DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a disassembly apparatus and a processing method of an electronic apparatus according to an embodiment of the present invention will be described with reference to the drawings. Note that, for convenience, an electronic device is illustrated by an example of a television receiver.

(Embodiment) FIG. 1 is a conceptual configuration diagram of an electronic apparatus disassembling apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of a main part of FIG. 1, and FIG. 3 is a flowchart of FIG.

In FIGS. 1 to 3, the television receiver is mounted on a transport pallet, and is transported from a lower right corner to an upper left corner in the figure by a transport conveyor, for example, a chain conveyor stretched in parallel. In the transportation process, semi-automated processes from the removal of the back cover to the peeling and removal of the adhesive tape are performed. Hereinafter, the steps of each process shown in FIG. 3 will be described.

[Step 1 / loading device] A waste television receiver is mounted on a transport pallet by a loading device and carried out. In the embodiment of the present invention, it was manually mounted on the transport pallet. Of course, the waste television receiver transported by the transport conveyor or the like may be automatically detected and automatically loaded on the transport pallet by the input device. Similarly, the robot for lifting the waste television receiver may have an arbitrary configuration, such as vacuum suction of a CRT tube surface, or holding both sides of a cabinet (housing) between two arms.

[Steps 2-4 / tilt device-cleaning device-tilt device] A transport pallet with a television receiver loaded on the side where the transport pallet has not yet been loaded, of the two tiltable worktables. I do. An operator removes a back cover on the rear side of a housing (cabinet) constituting the television receiver.

In the next step, dust accumulated in the waste television receiver is automatically removed by air blow. Next, the television receiver together with the transport pallet is placed on the tiltable worktable again, and the deflection coil (DY), the chassis, and the like are manually removed. Back cover and D
The removed members such as Y are mounted on the conveyor behind,
Automatically unload as prescribed. Hereinafter, an embodiment of the tilting device and the cleaning device will be described with reference to FIGS.

FIG. 4 is a side view of the concept of the tiltable worktable and the cleaning device, FIG. 5 is a plan view of the main part of FIG. 4, FIG. 6 is a side view of the main part of the tiltable worktable, and FIG. FIG. 8 is a side view of a main part of the cleaning device.

In FIG. 5, the television receiver 100
Are transported from left to right in the figure by the conveyor 1.

The television receiver 100 which has been transported to the front of the first work table 40 (the left side in FIG. 5) is automatically transferred from the transport conveyor 1, for example, to the chain conveyor stretched in parallel. By a belt conveyor device or the like (not shown) driven in a direction orthogonal to the first work table 40, the work table is transferred together with the transport pallet 2 onto the first worktable 40 which can be tilted.

An operator is located in front of the worktable 40 which can be tilted, and after confirming that the television receiver 100 has been transferred, the worker is activated by pressing a foot switch (not shown) or the like. A signal is sent to tilt the worktable 40 to a predetermined angle, for example, in a range of about 45 degrees to 75 degrees.

The television receiver 100 mounted almost at the center of the work table due to the inclination of the work table 40 slides on the transport pallet and hits the stopper 2, and is located within the reach of the operator.

Here, the operator removes the back cover. After the work is completed, the work table returns to the horizontal state, and the transport pallet 2 on which the television receiver is mounted is returned to the transport conveyor 1 again by the automatic transfer device. The returned television receiver is carried into the cleaning device 45 in the next step by the transport conveyor.

In the case of a small television receiver of about 14 inches to 20 inches, the work can be performed in a horizontal state without tilting the work table 40. In addition, even in the case of a large-sized one, the operator can arbitrarily set the inclination angle according to the model and the outer shape.

In FIG. 5, two worktables 40 are arranged before and after the cleaning device 45, respectively. The first reason is to allow a wide range of dismantling processing capabilities of the television receiver. That is, the number of personnel can be increased according to the processing amount.

The second reason is that when the next television receiver to be dismantled is transported while the disassembly work is being performed on one of the two adjacent work stations, the other work table is disengaged. Acceptable above. That is, the time required for disassembly varies depending on the size and type of the television receiver.
Therefore, it becomes a preliminary receiving place when it takes longer than a certain processing time. In this case, naturally, the worker moves to the next work table to perform the work.

