Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a method for preparing powder and granular materials, in which a container containing powder and granular materials is fixed to a frame-shaped container case, and the container case is rotated to mix the powder and granular materials. This invention relates to a mixing device.

(Prior art and its problems) Utility Model Publication No. 58-1762 regarding this type of powder mixing device
No. 6 is known. In such prior art, a container with legs is housed in a frame-shaped container case, and single cylinders for pressing the container against the container case are provided at multiple locations.

Since the dimensions of the outer shell and leg length of the container are not necessarily constant, each cylinder partially presses the container to prevent it from wobbling within the case.

Further, since the cylinder protrudes outside the case, the rotation locus of the case becomes large, and the space in which the device is installed becomes large.

(Object of the Invention) An object of the present invention is to provide a powder mixing device that can securely fix a container in a container case and reduce the external size of the container case.

(Structure of the Invention) (1) Technical Means The present invention provides powder and granular materials, in which a container for accommodating powder and granular materials is fixed in a substantially frame-shaped container case, and the container case is rotated to mix the powder and granular materials. In the mixing device, external members for fixing the container are provided above and below the container to determine the external dimensions of the container, and the guide has a wall portion of a predetermined height at the lower end of the container case so that the external member fits into the container case. The wall of the guide is provided with an upwardly open tapered surface that guides the external member when the container is dropped into the guide, and the container is movable vertically by a hydraulic cylinder at the upper end of the container case. The apparatus is characterized in that a pressing member for pressing is provided, and the hydraulic cylinder is housed in a frame forming a container case.

(2) Fit the external member of the working container into the guide of the container case, and position the lower part of the container with the wall of the guide.

When the container is dropped into the guide, the external member is guided inside the wall of the guide by the Taber surface.

Since the hydraulic cylinder is housed within the frame of the container case, the outer size of the container case is reduced.

(Example) In FIG. 1 showing a powder/grain material mixing apparatus employing the present invention,
is a container containing powder and granular material. The container 10 is fixed in a frame-shaped container case 11 which is approximately U-shaped and is open on the front side of the page in FIG. Container case 11
is driven by the drive device 12 to the shaft 13 (second
(Fig. 3) in the direction of arrow A (Fig. 3) to mix the powder and granular material in the container 10. 1 in the diagram
4 is a frame, 15 is a bed, and 16 is a safety lever.

In FIG. 4, which shows the container 10, a container-shaped main body 20 has an upper input port 21 and a lower discharge port 22. A pedestal 24 is formed at the bottom of the main body 20 to surround the discharge port 22 and support the main body 20. A square vibrator 25 extending perpendicularly to the plane of the paper of FIG. 4 is welded to the lower end surface of the frame 24 over the entire depth. The side surface 26 of the square vibrator 25 approximately corresponds to the full width end surface of the container 10 , and the blind plate 2 is installed at the end opening of the square vibrator 25 so as to substantially match the full depth end surface of the container 10 .
7 is welded. A square vibrator 25 is similarly welded to the upper surface of the main body 20. Therefore, the four square vibrators 25 and the like described above are external members that determine the external dimensions of the container 10. Note that the external member is not limited to the square pipe 25, but may also be a combination of channel material, angle material, etc. Two square vibrators 28 are welded to the upper surface of the square vibrator 25.

As shown in FIG. 6, the container case 11 is formed by welding square pipes 30, and has a substantially U-shaped frame (FIG. 7) that is open on the front side in FIG. Two guides 31 are welded to both lower ends of the container case 11. The guide 31 has walls 32 in the left-right direction and walls 33 in the front-rear direction. The corner vibrator 25 of the container 10 is positioned by the wall portions 32 and 33 in both left and right and front and back directions.

A tapered surface 34 that opens upward is formed on the wall portion 32, and this tapered surface 34 functions to guide the side surface 26 of the square vibe 25. A rubber plate 35 is glued to the square pipe 30a on the back side of the container case 11.
The back side of the container 10 is placed against the rubber plate 35 to determine the longitudinal position of the container 10. There are shafts 1 on both left and right sides of the container case 11.
3 is welded to the bearing 36 through which it passes.

