Description

Injector and infusion mixer nozzles for two-liquid mixed curable resins

The present invention relates to an injector and an infusion mixer nozzle of a two-liquid mixed curable resin such that the static mixer newly improves the joining means of the adapter or the mixer head and the two-liquid supply pipe and automatically replaces the static mixer.

Conventionally, a static mixer in which elements of a form in which a spiral element of a right turn and a sintered warp are connected to each other in a mixer pipe is connected to each other and used for various mixing purposes. Application development was also performed as a mixed extruder of resin which hardens and hardens | cures, or a resin injector.

Among the static mixers for two-liquid mixed curable resins, in which an injection nozzle is formed at the tip of the mixer pipe, the adapter b in which the two-liquid supply pipes a and a 'are connected and fixed as shown in FIG. For example, the injection mixer nozzle d which detachably connected the mixer pipe c was used.

As a detailed structure of the injection mixer nozzle d, a pair of receivers e and e 'are dug up on both sides of the adapter b for supplying two kinds of reagent liquids, and the fitting protrusion f is projected to form the lower side of the adapter b. At the same time, a partition plate g is integrally formed at the lower end of the fitting projection f, and a pair of discharge ports h and h 'are provided in the projecting direction of the fitting projection f so as to be open to both sides of the partition plate g. And dilute the large diameter holes of the receiving ports e and e 'and the small diameter holes of the discharge holes h and h'. It was supposed to communicate with each other by j and j '.

In the adapter b of this structure, the supply pipes a and a 'having screw threads l and l', such as PT screws, to the screw ports k and k 'at the receiving ports e and e' are connected with screws. At the same time, reagent liquid supply pipes n and n 'and washing liquid supply pipes o and o' are connected to three-way valves m and m 'provided in the supply pipes a and a'.

In addition, the fitting projection f of the adapter b is fitted with a pipe casing q installed on the upper end of the mixer pipe c in which the element p is internally fixed, and tightly fixed by means of connection or screw connection. The connecting member r is formed integrally with the lower part of the adapter b around the fitting protrusion f, and the pipe casing q is inserted into the vertical groove provided in this connecting member r, and it rotates in the horizontal groove, and the mixer pipe is connected to the adapter b. c is fixed.

As a normal use method, two-way valves m and m 'are operated to feed two types of reagent liquids from the reagent liquid supply pipes n and n' to the receiving ports e and e ', and the horizontal flow path holes i and i' and It discharges from the discharge ports h and h 'provided in the front end surface s of the fitting protrusion f via the longitudinal flow holes j and j', and the two reagents are joined at the proximal end of the mixer pipe c, which is the tip position of the partition plate g, As the pumping of the reagent liquid by the reagent liquid supply pipes n and n 'continues, the combined reagent liquid passes through the element p in a complicated manner and flows through the mixer pipe c toward the tip.

When the reagent solution passes through the element p, the mixing of the two reagents proceeds by the action of ① flow splitting, ② flow inversion, and ③ radial mixing, which is the action of the element p of the static mixer. The reaction is initiated and curing is started. The cured resin is extruded from the tip of the injection mixer nozzle d, injected into a molding machine, etc. in a container, and a series of supply of curable resin is performed.

After the filling operation of the curable resin is completed, when the injection mixer nozzle d is left, the reagent liquid around the mixer pipe c and the partition plate g is completely solidified, and the supply pipes a and a 'are firmly fixed to the adapter b. Therefore, the pipe casing q of the mixer pipe c is removed from the fitting projection f, which is a relatively easy place, and the three-way valves m and m 'are operated to discharge the cleaning liquid from the discharge ports h and h' to fit the fitting projection f and the partition. Cleaning plate g and so on.

As a result, the removal work from the adapter b of the mixer pipe c, the cleaning work of the fitting protrusion f, etc. are required, and the reagent liquid from the transverse flow holes i, i 'and the vertical flow holes j, j', etc. Leakage or the outflow of the cleaning liquid had the disadvantage of worsening the working environment such as the floor surface.

In the cleaning operation of the injection mixer nozzle d, when the cleaning liquid is supplied to the mixer pipe c, and the mixer pipe c and the element p are cleaned and reused, the drawbacks of the above cleaning operation and deterioration of the working environment increase.

In addition, as mentioned above, the flow path into which the two kinds of reagent liquids flow into the mixer pipe c includes the receiving ports e and e ', the horizontal flow path holes i and j', the vertical flow path holes j and j 'which are dug into the adapter b. In the order of the outlets h and h ', and the pipe casing q of the mixer pipe c is fitted into the fitting projection f formed by digging the vertical flow holes j and j', and the flow path diameter of the mixer pipe c Iii) is determined by its use, the outer diameter of the fitting protrusion f of the connecting structure is also determined accordingly, and thus the vertical flow path j, which is a flow path of two reagent liquids dug and installed in the fitting protrusion f, j 'also has a structure in which the flow path diameter is limited accordingly.

In addition, as a function of the static mixer, in addition to the three operations relating to the basic mixing described above, as a fourth operation, the velocity distribution does not occur in the axial direction due to the division, inversion, and switching of the continuous flow. The change is small, that is, there is almost no backmixing and close to the piston flow, and in order for the static mixer to fully exhibit the mixing performance, accurate supply of the two reagents is essential. The selection of the metering pump and the injection situation of the reagent liquid are related.

