Bed foundation beams are sandwiched by a compression bar extending parallel to the first and second rails and moved towards the first and second rails while being conveyed. Further, the first and second rails and the spacers are sandwiched against spaced fixtures on an endless chain. While being compressed and sandwiched, staple guns fasten the rails and spacers together. The fixtures include front and back stops, with the back stop pivotable about a fixture axis to be movable by a cam moving in a cam track from a pushing position extending perpendicular to the endless chain and abutting with a trailing edge of one of the spacers and a non-intervening position after the staple gun and before the sprocket of the endless chain to reduce the apparatus footprint.

A board turner assembly may include an endless chain, first and second groups of turning arms pivotably coupled with the endless chain and disposed along opposite sides thereof, an upper guide with an inclined surface, an actuator selectively operable to move the upper guide between a resting position and an extended position, and one or more endless belts. The turning arms may be spaced apart at regular intervals that are offset on one side of the chain relative to the other. The groups of turning arms may be operated in an alternating fashion to turn selected boards to a desired orientation (e.g., wane side up). Corresponding methods and systems are also described.

An automated baggage conveyor and storage system used in a transportation vehicle for receiving baggage from a passenger. The system includes a vertical conveyor, with drive motor. The vertical conveyor includes baggage trays mounted on a conveyor belt and under the control of an electronic sensor for starting and stopping the conveyor belt. Next to the top of the vertical conveyor is one end of a motor driven, horizontal conveyor. When a passenger places a piece of baggage on one of the trays, it is lifted to the top of the vertical conveyor and transferred to the horizontal conveyor. The piece of baggage is then moved along a length of the overhead storage compartment, where the baggage remains stored during transit.

A cleaning device is provided with a three-dimensional circulation route for circulating workpiece holding tools that hold a workpiece, and this three-dimensional circulation route is formed by an endless conveyor chain bendable in various directions being disposed within a rectangular parallelepiped space following along the upper and lower sides thereof. The conveyor chain circulates from an upper side horizontal transport path portion via a falling side transport path portion, a lower side horizontal transport path portion, and a rising side transport path portion, and the workpiece held in the workpiece holding tools is treated by ultrasonic cleaning, shower cleaning, steam cleaning, drying and the like. Thus, it is possible to suitably dispose a workpiece transport route in a limited rectangular parallelepiped space, and carry out cleaning operations for the workpiece efficiently.
