Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material processing apparatus for performing processing such as chamfering and polishing of an outer peripheral portion of a plate material.
The present invention relates to an apparatus for processing a plate material in which the workability of the plate material is improved by holding the plate material vertically.

[0002]

2. Description of the Related Art An apparatus for processing a plate material such as a glass substrate is for polishing an end face (chamfering or the like) of a rectangular glass substrate conveyed by a conveyor belt or the like. Generally, both sides of a plate member in a horizontal state are sandwiched between the belts of a pair of upper and lower two belt conveyors arranged horizontally, and a pair of front and rear plate members are rotated by a tool table which rotates around a vertical axis arranged in the middle of movement. The side is processed, and then the plate material is taken up, the direction is changed by 90 degrees, and the plate is again mounted on a conveyor having the same structure as the belt conveyor to process the remaining pair of sides.

As shown in FIG. 26, the glass substrate 2 has a guaranteed surface 21 serving as a front surface and a non-guaranteed surface 2 serving as a back surface.
2 The guarantee surface 21 is a surface on which a liquid crystal pattern or the like is to be printed in a later process, so that the surface is not damaged. The non-guaranteed surface 22 needs to protect the surface as strictly as the guarantee surface 21. There is no side. However, a portion of the guaranteed surface 21 having a width D of about 5 mm from the outer peripheral edge is a portion to be chamfered and does not print a liquid crystal pattern, and thus becomes a non-guaranteed portion 23.

However, in the former method of sandwiching a plate material with a belt, since a plate material such as glass is sandwiched between belts, abrasion due to the belt and damage due to biting of foreign matter occur, so that a protective film is attached to the surface of the plate material. Need to be protected. Further, since both sides of the horizontally placed plate are held, there is a problem that the plate is bent in the vertical direction and the processing accuracy is reduced. For example, thickness 0.7mm
However, in the case of a large rectangular plate having a side of 500 mm or more, there is a problem that it is difficult to secure a predetermined processing accuracy because bending occurs about 10 mm.

In the case of holding by a belt, since the plate is held only by the frictional force of the belt, the running of the plate material may meander. Therefore, the load applied to the processing tools on both sides becomes non-uniform. There are many problems that the traveling becomes unstable, the machining accuracy is deteriorated, and the unprocessed portion occurs. Further, there is a problem in that the apparatus is arranged in series because of the belt conveyor, and the apparatus itself becomes long, and a long space in the vertical direction is required.

[0006] When the plate is held horizontally, there is also a problem that chips and foreign matter during processing are liable to adhere to the plate such as glass. For this reason, as shown in FIG. 24, in the structure in which the bending of the plate material in the horizontal state does not occur, as shown in FIG. 24, the plate material is sucked by vacuum or magnetic force, and the turning in the horizontal plane is horizontally arranged. 2. Description of the Related Art There is a plate processing apparatus in which a plate is placed on a support and moved in the front-back or left-right direction to process the plate (see Japanese Patent Publication No. 6-41083).

In the plate processing apparatus, as shown in the figure, the lower surface of the plate is held by the plate support 28 and the swivel 25, so that the bending of the plate is eliminated. However,
Since the plate material is moved horizontally, both sides or one side of the plate material are brought into contact by the carrier, there is a problem that it is necessary to attach a protective film to the security surface 21. In particular,
As described above, the glass substrate 2 has a guaranteed surface 21 and a non-guaranteed surface 22.
5 also requires the carrier to contact and hold the assurance surface 21, which is the upper surface, so that even if it is held by vacuum or magnetic force, it will directly contact the assurance surface 21. Become. For this reason, a protective film is required on the guarantee surface 21, and a step of attaching and detaching the protective film occurs, which causes a problem that productivity is reduced.

Further, there is another problem that foreign matters such as glass powder and cutting powder easily adhere to the plate material during processing due to horizontal holding. In addition, there is a problem that the processing time is long because the processing apparatus processes the sheet material side by side. for example,
Even if the tool tables 11a, 11b, 11c, and 11d are provided vertically or horizontally as shown in FIG. 25 as in a processing apparatus disclosed in Japanese Patent Application Laid-Open No. 8-197402 (see FIG. 25), the following is required. There's a problem. That is, when the second movable table and the tool table are further added to the opposite sides of the first movable table 39 and the two sides are simultaneously processed, the first movable table 39 and the second movable table are moved. Since interference with the table occurs, the structure becomes extremely complicated, and the design becomes difficult in terms of space. In order to avoid the interference of the moving table, the first and second
It is conceivable to adopt a structure in which the moving table cantilever is held on the supporting table 38. However, in such a structure, since the processing apparatus overhangs, an eccentric load is applied to the supporting table 38 and vibration and deflection are large. Is impossible. In particular, when processing a glass substrate used in a computer or the like, it is necessary to chamfer a straight portion and a square portion in a rectangular shape. However, such a structure has a problem in processing accuracy.

