４の酸化を早める空気の進入を防止できる。 Conventionally, as shown in FIG. 1, an annular dispensing opening A centered on a centerline B is made by inserting a conical cone 2 into a lower large-diameter opening of a hopper 1. The lower part of the cone 2 is horizontally projected and serves as a table 3. For this reason, the powder 4 stored in the hopper 1 flows out from the outlet A onto the table 3 and can stay on the table 3 while maintaining the angle of repose. A gate 5 is supported around the dispensing port A by a cylinder device 6 so as to be vertically movable. When this gate 5 is lowered by the cylinder device 6, the dispensing port A
is closed to prevent foreign matter, moisture, and air that accelerates the oxidation of the powder 4 from entering through the outlet A.
テーブル３上へ停留した粉粒体４を払い出す従
来例として次に説明する装置が提案されている。 The following device has been proposed as a conventional example for dispensing the powder or granular material 4 that has remained on the table 3.

生じる。 That is, as shown in FIG. 1, a plurality of scrapers 9 are fixed to a scraper ring 8 which is rotated about a center line B by a motor 7 in such a manner that they protrude above the table 3. For this purpose, the powder 4 on the table 3 is scraped downward from the outer periphery of the table 3 by the scraper 9 which rotates together with the scraper ring 8. Scraped-off powder 4
At the receiving position, there is a rotating table 11 that is driven to rotate around the center line B by a motor 10, and as the rotating table 11 rotates, the powder and granular material 4 received on the rotating table 11 is lifted from the floor. The powder 4 is transported to the fixed scraper 12 that is fixedly supported, and finally hits the fixed scraper 12 and is transferred to the conveyor 1.
3 Scraped upwards. Thereafter, it is transported by the conveyor 13 to the destination direction. In such a dispensing device, the opening width of the dispensing port A is widened and the scraper 9 is
As shown in Figure 2, when it is pushed deeply into the dispensing port A,
Although the scraping efficiency of the scraper 9, that is, the dispensing performance is improved regardless of the difficulty in fluidity of the powder, the dispensing port A cannot be closed because it interferes with the scraper 9 and the gate 5 cannot be lowered. It creates a defect that disappears.
本発明の目的は、環状形の払出口からの払出性

ものである。 The gist of the present invention is that, as a basic configuration, an annular dispensing port, a gate for closing the dispensing port, an annular table for receiving and retaining the effluent from the dispensing port, and the effluent remaining on the table. In an apparatus comprising a scraper for scraping off the scraper, and a scraper ring for supporting the scraper and rotating around the table, the scraper is supported by being horizontally rotatably attached to the scraper ring,
The present invention is characterized in that means is provided between the scraper and the scraper ring for urging the scraper in a direction away from the outlet, and a drive device is provided for rotating the scraper ring in forward and reverse directions.
以下、本発明の一実施例を第３図、第４図に基
づいて説明する。 Hereinafter, one embodiment of the present invention will be described based on FIGS. 3 and 4.

モータ７により旋回駆動自在である。 As shown in FIG. 4, the annular dispensing opening A centered on the centerline B is created by inserting a conical cone 2 into the lower large-diameter opening of the hopper 1. The lower part of the cone 2 is horizontally protruded and serves as a table 3 for retaining the granular material 4 in the hopper 1. A gate 5 is supported around the dispensing port A by a cylinder device 6 so as to be vertically movable. A scraper ring 8 disposed around the table 3 can be driven to rotate around a center line B by a motor 7.
スクレーパリング８には、垂直な回転軸１４に
よりスクレーパ９が水平回転自在に取り付く。 A scraper 9 is attached to the scraper ring 8 so as to be horizontally rotatable via a vertical rotation shaft 14.

されて配置されている。 A spring 15 and a stopper 16 are installed between the scraper ring 8 and the scraper 9, as shown in FIG. One end of the spring 15 is the scraper 9
The other end is connected to the scraper ring 8, and a tensile force is applied to the spring 15 in advance. One end of the stopper 16 is fixed to the scraper ring 8, and the other end is fixed to the rotation area of the scraper 9 on the table 3.
It is arranged so as to protrude to a position where it can be controlled within a range that does not fall off the top and does not overlap vertically with the gate 5.

でコンベア１３を有する。 An annular rotating table 11 centered on a center line B is installed below the table 3 and can be rotated freely by a motor 10. A fixed scraper 12 projected onto the rotating table 11 is fixedly supported from the floor. A conveyor 13 is provided on the floor and is arranged to pass below a fixed scraper 12.

閉じられている。 When the dispensing operation is paused, the scraper 9 is drawn toward the scraper ring 8 by the spring 15, so the scraper 9 automatically rotates around the rotating shaft 14 until it hits the stopper 16 and closes the dispensing opening. Evacuated from side A. Then, the gate 5 is lowered by the cylinder device 6, and the dispensing port A is closed.

輸送される。 When performing the next dispensing operation, the gate 5 is pulled up by the cylinder device 6 to open the dispensing port A. When the dispensing port A is opened, the powder 4 in the hopper 1 falls by gravity from the dispensing port A and flows out onto the table 3.
It stays on this table 3 while maintaining the angle of repose. Thereafter, the motor 7 rotates the scraper ring 8 in the direction of the arrow X in FIG. 3, and the motor 10 rotates the turning table 11 in the direction of the arrow Y. In this way, the scraper 9 is stopped by the stopper 16 at a position where it does not come off the table 3 as shown by the two-dot chain line in FIG. The powder or granular material 4 that has been pressed is scraped off onto the rotating table 11. This scraper 9 moves toward the rotating shaft 14 toward the dispensing port A against the spring 15 due to the reaction force when it comes into contact with the powder 4.
Rotate around. Therefore, the scraper 9 is automatically moved closer to the outlet A than the gate 5 as shown in FIG.
The scraping efficiency, that is, the dispensing efficiency is improved by entering the side. Powder 4 dropped onto the turning table 11
As the turning table 11 rotates,
The fixed scraper 12 scrapes the powder onto a conveyor 13, and the conveyor 13 transports the powder and granular material 4 toward the destination.

確実にする。その後に、ゲート５をシリンダ装置
６で下げて払出口Ａを閉め、次いでモータ７を止
める。 Next, when the dispensing operation is to be stopped again, the motor 7 is stopped. Next, the motor 7 is reversely rotated to rotate the scraper ring 8 in the opposite direction of the arrow X. In this way, the powder 4 on the table 3 is placed on the back side of the scraper 9 (the side facing in the anti-X direction).
, and a force is generated that pushes the scraper 9 in the direction away from the dispensing port A. Therefore, the scraper 9 can be automatically retracted to a position where it does not vertically overlap the gate 5 without relying on the large tensile force of the spring 15. In this case, the spring 15 ensures the retraction of the scraper 9. Thereafter, the gate 5 is lowered by the cylinder device 6 to close the dispensing port A, and then the motor 7 is stopped.
以上の如く、本発明は、環状形の払出口の開閉

できるものである。 As described above, the present invention is capable of rotationally displacing the scraper between the position where it vertically overlaps with the opening/closing gate of the annular dispensing port and the position where it does not overlap, without impairing the opening/closing function of the dispensing port. This allows the payout efficiency to be improved. Further, since the scraper can be moved in and out simply by controlling the rotation of the ring to which the scraper is attached, the work of moving the scraper when opening and closing the gate can be extremely easily performed.
