Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a shaking machine having both functions of linear reciprocating operation and rotating operation.

<Problems to be solved by the present invention> Conventionally, there are two types of shakers used for shaking culture, etc.: one type that operates in a linear reciprocating manner for shaking, and the other type that operates in a rotating manner for shaking. Therefore, it may be necessary to adopt these two types of shaking methods separately to obtain shaking-related data on the progress and results of culture samples. However, there is a problem in that installing two types of shaking machines increases both cost and equipment space.

The present invention aims to solve these problems by providing a relatively inexpensive shaker that can be used in one model by switching between linear reciprocating operation and rotating operation with a simple operation without taking up much space. That is.

<Structure of the Invention> In the present invention, a disk 8 rotated by a motor 2 is horizontally mounted on the upper plate 1a of the box-shaped machine body 1, and a bearing 10 is fitted on the side circumference of the disk 8 so as to be movable and adjustable. The horizontally elongated hole 18 formed in the support truck 16 is fitted into the rotary shaft 11, and the support truck 16 is placed on the upper plate 1a. A shaking table 13 having a horizontally elongated hole 14 that overlaps with the hole 18 and fitting and mounting on the rotating shaft 11 is provided, and the shaking table 13 and the support cart 16 are provided.
A spring member 29 is stretched between one side surface, and a guiding slope 22 is provided on the upper surface parallel to one longitudinal side of the horizontally elongated hole 14 of the shaking table 13.
22 and a U-shaped groove 23 between which the pivot shaft 11 is sandwiched and released, and a switching plate 21 that moves forward and backward is provided.

<Example> Examples will be described below based on the drawings.

As shown in FIG. 1, a motor 2 with a reduction gear is installed in one corner of a box-shaped machine body 1, and a pulley 4 that receives the power of the motor 2 by a V-belt 3 is installed in the center of the machine body 1.
A rotary shaft 7 supported by upper and lower bearings 5 and 6 is installed vertically. The upper end of the rotating shaft 7 protrudes above the upper plate 1a of the body 1 and supports a disk 8. Elongated hole 9a attached to the upper surface of one radius of the disk 8
A pivot shaft 11 with a bearing 10 fitted around the upper side is inserted into the fixing member 9 provided with the shaft. The pivot shaft 11 moves within the elongated hole 9a so that the pivot diameter can be adjusted to a larger or smaller value. 12 is a fixing nut.

The shaking table 13, which is rectangular in plan view and placed on the box-shaped machine body 1, has a horizontally long hole 14 in its center, and the horizontally long hole 14 is fitted to the pivot shaft 11, and hanging walls 15 are folded down on all sides. The inner hanging wall 30a of the stand 30 is formed and removably mounted thereon, and is hooked thereto.
A slightly smaller support cart 16 placed directly below the shaking table 13 has side walls 16a facing each other on both sides,
16a, and guide rollers 17 whose upper half protrudes above the support cart 16 are attached to four outer ends of the side walls 16a, 16a.
The shaking table 13 is supported on the upper surface of the holder. Note that the guide roller 17 is arranged parallel to the longitudinal direction of the horizontally elongated hole 14 .

In addition, the outer surface of the side wall 16a and the side wall 1 of the shaking table 13
Spring members 29, 29 are stretched between the end faces on the 6a side to prevent the shaking table 13 from rolling and sliding.

The support cart 16 has a horizontally long hole 18 in the center that overlaps with the horizontally long hole 14 of the shaking table 13, and is fitted to the rotating shaft 11. Wheels 19 for running are attached to four ends, and these wheels 19 are mounted on parallel rails 2 provided on the upper plate 1a of the fuselage 1.
It is installed in 0.20.

As shown in FIG. 3, 21 is a thin plate-shaped switching plate mounted parallel to one end surface on the longitudinal side of the horizontally long hole 14 of the shaking table 13 so as to be able to move forward and backward; A bearing 10 is provided at the center position between the open guide slopes 22, 22 and the slopes 22, 22.
A U-shaped groove 23 is provided with a size that is large enough to hold the. Guide rails 24, 24 are provided on both sides of the switching plate 21.
A connecting rod 25 fitted to the rear end and attached to the rear end.
is connected to one side of the operating rod 27 which is fixed to the shaking table 13 at the fulcrum 26, and moves forward into the U-shaped groove by extension of the rod 28a of the electromagnetic cylinder 28 connected to the other side of the operating rod 27. The bearing 10 is clamped at 23, and the bearing 10 is released by the reverse operation.

