[Configuration of void volume measuring device 1]
The gap amount measuring device 1 of the present invention is based on the distance to the measurement object, more specifically, the gap between the human body model and the wearing surface of the wearable object based on the three-dimensional shape of the measurement object calculated from the distance. Calculate the amount. The measurement of the three-dimensional shape includes, for example, receiving reflected light of a predetermined laser beam (light beam) projected onto the measurement object, obtaining distance information based on the principle of triangulation, and converting it to three-dimensional data. Can be realized. Referring to FIG. 1, the void amount measuring device 1 of the present invention includes a distance measuring device 10, a human body model 20, and an arithmetic device 30.

  The distance measuring device 10 is a measuring device that measures the distance of an object to be measured, and includes a sensor unit 11, a pedestal unit 12, and a guide unit 13.

The sensor unit 11 is a laser distance meter that measures the distance to a measurement object by projecting a point or linear laser beam. In this embodiment, the LK-G500 manufactured by KEYENCE is used. Yes. When measuring the distance information, the sensor unit 11 outputs the distance information to the control unit 31 of the arithmetic device 30.
The pedestal portion 12 is a base on which a measurement object whose distance is measured by the sensor portion 11 is placed, and is provided below the sensor portion 11.

  Here, in this embodiment, since the measuring object to be measured using laser light is the three-dimensional human body model 20, in order to measure the surface shape of the entire human body model 20 as the measuring object, the sensor unit 11 and the human body model 20 need to be moved appropriately.

  Therefore, the distance measuring device 10 includes a guide portion 13 that restricts the movement of the pedestal portion 12. In the present embodiment, the guide portion 13 restricts the pedestal portion 12 so as to be movable in the X direction (width direction) and the Y direction (depth direction) in the drawing. The movement direction regulated by the guide portion 13 is not limited to the X direction and the Y direction, and the pedestal portion 12 may be regulated to be movable in the Z direction (vertical direction).

  Moreover, the distance measuring apparatus 10 installs the sensor unit 11 so that the projection angle (the depression angle) of the laser beam can be changed as shown in FIG. In the present embodiment, the sensor unit 11 is installed so that laser light can be projected to a predetermined angle (Θ) in the Y direction. The changeable light projection angle of the sensor unit 11 is not limited to the Y direction, and may be installed so that light can be projected up to a predetermined angle (Θ) in the X direction. Such a change in the projection angle of the sensor unit 11 can be performed using an angle adjustment unit (not shown). Moreover, the sensor part 11 is good also as installing not only a light projection angle but the height from the base part 12 so that a change is possible. Such a change in the height of the sensor unit 11 can be performed using a known altitude adjusting unit (not shown).

  In addition, the change of the projection angle and height of the sensor unit 11 and the movement of the pedestal unit 12 can be performed manually or automatically based on the control of the arithmetic unit 30 (the control unit 31). Further, the projection angle and height of the sensor unit 11 and the position information (XY coordinates) of the pedestal unit 12 are output to the control unit 31 of the arithmetic unit 30 together with the distance information measured by the sensor unit 11.

As shown in FIG. 3, the human body model 20 is a human body model of a three-dimensional waist surface shape of an adult female. Here, in this embodiment, after the human body model 20 is made to wear an object to be worn, the distance to the wearing surface of the object to be worn is measured using laser light that has passed through the human body model 20. That is, the laser light of the sensor unit 11 is projected from the inside of the human body model 20 onto the wearing surface of the wearing article. Therefore, the human body model 20 is composed of a member that transmits the laser light of the sensor unit 11, and the upper part is opened and the inside is formed in a cavity.
In addition, about the member which permeate | transmits a laser beam, arbitrary members can be used, For example, the wire mesh of a predetermined | prescribed wire diameter and mesh size, and a transparent acrylic board can be used. However, when a transparent acrylic plate is used, the laser beam is refracted when it passes through the transparent acrylic plate, so it is more preferable to use a wire mesh. In the case of a network structure, the laser light is blocked by the line portion, but is less affected by refraction and a highly accurate shape can be obtained. Therefore, in this embodiment, the human body model 20 made of a stainless steel wire net having a wire diameter of 0.8 mm and a mesh size of 5.0 mm is used.

