Description

TECHNICAL FIELD The present invention relates to a linear object removing device, a linear object removing method, and a method for processing electronic and electrical device component scraps, and in particular, a linear object removing device suitable for application to recycling processing of used electronic and electrical devices. , to a method for removing linear objects and a method for processing scrap electronic and electrical equipment parts.

Devices for selectively removing specific foreign matter, such as linear objects, from objects to be sorted are known. Japanese Patent Application Laid-Open No. 2015-150505 (Patent Document 1) describes an example of a sorting device that sorts out a desired sorting object from a long mixed material by sorting with a vibrating screen and sorting with airflow.

In addition, from the viewpoint of resource conservation in recent years, it has become more and more popular to recover valuable metals from electronic and electrical equipment parts scraps such as waste home appliances, PCs, mobile phones, etc., and efficient recovery methods are being studied. It is In Japanese Patent Application Laid-Open No. 2015-123418 (Patent Document 2), after incinerating electrical/electronic component scrap containing copper, the scrap is pulverized to a predetermined size or less, and the pulverized electrical/electronic component scrap is processed in a copper smelting furnace. is stated.

However, the method described in Patent Document 1 only discloses a sorting device for sorting out long linear objects and long scattering objects, and the method is such that long strips such as plate-shaped, column-shaped, and cylindrical objects are disclosed. Sorting of objects to be sorted that includes foreign matter having a shape other than the shape of the object has not been performed.

As described in Patent Document 2, when incinerating electronic and electrical device component scraps in a smelting furnace, smelting inhibitors such as aluminum, antimony, iron, and nickel are present in electronic and electrical device component scraps. As a result, the processing efficiency of the smelting furnace that processes this may be reduced. In order to suppress the introduction of smelting inhibitors into the smelting furnace, it is desirable to perform a treatment in advance to reduce the smelting inhibitors as much as possible in the scrap electronic and electrical equipment parts that are introduced into the smelting furnace. .

In recent years, it has also been considered to separate and process single parts from electronic and electrical equipment parts scraps, but it is difficult to selectively separate and collect desired single parts from various and multi-shaped scrap parts. At present, it is still difficult and various problems remain. In particular, electronic and electrical equipment component scraps include linear objects such as coated wires and copper wires (hereinafter referred to as "linear objects" or "wire scraps"). Linear objects tend to get entangled with other parts and equipment when a desired single part is selected from a wide variety and many shapes of scrap parts, which may cause deterioration of separation accuracy and equipment trouble. Furthermore, since the covered wire contains Sb, which is a smelting inhibitor, in the covered portion, the contamination of the smelting furnace with the covered wire may affect the operation of the smelting furnace.

As a result of intensive studies, the inventors of the present invention have found that a sorting apparatus capable of efficiently sorting linear objects from objects to be sorted including various foreign substances having shapes other than plate-shaped objects and long objects, such as , have proposed a lineament removal device as described in WO 2019/151350.

JP 2015-150505 A JP 2015-123418 A WO2019/151350

However, when the sorting process of linear objects and plate-shaped objects was continuously performed using a sorting device as described in Patent Document 3, the fixed position of the filter of the sieving machine was damaged by long-term use. It was found that stress concentrates and damage such as cracks occurs.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments shown below are examples of devices and methods for embodying the technical idea of the present invention. not something to do.

(Linear object removal device)
As shown in FIG. 1, the apparatus for removing filamentous objects (filter section 30) according to the embodiment of the present invention includes a plurality of rods 2 extending in the supply direction of the raw material, and one end 2a of the plurality of rods 2. A plurality of filters 3 having beams 21 supporting a plurality of rods 2 and arranged adjacent to each other so as to partially overlap each other along the raw material supply direction, and a metal reinforcement provided to each of the filters 3. A jig 7 is provided.

