Japanese Unexamined Patent Publication No. 2016-159236

In a conventional fluid mixing discharger, a mixing blade is formed by continuously forming spirally twisted blades while alternating the twisting direction of the blades on the left and right. The mixing blades are mixed by spirally flowing a liquid (fluid) such as a main agent and a curing agent. Even if the main agent and the curing agent are mixed in a predetermined ratio, the two-component curable adhesive may not have an appropriate adhesive strength if the mixing is insufficient. Therefore, the mixing blade needs to be formed long in order to sufficiently mix the fluid, and the nozzle for arranging the long mixing blade inside is also long. When the nozzle is long, it is difficult to position the nozzle with respect to the object to be ejected, which makes the coating work difficult. In addition, the amount of fluid that remains in the nozzle and is discarded after application is large, and the fluid is wasted. Further, since the nozzle is long, the total length of the fluid mixing discharger is also long, which makes the handling of the fluid mixing discharger inconvenient.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fluid mixing discharger having a short nozzle length by forming a mixture having a high mixing effect and a short length. To do. The present invention also aims to provide a fluid mixing and discharging how by the fluid mixing dispenser.

The fluid mixing discharger according to the present invention is
A storage container that stores two or more types of fluid,
A nozzle for discharging a mixed fluid of two or more kinds of fluids supplied from the storage container is provided.
A mixture for mixing two or more kinds of fluids supplied from the storage container is arranged in the nozzle.
The mixture includes a laminate in which a plurality of mixing elements are laminated, and a first plate and a second plate that are arranged so as to face each other with the laminate in between.
The mixing element has a plurality of through holes that serve as holes inside the laminate.
The second plate has an opening that communicates with at least one through hole in the mixing element.
In the mixture, the mixing element is arranged such that a part or all of the through holes are displaced from the through holes of the adjacent mixing elements so that they partially overlap each other, and the through holes of the adjacent mixing elements. The two or more kinds of fluids are communicated with each other in a flowable manner, and the mixing elements are arranged so as to be divided and merged in the stacking direction and the extending direction .
In the mixture, the partition wall between the through holes of the mixing element is formed in a curved shape curved to one side in the circumferential direction of the mixing element .

The fluid mixing and discharging method according to the present invention
A method of discharging a fluid by the fluid mixing discharger.
The process of storing two or more types of fluid in the storage container, and
A step of simultaneously supplying the two or more kinds of fluids from the storage container into the nozzle, and
A step of mixing the two or more kinds of fluids with the mixture in the nozzle, and
It has a step of discharging a mixed fluid in which the two or more kinds of fluids are mixed from the nozzle.
In the mixing step, the two or more kinds of fluids are mixed as a whole while being divided and merged in the stacking direction and the extending direction of the mixing elements by passing through the through holes of the adjacent mixing elements in the mixture. It is made to flow so as to rotate in the same direction in the circumferential direction of the element, or to rotate in one direction in the circumferential direction of the mixed element as a whole, and then to rotate in the opposite direction.

According to the fluid mixing discharger of the present invention, since the laminate in the mixture is a stack of a plurality of plate-shaped mixing elements, the length in the lamination direction is short, so that the entire mixture can be shortened. Since the mixture divides and merges the fluid in the stacking direction and the extending direction of the mixing elements, the fluid can be highly mixed even if the mixture is short. Therefore, even if the mixture is short, the effect of mixing the fluid is high, and the nozzle for arranging the mixture inside can be shortened. As a result, the nozzle can be easily positioned on the object to be discharged, and the coating operation can be easily performed. In addition, the amount of fluid that remains in the nozzle after use and is wasted can be reduced, and waste of fluid can be prevented. Further, since the fluid mixing discharger can be shortened, the fluid mixing discharger can be easily handled.

Further, according to the fluid mixing / discharging method of the present invention, a high mixing effect can be exhibited even if the length of the mixture is shortened .

