Description

200523092 (1) 发明 Description of the invention [Technical field to which the invention belongs] The present invention relates to a roll device for forming a thin sheet or film (hereinafter referred to as "film"), and more particularly to a roll device The roll forming apparatus used in the technical field of a film-forming cooling roll device is a roll device. [Prior art] Φ Roll forming device for film forming, such as a cooling-type rolling mill device for forming a film by extrusion, sets the gap between adjacent forming rolls (hereinafter referred to as "roll gap") to be wider The relative position (hereinafter referred to as the “open position”) allows the resin to pass through the rolls, and then at least one of the rolls is opened and closed in opposite directions (hereinafter referred to as the “open and close of the rolls”), thereby resetting the relative position where the roll gap is narrow. Position (hereinafter referred to as "closed position"), and the film is formed by rotating the roll around its axis (hereinafter referred to as "rotation of the roll"). · The above-mentioned milky light opening and closing and roll rotation require driving force in different action directions. It is best to take this into consideration. Regarding the opening and closing of the milk roll, there are, for example, a rotation method in which the roll is opened and closed like a scissors around a suitable fulcrum; and a parallel method in which the roll is opened and closed by approaching or leaving the roll in parallel. The parallel method is preferably a shaft that supports the target roll at both ends. The -4-200523092 (2) method (hereinafter referred to as "the bearing Going forward "). For this reason, the roll forming apparatus for film forming includes a drive unit for advancing the bearings in parallel, and the following problems arise. Problem (A): The stopping position of the parallel bearing must be adjusted to properly maintain the parallelism between the rolls. (A 1) That is, it is necessary to give the rolls a parallelism that can achieve the required molding accuracy of the film. In this regard, the parallel drive unit is generally configured by operatively connecting a driving element composed of a hydraulic or pneumatic cylinder or an electric micro-screw to each bearing housing. Therefore, as long as the control time between these driving elements is adjusted, Even if it is not forced to stop due to mechanical impact, the position alignment between the bearings can be performed, so the required parallelism of the roll can be given. (A 2) In addition, the precision of the film required in the future will be more It is better to adjust the control time to adjust the position of the bearing even if it is affected by the subtle difference between the stopping positions of the bearings that move forward. Furthermore, since the roll device for film formation includes a rotation driving unit for rotating the roll, the following problems occur. Problem (B) • The torque of the rotary drive unit must be smoothly transmitted to the open and close rolls. The rotary drive unit usually includes an electric motor and a speed reducer connected to the motor. Therefore, it is necessary to transmit the torque of the reducer output shaft to the opening and closing rollers without using leverage. & point 'As long as a rotary drive unit is provided on each roll, and the frame of the reducer 200523092 (3) is fixedly combined with a holding frame for holding a bearing on one side of the roll, and then with the roll and the other The side bearings are mounted on a common movable frame to keep them parallel, and by integrating all of them, the output shaft of the reducer can be directly connected to the opening and closing rollers, and the torque can be smoothly transmitted without `` leverage ''. The position of the bearing can be accurately aligned, and the aforementioned problem point (A) including the future problem (A2) can be solved. However, the following problems arise. Problem (C): Since the combination of the rotary drive unit and the bearing is fixed, (C 1) the vibration during the operation of the motor and the reducer is directly transmitted to the bearing, which is not good for film forming. (C2) In addition, each time the rolls are replaced, the motor and the reducer's frame must be separated and recombined with the bearing's holding frame, and the parallelism must be adjusted again, making the operation time-consuming. In this regard, the conventional thin film forming roll device exemplified in the following Non-Patent Document 1 fixes a motor and a reducer of a rotary drive unit to a bottom frame thereof, and forms the reducer into a worm-driven compound shaft shape and The output shaft and the opening and closing rolls are connected by an eccentric torque transmission element. The reducer is driven by a single motor with 7 belts. [Non-Patent Document 1] Toshiba Machinery Co., Ltd.

