The invention relates to an apparatus for turning only. Specifically, the apparatus in connection with the Kent saw saw, wherein the sawed sheer or similar piece of wood sawn from at least two surfaces can be rotated in a controlled manner about its longitudinal axis 5 most preferably 90 degrees.

When cutting timber, various devices have been developed to handle it at different stages of the sawing process, with the aim of reducing the amount of labor needed, making the work easier and speeding up the sawing process. In particular, various mechanical solutions have been developed for handling (moving, turning, removing, sawing) timber in connection with a sawing operation.

Previously, only the turning could have been done manually by hand over the sawing table. Another option has been to push just the back of the log using the positioner. The log conveyor is used to mechanically position the log on the saw table. For positioning, two hydraulically actuated curved arm portions are generally used which are hydraulically movable on both sides of the log table saw, the first of the arm portions supporting the log while retaining it in its lateral position and the other rotating the log into its desired position by rotating the girder. The other arm portion is also utilized for lateral positioning of the log,. 20 on top of the cutting table. Such devices are widely used and their technology is known.

In Figure 1, there is only 1 on the field saw or similar saw table 2 waiting to be turned. The field saw consists essentially of a frame 3, a saw table 2 on which it is moved, and a circular saw (not shown) for sawing the log table, moving the log, and / or simply lengthwise. Means for moving and positioning the log / plaque for sawing, ie the log displacers 4; 4a, 4b are in a resting position below the surface 6 of the saw table. The left-hand first 118957 3 support shifter 4a consists of a shaft 7 mounted at its first end 8 to a gear device 10 rotatably connected to the body 3 and to its second end 9 The right-hand support shifter 4b also comprises a shaft 5 having a similarly end-bearing bearing. 12 to the frame 3. With the gear gear 10 of the first 5 log conveyors 4a, the log can be rotated about its longitudinal axis 11 on the saw table 2 while being supported on the opposite side by the free end 19 of the second log conveyor 4b; The movement of the arms 4a, 4b from below the level defined by the surface 6 of the saw table to the working position on the saw table 2 and back is effected by a power train such as two hydraulic cylinders 7a, 5a 10 (shown in dashed lines in Fig. 1).

The apparatus according to the invention for turning only comprises a power-driven arm 5, a gripping member 14, a plurality of support members 21 and means for lifting the support members 21 above the plane 6 of the saw table surface. In this embodiment, the arm 5 is the arm of the second support conveyor 4b, but it may also be a separate arm powered by its own power unit 15, which is moved transversely to the longitudinal direction of the saw table and its direction of movement. However, it is preferred that the arm 5 and its powertrain are part of the support transmission 4b. A gripping member 14 is attached to the free end 13 of the shaft 5. This gripping member 14 is preferably a narrow elongated claw-like member, hereinafter referred to as a slide tip. The gripping member 14 is a substantially tan-20 comical or plate-shaped body articulated by a hinge 16 at its distal end 15 relative to the sole 15, at the opposite end of the gripping member 14. The same longitudinal side 18 as the hinge 16 is sharp tip 19. The edge 20 adjacent the pointed tip 19 is preferably rounded or bevelled to facilitate use of the log conveyor 4b for its other function, which is to position the log. In this case, the round - * "*: 25 crossed / bevelled edge 20 does not grip the surface of the log, but the surface of the log slides smoothly: ** [: against the surface 29 of the gripping member 14. The gripping member 14 may also be thicker: ***; 16, which provides better support against the log, and the surface 29 of the gripping member 14 may be shaped slightly concave to conform to the round surface of the log.

In one embodiment of the invention, there is a biased spring 30 (illustrated in Figure 3) between the gripping member 14 and the end 13 of the arm 5. This spring 30 holds the need ···. the sensing member 14 in its resting position pressed against the inclined head 13 of the support shifter 4b. When the sole 1 is poured, the gripping member 14 opens outwardly against the spring *: force of the spring 30 and returns by the spring 30 against the inclined head 13 of the arm. The spring 30 secures the gripping member 14 against the end 13 of the shaft 5 when the gripping member 14 is not used for mere felling. However, it is possible for the spring 30 to be completely omitted, since it has been found that the gripping member 14 functions as shown in the case of a single fall alone, even without it. However, when the arm 5 is used as a support shifter, the spring 30 ensures that the gripping member 14 does not interfere with the transfer functions.

The support members 21 are tracked on the saw table 2 in a straight line at a distance from one another in its length. In preparation for incoming felling alone 1, support members 21 spaced apart in the longitudinal direction of sawing table 2 are lifted upward from the plane 6 of the saw table, upwards from the plane 6 of the saw table. The purpose of the support members 21 is to prevent the transverse movement of the sole 1 only during the tipping. Most preferably, the supporting members 21 are raised slightly from the plane 6, such as 1 to 2 cm.

Preferably, the support members 21 are part of the transverse transfer means, i.e. the lever arms 31, but completely separate support members can also be used for the same purpose. Hinges 31 are normally used to move (drape) sawdust or even finished sa-15 lumber transversely away from the saw table 2. The hinges 31 comprise a plurality of spaced apart bars 32 disposed transversely to the $ a fun table 2 between its cross members 2a. The rods 32 are mounted on a pivot shaft 33 which is pivotally mounted with bearing bushes 34 on the side of the saw table 2 in the direction thereof. Most preferably, the shaft 33 has a hand crank (not shown in the drawing 20a) for rotating the shaft and thereby raising the parallel rods 32 inclined with respect to the bearing point when the saw table 2 is to be emptied *: * ·; for example, any remaining sawn waste after the sawing operation.

