Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary container mixing apparatus in which two or more kinds of raw materials such as powder are stored in a container, and the container is mixed to rotate the container.
[0002]
[Prior art and its problems]
As the rotary container mixing device, for example, those described in Japanese Utility Model Publication No. 58-17626 and Japanese Patent Publication No. 4-691 are known, but generally have the following problems. In other words, when the charging rate, that is, the ratio of the filling amount in the container to the volume in the container is small, mixing can be sufficiently performed even if the mixing time is short. However, when the charging rate increases, the contents in the shaft center part stay and mix. Was insufficient, and it took a long time to mix thoroughly.
[0003]
An object of this invention is to provide the rotary container mixing apparatus which can perform sufficient mixing in a short time, without producing retention in the accommodation of a shaft center part.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that a container having a container main body and a lid, which is gripped by a rotating device having a horizontal rotating shaft , is rotated to rotate the contents in the container. In the rotary container mixing apparatus, a pair of partition plates facing each other with the axis of the rotation shaft in between are provided in the container, and the pair of partition plates are parallel to the axis of the rotation shaft and are on the ground. extending in a direction perpendicular to, and further connected to each partition plates, on both side edges of the axial direction container inner wall, so that the vertical direction of both side edges on the ground has a gap between the container inner wall, it is provided The pair of partition plates are fixedly supported by a supported body held by the container main body and the lid, and are detachable from the container together with the supported body.
[0005]
According to a second aspect of the present invention, in the configuration of the first aspect, each partition plate is divided and formed, and a plate portion constituting a divided part of the partition plate protrudes from the inner wall of the container body. Has been.

DETAILED DESCRIPTION OF THE INVENTION
1 is a perspective view showing a rotary container mixing device according to an embodiment of the present invention, FIG. 2 is a plan sectional view of FIG. 1, FIG. 3 is a sectional view taken along line III-III in FIG. 1, and FIG. It is IV sectional drawing. This mixing apparatus is configured such that a container 1 is held by a rotating shaft (rotating apparatus) 2 on both side walls. The container 1 includes a container body including a cylindrical portion 11 and a conical portion 12, a lid 13, and a valve 14, and an upper opening of the cylindrical portion 11 is closed with a lid 13. The lid 13 is fixed to the cylindrical portion 11 by fastening the flange 131 to the flange 111 of the cylindrical portion 11. The lid 13 has a center inlet 13a closed with an inlet lid 13b. The conical portion 12 is pointed downward, and the lower opening (discharge port) is closed by a valve 14. The rotating shaft 2 is rotated by a driving source (not shown).
[0007]
Two partition plates 3 are provided in the container 1. The partition plate 3 extends parallel to the axis of the rotary shaft 2 and faces the axis with the axis therebetween. As shown in FIGS. 2 and 3, both side edges 31 in the axial direction of the partition plate 3 are connected to the inner wall of the container body, and both side edges 32a and 32b of the partition plate 3 in the direction perpendicular to the axis are As shown in FIG. 4, the gaps W <b> 1 and W <b> 2 are provided between the inner wall of the container 1. The side edge 32 a has a gap W <b> 1 between the side edge 32 a and the inner wall of the lid 13.
[0008]
The partition plate 3 is provided detachably with respect to the container 1. That is, as shown in FIG. 5, the partition plate 3 is configured separately from the container 1 as an integral part of the ring body 33. The partition plate 3 is fixed while being suspended from the ring body 33. The partition plate 3 is provided in the container 1 with the ring body 33 held between the flange 131 of the lid 13 and the flange 111 of the cylindrical body 11. Both side edges 31 of the partition plate 3 are in contact with the inner wall of the container body.
[0009]
The container 1 having the above-described configuration is filled with several kinds of contents in the previous step, and the container 1 is transported on, for example, a cart with a caster and set on a rotating device. When the rotating device is operated, the contents 4 in the container 1 are mixed as shown in FIGS. FIG. 6 shows the state of the container when the container 1 is in the vertical state. When the container 1 rotates in the direction of the arrow from the state of FIG. 6, the contents in the container 1 become the state of FIG. 6 through the states of FIGS. 7, 8, and 9. In this process, as shown in FIG. 7, a space 51 is formed below the side edge 32 a of the partition plate 3, and as shown in FIG. 9, below the side edge 32 b of the partition plate 3. A space 52 is formed. Since such space portions 51 and 52 are formed, the contents in the sections 40a, 40b, and 40c partitioned by the partition plate 3 flow greatly, and no stagnation occurs in the shaft center portion. Therefore, sufficient mixing is performed in a relatively short time. Further, since the contents can be filled until just before the spaces 51 and 52 are not formed, the charging rate can be increased.
[0010]
Further, since the partition plate 3 can be removed from the container 1 together with the ring body 33, there is no obstacle in the container 1 when the container 1 is cleaned, and therefore cleaning is facilitated.
[0011]
FIG. 10 is a longitudinal sectional view showing a rotary container mixing device according to another embodiment of the present invention. In this embodiment, each partition plate 3 is divided into a main body 3a and two plate portions 3b. As shown in FIG. 11, the plate portion 3b is formed so as to protrude from the inner wall of the container body. As shown in FIG. 12, the main body 3 a is fixed to the ring body 33 via a rod 33 c having a length W <b> 1 and is configured separately from the container 1. The width of the main body 3a is set slightly smaller than the width of the insertion port 13a. The main body 3a is fixed by holding the ring body 33 between the flange 131a of the input port 13a and the periphery of the input lid 13b. The main body 3 a is installed in the container 1 by being inserted into the container 1 to which the lid 13 is fixed from the insertion port 13 a. In FIG. 10, both side edges 31a of the main body 3a are in contact with the side edges 31b of the plate portion 3b. Also in this container 1, since there are gaps W1 and W2 (FIG. 10), a plurality of space portions are generated in the mixing process. Therefore, sufficient mixing can be performed in a relatively short time, and the charging rate can be increased.
[0012]
In addition, in the main body 3a of the partition plate configured separately from the container 1, as shown in FIG. 13, a support rod 30 may be provided between the two main bodies 3a. According to this, the two main bodies 3a become more stable. Of course, also in the case shown in FIG. 5, the support rod 30 may be provided similarly. The main body 3a may be integrated with the lid 13.
[0013]
Further, the shape of the container main body may be round or square. Moreover, the shape of the ring body 33 should just be matched with the shape of a container main body, and the thing of other shapes may be used as long as it is what is not cyclic | annular shape, ie, the thing which can be clamped with the flange 131 and the flange 111.
[0014]
Further, the rotating shaft (rotating device) 2 may be a cantilever type, that is, a single cantilever, as long as it can grip the body of the container 1 and has sufficient strength.
[0015]
【The invention's effect】
As described above, according to the first and second aspects of the present invention, the space portions 51 and 52 can be formed in the mixing process, so that the contents contained in the sections 40a, 40b, and 40c partitioned by the partition plate 3 are increased. It can be made to flow, and the retention of the accommodation thing in an axial center part can be prevented. Therefore, sufficient mixing can be performed in a relatively short time, and the charging rate can be increased.
[0016]
Moreover, since the partition plate 3 can be removed from the inside of the container 1, the inside of the container 1 can be wash | cleaned easily.
