The adhesives are laminated together by hot pressing, in such a manner that a multi-layered board of continuous length of glued wood is produced. The wood chips in each layer of the resulting glued wood board are mounted in a staggered relationship with the wood chips in the adjacent layers in the length direction of the board. The present invention also relates to a device for manufacturing the rubber-clamped wood. [Prior Art]
爲使較佳地了解本發明之背景，首先參照圖1，其槪 略地顯示一用以製造疊層合板木材（LVL )的習知技術設 備，LVL即爲一典型之膠夾木材，其中，多數之合板片以 交錯方式被疊層在一起，且每一合板片之木紋主要沿著所 產生之製品或LVL板的長度運行。In order to better understand the background of the present invention, reference is first made to Figure 1, which schematically shows a conventional technical device for manufacturing laminated laminated wood (LVL), which is a typical rubber-clamped wood, wherein Most of the plywood sheets are laminated together in a staggered manner, and the wood grain of each plywood sheet runs primarily along the length of the resulting article or LVL panel.
該設備包含被安排在三不同階段處的三組熱壓機X、 Y與Z，沿著以圖式中右手側處之箭頭所示的加工中之LVL 板被運送的方向，以一間隔相互隔開。每一熱壓機X、Y 與Z具有一對被以一個在另一個上方裝設的可移動上部與 下部加熱板XI、Y 1與Z 1。爲便於說明本設備，此三組熱 壓機X、Y與Z將個別稱之爲第一、第二與第三熱壓機。雖 然在圖式中未特別地顯示，提供三組與個別熱壓機X、Y 1276523 (2) 與Z結合之合板片進給器，且每一組均包含由指示進給方 向之箭頭所示的上部與下部可移動合板片進給器。在圖式 中，參考符號A、B、C代表木材合板片，每一具有實質上 相同之長度、寬度與厚度，且以其之木紋實質上相互平行 延伸，即爲沿著加工中之LV L板的長度方向延伸，而被以 相同定向裝設。必須注意，爲便於顯示，每一合板片之厚 度相對於其之長度係被顯示爲誇張地大，且用以移動加工 中之板的違送器係被省略。 在以圖1之設備製造LV L板中，首先，預備一對以陰 影線顯示合板片A，該合板片A的任一表面被以熱固性黏 膠塗覆。這些合板片A均由供第一熱壓機X用的第一進給 器所進給，且以置於二合板片A的配接表面之間的黏膠塗 覆表面組合在一起，如圖所示，以其之木紋沿著將被製造 之LVL板的長度延伸之定向，其之末端係爲偏位或交錯關 係。因而被一個置於另一個上方地放置之該二合板片A ’ 被運送至第一加熱板X 1之間的第一壓擠站，於此，合板 片A經由熱壓機X的熱與壓力而被膠黏在一起。在第一熱 壓擠作業完戊且加熱板X 1縮回之後，疊層合板片A被運送 朝向第二熱壓機Y處的第二壓擠站。 在前往第二壓擠站途中，即爲，在第一與第二壓擠站 之間的合適位置處’另一對以陰影線顯示之合板片B被第 二合板片進給器所進給’每一合板片B之鄰近於被疊層合 板片A的一表面上被覆塗黏膠，如圖所示，合板片B以與 合板片A成爲交錯關係之方式被置於先前疊層合板片A的 (3) 1276523 相對外部表面上。因而被置於合板片A上之合板片B均一 起被運送至第二壓擠站，於此，合板片B被第二熱壓機γ 所壓擠，以使被黏合至疊層合板片Α。 在完成第二熱壓機Y的壓擠之後，疊層合板片A與B均 被運送朝向第三壓擠站處之第三熱壓機。在第二與第三壓 擠站之間的合適位置處，再另一對以陰影顯示之合板片c 被第三合板片進給器所進給，每一合板片C的內部表面被 塗覆黏膠，且以交錯配置被置於合板片B的相對外部表面 上。因而被置於合板片A與B上之合板片C均一起被運送至 第三壓擠站，於此，由第三熱壓機Z類似地壓擠。因而， 形成疊層合板片A、B與C之組件。 包含前述合板片進給、置放、熱壓縮及運送之作業步 驟均於個別位置與工作站處依次地執行，因而形成經由其 之厚度計數的六層L V L板。如示於圖1，在每一層中之任 何二鄰近合板片A、B或C的末端均被互相緊密地鄰接以形 成端接頭，且合板片A、B與C均被置放使得端接頭均被以 規則交錯配置分佈在所產生之LVL板中。 爲使成爲地以所需黏合強度膠黏合板片，熱與壓力應 儘可能均勻地施加至將被黏合之每一合板片的整體表面。 但，在依據圖1所示之方法中，經由熱壓擠黏合一對合板 片A、B或C時，部份的成對合板片之表面不能直接承受熱 壓機的加熱板之壓擠動作。即爲，合板片A、B與C鄰近於 以運送方向觀看係上游末端部位之由R代表的區域，不能 被熱壓機之加熱板直接地壓擠，雖然某些熱會被傳導至合 -7- 1276523 (4) 板片的該區域。其結果，合板片的上游末端部位不能被以 所需強度黏度，因而影響產生之LVL板的品質。 如果爲使嚐試排除前述缺點而將在該一交錯陣列中的 合板片之區域R狹窄化或減少，在LVL板的任何二鄰近層 中的端接頭會被互相更接近地裝設，因而造成該板在抵拒 彎折時較弱。 因而，本發明之目的係提供製造諸如LVL的膠夾木材 之設備與方法，其可解決前述之問題。 【發明內容】 依據本發明，提供鄰近於一熱壓機之加熱板的一末端 之輔助加熱板。本發明使用輔助加熱板，可在使用多數之 諸如合板片的木材片製造諸如疊層合板木材（LV L )的膠 夾木材中，可壓擠一木材片的整體表面區域。 由下述之依據本發明之較佳實施例的說明，習於本技 藝者可更淸楚本發明之特色與優點，該說明係參照所附圖 式完成。 【實施方式】 參照圖2至1 1，將於下說明依據本發明的製造做爲膠 夾木材之疊層合板木材（LVL )的設備之較佳實施例。 必須注意，所有使用在本實施例中之合板片均已被妥 適地乾燥且實質上具有相同尺寸，即爲，大約4 mm之厚 度，沿著合板片之一般木紋（wood grain )定向所測量之 -8 -

Each of the hot presses X, Y and Z has a pair of movable upper and lower heating plates XI, Y 1 and Z 1 which are mounted one above the other. For convenience of explanation of the apparatus, the three sets of hot presses X, Y and Z will be referred to individually as first, second and third hot presses. Although not specifically shown in the drawings, three sets of plate feeders combined with individual hot presses X, Y 1276523 (2) and Z are provided, and each set contains an arrow indicated by the direction of the feed. The upper and lower movable plywood feeders. In the drawings, reference symbols A, B, and C represent wood plywood sheets, each having substantially the same length, width, and thickness, and the wood grain extending substantially parallel to each other, that is, along the processing LV The L-plates extend in the length direction and are mounted in the same orientation. It must be noted that, for ease of display, the thickness of each plywood is shown to be exaggerated relative to its length, and the dissidents used to move the in-process plate are omitted. In the manufacture of the LV L plate by the apparatus of Fig. 1, first, a pair of hatching sheets A are shown in a shaded line, and any surface of the ply sheet A is coated with a thermosetting adhesive. These ply sheets A are fed by a first feeder for the first hot press X, and are combined with a glue coated surface placed between the mating surfaces of the plywood sheets A, as shown in the figure. As shown, the orientation of the wood grain along which the length of the LVL sheet to be fabricated extends is offset or staggered. Thus, the plywood sheet A' placed one above the other is transported to the first crushing station between the first heating plates X1, where the heat and pressure of the plywood sheet A via the hot press X And they are glued together. After the first hot pressing operation is completed and the heating plate X 1 is retracted, the laminated sheet A is conveyed toward the second pressing station at the second hot press Y. On the way to the second crushing station, that is, at the appropriate position between the first and second crushing stations, 'the other pair of hatched sheets B are fed by the second plywood feeder 'A surface of each of the plywood sheets B adjacent to the laminated plywood sheet A is coated with an adhesive. As shown, the plywood sheets B are placed in a previously interlaced manner with the plywood sheets A. A (3) 1276523 is on the opposite outer surface. Thus, the ply sheets B placed on the plywood sheets A are all transported together to the second crushing station, where the plywood sheets B are pressed by the second hot press γ so as to be bonded to the laminated ply sheets. . After the completion of the pressing of the second hot press Y, the laminated ply sheets A and B are both transported toward the third hot press at the third crushing station. At a suitable position between the second and third crushing stations, another pair of shaded plywood sheets c are fed by the third plywood feeder, the inner surface of each plywood C being coated The glue is placed on the opposite outer surface of the plywood sheet B in a staggered configuration. Thus, the ply sheets C placed on the ply sheets A and B are transported together to the third crushing station, where they are similarly pressed by the third hot press Z. Thus, the components of the laminated ply sheets A, B and C are formed. The steps of feeding, placing, thermally compressing, and transporting the aforementioned plywood are sequentially performed at individual locations and at the workstation, thereby forming a six-layer L-L panel that is counted by its thickness. As shown in Figure 1, the ends of any two adjacent ply sheets A, B or C in each layer are closely adjacent to each other to form an end fitting, and the plywood sheets A, B and C are placed such that the end fittings are Distributed in a regular staggered configuration in the resulting LVL board. In order to bond the sheet to the desired bond strength, heat and pressure should be applied as evenly as possible to the entire surface of each ply sheet to be bonded. However, in the method according to FIG. 1, when the pair of plywood sheets A, B or C are bonded by hot pressing, the surface of the partial plywood sheets cannot directly withstand the pressing action of the hot plate of the hot press. . That is, the plywood sheets A, B, and C are adjacent to the region represented by R in the upstream end portion of the system in the transport direction, and cannot be directly pressed by the hot plate of the hot press, although some heat is conducted to the junction - 7- 1276523 (4) This area of the plate. As a result, the upstream end portion of the plywood sheet cannot be adhered to the desired strength, thereby affecting the quality of the produced LVL sheet. If the region R of the plywood in the staggered array is narrowed or reduced in an attempt to eliminate the aforementioned disadvantages, the end fittings in any two adjacent layers of the LVL panel are placed closer to each other, thus causing the The board is weaker when it resists bending. Accordingly, it is an object of the present invention to provide an apparatus and method for manufacturing a wood-clip wood such as LVL which solves the aforementioned problems. SUMMARY OF THE INVENTION In accordance with the present invention, an auxiliary heating plate adjacent one end of a heating plate of a heat press is provided.