The raw material is not particularly limited as long as it contains at least a linear material and a plate-like material. Although the linear object is not limited to the following, any linear member having a short diameter and a long diameter may be used. For example, various types of wiring such as electric wires, cables, conducting wires, etc. can be cited as linear objects. The plate-like object is not particularly limited as long as it is a plate-like member having a predetermined surface area and thickness. For example, a substrate, a plastic plate, a metal plate, etc. can be cited as plate-like objects.

A plate-shaped object typically has a surface area of 1 cm ² or more, and a member having a thickness of 2 mm or more can be suitably used. The linear object is not limited to the following, but for example, has a short diameter of 5 mm or less, more typically 1 mm or less and 0.1 mm or more, and a long diameter of about 1 to 10 cm, further about 1 to 5 cm. can be suitably used. The raw material may contain three-dimensional objects such as cylindrical, columnar, rectangular, and irregular lumps other than linear and plate-shaped objects.

A plurality of filters 3 are arranged in a vibrating screen machine (not shown). As the vibrating sieve machine, a generally available commercially available device may be used as long as it is a device capable of accommodating a plurality of filters 3 inside, or a dedicated device for accommodating the filters 3 may be used. may be used. As shown in FIG. 2, the plurality of rods 2 extend in the raw material supply direction with a certain gap y along the raw material supply direction. The size of the gap y is adjusted so that it can be sieved out from.

The beam portion 21 has a longitudinal direction in a direction intersecting the raw material supply direction, and typically has a hollow box shape. As shown in FIG. 1, the beam portion 21 is fixed in such a manner that one end 2a of each of the plurality of rods 2 is partially inserted into the beam portion 21, so that the plurality of rods 2 are supported by one end 2a of the plurality of rods 2. configured to support One end 2a of the plurality of rods 2 is a fixed end fixed to the beam portion 21, and the other end 2b of the plurality of rods 2 is a free end that is not connected to other members.

It is preferable that the plurality of filters 3 be inclined so that the height on the downstream side in the raw material supply direction is higher than the height on the upstream side in the raw material supply direction. If the plurality of filters 3 are arranged horizontally, the total length of the filters 3 becomes long, and the size of the device may become large. On the other hand, by arranging the plurality of filters 3 in an inclined manner, it is possible to secure a transport distance necessary for improving the sorting efficiency of the linear objects, thereby increasing the sorting efficiency between the linear objects and the plate-shaped objects. can be higher.

If the inclination angle of the filter 3 is too large, the raw material may hit the upper motor (not shown) above the vibrating screen machine housing the filter 3, or the raw material may protrude from the filter 3 and cause the raw material to fall. be. Therefore, the plurality of filters 3 are preferably arranged so that the inclination angle θ of the plurality of filters 3 with respect to the horizontal plane α is greater than 0° and less than or equal to 45°, more preferably more than 0° and less than or equal to 30°. has an inclination angle θ greater than 0° and not more than 15°.

The inclination angle θ of the plurality of filters 3 with respect to the horizontal plane α, as shown in FIG. The inclination angle θ of the filters 3 does not have to be the same angle, and can be changed to an appropriate angle according to the arrangement positions of the filters 3 . For example, it is possible to gradually decrease or increase the angle of inclination in the feed direction of the raw material.

The beam 21 extends substantially perpendicular to the plurality of rods 2, as shown in FIG. As shown in FIG. 1, the beam portion 21 includes a top surface 21a, a bottom surface 21b facing the top surface 21a, a rear side surface 21c connected to the top surface 21a and the bottom surface 21b and located upstream in the raw material supply direction, and the top surface 21a. A front side surface 21d connected to the bottom surface 21b and located downstream in the raw material supply direction is provided. A plurality of holes (not shown) for inserting the plurality of rods 2 are formed in the front side surface 21d, and one ends 2a of the plurality of rods 2 are respectively inserted and fixed in the plurality of holes.

