Driven rollers for controlled transport of unit loads.
Driven rollers that move unit loads at a set speed and hold them when the machine downstream is not ready.
Scroll to walk the assembly. Each step picks out the parts it describes in colour and leaves the rest in plain steel.
Two shaft-mounted gear units sit under the bed at 975 mm centres rather than one at the end. Splitting the drive is what lets the two halves of the bed run independently — the basis of accumulation, where one zone holds product while the next keeps moving. Each unit turns a 14-tooth sprocket onto BS 08B ½in chain, which runs roller to roller inside the side frame.
Twenty-eight Ø62 rollers on an 89 mm pitch make up the carrying surface. Each one carries a duplex sprocket: one row of teeth takes drive from the roller behind it and the second passes it on to the roller ahead, so a single chain run powers the whole bed.
Retro-reflective sensors look across the width to a reflector on the far frame, so a pack breaking the beam tells the controller a zone is occupied. That signal is what stops the zone behind it and turns a driven bed into an accumulating one.
Two 2.5 m folded channels carry every roller shaft and hide the chain run inside their depth. Roller pitch is set by the hole line punched into them, so spacing is fixed at fabrication rather than adjusted on assembly.
Three pairs of 50 × 50 legs, cross-braced and gusseted, stand the bed at roughly 795 mm overall. M16 levelling pads at each foot true the deck on an uneven floor — important on a roller bed, where a twist in the frame shows up immediately as product drifting to one side.
