée d'une caisse montée sur pieds avec, à l'intérieur de la caisse, un cône fileté dirigé vers le bas et supporté, sous le paroi supérieure de celle-ci, par son arbre moteur, une plaque support de bûche portée, au-dessus de la paroi inférieure, sous le cône fileté, par des moyens ascenseurs commandables, la caisse comportant une porte dans une de ses parois verticales dont l'ouverture coupe les moyens d'entraînement du cône rotatif.Wood splitting machines with rotary threaded cone are known. Among these, mention may be made of the machine described in European patent application EP-A-0 124 466 filed on April 25, 1984 by the present applicant. This machine consists of a box mounted on legs with, inside the box, a threaded cone directed downwards and supported, under the upper wall thereof, by its motor shaft, a log support plate carried, above the lower wall, under the threaded cone, by controllable elevator means, the body comprising a door in one of its vertical walls, the opening of which cuts the means for driving the rotary cone.

Cette machine est entièrement satisfaisante en ce qui concerne la sécurité de l'utilisateur. Toutefois, elle représente un matériel assez sophistiqué, donc cher, pour une partie de la clientèle potentielle. D'autre part, comme le cône fileté se trouve à l'intérieur d'un espace limité, seules des bûches calibrées peuvent être traitées.This machine is entirely satisfactory with regard to user safety. However, it represents fairly sophisticated equipment, therefore expensive, for part of the potential clientele. On the other hand, as the threaded cone is located within a limited space, only calibrated logs can be processed.

Une machine plus simple, constituée d'une table au-dessus de laquelle tourne un cône fileté à axe horizontal, est décrite dans le document FR-A-2 415 524. Elle est équipée d'un dispositif empêchant les contacts involontaires avec la pointe. Ce dispositif est constitué par une palette verticale qui est fixée sur un bras pivotant et qui passe dans une rainure prévue dans le plateau de la table. Un moyen élastique pousse la palette vers le haut, un des bords de la palette se trouvant tout près de la pointe. Lorsqu'elle est poussée vers le bas, par la base d'une bûche, la palette dégage la pointe et, juste avant que la bûche n'ait été traversée de part en part, la palette remonte à sa position haute initiale.A simpler machine, consisting of a table above which rotates a threaded cone with a horizontal axis, is described in document FR-A-2 415 524. It is equipped with a device preventing involuntary contact with the tip . This device consists of a vertical pallet which is fixed on a pivoting arm and which passes through a groove provided in the table top. An elastic means pushes the pallet upwards, one of the edges of the pallet being very close to the point. When pushed down from the base of a log, the pallet releases the point and, just before the log has been passed right through, the pallet returns to its initial high position.

Pour mettre les bûches en place sur une telle machine, il faut les élever au-dessus de la palette, c'est-à-dire bien au-dessus du niveau de la table, ce qui représente un effort non négligeable au bout d'un certain temps de travail.To put the logs in place on such a machine, they must be raised above the pallet, that is to say well above the level of the table, which represents a significant effort after some working time.

Un objet de la présente invention consiste à prévoir un dispositif de sécurité sur une machine comportant un cône fileté rotatif au-dessus d'une table de travail, qui soit efficace, simple et qui ne demande pas d'effort particulier de la part de l'utilisateur.An object of the present invention is to provide a safety device on a machine comprising a rotating threaded cone above a work table, which is efficient, simple and which does not require any particular effort on the part of the user. 'user.

Selon une caractéristique de l'invention, la machine, comprenant un cône à axe de rotation horizontal monté au-dessus d'une table, comporte un tube fixe, parallèle à l'axe du cône, dans lequel est montée coulissante une partie d'un bras dont l'autre partie, coudée, a son extrémité qui fait face à la pointe du cône, ladite extrémité se déplaçant entre une position très rapprochée et une position éloignée de la pointe quand le bras coulisse dans le tube, un moyen maintenant ladite extrémité sur l'axe du cône lors du coulissement et un moyen ressort rappelant continuellement ladite extrémité dans la position très rapprochée de la pointe.According to a characteristic of the invention, the machine, comprising a cone with horizontal axis of rotation mounted above a table, comprises a fixed tube, parallel to the axis of the cone, in which a part of an arm of which the other part, bent, has its end which faces the point of the cone, said end moving between a very close position and a position distant from the point when the arm slides in the tube, a means maintaining said end on the axis of the cone during sliding and a spring means continuously recalling said end in the very close position of the tip.

Selon un mode particulier de réalisation de cette invention, le moyen maintenant ladite extrémité du bras sur l'axe du cône pehdant le coulissement est constitué par une rainure longitudinale dans une des parois du tube et une saillie sur la partie du bras qui coulisse à l'intérieur du tube, la saillie étant engagée dans ladite rainure.According to a particular embodiment of this invention, the means maintaining said end of the arm on the axis of the cone during sliding is constituted by a longitudinal groove in one of the walls of the tube and a projection on the part of the arm which slides at inside the tube, the projection being engaged in said groove.

