Abstract

PURPOSE:To reduce the maintenance cost, decrease the number of workers and improve the efficiency of a process and the yield of veneers by a method wherein the supply of face veneers, rear veneers and core veneers and the process of making veneer laminates are incorporated into a single and common continuous process, and many square veneers to be used for the face veneer, rear veneer and core veneer are vertically seamed and laterally seamed by a butt joint method as a unit of a plurality of veneers to make the square veneers in continuous lengths and decrease their numbers. CONSTITUTION:Of square veneers 1, a group consisting of the square veneers 1a for parallel lamination is straight advanced in the direction of fiber, and a group consisting of the square veneers 1b for orthogonal lamination is changed in their direction at a right angle, thus the veneers are divided into the group of a unit of a plurality of the veneers to be delivered to the process at the following stage. At the next stage, the respective groups are vertically seamed and laterally seamed to form an elongated seamed-veneer 2a having lengthwise grain and an elongated seamed-veneer 2b having breadthwise grain, from which the regular sizes l1, l2 can be obtained. Then, the veneers 2a, 2b having the regular sizes l1, l2 are freely adjusted to cutting sizes of two kinds somewhat different from each other, respectively, and are simultaneously cut off at their fore and rear parts. An adhesive is applied to the veneers 2a, 2b produced in a series of the above-mentioned processes, and they are superimposed on one another in such a way of stepwise deviation and laminated, thereupon they are thermally pressed to make an intermediate product 3a or 3b in a continuous form.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention uses a rectangular veneer veneer whose lengths are approximately equal in the fiber direction and in the orthogonal direction to the raw material, and processes the whole layer in the fiber direction or in one layer. A method and apparatus for manufacturing a veneer laminate material, commonly known as LVL or LV8, which is a veneer laminate material formed by laminating and bonding in a step-like staggered butt joint with the fiber directions between the layers perpendicular to each other. It is related to.

(Prior Art) A method and an apparatus for manufacturing a veneer laminate using a rectangular veneer veneer whose fiber direction and orthogonal direction are approximately equal in length according to the prior art are disclosed, for example, in the applicant's earlier application. Continuous laminated material using rectangular veneer and manufacturing method thereof, and JP-A No. 62-189101
No. 62-189102 and Japanese Unexamined Patent Publication No. 189102/1989, a method for manufacturing continuous laminated materials using rectangular veneers, etc., states that `` rectangular veneers made into butt joints perpendicular to the fiber direction are used for the front and back plates,
Further, a method and apparatus for manufacturing a veneer laminate using the square veneer with scarf joints in the fiber direction as a core plate are disclosed. Similarly, in the veneer laminate material and its manufacturing method, etc., disclosed in Japanese Patent Application Laid-open No. 1-166901, which is the applicant's earlier application, ``square veneers with scarf joints in the fiber direction are used for the front and back plates, A method and apparatus for manufacturing a medium plate laminate using the square veneer made into a hat joint perpendicular to the fiber direction as a core plate is disclosed.

[Problem to be solved by the invention] According to the above-mentioned prior art, ``a rectangular medium plate made into a butt joint perpendicular to the fiber direction is used as the front and back plates, and the rectangular veneer is scarf-jointed in the fiber direction. ``Method and apparatus for manufacturing laminated veneer materials used for core plates'' requires the supply and conditioning processes of the top plate, back plate, and core plate to be performed in parallel multi-stage processes, which streamlines the process and requires less equipment. Not only was it expensive and inefficient as it required a large number of workers, but it also had the disadvantage that it lacked versatility in terms of product usage because only horizontally grained square veneers could be attached to the front and back plates. In addition, according to the prior art, ``veneer lamination using rectangular veneers with scarf joints in the fiber direction as the front and back plates, and using the square veneers with butt joints perpendicular to the fiber direction as the core. The veneer yield and work efficiency were extremely low, as the veneer production method and equipment required scarfing of both ends to prepare the top and back boards. Since all of the core plates are transferred as individual rectangular veneers to the assembly process near the final stage, the process speed of the high-speed transfer of individual rectangular veneers quickly reaches its limit, resulting in overall inefficiency. This resulted in a significant lack of productivity.

