Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating apparatus used for applying a liquid to a surface of a sheet-like substrate, and more particularly, to a coating apparatus which contacts a surface of a continuously running sheet-like substrate. The present invention relates to a continuous line pattern coating apparatus for applying a coating solution to the surface in a line pattern in a state.

[0002]

2. Description of the Related Art There are various means for applying a coating liquid to the surface of a sheet-like base material. However, when the coating liquid has relatively low fluidity, a contact-type applicator is used. There are many.

The basic structure of a conventional general coating apparatus in the form of a contact-type applicator is schematically shown in FIGS. In the figure, a main body denoted by reference numeral 1 has a substantially rectangular cylindrical shape in which an upper end and a lower end are opened and a slurry 2 is accommodated therein, and a support base 3 is disposed at a lower end opening. The sheet-like base material 4 to which the slurry 2 is to be applied continuously passes through a gap between the base material 3 and the support base 3.

[0004] One of the side walls of the main body 1, that is, the lower end face of the side wall located on the downstream side in the moving direction of the sheet-like substrate 4, has a clearance C of a predetermined width with respect to the surface of the sheet-like substrate 4. As it is formed, it is placed at a position slightly higher than the simple surface of the other side wall, and this side wall forms a clearance setting wall 1a that regulates the thickness of the clearance C.

[0005] The coating operation is performed by continuously moving the sheet-like substrate 4 in the direction of the arrow in the figure while supplying the slurry 2 to the space in the main body 1. In the main body 1, the slurry 2 rides on the surface of the sheet-like base material 4 moving along the bottom surface of the main body 1 and moves together with the sheet-like base material 4 as a coating layer, but contacts the inner surface of the clearance setting wall 1a. Accordingly, only the thickness of the clearance C formed at the lower end thereof is allowed to exit the main body 1 together with the sheet-shaped base material 4, and as a result, the thickness of the clearance C is reduced on the surface of the sheet-shaped base material 4. A coating layer 2a of a corresponding thickness is formed.

If a coating apparatus as shown in FIGS. 1 and 2 is used, it is possible to form a coating layer 2 a having a constant thickness on the surface of the sheet-like base material 4. The coating layer 2a formed here uniformly covers almost the entire surface of the sheet-like substrate 4, and the only parameter that can be set is the thickness of the coating layer 2a by changing the thickness of the clearance C. .

[0007]

For example, in the case of a sheet-like absorber having a layer of a particulate polymer absorber provided on the surface of a sheet-like substrate, a uniform thickness of the particulate high-molecular absorber is applied over the entire surface of the sheet-like substrate. It is known that when a molecular absorber layer is provided, the flexibility is poor, the liquid tends to be blocked, and the diffusivity is poor. Absorbent products such as diapers that use such a sheet-like absorbent material with poor flexibility are difficult to fit on a complicated curved surface of the human body, and cannot follow the movement of the human body. It can cause serious defects. Further, in the case of a sheet-shaped absorber which is liable to cause blocking of the liquid and has poor diffusion properties, when the liquid is repeatedly absorbed as in a diaper or the like, the first time is not problematic,
From the second time onward, there is also a problem that the diffusion of the liquid to the portion that still has the liquid absorbing ability is hindered by the blocking phenomenon.

[0008] An effective means for solving the above-mentioned problem is to make a portion coated with a polymer absorber and a portion without a coating coexist. More generally, by applying intermittent coating so that the coated part becomes linear, the non-coated part becomes a line, becomes a flexible and bendable part, and acts as a channel for liquid diffusion. Can be. From such a background, it is industrially important to manufacture a sheet-shaped absorber having a continuous line-shaped pattern.

However, since it is not easy to stably coat a slurry which is difficult to handle in a continuous line pattern, an apparatus which can be manufactured on an industrial scale has not yet been provided.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to improve the flexibility of a sheet material provided with a coating layer on its surface,
It is another object of the present invention to provide a coating apparatus capable of improving the diffusivity without causing blocking of the liquid.

