The operation of the above sheet sticking apparatus EA will be described.
First, a user (hereinafter simply referred to as “user”) of the sheet sticking apparatus EA, as shown in FIG. Then, an operation start signal is input to the sheet sticking device EA via an operation unit (not shown) such as an operation panel or a personal computer. Then, the feeding means 10 and the collecting means 40 drive the rotation motors 13A and 41A, and the raw fabric RS is fed and the leading adhesive sheet AS is peeled at the peeling edge 20A of the peeling plate 20 as shown by the solid line in FIG. When the sheet RL is peeled from the sheet RL by a predetermined length, the driving of the rotation motors 13A and 41A is stopped, and the sheet sticking device EA enters a standby state.

  Next, when a conveying means (not shown) such as a user or an articulated robot or a belt conveyor places the adherend WK on the support table 52, the moving means 50 drives a decompressing means (not shown), and the supporting surface 52A Adsorption holding of the adherend WK is started. Thereafter, the moving means 50 drives the linear motor 51 to move the support table 52 to the left, and when the adherend WK reaches a predetermined position, the feeding means 10 and the collecting means 40 move the rotation motors 13A and 41A.

Thereby, as shown by a two-dot chain line in FIG. 1, the adhesive sheet AS is peeled off from the release sheet RL at the release edge 20 </ b> A of the release plate 20, and is pressed onto the upper surface of the adherend WK by the pressing roller 30. Is done.

  When the entire adhesive sheet AS is affixed to the adherend WK and the next adhesive sheet AS is peeled from the release sheet RL by a predetermined length at the peeling edge 30A, the feeding means 10 and the collecting means 40 are connected to the rotation motors 13A and 41A. The driving is stopped, and the sheet sticking device EA enters the standby state again. 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 30, the moving unit 50 stops driving the linear motor 51 and a decompressing unit (not shown). Then, after 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 moving means 50 drives the linear motor 51 to return the support table 52 to the initial position. Thereafter, the same operation as described above is repeated.

Here, the feeding unit 10 and the moving unit 50 cooperate with each other, and during the spanning period in which the adhesive sheet AS is straddled between the release sheet RL and the adherend WK, the feeding roller 13 is fed in the feeding direction of the original fabric RS. A predetermined tension FC is applied to the adhesive sheet AS while rotating the adhesive sheet AS.

During the straddling period until the rear end ASR in the feeding direction is separated from the release sheet RL, the moving means 50 keeps the torque of the linear motor 51 that moves the support table 52 constant, and the feeding means 10 moves the feeding roller 13 to the original fabric. The torque or speed of the rotation motor 13A that rotates in the RS feeding direction is controlled to apply a predetermined tension to the adhesive sheet AS. Thereby, the adhesive sheet AS is stuck to the adherend WK in a state where a predetermined tension is applied.
In the case of the present embodiment, the feeding means 10 and the moving means 50 cooperate with each other, and during the straddling period, the feeding means 10 rotates the torque of the rotation motor 13A that rotates the feeding roller 13 in the feeding direction of the original fabric RS. While keeping constant, the moving means 50 may control the torque or speed of the linear motor 51 for moving the support table 52 to apply a predetermined tension to the adhesive sheet AS, or during the straddling period, the moving means 50 may support the support table 52. 52, the speed of the linear motor 51 is kept constant, and the feeding means 10 controls the torque or speed of the rotation motor 13A that rotates the feeding roller 13 in the feeding direction of the original fabric RS, so that a predetermined tension is applied to the adhesive sheet AS. During the straddling period, the feeding means 10 keeps the speed of the rotating motor 13A that rotates the feeding roller 13 in the feeding direction of the original fabric RS, and moves. And controlling the torque or speed of the linear motor 51 that stage 50 moves the support table 52, may be applied a predetermined tension to the adhesive sheet AS.

Further, the feeding means 10 and the moving means 50 cooperate with each other, and are applied to the adhesive sheet AS according to the length (length in the front-rear direction) of the adhesive edge AS1 where the adhesive sheet AS adheres to the adherend WK. The tension is increased or decreased.
That is, in the feeding unit 10 and the moving unit 50, for example, the tension applied to the adhesive sheet AS is controlled so that the tension per unit length of the adhesive edge AS1 is constant, and the length of the adhesive edge AS1 is doubled. Then, the relationship between the length of the adhesive edge AS1 and the tension applied to the adhesive sheet AS is controlled to be a direct proportional relationship so that the tension applied at that time is doubled. With such a configuration, the feeding means 10 and the moving means 50 can be used for the adhesive sheet AS even if the shape of the adhesive sheet AS is, for example, a circle, a triangle, a quadrangle, or more polygons, an ellipse, or other shapes. The AS can be applied to the adherend WK with uniform tension.

The sheet pasting device EA again enters a standby state after the stage before the straddling period until it is pasted to the adherend WK and the trailing end ASR in the feeding direction of the adhesive sheet AS is separated from the release sheet RL. In at least one of the stages after the straddling period, the collecting means 40 keeps the torque of the turning motor 41A for rotating the feed roller 41 constant, and the turning means for rotating the feeding roller 13 by the feeding means 10 The torque or speed of 13A is controlled, and a predetermined tension is applied to the release sheet RL. Thereby, peeling sheet RL can be collect | recovered appropriately.
In the case of the present embodiment, the feeding means 10 and the collecting means 40 cooperate with each other, and in at least one of the stage before the straddling period and the stage after the straddling period, the feeding means 10 feeds the feeding roller 13. The torque of the rotation motor 13A that rotates the rotation roller 13A may be kept constant, the collection means 40 may control the torque or speed of the rotation motor 41A that rotates the feed roller 41, and a predetermined tension may be applied to the release sheet RL. In at least one of the stage before the straddling period and the stage after the straddling period, the collecting means 40 keeps the speed of the rotation motor 41A for rotating the feed roller 41 constant, and the feeding means 10 feeds the feeding roller 13. The torque or speed of the rotation motor 13A that rotates the motor may be controlled, and a predetermined tension may be applied to the release sheet RL. In at least one of the stages after the feeding period, the speed of the rotating motor 13A for rotating the feeding roller 13 by the feeding means 10 is kept constant, and the rotating motor 41A for rotating the feeding roller 41 by the collecting means 40 is maintained. A predetermined tension may be applied to the release sheet RL by controlling the torque or speed.
