[0004] [Patent Literature]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2007-22660 Summary of the Invention

[0006] [The problem the invention aims to solve]

[0007] However, when installing the L-shaped strapping components at the four corners of a glass panel, it is impossible to install the strapping components on multiple glass panels without securing the strapping components themselves. Furthermore, if the L-shaped components move during the insertion of the glass panels, there is a risk that the glass panels may detach and break.

[0008] The present invention was made in view of the problems described above, and its objective is to provide a bundling clamp and a method for manufacturing a glass plate bundling body using the bundling clamp, wherein the bundling clamp can fix an L-shaped component and a binding component for bundling when the glass plate is inserted.

[0009] [Technical means to solve the problem]

[0010] The problem to be solved by the present invention is as described above, and the means for solving the problem will be described below.

[0011] That is, the bundling clamp according to Embodiment 1 of the present invention is a bundling clamp used when bundling multiple glass plates in a longitudinally placed and spaced parallel arrangement by a bundling member. The glass plates are rectangular in shape, and the bundling member includes: corner retaining members with corner retaining grooves forming four corners of the glass plate respectively; and a bundling member installed in a state surrounding the corner retaining members. The corner retaining members include: two lower corner retaining members that retain two lower corners of the glass plate respectively; and one or two upper corner retaining members that retain two upper corners of the glass plate. The bundling clamp includes a base member that retains the lower corner retaining members. The base member includes: a bottom retaining part that retains the bottom surface of the lower corner retaining members; and a limiting part that limits the position of the two lower corner retaining members in the width direction of the glass plate.

[0012] By incorporating this structure, the bundling clamp according to the present invention can perform bundling while the lower corner retaining member is held by the base member, thus preventing the lower corner retaining member from moving during the insertion of the glass plate and causing the glass plate to break.

[0013] Furthermore, in Embodiment 1, the binding clamp according to Embodiment 2 of the present invention preferably includes the following limiting part: a first limiting part that holds the side of one of the lower corner holding members; and a second limiting part that holds the side of the other lower corner holding member, wherein the distance between the first limiting part and the second limiting part can be changed.

[0014] By incorporating this structure, the distance between the two lower corner retaining members can be changed by altering the distance between the restricting parts. Therefore, even if the size of the glass plate is changed, the same bundling clamp can be used for bundling operations.

[0015] Furthermore, in Embodiment 3 of the present invention, the binding clamp for bundling is preferably provided in Embodiment 1 or 2, wherein the bottom retaining portion includes a bundling member receiving groove for receiving the bundling member.

[0016] By incorporating this structure, and by pre-accommodating the binding member in the groove of the bottom retaining part, the corner of the glass plate can be quickly secured using the binding member after the corner retaining member has held the corner of the glass plate in its current state.

[0017] Furthermore, in any of the embodiments 1 to 3, the bundling clamp according to Embodiment 4 of the present invention preferably further includes a guide member, the guide member having a side retaining groove for retaining the sides of the plurality of glass plates, and the guide member being mounted on the limiting portion.

[0018] By incorporating such a structure, and by including a guide member that holds the sides of the glass plate, it is possible to prevent the inserted glass plate from flexing and contacting adjacent glass plates, thus preventing damage.

[0019] Furthermore, in the embodiment 5 of the present invention, the packaging clamp in the embodiment 4 preferably has a mark formed on one of the upper corners of a plurality of glass plates, and the guide member includes: a first guide member that holds the side corresponding to the upper corner where the mark is provided; and a second guide member that holds the side corresponding to the other upper corner, wherein the first guide member is configured to fold its upper end back in a direction away from the side.

[0020] With this structure, the markings on the glass plate are formed to ensure the glass plate is oriented in the same direction. By bending the upper end of the guide member outward, the markings can be exposed even when the markings on the glass plate are housed within the groove of the guide member, thus confirming the alignment of the glass plate.

[0021] Furthermore, in Embodiment 4, the bundling clamp according to Embodiment 6 of the present invention preferably has the upper end of the guide member at the same height as the upper end of the glass plate, or higher than the upper end of the glass plate.

[0022] By incorporating this structure, when inserting a glass plate, it can be inserted without touching an already inserted glass plate, thus preventing the two from coming into contact and causing scratches.

[0023] Furthermore, the manufacturing method of the glass plate bundle according to Embodiment 7 of the present invention uses the bundling clamp of any of the embodiments of Embodiments 1 to 6 to bundle the glass plates in a longitudinally placed parallel arrangement with intervals, and the bundling member is used to bundle the glass plates. The method includes: a bundling member placement step, in which the bundling member is placed on the bottom holding portion; a lower corner holding member placement step, in which the lower corner holding member is placed on the bottom holding portion via the bundling member; a glass plate insertion step, in which the glass plate is inserted into the corner holding groove and held by the lower corner holding member; an upper corner holding step, in which the upper corner of the glass plate is held by the upper corner holding member; and a bundling step, in which the corner holding member is fixed by the bundling member.

