Definitions

  • the invention relates to a device for cutting round logs by means of a circular saw arranged in a cross conveyor, the cross conveyor having a plurality of conveyor chains running side by side and equipped with carriers.
  • the log is sawn into log sections during continuous or intermittent passage past the circular saw.
  • the drivers attached to the conveyor chains guide the log against the rotating circular saw, the direction of rotation of which is selected so that the log is pressed down by the engagement of the circular saw onto the conveyor chains and thereby held while it is being moved by the conveyor chains against the circular saw and is sawed up.
  • the cut surface of the log moves along the circular saw blade.
  • the direction of the circumferential movement of the circular saw is directed from bottom to top. If the cut surface of the log in this area comes into contact with the circular saw teeth, the sawn-off log is thrown up, which can lead to accidents, damage to the machine or damage to the log. Hold-downs that hold the log in the area of the exit from the circular saw's flight circle would impair the conveyance of the log, especially since the hold-downs would have to adapt to the changing thickness of the log. Another difficulty is that relatively high and shock-like loads can occur if the log after the initial contact in the exit area of the circular saw is lifted and tilted and jammed.
  • the object of the invention is therefore to design a device of the type mentioned with the least possible design effort so that contact between the cutting surface of the log and the circular saw in the region of the exit from the flight circle of the circular saw is reliably prevented.
  • conveyor chains run at an acute angle to the cutting plane of the circular saw that the conveyor chains arranged on one side of the cutting plane, seen in the conveying direction, run diverging from the conveyor chains arranged on the other side of the cutting plane.
  • the log sections lying on the conveyor chains move away from the circular saw blade on both sides.
  • the cut surfaces of the log are on both sides at a distance from the circular saw blade, so that renewed, undesired contact with the saw teeth is reliably prevented.
  • Hold-down devices or other additional devices can be completely dispensed with.
  • link chains used for such transverse conveyors can be designed with so much lateral play without impairing their function that they run obliquely onto the associated chain wheels at the acute angle provided according to the invention or can run off them. It is thus possible, as was previously the case with cross conveyor systems, to arrange only a single chain shaft at the end of the feed and at the end of discharge, which run parallel to one another.
  • the skewing of the conveyor chains desired according to the invention is achieved solely by changing the spacing of the chain wheels.
  • the conveyor chains on one side of the cutting plane run perpendicular to the shafts as usual, that the conveyor chains on the other side of the cutting plane run obliquely to the shafts, and that the cutting plane of the circular saw between them approximates in the bisector. This ensures that only the conveyor chains lying on one side of the cutting plane run obliquely onto the sprockets or run from them.
  • the inclination between the other conveyor chains and the circular saw is achieved by inclining the circular saw.
  • the illustrated cross conveyor 1 has two groups of endless revolving conveyor chains 2 and 3, only two conveyor chains 2 and 3 of each group being shown in FIG. 2.
  • the conveyor chains 2, 3 run at the feed end of the cross conveyor 1 via chain wheels 4 or 5, which sit on a common shaft 6.
  • a shaft 7 is arranged parallel to the shaft 6 at the discharge end and carries chain wheels 8, 9, over which the conveyor chains 2 and 3 run. One of the two shafts 6, 7 is driven.
  • the conveyor chains 2, 3 are equipped at regular intervals with drivers 10, each of which receives a round timber 12 from a roller conveyor track 11 at the end of the feed and in the direction indicated by an arrow 13 against a circular saw 14, which between the two groups of conveyor chains 2 and 3 is arranged.
  • a drive motor 15 is indicated in FIG. 2, which drives the circular saw 14 via a belt drive 16.
  • Fig. 1 it is shown that the bearing of the circular saw 14 can be attached to a swivel arm 18 which can be raised by means of a pressure-actuated cylinder 17.
  • the circular saw 14 divides the round wood 12 into round wood sections 12 ′ and 12 ′′, which are thrown onto an inclined surface 19 at the discharge end of the cross conveyor 1 and are transferred by means of a pivotable transfer device 20 to a longitudinal conveyor 21 which conveys the round wood sections 12 ′, 12 ′′.
  • the conveyor chains 2 of the group arranged on one side of the cutting plane of the circular saw 14 are arranged parallel to one another and perpendicular to the axes of the shafts 6, 7.
  • the conveyor chains 3 of the other group run at an obtuse angle slightly deviating from the right angle to the axes of the shafts 6 and 7, d. H. the conveyor chains 3 run obliquely onto the associated sprockets 5 and 9 and from them.
  • the circular saw 14 determining the cutting plane lies approximately on a bisector between the two groups of conveyor chains 2 and 3, respectively.
  • the inclination of the groups of conveyor chains 2 and 3 to each other is easily achieved in that the distance between the sprockets 9 to the sprockets 8 at the discharge end of the cross conveyor 1 is greater than the corresponding distance of the sprockets 5 from the sprockets 4 at the feed end.
