Description

  The present invention relates to a transportation gantry device for the purpose of reducing vibration and impact of a rigid rectangular (quadrangle) large thin glass substrate during transportation of cargo or the like.

A substrate typified by a display device is a thin layer and has a large size, so that it is difficult to store it in a flat state, and it is usually stored in a state where the central portion is slightly curved downward. Further, since the functional layer is provided on the surface, there is a problem that the mutual surfaces of the substrates should not be brought into contact with each other.
Furthermore, it is necessary to accumulate and store at a high density in order to reduce transportation costs and save space, and it is also required to protect the substrate from damage and cracks during transportation.

  Examples of large thin glass substrates include color filters for plasma and liquid crystal display, intermediate products thereof, and various other substrates.

  The present invention is such that the large pallet glass substrate is bent and horizontally placed, and the inner pallet that can be stably stacked and stacked in multiple stages, and the large thin glass substrate are stacked in multiple stages. The present invention relates to a transportation gantry device comprising a combination with an anti-vibration pallet for safely transporting an inner pallet so that cargo collapse and rattling do not occur.

  Large thin glass substrates such as liquid crystal display panels, plasma display panels, and color filters used in such display devices are plate-like objects having a functional layer on the surface. When transporting the plate-like material, it is important to transport it without damaging or soiling the functional layer on the surface. When transporting such plate-like objects, it is necessary to store them in parallel at predetermined intervals for each sheet so that the functional layers on the surface of the plate-like objects are protected so that the surfaces do not contact each other or between the front and back surfaces. .

  In addition, these thin glass substrates, such as color filters and their intermediate products, have a large display device itself, and even for small display devices, cost reductions have been adopted for multifaceted manufacturing methods. A large-sized thin glass substrate is used.

  A glass material having a certain rigidity is used for the color filter substrate. Even if a large-sized thin glass substrate having a size of about 1 square meter is used, the thickness of the glass substrate is 0.5 mm to 1 mm. Only about 0mm. When such a thin and large-sized glass substrate is transported in a state where it is placed on a flat surface as conventionally used, the occurrence of jumping due to vibration or impact during transportation becomes larger, and the functional layer on the surface becomes the original. There is a possibility of damaging the substrate itself. However, when a thin and large-sized glass substrate is placed in a horizontally curved state, a repulsive force acts against the force of the glass substrate itself returning to the horizontal direction. Less likely to occur. However, with only the inner pallet that can be bent and placed stably, it is difficult to withstand vibrations and shocks especially when transporting cargo on the road. The combination of is effective.

A large thin glass substrate called the sixth generation has a size of 1850 mm × 1500 mm or 1800 mm × 1500 mm, and a stacked body in which the substrates are integrated at a high density has a total weight of about 1.5 tons or more.
By the way, the glass substrate called the eighth generation has a size of 2200 mm × 2500 mm, and the ninth generation has a size of 2400 mm × 2800 mm.

  An anti-vibration pallet (support frame) is known in which an anti-vibration element is provided between an upper frame and a lower frame in order to reduce vibrations and shock transmission during transportation on the road from cargo or the like. In the support frame 100 described in FIG. 8 of Patent Document 1, the load L is mounted on the support frame 100, but there is no description of a fitting structure for mounting at an accurate position, and is described in FIG. 9. It does not appear that the fitting structure is described in the supporting frame 100. The leg 6 of the vibration control panel 1 described in FIG. 1 of Patent Document 2 has a fitting structure with the pallet 7, but the fitting structure between the vibration damping panel 1 and the pallet 7 It is not a fitting structure for mounting on an accurate position.

  Under such circumstances, in particular, liquid crystal display panels, in particular, require the manufacture of larger color filter-formed substrates, without causing damage to the transport of the color filter substrate and its intermediate process substrate. There is a need to reduce costs by improving transportation efficiency and saving storage space.

  In order to prevent such a glass substrate from becoming bulky, it is possible to integrate it at a high density and transport it safely. In addition to saving space in the storage area, it is possible to reduce the number of transportation and operate small cargo vehicles. This will contribute to the reduction of logistics costs.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the transportation gantry device 100.
The transportation gantry device 100 includes an inner pallet 10 and an anti-vibration pallet 20 that can be stacked and placed in multiple stages horizontally by bending a large thin glass substrate. This is a structure that is fitted and operated by the fitting protrusion 24 of the vibration proof pallet 20 and the fitting frame 12 (FIG. 3) on the back surface of the inner pallet 20.

FIG. 2 is a plan view of the vibration isolating pallet 20.
The anti-vibration pallet 20 includes a plurality of anti-vibration elements 23, an upper frame body 21, and a lower frame body 22. The upper frame 21 uses a metal plate made of a SUS material (Steel Use Stainless) with a plate thickness of 20 to 25 mm, and a frame frame portion 21 (made of 21a, 21b, 21c, and 21d) made of a metal frame on four sides. The beam member 25 is fixed between the center position of the frame frame portion 21a and the center position of the frame frame portion 21b, and further, the beam members 26 (26a) extending in parallel with the beam member 25 on both sides of the beam member 25. , 26b). Next, the beam member 27 and the beam members 25 and 26 are combined and fixed between the center position of the frame frame portion 21c and the center position of the frame frame portion 21d. In other words, the beam members 25, 26, and 27 are arranged as described above as reinforcement of the frame portion 21.

  The upper frame body 21 is formed by fixing each member of the frame frame portion 21 and the beam members 25, 26, and 27 by welding. The lower frame body 22 is of the same material and structure as the upper frame body 21 with a strong structure and high strength.