A plate processing apparatus 1 according to an embodiment of the present invention.
Is basically, as shown in FIG.
Gripping means 54 (see FIG. 7) for gripping the plate material 2 loaded by the plate material loading means 3; first plate material turning means 5 for rotating the plate material 2 gripped by the gripping means 54 from a horizontal direction to a vertical direction; The plate material 2 gripped by the gripping means 54

Processing means 81, 82 for simultaneously processing the upper and lower sides or left and right sides, and a plate material 2 processed by the processing means 81, 82 is moved to a predetermined position by a plate material moving means 7, and then is gripped by a gripping means and vertically moved. It comprises a second plate turning means 6 for turning in the horizontal direction, and a plate discharging means 4 for discharging the plate 2 made horizontal by the second plate turning means 6.

As shown in the drawing, the schematic arrangement of each means of the plate material processing apparatus 1 is as follows.
It is carried in the horizontal direction to the plate material loading position B, and the plate material turning position C
After turning the plate 2 from the horizontal direction to the vertical direction in 1, the plate 2 is moved to the left and right chamfering processing position D by rotating 90 degrees clockwise by the plate moving means 7. The left and right sides of the plate material 2 are chamfered, and then the plate material moving means 7 is rotated clockwise by 90 degrees, moved to the upper and lower chamfering processing position E, and the upper and lower sides of the plate material 2 are chamfered. The plate member 2 is rotated 90 degrees clockwise by the moving means 7, and the plate member 2 is turned from the vertical direction to the horizontal direction at the turning position C2 of the plate member, and is discharged to the plate discharge position F.

By the way, the shape of the plate 2 to be processed by the plate processing apparatus 1 according to the embodiment of the present invention is, for example, a rectangle as shown in FIG.
However, before processing, the corners 2e are right-angled rectangles), the left and right sides 2a, 2b, the upper and lower sides 2c, 2d and the four corners 2e, 2e, 2e, 2e are subjected to edge polishing (chamfering or the like). Assumed to be performed. In the present embodiment, the corner 2e
Shall perform R chamfering. The reason why the chamfering is performed is to prevent the corner 2e of the glass substrate from being chipped at the time of handling the plate material 2 which is a glass substrate in a later process.

As described above, the plate member 2 as a glass substrate has a guaranteed surface 21 as a front surface and a non-guaranteed surface 22 as a back surface as shown in FIG. Guarantee 2
1 is a surface for printing a liquid crystal pattern or the like in a post-process so as not to scratch the surface;
The non-guaranteed surface 22 does not need to be as strictly protected as the guaranteed surface 21. However, in the guarantee surface 21, a width D of about 5 mm from the outer peripheral edge is a portion to be chamfered,
Since the liquid crystal pattern is not printed, the non-guaranteed part 23 is formed.

In the plate processing apparatus 1, the plate 2 to be processed is not limited to this, and the shape may not be symmetrical. Further, it may be a circular plate. In the present embodiment, a glass substrate used in a display of a computer or the like is a target of the plate material 2. Specifically, the glass substrate has a thickness of about 0.7 mm to 1.1 mm and a length of 2 mm.
70mm x 300mm to 550mm in height x 650mm in width
Something shall be processed. The object to be processed by the plate processing apparatus is not limited to the size and the material of the glass substrate, but may be any plate material that requires an end surface polishing process or the like. In particular, in the present embodiment, the plate 2 is held on one side, and the
It is suitable for processing the plate material 2 having the following.

