Description

Technical Field

[0004] , ,

[0001] The present invention relates to a two-component mixed type applicator that generates, for example, a coating agent by mixing a main agent with a curing agent or the like, and supplies the coating agent or the like to an application object through a valve mechanism.

Background Art

[0002] A two-liquid discharge container that can discharge two types of solutions quantitatively or at the same ratio has been proposed (Patent Document 1). According to this two-liquid discharge container, two container bodies containing solutions are respectively housed in a cover case, and by operating a rotation operation part arranged at the rear part of the cover case, each piston that moves forward in conjunction with the rotation operation part causes the solutions housed in the respective container bodies to be pushed out. According to this, the respective solutions housed in each container body are discharged quantitatively or at the same ratio from each nozzle arranged at the front part of the cover case.

[0003] In addition, an extrusion type kneading device has been proposed that includes first and second accommodating parts for separately accommodating two types of fluid materials, and introduces the fluid materials extruded from the first and second accommodating parts into a kneading cylinder in which a static mixer is housed (Patent Document 2). According to this extrusion type kneading device, the static mixer repeats confluence and division several times for two types of fluid materials, so that the mixed two types of fluid materials can be led out from the kneading cylinder.

[0004] Furthermore, a two-liquid mixing container has been proposed in which a partition body that is axially movable is arranged in a cylindrical container body, and the container body is divided into front and rear two chambers by this partition body, and fluid materials are separately accommodated in each chamber (Patent Document 3). This two-liquid mixing container is equipped with a push-up member that can move the partition body, and by moving the partition body to the part of the container body where the inner diameter expands outward using this push-up member, it is possible to mix two types of fluid materials. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2005-212843 [Patent Document 2] Japanese Patent Publication No. 2000-317287 [Patent Document 3] Japanese Patent Publication No. 2010-155639 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Incidentally, the two-component dispensing container disclosed in Patent Document 1 is intended to dispense solutions in a predetermined ratio, and as described in Patent Document 1, it does not have the function of mixing and applying the two solutions. Furthermore, the extrusion-type kneading apparatus disclosed in Patent Document 2 requires a kneading cylinder to house a static mixer for mixing the two liquids, which presents the problem of making the entire apparatus long and large.

[0007] Furthermore, according to the two-liquid mixing container disclosed in Patent Document 3, the two liquids can be mixed by moving a partition separating the two liquids using a push-up member, thereby moving the partition to a portion of the container body where the inner diameter expands outward. However, this presents a problem in that sufficient stirring and mixing of the two liquids cannot be achieved.

[0008] This invention aims to solve the aforementioned problems of conventional two-component mixing type applicators. It provides a two-component mixing type applicator that allows the two liquids to be mixed by releasing the seal (seal) provided by the sealing body that separates the two liquids, and that can provide sufficient stirring and mixing action to the two liquids by making the released sealing body usable as a stirring body for the two liquids. [Means for solving the problem]

[0009] The two-component mixing applicator according to this invention, made to solve the aforementioned problems, is a two-component mixing applicator in which a first storage chamber for solution A and a second storage chamber for solution B are arranged at the front and rear of a shaft, and a mixed solution of solution A and solution B is supplied to an applicator arranged at the front end of the shaft, wherein the solution A and solution B are isolated by a sealing body fitted and arranged between the first and second storage chambers, and the sealing body and solution B are introduced into the first storage chamber when the sealing body is released, and the free movement of the sealing body within the first storage chamber due to shaking the shaft causes the sealing body to function as a stirring body for mixing the solution A and solution B.

[0010] In this case, the shaft is composed of a front shaft that supports the coating body, a first rear shaft having the first housing chamber, and a second rear shaft having the second housing chamber which is attached to the first rear shaft so as to be able to move toward and away from it. When the second rear shaft approaches the first rear shaft to a predetermined position, the sealing body which is fitted and positioned between the first housing chamber and the second housing chamber is pushed by the second rear shaft to release the seal. A more preferable configuration for achieving this is one in which the first and second rear shafts are each provided with female and male threads that are screwed together and can move toward and away from each other by relative rotation.

[0011] On the other hand, it is desirable that a stopper is detachably attached between the first rear axle and the second rear axle to prevent the second rear axle from approaching the first rear axle to the predetermined position.

