Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a barrel grinding method. [Prior Art] Conventionally, in the barrel polishing of the calender, there has been a barrel polishing apparatus which can grind the work roll in a state of being incorporated in the roll chock (for example, refer to Patent Document 1). Further, there has been an in-line drum dresser which can be ground into a work roll of a calender and a support roll (for example, refer to Patent Document 2). These devices are used to prevent the production efficiency from degrading due to the replacement of the drum or the transport of the drum to the repair shop, and the drum is ground in a state where the drum has been incorporated into the calender. Further, there is a barrel polishing method for injecting a temperature-controlled abrasive in a manner of re-polishing a calender roll taken out from a calender in a shorter time so as to extend the entire length of the surface of the body portion of the calender roll, thereby causing calendering The roller is held at a temperature relatively close to that of the rolling operation, and the grinding stone is brought into contact with the surface of the body portion of the calender roll to be ground. (For example, refer to Patent Document 3). In addition, there is a polishing apparatus which changes the contact surface stress distribution by adjusting the temperature of the contact surface between the polishing head and the workpiece to suppress the difference in smoothness, flatness, and parallelism of the workpiece, and has a grinding effect. A heating device that supplies a heating fluid to the head for heating (for example, refer to Patent Document 4). Further, there is a polishing drum provided with a plurality of pores for adsorbing the abrasive paper on the surface and a passage for cooling water (see, for example, Patent Document 5). [Patent Document 1] Japanese Patent Laid-Open No. Hei 5-237521 (Patent Document 3) JP-A-58-4343 (P. 4) [Patent Document 4] JP-A-2002-83791 [Patent Document 5] JP-A-2002-355765 [Summary of the Invention] [Problems to be Solved by the Invention] The 6 series shows a view of the slot nozzle 对 for the web coating fluid traveling on the back roll. The rear roller 101 is rotated in the direction indicated by the arrow A. The net 1〇3 is wound around the rear roll 101 and conveyed in the direction indicated by the arrow B. The slot nozzle 1〇5 is disposed with a small gap G between the rear roller and the rear roller ι〇. The fluid ejected from the slot nozzles 5 is applied to the mesh 103. (Influence of geometric shape) In order to apply a fluid to the mesh 103 with a uniform thickness, the gap G between the slot nozzle 1〇5 and the rear roller 101 is preferably kept constant in one rotation of the rear roller 101. If the roundness of the rear roller 101 is deteriorated, the gap G changes with the rotation of the rear roller 1 〇 1 in one rotation of the rear roller 101. If the gap G changes, the thickness of the fluid applied to the mesh 103 also changes. Therefore, in order to apply a fluid to the net 103 with a uniform thickness, it is preferable to increase the roundness of the rear roll 1〇1. In addition, the gap G should be uniform throughout the entire length of the slot nozzle 1〇5. If the cylinder of the rear roller 101 is inferior, the gap G changes in the longitudinal direction of the slot nozzle 1〇5. If the gap G changes, the thickness of the fluid applied to the mesh 1〇3 also changes. Therefore, in order to extend over the entire length of the slot nozzle 105, i.e., over the roll 145386.doc 201032949, it is preferable to increase the entire range of the cylinder length of the rear roller 101 so that the gap G is uniform. (Impact of installation error) No) and the bearing frame (not shown in other aspects, the rear parent 1〇1 is rotatably held by a bearing (not shown). The bearing has a tolerance. The inner wheel of the bearing is of good precision. The nominal inner diameter of the small diameter also has an allowable error of, for example, about 2.5 micrometers (μη1), and the outer diameter of the bearing is even a standard diameter of a small diameter with a good accuracy level, 'for example, about 4 to 5 micrometers ( (4) The allowable error. (4) There is also an allowable error of the tolerance of about 3 to 5 micrometers (_) on the bearing frame of the bearing. The inner and outer wheels defined by the claws 1514 are == degrees, except for the tapered roller bearings. When the inner diameter of the nominal bearing of the inner ring of the radial bearing is 18~30, the average inner diameter Ζ difference