Description

  The present invention relates to a recovery processing method and a recovery processing apparatus for mechanically recovering a rare metal (rare metal) used in waste home appliances and the like.

  Conventionally, used products such as hard disk drives for personal computers and portable small-sized household appliances such as mobile phones have been recovered only for some metals such as copper and precious metals, but are used in these small-sized household appliances. Small motors and other rare metals such as neodymium and rare earth (rare metals do not include precious metals other than platinum and palladium. In addition, the rare metals and precious metals are collectively referred to in this specification and claims) In recent years, there has been a movement to collect used products such as those mentioned above, select rare metals from them, collect them, and recycle them for effective use of resources. It is growing.

  As a method for recovering rare metals, etc. from used products such as waste small household appliances (also referred to as “objects to be processed” in this specification and claims), A method of disassembling and collecting main parts, or putting the entire used product into a pulverizer and making it into a powder form is considered. However, in the former case, it is difficult to establish economically because labor costs increase and it is difficult to establish a large-scale business. In the latter case, it is possible to sort plastic and metal, or sort iron and aluminum for collection. Moreover, it is also possible to collect | recover copper and a noble metal from the mixed metal containing copper by nonferrous smelting. However, since non-ferrous smelting can recover only precious metals and some rare metals, it is necessary to select many rare metals in advance at the particle stage. However, after the entire workpiece is crushed, it is recovered by non-ferrous smelting. No technology has been established for sorting precious metals, some rare metals, and many rare metals that cannot be recovered by non-ferrous smelting.

  In addition, as an example of the use of the rare metal, it is often the case that the rare earth magnet exists inside the object to be processed. Specifically, it is used for a voice coil motor, a digital camera motor, a mobile phone vibrator, and the like in a hard disk drive used in a personal computer. When products containing such rare earth magnets are pulverized, the magnets are strongly magnetized in the pulverizer, causing clogging of the crusher screen and causing troubles.

  Therefore, at present, it is difficult to collect rare metals and the like from a total number of objects to be processed such as small home appliances on a large scale and economically, and it is hardly performed.

  In addition, as a prior art which is going to isolate | separate and collect metals etc. from a to-be-processed object, there exists an apparatus which can disassemble and isolate | separate mechanical apparatuses, such as a compressor, for every structural component, for example. In this device, the internal structure in the outer casing is visualized by an internal visualization means such as an X-ray imaging device in the stage before disassembly, and the cutting position of the outer casing is determined corresponding to the internal structure in the visualized state. The position is cut and the internal structural parts are disassembled and separated (see, for example, Patent Document 1).

  In addition, as another prior art, in order to sever the metal lump of valuable resources from waste home appliances, the type of waste home appliances is identified by an identification device using an optical sensor, the cutting position is determined, and the cutting is performed. In some cases, the position of the cutting device and the stopper is controlled so as to be in the position, and the metal lump is cut and separated from the waste home appliances in contact with the stopper with the cutting device (for example, see Patent Document 2). ).

  Furthermore, as another prior art, as a method of disassembling a flat panel display in which a face plate and a rear plate are joined with a lead-containing frit glass through a frame, the model is identified by a sensor, and the database of the model is used. On the basis of the above, there is a part in which a part including the face plate and a part including the rear plate are separated and processed in a liquid (for example, see Patent Document 3).

  As another prior art, in order to easily dismantle machine waste with an industrial machine, the fastening member head of the machine member to be discarded is colored with a color different from that of the component member, and the head position of the fastening member is obtained by an image camera. In other cases, the fastening member is removed by an industrial machine, the mechanical member is disassembled, and the material is sorted for each material after disassembly (see, for example, Patent Document 4).

