Definitions

  • the invention relates to a device for the automatic lateral alignment of logs, boards and the like on a reference plane of a sawing machine, to which the timbers are fed one after the other in the longitudinal direction and which has saws working parallel to this on both sides of the reference plane, the device having at least two in the conveying direction in Distance from each other pairs of transversely to the vertical directional reference plane to the wood can be equipped straightening elements, which are coupled in terms of movement so that they move symmetrically with respect to the directional reference plane and move away from them.
  • Such devices serve to ensure optimal wood utilization.
  • the object of the invention is to provide a device which takes better control of the woods and which is also suitable for short and long, thin and thick or narrow and wide, straight and crooked woods and those with increasing and decreasing in the conveying direction Align and feed taper in any order and at high conveying speed to the reference reference plane of the sawing machine.
  • the straightening elements are designed as drivable conveyor belts which are each pivotably mounted on brackets which can be moved independently of one another transversely to the conveying direction about an axis running parallel to the shafts of their deflecting rollers, the brackets of the conveyor belt pairs being coupled to one another such that they can only move symmetrically towards and away from the reference plane.
  • the term "conveyor belt” used for reasons of simplification is to be understood as an aggregate of a closed conveyor belt and a frame having, for example, a top and a bottom plate, in which the waves of the Deflection rollers are stored.
  • the conveyor belt can be formed by chains with a non-slip outer surface.
  • the conveyor belts can consist of two chains arranged one above the other and toothed carrier bars connecting them.
  • the conveyor belts can be pivoted by appropriate storage of the frames.
  • conveyor belts As a result of the pivotable mounting of the conveyor belts on the brackets moving symmetrically to the reference reference plane, the conveyor belts with the strands facing each other can lay against the wood over their entire length, so that there is a good grip. In addition, conveyor belts are more suitable for aligning crooked wood, which leads to optimal utilization.
  • the conveyor belts are preferably each pivotably mounted on two brackets which can be moved independently of one another and thereby cause the pivoting movement of the conveyor belts.
  • brackets which can be moved independently of one another and thereby cause the pivoting movement of the conveyor belts.
  • console links which are pivotally connected to them in the following, arranged in a vertical plane transversely to the directional reference, hereinafter referred to as console links, which at the other ends are pivotally attached to a base frame of the frame carrying the device are.
  • a bracket link of a pair is connected to a bracket link of the other, lying on the opposite side of the reference plane by a cross coupling rod and a linkage, which can be changed in length by means of a cylinder-piston unit.
  • brackets can also be arranged on rails that run transversely to the conveying direction and on which they can be moved.
  • the movement drive is also best carried out by console links, whereby only one is required for each console, which is about a fixed axis, e.g. on the frame carrying the device, is mounted, the links of the corresponding brackets of the conveyor belt pairs being connected in a known manner (see DE-OS 29 33 909) by a cross coupling rod and by a linkage, which is also by means of a cylinder-piston unit its length can be changed.
  • the bracket links are connected to the brackets via intermediate links that compensate for changes in length.
  • the cylinder-piston unit which is attached to a bracket link with its linkage, is supported on a pillar of the frame.
  • a cylinder-piston unit that is half shorter can be used.
  • the device is operated such that the distance between two successive woods is at least as long as the length of the conveyor belts of the conveyor belts, which is of the order of one meter.
  • bracket links of a conveyor belt one behind the other in the conveying direction, preferably at their ends pivotally connected to the base frame or frame, with rotary axes which are arranged on the bracket core in a rotationally fixed manner, with the two aligned axes of rotation have a coupling-like rotation limitation.
  • an additional adjustment drive is provided for the second pair of conveyor belts in the conveying sequence, which, after this pair of conveyor belts becomes free and its drive causing the attachment to the wood, e.g.
  • Such an adjustment of the second pair of conveyor belts is e.g. required if a thin wood is followed by a much thicker one, so that after the thinner wood has run out of the second pair of conveyor belts, this is set too narrowly for the incoming thicker wood.
  • the cylinder-piston assemblies which are arranged between the bracket core of the second conveyor belt pair, are depressurized, so that the conveyor belts of this pair can be moved freely, and the side links of the two conveyor belts on this side, provided with a multi-position cylinder-piston unit, are adjusted to the length of the other side links of the conveyor belts by acting on the cylinder-piston units, as a result the described arrangement of the side links in cooperation with the rail, an aligned position of the conveyor belts one behind the other regardless of which pivot position the conveyor belts of the first pair of conveyor belts occupy.
