The present disclosure relates to an apparatus and a method for fixing a plurality of glass substrates arranged as a laminated body on a crate, and more specifically, a pressure applied to both sides of the laminated body of the glass substrates and a glass substrate. It relates to a fixed device that minimizes the difference from the pressure applied to the central portion of the laminate.

Glass substrates are used in a variety of applications such as display devices, buildings, vehicles, photovoltaic cells and the like. A glass substrate is manufactured, for example, by melting a raw material of glass and forming the molten material into the shape of the substrate. When it is necessary to transport the manufactured glass substrate by using a conventional method, a plurality of glass substrates are packed in one glass substrate crate to reduce the transportation cost. For example, a laminate of glass substrates is loaded on a crate and packed using a fixing bar extending laterally (widthwise) across the front surface of the leading glass substrate. Both ends of the fixing bar are engaged with the crate frame using a cam-type fixing lever. With this configuration, high pressure can be applied to both sides of the laminate, but the fixing bar is lifted from the glass substrate laminate at the center of the laminate, which may cause distortion in the center of the laminate. be.

Therefore, the fixing force applied to the laminated body of the glass substrate at the central portion is reduced. When the laminate of glass substrates is transported at this position, the glass substrates may collide with each other due to the movement of the glass substrates during transportation. As a result, this can cause defects such as cracks or breaks in the glass substrate in the laminate.

Various aspects of the present disclosure provide a crate on which a glass substrate is loaded, wherein the crate is a force applied to the laminate of the glass substrate to secure the laminate in place. And in particular, the amount of force applied to the central portion of the laminate of the glass substrate, thereby the pressure applied to both sides of the laminate of the glass substrate and the pressure applied to both sides of the laminate. The difference from the pressure applied to the central portion of the laminate of the glass substrate can be minimized.

According to the embodiments disclosed herein, the crate may include: frames; and at least one binding unit. The frame may include a base and a back member, the laminate of glass substrates is loaded onto the base adjacent to the back member, and the widths and heights of the laminate intersect perpendicular to each other. The at least one coupling unit is: a longitudinal portion extending across the laminate in the width direction of the laminate and a central portion of the longitudinal portion in a direction perpendicular to the front surface of the laminate. Restraint including a central protrusion protruding from; a first grip and a second grip aligned with the longitudinal portion of the restraint and secured to the back member of the frame; and a strap. The strap is fixed to the first and second grips so as to be in contact with the central protrusion and extends between the first grip and the second grip. The strap can include a strap, which applies a force to the front surface of the laminate via the central protrusion and the longitudinal portion.

In some embodiments, the crate may comprise a plurality of binding units, eg, at least two binding units. Thus, the crate comprising at least two coupling units may further comprise at least one connecting member connecting the constraint portions of the at least two coupling units to each other.

According to the present disclosure, the central protrusion protruding forward from the central portion of the longitudinal portion of the restraint is the total amount of pressure applied to the laminated body of the glass substrate, and in particular, the laminate 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 laminated body of the glass substrate and the pressure applied to the central portion of the laminated body of the glass substrate can be minimized. Therefore, the fixing device can increase the fixing force applied to the laminate of the glass substrates, and the plurality of glass substrates can be reliably packed and transported after being loaded on the crate.

Further, for example, a torque wrench can be used to adjust the degree to which the strap is wrapped around the bobbin, which allows the pressure to be applied accurately and uniformly to the entire laminate of glass substrates loaded on multiple crates. ..

Further, according to the present disclosure, the connecting member connecting the restraining portions of the plurality of coupling units can facilitate the handling of the fixed device.

Further, the guides arranged at the front of the central protrusion and the side protrusion can prevent the strap from coming off during or after the strap is fastened.

Further, by removing the surplus material, the weight of the glass substrate fixing device can be reduced, whereby the transportation of the fixing device can be facilitated, and the workability of the fixing device can be improved.

In a further embodiment, a method of fixing a glass substrate to a crate is disclosed, the method comprising loading a plurality of the glass substrates onto the crate, the crate comprising a frame including a base and a back member. The plurality of glass substrates are loaded on the base adjacent to the back member to form a laminate of the glass substrates, and the laminates of the glass substrates have a width and a height that intersect with each other vertically. To prepare for.

It may be provided with a restraint, including a central protrusion protruding from. The at least one coupling unit may further include a first grip and a second grip, the first and second grips being aligned with the longitudinal portion of the restraint. It is fixed to the back member of the frame. The at least one coupling unit may include a strap, which is secured to the first and second grips so as to be in contact with the central protrusion and the first grip and the first grip. Extending between the grips of 2, the method may further include the step of applying force to the front surface of the laminate through the restraint by applying tension to the strap.

