Definitions

  • This invention relates to apparatus for feeding a series of sheets of paper from a storage compartment and more particularly to such apparatus especially adapted for use with photocopy machines.
  • the present invention provides a mechanism for dividing the paper storage compartment to provide a plurality of levels, each level supporting a stack of copy paper of a particular size.
  • the mechanism includes apparatus for feeding the topmost sheet in one of the stacks and means for selecting the one of the stacks to be operated on by the feed mechanism.
  • the invention comprises a paper compartment having a fixed floor supporting a stack of paper of a given size and a shelf for supporting a stack of paper of different size over the first stack, the shelf being movable to position the second stack in or out of the path of the feed mechanism.
  • FIGURE 1 is a respective view of a typical photocopy machine incorporating the subject invention
  • FIGURE 2 is a side view of the machine of FIGURE 1 with parts broken away to show interior details;
  • FIGURE 3 is an enlarged top plan view of the paper storage compartment with the cover shown in the open position;
  • FIGURE 4 is a transverse section taken along line 4-4 of FIGURE 3.
  • FIGURE 5 is a perspective view of the movable shelf assembly shown removed from the remainder of the apparatus.
  • the machine 20 includes a housing 22 at the top of which is a paper storage compartment or magazine indicated generally at 24 which is normally closed by a top door 26 hinged to move from the full line position to the dotted line position shown in FIGURE 2. Since the present invention is concerned only with the paper storage compartment 24 and the mechanism indicated generally at 28 for feeding the paper from this compartment into the machine proper, additional details of the machine will be omitted. For such details and a complete description of the operation of the machine reference may be had to the aforesaid co-pending application Serial No. 249,248, now abandoned.
  • the paper storage compartment 24 has a sheet metal floor 38 having upwardly inclined entrance and exit portions 32 and 34, respectively.
  • the floor member 30 extends completely across the machine and at its opposite edges is anchored to vertical sidewalls 36 of the main machine housing.
  • a stack of paper, which is supported on the floor member 30, is confined between symmetrically opposite guide assemblies 38 and 40 shown in detail in FIGURES 3 and 4.
  • the guide assemblies each have a base portion 42 integrally joined to an upright portion 44.
  • the guide assemblies are mounted for adjustment laterally of the paper compartment to accommodate sheets of varying width.
  • the base members 42 carry a headed stud 46 which objects downwardly through a laterally extending slot 48 in the floor member 30, the slot being centrally enlarged as at 50 to permit removal of the guide assemblies.
  • the guides are frictionally held in their adjusted position by L-shaped clamp members 52 pivotally carried as at 54 on the vertical guide portions 44.
  • the clamp members 52 extend downwardly through the slot 48 and have a clamping portion 56 adapted to engage the underside of floor member 30 outwardly of the margins of the slot 48.
  • the clamp members 52 are normally biased to clamping position by springs 58, and may be released by manually pivoting their upper portions inwardly.
  • the guide assemblies 38 and 40 also carry friction pad assemblies 60 which cooperate to engage the edges of the stack of sheets to position the sheets accurately and to apply a light drag to hold the sheets against undesired axial movement.
  • the assemblies 60 each comprise a channel assembly 62 carried by a stud 64 which projects through a slot 66 in the guide member 44, the outer end of the stud being enlarged and knurled at 68 to provide a convenient means for clamping the assembly 60 in any adjusted position along the slot 66.
  • a friction pad '72 of foam rubber or like material is carried by a backing plate 74 which is resiliently urged to the position shown in FIGURE 3 by a spring (not shown).
  • a pin 78 attached to the backing plate 74 extends through the stud 64 and at its outer end is provided with an operating member '79 to permit retraction of the friction pad 72 to facilitate loading the paper.
  • the topmost sheet of the stack of paper positioned on the floor member 34 between the guide assemblies 38 and 40 is withdrawn from the paper compartment by a pair edge of the stack S of rubber covered feed rollers 80 and 82 rigid with a shaft 84, the opposite ends of which are supported on a pair of brackets 86 and 88.
  • the shaft 84 is driven by a pair of belts 90 and E12 driven by a drive shaft 94 (FIGURE 2) connected to the main machine drive by means which have been omitted for clarity.
  • the brackets 86 and 88 are pivotal about the axis of the shaft 94 so the brackets and shaft can be raised and lowered without disturbing the drive connection to the feed rollers 80 and 82.
