1 to 4, the powder vacuum filling apparatus 1000 includes a hopper 100; nozzle 200; container detection sensor 300; Nozzle lifting unit 400; support 500; Powder transfer unit 600; Compressed air injection unit 700; and a switching valve 800 .

The hopper 100 may store the powder therein. For example, the powder may include at least one of cosmetics, pharmaceuticals, and quasi-drugs, but is not limited thereto. According to the embodiment, at least a portion of the powder stored in the hopper 100 may further include solid, liquid, gel and/or gaseous contents. For example, the hopper 100 may be stored in a state in which at least a portion of the solid powder contains moisture. Even if solid, liquid, gel and/or gaseous contents are included, when the main content is powder, it can be seen that the powder is stored in the hopper 100 . For the convenience of description, in the following specification, it is described that the powder is stored in the hopper 100, but this means that only the powder is stored in the hopper 100, and in addition to the powder in the hopper 100, other solid, liquid, gel and / Or it may include all of the gaseous contents are stored.

In an embodiment, the hopper 100 may include a powder accommodating portion having a shape in which the inner diameter decreases toward the lower side. Powder may be stored in the powder receiving unit. In the conventional powder filling container, when the powder stored in the hopper 100 is discharged, the powder at the outlet side of the hopper 100 is intensively transferred and the powder at the other parts is delayed, so the powder at the outlet side of the hopper 100 is delayed. There was a problem with this hollowing out cave phenomenon. In the present invention, even if a cave phenomenon occurs in the powder stored in the powder accommodating part as the powder is discharged, the powder is distributed by itself as the powder flows along the slope formed according to the decrease in the inner diameter inside the powder accommodating part, so that the cavern phenomenon can be minimized. there is.

In an embodiment, the hopper 100 may include a hopper vibrating unit 110 . The hopper vibrating unit 110 may generate vibration inside the hopper 100 . When vibration occurs by the hopper vibrating unit 110, the powder stored in the powder receiving unit is flattened, and the cavern phenomenon can be minimized. Through this, the powder stored in the powder accommodating unit may be uniformly transferred to the first connector 210 in the entire area.

The nozzle 200 may be connected to the hopper 100 , the powder transfer unit 600 , and/or the compressed air ejection unit 700 . A negative pressure is formed inside the nozzle 200 by the powder transfer unit 600, whereby the powder moves from the hopper 100 toward the nozzle 200, but the powder in the nozzle 200 is discharged to the filling container to Charging may be performed. In addition, during the charging, there may be a problem that the powder is clogged inside the nozzle 200 (and the first connector 210 ) and the hopper 100 , and at this time, the compressed air injection unit 700 is inside the nozzle 200 . The agglomeration of the powder can be removed by spraying compressed air into it. In particular, in the present invention, as the compressed air is injected into the nozzle 200, the powder filling efficiency can be significantly improved because the agglomeration of the powder is effectively removed even in the first connection pipe 210, which has a narrow diameter and the powder is easily agglomerated. there is.

In the embodiment, the compressed air may mean air compressed to have a pressure sufficient to remove the agglomeration of the powder inside the nozzle 200 (and the first connection pipe 210 ) and the hopper 100 . The pressure of the compressed air may be freely adjusted by the type of powder, the size of the nozzle 200 (and the first connecting pipe 210 ) and the hopper 100 . In addition, the air may include at least one of nitrogen gas, oxygen gas, argon gas, helium gas, and a mixed gas having a composition corresponding to the atmosphere, but is not limited thereto, and may include a combination of various gases.

In the embodiment, the nozzle 200 is formed in the form of a tube having a hollow in the longitudinal direction therein so as to at least temporarily receive the powder transferred from the hopper 100 and then discharge it to the outside, and relatively at the upper end of the hopper It is connected to 100 so that the powder is introduced and an outlet is relatively formed at the lower end, so that the powder can be discharged. However, the present invention is not limited thereto.

In the embodiment, the nozzle 200 is connected to the hopper 100 through a first connecting pipe 210 , and connected through a selector valve 800 (and a selector valve 800 ) through a second connecting pipe 220 . It may be connected to the powder conveying unit 600 and the compressed air jetting unit 700).

According to an embodiment, the first connector 210 and/or the second connector 220 may be hard and/or soft, and may include, for example, a material such as rubber, plastic, or metal. However, the present invention is not limited thereto.

In an embodiment, the second connector 220 may be connected to the nozzle 200 from the lower side of the first connector 210 . As will be described later, since a negative pressure is formed in the nozzle 200 through the second connection pipe 220 , when the first connection pipe 210 is located above the second connection pipe 220 , the hopper 100 ), the powder may be transferred toward the nozzle 200 .

In an embodiment, when the filling container is located under the nozzle 200 , the nozzle 200 may move downward and may be in close contact with the filling container. Accordingly, while the outlet of the nozzle 200 communicates with the inlet of the filling container, the nozzle 200 and/or the inside of the filling container may be sealed from the outside. When the inside of the nozzle 200 and/or the filling container is not sealed, the negative pressure formed inside the nozzle 200 is canceled by atmospheric pressure, so the powder does not move from the hopper 100 to the nozzle 200 or moves at a very slow speed. Since air is not supplied from the outside when the inside of the nozzle 200 and/or the filling container is sealed, the powder can smoothly move from the hopper 100 to the nozzle 200 by the negative pressure inside the nozzle 200 state can be

In the embodiment, the nozzle 200 is a nozzle tube 230 having a hollow formed therein in the longitudinal direction; and a nozzle tip 240 coupled to one side of the nozzle tube 230 and having an outlet formed at one end.

