the pallet rod 2123 is in the initial position (i.e. above the conveying units 110) and waits for the first veneer 10 of all conveying units 110 to reach the corresponding transition position 111, and the positioning member 122 is in the initial position (i.e. retracted state), as shown in step a;
when all the first veneers 10 reach the corresponding transition positions 111, the supporting plate rod 2123 descends to the first avoiding notch 113, and the positioning piece 122 extends upwards as shown in step b;
the first single board 10 is transported from the transition position 111 to the moving position 112, and the positioning member 122 performs the longitudinal positioning on the first single board 10, as shown in step c;
lifting the supporting plate rod 2123 to lift the first single board 10, retracting the positioning piece 122, and simultaneously lifting the corresponding conveying unit 110 of the first single board 10 by the supporting plate rod 2123 to continuously convey the new first single board 10 to the corresponding transition position 111, as shown in step d;
the pallet rod 2123 moves longitudinally toward the conveyor belt 410, moving the first board 10 to above the corresponding first board placement 411, as shown in step e;
the pallet rod 2123 descends and abuts against the second veneer 20, and the downward pressure is released through the sliding sleeve 2125, as shown in step f;
the pallet rod 2123 moves longitudinally toward the conveying unit 110 and resets to disengage from the first veneer 10, and simultaneously the first veneer 10 is positioned transversely and laid on the second veneer 20 under the action of the second positioning device 413, as shown in step g;
and repeating the steps a to g all the time, thereby realizing the moving operation of the first single board 10.
The invention can realize continuous conveying, plate arrangement and assembly of the first veneer 10 and the second veneer 20 to form the plywood, has high degree of automation, stable quality, high production efficiency and low labor cost, can realize production of plywood with various sizes and layers, and has strong universality.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
