Description

Technical Field

[0001] This utility model relates to a tray for bundling glass plates and a glass plate bundling body using the tray. Background Technology

[0002] Previously, there were known glass plate bundling trays for bundling, transporting or storing multiple manufactured glass plates together.

[0003] The aforementioned glass plate bundling tray mainly comprises a base portion and a support portion disposed on the upper part of the base portion. Multiple glass plates are placed on the support portion in a state of glass plate stacking formed by stacking each other, and are bundled by the glass plate bundling tray.

[0004] Here, during the transport of glass plate bundles constructed using this bundling method, there is a risk that unforeseen impacts or excessive vibrations from the outside could cause breakage or damage to the glass plates.

[0005] Therefore, as an example of a solution to the impact and vibration during such transportation, Patent Document 1 discloses a glass bundling tray (glass plate bundling tray) which includes: legs that protrude downward from the lower surface of the base; a cover member that covers the legs from below; and a sheet-like vibration damping member that is fixed to the cover member and sandwiched between the legs and the cover member.

[0009] The problem to be solved by utility models

[0010] However, in the glass plate bundling tray in Patent Document 1, a vibration damping member can be used to absorb impacts and vibrations applied along the thickness direction (i.e., the vertical direction) of the vibration damping member. However, since the position of the legs is restricted by the cover member, it is difficult to use the vibration damping member to absorb impacts and vibrations applied along the direction orthogonal to the thickness direction (i.e., the horizontal direction).

[0011] Therefore, the existing glass plate bundling pallets are not sufficiently vibration-resistant against impacts and vibrations applied in any direction, and glass plate bundling pallets with higher vibration-resistant performance are required.

[0012] This invention was made in view of the current problems mentioned above. The objective is to provide a glass plate bundling tray for bundling multiple glass plates in a stacked state, and a glass plate bundling body using the glass plate bundling tray. The glass plate bundling tray and the glass plate bundling body can provide sufficient vibration damping performance against the impact and vibration applied during transportation, making it difficult for the bundled glass plates to break or be damaged.

[0013] Solution for solving the problem

[0014] The problem to be solved by this utility model is as described above. The solution to solve this problem will be described below.

[0015] That is, the glass plate bundling tray of Scheme 1 of this utility model bundles multiple glass plates in a stacked state. The glass plate bundling tray is characterized by having: a base portion; and a support portion disposed above the base portion and supporting the loading posture of the glass plates. The base portion has: a base main body portion that supports the support portion; and multiple buffer members disposed below the base main body portion. The buffer members are composite members consisting of a rubber cover member and a compression helical spring with the axial direction set in the up-down direction.

[0016] With this structure, the glass plate bundling tray according to the present invention can absorb and buffer impacts and vibrations applied in the vertical direction by extending and contracting the compression helical spring that constitutes the buffer member in the axial direction. In addition, it can absorb and buffer impacts and vibrations applied in the horizontal direction by bending the compression helical spring in any direction.

[0017] Therefore, the buffer components can effectively buffer impacts and vibrations applied in any direction, and can provide sufficient vibration damping performance against impacts and vibrations applied during transportation.

[0018] Furthermore, the glass plate bundling tray of Scheme 2 of this utility model is characterized in that the cover component is composed of a hollow cylindrical component, based on Scheme 1 above.

[0019] With this structure, the glass plate bundling tray according to the present invention, for example, has a rubber cover member arranged in the up-down direction in the same way as a compression coil spring, so that the cover member can also effectively buffer impacts and vibrations applied in any direction, and can exert more effective vibration damping performance against impacts and vibrations applied during transportation.

[0020] Furthermore, the glass plate bundling tray of Scheme 3 of this utility model is based on Scheme 2 above, characterized in that the cover member is configured axially in the up-down direction, and the compression helical spring is embedded in the inner periphery of the cover member on the same axis as the cover member.

[0021] With this structure, the glass plate bundling tray according to the present invention can effectively buffer impacts and vibrations applied in any direction by using the cover member to protect the compression helical spring, while using the composite member of the cover member and the compression helical spring. It can exert a more sufficient anti-vibration performance against impacts and vibrations applied during transportation.

