Machine for profile working of front surfaces on oblong wood workpieces

Machine for profile working of front surfaces on oblong wood workpieces, constructed of the transverse entrance and exit roller conveyor and intermediate feed line conveyor drive by means of the endless conveying chain, inside which there is placed a rotating device for turning over workpieces, constructed of the drive-shaft and upon it fastened rotating wheels, and along with the intermediate feed line conveyor there are side guiding laths for front straightening of workpieces, and fixed working units, by which the workpieces move lineally in the way that they lie perpendicular to them, and are thereby rigidly clamped in the clamping unit, whereby working units are formed by the circular saw and profile miller in the given series, is characterized by the fact in which there are along the entire extent of the optional number of rotating wheels of the entrance turnover device, in spacing and along the entire extent, constructed bearing couplings with rotating leaning rolls inside the bearing plate, at least on one preferentially front rotating wheel, there are likewise along the entire extent constructed bearing couplings with two pairs of rotating leaning rolls and inside bearing plates, which are circularly movably fastened on rotating wheels in the rotating point, while their guided bearing is movably and guidable placed by the external edge of the guiding plate or inside its groove which round up the guiding plate on its major extent, whereby there is preferentially at each rotating wheel constructed at least one guiding plate;

• in which the endless conveying chain that runs between the longitudinal conveyors with carriers has preferentially on each of its link constructed and through the housing fixed on it at least one clamping unit, which is longitudinally limited by at least two, a trifle distant one from another and fixedly positioned vertical ribs, whereby at one there is fastened the fixed leaning plate, and opposite to it there is fastened the clamping mechanism with a pair of shears-like constructed cranks, which are with one of its end radially movably and through the pin rounded up by the return spring joined in the joint rotating point, and with the other end they are likewise radially movably, but separately and through the rotating point joined by at least one clamping cylinder with the jaw, while on the opposite side of the housing basic plate of the clamping unit there is placed the mirror-inverted fixed pair of side guides with inserted guide bearings of the endless conveying chain, and from the external side there is upon the side guides fixed the girder with at least one control field and control indicator adjacent to it;
• in which there is placed in the entrance turnover device area, and a trifle over clamping units on the endless conveying chain, at least one oblique roller conveyor with the housing, inside which there are flexibly and circularly movably inserted at least one knurled roll and at least one smooth roll in the way that their longitudinal axes limit the internal angle, as a rule smaller than 180°, whereby, they are with one of its ends together rotationally and flexibly joined in the rotating point by the oscillating lever, which is through the rotating point radially movably joined with the girder, and through the rotating point radially and lineally movably joined with the cylinder fastened to the girder in the rotating point, while by the opposite end the rolls are likewise rotationally and flexibly joined with cantilevers or respectively, which are in the longitudinal and transverse direction flexibly inserted in the adjacent oscillation stabilizer, whereby the knurled roll is through the chain driven by its own drive, and the smooth roll is through the chain adjacent to it driven by its own drive;
• in which the rotating wheels of the exit turnover device are constructed in the chain wheel form with an optional number of toothed outgrowths placed all over the rotating wheel, under an optional angle tilted in the direction opposite to the rotation, whereby there is preferentially on the top of each toothed outgrowth and in the rotating point radially movably fastened at least one bearing crank, which is through the endless chain connected with the control chain wheel, upon which there is fixed at least one control panel and is together with it circularly movably fastened to the rotating wheel basic plate in the rotating point in the way that they are positioned a trifle under the toothed outgrowth, and that the movable bearing placed on the top of the control panel is rotationally and guidably inserted inside the channel guide, which is placed on one of larger surfaces of the rotating wheel and parallel to it, and that it is fixed on the girder.
