Examples of electric actuators capable of speed and position control include motors, electric cylinders, and linear motors.
As the motor, a servo motor or a stepping motor can be used.
サーボモータを用いれば、吸引の強弱をダンパ67の開き角度を変えて制御したり、最初は吸引を強くし最後は吸引を弱くするような可変制御も容易に行うことができる。
If a servo motor is used, it is possible to easily control the strength of suction by changing the opening angle of the damper 67, or to perform variable control such that the suction is strengthened at the beginning and the suction is weakened at the end.
電動アクチュエータにモータを用いる場合、動力伝達機構は、たとえば次のように構成される。
ダンパ67の基部は回転軸87に取付けられ、その回転軸87にはホイール88が固定されている。
一方、モータ80の出力軸にはホイール81が固定されている。ホイール81と前記ホイール88との間にはチェーンやタイミングベルト等の索条が巻き掛けられている。
このため、モータ80の正転逆転と停止を制御すると、ダンパ67の開-待機-閉なる切換え動作を行わせることができる。 When a motor is used for the electric actuator, the power transmission mechanism is configured as follows, for example.
A base portion of thedamper 67 is attached to a rotating shaft 87, and a wheel 88 is fixed to the rotating shaft 87.
On the other hand, awheel 81 is fixed to the output shaft of the motor 80. Between the wheel 81 and the wheel 88, a rope such as a chain or a timing belt is wound.
Therefore, when the forward / reverse rotation and stop of themotor 80 are controlled, the damper 67 can be switched to open-standby-close.

この場合、開状態あるいは閉状態が維持される時間が従来技術より長くなるので吸引効率が高くなる。 When themotor 80 is used, the opening / closing operation of the damper 67 is accelerated.
In this case, since the time during which the open state or the closed state is maintained is longer than that in the prior art, the suction efficiency is increased.

In this case, since the time during which the open state or the closed state is maintained is longer than that in the prior art, the suction efficiency is increased.
また、モータ80で、回転速度を制御すると、動作途中を早くしても終端速度を遅くすることが可能なので、ダンパ67の開口66a、66bへの衝突速度は小さく、騒音が低減し、損耗も少なくなる。
Further, when the rotational speed is controlled by the motor 80, the terminal speed can be slowed even if the operation is accelerated, so that the collision speed with the openings 66a and 66b of the damper 67 is small, noise is reduced, and wear is also reduced. Less.
さらに、本実施形態においては、ダンパとモータの間が索条で連結されているので、モータの設置場所を任意に選択でき、展開装置全体をコンパクトにできる。なお、図4ではモータ80は流路切換室66の下方に図示しているが、実際には展開装置の内部の任意の場所に設置される。
Furthermore, in the present embodiment, since the damper and the motor are connected by a rope, the installation location of the motor can be arbitrarily selected, and the entire deployment device can be made compact. In FIG. 4, the motor 80 is illustrated below the flow path switching chamber 66, but actually, it is installed at an arbitrary location inside the developing device.
次に、皺取り工程および受渡し工程の詳細を図5~図9に基づき説明する。
(1)図5は伸展チャック40R,40Lで方形状布類Yの両端部を保持し、かつ上縁部Ybを吸着ボックス51と固定部材である押付けバー53との間で挾持している。このとき方形状布類Yは整形ダクト65の前面壁64より前方で吊下げられている。 Next, details of the scraping process and the delivery process will be described with reference to FIGS.
(1) In FIG. 5, the extension chucks 40R and 40L hold both ends of the rectangular cloth Y, and the upper edge Yb is held between thesuction box 51 and the pressing bar 53 as a fixing member. At this time, the rectangular cloth Y is suspended from the front wall 64 of the shaping duct 65 in front.
(1)図5は伸展チャック40R,40Lで方形状布類Yの両端部を保持し、かつ上縁部Ybを吸着ボックス51と固定部材である押付けバー53との間で挾持している。このとき方形状布類Yは整形ダクト65の前面壁64より前方で吊下げられている。 Next, details of the scraping process and the delivery process will be described with reference to FIGS.
