TECHNICAL FIELD OF THE INVENTION
The present invention relates to a defective portion removing apparatus and a defective portion removing method for manufacturing a recycled roll raw paper by removing a defective portion from a roll raw paper including a defective portion such as a scratch or a wrinkle.
[0002]
[Prior art]
FIG. 9 shows an example of a system configuration of a conventional defective part removing facility 180. This equipment unwinds a roll base paper 181 including a defective portion that has been wound up, including a defective portion such as a scratch or a wrinkle generated during a production process in a paper mill or a processing plant, and cuts the paper width according to the application. At the same time, the defective portion is removed, and only the high-quality portion is wound up to manufacture the recycled roll base paper 183. The configuration and operation thereof will be described below.
[0003]
In FIG. 9, a roll base paper 181 including a defective portion is transported from a storage location (not shown) by a crane or other appropriate known means, and is rotatably assembled to an unwinder 184. The web 185 is fed out while maintaining the tension.
Further, the web 185 is configured to be continuously cut by a slitter section 187 using guide blades 186a and 186b using a rotary blade or the like.
The web 185 cut to a predetermined width by the slitter section 187 is wound around a core 182 by a winder 188 via guide rolls 186c and 186d, and a recycled roll base paper 183 is manufactured.
[0004]
Although there are various types of winders 188, FIG. 9 shows a two-drum type, in which two sets of winder drums 196a and 196b rotatably supported by bearings 195 provided on a frame 198 are provided. ing. The winder drum 196 is configured to be rotationally driven by a motor (not shown).
The core 182 is mounted between the two sets of winder drums 196, and the web 185 is wound around the core 182 while being pressed by the pressing roll 189.
[0005]
The air cylinder 199 connected to the presser roll 189 adjusts the nip pressure between the winder drum 196 and the core 182 by appropriately adjusting the pressing force, and rotationally drives the winder drum 196 to generate frictional force. A web 185 is wound around a rotating core 182 to produce a recycled roll base paper 183.
[0006]
Further, if the tension of the web 185 fluctuates at the time of start-up, operation, and deceleration / stop, it causes troubles such as meandering, wrinkles and tears, so that the unwinder 184 generates an appropriate braking force to keep the tension constant. In addition, a device (not shown) for correcting meandering is provided in the middle of the equipment so that the web 185 can run normally.
[0007]
After winding the recycled roll base paper 183 to a predetermined length, the operation of the defective portion removing equipment 180 is stopped, the web 185 is cut in the width direction, and the paper ends are bonded with tape or the like. Next, the recycled roll base paper unloading lever 192 rotatably mounted on the axis of the winder drum 196a on the entry side is rotated in the direction of the arrow by extending the arm 193 connected to the lever 192 by extending the air cylinder 194. Then, the recycled roll base paper 183 is transferred to the roll base paper unloading stand 200 supported by the gantry 197. The recycled roll base paper 183 is carried out of the system by a known means (not shown).
[0008]
Next, a method of removing a defective portion will be described. The operation of the defective portion removing equipment 180 is stopped after confirming that the defective portion such as a scratch or a wrinkle unwound from the roll base paper 181 including the defective portion is once wound on the winder 188. The defective portion is known in advance, and is in a state where it can be identified by display means such as acquisition of defect information and marking in a previous process. The operator uses these data, and further operates and stops the defective portion removing equipment 180 while visually checking.
[0009]
Next, the defective portion 191 is removed as shown in FIG. That is, as shown in the figure, first, the operator 190 goes up to the roll base paper unloading stand 200 and cuts the defective portion 191 over the entire width of the recycled roll base paper 183 with a cutter or the like. Next, the end of the recycled roll base paper 183 is adhered and fixed with a tape or the like, and then the winder drum 196 is rotated to draw out and discharge the defective portion 191. Thereafter, the recycled roll base paper unloading lever 192 is operated in the direction of the arrow to transfer the recycled roll base paper 183 to the roll base paper unloading table 200. Further, when the winding is further continued after the defective portion is removed, the subsequent web 185 is pulled out together with the defective portion 191 by rotation of the winder drum 196, and after the defective portion 191 is discharged. In addition, the operator performs a connection operation of bonding the preceding web with a tape or the like.
[0010]
As described above, the conventional method of removing a defective portion from a roll base paper requires the operator 190 to enter the machine each time to perform the operation, which is a very dangerous operation, and requires heavy labor. It takes a long time and the work efficiency is poor.
Further, when the defective portion 191 is cut, the excess is cut to the normal paper so that the defective portion is not left on the recycled roll base paper 183, so that the product yield is deteriorated.
Further, since the re-adhesion work between the succeeding web after the cutting and removal of the defective portion 191 and the end of the recycled roll base paper is a manual work that requires accurate and uniform finishing, a skilled technique is required.
