Description

[Industrial application field]

The present invention relates to a powder filling method and an apparatus therefor, and more particularly to a filling means capable of filling different colors of multicolored powder cosmetics into a saucer. [Prior Art] Conventionally, as a powder filling means of this type, Japanese Patent Laid-Open No. 59-4
The one described in Japanese Patent No. 4205 is known. In this, a container 14 without a partition is set in a mold or a frame having a partition 21, and different types of powder cosmetics are provided in the container 14 for each partition 21.
After the powder is supplied to the container 14, the powder cosmetic is pressed without the partition 21 existing in the container 14, and a plurality of types of powder cosmetics are partitioned and filled in one container 14. Specifically, as shown in FIG. 8, the container 14 is installed below the mold 41 having the upper and lower ends and the partition 21 and the filling space divided by the partition 21 is colored. Slits to accept divider 21 after supplying different powder cosmetics
The press head 43 forming 42 is fitted in the mold 41 to pressurize the powdered cosmetic material to fill the container 14, or the partition 21 can be removed from the mold 41, at the time of pressing. It is described that the partition 21 is removed, and as a means for filling the filling space with the powdered cosmetic material, as shown in FIG. 9, air permeability is provided in a cylindrical container 44 (cylinder). A control plate 45 (piston) having the same is provided so that it can be moved up and down, and a suction pipe 46 for sucking air through the control plate 45 is provided in the upper part of the cylindrical container 44 to provide a device for storing the powder cosmetics in the storage portion 33. It is also described that the powder cosmetic is installed in the upper part and sucks the powdered cosmetic into the cylindrical container 44 by sucking air. [Problems to be Solved by the Invention] However, using the device having the structure shown in FIG.
When filling the powder cosmetics in the container 14,
It is considered that the filling of the powder cosmetics into the respective filling spaces in the mold 41 partitioned by 21 simply drops the powder cosmetics from above the mold 41, and if so, the mold 41. There is a problem that the filling speed of the powder cosmetic into the container is slow, and as a result, the filling of the powder cosmetic into the container 14 is delayed. Further, since the powder cosmetics are filled with the upper end opening of the mold 41 being open, powder cosmetics of various colors may be mixed in the adjacent filling spaces. Moreover, if the type of powder cosmetics to be filled in each filling space is different, especially if the oil content is different,
The filling amount before pressing, which is obtained by back-calculating from the volume when pressed in 14, is different for each powder cosmetic, and therefore the filling amount for each filling space is different, but as shown in FIG. In the mold 41, the amount of the powdered cosmetic material to be filled in the filling space has to be measured in advance before the filling operation, and the filling operation is extremely troublesome. Moreover, the powder cosmetic does not solidify only by filling it in the filling space, so it is necessary to press and solidify the powder cosmetic with the press head 43 as a preliminary press. Further, in the apparatus having the structure shown in FIG. 9, as shown in the process diagram shown in FIG. 10, the lower end opening of the cylindrical container 44 is installed so as to be in contact with the upper surface of the powder reservoir 33 and suction is performed. Therefore, the powder sucked into the cylindrical container 44 does not solidify by itself, and when the suction is stopped, it falls into pieces and falls, and there is the trouble of having to perform a preliminary press. The present invention has been made in view of the above points, and it is a technical object to provide a powder filling means that increases the filling speed, facilitates the filling work, and requires less time and effort for preliminary pressing. [Means for Solving Problems] The present invention has the following technical means in order to solve the above technical problems. That is, in the powder filling method of the present invention, the piston 2 is slidably provided in the cylinder 1 having the lower end opened, and the lower portion of the piston 2 in the cylinder 1 is used as the filling space 13, and the filling space 13 is used for air suction. Inside of the filling space 13 by connecting the above-mentioned cylinder 1 to the air vent passage 4 and lowering the cylinder 1 into the bottomed powder storage portion 33 in which the powder is accommodated and pressurizing it, while making the inside of the filling space 13 a negative pressure. After the powder is sucked into the container, the cylinder 1 is rotated in a state where the filling space 13 is filled with the powder, the cylinder 1 is taken out from the powder