Yes.

次に、本実施形態におけるシート貼付装置１０の動作について説明する。
先ず、各部材が初期位置で待機する図１中実線で示すシート貼付装置１０に対し、作業者が原反ＲＳを同図のようにセットした後、図示しない操作パネルやパーソナルコンピュータ等の入力手段を介して自動運転開始の信号を入力すると、繰出手段２０が回動モータ２３Ａを駆動し、原反ＲＳを繰り出す。そして、図１に示すように、先頭の接着シートＡＳの繰出方向先端部が剥離板３０で剥離シートＲＬから所定長さ剥離したことがカメラ等の撮像手段や光学センサ等の図示しない検出手段に検出されると、繰出手段２０が回動モータ２３Ａの駆動を停止し、スタンバイ状態となる。 Next, operation | movement of the sheet sticking apparatus 10 in this embodiment is demonstrated.
First, after the members set the original fabric RS as shown in the figure with respect to the sheet sticking device 10 indicated by the solid line in FIG. 1 in which each member stands by at the initial position, input means such as an operation panel or a personal computer (not shown) When the automatic operation start signal is input via, the feeding means 20 drives the rotation motor 23A and feeds the original fabric RS. Then, as shown in FIG. 1, the leading end of the adhesive sheet AS in the feeding direction is peeled from the release sheet RL by a predetermined length by the release plate 30 to an imaging means such as a camera or a detection means not shown such as an optical sensor. When detected, the feeding means 20 stops the rotation motor 23A and enters a standby state.

次いで、人手または多関節ロボットやベルトコンベア等の図示しない移送手段が被着体ＷＫを支持面８２Ａ上に載置すると、移動手段８０が図示しない減圧手段を駆動し、支持面８２Ａで被着体ＷＫを吸着保持した後、リニアモータ８１を駆動し、搬送テーブル８２を左方に移動させる。そして、被着体ＷＫが所定位置に到達したことがカメラ等の撮像手段や光学センサ等の図示しない検知手段に検知されると、繰出手段２０が回動モータ２３Ａを駆動し、被着体ＷＫの搬送速度に合わせて原反ＲＳを繰り出す。   Next, when a transfer means (not shown) such as a human hand or an articulated robot or a belt conveyor places the adherend WK on the support surface 82A, the moving means 80 drives a decompression means (not shown), and the adherend is supported by the support surface 82A. After attracting and holding the WK, the linear motor 81 is driven to move the transport table 82 to the left. Then, when it is detected by an imaging means such as a camera or a detection means (not shown) such as an optical sensor that the adherend WK has reached a predetermined position, the feeding means 20 drives the rotation motor 23A, and the adherend WK. The raw fabric RS is fed out in accordance with the transport speed.

続いて、図２（Ａ）に示すように、接着シートＡＳの繰出方向先端部が押圧ローラ４０によりリングフレームＲＦに貼付されたことが図示しない検知手段により検知されると、繰出手段２０および移動手段８０が回動モータ２３Ａおよびリニアモータ８１の駆動を停止する。次に、進退手段５０が直動モータ５１を駆動し、図２（Ｂ）に示すように、剥離板３０を押圧ローラ４０から離間させた後、接離手段７０が直動モータ７１を駆動し、図２（Ｃ）に示すように、クラウンローラ６０を下降させ、当該クラウンローラ６０を剥離板３０で剥離された接着シートＡＳの未貼付部に押し当てる。これにより、接着シートＡＳの中央部が押し下げられ、図３に示すように、接着シートＡＳの幅方向ＣＣに張力が付与されて、当該接着シートＡＳが幅方向に縮もうとすることを抑制する。そして、繰出手段２０および移動手段８０が回動モータ２３Ａおよびリニアモータ８１を駆動し、図２（Ｄ）に示すように、再度原反ＲＳを繰り出しつつ、搬送テーブル８２を左方に移動させる。これにより、先頭の接着シートＡＳが剥離シートＲＬから剥離されて被着体ＷＫに貼付され、一体物ＷＫ１が形成される。なお、次の接着シートＡＳの繰出方向先端部が剥離板３０で剥離シートＲＬから所定長さ剥離したことが図示しない検出手段に検出されると、繰出手段２０が回動モータ２３Ａの駆動を停止し、再びスタンバイ状態となる。   Subsequently, as shown in FIG. 2 (A), when it is detected by a detection means (not shown) that the leading end portion of the adhesive sheet AS is stuck to the ring frame RF by the pressing roller 40, the supply means 20 and the movement The means 80 stops the driving of the rotation motor 23A and the linear motor 81. Next, the advancing / retracting means 50 drives the linear motion motor 51, and as shown in FIG. 2 (B), after the separation plate 30 is separated from the pressing roller 40, the contact / separation means 70 drives the linear motion motor 71. As shown in FIG. 2C, the crown roller 60 is lowered, and the crown roller 60 is pressed against the unattached portion of the adhesive sheet AS peeled by the peeling plate 30. As a result, the center portion of the adhesive sheet AS is pushed down, and as shown in FIG. 3, tension is applied in the width direction CC of the adhesive sheet AS, and the adhesive sheet AS is prevented from shrinking in the width direction. . Then, the feeding means 20 and the moving means 80 drive the rotation motor 23A and the linear motor 81, and move the conveyance table 82 to the left while feeding the original fabric RS again as shown in FIG. 2 (D). As a result, the leading adhesive sheet AS is peeled off from the release sheet RL and attached to the adherend WK to form an integrated object WK1. When the detection means (not shown) detects that the leading edge of the next adhesive sheet AS is peeled from the release sheet RL by the release plate 30 for a predetermined length, the supply means 20 stops driving the rotation motor 23A. Then, it enters the standby state again.

