Next, an example of use and operation of the resin molding machine A equipped with the mixing device 2 having the above construction will be described. However, for convenience of explanation, as shown in FIG. 3, when the already mixed resin molding material C is already accommodated up to the level H1 where the injection nozzle 45 is provided in the main body 20 of the mixing device (about this).

In the state shown in FIG. 3, the level sensor 5 has not detected the upper surface level of the resin molding material C, and the level 1 of the resin molding material C is detected by the level sensor 5 until the level H2.

Next, these resin molding materials C (C1 to C1
When C3) is charged to the level of H2 in the mixing device main body 20, the injection of the resin molding material C is stopped, and then the blower 40 is driven to supply a predetermined compressed air from the injection nozzle 45 to the mixing device main body. It suffices to inject and supply it into 20. As a result, as shown in FIGS. 1 and 2, the resin molding material C newly introduced to a position above the injection nozzle 45 is blown up to form a swirling flow as shown by an arrow a, It blows up and falls repeatedly, and it violently flows. In this way, when all the materials C1 to C3 are blown up, stirred, and made to flow, it is possible to prevent a material having a large specific gravity from sneaking into the lower side of the other material, and to be located above each of the injection nozzles 45. Since the compressed air can be made to act on all areas of the mixing device body 20 located at, the resin molding material C does not remain deposited on a part of the mixing device body 20. Moreover, since the compressed air is ionized, the resin molding materials C1 to C1
Even if static electricity is generated by the mixing of C3, the static electricity ions are attracted to the compressed air and neutralized, so that the static electricity can be prevented in the resin molding materials C1 to C3 and the mixing device main body 20. Therefore, due to the action of static electricity, the resin molding material C
It is possible to uniformly mix different kinds of resin molding materials C1 to C3 in a short period of time without strongly adhering to each other. Further, the compressed air for stirring and mixing is dehumidified and dried air, and since it is heated, it is possible to efficiently perform the drying treatment of the resin molding material C as well, so that the undesired water content is absorbed in the resin molding material C. It is also possible to prevent moisture absorption.

On the other hand, when the screw 30 of the injection molding machine 3 is driven and rotated during the stirring and mixing work of the resin molding material C as described above, the injection nozzle 45 in the main body 20 of the mixing device is more likely to rotate. The resin molding material C after completion of the mixing process, which is stored below, can be taken into the injection molding machine 3 by a predetermined amount. In addition, in the mixing device 2, the mixing device main body 2
Whenever the amount of the resin molding material C in 0 decreases, a new resin molding material C is charged up to the level of the detection level H2 of the level sensor 5, the resin molding material C is mixed, and mixed into the injection molding machine 3. The resin molding material C thus produced can be continuously supplied. That is, while continuously performing the mixing operation of the resin molding material C in the mixing device 2, the injection molding machine 3
Then, the resin molding work using the mold 9 can be simultaneously performed in parallel with this, and the efficient resin molding work can be continuously performed. Moreover, since the resin molding material C used for resin molding is uniformly mixed by the above-mentioned mixing device 2 and sufficiently dried, a resin molded product of good quality can be obtained.

Further, in the resin molding operation as described above, it may be desired to change the color of the molded product. In this color changing operation, it is necessary to discharge all the resin molding material C in the mixing device body 20 and the injection molding machine 3, but the compressed air injected from the injection nozzle 45 cleans the mixing device body 20. Also exerts. In particular, in the present embodiment, since the compressed air has a characteristic of drying the inside of the mixing device body 20 and also preventing static electricity, the inner wall portion or the like in the mixing device body 20 is not affected by the presence of water or static electricity. The molding material C does not adhere. Therefore, when changing colors, it is possible to eliminate the need for performing a complicated cleaning operation inside the mixing device main body 20, and only the inside of the injection molding machine 3 needs to be cleaned. On the other hand, if the resin molding material C is prevented from adhering to the inside of the mixing device main body 20, it is eliminated that the level sensor 5 unduly detects the resin molding material C adhering to the inner surface of the mixing device main body 20. It is also possible to appropriately control the amount of the resin molding material C input into the main body 20.

As can be understood from the above description, according to the powdery or granular material mixing apparatus of the present invention as set forth in claims 1 to 5, a compressed gas is injected into the powdery or granular material to force it. Since it is made to flow and stir, unlike the conventional mechanical stirring with a stirring blade, the granular material with a large specific gravity tends to sink downward, or the granular material in a position where the stirring blade cannot reach Mixing does not become impossible, and even different types of powder and granules having different specific gravities, shapes / sizes, and other physical properties can be mixed efficiently and uniformly. That is a special effect. Moreover, since the compressed gas injected and supplied into the mixing device main body also exerts the action of cleaning each part in the mixing device main body, it is also necessary to perform the cleaning work inside the mixing device main body for each work such as color change. Even when the level sensor is attached, it is possible to avoid the occurrence of an error in the level detection of the powder or granules due to the presence of the powder or granules attached to the main body of the mixing apparatus. Further, unlike the conventional case, it is not necessary to rotatably support and attach the motor-driven stirring blade in the main body of the mixing device, so that the configuration of the entire mixing device can be simplified and convenient for installation, Further, there is a real benefit that the manufacturing cost of the device can be reduced.
