  Glass substrates are used in various applications such as display devices, buildings, vehicles, photovoltaics and the like. A glass substrate is manufactured, for example, by melting a glass raw material and shaping the molten material into the shape of the substrate. If the manufactured glass substrates need to be transported using conventional methods, packaging multiple glass substrates into one glass substrate crate reduces transportation costs. For example, a laminate of glass substrates is loaded on a crate and packed using a fixing bar extending in the lateral direction (width direction) across the front surface of the top glass substrate. Both ends of the locking bar are engaged to the frame of the crate using a cam locking lever. With this configuration, high pressure can be applied to both sides of the laminate, but since the fixing bars are lifted from the laminate of the glass substrates in the central portion of the laminate, distortion may occur in the central portion of the laminate. is there.

  Thus, the clamping force applied to the stack of glass substrates in the central portion is reduced. When the stack of glass substrates is transported at this position, the glass substrates may collide with each other as the glass substrates move during transport. This can result in defects such as cracking or breakage on the glass substrates in the stack.

  Various aspects of the present disclosure provide a crate on which a glass substrate is loaded, the crate being applied to the laminate of the glass substrate to secure the laminate of the glass substrate in place.

  In some embodiments, the crate may comprise a plurality of binding units, for example at least two binding units. Thus, the crate comprising at least two coupling units may further comprise at least one connecting member connecting the restraints of the at least two coupling units to one another.

  According to the present disclosure, the central protrusion projecting forward from the central portion of the longitudinal portion of the restraint portion is the total amount of pressure applied to the laminate of the glass substrate, and particularly, the lamination of the glass substrate The amount of pressure applied to the central part of the body can be increased. As a result, the difference between the pressure applied to both sides of the laminate of the glass substrate and the pressure applied to the central portion of the laminate of the glass substrate can be minimized. Therefore, the fixing force applied to the laminate of the glass substrates can be increased by the fixing device, and a plurality of the glass substrates can be reliably packaged and transported after loading on the crate.

  1 to 3 are schematic views showing a crate according to an exemplary embodiment in which a glass substrate fixing device is fixed to a frame on which a glass substrate is loaded.

  As shown in FIGS. 1 to 3, the crate 10 includes a frame 11 and a glass substrate fixing device 100. Crate 10 is a means for packaging the glass laminate 20, ie, a laminate of multiple glass substrates, for transportation. The frame 11 includes a base 11a and a back member 11b. The glass laminate 20 is loaded on the base 11a adjacent to the back member 11b. In some embodiments, the glass laminate 20 may be loaded on the frame 11 in an upright position, as shown in FIGS. However, in a further embodiment, the glass laminate 20 may be loaded at an inclined position. In the case of inclined loading, the base 11a and the back member 11b may have a structure corresponding thereto.

  The front surface of the top glass substrate of the laminate 20 forms the front surface of the laminate. The glass substrate is laminated on the frame 11 in the direction from the back surface member 11 b to the front surface of the laminate 20. Generally, the width of the stack 20 is horizontal and the height of the stack 20 is vertical. As described herein, if the frame is a tilting frame, the vertical direction also tilts at an angle at which the frame is tilting.

  The glass substrate fixing device 100 is disposed in front of the glass laminate 20 and connected to the frame 11. In this position, the glass substrate fixing device 100 fixes the glass laminate 20 by pressing the laminate 20 from the front. For the sake of brevity, the glass substrate fastening device 100 is illustrated as being in intimate contact with the front face of the glass laminate 20, but for example at least one layer comprising buffer pads or boards, the glass laminate 20 and the glass substrate It may be disposed between the anchoring device 100 to protect the glass laminate 20. Furthermore, when the fixing of the glass laminate 20 to the crate 10 using the glass substrate fixing device 100 is completed, the crate 10 may be wrapped with a vinyl wrap or the like before transportation.