under the accuracy level of 2 is upper 0~low-2.5 μπι, and the accuracy grade is 5 when it is upper 〇~下_6 In addition, when the nominal bearing inner diameter is 80~120 mm, the average inner diameter size difference of the accuracy grade is 2 to 0~5, and the accuracy level is 5 to 0~ -10 μιη. When the outer diameter of the nominal bearing of the outer wheel is 5〇~8〇 claws, the accuracy level The average outer diameter difference of level 2 is upper 〇~low _4 μιη, and the accuracy level is 5 when the upper 0~low-9 μηι 'other' nominal bearing outer diameter is 150~180 mm, the accuracy grade is 2 The average outer diameter difference of the level is upper ~ lower ~ 7 μιη, and the upper level is lower than the lower level = 13 μπι. Therefore, when the rear roller 101 is mounted on the bearing frame by the bearing, due to the valley The error will cause the rotation of the rear roller 101 to vibrate. Even if the roundness and the cylinder of the rear roller 101 are increased, the rotation of the bearing and the bearing frame is 145386.doc 201032949, which will cause the subsequent rotation to occur. The vibration of the rear parent (8) changes the gap 后 between the rear roller 1〇1 and the slot nozzle 1〇5. Therefore, the gap 变得 becomes unfixed over the entire length of the drum surface of the rear roller 101, resulting in coating. The thickness of the fluid on the mesh 103 changes.

Even if the roundness and the cylinder are good at room temperature, the pro-101 will cause the back roll 101 to be distorted due to the temperature rise. If the drum is polished at room temperature, it is sometimes heated to a specific use temperature. Will produce a difference in roundness. For example, if the temperature rises by 6 generations, the roundness will produce an error of up to ±30 μm. In particular, in the case where the structure of the rear roller 101 is complicated, the deformation of the roller 101 becomes large after the temperature rises. If the structure of the rear roller is simple, the influence of temperature is small, but when the structure of the rear roller is complicated, the temperature influence is large. (Impact caused by pressure) η is placed on the rear roller 1 〇 1 to circulate the heating medium or the cooling medium to adjust the temperature. For example, the heat medium is supplied to the passage of the rear roller at a pressure of about 0.1 to 0-7. Once the passage is pressurized by the heat medium, the rear roll ι〇ι will expand and deform. Therefore, it is an object of the present invention to provide a drum grinding method for obtaining a drum having a good roundness.

The outer peripheral surface of the second roller (3) can be heated by the heating mechanism (25) or cooled by the cooling mechanism (25). Thereby, the outer circumference of the second roller (3) can be made ( The temperature of 3c) is adjusted to be the same as the actual use temperature of the first drum (17), or lower than the temperature of 2 〇 < t. The first drum (17) and/or the second drum (3) The inside can be heated by heating means (25, 27) circulating the heat medium inside the first drum (17) and/or the second drum, or by cooling means (25, 2). The temperature of the heat medium can be adjusted to adjust the temperature of the first roller (17) and/or the second roller (3) of the 145386.doc -9. 201032949. The inside of the first roller (17) can be layered ( a plurality of fluid flow paths (37, 38, 39J) of 35a, 35b, 35c). by applying a heat medium pressure (for example, M2 Mpa) when using a heat medium to the first roller (17), it is possible to perform grinding. The influence of the deformation due to the pressure is reduced. Further, by applying the vacuum pressure for the adsorption net to the first roller (17), the grinding can be performed. The influence of the force and deformation is reduced. The temperature difference between the first roller (17) and the second roller (3) may be within 2 〇t. 0 The face length (L1) of the first roller (17) may be the second The surface length (L2) of the drum (3) is 1/2 or less. The grinding mechanism may be a grinding belt (29) provided by winding the second drum (3) into a spiral. The method comprises the steps of: grinding the outer peripheral surface (17c) of the first roller (17) with a grinding belt of coarse abrasive grains, and then finishing the outer circumference of the first roller (17) with a grinding belt of fine abrasive grains. Step of the surface (17c). The fifth step may include: grinding the outer peripheral surface (17c) of the first roller (17) until the vibration of the first roller (17) is within 5 μηι.

