Multi-Conveyor recently built this dual strand, roller chain conveyor with bucket-style attachments to transport loaves of bread - ultimately ending up at a robotic pick zone. Alternating back-to-back buckets are horizontal and rotated 45-degrees.
The back-to-back design was specified based on how the loaves were being both loaded and unloaded. Dual strand stainless steel roller chain designs may have pre-tensioned linkage with attachments needed for the customized buckets. This design required every-other-bucket 45 degree rotation.
Another unique customer request were square cutouts in lower end of the buckets for customer-supplied photo eyes to detect product inside the buckets. Sanitary requirements were stainless steel, continuous and cleaned welded design . Heavy duty brackets were added to mount inside the customer's bread making machine providing additional stability and alleviating any flex in the conveyor itself.
In general, the customer requested a "beefy design" for longevity, bucket placement and timing, simplistic bucket cleaning by removal and replacement of buckets, and overall maintenance purposes.
