Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a powder filling method and an apparatus therefor, and more particularly to a filling means that can color-code and fill multicolored powder cosmetics into saucers. [Prior Art] Conventionally, this type of powder filling means was disclosed in Japanese Patent Application Laid-Open No. 59-4
The one described in Japanese Patent No. 4205 is known. This involves setting a container without partitions in a mold or frame with partitions, supplying different types of powder cosmetics into the containers for each partition, and then pressing the powder cosmetics without the presence of partitions inside the container. This is a filling method in which multiple types of powdered cosmetics are divided and filled into one container. Specifically, as shown in FIG. 12, a container 14 is installed below a mold 41 that is open at its upper and lower ends and has a partition 21, and a filling space divided by the partition 21 is filled. After supplying powdered cosmetics of different colors, the press head 43, which has a slit 42 for receiving the partition 21, is fitted into the mold 41 to pressurize the powdered cosmetics into the container 14. It is described that the partition 21 is made removable from the mold 41 so that the partition 21 can be removed during pressing, and as a means for filling powder cosmetics into the filling space. As shown in Figure 13,
Control plate 4 with ventilation inside cylindrical container 44 (cylinder)
5 (piston) that is movable up and down, and a suction pipe 46 for sucking air through a control plate 45 is provided in the upper part of the cylindrical container 44.
There is also described one in which the powder cosmetic is placed above the container 3 and sucks the powdered cosmetic into the cylindrical container 44 by suctioning air. How to solve r day by day 1. However, the 12th
When filling the powder cosmetic into the container 14 using the device having the structure shown in the figure, the powder cosmetic is poured into each filling space in the mold 41 partitioned by the partition 21. It is assumed that the filling process is simply dropping the powdered cosmetic from above the mold 41, and if that is the case, the filling speed of the powdered cosmetic into the mold 41 will be slow, and as a result, the powdered cosmetic will fall into the container 14. There is a problem that the filling of powder cosmetics becomes slow. Furthermore, since powdered cosmetics are filled with the upper end opening of the mold 41 open, there is a risk that powdered cosmetics of other colors may get mixed into the adjacent filling space. Furthermore, if the types of powdered cosmetics to be filled in each filling space are different, and in particular, the oil content is different, the filling amount before pressing obtained by back calculation from the volume when pressed into the container 14 will be different for each filling space. Each powder cosmetic is different, so the amount filled in each filling space will be different, but the 13th
In the mold 41 as shown in the figure, the amount of powdered cosmetic to be filled into the filling space must be measured in advance before filling, which is extremely troublesome. Moreover, since the powder cosmetic does not solidify once it is filled into the filling space, the press head 43 is used as a preliminary press.
It is necessary to press the powdered cosmetic with a lever to harden it. In addition, in the device having the structure shown in FIG. 13, as shown in the process diagram shown in FIG. Therefore, the powder sucked into the cylindrical container 44 does not solidify by itself, and when the suction is stopped, it breaks into pieces and falls, creating the trouble of having to perform preliminary pressing. The present invention has been made in view of these points, and its technical object is to provide a powder filling device that increases the filling speed, facilitates the filling operation, and requires little effort in preliminary pressing. [Means for Solving the Problems] In order to solve the above-mentioned technical problems, the present invention takes the following extraordinary technical means. That is, as a first powder filling method, as shown in FIG. Transport the powder onto the vehicle. Then, the compressed air escapes from the air vent passage 4, and only the powder remains in the cylinder 1, which accumulates and solidifies. By sliding the piston 2, this solidified powder is pushed out and filled into the container 14 outside the cylinder 1. do. The powder filling device used in this first powder filling method is
As shown in the figure, the configuration is as follows. That is, this device includes a piston 2 slidably provided in a cylinder l with one end open, and a shield 12 for opening and closing the one end opening of the cylinder l. When the opening is closed by the shield 12, a powder filling chamber 13 surrounded by the piston 2, the cylinder 1, and the shield 12 is formed. Further, at least one of the piston 2 and the shield 12 is formed of a porous member, and forms an air vent path 4 from the powder filling chamber 13. Furthermore, a powder filling port 6 communicating with the powder filling chamber 13 is formed in the cylinder l, and a powder filling pipe 7 is connected to this powder filling port 6.
