The present disclosure provides a whole-process automatic loading-and-unloading and logistics system, including an outer yarn preparation area, an inner yarn preparation area, a weaving area and an in-air conveying rail; the outer yarn preparation area is configured to have a carrier assembly, which delivers an outer yarn winding package to an outer yarn branch rail of a twisting machine in a twisting area via the out yarn main rail of the in-air conveying rail; in the inner yarn preparation area, the carrier assembly delivers an inner yarn winding package to an inner yarn branch rail of the twisting machine in the twisting area via the inner yarn main rail of the in-air conveying rail; in the twisting area, the carrier assembly delivers a yarn product to a yarn product donning rail in the weaving area via the yarn product main rail of the in-air conveying rail.

A conveyance facility for conveying a bag includes a carrier including a support supporting the bag, and traveling wheels. A conveyance path includes a straight section and a curve section. In the curve section, a pulley rotatable along the curve section and in frictional contact with the support; and a guide rail guiding the traveling wheels are provided. The guide rail includes a rotation guide rail guiding one traveling wheel of a pair of the traveling wheels, and rotating with the pulley; a fixed guide rail guiding another traveling wheel of the pair of traveling wheels, and being provided along the rotation guide rail; and an upper guide rail and a side guide rail guiding the support.

A movable rail is retracted even when positions of an upstream rail and a downstream rail fluctuate, and an increase in distance between the upstream rail or the downstream rail and the movable rail is reduced or prevented. The movable rail is movable between a first position and a second position, and an extendable rail is provided on the upstream rail. The extendable rail includes one end coupled with the upstream rail and the other end defining a free end, and extending and contracting with an elastic member. The extendable rail contracts while leaving room for the other end of the extendable rail to be pushed by the movable rail moving toward the first position and further contract. When the movable rail moves to the second position, a space through which a fire shutter provided in the building is able to pass is provided between the other end and the downstream rail.

An overhead conveyor for conveying heavy loads such as lorry frame components, lorry trailers or the like, the overhead conveyor having passive travelling mechanisms guided on rails for receiving the heavy load, wherein at least two passive travelling mechanisms are connected via a load-bearing crossmember to form a passive carrier, and the load-bearing crossmember is designed to receive the heavy load, extends substantially along the conveying direction, and is mounted underneath the passive travelling mechanism, and at least one stationary drive device for introducing a driving force into the passive carrier, wherein the drive device has a friction wheel-counter wheel arrangement and a contact device, the friction wheel being mounted on one side of the load-bearing crossmember in order to transmit the driving force to the load-bearing crossmember, and the counter wheel being mounted, transverse to the conveying direction, on the side of the load-bearing crossmember opposite said first side in order to transmit a transverse force to the load-bearing crossmember and/or to absorb a transverse force from the load-bearing crossmember, wherein a contact force is exerted by means of the contact device via the counter wheel and/or via the friction wheel in the direction of the load-bearing crossmember. The drive device has a preloading device designed to apply an additional preloading force to the contact device.

A conveyor system comprising a fixed, non-powered rail defining a conveyor path and an automated conveyor carrier (ACC) supported on the rail to be movable along the conveyor path. The ACC includes an on-board motor and an on-board electrical power source selectively powering the on-board motor to drive the ACC along the rail. The ACC may include a wireless sleep mode module operable to selectively shut off power to an on-board ACC controller.

Overhead transport vehicles with a hoist travel on a traveling rail for the overhead transport vehicles including a straight segment and a curved segment. A traveling rail for a local vehicle is provided below the traveling rail for the overhead transport vehicles, allows articles passing upward and downward over the traveling rail, has one end below the straight segment, extends from the one end parallelly to an extended line of the straight segment to a transfer position at the ground side, and has the other end outside an area under the straight segment. A buffer for the articles is provided below the straight segment and also below the traveling rail for the local vehicle. The local vehicle with a hoist traveling on the traveling rail for the local vehicle transfers the articles between the transfer position at the ground side and the buffer.

A cloth transfer apparatus allows a cloth to be attached to a traveling clamp efficiently without waste even when a corner of the cloth to be attached to the traveling clamp is specified. The cloth transfer apparatus includes: a plurality of independent traveling clamps; and a transfer rail circulating through a supply unit where a corner of the cloth is attached to the traveling clamp and a discharge unit where the cloth is delivered from the traveling clamp and allowing the traveling clamps to independently travel. In the supply unit: a branch point that allows the transfer rail to branch into a first supply rail and a second supply rail and a merge point that allows to the branched first supply rail and second supply rail to be merged.

A method of transporting a vehicle engine wire harness from a component preparation location to a component pick location is provided. The method includes placing the vehicle engine wire harness on a hook of a component hanger. The component hanger with vehicle engine wire harness is directed along a supply track assembly through a heated enclosure to the component pick location at a vehicle assembly line.

A conveyance facility for conveying a bag includes a carrier including a support supporting the bag, and traveling wheels. A conveyance path includes a straight section and a curve section. In the curve section, a pulley rotatable along the curve section and in frictional contact with the support; and a guide rail guiding the traveling wheels are provided. The guide rail includes a rotation guide rail guiding one traveling wheel of a pair of the traveling wheels, and rotating with the pulley; a fixed guide rail guiding another traveling wheel of the pair of traveling wheels, and being provided along the rotation guide rail; and an upper guide rail and a side guide rail guiding the support.

A conveyance facility for conveying a bag includes: a carrier including a traveling wheel, and a support supporting the bag being suspended, the carrier conveying the bag; and a traveling rail supporting the traveling wheel so as to be travelable. The traveling rail forms a first path, and a detour path branching from a location in the middle of the first path. A branch unit for switching a conveyance path of the carrier from the first path to the detour path is provided at a branch portion between the first path and the detour path. The branch unit is capable of directing the support from the first path to the detour path.