As will be described in detail later, as shown by the arrows at the top of Fig. 2, the plywood sheets are generally moved to the right or transported from the peg sheet feed station 3 along the transport rollers 29, 73. The apparatus further includes a control unit C that receives detection signals from a plurality of sensors and rotary encoders and generates command signals to control individual actuators such as cylinders, actuators such as motors, and other devices The homework will be detailed later. A stack of ply pieces 5 is provided in the plywood feed station 3, and when viewed in the drawings of Figures 2 and 3, the wood grain of each plywood 5 in the stack generally extends in the transverse direction, 2 It can be seen that the wood grain case of the uppermost plywood in the pile of plywood pieces. Although not shown in the drawings, the stack of sheets 5 is supported by any suitable lifter that can be operated to set the stack of sheets such that the uppermost panel is often maintained at the same height. To achieve this goal, a suitable sensor (not shown) for detecting the height of the stack of sheets is provided. A suction head 6 is provided above the stack of sheets 5 for taking out the sheet 5 at a time from the stacked sheets. As shown in Figure 4, the suction head 6 includes an elongate hollow box 9 that is mounted to extend across the width of the plywood sheet 5, with a plurality of suctions 7 being arranged along the extension of the box 9, and each being held by a holder 8 fixed to box 9.

A threaded hole (not shown) is formed in the top surface of the upper heating plate 5 5 for receiving the screws 1 57 7 and 159 9 individually. The screw 1 5 7 is operatively coupled to a servo motor 6 6 assembled to a support block 160, the support block 160 is fixed to the frame of the apparatus, and the other screw 159 is freely rotatably assembled To the support block] 6 0. The screw 1 5 7 , 1 5 9 has a sprocket (not shown) connected by the endless chain 163, so that the rotation of the screw 157 driven by the servo motor 1 6 I -17-1276523 (14) It is transferred to the screw 丨5 9, and the two screws 〖5 7 and 159 are all rotated in a synchronized manner. Servo motor! 6丨 has a rotary encoder 1 64 which calculates the angle of rotation of the servo motor 16 6 to thereby determine the current position of the upper heating plate 15 5 relative to the reference position of the aforementioned reference suction head 8 7 and to make it controllably Position the upper heating plate. The upper heating plate 155 has a pair of hydraulic cylinders 166, the rods of which are connected to the heating plate 155 for holding the desired position of the heating plate 155 as will be detailed later. Each of the hydraulic cylinders 169 has a fluid orifice 169a that is connected to the oil reservoir 172 via a solenoid valve 17]. The valve 71 is normally open to allow the upper heating plate 5 5 to move up and down, but is kept closed when the heating plate 5 5 is held at the desired position. The first and second auxiliary upper heating plates 1 73, 177, as shown in Fig. 8, are provided on the left hand side of the upper heating plate 155 or on the side adjacent to the loading station 1 〇 1 . The shape, size and heating of these auxiliary heating plates 1 7 3, 17 7 are similar to those of the auxiliary heating plates 1 4 7 and 1 51 for the lower heating plates 1 4 3 . The upper auxiliary heating plates 1 7 3, 17 7 are each vertically moved by the cylinders 1 7 5, 7 7 individually between the retracted inoperative position and the lowered operating position as shown in Fig. 8 (only for each auxiliary) A cylinder for heating plates). The bottom surfaces of the first and second auxiliary upper heating plates 73,] 77 in the retracted position are placed substantially flush with the bottom surface of the upper heating plate 155. The first auxiliary heating plate 173 is lowered by the cylinder 175 by a distance of about 4 mm, that is, the distance corresponding to the thickness of the plywood, and the cylinder 179 is lowered by the distance of the second auxiliary heating plate 1 7 7 by about 8 mm. Corresponding to the distance of the thickness of the plywood sheet twice -18 - 1276523 (15) As shown in Fig. 2, the aforementioned upper and lower heating plates 1 5 5, 1 4 3 and the auxiliary heating plate 1 7 3, 1 7 7 and 1 4 7 and 1 5 1 are all installed in the range between the pair of guiding members 105. In the aforementioned apparatus, both the sensor and the rotary encoder are operable to generate a detection signal or a rotation angle count signal to the control unit C, and the control unit C reacts the signal to generate a plurality of command signals to control the device such as the motor 'cylinder And the operation of most drives and actuators of other devices (including those motors and cylinders not shown in the figure). As described above, the rotary encoders 9 5, 9 5 and 6 5 connected to the motors 9 3, 9 3 / and 6 1 can be operated to determine the suction heads 8 7 , 8 7 / and the upper heating The board 1 5 5 is associated with an individual current position of a predetermined reference position. In the illustrated embodiment, the reference position is established at any suitable location in the base material 1 placed on the chain conveyor 1 29, such as a base material 1 that traverses the length of the tape. The intermediate position is the position between the fourth and fifth laminate sheets of the base material 1, and the information of the reference position is stored in a suitable memory of the control unit c. In the manufacture of laminated plywood (LVL) using the aforementioned apparatus, the initial base material 1 in the form of a laminated ply assembly as shown in Fig. 11 is prepared in advance, and one end is formed from the end of the initial basic material 1. Continuous length LVL board. The initial base material 1 is made of a plurality of ply sheets, each of which has a thickness of about 4 mm and which is flattened and glued together by the adhesive. The wood grain of all the plywood sheets installed in the basic material, S is extended in the lateral direction when viewed in the drawing. It can be seen from the figure π that the 'initial basic material' is an eight-layer configuration with an eight-layer ply piece containing the first ply piece to the eighth ply piece starting from the bottommost ply-19- 1276523 (16) piece. . The plywood sheets in the base material 1 are all laid flat in a regular staggered configuration such that the ends of the plywood sheets of any two adjacent layers are separated by a length of about 1 20 mm 'except in the fifth and sixth plywood sheets. The end portion of the base material 1 is formed into a stepped ladder form, which is a step ladder formed by the fifth to eighth ply sheets and facing upward, and is first by r 7 0 mm. Other step ladders formed by the fifth plywood sheet and facing downward. Specifically, the initial base material I has a first end face 1 a, a second end face 1C, a second end face ie, a fourth end face ig, a fifth end face li, a sixth end face] k, a seventh end face] η ' and an eighth End face 1 t, each end face having a size of about 4 mm (corresponding to the thickness of the plywood piece) as measured vertically in the figure, and having a further first face la, second face Id, third face If, The fourth side lh, the sixth side im, and the seventh side ls, each of the above-mentioned faces