[0028] DETAILED DESCRIPTION OF THE INVENTION The embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments are shown. Whenever possible, the same reference numerals are used throughout the drawings to refer to the same or like parts. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
[0029] As used herein, the term "about" means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not, and need not be, exact, but may be approximate and / or may be greater or smaller, as appropriate, to reflect tolerances, conversion factors, rounding, measurement error, etc., and other factors known to those of ordinary skill in the art.
[0030] Ranges may be expressed herein as from "about" one value and / or to "about" another value. When such a range is expressed, another embodiment includes from the one value and / or to the other value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the value forms another embodiment. It will be further understood that the endpoints of each range are significant both in relation to the other endpoint, and independently of the other endpoint.
[0031] Any directional terms used herein—e.g., up, down, right, left, front, back, upper, bottom, upward, downward, etc.—are used only with reference to the drawings depicted and are not intended to imply absolute orientation.
[0032] Unless otherwise expressly stated, it is in no way intended that any method described herein be construed as requiring that its steps be performed in a particular order, or that any particular orientation of any apparatus be required. Thus, where a method claim does not actually recite the order in which its steps must be followed, or an apparatus claim does not actually recite an order or orientation for individual components, or where it is not otherwise specifically stated in the claim or description that the steps are to be limited to a particular order, or where a particular order or orientation for the apparatus components is not recited, no order or orientation is intended to be implied in any way. This applies to any possible non-expressive criteria of interpretation, including the sequence of steps, the flow of operations, the order of components, or the orientation of components; the obvious meaning derived from grammatical construction or punctuation; and logical matters regarding the number or type of aspects described in the specification.
[0033] As used herein, nouns include plural referents unless the context clearly indicates otherwise. Thus, for example, a reference to a component includes two or more of such components unless the context clearly indicates otherwise.
[0034] The words "exemplary" and "example" or various forms thereof are used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" or "example" is not to be construed as preferred or advantageous over other aspects or designs. Moreover, examples are provided merely for clarity and understanding and are not intended to limit or restrict in any way the disclosed subject matter or relevant portions of this disclosure. It will be recognized that numerous additional or alternative examples of various areas may have been presented but omitted for brevity.
[0035] As used herein, the terms "comprising" and "including," and variations thereof, unless otherwise expressly stated, shall be construed as synonymous and open-ended. The list of elements preceding the transitional phrase "comprising" is a non-exclusive list, and thus, elements in addition to those specifically listed in the list may be present.
[0036] The terms "substantially," "substantially," and variations thereof used herein are intended to indicate that a described characteristic is equal to or approximately equal to a value or description. For example, a "substantially flat" surface is intended to mean a flat or nearly flat surface. Furthermore, "substantially" is intended to mean that two values are equal or approximately equal. In embodiments, "substantially" can mean values that are within about 10% of each other, e.g., within about 5% of each other, or within about 2% of each other.
[0037] Modifications may be made to this disclosure without departing from the scope or spirit of the claimed subject matter. Unless otherwise specified, "first," "second," etc. are not intended to imply any temporal aspect, spatial aspect, ordering, etc. Instead, such terms are used merely as identifiers, names, etc. for features, elements, items, etc. For example, a first end and a second end generally correspond to end A and end B, or two different or two identical ends or the same end.
[0038] The present disclosure relates to glass support devices and methods for supporting a spool of glass. For purposes of this application, a "glass ribbon" can be considered to be one or more of a glass ribbon in a viscous state, a glass ribbon in an elastic state (e.g., at room temperature), and / or a glass ribbon in a viscoelastic state between the viscous and elastic states. Methods and devices for supporting a spool of glass will now be described, according to exemplary embodiments. For purposes of this disclosure, in embodiments, a glass manufacturing device can include a glass forming device that forms a glass article (e.g., a glass ribbon) from a quantity of molten material. In embodiments, the glass ribbon can be utilized in a wide range of display applications, including, but not limited to, liquid crystal displays (LCDs), electrophoretic displays (EPDs), organic light-emitting diode (OLED) displays, plasma display panels (PDPs), touch sensors, solar cells, flip phones, and the like.