A mixer 9 for mixing powder and compressed air is connected to the mixer 9, and a compressor 10 is connected to the mixer 9 to form a powder filling device. In addition, as shown in FIGS. 3 and 4, the cylinder l
The inside is partitioned by a partition 21 to form a plurality of powder filling chambers 13 having a predetermined cross-sectional shape, the piston 2 is also divided corresponding to each powder filling chamber 13, and the powder filling port 6 is provided in each powder filling chamber 13@. The powder filling pipe 7 and the mixer 9 may be connected to the powder filling port 6, respectively. At that time, the powder filling port 6 formed for each powder filling chamber 13 is connected to each piston 2, the side wall of the cylinder 1 corresponding to each powder filling chamber 13, or the shield 12 corresponding to each powder filling chamber 13. Form. Next, as a second powder filling method, as shown in FIG. 8, in addition to the first powder filling method, a method of creating a negative pressure inside the cylinder 1 can be considered. That is, the inside of the cylinder 1, in which the piston 2 is slidably provided and the air bleed passage 4 is formed, is made negative pressure by the exhaust from the air bleed passage 4), and in this state, the inside of the cylinder 1 is The powder is conveyed on compressed air, the compressed air escapes from inside the cylinder l through the air vent passage 4, and only the powder remains inside the cylinder l after solidifying.
In this method, the solidified powder is pushed out and filled into the container 14 outside the cylinder 1 by sliding the piston 2. The device used for this second powder filling method is the seventh
As shown in the figure, in the apparatus used for the first powder filling method shown in FIG. It has a similar structure. Also, regarding the apparatus used in this second powder filling method, as shown in FIG. 9, similar to FIGS. The piston 2 is also divided corresponding to each powder filling chamber 13, and each powder filling chamber 1
In addition, a vacuum pump 32 is connected to the exhaust port 5 which continues from each powder filling chamber 13 via the air vent passage 4, and a powder filling port 6 is formed in each powder filling port 6. The powder filling pipe 7, the mixer 91, and the compressor (0 may be connected. Here, the porous member for forming the air vent passage 4 is:
Any filter made of porous metal, felt, cloth, foam, or other material may be used as long as it is breathable and allows only compressed air to pass through and allows only powder to remain. In addition, the powder to be filled includes powdered cosmetics, powdered confectionery, etc.
Any type of material is acceptable as long as it is necessary to fill the container. Furthermore, the container 14 to be filled with powder is a tray for a cosmetic compact or the like. The cylinder 1 described above may be called a mold in some cases, but if it is formed in a cylindrical shape and a piston-shaped object can be slidably inserted inside the cylinder, how can it be called a mold? Of course, it is okay to be called by any other name. [Production V1] In the case of the first powder filling method, as shown in FIG. Form. Next, the powder is mixed with the compressed air from the compressor 10 in the mixer 9 and placed thereon, and the powder is filled into the powder filling chamber 13 from the powder filling port 6 through the powder filling pipe 7. Here, since at least one of the piston 2 and the shield 12 is formed of a porous member to form an air bleed passage 4, only the compressed air escapes from the air bleed passage 4 while filling the powder filling chamber. Only powder is accumulated in 13, and this accumulated powder is pressed and solidified by compressed air. When the powder filling chamber 13 is full of powder, the air flow is blocked by the solidified powder and filling is stopped, so the shield 12 is removed and the solidified powder is pushed out with the piston 2 into the container 14 to be filled. , the filling of the container 14 is completed. As shown in FIG. 3, the inside of the cylinder 1 is partitioned by a partition 21 to form a plurality of powder filling chambers 1a each having a predetermined cross-sectional shape.