With respect to such quantitative supply, the amount of the two kinds of reagent liquids is different depending on the various curable resins, and even if the backflow is small, it is essential to supply quantitatively at the same pressure at the inlet to the mixer pipe c.

However, since the pair of longitudinal flow paths j and j 'formed by digging into the fitting protrusion f have the same diameter, the flow velocity and pressure of the reagent liquid supplied from the metering pump and passing through the vertical flow paths j and j' must be changed. As described above, since the diameter of the vertical flow path j, j 'is limited, there is a drawback that the pressure must be increased in the reagent liquid having a large flow rate.

In addition, with respect to the supply flow path system of the reagent liquid including the metering pump for metering supply, pressure fluctuations due to pulsation are incidentally occurring in the supply flow path of the pressure fluid, so that the flow path diameter can be changed with respect to the pressure change of the fluid If it is not, or if the diameter is small, it is difficult to cope with the pressure fluctuation, the securing of the fixed flow rate of the two reagents supplied to the mixer pipe c is broken, and the curing by the chemical reaction is not sufficient, or the desired resin is removed. There was a flaw that could not be obtained.

Next, when the injector having the injection mixer nozzle d is connected to the molding machine, in the mixer pipe c, since curing by two-liquid mixing occurs, for example, the curable resin adheres to the inside of the mixer pipe c. When the function is deteriorated, the adapter b connected to the above-described supply pipes a and a 'is intended to prevent fouling of the molding machine and the like, and the detachment work of the mixer pipe c and the cleaning work time of the adapter b are performed. Since this is necessary, there existed a fault that the downtime of a molding machine etc. becomes long.

It is an object of the present invention to provide an injector and an injection mixer nozzle of a two-liquid mixed curable resin made to facilitate post-treatment such as washing after the completion of an injection operation without the problems of the prior art.

SUMMARY OF THE INVENTION In view of the problem of the present invention, in view of the problem of fixing the supply pipe of the two reagent solutions based on the above-described conventional technique and requiring the washing of the adapter with the mixed reagent solution, the two types of reagent solutions are applied to the mixer head of the static mixer. By freely attaching and detaching the mixing head which connected the supply pipe, it becomes possible to disconnect and leave the flow path at the portion where the reagent liquid is still unmixed.

In addition, in view of the problem of deterioration of the working environment due to the drop of the reagent liquid during washing, a sag bag valve is provided in the supply passage of the reagent liquid so that the reagent liquid is sucked at the time of blocking the flow path. It is to solve the problem.

In addition, a pressure fluid pressure detection sensor 118, 118a is installed in the connecting pipes 71, 71a connecting the supply valves 5, 5a and the flow paths 23, 23a, and the operation of the pressure detection sensors 118, 118a is performed. 80, exchange arm 85, etc. are to be operated.

Next, the operation of the injector of the two-liquid mixed curable resin for automatically replacing the injection mixer nozzle according to the present invention will be described.

By operating the air chuck 90, the mixer heads 41 and 3a of the static mixers 3 and 3a are pressed together with the mixing heads 15 and 15a installed in the channel forming bodies 19 and 19a. The pressure in the connection pipes 71 and 17a for discharging the curable resin from the discharge nozzle portions 43 of the static mixers 3, 3a ... and supplying the two reagent liquids by the start of curing in a predetermined state in the mixer pipe 40 also becomes a predetermined range. .

However, if the curable resin adheres to the mixer pipe 40 and the resistance increases by continuously supplying the curable resin to the molding machine or the like, the pressure of the two reagents in the connection pipes 71 and 71a also increases, and the exchange setting pressure is exceeded. The static mixers 3, 3a ... set in the injector 80 are started by detecting the current state of the pressure detection sensors 118, 118a.

Thus, when the static mixers 3, 3a ... are held in the upper portion of the guide cylinder body 101, the exchange arm 85 which is not maintained is moved in the direction of the injector 80 following the operation of the cylinder 112. The exchange box 85, which has passed through the lower part of the guide body 101, holds the static mixers 3, 3a ... of the injector 80 and retains the static mixers 3, 3a ... to be replaced at the end of use.

Then, by disassembling the air chuck 90 in the injector 80, the mixing heads 15 and 15a of the flow path forming bodies 19 and 19a are separated from the mixer head 41 of the static mixers 3 and 3a. The lower surface 41e of the finished static mixer 3, 3a ... is supported only by the exchange arm 85, and the static mixer 3, 3a ... is released from the injector 80 by the retraction of the exchange arm 85, and the retraction of the exchange arm 85 continues. As a result, the mixer head 41 of the static mixers 3, 3a ... collides with the lower end of the guide cylinder body 101 and falls off from the arm members 116, 116a.

Next, the exchange arm 85 continues to retract and returns to its original position, and when the cylinder 106 above the guide body 101 is retracted, the static mixers 3, 3a ... on the upper side of the guide body 101 descend and are held by the exchange arm 85. The static mixers 3, 3a ... disposed on the base of the supply base are inclined and the lowermost static mixers 3, 3a ... fall above the inside of the guide body 101, and the operation of the cylinders 106 causes the static mixers in this position. 3, 3a ... are held by the support arm 108 above the guide body 101.

In addition, although the pressure in the connecting pipes 71 and 71a supplying the two reagent liquids was detected as the determination means at the time of replacing the static mixers 3, 3a ... which have been used, the number of discharges of the curable resin was used as the determination means. It is okay.