JP 2000-197870 A Japanese Patent Laid-Open No. 9-300127 JP 2000-310955 A JP 2001-276793 A

  However, the technique described in Patent Document 1 is to disassemble and separate internal structural components by cutting at a cutting position determined by the internal structure visualized based on X-ray information. The described technique is to determine the cutting position by identifying the model of the object to be processed based on sensor information such as an optical sensor, and the technique described in the above-mentioned patent document 4 uses a fastening member colored in advance. It is recognized by an image camera and dismantled by an industrial machine. It does not identify and selectively collect rare metal parts present in a part of the object to be processed. Rare metals contained in the object to be processed are not collected. It cannot be recovered and recycled efficiently.

  In addition, for example, even when the rare metal is a rare earth magnet, the portion cannot be identified. If the rare earth magnet separated from the object to be processed is pulverized as described above, it is difficult to collect the rare earth magnet. Magnetic contact with the metal part of the device causes trouble.

  Therefore, the present invention has an object to provide a rare metal recovery processing method and a recovery processing apparatus capable of efficiently recovering rare metals such as valuable rare metals from an object to be processed by a mechanical technique and efficiently recycling them. To do.

  In order to achieve the above object, a rare metal recovery processing method of the present invention is a processing method for recovering a rare metal portion present in a part of an object to be processed. After identifying the rare metal portion in the object to be processed by the identification sensor, and positioning the identified rare metal portion at the cutting position of the cutting machine, the rare metal portion is cut by the cutting machine, The cut-out rare metal part and the other part are separately carried out and processed. As a result, the position information of the workpiece to be carried in and the rare metal portion in the workpiece are identified by the identification sensor, and the rare metal portion is selected by a cutting machine that is a mechanical method based on the information. After cutting away valuable rare metal parts from the object to be processed, the rare metal parts and other parts that were cut off are processed separately. Other parts can be crushed to collect other metals and the like, and each can be collected separately by a suitable method, so that rare metals can be efficiently recycled.

  In addition, the workpieces to be carried in may be sorted in advance for each type of workpiece, and the sorted workpieces may be continuously processed at a predetermined interval. If it does in this way, according to the kind, the rare metal part which exists in the same position can be efficiently cut out and collect | recovered.

  Further, the objects to be processed of the selected types may be further selected for each similar shape, and the objects to be processed selected for each similar shape may be continuously carried in the same direction. In this way, since the workpieces having substantially the same shape are continuously processed, the cutting accuracy can be increased.

  Further, the rare metal part has a rare earth magnet, the rare earth magnet part is identified by a magnetic sensor, the rare earth magnet part is cut by a cutting machine, and then the cut rare earth magnet part is coated with a nonmagnetic material. You may make it do. If it does in this way, it can carry out preventing the rare earth magnet part cut out from the to-be-processed object from magnetizing to a metal part.

  Further, the object to be processed is a hard disk drive, the hard disk drive is loaded in a predetermined direction, and the rare metal portion of the loaded hard disk drive is identified by an identification sensor having a magnetic sensor and a position sensor. Good. In this way, the rare metal portion can be efficiently recovered from the hard disk drive that is relatively easy to identify the rare metal portion.

  On the other hand, a rare metal recovery processing apparatus of the present invention is a rare metal recovery processing apparatus that realizes one of the above rare metal recovery processing methods, a position sensor that obtains transport position information of a loaded object, An identification sensor for identifying a rare metal part in the processing object, a transport unit for conveying the rare metal part identified by the identification sensor to a cutting position of a cutting machine, and a cutting for cutting off the rare metal part identified by the identification sensor And a carry-out part for carrying out the rare metal part cut out by the cutting machine and the other part separately. The “cutting machine” in the document of this specification and claims refers to a machine provided with a cutting blade such as a punch for punching a predetermined range. Thus, after position information such as the posture of the workpiece to be loaded is identified by the position sensor, the rare metal portion in the workpiece is identified in advance by an identification sensor (for example, a magnetic sensor, an image sensor, a combination of these sensors, etc.) ) To identify where the rare metal-containing portion exists in the workpiece, and then cut the rare metal-containing portion into the cutting position of the cutting machine (for example, the cutting position with a punch, cutter, etc.) And cut it with a cutting machine, and carry out the cut part and the other part separately for processing, so the recovery process of the rare metal part and the recovery process of the other part are efficiently performed, Rare metals can be recycled efficiently.

