Definitions

  • the present invention relates to method and apparatus for cleaning particles from a substrate; more particularly, to method and apparatus for cleaning particles from the surface of a process roller; and most particularly, to method and apparatus for cleaning particles from a roller surface by contact with an adhesive-covered tape which may be rewound for repeated use.
  • Adhesive-covered tape (referred to herein for simplicity as "adhesive tape) as used in the prior art can be an expensive medium for removing particles from a substrate, as the adhesive capabilities of the tape typically are far from exhausted in prior art applications.
  • cleaning of relatively wide rollers by tape requires either an equivalents wide adhesive tape, which is very costly, or the progression of a narrower tape element along the surface to be cleaned.
  • the operation of prior art systems for using and renewing adhesive tape cleaners is highly labor-intensive, requiring that an operator be present to remove the length of spent tape and establish a fresh tape adhesive surface on the surface to be cleaned. See, for example, U.S. Patent No. 6,196,128 B1. What is needed in the art is a method and apparatus for increasing the utility of adhesive tape for cleaning by reusing a tape element in a controlled, predictable, and automated way.
  • a cleaner assembly for cleaning a roller comprises a tape unwinder for holding and dispensing adhesive tape.
  • the adhesive tape may be a continuous strip or may comprises discrete sheets of adhesive tape wound on top of each other.
  • the tape roll is held in place by a spring-loaded gudgeon and by a drive having a one-way clutch that free-wheels in the tape forward direction but engages in the reverse direction.
  • a tape winder is similarly equipped except that it winds in the forward direction and free-wheels in the reverse direction.
  • the two drives are connected by a timing belt that also includes a motorized drive pulley.
  • a length of tape may be wound back and forth between the unwinder and the winder by alternating the rotation of the drive.
  • the tape is wound with its adhesive side out and may be passed around a backing roller (although not necessarily) for pressing the tape against a substrate to be cleaned. Pressure of the backing roller may be varied.
  • a tach sensor at the backing roller tracks the length of tape passed in either direction.
  • the cleaning head may be mounted on a rail for axial movement such that a substrate, such as a roller longer than the width of the tape, may be cleaned by moving the head in discrete stages along the roller.
  • the tape roll comprises a plurality of discrete lengths of tape, herein referred to as "sheets", wound on top of each other.
  • sheeted tape roll Such a tape roll is referred to herein as a “sheeted tape roll”.
  • the outer sheet has an end exposed, and the tape roll is rotated against the substrate to be cleaned in a direction such that the exposed end is trailing.
  • the tape roll is impinged against a continuous tape roll such that the outer sheet adhering the transferred particulates is transferred to the continuous tape roll, exposing a fresh sheet on the sheeted tape roll which is then ready for renewed cleaning service.

