Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to home electric appliances, OA (Of
fice Automation) When products such as equipment are discarded,
The present invention relates to a method for supporting collection and recycling of components and the like that require proper processing and contained in a product, and a support system using the method.

[0002]

2. Description of the Related Art When home appliances are no longer needed, most of them are crushed without any pretreatment such as decomposition, and only iron and some non-ferrous metals are recovered, and the rest is recovered by landfill. It is currently being disposed of. However, home appliances and other products also contain substances that have a negative impact on the environment when disposed of as they are, such as lead contained in electronic circuit boards and refrigerants such as refrigerators and air conditioners. If it is finally disposed of while it is contained in dust, it may cause environmental pollution due to elution into groundwater. In addition, the recycling rate of the product is low in the treatment by this method, and in particular, in the case of home electric appliances in which the proportion of metal is decreasing year by year, the recycling rate may decrease year by year.

[0003]

At present, the disposal of home electric appliances and the like is performed by local governments or processing companies. However, in the present specification, these parts and assemblies are referred to simply as "parts". "), Information on the proper processing and valuables contained in the product, ie," whether the components that make up the product contain substances that require proper processing, "or" the parts that make up the product contain rare metals. If information such as `` whether or not a valuable substance is contained, '' `` what is the name of the substance, if it is contained, '' or `` in which part is it contained? '' It becomes difficult to disassemble and collect materials that require proper processing and parts containing high-recovery-value materials, which hinders proper processing and also increases processing costs.

[0004] In order to solve the above-mentioned problems, the present invention surely collects parts containing substances requiring proper treatment at the time of product disposal, and further secures a target recycling rate. It is another object of the present invention to provide a recycling support method and a support system that present a disposal method capable of reducing a processing cost by efficiently collecting a component containing a material having a high recovery value.

[0005]

In order to achieve the above object, according to the present invention, there is provided a recycling support system for supporting a recycling process for disassembling a product having a plurality of components by outputting information on a component to be disassembled. And
A system is provided that includes a disposal method setting unit that determines a component to be disassembled, and a data output unit that outputs information on the component to be disassembled determined by the disposal method setting unit.

[0006] The disposal method setting unit of the present invention sets a predetermined high priority until the recycling rate of the product calculated to disassemble the parts to be disassembled becomes equal to or higher than the target recycling rate. Disassembly target addition means for sequentially adding components to the disassembly target is provided. Here, the product recycling rate is the mass ratio of the substance to be recovered to the entire product. The target recycling rate may be determined in advance, or may be determined by receiving an external input.

[0007] It is desirable that the priority be determined according to the recycling cost of each part. However, the recycling cost for each part means the cost of disposing of the part (that is, the cost required for disassembly and subsequent processing of the part; hereinafter, referred to as "disassembly cost"). It is a value obtained by subtracting the selling price of goods. With this configuration, the disposal method setting unit determines that the recycling rate of the product calculated to disassemble the part to be disassembled is equal to or higher than the target recycling rate,
In addition, the parts to be disassembled are determined such that the recycling cost of the product calculated to disassemble the parts to be disassembled is minimized. However,
The product recycling cost is a value obtained by subtracting the sum of the selling prices of the collected products obtained from the parts from the sum of the disassembly costs of all the parts to be disassembled. Also, the disassembly cost is the cost required for disassembly of parts and subsequent processing,
If necessary, the cost of only the decomposition may be used, or the cost of only the processing other than the decomposition may be used.

Further, according to the present invention, the decomposition target adding means includes:
Prioritize parts according to multiple criteria, determine disassembly candidates according to each priority,
Any of the decomposition target candidates may be selected according to a predetermined selection criterion.

In order to do this, the disassembly object adding means determines the priority order of the parts in accordance with a plurality of criteria, and the priority order determined in accordance with each of the priority criteria. From the parts with the highest rank, the parts to be disassembled are considered to be disassembled until the recycling rate of the product calculated to disassemble the parts to be disassembled is equal to or higher than the target recycling rate. Means may be provided that include a unit that is a decomposition candidate for each reference and a decomposition candidate selection unit that selects any one of the decomposition candidates and determines a part included in the selected decomposition candidate as a decomposition target. . The selection of the decomposition candidate can be performed, for example, so that the cost of recycling the product is minimized.

In addition, the parts to be disassembled are determined in accordance with the priority given based on one predetermined criterion, and the recycling rate calculated to disassemble the disassembled parts is determined by the target recycling rate. If the ratio has not been achieved, the process of determining the disassembly target component again based on another priority standard may be repeated until the target is achieved.

[0011] In the recycling support system of the present invention, the disposal method setting unit further includes priority disassembly target determination means for disassembling parts whose disassembly cost is equal to or less than the selling price of the recovered material among the parts constituting the product. It is desirable. Prior to the addition of the disassembly target by the disassembly target addition means described above, if parts for which the disassembly cost is equal to or less than the selling price of the recovered material are preferentially disassembled, the parts to be disassembled are also excluded from the disassembly target. Can be avoided.

Further, the present invention provides a recycling support method used in the above-described recycling support system of the present invention, and a storage medium holding a program for implementing the method.

The recycling support system according to the present invention includes a product information database for holding general information on products and parts constituting the products, information indicating one or more methods required for processing, A processing facility database that holds information such as the capacity of the processing equipment at the factory or the processing company (the amount that can be processed per unit time, the amount of material that can be recovered during processing, etc.), operating costs, etc., and when selling or disposing each substance It is desirable to have a substance price database that holds the prices of the materials. However, a means may be provided for receiving the input of such information required for the recycling support processing, and these databases may be omitted.

And a data output unit 14. The calculation unit 12 includes a disposal method setting unit 15. The disposal method setting unit 15 includes a priority decomposition target determination unit 15a and a decomposition target addition unit 15b.

The storage unit 11 is a storage area realized by the main storage device 21 and the auxiliary storage device 22. Also,
The remaining units 12 to 14 are stored in advance in the auxiliary storage device 22 or the external storage device 23, and are realized by the CPU 20 executing a program read into the main storage device 21.

