Description

  The present invention relates to a sandbag filling device used for filling a sandbag with a filler such as earth and sand, and a sandbag filling method using the sandbag filling device.

When making sandbags to be used in disasters, etc., work is performed to manually fill the sandbags with fillers such as earth and sand.
Usually, this work is performed by a pair of a person in charge of opening the mouth of the sandbag and a person in charge of throwing sand and sand into the sandbag with a scoop.
In this case, the person in charge of opening the mouth of the sandbag spreads its mouth by holding the mouth edge of the sandbag with both hands. It is difficult to take big. For this reason, it has been difficult for a person in charge of earth and sand to quickly and suitably throw in earth and sand. Therefore, a great deal of labor was required when it was necessary to make a lot of sandbags in the event of an emergency such as a flood, typhoon or landslide.
In addition, when working in a hurry, the tip of the scoop hits the arm or hand of the person in charge of opening the mouth of the sandbag, which could cause injury.

On the other hand, when putting earth and sand etc. in a sandbag, the method which attaches a receiving hopper and puts a cylinder in a sandbag makes it easy to put earth and sand (refer patent document 1).
In this method, the sandbag is lifted up to the upper mouth so as to wrap from the lower mouth of the cylinder, and sand and the like are introduced through the receiving hopper, and then both hands are put on a pair of clue holes provided on the upper side of the cylinder. By pulling out the cylinder, it is filled with earth and sand.
Another idea is a work table, a sandbag support frame, and a funnel (hopper). A cylindrical sandbag support frame with openings on the top and bottom of the work table has a large diameter lower support frame opening. There has been proposed a sandbag production stand having a structure in which a hopper is put on a support frame upper opening having a small diameter and sandwiching an upper edge opening of the sandbag with a hopper (see Patent Document 2).

Specifically, the lower edge 12c of the frame main body 12 is flat and is configured by four side wall plates 15 having the same shape with the trapezoid turned upside down. By forming the hopper shape in this way, the opening on the top surface (top surface) is made wider than the opening on the bottom surface entering the mouth of the sandbag so that it is easy to put in a filler such as earth and sand. Can do. Moreover, since the inner surface of the side wall plate 15 is an inclined surface, the filler can be suitably dropped and packed into a sandbag. Furthermore, since it is formed in a hopper shape, that is, in a tapered shape, a large number can be suitably stacked and stored.

The shape of the frame main body 12 is not limited to the embodiment shown in FIG. 1, and various forms are conceivable for achieving the function.
For example, the present invention is not limited to the rectangular frame shape as shown in FIG. 1, and the same function can be achieved even in a funnel shape in which the truncated cone shape is inverted. Furthermore, even if it is not a hopper shape, for example, even if it is a rectangular parallelepiped (square tube) frame main body or a cylindrical frame main body that is open at the top and bottom, a filler such as earth and sand is suitably guided to Can be packed in a bag. Moreover, it is not limited to a rectangular frame shape, and may be another polygonal frame shape.

Reference numeral 20 denotes a handle portion, which is an outer surface portion of the side wall plate 15 of the frame main body 12 and is provided in the middle portion of the side wall plate 15 in the vertical direction. At least a pair of the handle portions 20 is provided for lifting. Thus, since the handle part 20 is provided in the outer surface part of the side wall board 15 of the frame main body 12, although it is a kind of clue part, it does not become a form of the through-hole which a filler leaks.
Moreover, it is good for this handle part 20 to be provided below the intermediate position of the frame main body 12 in the up-down direction. Further, the handle portion 20 may be provided in the vicinity of the intermediate position in the vertical direction of the frame body 12. That is, when inserting the appropriate portion of the lower side 12b of the frame body 12 into the mouth of the sandbag, the height of the handle portion 20 is set so as not to obstruct the filling of the sand and sand with good workability. You can pack things. If the handle portion 20 is excessively provided on the lower side, it is difficult to pull up the mouth of the sandbag and the mouth is easily detached from the frame body 12, so that the handle portion 20 is easy to set the mouth of the sandbag. It may be provided on the lower side.

  This is because the sandbag filling method of the present invention, which will be described later, has an advantage that the sandbag filling device 10 can be easily set by simply inserting the frame body 12 into the mouth of the sandbag. Furthermore, when the position of the handle part 20 is set as described above, there is also an advantage that the sandbag filling instrument 10 can be suitably lifted in a stable and easy-to-balance state. When the handle portion 20 is provided near the upper edge 12a of the frame body 12, the scoop is easy to contact. When the handle portion 20 is provided near the lower edge 12c of the frame body 12, the handle portion 20 is gripped. Since it becomes a difficult state, it is good to position it in the middle of the height direction.

