Description

DISPOSITIF ASPIRATEUR DE POUSSIFRES
L'invention concerne un dispositif aspirateur de poussières incluant un moyen dynamique de transfert des poussières et un moyen aspirateur de poussières généré par ledit moyen dynamique.DUST VACUUM DEVICE
The invention relates to a dust suction device including a dynamic dust transfer means and a dust suction means generated by said dynamic means.

L'invention concerne plus particulièrement un tel dispositif aspirateur appliqué à une scie et qui, lorsqu'il est utilisé, empêche l'encrassement de la table de travail de la scie.The invention relates more particularly to such a vacuum device applied to a saw and which, when used, prevents fouling of the work table of the saw.

L'invention peut être appliquée par exemple aux scies à disques ou aux scies à ruban dont la lame se déplace au travers d'une fente d'une table de travail.The invention can be applied for example to disc saws or band saws whose blade moves through a slot in a work table.

Un dispositif connu aspirateur de poussières utilise une buse d'aspiration disposée à proximité de la table de travail. Une telle buse ne peut empêcher l'agglomération des poussières notamment lorsque la scie travaille dans une atmosphère humide ou lorsque la lame de la scie doit être refroidie par un fluide.A known device for vacuuming dust uses a suction nozzle disposed near the work table. Such a nozzle can not prevent agglomeration of dust especially when the saw works in a humid atmosphere or when the saw blade must be cooled by a fluid.

On a ainsi pu constater un certain nombre d'inconvénients plus ou moins dommageables pour la scie ou pour l'opérateur, notamment : - I'encrassement du carter de la scie par accumulation de sciure tombée par
gravité et non évacuée.We have thus been able to observe a certain number of disadvantages which are more or less damaging to the saw or to the operator, in particular: - fouling of the saw casing by accumulation of sawdust fallen by
gravity and not evacuated.

- I'encrassement des galets d'appui de la lame de coupe entraînant leur
blocage.- fouling of the support rollers of the cutting blade causing their
blocking.

- I'encrassement de la lame de coupe qui véhicule ainsi des sciures tout au
long de son parcours.- fouling of the cutting blade, which carries sawdust all the way
along its course.

- Des retombées de sciure véhiculées par la lame sur la table de travail et
sur l'opérateur, obligeant le port d'un masque respiratoire. - Fallout from sawdust carried by the blade on the work table and
on the operator, requiring the wearing of a respiratory mask.

Ces inconvénients sont renforcés dans le cas de sciage de matériaux (à forte densité) comme les blocs de résines polymères utilisés dans la fabrication d'outillages prototypes de presses.These drawbacks are reinforced in the case of sawing materials (at high density) such as blocks of polymer resins used in the manufacture of prototype press tools.

L'invention a pour objet un perfectionnement apporté aux dispositifs aspirateurs de poussières qui remédie à l'inconvénient des dispositifs connus.The subject of the invention is an improvement made to dust suction devices which overcomes the drawback of known devices.

L'invention a encore pour objet un dispositif aspirateur de poussières de conception modulaire dont l'agencement augmente la sécurité d'emploi de la scie.The subject of the invention is also a dust suction device of modular design, the arrangement of which increases the safety of use of the saw.

Selon l'invention le moyen dynamique de transfert des poussières est animé sous le plateau de travail par une pression de soufflage localisée devant et à proximité de la lame de scie tandisque le moyen aspirateur localisé derrière et à proximité de ladite lame est raccordé à un système évacuateur et de stockage des poussières.According to the invention, the dynamic dust transfer means is animated under the work plate by a blowing pressure located in front of and near the saw blade while the vacuum means located behind and near said blade is connected to a system. dust evacuator and storage.

Le dispositif ainsi réalisé autorise le soufflage par dérivation du circuit d'air comprimé de l'atelier de sciage. Avantageusement le soufflage est réalisé selon une faible section qui permet l'obtention d'une forte pression localisée sur la lame de coupe avec une efficacité optimale. Le soufflage est ainsi réalisé face aux dents de la scie, tandisque l'aspiration est réalisée face au soufflage. L'aspiration peut-être réalisée par un aspirateur industriel extérieur à la scie, ou par le dispositif d'aspiration existant.The device thus produced authorizes blowing bypassing the compressed air circuit of the sawmill. Advantageously, the blowing is carried out in a small section which allows obtaining a high localized pressure on the cutting blade with optimal efficiency. The blowing is thus carried out facing the teeth of the saw, while the suction is carried out facing the blowing. The suction can be carried out by an industrial vacuum cleaner external to the saw, or by the existing suction device.

Le dispositif combiné d'aspiration et de soufflage peut etre asservi à la mise en marche de la scie et ne réclame pas l'intervention de l'opérateur.The combined suction and blowing device can be controlled by switching on the saw and does not require operator intervention.

