Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for blending or blending and mixing a plurality of different types of fluid components, and particularly relates to a device for blending or blending and mixing two or more different fluid components, and in particular, a device for blending or blending and mixing two or more different fluid components. Relates to equipment for compounding or compounding and mixing.

More specifically, the present invention is directed to an apparatus that can be used to store, transport, dispense and mix, and extract at least two of the above fluid components. .

Unlike hydrodynamic liquids, most medium or multi-component adhesives, sealants and mastics contain some amount of entrained air, which is mixed into the components during formation or compounding. It is something that The degree of entrained air is
h′ [allowed and regulated for technical or commercial reasons. Historically, some of the fillers used in such ingredients are themselves compressible. For example, such compressible fillers include fine particles) J lame balls and air method. In addition, air bubbles are wrapped in the cars 1 to 2 that contain the ingredients when these ingredients are filled into the cars 1 to 2, and these 1-wrapped air bubbles are compressed and expanded during the extraction process. The cartridge is capable of expansion and contraction due to the movement of the supported end wall or the unsupported wall.

From the results above, it can be seen that while the back pressure from the nozzle is added and pressure is applied to the components, there is compression of the components and the components are extracted from the cartridge. Once the extraction pressure motive force is removed, a phenomenon is often observed where the component continues to flow out of the nozzle for a period of time during which the component expands.

This continued flow can be used as part of the extracted material for a particular operation, or it can be disposed of.

In general, such continued spillage does not severely affect the functionality of the cartridge in cartridges that extract single-component materials, and the nature of the continued spillage is negligible compared to the usefulness of such equipment. This is an acceptable shortcoming.

On the other hand, with multi-component or multi-component materials, the continued spillage problem is increased and complicated, which adversely affects the chemistry of the multi-component r1.

For example, when compounding multiple liquid components such as a reactive bamboo adhesive system from a cartridge such as a coaxial cartridge, or compounding and mixing, the probability that the above problem exists is high < 41. , some fluid components or ingredients continue to flow out more or less than the other ingredients or materials (
I like to play. This fact is due to the above factors, and furthermore, the unbalanced f due to the blending ratio of multiple components.
This is also due to the fact that the possibility of cotton swelling increases. A - Unlike the continuous flow of components, multi-component (A
As a result of the different continuous flow between the 11 materials, the blend ratio of the components will become incorrect at some point. This results in the extraction of small portions from mixing devices such as cartridges and series static pressure millimeters that are not in the correct ratio. There are many practical examples related to multiplex cartridge extraction of various two-component reaction systems.1. Since the Song Dynasty, there are only a few reaction systems that fall within the ♂1 volume limit of the predetermined two-component mixing ratio at the beginning and end of the outflow, and most of them are visually or in their performance unsuitable for J3C. It is determined whether a small portion of the ratio is to be extracted.

The overall benefit of the device is reduced by the need for some special skill or test procedure to control the quality at the beginning and end of the mixed component flow from multiple components. In some cases, this can actually lead to situations that are completely unacceptable. That is, as the user extracts a long bead of adhesive, the user discards the initial amount of extraction until a visible color change occurs indicating the correct predetermined mixing ratio. However, when small quantities are used, such as when the user repeatedly starts and stops to obtain a small portion of the mixed components, the production efficiency can be significantly reduced due to incorrect mixing ratios. Furthermore,
Many reactant systems do not undergo a visible color change between incorrect and correct ratios. This further increases the uncertainty in determining that the mixing ratio is correct.

The above problems can be solved to some extent by increasing the size of the mixer and nozzle to reduce outlet back pressure. However, large mixers and nozzles are usually not preferred in this type of reaction system.

This problem will be explained in detail below. That is,
When extracting by applying pressure to the J-tridge device, the less compressible material begins to flow before the other material, while the other material is compressed.

As the compression of the other material, ie, the highly compressible grain, increases, the flow of this other material increases until a two-component mass flows through the mixer at a desired predetermined mixing ratio. Therefore, after mixing the initial incorrect mix ratio with a high proportion of low compressibility Ce1, the mix components become correct.

When the extraction pressure is removed (11), materials with low compressibility, i.e., materials with high hydrodynamic properties, immediately stop flowing, but materials with high compressibility, i.e., materials with low hydrodynamic properties, immediately stop flowing. The flow continues for 4J.In this state, components with high compressibility and low water-like properties occupy the majority of the mixed components, and their occupancy is determined by low compression at the initial start-up operation in order to achieve a desired predetermined mixing ratio. This corresponds to a star of highly compressible material that should have flowed to the bulge 11.The final outflow at this cessation is an incommensurable ratio.The device is held back for a period of time to allow the bulge 11 to complete its action. This is because components with high compressibility and low hydrophilic properties will be contained in the extract at a high rate.Therefore, it is said that extraction is started by applying pressure again. In this case, a mixture with a high proportion of highly compressible materials is extracted first, followed by a mixture with a high proportion of low compressible components.The above chain of events determines when extraction starts. repeat between each cycle of stopping and restarting.However, during continuous use, the degree of compression and expansion will be reduced due to the reduced volume left in the cartridge chamber.For economical cartridge sizes, the capacity is There will always be a sufficient amount of heat to avoid the occurrence of the above-mentioned improper ratio mixing.

