る。The operation of the prior art will be described below. A powder / particle storage source (having a gas inlet) in which the powder is stored is connected to the powder supply port. After such preparation, the following operation is performed by operating the gas suction device. In other words, before the gas suction device is operated, the state in which the particulate discharge port is not completely closed by the action of the balance weight, that is, a standby state is provided with a predetermined gap between the powder discharge port and the particulate discharge port. When the gas suction device is operated, the inside of the storage tank has a negative pressure due to the operation of the gas suction device, so that the opening / closing valve body is sucked toward the granular material discharge port side, thereby completely closing the granular material discharge port. At this time, the powder particles adhering to the periphery of the powder discharge port and the portion of the opening / closing valve body opposed thereto are soared upward by the flow of air flowing into the storage tank through the gap therebetween, so that the opening / closing valve The body will close without biting of the granular material. After that, since the inside of the storage tank becomes further negative pressure, the granular material flows into the storage tank together with the gas from the granular material supply port,
The gas exits through the gas suction port, and the granular material is stored in the storage tank. Then, when a predetermined amount of the granular material accumulates, the gas suction device is stopped. As a result, the self-weight of the stored granules overcomes the force of the balance weight due to the fact that the pressure in the storage tank is no longer negative, so that the on-off valve body opens, and the granules are discharged from the granule discharge port. Is more exhausted. When the granular material is completely discharged from the storage tank, the opening / closing valve body returns to the above-described state in which the granular material discharge port is substantially closed (the state in which the granular material discharge port is not completely closed) by the function of the balance weight.

った。Disadvantages of the prior art The conventional storage apparatus has the following disadvantages. That is, the gas suction device is stopped when a predetermined amount of the granular material accumulates, and then completely stopped after the gas suction device operates for a predetermined time by inertia, and then the air naturally flows into the storage tank and the storage tank is stopped. Wait for the inside to return to atmospheric pressure naturally, and as a result, open and close the valve body automatically by the own weight of the stored granules, and discharge the granules from the granule discharge port. For this reason, the time from when the gas suction device is stopped to when the on-off valve body is completely opened and the powder and granules are discharged becomes considerably long, and the operating efficiency is poor.

In a state where the balance is balanced, that is, in a state in which a predetermined gap 43 is formed between the on-off valve body 37 and the peripheral edge of the granular material discharge port 26, this state is maintained.
3 is provided across the swing arm 31 and the tank body 3 (specifically, the bracket 29). The retainer 53 includes:
Although the swing arm 31 resists swinging in the direction in which the on-off valve body 37 is closed, the swing arm 31 is allowed to swing in the direction in which the on-off valve body 37 is opened. Here, "resisting the swing arm 31 from swinging in the direction to close the opening and closing valve body 37" means that the swing arm 31 is completely prevented from swinging in the direction to close the opening and closing valve body 37. However, if the force acting on the on-off valve body 37 in the direction to close the on-off valve body 37 is within a set value, it means that the force is overcome and the on-off valve body 37 is not completely closed. Further, as described above, the opening / closing valve body 37 itself is slightly moved up and down even if the swing arm 31 does not swing in the direction to close the opening / closing valve body 37. Even when the on-off valve body 37 is positioned at the uppermost position with respect to the swing arm 31 in a state in which the balance with the body 37 is balanced, the on-off valve body 37 does not abut on the peripheral edge of the granular material discharge port 26.

定間隙43をあけた状態に戻る。Next, the operation of the first embodiment of the present invention will be described. The powder supply pipe 16 is connected to a powder storage source (not shown) having a gas inlet, in which the powder is stored. After such preparation, if the gas suction device 61 is operated, the following operation is performed. That is,
Before the gas suction device 61 operates, the balance weight 4
The opening / closing valve body 37 in a state in which the granular material discharge port 26 is not completely closed by the action of 0, that is, a state in which a predetermined gap 43 is provided between the open / close valve body 37 and the granular material discharge port 26, When the gas suction device 61 is operated, the inside of the storage tank 1 becomes negative pressure.
As shown by the arrow L in FIG. 2 with the swing of the drum 31, it moves upward to completely close the granular material discharge port 26. At this time, the powder / particle discharge port 26 is directed right below, and the entire periphery of the powder / particle discharge port 26 is almost the same distance as the gas suction port 22. The powder particles adhering to the valve element 37 are soared upward at the same or almost the same speed by the air flow of the same or almost the same speed flowing into the storage tank 1 through the gap 43 between them. The on-off valve body 37 is completely closed without biting of the granular material. With the operation, the rod 56 climbs the cam surface 54a of the cam plate 54 against the force of the spring 57. Thereafter, since the inside of the storage tank 1 further becomes a negative pressure, the powder and the granular material flow into the storage tank 1 together with the gas from the powder and granular material supply port 18, the gas exits from the gas suction port 22, and the powder and the granular material It is stored in the storage tank 1. Then, when a predetermined amount of the granular material accumulates, the gas suction device 61 is stopped. When the gas suction device 61 stops, the discharge port opening / closing valve 6 operates in conjunction therewith.
5 is closed, and the gas in the storage tank 1 is prevented from being sucked from the storage tank 1 by the inertial operation of the gas suction device 61. Thereafter, the predetermined gap 43 is forcibly formed between the opening / closing valve body 37 and the periphery of the granular material discharge port 26 by the action of the retainer 53 (by the rod 56 descending the cam surface 54a according to the force of the spring 57). Therefore, the atmosphere is introduced into the storage tank 1, and the inside of the storage tank 1 is returned to the atmospheric pressure in a short time. Along with this, the own weight of the stored granules overcomes the force of the balance weight 40, the opening / closing valve body 37 opens to the position indicated by the dashed line in FIG.
Exhausted from 6. When the granular material is completely discharged from the storage tank 1, the opening / closing valve body 37 returns to a state in which the granular material discharge port 26 is substantially closed (a state in which the granular material discharge port 26 is not completely closed) by the action of the balance weight 40. . In this state, even if the gas suction device 61 does not operate and the force for pushing the open / close valve body 37 upward acts on the open / close valve body 37, if the force is within the set value, the spring 57 Overcomes the force and does not completely close the on-off valve body 37. When the above-mentioned force (the force for pushing the opening / closing valve body 37 upward on the opening / closing valve body 37) is no longer applied, the opening / closing valve body 37 is moved between the opening / closing valve body 37 and the periphery of the granular material discharge port 26 by the action of the cam surface 54a. The state returns to the state where the predetermined gap 43 is left.

In addition, when the discharge port opening / closing valve is closed, the flow of the gas flowing backward in the storage tank is instantaneously generated, so that the powder flowing from the porous plate can be removed by the gas flowing backward. According to the invention of claim 2, when the gas suction device stops, the suction port opening / closing valve closes in conjunction therewith, thereby preventing the gas in the storage tank from being sucked from the storage tank by the inertial operation of the gas suction device. Therefore, the inside of the storage tank can be returned to the atmospheric pressure in a short time, and as a result, the time from when the gas suction device is stopped to when the on-off valve is completely opened and the powder is discharged is shortened. As a result, the operation efficiency can be increased. According to the third aspect of the present invention, the air inlet is opened in conjunction with the stop of the gas suction device, and a large amount of air is introduced from the air inlet. Since the gas inside is prevented from being sucked and the air flows into the storage tank, the inside of the storage tank can be returned to the atmospheric pressure in a short time, and as a result, after stopping the gas suction device, The operation time can be improved by shortening the time from when the on-off valve body is completely opened to when the granular material is discharged.
