When the valve rotation shaft 141B is rotated about 90 degrees from the state where the flow path 120A is blocked, the blocking of the material flow path 120A by the disc body 141A is released. In the following, as shown in FIG. 1, the state in which the disc body 141A blocks the material flow path 120A is the non-discharge state of the material discharge portion 120 and the disc body 141A as shown in FIG.

Further, as shown in FIG. 2, when the valve rotation shaft 152 is rotated so that the surface direction of the disc body 151 and the axial direction of the air flow path 131B substantially coincide with each other, for example, the air is caused by the disc body 151. When the valve rotation shaft 152 is rotated about 90 degrees from the state where the flow path 131B is blocked, the block of the air flow path 131B by the disc body 151 is released.

The state in which the air flow path 131B is released will be referred to as the supply state of the air supply unit 130 as appropriate. Here, a configuration in which the state in which the valve rotation shaft 152 is rotated about 90 degrees from the non-supply state of the air supply unit 130 is set to the supply state will be described, but not limited to this, the air flow path 131B by the disc body 151 is described. As long as the shut-off state is released, another configuration may be used as appropriate, such as a configuration in which the valve rotation shaft 152 is rotated about 45 degrees.

  The switching transmission means 160 includes, for example, a shaft 161 provided so that the axial direction substantially coincides with the valve rotation shaft 141B on the left side of the valve rotation shaft 141B, and a transmission umbrella provided on the left end of the shaft 161 on the paper surface.

  The gears 141C, 142B, 153, 162, 163, 165, and 166 are configured such that when the material discharge unit 120 is switched to the non-discharge state, the air supply unit 130 is switched to the non-supply state. The number of teeth, the meshing position, and the like are set so that the air supply unit 130 is switched to the supply state when the discharge state is switched.

[Container behavior]
Next, the operation of the container will be described. Here, when the operation unit 142A of the shut-off control unit 142 is rotated by a predetermined angle, for example, about 90 degrees, a configuration in which the disk bodies 141A, 151A rotate by about 90 degrees will be described as an example. Is not limited to about 90 degrees, and may be other angles as appropriate.

  First, the container body 110 in which the powder material F is stored in the material storage space 110A with the material discharge unit 120 in a non-discharge state and the air supply unit 130 in a non-supply state is stored in a storage tank 800 using a forklift (not shown), for example. Move upwards. Next, the container main body 110 is moved downward, and the material discharge part 120 is fitted to the tank connection part 810 as shown in FIG. Thereafter, when the operating portion 142A is rotated by about 90 degrees in the direction of the arrow R10 by operating the handle 142A1, the valve rotation shaft 141B and the disc body 141A are rotated by about 90 degrees in the direction of the arrow R11. Thereby, as shown in FIG. 2, the material discharge unit 120 is switched to the discharge state, and the powder material F passes through the material flow path 120 </ b> A of the material discharge unit 120 and is discharged into the storage tank 800.

  Further, when the operation unit 142A is rotated by about 90 degrees in the arrow R10 direction, the shaft 161 is rotated in the arrow R12 direction. When the shaft 161 is rotated, the shaft 164 is rotated in the direction of the arrow R13. As the shaft 164 is rotated, the valve rotating shaft 152 and the disc body 151 are rotated by about 90 degrees in the direction of the arrow R14. As a result, as shown in FIG. 2, the air supply unit 130 switches to the supply state, and the air existing outside the container body 110 passes through the opening 132B, the air introduction channel 132A, and the air channel 131B. It flows into the material storage space 110A.

  Thereafter, when the material discharge unit 120 is switched to the non-discharge state and the air supply unit 130 is switched to the non-supply state, the operation unit 142A is rotated by, for example, about 90 degrees in the direction opposite to the arrow R10 direction. Accordingly, the disk bodies 141A and 151A are rotated by about 90 degrees in the direction opposite to the above-described direction, and the material discharge unit 120 is switched to the discharge state and the air supply unit 130 is switched to the supply state.

[Operational effects of the first embodiment]
As described above, in the first embodiment, the following operational effects can be achieved.

