However, even in all of the above methods, it is difficult to apply the coating liquid so that the surface of the applied coating liquid becomes flat when applying the coating liquid to the concave curved surface. In addition, the R shape (curvature) of the concave curved surface varies depending on the curved base material, and there is no proper tray capable of holding various other curved base materials of the R shape.

(Total configuration)

1 is a schematic view of a coating apparatus 10 according to an embodiment of the present invention. 1, the coating apparatus 10 includes a reservoir tank 1 for storing a coating liquid, a slit nozzle 3 for applying the coating liquid to the curved base material 11 on the holding tray 2, A supply section 4 for supplying the coating liquid to the slit nozzle 3 from the storage tank 1 and a control section for controlling the coating apparatus 10. [ The slit nozzle 3 is a slit nozzle for a table coater for applying a coating liquid to a base material by forming a slit having a predetermined width for discharging the coating liquid to the nozzle itself and moving the slit nozzle 3. [

In the storage tank 1, high-pressure air is supplied, and by the pressure of the high-pressure air, the coating liquid is pushed downward. Further, the coating liquid in the storage tank 1 can be pushed by gravity without using high-pressure air.

The storage tank 1 is connected to the supply unit 4 through a two-way valve 12. The supply section 4 is provided with a syringe pump 44 and a three-way valve 48 which are driven by a motor 43. The storage tank 1 is connected to the first supply pipe 45 via the two-way valve 12 and the first supply pipe 45 is connected to the syringe pump 44 through the three- . The syringe pump 44 is connected to the second supply line 49 via a three-way valve 48. The second supply duct 49 is connected to the slit nozzle 3. The slit nozzle 3 is movable in the horizontal direction with respect to the holding tray 2. A coating film is formed on the curved base material 11 on the holding tray 2 by the coating liquid applied by the slit nozzle 3 . More specifically, the control unit controls the operation of the syringe pump 44 and the operation of the three-way valve 48, which are driven by the motor 43, in the storage tank 1 by controlling the supply unit 4, The supply pressure and / or the supply amount of the coating liquid to the slit nozzle 3 is controlled.

2 is a schematic perspective view of the vicinity of the slit nozzle 3 portion. 2, a slit, which is a discharge port of the coating liquid, is formed by a predetermined width in the nozzle moving direction (X direction) of the slit nozzle 3, and a slit (Y) direction. By moving the slit nozzle 3 in the X direction, the coating liquid is applied to the curved base member 11 on the holding tray 2 with a predetermined width. The control unit is capable of adjusting the moving speed of the slit nozzle 3 in the X direction. More specifically, the control unit controls the slit nozzle 3 so that the moving speed of the slit nozzle 3 in the X direction is inversely proportional to the distance D from the slit tip end 3a of the slit nozzle 3 to the surface 11a of the curved base 11, Thereby controlling the nozzle 3.

The curved base member 11 is curved so as to protrude downward so that the coated surface 11a of the surface has a concave curved surface when viewed in the Y direction, and furthermore, the concave curved surface has a constant curvature. The curved base member 11 has a configuration in which the concave curved surface extends in the Y direction.

Further, it is preferable that the coating liquid applied to the curved substrate 11 has thixotropy. Thixotropy is the property of intermediate substances in non-Newtonian liquids, such as gel-like fired solids and solations, which means that the viscosity changes over time. Concretely, when the shear stress is continuously applied, it means that the viscosity gradually decreases to become a liquid phase, and when it is stopped, the viscosity gradually increases to finally become a solid state. In the present embodiment, when the coating liquid is thixotropic, when the coating liquid is discharged from the slit nozzle 3, shear stress is applied and liquefied. When the coating liquid is applied to the curved substrate 11, And finally becomes a solid state. In other words, the coating liquid with thixotropic property usually has a high viscosity, but a liquid (such as paint, ketchup, or mayonnaise) which is lowered in viscosity and improved in fluidity when applied with pressure As in the case of the invention, when there is a possibility that the coating material will flow out from a thick coating to a thin coating, it is a suitable liquid in that the viscosity is increased at the time when the coating is spread on the coated surface after flowing with good pressure.