The piston 2 is also divided corresponding to each powder filling chamber 13, and the powder filling port 6 is formed for each powder filling chamber 13, and a powder filling tube 7 and a mixer 9 are respectively connected to the powder filling port 6. If the connected devices are used to fill powders of different colors into each powder filling chamber 13, when the containers 14 are filled, multicolored powders can be filled without partitions 21, as shown in FIG. . Next, in the case of the second powder filling method, first, the vacuum pump 3
The inside of the powder filling chamber 13 is made to have a negative pressure by exhausting air from the air bleed passage 4 by 2, and at the same time, the compressor 10 is operated to carry powder into the powder filling chamber 13 with compressed air. This increases the powder filling speed and increases the degree of compaction.
The powder solidifies even more. As shown in FIG. 8, the powder filling apparatus shown in FIG. 7 is prepared, and first, the lower end opening of the cylinder I is closed with a shield 12 to form a powder filling chamber 13. Next, compressor 1
Powder filling chamber 1 in powder 1 with mixer 9 into compressed air from 0
3 is made negative pressure, and the powder is sucked and filled into the powder filling chamber 13 from the powder filling port 6 through the powder filling pipe 7. Here, since at least one of the piston 2 and the shield 12 is formed of a porous member to form an air bleed passage 4, only the compressed air escapes from the air bleed passage 4 while filling the powder filling chamber. Only powder is accumulated in 13, and this accumulated powder is pressed and solidified by compressed air. When the powder filling chamber 13 is full of powder, filling is stopped, the shield 12 is removed, and the solidified powder in the container 4 to be filled is pushed out with the piston 2, and the filling of the container 14 is completed. Note that if the inside of the cylinder 1 is partitioned by a partition 21 to form a plurality of powder filling chambers 13 having a predetermined cross-sectional shape, and each powder filling chamber 13 is filled with powder of a different color using compressed air and negative pressure, When filling the container 14, it is possible to fill the container 14 with multicolored powder without the partition 21, as in the case of the first powder filling method. [Example] 1; 1 Lower - Scream with the example of Takara hitting the (support) side. It should be noted that each of the Examples is a case where powdered cosmetics are filled and pressed into a tray of a compact container. <Example 1> In describing an example of this powder filling method, first,
The device will be explained. As shown in FIG. 1, a piston 2 is provided in a cylinder l whose lower end is open so as to be slidable up and down. A first air cylinder device 3 is connected to the upper end of the cylinder l, and the piston 2 is slid up and down within the cylinder l by the first air cylinder device 3. The piston 2 is made of porous metal, thereby forming an air vent passage 4 which passes from the lower part of the cylinder l through the porous metal to the upper part of the cylinder l. Further, an exhaust port 5 connecting the upper end opening of the cylinder I to the outside air is formed at the connection part between the cylinder I and the first air cylinder device 3, and exhausts the air from the air vent passage 4 to the outside. There is. Furthermore, a powder filling port 6 is formed in the side wall of the cylinder 1, and a powder filling pipe 7 is connected to this powder filling port 6. An on-off valve 8 is provided in the middle of the powder filling tube 7, and a mixer 9 for mixing compressed air and powder is connected to the tip of the powder filling tube 7. This mixer 9 forms a cylindrical container, stores powder therein, and is connected to a compressor 10. In addition, these cylinders 1 and the first air cylinder device 3
As shown in FIG. 2, the whole can be moved vertically by a second air cylinder device 11. moreover,
Pedestal-shaped shield 12 that opens and closes the lower end opening of the cylinder 1
is installed below the cylinder l, and when the cylinder l is lowered by the second air cylinder device 11, its lower end opening comes into contact with the shielding body 12 and is closed, and the side wall of the cylinder l, the piston 2, and the shielding body 12 are closed. A powder filling chamber 13 is formed surrounded by. Next, a method for filling powder into the saucer 14 using this device will be described. The powder to be filled is a powder cosmetic consisting of the following ingredients. Oil content 2: 0 to 25% by weight Powder: 100 to 75% by weight First, the first air cylinder device 3 and the cylinder 1 are lowered by the second air cylinder device 11, and the lower end opening of the cylinder 1 is closed to the shield 12. to form a powder filling chamber 13 [FIG. 2 (aXb)]. And compressor 1
When the on-off valve 8 is opened with 0 activated, compressed air and powder are mixed in the mixer 9, and are carried into the powder filling chamber 13 from the powder filling port 6 through the powder filling pipe 7. Figure 2 (C)]. The compressed air that has entered the powder filling chamber 13 passes through the air vent passage 4 of the porous metal piston 2 and escapes from the exhaust port 5, leaving only the powder in the powder filling chamber 13. In the powder filling chamber 13, the powder is pressed by compressed air and solidified. Then, the inside of the powder filling chamber 13 becomes full of powder within an instant, so the opening/closing valve 8 is closed to stop the introduction of powder [FIG. 2(d)]. Next, the cylinder 1 is raised together with the first air cylinder device 3 by the second air cylinder device 11, and the shield 1 is raised.
