Description

Home Appliance Decomposing Time Measuring Method

The present invention relates to a method for measuring the disassembly time of home appliances, and more particularly, to a method for measuring the disassembly time of home appliances that can be utilized to develop environmentally friendly home appliances by efficiently measuring the disassembly time of home appliances at the end of product life. will be.

Recently, as the necessity of environmental protection increases day by day, the number of cases of developing environmentally friendly electronic products is increasing. In particular, in the case of home appliances that are distributed in any household, the recyclability is higher than that of other electronic products. Therefore, home appliances that have become impossible to use at home are generally collected and disassembled by the makers of home appliances and used to manufacture other home appliances or electronic products.

In particular, in order to improve the recyclability of household appliances and to facilitate their disassembly, conventionally, the decomposition time of household appliances is measured and quantified according to the actual measurement time, which is assumed by the manual decomposition. It is also used for evaluation of recyclability.

The conventional method for measuring the disintegration time when disassembling a home appliance manually is shown in FIG.

That is, after analyzing the fastening method of each component constituting the home appliance in the first step (S1), and analyzing the characteristics of the fastening element such as the fastening form of the part or the size of the fastened area in the second step (S2) When the same fastening component is used in the third and fourth steps, the number and the moving distance are calculated (S3, S4). In the fifth step, the decomposition tool used for disassembling the home appliance is analyzed (S5), and in the sixth step, the decomposition time is calculated by analyzing the decomposition operation of the worker who disassembles (S6), and in the seventh step, in the first step, The total decomposition time of the home appliance is calculated as the sum of the decomposition times considered until the sixth step (S7).

However, the conventional method for measuring the disintegration time of a home appliance uses an actual measurement value to calculate the disassembly time according to the fastening method and the characteristics of the fastening product in evaluating the disassembly time of the home appliance. There is a problem that the deviation is different depending on the experience of disassembling the product or using the disassembly tool.

In addition, it only measures the decomposition time, and does not provide information for actual product designers to analyze the weakness of home appliances based on the measured decomposition time, and only present a few general examples of the fastening method and the decomposition tool. However, the specific types of fastening methods and types of disassembly tools are not defined.

In addition, it does not explain how to analyze the decomposition operation, but only to analyze the decomposition operation, the results for the same household appliances may be different depending on the decomposer to decompose the household appliances, There is a problem that there is a high probability of error because there is no consideration of the weight and the accessibility of the affected parts.

The present invention has been made to solve the above problems of the prior art, the object of the present invention is to propose an evaluation criteria and methods that can quantitatively evaluate / analyze the decomposition time during the evaluation of the degradability of home appliances and derived accordingly It is to provide a method for measuring the decomposition time of home appliances that can realize the development of environmentally friendly products by reflecting the results in the development stage of home appliances.

Figure 2 is a flow chart illustrating a flow of a method for measuring home appliance decomposition time according to the present invention.

According to a characteristic of the home appliance decomposition time measuring method according to the present invention for solving the above problems, the first step of dividing the decomposition operation used when disassembling the household appliances into the operation element, the operation element divided in the first step It consists of a second step of calculating the time required for implementation by an internationally recognized standard time measurement method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Decomposition time measurement method of home appliances according to the present invention is configured as shown in FIG.

First, in the eleventh step, the disassembling operation of the home appliance is divided into a motion element. At this time, in the present invention, the operation of the decomposer for disassembling the home appliance is divided into operation elements, which are classified into operation elements consisting of catching, grasping, turning, viewing, and the like. (S11)

In the twelfth step, the operation elements classified in the eleventh step are allocated to the decomposition step. That is, when the decomposition step of the home appliance is divided into a decomposition step of supply time, decomposition time, movement time, and removal time, it indicates a step of analyzing and assigning which step belongs to the operation element classified in the eleventh step. (S12)

In the thirteenth step, it is determined whether the time required to perform the operation element is calculated by MTM II, which is a standard time measurement method of a classic PTS (Predetermined Time Standard), or by actual measurement. In other words, in order to convert the operation element into actual unit time, the operation element is classified into an operation element expressed by MTMII and an operation element that cannot be expressed. (S13)

In the thirteenth step, in the case of an operation element that can be represented by the MTM II, it is converted into a unit time value using a time measure unit (TMU) time unit, and in the fourteenth step, an operation element that cannot be expressed in an MTMII is operated through actual measurement. Estimate the time required to perform the element. (S14)

In the fifteenth step, the disassembly time for the actual fastening structure is estimated by classifying 18 fastening methods and characteristic elements used in actual home appliances based on the results of the 11 th to 14 th steps. Here, the 18 classifications include (Put On), Insert, Sliding Joint, Hang Up, Snap Fit, Screw Connection, Clamping Joint , Compression Joint, Extrusion Coat, Distort, Folded Seam Connection, Coil Up, Lock Form, Riveted Connection (Riveted connection), Pivot Riveted connection (Weld Joint), Weld Joint (Solder Joint), Glued Joint. (S15)

In the sixteenth step, the influence of the decomposition time due to the decomposition tool used for disassembly of the home appliance is analyzed. In the sixteenth step, the decomposition tool is classified into 11 types and the influence value of the decomposition tool for each decomposition tool is calculated. Here, the 11 classifications are Screwdriver / Wrench, Pliers, Diagonal Cutting Nipper, Screw-in Circuit Breaker, Shell Bit, Soldering Copper It consists of scissors, bolt cutter, chisel, mandrill & hammer, chisel & hammer. (S16)

In the seventeenth step, in addition to the fastening information of the home appliance, the handling and accessibility for each part affecting the decomposition time of the home appliance are analyzed. That is, the disassembly time value added for each component is analyzed in consideration of the weight, size, and disassembly accessibility of each component of the home appliance. (S17)

In the eighteenth step, the total decomposition time of the home appliance is determined according to the results of the eleventh to seventeenth steps, wherein the total decomposition time is a time required for performing an operation element according to the standard time measurement method, and the standard time. The time required to perform the operation elements not included in the measurement method, the time required to disassemble the fastening structure of the home appliance, the time required by the tool used to disassemble the home appliance, and the parts forming the home appliance This is accomplished by summing up the time added to disassemble each part, depending on the weight, size and explosive approach. (S18)

In the nineteenth step, the designer or decomposer of a home appliance is used to compare the individual decomposition time required to decompose the components constituting the product with the average decomposition time of the total decomposition time. Display to. Therefore, the designer can recognize a component having a poor degradability, analyze the source, and establish an improvement alternative of the component having a low resolution, and reflect it in the design of a home appliance. (S19)

Therefore, when the life of the home appliance is at the end, by using the method of measuring the decomposition time of the home appliance, such as to reduce the disassembly time of the home appliance at the disposal stage, to reduce the cost, while minimizing the cost of recycling and disassembly of the product It is possible to evaluate the degradability for shortening the time.
