2. Description of the Related Art Appropriate disposal of waste has recently been demanded from the viewpoints of resource reuse and prevention of environmental pollution.
When dismantling a used washing machine, it is necessary to consider the efficiency of dismantling, prevention of environmental pollution, and the reuse of resources. Proper automatic dismantling of various washing machines encounters two challenges. The first problem is a problem related to identification of a washing machine. In order to automatically disassemble various types of washing machines, it is necessary to disassemble in consideration of differences in structure due to differences in types of washing machines. Whether a washing machine is a two-tub washing machine or a one-tank (fully automatic) washing machine is easy for human beings. However, identification has not been performed automatically so far. When considering resource reuse and efficient disassembly, the second problem is how to dismantle from an appropriate part. In this way, even if the washing machine is dismantled, it does not mean that it is all crushed or crushed.

[0003] In the dismantling of a washing machine, it is necessary to pay attention to the handling of a motor made of metal and robust. The reason is,
Parts such as the housing of the washing machine are made of soft materials such as plastics and thin metal plates, and are easily crushed. The motor cannot be crushed with a crusher that is manufactured and crushes soft materials such as plastics and thin metal plates. In addition, there is a demand that the metal material constituting the motor be recovered separately from the casing which is crushed and disposed because it can be reused as a valuable resource.

[0004] Japanese Patent Application Laid-Open No. Hei 5-124771 discloses a technique using a press mechanism for dismantling a waste washing machine. That is, the dismantling technique disclosed in Japanese Patent Application Laid-Open No. 5-127771 is a method in which the press unit is advanced and retracted in the axial direction of the washing tub so as to face the motor unit of the washing machine in which the press device is laid down, and the motor unit is shot out.

One-Tank (Fully Automatic) Washing Machine A one-tank (fully automatic) washing machine 3 is shown in FIG.
As illustrated in FIG. 3B as a cross-sectional view taken along line Y2-Y2 and FIG. 3B as a cross-sectional view taken along line X2-X2 in FIG. And a washing / dewatering tub 31 made of plastic resin and a motor 36 for rotating the washing / dehydrating tub 31 provided inside the housing 30. The motor 36 is normally fixed to a bottom plate 39 made of resin, and rotates the washing / dehydrating tub 31. Motor 36
The bottom of the washing / dewatering tub 31 is connected to the bottom of the washing / dewatering tub 31 by a shaft 33 via a rotating mechanism (not shown).
The rotation and the rotation mechanism cause the washing / dehydrating tub 31 to perform desired forward / reverse rotation. An operation unit 40 for operating the one-tub type (fully automatic) washing machine 3 is provided at an upper portion of the housing 30. The operation unit 40 is provided with a rotary dial or the like on a plastic resin plate. 1 tank type (fully automatic type)
The washing machine 3 is provided with a water supply pipe, a drain pipe, a wiring member, and the like in addition to those described above, but illustration is omitted. 1
When disassembling the tub-type (fully automatic) washing machine 3, the tub-type (full-automatic) washing machine 3 is made of a soft member such as a plastic resin or a thin iron plate.
The housing 30, the washing / dewatering tub 31, the operation unit 40, and the like are easy to disassemble, but the motor 36, the shaft 33,
The rotating mechanism and the like, whose illustration is omitted, are made of metal and are rigidly manufactured, cannot be crushed similarly to members made of plastic resin, thin iron plate and the like, and have different methods of disposal after disassembly and reuse. Therefore, the housing 30, the washing / dewatering tub 31, the operation unit 40, and the like include the motor 36, the bottom plate 39,
It is necessary to distinguish it from the rotation mechanism. Therefore, in the embodiment of the present invention, the bottom of the washing / dewatering tub 31 connected to the metal shaft 33 is cut along the cutting line C2-C2 for the one-tub type (fully automatic) washing machine 3. I do.

The identification principle of the washing machine will be described. The inventor of the present application has a two-tub washing machine 1 and a one-tub (fully automatic) washing machine 3.
As a result of studying a method of automatically determining the width W of the washing machine,
It has been found that the washing machine can be identified by judging the ratio of the depth D to the depth D. Since the two-tub washing machine 1 has two tubs, a washing tub 11 and a dehydration tub 12, the planar structure is a horizontally long rectangle, and the width is smaller than that of a one-tub type (fully automatic) washing machine described later. The ratio of W1 / depth D1 is large or depth D
The ratio of 1 / width W1 is small. Conversely, one tank type (fully automatic type)
The washing machine 3 has only a washing / dehydrating tub 31 and has a single tub, so that the planar structure is almost square. Therefore, in the case of the one-tub type (fully automatic type) washing machine 3, the ratio of the width W2 / depth D2 is close to 1, or the ratio of the depth D2 / width W2 is also close to 1. According to the results of a survey on various washing machines by the inventor of the present application, when depth D / width W ≧ predetermined value (1), the washing machine is a one-tub type (fully automatic) washing machine 3
It turns out that it may be identified as. In the present embodiment, the predetermined value in Equation 1 is set to 0.7. This predetermined value can be changed as appropriate in addition to 0.7. Thus, in the present invention, the ratio between the depth D and the width W is set to 2
The tub-type washing machine 1 is distinguished from the one-tub-type (fully automatic) washing machine 3. Based on the above knowledge, in the washing machine identification device 100, the width W and the depth D of the washing machine to be dismantled are measured, and the ratio of the measured width W to the depth D is calculated, and the ratio is equal to or more than a predetermined value ( In this embodiment, it is determined whether or not the ratio is 0.7 or more.
Or a one-tank (fully automatic) washing machine 3 is identified.

