  SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its problem is to provide a plate-shaped article storage case having a simple configuration and capable of easily storing a plate-shaped article, and a plate-shaped article transfer for storing the same. It is providing the manufacturing method of an trolley | bogie and an optical display apparatus using these.

In order to solve the above problems, a plate-shaped article storage case according to the present invention is:
A plate-like case body having a placement surface for placing a square plate-like article;
The case main body is provided with guide protrusions for guiding the four corners of the rectangular plate-shaped article.

  The plate-shaped article storage case includes a plate-shaped case main body having a mounting surface on which the rectangular plate-shaped article is mounted, and the rectangular plate-shaped article can be mounted on the mounting surface in a stacked state. it can. Further, the case main body is provided with guide protrusions for guiding the four corners of the rectangular plate-shaped article, and the rectangular plate-shaped article can be smoothly placed using this. Moreover, since it guides the four corners of the rectangular plate-shaped article, it can also have a positioning function for the rectangular plate-shaped article. Thus, since it is the structure which only provides the protrusion part for a guide in a case main body, it can be set as a simple structure, and the plate-shaped article storage case which can perform the accommodation operation | work of a plate-shaped article easily can be provided.

In order to solve the above problems, another plate-shaped article storage case according to the present invention is as follows.
A plate-like intermediate support having a first placement surface on which a rectangular plate-like article is placed;
A first guide protrusion provided on the intermediate support for guiding the four corners of the rectangular plate-shaped article;
A plate-like case body having a second placement surface on which the intermediate support is placed;
The case main body is provided with a second guide protrusion for guiding the intermediate support.

  The plate-shaped article storage case is not placed directly on the case body, but is placed via a plate-shaped intermediate support. That is, the plate-like article is once stacked and placed on the intermediate support, and this intermediate support is further placed on the placement surface of the case body. Since the intermediate supporting body is provided with the first guide protrusions for guiding the four corners of the rectangular plate-shaped article, the rectangular plate-shaped article can be smoothly guided and positioned. Further, the intermediate support on which the rectangular plate-shaped article is placed is further smoothly guided and positioned by the second guide protrusion provided on the case body. By providing the intermediate support, it is possible to deal with rectangular plate-like articles of various sizes. That is, the intermediate support according to the size of the rectangular plate-shaped article can be used by preparing a plurality of the intermediate guides where the first guide protrusions are formed according to the size. Therefore, it is possible to provide a plate-shaped article storage case that can easily cope with various types.

  In the present invention, it is preferable that the guide surface of the guide protrusion is subjected to a surface treatment that reduces a friction coefficient.

  By performing such a surface treatment, it is possible to further facilitate the work for housing the rectangular plate-shaped article.

  In the present invention, it is preferable that an engagement portion is formed on the back side of the case main body so that the front end of the guide protrusion of the other case main body can be engaged.

  By providing such an engaging portion on the back side of the case main body, the plate-shaped article storage cases storing the rectangular plate-shaped articles can be stacked in the vertical direction, and the convenience during transfer can be improved.

  In the present invention, it is preferable to perform vacuum packaging after the rectangular plate-shaped article is accommodated in the case body. Thereby, while protecting a square plate-shaped article from dust, it can prevent that a square plate-shaped article absorbs water and changes during transfer.

  In this invention, it is preferable that the adsorption sheet is stuck on the mounting surface which mounts a square plate-shaped article. Thereby, at the time of transfer, it can prevent that a square plate-shaped article moves on a mounting surface, and can transfer a square plate-shaped article in a stable state.

In order to solve the above problems, a cart for transferring a plate-like article according to the present invention is as follows.
A rack body having a storage space for storing a plate-shaped article storage case according to the present invention storing a rectangular plate-shaped article;
A cart body having a support frame and wheels;
The rack body is supported on a support frame of the carriage body via a vibration absorbing mechanism.

  According to this configuration, the plate-shaped article storage case can be stored and transferred in the storage space provided in the rack body. The rack body is supported on the support frame of the carriage body via a vibration absorbing mechanism, and the vibration during transfer is hardly transmitted to the plate-shaped article storage case. Thereby, the damage to the square plate-shaped article which is a product can be prevented.

In order to solve the above problems, a method for manufacturing an optical display device according to the present invention includes:
A supply step of pulling out and supplying the belt-like sheet-shaped product from the roll around which the belt-shaped sheet-shaped product having the optical film which is a member of the optical display device is wound;
A detection step of detecting defects in the belt-like sheet product drawn out by the supply step;
A cutting process for cutting the strip-shaped sheet-shaped product based on the detection result in the detection process, and processing into individual rectangular plate-shaped articles,
A transfer step of transferring the rectangular plate-shaped article cut in the cutting step by the plate-shaped article storage case of the present invention or the plate-shaped article transfer carriage of the present invention;
The sheet-like product transferred in the transfer step and a bonding process step of bonding the optical display unit as a member of the optical display device are included.

