Description

  The present invention relates to a simultaneous discharge device for a two-component reaction liquid such as a two-component adhesive and a two-component foaming composition.

  Conventionally, two-component (two-component) reaction solutions such as two-component adhesives and two-component foamed compositions need to be stored in separate containers so that no reaction occurs before use. . For this reason, for example, two-component adhesives for personal users are generally marketed in the form of two tubes each containing two solutions. Therefore, the user needs to squeeze each liquid from the two tubes onto the substrate and use it at the time of use, so that the application work is extremely troublesome and the hands and clothes are easily stained. There was a problem.

  In order to solve the above problems, for example, in the case of mixed application of a two-component adhesive, each solution of the adhesive is distributed and stored in a double cartridge or tube, and at the time of use, two devices are used by using an extrusion device. Devices for extruding and discharging liquids have been developed. For example, in Japanese Utility Model Publication No. 62-298473 (Patent Document 1), a movable body is moved by a lever operation for reciprocating a movable rod, and a bottom plate of a loaded container is pushed or a container is crushed. A two-liquid discharge device is disclosed in which contents are discharged simultaneously from a container. Japanese Utility Model Laid-Open No. 2-138183 (Patent Document 1) has flexibility that is obtained by separately filling two liquids to be cured by mixing on the inlet side of a nozzle provided with a mixer for mixing two liquids. The opening portions of the two bag-like tubes are arranged side by side and connected to each other, and the two bag-like tubes are opposed to each other by the rotation of the screw rods, so that the gap can be reduced between a pair of holding plates. There is disclosed a gap filling tool that compresses a bag-like tube and discharges two liquids of a two-part adhesive by narrowing and rotating a screw rod to narrow the gap between the pair of pressing plates.

  However, when discharging two liquids of a two-component adhesive using an extrusion apparatus as described above, the container containing the contents and the protective cap of the bag-like tube are removed and attached to the apparatus main body at the time of use. This is troublesome and has operability problems, and there is a risk of causing liquid leakage when worn and soiling hands and clothes. In addition, since the operation direction for operating the movable body or rotating the screw rod for narrowing the interval between the pressing plates is different from the discharge direction of the contents, there is a problem that the operation of applying to the application surface is not successful.

  On the other hand, as a discharge system for a two-pack type foamable urethane composition, for example, in Japanese Patent Laid-Open No. 11-348138 (Patent Document 3), a first pump fed from the first and second tanks by the pressure of nitrogen gas is disclosed. And a second pumping urethane composition formed by mixing and mixing the first and second raw materials discharged from the cylinder pump that converts the raw material and the second raw material into a constant flow rate, respectively. Discloses a two-pack foaming urethane composition filling device including a mixing head that discharges water and two hydraulic pumps and a hydraulic unit that hydraulically drives the mixing head. However, such a device is a large-sized and high-cost device, and has been developed to automatically fill a closed cross-section of a vehicle body with a foam material in mass production such as an automobile production process.

The present invention provides a simultaneous discharge device for a two-component reaction liquid by a new method in order to solve the above-described problems of the prior art. In order to discharge the two liquids of the two liquid reaction liquids A and B at the same time,
A cylindrical main body having two cylindrical guide bodies each having a discharge end portion having a cleavable closed end face at the tip portion and preferably covered with a protective cap; Two pistons that are slidably inserted in a state that can be simultaneously operated from the rear end side, and the liquid A is accommodated in one of the two cylindrical guide bodies, An injection device in which the B liquid is contained in one;
A tubular connecting member whose rear end is connected to the distal end of the tubular body;
It has two needle-like connecting pipes whose rear end portions are formed at an acute angle, and the sharp end portions of the needle-like connecting pipes are oriented toward the closed end face (protective cap) side of each cylindrical guide body. It is necessary to provide a connecting member disposed in the cylindrical connecting member.
Further, in the two-component reaction solution simultaneous discharge device for injecting or filling the two-component reaction solution, two flow paths connected to the respective tip portions of the two needle-like connection tubes of the connecting member And a discharge pipe having a connecting portion connected to the cylindrical connecting member at the rear end portion.

