High-purity sheet processing equipment

The present invention relates to a sheet processing apparatus which has a function of preventing the cut piece from scattering or adhering to the surface of the sheet or cutting the foreign matter from the cut environment to the surface of the sheet when cutting the sheet which is required to have high cleanliness.

There are many types of electronic machines that use thin sheets that require high cleanliness. The method for producing such a thin plate material is a melting method, and for example, a plate having a thickness of 1 mm or less is produced by this method. As shown in Fig. 6, the sheet material is cut into a sheet material 100 having a predetermined length, and then conveyed in the conveying direction W, and the end portion 101 in the width direction is cut at a cutting line L to become a sheet having a specific width. 102. In the documents of the present specification and the patent application, the direction in which the sheet material is conveyed is referred to as "long direction", and the direction perpendicular to the conveyance direction is "width direction". In the case of cutting the sheet material, for example, it is cut along the cutting line L using a mechanical cutter or a laser. The cut piece 100 is scattered when the cut piece 100 is cut. If the cut piece is kept in a state of being scattered and adhered to the surface of the sheet, the quality of the processed sheet product is lowered. In addition, there is a case where the surface of the cut sheet adheres to the surrounding dust to lower the quality of the sheet. Therefore, as a prior art in this field, there has been a device for ejecting air from the front side of the cutter traveling direction to the center of the cutter rotation center, the cutter and the plate contact. In addition, as another prior art, there is a device in which a clean booth is provided in an injection molding portion of a plastic injection molding machine, and the cleaned air or the like is collectively blown to the injection molding portion (see, for example, Patent Document 2). In addition, as another prior art, there is a local air conditioning system in which clean air is blown down to a constant temperature region requiring high cleanliness and high-precision temperature management, and the constant temperature region is installed in a clean room (for example, refer to Patent Document 3) . [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-82413 (Patent Document 2) JP-A-60-245522 (Patent Document 3) JP-A-2000-18663 [Problems to be Solved by the Invention] However, in the case of Patent Document 1, the blade is cut by a cutter, and the cut piece or the like is blown away. However, the surface of the plate is adhered to the surface of the plate, and the plate cannot be cut. The resulting cut piece does not adhere to the surface of the sheet which becomes the product. Therefore, the quality of the sheet to be a product is still lowered. Further, in the case of the above Patent Document 2, it is possible to provide a clean booth in the injection molding portion to keep the injection molding portion clean. However, in an environment in which the cutting sheet is scattered, the cut sheet cannot be made. Attached to the surface of the sheet that becomes the product. Therefore, even with this technique, the quality of the sheet material to be a product is lowered. Further, in the case of the above-mentioned Patent Document 3, the room in which the inventive device is installed is set as a clean room, and the clean air is partially blown downward, and large-scale attraction is required in order to clean and clean a large-scale clean room. Devices and the like, and also devices for partially blowing clean air down, require a large initial cost and maintenance cost, and require a large equipment area. Accordingly, an object of the present invention is to provide a sheet processing apparatus which has a clean booth on a cutting machine for cutting a sheet material, and can prevent the cut sheet from scattering or flowing into the surface of the sheet material to be a product, and can maintain the sheet material at a high quality.

The "cutting" mentioned in this manual and the scope of the patent application includes the "cutting" and "breaking" of the sheet at a specific position. With this configuration, the clean shed can ensure a specific range of the sheet cut in the cutting machine in a clean environment. Moreover, the limited scope of the clean shed can significantly reduce the initial cost and maintenance costs required for the clean shed. In addition, the cut piece produced when the sheet material is cut is sucked to the outside of the cut portion in the width direction, and the dust collecting portion is used to collect the dust, and the cut piece is blown to the dust collecting portion by the blowing portion, so that it can be prevented. The cut piece or the like flows in and scatters to the surface of the sheet which becomes the product, and the surface of the sheet is maintained at a high quality. Further, the clean booth may be configured to cover a sheet material that is closer to the inner side in the width direction than the cut portion of the sheet material produced by the cutter, and the blow portion may be disposed to be formed by the cut portion of the sheet material. The cut piece is blown outward from the inner side in the width direction of the cut portion. With this configuration, the end portion in the wide direction is cut by the cutter, and the portion of the sheet which is the product is covered with the clean booth, and the cut piece produced by the cut portion is blown from the wide side to the outer side by the blow portion and is collected. Since dust is collected by the dust portion, it is possible to further prevent the cut piece or the like from flowing into and scattering to the surface of the sheet material to be the product, and to maintain the surface of the sheet at a high degree of cleanliness. Further, the clean booth may be configured to cover the entire cutting device with a cover covering the sheet cutting device, and the blow portion may be disposed such that the cut piece produced by the cut portion of the plate is cut from the cut portion The inside of the width direction is blown to the outside. According to this configuration, the entire sheet cutting device is disposed inside the clean booth that covers the covering material, and the cut piece produced by the cut portion is blown from the inside to the outside by the blow portion and is carried by the dust collecting portion. Since the dust is collected, it is possible to further prevent the cut piece or the like from flowing into and scattering to the surface of the sheet which becomes the product, and to maintain the surface of the sheet at a high degree of cleanliness. Further, the dust collecting portion may be partially disposed along the cut portion of the sheet material so as to be dust-collected by the cut piece that is blown outward from the cut portion in the width direction. According to this configuration, the dust collecting portion that is blown by the blowing portion from the inner side in the width direction of the sheet to the outer cutting piece can be used as a partial structure to save equipment costs. In addition, the above-mentioned clean booth can also set the internal gas pressure higher than the outside. According to this configuration, even if the gas pressure inside the clean booth is used, the cut piece produced at the time of cutting is more likely to be collected by the dust collecting portion, and the cut piece of dust or the like can be prevented from flowing into the surface of the sheet more stably, so that dust or the like does not occur. Flowing in from the outside. According to the present invention, it is possible to prevent the cut piece or the like from scattering and flowing into the surface of the sheet material to be a product, and to maintain the surface of the sheet material at a high degree of cleanliness.