By inserting and fixing a part of the plurality of rods 2 into the beam portion 21 in this way, the fixing between the plurality of rods 2 and the beam portion 21 is strengthened. As a result, even when the filter 3 has a beam portion 21 at one end 2a of the plurality of rods 2 and has a cantilever beam shape with the other end 2b being a free end, the filter 3 has a relatively specific gravity such as scraps of electronic and electrical equipment parts. It is possible to stably sort out materials with large . In addition, as shown in FIG. 5, if a connecting portion 200 for fixing the rods 2 is provided at one end side and the other end side of the rod 2, a linear object may be caught on the connecting portion 200, but the beam portion 21 is provided at one end 2a of the plurality of rods 2, and by adopting a cantilever shape in which the other end 2b is a free end, catching of linear objects is suppressed. In addition, as shown in FIG. 3 , an insertion hole 28 for inserting a fastening member for fixing the filter 3 to the vibrating sieve may be provided at the end in the longitudinal direction of the beam portion 21 .

The rods 2 and beams 21 that constitute the filter 3 are preferably made of a material with relatively high mechanical strength in order to prevent breakage due to supply of raw materials. On the other hand, even if the material of the filter 3 has high mechanical strength, if the weight is too large, damage such as cracks may occur in the stress-concentrated portion of the filter 3 after long-term use. In this embodiment, a resin material is used for the rod 2 and the beam portion 21 that constitute the filter 3 . As a result, the weight of the filter 3 can be reduced, and damage due to long-term use of the filter 3 can be suppressed.

A specific example of the resin material can be appropriately selected according to the weight of the raw material to be treated. Among them, considering mechanical properties such as bending strength, total weight, abrasion resistance, impact strength, and availability, the filter 3 is made of at least one of polyurethane, polyvinyl chloride, ABS resin, and polyacetal resin. It is preferably formed of, particularly preferably of polyacetal resin.

In examining materials that can be made lighter, we evaluated the bending stress safety factor and the amount of deflection. The bending stress safety factor was calculated in the case where the inertial force applied during vibration was applied to the beam portion 21 as a static load, and was compared and evaluated with the existing stainless steel (SUS304) sieving net. By changing the material of the sieving mesh from stainless steel to, for example, polyacetal resin, which is a kind of resin, the weight of the filter 3 can be reduced to about one fourth, and the bending stress safety factor is about improved by a factor of two.

On the other hand, the amount of deflection is 0.31 cm in the case of the current stainless steel filter 3, whereas if polyacetal resin is used as the material of the filter 3 for weight reduction, the amount of deflection is 4 cm. .04 cm. Therefore, if only polyacetal resin is used as the material of the filter 3 , the raw material may flow unevenly to both sides of the filter 3 .

In this embodiment, by providing the filter portion 30 in which the reinforcing jig 7 made of metal is combined with the filter 3 made of resin, the bending amount of the rod 2 of the filter 3 can be made as small as the reinforcing jig 7 . From the viewpoint of mechanical properties such as bending strength and total weight, it is particularly preferable that the reinforcing jig 7 is made of stainless steel, iron, or the like among metals. For example, since the amount of bending of the stainless steel reinforcing jig 7 is about 0.06 cm, the stainless steel reinforcing jig 7 and the resin filter 3 are combined to make the filter 3 entirely made of resin. Compared to the case, the deflection amount of the entire filter 3 can be reduced. In this way, by reinforcing the resin filter 3 with the metal reinforcing jig 7, the stress applied to the filter 3 can be received by the reinforcing jig 7, so that the filter can be durable for a long period of time. Therefore, it is possible to provide a linear object removing device having properties.

As shown in FIG. 1, the reinforcing jig 7 includes a first reinforcing portion 71 covering the bottom surface 21b and the rear side surface 21c of the beam portion 21, and a second reinforcing portion 72 projecting downward from the bottom surface of the first reinforcing portion 71. , an angle adjustment plate 73 disposed between the first reinforcing portion 71 and the second reinforcing portion 72 . The angle adjusting plate 73 may be arranged only under the first reinforcing portion 71 around the fixed portion of the filter 3 in order to reduce the total weight.

