Abstract

One or more actuator driven devices on a sheet forming machine receive power and engage in bi-didrectional communications with one or more quality control systems either by having no physically connected cables to transmit the power to the actuators and no physically connected cables used for the bi-directional communications; or contactless power and communication on a power cable; or a cable connected from the power source to the actuators to provide both power and bi-directional communications; or power is provided to the actuators by a cable and the bi-directional communications are wireless.

Description

    FIELD OF THE INVENTION
  • This invention relates to systems for controlling the cross-directional profile of sheet and web materials and more particularly to a cross-directional profile system that uses actuators and in which the power and/or communication to the actuators may be wireless or contactless and/or on the same cable.
  • DESCRIPTION OF THE PRIOR ART
  • It is well known that on-line measurements can be made to detect properties of sheet and web materials during manufacture thereof. For ease of description the term “sheet” is used herein including in the claims to refer to either a sheet or a web. Generally speaking, on-line measurements are made to enable prompt control of sheet and web making processes and, thus, to enhance sheet quality while reducing the quantity of substandard sheet material which is produced before undesirable process conditions are corrected. In the papermaking industry, for example, on-line sensors can detect variables such as basis weight, moisture content, caliper, coating weight, finish, color, and converting of paper sheets during manufacture.
  • To detect cross-directional variations in sheet materials, it is well known to use scanning sensors that travel back and forth across the sheet in the cross direction while detecting values of a sheet property along each scan. The term “cross direction” (or “CD”) refers to the direction across the surface of the sheet perpendicular to the machine direction, that is, the direction of travel of the sheet material.
  • Measurement information provided by the scanning sensors is assembled for each scan to provide a “profile” of the detected property of the sheet in the cross direction. Each profile thus comprises a succession of sheet measurements at adjacent locations or slices, the profile extending generally in the cross direction. From such profiles, cross directional variations in sheet properties can be detected. Based upon the detected cross directional variations, appropriate control adjustments can be made to the sheet making machine. Such adjustments are made by pluralities of cross directional actuators, such as motor driven slice lip profile control actuators located at the discharge of the headbox of a paper machine; inductive heaters for controlling the diameters of calender and/or other paper machine rollers along the length thereof; and coating blade actuators for controlling the CD weight profiles of coatings applied to one or both surfaces of the paper. Pluralities of cross directional actuators are also used in other industrial sheet forming processes such as plastic extrusion, metal rolling, etc.
  • As can appreciated in all of these sheet forming processes the actuators are used to adjust, flatten and shape the cross direction properties, such as density, moisture content, thickness, and optical properties, of the sheets that are being manufactured. In many cases these cross direction actuators will number from 20 to over 200 at one location on the sheet forming machine. There may be several actuator systems at various locations along the sheet formation process.
  • Most of these industrial sheet forming processes operate under severe environments that require actuator designs to be waterproof, corrosion resistant, vibration resistant, high temperature resistant, extremely reliable, as small as possible, and very easy to maintain and service. A critical and expensive portion of any actuator system is the power and communication distribution cables and connectors for the 20 to 200 actuator zones in a typical system extending across the sheet forming machine. Presently only special cables and sealed, industrially hardened, pinned connectors can be used to meet this requirement. Two examples of actuator systems that use power and communication distribution cables and connectors for the actuator zones are shown in U.S. Pat. Nos. 5,771,174 and 5,381,341.
  • Thus in order to substantially increase the reliability and serviceability of an actuator system it is desirable to either reduce the number of or eliminate the actuator system cables and connectors. Further reducing the number of or eliminating the actuator system cables and connectors will greatly reduce the cost of the system and the cost and time for system installation.
  • There is described in C. Apneseth et al, “Wireless—Introducing wireless proximity switches”, ABB Review 2/2002, pp. 42-49, a wireless proximity switch for use in a cell on an engine assembly line. As is shown in the figure on page 44, there is installed around the cell four primary loops that are fed by two power supplies that set up an alternating current in the loops to thereby produce a magnetic field throughout the cell. Inside the cell is a robot with several wireless proximity switches clustered at the robot gripper. The switches each have small coils that pick up the energy from the magnetic field and convert it to electric power. The switches each also have small radio transceivers and low power electronics that handle the wireless communication link between the switches and an input module outside of the cell. The switches communicate with the input module by way of antennas mounted in the cell.

  • DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
  • Referring now to FIG. 1, there is shown a typical papermaking machine 10 and various actuator driven profilers 12, 14, 16, 18, 20, 22, 24 and 26 that may be use on machine 10. More specifically, machine 10 as is well known to those of ordinary skill in the art will include an actuator driven dilution profiler 12 and an actuator driven slice profiler 14 associated with headbox 10 a. The headbox 10 a feeds a pulp suspension onto the initial part of a lower wire (not shown in FIG. 1). The actuator driven profilers 12 and 14 and others of the actuator driven profilers described herein are used to control the transverse profile of the suspension.
