Abstract

PROBLEM TO BE SOLVED: To facilitate to remove a display device by providing a heat means to heat and expand a mount frame to form a gap between a mount frame and the display device, a display device moving means to move the display device from the mount frame and a means carrying the display device. SOLUTION: A heat means 30 is arranged corresponding to a separate extract position PL2. When a high frequency power is supplied to an inductor 34 from a power supply section 120, a mount frame 230 causes self-heating through the reception of magnetic flux from the inductor 34 based on a current generated in the inside and a resistance of a material of the frame 230. Thus, a temperature rise causes in the frame 230, which is expanded and a gap is produced between the frame 230 and a side surrounding of the cathode ray tube 200. A carrying means 80 lifts up only the tube 200 after the frame 230 is heated by the means 30 to carry the tube from the position PL2 up to an eject position PL3. A display device moving means 50 has a push-up means 51 and a lift-up block means 52 and the means 51 lifts up the tube 200 from the frame 230 after the means 30 heats up the frame 230 to separate the tube 200 from the frame 230.

As a method of separating the mounting frame from the cathode ray tube, there is a method of cutting the mounting frame with a cutter. However, this method may damage the cathode ray tube when cutting the mounting frame, and thus has a problem that it is difficult to safely remove the cathode ray tube. Further, there is a method in which a cathode is detached from the mounting frame by applying a conductor to the mounting frame made of metal and directly supplying electric power to the mounting frame via this conductor, whereby the mounting frame is thermally expanded. is there. However, in this method, the heating effect of the mounting frame varies depending on the contact state of the conductor (power feeding portion) contacting the mounting frame, and thus there is a problem that the heat treatment work is difficult to manage.

By simply automating the separation and disassembly of the cathode ray tube and the mounting frame, which is normally done by the operator, the operator can judge the cathode ray tube, the mounting frame and the cabinet of various models, and separate them according to their size. It is necessary to carry out a treatment, and if the cathode ray tube, the mounting frame and the cabinet are not positioned at that time, it cannot be separated and disassembled well, and the separation and disassembly takes a long time.

Even when the operator removes the cathode ray tube with his eyes and holds it, if the cathode ray tube has a different size,
It cannot be held securely, and there is a risk that the cathode ray tube will be broken when it is removed from the mounting frame. In the dismantling work of the cathode ray tube, mounting frame and cabinet,
Since the worker may injure his body due to the influence of dust, noise, etc., he must use dustproof and soundproofing equipment, and the efficiency of the worker's work of removing the cathode ray tube such as a television set is poor. Therefore, the present invention has been made to solve the above problems, and provides a device for removing a display device and a method for removing the display device, by which the display means can be reliably and easily removed from the mounting frame according to the type. The purpose is to do.

Next, a method of removing the display device by the above-described display device removing device will be described. The feeding means BP of FIG. 1 is a conveyor 300 of the transfer and positioning means 300.
Cabinet 702 is sequentially loaded into a. The cabinet 702 includes a mounting frame 230 and a cathode ray tube 200.
Contains. Cabinet 702 is, for example, a discarded television set cabinet.

The cabinet 702 is placed with the neck portion 200N of the cathode ray tube 200 facing upward, as shown in FIGS. When the cabinet 702 reaches the size detection position PL1 of FIG. 1, the stopper 13 projects and stops at the size detection position PL1 of the cabinet 702. The camera 12 of the XY traveling robot 11 moves in the X direction and the Y direction to read the positions of the holding fittings 11a, 11b, 11c, 11d of the mounting frame 230 in the X direction coordinate and the Y direction coordinate. Thereby, the control unit 10
0 confirms the size of the cathode ray tube 200.

Next, the cabinet 702 at the size detection position PL1 in FIG. 1 is moved in the arrow ST direction by the operation of the conveyor 300a of the transfer and positioning means 300, and reaches the separation / takeout position PL2. At this time, FIG. 1 and FIG.
The light L of the light emitting portion 302 of the positioning sensor 301 is blocked by the neck portion 200N of the cathode ray tube 200, and the light receiving portion 30

2 is positioned with respect to the separation and extraction position PL2. That is, the positioning of the cathode ray tube 200 at the separation and extraction position PL2 can be performed using such a positioning sensor 301, or can be performed using a positioning jig that can be adjusted according to the size of the cathode ray tube 200. Of course you can. The neck portion 200N, which is the center of the cathode ray tube 200, is thereby positioned substantially at the center of the separation extraction position PL2.

Next, the inductors 34, 34 of the heating means 30 shown in FIGS. 2 and 4 approach the mounting frame 230. That is, the vertical movement actuator 31 lowers the front-back drive actuator 32 in the arrow Z (Z1 direction), the front-back drive actuator 32 moves the lift actuator 33 in the arrow FB direction, and the lift actuator 33 moves the inductor 34 in the arrow Z1.
By slightly lowering in the direction, the inductor 34 is positioned at a position facing the mounting frame 230 as shown in FIG.

It is arranged with a gap C in b.