reservoir 33, and the piston 2 is slid to move the container 14 outside the cylinder 1. Then, the solidified powder is extruded and filled. Here, the mass cutting action is more reliable when the cylinder 1 is lowered and press-fitted until the lower end opening of the cylinder 1 comes into contact with the bottom of the powder reservoir 33, and the cylinder 1 is rotated in the contact state. As an apparatus used for this powder filling method, a piston 2 formed of a porous member is slidably provided in a cylinder 1 having an opening at the lower end, and the upper end side of the cylinder 1 is connected to a vacuum pump 32. A vacuum pump 32 sucks air from the lower end of the cylinder through an air vent passage 4 passing through a piston 2, and the inside of the cylinder 1 is partitioned by a partition 21 to form a plurality of filling spaces 13 having a predetermined cross-sectional shape. The piston 2 is divided corresponding to each filling space 13, and the exhaust port 5 is formed corresponding to each filling space 13, and the vacuum pump 32 is formed at each exhaust port 5.
There is a device connected to. Here, the porous member for forming the air vent passage 4 is
A porous metal, a felt, a cloth, a foam material, a filter made of another material, or the like, which has air permeability and allows only compressed air to pass through and allows only powder to remain. The powder to be filled may be any powder as long as it needs to be filled in the container, such as powder cosmetics and powder confectionery. Further, the container 14 to be filled with the powder is a cosmetic compact saucer or the like. The cylinder 1 may be called a mold in some cases, but any cylinder may be used as long as it is slidably inserted with a piston. Of course, it does not matter if they are called with such names. [Operation] As shown in FIG. 2, a powder filling device is prepared, and the cylinder 1 thereof is lowered into the bottomed powder storage portion 33 and press-fitted therein,
The vacuum pump 32 is operated. Then, the filling space 13 becomes a negative pressure through the piston 2 forming the air vent passage 4 by the porous member, and the powder is sucked. That is, the powder is filled in the filling space 13 by the press-fitting into the powder storage portion 33 of the cylinder 1 itself and the suction by the negative pressure. The powder is compressed and filled in the filling space 13 by the pressure due to the press-fitting into the powder storage portion 33 of the cylinder 1 and the pressure due to the negative pressure, and the powder is solidified. When the cylinder 1 is rotated in this state, so-called mass cutting is performed. Therefore, the suction by the vacuum pump 32 is stopped or continued, and the cylinder 1 is taken out from the powder reservoir 33, and the piston is removed. 2 is slid to push out the solidified powder to fill the inside of the container 14. EXAMPLES Examples of the present invention will be described below with reference to the drawings. In each of the examples, the powder cosmetic is filled and pressed in the saucer of the compact container. <Example 1> First, a first example will be described based on the powder filling apparatus shown in FIG. A piston 2 is vertically slidably provided in a cylinder 1 whose lower end is opened. A first air cylinder device 3 is connected to the upper end of the cylinder 1, and the piston 2 is vertically slidable in the cylinder 1 by the first air cylinder device 3. Inside the cylinder 1 and below the piston 2, there is a filling space 13. The piston 2 is formed of a porous metal, so that an air vent passage 4 is formed from the filling space 13 in the lower portion of the cylinder 1 through the porous metal to the upper portion of the cylinder 1. Further, the cylinder 1 connected to the air vent passage 4
An exhaust port 5 connecting the upper end opening of the and the outside air is formed at a connection part between the cylinder 1 and the first air cylinder device 3, and a vacuum pump 32 is connected to the exhaust port 5 via an exhaust pipe 31. . An opening / closing valve 8 is provided in the middle of the exhaust pipe 31. In addition, the cylinder 1 and the first air cylinder device 3
Is a second air cylinder device, as shown in FIG.
11 allows it to move up and down as a whole. Next, a method of filling powder in the pan 14 using this apparatus will be described. The powder to be filled is a powder cosmetic containing the following components. Oil content: 0 to 50% by weight Powder: 100 to 50% by weight Powder cosmetics are stored in advance in the bottomed powder storage portion 33, and are always kept at the same depth by the leveling plate 34. . Then, the apparatus of this embodiment is positioned above the powder reservoir 33, and the vacuum pump 32 is operated. Next, open the on-off valve 8,
The air in the filling space 13 is exhausted through the exhaust pipe 31, the exhaust port 5, and the piston 2 forming the air vent passage 4, and the inside of the filling space 13 becomes a negative pressure, so from the lower end opening of the cylinder 1. Outside air is sucked

