The present invention relates to an apparatus and a method for loading a sheet of paper into a robot arm which is a sheet paper feeding device for supplying sheet paper to a glass substrate. More particularly, the sheet of paper is large in feeding sheet paper supplied between glass substrates to be loaded. The present invention relates to an apparatus and a method for loading misalignment into misalignment into the clamping means of the interlude feeder so that safe and accurate feeding of interleaved liquor is achieved without easily causing damage or misalignment.

In general, the glass substrate to be manufactured by melting is transported through a processing line and then loaded on a mounting table, and contact between the glass substrates and defects thereof may be generated.

Glass substrates are used in the optical field and thin film type precise surface treatment is performed, so even in the field where glass substrates are applied even with the generation of minute defects, the reaction of light reflection or refraction through the defect occurs and due to the optical interference due to this In particular, in the case of products in the display field, deterioration of image quality is caused, so glass substrates having minute defects should be treated as defective products.

Therefore, even in the step of loading and transporting the finished glass substrate, the glass substrate may be damaged due to careless handling or storage problems. In particular, a plurality of thin glass substrates having a large thickness and a large area are stacked. Since there is a high possibility that minute defects are generated due to friction and foreign matter involvement at the contact surface because of loading and transporting, a method for preventing such defects is required.

As a method, it is possible to prevent friction and involvement of foreign materials between the glass substrates and to provide a slight elasticity between the glass substrates when they are stacked to compensate for the occurrence of stress and deformation due to pressure on the contact surface. The slip sheet is inserted.

In the case of small glass substrates, the area covered by the person in charge of the process could cover the entire area of the glass substrate. Therefore, a separate means for feeding paper sheets was not required. Since this working area does not cover the entire area of the glass substrate, a mechanical apparatus and method are required.

Therefore, a device for supplying sheet paper for glass substrates, such as a robot arm, has been devised. More specifically, it is an omni-directional movable robot arm having a plurality of clamping means. The clamping means are horizontally arranged to clamp one side of the paper in the same area. After that, an apparatus for feeding interlayer paper between glass substrates was used in such a manner that paper sheets were loaded on the stacked glass substrates, then another glass substrate was loaded, and paper sheets were fed again.

1 is a side view schematically showing a sheet paper feeding device for a glass substrate.

As shown in the figure, the sheet paper feeding device for the glass substrate moves in a plane and the robot arm 20 is operably mounted, and the robot arm 20 connected to the plurality of joints from the body 10 to be almost omni-directional. And a clamping means 30 installed at the free end of the robot arm 20 to clamp the slip sheet.

The body 10 has a base 12 on which the moving means 11 is installed at a lower end thereof, and is provided with a vertical axis rotating portion 14 of a tooth shape so as to enable precise rotation about the vertical axis on the base 12. At the upper side of 14), a pneumatic or hydraulic actuator 16 for generating a driving force required for the interleaver sheet feeding device is rotatably installed about the vertical axis, and the horizontal axis rotating part 18 rotates about the horizontal axis of the robot arm on one side of the actuator. Is formed.

Robot arm 20 is the first arm 22 is mounted around the horizontal axis of the rotation portion 18 of the body 10, and one side is bent to the free end of the first arm 22 is rotatably operated in the longitudinal direction The first articulation part 24, which is mounted so as to be mounted, the second arm 26, which is mounted on the other side of the first articulation part 24, and the second arm 26 so as to be rotatable or bent in a longitudinal direction at a free end thereof. A second joint portion 28 to be mounted, and a third arm 29 diffractively mounted to the second arm 26 by the second joint portion 28.

The clamping means 30 is mounted on one side of the third arm 29 and has a structure that can be bent or rotated in the longitudinal direction with respect to the third arm 29, and has a tong shape to detachably clamp one side of the slip sheet. It is composed.

The operation of the sheet paper feeding device for glass substrates having such a structure is as follows.

When the person in charge of the process rests on the table 40 to clamp the sheet to the clamping means 30 and one side of the sheet is adjusted to slightly protrude out of the table 40, the moving means 11 mounted on the base 12. As the) moves, the body 10 is moved to a position where the clamping means 30 is easily accessible to a part of the protruding side of the slip sheet seated on the table 40.

When positioned in the proper position, the robot arm 20 mounted on the body 10 rotates and bends about the first and second joints 24, 26 while the first to third arms 22, 26, 29 are rotated. Is moved to a predetermined position, and at the same time the clamping means 30 is also moved to be adjacent to the slip sheet.

When the clamping means 30 is positioned in a position where clamping of the slip sheet is possible, the clamping means clamps the slip sheet by a lump-like structure, and once the slip sheet is firmly clamped, the centers of the first and second joints 24 and 26 are likewise centered. As the first to third arms 22, 26, and 29 are moved, the slip sheet clamped by the clamping means 30 is drawn out from the table 40 by the interlocking of the vertical axis rotating portion 14 and the horizontal axis rotating portion 18. The body 10 and the robot arm 20 move together to be loaded by the moving means 11 provided in the base 12 and are stacked on the surface of the glass substrate as in the case of pulling out the kanji. It is operated to properly position the kanji.