(1) In FIG. 5, the extension chucks 40R and 40L hold both ends of the rectangular cloth Y, and the upper edge Yb is held between the
(2)前記(1)の状態で、ダンパ67は開口66aを閉じ開口66bを開いているので、ブロワー62は整形ダクト65内のエアーを吸引している。これに加え図6に示すように、エアー吹付け装置90から方形状布類Yにエアーを噴射させて、方形状布類Yを整形ダクト65内に押し込む。方形状布類の下方部分は整形ダクト65内に吸引されて該ダクト内に入っていこうとするが、さらにエアー吹付け装置90からのエアー噴射による風圧が加わって方形状布類Yの下方部分が整形ダクト65上方に押し込まれる。
(2) In the state (1), the damper 67 closes the opening 66 a and opens the opening 66 b, so that the blower 62 sucks air in the shaping duct 65. In addition, as shown in FIG. 6, air is jetted from the air blowing device 90 onto the rectangular cloth Y, and the rectangular cloth Y is pushed into the shaping duct 65. The lower part of the rectangular cloth Y is sucked into the shaping duct 65 and tries to enter the duct. However, the lower part of the rectangular cloth Y is added with the wind pressure by the air jet from the air blowing device 90. Is pushed above the shaping duct 65.
(3)図7に示すように、方形状布類Yの下方部分は整形ダクト65内に入り込んでいるので、そのままブロワー62でエアー吸引すると、方形状布類Yが下方に引っ張られて、弛みや皺がとれる。これが、皺取り工程である。
(3) As shown in FIG. 7, since the lower part of the rectangular cloth Y enters the shaping duct 65, if the air is sucked by the blower 62 as it is, the rectangular cloth Y is pulled downward and loosened. I can get a habit. This is the wrinkle removal process.
(4)ついで、伸展チャック40R,40Lを解放し、図8に示すように方形状布類Yの上縁部Ybを吸着した吸引ボックス51が後方に移動すると、その方形状布類Yはバキュームコンベア60に接触する。この状態に合わせダンパ67が開口66bを閉じ開口66aを開くと、吸引ダクト61内の空気がブロワ62で吸引され、バキュームコンベア60には負圧が作用する。そうすると、方形状布類Yはバキュームコンベア60の吸引により保持されて、受渡機構50からバキュームコンベア60に乗り移る。
(4) Next, when the extension chucks 40R and 40L are released and the suction box 51 adsorbing the upper edge Yb of the rectangular cloth Y moves backward as shown in FIG. 8, the rectangular cloth Y is vacuumed. Contact the conveyor 60. When the damper 67 closes the opening 66b and opens the opening 66a in accordance with this state, the air in the suction duct 61 is sucked by the blower 62, and a negative pressure acts on the vacuum conveyor 60. Then, the rectangular cloth Y is held by suction of the vacuum conveyor 60 and is transferred from the delivery mechanism 50 to the vacuum conveyor 60.
さらに、図9に示すようにバキュームコンベア60が後方に駆動して、乗り移った方形状布類Yを排出コンベア70に移送する。排出コンベア70は、方形状に展開された方形状布類Yを後方に設置される次工程の処理装置に供給する。
Further, as shown in FIG. 9, the vacuum conveyor 60 is driven rearward, and the transferred square cloth Y is transferred to the discharge conveyor 70. The discharge conveyor 70 supplies the square-shaped cloth Y developed in a square shape to the processing device of the next process installed behind.
上記(1)~(3)と(4)との間では、ダンパ67が切換えられるが、その切換え動作はモータ80で行われる。そうすると既述のごとくダンパ67の切換え動作時間が短くなるので、ダクト61,65の吸引効率が高くなる。
The damper 67 is switched between the above (1) to (3) and (4), and the switching operation is performed by the motor 80. As a result, the switching operation time of the damper 67 is shortened as described above, and the suction efficiency of the ducts 61 and 65 is increased.