[0024] By incorporating this structure, according to the manufacturing method of the glass plate bundle using the bundling clamp of the present invention, bundling can be performed while the lower corner retaining member is held by the base member, thus preventing the glass plate from breaking.

[0025] Furthermore, in Embodiment 7, the manufacturing method of the glass plate bundle according to Embodiment 8 of the present invention preferably further includes a guide member in the bundle clamp, the guide member having a side retaining groove for retaining the sides of a plurality of glass plates, and the manufacturing method further includes: a guide member installation step, in which the guide member is installed on the limiting part before the glass plate insertion step; and a guide member removal step, in which the guide member is removed from the limiting part after the glass plate insertion step, and the glass plate is inserted along the side retaining groove in the glass plate insertion step, the guide member removal step including: a first guide member removal step, in which one of the guide members is removed; and a second guide member removal step, in which another guide member is removed, the upper corner retaining step including: a first upper corner retaining step, in which the corner retaining member corresponding to the guide member removed in the first guide member removal step is installed after the first guide member removal step and before the second guide member removal step; and a second upper corner retaining step, in which the upper corner retaining member corresponding to the guide member removed in the second guide member removal step is installed after the second guide member removal step.

[0026] By incorporating this structure, and by disassembling the guide members one by one and installing the upper corner retaining members, it is possible to prevent the upper part of the glass plate from flexing and contacting adjacent glass plates, thus preventing scratches from forming on the glass plates.

[0027] Furthermore, in the glass plate bundle manufacturing method according to Embodiment 9 of the present invention, in Embodiment 7 or 8, the bundle clamp preferably further includes a guide member, the guide member having a side retaining groove for retaining the sides of a plurality of glass plates, and a mark being formed on one of the upper corners of the plurality of glass plates. The guide member includes: a first guide member for retaining the side corresponding to the upper corner where the mark is provided; and a second guide member for retaining the side corresponding to another upper corner. The first guide member is configured to fold its upper end back away from the side. The manufacturing method further includes: a guide member installation step, in which the guide member is installed on the limiting part before the glass plate insertion step; and a mark confirmation step, in which the guide member is installed on the limiting part before the glass plate insertion step. Then, the upper end of the first guide member is folded back in a direction away from the side, and the mark provided at the upper corner is confirmed; and a guide member disassembly process is performed after the mark confirmation process, in which the guide member is disassembled from the restricting part, the guide member disassembly process includes: a first guide member disassembly process, disassembling the first guide member; and a second guide member disassembly process, disassembling the second guide member, the upper corner holding process includes: a first upper corner holding process, holding the upper corner with the mark provided by the corner holding member; and a second upper corner holding process, holding the upper corner without the mark provided by the upper corner holding member, the first upper corner holding process is performed after the first guide member disassembly process and before the second guide member disassembly process.

[0028] With this structure, the markings on the glass plate are designed to ensure the glass plate is aligned. By bending the upper end of the guide member outward, the markings can be exposed even when they are stored within the groove of the guide member, thus confirming the alignment of the glass plate. Furthermore, the disassembly operation can proceed directly without restoring the upper part of the guide member that was bent down to confirm the markings, improving workability.

[0029] [The effects of the invention]

[0030] As a result of the invention, the following effects are achieved.

[0031] That is, according to the bundling clamp and the manufacturing method of the glass plate bundling body using the bundling clamp of the present invention, the L-shaped component and the bundling component for bundling can be fixed when the glass plate is inserted, and the glass plate can be prevented from breaking.

[0070] Next, use Figures 1 to 9 (A) ~ Figure 9 (F) describes one embodiment of the present invention.

[0071] In addition, Figure 1 The direction of the glass plate bundle 1 is indicated by arrows, specifying its front-back, left-right, and up-down directions. Furthermore, in... Figures 2 to 8 The arrows in the diagram indicate the front-back, left-right, and up-down directions of the glass plate bundle 1, the bundle component 2, and the bundle clamp 20.

[0072] [Overall structure of glass plate bundle 1]

[0073] First, use Figure 1 The overall structure of the glass plate bundle 1 formed by bundling using the bundling clamp 20 embodying the present invention will be described.

[0074] The glass plate bundle 1 is formed by bundling a glass plate G, which is an example of a glass product, with bundle members 2. The glass plate G is a plate-shaped component used as a glass substrate or cover glass for a display, a core substrate or interlayer for an encapsulation substrate, or a cover glass for a solar cell, and is configured in a rectangular shape.

