It is a controller.

本発明の実施例は、以上のように備えるもので、次に単板を厚さ方向に３枚重ねる場合の作用を説明する。
最初に初期状態として、縦矧装置３は搬送状態、ロール５及びロール９は走行させ、第１丸鋸７を図１の実線で示す位置で待機させ、また移動・反転装置１１は、図１、図２で示す待機位置で、エアシリンダ２１は待機位置で且つ図５で示すように回動バー３７は上昇位置で、更にはエアシリンダ３１は図３で示すピストンロッド３１ａが突出しきった限度位置で、エアシリンダ３９は待機位置で各々待機させておく。またプレッダ４３の塗布ロール４３ａ及びドクターロール４３ｂは、図６に示す通過位置に移動待機させておく。更には、バキューム装置（図示せず）から各吸着カップ７１に通じるに各開閉弁は閉状態としておく。また、コールドプレス７７は、離隔位置に上側プレス８５を待機させておく。 The embodiment of the present invention is provided as described above. Next, the operation when three single plates are stacked in the thickness direction will be described.
First, as an initial state, the downpipe device 3 is in the transport state, the rolls 5 and 9 are run, the first circular saw 7 is kept waiting at the position indicated by the solid line in FIG. 1, and the moving / reversing device 11 is 2, the air cylinder 21 is in the standby position, the rotation bar 37 is in the raised position as shown in FIG. 5, and the air cylinder 31 is the limit where the piston rod 31a shown in FIG. In the position, the air cylinders 39 are kept waiting at the standby positions. In addition, the application roll 43a and the doctor roll 43b of the pre-placer 43 are kept waiting for movement at the passing positions shown in FIG. Furthermore, each on-off valve is kept closed so as to communicate with each suction cup 71 from a vacuum device (not shown). Further, the cold press 77 causes the upper press 85 to stand by at a separation position.

該状態で図１に示すように、単板１を繊維方向に縦矧装置３に順次挿入し、板同士の繊維方向端部を接合部１aとして接合し、接合単板１ｂとする。
接合単板１ｂはロール５により搬送され、その搬送方向下手側（以下、先端側という）端縁が二点鎖線で示す位置に到達し第１検知器２aにより検知されると、該信号を受けた制御器９５から出される信号により、縦矧装置３での搬送、ロール５及びロール９の走行を停止させる。
次いで制御器９５から出される信号により、実線の位置で待機している第１丸鋸７を二点鎖線で示す位置まで移動させ、接合単板１ｂの先端を実線で示すように繊維方向に対し傾斜した方向に切断し、傾斜辺１ｃを形成する。尚、この切断で三角形の単板が切断分離されるが、これは手作業によりロール５上から排除する。
第１丸鋸７が二点鎖線で示す位置に到達するために十分な時間が経過したことを制御器で検出した後、制御器からの信号で、第１丸鋸７の移動を停止させると共に、ロール５及びロール９の走行を再開させる。
尚、第１丸鋸７は前記停止後、接合単板１ｂの移動に妨げとならないような位置まで下降した後、実線で示す原位置に移動復帰させておく。 In this state, as shown in FIG. 1, the veneer 1 is sequentially inserted in the downpipe device 3 in the fiber direction, and the end portions in the fiber direction of the plates are joined as a joint 1a to obtain a joined veneer 1b.
The bonded single plate 1b is transported by the roll 5, and when the lower edge in the transport direction (hereinafter referred to as the front end side) reaches the position indicated by the two-dot chain line and is detected by the first detector 2a, it receives the signal. In response to a signal output from the controller 95, the transport of the downspout apparatus 3 and the traveling of the roll 5 and the roll 9 are stopped.
Next, the first circular saw 7 waiting at the position of the solid line is moved to the position indicated by the two-dot chain line by the signal output from the controller 95, and the tip of the bonded single plate 1b is directed to the fiber direction as indicated by the solid line. Cut in an inclined direction to form an inclined side 1c. In addition, although the triangular single plate is cut and separated by this cutting, this is removed from the roll 5 by manual work.
After the controller detects that sufficient time has passed for the first circular saw 7 to reach the position indicated by the two-dot chain line, the movement of the first circular saw 7 is stopped by a signal from the controller. The traveling of the roll 5 and the roll 9 is resumed.
After the stop, the first circular saw 7 is lowered to a position that does not hinder the movement of the bonded single plate 1b, and then moved back to the original position indicated by the solid line.

接合単板１ｂはロール５により単板１の挿入方向に搬送され、やがて傾斜辺１ｃが第２検知器２ｂにより検知されると、該信号を受けた制御器９５は、同様に信号を出し、縦矧装置３での搬送及びロール５及びロール９の走行を停止させる。
次いで前記と同様に、制御器９５からの信号で、第１丸鋸７を移動させて切断し、図４の二点鎖線で示すように、傾斜辺１ｃの長さが短辺の長さ１ｅの長さの２倍となる平行四辺形で、角度αが６０度で、角度βが１２０度となる単位単板１ｄ−１を形成する。 The bonded single plate 1b is conveyed in the insertion direction of the single plate 1 by the roll 5, and when the inclined side 1c is eventually detected by the second detector 2b, the controller 95 receiving the signal similarly outputs a signal, The transportation in the downspout apparatus 3 and the traveling of the roll 5 and the roll 9 are stopped.
Next, in the same manner as described above, the first circular saw 7 is moved and cut by a signal from the controller 95, and as shown by the two-dot chain line in FIG. 4, the length of the inclined side 1c is the length 1e of the short side. A unit single plate 1d-1 having a parallelogram that is twice as long as the angle α, the angle α being 60 degrees, and the angle β being 120 degrees is formed.

次いで制御器９５は、移動・反転装置１１が待機位置にあるという条件で、ロール９を作動させて単位単板１ｄ−１を搬送し、その先端側傾斜辺１ｃが第３検知器４に検知されると、該信号を受けた制御器９５は信号を出し、縦矧装置３での搬送、及びロール５及び９の各走行を停止させる。
この時、単位単板１ｄ−１は、図１、図２、図４及び図５に示す位置にある。尚、図４では、便宜上、単位単板１ｄ−１を二点鎖線で示してある。
次いで制御器９５から出される信号により、各挟持保持体３３のエアシリンダ３９を作動させてピストンロッド３９ａを前進させることで、回動バー３７を図５の二点鎖線で示す位置に回転下降させ、単位単板１ｄ−１を第１基体３５との間で挟持する。
この場合、図４から明らかなように、単位単板１ｄ−１の、第１回転軸１３の軸中心線方向で一方側端部（図４で上方）付近の形状は鋭角となった先端部分であるため、対応する挟持保持体３３の、第１回転軸１３の半径方向での長さが短くて良い。 Next, the controller 95 operates the roll 9 to convey the unit single plate 1d-1 under the condition that the moving / reversing device 11 is in the standby position, and the tip side inclined side 1c is detected by the third detector 4. Then, the controller 95 that has received the signal outputs a signal, and stops the conveyance of the downside apparatus 3 and the traveling of the rolls 5 and 9.
At this time, the unit single plate 1d-1 is in the position shown in FIG. 1, FIG. 2, FIG. 4 and FIG. In FIG. 4, for convenience, the unit single plate 1d-1 is indicated by a two-dot chain line.
Next, in response to a signal output from the controller 95, the air cylinder 39 of each holding holder 33 is operated to advance the piston rod 39a, thereby rotating the rotating bar 37 to the position indicated by the two-dot chain line in FIG. The unit single plate 1 d-1 is sandwiched between the first base 35.
In this case, as is apparent from FIG. 4, the tip portion of the unit single plate 1d-1 near the one end (upward in FIG. 4) in the axial center line direction of the first rotation shaft 13 has an acute angle. Therefore, the length of the corresponding holding body 33 in the radial direction of the first rotating shaft 13 may be short.

前記挟持後、制御器９５から出される信号により、両第１保持体１５のエアシリンダ３１のピストンロッド３１ａを中間位置まで後退作動させる。
その結果、図１２及び図１３に示すように、取付部材２５、第１回転軸１３、モータ２３等が一体で上昇し、各挟持保持体３３も上昇するため、単位単板１ｄ−１は前記挟持された状態で、ロール９から離れる。
次いで制御器９５から出される信号により、各エアシリンダ２１を、図１４に示すように、ピストンロッド２１ａを突出しきった前進位置まで移動させる。
その結果、移動・反転装置１１の要部だけを示す平面説明図である図１５に示すように、ロール４１の上方に単位単板１ｄ−１が至る。 After the clamping, the piston rod 31a of the air cylinder 31 of both the first holding bodies 15 is moved back to the intermediate position by a signal output from the controller 95.
As a result, as shown in FIGS. 12 and 13, the mounting member 25, the first rotating shaft 13, the motor 23, and the like are raised together, and the holding members 33 are also raised. In a state of being pinched, the roll 9 is separated.
Next, each air cylinder 21 is moved by the signal output from the controller 95 to the forward position where the piston rod 21a is fully projected, as shown in FIG.
As a result, the unit single plate 1 d-1 reaches above the roll 41 as shown in FIG. 15 which is a plan explanatory view showing only the main part of the moving / reversing device 11.

