A procedure for applying the adhesive sheet AS to the adherend WK in the sheet applying apparatus 10 described above will be described.
First, a user of the sheet sticking device 10 (hereinafter simply referred to as a "user") is placed in the initial positions of the sheet sticking device 10 in the state indicated by the solid line in FIG. And the connection tape CT is set as shown in the figure, and a signal for starting automatic operation is inputted via an operation means (not shown) such as an operation panel or a personal computer. Then, the feeding means 40 and the connecting means 80 drive their decompressing means (not shown) to start sucking and holding the raw material RS2 on the holding surface 49A, and start sucking and holding the connection tape CT on the holding surface 81A. . In addition, the feeding means 40 drives the rotation motors 42 and 45A to feed the original fabric RS1. Then, detection means (not shown) such as imaging means such as a camera or a projector and various sensors such as an optical sensor and an ultrasonic sensor detect that the leading adhesive sheet AS has been peeled off by the peeling plate 50 by a predetermined length. Then, the feeding means 40 stops driving the rotary motors 42 and 45A and enters a standby state.

Next, when the user or conveying means (not shown) such as a belt conveyor or an articulated robot places the adherend WK on the support surface 92A as indicated by the solid line in FIG. The depressurizing means is driven to start holding the adherend WK on the support surface 92A. Next, the support means 90 drives the linear motor 91 to move the table 92 leftward. Then, when the arrival of the adherend WK at a predetermined position is detected by an imaging means such as a camera or a projector, or various sensors such as an optical sensor or an ultrasonic sensor (not shown), the feeding means 40 drives the rotary motors 42 and 45A to feed the original fabric RS1 in accordance with the moving speed of the table 92. As a result, the adhesive sheet AS is separated from the release sheet RL by the release plate 50, and is pressed and attached to the adherend WK by the pressure roller 60. FIG.

As indicated by the chain double-dashed line in FIG. 1, the attachment of the adhesive sheet AS to the adherend WK is completed, and detection means (not shown) detects that the next adhesive sheet AS has been peeled off by the peeling plate 50 for a predetermined length. Then, the feeding means 40 stops driving the rotating motors 42 and 45A, and the supporting means 90 stops driving the linear motor 91 and the decompressing means (not shown). Then, after the user or the transport means (not shown) transports the adherend WK to the next step, the support means 90 drives the linear motor 91 to return the table 92 to the initial position.

Thereafter, after repeating the same operation as described above, when the original fabric RS2 is connected to the original fabric RS1 before the adhesive sheet AS in the original fabric RS1 is used up, the user operates the original fabric mold through an operation means (not shown). input a signal for conversion. Then, the feeding means 40 drives the rotating motors 42 and 45A to rewind the original fabric RS1. Then, it is detected that the original fabric RS1 has been rewound by a predetermined length and that the original fabric RS1 has been wound up until the leading adhesive sheet AS of the original fabric RS1 is positioned upstream of the predetermined cutting position in the original fabric feeding direction. When detected by the means 79, the feeding means 40 stops driving the rotation motors 42 and 45A. Next, the cutting means 70 drives the direct-acting motor 77 and the decompression means (not shown) to lower the table 78 as shown in FIG. . After that, the cutting means 70 drives the direct-acting motor 71 and the linear motor 75 to raise the cutting blade 76 as indicated by the two-dot chain line in FIG. to move it back and forth. As a result, the original fabric RS1 is cut to form a rear end portion RS1R in the original fabric RS1 as shown in FIG. 2(B). After that, the cutting means 70 drives the direct-acting motor 71 to lower the cutting blade 76 .

Next, the feeding means 40 drives the rotation motors 42 and 45A, and as shown in FIG. Stop driving 42 and 45A. After that, the feeding means 40 drives the direct-acting motor 48 to raise the table 49 so that the leading edge RS2F of the original fabric RS2 is adjacent to the trailing edge RS1R of the original fabric RS1, as shown in FIG. 2(B). Then, the connecting means 80 drives the rotating motor 73 and the direct-acting motor 71, and as shown in FIG. After facing each other, the holding plate 81 is lifted. As a result, the connecting tape CT is pressed and attached to the trailing edge RS1R of the web RS1 and the leading edge RS2F of the web RS2 by the holding plate 81, and the web RS2 is connected to the trailing edge RS1R.

After that, the feeding means 40, the cutting means 70, and the connecting means 80 stop driving their decompressing means (not shown), and release the original fabrics RS1, RS2 and the connection tape CT from the suction and holding. Next, the feeding means 40 and the cutting means 70 drive the linear motion motors 48, 71, 77 and the rotary motor 73 to return the tables 49, 78 and the rotary body 74 to their initial positions. After that, the feeding means 40 drives the rotation motors 41A and 43 to rotate the support arm 41 while applying a predetermined tension to the original sheet RS2, thereby positioning the support roller 30 upward. As a result, the support roller 30 becomes the first support means, the other material RS2 supported by the support roller 30 becomes the previous material RS1, and the support roller 20 becomes the second support means. , the previous material RS1 supported by the support roller 20 or another material replaced with the support roller 20 becomes the other material RS2, and the same operation as described above is repeated thereafter.

According to the embodiment as described above, the original fabric RS1 is rewound by a predetermined length to form the rear end portion RS1R, and the original fabric RS2 is connected to the rear end portion RS1R. The adhesive sheet AS can be used for the next sheet attachment, and wasteful consumption of the adhesive sheet AS can be prevented.

When a heat-sensitive adhesive sheet AS is used, it may be adhered by an appropriate method such as providing a heating means such as a suitable coil heater or heat pipe for heating the adhesive sheet AS. Further, such adhesive sheet AS includes, for example, a single-layer adhesive layer only, an intermediate layer between the base sheet and the adhesive layer, and a cover layer on the upper surface of the base sheet. Three or more layers, or a so-called double-sided adhesive sheet that allows the base sheet to be peeled off from the adhesive layer may be used. It may have a single layer or multiple layers without an intermediate layer.
Examples of the adherend WK include food, resin containers, semiconductor wafers such as silicon semiconductor wafers and compound semiconductor wafers, information recording substrates such as circuit boards and optical discs, glass plates, steel plates, ceramics, wood plates, resin plates, and the like. , any form of member or article, etc. can also be targeted. In addition, the adhesive sheet AS is replaced with a functional and application reading, for example, an information label, a decorative label, a protective sheet, a dicing tape, a die attach film, a die bonding tape, a recording layer forming resin sheet, etc. Sheets, films, tapes, etc. of any shape can be applied to any adherend WK as described above.
