Description

Conveyor for Panel Transfers {CONVEYOR FOR CARRYING PANEL}

The present invention relates to a conveyor for transferring a panel from one position to another within a defined section.

In general, a conveyor is a mechanism for automatically and continuously conveying an object such as a material or a cargo within a certain distance.

Such conveyors can be used to transport glass substrates (glasses) in semiconductor, display processes. At this time, the transfer speed with respect to the glass substrate becomes one of several factors which determine the production speed of a semiconductor or a display.

However, the improvement of the conveying speed with respect to such a glass substrate is reaching the limit by the existing method. For example, in the case of using a roller, a slip may occur when the rotational speed of the roller is increased. This is because the friction driving force is limited because the roller and the glass substrate make point contact or line contact. In addition, the tip portion of the glass substrate is struck downward when entering the roller in front of one of the rollers and collides with the roller in front of the glass substrate. In view of preventing breakage of the glass substrate due to such a collision, it is difficult to increase the rotational speed of the roller, that is, the feed speed to the glass substrate.

SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyor for conveying panels, which improves the conveying speed of the panel to be conveyed and is less likely to cause damage or slip to the panel by such a speed increase.

According to the panel conveying conveyor according to the present invention configured as described above, the panel is conveyed at an improved speed not only by the movement of the rotating motion part itself but also by the rotating motion part being moved by the revolving motion part, but the speed at which the rotating motion part rotates is conventionally known. It may not be as high as possible, so that the overall improvement in the conveying speed of the panel is less likely to cause damage or slip to the panel.

Further, by supporting and driving a pair of rolling members with respect to one support roller on both sides of the support roller, the support roller can be driven by a uniform force and stably supported. Furthermore, since the support rollers having the structural stability as described above can be configured as one conveyor, the conveyor modules can be arranged in an odd number as well as an even number, such as 2 or 3, depending on the size of the panel.

In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations.

1 is a perspective view showing a state in which three of the panel transport conveyor 100 according to an embodiment of the present invention is installed to transport one panel (P).

Referring to this drawing, one panel conveying conveyor 100 may include an orbital movement portion and a rotational movement portion.

First, the idle movement unit may include an idle loop 110 and an idle driver 120. The idle loop 110 may include a belt 111 that is generally oval shaped. The idle driver 120 may include a driving pulley 121 and an idle pulley 123. The driving pulley 121 and the idle pulley 123 are disposed at both ends of the elliptical track formed by the belt 111 to allow the belt 111 to rotate along the elliptical track in a taut state.

The rotating part may include a rotating body 130 and a rotating driving unit 140. The magnetic body 130 rotates (rotates) itself while moving (idling) along the idle loop 110. The panel O (see FIG. 5) in the form of a plate such as a glass substrate is mounted on the magnetic material 130. The rotating driver 140 drives the rotating body 130 so that the rotating body 130 rotates by itself. The rotation driver 140 may operate in conjunction with the movement of the magnetic body 130 by the idle driver 120.

The panel conveying conveyor 100 may further include a cover 150 and a frame 160.

The cover 150 may be formed to surround a portion other than a portion of the magnetic material 130 to support the panel P. FIG. As a result, foreign matter such as dust generated during the operation of the idle driving unit 120 and the rotating driving unit 140 to the panel P may be blocked by the cover 150.

The frame 160 may include a base 161, a pedestal 163, and a mounting table 165. The base 161 is in the form of a plate, and forms a bottom or skeleton for installing the orbital movement portion and the rotational movement portion. Pedestal 163 is installed on the lower side of the base 161, it is coupled to the base 161 to be adjustable height. Thereby, the horizontal or the height of the base 161 can be adjusted. The mounting table 165 may be installed to stand on the upper side of the base 161. The revolving motion part and the rotating motion part may be spaced apart from the base 161 by the mounting table 165.

According to this constitution, the panel P mounted on the rotating motion part is conveyed more quickly than when only the rotating motion part is operated by the rotating motion part itself rotating (rotating) during the large rotation (orbiting) of the rotating motion part. Can be.