Hereinafter, embodiments of the present invention will be described.
As shown in FIG. 1, in the fluid mixing / discharging device 1 of the embodiment, the two types of fluids A1 and A2 (hereinafter, "two types of fluids" and the "mixed fluids" described later are all designated by the reference numerals "A". A storage container 2 in which the storage container 2 is stored and a nozzle 3 connected to the storage container 2 to mix two types of fluids A and discharge the mixed fluid A are provided as a main configuration, and the others are not shown. However, an extrusion member such as a piston that simultaneously pushes out two types of fluids A in the storage container 2 toward the nozzle 3 side, a driving member such as a lever that drives the extrusion member forward and backward, and the like can be provided.

The storage container 2 is provided with two storage chambers 21 and 22 for separately partitioning and storing two types of fluids A. The two types of fluids A can be, for example, a main agent and a curing agent of a two-component curable adhesive (mixed fluid A), but are not limited to this. The volumes of the storage chambers 21 and 22 are set so as to have an appropriate mixing ratio of the two fluids A. A tubular outlet 23 is provided at the tip of the storage container 2 so that the fluid A is pushed out from the storage chambers 21 and 22. A screw groove 24 is formed on the outer peripheral surface of the outlet 23, and the base end portion 32 of the nozzle 3 is screwed and connected. The storage container 2 is not limited to storing two types of fluids A, and may store two or more types of fluids A in separate compartments. Further, the storage container 2 may be of a cartridge type that can be attached to and detached from the loading portion of the apparatus main body.

As shown in FIG. 2, the nozzle 3 is formed in a substantially cylindrical shape in which a tip portion 31 for discharging the fluid A to the outside is tapered and tapered, and a substantially cylindrical mixture 4 is disposed inside. There is. The outer diameter of the mixture 4 is formed to be substantially the same as the inner diameter of the cylindrical portion of the nozzle 3, and almost all the fluid A supplied into the nozzle 3 passes through the inside of the mixture 4. There is. A screw groove 33 is formed on the inner peripheral surface of the base end portion 32 of the nozzle 3, and the nozzle 3 is connected to the storage container 2 by being screwed with the screw groove 24 of the outlet 23 of the storage container 2. A valve body that prevents the fluid A from flowing back into the storage container 2 from the nozzle 3 side may be provided at the connecting portion between the storage container 2 and the nozzle 3.

The mixture 4 is housed in the nozzle 3. By inserting the mixture 4 into the nozzle 3 and connecting the nozzle 3 to the storage container 2 so that the mixture 4 does not fall, the mixture 4 can be dropped from the nozzle 3 by the outlet 23 of the storage container 2. Absent. The other end surface of the mixture 4 is arranged so as to abut on the tapered inner peripheral surface of the tip portion 31 of the nozzle 3, thereby preventing the mixture 4 from moving toward the tip portion 31 side of the nozzle 3. be able to. As shown in FIG. 3, a step portion 34 is provided on the inner peripheral surface of the nozzle 3 instead of the tapered inner peripheral surface of the tip portion 31, so that the mixture 4 moves toward the tip portion 31 side of the nozzle 3. You may block it. Further, the mixture 4 in the nozzle 3 may be fixed by a coil spring having a tapered side.

The mixture 4 includes a laminate 6 in which a plurality of substantially disk-shaped mixing elements 61 are laminated, and a substantially disk-shaped first plate 7 and a second plate 8 arranged to face each other with the laminate 6 interposed therebetween. To be equipped. The mixing element 61, the first plate 7 and the second plate 8 can be formed of metal or resin. Center holes 62, 71, 81 (see FIGS. 4 and 6) penetrating the plate thickness are provided at the center positions of the plurality of mixing elements 61, the first plate 7, and the second plate 8, respectively. By inserting the bolt 41 into the center holes 62, 71, 81 and tightening with the nut 42, the plurality of mixing elements 61, the first plate 7 and the second plate 8 are made of the bolt 41 and the nut 42 (fixing means). It is fixed in a laminated state so that it can be disassembled. As a result, the mixture 4 can be easily formed from the plurality of mixing elements 61, and cleaning work such as removal of the fluid A remaining after being decomposed from the mixture 4 into each mixing element 61 can be easily performed. Can be done.