Next, the structure of the tiltable worktable 40 will be described with reference to FIGS. 6 and 7, the work table 40 includes a frame 31 and transport belt conveyors 39, 39 arranged side by side incorporated in the frame 31.
And a drive cylinder 33 attached to the lower surface of the frame 31 and a base frame 34.

The conveyor belt conveyor is composed of two parallel belts, and conveys the conveyor pallet 2 to the vicinity of the stopper 32 and stops automatically.

One end of the frame 31 is hinged by a bearing 35 and a shaft 36 so as to be rotatable. The rod end member of the cylinder 37 is hinged to the other end side, and constitutes a link mechanism in which each fulcrum can rotate.
When fluid pressure such as air or hydraulic pressure is supplied to the cylinder 37 by this configuration, the piston rod of the cylinder moves,
The frame 31 is inclined at a predetermined angle.

It is needless to say that the means for inclining the frame 31 may have any structure other than the above. For example, an eccentric disk may be attached to the motor shaft to tilt the plate. Further, the plate may be inclined by a cam mechanism or the like (neither is shown).

Next, the cleaning step will be described. The periphery of the television receiver mounted on the transport pallet 2 and transported to a predetermined position by the transport conveyor 1 is shut off in a substantially airtight state by a closed box 46 lowered from above.

A spray nozzle 47 and an exhaust duct 48 are provided near the ceiling of the closed box 46.

Thereafter, high-pressure air is blown out from a plurality of spray nozzles 47 disposed near the ceiling toward the television receiver (air shower 49), and the neck, DY and funnel portions of the electron gun of the CRT, Inside of the cabinet,
Blows off dust adhering and accumulating on printed circuit boards and various wirings housed in cabinets. The exhaust duct 48 is also activated at the same time as the air ejection, so that the soaring dust is sucked and discharged. The air ejection time was about 5 seconds to several tens of seconds.

After the cleaning is completed, the closed box is raised, and the television receiver mounted on the transport pallet 2 is sent to the next step by the transport conveyor 1.

In the next step, the television receiver is again taken together with the transport pallet onto the tiltable second workbench (arranged on the right side of the cleaning device in FIG. 5).
The DY section (polarizing coil and neck printed circuit board) attached to the RT neck section and the chassis are removed.

In the process of removing the DY section,
Since the inside of the television receiver has been cleaned in advance, dust sowing is greatly reduced, and does not adversely affect the working environment and equipment.

After the removal of the DY section and the like, the CRT attached to the cabinet is again transported together with the transport pallet by the transport conveyor, to the next cabinet cutting step and CR.
It is sent to the T removal process.

As described above, according to steps 2 to 4 in FIG. 3, the removal of the back cover and the DY section and the removal of dust in the cabinet can be performed efficiently, and the disassembly work after the next step can be automated. Also, the tiltable worktable can efficiently preprocess television receivers of various inch sizes and shapes.

[Step 5 / Bottom Plate Cutting Device] The bottom plate of the wooden cabinet is cut into a U-shape to facilitate removal of the CRT. Hereinafter, an embodiment of a casing bottom plate cutting (casing disassembly) apparatus will be described with reference to FIGS.

FIG. 9 is a flowchart (flowchart) of a television receiver disassembling process according to an embodiment of the present invention, FIG. 10 is a plan view of a main part of a housing disassembling apparatus according to an embodiment of the present invention, and FIG. 10 is a perspective view of a process of forming a U-shaped cut groove on the main surface (bottom / bottom plate) of the housing to disassemble the housing of the video equipment, and FIG. FIG. 3 shows a perspective view of a state in which the bottom surface (bottom plate) has been opened after finishing the processing.

The television receiver 100 shown in FIGS. 9 to 13 has a CRT 51 (cathode ray tube / CRT), a housing (cabinet) 50 screwed to the outer peripheral surface (end surface) of the CRT 51, and a housing 50. (Circuit (control circuit unit)) 52, a speaker device 55 disposed near the CRT 51, and printed wiring boards 53 and 57 mounted on side plates.

Further, as shown in FIG. 13, the CRT 51 has a metal band 58 (explosion-proof reinforcing band) wound around the outer peripheral surface (the end surface of the display screen) in a predetermined manner, and mounting brackets 59 are spot-welded at four places. It is arranged by means of.