  As shown in FIGS. 4 to 7, the glass substrate fixing device 100 for fixing and packing the glass laminate 20 loaded on the crate 10 includes two or more coupling units 101 and one or more connection members 130. . Each coupling unit 101 includes a restraint portion 103, a first grip portion 150, a second grip portion 160, and a strap 140. The restraint portion 103 includes a longitudinal portion 110, a central protrusion 120, and a side protrusion 125.

  The longitudinal direction portion 110 is a member that brings the glass laminate 20 into close contact with the frame 11 by pressing the front side of the glass laminate 20 using the pressure applied by the straps 140. The longitudinal portion 110 has the shape of a bar extending across the glass laminate 20 in the lateral direction of the glass laminate 20 and is in close contact with the front side of the glass laminate 20. The present embodiment may include two or more longitudinal portions 110 in order to obtain uniform contact or securing force to the entire surface of the glass laminate 20. It may be advantageous to provide the fixation device 100 with three or more longitudinal portions 110 in order to increase the fixation force on the entire surface of the glass laminate 20. However, since the glass substrate fixing device 100 is transported by a worker, an excessive number of longitudinal portions 110 may reduce the workability, for example, by increasing the fixing and / or releasing time. The illustrated embodiment provides two longitudinal sections 110, an upper longitudinal section 110 and a lower longitudinal section 110, which are in intimate contact with the upper and lower portions of the front face of the glass laminate 20, respectively. Extend laterally. Furthermore, the upper and lower longitudinal portions 110 may be arranged parallel to one another. In some embodiments, the upper and lower longitudinal portions 110 may be connected to each other by means of a connecting member 130, but in further embodiments the upper and lower longitudinal portions may not be connected. Good. Furthermore, the pressure applied to the central portion 120 may be increased by placing each central protrusion 120 on the central portion of one of the plurality of longitudinal portions 110. The hooks 111 can be disposed at both ends of the upper longitudinal portion 110. The hook 111 serves to connect the upper longitudinal portion 110 to the first grip 150 and the second grip 160. These relationships are described in more detail below.

  As shown in FIGS. 5-8, the central protrusion 120 projects forwardly from the central portion of one of the upper and lower longitudinal portions 110. As shown in FIG. The central protrusion 120 serves to lift the strap 140 from the central portion of the longitudinal portion 110, and the strap 140 is combined like a belt with the central protrusion 120 and the longitudinal portion 110. When the strap 140 is lifted in this manner, the pressure applied to the central portion of the longitudinal portion 110 is increased. Similarly, the side projections 125 project forward from the longitudinal ends of the upper and lower longitudinal portions 110 respectively. Thus, the central projection 120 and the side projections 125 can separate the portion of the strap 140 extending between the central projection 120 and the side projections 125 from the longitudinal portion 110. Preferably, the amount by which central projection 120 projects from longitudinal portion 110 is greater than the amount by which side projection 125 projects from longitudinal portion 110.

  Generally, when the strap 140 is combined with the longitudinal portion 110 without the central protrusion 120, pressure is concentrated on both sides of the longitudinal portion 110. Accordingly, the contact force between the central portion of the longitudinal portion 110 and the front surface of the glass laminate 20 is reduced, and the fixing force to the central portion of the glass laminate 20 is thereby reduced. To prevent this, central protrusions 120 may be provided on the central portions of each of the upper and lower longitudinal portions 110 as in this embodiment. This configuration can increase the pressure applied to the central portion, which can increase the contact force between the central portion of the longitudinal portion 110 and the glass laminate 20. Furthermore, if the central projection 120 is used to increase the pressure applied to the central portion of the glass laminate 20, the pressure between the central portion and the sides where the pressure is concentrated if the central projection 120 is not used. The differences can be reduced or minimized. Thereby, a more uniform pressure can be applied to the entire surface of the glass laminate 20, whereby the fixing device 100 can further firmly fix the glass laminate 20 on the frame 11, and the glass laminate can be reliably packaged and transported. Ru.