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. The crate 10 is a means for packing a glass laminate 20, that is, a laminate of a plurality of glass substrates for transportation. The frame 11 includes a base portion 11a and a back surface member 11b. The glass laminate 20 is loaded on the base portion 11a adjacent to the back surface member 11b. In some embodiments, the glass laminate 20 may be loaded onto the frame 11 in an upright position, as shown in FIGS. 1 to 3. However, in a further embodiment, the glass laminate 20 may be loaded in an inclined position. In the case of inclined loading, the base portion 11a and the back surface member 11b may have a structure corresponding to the base portion 11a and the back surface member 11b.

The front surface of the glass substrate at the head 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 11b toward the front surface of the laminated body 20. Generally, the width of the laminated body 20 is in the horizontal direction, and the height of the laminated body 20 is in the vertical direction. As described herein, when the frame is an inclined frame, the vertical direction is also inclined at an angle at which the frame is inclined.

The glass substrate fixing device 100 is arranged in front of the glass laminate 20 and is connected to the frame 11. At this position, the glass substrate fixing device 100 fixes the glass laminate 20 by pressing the laminate 20 from the front. For brevity, the glass substrate fixing device 100 is shown as being in close contact with the front surface of the glass laminate 20, but at least one layer including, for example, a cushioning pad or board, the glass laminate 20 and the glass substrate. It may be placed between the fixed device 100 and the glass laminate 20 to protect it. Further, 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 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 frame 11 includes two or more coupling units 101 and one or more connecting members 130. .. Each coupling unit 101 includes a restraint 103, a first grip 150, a second grip 160, and a strap 140. The restraint 103 includes a longitudinal portion 110, a central protrusion 120, and a side protrusion 125.

The longitudinal portion 110 is a member that firmly 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 strap 140. The longitudinal portion 110 has the shape of a bar extending laterally across 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 fixing force with respect to the entire surface of the glass laminate 20. In order to increase the fixing force on the entire surface of the glass laminate 20, it may be advantageous to provide the fixing device 100 with three or more longitudinal portions 110. However, since the glass substrate fixing device 100 is transported by an operator, an excessive number of longitudinal portions 110 may reduce workability, for example, by increasing the fixing and / or fixing release time. The illustrated embodiment provides two longitudinal portions 110, namely the upper longitudinal portion 110 and the lower longitudinal portion 110, which are in close contact with the upper and lower portions of the front surface of the glass laminate 20, respectively. And it extends laterally. Further, the upper and lower longitudinal portions 110 may be arranged parallel to each other. In some embodiments, the upper and lower longitudinal portions 110 may be connected to each other using a connecting member 130, but in a further embodiment, the upper and lower longitudinal portions may not be connected. good. Further, the pressure applied to the central portion may be increased by disposing each central protrusion 120 on the corresponding central portion of the plurality of longitudinal portions 110. Hooks 111 can be arranged at both ends of the upper longitudinal portion 110. The hook 111 serves to connect the upper longitudinal portion 110 to the first grip portion 150 and the second grip portion 160. These relationships will be described in more detail below.

As shown in FIGS. 5-8, the central protrusion 120 projects forward from the corresponding central portion of the upper and lower longitudinal portions 110. The central protrusion 120 serves to lift the strap 140 from the central portion of the longitudinal portion 110, which is combined with the central protrusion 120 and the longitudinal portion 110 like a belt. When the strap 140 is lifted in this way, the pressure applied to the central portion of the longitudinal portion 110 increases. Similarly, the side projecting portion 125 projects forward from the longitudinal end portions of the upper and lower longitudinal portions 110, respectively. Therefore, the central protrusion 120 and the side protrusion 125 can separate the portion of the strap 140 extending between the central protrusion 120 and the side protrusion 125 from the longitudinal portion 110. It is preferable that the amount of the central protrusion 120 protruding from the longitudinal portion 110 is larger than the amount of the side protrusion 125 protruding from the longitudinal portion 110.

Generally, when the strap 140 is combined with the longitudinal portion 110 without the central protrusion 120, the pressure is concentrated on both sides of the longitudinal portion 110. Therefore, the contact force between the central portion of the longitudinal portion 110 and the front surface of the glass laminate 20 is reduced, and as a result, the fixing force of the glass laminate 20 to the central portion is reduced. In order to prevent this, the central protrusion 120 may be provided on the central portion of each of the upper and lower longitudinal portions 110 as in the present embodiment. This configuration can increase the pressure applied to the central portion, thereby increasing the contact force between the central portion of the longitudinal portion 110 and the glass laminate 20. Further, when the pressure applied to the central portion of the glass laminate 20 is increased by using the central protrusion 120, the pressure between both side portions where the pressure is concentrated when the central protrusion 120 is not used and the central portion. The difference can be reduced or minimized. As a result, a uniform pressure can be applied to the entire surface of the glass laminate 20, whereby the fixing device 100 can more firmly fix the glass laminate 20 on the frame 11, and the glass laminate 20 can be reliably packed and transported. The glass.