Next, referring to FIGS. 4 and 5, the actual processing steps performed by the plate processing apparatus 1 will be described. First,
In step f1 of FIG. 4, as shown in FIGS. 2 and 4, the plate 2 is horizontally mounted on the plate carrying means 3 such that the non-guaranteed surface 22 of the plate 2 in the horizontal state is on the lower side. Specifically, the plate member 2 is manually or automatically mounted horizontally on two parallel conveyor belts 32 of the plate member carrying means 3 shown in FIGS. 13 and 14 so as to support both sides. As shown in FIG. 13, belt guides 33 are provided on both sides of the conveyor belt 32. The belt guides 33 rotate in a vertical direction while abutting on both side surfaces of the plate 2. , Can be guided. this is,
If the plate material 2 is only the conveyor belt 32, it will meander if the mounting position is shifted.
This is because the position of the plate 2 is guided by 3. As described above, in the present embodiment, the plate member 2 is not held by the frictional force of the belt unlike the related art, so that the plate member 2 is not damaged. Further, since the belt guide 33 is provided, meandering traveling is prevented, and processing accuracy is not reduced. The left conveyor belt 32 is movable left and right together with the left belt guide 33, and the guide width can be adjusted according to the size of the plate 2.

Incidentally, the conveyor belt 32 is
Contact with the non-guaranteed surface 22 of the
, But the non-guaranteed surface 22 of the plate 2 also
Since cleaning is required in a later step, it is desirable that the structure be such that foreign matter is less likely to adhere. For example, it is also possible to adopt a slit structure in which a groove of about 1 to 3 mm is provided endlessly perpendicular to the longitudinal direction of the belt. Also,
In the present embodiment, the plate 2
However, the present invention is not limited thereto, and the plate material 2 may be transported in a non-contact manner by a robot or the like. For example, it is also possible to hold and convey only the non-guaranteed portion 23 which is the outer peripheral portion of the plate 2.

Here, the timing at which the plate 2 is mounted on the conveyor belt 32 of the plate carrying-in means 3 will be described. First, after confirming that there is no plate member 2 on the conveyor belt 32 by a photoelectric sensor (not shown), the plate member 2 is mounted on the conveyor belt 32. When the plate member 2 is mounted, the conveyor belt 32 starts rotating by a signal from the photoelectric sensor, and the plate member 2 is held by a gripper 5 described later.
When the conveyor belt 32 is moved to an intermediate position with respect to the position to be gripped by 4, the conveyor belt 32 is temporarily stopped to wait for the subsequent mounting of the plate material 2. The rear plate 2 is a conveyor belt 3 under the conditions described above.
2, the conveyor belt 32 is rotated again by the signal of the photoelectric sensor in the same manner as the above-mentioned plate member 2 so that the plate member 2 is at a position where it is gripped by the gripping means 54. And the conveyor belt 32 is temporarily stopped by the sensor 31. in this way,
On the conveyor belt 32, two plate members 2 are mounted.

In step f2 of FIG. 4, when the plate 2 moves leftward on the conveyor belt 32 in FIG. 7, the presence or absence of the plate 2 is detected by a sensor 31 such as a photoelectric sensor or a camera. This is because the gripping means 54 grips the plate 2 at a predetermined position. Specifically, as shown in FIG. 13 and FIG.
Is composed of three sensors: a deceleration sensor 31a, a stop sensor 31b, and a confirmation sensor 31c. In the figure, when the plate 2 passes through the deceleration sensor 31a, the conveyor belt 32 is decelerated, the stop sensor 31b detects the passage of the plate 2, and the confirmation sensor 31b detects the presence or absence of the plate 2. Check that the plate 2 is at the stop position. These sensors 31 detect the position where the signal is turned on at the front end and then the signal is turned off once the plate material 2 has passed. Therefore, when the stop position of the plate 2 is confirmed, both the deceleration sensor 31a and the stop sensor 31b are off and off, and the presence / absence of the plate 2 is detected by the confirmation sensor 31c.

Next, at step f3, when the sensor 31 detects that the plate 2 has been stopped at a predetermined position, as shown in FIGS.
The gripping means 54 descends, and the plate material 2 is
5 is pivoted inward, that is, in the closing direction, so that it is locked in the concave portion 56 and gripped. As shown in FIG.
The concave portion 56 of the claw portion 55 of the gripping means 54 has a shape that widens toward the opening, and the portion where the plate material 2 is locked has a width T. It is assumed that the width T is slightly larger than the thickness of the plate 2 of about 0.7 mm.
The concave portion 56 of the claw portion 55 has a depth of 5 mm or less, and can be held without contacting the non-guaranteed portion 23 of about 5 mm from the outer periphery of the plate material 2. For this reason, in the plate material 2, the contact of the gripping means 54 is within 5 mm from the outer periphery, so that it is not necessary to attach the protective film to the plate material 2.

