Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a technology or a device which positions a processing position by a head unit more precisely.SOLUTION: A conveyance device includes a head unit, and discharges a liquid to a conveyed object, which is conveyed, by a plurality of liquid discharge head units. The conveyance device includes: an actuator which moves the head unit in an orthogonal direction orthogonal to a conveyance direction; an actuator controller which controls the actuator; a displacement sensor which detects a displacement amount of the head unit in conjunction with movement by the actuator; and a controller which outputs a command value to an actuator controller based on a detection result indicating a position, a moving speed, and a moving amount of the conveyed object in the orthogonal direction, or a combination of them, and an output of the displacement sensor.SELECTED DRAWING: Figure 1
【課題】ヘッドユニットによる処理位置をより精度良く合わせる技術又は装置を提供する。【解決手段】ヘッドユニットを有し、搬送される被搬送物に対して複数の液体吐出ヘッドユニットによって液体を吐出する搬送装置が、ヘッドユニットを搬送方向と直交する直交方向へ移動させるアクチュエータと、アクチュエータを制御するアクチュエータコントローラと、アクチュエータによる移動に伴うヘッドユニットの変位量を検知する変位センサと、直交方向の前記被搬送物の位置、移動速度、移動量又はこれらの組み合わせを示す検出結果と、変位センサの出力と、に基づいてアクチュエータコントローラへ指令値を出力するコントローラと、を備える。【選択図】図1 |
