Hereinafter, the step of each process shown in FIG. 3 is demonstrated. Reference numerals 1 to 9 shown in Fig. 2 indicate respective step numbers.

(a) "Stem 1 / input device"

Step 1 mounts and disposes the waste television receiver on the conveyance pallet by the input device.

In this embodiment, it mounted on the conveyance plate manually. Of course, a process of automatically detecting a waste television receiver conveyed by a conveying conveyor or the like and automatically mounting the conveying pallet on a conveying pallet by a feeding device is also possible. As the lifting robot of the waste television set, the CRT tube can be vacuum-adsorbed, or both sides of the cabinet can be sandwiched by two arms.

(b) "Steps 2 to 4 / Tilt device to Cleaning device to Tilt device"

In step 2, a conveyance pallet carrying a television receiver is carried into the worktable of two inclined worktables which are not conveyed yet. The worker removes the back cover of the cabinet located on the back side of the cabinets constituting the television receiver.

In step 3, dust collected in the waste television set is automatically removed by an air blow.

In step 4, the television receiver is then removed from the worktable which can be tilted again together with the conveyance pallet, and the deflection coil DY, the chassis, and the like are removed manually.

The member which removed the back cover, DY, etc. is mounted on the rear conveyance conveyor, and is automatically carried out by predetermined | prescribed.

4 to 8, an embodiment of the isola device and the cleaning device will be described.

Fig. 4 is a side view of the concept of the tiltable worktable and cleaning device constructed in this embodiment. 5 is a plan view illustrating main parts of FIG. 4. 6 is a side view of the main portion of the tiltable worktable. FIG. 7 is a plan view of FIG. 6. 8 is a side view of main parts of the cleaning apparatus.

In FIG. 4 and FIG. 5, the television receiver 100 is mounted on the conveyance pallet 2, and is conveyed by the conveyance conveyor 1 from the left side to the right direction of FIG. The television receiver 100 having the cabinet 101 and the back cover 102 which has been conveyed to the front of the work table 40 (the left side of FIG. 5) is an automatic transfer device, for example, from the conveying conveyor 1. The conveyor pallet 2 is moved together with the conveyance pallet 2 on the tiltable first work bench 40 by a belt conveyor device or the like (not shown) which is driven in a direction orthogonal to the chain conveyor which is tightened in parallel.

The operator is located immediately in front of the tiltable worktable 40. After the operator confirms that the television receiver 100 has been moved, the start signal is held by pressing a foot switch (not shown), etc., and the work bench 40 is tilted at a predetermined angle, for example, in the range of 45 ° to 75 °. Let's do it.

The television receiver 100 mounted in the center of the work platform by the inclination of the work table 40 slides on the conveyance pallet to abut the stopper 32, or is located within the reach of the operator. Here, the worker removes the back cover 102.

After the work is finished, the work bench returns to the horizontal state, and the conveyance pallet 2 equipped with the television receiver is returned on the conveying conveyor 1 again by the automatic transfer device. The returned television receiver is carried into the cleaning apparatus 45 of the next process by the conveyance conveyor 2.

In addition, in the case of a small television receiver of about 14 inches to 20 inches, it is possible to work in a horizontal state without tilting the work table 40.

Moreover, even in the case of a large size television set, it is set as the structure which an operator can set an inclination angle arbitrarily according to a form and an appearance.

In FIG. 5, two work benches 40 are arranged before and after the cleaning device 45.

This first reason is to give a wide range of dismantling capability of the television receiver. In other words, this configuration makes it possible to increase the number of people according to the throughput.

The second reason is that if the next television receiver to be dismantled has been conveyed while the dismantling work is being performed on one of the two adjacent work benches, the conveyed television receiver can be accepted on the other work bench. In other words, the time required for disassembly varies depending on the size and type of the television receiver. Therefore, when it takes longer than a certain processing time, the other work bench of two work benches becomes a preliminary reception place. In this case, of course, the worker moves to the next workbench and works.

Next, the configuration of the tiltable worktable 40 will be described in detail with reference to FIGS. 6 and 7.