  The operation and effect of the method of manufacturing the optical display device having this configuration will be described. The optical display device includes at least an optical film and an optical display unit. The strip-shaped sheet-shaped product has at least an optical film layer, and further includes, for example, a protective film layer. The belt-like sheet-like product has a long shape and is wound up on a roll. The belt-like sheet-like product in a form wound on this roll is drawn out, and for example, it is detected by a detection means whether there is a defect such as dirt, scratches, cracks or the like.

  Based on the detection result, the band-shaped sheet-shaped product is cut into a predetermined size by the cutting processing means. The “predetermined size” depends on the product size of the optical display device. When it is determined that there is a defect as a result of the detection, the cutting processing unit is controlled to cut into a predetermined size so as to avoid the defect, for example. Next, the cut rectangular plate-shaped article is transferred by a transfer means in order to perform a laminating process. In this transfer, the plate-shaped article storage case and the plate-shaped article transfer carriage described above are used. Therefore, it is possible to simplify the construction as described above and to easily accommodate the plate-shaped article. The transferred rectangular plate-shaped article and the optical display unit are bonded together by a bonding processing means.

  A preferred embodiment of a plate-shaped article storage case and a plate-shaped article transfer carriage according to the present invention will be described with reference to the drawings. As a specific example of the rectangular plate-shaped article, an optical film such as a polarizing plate will be described as an example.

The guide protrusion 11 is formed as an L-shaped protrusion in plan view and has a protrusion amount corresponding to the height of the optical film P to be accommodated. The cassette 10 has a placement surface 10a on which the optical film P is placed, and the optical film P is accommodated in the guide projection 11 in a form in which several sheets or several dozen sheets are directly laminated. The guide protrusion 11 can guide the optical film P when it is accommodated, and can also perform positioning.

  The cassette 10 and the guide projection 11 can be made of an appropriate material. For example, the cassette 10 and the guide protrusion 11 may be integrally molded with resin, or both may be separately manufactured and combined. Therefore, the cassette 10 and the guide protrusion 11 can be formed of a metal such as stainless steel, a synthetic resin, or the like. Further, the frictional resistance can be lowered by subjecting the guide surface of the guide projection 11 to a surface treatment with a fluorine resin or the like. Thereby, since the catch etc. do not arise when accommodating the optical film P, it can put in smoothly. The optical films P may be put one by one or may be stored in advance.

Provided. Therefore, the jig 20 in a state in which the optical film P is stacked and accommodated can be further accommodated in the cassette 10. Thus, the optical film P of various sizes can be handled by using the jig 20. That is, many jigs 20 can be prepared according to the size of the optical film P.

  The material of the cassette 10 and the jig 20 can be the same as in the first embodiment. The guide protrusions 11 and 21 can also be subjected to a surface treatment for reducing the frictional resistance as in the first embodiment. Moreover, after accommodating the optical film P, it is preferable to perform vacuum packaging.

<Guide protrusion>
FIG. 3 is a view showing another embodiment of the guide projection 11 (21), and a corner 11a (12a) is provided at the corner. Thereby, the corner | angular part of the optical film P to accommodate can be accommodated in the stable state, without being caught in a corner part.

<Adsorption tape>
FIG. 4 is a configuration example in which the suction tape 13 is attached to the placement surface 10a of the cassette 10 in the plate-shaped article storage case 1 of the first embodiment. By providing the suction tape 13, the optical film P can be held so as not to move even if it receives vibration during transfer. On the placement surface 10a, the position where the suction tape 13 is provided, the size of the suction tape 13, and the like can be determined as appropriate. Similarly, the suction tape 13 can be provided on the mounting surfaces 10a and 20a in the second embodiment.

<Optical film packaging>
FIG. 5 shows an example in which a plurality of optical films P are laminated and then wrapped with a thin film 14 such as vinyl. When the optical film P is stored in the plate-shaped article storage case 1 shown in FIGS. 1 and 2, the optical film P can be stored in a state of packaging as shown in FIG. This packaging is also preferably vacuum packaging. A cutout 14a is provided at the center of the film 14, and when the internal optical film P is taken out, the cutout 14a may be torn and the packaging bag divided into two is pulled left and right. Thereby, the optical film P can be protected at the time of transfer.

