Description

  The present invention relates to an environmental load value calculation device, an environmental load value calculation method, and an environmental load value calculation program for calculating an environmental load value generated in a manufacturing process.

  In recent years, as social interest in global environmental issues has increased, not only the effects of production activities in factories on the environment but also considerations on reducing the environmental impact of the products themselves are required. In view of this point, a technique called life cycle assessment (LCA) has attracted attention. LCA is a technique for analyzing and evaluating the environmental load throughout the life of a product and conducting improvement activities to reduce the environmental load. The life cycle of a product starting from raw material collection to manufacturing, distribution, use, and disposal (or recycling) is grasped and evaluated by this LCA.

  LCA does not judge the quality of the product life cycle, but comprehensively evaluates the life of the product, and quantitatively evaluates the environmental impact such as the degree of air pollution, resource efficiency, and the amount of waste. It is characterized by providing a means to carry out improvement activities scientifically and rationally.

  In the life cycle of a product, the environmental impact in each process such as raw material collection, distribution, use, disposal, recycling, etc., other than the manufacturing process, depends on the product specifications, distribution channel, and recycling method unless the product itself is changed. Since there is no change, it is thought that the environmental load value such as energy used from the beginning to the end of use of the product does not change greatly, and because it is easy to evaluate, it is not easy to calculate the environmental load value with high accuracy. Easy.

  On the other hand, there are many difficult problems in calculating the environmental load value in the manufacturing process. For example, in recent years, in the manufacturing process of hardware products, one company does not assemble from the minimum unit of product configuration such as parts and substrates, but purchases ready-made units for each function such as power supply unit, drive unit, etc. to produce products It has become mainstream. In such a situation, it is very difficult to disassemble the purchased unit, identify the parts and members used inside, and calculate the environmental impact assessment of the product by integrating the basic unit of the minimum unit of the product configuration. It is a difficult task. Furthermore, even if the unit is disassembled in detail and the internal parts and components are specified, it is extremely difficult to accurately calculate the environmental load resulting from the power consumption during processing and assembly.

  Furthermore, in the manufacturing process, it is relatively easy to calculate the total resource consumption of the same product, for example, the resource consumption per day in the factory, but when it comes to the energy used per product, the calculation Since the work is complicated, it is not easy to separate and extract the environmental load value in each manufacturing process from the total resource consumption. Therefore, there is a demand for the development of an LCA that can accurately evaluate the environmental load value in each manufacturing process.

  In response to such a request, for example, the amount of energy input for each lot is accumulated, and the accumulated amount of energy is divided by the number of products manufactured in that time, thereby obtaining an average environmental load value per product. Has been proposed (for example, see Patent Document 1). Further, a method is disclosed in which the environmental load of each step in the manufacturing process is calculated, and thereby which step has a large environmental load is compared numerically (for example, see Patent Document 2). In addition, an environment in which the amount of input resources or input energy supplied to the target facility is sequentially acquired, and the environmental load value at any time of a product manufactured at the target facility is calculated based on the acquired input resource amount or input energy amount. A load value calculation method is disclosed (for example, see Patent Document 3).

In addition, as a method of calculating the environmental load value in the case of producing an integrated processed product by combining a plurality of processing objects, for example, in order to measure the environmental load in the manufacturing process of a product that passes through a plurality of steps , Measuring means for measuring an environmental load when a manufacturing facility for performing each process performs the process on a part for constituting the product, and an environment attached to the part and measured by the measuring means An environmental load measurement system including a recording device that records load data and a measurement data transmission unit that transmits environmental load data from the measurement unit to the recording device is disclosed (for example, see Patent Document 4). .
Japanese Patent Application Laid-Open No. 08-235245 (first page to third page, FIG. 5) JP 2001-142528 A (page 1 to page 5, FIG. 1) JP-A-2004-246652 (first page to fourth page, FIG. 11) JP-A-2005-316703 (first page to third page, FIG. 1)

  However, since the method disclosed in Patent Document 1 obtains the environmental load value per product as an average value, the change is reflected when the production speed or the input energy amount changes in the same lot. Detailed history is unlikely to appear in environmental load values.

  Further, in the method disclosed in Patent Document 2, as described in paragraph [0038], the actual power consumption of the manufacturing facility alone is not obtained, but the rating of each manufacturing facility in the factory is determined. Since the average value is obtained from electric power, operating time, full power, etc., it is difficult to obtain an environmental load value reflecting a change in electric power over time.

  Further, in the method disclosed in Patent Document 3, it is possible to grasp the environmental load value corresponding to the input resource amount or the input energy amount supplied to the target equipment, but in the manufacturing process, other than the input resource amount and the input energy amount. In some cases, there are factors that increase the environmental load value, and this method cannot accurately grasp the environmental load value.

