2. Description of the Related Art Today, high-quality wood that can be used as a so-called "muku wood" for structural members of wooden structures is gradually depleted, and the number of carpenters who can use such wood is decreasing. Therefore, laminated wood has attracted attention. Laminated wood has high strength and dimensional accuracy, less warpage and cracks after construction, and easy precutting at the factory, which shortens the construction period at the site, so it can be used for structures such as general houses and large wooden structures. It has been widely used as a member.

However, for example, laminated lumber such as structural laminated tubular columns is manufactured using plate materials that have been lumbered and imported, resulting in a low utilization rate of raw wood, that is, a low yield and a high distribution cost, which is expensive. there were. Today, the restrictions on forest cutting are becoming more and more severe, but on the other hand, effective measures are being sought for thinned timber and timber that have not been properly maintained. However, if an attempt is made to manufacture a laminated material using such an inferior material, there is a problem that the conventionally known method requires too much labor and the yield of the material is poor, so that it is not economically viable.

FIG. 4 is a plan view showing the arrangement of the latter half of the laminated lumber manufacturing apparatus.

FIG. 11 is a partially cutaway front view of the chain compound pressing device shown in FIG.

The following is a sequential description from FIG. The first step is the cutting step of the log 1. In this process, log 1
For example, with a cutting device such as a chainsaw, a certain length L
_It is cut into ₀ round pieces 1-1. Length L of round material 1-1
₀ is the same as or slightly longer than the single-layer laminated material when the purpose is to obtain a single-layer laminated material, but there is no particular limitation when manufacturing a multi-layer laminated material. However, if the length is too long, the yield of the material will be remarkably reduced, and if it is too short, the process will be complicated and the material processing capability of the apparatus will be lowered, resulting in an increase in cost. The desired length L ₀ when using good quality logs is usually 1.8 to 2 m.
Before and after. However, when using thinned-down thinned wood, hard-curved logs, and scraps, shorten the length appropriately.

The second step is a sawing step for obtaining the primary lamina original plate 1-4. In the preferred embodiment, the second step is to cut the round material 1-1 cut into pieces of length L ₀ into pieces with an irregular plate material 1-2 and a rectangular cross-section material 1 by a sawing machine such as a twin band saw. The process of sawing into 3 and
It is composed of a milling process for obtaining the primary lamina original plate 1-4 from the plate material 1-2 and a sawing process for sawing the material 1-3 into the primary lamina original plate 1-4. However, the above configuration may be appropriately changed depending on the shape of the log 1. For example, when using a thin round bar 1-1 or the like, it may be simply broken into an irregularly shaped plate 1-2, and when the raw wood 1 is a thick bar of good quality, then a pillar, a beam, a thick bar. Primary lamina original plate 1-4 by processing the end material generated when the plate material is ground
Sometimes.

In the present specification, when the material 1-3 is referred to as a rectangular cross section, not only is it a geometrically correct rectangular cross section, but also one side is a bread loaf left on the skin. In addition, the cross section has a so-called drum shape in which both sides are bark of the skin, an octagonal shape in which the four corners are the bark of the skin, and all the primary lamina original plates 1-4 can be ground. In this step, in essence, a rectangular plate-shaped primary lamina original plate 1-4 having a fixed length and thickness and a random width may be obtained from a given material, and an apparatus and a process therefor are It is appropriately selected depending on the shape, intended use of the product, grade, and the like.

The thickness of the primary lamina original plate 1-4 is about 5 to 30 mm, preferably 10 to 20 so that it can be easily dried in consideration of the shape and thickness of the intended product, the type of material, and the like.
It is recommended to set it to about mm. If it is made too thin, the yield of the material will be deteriorated and the whole process will be complicated.
On the contrary, if it is thicker than 30 mm, not only will it take too long to dry, but even if it takes a long time to dry,
Uniform drying becomes difficult, and some portions are not dried sufficiently. Use of a material that is insufficiently dried is not preferable because it may lower the adhesive strength or cause cracking or deformation during use of the laminated material.

