Description

[0001]
[Industrial applications]
The present invention relates to a shaker that swings and shakes in a seesaw shape, and more particularly to a shaker that can adjust the size of a seesaw type swing shake while looking at the seesaw type swing shake. In the field of molecular biology research, the present invention relates to a shaker which is particularly suitable for use in washing and decoloring gels and washing hybridization.
[0002]
[Prior art]
As shown in FIG. 4, an eccentric shaft 14 is slidably fitted in an eccentric long hole 13 provided in a vertically disposed rotating disk 12, and a vertically moving shaft is attached to the eccentric shaft 14. The shaking table 4 is swingably shaken in a seesaw shape by the vertical movement of the vertical moving shaft 3.
[0003]
[Problems to be solved by the invention]
However, the shaker of FIG. 4 adjusts the vertical movement width of the vertical movement shaft 3 by manually loosening the fitting of the eccentric shaft 14 to the eccentric long hole 13 and then sliding the same. There is a problem that when the swinging vibration is adjusted to be large or small, it is necessary to stop the operation once, loosen the eccentric shaft 14 and slide the eccentric shaft 14.
[0004]
Furthermore, since it is necessary to loosen the eccentric shaft 14 and slide it by putting a hand in the body, it is not easy to adjust the rocking and shaking width of the seesaw shape, and it is still difficult to adjust it. There is a problem that it takes a lot of time to obtain a seesaw-shaped oscillating shake optimal for the quality and quantity of the sample liquid S.
[0005]
[Means for Solving the Problems]
According to the present invention, a vertically moving shaft 3 is attached to one end of a swinging rod 2 which swings in a seesaw shape based on an intermediate fulcrum shaft 1, and an upper end of the vertically moving shaft 3 is pivoted below one side of a shaking table 4. In a shaking machine in which the shaking table 4 is rocked and shaken in a seesaw shape by the vertical movement of the vertical moving shaft 3 while being worn, the hole of the rocking rod 2 into which the fulcrum shaft 1 is inserted is formed. The fulcrum shaft 1 is formed in the elongated hole 6 and supported by the adjusting motor 7 so as to slide with a screw cylinder 9 screwed into a left-right helical shaft 8 rotated forward and reverse by an adjusting motor 7. The fulcrum shaft 1 is moved left and right by starting the adjustment motor 7 while observing the seesaw-shaped swinging vibration of the sample liquid S in the container 4a to adjust the seesaw-shaped swinging vibration of the sample liquid S to a large or small size. Thus, such a problem was solved.

BEST MODE FOR CARRYING OUT THE INVENTION
This will be described below with reference to the drawings.
[0007]
A disk 17 that rotates in the vertical direction by a driving motor 16 is provided in the shaker main body 15, and a horizontal rod 19 that pivots in a vertical direction with a lever 18 attached to an eccentric point of the disk 17 is provided. Provided on the disk 17. Reference numeral 20 denotes a stop point shaft for rotating the horizontal rod 19 in a sector shape. The fan-shaped rotating end of the horizontal rod 19 is connected to one end of the swinging rod 2 with the connecting rod 21 and the rotor 10 interposed therebetween, and the fulcrum shaft 1 is inserted into the elongated hole 6 provided in the middle of the swinging rod 2, One end of the shaft 1 is screwed to a screw shaft 8 that rotates forward and reverse by an adjusting motor 7 and attached to a screw cylinder 9 that reciprocates, and the other end of the swinging rod 2 is attached to a vertical moving shaft 3. The upper end of the shaver is protruded from the upper surface opening of the shaking machine body 15 and is pivotally mounted 5 below one side of the shaking table 4. Reference numeral 22 denotes a center support shaft of the shaking table 4, reference numerals 23a and 23b denote spring mechanisms on both sides for buffering the movement of the shaking table 4 to prevent backlash of the shaking mechanism, and reference numeral 24 denotes a horizontal rod 19 and a swinging rod 2. In addition to mounting the stop point shaft 20, the adjusting motor 7 and the mounting plates 25a, 25b for the screw shaft 8, a vertical U-shaped frame 11 for guiding the rotor 10 is mounted. 8, a long hole 24a is provided. Reference numeral 26 denotes a support plate that supports the other end of the fulcrum shaft 1 with a long hole 26a. A container 4 a containing the sample liquid S is fixed on the shaking table 4.
[0008]
When the driving motor 16 is started and the disk 17 is rotated, the horizontal rod 19 is rotated in a sectoral manner based on the stop point shaft 20 by the rotation of the lever 18 with the vertical movement, and the connecting rod 21 is rotated. The swinging rod 2 is interlockingly swung in a seesaw shape on the basis of the fulcrum shaft 1 with the child 10 interposed therebetween, and the vertical motion shaft 3 is moved up and down to swing the shaking table 4 in a seesaw shape.
[0009]
In order to adjust the magnitude of the shaking of the sample solution S in the container 4a on the shaking table 4, the adjusting motor 7 is operated in the forward or reverse direction while operating. Then, when the screw shaft directly connected to the adjusting motor 7 is rotated forward or backward and the screw shaft 9 screwed together with the screw shaft 9 is moved to the left and right on the fulcrum shaft 1 of the seesaw type swing, and the swing of the vertical movement shaft 3 is increased or decreased. Accordingly, the shaking table 4 is operated to adjust the size of the seesaw-shaped rocking shaking while watching the state of the sample liquid S.
[0010]
In this case, when the fulcrum shaft 1 is moved toward the vertical movement shaft 3 as shown in FIG. 3A, the seesaw-shaped swing is reduced, and the fulcrum shaft 1 is moved toward the rotor 10 as shown in FIG. The swing width becomes larger when moving to.
[0011]
【The invention's effect】
As described above, according to the present invention, when the adjusting motor is rotated forward or backward, the fulcrum shaft is smoothly moved left and right while seeing the seesaw-shaped shaking shaking of the sample liquid in the container on the shaking table during operation. As a result, it is possible to adjust the magnitude of the seesaw-shaped rocking shaking of the sample liquid.
[0012]
This produces an effect that a seesaw-shaped rocking shake optimal for the quality and quantity of the sample liquid in the container placed on the shaking table can be obtained quickly without skill.