次に制御器９５から出される信号により、エアシリンダ３１をピストンロッド３１ａが前進位置に至るまで作動させる。
その結果、第１保持体１５及びその周辺の部分側面説明図である図１６に示すように、第１基体３５の上面がロール４１で構成される搬送面により低い位置となり、単位単板１ｄ−１はロール４１に当たる。
次いで制御器９５から出される信号により、エアシリンダ３９を作動させ回動バー３７を図の実線で示す位置と同様の待機位置に移動させる。
その結果、単位単板１ｄ−１は第１基体３５及び回動バー３７による挟持が開放される。
次いで、各ロール４１を回転させると、単位単板１ｄ−１はグルースプレッダ４３に向かって搬送される。 Next, the air cylinder 31 is operated by the signal output from the controller 95 until the piston rod 31a reaches the forward movement position.
As a result, as shown in FIG. 16 which is a partial side view for explaining the first holding body 15 and its periphery, the upper surface of the first base 35 is positioned lower than the conveying surface constituted by the roll 41, and the unit single plate 1d- 1 hits the roll 41.
Next, the air cylinder 39 is actuated by a signal output from the controller 95 to move the rotation bar 37 to a standby position similar to the position indicated by the solid line in the figure.
As a result, the unit single plate 1d-1 is released from being held by the first base body 35 and the rotation bar 37.
Next, when each roll 41 is rotated, the unit single plate 1 d-1 is conveyed toward the glue spreader 43.

尚、搬送される単位単板１ｄ−１の搬送方向上手側（以下、終端側という）短辺１ｅが、グルースプレッダ４３側の支持バー１９の箇所を通過し終えるために十分な時間が経過すると、制御器９５から出される信号により各部材を作動させ、後続の単位単板１ｄ−２をロール４１上へ供給するための準備をさせる。即ち、エアシリンダ２１を前記とは逆に作動させて、移動・反転装置１１を、図２で示した待機位置まで移動させ待機させ且つエアシリンダ３１を作動させピストンロッド３１ａを前進位置まで突出させておくと共に、後述するように、縦矧装置３を作動させて単板１を順次接合する。   In addition, when sufficient time passes for the conveyance direction upper side (henceforth a termination | terminus side) short side 1e of the unit single board 1d-1 conveyed to pass through the location of the support bar 19 by the side of the glue spreader 43 side. Each member is actuated by a signal output from the controller 95 to prepare for supplying the subsequent unit single plate 1d-2 onto the roll 41. That is, the air cylinder 21 is operated in the opposite direction, the moving / reversing device 11 is moved to the standby position shown in FIG. 2 for standby, and the air cylinder 31 is operated to cause the piston rod 31a to protrude to the forward position. In addition, as described later, the downboard device 3 is operated to sequentially join the single plates 1.

前記ロール４１で搬送される単位単板１ｄ−１は、やがてグルースプレッダ４３の箇所を通過するが、前述の図６で示したように、塗布ロール４３ａ及びドクターロール４３ｂが通過位置にあるため、接着剤は塗布されない。
前記スプレッダ４３の箇所を通過した単位単板１ｄ−１は、ロール４５により更に搬送され続け、その搬送方向下手側短辺１ｅが第４検知器６により検知されると、該検知信号を受けた制御器９５から出される信号により、ロール４５、ロール４１を停止させる。
この段階で単位単板１ｄ−１は、搬送・反転装置４７の各吸着バー６５ａ，６５ｂ、６７ａ，６７ｂ、６９ａに対し、図１０の二点鎖線で示す位置にある。
次いで制御器９５から出される信号により、エアシリンダ６３を作動させ、中間停止位置までピストンロッド６３ａを上昇させる。
その結果、第２回転軸５１が上昇し、これに設けられている各吸着バーも上昇し、例えば吸着バー６９ａだけを示すが図１７に示すように単位単板１ｄ−１は、その下面を各吸着カップ７１により支持されて持ち上げられ、ロール４５から離れる。 The unit single plate 1d-1 conveyed by the roll 41 eventually passes through the location of the glue spreader 43, but as shown in FIG. 6 described above, the application roll 43a and the doctor roll 43b are in the passing position. Adhesive is not applied.
The unit single plate 1d-1 that has passed through the place of the spreader 43 continues to be further conveyed by the roll 45, and when the lower side 1e in the conveying direction is detected by the fourth detector 6, the detection signal is received. The roll 45 and the roll 41 are stopped by a signal output from the controller 95.
At this stage, the unit single plate 1d-1 is in a position indicated by a two-dot chain line in FIG. 10 with respect to the suction bars 65a, 65b, 67a, 67b, 69a of the transport / reversing device 47.
Next, the air cylinder 63 is operated by a signal output from the controller 95, and the piston rod 63a is raised to the intermediate stop position.
As a result, the second rotating shaft 51 is raised, and each suction bar provided on the second rotating shaft 51 is also raised. For example, only the suction bar 69a is shown, but as shown in FIG. It is supported and lifted by the suction cups 71 and leaves the roll 45.

次いで制御器９５から出される信号により、バキューム装置（図示せず）から単位単板１ｄ−１に対応する吸着バー６５ａ，６９ａ及び６７ｂの各吸着カップ７１に通じるに各開閉弁を開作動させて、単位単板１ｄ−１を吸着保持する。
次に制御器９５は作動信号を出しモータ５５を反時計回りに１８０度回転させ、図１８に示すように、各吸着カップ７１に吸着保持された状態の単位単板１ｄ−１を反転させてチェーンコンベア７５の上方に移動させる。
次いで制御器９５から出される信号により、エアシリンダ６３を作動させ、ピストンロッド６３ａを前記後退位置に移動させる。
そこで第２回転軸５１及び各吸着バーは下降し、図１９に示すように、前記吸着保持された単位単板１ｄ−１がチェーンコンベア７５に当たる。 Next, in accordance with a signal output from the controller 95, each on-off valve is opened to communicate from the vacuum device (not shown) to the suction cups 71 of the suction bars 65a, 69a and 67b corresponding to the unit single plate 1d-1. The unit single plate 1d-1 is adsorbed and held.
Next, the controller 95 issues an operation signal, rotates the motor 55 counterclockwise by 180 degrees, and inverts the unit single plate 1d-1 held by the suction cups 71 as shown in FIG. Move to above the chain conveyor 75.
Next, the air cylinder 63 is operated by a signal output from the controller 95, and the piston rod 63a is moved to the retracted position.
Then, the second rotating shaft 51 and each suction bar descend, and the unit single plate 1d-1 held by suction hits the chain conveyor 75 as shown in FIG.

次に制御器９５から出される信号により、開状態となっていた各開閉弁を閉作動させて吸着カップ７１による単位単板１ｄ−１の吸着を中止し、次いでエアシリンダ６３を作動させピストンロッド６３ａを中間位置へと作動させてから停止させ、第２回転軸５１を図１８に示した位置と同じ位置に上昇させる。
次いでモータ５５により第２回転軸５１を前記とは逆、即ち図１８で時計回りに１８０度回転させる。
その結果、部分平面図である図２０に示すように、単位単板１ｄ−１はチェーンコンベア７５上に残り、各吸着バー６５ａ，６５ｂ、６７ａ，６７ｂ、６９ａは、元の位置に戻る。
尚、後述するように各単位単板は３層となるように重ねるが、便宜上、各図面では、最下層の単位単板にαを、２層目の単位単板にβを、最上層の単位単板にγをつけて示す。また線が多数示されることによる分かりにくさを避けるため、チェーンコンベア７５上に載置した各単位単板の接合部１aの線は示さないことにする。
前記各吸着バー６５ａ，６５ｂ、６７ａ，６７ｂ、６９ａは、元の位置に戻ると、コンベア７５を単位単板１ｄ−１の搬送方向の長さだけ走行させた後、再び停止させ、図２１に示す位置に待機させておく。 Next, in response to a signal output from the controller 95, each open / close valve that has been opened is closed to stop the suction of the unit single plate 1d-1 by the suction cup 71, and then the air cylinder 63 is operated to move the piston rod. 63a is operated to an intermediate position and then stopped, and the second rotating shaft 51 is raised to the same position as that shown in FIG.
Next, the motor 55 rotates the second rotating shaft 51 by 180 degrees in the reverse direction, that is, clockwise in FIG.
As a result, as shown in FIG. 20 which is a partial plan view, the unit single plate 1d-1 remains on the chain conveyor 75, and the suction bars 65a, 65b, 67a, 67b, 69a return to their original positions.
As will be described later, each unit single plate is stacked in three layers. However, for convenience, in each drawing, α is the lowest unit single plate, β is the second unit single plate, The unit single plate is indicated with γ. In addition, in order to avoid difficulty in understanding due to the fact that a large number of lines are shown, the lines of the joint portions 1a of the unit single plates placed on the chain conveyor 75 are not shown.
When each of the suction bars 65a, 65b, 67a, 67b, 69a returns to the original position, the conveyor 75 is caused to travel for the length of the unit single plate 1d-1 in the transport direction, and then stopped again. Wait at the position shown.

