Description

DETAILED DESCRIPTION OF THE INVENTION This article relates to a method of manufacturing plywood in which the narrow decks produced in one culm are not combined, but are used for the core core.

Conventionally, the small width veneers generated in the Shirane manufacturing process were applied to one sheet by applying force (J-uni-kumi, 7 layers, 4 pieces,
You can put these pieces together to make a wide sheet, or you can make a narrow deck that came out of the dryer. (J, Gidaiwaguchi C is used, but the processing of this small width veneer is 4ty, and the manufacturing process is d; L-J) There is a big problem. How to do this in a rational manner will have an impact on the production process as well as on the wood yield.
There was T.

Hokomei is a method of combining small width veneers into a single piece of wide medium veneer without joining them.
By using small width veneer efficiently,
The manufacturing process has been streamlined and simplified.
+! There is a paper whose purpose is to provide a manufacturing method.

In the present invention, the drums are assembled in the same plane and are cut in advance into a 1-1 shape of type 1 or 2-1 or more so that they are assembled on the same plane and combined to form a single wide deck. [σ to 2

Below, I will explain Kikomei to CiT All using drawing [2].

Figure 1, Figure 2, Figure 3 and Figure 4 (Mulsu [Each center 141 substituted by the constant X1 method) A small explanatory diagram showing an example of the condition, Fig. 5 shows an example of a narrow deck assembly. This is the first explanation.

Medium and small width fresh root for the center core used for Kikomei C (J, conventional baseplate pickled soil grade - C light production - Ruru size, small width veneer with various shapes (J strike, li raw small width Dry the deck and crystals that may form before use.

Next, cut the generated small width LIE board into a regular shape according to its size and shape.
Di L, drill two or more circular holes at certain positions to make the center core unit narrow +4. i temporary and jru. The above 1s1 regular shape and ta
The shape makes the most effective use of each of the 14 IA raw narrow width boards of various sizes and shapes, and the 11 sheets manufactured in this way are units for cores of two or more types. A single wide deck is made by stitching together a small number of small (medium) pieces on the same plane to form a single wide deck (111), which is shaped like a monkey.

In addition, the fixed shape of each of the plurality of core unit narrow width decks that make up a single wide deck is the size and shape of the generated narrow width middle plates.
(Medium-sized small 911-1
Next, an example of a single wide veneer in which 1kari are combined will be explained. The example of the J--flexible wide deck 1 shown in FIG. Ii
Two circular holes 12 (!, - drilled I
This is made up of 11 pieces of unit small width veneer plates 11 for the center core. (See Figure 2, Figure 3, and Figure 4 for η. Examples of flexible wide deck 1 are 3 sheets of 2 types each,
It is composed of 4 pieces of 3rd type and 4 pieces of 2nd type medium 10 narrow width veneers 11 for the core, and uses a small R raw narrow width deck.
In this case, - wedge-shaped wide veneer] (111 pieces) 1 number of unit small width medium plates 11 for core of silk (4 winters. C - Part of a unit narrow deck for core core made up of multiple wedge-shaped wide decks 41
It doesn't matter if they all have the same shape.
It is possible to make a quadrilateral with the shape of 114 as 1.4', a).

One or more types of these types: Ainaka 1rZ narrow decks/! Equipped with A, narrow medium plate III combination j
(The device r1 may be abbreviated as the deposition device hereafter.)2
Use one to form a single, wide 111 provisional word.

If[(ifi device 2 shows an example in FIG. 5 and FIG. 6), the position fixing locking rod 21 and position A support in which the stacking plate 22 and the locking rod 21 for fixing the position are identified at their lower ends! A 4
It is structured as 2M 23 Do to Ju. The position where the position fixing locking rod 21 is fixed to the support board 2; 3 is as follows.
The prepared unit small-width veneer 11 for the center core of the prepared type 1. circular hole 12
Corresponding to the position d5, the thread stopper rod 21 for fixing the 1st position 111 is fixed at a predetermined position for each of the plurality of center core +-1i narrow decks 11. Follow-C5
Using one such deposition device 2, the locking rod 2 for fixing the position is used.
1 corresponds to that position. The narrow deck 11 is locked and fixed in a predetermined position by a position fixing locking rod 21, and the iJ-soft wide deck 11 is held there.
The layers above are attached to the position fixing locking rod 21 (111) for each center core for medium and small widths (because they are automatically formed by the opposite number of sheets and the number of turns (V).

Then the suction tube II device (with 16 suction units)
(not shown) adsorbs the top layer of the single wide deck 1 formed on the soil of the veneer pile plate 22 of the Ri system 2, and creates two or more medium and small width veneers 11 for the center core. Hold the combination state J and move -C. Desirable 1! Ii Release the suction at a certain place, stack another wide veneer coated with adhesive and a specified plywood (M configuration), heat and press according to the usual method to make plywood. -There is C.

Nakaboard if detective 2? After the first single wide deck 1 above is sucked and moved, the single wide deck 1 of No. 2 L1 becomes the top layer, and the above-mentioned sucking and moving 71 -
It is difficult to manufacture plywood one after another over and over again.

The top of the single wide single plate 1 formed like a mouth on the single plate stacking plate 2211 of the trt reconnaissance device 2 and scanned.
The level of one layer does not necessarily have to be constant C. Use the suction device while squeezing - Easy suction, movement, etc.
It is preferable to always maintain the upper layer at a constant level.

(-, therefore, the veneer stacking plate 22 is used as the 1" stacking device 2 (C

After the veneer stacking plate 22 is moved up and down to position the single wide deck l of the top layer at a certain level, and placed on the suction. NiJ,

You can do that.

The Mokkomei method has the following effects. Tsunawara, j

You can move up to the age of 11. The manufacturing process has always been streamlined and simplified. (Circular holes drilled in the unit small-width veneer for the center core (as they exist only in the center core in one layer, there is virtually no problem with the plywood product v1.) , Since the shape of the medium narrow medium plate for the center core is set in advance, various shapes of 4φ such as UC, J square Ab good rectangular shape and arbitrary shape 4ju shape etc. are set in advance.
l [Next Shirane manufacturing process C] Select a shape that makes effective use of each narrow-width middle plate that occurs, recess a crosspiece in that shape, and use it as a unit narrow-width deck for the center core. In other words, J, S, R1 narrow middle root is used as -9) J 'i・' to form 1j.
C contributes to improving the yield.
