FIG. 11 shows a kneading pressurizing pump (material kneading device) disclosed in Japanese Patent No. 2610340, in which a mixing pipe 1 is disposed at an angle of 10 ° to 15 ° with respect to a horizontal plane and is somewhat inclined downward. And a funnel container (hopper) 2 for accommodating a building material.
It can be cut off from.

[0003] A rubber worm 5 is arranged in the mixing pipe 1 adjacent to the inlet opening 4, and supplies the building material into the mixing chamber 6 by the rubber worm 5. The mixing chamber 6 is provided with one or more mixed water nozzles 8 and a stirrer 14 for kneading the material with water. Mixing tube 1
An eccentric worm pump 10 is fixed to a flange 9 formed at the end of the eccentric worm pump. The eccentric worm 10a of the eccentric worm pump 10 is driven by a motor 11 via a number of shafts divided by joint connection. A first joint 12 is provided between the motor 11 and one end of the rubber worm 5, and a second joint 13 is provided between the other end of the rubber worm 5 and one end of the stirrer 14. A third joint 15 is provided between the other end and the eccentric worm 10a. The eccentric worm 10a is operated at a relatively low rotational speed in the range of, for example, 160 to 200 rpm to transport the kneaded material in the direction of the discharge port 10b.

The stirrer 14 has a longitudinal axis 16 shown in FIG. 12 and is provided with substantially two scraping rods 17. The scraper bar 17 is used to peel off or prevent the accumulation of material in the peripheral area of the mixing chamber 6 and extends parallel to the longitudinal axis 16 and has a substantially square cross section. .

The mixing water nozzle 8 cooperates with an automatic actuator for mixing water administration (not shown), so that a predetermined amount of water and material injected in the mixing chamber 6 are mixed, and thereafter the water and the water are mixed. The mixed material is further pumped by the eccentric worm 10a, sent to the discharge port 10b, and discharged from the discharge port. Therefore, the kneading material can be sprayed or driven by attaching a blowing device or a driving device to the discharge port 10b.

[0006]

The material kneading apparatus as described above is used for bagged dry mix material (usually 20 kg).
Are put into the hopper 2 one by one, kneaded with water supplied by a predetermined amount, and discharged. The reason why the bag has a predetermined amount is that the dry mix material can be kneaded one batch at a time using a normal mortar mixer without using the kneading device. As mentioned above,
In the prior art, bagged materials of about 20 kg are put into the hopper 2 one by one. For this reason, when a large amount of fixing material must be cast at one time, the dry mix material must be continuously supplied by hand throughout the entire process, and the dry mix bags are opened one by one and placed in a hopper. It had to be put in, so it was very complicated. In addition, there is a problem in that a large amount of empty bags of material come out after the work is completed, and this must be disposed of. In this case, since powder such as cement adheres to the inside of the empty bag of material, even if the empty bag is collected, it is difficult to regenerate the empty bag, and disposal or incineration is required, but there is a problem of environmental pollution. Occurs. Furthermore, each time the dry mix material is opened and charged, dust is generated from the bag, and while the material kneading and casting work is continuous, workers are continuously involved in this work. Consideration was also required for labor reduction and safety and health measures for workers.

As described above, an object of the present invention is to significantly reduce the labor required for opening a bag and putting a dry mix material into a hopper, to reduce the labor of an operator, and to provide a material mixing apparatus and a material supply in consideration of safety and health measures. Is to provide a bag. Another object of the present invention is to provide a material kneading apparatus and a material supply bag which reduce the influence on the environment by repeatedly using the bag and filling the bag with a large amount of material. Another object of the present invention is to provide a material kneading apparatus which is effective for use in a special environment where a work space is small and a large amount of dry mix material cannot be stored, for example, in a tunnel. Another object of the present invention is to provide a material kneading apparatus capable of storing a large amount of material in a wet environment, for example, in a wet tunnel site, while maintaining a large amount of dry material.

