[0004]

By the way, as an apparatus for disassembling such a television set, the television set is placed on a flat conveyor, and the flat conveyor is moved to convey the television, thereby disassembling the television set. Workers disassemble television sets on a flat conveyor in sequence and discharge dismantled parts and waste materials. However, if the television set is disassembled while being transported using such a generally used flat conveyor, the following problems occur. (1) Residual waste material, dust, and the like adhere to the flat conveyor, and the flat conveyor does not move. (2) The dust or the like adhering to the flat conveyor adheres to the cathode ray tube of the television set to be conveyed, and when the cathode ray tube is conveyed to the next step in that state, the cathode ray tube is cut or separated. It is necessary to clean the cathode ray tube before the operation. (3) When a cathode ray tube of a television set is transported using a flat conveyor, the platen is transported by placing the television set on the flat conveyor and placing the television set on the platen. It is necessary, and after the disassembly of the television set, an operation of collecting the platen is required. Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a disassembly device for a display device which can disassemble a display device including a cathode ray tube smoothly without requiring an auxiliary tool such as a platen.

[0005]

According to the present invention, there is provided a disassembly apparatus for disassembling a display device provided with a cathode ray tube, which is disposed on an upper portion and disassembles components of the display device. This is achieved by a disassembly device for a display device, comprising: a dismantling work section for collecting a display device disposed below the dismantling work section for collecting components of the display device disassembled by the dismantling work section. .

[0006] In the present invention, the dismantling work section is disposed at the upper portion, and the components of the display device are dismantled in the dismantling work section. The collection unit is disposed below the disassembly operation unit, and the components of the display device disassembled by the disassembly operation unit are collected by the collection unit by its own weight. In the present invention, the components of the display device disassembled in the disassembly operation unit can be accommodated in the collection box of the collection unit via the duct. Thereby, the components of the display device can be reliably collected without jumping out. In the dismantling work department,
Since the display device is conveyed with the cathode ray tube side facing down and inclined, the operator can more easily remove additional components added to the cathode ray tube of the display device.

[0007] The transporting means has a gap for dropping the components of the display device and the dust to the collecting section side during the disassembly, so that the components and the dust do not accumulate on the transporting means. It is possible to prevent dust and the like from adhering to the cathode ray tube of the display device. As the conveying means having such a gap, a driving roller supporting the upper side of the cathode ray tube of the display device of the roller conveyor and a rotating roller supporting the lower side of the cathode ray tube are used. When the cathode ray tube is removed from the cabinet in the disassembly work section, the holding state changing means holds the cathode ray tube in an inclined state or a horizontal state. Then, the cathode ray tube extracting means suppresses the cabinet when the cathode ray tube is removed from the cabinet, and raises the cathode ray tube from the cabinet. Thereby, the cathode ray tube can be removed from the cabinet in the dismantling work section.

0 and the crushing apparatus 500 of FIG. 7 are arranged in the cathode ray tube processing unit 3 of FIG.

Next, the collecting section 2 shown in FIG. 1 will be described.
The collecting section 16 disposed below the dismantling section 6 of the dismantling work section 1 shown in FIG. 3 has a member discharge duct 15 and a dust discharge duct 16. The dust discharge duct 16 is located below the transporting means 20, and the outlet of the dust discharge duct 16 is connected to the middle of the member discharge duct 15. The member discharge duct 15 can also apply vibration to members and dust passing by the vibrator 17. By doing so, dust and dismantled members can be smoothly collected in the collection box 51 of the collection unit 16. A plurality of collection boxes 51 are arranged in the Y direction as shown in FIG. 1, and a transparent or translucent sheet 52 is provided so as to cover them. The sheet 52 is for reducing noise and preventing dust and members from being released to the outside. Therefore, the sheet 52 is provided so as to cover the collection box 51 from the frame pair 13. As described above, the crushed material recovery section 460 of the recovery section 2 has the containers 548, 548.

Also in this case, the sheet 52 is provided, so that the crushed pallet (crushed material) of the funnel portion 211 can be prevented from jumping out and noise can be prevented from being emitted outside.

