And a support table 72 having a possible support surface 72A.
以上のシート供給装置１０が採用されたシート貼付装置ＳＡの動作を説明する。
先ず、図１中実線で示す初期位置に各部材が配置されたシート貼付装置ＳＡに対し、シート貼付装置ＳＡの使用者（以下、単に「使用者」という）が同図のように原反ＲＳをセットした後、操作パネルやパーソナルコンピュータ等の図示しない操作手段を介して、シート貼付装置ＳＡに運転開始の信号を入力する。すると、当接補助手段５０が図示しない加圧手段を駆動し、ノズル５１から気体を吹き付けるとともに、繰出手段２０が回動モータ２１、２４Ａを駆動し、原反ＲＳを繰り出した後、原反停止センサ２７がシート後方段差を検知すると、回動モータ２１、２４Ａの駆動を停止し、原反ＲＳの繰り出しを停止する。
The operation of the sheet sticking apparatus SA in which the above sheet feeding apparatus 10 is adopted will be described.
First, with respect to the sheet sticking apparatus SA in which each member is disposed at the initial position shown by the solid line in FIG. 1, the user of the sheet sticking apparatus SA (hereinafter simply referred to as “user”) After setting, the operation start signal is input to the sheet sticking apparatus SA via an operation unit (not shown) such as an operation panel or a personal computer. Then, the contact assisting means 50 drives the pressurizing means (not shown) to blow the gas from the nozzle 51, and the feeding means 20 drives the rotation motors 21 and 24A to feed the original roll RS, and then the original roll is stopped. When the sensor 27 detects the seat back level difference, the drive of the rotation motors 21 and 24A is stopped, and the feeding of the original fabric RS is stopped.
ここで、上記の要領で原反ＲＳの繰り出しを停止すると、通常であれば、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ＡＳ１が剥離板３０の剥離縁３０Ａで剥離され、ノズル５１から吹き付けられる気体にも補助されて繰出方向先端部ＡＳ１が接点部４４に当接して閉回路ＣＴが形成される。そして、供給部４１から供給されて閉回路ＣＴを導通する電気エネルギーを検知部４５が検知し、シート供給装置１０がスタンバイ状態となる。 Here, when the feeding of the raw fabric RS is stopped in the above manner, the leading end AS1 of the leading adhesive sheet AS is peeled off at the peeling edge 30A of the peeling plate 30, as shown in FIG. Assisted by the gas blown from the nozzle 51, the delivery direction tip end portion AS1 abuts on the contact portion 44 to form a closed circuit CT. Then, the detection unit 45 detects the electrical energy supplied from the supply unit 41 and conducting the closed circuit CT, and the sheet supply device 10 is in the standby state.
一方、上記の要領で原反ＲＳの繰り出しを停止した際、図２（Ａ）に示すように、先頭の接着シートＡＳの繰出方向先端部ＡＳ１が、剥離シートＲＬと共に駆動ローラ２４方向に繰り出されると、繰出方向先端部ＡＳ１が接点部４４に当接せず、検知部４５が電気エネルギーを検知しないことで、剥離不良が発生したことを剥離不良検知手段４０が検知する。すると、繰出手段２０が回動モータ２１、２４Ａを駆動し、先頭の接着シートＡＳの繰出方向先端部ＡＳ１が、全て剥離板３０の剥離縁３０Ａで折り返される前の位置に達するまで原反ＲＳを引き戻した後、再度、原反ＲＳを繰り出すリトライ動作を行う。そして、図２（Ｂ）に示すように、先頭の接着シートＡＳの繰出方向先端部ＡＳ１が剥離板３０の剥離縁３０Ａで剥離されると、当該繰出方向先端部ＡＳ１が接点部４４に当接して閉回路ＣＴが形成され、閉回路ＣＴを導通する電気エネルギーを検知部４５が検知し、シート供給装置１０がスタンバイ状態となる。 On the other hand, when the feeding of the raw sheet RS is stopped in the above manner, the leading end AS1 of the leading adhesive sheet AS in the feeding direction is fed out in the direction of the drive roller 24 together with the release sheet RL as shown in FIG. The peeling defect detection means 40 detects that the peeling defect has occurred because the leading end portion AS1 in the feeding direction is not in contact with the contact portion 44 and the detecting portion 45 does not detect the electrical energy. Then, the feeding means 20 drives the rotation motors 21 and 24A, and until the leading end portion AS1 of the leading adhesive sheet AS in the feeding direction reaches the position before it is completely folded back by the peeling edge 30A of the peeling plate 30, After pulling back, a retry operation is performed to feed the original fabric RS again. Then, as shown in FIG. 2B, when the leading end AS1 of the leading adhesive sheet AS is peeled off at the peeling edge 30A of the peeling plate 30, the leading direction AS1 contacts the contact portion 44. Thus, the closed circuit CT is formed, and the detection unit 45 detects the electrical energy that conducts the closed circuit CT, and the sheet feeding device 10 is in the standby state.
