First, in FIG. 1, the paint agitator includes a fixed base 6 and a plurality of, for example, a pair of rotating members 7 ₁ and 7 ₂ supported on the base 6 so as to be rotatable about a horizontal axis, and these. The movable base 8 connected to the rotating members 7 ₁ and 7 ₂ of the movable base 8, the tray 9 pivotally supported by the movable base 8, and the movable base 8 that can contact the surface of the tray 9 facing the movable base 8. A plurality of, for example, a pair of coiled springs 10 ₁ and 10 ₂ arranged above and one of the pair of rotating members 7 ₁ and 7 ₂ 7 ₁ connected to the rotary drive arranged on the base 6. A coating container 12 to be agitated is provided on the tray 9 with a hand 11.

With reference to FIG. 2, FIG. 3 and FIG. 4 together, the base 6 includes a base main portion 6a formed in a rectangular parallelepiped shape and a lower side of one side of the base main portion 6a. It is formed in a substantially L-shaped cross section with the flange portion 6b protruding toward one side, and is fixed on a floor surface (not shown).

On the base main part 6 a of the base 6, a rotation driving means 11 is arranged at one end side in the longitudinal direction thereof. The rotation driving means 11 is composed of a prime mover 13 having a horizontal rotation axis and a speed reducer 14 coaxially connected to the prime mover 13. Thus, the output shaft 15 of the speed reducer 14 is extended above the flange 6b of the base 6 with a horizontal axis. On the other hand, a bearing portion 17 is provided on the other end side in the longitudinal direction on the base main portion 6a, and a rotary shaft 16 having an axis parallel to the output shaft 15 is rotatable on the bearing portion 17. Is pivotally supported.

The rotating members 7 ₁ and 7 ₂ are each formed in a disk shape, and the central portion of one rotating member 7 ₁ is fixed to the output shaft 15 and the rotating member 7 _{2 has} a center portion. The part is fixed to the rotating shaft 16.

The movable table 8 has a horizontal plate portion 8a, which is disposed above the two rotary members 7 _1, 7 _2, so as to face from one side of the horizontal plate portion 8a in the two rotary members 7 _1, 7 ₂ back And a connecting plate portion 8b that hangs downwards are formed into a substantially L-shaped cross section, and the connecting plate portion 8b is a rotating member via a connecting shaft 18 ₁ parallel to the output shaft 15. In addition to being connected to 7 ₁ , it is also connected to the rotating member 7 ₂ via a connecting shaft 18 ₂ parallel to the rotating shaft 16. Therefore, both rotary members 7 ₁ and 7 ₂ are connected to each other via the movable base 8. When one rotary member 7 ₁ is rotationally driven by the rotary drive means 11, the movable base 8 is moved. While the horizontal posture of the horizontal plate portion 8a is maintained, it is driven so as to draw a circular motion in the vertical plane orthogonal to the rotation axis of both the rotary members 7 ₁ and 7 ₂ .

The tray 9 is formed in a rectangular flat plate shape, and a plurality of recesses 19 for fitting and mounting a plurality of paint containers 12 are provided on the upper surface of the tray 9. The tray 9 is pivotally supported on the movable table 8 via a support shaft 20 having a horizontal axis line that is orthogonal to the axis lines of the connection shafts 18 ₁ and 18 ₂ . That is, the upper surface of the horizontal plate portion 8a of the movable table 8 is provided with a raised portion 21 extending in a direction orthogonal to the axes of the connecting shafts 18 ₁ and 18 ₂ , and the lower surface of the tray 9 has the raised portion 21 at both ends. The brackets 22 and 22 are provided so as to be sandwiched between the brackets 22 and 22. By inserting the support shaft 20 whose both ends are supported by the brackets 22, into the raised portion 21, the tray 9 is pivotally supported on the movable table 8 via the support shaft 20.