In step f4 in FIG. 4, as shown in FIG. 10, the first plate turning means 5 turns the plate 2 from the horizontal direction to the vertical direction. The first plate turning means 5 includes:
As shown in FIG. 18, a support shaft 58 is vertically supported on a base 57, and an air cylinder 51 is arranged in parallel with the support shaft 58. A crank arm 52 at the tip of the air cylinder 51 is rotatably supported and fixed. With such a structure, when the air cylinder 51 is driven, the shaft of the air cylinder 51 moves up and down, thereby turning the frame 53 from a vertical direction to a horizontal direction. As described above, the rotation of the frame 53 is performed by vertically moving the free end of the crank arm 52 fixed to the end of the support shaft 58 with the shaft of the air cylinder 51.

Next, in step f5 of FIG. 4, as shown in FIG. 11, the plate 2 gripped by the gripper 54 of the first plate turning means 5 is moved to the suction plate 112 of the plate holding means 10.
Move in the direction. As shown in FIG. 16, the suction plate 112 has a plurality of openings 111 capable of vacuum suction at four locations, and has grooves 115 as shown in the figure. When the air is sucked from the opening 111, the plate material 2 is entirely suction-fixed through the groove 115, so that the plate material 2 is vacuum-sucked to the pad surface of the suction plate 112 and only the non-guaranteed surface 22 of the plate material 2 It is possible to hold. The groove 115 has a width of about 2 mm and a depth of about 3 mm. The suction force is, for example, about 400 mm
Adsorption of the plate material 2 is possible at about HG. In this embodiment, the plate 2 is vertically held on one side.
In the case of processing, since the resistance force of the grindstone 83 applied to the plate material 2 is not so large, the above-mentioned suction force is sufficient. In addition, the suction force depends on the size of the plate material 2.
Adjust so as to change it to be larger or smaller than the above value.

As shown in FIG. 17, the base of the suction plate 112 on the back side of the suction plate 112 is clamped by a clamp lever 113 and fixed to the gantry 114 as shown in FIG. The size of the suction plate 112 can be changed according to the size of the plate material 2 to be processed. Actually, a plurality of suction plates 112 having different sizes are prepared and can be easily changed by replacing them with the clamp lever 113. It is assumed that the gantry 114 is fixed to a plate material moving means 7 described later.

Here, when the plate material 2 gripped by the gripping means 54 is attracted to the suction plate 112, the positioning of the plate material 2 by the positioning means 9 is required. As shown in FIG. 19, the positioning means 9 supports a lower side of the plate member 2 and fixes the horizontal direction by a horizontal reference roller 91.
b, 91c, a vertical reference roller 91a for fixedly positioning the right vertical side of the plate 2 and a swing roller 91d swingably disposed on the left vertical side of the plate 2;
After the plate member 2 is positioned on the horizontal reference rollers 91b and 91c and the vertical reference roller 91a, the rocking roller 91d is rocked and abuts against and presses the left vertical side so that the plate member 2 is positioned and fixed. Things.

In step f6 in FIG. 4, as shown in FIG. 12, after the plate member 2 is vacuum-sucked on the suction plate 112, the first plate member turning means 5 is retracted in the direction away from the suction plate 112, and the next step is performed. Prepare for turning the plate 2. Next, from FIG.
The step of processing the plate material 2 will be described. Step f7
Then, the plate member moving means 7 as shown in FIGS.
As a result, the plate 2 is rotated 90 degrees clockwise by the left and right processing means 81. The plate material moving means 7 uses a roller cam type index device, and is positioned and moved at every 90 degrees with a predetermined number of allocations (four in this embodiment). In the present embodiment, the plate material 2 can be held by the plate material holding means 10 provided in the plate material moving means 7 up to the maximum number of four sheets to be allocated. In the present embodiment, the first plate material turning means 5, the second plate material turning means 6, the left and right processing means 81 and the four
In the location, the assignment is made every 90 degrees, but the present invention is not limited to this. The first plate material turning means 5 and the second plate material turning means 6 may be performed by the same device, or the processing means 8 may be provided in one place, so that two or three places can be allocated. Further, in the present embodiment, the plate member moving means 7 is moved by rotation. However, the present invention is not limited to this, and may be linear or irregular movement.