In the above description, the orbiting exercise unit and the rotating exercise unit are installed on the frame 160, but the orbiting exercise unit and the rotating exercise unit may be installed to be suspended from the ceiling of the room.

In this figure, three conveyors 100 are arranged side by side to support the panel (P). If the size of the panel P is smaller than the present, two conveyors 100 may be arranged to correspond. Furthermore, if the panel P size is larger than the present, one or more conveyors 100 may be added in the current state.

The detailed configuration of the revolving movement unit and the revolving movement unit described above will be further described with reference to FIGS. 2 to 3.

First, FIG. 2 is a partially enlarged perspective view illustrating an enlarged portion of the driving pulley 121 of FIG. 1.

Referring to this figure, the idle loop 110 may include a belt 111 and a support member 112. The belt 111 is formed to form a closed curve to maintain an ellipse shape by the driving pulley 121 and the idle pulley 123 (FIG. 3). The support member 112 is provided in plural on the outer surface of the belt 111 (the surface which is not in contact with the driving pulley 121 and the idle pulley 123). The width of the support member 112 is equal to or smaller than the width of the belt 111 so as not to interfere with the pulleys 121 and 123.

The idle driver 120 may include an input shaft 122, a motor 125, and an output shaft 126 in addition to the driving pulley 121 and the idle pulley 123 described above. The input shaft 122 is an axis that receives a force for driving the driving pulley 121. The rotational force by the operation of the motor 125 is output through the output shaft 126. The output shaft 126 may be connected to the input shaft 122 by a coupler 127.

The magnetic material 130 may include a support roller 131 and a rotation rod 132. The support roller 131 advances the panel P by its rotation, supporting the panel O (FIG. 5). The uppermost part of the support roller 131 is not covered by the cover 150 (FIG. 1) to support the panel P. FIG. The rotary rod 132 extends from the center of the support roller 131 to form a rotation axis when the support roller 131 rotates itself. The rotary rod 132 may be installed to be rotatably inserted into the support member 112 of the idle loop 110.

The rotating driver 140 may include a rolling member 141 and a guide rail 145. The rolling member 141 may be formed to have a substantially circular cross section so as to be rolled with respect to the guide rail 145. The guide rail 145 may be formed to be in contact with each other by contacting the rolling member 141. In this embodiment, the rolling member 141 is a roller having a recess 142 extending along the outer circumferential surface, and the guide rail 145 is a straight bar having a protrusion 146 of a shape corresponding to the recess 142. The guide rail 145 may be generally elliptical in response to the idle loop 110. The guide rail 145 may be a straight side portion of the guide plate 147 connected to the mounting table 165.

According to this structure, by the operation of the motor 125, the output thereof is input to the input shaft 122 via the output shaft 126 and the coupler 127. The drive pulley 121 is driven to rotate by the power input to the input shaft 122. By the rotation of the drive pulley 121, the belt 111 is rotated while drawing an elliptical trajectory. The support roller 131 connected to the belt 111 by the support member 112 is moved (idle) along the elliptical trajectory by the rotation of the belt 111.

By the movement of the support roller 131, the rolling member 141 connected to the support roller 131 by the rotation rod 132 rotates itself while rubbing against the guide rail 145. Rotation of the rolling member 141 is followed by rotation (rotation) of the support roller 131 through the rotation rod 132.

As a result, the panel P receives the conveying force due to the rotation of the magnetic body 130 itself as well as the conveying force due to the movement of the magnetic body 130. However, the relative action between the panel P and the magnetic body 130 is not much different from the rotation (rotation) of the magnetic body 130 in a fixed position. This consequently does not damage the panel P or cause slippage between the panel P and the magnetic body 130 by the speed improvement, despite the improvement of the feed speed for the panel P.

The relationship between the idle drive unit 120, the magnetic body 130, and the rotary drive unit 140 will be described with reference to FIG. 3. FIG. 3 is a partial cross-sectional view taken along the line III-III of FIG.

Referring to this figure, the belt 111 is wound around the outer surface of the drive pulley 121, and the support member 112 is provided on the belt 111 so as to protrude. Rotating rod 132 is rotatably installed to support member 112. The support roller 131 connected to the rotary rod 132 is disposed on one side (left side in the drawing) of the driving pulley 121.