In an embodiment, the nozzle tip 240 is configured in plurality, and each nozzle tip 240 may be different from the other nozzle tips 240 . Accordingly, the plurality of nozzle tips 240 may be replaced according to the specifications of the filling container. However, the present invention is not limited thereto.

In an embodiment, the plurality of nozzle tips 240 may include a first nozzle tip and a second nozzle tip. In this case, the first nozzle tip may have a smaller outer diameter than the second nozzle tip. For example, the first nozzle tip may be used by being coupled to the nozzle tube 230 when the filling container is a container with a narrow mouth (eg, a blow type container), and the second nozzle tip is a filling container. When the inlet is a wide container (eg, a jar (Jar) type container), it may be used in combination with the nozzle tube 230 . However, the present invention is not limited thereto.

In an embodiment, a buffer member may be disposed in one area of the lower end of the nozzle tip 240 . Due to the buffer member, when the nozzle 200 moves downward and comes into close contact with the filling container, the impact caused by the contact between the nozzle 200 and the filling container may be alleviated. However, the present invention is not limited thereto.

The container detection sensor 300 may detect that the filling container is located below the nozzle 200 . For example, the container detection sensor 300 may detect when a container is located at a predetermined position (eg, a bottom surface positioned below the nozzle 200). When it is sensed that the filling container is positioned below the nozzle 200 by the container detection sensor 300 , the nozzle 200 may move downward.

At this time, as the spring 434 is compressed between the support part 500 (in particular, the support plate 520 ) and the wing part 433 , it is possible to relieve the repulsive force between the cylinder 410 and the piston 420 . As the repulsive force is alleviated, the nozzle 200 may safely adhere to the filling container without applying an excessive impact to the filling container. In addition, since the elastic force acts downward from the support part 500 (in particular, the support plate 520 ) by the compression of the spring 434 , the downward elastic force by the spring 434 acts on the nozzle 200 to the nozzle Adhesion performance between 200 and the filling container may be enhanced.

For example, when the size of the filling container is large, the filling time (a) may be set to be long, and the descending delay time (b) and the compressed air injection time (d) may be set to be short. In addition, for example, when the discharge rate of the powder is fast, the filling time (a) may be set to be short, the falling delay time (b) and the compressed air injection time may be set to be long. Also, for example, when a large amount of powder needs to be filled in the filling container, the filling time (a) may be set to be long, and the compressed air injection time (d) may be set to be short. However, the present invention is not limited thereto.

Referring to (A) of Figure 5, when the container detection sensor 300 detects that the filling container is located at the lower side of the nozzle 200, the descending delay time (b) is counted, and the descending delay time (b) is After the elapse of time, the nozzle 200 is descended, and the charging time (a) may be started when descending. When the filling time (a) is started, the switching valve 800 may allow the second connection pipe 120 and the powder transfer unit 600 to communicate with each other, thereby forming a negative pressure inside the nozzle 200 . While the nozzle 200 is in close contact with the filling container, the outlet of the nozzle 200 and the inlet of the filling container communicate with each other, and the powder is discharged from the hopper 100 to the filling container by the negative pressure inside the nozzle 200, and the powder is filled This can be done.

Simultaneously with filling, that is, when the filling time (a) is counted, the counting of the first compressed air delay time (c) is started, and when the first compressed air delay time (c) has elapsed, the switching valve 800 turns on the second By allowing the connection pipe 120 and the compressed air injection unit 700 to communicate with each other, the compressed air may be injected into the nozzle 200 .

The agglomeration of the powder in the hopper 100 , the nozzle 200 , and/or the first connection pipe 210 may be removed by the injection of the compressed air.

When the first compressed air injection time (d) has elapsed, the switching valve 800 allows the second connection pipe 120 and the powder transfer unit 600 to communicate again, so that the powder can be continuously filled. Accordingly, it is possible to fill without agglomeration of the powder over the entire filling time (a).

Referring to FIG. 5B , compressed air may be sprayed twice during the filling of the powder. That is, by adjusting the set number of times of the compressed air delay time (c, c') and the compressed air injection time (d, d'), the powder can be filled without agglomeration of the powder during the filling regardless of the filling time (a). .

Specifically, after the first compressed air injection time (d) has elapsed, the switching valve 800 allows the second connection pipe 120 and the powder transfer unit 600 to communicate with each other to form a negative pressure inside the nozzle 200 . By doing so, the filling of the powder is made again, but the second compressed air delay time (c`) can be counted.

When the second compressed air delay time c` elapses, the switching valve 800 allows the second connection pipe 120 and the compressed air injection unit 700 to communicate with each other, and the compressed air is secondarily injected into the nozzle 200 . can make it happen At this time, the injection of the secondary compressed air may be made during the second compressed air injection time (d'). When the second compressed air injection time d` has elapsed, the switching valve 800 allows the second connection pipe 120 and the powder transfer unit 600 to communicate again, so that the powder can be continuously filled. . Accordingly, it is possible to fill without agglomeration of the powder over the entire filling time (a).

The operation 1000 of the vacuum powder filling apparatus shown in FIG. 5 is exemplary, and various configurations may be applied according to an embodiment to which the present invention is applied. For example, the charging time (a) is counted after the falling delay time (b), but depending on the embodiment, the falling delay time (b) and the charging time (a) may be simultaneously counted.