Next, a description will be given of a housing disassembly procedure of the general television receiver (hereinafter, referred to as a television).

FIG. 9 is a sectional view of the television housing showing “cut groove processing → disassembly →
Flow chart of "Removal of components", FIG.
A state in which a waste television is mounted on the apparatus and transferred to a fixed position, that is, step 2 is shown.

Next, the transport pallet 2 is raised from above the transport conveyor 1 by the air cylinder 9 (step 3).
A).

Thereafter, the casing 50 of the discarded television is moved to the X-axis and Y-axis.
Position in the axial direction. (Position determination / step 4A).
Positioning of the housing 50 in the Y-axis direction is performed by two opposed air cylinders 4 and 4 and plates 5 and 5 attached to the tip of a cylinder rod. As a matter of course, one of the two air cylinders is advanced to the home position first, and then the other air cylinder is advanced.

The positioning in the X-axis direction is similarly performed by the X-axis direction positioning means 3 in a predetermined manner. In this case, the air cylinders 7, 7 which move up and down in the Z-axis direction, the air cylinders in the X-axis direction (not shown), and the plates 8, 8 attached to the tip of the cylinder rod 7 are used at a predetermined timing.

Next, the dimensions of the determined housing in the X-axis, Y-axis and Z-axis directions are measured (step 5A / main surface position measurement).

The main surface position is measured in preparation for the cutting groove processing in the next step 6A, and a non-contact sensor such as a laser beam sensor or an ultrasonic sensor is used.

X-axis, Y-axis, and Z-axis direction sensors 14,
15 and 16 are operated, and the main surface positions (bottom surface,
The top and both sides are measured and recognized. The cutting tool is driven in a predetermined manner based on the position recognition data.

In step 6A, each main surface of the casing 50 is cut by cutting means, for example, at least one of end milling, laser processing or water jet processing which rotates at high speed.

The means for driving the cutting tool in a predetermined manner may be implemented by arbitrarily using a general three-axis to five-axis control robot such as a scalar type robot.

The rotation speed of the end mill tool is several hundred RPM to 25,000 RPM when the tool diameter is 3 mm to 20 mm.
It was about PM. Preferably 8.0 for a tool diameter of 12 mm
It was about 00 RPM to 10,000 RPM.

FIG. 12 shows a process in which a U-shaped cutting groove 60 is formed on the bottom surface (bottom plate) of the housing 50 by using two rotation driving means 12 and a cutting tool (end mill) 13. In addition, even if it is only one set of a rotation drive means and a cutting tool, it does not interfere with one direction.

FIG. 13 shows a state in which the bottom surface of the housing is opened. Thereafter, steps 7A and 8A are sequentially performed to complete the cycle of processing the cut groove in the housing.

Thereafter, in another step (another stage),
The nut to which the fitting 59 has been fastened is removed by a robot (not shown) or manually. Then, remove the cathode ray tube, chassis, printed wiring board, speaker device, etc. manually or by robot means not shown,
After that (all are not shown), it may be transferred to the separation / regeneration processing step (step 9A).

It is preferable that the operation of folding open each main surface of the housing 50 and the operation of removing each component are performed in a step different from the step of processing the cut groove. However, the cutting step may be separately performed in the same step.

In the flow shown in FIG. 9, the steps may be interchanged, added, or deleted.

Further, it goes without saying that the shape and the position of the cut groove formed in the U-shape may be arbitrarily determined and the cut groove may be formed at an arbitrary position. For example, the ridges at the four corners in the Z-axis direction (intersections between the top surface and side surfaces or intersections between the bottom surface and side surfaces) and the X-axis and Y-axis directions are connected in place so that the main surface does not fall down during machining. Groove processing may be performed while leaving portions (not shown).

When a U-shaped cutting groove is to be formed not only on the bottom surface but also on the top surface and both side surfaces, the housing is rotated by 90 degrees by a housing rotating means (not shown) → position measurement of the main surface → cutting The above procedure may be repeated. FIG.
3 shows a disassembled state in which two main surfaces are opened. Further, only the ridges at the four corners in the Z-axis direction may be cut, and in a separate step, each main surface may be pushed down by forcible force to open.

According to the above embodiment, when the means for rotating the end mill tool at a high speed is used for the cutting groove processing, dry processing can be performed without using water or the like.