[0022] Furthermore, the glass plate bundling tray of Scheme 4 of this utility model is based on any one of Schemes 1 to 3 above, characterized in that the plurality of buffer members are arranged in an orthogonal direction orthogonal to the axial direction of the compression helical spring to form a buffer unit, and the buffer unit is provided in the base portion in a plurality of ways.

[0023] With this structure, the glass plate bundling tray according to the present invention, by bringing together multiple buffer members to form a buffer unit, can, for example, distribute and bear the compressive load applied to the buffer unit to each buffer member, suppress buckling generated in each buffer member, and prevent the rapid deterioration of the buffer member.

[0024] Furthermore, the glass plate bundling tray of Scheme 5 of this utility model is based on Scheme 4 above, characterized in that the plurality of buffer units are arranged at a position overlapping with the periphery of the main body of the base when viewed from above.

[0025] With this structure, the glass plate bundling tray according to the present invention has multiple buffer units arranged along the periphery of the base body on the lower side of the base body, which makes it easy to perform maintenance operations such as inspection and replacement of each buffer unit.

[0026] Furthermore, the glass plate bundling pallet of Scheme 6 of this utility model is characterized in that, based on Scheme 4 or Scheme 5 above, the glass plate bundling pallet utilizes the gap between a pair of adjacent buffer units on the side of the base portion to form an insertion port for inserting a forklift claw portion.

[0027] With this structure, the glass plate bundling pallet according to the present invention can be inserted into the forklift claw via the insertion port while avoiding collision with the buffer unit, and the glass plate bundling pallet can be easily transported by the forklift.

[0028] Furthermore, the glass plate bundling tray of Scheme 7 of this utility model is characterized in that, based on any one of Schemes 1 to 6 above, the composite spring constant of the plurality of buffer components, which combines the individual compression helical springs, is less than 5000 N / mm.

[0029] With this structure, the glass plate bundling tray according to the present invention can effectively buffer impacts and vibrations applied in any direction, even when multiple glass plates are bundled in a stacked state and are relatively heavy.

[0030] Furthermore, the glass plate bundling body of Scheme 8 of this utility model is characterized by comprising: a glass plate bundling tray as described in any one of Schemes 1 to 7 above; and a glass plate stack body, which is composed of multiple stacked glass plates and is placed on the base portion of the glass plate bundling tray.

[0031] With this structure, the glass plate bundle according to the present invention can absorb and buffer impacts and vibrations applied in the vertical direction by extending and contracting the compression helical spring that constitutes the buffer member in the axial direction. In addition, it can absorb and buffer impacts and vibrations applied in the horizontal direction by bending the compression helical spring in any direction.

[0032] Therefore, the buffer components can effectively buffer impacts and vibrations applied in any direction, and can provide sufficient vibration damping performance against impacts and vibrations applied during transportation.

[0054] It should be noted that, for convenience, the following explanation uses... Figures 1 to 3 The direction of the arrows shown indicates the front-back, left-right, and up-down directions of the glass plate bundling tray 1.

[0055] [The overall structure of the tray 1 for bundling glass plates]

[0056] First, use Figures 1 to 3 The overall structure of the glass plate bundling tray 1 (hereinafter referred to as tray 1) of this utility model will be described.

[0057] In this embodiment, the tray 1 is used in the manufacturing process of glass plates Ga, which are used as glass substrates or cover glass for panel displays such as liquid crystal display devices and organic EL display devices, to bundle, transport, or store multiple manufactured glass plates Ga in a stacked state.

[0058] It should be noted that the following description mainly focuses on the structure of the tray 1 that bundles multiple glass plates Ga in a longitudinal position, but is not limited to this.

[0059] That is, the tray 1 in this embodiment also includes a tray for bundling multiple glass plates Ga in a flat position (not shown).

[0060] like Figure 1 as well as Figure 2 As shown, tray 1 constructs a glass plate bundle M by tilting and placing a glass plate stack G composed of multiple stacked glass plates Ga in a longitudinal orientation.

[0061] Here, the glass plate Ga is a rectangular flat glass component with external dimensions (longitudinal dimension × transverse dimension) of (10000mm × 1200mm) or more and (2900mm × 3200mm) or less, and a plate thickness of 0.2mm or more and 2.0mm or less.

[0062] It should be noted that in the glass plate laminate G, a protective sheet (not shown) made of, for example, rectangular sheet-shaped pure pulp paper (backing paper), resin, etc., may also be sandwiched between a pair of adjacent glass plates Ga.

