A loading system for loading a bone-in limb meat (W) to a processing portion , the loading system comprising: an image capturing portion configured to capture an image of the bone-in limb meat (W) to be loaded to the processing portion , the bone-in limb meat (W) 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 (W); 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 (W), 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 (W) 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 (W) 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 (W) 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 (W) to be loaded to the processing portion , the bone-in limb meat (W) 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 (W); 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 (W), 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 (W) 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 (W) 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 (W) 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 (W) 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 (W) 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 (W) to one of the plurality of hangers such that a front surface of the bone-in limb meat faces a predetermined direction. <EOS>