In this embodiment, a pair of handle portions are provided on the pair of opposing side wall plates 15. The present invention is not limited to this, and the handle portions 20 may be provided on all outer surface portions of the four side wall plates 15.

More specifically, welding portions 24 that are bent at both ends of the U-shaped handle body 22 are welded and fixed onto the outer surface of the side wall plate 15 made of metal.
In addition, the shape of the handle part 20 is not limited to this, What is necessary is just a form which can lift the sandbag filling instrument 10 appropriately. Therefore, a protrusion-like form that can be simply hooked with a finger may be used, and as a form that can be hooked with a finger, a recess having an appropriate shape is provided on the outer surface of the side wall plate 15 so as not to prevent the falling of the filler. Also good. In addition, when it is the handle part 20 of the form protruded outward, there exists an advantage which can be set so that the edge part of the sandbag 50 (refer FIG. 12) may be hung.

Next, the folding structure of the sandbag filling instrument 10 according to the present invention will be described with reference to FIGS. 1, 6, 7 and 8 to 11.
1, 8 and 9 show an example in which the frame body 12 is composed of a plurality of members (side wall plates 15) and can be folded by hinges or the like.
These are polygonal shapes in which the frame main body 12 is in a state where a plurality of side wall plates 15 are connected in a loop shape. More specifically, the frame body 12 has a rectangular shape in which four side wall plates 15 are connected in a loop shape. The adjacent side wall plates 15 are connected to each other by a hinge 28 that is an example of a hinge, so that the side wall plates 15 can be folded.
By being comprised in this way, it can fold and store like FIG.6 and FIG.7. Since it becomes compact, there is an advantage that the storage space can be reduced.
Further, when the side wall plates 15 are connected to each other by the hinge 28, generally, some backlash occurs. By using the play to vibrate, there is an effect that sand attached to the inner surface of the side wall plate 15 can be dropped.

Although the material of the side wall board 15 which comprises the frame main body 12 is not specifically limited, Metal materials, such as stainless steel, are employable. 8 and 9, the reinforcing plate 18 is welded to the upper and lower portions of each side wall plate 15 to increase the rigidity of the plate.
However, the frame body 12 can be made of plastic. In that case, reinforced plastic (FRP) may be adopted, and a rib-like portion and a corrugated portion may be provided to improve rigidity and strength. Further, in order to make it foldable, it is possible to form a hinge portion by forming a thin-walled portion in a streak shape so that it can be folded. In the case of plastic molding, the handle portion 20 can be integrally molded relatively easily. According to this, manufacturing cost can be reduced.

Next, a shape retaining structure that retains the shape of the sandbag filling device in the folded state from the folded state will be described in detail with reference to FIGS.
As shown in FIGS. 8 and 9, engaged portions 31 and 32 are provided on the upper edge portions of the adjacent side wall plates 15 and 15 of the frame main body 12. In this embodiment, the engaged portions 31 and 32 are provided so that tunnel-like through holes 31a and 32a (see FIG. 10) that penetrate in the vertical direction are formed. The through holes 31a and 32a are formed so that the rod-shaped engaging portions 41 and 42 are fitted therein.
Reference numeral 40 denotes a shape-retaining metal fitting, which has an L-shaped metal fitting main body portion 40a so that adjacent side wall plates 15 and 15 are held in a perpendicular relationship, and is provided at both ends of the metal fitting main body portion 40a. Includes engaging portions 41 and 42 that engage with the engaged portions 31 and 32 provided on the side wall plate 15, respectively.
The single shape-retaining metal fitting 40 can be held in a rectangular shape with the planar shape of the frame body 12 shown in FIGS. According to this, although it is a simple structure, it can hold | maintain the shape of the implement for earthen filling suitably, and can manufacture it cheaply.

In addition, in the example of FIG. 8, one engaging part 41 is formed long, and the retaining part 43 is provided at the front-end | tip part.
According to this, the long rod-shaped engaging portion 41 is always inserted through the through hole 31a of one engaged portion 31, and does not fall off. In addition, by providing one engagement portion 41 long in this manner, the other short rod-shaped engagement portion 42 is operated by operating the shape-retaining metal fitting 40 with the one engagement portion 41 fitted. Is required to be engaged with or disengaged from the engaged portion 32, and there is an advantage that the operation can be easily performed.