Both springs 10 ₁ and 10 ₂ are arranged on the horizontal plate portion 8 a of the movable table 8 on both sides of the support shaft 20, and the lower ends of both springs 10 ₁ and 10 ₂ are tray 9 Are fixed on the horizontal plate portion 8a at the positions corresponding to the corners on the diagonal line. Thus, the natural lengths of both springs 10 ₁ and 10 ₂ are set so that there is a space between the tray 9 and the bottom of the tray 9 when the tray 9 is in the horizontal posture, and the tray 9 is supported. When tilted to one side around the axis of the shaft 20, _{one of} the springs 10 ₁ and 10 ₂ comes into contact with the bottom of the tray 9 and is compressed, and the repulsive force causes the tray 9 to rotate around the axis of the spindle 20. Therefore, it will be elastically urged in the opposite direction to the above.

Next, the operation of this embodiment will be described. When the rotary drive means 11 is operated with one or a plurality of coating containers 12 placed on the tray 9, the movable table 8 is moved to both rotary members 7. _It can be operated by drawing a circular motion in the vertical plane orthogonal to the axis of rotation of ₁ , 7 ₂ . On the other hand, the tray 9 pivotally supported by the movable table 8 via the support shaft 20 is left and right of the support shaft 20 due to the circular movement of the movable table 8 due to the left and right weight imbalances of the support shaft 20. The tray 9 is tilted to one side, and one of the both ridges 10 ₁ and 10 ₂ exerts elastic force as the tray 9 is tilted, and the tray 9 is flipped up to the other side. The tilting motion of the shaft 20 to the left and right is repeated.

Therefore, the paint container 12 on the tray 9 is given a combined motion of a circular motion in the vertical plane and a tilting motion of the support shaft 20 to the left and right, and the paint container 12 The coating material of (3) will be sufficiently stirred in a short time.

Moreover, since both rotary members 7 ₁ and 7 ₂ are formed in a disk shape, they function as a flywheel, and increase the inertia moment when the movable table 8 draws a circular motion. Therefore, a smooth circular movement can be performed. Further, the tray 9 pivotally supported by the movable table 8 repeats frequent swinging movements as the left and right weights of the support shaft 20 become unbalanced, so that the tray 9 is placed on the tray 9. The coating container 12 to be placed is arranged so that the weight balance is inclined in either direction, but the tray 9 is provided with a support shaft 20 having an axis orthogonal to the rotation axes of the rotating members 7 ₁ and 7 _2. Since it is pivotally supported by the movable table 8, the position of the support shaft 20 hidden by the tray 9 can be roughly estimated, and it is easy to arrange the paint containers 12 ... In consideration of the weight balance. is there.

FIG. 5 shows a second embodiment of the present invention, in which the tray 9 is movable via a spindle 20 having a horizontal axis diagonally intersecting with the axes of the connecting shafts 18 ₁ and 18 _2. It is pivotally supported on the stand 8.

According to the second embodiment, it is difficult to estimate the position of the support shaft 20 with respect to the tray 9, and therefore a plurality of paint containers 12 ... Can be appropriately arranged on the tray 9. , The weights of the trays 9 on the left and right of the support shaft 20 are likely to be unbalanced, so that the tray 9 can be easily oscillated, which is sufficient for the paint containers 12 ... A stirring motion is provided and efficient stirring is achieved.

FIG. 6 shows a third embodiment of the present invention, in which a pair of disc-shaped rotating members 7 ₁ ′ and 7 ₂ ′ rotate on the base 6 at a position deviated from the center thereof. It is rotatably supported, and the rotary drive means 11 is connected to one of the rotary members 7 ₁ ′. The movable table 8 is connected to both rotary members 7 ₁ ′ and 7 ₂ ′ via connecting shafts 18 ₁ and 18 ₂ .

According to the third embodiment, since the center of gravity of the rotating members 7 ₁ ′ and 7 ₂ ′ is displaced from the axis of rotation, the rotary drive means 11 moves one rotor member 7 ₁ ′ to a constant torque. When a rotational driving force is applied to the movable base 8 or the tray 9, the speed increases when the position of the center of gravity descends, and decreases when the position of the center of gravity increases. More efficient stirring can be achieved by increasing or decreasing the motion speed in one circular motion.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the present invention described in the scope of claims for utility model registration. It is possible to make design changes.

For example, springs 10 ₁ and 10 ₂ are fixed to the tray 9 on the left and right of the support shaft 20, and the springs 10 ₁ and 10 ₂ are moved along with the swing of the tray 9 around the support shaft 20. You may make it contact | abut and repel it on the upper surface.
