Description

Manufacturing method of film product, and manufacturing apparatus thereof

The present invention relates to a method for producing a plurality of film products from an optical film original sheet, and a production device for the film products.

Conventionally, optical films have been used in image display devices such as liquid crystal display devices and organic EL (Electroluminescence) display devices. As said optical film, the polarizing film containing a polarizing element, a retardation film, a light-diffusion film, etc. are mentioned. In addition, polarizing films and the like are also used for applications other than image display devices such as polarized sunglasses and light control windows. Such an optical film is formed into a specific plan view shape corresponding to its screen or the like so as to be assembled to the screen or the like of the above-mentioned image display device. In this specification, the optical film formed into a specific shape is called "film product". The film product is obtained by, for example, punching an optical film original sheet (a long strip-shaped optical film or a large-sized optical film) with a cutting knife, and then removing the cutting residue.

For example, Patent Document 1 discloses an apparatus in which a strip-shaped stub is peeled off while conveying a strip-shaped body, and a rod-shaped stripping member is arranged on the surface of the strip-shaped body at about 45 degrees with respect to the conveying direction, The strip-shaped stub is peeled off while inverting the strip-shaped stub (the strip-shaped cut residual part) in the direction of about 45 degrees from the peeling member.

Therefore, the circumferential direction of the pressing portion 41 , the non-pressing portion 42 and the guide portion 44 is the direction around the axis of the shaft rod 45 . The pressing parts 41 and the middle non-pressing parts 422 are alternately provided in the short-side direction of the optical film original sheet 1 , and the side non-pressing parts 421 are provided on both sides. The guide portions 44 are respectively disposed on both sides of each pressing portion 41 . The pressing portion 41 is arranged corresponding to the plurality of film products 9, the middle non-pressing portion 422 is arranged corresponding to the plurality of vertical strips 81 of the cutting residual portion 8, and the side non-pressing portion 421 is corresponding to the cutting residual portion. One pair of side longitudinal belts 811 are arranged correspondingly to each other.

The material of each surface of the pressing portion 41 , the non-pressing portion 42 and the guide portion 44 is not particularly limited, and can be independently exemplified by foamed resin, rubber (rubber includes elastomer), hard synthetic resin, soft synthetic resin, aluminum, Metals such as iron etc. In order not to damage the surface of the film product 9 , the surface of the pressing portion 41 is preferably formed of micro-foamed foamed resin, rubber, or soft synthetic resin, and especially, more preferably, formed of rubber. Furthermore, in the illustrated example, the shaft 45 also serves as the intermediate non-pressing portion 422 . That is, the peripheral surface of the shaft rod 45 constitutes the intermediate non-pressing portion 422 .

When each part is cylindrical, it is preferable to satisfy the relationship of diameter of pressing part 41>diameter of side non-pressing part 421>diameter of middle non-pressing part 422 from the viewpoint of diameter. In addition, in the case of having the guide portion 44 , the relationship of the diameter of the pressing portion 41 > the diameter of the guide portion 44 > the diameter of the intermediate non-pressing portion 422 is satisfied. The diameter of the cylindrical pressing portion 41 is not particularly limited, and can be appropriately set. The diameter of the pressing portion 41 is, for example, 30 mm to 100 mm, preferably 40 mm to 80 mm, and more preferably 50 mm to 60 mm. The length of the film product 9 refers to the length of the film product 9 in the longitudinal direction of the optical film original sheet 1 .

The diameter of the cylindrical intermediate non-pressing portion 422 is not particularly limited as long as it is smaller than the diameter of the pressing portion 41 . Since the separation point P2 easily moves to the upstream side, it is preferable that the diameter difference between the intermediate non-pressing portion 422 and the pressing portion 41 be as large as possible. The diameter of the middle non-pressing portion 422 is, for example, 5 mm to 40 mm.

The diameter of the side non-pressing portion 421 is not particularly limited on the condition that the above relationship is satisfied, but if it is too large or too small, it will be substantially the same as that of the pressing portion 41 or the middle non-pressing portion 422 . The diameter of the side non-pressing portion 421 is, for example, about 30 mm to 35 mm. The diameter of the guide portion 44 satisfies the relationship between the diameter of the pressing portion 41 > the diameter of the guide portion 44 > the diameter of the intermediate non-pressing portion 422 , and is not particularly limited. The guide portion 44 guides the vertical belt 81 to pass through the center portion of the middle non-pressing portion 422 (the middle portion of the adjacent pressing portion 41 ) when the cutting residual portion 8 is pulled up. By providing the guide portion 44, the longitudinal belt 81 of the cut residual portion 8 can be prevented from being bent during pulling.

