(54) Equipment for automatic raking of delays in disassembly of timber

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatic raking of inserts in disassembly of the interleaved sawn timber, in which the upper layer panels are taken up by chains with grippers.

The timber stacks composed of boards are interleaved with wooden inserts to allow even drying of boards naturally or in kilns. After drying, the stacks are fed to blanking platforms for lifting or tilting platforms to disassemble the individual layers of the sheets and further process them on short cuts or slitting saws. Lifting platforms are known in which the top layer sheets of the stack are gathered by chains with grippers. After each layer has been summarized, the inserts are removed manually and the platform is automatically raised by the next layer to the starting position. In the case of folding platforms, the folding platform is tilted to an inclined position, from which the upper layer plates can slide on the roller conveyor by shearing or sawing due to their own weight. The inserts fall on a belt conveyor located between the tilting platform and the saw conveyor. The disadvantage of folding platforms is the possibility of simultaneous sliding of more boards on the saw conveyor, in platforms with folding chains the disadvantage is the manual removal of inserts.

These drawbacks are eliminated by an automatic ripping device for disassembly of the interleaved sawn timber in which the topsheets are

201 249

201 249 is summarized by chains according to the invention, which consists of a pivotable folding lining bar, a pivoted knee of the pins, a spring suspension and a copying pulley which is fixed on a return trolley connected to a pull chain guided over the chains. to the support rail on which the copy template is attached.

Automatic folding of the inserts with the swiveling rake provides further automation when disassembling the cutting units, eliminates the physical effort and shortens the time required to remove the inserts ·

In one embodiment, the device is shown schematically in the accompanying drawing in FIG. 1 in front view, in FIG. 2 in plan view and in FIG. 3 is the drive of the carriage with the scraper bar.

The device for automatic raking of the interleaves consists of a swiveling, spring-loaded, folding bar (13), provided with a copying roller (20), mounted on a return trolley (12), pulled along the timber log by a traction chain (11). and a driven geared electric motor (8). At the extreme dead center of the carriage (12), the scraper bar (13) is raised by approaching the roller (20) on the copy template (19).

The edge 2, consisting of plates 2 interlaced with layers of interleaves 2 3®, is placed on a liftable platform 2 * The individual layers of plates 2 are successively folded together by means of rake chains 2 with grippers 6. In order to prevent folds 2 »3 supported on a vertically adjustable supporting rail 2 * After the transverse summary of the top layer of plates 2 swath chains 2 ⁰ scrapers 6 fall folding chains 2 by its own weight Dale board layer 2, edges 2 ^FL ® liftable platform 2 will automatically rise to the next layer, and a sweepout chains 2 is lifted partially to allow longitudinal folding of the inserts 2. To lift the folding chains 5, depress the undrawn limit switch, which gives an impulse to start the geared motor 8. By rotating the chains 2 »10 and pulling the chain 11, the trolley is pulled 12 with a swiveling scraper 22. »which The stack 12 pushes the undrawn limit switch, which will give an impulse to the reversing of the geared motor 8 and return the stacker 12 with the swiveling rake 13 to the starting position. The swiveling swath 13 is pivotable about a pivot 22 around which it folds out when the rake is weighed in and allows copying of the surface and the curved plates 2 when folding the inserts 2. With the nut 18. The swiveling swath 13 is secured to the curved surface of the plates securely by the copying template 22. mounted on the support bar 2 at the beginning of the rake 2 * Swinging rake 22 j® n® at the beginning of the rake above the surface 20 by a copying template 22, with which it slides down to the surface of the plates slowly prior to the folding of the inserts. When disassembling a play 2 of equal length, the interleaves 2 can be folded alternately on both sides into the magazines 21 ^and 21. This eliminates the waste time for returning the carriage 12 with the swiveling rake 22 and the starting position to the beginning of the play 2.
