Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cathode ray tube glass panel holding and holding material for holding and holding a cathode ray tube glass panel with a face portion facing upward and a seal edge portion facing downward with a buffering material sandwiched from above and below. Regarding the method.
[0002]
[Prior art]
In general, a cathode ray tube glass panel (hereinafter, also simply referred to as “panel”) is a rectangular hollow glass body that is open on one side, and has a screen area on which an image is displayed when assembled as a cathode ray tube. And a skirt portion provided substantially perpendicular to the face portion and having a seal edge portion at an end portion, and the face portion has an R portion, a so-called blended R portion, at a peripheral portion of the screen region. ing.
[0003]
Conventionally, as a holding material for storing or transporting a panel having the above-mentioned shape, a cushioning material such as polystyrene foam, polyethylene foam, a packaging member such as paper or plastic, or a combination thereof is used. It has been.
[0004]
Various proposals have been made for the shape and structure of such a holding material. Among them, as a first conventional technique, a panel is placed on a box-like body having an opening in the upper part (flat-laying). And a holding material that is held in a box-like body by providing a cushioning member made of foamed polystyrene at the bottom peripheral portion or corner portion of the panel.
[0005]
As a second prior art, the blend R portion and the skirt portion on the short side of the panel are held so as to be covered from both sides with a cushioning member made of foamed polystyrene, and the panels thus held are stacked in a plurality of stages to form a box shape. The holding material stored in the body is exemplified.
[0006]
However, since the holding materials of the first and second prior arts are not integrated, the “play” for each individual part is large, and the panel may be scratched by vibration during transportation. It was necessary to coat with a material (for example, protective paper). In addition, since corrugated paper is used as an exterior component that suppresses lateral displacement, problems such as strength changes due to moisture absorption may occur.
[0007]
In addition, since it is composed of parts made of corrugated paper and polystyrene foam, there is a problem that the number of parts per transport pallet increases and its management is complicated. Furthermore, since the exterior parts are assembled from corrugated cardboard, they are bulky when stored after use, so they require a large storage space, and further reduction of the space requires dismantling and sorting of the holding material. There was a problem.
[0008]
In view of such a problem, it is made of only a cushioning material such as polystyrene foam, the number of parts is small, the management of the holding material is easy, the pre-assembly work and the clean-up work after removing the panel are simple, and bulky after use. Providing no holding material has been a challenge.
[0009]
As a solution to this problem, a holding material that holds a vertically placed panel with one face of the skirt facing down and the face in the vertical direction sandwiched from above and below by a pair of cushioning members made of foamed polystyrene has been developed as a third prior art. It was. In this holding material, a plurality of recesses for inserting the skirt portion of the panel are provided at regular intervals, and the upper and lower skirt portions are inserted into the recesses of the holding material arranged above and below the panel. The plurality of panels placed vertically are held from above and below by a pair of buffer members. Therefore, this holding material can solve the above-mentioned problems in the first and second holding materials of the prior art described above, and is excellent in terms of cost.
[0010]
Although different from the panel holding material of the present invention, Japanese Patent Application Laid-Open No. 11-349075 similarly discloses that a cathode ray tube is made up of a top holder, an intermediate holder, and a bottom holder made of foamed polystyrene with the face portion facing sideways. A method of sandwiching and holding a plurality of stacked layers is disclosed.
[0011]
However, with the recent increase in size of televisions, the size and weight of panels have increased, and the holding material of the third prior art requires work to stand the panel and turn the face sideways during use. In the case of a large panel, there is a problem that this work burden becomes very large. In addition, since the plurality of panels are held vertically, it has been substantially difficult to unpack and mechanically remove the panels, which has been a major obstacle to automating the removal operation.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a cathode ray tube glass panel storage / transport holding material that can hold a panel with a face portion facing upward, sandwiched by a cushioning material from above and below, and can be stacked in multiple stages. The holding material is laid on the top of the uppermost staged panel, the sandwiching part sandwiched between each stage, and the lower part of the lowermost panel. The bottom member is composed of three members. Therefore, when these panels are used to hold the panel for storage and transportation, three members are used as a set. Here, the storage and transportation of the panel refers to storage of a stock panel in a panel manufacturer or a cathode ray tube manufacturer, or transportation in a factory or at the time of shipment transportation.