6 and 7, the work table 40 is mounted on the base frame 31, the parallel conveying belt conveyors 39 and 39 assembled in the frame 31, and the lower surface of the frame 31. It consists of a drive cylinder 33 and a base frame 34.

The conveying belt conveyor 39 is composed of two belts in parallel, and the belt conveyor 39 conveys the conveying pallet 2 to the vicinity of the stopper 32 and automatically stops.

The frame 31 is hinged so that one end part can be rotated by the bearing 35 and the shaft 36. On the other end side of the frame 31, a rod end member of the cylinder 33 is hinged via the shaft 37.

The other end of the cylinder 33 is attached to the frame 34 via the shaft 38.

In this way, each support point comprises the link mechanism which can be rotated. With this configuration, when fluid pressure such as air or hydraulic pressure is supplied to the cylinder 33, the piston rod of the cylinder moves, and the frame 31 is inclined at a predetermined angle. In addition, the television receiver 100 or the large television receiver 100A is mounted on the pallet 2.

In addition, as a means to incline the frame 31, it can be said that it may be set as arbitrary structures other than the above. For example, an eccentric disk may be attached to the motor shaft to tilt the plate. Moreover, you may make it the structure which inclines a plate with a cam mechanism etc. (all are shown).

Next, the cleaning process will be described. In FIG. 8, the television receiver 100 mounted on the conveyance pallet 2 and conveyed at a predetermined position by the conveyance conveyor 1 with the cabinet 101 and the CRT 103 is a sealed box which is lowered from the upper side ( 46) the surroundings are closed in a substantially airtight state. A spray nozzle 47 and an exhaust duct 48 are disposed near the ceiling of the sealed box 46. In this way, the cleaning device 45 is configured.

Thereafter, the high pressure air shower 49 is ejected toward the television receiver 100 from the plurality of spray nozzles 47 disposed near the ceiling.

The high-pressure air shower 49 blows dust attached to and deposited on the component parts such as the electron gun neck portion, the DY portion, the funnel portion of the CRT, the inner surface of the cabinet, and the printed wiring board and wiring housed in the cabinet.

At the same time as air is blown out, the exhaust duct 48 is also operated, and the flying dust is sucked in and discharged. The air blowing time was set to about 5 seconds to several tens of seconds.

After the cleaning of the television receiver is finished, the sealed box is raised, and the television receiver mounted on the conveyance pallet 2 is sent to the next step by the conveyance conveyor 1.

In the next step, the television receiver is again sent to the second worktable (the worktable disposed on the right side of the cleaning apparatus in FIG. 5) with the conveyance pallet. In the second work table 40, the DY part (polarizing coil, neck printed circuit board, etc.) attached to the neck part of the CRT and the chassis are separated.

In addition, in the separating step of the DY part, since the inside of the television receiver is cleaned in advance, the flying of dust is greatly reduced, and therefore, does not adversely affect the working environment and the equipment.

After the separation of the DY section or the like, the CRT mounted on the back cabinet is sent to the cabinet cutting step and the CRT take-out step of the next step by the transfer conveyor together with the transfer pallet.

As described above, according to steps 2 to 4 of FIG. 3, the back cover and the DY portion can be separated, and dust in the backkit can be efficiently carried out, and the dismantling work after the next step can be automated.

The tiltable workbench is also capable of efficiently preprocessing multi-inch and sized television sets.

(c) "Step 5 / bottom plate cutting device"

Step 5 cuts the bottom plate of the wooden cabinet into a U shape, and makes it easy to take out the CRT.

Hereinafter, an embodiment of a bottom plate cutting (cabinet dismantling) device of a cabinet will be described with reference to FIGS. 9 to 14. 9 is a flowchart (flow chart) of the disassembly process of the television receiver in one Embodiment of this invention. 10 is a plan view of main parts of the cabinet disassembly apparatus according to the embodiment of the present invention. 11 is a side view of the main portion of FIG. 10. 12 is a perspective view of a process of processing a U-shaped cutting groove in the periphery (bottom surface / bottom plate) of the cabinet to dismantle the cabinet of the imaging device. Fig. 13 shows a perspective view of a state where the bottom surface (bottom plate) is opened after finishing the cutting groove. 14 shows an exploded state in which four main surfaces of the cabinet are opened.