<Rack structure>
Next, a first embodiment of a rack structure will be described with reference to FIG. In FIG. 6, a rack body 30 is provided with a large number of drawers 31 that can be opened and closed. Each drawer 31 can accommodate the plate-shaped article storage case 1 described with reference to FIGS. 1 and 2. The number of plate-shaped article storage cases 1 stored in the drawer 31 can be arbitrarily determined. As shown in FIG. 6B, the rack body 30 can be covered with a cover 32 to take a dustproof measure. The rack body 30 can be placed on a cart (not shown) or on a transport truck.

  FIG. 7 is a diagram showing a second embodiment of a rack structure. In FIG. 7, the rack body 40 is formed with a storage space 41 for storing the plate-shaped article storage case 1 shown in FIGS. 1 and 2. One or a plurality of plate-shaped article storage cases 1 can be stored in the storage space 41. A wheel 42 is provided at the bottom of the rack body 40 and can function as a returnable box. A door 43 for closing the accommodation space 41 is provided. The door 43 can employ a double door opening / closing method, a method of opening / closing with a chuck, or the like.

<Platform transfer cart>
Next, a configuration example of the plate-shaped article transfer carriage will be described with reference to FIG. In FIG. 8, the rack body 40 is attached in a state of being suspended from the carriage body 50. The rack body 40 can have the same structure as that shown in FIG. The cart body 50 includes a support frame 51 and wheels 52 on the bottom surface. A key-shaped suspension 53 is provided on the ceiling of the support frame 51, and the upper four corners of the rack body 40 are suspended by strings 54. Further, the lower four corners of the rack body 40 and the bottom of the support frame 51 are also connected by a string 55. About the strings 54 and 55, the thing of a suitable material can be used. Moreover, you may use things like a chain and a spring instead of a string. By suspending the rack body 40 by such a method, vibrations and impacts are hardly transmitted to the optical film P in the rack body 40 at the time of transfer, and damage can be prevented. Accordingly, the suspension 53 and the strings 54 and 55 function as a vibration absorbing mechanism.

  FIG. 9 shows another embodiment of the vibration absorbing mechanism, in which a cushion 56 is filled between the rack body 40 and the support frame 50. As the cushion 56, for example, polystyrene foam or the like can be used. In addition, it may be supported by an air spring.

<Configuration of optical display device manufacturing system>
FIG. 10 is a diagram for explaining the configuration of the optical display device manufacturing system of the present invention. In the following description, the strip-shaped sheet product will be described as a polarizing plate original.

  The conveying means (corresponding to the supply means) is configured to be able to install a roll 84 around which the polarizing plate original 83 is wound, and to draw the polarizing plate original 83 from the roll 84. The conveying unit is configured to include the conveying roller 91 and the like, but is not particularly limited as long as the function is realized.

  The peeling means (not shown) peels the release film (not shown) from the polarizing plate original 83 before or after the detection of the defect by the detecting means 92 described later. This is preferably performed before the defect detection by the detection means 92. The cleaning means cleans the polarizing plate original 83 from which the release film has been peeled off. A known technique can be applied to the peeling unit 94 and the cleaning unit 95.

  The detecting unit 92 detects a defect on one or both sides of the polarizing plate original 83 drawn from the roll 84. Examples of the “defect” include scratches, dirt, cracks, and the like. The detecting means 92 is composed of, for example, a plurality of CCD cameras, a certification device, etc. arranged in a line along the width direction of the polarizing plate original 83 (see JP-A-2005-62165, page 13).

  For example, a first camera row 92a and a second camera row 92b are arranged in order to detect a surface defect of the polarizing plate original 83. The first camera row 92a is provided with four CCD cameras along the width direction of the polarizing plate original 83, and the second camera row 92b is also provided with four CCD cameras along the width direction. ing. The second camera row 92b is arranged on the downstream side of the first camera row 92a, and has a two-row arrangement in order to reliably detect defects. The third camera row 92c and the fourth camera row 92d are similarly arranged for the back surface. Further, the fifth camera row 92e is arranged immediately before the cutting processing described later, and is configured to detect defects. Defects that occur during the conveyance process, or leakage of detection in the first to fourth camera rows, etc. It is preferable to be able to cope with the above.

  The images acquired by the first to fifth camera rows 92a to 92e are sent to an image processing unit (not shown), and defects on the surface or inside of the polarizing plate original 83 are imaged using an image processing technique. Perform detection. The image processing unit can be configured by software such as an image processing program. Of course, the image processing unit may be configured by hardware. The image processing unit determines whether or not it is a defect and obtains a defect position. As described above, the first to fifth camera rows 92 a to 92 e and the image processing unit function as the detection unit 92 that detects a defect of the polarizing plate original fabric 83. In addition, a known algorithm can be adopted as the defect determination algorithm when the image processing program is used.

