供給方法、装置の実現には適用し難いことが判明した。This conventional powder container stores powder and granules in a deformable bag (usually abbreviated as flexible container) that has a powder supply port at the top and a powder discharge port at the bottom. A silo, a collapsible support, an elevating frame that is detachable from the support and movable up and down along the support, supporting the silo in a suspended state, and a pantograph mechanism that causes the elevating frame to move up and down. When supplying powder and granules, the lower part of the silo is kept along a separately provided bottom plate without completely extending the silo, and in this state, the powder and granules are supplied from the supply port. After storing the desired amount of powder and granules, the container is transported to the destination, and when discharging the powder, the elevating frame is further raised using the pantograph mechanism, the silo is completely lifted, and the lower part of the silo is lifted. After that, the discharge port is opened, and due to the presence of this angle of repose, the powder and granules in the silo are discharged properly and completely.After discharge, the silo and pantograph mechanism , and the frame is folded to reduce the occupied space, and the container is sent back to the point where the powder and granular material is received into the silo. However, in this conventional method and device for transporting and supplying powder and granules, the container itself has a built-in lifting mechanism for raising and lowering the silo, which inevitably increases the size and weight of the entire container. This problem becomes more pronounced as the capacity of the silos used increases, and when such containers are loaded onto trucks or other vehicles and transported to their destination, the Road Traffic Act, etc. It has been found that it is difficult to apply this method to the realization of a method and apparatus for transporting and supplying powder and granular material with as large a granular material storage capacity as possible under these restrictions.

ないものであることが判明した。In addition, in this conventional method and device for transporting and supplying powder and granular materials, the silo is suspended from the hanging frame at its upper part, so the load of the entire silo is locally applied to that part. As a result, the silo suffered severe wear and tear, and it was found that this method was not suitable for use as a large-sized powder transport/supply method or device.

nt, means a pellet supply line for shipping at a synthetic resin pellet manufacturing factory that pelletizes the pellets. Here, the powder supply port 44 of each silo 3 is opened, and powder and granule are supplied from the powder supply source into each silo 3 - simultaneously or sequentially. It is supplied through the port 44 until a predetermined amount is reached. At this time, the lower conical part 43 of the silo 3 is folded as shown in FIG.
In addition, the support 2
The support body 24 of is held in an upright state by a support arm 27, and the silo 3 is supported by a bracket 48, a guide roll 4
It is supported by the support body 24 via 9. When the silo 3 is filled with powder and granules, the powder supply port 44 is closed and the silo 3 is ready to be transported to the destination.

されながら案内される。One way is as follows. That is, first,
The powder discharge port 45 of the silo 3 is opened, and the powder continues to be delivered to the powder receiving location through the powder discharge pipe 46 according to the gravity of the powder, and then at an appropriate time. , connect the pressurized fluid supply pipe 47 to a pressurized fluid source installed in the factory where the powder or granular material is received, and start supplying pressurized fluid from the pressurized fluid supply pipe 47 into the size 03. , the silo 3 is extended upward, and the lower conical part 43 of the silo 3 is
(see Figure 6), thereby giving the silo 3 the angle of repose necessary for discharging the powder and granules, allowing the powder and granules to be substantially completely discharged from the silo 3, and discharging the powder from the silo 3. This completes the supply of granules to the receiving location. In addition, at this time, the silo 3 includes the bracket 48 and the guide roller 4.
9, the support body 2 is guided while being supported along the plate surface of the support body 24.

のである。なお、このときのサイロ３と支持本体２４と
の関係は、上記の場合と同じである。Another method is as follows. That is, first, the powder discharge port 45 is opened and the discharge valve (not shown) of the powder discharge pipe 46 is closed, and the pressurized fluid is supplied in the same manner as in the above case. The powder is fed into the silo 3 from the pipe 47, and the lower conical part of the silo 3 is returned to its original conical shape (see Fig. 6), thereby forming the angle of repose necessary for discharging the powder and granules. The discharge valve of the powder discharge pipe 46, which has been tightened, is released to begin supplying the powder to the powder receiving location, and the supply is completed. Note that the relationship between the silo 3 and the support body 24 at this time is the same as in the above case.

なお、前者の粉粒体排出操作は、ある程度粉粒体が排出
されてから、すなわち、サイロ３の重量がある程度軽減
されてから、加圧流体をサイロ３中に供給すればよいの
で、サイロ３の下部コニカル部４３を元のコニカル形状
に戻すための供給すべき加圧流体の圧力が、後者の粉粒
体排出操作よりも低くて済むという利点がある。In addition, in the former powder discharge operation, pressurized fluid can be supplied into the silo 3 after the powder has been discharged to a certain extent, that is, after the weight of the silo 3 has been reduced to a certain extent. There is an advantage that the pressure of the pressurized fluid to be supplied to return the lower conical portion 43 to its original conical shape can be lower than that in the latter powder discharge operation.

さて、このようにして、粉粒体の排出が終了したサイロ
３は、中の加圧状態が解放された後、縦軸方向に縮小せ

が位置して収納される状態を形成する（第７図参照）。Now, after the silo 3 has finished discharging the powder and granular material in this way, the pressurized state inside is released, and then it is reduced in the vertical axis direction and folded into the smallest state, and then the support Both ends 25 and 26 of the support arm 27 of No. 2 are removed from the support body 24 and the auxiliary cargo platform frame 22, and the support arm 27 is stored in an appropriate location on the vehicle body 1.
is folded inward of the vehicle body 1 and placed horizontally on the auxiliary cargo platform frame 22, and in this state, the support body 24 is
This becomes the lid 12 of the silo 3 that has been reduced and stored, and between this lid 12 and the loading platform 11, the silo 3 that has been reduced is

った。Reach! The present invention solves the problem in the above-mentioned prior art method in which the flexible silo is stretched and launched by pulling the flexible silo upward using a pantograph mechanism in the suspended state, that is, the pulling force is concentrated on a local part of the silo. This eliminates the problems of local damage to the silo and the need for a pantograph mechanism for each container, which increases the size and weight of the container. The silo is supplied with
A method is adopted in which pressurized fluid is supplied to stretch and stand up the silo, so that the force acting on the silo for starting up is applied to the entire inner wall surface of the silo, as seen in the prior art. By solving the problem of localized force acting on a part of the silo, and by using a pressurized fluid source prepared at the part where the powder and granules are received, the silo can be This eliminates the need to equip the silo with a launching mechanism, thereby solving the problems of conventional technology such as the increase in size and weight of the container.It also makes it possible to increase the size of the silo itself, which makes it especially bulky. It has become possible to provide a means suitable for conveying and supplying synthetic resin chips and pellets, which are said to have a low specific gravity.