  In some embodiments, each central protrusion 120 may include at least one hole 121 vertically passing through the central protrusion 120. Because the glass substrate securing device 100 can be operated manually, the glass substrate securing device 100 should have a minimal weight to facilitate transport or operator manipulation. The central projection 120 is only required to lift the strap 140 from the central portion of the longitudinal portion 110. Furthermore, as explained below, only the lifting height of the strap 140 affects the increase in pressure applied to the glass laminate. An increase in the length of contact of the straps 140 with the central protrusion 120 does not have a significant effect or increase on the pressure applied to the glass laminate. Thus, to reduce the weight of the glass substrate fastening device 100, the central projection 120 can be designed to have the smallest size necessary to withstand the pressure applied by the strap 140, and the holes 121 (this is not necessary). Material) can have a maximum size within the range in which the supporting force of the central protrusion 120 is not reduced.

  The connecting member 130, when present, connects the upper longitudinal portion 110 and the lower longitudinal portion 110 such that the upper and lower longitudinal portions 110 can be maintained parallel to one another. For example, the connecting members 130 may be provided as a pair and may extend vertically on both sides of the central projection 120. Furthermore, both longitudinal ends of the connecting member 130 can be connected to the upper and lower longitudinal portions 110. The connection member 130 may be connected to the front side of the longitudinal portion 110 because pressure is applied to the glass laminate 20 using the longitudinal portion 110. The connection member 130 may serve to keep the upper and lower longitudinal portions 110 parallel to one another at a predetermined distance. Furthermore, the connection member 130 enables the worker to simultaneously transport the pair of longitudinal portions 110 and to easily arrange the pair of longitudinal portions 110 positioned on the front side of the glass laminate 20. It can function as a handle. Furthermore, as explained below, the connection member 130 allows the support and hooks to be omitted from the lower binding unit. That is, if the connecting member 130 is not used, supports and hooks can be provided on both the upper and lower binding units.

  As shown in FIGS. 1 to 3, the strap 140 is a member that applies pressure to the upper and lower longitudinal portions 110 such that the longitudinal portion 110 is in close contact with the front side of the glass laminate 20. The strap 140 may be provided in the form of a bent, for example cord-type strap. Each strap 140 is combined with the front side of the longitudinal portion 110 via the central protrusion 120 and the side protrusions 125 so that the pressure applied to the longitudinal portion 110 can be adjusted. Where the strap 140 is provided as a belt as described above, the strap 140 is such that the central protrusion 120 contacts the portion of the longitudinal portion 110 via the central protrusion 120 and the side protrusions 125. Lifted by That is, the strap 140 contacts the central projection 120 and the side projections 125 but does not contact the other part of the longitudinal portion 110.

  FIG. 16 is a graph showing the results of analysis of Comparative Example 1. In Comparative Example 1, both ends of the fixing bar having no protrusion were fixed to the frame using a cam-type fixing lever. In the case of Comparative Example 1, the maximum value of stress was measured to be 137.4 MPa at both ends of the fixing bar and 0 MPa at the central portion. It will be understood that the stress for Comparative Example 1 was concentrated at both ends of the fixing bar and substantially no stress was applied to the central portion.

  FIG. 17 is a graph showing the results of the analysis of Comparative Example 2. The comparative example 2 differs from the comparative example 1 in that the shape of the constraining portion is corrected to a triangle as viewed from above. It will be appreciated that in the case of Comparative Example 2, the maximum values of stress and contact pressure were measured at both longitudinal ends and in the central portion. That is, the value of stress due to pressing was measured to be 92.5 MPa at the central portion and 190.2 MPa at both ends. The value of stress at the two sides of the triangle was measured to be 0.1 MPa. This shows that only the central part which protrudes by the maximum distance contributes to the increase in pressure. Furthermore, when Comparative Example 2 is compared with Comparative Example 1, it can be understood that the stress at both ends is also increased in Comparative Example 2, and thus the total amount of stress is increased.