[0016]
In the present invention, the number of stacked panels and the number of panels held in one stage vary depending on the size and weight of the panels. In general, the larger the panel, the smaller the number of stages and the number of stages. For example, in the case of a large panel having a size of 65 to 106 cm, the number of steps is preferably about 4 to 8, and the number of steps is preferably about 1 to 5 in view of the strength of the holding material and workability. When the number of panels in one stage is four or more, it is preferable to arrange and hold a plurality of panels in the vertical and horizontal directions.
[0017]
The holding material can be safely held without being scratched even if it comes into direct contact with the panel, has a buffering effect against a normal impact during transportation, and has a rigidity required as a holding member for the panel. Formed by a shock-absorbing material. As this buffer material, polystyrene foam (foamed polystyrene), foamed polyethylene, rigid foamed urethane, a foam of a copolymer of styrene and ethylene can be preferably used. Among them, a polystyrene foam which is widely used as a packaging member for various articles and has a proven record is particularly preferable because it has the above-mentioned characteristics and is relatively low cost.
[0018]
Each member of the zenith member, the sandwiching member, and the bottom member constituting the holding material is a flat plate-shaped molded member having a unique shape and function as described later, and is designed based on each shape and function. Has irregularities and openings. That is, the sandwiching member and the bottom member have convex portions on the front side surface for positioning the panel in contact with the end portions of the skirt portion of the panel placed on each of the sandwiching member and the bottom member. Positioning when placing the panel on the sandwiching member and the bottom member, and the placed panel being transported by providing this convex part so as to contact each side or corner part of the rectangular skirt part Even if it receives vibration or lateral force, it can be held so as not to fluctuate on the holding material, that is, not to be laterally displaced.
[0019]
In the present invention, the form (length, height, width, etc.) of the convex part is not specified, but the height H of the convex part is preferably in the range of 5 to 60 mm, more preferably in the range of 15 to 30 mm. When H is less than 5 mm, it causes a lateral shift of the panel, which may cause damage or breakage, and also makes it difficult to align the position when the panel is placed, resulting in poor workability. If H exceeds 60 mm, it is too high, and is easily damaged when subjected to an external force. In addition, workability is deteriorated and the amount of material used increases, which is uneconomical.
[0020]
In addition, on the back side surfaces of the zenith member and the sandwiching member, a recess is formed for fitting into the face portion of the panel provided directly below each. In a preferable holding material, an opening having a predetermined size is provided in the recess. By providing openings in the recesses of the sandwiching member and the zenith member, the weight of the holding member can be reduced and the cost can be reduced. In addition, since air permeability can be secured in the face portion of the stepped panel with the zenith member interposed, the problem of dew condensation can be eliminated or reduced. Therefore, although it is preferable to provide an opening part in each recessed part of a pinching member and a zenith member, an opening part may not be provided in the recessed part of a zenith member.
[0021]
In the present invention, it is preferable that the opening is provided so that the opening area is a fixed ratio with respect to the area of the recess. As this ratio, the area of the dent is S ₁ , The area of the opening S ₂ When 0.1 ≦ S ₂ / S ₁ A range of ≦ 0.75 is preferred. S ₂ / S ₁ Is less than 0.1, the area of the opening is relatively small, and there is a risk that optimum air permeability cannot be obtained. Furthermore, since the amount of use of, for example, polystyrene foam, which is a material for the holding material, increases, it is disadvantageous in terms of weight reduction (cost reduction). On the other hand, S ₂ / S ₁ If it exceeds 0.75, it is preferable for weight reduction, air permeability, etc., but the rigidity of the holding material is lowered as will be described later, so that it tends to bend and workability may be deteriorated.
[0022]
In the case where openings are provided in the recesses of the sandwiching member and the zenith member, it is preferable to obtain a predetermined opening area with a plurality of openings rather than providing a single large opening. That is, the area is S ₂ Instead of providing only one opening, a plurality of openings are distributed in the recesses to provide S as a whole. ₂ To get an area of. The reason is that a problem arises in that the rigidity of the holding material is greatly reduced by providing a large opening in order to ensure sufficient air permeability in one opening. On the other hand, in the case where a plurality of openings are provided, a beam-like holding material always exists between the openings even when the total area of the openings is widened. Can be prevented. In addition, as a shape of an opening part, square shape, circular shape, or another shape can be selected suitably.
