Description

本考案は、注型、成形、塗装等において２種類の微量の薬液を混合して吐出する微量用二液混合型注入機に関する。   The present invention relates to a two-component mixing injector for a minute amount that mixes and discharges two kinds of minute amounts of chemicals in casting, molding, painting, and the like.

従来、本願出願人は、注入機の基体にスタティックミキサの装着部を設け、ミキシングヘッドを有する一対の流路形成体を基体に移動自在に装着し、又装着部にミキシングヘッドを進退させる進退機構部を設け、基体に進退自在に装着した一対の流路形成体は装着部に対向状態で装着し、ミキシングヘッドは先端縮径のテーパー状と成した２液混合硬化性樹脂の注入機を複数開発し出願しており（例えば、特許文献１参照）、この出願のものは、注入作業終了後における洗浄等の後処理を容易化することを主目的としたものである。   Conventionally, the applicant of the present application has provided a mounting portion for a static mixer on a base body of an injector, a pair of flow path forming bodies having a mixing head movably mounted on the base body, and an advancing / retracting mechanism for moving the mixing head back and forth in the mounting section A pair of flow path forming bodies mounted on the base body so as to be able to move forward and backward are mounted facing the mounting section, and the mixing head is provided with a plurality of two-component mixed curable resin injecting machines each having a tapered diameter at the tip. The application has been developed and applied (see, for example, Patent Document 1). The main object of this application is to facilitate post-processing such as cleaning after the completion of the injection operation.

特許第２７５０６６４号公報Japanese Patent No. 2750664

しかし、上記従来技術にあっては、往復移動するのはミキシングヘッドを有する流路形成体だけで、該流路形成体より上流側は往復移動せず、具体的には、特許文献１の〔００３７〕及び図１〜３に示されている通り、注入機の供給バルブと流路形成体に設けた薬液供給口である取付部とを、接続パイプで連通接続し、又一対の供給バルブの夫々には薬液供給パイプと、定量供給機能を有するギヤポンプ、プランジャーポンプ、ダイヤフラムポンプ等の圧送ポンプを設けた供給バルブを開閉作動する圧縮空気供給パイプを夫々接続し、供給バルブの圧送ポンプで薬液を接続パイプへ送出する様に成っており、２種類の薬液は、薬液容器から薬液供給パイプ、供給バルブ、接続パイプを経て流路形成体を通過し、ミキシングヘッドからスタティックミキサ内に供給されることになる。   However, in the above-described prior art, only the flow path forming body having the mixing head moves reciprocally, and the upstream side of the flow path forming body does not reciprocate. [0037] As shown in Figs. 1 to 3, the supply valve of the injector and the mounting portion which is the chemical solution supply port provided in the flow path forming body are connected in communication by a connection pipe, and the pair of supply valves Each of them is connected to a chemical supply pipe and a compressed air supply pipe that opens and closes a supply valve provided with a pressure feed pump such as a gear pump, a plunger pump, or a diaphragm pump having a fixed quantity supply function. The two types of chemical solutions pass from the chemical solution container through the chemical solution supply pipe, supply valve, and connection pipe, through the flow path forming body, and from the mixing head to the static tube. It is supplied to the inside Kumikisa.

つまり、特許文献１のものは、流路形成体は可動状態であるのに対し、供給バルブは固定状態であるため、可撓性を有する接続パイプが必要で、而も流路全体が長くなってしまって、通過時の圧力損失が大きくなり、その結果供給量に極僅かであるが誤差が生じ易く、よって微量の薬液を混合し吐出させることを目的とした二液混合型注入機としては不向きであるなど、解決せねばならない課題があった。   That is, in Patent Document 1, the flow path forming body is in a movable state, while the supply valve is in a fixed state, so a flexible connection pipe is required, and the entire flow path becomes longer. As a result, the pressure loss at the time of passage increases, and as a result, the supply amount is negligible but an error is likely to occur. Therefore, as a two-component mixing type injector for mixing and discharging a small amount of chemical solution, There were issues that had to be solved, such as being unsuitable.

本考案は、上記従来技術に基づく、２種類の薬液の流路の途中に可撓性を有するパイプが使用され、且つ流路全体が長い二液混合型注入機は、微量混合・注入用として使用し難い課題に鑑み、一対の縦型スクリューポンプの先端をヘッド部の上面に開口形成した挿入孔に挿設し、前記一対の縦型スクリューポンプの側部に供給路を開口形成し、該供給路に連通する送給路が穿設された一対の取付腕杆の基端部を前記一対の縦型スクリューポンプの側面に固設し、前記一対の取付腕杆の先端上面に、前記送給路に連通する取付孔を穿設し、該取付孔に２種類の薬液が別々に充填された一対の薬液容器を着脱可能に装着し、前記ヘッド部の下部にミキシングノズルを着脱可能に装着し、前記ヘッド部に、前記一対の縦型スクリューポンプからの薬液を前記ミキシングノズル内に送る流路を穿設し、薬液容器内の薬液が取付腕杆内の直線状の送給路を通って縦型スクリューポンプ内に供給され、該縦型スクリューポンプよりヘッド部内の流路を通ってミキシングノズル内に供給されることで、可撓性を有するパイプの無い短めの直線的な、圧力損失の無い流路が形成されることによって、微量混合・注入用として使用可能にして、上記課題を解決する。   The present invention is based on the above-mentioned prior art, and a two-liquid mixing type injection machine in which a flexible pipe is used in the middle of two kinds of chemical liquid flow paths and the entire flow path is long is used for mixing and injection of trace amounts. In view of problems that are difficult to use, the distal ends of a pair of vertical screw pumps are inserted into insertion holes formed in the upper surface of the head portion, and supply paths are formed in the side portions of the pair of vertical screw pumps. A base end portion of a pair of mounting arm rods provided with a feeding path communicating with the supply channel is fixed to a side surface of the pair of vertical screw pumps, and the feeding end is disposed on the top end surface of the pair of mounting arm rods. A mounting hole communicating with the supply path is drilled, and a pair of chemical liquid containers filled with two types of chemical liquids are detachably mounted in the mounting hole, and a mixing nozzle is detachably mounted at the lower part of the head portion. The medicine from the pair of vertical screw pumps is applied to the head portion. Is formed in the mixing nozzle, and the chemical solution in the chemical solution container is supplied into the vertical screw pump through the linear supply path in the mounting arm, and the head is supplied from the vertical screw pump. By feeding into the mixing nozzle through the internal flow path, a short linear pressure-free flow path without flexible pipes is formed. It can be used to solve the above problems.

