  However, when the container to be filled has a small diameter, it is difficult to appropriately perform automatic filling with an auger. This is because if the diameter of the container is smaller than the discharge port of the auger, the powder discharged from the discharge port will spill out of the container, making it difficult to fill the container with a fixed amount. Therefore, conventionally, filling with a small diameter has been performed manually by measuring a specified amount of powder and using a jig. On the other hand, in order to automate such work, a countermeasure to introduce a small-auger dedicated auger can be considered, but simply reducing the diameter of the discharge port will clog the powder near the discharge port. Problems arise.

  Therefore, an object of the present invention is to enable automation of powder filling even for a small-diameter container.

In order to solve such a problem, the first invention provides a powder filling device for filling powdery cosmetic powder in a container having a small-diameter opening . This powder filling apparatus is provided with an auger that discharges powder contained in a hopper from a discharge port and an input port that faces the discharge port at the top, and is spaced apart from the opening of the container. The guide nozzle has an inverted conical shape in which a discharge port that is smaller than the opening of the container and has a smaller diameter than the input port is provided at the bottom, and a vibrator that vibrates the guide nozzle in the vertical direction. Outlet, Ru is arranged so as to be separated in the vertical direction with respect to the opening of the container even if the state odor guide nozzle is displaced vertically downward by the vibration of the vibrator.

Here, in the first invention, the vibrator preferably vibrates the guide nozzle in at least one of a vertical direction and a horizontal direction. Further, inlet guide nozzles, it large heard is preferred over the discharge port of the auger. Further, the discharge port of the guide nozzle may have an end shape whose lower end changes in a non-linear manner.

2nd invention provides the powder filling method of filling the powder of powder cosmetics in the container which has an opening part of a small diameter . In this powder filling method, a charging port is provided at the top, and is opposed to the opening of the container so as to be separated from the opening of the container. The discharging port having a smaller diameter than the charging port is smaller than the bottom of the container. The first step of vibrating the inverted conical guide nozzle provided in the vertical direction, the second step of charging powder into the charging port, and the powder charged from the charging port into the inner surface of the guide nozzle And a fourth step of dropping the powder guided to the discharge port from the discharge port and filling the container with the powder. Outlet, Ru is arranged so as to be separated in the vertical direction with respect to the opening of the container even if the state odor guide nozzle is displaced vertically downward by the vibration of the vibrator.

Here, in the second invention, the second step above SL may be a step to introduce separately a predetermined amount of powder to be filled into the container a plurality of times.

  According to the present invention, the guide nozzle is interposed between the discharge port of the auger and the opening of the container, and the powder discharged from the discharge port is guided to the container side by the guide nozzle. Since the guide nozzle is vibrated by the vibrator, the fluidity of the powder in the guide nozzle is ensured. Therefore, even when the discharge port is made small in correspondence with a small-diameter container, powder is not clogged in the guide nozzle and does not spill out of the container from the discharge port. It is possible to effectively fill the specified amount of powder. As a result, it is possible to appropriately automate the powder filling of a small-diameter container with only a simple improvement over existing equipment.

  FIG. 1 is an overall configuration diagram of a powder filling apparatus. This powder filling apparatus 1 is mainly composed of a hopper 2, an auger 3, a guide nozzle 4, and a vibration mechanism 5, and automatically powders such as powder cosmetics and powder chemicals are automatically put in a container 6. Quantitatively fill. The container 6 has a bottomed cylindrical bottle shape, and an opening 6 a provided at the top thereof is smaller than the discharge port 3 b of the auger 3.

  In the hopper 2, powder to be filled in the container 6 is accommodated. The auger 3 rotates the screw 3a by a power source (not shown) such as a motor, and guides the powder stored in the hopper 2 to the lower discharge port 3b. And the powder guide | induced to the discharge outlet 3b is discharged below by the speed according to rotation of the screw 3a. The amount of powder discharged from the discharge port 3b is determined by the amount of rotation of the screw 3a.