一方、前記のように単位単板１ｄ−１をプレッダ４３に向けて搬送し、また移動・反転装置１１を、図２で示した待機位置で待機させた後、制御器９５から出される信号により、縦矧装置３による単板の接合を再開させる。
即ち、縦矧装置３に単板１を供給して接合し、また縦矧装置３の搬送・停止に同調させてロール５及びロール９を搬送・停止させて、順次接合単板１ｂを移動・反転装置１１に向けて搬送する。
接合単板１ｂの傾斜辺１ｃが第２検知器２ｂに検知されると、単位単板１ｄ−１の場合と同様に第１丸鋸７により切断され単位単板１ｄ−２となる。次いで単位単板１ｄ−２は更に搬送され、先端側切断部１ｃが第３検知器４に検知されると、図２に示す１ｄ−１と同様の位置で停止する。
以後、単位単板１ｄ−１の場合と同様の移動・反転装置１１の各部材の作動により、単位単板１ｄ−２を反転することなくロール４１上へと移動・載置させ、この状態で待機させておく。 On the other hand, after the unit single plate 1d-1 is conveyed toward the pre-der 43 as described above and the moving / reversing device 11 is put on standby at the standby position shown in FIG. Then, the joining of the single plate by the downspout device 3 is resumed.
That is, the single plate 1 is supplied to and joined to the downspout apparatus 3, and the roll 5 and the roll 9 are transported and stopped in synchronization with the transport / stop of the downspout apparatus 3, and the joined single plate 1 b is sequentially moved / stopped. It is conveyed toward the reversing device 11.
When the inclined side 1c of the bonded single plate 1b is detected by the second detector 2b, the unit single plate 1d-2 is cut by the first circular saw 7 as in the case of the unit single plate 1d-1. Next, the unit single plate 1d-2 is further transported, and when the distal end side cutting portion 1c is detected by the third detector 4, it stops at the same position as 1d-1 shown in FIG.
Thereafter, the unit single plate 1d-2 is moved and placed on the roll 41 without being reversed by the operation of each member of the moving / reversing device 11 similar to the case of the unit single plate 1d-1, and in this state Let's wait.

前記単位単板１ｄ−２をロール４１上で待機させた状態で、第２回転軸５１を図１８で時計回りに１８０度回転させた後、制御器９５からの信号により、ロール４１、ロール４５を走行させる。
そこで単位単板１ｄ−２はスプレッダ４３を通りロール４５で搬送され、第４検知器６によりその先端側短辺１ｅが検出されるとロール４５が停止し、図１２に示す状態に、単位単板１ｄ−２が位置する。尚、単位単板１ｄ−２がスプレッダ４３を通る祭、スプレッダ４３は依然として図６に示すように設定されているので、同様に接着剤は塗布されない。 In a state where the unit single plate 1d-2 is kept on the roll 41, the second rotating shaft 51 is rotated 180 degrees clockwise in FIG. To run.
Therefore, the unit single plate 1d-2 passes through the spreader 43 and is conveyed by the roll 45. When the front end side short side 1e is detected by the fourth detector 6, the roll 45 is stopped, and the unit single plate 1d is in the state shown in FIG. Plate 1d-2 is located. Note that when the unit single plate 1d-2 passes through the spreader 43, the spreader 43 is still set as shown in FIG. 6, so that no adhesive is applied.

次いで、制御器９５からの信号により、単位単板１ｄ−２を、単位単板１ｄ−１の場合と同様の動作により搬送・反転装置４７を作動させて反転させ、チェーンコンベア７５上に載置し、各吸着バーでの吸着を中止する。その結果、図２２に示すように、単位単板１ｄ−１及び１ｄ−２が短辺１ｅ同士を密接させた状態で並べられる。
尚、単位単板１ｄ−２の先端側短辺１ｅが第４検知器６により検出されると、該信号を受けた制御器９５からの信号により、スプレッダ４３の塗布ロール４３ａ及びドクターロール４３ｂを図７で示す塗付位置に下降停止させておく。 Next, the unit single plate 1d-2 is reversed by operating the conveying / reversing device 47 by the same operation as that of the unit single plate 1d-1 in accordance with a signal from the controller 95, and placed on the chain conveyor 75. Then, the adsorption at each adsorption bar is stopped. As a result, as shown in FIG. 22, the unit single plates 1d-1 and 1d-2 are arranged in a state where the short sides 1e are in close contact with each other.
When the tip side short side 1e of the unit single plate 1d-2 is detected by the fourth detector 6, the coating roll 43a and the doctor roll 43b of the spreader 43 are moved by the signal from the controller 95 that has received the signal. The lowering is stopped at the application position shown in FIG.

また一方これら作動でも、搬送される単位単板１ｄ−２の、終端側短辺１ｅが前記支持バー１９の箇所を通過し終えると、制御器９５から出される信号により、移動・反転装置１１の待機位置への移動待機、ピストンロッド３１ａの前進位置への突出を行い、次いで縦矧装置３を作動させて単板１を順次接合する。   On the other hand, even in these operations, when the terminal-side short side 1e of the unit single plate 1d-2 to be conveyed has passed through the place of the support bar 19, the signal from the controller 95 causes the movement / reversing device 11 to The stand-by movement to the stand-by position and the protrusion of the piston rod 31a to the advance position are performed, and then the downboard device 3 is operated to sequentially join the single plates 1.

尚、これ以降、前記のように先行の単位単板の終端側短辺が該支持バー１９の箇所を通過し終えるために十分な時間が経過すると、後続の単位単板を作成し且つ該単位単板を移動・反転装置１１で１枚づつ搬送可能となる位置、即ち図１、図２に示す１ｄ−１と同様の位置に待機させるべく、次のように各部材を作動させる。
前記１ｄ−２の場合と同様に、縦矧装置３を作動させて単板を接合し、該接合された単板の傾斜辺１ｃが第２検知器２ｂに検知されると、同様の作動で第１丸鋸７により切断して単位単板とする。またこの単位単板は、エアシリンダ２１が後退作動し移動・反転装置１１が待機位置に復帰している時、ロール９を走行させ、第３検知器４に単位単板が検知されると該ロール９の走行を停止させ、待機させる。 After that, when a sufficient time has passed so that the terminal side short side of the preceding unit single plate passes through the portion of the support bar 19 as described above, the subsequent unit single plate is formed and the unit Each member is operated as follows in order to wait at a position where the single plate can be conveyed one by one by the moving / reversing device 11, that is, the same position as 1d-1 shown in FIGS.
Similarly to the case of 1d-2, the vertical saddle device 3 is operated to join the single plates, and when the inclined side 1c of the joined single plate is detected by the second detector 2b, the same operation is performed. A unit single plate is cut by the first circular saw 7. Further, when the unit cylinder is detected by the third detector 4, the unit single plate is moved when the air cylinder 21 is moved backward and the moving / reversing device 11 is returned to the standby position. The traveling of the roll 9 is stopped and put on standby.

そこで前記単位単板１ｄ−２に続いて同様に、単位単板１ｄ−３が形成され、同じく第３検知器４により検知されることで、図２に示す１ｄ−１と同様の位置で停止待機させられる。   Therefore, the unit single plate 1d-3 is formed similarly to the unit single plate 1d-2, and is similarly detected by the third detector 4, so that it stops at the same position as 1d-1 shown in FIG. It is made to wait.

次いで、図５の二点鎖線で示した場合と同様に、回動バー３７と第１基体３５との間で単位単板１ｄ−３を挟持した後、エアシリンダ３１のピストンロッド３１ａを中間位置まで後退作動させる。
次に制御器９５から出される信号によりモータ２３を作動させ、図５と対応する側面説明図である図２３に示すように、第１回転軸１３を反時計回りに１８０度回転させる。
そこで、単位単板１ｄ−３は便宜上二点鎖線で示すロール４１の若干上方に、位置することになる。 Next, similarly to the case indicated by the two-dot chain line in FIG. 5, after the unit single plate 1 d-3 is sandwiched between the rotation bar 37 and the first base 35, the piston rod 31 a of the air cylinder 31 is moved to the intermediate position. Operate backward until
Next, the motor 23 is actuated by a signal output from the controller 95, and the first rotating shaft 13 is rotated 180 degrees counterclockwise as shown in FIG. 23, which is an explanatory side view corresponding to FIG.
Therefore, the unit single plate 1d-3 is positioned slightly above the roll 41 indicated by a two-dot chain line for convenience.