In the case of laser processing, three-dimensional processing can be performed more easily, and high-speed curved surface processing can be performed.

In the case of the water jet, the present invention can be applied not only to the cutting of the housing but also to the glass cutting of a cathode ray tube.

As described above, according to step 5 in FIG. 3, the disassembling operation of the discarded television receiver (cutting of the bottom plate of the housing) can be automated.

[Steps 6-7 / CRT removal device to CRT transfer device] An operator removes the fastening screw and removes the CRT from the cabinet. In addition, peripheral parts (ground wire,
Remove the degaussing coil). The cabinet, the detached parts, and the CRT are transported to the next CRT processing step on the transport pallet.

[Step 8 / Electron Gun Cutting] Outer diameter is about 20
A diamond grindstone having a thickness of about 0 mm and a thickness of about 2 mm or less is rotated at a rotational speed of about 3,000 to 5,000 RPM, and is moved straight or in a gentle arc in one direction to cut the electron gun neck of the cathode ray tube. . The cut electron gun is transported to the recycling process, and the CRT is transported to the next process.

[Step 9 / metal band removal device]
The metal band around the CRT for preventing implosion is heated by high frequency and removed. Hereinafter, an embodiment of the metal band removing device will be described with reference to FIGS.

FIG. 15 is a conceptual diagram showing a process of disassembling a metal band for preventing implosion of a cathode ray tube in one embodiment of the present invention.
The principal part block diagram which looked at the disassembly apparatus from the side direction is shown.

FIG. 16 is a perspective view of a main part of a metal band disassembly device for preventing implosion in one embodiment of the present invention, and FIG.
Circuit diagram of an equivalent circuit of the high-frequency heating means constituting FIG. 18,
Is a side view of a main part of an example of a cathode ray tube used for the description of the present invention,
FIG. 19 shows a flowchart (flowchart) of the disassembly step in one embodiment of the present invention.

A cathode ray tube 51 shown in FIG. 18 has a panel portion, a funnel portion, a neck portion, an implosion preventing metal band 58 wound around the panel portion, and an implosion preventing metal band. Mounting brackets (tabs) 59 are provided at four corners by spot welding. In addition,
Since the internal configuration of the cathode ray tube is not the subject of the present invention, the description is omitted.

In FIGS. 15 and 16, reference numeral 24 denotes a high-frequency heating device (specifically, a high-frequency induction heating device), and reference numeral 11 denotes a mounting bracket (tab) 59 which is constantly pressed at 4 kg to 6 kg when heating the metal band for preventing implosion. A tab pressing means 25, an induction heating coil 25 for heating the implosion-preventing metal band to 350 to 500 degrees Celsius, and a cathode ray tube (23) through an opening (through hole) provided in the center of the transport pallet 2 CRT lifting means for lifting CRT) to a predetermined position in the induction heating coil 25;
22 is a CR planted on the CRT mounting surface side of the transport pallet 2
The T support means is composed of four pin members. Reference numeral 1 denotes a transfer pallet transfer means for transferring the transfer pallet 2 by a predetermined constant pitch, for example, a transfer conveyor.

Next, a procedure for disassembling a metal band for preventing implosion of a general cathode ray tube will be described. FIG. 19 shows a flowchart of one embodiment of the disassembly procedure.

The cathode ray tube 51 mounted on the transport pallet 2 while supporting the panel surface is first sent at a predetermined pitch and is located below the high-frequency heating device 24.

Thereafter, the cathode ray tube 51 is lifted to a predetermined position in the induction heating coil 25 by the CRT lifting means 23. Subsequently, the tab pressing means 21 descends,
Each of the four mounting brackets (tabs) 59 is 4 kg or more.
Pressing is performed with a pressing force of 6 kg.

Next, the high frequency heating device 24 is operated to heat the implosion preventing metal band 58 to 350 to 500 degrees Celsius. In this case, as the operating condition of the high-frequency heating device, 180 V, 200 A was applied at 1500 Hz to 2000 Hz for 15 seconds.

