Description

  The present invention relates to a load collapse prevention device that can prevent an article loaded on a pallet from collapsing.

In order to prevent the goods loaded on the pallet from collapsing, a method of wrapping the goods with a film has been widely used. And the problem that the handling of the film (especially the packaging operation of the article) is troublesome.
In order to solve this problem, after wrapping a packaging material around the article, the packaging material is inflated with air to increase the tightening force (fixing force) on the article, and the packaging material (article) used in this method Packaging fixtures) have been proposed (see Patent Document 1). This packaging material is formed so that a plurality of elongated airtight chambers (air chambers) are arranged in the same direction by dividing the winding direction around the outer periphery of the article with a fine pitch.

Note that hook-shaped locking means for hooking onto the pallet is attached to the lower end portion of the packaging material, and position locking on the pallet is prevented by this locking means.
Japanese Patent Laid-Open No. 2004-99070

The above-described conventionally known packaging material (Patent Document 1) is in a soft state (a state of abundant flexibility) without air before blowing in air, and in that sense, is different from cloth or a resin sheet. There is nothing. For this reason, the operation of winding such a soft packaging material around the article on the pallet is very troublesome, and it is extremely difficult to carry out the work alone.
In addition, air blowing naturally requires equipment (such as a compressor) to be a supply source of compressed air, and there is a big problem that the place of use is limited. This means that, for example, when an article is transported by truck in a palletized state, the loading place on the truck is limited.

Furthermore, the packaging material needs to have a double-sided structure (so that air can be stored) in order to form an airtight chamber, and the structure itself is expensive and heavy and thick. There was also a problem that hindered the above.
In addition, this packaging material is fixedly supported by one worker with the hand at the beginning of winding on an article loaded on the pallet, and the other worker holds the other end of the packaging material on the pallet. There is also a problem that it is necessary to wind around the article and fix it with a fastening tool, which requires at least two workers.

  The present invention has been made in view of the above circumstances, and can be operated by one person in an unloading prevention apparatus used to prevent unloading of articles loaded on a pallet. It is an object of the present invention to provide a load collapse prevention device that is free of restrictions and has a low cost.

In order to achieve the above object, the present invention has taken the following measures.
That is, the load collapse prevention device according to the present invention includes a belt-like sheet that can be wound around the outer periphery of an article loaded on a pallet, a support provided at one end in the longitudinal direction of the sheet, and the support. A support leg member which is provided at the lower end of the pallet and can be engaged with the outer peripheral part of the pallet and which can hold the column upright in this engaged state, and both ends in the longitudinal direction in a state where the sheet is wound around the article And a tightening means that makes it possible to hold the tightening.
With such a configuration, the support leg member can be engaged with the pallet, whereby the support column can be erected in an independent state with respect to the pallet. Then, the sheet can be wound around the article loaded on the pallet with the support column as a starting end.

That is, for this reason, the sheet can be wound around the article by one person. Moreover, since one sheet of normal sheet material can be used for the sheet, and a double-sided structure is not necessary, the cost can be reduced. Of course, since there is no need for a facility for supplying compressed air, there is no restriction on the place of use.
The support leg member is provided in a laterally projecting state so that it can be inserted into a fork insertion port formed on the side surface of the pallet, and the upper part of the lateral projection is in contact with the inner upper surface of the fork insertion port. An upper engagement surface is formed, and a lower engagement surface that is in contact with the inner lower surface of the fork insertion port may be formed on the lower portion in this lateral projecting state.

If the support leg member is engaged using the fork insertion port of the pallet in this way, the contact of the support leg member with the pallet is not affected by contact interference with the article on the pallet. It becomes possible.
The support leg member has an upper leg piece with the upper engagement surface formed on the upper surface and a lower leg piece with the lower engagement surface formed on the lower surface, and these upper leg piece and lower leg piece. It is good also as what has the elastic member which elastically presses both pieces to the up-and-down-separation direction relatively between upper and lower.
By doing in this way, engagement of the support leg member with respect to the fork insertion port of a pallet is ensured. In addition, even if there is some variation in the vertical opening size at the fork insertion port of the pallet, the vertical distance between the upper leg piece and the lower leg piece is automatically adjusted by the elastic pressing force of the elastic member, and the result The support leg member can be engaged with the pallet.

The support leg member has an upper leg piece with the upper engagement surface formed on the upper surface and a lower leg piece with the lower engagement surface formed on the lower surface, and at least one of the upper and lower leg pieces. May be provided so as to be movable up and down, and a leg piece fixing means for fixing the height position after the movement may be provided on the leg piece that is movable up and down.
This also ensures the engagement of the support leg member with the fork insertion port of the pallet. In addition, even if there is some variation in the vertical opening size at the fork insertion port of the pallet, if the vertical distance between the upper leg piece and the lower leg piece is appropriately adjusted, and fixed by the leg piece fixing means, The support leg member can be engaged with the pallet.

