DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel carrying device, a panel processing releasing device and a panel processing releasing system. More specifically, the present invention relates to a panel transfer device for transferring a color cathode ray tube panel in a step of forming a fluorescent film or a black matrix film on the inner surface of the color cathode ray tube panel, for example.

[0002]

2. Description of the Related Art In the process of manufacturing a color cathode ray tube, there is a step of forming a black matrix film or a fluorescent film on the inner surface of a color cathode ray tube panel (a glass panel forming the front portion of the color cathode ray tube). In the panel processing step for this purpose, various processing steps such as injecting a coating liquid such as a black matrix film or a fluorescent film, spin coating, cleaning, and drying are necessary. A panel transfer device is required for holding and sequentially transferring to the next processing step. Also,
In each processing step, the panel needs to be held at a tilt angle determined by the type of processing and the structure of the processing apparatus. For example, when applying a coating liquid for a fluorescent film to a panel, it is necessary to hold the inner surface of the panel facing upward, inject the coating liquid into the panel, and rotate the panel. For this reason, the panel transfer device requires a tilt mechanism for tilting the panel to a predetermined tilt angle in each step and a guide mechanism for the tilt mechanism.

An example of such a panel transfer device is disclosed in Japanese Patent Application Laid-Open No. 53-36174. Although not shown, in this panel transfer device,
A plurality of carriers are radially attached to an outer peripheral portion of a turntable that rotates in a horizontal plane, and a panel holding portion is attached to a tip end portion of each carrier so as to be vertically rotatable. The panel holder is tilted up and down by a tilt mechanism, and the tilt angle controller is engaged with a guide groove provided on the outer peripheral wall surface of the base that supports the turntable. Then, when the rotary table rotates and the carrier moves, the tilt angle control unit moves up and down by moving the guide groove, and the tilt mechanism is driven accordingly, and the panel holding unit moves to a predetermined position at each position. The tilt angle is maintained.

Explaining the operation in the panel processing step, the panel holding portion faces downward at the loading position and holds the panel in that posture. The panel held by the panel holding unit is kept at a predetermined tilt angle in each processing step by intermittently rotating the rotary table, and is sequentially subjected to necessary processing. In this way, the panel is sequentially and continuously processed while moving around the rotary table to form the black matrix film and the fluorescent film. The panel holding part that holds the panel that has completed all processing moves to the unloading position with the posture facing downward, releases the processed panel at the unloading position, and the processed panel performs the panel processing. Delivered from the process. The panel holding part, which has released the processed panel, moves to the loading position, holds the unprocessed panel again, and passes through each panel processing step.

[0005]

However, in such a panel transfer device, even if the panel holding portion holding all the processed panels returns to the unloading position, the processed panels remain. If the panel remains in the unloading position and the controller does not output the unloading command, the panel holding unit cannot unload the processed panel, and the panel can be moved to the loading position while holding it. is there. Further, even if the unloading command is output at the unloading position, the panel may move to the loading position without being disengaged from the panel holding unit due to a trouble of the panel holding unit.

When such a trouble occurs, the rotary table is stopped to wait until the panel is unloaded at the unloading position, or the rotary table is stopped to manually remove the panel from the panel holding portion. If it is removed, the processing time of the other panel being processed changes, so that the quality of the other panel deteriorates or a defective product occurs.

For this reason, in the past, when the panel holding portion holding the processed panel could not be unloaded at the unloading position, it was passed through the unloading position as it was. In this case, the panel is held by the panel holding portion again at a predetermined tilt angle in each processing step, and the processing such as heating is performed again, so that the panel becomes a defective product. .

Further, when the processed panel is reprocessed,
Not only does the panel become defective, but the panel that is still in a high temperature state immediately after processing is heated again. Therefore, parts used in panel holding parts, especially rubber-based parts (such as clamp heads and suction parts). In the case of the panel holding portion having the head, the clamp rubber, the suction pad, etc.) may be overheated and deteriorated, and the life of the parts may be shortened.

The present invention has been made in view of the above-mentioned drawbacks of the conventional examples, and an object thereof is to re-treat the panel in the panel treatment step when the treated panel cannot be unloaded. This is to prevent defective products from being generated and deterioration of components and the like of the panel holding portion.