is about 120 mm when measured along the grain direction of the plywood, and the fifth side lj is measured in the same direction. It has a size of approximately 170 mm. Referring to Figures 1 2 to 3, a method of manufacturing laminated wood (LVL) as a rubber-clamped wood by using the foregoing apparatus will be described below. The initial base material 1 is placed in advance on the chain conveyor 丨 29. The pair of feed rollers 1 1 , the pair of glue roller 17 and the glue amount control roller 19, and the fixed roller 23 are both activated and kept rotated in the direction of the individual arrows. The use of the initial base material 1 in this apparatus for the manufacture of LV L panels begins with the supply of a laminate of a fifth layer which does not require the application of an adhesive and which will be arranged in a LVL sheet to be manufactured. To this end, as shown in Fig. 2 (a), the applicator roller 17 is placed in its retracted inoperative position away from the fixed roller 23. -20- 1276523 (17) When the control unit C receives a start signal, it generates the first transport roller 2 9 to rotate in the direction of the arrow, and at the same time 4 1 / thus moves the stop plate 3 9 / to it In the extended position, ]2 ( 〇. At the same time, the suction head 6 is operated as shown in Figure 1 2 (a arrow direction, and the uppermost part of the self-stacked sheet is taken A 5 / and then in the direction of the arrow (or The right direction of the figure) Allows the plate A5 <The leading end is fed by the first roller and the first one and then forwarded as shown in Fig. 12 (b). When the A 5 / the leading end is captured by the lepton 1 1 , the attraction head 6 is no longer moved by the splicing plate A 5 / moving through the fixed lep 2 3 to the position detected by the previous detector 3], sensing The unit 3 1 generates a detection unit C, and the control unit C then transmits a signal to stop the first 2 9, as shown in Fig. 12 (c). The same signal causes the attraction head 6 to move back to its original preparatory position, as shown in Figure 12 (c). A further signal generated by the control I after a predetermined length of time that the transport roller 29 is stopped, the centering plates 3 3, 3 5 are all motivated to move until they both contact the lateral opposite sides of the plywood A5 / As shown in Figure 1 2 (d) 'Plywood A 5 is straightened and centered by the relevant transport path. After priming a length of the centering plates 3 3, 35, the centering plates 3 3, 3 5 are moved away from each other to a position which is sufficiently long 'to make the ply pieces properly and simultaneously, transporting the rolls 29 are rotated again to move forward 〗 〖 As shown in Fig. 3 (a) 'on the plywood A 5 / one of the signals arriving to drive the cylinder as shown in the figure, the double plate moves to transport light 2 9 When the plywood is spurred. When the guide end is sensed until the direction of the arrow of the control conveyance roller is reflected from the J-th unit C toward the edge, it is retracted to the center of the plywood for a predetermined time, and the K-plate A5 ^ leading end is 21 - 1276523 (18 When the sensor 3 7 / detected position, after a fixed length of time detected by the sensor 37, the control unit C provides a signal to cause the transport 29 to stop, which is sufficiently long ' The leading end is brought into contact with the stop plate. The cylinder 4 1 / is operated to move the stop plate 3 9 / to its contraction. Thereafter, the control unit C provides a signal to operate the cylinder 4 5 / , lowers the suction head 4 3 / to swing the plywood A 5 , and then at the preparation point the suction head 43 and the ply piece A 5 ' as shown in FIG. 13 (b) At the same time as the suction head 4 3 /, the cylinder 4 1 is operated such that the movement stops 39 to its extended operation position, and the suction bow at the plywood feed station 3 is operated to self-stack the sheets The uppermost plywood sheet A 5 is taken out, and 13 (b) is also shown. Then, the conveying roller 29 is again urged and the suction head 6 is moved to abutment A 5 between the feeding rollers 1 1 as shown in Fig. 13 (c). The second sheet A5 is moved forward in the same manner as the plywood sheet A5>. When the lead is detected by the sensor 31 before the A5, the control unit C reacts with the detection signal of the undetector 31, generating a retracted position that causes the transport roller 29 to stop and move the head 6 back thereto. The signal is shown in Figure 13 (d). In the same manner as the plywood sheet A 5 /, the centering plates 3 3, 3 5 are operated and the centering plywood A5 is fixed. After a predetermined length of time, the centering plates 35 are moved away from each other to their retracted positions, and at the same time the 'movers 2' are rotated again to move the ply sheets A5 forward. As shown in Fig. 14 (a), when the plywood sheet A 5 reaches the position detected by the end detector 37, after a predetermined length of time, the carrier 29 is stopped before the plywood A 5 The guide end and the stop plate 3 9 / joint - pre-roller 39 ^ return position so that the position 〇 and the moving plate I head 6 are self-inductively attracted to the sheet of the sheet plate to straighten 33 > the feeding roller is touched by the roller . -22- 1276523 (19) The cylinder 4 1 is pulsed such that the moving stop plate 39 to its retracted cylinder 45 is operated such that the suction head 43 is lowered to take out the ply and then raise the suction head 43 and the plywood, such as 1 (b) Cylinder 4 9 / is operated such that the movement of the stop plate 4 7 / to the extension thereof, the cylinder 2 1 (shown in Figure 2) is operated such that the lowering roller 19 to the glue application position, As shown in Figure 14 (b). The attraction head 6 is ejected from the third ply piece A4 / and the first conveyance roller 29 is rotated. A4 / through the feed roller] 1 and then through the rubber roller 丨 7 and between, as shown in Figure 14 (c), so that the plywood sheet A 4 / is on its upper surface. It has been coated with an adhesive on the upper surface and will be referred to as ''coated plywood sheet 后). After the splicing sheet A4 is fed to the roller 1 1 , the suction head 6 is returned to its original preparation in Fig. 14 (d). When the plywood sheet A 4 / is reached at the position where the leading end is sensed, the conveying roller 29 is stopped and the centering plate 3 3 is used to straighten and center the plywood sheet A4 / . At a predetermined length, the centering plates 3 3, 3 5 are moved away from each other to their retracted {ground, and the conveying roller 29 is rotated again to further move the gravity A4 ". At the leading end of the coated plywood sheet A 4 / is received by the sensor 37, at a section for the leading end to be brought to the contact stop plate 47, the transport roller 29 is stopped, as shown in Fig. 15 ( a). In the state of ^, the coated plywood sheet A4/series is located at the downstream offset position of the plywood sheet A5 (or to the right as shown in the drawing. Then, the sheet A5, and then the 'air position, And the same sub-assembly 17' operation makes the splicing plate fixing roller 2 3 with the adhesive coating surface of the splicing plate / has passed the position, such as the detector 3 1 is detected, 3 5 are all after the operation time, and at the same time plywood After the film/detected time is set, the value of -23- 1276523 (20) is corresponding to the first and second stop plates 3 9 〃 and 4 7 / The separation distance between them is about 1 20 mm. After the coated plywood A 5 / has been positioned by the stop plate 4 7 /, the stop plate 4 7 / is retracted as shown in Figure 15 (b). The motor for the second ply traverse device 5 5 / is operated to move the lift bar 5 1 / until its block 5 ] a — is detected by the sensor 5 8 / as shown in the figure ]5 (c). Thus, the coated plywood sheet A 4 / is offset in the plywood sheet A5 / underside, and the adjacent ends of the plywood sheet A4 / ' A5 / are staggered at a distance of about 20 mm as described above, as shown in FIG. (b). The cylinder 49 is operated to extend the stop plate 47 to its operational position. Thereafter, the suction head 43 is inactive by closing the shutter (not shown) so that the coated panel A5 / and the panel A4 / the rod 51 / are supported. Thereafter, by operating the first transport roller 29 and the suction head 6, the fourth plywood A4 is taken out, coated with an adhesive and transported forward in the same manner as the plywood A4/, as shown in Fig. 16 ( a) until its previous leading end is detected by the sensor 31. After the movement of the plywood piece A4 is stopped, the suction head 6 is retracted and the plywood piece A4 is centered by the centering plates 3 3, 3 5 as shown in Fig. 16 (b), after which the first conveying roller is again actuated. 