Field of the Invention The present invention relates to a cutting apparatus for cutting a sheet of a plurality of optical films by a long optical film and an optical film producing method. [Prior Art] An optical film represented by a polarizing film and a phase difference film constitutes an important optical component of a liquid crystal display device. A long optical film, usually a raw material, is cut to produce an optical film using a cutting device. For this cutting device, high speed cutting of the optical film and excellent productivity and throughput are required. For example, Japanese Patent Laid-Open Publication No. 2004_1 8 8 5 5 2 discloses a sheet cutting apparatus comprising a raw material supply device, and a long sheet of the coil material supplied from the raw material supply device is cut into A cutting device having a sheet of a predetermined size, and a stacking device for stacking sheets cut by the cutting device. The cutting apparatus includes a rotary microtome that cuts the long sheet in a width direction by a predetermined width; and a shearing cutter (cutting machine) that longitudinally cuts the predetermined length in the width direction Long sheet. However, there is a problem in which the chips are easily produced by cutting with the cutting knife. When the long sheet of the optical film is cut using a sheet cutting device disclosed in Japanese Patent Application Laid-Open Publication No. 2004-185052, the chips are easily produced, and by the chips The resulting split is produced in an optical film surface to reduce productivity and yield. In the stacking device, when the optical film is held by a plurality of other optical film hooks-5-200846155, wherein the chips adhere to the surface of the optical film, the chips are buried in the optical film by the weight of the stacked optical film. This produces the split in the optical film. According to this, it is necessary to perform the cutting at a rate, wherein when the long sheet of the optical film is cut by the sheet cutting device disclosed in Japanese Patent Laid-Open Publication No. 2004-185 8 52, These chip systems are hardly produced. That is, the long-length optical film cannot be cut at a high speed by using a sheet cutting device disclosed in Japanese Laid-Open Patent Publication No. 2004-1885.

Figure 5 is an enlarged plan view showing the vicinity of the shooting drum of the first embodiment. As shown in FIGS. 1 and 2, the optical film cutting apparatus of the first embodiment continuously includes the upstream side along the transport direction of the long optical film 2 (direction of arrow A) transported from the material web 1. An optical film raw material roll 1, a slicer 1 〇, a transverse cutter 20, a separation conveyor 30, a pair of cleaning rolls 40 and 40, and a stacking unit 50. As shown in Fig. 3, the long optical film 2 carried by the material web 1 is cut in the direction in which the optical film is transported, and the plurality of optical films 4 can be cut by a slit optical film 3. Specifically, as shown in Fig. 2, in the optical film raw material roll 1, -10- 200846155, the long optical film 2 is wound around a transport shaft 1 & the transport shaft is a core material. Preferably, the transport shaft la is formed in a conical shape. Both ends of the transport shaft la are journaled in a pair of bearings ib and lb. As shown in FIG. ', the optical film 2 is transported at a constant speed from the raw material web 1 in the direction of the arrow a by a pair of transport rollers 16 and 16, and the microtome 10 is used for transporting the optical film. The long optical film 2 carried by the material web 1 is cut in a direction (direction of the arrow A) by a predetermined width. The microtome 10 includes a plurality of rotary blades u and a roller 12. The roller 12 is positioned below the rotary blade U, and the outer peripheral surface of the roller 12 contacts the cutting edge of the rotary blade 11 (see FIGS. 1 to 3). The plurality of rotary blades 11 are parallel. Is provided at an interval corresponding to the width of the cut sheet of the optical film 4, and the rotary blade is provided in a direction orthogonal to the · transport direction (that is, 90 degrees with respect to the transport direction) In the direction of the angle). The spacing between the rotary blades 11 can be arbitrarily selected according to the width of the sheet of the optical film 4. Usually, the interval is preferably set in the range of about 100 mm to about 1 200 mm, depending on the optical film. The number of sheets of 4 determines the number of rotary blades 11. The number of the rotary blades 11 is not limited to at least two, but only one rotary blade 11 can be used. The number of sheets of the optical film 4 preferably ranges from about two to about six, and the number of the rotary blades 11 ranges from about one to about five. -11 - 200846155 Considering this improvement in productivity, a so-called NC (digital control) slicer is preferably used as the slicer 10, wherein each rotary type is input when an input size is input through an operation panel The blade 11 is automatically positioned. The optical film 2 was cut by the microtome 1 to perform the following. The optical film 2 carried by the pair of transport rollers 16 and 16 in the direction of the arrow A is transported between the rotary blades 11 and the drum 12 of the slicer 10. The cutting edges of the rotary blades 11 press the transported optical film 2 against the outer peripheral surface of the drum 12, and the rotary blades 11 are rotated by the movement of the optical film 2. As a result, the optical film 2 is cut at a predetermined width (i.e., the interval between the rotary