[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid injecting container, and more particularly to a liquid injecting container used for dispensing and dispensing a fixed amount of liquid.

[0002]

[Prior art]

 Conventionally, for example, when casting a molten metal in a melting furnace into a mold in a casting operation, a liquid injection container, that is, a ladle as shown in FIG. 8 has been used.

That is, in this conventional ladle 18, a rod-shaped handle 20 is projectingly provided on the circumferential surface of a bottomed cylindrical hot water pump 19, and in actual use, an operator pumped the molten metal from the melting furnace. After that, the injection port 19a of the hot water pump 19 is brought to a position near the gate of the mold, and a substantially fixed amount of molten metal is poured into the mold while gradually rotating the handle 20.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, since the shape of the hot water bath 19 is cylindrical, the rotation angle of the handle 20 and the pouring amount injected from the hot water bath 19 do not always match, and the hot water bath 19 remains in the hot water bath 19. There is an inconvenience that the pouring position is not fixed depending on the amount of molten metal and so on.Therefore, in the past, the pouring work was carried out by adjusting the pouring amount and pouring position delicately based on the experience of the operator. Of.

However, there is a problem that such a series of casting operations is very complicated and requires a high degree of skill.

Further, ladle 18 having various capacities is prepared depending on the capacity of the mold to be poured at one time and the number thereof, but when the capacity is large, the pouring work is manually performed. Doing this imposes a heavy burden on the worker, and a reduction in work efficiency is unavoidable.

On the other hand, although it is possible to introduce a robot or the like to automate the pouring work, it is very difficult to accurately control the pouring amount as described above. In reality, it is a barrier to automation due to factors such as the above, and has not yet been put to practical use.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and it is possible to inject a fixed amount of liquid into another container or the like in proportion to the rotation angle of the liquid injecting container. By doing so, the task is to contribute greatly to the convenience of automating the injection work.

[0009]

[Means for Solving the Problems]

 That is, in order to solve the above problems, the present invention has a front plate 2 provided with an inlet 2a, and a pair of side plates 3a, 3b vertically extending from both ends of the front plate 2 toward the rear side. The liquid injection container is composed of a back plate 4 facing the front plate 2 and having an arc shape centered on the bottom of the injection port 2a.

[0010]

[Action]

 Therefore, in the case of quantitatively injecting the liquid in the liquid injecting container characterized by the above configuration into, for example, a plurality of other containers, the liquid injecting container is rotated around the bottom of the injection port 2a. However, since the back plate 4 is formed in an arc shape with the bottom of the injection port 2a as the center, the liquid is injected into the container according to the rotation angle of the liquid injection container.

Therefore, if this rotation angle is set constant, a fixed amount of liquid can be accurately injected into each container.

【Example】

 An embodiment of the liquid injection container according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 designates a flat plate-shaped front plate 2, substantially fan-shaped side plates 3a and 3b which are vertically installed so as to face both ends of the front plate 2, and a container bottom portion as shown in FIG. 1 shows a container body constituted by a rear plate 4 formed in an arc shape around a point A of a bottom portion of an injection port 2a formed by notching in a substantially central portion of the front plate 2 to be formed.

Reference numeral 5 denotes a rectangular projecting piece 6 projecting from the upper end of the one side plate 3a, and a projecting piece 6 facing the upper edge of the front plate 2 and the rear plate 4 located on the projecting piece 6 side. The hot water collecting tray comprises a trapezoidal projecting piece 7 and a top plate 8 attached to the tips of the projecting pieces 6 and 7.

Reference numeral 9 denotes a front substantially U-shaped injection nozzle attached along the lower end edge of the injection port 2a of the front plate 2, and 10 denotes a rod-shaped handle vertically provided at the center of the upper end of the other side plate 3b. Indicates.

Although the present embodiment has the above-mentioned configuration, when performing a casting operation into a mold using the liquid injection container 1, a robot 11 as shown in FIGS. 3 and 4, for example, is used. Using.

That is, as shown in FIG. 3, the robot 11 is arranged laterally to the melting furnace 12 and a plurality of molds 13 arranged side by side in an arc shape, and the robot body 14 is vertically rotatable and horizontal. In addition to being pivotable in the direction, a chuck 16 to which the handle 10 of the liquid injecting container 1 can be attached is attached to the tip of an arm 15 thereof so as to be vertically rotatable.

In order to perform a casting operation using this, first, a liquid injecting container 1 having an appropriate capacity is selected in consideration of the capacity of the mold 13 and the number thereof, and the handle 10 is set to the robot 11. Attach it to chuck 16.

