It has a function to determine conditions and control them. The control means 24 is connected to each device to be controlled by a lead wire (not shown), a wireless structure, or the like.

  Next, a method for sticking the adhesive sheet S by the sheet sticking apparatus 10 will be described.

  As an initial operation, the original fabric R supported by the support shaft 27 is pulled out by a predetermined length, passed between the brake roller 28 and the pinch roller 29, and hung around the first dancer roller 60 and the guide rollers 30, 31, and 35. Then, the raw fabric R that has passed through the guide roller 35 is folded back at the tip of the peeling plate 14, hung around the guide rollers 36 and 32, the second dancer roller 61, and the guide roller 33, and then between the drive roller 37 and the pinch roller 38. And the lead end of the original fabric R is fixed to the winding shaft 42.

  When an operation signal is input from an input means (not shown), the motors M1 to M3 are driven to feed out the original fabric R, and when the leading edge of the adhesive sheet S is peeled from the release sheet RL by a predetermined length by the release plate 14, The leading edge detection sensor (not shown) detects the leading edge of the adhesive sheet S, the feeding of the raw material R is stopped, and a standby state is set.

  When the adherend W is conveyed leftward by the conveying means CV, it is detected by the detecting means 21 and the length detecting means 22, and the detection result is output to the control means 24. In the control means 24, the length detection means 22 is blocked by the height of the adherend W, that is, the position of the adherend surface Ws, as well as the adherend transport speed and the adherend W of the transport means CV inputted in advance. From the obtained time, the length in the transport direction of the adherend W and the position where the adhesive sheet S is attached to the transport direction are obtained.

  Thereafter, the control means 24 displaces the peeling plate 14 in the vertical direction via the linear motor 51 in accordance with the height of the adherend W, and presses the adhesive sheet S against the adherend surface Ws by the pressing roller 18. It waits in the press preparation position for doing. The pressing preparation position is a position where the adherend surface Ws passes in the left-right direction between the position of the peeling edge 14A and the lowest position of the pressing roller 18 positioned below the peeling edge 14A. When the peeling plate 14 is displaced, the motors M1 and M2 are locked, and the first and second dancer rollers 60 and 61 are displaced by the linear motor 64. That is, when the peeling plate 14 is displaced by a distance L from the position indicated by the solid line in FIG. 1 to the position indicated by the two-dot chain line, the original fabric R located in the upstream section between the peeling edge 14A and the support shaft 27. (Release sheet RL) is given a tension greater than or equal to a predetermined value to create a “tension”. From the position indicated by the solid line in FIG. 1 to the position indicated by the two-dot chain line in FIG. The “tension” is removed by displacing the distance by L / 2. Further, when the peeling plate 14 is displaced in the same manner as described above, the raw fabric R (peeling sheet RL) located in the downstream section between the peeling edge 14A and the take-up shaft 42 is also "tensioned" similarly to the upstream section. However, the second dancer roller 61 is displaced by a distance L / 2 from the position indicated by the solid line in the drawing to the position indicated by the two-dot chain line, thereby removing the “tension”. .

  When the peeling plate 14 completes waiting at the pressing preparation position, the linear motion motor 64 is locked, and the locked state of the motor M1 is released, so that a predetermined tension is applied to the original fabric R via the brake roller 28. Controlled.

Then, when the adherend W is transported leftward in FIG. 1 by the transport means CV, and it is detected by a sensor (not shown) that the leading end position of the adherend W has reached just below the peeling edge 14A. The time until the motor M2 is actuated is counted by the control means 24. When a predetermined time has elapsed, the motor M2 is actuated to feed out the original fabric R at the same speed as the conveyance speed of the adherend W.
Here, for example, when the attachment position of the adhesive sheet S is set to the center in the conveyance direction of the adherend surface Ws, the length in the feeding direction of the adhesive sheet S is subtracted from the length in the conveyance direction of the adherend W, and the subtraction is performed. The motor M2 may be operated when the adherend W advances a distance corresponding to half of the distance. The length in the feeding direction of the adhesive sheet S can be input in advance to the control means 24 from an operation panel (not shown). By feeding the original fabric R, the adhesive sheet S is peeled off by the peeling plate 14, supplied between the adherend W and the pressing roller 18, pressed by the pressing roller 18, and stuck on the adherend surface Ws. The In addition, as shown by a solid line and a two-point difference line in FIG. 1, the adhesive sheet S peeled off by the peeling plate 14 is maintained at a constant feeding angle θ with respect to the adherend surface Ws. Thus, the adhesive sheet S can be applied to the adherend surface Ws with the application condition of the adhesive sheet S constant, and the application of the adhesive sheet S can be stabilized.