In step f8 of FIG.
1, the left and right sides of the plate 2 are chamfered. In the left and right processing means 81, chamfering is performed by a grindstone 83a serving as a right processing means and a grindstone 83b serving as a left processing means. The chamfering process is shown in FIG. 23 with the right side processing means 81 on one side only. The moving shaft 84 is driven and controlled by a driving means 85 such as a Y-axis control motor to move the grindstone 83a. is there. In the present embodiment, the left and right chamfering are performed simultaneously, but the left and right processing means are synchronously processed by the NC control device of the common control room 11. As described above, it is premised that the processing trajectories of the grindstones 83a and 83b are input in advance by the NC device in the common control room 11. Accordingly, even when two corners of the plate material 2 (for example, the shape and size of R and C) having different right and left chamfer shapes are chamfered at the same time, one processing means and the other processing means are used. Simultaneously, the chamfering can be controlled. The chamfering process on both sides
As shown in FIG. 22, the left and right sides of the plate 2 are chamfered at the same time.

In the chamfering, the grindstones 83a and 83b are moved in the same direction as shown in FIG. For example, the chamfering of the first sheet material 2 is processed from top to bottom in the direction. That is, the upper corner portion 2e of the plate 2 of FIG.
After the R chamfering, the left and right sides 2a and 2b are chamfered to perform the R chamfering on the lower corner portion 2e.
Conversely, chamfering is performed from bottom to top in the direction. The third sheet is chamfered in the same direction as described above. In addition, the chamfering process is not limited to the case of processing in the same direction as shown in FIG. 22 (a), and as shown in FIG. 22 (b),
The grindstones 83a and 83b may be moved in opposite directions. In FIG. 22B, the processing direction is reversed for each plate 2 as in FIG. The grindstones 83a and 83b have a width of about 25 mm and have six grooves of about 0.7 to 1.1 mm. The type, external dimensions, and material of the grinding stone 83 are changed according to the size and thickness of the plate 2 to be processed.

After completion of the left and right chamfering, the plate 2 is rotated by the plate moving means 7 to the vertical machining means 82 as shown in step f9 of FIG. In step f10, the upper and lower surfaces of the upper and lower processing means 82 are cut.
Similarly to 1, the upper and lower sides are chamfered at the same time. Thereby, the chamfering of the left, right, upper and lower sides of the plate material 2 is completed.

Next, as shown in step f11 of FIG. 6, the plate 2 is moved to the position of the second plate turning means 6 by the plate moving means 7. Then, in step f12, the plate material 2 is gripped by the same gripping means (not shown) as the gripping means 54 of the second plate material rotating means 6, and in step f13, the gripping means of the second plate material rotating means 6 is moved to the suction plate. Moved away from 112, and in step f15,
The plate 2 is turned from the vertical direction to the horizontal direction by the second plate turning means 6. This is in the opposite direction to step f4 in FIG. Thereafter, the second plate turning means 6 is lowered to release the plate 2 held by the same holding means as the holding means 54, and the plate 2 is put on the sheet discharging means 4 as shown in step f17. By mounting, the plate material 2 is carried out by the carrying-out belt conveyor. When the plate member 2 is mounted on the plate member carrying-out means 4, the non-guaranteed surface 22 of the plate member 2 is made to be the lower surface, similarly to the case of the plate material carrying-in means 3.

In the plate processing apparatus 1 of the present embodiment, the processing speed of the plate 2 is determined by the sum of the indexing time and the processing time of the assigned rotation of the plate moving means 7.

[0044]

As described above, according to the present invention, the plate material is held upright and the outer periphery of the plate material is processed, so that the workability of the plate material is improved and the processing time is improved. It is possible to provide a plate processing apparatus in which the length is reduced. That is, since the plate material is vertically supported, the bending of the plate material does not occur, so that it is possible to stabilize the processing accuracy. Further, even when the plate material is processed by the processing means,
Foreign matter such as cutting powder does not easily adhere to the plate material. Furthermore, since the single-sided suction holding is performed vertically, it is possible to simultaneously process two sides in each processing means, thereby shortening the processing time.

Also, by holding only the non-guaranteed surface of the plate material on one side in the plate material holding means, the holder does not directly contact the guaranteed surface side of the plate material, so that a protective film is not required. In this case, it is not necessary to stick and peel off the protective film. In addition, by making the movement of the plate material moving means a rotational movement, it becomes unnecessary to lengthen the conveyor belt in the length direction as in the conventional plate material processing apparatus, so that the space can be effectively used. It becomes possible.
