Abstract:
(EN) Provided is a diagnosis device that is capable of separating and detecting, from the total amount of electric current in a plurality of rotary machines for conveying objects, an anomaly in the respective rotary machines. The diagnosis device is provided with: a current sensor that measures the total amount of load current in the rotary machines; a diagnosis unit that makes a diagnosis of the rotary machines on the basis of information from the current sensor; and a display unit that displays the result of the diagnosis carried out by the diagnosis unit, wherein the total amount of load current is measured during a period in which the number of rotary machines having load of an object applied thereto increases or decreases at a roughly constant rate, an increase amount of the load current of each of the rotary machines during when the object is conveyed is extracted from the increase or decrease, and an anomaly is detected on the basis of any difference in the increase amount from the normal state.
(FR) L'invention concerne un dispositif de diagnostic qui peut séparer et détecter, à partir de la quantité totale de courant électrique dans une pluralité de machines rotatives permettant de transporter des objets, une anomalie dans les machines rotatives respectives. Le dispositif de diagnostic est pourvu : d'un capteur de courant qui mesure la quantité totale de courant de charge dans les machines rotatives ; d'une unité de diagnostic qui effectue un diagnostic des machines rotatives sur la base d'informations provenant du capteur de courant ; et d'une unité d'affichage qui affiche le résultat du diagnostic effectué par l'unité de diagnostic, la quantité totale de courant de charge étant mesurée pendant une période où le nombre de machines rotatives auxquelles est appliquée une charge d'un objet augmente ou diminue à une vitesse globalement constante, une quantité d'augmentation du courant de charge de chacune des machines rotatives pendant le moment où l'objet est transporté est extraite de l'augmentation ou de la diminution, et une anomalie est détectée sur la base de toute différence de quantité d'augmentation par rapport à l'état normal.
(JA) 物体を搬送する複数の回転機の電流の総和から、個々の回転機の異常を分離して検知可能な診断装置を実現する。 回転機の負荷電流の総和を計測する電流センサと、電流センサからの情報により回転機を診断する診断部と、診断部で診断した結果を表示する表示部とを備え、物体の荷重が加わる前記回転機の台数が略一定速で増減する期間の負荷電流の総和を計測し、その増減から前記物体の搬送時の前記各回転機の負荷電流の増加分を抽出し、その正常状態との差分により異常を検知する。
