In the case of individual pieces, 484 sandbags can be packed in the same manner, and a larger number of meshes 4a and support frames 3 can be prepared depending on the strength of the frame 4 and the capacity of a crane and other lifting devices.

Numeral 9 designates a plate-shaped soil receiving cover. The soil receiving cover 9 is provided inside each of the opening frames 2 so as to cover the outer peripheral side of the upper end of the support frame 3 and the gap adjacent to the opening frame 2 at the time of bag filling operation described later. A square insertion hole 11 is formed only at a portion corresponding to the circumference, and a rim-shaped guide 12 that is loosely inserted into the opening frame 2 is provided on the outer periphery of the insertion hole 11 so as to protrude downward. I have.

FIGS. 2 to 6 show the main components of the manufacturing apparatus and the detailed structure at the time of assembling. In this example, the supporting frame 3 firstly assembles the partitioning frame 1 and the opening frame 2 in the longitudinal direction and End plates 15a and 16a, which are composed of horizontal partition plates 15 and 16 and outermost partition plates (guide covers) 17, are welded to the lower ends of the respective partition plates 15 and 16 to partition the bottom of the support frame 3 in a mesh shape. And so on. And the end plates 15a, 16a
Are slightly projecting from the outermost ends of the peripheral wall portions 15c, 16c to form insertion engagement ends 15f, 16f into insertion grooves 4a formed on the inner periphery of the frame 4. At the lower end of the side cover 17, a peripheral wall portion 17c is extended to form an end plate 17c.
a is bent. The upper cross sections of the end plates 15a and 16a form an acute V-shape as shown in the figure, and are upwardly divided into two branches. Opening edges 15b and 16b forming the opening frame 2 are formed at the upper end thereof, and the lower part thereof is formed. Peripheral walls 15c, 16c that are slightly inclined inward toward the opening direction
It has become. The side cover 17 also has upper and lower end plates 17a.
(Peripheral wall portion) 17c between the opening 17b and the opening edge 17b is slightly inclined inward toward the opening.

The horizontal partition plate 15 has a V-shaped notch groove which conforms to the V-shaped cross section of the vertical partition plate 16 intersecting with the horizontal partition plate 15, and further has an end having the same width as the thickness of the end plate 16a at its lower end. A notch groove 15d, which is a notch groove having a depth of about 1/2 of the height width of the plate 16a, is formed, and each of the notch grooves 1 of a large number of horizontal partition plates 15 set in parallel at predetermined intervals.
By inserting the vertical partition plate 16 from the lower end side into 5d, a large number of vertical and horizontal partitions are assembled, and a large number of mesh-shaped opening frames 2 and the partition frame 1 are formed. At this time,
The other end plate 15a is also provided on the end plate 16a of the vertical partition plate 16.
a cut-out groove 16d for insertion into an end plate 15a opening downward is formed at the intersection with the end plate 15a.
Are assembled at the same height and cross each other.

The side covers 17 are assembled and fixed to the peripheral surface of the support frame 3 which is assembled as described above and has a square (or rectangular) shape as a whole. The stopper 6 described above is fixedly protruded from the outer periphery of the upper end by welding or the like. The end plate 17a is provided with a downward opening type cutout groove 17d through which the insertion engaging ends 15f and 16f projecting to the outer periphery of the support frame 3 are inserted.
Are formed.

Further, the side cover 17 is provided with a flange-shaped connecting portion 17f extending from the left and right or front and rear corner adjacent ends so as to fixedly form a peripheral wall of the support frame 3 which is square in plan view. It has a structure in which parts are detachably bolted together. As is apparent from the above-described structure of the partition plates 15 to 17, the support frame 3 in the assembled state has the peripheral walls 15c, 16c, and 17c forming a trapezoidal cylinder, but the opening frame 2 at the upper end and the end plate. 15a, 16a, 1
The frame portion 7a is a square frame portion that is straight in the vertical direction.

The opening edges 16b and 17b of the opening frames 2 in the support frame 3 are not continuous with those of the adjacent opening frames 2 (that is, each opening frame 2 is separated from the adjacent opening frames and independent meshes). Notches 16e and 17e are formed in the gaps adjacent to the opening frame 2).

Each of the adjacent gap portions of the opening frame 2 crossed vertically and horizontally in a mesh shape is formed at a lower end portion of the opening frame 2 (an upper end portion of the partition frame 1) by a corresponding mesh-shaped cover plate. 18 (having a hole 18a fitted to the outer periphery of the opening frame 2) is dropped and closed to be fitted. As a result, falling of soil or the like into the V-shaped groove between the adjacent partition frames 1 is prevented, and each partition frame 1 is prevented from falling.
Even at the upper end, it will be connected and fixed to the adjacent partition frame 1 with the accurate positioning and posture determined.

