Monitoring system, control system, and actuation assembly of a paper machine
A monitoring system comprising: (a) one or more sensors that monitor activity, amplitude, size, scale, duration of activity or a combination thereof of stock on a paper machine and (b) a control system in communication with the one or more sensors and one or more foil sections within the paper machine; wherein the control system measures the activity, amplitude, size, scale, duration of activity or a combination thereof of the stock and correlates the activity, amplitude, size, scale, duration of activity or a combination thereof to formation of fibers within the stock so that an angle, height, or both of the one or more foil sections are adjusted to change the activity, amplitude, size, scale, duration of activity or a combination thereof in the stock.
1. A monitoring system comprising:
a. one or more sensors that monitor activity of stock on a paper machine and
b. a control system in communication with the one or more sensors and one or more foil sections within the paper machine;
wherein the control system is configured to measures the activity of the stock and is configured to correlates the activity to formation of fibers within the stock so that an angle, a height, or both of the one or more foil sections are adjusted to change the activity of the stock; and
wherein the one or more sensors are one or more low angle sensors that are located along a side of the paper machine and monitor the paper machine in a direction substantially parallel to a wire on the paper machine and the one or more low angle sensors measure the amplitude of the stock.
2. The monitoring system of claim 1 , wherein the activity is amplitude, size, scale, duration of activity, or a combination thereof in a predetermined region relative to the one or more foil sections.
3. The monitoring system of claim 1 , wherein the one or more low angle sensors are a plurality of low level sensors that are located between a head box and a couch roll of the paper machine.
4. The monitoring system of claim 3 , wherein the plurality of low level sensors have at least a portion that is coplanar with the wire of the paper machine.
5. The monitoring system of claim 1 , wherein the one or more sensors are one or more high angle sensors, and the one or more high angle sensors are located at an angle relative to the wire of the paper machine.
6. The monitoring system of claim 5 , wherein the angle is about 90 degrees or less and about 15 degrees or more.
7. The monitoring system of claim 1 , wherein the one or more sensors are ultrasound, infrared, CMOS sensor, charge-coupled device, matrix camera, area scan camera, line scan camera, microwave, a temperature sensor, nuclear, capacitance, pressure, vacuum, or a combination thereof.
8. The monitoring system of claim 1 , wherein the monitoring system monitors a stock jet out of a head box, a location of a forming board, a location of the forming board relative to the head box, an angle of the stock jet, an impingement angle of the stock jet relative to the wire, a cut through, a forming shower, or a combination thereof.
9. The monitoring system of claim 1 , wherein the monitoring system measures an amount of water removed from the stock before a forming board, at each foil in the one or more foil sections after the forming board, or both.
10. A monitoring system comprising:
a. one or more sensors that monitor activity of stock on a paper machine and
b. a control system in communication with the one or more sensors and one or more foil sections within the paper machine;
wherein the control system is configured to measures activity of the stock and is configured to correlates the activity to formation of fibers within the stock so that an angle, a height, or both of the one or more foil sections are adjusted to change the activity of the stock; and
wherein the monitoring system includes a level device, and the one or more sensors that measure the activity of the stock, which is an amplitude of the stock above an activity line formed by the level device; and
wherein the activity, amplitude, size, scale, duration of activity or a combination thereof of the stock in a predetermined area is a density of bright spots, a number of dimples, or both captured by the one or more sensors in the predetermined region.
11. The monitoring system of claim 10 , wherein the one or more sensors are ultrasound, infrared, CMOS sensor, charge-coupled device, matrix camera, area scan camera, line scan camera, microwave, a temperature sensor, nuclear, capacitance, pressure, vacuum, or a combination thereof.
12. The monitoring system of claim 10 , wherein the monitoring system monitors a stock jet out of a head box, a location of a forming board, a location of the forming board relative to the head box, an angle of the stock jet, an impingement angle of the stock jet relative to a wire, a cut through, a forming shower, or a combination thereof.
13. The monitoring system of claim 10 , wherein the monitoring system measures an amount of water removed from the stock before a forming board, at each foil in the one or more foil sections after the forming board, or both.
