11 is a perspective view showing another example of the fixing stopper means applied to the present invention.

This is a configuration in which the support stopper 74 is further formed in the vertical direction at the upper portion of the fixing stopper means 7 as described above.

11, when the supporting table 74 is further formed, it is possible to provide a function of maintaining the stacked state when the sheet material 200 is stacked or when it is supplied from the outside through the roller conveyor 5 in a stacked state .

FIG. 12 is a perspective view illustrating an edge supporting means applied to the present invention, FIG. 13 is a plan view showing the operating state of FIG. 12, and FIG. 14 is a plan view showing the operating state of FIG.

The corner support means 16 provided in the present invention are respectively provided on the front and rear sides of the supports 4 and two corner support means 16 provided on one support 4 are disposed in the middle of the elevation members 12 ) In the direction of the optical axis.

The edge supporting means 16 includes a support plate 162 for supporting the LM guide 161 for supporting plate to be coupled to the support 4 so as to be positioned in the traveling direction of the roller conveyor 5, The ball screws 164 for bearing corner supporting means, which are supported by bearings on the supporter 4 and are formed by symmetrical left and right screws, are rotated by a motor 163 for corner supporting means which is driven in the forward and reverse directions.

The edge plate 166 is assembled on the support plate 162 by disposing the LM guide 165 for corner support plate perpendicularly to the LM guide 161 for the support plate (axial direction of the roller conveyor 5) So that the edge plate 166 can be moved along the LM guide 165 for the edge plate by the cylinder 167 fixed to the edge plate.

And a finger LM guide 168 disposed at a right angle to the LM guide 161 for the support plate at the upper side of the corner receiving plate 166. The LM guide 168 for finger, So that the finger LM guide 168 and therefore the calibrating finger 169 can be moved by the calibrating cylinder 170 provided on the edge receiving plate 166. [

At this time, a grounding roller 171 is installed on the calibration finger 169 at a right angle so as to be in contact with the plate-like object 200.

The stacking system of the sheet material 200 of the present invention configured as described above can be manufactured by stacking pallets for packaging middle- or large-sized flat panel displays or various sheet materials 200 (sheet material) It can be used for drawing out the plate-shaped material 200 from the one fed in a laminated state. Hereinafter, the use of the present invention will be described.

When the wafers 200 are to be stacked by using the present invention, the support supporters 4 are first moved to the outside of the roller conveyor 5 by using the support moving means 9 so that the size of the wafers 200 And the lift stopper 65 and the fixed stopper 72 are moved toward the front and rear sides of the base body 2 by using the stopper moving means 8. [ In addition, the corner support means 16 provided on the front and rear of the upper end of the support 4 are also moved to the corresponding positions.

The edge receiving plate 166 of the corner holding means 16 is moved to a position below the plate-like object 200 and then the plate-shaped object 200 is fed through a feeding device (not shown) Supports everywhere.

When the plate-like object 200 is placed on the edge-receiving plate 166, the calibration finger 169 is actuated to correct the position of the plate-like object 200 which can be rotated when supplied from the feeding device. Shaped member 200 is formed in the shape of '└' so that the edge of the plate-like material 200 is inserted into the inside of the plate and the grounding roller 171 is provided. The side surface of the plate material 200 can be safely subjected to positional correction without scratch damage.

When the plate 200 is calibrated as described above, the finger 15 on the elevation member 12 located between the corner holding means 16 is operated to clamp the plate 200 in a supported state, When the plate 200 is clamped by the fingers 15, the calibrating fingers 169 of the edge support means 16 and the corner plate 166 are retracted and removed under the plate 200.

When the calibrating finger 169 or the like is removed as described above, the elevating ball screw 10 is operated by the elevating motor 96 to lower the elevating member 12 to which the finger 15 is coupled. When the elevating member 12 is lowered, the edge supporting means 16 receives the plate-like object 200 to be fed in and supplied again and receives the position of the plate-like object 200 using the calibrating finger 169 as described above And perform calibration work.