In this embodiment, each unit is realized by executing software by a general-purpose computer as described above. However, the present invention is not limited to this, and hard-wired logic for executing each step described below is used. It may be realized by a hardware device including the hardware device or a combination of the hardware device and a general-purpose computer.

B. Next, an outline of a processing flow in the recycling support system 10 of the present embodiment will be described.

First, the calculation unit 12 receives an input of a target recycling rate via the input device 17 (step 101). However, this operation does not need to be performed every time, and may be omitted if the target recycling rate is stored in the storage unit 11 in advance. Also,
When using a value determined by law or the like, this input itself can be omitted by using a method of automatically acquiring information through a network. Here, as a method of automatically setting the target value through the network, for example, a method of connecting to a place where the legal value of the recycling rate is recorded through the Internet and extracting information therefrom can be considered. In this case, a network mechanism connected to the arithmetic unit 16 is required in addition to the configuration shown in FIG.

Next, the calculation unit 12 receives an input of a product type via the input device 17 (step 102).
The database search / read unit 13 reads the product information of the product indicated by the input model from the product information database 24 and stores it in the storage unit 11 (step 103).

Further, the calculation unit 12 determines information relating to necessary processing based on the read product information (step 104), and the database search / read unit 13 searches / reads the processing facility database 25. And stores the read data in the storage unit 11 (step 105).

Subsequently, the calculation unit 12 determines information on the required recovered substance based on the read product information and the processing equipment information (step 106), and the database search / read unit 13 uses the substance price database 26
Is searched and read, and the read data is stored in the storage unit 11 (step 107).

Next, using the data stored in the storage unit 11, the disposal method setting unit 15 included in the calculation unit 12 sets the disposal method (step 108).
To be stored. Subsequently, the calculation unit 12 calculates a recycling cost and a recycling rate according to the disposal method stored in the storage unit 11 (step 109), and records the result in the storage unit 11. These procedures (steps 108 and 109) are repeated until the optimal disposal method is selected (step 110). At the stage where the optimal disposal method is selected, the data output unit 14 outputs the selection result to the output device 18. (Step 111).

C. Data Structure (1) Product Information Database 24 The product information database 24 stores various information retrieved from the input model. In the present embodiment, as shown in FIG. A disassembly constraint database 42, a component parent / child information database 43, and a product model database 44 are provided.

Here, in the product type database 44, the first column has a product ID (identifier), the second column has a maker, the third column has a type, the fourth column has a year, the fifth column has a model, and the sixth column. , The total mass of the product is held. This database 4
Reference numeral 4 relates a product ID to model information of the product. In the present embodiment, the product model database 44 may be omitted as long as information on the mass of the product is stored in any of the storage areas.

The part information database 41 stores information on individual parts constituting a product. The first column has a product ID, the second column has a part ID, the third column has a name, and the fourth column has a disassembly method. , The fifth column holds the disassembly time, the sixth column holds the necessity of appropriate processing, and the seventh column holds a list of the collected products obtained by the disassembly. Based on this data, it is possible to determine the disassembly method, disassembly time, and necessity of appropriate treatment for each part constituting the product, and also to specify the collected material when disassembled.

The disassembly constraint database 42 stores information for specifying in advance a component requiring disassembly when disassembling a certain component.
Each column holds a restricted part ID.

The part parent / child information database 43 records the parent / child relationship of parts.
The child part ID is held in the column.

In the system 10 of the present embodiment, the three databases of the component information database 41, the disassembly constraint database 42, and the component parent-child information database 43 are used to determine the parent-child relationship between the product and the component when the product is disassembled. Since the branch and leaves are represented and managed in a tree shape having attributes, the calculation in the calculation unit 12 becomes easy.

The product information database 24 is desirably created by a maker who designed and manufactured the product, and provided to a processing plant / processing company. In addition, as a providing method, a method using a storage medium such as a CD-ROM, a method using a network such as the Internet, and the like can be considered.
In the former case, the drive for reading the storage medium is
In the case of the latter method, a device for providing a network function is required for each of the computing devices 16. Both databases need to incorporate a mechanism that can integrate those created by multiple manufacturers, or a mechanism that can search multiple databases created for each manufacturer using the manufacturer name etc. as a key, but these are the existing search systems It is possible to construct by using.

As shown in FIG. 4, the product information database 24 stores the parent-child relationship at the time of disassembly of the components constituting the product, the time required for disassembly of each component, and whether or not each component contains a proper processing substance. In addition, the amount of the collected substance obtained when decomposed and collected is stored.

By using the information stored in the product information database 24, the relationship between the components constituting the product can be represented in a tree-like component configuration diagram (FIG. 7). In FIG. 7, each rectangle 71 indicates a part constituting a product, and a line 72 connecting the rectangles 71 indicates a parent-child relationship. Of the two rectangles 70 connected by the line 72 indicating the parent-child relationship, the rectangle arranged on the top of the paper represents the parent,
The rectangle located below indicates the child.

In FIG. 7, the parts containing the proper processing material are represented by rectangles 73 each having a double line on each side. In addition, the relationship between a certain component and a constrained component that needs to be disassembled before disassembly is represented by adding an arrow 74 from the rectangle of the disassembly target component to the constrained component rectangle. Although not listed in the disassembly constraint database of this embodiment, when disassembling a child part, disassembly of the parent part is indispensable, and this is also a constraint.

The component configuration diagram shown in FIG. 7 shows that components 2 and 3 require proper processing and must be disassembled. Also, from the parts configuration diagram, in order to disassemble these parts 2 and parts 3 which must be disassembled, it is necessary to disassemble the part 1 which is a constraint, and there are no other parts which must be disassembled. You can see that.

(2) Processing Equipment Database 25 The processing equipment database 25 stores information on equipment owned by processing plants and processing companies. In this embodiment, as shown in FIG. Name, object in the second column, non-objects (objects that cannot be loaded) in the third column, processing capacity in the fourth column, operating costs in the fifth column, and collected items in the sixth column. .