2. Width / Depth Measurement Referring to FIG. 4, measurement of width W and depth D of a washing machine to be dismantled in washing machine identification device 100 will be described.
The washing machine identification device 100 includes a cylinder 101, an opening / closing centering flapper 102, 103, a centering air-cylinder 104, 105, an opening / closing mechanism 106,
It has a wire-type linear encoder 107, an ultrasonic displacement sensor 108, and a cylinder 109. The computer 200 measures the width W and the depth D of the washing machine to be dismantled in cooperation with the washing machine identification device 100. The washing machine to be dismantled received by the dismantling device is transported over a roller conveyor (not shown) with the bottom surface in the forward direction, with the front surface facing upward, and the washing machine in the dismantling device is identified. It is transferred to the device 100. The washing machine to be dismantled is pushed by the pressing member, and the bottom surface abuts against a mechanical stopper to stop the transfer. Thereby, the positioning of the washing machine in the traveling direction is performed. Next, air for centering
The cylinders 104, 105 are operated to move the openable / closable centering flapper 102, 103, so that the washing machine is centered in the width direction such that the center in the width direction is located at the center line CC. In this centering state, the wire-type linear encoder 107 operates to measure the width W of the washing machine. The width W of the washing machine measured by the linear encoder 107 is input to the computer 200, subjected to signal processing, and stored. Simultaneously with the measurement of the width of the washing machine, the ultrasonic displacement sensor 108 operates to measure the distance to the upper surface of the washing machine located below and to be dismantled. The computer 200 inputs the detection value of the ultrasonic displacement sensor 108. Since the distance d0 from the tip of the ultrasonic displacement sensor 108 to the base 111 has been input to the computer 200 in advance, the computer 200 inputs the measurement distance d1 of the ultrasonic displacement sensor 108 and calculates (d0−d
1) is calculated and the depth D of the washing machine to be dismantled is D = (d
Calculate the dimension of 0-d1). As described above, the wire-type linear encoder 107 in the washing machine identification device 100
And the measurement value of the ultrasonic displacement sensor 108 is taken into the computer 200, and the width W and depth D of the washing machine to be dismantled can be calculated almost simultaneously.

3. Determination of Type of Washing Machine The computer 200 calculates the ratio D / W by dividing the depth D of the washing machine measured as described above by the measured width W.
When the ratio D / W is equal to or greater than a predetermined value, for example, 0.7, the computer 200 identifies that the washing machine to be dismantled is the one-tank (fully automatic) washing machine 3 and determines the ratio D / W. When W is less than 0.7, the washing machine to be dismantled is identified as the two-tub washing machine 1. Contrary to the above ratio calculation, the computer 200 calculates W / D, and if W / D is less than a predetermined value, for example, less than 1.4, the washing machine to be dismantled is one-tank type (fully automatic type). Identified as washing machine 3 and W / D is 1.4
In this case, the washing machine to be dismantled can be identified as the two-tub washing machine 1. As described above, it is possible to automatically determine whether the washing machine to be dismantled is the two-tub washing machine 1 or the one-tank (fully automatic) washing machine 3 by a relatively simple method.

When the measurement of the depth D and the width W of the washing machine to be dismantled, and the identification of the washing machine based on the calculation of the ratio D / W (or W / D) are completed, the washing machine to be dismantled is completed. Is pushed by the cylinder 101 to the right in FIG. At this time, the right side flapper 103 is raised by the cylinder 109 as illustrated by a broken line so as not to hinder movement of the washing machine to be dismantled.

The computer 200 responds to the identification result by
The push stroke of the cylinder 101 is controlled. When the washing machine to be dismantled is identified as the two-tub washing machine 1, for example, after being moved long and shifting to the next bottom frame cutting process,
The process proceeds to the measurement of the bottom of the washing tub 11 for estimating the cutting position of the washing machine. When the washing machine to be dismantled is identified as a single-tub type (fully automatic) washing machine 3, for example, the washing / dehydrating tub 3 is moved shortly to estimate a cutting position of the washing machine.
Go to bottom measurement of 1.