[0012] Furthermore, a valve mechanism that maintains a closed state at all times is positioned between the coating body located at the front end of the shaft and the first containment chamber. In this case, preferably, the valve mechanism comprises a valve cylinder that constitutes the outer casing of the valve mechanism, a coil spring with one end in contact with the valve cylinder, a valve stem that receives the biasing force from the other end of the coil spring, and an annular valve seat body having a valve seat that receives contact with the valve body due to a tapered surface formed on the valve stem. The valve mechanism is opened when the front end of the valve stem is positioned inside the annular valve seat body and receives contact with the coating body. [Effects of the Invention]

[0013] According to the two-component mixing applicator of this invention, solution A and solution B are stored in isolation by a sealing body fitted and positioned between the first and second storage chambers. When using the mixed solution of solution A and solution B, the sealing body is released, and the sealing body and solution B are introduced into the first storage chamber. In this state, by shaking the shaft, the sealing body can be moved freely within the first containment chamber, allowing the sealing body to function as a stirring body for the two liquids, solution A and solution B. Therefore, it is possible to provide a two-component mixing device that can provide sufficient stirring and mixing action to the two components. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0015] The two-liquid mixing type applicator according to this invention will be described based on the embodiments shown in the drawings. In each of the following figures, the same parts are denoted by the same reference numerals. However, in the overall configuration diagrams shown in FIGS. 1 to 6, for convenience of the drawing, representative parts are labeled with reference numerals, and for details of each part, the reference numerals shown in the exploded view of the components shown in FIG. 7 or the single-component structure diagrams of the components shown in FIGS. 8 to 11 will be cited for explanation. In the following description of the two-component mixing type applicator, the side on which the applicator is located will be referred to as the "front," and the opposite side will be referred to as the "back."

[0016] Figures 1 and 2 show the external configuration of this two-component mixing type applicator. A cylindrical cover body 2, also cylindrical and with its rear end closed, is detachably attached in the axial direction to the rear end of a cylindrically formed first rear shaft 1. Preferably, the first rear shaft 1 and the cover body 2 are made of an aluminum alloy having the same outer diameter. The inside of the first rear shaft 1 constitutes a first containment chamber 1a for containing solution A. Furthermore, a front shaft 3 is attached to the front end of the first rear shaft 1, and a cap 4 is detachably attached so as to cover the front end of the front shaft 3. As a result, the appearance of the two-component mixing type applicator is that of an elongated cylindrical body. In this example, the front shaft 3 and the cap 4 are preferably made of resin material.

[0017] As shown in Figure 2(B), a reduced-diameter section 1b is integrally molded at the rear end of the first rear shaft 1. A cylindrical sealant receiving section 5 made of resin material is fitted and installed inside this reduced-diameter section 1b. A sealant 6 made of metal balls is fitted and positioned inside the front half of the sealant receiving section 5. A second rear shaft 7 is screwed into the rear half of the sealant receiving section 5, and the inside of the second rear shaft 7 constitutes a second storage chamber 7a for containing the solution B. Therefore, solution A in the first rear shaft 1 and solution B in the second rear shaft 7 are stored in isolation by a metal ball seal 6.

[0018] Furthermore, a stopper 8 is detachably attached between the first rear axle 1 and the second rear axle 7 to prevent the second rear axle 7 from approaching the first rear axle 1 to a predetermined position. As described later, the seal provided by the sealing body 6 can be released by removing the stopper 8 and screwing the second rear shaft 7 toward the first rear shaft 1. As a result, the sealing body 6 made of metal balls is introduced into the first containment chamber 1a, and the solution B in the second containment chamber 7a is introduced into the first containment chamber and mixed with the solution A.

[0019] In this state, the free movement of the sealing body 6 within the first containment chamber 1a due to shaking the applicator allows the sealing body 6 to function as a stirring body (first stirring body) for mixing and stirring solution A and solution B. Therefore, the aforementioned stopper 8 is provided to prevent the two-component mixing device from being unintentionally mixed when it is not in use. Further details regarding the first rear shaft 1, the sealing body receiving portion 5, the second rear shaft 7, and the stopper 8 will be described later based on the individual component diagrams.

[0020] On the other hand, as shown in Figure 2(B), a coating body 9 is arranged in the front end opening 3a of the front shaft 3 so as to be movable in the axial direction, and a valve mechanism 11 that maintains a closed state at all times is arranged between this coating body 9 and the first housing chamber 1a of the first rear shaft 1. In this embodiment, the shaft cylinder 12 is composed of the front shaft 3, the first rear shaft 1, and the second rear shaft 7, and the first storage chamber 1a for storing solution A and the second storage chamber 7a for storing solution B are arranged at the front and rear of the shaft cylinder 12.