  • the prior art as exemplified in U.S. Patent Nos. 4,009,047 and 6,196,128, and U.S. Patent Application Publication No. U.S. 2006/0057322 A1 , does not suggest or disclose to use an adhesive tape surface for more than one pass in contact with a substrate to be cleaned, such as a process roller or CCR.
  • Such repeated usage in accordance with the present invention can greatly reduce the cost of operating roller cleaning systems wherein a CCR is cleaned by being brought into contact repeatedly with a length or circumference of adhesive tape.
  • CCR 12 is in nipped contact with a web substrate 14 wrapped around a backing roller 16 and moving in a direction 18 such that CCR 12 rotates clockwise 20 as shown.
  • CCR 12 removes particulate contamination from the surface of web substrate 14 and transfers such contamination onto the surface of CCR 12 in known fashion.
  • CCR 12 is also known in the art as a "particle transfer" roller, the surface of which typically is formed of a triboelectric material such as polyurethane or silicone rubber which attracts particles with a greater force than the surface of web substrate 14.
  • CCR 12 or any other type of process roller, must be cleaned of accumulated particulate debris from time to time, to maintain a healthy process.
  • the particle removing effectiveness of the roller tends to diminish as the roller surface accumulates particles.
  • Prior art system 10 renews the surface of CCR 12 by removing accumulated particles therefrom.
  • System 12 comprises a secondary CCR 22 may be similar to the surface of primary CCR 12, in that it may be formed of a resilient polymer having a high surface energy such as polyurethane, silicone rubber, butyl rubber, neoprene, or the like, or it may be formed of a tacky polymer such as a tape adhesive; for example, CCR 22 may comprise a multiple-convolution roll of adhesive tape wound on a core with the adhesive side facing outwards.
  • a suitable tape for example, is "Scotch Brand Tape No. 850" available from 3M Corporation, St. Paul, Minnesota, or its equivalent.
  • Prior art system 10 further comprises mounting means 24 for supporting CCR 22.
  • Mounting means 24 is slidably disposed on a vertical guide 26 for variable vertical actuation thereof by a controllable linear solenoid actuator 28.
  • System 10 is mounted via a bearing element 30 on a track 32 for traversing secondary CCR 22 across the surface of primary CCR 12 in an axial direction thereof, either continuously or intermittently at a sequence of axial positions.
  • Secondary CCR 22 is not powered for rotation but rather is rotated along the surface of primary CCR 12 by frictional contact therewith.
  • an operational disadvantage of prior art system 10 is that operator involvement is frequent, either to wash secondary CCR 22 as it gets dirty, when the surface is a triboelectric polymer; or to remove an outer convolution of adhesive tape, when CCR is an roll of adhesive tape, when the adhesive surface becomes loaded with particles removed from primary CCR 12.
  • roller cleaning systems wherein the primary CCR is cleaned by being brought into contact repeatedly with a length or circumference of adhesive tape.
  • Sheeted tape roll 122 comprises a conventional roll core 140 with individual adhesive sheets 142, 144, 146 removably attachable around the circumference of the roll core 140 superimposed onto one another.
  • the roll core 140 has an attachment means which may be an adhesive coating to allow the first individual adhesive sheet 142 to be removably attachable around the circumference of the roll core 110.
  • the individual adhesive sheets 142, 144, 146 have an adhesive surface 148a-c facing outwardly, and have a non-adhesive surface facing inwardly.
  • the individual sheets can be rolled such that the adhesive surfaces are facing inwardly and the non- adhesive surfaces are facing outwardly.
  • the sheeted roll 122 is formed by attaching a first end 150 of the first sheet 142 onto the roll core 140 and wrapping the first sheet 142 around the circumference of the roll core 140.
  • the other end 152 of the first sheet 142 will overrun first end 150 by virtue of first sheet 142 being greater in length than the circumference of the roll core 140.
  • the end 152 is removably attached onto end 150 by the adhesive surface 148a of the first sheet 142.
  • a second sheet 144 is then wrapped around the outer circumference of the first sheet 142 with end 154 of the second sheet 144 being abutted to end 152 of the first sheet 142.
  • the term abutted is to be understood to include being adjacent to, as there may be a gap between successive sheets.
  • the adhesive surface 148a of the first sheet 142 will securely hold in place the second sheet 144.
  • a third sheet 146 is then wrapped around the outer circumference of the second sheet 144 with end 158 of the third sheet 116 being abutted to end 156 of the second sheet 114.
  • the adhesive surface 148b of the second sheet 144 will securely hold in place the third sheet 146.
  • further individual adhesive sheets are abutted to end 160 of the third sheet 146 and so on until the roll core 140 is "full". It will be realized that because the sheets 142, 144, 146 are all of the same length, the overrun or circumferential offset of the respective ends 152, 156, 160, and so on, will decrease as the roll core 140 becomes "full". The length of each sheet can however be adjusted as desired or required.
  • the roll core 140 is positioned such that the outermost sheet of sheeted roll 122 is positioned in contact at a point 164 with the cleaning surface 166 of CCR 12.
  • impurities located on the cleaning surface 166 will be transferred to the adhesive surface of the outer sheet of sheeted tape roll 122.
  • the adhesive surface of the outer sheet becomes contaminated, replacement is achieved simply by peeling the contaminated sheet away by virtue of lip 162, thus leaving behind a clean sheet to be applied to the cleaning surface 166 of the cleaning roll 12, until that sheet too needs replacement, and so on.

Because motor 278 is reversible, the tape web may also be driven in the reverse direction from spindle 272b onto spindle 272a, in accordance with the present invention.
  • a currently-preferred method for cleaning a roller such as a CCR 12 comprises the minimum steps of: a) engaging the tape web with the CCR surface by advancing the backing roller (CCR is in idler mode); b) passing a predetermined first length (preferably 48 inches, as measured by tach sensor 285 and length counter 287) of tape over the CCR surface between the unwinder spindle and the winder spindle to clean the CCR surface a first time; and c) rewinding the length of tape onto the unwinder spindle to clean the CCR surface a second time.

  • the tape length may be further re-used until it fails to adequately remove particles from the surface to be cleaned.
  • the roller may be cleaned in successive stages by moving the tape to successive cleaning positions along the roller, in accordance with the following process steps: a) retracting the CCR from a substrate it has been cleaning (CCR is in idler mode); b) advancing the cleaning system to a first cleaning zone on the CCR; c) engaging the tape with the CCR surface by advancing the backing roller; d) passing a predetermined first length (preferably 48 inches) of tape over the CCR between the unwinder spindle and winder spindle to clean the first cleaning zone a first time; e) rewinding the first length of tape onto the unwinder spindle to clean the first zone a second time; f) retracting the backing roller and tape from the CCR surface; g) re-advancing the tape to place the first predetermined length of tape permanently on the winder spindle; h) moving the cleaning system to the next cleaning zone on the CCR (which preferably overlaps slightly

Abstract

L'invention concerne un ensemble de nettoyage permettant de nettoyer un rouleau comprenant un dérouleur et un enrouleur de bande destinés à maintenir et à distribuer un ruban adhésif qui peut être une bande continue ou qui peut comprendre des feuilles de ruban adhésif enroulées les unes sur les autres. L'enrouleur et le dérouleur sont reliés à un entraînement par une courroie crantée. Ainsi, un ruban peut être enroulé et déroulé sur une surface de rouleau en alternant la rotation de l'entraînement. Le ruban est passé autour d'un rouleau de soutien afin de comprimer le ruban contre un rouleau à nettoyer. Dans un second mode de réalisation, le rouleau de rubans comprend une pluralité de feuilles de ruban enroulées les unes sur les autres. Pour enlever une feuille extérieure usée, la feuille extérieure porteuse des particules transférées est transférée sur un rouleau de rubans, de façon à laisser à découvert une nouvelle feuille sur le rouleau de rubans en feuille, lequel est alors prêt pour un nouveau service de nettoyage.
