【0014】上記構成からなる粉体染料の自動投入システムにおける粉体溶解装置の動作を以下に説明する。 [0014] illustrating the operation of the powder dissolving device in an automatic dosing system for the powder dyes having the above structure below.

【0015】まず、コンピュータ(15)におけるデータ入力により、自動計量装置(5)で計量すべき粉体量に基づく指令信号〔目標粉体量〕をディスペンサバルブ(3)の駆動部(10)に指令し、その駆動部(10)によりリードスクリュー(4)を回転させて貯蔵ホッパ(2) [0015] First, the data input in the computer (15), the driving unit of the automatic weighing device (5) dispenser a command signal based on the amount of powder to be metered [target amount of powder] In the valve (3) (10) command, and storage hopper by rotating a lead screw (4) by a driving unit (10) (2)
から所定量の粉体染料(1)を排出する。 Discharging a predetermined amount of the powder dye (1) from. このディスペンサバルブ(3)から押し出された粉体染料(1)をバケット(7)内に落とし込んで収容した上で、そのバケット(7)ごと粉体染料(1)をスケール(8)で計量する。 This powder dye extruded from the dispenser valve (3) (1) on which accommodates plunge into the bucket (7), metering the bucket (7) for each powder dye (1) a scale (8) .

【0016】この時、例えば、ディスペンサバルブ(3)を通過し得る大きさの塊状の粉体染料が排出されて、粉体染料(1)の排出量、即ち、バケット(7)に収容された粉体量が増加したとしても、その粉体量をスケール(8)で計量することにより、自動計量装置(5)により得られた実際の粉体量が判明する。 [0016] At this time, for example, powder dyes in the size of bulk that can pass through the dispenser valve (3) is discharged, the discharge amount of powder dye (1), i.e., housed in the bucket (7) even powder amount is increased, by weighing the powder quantity scale (8), the actual amount of powder obtained by the automatic weighing device (5) is found. これに基づく計量信号〔実際粉体量〕をスケール(8)からコンピュータ(15)にフィードバックし、コンピュータ(15)で、 The metering signal based thereon [actual amount of powder] is fed back from the scale (8) to the computer (15), a computer (15),
上記目標粉体量と実際粉体量とを比較して演算処理によりその誤差を認識する。 It recognizes the error by the arithmetic processor by comparing the actual powder weight and the target amount of powder.

【0017】一方、バケット(7)内の粉体染料(1)をスケール(8)で計量した後、アーム(6)を旋回させてバケット(7)を搬送コンベア(9)に移載した上で、その移送端まで搬送する。 Meanwhile, the bucket (7) was weighed in scales (8) Powder dye (1) in the arm (6) to be pivoted bucket (7) after having transferred to the transfer conveyor (9) in and conveyed to the transfer end. その搬送コンベア(9)の移送端では、反転機構(14)によりバケット(7)が反転されて粉体染料(1)を溶解槽(11)に移し替える。 In its transfer end of the transfer conveyor (9), transferring the dissolving tank bucket (7) is inverted pulverulent dyestuffs (1) by the reversing mechanism (14) (11).

【0018】この段階で、溶解槽(11)ではバケット(7)から移し替えられて収容された粉体染料(1)に対して、給水バルブ(12)から水が供給されて攪拌器(1 [0018] In this step, dissolving tank (11) in the bucket (7) of the powder dye (1) housed is transferred from the water supply valve (12) water is supplied agitator (1
3)でもって溶解され、液体染料が生成される。 Dissolved with 3), liquid dye is produced. この時、給水バルブ(12)からの給水量は、前述したようにコンピュータ(15)により比較して演算処理された目標粉体量と実際粉体量との誤差に基づいて制御される。 At this time, the water supply from the water supply valve (12) is controlled based on the error between the actual powder quantity and the target amount of powder that is processing compared by a computer (15) as described above. 即ち、目標粉体量に対して実際粉体量が増加したとしても、溶解槽(11)で生成される液体染料が所定濃度となるように給水量を、目標粉体量と実際粉体量との誤差分だけ所定量増加させる。 That is, even if the real amount of powder to the target amount of powder is increased, liquid dye produced by dissolving tank (11) is a water supply to a predetermined concentration, the target powder quantity and the actual amount of powder by an error with increasing a predetermined amount. このような給水バルブ(12)の開閉制御により、溶解槽(11)での液体染料の濃度を計量誤差にかかわらず常に所定値となるように一定に維持する。 The opening and closing control of such supply valve (12) always kept constant to a predetermined value irrespective of the concentration of the liquid dye at the dissolving tank (11) to the metering error.

【0019】その後、所定濃度を有する液体染料をストックタンク(17)に圧送して貯溜し、そのストックタンク(17)から計量槽(20)に一旦圧送して液体染料を計量した上で、中継槽(24)を介して染色機の染料投入槽(26)に送り込む。 [0019] Thereafter, in order to reservoir by pumping a liquid dye having a predetermined concentration to the stock tank (17), was weighed liquid dye is once pumped to the metering tank (20) from the stock tank (17), the relay through the bath (24) sent into the dye charging tank dyeing machine (26).

【0020】尚、上記実施例では、粉体溶解装置を粉体染料の自動投入システムに適用した場合について説明したが、本発明はこれに限定されることなく、その他の粉体を計量した上で溶解させて所定濃度の溶液を得る場合について適用可能である。 [0020] In the above embodiment, on the powder dissolving device has been described as applied to an automatic dosing system for the powder dye, but the present invention is not limited thereto, which was weighed other powder in dissolved it can be applied to a case of obtaining a solution of a predetermined concentration.

【発明の効果】本発明に係る粉体溶解装置によれば、目標粉体量に対して実際粉体量に誤差があっても、その実際粉体量に対する適正な給水量を常に確保できるので、 According to the powder dissolving device according to the present invention, even if there is an error in the actual amount of powder to the target amount of powder, so always ensuring proper water supply for the actual amount of powder ,
所定濃度の溶液を必ず得ることができ、液体染料の濃度管理を高精度に行える。 Predetermined concentration solution can always get the, allows the concentration control of the liquid dye with high accuracy. その結果、所定の精度を得るために計量できる粉体の最小計量値を小さく設定することが可能となり、高精度な粉体の計量が実現できる。 As a result, it is possible to set small minimum weight of the powder can be weighed to obtain a predetermined accuracy, metering precision powder can be achieved. また、このように液体染料の濃度管理、粉体の計量を高精度に行なえるので、稼働効率の向上を図ることができる。 Moreover, in this way control the concentration of the liquid dye, so perform the metering of the powder with high precision, it is possible to improve the operation efficiency.