(Maintenance tray)

3 is a front schematic view of the holding tray 2. Fig. 2 and 3, the holding tray 2 for holding the curved base material 11 is provided at one end of the slit nozzle 3 in the slit direction (Y direction) A pair of sandwiching members 21 and 22 for holding the curved base member 11 at both ends of the curved base member 11 in the moving direction (X direction), and a pair of sandwiching members 21 and 22 for holding the curved base member 11, (23, 24) which are disposed between the curved base members (21, 22) and which support the curved base member (11) from below. Further, the holding tray 2 is provided at the other end of the slit nozzle 3 in the slit direction (Y direction) with respect to both ends of the curved base material 11 in the nozzle moving direction (X direction) A pair of sandwiching members 25 and 26 for holding the curved substrate 11 so as to sandwich the curved substrate 11 and a pair of sandwiching members 25 and 26 arranged between the pair of sandwiching members 25 and 26 in the X direction, And support members 27 and 28 which are supported more. The sandwiching member 21 and the support member 23 and the sandwiching member 25 and the support member 27 are disposed at both ends of the curved base member 11 in the slit direction (Y direction) And the holding members 24 and the holding members 26 and the holding members 28 are provided in pairs in the slit nozzle 3 in the slit direction (Y direction) At both ends of the curved base member 11, as a pair.

The nipping member 21 has a vertical portion 21a extending in the vertical direction and a horizontal portion 21b extending in the horizontal direction at the upper end of the vertical portion 21a. 3, the length A of the vertical portion 21a, the vertical length B of the slit nozzle 3 and the vertical portion 21a, the vertical length B of the slit nozzle 3 (initial position) and the vertical portion 21a, The length C in the X direction is constant. Therefore, even if the thickness and the curvature of the curved base member 11 change, the length A, the length B and the length C are constant when the curved base member 11 is sandwiched between the nipping members 21, The operating initial conditions of the application device 10 can be made constant. The sandwiching members 21, 22, 25 and 26 are formed such that the height of the lower end of the horizontal portion, that is, the length A of the vertical portion is equal to each other so that both end portions of the curved base member 11 are held at the same height.

Fig. 4 is an enlarged perspective view of the nipping member 21. Fig. The nipping members 22, 25, and 26 have the same structure as the nipping members 21, and the nipping members 21 will be described below by way of example. 4, the horizontal portion 21b of the sandwiching member 21 is formed such that the horizontal end surface of the lower end portion 21b2 is smaller than the upper end portion 21b1.

The sandwiching member 22 is provided so as to correspond to the length of the curved base material 11 in the nozzle moving direction X direction so that the distance between the sandwiching members 21, And is movable along the X direction. Specifically, the ball screw 201 engaged with the nipping member 22 is provided so as to extend inward in the X direction at the X-direction end portion of the table 20, and the handle 202 at the tip end portion of the ball screw 201 The nipping member 22 engaged with the ball screw 201 can be moved in the X direction. Further, since the nipping member 22 and the supporting member 24 are attached to the moving table 203 which is attached to the upper portion of the table 20 and movable in the X direction, the nipping members 22 22 move in the X direction, the movable table 203 also moves in the X direction, and the supporting member 24 also moves in the X direction. As a result, the sandwiching member 22 and the support member 24 are integrally moved in the X direction.

Similarly to the nip member 22, the nip member 26 is formed so as to adjust the distance between the nip members 25, 26 in accordance with the length of the curved base member 11 in the nozzle moving direction (X direction) And is movable along the X direction with respect to the nipping member 25. The support member 28 moves integrally with the sandwiching member 26 in the X direction.

The support members 23, 24, 27, 28 have the same structure. Hereinafter, the support member 23 will be described as an example. The support member 23 is provided with a support portion 23a which is in contact with the curved base member 11 at the upper end portion and the support portion 23a is movable in the up and down direction As shown in FIG. The top of the support portion 23a has a ball shape and is made of resin. Further, the support member 23 is provided with a pressing member 23b which is pressed in the vertical direction. The pressing member 23b is, for example, a spring and has a buffering function for supporting the curved base member 11. [ The pressing member 23b is accommodated in a tubular member 23c, and the supporting portion 23a is vertically moved up and down.