In some embodiments, each central protrusion 120 may include at least one hole 121 that vertically passes through the central protrusion 120. Since the glass substrate fixing device 100 can be manually operated, the glass substrate fixing device 100 should have a minimum weight so that it can be easily transported or operated by an operator. The central protrusion 120 is only required to lift the strap 140 from the central portion of the longitudinal portion 110. Further, as described below, only the height at which the strap 140 is lifted affects the increase in pressure applied to the glass laminate. Increasing the length of contact of the strap 140 with the central protrusion 120 does not have a significant effect or increase on the pressure applied to the glass laminate. Therefore, in order to reduce the weight of the glass substrate fixing device 100, the central protrusion 120 can be designed to have the minimum size required to withstand the pressure applied by the strap 140, and the hole 121 (which is unnecessary). Can have a maximum size within a range in which the bearing capacity of the central protrusion 120 does not decrease.

If a connecting member 130 is present, it connects the upper longitudinal portion 110 and the lower longitudinal portion 110 so that the upper and lower longitudinal portions 110 can be kept parallel to each other. For example, the connecting members 130 may be provided as a pair and may extend vertically on both sides of the central protrusion 120. Further, both the longitudinal ends of the connecting member 130 can be connected to the upper and lower longitudinal portions 110. Since the pressure is applied to the glass laminate 20 by using the longitudinal portion 110, the connecting member 130 can be connected to the front side of the longitudinal portion 110. The connecting member 130 can serve to keep the upper and lower longitudinal portions 110 parallel to each other at a predetermined distance. Further, the connecting member 130 allows the worker to simultaneously transport the pair of longitudinal portions 110 and easily arrange the pair of longitudinal portions 110 positioned on the front side of the glass laminate 20. Can function as a handle. Further, as described below, the connecting member 130 allows the support and hook to be omitted from the lower coupling unit. That is, when the connecting member 130 is not used, the support and the hook can be provided on both the upper coupling unit and the lower coupling unit.

As shown in FIGS. 1 to 3, the strap 140 is a member that applies pressure to the upper and lower longitudinal portions 110 so 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, eg cord-shaped strap. Each strap 140 is combined with the anterior side of the longitudinal portion 110 via a central overhang 120 and a side overhang 125 so that the pressure applied to the longitudinal portion 110 can be adjusted. When the strap 140 is provided like a belt as described above, the strap 140 has a central protrusion 120 such that the strap 140 contacts a portion of the longitudinal portion 110 via the central protrusion 120 and the side protrusion 125. Lifted by. That is, the strap 140 contacts the central protrusion 120 and the side protrusion 125, but does not contact the other portions of the longitudinal portion 110.

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

FIG. 17 is a graph showing the results of the analysis of Comparative Example 2. Comparative Example 2 is different from Comparative Example 1 in that the shape of the restraint portion is modified to be a triangle when viewed from above. In the case of Comparative Example 2, it will be appreciated that the maximum values of stress and contact pressure were measured at both the longitudinal end and the center. That is, the value of the stress due to pressing was measured as 92.5 MPa at the central portion and 190.2 MPa at both ends. The stress value at both hypotenuses of the triangle was measured as 0.1 MPa. This indicates that only the central portion protruding by the maximum distance contributes to the increase in pressure. Further, when Comparative Example 2 is compared with Comparative Example 1, it can be understood that the stress at both ends also increased in Comparative Example 2, and therefore the total amount of stress increased.

FIG. 18 is a graph showing the results of analysis of an embodiment according to the present disclosure. In this embodiment, the protrusions are formed only in the central portion and both end portions of the longitudinal portion. It will be appreciated that, as in Comparative Example 2, the stresses were concentrated at both the longitudinal ends of the longitudinal portion and at the central portion. Specifically, the maximum value of the stress due to pressing was measured as 120.8 MPa at the central portion, 165 MPa at both ends, and 0 MPa at the portion between them. It will be appreciated that for this embodiment, the stress at the central portion has increased and the difference between the pressure at both ends and the pressure at the central portion has decreased compared to Comparative Example 2. When the protrusions protruding forward are formed in the central portion and both side portions of the longitudinal direction portion as in the present embodiment, the pressure is also concentrated in the central portion as in Comparative Example 2, the center of the longitudinal direction portion. The pressure can be better distributed in the portions. On the other hand, the difference in pressure between the central portion and both ends (thus transferring the force to the laminate of the glass substrate) can be reduced with respect to the embodiment of FIG. 18 as compared to Comparative Example 2. .. Therefore, it will be appreciated that restraints with protrusions only in the central and both ends can evenly distribute the pressure and reduce the weight of the fixed device.

