Description

Table {TABLE}

TECHNICAL FIELD This invention relates to the table used when processing a plate glass and a liquid crystal panel, for example.

Processing of glass (for example, cutting lines in glass, beveling the edges of glass, or polishing R), or processing of liquid crystal panels (cutting edges of liquid crystal panels, cutting of large or small parts) In the case of inserting a line or cutting along a cut line, etc.), a table of the same size as that of the plate glass or the liquid crystal panel is used.

Whenever the size of a plate glass or a liquid crystal panel was changed, the table according to the size was selected, replaced, and responded.

According to this method, a large number of tables are required for each size of the plate glass or liquid crystal panel to be processed, which is not only cumbersome for management, but also requires a lot of time for changing the tables, which leads to a cost reduction due to a decrease in the processing utilization rate. It rises drastically.

In particular, since the size of a plate glass and a liquid crystal panel becomes large recently, a table also becomes large.

Therefore, there is a problem that the weight is also increased, so that handling of the table is difficult, and not only the heavy machinery such as a large crane is required, but also the time required for the replacement is significantly longer.

Accordingly, the present invention is very easy to change the size of the table, and a large number of tables are unnecessary for each size.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention provides the main table of the minimum size, the horizontal arm extended in 4 directions from this main table, and an arm for each of these sides. A plurality of subtable blocks arranged to be attached to and detached from the arm via attachment means between the main table side and the end portion of the direction protruding from the main table side; The structure which consists of a suction means provided in the main table so that a suction surface may become the same level is employ | adopted.

Further, at least an outer row of the subtable block is installed so as to be lifted by the lifting means so as to evacuate downward.

(Example)

Embodiments of the present invention will be described with reference to the accompanying drawings.

In the first embodiment of the present invention, as shown in Figs. 1 to 6, a horizontal arm 2 extending in four directions is provided in the main table 1 of the minimum size.

As shown in the drawing, the upper arm 2 is formed of two sets of two arms that pass through and intersect with the support 3 of the main table 1 (by fastening with bolts, etc.). Although it consists of the shaft 4 and the lower shaft 4, it may extend to the outer side from four sides of the main table 1 by other means.

In addition, the minimum size of the main table 1 has a planar area approximately equal to the planar area of the rectangular processed plate A of the plate glass or the liquid crystal panel that requires processing.

In addition, in the arm 2 of each side, from the side edge side of the main table 1 to the edge part of the direction which protrudes, in parallel with and detachable with the arm 2 through the suitable attachment means B, A subtable block 6 is formed.

Said subtable block 6 is made so that the length of an outer row | row may become long with respect to an inner row | line | column, is arrange | positioned in square shape by four columns, and is as shown in a figure. Although it is configured to consist of three columns, the number of columns is not limited thereto.

The attachment means B is a permeation hole 8 formed so that the upper and lower shaft members 4 penetrate the boss portions 7 on the lower surfaces of both end portions of the subtable block 6, as shown in the drawing. And a fastening bolt 9 for fastening the tip of the outer circumferential surface of the shaft 4 by bolts to the boss portion 7, but the subtable block 6 on the arm 2 by other attachment means. May be installed.

In addition, suction means C is provided on the upper surface of the main table 1 and each subtable 6 so that the suction surface (facing upward) becomes the same level.

In the case of the suction means C, as shown in the drawing, although a suction plate is provided by using a bracket 10, a suction box may be used in place of the suction plate. As shown in the figure, suction hoses (not shown in the drawings) are respectively connected to the suction panel.

In addition, the main table 1 is provided on the pivot axis d of the turning device D so that the main table 1 can be turned at 90 degrees or the like.

In the above configuration, when processing the processed plate A of the minimum size, for example, plate glass or liquid crystal panel, all the subtable blocks 6 are removed from the arm 2 on each side.

After mounting the processing plate A of the minimum size on the main table 1, the processing plate A is sucked and supported on the main table 1 by suction by the suction means C, and processed.