[0021] Furthermore, the mixed solution of solution A and solution B, generated by the release of the ball-shaped sealant 6, is supplied to the coating body 9 located at the front end of the shaft cylinder 12 via the valve mechanism 11. Furthermore, when this two-component mixing applicator is in unused storage condition as shown in Figure 2, the second stirring body 13, which consists of a small metal ball housed inside the second rear shaft 7, acts to stir the solution B in the second storage chamber 7a by shaking the shaft 12.

[0022] Figure 8 shows the individual components of the first rear shaft 1. As previously explained, this first rear shaft 1 constitutes the first containment chamber 1a for containing solution A. A reduced-diameter portion 1b with a slightly reduced outer diameter is integrally molded at its rear end, and the sealing body receiving portion 5 is fitted and attached within the reduced-diameter portion 1b. Furthermore, a diameter-reducing portion 1c is integrally molded on the front end of the first rear shaft 1, slightly reducing its outer diameter, and a male thread 1d is formed on its outer surface. The female thread 3b (see Figure 2(B)) on the front shaft 3 is screwed into this male thread 1d, thereby attaching the front shaft 3 to the front end of the first rear shaft 1. Furthermore, the aforementioned configuration of the first rear shaft 1 can be formed by, for example, drawing a pipe material made of aluminum alloy.

[0023] Figure 9 shows the individual components of the sealing body receiving part 5. This sealing body receiving part 5 is generally formed in a cylindrical shape, and the outer diameter of the rear end of this cylindrical shape is formed to be slightly larger, with this larger diameter portion functioning as a fitting surface 5a to the first rear shaft 1. A flange portion 5b is formed at the rear end of the sealing body receiving part 5, and this flange portion 5b abuts against the rear end of the reduced diameter portion 1b of the first rear shaft 1, thereby positioning and attaching the sealing body receiving part 5 to the first rear shaft 1. Furthermore, an arc-shaped recess is formed along the inner circumference of the front end side of the sealing body receiving portion 5, and this arc-shaped recess functions as a sealing body holding portion 5c into which the sealing body 6 made of the metal ball described above is fitted and attached. Furthermore, a female thread 5d is formed on the inner circumferential surface of the sealing body receiving portion 5, from the center towards the rear. This female thread 5d is used to attach the second rear shaft 7.

[0024] Figure 10 shows the individual components of the second rear shaft 7. This second rear shaft 7 is made of resin material, and the bottomed cylindrical portion 7b forms a second storage chamber 7a that contains the solution B. Furthermore, a long, narrow opening 7c is formed at the front end of the cylindrical portion 7b, and the base portion of this opening 7c closer to the cylindrical portion 7b constitutes a stopper mounting portion 7d to which the stopper 8 is detachably attached. Furthermore, the front end of the opening 7c adjacent to the stopper mounting portion 7d has a slightly reduced diameter to form a male thread 7e. This male thread 7e is screwed into the female thread 5d of the sealing body receiving portion 5, which is fitted and attached to the first rear shaft 1, thereby attaching the second rear shaft 7 to the first rear shaft 1.

[0025] As a result, by rotating the second rear shaft 7 relative to the first rear shaft 1, the second rear shaft 7 acts to move closer to and further away from the first rear shaft 1. In other words, in this embodiment, the first rear shaft 1 and the second rear shaft 7 are each provided with a female thread 5d and a male thread 7e, respectively, which are screwed together and can move toward and away from each other by relative rotation.

[0026] Figure 11 shows the individual components of the stopper 8. This stopper 8 is formed by opening a ring-shaped portion and molding it into a C-shape to create an opening 8a, and is made of an elastically deformable resin material with a predetermined width along its circumference. On either side of the opening 8a, a pair of protruding gripping portions 8b are formed, extending outwards. This stopper 8 is attached to the stopper mounting portion 7d of the second rear axle 7. When attaching the stopper 8, the opening 8a of the stopper 8 is pushed toward the stopper mounting portion 7d of the second rear axle 7, causing the opening 8a to elastically deform and expand, thereby allowing it to be attached so as to surround the stopper mounting portion 7d of the second rear axle 7. Furthermore, to remove the stopper 8, the pair of gripping parts 8b are used to grasp the stopper 8 in a direction perpendicular to the axis and pull it out, which similarly causes the opening 8a to elastically deform, allowing for easy removal.