In order to eliminate the drawbacks of the above-mentioned prior art, the present invention aims to reduce the equipment costs and labor costs by forming all the steps of supplying the top plate, back plate, and core plate and adjusting the plate into a single common continuous process. By significantly reducing the number of square veneers used for the top plate, back plate, and core plate, the number of square veneers used for the top plate, back plate, and core plate is lengthened and reduced by vertically and horizontally splicing them into multiple butt joints. The aim is to dramatically improve process efficiency and veneer yield.

(Means for Solving the Problems) In order to achieve the above object, the method for manufacturing a veneer laminate of the present invention is comprised of the following series of steps a to c.

b) Vertical and horizontal splicing process The rectangular veneers for parallel lamination and rectangular veneers for orthogonal lamination, which are divided into groups of multiple sheets delivered from the previous process, are separated in a vertical direction so that the required standard dimensions can be collected. Vertical and horizontal splinting process in which long grained veneer and horizontal grained long spliced veneer are alternately vertically and horizontally spliced.

C) Standard-length double-cutting process A regular-length double-cutting process in which the long vertically grained veneer and the horizontally long peeled veneer, which were vertically and horizontally spliced in the previous step, are bisected into different standard sizes.

Furthermore, the apparatus for manufacturing a laminated veneer material of the present invention is comprised of a series of mechanisms d to q below.

A composite type veneer vertical and horizontal stripping machine equipped with attachments, a conveyor, and a braking member.

g) Double-cutting machine for veneer length and width Cutting the lengthwise and horizontally-split veneers vertically and horizontally into slightly different lengths. This is a veneer board cutter with a fixed length, which has a pair of front and rear cutting blades installed between the rows of the conveyor so that the cutting size can be adjusted freely.

[For production]

The method for producing a laminated veneer material of the present invention and the operation of its apparatus will be explained with reference to FIGS. Among the rectangular veneers 1 whose lengths are approximately equal in the i-fiber direction and the orthogonal direction, the group that will become the rectangular veneer 1a for parallel lamination is placed in the same wc direction as illustrated in Fig. 1. The fiber direction is changed at right angles to form a group of rectangular veneers 1b for orthogonal pasting, and the fiber direction is changed at right angles as shown in FIG. A transfer and conversion process is formed, which consists of a single-plate turntable with an elevating mechanism and a turning mechanism installed between the rows of conveyors, in order to divide the conveyor into groups and deliver them to the subsequent process. In addition, in the latter stage of the transfer and conversion process, the square veneers 1a for parallel lamination and the rectangular veneers 1b for orthogonal lamination, which have been delivered from the earlier process and have been divided into groups, are transferred to the required standard size. Normally, a bat with a length of about 4 pieces as shown in Figs. 1 and 2 is attached to the longitudinally grained long striped veneer 2a and the horizontally grained long striped veneer 2b from which the grains, e1, and f2 can be collected. A vertical and horizontal splicing process is formed using a composite veneer vertical and horizontal splicing machine that alternately vertically and horizontally splices the vertically grained long veneer 2a and the horizontally grained long veneer 2b of the joint. There is. The above-mentioned required standard dimensions 11 and 12 are the lengths for the long striped veneer 2a with vertical grain for parallel lamination and the long striped veneer 2b with horizontal grain for orthogonal lamination. On the other hand, usually the adhesive is applied to the surface of the long peeled veneers 2a, 2b to a standard size 111!2 commensurate with the length of each material from the time they are bonded under heat and pressure. That is, the standard size 1 of the long striped veneer 2a for parallel pasting with vertical grains in which the fiber direction is parallel to the longitudinal direction and there is almost no longitudinal extension by adhesive.
1, the standard size l2 of the long spliced veneer 2b for orthogonal pasting with a cross-grain that is perpendicular to the I-fiber direction or the longitudinal direction and has some elongation is slightly shorter than that, for example, 2 per unit length. ,
In order to adjust the mechanical error caused by elongation by cutting the material as short as 3 mm/m, a pair of cutting blades are installed between the rows of the conveyor at the front and rear in the conveyance direction, and one cutting blade is set at the front and rear in the conveyor direction. A device is installed so as to be slightly movable, and the standard size 11 in the case of the long peeled veneer 2a for parallel lamination and the standard size 12 in the case of the long peeled veneer 2b for orthogonal lamination are set respectively. It is configured to be adjustable to two slightly different cutting dimensions, and by cutting the front and back in two at once, the standard dimensions Jl1, J! A fixed-length double-cutting process is formed using a veneer fixed-length double-cutting machine configured to also function for stabilization.