As shown in FIG. 8, the pressing part 41 is arrange|positioned so that it may contact with the surface of the said film product 9 of the optical film original sheet 1 divided into the cutting residual part 8 and the film product 9. As described above, the original optical film sheet 1 is transported to the removal section D by the transport section B after being divided into the cutting residual section 8 and the film product 9 by the cutting processing section C. Specifically, the optical film original sheet 1 is conveyed to the downstream side in the state mounted on the belt conveyor 35 which is the conveyance part B. The pressing part 41 is arrange|positioned so that it may contact with the surface of the film product 9 of the optical film original sheet 1 in the middle of conveyance. In other words, the film product 9 is conveyed in the tangential direction of the peripheral surface of the pressing portion 41 while being in contact with the lower end of the pressing portion 41 . When the pressing part 41 is in contact with the surface, the conveyed film product 9 is pressed, so that it does not float up from the belt conveyor 35 serving as the conveying part B. Furthermore, "the pressing portion 41 presses the film product 9" does not mean applying a strong pressure, but means that the pressing portion 41 is attached to the film product 9 to such an extent that the film product 9 does not float when the cutting residual portion 8 is pulled out. the surface. Furthermore, since the horizontal belt 82 of the cut residual portion 8 is interposed between the film products 9 and 9 adjacent to each other in the longitudinal direction, the horizontal belt 82 of the transported optical film original sheet 1 and the film product 9 are separated. The surfaces are sequentially in contact with the pressing portion 41 .

As shown in FIG. 8, since the diameter of the intermediate non-pressing part 422 is smaller than that of the coaxial pressing part 41, it is spaced (not in contact) with the longitudinal belt 81 of the optical film original sheet 1 conveyed in the state of being placed on the conveying part B. Similarly, since the diameter of the side non-pressing portion 421 is smaller than that of the coaxial pressing portion 41, it is separated from the side longitudinal belt 811 (vertical belt 81) of the optical film original sheet 1 conveyed in the state of being placed on the conveying portion B (not touch). However, when pulling up the cutting residual portion 8, please note that the vertical strips 81 (including the side vertical strips 811) of the cutting residual portion 8 that has been pulled are connected to the non-pressing portion 42 (the middle non-pressing portion) as shown in FIG. 6 . 422 and the peripheral surface of the side non-pressing portion 421) are in contact.

The width 41W of the pressing portion 41 is smaller than the width 9W of the film product 9 . The reason for this is that if the width of the pressing portion 41 is larger than the width of the film product 9 , the pressing portion 41 protrudes from the film product 9 and interferes with the vertical belt 81 . The width 9W of the film product 9 (refer to FIG. 9 for symbol 9W) refers to the length of the film product 9 in the short-side direction of the optical film original sheet 1 . The width of the pressing portion 41 is not particularly limited as long as it is smaller than the width of the film product 9 . The width of the pressing portion 41 is, for example, 25 mm to 60 mm.

The pressing portion 41 may be configured to be rotatable around its axis, or may be non-rotatable. In order to prevent damage to the film product 9, the pressing portion 41 is preferably rotatable. The method of making the pressing portion 41 rotatable is not particularly limited. For example, the pressing portion 41 can be attached to the shaft 45 via a bearing, and when the shaft 45 is rotatable, the pressing portion 41 can be fixedly attached to the shaft. Axle 45 etc. Preferably, the pressing portion 41 is provided on the shaft 45 so as to be freely rotatable. The non-pressing portion 42 and the guide portion 44 may also be configured to be rotatable around the axis thereof similarly to the pressing portion 41, or may not be rotatable. Preferably, the side non-pressing portion 421 is provided on the shaft 45 so as to be freely rotatable. Moreover, the guide part 44 is provided integrally with the pressing part 41, for example, and similarly to the pressing part 41, it is provided in the shaft 45 so that it may become a freely rotatable state. Furthermore, in the present embodiment, the shaft 45 also serves as the intermediate non-pressing portion 422 , and therefore, whether or not the intermediate non-pressing portion 422 rotates depends on the shaft 45 .

