Abstract:
1. A high performance washing inducing transfer unit using wire connected rollers, the transfer unit comprising: two support structures, which are spaced apart from each other in a transverse direction thereof and respectively include a plurality of mounts in a longitudinal direction thereof; a plurality of bottom rotary transfer structures, each of which includes a bottom shaft, two bottom transfer rollers respectively coupled to both ends of the bottom shaft, and a bottom connection means including “x” wires (here, “x” is an integer number of 2 or larger), the wires being radially arranged around the outer circumference of the bottom shaft while being respectively connected at both ends thereof to the bottom transfer rollers, wherein the bottom shaft is rotatably mounted to both odd number mounts aligned on the same transverse line between the two support structures and wherein the two bottom transfer rollers are located inside the two support structures; a plurality of top rotary transfer structures, each of which includes a top shaft and two top transfer rollers respectively coupled to both ends of the top shaft, wherein the top shaft is rotatably mounted to both odd number mounts so as to be located above the bottom shaft and wherein the two top transfer rollers are located inside the two support structures so as to face the two bottom transfer rollers each other; a drive device configured to rotate the bottom and top shafts of the bottom and top rotary transfer structures, thereby enabling transfer of a target object between the bottom and top rotary transfer structures; a plurality of intermediary rotary transfer structures, each of which includes an intermediary shaft, two intermediary transfer rollers respectively coupled to both ends of the intermediary shaft, and an intermediary connection means including “z” wires (here, “z” is an integer number of 2 or larger), the wires being radially arranged around the outer circumference of the intermediary shaft while being respectively connected at both ends thereof to the intermediary transfer rollers, wherein the intermediary shaft is rotatably mounted to both even number mounts aligned on the same transverse line between the two support structures and wherein the two intermediary transfer rollers are located inside the two support structures; and linkage devices configured to transmit power of the drive device to the intermediary shafts of the respective intermediary rotary transfer structure in order to rotate the intermediary shafts, wherein the intermediary rotary transfer structures are divided into bottom intermediary rotary transfer structures arranged parallel to the bottom rotary transfer structures and top intermediary rotary transfer structures arranged parallel to the top rotary transfer structures, and wherein the linkage devices are divided into bottom linkage devices for the bottom intermediary rotary transfer structures and top linkage devices for the top intermediary rotary transfer structures.