H 1 m > 200523092 (4) The structure of this conventional film forming roll device is shown in a plan view in the first place. Illustration. The roll device shown in FIG. 1 includes: a] bottom frame Fr] fixed to the base of the factory and having a substantially C-shaped plane; left and right bearings 1 1 2, 1 1 3 fixed to the front of the first bottom frame Fr 1. ; Fixed cooling rolls 1 1 which are shaft-mounted on these bearings Η 2, 1 1 3; movable cooling rolls 2 1 which can be opened and closed with respect to this roll 11 1; and two of these shafts' 2 1 The left and right bearings 1 2 4 and】. 2 5 also have the bearing housings of these bearings 1 2 4 and 1 2 5 go forward and backward with respect to the rear part of the i-th bottom frame F r 1 respectively (D 1, D 2) And a rotation driving unit Dr2 that rotates each of the milk rollers 1 i and 21. This rotation driving part Dr2 includes a second bottom frame Fi * 2 fixed to the above-mentioned ground and integrated with the front part of the first bottom frame Fr 1 and having a substantially T-shaped plane; a single piece fixed to this bottom frame Fr2 Electric motor 丨 i 7; Transmission mechanism B t fixed to the bottom frame Fr2 and preventing transmission of vibration by using belts and pulleys is connected to the worm-wheel-type compound shaft reducer R d of the motor 1 1 7; this reducer The output shaft on the front side of R d] transmits the torque of 1 8 to the fixed rolling light]] directly coupled joint; 1 4; and transmits the torque of the output shaft 1 3 0 on the rear side of the reducer r J to the movable roller 2 1 moment transmission factor 1 26. The structure of this torque transmission element I 26 is shown in a plan view in Figure 2. The torque transmission element] 2 6 is through the front and rear links] 2 6 e, 1 2 6 f group (two in each group) 'will be directly detected using fei inspection Combined with the output shaft of the reducer Rd 200523092 (5) shown in Figure 1] 3 0 input disk at the flange portion] 2 6 a (front side of Figure 2), directly coupled to the movable roller with bolts 2 1 The output disk 126b (rear side in FIG. 2) of the flange portion of the input shaft and the intermediate disk 1 2 6c interposed therebetween are connected using these links 2 6 e,] 2 6 The eccentric constant velocity type joint with f crankshaft moving to transmit torque is called Schmitt coupling. Even if the rotating shaft center is shifted radially between the input and output disks 1 2 6 a and 1 2 6 b, This deviation is absorbed to a maximum of about 100 mm. In this way, the deviation of the rotating shaft center caused by the opening and closing of the movable roller 21 with respect to the output shaft 1 3 0 of the reducer Rd can be absorbed, even if the frame of the reducer Rd is not directly coupled to the bearing i 2 4, 1 2 5 bearing box, roller can also use bearings 1 24, 1 25 and then open and close, and can solve the conventional problem points (A 1), (B)-(C). Moreover, it can be installed even in places where the left and right widths of the bottom frames Fr 1 and Fr2 are restricted. Furthermore, when manufacturing a thin film for optics or the like that requires high-precision smoothness on the surface of a product, the rotation variation of the roll 2 can be made smaller than that of other conventional devices. Furthermore, the distance between the output shafts 1 1 8 and 1 3 0 of the speed reducer Rd can be made larger than the distance between the shafts of the front and rear rolls 1 1 and 21 in the closed position. [Summary of the Invention] [Problems to be Solved by the Invention] However, "the roll forming apparatus for thin film forming" having the advantages shown in the figure "has also caused new problems as the quality of the thin film becomes higher. 200523092 (6) Problem (D): Because the motor and reducer of the rotary drive unit are fixed on the bottom frame, (D)) As the roll is opened and closed, the rotation axis of the roll will be removed from the output shaft of the reducer. The axis of rotation is biased, and the torque needed to allow this bias is transmitted. (D 2) Since the Schmitt coupling is used as the torque transmission element, there may be horizontal lines in the film due to the fine rotation fluctuation caused by the movement of the connecting rod of this joint. # (D 3) In addition, if you want to make the Schmitt coupler with an eccentric joint more accurate than in the past, due to the subtle movement of the stop position of the parallel bearing and the coupling component that absorbs this difference 〃 "Leverage" relationship, the aforementioned future problem (A 2) may become a practical problem. (D 4) Furthermore, due to the amount of shaft deviation allowed by the Schmidt coupler, the opening and closing positions of the rolls are limited Furthermore, the number of movable rolls (for example, one on each side) on the outside of a pair of open and close rolls can be set side by side. Fl is also limited. This is because with the increase of the set rolls, the bearing travel distance also increases. Will increase, so that the amount of deviation between the roller and the output shaft of the corresponding reducer will increase. Problem (E): Since a single motor is used to drive the wheel-type double-shaft reducer with a belt, therefore, (E)) Due to the small rotation fluctuations caused by the action of the worm gear that drives several output shafts at the same time, there may be horizontal lines in the film. (E2) Moreover, due to the small rotation of the belt drive part using the pulley, the winter 20 0523092 (7) Variation 'may cause scum and shell lines in the film. (E 3) Furthermore, the surface accuracy of the film may be impaired due to the dust from the belt drive.

