Definitions

  • the disclosed brake is actuated by a single electrical solenoid, and provides a positive paper stop at two spaced points on the paper substantially simultaneously and evenly, thereby preventing paper path skew.
  • Two individual linear brake rods are pivotally connected to opposite ends of a teeter arm transverse the paper path.
  • the solenoid is pivotally connected to the center to the teeter arm.
  • the two brake rods are commonly driven but pivotable with respect to one another to automatically prevent one from applying any pressure to the paper until the other has also made contact, and then to automatically provide even and self adjusting brake pressure.
  • Each has an independent return spring and is normally maintained slightly away from the web.
  • This brake is disclosed operating in combination with feed means and a fixed curved perforated paper bubble forming member for smooth registered feeding into electrostatographic imaging means.
  • the present invention relates to electrostatographic web feeding apparatus providing accurate sheetfeeding with web stopping and cutting, including an improved web cutter brake which operates very rapidly and evenly and prevents web skewing.
  • FIG. 1 is a side view of an exemplary web feeding apparatus embodiment of the present invention, partially schematicised for clarity;
  • FIG. 2 is basically the same as FIG. 1, but showing the web brake and cutter actuated;
  • FIG. 3 is a top view of the embodiment of FIGS. 1 and 2, illustrating the perforated web bubble forming platen;
  • FIG. 4 is a front view, transversely across the web path, of the embodiment of FIGS. 1-3, illustrating details of the web brake structure.
  • This apparatus 10 includes a paper brake 12 operating in conjunction with a paper cutter 14 for cutting a web of paper 16 from a paper roll 18 into individual image receiving sheets.
  • the apparatus 10 also provides accurate sheet feeding of the paper 16 into an imaging means 20 in registration with an image thereon.
  • the imaging means 20 shown here schematically is a portion of a conventional.xerographic drum and associated transfer corotron for the transfer of a xerographic toner image to the paper 16 in a conventional manner.
  • many of the components of the apparatus 10 and the associated electrostatographic system are conventional, and, therefore, need not be described herein. Those components which are conventional are illustrated schematically for clarity.
  • first web feed means 22 here comprising a continuously rotating conventional set of paper feeding friction drive wheels.
  • This first feed means 22 is shown here' directlyadjacent the upstream end of a hump member 24 which extends into and deforms the path of the uncut web to form a web or hump.
  • the web feeds through the paper brake 12 located at the downstream end of a hump member 24.
  • the web then passes through the closely adjacent (immediately downstream) conventional paper cutter 14, which is adapted to rapidly sever the entire web transverse the web direction of travel so as to cut the web into desired lengths of individual sheets of paper.
  • the cutter 14 is followed downstream by a second conventional paper feeding means 26 for further feeding the paper on into the imaging means 20.
  • the second web feed means 26 may comprise continuously operating conventional feed rollers operating at substantially the same web feeding speed as the first feed means 22, e.g., approximately 10 percent faster.
  • FIG. 2 illustrates both the paper cutter 14 and paper brake 12 being actuated to'stop and then evenly cut the web 16. It will be appreciated that the operation of these two members is coordinated and synchronized with the position of the image on the imaging means 20, as described in the cited references. During this stop and cut operation the web is completely stopped by the paper brake 12, as will be discussed further herein, so that the web will not be moving as the paper cutter 14 is operating. This insures a smooth and even cut and prevents jamming or skewing of the web during the paper cutting operation.
  • the imaging means 20 is upstream.
  • This bubble is caused to expand smoothly in a direction normal the web path while the downstream edge of the web is stopped by the paper brake 12, so as to absorb and confine the additional length of paper being continuously fed downstream towards the paper brake 12 by the first feed means 22 during paper braking.
  • the disclosed hump member 24 prevents this by providing positive pre-forming of the bubble and control over both the position and direction of the web bubble during both its expansion and contraction, for significantly improved reliability. It may be seen that the hump member 24 provides a continuous bubble or loop in the otherwise substantially planar path of the web 16 at all times, including the time periods in which the paper brake 12 is not engaging the web at all. Thus, when the paper brake 12 is actuated, the paper bubble is already pre-formed, i.e., initially partially buckled in the desired position and direction of buckling or bubbling.
  • the hump member 24 is a substantially continuous and smooth surfaced fixed platen extending shown, of much less than 90. Thus, it does not present any significant obstruction or significant frictional resistance to the feeding of the web over its surface.
  • hump member 24 is multiply apertured to prevent a vacuum from forming between it and the web 16. This allows the web 16 to very rapidly rise away from the hump member 24 into an expanded web bubble when the paper brake 12 is actuated. The rapid expansion of the web bubble requires the large area of the web over the hump member 24 to rapidly move away from its normal directly overlying position. By making the hump member as a thin, slightly curved, metal plate which is highly multiply perforated (to offer an insubstantial air flow resistance) this can be achieved. The hump member 24 does not offer any significant resistance to the rapid increase or expansion of the web bubble away from its supporting surface. Yet the web 16 is initially fully and continuously supported by the surface of the hump member 24.
  • means are preferably provided to limit its longitudinal extent at the upstream and downstream ends of the hump member 24. In the apparatus this is provided at the upstream end of the feed means 22 and at the downstream end by a curved paper guide or deflector 28 directly adjacent the entrance to the paper brake 12.