It is preferable that the sheet is provided with the second support column in a state parallel to the support column with respect to the end portion in the longitudinal direction on the opposite side to the support column.
In this way, the band width of the sheet (the shape expanded in the vertical direction) is held by the second support column, so that handling becomes easy and winding work on the article becomes easy.
The second support column may be provided with a handle for rotating the second support column when the sheet is wound and collected around the second support column.
By doing so, it becomes easy to wind up and collect the sheet.

  The load collapse prevention device according to the present invention can be operated by one person, is easy to handle, has no restrictions on the place of use, and is low in cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
1 to 5 show a first embodiment of a load collapse prevention device 1 according to the present invention. The load collapse prevention device 1 is provided on a belt-like sheet 2, a support column 3 provided at one end portion in the longitudinal direction of the sheet 2, a support leg member 4 provided at a lower end portion of the support column 3, and the sheet 2. The tightening means 5 is provided. Further, the load collapse prevention device 1 has a second support column 6 provided at the other end of the seat 2.

The sheet 2 can be wound around the outer periphery of the article W loaded on the pallet P, and can be formed of a resin sheet such as vinyl or PP, or a cloth. Of course, selecting materials that are superior in terms of durability, high strength, etc., as well as waterproofness, breathability, fungicidal properties, weather resistance, fire resistance, etc. is also a matter to be considered as necessary.
In order to hold the support column 3 and the second support column 6 at both longitudinal ends of the sheet 2, it is convenient to form a bag portion 10 penetrating vertically by sewing or bonding.
Note that the band width (height dimension during use: hereinafter referred to as “height”) and length of the sheet 2 may be appropriately determined according to the size of the pallet P or the article W to be used. For example, since the general pallet P has a side of about 1000 to 1100 mm, the length of the sheet 2 may be 4000 to 4400 mm. The height may be 1200 to 1500 mm.

Of course, since it does not have to match the size of the pallet P or the article W, some size is acceptable, and in some cases, it may be used in common for several sizes. .
The support column 3 is a portion that becomes a core (shape-retaining material) when the sheet 2 is erected along the outer peripheral portion of the pallet P, and is formed with a length substantially corresponding to the height of the sheet 2.
In the first embodiment, the two round bar materials 11 are made parallel to each other and connected at appropriate positions in the longitudinal direction by the connecting plate 12. The round bar material 11 may be made of metal or resin. In some cases, the round bar material 11 can be made of wood.

As shown in FIG. 4, the support leg member 4 can be engaged with the outer peripheral portion of the pallet P, and is directed from the lower end portion of the support column 3 to the fork insertion port h formed on the side surface of the pallet P. So that it can be inserted.
In the support leg member 4, the upper portion in the laterally protruding state is formed as an upper engagement surface 15 that contacts the inner upper surface of the fork insertion port h. Further, the lower part in the lateral projecting state is formed as a lower engagement surface 16 that comes into contact with the inner lower surface of the fork insertion port h.

The upper engagement surface 15 and the lower engagement surface 16 contact the inner upper surface and the inner lower surface of the fork insertion port h at the same time when the support leg member 4 is inserted into the fork insertion port h of the pallet P. The upper engagement surface 15 presses the inner upper surface upward and the lower engagement surface 16 presses the inner lower surface downward.
For this reason, the support leg member 4 is engaged in the fork insertion port h without any backlash, and the support column 3 is held upright above the support leg member 4. If the support leg member 4 is pulled out from the fork insertion port h with motivation, the engagement force is such that the support leg member 4 can be pulled out relatively easily.

In the first embodiment, the support leg member 4 is formed integrally with the support column 3 and the support leg member 4 by bending the lower end portion of the round bar material 11 forming the support column 3 into a U shape. It is like that. In consideration of ease of insertion into the fork insertion port h of the pallet P, the upper engagement surface 15 has a lower height so that the height of the support leg member 4 is slightly smaller toward the tip protruding laterally. A downward inclination and an upward inclination are given to the lower engagement surface 16.
The second support column 6 is provided in a state parallel to the support column 3 with respect to the longitudinal end portion on the opposite side to the support column 3 in the seat 2. Since the height of the sheet 2 is also maintained by the second support column 6, the handling of the sheet 2 is facilitated, the sheet 2 is wound around the article W, and then the sheet 2 is removed from the article W. The removal work can be easily performed.

Note that a handle 20 is provided at the upper end of the second support column 6. The handle 20 has a grip portion 20a that protrudes upward. The grip portion 20a is disposed in a state of being bent in a crank shape with respect to the second support column 6 (from the axis of the second support column 6). It protrudes upwards at a shifted position).
Therefore, when the grip 20a is turned around the axis of the second support column 6 as a fulcrum, the seat 2 can be wound around the second support column 6 as an axis. That is, when the sheet 2 wound around the article W is subsequently removed, if the sheet 2 is peeled off from the article W while turning the handle 20, the sheet 2 is wound around the second column 6 and collected. Can do.