According to the present invention, a slurry supply opening, a slurry discharge opening, and a surface of the sheet-like substrate are coated to form the slurry while being in contact with the moving sheet-like substrate. A main body having a clearance setting wall for setting a clearance that regulates the thickness of the slurry, and a partition member attached to the main body, wherein the partition member contacts the discharge opening with the surface of the sheet-shaped substrate. A plurality of divided portions having a length reaching at least the vicinity of the clearance with respect to a direction orthogonal to the moving direction in a state in which the divided portions are not present, and a connecting portion coupling the divided portions. When applied to the surface of the sheet-like substrate through a plurality of formed slurry outlets, the width of the slurry outlet and the clearer Characterized in that it is configured to form a line-shaped pattern corresponding to the thickness of the scan continuous line pattern coating apparatus is provided.

[0012] The dividing portion may be configured so as to contact the surface of the sheet-like base material by its own weight and the weight of the supplied slurry, or the front end thereof may be in contact with the surface of the sheet-like base material. The partition member may be fixed to a position where it can always contact, and preferably, the partition member is detachably attached to the main body.

In another preferred embodiment of the invention, the split extends through the clearance. In the case where a suction zone for separating the liquid component of the slurry is provided at the subsequent stage of the coating device, the divided portion extends through the clearance to reach the suction zone.

[0014] Further, the dividing portion may have an engaging portion which engages with the tip of the clearance setting wall for setting the clearance, or may be fixed to the tip of the clearance setting wall.

[0015] The connecting portion for connecting the plurality of divided portions to each other includes:
It may be located at the same height as the divided portion with respect to the surface of the sheet-shaped base material, but is preferably located at a position higher than the divided portion with respect to the surface of the sheet-shaped base material.

The coating apparatus of the present invention can be widely used for applying an arbitrary slurry to various types of sheet-like substrates, but one of the most suitable uses is a liquid-permeable sheet-like substrate. This is an application in which a slurry of a particulate polymer absorber or a slurry of a mixture of microfibrillar fine fibers and a particulate polymer absorber is applied to the surface of a material.

A sheet material provided with a coating layer coated with a plurality of continuous linear patterns parallel to each other is a portion of only the sheet-like substrate existing between two adjacent linear patterns, that is, the coating layer is not provided. It bends easily at the non-existing portion, thereby exhibiting good flexibility, and serves as a liquid channel at the time of the second and subsequent absorption to facilitate diffusion.

The slurry discharge openings are arranged so as to face each other at a predetermined interval, and the sheet-like base material 12 can move in the direction of the arrow in the drawing through the gap between the main body 10 and the support base 11. The lower end surface of the side wall of the main body 10 located on the downstream side with respect to the moving direction of the sheet-shaped base material 12 has another side wall so as to form a clearance C having a predetermined width with respect to the surface of the sheet-shaped base material 12. This side wall forms a clearance setting wall 10a that regulates the thickness of the clearance C.

Further, the main body 10 is provided with a partition member 13 for partially closing the lower end slurry supply opening. This partition member 13 is, as shown in FIG.
It is a comb-shaped one that includes a plurality of substantially rectangular plate-shaped divided portions 13a arranged in parallel with each other, and a plate-shaped connecting portion 13b that connects the divided portions 13a to each other at one end. As shown in FIG. 4, the partition member 13 is formed such that each of the divided portions 13a is formed of a sheet-like base material 1 indicated by an arrow.
2, the tip thereof approaches or contacts the inner surface of the clearance setting wall 10 a of the main body 10, whereby a plurality of (six in the illustrated example) slurry discharge openings are provided. It is divided into independent slurry outlets.

If at least the leading end of the divided portion is flexible, the contact of the divided portion with the surface of the sheet-like base material is made by its own weight and the weight of the supplied slurry. There is also.

In the continuous line pattern coating apparatus constructed as described above, the slurry is supplied from the slurry supply opening at the upper end of the main body 10, and at the same time, the sheet base material 12 is supplied to the slurry discharge opening at the lower end of the main body 10. It is continuously moved in contact with The slurry 14 stored in the main body 10 adheres to the surface of the sheet-shaped base material 12 through a plurality of slurry outlets divided by the dividing portion 13a of the partition member 13, and is accompanied by the movement of the sheet-shaped base material 12. And in the process, is scraped at the lower end of the clearance setting wall 10a. This allows the slurry to:
The surface of the sheet-like base material 12 is coated in a continuous linear pattern having a width corresponding to the width of the slurry outlet partitioned by the dividing portion 13a and the thickness of the clearance C. A layer of slurry coated in this line,
A layer of solidified material that loses part or most of the liquid after coating is called a `` line-shaped coating layer ''
And denoted by the reference numeral 100.