(Attachment of the curved substrate to the holding tray)

Figs. 5 to 7 are views for explaining the attaching operation of the curved base member 11 to the holding tray 2. Fig. First, as shown in Fig. 5, the nipping member 22 and the support member 24 are moved from the nipping member 21 and the support member 23 to X Direction to the farthest position.

Next, as shown in Fig. 6, one end of the curved base member 11 is sandwiched by the sandwiching member 21, and the curved base member 11 is sandwiched by the support portion 23a of the support member 23 in the up- 11 are supported by the support member 23 from the lower side.

7, the nipping member 22 and the supporting member 24 are moved toward the nipping member 21 and the supporting member 23 by moving the moving table 203 relative to the table 20 Approach. The other end of the curved base member 11 is sandwiched by the sandwiching member 22 and the curved base member 11 is sandwiched by the support member 24 To be supported by the lower side. The operation of the nipping member 25 and the support member 27 in the attachment corresponds to the operation of the nipping member 21 and the support member 23 and the nipping member 26 and the support member 28 ) Corresponds to the operation of the nipping member 22 and the supporting member 24. [

The application device 10 is operated as follows.

First, high-pressure air is supplied to the storage tank 1 to pressurize it, and the two-way valve 12 is opened. When the three-way valve 48 is set to the suction side and the motor 43 is rotated to the suction side, the coating liquid in the storage tank 1 passes through the first supply conduit 45, To the syringe pump 44. [0031]

When the charging to the syringe pump 44 is completed, the three-way valve 48 is switched to the discharging side. When the motor 43 is rotated to the discharging side, the coating liquid in the syringe pump 44 is supplied to the slit nozzle 3 from the three-way valve 48 through the second supply line 49. When the coating liquid in the syringe pump 44 is supplied to the slit nozzle 3, the control unit controls the motor 43 so that the supply pressure or the supply amount of the coating liquid becomes constant. The coating liquid is discharged onto the curved base material 11 on the holding tray 2 at the discharge port 3b of the slit nozzle 3 so that the supply pressure or the supply amount becomes constant and becomes a coating film.

According to the coating device 10 having the above-described configuration, the following effects can be obtained.

(1) The holding tray 2 holds the both ends of the curved base material 11 in the X-direction in the sandwiching members 21, 22 and 25, 26, Since the curved base member 11 is supported by the support members 23, 24 and 27, 28 more than the underside thereof, it is possible to hold the base material on the curved surface and also to hold the other curved base material 11 of R shape.

(2) The sandwiching members 21 and 25 and the support members 23 and 27 and the sandwiching members 22 and 26 and the support members 24 and 28 are provided at both ends of the curved base 11 in the Y direction The holding tray can be constituted by at least the nipping member and the supporting member.

(3) Since the supporting portions of the supporting members 23, 24, 27 and 28 are vertically movable, the supporting members 23, 24, 27 and 28 can be lifted up and down in accordance with the R- It is possible to adjust the position of the support portion in the vertical direction.

(4) Since the nipping members 22 and 26 are movable along the X direction, when the curved base member 11 is held, the nipping members 22 and 26 are wider than the width of the curved base member 11 It is easy to hold the curved base member 11 because both end portions of the curved base member 11 can be fitted. Further, the distance between the sandwiching members 21, 22 and 25, 26 can be adjusted in accordance with the length of the curved base member 11 in the X direction.

(5) Since the horizontal portions of the sandwiching members 21, 22, 25 and 26 are formed so as to have a smaller horizontal section at the lower end with respect to the upper end, the curved base member 11 and the sandwiching members 21, 22, 25 and 26 Can be reduced. As a result, the possibility of damage to the curved base member 11 due to the contact of the sandwiching members 21, 22, 25, and 26 can be reduced.