[0075] The bundling member 2 includes: a corner retaining member 11, which has corner retaining grooves 11a formed for retaining the four corners Ga of the glass plate G respectively (see reference). Figure 7 ); and the binding member 12, which is installed while the corner retaining member 11 is surrounded.

[0076] The corner retaining member 11 includes: a lower corner retaining member 11L, which retains the two lower corners Ga of the glass plate G; and an upper corner retaining member 11U, which retains the two upper corners Ga of the glass plate G.

[0077] The lower corner retaining member 11L and the upper corner retaining member 11U are L-shaped when viewed from the front, and are formed at right angles with the four corners Ga of the glass plate G. For example... Figure 7 As shown, a plurality of corner retaining grooves 11a are formed on the inner side of the lower corner retaining member 11L and the upper corner retaining member 11U. Multiple corner retaining grooves 11a are provided in the front-rear direction, and the thickness of each groove in the front-rear direction is adapted to the thickness of the glass plate G.

[0078] The corner retaining member 11 is formed of foamed resin such as expanded polyethylene or expanded polystyrene. Therefore, even if the glass sheet bundle is subjected to vibration or impact during transportation or storage, the vibration or impact is difficult to be transmitted to the glass sheet, thus preventing the glass sheet from breaking.

[0079] The binding member 12 is formed from resin such as nylon, using a raw material with excellent durability and flexibility. Multiple binding members 12 are used, and they are used to bind the glass plates G in parallel in the front-to-back direction. Multiple binding members 12 are wound around the outer periphery of the lower corner retaining member 11L and the upper corner retaining member 11U. By attaching one end of the binding member 12 to the other end, the lower corner retaining member 11L and the upper corner retaining member 11U, located at the four corners Ga of the glass plate G, are fixed, thereby binding the multiple glass plates G in a non-movable manner.

[0080] A groove can be formed on the outer peripheral surface of the corner retaining member 11 to accommodate and guide the binding member 12.

[0081] [Overall structure of the bundling clamp 20]

[0082] Next, use Figures 2 to 8 The description of the bundling clamp 20 is as follows.

[0083] The bundling clamp 20 is a device used to bundle multiple glass plates G in a longitudinal position with intervals between them by means of the bundling member 2.

[0084] like Figure 2 and Figure 6 As shown, the packaging clamp 20 includes: a base member 21, a lower corner retaining member 11L; a guide member 22, having a side retaining groove 22a formed for retaining the side edges Gb of a plurality of glass plates G; and a frame 23 for fixing the base member 21 and the guide member 22.

[0085] like Figures 2 to 4 As shown, the base member 21 includes: a bottom retaining portion 26 that retains the bottom surface of the lower corner retaining member 11L; and a side retaining portion 27, which is an example of a limiting portion that retains the sides of the two lower corner retaining members 11L and is equipped with guide members 22. The bottom retaining portion 26 is a platform placed on the ground and is provided at the lower end of the frame 23. A plurality of holes (not shown) are provided on the upper surface of the bottom retaining portion 26, and by inserting fixing members into the holes, the side retaining portions 27 can be fixed relative to the bottom retaining portion 26.

[0086] Furthermore, a strapping member receiving groove 26a for accommodating the strapping member 12 is formed on the upper surface of the bottom retaining portion 26. In this embodiment, there are two strapping member receiving grooves 26a, but there may also be one or more.

[0087] The side retaining part 27 is a limiting part that restricts the position of the two lower corner retaining members 11L, 11L in the width direction of the glass plate G. It is an L-shaped member when viewed from the front, including a fixing part 27a fixed to the bottom retaining part 26, and two plate-shaped side abutting parts 27b that are erected vertically upward from the fixing part 27a.

[0088] In addition, the side retaining portion 27 includes: a first side retaining portion 27A, which retains the side of one of the lower corner retaining members 11L; and a second side retaining portion 27B, which retains the side of the other lower corner retaining member 11L.

[0089] The distance between the first side retaining portion 27A and the second side retaining portion 27B can be changed. For example, by removing the fixing member from the multiple holes provided in the bottom retaining portion 26 and moving the first side retaining portion 27A, the distance between the first side retaining portion 27A and the second side retaining portion 27B can be changed.

[0090] [Method for manufacturing glass plate bundle 1 using bundle clamp 20]

[0091] Next, use Figure 5 (A) ~ Figure 5(D) A method for manufacturing a glass plate bundle 1, in which multiple glass plates G are arranged in a longitudinal position and spaced apart, and then bundled by the bundling member 2 using a bundling clamp 20, will be described. Furthermore, in Figure 5 (A) ~ Figure 5 (D) Figure 9 (A) ~ Figure 9 (F) and Figure 10 (A) ~ Figure 10 In (H), the illustration of frame 23 is omitted.