blades 11) in the transport direction. Preferably, trimming blades 13 and 13 are provided on the upstream side of the transverse cutter 20 in the conveying direction to cut the side edge portions 5 and 5 of the long optical film 2. Although the optical film 4 has various widths (i.e., is not fixed), the trimming blades 13 and 13 can be provided to easily correspond to the various widths. A cutter having the same structure as the rotary blade 11 can be cited as an example of the trimming cutters 13 and 13. A so-called edge trimming reel can be used. The side edge portions 5 and 5 of the cut optical film 2 are discharged toward a case 15 by a pair of discharge rolls 14 and 14. The transverse cutter 20 is used to cut the cut long optical film 3 in a direction orthogonal to the transport direction by a predetermined length. As shown in Fig. 4, the transverse cutter 20 is a rotary cutter including a blade cylinder 22 and a smooth roller 23. The blade cylinder 22 includes four blades 21, ..., 21 in the longitudinal direction at equal intervals 嗝 -12 - 200846155. The smooth surface roller 23 is positioned below the blade cylinder 22, and the outer peripheral surface of the smooth surface roller 23 contacts the cutting edge of the blade 21. Therefore, a transport rate is advantageously enhanced, and the blades 21 can be easily exchanged. The optical film 3 can be cut to the desired length by adjusting the rotational speed of the blade cylinder 22 in the transverse cutter 20. The cutting length of the optical film 3 can also be adjusted by the diameter of the blade cylinder 22 and the smoothing cylinder 23, and the number of blades 2 1 included in the blade cylinder 22. The rotation speed of the blade cylinder 22 and the diameter of the blade cylinder 22 and the smooth surface roller 23 are not particularly limited, but the rotation speed can be arbitrarily selected according to the cutting length of the optical film 3, that is, the sheet length of the optical film 4. The diameters. Preferably, the blade drum 22 has a rotational speed ranging from about 15 to about 600 revolutions per minute, and the diameter of the blade cylinder 22 ranges from about 50 mm to about 200 mm, and the diameter of the smooth roller 23 is The range is from about 1 mm to about 300 mm. The number of the blades 21 included in the blade cylinder 22 is not limited to four, but the number of the blades 2 1 may be arbitrarily selected from the range of one to ten, usually one to four. For example, the rotary cutter is disclosed in Japanese Patent Laid-Open Publication Nos. 06-3 04895 and 08-112798. The optical film 3 is cut by the transverse cutter 20 as follows. The cut long optical film 3 is transported between the blade roller 22 and the smooth roller 23 of the transverse cutter 20. Then, the edge of the blade 21 included in the blade cylinder 22 cuts the optical film 3' while being pressed against the outer peripheral surface of the smooth roller 23 by the optical film 3. As a result, the cut long optical film 3 is cut at a predetermined length in a direction orthogonal to the direction of the transport - 13 - 200846155 (i.e., in a direction having 90 degrees with respect to the transport direction). When the blade cylinders 22 are divided into four equal parts, the next optical film 3 is cut in the predetermined direction. The separation conveyor 30 is for separately conveying the sheets of the plurality of optical films 4 cut by the optical film 3 so that the sheets of the plurality of optical films 4 do not overlap. As shown in Figures 2 and 3, the separation conveyor 30 of the first embodiment includes a plurality of carrier belts 31, and the carrier belts 31 are disposed such that the spacing between the conveyor belts 31 adjacent to each other faces the The downstream side in the transport direction is widened to a predetermined interval. Therefore, even if the cut optical films 4 overlap each other, the optical films 4 are separately transported such that the interval between the optical films 4 adjacent to each other is widened toward the downstream side of the separation conveyor 30 in the transport direction to The predetermined interval, in other words, causes the optical films 4 not to overlap each other. More specifically, the interval between the conveyor belts 31 adjacent to each other is widened to a predetermined interval toward the downstream side in the conveying direction, so that the interval between the optical films 4 adjacent to each other is separated and transported in the conveying direction. The downstream side of the crucible 3 is widened to approximately 1.5 mm to approximately 2.5 mm. Although the number of the carrier belts 31 is not particularly limited, it is preferable to arrange the carrier belts 31 to 5 5 because the sheets of the plurality of optical films 4 are easily conveyed so as not to overlap each other. On the other hand, when overlapping each other, the sheets of the plural optical film 4 are carried unless the carrier belts 31 are arranged in a predetermined positional relationship. When the optical films 4 are transported and overlap each other, among the substances removed from the optical film 4 by the cleaning roller 14-200846155, a mark is attached to one portion of the optical films 4 overlapping each other. Produced in the portion which produces a split in the optical film 4. The separating conveyor 30 preferably includes a suction member that carries the optical film 4 while sucking the optical film 4 in the conveying direction. Therefore, the optical film 4 placed on the surface of the separation conveyor 30 is fixed so that the optical film 4 can be reliably conveyed at a high speed even if the optical film is curled.

