Embodiment Construction
[0038]
[0039] figure 1 It is a plan view showing the layout of the workpiece processing facility 100 using the workpiece loading and unloading system A according to the embodiment of the present invention. In addition, in each drawing, X and Y represent horizontal directions perpendicular to each other, and Z represents a vertical direction. The workpiece processing facility 100 is a facility for processing a rectangular plate-shaped glass substrate as a workpiece, and includes a workpiece loading and unloading system A, a processing device B, a belt conveyor C, and a transfer device D. In this embodiment, glass substrates W1 and W2 having different sizes are processed by the same workpiece processing facility 100 . In addition, as a workpiece, it can also be applied to workpieces other than glass substrates.
[0040] Two belt conveyors C are installed on both sides of the X direction of the workpiece loading and unloading system A. Each belt conveyor C includes: two end...

A work loading / unloading system has a conveyance device for supporting rectangular plate-like work from its lower surface side, in a substantially horizontal position, and conveying the work in a substantially horizontal direction; placement sections formed in multiple stages in the vertical direction, having an opening through which the conveyance device can pass, and on which the work is placed in the substantially horizontal position; a side section in which a loading / unloading opening for the work is formed; a bottom section in which an entrance through which the conveyance device can pass is formed; a receiving cassette placed above the conveyance device; and a lifting means for relatively vertically moving the receiving cassette and the conveyance device. Lifting and lowering operation of the lifting means causes the conveyance device to be advanced into the receiving cassette, and the conveyance device unloads the work on the placement section to the outside of the receiving cassette and loads the work from the outside of the receiving cassette on to the placement section. The conveyance device has conveyance sections arranged two-dimensionally and independently driven of each other. The conveyance sections are selectively driven based on the size of the work and on that position on the placement section which is the source or destination of the conveyance of the work.
Description
technical field [0001] The present invention relates to a system for carrying workpieces such as glass substrates out of or into a storage box. Background technique [0002] Rectangular plate-shaped workpieces such as glass substrates used to manufacture thin displays are stored in storage boxes in multiple layers. Then, during workpiece processing, the workpieces are taken out one by one from the storage box and conveyed to a processing device or the like, and the processed workpieces are carried into the storage box again. Such equipment requires a loading and unloading system for loading and unloading workpieces from storage boxes. [0003] As this kind of loading and unloading system, for example, the type described in (Japanese) Unexamined Patent Publication No. 2002-167038 or (Japanese) Unexamined Patent Publication No. 2004-155569 is known, that is, a roller conveyor is arranged below the storage box. , by lifting and lowering the storage box, the workpieces are car...