The television receiver 100 shown in FIGS. 9 to 13 includes a cathode ray tube 51 (also called a CRT or a CRT), a cabinet 50 non-fastened to an end surface of the outer circumferential surface of the CRT 51, and a cabinet ( 50 mounted on a chassis (including a control circuit) 52, a speaker device 55 disposed near the CRT 51, an antenna terminal plate 54, a tuner 56, and a side plate. Printed wiring boards 53 and 57;

Further, as shown in Fig. 13, the CRT 51 winds the metal band 58 (reinforcement band for preventing shrinkage) on the outer circumferential surface (end face of the display screen portion) at a predetermined time, and at four locations. (59) is excreted by means of spot welding or the like.

Next, the dismantling procedure of the cabinet of the general television receiver (hereinafter, abbreviated as television) will be described.

Fig. 9 is a flowchart of "cutting groove processing-> disassembly-> component removal" of a cabinet of a television. Fig. 10 shows a state in which the waste television is mounted on the conveyance pallet 2 and transferred to the home position, that is, step 2A.

Next, with the air cylinder 9, the conveyance pallet 2 placed on the plate 10 provided in the front end part of the air cylinder 9 is raised from the conveyance conveyor 1 (step 3A).

Thereafter, the cabinet 50 of the waste television is positioned in the X-axis and Y-axis directions (position determination / step 4A).

Positioning of the cabinet 50 in the Y-axis direction is Y-axis positioning means having two air cylinders 4 and 4 facing each other and plates 5 and 5 mounted to the front end of the cylinder 4 ( 6). As a matter of course, one of the two air cylinders moves forward to the correct position first, and then the other air cylinder moves forward.

Positioning in the X-axis direction is similarly performed by the X-axis direction positioning means 3. This positioning is performed at a predetermined timing by an air cylinder 7 which moves up and down in the Z axis direction, an air cylinder in the X axis direction (not shown), and a plate 8 attached to the tip of the cylinder 7. do.

Next, the dimensional law in the X-axis, Y-axis, and Z-axis directions of the position-determined cabinet is performed (step 5A / peripheral position measurement), and the measurement of the main surface position is performed in preparation for cutting groove processing in the next step 6A. For example, a laser beam sensor or an ultrasonic sensor is used. By operating the X-axis direction sensor 14, Y-axis direction sensor 15, and Z-axis direction sensor 16, each main surface position (bottom surface, ceiling surface, both sides) of the cabinet 50 is measured and recognized. Based on this position recognition data, a cutting tool 13 such as an end mill is driven in a predetermined manner.

In the groove processing of step 6A, each main surface of the cabinet 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 rotary drive means 12 for predetermined rotation of the cutting tool 13 can be implemented by using a general 3-axis to 5-axis control robot 11 (for example, a scalar robot or the like) arbitrarily.

The rotation speed of the end mill tool 13 is about several hundred RPM to about 25,000 RPM when the tool diameter is 3 mm to 20 mm.

Preferably, the rotational speed of the end mill tool having a diameter of 12 mm is about 8,000 RPM to 10,000 RPM.

In Fig. 12, a U-shaped cutting groove 60 is processed on the bottom surface (bottom plate) of the cabinet 50 by two rotary driving means 12 and a cutting tool (end mill) 13. . Further, a machining method using only one of the rotary drive means 12 and the cutting tool 13 is also possible.

The opened state is shown in FIG. 13 by folding the bottom of the cabinet. Next, the cycle of cutting groove processing to the cabinet is completed by sequentially performing step 7A (step of lowering the conveyance pallet) and step 8A (step of conveying the conveyance pallet to the next step).

In the next separate step (separate stage), the nut that has fastened the mounting member 59 is peeled off by a robot (not shown) or a human hand.

Subsequently, the CRT 51, the tuner 56, the antenna terminal plate 54, the chassis 52, the printed wiring board 53, the speaker device 55, and the like are separated by human hands or robot means (not shown). (All cities omitted). Thereafter, the process proceeds to the fractional reproduction processing step of step 9A.

