  FIG. 4 shows a cross-sectional view taken along line 4-4 of FIG. 3 illustrating an exemplary embodiment of a transport device 205 including an exemplary belt 315 and an exemplary support base 410. FIG. Unless otherwise indicated, the features of the belt 315 and the support base 410 do not depart from the scope of the present disclosure, the first plurality of belts 210, the second plurality of belts 220, and the third plurality of belts 230. It should be understood that it can be applied to any one or more of the belts alone or in combination. As shown, the belt 315 includes a first surface 451, an opposite second surface 452, and holes 455, 456 extending between the first surface 451 and the second surface 452. it can. In some embodiments, the dimension, eg, diameter, that defines the opening of the holes 455, 456 varies in the thickness direction of the belt 315 between the first surface 451 of the belt 315 and the second surface 452 of the belt 315. can do. For example, in some embodiments, the first surface 451 of the belt 315 can have a larger hole 456 that includes a relatively large size opening, and the second surface 452 of the belt 315 can be Smaller holes 455 can be placed that contain relatively small sized openings.

  In some embodiments, the support base 410 can include a support surface 411 opposite the second surface 452 of the belt 315, the belt 315 being parallel to the support surface 411 and relative to the support base 410. The direction of movement along the conveyance path 202 can be made. The support base 410 can also include a fluid passage 405 connected to the hole in the belt 315, eg, a smaller hole 455. For example, when the fluid passage 405 aligns or otherwise overlaps with the smaller hole 455 such that the fluid passage 405 is in fluid communication between the fluid passage 405 and the hole in the belt 315, eg, the smaller hole 455. A fluid connection can be made with smaller holes 455.

  In some embodiments, the glass processing apparatus 201 can include a pressure source 400 connected to the fluid passage 405 of the support base 410. For example, the pressure source 400 may be connected to the fluid passage 405 using a fluid line to provide fluid communication between the pressure source 400 and the fluid passage 405. In some embodiments, the pressure source 400 may be directly connected to the fluid passage 405 of the support base 410 so as to be in fluid communication between the pressure source 400 and the fluid passage 405. In some embodiments, the pressure source 400 may be indirectly connected to the fluid passage 405 using, for example, a fluid line. The pressure source 400 generates a vacuum in the hole 456 by drawing the fluid into the hole 456 by forward fluid flow 401 for discharging the fluid from the hole 456, and holds the glass sheet 104 on the belt 315. Any one or more of fans, blowers, pumps, vacuum devices, etc. for selectively providing a reverse fluid flow may be included. In some embodiments, forward fluid flow 401 from pressure source 400 provides a fluid cushion 475 between first surface 451 of belt 315 and second major surface 106 of glass sheet 104. In addition, the fluid can be discharged from the fluid passage 405 of the support base 410 and discharged from the holes 455 and 456 of the belt 315. Thus, in some embodiments, the glass sheet 104 can float on the fluid cushion 475 without physically contacting the belt 315. In some embodiments, the glass sheet 104 is selectively floated on the fluid cushion 475 when the belt 315 is stationary and / or when the top of the belt 315 moves along the transport path 202. Can do. Similarly, in some embodiments, the reverse fluid flow 402 from the pressure source 400 is between the second major surface 106 of the glass sheet 104 and the hole in the belt 315, eg, the larger hole 456. The fluid passage 405 of the support base 410 can exit from the holes 455, 456 of the belt 315 to provide a vacuum or adsorption force. Therefore, as shown in FIG. 5, the glass sheet 104 can be attracted so as to physically contact the belt 315. For example, the second major surface 106 of the glass sheet 104 can be attracted, eg, adsorbed, into physical contact with the first surface 451 of the belt 315. In some embodiments, the glass sheet 104 is selectively belted when there is no relative movement between the belt 315 and the support base 410 and the belt 315 is supported by the support surface 411 of the support base 410. It can be maintained in contact with 315. Further, in some embodiments, the glass sheet 104 is selectively maintained in contact with the belt 315 as the belt 315 moves along the transport path 202 relative to the support surface 411 of the support base 410. can do.

  In some embodiments, the support base 410 can include a rigid material, such as rock, granite, which is highly elastically deformed or plastic when subjected to an external load that is less than the failure strength of the material. No deformation occurs. In some embodiments, manufacturing the support base 410 from a rigid material can provide a hard planar support surface 411 that can support the belt 315. The hard planar support surface 411 can provide precise placement of the glass sheet 104 with respect to, for example, an edge processing device, eg, the grinding wheel 227 of the edge grinding device 225, in some embodiments, and the conveying device 205. The precise placement of the glass sheet 104 can be maintained over an extended period of time including, but not limited to As shown in FIG. 5, in some embodiments, the length 416 of the support surface 411 of the support base 410 defined along the transport path 202 is the length of the belt defined along the transport path 202. It can be less than this. Thus, in some embodiments, a plurality of support bases including the same or similar features as the support base 410 can be provided along the transport path 202 to support the belt 315. For example, by providing a plurality of relatively small support bases instead of one large support base, the transport device 205 can be made portable and lightweight and cost-effective.