As described above, the human body model 20 having the three-dimensional waist surface shape is hollow, and therefore, the inner surface includes the crotch surface 201, the abdomen surface 202, and the buttocks surface 203. (FIG. 3C). At this time, the crotch surface 201 is a substantially horizontal plane, and the abdomen surface 202 and the buttocks surface 203 are side surfaces rising from the crotch surface 201 in a substantially vertical direction.
In the present embodiment, it is assumed that the human body model 20 is placed on the pedestal portion 12 so that the ventral side faces the front.

  Returning to FIG. 1, the arithmetic device 30 calculates a gap (amount of gap) between the human body model 20 and the wearable object based on the distance measured by the distance measuring device 10 and outputs it appropriately. Such a calculation device 30 can use a general computer including a control unit 31, a storage unit 32, an input unit and a display unit (not shown), and the like. The arithmetic device 30 may be provided in the distance measuring device 10 itself, or may be a separate device that is communicably connected to the distance measuring device 10.

The control unit 31 controls the entire gap amount measuring device 1 according to the program stored in the storage unit 32. For example, the control unit 31 calculates the gap between the human body model 20 and the wearing object based on the distance information and the projection angle output from the sensor unit 11 and the position information of the pedestal unit 12. That is, as shown in FIG. 4, the human body model 20 is calculated by calculating the difference between the distance L from the sensor unit 11 to the wearing surface 401 of the article 40 and the distance I from the sensor unit 11 to the human body model 20. And the gap between the item 40 and the wearable item 40 are calculated. More specifically, the control unit 31 measures the three-dimensional shape of the wearing surface 401 from the distance L, measures the three-dimensional shape of the human body model 20 from the distance I, and compares both the three-dimensional shapes, whereby the human body A gap between the model 20 and the wear 40 is calculated.
At this time, in the present embodiment, the distance L to the wearing surface 401 rather than the outer surface 402 of the wearing item 40 is measured by projecting the laser beam transmitted through the human body model 20 onto the wearing surface 401 of the wearing item 40. I am going to do that. Thereby, the clearance gap between the human body models 20 can be measured correctly irrespective of the kind of the wearing article 40.

  The distance I to the human body model 20 formed of a member that transmits laser light can be measured by any method, and may be stored in advance in the storage unit 32, for example. It is good also as measuring using the sensor part 11, after sticking the reflective sheet which reflects a laser beam to the model 20. FIG. At this time, it is preferable that the reflection sheet has a negligible thickness, and for example, a color adhesive tape can be used. The attached reflection sheet is peeled off when measuring the distance L to the wearing surface 401.

  Here, in this embodiment, as shown in FIG. 1, the sensor unit 11 is installed above the human body model 20, and laser light is projected from the opening of the human body model 20. Instead, depending on the shape and size of the sensor unit 11, it may be arranged inside the human body model 20.

  The storage unit 32 stores various programs executed by the control unit 31 and calculation results of the control unit 31.

[Measurement method of three-dimensional shape]
The configuration of the void amount measuring apparatus 1 according to the present invention has been described above. Then, with reference to FIG.5 and FIG.6, the measuring method of the three-dimensional shape of the wearing surface 401 of the human body model 20 or the wearing article 40 is demonstrated. In the following description, the measurement of the three-dimensional shape of the wearing surface 401 of the article 40 will be described as an example, but the measurement of the three-dimensional shape of the human body model 20 can also be performed by the same method.

First, a specific method for measuring the distance L to the wearing surface 401 of the wearing article 40 will be described with reference to FIG.
For the crotch surface 201 in a substantially horizontal plane, the distance L can be measured using the sensor unit 11 installed above by moving the pedestal unit 12 in the X direction and the Y direction. On the other hand, the abdomen surface 202 and the buttocks surface 203 rising from the crotch surface 201 cannot project laser light from the sensor unit 11 installed above, and move in the X direction and the Y direction. Only the distance L cannot be measured. Therefore, by changing the light projection angle of the sensor unit 11 by a predetermined angle in the Y direction, the abdomen surface 202 and the buttocks are moved by moving the pedestal unit 12 in the Y direction or moving the sensor unit 11 in the Z direction. The distance L to the surface 203 is measured (if necessary, the change in the X direction may be performed).