In addition, although it is preferable to perform folding-opening operation of each main surface of the cabinet 50, and the separating operation of each structural member in a process separate from the process of a cutting groove, you may implement in the same process as a cutting process. .

In addition, in the flow of FIG. 9, replacement, addition, deletion, etc. of each step can be performed arbitrarily.

Moreover, the shape and the formation position of a cutting groove are not specifically limited, It goes without saying that you may implement to arbitrary shapes and a site | part.

For example, the ridge portion of the four corners in the Z-axis direction (the intersection of the ceiling surface and the side surface, or the intersection of the floor surface and the side surface), the X-axis direction and the Y-axis direction, and the predetermined surface so that the main surface does not fall down during processing. It is possible to form grooves while leaving the connecting part in place.

U-shaped cutting groove processing is possible not only on the bottom surface of the cabinet but also on the ceiling surface and both sides. The cabinet rotation means (not shown) may repeat the procedure of [rotate | turn-to-measure the position of a main surface → cutting] every 90 degrees.

14 shows an exploded state in which four main surfaces of the cabinet are opened. In addition, only the ridges of the four corners in the Z-axis direction of the cabinet may be cut, and each main surface may be pushed open by forcible force in a separate step.

According to the above embodiment, in the case of using a means for rotating the end mill tool at high speed as cutting groove processing, it can be treated dry without using water or the like.

The laser processing can be more easily performed three-dimensional processing, it is possible to correspond to the high speed of the curved surface processing. Water jet processing is applicable not only to cutting cabinets, but also to glass cutting of CRTs.

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

(d) "Step 6 to 71 CRT take out device-CRT transfer device"

In step 6, the operator loosens the tightening screw and removes the CRT from the cabinet. In addition, peripheral components (ground wire, element coil, etc.) are separated. In step 7, the cabinet, the dismantling parts, and the CRT are conveyed to the CRT processing step of the next step by the conveyance palette.

(e) "Step 8 / Electron Cutting"

In step 8, a diamond abrasive stone having an outer diameter of about 200 mm and a thickness dimension of 2 mm or less is rotated at a rotational speed of about 3,000 RPM to 5,000 RPM, and is advanced in a straight or gentle arc shape in one direction to advance the electron gun neck of the cathode ray tube. The addition is cut.

The cut electron gun is returned to the recycling step, and the CRT is returned to the next step.

(f) Step 9 / Metal Band Separators

In Step 9, the metal band for preventing shrinkage around the CRT is separated by high frequency heating.

Hereinafter, an embodiment of the metal band separating apparatus will be described with reference to FIGS. 15 to 23.

Fig. 15 is a conceptual configuration diagram of a dismantling process of the metal band for preventing deflation of a cathode ray tube in one embodiment of the present invention, and shows a main structural view of the dismantling device viewed from the side direction. Fig. 16 is a perspective view of the main portion of the metal band dismantling apparatus for preventing deflation in an embodiment of the present invention. FIG. 17 is a circuit diagram of an equivalent circuit of the high frequency heating means of FIG.

It is a principal side view of the cathode ray tube of an example used for description of this invention. Fig. 19 shows a flowchart (flow chart) of the dismantling process in one embodiment of the present invention.

The cathode ray tube 51 shown in FIG. 18 includes a panel portion, a funnel portion, a neck portion, an anti-expansion metal band 58 wrapped around the panel portion, and spot welding of the anti-expansion metal band. It is provided with the mounting member (tab) 59 attached to four corner parts. In addition, since the internal structure of the cathode ray tube is not a subject of the present invention, description thereof is omitted.

In FIG. 15 and FIG. 16, the conveyance pallet 2 is put on the conveyance conveyor 1 which is a conveyance means, and is conveyed by predetermined | prescribed fixed pitch.

The high frequency heating device (in particular, the high frequency induction heating device) 24 is provided at a predetermined position above the conveying conveyor 1.

The tab pressing means 21 has a function of pressing the mounting member (tab) 59 at the 4 kg to 6 kg at the time of heating the anti-deflating metal band 58.