[0039] As shown generally in FIG. 1 , in embodiments, an exemplary glass manufacturing apparatus 100 can include a forming apparatus 101 configured to form a glass ribbon 103. In embodiments, the forming apparatus 101 can include a slot draw apparatus, a float bath apparatus, a downdraw apparatus, an updraw apparatus, a rolling mill, or other glass forming apparatus that forms a glass ribbon. In embodiments, the forming apparatus 101 can include a feed conduit through which the glass ribbon 103 can exit the forming apparatus 101. For example, the feed conduit can include a passageway having an opening 105. The feed conduit can be oriented along the direction of gravity, such that the glass ribbon 103 can flow downward along the direction of gravity through the feed conduit.
[0040] In an embodiment, the forming apparatus 101 can define an upstream portion of a travel path 109 extending in a first direction of travel 111. The forming apparatus 101 can convey the glass ribbon 103 along the upstream portion of the travel path 109 in the first direction of travel 111. In an embodiment, the forming apparatus 101 can be located outside of a clean room environment 115, and one or more portions of the glass manufacturing apparatus 100 are located within the clean room environment 115. The clean room environment 115 can be contained within one or more walls (e.g., shown in dashed lines in FIG. 1 ) and can include a reduced level of particulates compared to the level of particulates (e.g., dust, airborne organics, vaporized particles, etc.) outside of the clean room environment 115. In an embodiment, the clean room environment 115 can be maintained at a positive pressure relative to the outside of the clean room environment 115 such that air flows from the clean room environment 115 to the environment outside of the clean room environment 115. In an embodiment, the pressure differential between the clean room environment 115 and the outside environment can be about 5 Pascals or greater. In embodiments, the cleanroom environment 115 may include an ISO (“International Organization for Standardization”) 6 cleanroom.
[0041] The glass ribbon 103 may enter the clean room environment 115 through an opening, for example, in the ceiling of the clean room environment 115. As the glass ribbon 103 enters the clean room environment 115, the glass ribbon 103 may be directed by support rollers 117 along a path of travel toward a winding device 121, where the ribbon 103 may be wound into a roll. The winding device 121 may include a spool 123, which may have, for example, a substantially circular cross-sectional shape. The spool 123 may receive the ribbon 103, where it may be wound around the spool 123 into a roll.
[0042] 2 , ribbon 103 can be wound to form a first spool of glass 201 that is received within glass support device 203. Glass support device 203 can receive and store first spool of glass 201, thus shielding first spool of glass 201 from exposure to the external environment. Glass support device 203 can be transported from a manufacturing location to a destination via air, water, and / or land transportation modes. Glass support device 203 can protect first spool of glass 201 during transportation and limit the likelihood of damage to first spool of glass 201.
[0043] The glass support apparatus 203 can include a frame 205 including a plurality of walls 207 defining an interior space 209. In embodiments, the plurality of walls 207 can be made of a rigid material resistant to deformation and damage, such as a stainless steel material. The interior space 209 of the frame 205 can be substantially hollow and sized to receive one or more glass spools. The plurality of walls 207 can be substantially closed and continuous without openings. In embodiments, the glass support apparatus 203 can include a closure 213 (e.g., a door) attached to one or more of the plurality of walls 207. The closure 213 can be movable between an open position, in which the interior space 209 can be in fluid communication with a space external to the frame 205, and a closed position, in which the closure 213 and the plurality of walls 207 can form an airtight seal. For example, one or more glass spools can be moved into and / or removed from the interior space 209 in the open position. In the closed position, an airtight seal is formed between the closure 213 and the plurality of walls 207, thereby preventing the flow of air, gases, particulates, etc. between the interior space 209 and the exterior of the frame 205 (e.g., from the interior space 209 to the exterior, or from the exterior to the interior space 209). The closure 213 can be attached to the plurality of walls 207 in several ways, for example, by a hinge that allows the closure 213 to pivot between an open position and a closed position.