The fixing positions of the bolts 41 and nuts 42 in the mixture 4 are not limited to the central position, but can be fixed at one or a plurality of arbitrary positions such as the outer peripheral position. Further, the mixture 4 or the laminate 6 may be formed by one member by a 3D printer device or the like.

As shown in FIG. 4, the laminated body 6 is configured by laminating two types of mixed elements 61a and 61b. The two types of mixing elements 61a and 61b have a plurality of through holes 63 penetrating in the thickness direction together with a center hole 62 for the bolt 41. The plurality of through holes 63 are provided along the extending surface extending in the extending direction of the substantially disk-shaped mixing element 61, and are formed to have the same size and shape in the same circumferential direction. The two types of mixing elements 61a and 61b have different arrangement patterns of the through holes 63, respectively. The laminated body 6 is formed by alternately laminating these two types of mixed elements 61a and 61b.

The mixing element 61 in the laminated body 6 is arranged so that a part or all of the through hole 63 partially overlaps with the through hole 63 of the adjacent mixing element 61 so as to be displaced from the position of the through hole 63, and the mixing element 61 of the adjacent mixing element 61. The fluid A is communicated with the through hole 63 so as to be able to flow, and the fluid A is arranged so as to be divided and merged in the stacking direction and the extending direction of the mixing element 61. In other words, the partition walls 64 of the through holes 63 arranged in the radial direction and the circumferential direction of the mixing element 61 are arranged at different positions between the adjacent mixing elements 61. As a result, the fluid A flowing through the inside of the mixture 4 sequentially flows between the through holes 63 of the adjacent mixing elements 61 inside the laminated body 6, as schematically shown in FIG. 5, thereby causing the mixing element 61 to flow. Will be divided and merged at the same time in each of the stacking direction and the extending direction, and will be highly mixed.

Further, in the through hole 63 of the mixing element 61 in the laminated body 6, the area of the overlapping portion 63a of one through hole 63 and the area of the other overlapping portion 63b adjacent to this portion are arranged non-uniformly in the circumferential direction. (See Fig. 4). As a result, the fluid A passing through the through hole 63 is divided and merged non-uniformly in the circumferential direction, and the mixing efficiency can be further improved. The area of the overlapping portion of the through holes 63 of the mixing element 61 in the laminated body 6 may be evenly arranged in the circumferential direction.

As shown in FIG. 6A, the first plate 7 is a disk having only a central hole 71 for the bolt 41 and no other holes. As shown in FIG. 6B, the second plate 8 has a central hole 81 for the bolt 41 and a substantially C-shaped opening 82 for passing the fluid A in the central portion. The outer diameter of the second plate 8 has substantially the same outer diameter as the mixing element 61, and the outer diameter of the first plate 7 is smaller than that of the second plate 8 and the mixing element 61. Therefore, in the mixture 4, the through hole 63 of the mixing element 61 is exposed on the outside of the outer peripheral portion of the first plate 7, and the through hole 63 of the mixing element 61 penetrates in the opening 82 of the central portion of the second plate 8. The hole 63 is exposed (see FIG. 2). That is, with respect to the mixture 4 in the nozzle 3, the fluid A flows in or out from the through hole 63 of the mixing element 61 exposed to the outside of the outer peripheral portion of the first plate 7, and flows in or out from the center of the second plate 8. It will flow in or out from the through hole 63 of the mixing element 61 exposed to the opening 82 of the portion.

As shown in FIG. 2, the mixture 4 arranged in the nozzle 3 is a set of a mixture in which the first plate 7 and the second plate 8 are arranged so as to face each other with the laminate 6 sandwiched in the stacking direction. Two sets of 4 can be connected in the stacking direction to form a configuration in which two sets of the mixture 4 are used. In the mixture 4 using the two sets, the second plate 8 is arranged in the middle of the lamination direction and shared, the laminate 6 is arranged on both side surfaces of the second plate 8, and the outside of each laminate 6. A configuration in which the first plate 7 is arranged on the end face and fixed in the stacking direction with bolts 41 and nuts 42 (first plate 7-laminated body 6-second plate 8-laminated body 6-first plate 7). ).

