A method for manufacturing animal excrement disposal materials according to the present invention is now explained with reference to
(General Basic Embodiment)
A general basic embodiment of a method and a device for manufacturing animal excrement disposal materials according to the present invention is explained with reference to
(Animal Excrement Disposal Materials C100)
Therefore, the shape and materials of the animal excrement disposal materials C100 can be appropriately selected from those of known structures. For example, although the animal excrement disposal material C100 shown in
The animal excrement disposal material C100 is an example embodiment that corresponds to the “animal excrement disposal material” according to the present invention.
(First Manufacturing Device A1)
A manufacturing device A for animal excrement disposal materials performs a manufacturing method SA for animal excrement disposal materials according to this invention.
The manufacturing method SA and device A for animal excrement disposal materials are example embodiments that correspond to the “method for manufacturing animal excrement disposal materials” and the “device for manufacturing animal excrement disposal materials”, respectively, according to the present invention.
In the granulating part A100, granules are obtained from a raw material. A known step can be appropriately applied as the granulating step S100 in the manufacturing method for the animal excrement disposal materials C100. Specifically, in the granulating step S100, the raw material itself may be processed. In such a case, the granulating step S100 has a step of pulverizing the raw material, a step of kneading the pulverized raw material after adding liquid such as water, and a step of granulating into a prescribed shape. At this time, when using a preliminarily pulverized raw material, the step of pulverizing the raw material can be omitted.
The step of granulating the raw material into a prescribed shape may include a process of cutting the raw material extruded by an extruder into a prescribed length, a process of forming the raw material into a prescribed shape by a tableting machine and a process of forming the raw material into a prescribed shape within a rotating drum by rotation of the rotating drum.
Further, in the granulating step S100, when the main raw material is bentonite, granules can be formed by pulverizing bentonite ore, for example, with a Raymond mill and then chamfering.
A desired function may be imparted to the granules. In such a case, powder or liquid having the desired function is applied to the granules. The granulating step S100 includes such processing to which the granules formed into a prescribed shape are subjected.
The granulating part A100, the granulating step S100 and the granule are example embodiments that correspond to the “granulating part”, the “granulating step” and the “granule”, respectively, according to the present invention.
The granules obtained in the granulating part A100 are sorted in the sorting part A200 based on a prescribed size. A granule which is determined to have the prescribed size in the sorting step S200 of the sorting part 200A forms the animal excrement disposal material C100. In the sorting step S200, a sieve B100 which is described below is used to sort the granules based on the size. A granule which is determined not to be appropriate (in size) in the sorting step S200 is returned to the granulating step S100. The sorting part A200 and the sorting step S200 are example embodiments that correspond to the “sorting part” and the “sorting step”, respectively, according to the present invention.
Further, in the manufacturing device A and the manufacturing process SA according to the present invention, it is determined whether the sieve B100 is appropriate (for use) or not, and when determined to be inappropriate, the sieve B100 is replaced. The inappropriate sieve B100 includes the sieve B100 which is broken or clogged.
After passing through the sorting part A200, the animal excrement disposal materials C100 are transferred to a final processing part A800. In the final processing part A800, a final processing step S800 including all of processes following the sorting step S200 are performed. Specifically, the final processing step S800 includes a process of filling containers with the animal excrement disposal materials C100 and a process of packing a plurality of the containers filled with the animal excrement disposal materials C100 in each cardboard box for delivery. Further, the animal excrement disposal materials C100 passed through the sorting part A200 may be subjected to further processing. Such further processing is also included in the final processing step S800 according to this invention.
The sorting part A200 has a quality control part A300. In the quality control part A300, a quality control step S300 is performed to determine whether the sieve B100 in the sorting step S200 is appropriate or not.
The quality control part A300 has an extracting part A400, a comparison data calculating part A500 and a sieve replacing part A700. The extracting part A400, the comparison data calculating part A500 and the sieve replacing part A700 perform an extracting step S400, a comparison data calculating step S500 and a sieve replacing step S700, respectively. Further, equipment which is used in the extracting part A400, the comparison data calculating part A500 and the sieve replacing part A700 is referred to as quality control equipment.
The quality control part A300, the quality control step S300 and the quality control equipment are example embodiments that correspond to the “quality control part”, the “quality control step” and the “quality control equipment”, respectively, according to the present invention.
The extracting part A400 extracts a sample (not shown) to be measured from part of the animal excrement disposal materials C100 passed through the sorting part A200. The comparison data calculating part A500 calculates comparison data from a unit numerical value obtained by measuring the sample. In the sieve replacing part A700, the sieve B100 is replaced based on the comparison result.
Further, specific examples of the comparison data are described below in the first to 13th embodiment patterns with reference to
The extracting part A400, the comparison data calculating part A500, the sieve replacing part A700, the extracting step S400, the comparison data calculating step S500 and the sieve replacing step S700 are example embodiments that correspond to the “extracting part”, the “comparison data calculating part”, the “sieve replacing part”, the “extracting step”, the “comparison data calculating step” and the “sieve replacing step”, respectively, according to the present invention.
In the sieve replacing step S700, various kinds of operations for replacement of the sieve can be selected. For example, a display part may be provided to display the comparison data by characters, figures or symbols, or a sound generating part may be provided to transmit the comparison data by sound.
In this case, an operator can determine from the comparison data whether the sieve B100 of the sorting part A200 is appropriate or not. When the operator determines that the sieve B100 of the sorting part A200 is not appropriate, the operator can replace the sieve B100 with another sieve B100.