  The anti-vibration pallet 20 has a structure in which an upper frame 29 and a lower frame 30 are connected only by a plurality of anti-vibration elements 23. The anti-vibration elements 23 include four corners, four sides ( 21 a, 21 b, 21 c, 21 d), the center position of each side, the center of the frame portion 21 (intersection of the beam member 25 and the beam member 27, a total of nine vibration isolation elements 23 are arranged.

  In the upper frame 21, the beam member 26a and the frame frame portion 21d are fixed to each other at a substantially intermediate position between the frame frame portion 21a and the beam member 27, and a fitting beam member 28a extending in parallel with the beam member 27 is fixed by welding. . The fitting projection 24a is arranged at the corner of the beam member 27 side at the connection portion between the frame frame portion 21d and the fitting beam member 28a.

  The protrusion 24a for fitting has a triangular prism shape formed by using a SUS material (Steel Use Stainless) with a thickness of 2 mm. The triangular prism is reinforced with a reinforcing plate inside, and the two sides of the triangular prism in a plan view are formed. The frame frame portion 21d and the fitting beam member 28a are in contact with each other and fixed with bolts, and are further brought into contact with the frame frame portion 21d and the fitting beam member 28a from the substantially middle portion of the height of the triangular prism to the upper part. The surfaces of the triangular prisms are each processed so as to be inclined inward of the triangular prisms.

  The fitting protrusions 24 (24a, 24b, 24c, 24d) are formed by fitting the fitting protrusions 24b at the positions of the sides of the frame frame portion 21d in which the beam members 27 of the fitting protrusions 24a are line symmetrical. The fitting projections 24c and 24d are arranged in the same shape and structure as the fitting projection 24a at the side of the opposing frame frame portion 21c in which the beam members 25 of the projections 24a and 24b are axisymmetric. Yes.

  The fitting protrusions 24 are arranged in four places, two on the side of the frame frame 21d and two on the sides of the opposing frame frame 21c. As a result, even if they are slightly displaced and are likely to be placed on the inner pallet 10 on the anti-vibration pallet 20, they can be placed at accurate positions and damage to the fitting projections 24 can be reduced.

  Further, the fitting protrusion 24 is disposed between the two vibration isolation elements 23. The anti-vibration pallet 20 is placed directly on the cargo bed on a cargo vehicle or the like. At this time, when the vehicle runs, vibrations transmitted from the wheels to the cargo bed along the unevenness of the road are transmitted to the luggage through the vibration isolation element 23. Therefore, by disposing the fitting protrusion 24 between the two vibration isolating elements 23, the fitting protrusion 24 is not directly subjected to the vibration of the vibration isolating element 23, and the vibration is reduced. Damage to the fitting protrusion 24 is reduced.

  The fitting projection 24 is arranged at a diagonal position between the fitting projection 24a and the fitting projection 24a, and is fitted in two places with the fitting projection 24c on the side of the opposing frame frame portion 21c. Although the state can be formed, the total weight of the inner pallet 10 in which 150 large-sized thin glass substrates are housed in a frame member and laminated is about 1.5 tons or more, so there are two places on one side facing each other. It is preferable to arrange a total of four fitting protrusions 24.

Here, in this description, the fitting projections 24 are formed on the front and rear sides of the frame frame portion 21 of the upper frame body 29 in plan view, but are similarly formed on the left and right sides of the frame frame portion 21. be able to.

Further, the fitting projections 24 can be provided other than the front and rear sides and the left and right sides of the frame frame portion 21 of the upper frame 29 in plan view, but the interval between the pair of fitting projections 24 facing each other is long. Therefore, it is preferable to provide the frame frame portion 21 on the front and rear sides or on the left and right sides.

  Next, as shown in FIG. 1, the inner pallet 10 is a structure in which a large thin glass substrate holder 13 is placed on the upper surface of a pallet composed of an upper frame body 11 and a lower frame body 12. The weight of the multi-layered layer is 1.5 tons or more, and in order to support it, a metal plate made of SUS material (Steel Use Stainless) with a plate thickness of 20 to 25 mm is used and assembled by welding, making the structure solid The strength is also increased.

FIG. 3 is a plan view of the back surface of the inner pallet 10.
The lower frame 12 of the inner pallet 10 has a structure in which the fitting protrusion 24 is removed from the upper frame 21 of the anti-vibration pallet 20. The portions excluding the fitting protrusions 24 (24a, 24b, 24c, 24d) become fitting frame parts 13 (13a, 13b, 13c, 13d), respectively, and the fitting protrusions 24 are fitted together. In FIG. 3, the fitting frame portion 13 is formed in a frame shape, but may be formed in a hole shape in which the fitting protrusion 24 can be accommodated.

  The inner pallet 10 and the anti-vibration pallet 20 are made of SUS material (Steel Use Stainless) from the viewpoint of reducing vibration in consideration of vibration during transportation. However, if you want to reduce the weight, use aluminum material. Also consider using.

  Since the transportation gantry device 100 of the present invention has a structure in which the inner pallet 10 and the anti-vibration pallet 20 are separated, the transportation and storage in the factory can be performed only by the inner pallet 10, and transportation. Since the anti-vibration pallet 20 is required only at the time, it is not necessary to prepare the anti-vibration pallets 20 having the expensive anti-vibration elements 23 for the number of the inner pallets 10, which contributes to cost reduction. In addition, by attaching fitting marks 70 for positioning on the side surfaces of the inner pallet 10 and the vibration isolating pallet 20, the forklift operator can easily operate when placing the inner pallet 10 to improve workability. It is done.