[0092] First, a base member 21 is pre-positioned on the frame 23. By changing the fixed position of the first side holding part 27A in the frame 23, a pair of side holding parts 27A and 27B can be configured to match the length (width) of the glass plate G in the left and right directions.

[0093] Next, as Figure 5 As shown in (A), the binding member placement process S10 is performed, in which the binding member 12 is placed in the binding member receiving groove 26a provided in the bottom holding part 26. Two binding members 12 are arranged in parallel in the binding member receiving groove 26a provided in the bottom holding part 26.

[0094] Next, as Figure 5 As shown in (B), the lower corner retaining member placement step S20 is performed, in which the lower corner retaining member 11L is placed on the bottom retaining part 26 via the binding member 12. The lower corner retaining member 11L is disposed on the upper surface of the bottom retaining part 26, and the vertically arranged portion of the lower corner retaining member 11L is restricted from movement by the side abutment portions 27b of the first side retaining part 27A and the second side retaining part 27B.

[0095] Next, as Figure 5 As shown in (C), the glass plate insertion process S40 involves inserting the glass plate G into the corner retaining groove 11a and holding it by the lower corner retaining member 11L, and the upper corner retaining process S50 involves holding the upper corner Ga of the glass plate G by the upper corner retaining member 11U. In the upper corner retaining process S50, after installing one of the upper corner retaining members 11U, the other upper corner retaining member 11U is installed. That is, after fixing one corner Ga and its surrounding side and top edge by clamping it in the corner retaining groove 11a, the other upper corner Ga of the glass plate G and its surrounding side and top edge are fixed by clamping it in the corner retaining groove 11a.

[0096] Next, as Figure 5As shown in (D), the binding process S70, in which the lower corner retaining member 11L and the upper corner retaining member 11U are fixed by the binding member 12, is performed. That is, the binding member 12, which is disposed in the binding member receiving groove 26a provided in the bottom retaining part 26, is wrapped around the lower corner retaining member 11L, the lower corner retaining member 11L, the upper corner retaining member 11U, and the upper corner retaining member 11U, and the two ends are glued, thereby fixing the lower corner retaining member 11L and the upper corner retaining member 11U.

[0097] [Structure of guide component 22]

[0098] like Figures 6 to 8 As shown, the guide member 22 is a rectangular plate with side retaining grooves 22a. The side retaining grooves 22a have the same number as the corner retaining grooves 11a and are arranged in the front-rear direction at positions corresponding to the corner retaining grooves 11a. Furthermore, a connecting portion 22b is provided at the lower end of the guide member 22 for connecting to the upper end of the side retaining portion 27. The connecting portion 22b has a groove with the same width as the plate thickness of the side abutment portion 27b of the side retaining portion 27. By fitting the groove into the upper end of the side abutment portion 27b, the guide member 22 can be connected to the side retaining portion 27.

[0099] The guide member 22 includes a first guide member 22A connected to the upper end of the first side retaining portion 27A, and a second guide member 22B connected to the upper end of the second side retaining portion 27B.

[0100] [Method for manufacturing a glass plate bundle 1 using a bundling clamp 20 including a guide member 22]

[0101] Next, use Figure 9 (A) ~ Figure 9 (F) describes a method for manufacturing a glass plate bundle 1 that uses a bundling clamp 20 to bundle multiple glass plates G in a longitudinal position with spacing between them, and then uses the bundling member 2 to bundle them.

[0102] First, a base member 21 is pre-positioned on the frame 23. By changing the fixed position of the first side holding part 27A in the frame 23, a pair of side holding parts 27A and 27B can be configured to match the length of the glass plate G in the left and right directions.

[0103] Next, as Figure 9 As shown in (A), the binding member placement process S10 is performed, in which the binding member 12 is placed in the binding member receiving groove 26a provided in the bottom holding part 26. Two binding members 12 are arranged in parallel in the binding member receiving groove 26a provided in the bottom holding part 26.

[0104] Next, as Figure 9As shown in (B), the lower corner retaining member placement step S20 is performed, in which the lower corner retaining member 11L is placed on the bottom retaining part 26 via the binding member 12. The lower corner retaining member 11L is disposed on the upper surface of the bottom retaining part, and the vertically arranged portion of the lower corner retaining member 11L is restricted from movement by the side abutment portions 27b of the first side retaining part 27A and the second side retaining part 27B.

[0105] Next, as Figure 9 As shown in (C), the guide member installation step S30 is performed, in which the guide member 22 is installed on the first side holding portion 27A and the second side holding portion 27B. By fitting the connecting portion 22b at the lower end of the guide member 22 into the upper end of the side abutment portion 27b, the guide member 22 can be connected to the first side holding portion 27A and the second side holding portion 27B.