Thus, in the first manufacturing device A1, the sorting part A200 can be provided with the appropriate sieve B100. Therefore, the first manufacturing device A1 can provide the animal excrement disposal materials C100 having stable quality.
(Second Manufacturing Device A2)
The quality control part A300 may also be configured to automatically determine whether the sieve B100 of the sorting part A200 is appropriate or not.
An example of such a manufacturing device A is explained with reference to
The second manufacturing device A2 performs a second manufacturing method SA2. The comparison part A600, the reference data storage part A620 and the comparison operation part A610 perform a comparing step S600, a reference data storing step S620 and a comparison operation step S610, respectively.
The comparison part A600 is an example embodiment that corresponds to the “comparison part” according to the present invention.
In the reference data storage part A620 of the comparison part A600, reference date of a prescribed numerical value for determining whether the comparison data is appropriate or not is stored.
Further, examples of the reference data are described below in the first to 13th embodiment patterns with reference to
The comparison operation part A610 compares the comparison data and the reference data and determines whether the comparison data is appropriate or not.
When the comparison part A600 determines that the comparison data is appropriate, it means that the sieve B100 of the sorting part A200 is appropriate. Therefore, the quality control part A300 performs the quality control step S300 based on the next sample.
On the other hand, when the comparison part A600 determines that the comparison data is not appropriate, it means that the sieve B100 of the sorting part A200 is not appropriate.
In the sieve replacing part A700, the sieve B100 is replaced based on the information from the comparison part A600.
In the sieve replacing step A700 of the second manufacturing device A2, various kinds of operations for replacement of the sieve can be selected. For example, a display part may be provided to display the information indicating that “the sieve B100 of the sorting part A200 is not appropriate” by characters, figures or symbols, or a sound generating part may be provided to transmit the information indicating that “the sieve B100 of the sorting part A200 is not appropriate” by sound.
Further, as described below, based on the result of the comparison between the comparison data and the reference data, information indicating that “the sieve B100 of the sorting part A200 is to be replaced with a sieve B100 having a larger mesh size” or “the sieve B100 of the sorting part A200 is to be replaced with a sieve B100 having a smaller mesh size” may be transmitted.
Alternatively, a device for automatically replacing the sieve B100 of the sorting part A200 with another sieve B100 may be used.
Thus, in the second manufacturing device A2, the sorting part A200 can be provided with the appropriate sieve B100. Therefore, the second manufacturing device A2 can provide the animal excrement disposal materials C100 having stable quality.
(Comparison Data Calculating Part A500)
A specific structure of the comparison data calculating part A500 for obtaining the comparison data from the sample is explained with reference to
The comparison data calculating part A500 has a unit numerical value measuring part A510 that measures the sample with quality control equipment to obtain a unit numerical value of the sample, and a comparison data operation part A520 that obtains the comparison data based on the unit numerical value obtained from the unit numerical value measuring part A510. The comparison data calculating part A500, the unit numerical value measuring part A510 and the comparison data operation part A520 perform a comparison data calculating step S500, a unit numerical value measuring step S510 and a comparison data operation step S520, respectively.
In the present invention, the unit numerical value refers to a unit numerical value which can be obtained by the quality control equipment. The specific unit numerical value includes size (particle size) and weight. Further, examples of the comparison data which can be obtained by operating the unit numerical value include a surface area and a volume which are calculated from the size (particle size), a mass (weight) which is obtained from the volume and a specific gravity inputted by the operator, a surface area per unit weight which is obtained from the surface area and the weight, a volume per unit weight which is obtained from the volume and the weight, and standard deviations thereof.
An example of the comparison data calculating part A500 is explained with reference to
As the quality control equipment in the first unit numerical value measuring step S511, a device which is capable of measuring a desired unit numerical value is used. For example, when it is desired to obtain the particle size of the sample as a unit numerical value, a digital image analysis type particle size distribution measuring device FPA (manufactured by Nihon Rufuto Corporation) may be used. When it is desired to obtain the weight of the sample as a unit numerical value, a weigher may be used.
Other quality control equipment may also be used as the comparison data calculating part A500. For example, in
The second unit numerical value measuring part A512 uses a plurality of measuring sieves as the quality control equipment. The measuring sieves are different in mesh size. The measuring sieves are referred to as a first measuring sieve A5121, a second measuring sieve A5122, a third measuring sieve A5123 and an n-th measuring sieve A512n in descending order of the mesh size. Further, the number n of the measuring sieves (the value of n) is sufficient to be about ten, but it is preferable to provide a larger value of n (a larger number of sieves) for accurate calculation.
A plurality of samples are transferred from the extracting part A400 to the second unit numerical value measuring part A512. The samples are passed through the measuring sieves in order from one measuring sieve having a larger mesh size to another having a smaller mesh size and thus sorted by the size.
At this time, a sample left on the first measuring sieve A5121 having the largest mesh size is considered as having a particle size equal to the mesh size of the first measuring sieve A5121. Specifically, when the first measuring sieve A5121 has the mesh size of 2.8 mm, the particle size of the sample left on the first measuring sieve A5121 is taken as 2.8 mm.
In this manner, when no other measuring sieve having a larger mesh size than the measuring sieve (the current measuring sieve) on which the sample is left exists on the upstream side of the current measuring sieve, the mesh size of the current measuring sieve is taken as the particle size of the sample on the measuring sieve.
