Description

  The present invention relates to a powder distribution method and apparatus for distributing powder particles at a high speed in a predetermined distribution pattern on a fiber assembly conveyed by a conveyance belt. More specifically, the present invention relates to a disposable method. The present invention relates to a method and an apparatus for spreading an absorbent polymer at a high speed in a predetermined spreading pattern on a fiber assembly such as a nonwoven fabric sheet in the production of an absorbent used for absorbent articles such as diapers, sanitary napkins, and incontinence pads.

  Conventionally, absorbents used for absorbent articles such as disposable diapers, sanitary napkins, incontinence pads, etc., are obtained by spreading an absorbent polymer on a fiber assembly such as a non-woven sheet in a predetermined pattern and then spreading the absorbent. A separate sheet is attached to the nonwoven fabric sheet so as to sandwich the conductive polymer, or the nonwoven fabric sheet and the absorbent polymer distributed on the nonwoven fabric sheet are wrapped together by another sheet wider than the nonwoven fabric sheet. It is manufactured by cutting a sheet into a predetermined shape.

As a method of spreading an absorbent polymer on a fiber assembly in a predetermined spreading pattern, a method described in Patent Document 1 is known. In this method, a part of the continuous flow of the absorbent polymer powder supplied from a so-called powder feeder (screw feeder) is sucked by vacuum to disperse the powder intermittently. .
However, in the method described in Patent Document 1, the non-spreading part is collected by vacuum suction and sprayed in an intermittent pattern shape. There was a problem that it could not be obtained.

  As a means for solving such a problem, for example, there is a method described in Patent Document 2 or 3. In the method described in Patent Document 2, a granular material conveying belt is wound around a cylindrical body having a granular material receiving portion, and the granular material is transferred in a predetermined pattern on the granular material conveying belt. This is a method in which powder particles are distributed in a predetermined pattern on the pulp by sliding it down on the pulp. In addition, the method described in Patent Document 3 is a method for transferring a granular material fixing agent on a first sheet and / or a second sheet, and then conveying the granular material in a casing having a granular material supply port and a distribution port. This is a method in which a granular material is spread on a first sheet using a spreading apparatus having the following, and then the first sheet and the second sheet are bonded together.

  However, in the method described in Patent Document 2, when the powder is distributed on the powder transport belt, the protrusion of the powder distribution part (powder receiving part) provided on the cylindrical body is powder. Since it is in contact with the body transport belt, the absorbent polymer particles are transported while being in contact with the groove of the cylindrical body and the transport belt. For this reason, when the powder particles are distributed at high speed, the powder particles are distributed on the belt moving at high speed. There has been a problem that the granules are scraped up by the protrusions and blown in the downstream direction, and the granules are scattered. In particular, when a predetermined distribution pattern having a distribution part and a non-distribution part is distributed, the distribution pattern becomes unclear or powder particles are distributed to unnecessary portions. In addition, when the powder particles are scattered, the powder particles jump out of the production line, and there is a problem that the powder particles are wasted or the production environment is polluted.

On the other hand, in the method described in Patent Document 3, since the granular material distribution part is accommodated inside the casing, even if the granular material is distributed on the sheet at a high speed, the granular material is formed by the protrusions of the granular material distribution part. The body is not lifted up and scattered. In addition, since another sheet is bonded immediately after the powder body is distributed, the distribution pattern is retained and the powder body is not wasted.
However, the distribution device used in the method described in Patent Document 3 has a complicated structure, and can distribute powder particles in a predetermined pattern between the protrusions of the rotor provided in the casing and the inner wall surface of the casing. Need to be properly arranged. Moreover, although another sheet is bonded together immediately after powder body distribution and the distribution pattern is hold | maintained, depending on a product, another sheet may not be bonded together just after distribution like this.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the description of each drawing, the same elements are denoted by the same reference numerals.
FIG. 1 is a perspective view showing a preferred embodiment of the granular material spreading apparatus of the present invention. The granular material distribution device 1 of the present invention is rotated in the direction around the axis, with the conveying belt 2 that conveys the fiber assembly 5, and in close contact with the conveying belt 2 and rotates at substantially the same speed as the conveying belt 2. A fiber having a pattern ring 3 for spreading the granules 6 on the fiber assembly 5 in a predetermined spreading pattern, and a powder supply means 4 for feeding the granules 6 to the pattern ring 3, and continuously conveyed This is an apparatus for spreading the powder particles 6 on the aggregate 5 in a predetermined spreading pattern.

