Abstract
The disclosure relates to a wood material panel pressing device for pressing a fibrous press cake in order to produce a wood material panel including an inspection device that is designed to emit a signal in the event of a disruption. According to the disclosure, the wood material panel pressing device for pressing a fibrous press cake for producing an HDF panel or an MDF panel includes: an inspection device, which is designed to emit a signal in an event of a disruption, wherein: the inspection device has a camera and an evaluation unit, the camera is arranged in an intake region of the wood material panel pressing device; and the evaluation unit automatically emits a signal in an event of a blow-out of press cake particles.
Claims26
A wood material panel pressing device for pressing a fibrous press cake for producing an HDF panel or an MDF panel comprising:
- (a) an inspection device, which is designed to emit a signal in an event of a disruption, wherein:
- (b) the inspection device has a camera and an evaluation unit,
- (c) the camera is arranged in an intake region of the wood material panel pressing device;
- and
- (d) the evaluation unit automatically emits a signal in an event of a blow-out of press cake particles.
A wood material panel pressing device for pressing a fibrous press cake for producing an HDF panel or an MDF panel, comprising:
- (a) an inspection device, which is designed to emit a signal in the event of a disruption, wherein:
- (b) the inspection device has a camera and an evaluation unit,
- (c) the camera is arranged in an intake region of the wood material panel pressing device;
- and
- (d) the evaluation unit is designed to automatically carry out a method featuring the steps:
- (i) continuous recording of images (B) of the intake region,
- (ii) continuous detection of measurement data for evaluation region pixels of the images (B), which belong to a predefined evaluation region of a surface of the fibrous press cake, such that evaluation data is obtained, wherein the evaluation data relate to a local height of the fibrous press cake and
- (iii) emission of a signal if the evaluation data indicate a change in the local height by more than a predetermined tolerance value (DT).
A method for monitoring a wood material panel pressing device for pressing a fibrous press cake to produce an HDF panel or an MDF panel, comprising:
- (i) continuous recording of images (B) of an intake region,
- (ii) continuous detection of measurement data for evaluation region pixels of images, which belong to a predefined evaluation region of a surface of the fibrous press cake, such that evaluation data is obtained, wherein the evaluation data relate to a spatially resolved height of the fibrous press cake, and
- (iii) emission of a warning signal if the evaluation data indicate a change in the height by more than a predetermined tolerance value (DT).
