Edible-body marking device and method therefor

An edible-body marking device comprising:

• a carrier device that carries an edible body,
• a detection part that detects the edible body, and
• a laser processing part that forms a marking pattern on the edible body by using laser light, wherein the carrier device sequentially carries the edible body to the detection part and the laser processing part, wherein
• the detection part images the edible body to acquire a piece of orientation information regarding an orientation of the edible body such that the orientation of the edible body is determined by the detected piece of the oriental information, and
• the laser processing part
• has a memory part that stores in advance coordinate information of the marking pattern in a reference coordinate system, and multiple pieces of marking procedure information regarding formation procedures of the marking pattern in association with their respectively different pieces of the orientation information,
• converts the coordinate information of the marking pattern in the reference coordinate system into coordinate information in a processing coordinate system based on the piece of the orientation information acquired by the detection part, thereby forming the marking pattern in accordance with the orientation of the edible body,
• each of the multiple pieces of the marking procedure information contains a unique start point data representing coordinate information of a start point of the marking pattern in the reference coordinate system, the start point data being different among the multiple pieces of marking procedure information, so that each of the formation procedures starts at a different point in the reference coordinate system according to the start point data associated with the detected piece of the orientation information, and
• the laser processing part forms the marking pattern on the edible body according to one piece of the marking procedure information extracted from the memory part based on the detected piece of the orientation information acquired by the detection part.

An edible-body marking method comprising:

• a detection step that detects an edible body carried by a carrier device, and
• a marking step that form a marking pattern on the edible body, wherein
• the detection step images the edible body to acquire a piece of orientation information regarding an orientation of the edible body such that the orientation of the edible body is determined based on the detected piece of the orientation information, and
• the marking step includes a step of acquiring the marking pattern on the edible body according to one piece of marking procedure information extracted based on the detected piece of the orientation information acquired in the detection step from a memory part that memorizes, in advance, coordinate information of the marking pattern in a reference coordinate system, and multiple pieces of marking procedure information in association with respectively different pieces of the orientation information, wherein
• each of the multiple pieces of the marking procedure information contains a unique start point data representing coordinate information of a start point of the marking pattern in the reference coordinate system, the start point data being different among the multiple pieces of marking procedure information, so that each of the formation procedures starts at a different point in the reference coordinate system based on the start point data associated with the detected orientation information according to the start point data associated with the detected piece of the orientation information, and
• the marking step includes a step of forming the marking pattern by converting the coordinate information of the marking pattern in the reference coordinate system into coordinate information in a processing coordinate system based on the orientation information.

• the laser processing part that stores in advance coordinate information of the marking pattern in a reference coordinate system in a memory part, forms the marking pattern on the edible body by extracting marking procedure information regarding formation procedures of the marking pattern and by converting the coordinate information of the marking pattern in the reference coordinate system into coordinate information in a processing coordinate system, thereby forming the marking pattern in accordance with the orientation of the edible body, based on the detected piece of the orientation information acquired by the detection part,
• each of the multiple pieces of the marking procedure information contains a unique start point data representing coordinate information of a start point of the marking pattern in the reference coordinate system, the start point data being different among the multiple pieces of marking procedure information so that a point from which the formation procedures of the marking pattern start varies, in the reference coordinate system, according to the detected piece of the orientation information.