For example, it is also possible to initially grind a grinding belt having a coarse particle size (abrasive grain) of 320 mesh or less with a count of (4), and then perform finishing with a fine-grained abrasive tape of 400 mesh or more. In addition, it is better to 145386.doc -13- 201032949, initially grinding with a coarse-grained abrasive belt of 320 mesh or less, followed by intermediate grinding with a fine-grained abrasive belt of 400 to 600 mesh, and then 1000 Finishing of finer-grained abrasive belts with a mesh size of 1 or more. This is a step-by-step use of abrasive belts from coarse abrasive to fine abrasive to repair surface mussel injuries. The polished surface can be quickly ground by shortening the overall grinding time. Furthermore, the value of the count (mesh) originally represents the number of meshes per square inch (2 5.4 mm), which is the unit of the particle size of the abrasive particles (abrasive material). Less, the finer the abrasive, the larger the value. As the type of the polishing tape, for example, a Mirror Film (trade name) series manufactured by Sankyo Co., Ltd., or the like can be used. In the present embodiment, the outer peripheral surface 丨 7e of the drum 17 is ground by the grinding drum 3 until the vibration of the drum (first drum) 17 to be ground reaches within 5 μm. Here, the roundness of the drum is centered on the drum and used as a reference. On the other hand, the vibration of the drum refers to the surface of the drum when the drum is assembled into the bearing group stereo 24 and rotated by the bearing 19. Vibration. Furthermore, it is also possible to heat or cool the drum to be ground (the first roller opening 7 to adjust the temperature of the outer peripheral surface 17c of the drum (first drum) 17 to be ground to the actual use temperature. The heat medium supply pipe 27 can be supplied. The heating medium is supplied to the inside of the drum 17 to heat the drum (first drum) 17 to be ground. Alternatively, the cooling medium can be supplied from the heat medium supply pipe 27 to the inside of the drum 17 to cool the drum 17. Thereby, the drum to be ground is ground ( When the first roller 17 is 17, the temperature of the outer peripheral surface 17c of the drum opening can be adjusted to the temperature which can be actually used. By grinding the drum 17 at the actual use temperature, the influence of the temperature on the polishing accuracy of the drum 17 can be reduced. Further, 145386.doc • 14- 201032949 Alternatively, the grinding drum (second drum) 3 may be heated or cooled, and the temperature of the outer peripheral surface of the drum portion 3a of the drum 3 may be adjusted. The heat medium supply pipe may be supplied to the inside of the drum 3. The polishing drum (the second drum) is heated by heating the medium. Alternatively, the cooling medium can be supplied from the heat medium supply pipe 25 to the inside of the drum 3 to cool the drum 3. Thereby, the drum to be ground is ground. When a roller is 17, the temperature of the outer peripheral surface of the drum 3 can be adjusted. During the grinding, the temperature of the grinding drum can be adjusted to be the same as the temperature of the drum 17 to be ground. The temperature of the grinding drum 3 can also be polished. The difference in the actual use temperature of the drum 17 is the same as or lower than about 20 C. That is, the temperature difference between the grinding drum 3 and the drum 17 to be ground can be in the range of 〜 -20. (: within the range of grinding. Figure 5 A partial cross-sectional view of the drum portion of the drum (first drum) to be ground. The inside of the drum portion 17a of the drum (first drum) 17 to be ground is formed into a plurality of fluid flow paths in a layered manner. The drum portion 17 & The inner layer 35a is formed in a spiral shape by a heat medium flow path 37 through a heat medium, and a heating medium or a cooling medium is supplied to the heat medium flow path 37 to adjust the temperature of the drum (first drum) 17 to be polished. The heat medium is supplied at a pressure of about oj^jMPa. If the heat medium applies pressure to the drum 17, the drum expands and deforms. In order to reduce the influence of pressure on the grinding precision, the pressure of the drum 17 is used (for example, 0.2 MPa) is applied to the fluid flow path to grind the drum 17. The intermediate layer 35b of the drum portion 17a forms a suction passage 38 for supplying