Description

[Technical Field]

[0001] The present invention relates to a method for dismantling and shredding automobiles, which is capable of efficiently recovering reusable resources when dismantling end-of-life automobiles. [Background technology]

[0002] Traditionally, useful metals and parts have been recovered and reused from end-of-life vehicles during the dismantling and crushing process. In recent years, various efforts have been made to recover useful materials such as metals and parts contained in end-of-life vehicles without discarding them as much as possible. For example, in the dismantling of a vehicle disclosed in Patent Document 1, the windshield of the end-of-life vehicle is removed from the body of the end-of-life vehicle, the roof of the end-of-life vehicle is separated from the body, and then the interior plastic parts are removed from the cabin of the body, and the roof plastic parts are also removed from the roof, resulting in a dismantled vehicle. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-64503 Summary of the Invention [Problem to be solved by the invention]

[0004] Dismantled automobiles from which the windshields and plastic parts have been removed as described above are generally taken over by a shredding company, where they are finely shredded using a shredder. Metals are then sorted through a range of processes, including magnetic sorting and wind sorting, and non-ferrous metals, plastics, copper wire, and other valuable materials are then manually recovered from the remaining shredded material.

[0005] However, when dismantling and shredding end-of-life vehicles in the above-mentioned order, it is necessary to shred the dismantled vehicles, which still have many of the various metals and parts attached, which necessitates the use of larger shredders, which requires a large working space to accommodate the equipment, and which results in the problem of extremely large energy consumption per dismantled vehicle.Furthermore, after dismantling a dismantled vehicle, useful materials and non-useful materials are mixed in a complex manner in the shredded material, and useful materials cannot be recovered in small quantities without undergoing a complex sorting process, which requires manual sorting by workers, which not only makes it difficult to recover useful materials efficiently but also increases costs.

[0006] The present invention has been made in view of the above points, and its object is to provide a low-cost automobile dismantling and shredding method that allows work to be done in a small space, reduces energy consumption during work, and allows useful materials to be recovered efficiently. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention is characterized in that an automobile dismantling machine is used to tear off everything that can be torn off or removed from an end-of-life automobile, or after removal, only the remaining material that remains after the work is crushed.

[0008] Specifically, the following measures were taken regarding automobile dismantling and shredding methods, which involve dismantling and shredding end-of-life automobiles to extract useful materials.

[0009] That is, the automobile dismantling and crushing method according to the first invention includes a roof separation process in which, after separating the roof portion of the end-of-life automobile from the main body portion of the end-of-life automobile, roof interior parts are peeled off from the roof panel portion of the roof portion, and then roof remaining parts excluding the resin panel portion are removed from the roof interior parts using an automobile dismantling machine; and a second process in which, after removing the seat portion from the main body portion, the seat electrical parts and seat resin parts are peeled off from the seat frame portion of the seat portion, and then the remaining parts are removed from the seat frame portion. a sheet removal process in which the automobile dismantling machine performs the operations of removing sheet residue; a body upper dismantling process in which the automobile dismantling machine performs the operations of peeling off interior vehicle parts from the body, then peeling off interior electrical components and interior plastic parts from the body and the interior vehicle parts, and then removing upper body residue from the upper region of the body and the interior vehicle parts; and the operations of turning the body over, removing suspension parts, and then removing lower body residue from the underside of the body and the suspension parts. a body lower side dismantling process performed by the automobile dismantling machine; an exterior resin part removal process in which the automobile dismantling machine performs the operations of removing exterior resin parts of the body part and then removing remains associated with the exterior resin parts located between the exterior resin parts and the body part; a heat exchanger removal process in which the automobile dismantling machine performs the operations of removing a heat exchanger from the body part and then removing remains associated with the heat exchanger located between the heat exchanger and the body part; and a glass member removed from the body part and then removing remains associated with the heat exchanger located between the glass member and the body part. and a glass member removal process in which the automobile dismantling machine performs each of the operations of removing the glass member-associated remains and placing them in the car body. After each of the operations is performed, the roof remains, the sheet remains, the upper body remains, the lower body remains, the exterior resin part-associated remains, the heat exchanger-associated remains, and the glass member-associated remains are collectively formed into a dismantling remainder, and then the dismantling remainder is crushed by a crusher having an output of 50 horsepower or less to obtain crushed material, and then metal objects are removed from the crushed material using a magnetic separator. The automobile dismantling and shredding method configured in this way operates so that the only equipment required for removing dismantling residues in each process of dismantling an end-of-life vehicle is the automobile dismantling machine. It also operates so that only the dismantling residues remaining after most of the useful materials have been removed from the end-of-life vehicle are shredded by the shredder. Furthermore, it also operates so that the need for sorting work through complex sorting processes and manual sorting work by workers is eliminated.