In the high frequency heating device 24, an induction heating coil 25 for heating the anti-deflating metal band 58 to 350 degrees Celsius to 500 degrees Celsius is provided.

CRT lifting means 23 is provided for lifting the cathode ray tube CRT to a predetermined position in the induction heating coil 25 via an opening (through hole) formed in the center of the conveyance pallet 2. .

A CRT support means 22 having four pin members is planted and installed on the CRT mounting surface side of the conveyance pallet 2.

Next, the disassembly procedure of the metal band for preventing shrinkage of a general cathode ray tube will be described. A flowchart of one embodiment of the dismantling procedure is shown in FIG. 19.

In Fig. 15, the cathode ray tube 51 mounted by supporting the panel surface on the conveyance pallet 2 is first sent by a predetermined pitch and placed below the high frequency heating device (in particular, the high frequency induction heating device) 24. Located.

Thereafter, the cathode ray tube 51 is lifted up to a predetermined position in the induction heating coil 25 by the CRT lifting means 23. Subsequently, the tab pressing means 21 descends, and the de tab pressing end 21 presses the four member members (tabs) 59 at a pressure of 4 kg to 6 kg, respectively.

Next, the high frequency heating device 24 is operated, and the anti-deflating metal band 58 is heated to 350 degrees Celsius to 500 degrees Celsius. In this case, as the operating condition of the high frequency heating device, 180 V and 200 A were applied for 5 to 50 seconds at 1500 Hz to 2000 Hz. In addition, the application time of the high frequency heating apparatus is about 15 seconds in the case of a 20-inch CRT.

By this heating operation, the deflation preventing metal band 58 is rapidly heated up and expands. As a result, the metal band 58 is in a "shableable state" which is the state opposite to that at the time of shrink fitting. In addition, the shear adhesion of the resin impregnated in the non-combustible complete layer material (for example, acrylic resin, polyester resin, urethane resin, etc.) decreases due to the heat conduction from the anti-expansion metal band 58.

In the end, the adhesive force of the resin is lower than the pressing force, and the anti-expansion metal band 58 is peeled off from the panel portion.

In the center portion of Fig. 15, the falling metal band 58 for preventing shrinkage is indicated by a dashed line.

Thereafter, the cathode ray tube 51 from which the anti-deflating metal band 58 is separated is transferred by a predetermined pitch. In the next step, the anti-deflating metal band 58 is separated from the conveyance pallet 2.

Thereafter, the predetermined regeneration treatment is performed separately for the cathode ray tube glass and the regeneration treatment for the metal band for preventing shrinkage.

Two examples of the procedure of separating the deflating metal band 58 from the conveyance pallet 2 are shown in FIG.

The procedure shown in FIG. 19 is not specifically limited, For example, it is possible to implement a step as needed, such as adding, deleting, or changing.

17 shows an example of a circuit diagram and a schematic configuration specification of an equivalent circuit of the high frequency heating apparatus used in the above description.

The high frequency output of the high frequency heating apparatus used in this embodiment is a frequency of up to 60 Hz, and a range of 0.5 MHz to 2000 MHz. It goes without saying that the setting of the output and the frequency may be appropriately set corresponding to the inch size of the cathode ray tube to be handled. The lower limit output may also be about 2 ms.

As the CRT lifting means 23, any means such as an air cylinder or a robot can be used.

It does not specifically limit about the conveyance means of a conveyance pallet, For example, a roller conveyor, a belt conveyor, a chain conveyor, the pusher system using a fluid cylinder, etc. can be used.

The tab pressing means 21 is also not particularly limited, and for example, an air cylinder, a compression coil spring, or the like can be used.

Also, the pressure load can be used in a range of 4 kg or more per piece, up to 1000 kg in which the cathode ray tube is not destroyed, preferably about 4 to 40 kg.

In addition, the tip shape of the tab pressing means 21 is not particularly limited, and any shape can be used.

The tab pressing means shown in FIG. 16 shows an example using four independent pressing pins corresponding to each tab 59.

