  As shown in FIGS. 1 and 2, the stirrer 2 according to the present embodiment includes two disks 4 and 6 and three stirring containers 8. The two discs 4 and 6 are arranged so as to face each other in the vertical direction (a direction perpendicular to the paper surface in FIG. 1, the vertical direction in FIG. 2), and their rotation axes are arranged apart from each other in the horizontal direction in parallel. Has been.

  Here, the stirrer 2 according to the present embodiment is arranged and configured so that the two disks 4 and 6 face each other in the vertical direction as described above for convenience in the following description. However, the stirrer 2 may be arranged and configured such that the opposing directions of the two discs 4 and 6 face other directions other than the vertical direction.

  The two disks 4 and 6 and the three stirring containers 8 in the stirrer 2 are arranged in the case 22. As shown in FIG. 2, the case 22 includes a lower case 22a and an upper case 22b. The upper case 22b of the case 22 can be freely attached to or detached from the lower case 22a by an unillustrated attachment / detachment mechanism.

  Further, the agitator 2 includes a rotation shaft 24 arranged on the rotation axis of the disk 4. The rotary shaft 24 has an upper end connected to the lower surface of the disk 4 and is rotatably supported by a bearing member 28 supported by a support structure (not shown) in the lower case 22a. Is configured to receive a rotational driving force from an end (not shown) on the opposite side. Thereby, the disc 4 is rotationally driven.

  Further, the agitator 2 includes a rotation shaft 26 arranged on the rotation axis of the disk 6. The lower end of the rotary shaft 26 is connected to the upper surface of the disk 6 and is rotatably supported by a bearing member 29 supported by a support structure (not shown) in the upper case 22b.

  Further, as shown in FIGS. 1 and 2, the disc 4 is arranged on the disc 6 side at positions spaced apart at equal intervals in the circumferential direction on a pitch circle (not shown) with its rotation axis as the center. Three protruding pins 14a, 14b, 14c are arranged and fixed.

  Further, similarly to the disk 4, the disk 6 is also provided at each of the positions spaced apart at equal intervals in the circumferential direction on a pitch circle (not shown) with the rotation axis of the disk 6 as the center. Three pins 16a, 16b, 16c projecting to the side are arranged and fixed.

  Here, the above-described pins 14a, 14b, and 14c may be collectively referred to as pins 14 without attaching alphabets to these symbols. Similarly, the pins 16a, 16b, and 16c may be collectively referred to as pins 16.

  The size of a pitch circle (not shown) on which three pins 14a, 14b, 14c are arranged in the disc 4 and the size of a pitch circle (not shown) on which three pins 16a, 16b, 16c are arranged in the disc 6 The sizes are the same.

It is made to make a pair. That is, the combinations of the pins 14a and 16a, the pins 14b and 16b, and the pins 14c and 16c form a pair.

  Next, the three stirring containers 8 are disposed between the two disks 4 and 6. Each of the stirring containers 8 is formed with a storage portion 18 that stores a stirring target such as a liquid, powder, or granule. The accommodating part 18 is formed in a round hole shape having an opening on the disk 6 side and having a certain depth, and the opening part on the disk 6 side is tightly sealed by a lid 20.

  The lid 20 can be freely opened and closed by the user of the stirrer 2 when each of the three stirring containers 8 is detached from the stirrer 2 after the upper case 22b and the disc 6 are removed. It can be done.

  When each of the three stirring containers 8 is disposed between the disks 4 and 6, each pair of pins 14a and 16a, 14b and 16b, and 14c and 16c are combined. It is arranged at a position corresponding to each.

  In addition, as shown in FIG. 2, a gap is formed between the opposing surfaces of the disc 4 and the stirring vessel 8. The gap is formed by fitting a not-shown synthetic resin washer or the like having a thickness corresponding to the gap at the base of the pin 14. Also, a gap is formed between the opposing surfaces of the disc 6 and the stirring vessel 8 by fitting a not-shown synthetic resin washer or the like to the base of the pin 16. It has become.

  Each of the stirring containers 8 is formed with fitting holes 10 and 12 into which a pair of pins 14 and 16 corresponding to each of the stirring containers 8 are gently fitted. Each of the agitation containers 8 is rotatably supported by the pin 14 when attention is paid only to the relationship with the pin 14 fitted in the fitting hole 10. When attention is paid only to the relationship with the pin 16 fitted into the fitting hole 12, the pin 16 is rotatably supported by the pin 16.

  Thereby, as for the stirrer 2, each of the combination of pins 14a and 16a, 14b and 16b, and 14c and 16c which make a pair between both the disks 4 and 6 respond | corresponds to each of these combinations. Since the link mechanism is configured together with the stirring container 8, each of the stirring containers 8 is rotated by the two discs 4 and 6, and the horizontal direction is fixed as described below and in FIG. While maintaining the state of facing toward each other, they move on the same circumferential orbit.

  FIGS. 3A to 3H show the state in which the disks 4 and 6 in the stirrer 2 rotate once in synchronization with each other at every 45 degrees. In FIGS. 3A to 3H, the case 22 and the bearing members 28 and 29 are not shown in order to prevent complication of the drawing.

A stirring action can be exerted over the entire stirring target housed in the housing portion 18 of the container 8.

  That is, the stirrer 2 is configured such that when each of the stirring containers 8 moves on a circular path, the stirring object in the container 18 of the stirring container 8 is moved into the container 18 of the stirring container 8. While receiving force (centrifugal force) that can be pushed to one side, the direction of such force (centrifugal force) changes continuously in the horizontal plane, so stirring while moving along the inner wall surface. Will come to be.

  For this reason, the stirring object in the container 18 of the stirring container 8 is stirred so as not to remain at one place on the wall surface of the container 18. Thereby, as described above, the stirrer 2 can prevent the stirring object and its crystal components from sticking to the inner wall of the accommodating portion 18 of the stirring container 8 and the entire stirring object. A stirring action can be exerted over the entire area.

  Further, according to the stirrer 2 according to the present embodiment, the stirring container 8 can be attached by inserting the pair of pins 14 and the pins 16 into the fitting holes 10 and 12, respectively.