Next, as shown in FIG. 3, the robot main body 14 is swung to the melting furnace 12 side, and then is rotated downward to move the liquid injection container 1 from the saucer 6 side to the melting furnace 12 side as shown in FIG. Immerse in the molten metal 17 of. Then, while the molten metal 17 is being pumped, the robot body 14 is first rotated upward as shown in FIG. 2B, and then the chuck 16 is rotated to maintain the liquid injection container 1 in a horizontal state and to maintain the molten metal. Level 17

In this case, since the liquid injection container 1 is provided with the tray 6, even if the molten metal 17 is pumped up with the liquid injection container 1 tilted as shown in FIG. A certain amount of the molten metal 17 can be accurately pumped up so that the liquid level of 17 coincides with the bottom of the injection port 2a of the liquid injection container 1 as shown in FIG. The amount of molten metal pumped in this way is slightly larger than the total volume of the plurality of molds 13 and the total amount of molten metal to be compensated for the volumetric shrinkage of the molten metal 17 in the molds 13.

Thereafter, as shown in FIG. 3, the robot body 14 is swung to the mold 13 side, and the injection nozzle 9 of the liquid injection container 1 comes to a position diagonally above the sprue 13a as shown in FIG. 6 (a). The robot body 14 is rotated in this manner.

Next, the liquid injecting container 1 is rotated to the mold 13 side to inject the molten metal 17 from the sprue 13a. As described above, a certain amount of the molten metal 17 is stored in the liquid injecting container 1. Since the back plate 4 is pumped up and formed in an arc shape centered on the point A at the bottom of the injection port 2a, a fixed amount of molten metal is proportional to the rotation angle of the liquid injection container 1. 17 can be poured.

Therefore, if the rotation angles of the robot body 14 are input in advance by calculating the respective rotation angles from the amount of molten metal to be poured into the mold 13 and the amount of molten metal to be replenished, a certain amount of molten metal 17a After the molten metal is poured, a certain amount of the molten metal 17b to be supplied is poured into the mold 13.

Moreover, since the liquid injection container 1 is rotated around the bottom of the injection port 2a, the pouring position of the molten metal 17 can be fixed and the liquid can be accurately injected into the molten metal port 13a of the mold 13. There is.

Then, in this state, the robot main body 14 is horizontally swung by a desired angle, and similarly, the liquid injecting container 1 is swung by a predetermined angle, and the molds 13 are sequentially transferred to the respective molds 13 as shown in FIGS. The molten metal 17 is poured.

In this way, since a certain amount of molten metal 17 can be poured into each mold 13 depending on the rotation angle of the liquid injection container 1, the robot 11 can perform a series of casting operations. became.

Further, the liquid injection container 1 according to the present embodiment has an advantage that it can be manufactured easily and inexpensively because its structure is extremely simple.

In the above embodiment, the casting operation was performed by using the robot 11, but the robot 11 is not always used depending on the capacity of the liquid injection container 1, the mode of use, and the intended use. There is no need, and it is possible to perform casting work using a simple jig.

Further, in order to satisfactorily pour the molten metal 17 into the sprue 13a of the mold 13, it is preferable to provide the pouring nozzle 9 at the pouring port 2a of the liquid pouring container 1 as in the above embodiment, but such pouring is not always necessary. The nozzle 9 for use may not be provided.

In the case where the injection nozzle 9 is provided, the specific shape and the like are not limited, and the injection nozzle 9 may be provided so that its tip end faces upward as shown in FIG. 7, for example.

Further, the liquid injecting container 1 according to the present invention is not limited to the casting work into the mold 13, and can be widely applied in the case of injecting a liquid into another container in a fixed amount. The intended use does not matter.

Further, the present invention is not limited to the case of dispensing and dispensing a fixed amount of liquid into a container or the like, but is also suitable for injecting a different amount of liquid into each container or the like by appropriately changing the rotation angle of the liquid injecting container 1. Is also applicable.

Further, in the above embodiment, the liquid collecting tray 5 is provided in the liquid injecting container 1 in order to pump up a certain amount of liquid. However, depending on the method of supplying the liquid to the liquid injecting container 1, the liquid collecting tray is It is not necessary to provide 5.

Further, when the amount of liquid supplied to the liquid injection container 1 is small, the time at which the liquid surface of the liquid comes to the injection port 2a can be detected by rotating the liquid injection container 1. Therefore, in this case also, the liquid can be injected quantitatively.