The first reinforcing portion 71 may have any shape as long as it can cover at least the bottom surface 21 b and the rear side surface 21 c of the beam portion 21 . Typically, an L-shaped angle having a bottom reinforcing portion 71a that reinforces the bottom surface 21b of the beam portion 21 and a rear side reinforcing portion 71b that reinforces the rear side surface 21c of the beam portion 21 can be used. If the plate thickness of the first reinforcing portion 71 is too thin, the strength will decrease, and if it is too thick, the total weight will increase. is preferred. The beam portion 21 and the first reinforcement portion 71 can be fixed by fastening members 76a and 76b such as screw parts, but the fixing method is not limited to the illustrated example.

As shown in FIG. 3, the second reinforcing portion 72 extends along the direction intersecting with the rod 2, that is, along the longitudinal direction of the beam portion 21 so as to support the beam portion 21 below the beam portion 21. there is As shown in FIG. 1, between the bottom surface of the first reinforcing portion 71 and the second reinforcing portion 72, a tapered angle adjusting plate 73 whose thickness gradually increases along the raw material supply direction is arranged. be. The angle adjustment plate 73 is arranged on the bottom surface of the first reinforcing portion 71 so that the height on the downstream side in the raw material supply direction is higher than the height on the upstream side in the raw material supply direction, and the inclination angle θ of the filter 3 is adjusted appropriately. The thickness is adjusted so as to form an angle. If the plate thickness of the second reinforcing portion 72 is too thin, the strength decreases, and if it is too thick, the total weight increases. 3) can be 30 mm or more, more typically 40 to 50 mm.

Preferably, the reinforcing jig 7 further includes a rib 74 that reinforces at least one of the front side surface 72 a and the rear side surface 72 b of the second reinforcing portion 72 . As shown in FIG. 3, it is preferable that a plurality of ribs 74 be arranged at regular intervals along the extending direction of the second reinforcing portion 72 . By providing the ribs 74, the reinforcing effect of the reinforcing jig 7 can be further obtained.

As shown in FIG. 1 , the rib 74 is provided on the front side surface 72 a side of the second reinforcing portion 72 and serves as a front rib for reinforcing the space between the front side surface 72 a of the second reinforcing portion 72 and the bottom surface of the angle adjusting plate 73 . A rib 74 a and a rear rib 74 b provided on the rear side surface 72 b side of the second reinforcing portion 72 to reinforce the space between the rear side surface 72 b of the second reinforcing portion 72 and the bottom surface of the angle adjusting plate 73 . Here, the connection position of the second reinforcing portion 72 to the bottom surface of the angle adjusting plate 73 is adjusted so that the width w1 of the rear rib 74b along the horizontal direction is larger than the width w2 of the front rib 74a. is preferred. As a result, the second reinforcing portion 72 can be further reinforced, and a more appropriate reinforcing effect can be obtained while preventing damage to the filter 3 tilted at the tilt angle θ.

Preferably, the reinforcing jig 7 further includes a stress dispersing portion 75 provided at least at the connecting portion between the rib 74 and the second reinforcing portion 72 . The stress dispersing portion 75 is provided at least at a connecting portion between the rib 74 (the front rib 74a and the rear rib 74b) and the front side surface 72a or the rear side surface 72b of the second reinforcing portion 72, and each has a convex curved surface. processing is done. Since the stress applied to the rib 74 and the second reinforcing portion 72 can be dispersed by providing the stress dispersing portion 75, the reinforcing jig 7 having durability suitable for long-term use can be obtained. The stress dispersing portion 75 can also be provided at the connection portion between the rib 74 (the front rib 74 a and the rear rib 74 b ), the second reinforcing portion 72 and the angle adjustment plate 73 .

As shown in FIG. 3 , the second reinforcing portion 72 has notches at both ends in the longitudinal direction of the beam portion 21 for dispersing the stress applied to the second reinforcing portion 72 . More preferably, a portion 77 is formed. The second stress dispersion portion 77 is formed to have a curved R shape that is smooth from the bottom to the top. The second stress dispersion portion 77 can suppress breakage of the second reinforcement portion 72 due to long-term use.