4. When the washing machine targeted for bottom frame cutting and dismantling in the case of the two-tub washing machine is identified as the two-tub washing machine 1,
The washing machine is conveyed to the bottom frame cutting device 300 illustrated in FIG. The bottom frame cutting device 300 cuts the bottom plate 19 along a cutting line C12-C12 of the two-tub washing machine 1 to separate a portion where the motor 16 is attached and a portion where the motor 18 is attached. Bottom frame cutting device 300
Are pushed on the support frame 301, the circular metal cutting saw 303 provided to be able to move up and down along the support frame 301, the table 307 on which the two-tub washing machine 1 is mounted, and the table 307. A locking member 3 which abuts against the bottom of the coming two-tub washing machine 1 to stop the movement and position the bottom of the two-tub washing machine 1.
05, the two-tub washing machine 1 is sandwiched on both sides to fix the two-tub washing machine 1 and to be movable in a direction perpendicular to the paper surface. The cutting line on the bottom plate 19 of the two-tub washing machine 1 is used for circular metal cutting. It has a lateral support mechanism 309 that can be matched to the saw 303. The two-tub washing machine 1 pushed by the pressing member rides on the table 307 and stops moving (transporting) when the bottom plate 19 of the two-tub washing machine 1 comes into contact with the locking member 305. The locking member 305 is provided with a load cell,
When the computer 200 determines that the value of the load cell is equal to or more than the predetermined value, the movement of the two-tub washing machine 1 by the cylinder 101 is stopped, and the two-tub washing machine 1 is sandwiched by the lateral support mechanism 309 to remove the circular metal. The horizontal support mechanism 309 is moved in the direction perpendicular to the plane of the paper so that the cutting line C12-C12 of the two-tub washing machine 1 coincides with the line of the cutting saw 303. In the present embodiment, the cutting line C12-C12 is located at the center of the width W1. Computer 20
0 stores the measured values of the width W1 and the depth D1 of the two-tub washing machine 1, and the above-described positioning by the lateral support mechanism 309 can be easily performed. When the cutting line C12-C12 of the two-tub washing machine 1 coincides with the surface of the circular metal cutting saw 303, the computer 200 rotates the circular metal cutting saw 303 and lowers it from top to bottom. As a result, the bottom plate 19 of the two-tub washing machine 1 is cut along the cutting line C12-C1.
Along 2, the bottom plate 19 is cut in two. At this time, since the upper part of the housing 10 is not cut, the two-tub washing machine 1 is not disassembled. In the present embodiment, the bottom frame cutting device 300 uses a tip saw having a diameter of 610 mm as the circular metal cutting saw 303 by inverter control for about 3 hours.
The bottom plate 19 of the two-tub washing machine 1 is rotated at 00 rotations / minute and moved vertically along the support frame 301.
Is cut at a predetermined height from the bottom in the depth direction of the two-tub washing machine 1, for example, at a height of 200 mm.

4. Estimating the bottom position of the washing tub As a method of estimating the cutting position of the washing machine,
The bottom of the washing tub 11 for the tub washing machine 1 and the bottom of the washing / dehydrating tub 31 for the washing tub 31 (fully automatic) washing machine 3 are set at the cutting position. As a stage prior to the cutting, the position of the bottom of the washing tub 11 of the two-tub washing machine 1 or the bottom of the washing / dehydrating tub 31 of the one-tank (fully automatic) washing machine 3 is detected. As described above, since the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 is easier to cut than the motor portion,
The position of the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 is estimated. The bottom measurement is performed similarly for the two-tub type washing machine 1 and the one-tub type (fully automatic) washing machine 3. Two-tub type washing machine 1 in which bottom plate 19 is divided into two or one-tub type (fully automatic) type washing machine 3
Is transported to the washing tub bottom measuring device 400 illustrated in FIG. The bottom measuring device 400 includes a table 401 movable in a direction perpendicular to the paper surface, a locking member 403, and a lifting member 4
05 and the ultrasonic sensor 40 mounted on the elevating member 405
And 7. The washing machine to be dismantled is placed on the table 401. The elevating member 405 is pressed until the washing machine to be dismantled contacts the locking member 403. The bottom plate 19 or the bottom plate 39 of the washing machine to be dismantled in contact with the locking member 403 is positioned by the locking member 403. Since the computer 200 stores the measured value of the depth D of the washing machine, the washing / dewatering tub 31 of the washing tub 11 of the two-tank washing machine 1 or the washing / dewatering tub 31 of the one-tank (fully automatic) washing machine 3 is located substantially at the center. I understand. Therefore, the computer 200 controls the elevating member 405 on which the ultrasonic sensor 407 is mounted to adjust the height position of the ultrasonic sensor 407 so that the direction of the ultrasonic sensor 407 is directed to the washing tub 11 or the washing / dewatering tub 31. The elevating member 405 is positioned in the height direction so as to be directed substantially to the center. The computer 200 moves the table 401 in the direction perpendicular to the plane of the paper to move the washing machine placed on the table 401 in the direction perpendicular to the plane of the paper (fixing the table 401 and moving the ultrasonic sensor 407 in the direction perpendicular to the plane of the paper). May be moved). Accordingly, the ultrasonic sensor 407 continuously measures the distance from the top of the washing machine to the symmetric object.
The computer 200 detects the maximum value of the reading of the ultrasonic sensor 407. This maximum value is equal to 2 from the ultrasonic sensor 407.
Distance to the bottom of the washing tub 11 of the tub washing machine 1 or
This corresponds to the distance from the ultrasonic sensor 407 to the bottom of the washing / dehydrating tub 31 of the one-tub type (fully automatic type) washing machine 3. That is, the computer 200 continuously reads the detection value of the ultrasonic sensor 407 as the table 401 moves in the direction perpendicular to the plane of the paper, and reads the distance to the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31. Measure the distance. Distance d10 from tip of ultrasonic sensor 407 to locking member 403
Is known in advance. The distance d11 from the tip of the ultrasonic sensor 407 to the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 was measured by the ultrasonic sensor 407. Therefore, in the computer 200, (d10-d1
By calculating 1), the distance from the bottom plate 19 to the bottom of the washing tub 11 in the two-tub washing machine 1 or the distance from the bottom plate 39 to the bottom of the washing / dewatering tub 31 in the one-tank (fully automatic) washing machine 3 Can be calculated.