次いでエアシリンダ３１を作動させピストンロッド３１ａを前進位置まで移動させると、図２４に示すように第１回転軸１３が下降し、単位単板１ｄ−３がロール４１に当たる。
次に、エアシリンダ３９を作動させピストンロッド３９ａを後退位置まで移動させて図２５に示すように回動バー３７を矢印方向に回動させ、前記単位単板１ｄ−３の挟持を開放する。
次いでエアシリンダ３１を作動させピストンロッド３１ａを後退位置まで移動させると、図２６に示すように第１回転軸１３が上昇し、単位単板１ｄ−３はロール４１だけに接触し支持された状態となる。尚、この場合、ロール４１上の単位単板１ｄ−３は、後述する図２７で示すように、単位単板１ｄ−１、１ｄ−２と、ロール４１の搬送方向と平行な仮想線に対し線対称な状態となっている。 Next, when the air cylinder 31 is operated and the piston rod 31a is moved to the forward position, the first rotating shaft 13 is lowered as shown in FIG. 24, and the unit single plate 1d-3 hits the roll 41.
Next, the air cylinder 39 is actuated to move the piston rod 39a to the retracted position, and the rotating bar 37 is rotated in the direction of the arrow as shown in FIG. 25 to release the unit single plate 1d-3.
Next, when the air cylinder 31 is operated and the piston rod 31a is moved to the retracted position, the first rotating shaft 13 is lifted as shown in FIG. 26, and the unit single plate 1d-3 is in contact with and supported by only the roll 41. It becomes. In this case, the unit single plate 1d-3 on the roll 41 is in relation to the unit single plates 1d-1, 1d-2 and a virtual line parallel to the transport direction of the roll 41 as shown in FIG. It is in a line-symmetric state.

次に、先の単位単板１ｄ−２を図２２に示す状態に並べ且つ各吸着バー６５ａ，６５ｂ、６７ａ，６７ｂ、６９ａ、は、元の位置に戻っていることを条件として、制御器９５から信号が出され、ロール４１、ロール４５を走行させる。
そこで単位単板１ｄ−３はスプレッダ４３の箇所を通るが、スプレッダ４３が図７のように配置されているので、単位単板１ｄ−３の上面に接着剤が塗布される。
更にロール４５で搬送され、第４検知器６によりその先端側短辺１ｅが検出されるとロール４５が停止し、図２７に示す状態に、単位単板１ｄ−３が位置する。 Next, the controller 95 is arranged on the condition that the previous unit single plates 1d-2 are arranged in the state shown in FIG. 22 and the respective suction bars 65a, 65b, 67a, 67b, 69a are returned to their original positions. A signal is issued from the roll 41 and the roll 41 and the roll 45 are caused to travel.
Therefore, the unit single plate 1d-3 passes through the place of the spreader 43. Since the spreader 43 is arranged as shown in FIG. 7, an adhesive is applied to the upper surface of the unit single plate 1d-3.
Further, the roll 45 is transported by the roll 45, and when the leading edge side short side 1e is detected by the fourth detector 6, the roll 45 stops and the unit single plate 1d-3 is positioned in the state shown in FIG.

次いで単位単板１ｄ−１、１ｄ−２の場合と同様に、第２回転軸５１を上昇させ、これに設けられている各吸着バーも上昇し図１７に示した場合と同様に、単位単板１ｄ−１は、各吸着カップ７１により支持されて持ち上げられ、ロール４５から離れる。
次いで制御器９５から出される信号により、バキューム装置（図示せず）から単位単板１ｄ−３に対応する吸着バー６７ａ，６９ａ、及び６７ｂの各吸着カップ７１に通じるに各開閉弁を開作動させて、単位単板１ｄ−１を吸着保持する。
次に図２８に示すようにモータ５５により第２回転軸５１を反時計回りに９０度回転させた後に停止させ、単位単板１ｄ−３を垂直な状態として支持しておく。 Next, as in the case of the unit single plates 1d-1, 1d-2, the second rotating shaft 51 is raised, and the respective suction bars provided on the second rotating shaft 51 are also raised, as in the case shown in FIG. The plate 1 d-1 is supported and lifted by the suction cups 71 and is separated from the roll 45.
Next, in response to a signal output from the controller 95, each on-off valve is opened to communicate with each suction cup 71 of the suction bars 67a, 69a, and 67b corresponding to the unit single plate 1d-3 from a vacuum device (not shown). The unit single plate 1d-1 is sucked and held.
Next, as shown in FIG. 28, the second rotating shaft 51 is rotated 90 degrees counterclockwise by the motor 55 and then stopped to support the unit single plate 1d-3 in a vertical state.

次いで便宜上図２７で説明すると、単位単板１ｄ−３の角部９７と単位単板１ｄ−１の角部９９とが、ロール４５の搬送方向と直交する方向で同一仮想線上に位置する箇所まで、サーボモータ（図示せず）を作動させて搬送・反転装置４７をロール４５の搬送方向へ移動させ停止させる。
次にモータ５５により第２回転軸５１を前記反時計回りに更に９０度回転させた後に停止させ、以後、単位単板１ｄ−１の場合と同様に、作動させて単位単板１ｄ−３を載置し、各吸着バーでの吸着を中止する。
その結果、図２９に示すようにチェーンコンベア７５上にある単位単板１ｄ−１及び単位単板１ｄ−２に跨った状態で且つ該角部９７と角部９９とが一致した状態で、単位単板１ｄ−３が接着剤を塗布された面を下側として重ね合わされる。 Next, for convenience, FIG. 27 illustrates that the corner 97 of the unit single plate 1d-3 and the corner 99 of the unit single plate 1d-1 are located on the same imaginary line in the direction orthogonal to the transport direction of the roll 45. Then, a servo motor (not shown) is operated to move the transport / reverse device 47 in the transport direction of the roll 45 and stop it.
Next, the second rotating shaft 51 is further rotated 90 degrees counterclockwise by the motor 55 and then stopped, and thereafter the unit single plate 1d-3 is operated in the same manner as in the case of the unit single plate 1d-1. Place and stop the suction at each suction bar.
As a result, as shown in FIG. 29, the unit is in a state where it straddles the unit veneer 1d-1 and the unit veneer 1d-2 on the chain conveyor 75 and the corner 97 and the corner 99 coincide with each other. The veneer 1d-3 is overlaid with the surface coated with the adhesive as the lower side.

該載置後、エアシリンダ６３を作動させて第２回転軸５１を上昇させ単位単板１ｄ−３から各吸着カップを離し、次いでモータ５５により第２回転軸５１を前記とは逆の時計回りに９０度回転させた後に停止させ、次にサーボモータ（図示せず）を作動させて搬送・反転装置４７を、前記とは逆方向に移動させ最初に待機していた位置に至ると、停止させる。
次にモータ５５により第２回転軸５１を同じく時計回りに９０度回転させ、前記初期状態で停止待機させる。 After the placement, the air cylinder 63 is operated to raise the second rotating shaft 51 to release each suction cup from the unit single plate 1d-3, and then the motor 55 moves the second rotating shaft 51 in the clockwise direction opposite to the above. After rotating 90 degrees, the servo motor (not shown) is actuated to move the conveying / reversing device 47 in the opposite direction to the position where it was initially waiting. Let
Next, the second rotating shaft 51 is similarly rotated 90 degrees clockwise by the motor 55, and stopped in the initial state.

一方これら作動でも、搬送される単位単板１ｄ−３の終端側短辺１ｅが前記支持バー１９の箇所を通過し終えると、制御器９５から出される信号により、モータ２３を作動させて第１回転軸１３を前記とは逆の時計回りに１８０度回転させた後、エアシリンダ３１のピストンロッド３１ａを前進位置へ移動させ待機させておく。次いで縦矧装置３を作動させて単板１の接合を再開し、前記と同様の作動で、後続の単位単板１ｄ−４を形成し、ロール９により搬送して第３検知器４によりその傾斜辺１ｃが検出された信号が出されると、ロール９を停止させる。
以後は、単位単板１ｄ−１，２の場合と同じ作動で、単位単板１ｄ−４を反転させないでロール４１上に乗せ、次いでロール４１、ロール４５を走行させて単位単板１ｄ−４の先端側短辺１ｅが第４検知器６に検知されると、ロール４１、ロール４５を停止させ、図３０の状態とする。
ここでスプレッダ４３は、図７の位置に設定されたままであるので、スプレッダ４３を通過した単位単板１ｄ−４の上面には接着剤が塗布される。 On the other hand, even in these operations, when the terminal-side short side 1e of the unit veneer 1d-3 to be conveyed has passed through the portion of the support bar 19, the motor 23 is operated by the signal output from the controller 95 to operate the first. After rotating the rotation shaft 13 by 180 degrees in the clockwise direction opposite to the above, the piston rod 31a of the air cylinder 31 is moved to the forward movement position and waits. Next, the vertical unit 3 is operated to restart the joining of the single plates 1. By the same operation as described above, the subsequent unit single plate 1 d-4 is formed, conveyed by the roll 9, and then the third detector 4. When a signal in which the inclined side 1c is detected is output, the roll 9 is stopped.
Thereafter, the unit single plate 1d-4 is placed on the roll 41 without being inverted by the same operation as that of the unit single plate 1d-1 and 2, and then the roll 41 and the roll 45 are run to move the unit single plate 1d-4. When the distal end side short side 1e is detected by the fourth detector 6, the roll 41 and the roll 45 are stopped, and the state shown in FIG. 30 is obtained.
Here, since the spreader 43 remains set at the position of FIG. 7, an adhesive is applied to the upper surface of the unit single plate 1 d-4 that has passed through the spreader 43.