[0106] Next, as Figure 9 As shown in (D), the glass plate insertion process S40 is performed, in which the glass plate G is held by the lower corner retaining member 11L along the side retaining groove 22a of the guide member 22. The glass plate G is inserted downward from above the guide member 22 along the side retaining groove of the guide member 22, and is held by the lower corner retaining member 11L while being clamped in the corner retaining groove 11a provided by the lower corner retaining member 11L.

[0107] At this time, the upper end of the guide member 22 is at the same height as the upper end of the glass plate G. Alternatively, the upper end of the guide member 22 may be higher than the upper end of the glass plate G. With this configuration, the upper end of the glass plate G will not protrude from the guide member 22, and when inserting the glass plate G, it can be inserted without contacting the already inserted glass plate G, thus preventing scratches.

[0108] When the glass plate G is inserted into the corner retaining member 11L and the corner retaining groove 11a provided in the corner retaining member 11L, the side retaining part 27 holds the corner retaining member 11L and the corner retaining member 11L, which can restrict the movement of the corner retaining member 11L and the corner retaining member 11L, and the glass plate G is securely clamped in the corner retaining groove 11a.

[0109] Next, as Figure 9 As shown in (E), the process of removing the guide member 22 from the first side holding part 27A and the second side holding part 27B, and the process of holding the upper corner part Ga of the glass plate G by the upper corner part holding member 11U (S50) are performed.

[0110] The guide disassembly process and the upper corner retention process S50 are carried out according to the following steps.

[0111] First, the first guide member disassembly step S52 is performed to disassemble one of the guide members 22A.

[0112] Next, a first upper corner holding step S53 is performed, which involves installing the upper corner holding member 11U corresponding to the guide member 22 that was removed in the first guide member removal step S52. That is, one of the corner portions Ga and its surrounding side and top edges are clamped in the corner holding groove 11a for fixation. Thus, one of the upper corner portions Ga of the glass plate G is fixed by the upper corner holding member 11U.

[0113] Next, the second guide removal process S54, which involves removing another guide member 22, is performed.

[0114] Next, after the second guide member removal step S54, a second upper corner holding step S55 is performed to install the upper corner holding member 11U corresponding to the guide member 22 removed in the second guide member removal step S54. That is, the other corner Ga and its surrounding side and top edges are clamped in the corner holding groove 11a for fixation. Thus, the other upper corner Ga of the glass plate G is fixed by the upper corner holding member 11U.

[0115] Next, as Figure 9 As shown in (F), the binding process S70, in which the lower corner retaining member 11L and the upper corner retaining member 11U are fixed by the binding member 12, is performed. That is, the binding member 12, which is disposed in the binding member receiving groove 26a provided in the bottom retaining part 26, is wrapped around the lower corner retaining member 11L, the lower corner retaining member 11L, the upper corner retaining member 11U, and the upper corner retaining member 11U, and the two ends are glued, thereby fixing the lower corner retaining member 11L and the upper corner retaining member 11U.

[0116] By performing steps S10 to S70, the glass plate bundle 1 can be manufactured. By bundling the glass plate G while its sides are held in place by the side holding groove 22a of the guide member 22, the glass plate G will not fall over during the bundling operation, allowing for stable bundling. Furthermore, by changing the distance between the side holding portions 27A and 27B, the distance between the lower corner holding members 11L and 11B can be changed. Therefore, even if the size of the glass plate G is changed, the same bundling clamp 20 can be used for bundling operations.

[0117] Furthermore, as another embodiment, the structure of providing a marking portion on a part of the glass plate G will be described. Here, descriptions of structures common to the previously described embodiments are omitted. In this embodiment, a notch Gd serving as a marking is formed at one of the upper corners Ga of the glass plate G. That is, the operator can determine the top and bottom of the glass plate G based on the presence or absence of the notch Gd. Furthermore, when forming the marking on the glass plate G, perforations, printed markings, or stickers may also be formed.

[0118] [Overall structure of glass plate bundle 1]

[0119] First, use Figure 1 The overall structure of the glass plate bundle 1 formed by bundling using the bundling clamp 20 embodying the present invention will be described.

[0120] The glass plate bundle 1 is formed by bundling a glass plate G, which is an example of a glass product, with a bundling member 2. The glass plate G is rectangular in shape and has a notch Gd at the upper corner Ga. The notch Gd is, for example, formed by cutting the corner Ga along a straight line at a 45-degree angle. In addition, the width length of the notch Gd is less than 5% of the width length of the glass plate G.

[0121] The corner retaining member 11 includes: a lower corner retaining member 11L, which retains the two lower corners Ga of the glass plate G; and an upper corner retaining member 11U, which retains the two upper corners Ga of the glass plate G.