(6) Since the sandwiching members 21, 22, 25 and 26 sandwich the both end portions of the curved base 11 at the same height, the sandwiching members 11, The distance D to the application surface 11a is defined. As a result, even if the R shape of the curved base member 11 is changed, the initial position in which the slit nozzle 3 operates can be the same, and the operation control of the slit nozzle 3 can be facilitated.

(7) Since the support members 23, 24, 27 and 28 are provided with the pressing members which are pressed in the vertical direction, when the curved base member 11 is put on the support member due to its buffering property, It is possible to prevent damage to the curved base member 11 and to cope with the shape error of the curved base member 11 and to improve the supportability of the support members 23, 24, 27,

(8) Since the support member 24 moves integrally with the nip member 22 along the X direction and the support member 28 moves integrally with the nip member 26 along the X direction, It is possible to move in the X direction while maintaining the positional relationship between the nip member 22 and the support member 24 and to move in the X direction while maintaining the positional relationship between the nip member 26 and the support member 28 . Therefore, it is possible to easily adjust the positions of the sandwiching member 22, the support member 24, the sandwiching member 26, and the support member 28 for holding the curved base material 11.

(9) Since the upper end portions of the support members 23, 24, 27 and 28 have a hollow shape, the contact area between the curved base member 11 and the support members 23, 24, 27 and 28 can be reduced . As a result, the possibility of damage to the curved base member 11 due to the contact of the support members 23, 24, 27, 28 can be reduced. Since the upper end portions of the support members 23, 24, 27 and 28 are made of resin, the possibility of damage to the curved base member 11 due to the contact of the support members 23, 24, 27, .

(10) Since the nipping members 21 and 25 which are the initial position side of the slit nozzle 3 are fixed and the nipping members 22 and 26 move in the X direction to sandwich the curved base member 11, The initial position of the nozzle 3 and the nipping position of the curved base member 11 by the nipping members 21 and 25 are fixed. As a result, the operating initial conditions of the application device 10 can be made uniform, and the operation control of the slit nozzle 3 can be facilitated.

(11) The moving speed of the slit nozzle 3 is set such that the moving speed of the slit nozzle 3 is set at a distance from the slit tip end 3a to the coating surface 11a of the curved base member 11 in a state in which the supply pressure of the coating liquid to the slit nozzle 3 is kept constant. The slit nozzle 3 is moved so as to be in inverse proportion to the curved surface 11 and the coating liquid can be applied to the curved substrate 11 so that the surface of the coating liquid becomes flat.

(12) The moving speed of the slit nozzle 3 is set at a distance from the slit tip end 3a to the coating surface 11a of the curved base material 11 in a state in which the supply amount of the coating liquid to the slit nozzle 3 is kept constant. The slit nozzle 3 is moved so as to be in inverse proportion to the curved surface 11 and the coating liquid can be applied to the curved substrate 11 so that the surface of the coating liquid becomes flat.

(13) By applying an adhesive to the concave curved surface of the curved base material 11 with the coating liquid, an adhesive can be applied so that the surface of the adhesive becomes flat on the concave curved surface. As a result, the connection between the convex curved glass and the flat glass can be facilitated, and the one-side convex glass can be easily formed.

(14) When the coating liquid has thixotropy, the movement of the coating liquid applied to the curved base material 11 can be suppressed, and the coating liquid can be applied evenly within the predetermined area of the curved base material 11. If the coating liquid has a thixotropic property, the viscosity of the coating liquid after ejection becomes high. Therefore, even when the thickness to be coated during coating changes, as in the case of flat coating on the curved substrate 11, It is difficult for the coating liquid to flow to a thin place and change in thickness, so that the surface of the coating liquid can be finely finished.

In the above embodiment, two support members are provided in the nozzle moving direction (X direction), but one or three support members may be provided.

In the above embodiment, the sandwiching members and the support members are provided as a pair at both ends of the curved base member 11 in the slit direction (Y direction) of the slit nozzle 3, Three or more of them may be provided at predetermined intervals in the Y direction.

According to this configuration, since a plurality of the nipping members and the supporting members are provided at predetermined intervals in the slit direction, the holding tray can be constituted of a reasonable number of nipping members and supporting members.