[0063] The tray 1 mainly includes a base 2 and a platform 3 disposed above the base 2.

[0064] It should be noted that the mounting platform 3 is an example of the support part of this utility model.

[0065] The base section 2 has a base frame 21 that constitutes a loading and unloading platform, a support frame 22 that supports the platform 3 from the base frame 21, and a base plate 23 located below the base frame 21.

[0066] In addition, the base portion 2 has a plurality of (10 in this embodiment) buffer devices 10 (more specifically, buffer units 13) clamped between the base frame 21 and the base plate 23.

[0067] It should be noted that the base frame 21 is an example of the base body of this utility model.

[0068] like Figure 3As shown, the base frame 21 has a frame portion 21a that is constructed of a rectangular frame when viewed from above, and a grid portion 21b that is horizontally mounted on the inner periphery of the frame portion 21a and is constructed of a lattice structure.

[0069] like Figure 2 As shown, the support frame 22 has, for example, a support along one end of the upper surface of the base frame 21 ( Figure 2 The front end of the support is provided with multiple support blocks 22a that support the support platform 3 (more specifically, the lower end support member 31 described later) and along the other end ( Figure 2 Multiple support pillars 22b are configured at the rear end and extend upwards.

[0070] Additionally, the support frame 22 has a back frame 22c arranged along the back 32b (rear surface) of the mounting platform 3 (more specifically, the back support member 32 described later) and formed by a lattice structure, and a plurality of beams 22d that connect the back frame 22c to the plurality of columns 22b.

[0071] That is, the platform 3 (lower end support member 31 and back support member 32) is fixedly supported on the base frame 21 via the support frame 22.

[0072] The base plate 23 is composed of a rectangular flat plate member with approximately the same external dimensions as the base frame 21, and as shown in the figure. Figure 3 As shown, it is configured to overlap with the base frame 21 when viewed from above.

[0073] Furthermore, the base frame 21 is fixedly supported on the upper surface of the base plate 23 by a plurality of buffer devices 10 (buffer units 13).

[0074] That is, multiple buffer units 13 are disposed on the lower side of the base frame 21.

[0075] Multiple buffer units 13 are arranged at predetermined intervals on the periphery of the base frame (base body) 21, i.e., at the position overlapping with the frame 21a, when viewed from above.

[0076] With this structure, according to the tray 1 in this embodiment, multiple buffer units 13 are arranged along the periphery of the base frame 21 on the lower side of the base frame (base body) 21, making it easy to perform maintenance operations such as inspection and replacement of each buffer unit 13.

[0077] Furthermore, among the plurality of buffer units 13, an insertion port Q is formed between adjacent pairs of buffer units 13, through which a forklift claw (not shown) can be inserted (see reference). Figure 1 as well as Figure 2 ).

[0078] In other words, such as Figure 1 as well as Figure 2 As shown, in the pallet 1 of this embodiment, an insertion port Q for inserting a forklift claw is formed on the side of the base portion 2 by utilizing the gap between a pair of adjacent buffer units 13.

[0079] With this structure, the pallet 1 according to this embodiment can be inserted into the forklift claw via the insertion port Q while avoiding collision with the buffer unit 13, and the pallet 1 can be easily transported using the forklift.

[0080] It should be noted that details regarding the structure of the buffer device 10 with buffer unit 13 will be described later.

[0081] The mounting stage 3 has a lower end face support member 31 that supports the lower end face of the glass plate laminate G in a longitudinal orientation, and a back face that supports the glass plate laminate G as one side of the plane (in Figure 2 The back support member 32 (with the rear surface in the middle).

[0082] The lower end face support member 31 is composed of components along the horizontal direction and in one direction (in Figure 1 It consists of a roughly rectangular strip-shaped component extending from the center (left to right), and is arranged so that the upper surface 31a is slightly inclined towards the front and upward.

[0083] Furthermore, the glass plate laminate G is placed on the upper surface 31a in a longitudinal orientation and its lower end face is supported by the lower end face support member 31.

[0084] The rear support member 32 is composed of a rectangular flat plate and supports one end of the lower end face of the support member 31 (in... Figure 2 (The middle part is the rear end) extends vertically upward.