[0010] The automobile dismantling and shredding method according to the second invention is characterized in that, in the first invention, the content of metal objects in the dismantling residue when crushed by the crusher is 1% or less. In the automobile dismantling and crushing method configured in this manner, when the dismantling residue is crushed, the load applied to the crusher by the metal objects contained in the dismantling residue is almost eliminated. [Effects of the Invention]

[0011] In the automobile dismantling and shredding method of the first invention, the only equipment required for each process of dismantling an end-of-life automobile is an automobile dismantling machine: separating a portion of the body, peeling or removing each part, equipment, and member from the body, and removing dismantling residue from between these parts, equipment, and members and the body. Therefore, because less equipment is required, each process can be performed in a smaller space, and the energy consumed for each dismantling process can be reduced. Furthermore, because only the dismantling residue after removing most of the useful material from the end-of-life automobile is shredded by the shredder, the energy consumed for the shredding process can also be reduced. Furthermore, since the complex sorting process required in conventional technology is no longer necessary, and manual sorting by workers is no longer required, the costs of dismantling and shredding can be kept low.

[0012] In the automobile dismantling and shredding method of the second invention, when shredding the dismantling residue, the load on the shredder due to the metal objects contained in the dismantling residue is almost eliminated. Therefore, the specifications of the shredder can be kept low, achieving both low equipment costs and space savings in the work area. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following description of the preferred embodiment of the present invention is merely exemplary in nature.

[0015] 1 and 2 show an automobile dismantling and shredding system 1 used when carrying out an automobile dismantling and shredding method according to an embodiment of the present invention. This automobile dismantling and shredding system 1 is composed of an automobile dismantling machine 2, a press machine 3, a shredder 4, and a magnetic separator 5, and is configured to dismantle and shred an end-of-life automobile 10. As pre-processing for the dismantling work, the tires and batteries of this end-of-life automobile 10 have been removed, and waste oil and waste liquid have been removed. In addition, the airbags have either been deployed on the vehicle or removed and collected. Furthermore, the engine of the end-of-life automobile 10 has been unloaded.

[0016] The automobile dismantling machine 2 comprises a crawler-type lower running body 6 and a shovel body 7 attached above the lower running body 6 via a swivel mechanism, and the shovel body 7 is rotatable around a rotation axis extending in the vertical direction.

[0017] A box-shaped cab 7A for protecting the operator of the automobile dismantling machine 2 is provided on one side in the width direction of the shovel body 7.

[0018] On the other hand, a demolition attachment 7B is provided on the other widthwise side of the shovel body 7, and this demolition attachment 7B includes a boom 7a, an arm 7b, and a crusher 7c in this order from the base end side.

[0019] The crusher 7c is shaped like scissors and is capable of cutting the frame portion of the used automobile 10, and of clamping and peeling or removing useful materials contained in the used automobile 10 from the main body portion 10b (white body) of the used automobile 10.

[0020] For example, the crusher 7c is designed to separate the roof portion 10a of the end-of-life vehicle 10 from the main body portion 10b by cutting the pillar portion of the end-of-life vehicle 10. The crusher 7c is also designed to clamp and pull off roof interior parts 11 (such as molded ceiling materials with wire harnesses, resin piping, etc.) from the roof panel portion of the separated roof portion 10a. Furthermore, the crusher 7c is designed to clamp and remove roof remnants X1, excluding the resin panel portion (the molded ceiling material and pillar portion), from the roof interior part 11. The roof remnants X1 are, for example, soundproofing or sound-absorbing materials made of urethane, and do not include scrap iron, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0021] Furthermore, for example, the crusher 7c is configured to pinch and remove the seat component 10c from the main body 10b. The crusher 7c is also configured to pinch and peel off the seat electrical components 12 (such as wire harnesses) and the seat resin parts 13 from the seat frame of the removed seat component 10c. The crusher 7c is also configured to pinch and remove seat residue X2 from the seat frame. Note that the seat residue X2 is, for example, a cushioning material made of urethane or a seat cover made of leather, but does not include iron scraps, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0022] The crusher 7c is also configured to clamp and remove interior vehicle components 10d (e.g., dashboard components and center console components) from the main body 10b. The crusher 7c is also configured to clamp and remove interior electrical components 14 (e.g., wire harnesses) and interior plastic parts 15 (e.g., plastic panels such as dashboard panels and center console panels) from the removed interior vehicle components 10d. The crusher 7c is also configured to clamp and remove upper body remaining material X3 from the upper region of the main body 10b and the interior vehicle components 10d. The upper body remaining material X3 is, for example, soundproofing or sound-absorbing material made of urethane, and does not include iron scrap, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0023] The crusher 7c is also designed to clamp and remove underbody parts 10e (e.g., brakes, suspensions, dampers, mufflers, etc.) from the inverted main body 10b. The crusher 7c is also designed to clamp and remove underbody residue X4 from the removed underbody parts 10e and the lower area of ​​the main body 10b. Note that the underbody residue X4 is, for example, vibration-proof rubber attached to dampers, mufflers, etc., and does not include iron scraps, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0024] The crusher 7c is also designed to clamp and remove the exterior resin part 10f (e.g., a bumper or side sill cover) from the main body 10b. The crusher 7c is also designed to clamp and remove the exterior resin part associated remains X5 located between the removed exterior resin part 10f and the main body 10b. Note that the exterior resin part associated remains X5 are, for example, plastic bumper mounting clips and vibration-isolating rubber, and do not include scrap iron, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0025] The crusher 7c is also designed to clamp and remove the heat exchanger 10g (radiator, condenser) from the main body 10b. The crusher 7c is also designed to clamp and remove the heat exchanger-related remains X6 located between the removed heat exchanger 10g and the main body 10b. The heat exchanger-related remains X6 are, for example, heat-resistant rubber tubes and grommets, and do not include scrap iron, non-ferrous metals, useful plastics, electrical components, wire harnesses, etc.

