【考案の詳細な説明】 産業上の利用分野 本考案は、二液型エポキシ樹脂塗料を塗装ガンに供給

給するようにした二液混合供給装置に関する。[Detailed Description of the Invention] Industrial Application The present invention, as in the case of supplying a two-pack type epoxy resin paint to a coating gun, pumps two kinds of liquids by separate gear pumps and mixes them by a mixer. The present invention relates to a two-liquid mixing and supplying device adapted to supply a single discharging device.
従来の技術及び考案が解決しようとする課題 二液型エポキシ樹脂塗料で塗装を行う場合の塗料供給
装置としては、例えば、実公平２−33898号公報に記載
されているように、主剤と硬化剤とを、共通の駆動モー

混合器で混合して塗装ガンに供給するようにしたものが

ち吐出量が所定の比率となるように設定していた。Problems to be Solved by the Related Art and Invention As a paint supply device for coating with a two-pack type epoxy resin paint, for example, as described in Japanese Utility Model Publication No. 2-33898, a main agent and a curing agent are used. And are separately pumped by two gear pumps driven by a common drive motor,
It is known that the mixture is mixed by a mixer and supplied to a coating gun. In order to determine the mixing ratio of the main agent and the curing agent, each gear pump is equipped with a transmission, and by adjusting each transmission, the rotation speed of each gear pump, that is, the discharge rate, is set to a predetermined ratio. Was there.
ところで、このように二液の混合比を設定する場合、
一方のギヤポンプの回転数を一定にし、他方のギヤポン
プの回転数のみを変えれば、両回転数の比に基づいて混
合比を自在に変えることができるのであつて、従来装置
のように各ギヤポンプに夫々変速器を装備する必要はな
く、変速器が２個あればかえつて設定作業に手間取り、
また、設備費も余分に掛かつて無駄となることに思い至
つた。By the way, when setting the mixing ratio of the two liquids in this way,
If the rotation speed of one gear pump is kept constant and only the rotation speed of the other gear pump is changed, the mixing ratio can be freely changed based on the ratio of both rotation speeds. It is not necessary to equip each with a gearbox, and if there are two gearboxes, it takes time to set up.
In addition, I realized that the equipment cost was too high and wasted.
課題を解決するための手段 本考案の二液混合供給装置は、上記の考察に基づいて
案出されたものであつて、各ギヤポンプの駆動源を共通
の可変速モータとし、そのモータと各ギヤポンプとを、
一方のギヤポンプ側にのみ変速器を介設して夫々駆動連
結した構成とした。Means for Solving the Problems The two-liquid mixing and feeding device of the present invention has been devised based on the above consideration, in which the drive source of each gear pump is a common variable speed motor, and the motor and each gear pump. And
A transmission is provided only on one gear pump side, and the transmissions are connected to each other.
考案の作用及び効果 可変速モータを起動すると、両ギヤポンプが駆動し
て、二種類の液体が各ギヤポンプの回転数に対応した一
定量ずつ圧送され、混合器により混合されて吐出装置に
供給される。この際、変速器によりその変速器を介設し
た側のギヤポンプの回転数を調整すると、それと、他方
のギヤポンプの回転数との比率に対応した二液の混合比
が得られる。また、可変速モータ自体の回転数を上げ下
げすることによつて、二液の混合比をそのままに混合液
の供給量が制御される。Action and effect of the invention When the variable speed motor is started, both gear pumps are driven, and two kinds of liquids are pumped by a fixed amount corresponding to the rotation speed of each gear pump, mixed by a mixer and supplied to the discharge device. . At this time, when the rotation speed of the gear pump on the side where the transmission is interposed is adjusted by the transmission, the mixing ratio of the two liquids corresponding to the ratio of the rotation speed of the gear pump to the rotation speed of the other gear pump is obtained. Further, by increasing or decreasing the rotation speed of the variable speed motor itself, the supply amount of the mixed liquid is controlled while keeping the mixing ratio of the two liquids unchanged.
すなわち、本考案によれば、二液の混合比を設定する
に当たつて１個の変速器のみを調整すれば良いから、設
定作業が簡単となり、また、変速器を１個としたことに
より、設備費低減を計ることができる効果がある。That is, according to the present invention, only one transmission needs to be adjusted to set the mixing ratio of the two liquids, which simplifies the setting work and also reduces the number of transmissions to one. There is an effect that the facility cost can be reduced.
実施例 以下、本考案を二液型エポキシ樹脂塗料の供給装置に
適用した一実施例を第１図に基づいて説明する。Embodiment An embodiment in which the present invention is applied to a two-pack type epoxy resin coating material supply device will be described below with reference to FIG.

ようになつている。主剤圧送路2a側のギヤポンプ3aは、
上記のエアモータ８と減速器11を介して駆動連結され、
エアモータ８の回転数を一定に減速した回転数で駆動さ

つている。The drive source of both gear pumps 3a, 3b is a variable speed air motor 8, and the number of revolutions can be controlled by adjusting the air supply amount from the air supply source 10 by the adjuster 9. There is. The gear pump 3a on the main agent pressure feeding path 2a side is
The air motor 8 and the speed reducer 11 are drivingly connected to each other,
The air motor 8 is driven at a rotational speed that is a constant deceleration of the rotational speed. On the other hand, the gear pump 3b on the side of the hardening agent pressure feed path 2b is drivingly connected to the air motor 8 via the transmission 12 so that the number of revolutions thereof can be continuously changed.
次に本実施例の作動を説明する。 Next, the operation of this embodiment will be described.
塗料供給に際しては、まず、主剤Ａと硬化剤Ｂの混合
比を設定するために、変速器12により硬化剤Ｂ側のギヤ
ポンプ3bの回転数を調整する。混合比が2:1の場合は、
その硬化剤Ｂ側のギヤポンプ3bの回転数を、主剤Ａ側の

々のギヤポンプ3a、3bの回転数に対応して2:1の流量で
吐出され、混合器５により混合されて塗装ガン６に供給
される。When supplying the coating material, first, the speed of the gear pump 3b on the curing agent B side is adjusted by the transmission 12 in order to set the mixing ratio of the main agent A and the curing agent B. If the mixing ratio is 2: 1,
The rotation speed of the gear pump 3b on the hardener B side may be adjusted to be half the rotation speed of the gear pump 3a on the main agent A side. Then, when the air motor 8 is started at a predetermined rotation speed, both gear pumps 3a and 3b are driven, and the main agent A and the hardening agent B are discharged at a flow rate of 2: 1 corresponding to the rotation speeds of the respective gear pumps 3a and 3b. It is mixed by the mixer 5 and supplied to the coating gun 6.
混合比を変える場合は、上記と同様に変速器12を調整

すれば、主剤Ａと硬化剤Ｂの混合比をそのままにして、
混合塗料全体の供給量が制御される。When changing the mixing ratio, the transmission 12 may be adjusted in the same manner as described above to vertically adjust the rotation speed of the gear pump 3b on the curing agent B side. Further, if the number of rotations of the air motor 8 itself is raised or lowered, the mixing ratio of the main agent A and the curing agent B remains unchanged,
The supply amount of the entire mixed paint is controlled.