[0044] The frame 205, e.g., the interior space 209, can extend along a frame axis 215, and the interior space 209 can, for example, form a substantially rectangular cross-sectional shape, although various shapes (e.g., circular, square, rectangular, etc.) are possible. In an embodiment, the plurality of walls 207 can include a first wall 217, a second wall 219, a third wall 221, and a fourth wall 223. The first wall 217 can be opposite and parallel to the second wall 219, and the third wall 221 can be opposite and parallel to the fourth wall 223. The first wall 217 can extend between and be attached to the third wall 221 and the fourth wall 223, while the second wall 219 can extend between and be attached to the third wall 221 and the fourth wall 223. In an embodiment, the first wall 217 can define a top (e.g., or top wall) of the frame 205, and the second wall 219 can define a bottom (e.g., or bottom wall) of the frame 205. The frame axis 215 can intersect the closure 213 (e.g., when the closure 213 is in the closed position) and the wall opposite the closure 213, but not the first wall 217, the second wall 219, the third wall 221, or the fourth wall 223. For example, the frame axis 215 can be substantially perpendicular to the closure 213 and substantially perpendicular to the wall opposite the closure 213 when the closure 213 is in the closed position.
[0045] Glass support device 203 can include a first surface 227 and a second surface 229 disposed within interior space 209. In embodiments, first surface 227 and second surface 229 can be spaced apart, e.g., first surface 227 and second surface 229 can be non-parallel and converge in a direction away from frame axis 215. In embodiments, first surface 227 and second surface 229 can be substantially planar. First surface 227 can extend between and be attached to third wall 221 and second wall 219, and second surface 229 can extend between and be attached to fourth wall 223 and second wall 219. In embodiments, first surface 227 can be positioned as a mirror image of second surface 229, with base surface 231 extending between first surface 227 and second surface 229. Second wall 219 can define base surface 231 such that first surface 227 is spaced apart from and free from contact with second surface 229. In an embodiment, a width of base surface 231 (e.g., the distance between first surface 227 and second surface 229) can be substantially constant along frame axis 215.
[0046] 3 shows a side view of the glass support apparatus 203 without a spool of glass disposed within the interior space 209. In an embodiment, a first end 301 of the first face 227 is attached to the third wall 221, and an opposite second end 303 of the first face 227 is attached to the second wall 219. A first end 305 of the second face 229 is attached to the fourth wall 223, and an opposite second end 307 of the second face 229 is attached to the second wall 219. By converging away from the frame axis 215, the first ends 301, 305 can be separated by a first distance 313, and the second ends 303, 307 can be separated by a second distance 315, where the first distance 313 is greater than the second distance 315. In this manner, the faces 227, 229 can be tapered. In embodiments, first distance 313 can be substantially constant along frame axis 215, e.g., first distance 313 separating first ends 301, 305 is substantially the same at all locations within interior space 209. Similarly, in embodiments, second distance 315 can be substantially constant along frame axis 215, e.g., second distance 315 separating second ends 303, 307 is substantially the same at all locations within interior space 209.
[0047] 2-3 , a first glass spool 201 and a second glass spool 241 can be supported within the interior space 209 by a first surface 227 and a second surface 229. In an embodiment, the glass spools 201, 241 can include flanges. For example, the first glass spool 201 can include a first flange 243, and the second glass spool 241 can include a second flange 245. The flanges 243, 245 can be positioned at opposite ends of the glass spools 201, 241, with the wound glass positioned between the first flange 243 and the second flange 245. In an embodiment, the first flange 243 contacts and rests on the surfaces 227, 229, and the second flange 245 contacts and rests on the surfaces 227, 229. Therefore, glass (e.g., glass disposed between flanges 243 of first spool of glass 201 and flanges 245 of second spool of glass 241) is spaced from and does not contact surfaces 227, 229. Due to the tapered orientation of surfaces 227, 229, frame 205 can support glass spools 201, 241 of several sizes. For example, surfaces 227, 229 can support glass spools 201, 241 ranging in diameter from small to large, with the different sizes of glass spools 201, 241 contacting and resting on surfaces 227, 229.