According to this embodiment, one end of the strap 140 can be fixed to the first grip portion 150 described below. The second grip portion 160 includes a shaft 163. The 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 so as to overlap a portion of the strap 140 extending between the first grip 150 and the shaft 163, and then these two parts of the strap. Are connected to each other using a connecting member 170. That is, the connecting member 170 connects the two portions of the strap extending from the shaft 163 to each other. The connecting member 170 may be a buckle. Further, the strap 140 may be guided by a plurality of guides 180 and 185 arranged in front of the central protrusion 120 and in front of the side protrusion 125. The guides 180 and 185 set the path for the strap 140 to travel by forming loops in front of the central protrusion 120 and in front of the side protrusion 125. By forming the plurality of guides 180 and 185 on the path to which the strap 140 is fastened, it is possible to prevent the strap 140 from coming off during or after the strap 140 is fastened, thereby improving the reliability of the glass substrate fixing device 100. ..

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

The first grip portion 150 may be arranged on the upper and lower portions of the right side wall of the frame 11. Further, the upper and lower first grip portions 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. Further, the first grip portion 150 adjusts the amount of pressure applied to the longitudinal portion 110 by the strap 140 by pulling and winding the strap 140. That is, the worker can adjust the amount of pressure applied to the laminated body 20 of the glass substrates loaded on the frame 11 by operating the first grip portion 150.

As shown in FIGS. 9 to 12, each first grip portion 150 includes a main body 151 and a bobbin 152. The main body 151 is fixed to the right 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 one of the straps 140. By rotation, the bobbin 152 winds the corresponding strap 140 around it, thereby applying tension to the strap 140. In this regard, the bobbin 152 engages the body 151 so that the bobbin 152 can rotate about its vertical axis. As shown in FIGS. 9-12, the bobbin 152 engages the body 151 at a position where the bobbin 152 extends through the facing 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 body 151, and the rest of the bobbin 152 is located between the facing upper and lower horizontal bracket plates of the body 151. To. The bobbin 152 has a slit 152a in a portion arranged between the upper horizontal bracket plate and the lower horizontal bracket plate of the main body 151. After passing through the slit 152a, the strap 140 extends toward the longitudinal portion 110. 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 cannot 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 by 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 . Using a torque wrench in this way, the amount of tension applied to the strap 140 can be numerically adjusted. As a result, the pressure can be applied accurately and uniformly to the entire laminated body of the glass substrates loaded on the plurality of frames 11. For this purpose, it is preferable to angle the head of the bobbin 152 so that a torque wrench can be used.

Each first grip portion 150 is a reverse rotation preventing portion in order to maintain the strap 140 at a pressing position where pressure is applied to the protrusions 120 and 125 and the longitudinal portion 110 by applying tension to the strap 140. 153 is included. The reverse rotation prevention unit 153 is a device for preventing the bobbin 152 from rotating in the opposite direction, and includes a saw gear 153a and a claw 153b. The saw gear 153a 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. Using this configuration, when the bobbin 152 rotates, the saw gear 153a rotates together with the bobbin 152. The claws 153b are pivotally located on a portion of the body 151 adjacent to the saw gear 153a, more specifically on the upper horizontal bracket plate of the body 151 adjacent to the saw gear 153a. The claw 153b allows the claw 153b to rotate the saw gear 153a and the bobbin 152 in the first direction in which the strap 140 is wound around the bobbin 152, while the saw gear 153a is opposite to the first direction. It engages the saw gear 153a so as to prevent the strap 140 from unraveling from the outer circumference of the bobbin 152 by preventing it from rotating in the second direction (ie, vice versa). In this way, the glass substrate fixing device 100 according to the present embodiment can maintain the fixing force to the glass laminate 20 without interruption by using the reverse rotation prevention unit 153. With this ratchet mechanism, the tension can be set in a predetermined increment.

The second grip portion 160 may be arranged on the upper and lower portions of the left side wall of the frame 11. The upper and lower second grips 160 may be arranged at positions corresponding to the upper and lower first grips 150. In each second grip 160, the shaft 163 functions as a reorientation shaft, which causes the strap 140 extending from the first grip 150 to be realigned towards the first grip 150. The shaft 163 of the second grip 160 wraps the strap 140 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 to the first grip 150 is the strap 140 extending between the first grip 150 and the second grip 160. Overlaid on the portions, the two portions are then combined with each other using a buckle-shaped connecting 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 arranged on the first grip portion 150 and the second grip portion 160, respectively, so that the supports 150a and 160a can pivot in the direction of the upper longitudinal portion 110. The supports 150a and 160a are in the shape of bars. The hooks 111 arranged at both ends of the upper longitudinal direction portion 110 can be arranged on the supports 150a and 160a. Further, the distal ends of the supports 150a and 160a may be in the shape of an upward hook, thereby preventing the hook 111 disposed on it from slipping down.