La solution proposée permet également de laisser la lame, les galets d'appui et le carter de la scie exempts de sciure.The proposed solution also makes it possible to leave the blade, the support rollers and the saw casing free of sawdust.

La solution proposée permet en outre de travailler sans masque respiratoire dans une atmosphère non polluée. The proposed solution also makes it possible to work without a respiratory mask in an unpolluted atmosphere.

La solution proposée reste efficace quelle que soit la nature du matériau scié et s'adapte à toute inclinaison de la table de travail.The proposed solution remains effective whatever the nature of the sawn material and adapts to any inclination of the work table.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'un exemple de réalisation des dispositifs en référence au dessin annexé dans lequel; - la figure 1 est une vue en perspective qui montre une partie d'une scie à
ruban, à laquelle est appliqué le dispositif conforme à l'invention.Other characteristics and advantages of the invention will appear on reading the description of an exemplary embodiment of the devices with reference to the appended drawing in which; - Figure 1 is a perspective view which shows part of a saw
tape, to which the device according to the invention is applied.

- la figure 2 est une représentation schématique du circuit pneumatique de
commande.- Figure 2 is a schematic representation of the pneumatic circuit of
ordered.

La figure 1 représente schématiquement une table de travail 10 et une lame de scie 1 1 qui passe à travers une fente 12 de la table 10. La face inférieure de la table 10 supporte un étrier de fixation 13 constitué par une barrette 14 maintenue par des tirants 15, 15' vissés sur la table 10.Figure 1 schematically shows a work table 10 and a saw blade 1 1 which passes through a slot 12 of the table 10. The underside of the table 10 supports a fixing bracket 13 constituted by a bar 14 held by tie rods 15, 15 'screwed onto the table 10.

L'étrier de fixation 13 supporte le moyen dynamique de transfert des poussières de sciage décrit ci-après.The fixing bracket 13 supports the dynamic means for transferring saw dust described below.

Une douille tubulaire de raccordement 16 possède un orifice d'entrée 16e branché sur un raccord 17 du canal de pression 18 alimenté à partir d'un compresseur 20 au travers d'un détendeur 21 piloté par une électrovanne 22.A tubular connection sleeve 16 has an inlet orifice 16e connected to a connector 17 of the pressure channel 18 supplied from a compressor 20 through a pressure reducer 21 controlled by a solenoid valve 22.

L'orifice 16s débouche dans un canal d'évacuation 23 dans lequel est inséré un filtre purgeur 24 susceptible de permettre l'évacuation des poussières d'usinage telles que la sciure.The orifice 16s opens into a discharge channel 23 into which is inserted a drain filter 24 capable of allowing the evacuation of machining dust such as sawdust.

Plus particulièrement la douille de raccordement 16 est réalisée sous la forme d'un tube dont l'extrémité tournée vers l'orifice d'entrée 16e porte une fente de passage 26 de la lame 11. A proximité de la fente 26 est localisé un perçage de réception d'une vis d'immobilisation 27 du raccord 17 au canal de pression 18. More particularly, the connection sleeve 16 is produced in the form of a tube, the end of which faces the inlet orifice 16e carries a passage slot 26 of the blade 11. A hole is located near the slot 26 receiving a locking screw 27 from the connector 17 to the pressure channel 18.

L'électrovanne 22 montée sur le détendeur 21 est avantageusement reliée au circuit électrique de la scie et permet l'asservissement du soufflage à la mise en marche de la scie. Par ailleurs un manomètre 28 est raccordé au détendeur 21 et permet un réglage de la pression de soufflage. Une pression trop importante peut en effet entraîneur une vibration transversale de la lame de coupe. Un bon fonctionnement peut être constaté avec des pressions comprises entre 0.3 et I bar.The solenoid valve 22 mounted on the pressure reducer 21 is advantageously connected to the electric circuit of the saw and allows the control of the blowing when the saw is started. Furthermore, a pressure gauge 28 is connected to the pressure reducer 21 and allows adjustment of the blowing pressure. Too much pressure can indeed cause transverse vibration of the cutting blade. A good functioning can be noted with pressures ranging between 0.3 and I bar.

Le moyen aspirateur 30 entraîné par le moteur du compresseur 20 est localisé en aval de la lame 11. A cet effet le canal d'évacuation 23 est branché directement sur rorifice 16s de la douille 16.The suction means 30 driven by the compressor motor 20 are located downstream of the blade 11. For this purpose the discharge channel 23 is connected directly to the orifice 16s of the socket 16.

Le dispositif ainsi réalisé présente ainsi l'avantage de pouvoir être rapidement dissocié de la scie et peut etre prêt au montage sur une scie existante. The device thus produced thus has the advantage of being able to be quickly dissociated from the saw and can be ready for mounting on an existing saw.
