Abstract

The appts. is used for making wooden structures which can include composite beams. The beams are advanced on rollers underneath an adhesive distributor blade sloping in the direction of travel, and swinging about an axis at right angles to the direction of travel. The blade carries a valve with a supply tube attached, connecting the adhesive supply to the discharge holes at the lip of the blade. The blade is attached to a boss with a lug projecting from it, which is p shed upwards by a spring underneath, holding the tip of the blade in contact with the wood. When the end of the wood is reached, the spring tilts the blade so that the lug operates a switch which cuts off the adhesive supply. Above the lug is an adjusting screw. The ingredients pass through a dispensing and mixing unit with connections for compressed air and interconnected with a control unit. The switch operates in conjunction with a photoelectric cell in which a luminous ray is interrupted by the traject of the workpieces.

Description

Le présent certificat d'addition ee rattache au brevet principal qui concerne, d'une façon générale, les produits collante composés d'une résine et de aon durcisseur ; il a trait plus particulièrelent â une installation permettant simultanément le mélange, le dosage et son application, dans des proportions bien définies, d'une façon continue et automatique, sur des piè- ces de bois lises en oeuvre pour les techniques des poutre. en bois lamellé cellé, du panneautage et de l'about ge.  This certificate of addition is attached to the main patent which relates, in general, to sticky products composed of a resin and a hardener; it relates more particularly to an installation allowing simultaneous mixing, dosing and its application, in well defined proportions, in a continuous and automatic manner, on pieces of wood used for beam techniques. in laminated wood, paneling and end fittings.

Selon le brevet principal, la dépose automatique des cordons de colle sur une pièce de bois on nouvesent, est assuré par un sabot oscillant situé au-dessus de celle-cl. Lorsqu'il est soulevé par la pièce de bols, il asu- mande l'auverture des clapete pneumatiques d'admission et la formature des même clapets, lorsque le bec du sabot échappe á la pièce de bois. According to the main patent, the automatic removal of the beads of glue on a piece of wood is new, is provided by an oscillating shoe located above it. When it is lifted by the bowl, it assumes the opening of the pneumatic intake valves and the form of the same valves, when the shoe spout escapes from the piece of wood.

Ce dispositif présente un inconvénient lorsque le bois á encoller a une grande vitesse d'avancement. En effet, entre le moment où l'impulsion électrique est donnée par le micro-rupteur et celui où la colle sort du bec du sabot, il s'écoule une fraction de seconde correspondant au temps de réponse du système. Pendant cette période la pièce de bois a dépassé le bec du sabo- d'une certaine longueur ; de ce fait, cette partie ne recevra pas de colle. This device has a drawback when the wood to be glued has a high speed of advance. Indeed, between the moment when the electrical impulse is given by the micro-switch and that when the glue comes out of the shoe's beak, a fraction of a second elapses corresponding to the response time of the system. During this period the piece of wood exceeded the beak of the sabo by a certain length; therefore, this part will not receive glue.

Selon un pressier perfectionnement, le sicro-rupteur n'est plus acon- conandé par le sabot encoller, mais par la pièce de bois elle-même. Pour ce faire le licro-rupteur est placé de telle façon que la pièce de bois l'actionne lors de mon passage. I1 est placé en anont du sabot, à une dis- tance telle qu le temps de réponse du système corresponds à celui ais par la pièce de bois pour arriver au sabot oncolleur, après avoir écrasé * le sicro- rupteur.Cette distance correspond bien entendu A une certaine vitesse d'avaa cessent de la planche ; si elle varie, le sicro-ripteur doit être déplacé d'ans longueur proportionnelle å celle-ci.  According to an advanced press maker, the micro-switch is no longer supported by the glue shoe, but by the piece of wood itself. To do this, the halter switch is placed in such a way that the piece of wood activates it during my passage. It is placed in front of the hoof, at a distance such that the response time of the system corresponds to that taken by the piece of wood to arrive at the adhesive hoof, after having crushed * the micro-switch. This distance corresponds of course At a certain speed, the board stops; if it varies, the micro-ripteur must be moved in length proportional to this.

Lorsque la partie arrière de la planche libère le micro-rupteur, le même temps de réponse du système permet à la celle de s'écouler jusqu' au moment où le mabet-encelleur échappe de la planche. When the rear part of the board releases the microswitch, the same response time of the system allows that to flow until the mabet-encelleur escapes from the board.

selon une presiére variante de ce perfectionnement, le micro- rupteur est romplasé par une cellule photo-électrique. Dans le cas d'un changement de vitesse d'avancesent de la planche, un relai de temporise- tion électronique, réglable en fraction de seconde sur un cadrans est placé entre la cellule et la contacteur de commande du système électro-pneumatique. Cette disposition évite donc le déplacesent latéral de la cellule, laquelle peut être ainsi fixée définitivenont a une distance détreminée, on ament du bec encoller du sabot.  according to a first variant of this improvement, the microswitch is filled in with a photoelectric cell. In the case of a change in speed of advancement of the board, an electronic delay relay, adjustable in fraction of a second on a dial is placed between the cell and the control switch of the electro-pneumatic system. This arrangement therefore avoids the lateral displacement of the cell, which can thus be fixed definitively at a predetermined distance, we love to beak glue the shoe.