  • the brackets, shaft and rollers are raised to the dotted line position of FIGURE 2 by pins 96 carried by the door hinge brackets 98, the pins engaging the undersides of the brackets 86 and 88.
  • the weight of the brackets 86 and 88, the shaft 84 and the rollers 80 and 82 is suflicient to provide the necessary friction on the upper surface of the stack of paper to cause the upper sheet to advance when the rollers 80 and 82 are rotated.
  • the remaining sheets are held in place by the friction pad assemblies 60'.
  • upper guide member 100 is provided to form with the exit portion 34 of the floor member 30 a throat 102 which prevents the passage of more than one sheet of paper at a time into the machine. After the paper leaves the throat 102 it is engaged by rollers 103 carried by the drive shaft 94 and cooperating rollers 104 driven by suitable means not shown.
  • the mechanism can be adapted to handle an additional stack of paper of the same or different size by the addition of the supplemental tray assembly indicated generally at 106 and shown separately in FIGURE 5.
  • the tray assembly is of one-piece construction formed from heavy gauge sheet metal.
  • the tray has a flat floor portion 108, upturned rear rail 110, upturned side rail portions 114 and 116, the forward portions of the latter having integral U-shaped guides 118 and 120 for a purpose to appear.
  • Forward guides 122 and 124 aligned with the rear guides 118 and .120, respectively, are also formed integrally with the tray assembly. Adjacent their forward ends, the side portions 114 and 116 carry channel members 126 and 128 in which rubber friction pads 130 and 132 mounted on backing plates 134 and 136 are received.
  • the friction pads 130 and 132 are biased outwardly by spring straps 138 and 140, respectively.
  • the tray assembly 106 is installed for use by first adjusting the guide assemblies 38 and 40 to proper lateral spacing and then slipping the guides 118-124 over the upper edges of the upright portions 44 of the guide assemblies 38 and 40. When so positioned the upper tray assembly 106 is capable of limited movement axially of the paper compartment 24.
  • a stack S of the larger paper is placed on the lower floor member 30 between the guide assemblies 38 and 40 with the front edge of the paper in position to be engaged by the drive rollers 80 and 82.
  • the tray assembly 106 is then put in position and loaded with a stack S of the smaller paper. If it is desired to feed the larger sheets of paper the upper tray assembly 106 is moved to the full line position shown in FIGURE 2 to place the forward out of the path of the drive rollers 80 and 82 when the door 26 is closed.
  • the apparatus will then feed the sheets from the stack S one at a time in the usual manner.
  • the tray assembly 106 When it is desired to feed the smaller :sheets the tray assembly 106 is advanced to the dotted line position shown in FIGURE 2 to place the leading edge of the stack S in the path of the rollers 80 and 82 as they are lowered when the door 2.6 is again closed.
  • the drive rollers 80' and 82 will thenv feed the smaller sheets of paper leaving the larger sheets completely undisturbed.
  • tray assemblies 106 of various sizes and length.
  • the tray assembly may be divided to provide for lateral adjustment in essentially the same manner as the lateral adjustment of the main side guides 38 and 40.
  • Apparatus for storing and feeding paper sheets comprising a paper storage compartment having a floor and an exit slot, feeding means normally adapted to engage and move through said slot the topmost one of a first stack of paper supported on said floor, shelf means movably mounted for supporting a separate second stack of paper within said compartment above said first stack, said shelf means being movable to selectively position said second stack in position to :be engaged by said feed means or permit said feed means to engage said first stack.
  • Apparatus for storing and feeding paper sheets comprising a paper storage compartment having a floor and an exit slot, vertically movable feed means gravity urged towards said floor, said feed means normally engaging the top of a first stack of paper supported on said floor, and shelf means movably mounted within said compartment adapted to selectively dispose a second stack of paper in position to be engaged by said feed means to thereby prevent engagement of said feed means with said first stack of paper.
  • Apparatus for storing and feeding paper sheets comprising a paper storage compartment having a floor; a hinged door and an exit slot, driven feed rollers within said compartment, means supporting said feeding rollers for vertical movement within said compartment, said feeding rollers being gravity urged toward a position for engagement with a first stack of paper supported on said floor, means operative when said door is opened to raise said rollers to a pre-determined height above said floor, shelf means for supporting a separate second stack of paper within said storage compartment over said first stack, said shelf means being movable to selectively dispose said second stack in position to be engaged by said feed rollers when said door is closed or to permit said rollers to engage said first stack of paper.