要するに本考案は、一対の縦型スクリューポンプの先端をヘッド部の上面に開口形成した挿入孔に挿設し、前記一対の縦型スクリューポンプの側部に供給路を開口形成し、該供給路に連通する送給路が穿設された一対の取付腕杆の基端部を前記一対の縦型スクリューポンプの側面に固設し、前記一対の取付腕杆の先端上面に、前記送給路に連通する取付孔を穿設し、該取付孔に２種類の薬液が別々に充填された一対の薬液容器を着脱可能に装着し、前記ヘッド部の下部にミキシングノズルを着脱可能に装着し、前記ヘッド部に、前記一対の縦型スクリューポンプからの薬液を前記ミキシングノズル内に送る流路を穿設しているので、可撓性を有するパイプは不要で、薬液の流路は取付腕杆に穿たれた送給路と、ヘッド部に穿たれた流路に限られるために短くすることが出来、よって圧力損失が殆ど無い薬液の流路を形成することが出来、従って微量混合・注入用として使用することが出来る。
更に、前記一対の縦型スクリューポンプを正逆回転駆動可能にすれば、１回の供給が終了した時点で逆回転させて、ローターとステーター間のキャビティ内に薬液が完全に存在しない状態にすることが出来るため、バルブを使用せずに１回毎の供給量の正確性をより向上させることが出来る等その実用的効果甚だ大である。 In short, the present invention inserts the distal ends of a pair of vertical screw pumps into an insertion hole formed in the upper surface of the head portion, and forms a supply passage in the side portion of the pair of vertical screw pumps. A base end portion of a pair of mounting arm rods having a feeding path communicating with the fixing arm is fixed to a side surface of the pair of vertical screw pumps, and the feeding path is disposed on the top end surfaces of the pair of mounting arm rods. A mounting hole communicating with the mounting hole, a pair of chemical liquid containers separately filled with two types of chemical liquids are detachably mounted, and a mixing nozzle is detachably mounted at the lower part of the head part, Since the flow path for sending the chemical solution from the pair of vertical screw pumps into the mixing nozzle is drilled in the head portion, a flexible pipe is not necessary, and the chemical solution flow path is a mounting arm. Limited to the feed path perforated in the head and the flow path perforated in the head It can be shortened in order, thus it is possible to form a flow path of little chemical pressure loss, hence can be used for the trace mixing and injection.
Further, if the pair of vertical screw pumps can be driven forward and reverse, they are rotated reversely when one supply is completed, so that the chemical solution does not completely exist in the cavity between the rotor and the stator. Therefore, it is possible to improve the accuracy of the supply amount for each time without using a valve.

その際に、薬液Ａ、Ｂは、薬液容器２、2aから取付腕杆８、8aの送給路７、7a、縦型スクリューポンプ４、4aの供給路６、6aを通過して縦型スクリューポンプ４、4a内に供給され、該縦型スクリューポンプ４、4aより所定量の薬液Ａ、Ｂが、ヘッド部５の流路12、12a を経てミキシングノズル３内に供給されるため、流路通過中に圧力損失が殆ど無い。
尚、縦型スクリューポンプ４、4aは、１回の供給が終了した時点で逆回転させて、ローターとステーター間のキャビティ内に薬液が完全に存在しない状態にすることで、バルブを使用せずに所定量を正確に供給することを可能にしている。 At that time, the chemicals A and B pass from the chemical solution containers 2 and 2a through the supply paths 7 and 7a of the mounting arm rods 8 and 8a, and the supply paths 6 and 6a of the vertical screw pumps 4 and 4a. Since a predetermined amount of chemicals A and B are supplied from the vertical screw pumps 4 and 4a to the mixing nozzle 3 through the flow channels 12 and 12a of the head unit 5, the flow channels are supplied to the pumps 4 and 4a. There is almost no pressure loss during the passage.
The vertical screw pumps 4 and 4a are rotated backward when one supply is completed, so that no chemicals exist in the cavity between the rotor and the stator, so that no valve is used. It is possible to accurately supply a predetermined amount.

又、ヘッド部５を装着部15、上部流路形成体16及び下部流路形成体17で構成し、上部流路形成体16に孔23、23a 及び溝24、24a を、下部流路形成体17に溝26、26a 及び孔27、27a を形成することで、ヘッド部５に流路12、12a が形成されるため、該流路12、12a を一直線形状にしなくても、簡単に直線形状を組み合わせた屈曲形状にすることが可能になる。   The head portion 5 is composed of a mounting portion 15, an upper flow path forming body 16 and a lower flow path forming body 17, and the upper flow path forming body 16 is provided with holes 23, 23a and grooves 24, 24a. By forming the grooves 26 and 26a and the holes 27 and 27a in the 17, the flow passages 12 and 12a are formed in the head portion 5. Therefore, even if the flow passages 12 and 12a are not straight, It becomes possible to make a bent shape in combination.
