A first coating blade portion 36 extending in the left-right direction and having a top surface in the form of a rectangular parallelepiped is formed at an upper end portion of the first main body 16.

  As shown in FIGS. 1 and 2, the second main body 18 is separate from the first main body 16, and is disposed behind the first main body 16, that is, above the base 20. It is a rectangular parallelepiped extending in the direction, and the vertical dimension is formed smaller than the first main body 16. A second inclined surface 26 is formed from the front upper end to the rear upper end of the second main body 18. A second coating blade portion 38 that extends in the left-right direction and has a flat rectangular parallelepiped upper surface is formed at an upper end portion of the second main body 18.

  A space 44 is formed between the second main body 18 and the base 20. The space 44 has an upper surface formed by the lower surface of the second main body 18, a lower portion formed by the upper surface of the base 20, a rear surface opened, a front surface formed by the rear surface of the first main body 16, and left and right side portions opened. It is a space that did.

  A plate-shaped shim 28 is sandwiched between the rear surface of the first main body 16 and the front surface of the second main body 18, as shown in FIGS. As shown in FIG. 10, the shim 28 includes left and right peripheral portions 30 and 32 and a lower peripheral portion 34 so as to surround the liquid reservoir 24.

  The first main body 16, the second main body 18, and the shim 28 are integrally fixed, and as shown in FIGS. 1 and 4, the first inclined surface 22 and the second inclined surface 26 are formed in a triangular shape. The upper end surface of the first coating blade portion 36 and the upper end surface of the second coating blade portion 38 are at the same height, and the lower peripheral surface of the backup roll 12 is positioned above it with a coating interval.

  Above the liquid reservoir 24, a liquid passage 40 is formed vertically between the first main body 16 and the second main body 18, and a slit-like discharge port 42 is formed at the upper end thereof. . That is, the slit-shaped discharge port 42 is located between the upper ends of the first coating blade 36 and the second coating blade 38. Both sides of the liquid passage 40 are closed by left and right peripheral portions 30 and 32 of the shim 28, and a lower portion is closed by a lower peripheral portion 34.

  As shown in FIGS. 2 and 3, a coating liquid supply port 46 penetrates through the center of the front surface of the liquid reservoir 24 provided in the first main body 16 in the left-right direction. A supply pipe 48 connected from a pump (not shown) for supplying a working liquid is connected.

  The bend device 8 is a substantially rectangular parallelepiped provided below the die 14, and a pair of left and right arms 52 is erected from both left and right sides of the upper surface. On the other hand, a pair of left and right support shafts 54 project from both side surfaces of the first main body 16, and are rotatably supported by a pair of left and right arm portions 52. Thus, the die 14 is rotatably disposed above the bend body 50 of the bend device 8 and is fixed at a specific position.

(2) Positional Relationship of Each Device The positional relationship between the backup roll 12 and the die 14 will be described. As shown in FIGS. 1 and 2, when the perpendicular S is lowered from the center O of the rotating shaft 13 of the backup roll 12, the perpendicular S is applied to the first coating blade 36 of the first main body 16 of the die 14. Pass through the front. Thereby, the upper surface of the first coating blade portion 36 is located at a position closest to the lower peripheral surface of the backup roll 12. As shown in FIG. 2, the coating liquid discharged from the discharge port 42 is coated on the surface of the web W by the backup roll 12 rotating counterclockwise. The gap between the first coating blade portion 36 and the web W running on the backup roll 12 is a coating gap.

  Next, the positional relationship between the ejection port 42 and the die pressing portion 58 will be described. The die pressing portion 58 is arranged on the lower surface of the base 20 such that the perpendicular S dropped from the center O of the rotating shaft 13 of the backup roll 12 passes through the center of the cylindrical die pressing portion 58.

(3) Operating State of Coating Apparatus 10 Next, an operating state of the coating apparatus 10 will be described with reference to FIGS. As shown in FIG. 1, the backup roll 12 is rotated in a counterclockwise direction, and the web W on the lower peripheral surface is caused to travel from the rear to the front (from upstream to downstream).

  The coating liquid is supplied from a pump (not shown) to the liquid reservoir 24 of the die 14 disposed below the backup roll 12 via a supply pipe 48 and a supply port 46. The coating liquid supplied to the liquid reservoir 24 rises from the liquid passage 40 and is discharged from the discharge port 42. The discharged coating liquid is applied to the surface of the web W running on the lower peripheral surface of the backup roll 12. The state at this time will be described in more detail.