Selon une autre mode de réalisation de l'invention, la section du tube est carrée et la section du bras est ronde, de diamètre sensiblement égal à la longueur du côté interne de la section du tube, et ladite rainure est prolongée perpendiculairement, à son extrémité correspondant à la position la plus éloignée de l'extrémité libre du bras par rapport à la pointe, par une rainure par laquelle la saillie peut rentrer à l'intérieur du tube, permettant au bras d'être dégagé sur le côté de la table pour placer les bûches ou en traiter particulièrement grosses.According to another embodiment of the invention, the section of the tube is square and the section of the arm is round, of diameter substantially equal to the length of the internal side of the section of the tube, and said groove is extended perpendicularly to its end corresponding to the position furthest from the free end of the arm relative to the point, by a groove through which the projection can enter the inside of the tube, allowing the arm to be released on the side of the table for placing logs or treating particularly large ones.

En variante, selon une autre mode de réalisation de l'invention, le moyen maintenant ladite extrémité du bras sur l'axe du cône pendant le coulissement est constitué par un second bras fixé par une extrémité au premier et dont la partie adjacente à l'autre extrémité est parallèle à l'axe du cône et est montée coulissante dans un second tube fixe.As a variant, according to another embodiment of the invention, the means maintaining said end of the arm on the axis of the cone during sliding consists of a second arm fixed by one end to the first and whose part adjacent to the other end is parallel to the axis of the cone and is slidably mounted in a second fixed tube.

Selon une autre mode de réalisation de l'invention, les tubes de coulissement des deux bras se trouvent de chaque côté de la table.According to another embodiment of the invention, the sliding tubes of the two arms are located on each side of the table.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:

  • la Fig. 1 est une vue en perspective d'une machine selon l'invention, et
  • la Fig. 2 est une vue agrandie du système de coulissement du bras, une bûche étant représentée entre l'extrémité libre du bras et la pointe du cône.
The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
  • Fig. 1 is a perspective view of a machine according to the invention, and
  • Fig. 2 is an enlarged view of the sliding system of the arm, a log being shown between the free end of the arm and the tip of the cone.

La machine, Fig. 1, comporte une armature constituée de fers ronds soudés entre eux. Un premier fer rond 1, en forme de U, délimite les deux côtés latéraux 2 et 3 et le côté avant 4 d'une table de travail rectangulaire dont le plateau 5 est une plaque en tôle fixée au côtés 2, 3 et 4. Sous la base du fer en U 1, est soudé un pied vertical 6.The machine, Fig. 1, comprises a frame made up of round bars welded together. A first round iron 1, in the shape of a U, delimits the two lateral sides 2 and 3 and the front side 4 of a rectangular work table, the plate 5 of which is a sheet metal plate fixed to the sides 2, 3 and 4. Under the base of the U-shaped iron 1 is welded to a vertical foot 6.

Les extrémités du fer en U 1 sont soudées aux branches verticales 8 et 9 d'un cadre 7 également en fer rond, près de son côté inférieur 10. Une traverse entre les branches 8 et 9, juste sous le niveau du plateau 5 de la table peut être prévue pour assurer la rigidité du côté arrière de celui-ci. Le cadre 7 a un côté supérieur 11.The ends of the U-shaped iron 1 are welded to the vertical branches 8 and 9 of a frame 7 also made of round iron, near its lower side 10. A crosspiece between the branches 8 and 9, just below the level of the plate 5 of the table can be provided to ensure the rigidity of the rear side thereof. The frame 7 has an upper side 11.

Les côtés 8 et 9 sont prolongés vers le bas par deux pieds arrière tels que 12. Les pieds arrière 12, ainsi que le pied avant 6, peuvent être prévus télescopiques.The sides 8 and 9 are extended downwards by two rear feet such as 12. The rear feet 12, as well as the front foot 6, can be provided telescopic.

Le cadre 7 porte un ensemble 13 supportant le moteur d'entraînement d'un cône fileté rotatif 14 disposé au-dessus de la table de travail dont l'axe de rotation horizontal est parallèle aux côtés 2 et 3.The frame 7 carries an assembly 13 supporting the motor for driving a rotary threaded cone 14 disposed above the work table, the horizontal axis of rotation of which is parallel to the sides 2 and 3.

Le long du côté 2, à partir de l'arrière et sur une certaine longueur, est fixé un tube creux de section carrée 15. La face verticale externe du tube 15 comporte une lumière longitudinale 16 sur une grande partie de sa longueur. La lumière 16 est parallèle au côté 2 et, par conséquent, à l'axe du cône rotatif 14.Along the side 2, from the rear and over a certain length, is fixed a hollow tube of square section 15. The external vertical face of the tube 15 has a longitudinal lumen 16 over a large part of its length. The light 16 is parallel to the side 2 and, consequently, to the axis of the rotary cone 14.