[0027] Next, the configuration of the valve mechanism 11 provided in the two-component mixing type applicator according to this invention will be explained based on the exploded view of the parts shown in Figure 7. This valve mechanism 11 consists of a valve cylinder 21, a coil spring 22, a valve stem 23, and a valve seat 24. The valve body 21 constitutes the outer casing of the valve mechanism 11. An annular flange 21b is formed at its front end opening 21a, facing outwards. At its rear end, the diameter is slightly reduced, and multiple (four) side wall openings 21c are formed at equal intervals along the circumferential side wall. These side wall openings 21c introduce the mixed solution stored in the first storage chamber 1a of the first rear shaft 1 into the valve body 21.

[0028] Furthermore, a valve body 23a having a tapered surface that decreases in diameter toward the front is formed in the longitudinal center of the valve stem 23, and a rod-shaped portion 23b is formed at the rear of the valve body 23a, and the aforementioned coil spring 22 is mounted so as to surround this rod-shaped portion 23b. The valve stem 23 and the coil spring 22 are housed in the valve cylinder 21, and the rear end of the coil spring 22 abuts against the inner wall on the rear end side of the valve cylinder 21. The front end of the valve stem 23 constitutes a cylindrical body 23d having a front end opening 23c.

[0029] A valve seat 24, which is formed in an annular shape, is fitted and attached to the front end opening 21a of the valve cylinder 21. The front end of the coil spring 22 abuts against the back surface of the valve body 23a formed on the valve stem 23, and under the biasing force of the coil spring 22, the cylindrical body 23d located on the front end side of the valve stem 23 is positioned to protrude forward from the opening 24a of the valve seat 24. As a result, the valve body 23a, which has a tapered surface formed on the valve stem 23, comes into contact with the valve seat 24c, which is the rear end opening of the valve seat body 24, and the valve mechanism 11 maintains a closed state.

[0030] By pushing the valve seat 24 against the valve cylinder 21 until the flange 24b formed at the front end of the valve seat 24 abuts against the flange 21b of the valve cylinder 21, the valve seat 24 is fitted into the valve cylinder 21 and the valve mechanism 11 is assembled. The flange portion 21b of the valve cylinder 21 and the flange portion 24b of the valve seat 24 are sandwiched between the front end opening edge of the first rear shaft 1 and the annular stepped portion formed inside the front shaft 3, so that the valve mechanism 11 is positioned and arranged inside the front end opening of the first rear shaft 1 [see Figure 2(B)]. Furthermore, a cylindrical solution storage body 25, which is provided with a shaft hole 25a, is placed inside the front shaft 3. This solution storage body 25 is made of, for example, a sponge such as urethane, or felt, and is positioned in contact with the front end of the valve mechanism 11.

[0031] The procedure for the coating operation using the two-component mixing type applicator described above will be explained with reference to Figures 3 to 6. Figure 3 shows the initial operating procedure when using this two-component mixing type applicator. First, remove the cover cylinder 2 attached to the rear of the first rear shaft 1 of the applicator, and remove the stopper 8 that is installed between the first rear shaft 1 and the second rear shaft 7.

[0032] In this state, by shaking the applicator, the second stirring body 13, housed in the second containment chamber 7a of the second rear shaft 7, can move freely within the second containment chamber 7a and stir solution B. This stirring operation of solution B can also be performed in the state shown in Figure 2 before removing the stopper 8. Next, the second rear shaft 7 is screwed onto the first rear shaft 1, causing the second rear shaft 7 to approach the first rear shaft 1, and the opening 7c of the second rear shaft 7 to press against the metal ball seal 6. As a result, the seal 6 is released from the seal receiving part 5 and introduced into the first containment chamber 1a.

[0033] Figure 4 shows the state in which the sealing body 6 has been introduced into the first containment chamber 1a. In the state shown in Figure 4, the first containment chamber 1a and the second containment chamber 7a are in communication, so the solution B contained in the second containment chamber 7a is introduced into the first containment chamber 1a together with the second agitator 13. In this state, by shaking the applicator, the sealing body 6 introduced into the first containment chamber 1a functions as a first stirring body that agitates and mixes solution A and solution B. In this case, the second stirring body 13 also contributes to the agitation and mixing of solution A and solution B.