In the illustrated example, the shaft 45 is fixed and supported by the bearing 46 . Therefore, the shaft 45 itself does not rotate, nor does the intermediate non-pressing portion 422 rotate. The non-pressing portion 42 and the side non-pressing portion 421 are provided on the shaft 45 in a freely rotatable state via a bearing (not shown).

＜Product Recycling Department＞ The product recovery section E has a recovery section 37 that recovers the film product 9 obtained by removing the cutting residue 8 in the removal section D described above.

[Manufacturing method of film product using manufacturing apparatus] The manufacturing method of the film product of the present invention conveys the optical film original sheet 1, and divides the in-plane of the optical film original sheet 1 into the optical film original sheet 1 that extends in the longitudinal direction by cutting the optical film original sheet 1 in-plane. The cut residual portion 8 of the plurality of longitudinal belts 81 and the plurality of transverse belts 82 extending in the short-side direction, and the film product 9 surrounded by the above-mentioned longitudinal belts 81 and transverse belts 82, after dividing the original optical film. While the sheet 1 is being conveyed to the downstream side, the film product 9 is pressed so as not to float up and the vertical belt 81 of the cut residual portion 8 is not pressed, and the cut residual portion 8 is pulled out and removed. By removing the cutting residue 8, only a plurality of film products 9 of a specific shape can be taken out.

1 , by the conveyance part B, the optical film original sheet 1 and the blade support sheet 2 are conveyed toward the downstream side in the longitudinal direction (conveyance step). In addition, the thin arrow of FIG. 1 shows the conveyance direction of the optical film original sheet 1 etc.. FIG. The optical film original sheet 1 is superimposed on the front surface of the knife support sheet 2 in the middle of conveyance, etc., and is conveyed to the cutting process part C in this state.

In the cutting process part C, the cutting blade 61 of the cutter device 6 is pressed against the above-mentioned optical film original sheet 1 from the opposite side (the front side) of the blade support sheet 2 (cutting step). By entering the cutting blade 61 in the thickness direction of the optical film original sheet 1 until the cutting edge of the cutting blade 61 reaches the blade supporting sheet 2, the optical film original sheet 1 can be punched into the same shape as the cutting blade 61 in plan view. shape. The blade supporting sheet 2 of the cutting processing section C has been wound up to the winding section 332 .

By cutting, the optical film original sheet 1 divided into the film product 9 and the cutting residual portion 8 as shown in FIG. 5 can be obtained. By the conveyance part B, the optical film original sheet 1 divided into the film product 9 and the cutting|disconnection residual part 8 is conveyed further downstream. When the optical film original sheet 1 divided into the film product 9 and the cut residual portion 8 is conveyed to the removal portion D, the cut residual portion 8 is pulled out by the separation member 71 and is wound on the recovery roller 72 (see FIGS. 1 and 6 ). ). In the removal portion D, the pressing portion 41 is brought into contact with the surface of the film product 9 to press the film product 9 so as not to float, and the cutting residual portion 8 is cut at approximately the same conveying speed as the original optical film 1 . speed to pull out. Specifically, as described above, the removal portion D is provided with the separation member 71 for separating the cut residual portion 8 from the film product 9 . The separating member 71 has a pressing portion 41 that presses the surfaces of the plurality of film products 9 and a non-pressing portion 42 that does not press the surface of the longitudinal belt 81 of the cutting residual portion 8 . Only the film product 9 can be taken out by pulling out the cutting residual portion 8 based on the separation member 71 described above. According to the present invention, the film product does not follow the cut residual portion 8 that has been pulled out, and only the cut residual portion 8 can be surely removed from the optical film original sheet 1 .

FIG. 11 shows the vertical belt 81 and the horizontal belt 82 of the cutting residual part 8 and the film product 9 , the pressing part 41 and the non-pressing part 42 (intermediate non-pressing part 422 ) in the process of pulling out the cutting residual part 8 . A side view for reference to illustrate the positional relationship. In FIG. 11, a thin oblique line from the upper left to the lower right of the paper is attached to the vertical strip 81 of the cut residual portion 8, and a thin oblique line from the upper right to the lower left of the paper is attached to the horizontal strip 82 of the cut residual part 8. The film product 9 is attached with thinner and thicker slashes.

