Definitions

  • the invention relates to a cutting and splitting machine for cutting sawlog into individual pieces and splitting sawlog pieces into chopped wood, said machine comprising a feed table for feeding sawlog into the machine.
  • the cutting and splitting machine has a section for cutting sawlog into individual pieces and a section for splitting sawlog pieces into chopped wood.
  • the sections are normally arranged side by side.
  • Cutting and splitting machines with two different layouts for the cutting section and the splitting section are known from the prior art.
  • the sections are arranged side by side in a horizontal direction.
  • a circular saw cuts a piece of a sawlog to a predetermined length in the cutting section, a push hatch then rolls the cut sawlog piece into the splitting section where a splitting knife splits the sawlog piece into chopped wood.
  • the sections are arranged on top of each other in a vertical direction.
  • a circular saw cuts a piece of a sawlog to a predetermined length in the cutting section, a retaining hatch retracts to allow the cut sawlog piece to fall, under the force of gravity, into the splitting section where a splitting knife splits the sawlog piece into chopped wood.
  • the circular saw always moves perpendicularly to the sawlog.
  • the cutting and splitting machine is usually equipped with a feed table on which a piece of sawlog is conveyed, which is then conveyed to the cutting and splitting machine via a conveying means in the form of conveyor rollers, a rubber belt or a chain conveyor with which the feed table is equipped, to be cut.
  • the feed table is usually equipped on one of the longitudinal sides with side stops in the form of a wall or restraining rollers, which prevent a piece of sawlog from falling off the feed table and at the same time guide it into the cutting and splitting machine.
  • the feed table may be tilted slightly in the direction of said stops.
  • the feed table is usually connected to the frame of the cutting and splitting machine via hinges so that it can be swiveled upwards from a horizontal to a vertical position, making the cutting and splitting machine easier to transport and taking up less space when not in use.
  • the technical problem is how to configure a cutting and splitting machine having a feed table that will allow the sawlog jam on the feed table to be eliminated without the operator having to physically interfere with the cutting and splitting machine.
  • the advantage of the cutting and splitting machine according to the invention is that the operator of the machine does not have to physically intervene on the feed table to move individual pieces of sawlogs when sawlogs are jammed on the feed table.
  • the conveying means does not stop, so as soon as a piece of sawlog comes into contact with it again, the piece is immediately conveyed forward into the splitting machine.
  • a further, and not negligible, advantage is that this reduces the possibility of injury to the operator, as the operator does not have to reach between individual pieces of the sawlogs.
  • the cutting and splitting machine 1 comprises:
  • the feed table 5 comprises driven conveying means, which may be formed as a conveyor belt, a conveyor chain or conveying toothed rollers 8, as in the embodiment on Fig. 1 , for conveying the pieces of sawlogs to be fed into the interior of the cutting and splitting machine for cutting and splitting.
  • the feed table 5 comprises at least two toothed rollers, preferably more than two, one conveying toothed roller 8 being coaxially arranged in the hinge 7.
  • the feed table 5 is usually equipped on one of the longitudinal sides with side stops 9 in the form of a wall or restraining rollers, which prevent a piece of sawlog from falling off the feed table and at the same time guide it into the splitting machine.
  • the feed table 5 may be tilted slightly in the direction of said stops 9.
  • the cutting and splitting machine 1 further comprises a hydraulic cylinder 6, which is hinged at its one end 61 by means of a fixing eye 63 in a hinge 10 on the machine housing 2 and at its second end 62 by means of a fixing eye 63' hinged to the outer part 52 of the feed table in a hinge 11, such that the outer part 52 of the feed table swivels up or down with respect to the longitudinal axis of the feed table 5 as a result of the action of the hydraulic cylinder 6.
  • the outer part 52 of the feed table swivels up or down relative to the longitudinal axis of the feed table 5 by an angle ⁇ of less than ⁇ 45°, preferably less than ⁇ 30°, due to the action of the hydraulic cylinder 6.
  • the hinge 11 is arranged on the underside of the outer part 52 of the feed table, i.e. on the side facing the ground during operation of the machine, however, the hinge 11 may also be arranged elsewhere on the outer part 52 of the feed table.
  • the hydraulic cylinder 6 is in fluid communication with the hydraulic valve, which is part of the hydraulic system of the machine.
  • the hydraulic valve is manually controlled by the machine operator via a control lever that is part of the control panel.
  • the operator determines that a sawlog piece is not being conveyed forward towards the machine, he/she swivels the feed table up or down by means of the hydraulic cylinder 6 by an angle ⁇ such that the sawlog piece, due to the inclination of the feed table 5, is brought back into contact with the conveying toothed rollers 8, which move it forward.
  • the size of the swivel angle ⁇ depends on the unevenness of the sawlog piece.
  • the conveying toothed rollers 8 do not need to be stopped but are only continuously driven and rotated so that as soon as a piece of sawlog comes into contact with them again, they grip it and convey it further into the splitting machine.