[Figure 2 (a)]. In this state, the second air cylinder device 11 lowers the cylinder 1 together with the first air cylinder device 3 until the lower end opening of the cylinder 1 comes into contact with the bottom of the powder reservoir 33.
Then, while the powder is sucked into the filling space 13,
The powder is pushed into the filling space 13 by the lowering of the cylinder 1, and the powder cosmetic in the filling space 13 is pressed and solidified by the pressing force by suction and the drag force from the bottom of the powder reservoir 33.

[Figure 2 (b)]. Therefore, the cylinder 1 is rotated together with the first and second air cylinder devices 3.11. As a result, an action similar to so-called mass cutting is performed at the lower end opening portion of the cylinder 1.

[Fig. 2 (c)]. After that, the second air cylinder device 11 raises the cylinder 1 together with the first air cylinder device 3 from the powder storage portion 33 and takes it out. At that time, the powder cosmetic in the filling space 13 is solidified. Self-held in the cylinder 1 by the
The powder cosmetics in the filling space 13 do not shatter and fall even if the

[Fig. 2 (d) (e)]. Finally, the piston 2 is slid by the first air cylinder device 3 to push out the solidified powder to the pan 14 outside the cylinder 1, and the main press is performed to complete the filling of the pan 14. <Example 2> In this example, the lower portion of the piston 2 in the cylinder 1 is partitioned 21.
It is basically the same as the first embodiment except that it is divided into a plurality of filling spaces 13. That is, as shown in FIG. 3 and FIG. 4, the cylinder 1 is formed in a rectangular tubular shape, and the inside thereof is divided by a partition 21 having a cross-sectional shape depicting Mt. Fuji, the sky, clouds, and the sea to form a plurality of filling spaces. 13 Then, the piston 2 is divided corresponding to each filling space 13,
Each piston 2 is made of a porous metal, and an air vent passage 4 through which air escapes from the lower part of the cylinder 1 to the upper part through the piston 2.
To form. In addition, cylinder 1 for each filling space 13
An exhaust port 5 is formed in the upper part of the container, and an exhaust pipe 31 and a vacuum pump 32 are connected to the exhaust port 5, respectively, so that the air can be discharged from the filling space 13 via the air vent passage 4 by this vacuum pump. . Then, each filling space 13 is filled with the powdered cosmetic material of the next component, and is filled and pressed in the saucer 14. Mt. Fuji: Oil content: 50% by weight Powder: 50% by weight Color: Vermilion Sky: Oil content: 20% by weight Powder: 80% by weight Color: Blue Cloud: Oil content:・ 10 wt% powder ・ ・ 90 wt% color ・ ・ ・ Gray Sea part: oil ・ ・ 30 wt% powder ・ ・ 70 wt% color ・ ・ ・ light blue Depending on the ingredients of the powder cosmetic, press Since the ratio (compression ratio) of the volume after pressing to the volume before pressing is different, it is necessary to change the amount of powder cosmetics to be filled in each filling space 13 in advance for each powder cosmetic. In this respect, in this embodiment, since the piston 2 is divided corresponding to each filling space 13, the volume of each filling space 13 can be changed depending on the pulling condition of the piston 2, and the powder in each filling space 13 can be changed. When the cosmetics are fully pressed, the volume before pressing can be adjusted by changing the volume of each filling space 13 so that they are pressed to the same thickness. When the same powder cosmetics of different colors are used, the compression ratio is the same, so the piston 2 of each powder filling space is used.
Just pull them to the same height. Further, the filling of the powder cosmetics into each filling space 13 is basically the same as that of the first embodiment, but since there are a plurality of powder cosmetic filling spaces 13, the work performed in the first embodiment is repeated a plurality of times. There is a need. That is, as shown in FIG. 5, in this embodiment, it is necessary to fill four types of powder cosmetics, that is, the part of Mt. Fuji, the part of the sky, the part of the cloud, and the part of the sea. Only the piston 2 is pulled up to form a filling space 13, the on-off valve 8 corresponding to this filling space 13 is opened to make the filling space 13 a negative pressure, and in this state, the cylinder 1 is placed in the powder cosmetic material of the powder reservoir 33. After descending and press-fitting and filling powder filling material into the filling space 13 of Mt. Fuji, cylinder 1 is rotated to cut into masses.

[Fig. 5 (a)], Cylinder 1
Raise. Next, pull up the piston 2 in the empty part to fill the filling space.
Forming 13

[FIG. 5 (b)] The cylinder 1 is lowered and pressed into a powder reservoir 33 in which powder cosmetics to form an empty portion are stored, and the powder cosmetic is filled in the filling space 13 in the empty portion. When cylinder is filled, rotate cylinder 1 and raise it

[Fig. 5 (c)]. Further, although not shown in the figure, the piston 2 in the cloud part is pulled up to form the filling space 13, and the cylinder 1 is lowered into the powder storage part 33 in which the powder cosmetic material for forming the cloud part is stored. When the powder cosmetic is filled in the filling space 13 in the cloud part, the cylinder 1 is rotated and raised. Finally, pull up the piston 2 in the sea to form the filling space 13.

[Fig. 5 (d)] The cylinder 1 is lowered into the powder storage portion 33 in which the powder cosmetic material to be filled in the sea portion is stored and press-fitted to fill the space 13 with the powder cosmetic material in the sea portion. After filling, rotate cylinder 1 and raise it

[Figure 5 (e)]. Then, all the pistons 2 corresponding to the filling spaces 13 are lowered to push out the powder cosmetics into the saucer 14 to fill them, and then the main press is performed.

