Definitions

  • This invention relates to apparatus for handling continuous paper strip material of the type that folds upon itself by means of multiple folds, successive ones of which face in opposite directions.
  • One such material is sold by Moore Business Forms, Inc., under the name Fanfold continuous forms.
  • a continuous microfilmer is a photographic recording apparatus in which the document being photographed and the photographic recording media are moved simultaneously and in synchronism across the photographic exposure.
  • the continuous strip material handling apparatus of the present invention comprises a novel receiver for receiving the zigzag-folded forms that I refer to as strip material having a plurality of successive reverse folds, as shown in the drawings appended hereto, and novel means for directing the material into the receiver.
  • the apparatus also comprises mechanism whereby a predetermined spacial relation is maintaincd between the uppermost material in the receiver and the throat through which the material is discharged, regardless of the amount of material received in the hopper.
  • One object of the present invention is, therefore, to provide an improved handling apparatus for folded continuous strip material.
  • Another object of the present invention is to provide a receiver for receiving such material, which maintains substantially a constant concave configuration of the up permost material in the receiver with respect to the discharge throat.
  • Yet another object of the present invention is to provide folded strip material handling apparatus in which the receiver is moved relative to a discharge throat through which the material passes in its movement to the receiver, so as to maintain the predetermined spacial relation referred to above.
  • Another object of the present invention is to provide in combination with a document copying apparatus an improved apparatus for receiving the folded strip material as they are discharged from the copying apparatus after photographing.
  • Another object of the present invention is to provide in combination with a document copying apparatus a receiver which is movable to maintain the predetermined spacial relation mentioned above.
  • FIG. 1 and FIG. 2 are somewhat at schematic end elevational views showing the strip material handling apparatus in accordance with the present invention as it is utilized in combination with a document copying apparatus;
  • FIGS. 3, 4-and 5 are enlarged detail views showing the discharge throat and receiver with the material directing guides in various positions;
  • FIG. 6 is a detail perspective view of the concave receiver members and base or carrier therefor.
  • FIG. 7 is a front elevational view showing the receiver in position and operatively associated with means for moving the hopper relative to the discharge throat of the apparatus.
  • the numeral 11 designates a document copying apparatus and more specifically a continuous microfilmer of a type which is well known in the art.
  • the Recordak Commercial Microfilmer Model RE-l
  • the copying apparatus 11 has a drum 13 which is driven by a motor not shown so that the document being copied is advanced through a. photographing station where it is illuminated and the image of the illuminated document is recorded on film in another part of the apparatus.
  • Such film moves in synchronism with the movement of the document through the photographing station and in a direction opposite the document movement.
  • the numeral 15 designates a supply hopper in which a stack of folded strip material F is positioned prior to the feeding of the material through the copying apparatus for photographing. As is apparent from the drawing, the material F is led over a guide 17 and into the copying apparatus 11 where the leading edge of the material is engaged by the drum 13 and advanced through the copying apparatus.
  • the numeral 19 designates a belt which is driven from the motor (not shown) Within the copying apparatus 11 and which in turn drives the discharge rollers 21 and 23 so that the material F is discharged into a receiver in the manner which will behereinafter set forth.
  • a pair of guides 29 and 31 are pivotally mounted on brackets 33 and 35 (FIG. 5) formed on guide plates 25 and 27, respectively for pivotal movement about fixed axes.
  • the guides 29 and 3-1 are formed preferably of a light Weight spring wire or rod material which has a curved configuration and is rounded at the outer end of the guides so as to present a smooth surface to the material F.
  • the respective guides include counterweights 37 and 39. The counterweights as a result of gravity hold the guides in their respective upper positions in contact with stop members 41 and 43, respectively, or on the opposite side of their respective pivot axes when moved to such position. Such upper positions for the guides are shown in FIGS. 1, 2, and 5 of the draw- 3 ings, while guide 31 is shown in the other position in FIGS. 3 and 4.
  • the receiver which is generally designated by the numeral 51, comprises a base plate or carrier 53 and a plurality of resilient flexible concave members 55, 55, 55", etc., which are afiixed to the plate 53 by means of screws or rivets 57, see FIGS. 3 to 5.
  • Plate 53 rests on a movable support 59 which is a triangularly shaped plate having bushings 61, 63, and 65 mounted in its three corners. The bushings are threaded for engagement with the power screws 67, 69, and 71, respectively.