The processing facility database 25 is created by each processing factory or processing company based on information on facilities and personnel used for its own processing work, and is provided in a state where it can be connected to the arithmetic unit 16. For example, it can be realized by providing it in an auxiliary storage device 22 such as a hard disk drive connected to the arithmetic device 16.

(3) Material Price Database 26 The material price database 26 stores the types of materials to be collected,
In this embodiment, the price (unit price) is stored for each quality. In the present embodiment, as shown in FIG. 6, the first column shows the substance name, the second column shows the quality of the substance, the third column shows the unit price, and the fourth column shows the unit price. The collection ratio is stored in a column.

The substance price database 26 is created by, for example, each processing plant / processing company using information in accordance with a contract with a company entrusted with sale / disposal, and can be connected to the arithmetic unit 16. provide. The providing method is the same as in the case of the processing facility database 25.

Further, as the material price database 26, it is also possible to use a material price which collectively manages and provides general market values. In this case, for example, a method in which a database is created based on information such as the transaction price of each substance published in a newspaper or the like and provided using a storage medium such as a floppy disk or a network can be considered. In this case, a drive for reading the storage medium and a device for providing a network function are required for the arithmetic unit 16.

In this embodiment, by providing the substance price database 26 not in the arithmetic unit 16 but in the external storage device 23, it is possible to cope with the price of the substance which fluctuates every day. For this reason, in the present embodiment, for example, when the price of a certain substance fluctuates, it is possible to flexibly change to a more efficient processing step in response thereto, and the operation of a processing plant or a processing company is more efficiently performed. It can be carried out.

The material price database 26 stores not only materials considered to be valuable materials such as iron and copper, but also information such as, for example, dust disposal costs that require disposal, and also stores information such as floppy (registered) data. (Trademark) For components that are reused as components, such as a disk drive, a hard disk drive, and a power supply device, various types of recycling processing can be performed by storing them as components.

D. Next, the flow of processing in the disposal method setting unit 15 will be described, taking as an example a case where the product 1 having the configuration shown in FIG. In the following processing, reference to information held in each database is performed by referring to information read from the database in steps 102 to 107 and stored in the storage unit 11.

(1) Setting of Disposal Method (Step 108) The disposal method setting section 15 determines the parts which must be disassembled based on the information held in the product information database 24,
Decompose. That is, the disposal method setting unit 15 determines, from the information on the necessity of proper processing (the sixth column) held in the parts information database 41, that the parts 1, 2, 3 need to be processed properly among the parts constituting the product 1. Is detected, the part 1 is detected as the restricted part of the parts 2 and 3 from the restricted part information held in the disassembly restriction database 42, and these parts are set as the parts to be disassembled.

(2) Calculation of Recycling Cost (Step 1)
Next, a method for obtaining the recycling cost will be described with reference to FIG.

First, the disposal method setting unit 15 determines a part to be disassembled (step 301). In the example shown in FIG. 7, among the parts constituting the product 1, the parts containing the appropriate processing substance are the parts 2 and 3 represented by the rectangle 73.
However, not only these, but also the part 1 which is a disassembly constraint of these parts 2 and 3 (that is, the part 1 located at the tip of the arrow 74 from the rectangle 73 representing these parts) is also
Be subject to decomposition.

Next, the disposal method setting unit 15 extracts the disassembly time required for the disassembly from the fifth column of the parts information database 41 in the product information database 24 for each of the disassembled parts (step 302). The sum of these values is calculated to determine the total value of the disassembly time (step 303), and the total value is multiplied by the unit price of the operator (cost per hour) to calculate the disassembly cost (step 304). Although the unit price of the worker is stored in the storage unit 11 in advance in the present embodiment, an input may be received via the input device 17. In this case, the value setting method can be the same as the normal application initial setting and option setting.

Next, the disposal method setting unit 15 calculates the cost required for processing the collected material obtained by disassembly. That is, the disposal method setting unit 15 sets the product information database 24
The collected material is extracted from the seventh column of the parts information database in the system (step 305), and the material price database 26 is further extracted.
It is determined which of the first and second columns corresponds to these collected items (step 306), and the unit price of each collected item is extracted from the third column (step 307).
05 and the amount of each recovered material extracted in step 307
The collected item price is calculated by multiplying the collected item unit price extracted in (Step 308).

Further, the disposal method setting unit 15 calculates the processing cost of the remaining parts that have not been subjected to disassembly. The remaining parts are a mixture of a plurality of materials, and the parts that require proper processing have been removed. Based on these conditions, the disposal method setting unit 15 detects that the “crusher” is appropriate by searching the second and third columns of the processing equipment database 25 (step 309), and performs the processing. The unit price is extracted from the fifth column, and the collected material after processing is extracted from the sixth column (step 310).

In parallel with this step 310, the disposal method setting unit 15 extracts the product total mass information held in the sixth column of the product type database 44 of the product information database 24 (step 311). The total value of the masses of the parts determined to be disassembled by 305 is obtained (step 312), and the difference between them is calculated as the mass of the parts not to be disassembled.

Then, the disposal method setting unit 15 calculates the processing cost by multiplying the mass by the processing unit price (step 31).
3) Also, using the collected material information for each material, the collected amount of each processed material is obtained (step 314), and the collected material is displayed in either the first column or the second column of the material price database 26. Is determined (step 31)
5) The unit price of each collected item is extracted from the third column (step 316), and the amount of each collected item calculated in step 314 is multiplied by the respective unit price of each collected item extracted in step 316 to obtain a value. The collection price is calculated by obtaining the total value (step 317). In this case, it is assumed that only the “crusher” is used. However, if it is necessary to feed into multiple processing facilities, the total value of the mass input into each facility and the operating cost of each facility What is necessary is just to sum up the processing costs of each facility and the prices of the collected materials, which are determined from the amount of the collected materials and the unit price of the collected materials.

The sum of the disassembly cost obtained in step 304, the processing cost obtained in step 313, and the collection price obtained in step 308 and step 317 (provided that the collection price assumes the profit obtained by selling positively). Therefore, the actual cost is the subtraction), which is the recycling cost in this case (step 318). Note that these steps do not necessarily need to be performed in the above-described order, and there is no problem even if the cost calculation processing is performed before or after.