Next, the particle size of a sample left on the second measuring sieve A5122 is calculated. In this case, an average value of the mesh sizes of the first measuring sieve A5121 and the second measuring sieve A5122 is considered as the particle size of the sample. Specifically, when the mesh size of the second measuring sieve A5122 is 2.0 mm, and the mesh size of the first measuring sieve A5121 is 2.8 mm, the particle size of the sample left on the second measuring sieve A5122 is taken as 2.4 mm.
In this manner, when another measuring sieve having a larger mesh size than the current measuring sieve exists on the upstream side of the current measuring sieve, the average value of the mesh sizes of these measuring sieves is considered as the particle size of the sample. For another example, when the mesh size of the second measuring sieve A5122 is 2.0 mm, and the mesh size of the third measuring sieve A5123 is 1.7 mm, the particle size of a sample left on the third measuring sieve A5123 is taken as 1.85 mm which is an average value of the mesh sizes of the second measuring sieve A5122 and the third measuring sieve A5123.
Further, the particle size of a sample passed through the final n-th measuring sieve A512n is considered as being half the mesh size of the n-th measuring sieve A512n.
In this manner, a particle size of a sample can be obtained as the unit numerical value of the sample.
(Sieve Replacing part A700)
An outline of the sieve replacing part A700 is explained with reference to
The sieve B100, the current sieve B110 and the standby sieve B120 are example embodiments that correspond to the “sieve”, the “current sieve” and the “standby sieve”, respectively, according to the present invention.
As described above, the standby sieve B120 and the current sieve B110 are different in mesh size. The standby sieve B120 and the current sieve B110 “different in mesh size” here include those different in mesh size specification. Further, when broken or clogged, the current sieve B110 cannot function according to the specification. Therefore, in such a case, even if the current sieve B110 and the standby sieve B120 have the same mesh size specification, they are considered as having different mesh sizes.
(Third Manufacturing Device A3)
The manufacturing device A according to the present invention can improve the quality of the animal excrement disposal materials C100 by replacing the current sieve B110 with the standby sieve B120. Therefore, a new manufacturing process can be obtained by focusing on a specific effect of the manufacturing process A100 according to the present invention.
For example, user friendliness of the animal excrement disposal materials C100 may be improved by mixing the animal excrement disposal materials C100 having different unit numerical values.
Naturally, the aggregate of the animal excrement disposal materials C100 having different unit numerical values has to satisfy desired constant quality. This “constant quality” can be obtained, for example, by mixing the animal excrement disposal materials C100 satisfying one reference data with the animal excrement disposal materials C100 satisfying another reference data in a prescribed ratio.
Further, the animal excrement disposal materials C100 satisfying one reference data and the animal excrement disposal materials C100 satisfying another reference data may be formed of the same raw material or of different raw materials.
According to the present invention, the mesh size of the sieve B100 and the reference data of the animal excrement disposal materials C100 to be manufactured can be associated with each other. In other words, the animal excrement disposal materials C100 satisfying different reference data can be associated with the respective sieves B100 having different mesh sizes.
Methods for manufacturing the animal excrement disposal materials C100 by using a plurality of the current sieves B110 are described below with reference to
As the manufacturing device A for manufacturing animal excrement disposal materials according to the present invention, a third manufacturing device A3 is explained with reference to
The third manufacturing device A3 has a plurality of granulating parts A100, a plurality of sorting parts A200 and a plurality of quality control parts A300. The granulating parts A100, the sorting parts A200 and the quality control parts A300 are simultaneously operated.
Specifically, in
Granules which are formed in the first granulating part A101 are sorted in the first sorting part A201. A granule obtained in the first sorting part A201 forms a first animal excrement disposal material (not shown). The first quality control part A301 determines based on the first animal excrement disposal material whether the current sieve B110 in the first sorting part A201 is appropriate or not. In the present invention, the first granulating part A101, the first sorting part A201 and the first quality control part A301 are referred to as a first granule obtaining part AA. The first granule obtaining part AA performs a first granule obtaining step SAA.
Granules which are formed in the second granulating part A102 are sorted in the second sorting part A202. A granule obtained in the second sorting part A202 forms a second animal excrement disposal material (not shown). The second quality control part A302 determines based on the second animal excrement disposal material whether the current sieve B110 in the second sorting part A202 is appropriate or not. In the present invention, the second granulating part A102, the second sorting part A202 and the second quality control part A302 are referred to as a second granule obtaining part AB. The second granule obtaining part AB performs a second granule obtaining step SAB.
The current sieves B110 in the first and second sorting parts A201, A202 have different mesh sizes. The current sieve B110 in the first sorting part A201 and the current sieve B110 in the second sorting part A202 are defined as a first current sieve (not shown) and a second current sieve (not shown), respectively.
The first and second animal excrement disposal materials are transferred to the final processing part A800. The final processing part A800 has a mixing part A810 for mixing the first animal excrement disposal materials and the second animal excrement disposal materials in a prescribed ratio. The mixing part A810 performs a mixing step S810.
In this manner, a product in which the animal excrement disposal materials C100 satisfying different reference data are mixed together in a prescribed ratio can be provided with constant quality.