29. When the leading end of the coated plywood A4 moved by the transport roller 29 is detected by the sensor 37, the contact end contact is stopped before the sensor 37 detects the subsequent segment for applying the plywood A4. After a predetermined time of the plate 47, the transport rollers 29 are all stopped, as shown in Fig. 17 (a). The leading end is placed in contact with the coated panel A4 of the stopper plate 47, at a position below the panel A5, and corresponding to the distance between the first and second stoppers 3 9 and 47 Approximately 1 20 mm is offset downstream. Then, the cylinder 49 is operated such that -24 - 1276523 (21) retracts the stopper plate 4 7, as shown in Fig. 17 (b). Then, the motors 5 5, 5 5 / are all operated simultaneously so that the lift rods 51 , 5 1 / are lowered until the sensors 5 8 , 5 8 — no longer detect the blocks 5 1 a, 5 I a ' As shown in Fig. 17 (c), only the first ply traverse device is shown in the figure. Thus, as shown in Fig. 17 (c), the plywood sheets A 5 and A 5 / are individually placed with the slight gaps away from the suction heads 43, 43 (only the plywood sheets A5 are shown). Thereafter, the motors 6 5, 6 5 / for the first and second plywood traverse devices are all pulsated. Although the movement of the lifter 5] and the related work of the first plywood traverse device will be described below with reference to FIGS. 18(a) to 18(d), the second plywood traverse device simultaneously produces the same operation. . The motor 6 5 drives the belt 6 1 to move the support block 53 fixed to the lift rod 5 1 to the right as indicated by the arrow in Fig. 18 (a) until the support block 53 is detected by the sensor 67 So far, the lifting rods 5 1 on which the plywood sheets A 4 and A 5 are placed are located directly above the plywood pallets 103, as shown in Fig. 18 (a). Then, the cylinders 1 2 3 are motivated to raise the upright rods 1 2 1 until they are all inserted through the holes 1 0 3 b formed in the plywood sheets 2, so that the composite ply sheets A4, A5 are rods 1 2 1 Push up to leave the stick 5 1, as shown in the picture! 8 (b). The belt 61 is driven by the motor 65 to move back to the support block 53 until it is detected by the sensor 68 as shown in Fig. 18 (c). Thereafter, the cylinders 2 3 are operated to retract the rods 1 2 1 such that the plywood sheets A 4 , A 5 are placed on the pallet 103 and the rods 51 are lowered by the motor to their original positions. Here, the block 5 1 a is detected by the sensor 57, as shown in Fig. 18 (d). As shown in Fig. 19 (a), the plywood 25- 1276523 (22) sheets A 4, A 4 / or A 5 , A 5 / which are placed on the pallet 103 are all adjacent thereto. The ends are set to be arranged one after another in relation to each other. The shipping plate 103 is sized and arranged such that it is placed in the plywood sheets A 4, A 5, A 4 , A 5 on the pallet 1 0 3 via the operations of the first and second ply traverse devices described above. The end of the plate A4 / of the heating plate 1 4 3, 1 5 5 adjacent to the hot press is spaced apart from the adjacent end face 1 〇 3 c of the pallet 1 〇 3 by a distance of about 0.02 mm. , as shown in the left side of Figure 19 (a). The servo motor 1 33 is motivated to move the chain conveyor 29 to the sixth end face of the plywood in the sixth layer of the initial base material 1 placed on the chain conveyor 1 29] (Fig. 1) Align the position of the adjacent end face 1 5 5 a of the upper heating plate 5 5 as shown in the right side of Figure 19 ( a ). Thereafter, the motor I 15 is actuated to move the belt 111 and the plywood pallet 103 until the end face 103c that reaches the pallet 103 is substantially aligned with the third end face 1e of the plywood in the third layer of the initial base material 1. The position is as shown in Figure 19 (b). The position of the belt 1 1 1 and thus the pallet 1 〇3 should be stopped by the control unit C. The control unit C reacts with the signal from the rotary encoder 1丨6 to control the motor 1] 5 operation 'code benefit 1 1 6 The current position of the pallet _3 associated with the predetermined reference position of the device is determined via the angle of rotation of the counting motor 1 15 . Then 'the solenoid valve 177 connected to the cylinder 169 via the fluid orifice 169 is turned on' and the servo motor 161 is actuated to lower the upper heating plate 155 until the heating plate 155 The lower surface arrives at a position spaced apart from the reference position of the aforementioned base material i by a distance corresponding to the thickness of the plywood sheet, that is, the lower surface of the upper heating plate 155 is brought into contact with the base material! ‘26 - 1276523 (23) The position of the fifth side lj of the plywood in the fifth layer is shown in Figure 2 (a). The upper heating plate]5 5 should stop at the position determined by the control unit c 'Control unit C reaction from the rotary encoder】 65 signal control servo motor 161 operation, encoder 165 via the counting motor 1 6 1 The angle of rotation determines the current position of the upper heating plate I 5 5 relative to the aforementioned predetermined reference position of the base material 1. After the motor 161 is stopped, the solenoid valve 7;! is closed. Then, the hydraulic cylinders 145, 145 are both priming to raise the lower heating plate 1 4 3 . When the lower heating plate 144 is moved upward, the carrier sheets a 4, A 5 , A 4 / , A 5 / the pallet 1 〇 3 thereon are separated from the belt 1 ι; and the heating plate 14 3 — Move up further until the plywood is squeezed as shown in Figure 2 (b). The plywood sheets a 4, A 4 /, A 5 and A 5 - are all pressed against the heating plate in the same position as shown in Fig. 19 ( a )! Between 5 5 and 1 4 3, and also the right end of the coated plywood sheets A4 / , A5 / adjacent to the initial base material 1 are set in the fourth and fifth layers of the initial basic material The fourth and fifth end faces lg and li of the individual plywood sheets are in facing relationship, as shown in Fig. 20 (c). Further, during the pressing, the entire surface area of the coated ply sheets A 4, A 4 is subjected to the pressure ' from the lower heating plate 1 4 3 and the same integral surface area is supported or carried by the upper heating plate 15 5 . This hot press is completed at a pressure of about 1 MPa and lasts for about three minutes. It must be noted that during this hot pressing, the auxiliary heating plates]45, 151, 173, 177 do not help the hot pressing of the plywood sheets. During this hot press, the control unit generates a command signal at a suitable time to initiate a series of work steps which will be performed during the three minutes of the aforementioned hot press for preparing the next set of ply pieces. . That is, • 27-1276523 (24) for the 'second transport lepton 73 and the first transport roller 