Sheet body transporting tray

Abstract

The invention provides a tray for single-sheet conveyance for placing thin plate-like articles one by one and conveying them which can prevent the generation of dust originated from the tray even if the trays are stacked. Resin block 8 having high wear resistance are fixed on an external frame 2 of the tray 1 for single-sheet conveyance, and form a contact portion with the stacked trays 1. Each of the resin blocks 8 is provided with a positioning portion used to vertically fitted. Further, each of the resin blocks 8 is provided with a supported portion to be supported by claws of a tray magazine.

Description

technical field [0001] The present invention relates to a tray for conveying thin plate-shaped articles loaded one by one. In particular, it relates to a tray for conveying a thin plate, which does not generate dust from the tray during conveyance, and thus does not contaminate the conveyed thin plate-shaped article (thin plate). Background technique [0002] For example, in the manufacturing process of a thin display device, etc., the technique for conveying a thin-plate-shaped article represented by a glass substrate is required. Thin plate-shaped items are prone to deformation such as twisting and bending, and may contact with the surrounding due to deformation during transportation, thereby damaging or destroying the surface. For this reason, a special container that can be loaded without deforming the thin plate-shaped article is generally used during transportation. [0003] By loading sheet-shaped articles in separate containers one at a time for conveyance, deforma...

Problems solved by technology

However, the problem with this transportation method is that in the case of temporary storage during the transportation process, it will occupy a large amount of storage space.

Another problem is that it will take a lot of work when you want to transfer it to another place

But the problem that these containers produce is: accumulate dust in the container, perhaps produce dust and contaminate the loaded article by itself when piled up.

In addition, there is a problem that the whole weight increases when stacking, which brings inconvenience to storage and transportation.

[0008] In order to put in glass substrates that become heavier due to the increase in size, the robot used is more expensive, and a crane is required to transport boxes with a total weight of about 1 ton between processes.

Since these devices are necessary, there is a problem that the introduction cost of the system is significantly increased due to the increase in the size of the transported items in the transport system using boxes

[0009] In addition, since it is very difficult to transport a box of about 1 ton by manpower, when the input manipulator or the crane stops for adjustment or repair, there is a possibility that the transport of the glass substrate may be interrupted.

For this reason, in the conventional conveying system, the manufacturing process of thin display devices is interrupted due to the stop of the input manipulator or the crane, which may lead to a decrease in the operating efficiency of the entire manufacturing process.