Further, as shown in FIG. 9, the shape-retaining metal fitting 40 is normally biased by the spring member 45 so that the engaging portions 41 and 42 engage with the engaged portions 31 and 32 (see FIG. 10). When the spring member 45 is pulled up against the urging force (see FIG. 11), the engagement relationship between the engaging portions 41 and 42 and the engaged portions 31 and 32 may be released.
In this embodiment, a flat washer 47 disposed so as to contact the lower end of the engaged portion 31 with which the long rod-shaped engaging portion 41 is engaged, and a screw on the tip of the rod of the engaging portion 41. A coil spring which is a spring member 45 is disposed between the plain washer 47 disposed on the upper side of the combined nut 48. The two plain washers 47 and 47 and the coil spring 45 are in a state where the tip end side of the rod of the engaging portion 41 is inserted. Accordingly, the holding metal fitting 40 is normally positioned so that the other short rod-shaped engaging portion 42 is lowered to a position where it engages with the corresponding engaged portion 32.
According to this, the operativity which engages the engaging parts 41 and 42 with the to-be-engaged parts 31 and 32 improves, and it can hold | maintain the shape of the instrument for earthen filling suitably.

Next, based on FIG.12 and FIG.13, the sandbag filling method which fills the sandbag 50 with the filler 60, such as earth and sand, using the sandbag filling instrument 10 demonstrated above is demonstrated.
First, as shown in FIG. 12, the lower side 12b of the sandbag filling device 10 is placed in the mouth of the sandbag 50, and the sandbag filling device 10 is placed on the ground.
At this time, the sandbag filling instrument 10 may be inserted shallowly into the mouth of the sandbag 50, and the mouth edge 55 of the sandbag may hang on the handle portion 20. In other words, the bottom side of the sandbag 50 may be in a state where the wrinkles are overlapped and overlapped, and the sandbag filling device 10 may be set in a state in which the sandbag filling device 10 is raised. Therefore, it is not necessary to put the sandbag filling device 10 deeply into the sandbag 50 as in the prior art, and it can be easily set.

Next, as shown in FIG. 12, a filler 60 such as earth and sand is introduced into the inside of the earth filling device 10 (inner volume 16) with a scoop 62 or the like.
Then, as shown in FIG. 13, the sandbag 50 is held together with the sandbag filling device 10 by holding the mouthpiece 55 of the sandbag together with the pair of handle portions 20 provided on the sandbag filling device 10 with both hands 80 and 80. Raise the mouth.
Subsequently, the mouthpiece 55 of the sandbag is released and the sandbag filling device 10 is separated from the sandbag 50. The bottom of the sandbag 50 does not need to be lifted while being in contact with the ground, and may be released with the sandbag 50 extended moderately up and down. Since this operation can be easily performed in a series of operations, the filler 60 such as earth and sand can be quickly packed.
Finally, when the mouth strap 56 of the sandbag 50 is pulled and tightened and the mouth strap 56 is tied, the sandbag is completed.

  According to the above steps, the mouth of the sandbag 50 can be lifted together with the sandbag filling device 10 with an extremely light sensation, and the sandbag 50 can be reliably and suitably filled with a filler such as earth and sand. Exactly, the filler could be properly filled with the feeling that the earthen filling device 10 was lifted up without feeling the weight of the filler. That is, the resistance that the filling is caught by the soil bag 50 is not felt. This is because the sandbag filling device 10 guides the falling of the filling material, and when the lip 55 is pulled up so that the sandbag 50 rises, the sandbag 50 itself continues to drop the filling material. It is thought that it can guide suitably. It can also be said that the filling material moves smoothly and can be suitably filled in the soil bag 50 without reducing the energy of dropping of the filling material due to gravity.

Further, according to the present invention, as shown in FIG. 12, a line or the like serving as a scale 70 is attached so that the amount of the filler 60 put into the inner surface of the frame body 12 (the inner surface of the side wall plate 15) can be seen. Then, the operator only has to put the filler 60 as a mark. According to this, it is possible to efficiently make a sandbag having a uniform size and weight.
Furthermore, by providing a plurality of scales 70, it becomes possible to uniformly fill the filling corresponding to the sandbags 50 of various sizes.

  In addition, this earthenware filling instrument 10 is not limited to the case where earth and sand are packed in a bag as in this embodiment, but can also be applied to the case where other general fillers are manually packed in a bag. For example, if a filling device equivalent to the sandbag filling device 10 is used, an operation of packing a granular material such as grain or a powdery material into a bag can be performed efficiently.

  The present invention has been described above with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.