Furthermore, the longitudinal grains produced in the series of processes consisting of the transfer conversion process for the square veneers 1a and 1b, the vertical and horizontal splicing processes and the standard-length bisecting process for the long splintered veneers 2a and 2b described above. The long striped veneer 2a for parallel lamination and the long striped veneer 2b for cross-grained orthogonal lamination are attached to their respective required surfaces, that is, the continuous intermediate product 3a illustrated in FIGS. 3 and 4.
An adhesive such as urea resin is applied to the top surface of the back plate B and the core plate C except for the top layer F of , 3b using a spreader, and this is adsorbed and transferred to the assembly location using a transfer robot or the like. For example, as shown in the figure, the sheets are stacked in a staggered manner so as to form a stepped hat point at a pitch P that is several tens of times the main board thickness. The structure at this time is composed of a long longitudinally grained veneer 2a as illustrated in Fig. 3, and all the fibers are pasted parallel to each other in the direction of the fibers or in the direction of the webbing, commonly known as LVL. Intermediate product 3a which is said to be
Or, as illustrated in Fig. 4, a long cross-grained veneer 2b is inserted into a part of the second layer on the front and back sides, and the part is pasted perpendicularly to the fiber direction or the longitudinal direction. After laminating the intermediate product 3b, commonly known as LVB, to the required number of plies, it is transferred to a high-frequency tack press for temporary bonding and a continuous hot press for final bonding, which are equipped in a hot press area. The product is heated and pressed to continuously produce continuous wide and long products, for example, several ctn thick and several meters long, and then delivered to the next subdivision process.

Accordingly, the present invention provides a transfer conversion process for the rectangular veneers 1a, 1b by equipping a veneer turntable, and a combined type veneer vertical and cross-splitting machine for the rectangular veneers 1a, 1b. The formation of vertical and horizontal splicing processes using equipment and the formation of a fixed-length double-cutting process using a single length double-cutting machine for the long splintered veneers 2a and 2b are methods for producing this type of veneer laminated material. And, for the first time, it has become possible to ``form all of the feeding and conditioning processes of the top plate F, lining plate B, and core plate C into a single common continuous process''. It is also the first time that ``a large number of rectangular veneers used for the top plate F, back plate B, and core plate C are lengthened and reduced in number by vertically and horizontally splitting them into multiple butt joints.'' It has become possible.

(Embodiment) To explain the embodiment of the present invention with reference to FIGS. 5 to 15, FIGS. 5 to 7 show a series of veneer plates including a transfer conversion process, a vertical stripping process, a horizontal stripping process, and a standard-length bisecting process. This is an example of a manufacturing process for laminated materials, in which a rectangular veneer 1 having approximately the same length in the fiber direction and in the orthogonal direction, for example, about 17'l'L angle, is mounted on the lifting table 24 and pinched from the fiber direction. The veneer feeder 4 equipped with rolls etc. is divided into groups of a plurality of veneers according to the order of assembly and then fed.