4a. Estimation of the bottom position of the washing tub As described above, the cutting line C11-C11 of the two-tub washing machine 1
Or the cutting line C2-C2 of the 1-tank (fully automatic) washing machine 3
Is estimated, but the above estimated position is corrected to make the cutting position more accurate. As the correction value, a cutting position is corrected based on the value obtained by actually measuring various washing machines in advance.

5. Cutting of the washing machine After the distance from the bottom plate of the washing machine to be dismantled to the bottom of the washing tub is calculated, the washing machine to be dismantled is transferred to the cutting device 500 illustrated in FIG. Cutting device 5
00 is a feeding device 501 using a ball screw for pressing and positioning the washing machine, a table 503 on which the washing machine is mounted, and a table 5.
Cutting machine (not shown) for cutting the washing machine placed on 03
And The ball screw feeder 501 pushes the washing machine under the control of the computer 200 such that the bottom of the washing tub is located below the cutting machine. When the cutting line C11-C11 of the two-tank washing machine 1 or the cutting line C2-C2 of the one-tank (fully automatic) washing machine 3 is located at the lower part of the cutting machine, the computer 200 lowers the cutting machine. The cutting machine is a shearing-type cutting machine in the present embodiment, and has a blade longer than the width of the washing machine. The blade descends from above and halves the housing at the bottom of the washing tub of the washing machine. In this cutting, the metal shaft 1 in the two-tub washing machine 1
The motors 16 and 18 as well as parts of 3 and 17 are not cut. However, since the bottom plate 19 is cut by the bottom frame cutting device 300 so as to separate the motor 16 and the motor 18, the bottom plate 19 to which the motor 16 is fixed by the cutting by the cutting machine 505 and the motor 18 are fixed. And the bottom plate 19 which is formed. Therefore, the blade of the cutting machine only needs to be able to cut the casing 10 or the casing 30 made of plastic resin. In addition, since a rigid object such as the motor 16 is not cut, blade spilling does not occur and the life of the blade is extended. In addition, cutting can be performed with a small and small cutting machine.

The above-mentioned cutting by the cutting machine causes crushed pieces of the casing 10 or the casing 30 to scatter.
It is a small piece of thin iron plate that can be disposed of with the subsequent resin.

6. Subsequent Disposal As described above, the two-tub washing machine 1 is divided into a bottom plate 19 to which the motor 16 is fixed, a bottom plate 19 to which the motor 18 is fixed, and an upper part of the housing 10. Thereafter, the bottom plate 19 to which the motor 16 is attached and the bottom plate 19 to which the motor 18 is attached are separated from the bottom plate 19 by removing the motor 16 and the motor 18, respectively.
For the motor 6 and the motor 18, disassembly of the motor / reducer, collection of the condenser, collection of the casing, and the like are performed. Thereafter, the casing 10 is subjected to a crushing process. The one-tub type (fully automatic) washing machine 3 is also post-processed similarly to the two-tub type washing machine 1. Before disassembly and crushing of the single-tub type (fully automatic) washing machine 3, the salt water stored as a balancer is collected. As described above, since the same material is disposed, the classification is easy, the disposal can be appropriately performed, and the recycling can be utilized.

For example, other width measuring means can be used instead of the wire type linear encoder 107 as the means for measuring the width of the washing machine to be dismantled in FIG. Similarly, other depth D measuring means can be used instead of the ultrasonic displacement sensor 108 in FIG. The measuring means itself for measuring the width and depth corresponds to various well-known and commonly used means. Similarly, the circular metal cutting saw 303 of the bottom frame cutting device 300 in FIG. 5 can be replaced with another alternative means. The configurations of the ultrasonic sensor 407 and the elevating member 405 in FIG. 6 can be appropriately replaced with alternative means. The various means in FIG. 7 can be replaced with other various alternative means. Further, in the above-described embodiment, the case where the computer 200 is shared as the control means of the device for identifying the type of the washing machine, the cutting position estimating device of the washing machine, and the device for disassembling the washing machine has been described. Without sharing 200,
An independent computer may be provided for each of the washing machine identification device 100, the bottom frame cutting device 300, the bottom measuring device 400, and the cutting device 500. However, for example, the bottom frame cutting device 3
As the measurement data necessary for 00, data measured and held by a computer in the washing machine identification device 100 is used.

