Description of the Invention: [Technical Field] The present invention relates to a web coating device for continuously or intermittently applying a predetermined coating liquid to a moving web. In particular, it relates to a winding coating apparatus which can apply a coating liquid evenly and uniformly in the case where a defect such as bending or slack exists in the wound body itself. [Prior Art] It is required to apply a predetermined coating liquid to a surface of a wound material, such as a metal foil or a resin film, in a film and uniformly. For example, as shown in FIG. 4, it is present on the metal foil 1〇1, such as an aluminum foil or a copper foil, and it is set as the thin film (for example, although it is the dry state or the wet state, it is the thickness of 0.5-15 grades. An anchor coat 108, and sometimes there is a case where a relatively thick protective coating 1〇3 is provided thereon. For example, in a secondary battery, a capacitor or the like, the deposition of a substance on the metal foil 〇1 can be prevented by performing such an anchor coat before the protective coating. Further, since the adhesion between the metal foil 101 and the protective coating layer 1 3 can be improved, it is expected to improve the battery performance or the long-term durability. Further, in the case of optical film use, etc., it is required to apply a film of 〇 5 to 1 "m in a wet state. As a general method of performing film coating with a uniform thickness, for example, as shown in FIG. 5, the wound material 111 is moved on a backup roll 112, and is disposed on the backup roll 112 as a coating. The coating head of the liquid supply means 100131660 3 201228740 113 'The gap between the outlet of the slit-shaped discharge port U4 of the coating U3 and the surface of the backup roll 112' is precisely adjusted and applied to the winding 111 The method of applying the coating film 115 to the moving wound material 111 in the case where the film thickness of the door is equal or slightly larger (in the present case, 'this method is called "combination Sewing cloth. However, in this co-roller coating method, 'there is a high precision requirement for each component itself or (4), and in most cases it is difficult to meet its accuracy requirements' especially in most cases it is difficult to satisfy the slit-like soil. The gap between the exit of the outlet 114 and the surface of the support pro 112 requires the precision of the pole door, and in this case, even if a high-precision gap adjustment can be performed, when a foreign object enters the gap portion, The foreign matter is stuck, and the obvious coating defect is generated. * The winding ill is broken * by the accompanying & the winding of the winding 1 with the accompanying air flow, etc., may occur in the longitudinal direction of the winding 1 and in the width direction of the winding 111 The distribution of many stripe-like coatings is uneven (mostly in the form of striped colors). Itb-striped coating unevenness also occurs in the winding material 6 as shown in the coating head 100131660 1 itself. When there is a case where the thickness is uneven in the direction of the money, or when the accuracy of the assembly is not good, it is known that, for example, the opening is provided near the exit of the slit-shaped discharge port 122. The dust suction suction 23 is for suppressing the application of the air mixed with the helium gas and the melon powder while the pressure is reduced on the upstream side of the coating portion. In this coating method, 隹Λ The problem of uneven coating of the stripe caused by the airflow and the airflow can be reduced by 201228740, but the gap between the outlet of the slit-shaped discharge port 122 and the surface of the support 112 is extremely high. The requirements have not changed, so the coating due to the above-mentioned foreign matter is missing. The problem of the breakage of the winding material, or even the unevenness of the width of the winding material 111 due to the uneven thickness or the poor precision of the assembly, is still present. For this residual problem, For example, as shown in FIG. 7, the coating head 113 is disposed on the free path (air path) of the moving winding 111 (for example, an air path formed between the rollers 131, 132) for approaching and moving away. The direction of the exit of the slit-shaped discharge port 114 of the coating head 113 can be slightly displaced to provide a moving wrapper 111 (in this case, this method is referred to as "offroll coat"). (for example, the manner of the patent document υ). In the one-roller coating method, the gap between the outlet of the slit-shaped discharge port 114 and the surface of the wound material U1 is zero (that is, the surface of the slit-shaped discharge port U1 and the slit-shaped discharge port 114 is zero. The outlet contact), the surface of the winding material m can be displaced in the direction of σ which is close to and away from the slit-like discharge σ 114, so that at least the entanglement of the wound 111 by the foreign matter being caught can be removed, so Film coating is one of the effective methods. However, if only the off-roll coating method is used in this way, the wound material 111 itself may be defective (sometimes in the longitudinal direction, or locally, where there is a flatness such as slack, etc.), or the moving winding (1) The swaying or the like may cause the wound material 111 to contact the front end portion of the coating head 113 (the outlet portion of the slit-shaped discharge port 114) unevenly in the width direction (for example, the contact pressure may become uneven) or Partially made of silk), or the resulting stripe 100131660 201228740 shape or local uneven coating. Although the sway of the winding 111 can be suppressed to some extent by shortening the distance between the rollers 131 and 132, it is difficult to suppress the coating unevenness due to the defect of the wound 111 itself as described above.

