The operation of the above sheet sticking apparatus EA1 will be described.
First, with respect to the sheet sticking apparatus EA1 in which each member is arranged at the initial position shown by the solid line in FIG. 1A, the user of the sheet sticking apparatus EA1 (hereinafter, simply referred to as “user”) is A signal for starting automatic operation is input through an operation means (not shown) such as a personal computer. At this time, the user drives the displacement means 62 and the curvature changing means 63, and the displacement means 62 and the curvature are adjusted so that the camera 52 can image the blind spot area BA in the marking area MA that the camera 52 cannot image. The changing unit 63 is driven to adjust the position and angle of the stainless plate 61, the curvature of the concave mirror surface 61A, and the like. In addition, the user inputs the original fabric information such as numerical values, characters, and symbols indicating the product name and model of the original fabric RS used in the sheet sticking apparatus EA1 to the control means 30 through the operating means (not shown). ..

Next, after the user opens the cover member 18, as shown in FIG. 1B, the second opening HL2 of the hole HL is abutted against the stopper 11A, and the original roll material RR is set on the support roller 11. , The original fabric RS is wound around as shown in FIG. 1(A) to close the cover member 18. Then, an imaging device such as a camera or a projector or a detection unit (not shown) such as various sensors such as an optical sensor and an ultrasonic sensor detects that the cover member 18 is closed, and at this timing, the imaging unit 50 causes the camera. 52 is driven, the imaging area PA is imaged, and the captured image is output to the control means 30. At this time, as shown in FIG. 1C, the camera 52 has an inner peripheral surface HL3 of the hole HL that is directly visible and an inner peripheral surface HL3 of the hole HL that is visible as a reflection by the concave mirror surface 61A. Since the entire mark giving area MA can be included in the captured image, the mark MK cannot be imaged. Specifically, as shown in FIG. 1C, when there is a mark MK at the tip of the arrow numbered MP (the blind spot area BA of the camera 52), the camera 52 cannot see it directly, Since the mark MK is reflected as a mirror image on the concave curved surface 61A of the stainless steel plate 61, the camera 52 can indirectly image the mark MK, and can always take the image at a predetermined timing. Needless to say, the mark MK not in the blind spot area BA can be directly imaged by the camera 52.

When the mark MK output from the camera 52 is input to the control means 30, the control means 30 converts the mark MK into input information such as numbers, characters, and symbols according to a certain rule, and is input first. It is determined whether or not it matches the original fabric information. Here, when the control means 30 determines that the input information does not match the original information, the control means 30 outputs a drive command to the notification means 40 and the sheet sticking apparatus EA1 does not operate. Interlock. Then, the notification means 40 drives the sound generator or the like to notify the user that the input information does not match the original information. After that, when the user recognizes the notification by the notification means 40, the set original roll material RR is removed from the sheet attaching device EA1 and then another original material roll RR is attached in the same manner as above. Set in the device EA1.

Next, when the control means 30 determines that the input information matches the original information in the same manner as described above, the control means 30 outputs a drive stop command to the notification means 40 and the sheet concerned. The interlock of the sticking device EA1 is released. Then, the notification means 40 stops the driving of the sound generator, etc., and informs the user that the input information is suitable for the original fabric information, and then the sticking means 10 drives the rotation motor 15A, so that the original When the anti-RS is fed out and the leading end portion of the leading adhesive sheet AS in the feeding direction is peeled by the peeling edge 13A of the peeling plate 13 for a predetermined length, the driving of the rotation motor 15A is stopped. Then, when a user or an unillustrated transfer means such as an articulated robot or a belt conveyor places the adherend WK on the support table 22, the adhered object transfer means 20 drives the depressurizing means (not shown), and the holding surface. At 22A, adsorption and holding of the adherend WK is started.

Next, when the adherend conveying means 20 drives the linear motor 21 to move the support table 22 to the left and the adherend WK reaches a predetermined position, the sticking means 10 drives the rotation motor 15A, The original fabric RS is paid out in accordance with the moving speed of the adherend WK. As a result, the adhesive sheet AS is released from the release sheet RL, and the adhesive sheet AS released from the release sheet RL is applied to the adherend WK by the pressing roller 14 as shown by the chain double-dashed line in FIG. It is pressed and attached. Next, when the front end portion in the feeding direction of the next adhesive sheet AS after the leading adhesive sheet AS is peeled by the peeling edge 13A of the peeling plate 13 for a predetermined length, the sticking means 10 stops driving the rotation motor 15A. To do. Then, when the entire adhesive sheet AS is attached to the adherend WK and the support table 22 reaches a predetermined position on the left side of the pressing roller 14, the adherend conveying means 20 stops driving the linear motor 21, and then is not shown. The driving of the pressure reducing means is stopped, and the suction holding of the adherend WK on the holding surface 22A is released. Next, when the user or a conveying means (not shown) conveys the adherend WK to which the adhesive sheet AS is attached to the next step, the adherend conveying means 20 drives the linear motor 21 to move the support table 22 to the initial position. After returning, the same operation as above is repeated.

According to the above-described embodiment, the blind spot area BA of the camera 52 in the marking area MA is displayed in the image pickup area PA by the concave mirror surface 61A, so that the relative rotation between the image pickup means 50 and the hole HL becomes unnecessary.
