Definitions

  • ABSTRACT An interceptor for opening up gaps at measured intervals in a continuous stream of shingled papers carried by a belt conveyor, comprising a paper lift disposed below said papers, one end of which tilts up to raise the papers off the belt, while a spring-loaded plunger simultaneously moves downwardly from above to pinch the papers against the lift, allowing the last paper ahead of the gap to pull out, while the papers behind it are stopped.
  • a generally horizontal, elongated paper leveler moves downwardly from above and cooperates with the paper lift to form a long wedge-shaped space into which the papers crowd in a shortened shingle as the conveyor continues to advance.
  • the lift lowers the papers back onto the conveyor belts, and the leveler and spring-loaded plunger are simultaneously raised, releasing the stream of papers to move with the conveyor.
  • the present invention pertains generally to conveyors for carrying continuous streams of shingled papers, such as are delivered by a sheet, or web-fed perfecting press. More specifically, the invention has to do with an interceptor mechanism for opening up gaps at predetermined intervals in the stream of shingled papers going to a counting and stacking machine of the type shown in U.S. Pat. No. 3,543,651. These gaps actuate the stack-forming mechanism in the said machine, and it is therefore essential that the gap-forming mechanism operate in a precise and accurate manner, so that the number of papers going into each stack will be the exact number wanted neither more nor less.
  • the primary object of the present invention is to provide a new and improved interceptor mechanism for engaging and holding back the papers on a conveyor, thereby opening up gaps in the otherwise unbroken stream of shingled papers.
  • the advantageous features of the invention is that it is accurate and precise in operation, and preserves the shingle of the stream of papers while opening up the gaps.
  • Another object of the invention is to provide an interceptor that is extremely versatile, and capable of accommodating itself to all sizes, shapes and thicknesses of papers, so that it can handle virtually anything that it is called upon to handle.
  • various adjustment are provided that allow the interceptor to be adjusted to fit any width or thickness of papers.
  • FIG. 1 is a fragmentary, top plan view of a belt conveyor for transporting papers, showing an interceptor embodying the principles of the invention
  • FIG. 2 is a side elevation of the same, showing a stream of shingled papers traveling on the conveyor;
  • FIG. 3 is a view similar to FIG. 2, showing the interceptor in action, with the stream of papers stopped at the point of engagement by the apparatus;
  • FIG. 4 shows the apparatus at the instant of releasing the papers, allowing the bunched-up accumulation of papers to resume movement along the conveyor belt, with a gap opened up in the line.
  • the interceptor apparatus of the invention is designated in its entirety by the reference numeral l0, and is integrally associated with a conveyor system comprising a pair of belt conveyors 12 and 14, connected together, end-to-end.
  • Each of the conveyors l2, 14 includes an elongated supporting framework made up of two laterally.-spaced, parallel side bars 16, which are connected by a top plate 18.
  • Transverse shafts 20 and 22 are joumaled at the ends of the conveyor frame in bearings 24, and mounted on the shafts are pulley wheels 26, around which laterally spaced belts 28 are trained.
  • Shaft 20 of conveyor 14 is driven from conveyor shaft 22 by a sprocket and chain drive 23.
  • the conveyor system consisting of conveyors 12 and 14, is known as an accepting conveyor, as it receives a continuous stream of shingled papers 30 from a sheet or web-fed perfecting press, or other paper handling machine, such as a collator, folder, stuffer, or the like that delivers a continuous stream of shingled papers or other artiles, and transports these papers to a counting and stacking machine of the type shown and described in our US. Pat. No. 3,327,597. Papers 30 move along the conveyor on belts 28 from right to left, as viewed in the drawings, and conveyor 12 discharges the stream of papers onto conveyor 14. For the purpose of actuating the counting and stacking machine of our patent, it is necessary that gaps be opened up in the stream of papers at predetermined intervals, and this is accomplished by the interceptor apparatus 10.
  • Parallel arms 46 are located in vertical planes in the spaces between adjacent pairs of conveyor belts 28, and the outer ends of each pair of parallel arms are pivotally connected to a head 48.
  • the outer two heads 48 each have a plunger 50 slidable vertically with respect to the arm; said plunger being springloaded downwardly by a helical coil compression spring 52.
  • the spring-loaded plunger 50, 52 is removably mounted on the head 48 as a unit, so that two plungers can be used in any two of the three heads 48, depending upon the size or width of the papers, or other physical characteristics of the stream of papers on the conveyor.
  • each of the paper levelers 58 comprises an elongated, flat, substantially horizontal member with an upwardly curved end 60, so that the leveler resembles a ski.
  • the member 58 extends parallel to the line of travel of papers carried by belts 28, and passes under shaft 42, to which it is connected by an arm 62.