[0085] That is, the lower end face of the support member 31 side of the back support member 32 (in Figure 2 The surface 32a (front side) functions as a support surface.

[0086] It should be noted that the external dimensions of surface 32a are set to be slightly larger than those of glass plate Ga.

[0087] Furthermore, the glass plate laminate G, which is placed vertically on the upper surface 31a of the lower end support member 31, is supported on the back side (rear surface) by the surface 32a of the back support member 32, thereby facing the back support member 32 side ( Figure 2 The rear side of the middle is slightly tilted.

[0088] That is, the mounting platform 3 supports the mounting posture of the multiple glass plates Ga bundled by the tray 1.

[0089] [Structure of buffer device 10]

[0090] Next, use Figure 4 The structure of the buffer device 10 will be described in detail.

[0091] The buffer device 10 mainly includes a base member 11, a leg member 12 located above the base member 11, and a buffer unit 13 sandwiched between the base member 11 and the leg member 12.

[0092] The base member 11 has, for example, a base plate portion 111 formed by a rectangular plate-shaped portion, and a first protrusion 112 and a second protrusion 113 protruding from a plane 111a on one side of the base plate portion 111.

[0093] In addition, the base member 11 is configured with the aforementioned plane 111a facing upwards.

[0094] The first protrusion 112 is composed of a generally hollow cylindrical portion and is provided in a state of protruding upward in the center of the substrate portion 111.

[0095] In addition, the inner periphery of the first protrusion 112 is composed of a first through hole 112a that extends in the vertical direction and a second through hole 112b that communicates with the lower end of the first through hole 112a and is coaxial with the first through hole 112a.

[0096] The first through hole 112a is formed by a cylindrical shape having an inner diameter that is slightly larger than the outer diameter of the screw portion 14a in the fastening member 14, which is used to fix the connecting pin 15 described later.

[0097] In addition, the second through hole 112b is formed by a cylindrical shape having an inner diameter that is slightly larger than the outer diameter of the head 14b in the fastening member 14.

[0098] That is, the inner diameter of the second through hole 112b is set to be larger than the inner diameter of the first through hole 112a, and a step portion 112c is formed between the first through hole 112a and the second through hole 112b.

[0099] On the other hand, a third through hole 111b communicating with the second through hole 112b is provided in the central part of the substrate portion 111, and the inner diameter of the third through hole 111b is set to be approximately the same as the inner diameter of the second through hole 112b.

[0100] Furthermore, as will be described later, when the connecting pin 15 is fixed to the first protrusion 112, the fastening member 14 that is screwed to the connecting pin 15 is inserted into the inner periphery of the first protrusion 112 from below the base plate portion 111 through the third through hole 111b with the screw portion 14a facing upward.

[0101] Thus, the head 14b of the fastening member 14 abuts against the step portion 112c, and the fastening member 14 is in a state of being engaged with the inner periphery of the first protrusion portion 112, and the connecting pin 15 is fixed to the first protrusion portion 112.

[0102] The second protrusion 113 is composed of a generally hollow cylindrical portion, the outer diameter of which is set to be approximately the same as the inner diameter of the compression coil spring 13a1 described later.

[0103] Furthermore, multiple second protrusions 113 are provided in a base member 11 (four in this embodiment), and each second protrusion 113 is arranged in an upward protruding state near, for example, a corner of the base plate portion 111. Figure 4 It is a sectional perspective view, therefore only the two second protrusions 113 are shown.

[0104] Furthermore, as will be described later, the second protrusion 113, together with the third protrusion 124 provided on the leg member 12, is inserted into the inner periphery of the compression coil spring 13a1.

[0105] The leg member 12 has: a top plate portion 121, which is formed, for example, a rectangular flat plate portion; a bottom plate portion 122, which is formed with a shape substantially the same as the top plate portion 121 and is arranged parallel to the top plate portion 121; a connecting portion 123, which is provided between the top plate portion 121 and the bottom plate portion 122 and connects the two members 121 and 122; and a third protrusion 124, which is provided on a plane 122a on the side of the bottom plate portion 122 opposite to the side of the top plate portion 121.

[0106] In addition, the leg member 12 is positioned above the base member 11 such that the plane 122a of the base plate portion 122 faces the plane 111a of the base plate portion 111.

