Abstract

The device comprises a round plate (2) supported by two guides (3) and has a spring (4). The device also has two buffers (5). When the operator acts on a pedal, the machine moves and comes into contact with the part to be machined, the saw cover makes its cut and compresses the spring (4). At the end of cutting, the machine moves back, it is then that the spring eases and the plate (2) rises again from the cut part. USE/ADVANTAGE - In sawing devices. Allows the rapid ejection of the cutting effected by a sawing device.

Description

La présente invention concerne un dispositif d'éjection de la partie tronçonnée d'un panneau,en l'occurence, panneau de meuble. The present invention relates to a device for ejecting the sectioned part of a panel, in this case, a furniture panel.

Le défonçage de ce panneau est traditionnellement effectué par un foret à lames et demande une grande Puissance ainsi qu'une perte de temps.En cas de Puissance trop faible, le relais thermique du moteur se aet en action,arrête le moteur qui chauffe, et provoque un arrêt de travail. The routing of this panel is traditionally carried out by a blade drill and requires a great Power as well as a loss of time.In case of Power too low, the thermal relay of the motor is activated and stops the motor which heats up, and causes a work stoppage.

Le défonçage avec la scie cloche traditionnelle pose le problème du disque découpé,qui lui, demeure dans la cloche de la dite scie. Routing with the traditional hole saw poses the problem of the cut disc, which remains in the bell of the said saw.

A ce point, intervient le dispositif d'éjection de la partie découpée qui, lorsque la machine se déga6e, après avoir effectué son entaille,renvoie le disque découpé du panneau. At this point, the device for ejecting the cut part intervenes which, when the machine is dega6e, after having made its notch, returns the cut disc from the panel.

Ce,ou ces disques,éjectés,un ou des panneaux nouveaux sont présentés à la machine pour une nouvelle opération,la main humaine n'ayant plus à intervenir pour dégager les disques. Il en résulte aussi une diminution des risques d'accidents du travail. This or these discs, ejected, one or more new panels are presented to the machine for a new operation, the human hand no longer having to intervene to release the discs. It also results in a reduction in the risk of accidents at work.

Ce dispositif peut être prévu sur tous les diamètres,sans distinctio de matières. This device can be provided on all diameters, without differentiating between materials.

La Figure 1 représente en coupe la scie cloche et son dispositif. Figure 1 shows in section the hole saw and its device.

La Figure 2 représente en coupe une variante du plateau d'éjection muni da QUATRE galets réduisant le frottement sur la partie à découper. Figure 2 shows in section a variant of the ejection plate fitted with FOUR rollers reducing friction on the part to be cut.

Le dispositif représenté sur la figure 1 comporte une vue en coupé de la scie(1),en(2)le poussoir de découpes soutenu par ses guides(3); en (4)le ressort qui se trouve comprimé lors de la découpe sedétend et éjecte les déchets dès que la machine se dégage.En(5)écrous des guides. The device shown in Figure 1 includes a sectional view of the saw (1), in (2) the cutout pusher supported by its guides (3); in (4) the spring which is compressed during cutting relaxes and ejects the waste as soon as the machine is released. In (5) nuts of the guides.

Pour être efficace, le parcours de ce dispositif,doitêtre maxi à l'intérieur afin de permettre la plus grande profondeur de découpe,et en détente, arriver au niveau même des extrèmités avancées des dents de la scie.  To be effective, the path of this device must be maximum inside to allow the greatest depth of cut, and in relaxation, arrive at the very level of the advanced ends of the saw teeth.

Une variante tenant compte da la friction du plateau (2)sur la découpe, comporte, incorporé dans ce plateau(2# quatre galets coniques(7 disposés dtaxe en axe à 900 ayant pour but d'éliminer l'incidence de cette friction sur la partie à découper. A variant taking account of the friction of the plate (2) on the cutout, comprises, incorporated in this plate (2 # four conical rollers (7 arranged with axis in axis at 900 having the aim of eliminating the incidence of this friction on the part to be cut.

Le ressort utilisé est de type conique", celui-ci exigeant en effet un encombrement inférieur quand il se trouve comprimé. The spring used is of the conical type ", this in fact requiring a smaller size when it is compressed.

Le ressort (4)est incorporé à l'intérieur de la cloche et emprisonné entre les guides (3) et la collerette (6) de fixation de l'entrainement.Les guides (3) sont limités dans leur course chacun par un butoir constitué par un écrou (5), supportant ainsi le ressort (4). The spring (4) is incorporated inside the bell and trapped between the guides (3) and the flange (6) for fixing the drive. The guides (3) are limited in their travel each by a stopper made up by a nut (5), thus supporting the spring (4).