[0010]

A panel carrying device of the present invention moves along a closed moving path, and a panel holding portion for holding the panel, a tilt mechanism portion for tilting the panel held by the panel holding portion. The tilt angle control section includes a tilt angle control section that displaces in a direction intersecting the moving direction of the panel holding section that operates the tilt mechanism section, and a guide rail that movably engages the tilt angle control section. Is the guide
At least the tilt angle control unit to move along the rail.
Part of it is also inserted into the grooved guide rail, and the tilt angle control unit is displaced by the guide rail as the panel holding unit moves, and the tilt mechanism unit controls the tilt angle of the panel. In the panel transfer device, the tilt angle
Insert the insertion part of the control part into the guide rail to the outside of the guide rail.
By moving the tilt angle control unit,
The feature is that it can be released from .

Here, the tilt angle control unit is set to a guide rail.
When it is released from the
It is preferable that the panel faces directly below.

As the structure of the tilt angle control section, the tilt mechanism section is provided with a rotatable rotating body, the engaging section provided on the rotating body is inserted into the guide rail, and the rotating body is rotated. Therefore, the engaging portion may be moved to the outside of the guide rail and released. Alternatively, the tilt angle control unit is provided with a movable body that can move in a direction orthogonal to the displacement direction of the tilt angle control unit, and the engaging portion provided on the movable body is inserted into the guide rail to move the movable body. By doing so, the engaging portion may be moved to the outside of the guide rail and released.

[0013]

The panel processing releasing apparatus of the present invention comprises a tilt angle control section of the panel transporting apparatus, a switching operation section that can be connected and disconnected, and a drive mechanism for driving the switching operation section.
The tilt angle control section is released from the guide rail by driving the switching operation section connected to the tilt angle control section, or the tilt angle control section is engaged with the guide rail.

The panel processing release system of the present invention is a panel processing release system for releasing the tilt angle control section of the panel transfer device from the guide rail by the panel processing release device, and holds the panel at the panel unloading position. It is determined whether or not a panel unloading command is output to the panel, and if the panel unloading command is not output, the tilt angle control unit related to the panel holding unit is released from the guide rail. It has a feature.

Another panel processing release system of the present invention is
A panel processing canceling system for canceling a tilt angle control section of the panel transporting apparatus from a guide rail by the panel processing canceling apparatus, comprising a means for detecting whether or not a panel holding section holds the panel. When the panel holding unit holds the panel after the unloading timing, the tilt angle control unit related to the panel holding unit is released from the guide rail.

[0017]

The panel transfer apparatus of the present invention is provided with a tilt angle control unit.
Move the insertion part into the guide rail to the outside of the guide rail.
By doing so, it has a function of releasing the tilt angle control section from the guide rail section. For example, if the engaging part provided on the rotating body of the tilt angle control part is inserted into the guide rail having a groove shape, the tilt angle control part is displaced by the engaging part moving along the guide rail. The panel is tilted accordingly, but when the rotating body is rotated to move the engaging portion to the outside of the guide rail, the tilt angle control portion is released and the panel is not tilted. Alternatively, if the tilt angle control unit is provided with a movable body that can move in a direction orthogonal to the displacement direction, and the engaging portion provided on the movable body is inserted into the guide rail, the tilt angle control unit will be Is displaced by moving along the guide rail, and the panel tilts accordingly.However, when the moving body is moved to move the engaging portion outside the guide rail, the tilt angle control section is released and the panel is tilted. Will not be tilted.

Therefore, when the panel holding unit cannot unload the panel at the unloading position, the ununloaded panel is conveyed to the panel processing step again while being held by the panel holding unit. However, when the tilt mechanism is released, the panel is not brought into a position or posture in which it can be processed, and is conveyed, for example, in a state in which it is directed downward so as not to be processed. For this reason, the processed panel is not processed again in the panel processing step, and when it reaches the unloading position again, it is unloaded from the panel holding portion and sent out as a product. As a result, it is possible to prevent the panel from being a defective product, and it is possible to prevent deterioration of the components of the panel holding portion.

Further, if the panel held by the panel holding section in which the tilt angle control section is released is directed downward, it is possible to pass the panel processing step with the processed surface of the panel facing downward. It is possible to prevent the treated surface of the panel from being contaminated.

Further, in the panel processing releasing apparatus of the present invention, the switching operation section is connected to the tilt angle control section of the panel carrying device, and the driving mechanism drives the switching operation section to guide the tilt angle control section. It can be released from the rail. On the contrary, the tilt operation control unit can be engaged with the guide rail by driving the switching operation unit. Therefore,
According to this panel processing release device, the release and re-engagement of the tilt angle control unit with the guide rails can be mechanized without manual work, and work safety and labor saving can be achieved. Further, when it is not necessary to switch the tilt angle control unit, the switching operation unit can be separated from the tilt mechanism unit.