[0107] It should be noted that the leg member 12 is fixedly mounted on the frame portion 21a via a plane 121a on the side of the top plate portion 121 opposite to the bottom plate portion 122 (see reference). Figure 3 The lower surface of ).

[0108] The third protrusion 124 is composed of a generally hollow cylindrical portion, the outer diameter of which is set to be slightly smaller than the inner diameter of the compression coil spring 13a1 described later.

[0109] In addition, multiple third protrusions 124 are provided in a leg member 12 (four in this embodiment), and each third protrusion 124 is provided, for example, near the corner of the base plate portion 122, in a downward protruding state. Figure 4This is a sectional perspective view, so only two third protrusions 124 are shown. That is, these third protrusions 124 are respectively arranged coaxially with respect to the plurality of second protrusions 113 in the base member 11.

[0110] Furthermore, as will be described later, the third protrusion 124, together with the second protrusion 113 provided on the base member 11, is inserted into the inner periphery of the compression coil spring 13a1.

[0111] A fourth through hole 122b is provided in the center of the base plate 122.

[0112] The fourth through hole 122b is coaxially disposed relative to the first protrusion 112 of the base member 11.

[0113] Here, the leg member 12 is connected to the base member 11 via the connecting pin 15, allowing it to move up and down.

[0114] The connecting pin 15 has a main body 15a consisting of a generally hollow cylindrical portion and a flange 15b at one axial end provided in the main body 15a. An internal thread 15a1 is provided on the inner circumferential surface of the main body 15a, which can be screwed into the screw portion 14a of the fastening member 14.

[0115] On the other hand, the inner diameter of the fourth through hole 122b is set to be slightly larger than the outer diameter of the main body 15a in the connecting pin 15, and smaller than the outer diameter of the flange 15b.

[0116] Furthermore, the connecting pin 15 is inserted into the fourth through hole 122b from above the base plate portion 122 with the flange portion 15b facing upward, and is screwed into the fastening member 14 inserted from below the base plate portion 111 into the inner periphery of the first protrusion portion 112.

[0117] Thus, the front end of the first protrusion 112 in the base member 11 of the connecting pin 15 is fixed coaxially with the first protrusion 112.

[0118] As a result, the leg member 12 can be connected to the base member 11 in a vertical direction via the fourth through hole 122b along the main body portion 15a of the connecting pin 15, and the base plate portion 122 is engaged with the flange portion 15b, thereby preventing it from falling off the base member 11.

[0119] The buffer unit 13 has a plurality of (four in this embodiment) buffer mechanism portions 13a and a fixing plate portion 13b that fixes the plurality of buffer mechanism portions 13a together. Figure 4 It is a sectional side view, so only the two buffer mechanism parts 13a are shown.

[0120] It should be noted that the buffer mechanism 13a is an example of the buffer component of this utility model.

[0121] The buffer mechanism 13a has a compression helical spring 13a1 and a cylindrical part 13a2 made of a hollow cylindrical rubber part.

[0122] It should be noted that the cylindrical part 13a2 is an example of the cover component of this utility model.

[0123] The inner diameter of the cylindrical portion 13a2 is set to be slightly larger than the outer diameter of the compression coil spring 13a1, and the compression coil spring 13a1 is embedded in the inner circumference of the cylindrical portion 13a2 on the same axis as the cylindrical portion 13a2.

[0124] That is, in this embodiment, the buffer mechanism 13a is a composite component consisting of a compression helical spring 13a1 and a cylindrical part 13a2.

[0125] Furthermore, the buffer mechanism 13a is configured such that the axial direction of the compression coil spring 13a1 (or the cylindrical part 13a2) is set to the up-down direction.

[0126] In addition, multiple buffer mechanism portions 13a are arranged in a position coaxial with the multiple second protrusions 113 in the base member 11 and the multiple third protrusions 124 in the leg member 12.

[0127] In other words, the multiple buffer mechanism parts 13a are arranged in an orthogonal direction that is orthogonal to the axis of the compression coil spring 13a1.

[0128] Furthermore, each buffer mechanism 13a is configured such that the second protrusion 113 is inserted into the lower end and the third protrusion 124 is inserted into the upper end in the inner circumference of the compression coil spring 13a1.