The irregularly shaped plate material 1-2 is processed into a primary lamina original plate 1-4 in a certain size by a known milling device,
The material 1-3 having a rectangular cross section is cut into primary lamina original plates 1-4 by a lumbering machine such as an upper and lower gang clipper. The width and thickness of the material 1-3 with a rectangular cross section is the same as the round material 1
The width of the primary lamina original plate 1-4 is not uniform because it is appropriately determined for each lot or for each round material so that the yield of the material is maximized according to the size and the shape.

The next third step is a drying step. In this step, the primary lamina original plate 1-4 is heated and dried in a suitable drying chamber until the water content is about 16% or less, preferably about 13%. As a drying method, known drying methods such as hot air drying, reduced pressure drying, and steam drying can be adopted, and are appropriately selected according to the properties of wood. It is also desirable to carry out seasoning for a certain period after drying.

The next fourth step is a finishing step of the dried primary lamina original plate 1-4. In this step, the primary lamina original plate 1-4 is first subjected to strain relief processing on both the front and back surfaces by, for example, a break saw or a planer, and given a predetermined thickness and perfect parallelism and flatness, and then its plane shape, The dimensions are inspected, the inspection data is image processed,
Based on these results, the quality is determined and defective products are removed. What is considered to be defective is, for example, one having a predetermined uniform thickness or width, parallelism, or flatness due to pits, nodes, scratches, holes, etc. on the surface.

On the primary lamina original plates 1-4 which are regarded as good products,
Then, both side surfaces thereof are parallel to each other, and both front and back surfaces are ground at right angles. Depending on the required product grade and purpose of use, if necessary, plane finishing, etc. are applied, so that the cross section is a rectangular shape with a substantially constant size over the entire length, and there are few scratches, etc.
Primary lamina 2 with smooth front and back surfaces and both sides
Is obtained. This modified finishing is extremely important. In order to perform high-quality width-and-width-bonding in the subsequent width-and-width-grinding process, it is required that the bonding surfaces are completely abutted against each other without any gaps and completely adhered to each other. When bonded by peeling, it is necessary that the bonded secondary lamina original plate 3 does not meander, have no undulations, and be straight, but for that purpose, perfect flatness, smoothness and parallelism of the bonding surface are required. In addition, the perpendicularity with respect to both the front and back sides must be sufficient.

The next fifth step is a secondary lamina manufacturing step. In this step, a large number of primary lamina 2 are sequentially adhered to each other on their side surfaces by a width-separating press device, which will be described later, and are stripped to form a wide secondary lamina original plate 3, and then, for example, a cutting device such as a running saw. Thus, the secondary lamina 4 having a predetermined width W from the secondary lamina original plate 3
Is cut out.

When the intended product is a single layer laminated material, the primary lamina 2 is finished to form a single layer laminated material 5. For this purpose, it is recommended that the primary lamina 2 be arranged and arranged so that the front and back of the tree are alternately reversed in order to strip the primary lamina 2 in the stripping process. In addition, when manufacturing a laminated laminated wood, the front and back of the primary lamina 2 are aligned and width stripping is performed, and this is carried out in the subsequent step.
When cutting and veneering, it is recommended to stack the layers so that the front and back are sequentially reversed.

For the single-layer laminated material 5 to be a plate-shaped product, predetermined finishing processing and product inspection are performed. As finishing processing, depending on the purpose of use and grade of the product,
Trim-length trimmed, insect-proof, fungus-proof, anti-moisture-resistant, water-repellent, water-repellent, flame-retardant, chamfered, plane-finished, polished, painted, waxed, cosmetics applied, protective stickers applied, etc. It Further, depending on the case, precut processing, perforation, etc. may be performed. Inspection items include dimensional inspection, visual inspection for surface defects, bending strength test, moisture content inspection, and the like. It is recommended that these inspection data be printed on an appropriate label and displayed on the product.

