Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for processing a veneer cut by veneer lace, especially a loose veneer or a continuous band-shaped veneer cut as a stone plate or back plate of plywood, in a veneer lace line. Regarding.

The conventional processing of these veneers in a veneer lace line is to cut the cut veneers to size or length, and then transport them suspended by a needle conveyor or a forked vacuum conveyor/veyor, and deposit them on a pile pile. It was done by the method of A combination of these methods is that a knock-off bar is used to release the veneers from suspended conveyance in order to ensure orderly stacking. In order to smoothly and reliably process the MiL plates that are continuously being cut, there is an unavoidable narrowing that slows down the cutting speed of the veneer lace, which reduces the processing capacity. There were disadvantages such as damage to the veneer as well as damage to the veneer. In addition, in the conventional method, the softening (tenderizing) treatment of these veneers in the veneer lace line is carried out by cutting the cut veneer to a certain size or a fixed length. Because it is difficult to completely match the veneer feed speed of the softening device with the 1" cut of the board,
The problem was that the veneer could tear or fold over itself.

This %lighting is aimed at eliminating the drawbacks of the conventional method and VC.
The invention will be explained by the examples shown in the drawings below.

The veneer race/ is used to cut a veneer using a cutting tool from a raw wood 3 that is supported and rotated by a spindle with a chuck, where j is a nose parr, 6 is pure white, and 7 is a pressure plate.

The small, medium, or continuous band-shaped veneer A that has been cut by the cutter is conveyed to the cutting device // by the conveyor roller, co/peyata, and conveyor 10 arranged in iC sequentially from the cutting position of the veneer race/. .

The cutting device// includes, for example, a rotary first cutting machine 12, a first cutting machine/3 arranged in tandem with this, and a W'rN conveyor// that conveys the cuttings of the veneer A across the front and back of the cutting machine. 44
The pricking conveyor is composed of a surface pressing roll 15 and a veneer detector 16, and cuts the veneer to size or length while conveying the veneer at high speed. The veneer detector 16 is commonly used for cutting the veneer.
If the length is longer than the standard dimension, a cutting signal for cutting to a standard length is transmitted, and these detection signals are transmitted to the operating soaking barrel 17 to raise and lower the suppression roll/S to cut the veneer Z. The needle-like body of the needle-shaped conveyor/Hiro is stuck to the effective part of A so that the leather-like A is sent 7M'fjri, and these shide-yugo are used to make sea bream/g or operating mechanism 19. Tell me about the first disconnection/
2 or the first cutting machine/3 is driven to rotate, and the cutting blade 20 cuts the veneer A to a certain length or to a fixed length. For example, in the first cutting vessel 12, d! , the edge cutting is carried out in the first cutting mode /2, cutting the front end of the veneer A to a certain length or cutting it to a certain length. Since the cut and separated waste veneer A1 is not stuck, it is removed from the conveyance path along with the cutting and separation, and the sized veneer AI, which is an effective veneer, is removed.
Alternatively, the fixed length veneer 2 is inserted into the pricking conveyor, reaches the end of the pricking conveyor, is released from the conveyor 7 by the release pulley 27, and is transferred to the next conveyor.

Following the conveyor U, a softening device is arranged, and the unsoftened device fi, 2J is, for example, a softening roll made of a rigid or flexible body of the same or different diameter, 2! , J' are arranged vertically opposite each other, and a large number of fine cracks are generated in the sized veneer A/or the sized veneer A- passing through to make it flexible.

Flexibility - Conveyor J is placed next to I, and conveyor 5 is equipped with an actuator ##J, and the actuator roller is a cutting device using a veneer detector/6. L cut-[
operates based on the detection signal of south size cutting or standard length cutting, and the conveyor 65 is rotated to sort the sized veneers AI to the upper conveyor 27, and the regular sized veneers A and 2 to the lower conveyor 27. conveyor 2g
Each of them can be shrunken.

Following the upper conveyor core, there are 9 take-up/veyor 29 and Suzu, and the total number of take-up conveyors is the start car 29.

From the upper part of the rear end, turn the top part to a position as close as possible to the lower end of the front end or lower part of the front part.
For example, the starting wheel 30 & is attached to a support rod 36 that swings around the axis 3S of the prowler 30b so that it can run while contacting the circumferences of the moving wheels 30b, and the end wheel, ? Yugun, Og? These winding 9 conveyors 2q and 30 are attached to a support rod 3g that swings about a shaft 37 of Of, and form a conveyance path that travels around at least ten circumferences of the reel 3/or winding ball 32 while being in contact with the winding ball 32. That's what I do.