(1) In the container 100, the discharge state switching means 140 for switching the material discharge portion 120 between the discharge state of the powder material F to the storage tank 800 and the non-discharge state, and the discharge state switching means 140 in conjunction with the discharge state switching means 140 A butterfly valve 150 that switches the air supply unit 130 to an air supply state when the material discharge unit 120 is discharged, and switches the air supply unit 130 to a non-air supply state when the material discharge unit 120 is not discharged. Yes. For this reason, when the discharge state switching unit 140 is operated so as to switch the material discharge unit 120 to the discharge state, the powder material F is discharged from the material storage space 110A and linked to the operation of the discharge state switching unit 140. Then, the butterfly valve 150 operates, the air supply unit 130 switches to the supply state, and air is supplied to the material storage space 110A. Therefore, the powder material F can be discharged and air can be supplied to the material storage space 110A simply by operating the discharge state switching means 140, and the material storage space 110A can be reliably prevented from being evacuated. For example, even if the container 100 is disposed at a high place and the air supply unit 130 is located at a high place, the air can be supplied to the material storage space 110A simply by operating the discharge state switching means 140. Supply work can be facilitated. Furthermore, since the air supply unit 130 can be switched to the non-supply state simply by switching the material discharge unit 120 to the non-discharge state by operating the discharge state switching means 140, for example, it is normally performed at the end of the discharge operation of the powder material F. The air supply unit 130 can be reliably brought into the non-supply state only by switching the material discharge unit 120 to the non-discharge state. Therefore, the powder material F can be easily discharged to the outside.

(2) The switch transmission means 160 that transmits to the butterfly valve 150 that the material discharge section 120 has been switched between the discharge state and the non-discharge state is provided with generally inexpensive shafts 161 and 164 and the gears 162. , 163, 165, 166. For this reason, the structure of the switching transmission means 160 can be simplified and the cost can be reduced.

(3) The discharge state switching means 140 is provided with a butterfly valve 141 that switches the material discharge unit 120 to the discharge state by releasing the blocking of the material flow path 120A, for example. For this reason, the block of the material flow path 120A can be released simply by rotating the butterfly valve 141, and the configuration of the discharge state switching means 140 can be simplified. In addition, since the inexpensive butterfly valve 141 is generally used, the cost of the discharge state switching means 140 can be reduced.

(4) The butterfly valve 150 is configured to switch the air supply unit 130 to the supply state, for example, by releasing the block of the air flow path 131B. Therefore, the air flow path 131B can be disconnected only by rotating the butterfly valve 150, and the configuration for switching the air supply unit 130 between the supply state and the non-supply state can be simplified. In addition, since the inexpensive butterfly valve 150 is generally used, it is possible to reduce the cost of the configuration in which the air supply unit 130 is switched between the supply state and the non-supply state.

(5) The air supply part 130 is provided with a second cylindrical part 132 having an opening part 132B opened in the horizontal direction of the first cylindrical part 131. For this reason, it is possible to prevent entry of air, for example, dust, which falls from above the container body 110 into the air introduction channel 132A. Accordingly, it is possible to prevent dust and the like from entering the powder material F stored in the material storage space 110A communicated via the air introduction channel 132A and the air channel 131B. Further, since only the opening direction of the opening 132B is adjusted, it is possible to prevent dust and the like from entering the powder material F without significantly increasing the cost.

(6) The second cylindrical portion 132 is provided so as to protrude obliquely downward from the side surface of the first cylindrical portion 131. Therefore, in addition to dust falling from the upper side of the container main body 110, intrusion of dust falling from an oblique upper side of the container main body 110 into the air introduction flow path 132A is performed on the side surface of the second cylindrical portion 132. Can be prevented by a member constituting the. Accordingly, it is possible to further prevent dust and the like from entering the powder material F stored in the material storage space 110A.

(7) The air supply unit 130 is provided above the main body top plate 112 of the container main body 110. For this reason, even if the powder material F is stored so as to fill the material storage space 110A, the powder material F is not discharged from the air supply unit 130 when the air supply unit 130 is switched to the supply state. . Therefore, a large amount of the powder material F can be stored in the material storage space 110A as compared with the configuration in which the air supply unit 130 is provided in the main body upper portion 111 and the lower main body 113 of the container main body 110.