  • Papermaking machine 10 also includes a Fourdrinier table 10 b and a press section 10 c that may include one or more actuator driven steam profilers such as profiler 16 of FIG. 1. The moisture profile in the cross-machine direction (CD) is one of many important qualities of paper products. It is not only important that the overall moisture level be controlled, but also that the moisture distribution throughout the sheet be controlled both in the direction that the sheet is moving known as the machine direction (MD) and in the CD. Variation in moisture content of the sheet will often affect paper quality as much or even more than the absolute moisture content.
  • Steam showers profilers such as profiler 16 are conventional profiling systems that work by selectively delivering steam onto the paper web during production. Profiling steam showers deliver a variable distribution of steam in zones across the paper web. The amount of steam passing through each zone of a steam shower is adjusted through an actuator located in that zone.
  • Steam showers are widely used on the Fourdrinier table 10 b to help drainage and increase production. In the press section 10 c, steam is added before the press nips to increase the temperature of the web. The added temperature makes the water removal by pressing much more effective as the added moisture removal is much greater than the added moisture due to steam condensation.
  • Further downstream machine 10 may also include an actuator driven air water profiler 18, a calender profiler 20, a coat weight profiler 22, a finishing profiler 24 and an induction profiler 26. Profiling steam showers, such as calender profiler 20, are also used in the calendering process to improve gloss and smoothness of the paper products. Moisture spray systems, such as air water profiler 18, are also conventional profiling systems normally used in the evaporating sections of papermaking machines. The water spray systems are designed to apply a profile of moisture spray in the cross-machine direction to counter an undesirable moisture profile in the paper web. These systems consist of a series of flow-controlling actuators capable of independently adjusting the amount of spray in discrete adjacent zones in the CD. The induction profiler 26 is used for heating the paper roll to provide caliper and gloss control.
  • While FIG. 1 shows a papermaking machine 10 with various actuator driven profilers 12 to 26 it is well known to those of ordinary skill in the art that some of those actuator driven profilers may be used on special functions machines other than machine 10, such as a blade coater or a supercalender or a slitter winder, that are also associated with papermaking. This use is shown in block diagram form in FIG. 2.
  • As is shown in FIG. 2 one or more quality control systems (QCS) 30 a and 30 b are connected by suitable means 32 which may be a physical cable or a wireless connection as described below to a paper machine 34, a blade coater 36, a supercalender 38, one or more scanners 40 a and 40 b and a converter 42. Paper machine 34 may have edge control actuators and various actuator driven profilers such as the slice profiler, dilution profiler, steam profiler, air water profiler, coat weight profiler and induction profiler shown in FIG. 1. Blade coater 36 has an actuator driven coat weight profiler, supercalender 38 has actuator driven steam and induction profilers, and converter 42 has an actuator driven slitter winder.
  • In accordance with the various embodiments of the present invention described below the actuators of each of the one or more actuator driven profilers in papermaking machine 10 or the various actuators described in connection with the machines shown in block diagram form in FIG. 2 receive power and engage in bi-directional communications with the QCS system such as systems 30 a and 30 b of FIG. 2 as follows:
      • a. instead of a cable physically connected to the actuators to transmit power to the actuators and a cable physically connected to the actuators for bi-directional communication between the actuators and with the one or more QCSs 30 a, 30 b this embodiment uses as, is described below, a technique hereinafter referred to as “wireless” to transmit power to the actuators and to provide bi-directional communications between the actuators and with the one or more QCSs—alternatively this embodiment may use a closed magnetic path, hereinafter referred to as “contactless” to transmit power to each of the actuators—a subset of this embodiment is a cable physically connected between the one or more QCSs and the actuators for bi-directional communications between the actuators and wireless or contactless power;
      • b. contactless power and communication on a power cable;
      • c. a cable physically connected from the power source to the actuators to provide power to the actuators and bi-directional communication between the one or more QCSs and the actuators using the power cable;
      • d. power provided to the actuators through a power cable physically connected to each of the actuators and wireless communication.
  • Referring now to FIG. 3 there is shown in simplified block diagram form the embodiment where no cables are physically connected to the actuators are used to transmit power to the actuators and no cables are physically connected to the actuators are used for bi-directional communication between the actuators and one or more QCSs.
  • The embodiment shown in FIG. 3 uses a technique referred to as “wireless” for both the transmission of power and the bi-directional communications and thus the embodiment as a whole is said to be wireless.
  • Bi-directional communication with one or more QCSs such as QCS 30 a and/or QCS 30 b of FIG. 2 takes place through a primary signal antenna 44 which is in close proximity to the array 46 of actuators 46 a, 46 b, 46 c . . . 46 n and by an antenna (not shown in FIG. 3) which is located in each of the actuators. The primary signal antenna 44 interfaces with the one or more QCSs through a signal drive antenna module 48. Power is transmitted to each of the actuators 46 a to 46 n from power drive module 49 by a transformer arrangement where the secondary side of the transformer is embedded in each actuator 46 a to 46 n and the primary side 47 of the transformer is located outside of the actuator.