  The cutting machine may include a nonmagnetic metal cutting blade. If it does in this way, even if a rare metal content part is a part containing a rare earth magnet, it can be cut out stably, without magnetizing to a cutting blade.

  Furthermore, it may have a means for preliminarily sorting the object to be loaded for each type of object to be treated, and may further comprise a loading machine for continuously loading the object to be treated sorted by the sorting means at a predetermined interval. . If it does in this way, according to the kind, the rare metal part which exists in the same position can be efficiently cut out and collect | recovered.

  Further, there is provided a loading machine that further includes a means for sorting the sorted objects to be processed for each similar shape, and continuously loads the sorted objects to be processed for each similar shape in the same direction. You may have. In this way, since the workpieces having substantially the same shape are continuously processed, the cutting accuracy can be increased.

  Further, the object to be processed is a hard disk drive, a transport means for transporting the hard disk drive, a magnetic sensor for detecting a rare earth magnet portion of the hard disk drive to be transported, and a cutting machine for detecting the detected position of the hard disk drive. There may be provided a position adjusting means for conveying to the position and a carry-out section for carrying out the rare-earth magnet part and the other part separately after cutting the rare-earth magnet part of the hard disk drive by the cutting machine. In this way, after the hard disk drives having substantially the same external shape are continuously loaded and the rare earth magnet portion, which is a rare metal portion, is efficiently cut out, the rare earth magnet portion and the other portion are separately unloaded and thereafter Thus, the rare earth magnet portion can be efficiently recovered.

  According to the present invention, a valuable rare metal portion is cut out from a workpiece by a mechanical method, and the rare metal portion and another portion are separately collected and processed, so that the entire workpiece can be efficiently recycled. Is possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a 3.5-inch hard disk drive (hereinafter simply referred to as “HDD”) used in a personal computer or the like will be described as an example of the object to be processed. This 3.5-inch HDD has an outer size determined by the standard, and has an actuator-controlled voice coil motor (rare earth magnet portion; rare metal portion) that moves the magnetic head for writing / reading on the rotating disk. It is provided in the place. A rare earth magnet containing a rare metal is provided in the voice coil motor. In the following description, the left side in the state shown in FIG. 2 is the rear side, the right side is the front side, the lower side of the page is the front side, and the upper side of the page is the back side.

  1A to 1D show a pattern in which a rare earth magnet portion 11 (shaded portion) provided with an internal rare earth magnet 12 is located in a plan view when the longitudinal direction of the HDD 10 is directed in the left-right direction. Show. In the state in which the longitudinal direction of the HDD 10 is directed in the left-right direction, there is a state in which the HDD 10 is disposed in the front-rear reverse direction and the left-right reverse direction. (The hatched portion shown in the figure).

  As shown in FIG. 2, in the rare metal recovery processing apparatus 20 of this embodiment, the HDD 10 carried on the stage 21 is conveyed on the stage 21 from the left to the right in this example. The In the figure, the states of a plurality of positions in the process of transporting the HDD 10 are indicated by solid lines, and (1) to (4) are given to the respective positions.

  As for the conveyance of the HDD 10, the HDD 10 carried into the reference position (1) of the stage 21 is pushed at the rear end by the HDD conveyance slide bar 22 which is a conveyance unit and conveyance means, and the magnetic sensors 31, 32 and the position sensor 33, 34 to the detection position (2) where the identification sensor 30 is provided. The identification sensor 30 of this example includes magnetic sensors 31 and 32 that detect the weak magnetism of the surface leaking from the rare earth magnet 12 of the HDD 10, and the HDD conveyance slide bar 22 when the magnetic sensors 31 and 32 detect magnetism. Position sensors 33 and 34 for detecting the position, and the magnetic sensor 31 and 32 detects which of the left and right positions of the HDD 10 the magnetism is detected by the position sensors 33 and 34 of the HDD transport slide bar 22. The position of the rare earth magnet portion 11 is identified from the combination of the position.