2 and open the lower end opening [Figure 2 (e)
]. At this time, the powder in the cylinder 1 is solidified and is in a pre-pressed state, so that it is held without falling from the lower end opening of the cylinder 1. Then, the cylinder 1 is positioned on the saucer 14 to be filled, and then the first air cylinder device 3 is operated to push out the solidified powder with the piston 2 and fill it into the saucer 14 [Figure 2 (fX
g)]. Then, if necessary, this solidified powder is actually pressed using a press device (not shown) to complete the filling press into the tray 14. Note that in this first embodiment, the shield 12 may also be formed of porous metal like the piston 2. In this way, the air bleed passage 4 has two routes: one that passes through the piston 2 and exits to the exhaust port 5, and the other that passes through the shield 12 and exits to the outside, and the escape of compressed air becomes even better. Filling of the powder into the cylinder 1 becomes smoother. <Example 2> This example is basically the same as Example 1 except that the inside of the cylinder 1 is divided into a plurality of powder filling chambers 13 by partitions 21. That is, as shown in FIGS. 3 to 5, the cylinder 1 is formed into a rectangular cylindrical shape, and the inside thereof is partitioned by a partition 21 whose cross-sectional shape depicts Mt. A filling chamber 13 is used. The piston 2 is also divided corresponding to each powder filling chamber 13, and a powder filling port 6 is formed in the side wall of the cylinder 1 for each powder filling chamber 13, and a powder filling tube 7, A mixer 9 is connected. Then, the cylinder 1 with the shield made of porous metal] 2
The lower end opening of the chamber was closed, and the powder cosmetic was conveyed into each powder filling chamber (3) using compressed air, as in the case of Example 1. The components of the powder cosmetic to be filled are as follows. Mt. Fuji part: Oil content: 25% by weight Powder: 75% by weight Color: Vermilion sky part: Oil content: IO weight% Masquerade: 90% by weight Color: Blue cloud part, Oil content: -15% by weight Powder...85% by weight Color...gray Sea part: Oil...5% by weight Powder...95% by weight Color...light blue Here, powder cosmetics are based on the oil content. Because the ratio of the volume after pressing to the volume before pressing (compression ratio) differs due to the difference in the particle size of the powder and the difference in the particle size of the powder, the amount of powder cosmetic to be filled into each powder filling chamber 13 is determined in advance for each powder cosmetic. In this respect, in this embodiment, the piston 2 is divided corresponding to each powder filling chamber 13, so the volume of each powder filling chamber 13 can be changed depending on the pulling condition of the piston 2. The volume before pressing can be adjusted by changing the volume of each powder filling chamber 13 so that when the powder cosmetics in each powder filling chamber 13 are pressed to the same thickness. In addition, by setting the pulling force of each piston 2 to the same height and changing the pressure of compressed air, each powder filling chamber 1
The filling and clouding amount of the powder cosmetics to be filled into the container 3 is adjusted, and the same effect as before is achieved according to the compression ratio of each powder cosmetic. Furthermore, when filling multiple colors of the same powder cosmetic with different colors, the compression ratio is the same, so the lifting height of each piston is the same. Then, the compressed air used for filling the powder escapes from the shield 12 to the outside, and only powdered cosmetics are filled into the powder filling chamber 13.Then, the shield 12 is removed and each powder filling chamber 13 is filled with powder cosmetics.
