On the outer circumferential surfaces of the first adsorption plate 1 and the second adsorption plate 4, a plurality of holes 1-1 and 4-1 are processed as shown in FIG. 5 to adsorb the film through the holes. . In addition, since one end surface of each adsorption plate (1, 4) is located in the movement path of the film to be described later, it is preferable to process in a round shape in order to facilitate the transfer of the film. Near the opposite end of the rounded end of the first suction plate 1, a recessed groove 1-2 is provided.

The pressing roller 5 is located in the vicinity of the second suction plate 4. Many holes 5-1 are processed also on the surface of the crimping roller 5, and can adsorb | suck a film. As described above, the film transferred by the second adsorption bar 13 moves to the d position of FIG. 2, and then the adsorption is stopped when the second adsorption bar 13 moves to the e position while the adsorption bar 13 stops adsorption. The film is adsorbed to the pressing roller by the suction force of the pressing roller 5.

The pressing roller is in close contact with the inner circumferential surface of the cylindrical object to be adhered while adsorbing the film and serves to attach the adsorbed film to the inner circumferential surface of the cylinder. This will be described later.

In addition, when the adhesive is applied to the film, the ultrasonic cutting method that can avoid direct contact in order to prevent the cutting edge is contaminated with the residual material of the adhesive is more preferable.

Each component of the film attachment device according to an embodiment of the present invention may be arranged in a vertical direction but may be arranged horizontally. In other words, when placed vertically, the film can be attached to the cylindrical inner circumferential surface supplied in the form of lying down.

Hereinafter, a method of attaching a film to an inner circumferential surface of a cylindrical shape using the film attaching device according to another preferred embodiment of the present invention will be described.

The film attaching method according to the present invention comprises the steps of: supplying the film in the film supply device, transferring the film to the film winding device by the film transport device, winding the film by the film winding device, and the film winding device And pressing and attaching the film to the inner circumferential surface of the object to be bonded using a roller.

9A illustrates a film transfer device 10, a film cutting device 20, and a film winding device 9 that form a main portion together with a film supply device (not shown) among components of a film attachment device according to an embodiment of the present invention. ) Is shown briefly.

Referring to FIG. 9A, a film is supplied between the space formed by the film cutting device 20 and the first adsorption bar 11 to be lowered slightly below. In this state, the pressure roller rail 3 is moved in the direction of the arrow as shown in Fig. 9B so that the pressure roller 2 is located at a point where the conveyance of the film does not interfere. Subsequently, the first adsorption bar 11 at the a position starts adsorption and moves the film while moving to the b position of FIG. 9C along the rail 12 in the state of adsorbing the film. When the first adsorption bar 11 moves to the b position, the second adsorption bar 13 then starts adsorption at the c position. When the second adsorption bar 13 starts adsorption, the first adsorption bar 11 stops adsorption and returns to the a position (FIG. 9D), and the second adsorption bar 13 moves to the d position while maintaining adsorption. (FIG. 9E). Thereafter, when the pressing roller 5 starts adsorption while the second adsorption bar 13 stops adsorption and moves to the e position, the conveyed film is adsorbed on the pressing roller 5 as shown in FIG. 9F. In addition, when the second adsorption plate 4 starts adsorption, the transferred film is adsorbed on the second adsorption plate 4. The second adsorption bar 13, which transfers the film to the pressing roller 5, is returned to the original point c.

Next, the pressure roller rail 3, which has been moved in the direction of the arrow in FIG. 9B, is moved between the first adsorption plate 1 and the second adsorption plate 4 in the direction of the arrow in FIG. 9G. At this time, it is important that the second adsorption plate 4 and the pressing roller 5 maintain the tension of the film to be continuously wound. The length of the film wound on the film winding unit varies depending on how much the pressure roller rail 3 is moved. The length of the circumference of the cylindrical inner circumferential surface varies according to the size of the cylindrical inner circumferential surface, and accordingly, the length of the film to be attached is changed so that the degree of movement of the pressure roller rail 3 can be adjusted to cope with a change in the size of the cylinder within a predetermined range. . 10A and 10B are views for comparing the case where the winding is completed by changing the position of the pressure roller 2.

After the pressing roller 2 is moved corresponding to the required length as shown in FIG. 9H, the winding unit disc 7 is moved along the winding unit rail 6 in the direction of the arrow as shown in FIG. 9I. At this time, one side of the film is adsorbed by the first adsorption plate (1) and the other side is maintained in tension by the guide roller 23 of the film cutting device (20). Subsequently, as shown in FIG. 9J, the cutting groove 1-2 of the first adsorption plate 1 is moved to a position corresponding to the cutting edge 24 of the film cutting device 20 and then cut (FIG. 9K). . This completes the process of winding the film into the film winding unit 8. After winding the film, the winding unit disk 7 moves along the winding unit rail 6 to the place where the cylindrical inner circumferential surface to which the wound film is attached is located (FIG. 9L). At this time, the film is moved while being adsorbed by the first adsorption plate 1, the second adsorption plate 4, the pressing roller (5).

As described above, the film of the predetermined length wound in the film winding unit 8 is moved to the place where the cylindrical inner circumferential surface is located and introduced into the cylinder (FIG. 11A). The winding unit 8 introduced into the cylinder moves in the direction of the arrow so that the film adsorbed on the pressing roller 5 can come into contact with the cylindrical inner circumferential surface 40. When the film adsorbed to the pressing roller 5 is attached to the cylindrical inner circumferential surface 40 as shown in FIG. 11B, the film is continuously attached while rotating the winding unit 8 starting from this point (FIGS. 11C, d, e, f). At this time, it is important to simply rotate the winding unit 8 in attaching the film and push it so that sufficient pressure is applied to the cylindrical inner circumferential surface 40. As the film is attached to the inner circumferential surface, the wound film is pulled down and the length of the remaining film is reduced, and tension is maintained by the adsorption force of the adsorption plate, thereby enabling wrinkle-free attachment. If the first rotation to the point where the first attachment is started, all the film wound on the winding unit 8 is attached to the cylindrical inner peripheral surface (40). In the case where the adhesion force is insufficient by only one attachment using the pressing roller 5, as shown in FIG. 12, the pressure roller 2 is moved to the cylindrical inner circumferential surface 40 to further rotate by applying a strong pressure. Strong adhesion can be achieved. On the other hand, when the film to be attached is attached by heating and pressing, for example, such as a dry film, it may have the effect of heating and pressing by operating the heating means built in the pressure roller.

In addition, the jig holding the cylindrical inner circumferential surface relative to the rotation of the winding disk can be relatively moved in order to improve the adhesion performance.

Although the above has been described in detail with reference to the drawings and apparatus for attaching the film according to the preferred embodiment of the present invention, this is only for the purpose of description and the scope of protection of the present invention is not limited to the above-described embodiment, It will be apparent to those skilled in the art that many modifications are possible within the scope of the technical idea of the invention.
