    The invention relates to a method and apparatus for feeding lumber, especially in connection with a four-band saw for separating and feeding side boards. The problem in four-band sawing is how to separate the boards of a pair of side boards sawed off from the sides of a log or block for further processing such as trimming. This problem is solved so that the side boards that are sawed off from the log are dropped by opening side guards and then directed the side boards by means of adjustable dropping flaps onto a transverse conveyor so that they remain on the conveyor with the cant edge focus up. The boards are then piled on top of each other and/or in a laminating fashion. The side boards are arranged, by shifting them against transient stops of the transverse conveyor, into a pile wherefrom the side boards can be suitably fed further by means of stopping members arranged in connection with the conveyor on a sloping plane. The stopping members can be adjusted into at least two different positions. In the first position the uppermost board of the pile of boards continues its movement but the rest are stopped. In the second position the next side board is released, and the rest are held back. This continues until all the boards are fed.

    The transport of the rifle from the four-saw machine (not shown) to the power plant is carried out by the conveyor 2 driven, for example, by an electric motor with a gearbox 17 and a chain transmission with an asterisk 18.
    One or several pairs of side stops I are installed at corresponding intervals by symmetrically several Bbigie conveyor 2 for a log or a log on either side of it. The side stops are mounted on the frame 19 with the possibility of movement by means of the axles 20 and are connected to each other by means of a rod 21, to the other end of which the piston of the hydraulic power cylinder 22 is attached.
    Dumpers 3 are made in the form of shaft-like elements fixed on a common axis 23 at respective distances one from the other — for example, at intervals of 50 cm from each other. The slope of the release flaps 45 can be adjusted by means of a hydraulic ram 24. These cylinders are located at either end of the rammers 3, out of space, ipo is required for conveyors 50 4 and 5.

    Conveyors 4 and 5 through inclined slopes 6 are connected to conveyors 38 that are at a lower level and equipped with transition stoppers 39 and 40. On the bow descent b is formed, for example, steel rods 41 attached at certain intervals to frame 25 and covered with steel plates 42. Below the steel plate, the support 43 is installed, with each of which with corresponding gearing is connected to the axis 44 of the stopper 7.
    . The stoppers 7 are made in the form of Krk or bent elements 45 attached to axis 44 on | Asstch 11II 1 n dr From a friend. With the stopper 7 located near the end of the axis 44, the piston of the hydraulic power lindra 46, KOTO1SH1Y itself is attached to the frame. By means of hydraulic mooring afooKKpa, it is possible to adjust the position of the stopper 7 relative to the bottom 6 descent from A to. It is preferable that the stoppers have one or several intermediate hollows to separate the boards. In sa
    For example, it is fastened to the frame of conveyors 4 and 5, and the frame is attached to the pull-out box 3.55.
    The cross conveyors 4 and 5 are chain or belt conveyors mounted on
    frame 25 below conveyor 2. Transporters. 4. and 5 are driven by an electric motor with a gearbox 26.27 and utenH with an asterisk 28, 29. The end wheels of the conveyors 4 and 5 interlock with one and the same axis 30 so that each conveyor can be driven as forward so back.
    With the conveyors 4 and 5, the transition stoppers 3 - 33 are combined. These stoppers, for example the stopper 31, are made of suitably bent rods 34 attached to
    conveyor 4. The rods 34 are located across the conveyor 5 at intervals, for example, 1.m. An auxiliary rod 36 is attached to the end of the axis 35, with which the piston of the hydraulic power cylinder 37 is connected.

