BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 6 is an explanatory view of use of the load collapse prevention device 1 of the present embodiment. As shown in the figure, the collapse prevention device 1 of the present embodiment is used for winding a stack T in which a plurality of packing boxes m are stacked with a binding belt 2 and fixing the packing box m, such as a cardboard box. In order to prevent the collapse of the load box m.
The collapse prevention device 1 can be used not only for cardboard boxes, but also for various packing boxes such as square cans such as kerosene cans, building blocks such as concrete blocks, and packing materials in which a plurality of bottles are bundled.
[0009]
FIG. 1 is a schematic perspective view of the load collapse prevention device 1 of the present embodiment. As shown in FIG. 1, the load collapse prevention device 1 of the present embodiment includes a corner plate 10 and an insertion plate 20.
In addition, the load collapse prevention tool 1 may be one in which a separate insertion plate 20 is attached to the corner plate 10 or one in which these members 10 and 20 are integrally formed.
[0010]
First, the corner plate 10 will be described.
The corner plate 10 has long edges joined together in a state where two rectangular plate members 11 and 12 intersect at right angles. For this reason, the plate materials 11 and 12 can be respectively applied to both side surfaces sandwiching the side portion of the packing box m.
The corner plate 10 may be formed by bending a single rectangular plate at right angles along bisectors parallel to the long edges on both sides.
[0011]
The plate members 11 and 12 are plates made of a synthetic resin such as polyethylene terephthalate, vinyl chloride, a hard foam material, and a recycled resin. Since these plate materials 11 and 12 have rigidity, the plate materials 11 and 12 can be applied to the side of the packing box m in the integrated body T to protect the side of the packing box m.
The corner plate 10 may be made of not only a synthetic resin plate but also a metal plate of aluminum, stainless steel, titanium or the like. In this case, the corner plate 10 can be made robust, and deterioration and damage due to ultraviolet rays can be prevented, which is preferable.
[0012]
Next, the insertion plate 20 will be described.
FIG. 5 is a longitudinal sectional view when the load collapse prevention device 1 of the present embodiment is used. As shown in FIGS. 1 and 5, when the corner plate 10 is erected, it is located above the middle position in the longitudinal direction and below the upper end of the corner plate 10, inside the corner plate 10. An insertion plate 20 is provided. The insertion plate 20 is inserted into a gap between the upper and lower packing boxes m, m, and is a plate made of a synthetic resin such as polyethylene terephthalate, vinyl chloride, a hard foam material, and a recycled resin.
In this corner plate 10, a portion above the mounting position of the insertion plate 20 is the upper support portion 1A, and a lower portion is the lower support portion 1B.
The material of the insertion plate 20 may be not only a synthetic resin but also a metal such as aluminum, stainless steel, or titanium. In this case, the corner plate 10 can be made robust, and deterioration and damage due to ultraviolet rays can be prevented, which is preferable.
[0013]
Since the insertion plate 20 is located above the middle position of the corner plate 10, the center of gravity of the load collapse prevention device 1 in the upright state can be located below the mounting position of the insertion plate 20 on the corner plate 10. it can.
Therefore, as shown in FIG. 5, when the insertion plate 20 of the load collapse prevention device 1 is inserted into the gap between the upper and lower packing boxes m, m in the stack T, the insertion plate 20 and the side of the packing box m are inserted. The lower support portion 1B of the corner plate 10 is pressed down to the packing box m with the contact portion with the side as the fulcrum Q, so that the stability of the load collapse prevention device 1 can be enhanced.
Therefore, it is possible to prevent the load collapse prevention tool 1 from dropping off naturally from the gap between the packing boxes m, m.
[0014]
Moreover, the insertion plate 20 is attached below the upper end of the corner plate 10 (for example, 60 mm). For this reason, in the corner plate 10, the upper supporting portion 1A at a certain height or more can be secured above the mounting position of the insertion plate 20, so that the upper supporting portion 1A The side portion can be supported reliably.