In the winding coating apparatus of the present invention, at least one of the upstream side and the downstream side of the slit-shaped discharge port of the coating liquid supply means is provided with a pressurizing chamber or a decompression chamber for passing In the case of the pressurizing chamber, the pressing force acts on the winding material, and the pressure recording object can be locally displaced in the direction away from the inside of the pressurizing chamber. In the case of the chamber, the suction force is made to test the winding, and by the suction force, the winding can be displaced in a direction close to the inside of the pressure reduction to the inside. When the money shirt is in the presence of a bend (a bend in the shape of a weeping), it is considered to be the secret of the two reference lines extending in the direction of the length direction and the direction orthogonal to the length direction. The edge of the edge is different...the other edge is different. At this time, the winding is often Γ=Γthe free path (air path) produces poor planarity (ie, the state of 2 壬·^松他) ^, even in the volume When there is a defect such as 1 =:::: in the winding itself, the winding may sometimes be directly moved by the cancer. In the case of the above-mentioned reduction itself, there is a length: when the local loose material is used (4) If the difficult object is directly corrected, the slit-shaped discharge port of the coating liquid supply means is the cause of uneven coating. Therefore, in the present invention, the upstream side of the slit-shaped discharge port is The middle and upper speeds of the downstream side are at the position of 100131660. With 201228740, the force of the winding object is applied to the back by the force of the winding, the ▲, or the decompression chamber. The defect of the winding itself is caused by the actual material tilting at the position of the pressurized chamber (four), so that the slit-like spout can be made. Partially revenge, which is the secret of the volume itself. The force of the suction or the suction force, g is applied to the winding material by the self-pressurizing chamber or the decompression chamber. The pressure or suction force acts on the entire winding area of the moving coil at any time, so that the absorption of the defect is also automatically performed throughout the entire area of the outlet. Thus, the position of at least one of the slit-shaped ejection side and the downstream side absorbs the winding object 曰, so that the defect of the stretched product itself does not substantially appear in the slit shape lx} port y/jy m> , especially 1 (four) ',, 'to make the effect of the defect on the coating is eliminated, and the coating of the uniform sentence can be applied in particular to the uniform coating of the film. In addition, the pressure chamber may be provided at least at the position of the slit-shaped discharge port of the coating liquid supply means and the downstream side, and even if it is disposed in the lower 1 It (four)' The defect absorption effect of the winding material on the downstream side is via the position of the winding material and the cut-to-slot outlet. In order to transport the wound material to the position of the slit-shaped discharge port in a state in which the defect of the wound body itself has been absorbed, it is possible to more reliably realize that the desired uniform soil cloth is at least pressurized. The chamber or the decompression chamber is placed in advance on the upstream side of the slit-shaped discharge port. In the above-mentioned Japanese-style wound coating, the pressure chamber or the 100131660 201228740 pressure chamber is disposed on the opposite side of the coated surface of the wound material. In particular, when the pressurizing chamber or the decompression chamber is provided on the downstream side of the slit-shaped discharge port, since the coated wound material passes through the position of the pressurizing chamber or the decompression chamber, it is prevented from being contacted or the like. The coated surface is adversely affected by the fact that it is preferably disposed on the opposite side of the coated surface. When the pressurizing chamber or the decompression chamber is provided on the upstream side of the slit-shaped discharge port, it may be provided on the coated surface side as long as the surface of the wound material is not damaged. Further, in the winding coating apparatus of the present invention, the configuration of the pressurizing chamber or the decompression chamber is not particularly limited, but the pressurizing chamber or the decompressing chamber can be, for example, pressurized gas (for example, The pressurized air is introduced into the chamber or formed by drawing a gas (for example, air) from the chamber. Further, as a more specific configuration of the pressurizing chamber or the decompression chamber, it is possible to adopt a configuration in which one surface is formed by the winding material as described above, and the other surface is formed, for example, by the chamber forming member. Further, in the winding coating apparatus of the present invention, the coating portion may be subjected to roll coating, but (4) the slit-shaped discharge port of the coating liquid supply section is basically disposed in the winding. _ coating on the air path of the object. That is... = basically set to apply from the roll to prevent the shortcomings due to the application of money, that is, due to the foreign matter card (four) shirt failure, the essential material: not clear, the side directly play away from her strip = the above pressurized room or The setting of the decompression chamber can be used to avoid the influence of the defect on the coating, and the defect of the % & itself can be used to eliminate the uniform coating of the film. The uniform coating which is desired in the present invention, and the preferred embodiment of the winding coating of the present invention, as shown in FIG. 201228740, is as follows: before and after the winding direction of the coating liquid supply means, The winding conveyance I is positioned to position the moving path of the winding object at the exit position of the slit-shaped discharge port, and the pressurizing chamber or the decompression chamber is provided on the upstream side of the winding conveyance roller on the upstream side. And a position of at least one of the downstream side of the winding conveyance roller on the downstream side.