  • Arm 62 is also adjustable in length and, like arm 54, extends downwardly and to the left, at an angle, from shaft 42.
  • a rock shaft 64 Extending transversely across the width of conveyor 12 below top plate 18 is a rock shaft 64, the ends of which are rotatably supported by bearings mounted on the side bars 18.
  • Link 68 passes upwardly through a hole 72 in the top plate 18, as shown in FIG. 1.
  • counterclockwise rotation of shaft 64 causes arm 70 to be pulled downwardly by the link 68, which rotates chaft 38 in the counterclockwise direction, swinging the arms 44 and 54 down to the vertical position shown in FIG. 3. This lowers the paper leveler 58, and also causes the plunger 50 to move downwardly, so that the bottom end thereof contacts the papers.
  • each lifter comprises an elongated, flat strip of metal, the right-hand end of which (as viewed in FIG. 1) is bent downwardly and hooked through an aperture 82 in top plate 18.
  • Paper lifter 80 and paper leveler 58 cooperate to form a long, tapered, wedge-shaped space, into which the shingled stream of papers continues to crowd as the conveyor continues to advance.
  • the paper leveler keeps the papers from over-running one another, and preserves the shingle, although the length of the shingle is considerably shortened during the operation of the interceptor.
  • the total time required to open up the gap is only about a second, or less, and upon completion of the gap-forming process, the interceptor releases the papers and allows them to continue moving along on the conveyor.
  • the gap is shown at 84, and while this gap may be as much as five to eight inches in distance at the time it is formed, the gap is usually closed up considerably in transferring the papers from faster running conveyors to slower running conveyors, either on the conveyor system leading to the counter-stacker machine, or on the machine, itself.
  • the interceptor apparatus 10 is actuated by an air cylinder 84 located on the underside of the conveyor frame, adjacent one of the side bars 16.
  • the base of the cylinder 84 is mounted on a shaft 85 extending transversely across the conveyor frame from one side bar to the other, and the piston rod 86 of the cylinder is connected to an arm 88 projecting downwardly from rock shaft 64.
  • the ends of the cylinder are connected by air lines to an electrically operated valve 90, and the latter is connected by a line 92 to a source of air pressure.
  • the valve 90 is actuated by an electrical impulse from an electronic counting circuit on the counting and stacking machine, which determines the spacing between gaps 83.
  • an interceptor for opening up gaps at predetermined intervals in said stream of papers, comprising:
  • a paper lift disposed beneath the stream of papers, and operable when actuated to lift the papers clear of the conveyor;
  • a vertically movable plunger disposed above said stream of papers, said plunger being operable to move downwardly to engage said papers when they are raised by said lift, said papers being pinched between said plunger and said lift, thereby stopping the papers thus contacted from being dragged along by friction of the underlying papers ahead;
  • said plunger being carried by a head mounted on a pair of vertically swingable, parallel arms arranged one above the other, said plunger being held perpendicular to the top surface of said papers, and being slidable vertically with respect to said head;
  • spring-loading means extending said plunger downwardly, said spring-loading means being compressible when said plunger engages said papers, thereby exerting a yielding spring pressure on the papers.
  • an interceptor for opening up gaps at predetermined intervals in said stream of papers, comprising:
  • said lift comprising a first elongated member extending parallel to the line of travel of said papers, the downstream end of said member being movable vertically so that it can be elevated to lift the papers clear of the conveyor; vertically movable plunger disposed above said stream of papers and mounted on a pair of vertically swingable, parallel arms arranged one above the other, one of said arms being fixed to a transverse shaft extending across the conveyor above the papers, said plunger being operable to move downwardly to engage said papers when they are raised by said lift, said papers being pinched between said plunger and said lift, thereby stopping the papers thus contacted from being dragged along by friction of the underlying papers ahead; a paper leveler comprising a second elongated member disposed above said stream of papers and extending parallel to the line of travel thereof, said second elongated member being swingably supported on a pair of parallel arms so that it can swing downwardly toward said first elongated member at the same time that the latter is elevated, said first and second elongated members cooperating to form
  • one of said parallel arms supporting said paper leveler being also fixed to said transverse shaft; and means for rocking said shaft at the same time said lifter is elevated, thereby lowering both said plunger and said paper leveler simultaneously.
  • rock shaft having a first arm attached thereto which is connected by a link to said downstream end of said paper lift, and a second arm attached to said rock shaft which is connected by link means to said transverse shaft above said papers, whereby rocking movement of said rock shaft causes said paper lift to be raised and said plunger and paper leveler to be lowered simultaneously; and means for rocking said shaft.