(Fourth Manufacturing Device A4)
As the manufacturing device A for manufacturing animal excrement disposal materials according to the present invention, a fourth manufacturing device A4 is explained with reference to
In the fourth manufacturing device A4, each of the granulating part A100, the sorting part A200 and the quality control part A300 is a single machine unit. Here, when the first current sieve is used in the sorting part A200, the granulating part A100, the sorting part A200 and the quality control part A300 form the above-described first granule obtaining part AA. Further, when the second current sieve is used in the sorting part A200, the granulating part A100, the sorting part A200 and the quality control part A300 form the above-described second granule obtaining part AB.
The first animal excrement disposal materials obtained in the first granule obtaining part AA are stored in a storing part A900. After prescribed first animal excrement disposal materials are manufactured, the first current sieve is replaced with the second current sieve, and accordingly, the first granule obtaining part AA is referred to as the second granule obtaining part AB. The second animal excrement disposal materials obtained in the second granule obtaining part AB are transferred to the final processing part A800 together with the first animal excrement disposal materials stored in the storing part A900. Then in the mixing part A810 of the final processing part A800, the first and second animal excrement disposal materials are mixed together in a prescribed ratio.
In this manner, a product in which the animal excrement disposal materials C100 having different comparison data are mixed together in a prescribed ratio can be provided with constant quality.
In the manufacturing method and device for animal excrement disposal materials as explained above in the general basic embodiment, the animal excrement disposal materials C100 having stable quality can be provided. In this case, the animal excrement disposal materials C100 “having stable quality” refer to those having more stable or uniform particle size. Specifically, according to the present invention, variation in the particle size of the animal excrement disposal materials C100 can be reduced, so that a standard deviation in a desired unit of measurement relating to the animal excrement disposal materials C100 can be reduced.
(Embodiment Patterns)
First to 14th embodiment patterns according to the present invention are explained with reference to
In the description of the first to fourth embodiments, structures and process steps identical to those in the above-described general basic embodiment are given like designations and numerals and they are not described herein.
The manufacturing method and device for animal excrement disposal materials according to the first embodiment of the present invention are explained with reference to
In the first embodiment, surface area per unit weight is used as the comparison data which is obtained in the comparison data calculating part A500. Therefore, the surface area per unit weight is also used as the reference data.
First, a step of obtaining the surface area per unit weight of samples as the comparison data in the comparison data calculating part A500 is explained. As described above, the unit numerical value of the animal excrement disposal materials C100 is obtained in the unit numerical value measuring part A510 of the comparison data calculating part A500. At this time, the “particle size” is obtained as the unit numerical value, and the number of the samples whose “particle size” has been measured is measured and stored.
In the comparison data operation part A520, a reference shape which is assumed as a prescribed shape is prepared having the shape of a sphere.
In the comparison data operation part A520, the “radius r of the sample” is obtained based on the particle size obtained in the comparison data calculating part A500. Then the radius r of the sample is assigned to the spherical reference shape, and the surface area of the sample is obtained based on the formula for calculating the surface area of a sphere (=4πr2).
Further, in the comparison data operation part A520, the volume of the sample is obtained. Specifically, the radius r of the sample is assigned to the spherical reference shape and the volume of the sample is obtained based on the formula for calculating the volume of a sphere (=4/3πr3).
Further, in the comparison data operation part A520, the weight (mass) of the sample is obtained from the volume of the sample. In this case, the specific gravity of the sample is inputted into the comparison data operation part A520. The weight of the sample is obtained by multiplying the volume of the sample by the specific gravity of the sample.
Further, in the comparison data operation part A520, the surface area of the sample is divided by the weight of the sample, so that the surface area per unit weight of the sample is obtained as the comparison data.
At this time, the comparison data is an average value of the surface areas per unit weight of a plurality of the samples. The “average value of the surface areas per unit weight of the samples” is referred to as “average sample surface area per unit weight”. Further, the comparison data may also be the surface area per unit weight of each sample. The “surface area per unit weight of each sample” is referred to as “individual sample surface area per unit weight”.
The surface area per unit weight used as the reference data is an arbitrarily prescribed numerical value. Therefore, the reference data may also be a surface area per unit weight which is obtained from the animal excrement disposal materials C100 by using the appropriate current sieve B100.
The reference data may or may not have a prescribed numerical range. The reference data “not having a numerical range” refers to a single fixed value.
The reference data is inputted and stored in the reference data storage part A620 of the comparison part A600.
(First Embodiment Pattern)
The manufacturing method SA and device A for animal excrement disposal materials according to the first embodiment pattern are explained with reference to
In the manufacturing method SA and device A for animal excrement disposal materials according to the first embodiment pattern, a first comparison operation step S611 is performed in the comparison operation part A610 of the comparison part A600. In the first comparison operation step S611, first, as a first operation processing S6111, the average sample surface area per unit weight is inputted into the comparison operation part A610. Next, as a second operation processing S6112, the average sample surface area per unit weight is transmitted to the sieve replacing part A700. As a result, the operator can grasp the state of the current sieve B110 of the sorting part A200 from the comparison data. Further, when the operator determines from the comparison data that the current sieve B110 is not appropriate, the operator can replace the current sieve B110 with the standby sieve B120.
In this manner, in the manufacturing method SA and device A for animal excrement disposal materials according to the first embodiment pattern, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 based on the comparison data. Therefore, the animal excrement disposal materials C100 having stable quality can be manufactured.