    ° 5, which engages below

    Conveyors 4 and 5 are connected by inclined descents 6 to conveyors 38 that are at a lower level and equipped with transition stoppers 39 and 40. Oblique descent b is formed, for example, by steel rods 41 attached at certain intervals to frame 25 and covered with steel plate 42. Supports 43 are installed below the steel plate, with each of which with the corresponding gearing is connected to the axis 44 of the stopper 7.
    . The stoppers 7 are made in the form of krkzhov or bent elements 45 welded to the axis 44 on | Asstch 11ii 1 n each other. With the stopper 7, located near the end of the axis 44, the piston of the hydraulic power cylinder 46 is connected, KOTO1L1Y itself is attached to the frame. By means of a hydraulic footer afooKKpa, it is possible to adjust the position of the stopper 7 relative to the inclined descent 6 going from A to B. Preferably, the stoppers have one or more intermediate positions to separate the boards. In the very
    the lower position of the stoppers are completely under the inclined descent 6.
    The device works as follows.
    By means of a conveyor belt 2 cr 47, together with its side boards, are transported from the sawing station to the feeding station. Due to the action of the hydraulic ram 22, the side plates 48 and 49 are pressed against the rail 47 by means of the side stops 1 until the conveyor 2 transfers the sawn log to the position near the dumpers
    3 and the transverse conveyors 4 and 5. The side stops 1 are opened, and the dumpers 3, the inclination of which is adjusted accordingly, pass the side boards 48 and 49 onto the transverse conveyors 4 and 5.
    When the boards 48 and 49 fall, they collide with the transitional stoppers 31 of the transverse conveyors 4 and 5 (Fig. 3) and, therefore, are limited. The hydraulic power cylinder 37 begins to work, the stoppers 31 are rotated to the sides, and the conveyors 4 and 5 transport the boards all the way with the next stoppers 32. Due to the strength of the impact of the board, which in the phase lay in the transverse direction with layers of the same 50 and 51 in Figures 1 and 2) are stacked one on top of the other.
    The side stops (fig. 3) are opened while the drop arms 3 are lowered to their lowest position, and the boards 48 and 49 are directed onto the cross conveyors.
    4 and 5 edge up.
    If only one board on each side is sawed off from a log or log, or if it is necessary to direct the entire lumber to one side of the line, either the conveyor 4 or the conveyor 5 can be moved in the opposite direction so that the stoppers 52 control the feed of the boards or on the conveyor 4, or on the conveyor 5.
    Figure 4 shows the moment when the boards 53 and 54 arrived at the transient stops 33 of the transverse conveyor 5, the board 55 stopped at the stoppers 7 located on the inclined descent 6, and the board 56 continued to move until it stops at the stop 39 of the conveyor 38 located more low level. Now the stopper 39 rotates to the side and thus allows the board 56 to move up to the stopper 40, and the stopper 39 rises, and the stopper 7 allows the board 55 to pass to the stopper 39. After that, the stopper 7 rises due to the action of the hydraulic power cylinder 46. When the stopper 39 releases the board 53 and rises upwards, the stopper 33 is lowered and the boards 53 and 54 are released from the conveyor 5 for movement for the purpose of separation. The feeding method continues in a similar manner.
    In the case of replacement of the inclined descent 6 on the adjustable plane 8, the inclination of the plane and, consequently, the depth of the pocket can be adjusted depending on the thickness of the material by means of a regulator in the form of, for example, a lever 9 connected to plane 8 (Fig.6). With a stepped rotation of the lever 9 in the direction C, the plane 8 rises, and with a rotation in the direction D it goes down. Therefore, the height of the stopper 7 varies relative to the plane 8.
    The bracket can be adjusted by the lever 12 (Fig. 7) depending on the width of the sawn timber to separate the boards 57 and 58 coming in succession from the conveyor 5. When the lever 12 gradually turns in the F direction, the distance between the element 10 and the locking device increases, then as if turning this lever in direction E, the pocket becomes narrower.
    Fig. 6 shows the moment when the first board 59 is locked in a pocket, the second board 60 is placed over the first, facing the stopper 39 of the lower conveyor 38.
    As shown in FIG. 9, by means of the lifting devices 16, the side boards 61 are lifted and supplied in one or the appropriate groups dp for further processing.
