Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for adjusting the supply amount at each discharge port of a container such as a mixer and a hopper that contains powdery particles or a container that contains a viscous material such as miso.

[0002]

[Prior art]

 Conventionally, a rotary feeder, a table feeder, and the like have been used to adjust the discharge (supply to other devices) of the powdery or granular material at the discharge port, but the mechanism is complicated.

On the other hand, in a slide gate in which a flat opening / closing plate is reciprocally moved at an outlet, since the opening / closing plate supports the gravity of powdery or viscous particles contained in the outlet, friction during reciprocation is significant. , Adjustment work requires unnecessary driving force.

[0004]

[Problems that the device needs to solve]

 It is an object of the present invention to provide a discharge device at an adjusting port that has a simple structure for adjusting the discharging port and that reduces friction associated with the adjustment.

[0005]

[Means for solving the problem]

 In order to solve the above-mentioned problems, the structure of the present invention is provided with a passage hole at a discharge port of a container, which is supported by a rotating circular ring or a rotating ball and which makes a rotational movement, and drives the rotating plate. It consists of an outlet adjustment device that opens and closes the outlet by providing a source.

[0006]

[Function of the device]

 As described above, in the present invention, as shown in FIG. 1, the turntable 2 is supported by the rotating circular ring or the rotating ball 3 (for the specific configuration thereof, the first, second, and third embodiments are described. As shown in FIG. 1 and as shown in FIG. 1, a passage hole 21 is provided in the turntable 2. However, if the passage hole 21 matches a part or all of the discharge port 11, When the powdery or viscous material in 1 is discharged to the outside, the passage hole 21 does not coincide with the position of the discharge port 11, and a portion other than the hole of the rotary disk 2 covers the discharge port 11, The discharge of the powdery or granular material or the viscous material inside the container 1 to the outside is blocked. That is, the discharge port 11 is opened and closed by the rotational movement of the turntable 2.

Rotational movement of the turntable 2 for opening and closing the discharge port 11 depending on the position of the passage hole 21 usually employs reciprocating rotational movement in many cases, but is not necessarily limited to reciprocating movement. That is, it is sufficiently possible to control the opening / closing of the discharge port 11 by controlling the stationary position of the turntable 2 and rotating only in one direction. The most typical configuration for controlling the opening and closing by the reciprocating movement is a device that detects the rotational position of the turntable 2 by the limit switch and realizes the reciprocating rotational movement by using the reversible motor as the drive source 4. .

In the present invention, the reason why the rotating body 3 is supported by the rotating circular ring or the rotating ball 3 is that the weight of the inclusions such as powder particles or viscous bodies of the rotating disk 2 is not supported. This is to eliminate frictional resistance during the rotation and to realize smooth movement.

[0009]

First Embodiment As shown in FIG. 2, the first embodiment shows a configuration in which the rotating disk 2 is supported from below by a rotating body 3 that can rotate around three or more fixed shafts 32 from below.

The reason why the fixed shaft 32 and the rotating circular ring 3 are three or more is that the support for the rotating disk 2 becomes unstable when the number is two or less.

When the ball bearing 31 is further interposed between the rotating circular ring 3 and the fixed shaft 32, the rotating circular ring 3 rotates more smoothly.

[0012]

Second Embodiment In the second embodiment, as shown in FIG. 3, a fixed base 33 having a circular ring-shaped groove 34 is provided, and a circular ring parallel to the groove 34 is provided in the lower part of the turntable 2. A structure in which the rotating ball 3 is interposed between the circular ring-shaped grooves 34 is shown. As a result, the turntable 2 is supported by the fixed base 33 via the rotary balls 3 and can realize smooth rotational movement.

[0013]

Third Embodiment A third embodiment shows a case where the rotary disk 2 is a disk and the circumference thereof is supported by an existing ball bearing 31. In this case, the ball bearing 31 receives a pressing force from the inclusion body not at the circumferential direction but at the lower part of the groove 34. However, despite the pressing force, the original function of the ball bearing 31 is. Based on the above, the turntable 2 can smoothly rotate and move.

[0014]

[Embodiment 4] When a mixer is used as the inner package, the powder particles collide with the wall portion of the mixer based on the rotation of the inner rotary blades, and the wall portion is easily worn. . In such a case, if the turntable 2 of the present invention in the transport hole is at the same level as the inner wall of the mixer, the turntable 2 will also wear as a natural result. In the third embodiment, as shown in FIG. 5, in order to avoid such wear, the discharge port 11 itself is projected outside from the inner wall of the mixer, and the rotating body 3 is provided at the position of the discharge port 11. This makes it possible to prevent wear of the inner surface of the turntable 2.

[0015]

[Effect of device]

 In the present invention having the above-described structure, the structure is much simpler than that of the conventional supply device at the discharge port, and the movement accompanying the adjustment can be performed smoothly.

Moreover, since the movement itself is a rotary motion, the motion of a rotary drive source such as a commonly used motor can be transmitted straight, and the loss of torque and energy is extremely small.

Further, depending on the design, it is possible to use an existing ball bearing, and the design is easy.

As described above, the present invention has various advantages in adjusting the supply of the powdery or granular material or the viscous material at the discharge port, and its value is immense.