When the sheet is placed on the glass substrate, other glass substrates are stacked and stacked on the sheet.

Such a conventional paper sheet feeding device prevents the risk of defects or partial stress concentration on the surface of the glass substrate due to contact or foreign matter between the glass substrates being laminated, thereby preventing the risk of damage. The loading of the substrate can be completed.

However, such a sheet feeding device has a plurality of clamping means for clamping a portion of a large area sheet as the area of the sheet is increased when feeding sheet paper having a size corresponding to a glass substrate having a larger size than a conventional glass substrate. In this case, each clamping means clamps a uniform area, and at the same time, if the weight of the entire sheet is not evenly distributed in the clamped area, the sheet may be torn, especially when clamping by a plurality of clamping means. Since the same area is clamped to the means to load the sheet so that the total weight of the sheet is evenly distributed, it is desirable that the sheet is clamped correctly without misalignment, and such precise sheet loading process cannot be carried out manually by hand. Very difficult and delays Easy to be damaged land, and therefore the process is not smooth mothamyeo is made, there was a non-self it is to further load a sheet of paper separator sheets feeder problems.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the weight of the whole sheet of paper is evenly distributed to prevent the occurrence of clamping such as tearing of the sheet of paper by the sheet paper feeding device while the sheet of paper with a large area is loaded on the glass substrate. It is an object of the present invention to provide an apparatus and method for loading glass sheets on a glass substrate in which the weight of the sheet of paper ticked by the clamping means to be loaded can be evenly distributed in the portion of the sheet of paper clamped.

In order to achieve the above object, the present invention provides a glass substrate loading device, wherein at least two or more plates are aligned on a horizontal line on the table to which the sheet is seated, so that the sheet is stopped or driven, and the sheet is straight or rotated. In the method of loading a glass substrate, characterized in that it comprises a rolling unit for moving, and a sensing unit for detecting the misalignment of the moving sheet installed in the rear of the rolling unit to interlock so that the rolling unit is individually turned on or off. A step in which the slip sheet is seated on the table, a step in which the slip sheet is placed in contact with the roller, a step of detecting the position of the slip sheet being moved, and a step in which the movement of the slip sheet is stopped when the slip sheet is detected at a predetermined position. It is characterized by including.

Such a characteristic configuration and the effects thereof according to the present invention will be more clearly understood through detailed description of the invention with reference to the accompanying drawings.

2 to 4 are a plan view, a side view, and a front view respectively showing a sheet loading device for glass substrates according to the present invention, Figure 5 is a flow chart showing a sheet loading method for a glass substrate according to the present invention.

As shown in the sheet substrate loading apparatus for glass substrates according to the present invention, the table 110 on which the sheet is placed, and at least two or more are arranged in a horizontal line on the table 110, and the sheet is straightened by stopping or driving individually. Or a rolling unit 120 that rotates and a sensing unit 130 that interlocks the rolling unit 120 to be individually turned on or off by detecting misalignment of the rolled paper that is installed and moved behind the rolling unit 120. do.

Table 110 is flat and has a large enough area to be seated on a large glass substrate, the concave-convex 116 is formed on one side to maintain a horizontal state and partly exposed when the kanji is seated in an appropriate state.

Table 110 may be preferably formed of a plurality of layers to form a plurality of layers as a single assembly by the table frame 112, the lower end of the table frame 112 support means for stably supporting the table frame ( 114).

The rolling part 120 is connected to the table frame 112 and is rotatably mounted to the roller support member 122 and the roller support member 122 for supporting the rolling part 120 adjacent to the table 110. The roller mounting member 124, the roller 126 mounted on one side of the roller mounting member 124 and rotating, the roller mounting member 124, and the roller 126 and the roller mounting member 124 are rotated. It includes a roller motor 123 to interlock.

The roller motor 123 has a rotating shaft set so as to rotate about an axis parallel to the clamped side edges of the supplied slip sheets, and a roller mounting member 124 and a roller mounting member rotatably mounted with respect to the roller support member 122. The roller 126 rotatably mounted on one side of the 124 is also configured to have the same axis of rotation as the roller motor 123.

The driving force of the roller motor 123 is preferably connected by a belt (not shown) or the like to rotate the roller 126, and the roller mounting member 124 also rotates about the roller support member 122. 123 is linked with.

Preferably, the roller 126 may be rotated or reversely rotated about the rotation axis, and the roller mounting member 124 may be slightly rotated and reversedly rotated about the roller support member 122, thereby providing the roller 126. It has a structure that is moved to a position in contact with the surface of the table 110 or slightly raised.

