BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bagging machine used for bagging sand or similar crushed stone powder.

[0002]

2. Description of the Related Art Sandbags as sandbags are sometimes used in emergency civil works and simple civil works in disaster areas, but the production of these sandbags is often done manually with a scoop or the like. Is labor-intensive and inefficient. As a means to carry out this mechanically and continuously, Shokai 61
There is a proposal for a sand filling device of -86201.

[0003]

In the above-mentioned sand filling device, since the structure of the sand measuring mechanism and the mechanism for supplying the measured sand into the bag are complicated, it is difficult to maintain them. Besides, there is a problem that the manufacturing cost is high. An object of the present invention is to provide a bagging machine for sand and the like, in which such problems are solved.

[0004]

In order to achieve the above object, the present invention provides a vertical axis which can be freely rotated by power, and a sand tray is fixed to the vertical axis, and the vertical axis is set on the bottom surface of the sand tray. Through holes are provided on the circumference of the center, a cylindrical body of a fixed length is hung from each through hole, and a fixing plate for facing the lower end opening of the cylindrical body and closing the lower end opening is provided. At the same time, at least one discharge hole is provided at a fixed position of the fixing plate so as to face the lower end opening of the cylinder, and the lower end opening of each cylinder is formed at a position halfway down the vertical axis below the fixing plate. The chute which is faced is fixed, and a bag locking means is provided at the lower end opening of the chute, and a bag holder fixed to the vertical axis is provided below the chute. A raw material hopper is provided above the container. An opening height adjusting device is provided near the lower end opening of the raw material hopper.

[0005]

The raw material hopper is supplied with sand and the like inside, and the opening height adjusting cylinder makes it possible to appropriately supply the sand and the like in the raw material hopper to the sand tray to the required constant level. On the other hand, the vertical axis rotates the sand tray and the cylinder around the vertical axis. For this reason, the cylinder that has reached a specific position is supplied with sand and the like through the sand tray,
At this time, the upper surface of the sand or the like in the cylinder is the upper surface of the sand or the like supplied into the container. After that, the lower end opening of the cylinder to which sand or the like has been supplied successively reaches a position facing the discharge hole of the fixing plate, where the sand in the specific cylinder falls from the discharge hole and shoots it. Guides into the bag locked at the lower end opening. Thus, sand and the like are continuously packed in each bag, and thus the bags packed with sand and the like are successively removed from the chute, and the next empty bag is locked in the lower end opening of the chute instead. . The cylinder immediately above the chute with the empty bag attached is again supplied with sand and the like in the process of being rotated around the vertical axis, and thereafter, the same operation is repeated.

Eggplant

Numeral 24 is a bag holder for supporting the bottom of the bag n locked to the chute 19 and fixed to the vertical axis 4.

As shown in FIG. 6, the bag n used in the above-mentioned device has a string guide hole portion n1 formed along the upper opening thereof, and the upper opening of the bag n is opened by pulling the string r inserted therethrough. It is supposed to be squeezed.

Next, an example of use of the above apparatus and its operation will be described. By operating the bolts 13 or 14 prior to the start of the work, the cylinder body 11 of the opening height adjusting cylinder 10 or the shutter 12 is vertically displaced to set its position to the optimum position. On the other hand, sand or the like is put into the raw material hopper 9 with a power shovel or the like. The sand and the like may be crushed stone powder generated in a quarry, and the crushed stone powder is obtained by sieving a crushed stone group. Thus, the sand or the like thrown into the raw material hopper 9 is dropped to a certain level in the sand tray 15 through the opening height adjusting cylinder 10 by the action of gravity. After that, a switch (not shown) is operated near the bag support 24 to rotate the motor M to rotate the vertical axis 4. At this time, the rotation speed of the vertical axis 4 is adjusted by operating the continuously variable transmission T. When the vertical axis 4 is rotated in this way, the sand tray 15, the cylindrical body 16 ...
.., chute 19 ... And bag cradle 24 are rotated, but in this process, each cylinder 16 ... is positioned immediately below the opening height adjusting cylinder 10 and sand is inwardly there. And so on. The upper surface of the sand and the like in the cylindrical body 16 at this time is the upper surface of the sand in the sand tray 15. On the other hand, the operator covers the lower opening 19a of each chute 19 with the upper opening of the bag n as shown in FIG.
By pulling both ends of the rod and squeezing the upper opening
The cord r that is pulled up by the bulge is locked by the handle cam body 22 and the rod body 2 as shown in FIG.
1 and then swinging the cam body 22 to a position indicated by an imaginary line to lock the cord r so as to be sandwiched between the peripheral surface of the cam body 22 and the rod body 21. . When the vertical axis 4 is further rotated under this condition, the tubular body 16 after the sand or the like has been supplied is finally positioned directly above the discharge hole 18a of the fixing plate 18, and the sand inside the tubular body 16 is located here. Such as discharge hole 1
It is dropped toward the chute 19 located immediately below it through 8a, and then dropped into the bag n locked by the chute 19. In this way, the bag n supplied with sand or the like is further rotated together with the bag receiving table 24, and when it reaches a predetermined position, the operator operates the cam body 22 with the handle to remove it from the chute 19 and receive the bag. Stand 2
4 to another place, and instead, the chute 19 is locked with an empty bag n at its lower end opening by the same procedure as described above. In this way, the cylindrical body 16 after sand etc. is discharged
Is rotated about the vertical axis 4 so that its lower end opening is closed by the fixing plate 18 and is positioned immediately below the opening height adjusting cylinder 10 again to be supplied with sand or the like. Similarly, it is similarly discharged again at the position of the discharge hole 18a. This operation is similarly repeated for each cylinder, so that bagging with sand or the like is performed mechanically and continuously.

When the amount of sand or the like in each bag n is changed in the middle of the work, the position of the cylinder 11 or the shutter 12 is moved up and down by operating the bolts 13 or 14 of the opening height adjusting cylinder 10. I will let you. When the cylindrical body 11 or the shutter 12 is displaced upward, the container 1
5, the level of sand or the like supplied to the inside of the tubular body 16 rises, the upper surface of the sand or the like inside the cylindrical body 16 rises, and the amount of sand or the like supplied from the discharge hole 18a into the bag n increases. When the cylinder 11 or the shutter 12 is displaced downward, the level of sand or the like supplied into the sand tray 15 is lowered and the cylinder 16
The upper surface of the sand and the like inside is lowered, and the amount of sand and the like supplied into the bag n is reduced contrary to the above. Therefore, when the opening height is appropriately adjusted by the opening height adjusting cylinder 10, a desired amount of sand or the like is dropped into the bag n.

If the rotation speed of the vertical axis 4 is appropriate during the work, the sand filling can be carried out while the motor M is continuously rotated, but if the bag n cannot be removed or attached in time, a switch (not shown) is operated. The motor M is temporarily stopped.

Although four cylinders 16 are provided in the above embodiment, the number of cylinders 16 is not limited to four. Also, the opening height adjusting cylinder 10
It is also arbitrary that the bag holding means k is different from that of the above embodiment.