[0122] The lower corner retaining member 11L and the upper corner retaining member 11U are L-shaped when viewed from the front, and are formed at right angles with the four corners Ga of the glass plate G. The corner retaining member 11 in the part of the glass plate G where the cutout Gd is provided retains the upper and side edges that are continuous with the cutout Gd.

[0123] [Structure of the guiding component]

[0124] like Figure 10 (C) to Figure 10 As shown in (E), the first guide member 22A has an upper end portion 22c and a lower end portion 22d, and is configured to fold the upper end portion 22c back in a direction away from the side edge Gb. That is, the upper end portion 22c and the lower end portion 22d are connected by a connecting portion 22e made of a hinge. The connecting portion 22e is normally fixed so that the upper end portion 22c is positioned above the lower end portion 22d and forms a plate-like state. When folding back, the upper end portion 22c folds back via the connecting portion 22e.

[0125] [Method for manufacturing glass plate bundle 1 using bundle clamp 20]

[0126] Next, use Figure 10 (A) ~ Figure 10 (H) describes a method for manufacturing a glass plate bundle 1 that uses a bundling clamp 20 to bundle multiple glass plates G in a longitudinal position with intervals between them, and then uses a bundling member 2 to bundle them.

[0127] First, a base member 21 is pre-positioned on the frame 23. By changing the fixed position of the first side holding part 27A in the frame 23, a pair of side holding parts 27A and 27B can be configured to match the length of the glass plate G in the left and right directions.

[0128] Next, as Figure 10 As shown in (A), the binding member placement process S10 is performed, in which the binding member 12 is placed in the binding member receiving groove 26a provided in the bottom holding part 26. Two binding members 12 are arranged in parallel in the binding member receiving groove 26a provided in the bottom holding part 26.

[0129] Next, as Figure 10 As shown in (B), the lower corner retaining member placement step S20 is performed, in which the lower corner retaining member 11L is placed on the bottom retaining part 26 via the binding member 12. The lower corner retaining member 11L is disposed on the upper surface of the bottom retaining part 26, and the vertically arranged portion of the lower corner retaining member 11L is restricted from movement by the side retaining part 27A and the side abutment part 27b of the side retaining part 27A.

[0130] Next, as Figure 10 As shown in (C), the guide member installation step S30 is performed, in which the guide member 22 is installed on the first side holding portion 27A and the second side holding portion 27B. By fitting the connecting portion 22b at the lower end of the guide member 22 into the upper end of the side abutment portion 27b, the guide member 22 can be connected to the first side holding portion 27A and the second side holding portion 27B.

[0131] Next, as Figure 10As shown in (D), the glass plate insertion process S40 is performed, in which the glass plate G is held by the lower corner retaining member 11L along the side retaining groove 22a of the guide member 22. The glass plate G is inserted downward from above the guide member along the side retaining groove 22a of the guide member 22, and is held by the lower corner retaining member 11L while being clamped in the corner retaining groove 11a provided by the lower corner retaining member 11L. When the glass plate G is inserted into the corner retaining groove 11a provided by the lower corner retaining member 11L, the lower corner retaining member 11L is held by the side retaining part 27, which restricts the movement of the lower corner retaining member 11L, and the glass plate G is securely clamped in the corner retaining groove 11a.

[0132] Next, the guide member removal process is performed to remove the guide member 22 from the first side holding part 27A and the second side holding part 27B, and the upper corner holding process is performed to hold the upper corner part Ga of the glass plate G by the upper corner holding member 11U (S50).

[0133] The steps for disassembling the guide and retaining the upper corner are as follows.

[0134] First, such as Figure 10 As shown in (E), a cut confirmation process (marking confirmation process) is performed, in which the upper end of the first guide member 22A is folded back in a direction away from the side Gb, and the cut Gd provided at the upper corner Ga is confirmed. That is, the upper end 22c of the first guide member 22A is folded back in a direction away from the side Gb, so that the cut Gd is in a visible state. With the cut Gd present, it can be determined that the position of the glass plate G when it is bundled is normal.

[0135] Next, as Figure 10 As shown in (F), the first guide member disassembly step S52 is performed to disassemble one of the guide members 22A.

[0136] Next, a first upper corner holding step S53 is performed, which involves installing the upper corner holding member 11U corresponding to the guide member 22 that was removed in the first guide member removal step S52. That is, one of the corner portions Ga and its surrounding side and top edges are clamped in the corner holding groove 11a for fixation. Thus, one of the upper corner portions Ga of the glass plate G is fixed by the upper corner holding member 11U.

[0137] Next, as Figure 10 As shown in (G), the second guide removal step S54 is performed to remove another guide member 22.