[Fig. 5 (f) (g)] Filling is completed as shown in Fig. 6. In this case, unlike the device of FIG. 1, since the area of the lower surface of the cylinder 1 is large, when the cylinder 1 is lowered into the powder reservoir 33, the lower end opening of the cylinder 1 reaches the bottom of the powder reservoir 33. Although the resistance is a little too high, even if the lower end opening of the cylinder 1 does not reach the bottom of the powder reservoir 33, the pressing space at the time of descending causes a filling space.
It can be said that the force applied to the powder cosmetics in 13 is substantially the same as when the lower end opening of the cylinder 1 is in contact with the bottom of the powder reservoir 33. Therefore, the powder cosmetics in the filling space 13 is As in the case of the first embodiment, the solidification is achieved by the negative pressure of the vacuum pump 32 and the drag force received from the powder reservoir 33 side. In addition, after filling the powder cosmetics in the Mt.Fuji area, the powder cosmetics of other colors are filled in the cloud, sky, and sea areas, so the bottom of the solidified powder cosmetics previously filled should now be filled. The powdery cosmetic material will be slightly attached. However, this portion is located at the inner bottom portion of the tray when it is filled in the tray 14, so there is no particular problem. As described above, by forming the partition 21 into an arbitrary shape, it is possible to fill the multicolored powder with a desired shape. <Example 3> This is a method of performing multicolor powder filling using the powder filling apparatus of Example 1. As shown in FIG. 7, two powder filling devices are prepared. One of them is a cylinder 1 formed according to the size of the saucer 14.
The other has a cylinder 1B having a cross-sectional area smaller than that of the cylinder 1A and having a predetermined cross-section. First, with the powder filling device equipped with the cylinder 1A, the saucer 14 is filled with the powder cosmetics by the filling method shown in FIG.

[Fig. 7
(a)]. When the filling is completed, the cylinder 1B of the other powder filling device is lowered to the solidified powder cosmetic already filled in the pan 14 and a part thereof is cut off.

[Fig. 7 (b) (c)]. Exhaust the solidified powder cosmetics cut with the cylinder 1B.

[7th
As shown in FIG. 2 (d), again, in the same manner as the powder filling step of FIG. 2, the powder cosmetic of a different color from the powder cosmetic filled in the pan 14 is filled in the cylinder 1B.

[Figs. 7 (e) and (f)]: Cylinder 1B is aligned with the previously cut portion and lowered, and piston 2 pushes and fills solidified powder cosmetic material of another color to raise cylinder 1B.

[Fig. 7 (g)]
(h)】. By doing so, it is possible to easily fill the multicolor powder without partitioning the inside of the cylinder 1. <Example 4> In order to perform multicolor powder filling using the apparatus of Example 1, the following method is also available. For example, four devices shown in FIG. 1 are prepared, and the cross-sectional shape of each cylinder is made into the shapes of Mt. Fuji, sky, cloud, and sea shown in FIG. 6 so that they can be combined like a puzzle.
Then, each powder filling device is arranged on the turntable or on the conveyor in the transfer direction at equal intervals, and the saucer 14 is conveyed by these turntables or conveyors, and the saucer 14 is stopped under each powder filling device. Powdered cosmetics of each shape are sequentially filled in the saucer 14, and finally finally pressed by a pressing device. <Example 5> In addition to the steps of the powder filling method shown in FIG. 2, the piston 2 is lowered by the first air cylinder device 3 after suction of the powder by the negative pressure, and the negative pressure and the powder reservoir 33 are removed. This is a method in which the powder that has been solidified by the reaction force is further pressed by the piston 2 to be solidified, and then is extruded from the inside of the cylinder 1 to fill the pan 14. In this way, the powdered cosmetic material hardens and solidifies. [Advantages of the Invention] According to the present invention, the powder is sucked into the filling space by the negative pressure, and at the same time, the cylinder is press-fitted into the powder storage portion. Therefore, the filling of the powder into the filling space can be performed very quickly. As a result, the powder filling operation into the container can be performed quickly. Further, since the powder filled and accumulated in the filling space is solidified by the negative pressure or the drag force from the powder storage portion side, the filling into the container becomes easy, and in some cases, the main press is not required,
Even when this press is required, the filling of the powder into the filling space by compressed air or negative pressure already acts as a preliminary press, and in this respect as well, it is possible to shorten the filling time of the powder into the container. The work is extremely easy. Furthermore, there is no risk of the powder spilling out of the cylinder when the powder is filled into the filling space, and there is no wasted powder compared to the conventional filling into the container by the mass cutting method, which is extremely economical.