  • Alternatively as is shown in FIG. 3 a, a closed magnetic path may be used to transmit power to each of the actuators by using small ring types cores 45 that consist of two half circle parts 45 a and 45 b. One of the half circle parts carries the secondary winding 45 c and the half circle parts can be clipped together around the primary coil wire 45 d. The arrangement shown in FIG. 3 a uses a technique referred to as “contactless” for the transmission of power.
  • Therefore the embodiment shown in FIG. 3 is wireless as to both transmission of power and bi-directional communications and the embodiment of FIG. 3 a is wireless as to bi-directional communications and contactless as to the transmission of power as in both embodiments power supplied to and bi-directional communication with each of the actuators 46 a to 46 n does not require the physical connection of a communication cable and a power cable to each of the actuators as in the systems of the prior art.
  • A subset of the embodiment shown in FIG. 3 is where the power is supplied to each of the actuators in the wireless or contactless manner shown in FIGS. 3 and 3 a and the bi-directional communications between the one or more QCSs and the actuators is accomplished through a cable that is connected to each actuator as is shown in the aforementioned U.S. Pat. Nos. 5,771,174 and 5,381,341 the disclosures of which are hereby incorporated herein by reference.
  • Referring now to FIG. 4 there is shown in simplified form an embodiment for the present invention wherein power is supplied to all of the actuators and bi-directional communication between the one or more QCSs and all of the actuators are both accomplished in a contactless manner over a power cable. The simplified diagram of FIG. 4 shows a single actuator such as for example actuator 46 a of FIG. 3 which has included therein a part of a magnetic core 50 that may be made from ferrite or a similar material with a wire 52 wound on the core. The actuator also includes a modulator/demodulator 54.
  • External to and not connected to the actuators is a power and communication cable 56. At that end of the system not shown in FIG. 4 where the one or more QCSs are located and the system for providing power to all of the actuators is also located a modulator/demodulator (not shown in FIG. 4) that modulates the AC signal on the power and communication cable 56 to provide communication to all of the actuators and demodulates the communication signals modulated on the AC power signal at the actuators to receive communications from the actuators.
  • As is shown in FIG. 4, the communication and power cable 56 includes adjacent to each actuator a magnetic core 58 that may be made from ferrite or a similar material which core in combination with the magnetic core 50 embedded in each actuator forms a transformer that allows the modulated AC power signal on cable 56 to be received and demodulated by each actuator. Thus the embodiment shown in FIG. 4 is also contactless as power supplied to and bi-directional communication with each of the actuators such as actuators 46 a to 46 n of FIG. 3 does not require the physical connection of a communication cable and a power cable to each of the actuators as in the systems of the prior art.
  • Referring now to FIG. 5, there is shown in simplified form an embodiment 60 for the present invention wherein a cable 62 is physically connected from the source of power to each of the actuators 64 a, 64 b, 64 c in a manner well known in the art to provide power to all of the actuators and the bi-directional communications between the actuators and the one or more QCSs also occurs using cable 62. Each actuator 64 a, 64 b, 64 c includes an associated embedded modulator/demodulator 66 a, 66 b, 66 c for bi-directional communications over cable 62 with the one or more QCSs.
  • Upstream from the actuators 64 a, 64 b and 64 c is a power and communications module 68 that includes a modulator/demodulator (not shown in FIG. 5) that allows power to be transmitted over cable 62 to each of the actuators and the cable to also carry the bi-directional communications between the actuators and the one or more QCSs.
  • Referring now to FIG. 6, there is shown in simplified form an embodiment 70 for the present invention wherein power is provided to each of actuators 72 a, 72 b . . . 72 n over a cable 74 that is physically connected by associated connector 76 a, 76 b . . . 76 n to each of an associated one of the actuators in a manner well known in the art. A power drive module 78 provides the power to cable 72.
  • Bi-directional communication between each of the actuators 72 a, 72 b . . . 72 n and the one or more QCSs is provided wirelessly by the antenna system described above for the embodiment shown in FIG. 3. As previously described a signal drive antenna module 80 is connected between the one or more QCSs and the communication antenna 82. Antenna 82 is in close proximity to each of the actuators 72 a, 72 b . . . 72 n and each of the actuators include an antenna.
  • While the present invention is described herein in connection with a paper making machine it should be appreciated that the present invention in all of the embodiments described herein can be used with any process that uses actuators in connection with a moving sheet or web. Examples of such processes are the forming of textiles and machines that printing on sheets or webs.
  • It is to be understood that the description of the preferred embodiment(s) is (are) intended to be only illustrative, rather than exhaustive, of the present invention. Those of ordinary skill will be able to make certain additions, deletions, and/or modifications to the embodiment(s) of the disclosed subject matter without departing from the spirit of the invention or its scope, as defined by the appended claims.