  • blower or fan means may be additionally provided for blowing a positive air pressure flow from underneath up through the perforated hump member 24 against the bottom of the web 16. This provides further insurance of the smooth, rapid, outward expansion of the web bubble away from the surface of the hump member 24 during paper braking.
  • the web brake 12 provides, upon actuation, a very rapid stopping of the web without skewing, tearing or buckling of the web. These have been problems with many prior paper brakes when used for rapidly stopping for cutting a segment of a rapidly moving web.
  • the paper brake l2 automatically provides substantially simultaneous and even pressure stopping engagement with the web at two points spaced apart transversely on the web, thereby positively preventing web skewing from either the braking itself or from the operation of the paper cutter 14.
  • the paper brake 12 is actuated in conjunction with the paper cutter 14, but its braking operation should be completed prior to the beginning of the cutting operation of the paper cutter 14. That is, the web is preferably fully stopped in the paper cutter 14 before the paper cutter begins to cut the paper. Also, the paper brake 12 is preferably closely adjacent the paper cutter. It is desirable that the web brake 12 engage the web only intermittently and as briefly as possible only during the operation of the paper cutter 14, so as to interfere as little as possible with the normal web feeding, and to require as small as possible a web bubble expansion over the hump member 24. The brake 12 is particularly suited for such rapid braking and release of the web.
  • the paper brake 12 is preferably driven by a single short stroke linearly operating commercially available electrical solenoid 30.
  • the solenoid 30 is shown mounted to a fixed frame 32 with its operating rod or plunger stroke normal the plane of the web 16.
  • the operating plunger of the solenoid 30 is pivotally connected to the center of a teeter arm 34, so that actuation of the solenoid 30 draws the teeter arm 34 upwardly towards the frame 32 and the web 16.
  • the teeter arm 34 is free to rotate or teeter intermediately relative to the solenoid 30 about the pivotal interconnection provided by pivotal connecting means 36, which may be a conventional pin connection.
  • the teeter arm 34 is an elongated bar extending transversely across a major portion of the web, and generally parallel thereto. It is preferably a thin plate set edgewise (perpendicular) to the web so as to form a strong, but light weight beam for transmitting the force of the solenoid 30 to its outer ends. It may be seen that these outer ends of the teeter arm 34 are each connected to the bottom ends of elongated vertically extending brake rods 38 and 40 respectively. These connections are also conventional pivotal pin connections. Both of the brake rods 38 and 40 are preferably thin cylindrical steel rods extending upwardly from the ends of the teeter arm 34 perpendicularly toward the web 16. They are preferably restrained or guided for purely linear reciprocal movement in this direction by a pair of fixed cylindrical slide guides 42, shown in the partially broken away section around the brake rod 40.
  • the brake rods 38 and 40 each have frictional brake pads 44 and 46, respectively, at their upper ends adapted to engage the bottom of the web 16 ,and also to force the web 16 upwardly against directly overlying fixed brake pads 48 and 50.
  • frictional brake pads 44 and 46 respectively, at their upper ends adapted to engage the bottom of the web 16 ,and also to force the web 16 upwardly against directly overlying fixed brake pads 48 and 50.
  • connection taneously driven by the connection to the teeter arm 34 by the solenoid 30 toward the web when the solenoid is actuated.
  • the two brake rods are individually freely pivotable with respect to one another.
  • the teeter arm rapidly pivots to bring the other brake pad into engagement with the paper.
  • the paper brake 12 cannot stop the paper at one braking point prior to its being stopped at the other braking point.
  • the described pivotal mounting also insures that the braking force remains even between the two braking areas at all times, during both actuation and removal of the braking forces.
  • the solenoid 30 cannot apply an uneven force between the two brake rods.
  • the two separate braking actions provided by the two brake rods are also automatically selfadjusting regardless of the initial spacing or adjustment of the brake pads relative to the web.
  • the described pivotal connections prevent any tortional or lateral forces from acting on the brake rods. Therefore, they can be reciprocally slidably mounted in the simple cylindrical bushings provided by the rod guides 42 without any danger of binding during operation.
  • each brake rod equidistantly on opposite sides of the pivotal connecting means 36 allows pivotal movement of the teeter arm relative to the web in direct response to uneven pressures between the brake pads 44 and 46.
  • the teeter arm 34 cross-transmits and evenly balances these pressures while at the same time rapidly applying braking pressure to both brake pads through the common central upward movement of the same pivotal connecting means 36 by the solenoid 30.
  • Each brake rod 38 and 40 has a separate return spring 52 and 54, respectively, to normally urge and re tain it away from the web 16 except when the solenoid 30 is actuated (energized). These are preferably sufficiently strong coil springs under pre-compression to rapidly inactivate the paper brake as soon as the electrical energization is removed from the solenoid 30.
  • Mechanical spacing stops 56 and 58 which are independently screw adjustable, are provided as brake adjustments to limit the maximum extent of movement of the ends of the teeter arm 34 away from the web 16. This thereby determines the maximum spacing of the brake pads 44 and 46 out of contact with the web. By adjusting the stops 56 and 58, the brake rods 38 and 40 can be independently maintained only a short distance from the web. This means that only a very short stroke of the solenoid 30 is required to bring the brake pads into paper contact, for faster braking action upon actuation of the solenoid 30.