The induction heating power supply unit 120 shown in FIG.
When high frequency power is supplied to the inductors 34, 34 from the inductors 34, 34, the mounting frame 230 receives the magnetic flux from the inductors 34, 34, and the current generated inside the mounting frame 230 and the resistance of the material of the mounting frame 230 The value causes self-heating. From this,
The mounting frame 230 rises in temperature and expands. That is, the thermal expansion coefficient of the metallic mounting frame 230 and the glass cathode ray tube 20
By utilizing the difference in coefficient of thermal expansion of 0, the mounting frame 230 can be separated from the side surface periphery of the cathode ray tube. As a result, the mounting frame 23
0 is the cathode ray tube 20 with an interval E as shown in FIG.
You will move away from zero.

When the heating means 30 heats the mounting frame 230, in order to hold the cathode ray tube 200 so as not to fall, the pushing-up means 51 of the display device moving means 50 shown in FIGS. 3 and 6 is used.

In order to prevent the radiant heat from the mounting frame 230, cooling air is supplied from the cooling nozzle 56, and the temperature difference between the cathode ray tube 200 and the mounting frame 230 is kept appropriate.

Next, the cathode ray tube 200 is separated and removed from the mounting frame 230 by the operation of the display device moving means 50 shown in FIG. That is, the vibrator 57 causes the cathode ray tube 20 to
0 is applied, and the pusher plate 55 of the push-up means 51 is further raised in the direction of arrow Z2, as shown in FIG.
The cathode ray tube 200 is completely moved upward from the mounting frame 230 as shown in FIG. In this case, in order to prevent the mounting frame 230 and the cabinet 702 from being lifted at the same time, the pin 65 of the lifting preventing means 52 in FIG. 9 extends to support the upper edge of the mounting frame 230. By doing this,
Even if the gap E is small, the cathode ray tube 200 can be reliably and immediately separated from the mounting frame 230 and taken out.

As shown in FIG. 11, when the cathode ray tube 200 is lifted along the direction of arrow Z2 and the cathode ray tube 200 is lifted and held at the lifting position PL4, the carrier means 80 shown in FIGS. 1 and 6 is gripped. The tools 83a, 83a face two diagonal corners CN of the cathode ray tube 200. And the control unit 100
Is the cathode ray tube 20 with respect to the actuators 86, 86.
Since the command signal corresponding to the size of 0 is given, the actuator 86 moves the receiving members 87, 87 in the facing direction by the distance corresponding to the size of the cathode ray tube 200. As a result, the receiving member 87 can receive the diagonal corners CN, CN of the cathode ray tube 200 as shown in FIG.

When the motor 83 shown in FIG. 6 is operated,
The support beam 82 moves in the direction of the arrow Y1 and the cathode ray tube 200 moves to the discharge position PL3. In this state, the cathode ray tube 200 is mounted on the mounting plate 4 of the discharge lifter 401.
Since it is located above 04, the mounting plate 404 is lifted by the operation of the actuator 403 to move the mounting plate 404.
Receives the cathode ray tube 200. At this time, the gripping tool 83
The cathode ray tube 200 is mounted on the mounting plate 404, because the receiving members 87, 87 of a, 83a move in the direction to separate from each other. After that, the actuator 403 of FIG.
04 moves down in the direction of arrow Z1, and the actuator 406 operates to push the cathode ray tube 200 from the mounting plate 404 to the discharge conveyor 402 by the pusher 407. The cathode ray tube 200 transferred to the discharge conveyor 402 is sent to the cathode ray tube processing unit 700.

On the other hand, the mounting frame 230 and the cabinet 702 left after the cathode ray tube 200 is removed are sent to the next processing unit RP along the sending direction ST by the transfer and positioning means 300 of FIG. Processing is performed. As described above, in the embodiment of the present invention, the cathode ray tube 2
00 is mounted and mounted on the cabinet 702 using the mounting frame 230.
Then, the size of the cathode ray tube 200 is detected, and then the heating means 30, 30 is used to remove the cathode ray tube 20 from the mounting frame 230.
Remove only 0. The removed cathode ray tube 200 is sent to the discharging means 400 side using the display device moving means 50 and the transporting means 80, and the discharging means 400 is connected to the cathode ray tube 200.
Only is sent to another processing unit 700. And the remaining mounting frame 2
30 and the cabinet 702 are processed by the processing unit RP of the next stage.

Thus, the work of separating and removing the cathode ray tube can be automatically performed without the intervention of an operator, and the work can be efficiently performed. Even if a worker is required, it is sufficient if there is a worker who manages the removal device of the present invention, work safety is ensured, quality of the cathode ray tube removed and quality for reproduction of cabinet and mounting frame. Can be guaranteed. Since the size of the cathode ray tube is detected in advance, it is not necessary to judge the size of the cathode ray tube by the operator's visual observation as in the conventional case, the workability is improved, and the operator needs to separate and take out the cathode ray tube directly. Since it does not exist, it is not necessary to prepare dustproof equipment or soundproof equipment for that purpose. Further, since the size of the cathode ray tube is detected in advance, it is possible to perform an appropriate work of separating and removing the cathode ray tube according to the size of the cathode ray tube.

The present invention is not limited to the above embodiment. For example, although a cathode ray tube (CRT) is taken as an example of the display device, the present invention is not limited to this. For example, if the display device of the cathode ray tube made of glass is removed from the mounting frame of the cabinet (main body), the present invention Can be applied. The means for heating the mounting frame is not limited to the induction heating method, and other methods can be adopted. For example, it is possible to directly supply power to the mounting frame to directly heat the mounting frame.