次いで、使用者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搬送手段が、被着体ＷＫを支持テーブル７２上に載置すると、移動手段７０が図示しない減圧手段を駆動し、支持面７２Ａでの被着体ＷＫの吸着保持を開始する。その後、移動手段７０がリニアモータ７１を駆動し、支持テーブル７２を左方へ移動させ、被着体ＷＫが所定の位置に到達すると、繰出手段２０が回動モータ２１、２４Ａを駆動し、被着体ＷＫの移動速度に合わせて原反ＲＳを繰り出す。これにより、接着シートＡＳは、図１中二点鎖線で示すように、剥離板３０の剥離縁３０Ａで剥離シートＲＬから剥離されつつ、押圧ローラ６１によって被着体ＷＫの上面に押圧されて貼付される。 Next, when the user or a transfer means (not shown) such as an articulated robot or a belt conveyor places the adherend WK on the support table 72, the moving means 70 drives the pressure reduction means (not shown) to move the support surface 72A. The adsorption holding of the adherend WK is started. Thereafter, the moving means 70 drives the linear motor 71 to move the support table 72 to the left, and when the adherend WK reaches a predetermined position, the feeding means 20 drives the rotation motors 21 and 24A to adhere The raw fabric RS is fed out according to the moving speed of the adherend WK. Thereby, the adhesive sheet AS is pressed from the upper surface of the adherend WK by the pressing roller 61 while being peeled from the peeling sheet RL at the peeling edge 30A of the peeling plate 30, as shown by the two-dot chain line in FIG. Be done.
接着シートＡＳ全体が被着体ＷＫに貼付された後、原反停止センサ２７が再びシート後方段差を検知した時点で、繰出手段２０が回動モータ２１、２４Ａの駆動を停止し、原反ＲＳの繰り出しを停止する。このときも、繰出手段２０は、繰出方向先端部ＡＳ１が接点部４４に当接せず、検知部４５が電気エネルギーを検知しない場合は、上記のリトライ動作を行い、繰出方向先端部ＡＳ１が接点部４４に当接し、閉回路ＣＴを導通する電気エネルギーを検知部４５が検知すると、シート供給装置１０が再びスタンバイ状態となる。 After the entire adhesive sheet AS is attached to the adherend WK, the feeding means 20 stops the driving of the rotation motors 21 and 24A when the original fabric stop sensor 27 detects the sheet rear step again, and the original fabric RS Stop feeding. Also at this time, when the delivery direction tip end portion AS1 does not contact the contact portion 44 and the detection unit 45 does not detect the electrical energy, the delivery means 20 performs the above retry operation, and the delivery direction tip end portion AS1 is a contact point When the detecting unit 45 detects the electrical energy which abuts the portion 44 and conducts the closed circuit CT, the sheet feeding device 10 is in the standby state again.
次に、接着シートＡＳ全体が貼付された被着体ＷＫが押圧ローラ６１の左方の所定位置に到達すると、移動手段７０がリニアモータ７１および図示しない減圧手段の駆動を停止する。そして、使用者または図示しない搬送手段が、接着シートＡＳが貼付された被着体ＷＫを次の工程に搬送した後、移動手段７０がリニアモータ７１を駆動し、支持テーブル７２を初期位置に復帰させ、以降、上記同様の動作が繰り返される。 Next, when the adherend WK to which the entire adhesive sheet AS is attached reaches a predetermined position on the left side of the pressing roller 61, the moving means 70 stops driving the linear motor 71 and the pressure reducing means (not shown). Then, after the user or the conveying means (not shown) conveys the adherend WK to which the adhesive sheet AS is adhered to the next step, the moving means 70 drives the linear motor 71 to return the support table 72 to the initial position. Thereafter, the same operation as described above is repeated.
以上のような実施形態によれば、接着シートＡＳの繰出方向先端部ＡＳ１が接点部４４に当接しないことで剥離不良を検知するので、接着シートＡＳの透明度が高い場合や、当該接着シートＡＳの検知部の光量が少ない場合等であっても、検知結果に影響することがなく、接着シートＡＳの剥離不良を誤認識することを防止することができる。 According to the embodiment as described above, since the peeling failure is detected by the leading end portion AS1 in the delivery direction of the adhesive sheet AS not in contact with the contact portion 44, the case where the transparency of the adhesive sheet AS is high or the adhesive sheet AS Even when the light amount of the detection unit is small or the like, the detection result is not affected, and erroneous recognition of the peeling failure of the adhesive sheet AS can be prevented.
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、帯状の剥離シートに接着シートが仮着された原反を繰り出し可能なものであれば、出願当初の技術常識に照らし合わせ、その技術範囲内のものであればなんら限定されることはない（その他の手段および工程も同じ）。 The means and steps in the present invention are not limited in any way as long as the operations, functions or steps described in the means and steps can be performed, and it is needless to say that the constitutions of only one embodiment shown in the above embodiment or There is no limitation to the process. For example, the feeding means is limited insofar as it is within the technical scope in light of the technical common sense at the time of filing as long as it can deliver the raw fabric having the adhesive sheet temporarily attached to the strip-like release sheet. There is nothing to do (the other means and steps are the same).
例えば、シート貼付装置ＳＡは、前記実施形態で示した剥離不良検知手段４０に代えて、図３各図に示すように、剥離板３０で剥離された接着シートＡＳの繰出方向先端部ＡＳ１が当接する接点部４８Ａを有する当接検知手段としての接触センサ４８を備えた剥離不良検知手段４０Ａを採用してもよい。
剥離不良検知手段４０Ａは、接着シートＡＳの繰出方向先端部ＡＳ１が接点部４８Ａに当接したことを接触センサ４８が検知することで、当該繰出方向先端部ＡＳ１が剥離板３０で剥離されたことを検知し、接着シートＡＳの繰出方向先端部ＡＳ１が接点部４８Ａに当接しないことを接触センサ４８が検知することで剥離不良を検知する構成となっている。