  As described above, in the conventionally proposed method, the calculation accuracy of the amount of increase in the environmental load value due to the energy, resources, and parts that are input when the processing object such as a unit product or product is processed by the manufacturing facility is high. Since the calculated value is low, the calculated value cannot be used as a management index for reducing the environmental load, and therefore effective environmental protection measures cannot be formulated.

  On the other hand, in Patent Document 4, when two or more parts are processed and assembled into one part, it is inefficient to attach a plurality of recording devices to a new part. In addition, it is described that it is preferable to aggregate the data of the recording apparatus attached to the original other parts into the recording apparatus attached to the original arbitrary part. It should be noted that it is only described that the storage device in which the data is aggregated may be appropriately selected, and there is no clear description.

  Further, Patent Document 4 describes that a product obtained by repeating such processing steps is accompanied by one recording device.

  However, it is unclear how the recording device attached to a plurality of parts before assembly is made only by the description of attaching one recording device to the product. For example, if the recording device attached to a part before assembly is attached without being removed, the data of a plurality of recording devices is double counted when the environmental load value of the product is read in the subsequent process. Or data that needs to be read out may be missed.

  In view of the above circumstances, the present invention provides an environmental load value calculation device, an environmental load value calculation method, and an environmental load value calculation program capable of accurately calculating and recording an environmental load value generated by processing a workpiece.

  As shown in FIG. 8, when the manufacturing process of the unit product 1 is started after the power of the manufacturing apparatus 100 provided with the environmental load calculation apparatus 10 (see FIG. 1) is turned on, the environmental load calculation apparatus 10 Data for starting production is transmitted to the wireless IC tag 3 (step S11). The wireless IC tag 3 that has received the production start data transmits the environmental load value recorded therein to the environmental load calculation device 10. The environmental load calculation device 10 waits for reception of the environmental load value (step S12), acquires time data at the time of reception, and sets it as a manufacturing start time (step S13).

  Next, when the user gives an instruction to the environmental load calculation device 10 from the keyboard 101 (see FIG. 4), current values and voltage value data during the manufacture of the unit product 1 are provided in the manufacturing device 100. The obtained power meter 17_1 (see FIG. 1) is fetched in real time through the interface 108 with a period of about 1 minute to 10 minutes, for example (step S14).

  Next, the production power is calculated from the production time M and the current value / voltage value data acquired from the power meter 17_1 (step S17).

  Next, the material consumption required for manufacturing the unit product 1 recorded in the material consumption database 15 (see FIG. 2) is read (step S18).

  Next, the input amount of energy, resources, and parts required for manufacturing the unit product 2 in the manufacturing apparatus 100 is converted into the environmental load value from the manufactured power and the material consumption amount, and the environmental load value thus obtained is calculated. And the environmental load value before processing (see step S12) received from the wireless IC tag 3 is added to obtain a processed environmental load value (step S19), which is transmitted to the wireless IC tag 3 (step S20). ).

  Here, it is determined whether or not there is a next process (step S21). If there is a next process, the process returns to step S11 to repeat the processes in and after step S11, and if there is no next process. End the process.

  Next, points to be noted in actual environmental load calculation will be described in detail.

  The environmental load calculation apparatus of this embodiment can be applied to a plurality of processes by a plurality of manufacturing apparatuses as shown in FIG. 3, but the manufacturing apparatus used for each of those processes is shown in FIG. A plurality of energy, resources, and parts are input. It is desirable to evaluate the environmental load value by extracting the inputs of all of these multiple energy, resources, and parts. However, if there are too many energy, resources, and parts to be evaluated, the environmental load can be efficiently It becomes difficult to evaluate the value. Therefore, it is preferable to evaluate the environmental load value by extracting about 99% or less of all the energy, resources and parts. Moreover, since evaluation will become coarse if there are too few evaluation objects, it is preferable to make 80% or more of the total number of evaluation objects.

  If the calculation result of the environmental load value does not require such high accuracy, the production time is obtained for each production management unit such as a lot without obtaining the production speed for each unit product. May be.

  In the environmental load calculation apparatus of this embodiment, the environmental load value A1 due to energy and resource consumption per product produced in a manufacturing apparatus at a certain time t can be obtained by the following equation.

Environmental load value A1 = (Da × M) × Eb + (Db × M) × Wb + (Dc × M) × Ob + (Dd × M) × Gb (1)
Here, Da to Dd are measured values output from the power meter 17_1, the tap water meter 17_2, the oil meter 17_3, and the city gas meter 17_4 shown in FIG. 4, and M is calculated in the steps of FIG. Eb, Ob, Wb, and Gb are environmental load values per unit amount of each input energy and input resource, and are specifically as follows.

