Funnel) and tubular neck fused to the vertices of the channel. Panels, channels and necks are all made of glass, in particular panels and channels are produced by press molding a molten glass mass called a gob to the desired size and shape.
    [17] The panel, on the other hand, has a face that displays an image and a skirt having a seal edge that extends backward from the edge of the face and the channel is joined to the panel. In general, it has a rough surface, so the surface of the panel should be properly polished to remove optical defects. Usually the surface polishing of the panel is done by a panel polishing machine.
    [18] The panel polishing apparatus has a table capable of rotational movement and a polishing tool capable of moving forward and backward while being disposed on an upper portion of the table, and the panel polishing apparatus is mounted on the table to be fixed, and then the upper polishing tool is placed on the outer surface of the panel. The panel was polished by contact. At this time, the polishing tool on the table and the upper part rotates and rotates the front and rear motions at the same time, and polishes the panel by relative movement.
    [19] However, such a conventional polishing apparatus has a disadvantage in that the inner surface of the panel cannot be processed as it is configured to polish only the outer surface of the panel.
    [20] That is, many scratches are generated on the outer surface and the inner surface of the panel during molding of the panel. Such scratches may cause optical defects, so it is preferable to remove them. However, the conventional polishing apparatus is configured to polish only the outer surface of the panel, that is, the face and the seal edge of the panel as described above, so that the inner surface of the panel cannot be processed.
    [21] Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a panel polishing apparatus for a cathode ray tube that can be polished as well as the outer surface of the panel.

Free movement of the left, right, left and right movements.
    [27] On the other hand, such a table 40 is configured by the rotary shaft 10 so as to be able to move forward and backward, left and right. That is, the receiving groove 44 is formed on the bottom of the table 40, the eccentric cam 14 of the rotary shaft 10 is fitted through the bearing 46 in the receiving groove 44. The table 40 supported by the eccentric cam 14 is to be moved back and forth and left and right along the eccentric cam 14 as the rotary shaft 10 is rotated. Here, the table 40 is a center of the eccentric cam 14 is eccentric 24mm away from the center of the axis of rotation 10 as the width of the front and rear left and right movement of 48mm.
    [28] And the upper surface of the table 40 is provided with an inner surface polishing tool 50 for polishing the inner surface of the panel (P). The inner surface grinding tool 50 is comprised from the support part 52 fixedly supported by the upper surface of the table 40, and the grinding | polishing part 54 which protrudes upwards from the support part 52. As shown in FIG. In particular, the polishing unit 54 is formed to be similar to the curvature of the inner surface of the panel (P) and at the same time configured to be elastically deformed so as to be in close contact with the inner surface of the panel (P). Here, the polishing portion 54 of the inner surface polishing tool 50 is composed of a rubber material to enable elastic deformation. The inner surface polishing tool 50 is brought into contact with the inner surface of the panel P while the table 40 moves forward, backward, left and right at the same time.
    [29] On the other hand, since the inner surface polishing tool 50 has little polishing capability in itself, it is necessary to supply a separate abrasive, in particular, an abrasive fluid called a slurry in which water and abrasive are mixed. This is installed. As shown in FIG. 1, the polishing fluid supply means includes a storage tank 60 capable of storing the polishing fluid, a fluid pump 62 for discharging the polishing fluid of the storage tank 60 at a predetermined pressure, and a fluid pump 62. The transfer pipe 64 for feeding the abrasive fluid discharged from the < RTI ID = 0.0 >) < / RTI > and the pressurized abrasive fluid is formed in the table 40 and the inner abrasive tool 50 to guide the contact portion between the inner abrasive tool 50 and the panel P. It consists of a passage 66. The polishing fluid supply means enables the polishing of the inner surface of the panel P by supplying the polishing fluid to the contact portion between the inner polishing tool 50 and the panel P. FIG.
    [30] In addition, the present invention is a panel polishing apparatus is provided with a panel movement means for moving the panel (P) from side to side to increase the polishing efficiency of the panel (P). The panel movement means includes a first cylinder 70 and a second cylinder 72 disposed on both left and right sides of the table 40, and cylinder rods of the first and second cylinders 70 and 72 as shown in the drawing. It is attached to each end of 70a, 72a, and consists of the push board 74 which supports both sides of the panel P. As shown in FIG. Here, the first cylinder 70 is a pneumatic cylinder, is extended by the supplied pneumatic pressure to press the panel (P) one side. The second cylinder 72 has an elastic spring 72b therein, and elastically supports the other side of the panel P. As shown in FIG. In particular, the second cylinder 72 elastically supports the panel P, which is moved by the first cylinder 70, as shown in FIG. It serves to return. As a result, the panel movement means of such a configuration is to increase the polishing efficiency by the relative movement of the panel (P) and the inner surface grinding tool (50).
    [31] On the other hand, the upper portion of the table 40 is provided with an upper abrasive tool 80 to polish the upper surface of the panel (P), the upper abrasive tool 80 is moved back and forth by the movable shaft 82, which can move back and forth While polishing the upper surface of the panel (P). At this time, the upper polishing tool 80 is in close contact with the outer surface of the panel (P) by a pressing means, for example, a pneumatic cylinder (not shown) installed on the upper to polish the outer surface of the panel (P). Here, since the upper polishing tool 80 and the operating shaft and the pressing means are already known, a detailed description thereof will be omitted.
    [32] Next, look at the operation of the present invention having such a configuration as follows. First, the panel P is placed on the upper surface of the table 40 so that the face faces upward. At this time, it is a matter of course that the inner surface grinding tool 50 is disposed inside the panel (P). Then, when the device is operated, the driving motor 20 is driven, and as the driving motor 20 is driven, the rotating shaft 10 starts to rotate, and as the rotating shaft 10 rotates, the table 40 is also eccentric. As it rotates along the cam 14, it starts to move forward, backward, left and right. In this state, the inner polishing tool 50 starts to contact the inner circumference of the panel P. At this time, the grinding fluid is supplied by the grinding fluid supply means, and thus the inner surface of the panel P is polished. To be processed.
    [33] Meanwhile, as the device is turned on, the panel movement means, that is, the first and second cylinders 70 and 72, are also operated. Therefore, the panel P is relatively moved from side to side with respect to the inner grinding tool 50. It will increase the polishing efficiency even more. At the same time, the upper polishing tool 80 of the upper part also polishes the outer surface of the panel P while moving back and forth.
    [34] As described above, the panel polishing apparatus of the present invention is configured to enable the table 40 to be moved forward, backward, left and right with respect to the panel P, and the inner surface polishing tool which can contact the inner surface of the panel P on the table 40. (50), and by providing the polishing fluid supply means for supplying the polishing fluid to the contact portion of the inner surface polishing tool 50 and the panel (P), has the advantage that the inner surface of the panel (P) can be polished. . In particular, by providing the panel movement means to the relative movement of the panel (P) relative to the inner surface grinding tool 50, there is an effect that can more efficiently process the inner surface polishing of the panel (P). On the other hand, in the drawings of the present invention, although shown to process a panel P having a flat face, it is a matter of course that a panel having a face, such as a curved surface, an aspherical surface.
    [35] Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.