  When the application of the adhesive sheet S is finished, the raw fabric R is fed out until the leading edge of the next adhesive sheet S is detected by a leading edge detection sensor (not shown), and the same operation as described above is repeated. Here, conversely to the previous case, when the peeling plate 14 is displaced by a distance L from the position indicated by the two-dot chain line in FIG. 1 to the position indicated by the solid line, the upstream section between the peeling edge 14A and the support shaft 27 is obtained. In the original fabric R (peeling sheet RL) located in the downstream section between the peeling edge 14A and the winding shaft 42, "slack" is produced, but the first dancer roller 60 and the second dancer roller 61 are the same. The “slack” is removed by shifting the distance L / 2 from the position indicated by the two-dot chain line in the figure to the position indicated by the solid line.

  Therefore, according to such an embodiment, only the minimum members necessary for attaching the adhesive sheet S such as the peeling plate 14 and the pressing roller 18 are displaced by the linear motion motor 51 without displacing the feeding means 12 and the like. Therefore, the weight of the member to be displaced can be reduced, and the linear motor 51 can be reduced in size and energy can be saved.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
In other words, the present invention has been illustrated and described mainly with respect to specific embodiments, but without departing from the scope of the technical idea and object of the present invention, the shape, position, or With respect to the arrangement and the like, those skilled in the art can make various changes as necessary.
Therefore, the description limited to the shape disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

For example, in the above-described embodiment, the displacement means 19 is configured to displace the pressing roller 18 together with the peeling plate 14. However, the displacement means 19 may be configured to displace only the peeling plate 14. In this case, the adhesive sheet S is peeled off by the peeling plate 14 and then bent by the feeding angle θ, whereby the elastic restoring force of the adhesive sheet S itself acts in the direction of the adherend W, whereby the adherend W Therefore, it becomes possible to adhere to the adherend W. In addition, you may arrange | position separately the press means which presses and adheres the adhesive sheet S to the to-be-adhered body W by ejecting a press roller or compressed air downstream of the peeling plate 14 in the to-be-adhered body conveyance direction.
Furthermore, in the said embodiment, although the peeling plate 14 was raised / lowered automatically from the detection data of the detection means 21, when the thing with the same height of the to-be-adhered body W is conveyed by the conveyance means CV, a detection means Instead of adopting 21, the displacement means 19 may be manually moved up and down and fixed at a predetermined position. In this case, the feeding auxiliary means 20 may be moved up and down manually, or may be configured to move up and down a half of the displacement amount of the peeling plate 14 via an appropriate link mechanism or the like.
In the above embodiment, the first and second dancer rollers 60 and 61 are lifted and lowered by the single linear motion motor 64. However, the first and second dancer rollers 60 and 61 are lifted and lowered by independent linear motion motors, respectively. Also good.
Further, the linear motion motor 64 has a single or independent linear motion motor as a torque-sensitive motor in addition to the configuration in which the linear motion motor 51 is moved up and down in synchronization with the movement of the linear motion motor 51. It is good also as a structure which raises / lowers the 1st, 2nd dancer rollers 60 and 61 by tension fluctuation | variation.
Moreover, in the said embodiment, although the case where the peeling plate 14 was raised / lowered was illustrated, the peeling plate 14 may be displaced to the left-right direction according to the width direction orthogonal to the conveyance direction of the to-be-adhered body W. Depending on the configuration of the adherend surface of the adherend, it may be displaced in an oblique direction.

  The drive device in the embodiment includes an electric device such as a rotation motor, a linear motion motor, a linear motor, a single-axis robot, and an articulated robot, an actuator such as an air cylinder, a hydraulic cylinder, a rodless cylinder, and a rotary cylinder. In addition to these, a combination of them directly or indirectly may be employed (some of them overlap with those exemplified in the embodiment).