The solidified powder is simultaneously pushed out with each piston 2 corresponding to the
As shown in FIG. 5, the solidified powder is actually pressed into the tray 14 to complete the filling. Therefore, it is possible to fill multicolored powders in a desired shape. <Embodiment 3> As shown in FIG. 6, in addition to that of Embodiment 2, the cylinder 1 and the shield 12 are housed in the box 22, and the powder filling port 6 is is not provided on the side wall of the cylinder l, but is formed by a tube 23 that passes through the box body 22 and the shielding body 12, forming a space between the shielding body 12 and the bottom of the box body, and communicating with the outside from this space. Connect the exhaust port 5 to the box body 2
2, the compressed air passes through the shield 12 and is exhausted to the outside from the exhaust port 5 through the space. The other points are the same as in the second embodiment. <Embodiment 4> In addition to the steps of the first powder filling method shown in FIG. 2, the first air cylinder device 3 Lower the piston 2 with the compressed air, further press the solidified powder with the piston 2, and do 4rals.

This is a method of filling JIILm+14. According to this, the press becomes more reliable. <Example 5> In describing an example of the second powder filling method, first, the apparatus will be described. As shown in FIG. 7, a vacuum pump 32 is added to the apparatus used in the first powder filling method shown in FIG.
An exhaust pipe 31 is connected to the exhaust port 5, a vacuum pump 32 is connected to the tip of the exhaust pipe 31, and an on-off valve 8a is installed in the middle of the exhaust pipe 31.
is provided. Since the other points are the same as those in Example 1, the same reference numerals are given and the explanation thereof will be omitted. However, the code of the on-off valve on the compressor 10 side is 8b. Next, a method for filling powder into the saucer 14 using this device will be described. The powder to be filled has the same components as in Example 1. As shown in FIG. 8, first, the first air cylinder device 3 and the cylinder 1 are lowered by the second air cylinder device 11, and the lower end opening of the cylinder 1 is closed with the loose body 12, and the powder filling chamber 13 is closed. [Figure 8 (a) (b)
]. Then, when the on-off valves 8a and 8b are opened with the vacuum pump 32 and compressor IO operating, the powder filling chamber 13 becomes negative pressure, and the compressed air and powder are mixed in the mixer 9, and the powder is mixed with the powder. is carried into the powder filling chamber 13 from the powder filling port 6 through the powder filling tube 7 by the suction force of negative pressure and the compression force of compressed air [FIG. 8(C)]. The compressed air that has entered the powder filling chamber 13 passes through the air vent passage 4 of the porous metal piston 2 and escapes from the exhaust port 5, leaving only the powder in the powder filling chamber 13. In the powder filling chamber 13, the powder is compressed and solidified by the negative pressure from the vacuum pump 32 and the pressing force from compressed air. Then, the inside of the powder filling chamber 13 becomes full of powder within an instant, so the opening/closing valves 8a and 8b are closed to stop the introduction of powder [Fig.
d)】. Next, the cylinder 1 is raised together with the first air cylinder device 3 by the second air cylinder device 11, and the shield 1 is raised.
2 and open the lower end opening [Figure 8 (e)
]. At this time, the powder in the cylinder 1 is solidified and is in a pre-pressed state, so that it is held without falling from the lower end opening of the cylinder 1. Then, the cylinder 1 is positioned on the tray 14 to be filled, and then the first air cylinder device 3 is operated to push out the solidified powder with the piston 2, filling the tray 14 [Fig. 8(f) ( g
)]. Then, if necessary, this solidified powder is actually pressed using a press device (not shown) to complete the filling press into the tray 14. In this way, the powder is filled into the powder filling chamber 13 with the pressure of compressed air and the pressure of the negative pressure of the vacuum pump 32, so the filling speed is fast and the accumulated pressing force inside the powder filling chamber 13 is also reduced. Larger and more solidified. In this fifth embodiment, the shield 12 may also be made of porous metal like the piston 2. By doing this, the air vent passage 4 has two routes: one that passes through the piston 2 and exits to the exhaust port 5, and the other that passes through the shield 12 and exits to the outside.