In such two sets of the mixture 4, the fluid A flows inside the mixture 4 in the nozzle 3 as follows. That is, with reference to FIG. 2, the fluid A sent from the storage container 2 first flows into the inside of the first set of laminated bodies 6 from the outside of the outer peripheral portion of one of the first plates 7 from the outer peripheral side. The fluid A that has flowed into the inside of the first set of laminated bodies 6 from the outer peripheral side flows through the inside of the first set of laminated bodies 6 while being divided and merged in the stacking direction and the extending direction, and is distributed in the center of the second plate 8. To the opening 82 of the portion. The fluid A that has flowed through the inside of the first set of laminates 6 and has flowed to the second plate 8 has passed through the opening 82 at the center of the second plate 8 and is on the center side inside the second set of laminates 6. Inflow from. The fluid A that has flowed into the inside of the second set of laminated bodies 6 from the central side flows through the inside of the second set of laminated bodies 6 while being divided and merged in the stacking direction and the extending direction, and the other first plate 7 To the outer periphery of. Then, the fluid that has flowed through the inside of the second set of laminated bodies 6 and has flowed to the other first plate 7 flows out from the outside of the outer peripheral portion of the other first plate 7 to the outside of the mixture 4. In this way, since the fluid A meanders through the inside of the two sets of the mixture 4 via the outer circumference → the center → the outer circumference, the fluid A can be mixed more highly.

The mixture 4 to be arranged in the nozzle 3 is not limited to the one using two sets of the mixture 4 as shown in FIG. 2, and one stacking is performed as needed, such as the type of the fluid A to be mixed. One set of the mixture 4 having the body 6 as a unit may be used, or the mixture 4 may be used in combination of three or more sets. For example, as shown in FIG. 7, the first plate 7 and the second plate 8 other than the first plate 7 arranged on both end faces are shared between the adjacent laminates 6, and the mixture 4 is 4 It is also possible to use a set. In this case, the fluid A repeats the meandering flow of the outer circumference → the center → the outer circumference twice inside the mixture 4, so that the fluid A is mixed more highly.

The method of assembling the fluid mixing discharger 1 having the above configuration includes a step of forming the mixture 4, a step of inserting the mixture 4 into the nozzle 3 and arranging the mixture 4, and a nozzle 3 in which the mixture 4 is arranged. It has a step of connecting to the outlet 23 of the storage container 2.

As described above, in the laminated body 6 of the mixture 4, two types of mixing elements 61a and 61b are superposed at predetermined positions in the circumferential direction, and in order to facilitate the superposition, the two types of mixing elements 61a and 61b are superposed. A notch 65 for specifying the superposition position of each mixing element 61 is formed on the outer edge portion (see FIG. 4). Then, in the step of forming the mixture 4, as shown in FIG. 8, a plate-shaped guide plate (guide member) 9 extending in the stacking direction of the laminated body 6 is provided in the notches 65 of all the mixing elements 61. The laminated body 6 is formed by aligning the notches 65 of each mixing element 61 in a row and superimposing them in the applied state. As a result, the two types of mixing elements 61a and 61b can be easily overlapped at predetermined positions in the circumferential direction, and the mixture 4 can be efficiently assembled. The mixing element 61 may be superposed with the two types of mixing elements 61a and 61b at predetermined positions in the circumferential direction without providing the notch 65 and without using the guide plate 9.

In the two sets of the mixture 4 shown in FIG. 2, the guide plates 9 used to align the mixing elements 61 of the laminated bodies 6 in each set at predetermined positions in the circumferential direction are arranged in the middle. A groove portion 91 for inserting the outer edge portion of the second plate 8 is used. For example, as a method of assembling the mixture 4 using two sets, as shown in FIG. 8, the bolt 41 of the fixing means has a first plate 7, a plurality of mixing elements 61, a second plate 8, and a plurality of mixing. The element 61 and the first plate 7 are inserted in this order, and the nut 42 is lightly tightened on the tip side of the bolt 41. Then, the outer edge portion of the second plate 8 is inserted into the groove portion 91 of the guide plate 9, and the notches 65 of all the mixing elements 61 are inserted into the guide plate 9, and the notches 65 of each mixing element 61 are inserted. Align in a row. After that, by firmly tightening the nut 42, the assembly of the mixture 4 using two sets is completed.