Further, the device configuration for implementing the method for identifying the type of the washing machine, the method for estimating the cutting position of the washing machine, and the method for disassembling the washing machine will be described. Can be adopted.

When dismantling a used washing machine, it is necessary to consider the efficiency of dismantling, prevention of environmental pollution, and the reuse of resources. Proper automatic dismantling of various washing machines encounters two challenges. The first problem is a problem related to identification of a washing machine. In order to automatically disassemble various types of washing machines, it is necessary to disassemble in consideration of differences in structure due to differences in types of washing machines. Whether a washing machine is a two-tub washing machine or a one-tank (fully automatic) washing machine is easy for human beings. However, identification has not been performed automatically so far. When considering resource reuse and efficient disassembly, the second problem is how to dismantle from an appropriate part. In this way, even if the washing machine is dismantled, it does not mean that it is all crushed or crushed.

[0003] In the dismantling of a washing machine, it is necessary to pay attention to the handling of a motor made of metal and robust. The reason is,
Parts such as the casing of the washing machine are made of soft materials such as plastics and thin metal plates, and are easily crushed and relatively easy to dispose of after crushing. The motor cannot be crushed with a crusher that is manufactured and crushes soft materials such as plastics and thin metal plates. In addition, there is a demand that the metal material constituting the motor be recovered separately from the casing which is crushed and disposed because it can be reused as a valuable resource.

[0004] Japanese Patent Application Laid-Open No. Hei 5-124771 discloses a technique using a press mechanism for dismantling a waste washing machine. That is, the dismantling technique disclosed in Japanese Patent Application Laid-Open No. 5-127771 is a method in which the press unit is advanced and retracted in the axial direction of the washing tub so as to face the motor unit of the washing machine in which the press device is laid down, and the motor unit is shot out.

The advantage is that

One-Tank (Fully Automatic) Washing Machine A one-tank (fully automatic) washing machine 3 is shown in FIG.
As illustrated in FIG. 3B as a cross-sectional view taken along line Y2-Y2 and FIG. 3B as a cross-sectional view taken along line X2-X2 in FIG. A washing / dehydrating tub 31 mainly provided in the housing 30 and made of plastic resin, and a motor 36 for rotating the washing / dehydrating tub 31
And The motor 36 is usually at the bottom of the washing / dehydrating tub 31.
And rotating the washing / dehydrating tub 31.
The motor 36 and the bottom of the washing / dewatering tub 31 are connected by a shaft 33 via a rotating mechanism (not shown).
The washing / dewatering tub 3 is rotated by the rotation of the motor 36 and the rotation mechanism.
1 performs the desired forward / reverse rotation. An operation unit 40 for operating the one-tub type (fully automatic) washing machine 3 is provided at an upper portion of the housing 30. The operation unit 40 is provided with a rotary dial or the like on a plastic resin plate. The one-tub type (fully automatic) washing machine 3 has a water pipe,
Although a drain pipe, a wiring member, and the like are provided, illustration is omitted. When disassembling the one-tub type (fully automatic) washing machine 3, the housing 30, the washing / dewatering tub 31, and the operation unit 4, which are formed of soft members such as plastic resin and thin iron plate.
0 and the like are easy to disassemble (crush) and disassemble, but the motor 36, the shaft 33, and the rotating mechanism (not shown) are made of metal and are rigidly manufactured. It cannot be crushed like components made of plastics, etc., and the methods of disposal after dismantling and the methods of reuse differ. Therefore, the housing 30, the washing / dewatering tub 31, the operation unit 40, and the like need to be separated from the motor 36, the bottom plate 39, the rotation mechanism, and the like. Therefore, in the embodiment of the present invention, the bottom of the washing / dewatering tub 31 connected to the metal shaft 33 is cut along the cutting line C2-C2 for the one-tub type (fully automatic) washing machine 3. I do.

The identification principle of the washing machine will be described. The inventor of the present application has a two-tub washing machine 1 and a one-tub (fully automatic) washing machine 3.
As a result of studying a method of automatically determining the width W of the washing machine,
It has been found that the washing machine can be identified by the judgment of the ratio of the depth D to the depth D = D / W. Of course, as a ratio,
The reverse ratio = W / D may be used.
In the following, the case where D / W is used as the ratio will be described.
Bell. Since the two-tub washing machine 1 has two tubs, a washing tub 11 and a dehydration tub 12, the planar structure is a horizontally long rectangle, and the width is smaller than that of a one-tub type (fully automatic) washing machine described later. W1 /
The ratio of depth D1 is large, or the ratio of depth D1 / width W1 is small. On the other hand, the one-tub type (fully automatic) washing machine 3 has only the washing / dehydrating tub 31, and since the number of tubs is one, the planar structure is almost square. Therefore, in the case of the one-tub type (fully automatic type) washing machine 3, the ratio of the width W2 / depth D2 is close to 1, or the ratio of the depth D2 / width W2 is also close to 1. According to the results of a survey on various washing machines by the inventor of the present application, when ratio = depth D / width W ≧ predetermined value (1), the washing machine is a one-tub type (fully automatic) washing machine. 3
It turns out that it may be identified as. In the present embodiment, the predetermined value in Equation 1 is set to 0.7. This predetermined value can be changed as appropriate in addition to 0.7. Rice cake
When the ratio is W / D, the judgment of Expression 1 is reversed.
You. Thus, in the present invention, the ratio of the depth D to the width W = D / W (or W / D) is set to the two-tub washing machine 1
It is used as a criterion for identification from the tub-type (fully automatic) washing machine 3.
Based on the above findings, in the washing machine identification device 100,
The width W and the depth D of the washing machine to be dismantled are measured, and the ratio between the measured width W and the depth D is calculated, and the ratio is equal to or more than a predetermined value (the ratio is 0.7 or more in the present embodiment). Is determined to determine whether the washing machine is a two-tub washing machine 1 or a one-tank (fully automatic) washing machine 3.