尚、単位単板１ｄ−４に続く各単位単板は、後述するように、連続する２枚の単位単板（例えば後述する単位単板１ｄ−５，６）は移動・反転装置１１で水平移動をさせ、続く１枚の単位単板（例えば後述する単位単板１ｄ−７）は移動・反転装置１１で反転移動をさせ、更に続く連続する２枚の単位単板（例えば後述する単位単板１ｄ−８，９）は同じく水平移動をさせと、これら動作を順次繰り返すように、制御器９５からの信号で移動・反転装置１１の作動が制御される。
また、スプレッダ４３による接着剤の塗付は、前記単位単板１ｄ−３及び単位単板１ｄ−４と連続して２枚の単位単板には接着剤を塗付し、続く１枚の単位単板、即ち後述する単位単板１ｄ−５には接着剤を塗布せず、更に続く２枚の単位単板以（例えば後述する単位単板１ｄ−６、１ｄ−７）には接着剤を塗付しと、これら動作を順次繰り返すように、制御器９５からの信号で、塗布ロール４３ａ及びドクターロール４３ｂの上下動が制御される。 Note that each unit single plate following the unit single plate 1d-4 is, as will be described later, two consecutive unit single plates (for example, unit single plates 1d-5, 6 described later) horizontally by the moving / reversing device 11. The following unit single plate (for example, unit single plate 1d-7 to be described later) is reversed by the moving / reversing device 11 and further continued two unit single plates (for example, unit single units to be described later). When the plates 1d-8, 9) are similarly moved horizontally, the operation of the moving / reversing device 11 is controlled by a signal from the controller 95 so that these operations are repeated in sequence.
In addition, the spreader 43 is applied with the adhesive by applying the adhesive to the two unit single plates in succession to the unit single plate 1d-3 and the unit single plate 1d-4, and then one unit. Adhesive is not applied to a single plate, that is, a unit single plate 1d-5 described later, and an adhesive is applied to two or more subsequent unit single plates (for example, unit single plates 1d-6, 1d-7 described later). The application roll 43a and the doctor roll 43b are controlled to move up and down by a signal from the controller 95 so that the application and the operations are sequentially repeated.

次いで、単位単板１ｄ−３の場合と同じ作動で、吸着カップ７１により単位単板１ｄ−４を吸着保持し、図２８に示した場合と同様に、第２回転軸５１を反時計回りに９０度回転させた後に停止させ、単位単板１ｄ−４を垂直な状態として支持する。
次に便宜上、図３０で説明すると、単位単板１ｄ−４の角部１０１と単位単板１ｄ−１の角部９９とが、ロール４５の搬送方向と直交する方向で同一仮想線上に位置する箇所まで、サーボモータ（図示せず）を作動させて搬送・反転装置４７をロール４５の搬送方向へ移動させ停止させる。
次にモータ５５により第２回転軸５１を前記反時計回りに更に９０度回転させた後に停止させ、以後、単位単板１ｄ−１の場合と同様に作動させて単位単板１ｄ−４を載置し、各吸着バーでの吸着を中止する。
その結果図３１に示すように単位単板１ｄ−４は、接着剤を塗布された面を下側として、単位単板１ｄ−１に相対する位置で該角部１０１と角部９９とが一致した状態で、単位単板１ｄ−１と単位単板１ｄ−３に跨った状態で重ね合わされている。 Next, the unit single plate 1d-4 is sucked and held by the suction cup 71 by the same operation as that of the unit single plate 1d-3, and the second rotating shaft 51 is rotated counterclockwise as in the case shown in FIG. The unit single plate 1d-4 is stopped after being rotated by 90 degrees and supported in a vertical state.
Next, for convenience, with reference to FIG. 30, the corner portion 101 of the unit single plate 1 d-4 and the corner portion 99 of the unit single plate 1 d-1 are located on the same imaginary line in a direction orthogonal to the conveyance direction of the roll 45. A servo motor (not shown) is actuated to a position to move the transport / reversing device 47 in the transport direction of the roll 45 and stop it.
Next, the second rotating shaft 51 is further rotated 90 degrees counterclockwise by the motor 55 and then stopped. Thereafter, the unit single plate 1d-4 is mounted by operating in the same manner as the unit single plate 1d-1. And stop adsorption at each adsorption bar.
As a result, as shown in FIG. 31, in the unit single plate 1d-4, the corner 101 and the corner 99 coincide with each other at a position facing the unit single plate 1d-1 with the surface coated with the adhesive on the lower side. In this state, the unit single plate 1d-1 and the unit single plate 1d-3 are overlapped with each other.

該載置後、エアシリンダ６３を作動させて第２回転軸５１を上昇させ単位単板１ｄ−４から各吸着カップを離し、次いでモータ５５により第２回転軸５１を前記とは逆の時計回りに９０度回転させた後に停止させ、次にサーボモータ（図示せず）を作動させて搬送・反転装置４７を、前記とは逆方向に移動させ最初に待機していた位置に至ると、停止させる。
次にモータ５５により第２回転軸５１を同じく時計回りに９０度回転させ、図３１に示す前記初期状態で停止待機させる。 After the mounting, the air cylinder 63 is operated to raise the second rotating shaft 51 to release each suction cup from the unit single plate 1d-4, and then the motor 55 moves the second rotating shaft 51 in the clockwise direction opposite to the above. After rotating 90 degrees, the servo motor (not shown) is actuated to move the conveying / reversing device 47 in the opposite direction to the position where it was initially waiting. Let
Next, the second rotating shaft 51 is similarly rotated 90 degrees clockwise by the motor 55, and is stopped and waited in the initial state shown in FIG.

一方これら作動でも、搬送される単位単板１ｄ−４の終端側短辺１ｅが前記支持バー１９の箇所を通過し終えると、制御器９５から出される信号により、モータ２３を作動させて第１回転軸１３を前記とは逆の時計回りに１８０度回転させた後、エアシリンダ３１のピストンロッド３１ａを前進位置へ移動させ待機させておく。また同じく制御器９５から出される信号により、スプレッダ４３の塗布ロール４３ａ及びドクターロール４３ｂを図６で示す位置に上昇待機させておく。
次いで縦矧装置３を作動させて単板１の接合を再開し、前記と同様の作動で、後続の単位単板１ｄ−５を形成し、ロール９により搬送して第３検知器４によりその傾斜辺１ｃが検出された信号が出されると、ロール９を停止させる。
以後は、単位単板１ｄ−１の場合と同じ作動で、単位単板１ｄ−５を第１基体３５と回動バー３７とにより挟持した後、第１回転軸１３は回転させずエアシリンダ２１を作動させて単位単板１ｄ−５をロール４１上に乗せる。
次いでロール４１、ロール４５を走行させて単位単板１ｄ−５の先端側短辺１ｅが第４検知器６に検知されると、ロール４１、ロール４５を停止させ、図１０の単位単板１ｄ−１と同じ位置関係とする。
尚、スプレッダ４３は前記のように設定されているので、単位単板１ｄ−５には接着剤が塗布されない。 On the other hand, even in these operations, when the terminal-side short side 1e of the unit veneer 1d-4 to be conveyed has passed through the place of the support bar 19, the motor 23 is operated by the signal output from the controller 95 to operate the first. After rotating the rotation shaft 13 by 180 degrees in the clockwise direction opposite to the above, the piston rod 31a of the air cylinder 31 is moved to the forward movement position and waits. Similarly, the application roll 43a and the doctor roll 43b of the spreader 43 are made to stand up and wait at the positions shown in FIG.
Next, the vertical unit 3 is operated to restart the joining of the single plates 1, and the subsequent unit single plate 1 d-5 is formed by the same operation as described above, and is conveyed by the roll 9 and is then detected by the third detector 4. When a signal in which the inclined side 1c is detected is output, the roll 9 is stopped.
Thereafter, the unit single plate 1d-5 is sandwiched between the first base 35 and the rotation bar 37 by the same operation as that of the unit single plate 1d-1, and then the first rotating shaft 13 is not rotated and the air cylinder 21 is rotated. Is operated to place the unit single plate 1d-5 on the roll 41.
Next, when the roll 41 and the roll 45 are run and the tip side short side 1e of the unit single plate 1d-5 is detected by the fourth detector 6, the roll 41 and the roll 45 are stopped, and the unit single plate 1d of FIG. The same positional relationship as -1.
Since the spreader 43 is set as described above, no adhesive is applied to the unit single plate 1d-5.

