Definitions

  • ABSTRACT Apparatus for removing and collecting dust from a travelling sheet or web of material including a blow box having means for impinging jets of clean air against the sheet in directions both in the direction of travel of the sheet and opposite thereto.
  • a suction box cooperates with the blow box to form suction gaps withdrawing the air after its engagement with the material to thereby remove the dust from the material.
  • the suction in the suction box is sufficient to withdraw additional air from the surrounding atmosphere through the spaces which exist between the material and the suction box, and means is provided to remove the dust from the air withdrawn by the suction box.
  • An alternate embodiment -provides guide elements in the suction gaps which support the material at these points through a film of air.
  • the present invention relates to apparatus for removing and collecting dust from the surface of a sheet or web of material such as paper and the like.
  • the invention has particular application to material which is sensitive to the touch such as materials which have coatings or a surface texture which may be damaged if it rubs against the apparatus as it is advanced therethrough.
  • the present invention utilizes principles disclosed in U. S. Pat. No. 3,231,165 issued Jan. 25, 1966, wherein oppositely-directed jets of gaseous medium are impinged against a travelling web to stabilize the travelling material against fluttering as it is treated by the gaseous medium.
  • the present invention provides apparatus for sucking the dust off from the web or sheet and simultaneously stabilizing the web or sheet spaced from the stationary apparatus at the optimum distance for achieving the best possible dust removal effect.
  • the primary object of the invention is characterized by a blow box having at least one row of blow jets, preferably openings of the eyelid type, extending transverse to the path of travel of the material.
  • the openings are disposed within a fixed wall parallel to and adjacent the path of the material.
  • the blow box is connected with means for supplying clean air at a sufficient quantity to blow jets of air between the material and the fixed wall substantially parallel to the direction of motion of the material so as to impinge against the material with a scrubbing effect. Removal of the dust is effected by a suction box having a suction gap parallel with the blow openings immediately adjacent the blow box to thereby achieve effective dust removal in combination with an effective stabilization of the material at the proper spacing relative to the fixed plane.
  • the present invention provides blow openings to project the jets of air both in the direction of motion of the material and in the direction opposite thereto and the suction gaps are disposed both in advance and behind the blow box.
  • means is provided to admit atmospheric air into the suction boxes in amounts regulated to insure non-engagement of the travelling material with the stationary parts of the suction and blow boxes and to provide a film of air which 2. separates the film from the fixed elements of the apparatus.
  • FIG. 1 is a longitudinal sectional view along the direction of travel of the material illustrating the blow box and suction box in cross section as seen from the line l--l of FIG. 2;
  • FIG. 2 is a plan view illustrating the blow openings and suction gaps as seen from the line 2-2 in FIG. 1;
  • FIG. 3 is a view partially in section illustrating the combined blow box and suction box and the respective connections to sources of pressure and suction, including the means to collect the dust removed from the material;
  • FIG. 4 is a view similar to FIG. 1 illustrating the modified embodiment of the combined blow box and suction box made in accordance with the invention.
  • the material 1 to be cleaned of dust may consist of a continuous web of material being advanced as indicated by the arrow la along a predetermined path of travel.
  • the material may also be individual sheets which are fed along the path of movement.
  • a fixed wall 2 is disposed parallel to and adjacent the path of movement of the material 1 so as to be disposed in confronting relation with the surface of the web or sheets transported therein.
  • the wall is provided with means for projecting jets of clean air against the confronting surface of the material, in the present instance three rows of .blow openings 3 which extend transverse to the web 1.
  • the blow openings 3 located in the outermost rows 3a blow air jets between the web and the fixed wall substantially parallel to the direction of motion of the web, thereby to position the web in the predetermined path of travel.
  • the blow openings 3 in the row 3b between the outermost rows 30 are adapted to eject air jets in directions having a greater inclination to the web than the first mentioned jets so as to penetrate into the surface layer of the web and release dust therefrom, thereby contributing to an improvement of the dust removal effect.
  • the openings in the row 3b are alternately turned in opposite directions parallel to the travel of the web, blowing jets both in the direction of travel and oppositely thereto.
  • the blow openings 3 in the wall 2 are in communication by way of a blow box 4 with air supply means operable to supply pressurized clean air to the blow box.
  • the connection is by way of a duct 12 to a blower 13 having a motor 14 and a pressure regulator 15in the suction side of the blower.