The veneer feeder 4 is connected to a veneer turntable 8 equipped with a conveyor 7.
Among the rectangular veneers 1 supplied to , rectangular veneer 1 for parallel lamination
The group that will become a will continue to be transported in the same direction as the fibers, and the group that will become the rectangular veneer 1b for orthogonal pasting will change its direction at right angles and continue to be transported in the direction orthogonal to the fiber direction. The veneer is transferred to a conveyor 26 equipped with a ruler member 25 disposed at the next stage, and then sent in groups of multiple veneers to a composite type veneer vertical and horizontal splicing machine 13 disposed at the next stage. supply this to. The rectangular veneers 1a for parallel lamination and the rectangular veneers 1b for orthogonal lamination, supplied to the veneer lengthwise and crosswise splicing machine 13, are separated by the vertical grain length by the veneer lengthwise and crosswise splicing machine 13. After being alternately vertically and horizontally spliced into shaku-splitting veneer 2a and cross-grained long-splitting veneer 2b, they are transferred onto the next stage conveyor 15, and installed in front and behind the conveyor 15 so that the cutting dimensions can be adjusted freely. The veneer is once stopped directly under the veneer standard-length double-cutting machine 16 equipped with a pair of cutting blades 14a, 14b, and the vertical and horizontal grains of the long veneer 2a, 2b are cut by the veneer regular-length double-cutting machine 16. It is divided into two types of standard sizes, f21.12, set depending on the direction, and then bisected. Two types of fixed length dimensions, fl'1. The long peeled veneers 2a and 2b, which have been divided into sections f2 and bisected, are further transported and carried into a spreader 27, such as an airless spray device for applying adhesive, disposed at the next stage. After the adhesive is applied to the required surfaces of the long peeled veneers 2a and 2b by the spreader 27, they are delivered onto a relay conveyor 17 provided for preparation of the structure and are temporarily stopped. The long peeled veneers 2a and 2b, once stationary on the relay conveyor 17, are provided with photoelectric sensors in front and on the sides of the conveyor 17, respectively, so as to be able to detect shifts in transport in the longitudinal direction and the width direction. Single plate position detector 18 consisting of etc.
a, 18b. 18C, and also connects it to the computer 20 of the transfer robot 19 so that it can be used before and after the process of transferring the long peeled veneers 2a and 2b from the relay location to the assembly location by the transfer robot 19. Then, after correcting the deviation of the left and right transfers, the medium-sized products 3a and 3b are stacked in a staggered butt joint on the assembly conveyor 28 placed at the assembly location according to the assembly order. Continuous intermediate products 3a, 3 assembled on the assembly conveyor 28
Waiting for the completion of the assembly work for one batch, it is transferred to the next high-frequency tack press 22 equipped with a high-frequency oscillation I129, where it is temporarily bonded in a lattice shape, and then steam or the like is used as a heat source in the next transfer cycle. The product is transferred to a continuous hot press 30 and bonded with heat and pressure on the entire surface to form a continuous wide and long product 31, which is cut into appropriate lengths by a cut saw 32 and stacked by a stacker 33 for the next step of dividing into small pieces. It is to be handed over.

Next, FIGS. 8 and 9 show details of the single-plate turntable 8 disposed in the above-mentioned transfer and conversion process, and between the rows of the conveyor 7 that shares rollers and belts. Gastric unloader m consisting of a pair of upper and lower air cylinders, etc.
5a, 5b, and one side of the elevator side 5a, 5b, in this case a rotating mechanism 6 consisting of an air cylinder or the like mounted on the lower lifting mechanism 5a.
When the rectangular veneer 1 for parallel pasting arrives, the veneer turntable 8, which is composed of a pair of upper and lower discs 34a, 34b, etc., mounted on a shaft on a shaft is not activated, and is transferred only by the conveyor 7. Furthermore, when a rectangular veneer 1 for orthogonal pasting arrives, it is activated, rotated 90'' each time, and placed on the conveyor 7 again to continue its conveyance.

In addition, Figures 10 and 11 show a composite veneer vertical and horizontal splinter 1ll13 installed in the vertical and horizontal splicing process described above.
This is an example of the details of the rectangular veneer 1a for parallel lamination and the rectangular veneer 1b for orthogonal lamination, which are divided into groups of multiple veneers, each having the required standard size 111!2.
In order to vertically and horizontally strip the veneer into vertically grained long veneers 2a and horizontally grained long veneers 2b that can be harvested, the veneer is conveyed directly below the cutting blade 9 by a conveyor 11a such as a belt facing vertically. Both ends of the rectangular plate 1a whose fiber direction is parallel to the transfer direction and both end surfaces of the rectangular intermediate plate 1b whose fiber direction is perpendicular to the transfer direction are separated into groups of multiple sheets to be transferred, with respect to the transfer direction. A veneer detector 35 consisting of a photoelectric switch or the like installed in a line orthogonal to each other detects the length of the veneer, and the cutting blade 9 cuts the uneven portions of both ends and end faces of the veneer for precise splicing. After preparing the plates so that they can be joined together, the plates are sandwiched by a 1-lb conveyor such as a belt that faces each other vertically during the transfer process, and adhesive is applied to the required leading end face each time using a glue applicator 10 made of hot melt resin or the like. A rail bar or the like is pushed onto the braking members 12 facing each other vertically, and the long veneers 2a and 2b with the vertical grain and the horizontal grain are alternately vertically and horizontally ripped using the same device.