Conditions desired for coating the slurry with such a continuous line pattern include the following.

Condition 1) The entire lower surface of the divided portion 13a of the partition member 13 must be in uniform contact with the surface of the sheet-like substrate 12.

Condition 2) There is no gap between the tip of the dividing portion 13a and the inner surface of the clearance setting wall 10a.

Condition 1) is that the partition member 1
3 can be easily satisfied by properly determining the mounting position, and even when the dividing portion 13a has a certain degree of flexibility, the dividing portion 13a can be formed by its own weight and the weight of the slurry added from above. Is pressed against the surface of the sheet-like substrate 12, so that it is usually unnecessary to provide any special fixing means.

However, if it is desired to engage or fix the distal end of the divided portion 13a with the clearance setting wall 10a in order to more reliably satisfy the condition 2), FIGS. A structure as shown in c) can be adopted. FIG. 6A shows that the tip of the divided portion 13a is extended to the position of the outer surface of the clearance setting wall 10a, and the thickness of the portion located below the clearance setting wall 10a is made substantially equal to the clearance C to eliminate the gap. 6 (b) shows the case where the sealing performance is improved, and FIG. 6 (b) shows the case where the thickness of the same portion is made slightly smaller than the clearance C.
The engagement of the inner wall side of the clearance setting wall 10a with the divided portion 13a prevents the slurry from leaking. FIG.
As shown in (c), the tip of the divided portion 13a is extended to the outside of the clearance setting wall 10a.
Engaging portion 1 that engages with the outer surface of clearance setting wall 10a
31 may be provided to eliminate the gap.

In the example shown in FIGS. 3 to 5, the plurality of divided portions 13a and the connecting portion 13b connecting them are located at one end of each divided portion 13a, that is, at the most upstream end in the moving direction of the sheet-like base material 12. It is provided integrally, this is 1
It has the advantage of being suitable for being formed from a single sheet by means such as punching. However, the connecting portion 13b is
The shape, thickness, and mounting position can be arbitrarily selected as long as the slurry flowing down from the slurry outlet between 3a and onto the sheet-like base material 12 does not obstruct the passage passing through the clearance C as it is.

The partition member 13 shown in FIG. 7 is a separate member extending in a direction perpendicular to these at substantially the center in the length direction of the plurality of divided portions 13a arranged in parallel with each other at a predetermined interval. The connection part 13c is arrange | positioned so that it may ride on each division | segmentation part 13a, and is mutually connected in the intersection part with each division part 13a. FIG. 8 shows an example in which an engagement groove 132 is provided on the upper surface on the downstream side of each of the divided portions 13a so as to engage with the distal end portion of the clearance setting wall 10a. 13c shows the configuration connected. Alternatively, as shown in FIG.
It is also possible to provide both a connecting portion 13b for connecting 3a and a connecting portion 13c in FIG.

Since the above-mentioned partition member 13 is used while being sandwiched between the main body 10 and the sheet-like base material 12, it moves in the direction parallel to the surface of the sheet-like base material 12 with respect to the main body 10. It is sufficient that they are engaged to such an extent that they do not engage with each other, and it is not always necessary to fix them to the main body 10. However, if it is desired to fix them, for example, a fixing means as shown in FIGS. You may.

That is, in the example of FIG. 10, a connecting portion 13d extending upward along the upstream inner wall surface of the main body 10 is provided at the upstream end of the dividing portion 13a.
Are fixed with bolts 15. In the example of FIG.
A clearance setting wall 10a is provided at the downstream end of the divided portion 13a.
A connecting portion 13e extending upward along the inner wall surface is provided, and the connecting portion 13 and the clearance setting wall 10a are connected to each other by bolts 15a.
It is fixed with. Alternatively, as shown in FIG. 12, the distal end of the divided portion 13a extends through the clearance C to the downstream side thereof, and at this extended portion, the clearance setting wall 1 is formed.
0a is provided with a connecting portion 13f extending upward along the outer wall surface,
The connecting portion 13 and the clearance setting wall 10a may be fixed with bolts 15. Further, at least two of the fixing means shown in FIGS. 10 to 12 can be used together.