When the multilayer laminated wood is manufactured, the shaped secondary lamina 4 is sent to the subsequent sixth step. The sixth step is a finger joining step of the secondary lamina 4. In this step, first, the upper and lower surfaces of the secondary lamina 4 are planarized and, if necessary, cross-cutted. Finger machining is performed on the both ends of the finished secondary lamina 4 by a known machining device, and then the fingers are sequentially spliced by a known finger splicing device to form a tertiary lamina 7.
Is obtained.

In order to manufacture the tertiary lamina 7, it can be roughly classified into the following two methods. In the first method, an appropriate number of secondary laminas 4 are finger-joined to form a tertiary laminar 7 of a predetermined length.
The second method is, as shown in FIG. 1, to sequentially and continuously finger-bond the secondary lamina 4 to be used to manufacture a long tertiary lamina original plate 6, and This is a method of obtaining a tertiary lamina 7 by cutting into a predetermined size.

It is desirable that the tertiary lamina 7 should prevent the finger joints of adjacent ones from overlapping when the layers are laminated later to obtain a multilayer laminated material. If necessary, the tertiary lamina 7 is planarized in order to remove the steps at the finger joints so as to have a uniform thickness and to remove excess adhesive and the like protruding from the surface.

The following seventh step is a veneering step. In this step, an adhesive is applied to the surface of the tertiary lamina 7, a required number of sheets are laminated until a desired thickness is obtained, and pressure bonding is performed by a press described later, whereby a large-sized tertiary lamina laminate 8 is obtained. As the press used at this time, a chain composite press described later is recommended. The thickness of the tertiary lamina laminate 8 is not particularly limited, and may be, for example, 30, 45, 60, 90, 120, 1 depending on the shape and size of the intended product.
50, 200, 300, 400, 500 mm, etc. In addition, as described above, in this veneering, it is recommended to sequentially reverse the front and back of the laminated tertiary lamina 7 for each layer. When a large number of tertiary laminar laminates 8 of the same shape are pressed, a plurality of curative sheets are sandwiched between them to stack a plurality of them.
Pressing at the same time is recommended.

FIG. 1 shows an example in which the directions of the wood fibers of the tertiary lamina 7 are all aligned in the longitudinal direction of the tertiary lamina laminate 8, and one layer or a plurality of layers of such a tertiary lamina 7 are provided. In some cases, a lamina in which the direction of the wood fiber is oriented in the lateral width direction of the tertiary lamina laminate 8 may be inserted. It is desirable that such a lamina is manufactured by cutting the primary lamina 2 having the same length as the lateral width W of the normally used tertiary lamina 7 and cutting it to the same length as the tertiary lamina 7. In addition, a reinforcing material such as a wire or a wire mesh may be inserted at an appropriate position of the tertiary lamina laminate 8.

The final eighth step is a finishing step.
In this step, the large-volume multilayer laminated wood 8 is formed into an appropriate shape,
The lumber is sized and finished on its four or six sides with a break saw or a planer.
It is intended to obtain a multi-layer laminated lumber 9 used as a beam material, a thick board material, a furniture material, or the like. In addition to the above finishes, insect repellent, antifungal, moisture-proof, water-repellent, water-repellent, flame-retardant, chamfering, plane finishing, polishing, painting, waxing, application of cosmetics, protection seals and labeling And so on.
In some cases, woodworking such as precutting, drilling and mortise cutting is performed.

As described above, according to the method of the present invention, since a plate material having an unfixed width is used as the primary lamina, a thinning material which has hardly been used in the past, a crushed tree, a lot of knots and bends, etc. are used. Since it becomes possible to effectively use high-quality logs and scraps generated during lumbering, it is not only extremely economical, but also extremely beneficial in terms of forestry promotion and forest conservation. Since the consumption of timber can be suppressed, it can contribute to the conservation of tropical rain forests.

