LIQUID APPLYING APPARATUS AND METHOD FOR MAINTAINING LIQUID APPLYING APPARATUS

摘要

A liquid applying apparatus includes a feeding container; first and second liquid-supply containers for supplying a liquid to the feeding container; a switch for switching a supply source between the first and second liquid-supply containers; a first storage for storing a supply start time of a supply operation; a second storage for storing supply information including a supply source or a supply route; a third storage for storing a liquid level in the feeding container at the supply start time; a fourth storage for storing a supply operation time of the supply operation; a controller that determines a condition of the liquid applying apparatus based on the supply operation time, and determines the supply source or the supply route as an inspection-required spot based on the supply information when the liquid applying apparatus is in a potentially-abnormal condition; and a fifth storage for storing the inspection-required spot.

主权项

1. A liquid applying apparatus comprising:
at least one application unit including a feeding container configured to contain a liquid, the application unit being configured to apply the liquid to an object; a first liquid-supply container configured to supply the liquid to the feeding container; a second liquid-supply container configured to supply the liquid to the feeding container; a switch configured to switch a supply source of the liquid between the first liquid-supply container and the second liquid-supply container; a first storage configured to store a supply start time when a supply operation to supply the liquid to the feeding container is started, the supply operation being performed to fill the feeding container with the liquid up to a predetermined supply level; a second storage configured to store supply information including one of supply source information indicating the supply source of the liquid and supply route information indicating a supply route through which the liquid is supplied; a third storage configured to store a liquid level of the liquid in the feeding container at a start of the supply operation; a fourth storage configured to store a supply operation time from the start of the supply operation until the liquid in the feeding container reaches the predetermined supply level; a controller configured to
determine, after the supply operation is completed, a condition of the liquid applying apparatus based on the supply operation time stored in the fourth storage as one of a normal condition, an abnormal condition requiring a repair, and a potentially-abnormal condition that is different from both of the normal condition and the abnormal condition, anddetermine the supply source or the supply route as an inspection-required spot based on the supply information stored in the second storage when the liquid applying apparatus is determined to be in the potentially-abnormal condition; and a fifth storage configured to store the inspection-required spot determined by the controller.