(3) Calculation of Recycling Rate (Step 10)
Next, using the same example, a method of calculating the recycling rate will be described with reference to FIG. 9 (a part of step 109 in FIG. 3). Here, the recycling rate is a ratio of the mass to be recycled to the total mass of the product. The total mass of the product is stored in the sixth column of the product type database 44 of the product information database 24, read by the database search / read unit 13, and stored in the storage unit 11. If this data does not exist, the sum of the masses of the parts constituting the product may be used.

First, the disposal method setting unit 15 determines that the parts to be disassembled in FIG. 7 are the parts 2 and 3 that require proper processing, and the parts 1 and 2 that are disassembly restrictions of these parts 2 and 3. Is determined (step 501), and the collections of the individual parts to be disassembled are extracted from the seventh column of the parts information database in the product information database 24 (step 502). Is used to search the processing equipment database 25 (step 503), and the recoverable ratio is extracted (step 50).
4) The retrievable mass of the collected material to be processed is calculated by multiplying the amount of the collected material by the ratio (step 505).

In parallel with the processing of steps 503 to 505, the disposal method setting unit 15 searches the material price database 26 based on the collected material information (step 506) and extracts the recoverable ratio (step 507). ), By multiplying the amount and ratio of the collected material, the recoverable mass of the collected material to be treated as a substance is calculated (step 508).

Subsequently, the disposal method setting unit 15 calculates the recoverable amount of the remaining parts that were not subject to disassembly.
The remaining parts are a mixture of a plurality of materials, and the parts that require proper processing have been removed.
Based on these conditions, the disposal method setting unit 15 detects that the “crusher” is appropriate by searching the second and third columns of the processing facility database 25 (Step 509),
From the sixth column of the processing equipment database 25, the ratio of the collected material to the processing target is extracted (step 510).

In parallel with the processing of steps 509 to 510, the disposal method setting unit 15 obtains the total value of the mass of the parts determined to be disassembled up to step 502 (step 511) and is stored in the storage unit 11. The difference from the total mass of the product is set as the mass of the parts not to be disassembled (step 512). Then, the disposal method setting unit 15 calculates the collection amount for each material by multiplying the mass by the collection ratio, and sets the sum of the calculated amounts as the collection amount from the parts not to be disassembled (step 513). ). In this case, it is assumed that only the crusher is used.However, if it is necessary to put it into multiple treatment facilities, the total value of the mass input to each facility and the recovery rate of each facility What is necessary is just to sum up the obtained amount of recovery from each facility.

Next, the disposal method setting unit 15 determines the amount of recovery from the processing equipment obtained in step 505,
Of the recovered amount as a substance obtained in step 513 and step 513
The amount collected from the parts not subject to disassembly determined in (1) is summed up to obtain the total amount collected in this case (step 514), and this is divided by the total mass of the product stored in the storage unit 11 to obtain the recycling rate (step 515). ).

Note that these steps do not necessarily need to be performed in the order described above, and there is no problem even if the order of calculating the recoverable mass is changed.

(4) Determination of Optimal Method (Step 110) Next, based on the recycling cost and the recycling rate calculated by the above method, after achieving the target recycling rate, processing can be performed with a smaller recycling cost. The procedure for determining the method will be described with reference to FIG. According to this embodiment, the parts that must be disassembled for proper processing in the above-described steps (steps 108 and 109) are necessarily disassembled, and the recycling cost and the recycling rate are determined in advance. By starting the optimal method determination process (step 110) in a state in which the product is present, appropriate recycling process of the product is secured.

First, one of the parts not subjected to disassembly is set as a processing target, and the disassembly cost required for disassembling the part and the amount and price of the recovered material obtained thereby are calculated (step 401). . Here, the priority decomposition target determination means 15a of the disposal method setting unit 15 performs step 1
In the same way as the calculation method of recycling cost in 09,
Calculate the value when one part is disassembled.

Next, the priority disassembly object determining means 15a compares the disassembly cost with the cost of the recovered material (ie, the selling price of the recovered material) (step 402). In order to disassemble and collect, the recycle cost and the recycle rate of the entire product are recalculated, and the part ID of the part is stored in the storage unit 11 (step 403).

When the cost of the recovered material is lower than the cost of disassembly, the priority disassembly object determining means 15a sets the component I
D, the disassembly cost, the collection cost, and the collection amount are stored in the storage unit 11 (step 404).

The priority disassembly target determining means 15a repeats the above steps 401 to 404 for all the parts constituting the product which are not to be disassembled in step 109 (steps 405 and 406).

In general, because the collected material is expensive,
If there is a part whose recovery cost (recovery substance unit price × amount of recovered substance) exceeds the disassembly cost, disassembling this part,
Recycling rates increase and recycling costs go down. Therefore, it is a better recycling method to disassemble parts that meet this condition. Therefore, the disposal method setting unit 15 of this embodiment determines in advance the parts to be disassembled preferentially as disassembly targets by the processing of steps 401 to 406.

If the recycle rate exceeds the target recycle rate by the processing up to this point (step 40)
7), the disposal method setting unit 15 advances the processing to step 111, with the part determined as the object of disassembly at that time as the optimum object of disassembly.

At step 407, if the recycling rate is lower than the target recycling rate, it is necessary to further disassemble the parts. Therefore, the disposal method setting unit 15
Is the next decomposition target addition step (steps 404 to 4
According to 12), a part to be disassembled is added. The algorithm shown here is an example, and the present invention is not limited to this.

First, the disassembly target adding unit 15b of the disposal method setting unit 15 determines the amount of collection for each part and the recycling cost (difference between the cost of disassembly and the cost of collected material) stored in step 404, and The recycling cost is calculated, and parts are prioritized in ascending order of the numerical value (step 408). Here, the recycling cost per unit collection amount may be a value obtained by dividing the recycling cost by the collection amount, and the prioritization may be performed by rearranging the component data based on a normal sorting method.

Next, the disassembly target adding means 15b recalculates the recycling cost and the recycling rate when disassembling the part, assuming that the parts are disassembled in the descending order of the priority, and also sets the part ID of the part. Is stored in the storage unit 11 (step 409). The processing method in this step is the same as that in step 403 described above.

