Dimensional cutting and abutment mechanism for continuous veneer etc. and glue nozzle 9
Of the hot-melt resin A by the hot-melt resin A and the cold-pressing mechanism of the hot-melt resin A by the pressing and cooling bars 10a and 10b and the detection of whether veneer chips remain in the veneer joint. And a control circuit C for temporarily stopping the restart of the carry-in conveyor 2 and for giving an alarm by an alarm device Z such as a buzzer. The specific mechanism of the present invention is shown in FIG. As shown in FIG. 3 and FIGS. 4 (a) to 4 (d), one embodiment of the dimensional cutting mechanism is movable up and down to a connecting portion of a single-plate transfer path composed of a carry-in conveyor 2 and a carry-out conveyor 3. The thin knife, irregular edges, dry cracks, knot holes and other defective parts of the veneer veneer 8 during the transfer process are cut by a cutting knife 7 composed of a movable blade 7a and a fixed blade 7b installed in the middle of a sized width. Along with being molded into a product, Serial and edge cutting points after the preceding veneer 8a of the intermediate product consisting of chromatic dimension width, the subsequent veneer 8b of the front edge cutting point and the chip W on veneer joints that are set on the fixed blade 7b

作業が行われる。Furthermore, the time required from the cutting shown in (b) to the completion of the joining shown in (f) is generally required to be about 0.6 seconds or more, and the time required for the chips W to pass through the detector P is substantially the same. Since the time is less than 0.01 second, the set time for the determination of the clogging state in the control circuit C is set to about 0.01 second. Therefore, when the detector P is in the detection state for 0.01 second or more, the control circuit C transmits a signal not to restart the motor M of the carry-in conveyor 2 to temporarily stop the motor, and a warning sound is issued by an alarm device Z such as a buzzer. To prevent clogging. As a result, even if the operator supplies the veneer, the carry-in conveyor 2 does not operate, so that the subsequent veneer is not conveyed at the cutting edge and the clogging is prevented, and the operator immediately removes the chip W in the detecting portion, thereby controlling the control circuit. C is returned to the normal state, restarted, and the joining operation is continuously performed.

のである。As described in detail above, the present invention can be applied to the cutting of the leading edge of the preceding veneer and the cutting of the leading edge of the succeeding veneer at the veneer joint set at a predetermined position of the veneer transfer path. Drop separation of the chips, gluing of the molten hot-melt resin onto the joining line of the joining portion where the end surfaces of the two veneers were joined, and their cold pressure were performed alternately, and the veneer of a sized width was connected in an interdigitated manner. In a single-plate joining machine adapted to be joined to a horizontal patch product, a guide plate disposed just below the cutting joint to guide the falling of chips, and chips from both sides or either side of the guide plate And a control circuit that stops the restart of the carry-in conveyor and activates the alarm device when the detection state of the detection signal of the detector continues for a preset time or more. By applying the characteristic anti-clogging device to the single-plate joining machine The veneer clogging at the entrance and the exit of the joining portion, which has occurred at the time of restarting the carry-in conveyor caused by the conventional apparatus, is wiped in advance, and the joining operation in the single-plate joining machine is stabilized and jammed. By preventing breakage of veneers and blades, and loss time due to work for removing clogged veneers, productivity and yield are both improved, and the implementation effect is extremely remarkable.