[T1] in FIG. 11 indicates that the boundary between the upstream end portion 82a of the horizontal belt 82 and the downstream end portion 9a of the film product 9 (the boundary is a cutting line extending in the short-side direction) has reached the contact point of the pressing portion 41 At the time point P1, the figure [T2] shows a state in which the above-mentioned horizontal belt 82 is along the peripheral surface of the pressing portion 41 . In addition, in this specification, the "upstream side" means the side opposite to the conveyance direction of the optical film original sheet 1, and the "downstream side" means the conveyance direction side of the optical film original sheet 1. Since the cutting residual portion 8 has a plurality of vertical strips 81 extending continuously in the longitudinal direction, it can be pulled out without interruption. Since the pressing portion 41 is arranged corresponding to the film product 9 and the horizontal belt 82 , when the cutting residual portion 8 is pulled out, the horizontal belt 82 moves along the peripheral surface of the pressing portion 41 as shown in FIG. [T2]. When the horizontal belt 82 is at the position of [T1] in this figure, the point (referred to as a separation point) at which the cutting residual portion 8 and the film product 9 are separated is located on the contact point P1 of the pressing portion 41. When the horizontal belt 82 is slightly moved from the position of the drawing [T1] to the position of the drawing [T2], the separation point P2 described above moves toward the upstream side. Furthermore, as the horizontal belt 82 moves from the position [T2] to the position [T3] and from the position [T3] to the position [T4] in the drawing along the peripheral surface of the pressing portion 41, the separation point P2 moves further upstream. In this way, in the process of pulling out the cutting residual portion 8, the separation point P2 is moved to the upstream side of the contact point P1 of the pressing portion 41 pressing the film product 9, so that only the cutting residual portion 8 can be reliably pulled out. remove.

The pull-out angle α of the cutting remaining portion 8 is not particularly limited, but since the separation point P2 is easily moved to the upstream side, it is, for example, 90 degrees or less, preferably 80 degrees or less, and more preferably 70 degrees or less. The lower limit of the pull-out angle α is not particularly limited, but if it is too small, the cut residual portion 8 that has been pulled out may come too close to the original film sheet 1 conveyed by the conveying portion B. From the above viewpoint, the pull-out angle α of the cutting remaining portion 8 is, for example, 10 degrees or more, or preferably 20 degrees or more. As shown in FIG. 11 , the pull-out angle α of the cut residual portion 8 refers to the angle formed by the cut residual portion 8 and a plane parallel to the optical film original sheet 1 .

Moreover, since the side non-pressing part 421 is provided corresponding to the side part longitudinal belt 811 of the cutting residual part 8, the side part longitudinal belt 811 can be pulled out stably in the longitudinal direction. By being able to stably pull out the side longitudinal belts 811 , the cut remnants 8 with holes (missing traces of the film product 9 ) opened in various places can be stably pulled out and taken up on a recovery reel. Specifically, the cutting remainder 8 has holes in various places, but it can be considered to be the same as a long strip-shaped sheet in that the plurality of vertical strips 81 are continuous in the longitudinal direction. When the cutting residual portion 8 is pulled out while pulling the vertical belt 81, it can be pulled out stably. In this case, if the longitudinal belts 81 (a pair of side longitudinal belts 811 ) at least on both sides are pulled, the cutting residual portion 8 can be pulled out stably. Therefore, by arranging the side non-pressing portion 421 with a diameter larger than that of the middle non-pressing portion 422 corresponding to the side vertical belt 811, the side vertical belt 811 is not greatly deflected. Therefore, the cut residual portion 8 can be stably pulled out and taken up. Furthermore, since the diameter of the side non-pressing portion 421 is smaller than that of the pressing portion 41 , when the cutting residual portion 8 is pulled out, the film product 9 does not follow the side longitudinal belt 811 .

The film product 9 obtained by removing the cut residual portion 8 is conveyed by the belt conveyor 36 and recovered by the recovery portion 37 . The layer constitution of the obtained film product 9 is the same as that of the above-mentioned optical film original sheet 1 . When the film product 9 is composed of, for example, the optical film 11/adhesive layer 12/separator film 13, the film product 9 can be attached to any component (such as the screen of an image display device, etc.) by peeling off the release film 13. ). However, the film product 9 is not limited to the application used by being attached to an arbitrary member.
