Abstract
A press machine includes a storage unit configured to store moving image data captured by an imaging unit disposed at a position configured to allow the imaging unit to capture an image of a press die area, an image extraction unit configured to extract, from a group of still images forming the moving image data, a monitoring target image with reference to a position of a slide in the image or a state of a material to be processed, and an image monitoring unit configured to perform image monitoring based on the monitoring target image and to output a monitoring result.
Claims8
A press machine configured to convert rotation of a motor into reciprocating linear motion of a slide and to press a material to be processed, the press machine comprising:
- a storage configured to store moving image data captured by an imaging unit disposed at a position configured to allow the imaging unit to capture an image of a press die area;
- and
- a processor configured to:
- extract, from a group of still images forming the moving image data, a still image as a monitoring target image, in which a position of the slide and a movement direction of the slide are the same as the position of the slide and the movement direction of the slide detected from the still image selected in advance by a user, the movement direction of the slide being determined from the positions of the slide in the still images of frames before and after the still image, or
- compare a reference monitoring area based on a state of the material to be processed selected in advance by the user or set automatically in a still image of the group of still images forming the moving image data with a reference monitoring area in a still image of a next frame and extract, as a monitoring target image, a matching still image;
- and
- perform image monitoring based on the monitoring target image and to output a monitoring result.
A method of monitoring an image of a press machine configured to convert rotation of a motor into reciprocating linear motion of a slide and to press a material to be processed, the method comprising:
- a storage step of storing moving image data captured by an imaging unit disposed at a position configured to allow the imaging unit to capture an image of a press die area;
- an image extraction step of:
- extracting, from a group of still images forming the moving image data, a still image as a monitoring target image, in which a position of the slide and a movement direction of the slide are the same as the position of the slide and the movement direction of the slide detected from the still image selected in advance by a user, the movement direction of the slide being determined from the positions of the slide in the still images of frames before and after the still image, or
- comparing a reference monitoring area based on a state of the material to be processed selected in advance by the user or set automatically in a still image of the group of still images forming the moving image data with a reference monitoring area in a still image of a next frame and extract, as a monitoring target image, a matching still image;
- and
- an image monitoring step of performing image monitoring based on the monitoring target image and outputting a monitoring result.