As a result, the compressed air can escape even better, and the powder can be filled into the cylinder l more smoothly. Further, in this embodiment, even if only the vacuum pump 32 is operated without operating the compressor 10, the powder can be filled and solidified into the cylinder l by operating in the same manner. The operation and effect in this case are substantially the same as in the case of filling only with compressed air in the first embodiment. <Embodiment 6> This embodiment is basically the same as Embodiment 5 except that the inside of the cylinder 1 is divided into a plurality of powder filling chambers 13 by partitions 21 as in FIG. 3 showing Embodiment 2. That is, as shown in FIG. 9, a powder filling port 6 is formed in the side wall of the cylinder 1 for each powder filling chamber 13, and a powder filling pipe 7 and a mixer 9 are connected to the powder filling port 6, respectively. cylinder 1
An exhaust port 5 is formed in the upper part of the exhaust pipe 31 and a vacuum pump 3.
2 are connected, and each powder filling chamber 13 is connected to a vacuum pump 3.
2, the powder is loaded onto compressed air by the compressor 10 and carried into each powder filling chamber 13. Since the other points are the same as in the second embodiment, the same reference numerals are given and the explanation thereof will be omitted. <Embodiment 7> As shown in FIG. 10, the shielding body 12 is formed of porous metal, the cylinder l and the shielding body 12 are housed in a box body 22, and the powder filling port 6 is is not provided on the side wall of the cylinder I, but is formed by a tube 23 that passes through the box body 22 and the shielding body 12, and furthermore, a space is formed between the shielding body 12 and the bottom of the box body, and from this space the outside is An exhaust port 5 is formed in the box body 22, and a vacuum pump 32 is connected to the exhaust port 5 through an exhaust pipe 31. Compressed air passes through the shield 12 and passes through the space from the exhaust port 5 to the vacuum pump. 32, the air is sucked in and exhausted to the outside. The other points are the same as in Example 6. <Example 8> This is a device that is basically the same as Example 5, in which the powder is directly filled into the saucer 14 and the main press is carried out.As shown in FIG. are formed concentrically, and the saucer 14 is fitted into this recess.
Place the cylinder l on top and cover the receiver m114 itself with the shield 12.
The lower end opening of cylinder I is closed as a powder filling chamber [
3 is formed, the powder is filled into the powder filling chamber 13 using E1m air and negative pressure from the vacuum pump 32, and the powder is actually pressed into the receiver 14 by the piston 2. A saucer 14 is filled with powdered cosmetics. <Embodiment 9> In addition to the steps of the powder filling method shown in FIG. 8, the first air cylinder device 3 lowers the piston 2, and the powder that has been solidified by compressed air and negative pressure is further pressed by the piston 2 and solidified, and then extruded from the cylinder 1 and filled into the saucer 14. According to this, the press becomes more reliable. [Effects of the Invention] According to the present invention, since the powder is filled into the cylinder together with compressed air, the powder can be filled into the cylinder extremely quickly, and as a result, the work of filling the powder into the container can be simplified. can be done quickly. In addition, the powder filled and accumulated in the cylinder solidifies under the pressure of compressed air, making it easier to fill the container into the container. Filling the powder into the cylinder using negative pressure already acts as a preliminary press, so in this respect as well, the time required to fill the powder into the container can be shortened, and the operation is extremely easy. Color separation by filling multicolor powders using a powder is a particularly useful method for forming patterns. Patterns can be easily formed using colored powder cosmetics. Furthermore, there is no risk of the powder spilling out of the cylinder when the powder is filled into the cylinder, and compared to filling the container into the container using the conventional square cutting method, no powder is wasted, making it extremely economical. When the inside of the ring is made to have a negative pressure with a vacuum pump, the filling speed increases due to the force of the negative pressure, and the powder solidifies even more, making each of the above-mentioned effects even greater.