  According to such a two-component type reaction liquid simultaneous discharge device of the present invention, two pistons, which are slidably inserted from the rear end side into the two cylindrical guide bodies, are simultaneously operated and pushed. Accordingly, the liquid A accommodated in one of the two cylindrical guide bodies and the liquid B accommodated in the other one can be simultaneously discharged through the discharge pipe. Therefore, the liquid A and the liquid B of the two-component reaction liquid can be discharged simultaneously easily and reliably with good workability. For example, when a two-component foamable urethane composition is used as a two-component reaction solution, the isocyanate and polyol injected into the gaps and recesses react immediately to foam, and countless fine bubbles, preferably from open cells It forms a urethane foam that fills the gaps and fine portions of the uneven surface in the recesses without gaps, adheres to the wall surface and hardens immediately, and becomes a rigid urethane foam that completely seals the gaps and recesses. it can.

  In order to reliably prevent liquid leakage from the two cylindrical guide bodies in which the two liquid reaction liquids A and B are respectively stored during storage, the discharge cylinder portion of the cylindrical guide body is used before use. It is preferable to keep the opening in a sealed state and allow the discharge pipe to communicate with the cylindrical guide during use. Therefore, the tip of each of the two cylindrical guide bodies into which the pistons are slidably inserted in a state where the pistons can be operated simultaneously from the rear end side is made to be an easily breakable closed end surface, preferably on the tip discharge cylinder portion. The connecting member provided in the cylindrical connecting member to which the discharge pipe is connected is provided with an acute angle at the rear end while being disposed in the cylindrical main body in a state of being covered with an easily breakable protective cap. Two needle-shaped connecting pipes, and the sharp end portions of the needle-shaped connecting pipes are oriented toward the closed end face (protective cap) side of the cylindrical guide bodies. Arrange. By adopting such a configuration, at the start of use, the connection member connected to the discharge pipe is connected to the distal end portion of the cylindrical main body via the cylindrical connection member. The sharp ends of the two needle-like connecting pipes penetrate the closed end surfaces (protection caps of the discharge cylinder parts) of the respective cylindrical guide bodies, and the two flow paths of the discharge pipes connected to the needle-like connecting pipes It will be in a communication state with each cylindrical guide body. As a form of the protective cap, a form covered with a peelable seal sheet, a form in which the discharge cylinder part of the cylindrical guide body is covered with a thin plastic film and bonded by adhesion, heat shrinkage, etc., or a soft shape previously formed into a cap shape A form in which a protective cap made of plastic is fitted or joined is possible, but from the viewpoint of the workability of filling A liquid or B liquid, the workability of attaching the protective cap, etc. The form to join is preferable.

  The discharge pipe has two flow paths connected to the respective tip ends of the two needle-like connection pipes of the connection member, and has a connection portion connected to the cylindrical connecting member at the rear end. There is no limitation to a specific form. For example, two flow paths are integrally formed inside the discharge pipe, and a tubular portion connected to each tip of the two needle-like connection pipes of the connecting member protrudes from the two flow paths. Moreover, the discharge pipe of the form which has two tubes which comprise two flow paths in the inside may be sufficient. Among them, the discharge pipe having the two flow paths is easy to manufacture, the manufacturing cost can be reduced, and from the viewpoint of the connection operability to the respective tip portions of the two needle-like connection pipes, 2 A discharge pipe having two tubes constituting one flow path is preferable.

  In addition, the two liquid reaction liquids A and B may be discharged simultaneously from the ends of the two flow paths, but in order to cure and foam quickly after injection, the two liquid reaction liquid A And B liquid are preferably discharged while being stirred and mixed. For this purpose, it is preferable to have a structure in which the liquid A and the liquid B pushed out through the two flow paths merge at one discharge flow path of the nozzle member. As such a structure, the distal end portion of the discharge pipe is formed with a connection tubular portion to which the distal ends of the two tubes or flow passages are connected, and one discharge flow passage communicating with the connection tubular portion. A form in which the nozzle member is inserted is preferable.