  The distance L measured by the sensor unit 11 is output to the control unit 31 of the arithmetic unit 30 together with the position information (X, Y) of the pedestal unit 12 and the altitude information (H) of the sensor unit 11, and the control unit 31 performs three-dimensional By converting to data, a three-dimensional shape is measured. That is, the control unit 31 measures the three-dimensional shape by converting the sensor coordinate system (X, Y, L) to the global coordinate system (x, y, z).

Conversion of the sensor coordinate system to the global coordinate system can be performed by FIG. 6 or the following equation.

  In the present embodiment, since the light projection angle of the sensor unit 11 can be changed in the Y direction, the sensor coordinate system X is used as the entire coordinate system x, but the light projection angle of the sensor unit 11 is set in the X direction. When the change is made possible, the conversion from the sensor coordinate system X to the global coordinate system x is performed using the projection angle Θ of the sensor unit 11 in the same manner as the conversion from the sensor coordinate system Y to the global coordinate system y.

[Measurement of void volume]
Then, the measurement result of the void amount by the void amount measuring apparatus 1 of the present invention is shown in FIG. In FIG. 7, when the human body model 20 is worn with the shorts to which the absorbent body (sanitary napkin) is fixed, the gap between the short body and the absorbent body (hereinafter simply referred to as “wear”) and the human body model 20. Is measuring. In FIG. 7, the difference in the vertical direction (Z direction) between the human body model 20 and the worn article is measured as the gap amount.

For the wire mesh portion of the human body model 20, the laser beam is blocked, so that the accurate void amount cannot be calculated. However, for the other portions (network portion), the surface shape of the human body model 20 and the wearable object From the shape of the wearing surface, the void amount distribution could be calculated as shown in FIG.
At this time, when attention is paid to the region where the absorber is in contact, the region on the abdominal side (abdominal surface 202 side) from the center of the absorber is in a close contact state with almost no gap, whereas the region on the back side (butt portion) On the surface 203 side), it was found that there was a remarkable gap of about 40 mm at the maximum mainly in the row.
Moreover, in a cross section parallel to the frontal plane (EE cross section), the state in which the gap between the end portions is larger than the central portion is measured as a result of the absorber being deformed into a convex shape by being sandwiched between the left and right thighs. (FIG. 7B).

  From the above, according to the void amount measuring apparatus 1 of the present invention, as in a worn article such as a sanitary napkin or a worn article such as a diaper or a worn article that cannot be ignored in thickness, It is possible to accurately measure the void amount of the worn article, which was difficult to measure by this method.

[Effect of void amount measuring device 1]
According to the void amount measuring apparatus 1 described above, the following effects can be obtained.

  (1) The void amount measuring device 1 includes a pedestal unit 12 on which the human body model 20 is placed and a sensor unit 11 that measures the distance to the measurement object by projecting laser light onto the measurement object. The distance measuring device 10 and a human body model 20 that is configured by a member that transmits the laser light of the sensor unit 11 and that has an opening at the top and is formed in a hollow shape, and the distance measured by the distance measuring device 10 The calculation device 30 is configured to measure a three-dimensional shape of the human body model 20 and to calculate a void amount between the wearable item worn on the human body model and the human body model by comparing with the three-dimensional shape of the human body model 20. . At this time, the sensor unit 11 measures the distance L to the wearing surface by projecting laser light from the inside of the human body model 20 to the wearing surface of the wearing object worn on the human body model 20, and the arithmetic unit. No. 30, the amount of voids was calculated by comparing the three-dimensional shape of the human body model 20 with the three-dimensional shape of the wearing surface of the worn article.

