DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. For convenience, a video device is shown by an example of a television receiver.

(Embodiment) FIG. 1 is a flowchart (flowchart) of a television receiver disassembling process according to one embodiment of the present invention, FIG. 2 is a plan view of a main part of a housing disassembling apparatus according to one embodiment of the present invention, FIG. 3 is a side view of a main part of FIG. 2, and FIG.
FIG. 5 is a perspective view of a process of forming a U-shaped cutting groove, and FIG. 5 is a perspective view of a state in which the processing of the cutting groove is completed and a bottom surface (bottom plate) is opened.

The television receiver 1 shown in FIGS. 1 to 5
00 is a CRT 51 (cathode ray tube / CRT) and C
A housing (cabinet) 50 screwed to the outer peripheral surface (end surface) of the RT 51, a chassis (control circuit unit) 52 housed in the housing 50, a speaker device 55 disposed near the CRT 51, and attached to a side plate Printed wiring board 5
3, 57, etc.

The CRT 51 is, as shown in FIG.
A metal band 58 (explosion-proof reinforcing band) is wound around the outer peripheral surface (the end surface of the display screen section) in a predetermined manner, and mounting brackets 59 are provided at four places by means such as spot welding.

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

FIG. 1 shows “cut groove processing → disassembly →
FIG. 2 shows a state in which a waste television is mounted on the transport pallet 2 and transferred to a fixed position, that is, step 2.

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

Then, the housing 50 of the discarded television is moved to the X-axis and Y-axis.
Positioning is performed in the axial direction (position determination / step 4). Positioning of the housing 50 in the Y-axis direction is performed by two air cylinders 4 and 4 facing each other 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, air cylinders 7 and 7 that move up and down in the Z-axis direction, air cylinders in the X-axis direction (not shown), and plates 8 and 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 5 / main surface position measurement).

The measurement of the main surface position is performed in preparation for the cutting groove processing in the next step 6, 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 6, each main surface of the housing 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- to five-axis control robot, for example, a scalar type robot.

The number of revolutions 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 set at about 00 RPM to 10,000 RPM.

FIG. 4 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 rotary 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. 5 shows a state in which the bottom surface of the housing is opened. Thereafter, steps 7 and 8 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). Subsequently, the cathode ray tube, the chassis, the printed wiring board, the speaker device, and the like are removed by robot means (not shown) (none is shown),
Thereafter, it may be transferred to the separation / regeneration processing step (step 9).

It is desirable that the operation of opening and closing each main surface of the housing 50 and the operation of removing each constituent member be 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. 1, the steps may be interchanged, added, or deleted.

Further, it goes without saying that the shape and position of the cut groove formed in a 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 formed not only on the bottom surface but also on the top surface and both side surfaces, the housing is rotated at every 90 degrees by a housing rotating means (not shown) → the main surface position measurement → cutting The above procedure may be repeated. FIG. 6 shows a disassembled state in which four main surfaces of the housing 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 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.

[0043]

As described above, the disassembling method and apparatus for disposing of discarded video equipment according to the present invention can be automated for disassembling work by the above-mentioned configuration. In addition, the separate reproduction process after disassembly is facilitated. As a result, the recycling rate is improved, which contributes to environmental conservation and effective use of resources.