[0048] In embodiments, glass support device 203 can include one or more engagement features that can facilitate stacking and / or attachment between multiple frames. For example, with reference to FIG. 2 , first wall 217 can include first engagement feature 251, and second wall 219 can include second engagement feature 253. In embodiments, first engagement feature 251 can include a plurality of recesses (e.g., openings, depressions, indentations, etc.) that can be located at the intersections of first wall 217 and third wall 221 and first wall 217 and fourth wall 223. The recesses can extend partially, but not completely, into walls 217, 221, and 223. In embodiments, second engagement feature 253 can include a plurality of protrusions (e.g., extensions, outcrops, etc.) that can protrude outward from second wall 219. In embodiments, the plurality of protrusions can be positioned to substantially match the location and number of the plurality of recesses. For example, the distance separating the plurality of protrusions can substantially match the distance separating the plurality of recesses. Similarly, the first engagement feature 251 can include four recesses, and the second engagement feature 253 can include four protrusions. In an embodiment, the plurality of protrusions can have a size and shape that substantially matches the size and shape of the plurality of recesses. In this manner, the first engagement feature 251 can engage with a second engagement feature of a second frame (e.g., substantially identical to the second engagement feature 253 of FIG. 2) disposed above the frame 205. For example, the second engagement feature of the second frame is configured to fit within the first engagement feature 251 of the frame 205. Additionally or alternatively, the second engagement feature 253 can engage with a first engagement feature of a third frame (e.g., substantially identical to the first engagement feature 251 of FIG. 2) disposed below the frame 205. For example, the second engagement feature 253 of the frame 205 is configured to fit within the first engagement feature of the third frame.
[0049] 4 shows a cross-sectional view of the glass support apparatus 203 along line 4-4 in FIG. 3, with the first glass spool 201 and the second glass spool 241 disposed within the interior space 209 with the closure 213 in a closed position. In an embodiment, the glass support apparatus 203 can include a shaft 401 disposed within the interior space 209 and extending substantially parallel to the frame axis 215, the shaft 401 extending linearly between a first end 403 and an opposing second end 405. In an embodiment, the shaft 401 can be positioned to span the center (e.g., central opening or passage) of the first glass spool 201 and the second glass spool 241, such that the shaft 401 extends coaxially through the glass spools 201, 241. In embodiments, a first end 403 of the shaft may be attached to the closure 213, and an opposite second end 405 may be attached to an end wall 407 of the plurality of walls 207 opposite the closure 213. The end wall 407 may extend substantially parallel to the closure 213 when the closure 213 is in the closed position, and the end wall 407 is attached to the first wall 217, the second wall 219, the third wall 221, and the fourth wall 223.
[0050] The ends 403, 405 of the shaft 401 can be attached to the closure 213 and the end wall 407 in several ways. For example, the glass support apparatus 203 can include a first support structure 411 attached to the closure 213 and a second support structure 413 attached to the end wall 407. In embodiments, the first support structure 411 can have an opening sized and shaped to receive the first end 403 of the shaft 401, and the second support structure 413 can have an opening sized and shaped to receive the second end 405 of the shaft 401. In embodiments, the first support structure 411 and the second support structure 413 can be positioned such that the shaft 401 extends substantially parallel to the frame axis 215 when the ends 403, 405 are received by the support structures 411, 413. For example, the shaft 401 may extend substantially parallel to the first wall 217, the second wall 219, the third wall 221, and the fourth wall 223, and substantially perpendicular to the closure 213 and the end wall 407. In this manner, when the closure 213 is in a closed position, the shaft 401 may extend through the glass spool 201, 241 and be supported by the support structures 411, 413. When the closure 213 is in an open position, the shaft 401 may be detached from the support structures 411, 413 and removed from the center of the glass spool 201, 241.
[0051] The glass support apparatus 203 can include one or more spacers that can cushion the glass spools 201, 241 and limit the likelihood of damage to the glass spools 201, 241 when the glass support apparatus 203 is transported. In embodiments, the glass support apparatus 203 can include a first spacer 417, a second spacer 419, and a third spacer 421. The first spacer 417 can be positioned between the closure 213 and the first glass spool 201. For example, the first spacer 417 can be positioned within the interior space 209 in contact with the inner surface 425 of the closure 213 and the first flange 243 of the first glass spool 201. The second spacer 419 can be positioned within the interior space 209 in contact with the inner surface of the end wall 407 and the second flange 245 of the second glass spool 241. In an embodiment, a third spacer 421 can be disposed between the first glass spool 201 and the second glass spool 241. The spacers 417, 419, 421 can be made from an elastically deformable material (e.g., rubber, foam, etc.) that can temporarily deform in response to a load and then return to its original shape. In an embodiment, the spacers 417, 419, 421 can have an opening that can receive the shaft 401 therein, thereby allowing the spacers 417, 419, 421 to be supported by the shaft 401.
