A fixing screw is screwed into the blade holding portion 28, and the blade shaft 30a of the lifting blade 30 can be fixed by the fixing screw.

  On the other hand, on the left side of the vertical rotation shaft 9 on the base 1, a vertical rotation shaft 5 for the container rotation portion 2 is vertically supported by a bearing portion 5a. The lower end of the vertical rotation shaft 5 protrudes into the base 1, and the middle gear 7 is fixed thereto, and the middle gear 7 meshes with the large gear 8 at the lower end portion of the vertical rotation shaft 9. A cup-shaped container holding portion 6 is horizontally fixed to the upper end of the vertical rotation shaft 5, and a kneading container 31 can be inserted and held in the container holding portion 6. The container 31 is a glass or synthetic resin container that contains, for example, an ointment as an object to be kneaded, and can contain a specific ointment and can also be used for kneading. The container 31 is usually covered with a normal lid for storing the ointment, but when kneading is performed, a lid 32 dedicated to kneading is covered. The lid 32 is provided with a hole through which the blade shaft 30a of the elevating blade 30 passes.

  As shown in FIG. 6, the elevating blade 30 inserted into the container 31 is formed by fixing the blade 30b to the lower end of the blade shaft 30a. The blade 30b is formed in a thin plate shape having a substantially triangular shape. A triangular opening 30c is formed inside the blade 30b. As shown in FIG. 6, the blade 30b is located in the same plane as the plane passing through the axis of the blade shaft 30a, and has a flat shape with respect to the blade shaft 30a.

  Thus, since the blade 30b is provided with a thin plate-like blade 30b at the lower end of the blade shaft 30a on the same plane as the blade shaft 30a, the blade 30b is formed in a plane and is very easy to handle during cleaning after use. It is configured to be easy. The elevating blade 30 only moves up and down. For this reason, the blade shaft 30b of the elevating blade 30 is provided with a notch 30d having a shape that is partially narrowed on the shaft. The lift blade 30 has its blade shaft 30a inserted through the hole of the lid 32, and its notch 30d is inserted into the slit 28a of the blade holding portion 28 of the blade support arm 26, and the blade 30b of the lift blade 30 is placed in the container 31. Insert into and use.

  Next, the operation of the kneading apparatus having the above configuration will be described. This kneading apparatus is used for kneading an ointment in a pharmacy such as a hospital. A material to be kneaded (ointment) to be kneaded is placed in a container 31, and this container 31 is also used as a container for storing and storing the material to be kneaded.

  The container 31 containing the material to be kneaded is inserted and placed from above into the container holding part 6 with the storage lid removed. Then, the kneading lid 32 of the container 31 is inserted into the blade shaft 30a of the elevating blade 30, and in this state, the notch 30d of the blade shaft 30a is inserted into the slit 28a of the blade holding portion 28, and the blade support arm 26, the blade 30b is inserted into the container 31, and the lid 32 is fitted to the upper part of the container 31. This completes the setting as shown in FIG. 1, and thereafter, the handle 12 is turned to perform the kneading operation.

  When the handle 12 is turned, the handle shaft 11 rotates, and the vertical rotation shaft 9 rotates via the bevel gear 14. The large gear 8 fixed to the lower end of the vertical rotating shaft 9 rotates, the vertical rotating shaft 5 rotates through the middle gear 7 meshing with the large gear 8, and the container holding portion 6 at the upper end rotates. As a result, the container 31 held by the container holding part 6 rotates about the blade shaft 30a inserted at the center axis position.

  At the same time, the rotation of the vertical rotation shaft 9 causes the horizontal rotation shaft 17 to rotate through the bevel gears 15 and 16, the small gear 18 to rotate, and the large gear 20 that meshes with the rotation rotates. At this time, the cam plate 21 biased and fixed to the large gear 20 rotates, and the cam follower 25 moves up and down while sliding on the outer peripheral surface of the cam plate 21, as shown in FIG. The sliding portion 23 supported by the shaft moves up and down along the lifting guide shaft 22. For example, in FIG. 5, when the large gear 20 rotates clockwise, the cam follower 25 slidably contacting the cam plate 21 first descends, then reaches the descending end, then starts to rise, and after reaching the ascending end, Descend again.

  Thus, while the container 31 held by the container holding part 6 rotates about the blade shaft 30a inserted at the center axis position, the sliding part 23 and the blade support arm 26 extended to the sliding part 23 are provided. The lift blade 30 that moves up and down and is supported by the blade holding portion 28 at the tip of the blade support arm 26 moves up and down in the axial direction of the blade shaft 30a. For example, the container holding portion 6 rotates eight times during one reciprocation from the lower end to the upper end of the blade support arm 26.

  As a result, the container 31 in the container holding unit 6 rotates about the blade shaft 30a, and the lifting blade 30 moves up and down, so that the blade 30b in the container 31 is relative to the material to be kneaded in the container 31. And the rotational position of the blade 30b moves up and down, and the material to be kneaded in the container 31 is kneaded well.

  When the kneading operation is finished, the container 31 is removed from the container holding part 6 with the lifting blade 30 inserted, and the lifting blade 30 is removed from the blade holding part 28 of the blade support arm 26. Then, the lid 32 of the container 31 is removed from the container 31 together with the elevating blade 30 inserted into the small hole in the center, and the blade 30 b is taken out from the material to be kneaded in the container 31.

  At this time, since the flat blade 30b of the lifting blade is formed in a plane passing through the axis of the blade shaft 30a, that is, formed flat with respect to the shaft, the material to be kneaded is like an ointment. Even a highly viscous substance can be easily extracted from the material to be kneaded in the container 31. Further, even when a material to be kneaded is slightly adhered to the extracted blade 30b, the lifting blade 30 is removed while the amount of the adhered material on the blade 30b is reduced by easily scraping it off at the mouth edge of the container 31. Can do.

  Therefore, since there is little adhering matter on the blade 30b, the cleaning operation of the elevating blade 30 after the kneading operation becomes easy. For the container 31 containing the material to be kneaded, the lid is replaced with a lid without a small hole, and the material to be kneaded as it is. Since the container 31 can be used as a storage container, the operation of cleaning the container 31 is not required, and when a plurality of types of materials to be kneaded are individually kneaded in a relatively small amount, the handling thereof is greatly simplified. Can do.

  In the above embodiment, the rotation drive unit 3 is provided with the handle shaft 11 and the handle 12 is manually rotated to rotate the rotation drive unit 3. However, a small motor with a reduction gear is installed instead of the handle to reduce the speed. The shaft of the rotation drive unit 3 can also be rotationally driven by a motor with a machine. Moreover, the peripheral part of the raising / lowering drive part 4 can be covered with a cover body. Furthermore, in the above, the ointment is kneaded as the material to be kneaded, but other chemicals can also be kneaded.