  Thus, the closing body 551 is guided upward by the control shaft 552 and the coil spring 554, and the upper end sides of the closing body upper portion 551A and the closing body lower portion 551B protrude from the upper surface of the closing portion 530A of the air supply unit 530. In addition, the closure body engagement hole 530A1 is closed by engaging the closure body engagement hole 530A1 while maintaining airtightness with the closure body engagement hole 530A1 on the circumferential surface of the closure body lower portion 551B. As will be described in detail later, the closing body 551 is guided downward by the suction force, and the closing body engaging hole 530A1 is opened by releasing the engagement with the closing body engaging hole 530A1. Hereinafter, as shown in FIG. 7, the state where the closing body 551 closes the closing body engaging hole 530A1 will be referred to as a non-supply state of the air supply unit 530 as appropriate. In addition, as shown in FIG. 8, the state in which the closing body 551 opens the closing body engaging hole 530A1 will be referred to as a supply state of the air supply unit 530 as appropriate.

  Further, a portion of the valve rotating shaft 141B exposed to the outside of the material discharge unit 120, members other than the operation unit 142A of the shut-off control unit 142, and the like are protected from foreign matters by a cover (not shown). Further, support legs 115 are provided in the vicinity of the coupling portion between the main body upper portion 111 and the main body lower portion 113 of the container main body 110.

[Container behavior]
Next, the operation of the container will be described. Here, as in the first embodiment, when the operation unit 142A is rotated by a predetermined angle, for example, 90 degrees, the configuration in which the disk body 141A rotates by about 90 degrees will be described as an example. Not limited to.

  First, the container main body 110 storing the powder material F is moved by, for example, a forklift (not shown) with the material discharge unit 120 in a non-discharge state and the air supply unit 530 in a non-supply state, as shown in FIG. The material discharge part 120 is fitted to the tank connecting part 810. Next, when the operating portion 142A is rotated by about 90 degrees in the direction of the arrow R50 by operating the handle 142A1, the valve rotation shaft 141B and the disc body 141A are rotated by about 90 degrees in the direction of the arrow R51. Thereby, as shown in FIG. 8, the material discharge unit 120 is switched to the discharge state, and the powder material F passes through the material flow path 120 </ b> A of the material discharge unit 120 and is discharged into the storage tank 800.

  When the powder material F is discharged from the material storage space 110A, the pressure in the material storage space 110A and the air flow path 530B communicated with the material storage space 110A is reduced. The closing body 551 is urged downward by a downward suction force generated by a pressure difference between the air introduction space 531 and the air flow path 530B. Thereafter, when the suction force becomes larger than the upward biasing force by the coil spring 554, the closing body 551 moves to the inside of the air flow path 530B. As a result, as shown in FIG. 8, the engagement between the closing body 551 and the closing body engaging hole 530A1 is released, the air supply unit 530 is switched to the supply state, and the air existing outside the container body 110 is It passes through the air introduction gap 532, the air introduction space 531, the closing body engaging hole 530A1, the air flow path 530B, and the communication hole 553B and flows into the material storage space 110A.

  Thereafter, when the pressure of the air flow path 530B increases due to the inflow of air into the material storage space 110A and the downward suction force becomes smaller than the upward biasing force by the coil spring 554, the closing body 551 moves upward. Thus, the air supply unit 530 is switched to the non-supply state by engaging with the closing body engagement hole 530A1. Further, when the operation unit 142A is rotated by about 90 degrees in the direction opposite to the arrow R50 direction, the disc body 141A is rotated by about 90 degrees in the direction opposite to the above-described direction, and the material discharge unit 120 is brought into a non-discharge state. Switch.

[Effects of Fifth Embodiment]
As described above, in the fifth embodiment, in addition to the same functions and effects as the above-described (1), (3), and (7), the following functions and effects can be achieved.

(12) The supply state switching means 550 is configured to switch the air supply unit 130 from the non-supply state to the supply state by a suction force acting from the outside to the inside of the material storage space 110A. Therefore, it is not necessary to provide a switching transmission means for transmitting the operation of the discharge state switching means 140 to the supply state switching means 550, and the configuration of the container 500 can be simplified.