The tab pressing means 21A shown in FIG. 23 shows an example using a pair of T-shaped plates.

As shown in Fig. 23, the tab pressing means 21A of the T-shaped plate divides both sides corresponding to the tab to a predetermined width.

Next, the operation of a pair of T-shaped plates will be described with reference to FIG.

First, the tab pressing means 21A of the pair of T-shaped plates sandwiches the side surface of the metal band 58 of the CRT 51 and positions the CRT 51 at a predetermined position in the horizontal direction. Thereafter, the clamping force is released (the insertion position of the T-shaped plate is left or slightly retracted), and the T-shaped plate 21A is lowered in the vertical direction, and the tab 59 is pressed.

The T-shaped plate 21A presses two tabs 59 on one sheet (one side). Next, another conveyance pallet in the Example of this invention is demonstrated.

FIG. 20 (A) is a plan view of another conveyance pallet used for the metal band disassembly apparatus for preventing the deflation of the cathode ray tube of the present invention, and FIG. 20 (B) is a cross-sectional view of FIG. 20 (A) taken from S1 to S1. .

Fig. 21 (A) is a plan view of another conveyance pallet of the present invention, and Fig. 21 (B) shows a cross-sectional view of Fig. 21A taken at S2 to S2.

The conveyance pallet 2A of FIG. 20 (A) and the conveyance pallet 2B of FIG. 21 (A) are plate-shaped bodies which are made of wood, metal members, such as AL, or resin members, such as ABS and Duracon.

The outer shape of the conveyance pallet is roughly rectangular.

Moreover, the conveyance pallet of a plate-shaped body forms predetermined recessed parts in four surroundings, and has through-hole 27A, 27B in a center part, respectively.

In addition, 2 A of conveyance pallets which are shown to FIG. 20 (A) form the larger annular recessed part 29 in step shape at the edge part of the upper edge part of the said through hole 27A. A ring-shaped elastic member 26 is fitted in the annular recessed portion 29. The ring-shaped elastic member 26 is either a rubber member or a plastic member having a hardness of about 35 ° to 50 ° or a combination structure thereof.

Although it does not specifically limit as a rubber member, For example, arbitrary members, such as a silicone rubber, a fluorine rubber, a butyl rubber, urethane rubber, a natural rubber, can be used. Of course, a rubber member foamed into a sponge shape can also be used.

Although it does not specifically limit as a plastic member, For example, arbitrary plastic members, such as a silicone type, vinyl chloride type, a nylon type, a styrol type, can be used.

The cathode ray tube CRT to be dismantled is mounted on the center of the conveyance pallet 2A, 2B with the tube face down (FIG. 20CB), and the cathode ray tube is indicated by a dashed-dotted line in FIG. 21B.

Therefore, the ring-shaped elastic member 26 elastically deforms due to its own weight of the cathode ray tube 51, and is almost in close contact with the tube surface of the cathode ray tube 51.

As a result, the cathode ray tube 51 is not displaced by the frictional force of the cathode ray tube 51 and the elastic member 28 during conveyance and stop of the conveyance pallet 2A, and the initial mounting position state can be maintained. have.

In the conveyance pallet 2B shown in FIG. 21, instead of the ring-shaped elastic member, three elastic member intermediaries 28 at the upper peripheral edge portion of the through hole 27B are arranged at roughly equally divided angles. .

As a constituent member of the elastic member piece 28, the same material as in the case of Fig. 20 can be used.

In FIG. 21, 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 conveyance pallet 2B is conveyed and stopped, the cathode ray tube 51 is not displaced by the frictional force of the cathode ray tube 51 and the piece of elastic member 28, and the initial mounting position is maintained. Can be.

In addition, the external shape of the conveyance pallet 2A (2B) is not specifically limited, Arbitrary forms can be used. Also, the shape of the through holes 27A and 27B is not limited to a circle, and arbitrary shapes such as rectangles can be used.

According to the above embodiment, separation of the metal band for preventing deflation can be performed efficiently in a short time.

In addition, large-scale equipment is unnecessary.

Moreover, the position shift of the cathode ray tube mounted on the conveyance pallet can be prevented.