  As a result, the amount of voids can be calculated using the shape of the wearing surface of the wearing item, not the shape of the outer surface of the wearing item, and the amount of void between the body can be accurately measured regardless of the type of wearing item can do.

(2) At this time, the sensor unit 11 is installed above the pedestal unit 12, and projects a laser beam onto the wearing surface of the wearing article by projecting a laser beam from the opening of the human body model 20. did.
Thereby, even if it is a sensor of the shape and magnitude | size which cannot be installed in the cavity part of the human body model 20, the exact amount of space | gap can be measured.

(3) The human body model 20 is made of a stainless steel wire mesh having a predetermined wire diameter and mesh size.
As a result, an appropriate gap amount can be calculated for the mesh portion without considering the refraction of the laser beam by the member of the human body model 20.

(4) Further, the distance measuring device 10 includes an angle adjusting unit that can change a light projection angle (declining angle) of the laser beam by the sensor unit 11, and the arithmetic device 30 is provided on the inner surface of the human body model 20 (wearing object). Among them, the shape of the abdominal surface 202 and the buttocks surface 203 rising from the substantially crotch surface 201 in a substantially vertical direction is measured based on the distance measured by the sensor unit 11 and the light projection angle of the sensor unit 11. .
Thereby, the three-dimensional shape of the human body model 20 and the wearing surface of a wearable object can be measured appropriately, and an accurate void amount can be measured.

(5) Moreover, the void | hole amount measuring method of this invention uses the void | hole amount measuring apparatus 1 comprised in this way, and the human body model 20 is attached to the human body model 20 in the state which stuck the reflective sheet which reflects a laser beam. The void amount is calculated based on the step of measuring the distance, the step of measuring the distance to the wearing surface with the reflective sheet peeled off from the human model 20, and the distance to the human model 20 and the distance to the wearing surface. And the process.
Thereby, the distance and the shape of the human body model 20 formed of a member that transmits laser light can be measured using the laser light of the sensor unit 11, and as a result, an accurate gap amount can be measured.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.

  For example, in the above embodiment, the gap amount between the shorts to which the absorbent body (sanitary napkin) is fixed and the human body model 20 is measured, but the present invention is not limited to this, and the present invention is not limited to this. It can be applied to other wearable items that can be worn on.

  In FIG. 7, the difference in the vertical direction (Z direction) between the human body model 20 and the wearable object is measured as the gap amount. However, the gap amount is not limited to the difference in the vertical direction, and depends on the part to be measured. It can be set as appropriate.

  Next, the present invention will be described in more detail based on examples using the void amount measuring apparatus 1 of the present invention. In addition, this invention is not limited by these following examples.

  In the example, three types of sanitary napkins such as samples S1, S2, and S3, which will be described later, were attached to the shorts and then worn on the human body model 20, and the amount of gap between the human body model 20 was measured. Here, the shapes of the three types of sanitary napkins of the samples S1, S2, and S3 will be described with reference to FIG.

The three types of sanitary napkins 50 are sanitary napkins having a general shape of 21 cm in the longitudinal direction and 9 cm in the width direction. In the sanitary napkin 50, an absorbent body 501 and a reinforcing paper 502 are sandwiched between a surface material and a back sheet, and bonded with a hot melt adhesive. At this time, an embossing 503 is formed on the surface material by the absorber 501. The absorbent layer of the absorbent body 501 is a mixture of pulverized pulp and superabsorbent polymer (SAP), and is wrapped with a hydrophilic tissue paper (weight per unit area: 15 g / m ² ).

The surface material is a polyester, polyolefin-based 30 g / m ² through-air nonwoven fabric, and the back sheet is a 23 g / m ² polyethylene resin film. The side sheets 504 located on both sides of the surface material are nonwoven fabrics made of polypropylene fibers at 15 g / m ² , and the reinforcing paper 502 is 30 g / m ² .