The pattern ring 3 used in the apparatus of the present invention will be described with reference to FIGS. FIG. 2 is an enlarged perspective view of the pattern ring 3 shown in FIG. 1, and FIG. 3 is an enlarged front view of the pattern ring 3 shown in FIG.
The pattern ring 3 includes a central cylindrical portion 31 having irregularities with a predetermined pattern for distributing powder particles on the outer peripheral surface, and side rings 32 and 33 installed at both ends of the central cylindrical portion 31. Here, the central axis of the central cylindrical portion 31 and the central axis of the side rings 32 and 33 are coaxial and correspond to the axis of the pattern ring 3. The pattern ring 3 rotates in the direction around the axis, rotates closely at the same speed as the conveyor belt 2 in close contact with the conveyor belt 2, and distributes the powder particles 6 on the fiber assembly 5 in a predetermined distribution pattern. To fulfill.

The pattern ring 3 has a so-called dumbbell shape in which the central cylindrical portion 31 is thin and the side rings 32 and 33 at both ends thereof are thick. That is, the side rings 32 and 33 have an outer diameter larger than the outer diameter of the central cylindrical portion 31. The difference H between the radii of the side rings 32 and 33 and the radius of the central cylindrical portion 31 is preferably larger than the thickness of the fiber assembly 5 being conveyed, and is 1.1 to 5 times the thickness of the fiber assembly 5. It is preferable. Further, the length L1 of the central cylindrical portion 31 is larger than the width L2 of the fiber assembly 5 to be conveyed.
The pattern ring 3 is disposed in close contact with the conveyor belt 2 in the apparatus of the present invention. At this time, the side rings 32 and 33 are in close contact with the transport belt 2 but do not contact the transported fiber assembly 5. Further, the central cylindrical portion 31 does not contact either the transport belt 2 or the transported fiber assembly 5.

  On the outer peripheral surface of the central cylindrical portion 31 of the pattern ring 3, a concavo-convex portion having a predetermined pattern for spreading the granular material 6 is formed. The granular material 6 supplied from the granular material supply means 4 is supplied to the concave portions 311 separated by the convex portions 312 and distributed. In addition, the non-spreading region is formed on the fiber assembly 5 by the continuous convex portions 313.

  The transport belt 2 plays a role of continuously transporting the fiber assembly 5 from one side to the other. The transport belt 2 is guided by roll groups 21 to 26 including a plurality of free rolls (rolls without drive) and guide rolls, a drive roll 27 and the pattern ring 3, and is in close contact with the side rings 32 and 33 of the pattern ring 3. And is configured to travel in the same direction as the rotation direction of the pattern ring 3 (in the direction of arrow A in FIG. 1) in synchronization with the pattern ring 3.

  The granular material supply means 4 serves to supply the granular material 6 to the pattern ring 3. The granular material supply means 4 is arranged on the upper portion of the central cylindrical portion 31 of the pattern ring 3 and supplies the granular material 6 to the concave portion 311 provided with the central cylindrical portion 31 of the pattern ring 3.

  Next, the operation of the pattern ring 3 in the apparatus of the present invention will be described with reference to FIGS. FIG. 4 is an enlarged side cross-sectional view of the pattern ring 3 shown in FIG. 1 and shows a state in which powder particles are distributed in a predetermined pattern on the fiber assembly.

As shown in FIGS. 3 and 4, the transport belt 2 is wound around the side rings 32 and 33 of the pattern ring 3. The central cylindrical portion 31 of the pattern ring 3 is not in contact with either the transport belt 2 or the transported fiber assembly 5, and the side ring 33 of the pattern ring 3 is in close contact with the transport belt 2, but is transported. There is no contact with the assembly 5. Although the side ring 32 is not shown in FIG. 4, it is the same as the side ring 33.
Further, the powder and granular material supply means 4 is disposed on the upper part of the central cylindrical portion 31 of the pattern ring 3. Here, the insertion port 41 of the powder and granular material supply means 4 is arranged so as to be closed when the convex part 313 of the pattern ring passes (when not distributed).