Further, in the panel processing release system of the present invention, since it is judged at the panel unloading position whether or not the panel unloading command is output to the panel holding portion, the panel unloading command is not output. When the panel cannot be unloaded due to the damage, the tilt angle control section can be automatically released from the guide rail.

Further, another panel processing releasing system of the present invention is provided with means for detecting whether or not the panel holding portion holds the panel, so that when the panel is not unloaded from the panel holding portion. Can detect this and automatically release the tilt angle control unit from the guide rail.

Then, when the drive shaft 26 is slid in the length direction of the arm 21a, the pinion gear 25 rotates due to the engagement with the rack gear 30, and in conjunction with this, the panel holding portion 41 tilts around the shaft 23. A ring-shaped stopper 29 is attached to the drive shaft 26, and the thrust range of the drive shaft 26 is regulated by bringing the stopper 29 into contact with the thrust bearings 27 and 28. The tilting range, that is, the tilt angle θ is limited to a range of 0 ° to 167 °, for example (the tilt angle θ is 0 ° when the panel holding portion 41 faces downward as shown in FIG. 2). Particularly, when the stopper 29 is in contact with the thrust bearing 27, the panel holding portion 41 is positioned so as to face downward.

As shown in FIG. 2, the panel holding portion 41 is such that a clamp head 46 is rotatably supported at the tip of a main body portion 44 having a bracket 43.

The panel processing canceling device 91 is installed at a fixed position where the tilt angle control section 61 is canceled or returned. It is preferably installed in the unloading position or the loading position, but may be installed between the unloading position and the loading position, or in a section until the first panel processing position is reached. Moreover, as shown in FIG. 8, the panel processing canceling device 91 is installed by axially aligning the push pin 113 and the lock pin 68 of the tilt angle control unit 61. Further, the rail plate 51 is not necessarily required in the section where the tilt angle θ of the panel holding portion 41 between the unloading position and the loading position is maintained at 0 degree, and even if the rail plate 51 is missing in this section. It doesn't matter. However, since there is a risk that the panel holding portion 41 will sway inadvertently due to vibration or the like, the tilt angle control portion 61 is prevented from moving by bringing the guide rail 52 of the rail plate 51 into contact with only one side of the traveling roller portion 84. , The tilt angle θ is held at 0 degree.

However, when the panel processing canceling device 91 switches the tilt angle control section 61 to the canceling state, it is carried out as follows. When the panel holding unit 41 that could not unload the panel B moves to the position of the panel processing release device 91 and the tilt angle control unit 61 faces the release device body 95, the actuator 100 causes the release device body 95 to follow the rail 94. Then, the push pin 113 of the switching jig 112 is inserted into the through hole 76a of the rotation block 73 as shown in FIG. Push pin 11
When 3 is inserted into the through hole 76a, the head 70 is pushed by the push pin 113 and the lock pin 68 comes out of the through hole 76a of the rotary block 73, as shown in FIG. On the other hand, the insertion depth of the push pin 113 into the through hole 76a is regulated by the end surface of the large diameter portion 114 contacting the rotating block 73, so the fixed block 6
2 does not reach the lock pin storage hole 64. Therefore, in this state, the rotation block 73 is unlocked, and when the actuator 103 is driven to rotate the switching jig 112 as shown in FIGS. 9A and 9B, the rotation block 73 rotates. When the rotation block 73 rotates, FIG.
As described above, the traveling roller portion 84 comes off the guide rail 52, and the tilt angle control portion 61 is released from the guide rail 52. When the rotation block 73 rotates and the end of the cam groove 82 reaches the position of the cam pin 72, the rotation of the rotation block 73 stops. When the rotation block 73 stops rotating, the lock pin 68 coincides with the other through hole 76b, so that the lock pin 68 projects into the through hole 76b and the rotation block 73 is locked again. Then, the release device main body 95 is retracted to the original position, and the switching jig 112 is separated from the tilt angle control section 61. When the tilt angle control section 61 is released from the guide rail 52 in this way, the tilt mechanism section 22 does not work, so that the panel holding section 41 is lowered downward by its own weight and the stopper 29 is held in contact with the thrust bearing 27. The state in which the portion 41 is positioned and the panel B is directed downward (tilt angle θ = 0 degree)
Is held.

