  The present invention relates to a stirring mechanism for stirring powder and a powder filling apparatus including the stirring mechanism.

2. Description of the Related Art Conventionally, a powder filling apparatus that drops powder from a hopper and fills a container is known (see, for example, Patent Document 1).
Patent Document 1 discloses a filling device that drops powder cosmetics (powder) from a hopper and fills a tray (container). The hopper includes a filling cylinder (storage tank) that stores the powder cosmetic inside, and a stirring mechanism that stirs the powder cosmetic stored in the filling cylinder. This stirring mechanism is provided with a fork-shaped stirring needle (stirring bar) inserted into the filling cylinder and stirring the powder cosmetic by its own rotation.

JP-A-6-40851

  However, since the stirring needle described in Patent Document 1 is formed in a fork shape, the locus when the stirring needle is rotated is cylindrical, and there is a problem that the powder cannot be stirred efficiently. . In addition, if the powder cannot be efficiently stirred, it takes time to stir the powder, which causes a problem that the filling efficiency of the filling device is lowered.

  An object of the present invention is to provide an agitation mechanism that can efficiently agitate powder and improve filling efficiency, and a powder filling apparatus including the agitation mechanism.

  An agitation mechanism of the present invention is an agitation mechanism for agitating powder stored in a storage tank. The agitation element is inserted into the storage tank and agitates the powder by its own rotation. A rotating means for rotating, and a stirrer is attached to the tip of the rotating shaft of the rotating means, and a plurality of needle-shaped needles provided on the base and extending in a needle shape toward the side opposite to the rotating shaft side And a beam portion laid between at least a pair of needle-like portions.

  According to such a configuration, the agitation mechanism includes the beam portion laid between at least the pair of needle-like portions, so that the locus when the agitator is rotated is a bottomed cylindrical shape, and the powder Can be efficiently stirred. Moreover, since the stirring mechanism can stir the powder efficiently, the time taken to stir the powder can be shortened.

  In this invention, it is preferable that a beam part connects the front-end | tip of a pair of acicular part mutually.

  According to such a configuration, a pair of needle-like portions and a beam portion can be formed by bending one member at two locations, so that the manufacturing cost of the stirring mechanism can be reduced.

  In the present invention, the base portion has a linear arm perpendicular to the rotation axis, the needle-like portions are provided in a straight line along the arm, and the pair of needle-like portions are provided from the base end to the tip end. It is preferable that the lengths are the same as each other, the distances from the rotation center of the stirrer are the same, and the length from the base end to the front end of the needle-like portion becomes longer as the distance from the rotation center of the stirrer increases. .

According to such a configuration, the needle-like portions are provided in a straight line along the arm, and the pair of needle-like portions have the same length from the proximal end to the distal end, and the base of the needle-like portion is the same. Since the length from the end to the tip becomes longer as the distance from the rotation center of the stirrer increases, the trajectory when the stirrer is rotated becomes a shape in which a plurality of bottomed cylindrical shapes are stacked, and the powder is more efficient. Stir well.
Also, since the pair of needle-like parts have the same distance from the rotation center of the stirrer, the trajectory when the stirrer is rotated has a shape in which a plurality of bottomed cylindrical shapes are concentrically stacked, The powder can be stirred uniformly.

  In the present invention, the base is preferably formed in a cross shape having the two arms.

  According to such a configuration, the stirring mechanism can stir the powder with the two arms having different phases. Therefore, the stirring mechanism can stir the powder more efficiently than the case of stirring the powder with one arm.

  The powder filling apparatus of the present invention is a powder filling apparatus that drops powder from a hopper and fills the container, and the hopper includes a storage tank that stores the powder therein, and a powder stored in the storage tank. The above-described stirring mechanism for stirring the body is provided.

  According to such a configuration, since the powder filling apparatus includes the above-described stirring mechanism, the powder can be efficiently stirred. In addition, since the powder filling apparatus can efficiently stir the powder, the time required for stirring the powder can be shortened, and the filling efficiency can be improved.