29 are both driven to rotate, and the cylinder 8 5 / is operated such that the extension stop plate 8 3 < , as shown in Figure 2 ι ( a ). Simultaneously, the suction head 6 is operated to take out and feed the plywood sheet A6 - through the glue applicator 7, 2 3 as shown in Figure 2 1 (b). When the guide plate Α 涂覆 is detected by the sensor 75, the second transporter 7 3 is stopped and the first centering plate 7 7 , 7 9 (only one plate 7 9 is displayed) Both are operated to straighten and center the coated plywood sheet A 6 / as shown in Figure 2 1 (c). After the centering is completed, the second transport lepton 7 3 is rotated again to move the coated plywood sheet A 6 / . When the splicing plate A 6 / is reached before the leading end is detected by the sensor 8 丨 / detected position, the sufficiently long torrent leading end contacts the stop plate 8 3 after being detected by the sensor s 1 / After a predetermined length of time, the second transport roller 7 3 is stopped, as shown in Fig. 21 (d). After the cylinder 85 / is actuated, the stop plate 83 / is retracted as shown in Fig. 22 ( a ), and the servo motor 93 / is operated to raise the second suction head 87 / by holding by suction As shown in Figures 22(a) and 22(b), the plywood sheet A6 is then applied via the suction head 8 7 / up until it reaches a predetermined position above the plywood transport path. The servo motor 9 3 / is operated by the control unit C in response to the signal from the rotary encoder 95 / 5, and the encoder 95 / can be operated in the same manner as the encoder 165 for the motor 161. Then, the cylinder 85 is urged to extend the stopper plate 83 as shown in Fig. 2 2 (a). Simultaneously, when the second transport roller 73 is rotated again, and the suction head 6 can be operated to take out the plywood A6 and allow it to pass through the glue applicators 17, 23 as shown in Figures 22(a) and 22(c). ). When the coated plywood sheet A6 reaches the position where the leading end is detected by the sensor 75, the transporting roller 73 is stopped by -28- 1276523 (25) and the coated plywood sheet A 6 is centered by the centering plate 7 7 , 7 9 centering, as shown in Figure 2 2 (d). Thereafter, the conveying roller 7 3 is rotated again and the plywood sheet A6 is applied forward and backward. When the coated plywood sheet A 6 is moved to a position where the leading end is detected by the sensor 81, the leading end contacts the stopper plate 83 for a predetermined length of time before passing through a length of the plywood sheet A6, and is transported. The rollers 7 3 are all stopped, as shown in Fig. 23 (a), and the cylinders 85 are urged to move the stopper plates 83 to their retracted positions ' as shown in Fig. 23 (b). Similar to the operation illustrated with reference to Figures 2 2 (a) and 2 2 (b), the servo motor 93 is operated to raise the suction head 8 7 to a predetermined position above the plywood transport path, as shown in Figure 2 3 (b) With 2 3 ( c ). When the plywood sheets A6/A6 are thus placed at predetermined positions as shown in Fig. 23(b), the control unit C generates a command signal to ignite the motor (not shown) to be approximately 1 800. ° Rotating the pivots 9 2, 9 2 > for the oscillating motor support block 9 1 , 9 1 / and thus the suction heads 8 7 , 8 7 / , thus, as shown in Fig. 23 (d), the plywood A 6, A 6 / is disposed in such a manner that the coated surface thereof is installed in the square of the base material 1. As shown in Fig. 24 (a), the first transport roller 29 rotated in the direction of the arrow and the stopper plate 47 / 'the suction head 6 extended via the operating cylinder 49/ are operated to take out and feed the plywood The sheet A 3 / over-applicator 1 7 , 2 3 , as shown in Figure 24 (b) 'and moved forward until the coated sheet A3 / front-end sensor 3 is detected, as shown Figure 24 (c). In the position of Fig. 24(c), the coated plywood sheet A3 is centered by the centering plates 3 3, 35, and the transporting sliver 2 9 is rotated again and the plywood sheet A 3 / is moved forward until it The contact -29-1272623 (26) stopper plate 47 is the same as the above-described manner, for example, with reference to the plywood sheet A5/. The motor 5 5 / is operated to raise the lift bar 5 丨 / until its block 丨 ^ is detected by the sensor 58 / / so that the coated plywood sheet A3 / is held above the plywood transport path As shown in Figure 2 5 (a). The cylinders 49 / and 49 are then operated, as shown in Figure 25 (b), the stop plate 47 is retracted and the stop plate 47 is extended. By the first transport roller 29 being rotated, the suction head 6 is operated to take out and feed the plywood sheet A 3 through the applicator 1 7 , 2 3 as shown in Fig. 25 (b) 'and the plywood sheet A3 is Before moving until its leading end is detected by the sensor 31, as shown in Fig. 24(d), the coated plywood A3 is centered by the centering plates 3 3, 35. The transport rollers 29 are each rotated again to move the coated plywood sheet A3 forward. When the leading end of the plywood A3 arrives at the position detected by the sensor 37, the conveying roller 29 is stopped after a predetermined length of time is detected, so that the leading end of the plywood A3 contacts the stopper plate 47. , as shown in Figure 26 (a). The motor 55 is operated to raise the lift rod 5 1 until the block 5 1 a is detected by the sensor 58, as shown in Fig. 26(b). The cylinder 49 is actuated to move the stop plate 47 to its retracted position, as shown in Figure 26 (c). Then, the motors 5 5, 5 5 / are all operated simultaneously to lower the lift rods 5 1 , 5 ] until the sensors 5 8 , 5 8 / no longer detect the blocks 5 1 a, ' 5 1 a Up to now, as shown in Fig. 26 (d), only the first plywood traverse device is shown in the figure. Thus, as shown in Fig. 26(d), the plywood sheets A3, A3/ are individually placed with the micro-gap away from the attraction heads 43, 43 / . The foregoing operational steps with reference to Figures 21 to 26 are performed during the three minute hot extrusion operation of Figure 20(c). During this hot pressing, the adhesive feet -30-1276523 (27) are sufficiently cured to bond the two composite sheets A4, A4 - and A5, A5 - and the initial base material 1 to each other. Thereby, a new basic material including the added ply sheets A4, A4^, A5, A5/ is formed. For the sake of explanation, the basic material will be represented by reference numeral 1-1. After three minutes, control unit C generates a signal that first causes solenoid valve 1 7 1 (Fig. 8) to open and then causes servo motor to operate, causing the upper heating plate to move up to its original preparation. Position and actuate the hydraulic cylinder 1 4 5 to move the lower heating plate 4 3 to its original preparatory position, as shown in Figure 27. The shipping plate 103 is lowered with the lower heating plate 1 4 3 until it is engaged with the belt U 1 , and the projection 103 a of the shipping plate 103 is received in the hole 1 1 1 a of the belt 1 1 1 . Then, the motor 1 15 is pulsed to drive the belt 1 1 1 so that the pallet 103 joining the belt 11 1 is moved in the direction of the arrow as shown in Fig. 28 until the left end of the pallet 103 (shown in Fig. 28) is The sensor 1 1 7 is detected. Simultaneously, the motor 13 3 is also motivated to drive the chain carrier 2, 9 to move the sixth end face 1 k of the plywood in the sixth layer of the base material 1 - 1 to the base material 1 〇 1 in the direction of the arrow. The position of the adjacent end face of the coated plywood sheet A 6 / is aligned, as shown in the enlarged view of Fig. 28. Thereafter, the motors 6 5, 6 5 for the first and second plywood traverse devices are all pulsated. Although the movement of the lifter 51 and the associated operation of the first ply traverse device will be described with reference to Figs. 29(a) to 2 9(d), the second plywood traverse