[0008]

Bags do not come out, there is no problem of disposal (discarding, incineration) of empty bags, and the impact on the environment can be reduced. In addition, since the falling port formed into a cylindrical shape having a predetermined length completely enters the storage space of the tank and drops the material, the generation of dust when the dry mix material falls is minimized. Also, a tank for storing the material is arranged beside the kneading pump and the material is transferred in the lateral direction by the transfer means, so that the height of the material kneading apparatus can be reduced, so that the working space is narrow and the dry space is small. It is suitable for use in special environments where the mix material cannot be stored in large quantities, for example in tunnels. In addition, since a large amount of material is stored in a closed tank by closing the shutter, a large amount of material is stored while being kept in a dry state in a wet environment, for example, in a wet tunnel site. be able to. Also, with the lid of the tank opened, the material input jig is fitted into the material receiving port so as to be located in the material storage space of the tank, and when closing the tank lid, the jig is evacuated from the material receiving port. Therefore, the material supply bag can be stably held on the tank by the jig, and the falling port formed into a cylindrical shape having a predetermined length completely enters the storage space of the tank to drop the material. Therefore, generation of dust at the time of material falling can be minimized.

Further, the material supply bag of the present invention comprises: (1) a bag portion filled with a material, (2) a plurality of hanging bands attached to the bag portion, and (3) a bottom portion of the bag portion.

This bag 61 is not disposable and is used many times.
Tons of material are loaded. Then, when the dry mix material is put into the tank 54 from the bag 61, FIG.
The material charging jig shown in (c) is used. Material input jig 71
Is composed of a steel rod or the like, and is composed of two rings 71a and 71b and several straight rods 71c welded so as to hold the two rings 71a and 71b at predetermined intervals. A material dropping space 71d is formed inside the charging jig 71. The inner diameter of the lower ring 71b is formed corresponding to the size of the material receiving port 54d of the tank 54, and in the embodiment, is slightly larger than the diameter of the edge of the material receiving port 54d, while the upper ring 71a is formed. Is formed in a size corresponding to the outer diameter of the bag portion 61b of the bag 61 of the dry mix material. The jig 71 is used in a state in which the material is inserted into the material receiving port 54d with the lid 54e opened when the material is charged into the tank 54, and the material supply bag 61 is placed thereon (see FIG. 10). The material input jig 7 in the illustrated example
1 is separate from the tank 54 in a form in which the lid 54e is placed on the opened material storage space 54a at the time of the material input operation, and the jig 71 can be retracted from the lid 54e when the lid 54e is closed. If it is, it may be provided integrally with the tank 54. FIGS. 7 to 10 show the operation / primary stop of material supply to the hopper / interruption of operation, cleaning operation /
It is a state explanatory view of the material supply operation, and the same reference numerals are assigned to the same parts as in FIGS.

To perform the kneading and casting of the dry mix material, as shown in FIG. 7, one or two shutters 55 of the tank 54 filled with the dry mix material are opened, and the motor 60,
The screw pump 57 and the kneading pump 51
Drive. Then, the screw pump 5
The dry mix material MTR that has fallen to 7 is transferred as shown by the arrow, supplied to the kneading pump 51 via the hopper 52, kneaded with water, and discharged at a predetermined pressure. In this way, the amount of kneading and discharging (discharge amount per unit time) does not match the amount per unit time that the screw pump 57 transfers from the tank 54 into the hopper 52. This is a matter of course because the hopper 52 is provided because the discharge state of the kneading pump 51 changes sequentially. From the above,
If the discharge amount is small, the material accumulates in the hopper.

As shown in FIG. 8, a sensor 59 constantly monitors whether material has accumulated at the mouth of the hopper 52,
When the material accumulates at the mouth, this is detected and a warning signal ALM is input to a control unit (not shown). When the warning signal ALM is input, the control unit inputs a stop signal HLT to the motor 60 to stop the rotation. When the rotation of the motor 60 is stopped, the rotation of the bladed shaft (screw drive shaft) 57a of the screw pump 57 is stopped, and the transfer of the dry mix material MTR to the hopper 52 is stopped. This can prevent the material from overflowing from the hopper 52 even when the discharge amount is small. To restart the transfer by reducing the material in the hopper 52, the start switch is operated. In this case, it is also possible to set a lower limit storage amount for resuming the transfer, and control to automatically restart the transfer when the storage amount reaches the lower limit storage amount. When the operation is artificially interrupted, the supply of the dry mix material to the screw pump 57 is stopped by closing the shutter 55 of the tank 54. Even if the material kneading and casting operation is interrupted in this state, the dry mix material MTR is stored in a dry state inside the tank, so that it does not get wet and harden. Therefore, there is no waste.