In the above embodiment, the nipping members 22, 26 are movable along the X direction with respect to the nipping members 21, 25. However, the sandwiching members 21 and 25 may be movable along the X direction with respect to the sandwiching members 22 and 26. The sandwiching members 21 and 22 move integrally along the X direction so that the position of the intermediate line between the sandwiching members 21 and 22 is maintained and the sandwiching members 25 and 26 sandwich the sandwiching members 25 and 26 In the X direction so as to maintain the position of the intermediate line between the X direction and the X direction. This is achieved in the case of the nipping members 21 and 22 by moving the moving base 203 or 204 relative to the table 20 such that the position of the intermediate line between the nipping members 21 and 22 is maintained. Thus, even if the size of the curved substrate 11 is different, the curved substrate 11 can be always held at the center of the holding tray 2.

8 to 10 show that the nipping members 21 and 22 move integrally along the X direction so that the position of the intermediate line L between the nipping members 21 and 22 is maintained and the nipping members 25 and 26 The mounting operation of the curved base member 11 to the holding tray 2 in a case where it moves integrally along the X direction such that the position of the intermediate line L between the holding members 25 and 26 is maintained Fig. If the nipping member 21 is moved in the direction away from the nipping member 22 when the nipping member 21 and the nipping members 21 and 22 are moved integrally along the X direction so as to maintain the position of the intermediate line L between the nipping members 21 and 22, The nipping member 22 also moves in the direction away from the nipping member 21 by the same distance and moves the nipping member 21 in the direction approaching the nipping member 22, 21). ≪ / RTI > The same is true in the above-described manner that they move integrally along the X direction so that the position of the intermediate line L between the sandwiching members 25 and 26 is maintained. The tubular members 23c and 24c have bottom portions 23d and 24d and the bottom portions 23d and 24d are movable along the vertical direction with respect to the hole portions 23e and 24e.

8, the sandwiching member 21 and the support member 23 and the sandwiching member 22 and the support member 24 are placed in the holding tray 2, And the moving bands 203 and 204 are moved with respect to the table 20 to move them to the farthest position in the X direction with respect to each other.

Next, as shown in Fig. 9, the curved base member 11 is positioned between the nipping member 21 and the nipping member 22 with the robot hand 209 or the like.

Since the support member 23 moves integrally along the X direction with the sandwiching member 21 and the support member 24 is moved integrally with the sandwiching member 22 along the X direction, It is possible to move in the X direction while maintaining the positional relationship with the member 21 and the support member 23 and also to move in the X direction while maintaining the positional relationship with the nipping member 22 and the support member 24 . Further, since the support member 27 moves integrally along the X direction with the sandwiching member 25 and the support member 28 is moved integrally with the sandwiching member 26 along the X direction, Can be moved in the X direction while maintaining the positional relationship with the member 25 and the support member 27 and can be moved in the X direction while maintaining the positional relationship with the nip member 26 and the support member 28 . The holding member 21 and the holding member 23, the holding member 22 and the supporting member 24, the holding member 25 and the holding member 27 for holding the curved base member 11, The position of the support member 26 and the support member 28 can be easily adjusted.

In the above embodiment, the sandwiching member 21 and the support member 23, and the sandwiching member 25 and the support member 27 are arranged on the surface of the slit nozzle 3 in the slit direction (Y direction) The holding members 24 and the holding members 28 and the holding members 28 are provided at both ends of the slit nozzle 3 in the slit direction Y Direction) of the curved base member 11 at both end portions thereof. 11, the nipping member 210 and the support member 230, and the nipping member 220 and the support member 240 are arranged so as to extend over the entire length of the curved base member 11 in the Y direction Or may be provided so as to extend. As shown in Fig. 11, these may be extended one over the entire length of the curved base member 11 in the Y direction, or they may be divided in a proper manner in the middle and arranged at a predetermined interval.

According to this configuration, since the sandwiching members 21 and 22 and the support members 23 and 24 extend over the entire length of the curved substrate 11 in the Y direction, the retention of the curved substrate in the Y direction is improved .

Various changes and modifications may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