device simultaneously produces the same operation. The motor 6 5 drives the belt 6 1 to move the support block 53 fixed by the lift rod 5 1 to the right as indicated by the arrow in Fig. 29. (a) until the support block 53 is touched by the sensors -31 ~ 1276523 ( 28) 6 7 is detected, wherein the lifting bar 5 1 on which the plywood sheet 3 is placed is located directly above the plywood carrier plate 103, as shown in Fig. 29(a). Then, the cylinders 1 2 3 are motivated to raise the upright rods 1 2 until they are all inserted through the holes 1 〇 3 b formed in the plywood pallets 103, so that the plywood sheets A 3 are lifted by the rods 1 2 1 Push to leave the lift 5, as shown in Figure 2 9 (b). Belt 6 1 is driven by motor 6 5 to move back to support block 53 until it is detected by sensor 68, as shown in Figure 29(c). Thereafter, the cylinder 1 2 3 is operated to retract its rod].2 1 ' so that the plywood piece a 3 is placed on the pallet 1 〇 3, and the lift bar 5 5 is lowered by the motor 5 5 to its original Position, here, the block 5] 3 is detected by the sensor 57, as shown in Figure 29 (d). As previously mentioned, the second ply traverse device also performs a series of identical work steps such that the plywood sheet A3 / is placed on the pallet. As shown in Fig. 3, the plywood sheets A3, A3/ placed on the pallet 103 are each mounted one by one in such a manner that their adjacent ends are set to face each other. Then, the servo motors 93, 93 > are actuated to lower the suction heads 8 7 , 8 7 / as indicated by the arrows in Fig. 30 until the coated plies A 6 , A 6 / are placed so as to be in contact with the previous lamination The surface of the plywood sheets A5, A5/ and the fifth side lj of the plywood sheets in the fifth layer of the basic material 1 to 1, as shown in an enlarged view of FIG. After the motors 93, 93 / stop, the suction heads 8 7 , 8 7 / are no longer active via the closing of the combined switch (not shown), so the coated plywood sheets A6, A6# are placed in the base material. 1 on. As shown in Fig. 31 (a), the pivots 9, 2, 9 2 / are both rotated to oscillate the motor support blocks 9 1 , 9 ] with approximately 18, and thus the suction heads 8 7 , 8 7 / , then The servo motors 9 3, 9 3 / are all rotated to move the suction heads 8 7 , -32 - 1276523 (29) 87 / back to their original preparatory positions. The servo motor 133 is steered to move the chain conveyor 1 29 to the seventh end face 1 η of the plywood in the seventh layer of the base material 1-1 placed on the chain conveyor 1 29 substantially aligned 1 The position of the adjacent end face 1 5 5 a of the upper heating plate 1 5 5 is as shown in an enlarged view of Fig. 3 (b). Thereafter, the ipJ service motor for driving the belt 1 1 1 is operated to move the pallet 1 〇 3 in the direction of the arrow shown in Fig. 31 (b) until reaching the coated plate on the pallet 103 The leading end face of the sheet A 3 / (or the right-hand end shown in the drawing) is substantially aligned with the position of the third end face of the plywood in the third layer of the base material 1 - 1, as shown in 3 ] ( b ) Magnified view. Then, the cylinders 175 are all pulsed to lower the first auxiliary upper heating plate 1 7 3 by about 4 m, as shown in Fig. 31 (b). The solenoid valve 177 is opened, and the servo motor 161 is slid to lower the upper heating plate 155 until the lower surface of the upper heating plate 155 reaches the distance from the base material relative to the thickness of the double plunging plate The position of the reference position of one is spaced apart, that is, the position at which the lower surface of the upper heating plate 155 contacts the sixth surface 1 m of the plywood in the sixth layer of the basic material 1 a. An enlarged view on the right side of Figure 3 1 (c). After the upper heating plate 5 5 is positioned and the servo motor 116 is stopped, the solenoid valve 17 1 is closed. In the position of the aforementioned upper heating plate 155, a part of the upper surface of the slab A 5 as shown in the right side of Fig. 31 (c) contacts the first auxiliary upper heating plate 173. Then, the cylinder 149 is motivated to raise the first auxiliary heating plate 4 4 by about 4 mm, as shown in Fig. 3 1 (c), and the hydraulic cylinders 1 4 5, 4 5 are all ignited to -33- 1276523 (30) The lower heating plate 143 and the auxiliary lower heating plate 147 are raised. Thus, the carrier sheets A 3, A 3 / the pallet 1 〇 3 thereon are detached from the belt 1 1 1 and moved upward together with the heating plate 143 until the panel sheets A3, A3 <, A6, A 6 / are all pressed to the base material 1 - 1, as shown in Figures 3 2 (a) and 32 (b). As shown in Fig. 3 2 (b), the coated plywood sheet A 3 / is arranged to be in a facing relationship with the third end face 1 e of the plywood in the second layer of the base material. And extending through the second side of the plywood sheet in the fourth layer] and the previously laminated plywood sheet A4 / of the base material 1-1 of the portion. Similarly, the plywood sheet A 6 / is arranged such that its right end is in facing relationship with the sixth end face 1 k of the plywood sheet in the sixth layer of the base material 1 and extends through the plywood sheet in the fifth layer The fifth side lj and a part of the basic material 1 - 1 are first laminated to the laminated sheet A5 / . Further, during this hot pressing, the entire surface area of the coated ply sheets A3, A3 > is pressed by the lower heating plate 丨 4 3 and the same integral surface area is supported by the upper heating plate I 5 5 . In addition, the overall surface area of the coated ply sheets A6, A6 is subjected to pressure from the upper heating plate 155, and the main part of the same overall surface area is supported by the lower heating plate 143, and the extension thereof The remaining portion of the left end surface of the lower heating plate 143 is supported by the first auxiliary upper heating plate 147. The hot press shown in Figure 3 2 (b) is about the same pressure of about 1 MPa for about one minute. During this minute hot pressing, the two coated ply sheets 7 and 7 are all prepared in the same manner as the ply sheets A 6 and A 6 /, and placed in the basic as shown in Fig. 3 2 (c). Above the material I, and the two coated plies A 2 -34 - 1276523 (31) and A 2 / are all shown in Fig. 26 (c) in the same manner as the ply sheets a 3 and A 3 /. After one minute of hot pressing, control unit C produces a retracted position in which the lower and upper heating plates 1 4 3, 15 5 are moved back to Fig. 3 2 (c). The pallet 1 〇 3 is combined with the lower heating plate i 4 3 to engage the belt Π 1 . After this hot pressing, although not fully cured, the base material 1 - 1 and the plywood sheets A 3 , A 3 / , A6 are glued into one. Thus, a new basic material comprising additions of A 3 , A 3 / , Α ό, Α ό / is formed, which is represented by reference. Then, the motor 11 5 is pulsed to drive the belt ln to move the pallet 1 0 3 in the direction of the arrow until the left end 1 1 7 of the pallet 1 〇 3 is detected. Simultaneously, the motor i 3 3 is motivated to drive the machine to move the base material 1-2 to the base material. 〇 2 The seventh end face 1 η of the seventh plate is substantially aligned with the coated ply plate a 7 / The position is as shown in the enlarged view of Fig. 3 3. With the base material thus positioned]-2, the motors 9 3, 9 3 descend the suction heads 8 7 , 8 7 / in the direction of the arrow until the coated plies A 7 are positioned so as to be in contact with the surface of the previous laminated ply a 6 And the sixth surface of the plywood surface in the sixth layer of the basic material 1 - 2 is shown in an enlarged view of FIG. After the motor 9 3, 9 3 ' is stopped, the combined switch (not shown) causes the suction heads 87, 87 - not to be 'coated' the suction heads A7, A7 / are all placed in the basic material as shown in Figure 3. 