[0034] Figure 5 shows an example of a pumping operation performed in which the stirred and mixed solution is supplied to the coating body 9 within the first containment chamber 1a. In the state shown in Figure 5, the cover cylinder 2 is attached to the rear of the first rear shaft 1, and the cap 4 is removed from the front shaft 3. Then, the coating body 9 protruding from the front shaft 3 is pressed against the object to be coated or any other object.

[0035] As a result, the coating body 9 retracts within the front shaft 3, causing the valve stem 23 of the valve mechanism 11 located immediately behind it to retract against the biasing force of the coil spring 22. Consequently, the valve body 23a formed on the valve stem 23 opens away from the valve seat 24c of the valve seat body 24, and the mixed solution in the first containment chamber 1a is supplied to the solution absorber 25 and the coating body 9 through the opening 24a of the valve seat body 24. Furthermore, when the pressure on the coating body 9 is released, the biasing force of the coil spring 22 causes the valve body 23a to contact the valve seat 24c of the valve seat body 24, closing the valve and stopping the flow of the mixed solution supplied from the first containment chamber 1a to the solution absorber 25 and the coating body 9.

[0036] Figure 6 shows that, after the pumping operation described above is completed, the coating body 9 is in a forward position due to the biasing force of the coil spring 22, and is ready for coating. In this state, a certain amount of mixed solution is stored in the solution storage body 25, and acts to smoothly supply the solution from the solution storage body 25 to the coating body 9. Therefore, by repeatedly performing the pumping operation shown in Figure 5 as the coating operation by the coating body 9 progresses, a continuous and stable coating operation can be achieved.

[0037] The aforementioned coating body 9 is constructed by bundling synthetic fibers together in a cylindrical shape and shaping both ends in the longitudinal direction into cones, so that either end in the longitudinal direction can be used as a coating area. Therefore, its appearance consists of a central cylindrical part and conical parts formed at both ends thereof.

[0038] The following describes suitable liquids for use in the two-component mixing type applicator according to this invention. This containment liquid consists of a two-component mixed solution comprising a main agent and a curing agent. Examples of two-component mixed solutions include acrylic coating agents, epoxy coating agents, and urethane coating agents. It is preferable to add a photosensitizer, a photocurable component, and a photopolymerization accelerator as coating agent components. Furthermore, the coating agent may contain an organic solvent, and it is more preferable that the resin component in the coating agent composition is contained in an amount of 10 to 100% by mass, as this improves the abrasion resistance of the coating film.

[0039] For example, when using an epoxy coating agent, an epoxy compound is used as the main component (solution A), and a curing agent for epoxy compounds (photosensitizer) is added as the curing agent (solution B). A viscosity of 1 mPa·s to 100 mPa·s is preferred. More specifically, a solution is used as the main component (solution A) by mixing 50 parts epoxy resin varnish and 50 parts photocurable epoxy resin varnish, and a solution is used as the curing agent (solution B) by dissolving 100 parts of liquid posisulfide composition with 3 parts allylcyasonium hexafluorophosphate as a photosensitizer. Preferably, the ratio of solvents is such that the main component is greater than the curing agent.

[0040] Furthermore, the two-component mixing type applicator according to this invention can be suitably used not only for the coating applications described above, but also as an applicator for two-component adhesives for bonding applications, and similar effects can be obtained.

[0041] In the embodiment described above, a metal ball is used as a sealant 6 that seals the first storage chamber 1a containing solution A and the second storage chamber 7 containing solution B, and also functions as a stirring element that stirs and mixes solution A and solution B when the seal is released. However, the sealant 6, which also serves as a stirring element, can be made of various shapes other than a ball shape. Furthermore, the sealant 6, which also serves as a stirring element, can preferably be made of a material other than metal, having a specific gravity greater than that of solutions A and B.

[0042] Furthermore, in this embodiment, in order to release the seal provided by the sealing body 6, the first rear shaft 1 constituting the first housing chamber 1a and the second rear shaft 7 constituting the second housing chamber 7a are screwed together by female threads 5d and male threads 7e, respectively, and are configured to move toward and away from each other by relative rotation. However, without forming female and male threads, it is also possible to adopt a configuration in which the first rear shaft 1 and the second rear shaft 7 can move toward and away from each other, for example, by connecting them so that they can slide toward each other in the axial direction.