Selon un second perfectionnement apporté à l'invention principale le sabot encolleur est rendu mobile autour d'un axe perpendiculaire au déplacesent de la planche à encoller de façon à lui permettre d'étre placé à tout noient dans l'axe de celle-ci migré ses défauts éventuels en largeur. et en rectitude. Ce centrage est assuré grâce à un patin solidaire du sabot, placé sur le chant de la planche à encoller, ainsi qu'à un ressort appuyant sur l'autre chant de celle-ci, de façon à maintenir le patin toujours en contact avec la planche. According to a second improvement made to the main invention, the sizing shoe is made mobile around an axis perpendicular to the displacement of the board to be glued so as to allow it to be placed at any point in the axis of the migrated board. its possible defects in width. and straight. This centering is ensured by a pad integral with the shoe, placed on the edge of the glue board, as well as a spring pressing on the other edge thereof, so as to keep the pad always in contact with the board.

Le dispositif représenté sur les figures 1 ot 2 se compose essen- tiallement d'un axe support du dispositif 1, sur lequel peut tourner un nan- chon2. Le sabot d'encellage 3 peut également tourner autour d'un axe 8, solidaire du manchon 2. Il est maintenu dans l'axe de la planche i encoller 14, grce à une butée de centrage 7 et d'un ressort presseur de centrage 6. Le mélange collant arrivant au clapet électro-pneumatiquo 17 est distribué sur la planche par les conduits de colle 16 et le bec du sabot 9.Celui-ci peut être naintonu à une certaine distance de la planche gré au bras de riglage 4, solidaire du manchon 2 et à une vis d'appui 5 ; un ressort 19 main- tient le bran 4, par l'intermédiaire de la vis 5 sur un appai rixe 20. The device represented in FIGS. 1 and 2 essentially consists of a support axis of the device 1, on which a nanochon2 can rotate. The fixing shoe 3 can also rotate around an axis 8, integral with the sleeve 2. It is held in the axis of the board i glue 14, thanks to a centering stop 7 and a centering pressure spring 6. The sticky mixture arriving at the electro-pneumatic valve 17 is distributed on the board by the glue conduits 16 and the spout of the shoe 9. This can be naintonu at a certain distance from the board adjusted to the rigging arm 4, secured to the sleeve 2 and to a support screw 5; a spring 19 holds the strand 4, by means of the screw 5 on a fixture 20.

Conforxéxent à un perfectionnement du présent certificat d'addition, lorsque la planche à encoller 14 avance sous le sabot maintenu en bonne dis'- tance d'encollage par le bras 5, le ressort de centrage 6 a pour effet do tenir en contact permanent la butée 7 contre le flanc droit de la planche, ce qui maintient ce dernier dans l'axe de la planche, malgré les défauts on largeur ou en rectitude de eelle-ci.  Convenient to an improvement of this certificate of addition, when the glue board 14 advances under the shoe maintained in good gluing distance by the arm 5, the centering spring 6 has the effect of keeping in permanent contact the stop 7 against the right flank of the board, which keeps the latter in the axis of the board, despite the defects in width or in straightness thereof.

Selon un autre perfectionnement du présent certificat d'addition, le nicro-rupteur 10 est fixé sur une réglo graduée 11 à une certaine distan- ce du bec du sabot, de façon à ce que le temps mis par la planche 14 pour arriver en position 15 corresponde au temps de réponse du système. Le contact ayant été effectué en 10, la colle commancern v couler en 15,
la figure 3, selon une variante du présent perfectionnement, repr*- sente le remplacement du micro-rupteur 10 par une cellule photo-électrique 12, et d'un relai de temporisation électronique 13. Grâce à cet agencesent, il n'est plus nécessaire de déplacer la cellule 12 le long d'une règle gra- duée. En effet, celle-ci est fixée définitivement en position 12. Suivant 10 vitesse d'avancement de la planche, le temps de réponse du système est conplété par la temporisation électronique du reliai 13.
According to another improvement of this addition certificate, the micro-switch 10 is fixed on a graduated regulo 11 at a certain distance from the shoe spout, so that the time taken by the board 14 to arrive in position 15 corresponds to the system response time. The contact having been made in 10, the glue commancern v to flow in 15,
FIG. 3, according to a variant of the present improvement, shows * - the replacement of the micro-switch 10 by a photoelectric cell 12, and of an electronic time relay 13. Thanks to this agencies, it is no longer necessary to move cell 12 along a graded ruler. In fact, the latter is permanently fixed in position 12. Depending on the speed of advancement of the board, the response time of the system is completed by the electronic timing of the link 13.

Des applications particulièrement intéressantes peuvent être t l'encollage des poutres en lamellé collé ; les techniques de panmeantage, aboutage et panneaux contreplaqués et complexes.  Particularly interesting applications can be: gluing of glued laminated beams; panmeantage, butting and complex plywood panels.