[0017] Maintenance and stop working, to a cleaning operation or the like, a joint portion 57c, as shown in FIG. 9, remove both casing and bladed shaft only tip 57 _1. After removal, the maintenance of visual inspection and cleaning of internal casing remaining screw pump 57 _2. or,
Kneading pump side maintenance to do cleaning work, in a state in which removal of the distal portion 57 ₁ of the screw pump, a kneading pump 51 / hopper 52 fixed to the frame hanging on the crane is moved to another broad places, After the movement, maintenance work such as component replacement and internal cleaning of the kneading pump 51 is performed. In this way, maintenance and cleaning of the kneading pump 51 / hopper 52 can be performed in a place where the working space is wide. The maintenance and cleaning work of the kneading pump 51 / hopper 52 requires more work than the tank 54 and the screw pump 57, so that the effect is large.

The kneading and casting operation of the above materials is continued, and when it is confirmed from the viewing window that the amount of the material in the tank is low, the dry mix material is supplied. Fig. 1
As shown in FIG. 0, the lid 54e of the tank 54 is opened, and the material input jig 71 is attached to the edge of the material receiving port 54d by the lower ring 71b.
Are set so that they fit. Then, the material input jig 71
Is the storage space 54 of the tank 54 with the lid 54e opened.
a. Therefore, the bottom (see FIG. 6A) of the material supply bag 61 suspended by the crane 100 is made to face the material receiving port 54d, and the dry mix is dropped from the fall port 61c by the procedure shown in FIGS. 6B to 6E. The material MTR is dropped into the tank 54. That is, as shown in the bottom view in FIG. 6A, the bag 61 in a state where the material is loaded is in a state where the six bottom pieces 61h are squeezed by the string 61d,
In this state, when the string 61d is loosened, the bottom piece 61h opens as shown in FIG. 6 (b). Therefore, when the four pressing pieces 61g are opened as shown in FIG. 6 (c), the mouth is narrowed by the band 61f. In this state, the material drop port 61c stored in the bag portion 61b can be pulled out as shown in FIG. Then, if the band 61f is unwound, the material drop port 6
At this time, in the present invention, as shown in FIG. 6E, the bag 61 is placed on a jig 71 fitted into the material receiving port 54d of the tank 54. The material drop port 61c is arranged in the material dropping space 71d, and the band 61f is unfolded in this state. Then, the material supply bag 6
6 is stably held in the tank 54, the material drop port 61c pops out cylindrically as shown in FIG. 6E, and a new dry mix material MTR is supplied to the material receiving port 54d of the tank 54. From the storage space 54a (FIG. 10). Therefore, when performing the work of opening the bottom of the bag 61 containing the material MTR having a weight of as much as 1 ton, it is possible to prevent an operator from entering directly below the bag (the operator can work the material from between the straight rods 71c of the jig 71). Simply putting a hand into the insertion space 71d and pulling out the band 61f) naturally ensures high security. In addition, since the falling port 61c formed into a cylindrical shape having a predetermined length completely enters the storage space 54a of the tank 54 and drops the material, the generation of dust when the dry mix material falls is minimized. In addition, material supply is 1to
The process is performed every n minutes (50 times the amount of the conventional material), and the material supply bag 61 used for replenishment is repeatedly used, so that no empty bag is generated. Worker effort is also reduced. Note that the material supply operation can be performed while moving the kneading pump 51 and the screw pump 57, so that the efficiency is high. As described above, the present invention has been described with reference to the embodiments. However, the present invention can be variously modified in accordance with the gist of the present invention described in the claims, and the present invention does not exclude these.

[0019]

In addition, since the cylindrical material drop opening of a predetermined length formed in the material supply bag completely enters the storage space of the tank and the material falls stably, the generation of dust when the dry mix material falls is minimized. Can be suppressed.
Also, a tank for storing the material is arranged beside the kneading pump and the material is transferred in the lateral direction by the transfer means, so that the height of the material kneading apparatus can be reduced, so that the working space is narrow and the dry space is small. It is suitable for use in special environments where the mix material cannot be stored in large quantities, for example in tunnels. In addition, since the shutter is closed, a large amount of material is stored in the sealed tank.
Even in a wet environment, for example, in a wet tunnel site, a large amount of material can be stored while being kept in a dry state. Also, with the lid of the tank opened, the material input jig is fitted into the material receiving port so as to be located in the material storage space of the tank, and when closing the tank lid, the jig is evacuated from the material receiving port.