(Second Embodiment Pattern)
The manufacturing method SA and device A for animal excrement disposal materials according to the second embodiment pattern are explained with reference to
In the manufacturing method SA and device A for animal excrement disposal materials according to the second embodiment pattern, a second comparison operation step S612 is performed in the comparison operation part A610 of the comparison part A600. In the second comparison operation step S612, first, as a first operation processing S6121, the average sample surface area per unit weight and the reference surface area per unit weight having a prescribed numerical range are inputted into the comparison operation part A610. Next, as a second operation processing S6122, it is determined whether or not the average sample surface area per unit weight falls within the prescribed numerical range of the reference surface area per unit weight. When it is determined in the second operation processing S6122 that the average sample surface area per unit weight falls within the prescribed numerical range of the reference surface area per unit weight, completion processing is performed. By the completion processing of the second operation processing S6122, the second comparison operation step S612 is reset and the first operation processing S6121 is performed based on the next average sample surface area per unit weight.
On the other hand, when it is determined in the second operation processing S6122 that the average sample surface area per unit weight does not fall within the prescribed numerical range of the reference surface area per unit weight, a third operation processing S6123 is performed.
In the third operation processing S6123, it is determined whether or not the average sample surface area per unit weight exceeds the upper limit of the prescribed numerical range of the reference surface area per unit weight.

The manufacturing method and device for animal excrement disposal materials according to the second embodiment of the present invention are explained with reference to
In the second embodiment, surface area is used as the comparison data which is obtained in the comparison data calculating part A500. Therefore, the surface area is also used as the reference data which is compared with the comparison data in the comparison part A600.
First, a step of obtaining the surface area of samples as the comparison data in the comparison data calculating part A500 is explained. As described above, the unit numerical value of the animal excrement disposal materials C100 is obtained in the unit numerical value measuring part A510 of the comparison data calculating part A500. At this time, the “particle size” is obtained as the unit numerical value, and the number of the samples whose “particle size” has been measured is measured and stored.
In the comparison data operation part A520, a reference shape which is assumed as a prescribed shape is prepared having the shape of a sphere.
In the comparison data operation part A520, the “radius r of the sample” is obtained based on the particle size obtained in the comparison data calculating part A500. Then the radius r of the sample is assigned to the spherical reference shape, and the surface area of the sample is obtained based on the formula for calculating the surface area of a sphere (=4πr2). In the present invention, this surface area based on the reference shape is defined as the surface area of the sample.
At this time, the comparison data is an average value of the surface areas of the samples. The “average value of the surface areas of the samples” is referred to as “average sample surface area per unit weight”. Further, the comparison data may also be a surface area of each sample. The “surface area of each sample” is referred to as “individual sample surface area”.
The surface area used as the reference data is an arbitrarily prescribed numerical value. Therefore, the reference data may also be a surface area which is obtained from the animal excrement disposal materials C100 by using the appropriate current sieve B100.
The reference data may or may not have a prescribed numerical range. The reference data “not having a numerical range” refers to a single fixed value.
The reference data is inputted and stored in the reference data storage part A620 of the comparison part A600.

Next, as a second operation processing S6162, the average sample surface area is transmitted to the sieve replacing part A700. As a result, the operator can grasp the state of the current sieve B110 of the sorting part A200 from the comparison data. Further, when the operator determines from the comparison data that the current sieve B110 is not appropriate, the operator can replace the current sieve B110 with the standby sieve B120.

When it is determined that the average sample surface area does not exceed the upper limit of the prescribed numerical range of the reference surface area, the average sample surface area is considered as being below the lower limit of the prescribed numerical range of the reference surface area. This means that the surface area of the animal excrement disposal materials C100 is smaller than the desired surface area.
In this case, a fourth operation processing S6174 is subsequently performed. In the fourth operation processing S6174, it is indicated to the sieve replacing part A700 that the current sieve B110 needs to be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110.

The comparison data operation part A520 in the ninth embodiment pattern is defined as a ninth comparison data operation part A529. The reference data is stored in the reference data storage part 620 of the comparison part A600.
In the manufacturing method SA and device A for animal excrement disposal materials according to the ninth embodiment pattern, a ninth comparison operation step S619 is performed in the comparison operation part A610 of the comparison part A600. In the ninth comparison operation step S619, first, as a first operation processing S6191, the average sample surface area and the reference surface area having a prescribed fixed numerical value are inputted into the comparison operation part A610. Next, as a second operation processing S6192, it is determined whether or not the average sample surface area is equal to the fixed numerical value of the reference surface area. When it is determined in the second operation processing S6192 that the average sample surface area is equal to the fixed numerical value of the reference surface area, completion processing is performed. By the completion processing of the second operation processing S6192, the ninth comparison operation step S619 is reset and the first operation processing S6191 is performed based on the next average sample surface area.
On the other hand, when it is determined in the second operation processing S6192 that the average sample surface area is not equal to the fixed numerical value of the reference surface area, a third operation processing S6193 is performed.
In the third operation processing S6193, it is determined whether or not the average sample surface area exceeds the fixed numerical value of the reference surface area. When it is determined that the average sample surface area does not exceed the fixed numerical value of the reference surface area, the average sample surface area is considered as being smaller than the fixed numerical value of the reference surface area. This means that the surface area of the animal excrement disposal materials C100 is smaller than the desired surface area.
In this case, a fourth operation processing S6194 is subsequently performed. In the fourth operation processing S6194, it is indicated that the current sieve B110 of the sorting part A200 is to be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110 in the sieve replacing part A700.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110.