The present invention is to not repeat the aforementioned conventional problem points (A), (B), (C) and eliminate the above-mentioned new problem points (D) and (E), while solving the previously existing problems (A 2 ) And the creator. Therefore, an object of the present invention is to provide a thin film forming peripheral roll device that can be opened and closed by the incorporation of a bearing without accompanying the above problems (A) to (E). The object of the present invention is also to provide a film which can be manufactured with a simple structure, a small roll rotation variation, and a high degree of surfaceability (smoothness), and it is also desirable to provide a film forming process that is easy to perform with conservative operations including roll replacement. Roller device. [Means for Solving the Problems] In order to achieve the above-mentioned object, the roll forming device for thin film forming of the present invention includes: a roll for forming a thin film; a bearing for supporting the roll; a parallel drive section for opening and closing the bearing and the roll; And a rotary drive unit for rotating the roll, further comprising: -10- 200523092 (8) movable coupling means for linking the rotary drive unit to the bearing in a movable state; and making the rotary drive unit and the bearing move in parallel And a flexible torque transmission element for transmitting the torque of the rotary driving unit to the rolling II. According to the present invention, the rotation driving portion connected to the bearing in a movable state is moved in parallel with the bearing. That is, first of all, because there is a milk roller supported by a bearing and opened and closed by the lapse of the bearing, there is also a rotation driving part that rotates the roll. Therefore, the rotation driving part is connected to the bearing. In a movable state, this bearing advances. In addition, there is a flexible torque transmission element for transmitting the torque of the rotary driving unit to the roll. That is, in the roll forming device for thin film forming with the above configuration, (F) Since the rotary driving unit is connected to a movable state, (F)) The foregoing caused by the combination of the rotary driving unit and the roller in a fixed state can be eliminated. Problem points (D); (F2) At the same time, the aforementioned problem points (D) 〇 (G) caused by fixing the rotation driving part to the bottom frame can also be eliminated. Furthermore, since the rotation driving part and the bearing go forward, (G 1 ) It is not necessary to use a single motor to drive the worm gear type double-shaft reducer with a belt, but it can eliminate the aforementioned problems caused by this structure (E); (G 2) At this time, because the bearing is driven by itself and further Make the roller-11 _ 200523092 〇) open and close, so the previously known problem point (A 1) about the parallelism between the rollers can be eliminated, and because the light-weight core of the opening and closing is protruding from the design reference axis, it is driven by adjusting the rotation The control time for the advancement between the part and the bearing is such that the movable connection state can achieve a state where the core of the rotary driving part protrudes beyond the opening and closing rollers within the allowable vibration range of the rotary driving part. (Η) In addition, since there is a flexible torque transmitting element for transmitting the torque of the rotary driving unit to the roll, (Η 1) By turning the opening and closing roll through this torque transmitting element, the In the three-dimensional flexible range of the torque transmission element, the deviation of the core position between the rotation driving unit and the opening and closing rollers and the difference in the parallelism of the rotation axis are absorbed. Therefore, the vibration transmission range of the rotation driving unit is located in the torque transmission element. The flexible range can prevent the occurrence of "leverage", so the aforementioned problem point (B) can be eliminated; ((2)) Even if a subtle offset occurs between the parallel stop positions of the bearing, and due to this offset, An error is caused when the core of the open / close roll is exposed, and this error can also be absorbed by the flexible torque transmission element, so that the aforementioned problems (A2) can be eliminated. Therefore, according to the present invention, it is possible to provide a problem that does not accompany the aforementioned problems Point (A) to (E), and a roll forming device for film forming that can open and close the roll by bearing in parallel. It is preferable that the aforementioned torque transmission element has the same The flexible coupling to be connected. The advancement means preferably includes a first guide to guide the bearing, a second guide to guide the rotary drive unit, and a first and second 200523092 (10) guide. Means for maintaining parallelism It is preferable that the movable connection means includes: a first frame member that holds the bearing; a second frame member that supports the rotation driving unit; and a means for connecting the first and second frame members in a separable state. It is also preferable to have a means for sandwiching the rotation driving part on a fixed member.

