To provide a net ejection device which deploys a net sufficiently when capturing an object to be captured (a captured object) to enable easy capturing of the captured object.SOLUTION: A net ejection device includes: a device body 11 including a net storage part 40 which opens in a net ejection direction; a net 60 for capturing the captured object; multiple weights 50 respectively attached to positions of an outer periphery of the net 60; multiple weight ejection mechanisms 30 each of which ejects the weight 50 in a radial direction which spreads from the net ejection direction at a predetermined weight ejection angle by using a spring; a weight ejection angle change mechanism 20 which changes the weight ejection angle of each weight ejection mechanism 30; operation actuators each of which actuates the weight ejection mechanism 30; distance sensors 70 which measure a distance to the captured object; and a control unit 80. The control unit 80 is configured to change the weight ejection angle of each of the multiple weight ejection mechanisms 30 according to the distance to the captured object and eject the weights 50 so that the net 60 sufficiently deploys immediately before reaching the captured object.SELECTED DRAWING: Figure 1
【課題】捕獲対象の捕獲時に網が十分に展開し、捕獲対象を捕獲しやすい網射出装置を提供する。【解決手段】網射出方向に開口した網収納部40を備えた装置本体11と、捕獲対象物を捕獲するための網60と、網60の外周のそれぞれの箇所に取付けられた複数の錘50と、複数の錘50を、網射出方向から所定の錘射出角度で広がる放射状の方向に、バネを用いてそれぞれ射出する複数の錘射出機構30と、錘射出機構30の錘射出角度を変更する錘射出角度変更機構20と、錘射出機構30を作動させる作動アクチュエータと、捕獲対象物までの距離を測定する距離センサ70と、制御部80と、を有し、制御部80は、網60が捕獲対象物に到達する直前に十分に展開するように、捕獲対象物までの距離に応じて複数の錘射出機構30の錘射出角度を変更して、錘50を射出するように構成した。【選択図】図1