Further, according to the present invention, since it is possible to consistently produce from receiving raw wood to shipping laminated wood by a series of automatic devices, distribution cost is not required.
We will be able to manufacture and supply laminated wood in response to demand,
Moreover, since the material is used in a certain size, it is possible to effectively use the part that has been discarded as a scrap material in the past.
The yield of the material, which was around%, can be almost doubled to around 55%, which significantly reduces the manufacturing cost. Furthermore, since the thickness of the primary lamina 2 is set to 5 to 30 mm, preferably 10 to 20 mm for drying, the time required for drying is shortened, not only the drying cost is greatly reduced, but also the drying is performed completely and uniformly. This eliminates the need for long-term seasoning, and cuts manufacturing costs significantly from these points.

Further, since the primary lamina 2 is completely dried, good adhesion can be achieved both in the width band and in the veneering, and high adhesive strength can be obtained. Also, since the width of the primary lamina 2 used is random, the uniformity of the material of the laminated wood, especially of the multilayer laminated wood is increased, and as a result, almost no cracking or deformation occurs during long-term use. No
We will be able to provide high quality laminated wood that does not change over time. Further, since the laminated material according to the present invention has a low water content and a uniform quality, it is possible to guarantee strength, water content, and other qualities that were impossible in the past.

Next, an apparatus for carrying out the above method of the present invention will be described. In FIGS. 2 and 3, 10 is a log supply device, 20 is a log cutting device, 30 is a primary lamina plate manufacturing device, 40 is a primary lamina drying device, 50 is a primary lamina finishing device, and 60 is a secondary lamina manufacturing device. , 70 is a tertiary lamina manufacturing device, 80 is a veneering device, 90 is a laminated lumber finishing device, and 100 is a product inspection device. The log supply device 10 carries out the log 1 from a barker (not shown) and supplies it to the log cutting device 20 in the subsequent stage.

The log cutting device 20 is a device for the above-mentioned first step, and is usually composed of a cutting device 21 such as a chainsaw and its auxiliary equipment, and the log 1 supplied from the log supplying device 10 is desired. The round material 1-1 having the dimensions of is cut and aligned. The size of the round bar 1-1 to be cut and aligned at this time is not particularly limited, but when manufacturing the single layer laminated wood 5, it is the same as or slightly longer than that, and when manufacturing the multilayer laminated wood 9, the raw wood 1 is It is recommended that the size be approximately equal. The preferred size is around 1.8 to 2 m.

The primary lamina original production apparatus 30 is an apparatus for the above-mentioned second step, and produces round material 1-1 to obtain an irregular plate material 1-2 and a material 1-3 having a rectangular cross section.

36, Heat treatment roller device for applying pressure and heat treatment to the primary lamina original plate 1-4 in order to improve the efficiency of the subsequent drying process 37
And a scrap material conveying path 38. As the first sawing machine 31, for example, a single band saw or a twin band saw is used, and as the suitable second sawing machine 32, for example, an upper and lower gang ripper and the like can be cited. Is recommended.

The features of this apparatus are that the raw wood is cut into an appropriate length and used, and that a saw band machine is used in combination with, for example, a twin band saw and an upper and lower gang clipper to minimize the cross-sectional area of the saw path. There is no restriction on the width of the primary lamina original plate 1-4, and therefore the degree of freedom in the sawing method in the first sawing machine 31 is high, and the generation of scraps can be minimized. Since the milling is performed with a certain size, it is always possible to obtain the widest primary lamina original plate 1-4 that can be obtained from a given material, and by these, the overall yield of the material is up to the maximum limit. To be raised. The center cut-sew 36 and the heat treatment roller 37 are optional components, not essential components, and are provided as needed. Thus, the primary lamina original plate 1-4 is obtained by the primary lamina original plate manufacturing apparatus 30.

The drying chamber 41 is a well-known wood drying device, which has a heat source, a temperature control device, a ventilation device, etc. inside, and is carried in by being stacked on the material carrier 42 through the bars 433 in layers. The primary lamina original plate 1-4 is dried. There are no particular restrictions on the drying method, and any of a hot air method, a steam method, a decompression method, etc. may be used. These are appropriately selected mainly depending on the properties of the material to be handled and the required processing capacity.