As shown in FIG. 1, when the filters 3 are arranged adjacent to each other in the raw material supply direction, the upper surface 21a of the beam portion 21 included in one filter 3 is located upstream of the first filter 3 in the raw material supply direction. It is preferable to arrange so that it is arranged immediately below the free ends at the other ends 2b of the plurality of rods 2 provided in the other filters 3 arranged adjacently.

In the arrangement of the filters 3 as shown in FIG. 1, when the raw material is conveyed from one filter 3 to another filter 3, plate-like objects such as substrate scraps stand at the boundary between the filters 3 and 3. However, the top surface 21a of another filter 3 should be placed directly under the free end side of the other end 2b of the plurality of rods 2 of one filter 3 so that the upper surface 21a of the other filter 3 overlaps. Therefore, it is possible to suppress a phenomenon in which a plate-shaped object accidentally falls to the lower side of the sieve at the boundary between the filters 3 and 3 .

In addition, when the raw material is conveyed from one filter 3 to another filter 3, the raw material does not drop directly onto the plurality of rods 2, but can be once dropped onto the upper surface 21a. 2, the sorting apparatus can be operated for a longer period of time without requiring replacement of parts.

Furthermore, as shown in FIG. 1, a falling rod extending in a direction intersecting the extending direction of the plurality of rods 2 on one end 2a of the rod 2 and extending upward from the one end 2a of the rod 2 in a substantially vertical direction. A preventer 22 may be provided. The fall prevention tool 22 can be arranged in the space between the other end 2b of the rod 2 and the one end 2a of another rod 2 arranged below the other end 2b of this rod 2 . The drop prevention tool 22 prevents the raw material falling from the other end 2b of the rod 2 onto the upper surface 21a of the beam 21 from accidentally dropping to the underside of the sieve. In particular, when the distance between the one end 2a and the other end 2b of the rod 2 is long, by providing the fall prevention tool 22, the raw materials which should not be separated to the sieve side are prevented from falling to the sieve side. can be done. In addition, although the example of FIG. 1 shows an example extending in a substantially vertical direction from the upper surface 21a of the beam portion 21, it is of course possible to slightly incline toward the upstream side or downstream side in the supply direction.

As shown in FIG. 4, the surfaces of the plurality of rods 2 are preferably formed with a curved surface R for sieving the wire scraps to the bottom side of the sieve. Since the wire waste has a linear shape, if the surface of the rod 2 is angular, the wire waste is caught on the rod 2 and floats up when it moves along the raw material supply direction, and it may not be successfully sieved to the lower side of the sieve. There is

By providing the surfaces of the plurality of rods 2 with the curved surfaces R, the contact between the wire scraps and the rods 2 can be made smoother, so that the efficiency of screening the wire scraps can be further enhanced. The surfaces of the plurality of rods 2 may be subjected to surface treatment or the like for smooth contact with wire scraps.

Here, it is preferable that the distance between the rods 2 and the diameter of the rods 2 are adjusted based on the size of the plate-like object X such as a substrate contained in the scrap electronic and electrical equipment. Specifically, for example, as shown in FIG. 4, the average size (diameter) of the plate-shaped objects X contained in the electronic and electrical equipment parts scraps supplied onto the filter is X mm, the distance between the rods is y, the rod It is preferable that the distance y and the radius r between the rods 2 are adjusted so as to have the relationship r ² +(y+2r) ² =(x+r) ² , where r is the radius.

For example, it is preferable that the distance between the plurality of rods 2 is adjusted to be 1.2 to 6 times the representative diameter of the linear object and narrower than the minimum short diameter of the plate-shaped object. Here, the "representative diameter" of the linear object is obtained by extracting arbitrary 10 points of the linear object from the raw material and calculating the average diameter of the 10 extracted linear objects on the major axis side. This was repeated 5 times, and the average value of the 5 times was taken as the "representative diameter". Similarly, for the minimum minor axis of the plate-shaped object, 10 arbitrary points of the plate-shaped object in the raw material are extracted, and the average diameter of the extracted 10 points of the plate-shaped object on the minor axis side is calculated. means the average value of repeated times.