Eb: Mass of CO ₂ discharged when producing 1 kw of electric power (kg-CO ₂ / kw)
Wb: Mass of CO ₂ discharged when producing 1 liter of water (kg-CO ₂ / liter)
Ob ... The mass of CO ₂ emitted when 1 liter of oil is consumed (kg-CO ₂ / liter)
Gb: Mass of CO ₂ emitted when 1 m ³ of city gas is consumed (kg-CO ₂ / m ³ )
Further, the environmental load value A2 due to the use of parts per product produced in a certain manufacturing apparatus can be obtained by the following equation.

Environmental load value A2 = Ba × Ka + Bb × Kb +... + Bn × Kn (2)
Here, Ba to Bn are used amounts of parts (see FIG. 2) to be input to the unit product, and Ka to Kn are environmental load values per unit input amount of each component, Specifically, it is as shown in FIG.

  As each environmental load value, for example, a known value reported by the Federation of Electric Power Companies is used.

  The total value of the environmental load values obtained by the equations (1) and (2) is displayed on the display 103 (see FIG. 4), evaluated by the user, and wirelessly transmitted by the environmental load data transmission means 109 after the manufacture is completed. The data is transmitted to the IC tag 3 and recorded in the data recording unit 33 (see FIG. 6) of the wireless IC tag 3.

In this way, the amount of CO ₂ as the environmental load value per unit product at an arbitrary time t can be easily obtained from the equations (1) and (2).

  In addition, in the present embodiment, the measured values Da to Dd of the input energy and the input resource amount are sequentially acquired, so it is possible to calculate the environmental load value in real time, and the change in the input energy amount and the input resource amount. The accompanying change in the environmental load value can be grasped with higher accuracy than before.

  Furthermore, according to the equation (1), since the environmental load value is calculated also using the production speed M of the product, the environmental load value A reflecting the time change of the production time M can be obtained.

  The amount of input energy, the amount of input resources, and the manufacturing speed described above constantly fluctuate while the manufacturing facility is operating, and the amount of change is large. It will reflect the actual environmental impact of each product faithfully, and can be used as a management index for reducing environmental impact.

In addition, although the example of the CO ₂ emission amount as the environmental load value has been described above, the NO _x and SO _x emission amounts may be used as the environmental load value.

When using the NO _x as environmental load value, (1) the Eb, Wb, Ob, following En instead Gb, Wn, On, may be used Gn value.

Here, En is the mass of the NO _x discharged in producing power _{1kw (kg-NO x / kw} ), Wn is the weight of NOx discharged in producing 1 liter of water (Kg-NO _x / liter), On is the mass of NO _x (kg-NO _x / liter) discharged when 1 liter of oil is consumed, and Gn is 1 m ³ of city gas. This is the mass of NO _x discharged when consumed (kg-NO _x / m ³ ).

When using SOx as an environmental load value, the following Es, Ws, Os, and Gs values may be used instead of Eb, Wb, Ob, and Gb in the equation (1).
Here, Es is the mass of SOx discharged when producing 1 kW of electric power (kg-SO _x / kw), and Ws is the mass of SOx discharged when producing 1 liter of water (kg -SO _x / liter), Os is the mass of SO _x discharged when consuming 1 liter of oil (kg-NO _x / liter), and Gs consumes 1 m ³ of city gas. it is the mass of the discharged the _{SO x (kg-SO x /} m 3) upon.

Below, the example of calculation of the environmental load value by the environmental load value calculation apparatus of this invention is demonstrated. In each of the following examples, among the three manufacturing apparatuses 100a to 100c, in the manufacturing apparatus 100a, screws: 5 pieces, resin A: 0.05Kg, resin B: 0.03Kg are added to the unit product: AAA100 shown in FIG. In the assembly and subsequent manufacturing apparatuses 100b and 100c, an example of calculating an environmental load value when predetermined processing is performed on each of the unit products after assembling the components will be described.
Example 1
In the manufacturing apparatus 100a, since the above three types of parts are assembled, the environmental load value A2 due to the input of these parts was calculated as follows.

Screw: 5 pieces × 0.002 kg-CO ₂ = 0.01 kg-CO ₂
Resin A: 0.05 kg × 2.5 kg-CO ₂ = 0.125 kg-CO ₂
Resin B: 0.03 Kg × 3.5 kg-CO ₂ = 0.105 kg-CO ₂
Total parts: 0.24 kg-CO ₂
Regarding power, the power of each manufacturing apparatus at time t when sufficient time had elapsed since the start of operation of the three manufacturing apparatuses 100a to 100c was as follows.

Manufacturing apparatus 100a: 10 kW
Manufacturing apparatus 100b: 5 kW
Manufacturing apparatus 100c: 15 kW
Further, in any of the manufacturing apparatuses 100a to 100c, the manufacturing time at time t was 0.1 hour.