vacuum pressure. A vacuum pressure of about -90 kPa is supplied to the suction passage 38. The outer layer is outside the drum portion 17a. 35c is provided with a plurality of suction holes 39. The suction holes 39 communicate with the suction passages 38, whereby the net conveyed on the drum 17 is adsorbed to the drum 145386.doc.15-201032949. In this embodiment, The circle t of the roller (first roller) 17 to be grounded may be lower than ', and the roller is not vibrated', so that no particular attention is paid to the degree of cylinder. The first roller that is ground according to the embodiment is used as a slot nozzle after the roller When used, the fluid is applied to the web at a uniform film thickness. In the case where the fluid is used as a hot-melt material, the hot-melt material can be applied to the web at a stable film thickness of 1 μm or less. (Production of the polishing drum 3) In the production of the polishing drum 3, if the diameter of the polishing drum 3 is small, a drum having excellent roundness and cylindricality can be produced by a prior grinding method. However, in the previous method, it is difficult to produce a drum having a large diameter with excellent precision. However, it is sometimes necessary to use a grinding drum 3 having a large diameter. In order to make a grinding drum with a large diameter, firstly, a raw roller having a small diameter of a small roundness is produced. Then, the original drum was used as a grinding drum, and the drum having a large diameter was ground by the grinding method of the present invention. The diameter of the original roller can be 5 〇 mm~2 〇〇 melon. The smaller the diameter of the original roller, the easier it is to control the accuracy of the roundness of the original roller. The original cylinder can be of a simple construction because it is not susceptible to thermal deformation. The original roller can also expand. The original drum may be provided with a through hole along the rotation axis, and is heated by flowing oil into the through hole. The drum having a large diameter to be ground is rotated at a rotation speed of one revolution per minute, and the original drum is rotated at a rotation speed of several hundred rotations per minute. Right, the original roller should be rotated at about 2 rpm, and the diameter of the original roller 145386.doc -16 - 201032949 should not be too small. Grinding method A large diameter drum can be used as the original drum, and the larger diameter drum can be polished by the present invention to produce a straight rear large drum. Thus, the grinding drum 3 having a large diameter can be produced. (Modifications) However, the present invention is not limited to the above. The embodiments of the present invention have been described above with reference to the above embodiments.

It is difficult to increase the roundness of a conventional grinding drum. This is the opposite of the polishing drum 3 of the present embodiment in which the polishing tape is wound around the drum. The drum can be made with excellent precision. Further, since the difference in the thickness of the polishing tape is mainly caused by the difference in height of the abrasive grains flying out from the anchor material of the polishing tape, the difference in the thickness of the polishing tape is in the range of about ± 1 μm. When the polishing tape is wound into a spiral shape, the convex portion on the surface of the polishing tape is pressed downward to make the surface of the polishing tape flatter. Therefore, the grinding drum of the present embodiment can improve the roundness as compared with the conventional grinding drum. The abrasive tape can be attached to the drum by an adhesive tape or a strip. The present invention is not limited to the polishing tape, and may be a coating of a polishing material on a drum. The abrasive material need not be spiral. Hot air can be used for heating the drum. When the heat medium is hot air, in order to prevent the bearing portion from being heated, the drum may be surrounded to form a hot air passage so that the hot air is not blown to the bearing portion. In this embodiment, a suction hole for adsorbing the net is provided on the drum. However, the roll 145386.doc • 17- 201032949 can also have a configuration for jetting air. The present invention is not limited to the above embodiments, and may be embodied in other various forms without departing from the characteristics thereof.
