Description

[0001]
【Technical field】
The present invention relates to a method and an apparatus for charging a viscous material by inserting a container filled with a viscous material into a pressure-resistant container, and pressing and deforming the viscous material container with the pressure of gas supplied into the pressure-resistant container. It is used when discharging agents, inks, creams, and other viscous materials continuously or intermittently.
[0002]
[Prior art and its problems]
As this type of viscous material discharging method or apparatus, those disclosed in JP-A-61-117367 and JP-B-5-39384 are known.
In the former known technique, an adhesive container is inserted horizontally into a pressure vessel placed sideways, and a pressure gas is applied to the pressure vessel to cause the adhesive container to be pressed and deformed to be brought into contact with a repair site. The adhesive is directly discharged from the spout of the agent container to the repair site.
However, in this known technique, since the cylindrical adhesive container is loaded sideways, when pressurized gas is introduced into the pressure resistant container, the gravity of the adhesive is directed downward, that is, laterally with respect to the spout. If the adhesive container is pressed in a state where the adhesive is applied, the container will be deformed into an indeterminate shape, making it impossible to stably discharge the adhesive, and the side wall of the container will be deformed downward to close the spout. If this happens, the discharge of the adhesive stops at that stage. Although an example in which the adhesive container is pressed by the piston is also shown, there is an inconvenience that irregular wrinkles are generated in the container pressed by the piston and the adhesive remains between the wrinkles.
In addition, since the spout of the adhesive container is directly exposed to the outside of the pressure resistant container, there is a disadvantage that it cannot be used for purposes other than injection of the adhesive into the repaired portion of the side wall.
[0003]
In the latter known technique, the main body of the injector is composed of a cylindrical body divided into an inner and outer double, a cylindrical adhesive cartridge made of a thin film is inserted into the inner cylinder, and a chemical reaction heating means is provided in the outer cylinder. It is provided. When connecting the injector to the pipe of the attachment fixed on the crack, a hole is made in the tip of the cartridge by a protrusion provided on the pipe, and the cartridge is generated by the gas generated by the gas generating means by chemical reaction attached to the inner cylinder. Is pressed and deformed to discharge the adhesive.
However, in this configuration, the cylindrical cartridge is subjected to gas pressure on the entire outer surface thereof, so that it is irregularly deformed and wrinkles are generated on the film. If it does so, discharge of a viscous material will not be stabilized and the adhesive agent which is not discharged with a wrinkle will remain in large quantities. Moreover, since the injector itself becomes disposable, it is extremely uneconomical.

[Technical issues]
The present invention relates to a method and apparatus for charging a viscous material by inserting a container filled with a viscous material into a pressure-resistant container, and pressing and deforming the viscous material container with the pressure of gas supplied into the pressure-resistant container. An object of the present invention is to stabilize the deformation during pressing.
[0005]
[Technical means]
The first technical means for solving this technical problem relates to a viscous material discharge method. (A) A viscous material container is formed of a flexible film material and is suspended in a pressure resistant container. (B) discharging the viscous material out of the pressure vessel directly or through the discharge pipe provided at the lower portion of the viscous material container.
The second technical means relates to the viscous material discharge device, and (c) a locking portion for suspending the viscous material container formed of a flexible film material is provided on the inner upper part of the pressure vessel. ) The spout provided in the lower part of the viscous material container is communicated with the discharge pipe of the pressure resistant container.
[0006]
The third technical means is to attach the locking portion used for the apparatus via a spring body, and the fourth technical means is that the top of the viscous container used in the method and apparatus is linear. The seal part is provided.
[0007]
Since the viscous material container is formed of a flexible film material, the container is easily pressed and deformed as the viscous material is discharged by gas pressure.
In the pressure vessel, pressure is applied evenly from the surroundings of the viscous material container, but the viscous material container is suspended in the pressure resistant container, so the viscous material filled inside will face downward due to its own weight. The pressure is applied. Therefore, if the viscous material is discharged from the spout provided at the bottom of the viscous material container by the pressure action of both, the container is gradually crushed from the top side, so the viscous material container becomes irregular. The deformation of the container can be stabilized without being crushed.
[0008]
The flexible film material constituting the viscous material container is appropriately selected in consideration of solvent resistance, gas barrier property, moisture barrier property, etc. according to the type and properties of the viscous material, and is a single film or laminated film. Will be used.
If the viscous container has a linear seal at the top, the container will be crushed starting from the seal, so the opposing side walls will be in close contact and the container will be deformed flat. Therefore, no soot is generated, and the residual amount of viscous material, that is, the loss can be extremely reduced. In this case, when the bottom is circular, it is desirable to provide a spout on the bottom, and when the bottom is also provided with a linear seal, a spout is provided at the bottom of the side surface or the bottom A spout is projected downward from the seal portion.
This spout may be attached separately. In this case, it is necessary to make a hole in the wall of the container inside the adhered spout.
In addition, when using a sausage-type viscous material container, it is desirable to stick the spout formed separately on the lower side wall.
[0009]
As long as the adhesive filled in the viscous container is protected, the gas supplied into the pressure container is not particularly limited. Air can be used as a simple gas.
The spout of the viscous container can be discharged out of the pressure container by communicating with a discharge pipe attached to the pressure container. In this case, if the discharge pipe is made flexible, even if there is a difference in the size of the viscous material container, it can be easily communicated.
Of course, the spout of the viscous container may be directly communicated with the discharge part of the pressure container, but in this case, the size of the viscous container may be limited.
[0010]
It is desirable to hang the viscous material container on the inner upper part of the pressure container, that is, on the inner wall upper part or the engaging part provided on the back surface of the lid. As the locking portion, a hook can be preferably used, but the ring can be protruded and suspended using a string or a locking ring. You may make it make a hook protrude on the top part of a viscous container, and to hook this on the latching | locking part by the side of a pressure container.
It is also possible to arrange a frame having a locking portion in the pressure vessel and hang the viscous material container on the frame.
When the locking part is attached to the pressure vessel via a spring, even if the container gradually extends in the vertical direction as the viscous material is gradually discharged, the weight of the viscous material filled is reduced accordingly. Since the container is gradually pulled up by the contraction of the spring, there is no possibility that the viscous material container buckles or closes in the middle.
[0011]
[Effect of the present invention]
As a result of stabilizing the deformation of the viscous container when it is pressed, the discharge amount can be stabilized, and there is an advantage that the amount of viscous substance remaining in the container, that is, the loss can be greatly reduced.
The stable pressure deformation of the viscous container has an advantage that the volume of the dust can be reduced because the volume of the container after use is reduced.
