A loading system for loading a bone-in limb meat to a processing portion, the loading system comprising: an image capturing portion configured to capture an image of the bone-in limb meat to be loaded to the processing portion, the bone-in limb meat being placed on a holding surface (Pm); an image processing portion configured to acquire orientation information of the bone-in limb meat from the image of the bone-in limb meat captured by the image capturing portion; a tip tool configured to hold the bone-in limb meat; an arm configured to support the tip tool, and control a position and orientation of the tip tool; and a control portion configured to control, based on the orientation information acquired by the image processing portion, at least an operation of the arm to hold a limb neck part (f) of the bone-in limb meat, and load the bone-in limb meat to the processing portion in a predetermined direction, characterized in that: the loading system comprises a plurality of hangers configured to suspend and convey the bone-in limb meat toward the processing portion; in that the orientation information includes front/back surface information indicating whether an upper surface of the bone-in limb meat on the holding surface (Pm) is a front surface or a back surface; and in that the control portion is configured to control the operation of the arm on the basis of the orientation information including the front/back surface information so as to cause the tip tool to suspend the bone-in limb meat to one of the plurality of hangers such that a front surface of the bone-in limb meat faces a predetermined direction. an image capturing portion configured to capture an image of the bone-in limb meat to be loaded to the processing portion, the bone-in limb meat being placed on a holding surface (Pm); an image processing portion configured to acquire orientation information of the bone-in limb meat from the image of the bone-in limb meat captured by the image capturing portion; a tip tool configured to hold the bone-in limb meat; an arm configured to support the tip tool, and control a position and orientation of the tip tool; and a control portion configured to control, based on the orientation information acquired by the image processing portion, at least an operation of the arm to hold a limb neck part (f) of the bone-in limb meat, and load the bone-in limb meat to the processing portion in a predetermined direction, characterized in that: the loading system comprises a plurality of hangers configured to suspend and convey the bone-in limb meat toward the processing portion; in that the orientation information includes front/back surface information indicating whether an upper surface of the bone-in limb meat on the holding surface (Pm) is a front surface or a back surface; and in that the control portion is configured to control the operation of the arm on the basis of the orientation information including the front/back surface information so as to cause the tip tool to suspend the bone-in limb meat to one of the plurality of hangers such that a front surface of the bone-in limb meat faces a predetermined direction. the loading system comprises a plurality of hangers configured to suspend and convey the bone-in limb meat toward the processing portion; in that the orientation information includes front/back surface information indicating whether an upper surface of the bone-in limb meat on the holding surface (Pm) is a front surface or a back surface; and in that the control portion is configured to control the operation of the arm on the basis of the orientation information including the front/back surface information so as to cause the tip tool to suspend the bone-in limb meat to one of the plurality of hangers such that a front surface of the bone-in limb meat faces a predetermined direction.