  FIG. 3 shows combinations of detection conditions by the magnetic sensors 31 and 32 and the position sensors 33 and 34 and the position of the rare earth magnet 12 of the HDD 10. As shown in the figure, in the above combination, when the magnetic sensor 31 detects magnetism, the position sensor 34 detects the HDD transport slide bar 22, the rare earth magnet 12 is in the position (A), and when the magnetic sensor 32 detects magnetism, the position is detected. When the sensor 34 detects the HDD transport slide bar 22, the rare earth magnet 12 is in the (B) position, and when the position sensor 33 detects the HDD transport slide bar 22 when the magnetic sensor 31 detects magnetism, the rare earth magnet 12 is in the (C) position. When the position sensor 33 detects the HDD transport slide bar 22 when the magnetic sensor 32 detects magnetism, the rare earth magnet 12 is in the (D) position, so that the HDD 10 is crossed over the magnetic sensors 31 and 32 and the magnetic sensor 31 is moved. , 32 from the two sets of information on the front, back, near side, and back side, the rare earth in the HDD 10 is detected. And so as to identify which one of the positions of the four patterns where the position of the magnet 12 can occur.

  In the magnetic detection by the magnetic sensors 31 and 32, the HDD 10 is formed in a rectangular shape in plan view as shown in FIG. 4A, and the surface of the HDD 10 is scanned with a gauss meter as shown in FIG. 4B. This is based on the fact that the magnetic flux density distribution comes to be illustrated. As shown in the figure, in this example, the magnetism of 1 mT to 3 mT is detected at only one of the four corners, and the HDD 10 in the state shown in the figure can identify that the rare earth magnet 12 is stored in the lower left. .

  In this way, by reading the weak magnetism leaking to the surface of the HDD 10 and detecting the transport position of the HDD 10 at that time, it is possible to identify where the rare earth magnets 12 are present at the four corners of the HDD 10 in a non-destructive manner. Yes.

  As the magnetic sensors 31 and 32, for example, Hall element type sensors capable of detecting about 1 mT to 5 mT are used. For example, only whether or not a magnetic field exceeding a threshold is detected is detected. Good. The magnetic sensitivity of the magnetic sensors 31 and 32 may be set according to the shape of the object to be processed, the size of the rare earth magnet 12, the arrangement relationship, and the like.

  Then, as described above, the HDD 10 in which the rare earth magnet portion 11 is detected by the magnetic sensors 31 and 32 and the position sensors 33 and 34 has the nonmagnetic blade punch 41 (cutting blade) at the cutting position (3) by the cutting machine 40. After being transported to the position (4) just below and the rare earth magnet portion 11 cut off, the rare earth magnet portion 11 and other portions are separately carried out. Details of this will be described below.

  Hereinafter, the process of cutting and collecting the rare earth magnet portion 11 of the HDD 10 by the rare metal recovery processing device 20 will be described in detail with reference to FIG. In the following description, a method for efficiently cutting and processing a rare earth magnet portion with the processing time for checking the rare earth magnet portion as a minimum time will be described. In this example, the case where the rare earth magnet 12 is located at the position (D) will be described as an example.

  The HDD 10 carried into the reference position (1) in FIG. 2 passes through the detection position (2) and is cut to the right of the drawing position (3) (in FIG. 2, two parts of the moved HDD 10 are two points. It is conveyed by the HDD conveyance slide bar 22 until it is shown by a chain line.