[0023]
In the present invention, the zenith member, the sandwiching member, and the bottom member form a rectangular plate-like body. The planar shape of this plate-like body is not specified because it varies depending on the size, type, number, holding method, etc. of the panel to be held, but the planar shape of each member used as a set is usually the same or almost the same. Yes. In addition, the thickness of the plate-like body is different because the optimum thickness is usually selected for each member in a preferred embodiment in order to reduce the weight, and the zenith member that does not need to be provided with a convex portion The thickness of the bottom member which does not have a dent part is thin compared with the clamping member. Thus, the thickness of the holding material is selected over a relatively wide range due to the difference in thickness depending on each member. Specifically, the maximum thickness when projected in the lateral direction is in the range of about 25 to 185 mm. Can be selected. And although the holding material has a specific shape by each member, all can be easily integrally formed from, for example, foamed polystyrene.
[0024]
Next, embodiments of the present invention will be described with reference to the drawings. 2 to 7 exemplify each member (zenith member, sandwiching member, bottom member) of a preferable holding material of the present invention. The holding material of this example is a case where two panels are held in a single row with their face portions facing upward, and each member is integrally formed from expanded polystyrene.
[0025]
First, the zenith member 1 mounted on the uppermost panel will be described with reference to FIGS. 2 and 3 show perspective views of the front side surface and the back side surface of the zenith member 1, respectively. On the back side surface of the zenith member 1, there is provided a recess 7 for fitting into the face portion of the panel as shown in FIG. Therefore, the shape of the recessed portion 7 is substantially the same rectangular shape as the face portion. For example, a step portion (see FIG. 5) is formed around the inner surface of the recess portion 7, and the step portion contacts the peripheral portion (blend R portion) of the face portion, and a holding material is provided on the screen portion. It is designed not to touch substantially. The depth of the recessed portion 7 is not limited. However, if the depth is too deep, not only the workability of attaching to and detaching from the face portion is deteriorated, but also the thickness of the zenith member 1 is increased, which is disadvantageous in terms of weight reduction and cost. Usually, it is preferable to have a depth that allows fitting to the vicinity of the boundary between the blend R portion or the skirt portion and the blend R portion of the face portion of the panel. In addition, the shape and depth of this recessed part 7 are the same also in the recessed part of the clamping member mentioned later.
[0026]
It is important that the zenith member 1 has a recessed portion 7 formed on the back side surface, and the front side surface of the zenith member 1 has a flat portion other than the opening portion as in this example in terms of appearance and ease of use. Is preferable. However, if there is no particular hindrance, the surface can be uneven, and is not necessarily flat.
[0027]
As shown in the figure, an opening 8 is provided in the recess 7. In this example, four rectangular openings 8 are arranged vertically and horizontally in accordance with the shape of the recesses 7 for each recess 7, and the weight of the zenith member 1 is reduced by these openings 8. And ensuring air permeability. In this case, the total area S of the four openings 8 as described above. ₂ Is the area S of the recess 7 ₁ The ratio is preferably a certain ratio. In this example, S ₂ / S ₁ Is about 0.5.
[0028]
Furthermore, the back side surface of the zenith member 1 of this example is provided with a recess 10 between the recess 7 and the recess 7 on the peripheral edge on the long side. This dent 10 is for accommodating a desiccant pocket (described later) provided on the front side surface of the sandwiching member when the holding material is laminated for storage before use or after use. It corresponds to the desiccant pocket. When the zenith member 1 is laminated on the sandwiching member, the projecting portion 11 is accommodated in the recess portion 7 by fitting the desiccant pocket protruding on the front side surface of the sandwiching member into the recess 10. The overlapping height of the zenith member 1 and the sandwiching member can be shortened, and since both of these are fixed in the surface direction, they do not shift laterally.
[0029]
Next, the sandwiching member 2 will be described with reference to FIGS. 4 and 5. 4 is a perspective view of the sandwiching member 2, and FIG. 5 is a cross-sectional view taken along the line AA in FIG. As is apparent from FIG. 5, a recess 7 is formed on the back side surface of the sandwiching member 2, and an opening 8 is provided in the recess 7. However, since the dent 7 and the opening 8 are the same as the zenith member 1 as described above, the front side surface will be described. Moreover, the same sandwiching member 2 can be used regardless of the number of stacked panels.
[0030]
As shown in FIG. 4, a convex portion 11 for positioning the panel is provided on the front side surface of the sandwiching member 2. This convex portion 11 is a means for preventing positioning and lateral displacement of the panel by contacting or engaging with the inner surface of the end portion of the skirt portion of the panel 4 (see FIG. 5) placed on the sandwiching member 2. In this example, two protrusions are provided on each long side and short side of the end portion of the rectangular skirt portion as a convex shape having a height of about 20 mm. In this case, when the length of the convex portion 11 is provided so as to substantially match the length of the long and short sides of the rectangular opening 8 as in this example, a reduction in rigidity of the sandwiching member 2 caused by the opening 8 is suppressed. It is preferable because it is possible.