The constructions of the material carrier 42, the cross carrier 43, and the crossing device 45 are shown in FIG. Since the construction of the crosspiece collecting device 48 is similar to that of the crossing device 45, only the crossing device 45 will be described here. The carriage 43 is a chassis 431.

In that case, the hydraulic cylinder 453 operates to pull in the rod 454, and the transfer arm 455, the Y-shaped intake pipe 456, and the suction cup 457 are pulled up, so that the crosspiece 433 attracted to the suction cup 457 in each crosspiece magazine 432 is removed. It is raised all at once.

In that case, the rotating arm 452 is rotated and the crosspiece is rotated.
When 433 is moved above the material carrier 42, then the hydraulic cylinder 453 operates to extend the rod 454, and the bar 433 is lowered onto the primary lamina master plate 1-4 stacked on the material carrier 42. , The vacuum valve (not shown) is closed and the vacuum break valve (not shown) is opened at the same time, so that all the bars 433
Are separated from the suction cups 457 and aligned on the primary lamina master plates 1-4.

In that case, the hydraulic cylinder 453 is actuated and the rod 454 is retracted, and then the rotating arm 452 rotates above the beam carrier 43, and the next step of stacking is performed in the same manner as above. It is something that will be done. The structure of the crosspiece collecting device 48 is the same as that of the crossing device 45, and is different from the crossing device 45 in terms of operation as well except that the crosspiece 433 is returned from the material carrier 42 to the cross carrier 43. Since the operation of the crosspiece collecting device 48 will be already clear, the description thereof will be omitted.

The dried primary lamina original plates 1-4 are conveyed to the lamina unloader 47 mounted on the material carrier 42, where the bar 433 is collected by the bar collecting device 48 and unloading is performed. The front and back sides of the primary lamina original plate 1-4 are inspected, and the front and back sides are aligned and sent to the primary lamina finishing apparatus 50. Thus, in the present embodiment, the material carrier 42 and the rail carrier 43 are automobile vehicles that operate on the track, and their operation is the material carrier operating device 46 and the carrier carrier operating device, respectively. Performed according to 49.

However, for example, a forklift that is driven by a person, a dolly, or the like is also used as these transport vehicles, and a conveyor or a transport means that replaces them is also used.

A secondary lamina stocker 73, a secondary lamina selection device 74,
It is composed of a finger processing device 75, an adhesive applying device 76, a finger joining device 77, an accumulation conveyor 78 and the like. The upper and lower planar device 71 removes a slight step on the surface of the secondary lamina 4 due to the width stripping and an adhesive protruding to the surface to make the thickness of the secondary lamina 4 uniform. Numeral 72 is a shape cut of both sides and both sides of the secondary lamina 4.

An appropriate one is selected from the above and supplied to the finger processing device 75 in the subsequent stage. A finger joint is formed in the mouth of the secondary lamina 4 to be finger-joined by the finger processing device 73 using a known finger cutter. On the joint surface of the finger joint, an adhesive and a curing accelerator are applied by an adhesive application device 75, finger joining is performed by a finger joining device 76, and a tertiary lamina 7 having a desired length is formed. 7 is sent to the veneering device 80 in the subsequent stage.

As shown in FIG. 3, the veneering device 80 includes an adhesive applying device 81 and a tertiary lamina laminating device 8
2. Consists of a tertiary laminar laminated body conveying line 83, a chain composite press 84 and a tertiary lamina unloading port 85, which are provided on both sides of the tertiary lamina laminated body conveying line 83. An adhesive is uniformly applied or sprayed on the surface of the conveyed tertiary laminar 7 by an adhesive application device 81, and the tertiary laminar laminating device 82 stacks the adhesive until a predetermined thickness is reached. It is formed. This tertiary lamina laminate 8 is sent to the subsequent chain composite press 84 either alone or in a state of being stacked.

