(Problems to be Solved by the Invention) The filling of articles by the above-mentioned method is performed by randomly supplying the flaky articles (the postures thereof are indefinite), and each of them is housed in a container and the postures thereof are dispersed inside. In addition, since the edges of the flaky article are entangled with each other to form a large amount of space in the container, only a small amount can be filled in with respect to the specified storage capacity of the container, and filling cannot be performed with good yield. Further, as shown in the bottom of the container in the figure, since most of the flaky articles are accommodated in a laterally overlapping manner, it is difficult to pinch the flaky articles when taking them out of the container, and the lateral articles are taken out when taking them out. Generates many damaged products that are crushed or broken. Etc. have various problems. The present invention has been made to solve the above-mentioned problems, and an article formed in the shape of a thin piece is vertically aligned in a container by a vibrating body inserted into the container, resulting in good yield. The purpose is to provide a method of filling. (Means for Solving the Problem) Means of the present invention for achieving the above-mentioned object are as follows: a thin container in the shape of a cylindrical container having an open upper part and an inner peripheral wall formed in a circular shape, and the outer peripheral part thereof. The rod-shaped vibrating body is inserted so as to have the accommodation space of the container, and the flaky article is supplied from the container opening, and along the inner peripheral wall of the container while giving a slight vibration to the flaky article housed in the cylindrical container. In the method of filling the flaky articles, the sheets are mutually moved and aligned vertically. In addition, a hollow cylindrical vibrating body having a space for accommodating the flaky article is inserted into an outer peripheral portion of the cylindrical container having an open upper portion and a circular inner peripheral wall, and the container opening is formed. And a thin piece which supplies the thin piece-shaped article from the opening of the hollow vibrating body and mutually moves along the inner peripheral wall of the container while giving a slight vibration to the thin-piece-shaped article housed in the cylindrical container, thereby vertically aligning the thin piece. There is a method for filling the shaped article. Furthermore, the lower end of the hollow vibrating body is closed, a discharge hole is formed in the lower peripheral side, and the thin piece-like article supplied from this opening is filled into the container by the discharge hole. Filling method. (Operation) The present invention has the following effects due to the above configuration. When the vibrating body is operated while the vibrating body is inserted into the cylindrical container while gradually supplying a predetermined amount of the flaky article from the upper opening of the container, the flaky article is predetermined by the vibrating body. Given a slight vibration of amplitude and frequency,
The container is horizontally moved little by little, and its posture is aligned substantially parallel to the container wall, that is, the sheets are aligned vertically. Then, when the above-described operation is continuously performed up to the opening portion along with the filling, the flaky article is filled in the container in the vertical direction without any gap and with good yield. Also, in the case where the vibrating body is formed hollow and the flaky article is supplied in parallel with this opening and the opening of the container,
The same action as described above is exhibited. Further, when the discharge hole of the flaky article is provided on the lower peripheral side of the vibrating body, the product supplied from the upper opening and reaching the discharge hole is supplied toward the peripheral wall of the container and is the same as described above.

It is preferable that the vibrating body 3 is concentrically inserted into the center of the container 1 so as to uniformly apply an exciting force to the article A.
This may be provided eccentrically, or may be rotated at a predetermined speed. The cross-sectional shape is circular as shown in FIG.
As shown in Fig. 10, a polygonal shape (including a triangle, a square, and a polygon)
Alternatively, it is formed into a flat shape as shown in FIG. 11 or a needle-like thin wire (not shown), and its cross-sectional area is arbitrarily selected according to the volume of the container 1, the size and the property of the article A, etc. To do. Further, the vibrating body 3 is not necessarily limited to molding by a hard material, and may be formed by a flexible or elastic material, for example, a sponge system. Further, as shown in FIG. 12, a through hole 4 is provided inside the vibrating body 3.
And a discharge hole 5 is provided at the lower end, and the article A is fed from the upper opening and supplied into the container 1 through the discharge hole 5. FIGS. 13 to 14 show another example of the hollow vibrating body 3 described above, in which the lower end of the hollow vibrating body 3 is closed and a peak-shaped guide portion 6 is provided at the center of the closed body. Then, the discharge hole 5a, which is continuous along the slope of the guide portion 6, is attached to the vibrating body 3
Has been drilled at one or more locations on the peripheral wall. When the article A is focused on the container 1, one or a plurality of the vibrators 3 are appropriately selected and used, and the volume of the container 1 and the size and properties of the article A are used. In addition to the above, the use conditions are changed depending on the amplitude and frequency of the vibrating body 3. When using the above-mentioned thin needle needle, a large number of them are provided in the container 1 at predetermined intervals. After the article A is filled into the container 1 to some extent, the rectangular thin wire is inserted into the article A so as to be embedded therein. In FIG. 15, reference numeral 7 denotes a filling hopper, the lower part of which faces the opening of the container 1, and a weighing section 8 is provided at the upper part thereof, and the weighed article A is sent to the hopper 7 for quantitative filling. . Next, the operation of the above-described embodiment will be described.