Subsequently, each time the recalculation is performed for each component, the disassembly target adding unit 15b determines whether the recycling rate is equal to or higher than the target recycling rate (step 41).
0) If the recycling rate is higher than the target recycling rate,
All the parts that have been decomposed up to that point are set as the optimum disassembly targets, and the processing is output as a disposal method (step 1).
Proceed to step 413 in 11).

On the other hand, if the calculated recycling rate does not reach the target recycling rate in step 410, the disassembly target adding means 15b determines that the processing target is not the last component (that is, the component with the lowest priority) ( (Step 411), for the component of the next priority (Step 41)
2) Similarly, the calculation of the recycling cost and the recycling rate, the storage of the part ID, and the comparison with the target recycling rate are repeated (steps 409 to 410).

If the object to be processed is the last part in step 411, the disposal method setting unit 15 sets all the parts to be disassembled so far as objects to be disassembled, and proceeds to the disposal method output processing (step 411). The process proceeds to step 414 of (111).

The optimum method determination process (step 11)
0) does not necessarily need to be executed as described above, and any actual algorithm may be used as long as a similar result is obtained. For example, the processing of steps 402 and 403 may be performed for each component after the repetition of steps 401, 404, 405, and 406. For reference, FIG. 18 shows a means for doing so.

In this case, as a priority decomposition target determination step, step 602 is used instead of steps 402 to 404.
To 606 may be executed. That is, the priority disassembly target determination unit 15a first calculates the disassembly cost, the collection cost, and the collection amount of the processing target component (Step 401), and then, as in Step 404, the component ID, the disassembly cost of the component, and the collection. The processing of storing the material cost and the collected material amount in the storage unit 11 (step 602) is performed in step 109.
Is repeated for all the parts not to be disassembled (steps 603 and 604). Next, the priority disassembly target determination unit 15a compares the calculated disassembly cost with the cost of the recovered material (step 605). Recycling costs for the entire product as in 403,
The recycle rate is recalculated and the parts I
D is stored in the storage unit 11 (step 606). In addition,
The processing of the remaining steps 401, 405 to 414 is the same as that described above.

(5) Output of disposal method (step 111) In step 407 or 410 in the above-described optimal method determination processing (step 110), if the calculated recycling rate is equal to or higher than the target recycling rate, the disposal method setting unit 15 Determines the part that has been determined to be disassembled at that time as the optimal disassembly target. Based on the determined disassembly target, the data output unit 14 outputs, on the display screen of the output device 18, the optimally disassembled parts and their relations as an optimal recycling method (step 41).
3). FIG. 11A shows an example of the display screen output here.

At step 413, the procedure of the processing (that is, the display of the parts to be disassembled and the hierarchy thereof), the recycling cost required for this processing, the recycling rate that can be realized by this processing, and the like are displayed.

Here, the data output unit 14 extracts a part to be disassembled based on the part ID stored in step 403 or step 409. For example, when the stored component IDs are "component 1,""component2,""component3," and "component 4," the data output unit 14 determines that these components are to be disassembled. Is displayed.

Here, the product information database 24
By using the parts parent-child information database 43 in combination, it is easy for an operator to understand the parts to be disassembled in a tree structure as in the example shown in FIG.

At the same time, the data output unit 14 also displays the recycling cost and the recycling rate obtained in step 409. Further, in the present embodiment, the user's convenience is achieved by additionally describing the target recycling rate input in step 101 or stored in the storage unit 11.

On the other hand, if it is determined in step 110 that the target recycling rate cannot be achieved even if the parts with the lowest priority are checked (step 411), the disposal method setting unit 15 sets the parts determined to be disassembled so far. Is determined as a decomposition target, and the process proceeds to step 414.

At step 414, the data output unit 1
4 is based on the determined disassembly target, and as a recommended recycling method, the parts targeted for disassembly and their relations,
Similar to step 413, the information is output to the display screen of the output device 18, and further information indicating that the target recycling rate cannot be achieved is output to the display screen (step 414). FIG. 11B shows an example of the display screen output here.

In this embodiment, as shown in FIG. 11B, by outputting a screen with a warning display 414a indicating that the target is not attained, it becomes clear whether or not the recycling rate has been achieved. is there. At this time, it is more convenient that the warning display 414a is highlighted so as to be conspicuous such as using red characters or blinking.

In the screen examples shown in FIGS. 11A and 11B, only the parts to be disassembled are shown, but the parts to be disassembled are disassembled. It is more convenient to show the order and the disassembly procedure when disassembling each part.

As a method for deriving the disassembly order, the order of the disassembly is generally the disassembly level (the parent is the highest among the component data in the order of parent, child, grandchild, grandchild,. ), The parts ID to be disassembled stored in steps 403 and 409 and the product information database 2
4, a method of setting the disassembly order such that parts having a higher disassembly level are prioritized can be used.

The disassembly procedure is performed in the product information database 2
4 may be displayed using the information held in the fourth column “disassembly method” of the component information database 41 included in the component information database 41. If a more detailed disassembly method is stored in the fourth column of the component information database 41, a more detailed disassembly procedure can be displayed. Thus, the output screen (disassembly work instruction screen) 21 in step 413 when the disassembly order 211 and the disassembly method 212 are displayed together.
0 is illustrated in FIG.

As shown in FIG. 22, the disassembly work instruction screen 210 is provided with a column 213 for checking the disassembly and a column 214 for inputting the reason why the disassembly was not performed.
The input to these columns 213 and 214 may be received via the input device 17. If you do this,
It is desirable that the operator input these pieces of information at the time of actual disassembly, because it is possible to confirm whether or not the work has been performed correctly.

Further, as exemplified in FIG. 23, a work result database 230 for storing the contents of the disassembly work instruction, the presence / absence of disassembly, and the reason for not disassembly is provided in the storage unit 11, as exemplified in FIG. In the calculation unit 12,
Means for storing the display contents of the disassembly work instruction display area 215, the input contents of the disassembly check input area 213, and the input contents of the non-disassembly reason input area 214 in the work result database 230; The information held in 230 is output to output device 18.
May be provided on the display screen. This is desirable because it is possible to confirm such information after the work and to confirm whether or not correct processing has been performed.