(13) Suction force generated by a decrease in pressure in the material storage space 110A and the air flow path 530B when the powder material F is discharged from the material storage space 110A as a suction force acting from the outside to the inside of the material storage space 110A Is used. For this reason, since the special structure which generate | occur | produces the attraction | suction force mentioned above is not provided, the structure of the container 500 can be simplified more.

(14) For example, the air supply unit 530 is switched to the supply state by opening the closing body engaging hole 530A1 in the closing body 551 of the supply state switching means 550. For this reason, the air supply unit 530 can be switched to the supply state with a simple configuration by simply opening the closing body engagement hole 530A1, and the configuration of the supply state switching means 550 can be simplified.

(15) The supply state switching means 550 is provided with a coil spring 554 that biases the closing body 551 in a direction to close the closing body engaging hole 530A1. Therefore, when the suction force is not acting, the closing body engaging hole 530A1 can be reliably closed by moving the closing body 551 upward by the coil spring 554. Accordingly, it is possible to further prevent dust and the like from entering the powder material F stored in the material storage space 110A.

(16) The supply state switching means 550 includes a closing body 551, a control shaft 552, a closing control member 553, and a coil spring 554 that are generally inexpensive or easy to form. For this reason, the structure of the supply state switching means 550 can be simplified and the cost can be reduced.

(17) The container 500 is provided with a supply unit protection member 570 disposed so as to cover the air supply unit 530. For this reason, it is possible to prevent intrusion of dust and the like into the air flow path 530B from the upper side, the diagonally upper side, the diagonally lower side, the side of the container main body 110, and further from the back side and the front side in the paper surface direction. Accordingly, it is possible to further prevent dust and the like from entering the powder material F stored in the material storage space 110A. In addition, the air supply unit 530 can be protected from collisions with foreign matters and the air supply unit 530 can be prevented from being damaged.

[Modification of Embodiment]
In addition, this invention is not limited to embodiment mentioned above, The deformation | transformation shown below is included in the range which can achieve the objective of this invention.

  That is, in the fifth embodiment, the suction force acting from the outside to the inside of the material storage space 110A is caused by a decrease in the pressure of the material storage space 110A when the powder material F is discharged from the material storage space 110A. Although the configuration using the suction force has been illustrated, the present invention is not limited thereto, and for example, the following configuration may be used. That is, when the container main body 110 or the air supply unit 530 detects that the material discharge unit 120 has been switched to the discharge state, the suction force generation means generates a suction force that acts from the outside to the inside of the material storage space 110A. It is good also as a structure provided.

  In the third embodiment, the material discharge unit 120 is fitted into the tank connection unit 810, and the valve pinion 342 of the container 300 is rotated by the rack 920 of the storage tank 900, so that the material discharge unit 120 is discharged. Although the configuration for switching is illustrated, the configuration is not limited thereto, and other configurations may be appropriately used as long as the material discharging unit 120 is switched to the discharging state when the material discharging unit 120 is fitted to the tank connecting unit 810. That is, for example, a fitting detection unit that detects that the material discharge unit 120 is fitted to the tank connection unit 810, and that the material discharge unit 120 is fitted to the tank connection unit 810 by the fitting detection unit. A first switching unit that switches the material discharge unit 120 to a discharge state when detected, a second switching unit that switches the air supply unit 130 to a supply state in conjunction with the first switching unit, and the like. It is good also as a structure. In addition, as a fitting detection means, it is good also as any structure which can detect that the material discharge part 120 was switched to the discharge state, such as a contact type and a non-contact type. The first switching unit and the second switching unit can be exemplified by the configurations exemplified in the respective embodiments, but are not limited thereto.

  Moreover, in each embodiment, although illustrated about the structure which used the butterfly valve 141 as a stored thing cutoff valve and the butterfly valve 150 as an air cutoff valve, it is not restricted to this, Other valve bodies, such as a gate valve and an electromagnetic valve, Any member that can block the material flow path 120A and the air flow path 131B may be applied.