Next, FIGS. 12 and 13 illustrate the details of the veneer standard-length double-cutting wi 16 installed in the aforementioned standard-length double-cutting process, which stabilizes the cutting dimensions to avoid structural errors. For this purpose, a pair of front and rear cutting blades 14a, 14b are installed between the rows of the conveyor 15 such as a belt so that the front and rear can be cut at once. One side of the veneer 14b is designed to be slightly movable back and forth, and the long veneer 2b for cross-grained orthogonal gluing, which is to be spliced in the longitudinal direction perpendicular to the m1 direction, is attached to a long piece for parallel gluing with vertical grains. By cutting the shakuhagi veneer 2a to a standard size 12 that is slightly shorter than the standard size 11, only the long splinter veneer 2b for cross-grain orthogonal pasting extends in the longitudinal direction after applying adhesive. This is designed to eliminate situations where errors occur.

Furthermore, FIG. 14 shows the transfer robot 1 when transferring the long peeled veneers 2a, 2b from the relay location at the front stage to the assembly location at the rear stage.
The long stripping veneers 2a, 2b are attached to the suction rack 21 attached to the
This is an example of the suction mode when suctioning the intermediate products 3a and 3b.Since the suction blade 21 is formed in a gentle arc shape in the longitudinal direction, it arrives directly above the intermediate products 3a and 3b and starts the transfer operation. The previous suction mode creates a gap S by an amount corresponding to the curved shape of the fixed length 11.12 of the assembled long peeled veneers 2a and 2b that are already placed flat as shown in the figure. Therefore, its apparent plane dimension is e1
-28. i2-23, so if there is a slight transfer error during the butt joint mechanism, the mutual end faces will collide and the products will overlap, or the transfer error will gradually be pushed backwards and the product will be accumulated. This is to eliminate situations in which the normal mechanical position is disturbed due to Note that 36 in the figure is a pipe that connects the suction canister 21 to an exhaust blower or the like.

Furthermore, FIG. 15 shows an example of divided feeding of high-frequency power to the grid electrodes 23a and 23b installed in the high-frequency tack press 22, which avoids heating spots due to standing waves that tend to occur in the length direction. In order to do this, the application distance 13 in the longitudinal direction with the same electrode is kept within the permissible range of heating spots, and is usually kept to a heating spot of about 20% or less, which almost achieves the purpose of temporary adhesion and does not cause actual damage such as peeling phenomenon. In order to set the divided feed voltage with an application distance 13 up to about 2 m, for example, the long stripped veneer 2a, 2b standard dimensions f1, 1
The grid electrode 23a of the high frequency tack press 22 is 2 or 4 m&deg. In the case of 23b, as shown in the figure, it is divided into a plurality of groups, in this case two groups, each with a different circuit, for example, high frequency power is applied simultaneously to both groups by high frequency oscillation II 29 of a push-pull circuit, or High frequency power is applied alternately by a high frequency oscillator.
The application distance i3 in the longitudinal direction using the same electrode is limited to within the allowable range for heating spots. In addition, 37a and 37b in the figure are the grid electrodes 23a. 23b is an insulator holding it, 38 is a fixed platen of the high frequency tack press 22, 39 is a movable platen, and 40 is a hydraulic cylinder.

(Effects of the Invention) As explained above, the present invention has the following advantages: It is constructed so that it can function as ``to lengthen and reduce the number of square veneers used for the back plate and core plate by vertically and horizontally splitting them into multiple butt joints.'' The present invention eliminates all the drawbacks of the conventional technology and is economical, making it possible to ``significantly reduce maintenance costs and labor costs, and dramatically improve process efficiency and veneer yield.'' This invention is extremely effective in its implementation.
