Definitions

  • ABSTRACT A delivery arrangement including a conveyor and take-off mechanism for delivering a series of printed sheets onto a pile, in which nozzles are provided distributed along the width of a sheet for directing a jet of air in a direction opposite to sheet movement.
  • a guide plate spaced under the sheet and extending upstream from the region of the nozzles serves to confine the jet.
  • lnterposed between the guide plate and the sheet path are a series of longitudinally extending friction or land members toward which the sheet is drawn during the course of transport, the jet and friction members serving, together, to decelerate the sheet as it is removed by the take-off mechanism.
  • the guide plate is longitudinally slit at intervals to form windows defining extensive struck-out portions and intervening frames, the struck-out portions, bent downwardly from the frames, being utilized to confine the jet while the intervening frames provide the frictional engagement.
  • the nozzles are fed by a manifold which is divided into zones which are fed by separate controllable valves in accordance with the width of the sheets being handled. Such nozzle and guide plate assemblies are preferably used in successive sections of the sheet conveyor for control of the sheet during change of direction and to eliminate flutter.
  • an object of the invention to provide a sheet decelerating arrangement vwhich is simple, inexpensive and compact and which may be employed universally for keeping sheets under control in a conveyor or delivery system.
  • FIG. 1 is a diagrammatic side elevational view of a delivery arrangement employing the present invention.
  • FIG. 2 is a perspective view, in partial section, showing the nozzle and guide plate assembly of FIG. 1 in somewhat enlarged form.
  • FIG. 3 is an end view of the nozzle and guide plate assembly showing the path of sheet travel and the direction of air flow.
  • sheets 13 The chain is trained around rollers or I sprockets l4, 15 which are driven at press speed via a connection 16 from the press drive 17. Sheets 13 may be printed on either one or both sides in a suitable lithographic printing press (not shown). 1
  • the purpose of the conveyor is to convey sheets along a path 19 to a-position above a delivery pile 20 where the sheets are supported on a platform 21 which is suspended upon chains diagrammatically indicated at 22 forprogressive sinking movement as sheets are added to the top of the pile.
  • a series of front guide members 23 are provided at the left-hand side of the pile and a series of rear guide members 24 are provided along the right-hand side of the pile.
  • the means for maintaining the top of the pile at a constant'leve l by gradual lowering of the platform 21 does not form a part of the present invention and for details of the automatic level adjusting pile 20, a take-off mechanism 30 is provided.
  • the take off mechanism does not per se form a part of the present invention, and any suitable take-off mechanism, synchronized with the arrival of the sheets, may be used, for example, that illustratedin German Pat. No. 613,007.
  • the take-off mechanism 30 shown diagrammatically in FIG. 1 it includes grippers 31 mounted upon a reciprocated member 32 which is reciprocated by an arm 33 pivoted at 34.
  • a cam 35 is provided mounted upon the shaft of the member 15 and having a cam follower 36 in the form of a roller secured to the arm.
  • the cam follower is maintained in contact with the cam by means of a tension spring 37.
  • Means are provided for releasing the grippers 12 on the conveyor chain so that the leading edge of the sheet may be gripped by the grippers 32 which rapidly decelerate the-sheet so that the leading edge is reduced to zero velocity by the time the leading edge arrives at the front pile guides 23, at which time the grippers 31 are released to allow the sheet to settle onto the top of the pile.
  • an air manifold 40 is provided extending the maximum width of 5 the sheets and which is of rectangular cross section having a top surface 41, bottom surface 42, an upstream side 43 and a downstream side 44.
  • the downstream side is suitably secured to a frame member indicated generally at 45.
  • a nozzle plate 50 is provided which is spaced a short distance above the topsurface 41 -of the manifold to define a limited headspace 52 so that air is ejected, in the form of a jet, through the elongated nozzle opening 53.
  • the manifold is formed with a longitudinal opening, or series of openings, 54.
  • the nozzle opening 53 may be continuous or the opening 53, and headspace 52, may be occupied by a series of spacers to define a series of closely spaced nozzle openings which cooperate with one another to produce a jet along the width of the sheet.
  • the term nozzle means has been used in the claims to cover both of these possibilities.
  • the entire manifold 40 may be pressurized, we preferably provide means for dividing up the manifold into a series of zoned compartments. Zoning may be accomplished by spaced baffles 55, only one of which is shown, with adjacent compartments being fed by separate conduits 56, (only two of which are shown) via separate air valves 57 which are connected to a source of pressurized air 58. By opening only a portion of the valves 56 the flow of air may be tailored to the width of the sheets being handled. However, it will be understood that the width of the jet need not be precisely tailored to the width of the sheets and the term extending along the width of a sheet used in the claims refers primarily to direction rather than extent.