It will be appreciated that in a device for extracting at least two fluid components, the device is capable of stopping and starting the flow without creating a continuous flow and that even small portions, small shots, or small beats can be accurately extracted. It is desirable that it works.

In view of the above circumstances, it is an object of the present invention to provide an apparatus for blending and extracting, or blending, mixing and extracting at least two fluid components having different degrees of compression.

Such devices include a cartridge having a plurality of independent chambers for containing separate fluid components. A neck is provided adjacent the first discharge end of the cartridge. A plurality of independent passageways opening into separate chambers extend through the neck from the second end of the cartridge. Simultaneous application of pressure horns to the fluid components in separate chambers toward their first end compresses the fluid components to different degrees in concert with the resistance provided by the passages, causing the fluid components to be compressed to different degrees through each passage. Extracted at a predetermined mixing ratio.

In order to prevent continued outflow of the fluid component through each passage due to expansion of the fluid component when the pressure horn is removed, a configuration is provided to control the flow of the fluid component through each passage. , preventing fluid components from being extracted through each passage at a blending ratio other than the predetermined blending ratio. This configuration includes a valve member through which a plurality of channel portions extend. The valve member is mounted within the neck and has a first open position in which the flow passage portion is aligned with the respective passageway and extracts fluid components through the passageway at a predetermined formulation ratio;
The valve member is movable between first and a second closed position in which the valve member closes off the passage and prevents fluid components from flowing through the passage.

With the above configuration, continuous outflow of fluid components can be prevented. By moving the valve member to its closed position, the stiff passageway is closed and prevents continued spillage of any fluid components. Closing the passage in this way also
It is clear that the flow of the fluid components through the passageway is controlled, and furthermore, the closure of the passageway prevents the non-uniform continuous outflow of the plurality of fluid components, thereby preventing the above-mentioned extraction at an incorrect ratio. It is possible to prevent the formation of components.

Each chamber has a unique volume so that each fluid component is extracted at a desired predetermined mixing ratio.

The neck preferably extends forwardly from the first end of the cartridge.

The device may also be capped with a mixing extractor connected to the neck to receive the fluid components extracted through each passageway, and a plurality of fluid valves to mix the fluid components into a mixture component. can be extracted.

In an advantageous configuration of the invention, the mixing extraction device i may include a nozzle structure removably engaged to the surface of the neck. The nozzle structure fixes a mixing element that can perform mixing only by extraction pressure of fluid components, and is fitted with a part of the nozzle member such as a nozzle member placed at the discharge end of the neck and screwed onto the surface of the neck. This can include a flange-like coupling that holds the nozzle in place on the neck.
. Preferably, the valve member is mounted on the neck for rotation between the open and closed positions. In the preferred arrangement J3, the neck crosses multiple passageways 117i laterally.
7': Turn to the right the enlarged block section that has openings that intersect and intersect. The valve member has a stem portion pivotally fitted within the mouth. The channel section consists of two parallel holes extending through the slam section in a direction transverse to the axis of rotation of the slam section. This slim part is cylindrical and U'
b Good. Historically, the valve member has an irregularly shaped head which is located at the outer position of the first part and is integral with the first end of the stem part, and which enables engagement with the valve member rotation tab. It may be made to have a part. A device may be provided on the head to provide a visual indication of the orientation of the bore and whether the valve member is in the open or closed JL position. The second end of the stem portion may be provided with a groove at an external location of the block portion, into which a locking device is fitted to maintain the valve member within the block portion! But it's okay.

In a preferred configuration of the present invention, the plurality of independent chambers of the cartridge include a cylindrical first chamber and an annular second chamber coaxially surrounding the first chamber.

The first and second chambers contain first and second components, respectively, which solidify upon mixing.

Other objects, features and advantages of the invention will become apparent from the following detailed description of the preferred embodiments, taken in conjunction with the accompanying drawings.

Specific preferred embodiments of the invention will now be described with reference to the accompanying drawings. As a specific example, an apparatus for preparing, mixing, and extracting two fluid components that solidify when mixed is described.

As mentioned above, these two components have different degrees of compression.

The two components C may be known adhesives, sealants, or Masdec-based components, or may similarly be other materials that solidify when mixed, as is obvious to those skilled in the art.

However, it should be noted that the present invention is not limited to two-component systems, but can also be used for systems that can prepare, mix, and extract two or more components.
“I want to be treated like that.”