On the contrary, when the tilt angle control section 61 is returned, the operation is as follows. When the panel holding unit 41 that has unloaded the panel B moves to the position of the panel processing release device 91 and the tilt angle control unit 61 faces the release device body 95, the release device body 95 is advanced by the actuator 100 along the rail 94. The push pin 113 of the switching jig 112 is moved to the through hole 76b of the rotation block 73.
Is inserted into. When the push pin 113 is inserted into the through hole 76b, the lock pin 68 is retracted and unlocked. Therefore, the actuator 103 is driven and the switching jig 112 is rotated to the side opposite to the release state. When the rotation block 73 is rotated by the switching jig 112, the rotation block 73 shown in FIG.
As shown in (a), the traveling roller portion 84 returns into the guide rail 52, and the tilt angle control portion 61 engages with the guide rail 52. When the rotary block 73 rotates and the other end of the cam groove 82 reaches the position of the cam pin 72, the rotation of the rotary block 73 stops. When the rotation block 73 stops rotating, the lock pin 68 is aligned with the other through hole 76a, so that the lock pin 68 projects into the through hole 76a and the rotation block 73 is locked again. Then, the release device main body 95 retreats to the initial position again.

As described above, the panel processing canceling device 91
By using, the rotation block 73 can be unlocked, the rotation block 73 can be rotated, and the traveling roller portion 84 can be separated from the guide rail 52 or returned to the guide rail 52 and engaged. The tilt angle control unit 61 can be mechanically switched between release and return without manual work.

Further, according to the panel processing canceling system of the present invention described below, the panel holding portion 41 has the panel B.
That the tilt angle control section 61 of the panel holding section 41 is set to the guide rail 5
Panel B that was automatically released from 2 and could not be unloaded
When the panel holding unit 41 holding the unloading of the panel B unloads the panel B, the tilt angle control unit 61 of the panel holding unit 41 can be automatically engaged with the guide rail 52. .

FIG. 11 is a block diagram showing the configuration of the panel processing cancellation system. Reference numeral 121 is a controller with a built-in microcomputer. Reference numeral 122 denotes a panel sensor for detecting whether or not the panel B is held on the clamp head 46, and outputs the detection signal to the controller 121. Panel sensor 122
Is composed of, for example, an optical detector provided at the unloading position or the loading position, but may be detected from electrical tracking data. Also, 12
Reference numeral 3 denotes a traveling roller portion state determining means for detecting whether the traveling roller portion 84 is engaged with the guide rail 52 or disengaged from the guide rail 52. The determination result by 123 is also output to the controller 121. The running roller portion state determining means 123 is, for example, as shown in FIG. 8, a light projecting portion 115 such as a photoelectric tube, a light emitting diode, or a semiconductor laser arranged near the panel processing canceling device 91, and a light receiving portion such as a photodiode or phototransistor. Consists of 116,
The traveling roller portion 84 of the panel holding portion 41, which is stationary at a position facing the releasing device body 95, is lowered and locked at a position where it engages with the guide rail 52, or at a position where it is pulled out of the guide rail 52. You can determine if it is locked. That is, when the light beam emitted from the light projecting unit 115 is blocked by the traveling roller unit 84 and is not detected by the light receiving unit 116, it is determined that the traveling roller unit 84 can be engaged with the guide rail 52. . The controller 121 determines whether or not the unloading position is in a state where the panel B can be received, and if possible, outputs a panel unloading command to the panel holding unit 41 in the unloading position. On the other hand, when the panel B is in the unloading position and the panel cannot be received, the panel unloading command is not output, and the panel holding unit 41 holds the panel B while the loading position is maintained. Move to. The controller 121 also outputs a panel loading command to the panel holding unit 41 at the loading position. Further, the panel processing canceling device 91
The actuators 100, 103 of the controller 12
When the control signal is output from 1 and the panel is not unloaded, the panel processing release device 91 is driven to release the tilt angle control section 61 of the panel holding section 41 from the guide rail 52, or the guide rail 52. The tilt angle control unit 61 that has been released from is engaged as before.

In FIG. 12, the panel processing release system automatically releases the tilt angle control section 61 from the guide rail 52 so that the tilt mechanism section 22 does not operate, or the tilt angle control section 61 is returned to the guide rail 52. 6 is a flowchart showing a procedure for enabling the tilt mechanism unit 22 to operate. In this flowchart, the panel processing canceling device 91 is installed at the unloading position. When the panel holding unit 41 holding the processed panel B that has undergone the panel processing step reaches the panel unloading position (S131, S132), the controller 121 determines whether the panel unloading position is in a state in which the panel B can be received. If it can be accepted, the panel unloading command is output to the panel holding unit 41, and if it is unacceptable, the panel unloading command is not output (S133). When the panel unloading command is output, the panel holding unit 41 unloads the panel B at the panel unloading position (S134). Next, it is determined whether or not the panel B can be unloaded from the panel holding portion 41 based on the signal from the panel sensor 122 (S135). When it is confirmed that the panel B has been unloaded, the traveling rail portion state determination means 123 determines whether or not the traveling rail portion 84 is lowered so that the tilt mechanism portion 22 can operate (S136), and the tilt mechanism. If the part 22 is operable, the panel holding part 4
1 is moved to the loading position, and when the panel holding unit 41 reaches the loading position (S138, S139), the controller 121 outputs a panel loading command to the panel holding unit 41 to load the panel B (S140).

