Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a shaker having both functions of linear reciprocating operation and turning operation.

<Problems to be solved by the present invention> Conventional shakers used for shaking culture and the like are of two types, that is, a type of linear reciprocating operation and shaking, and a type of rotating operation and shaking, Depending on the sample, it may be necessary to obtain separate data for both types of shaking, and it is necessary to provide two types of shaker. However, there is a problem that installing two models individually increases both cost and equipment space.

SUMMARY OF THE INVENTION The present invention provides a shaker that can be switched between linear reciprocating operation and swivel operation with a simple operation, and is robust and does not cause a failure, and aims to solve such problems.

<Structure of the Invention> The present invention relates to a track provided on a machine body by fitting a revolving rotary shaft vertically installed on a horizontal rotating disk mounted in the machine body and a vertically long slot provided in the middle of the revolving rotary shaft. A plate that can reciprocate in the lateral direction, a shaking table that is fitted and mounted on the plate and can reciprocate in the longitudinal direction of the plate, and a long hole of the plate on the shaking table. A long hole which is superposed and fitted to the swivel rotary shaft and a long hole which is vertically fitted to the intermediate upper surface of the plate and which is fitted to a vertical shaft for engagement are provided in parallel, and are provided on the shaking table. A switching plate is mounted and attached in a freely slidable manner, and a long hole into which the rotary shaft is fitted is released at a position where the vertical shaft is sandwiched and engaged by a stop portion on the switching plate, and the rotary shaft is fixed by another stopper. It is configured by providing a window hole with a shape that releases the long hole where the vertical shaft fits at the position where it is clamped and fixed. The vertical axis is engaged by the ride operation, and the rotary table is reciprocally operated integrally with the plate while the turning rotary shaft can freely move within the long hole of the shaking table, and the reverse sliding operation of the switching plate is performed. Fix the swivel rotary shaft to one point in the long hole of the shaking table, and release the engagement between the plate and the shaking table to allow the vertical axis to move freely in the long hole. The combination of the motion and the motion of the shaking table that reciprocates in the longitudinal direction on the plate causes the shaking table to rotate along the circular motion trajectory of the rotation axis of rotation.

<Example> An example will be described below with reference to the drawings.

On the horizontal rotating disk 3 which is rotated by the transmission mechanism provided inside the machine body 1, the adjusting frame 4 is provided in the length from the center of the disk to the outer edge.
Is attached, and the turning rotary shaft 2 is installed vertically so that the eccentricity can be adjusted to a large or small amount by moving the adjusting frame 4 in the adjusting frame.

Reference numeral 5 denotes a plate, which is provided with a long hole 6 formed in the longitudinal direction in the middle and slightly toward the side, and is provided with rolls 7 which rotate vertically at the four corners of the front and rear side vertical walls.
While being fitted to each other, each roll 7 is fitted to four rails 8 provided at front and rear positions inside the machine body 1 to reciprocate laterally.

Reference numeral 9 is a shaking table that is fitted and mounted on the plate, and is a plate 5
The rotation shaft 2 has a long hole 6a at a position where it overlaps with the long hole 6 of
And the rails 10 provided inside the left and right hanging walls are fitted to the rolls 11 at the four corners attached to the left and right hanging walls of the plate 5 so as to vertically rotate, and reciprocate vertically on the plate 5. I am trying. In addition, 12a is a vertical shaft provided at the symmetrical position of the long hole 6 of the plate 5, 12b is a long hole of the same length parallel to the long hole 6a formed at the relative position to the vertical shaft 12a of the shaking table 9. ,
The vertical shaft 12a is fitted in the long hole 12b to expose the upper part, and the engaging means between the plate and the shaking table is constituted by engaging the switching plate described later.

