BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus for transferring and filling a fluid, and more particularly, a method for transferring and filling a filled container into a container to be filled in a defoamed state of a liquid or pasty fluid, and suitable for carrying out the method. Relates to the device.
[0002]
[Prior art]
For example, fluid such as epoxy resin is used by stirring and mixing the raw material composition, defoaming the fluid, and transporting and filling the defoamed fluid into a filled container (syringe). That is, first, stirring and mixing of the raw material composition are performed in a stirring vessel in which bubbles generated by stirring and mixing are easily removed. After that, the defoamed fluid is transferred to another pressure-feeding container, and further compressed by a compression piston and filled into the filling container. The stirring vessel is generally set to have a length (depth) of about twice or less with respect to the diameter in terms of work efficiency such as easy stirring / mixing and defoaming.
[0003]
FIG. 4 schematically shows an embodiment of a means for pumping and filling (injecting) a fluid that has been stirred, mixed and degassed into a container to be filled used in, for example, a coating operation. In FIG. 4, 1 is a pressure feeding container, 2 is a defoamed fluid transferred from the stirring container into the pressure feeding container 1, and 3 is a compression for pumping the fluid 2 in the pressure feeding container 1 to the filled container 4. The piston 5 is a pressure-feeding pipe for pressure-feeding compressed air, and 6 is a compressed-air pump. Here, the compressed air compressed by the compressed air pump 6 drives the compression piston 3 to be pumped through the pumping pipe 5 to transfer the fluid 2 in the pumping container 1 to the filled container 4. Fill.

[Problems to be solved by the invention]
However, the fluid filling means has the following disadvantages. That is,
(A) The fluid defoamed in the stirring vessel tends to easily contain air bubbles by entering the fluid 2 that has been defoamed in the course of being transferred from the stirring vessel to the pressure feeding vessel 1.
(B) In the region where the container for transporting 1 is transported and filled from the container 1 for pressure feeding, outside air is caught in the transporting path, and the defoamed fluid 2 is likely to mix air.
(C) Since the compression piston 3 is mounted and inserted after the fluid is transferred from the stirring vessel to the pressure feeding container 1, residual air is sandwiched between the fluid 2 and the compression piston 3, and the air is fed in the pressure feeding process. There is a risk of getting involved. Therefore, when attaching / inserting the compression piston 3, careful attention and ingenuity are required so that residual air is not caught.
(D) When the container 4 to be filled is arranged vertically and the fluid 2 is transferred and filled from the lower end side, smooth filling is difficult depending on the viscosity of the fluid.
(E) Since there are many members constituting the means or apparatus, much labor and cost increase are required for the maintenance. That is, when repeatedly used, it takes a cleaning operation of the decomposition-member, to discard or a waste of expensive fluid 2 to adhere to the member, or in each case member, which lead to up significant running costs .
