Definitions

  • 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.
  • 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 bottom 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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, at its end corresponding to the position furthest from the free end of the arm relative to the tip, by a groove through which the projection can enter the interior of the tube, allowing the arm to '' be cleared on the side of the table to place the logs or treat particularly large ones.
  • 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.
  • the sliding tubes of the two arms are located on each side of the table.
  • the machine 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.
  • 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.
  • 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.
  • the frame 7 carries an assembly 13 supporting the drive motor of a rotary threaded cone 14 disposed above the work table whose horizontal axis of rotation is parallel to the sides 2 and 3.
  • a hollow tube of square section 15 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.
  • 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.
  • the arm 17 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.
  • the user grasps the arm 17 to the location of the vertical portion or the horizontal portion perpendicular to the axis of the cone.
  • the end 19 of the arm 17 is opposite and very close to the tip of the cone 14.
  • the end 19 may have a shape which widens towards the point.
  • the lumen 16 is extended downward.
  • the projection 18 is at the front end of the slot 16
  • 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.
  • the tube 15 can be fixed to the left of the table or even under the tray 5.
  • 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.
  • 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 this the latter can be replaced, for example, by a blind hole in the central part of the gantry which necessarily remains in alignment with the tip of the c8ne 14.