  FIG. 18 is a graph showing the results of analysis of an embodiment according to the present disclosure. In the present embodiment, the protrusions are formed only at the central portion and both end portions of the longitudinal portion. As in Comparative Example 2, it will be appreciated that the stress was concentrated at both longitudinal ends and in the central portion of the longitudinal portion. Specifically, the maximum value of stress due to pressing was measured as 120.8 MPa in the central portion, 165 MPa at both ends, and 0 MPa in the portion between them. It will be appreciated that for this embodiment, the stress in the central portion is increased and the difference between the pressure at the ends and the pressure in the central portion is reduced compared to Comparative Example 2. As in the present embodiment, when the forwardly projecting portion is formed on the central portion and both side portions of the longitudinal portion, the center of the longitudinal portion is also the same as in Comparative Example 2 in which the pressure is concentrated on the central portion. The pressure can be better distributed in the part. On the other hand, the difference in pressure between the central part and the ends, whereby the force is transferred to the laminate of the glass substrate, can be reduced relative to the example of comparison 18 for the embodiment of FIG. . Thus, it will be appreciated that restraints having protrusions only at the central and end portions can distribute pressure evenly and reduce the weight of the fixation device.

  According to this embodiment, one end of the strap 140 can be fixed to the first grip 150 described below. The second grip 160 comprises a shaft 163. A strap 140 extending from the first grip 150 is wrapped around the shaft 163 and extends beyond the shaft 163. The other end of the strap 140 extending beyond the shaft 163 is positioned to overlap the portion of the strap 140 extending between the first grip 150 and the shaft 163 and then these two portions of the strap Are coupled to one another using a coupling member 170. That is, the coupling member 170 couples together the two parts of the strap that extend from the shaft 163. The connecting member 170 may be a buckle. In addition, the strap 140 may be guided by a plurality of guides 180 and 185 arranged in front of the front of the central projection 120 and the side projections 125. Guides 180 and 185 establish a path for the strap 140 to travel by forming a loop on the front of the central projection 120 and in front of the side projections 125. Forming the plurality of guides 180 and 185 on the path where the strap 140 is fastened can prevent the strap 140 from coming off during or after fastening the strap 140, thereby improving the reliability of the glass substrate fastening device 100. .

  To connect the pair of straps 140 and longitudinal portions 110 to the frame 11 as described above, the glass substrate securing device 100 may include a first grip 150 and a second grip 160. The grips 150 and 160 can be aligned with the longitudinal portion 110.

  The first grip 150 may be disposed on upper and lower portions of the right side wall of the frame 11. Furthermore, the upper and lower first grips 150 may be arranged at the same distance as the distance between the upper longitudinal portion 110 and the lower longitudinal portion 110. The first grip 150 secures the right end of the strap 140. Furthermore, the first grip 150 regulates the amount of pressure applied by the strap 140 to the longitudinal portion 110 by pulling and winding the strap 140. That is, the worker can adjust the amount of pressure applied to the stacked body 20 of the glass substrates stacked on the frame 11 by operating the first holding unit 150.

  As shown in FIGS. 9 to 12, each first gripping portion 150 includes a main body 151 and a bobbin 152. The main body 151 is fixed to the right side wall of the frame 11 and serves to support the bobbin 152 engaged with the main body 151. The bobbin 152 is a member that substantially fixes a corresponding one of the straps 140. As the bobbins 152 rotate, the corresponding straps 140 are wound around them, whereby tension is applied to the straps 140. In this regard, the bobbin 152 engages the body 151 such that the bobbin 152 can rotate on its vertical axis. As shown in FIGS. 9-12, the bobbins 152 engage the body 151 at positions where the bobbins 152 extend through the opposing upper and lower horizontal bracket plates of the body 151. Specifically, the upper portion of the bobbin 152 projects beyond the upper horizontal bracket plate of the main body 151, and the remaining portion of the bobbin 152 is disposed between the opposing upper and lower horizontal bracket plates of the main body 151. Ru. The bobbin 152 has a slit 152 a in a portion disposed between the upper horizontal bracket plate and the lower horizontal bracket plate of the main body 151. The strap 140 extends toward the longitudinal portion 110 after passing through the slit 152a. In this case, since one end of the strap 140 must be fixed to the bobbin 152, the one end of the strap 140 may be thicker than the width of the slit 152a so that the one end of the strap 140 can not pass through the slit 152a. Alternatively, the one end of the strap 140 may be fixed to the bobbin 152 using a separate receiving member, or may be fixed directly to the bobbin 152.