  When the HDD 10 transported between these positions reaches a position above both the magnetic sensors 31 and 32, the magnetism of the rare earth magnet 12 is detected by the magnetic sensors 31 and 32. Which one of the magnetic sensors 31 and 32 detects the magnetism of the rare earth magnet 12 is detected to determine whether the rare earth magnet 12 is present on the front side or the rear side of the HDD 10.

  Then, it is specified whether the position of the rare earth magnet 12 is located at the front part or the rear part of the HDD 10 depending on which of the position sensors 33 and 34 detects that the HDD transport slide bar 22 crosses when the magnetism is detected. Is done.

  That is, by sending the rectangular HDD 10 in the longitudinal direction, depending on the combination of which of the magnetic sensors 31 and 32 has detected magnetism and the position of the position sensors 33 and 34 when the magnetism is detected, FIG. As shown in FIG. 5, it is detected whether the rare earth magnet 12 is present on the front side or the rear side of the HDD 10 either on the front side or on the rear side.

  Thereafter, when the HDD 10 is sent to the cut position (3) and the HDD transport slide bar 22 passes the position sensor reset 35, the identification sensor 30 prepares for the detection of the next rare earth magnet portion 11 of the HDD 10 and the rare earth of the HDD 10. The magnet part detection position information is reset. As will be described later, the HDD transport slide bar 22 recovers the other part of the HDD 10 from which the rare earth magnet portion 11 has been cut out to the body recovery pocket 24 which is a carry-out part, and then returns to the reference position (1) and continues to the next. This is provided for detecting the position of the rare earth magnet 12 of the HDD 10.

  On the other hand, in the HDD 10 of this example, since the rare earth magnet portion 11 is at the position (D), after being sent to the cut position (3), the HDD 10 is cut by the HDD break position slide bar 23 which is a transport unit and position adjusting means. It is moved to the back so that the rare earth magnet portion 11 is located at a position (4) just below the nonmagnetic blade punch 41 (cutting blade) of the machine 40 (FIG. 7).

  Further, the movement of the HDD 10 by the HDD transport slide bar 22 and the HDD breaking position slide bar 23 is such that the rare earth magnet portion 11 is arranged directly below the nonmagnetic blade punch 41 according to the positions of the identified four patterns. Linked operation is performed. The HDD destruction position slide bar 23 quickly returns to the original position after transferring the HDD 10 to the cut position (4) (position indicated by a two-dot chain line).

  In this embodiment, an example in which the rare earth magnet 12 is located at the (D) position of the HDD 10 is shown. However, when the rare earth magnet 12 is located at other (A) and (C) positions, the HDD transport slide bar is shown. When the HDD 10 is sent to the cut position (4) by 22, the rare earth magnet portion 11 of the HDD 10 is positioned directly below the nonmagnetic blade punch 41 without being moved by the HDD breaking position slide bar 23.

  Then, the rare earth magnet portion is cut by the nonmagnetic blade punch 41 of the cutting machine 40. The rare-earth magnet portion is cut off by the nonmagnetic blade punch 41 by punching from the upper side to the lower side of the drawing to cut out the four sides of the rare-earth magnet portion 11 and carry it out downward. In this way, the rare earth magnet portion (voice coil motor portion) 11 cut from the HDD 10 by the nonmagnetic blade punch 41 is dropped and collected through a drop hole (not shown).

  The other part of the HDD 10 from which the rare earth magnet part 11 has been cut off is collected in the body collection pocket 24 by the HDD transport slide bar 22 and carried out of the rare metal collection processing apparatus 20 separately from the rare earth magnet part.

  In this way, a method of cutting the valuable rare earth magnet portion 11 (rare metal portion) from the HDD 10 (object to be processed) and separately collecting the rare earth magnet portion 11 and the other portion is a rare metal recovery processing apparatus. 20 is a rare metal recovery method.

