 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 to 3 show an embodiment of the present invention, in which 1 is a machine body, 2 is a support portion supported by the body body 1 so as to be vertically movable, and 3 is a support portion 2. It is a guide body that guides up and down. Reference numeral 4 denotes an elevating mechanism for moving the supporting portion 2 up and down, which is constituted by an air cylinder 5 in this embodiment. 6 is a rod.

Reference numeral 7 denotes a main rotating shaft rotatably supported by the supporting portion 2, and the main rotating shaft 7 is on the same axis as the central axis of a container 9 for containing an object to be stirred placed on a base 8. It is supported by the supporting portion 2 so as to be located at. Reference numeral 10 is a main motor that rotates the main rotation shaft 7, and is provided on the support portion 2. Gears 11 and 12 transmit the rotation of the main motor 10 to the main rotation shaft 7.

Reference numeral 13 denotes an attachment body fixed to the lower portion of the main rotary shaft 7, and a fulcrum shaft 14 is provided on the attachment body 13 at a predetermined horizontal distance L from the axis of the main rotation shaft 7. Reference numeral 15 is a stirring motor in which a stirring rotating shaft 16 is attached in the vertical direction. The stirring motor 15 is supported by the fulcrum shaft 14 so as to be rotatable in the vertical direction. Reference numeral 17 denotes a stirring blade provided at the tip of the stirring rotating shaft 16.

Reference numeral 18 denotes a rotating mechanism for rotating the agitating motor 15. The rotating mechanism 18 includes an air cylinder 19 in this embodiment, and one end fixed to the agitating motor 15 and the other end being an air cylinder. It is composed of a lever 21 rotatably attached to the tip of a rod 20 of 19 and the stirring motor 15 is rotated about the fulcrum shaft 14 via the lever 21 as the rod 20 expands and contracts. .

Next, the operation of the above embodiment will be described. The support portion 2 moves up and down by operating the air cylinder 5 that constitutes the lifting mechanism 4. When the main motor 10 provided in the support portion 2 is driven, the main rotation shaft 7 rotates via the gears 11 and 12, and the stirring motor 15 supported by the fulcrum shaft 14 with a horizontal distance L on the main rotation shaft 7. Also, the stirring rotary shaft 16 attached to the stirring motor 15 revolves around the distance L as a radius. When the agitating motor 15 is driven, the agitating rotary shaft 16 rotates, and the agitating blade 17 provided at the tip of the agitating rotary shaft 16 rotates (rotates).

Then, the agitating motor 15 and the agitating rotary shaft 16 move in a vertical direction about the fulcrum shaft 14 via a lever 21 by operating an air cylinder 19 which constitutes a rotating mechanism 18. do.

Stirring of an object to be stirred such as a high-viscosity liquid contained in the container 9 is performed as follows. First, the elevating mechanism 4 is actuated to raise the support part 2, and then the container 9 containing the object to be stirred is supported on the base 8 by the support part 2 at the central axis thereof. Place it so that it coincides with the axis of the main rotating shaft 7 (Fig. 1).

Next, the rotating mechanism 18 is operated to rotate the stirring motor 15 to rotate the stirring rotation shaft 16 attached to the stirring motor 15, and the stirring blade 17 is moved to the central shaft of the container 9. Position it near. In this state, the elevating mechanism 4 is operated to lower the support part 2, the stirring rotary shaft 16 is put in the container 9, and the stirring blade 17 is positioned near the bottom surface of the container 9 (FIG. 2).

Next, the stirring motor 15 for rotating the stirring rotating shaft 16 and the main rotating shaft 7 are rotated. As a result, the stirring blade 17 revolves around the center bottom surface of the container 9 while rotating, and stirring of the same portion is performed. Then, in this state, the elevating mechanism 4 is operated to move the support portion 2 up and down, whereby the stirring blades 17 continuously move up and down, and the center portion of the container 9 is stirred. In addition, in this state, the rotating mechanism 18 is operated to rotate the rotating shaft 16 for stirring, and the stirring blade 17 is pressed against the side surface of the container 9 (FIG. 3).

As a result, the container 9 is thoroughly stirred in the entire circumferential direction and in the vertical direction near the side surface of the container 9. These agitating operations are continuously repeated from the central portion to the side surface portion of the container 9 by appropriately operating the elevating mechanism 4 and the rotating mechanism 18, if necessary. Even if the size of the container 9 is changed, the stirring blade 17 is surely brought into contact with the entire circumference of the side surface of the container 9 by the operation of the rotating mechanism 18 even if the size of the container 9 changes.
