Abstract: In a local cart traveling system, a frame track includes first and second metal rails each with an L-shaped cross section and facing each other. A local cart is within the frame track, and includes a first electricity receiving tire and a second electricity receiving tire to travel on horizontal travel surfaces of the rails. A voltage supplier supplies an AC voltage to the travel surfaces, so that the first metal rail and a first electricity receiving tire define a first capacitor and the second metal rail and the second electricity receiving tire define a second capacitor. The local cart includes a power receiver to receive AC power, and a travel motor that receives power after the AC power is rectified. The frame track includes a connecting plate as an electrical insulator covering portions of the surfaces of vertical walls of the first metal rail and the second metal rail.

Abstract: In a stacker crane, a cover to cover an elevation area of an elevation portion is integrally attachable to side surface portions of a mast, which includes a reinforcement portion and an adjuster. The reinforcement portion between a pair of the side surface portions in a Y direction extends toward an opposite direction to an elevation surface of an elevation surface defining portion and has a higher stiffness than that of each of the pair of side surface portions. The adjuster is spaced from the elevation surface defining portion in an X direction perpendicular to a Z direction and the Y direction, and both edges thereof extendible in the Y direction are contactable with the reinforcement portion and each of the pair of side surface portions.

Abstract: A conveyance system includes a traveling area and a suspension traveling vehicle. The traveling area includes a grid area and a linear area. In the grid area, since first tracks are disposed side by side and second tracks are disposed side by side so that the first tracks and the second tracks intersect, the grid area includes unit blocks of the same shape or substantially the same shape surrounded by the first tracks and the second tracks. Both the first tracks and the second tracks surrounding the unit blocks are provided with an interstice that allows a supporting body to pass, and the interstice is perpendicular or substantially perpendicular to a longitudinal direction of each track. A traveling direction is the same or substantially the same as the first direction or the second direction in the linear area, and the interstice perpendicular or substantially perpendicular to the traveling direction is not provided in the linear area.

Abstract: A traveling vehicle system includes a track and a ceiling traveling vehicle. The track includes a first track, a second track, and a connection track. The ceiling traveling vehicle includes a direction changer that turns a coupler, which couples a traveling wheel and a main body to each other and passes through a gap between the first track or the second track and the connection track. A guider is provided in the coupler, moves along a first guide surface in a first state in which the traveling wheel rolls on the first track, and moves along a second guide surface in a second state in which the traveling wheel rolls on the second track.

Abstract: A lifting and lowering transportation device is capable of transporting articles between different delivery positions using transportation units, each including a lifting and lowering platform, a linear motor, and a chain. The lifting and lowering platform can pass through the delivery positions by moving along the circumferential track that is common to the transportation units. The linear motor generates the driving force to move the lifting and lowering platform along the circumferential track. The chain is loop-shaped and can circulate along the circulation track corresponding to the circumference path, and the linear motor moves the lifting and lowering platform by circulating the chain by the driving force generated by the linear motor. The circulation of the chain in each transportation unit is controlled independently of the other transportation units.

Abstract: An article transferring device that transfers articles includes: a traveling rail; primary-side stators; a power source; a first transporting carriage and a second transporting carriage each of which includes a secondary-side movable element and transports an article by the secondary-side movable element receiving a magnetic action from the primary-side stators. Each of the first transporting carriage and the second transporting carriage is caused to travel so as to be stopped or change a traveling speed individually by a ground primary-side linear motor system including the primary-side stators and the secondary-side movable element, and further includes a transferring unit that transfers the article in an intersecting direction intersecting with the predetermined path by receiving force from the power source.