Specifically, but not limited to, for example, the rod diameter (2r) can be 1 to 15 mm. The rod spacing can be 1-10 mm, more preferably 1.5-5 mm. The length of the rod 2 in the material supply direction is 100-600 mm, more preferably 200-400 mm. When it is shorter than 100 mm, when there are many long filaments, they are less likely to fall under the sieve, and the filaments tend to clump on the sieve. On the other hand, if it exceeds 600 mm, the vibration of the rod 2 may tend to increase.

As shown in FIG. 6, a table 4 can be arranged further upstream of the filter 3 . Electronic and electrical equipment parts scraps are placed on the filter 3 from the table 4, and vibration is applied on the filter 3 from a vibration adding means (not shown), so that noble metal-containing substances such as substrates, ICs, and other plate-like objects are placed on the sieve side. can be sorted out, and linear objects including coated wires etc. can be sorted out on the lower side of the sieve.

The table 4 is composed of a flat plate having substantially no gaps for sieving out the linear material, and the raw material is first supplied onto the table 4 before being supplied to the filter 3 . By first vibrating the raw material supplied onto the table 4, the raw material can be dispersed on the table 4. FIG. By supplying the dispersed raw material from the table 4 onto the filter 3, the efficiency of sorting the linear objects and the plate-shaped objects in the filter 3 can be further enhanced. Further, by once vibrating the material on the table 4, there is an effect that the direction of the linear material can be aligned. The vibration applied to the table 4 may be of the same degree as the vibration applied to the filter 3 .

In this embodiment, it is more preferable to sift the raw material by placing a holding member 5 for holding the raw material as shown in FIG. 7(a) on the raw material placed on the filter 3. The pressing member 5 should have a material and a shape that can suppress rotation of the plate-shaped object contained in the raw material due to the vibration applied to the filter 3 and can suppress falling out from between the rods 2. good.

For example, as the pressing member 5, an elastic member such as a rubber material, a resin material, or a sponge material having elasticity and capable of holding the raw material by its elastic force can be used. A vinyl sheet or the like having elasticity can also be used as the pressing member 5 . By using an elastic member as the pressing member 5, it is possible to keep a certain distance from the vibrating filter 3 and move with the raw material. The pressing member 5 may be a member having one or a plurality of holes so as to have an appropriate frictional force with the raw material.

It is possible to stack a plurality of pressing members 5 on the raw material supplied on the filter 3. However, excessive stacking of the pressing member 5 may result in large variations in the shape and size of the parts contained in the raw material. , it may be difficult to adjust the load. It is possible to apply a load so as to press the pressing member 5 from above the raw material, but if the load is too large, a plate-like object such as a substrate may clog between the pressing member 5 and the filter 3. .

The thickness of the pressing member 5 can be appropriately selected depending on the raw material to be used. Although not limited to the following, when a rubber material is used as the pressing member 5, it is preferable to arrange a sheet-like member having a thickness of about 2 to 20 mm so as to cover the raw material. By covering the raw material with the pressing member 5, an appropriate load is applied to the parts of electronic and electric equipment, and the sieving efficiency is improved. A weight such as an iron plate may be placed on the pressing member 5 to adjust the load.

As shown in FIG. 7(b), the pressing member 5 has one end on the raw material supply side that is fixed to the vibrating sieve machine, and the other end on the raw material discharge side that is connected to the vibrating sieve machine. It preferably has a free end that is not fixed to the. By fixing one end of the pressing member 5, it is possible to suppress the flow of the pressing member 5 to the raw material discharge side together with the raw material. Since it becomes easier to move according to the shape and vibration of the raw material, it becomes easier to hold down the raw material more appropriately.