A switching plate 13 is mounted and mounted on the shaking table 9. The switching plate 13 has a bottom portion having a length which overlaps with the long holes 6a and 12b in parallel with the central portion and is located at an apex position opposite to the bottom portion. There are provided two substantially symmetrical triangular window holes 15a and 15b each of which forms stop portions 14a and 14b of a size capable of sandwiching and fixing the turning rotary shaft 2 and the vertical shaft 12a. The interval is such that the turning shaft 2 can freely move in the elongated hole 6a along the bottom portion of the window hole 15a at a position where the stop 14b sandwiches the vertical shaft 12a, and the stop 14a turns. The vertical shaft 12a is provided with such a size that the vertical shaft 12a can freely move in the elongated hole 12b along the bottom portion of the window hole 15b at a position where it is sandwiched and fixed. In addition, 16 is a switching lever protrudingly attached to the front side of the switching plate 13, 17 is a receiving roll of the switching plate 13 provided on the shaking table 9, and the switching plate 13 is fitted to the front and rear side receiving rolls 17. By operating the switching lever 16, the two states can be switched by sliding in the lateral direction. 18 is a spring-loaded stopper,
As shown in the figure, the receiving holes 19a, 1 provided on the upper surface of the shaking table 9
The switching plate 13 is elastically fixed at the left and right switching positions by being fitted to the 9b.

Reference numeral 20 designates a pedestal that is mounted in a floating manner on the shaking table 9 with the switching plate 13 interposed therebetween, and 21 is a mounting screw thereof. Further, 22 is a leaf spring attached to the inner surface of the rear rising wall of the gantry 20, and 23 is a cam type operator attached to the front rising wall of the gantry 20, which is a test tube stand mounted on the gantry 20. It is configured such that (not shown) is sandwiched and fixed between the leaf spring 22 and the operating element 23.

<Operation of the Invention> As shown in FIGS. 1 and 3, when the switching lever 16 is moved to the reciprocating side (left side in the drawing), the switching plate 13 moves in the same direction, and the stop portion 14b sandwiches the vertical shaft 12a. By engaging with each other, the plate 5 and the shaking table 9 are integrated in a fixed state, and at the same time, the swiveling rotary shaft 2 is released from the stop portion 14a and becomes a position along the bottom portion of the window hole 15a so that the inside of the long hole 6a is free. As shown in FIG. 8, the longitudinal force of the circular motion vector of the turning rotary shaft 2 does not act on the plate 5 and the shaking table 9, and only the lateral force acts on the plate. 5 and shaking table 9
As a result, the two integrally reciprocate linearly in the lateral direction along the orbit, so that the gantry 20 and the sample mounted on the gantry 20 are reciprocally shaken.

When switching to swing shaking, the switching lever 16 is moved to the swing side (right side in the drawing) as shown in FIG. Then, the stopper 14a sandwiches and fixes the swivel rotary shaft 2 and the vertical shaft 12a.
Is released from the engagement of the stop portion 14b, the fixation between the plate 5 and the shaking table 9 is released, and the vertical shaft 12a can move freely in the long hole 12b. It becomes possible to reciprocate in the vertical direction. The plate 5 receives the circular motion of the swivel rotary shaft 2 as in the case of reciprocal shaking and continues the reciprocal motion in the lateral direction, but the shaking table 9 is stopped by the stopper 14a of the switching plate 13 at the rotary rotary shaft 2 Since it is fixed by sandwiching it in the center of the long hole 6a, as shown in FIG. 9, while moving vertically on the plate 5 which continues reciprocating in the horizontal direction, it is possible to turn by the combination of the vertical and horizontal movements. The sample is swung with the same orbit as the circular motion of the rotary shaft 2, and the sample is swung and shaken.

<Effects of the Invention> As described above, the shaker of the present invention receives the revolving rotary shaft on the plate which receives the revolving rotary shaft in the long hole and reciprocates in the lateral direction. A shaking table that can reciprocate in the vertical direction is fitted and mounted with a hooking and detaching hooking means, and switching between the hooking and unhooking and the fixed release of the shaking table and the turning rotary shaft is performed with one touch. Since a switching plate that can be used is installed, one shaker can be used as a shaker for reciprocating operation and swing operation with easy and immediate switching, and effective utilization of equipment cost and equipment space is possible. This brings about an effect that the working efficiency can be improved while being realized.
