Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for pressure-feeding a fluid material in a storage container containing mainly powdered medicine or liquid to a desired location via a transport device in which a conical portion is connected to the container. The present invention relates to an apparatus for transporting fluids such as powder and granular materials.

In the pharmaceutical industry, from fixed source tanks that store large amounts of multiple types of powder and granular materials, the amount of material corresponding to the desired blending ratio is once stored in a portable sealed container with a lid, and then The container is carried to the installation position of a tumbler (rotating mixing tank), the blended materials in the container are thrown into the mixing tank and mixed uniformly, and the mixed materials are transferred to the container again.
Generally, a compounding and mixing transportation system is employed in which the materials are put into a hopper of a distribution transportation device installed at a predetermined location and supplied to a desired tablet making machine, packaging machine, or the like.

The present invention is capable of transporting a container containing materials taken out from a source tank by directly connecting it to a transport device, or transporting a container containing multiple types of materials without going through the complicated process described above. After mixing by rotating with an inverter,

The rotation mechanism Cc includes a reducer 14 driven by the motor M via a belt transmission mechanism V, and a manual handle 15 detachably connected to the outer end of the input shaft 14' of the reducer 14. The output shaft C'c is rotated by the drive of the motor M or by the rotation of the manual handle 15.The band-like metal fitting 13 of the holding mechanism Cd rotates the output shaft C'c.
The base C'd is fixed in the center to the base C'd, and a pair of left and right opening/closing parts 1 each have a pin hinge at each end thereof.
3', and a clamp ring 16' that is attached to the tip of one opening/closing part 13' and engages with the tip of the other opening/closing part 13' which is bent.
It consists of 6.

As shown in FIG. 1, this device having the above-mentioned configuration is constructed by loosening the nut 2c of the fastening tool 2 that tightens the storage container A and the lid 1, removing the lid 1, and replacing the transportation device B with the nut 2c. Turn the conical part 3 upside down, place its mouth rim db over the open mouth rim da of container A, seal the container A by tightening the fastener 2 again, and then turn the container A upside down. and then
By supporting the fitting part 3' of the conical part 3 on the upper side 4' of the conveying part 4, the material in the container A is allowed to flow down into the conical part 3 and connected to the discharge part 8 at the lower end of the conical part. After connecting a transport pipe to the connection part 9 and connecting the pressure air supply port 6a of the control box 6 to the discharge part 8 and the connection part 9 using piping, the pressure from the pressure supply device sent through the control box 6 is Air is supplied to the discharge section 8 and the connection section 9 to pump the material to the desired location. The connection operation of the conical part 3 and the storage container A, the reversal operation after connection, and the fitting operation with the conveyance part 4 can be performed only manually or by using the power of an existing hoist or the like. By using the reversing device C as shown in Figure 3 and below, these operations can be performed efficiently. For example, the container A, which has already contained the material, is placed on the elevating frame Cb of the reversing device C by hand or power, and the lid 1 and the conical part 3 are replaced as described above.
After operating the hydraulic pump 11 and link 12 to raise the elevating frame Cb to an appropriate height, close the belt-like metal fitting 13 of the reversing device C, which was left open during that time, and operate the tightening device 14 to raise the storage container A. The outer periphery of the container is held by the container holding mechanism Cd. Next, lift platform Cb
After lowering the container A, operate the manual handle 15 inserted into the input shaft 14' of the reducer 14 of the rotating mechanism Cc to move the conical part 3 together with the container A to the third position.
As shown in the figure, the transport device B is flipped downward, and as shown in FIG.
The transport section 4 is placed on the elevating frame Cb until the upper side 4' of the transport section 4 is fitted into the fitting part 3' of the conical section 3.
After raising the conical part 3 again and supporting the conical part 3 on the conveying part 4, operate the tightening tool 16 to close the container holding mechanism.
The storage container A is released from Cd, and the pedestal Cb is lowered and transported to a desired transport position.

When using the reversing device C as described above, if a plurality of types of powder and granular material according to the blending ratio are stored in the storage container A, and then mixed uniformly and transported, the first As shown by the imaginary line in Figure 5, the container A with the lid 1 attached is held by the container holding mechanism Cd of the reversing device C, the manual handle 15 is pulled out, the motor M is driven, and the container A is held together with the holding mechanism Cd. After rotating the container A to sufficiently mix the ingredients, turn the container A upward using the manual handle 15, then support it on the elevating frame Cb, and connect the lid 1 and conical part 3 in the same manner as described above. is replaced, supported by the transport section 4 of the transport device B, and carried out.

In the above embodiment, when placing the container A on the lifting platform Cb of the reversing device C, casters are fixed to the back surface of the bottom of the storage container A, or a transport frame equipped with casters and detachably connected to the container A is used. In some cases. Furthermore, although a drum-shaped stainless steel product was used for the storage container A in the embodiment, if the container body is made of paper, an inner bag made of synthetic resin film or the like may be used in combination. Furthermore, the apparatus used to carry out the present invention is not limited to the above-mentioned embodiments, but may include other means for sealing the container and the conical part, reversing means, conveying means, transportation means, etc. in accordance with the purpose of the present invention. It is also possible to change the embodiment as appropriate. Furthermore, in the case of transporting a liquid according to the present invention, it is possible, for example, by providing a pump at the discharge part of the conical part.

According to the present invention configured as described above and used as described above, since the storage container itself into which materials are transferred from a large source tank becomes the material supply tank of the transport device, it is especially possible to mix multiple types of powder and granular materials. When mixing, transporting, and transporting, the same container can be used consistently, and these operations can be performed with high efficiency. Also,
Since there is no need to replace the materials in the container when mixing or transporting the materials as in the past, it is possible to transport the materials in a closed system while avoiding scattering of the materials and unnecessary contact with air.