  • the guide plate 60 has a downwardly extending mounting flange or base portion 61 which. is secured to the upstream wall 43 of the manifold and an upstream extending portion 62 which is bent downwardly into curved or horn" shape to define a flaring space indicated at 63 under the sheet 13 and through which the jet of air, indicated at J, passes.
  • the pressure in the space 63 becomes just slightly less than atmospheric, which tends to draw the passing sheet 13 (see FIG. 3) downwardly in the direction of the guide plate 62.
  • the discharge of air, under pressure, below the sheet does not blow" the sheet upwardly from its normal path of delivery, as might be expected, but it acts, instead, to suck the sheet downwardly into intimate contact with the jet which is travelling in the opposite direction. As a result the sheet is held down so that the air of the jet impinges on the underside of the sheet, tending to hold it back in its course of movement.
  • a friction means is interposed between the guide plate and the travelling sheets so that, as the sheets are sucked downwardly by the jet action, the sheets are drawn into light frictional engagement which augments the direct effect of the air jet in braking the forward speed of the sheets.
  • the friction means is preferably in the form of relatively narrow and relatively upraised lands or tongues which extend longitudinally of the path of travel of the sheets and which are bent downwardly at a shallow angle so as to form a smoothly curved frictional surface, at least a portion of which may be engaged by the underside of the sheets.
  • the guide plate 62 is formed, by a slitting operation, with a series of windows which are slit along three sides as indicated at 71, 72, 73.
  • the slits 71-73 moreover define window frames in the form of the narrow relatively upraised tongues 75 which are distributed in the width dimension of the sheet and which are interconnected, at the ends, by an apron 76.
  • the apron 76 may be slotted as indicated at 77 for the securing, if desired, of sheet guide belts or the like.
  • the degree of braking effect may be varied from a low setting, where the impingement of air alone on the underside of a sheet serves to decelerate it, to a higher velocity in which the sheet is drawn into contact with the tongues 75, the degree of engagement depending upon the velocity and upon the length and degree of curvature of the tongues 75 as well as the struck-out portions 62a which guide the air.
  • the impingement of the air jet upon the underside of the sheet has a steadying as well as decelerating effect upon the sheet. Control of the sheet is still further improved, and any tendency toward whipping or fluttering is eliminated, by the action of the lands or tongues 75, with the result that the sheets are fully under control at all times.
  • synchronized means (not shown) are provided for releasing the grippers 12 on the conveyor chain and for engaging grippers 31 of the take-off mechanism which grip the leading edge of the sheet and which decelerate it to a standstill at the forward pile guides 23.
  • the air jet provides a frictional drag on the underside of the sheet which is enhanced by the frictional effect of the tongues 75, with the degree of the latter, depending, as stated, upon the jet velocity.
  • the decelerating means operates over a broad area of the sheet, the entire sheet is decelerated without any tendency for the body, or trailing edge, of the sheet to tend to overtake the leading edge, so that the sheet remains flat and free of wrinkling, waving or doubling-over as it settles into place on the top of the pile.
  • the structure described above inherently prevents any possibility of intimate contact between the sheet and the nozzle plate 50.
  • the reason for this is that the air which emanates from the nozzle 53 induces a flow of a film of air through an inlet opening 80 at the downstream side of the nozzle plate. This film of air serves to limit the degree of contact between the sheet and the nozzle plate.
  • nozzle-guide plate assemblies may be provided in multiple along the sheet path.
  • a second nozzle and guide plate assembly B constructed exactly as shown in FIGS. 2 and 3, may be provided along the ascending section of the conveyor for the purpose of holding the sheet in a taut and controlled condition as it changes direction into thefinal leg of its journey free of any tendency toward whipping or fluttering.
  • nozzle-guide plate assembly B or any other similar unit employed along the sheet path for braking purposes
  • the term adjacent the pile is a relative term not requiring immediate adjacency.
  • the assembly may be oriented vertically as well as horizontally (A and B, FIG. 1) the terms above and below, or under, are relative terms; indeed the unit may be operated inverted, if desired, without departing from the invention.
  • the assembly is compact, may be mounted at the delivery pile or wherever it is desired along the sheet path and is inherently economical in construction and trouble free in operation.