一方前記単位単板１ｄ−４を図３１に示すように重ね合せ、単位単板１ｄ−４から各吸着カップが離れた後、制御器９５から出される信号により、前記重ね合わされた４枚の単板群をチェーンコンベア７５により後述の所定量だけ移動させ停止させる。
該所定量は、１枚の単位単板のチェーンコンベア７５の走行方向長さ、即ち図３１で示す単位単板１ｄ−４の長さＬである。
チェーンコンベア７５の該長さＬ移動、停止により、重ね合わされた単位単板１ｄ−４等の一部が、コールドプレス７７の両プレス７９及び８５の間に入るが、該入った部分は、単位単板の厚さ方向で３枚揃っていない箇所があるため、制御器９５から上側プレス８５を作動させる信号が出ず、両プレスによる圧接は行わない。 On the other hand, the unit single plates 1d-4 are overlapped as shown in FIG. 31, and after the suction cups are separated from the unit single plate 1d-4, the four single units overlapped by a signal output from the controller 95 are obtained. The plate group is moved by the chain conveyor 75 by a predetermined amount described later and stopped.
The predetermined amount is the length in the running direction of the chain conveyor 75 of one unit single plate, that is, the length L of the unit single plate 1d-4 shown in FIG.
Due to the movement and stoppage of the length L of the chain conveyor 75, a part of the unit single plate 1d-4 and the like overlapped enters between the presses 79 and 85 of the cold press 77. Since there are places where three sheets are not aligned in the thickness direction of the single plate, a signal for operating the upper press 85 is not output from the controller 95, and the press contact by both presses is not performed.

また単位単板１ｄ−５は、単位単板１ｄ−３の場合と同様に、各吸着バーにより吸着保持した後、同じく図２８に示したように垂直な状態として支持する。
次に、図３２に示した状態で単位単板１ｄ−２の矢印で示す角部１０３に対し、単位単板１ｄ−５が前記第４検知器６に検知され停止した時の矢印で示す角部１０１が、ロール４５の搬送方向と直交する方向で同一仮想線上に位置するように、単位単板１ｄ−３の場合と同様に、搬送・反転装置４７をロール４５の搬送方向へ移動させ停止させる。
次いで前記状態で各吸着バーを更に回動させ、単位単板１ｄ−５を、該角部１０１と角部１０３とが一致し、且つ単位単板１ｄ−２と単位単板１ｄ−５との相対する短辺同士が密接した状態で、図３３に示すようにチェーンコンベア７５上に載置し、各吸着バーでの吸着を中止する。
前記単位単板１ｄ−５を載置する動作と平行して、他の単位単板と同様に形成した単位単板１ｄ−６を、単位単板１ｄ−３の場合と同様に、移動・反転装置１１により反転させ、その後、搬送してスプレッダ４３によりその上面への接着剤塗付を行い、その短辺１ｅが第４検知器６により検知されることにより図３４に示す位置で停止待機させる。 Similarly to the unit single plate 1d-3, the unit single plate 1d-5 is sucked and held by each suction bar, and then supported in a vertical state as shown in FIG.
Next, with respect to the corner 103 indicated by the arrow of the unit single plate 1d-2 in the state shown in FIG. 32, the angle indicated by the arrow when the unit single plate 1d-5 is detected by the fourth detector 6 and stopped. As in the case of the unit single plate 1d-3, the conveyance / reversing device 47 is moved in the conveyance direction of the roll 45 and stopped so that the unit 101 is positioned on the same imaginary line in a direction orthogonal to the conveyance direction of the roll 45. Let
Next, each suction bar is further rotated in the above state, and the unit single plate 1d-5 is aligned with the corner portion 101 and the corner portion 103, and between the unit single plate 1d-2 and the unit single plate 1d-5. In a state where the opposing short sides are in close contact with each other, it is placed on the chain conveyor 75 as shown in FIG. 33, and the suction at each suction bar is stopped.
In parallel with the operation of placing the unit single plate 1d-5, the unit single plate 1d-6 formed in the same manner as the other unit single plate is moved and reversed as in the case of the unit single plate 1d-3. Inverted by the apparatus 11, and then transported and applied with an adhesive on its upper surface by the spreader 43, and when the short side 1 e is detected by the fourth detector 6, it stops and waits at the position shown in FIG. 34. .

次いで単位単板１ｄ−６に対応した吸着カップ７１により吸着保持した後、図２８に示した場合と同様に、各吸着バーの回動により単位単板１ｄ−６を垂直な状態として支持する。次に図３４において、単位単板１ｄ−６の矢印で示す角部１０５が、単位単板１ｄ−２の矢印で示す角部１０７と、ロール４５の搬送方向と直交する方向で同一仮想線上に位置するように、搬送・反転装置４７を移動させてから停止させておく。
前記状態で各吸着バーを更に回動させ、単位単板１ｄ−６を、単位単板１ｄ−６の角部１０５と角部１０７とが一致し、且つ単位単板１ｄ−３と単位単板１ｄ−６との相対する短辺同士が密接した状態で、図３５に示すように、単位単板１ｄ−２から単位単板１ｄ−５に跨った状態で載置する。 Next, after being sucked and held by the suction cup 71 corresponding to the unit single plate 1d-6, the unit single plate 1d-6 is supported in a vertical state by the rotation of each suction bar as in the case shown in FIG. Next, in FIG. 34, the corner portion 105 indicated by the arrow of the unit single plate 1d-6 is on the same imaginary line in the direction perpendicular to the conveyance direction of the roll 45 with the corner portion 107 indicated by the arrow of the unit single plate 1d-2. The conveying / reversing device 47 is moved so as to be positioned and then stopped.
In this state, each suction bar is further rotated, and the unit single plate 1d-6 is aligned with the corner 105 and the corner 107 of the unit single plate 1d-6, and the unit single plate 1d-3 and the unit single plate are aligned. As shown in FIG. 35, the short sides opposed to 1d-6 are placed in close contact with each other, from the unit single plate 1d-2 to the unit single plate 1d-5.

次いで単位単板１ｄ−４の場合と同様に、第１丸鋸７での切断、移動・反転装置１１での水平移動、スプレッダ４３による接着剤の塗付を経て搬送される単位単板１ｄ−７の短辺１ｅが、第４検知器６により検知されることにより、図３６で示す位置で停止待機させられる。
次に、同様に吸着カップ７１により吸着保持し、図２８に示した場合と同様に、各吸着バーの回動により単位単板１ｄ−７を垂直な状態として支持した後、図３６で示す単位単板１ｄ−７の矢印で示す角部１０９が、単位単板１ｄ−６の矢印で示す角部１１１と、ロール４５の搬送方向と直交する方向で同一仮想線上に位置するように、搬送・反転装置４７を走行させる。 Next, as in the case of the unit single plate 1d-4, the unit single plate 1d- which is conveyed after being cut by the first circular saw 7, horizontally moved by the moving / reversing device 11, and coated with an adhesive by the spreader 43. The short side 1e of 7 is detected by the fourth detector 6 to be stopped at the position shown in FIG.
Next, similarly, the suction cup 71 holds and holds the unit single plate 1d-7 in a vertical state by rotating each suction bar, and then the unit shown in FIG. The corner 109 indicated by the arrow of the single plate 1d-7 is positioned on the same imaginary line in the direction perpendicular to the conveyance direction of the roll 45 with the corner 111 indicated by the arrow of the unit single plate 1d-6. The reversing device 47 is caused to travel.

次いで前記状態で各吸着バーを更に回動させ、単位単板１ｄ−７を、該角部１０９と角部１１１とが一致し、且つ単位単板１ｄ−４と単位単板１ｄ−７との相対する短辺同士が密接した状態で、図３７に示すようにチェーンコンベア７５上に載置し、各吸着バーでの吸着を中止する。   Next, each suction bar is further rotated in the above state, and the unit single plate 1d-7 is aligned between the corner 109 and the corner 111, and the unit single plate 1d-4 and the unit single plate 1d-7 are aligned. In a state where the opposing short sides are in close contact with each other, it is placed on the chain conveyor 75 as shown in FIG. 37, and the suction at each suction bar is stopped.

次に、チェーンコンベア７５の長さＬの走行停止により、図３７の状態から図３８の状態とし、また接着剤が塗布されていない単位単板１ｄ−８の短辺１ｅが第４検知器６に検知されて、図３２の単位単板１ｄ−５と同様に図３８の位置で停止待機させられる。
尚、チェーンコンベア７５の走行停止により、単位単板１ｄ−７の一部までが、コールドプレス７７の下側プレス７９及び上側プレス８５の間に入る。該入った部分の殆どの部分が、単位単板の厚さ方向で３枚揃っている。
そこでチェーンコンベア７５が停止した後、上側プレス８５を下降させ、所定圧力で下側プレス７９及び上側プレス８５の間にある各単位単板を少なくとも所定時間、圧接し続ける。この圧接し続けることで、接着剤の粘着力により該各単位単板が一体化される。 Next, when the chain conveyor 75 is stopped for the length L, the state shown in FIG. 37 is changed to the state shown in FIG. 38, and the short side 1e of the unit single plate 1d-8 to which the adhesive is not applied is the fourth detector 6. In the same way as the unit single plate 1d-5 in FIG.
When the chain conveyor 75 is stopped, a part of the unit single plate 1d-7 enters between the lower press 79 and the upper press 85 of the cold press 77. Almost all of the inserted portions are aligned in the thickness direction of the unit single plate.
Therefore, after the chain conveyor 75 stops, the upper press 85 is lowered, and the unit single plates between the lower press 79 and the upper press 85 are kept in pressure contact with each other for a predetermined time at a predetermined pressure. By continuing the pressure contact, the unit single plates are integrated by the adhesive force of the adhesive.