When it is determined in the third operation processing S6193 that the average sample surface area exceeds the fixed numerical value of the reference surface area, it means that the surface area of the animal excrement disposal materials C100 is larger than the desired surface area.
In this case, a fifth operation processing S6195 is subsequently performed. In the fifth operation processing S6195, it is indicated that the current sieve B110 of the sorting part A200 is to be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110 in the sieve replacing part A700.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110.
In this manner, in the manufacturing method SA and device A for animal excrement disposal materials according to the ninth embodiment pattern, the average sample surface area and the reference surface area having a fixed numerical value are used as the comparison data and the reference data, respectively. Thus, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having an appropriate mesh size. Therefore, the animal excrement disposal materials C100 having stable quality can be manufactured.
Further, in the third operation processing S6193, it is determined whether or not the average sample surface area exceeds the fixed numerical value of the reference surface area, but it may also be determined whether or not the average sample surface area is smaller than the fixed numerical value of the reference surface area.

The manufacturing method SA and device A for animal excrement disposal materials according to the 10th embodiment pattern are explained with reference to
The individual sample surface area is obtained in the comparison data operation part A520 of the comparison data calculating part A500. The comparison data operation part A520 in the 10th embodiment pattern is defined as a 10th comparison data operation part A52010. The reference data is stored in the reference data storage part 620 of the comparison part A600.
In the manufacturing method SA and device A for animal excrement disposal materials according to the 10th embodiment pattern, a 10th comparison operation step S61010 is performed in the comparison operation part A610 of the comparison part A600. In the 10th comparison operation step S61010, first, as a first operation processing S610101, the individual sample surface area and the fixed numerical value of the reference surface area are inputted into the comparison operation part A610. Next, as a second operation processing S610102, it is determined whether or not the individual sample surface area is equal to the fixed numerical value of the reference surface area. At this time, the number of the individual samples are measured and stored. Further, the number of the individual samples whose surface area is equal to the fixed numerical value of the reference surface area, the number of the individual samples whose surface area is larger than the fixed numerical value of the reference surface area, and the number of the individual samples whose surface area is smaller than the fixed numerical value of the reference surface area are measured and stored. Furthermore, the number of the individual samples whose surface area is equal to the fixed numerical value of the reference surface area and the number of the individual samples whose surface area is not equal to the fixed numerical value of the reference surface area are measured and stored.
Next, as a third operation processing S610103, it is determined whether or not the number of the individual samples whose surface area has been compared with the reference surface area reaches a prescribed number. When this number of the compared individual samples does not reach the prescribed number, the second operation processing S610102 is performed until the number of the compared individual samples reaches the prescribed number. When the number of the compared individual samples reaches the prescribed number, a fourth operation processing S610104 is performed.
In the fourth operation processing S610104, the number of the individual samples whose surface area is equal to the fixed numerical value of the reference surface is compared. When the number of the individual samples whose surface area is equal to the fixed numerical value of the reference surface area equals or exceeds a prescribed number, the current sieve B110 of the sorting part A200 is determined to be appropriate. In this case, completion processing is performed in the fourth operation processing S610104. By the completion processing of the fourth operation processing S610104, the 10th comparison operation step S61010 is reset and the first operation processing S610101 is performed based on the next average sample surface area.
On the other hand, when the number of the individual samples whose surface area is equal to the fixed numerical value of the reference surface area is smaller than the prescribed number in the fourth operation processing S610104, a fifth operation processing S610105 is performed.
In the fifth operation processing S610105, the number of the individual samples whose surface area is larger than the fixed numerical value of the reference surface area is compared with the number of the individual samples whose surface area is smaller than the fixed numerical value of the reference surface area. When the number of the individual samples whose surface area is larger than the fixed numerical value of the reference surface area is smaller, it means that the surface area of the animal excrement disposal materials C100 is smaller than the desired surface area.
In this case, a sixth operation processing S610106 is subsequently performed. In the sixth operation processing S610106, it is indicated that the current sieve B110 of the sorting part A200 is to be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110 in the sieve replacing part A700.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110.
When it is determined in the fifth operation processing S610105 that the number of the individual samples whose surface area is larger than the fixed numerical value of the reference surface area is smaller, it means that the surface area of the animal excrement disposal materials C100 is larger than the desired surface area.
In this case, a seventh operation processing S610107 is subsequently performed. In the seventh operation processing S610107, it is indicated that the current sieve B110 of the sorting part A200 is to be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110 in the sieve replacing part A700.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110.
In this manner, in the manufacturing method SA and device A for animal excrement disposal materials according to the 10th embodiment pattern, the individual sample surface area and the reference surface area having a fixed numerical value are used as the comparison data and the reference data, respectively. Thus, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having an appropriate mesh size. Therefore, the animal excrement disposal materials C100 having stable quality can be manufactured.
Further, in the 10th embodiment pattern, the determination is made based on the “number” of the measured individual samples, but it may also be made, for example, based on the “ratio” of the individual samples whose surface area is equal to the reference surface area, in all the measured individual samples, or the “ratio” of the individual samples whose surface area is larger than the reference surface area, to the individual samples whose surface area is smaller than the reference surface area.
The manufacturing method and device for animal excrement disposal materials according to the third embodiment of the present invention are explained with reference to
In the third embodiment, a standard deviation is used as the comparison data which is obtained in the comparison data calculating part A500.