  The cutting processing means 93 cuts the polarizing plate original fabric 83 into a predetermined size based on the detection result of the detecting means 92, and processes the original polarizing plate article (polarizing plate 83a). The “cutting” can be cut by a guillotine method or a punching method, for example. The original polarizing plate 83 is adsorbed at a negative pressure by the adsorbing means 94, conveyed by a predetermined size, and cut by the cutting processing means 93.

  In this cutting process, cutting is performed with a predetermined size, but the size may be stored in a memory in advance, or the size value can be appropriately input or selected by the operator of the apparatus.

  The cutting process when a defect is detected will be described below. The original polarizing plate 83 after the defect detection process is sequentially conveyed by the supply means such as the conveyance roller 91 and the suction means 94. When the cutting means 93 cuts the polarizing plate original 83 including the defective portion, for example, when the defect exists at a position 20 cm long from the immediately preceding cut end surface, the polarizing plate original 83 is cut into a cross section. It is conveyed and cut so as to be cut at a position 21 cm long. The polarizing plate 83a cut in this way is determined as a defective product, and is conveyed and removed along a defective product conveying means (not shown). If the predetermined size is 50 cm long from the cut cross section, the yield of the polarizing plate 83a can be greatly improved by cutting in this way. The said conveyance means is implement | achieved by the belt conveyor, for example, and can convey inferior goods.

  In addition, when employ | adopting the punching method as the cutting process means 93, the polarizing plate 83a of various magnitude | sizes can be punched by changing a punching die. That is, polarizing plates 83a of various sizes can be obtained from the same polarizing plate original 83.

  When there is no defect, the polarizing plate 83a cut to a predetermined size is transferred to the laminating process step while being stacked on the cassette 10. For example, the cassette 10 is mounted on a transfer truck and transferred. Although FIG. 10 shows the cassette 10 shown in FIG. 1, other cassettes and carts may be used.

  In the bonding process, as shown in FIG. 11, a liquid crystal cell substrate 85 (optical display unit) is set in advance, and a polarizing plate 83a is placed on the liquid crystal cell substrate 85. At this time, the roller member (corresponding to the bonding processing means) is put on the liquid crystal cell substrate 85 and bonded so as to press the polarizing plate 83a while rolling. Thereby, mixing of bubbles can be suppressed, and a defoaming process step described later can be deleted or performed in a short time. In addition, it is not limited to the bonding method by a roller member, You may perform the bonding process by another method.

  Next, the adsorbing means 99 transfers the liquid crystal display device (corresponding to an optical display device) in which the polarizing plate 83a is bonded to the liquid crystal cell substrate 85 to the next step. The adsorbing means 99 has the same function as the adsorbing means 94 described above.

  Next, the second detection means 98 detects a defect on the transferred liquid crystal display device. As a detection method, the same means as the detection means 92 can be used. When a defect is detected, rework processing is performed. If no defect is detected, a defoaming process is performed. And it can also be comprised so that it may be reversed so that the polarizing plate 83a can be bonded together also about the other surface where the polarizing plate 83a is not bonded together, and it returns to the bonding process. The defoaming process may be performed before the defect detection by the second detection means 98.

<Flowchart of manufacturing method>
Below, the manufacturing method of the optical display apparatus of this invention is demonstrated using the flowchart of FIG.

  First, a belt-like sheet product (for example, a polarizing plate original fabric) is set in a manufacturing system (S1). The belt-like sheet-like product is sent from the optical film manufacturer in a roll form, and the assembly processing manufacturer disassembles the package, cleans the roll surface, and sets it in the manufacturing system.

  Next, the release film is peeled off (S2), and the strip-like sheet product after peeling is washed (S3). Washing is preferably performed using a pressure-sensitive adhesive.

  Next, a defect detection process is performed (S4), and based on the inspection result, a non-defective product is cut into a predetermined size or a defective product including a defective portion is cut (S5). If the cut product is a defective product having a defective portion (S6), it is removed as a defective product (S7). If it is a non-defective product (S6), it is transferred by the cassette 10 or the like (S8), and a bonding process is performed (S9). The detection process may be performed in several stages.

  Next, a defect as an optical display device is detected (S10). If it is determined as a defective product from the detection result (S11), a rework process is performed (S12). If it is determined that the product is non-defective (S11), the process proceeds to the next processing step (S13). A defoaming process is illustrated as a next process. Moreover, the process comprised so that it can invert so that a sheet-like product can be bonded also to the other surface where the sheet-like product is not bonded, and can transfer to a bonding process is illustrated.