4. Ready, for example, the signal is guided, as shown, until the adhesive is still 尙A 6, the number of the plate is added] 2 2 Figure 3 3 is the right end of the sensor chain transport layer / is operated now A7 ' "A6〆', as if by reclosing, I - 2, -35 - 1276523 (32) Then 'moving the chain conveyor 1 2 via the servo motor 1 3 3, the basic material 1 - 2 is moved in the direction of the arrow The eighth end face of the eighth laminate sheet is substantially aligned with the position of the adjacent end face 1 5 5 a of the upper heating plate 155 as shown in Fig. 35 (a). Then, the motor]]5 is driven to move the carrier plate 103 to the leading end (or the right-hand end of the drawing) of the coated plate A2 on the pallet 103 in the direction of the arrow of FIG. 3 5 ( a ) to substantially align the basic material. The position of the second end face 1 c of Fig. 2 is shown in Fig. 35 (a). Then, the cylinders 179 are all operated to lower the distance of the second auxiliary upper heating plate 1 7 7 by about 8 mm as shown in Fig. 35 (a). Thereafter, the solenoid valve 171 is opened, and then the servo motor 161 is actuated 'to lower the upper heating plate 155 until the lower surface of the upper heating plate 155 reaches the distance corresponding to the thickness of the triple-ply plate from the basic The position of the reference position of the material 1 - 2 is such that the lower surface of the upper heating plate 155 is in contact with the seventh surface Is of the base material 1 - 2 of the seventh laminate sheet, as shown in Fig. 35 (b) ). After the upper heating plate 155 is positioned and the servo motor 116 is stopped, the solenoid valve 17 is closed. To thereby position the upper heating plate 155, as shown in the enlarged view of Fig. 35(b), the first and first upper auxiliary heating plates 173, 177 are placed with the individual coated ply plates A6 and A5. Upper surface contact bonding ° Cylinder 1 5 3 is also operated to raise the distance of the second lower auxiliary heating plate 1 5 1 by approximately 8 mm as shown in Figure 35 (b). Next, through the operation of the cylinder 14 5, the lower heating plate 1 4 3 and the shipping plate 1 〇 3 are raised for hot pressing of the plates A2, A2 / , A7, A7 / to the basic material 1-2, as shown At -36- l276523 (33) Figure 35 (c). As shown in Fig. 36 (a), the coated plywood sheet A2 is faced at its right end (viewed by the drawing) and the second end face 1c of the plywood in the second layer of the base material 1-2. The relationship is extended by the second face of the ply sheet in the third layer of the base material 1 - 2 and a portion of the previous laminated ply a 3 -. Similarly, the coated plywood sheet A7 is faced with a right end end thereof in a facing relationship with the seventh end face 1 n of the plywood sheet in the seventh layer of the base material 1-2, and extends through the sixth layer of the basic material 1 to 2 The sixth side of the plywood piece is 1 m and a part of the previous laminated ply piece a 6 / is pressed. In addition, during the hot pressing, the entire surface area of the coated ply sheets A 2, A 2 / is pressed by the lower heating plate 1 4 3 , and the same integral surface area is supported by the upper heating plate 15 5 . On the other hand, the entire surface area of the coated ply sheets a 7 , A 7 / is pressed by the upper heating plate 15 5 , and the main part of the same overall surface area is supported by the lower heating plate 1 4 3 , and The extension of the left end surface of the lower heating plate 143 is supported by the first auxiliary lower heating plate 147. In addition, the contact area between the plywood sheets a 3, A 4 which is not covered by the lower heating plate 134 and which is only hot pressed for a minute in the previous hot pressing operation is subjected to the lower portion from the first auxiliary The heating plate] 4 7 heat and pressure, and the same area is from the upper heating plate! 5 5 and the first auxiliary upper heating plate 173 are supported. Also for the partial contact area between the plywood sheets A7, A6 and not covered by the upper heating plate 155. The portion of the contact area is subjected to heat and pressure from the first auxiliary upper heating plate 173 and is supported by the first and second auxiliary lower heating plates 147, 157. Therefore, the hardening of the adhesive in these areas is promoted toward complete hardening. -37- 1276523 (34) The hot press in Figure 3 5 (a) lasts approximately one minute at the same pressure of approximately 1 MPa. The adhesive applied to the ply sheets A 2, A 2 / begins to harden by the heat transferred from the lower heating plate 143 through the pallet 103. In addition, the heat from the lower heating plate 143 is also transferred to the plywood sheets A3, A3 / via the plywood sheets A2, A2 / or directly by the first lower auxiliary heating plate 1 47, and thus, in this hot pressing operation, The adhesive on the plywood sheets A3, A3 is further continuously hardened. Similarly, the adhesive applied to the plywood sheets A7, A7 / is hardened by the heat transferred from the upper heating plate 5 5 , and from the same heating plate 5 5 via the plywood sheets a 7 , A 7 / or directly It is transferred to the heat of the plywood sheets A6, A6 / by the first upper auxiliary heating plate 173 to assist in enhancing the hardening of the adhesive on the plywood sheets A6, A 6 /. After the extrusion, although the adhesive is still not fully cured, the base material 1-2 and the plywood sheets A2, A2, A7, and A7 are glued together. Therefore, the formed laminate sheets A2 and A2 are formed. <, A7, A7, new basic materials, which will be represented by reference numbers 1 - 3. Although the detailed description is omitted, two pairs of coated ply sheets A are separately prepared in the same manner as the plywood sheets A 6 , A 6 / and the plywood sheets A 3 , A 3 / during one minute of the above-described hot pressing operation. 8, A 8 / and A 1, A 1 /. After the one-minute hot press is completed, a series of work steps are performed for placing and hot pressing the two composite sheets A 1 , A 1 / , A 8 , A 8 . Since the manner in which such an operation is performed is substantially the same as in the case of the plywood sheets A 2, A 2 / and A 7 , A 7 /, the detailed description thereof will be omitted. It must be noted, however, that this hot press is approximately -38 to 1276523 (35) for two minutes at the same pressure of approximately 1 MP a. During the two hot extrusions shown in Fig. 36 (b), the coated plywood sheet A 1 / is laminated at its right end (viewed by the drawing) and the first layer of the base material 1 - 3 The first end face 1c is in a facing relationship and is extruded through the first face 1b of the plywood in the second layer of the base material 1-3 and a portion of the previous laminated plywood A2/. Similarly, the coated plywood sheet A8 is oriented in a facing relationship with the eighth end face 11 of the plywood in the eighth layer of the base material 1 - 3 and extends through the base material - 3 t-th layer The seventh side of the plywood sheet is pressed for the seventh side 1 s and part of the previous laminated plywood sheet A 7 /. Further, during this hot pressing, the entire surface area of the plywood sheets A1, A丨/ is pressed by the lower heating plate 143, and the same integral surface area is supported by the upper heating plate 155. On the other hand, the entire surface area of the coated ply sheets A 8 and A 8 / is pressed by the upper heating plate 15 5 , and the main part of the same overall surface is supported by the lower heating plate 43 . The remaining portion extending beyond the left end surface of the lower heating plate 143 is supported by the first auxiliary lower heating plate 147. It can be easily understood from the