On the other hand, when the panel unloading command is not output at the panel unloading position (S133),
The traveling roller portion state determination means 123 determines whether or not the traveling rail portion 84 is lowered so that the tilt mechanism portion 22 can operate (S141). If the tilt mechanism portion 22 is in the operable state, , The panel processing releasing device 91 is driven to move the traveling roller portion 84 to the guide rail 5.
2 to release the tilt mechanism section 22 (S14
2). Similarly, when the panel B is not unloaded from the panel holding portion 41 (S133, S134, S135) in spite of the panel unloading command being output (S133, S134, S135), the traveling roller portion state determination unit 123 causes the traveling rail. It is determined whether or not the portion 84 is descending (S141), and when the tilt mechanism portion 22 is in an operable state, the panel processing releasing device 91 is driven to move the traveling roller portion 84 from the guide rail 52. The removal tilt mechanism section 22 is released (S1
42).

Further, when the panel B cannot be unloaded and the panel holding unit 41 which has undergone the panel processing step again reaches the panel unloading position, the panel holding unit 41 unloads the panel B in the panel unloading position (S131). ~ S135). In the panel holding unit 41 that has unloaded the panel B, the traveling roller unit state determination unit 123 determines whether the traveling rail unit 84 is lowered so that the tilt mechanism unit 22 can operate (S136), and the tilt mechanism unit 22 is determined. Is not in an operable state, the panel processing canceling device 91 is driven to return the traveling roller portion 84 into the guide rail 52 to restore the tilt mechanism portion 22 (S137). Then, when the panel holding unit 41 reaches the panel loading position, a panel loading command is output and the panel B is loaded on the panel holding unit 41 (S138 to S140).

Although the panel processing canceling device 91 is provided at the unloading position in the above flowchart, it is easy to change the flowchart according to the installation position of the panel processing canceling device 91. Further, in the above flow chart, the tilt mechanism unit 22 is released when the panel unloading command is not output and when the panel sensor 122 detects that the panel B is not unloading. There is no problem even if only one of them is judged and the tilt mechanism section 22 is released.

In the tilt angle control section 61 shown in FIGS. 4 to 6, the traveling roller section 84 is rotated to be pulled out from the guide rail 52, but the tilt angle control section 61 linearly moves the traveling roller section 84. The guide rail 52 may be moved to and removed from the guide rail 52, or may be inserted into the guide rail 52. 13A and 13B are a plan view and a front view showing a tilt angle control unit 151 having another structure, in which a lock pin 68 and a cam groove 82 provided on the fixed block 62 and the movable block 73 are shown. Although the mechanism such as the above is almost the same as that of the tilt angle control unit 61 in FIGS. 4 to 6, the guide unit 152 formed in the fixed block 62 holds the lifting member (moving body) 153 slidably in the vertical direction. The traveling roller portion 84 is provided at the lower end portion of the elevating member 153. A pinion gear portion 154 is formed in a part of the rotation block 73, and the pinion gear portion 1
54 is a rack gear portion 155 provided on the elevating member 153.
And are engaged. Therefore, when the rotation block 73 is rotated by the panel processing releasing device 91, the elevating member 153 slides up and down due to the meshing of the pinion gear portion 154 and the rack gear portion 155. Therefore, when the rotating block 73 is rotated to raise the elevating member 153,
The traveling roller portion 84 comes out of the guide rail 52, and the tilt angle control portion 61 is released. Further, when the rotating block 73 is rotated to lower the elevating member 153, the traveling roller portion 84 is inserted into the guide rail 52 and the tilt angle control portion 61 becomes operable.

Further, the guide rail 52 is not limited to the concave groove shape, but as shown in FIG.
May be used. In this case, the guide rail 52 may be sandwiched between the pair of traveling roller portions 84 provided on the rotation block 73.

The guide rail is not limited to one provided on a horizontal rail plate. For example, JP-A-53-36174
The configuration of the present invention can be easily applied to a structure in which the tilt angle control unit is moved by a guide rail provided on a vertical wall surface as disclosed in Japanese Patent Laid-Open Publication No. 2003-242242.