In the sanitary napkin 50 having such a shape, in the samples S1, S2, and S3, the weight of the absorbent body 501 and the degree of pressure bonding of the absorbent body 501 are varied.
Specifically, the sample S1 has a basis weight of ground pulp of 100 g / m ² and a basis weight of SAP of 10 g / m ² , and the samples S2 and S3 have a basis weight of ground pulp of 300 g / m ² and a basis weight of SAP of 30 g / m ^2. (3 times the sample S1). In addition, the sample S3 presses the absorber 501 by applying a strong force about 2-3 times that of the sample S2.

  In the example, shorts to which such samples S1, S2, and S3 were fixed were worn on the human body model 20, and the amount of voids was measured. In the measurement, in addition to the difference in the degree of weighting and crimping, the difference in the amount of voids when the sanitary napkin swells due to menstrual blood is also measured, so that nothing is absorbed (dry state) and standard The void volume distribution was measured while absorbing 45 g of water corresponding to the amount of menstrual blood per day (absorption state).

[Effect of weight per unit]
In order to measure the influence of the basis weight on the void amount, the void amount of each of the dried samples S1 and S2 was measured, and a statistical test was performed. At this time, in order to examine the difference in the void amount in detail, the region where the sanitary napkin is attached is divided into 25 as shown in FIG. 9, the average void amount of each divided region is obtained, and a two-way analysis of variance is performed. Went.
FIG. 10A is a graph showing the measurement results of the void amount of samples S1 and S2. As a result of multiple comparisons, the distribution that the gap from the center to the ventral side of the sanitary napkin is small and the gap from the center to the hip side is large is a common feature regardless of the size of the basis weight, but the basis weight is large. In sample S2, there was a tendency for the voids to be relatively large compared to sample S1. More specifically, it was confirmed that sample S2 has a significantly larger amount of voids in regions 18 to 20 and regions 23 to 25 than sample S1.
From this, it was found that the effect of the fabric weight on the void formation mainly appears in the vicinity of the crack, and the void volume increases with the increase of the fabric weight in that region.

[Influence of crimping]
In order to measure the influence of the degree of pressure-bonding on the void amount, the void amount of each of the dried samples S2 and S3 was measured, and a statistical test was performed. At this time, in order to examine the difference in the void amount in detail, the region where the sanitary napkin is attached is divided into 25 as shown in FIG. 9, the average void amount of each divided region is obtained, and a two-way analysis of variance is performed. Went.
FIG. 10B is a graph showing the measurement results of the void amounts of the samples S2 and S3. As a result of multiple comparisons, the remarkable voids found around the cracks tend to be common regardless of the degree of crimping, but a difference in the amount of voids depending on the degree of crimping is observed from the center to the ventral side of the sanitary napkin. In addition, the sample S3 having strong pressure bonding tended to have a relatively small gap compared to the sample S2. More specifically, in regions 8, 9, 13, and 14, sample S2 has a larger gap than sample S3, and in regions 11 and 15, sample S3 has a larger gap than sample S2. Became.
Regions 8, 9, 13, and 14 are regions surrounded by front grooves mainly formed by pressure bonding, while regions 11 and 15 are regions outside the front grooves mainly near the thighs. From the results, it was found that in the region surrounded by the front groove, the air gap decreased as the pressure of the crimping increased, and in the region outside the front groove near the thigh, the air gap increased.

[Effect of presence or absence of absorption]
In order to measure the influence of the presence or absence of absorption on the void volume, the void volume of the samples S1, S2 and S3 in the dry state and the absorbed state was measured, and a statistical test was performed.
FIG. 10C is a graph showing the measurement results of the void amount in the dry state and the absorption state. As a result of the multiple comparison, in all the samples S1, S2, and S3, there was a tendency that the voids in the absorption state were relatively small as compared with the dry state.
In order to examine the difference in the void amount in detail, the region where the sanitary napkin is attached is divided into 25 as shown in FIG. 9, the average void amount of each divided region is obtained, and a two-way analysis of variance is performed. Although there was no significant difference in the presence or absence of absorption and the interaction between regions, there was a significant difference in the main effect regarding the presence or absence of absorption.
From this, it was found that the amount of voids decreased in the absorption state compared to the dry state regardless of the sanitary napkin region.