Details of the chain composite press 84 are shown in FIGS. 9, 10 and 11. FIG. 9 is a plan view of this chain compound press, FIG. 10 is a central sectional view thereof, and FIG. 11 is a partially cutaway front view thereof. It is necessary to press the long tertiary laminar laminated body 8 for several tens of minutes for peneering,
Moreover, the size and shape of the tertiary lamina laminate 8 are different. Therefore, if it is attempted to process this with a conventionally known press, it is necessary to provide a large number of large presses, which increases the facility cost and significantly reduces the efficiency when processing a small tertiary lamina laminate 8. In addition, there is a problem that usability becomes poor.

This chain compound press 84 was devised in order to solve such a problem, and fixed surface plates 841 provided on both sides of the conveying line 83 sandwiching it, and a large number of fixed surface plates 841 on the fixed surface plate 841. The fractionation press devices 842 are arranged, and each fractionation press device 842 is connected to the transport line 83.

The central control unit (not shown) makes a rational use plan of the chain composite press 84 in order to efficiently carry out the production plan, and the produced tertiary laminar laminate 8 has the same length. Accordingly, it is placed at a predetermined appropriate position and pressed by a plurality of corresponding fractionation press machines 8424. On each fixed surface plate 841, a large number of tertiary lamina laminates 8 having various lengths, widths and thicknesses can be reasonably combined and arranged and pressed with almost no space between them.
Since all the fractionating press machines 8424 are operated almost all the time, the operation efficiency is maintained at an extremely high level. or,
Since many tertiary laminar laminates 8 having the same shape can be stacked and pressed, the operation efficiency of the apparatus can be improved also in this respect.

Examples include polishing, painting, waxing, sticking of decorative materials, protective stickers and labels, and, in some cases,
Woodworking such as pre-cut processing, drilling, mortise cutting and grooving is performed.

It is desirable to perform a product inspection on the manufactured product. The product inspection device 100 is provided for such a purpose, and the inspection station 101
And a product shipping port 102. In the normal inspection station 101, it is customary to inspect the dimensions of each part, the presence or absence of defects such as scratches, and whether or not the specified finishing process is being performed reliably.

However, the laminated material according to the present invention has high quality stability and can guarantee the bending strength and the water content. To make these guarantees, inspection stations
In addition to the above-mentioned normal inspection equipment, the 100 is equipped with a measurement recording device for bending strength and moisture content, and inspects all products, or conducts appropriate sampling inspection for each lot of products. It is recommended that such data is printed on an appropriate label or the like together with the other inspection data described above and attached to the product, or directly printed or stamped on the product for display.

Since the laminated material manufacturing apparatus according to the present invention is constructed as described above, according to the present invention, the above-described method of the present invention can be reliably carried out. Incidentally, the configuration of the device of the present invention is not limited to the above embodiment, for example,
As the raw wood to be used, not only the thick logs as shown in the figure, but also large-sized scraps, etc. can be used, and in this case, a device for selecting and supplying those timbers corresponds to this. The cutting device is a device that cuts the supplied material into uniform lengths.

In addition, the primary lamina original sheet production apparatus is any combination of a lumbering machine and a woodworking machine as long as it is an apparatus capable of producing a plate material having a desired constant thickness and length and an arbitrary width from a given material. The primary lamina original plate drying device includes, for example, a solar natural drying facility. Furthermore, the design of the primary lamina finishing machine can be freely changed.
In short, it is sufficient if the primary lamina original plate produced by drying can be strained and finished into a flat plate with a rectangular section perfectly, and the secondary lamina manufacturing equipment also strips the shaped primary lamina. However, any device may be used as long as the secondary lamina can be obtained by cutting it into a certain length, and the tertiary lamina manufacturing apparatus is also one that obtains the tertiary lamina by vertically stripping the secondary lamina. It suffices to say that the finger joint described above includes not only the known acute-angled triangular finger joint, but also all the same zigzag joints, concave-convex joints, fitting joints, and the like.

In the above description, as the veneering step and the apparatus, the tertiary lamina is adhesively laminated to obtain a tertiary lamina laminate, and the tertiary lamina laminate is pressed to obtain a complete tertiary lamina laminate. When using a mold or instant adhesive type adhesive material, a tertiary lamina laminate is obtained by pressing each time one tertiary lamina is adhered, and further, in the above,