Un bras 17 de section ronde est monté coulissant dans le tube 15. La section du bras 17 a un diamètre sensiblement égal à la longueur des côtés intérieur du tube 15, de façon que le bras 17 soit enfilé sans jeu dans le tube 15. Près de son extrémité arrière qui se trouve dans le tube 15, le bras 17 comporte une saillie 18 engagée dans la lumière 16. La saillie 18 est sensiblement de la même largeur que la lumière 16 pour empêcher le pivotement du bras 17. La partie du bras 17 extérieure au tube 15 est coudée en plusieurs endroits pour passer au-dessus du niveau de la table et finir en une portion rectiligne alignée avec l'axe du cône 14 quand la saillie 18 est dans la lumière 16. A la Fig. 1, elle comprend, après un premier coude, une portion verticale, une portion horizontale perpendiculaire à l'axe de rotation du cône 14 et ladite portion alignée avec l'axe du cône 14. En pratique, l'utilisateur saisit le bras 17 à l'endroit de la portion verticale ou de la portion horizontale perpendiculaire à l'axe du cône. Lorsque la saillie 18 se trouve à l'extrémité arrière de la lumière 16, l'extrémité 19 du bras 17 de trouve en face et très près de la pointe du cône 14. Afin de mieux protéger la pointe du cône 14, l'extrémité 19 peut avoir une forme s'évasant vers la pointe.An arm 17 of round section is slidably mounted in the tube 15. The section of the arm 17 has a diameter substantially equal to the length of the inner sides of the tube 15, so that the arm 17 is threaded without play in the tube 15. Close from its rear end which is located in the tube 15, the arm 17 has a projection 18 engaged in the lumen 16. The projection 18 is substantially the same width as the lumen 16 to prevent pivoting of the arm 17. The part of the arm 17 outside the tube 15 is bent in several places to pass above the level of the table and finish in a rectilinear portion aligned with the axis of the cone 14 when the projection 18 is in the lumen 16. In FIG. 1, it comprises, after a first bend, a vertical portion, a horizontal portion perpendicular to the axis of rotation of the cone 14 and said portion aligned with the axis of the cone 14. In practice, the user grasps the arm 17 to the location of the vertical portion or the horizontal portion perpendicular to the axis of the cone. When the projection 18 is at the rear end of the light 16, the end 19 of the arm 17 is opposite and very close to the tip of the cone 14. In order to better protect the tip of the cone 14, the end 19 may have a shape which widens towards the point.

Un ressort 20 dont une extrémité est fixée sous le tube 15 et dont l'autre extrémité est fixée sous le bras 17, près de son premier coude, rappelle l'extrémité 19 près de la pointe du cône 14.A spring 20, one end of which is fixed under the tube 15 and the other end of which is fixed under the arm 17, near its first bend, recalls the end 19 near the tip of the cone 14.

A son extrémité avant, la lumière 16 est prolongée vers le bas. Ainsi, quand la saillie 18 se trouve à l'extrémité avant de la lumière 16, il est possible de dégager le bras 17 par rapport au plan de la table en le faisant pivoter sur le côté, la saillie 18 pénétrant alors dans ledit prolongement de la lumière 16.At its front end, the lumen 16 is extended downward. Thus, when the projection 18 is at the front end of the slot 16, it is possible to release the arm 17 relative to the plane of the table by pivoting it to the side, the projection 18 then penetrating said extension of light 16.

Pour mettre une bûche sur le plateau 5, en face du cône 14, on tire sur le bras 17 jusqu'à ce que la saillie 18 soit à l'extrémité avant de la lumière 16 et on le fait pivoter sur le côté. Le plateau 5 est ainsi dégagé pour placer la bûche. On ramène alors le bras 17 au-dessus de la table. Sous l'action du ressort 20, la saillie 18 s'engage à nouveau dans la lumière 16 proprement dite et la pointe 19 vient en contact avec la partie de la bûche opposée à la pointe du cône. On met l'appareil en route en maintenant la bûche en place au démarrage. Pendant toute l'opération, l'extrémité 19 du bras 17 va se trouver sur l'axe du cône 14, en face de la pointe de celui-ci et rappelée vers elle par le ressort 20, évitant tout risque pour l'utilisateur d'être accroché par ladite pointe.To put a log on the plate 5, opposite the cone 14, pull on the arm 17 until the projection 18 is at the front end of the light 16 and it is rotated to the side. The plate 5 is thus released to place the log. The arm 17 is then brought back above the table. Under the action of the spring 20, the projection 18 engages again in the slot 16 proper and the tip 19 comes into contact with the part of the log opposite the tip of the cone. The appliance is started up by keeping the log in place at start-up. During the whole operation, the end 19 of the arm 17 will be on the axis of the cone 14, opposite the tip of the latter and brought back towards it by the spring 20, avoiding any risk for the user of 'be hooked by said point.

