【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、走行材料へ水、インキ、強化剤等の液状吹
付物を吹付ける方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for spraying a liquid sprayed material such as water, ink, and a reinforcing agent on a running material.
段ボールシート等のような走行材料へ水、インキ、強化
剤等の液状吹付物を全面に、あるいは部分的に吹付ける
場合、そのいずれの場合も一般に走行材料の走行速度が
変化すればその変化に応じて吹付量を自動調整して走行
材料への付着量が一定になるようするのが望ましい。When spraying liquid, such as corrugated cardboard sheet, with water, ink, reinforcing agent, etc. over the entire surface or partially, in either case, generally, if the traveling speed of the traveling material changes, it will change. Accordingly, it is desirable to automatically adjust the spraying amount so that the amount of adhesion to the running material becomes constant.
このような液状吹付物の吹付量を自動調整する方法が、
特公平２−６５７７号公報により既に公知である。A method of automatically adjusting the spraying amount of such liquid sprayed products,
It is already known from Japanese Patent Publication No. 2-6577.

走行材料の単位面積当りの吹付量を一定に保つように制
御されて吹付けられる。According to the spraying method of this publication, the air pressure in the space above the liquid level of the sealed tank that feeds the liquid sprayed material by the water head to the nozzle array having at least one nozzle row arranged across the traveling material is traveled. By controlling the discharge pressure of the nozzle array by controlling according to the traveling speed of the material, the amount of the traveling material sprayed per unit area is controlled and sprayed.

応答が遅れてしまい、応答性が悪いという問題がある。However, in the above-described conventional method for spraying a liquid sprayed object, the air pressure in the space above the liquid surface of the tank is adjusted by detecting the traveling speed of the traveling material and controlling the air pressure in accordance with the speed. Therefore, the flow path from the tank to the nozzle is long. Therefore, if there is a speed change, the response will be delayed even if it is desired to immediately change the spray amount at the nozzle tip, and there is the problem of poor responsiveness.
また、このような走行速度の変化に対応する応答性が悪
いため、走行材料の所定長さ部分に液状吹付物を吹付け

ような吹付長さ調節を最適に制御する方法については何
ら開示されていない。In addition, since the responsiveness corresponding to such a change in traveling speed is poor, even when it is desired to spray the liquid sprayed product on the predetermined length portion of the traveling material, it is not easy to adjust the spraying length. There is no disclosure of how to optimally control such spray length adjustment.
従って、上記従来の方法により例えばノズル１つを用い

を塗布することはできない。Therefore, when it is desired to attach a mark while the corrugated cardboard sheet is running by using the above-mentioned conventional method, for example, it is impossible to accurately and uniformly apply the ink to the required mark length of 10 to 15 cm.

る。As another means for solving the above problems, a valve that opens and closes a path of air supplied to the nozzle is provided, and the traveling speed is divided into a plurality of speed stages for each predetermined range, and based on the detection result. A control signal for each speed stage is given to the valve to change the nozzle spraying time for each speed stage to control the spraying amount constantly, and to spray the liquid sprayed product so that the spraying length is almost equal. The spraying method was adopted.

The former controls the needle position so as to open and close the opening 155 of the spray nozzle 15, and the latter controls the injection time of the air injected from the nozzle. Thus, the signal is sent from the sequencer 19.

いう利点が得られる。As described above in detail, in the spraying method according to the present invention, the axial position of the nozzle driving unit is controlled by the control signal based on the traveling speed signal of the traveling material to adjust the needle position of the spray nozzle to spray the liquid sprayed product. Since the amount is increased / decreased, the spray amount becomes constant with good response to the change in the running speed regardless of the change. At the same time using the above spraying method,
When another control signal based on the traveling speed signal is generated by dividing it into a plurality of stages for each traveling speed within a predetermined range, and the spraying time of the spray nozzle is changed by opening and closing the valve with each control signal, the spraying length Can be made constant, which is an advantage.

特徴とする走行材料への液状吹付物の吹付方法。1. A nozzle for spraying a liquid sprayed object and a nozzle drive section for adjusting the needle position of the nozzle by axial movement of a projecting shaft are provided facing the traveling material, and the traveling speed of the traveling material is detected. To control the axial position of the protruding shaft of the nozzle drive unit by changing the needle position of the nozzle to adjust the opening amount of the nozzle to adjust the injection amount of the liquid sprayed material to the traveling speed. The method for spraying a liquid sprayed material onto a running material is characterized in that the spraying amount is changed so as to be constant in proportion to the spraying amount.

方法。2. A valve that opens and closes a path of air supplied to the nozzle, divides a traveling speed into a plurality of speed stages for each predetermined range, and a control signal for each speed stage based on the detection result. Is applied to the valve to change the nozzle spraying time for each speed stage, to constantly control the spraying amount and spraying so that the spraying length is almost constant (1). A method for spraying a liquid sprayed material onto the running material according to.