The work record database 230 shown in FIG. 23 has a work date and time in the first column, a work shop ID in the second column, a product ID in the third column, a target part ID in the fourth column, and a fifth part.
The disassembly operation content is stored in the column, the disassembly check content is stored in the sixth column, and the non-decomposition reason is stored in the seventh column. Regarding this database, if there is a check in the work check column, it means that the correct work was performed, and if there is no check, no decomposition was performed because of the non-decomposition reason stored in the seventh column. You will understand.

Further, in the parts information database 41 used in the present embodiment, the disassembly procedure for each part is expressed in a natural language. However, the disassembly procedure is more easily processed by an electronic computer and the data can be easily input. There is also a method of expressing the procedure by a symbol or the like. FIG. 24 shows an example of the data structure of the component information database 41 when this method is used.

In this example, in the fourth column of the component information database 41, instead of the data in the natural language, the first half 241 of the fourth column is a target component (if the component recorded in the third column is a target, In the second column 242 of the fourth column, the disassembly operation for the target component is recorded by a symbol or a code, respectively. At this time, in the first half of the fourth column, in addition to the expression method of the target component shown in the example, if the component exists in the product, the component ID of the component may be held.

In this case, if the storage unit 11 is further provided with an operation symbol decomposition method conversion database 250 as shown in FIG. 25, a decomposition method can be generated from the operation symbols in the parts information database. . Specifically, taking the back cover shown in FIG. 24 as an example, “six screws” are derived from the information stored in the first half of the fourth row.
Deriving “disassembly” and “moving (horizontally / horizontally / forward)” from the information stored in the second half of the fourth column, and combining these, disassembling “six screws of part 1 (back cover),
(To move horizontally, horizontally, or in front) ". Therefore, the data output unit 14
Work content information can be generated in this way and displayed on the disassembly work instruction screen 210.

If alphabets or simple symbols are used as operation symbols, input and management become easy. As an example of the operation symbol, a method described in JP-A-9-147023 or the like can be considered.

E. Effects of the present embodiment As described above, in the present embodiment, based on information on the disposal method of a product, the cost required for processing, and the amount of recyclable collection stored in advance as product information,
Along with supporting the realization of reliable processing of parts that require proper processing, we will propose a method that can achieve processing at a lower cost among methods that can achieve the target recycling rate. , Can support more efficient operation of the processing company.

<Embodiment 2> In Embodiment 1, the parts to be disassembled are determined in ascending order of the recycling cost per collected amount. In addition, for example, the parts containing rare metals and the mass of the parts are determined. It is also conceivable to perform a calculation in such a manner that decomposition is preferentially performed for a product having a high recovery price, a product having a high unit price of the collected material, a product having a high unit price of the collected material × a collected amount (collected material cost), or a product having a short decomposition time. In order to do this, instead of the prioritization (sorting process) based on the recycling cost per recovery amount in step 408 described above, prioritization is performed in such a way that the recovered material contains more rare metals, Prioritizing the parts in order of decreasing mass,
The priority may be set such that the unit price of the collected items becomes higher or the order of the collected items may become higher.

Further, the prioritization (sort processing) in step 408 is performed not only by one method but also by
As shown in FIG. 19, sorting is performed by a plurality of methods, and an optimum (method that achieves a target recycling rate and has the lowest recycling cost) disposal method is derived from the sorted methods. An exact optimal disposal method may be found.

In this case, steps 408 to 408
Instead of 413, parts are prioritized by sorting using a plurality of different criteria, and a disposal method (that is, a group of parts to be disposed) is determined based on the respective priorities. The disposal costs may be compared for each disposal method, and the disposal method output processing (step 111) may be performed for the lowest cost.

That is, in the example shown in FIG. 19, after executing steps 401 to 407, the disposal method setting unit 15 first gives priority to component data in accordance with the recycling cost per collection amount in the same manner as described above. After assigning the order (step 408), the disposal method is extracted according to the priority order (step 701), and the component data is prioritized using another criterion (mass in the example shown in FIG. 19). (Step 702), a disposal method is extracted according to the priority order (Step 703), and among the disposal methods extracted in Step 701 and Step 702, a method with the minimum recycling cost (Step 704) is output. Processing (step 111) is performed.

FIG. 26 shows details of the processing in steps 701 and 703. In these steps,
First, the disassembly target adding unit 15b of the disposal method setting unit 15 treats the component having the highest priority assigned in the immediately preceding step as a processing target, and recycles the recycling cost and the recycling rate in the same manner as in step 409 for the processing target component Is calculated and stored in the storage unit 11 together with the component ID (step 2601). Next, the decomposition target adding unit 15b
The calculated recycle rate is compared with the target recycle rate. If the target recycle rate has been achieved, the process proceeds to step 2605, and the recycle rate and the recycle cost are stored in the storage unit 11. On the other hand, if the target recycling rate has not been achieved, the component to be processed is not the last component (step 2603), and the component having the next highest priority is set as the processing target (step 2604), and the process returns to step 2601. If the processing target component is the last component in step 2603, the disassembly target addition unit 15b stores the calculated recycling cost and recycling rate in the storage unit 11 with all components as processing targets (step 2605). .

In this case as well, if the output of the disposal method in step 111 (step 705) cannot achieve the target recycling rate by the displayed method (ie, the group of parts to be processed), the same as in step 414, Is desirably displayed.

In the example shown here, two types of criteria for assigning priorities are used, but three or more types may be used. In this case, priorities are assigned (step 408,
702), and a disposal method is extracted (step 70).
The processing may be repeated for each reference.

<Embodiment 3> In this embodiment, information other than the product type (manufacturer, type,
Size, mass, etc.). That is, the recycling support system 120 of the present embodiment, as shown in FIG.
A product type database 27 is provided in the external storage device 23,
In the process of inputting and reading the product identification information in step 102 (shown in FIG. 3), not only the type of the product but also the input of the product type, maker, dimensions, mass, weight distribution, insufficient model, etc. are accepted. Based on the information held in the model database 27, an accurate model of the product can be derived from the input information. By providing such means, the system 120 of the present embodiment can be provided.
According to this, the product information database 24 can be used even when the exact model is not known.