  Moreover, it is preferable that the discharge port portion of the processing apparatus has a structure in which the A liquid and the B liquid are stirred and mixed. As such an agitation / mixing mechanism, it is preferable that the baffle plate portion, preferably at least a pair of baffle plate portions be opposed to each other on the inner surface of the discharge passage of the nozzle portion. It is possible to adopt a configuration that projects at an angle of. In addition, a spiral baffle plate portion may be formed on the inner surface of the discharge flow channel of the nozzle portion to generate a vortex. By providing such a stirring / mixing mechanism in the discharge flow path of the nozzle portion, the liquid A and the liquid B are mixed in the discharge flow path, and the mixed two-component reaction liquid is discharged. Therefore, the reaction between the liquid A and the liquid B of the two-component reaction liquid occurs quickly, and curing and foaming can be caused quickly.

  In addition, the discharge pipe may have a flexible or flexible straight tubular shape or a curved portion formed in a curved shape from the tip so as to be inserted into a non-linear gap or recess. It can be set as any form of having. By setting it as such a form, a discharge pipe can be easily inserted also into a non-linear gap and a recessed part, and a 2 liquid type reaction liquid can be rapidly inject | poured and filled. Furthermore, without requiring skill in inserting the discharge pipe, the discharge port portion is always located at a fixed application site so that the two-component reaction liquid can be injected and filled. A stop mark, a color display, or the like can be added, and a stopper portion protruding outward in the radial direction can be provided at or near the connection portion of the discharge pipe. By providing such a stopper portion, it can be inserted so that the discharge port portion is surely positioned at a constant application site.

  As described above, in order to discharge the two liquids of the two liquid reaction liquids A and B at the same time, they are slidably inserted into the two cylindrical guide bodies of the injection device from the rear end side. Each piston needs to be engaged so that it can operate simultaneously. This engagement state may employ any configuration that can be appropriately selected by those skilled in the art, but preferably, a pressing portion extended in the lateral direction is formed at the rear end of each piston. Means for engaging with the other opposed pistons are provided at the base of each part, and preferably, the engaging pieces projecting so as to extend below the pressing portions of the other opposed pistons, Holes into which the pieces are inserted are respectively formed. With such a configuration, even if one of the pressing portions is pressed, the other pressing portion that is engaged is also pressed, so that the two pistons are pressed simultaneously. That is, with such a simple structure, it is possible to realize a state in which the pistons slidably inserted into the two cylindrical guide bodies can be engaged and operated at the same time. The A and B liquids of the reaction liquid can be discharged easily and reliably simultaneously with good workability.

In another preferred embodiment, the cylindrical main body has a pair of hooks for hooking fingers protruding outward in the radial direction at or near the rear end thereof. By providing such a buttock, a finger can be hooked on this, so that the extrusion operation is facilitated.
Further, the two cylindrical guide bodies of the injection device need to be fixed so as not to move into the cylindrical main body. This can be realized by various conventionally known fixing methods such as screwing and bonding, but preferably, a substantially annular recess is formed in the inner peripheral portion of the rear end portion of the cylindrical body, It can be realized by a simple structure in which a flange portion to be inserted into the concave portion is formed at the rear end portion of the cylindrical guide body of the injector, and the flange portion is fitted into the concave portion.

By appropriately setting the thickness and length of the discharge pipe described above, it can also be used as an apparatus for injecting and filling a two-component reaction liquid into gaps and recesses of various depths and sizes.
Furthermore, since the injection device of the present invention has a special structure called a double injector, there is little risk of being mistaken for a general syringe, but only the cylindrical body of the injection device is colored or its color is different from the color of other members. By coloring in this way and making it a colorful injection device, it can be easily discriminated without making a mistake with a general syringe, or the application location can be clearly grasped.