By this heating operation, the metal band 58 for preventing implosion rapidly rises in temperature and expands. As a result, the state becomes a “removable state” in a state opposite to that at the time of shrink fitting. In addition, the heat conduction from the implosion-preventing metal band 58 reduces the shearing adhesive strength of the resin impregnated in the non-combustible buffer material or the undercoated resin such as an acrylic resin, a polyester resin, or a urethane resin. Finally, the adhesive force of the resin falls below the pressing force, and the metal band 58 for preventing implosion is peeled off from the panel portion. The falling implosion-prevention metal band is indicated by a dashed line in the center of FIG.

Thereafter, the cathode ray tube from which the metal band for preventing implosion has been peeled is transported by a predetermined pitch. Then, the metal band for preventing implosion is removed from the transport pallet 2 in the next step.

Thereafter, a predetermined regeneration process may be performed individually on the cathode ray tube glass and the implosion preventing metal band.

FIG. 19 shows two examples of procedures for removing the implosion preventing metal band 58 from the transport pallet 2. In this case, it goes without saying that the steps of the flow are optional. Therefore, steps may be added, deleted, or changed as necessary.

FIG. 17 shows an example of a circuit diagram of an equivalent circuit of the high-frequency heating apparatus used in the above description and an example of a schematic configuration specification. The high-frequency output of the high-frequency heating device used in the present invention is 60 KW at maximum, and the frequency setting range is 0.5 kHz to 200 kHz.
It was set to about 0 kilohertz. It goes without saying that the output and the frequency may be set appropriately according to the inch size of the cathode ray tube to be handled. The lower limit output may be about 2 KW.

Further, as the CRT lifting means, any means such as an air cylinder or a robot may be used. The same applies to the transfer means of the transport pallet, which may be arbitrarily implemented, such as a roller conveyor, a belt conveyor, a roller conveyor, a chain conveyor, and a pusher system using a fluid cylinder.

Further, the tab pressing means is also optional such as an air cylinder and a compression coil spring. Further, the pressing load may be 4 kg or more per one place, and may be about 100 kg which does not break the cathode ray tube. Preferably 4
It is about 40 kg.

Further, the shape of the tip of the tab pressing means may be arbitrarily implemented. The tab pressing means shown in FIG.
An example using four independent pressing pins corresponding to each tab 59 is shown.

The tab pressing means shown in FIGS. 22 and 23 shows an example using a pair of T-shaped plates. As shown in FIG. 23, the T-shaped plate has both sides corresponding to the tabs cut out to a predetermined width. Next, the operation of the pair of T-shaped plates will be described with reference to FIG.

First, a pair of T-shaped plates are CRT51.
, And the CRT is positioned at a predetermined position in the horizontal direction. After this, release the clamping force,
(The holding position of the T-shaped plate is the same or slightly retracted.) The T-shaped plate is lowered in the vertical direction and presses the tab 59. The T-shaped plate presses two tabs per sheet (one side).

Next, another transport pallet according to the embodiment of the present invention will be described. FIG. 20A is a plan view of another transport pallet used in the metal band disassembly apparatus for preventing implosion of a cathode ray tube according to the present invention, and FIG. 20B is a plan view of FIG.
FIG. 21A is a cross-sectional view taken along S1 to S1, FIG. 21A is a plan view of another transport pallet of the present invention, and FIG.
FIG. 21B is a cross-sectional view of FIG.

The transport pallets 2A and 2B are made of wooden or A
20 and 21, which are formed of a metal member such as L or a resin member such as ABS or Duracon, have a substantially rectangular outer shape. In addition, the plate-like body is formed with predetermined recesses at four locations around it and through holes 24 and 27 at the center.

Further, in the case of the transport pallet 2A shown in FIG. 20, another large annular recess 25 is formed in a stepped shape at the peripheral edge of the upper end of the through hole 24, and a ring-shaped elastic member 26 is provided in the annular recess 25. Is fitted. The ring-shaped elastic member 26 is any one of a rubber member or a plastic member having a hardness of about 35 to 50 degrees or a combination thereof.

The rubber member may be any member such as silicon rubber, fluorine rubber, butyl rubber, urethane rubber, natural rubber and the like. Of course, it may be foamed in a sponge shape.

As for the plastic member, silicon-based plastic
Any material such as vinyl chloride, nylon, and styrene may be used.

