DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container mounting plate on which a container can be mounted, and a container mounting plate rotatable around an axis, wherein the container mounting plate is eccentric to the axis. And a rotation drive shaft for rotating the container mounting plate around the axis of the support member by receiving a driving rotational force of a rotary drive source, and rotating the container mounting plate. The present invention relates to a liquid mixing device in a container provided with a rotation balance mechanism for taking a balance of rotation at the time.

[0002]

2. Description of the Related Art Conventionally, in the above-described liquid mixing apparatus in a container, a first rotation shaft and a second rotation shaft which are eccentric to each other are integrally provided to constitute the rotation drive shaft, and the first rotation shaft is provided. On the base, the second rotating shaft is rotatably mounted on the lower surface portion of the container mounting plate around the vertical axis, respectively, to constitute the rotation balancing mechanism. A balance weight was provided. When the liquids in a large number of containers are to be shaken at once, the first, second, third, etc., are spaced apart from the first container mounting plate supported by the support member via leg members. The container mounting plates are stacked, and in this state, the plurality of container mounting plates are rotated around the axis of the support member.

[0003]

However, in the above-mentioned conventional configuration, the rotary drive shaft and the support member are provided with balance weights, respectively, to constitute the rotary balance mechanism. When the weight is increased, the weight of the balance weight must be increased by an amount corresponding to the increase in the load applied to the support member, and there is a disadvantage that the weight of the device increases. In addition, in this case, the rotation drive shaft is rotatably mounted around the vertical axis on the lower surface of the first container mounting plate at the lowermost stage, with the first rotation shaft as a base. In a state where the second, third, etc. container mounting plates are stacked on the first container mounting plate supported by the support member at intervals via the leg members, all of the container mounting plates are placed. Because the plate was rotated, the upper-stage container placement plate was farther away from the support member, and the swing of the upper-stage container placement plate became larger. There is a disadvantage that it is difficult to balance the rotation when rotating the plate. The present invention solves the above-mentioned conventional disadvantages, can reduce the weight of the apparatus even if the number of container mounting plates is increased, and
It is an object of the present invention to provide a liquid mixing device in a container that can reliably maintain the rotation balance.

[0004]

In order to achieve the above object, a liquid mixing device in a container according to the present invention comprises: a rotary drive shaft comprising a crankshaft having a plurality of crankpins; A supporting frame for rotatably supporting the shaft about a vertical axis; connecting a plurality of container mounting plates to the plurality of crankpins in a horizontal position with a vertical space therebetween; The mounting plates are attached to the support frame via supporting members, respectively, and to constitute a rotation balance mechanism, the plurality of container mounting plates are arranged around the axis of the plurality of crankpins so as to be mutually balanced. The operation and effect are as follows.

[0005]

[Operation] In other words, since the crankshaft is rotated by receiving the driving torque of the rotation driving source, since it is configured as described above,
With the rotation, each of the plurality of container mounting plates rotates in a horizontal posture around each axis of the crankshaft and the support member, and the liquid in the containers on the plurality of container mounting plates is rotated. Shake. In addition, since the rotation balancing mechanism is configured to set the phase around the axis of the plurality of crankpins so that the plurality of container mounting plates are balanced with each other, no balance weight is required. In addition to this, even if the number of container mounting plates is increased, the rotation balance when rotating the container mounting plates can be obtained for each container mounting plate.

[0006]

Therefore, the balance weight can be eliminated, and when the number of container mounting plates is increased, it is possible to balance the rotation when rotating the container mounting plate for each container mounting plate. Therefore, even if the number of container mounting plates is increased, it is possible to reduce the weight of the apparatus and to provide a liquid shaking device in a container that can reliably maintain the rotational balance over all the container mounting plates. Was completed.