The sensing unit 130 is mounted on the bottom of the table 110 to detect the position of the slip sheet that is seated and moved on the table 110. Preferably, the slip sheet is clamped to the clamping means 154 of the sheet feeding apparatus 150. The plurality of sensing units 130 are installed adjacent to an end portion of the side where the slip sheet is finally entered so as to detect a state of completely entering the clamped position.

The sensing unit 130 is interlocked with the rolling unit 120 to stop the roller on the side where the selvage is detected by the sensing unit 130 is stopped, and the roller on the side where the selvage is not detected is continuously rolled in contact with the rolled sheet. One side is configured to continue to frictionally move by the roller 126.

The interleaver sheet feeding device 150 is formed of a plurality of joints and arms 152 to enable almost omnidirectional operation, and the clamping means 154 formed at the distal end is a forceps, and the clamping means 154 is a table 110. In the state in which the edges are aligned to the side where the uneven portion 116 is formed, it is possible to partially clamp the edges of the portions where both sides are exposed through the recesses, and the plurality of joints and the arms 152 It has a structure operable to appropriately arrange on the surface of the glass substrate to be pulled out completely from the table 110, the clamped by the drive.

The operation and method of the interlayer loading system for glass substrates configured as described above are performed as follows.

As shown in FIG. 5, the method for arranging the sheet of paper for glass substrates on the glass substrate includes steps (S10) in which sheet paper is seated on the table, step (S20) in which the sheet of paper is seated in contact with the roller, and moving. And a step (S30) of detecting the position of the slip sheet to be detected, and stopping the movement of the slip sheet when the slip sheet is detected at a predetermined position (S40).

The slip sheet is manually seated on the table 110 and adjusted to a position where the roller can be contacted (S10).

When placed in a position that can be contacted to be frictionally moved by the rolling unit 120, the slip sheet loading system 100 is driven. First, the sensing unit 130 is a position where the slip sheet is clamped by the slip sheet feeding device 150. It is sensed whether the uneven portion 116 side and the edge are aligned and arranged together, and if it is determined that it is an inappropriate position, the roller motor 123 is operated.

As the roller mounting member 124 rotates slightly as the roller motor 123 moves, the roller 126 comes into contact with the surface of the slip sheet seated on the table 110, and the roller 126 rotates in contact. The interleaver is also moved by the frictional force (S20).

Preferably, the rolling unit 120 is arranged in a plurality of lines arranged at an equidistant distance from the concave-convex portion 116 to move the interlayer while rotating by contacting and rotating at various points on the surface of the interleaver, more preferably the sensing unit 130 is also uneven As a plurality of lines are arranged in a line at an equidistant distance from the unit 116, the moving slip sheets are misaligned, and only a part of them is detected by the detector 130 (S30), and only some of the plurality of detectors 130 detect the slip sheets. Rotation of the roller 126 of the rolling unit 120 adjacent to the sensing unit 130 that detects the slip sheet is stopped (S40).

However, even if the roller 126 of the rolling part 120 is stopped, the contact state with respect to the slip sheet is maintained, so that the point where the contact rotation is rotated by the other rolling part 120 is moved relative to the stopped spot to support the slip sheet as a whole. The misalignment of the kanji is corrected while being rotated about (S32).

While the misalignment of the kanji is corrected while continuing to move around the stationary point (S32), the kanji part of the moving side is also asymptotically detected by the sensing unit 130, and similarly adjacent to the sensing unit 130 that detects the kanji. The roller 126 of the rolling part 120 also stops operation but maintains contact to become a support point relative to other moving points.

When all the sensing unit 130 detects the kanji, since one side of the kanji is aligned without misalignment with respect to one side where the uneven portion 116 of the table 110 is formed, it is determined that the kanji is placed in a desired position. Since the side of the slip sheet located in the uneven portion 116 is exposed at both sides from the uneven portion, the sheet feeding device 150 approaches the uneven portion 116 and clamps the exposed portion of the clamping means 154 from both sides of the table. Kanji can be taken out from 110 (S50).

Preferably all clamping means approaching equidistantly with respect to the edge of the side where the uneven part 116 of the table 110 is formed, since the slip sheets are loaded unaligned when a plurality of clamping means 154 are provided. If 154 clamps the kanji in the same operation, it will clamp the same area, so that the total weight of the kanji is evenly distributed to all the clamping means 154 in the clamped portion without damaging the kanji as much as possible while not misaligning it. In this state, it is possible to supply the interlayer accurately on the glass substrate.

According to the preferred embodiment of the present invention as described above, in feeding the interlayer paper supplied between the glass substrates to be loaded, so that the safe and accurate feeding of the interstitial paper is made without the easy occurrence of damage or misalignment when the large paper is large It is possible to load the kanji into the clamping means of the kanji supply device exactly.