The first rolling member 141a which is one of the rolling members 141 may be integrally attached to the supporting roller 131. A V-shaped recess 142 may be formed along the outer circumferential surface of the first cloud member 141a in the circumferential direction. Correspondingly, the protrusion 146 of the guide rail 145 may protrude in a V shape. Thereby, the recess 142 and the protrusion 146 are brought into maximum contact with each other while in surface contact with each other, causing the rolling member 141 to be rolled against the guide rail 145. Here, the recess 142 and the protrusion 146 may be formed to correspond to each other in surface contact with each other, and may be formed in a U-shape or the like.

The second rolling member 141b, which is another one of the rolling members 141, may be disposed on the opposite side of the first rolling member 141a based on the support roller 131. The second rolling member 141b may be installed at the end of the rotary rod 132 and may also be positioned on the opposite side of the support roller 131 with respect to the driving pulley 121. The guide rail 145 is provided also corresponding to the second rolling member 141b. As the first rolling member 141a and the second rolling member 141b are disposed on both sides of the supporting roller 131 as described above, the supporting roller 131 is driven by the two rolling members 141a and 141b in a balanced manner. And his posture can be kept stable in a constant state.

The first rolling member 141a and the second rolling member 141b may be formed in a smaller size than the support roller 131. This blocks the possibility that the rolling member 141 may interfere with the panel P unnecessarily. In addition, when the rolling member 141 is wrapped by the cover 150 and the upper portion of the supporting roller 131 is exposed, the smaller rolling member 141 is smaller than the supporting roller 131 even when the cover 150 is installed. It is advantageous.

Next, another form of the above-described rotating driver 140 will be described with reference to FIG. 4. 4 is a perspective view illustrating a panel conveying conveyor 100 ′ having a rotating driver 140 ′ according to a modification of the rotating driver 140 of FIG. 2.

Referring to this drawing, the panel conveying conveyor 100 ′ according to the present modification may include a pinion 141 ′ and a rack 145 ′ as the rotation driving unit 140 ′. Here, the pinion 141 ′ may replace the roller, which is the rolling member 141 of FIG. 2, and the rack 145 ′ may replace the guide rail 145.

According to this structure, the gear of the pinion 141 'is meshed with the gear of the rack 145'. Thereby, when the rotating rod 132 is moved by the rotation of the belt 111, the gear of the pinion 141 ′ rotates while meshing with the gear of the rack 145 ′.

As such, when the pinion 141 ′ and the rack 145 ′ are employed as the rotation driving unit 140 ′, the pinion 141 ′ and the rack 145 ′ are used as the rotation driving unit 140 ′. Rotation is more surely ensured. The rotation of the pinion 141 'is connected by the rotation (rotation) of the support roller 131 as described above.

A conveying system using the above panel conveying conveyor 100 (hereinafter also including a panel conveying conveyor 100 ') will be described with reference to FIG.

5 is a conceptual view showing a panel conveyer 100 for continuously conveying the panel P by continuously disposing the panel conveying conveyor 100 according to an embodiment of the present invention.

Referring to this figure, the panel conveying conveyor 100 may be arranged in plurality in a row.

At this time, the idle loop 110 rotates in a direction R1 corresponding to the forward direction F of the panel P as described above. The rotation of the idle loop 110 is moved in the forward direction (F), and also rotates along its own rotation direction (R2) by the rotation drive unit 140 (see FIG. 2, etc.). . By these rotations, the panel P is conveyed at a high speed in the forward direction F.

At this time, in the part where the elliptical tracks between the panel transfer conveyors 100 arranged back and forth meet, the distance between the support rollers 130 is far and the panel P may be struck. In order to improve this, an idle roller 170 may be installed in the frame 160 (see FIG. 2) so that the elliptical tracks meet. According to such a structure, the concern of the sagging of the panel P in the part which the panel conveyance conveyors 100 which comprise the elliptical track | orbit meet each other can also be solved.

Such a panel conveying conveyor is not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