In addition, in the winding conveyance q4C, the elastic body 3 is connected to the tension wheel 2b, and the elastic body θ is connected to the support rod 34! Tension is applied to each to bring the endless firefly into close contact with the outer circumferential surface of the reel 31 or the three whirling balls, and the making mechanism (g/) is made on the support rod 3q to wind the reel 31 or the whirling balls (32). The end wheel 29 is rotated to the position shown by the dotted line during insertion and removal from position a P, and the winding conveyor 301
In C, the elastic body λ applies tension to the tension wheel 30 d, the elastic body &J, and the support rods 36 and 31, respectively, so that the endless band is tightly impregnated on the outer peripheral surface of the reel 3/or the winding ball 32. , the actuator acts on the S-line support rod 36 to move the reel 31.

Since this joint-shoulder size veneer A/ has been subjected to a softening treatment, the leading end does not bend overlapping, and the rear end extends from the lower four groups of the reel 31 along its outer rm Upper digit 1! The ball is then guided to 1.469 by the winding slope 9 conveyor 3o via the top and front end of the reel 31, and wound onto the reel 31 to form three balls. Then, the sized veneer A/ that has been conveyed 1114th time is similarly wound up by both winding conveyors 2 and 30 o system so as to be superimposed on three winding balls. In addition, in the embodiment, the winding conveyor is divided into one set and runs in contact around at least ten circumferences of the reel 3/or the rolled ball 3λ, but the winding conveyor is not divided/the composition is three sets. The reel 31 set at the winding position tap may be divided into the above group A, and the reel 31 set at the winding position tap may be a detection point that can run in contact with the winding ball 32 around at least ten circles. Further, the reel 31 or the winding ball 3λ may be rotated by the contact running of the winding conveyor, or the reel 31 or the winding ball 3λ may be rotated separately.

Advance it until it touches the surface (Figure 1). The adhesion roll j- rotates as it comes into contact with the outer circumferential surface of the rolled ball 32, and the temporary fixing member data is pushed out, and its tip touches the interface between the outer circumferential surface of the rolled ball 32 and the last sized veneer A/. When the temporary fixing member is pulled out around almost the entire circumference of the winding ball 32, the on-off valve
The pot-melt adhesive G is discharged from the nozzle 55 and dripped onto the temporary fixing member 1 in its molten state, and the temporary fixing member 4 is quickly assimilated by the hot melt adhesive G.

t is applied, and the tip is layered on the outer circumferential surface of the rolled ball 32 using hot melt adhesive G, thereby winding the tip.

In addition, as a means for temporarily fixing the three rolled balls with the temporary fixing member, a belt-shaped body having a length approximately equal to the entire circumference of the three rolled balls with needle-shaped bodies attached to both ends is used. After doing this around almost the entire circumference of the 3 rolling balls each time, stick the needle-like object around the outer circumference of the 3 rolling balls 3.
You may also perform ib stop.

The winding ball 3.2 which has been temporarily tightened operates the NJJ mechanism da/and the operation@4slls, and the end wheel 9 and the starting end wheel 3.
Rotate the 0° to the position indicated by the dotted line in the figure, take out the MF) to the deck 6/ for rolling soil, store it in the deck 6/, and move it back to the next process. When the feeding is finished, the next reel 31 is inserted from the reel deck 62 to the J picking position P and set, and the end wheel 270 and the start wheel 30

For sorting, the fixed-length veneer A2 fed to the lower conveyor 3 by the conveyor O is processed in the same way as the case of the sized veneer AI, so a detailed explanation will be omitted, but following the lower-level conveyor d. A winding conveyor (not shown) is provided, and the rolled balls are superimposed on the reel and wound up, and the rolled balls are temporarily fastened by a temporary fastening member and sent to the deck. In the example, the sized veneer A/ and the sized veneer A2 are processed separately as rolls, but if a continuous docker is installed as the next step, Plate AI and standard size veneer A
2 can be mixed on seven reels to achieve a cumulative winding total of h8.

As mentioned above, this precedent is a method for processing low-quality veneers that are produced in individual or continuous pieces cut by veneer lace, and after cutting these veneers to size or length, Alternatively, since the winding conveyor that runs in contact with at least 10 circles of the rolled ball wound on the reel automatically rolls it up and winds it up, these veneers can be cut according to the cutting speed of the veneer lace. It is possible to perform cylinder speed treatment, making it the perfect place for veneer lace! The N15 force has been significantly improved, and since it is wound onto a reel, smooth processing is performed without damaging the veneer, and since the rolled ball is temporarily secured with a temporary fixing member, the movement of the rolled ball is smooth. There are no problems such as the veneers coming off the roll, and the processing and feeding of these veneers to the next process can be carried out fully automatically.
Since the unsoftened veneer is cut to size or cut to length, the veneer can be softened smoothly on the veneer lace line and without causing any damage to the veneer. , making a great contribution to the plywood industry.