[0138] Next, after the second guide member removal step S54, a second upper corner holding step S55 is performed to install the upper corner holding member 11U corresponding to the guide member 22 removed in the second guide member removal step S54. That is, the other corner Ga and its surrounding side and top edges are clamped in the corner holding groove 11a for fixation. Thus, the other upper corner Ga of the glass plate G is fixed by the upper corner holding member 11U.

[0139] Next, as Figure 10 As shown in (H), the binding process S70, in which the lower corner retaining member 11L and the upper corner retaining member 11U are fixed by the binding member 12, is performed. That is, the binding member 12, which is disposed in the binding member receiving groove 26a provided in the bottom retaining part 26, is wrapped around the lower corner retaining member 11L, the lower corner retaining member 11L, the upper corner retaining member 11U, and the upper corner retaining member 11U, and the two ends are glued, thereby fixing the lower corner retaining member 11L and the upper corner retaining member 11U.

[0140] By performing steps S10 to S70, the glass plate bundle 1 can be manufactured. By bundling the glass plate G while its sides are held in place by the side holding groove 22a of the guide member 22, the glass plate G will not fall over during the bundling operation, allowing for stable bundling. Furthermore, by changing the distance between the side holding portions 27A and 27B, the distance between the lower corner holding members 11L and 11B can be changed. Therefore, even if the size of the glass plate G is changed, the same bundling clamp 20 can be used for bundling operations.

[0141] As described above, the bundling clamp 20 of the present invention is used to bundle multiple glass plates G in a longitudinally placed and spaced parallel arrangement by a bundling member 2. The glass plates G are rectangular in shape. The bundling member 2 includes: a lower corner retaining member 11L and an upper corner retaining member 11U, forming corner retaining grooves 11a that respectively retain the four corners Ga of the glass plate G; and a bundling member 12, which is installed in a state of surrounding the lower corner retaining member 11L and the upper corner retaining member 11U. The bundling clamp 20 includes a base member 21 that retains the lower corner retaining member 11L. The base member 21 includes: a bottom retaining part 26 that retains the bottom surface of the lower corner retaining member 11L; and a side retaining part 27 that is a limiting part that restricts the position of the two lower corner retaining members 11L, 11L in the width direction of the glass plate G.

[0142] With this configuration, the glass plate G can be bundled while the lower corner retaining member 11L is held in place by the base member 21, thus preventing the glass plate G from breaking.

[0143] Furthermore, it is preferable to include: a first side holding portion 27A, which holds the side of one of the lower corner holding members 11L; and a second side holding portion 27B, which holds the side of the other lower corner holding member 11L, wherein the distance between the first side holding portion 27A and the second side holding portion 27B can be changed.

[0144] With this configuration, the distance between the side retaining parts 27A and 27B can be changed, as can the distance between the lower corner retaining members 11L and 11B. Therefore, even if the size of the glass plate G is changed, the same bundling clamp 20 can be used for bundling operations.

[0145] Furthermore, the bottom retaining portion 26 preferably includes a binding member receiving groove 26a for receiving the binding member 12.

[0146] With this configuration, by pre-accommodating the binding member 12 in the binding member receiving groove 26a of the bottom holding part 26, the corner Ga of the glass plate G can be quickly fixed using the binding member 12 after the corner holding member 11L and the upper corner holding member 11U hold the corner Ga of the glass plate G.

[0147] Furthermore, the preferred packaging clamp 20 also includes a guide member 22, which has a side retaining groove 22a for retaining the side edges Gb of the plurality of glass plates G, and the guide member 22 is mounted on the side retaining portion 27.

[0148] With this configuration, by including the guide member 22 that holds the side edge Gb of the glass plate G, it is possible to prevent the inserted glass plate G from flexing and coming into contact with the glass plate and forming a scratch.

[0149] Furthermore, it is preferable that a notch Gd is formed in one of the upper corners Ga of the plurality of glass plates G, and the guide member 22 includes: a first guide member 22A, which holds the side edge Gb corresponding to the upper corner Ga where the notch Gd is provided; and a second guide member 22B, which holds the side edge Gb corresponding to the other upper corner Ga. The first guide member 22A is configured to be able to fold the upper end 22c back in a direction away from the side edge Gb.

[0150] With this configuration, the cut Gd provided in the glass plate G is formed to ensure that the glass plate G is oriented in the same direction. By bending the upper end 22c of the guide member 22 outward, even when the cut Gd provided in the glass plate G is housed in the side retaining groove 22a of the guide member 22, the cut Gd can be exposed, thus confirming that the glass plate G is oriented in the same direction.

[0151] Furthermore, it is preferable that the upper end of the guide member 22 is at the same height as the upper end of the glass plate G, or is higher than the upper end of the glass plate G.

[0152] With this configuration, when inserting the glass plate G, it can be inserted without touching the already inserted glass plate G, thus preventing the formation of scratches.

