An article transport facility includes a transport conveyor (34) and a weighing device (24), which includes a support portion (28) for supporting a container (C1) and a measuring portion (30) configured to measure a weight of the container (C1) supported by the support portion (28). The article transport facility is configured to perform a state change between a withdrawn state in which the support portion (28) is withdrawn downward relative to a transport surface (34A) and a protruding state in which the support portion (28) protrudes upward relative to the transport surface (34A) by moving the support portion (28) and the transport conveyor (34) relative to each other in a vertical direction (Z). A support surface (28A) of the support portion (28) is inclined such that one corner portion (8A) of multiple corner portions (8) located at corners of the container (C1) is lower than the other corner portions (8).

The present invention proposes a method for identifying the spatial-temporal distribution of the vehicle loads on a bridge based on the DenseNet. The method includes five steps: firstly, mounting a plurality of cameras in different positions of a bridge, acquiring images of the bridge from different directions, and outputting video images with time tags; secondly, acquiring multichannel characteristics of vehicles on the bridge by using DenseNet, including color characteristics, shape characteristics and position characteristics; thirdly, analyzing the data and characteristics of the vehicles from different cameras at a same moment to obtain vehicle distribution on the bridge at any time; fourthly, continuously monitoring the vehicle distribution in a time period to obtain a vehicle load situation on any section of the bridge; and finally, integrating the time and space distribution of the vehicles to obtain spatial-temporal distribution of the bridge.

Method for weighing an object transported on a mover of an electromagnetic conveyor and electromagnetic conveyor. Method includes lifting object off the mover with a lifting device; setting down object onto at least one transport plane of a weighing station arranged at a weighing region of the track and arranged on at least one weigh cell. The transport plane extends in the direction of movement to support the object when in the weighing station. The method also includes actively driving object while lifted off from the mover and while supported on the transport plane with the mover as it moves along the track through a weighing region; weighing object with at least one weigh cell while the object is supported by the transport plane; and setting down object on the mover after weighing in the weighing station for onward movement of object along the track with the mover.

A method and a system measure interfering influences on a checkweighing device. In the method, external interference data are obtained, as are interference data from the checkweighing device itself and interference data from an object being weighed, by calculating or mapping the weighing error data in the stationary state, in the operating state, and in the weighing state. The system for measuring the interference uses a meter and a processing apparatus. The meter and the processing apparatus perform an interference measurement and a compensation method. The amount of interference in the checkweighing device in each state and the amount of influence of the interference on the weighing performance is obtained, thereby facilitating the production, debugging, maintenance, and use of a checkweighing device.

A weight estimation apparatus 1 includes: an impulsive force calculation unit 2 calculating an impulsive force using an acceleration response indicating vibration generated in a structure by the moving object (vehicle 27) moving through the structure, and a weight estimation unit 3 estimating a weight of the moving object using the impulsive force.

Systems and methods for an Automated Guided Vehicle (AGV) capable of automatically balancing large and heavy objects for transport through a facility. One embodiment is an Automated Guided Vehicle (AGV) including a balancing plate configured to support a load, load sensors configured to detect a weight distribution of the load, and an actuator configured to shift the balancing plate laterally.