As shown in FIG. 7B, the pressing member 5 has its fixed end fixed above (upper end) on the feed side of the vibrating sieve machine that feeds the raw material onto the filter 3 . Starting from this fixed end, the holding member 5 is hung from the material supply side toward the material discharge side. It is possible to move up and down while holding down . With such a structure, the raw material is easily vibrated on the raw material supply side, making it easy to align the direction of the linear material. By pressing with , the linear substances can be easily sifted down to the lower part of the filter 3 . A plurality of pressing members 5 may be arranged from the material supply direction to the material discharge direction. The pressing member 5 may be arranged on each of the plurality of filters 3, or may be arranged only on the most upstream filter 3 when viewed from the raw material supply side.

As described above, according to the apparatus for removing linear objects according to the embodiment of the present invention, by including the metal reinforcing jig 7 for reinforcing the filter 3 and further including the resin filter 3, In comparison, the weight of the entire filter section 30 can be reduced, and the durability can be improved. As a result, it is possible to obtain a linear object removing apparatus that is durable enough to withstand long-term use.

(Method for removing linear objects)
The method for removing linear objects according to the embodiment of the present invention can be carried out using the above-described linear object removing apparatus as shown in FIG. That is, in the method for removing linear objects according to the embodiment of the present invention, the resin extends with a certain gap y along the supply direction of the raw material and sieves out the linear objects contained in the raw material from the gap y. a plurality of rods 2 made of resin, a beam portion 21 made of resin that supports the plurality of rods 2 at one end of the plurality of rods 2, a first reinforcement portion 71 that covers the bottom surface 21b and the rear side surface 21c of the beam portion 21, and the first reinforcement A plurality of filter portions 30 each provided with a metal reinforcing jig 7 provided with a second reinforcing portion 72 protruding from the bottom surface of the portion 71 and extending along the longitudinal direction of the beam portion 21 are arranged along the supply direction. They are arranged adjacent to each other so as to partially overlap each other, vibrate the filter unit 30, and sieve the linear substances supplied onto the filter unit 30 from the gap y.

The sieving of the raw material is preferably repeated two or more times. For example, when an electronic/electrical device component is used as a raw material, a substrate with a component and a substrate without a component in the electronic/electrical device component are separated by sieving in the first stage. By further sieving component-free substrates in the second stage of sieving, approximately 40% of all electronic and electrical device components can be transferred to the sieving side.

Further, in addition to the two-step sieving, by further adjusting the load on the electronic and electrical device parts by the pressing member 5, about 7 of the substrates included in the electronic and electrical device parts are removed when the second stage of sieving is completed. It is possible to transfer about 90% of the wire waste (covered wire) to the lower side of the sieve.

The magnitude of the vibration to be applied to the filter section 30 is arbitrary, and is not particularly limited as long as it is large enough to align the directions of the linear objects. The direction of vibration is preferably the same as the direction in which the rod 2 extends, that is, the direction parallel to the supply direction of the raw material (front-rear direction). In the case of continuous treatment, it is preferable to vibrate not only in the front-rear direction but also in the vertical direction. Any amplitude may be used as long as the material moves forward, and it can be appropriately set according to the throughput of the material. A device for supplying vibration to the filter unit 30 may be either a linear type or a rotary type, and is not particularly limited as long as it generates a predetermined vibration.

For example, vibration can be applied to the upper surface of the rod 2 of the filter part 30 so that the vibration width in the vertical direction (vibration width in the vertical direction) and the vibration width in the front-rear direction are 0.5 to 10 mm. If the vibration width is too large, the wire scrap separation efficiency may decrease, and if the vibration width is too small, a significant effect of vibration cannot be obtained. More preferred. Alternatively, although not limited to the following example, vibration with a frequency of about 50 Hz is applied to the filter section 30, and the vibration transmission rate (vibration rate) transmitted from the vibration source to the filter section 30 is 10 to 90%. The amplitude of the vibration can be adjusted to be between

Vibration can be applied to the filter section 30 intermittently or continuously. By applying vibration continuously, wire scraps can be collected stably, and by applying vibration intermittently, the power required for driving the vibration can be omitted.