  • Screw 69 is driven by an auxiliary motor M through a gear reducer '73, drive chain 75 and a sprocket 77 mounted on the screw.
  • Screw 69 like screws 67 and 71 is vertically supported for rotary movement by a base member 79 and each of the screws has a sprocket attached to the lower end thereof and engaged by a chain 81 so that each of the screws is driven simultaneously and in synchronism and at the same speed.
  • the screws are also suitably journaled at their upper portions as at 79'.
  • counter-balanced springs (not shown) instead of motor M, may be used in cooperation with the weight of material F to control vertical positioning of the carrier 53.
  • Guides 29 and 31 can be selectively positioned in either of two positions.
  • guide 31 can be positioned in the extreme positions of FIGS. 3 and 5, respectively, and guide 29 has two similar extreme positions.
  • each guide member is defined by its contact with the adjacent stop member 41 or 43.
  • the counterweights 37 and 39 hold the guides to which they are attached, in these extreme positions.
  • the guides In the guide positions of FIG. 3 the guides have been manually positioned to direct the leading edge of the folded material transversely toward stop 41. This direction has been selected because the first fold in material F faces as shown in the drawings. If the first fold faced in the opposite direction, the guides would be manually positioned to guide the leading edge of material F transversely toward stop 43. In such positions, guide 31 is positioned in contact with stop 43 and guide 29 will lie in a position corresponding to that of guide 31 in FIG. 3.
  • the leading edge of the material will be directed by the guide 31 to contact stop 41 and the weight and movement of the material will begin to pivot guide 31 about its axis as illustrated in FIG. 4.
  • guide 31 is moved by the material until guide 31 eventually goes beyond its center position so that the counterweight causes it to flip to its uppermost position in contact with stop 43 as illustrated in FIG. 5.
  • the first fold in the fanfold forms is disposed in contact with and in a curved configuration on resilient members 55 and because of the fold the material starts back on itself in contact with the first layer of material in the receiver.
  • the members 55, 55, 55", etc. are made of a resilient material preferably a light weight spring steel and are sufficiently flexible that the weight of the material F piling up on them tends to flatten them, that is, to increase the radius of curvature of the members 55, etc.
  • the members 55, 55', 55", etc. have a much greater radius of curvature than they do in FIG. 1 because of the weight of material F. It has been found that the stack of fold lines along each lateral edge of the folded material is thicker when loosely fed into a receptacle, tending to cause continual reduction in the radius of curvature of the upper layer of material as the stack increases in height. Such change is likely to interfere with orderly folding and stacking.
  • the curve of tion of guide 31 in FIG. 3 is moved out of the way by the moving material form and the guides are not utilized during the rest of the feeding of that particular continuous strip of folded material.
  • the apparatus of the present invention facilitates the rapid handling of folded forms permitting the same to be uniformly stacked and conveniently retrieved for use in further associated equipment.
  • pivotally mounted means being manually movable to direct said leading edge of said strip material selectively to either side of the said path of movement.
  • said receiver comprises resilient flexible concave means presenting a concave surface for receiving said material, the flexibility of said means being such that the material received on said surface progressively flattens said means as the weight of the folded material thereon increases.
  • Apparatus according to claim 1 in combination with and receiving said material from a microfilming machine.
  • a device for linearly discharging continuous strip material having a plurality of successive reverse lines of fold through a discharge throat at a predetermined linear speed, and a strip material receiver positioned below said discharge throat and centrally aligned therewith comprising resilient flexible concave means spaced from an axis and presenting a concave surface facing said throat and having a predetermined radius of curvature with respect to said axis for first receiving said continuous strip material in folded, stacked condition thereon, and means for moving downwardly said receiver, relative to said throat, while maintaining its central alignment with said throat, simultaneously with the discharge of said continuous strip material from said throat and at a speed proportional to the rate of discharge to maintain a predetermined spatial relation between said throat and the uppermost portion of the strip material in said receiver, the flexibility of said concave means being such that the increasing weight of the strip material received on said means progressively flattens said means thereby increasing the radius of curvature thereof so as to compensate for the tendency of said uppermost portion of received strip material to take a radius of curvature which is less
  • said concave means comprises a plurality of spaced spring members, and a carrier therefor to which said members are attached.