次いで単位単板１ｄ−８を、図３３における単位単板１ｄ−５と同様の作動で、チェーンコンベア７５上で単板１ｄ−５との相対する短辺同士が密接した状態に載置し、図３９の状態とする。
次に後続の単位単板１ｄ−９の短辺１ｅが、図４０に示すように第４検知器６に検知されて停止待機させられる。
この単位単板１ｄ−９を、図３４における単位単板１ｄ−６と同様の動作で、図４１に示すように、図４０での単位単板１ｄ−９の矢印で示す角部１１７が、単位単板１ｄ−５の矢印で示す角部１１９とが一致し且つ単位単板１ｄ−６と相対する短辺同士が密接した状態に載置する。 Next, the unit single plate 1d-8 is placed in a state in which the short sides facing the single plate 1d-5 are in close contact with each other on the chain conveyor 75 by the same operation as the unit single plate 1d-5 in FIG. The state shown in FIG. 39 is assumed.
Next, the short side 1e of the subsequent unit single plate 1d-9 is detected by the fourth detector 6 as shown in FIG.
The unit single plate 1d-9 is operated in the same manner as the unit single plate 1d-6 in FIG. 34. As shown in FIG. 41, the corner portion 117 indicated by the arrow of the unit single plate 1d-9 in FIG. The unit single plate 1d-5 is placed in a state where the corners 119 indicated by the arrows coincide with each other and the short sides facing the unit single plate 1d-6 are in close contact with each other.

次いで後続の単位単板１ｄ−１０の短辺１ｅが、図４２に示すように第４検知器６に検知されて停止待機させられる。この単位単板１ｄ−１０を、図３６における単位単板１ｄ−７と同様の動作で、図４３に示すように、図４２での単位単板１ｄ−１０の矢印で示す角部１２１と、単位単板１ｄ−９の矢印で示す角部１１９とが一致し且つ単位単板１ｄ−７と相対する短辺同士が密接した状態に載置する。
尚、コールドプレス７７による前記圧接が所定時間経過した後であって、しかも単位単板１ｄ−１０の短辺１ｅが第４検知器６に検知されると、前記継続していたコールドプレス７７による前記圧接を中止するべく、上側プレス８５を上昇させ元の位置で待機させておく。 Next, the short side 1e of the subsequent unit single plate 1d-10 is detected by the fourth detector 6 as shown in FIG. The unit single plate 1d-10 is operated in the same manner as the unit single plate 1d-7 in FIG. 36, and as shown in FIG. 43, a corner 121 shown by an arrow of the unit single plate 1d-10 in FIG. The unit single plate 1d-9 is placed in a state where the corners 119 indicated by the arrows coincide with each other and the short sides facing the unit single plate 1d-7 are in close contact with each other.
In addition, after the said press contact by the cold press 77 has passed for a predetermined time, and when the short side 1e of the unit single plate 1d-10 is detected by the 4th detector 6, by the said cold press 77 which continued. In order to stop the press contact, the upper press 85 is raised and kept in the original position.

また単位単板１ｄ−１０が図４３の状態となると、チェーンコンベア７５を長さＬだけ走行し停止させ、各単位単板が図４４に示す位置関係となる。
次いで、コールドプレス７７の上側プレス８５を下降させ、所定圧力で前記と同様に各単位単板を圧接し続ける。 When the unit single plate 1d-10 is in the state shown in FIG. 43, the chain conveyor 75 is run for a length L and stopped, and the unit single plates have the positional relationship shown in FIG.
Next, the upper press 85 of the cold press 77 is lowered, and the unit single plates are kept in pressure contact in the same manner as described above at a predetermined pressure.

一方、各単位単板が図４４に示す位置関係となると、コールドプレス７７の搬出側では、図４５に示すように、重ね合わされた単位単板群がベルト８３及びコンベア８９の上に跨った状態となるが、この時、単位単板１ｄ−４の角部１２３がベルト８３及びコンベア８９の間に位置するように、各々配置しておく。
この状態で、第２丸鋸９１を作動させ、二点鎖線で示す位置で重ね合わされた単位単板群を切断する。尚、切断された単位単板群の先端側の部分は手作業で取り除いておく。 On the other hand, when the unit veneers have the positional relationship shown in FIG. 44, on the carry-out side of the cold press 77, as shown in FIG. However, at this time, each unit single plate 1 d-4 is arranged so that the corner 123 is positioned between the belt 83 and the conveyor 89.
In this state, the second circular saw 91 is operated to cut the unit single plate group overlapped at the position indicated by the two-dot chain line. In addition, the part at the front end side of the cut unit single plate group is manually removed.

以後、順次ロール４５で搬送されてくる単位単板は３枚を１組とし、次に示す工程を繰り返して同様に重ね合せるのである。
即ち、最初に搬送されてくる単位単板は図３８で示した単位単板１ｄ−８と、二番目に搬送されてくる単位単板は図４０で示した単位単板１ｄ−９と、三番目に搬送されてくる単位単板は図４２で示した単位単板１ｄ−１０と同様の工程を経て、接着剤塗布の有無及び平面説明図である図３８、図４０及び図４２での短辺１ｅの傾斜方向を同じ状態として搬送する。 Thereafter, the unit single plates sequentially conveyed by the roll 45 are made into a set of three sheets, and the following steps are repeated and overlapped in the same manner.
That is, the unit single plate conveyed first is the unit single plate 1d-8 shown in FIG. 38, the unit single plate conveyed second is the unit single plate 1d-9 shown in FIG. The unit veneer conveyed next undergoes the same steps as the unit veneer 1d-10 shown in FIG. 42, and the presence / absence of application of the adhesive and the plan view of FIG. 38, FIG. 40 and FIG. The side 1e is conveyed in the same inclination direction.

また順次搬送されるこれら３枚の各単位単板の搬送方向下手側短辺１ｅが第４検知器６により検知されると、該信号を受けた制御器９５からの作動信号により、最初に搬送されてくる単位単板は図３８の単位単板１ｄ−８と、二番目に搬送されてくる単位単板は図４０の単位単板１ｄ−９と、三番目に搬送されてくる単位単板は図４２の単位単板１ｄ−１０と同じように各部材を作動させて、各々チェーンコンベア７５上又は載置済みの単位単板上に載置する。
次いで、３枚の各単位単板が重ね合わされる毎に、即ち重ね合わされた単位単板が図４３に示した場合と同じ位置関係となる毎に、コールドプレス７７の上側プレス８５を上昇させ圧接を中止し、次にチェーンコンベア７５を長さＬだけ走行停止させ、更に上側プレス８５を下降させ、所定圧力で前記と同様に各単位単板を圧接する各動作を行う。
更には、図４５の状態から、最初にチェーンコンベア７５が長さＬだけ走行し停止すると、コールドプレス７７の搬出側では、図４６に示すように、重ね合わされた単位単板群がベルト８３及びコンベア８９の上に跨った状態となっている。
そこで図４５を用いて説明した場合と同様に、第２丸鋸９１を往復作動させ、二点鎖線の位置で単位単板群を切断する。
この切断で得られた長手方向が長さＬの単位単板群（以下、定尺単位単板群という）は、その全体で厚さ方向に３枚の単位単板が揃っており製品となるもので、手作業又は公知の堆積装置により堆積装置９３上に堆積する。
以後、チェーンコンベア７５が長さＬだけ走行し停止する毎に、第２丸鋸９１を往復作動させ、得られた定尺単位単板群を順次堆積装置９３上に堆積する。
またこのようにして堆積された定尺単位単板群は、更に別に設けたコールドプレス（図示せず）により所定時間圧接した後、通常合板製造で用いるホットプレスにより加熱加圧して接着し、斜行合板とする。 Further, when the fourth detector 6 detects the lower short side 1e in the transport direction of each of these three unit single plates that are sequentially transported, the first transport is performed by the operation signal from the controller 95 that has received the signal. 38 is the unit single plate 1d-8 in FIG. 38, the second unit single plate is the unit single plate 1d-9 in FIG. 40, and the third single unit plate is transported. 42 operates each member in the same manner as the unit single plate 1d-10 of FIG. 42, and each member is placed on the chain conveyor 75 or on the unit single plate already placed.
Next, every time the three unit single plates are overlaid, that is, every time the overlaid unit single plates have the same positional relationship as shown in FIG. 43, the upper press 85 of the cold press 77 is raised and pressed. Next, the chain conveyor 75 is stopped for the length L, the upper press 85 is further lowered, and each operation of pressing the unit single plates at a predetermined pressure as described above is performed.
45, when the chain conveyor 75 first travels for a length L and stops, on the carry-out side of the cold press 77, as shown in FIG. It is in a state straddling the conveyor 89.
Therefore, similarly to the case described with reference to FIG. 45, the second circular saw 91 is reciprocated to cut the unit single plate group at the position of the two-dot chain line.
The unit single plate group whose longitudinal direction is obtained by this cutting is a product having three unit single plates in the thickness direction as a whole. It is deposited on the deposition device 93 manually or by a known deposition device.
Thereafter, each time the chain conveyor 75 travels for a length L and stops, the second circular saw 91 is reciprocated, and the obtained fixed unit single plate group is sequentially deposited on the deposition device 93.
In addition, the fixed unit single plate group deposited in this manner is further pressed by a cold press (not shown) provided separately for a predetermined time, and then heated and pressed by a hot press normally used in plywood manufacturing, and bonded. A plywood board.

