Definitions

  • a unit of a multiple-box seal for the entry of traveling strip into a vacuum chamber contains a cluster of three rolls journaled in the box, in parallel arrangement, two alongside one another and the third in the valley between the other two. Adjustable toggle linkages are provided for raising the middle roll against spring pressure so that slight clearance is provided for strip threaded between the rolls. Sealing blades engage the faces of the rolls and sealing shrouds the end-s of the rolls.
  • This invention relates to roll seals, and in particular, to seals of this type for limiting leakage into a vacuum processing chamber around strip traveling therethrough
  • Certain industrial processes such as coating by metalvapor deposition, must be conducted in a high-vacuum chamber. For continuous, high-speed operation this necessitates seals at the entrance to and exit from the chamber, through which the strip passes before and after treatment.
  • Conventional roll seals i.e. pinch roll-s tightly engaging the strip, are one form of such seal but, if the rolls are of metal, marring of the strip results. Rolls of a rubber-like material would avoid this difficulty but the temperatures of operation are too high for rubber to withstand.
  • I employ as a seal, a group or cluster of three chromium-plated rolls, one fitting in the depression between the other two, and lead the strip around the rolls successively in a sinuous path while maintaining a spacing between adjacent rolls slightly greater than the thickness of the strip.
  • Il also provide seals for the peripheries and ends of the rolls.
  • the only space left through which leakage may occur is the clearance between the strip and rolls and such leakage as occurs may readily be removed by pumping.
  • FIGURE l is a side elevation showing a series of seals according to my invention.
  • FlGURE 2 is a longitudinal vertical section through -a single roll-seat unit showing parts in elevation;
  • FIGURES 3 and 4 are full and partial cross sections, respectively, taken on the planes of lines lll-IH and lV-lV of FIGURE 2.
  • a complete seal for either the entrance or exit end of a vacuum strip-treating chamber comprises a plurality of roll-seal boxes 10, with spacer or separator boxes 11 therebetween.
  • a series of alternating-boxes and 11 tightly sealed together will be arranged in line with both the entrance to and the exit from the vacuum strip-treating chamber.
  • Each box is of ice plate construction, has one side removable to permit access to the interior, but tightly sealed, and openings 12 for the passage of strip in opposite ends.
  • the several boxes constituting a complete seal are tightly connected together in any convenient manner and the joints therebetween are sealed vacuum tight.
  • Each box has an exhaust outlet 10a or 11a connected to a suitable vacuum pump (not shown).
  • FIGURES 2-4 illustrate one of the roll-seal boxes in greater detail and the construction of the rol-l group or cluster disposed therein.
  • a housing 13 is disposed in each box 10 between spaced positioning rails 14 secured to the bottom of the box.
  • the housing consists of spaced parallel side plates 15 connected by cross bars 16.
  • a pair of spaced parallel rolls 17 and 18 have their shafts journaled in bearings 19 secured to plates 15 and extend substantially the full distance therebetween as shown in FIGURE 3.
  • a third roll 20 has its shaft journaled in vbearings 21 movable vertically in ways 22 secured to plates 1-5, which have slots to permit vertical adjustment of the roll shaft.
  • Rolls 17, 18 and 2d are chromium plated and polished.
  • Means are provided for adjusting roll 20 vertically in the form of toggle linkages 23, each including a nut 24 threaded on a screw shaft 25.
  • This shaft has portions near its two ends threaded in opposite directions so that on rotation thereof in one direction, the nuts will be drawn together raising bearings 21 while rotation in the other direction will move the nuts apart, lowering the bearings.
  • the linkages are pivotally connected to ears 23a depending from bearings 21 and t0 ears 2311 projecting from plates 15.
  • Compression springs 26 having adjustable back-up screws 27 engage hearings 21 and urge them downwardly to the limit permitted by the adjustment of nuts 2d. Screws 27 are threaded through lugs 28 projecting from plates 15.
  • Shaft 25 may be operated by a crank 25a journaled in a vacuum-tight bearing in a wall of box lil and connected to the shaft by a flexible joint 25h.
  • Entry and exit chutes 29 and 30 having a width equal to the length of the face of rolls 17, 1S and 20 are mounted Ibetween plates 15 and extend from the roll faces to flexible diaphrams 30a secured to the end walls of box 10, overlying openings 12 therein.
  • Sealing shrouds 3l recessed into the inner faces of plates 15 engage the sides of chutes 29 and 3l] and the ends of rolls I17, 18 and 20.
  • Each shroud is made up of a graphite plate or a layer of Teflon resin sheet 32 and is backed up by a leaf spring 33.
  • Chutes 29 and 30 are provided with recesses 29a for holding spring-urged sealing blades 37 of graphite. The blades engage the faces of rolls 17, 18 and 29.
  • the diaphrams permit contraction and expansion of chutes 29 and 3l) to allow for temperature changes.
  • rolls 20 are rst raised from the illustrated position by rotation of shaft 25, to facilitate threading the strip therebetween as indicated at S in FlGURE 1.
  • the rolls 20 are then lowered to positions in which they almost but not quite, pinch the strip against rolls 17 and 18. ln other words, a slight clearance, say .002, in excess of the ⁇ strip thickness is left between the rolls so they will not mar the product.
  • This clearance permits a slight leakage of air but such minor leakage as occurs may readily be handled by the vacuum pumps. All other spaces where leakage might occur are tight-ly sealed off.
  • the rolls 17, 18 and 2t? are driven by the frictional engagement thereof with ⁇ the advancing strip but the frictional drag imposed by the rolls is not suicient to cause slippage and marring of the strip.
  • sealing means are in the form of chutes carried by said box extending inwardly from said slots, and sealing blades on said chutes engaging the rolls.