[0031]
However, the shape of the convex portion 11 can be changed without being limited thereto. For example, convex portions having a short length may be provided along the contour of the end portion of the skirt portion, or may be formed as continuous long convex portions. Further, from the viewpoint of weight reduction and appearance of the sandwiching member 2, the convex portion 11 is usually provided to engage with the inner surface of the skirt portion end portion as in this example, but it engages with the outer surface of the skirt portion end portion. It may be formed into a concave groove shape that can be fitted into both the inner and outer surfaces of the skirt end, or that the skirt end can be fitted by providing protrusions on the inside and outside of the skirt end. You may form in. Furthermore, although not shown in the figure, the sandwiching member in the inner portion of the skirt portion can be raised to form a convex portion without forming the convex portion with a predetermined width as in this example.
[0032]
As shown in FIG. 4, a desiccant pocket 9 is provided between the left and right panels (not shown) with the insertion port facing outward on the periphery of the center of the long side of the upper surface of the sandwiching member 2. ing. And the recessed part 10 is normally provided in the back side of the said desiccant pocket 9 on the back side surface of the clamping member 2 similarly to the back side surface of the zenith member 1 of FIG.
[0033]
Further, the sandwiching member 2 of this example is provided with a step portion 15 by removing a part of the peripheral portion of the sandwiching member 2 at a position corresponding to the corner portion of the rectangular skirt portion as shown in FIG. ing. The step portion 15 functions so that a hand can be easily inserted under the end face of the skirt portion when handling the panel, and air permeability between the inside and the outside of the panel can be obtained through the step portion 15.
[0034]
Next, the bottom member 3 will be described. 6 and 7 show perspective views of the front side surface and the back side surface of the bottom member 3, respectively. As shown in FIG. 6, a convex portion 11 is provided on the front side surface of the bottom member 3 in the same manner as the sandwiching member 2. However, unlike the sandwiching member 2, the back side surface is a flat surface as shown in FIG. It is preferable that the bottom surface of the bottom member 3 be flat in this way because the bottom member 3 can be easily laid on a base, for example, when packaging or packing a panel. However, it does not necessarily have to be flat. For example, a recess can be provided in a region where the vertical load of the panel is not applied, so that the weight can be reduced.
[0035]
Moreover, the peripheral protrusion 12 can be provided in the periphery of the front side surface of the preferable bottom member 3 like this example. The peripheral protrusion 12 is a convenient means for securing the peripheral strength of the bottom member 3 and preventing the intrusion of dust and the like. A notch 14 is provided for insertion. In this example, the recessed hole 13 provided in the corner part of the bottom member 3 where the end face of the skirt part contacts is ensured of air permeability between the inside and outside of the panel, similarly to the step part 15 of the sandwiching member 2. It is intended for hand insertion when handling panels.
[0036]
Although not shown in the holding material of this example, in order to further reduce the weight of the holding material and improve air permeability, portions of each member that are not directly related to the panel holding, for example, two panels You may provide a transparent hole in the margin part between. If the purpose is only weight reduction, a recess can be formed in the margin portion to make it thinner.
[0037]
Next, a method for holding the panel using the holding material will be described. FIG. 1 is a front view of a packaging body in which two panels 4 are held one by one and stacked in seven stages to pack 14 panels, part of which is cut away and shown in a sectional view. The cut-out cross section is a central portion (A-A portion in FIG. 4) of the holding material.
[0038]
The panel 4 is held by a holding material from above and below with the face portion facing up, and is stacked on the base 5. The base 5 is a strong wooden frame, and has a fork insertion hole so that it can be transported in the factory and loaded and unloaded at the time of transport with a forklift truck. The bottom member 3 is laid on the base 5, and the two panels in the first stage are placed with the inner surface of the end portion of the skirt portion aligned with the convex portion 11 of the bottom member 3. Next, the sandwiching member 2 is mounted on these panels by fitting the recessed portion 7 on the back side face to the face portion, and the second two panels are projected on the sandwiching member 2. 11 is placed in accordance with the position of 11, and the sandwiching member 2 is sandwiched for each stage, and the 7-stage panels are stacked by the same method. Then, the zenith member 1 is mounted on the uppermost panel by fitting the recessed portion 7 on the back side surface to the face portion.