  First, the first inclined surface 22 and the second inclined surface 26 of the die 14 are formed in a triangular shape, and upper ends thereof are a first coating blade portion 36 and a second coating blade portion 38. The first coating blade portion 36 and the second coating blade portion 38 have a so-called lip shape because the lips are in a state of protruding upward. Then, coating can be performed at the upper end of the lip mold. However, the problem here is that the lower peripheral surface of the backup roll 12 is an arc, and the upper surface of the first coating blade portion 36 and the upper surface of the second coating blade portion 38 have a planar shape. However, it is impossible to perform the coating with the same coating pressure and the same coating thickness on the entire upper surface of the first coating blade portion 36 and the upper surface of the second coating blade portion 38.

  For this reason, in the present embodiment, the front portion of the upper surface of the first coating blade 36 downstream of the second coating blade 38 is located directly below the center O of the rotating shaft 13. By doing so, the interval between the front portion of the upper surface of the first coating blade portion 36 and the lower peripheral surface of the backup roll 12 is the closest, and the coating pressure is applied most at this approached position. Therefore, coating is performed at the position where the coating pressure is the highest. That is, the interval between the front portion of the upper surface of the first coating blade portion 36 and the lower peripheral surface of the backup roll 12 is the coating interval, and the coating thickness is determined. Particularly, since the upper surface of the first coating blade portion 36 and the upper surface of the second coating blade portion 38 are set at the same height, the web W can run smoothly as shown in FIG. The distance between the rear part of the upper surface of the second coating blade part 38 and the lower peripheral surface of the backup roll 12 is A, the distance between the front part of the upper surface of the second coating blade part 38 and the lower peripheral surface is B, and the first coating is performed. Assuming that the distance between the rear portion of the upper surface of the blade portion 36 and the lower peripheral surface is C and the distance between the front portion of the upper surface of the first coating blade portion 36 and the lower peripheral surface is D, A> B> C> D, The coating pressure applied to the web W gradually increases, and coating can be performed at the position where D is the highest.

  On the other hand, due to the pressure of the coating liquid discharged from the discharge port 42, the upper end of the die 14 curves downward toward the center in the left-right direction. In order to prevent this bending, the lower surface of the base 20 of the die 14 is pressed by the die pressing portion 58 of the bend device 8. In the present embodiment, as shown in FIG. 2, the pressing position of the die pressing portion 58 is the center in the left-right direction, and the position directly below the center O of the rotating shaft 13 of the backup roll 12 in the front-rear direction. And The reason why the position just below the center O of the rotating shaft 13 of the backup roll 12 is pressed will be described. As described above, the interval between the front portion of the upper surface of the first coating blade portion 36 corresponding to the position directly below the center O of the rotating shaft 13 of the backup roll 12 and the lower peripheral surface of the backup roll 12 is the closest, The coating pressure is applied most at this close position. Therefore, in the front-rear direction, bending is most likely to occur at this portion. Therefore, in the present embodiment, a position immediately below the center O (the front portion of the upper surface of the first coating blade portion 36) of the rotating shaft 13 of the backup roll 12 is pressed in the front-rear direction to prevent bending.

  When the base 20 and the first main body 16 are bent, the second main body 18 fixed to the first main body 16 can be bent at the same time.

(5) Disassembling Method of Die 14 Next, a procedure of disassembling the die 14 and removing the second main body 18 will be described.

  In the initial state, as shown in FIG. 5, the first main body 16, the shim 28, and the second main body 18 are integrally fastened by eight fastening bolts 60.

  First, as shown in FIG. 7, the worker inserts and fixes a pair of left and right stud bolts 80 into the stud holes 88, 84, and 82.

  Next, as shown in FIG. 6, the worker inserts a pair of left and right push bolts 74 into the push holes 78 and 76.

  Next, the worker inserts the extension handle 102 into the handle 90.

  Next, the worker removes the eight fastening bolts 60 from the fastening holes 62, 64, and 66, as shown in FIG. At this time, since the nut 68 is pressed by the pressing plate 70 having the wing bolt 72, the nut 68 does not fall from the first main body 16.

  Next, the worker rotates the push bolt 74, presses the tip thereof against the rear surface of the first main body 16, and peels off the second main body 18 and the shim 28 from the first main body 16. Even in this state, as shown in FIG. 9, since the left and right stud bolts 80 are provided, the second main body 18 and the shim 28 do not fall, and the second main body 18 and the shim 28 Gradually moves away from the first main body 16 on the mounting surface 114.

  Next, the worker removes the pair of left and right stud bolts 80, holds the handle 98 of the pair of right and left handles 90 and the extension handle 102, and completely removes the first main body 16 from the second main body 18 by leverage. Remove. The second main body 18 is mounted on the mounting surfaces 114 of the pair of left and right mounting tables 106 such that the front surface of the second main body 18 faces upward. Since the pair of left and right mounting tables 106 has a structure for receiving the second main body 18 at the vessel point, the second main body 18 can be mounted in a well-balanced manner. Further, since the mounting surface 114 and the fence 112 are formed of synthetic resin, the surface of the second main body 18 is not damaged.