(g) "Step 10 / CRT dual panel measuring device"

Step 10 determines the presence or absence of the safety glass adhere | attached on the panel surface of a CRT, and selects the CRT which adhered to the safety glass, and returns it to a separate process.

Hereinafter, an embodiment of a CRT dual panel measuring device (CRT discriminating device) will be described with reference to FIGS. 24 to 26.

24 is a sectional view showing the main concept of a process of measuring the external appearance of the cathode ray tube in one embodiment of the present invention. 25 is a cross-sectional view of the main part of the concept of the measurement process from the distance sensor to the fluorescent surface of the cathode ray tube according to the embodiment of the present invention. Fig. 26 shows a flow chart (flow chart) of the measuring step to the separating step of the cathode ray tube in one embodiment of the present invention.

As shown in Fig. 24, the cathode ray tube 51 from which the metal band is separated has a video display surface at a predetermined position of the conveyance pallet 2 having the through hole 91 and the data carrier 92 at the center thereof. Pipe face down).

In addition, the conveyance pallet 2 may be the same as the conveyance pallet demonstrated by the said FIG. 20, FIG. 21, and may be another kind of a separate line.

In this state, at least one of the vertical dimension and the horizontal dimension c of the panel portion of the cathode ray tube 51 is measured by the distance sensor 93. This measurement determines the image display surface size (surface size) of the cathode ray tube. Then, the measured values and the judgment data are stored by the general memory means (not shown). The length dimension c of the cathode ray tube 51 is measured from the length a between the opposing distance sensors 93 and the lengths b1 and b2 from the distance sensor 93 to the panel portion of the cathode ray tube 51. .

Next, as shown in FIG. 25, the crab unit 95 provided with the distance sensor 94 abuts on the image display surface. Thereafter, the distances h1 and h2 from the distance sensor 94 to the fluorescent surface of the cathode ray tube 51 are measured.

In Fig. 25, the left side is a general cathode ray tube 51, and the safety glass is not provided on the image display surface. The right side shows the special specification cathode ray tube 51A provided with the safety glass 80 via the adhesive material 81 (for example, unsaturated polyester resin).

The plate thickness of the safety glass 80 is about 2 mm to about 3 mm, the plate thickness of the panel image display unit is about 10 mm, the thickness of the adhesive member 81 is about 2 mm, and the distance from the image display surface. The distance from the 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 80. This can roughen the measurement precision of the distance sensor 94, and can use a cheap measurement apparatus.

In addition, as the distance sensor 94, arbitrary sensors, such as a laser beam or an ultrasonic wave, can be used.

The process from measurement of the cathode ray tube to separation will be described in detail with reference to FIG. 26.

In step IC, the external dimension of the cathode ray tube is measured. That is, the distance a of the opposing pair of laser type distance sensors 93 is set to predetermined. Next, the distances b1 and b2 from the laser type distance sensor 93 to the cathode ray tube 51 are measured, and the external dimension c of the cathode ray tube is obtained from "c = a- (b1 + b2)".

In step 2C, the distance measurement (measurement) and tube type between the distance sensor fluorescent surfaces are determined.

That is, the measurement unit 95 abuts on the image display surface of the cathode ray tubes 51 and 51A. Next, the distances h1 and h2 to the fluorescent surface coated on the panel inner surface side of the cathode ray tubes 51 and 51A are measured by the laser type distance sensor 94.

Next, the measured values of h1 and h2 are previously input to the computer. The distance "H" between the distance sensor and the fluorescent surface is compared.

In the case of the cathode ray tube 51 which is not provided with the safety glass 80, "H value" is prescribed | regulated according to each inch size. Therefore, the "H value" is automatically set based on the external dimension information of the step IC.

When "H" is almost equivalent to "h1", it is determined that the cathode ray tube placed on the conveyance pallet 2 is a general cathode ray tube (without safety glass) 51.

When "H" is smaller than "h2" and the difference between "H" and "h2" is about 3 mm-about 4 mm or more, it is determined that the cathode ray tube is the cathode ray tube 51A with safety glass.