Therefore, the sheet 2 removed from the article W can be collected in a compact manner, the subsequent handling is easy, and the sheet 2 can be easily reused (wrapped around the article W). Of course, there is an advantage that these operations can be performed alone.
When the sheet 2 is wound around the article W (see FIG. 2), the winding means 5 is for holding the both ends of the sheet 2 in the longitudinal direction. The specific structure is not particularly limited, but it is necessary that the structure can be used repeatedly.
In the first embodiment, a flexible string-like member 21 is provided on one end side in the longitudinal direction of the sheet 2, and a ring member 22 through which the string-like member 21 is passed is provided on the other end side in the longitudinal direction of the sheet 2. The string-like member 21 and the ring member 22 can be connected and separated. In the example shown in the drawing, the combination of the string-like member 21 and the ring member 22 is provided at three positions in the upper and lower directions, but the number of installations and the arrangement are not limited at all.

The string-like member 21 can be formed by a resin belt such as nylon. In addition, it may be made of cloth, leather, metal (such as a chain), or the like. The ring member 22 is also preferably attached to the seat 2 via a resin belt 23 or the like.
As shown in FIG. 5, the string-like member 21 and the ring member 22 are connected by inserting the string-like member 21 into the two ring members 22 and turning them back, and then turning the folded end portions of the two ring members. It is possible to adopt a structure in which it is locked and held in a tightened state by being pulled out through one of them.

In addition, although illustration is abbreviate | omitted, it is also possible to employ | adopt the connection structure etc. by the belt and belt loop which are often used with clothing (trousers etc.).
As is apparent from the above description, in the load collapse prevention device 1 of the present invention having the above-described configuration, as shown in FIG. 3, the column 3 is attached to one longitudinal end portion (the wide-mouthed bag portion 10) of the seat 2. And the second support column 6 is inserted into the other end in the longitudinal direction of the sheet 2 (narrow bag portion 10). You may fix these support | pillars 3 and the 2nd support | pillar 6 in the state inserted in each bag part 10. FIG.

Then, as shown in FIG. 1, the support leg member 4 is inserted into and engaged with one of the fork insertion ports h with respect to the pallet P in which the articles W are loaded. Thereby, the support | pillar 3 is hold | maintained in the standing state in the outer peripheral part of the pallet P. FIG.
Next, as shown in FIG. 2, the sheet 2 is wound around the article W on the pallet P with the column 3 as a starting point. At this time, if the second support column 6 is gripped, the winding operation can be performed while the sheet 2 is expanded, so that the operation is easy.
In a state where the sheet 2 is wound up to the standing position of the support column 3, the winding fastening means 5 is brought into a connected state (see FIG. 5). Thus, the winding operation of the sheet 2 around the article W can be performed by one person.

As described above, since the area around the article W is wound and fixed by the sheet 2, there is no possibility that the article W will collapse due to conveyance vibration or the like.
[Second Embodiment]
6 and 7 show a second embodiment of the load collapse prevention device 1 according to the present invention. The place where the load collapse prevention device 1 of the second embodiment is most different from the first embodiment is that the support leg member 4 provided at the lower end of the support column 3 has an upper leg piece 30 and a lower leg piece 31. In addition, a resilient member 32 is provided between the upper and lower leg pieces 30 and 31.

These left and right side rods 41 come into contact with the side surface of the pallet P together with the support column 3 when the support leg member 4 is inserted into the fork insertion port h of the pallet P (see FIG. 7). Therefore, a three-point support state in which the left and right side rods 41 are in contact with the left and right sides of the column 3 with respect to the side surface of the pallet P is obtained. Therefore, it leads to the advantage that the stability of the engagement state of the support leg member 4 with respect to the pallet P and the stability of the standing state of the column 3 can be obtained.

The lower leg piece 31 is fixed to the support column 3 by welding or the like.
The resilient member 32 is for elastically pressing the upper leg piece 30 and the lower leg piece 31 relatively in the vertical direction. In the second embodiment, the elastic member 32 is formed by adopting a plate spring in which the upper and lower spring plate portions 32a and 32b are bent in a "<" shape when viewed from the side. Engaging protrusions 42 project from the elastic member 32 so as to protrude rearward from the upper and lower spring plate portions 32a and 32b.
On the other hand, the support 3 is provided with an upper engagement hole 43 that can be engaged with an engagement protrusion 42 provided in the upper spring plate portion 32a, and an engagement provided in the lower spring plate portion 32b. A lower engagement hole 44 that can be engaged with the protrusion 42 is provided.

Among these, the upper engagement hole 43 is a long hole that is long in the vertical direction, and the lower engagement hole 44 is a short round hole or a square hole in the vertical direction.

In general, many products are distributed), or when there is some dimensional variation.
That is, the set bolt 40 provided on the support leg member 4 is loosened in advance, and the vertical distance between the upper leg piece 30 and the lower leg piece 31 is narrowed against the elastic force of the elastic member 32. Accordingly, the set bolt 40 is temporarily tightened in this state. Then, after the support leg member 4 is inserted into the fork insertion port h, the set bolt 40 is once again loosened.

By doing so, the vertical distance between the upper leg piece 30 and the lower leg piece 31 is widened by the action of the elastic member 32, and is automatically adjusted according to the vertical opening size at the fork insertion port h. Will be. That is, the support leg member 4 can be reliably engaged with the fork insertion port h of the pallet P. Thereafter, the set bolt 40 may be tightened.