[0039]
Thus, the stepped panels are held from above and below by the bottom member 3, the sandwiching member 2, and the zenith member 1. That is, the first-stage panel is held by the bottom member 3 and the sandwiching member 2 in a state where no lateral deviation occurs at a position determined by the convex portion 11 of the bottom member 3. At the same time, the sandwiching member 2 is fixed so as not to move by fitting the recessed portion 7 on the back side surface to the face portion of the first-stage panel. The panel between the second stage and the sixth stage is similarly held by the sandwiching member 2, and the uppermost panel is held by the sandwiching member 2 and the zenith member 1.
[0040]
In the present invention, the vertical load of the panel stepped through the holding material in this way is substantially supported by the skirt portion of the lower panel sequentially through the holding material. For this purpose, the holding material is sandwiched only by the peripheral portion of the face portion of the panel and the end face of the skirt portion, so that a load is not substantially applied except for the peripheral portion of the face portion (blend R portion). As a result, even if the panel receives an impact during transportation, the shock-absorbing holding material absorbs it, and the load is supported by the skirt that is strong against vertical load, so it can be safely done without damaging the panel. Can be transported.
[0041]
Further, according to the present invention, a top cover 6 made of, for example, corrugated paper (see FIG. 1) can be put on the top member 1. The upper lid 6 serves to protect the zenith member 1 and the panel 4 from external force, wind and rain, dust and the like. This is particularly effective in the zenith member 1 provided with the opening 8 as in this example. Although not shown, by inserting a lower lid between the base 5 and the bottom member 3 such that the upper lid 6 is turned in the reverse direction, wind and rain can be generated from the notch 14 of the bottom member 3 and the like. It can prevent dust and the like from entering.
[0042]
Furthermore, when it is necessary to take countermeasures against dew condensation on the panel depending on the storage period and location, or transportation conditions, a desiccant is inserted into the desiccant pocket 9 provided in advance in the sandwiching member 2. In this case, since the desiccant pocket 9 is exposed to the outside, the desiccant can be easily inserted after the panel is set. Furthermore, in order to protect the panel thus packaged from wind and rain, dust, etc., the entire packaged package can be covered with a synthetic resin film as necessary.
[0043]
Moreover, a panel can be hold | maintained only by the bottom member 3 and the top | zenith member 1 of this invention, and also a panel can be piled up predetermined number in this state. That is, the panel is held between the bottom member 3 and the zenith member 1 by mounting the zenith member 1 on the panel placed on the bottom member with the recess 7 fitted to the face portion. To do. When a plurality of panels are further stacked, another bottom member is mounted on the top member, the second panel is similarly held, and this is repeated to stack a desired number of stages. Of course, the panels can be stacked while being held by the bottom member 3 and the zenith member 1. In this case, a state in which another bottom member is mounted on the top member corresponds to the sandwiching member in the present invention.
[0044]
Then, when the panels are arranged in this way, for example, by providing unevenness that can be fitted to each other on the joint surface between the zenith member 1 and the bottom member 3 to be stacked. Prevent lateral shift of the stepped panels.
[0045]
【The invention's effect】
In the present invention, as described above, the zenith member, the sandwiching member, and the bottom member can be formed only by the cushioning member such as the foamed polystyrene, so that a holding material that is lightweight and has a small number of parts can be obtained. As a result, the management of the holding material becomes extremely easy, and the workability of the assembly of the holding material and the tidying up after removing the panel is small, so that workability is improved and the cost of the holding material can be further reduced.
[0046]
Also, align the skirt end of the panel with the convex part provided on the front side of the holding material, and fit the recessed part of the other holding material to the face part. Since it can be held and stacked in multiple stages, the burden of panel packaging can be reduced, and since the panels are placed flat, the machine can be used while removing the holding material from the top in order. Can be easily removed.
[0047]
In addition, since the holding material after the panel is taken out can be laminated without creating a gap, the volume can be easily reduced and stored without being bulky, and no special disassembly or sorting work is required. Moreover, by providing a desiccant pocket protruding on the front side surface of the holding material and providing a recess that can accommodate this desiccant pocket on the back side surface of the other holding material to be laminated, the holding material is not displaced. Can be stacked.
[0048]
If the face part is a flat panel, the depth of the recessed part provided on the back side of the holding material can be shallower than that of the curved panel, and the thickness of the holding material should be reduced accordingly. Since the holding material can be made light and not bulky, the present invention is suitable for a panel having such a flat face portion.