一体物ＷＫ１が形成されると、移動手段８０がリニアモータ８１の駆動を停止し、搬送テーブル８２を所定の位置で停止させた後、図示しない減圧手段の駆動を停止するので、人手または図示しない移送手段が、一体物ＷＫ１を次工程に搬送する。そして、移動手段８０がリニアモータ８１を駆動し、搬送テーブル８２を初期位置に復帰させた後、上記同様の動作が繰り返される。   When the one-piece WK1 is formed, the moving unit 80 stops driving the linear motor 81, stops the conveyance table 82 at a predetermined position, and then stops driving the decompression unit (not shown). The transfer means conveys the integrated object WK1 to the next process. Then, after the moving unit 80 drives the linear motor 81 and returns the conveyance table 82 to the initial position, the same operation as described above is repeated.

以上のような本実施形態によれば、先端部が被着体ＷＫに貼付された接着シートＡＳにおける未貼付部に、当該接着シートＡＳの繰出方向ＢＢに交差する幅方向ＣＣへの張力を付与するので、接着シートＡＳに皺が発生した状態で被着体ＷＫに貼付されることを極力防止することができる。   According to the present embodiment as described above, the tension in the width direction CC that intersects the feeding direction BB of the adhesive sheet AS is applied to the unattached portion of the adhesive sheet AS with the tip portion attached to the adherend WK. Therefore, it is possible to prevent the adhesive sheet AS from being attached to the adherend WK in a state where wrinkles are generated.

本発明における手段および工程は、それら手段および工程について説明した動作、機能または工程を果たすことができる限りなんら限定されることはなく、まして、前記実施形態で示した単なる一実施形態の構成物や工程に全く限定されることはない。例えば、繰出手段は、複数の接着シートが帯状の剥離シートに所定の間隔をあけて仮着された原反を繰り出すものであれば、出願当初の技術常識に照らし合わせてその範囲内であればなんら限定されることはない（他の手段および工程についての説明は省略する）。   The means and steps in the present invention are not limited in any way as long as they can perform the operations, functions, or steps described with respect to those means and steps. The process is not limited at all. For example, if the feeding means feeds the original fabric temporarily attached to the strip-shaped release sheet with a predetermined interval, the feeding means is within the range in light of the common general technical knowledge at the beginning of the application. There is no limitation at all (the description of other means and steps is omitted).

The raw fabric RS may be paid out.
The feeding means 20 feeds the original fabric RS having a belt-like adhesive sheet base material temporarily attached to one surface of the release sheet RL, and the adhesive sheet base material upstream of the release plate 30 in the feed direction of the original fabric RS.

As such a cutting means, a cutter blade, a cutter roller, a laser cutter, a heating wire, a spray of gas or liquid, or the like can be adopted.

剥離板３０は、図３中二点鎖線で示すように、原反ＲＳの繰出方向前端部の中央部が当該繰出方向上流側に凹となる凹部３１を備えていてもよいし、当該中央部が接着シートＡＳの非接着面側から接着面側に凹んだ形状でもよい。このように凹部３１や凹んだ形状を形成することで、クラウンローラ６０の中央部が入り込むスペースを大きくすることができる上、クラウンローラ６０の中央部で押し下げられる接着シートＡＳの中央部を折り曲げ易くすることができる。
剥離手段は、剥離板３０の代わりに、丸棒や回転可能な剥離用ローラを採用してもよい。 As shown by a two-dot chain line in FIG. 3, the peeling plate 30 may include a concave portion 31 in which a central portion of the front end portion of the raw fabric RS is recessed on the upstream side in the feeding direction. However, the shape of the adhesive sheet AS may be recessed from the non-adhesive surface side to the adhesive surface side. By forming the concave portion 31 or the concave shape in this way, a space for the central portion of the crown roller 60 to enter can be increased, and the central portion of the adhesive sheet AS that is pushed down by the central portion of the crown roller 60 can be easily bent. can do.
As the peeling means, a round bar or a rotatable peeling roller may be employed instead of the peeling plate 30.

押圧手段は、ブレード材、ゴム、樹脂、スポンジ等による押圧部材を採用してもよいし、大気やガス等のエアの噴き付けにより押圧する構成を採用してもよい。
押圧手段は、押圧部材を移動させずに被着体ＷＫを押圧部材に向けて移動させて押圧してもよいし、被着体ＷＫを移動させずに押圧部材を被着体ＷＫに向けて移動させて押圧してもよいし、押圧部材と被着体ＷＫとの両方を互いに移動させて押圧してもよい。 As the pressing means, a pressing member made of a blade material, rubber, resin, sponge, or the like may be employed, or a structure of pressing by blowing air such as air or gas may be employed.
The pressing means may move and press the adherend WK toward the pressing member without moving the pressing member, or direct the pressing member toward the adherend WK without moving the adherend WK. It may be moved and pressed, or both the pressing member and the adherend WK may be moved and pressed together.

進退手段５０は、繰出手段２０を移動させて剥離板３０を押圧ローラ４０に対して進退させる構成を採用してもよく、この場合、直動モータ５１はあってもよいし、なくてもよい。
