[Technical field to which the invention belongs] The present invention relates to a surface of a polishing device, and more particularly to a glass plate continuously loaded by a continuous polishing device. [Prior art] Generally known glass plates or substrates are placed on linear reciprocating and oscillating square plates, and the upper surface plate of one of the lower surface plates and the lower surface plate are rigid. For example, in the traditional continuous polishing of glass plates In the surface technology, a device for continuously polishing the surface of a glass plate includes: a polishing table for transferring glass plates in one direction; and a plurality of polishing tools disposed along the glass plate transfer direction of the polishing table. . The above-mentioned polishing tool is arranged so as to withstand the eccentric rotation of the glass substrate with an eccentric axis, and to reverse the rotation phase of one of the above-mentioned polishing tools (as shown in JP-A-2-83 1 50). In addition, the apparatus for a polishing method and the use of a roll-shaped polishing pad are known as polishing tools for polishing a plate-shaped body. Moving a plate-shaped body ', such as a glass plate, causes the surface of the plate-shaped body to move on the same plane. When a plurality of roll-shaped polishing pads are arranged, the axis thereof is parallel to the surface of the plate-shaped body, and is arranged in a direction substantially perpendicular to the moving direction of the plate-shaped body. Adjacent roll-shaped polishing pads rotate in opposite directions to each other and are pressed against the plate-shaped body to polish the surface of the plate-shaped body. The above-mentioned conventional techniques are disclosed in JP-A-2-83150 and

It only conveys that the killer 21 is self-pushing and retracting, and the beam 22 of the square hollow cross section that is back to the ancient T5 is set on the upper surface plate 18 axis portion 13 degrees approximately two degrees and extends parallel to the track support frame 9 and the support support frame 9 long:-. The target 22 provides a horizontal reciprocating device 23, which is spaced from the polishing table 4 arranged in a row below. Bu Wan row horizontal reciprocating arrangement 23 includes: a rack 24 is provided on one side of the beam 22 and a linear guide 25 is arranged parallel to each other on the bottom table of the beam 22 to press f surface plate 18 pumping section 13 The compression cylinder 28 at the top is set to be suspended from the lower surface of one of the horizontal reciprocating plates 26, and a pair of guides is set to be flat on the complex plate 26 and loosely fit the linear guide 25 to the linear guide 25, and can be along the line The guide rail 2 5 moves. ¥ The cylinder rod of the compression cylinder 2 8 and the shaft portion 13 are not meshed, but if the cylinder rod is extended by the drive of the compression cylinder 28, the f end of the cylinder rod is oriented The top of the shaft portion 13 is squeezed down and compressed to the upper surface plate .: The horizontal reciprocating motor 30 can rotate forward and backward and is provided at a side end of the horizontal reciprocating plate 26 with a bracket 29, and a pinion 31 and Horizontal reciprocating motor 3-0 —The rack at the end of the shaft is engaged. When the horizontal reciprocating motor 30 rotates, the horizontal reciprocating plate 26 performs a linear movement, so when the horizontal reciprocating motor 30 reverses forward and backward, the horizontal reciprocating device 23 Reciprocates with the lower surface of the compression cylinder 28 forehead beam 22. The guide rail support frame 9 and transmission 8 rail and movable rail 7-- floor polish from 4 to extend linearly in a row on both sides of the polishing station outside of the series 4, branched executors

1231780 Jade, description of the invention (8) The floor frame 9 and the moving rail 7 are bent into an arched shape so that the sliding platform can pass through 'so as to form an endless loop, as shown in Figure 4, so that the sliding platform 10 can Cycling. The μ-track pedestal 9, the moving rail 7, and the transfer holder 8 are cut off at two intermediate portions of the support holder 9 and the holder 7. It is used to transmit the sliding platform. The suspension and two moving rails 7 of the upper surface plate 18 are arranged on a moving support frame 33. The moving support frame 3 3 is interrupted by the track support frame 9 and inserted into each short. The space portion is formed.

As shown in FIG. 2, one side surface of the movable support frame 33 is provided on a balanced bracket 36 and a shaft 35 and pivoted on a support column 34 to be rotatable. A boom 37 has a balancer 40 connected to the tilt cylinder 39 at one end-the rod 38 'tilt cylinder 39 is adjacent to the support column 34 and includes a tilt device 32. When tilted, one of the rods 38 of the cylinder 39 moves vertically, and the arm 37 rotates in the direction of the second halfway arrow. When the moving support frame 33 is tilted, the upper surface plate 18 is suspended by the sliding frame 10 from the moving frame 7 'and is tilted at a height. The tilting device U is in a tilted state as shown in FIG. 4. Next, the operation mode of the present invention will be described. The slide table 10 is stopped to hold the glass plate 16 and the pressure plate 17 is placed on the mobile support frame 33. 'The slide table 1 is moved to the position of the conveying frame 21 and reversed by the conveying motor 9 and inserted To a preset position. In other words, the cylinder 20 provided on the conveyor 21 is activated to extend its cylinder rod. ί = enter the receiver 11 of the sliding table 10, then cooperate with the conveying frame 21 ^ The conveying motor 19 rotates forward, and the conveying frame 21 and the sliding table 10 move forward to be rotated on the polishing table 4 A preset position above the upper grinding disc 3, and

The reciprocating motion is operated by the compression cylinder 28 and the horizontal reciprocating motor 30, so that the glass plate 16 is continuously polished by the parallel grinding discs 3. On the rear side of this process line, the glass plate 16 is held on the upper surface plate 8 suspended through the sliding stage, and the glass plate 16 is continuously repeatedly polished and conveyed. Therefore, the plurality of upper surface plates 18 are continuously polished until completion. After passing the plurality of grinding discs 3 and completing the polishing process, the sliding table 10 located in the temporary area of the moving support 33 is automatically or manually moved forward to the moving handle 7 of the moving support 33. When the sliding platform 10 is suspended on the moving support frame 33, if the tilting cylinder 39 of the tilting device 32 is actuated, the tilting cylinder 39 ^ a

And the arm 37 and the shaft 35 are rotated around an axis, and the mobile support frame ⑸ is placed at one end of the stagnation 柃 37 and then rotated, and the surface plate 18 is also moved by sliding on the moving rail 7 '. Therefore, the glass plate 16 adhered to the pressure plate 17 on the above table: f 18 also forms an inclined state, and displays its surface condition for the operator to see. ^ Continuing the above state and hour, the glass plate 16 in the polished state is moved: eg? Replace with a new glass plate. Furthermore, when the tilting cylinder 39 returns, the end of the 2 i stay 33 is brought closer to the end of the track support frame 9 to become a straight line. Surface plate 18 suspended above the sliding table 10

The Γ combination, the pre-Λ position ', and waits for the transport rack at the preset position: σ, and / or, after the transport rack 21 is coupled, the above action is repeated. If a plurality of sliding stands 10 at appropriate intervals are selected to be arranged at intervals: and other processing plates are used instead of the upper surface plate 18 to clear the contents of 1 as 1, the grinding disc 3 can be made at the same time. The proper / monthly cooling is obtained to make the grinding quality more stable.
