  The urging unit 70 includes an air nozzle 71 connected to a pressurizing unit (not shown) such as a pressurizing pump or a turbine.

  Next, a method of sticking the adhesive sheet AS using the sheet sticking device 10 in the present embodiment will be described.

First, after an operator sets the original fabric RS as shown in FIG. 1, when an operation start signal is input via an input means such as an operation panel or a personal computer (not shown), the supply means 20 causes the rotation motor 24A and the illustration. Drive the drive device that does not, and feed out the raw fabric RS. Then, when a detection unit (not shown) such as an optical sensor or a camera detects that a predetermined amount of the leading end of the adhesive sheet AS in the feeding direction is peeled off by the peeling plate 23, the supply unit 20 drives the rotation motor 24A and a drive (not shown). The drive of the device is stopped and the device enters a standby state.
Then, when the transport unit 60 drives the carry-in unit 68 and places the adherend WK on the set of support rollers 62B, the transport unit 60 drives the rotation motor 65, and the adherend WK is moved intermittently. Transport left. Then, the adherend WK is in a predetermined position, that is, the uppermost part of the adherend WK is a predetermined distance (for example, 5 mm, upstream from the first sticking position P1 in the transport direction). When detection means (not shown) such as an optical sensor or a camera detects that it has reached a distant position (substantially the same as the distance to the sticking position P1), the supply means 20 drives the rotating motor 24A and a drive device (not shown) to The adhesive sheet AS is fed out in accordance with the conveyance speed of the adherend WK, and the pressure roller 31 presses and attaches a part of the adhesive sheet AS to the adherend WK at the first sticking position P1. Thereafter, when the conveying means 60 conveys the adherend WK for one tact (the same distance as the interval between the adjacent sheet support rollers 64), the rotation motor 65 stops driving, and the uppermost portion of the adherend WK is the first. While stopping at a position advanced by a predetermined distance (for example, 10 mm) from the sticking position P1, the supply means 20 stops driving the rotating motor 24A and a driving device (not shown) in accordance with the stop timing. At this time, the front end region (part) of the adhesive sheet AS is adhered to the upper portion of the adherend WK, and the rear region is temporarily attached to the release sheet RL.

  When a predetermined time elapses, the transport unit 60 drives the rotation motor 65 again, and transports the adherend WK to the left by an intermittent operation. In synchronization with this conveying operation, the supply means 20 drives the rotation motor 24A and a driving device (not shown), feeds out the original fabric RS, and is positioned behind a set of support rollers 62B on which the adherend WK is placed. When the uppermost part of the support roller 64 passes through the first sticking position P1, the pressing roller 31 presses and sticks the rear region of the adhesive sheet AS to the sheet support roller 64. Thereafter, when it is detected by the detection means (not shown) that the leading end of the next adhesive sheet AS in the feeding direction has been peeled off by the peeling plate 23, the supply means 20 drives the rotation motor 24A and the driving device (not shown). When a part of the next adhesive sheet AS is pressed and pasted to another adherend WK to be transported next, and the transport means 60 transports the adherend WK by one tact, the transport means 60 is stopped. The supply means 20 stops driving the rotation motor 65, the rotation motor 24A, and a driving device (not shown). At this time, the adherend WK to which the adhesive sheet AS is affixed is positioned below the re-pressing roller 43 in the initial state as shown in FIG. 2, and the uppermost portion of the adherend WK, that is, the adhesive sheet AS is affixed. The made area stops at the second pasting position. Next, at the same time as or before and after the stop of the conveying means 60, the second pressing means 40 drives the rotation motor 42, rotates the re-pressing roller 43 by a predetermined angle in the clockwise direction, and rotates the adherend WK counterclockwise. The entire adhesive sheet AS is pressed against the outer periphery of the adherend WK by rotating in the direction. At this time, the re-pressing roller 43 gradually works to press the adhesive sheet AS against the outer periphery of the adherend WK by the R chamfer 43C following the non-pressing portion 43B, so that the adhesive sheet AS and the adherend WK The adhesive sheet AS can be affixed to the adherend WK in such a manner that air bubbles are not mixed between them and wrinkles are not generated in the adhesive sheet AS. At the same time as or before and after the rotation of the rotation motor 42, the urging unit 70 drives a pressure unit (not shown) and ejects air from the air nozzle 71, so that the adhesive sheet AS detached from the sheet support roller 64 is discharged. It is possible to prevent the rear area from adhering to the belt member 61 and the rear area of the adhesive sheet AS from adhering to the adherend WK first with respect to the area ahead of it. When the adherend WK to which the adhesive sheet AS is stuck is carried below the re-pressing roller 43, the detection means 50 detects the tip position of the adhesive sheet AS by the sensor 52, and the tip of the adhesive sheet AS is detected. If the detection timing of the adhesive sheet AS by the two sensors 52 does not fall within a predetermined time, the detection means 50 outputs a signal to a warning means such as a buzzer or a warning light (not shown) and the operator Or a predetermined process such as stopping the operation of the sheet sticking apparatus 10 by outputting a signal to a control means (not shown).

  Then, when a predetermined time has elapsed, when the conveying means 60 drives the rotation motor 65 again and conveys the adherend WK for one tact by an intermittent operation, the adherend WK with the adhesive sheet AS attached to the outer periphery thereof. Positioned below the unloading means 69 and stopped, the conveying means 60 drives the unloading means 69 and conveys the adherend WK to which the adhesive sheet AS is attached to another process or another apparatus. Is repeated. In the above description, the focus is on the adherend WK supported by one set of support rollers 62B. However, the same applies to other adherends WK supported by another set of support rollers 62B. Processing is performed.

  Further, the material, type, shape and the like of the adhesive sheet AS and the adherend WK in the present invention are not particularly limited. For example, the adhesive sheet AS is not limited to adhesive forms such as pressure-sensitive adhesiveness and heat-sensitive adhesiveness, and when a heat-sensitive adhesive is employed, a coil heater or heat for heating the adhesive sheet AS is used. Appropriate heating means such as the heating side of the pipe may be provided. Such an adhesive sheet AS is, for example, a single layer having only an adhesive layer, an intermediate layer between the base sheet and the adhesive layer, a cover layer on the upper surface of the base sheet, etc. Three or more layers, or a so-called double-sided adhesive sheet that can peel the base sheet from the adhesive layer may be used. The double-sided adhesive sheet comprises a single-layer or multi-layer intermediate layer. It may be a single layer or a multilayer having no intermediate layer. Examples of adherends include food, resin containers, semiconductor ingots such as silicon semiconductors and compound semiconductors, information recording substrates such as semiconductor wafers, circuit boards, and optical disks, glass materials, metal materials, ceramic materials, wood, and resins. It is also possible to target members and articles of any form such as materials. In addition, the adhesive sheet AS is replaced with a functional and intended reading, for example, any information label, decorative label, protective sheet, dicing tape, die attach film, die bonding tape, recording layer forming resin sheet, etc. Arbitrary shaped sheets, films, tapes, etc. can be attached to any holding object as described above.