Left and right corner vibrators 30b of the container case 11 (Fig. 8)
A hydraulic cylinder 40 is housed therein as shown in FIG. The hydraulic cylinder 40 has a rod 41 fixed in an upwardly extended position. Bushes 42 (FIG. 1O) are provided at two locations on the left and right square vibrators 30c connected to the upper ends of the square pipes 30b so as to sandwich a hydraulic cylinder 40 therebetween. Note that a pneumatic cylinder can also be used instead of the hydraulic cylinder 40.

The hydraulic cylinder 40 is for vertically moving a press plate 43 (pressing member) shown in FIG. 1, and a rod 41 is connected to the press plate 43. The presser plate 43 has the bushing 4
2 is provided with a rod 44 which is slidably fitted into the holding plate 43. The rod 44 guides the holding plate 43 up and down in a substantially horizontal position. As shown in FIG. 11, the holding plate 43 has left and right walls 45 and front and rear walls 46 formed to position the square pipe 25 on the top surface of the container 10. The wall portions 45 and 46 are set to a height that allows the container 10 to be taken in and out from the front of the container case 11 when the hydraulic cylinder 40 is extended. The wall portion 46 is formed with a tapered surface 47 that opens downward.

Note that the holding plate 43 is not limited to the case where the walls 45, 46 and the tapered surface 47 are formed, but may be formed into a substantially flat plate shape, and at least when the hydraulic cylinder 40 is tightened, the container 10 is pressed downward by force. Any shape is fine.

In the above embodiment, the container 10 is taken in and out of the container case 11 in the following manner. First, the hydraulic cylinder 40
is extended to raise the presser plate 43 to the position indicated by reference numeral 43a in FIG. The container 10 is lifted by placing the square pipe 28 shown in FIG. 4 on the fork of a forklift, and is inserted through the front opening of the container case 11 in the direction of arrow B in FIG. 3. At this time, the container 10 is put into the container case 11 so that the corner vibrator 25 on the bottom surface of the container 10 goes over the wall 33 of the guide 31, and the back surface of the container 10 is placed against the rubber plate 35 of the container case 11. Buffers shock. When lowering the container 10 onto the guide 31, the side surface 26 of the square vibrator 25 is guided by the tapered surface 34 of the wall portion 32 and positioned laterally. Therefore, when the container 10 is lowered into the guide 31, the corner vibrator 25 on the lower surface of the container 10 is positioned by the wall portions 32, 33 in the front and rear, right and left directions.

After the container 10 is placed in the container case 11, the hydraulic cylinder 40 is shortened to press down the square pipe 25 on the upper surface of the container 10 with a presser plate 43, and the container 10 is similarly positioned back and forth and left and right.

Since the hydraulic cylinder 40 is housed within the frame, it does not protrude from the upper surface of the container case 11, and the outer shape of the container case 11 is small. Therefore, the rotation locus 50 (FIGS. 2 and 3) when the container case 11 is rotated becomes smaller.
The safety lever 16 can also be small.

(Effects of the Invention) As explained above, in the powder mixing device according to the present invention,
Since the external dimensions of the container 10 are determined by the square vibrator 25, even when a large number of containers 10 are alternately put in and taken out from the container case 11, there is no variation in the external dimensions of the container 10 unlike in the conventional case, and the container 10 made of a thin plate can be used. can be evenly pressed and fixed by the guide 31 and press plate 43 of the container case 11.

Since the wall portions 32 and 33 are formed on the guide 31, the corner vibrator 25 of the container 10 can be positioned in the front and back, left and right directions. Furthermore, since the tapered surface 34 is formed on the wall portion 32, when the container 10 is lowered onto the guide 31, the side surface 26 of the square vibrator 25
The square vibrator 25 can be fitted into the correct position in the left-right direction by being guided by the tapered surface 34.

Since the hydraulic cylinder 40 is housed inside the square vibrator 30b, the hydraulic cylinder 40 does not protrude from the upper surface of the container case 11, and the outer shape of the container case 1 can be made smaller. When the container case 11 becomes smaller, the rotation trajectory 50
It is also smaller, requiring less space to install the device.
