Description

The present invention relates to an agitating / defoaming device for an agitated material used for agitating and defoaming the agitated material accommodated in a container.

Technology background

Conventionally known as materials that dislike air bubbles (stirred materials) depending on the purpose of use, such as epoxy adhesives, coating materials and other electronic parts related materials, and conductive (gold and silver, solder, etc.) pastes, solder pastes and other liquid crystal As a device used when agitating and defoaming a dental impression material (alginic acid), a container containing the material to be stirred, a substantially cylindrical container holder holding the container, and one piece Alternatively, a support base formed in the shape of an arm or an arch provided with a plurality of container holders, a first rotation drive mechanism composed of a gear or pulley and a belt for driving the container holder to rotate, and a support base revolving. 2. Description of the Related Art An apparatus is known that includes a second rotational drive mechanism that drives, a first rotational drive mechanism, and a motor that serves as a drive source for the second rotational drive mechanism (references: JP 2001-125707 A). No. 159698).

The above apparatus stores a desired material to be stirred in a container and holds the container in the container holder, and then revolves the support base via the second rotational drive mechanism by the drive source and the first rotational drive mechanism. Through which the container holder is driven to rotate. As a result, a flow rotating in the radial direction of the container is generated in the material to be stirred contained in the container to stir the material to be stirred, and the material to be stirred is pressed against one inner side of the container by the centrifugal force at the time of rotation. And used to defoam bubbles in the material to be stirred.

However, in order to stir and degas the stirrer by setting the rotation speed of the container holder to rotate and revolve according to the type of stirrer, Depending on the type, the rotation speed of the container holder rotates and revolves differently, and the radial rotation in the container and the centrifugal force applied to the container also differ. The held container slips and the container rotates in the container holder.

For this reason, the stirring effect | action of a to-be-stirred material and the defoaming effect | action of an internal bubble cannot be performed reliably.

Therefore, a groove is formed on the outer periphery of the upper part of the container held by the container holder in an equally distributed manner, and a claw part that fits into the groove is formed on the upper part of the container holder to prevent emptying due to slipping of the container and to be stirred. The agitation action and the defoaming action of the internal bubbles are performed (Design Registration No. 1050943).

Problems to be solved by the invention

However, the conventional slipping means of the container by the above-mentioned slip has a drawback that the manufacturing process is complicated and costly because a groove must be formed in the container and a claw portion must be formed in the container holder. .

In addition, since the container is fixed on the upper side of the container holder, the container can be prevented from being idle, but the stability on the bottom side is insufficient. Therefore, fine vibrations are given to the stored material to be agitated located on the bottom side during the rotation and revolution of the container, and optimal agitation and defoaming action is performed for materials related to electronic parts that do not like bubbles. There was a drawback that it was not possible.

In particular, in the case of a to-be-stirred material having a viscosity, there is a defect that defoaming and stirring action are insufficient.

Accordingly, the present invention provides a stirring / defoaming method and apparatus for a stirrer that can eliminate any slippage of the container in the container holder and more suitably stir / defoam all types of the stirrer. The task is to do.

Means for solving the problem

That is, the present invention provides a solution means for solving the above-mentioned problems, as described in claim 1, a container in which a material to be stirred is stored, a container holder for holding the container, and a container holder In the stirring and defoaming device for the material to be stirred, comprising a support base provided with a first rotational drive mechanism for revolving the support base, and a second rotational drive mechanism for rotationally driving the container receiver, The outer bottom surface of the container, the outer peripheral surface and / or the inner bottom surface and the inner peripheral surface of the container holder prevent the container from sliding in the container holder when the support base is driven to rotate and / or when the container holder is driven to rotate. A slip prevention means is provided.

Effects and effects of the invention

Next, the operation of the stirring / defoaming apparatus having the above configuration will be described.

First, a desired material to be stirred is stored in a container, and the container is held in a container holder. At this time, the bottom surface and the outer peripheral surface of the container are provided with anti-slip means for preventing the container from sliding in the container holder when the support base is driven to revolve and / or when the container holder is rotated. In addition, the container is securely held without slipping in the container holder.

Moreover, since the container is held in the container holder on both the bottom surface side and the side peripheral surface side, it does not slide or vibrate.

Therefore, when the container holder rotates while revolving the support base, each rotation is reliably transmitted to the container held by the container holder.

And, in the container, radial flow and vertical convection are generated, the agitated material stored is agitated, and the internal bubbles by being pressed by the centrifugal force are surely degassed. Can do.

Also, depending on the type of the material to be stirred, the number of revolutions of the support base and the number of rotations of the container holder are changed (for example, the number of revolutions of the support base and the number of rotations of the container holder are controlled (the number of rotations during revolution) Even if the rotation direction is set to 0 or the rotation direction is reversed with respect to the revolution direction), the change can be reliably transmitted to the container. Become.

In addition, even in the case of highly viscous materials to be stirred, the container can be rotated without slipping in the container holder due to vibrations caused by the movement of the material to be stirred. It became possible to do.

In addition, when the desired material to be stirred is stored in the container and the container is held in the container holder, the container holder has a bottom surface and an inner peripheral surface. By providing anti-slip means for preventing the container from slipping, the same actions and effects as described above can be obtained.

Furthermore, the container can hold the container in the container holder more strongly by providing anti-slip means on both the bottom surface side and both sides of the side surface and the bottom surface and the inner periphery of the container holder.

As described above, the present invention can surely perform the stirring and defoaming action in correspondence with all kinds of materials to be stirred, and can be used in a wide range.