2. Width / Depth Measurement Referring to FIG. 4, measurement of width W and depth D of a washing machine to be dismantled in washing machine identification device 100 will be described.
The washing machine identification device 100 includes a cylinder 101, an opening / closing centering flapper 102, 103, a centering air-cylinder 104, 105, an opening / closing mechanism 106,
It has a wire-type linear encoder 107, an ultrasonic displacement sensor 108, and a cylinder 109. The computer 200 measures the width W and the depth D of the washing machine to be dismantled in cooperation with the washing machine identification device 100. The washing machine to be dismantled received by the dismantling device is transported over a roller conveyor (not shown) with the bottom surface in the forward direction, with the front surface facing upward, and the washing machine in the dismantling device is identified. It is transferred to the device 100. The washing machine to be dismantled is pushed by the pressing member, and the bottom surface abuts against a mechanical stopper to stop the transfer. Thereby, the positioning of the washing machine in the traveling direction is performed. Next, air for centering
The cylinders 104, 105 are operated to move the openable / closable centering flapper 102, 103, so that the washing machine is centered in the width direction such that the center in the width direction is located at the center line CC. In this centering state, the wire-type linear encoder 107 operates to measure the width W of the washing machine. The width W of the washing machine measured by the linear encoder 107 is input to the computer 200, subjected to signal processing, and stored. Simultaneously with the measurement of the width of the washing machine, the ultrasonic displacement sensor 108 operates to measure the distance to the upper surface of the washing machine located below and to be dismantled. The computer 200 inputs the detection value of the ultrasonic displacement sensor 108. Since the distance d0 from the tip of the ultrasonic displacement sensor 108 to the base 111 has been input to the computer 200 in advance, the computer 200 inputs the measurement distance d1 of the ultrasonic displacement sensor 108 and calculates (d0−d
1) is calculated and the depth D of the washing machine to be dismantled is D = (d
Calculate the dimension of 0-d1). As described above, the wire-type linear encoder 107 in the washing machine identification device 100
And the measurement value of the ultrasonic displacement sensor 108 is taken into the computer 200, and the width W and depth D of the washing machine to be dismantled can be calculated almost simultaneously.

3. Determination of Type of Washing Machine The computer 200 calculates the ratio D / W by dividing the depth D of the washing machine measured as described above by the measured width W.
When the ratio D / W is equal to or greater than a predetermined value, for example, 0.7, the computer 200 identifies that the washing machine to be dismantled is the one-tank (fully automatic) washing machine 3 and determines the ratio D / W. When W is less than 0.7, the washing machine to be dismantled is identified as the two-tub washing machine 1. Contrary to the above ratio calculation, the computer 200 calculates W / D, and if W / D is less than a predetermined value, for example, less than 1.4, the washing machine to be dismantled is one-tank type (fully automatic type). Identified as washing machine 3 and W / D is 1.4
In this case, the washing machine to be dismantled can be identified as the two-tub washing machine 1. As described above, it is possible to automatically determine whether the washing machine to be dismantled is the two-tub washing machine 1 or the one-tank (fully automatic) washing machine 3 by a relatively simple method.

When the measurement of the depth D and the width W of the washing machine to be dismantled, and the identification of the washing machine based on the calculation of the ratio D / W (or W / D) are completed, the washing machine to be dismantled is completed. Is pushed by the cylinder 101 to the right in FIG. At this time, the right side flapper 103 is raised by the cylinder 109 as illustrated by a broken line so as not to hinder movement of the washing machine to be dismantled.

The computer 200 responds to the identification result by
The push stroke of the cylinder 101 is controlled. When the washing machine to be dismantled is identified as the two-tub washing machine 1, for example, after being moved long and shifting to the next bottom frame cutting process,
The process proceeds to the measurement of the bottom of the washing tub 11 for estimating the cutting position of the washing machine. When the washing machine to be dismantled is identified as a single-tub type (fully automatic) washing machine 3, for example, the washing / dehydrating tub 3 is moved shortly to estimate a cutting position of the washing machine.
Go to bottom measurement of 1.