Le fait de pouvoir dégager le bras 17 du plan de la table permet également de traiter des bûches de grandes dimensions.The fact of being able to release the arm 17 from the table plane also makes it possible to process large logs.

On peut, de plus, prévoir une protection latérale du cône 14 au moyen de deux plaques montées pivotantes sur l'ensemble 13. Lesdites plaques convergent l'une vers l'autre en un point situé en avant de la pointe du cône 14 et divergent ensuite jusqu'à leurs extrémités. Les plaques sont écartées par la bûche elle-même qu'on pousse sur la pointe du cône.It is also possible to provide lateral protection for the cone 14 by means of two plates pivotally mounted on the assembly 13. Said plates converge towards one another at a point situated in front of the tip of the cone 14 and diverge then to their ends. The plates are separated by the log itself which is pushed on the tip of the cone.

Enfin, la machine peut être équipée d'un système de roulage classique, fixé à la partie supérieure de la paroi arrière de l'ensemble 13, par exemple. Les pieds arrière 12 peuvent alors servir de bras pour véhiculer la machine à la façon d'une brouette.Finally, the machine can be equipped with a conventional rolling system, fixed to the upper part of the rear wall of the assembly 13, for example. The rear feet 12 can then be used as an arm to transport the machine like a wheelbarrow.

En variante, le tube 15 peut être fixé à gauche de la table ou même sous le plateau 5.As a variant, the tube 15 can be fixed to the left of the table or even under the tray 5.

En variante également, le bras 17, dans sa partie horizontale au-dessus de la table perpendiculaire à l'axe du cône 14, peut être prolongé par un second bras dont une partie adjacente à l'extrémité libre est parallèle à l'axe du cône et montée coulissante dans un tube fixe semblable au tube 15. En pratique, lesdits tubes sont symétriques, par exemple fixés de chaque côté du plateau 5, et les bras forment une seule pièce en forme de portique au-dessus du plateau 5. La partie du bras 17 dans l'alignement de l'axe du cône 14 et comportant l'extrémité de protection 19 est alors supprimée et cette dernière peut être remplacée, par exemple, par un trou borgne dans la partie centrale du portique qui reste forcément dans l'alignement de la pointe du cône 14.Alternatively also, the arm 17, in its horizontal part above the table perpendicular to the axis of the cone 14, can be extended by a second arm, a part adjacent to the free end is parallel to the axis of the cone and sliding mount in a fixed tube similar to tube 15. In practice, said tubes are symmetrical, for example fixed on each side of the plate 5, and the arms form a single piece in the form of a gantry above the plate 5. The part of the arm 17 in alignment with the axis of the cone 14 and comprising the protective end 19 is then removed and the latter can be replaced, for example, by a blind hole in the central part of the gantry which necessarily remains in the alignment of the tip of the cone 14.

Wood splitting machine comprising a threaded cone (14) with a horizontal rotation axis revolving above a table, and characterized by the fact that it also contains a fixed tube (15) which is parallel to the cone axis (14) and in which the sliding part of an arm (17) is fixed, whereas the other part of the arm is bent and has its end (19) facing the cone tip (14). This end (19) moves from a position very close to the tip to a position far from it when the arm (17) slides in the tube (15), whereas a device holds the end in question (19) on the cone axis (14) during the sliding and a spring (20) continually returns this end (19) to the position very close to the tip.
2. Machine as per claim 1, characterized by the fact that the device holding the end (19) of the arm (17) on the cone axis (14) during the sliding consists of a longitudinal groove (16) in one of the tube sides (15) and of a protrusion (18) on the part of the arm (17) which slides in the tube (15), whereby the protrusion (18) is engaged in the groove (16).
3. Machine as per claim 1 or 2, characterized by the fact that the tube section (15) is square and the section of the arm (17) is round and has a diameter appreciably equal to the length of the inner side of the tube section (15), whereas the groove (16) is extended, perpendicularly on its end corresponding to the furthest position from the free end (19) of the arm (17) in relation to the tip, by a groove through which the protrusion (18) can return inside the tube (15), thus allowing the arm (17) to be free on the side of the table to place logs or to treat some particularly big ones.
4. Machine as per claim 1, characterized by the fact that the device holding the end of the arm (17) on the cone axis (14) consists of a second arm which is fixed by one end to the first arm, whereas the part of this second arm which is adjacent to the other end is parallel to the cone axis and is fixed in a second fixed tube in which it slides.
5. Machine as per claim 4, characterized by the fact that the sliding tubes of both arms are situated on either side of the table.