[0026] The crusher 7c is also designed to clamp and remove the glass member 10h (such as a window glass or door glass) from the main body 10b. It is also designed to clamp and remove glass-member-associated remains X7 located between the glass member 10h and the main body 10b. Glass-member-associated remains X7 include, for example, weather strips and resin mounting clips, but excludes iron scrap, non-ferrous metals, useful plastics, electrical components, wire harnesses, and the like.

[0027] As shown in Figure 2, the press machine 3 has a horizontally wide pit 3a that opens into the floor surface, a press plate 3b that has a shape corresponding to this pit 3a, and a hydraulic cylinder 3c that is arranged around the pit 3a.

[0028] The press plate 3b can rotate up and down around the end of the hydraulic cylinder 3c as a fulcrum. The hydraulic cylinder 3c has a rod 3d that extends and contracts obliquely downward, and the tip of the rod 3d is connected to the surface of the press plate 3b.

[0029] When the rod portion 3d of the hydraulic cylinder 3c is contracted, the press plate 3b rotates upward and jumps out of the pit 3a, opening the pit 3a, and when the rod portion 3d is extended, the press plate 3b rotates downward and enters the pit 3a.

[0030] Then, roof residue X1, sheet residue X2, upper body residue X3, lower body residue X4, exterior resin part-related residue X5, heat exchanger-related residue X6, and glass member-related residue X7 are thrown into the open pit 3a, and the press plate 3b is rotated downward to enter the pit 3a, whereby the residue X1 to X7 are compressed between the bottom of the pit 3a and the press plate 3b and collectively formed into dismantling residue X. For convenience, only X1 to X3 of the residue X1 to X7 thrown into the pit 3a are shown in FIG. 2. In addition, dismantling residue X contains small metal objects such as nuts and washers, the content of which is less than 1%.

[0031] The crusher 4 is a so-called uniaxial type, and as shown in Figure 2, it comprises a main body case 4a that opens at the top and bottom, a hopper 4b attached to the top of the main body case 4a, and a stand 4c that supports the main body case 4a. A drive motor (not shown) that rotates the rotary blades is housed inside the main body case 4a.

[0032] This crusher 4 has an output of 50 horsepower or less, and crushes the demolition residue X fed into the hopper 4b using rotating blades inside the main case 4a, and discharges the crushed material Z below the main case 4a.

[0033] The magnetic separator 5 separates crushed materials Z, which are fed into a case from above, into metal materials Z1 and non-metal materials Z2 by the rotation of a drum 5a containing a magnet. This non-metallic object Z2 is ASR (Automobile Shredder Residue) and is then sent to the automobile manufacturer.

[0056] Step S250 is a process of removing the exterior resin part 10f from the main body 10b of the end-of-life automobile 10. Specifically, processing of the exterior resin part 10f and its surroundings is carried out in accordance with the procedure of the flowchart shown in FIG.

[0057] That is, first, in S251, the crusher 7c of the automobile dismantling machine 2 is operated to remove the exterior resin parts 10f from the main body 10b, and then the process proceeds to step S252.

[0058] In step S252, the worker operates the crusher 7c of the automobile dismantling machine 2 to clamp and remove the exterior resin part associated remnants X5 located between the exterior resin part 10f and the main body 10b, and once all of the exterior resin part associated remnants X5 located between the exterior resin part 10f and the main body 10b have been removed, the process proceeds to step S260 in Figure 5.

[0059] Step S260 is a process of removing the heat exchanger 10g from the main body 10b of the end-of-life automobile 10. Specifically, processing around the heat exchanger 10g is carried out in accordance with the procedure of the flowchart shown in FIG.

[0060] That is, first, in S261, the crusher 7c of the automobile dismantling machine 2 is operated to remove the heat exchanger 10g from the main body 10b, and then the process proceeds to step S262.