  On the other hand, as shown in FIG. 5, in the case of the HDD 10, the rare earth magnet 12 provided in the voice coil motor portion is attached with the rare earth magnet 12 in close contact with the yoke 15, as shown in FIG. Therefore, as shown in FIG. 5, the shape of the nonmagnetic blade punch 41 is determined so that the rare earth magnet portion is punched by the nonmagnetic blade punch 41, and the mounting portion of the yoke 15 that houses the rare earth magnet 12 is cut. The adhesion strength between the yoke 15 and the rare earth magnet 12 can be weakened by punching out at the portion, and the yoke 15 can be deformed by the pushing of the nonmagnetic blade punch 41, and the yoke 15 can be affected by an impact when dropped. And the rare earth magnet 12 can be peeled off.

  In this case, as shown in FIG. 7, the impact plate 16 that temporarily receives the rare earth magnet portion 11 at the dropping position of the rare earth magnet portion 11 punched out by the nonmagnetic blade punch 41 is, for example, It is installed at an angle of 45 degrees and is composed of a steel plate or the like, so that the rare earth magnet 12 of the falling rare earth magnet portion 11 is magnetically attached to the impact plate 16 and only the yoke 15 is not magnetically attached. It can bounce in the normal direction along the slope of the impact plate 16 and fall further downward.

  By providing such an impact plate 16, only the rare earth magnet 12 can be selectively and efficiently recovered from the cut rare earth magnet portion 11 (voice coil motor portion).

  By the way, in the above embodiment, the HDD 10 has been described as an example. However, the rare metal recovery processing method and apparatus described above are products such as a DVD drive, which have almost the same shape and structure according to the standard, regardless of the model or manufacturing year. It is the most effective for. Further, even when there is no standard, the present invention can also be applied to a mobile phone having a substantially similar structure. For example, even in the case of a mobile phone, if the magnetic sensors 31 and 32 are installed in the same manner as the rare metal recovery processing device 20, the internal vibrator and speaker are detected, and the cutting blade 41 (punch) matched to these sizes. It is possible to efficiently recover the rare metal portion.

  When a printed circuit board is targeted, information on the color, shape, and size of each element (for example, a tantalum capacitor is yellow or black, a plurality of pieces of information such as a rectangle, 2 mm to 7 mm, etc.) If it is input to (not shown), only the element corresponding to this is detected by the image sensor (identification sensor), for example, a plurality of small punches (cutting blades) attached to the movable arm are provided in the cutting machine 40, It is also possible to extract the element with this small punch.

  As described above, according to the rare metal recovery processing apparatus 20, the rare earth magnet portion (rare metal portion) 11 can be removed from the HDD 10 (object to be processed) in advance in the recycling process for recovering the rare metal, Even if sieving with a screen is performed in a subsequent process, clogging of the screen can be avoided. In addition, since only rare metal-containing parts such as rare earth magnets 12 can be efficiently recovered and collected, the distribution of the rare metal-containing parts can be achieved along with the highly efficient recovery as it is or through a further sorting step. Can be increased.

  Moreover, the HDD 10 (object to be processed) from which valuable rare metal-containing portions have been cut out in advance by a mechanical technique may be crushed and recovered to collect other metals, and the recovery of other metals is also efficient. Can be done well.

  In the above-described embodiment, the hard disk drive is described as an example of the object to be processed. However, as described above, the rare metal portion is similarly applied to a DVD drive, a mobile phone, a digital camera, or the like with little difference in shape and structure between products. Can be efficiently recovered, and the object to be processed is not limited to the above configuration.

  In addition, even in a workpiece that can be identified with an image sensor or the like such as a mounted printed board that is not stored in the housing, the rare metal portion is similarly recovered by changing the identification sensor 30. And can be applied to various objects to be processed.

  Furthermore, the above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention, and the present invention is not limited to the above-described embodiment.

  The recovery processing method according to the present invention can be used for a recovery processing apparatus that efficiently recovers valuable rare metals used in small home appliances and the like.