  In the first, second, and third embodiments, the configuration in which the second cylindrical portion 132 is coupled to the first cylindrical portion 131 of the air supply unit 130 has been illustrated. A configuration in which the cylindrical portion 132 is not provided may be employed. With such a configuration, the configuration of the air supply unit 130 can be simplified.

  Further, in the configuration in which the second cylindrical portion 132 is not provided in the air supply unit 130, a configuration in which the closing portion 131A is not provided in the first cylindrical portion 131 may be employed. With such a configuration, the configuration of the air supply unit 130 can be further simplified.

  In the fifth embodiment, the configuration in which the supply unit protection member 570 disposed so as to cover the air supply unit 530 is provided in the container 500 is illustrated, but the configuration in which the supply unit protection member is not provided may be employed. . With such a configuration, the configuration of the container 500 can be simplified and reduced in weight. Further, when the supply portion protection member 570 is not provided, even if dust or the like has fallen on the air supply portion 530, the closure body upper portion 551A of the closure body 551 is formed in a substantially conical shape. Falls down along the side surface of the upper portion 551A of the closing body. For this reason, since dust or the like does not accumulate in the portion of the closing body 551 that protrudes from the upper surface of the closing portion 530A, the material discharging portion 120 switches to the discharging state, and the closing body 551 moves into the air flow path 530B. Even if it does, dust etc. do not penetrate | invade into the air flow path 530B. Accordingly, dust and the like can be prevented from entering the powder material F stored in the material storage space 110A with a simple configuration in which the closing body upper portion 551A of the closing body 551 is formed in a substantially conical shape.

  In the first, second, fourth, and fifth embodiments, the structure in which the handle 142A1 is provided in the discharge state switching unit 140 has been illustrated. However, the handle 142A1 is not provided, for example, by the control of the line control unit of an automated line. It is good also as a structure etc. which rotate the operation part 142A. With this configuration, the air supply units 130, 430, and 530 can be switched between the supply state and the non-supply state only by controlling the operation unit 142A to be rotated by the line control unit. Therefore, the powder material F can be easily discharged to the outside without any human work.

  Moreover, it is good also as a structure which combined the structure of 1st Embodiment arbitrarily.

  Furthermore, although the present invention has been illustrated with respect to the configuration applied to the containers 100, 200, 300, 400, 500 for storing the powder material F, which is the material of the plasma display panel, the present invention is not limited to this. The present invention can also be applied to containers that store items other than the body material F.

  Moreover, as a storage thing stored in the storage part of the container to which this invention is applied, not only a powdery storage thing but what kind of storage goods conveyed by containers, such as a liquid or a granular storage thing, is applicable.

[Effects of Embodiment]
As described above, in the above-described embodiment, the container 100 is provided with the discharge state switching means 140 for switching the material discharge unit 120 between the discharge state of the powder material F to the storage tank 800 and the non-discharge state. In conjunction with the state switching means 140, the butterfly switches the air supply unit 130 to the air supply state when the material discharge unit 120 is discharged, and switches the air supply unit 130 to the air non-supply state when the material discharge unit 120 is not discharged. A valve 150 and the like are provided. Therefore, when the discharge state switching unit 140 is operated so as to switch the material discharge unit 120 to the discharge state, the powder material F is discharged from the material storage space 110A and air is supplied to the material storage space 110A. . Therefore, the powder material F can be discharged and air can be supplied to the material storage space 110A simply by operating the discharge state switching means 140, and the material storage space 110A can be reliably prevented from being evacuated. For example, even if the container 100 is disposed at a high place and the air supply unit 130 is located at a high place, the air can be supplied to the material storage space 110A simply by operating the discharge state switching means 140. Supply work can be facilitated. Furthermore, since the air supply unit 130 can be switched to the non-supply state simply by switching the material discharge unit 120 to the non-discharge state by operating the discharge state switching means 140, for example, it is normally performed at the end of the discharge operation of the powder material F. The air supply unit 130 can be reliably brought into the non-supply state only by switching the material discharge unit 120 to the non-discharge state. Therefore, the powder material F can be easily discharged to the outside.