[0052] The shaft 401 and spacers 417, 419, 421 can together function to protect the glass spools 201, 241 from damage and to limit movement of the glass spools 201, 241 within the frame 205. For example, the glass spools 201, 241 can receive the shaft 401 through the center of the glass spools 201, 241. In this manner, the shaft 401 can limit movement of the glass spools 201, 241 in the first direction 426 (e.g., perpendicular to the frame axis 215 and the shaft 401) and maintain the glass spools 201, 241 in contact with the first surface 227 and the second surface 229. The spacers 417, 419, 421 can be positioned adjacent the ends of the glass spools 201, 241. Thus, the spacers 417, 419, 421 can limit movement of the glass spools 201, 241 in the second direction 427 (e.g., parallel to the frame axis 215 and shaft 401) and limit contact of the glass spools 201, 241 with the closure 213 or end wall 407. Therefore, the glass support device 203 can be moved or transported while the glass spools 201, 241 are protected within the interior space 209 and shielded from damage. Furthermore, by limiting movement of the glass spools 201, 241 within the interior space 209, the glass spools 201, 241 are maintained in a stationary, fixed position relative to the surfaces 227, 229, thereby reducing particle generation that can result from friction and movement. Reducing particle formation within the interior space 209 is beneficial to maintaining a cleanroom environment within the interior space 209. In an embodiment, the shaft 401 can maintain the glass spools 201, 241 spaced apart from and out of contact with the surfaces 227, 229, such that the glass spools 201, 241 can be suspended within the interior space 209. In this manner, the shaft 401 can restrict the glass spools 201, 241 from moving in a first direction 426, while the spacers 417, 419, 421 can restrict the glass spools 201, 241 from moving in a second direction 427.Thus, the shaft 401 can support the glass spools 201, 241 in contact with or spaced apart from the surfaces 227, 229.
[0053] FIG. 5 illustrates vertically stacked frame 205 and second frame 501. For example, during transportation and storage, it may be beneficial to stack multiple frames vertically while limiting relative movement between the frames. Engagement features 251, 253 can function to maintain one frame (e.g., second frame 501) in a fixed, stationary position relative to a second frame (e.g., frame 205). In embodiments, second frame 501 can include an engagement feature 503 disposed on a bottom wall of second frame 501. In embodiments, engagement feature 503 can include a protrusion and can be substantially similar to second engagement feature 253 shown in FIG. 2. Engagement feature 503 can interlock with engagement feature 251 of frame 205. For example, the protrusion of engagement feature 503 is received within a recess of engagement feature 251. In this way, the second frame 501 is limited in its movement relative to the frame 205, thereby reducing the tendency for it to be accidentally removed or dropped and protecting the glass spool.
[0054] FIG. 6 illustrates an additional embodiment of a glass support apparatus 203, where the glass support apparatus 203 can be sized to accept glass spools in addition to the glass spools 201, 241 shown in FIG. 2 . The glass support apparatus 203 of FIG. 6 can include a frame 205, a plurality of walls 207, a closure 213, a first surface 227, and a second surface 229. In addition, the glass support apparatus 203 can include additional surfaces for supporting the glass spools, such as a third surface 601 and a fourth surface 603. The third surface 601 can be substantially identical to the first surface 227. For example, the third surface 601 can be disposed within the interior space 209 and can extend parallel to the first surface 227, and the second surface 229 is disposed between the first surface 227 and the third surface 601. In an embodiment, the fourth surface 603 can be substantially identical to the second surface 229. For example, the fourth surface 603 can be disposed within the interior space 209 and can be spaced apart from the third surface 601, with the fourth surface 603 extending parallel to the second surface 229 and the third surface 601 being disposed between the second surface 229 and the fourth surface 603.
[0055] In embodiments, the third surface 601 and the fourth surface 603 can be spaced apart, e.g., the third surface 601 and the fourth surface 603 are non-parallel and converge in a direction away from the frame axis 215. In embodiments, the third surface 601 and the fourth surface 603 can be substantially planar. The third surface 601 can extend between and be attached to the second surface 229 and the second wall 219. The fourth surface 603 can extend between and be attached to the fourth wall 223 and the second wall 219. In embodiments, the third surface 601 can be positioned as a mirror image of the fourth surface 603, with a base surface 605 extending between the third surface 601 and the fourth surface 603. The second wall 219 can comprise the base surface 605, such that the third surface is spaced apart from and free of contact with the fourth surface 603. In an embodiment, the width of base surface 605 (e.g., the distance between third surface 601 and fourth surface 603) can be substantially constant along frame axis 215 between closure 213 and end wall 407.
