  • wood planing is to level one of the surfaces rough sawing of a piece of wood, that is to say, planing it. It's the first working phase.
  • the slotting operation consists of forming a mortise in a piece of wood, a mortise being a hole of generally rectangular section, this hole being intended to receive the post of another assembled part.
  • the machine tool includes a support table consisting of two surfaces between which a planing cylinder rotates arranged transversely.
  • the two table surfaces are offset by a height determining the thickness of the chip.
  • the cylinder of planing includes a cylindrical tool holder on which are secured, following its generators, cutting blades.
  • Planing is carried out by moving the part to be planed resting on the support table, the part being moved perpendicularly to the planing cylinder driven in rotation.
  • This hood generally includes a gutter movable between a protective position pressed against the planing cylinder along the entire length of it, thus preventing access to the planing cylinder, and a position of use of the jointer allowing at least one access partial to the planing cylinder, the gutter being spaced from it or in a position of only partial covering of the planing cylinder.
  • the mortiser generally has a suitable rotary mandrel to receive bits allowing the drilling of successive holes in a piece of wood.
  • a rotational drive of the cylinder and the mandrel by the same geared motor group it is known that the mandrel and the planing cylinder are coupled in rotation.
  • fix the mandrel axially at the end of the planing cylinder it is known to fix the mandrel axially at the end of the planing cylinder.
  • the object of the invention is to propose a solution to this risk problem injury to the user by a slotting bit left in place when using the jointer.
  • the invention relates to a machine tool for working the wood of the aforementioned type, characterized in that it comprises a movable flap movable relative to the axis of the mandrel along a retraction path, between at least one active obstruction position, in which the flap extends in the axial extension of the mandrel and a retracted position, wherein the flap is away from the axial extension of the mandrel, and in that the flap and said cover are adapted to cooperate in order to allow the flap to be in its retracted position only when the movable cover is in its protective position and in order to maintain the protective cover in its protective position as long as the flap is in its position retracted.
  • the machine tool shown in Figure 1 is intended for the work of wood. It incorporates a jointer 12 and a mortiser 14.
  • the machine comprises a frame 16 supporting a horizontal table 18 of the jointer.
  • Table 18 has two horizontal flat surfaces 20A, 20B whose height offset is adjustable. The height between the front surface 20A and rear surface 20B is equal to the thickness of the chip to be removed from the piece of wood applied to the table 18.
  • a planer rotary cylinder 22 Between the two surfaces 20A and 20B is disposed transversely a planer rotary cylinder 22.
  • This cylinder shown in Figure 2, has a cylindrical tool holder on which are fixed sharp blades extending along tool holder generators.
  • the planing cylinder 22 is rotated around its axis X-X by a gearmotor group not shown.
  • the part of the planing cylinder 22 exposed between the surfaces 20A and 20B is protected by a movable protective cover 24.
  • the cover protection 24 includes an arm 26 articulated at one end 28 relative to table 18.
  • the arm 26 is articulated around an axis Y-Y extending parallel to the axis X-X of rotation of the cylinder 22.
  • the cover 24 comprises a cover gutter 30 generally matching the shape of the cylinder. This gutter generally extends above of the exposed part of the cylinder 22. It is movably mounted to slide along the axis X-X of the cylinder in a slide 32 brought to the free end of the arm 26.
  • An adjustment screw 34 is mounted on the arm 26. It cooperates with the table 18 in order to adjust the angular offset between the surface of table 18 and the arm 26. In addition, elastic return means of the arm 26 away from the table 18 are interposed between the arm and the table.
  • the cover gutter 30 is movable between a position of total coverage of the planing cylinder 22 and at least one position partial coverage of the planing cylinder 22.
  • roof gutter 30 is shown in its total coverage position.
  • the gutter 24 is moved in translation in the direction of the arrow F1 relative to backstage 32.
  • the entire protective cover 24 can be moved by relative to the table 18 by angular movement of the arm 26 between a position active protection preventing access to the planing cylinder, the gutter being in full cover position, and a use position of the planing cylinder.
  • the gutter 30 completely covers the planing cylinder and this is applied against the table 18, the arm 26 being completely folded against the table 18.
