Abstract
An apparatus for coating a workpiece that consists at least in sections of wood, wood-based material, synthetic material or the like. The apparatus can include a pressing device for pressing a coating material onto a surface of the workpiece to be coated, a conveying device for inducing a relative movement between the workpiece and the pressing device, an activation device for activating a joining agent used for joining the coating material to the surface of the workpiece to be coated, and a sensor for detecting an operating variable of the joining agent. The apparatus can include a shielding device for shielding a sensor section of the sensor.
Claims12
An apparatus for coating a workpiece comprising wood, wood-based materials, or synthetic material, the apparatus comprising:
- a pressing device for pressing a coating material onto a surface of the workpiece to be coated;
- a conveying device for inducing a relative movement between the workpiece and the pressing device;
- an activation device for activating a joining agent used for joining the coating material to the surface of the workpiece to be coated;
- a temperature sensor for detecting a temperature of the joining agent, the temperature sensor being configured to send or receive a sensor signal for detecting the temperature;
- and
- a shielding device for shielding a sensor section of the temperature sensor, the shielding device being at least partially integrated into the activation device;
- wherein:
- (i) the activation device comprises a barrier fluid outlet to dispense barrier fluid for shielding the sensor section, and
- (ii) the apparatus further comprises a deflection device for deflecting the sensor signal, further wherein (a) the deflection device comprises a reflective element and/or (b) the deflection device comprises a signal guiding element.
A method for coating a workpiece comprising wood, wood-based materials, or synthetic material, using an apparatus,
- said apparatus comprising:
- a pressing device for pressing a coating material onto a surface of the workpiece to be coated;
- a conveying device for inducing a relative movement between the workpiece and the pressing device;
- an activation device for activating a joining agent used for joining the coating material to the surface of the workpiece to be coated;
- a temperature sensor for detecting a temperature of the joining agent, the temperature sensor being configured to send or receive a sensor signal for detecting the temperature;
- and
- a shielding device for shielding a sensor section of the temperature sensor, the shielding device being at least partially integrated into the activation device;
- wherein:
- (i) the activation device comprises a barrier fluid outlet to dispense barrier fluid for shielding the sensor section, and
- (ii) the apparatus further comprises a deflection device for deflecting the sensor signal, further wherein (a) the deflection device comprises a reflective element and/or (b) the deflection device comprises a signal guiding element;
- and
- said method comprising the steps of:
- activating the joining agent used for joining the coating material onto the surface of the workpiece to be coated by means of the activation device;
- detecting the temperature of the joining agent using the temperature sensor;
- comparing the detected operating variable with a target operating variable of the joining agent;
- and
- adjusting at least one operating parameter by means of the activation device, in order to bring the detected operating variable closer to the target operating variable.