! In this embodiment, the support members 21 are implemented by means of a rod 32 of a lever bar, in particular by the free ends 32a of the rods 32. Supporting members 21 so. The free ends 32a of the bars 25a, in the case of 1 alone, are raised above the plane 6 of the sawing table 2 by a suitable lifting device 33 (cf. Fig. 4) and lowered at least below the plane when the support members 21 are not needed.

In Fig. 2, the arm 5 of the right-hand propeller 4b is displaced by its hydraulic cylinder around its bearing point such that the pointed tip 19 of the gripping member 14 has hit the sawed vertical side 22 of only 1 and has begun to dump only increased in a controlled manner: around the free ends 32a of the supporting members 21, i.e. the bars 32. The bars 32 are hinged at their opposite end 28 by means of an axis 33 to the saw table 2 as described above. The ends 23 of the support members 21 support the sole 1 only so that the sole does not move in the transverse direction during tipping. The sharp tip 35 of the gripping member 21 remains stationary on the vertical side 22 of the sole 1 only. The distance of the impacting member 118957 5 of the gripping member 14 measured on the vertical side 22 alone is substantially slightly smaller than the width of the bottom side 24 alone. When the mere 1 begins to fall around its corner 26, the gripping member 14 disengages from the end 13 of the arm 5 by pivoting about its articulation 16.

5, in Figure 3 alone 1 is in its fully overturned position and support members 21 have returned to their original position. The return of the support members 21 to their rest position is automatically caused by the mere fall of the support member 1 over the support members. Throughout the felling, the sharp tip 19 of the gripping member 14 has remained attached to the sole 1 alone and thus falls over the support members 21 in a controlled manner so that it does not need to be completely reworked again, and sawing can begin quickly. When the sole 1 is completely overturned as shown in Fig. 3, the arm 5 is returned by its hydraulic cylinder 5a to its rest position under the saw table 2 to the position shown in Fig. 1. As the arm 5 begins to recover, the sharp tip 19 of the engaging member 14 slides along the vertical side 22 of the sole 1, which is now horizontal, and after passing the angle 25 only, the pawn 15 is lowered against the end 13 of the arm 5 thanks to a prestressed spring 30.

The arm 5 can also be used without problems for its original purpose, i.e. to move the log or the lumber in the lateral direction or to hold the log in place when the log is rotated from the opposite side by a first log conveyor 4a having a gear 10 secured to the arm 7. grasp the round surface, but the surface ·: ··: must be substantially vertical so that the tip of the gripper engages the surface.

* · «··! Fig. 4 illustrates a lifting device 33 for lifting the support members 21 up / up from the surface 6 of the saw table to support the opposite lower angle * 25 of the lower corner 25 only 1 during the felling. The supporting members 21 in this example are the bars 32 of the lever bar 31, which is typically a piece of flat iron whose other free end 23 is now lifted from the surface of the saw table 6. The lifting device 33 includes an auxiliary bar 34 with upright V projections 35. in its longitudinal direction so that it is free to move vertically back and forth. 30 between two positions, the rest position and the work position. The auxiliary bar 34 is stiffened below the lever bars 32 and with the projections 34 at the lever bars ·, "·· * 32, preferably near their free ends 32a. The lifting device *: · *: 33 further includes a lever mechanism which is preferably two-piece. Lever Mechanism 36; 36a, 36b The parts 36a, 36b of the Lever Mechanism 36 are connected at their upper members 35 by a lifting rod 37. The lifting rod 37 is a straight rod which is disposed beneath and parallel to the auxiliary rod 34. most preferably 118957 6 in the area between the saw transfer rollers below the saw table 2. The supporting members 21, in this embodiment the free ends 32a of the bars 32, are raised to the working position upwardly from the surface 6 of the saw table 2 by pivoting the lever 36 so that -5 is upwards, whereupon the auxiliary rod projections 35 raise the support members 21 el i bars 32 up from plane 6 of the surface of sawing table 2. When the sole 1 is poured by the gripping member 14 against the support members 21, i.e. the free ends 32a of the bars 32, the beam pushes the support members 21 / bars 32 and further to the auxiliary bar 34 and lever mechanism 36; 36a, 36b and release it from the workstation, whereby the supporting members 21 / rods 32 sink to or below the top surface of the sa-10 table. Thus, by acting alone, the support members 21 / rods 32 are automatically released and pressed below the saw table without further action.

The supporting members 21 can be implemented without lever arms 31. Thus, in a preferred embodiment, the projections 35 or the corresponding pins 15 of the auxiliary bar 34 of the lifting device 33 are directly operable to act as said supporting members 21.

The invention is not limited to the embodiments disclosed herein, but may vary within the scope of the claims. Several functional solutions can be found for the design of the gripping member, of which only a few are exemplified herein. It is essential that the mere fall is carried out in a controlled manner by the gripping member pressing-20 clubs against and around the supporting members resting only on its lower part, such that:: *: the fall is accomplished.
