Description

  The present invention relates to a buffer member for a plate material transport tray, and is easily bent by a glass plate, for example, a square or rectangular substrate such as a glass substrate for display used to form a display panel of a liquid crystal display device, or by its own weight. It transports, transports and transports plate-shaped articles made of thin metal plates and supports them in the tray so that they can be stacked.Thickness is extremely thin, contributing to thinner trays, enabling multi-stage stacking. Product transportation efficiency will be improved.

  Conventionally, a display panel of a liquid crystal display device is usually formed by enclosing liquid crystal between a pair of glass substrates for display that are arranged to face each other. When such a display panel is manufactured in a factory, a glass substrate for display is transported to the display panel manufacturing factory. The glass substrate is used not only for the display panel of a liquid crystal display device but also for the manufacture of display panels for various display devices.

  In addition, in order to obtain a display panel, there is a semi-finished display panel in which electrodes and the like are formed on the surface of a glass substrate.

  Recently, glass substrates having a thickness of 0.7 mm or less have been used for various display panels. In addition, with the increase in the size of the display panel, the glass substrate carried into the manufacturing factory is also enlarged, and a rectangular glass substrate having a side of 1.3 m or more is also carried into the factory.

  Since thin glass substrates with such a large area are easy to bend, there is a method of transporting them in a state where they are spaced at an appropriate interval in order to reduce the impact, but each glass substrate is bent during transportation. Adjacent glass substrates may come into contact with each other and be damaged.

  As a method for meeting such a demand, for example, as a packaging spacer of a glass substrate with a transparent conductive film, a transparent glass of one glass substrate is formed in a frame shape with a synthetic resin such as a polyfluorinated ethylene resin, a polypropylene resin, or a nylon resin. A glass substrate with a transparent conductive film in which a plurality of glass substrates are stacked and supported by contacting along the peripheral edge of the surface of the conductive film and the peripheral edge of the back surface of another glass substrate stacked adjacent to the glass substrate. There was a packing spacer as a cushioning material (see Patent Document 1).

  By the way, in order to transfer and carry at a time by stacking a plurality of glass substrates, it is necessary to provide an appropriate space between the glass substrates, and the total bulk increases. Assuming a transport space area of a predetermined size and height for stacking and transferring a single glass substrate at a time, the number of glass substrates that can be transferred and transported at one time is the above-mentioned conventional transparent number. For example, when a transporting / transporting method using a packaging spacer for a glass substrate with a conductive film is employed, the transport space region is limited and the transporting space region is reduced. As a result, when the glass substrate is transferred and stored, the number of glass substrates relative to the space occupied by the transport space region is reduced, resulting in a problem that the space efficiency is lowered.

  Furthermore, a large area glass substrate with a side length of 1.3 m or more is as heavy as about 5 kg, and when there are 20 or more glass substrates, it is transported and transported by one worker. There is a problem that it can not be done.

Thus, in order to solve the above problems, conventionally, for example, a plate material transport tray for storing one glass substrate has been proposed. The tray for conveying the plate material is formed in a substantially dish shape from a frame frame surrounding the front, rear, left and right circumferences and a bottom plate provided on the lower surface of the frame frame so as to surround the circumference of the glass substrate as the article to be conveyed. There was something.
Japanese Utility Model Publication No. 3-29474

  However, the conventional packaging spacer of the glass substrate with a transparent conductive film described in Patent Document 1 is formed in a frame shape with a synthetic resin. For example, the packaging spacer is installed on the bottom plate of the tray as a buffer member. When a single thin glass substrate having a large area is carried on the frame, the height of the frame frame for one tray is equal to the thickness of the packaging spacer and the thickness of the glass substrate. In addition, since the total height including the clearance considering the bending of the glass substrate is required, the height is considerably high. In addition, when the glass substrate is transported by stacking trays using the above-described conventional glass substrate packing spacers with transparent conductive film, the thickness of the packing spacer as a cushioning material is the upper and lower when the trays are stacked. Therefore, the height of the frame of the tray itself must be increased. Therefore, the packaging spacer of the conventional glass substrate with a transparent conductive film described in Patent Document 1 is accompanied by an increase in the height of the frame frame of the tray and an increase in the height when the glass substrate is transported by the tray. In terms of weight increase, there was a limit in increasing the number of stacked trays in order to increase product transportation efficiency.

  Moreover, in order to reduce the thickness of the packing spacer as a cushioning member installed on the tray with a synthetic resin, there is a limitation on the molding method. It is difficult to form a thin film, and there is a drawback that the clearance in the tray is eventually reduced in supporting the glass substrate.

  The present invention solves the above-mentioned conventional problems, reduces the thickness of the buffer member itself on which a plate-like article made of a glass plate or a metal plate having a large deflection due to its own weight is placed, and makes glass by a tray. When transporting substrates, keep the height of the frame frame of the tray low, make it light and easy to handle, ensure sufficient clearance above and below, and stack the trays when transporting articles to be transported The number of sheets can be increased to improve product transportation efficiency, and the structure can be simplified and mass-produced.