The CO ₂ emission amount was calculated as the environmental load value per unit product. The input energy was only electric power, and Eb, which is the basic unit of electric power, was 0.37 (kg-CO ₂ / kw). This value is the 2000 national average reported by the Federation of Electric Power Companies.

Thereby, the electric power Wz1 required to manufacture one unit product at time t is
Wzl = (10 + 5 + 15) × 0.1 = 3 (kwh)
It became.

Therefore, the environmental load value (CO ₂ emission amount) A1 of power at time t is
A1 = 3 kWh × 0.37 kg-CO ₂ /kWh=1.11 kg-CO ₂
It becomes. By adding the environmental load value A2 (0.24 kg-CO ₂ ) due to the introduction of the above components to A1,
Total environmental load value: 1.35 kg-CO ₂
Was able to be calculated.
(Example 2)
In the second embodiment, the same parts as in the first embodiment are used, and the data at the time ti immediately after the start of work (one hour later) is acquired for the same manufacturing apparatuses 100a to 100c as in the first embodiment. Was calculated. Immediately after the start of work, the power for warming up increased in the manufacturing apparatuses 100a and 100c, and the power of each of the manufacturing apparatuses 100a to 100c was as follows.

Manufacturing apparatus 100a: 20 kW
Manufacturing apparatus 100b: 5 kW
Manufacturing apparatus 100c: 23 kW
Moreover, in any of the manufacturing apparatuses 100a to 100c, the manufacturing time was slightly increased to 0.125 hours.

Thereby, the electric power Wz2 required to manufacture one unit product at time ti is
WZ2 = (20 + 5 + 23) × 0.125 = 6 kWh
It became.

Therefore, the environmental load value (CO ₂ emissions) A1 at time ti immediately after the start of work is
A1 = 6 × 0.37 = 2.22 kg-CO ₂
It becomes. By adding the environmental load value A2 (0.24 kg-CO ₂ ) due to the introduction of the above components to A1,
Total environmental load value: 2.46 kg-CO ₂
Was able to be calculated.

As described above, the value A1 in Example 2 (2.22 kg-CO ₂₎ is twice the value A1 Example 1 (1.11kg-CO _2), than the normal time period immediately after the opening start It is clear that the environmental load value becomes large.

This information cannot be obtained by a conventional method, and can be usefully used as an index for reducing the environmental load by feeding back this information to the manufacturing process.
(Comparative example)
In this comparative example, the same manufacturing apparatuses 100a to 100c as those in Examples 1 and 2 were extracted, and the environmental load value of the unit product was calculated.

  However, since there is no real-time power data for each of the manufacturing apparatuses 100a to 100c, the environmental load value cannot be calculated in real time as in the first and second embodiments. Therefore, the average value of the amount of power consumed in one month (20 days) in each of the manufacturing apparatuses 100a to 100c was used. The average value was as follows.

Manufacturing apparatus 100a: Average 1900kwh
Manufacturing apparatus 100b: Average 800 kwh
Manufacturing apparatus 100c: Average 2900kwh
Further, since there is no data on the production rate of the unit product, the next unit product production number produced in one month was used instead.

Number of unit products manufactured: 1500 Based on these data, the monthly average value of power (Wz3) required to manufacture one unit product is
Wz3 = (1900 + 800 + 2900) × 11500 = 3.7 kWh
It became.

Thereby, the environmental load value A1 of electric power is
A1 = 3.7 × 0.37 = 1.4 kg-CO ₂
It becomes.

  In this way, it is possible to obtain the environmental load value A1 even in the comparative example, but since the value is an average value for one month, it does not reflect the temporal change in the amount of input resources or production time, and Cannot be adopted as information for improving the manufacturing process.

  Further, the manufacturing apparatus 200 includes a material consumption database 25 in which material names and material consumptions such as resources and parts consumed in the unit products 1a and 1b before processing are recorded, and unit products 1a and 1b before processing. An energy amount acquisition unit 26 that acquires the input amount of energy input to 1b is provided. The energy amount acquisition unit 26 consumed the processing of the unit products 1a and 1b by the manufacturing apparatus 200 from the power meter 17_1, the tap water meter 17_2, the oil meter 17_3, the city gas meter 17_4, and the like provided in the manufacturing apparatus 200.

  Returning to the description of the flowchart of FIG. 11, after a valid recording device is determined in step S31, the environmental load calculation device 20 transmits manufacturing start data to the wireless IC tags 3a and 3b (step S32). The wireless IC tags 3 a and 3 b that have received the production start data transmit the environmental load value recorded therein to the environmental load calculation device 20. The environmental load calculation device 20 sequentially receives the environmental load values recorded in the wireless IC tags 3a and 3b (step S33), and when reception of the environmental load values is completed, obtains time data at the time of reception and starts manufacturing.
