Description

[Detailed description of the invention] The present invention relates to the structure of a stirring device, and the mixed material filled in a flexible mixer made of a flexible sheet is diffused and mixed by shaking the bottom of the mixer. This invention relates to the structure of a stirring device of this type.

The mixing motion in a stirring device is generally classified into convection mixing, shear mixing, and diffusion mixing.

Among these, diffusion mixing has excellent performance as soft mixing, which does not cause damage to the mixture such as destruction of particles or bending of fibers.

As a stirring device that can efficiently perform such diffusion mixing, a flexible mixer made of a flexible sheet such as a canvas reinforced rubber sheet is filled with mixed materials, and a rocking motion is installed at the bottom of the mixer. A stirring device has been proposed that accelerates the mixture and changes its speed, direction, etc. and scatters the mixture in random directions, thereby performing mixing in a short time.

A conventional stirring device of this type has a fixed frame supporting a swinging frame that can be turned upside down, a mixer consisting of a lower flexible part and an upper rigid part attached to the swinging frame, and a mixer comprising a lower flexible part and an upper rigid part. It has a structure in which a swinging plate that is driven to swing is connected to the bottom of the flexible part, and after diffusing and mixing the mixed material supplied from the top end of the mixer, the swinging frame is reversed and the lid at the top end of the mixer is removed. The mixture was then taken out.

However, with such conventional stirring devices, it is necessary to stir a certain mixture and then transfer it to another container, etc., which takes time, so continuous stirring is not possible. First, there was the problem of low operating rates. There was also the problem that dust was thrown up when transferring to another container, creating a poor working environment.

The purpose of the present invention is to solve the problems of the conventional technology, to be able to carry out the next stirring in a short time, to greatly improve the operating rate, and to prevent confusion by transferring in a sealed state. It is an object of the present invention to provide a diffusion mixing type stirring device capable of preventing dust generation.

The present invention has a configuration in which another container is brought into sealing contact with the periphery of the upper opening of the mixer in an inverted position, and after stirring is completed, the container can be taken out with the mixture still filled and the container filled with a new mixed material can be attached. According to
This aims to achieve the above objectives.

That is, according to the present invention, a swinging frame that can be turned upside down is supported on a fixed frame, a mixer consisting of a lower flexible part and an upper rigid part is attached to the swinging frame, and the flexible In a stirring device of a type that performs mixing by applying a rocking motion to the bottom of a flexible part, the mixer has an open top end, and a container with an open top end that is abutted on the periphery of the top end in an inverted position, further comprising: a stopper provided on the swinging frame to position the container by coming into contact with a circumferential surface of the container; and a pressing mechanism provided on the swinging frame to bring the container into sealing contact with the mixer; A stirring device is provided that is configured to attach and detach the container while the frame is inverted.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

1 to 3, a fixed frame 2 installed on a floor 1 has a swinging frame 3 with its support shaft 4,
4 so that it can be turned upside down. A sprocket 5 is fixed to one support shaft of this swing frame. Two cylinders 6, 6 are attached to one side of the fixed frame 2 (the side of the sprocket 5), and a chain 7 wound around the sprocket 5 is connected between the rod tips of each cylinder. Therefore, by driving each cylinder 6, 6, the swing frame 3 is vertically reversed to the normal rotation position shown in FIG. 1 and to the reverse rotation position shown in FIG. 3.

A mixer 8 is attached to the swing frame 3. The mixer is open at the top and consists of a lower flexible part 9 and an upper rigid part 10. The flexible portion 9 is made of a rubber sheet with a reinforcing layer embedded therein, such as canvas, and is attached to the rigid portion 10 in a sealed manner at its upper peripheral edge.

A swinging member 11 is attached to the bottom of the flexible portion 9, and the swinging member 11 is controlled by a motor 12 attached to the lower part of the swinging frame 3 and a swinging plate 13 attached to the output shaft of the motor. It is designed to give a rocking motion to the This rocking motion imparts rocking motion to the flexible portion 9, thereby accelerating the mixed material in the mixer 8, changing its speed and direction, and scattering it in random directions for diffusion mixing.

A container 15 with an open top is abutted against the upper peripheral edge of the mixer 8 in an inverted position. In the normal rotation state or mixing position shown in FIG. 1, this container is pressed against the mixer 8 and in sealing contact, and in the reversed position shown in FIG. It's getting wet. That is, the container 15 is attached and detached using a stopper 16 and a pressing mechanism 17 mounted on the swing frame 3.

The stopper 16 is composed of a positioning member 18 having a substantially semicircular arc shape fixed to the swing frame 3 and a holding member 19 having a substantially semicircular arc shape removably attached to the front end of the positioning member. This causes the container 15 to be stopped at a concentric position with the mixer 8.

The pressing mechanism 17 is provided one set on each side of the swing frame 3, and includes a swingable pressing arm 20 and a cylinder 2 that drives the pressing arm.
It consists of 1.

Wheels 22 are provided on the bottom surface of the container 15,
As shown in FIG. 3, the container can be moved on the floor 1.

The method of using the stirring device described above is as follows.

In the normal rotation position shown in FIGS. 1 and 2, the motor 12 operates the swinging plate 13 to give a swinging motion to the flexible portion 9, and the mixed material 14 in the mixer 8
Diffuse and mix.

After the mixing is completed, the cylinders 6, 6 are operated to rotate the swinging frame 3 in the direction of arrow A in FIG. 2 to the inverted position shown in FIG. 3. At this inverted position, the pressing mechanism 17 is released (the pressing arm 20 is removed from the bottom surface of the container 15 as shown) and the container 15 is moved onto the floor 1. Next, by removing the holding member 19 (see FIG. 2) of the stopper 16, the container 15 is moved forward, that is, in the direction of arrow B in FIG.
Move it in the direction shown and it will be ready to be taken out. Therefore, the container 15 is removed while still being filled with the mixture 14.

When the next stirring is to be performed, another container 15 filled with the mixed material is inserted from the front and brought into contact with the positioning member 18 of the stopper 16, resulting in the state shown in FIG. 3. Next, the holding member 19 is hooked to the front end of the positioning member 18 to position the container 15. After that, the pressing mechanism 17 is driven,
The container 15 is slightly raised by the pressing arms 20, 20, and pressed against the upper end (lower end in the state shown in FIG. 3) of the mixer 8 to bring it into sealing contact. Thereafter, the cylinders 6, 6 are operated to rotate the swing frame 3 to the normal rotation position shown in FIGS. 1 and 2. In this normal rotation position, the mixed materials are moving into the mixer 8 by gravity, where the motor 12 is operated to perform mixing.

By repeating the same procedure thereafter, mixing can be carried out almost continuously one after another.

In the above embodiments, only diffusion mixing is performed by swinging the flexible portion 9, but if necessary, a rotary stirring blade (such as a conical rod) or a spiral rod may be installed in the mixer 8. It is also possible to use shear mixing and convection mixing by adding an additional device.

As is clear from the above explanation, according to the present invention, the next stirring can be carried out in a short time, and the mixture can be transferred in a sealed state without generating dust. As a result, a stirring device can be obtained which can greatly increase the operating rate and improve the working environment.