以上のように前記実施例では、搬送・反転装置４７により、選択された単位単板を、繊維方向と傾斜する辺と平行な軸中心線の回りに回転して反転させ、その他の単位単板は反転させず、これら両単位単板を傾斜する辺同士を揃えた状態で接着剤を介して重ね合せることで、斜行状態に効率よく重ね合せ、簡単な構成で斜行合板を製造することができる。   As described above, in the above-described embodiment, the selected unit single plate is rotated by the conveying / reversing device 47 around the axis center line parallel to the side inclined with the fiber direction, and the other unit single plate is rotated. Is not reversed, and these unit single plates are laminated with adhesives in a state where the inclined sides are aligned, so that they can be efficiently stacked in a skew state, and a skew plywood is manufactured with a simple configuration. Can do.

次に本発明の変更例を説明する。
１. 前記実施例では、単位単板を移動・反転装置１１により回転させることにより、繊維方向と傾斜する辺と平行な軸中心線を、単位単板から離れた位置に設定したが、該軸中心線を単位単板内に設定しても良い。
即ち、該傾斜する辺と平行な方向に設けた一対の挟持体により、単位単板を表裏両面より挟持し、次いで該一対の挟持体を、該一対の挟持体の間で且つ該傾斜する辺と平行な軸中心線の回りに回転して反転させるのである。
２. 前記実施例では、同じ厚さの単位単板を、１個の移動・反転装置１１により順次ロール４１上に供給したが、生産性を上げるために以下のように構成しても良い。
即ち、前記移動・反転装置１１は、単に前述の水平移動作用だけを行わせて各単位単板をロール４１上に供給する。
一方、ロール４１を中心として移動・反転装置１１と反対側に、新に、図１に示した縦矧装置３から移動・反転装置１１に至るまでの装置と同じ単位単板供給装置を、ロール４１の搬送方向と平行な仮想線に対し対称で且つロール４１上に同じく単位単板１ｄを供給可能な位置関係で各々配置する。
該対称な状態に配置された単位単板を形成・供給する装置によって、ロール４１上には、平面での各辺での長さは同一であるが、図１でロール４１上に示した単位単板１ｄと、上記平行な仮想線に対し対称な状態、即ち例えば図２７の単位単板１ｄ−３で示した状態の単位単板を、予め定められた順番により供給する。
即ち、例えば前記実施例と同様に３枚の単位単板を重ね合せる場合、前記移動・反転装置１１からは、チェーンコンベア７５上で重ね合わされた場合に、図４３のα及びγのように外側に位置する単位単板を供給し、前記反対側に設けた装置からは、同じく重ね合わされた場合に、図４３のβのように中央に位置する単位単板を供給するようにし、その供給する順番は、前記実施例でα、β、γと重ねた順と同様とする。
この場合、例えば移動・反転装置１１からは比較的厚さが薄い単板を供給し、新たに設けた単位単板供給装置からは、比較的厚さが厚い単板を供給すれば良い。
３．前記実施例では、チェーンコンベア７５の走行する方向と直交する方向の、一方側からのみ搬送・反転装置４７により単位単板をチェーンコンベア７５上に回転させて重ね合せるようにしたが、生産性を向上させるために、次のように攻勢しても良い。
即ち、チェーンコンベア７５を挟んで、搬送・反転装置４７と反対側に搬送・反転装置４７と同様の装置を新たに設け、該他方側からも同様に単位単板をチェーンコンベア７５上に回転させて重ね合せるようにしても良い。この場合、例えば新たに設けた搬送・反転装置からは前記βのように中央に位置する単位単板を供給すれば良い。
４. 前記実施例では、縦矧装置３から移動・反転装置１１を経て搬送・反転装置４７までを一連に配置したが、単位単板を製造する箇所即ち縦矧装置３から第１丸鋸７で切断するまでの単位単板製造工程と、移動・反転装置１１から堆積装置９３までの接着剤塗付・重ね合わせ工程とを分けて設けても良い。
即ち、単位単板製造工程で、予め単位単板を多数枚製造して堆積しておき、これら単位単板を１枚づつ接着剤塗付・重ね合わせ工程に供給するようにすれば良い。
この場合、単位単板製造工程では、原木切削時に生じる裏割が下面側にある単位単板と、該裏割が上面側にある単位単板とを製造しておく。
このように製造された単位単板は、例えば前記実施例では、αの位置に用いられる単位単板は裏割が下面側にある単位単板を、また、γの位置に用いられる単位単板は裏割が上面側にある単位単板を、接着剤塗付・重ね合わせ工程に供給する。
その結果、製造された斜行合板の、表裏に位置する両単位単板の表面には、裏割がなく、美観上等の欠点となることがない。 Next, a modified example of the present invention will be described.
1. In the above embodiment, the unit single plate is rotated by the moving / reversing device 11 so that the axis center line parallel to the fiber direction and the inclined side is set at a position away from the unit single plate. The center line may be set within the unit veneer.
That is, the unit veneer is sandwiched from both the front and back surfaces by a pair of sandwiching bodies provided in a direction parallel to the sloping sides, and then the pair of sandwiching bodies are sandwiched between the pair of sandwiching bodies and the sloping sides. And rotate around the axis center line parallel to the axis.
2. In the above-described embodiment, the unit single plate having the same thickness is sequentially supplied onto the roll 41 by the single moving / reversing device 11, but may be configured as follows in order to increase productivity.
That is, the moving / reversing device 11 supplies each unit single plate onto the roll 41 by performing only the horizontal moving action described above.
On the other hand, on the opposite side to the moving / reversing device 11 with the roll 41 as the center, a unit single plate feeding device that is the same as the device from the downspout device 3 to the moving / reversing device 11 shown in FIG. The unit single plate 1d is arranged on the roll 41 so as to be symmetric with respect to a virtual line parallel to the transport direction 41 and in the same position as the unit single plate 1d.
The unit shown on the roll 41 in FIG. 1 has the same length on each side of the plane on the roll 41 by the apparatus for forming and supplying the unit single plates arranged in the symmetrical state. The single plate 1d and the unit single plate in a state symmetric with respect to the parallel imaginary line, that is, for example, the state shown by the unit single plate 1d-3 in FIG. 27 are supplied in a predetermined order.
That is, for example, in the case where three unit single plates are overlapped as in the above embodiment, the moving / reversing device 11 has an outer side like α and γ in FIG. 43 when overlapped on the chain conveyor 75. The unit single plate located at the center is supplied from the device provided on the opposite side, and the unit single plate located at the center is supplied as shown in FIG. The order is the same as the order in which α, β, and γ are overlapped in the above embodiment.
In this case, for example, a single plate having a relatively small thickness may be supplied from the moving / reversing device 11, and a single plate having a relatively large thickness may be supplied from the newly provided unit single plate supply device.
3. In the above embodiment, the unit veneer is rotated on the chain conveyor 75 by the conveying / reversing device 47 only in one direction orthogonal to the direction in which the chain conveyor 75 travels. In order to improve, you may attack as follows.
That is, a device similar to the transport / reversing device 47 is newly provided on the opposite side of the transport / reversing device 47 across the chain conveyor 75, and the unit single plate is similarly rotated on the chain conveyor 75 from the other side. You may make it overlap. In this case, for example, a unit single plate located at the center may be supplied from the newly provided transport / reversing device as in the case of β.
4. In the above-described embodiment, the downside device 3, the moving / reversing device 11 and the conveying / reversing device 47 are arranged in series, but the unit single plate is manufactured, that is, from the downside device 3 to the first circular saw 7. The unit single plate manufacturing process until the cutting is performed and the adhesive application / superposition process from the moving / reversing device 11 to the deposition device 93 may be provided separately.
That is, in the unit veneer manufacturing process, a large number of unit veneers may be manufactured and deposited in advance, and these unit veneers may be supplied one by one to the adhesive coating / superposition process.
In this case, in the unit veneer manufacturing process, a unit veneer in which the back split generated when cutting the raw wood is on the lower surface side and a unit veneer in which the back split is on the upper surface side are manufactured.
The unit veneer thus manufactured is, for example, in the above-described embodiment, the unit veneer used at the position of α is a unit veneer whose back side is on the lower surface side, and the unit veneer used at the position of γ Supplies the unit veneer with the reverse side on the upper surface side to the adhesive application and superposition process.
