The belt transfer device (TDB) is a bidirectional transfer device that facilitates load transfers to or from adjacent perpendicular conveyors on either side of the device. Loads are carried during transfer on multiple strands of flat top chain powered by an electric gearmotor. Each carrier chain occupies the same space of one roller and is guided by UHMW-PE chain guides mounted on a rigid chain bar weldment. The device and load are raised and supported during transfer by multiple pneumatic actuators mounted on bases anchored to the floor.
The chain used for this device is a plastic chain with a pitch of 3/4″. This short pitch allows small radius turns that accomodate short center distances between the end of the transfer surface and adjacent conveyors. The general idea of multiple chain bars wit adjustable centers is similar to our standard chain transfer device. However a box shaped chain bar gives the device improved rigidity and protection to the plastic chain.