  • the pressure regulator 15 has an operator 16 to adjust the pressure and quantity of the clean air supplied to the blow box 4. In this manner, jets of pressurized clean air are impinged against the confronting surface of the material 1 and the dust in the surface layer is removed by the parallel flow of clean air generated by the rows 3a between the wall- 2 and the material 1.
  • suction gaps 5 are provided on both sides of the fixed wall 2, as seen in the direction of motion of the material, The suction gaps 5 are defined between the leading and trailing ends of the fixed wall 2 and upstanding walls 7 of a suction box 6 which surrounds the blow box 4 and is in communication with a source of suction.
  • the suction box is connected by ductwork 17 to a filter 18 having removable filter cartridges 19 therein. Air is drawn through the filter 18 by a blower 23 having a motor 24 and a pressure regulator 25 with an operator 26. Thus operation of the blower 23 withdraws the dust-laden air from between the wall 2 and the material 1 into the filter 18 where the dust particles are collected, for example by the cartridges 19.
  • the wall 2 along its edges adjoining the suction gaps 5, is beveled as indicated at 2a at approximately to facilitate the deflection of air and dust into the suction gaps.
  • the walls 7, in the illustrated embodiment may be raised and lowered to adjust the distance between the upper edge of the wall and the material in accordance with the flow of air and the character of the material.
  • the suction provided by the blower 23 operates to withdraw a greater quantity of air than is supplied by the blower 13 so that substantially all of the air impinged against the web from the openings 3 is drawn into the suction gap along with atmospheric air from the other side of the upright walls 7.
  • the flow of air over the tops of the walls 7 is facilitated by the inturned lips 27 on the walls.
  • the flow of air forms a cushion which resists displacement of the material into scraping engagement with the wall 7, thereby avoiding the possibility of damage to the material from such engagement, for example when the character of the surface of the web is sensitive to the touch, as, for example, undried coatings.
  • the material is conveyed in its path of travel substantially free from fluttering.
  • the form of the openings 3 insures the scrubbing action of the air jets impinging against different spots of the travelling material surface, thereby scrubbing the surface free from lint and dust and simultaneously conveying the lint and dust away from the surface.
  • FIG. 4 a modified embodiment of the invention has been provided, as shown in FIG. 4.
  • the blow box 4a and its connection to the pressurized clean air is identical to the blow box 4.
  • the suction box 36 has been modified as indicated but its connection to the suction and collecting arrangement is identical to the previously-described em- I bodiment, as indicated at 17a.
  • the suction box 36 is provided with upstanding adjustable walls 37 which terminate at their upper extremities in outturned lips 38.
  • the lips 38 cooperate with guiding means 39 in the form of fixed tubes or bars extending transversely with respect to the direction of movement of the material.
  • the guide elements 39 are preferably circular in cross section and are not mounted for rotation. Their position overlying the suction gap 35 between the blow box 4a and the wall 37 generates a film of air indicated at 40 between the guiding means 39 and the material. This film of air separates the material from the guiding means and is effective to lubricate the material passing the guiding means.
  • the guiding means 39 also serve to deflect a major portion of the air discharged from the space between the blow box 4a and the material into the suction gap 35 so as to avoid any tendency of the major part of the air to follow along the path of movement of the material.
  • the outturned lips 38 cooperate with the guiding means 39 to facilitate the injection of atmospheric air into the suction box to insure against discharge of dustladen air into the surrounding atmosphere.
  • the walls 37 are adjustable similarly to the walls 7 of the previous embodiment for the same purpose.
  • An advantage for the embodiment of the present invention is that due to the stabilizing effect of the jets of the used gaseous medium there is no need for a stretching of the web, even if the material of the web is thin and very fragile, for instance consists of tissue.
  • Apparatus for sucking dust from horizontally traveling material in sheet or web form by simultaneously blowing on clean air and sucking off dust-laden air adjacent the surface of the material comprising a suction box extending across the width of the material in its path of travel, a fixed wall substantially parallel to and adjacent the path of travel of the material, said wall being coextensive in length with said box and cooperating with said box to provide at opposite sides of said wall suction gaps extending across said path of travel, said fixed wall having at least three rows of blow openings for blowing jets of clean air between the path of travel and the fixed wall, said rows being parallel to said suction gaps, said jets having their horizontal components substantially parallel to the wall and to the direction of motion of said sheet, said jets being directed in opposite directions concurrent and countercurrent to the direction of travel of the material respectively, the jets in the two outermost of said rows having a minimum vertical component to blow jets of air substantially parallel to the direction of motion of the material, the jets in the central row having a sharp angular vertical component to project jets