First, a step of obtaining the standard deviation of samples as the comparison data in the comparison data calculating part A500 is explained. The standard deviation of the samples is obtained based on prescribed unit numerical values of the samples.
As described above, the unit numerical value of the animal excrement disposal materials C100 is obtained in the unit numerical value measuring part A510 of the comparison data calculating part A500. At this time, the “particle size” is obtained as the unit numerical value. Further, other different unit numerical values of the animal excrement disposal materials C100 can be obtained by operation of the comparison data operation part A520.
In the comparison data operation part A520, the number of the samples whose “particle size” has been measured in the unit numerical value measuring part A510 is measured and stored. Further, in the comparison data operation part A520, a reference shape which is assumed as a prescribed shape is prepared having the shape of a sphere.
In the comparison data operation part A520, the “radius r of the sample” is obtained based on the particle size obtained in the comparison data calculating part A500. Therefore, in the comparison data operation part A520, the “radius” can be obtained as the unit numerical value of the sample.
Further, in the comparison data operation part A520, the radius r of the sample is assigned to the spherical reference shape, and the surface area of the sample is obtained based on the formula for calculating the surface area of a sphere (=4πr2). Therefore, in the comparison data operation part A520, the “surface area” can be obtained as the unit numerical value of the sample.
Further, in the comparison data operation part A520, the volume of the sample can be obtained. Specifically, the radius r of the sample is assigned to the spherical reference shape and the volume of the sample is obtained based on the formula for calculating the volume of a sphere (=4/3′πr3). Therefore, in the comparison data operation part A520, the “volume” can be obtained as the unit numerical value of the sample.
Further, in the comparison data operation part A520, the weight (mass) of the sample is obtained from the volume of the sample. In this case, the specific gravity of the sample is inputted into the comparison data operation part A520. The weight of the sample is obtained by multiplying the volume of the sample by the specific gravity of the sample. Therefore, in the comparison data operation part A520, the “weight (mass)” can be obtained as the unit numerical value of the sample.
Further, in the comparison data operation part A520, the surface area of the sample can be divided by the weight of the sample, so that the surface area per unit weight of the sample is obtained. Therefore, in the comparison data operation part A520, the “surface area per unit weight” can be obtained as the unit numerical value of the sample.
Furthermore, in the comparison data operation part A520, the volume of the sample can be divided by the weight of the sample, so that the volume per unit weight of the sample is obtained. Therefore, in the comparison data operation part A520, the “volume per unit weight” can be obtained as the unit numerical value of the sample.
Specifically, as described above, in the comparison data calculating part A500, particle size, radius, surface area, volume, weight (mass), surface area per unit weight and volume per unit weight can be obtained as the “unit numerical value” of the sample. Further, the unit numerical value of the sample is referred to as a sample unit numerical value.
In the comparison data operation part A520, a standard deviation to be used as the comparison date is operated by obtaining a prescribed number of the sample unit numerical values.
When the standard deviation of the samples is operated from the prescribed unit numerical values of the samples, an average value of the prescribed unit numerical values can be obtained. The average value of the prescribed unit numerical values which is obtained by operating the standard deviation is referred to as an average sample unit numerical value.
In the comparison data calculating step, a value obtained by dividing the standard deviation by the average sample unit numerical value may also be used as the comparison data.
Further, the average sample unit numerical value may be used as part of the comparison data. In such a case, the standard deviation forms a first comparison data, and the “average value of the prescribed unit numerical values” forms a second comparison data.
The reference data is an arbitrarily prescribed numerical value for determining whether the comparison data is appropriate or not. The reference data has a prescribed numerical range. The reference data is inputted and stored in the reference data storage part A620 of the comparison part A600.
Further, when the comparison data has the first comparison data and the second comparison data, the reference data also has first reference data and second reference data. The first reference data is a prescribed numerical value for determining whether the first comparison data is appropriate or not. The second reference data is a prescribed numerical value for determining whether the second comparison data is appropriate or not.

In the manufacturing method SA and device A for animal excrement disposal materials according to the 11th embodiment pattern, an 11th comparison operation step S61011 is performed in the comparison operation part A610 of the comparison part A600. In the 11th comparison operation step S61011, first, as a first operation processing S6160111, the comparison data is inputted into the comparison operation part A610. Next, as a second operation processing S610112, the comparison data is transmitted to the sieve replacing part A700. As a result, the operator can grasp the state of the current sieve B110 of the sorting part A200 from the comparison data. Further, when the operator determines from the comparison data that the current sieve B110 is not appropriate, the operator can replace the current sieve B110 with the standby sieve B120.
In this manner, in the manufacturing method SA and device A for animal excrement disposal materials according to the 11th embodiment pattern, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 based on the comparison data.

In the 12th comparison operation step S61012, first, as a first operation processing S610121, the comparison data and the reference data having a prescribed numerical range are inputted into the comparison operation part A610. Next, as a second operation processing S610122, it is determined whether or not the comparison data falls within the prescribed numerical range of the reference data. When it is determined in the second operation processing S610122 that the comparison data falls within the prescribed numerical range of the reference data, completion processing is performed. By the completion processing of the second operation processing S610122, the 12th comparison operation step S61012 is reset and the first operation processing S610121 is performed based on the next comparison data.
On the other hand, when it is determined in the second operation processing S610122 that the comparison data does not fall within the prescribed numerical range of the reference data, a third operation processing S610123 is performed. In the third operation processing S610123, it is indicated to the sieve replacing part A700 that the current sieve B110 needs to be replaced with the standby sieve B120.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120.