[0061] In step S262, the worker operates the crusher 7c of the automobile dismantling machine 2 to clamp and remove the heat exchanger-related remains X6 located between the heat exchanger 10g and the main body 10b, and once all of the heat exchanger-related remains X6 located between the heat exchanger 10g and the main body 10b have been removed, the process proceeds to step S270 in Figure 5.

[0062] Step S270 is a process of removing the glass member 10h from the main body 10b of the end-of-life automobile 10. Specifically, processing around the glass member 10h is carried out in accordance with the procedure of the flowchart shown in FIG.

[0063] That is, first, in S271, the crusher 7c of the automobile dismantling machine 2 is operated to remove the glass member 10h from the main body 10b, and then the process proceeds to step S272.

[0064] In step S272, the worker operates the crusher 7c of the automobile dismantling machine 2 to clamp and remove the glass element-associated remains X7 located between the glass element 10h and the main body portion 10b, and once all of the glass element-associated remains X7 located between the glass element 10h and the main body portion 10b have been removed, the process proceeds to step S300 in Figure 3.

[0065] In step S300, the roof remains X1, sheet remains X2, upper body remains X3, lower body remains X4, exterior resin part associated remains X5, heat exchanger associated remains X6, and glass member associated remains X7, which were removed in step S200, are crushed. Specifically, the crushing operation is performed according to the flowchart shown in FIG.

[0066] Step S310 is a process of combining roof remnants X1, sheet remnants X2, upper body remnants X3, lower body remnants X4, exterior plastic part associated remnants X5, heat exchanger associated remnants X6, and glass component associated remnants X7 into dismantling remnants X.

[0067] That is, first, in step S310, the worker operates the press 3 to rotate the press plate 3b upward to open the pit 3a, then throws the roof remnants X1, sheet remnants X2, upper body remnants X3, lower body remnants X4, exterior resin part associated remnants X5, heat exchanger associated remnants X6, and glass member associated remnants X7 into the pit 3a, and then rotates the press plate 3b downward. The remnants X1 to X7 are then compressed between the bottom of the pit 3a and the press plate 3b and combined into dismantling remnants X, and the process proceeds to step S320.

[0068] Step S320 is a process of crushing the dismantling residue X. That is, in step S320, the operator puts the dismantling residue X into the hopper 4b of the crusher 4, and then rotates a rotary blade (not shown) located inside the main body case 4a of the crusher 4. Then, the dismantling residue X is crushed and crushed material Z is discharged below the main body case 4a, and the process proceeds to step S330.

[0069] Step S330 is a process of magnetically separating the crushed objects Z. That is, in step S330, the worker puts the crushed objects Z into the magnetic separator 5 from above, and then rotates the drum 5a located inside the magnetic separator 5. Then, the crushed objects Z are magnetically separated and sorted into metal objects Z1 and non-metal objects Z2, and the work in the automobile dismantling and crushing system 1 is completed.

[0070] As described above, according to the embodiment of the present invention, in each process of dismantling an end-of-life vehicle 10, the only equipment required for the work of partially separating the main body 10b, the work of peeling off or removing each part, device, and member from the main body 10b, and the work of removing the dismantling residue X from between each of these parts, devices, and members and the main body 10b is the automobile dismantling machine 2. Therefore, because less equipment is used, each work can be performed in a smaller space, and the energy consumed in each dismantling work can be reduced.

[0071] In addition, since only the dismantling residue X after most of the useful materials have been removed from the end-of-life vehicles 10 is crushed by the crusher 4, the energy consumed in the crushing process can also be reduced. Furthermore, since there is no need for the complicated sorting process used in the prior art, and there is no need for manual sorting by workers, the costs required for dismantling and crushing can be kept low.

[0072] Furthermore, because the content of metal objects Z1 contained in the demolition residue X is 1% or less, when the demolition residue X is crushed, the load on the crusher 4 due to the metal objects Z1 contained in the demolition residue X is almost eliminated. Therefore, the specifications of the crusher 4 can be kept low, achieving both low equipment costs and space savings in the work area.

[0073] In the embodiment of the present invention, the exterior resin part removal process, the heat exchanger removal process, and the glass member removal process are performed after the lower body dismantling process, but they do not necessarily have to be performed after the lower body dismantling process, and may be performed, for example, before the roof separation process.

[0074] Furthermore, in the embodiment of the present invention, the crusher 4 is a single-shaft type, but if the output is 50 horsepower or less, a double-shaft type crusher 4 may be used to crush the dismantling residue X.

[0075] The main body 10b from which the useful materials and dismantling residue X have been removed is delivered to an electric furnace manufacturer as scrap iron. Non-ferrous metals generated during dismantling are delivered to a refining manufacturer. Furthermore, plastic parts such as bumpers are delivered to a plastic manufacturer.