In addition, when the packing box m is a cardboard box, since the height is often 280 to 300 mm, the length of the corner plate 10 is about 330 to 420 mm, and the mounting position of the insertion plate 20 is A position at least 60 mm away from the upper end is preferred. In this case, the two upper and lower packing boxes can be reliably supported.
[0015]
By making the lower supporting portion 1B of the corner plate 10 longer than the sum of the height of the packing box m and a certain distance (for example, 60 mm), the stacking body T of three-tiered packing boxes can be used. The corner plate 10 can be simultaneously applied to the sides of the three-stage packing boxes m to protect the sides of each packing box m. For this reason, the mounting work of the load collapse prevention tool 1 can be reduced, and the binding work can be greatly reduced.
[0016]
In addition, by further lengthening the lower supporting portion 1B of the corner plate 10, even in the case of a stack T having four or more stacks, the corner plate 10 can be simultaneously applied to the side portions of the four or more packing boxes m. , The side of each packing box m can be protected. For this reason, the mounting work of the load collapse prevention tool 1 can be reduced, and the binding work can be greatly reduced.
Further, when the lower support portion 1B is long, a belt through hole for passing a new binding belt may be additionally formed slightly above the lower end of the corner plate 10. In this case, since the corner plate 10 can be brought into close contact with the stack T with the two binding belts, the stack T can be securely bound even in the case of a multi-stack stack T.
[0017]
Next, the shape of the insertion plate 20 will be described.
FIG. 2 is a plan view of the load collapse prevention device 1 of the present embodiment. As shown in the figure, the insertion plate 20 is a right-angled triangular plate material, and both sides sandwiching the right angle are fixed inside the corner plate 10.

Can be.
The insertion plate 20 may be not only a right triangle plate but also a square plate. In this case, the vertex of the insertion plate 20 can be made to protrude outside the surface connecting the long edges of the plate members 11 and 12 of the corner plate 10, and the tip of the insertion plate 20 is sharp, so that the packing box m , M.
Furthermore, the insert plate 20 may be a quarter-arc plate. In this case, since the tip of the insertion plate 20 is round,
The packing box m can be inserted without damaging it.
[0018]
An anti-slip process such as a diamond cut is performed on the plate surface of the insertion plate 20. The non-slip processing may be performed on only the front surface, only the rear surface, or both the front and back surfaces of the insertion plate 20. By the non-slip processing on the plate surface of the insertion plate 20, the friction between the insertion box 20 and the packing box m can be increased, it becomes difficult to slip, and the load collapse prevention device 1 falls out of the gap between the packing boxes m and m. Can be prevented.
The non-slip processing is an optional matter, and the anti-slip processing does not necessarily have to be performed on the plate surface of the insertion plate 20.
[0019]
The insertion plate 20 is a right-angled triangular plate material, and the length of both sides sandwiching the right angle is formed to be shorter than the width of the plate materials 11 and 12 of the corner plate 10.
[0020]
For this reason, the oblique side portion of the insertion plate 20 can be provided inside the long edges of both sides of the corner plate 10, and the oblique side portion of the insertion plate 20 can be protected by both side portions of the corner plate 10, thereby preventing damage due to impact. can do.
Further, since the distance between the oblique side portion of the insertion plate 20 and the right-angled vertex can be shortened, the insertion can be easily performed, and the insertion operation can be performed in a short time.
Further, as shown in FIG. 2, a rail portion 13 in which the oblique side portion 14 of the insertion plate 20 intersects with the inner surface 15 of each of the plate members 11 and 12 can be formed. The vertex of the rail portion 13 can be moved up and down along the side of the packing box m, and the rail portion 13 can function as a guide, so that the insertion plate 20 can be inserted into the gap between the packing boxes m and m. The insertion plate 20 can be easily inserted.
