Abstract: An article conveying facility in which an article is conveyed by a conveyance carriage travelling on a pair of left and right rails provided along a conveyance path. The article conveying facility includes a carriage driving apparatus that drives the conveyance carriage by utilizing a frictional force generated by contact with the conveyance carriage, and sensors that detect floating of the conveyance carriage with respect to the rails. The conveyance carriage includes a fin that contacts the carriage driving apparatus. The fin is provided so as to extend along the travelling direction of the conveyance carriage, at a lower position than the position of an upper surface of the rails. The sensors detect floating of the conveyance carriage with respect to the rails by detecting the fin.

Abstract: When an external force applied condition that an external force that causes a decrease in a rotational speed of an electric motor is applied to the contact member moved by the electric motor is satisfied while the actuation controller is performing a first control for continuously performing a process of providing the electric motor with a command value that depends on an error between an actual rotational speed of the electric motor and a first target rotational speed so as to cause the actual rotational speed to approach the first target rotational speed, then the actuation controller, subsequent to the first control, performs a second control for providing the electric motor with a command value that allows the actual rotational speed of the motor to be equal to, and to fall below, the first target rotational speed at a time of the external force applied condition becoming satisfied.

Abstract: An article transport facility includes a main conveyor device and induction conveyors. The main conveyor device includes belt conveyors and carriage bodies. The induction conveyor includes a first conveyor device for loading article onto a second transport path and a second conveyor device that is provided for an article-loading position on a transport path and loads the article onto the belt conveyor. The first conveyor device adjusts the timing of loading the article to the article-loading position, by controlling the timing of loading the article onto the second conveyor device. The second conveyor device adjusts, on the belt conveyors, loading position of the article loaded onto the belt conveyor by controlling the timing of loading the article onto the belt conveyor.

Abstract: A control apparatus monitors an amount of time that has elapsed since an article was stored at a first storage position or an amount of positional misalignment from a reference position of the article stored at the first storage position. This amount of time is a monitoring target amount, and the control apparatus monitors the monitoring target amount for each of multiple storage sections and causes a conveying apparatus to execute correction processing with a storage section in which the monitoring target amount has exceeded the set threshold as a target storage section. Correction processing is used for correcting the position of only the target article stored at a first storage position in a target storage section relative to a reference position.

Abstract: A sorting facility for sorting articles by a plurality of connected conveyance carriages. The sorting facility includes a supervisory controller managing a position of each of the conveyance carriages, a trigger sensor detecting each of the conveyance carriages, and a belt conveyor provided on each of the conveyance carriages. The supervisory controller identifies each of the conveyance carriages that should deliver the articles to the chute based on the managed position of each of the conveyance carriages. The supervisory controller instructs the belt conveyor provided in each of the conveyance carriages identified to start a delivery operation of each of the articles at timing when each of the conveyance carriages identified is detected by the trigger sensor.

Abstract: A main controller controls carry in operations and carry out operations of articles to or from an article storage rack using article transport devices by causing a control command to be transmitted from a first optical communication device that is associated with each article transport device to a second optical communication device provided to each article transport device. The main controller is configured to perform a temporally-divided light-emission control in which a plurality of the first optical communication devices are caused to emit light in a temporally divided manner such that there is only one first optical communication device that emits light in any one time period among the first optical communication devices that are located close to one another in the vertical direction.