4. When the washing machine targeted for bottom frame cutting and dismantling in the case of the two-tub washing machine is identified as the two-tub washing machine 1,
The washing machine is conveyed to the bottom frame cutting device 300 illustrated in FIG. The bottom frame cutting device 300 cuts the bottom plate 19 along a cutting line C12-C12 of the two-tub washing machine 1 to separate a portion where the motor 16 is attached and a portion where the motor 18 is attached. Bottom frame cutting device 300
Are pushed on the support frame 301, the circular metal cutting saw 303 provided to be able to move up and down along the support frame 301, the table 307 on which the two-tub washing machine 1 is mounted, and the table 307. A locking member 3 which abuts against the bottom of the coming two-tub washing machine 1 to stop the movement and position the bottom of the two-tub washing machine 1.
05, the two-tub washing machine 1 is sandwiched on both sides to fix the two-tub washing machine 1 and to be movable in a direction perpendicular to the paper surface. The cutting line on the bottom plate 19 of the two-tub washing machine 1 is used for circular metal cutting. It has a lateral support mechanism 309 that can be matched to the saw 303. The two-tub washing machine 1 pushed by the pressing member rides on the table 307 and stops its movement (conveyance) when the bottom plate 19 of the two-tub washing machine 1 contacts the locking member 305.
You. Next, the two-tub washing machine 1 is sandwiched by the lateral support mechanism 309, and the horizontal support mechanism 309 is positioned so that the cutting line C12-C12 of the two-tub washing machine 1 coincides with the line of the circular metal cutting saw 303. In the direction perpendicular to the plane of the drawing. Cutting line C
12-C12 is assumed to be at the center of the width W1 in the present embodiment. The computer 200 stores the measured values of the width W1 and the depth D1 of the two-tub washing machine 1, and the above-described positioning by the lateral support mechanism 309 can be easily performed. Cutting line C12-C of the two-tub washing machine 1
When 12 coincides with the surface of the circular metal cutting saw 303, the computer 200 rotates the circular metal cutting saw 303 and lowers it from top to bottom. As a result, the bottom plate 19 of the two-tub washing machine 1 is moved along the cutting line C12-C12,
The bottom plate 19 is cut in two. At this time, since the upper part of the housing 10 is not cut, the two-tub washing machine 1 is not disassembled. In the present embodiment, the bottom frame cutting device 3
00 is a circular metal cutting saw 303 having a diameter of 610 mm.
Is rotated at about 300 revolutions / minute by an inverter control, and is moved vertically along the support frame 301 so that the center of the bottom plate 19 of the two-tub washing machine 1 is substantially aligned with the center of the two-tub washing machine 1. At a predetermined height from the bottom in the depth direction,
For example, it is cut at a height of 200 mm.

4. Estimating the bottom position of the washing tub As a method of estimating the cutting position of the washing machine,
The bottom of the washing tub 11 for the tub washing machine 1 and the bottom of the washing / dehydrating tub 31 for the washing tub 31 (fully automatic) washing machine 3 are set at the cutting position. As a stage prior to the cutting, the position of the bottom of the washing tub 11 of the two-tub washing machine 1 or the bottom of the washing / dehydrating tub 31 of the one-tank (fully automatic) washing machine 3 is detected. As described above, since the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 is easier to cut than the motor portion,
The position of the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 is estimated. The bottom measurement is performed similarly for the two-tub type washing machine 1 and the one-tub type (fully automatic) washing machine 3. Two-tub type washing machine 1 in which bottom plate 19 is divided into two or one-tub type (fully automatic) type washing machine 3
Is transported to the washing tub bottom measuring device 400 illustrated in FIG. The bottom measuring device 400 includes a table 401 movable in a direction perpendicular to the paper surface, a locking member 403, and a lifting member 4
05 and the ultrasonic sensor 40 mounted on the elevating member 405
And 7. The washing machine to be dismantled is placed on the table 401. The elevating member 405 is pressed until the washing machine to be dismantled contacts the locking member 403. The bottom plate 19 or the bottom plate 39 of the washing machine to be dismantled in contact with the locking member 403 is positioned by the locking member 403. Since the computer 200 stores the measured value of the depth D of the washing machine, the washing / dewatering tub 31 of the washing tub 11 of the two-tank washing machine 1 or the washing / dewatering tub 31 of the one-tank (fully automatic) washing machine 3 is located substantially at the center. I understand. Therefore, the computer 200 controls the elevating member 405 on which the ultrasonic sensor 407 is mounted to adjust the height position of the ultrasonic sensor 407 so that the direction of the ultrasonic sensor 407 is directed to the washing tub 11 or the washing / dewatering tub 31. The elevating member 405 is positioned in the height direction so as to be directed substantially to the center. The computer 200 moves the table 401 in the direction perpendicular to the plane of the paper to move the washing machine placed on the table 401 in the direction perpendicular to the plane of the paper (fixing the table 401 and moving the ultrasonic sensor 407 in the direction perpendicular to the plane of the paper). May be moved). Accordingly, the ultrasonic sensor 407 continuously measures the distance from the top of the washing machine to the symmetric object.
The computer 200 detects the maximum value of the reading of the ultrasonic sensor 407. This maximum value is equal to 2 from the ultrasonic sensor 407.
Distance to the bottom of the washing tub 11 of the tub washing machine 1 or
This corresponds to the distance from the ultrasonic sensor 407 to the bottom of the washing / dehydrating tub 31 of the one-tub type (fully automatic type) washing machine 3. That is, the computer 200 continuously reads the detection value of the ultrasonic sensor 407 as the table 401 moves in the direction perpendicular to the plane of the paper, and reads the distance to the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31. Measure the distance. Distance d10 from tip of ultrasonic sensor 407 to locking member 403
Is known in advance. The distance d11 from the tip of the ultrasonic sensor 407 to the bottom of the washing tub 11 or the bottom of the washing / dewatering tub 31 was measured by the ultrasonic sensor 407. Therefore, in the computer 200, (d10-d1
By calculating 1), the distance from the bottom plate 19 to the bottom of the washing tub 11 in the two-tub washing machine 1 or the distance from the bottom plate 39 to the bottom of the washing / dewatering tub 31 in the one-tank (fully automatic) washing machine 3 Can be calculated.