[0056] The third surface 601 and the fourth surface 603 can be tapered so that a third spool of glass 611 and a fourth spool of glass 613 can be supported within the interior space 209 by the third surface 601 and the fourth surface 603. In embodiments, the third spool of glass 611 can include a third flange 615, and the fourth spool of glass 613 can include a fourth flange 617. In embodiments, the third flange 615 and the fourth flange 617 can contact and rest on the third surface 601 and the fourth surface 603. Due to the tapered orientation of the surfaces 601, 603, the frame 205 can support glass spools 611, 613 of several sizes. For example, surfaces 601, 603 can support glass spools 611, 613 ranging in diameter from small to large, with the different sized glass spools 611, 613 contacting and resting on surfaces 601, 603. In embodiments, additional shafts (e.g., substantially identical to shaft 401 shown in FIG. 4) and additional spacers (e.g., substantially identical to spacers 417, 419, 421 shown in FIG. 4) can be provided to engage glass spools 611, 613 to protect glass spools 611, 613 and limit movement (e.g., movement directions 426, 427) of glass spools 611, 613 in a manner substantially identical to that described in and for FIG. 4.
[0057] In embodiments, to further protect the glass spools 201, 241, 611, 613, one or more walls may be provided within the interior space 209 to separate each spool from the other spools. For example, a wall may be provided between the glass spools 201, 241 supported on the first surface 227 and the second surface 229, and between the glass spools 611, 613 supported on the third surface 601 and the fourth surface 603. In embodiments, the wall may extend perpendicularly between the first wall 217 and the intersection of the second surface 229 and the third surface 601. Additionally or alternatively, additional walls may be provided between the first glass spool 201 and the second glass spool 241, and between the third glass spool 611 and the fourth glass spool 613. In this manner, if one of the glass spools 201, 241, 611, 613 is damaged, for example, during shipping, the damaged glass spool may release particles (e.g., glass particles) into the air. However, due to the presence of the wall, the released particles may be isolated and contained within the area surrounding the damaged glass spool, thereby limiting the released particles from contaminating the undamaged glass spools (e.g., due to the wall blocking the released particles).
[0058] 7-10 illustrate the process of loading one or more spools of glass into a glass support apparatus 203. For example, FIG. 7 illustrates a side view of the glass support apparatus 203 fitting snugly against a wall 701 of the clean room environment 115. The wall 701 can separate the clean room environment 115 from an external environment 703 that is not maintained at the same concentration of airborne particulates. The wall 701 can have an opening 705 that defines a passageway between the clean room environment 115 and the external environment 703. In an embodiment, a door 707 can cover the opening 705 and is movable between an open position in which the opening 705 is uncovered and objects can pass between the clean room environment 115 and the external environment 703 through the opening 705, and a closed position in which the opening 705 is blocked. FIG. 7 illustrates the door 707 in the closed position.
[0059] In embodiments, the first glass spool 201 (e.g., and other glass spools 241, 611, 613) can be initially stored in the clean room environment 115 to reduce exposure of the glass spools 201, 241, 611, 613 to airborne particulates. To load the glass support device 203, the frame 205 can be positioned against the wall 701. For example, the wall 701 can have an inner surface 711 that faces and is located within the clean room environment 115, and an outer surface 713 that faces and is located within the external environment 703. The frame 205 can be placed within the external environment 703 and can be positioned adjacent the outer surface 713 and the opening 705.