Next, an example of a dismantling operation by the dismantling device of the above-mentioned display device will be described. The disassembly apparatus shown in FIG. 1 includes a display device having a used or failed cathode ray tube, for example, a television set, a monitor of a computer, or the like, and a component (disassembly element) such as a cathode ray tube, an electron gun, a deflection yoke, and a substrate. Used to perform recovery. As described above, in the dismantling apparatus of the present invention, the dismantling work section 1 is located at the upper portion, and the disassembled components generated by the dismantling work are collected by the collection section 16 such as the dismantled parts of the collection section 2. And the funnel 2 of the crushed cathode ray tube
11 is collected in the crushed material collection unit 460.

First, the display device D is set in the loading section 5 from the stock section 4 in FIG. Then, the display device D is lifted by the crane 5a to the dismantling section 6. Thus, the number of display devices D passing through the counting unit 8 is counted. Then, the display device D is mounted on the driving roller unit 21 and the rotating roller unit 22 of the transport unit 20 by the crane 5a as shown in FIG. In this state, the cathode ray tube 200 of the display device D is positioned obliquely downward, and the roller 213 is moved to the display device D.
Support the upper side of the cathode ray tube 200,
Free roller 233 supports the lower side of the cathode ray tube 200. When the motor 204 operates, the rollers 213
Moves the display device D in the Y1 direction. At this time, after the display device D is stopped at a predetermined position in the station by a stopper (not shown), the pusher 24 is operated, and the display device D is further lifted to the dismantling worker M side. As a result, the display device D is separated from the roller 213 of the drive roller unit 21 and the display device D is lifted in the G direction with the free roller 233 as a fulcrum.

In this state, the dismantling worker M dismantles the display device D. The rear cover 702b is removed from the cabinet 702, and the deflection yoke, the electron gun, the substrate, and the like are sequentially separated at predetermined dismantling stations.
Is dismantled by hand. For example, at the dismantling station of the dismantling section 6 corresponding to the first collection box 51 in FIG. 1, the rear cover 702b is removed and collected in the first collection box 51 via the member discharge duct 15. .
At the position of the disassembly station corresponding to the next collection box 51 in FIG. 1, the deflection yoke is removed from the cathode ray tube, and the deflection yoke is connected via the member discharge duct 15 to the second collection box 51.
Will be collected. Similarly, electron guns, substrates, and the like are sequentially collected in the third collection box 51 and the fourth collection box 51.
In this case, each member discharge duct 15 is connected to the vibrator 1
Since the vibration is applied by 7, the disassembled component does not become clogged in the member discharge duct 15. The display device D to be dismantled by the transport means 20
, The fine dust, dust and the like pass between the transfer means 20 and between the pedestals 23, 23 and the dust discharge duct 1
6. Each corresponding collection box 51 via the member discharge duct 15
Can be recovered. For this reason, all the dust and dust can join the member discharge duct 15 and be collected in the collection box 51 without stopping on the transporting means 20 due to dust or dust generated at the time of disassembly.

Next, in the display device D, the front cabinet 702a and the cathode ray tube 200 are already left. In this state, the display device D moves to the separation device of the cathode ray tube processing unit 3 shown in FIGS. In FIG. 4, the display device D is a free roller 32.
5, one end is mounted, and the other end is
05 on the rotating roller 313. At this time, the drive cylinder 332 is operated and the clamp claw 3 of the clamp portion 315 is moved.
31 is engaged with the side of the front cabinet 702a.
With the display device D fixed in this way, the electric cylinder 340 is contracted and the inclined plate 330 is moved to the position shown in FIG.
The holding state is changed from the inclined state to the horizontal state in FIG.

Incidentally, as shown in FIG.
0, a slider 330b is provided via a roller 330a.
Is built-in. The slider 330b is connected to the drive cylinder 332, and when the drive cylinder 332 contracts, the slider 330b moves the inclined plate 3
30 through the roller 330a, the clamp portion 315 integrated with the slider is moved by the arrow E.
By moving in one direction, the clamp claws 331 can engage with the front cabinet 702a. At this time, since the motor 318 is stopped, the display device D does not move in the Y1 direction.