When the size of the processing plate A becomes larger than the minimum size, the subtable block 6 is attached to each arm 2 by using the attachment means B (1 row, 2 rows, 3 rows, etc.)

Then, on the main table 1 and the subtable block 6 (as shown in Fig. 6, on the main table 1 and the sub-table block 6 of the first column or as shown in Fig. 2, the main tables 1, 1, 2, 3) in the subtable block 6 of the third row, the working plate A is placed, and by suction by the attachment means C, in the main table 1 and the subtable block 6 of the first row shown in FIG. The processed plate A is sucked and supported on 6.

As a working example of the work plate A suctioned and supported, beveling by the grinding wheel 31 using the well-known grinding machine as shown in FIG. 7, or a grinding wheel as shown in FIG. R grinding | polishing by 31 or the process which inserts the cutting line by the cutter 32 of a well-known cutter as shown in FIG. 9 are performed.

Of course, other than the above, for example, cutting of a cutting line may be sufficient.

When performing the above various processes, the turning device D including the main table 1 and the subtable block 6 of each row slides back and forth by a guide rail and a slider as is well known. It is installed on a traveling body (not shown in the drawing), and the bolt is reversibly driven at a fixed position by the operation of a motor, and is inserted into the bolt and travels. The traveling body is driven by a nut (not shown in the drawing) provided on the sieve.

In addition, the arrangement of the subtable block 6 may be performed on each arm 2 of four sides when the processed plate A is square, and only on two opposite sides 2 when the processed plate A is rectangular. What is necessary is just to determine suitably according to the plane area of board | plate A.

In the second embodiment of the present invention, as shown in Figs. 10 to 13, at least the outer row of the subtable block 6 made of a plurality of parallels of the first embodiment is evacuated downward by suitable lifting means G. It is installed so that it can be elevated.

As the above-described configuration for elevating, the cylinder 51, which is the elevating means G, is provided on the boss portion 7 provided with the through hole 8 for the shaft 4, similar to the first embodiment, and the piston rod of the cylinder 51 is provided. Install the subtable block 6 on the (piston rod) 52.

This raises the subtable block 6 together with the piston rod 52 by the stretching action of the cylinder 51. As shown in Fig. 14, the suction surfaces of the main table 1 and the subtable block 6 have the same level, and When grinding the edge of the plate A when the table 1 and the subtable block 6 are pivotally supported to support the table, the grinding wheel 61 is used for grinding, for example, beveling with the grinding wheel 61. When the subtable block 6 is in contact with each other, as shown in Fig. 13, the subtable block 6 is evacuated while being lowered by the elevating means G to avoid contact between the grinding wheel 61 and the subtable block 6.

As a result, the edge of the processed board A can be polished smoothly.

The elevating means G is not limited to the piston rod 52 and the cylinder 51 as shown in the drawing, and the subtable block 6 for elevating is not limited to one of the outer rows formed in parallel, but also the outer row and the inner row. It is also possible to lift up or down on each side (four sides) or on two opposite sides.

As is well known, the rotary grindstone 61 is a motor 75 in which the rotary grinder 61 is mounted on a non-rotating moving base 74 in which a nut 73 is inserted into a bolt 72 that is reversibly driven at a fixed position by the motor 71. It is installed so that the position of the grindstone 61 can be adjusted.

Since the table of this invention is comprised as mentioned above, the subtable block is provided only by the main table of the minimum size or the arm extended from each side of the main table according to the size of a process board, and it spreads from small size to big size. Very simple and easy to match.

For this reason, it is necessary to prepare a plurality of tables for each size, and to solve all problems such as the drastic reduction of the operation rate due to complicated replacement work and cumbersome work that occurs during the exchange of a heavy table of a large size. I can solve it.

In addition, since the subtable block in the outer row is evacuated by the elevating means, the contact between the grinding wheel and the subtable block for polishing the edge of the workpiece can be avoided.