[0153] Furthermore, the preferred method for manufacturing the glass plate bundle 1 using the bundling clamp 20 of the present invention is a method for bundling a glass plate bundle 1 by means of a bundling member 2 in which a plurality of glass plates G are arranged in a longitudinal position with intervals. The method includes: a bundling member placement step S10, in which the bundling member 12 is placed on the bottom holding portion 26; and a lower corner holding member placement step S20, in which the lower corner holding member 11L is placed via the bundling member 12. Above the bottom holding part 26; glass plate insertion process S40, inserting the glass plate G into the corner holding groove 11a and holding it by the lower corner holding member 11L; upper corner holding process S50, holding the upper corner Ga of the glass plate G by the upper corner holding member 11U; and binding process S70, fixing the corner holding member 11L, corner holding member 11U, and corner holding member 11U with the binding member 12.

[0154] With this configuration, by using the side retaining groove 22a of the guide member 22A and guide member 22B to hold the side Gb of the glass plate G while bundling, the glass plate G will not fall over during the bundling operation, and bundling can be carried out in a stable state.

[0155] Furthermore, the preferred bundling clamp 20 also includes a guide member 22, which has a side retaining groove 22a for retaining the sides Gb of a plurality of glass plates G. The manufacturing method further includes: a guide member installation step S30, in which the guide member 22 is installed on the side retaining portion 27 before the glass plate insertion step S40; and a guide member removal step, in which the guide member 22 is removed from the side retaining portion 27 after the glass plate insertion step S40, and the glass plates G are inserted along the side retaining groove 22a in the glass plate insertion step S40. The guide member removal step includes: a first guide member removal step S52, in which the guide member 22 is removed from the side retaining portion 27. The process includes: removing one of the guide members 22A; and a second guide member removal process S54, removing the other guide member 22B. The upper corner holding process includes: a first upper corner holding process S53, after the first guide member removal process S52 and before the second guide member removal process S54, installing a corner holding member 11U corresponding to the guide member 22A removed in the first guide member removal process S52; and a second upper corner holding process S55, after the second guide member removal process S54, installing an upper corner holding member 11U corresponding to the guide member 22B removed in the second guide member removal process S54.

[0156] With this configuration, by disassembling the guide members 22A and 22B one by one and installing the upper corner retaining members 11U and 11U, it is possible to prevent the upper part of the glass plate G from bending and contacting the glass plate G, thus preventing scratches from forming on the glass plate G.

[0157] Furthermore, the preferred bundling clamp 20 also includes a guide member 22, which has a side retaining groove 22a for retaining the side edges Gb of a plurality of glass plates G. A cutout Gd is formed at one upper corner Ga of the plurality of glass plates G. The guide member 22 includes: a first guide member 22A for retaining the side edge Gb corresponding to the upper corner Ga with the cutout Gd; and a second guide member 22B for retaining the side edge Gb corresponding to the other upper corner Ga. The first guide member 22A is configured to fold its upper end 22c away from the side edge Gb. The manufacturing method further includes: a guide member installation step S30, where the guide member 22 is installed on the side retaining portion 27 before the glass plate insertion step S40; and a cutout confirmation step S51, where the upper end 22c of the first guide member 22A is folded back after the glass plate insertion step S40. The end 22c is folded back in a direction away from the side Gb, and the cut Gd provided at the upper corner Ga is confirmed; and the guide member disassembly process, after the cut confirmation process S51, the guide member 22 is disassembled from the side holding part 27. The guide member disassembly process includes: a first guide member disassembly process S52, disassembling the first guide member 22A; and a second guide member disassembly process S54, disassembling the second guide member 22B. The upper corner holding process includes: a first upper corner holding process S53, holding the upper corner Ga with the cut Gd provided by the corner holding member 11U; and a second upper corner holding process S55, holding the upper corner Ga without the cut Gd provided by the upper corner holding member 11U. The first upper corner holding process S53 is performed after the first guide member disassembly process S52 and before the second guide member disassembly process S54.

[0158] With this configuration, the cut Gd provided in the glass plate G is formed to ensure the orientation of the glass plate G is consistent. By bending the upper end 22c of the guide member 22 outward, even when the cut Gd provided in the glass plate G is contained within the side retaining groove 22a of the guide member 22, the cut can still be exposed, confirming the orientation of the glass plate G. Furthermore, the upper end 22c of the guide member 22, which was bent down to confirm the cut Gd, can be directly transferred to the disassembly operation without restoring it, improving workability.

[0159] The foregoing has described one embodiment of the present invention, but the present invention is by no means limited to this embodiment, which is merely an example. It can of course be implemented in a variety of ways without departing from the spirit of the present invention. The scope of the present invention is indicated by the claims, and also includes all modifications within the equivalent meaning and scope of the claims.