  Next, when the worker removes the second main body 18, the liquid reservoir 24 on the rear surface of the first main body 16 is exposed, so that the coating liquid attached to the liquid reservoir 24 is washed.

  Next, in order to assemble the die 14, the worker holds the handle 98 and the extension handle 102 by hand, stands the shim 28 and the second main body 18, and attaches the shim 28 and the second main body 18 to the first main body 16.

  Next, the worker puts the pair of left and right stud bolts 80 through the stud holes 88, 84, 82 again after standing the second main body 18.

  Next, the worker fastens the first body 16, the shim 28, and the second body 18 with the eight fastening bolts 60.

(6) Effect According to the present embodiment, the shim 28 and the second main body 18 are separated from the first main body 16 by the pair of left and right push bolts 74, so that the first main body 16 can be easily disassembled.

  Further, even if the fastening bolt 60 of the die 14 is removed, the second main body 18 and the shim 28 do not fall from the first main body 16 because of the stud bolt 80.

  Further, the second main body 18 and the shim 28 removed from the first main body 16 can be mounted on the mounting table 106, and therefore do not fall to the floor or the like.

  Since the mounting surface 114 and the fence 112 of the mounting table 106 are made of synthetic resin, the surface of the second main body 18 is not damaged.

  Further, since the pair of left and right mounting tables 106 are provided at the vessel point, the second main body 18 can be mounted with good balance.

  Further, since the handle 98 and the extension handle 102 are provided, the second main body 18 can be easily held, can be disassembled with these handles, and can be easily transported.

  Further, since the extension handle 102 is detachable, if it is unnecessary, it can be detached from the handle 90 and stored in another place, so that the space of the coating apparatus 10 has a margin.

  Further, since the nut 68 of the fastening bolt 60 is pressed by the holding plate 70, the nut 68 does not fall even if the fastening bolt 60 is removed. Further, since the nut 68 is used, the coating liquid leaked from the discharge port 42 of the die 14 does not enter. Further, when removing the nut 68, the nut 68 can be easily removed by removing the wing bolt 72. Then, if the nut 68 is removed, the rear surface of the first main body 16 in this portion can be cleaned.

  Since the pair of left and right mounting tables 106 are provided at the vessel point, when the second main body 18 is mounted, the central portion does not sag due to gravity and the sense of stability does not deteriorate.

Embodiment 2

  Next, the die 14 of the coating apparatus 10 according to the second embodiment will be described with reference to FIGS.

  After assembling the disassembled die 14 as in the first embodiment, it is necessary to adjust the height of the second main body 18 and the first main body 16. This is because the inner diameters of the fastening holes 62, 64, 66 are formed slightly larger than the diameter of the fastening bolt 60 with some margin, and in order to set the coating thickness finely, This is because the height of the second main body 18 needs to be finely adjusted. Therefore, in the present embodiment, a height adjusting device 200 for finely adjusting the height of the second main body 18 is provided. The height adjusting device 200 will be described with reference to FIGS.

(1) Structure of Height Adjusting Device 200 The height adjusting device 200 includes a positioning pin 204, an adjusting bolt 206, and a lowering bolt 208.

  As shown in FIGS. 12 and 13, a pair of left and right positioning pins 204 are provided at the vessel point on the lower surface of the second main body 18. An adjustment hole 202 penetrates the base 20 of the first main body 16 corresponding to the positioning pin 204 in the vertical direction. Then, the adjustment bolt 206 penetrates the adjustment hole 202 from the lower surface of the base 20 and is in contact with the lower surface of the positioning pin 204. The height of the adjustment bolt 206 is determined by adjusting the height of the positioning pin 204 on the lower surface of the second main body 18 to the upper end surface of the first coating blade 36 at the upper end of the die 14 with the positioning pin 204 riding on the tip of the adjustment bolt 206. It is preset so that the upper end surfaces of the two coating blades 38 coincide.

  Further, as shown in FIGS. 12 and 14, the lowering bolt 208 penetrates the base lowering hole 210 of the base 20 from the lower surface of the base 20 near each of the pair of right and left adjustment holes 202, and It is screwed into a second main body lowering hole 212 opened on the lower surface of 18. Accordingly, when the lowering bolt 208 is tightened, the lower surface of the second main body 18 is lowered, and the lower end of the positioning pin 204 rides on the upper end of the adjusting bolt 206.

  With the height adjusting device 200, when the second main body 18 attached to the first main body 16 is too low and hits the upper end of the adjusting bolt 206, the second main body 18 is moved upward, and Put on.

  Conversely, when the second main body 18 is too high and the positioning pin 204 is above the adjustment bolt 206, that is, in a floating state, it is necessary to lower the second main body 18.
