The operation of the above sheet pasting device EA will be explained.
First, a user of the sheet applicator EA (hereinafter simply referred to as "user") sets the sheet applicator EA in which each member is placed at the initial position shown by the solid line in FIG. After setting the original fabric RS, a signal to start automatic operation is inputted via an operation means (not shown) such as an operation panel or a personal computer. Then, the supply means 10 drives the rotary motors 15A and 17A to feed out the original fabric RS, and as shown in FIG. When a predetermined length of the release sheet RL is peeled off from the folded portion of the release sheet RL by the edge 14A, the driving of the rotation motors 15A and 17A is stopped.

Next, as shown in FIG. 1(A), a user or a transport means (not shown) such as an articulated robot or a belt conveyor moves the adherend WK onto the support surface so that the center WKC of the adherend overlaps the center 43C of the table. When placed on the supporting surface 43A, the moving means 40 drives a pressure reducing means (not shown) to start suction and holding on the supporting surface 43A. At this time, the outer peripheral surface WK3 of the adherend WK is located in the detection area of the detection device 51. Thereafter, the moving means 40 and the notch detecting means 50 drive the rotary motor 42 and the detecting device 51 to rotate the adherend WK in the counterclockwise direction RD in a top view looking down from above, so that the detecting device 51 has a V notch. Memorize the VN position. Next, based on the memory of the detection device 51, the moving means 40 starts pasting the adhesive sheet AS from the center of the V-notch VN formation position, as shown by the two-dot chain line in FIG. 1(A). After positioning the adherend WK, the rotation motor 42 is stopped.

Then, the moving means 40 drives the linear motor 41 to move the support table 43 to the left, so that the table center 43C (adherent center WKC) is at the reference position, as shown by the two-dot chain line in FIG. 1(A). When it matches RP, driving of the linear motor 41 is stopped. Next, the supplying means 10 and the moving means 40 drive the rotary motors 15A, 17A, and 42 to supply the adhesive sheet AS while rotating the adherend WK in the counterclockwise rotation direction RD when viewed from above. At the same time, the pasting means 20 drives the hot air blower 22 to blow hot air HA toward the adherend WK. As a result, the adhesive sheet AS is peeled off from the release sheet RL at the folded part of the release sheet RL, and the adhesive sheet AS peeled off from the release sheet RL is separated by the two-dot chain line in FIG. As shown in FIG. 2, the adhesive is pressed and attached to the outer circumferential surface WK3 of the adherend WK by the first pressing roller 21 in a state in which the protruding area ASH is formed. After that, when the adhesive sheet AS attached to the outer peripheral surface WK3 passes through the hot air blowing area of the hot air blower 22, the hot air HA is blown onto the adhesive sheet AS, and the protruding area ASH is deformed by the hot air HA, as shown in FIG. 1(C). As shown in the figure, one surface of the adherend WK is bent in the direction of WK1 and the other surface of the adherend WK is bent in the direction of WK2. After that, when the rotation motors 15A, 17A, and 42 and the hot air blower 22 continue to be driven, the adhesive sheet AS becomes as shown in FIGS. 1(D), (E), and 2(A).

Next, when the leading end ASF in the supply direction of the next adhesive sheet AS following the first adhesive sheet AS is peeled off from the release sheet RL by a predetermined length at the folded part of the release sheet RL, the supply means 10 is activated by the rotating motor. The driving of 15A and 17A is stopped, and the supply of the adhesive sheet AS is stopped. Then, when the protruding area ASH of the rear end ASR in the supply direction of the first adhesive sheet AS passes through the hot air blowing area of the hot air blower 22, the pasting means 20 stops driving the hot air blower 22, and the rear end in the supply direction When the protruding area ASH of the ASR is pasted on one surface WK1 and the other surface WK2 of the adherend WK by the third pressing roller 24, as shown in FIG. An integral body UP is formed in which the adhesive sheet AS is attached to the outer edge of the surface WK1, the outer edge of the other surface WK2, and the outer peripheral surface WK3. Next, based on the memory of the detection device 51, the moving means 40 detects when the V notch VN reaches the gas spraying position of the nozzle 32, as shown by the two-dot chain line in FIG. 2(B) and in FIG. 2(C). , the moving means 40 stops driving the rotation motor 42.

After that, the mutual adhesion means 30 drives the air supply means 31, and as shown in FIG. 2(D), gas AR is sprayed from each nozzle 32 onto the adhesive sheet AS attached to the adherend WK, and the V-notch VN is The adhesive surfaces ASS of the adhesive sheet AS are adhered to each other in the forming section. Next, when mutual adhesion of the adhesive surfaces ASS of the adhesive sheet AS is completed, the mutual adhesion means 30 stops driving the air supply means 31, and then the moving means 40 drives the linear motor 41 to move the support table 43 to the initial position. , the drive of the pressure reducing means (not shown) is stopped, and the adsorption and holding on the support surface 43A is released. Then, the user or a conveying means (not shown) removes the integral object UP from the support surface 43A and conveys the integral object UP to the next process, and thereafter the same operation as described above is repeated.

It may be composed of a deformable member such as rubber or resin, or it may be composed of a non-deformable member, and a supported member (held member) such as a supporting (holding) means or a supporting (holding) member may be used. If something to support (hold) is used, gripping means such as mechanical chuck or chuck cylinder, Coulomb force, adhesive (adhesive sheet, adhesive tape), adhesive (adhesive sheet, adhesive tape), magnetic force, Bernoulli adsorption It is also possible to adopt a structure in which the supported member is supported (held) by a suction suction device, a driving device, etc., or by cutting the member to be cut using a cutting means or a cutting member, or by making a cut or cutting line in the member to be cut. If a forming device is used, instead of or in combination with the above examples, a cutter blade, laser cutter, ion beam, thermal power, heat, water pressure, heating wire, spraying of gas or liquid, etc. It is also possible to use a cutting device or to move the cutting object using a combination of suitable drive equipment.