Example 1 In this example, as shown in FIG. 2, a solid rod-shaped vibrating body 3 is inserted into a cylindrical container 1, and a fixed amount of fish feed A is filled into the container 1. Indicates. The container 1 having an inner diameter of 60 mm and a height of 80 mm is placed on the table 2, and the hopper 7 containing the weighed bait A is placed in the container 1.
To the opening of the container, and from the hopper 7 into the container 1
The solid vibrating portion 3a of the vibrating body 3 having a length of 20 mm and a length of 120 mm was inserted with its tip slightly separated from the inner bottom surface of the container 1. In this state, the vibrating means 3b of the vibrating body 3 was driven to give a slight vibration to the bait A through the vibrating section 3a. Then, the bait A gradually dropped into the container 1 and aligned vertically along the inner peripheral wall of the container 1 due to the mutual movement due to vibration, as shown in FIG. In this phenomenon, as shown by an arrow P in FIG. 3, a force that tries to enter the inside of the vibrating body 3 acts, and each thin piece bait A supplied in a horizontal state is applied to the vibrating body 3. The shaking gradually tilted them into a vertical orientation, and they overlapped each other vertically. The next thin flakes A that started to lean into the gap between the overlapping thin flakes A, which also overlapped vertically. Thus, the above operation was continuously performed between the inner wall of the container 1 and the vibrating body until a saturated state, that is, a high density was reached. Then, as the bait A is filled, the vibration part of the vibrating body 3 is gradually added.
When 3a is pulled up, the prescribed amount of bait A is completely filled while the lower end of the vibrating part 3a reaches the opening of the container 1, and the filled state has no space, and the thin piece bait A vibrates. It was carried out at a high density in the container 1 while maintaining its original shape. The total amount of the filling material was able to be filled in a required time of 10 seconds with respect to the planned filling amount of 100 g. By the way, according to the conventional filling method, only 65 g can be filled, and the required time is 2 minutes. Further, when the article A is taken out from the container 1, the articles A are vertically aligned and entered, so that the article A can be easily pinched with fingers from the opening of the container 1 and smoothly taken out without being damaged. In this example, when the plate-shaped vibrating body 3 was used and the vibrating portion 3a was inserted into the container 1 until the filling was completed, the bait A was vertically aligned as described above, A dense packing was performed.

Example 2 In this example, as shown in FIG. 7, when the hollow vibrating body 3 having the through hole 4 is inserted into the cylindrical container 1 and the fish feed A is filled into the container 1. Indicates. The sizes of the container 1 and the vibrating body 3 are the same as those in the first embodiment described above, and the vibrating portion 3a of the vibrating body 3 is placed in the container 1 in a state where the tip thereof is slightly separated from the inner bottom surface of the container 1. Inserted. Then, when the bait A was supplied from the opening of the container 1 and the opening of the vibrating section 3a respectively, the bait A was gradually filled in the container 1 by the microvibration of the vibrating body 3, and the vibrating section 3a was pulled out and filled at the same time. Upon completion, Bait A was vertically aligned and densely packed as before.

[Third Embodiment] In this embodiment, as shown in FIG. 8, a hollow vibrating body 3 having a through hole 4 and a vibrating portion 3a in which a discharge hole 5a is formed in three directions on a lower peripheral wall is provided. The case where the fish bait A is inserted into the shaped container 1 and the container 1 is filled is shown. The sizes of the container 1 and the vibrating body 3 are the same as those in the first embodiment described above, and the vibrating portion 3a of the vibrating body 3 is placed in the container 1 in a state where the tip thereof is slightly separated from the inner bottom surface of the container 1. Inserted. Then, when the bait A is supplied only from the opening of the vibrating section 3a, the bait A is gradually filled from the discharge hole 5a toward the inner wall of the container 1 by the slight vibration of the vibrating body 3, and the vibrating section 3a is pulled out. At the same time, the filling was completed, and the bait A was vertically aligned and densely packed as described above. In this example, when the vibrating body 3 was rotated at a low speed in a certain direction, the filling time was shortened. (Effects of the Invention) As described above, in the method for filling flaky articles according to the present invention, even if the flaky articles are randomly supplied into the container, the posture thereof is all corrected vertically by the vibrating body inserted into the container. Since it takes a uniform posture, unnecessary voids in the container are reduced as much as possible, so that a large amount of articles can be packed, and articles with good yield can be filled. Since it is filled vertically, the article can be easily pinched when it is taken out and is easy to handle, and the article is not damaged when taken out. It has special effects such as.