comparison of Figure 3 6 (a) by providing heat and pressure to those between the plywood sheets A2, A3 and A6, A7 and not individually covered by the lower and upper heating plates 143, 155 and previously hot pressed The portions of the contact areas that are only heated for one minute during the squeezing operation, in this case, the auxiliary heating plates can also be efficiently processed. Further, in the portion of the contact region between the plywood sheets A 3, A 4 and A 6 , A 7 , heat is directly received from the second auxiliary heating plates 1 5 1 and 17 7 . Fig. 3 6 (b) The hot pressing system lasts for about three minutes at the same pressure of about 1 MPa -39· 1276523 (36) After the above-mentioned three-minute hot pressing operation, although the adhesive is still not completely The ground material 'base material 1 - 3 and the plywood sheets a 1 , A 1 /, A 8 , and Α·8 are coated and bonded together. Thus, as shown in Fig. 37 (a), a new base material 1 / is formed, and the end portion thereof is formed into a ladder plate substantially identical to the initial base material shown in Fig. 11. . Then, the control unit C generates a signal to cause the individual upper and lower heating plates 1 5 5, 1 4 3, the first and second upper auxiliary heating plates 7 7 , 丨 7 7 , and the first and second lower auxiliary heating The plate 1 4 7 , 1 5 ] is retracted to its original preparatory position as shown in Figure 37 (a). Then, the motor 155 is operated to drive the belt 1 1 1 to move the pallet 1 〇 3 back to its original preparatory position in the direction of the arrow of Fig. 37 (b). Simultaneously, the motor 13 3 is operated to move the chain conveyor 1 2 9 in the direction of the arrow until the base material 1 carried by the chain conveyor] 2 9 reaches the plywood A6 in the sixth layer of the base material 1 / The end face 1 k / substantially aligned with the upper heating plate} 5 5 end face 丨 5 5 a, as shown in Figure 3 7 (b). Then, a series of work steps as described in Figs. 12 through 37 are repeated as many times as needed to produce the desired eight-layer LVL board. In the foregoing description of the preferred embodiment, a laminated ply assembly having a plywood having a thickness of about 4 mm for each of the eight layers as shown in Fig. 11 is used as the initial basic material, from which One end is made into a continuous length LVL plate. If the thickness of the plywood or the number of layers is changed, the aforementioned reference position associated with the attraction of the attraction heads 8 7 , 8 7 / and the upper heating plate 15 5 is also changed. In this case, the reference position can be established in the same manner as the preferred embodiment described above. That is, the reference position can be set at an intermediate position when the thickness of the new initial base material carried on the chain -40-(37) (37) 1276523 conveyor 1 2 9 is measured from the thickness of the traverse base material. When the number of layers changes, it is also necessary to set a new reference position. In this case, in each of the complete operating cycles covering the steps illustrated in the preferred embodiments of Figures 2 through 37, the first and last hot press steps (or Figure 20 in the preferred embodiment) (c) The length of time during the hot extrusion in Figure 3 6 (b)) can be set longer than other similar steps. While the invention has been described and described with reference to the specific embodiments of the invention, the invention may be In the comparative embodiment, as shown in Fig. 2, the plywood sheets are prepared as a 'group' for the cum layer and are disposed one after another with their adjacent ends set to be mutually reciprocal. However, the number of sheets of one of the composite sheets prepared may be more than two. Alternatively, a single plywood sheet can be provided as a composite sheet. The modified embodiment shown in Fig. 3 8 (a) and 3 8 (b) is different from the preferred embodiment in that the upper heating plate is fixed, and the chain conveyor 1 29 is as shown in Fig. 38. The double-headed arrow in (a) moves vertically as shown by the direction of the arrow, so that the basic material carried thereon can be vertically and horizontally moved to achieve this goal, providing a servo motor 2 9 / and a threaded shaft, One of the threaded shafts is connected to and rotated by the motor 2/9 for controllably moving the chain conveyor vertically. The chain conveyor 1 29 is generally in its lowered position as shown in Figure 38 (a) and can be controllably moved in the horizontal direction in the same manner as in the preferred embodiment for relative to, for example, For upper heating -41 - 1276523 (38) Plate 1 5 5 / Right end face 1 5 5 a / Positioning basic material. In the hot pressing operation, the chain conveyor 1 29 having the basic material thereon is moved upward by the motor 1 29 - corresponding to the distance at which the upper heating plate 155 is lowered in the comparative embodiment. Thus, the laminated panel assembly is positioned as shown in Figure 38 (b). Then, the lower heating plate 143 is raised to apply a pressure of about i MPa$. Figure 3 9 (a) shows an alternative form of the initial laminate panel assembly 1 in which one end of the first to fifth laminate sheets is cut or cut at a predetermined angle and angled. The surface is facing downward, and at one end of the sixth to eighth ply sheets, the oblique angle is cut at the same angle of the opposite direction so that the beveled surface faces upward. As shown in Fig. 39 (b), the opposite ends of the ply sheets laminated to the base material are cut at an oblique angle at the same angle in the same direction, so that the relative beveled surfaces of each plywood are mutually Parallel to extend. As shown in Fig. 39 (b), the plywood sheets are laminated in such a manner as to form a lap joint between any two adjacent plywood sheets in the same layer. Although the end portion of the ply sheet indicated by Q is only subjected to the reduced pressure during hot pressing, since the portion is small, the normal strength of the produced LVL plate is not affected. In a preferred embodiment and the modified embodiment of Figure 39 (a), the first end of the eight-ply laminate is initially formed into a stepped two-ladder form, and the first step of the step formed by the fifth to eighth ply pieces The plate system faces upward, and one of the steps formed by the first to fifth ply sheets faces downward. The present invention is not limited to the initial base material in one form, but may provide an initial base material - 42 - 1276523 (39) via, for example, only the first to fifth layers of the base material of Figure 1]. Thus, the end of the resulting base material has the form of a single riser facing the step below. In the case of using such an initial base material, the laminate sheets A 4 , A 4 / , A 5 , A 5 - are all laminated in substantially the same manner as the steps of Figure 2 (c). In the step corresponding to Fig. 3 2 (b), only the plywood sheets A3, A3 / are laminated. In the steps corresponding to Figs. 36(a) and 36(b), only the plywood sheets A2, A2/ and A], Ai- are individually adhered to the base material. Although in the preferred embodiment, two auxiliary heating plates are provided adjacent one end of each of the upper and lower heating plates. The invention does not limit the number of auxiliary heating plates used, and may have only one auxiliary heating plate or alternatively more than two similar heating plates. In addition, the configuration of the upper and lower heating plates can be reversed. That is, a heating plate having a cylinder such as 169 and moved by a servo motor such as 161 and having a rotary encoder such as 165 can be used as the lower heating plate, and one is such as 1 4 The heating plate moved by the cylinder of 5 can be used as the upper heating plate.