The cathode ray tube (CRT) to be dismantled is mounted on the center of the transport pallet with the tube face down. (FIG. 20
(B), and the cathode ray tube is indicated by the two-dot chain line in FIG. 21 (B)).

Accordingly, the ring-shaped elastic member 26 is elastically deformed by the weight of the cathode ray tube, and comes into close contact with the surface of the cathode ray tube. As a result, when the transport pallet 2A is transported and stopped, the frictional force between the cathode ray tube and the elastic member 28 causes
The cathode ray tube 51 does not shift, and can maintain the initial mounting position state.

In the case of the transport pallet 2B shown in FIG. 21, a ring-shaped elastic member is used instead of the upper peripheral edge of the through hole 27.
The elastic member pieces 28 are arranged at substantially equal angles at the locations.

The constituent members of the elastic member piece 28 may be the same as those shown in FIG. In this case, since the cathode ray tube is supported at three points, the arrangement of the cathode ray tube is more stable than in the case of FIG.

When the transport pallet 2B is transported and stopped, the cathode ray tube 51 does not shift due to the frictional force between the cathode ray tube and the elastic member piece 19, and the initial mounting position can be maintained.

The outer shape of the transport pallet is not limited to the above embodiment, but may be in any form. Also,
The shape of the through-hole is not limited to the circular shape, and the shape may be any shape such as a rectangular shape.

According to the above embodiment, removal of the metal band for preventing implosion can be efficiently performed in a short time. In addition, large-scale equipment is not required. Further, the displacement of the cathode ray tube mounted on the transport pallet can be prevented.

"Step 10 / Dual panel measuring device" C
The presence or absence of the safety glass adhered to the panel surface of the RT is determined, and the CRT to which the safety glass is adhered is selected and transported to another process. Hereinafter, an embodiment of a CRT dual panel measurement device (CRT determination device) will be described with reference to FIGS.

FIG. 24 is a sectional view of a principal part of the concept of a process of measuring the outer shape of a cathode ray tube according to one embodiment of the present invention. FIG. 25 is a diagram illustrating measurement from a distance sensor to a fluorescent screen of the cathode ray tube according to one embodiment of the present invention. FIG. 26 is a flow chart (flowchart) of a cathode ray tube measuring step to a separating step according to an embodiment of the present invention.

As shown in FIG. 24, the cathode ray tube 51 from which the metal band has been removed has an image display surface (tube surface) at a predetermined position of the transport pallet 2 having a through hole 91 and a data carrier 92 at the center. It is mounted facing down.

Note that the transport pallet 2 is the same as that shown in FIGS.
It may be the same as the transport pallet described in 1 or may be a different type on another line.

In this state, at least one of the vertical and horizontal dimensions of the panel portion of the cathode ray tube 51 is set to the distance sensor 93.
Measured by Based on this measurement, the image display surface size (tube surface size) of the cathode ray tube is determined. Then, the measurement and judgment data are stored in a general memory means (not shown).

Next, as shown in FIG.
The measurement unit 95 provided with the measuring unit 4 is brought into contact with the image display surface.
Thereafter, the distance from the distance sensor 94 to the fluorescent screen of the cathode ray tube is measured.

In FIG. 25, the left side is a general cathode ray tube 51, which is not provided with a safety glass on an image display surface. The right side shows a specially designed cathode ray tube 51A provided with a safety glass via an adhesive 81 (for example, an unsaturated polyester resin).

The thickness of the safety glass is about 2 mm to 3 m.
m, the thickness of the panel image display unit is about 10 mm, the thickness of the adhesive is about 2 mm, and the distance between the image display surface and the distance sensor 94 is about 20 mm.

Therefore, the measurement distance differs by about 5 mm depending on the presence or absence of the safety glass. As a result, the measurement accuracy of the distance sensor 94 can be reduced, and an inexpensive sensor can be used.

It goes without saying that the distance sensor may be an arbitrary sensor such as a laser beam or an ultrasonic wave.

The measurement-separation process of the cathode ray tube will be described in more detail with reference to FIG. 26.
Measure the external dimensions of the cathode ray tube.

The distance a between a pair of laser distance sensors 93 facing each other is set to a predetermined value. Next, the distances b1 and b2 from the laser type distance sensor to the CRT are measured,
The external dimensions of the cathode ray tube are obtained from “c = a− (b1 + b2)”.