Openable and closable cooling rollers 2 1 Driving device 2 7 Reducer (gearbox) 3 0 is fixed to a plate-shaped floating frame 3 2, and this floating frame 3 2 is a linear guide member 3 mounted on the bottom surface 2 a slidably engages on straight -23-200523092 (21) guide rail 3]. The electric motor 29 is mounted on the speed reducer 30 in a vertical arrangement with the positive father of the horizontal rotation axis of the cooling roll 2 丨. The bearing box 2 5 b is mounted on the bearing frame 2 5 c. The supporting frame 2 5 c is slidably engaged with the linear guide 23 by a linear guide member 2 5 d mounted on the lower bottom surface. In addition, the linear guide is also engaged in the bearing housing 2 4 b with the same structure. The floating frame 32 of the driving device 27 has an extension portion 32b extending to the bearing case 25b side. The extension portion 32b is detachably connected to the bearing frame 2 5c of the bearing housing 2 5 b by an engaging pin 3 2 c that can be engaged and disengaged at the front end. A clamp mechanism 3 3 is provided directly below the floating frame 32 of the driving device 27. The clamp mechanism 33 includes: a flanged clamp member 3 3 b driven by a fluid pressure cylinder 3 3 a mounted on the bottom surface of the frame 40; and fixedly mounted on the bottom surface of the floating frame 32, and The locking member 3 3 c is engaged with the clamp member 3 3 b. In addition, since the clamp member 3 3 b is a penetrating locking member 3 3 c, the through hole 3 3 d is an elongated hole facing the roll radial direction (direction of the guide rail). Thereby, the clamp member with a flange is attached 3 3 b As the fluid pressure cylinder 3 3 a is lowered, the locking member 3 3 c will be pulled down, and the driving device 27 will be fixed to the bottom frame 4 at a proper position in the radial direction of the roll. The roll forming device RL 1 for film forming is to move the pressure cylinders 3 6 and 37 in a state where the clamp mechanism 33 is released (un clamped state), and move the bearing housings 24 b and 25 b toward the roll in the radial direction to perform the rolling. Opening and closing. The radial movement of the rollers of the bearing boxes 24b and 25b is guided in parallel by the linear guides 22 and 23. -24-200523092 (22) When the roller is opened and closed, as the rollers of the bearing boxes 24b and 25b move radially, the drive device 27 will be guided by the linear guide 31 to move radially toward the roller. As a result, as the roll is opened and closed, the center axis of the roll and the center axis of the output shaft of the driving device 27 will not deviate, and the connection between the cooling roller 2 I and the output shaft 28 of the driving device 27 can be achieved by The direct coupling type flexible coupling 26 is performed without the need for a complicated universal joint like the Schmitt coupling. The roll forming apparatus for a film having the above configuration has the following effects. (ί) Since the motor is directly ‘τ; ρ σ’, the motor 29 and the reducer 30, there is no rotation variation. (2) Since there is no Schmitt coupling, the rotation variation in this part does not occur. (3) Since the reducer 30 uses helical bevel gears 3 o c and 3 o d, the rotation variation in this part is smaller than that of the worm gear type. (4) Since the flexible coupling 26 is used, even if the moving positions of the bearing boxes 2 4 b and 2 5 b on the left and right sides of the cooling roll 21 are slightly different and not parallel, the reduction gear 30 and the bearing will not be affected. damage. Although the absorption of the offset is as small as a few millimeters, it is adjusted except that the roll is moving so that the core of the cooling roll 21 is aligned with the core of the reducer 30, so there is no rotation variation. (5) Because of the existence of the clamp mechanism 33, the vibration of the speed reducer 30 is not affected when the film is formed. (6) Since the gap between the milk rollers can be increased in the open position of the cooling $ L light 21, the operation of passing through the sheet is easier and the safety is increased. -25- 200523092 (23) (7) The flexible coupling 26 can be removed and the roller 2 1 can be replaced without removing the reducer 30. (8) As long as the engaging bolt 3 2 c is pulled out, the bearing housing 2 5 b can be separated from the reducer 30. Therefore, the linear guides 23 and 31 can be used to individually and easily guide the movement of the bearing housing 25b and the reducer 30, and a conserved space can be secured. (9) Five or more cooling rolls may be provided in parallel. The chase point mode is to set the light weight to two, but it can also be set to three, or 13 or more.