The granular material 6 is supplied from the inlet 41 of the granular material supply means 4 to the recess 311 formed in the central cylindrical portion 31 of the pattern ring 3. The pattern ring 3 rotates at a high speed, and the powder particles 6 are spread on the fiber assembly 5. At this time, since the granular material 6 is pressed and fixed onto the fiber assembly 5 by centrifugal force, the distribution pattern of the granular material 6 is not broken and a predetermined pattern is maintained.
Further, the central cylindrical portion 31 of the pattern ring 3 is not in contact with the fiber assembly 5, and a gap is provided between the central cylindrical portion 31 of the pattern ring 3 and the fiber assembly 5. The powder particles 6 distributed on 5 do not come into contact with the pattern ring 3. Therefore, when the conveying belt 2 is separated from the pattern ring 3, the powder particles 6 are not spun up by the convex portions 312 of the pattern ring 3, and the powder particles 6 do not scatter. For this reason, a clear distribution shape can be maintained, without the distribution pattern of the granular material 6 collapsing.

Referring to FIG. 3 again, the length L1 of the central cylindrical portion 31 is larger than the width L2 of the fiber assembly 5 to be conveyed. Therefore, the fiber assembly 5 is not crushed by the side rings 32 and 33 of the pattern ring 3.

There is nothing. Therefore, the granular material 6 is not splashed up by the convex part 312 of the pattern ring 3, and the granular material 6 does not scatter.

In the conventional powder distribution device, when the powder is distributed, the fiber aggregate is pressed directly against the uneven portion (spread portion) of the pattern ring together with the conveyor belt, and the powder on the fiber aggregate is It was conveyed while in contact with the concave portion of the pattern ring. In such an apparatus, when the powder particles are distributed at a high speed, the powder particles that are in contact with the concave portions are splashed and scattered by the convex portions when the conveyor belt is separated from the pattern ring. There was a problem.
On the other hand, in the granular material spreading apparatus of the present invention, as described above, the conveyor belt 2 is wound around the side rings 32 and 33 of the pattern ring 3, and the central cylindrical portion 31 and the fiber assembly of the pattern ring 3 are wound. Since a gap is provided between the conveyor belt 5 and the conveyor belt 2, when the conveyor belt 2 is separated from the pattern ring 3, the granular material 6 is not sprung up by the convex portion 312 of the pattern ring 3. No scattering occurs.

  After the powder particles 6 are spread on the fiber aggregate 5, another sheet is bonded to the fiber aggregate 5 so as to sandwich the powder particles (absorbent polymer) 6 spread on the fiber aggregate 5, and absorbed. By cutting the sheet at a portion where the conductive polymer 6 is not distributed and making it into a predetermined shape, an absorbent body used for absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads can be manufactured.

  The conveyor belt 2 is not easily entangled with the fiber assembly 5 and has an appropriate friction against the fiber assembly 5 so that no slip occurs between the fiber assembly 5 and the conveyor belt 2 when the fiber assembly 5 is transported. It is preferable that it is made of a material having a force and has a flat surface.

By sucking the conveying belt 2 having air permeability by the suction portion 71, the fiber assembly 5 can be adsorbed to the conveying belt 2, and thereby the fiber assembly 5 is separated from the conveying belt 2 during the conveyance and is patterned. It is possible to reliably prevent contact with the ring 3. Although it does not specifically limit as a conveyance belt which has air permeability, For example, a punching belt, a mesh belt, etc. are mentioned.

In addition, as shown in FIG. 6, it is also preferable to provide a granular material collection unit 43 between the granular material supply means 4 and the pattern ring 3. When the powder body 6 is supplied from the powder body supply means 4 to the pattern ring 3, the powder body 6 is sucked and collected by the powder body recovery unit 43 before being supplied to the pattern ring 3. Supply of the granular material 6 to the area | region which hits the part (non-spreading part) 313 can be stopped. When sucking the granular material 6 by the granular material collecting unit 43, an air introduction part 42 is provided to lower the internal pressure of the pipe so that even the granular material 6 to be supplied to the pattern ring 3 is not sucked up. It is preferable not to do so.