[0129] Thus, multiple buffer mechanism parts 13a are respectively clamped between the base member 11 and the leg member 12 in a state of being restricted to a predetermined configuration position via the second protrusion 113 and the third protrusion 124.

[0130] Furthermore, for example, when an unexpected impact or excessive vibration is applied to the buffer device 10 in the vertical direction, the compression coil spring 13a1 and the cylindrical part 13a2 of each buffer mechanism part 13a extend and retract along the axial direction, thereby forming a structure that effectively absorbs and buffers these impacts and vibrations using the buffer mechanism part 13a.

[0131] In addition, for example, when an unexpected impact or excessive vibration is applied to the buffer device 10 in the horizontal direction, the compression coil spring 13a1 and the cylindrical part 13a2 of each buffer mechanism part 13a bend in any direction relative to the axial direction, thereby making it a structure that effectively absorbs and buffers these impacts and vibrations by means of the buffer mechanism part 13a.

[0132] Thus, in the tray 1 of this embodiment, the cylindrical part (cover member) 13a2 becomes a structure composed of a hollow cylindrical member.

[0133] With this structure, according to the tray 1 in this embodiment, for example, a rubber cylindrical part (cover member) 13a2 is arranged in the up-down direction in the same way as the compression coil spring 13a1. Thus, the cylindrical part 13a2 can also be used to effectively buffer impacts, vibrations, etc. applied in any direction, and can exert more sufficient anti-vibration performance against impacts and vibrations applied during transportation.

[0134] In addition, in the tray 1 of this embodiment, the structure is as follows: the cylindrical part (cover member) 13a2 is arranged in the vertical direction, and the compression coil spring 13a1 is embedded in the inner periphery of the cylindrical part (cover member) 13a2 on the same axis as the cylindrical part (cover member) 13a2.

[0135] With this structure, the tray 1 according to this embodiment can effectively buffer impacts and vibrations applied in any direction by using the cylindrical part (cover member) 13a2 to protect the compression coil spring 13a1, while using the composite member of the cylindrical part (cover member) 13a2 and the compression coil spring 13a1, thus providing more adequate vibration damping performance against impacts and vibrations applied during transport.

[0136] The fixing plate portion 13b is composed of a roughly rectangular flat rubber section, and is arranged near the corners in such a way that the multiple buffer mechanism portions 13a are respectively orthogonal. That is, the multiple buffer mechanism portions 13a are interconnected via the fixing plate portion 13b.

[0137] In addition, a fifth through hole 13b1 is provided in the center of the fixed plate portion 13b, and the inner diameter of the fifth through hole 13b1 is set to be slightly larger than the outer diameter of the first protrusion 112 mentioned above.

[0138] Furthermore, with the first protrusion 112 inserted into the fifth through hole 13b1, the fixing plate portion 13b is disposed between the base plate portion 111 of the base member 11 and the bottom plate portion 122 of the leg member 12.

[0139] Thus, the fixing plate portion 13b can be connected to the base member 11 in a vertical direction by sliding (moving) along the first protrusion 112 via the fifth through hole 13b1.

[0140] The buffer device 10, constructed from the above structure, is mounted on a tray 1 (see reference 1) as described above. Figure 2 The system has multiple buffer devices 10 (10 in this embodiment) configured to be clamped between the base frame 21 and the base plate 23 respectively.

[0141] In other words, in this embodiment, multiple (four) buffer mechanism parts (buffer members) 13a are arranged in an orthogonal direction to each other along the axis of the compression coil spring 13a1 to form a buffer unit 13, and multiple (10) buffer units 13 are provided in the base part 2 of a tray 1.

[0142] With this structure, according to the tray 1 in this embodiment, multiple (four) buffer mechanism parts (buffer members) 13a are brought together to form a buffer unit 13. For example, the compressive load applied to the buffer unit 13 can be distributed and borne by each buffer mechanism part (buffer member) 13a, and the buckling generated in each buffer mechanism part (buffer member) 13a can be suppressed, preventing the deterioration of the buffer mechanism part (buffer member) 13a from being accelerated.

[0143] It should be noted that in the buffer device 10 of this embodiment, the composite spring constant of the multiple (four) buffer mechanism parts (buffer members) 13a, which combines each compression helical spring 13a1, is set to 5000 N / mm or less.