According to the present embodiment, the product can be specified even when the model cannot be accurately input by the user, for example, when the seal indicating the model is peeled off and the model is unknown. The range of use is further expanded.

The configuration of each part and the flow of processing in this embodiment are stored in the external storage device 23 in the product type database 27.
This embodiment is the same as the first embodiment except that the first embodiment is provided and the processing in step 102 is different. Next, Example 1
Only the differences from the above will be described.

(1) Product Model Database 27 As shown in FIG. 13, the product model database 27 of this embodiment has a product ID in the first column, a model in the second column, a manufacturer name in the third column, and a fourth column. Year, type in the fifth column, dimension (width) in the sixth column, dimension (depth) in the seventh column, dimension (height) in the eighth column, mass in the ninth column, weight distribution in the tenth column (X direction),
The weight distribution (y direction) is held in the eleventh column in advance.

Similar to the product information database 24, the product type database 27 is created by the manufacturer who designed and manufactured the product, and is provided to the user of the system 120 of this embodiment, such as a processing factory or a processing company. Good. In addition, as a method of providing, CD-ROM (Compact Disc-Read Only
Memory) or a method using a network such as the Internet.
In the former case, a reading device for reading information from the storage medium may be provided in the arithmetic unit 16, and in the latter method, means for transmitting and receiving information to and from the network may be provided in the arithmetic unit 16. It is to be noted that a means for integrating a plurality of databases 24 and 27 created by a plurality of manufacturers is provided, or in the case where a plurality of databases 24 and 27 are provided for each manufacturer, these are input by a manufacturer name or the like. It is desirable to have a means for searching as.

In this embodiment, the product type database 27 is provided in the external storage device 23 independently of the product information database 24. However, without providing this database 27, the product type database of the product information database 24 can be used. 44 may be used for the same processing. In this case, the product model database 44
Is stored in the product model database 2 of this embodiment.
7, the product model database 44 may be referred to instead of referring to the product model database 27 in the processing of step 102 below.

(2) Product Identification Information Input / Read Processing (Step 102) Next, FIG. 14 shows the procedure of step 102 in this embodiment. The calculation unit 12 according to the present embodiment
First, an input receiving screen 150 shown in FIG. 15 is displayed on the display screen of the output device 18, and an input to any of the input fields is received via the input device 17 (step 200).

Note that the input receiving screen 150 in this embodiment includes a model input box 151, a maker name input box 152,
A type input field 153, dimension input fields 154 to 156, and a weight input field 157 are provided. Maker name input field 152
In the type entry field 153, information registered in the product information database 24 in advance is displayed as an option by pull-down. List display is also effective for model numbers, but since the number tends to increase, it is desirable to devise a method such as sorting alphabetically when displaying options. Concerning the dimensions, mass, weight distribution, and the like, it is convenient to use a dimension measuring device using image processing, a mass and weight distribution measuring device using a strain gauge, or the like, and to directly input the data from the measuring device.

When an input is made in at least one of the input fields 151 to 157 of the input screen 150, the calculation unit 12
Indicates that the input information is a model (step 20)
1) The entered model is searched in the product information database 24 (step 202). In this embodiment, in addition to items that completely match, for example, items that differ only by one character are detected. By performing a search by adding a condition other than a perfect match, more efficient processing can be performed. The search processing of the product information database 24 is performed via the database search / read unit 13.

As a result of the search based on the model, if the corresponding product is registered in the product information database 24 (step 203) and if it is specified as one (step 204), the calculation unit 12 checks Screen output device 18
Is input via the input device 17 to determine whether or not the type is correct (Step 214), and the process returns to Step 200 again. Accepts re-entry of search conditions.

When the correct information is input on the confirmation screen (step 214), the calculation unit 12 proceeds to step 202.
Is determined as the model of the product to be processed (step 219).

The confirmation screen displayed in step 214 is searched to show, for example, the external view of the product in addition to the manufacturer name, product type, model, year, dimensions, mass, characteristics, and the like. This is desirable because it makes it easier for the user to determine whether the product matches the actual product.

If no model has been input (step 201), or if there is no match (step 203) as a result of the search by model (step 202) even if the model has been input, If there is more than one and it cannot be specified (step 204), other search conditions (for example, manufacturer name, product type,
Based on the dimensions, mass, and weight distribution), the product model database 27 is searched to detect products that meet the conditions (steps 205 to 212).

That is, if there is a maker name input for all products registered in the product model database 27 as search targets (step 205), the calculation unit 12 searches for a record matching the maker name. Only the detected product records are searched (step 206). Further, the calculation unit 12 processes the maker name (step 2
05, 206), the type (step 20)
7, 208), dimensions and weight (steps 209, 21)
0) and weight distribution (steps 211 and 212) to narrow down products that match all the input data.

In addition, another item such as a manufacturing year can be used as a narrowing target. In this case, a process corresponding to the item to be added may be added between step 212 and step 213.

Here, the dimensions, mass, weight distribution, and the like of the product are not accurate numerical values, but are desirably searched within a range of, for example, ± 10% of the input numerical values.
This is because a measurement error or the like can be absorbed in this way.

Also, from step 205 to step 211
If the product model can be specified by this time, the process may directly proceed to step 213 without performing the subsequent narrowing-down process, thereby increasing the speed.

The above narrowing down process (steps 205 to 2)
12) When one candidate product (that is, a product that matches the input data) can be identified (step 21)
3), the calculation unit 12 advances the processing to step 214 described above.

In step 213, if there are two or more candidate products, the calculation unit 12 displays them in a list on the display screen of the output device 18 via the data output unit 14, and selects one of them. Accept (Step 2
16).

At step 216, if any of the listed products is selected (step 217), the process proceeds to step 219, where the selected model is set as the model of the product to be processed, and the process is terminated. On the other hand, if no product is selected in step 216,
2 returns the process to step 200.