[0060] FIG. 8 illustrates the wall 701, opening 705, door 707, and glass support apparatus 203 as viewed from symmetry circle 8 in FIG. 7 . The door 707 can cover the opening 705 and form a seal with the inner surface 711 of the wall 701. In this manner, the door 707 can restrict the passage of air and particulates through the opening 705, thus maintaining the clean room environment 115. While FIG. 8 illustrates the door 707 as at least partially protruding into the opening 705, the door 707 is not so limited; in embodiments, the door 707 may not protrude into the opening 705 but may cover the opening 705 and form a seal with the inner surface 711. The frame 205 can contact the outer surface 713 of the wall 701 to deliver one or more spools of glass 201, 241, 611, 613 from the clean room environment 115 to the glass support apparatus 203. For example, frame 205 and one or more of plurality of walls 207 can contact exterior surface 713 to form an airtight seal. Frame 205 can form a seal with exterior surface 713 in several ways. For example, one or more magnets can be provided between frame 205 and exterior surface 713 to form an airtight seal and maintain frame 205 in contact with exterior surface 713. Additionally or alternatively, in embodiments, a resilient material, such as, for example, a foam gasket, can be disposed between frame 205 and exterior surface 713 to provide an airtight seal. An airtight seal can be formed surrounding opening 705 such that air and particulates are restricted from moving from the external environment through the airtight seal (e.g., between frame 205 and exterior surface 713) and into opening 705.
[0061] In embodiments, in addition to the seal between the frame 205 and the exterior surface 713, the closure 213 can be attached to and sealed with the door 707. For example, the closure 213 can have a closing surface 715 facing the door 707, and the door 707 can have a door surface 717 facing the closure 213. The closing surface 715 can define the exterior surface of the door 707 outside of the glass support apparatus 203. In embodiments, the closing surface 715 can be in contact with the door surface 717, thereby forming a seal between the closing surface 715 and the door surface 717. The seal can be formed in several ways. For example, one or more magnets can be provided between the closing surface 715 and the door surface 717 to form an airtight seal and maintain the closure 213 in contact with the door 707. Additionally or alternatively, in embodiments, a resilient material, such as, for example, a foam gasket, can be disposed between the closure 213 and the door 707 to provide an airtight seal.
[0062] 9, once seals are formed between the frame 205 and the wall 701 and between the closure 213 and the door 707, the closure 213 and the door 707 can be opened. For example, in embodiments, the door 707 can be hinged and pivotable, similar to the closure 213, from a closed position (e.g., as shown in FIGS. 7-8) to an open position (e.g., as shown in FIG. 9). In this manner, the closure 213 and the door 707 can move (e.g., move together) as a unitary structure to the open position. When the closure 213 and the door 707 are opened, the seals (e.g., between the frame 205 and the wall 701 and between the closure 213 and the door 707) remain intact, and thus the clean room environment 115 is not exposed to the external environment 703. A method of supporting a spool of glass can include exposing the spool of glass 201 to the clean room environment 115 before positioning the frame 205 against the wall 701 (e.g., as shown in FIG. 7 ) and as the spool of glass 201 is fed through the opening 705. For example, when the closure 213 and door 707 are in an open position, the spool of glass 201 can remain exposed to the clean room environment 115 because the external environment 703 is sealed. In an embodiment, a method of supporting a spool of glass can include positioning the frame 205 including the interior space 209 against a wall 701 having the opening 705 such that the interior space 209 can be in fluid communication with the opening 705 and the frame 205 forms a seal with the wall 701. As used herein, fluid communication can include a gas flow path between two or more cavities, e.g., the interior space 209, the opening 705, and the clean room environment 115.
[0063] In an embodiment, the method can include feeding a spool of glass 201 from the clean room environment 115 through the opening 705 into the interior space 209 of the frame 205. For example, when the closure 213 and door 707 are open, the frame 205 is positioned to receive the first spool of glass 201. In an embodiment, an operator can move the first spool of glass 201 through the opening 705 into the interior space 209, where the first spool of glass 201 can be supported by surfaces 227, 229 (e.g., as shown in FIG. 2 ). In embodiments, one or more additional glass spools 241, 611, 613 can similarly be passed from the clean room environment 115 through the opening 705 into the interior space 209, where the one or more additional glass spools 241, 611, 613 can be supported by the surfaces 227, 229, 601, 603 (e.g., as shown in FIGS. 2-6 ). During loading of the glass spools 201, 241, 611, 613 into the interior space 209, the glass spools 201, 241, 611, 613 can remain exposed to the clean room environment 115 and not to the external environment 703 (e.g., due to a hermetic seal), thereby protecting the glass spools 201, 241, 611, 613 from airborne particulates. In embodiments, one or more glass spools 201, 241, 611, 613 are disposed within the interior space 209, so that the shaft 401 and spacers 417, 419, 421 can be moved into the interior space 209 and positioned similarly to the example in Figure 4. In this manner, the method can include positioning one or more spacers 417, 419, 421 on the ends of the glass spools 201, 241, 611, 613, where the one or more spacers 417, 419, 421 are made from an elastically deformable material.