[0144] With this structure, according to the tray 1 in this embodiment, even if the multiple glass plates Ga bundled in a stacked state are relatively heavy, multiple (four) buffer mechanisms (buffer members) 13a can effectively buffer impacts, vibrations, etc. applied in any direction.

[0145] As described above, in this embodiment, the tray 1 is a tray that bundles multiple glass plates Ga in a stacked state. The tray 1 is configured to include: a base portion 2; and a mounting platform (support portion) 3, which is disposed above the base portion 2 and supports the mounting posture of the glass plates Ga.

[0146] Here, the base section 2 has: a base frame (base body section) 21, which supports the support platform (support section) 3; and a plurality of buffer mechanism sections (buffer members) 13a, which are disposed on the lower side of the base frame (base body section) 21.

[0147] Furthermore, each buffer mechanism (buffer member) 13a is configured as a composite member consisting of a rubber cylindrical part (cover member) 13a2 and a compression coil spring 13a1 with the axial direction set in the up and down direction.

[0148] In addition, the glass plate bundle M in this embodiment is configured to include: a tray 1, which is constructed with the above-described structure; and a glass plate stack G, which is composed of multiple stacked glass plates Ga and is placed on the base portion 2 of the tray 1.

[0149] With this structure, according to the tray 1 and the glass plate bundle M in this embodiment, for impacts and vibrations applied in the vertical direction, the compression coil spring 13a1 constituting the buffer mechanism (buffer member) 13a can be stretched and contracted axially to absorb and buffer these impacts and vibrations. In addition, for impacts and vibrations applied in the horizontal direction, the compression coil spring 13a1 can be bent in any direction to absorb and buffer these impacts and vibrations.

[0150] Therefore, the buffer mechanism (buffer member) 13a can effectively buffer impacts and vibrations applied in any direction, and can provide sufficient vibration damping performance against impacts and vibrations applied during transportation.

[0151] Example

[0152] Next, embodiments of the present invention will be described in further detail.

[0153] It should be noted that the embodiments shown below are for illustrative purposes only and do not limit the scope of the present invention in any way.

[0154] First, initially, as a sample of this utility model, the aforementioned tray 1 is prepared as an embodiment, and a conventional tray is prepared as a comparative example.

[0155] Here, regarding conventional pallets, a pallet with the same structure as pallet 1 is prepared, except that it does not have multiple cushioning devices 10 but instead has steel sandwiched between the base frame 21 and the base plate 23.

[0156] Next, a glass plate stack G consisting of a predetermined number of glass plates Ga was placed and bundled on tray 1 (as an example) and tray (as a comparative example) in a longitudinal orientation.

[0157] Here, regarding the glass plate laminate G, 330 glass plates Ga with an external dimension (vertical dimension × horizontal dimension) of (2500mm × 2200mm) and a thickness of 0.5mm are prepared, and these 330 glass plates Ga are stacked together to construct the glass plate laminate G.

[0158] Foamed resin sheets are sandwiched between the Ga glass plates as protective sheets.

[0159] Furthermore, commercially available accelerometers were installed on both pallet 1 (as in the example) and pallet (as in the comparative example). Then, using a specified transport vehicle, the two pallets were simultaneously transported to their designated transport destinations, and the accelerations measured during the transport were compared.

[0160] Here, regarding the accelerometer, an accelerometer (model: DR-20) manufactured by SLIK Corporation was used.

[0161] In addition, regarding the installation position of the accelerometer in each tray, it is installed on the upper surface of the front end of the base frame 21 (more specifically, the frame part 21a) and in the center of the left and right direction.

[0162] The acceleration results measured in tray 1 (as an example) and tray (as a comparative example) are respectively... Figure 5 As shown in the image.

[0163] As shown in this figure, an acceleration of approximately 8G was applied during handling in the pallet used as a comparative example.

[0164] On the other hand, in pallet 1, which is an example, an acceleration of about 5G is applied during handling, resulting in a reduction of about 60% in acceleration compared to conventional pallets.

[0165] The above describes one embodiment of the present utility model, but the present utility model is not limited to this embodiment in any way and is merely an example. Of course, it can be implemented in various ways without departing from the spirit of the present utility model. The scope of the present utility model is indicated by the description of the utility model technical solution, and also includes all equivalent meanings and modifications within the scope of the utility model technical solution.