In addition, as shown in FIG.
Spring members 29, 29 are tensioned between the support cart 17 and the shaking table 13, so that the shaking table 13 is normally kept on the center of the support cart 16 and does not slide on the rollers 17.

<Operation of the Invention> Next, the operation of switching the shaking machine of the present invention between linear reciprocating operation and rotating operation will be explained.

(1) When the shaking machine of the present invention is to be operated in a linear reciprocating manner, the rod 28a of the electromagnetic cylinder 28 is contracted by operating the changeover switch (not shown) as shown in FIG. 4, and the changeover plate 21 is moved back. Then, the bearing 10 is released from being held by the U-shaped groove 23 and the motor 2 is driven. The motor 2 is driven by rotating the disk 8 via the rotating shaft 7, rotating the rotating shaft 11 set up on the disk 8, and rotating the horizontally elongated holes 14, 18 fitted into the rotating shaft 11.
This causes the support cart 16 and the shaking table 13 to move in a linear reciprocating motion. This relationship can be understood from the explanatory diagram of FIG. In other words, when the pivot shaft 11 moves in the longitudinal direction of the middle horizontally elongated holes 14 and 18 shown by the solid lines, the support cart 16 and the shaking table 13 do not move, but when the pivot shaft 11 moves toward the center of the horizontally long holes shown by the upper and lower dotted lines. In the process of turning toward the target, the shaking table 13 is pushed, resulting in a linear reciprocating operation in the direction shown by the straight arrow in FIG. 5. Note that the support cart 16 has wheels 19 on parallel rails 2.
0, and the shaking table 13 is prevented from sliding on the support cart 16 by the tension of the tensioned spring members 29, 29, so the shaking table 13 is securely mounted on the support cart 16. Linear reciprocating operation.

(2) When rotating the shaker of the present invention,
As shown in FIG. 6, by operating a changeover switch (not shown), the rod 28a of the electromagnetic cylinder 28 is extended, the changeover plate 21 is advanced toward the oblong hole 14, and the bearing 10 is moved to the guide slope 22, U-shaped groove 2 while guiding it to the center at 22
3, the motor 2 is operated after the bearing 10 is clamped. The shaking table 13 is integrated with the rotating shaft 11 to perform a rotating operation. As shown in FIG. 7, this turning operation is realized by a combination of vertical and horizontal linear reciprocating operations in which the shaking table 13 operates in a direction perpendicular to the reciprocating motion of the support cart 16.

In this case, by setting the tension of the spring members 29, 29 that integrate the shaking table 13 with the support cart 16 to be weaker than the turning force of the turning shaft 11, the shaking table 13 can be reliably rotated. I will do it.

In addition, in both of the above-mentioned linear reciprocating shaking and rotating shaking, the magnitude of the amplitude can be adjusted immediately by simply moving and adjusting the insertion position in the elongated hole 9a of the rotating shaft 11.

Further, although the switching plate 21 is formed in the shape of a thin plate in the embodiment, it may be replaced by a system in which a guide portion and a U-shaped groove are formed using two bars or the like.

<Effects of the Invention> As described above, in the shaking machine of the present invention, the support cart and the shaking table, which support the pivoting shaft in the horizontally elongated hole, can be connected to the U-shaped groove by advancing and retreating the switching plate provided on the shaking table. By the simple operation of switching between pinching and releasing the pivot shaft, it is possible to easily use the device for linear reciprocating shaking and rotating shaking.

Further, in both linear reciprocating shaking and rotating shaking, the amplitude can be adjusted to be large or small by adjusting the movement of the rotating axis.

Further, during linear reciprocating shaking, the tension of the spring member allows the shaking table to move in a linear reciprocating manner accurately in accordance with the movement of the support cart.

Moreover, it has the advantage of being simple in structure and can be provided at low cost.