In this manner, in the manufacturing method SA and device A for animal excrement disposal materials according to the 12th embodiment pattern, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 based on the comparison data. Therefore, the animal excrement disposal materials C100 having stable quality can be manufactured.

Further, the first reference data and the second reference data are used as the reference data. In this case, the first reference data is numerical data having a prescribed numerical range for determining whether the first comparison data is appropriate or not, and the second reference data is numerical data having a single numerical value (not having a numerical range) for determining whether the second comparison data is appropriate or not.
The first comparison data and the second comparison data are obtained in the comparison data operation part A520 of the comparison data calculating part A500. The comparison data operation part A520 in the 13th embodiment pattern is defined as a 13th comparison data operation part A52013. The reference data is stored in the reference data storage part A620 of the comparison part A600.
In the manufacturing method SA and device A for animal excrement disposal materials according to the 13th embodiment pattern, a 13th comparison operation step S61013 is performed in the comparison operation part A610 of the comparison part A600. In the 13th comparison operation step S61013, first, as a first operation processing S610131, the first comparison data, the second comparison data, the first reference data and the second reference data are inputted into the comparison operation part A610. Next, as a second operation processing S610132, it is determined whether or not the first comparison data falls within the numerical range of the first reference data. When it is determined in the second operation processing S610132 that the first comparison data falls within the numerical range of the first reference data, completion processing is performed. By the completion processing of the second operation processing S610132, the 13th comparison operation step S61013 is reset and the next first operation processing S610131 is performed.
On the other hand, when it is determined in the second operation processing S610132 that the first comparison data does not fall within the numerical range of the first reference data, a third operation processing S610133 is performed.
In the third operation processing S610133, it is determined whether or not the second comparison data is larger than the second reference data. When it is determined that the second comparison data is smaller than the second reference data, it means that the size of the animal excrement disposal materials C100 is smaller than the desired size.
In this case, a fourth operation processing S610134 is subsequently performed. In the fourth operation processing S610134, it is indicated to the sieve replacing part A700 that the current sieve B110 needs to be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a larger mesh size than the current sieve B110.
When it is determined in the third operation processing S610133 that the second comparison data is larger than the second reference data, it means that the size of the animal excrement disposal materials C100 is larger than the desired size.
In this case, a fifth operation processing S610135 is subsequently performed. In the fifth operation processing S610135, it is indicated to the sieve replacing part A700 that the current sieve B110 needs to be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110.
As a result, in the sieve replacing part A700, the current sieve B110 of the sorting part A200 can be replaced with the standby sieve B120 having a smaller mesh size than the current sieve B110.

The structure of the quality control part A300 according to the above-described first to 13th embodiment patterns is appropriately applied to the first quality control part A301 and the second quality control part A302.
The mixing part 810 of the final processing part A800 has the mixture quality control part A303. The mixture quality control part A303 performs a mixture quality control step S303. The mixture quality control part A303 determines whether or not the mixture of the animal excrement disposal materials obtained in the sorting parts A200 is appropriate.

As shown in
A flow control part A830 is formed at a confluent part between the first and second passages A821, A822. The flow control part A830 performs a flow control step S830. The flow control part A830 adjusts the mixing ratio of the first animal excrement disposal materials and the second animal excrement disposal materials to be a ratio of other than one to one such that the ratio of the first animal excrement disposal materials is higher or lower than the ratio of the second animal excrement disposal materials.

The flow control part A830 can be formed by a plate-like member disposed at the confluent part between the first and second passages A821, A822. In this case, the flow control part A830 is configured to be capable of swinging, with a point facing the confluent passage A823 in the confluent part as a supporting point, in a direction toward the first passage A821 and a direction toward the second passage A822 as shown by arrow A831. Further, even when the flow control part A830 is moved to either position, the flow control part A830 does not completely block the first or second passage A821, A822.
When the flow control part A830 is moved toward the first passage 821, the first animal excrement disposal materials come in contact with the flow control part A830, so that the amount of the first animal excrement disposal materials passing through into the confluent passage A823 decreases. Therefore, in the confluent passage A823, the ratio of the first animal excrement disposal materials becomes smaller than the ratio of the second animal excrement disposal materials. Contrarily, when the flow control part A830 is moved toward the second passage A822, the second animal excrement disposal materials come in contact with the flow control part A830, so that the amount of the second animal excrement disposal materials passing through into the confluent passage A823 decreases. Therefore, in the confluent passage A823, the ratio of the first animal excrement disposal materials becomes larger than the second animal excrement disposal materials.
Further, as for the flow control part A830, any structure other than the above-described structure may also be selected.
The mixture quality control part A303 determines whether or not the mixture of the first and second animal excrement disposal materials is appropriate in the confluent passage A823 and accordingly adjusts the position of the flow control part A830. Specifically, the mixture quality control part A303 controls the flow rates of the first animal excrement disposal materials and the second animal excrement disposal materials.

Specifically, the flow control part adjusting part is provided to change the position of the flow control part A830, while the sieve replacing part A700 is provided to replace the current sieve with the standby sieve.
In the mixture quality control part having the above-described structure, the position of the flow control part A830 can be manually or automatically adjusted based on the result of measurement of the mixture of the first and second animal excrement disposal materials.
Therefore, the animal excrement disposal materials having stable quality can be manufactured.