In step 2C, the distance between the fluorescent screens of the distance sensor is measured (measured) and the tube type is determined.

The measuring unit 95 is brought into contact with the image display surface of the cathode ray tube. Next, the distance to the fluorescent screen applied to the inner surface of the panel of the cathode ray tube is measured by the laser distance sensor 94.

Next, the distance “H value” between the distance sensor and the phosphor screen, which is input in advance to the computer, is compared with the distance (in the case of a cathode ray tube having no safety glass, the “H value” is defined by each inch size). Therefore, the “H value” is automatically set based on the external dimension information in step 1C).

If H is substantially equal to h1, it is determined that the cathode ray tube is a general cathode ray tube (no safety glass). If H <h2 and the difference is about 3 mm to 4 mm or more, it is determined that the cathode ray tube has safety glass.

In step 3C, data is transmitted. The determination result is stored in the mechanical data carrier 92 attached to the transport pallet 2. FIG. 25 shows a state where the data carrier 92 has been moved to the left.

It is needless to say that data may be stored and stored by using any means such as an optical type or a microwave type in addition to the mechanical memory shown in FIG.

In Step 4C, the cathode ray tube is separated into a general cathode ray tube and a cathode ray tube with safety glass. : Read data from data carrier and automatically transfer to another line in case of cathode ray tube with safety glass. This allows
The adhesive made of unsaturated polyester resin is prevented from entering the cullet.

Thereafter, through a step of removing the adhesive tape, in step 5C, the panel portion and the funnel portion are separated and processed.

A cathode ray tube without safety glass and a cathode ray tube with safety glass, in each line,
At the boundary between the panel part and the funnel part of the cathode ray tube, a disk-shaped diamond cutter is used to form a groove with a predetermined depth in a circular shape.

Next, the groove is heated and divided by utilizing the difference in thermal stress and thermal expansion between the panel and the funnel.

The disc-shaped diamond cutter has a diameter of 80 mm to 120 mm and a disc thickness of 0.2 mm to 2 m.
m, the number of rotations was about 2,000 RPM to about 10,000 RPM, and water was used as the cutting fluid. Groove depth is 0.2mm
２2 mm.

As described above, the method for determining a cathode ray tube according to the present invention can automatically specify the image display size of the cathode ray tube and automatically determine the presence or absence of the safety glass. In addition, the cathode ray tube is automated in the panel section and the funnel section with high productivity.

In the above embodiment, the description has been made for the purpose of reproducing an unspecified number of discarded video devices regardless of the manufacturer name, model name, product number, etc. of the video device.

[0130] When a code such as a number, a symbol, a bar code, or the like representing a product number, a model, or the like given to a housing of a video device or a cathode ray tube can be automatically recognized by a CCD camera or the like, a maker name, Needless to say, it is only necessary to perform the model name, the size determination of the cathode ray tube, the processing of the cutting groove on the housing, the determination and separation of the presence or absence of the safety glass of the cathode ray tube, and the division processing of the panel portion and the funnel portion.

[Step 11 / Automatic brushing device]
For the purpose of buffering and bonding the metal band for preventing implosion, the adhesive tape stuck to the side of the cathode ray tube is peeled off, or the adhesive and the adhesive of the adhesive tape are scraped off.

Hereinafter, a method and an apparatus (automatic bushing apparatus) for removing deposits on a cathode ray tube according to an embodiment of the present invention will be described with reference to FIGS.

DOO, 84 CRT pressing cylinder for holding the CRT between the suction pad, is 2 the CRT
And a transport conveyor 1 for transporting the transport pallet in a predetermined direction.

As the adhesive tape 72 for fixing the metal band and serving as a buffer, a glass cloth tape impregnated with an organic resin such as an acrylic adhesive is generally used.

The rotating brush 73 for peeling and removing the adhesive tape 72 is a steel wire having a wire diameter of about 0.2 mm to 0.8 mm,
Metal wires such as stainless steel wire and brass wire are radially densely planted on the surface of the hub. The outer diameter of the brush was about 200 mm, and the width of the brush was about 40 mm. In addition, the rotation speed of the brush is 3,000 RPM to 12,
It was made variable about 000 RPM. In addition, rotating brush 3
The direction of rotation can be switched between forward and reverse.

