LOOP DEVICE AND STRAP SUPPLY SYSTEM

A loop device, comprising a loop frame (31) and at least two loopers, wherein the loopers are all fitted on the loop frame, and define an in-frame strap passage channel; and each looper comprises a looper shaft and a plurality of looper rollers adapted for strap passage, the looper rollers all passing through the corresponding looper shaft. Further provided is a strap supply system using the loop device. A strap can be stored by winding the strap around the loopers to form the in-frame strap passage channel, such that the production paces of an upstream strap unwinding supply operation and a downstream bundling operation can be effectively synchronized, thereby improving the continuity, reliability and safety of the robot bundling operation. Using a plurality of looper rollers to form a looper can significantly prolong the length of the in-frame strap passage channel, thus increasing the loop volume of the loop device.