  • either the gutter 30 is brought into a partial protective position, as explained above, either the arm 26 is angularly offset by the table 18, so that the gutter 30, even if it extends along any its length above the planing cylinder 22, is spaced of it by an interval allowing the passage of a piece of wood to be planed.
  • the mortiser 14 fitted to the machine tool 10 comprises a mandrel 50 axially fixed at the end of the planing cylinder 22, at the end thereof located on the side of the arm 26.
  • the mandrel 50 is integral in rotation with the cylinder 22. It is suitable to receive a drill bit intended for drilling successive holes in a piece of wood for making a mortise.
  • the mandrel 50 is disposed inside a tubular protective casing 52 having an opening 54 located in the axial extension of the mandrel. This opening 54 allows the passage of a wick whose end attachment is secured to the mandrel and the active end of which protrudes out of the housing 52.
  • a shutter 56 for closing the opening 54 is articulated about an axis Z-Z relative to the housing 52.
  • the axis Z-Z extends parallel to the X-X axis of the mandrel.
  • the flap 56 has a general shape of a disc. It is articulated in an eccentric point located in the upper half of the housing 14 facing the free end of the arm 26.
  • the flap 56 is adapted to be movable between a position obstruction of the opening 54 as illustrated in FIGS. 1 and 2 and a retracted position illustrated in Figure 3, in which the flap is out of the way of the axial extension of the mandrel and allows the passage of a drill bit across opening 54.
  • the flap 56 In order to completely free the opening 54, the flap 56 has a clearance 58 provided at its periphery.
  • the flap 56 has a notch 60 adapted for the passage of a pin 62 during the raising of the flap towards its retracted position while the protective cover 24 is in its protection position of the planing cylinder.
  • the notch 60 has at its end a receiving notch 64 of pawn 62.
  • the pin 62 is secured to the free end of the arm 26 and more precisely to the slide 32.
  • the pin 62 extends in the direction of the mandrel 50. It projects slightly beyond the end of the roof gutter 30 when the latter is in its position of total cover of the cylinder planing 22.
  • the pin 62 has a groove 66 extending in the plane of movement of the flap 56.
  • the section of diameter reduced by the groove 66 of the pawn is adapted to be received in the notch 60 of the flap when the latter is brought to its retracted position.
  • the flap 56 is normally in its position of obstruction of the opening 54, prohibiting the establishment a bit in the mandrel 50. Indeed, the flap 56 is maintained in this position in a stable equilibrium state under the action of its own weight.
  • the arm 26 is free to be moved angularly to allow the spacing of the roof gutter 30 by compared to table 18 in order to ensure the passage of a piece to be planed above of the cylinder 22.
  • the gutter 30 is free to be moved in translation relative to arm 26 in order to expose at least part end of the planing cylinder 22.
  • the end 36 of the gutter which projects beyond of the pin 62 extends through the path of movement of the flap 56.
  • the edge of the gutter 30 thus forms a stop preventing angular displacement of the shutter and thus immobilizing it in a position obstructing the extension axial of the mandrel.
  • the arm 26 is then raised so that the distance between the point of articulation of the flap 56 and the entry of the notch 60 is less than the distance separating the point of articulation of the flap of pawn 62. Pawn 62 cannot then penetrate into the notch 60 and this constitutes a stop in which strikes flap 56 during an attempt to move it towards its retracted position.
  • the flap 56 can be brought into its retracted position, the gutter 30 not annoying plus its displacement and the pin 62, correctly positioned in relation to the axis of articulation of the flap, which can be received in the notch 60.
  • the clearance 58 is located opposite the opening 54.
  • the pin 62 is then received in the notch 64.
  • a drill bit M can then be placed in the mandrel and the mortiser can be used.
  • the gutter 30 cannot be moved in translation to expose part of the planing cylinder, the flap 56 being arranged immediately opposite the end of the gutter 30.
  • wick M constitutes a stop preventing tipping section 56.
  • the mortiser cannot be used only when the protective cover 24 is in its active position of protection. Conversely, the jointer can only be used in the absence drill bit in the mortiser chuck.