Furthermore, the present invention is intended to be directed to devices for dispensing and extracting multiple fluid components, as well as devices for dispensing, mixing, and extracting multiple fluid components.

The device of the invention has a cartridge, generally designated by the reference number 2, in which a first cylindrical, e.g.
A chamber 4 and, for example, an annular second chamber 6 surrounding the chamber 4 are provided. , these two chambers are completely independent of each other, each containing fluid components of different degrees of compression that are assimilated when mixed.

A neck portion 8 extends forward from the protruding ends 11 of the cars 1 to 2. The neck part 8 has a first opening with a total of 4.6 holes.
And the second passage 10.12 is the shellfish passage C.

The second ends of the chambers 4, 6 are each hermetically closed with a closing member 1/1.16.

Simultaneous application of pressure to the closure IJ171.16, ie to the fluid components of chambers 4, 6, forces the fluid components towards the discharge end of the car 1-ridge. aisle 10
．． The two fluid components tend to compress due to the back pressure created by the resistance at 12 and also due to the mixing device attached to the blind section 8, which will be explained in more detail below.

This J: Una compression occurs due to the above reasons,
However, the two components have different degrees of compression. Passage 1
With the 0.12 open, the less compressible fluid component begins to flow out through its passage first. Initially, since the more compressible fluid components tend to compress, the outflow of 'C through the corresponding passages is delayed until the compression is complete. After this initial misratio condition,
As further extraction pressure is applied, the two fluid components are extracted through each passageway 10.12 in a desired predetermined mixing ratio.

However, when the extraction pressure is removed, the two fluid components tend to expand. Therefore, two consecutive outflows indicate a strong tendency. Moreover, because the compressibility of the two fluid components is different, the extent of this continued flow will also be different. This results in the inappropriate ratio part described by J.

According to the invention, an arrangement is provided for controlling the flow of two fluid components through the passages 10.12, such that upon removal of the extraction pressure horn, the flow of the two fluid components through each passage 10.12 due to expansion of the fluid components. More specifically, such arrangements according to the present invention include a valve member, generally indicated by the reference numeral 18. Valve member 18 preferably comprises (

The valve member 18 is pivotable so that the stem portion 20 is pivotable in a sealed manner within an opening 26 passing through the enlarged cock portion 28 of the neck 8.

More specifically, the passageway portions 22.2/I are aligned with corresponding passageways 10.12 to facilitate extraction of fluid components through the passageways in a desired predetermined formulation ratio. In the open position shown in FIG. 1 and FIG.
．． 12 is not aligned and the passage 10.12 is blocked by the valve member, thereby completely preventing the flow of fluid components through the passage.
is rotatable relative to the block portion 28.

The valve member has a C1 head 30 at its first end. The head part 30 is located at the outer side of the block part 28.
It has an angular shape such as a hexagonal shape, and a tool for rotating the valve member can be engaged therewith. An alignment device, such as a linear indicator 32, may be provided on the head 30 to indicate the orientation of the hole 22.2/I;
A groove is provided at the second end of the valve portion 20 at an outer position of the block portion 28. [)] and [1] A suitable element, such as a ring 34, may be inserted into this vortex to allow the valve member 18 to
It may be possible to hold the .

Valve part I from the position shown in Figure 1 to the position shown in Figure 2
It is clear that rotating 418 will stop the flow of fluid components through passageway 10.12.

This prevents the above-mentioned continued outflow, unequal continued outflow of the chamber components, and the consequent small portion of the incorrect ratio of -C.

According to a further embodiment of the invention, reference numeral 36 is shown in FIG.
A mixing extraction device 36 is provided connected to the neck 8, shown generally at .
．． 12, which receives a plurality of fluid components extracted from I
The purpose of this method is to mix a plurality of fluid components to form a mixed component having a desired predetermined mixing ratio, and then to extract this mixed component. Such a configuration has a nozzle removably connected to the surface of the neck ε3. Specifically, the nozzle member 38 is disposed at the III protruding end of the neck 8, and the nozzle member 38 is , a mixing Jnirement/IO that performs mixing only by the extraction pressure of the fluid components is fixed inside thereof.7 A flange-shaped coupling 42 is fitted into a part of the nozzle member 38, and furthermore, the neck part 8 The nozzle member 38 is held in place relative to the neck. The mixing extractor 36 is intended to be a static mixer 6 in series. .From the configuration shown in Figure 1,
It is clear that the two fluid components do not come into contact until the fluid components are discharged into the interior of the nozzle portion t7A' 38. Thus, there is no mixing and assimilation of the two fluid components at a point where the device 3G on the neck 8 is removed, and the device 36 can be immediately removed if desired. The two fluid components are the car 1-ridge 21 neck 8 and valve member 1.
Part 8 never mixes.