<Fourth Embodiment> In the first embodiment, the information on the necessity of proper processing is held in the product information database 24. However, the recycling support system 160 of the present embodiment does not hold this information in advance. As shown in FIG. 16, the appropriate processing necessary material database 2 is stored in the external storage device 23.
8 and information on proper processing necessary items held therein,
Based on the material information held in the product information database 24, it is determined whether or not each part requires proper processing.

According to the system 160 of this embodiment, when a proper processing target is newly added due to, for example, a revision of the law, or when a processing target that has been conventionally a proper processing target is excluded from the target due to technological progress or the like. In addition, it is possible to apply the present invention to the standards that are different depending on the processing plant or the processing company only by rewriting the appropriate processing necessary material database 28, and to cope with the change of the appropriate processing target quickly and with a small effort. be able to.

The configuration of the recycling support system 160 according to the present embodiment includes the appropriate processing necessary database 28, the data structure of the product information database 24, and reads the appropriate processing required database 28 before step 108. Having a step, and step 1
Except for the procedure of the disposal method setting unit 15 in 08, the system is the same as the system 10 of the first embodiment. Therefore, only the differences from the first embodiment will be described here.

(1) Product Information Database 24 In the product information database 24 of the first embodiment, the information on the necessity of proper processing is held in the sixth column of the parts information database 41. In 24, the material used for the component is held in the sixth column of the component information database 41 in advance.

(2) Appropriate processing necessary article database 28 The data structure of the appropriate processing necessary article database 28 of this embodiment is shown in FIG. Appropriate processing necessary material database 28
Is a database that stores information used to determine substances that require proper processing. The first column lists the names of substances that require proper processing, and the second column lists the reasons why proper processing is required. Not) are pre-stored.

Further, the database retrieval / reading section 13 of this embodiment reads the appropriate processing necessary article database 28 before step 108 and stores the read data in the storage section 11. Next Step 10
The reference to the appropriate processing necessary material database 28 in FIG.
This is performed by referring to the information read into the storage unit 11.

(3) Disposal method setting processing (step 10)
8) The disposal method setting unit 15 sets the material indicated by the material information held in the sixth column of the part information database 41 of the product information database 24 in the appropriate processing It is determined whether or not the part requires proper processing based on whether or not it is registered. Note that, as in the first embodiment, a restricted part is detected from the restricted part information held in the disassembly restriction database 42 and is also subjected to decomposition.

<Fifth Embodiment> In the first embodiment, the method of disposing of a product is determined based on the information held in advance in the product information database 24. However, the recycling support system 270 of the fifth embodiment uses A database updating unit 271 is provided as means for receiving the input and registering the input information in the product information database, and determines a disposal method based on the input and registered information.

According to the system 270 of this embodiment, it is possible to carry out the recycling support processing for a product whose information is not registered in the product information database 24 in advance or a product whose registration is insufficient. In the present embodiment, the product information database 24 is provided in the external storage device 23. However, the present invention is not limited to this, the input product information is stored in the storage unit 11, and the product information database 24 is stored in step 102. Alternatively, the information input and stored in the storage unit 11 may be directly referred to instead of reading the information.

The configuration of the recycling support system 270 of this embodiment is the same as that of the system 10 of the first embodiment, except that the arithmetic unit 16 includes a database updating unit 13a as shown in FIG. However, in the system 270 of the present embodiment, unlike the case of the first embodiment, as shown in FIG. 28, between the steps 103 and 104, the design unit 12 sends all the product information necessary for the recycling support process. It is checked whether there is any information (step 2801), and if necessary information is insufficient, a product information obtaining process (step 2802) for obtaining the information is performed.

Therefore, here, only the product information acquisition processing which is different from the first embodiment will be described. If the product information database 24 is not provided, step 10
Step 2802 instead of 3,2801,802
, And the process of storing in the database in step 2802 may be omitted. In such a case, the database update unit 13a can be omitted.

(1) Example of Product Information Input Screen First, the product information input screen 200 displayed in the product information acquisition processing will be described with reference to FIG.

In this embodiment, the product information necessary for the recycling support processing includes a product ID, a product weight, a part ID,
Parts name, disassembly method, disassembly time, necessity information of proper processing,
The information includes collected item information, restricted part information, and parent-child relationship information of parts. In the present embodiment, the product information input screen 200 for receiving these inputs includes a display / edit area 200a for a product configuration and a display / input area 200b for a component attribute.

The product configuration display / edit area 200a is an area for displaying the product configuration (including the parent-child relationship between parts) in a tree shape and receiving an editing instruction.

On the other hand, the display / input area 200b of the component attribute
Includes a product ID display area 201 and a product weight input area 202, and an information input area 200c related to the component selected in the product configuration display / edit area 200a. The input area 200c includes input areas 203 to 209 for the part ID, the part name, the disassembly method, the disassembly time, the necessity information of the appropriate processing, the collection information, and the restricted part information of the selected part.

The configuration of the product information input screen 200 is as follows.
It is not necessarily the same as the present embodiment. For example, the parent component of the component is displayed in the component attribute display / input region 200b without displaying the constraint relation in a tree shape or providing the product configuration display / edit region 200a. An input of an ID may be received. Further, the information for accepting an input on the product information input screen 200 is not limited to the above-described example, and can be appropriately changed as needed.

(2) Product Information Acquisition Processing In step 2802, first, the calculation unit 12 displays the display screen of the output device 18 via the data output unit 14 as shown in FIG.
The product information input screen 200 shown in FIG.
The input to each of the input areas 200a, 202 to 209 is received via the.

Here, the calculation unit calculates the product I of the product to be processed.
D is displayed in the display area 201, and if the product information on the product is already registered in the product information database, the registered information is displayed in the corresponding input area in advance. In addition, each area 200a, 202 to 20
9 accepts CAD (Computer Assisted)
Design) system and the like.

When the input is performed, the calculation unit 12 stores the input information in a storage area (not shown) of the product information relating to the product, which is secured in the storage unit 11 in step 103.
In the product information database 24 via the database storage unit 13a.
