The stirring device 109 may be located downstream of the clarification container 107, and the conveying container 111 may be located downstream of the stirring device 109.

In some embodiments, the stirring device 109 may include a stirring container 109a between the clarification container 107 and the conveying container 111. In some embodiments, the agitator 109b is rotatably installed in the agitating container 109a.

The outlet duct 112 provided downstream of the transport container 111 transports the molten glass 105 to the melt stretching machine 120.

The melt stretching machine 102 includes a forming container 122 having an inlet 121 through which molten glass is introduced into a groove 123 located in the upper surface of the forming container. The molten glass in the tank 123 overflows from the forming container 122 to form a glass ribbon 124, and the glass ribbon 124 is pulled down in the drawing direction 200D.

The molten glass ribbon 124 is guided by a plurality of roller devices 125 and 200 along the stretching direction 200D. FIG. 1 shows an edge roller device 125 located on a portion of the glass ribbon 124 and a pulling roller device 200 located on another portion of the glass ribbon. In some embodiments, the edge roller device 125 may be disposed closer to the groove 123 than the pulling roller device 200. The positions of the edge roller device 125 and the pulling roller device 200 can be interchanged.

The pulling roller device 200 according to the exemplary embodiment may have a function as a pulling roller device by giving a transverse stretching tension to a glass sheet, and may also have an edge roller device such as preventing attenuation of the width dimension of the glass ribbon 124 For this purpose, the orientation of the roller 201 in contact with the front and back surfaces of the glass sheet can be variously adjusted.

FIG. 2 is a perspective view of the melt drawing machine 120 to which the roller apparatus according to the exemplary embodiment is applied.

Referring to FIG. 2, a glass ribbon 124 formed of molten glass overflowing from the groove 123 of the forming container 122 is pulled down, and a plurality of roller devices 125 and 200 may be provided near the drawing path of the glass ribbon 124, the plurality of roller devices 125 And 200 has a roller that contacts the edges of the first surface S _f and the second surface S _b of the glass ribbon 124. FIG. 2 shows the melt drawing machine including the roller devices 125 and 200 at two positions (for example, the upper position and the lower position), and the scope of the present disclosure is not limited to the number and arrangement structure of the roller devices.

According to the roller apparatus 200 of the exemplary embodiment, by controlling the orientation and position of the roller 201, the transverse tensile tension in the direction perpendicular to the stretching direction 200D and the parallel to the stretching direction 200D can be controlled and adjusted Pull the tension downward. In addition, the angle of the rotation axis 202 of the roller 201 can be adjusted in a horizontal direction perpendicular to the glass ribbon stretching direction 200D, and therefore, a function of enhancing the so-called "bow-shaped profile" can be provided.

FIG. 3 is a diagram for describing changes in the orientation or position of the roller 201 of the roller device 200 according to an exemplary embodiment on the X-Y-Z plane.

In the following description, the change in the position or orientation of the roller 201 is determined according to the movement of the shaft 202 connected to the roller 201.

Referring to FIG. 3, the rollers 201 of the opposing roller device 200 are arranged to face each other, and the glass ribbon 124 having the first surface Sf and the second surface Sb is interposed therebetween. The axes 202 of the two opposing rollers 201 are substantially aligned in the X-X direction crossing the stretching direction of the glass ribbon 124. In FIG. 3, the X-Y plane represents a vertical surface parallel to the plane of the glass ribbon 124, and the X-Z plane and Y-Z plane represent the horizontal surface and the vertical surface perpendicular to the plane of the glass ribbon 124, respectively.

The change of the orientation and position of the relative roller 201 is determined according to the movement of each shaft 202. Each shaft 202 can reciprocate a predetermined distance in its axial direction, and can be pivoted within a predetermined angular range in the vertical and/or horizontal direction by providing an additional pivot structure for the center of rotation.

FIG. 4 shows an example in which the shaft 202 rotates on the X-Z plane perpendicular to the plane of the glass plate 124. With the additional pivot structure on the X-Z plane, the shaft 202 can be rotated within a predetermined angle (θ1). In some embodiments, the shaft 202 may be configured to rotate the same angle at the same time. In some specific embodiments, the shaft 202 may be configured to rotate independently within a predetermined angular range. The rotation of the axis in the X-Z plane is the movement necessary to achieve the so-called arcuate profile, so the arcuate profile can be strengthened.

FIG. 5 shows an example in which the axis rotates or tilts in the vertical downward direction on the X-Y plane parallel to the plane of the glass plate 124. The tilt is allowed by an additional tilt adjustment structure or pivot structure on the X-Y plane, and the tilt is adjusted within a predetermined angle (θ2). This downward tilt of the shaft 202 can be used to provide the glass ribbon 124 with lateral tensile tension.

FIG. 6 shows another position change of the shaft 202 that can be rotated in the X-Z plane and the X-Y plane as described above, and this position change is related to the displacement (ΔX) of the roller 201 contacting the edge of the glass plate 124 along the X-X axis.

In addition, FIG. 7 shows changes in the pitch between the rollers 201. That is, the roller 201 contacts the opposing surfaces Sf and Sb of the glass ribbon 124. Here, the interval ΔZ between the rollers 201 can be adjusted by the force applied in the ZZ direction to force the rollers 201 to be separated from the glass sheet 124 so that the rollers 201 are no longer in contact with the glass ribbon or used for buffering (such as Reduce shock). According to an exemplary embodiment, an external force may be applied to the roller 201 from an external force source including a heavy object, so that the opposite surfaces of the glass ribbon 124 may be contacted by an appropriately adjusted pressure.
