Non-contact type edge-removing detection mechanism for setting machine fabric and setting system

The utility model discloses a non-contact type edge falling detection mechanism for a setting machine fabric. The non-contact edge-removing detection mechanism for the fabric of the setting machine comprises a fabric detector, an edge-removing detector, a memory, an alarm and a controller, wherein the fabric detector is used for detecting whether the fabric exists on a chain of the setting machineor not; the edge removing detector is used for detecting whether the fabric on the chain is subjected to edge removing or not; the controller is connected with the fabric detector and the edge removing detector, and the controller is used for processing fabric detection information of the fabric detector and edge removing detection information of the edge removing detector; the memory is used forstoring fabric detection information and edge removal detection information, and the alarm is used for giving an alarm; and the controller is electrically connected with the fabric detector, the edgeremoving detector and the