By the above-mentioned mechanism, the sandbag manufacturing apparatus is constructed so that both the support frame 3 and the frame body 4 can be disassembled and assembled, and each component is transported to the site in a disassembled state, and the site is assembled and after completion of the sandbag manufacturing operation described below. Has the advantage that it can be disassembled again and stored or transported.

However, for example, the support frames 3 are integrally fixed to the partition plates 15 to 17 and the cover plate 18 by welding or the like.
Alternatively, it is also possible to form the whole of the support frame 3 integrally, or to divide and mold the plastic frame, and combine them. If the strength of the support frame 3 is sufficient, the frame body 4 is not used. It is also possible to adopt a configuration in which the support frame 3 itself is directly lifted at the time of lifting and demolding after completion of bagging, which will be described later.

Next, a method for manufacturing a sandbag using the above apparatus will be described. As described with reference to FIGS.
For the device assembled on the frame 4 placed on the flat floor, as shown in FIG. 6, first, the sandbag 21 with the string 21a is attached.
Is inserted into the partition frame 1, and its open end is folded back together with the string 21a into the opening frame 2 which is the opening of the partition frame 1, and locked.
The soil receiving cover 9 is placed on the opening frame 2 to cover the gap between the adjacent partition frames 1 and press and fix the bag 21.

Next, for example, a shovel unit 2 such as a backhoe
The earth 23 such as soil and sand is dropped and supplied onto the upper surface of the support frame 3 by using 2 or the like, and the soil 23 is dropped into all the bags 21 while leveling the upper surface with a leveling rod 24 or the like. Filling. By leveling with the leveling rod 24 or the like, the filling amount of the soil 23 into each bag 21 is made substantially uniform. On the other hand, the bag 21 is pressed and held along the inner peripheral wall of each partition frame 1 by the applied earth pressure.

Subsequently, after the soil receiving cover 9 is lifted or lifted by hand, the open end of each bag 21 is removed from the open frame 2 and the frame 4 is lifted using the wire rope 8 or the like. Is the support frame 3 as shown in FIG.
Is left on the floor in a state of being aligned along the grid of the square.

At this time, in order for each partition frame 1 of the support frame 3 to be smoothly lifted from the bag 21 and removed from the mold, it must be inclined in a pyramidal shape so as to have a small diameter upward as shown in the example. Further, it is desirable that the inner surface of the partition frame 1 and the peripheral surface of the bag 21 are coated so as to be slippery. If it is a slippery material such as a synthetic resin material, the partition frame 1 and the opening frame 2
May have a straight cylindrical shape, or may be a cage type formed by a vertical lattice without being limited to the cylindrical shape.

As shown in FIG. 7, the bags 21 arranged as described above are drawn in a line or in each divided block, or the strings 21a of all the arranged bags 21 are pulled out to narrow the bag opening. The looped string 21a is suspended at predetermined intervals by a beam 26 or a lifting body 27 composed of a frame, which is locked by a hook 26, and is transferred to a transporting means such as a truck or a freight car or transferred to a predetermined location. .

The sandbags 21 arranged in this manner and conveyed to the construction site in the aligned state are again lifted line by line by the lifting body 27 or the like, unloaded to the construction position, and finally repositioned. It is also possible to perform stacking work alone.

According to the above-described method, there is an advantage that the operation from bag filling to transport, unloading and sandbaging can be carried out without the heavy labor of directly carrying and lifting the sandbags 21 by hand, as well as a backhoe or shovel. If you use a construction machine that has the function of dropping and supplying earth to sandbags, such as heavy machinery, and the function of lifting luggage, you can use a single machine generally used in civil engineering construction sites to convert from bagging to loading. When bagging is performed at a loading operation or a civil engineering work site, there is an advantage that the operation from the bagging operation to the sandbag operation can be performed.

Incidentally, in the conventional case where bagging is performed manually only, the bagging amount per person per day is limited to several tens of bags, and even if a machine such as a conveyor is used, the limit is several times the limit. According to the method and apparatus of the invention, thousands of bags can be packed per day, and there are great advantages in cost and efficiency.

[0034]

According to the present invention having the above-described structure, the operation is quick and efficient, and requires less labor and a great deal of labor than conventional sandbag manufacturing operations. There is an advantage that cost reduction can be realized. In addition, since the device can be assembled and disassembled, transportation or storage is convenient, site work such as a civil engineering site having poor traffic conditions is facilitated, and it is particularly useful for emergency work in a disaster area or the like.
