Abstract

PROBLEM TO BE SOLVED: To apply an adhesive smoothly to a veneer at a high efficiency by protecting a base board or a longitudinal core veneer against a double coating by positioning a trough right below an extruding nozzle when a cross veneer is inserted, and moving each of the veneers backward and further depositing the cross veneer on the receding longitudinal core veneer and conveying it. SOLUTION: When manufacturing an LVL product made up of a cross veneer 4 as a second member in between, first a base board 7 is conveyed as a back board and an adhesive is applied to the upper face of the base board 7. When the rear end of the base board 7 is part a position right below an extruding nozzle 1a, a trough 1c is positioned right below the extruding nozzle 1a and at the same time, the base board 7 is reversely conveyed to a specified position. Next, the cross veneer 4 whose fiber direction as the veneer 4 is conveyed is orthogonal with the fiber direction of the base board 7, is superposed on the base board 7 and then is conveyed to be stacked at a stacking site after the adhesive is applied to the upper face of the cross veneer 4. After that, either of longitudinal core veneers 5, 6 is conveyed and is stacked on the earlier stacked cross veneer 4 after applying the adhesive to the upper face of the longitudinal core veneer 5 or 6.

In the above-mentioned prior art, a plurality of filaments are horizontally stretched somewhat below the veneer conveying line in communication with the carry-in and carry-out conveyors of the top coater. Since there is no problem at the start of work, the adhesive adhering to the line just below the top coater thickens over time and hinders veneer conveyance, and the veneer stops when time elapses In many cases, the adhesive does not enter the glue receiving box immediately below and leaks around. Therefore, there are problems such as a decrease in productivity and a decrease in the yield of the adhesive.

Next, when the set number of the vertical core veneers 5 or 6 is completed and the cloth veneer 4 to be positioned as the second product from the top of the intermediate product is supplied, the fiber direction is set to the carry-in conveyor 2 in the transport direction. Is supplied in the same direction as the vertical core veneer 5 or 6, and the fiber direction transferred by the standby first supply device 8 is changed to the vertical core veneer 5 or 6 in the same manner as in the case of the original plate 7. A single veneer cloth 4, which is in a direction perpendicular to the fiber direction, is placed on top of the vertical core veneer 5 or 6 (in this case, the single veneer cloth 4 is the second sheet from the intermediate product). And vice versa, directly under and directly below the extrusion nozzle 1a, conveyed in the orthogonal direction by the direction change conveyor 13, and further supported and conveyed from below by the in / out conveyor 14 to the vertical core veneer 5 at the deposition location. Or deposit with 6 veneer facing down and veneer veneer facing up Those (see FIG. 5 (E to G)). Next, the original plate 7 serving as the front plate is conveyed to the carry-in conveyor 2, but the adhesive is not applied on the original plate 7 serving as the front plate, so that the gutter 1 c is positioned immediately below the extrusion nozzle 1 a and passed onto the carry-out conveyor 3. The directional change conveyor 13 and the in-and-out conveyor 14 are operated to mechanically deposit on the cloth veneer 4 previously deposited (see FIG. 5 (H)). When producing an LVL product in which the cross veneers 4 are put in places other than the second upper and lower sheets, the operation shown in FIG. The floor plate 12 is supplied from the floor plate supply device 11 onto the carry-out conveyor 3 each time so that the floor plate 12 is located at the lowermost surface of the accumulation of the intermediate product 15 and at the intermediate position for each predetermined mechanism, for example, at the intermediate position for every ten mechanisms and the uppermost surface. Then, they are sequentially and mechanically deposited in a preset order by the direction change conveyor 13 and the in / out conveyor 14. Further, the vertical core veneers 5 and 6 have piles which are inverted from the vertical core veneer 5 and the vertical core veneers 6 are alternately supplied from the two piles to prevent warping of the finished product. In addition, when the pile of the vertical core veneer 5 is exhausted, the pile of the vertical core veneer may be supplied supplementarily so as not to reduce the production. Needless to say, a well-known holding device or the like may be added to this, so that the vertical single veneer can be supplied without interruption to prevent a decrease in productivity. Further, an aligning device is added to each of the first and second supply devices 8 and 10 so that the position of one end in the direction orthogonal to the transport direction can be accurately adjusted when the first and second supply devices 8 and 10 are placed on the respective conveyors 2 and 9. Needless to say, this may be done. Although not shown, it is a matter of course that a detector or the like is provided in each section, and that a detection signal is transmitted to a control circuit for controlling the entire apparatus to operate each section according to a preset mechanism order.

According to the present invention, an upper surface applicator for applying an adhesive such as an extruder to the upper surface of a veneer, and a carry-in conveyor and an unloader which can be moved forward and backward and intermittently arranged before and after the upper surface applicator. Conveyors, cross veneers arranged on one side of the carry-in conveyor and vertical core veneers arranged on the other side of the carry-in conveyor are placed one by one from the upper surface of the stack at predetermined positions on the carry-in conveyor, respectively. A first supply device for supplying, a transport conveyor disposed on the loading side of the loading conveyor and capable of being transported and intermittently driven at the same speed as the loading conveyor, and a top plate disposed on one side of the transport conveyor or A second supply device for supplying an original plate such as a back plate and a single vertical core plate disposed on the other side of the conveyor one by one to a predetermined position of the conveyor from the upper surface of the stack, and the unloading conveyor; A bottom plate supply device for supplying the bottom plates arranged on one side of the stack one by one from a top surface of a stack to a predetermined position of a carry-out conveyor at a preset time, and a bottom plate disposed between the rows of the carry-out conveyors on the carry-out conveyor. A turning conveyor that turns each veneer arriving at an orthogonal direction each time, and supports each veneer that is disposed between the rows of the turning conveyors and conveyed on the turning conveyor from below. It consists of an incoming and outgoing conveyor placed on a pile each time.When inserting a veneer, extrude an original plate such as a back plate or a top plate or a veneer veneer that is strong in the transport direction where the adhesive is applied. After the gutter is positioned just below the nozzle to prevent coating twice, each veneer is retracted and a veneer cloth having no strength in the transport direction is placed thereon and transported. Because it is a line, etc. The adhesive can be smoothly and efficiently applied to the veneer without disposing, and the apparatus is simplified, troubles at the time of transport are eliminated, and prevention of a decrease in productivity and a decrease in the yield of the adhesive are eliminated. This is a very remarkable implementation effect.