The strong adhesive roller 42 is disposed to contact the weak adhesive roller 41, and the strong adhesive roller 42 has a stronger adhesive force than the weak adhesive roller 41. More specifically, an adhesive layer made of an acrylic resin is provided on the circumferential surface of each of the weak adhesive roller 4 1 and the strong adhesive roller 42. In the thin adhesive roller 4 1 , the adhesion of the material to the outside of the optical film 4 can be obtained by adjusting the thickness of the adhesive layer and the component of the acrylic resin being removed. In the strong adhesive roller 42, the foreign matter adhered to the optical film 4 of the weak adhesive roller 41 can be peeled off by the thickness of the adhesive layer and the composition of the acrylic resin, and the weak adhesive roller is removed. The degree of removal of 41 gives the adhesion. The foreign matter adhered to each of the optical films 4 by the pair of cleaning rollers 40 and 40 is carried out as follows. When the optical film 4 that is separately transported so as not to overlap each other is transported between the weakly adhesive rollers 41 and 41 of the pair of cleaning rollers 40 and 40, the substance adhered to the outside of the optical film 4 is attached thereto. The weakly adherent rollers 4 1 and 4 1 are removed and the foreign matter is removed by the optical film 4. Then, the weak adhesive rollers 41 and 41 are rotated by the movement of the optical film 4, and the strong adhesive rollers 42 and 42 are also rotated according to the weak adhesive rollers 4 1 and 41. Rotate. Therefore, the substances adhered to the weakly adherent rollers 4 1 and 4 1 are adhered to the strong adhesive rollers 42 and 42, and the foreign substances are removed by the weakly adherent rollers 4 1 and 41. The surface of the weakly adherent rollers 4 1 and 4 1 is always kept clean. A conveyor 45 carries the optical films 4, wherein the foreign matter is removed to the stack. As shown in Figures 2 and 3, the carrier 45 of the first embodiment includes a plurality of carrier belts 46 for aligning the optical film 4 from which the foreign matter has been removed for easy transport.

The optical film 6 can be reduced by a small amount of the blade 2 2 1000 rpm, and t to about 50,000 = the position of the optical film is detected to be 72 to the transport roller J optical film 2. The bar code is exclusively read by the bar code - 21 - 200846155. Then, the control unit 90 continuously drives the transverse cutter 20 and the discharge mechanism 80 based on the detection result from the defect mark detection unit. Under the control of the control unit 90, the transverse cutter 20 cuts the optical film including the depressed portion 71 into a predetermined length. Then, the discharge member 80 is driven upward with respect to the feed direction while being concentrated around the shaft center 82a of the drum 82 under the control of the control unit 90, and the discharge member 80 will be included by the transverse cutter 20 The defective portion of the cut 7 1 is discharged toward a box 85. Since the other components are similar to those of the first embodiment, the description is not given. While the invention has been described with respect to the specific embodiments thereof, the invention is not limited to the specific embodiments, but various changes and modifications may be made without departing from the scope of the invention. For example, the microtome includes the rotary blades of the specific implementations. Since the optical film cutting apparatus of the present invention includes the removing drum, the cutting cutter (shearing machine) can be used instead of the rotary blade.
