Definitions

  • This invention is directed to a stacker for stacking envelopes received from a machine that has placed images on the envelopes, and more particularly, to an envelope stacking apparatus that stacks enveiopes on long edges thereof.
  • Simple catch boxes as for example, in FIG. 1, which most low capacity stackers employ, are N - 1 stackers, so that the user must perform a very tedious manual inversion of the envelopes in order to make the envelope printing order match the letter order that must be inserted into the envelopes. Therefore, if possible, the imaged or addressed side of envelopes should be stored 1 to N as shown in FIG. 2.
  • An object of the present invention is to provide a simple and cost effective envelope stacker.
  • the present invention provides an envelope stacker according to claim 1 of the appended claims.
  • the invention further provides an evelope stacker according to claim 5 of the appended claims
  • the invention further provides a printer according to claim 8 of the appended claims.
  • high capacity envelope stacker apparatus 100 is shown attached to an envelope feeding copier/printer, such as shown in allowed US-A-5,139,250 by John D. Zoltner and entitled OSCILLATING BLADE ENVELOPE ROTATOR, which is incorporated herein by reference to the extent necessary to practice the present invention.
  • the high capacity envelope stacker apparatus 100 of the present invention is used only part of the time an imaging apparatus, such as, a printer is in use. As such, it must be compact and unobtrusive from an appearance standpoint, and since it is not a dedicated part of the imaging apparatus, it must be inexpensive.
  • Such an envelope stacker is shown in FIG. 3 as 100 connected to an exemplary printer 30, such as the Xerox 4045®, that includes an envelope feeder 10.
  • Envelope feeder 10 is a high capacity (200 envelopes), gravity-fed, load-while-run (when a cover safety interlock is not used) apparatus which is adapted to be connected to a printer with a long dimension of the envelopes 8 placed against the end and short edge dimension of the printer for minimum footprint usage.
  • the envelopes are inserted flap down within walls of bin 13.
  • a planar bottom and envelope supporting portion of the bin has a relieved portion therein in the shape of an envelope flap that permits the flap of the lowermost envelope to extend thereinto.
  • a motor and brackets support a picker blade by way of a shaft (not shown) for back and forth or oscillatory movement within a predetermined space along the bottom surface of bin 13.
  • the blade (not shown) is rotated by the motor from a first or home position underlying bin 13 to a second position within printer 30.
  • the picker blade sweeps each envelope sideways and pivots them from a short edge dimension to a long edge dimension within the printer between guides 52 and 53.
  • Each envelope is then registered along its long edge with scuffer wheel 55 and fed out of the printer by feed rolls 60 into high capacity envelope stacking apparatus 100.
  • High capacity envelope stacker 100 of the present invention in FIGS. 3 - 5 accepts envelopes from copier/printer 30 at about a 30° angle and comprises a catch tray having side walls 101 and 102 and end walls 103 and 104 with the catch tray. being divided into an envelope receiving compartment 120 and an envelope storage compartment 110. The two compartments are separated by a slidable partition 113 and compartment 120 has a bottom shelf 121. Brush-like snubbers 118 are positioned on opposite sides of walls 101 and 102 for reasons that will be explained hereinafter.
  • a movably pivoting flipper plate 122 is positioned within compartment 120 and mounted by hinge 123 to be rotated through an arc of 90° from a position on top of bottom receiving shelf 121 past snubbers 118 by an actuator disc 125 driven by a motor (not shown).
  • Actuator disc 125 is connected to pivoting flipper plate 122 by an eccentrically mounted link 126.
  • envelopes exit the output or right end of copier/printer 30 as viewed in FIG. 3, at an angle of approximately 30° in the direction of arrow A of FIG. 4 and are received in receiving compartment 120 and coming to rest on flipper 122.
  • Envelopes pass a photosensor 40 in the exit path of copier/printer 30 which includes an emitter 41 and a detector or receiver 42.
  • the software of copier/printer 30 is designed such that a signal from sensor 40 that an envelope has passed that station is sent to the onboard computer of the copier/printer. After a predetermined delay, to allow the envelope to come to rest in the stacker on flipper plate 122, a signal is sent from the computer to actuate the motor that turns actuator disc 125 one revolution.
  • the resultant stacked envelopes from this operation are stacked (image side) 1 - N which is the desired sequence since copy sheets that are to be inserted into the envelopes are usually stacked 1 - N.
  • the advantages of this stacker apparatus over prior envelope stackers include the 1 - N order integrity; low-complexity; low unit manufacturing cost; user friendliness and safe operation.
  • FIGS. 6 and 7 An alternative embodiment of the high capacity envelope stacker in accordance with the present invention is shown in FIGS. 6 and 7 in which like numbers represent like elements of FIGS. 3 - 5.
  • envelopes 8 enter stacker 150 and rest flap side down on top of flipper plate 122 which is parallel to bottom shelf 153.
  • motor pulley 160 is actuated by a signal from the stacker logic circuit (not shown)
  • disc 155 is rotated by belt 161 in the direction of arrow D for one revolution for each envelope and pin 156 that is attached to disc 155 lifts flipper plate 122 which is spring loaded down and envelope 8 past brushes 118 onto a long edge thereof and against stopper plate 170.
  • the action of flipper plate 122 pushes the envelopes and movable support 154 along rails or tubular slides 111 in the direction of arrows B toward end member 152 and away from end member 151.
  • the stacker apparatus of FIG. 7 is the same as that shown in FIG. 6 except that pin 156 is shown captured within a bracket 130 connected to the underside of flipper plate 122. As a result, rotation of disc 155 causes pin 156 to ride within bracket 130 to thereby raise and lower flipper plate 122 in order to stack incoming envelopes.