According to this embodiment, the degree to which the strap 140 is wound around the bobbin 152 in the first direction can be adjusted using a torque wrench. For example, the degree to which the strap 140 is wound may be adjusted so that the maximum amount of pressure applied to the strap 140 is 200 kgf (1.961 kN) / cm ^{2 to} 500 kgf (4.903 kN) / cm ² . This use of a torque wrench can numerically adjust the amount of tension applied to the strap 140. Thus, the pressure can be accurately and uniformly applied to the entire stack of glass substrates stacked on the plurality of frames 11. To this end, it is preferable to angle the head of the bobbin 152 so that a torque wrench can be used.

  Each first gripping portion 150 is a reverse rotation preventing portion in order to maintain the strap 140 in the pressing position where pressure is applied to the protrusions 120 and 125 and the longitudinal portion 110 by applying tension to the strap 140. Including 153. The reverse rotation preventing portion 153 is a device that prevents the bobbin 152 from rotating in the opposite direction, and includes a sawtooth wheel 153a and a claw 153b. The saw toothed wheel 153 a is provided on the outer periphery of the upper portion of the bobbin 152 protruding above the upper horizontal bracket plate of the main body 151. With this configuration, when the bobbin 152 rotates, the saw toothed wheel 153 a rotates with the bobbin 152. The pawl 153b is pivotally disposed on the portion of the body 151 adjacent to the serrated wheel 153a, and more particularly on the upper horizontal bracket plate of the body 151 adjacent to the serrated wheel 153a. The claws 153b allow the claws 153b to rotate in a first direction in which the serration wheel 153a and the bobbin 152 are wound around the outer circumference of the bobbin 152 while the serration wheel 153a is in the opposite direction to the first direction. By preventing rotation in the second direction (i.e., reverse), the serrations 153a are engaged to prevent the strap 140 from being unwound from the outer periphery of the bobbin 152. Thus, the glass substrate fixing device 100 according to the present embodiment can maintain the fixing force with respect to the glass laminate 20 without interruption using the reverse rotation preventing portion 153. This ratcheting mechanism allows tension to be set in predetermined increments.

  The second grip 160 may be disposed on the upper and lower portions of the left side wall of the frame 11. The upper and lower second grips 160 may be disposed at positions corresponding to the upper and lower first grips 150. In each second grip 160, the shaft 163 acts as a re-orienting shaft such that the straps 140 extending from the first grip 150 are re-oriented towards the first grip 150. The shaft 163 of the second grip 160 causes the strap 140 to wrap around it. Specifically, the shaft 163 of the second grip 160 guides the left end of the strap 140 and reorients towards the first grip 150. The left end of the strap 140 extending from the second grip 160 towards the first grip 150 is the extension of the strap 140 extending between the first grip 150 and the second grip 160. The parts are superimposed and then the two parts are combined with one another using a buckle type connection member 170.

  The upper first grip 150 and the upper second grip 160 may include supports 150a and 160a, respectively. The supports 150a and 160a are respectively disposed on the first grip 150 and the second grip 160 so that the supports 150a and 160a can pivot in the direction of the upper longitudinal part 110. The supports 150a and 160a are in the form of bars. The hooks 111 arranged at both ends of the upper longitudinal part 110 can be arranged on the supports 150a, 160a.
