Abstract
A mold monitoring apparatus for an injection molding machine captures an image of a cavity portion of an opened mold, and determines the state of the cavity portion by means of image processing. The apparatus includes a light emitting unit, an image capturing unit, and an image processing unit. The light emitting unit projects onto the cavity portion light rays other than visible light rays. The image capturing unit includes an image sensor for capturing reflection light rays that travel from the cavity portion to the image sensor via a filter for blocking visible light rays. The image processing unit determines the state of the cavity portion on the basis of an image signal output from the image sensor and through image processing.
Claims17
A mold monitoring apparatus for an injection molding machine, comprising:
- a light emitting unit configured to project light rays other than visible light rays onto a cavity portion of an opened mold;
- an image capturing unit including an image sensor configured to capture reflection light rays that travel from the cavity portion to the image sensor via a filter configured to block visible light rays;
- and an image processing unit configured to determine a state of the cavity portion on the basis of an image signal output from the image sensor and through image processing,
- wherein the image capturing unit captures regular reflection light from the cavity portion,
- wherein the image signal includes a plurality of pixels,
- wherein the light emitting unit is attached to a first side surface of the stationary platen of the mold clamping apparatus,
- wherein the image capturing unit is attached to a second side surface of a stationary platen of a mold clamping apparatus, and
- wherein the image capturing unit includes a support mechanism attached to the second side surface of the stationary platen and having a position adjustment section for adjusting the position of a main body of the image capturing unit along a longitudinal direction of the image capturing unit.
A mold monitoring apparatus for an injection molding machine, comprising:
- a light emitting unit configured to project light rays other than visible light rays onto a cavity portion of an opened mold;
- an image capturing unit configured to capture reflection light rays that travel from the cavity portion to the image capturing unit via a filter configured to block visible light rays;
- and
- an image processing unit configured to determine a state of the cavity portion based on an image signal output from the image capturing unit,
- wherein the light emitting unit includes an adjusting mechanism configured to change an angle that the light rays are projected onto the cavity portion of the opened mold, and
- wherein the image capturing unit includes a first adjusting mechanism configured to adjust the image capturing unit along a longitudinal direction thereof so as to be moved forwards or backwards relative to the cavity portion of the opened mold, and includes a second adjusting mechanism configured to adjust a capture angle of the image capturing unit.
