An interception mechanism for conveyor belt production line abnormality includes a conveyor belt device for transporting bottles; at least an interception cylinder movably disposed on one side of the conveyor belt device; and a plurality of fullness sensing devices disposed on one side of the conveyor belt device at intervals. When at least two of the fullness sensing devices simultaneously sense the bottles passing, the interception cylinder stops the bottles from continuing to move forward. When only one of the fullness sensing device senses the bottles passing at one time, the interception unit returns to its original position, allowing the bottles to continue to move, ensuring a stable bottle transportation, preventing bottles from piling up at the outlet, thereby improving the production efficiency of the production line.

A conveying system, the conveying system including a conveyor arranged for conveying a storage container; a body shaped to comprise a ramp to enable the storage container to move along a first path and a substantially vertical face forming a stopping surface for stopping the storage container from moving along a second path; wherein the body is moveable between a retracted position to permit movement of the storage container along the first path of the conveyor and a raised position to prevent movement of the storage container along the second path of the conveyor; the second path being directionally opposite to the first path; wherein the body is resiliently biased in the raised position and the bias is overcome by the storage container riding over the ramp.