[0064] 10 , once the one or more glass spools 201, 241, 611, 613, shaft 401, and spacers 417, 419, 421 are positioned within the interior space 209, the method can include sealing the interior space 209 using a closure 213, for example, by closing the closure 213 onto the frame 205 to seal the interior space 209. For example, the closure 213 and door 707 can be moved from an open position (e.g., as shown in FIG. 9 ) to a closed position of FIGS. 7, 8, and 10 . In the closed position, the closure 213 can seal with the plurality of walls 207, thereby forming an airtight seal and restricting the passage of air and particulates into the interior space 209. In embodiments, with the closure 213 in the closed position and the door 707 closed and sealed with the walls 701, the frame 205 can be removed and separated from the walls 701. For example, the airtight seal between the exterior surface 713 and the frame 205 can be broken, allowing the frame 205 to be removed from the wall 701. Similarly, the airtight seal between the closure surface 715 of the closure 213 and the door surface 717 of the door 707 can be broken, allowing the closure 213 to be removed from the door 707. In this manner, the glass support apparatus 203 can be removed from the wall 701 and transported to a different location.
[0065] The glass spools 201, 241, 611, 613 remain in a substantially fixed position within the interior space 209 during transport, thus reducing the likelihood of damage to the glass spools 201, 241, 611, 613 during transport. Additionally, during the process of loading the glass spools 201, 241, 611, 613 into the interior space 209, the glass spools 201, 241, 611, 613 are exposed to the clean room environment 115 and not to the external environment 703. Similarly, the interior space 209 can be maintained at an atmosphere similar to the clean room environment 115, and the interior space 209 is sealed with a closure 213. Therefore, the glass spools 201, 241, 611, 613 can be protected from airborne particulates during transport. In embodiments, upon arrival at the destination, the glass spools 201, 241, 611, 613 can be removed from the frame 205 according to the description shown in Figures 7-9. For example, with the glass spools 201, 241, 611, 613 positioned within the interior space 209, the frame 205 and closure 213 can be moved into contact with a wall and door (e.g., substantially identical to the wall 701 and door 707 shown in Figures 7-10). The closure 213 can form an airtight seal with the door, and the frame 205 can form an airtight seal with the wall. The closure 213 and door can then be moved from a closed position to an open position, thereby removing the glass spools 201, 241, 611, 613 from the interior space 209 and passing them through the opening into a cleanroom environment.
[0066] As described herein, the glass support device 203 can store and protect one or more glass spools. Additionally, the glass support device 203 can maintain a clean room environment within the interior space 209 of the glass support device 203, thereby protecting the glass spools from mechanical damage (e.g., from vibration, shaking, etc.) and also protecting the glass spools from airborne particulates that may be present in a non-clean room environment. For example, the glass support device 203 can interact with a clean room environment while maintaining a clean room environment within the interior space 209 because the closure is sealed with the frame. The glass support device 203 can be reused multiple times, thereby reducing waste associated with disposable containers. The glass support device 203 can also support multiple glass spools (e.g., one or more), and in embodiments, due to its tapered surface, can support spools of various sizes. In embodiments, the glass support device 203 can be stacked vertically, thereby allowing multiple glass support devices to be stored in a more efficient manner and reducing the tendency for them to be inadvertently removed during storage. Additionally, the glass support apparatus 203 can isolate individual spools of glass disposed within the interior space 209. For example, the glass support apparatus 203 can include walls that separate and isolate the spools of glass. In this manner, undamaged spools of glass can be protected from damaged spools of glass due to the tendency of glass spools to be less damaged during transport. In embodiments, the process of loading the spools of glass into the glass support apparatus 203 can be relatively quick, for example, taking less than about 10 minutes to complete, and the glass support apparatus 203 does not need to be cleaned after each use.