Next, the electric cylinder 401 of the cathode ray tube take-out means 400 is operated to attach the suction pad 402 to the cathode ray tube 2.
At the same time, the cathode ray tube 200 and its explosion-proof band are lifted in the direction of the arrow Z1. Thereby, the front cabinet 702a, the cathode ray tube 200, and the explosion-proof band are separated. Before this operation, the screws for attaching the explosion-proof band have been removed, and the explosion-proof band and the front cabinet 702a are separated. Note that the electric cylinder 401
Point setting lever 4 with clutch brake related to
90 performs the following operation. When the point adjusting lever 490 with the clutch brake is released, the cathode ray tube 20 is released.
It can be manually operated so that it can be easily adjusted to the center of zero. (The brake is released when the ball is grasped, and the ball is normally fixed.) At this time, if the self-view of the neck tube portion and N is determined, the left and right positions are easily aligned from the operator's side if the neck tube portion and N are viewed. For front and rear center alignment, an antenna is provided on the cylinder 401 having the suction pad 402 to assist in pad alignment. Thus, the cathode ray tube 200 is connected to the front cabinet 7.
At the time of separation from 02a, the operation of the motor 318 is stopped. The separated cathode ray tube 200 and explosion-proof band are transferred to the dividing device 420 of FIG.

On the other hand, the separated front cabinet 702a
Returns from the horizontal state in FIG. 5 to the inclined conveyance state in FIG. 4 to hold the inclined plate 330 of the conveyor, and at that time, the clamp claw 331 is retracted in the direction of E2 to release the fixing. Is transported to a predetermined discharge position.

In FIG. 6, a splitting device 420 cuts the cathode ray tube 200 along the cutting line LL on the panel section 210 and the funnel section 211 side. The panel section 210 is sent to another section as shown in FIG. 2 and performs necessary processing. On the other hand, the funnel unit 211 having the aperture grill 229 is sent to the crushing apparatus 500 shown in FIG. When the funnel section 211 of FIG. 6 is inserted into the input port 540 of the crushing apparatus 500 and the funnel section 211 rides on the lower mold 512 and the upper mold 511 descends in the direction of Z2, the upper mold 511 and the lower mold 512 crush the funnel portion 211. After the crushing, when the lower cylinder 512 rotates in the F direction by operating the rotation cylinder 530, the crushed material of the funnel unit 211 is collected in the container 548 of the collection unit 460. When the panel portion and the funnel portion are in a mixed state or cannot be separated, they are crushed and collected by the crushing device 500 of FIG. When the collection is completed, the rotation cylinder 530 contracts again, so that the lower mold 512 rotates in the direction opposite to the direction F and stops the stopper 5.
It rests on 39 and stops in a horizontal state.

Incidentally, the present invention is not limited to the above embodiment. In the above-described embodiment, the funnel portion is crushed by the press in the crushing device 500. However, the present invention is not limited to this, and another method, for example, a method in which the funnel portion is crushed by being sandwiched between rollers can be adopted. In the above-described embodiment, as shown in FIGS. 3, 4, and 5, the driving roller unit 21 and the driving roller unit 305 can be provided with motors corresponding to the respective rollers and can turn on / off the respective motors independently. Although a method that can be used is adopted, the present invention is not limited to this, and it goes without saying that the lower rotating roller unit 22 or 310 may be driven. The pusher 24 in FIG. 3, the electric cylinder 340 in FIG. 4, the drive cylinder 332, and the electric cylinder 401 in FIG. 5 are of an electric type. However, the invention is not limited thereto, and a hydraulic cylinder such as a hydraulic cylinder or a pneumatic cylinder may be used. It can also be used.

In the present invention, the display device is transported by a combination of a drive roller located at the upper part and a rotary roller located at the lower part so that the display to be dismantled can be transported in an inclined state. And a conveying means 2 which is a conveyor
The central portion of the space 0 has a space between the pedestals 23, 23, so that generated dust and dust can be naturally dropped and collected in the collection box 51 via the dust discharge duct 16 and the member discharge duct 15. ing. For this reason, there is no possibility that dirt, dust, and the like adhere to the conveyor and remain, and the cleaning process of the conveyor can be omitted to increase the rotation efficiency and the like.

The driving roller unit 21, the driving roller unit 305,
The rotation roller unit 22 and the rotation roller unit 310 are roller conveyors, so that the display device can be transported without preparing a platen for mounting the display device, and the equipment area can be reduced by eliminating the platen collection process. As a result, the number of steps can be reduced, and the cost can be reduced. As shown in FIG. 1, since the disassembly work unit 1 is located at the upper part and the collection unit 2 is located at the lower part, trash and dust generated in the disassembly work unit 1 and the disassembled components and the like are collected by the collection unit 2. There is a great merit that each predetermined collection box can be naturally dropped by gravity and collected.