(Method for processing electronic and electrical device parts scrap)
Electronic and electrical equipment component scraps can be processed using the linear object removing apparatus of FIG. Here, the "electronic and electrical equipment parts scrap" in the embodiment of the present invention is scraps obtained by crushing electronic and electrical equipment such as waste home appliances, PCs, mobile phones, etc. After being collected, it is reduced to an appropriate size. Refers to crushed. In the present invention, the crushing to obtain electronic and electrical equipment parts scraps may be carried out by the processor himself or may be purchased after being crushed in the market. The crushing means is not limited to a specific device, but does not include devices belonging to the category of crushers, and crushing that does not damage the shape of the parts as much as possible is desirable.

Although not limited to the following, in the present embodiment, the electronic and electrical equipment parts scrap is preferably crushed to a maximum diameter of 100 mm or less, more preferably 70 mm or less, furthermore 50 mm or less. Electronic and electrical equipment parts scraps are crushed to a minimum diameter of 5 mm or more, more preferably 10 mm or more, and even more preferably 15 mm or more, because even if they are made too small by crushing, etc., they cannot be said to be efficient in terms of separation efficiency. is preferred. In addition, it is preferable to roughly crush the raw materials of the electronic and electrical device component scraps according to the present embodiment in advance, and then separate them into individual pieces such as capacitors, plastics, substrates, wire scraps, ICs, connectors, metals, and the like. . This makes it easier to sort out specific single parts.

Roughly crushed scraps of electronic and electrical equipment parts may be sorted by wind force, and lightweight objects sorted by wind sorting at 3 to 20 m/s may be processed in this embodiment. Combining wind sorting improves the sorting efficiency. Air sorting may be performed before or after screening the wire waste as described below. Although it depends on the materials contained in electronic and electrical equipment parts scraps, the separation of precious metal-containing materials such as substrates and ICs from metals is preferably 10 to 18 m/s, more preferably 15 to 18 m/s. The optimum wind speed is preferably 5 to 15 m/s, more preferably 8 to 12 m/s, in order to improve the fraction of metal and metal.

In addition, when separating plastics from parts scraps containing films, powders, plastics, etc., which affect clogging of the filter 3 and erroneous detection of the sensor in the subsequent sorter sorting, the wind speed is 5 to 8 m / s. is preferably 6 to 7 m/s.

In this embodiment, for example, wire scraps are sieved from raw materials, that is, wire scraps contained in electronic and electrical equipment component scraps, using the linear object removing apparatus shown in FIG. . The term "wire scraps" refers to wires used in wiring between devices of electronic and electrical devices and inside devices made of copper, copper alloys, aluminum, or the like. Wire scraps include covered wires, copper wires, long and thin wire-like block wire scraps, and the like. Specifically, a stranded wire, a copper wire unraveled from a braid, or the like can be suitably included as a linear object. These copper wires and the like have a small minor axis, for example, a minor axis of 0.5 mm or less, further 0.2 mm or less, and thinner materials with a minor axis of about 0.05 mm. Some of these copper wires and the like have a long diameter of less than 50 mm due to crushing, but there are also cases where they exceed 50 mm.

Wire scraps tend to get entangled with other parts and equipment when electronic and electrical equipment parts scraps are sorted, and there is a risk of deterioration of separation accuracy and equipment troubles. In particular, since wire waste including long and thin copper wires, especially copper wires, is soft, it tends to be easily entangled with other parts or other linear objects, especially in the physical sorting process. Among the wire scraps, the coated wire contains approximately 0.3% of Sb, which is a smelting inhibitor, in the coated portion. There is also the problem that the contamination of the smelting furnace with the coated wire affects the operation of the smelting furnace.

In the present embodiment, when wire scraps are sieved from electronic and electrical equipment component scraps using the wire-like substance removing apparatus of FIG. can be removed out of the smelting furnace process.

Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in each embodiment. For example, some components may be deleted from all components shown in the embodiments. Furthermore, components of different embodiments may be combined as appropriate.