Next, a second embodiment of the present invention will be described. In the use form of the coating apparatus of the present invention, when a slurry having physical properties suitable for applying to a sheet-like substrate is used, each divided portion of the partition member,
It is not necessary to extend the clearance setting wall provided on the main body more downstream than the downstream surface. However, when the fluidity of the slurry to be used is relatively high and there is a possibility that the slurry will flow in the horizontal direction after being applied in a line on the sheet-like substrate, the tip of the divided portion should be moved beyond the outer surface of the clearance setting wall. It may be extended to an arbitrary position on the downstream side.

The partition member 13 shown in FIGS. 13 and 14
Divides the dividing portion 13a into the clearance setting wall 1 of the main body 10.
An extension 133 extends downstream through a clearance C formed at the lower end of Oa. This extension 13
3 functions to regulate the edge of the linear slurry until the linear slurry formed on the sheet-shaped substrate 12 by passing below the main body 10 loses fluidity. Therefore, the length of the extension portion 133 can be set to an optimal value according to conditions such as the fluidity of the slurry used and the solidification speed thereof.

In the example shown in FIG. 15, the connecting portion 13g is arranged along the downstream wall of the clearance setting wall 10a.
However, the extension portions 133 of the divided portions 13a which are orthogonal to this are connected to each other, thereby preventing the extension portions 133 from moving or vibrating in a direction orthogonal to the moving direction of the sheet-shaped base material 12. . This connecting portion 13g is
3 may be further provided on the free end side.

Further, when the sheet-like base material on which the slurry has been applied is guided to the suction device at a later stage of the coating device for drainage, the extension of the partition member should be extended above the suction device. Can be.

More specifically, referring to FIGS. 16 and 17, the coating apparatus 10 is provided above the continuously running sheet-shaped base material 12 and below the sheet-shaped base material 12. Also on the downstream side, a suction device 20 is arranged.

The coating apparatus 10 has substantially the same structure as that shown in FIGS. 13 and 14, including a dividing portion 13a for dividing the discharge opening surface of the main body 10 having the clearance setting wall 10a into a plurality of slurry outlets. Having. Further, the suction device 20 includes a receiver 21 having a width substantially equal to the entire width of the sheet-shaped base material 12 and having an open upper surface.
The port 22 formed on the bottom of the receiver 21 is connected to a suction device (not shown). The upper end open surface of the receiver 21 is arranged at a position where it can come into contact with the lower surface of the moving sheet-like base material 12. Therefore, due to the negative pressure inside the receiver, the sheet-like base material A suction zone 23 for sucking the air 12 is formed. And the dividing unit 13
The extension 133 of “a” has reached a position near the downstream end of the suction zone 23 or beyond the downstream end.

When the sheet-like substrate 12 moves continuously and the slurry is supplied from the coating apparatus 10 at the same time,
According to the above-described operation, the slurry is coated on the sheet-like base material 12 in a continuous line-like pattern to form a linear coating layer 100. The line-shaped coating layer 100 moves to the downstream side together with the sheet-shaped base material 12, and when reaching the suction zone 23, air is sucked into the suction container 21 from above. In the portion where the linear coating layer 100 does not exist, the extension 1
33, only the portion where the linear coating layer 100 is provided is open. Therefore, the outside air is drawn into the suction device 20 only through the line-shaped coating layer 100 and the sheet-shaped base material 12 therebelow, and the liquid contained in the line-shaped coating layer 100 is accompanied by this air flow. The minute is aspirated and the liquid is removed. If the extension 133 is not present, the outside air will only pass through the part where the linear coating layer 100 is not present and therefore has a significantly lower resistance, and no effective drainage will take place.

[0039]

According to the present invention as described above,
The slurry can be easily and stably coated on the surface of the sheet-like substrate in a continuous line pattern. Moreover, the structure is simple, and if a plurality of partition members having different sizes and numbers of divided portions are prepared, the pattern of the slurry formed on the sheet-like base material can be changed simply by replacing the partition members. Is possible.

Further, when the slurry is a slurry of a particulate polymer absorber, or a slurry of a mixture of microfibrillar fine fibers and a particulate polymer absorber,
The manufactured product is a sheet-shaped absorber in which a high-absorbent layer is provided on a sheet-shaped substrate in a continuous line pattern. This sheet-shaped absorber, between the high-absorbent layer, because there is only a portion of the sheet-shaped base material without the high-absorbent layer,
It is highly flexible in the width direction where it is apt to be rough and has good diffusibility, and can be advantageously used for various absorbent products such as diapers for infants and adults.
