Definitions

  • ABSTRACT Granules are placed in a hopper having a resilient seal surrounding a bottom outlet under which rotates the periphery of a roll having a cavity for receiving a preselected quantity of such granules each time the cavity passes under such outlet.
  • the cavity roll in turn drives a belt carried by idler rolls located so that the belt contacts the cavity roll directly after the periphery of such roll leaves the hopper outlet seal, and such contact continues until the belt reaches the bottom of the roll, where a horizontal reach of the belt carries the granules to a discharge station above a distribution roll. From such distribution roll the granules fall under a gate onto a sheet of roofing material which moves horizontally thereunder.
  • GRANULE APPLICATOR This invention relates to granule applicators, and more particularly to apparatus for applying granular material to sheets of roofing material.
  • Known devices for applying granules to roofing sheets involve mechanisms which apply a pattern by starting and stopping means, or reciprocating means which respond to signals. This requires undesirable acceleration and deceleration of the equipment causing wear and tear due to the forces set up thereby. Also, such equipment comprises complicated clutches, brakes, cam switches, or other sequencing mechanism, that require expensive and continuous maintenance, because of clutch and brake slippage, variations in the operative sequence, etc., to keep the selected pattern uniform.
  • the present invention comprises means for metering a measured quantity of granular material and applying this material to a moving sheet or surface
  • the granular material is applied to the sheet or surface in an evenly distributed layer, and in a predetermined sequence and in registration with the sheet.
  • This invention avoids difficulties with maintaining patterns at varying machine speeds, since it is continuous in operation and has no need for brakes, clutches or other components to provide intermittent operation to start and stop the granule drop.
  • the invention provides a granule applicator unit in which a granule hopper is located well above a horizontalpath along which the sheet moves continuously during the application of granules thereon.
  • a cavity roll is located directly under the hopper, and drives a belt that is carried by idler rolls.
  • One ofthe idler rolls is located above the cavity roll and in back of the hopper, another is located under and behind the cavity roll, and the third is located under and in front of the cavity roll.
  • a distribution roll is located under such third idler roll, and directly above the moving sheet.
  • a deflector gate associated with such distribution roll, provides a distribution gate for the granules which fall onto the sheet in a uniform layer thereon. A number of such units are used in tandem to vary the pattern of granules applied to the moving sheet as desired.
  • FIG. 1 is a fragmentary view mainly inside elevation of a granule applicator unit illustrative of the invention.
  • FIG. 2-6 are similar views illustrative of the operation of such unit.
  • the illustrated unit 10 is located over the longitudinal path of the sheet 12 which moves continuously in the direction of arrow 14.
  • the unit 10 comprises a granule hopper 16, a cavity roll 18, a belt 20, three idler rolls 22, 24 and 26, a distribution roll 28, and a deflector gate 30.
  • the roll 18 is provided with a cavity 32 in the periphery thereof; and the lower portion of the hopper with a resilient seal 34 surrounding the outlet 38 in the bottom thereof.
  • Rolls 22, 24 and 26 are located above, behind and under the roll 18 so that the belt 20 contacts a part of the circumference of the roll 18 behind and under the same.
  • the roll 26 is located directly above roll 28, and the gate 30 is spaced from the roll 28 to provide a distribution roll feed opening 40 above the sheet 12.
  • the cavity roll 18 is driven in unison with the distribution roll 28 and sheet 12 by a common drive motor (not shown) and in turn drives belt 20.
  • an example of the sequence of operation of unit 10 is as follows:
  • the pocket volume is fixed, the quantity of granules applied is the same for every drop. Also, since the cavity roll and distribution roll are tied directly to and driven in proportion to the machine speed, the rate with respect to the sheet speed at which granules are dropped from the distribution roll is constant at all speeds and therefore granule distribution is always uniform.
  • this invention was developed primarily for the application of roofing granules to the roofing sheet, it could be employed in other applications where it is desired to apply a known quantity of granular or powdery material to a moving sheet or other surface in a predetermined sequence and predetermined thickness of material.
  • the width of application (at right angles to the direction of sheet travel) of the material on the sheet can be varied by changing the width of the cavity (inthe direction parallel to the axis of the cavity roll).
  • the volume of the cavity can be changed by changing one or more of the dimensions of the cavity.
  • the depth of the material as applied to the sheet or surface can be changed by changing the volume of the cavity and/or the size of the opening between the distribution roll and deflector gate and/or by changing the speed of the distribution roll with respect to the sheet or surface speed.
  • timing or sequencing and spacing of applications of the granular material on the sheet can be changed by simply adjusting the drive ratio between the applicator unit and the sheet.
  • An improved granular applicator apparatus for applying a fixed quantity of granular material to a continuously moving sheet, including:
  • a hopper for storing granular material
  • a cavity roll provided with a single cavity in the periphery of said roll adapted to receive granular material from said hopper;
  • a belt adapted to co-act with said roll to prevent the release of granules from said cavity until a designated time
  • a distribution roll disposed beneath said belt, moving in concert with said cavity roll and driven in proportion to said moving sheet, to thereby enable the uniform distribution of granules;
  • an idler roll disposed directly above said distribution roll cooperating with a gate means spaced from said distribution roll forming a granule feed opening above said sheet for the distribution of granules onto such sheet.