As described above, according to the fluid mixing discharger 1 according to the embodiment, since the laminated body 6 in the mixed body 4 is formed by laminating a plurality of plate-shaped mixing elements 61, the length of the laminated body 6 in the laminating direction. Can be formed short. Since the first plate 7 and the second plate 8 arranged on both end faces of the laminate 6 are also plate-like, the mixture 4 having such a laminate 6 as a main part is the mixing element 61. The length in the stacking direction can be shortened. Further, since the mixture 4 flows the fluid A so as to divide and merge in the stacking direction and the extending direction of the mixing element 61, the fluid A can be highly mixed even if the mixture 4 is short. For example, from the tip 31 of the nozzle 3, the two-component curable adhesive that becomes the mixed fluid A obtained by sufficiently mixing the main agent and the curing agent as the two types of fluids A has appropriate adhesive strength. It can be discharged. Therefore, even if the mixture 4 is short, the mixing effect of the fluid A is high, and the nozzle 3 in which the mixture 4 is arranged can be shortened. As a result, since the nozzle 3 is short, the nozzle 3 can be easily positioned on the object to be ejected, and the coating operation can be easily performed. In addition, the amount of fluid that remains in the nozzle 3 and is discarded after application can be reduced, and waste of the fluid A can be prevented. Further, since the fluid mixing discharger 1 can be made compact by reducing the length size, the fluid mixing discharger 1 can be easily handled and the storage space is not widened.

The two types of mixing elements 61 are not limited to the above-described forms, and for example, as in the mixing elements 61Xa and 61Xb shown in FIG. 9, the partition wall 64 extending in the radial direction between the through holes 63 is unidirectionally in the circumferential direction. It can have a curved curved shape, that is, an involute curved shape (involute type). As the involute type mixing element 61X, in addition to the one shown in FIG. 9, a partition wall 64 extending in the radial direction is continuous from the center to the outer circumference, and the partition wall 64 is curved in one direction in the circumferential direction. It also includes things to do. The two types of involute type mixing elements 61Xa and 61Xb also have different arrangement patterns of the through holes 63. In the laminated body 6, two types of involute type mixing elements 61Xa and 61Xb are alternately laminated, and in the mixed element 61X in the laminated body 6, part or all of the through holes 63 are through holes 63 of the adjacent mixing elements 61X. The fluid A is circulated so as to be partially overlapped with each other by shifting its position, and the fluid A can be circulated between the through hole 63 of the adjacent mixing element 61X, respectively, in the stacking direction and the extending direction of the mixing element 61X, respectively. It is arranged so that it can be divided and merged into.

In the mixture 4 using such an involute type mixing element 61X, as conceptually shown in FIG. 10, the fluid A inside the mixture 4 rotates in a spiral shape and flows, and the fluid A further flows. Can be highly mixed. Then, as the mixture 4 arranged in the nozzle 3, for example, as shown in FIGS. 2 and 7, when two or more sets of the involutate type mixture 4 are connected, the inside of the mixture 4 is used. The spiral rotation direction of the flowing fluid A is the same rotation direction (FIG. 10 (a)) in each set of the mixture 4, and the reverse rotation direction (FIG. 10 (b)) between the two adjacent mixture 4. )), In addition, the mixture 4 can be connected to a plurality of sets by setting the spiral rotation direction of the fluid A to an arbitrary combination. In the mixture 4 using the involute type mixing element 61X as described above, the flow of the fluid A in the mixture 4 can be further changed, and the fluid A can be mixed more highly.

The present invention is not limited to the above-described embodiment, and modifications can be made as appropriate within the scope of the gist of the present invention.