4a. Estimation of the bottom position of the washing tub As described above, the cutting line C11-C11 of the two-tub washing machine 1
Or the cutting line C2-C2 of the 1-tank (fully automatic) washing machine 3
Is estimated, but the above estimated position is corrected to make the cutting position more accurate. As the correction value, a cutting position is corrected based on the value obtained by actually measuring various washing machines in advance.

5. Cutting of the washing machine After the distance from the bottom plate of the washing machine to be dismantled to the bottom of the washing tub is calculated, the washing machine to be dismantled is transferred to the cutting device 500 illustrated in FIG. Cutting device 5
00 is a feeding device 501 using a ball screw for pressing and positioning the washing machine, a table 503 on which the washing machine is mounted, and a table 5.
Cutting machine (not shown) for cutting the washing machine placed on 03
And The ball screw feeder 501 pushes the washing machine under the control of the computer 200 such that the bottom of the washing tub is located below the cutting machine. When the cutting line C11-C11 of the two-tank washing machine 1 or the cutting line C2-C2 of the one-tank (fully automatic) washing machine 3 is located at the lower part of the cutting machine, the computer 200 lowers the blade of the cutting machine . The cutting machine is a shearing-type cutting machine in the present embodiment, and has a blade longer than the width of the washing machine. The blade descends from above and halves the housing at the bottom of the washing tub of the washing machine. In this cutting, the motors 16 and 18 as well as the parts of the metal shafts 13 and 17 in the two-tub washing machine 1 are not cut. However, since the bottom plate 19 is cut by the bottom frame cutting device 300 so as to separate the motor 16 and the motor 18, the bottom plate 19 to which the motor 16 is fixed by cutting with the blade of the cutting machine and the motor 18 are separated. It is bisected into a fixed bottom plate 19. Therefore, the blade of the cutting machine is made of thin metal plate and plastic resin
What is necessary is just to be able to cut the casing 10 or the casing 30 of the washing machine . In addition, since a rigid object such as the motor 16 is not cut, blade spilling does not occur and the life of the blade is extended. In addition, cutting can be performed with a blade of a small-sized and low-power cutting machine .

The above-mentioned cutting by the cutting machine causes crushed pieces of the casing 10 or the casing 30 to scatter.
It is a small piece of thin iron plate that can be disposed of with the subsequent resin.

6. Subsequent Disposal As described above, the two-tub washing machine 1 is divided into a bottom plate 19 to which the motor 16 is fixed, a bottom plate 19 to which the motor 18 is fixed, and an upper part of the housing 10. Thereafter, the bottom plate 19 to which the motor 16 is attached and the bottom plate 19 to which the motor 18 is attached are separated from the bottom plate 19 by removing the motor 16 and the motor 18, respectively.
For the motor 6 and the motor 18, disassembly of the motor / reducer, collection of the condenser, collection of the casing, and the like are performed. Thereafter, the casing 10 is subjected to a crushing process. The one-tub type (fully automatic) washing machine 3 is also post-processed similarly to the two-tub type washing machine 1. Before disassembly and crushing of the single-tub type (fully automatic) washing machine 3, the salt water stored as a balancer is collected. As described above, since the same material is disposed, the classification is easy, the disposal can be appropriately performed, and the recycling can be utilized.

For example, other width measuring means can be used instead of the wire type linear encoder 107 as the means for measuring the width of the washing machine to be dismantled in FIG. Similarly, it is possible to use other back Gyohaka constant means instead of the ultrasonic displacement sensor 108 in FIG. As the measuring means itself for measuring the width and depth, use various well-known and commonly used means.
Can be. Similarly, the circular metal cutting saw 303 of the bottom frame cutting device 300 in FIG. 5 can be replaced with another alternative means. Ultrasonic sensor 407 and lifting member 4 in FIG.
The configuration of 05 can be replaced with alternative means as appropriate. The various means in FIG. 7 can be replaced with other various alternative means.