As shown in FIG. 29, in the apparatus of the present invention, rotating brushes 73A, 73B, 73C and 73D are arranged at four positions corresponding to the respective side walls of the CRT 51, and each of the wall surfaces is pressed by a predetermined pressing force. Abut

As shown in FIG. 30, the arrangement of the rotating brushes 73A to 73D in the vertical direction is sequentially different from the first peeling area to the fourth peeling area. That is,
The configuration was such that the adhesive tape could be reliably peeled over a width of about 100 mm.

Transport pallet 2 on which CRT is mounted and transported
Is provided with a through hole at the center thereof, which allows the CRT suction pad 75 to move up and down.

FIG. 31 shows the operation of the apparatus for removing adhering matter (adhesive tape) on the CRT wall surface configured as described above.
This will be described with reference to the flowchart shown in FIG.

First, the transport pallet 2 on which the CRT 51 is mounted is loaded into the cleaning chamber of the attached matter removing device 70 (step 1D).

Next, the transport pallet 2 is positioned at a predetermined position. Next, the lifting / lowering unit 77 is operated and the CRT

The panel surface is fixed by vacuum suction. At the same time, the CRT pressing cylinder 84 descends to press the vicinity of the neck portion of the electron gun of the CRT 51 and sandwich it between the CRT suction pad 75 (Steps 2D to 4D).

Next, the peeled adhesive tape collection box 82 is
Go forward to RT. The brush 73 is 10,0.
This is connected to the wall of the CRT 51 while rotating at about 00 RPM. In this state, the CRT 51 moves clockwise by 1 in the forward direction.
Rotate. Next, with the rotating brush 73 in contact, the CRT 51 is lowered by about 50 mm in the vertical direction (steps 5D to 8D).

Thereafter, the CRT 51 makes one revolution in the counterclockwise direction. During this time, the rotation direction of the brush 73 may be appropriately switched (step 9D).

Next, the collection box 82 and the brush 73 are placed on the CRT 5
Release from 1 and return to the original position. Next, the suction on the CRT valve surface is released, and the CRT suction pad 75 is lowered. Further, the CRT pressing cylinder 84 is raised. After this, C
The RT 51 is placed on the transport pallet 2 and carried out of the extraneous matter removing device (steps 10D to 13D).

In the above-described embodiment, C is used during the peeling operation.
By lowering the RT about 50 mm in the vertical direction and rotating it in the reverse direction, the peeling of the adhesive tape having a width of about 100 mm is further ensured.

Further, by switching the rotation of the CRT or the brush between the normal and reverse directions, the deformation of the brush tip can be prevented, and a new contact surface of the brush can always be obtained.

As a means for making a new contact surface of the brush always appear, a configuration using a dresser device shown in FIG. 32 may be used. In this case, the dresser 62 made of a porous body such as a porous ceramic or a grindstone is brought into contact with the tip of the brush to grind the tip of the brush. At this time, water and the like are used in combination as the grinding fluid to improve the cooling action and the grinding effect.

In the above embodiment, it is needless to say that the planting width and outer diameter of the brush, the material of the wire, the number of revolutions, and the like may be arbitrarily set. The presence or absence of a dresser device is also optional. Further, the same applies to the configuration in which the rotating brush side is moved up and down instead of the CRT lowering in step 9D.

As described above, according to the present invention, a deposit such as an adhesive tape remaining on the side surface of a valve of a CRT is dry-processed.
It can be efficiently removed in a short time.

[Step 12 / CRT transfer device] The CRT from which the electron gun, the metal band, the adhesive tape and the like are released is separated into a panel portion and a funnel portion by the CRT transfer device (12) in FIG. It is transported to the process.

As described above, in the embodiment of each of the above steps,
The object to be dismantled is not limited to a video device (television receiver, personal computer, display monitor, or the like), but may be any electronic device such as an audio device or an earphone.

[0153]

As described above, according to the present invention, household appliances such as television receivers can be dismantled dry. Further, the steps from removal of the back cover of the housing to peeling and removal of the adhesive tape stuck to the side surface of the CRT can be automated or semi-automated with simple equipment, thereby facilitating the separation and regeneration process. As a result, the recycling rate is improved, which contributes to environmental conservation and effective use of resources.