In addition, in the insertion plate 20, the length of both sides fixed to the plate materials 11 and 12 may be equal to or longer than the width of the plate materials 11 and 12 of the corner plate 10. In this case, since the area for supporting the packing box m can be increased, the friction generated between the insertion plate 20 and the packing box m can be increased, and the insertion plate 20 can be prevented from falling out of the gap between the packing boxes m, m. .
[0021]
FIG. 4A is a sectional view of the insertion plate 20. As shown in the figure, the thickness of the insertion plate 20 is uniform.
[0022]
As shown in FIG. 4B, it is preferable that the insertion plate 20B be formed in a wedge shape. In this case, the insertion plate 20B can be easily inserted into the gap between the packing boxes m, m, and the portion to be attached to the corner plate 10 can be made thicker, so that it is robust and can be prevented from being damaged.
[0023]
Next, the belt passage hole 30 will be described.
3A is a sectional view taken along the line IIIA-IIIA of FIG. 1, and FIG. 3B is an enlarged view of a main part. As shown in FIGS. 1 to 3, one of the plate members 11 of the corner plate 10 is formed with a belt through hole 30 at an intermediate position in the longitudinal direction. The belt through hole 30 is for inserting the binding belt 2.
The binding belt 2 is not particularly limited as long as fixing means such as a sheet seal or a tackle is attached to the belt and both ends of the belt can be fixed by the fixing means. In particular, the use of the binding belt 2 having a tension belt attached to an end thereof is preferable because the tension belt can be grasped and pulled, and the stack T can be easily tightened. In addition, it is preferable to use the binding belt 2 having a hooking belt attached to an intermediate portion thereof, so that the hanging belt can be hooked on the packing box m to prevent the binding belt 2 from hanging down. .
[0024]
In addition, as shown in FIGS. 3A and 3B, the belt through hole 30 is inclined from the side end of the plate 11 toward the connecting portion from the back side of the plate 11 toward the front side. Is formed. The inside inclined surfaces facing each other in the belt through hole 30 are indicated by reference numerals 31 and 32.
[0025]
The inner inclined surfaces 31 and 32 of the belt through hole 30 are inclined so as to approach from the side end of the plate material 11 to the connecting portion from the back side of the plate material 11 toward the front side. The binding belt 2 can be easily inserted into the belt through hole 30 because it can be inserted into the through hole 30.
In addition, since the friction between the binding belt 2 and the plate member 11 can be reduced, the binding belt 2 can be prevented from being damaged by friction.
[0026]
The binding belt 2 can be attached to the corner plate 10 by inserting the binding belt 2 into the belt passing hole 30. Moreover, the binding belt 2 can be pulled out from the inside of the plate member 11 of the corner plate 10 to the outside through the belt through hole 30 and can be brought into contact with a part of the outer surface of the plate member 11 and the outer surface of the plate member 12. By tightening 2, the aggregate T can be bound by the corner plate 10.
[0027]
In addition, as shown in FIGS. 1 to 3, since the belt through hole 30 is formed only in one plate member 11 of the corner plate 10, the binding belt 2 is passed through one belt through hole 30. It is only held down at this part. For this reason, when the binding belt 2 is tightened, the binding belt 2 does not have a slack portion, and the binding effect can be enhanced.
[0028]
FIG. 7 is a plan sectional view of the integrated body T in FIG. As shown in FIGS. 3, 6 and 7, four unloading prevention devices 1 were attached to the binding belt 2 in advance, and then each unloading prevention device 1 was attached to each of the four corners of the stack T of the packing box. Later, the binding belt 2 is wound around the stack T of the packing box, the binding belt 2 is tightened, and both ends are fixed by the fixing means of the binding belt 2, so that the stack T can be bound.
After attaching the four cargo collapse prevention devices 1 to the four corners of the stack T of the packing box, the binding belts 2 are sequentially passed through the belt passing holes 30 of the corner plate 10 in each of the cargo collapse prevention devices 1, and then the binding is performed. Both ends of the belt 2 may be fixed.
