BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for transporting a glass substrate for a liquid crystal panel that transports raw materials of glass, which is the front surface of the liquid crystal panel, between processes in a production process of a liquid crystal panel, and more specifically, a glass substrate loaded or unloaded on a tray. The position of the side bar from the frame can be changed at the same time according to the size of the frame and the glass substrate can be loaded or unloaded on the loading bar quickly without changing the position of the sensor detecting the presence or absence of the glass substrate even if the size of the glass substrate to be handled is changed. The present invention relates to a glass substrate transport tray provided with a reflection plate for detecting the presence or absence of a glass substrate.

In general, glass substrates used in the manufacturing of flat panel displays, such as thin film transistor-liquid crystal displays (TFT-LCDs), plasma display panels (PDPs), and electro luminescent (EL), are used for glass melting furnaces. The glass material dissolved in is manufactured to a predetermined size through a molding process and a cutting process.

Such glass substrates have many defects caused by various factors such as thickness, warpage, flatness, transmittance, bubbles, foreign objects, scratches, irregularities, contamination, linearity, and size error. Much attention should be paid to the transport of finished glass substrates.

Accordingly, the glass substrates cut to a predetermined size (1100 x 1300 mm) through the forming process and the cutting process of the glass are sequentially stacked in a tray and transported between the processes.

1 is a front view showing a conventional transport tray, Figure 2 is a plan view showing a cut portion of Figure 1 and Figure 3 is a side view showing a cut portion of Figure 1, the conventional transport tray is molded in a lattice form by injection A support bar which consists of a top plate 1 and a bottom plate 2 and both side bars 3 and a stopper 4 and maintains a predetermined distance (between the loaded glass substrate and the glass substrate) on the stopper 4 ( 5) is fixed and the loading bar 6 is installed on both side bars 3 at regular intervals so that the glass substrates 7 placed on the forks are sequentially stacked in a tray to be transported between processes.

After placing the conventional tray configured as described above in the loading or unloading position of the glass substrate, the glass substrate 7 placed on the fork of the forklift truck (not shown) is loaded between the loading bars 6, or the loading is performed. The glass substrate 7 placed on the bar 6 is unloaded.

Therefore, when the glass substrate 7 is placed between the loading bars 6 and the glass substrate 7 is not recognized, the new glass substrate is introduced into the loading bar 6 by using the fork of the forklift, and the glass that has been placed on the loading bar 6. Since the substrate 7 hits the fork and is broken, it must be provided with a sensing means for determining whether the glass substrate 7 is placed on the loading bar 6 before loading or unloading the glass substrate 7.

Therefore, conventionally, as shown in FIG. 2, the glass substrate 7 is installed on the loading bar 6 before the fork of the forklift is installed by installing the sensing means 8 such as photosensors inclined on both sides of the facility where the tray is located. By judging whether or not, the phenomenon in which the glass substrate 7 is damaged by the fork is prevented.

However, such a device is not provided with a sensing means 8 for judging the presence or absence of the glass substrate 7 in the tray, and is installed in a facility on which the tray is placed, so that the size of the glass substrate 7 to be loaded or unloaded is increased. Whenever the change was accompanied by inconvenience in use, which must necessarily adjust the position of the sensing means (8).

Therefore, whenever the size of the glass substrate 7 loaded or unloaded in the tray is changed between processes, the position of the sensing means 8 has to be adjusted, thus making it impossible to perform a quick operation, thereby causing a problem in that productivity is lowered.

The present invention has been made to solve such a conventional problem, and does not include a sensing means for determining the presence or absence of a glass substrate in the equipment located in the tray, the glass substrate inside and the glass substrate is loaded or unloaded The purpose of the present invention is to provide a detecting means in the fork of the forklift for loading or unloading the glass substrate to quickly load or unload the glass substrate regardless of the size of the glass substrate loaded or unloaded in the tray.

Another object of the present invention is to properly load or unload glass substrates having various sizes by using one tray by properly adjusting the position of the side bar on which the loading bar is formed according to the width direction of the glass substrate placed on the loading bar. It is.

Still another object of the present invention is to provide a wheel at the bottom of the tray so that the tray can be safely transported between nearby processes without using a forklift truck.

According to an aspect of the present invention for achieving the above object, in the glass substrate transport tray formed with a loading bar having a plurality of side bars fixed to the frame and the step bar has a stepped seating surface at regular intervals, supporting the plurality of side bars It is integrated with the member to adjust the position along the long hole formed in the frame, the support bar fixed to the rear of the frame is fixed to the reflector plate and the fork of the forklift for loading or unloading the glass substrate to detect the signal reflected by the reflector plate Provided is a tray for transporting a glass substrate provided with a reflection plate for detecting the presence or absence of a glass substrate, characterized in that a sensor is provided.