  The guide nozzle 4 has a guide function of guiding the powder discharged from the discharge port 3b of the auger 3 to the container 6 side. The guide nozzle 4 has an inverted conical shape that is open at the top and bottom, and is provided with an inlet 4a at the top and an outlet 4b at the bottom. The input port 4a is opposed to the discharge port 3b of the auger 3 with a slight distance therebetween, and its diameter is larger than that of the discharge port 3b to prevent the powder from spilling out of the input port 4a. Yes. Further, the discharge port 4b is slightly separated from the opening 6a of the container 6, and its diameter is smaller than that of the opening 6a in order to prevent the powder from spilling out of the opening 6a. . As shown by the broken line in FIG. 2, the discharge port 4b may have an end shape with a linear lower end. However, in order to effectively prevent clogging of the powder in the guide nozzle 4, a solid line in FIG. As shown, the end may have an end shape that changes non-linearly. Specifically, it is a curved wave shape or a saw-tooth shape. The guide nozzle 4 is supported by the vibration mechanism 5, so that the guide nozzle 4 is stably interposed between the auger 3 and the container 6.

  The vibration mechanism 5 includes a support base 5a, an arm 5b, and a vibrator 5c. Specifically, the support base 5a placed on a horizontal plane extends vertically upward, and a flat arm 5b is attached thereto. The arm 5b having a fixed end as an attachment site of the support base 5a extends in the horizontal direction, and a guide nozzle 4 is attached to an open end corresponding to the tip thereof. And the vibrator 5c which vibrates up and down (vertical direction) with a comparatively high frequency is attached to the upper surface of the arm 5b. The vibration of the vibrator 5c is transmitted to the guide nozzle 4 via the arm 5b, whereby the guide nozzle 4 also vibrates up and down. The vibration direction of the guide nozzle 4 may be a horizontal direction, or may be a two-dimensional direction that combines the vertical direction and the horizontal direction. In particular, if the guide nozzle 4 is vibrated in a two-dimensional direction, the fluidity of the powder in the guide nozzle 4 can be more effectively ensured.

  Hereinafter, the process of filling powder in the small-diameter container 6 using the above-described powder filling apparatus 1 will be described. First, the container 6 is disposed immediately below the guide nozzle 4. Next, in a state where the guide nozzle 4 is oscillating, a specified amount of powder measured by the auger 3 is discharged from the discharge port 3 b, and the powder is charged into the input port 4 a of the guide nozzle 4. This specified amount corresponds to the filling amount to be filled in the container. However, if all of this amount of powder is charged at once, there is a concern about clogging of the powder in the guide nozzle 4 or a decrease in the discharge speed. In such a case, the prescribed amount of powder may be divided into a plurality of times (for example, two times) with a time interval.

  The powder charged from the inlet 4a is guided to the outlet at the bottom along the inclined inner surface of the guide nozzle 4. In this process, the vibrator 5c vibrates the guide nozzle 4 by its own vibration. This vibration ensures the fluidity of the powder in the guide nozzle 4. Therefore, even if the discharge port 4b has a small diameter, powder clogging is unlikely to occur. The powder guided to the discharge port 4b falls from the discharge port 4b, whereby the container 6 is filled with the powder. The guide nozzle 4 vibrates at a relatively high frequency, but its amplitude itself is not so large. Therefore, even if the guide nozzle 4 is displaced, it will contact the auger 3 or the container 6, or the opposing openings (the discharge port 3b and the input port 4a or the discharge port 4b and the opening 6a) may be displaced. There is no end.

  As described above, according to the present embodiment, the guide nozzle 4 is interposed between the discharge port 3 b of the auger 3 and the opening 6 a of the container 6, and the powder discharged from the discharge port 3 b is transferred to the container by the guide nozzle 4. Lead to the 6th side. In the powder filling process, the guide nozzle 4 is vibrated by the vibrator 5c. Therefore, even when the discharge port 4b is made small corresponding to the small-diameter container 6, the guide nozzle 4 is not clogged with powder, and may be spilled out of the container 6 from the discharge port 4b. Absent. As a result, it becomes possible to fill the container 6 with a predetermined amount. At the same time, the quantitative filling of the small-diameter container 6 can be appropriately automated only by a simple improvement such as adding the guide nozzle 4 and the vibration mechanism 5 to the existing equipment (general-purpose auger 3). As a result, the work time required for the filling process can be shortened and the number of workers can be reduced, so that the work efficiency can be significantly improved.

  In addition, although the patent document 1 mentioned above mentions the hopper with a vibrator as the prior art, the patentability of this invention is not denied by this. In the powder filling machine according to this prior art, a vibrator is provided at a narrow discharge port at the bottom of the hopper into which the powder cosmetic is charged, and the discharge port is vibrated for a certain time. Due to this vibration, a substantially predetermined amount falls from the outlet, and the powder cosmetic is filled in the container. As can be seen from this operation, the function of the vibrator according to the prior art is only the measurement of the powder cosmetic, and is not intended to prevent clogging of the powder as in the present invention.
